* emacs.c (shut_down_emacs): Don't assume stderr is buffered,
[bpt/emacs.git] / src / ChangeLog
1 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2
3 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4 or that fprintf is async-signal-safe. POSIX doesn't require
5 either assumption.
6
7 2012-09-22 Chong Yidong <cyd@gnu.org>
8
9 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
10 (Bug#8207).
11
12 2012-09-22 Kenichi Handa <handa@gnu.org>
13
14 * composite.c (composition_reseat_it): Handle the case that a
15 grapheme cluster is not covered by a single font (Bug#12352).
16
17 2012-09-21 Chong Yidong <cyd@gnu.org>
18
19 * image.c (define_image_type): Avoid adding duplicate types to
20 image_types (Bug#12463). Suggested by Jörg Walter.
21
22 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
23
24 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
25 (print_load_command_name): Add case LC_DATA_IN_CODE.
26 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
27
28 2012-09-21 Glenn Morris <rgm@gnu.org>
29
30 * eval.c (Frun_hook_with_args_until_success)
31 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
32
33 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
34
35 * fileio.c (Ffile_selinux_context): Only call freecon when
36 lgetfilecon succeeded.
37 (Fset_file_selinux_context): Likewise. (Bug#12444)
38
39 2012-09-21 Eli Zaretskii <eliz@gnu.org>
40
41 * xdisp.c (try_window_reusing_current_matrix): Under bidi
42 reordering, locate the cursor by calling set_cursor_from_row; if
43 that fails, clear the desired glyph matrix before returning a
44 failure indication to the caller. Fixes leaving garbled display
45 when fast scrolling with a down-key. (Bug#12403)
46 (compute_stop_pos_backwards): Fix a typo that caused crashes while
47 scrolling through multibyte text.
48
49 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
50
51 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
52 calling mark_vectorlike since that's the one that marks the window.
53 (mark_discard_killed_buffers): Mark the final cdr.
54 * window.h (struct window): Move prev/next_buffers to the
55 non-standard fields.
56 * window.c (make_window): Initialize prev/next_buffers manually.
57
58 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
59
60 Omit unused arg EXPECTED from socket hooks.
61 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
62 * nsterm.m (ns_term_init):
63 * termhooks.h (struct terminal.read_socket_hook):
64 * w32inevt.c (w32_console_read_socket):
65 * w32term.c (w32_read_socket):
66 * xterm.c (XTread_socket):
67 Omit unused arg EXPECTED. All callers changed.
68 (store_user_signal_events): Return void, not int, since callers no
69 longer care about the return value. All uses changed.
70
71 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
72
73 * w32gui.h (XParseGeometry): Do not declare.
74
75 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
76
77 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
78 Ignore 'expected'. See Eli Zaretskii in
79 <http://bugs.gnu.org/12471#8> (last line).
80
81 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
82 (XParseGeometry): Now static. Substitute extremal values for
83 values that are out of range.
84
85 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
86
87 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
88
89 * nsfns.m (XParseGeometry): Remove.
90 (Fx_create_frame): Call x_set_offset to correctly interpret
91 top_pos in geometry.
92
93 * frame.c (read_integer, XParseGeometry): Moved from w32xfns.c.
94 (Fx_parse_geometry): If there is a space in string, call
95 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
96
97 2012-09-17 Eli Zaretskii <eliz@gnu.org>
98
99 * search.c (scan_buffer): Use character positions in calls to
100 region_cache_forward and region_cache_backward, not byte
101 positions. (Bug#12196)
102
103 * w32term.c (w32_read_socket): Set pending_signals to 1, like
104 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
105
106 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
107 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
108 emacs_blocked_malloc, now deleted.
109
110 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
111
112 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
113 The workaround was for improving performance on Solaris 2.4, but
114 is getting in the way now. Emacs will still work if someone is
115 still running Solaris 2.4 in a museum somewhere; Sun dropped
116 support for Solaris 2.4 in 2003.
117 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
118 * process.c (create_process) [HAVE_WORKING_VFORK]:
119 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
120 since Emacs no longer uses vfork on that platform.
121
122 2012-09-17 Glenn Morris <rgm@gnu.org>
123
124 * emacs.c: Use COPYRIGHT.
125
126 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
127
128 Remove configure's --without-sync-input option (Bug#12450).
129 When auditing signal-handling in preparation for cleaning it up,
130 I found that SYNC_INPUT has race conditions and would be a real
131 pain to fix. Since it's an undocumented and deprecated
132 configure-time option, now seems like a good time to remove it.
133 Also see <http://bugs.gnu.org/11080#16>.
134 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
135 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
136 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
137 (malloc_hysteresis):
138 (check_depth) [XMALLOC_OVERRUN_CHECK]:
139 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
140 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
141 (dont_register_blocks, bytes_used_when_reconsidered)
142 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
143 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
144 [!SYSTEM_MALLOC && !SYNC_INPUT]:
145 Remove. All uses removed.
146 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
147 implementation, one that depends on whether the new macro
148 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
149 is defined.
150 * atimer.c (run_timers, handle_alarm_signal):
151 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
152 (handle_async_input, process_pending_signals)
153 (handle_input_available_signal, init_keyboard):
154 * nsterm.m (ns_read_socket):
155 * process.c (wait_reading_process_output):
156 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
157 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
158 (emacs_write):
159 * xterm.c (XTread_socket):
160 Assume SYNC_INPUT.
161 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
162 * eval.c (handling_signal): Remove. All uses removed.
163 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
164 All uses replaced with the SYNC_INPUT version.
165 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
166 Remove decls.
167 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
168 Now static.
169
170 * font.c (Ffont_shape_gstring): Remove unused local.
171
172 2012-09-16 Glenn Morris <rgm@gnu.org>
173
174 * Makefile.in (clean): No longer run nextstep's clean.
175
176 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
177 (ns_frag): Remove.
178 (ns-app): Move here from ns.mk, and simplify.
179 (clean): Simplify nextstep entry.
180 * ns.mk: Remove file.
181
182 2012-09-17 Kenichi Handa <handa@gnu.org>
183
184 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
185 not covert the last few charactes.
186
187 2012-09-16 Kenichi Handa <handa@gnu.org>
188
189 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
190 here, but just check the validity of glyphs in the glyph-string.
191
192 2012-09-16 Martin Rudalics <rudalics@gmx.at>
193
194 * window.c (Fwindow_parameter, Fset_window_parameter): Accept
195 any window as argument (Bug#12452).
196
197 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
198
199 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
200 to ns_term_init to avoid memory leak.
201
202 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
203 explicit retain/release.
204 (ns_term_init): Only allow one display. Initialize outerpool and
205 ns_*_types.
206
207 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
208
209 Port _setjmp fix to POSIXish hosts as well as Microsoft.
210 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
211 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
212 the Microsoft problem in a different way, by altering ../nt/config.nt.
213
214 2012-09-15 Eli Zaretskii <eliz@gnu.org>
215
216 * w32xfns.c:
217 * w32uniscribe.c:
218 * w32term.c:
219 * w32select.c:
220 * w32reg.c:
221 * w32proc.c:
222 * w32menu.c:
223 * w32inevt.c:
224 * w32heap.c:
225 * w32font.c:
226 * w32fns.c:
227 * w32console.c:
228 * w32.c:
229 * w16select.c: Remove inclusion of setjmp.h, as it is now included
230 by lisp.h. This completes removal of setjmp.h inclusion
231 erroneously announced in the previous commit. (Bug#12446)
232
233 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
234 more accurate.
235
236 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
237 not defined as a macro. The latter happens on MS-Windows.
238 (Bug#12446)
239
240 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
241
242 Port better to POSIX hosts lacking _setjmp (Bug#12446).
243 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
244 Some instances of '#include <setjmp.h>' removed, if the
245 only reason for the instance was because "lisp.h" was included.
246 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
247 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
248 and _longjmp with the new symbols. Emacs already uses _setjmp if
249 available, so this change affects only POSIXish hosts that have
250 sigsetjmp but not _setjmp, such as some versions of Solaris and
251 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
252 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
253 (png_load_body) [HAVE_PNG]:
254 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
255 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
256 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
257 since PNG requires jmp_buf. This is the only exception to the
258 general rule that we now use sys_setjmp and sys_longjmp.
259 This exception is OK since this code does not change the signal
260 mask or longjmp out of a signal handler.
261
262 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
263
264 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
265 Include "syssignal.h", for 'main_thread'.
266
267 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
268
269 Avoid out-of-range marker position (Bug#12426).
270 * insdel.c (replace_range, replace_range_2): Adjust
271 markers before overlays, as suggested by comments.
272 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
273 Remove redundant check before calling offset_intervals.
274
275 2012-09-14 Martin Rudalics <rudalics@gmx.at>
276
277 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
278 current buffer (Bug#12387).
279
280 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
281
282 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
283
284 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
285
286 Use a more backwards-compatible timer format (Bug#12430).
287 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
288 vector element, not from the 4th, since PSECS is now at the end.
289 (Fcurrent_idle_time): Doc fix.
290
291 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
292
293 Function to mark objects and remove killed buffers at once.
294 * alloc.c (discard_killed_buffers): Rename to ...
295 (mark_discard_killed buffers) ... new name. Add marking
296 of remaining objects. Fix comment. Adjust users.
297 (mark_object): Do not touch frame buffer lists here.
298 * frame.c (delete_frame): Reset frame buffer lists here.
299
300 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
301
302 Better workaround for GNOME bug when --enable-gcc-warnings.
303 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
304 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
305 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
306
307 Simplify SIGIO usage (Bug#12408).
308 The code that dealt with SIGIO was crufty and confusing, e.g., it
309 played tricks like "#undef SIGIO" but these tricks were not used
310 consistently. Simplify mostly by not #undeffing standard symbols,
311 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
312 or not as we please) rather than "defined SIGIO" (standard symbol
313 that we probably shouldn't #undef).
314 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
315 Modules that need it can include it.
316 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
317 * dispextern.h (ignore_sigio): New decl.
318 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
319 unconditionally, since it's now a no-op if !USABLE_SIGIO.
320 * emacs.c (shut_down_emacs):
321 * keyboard.c (kbd_buffer_store_event_hold):
322 Use ignore_sigio rather than invoking 'signal' directly.
323 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
324 for FIONREAD.
325 (FIONREAD, SIGIO): Do not #undef.
326 (tty_read_avail_input): Use #error rather than a syntax error.
327 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
328 for I_PIPE, used by SETUP_SLAVE_PTY.
329 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
330 * sysdep.c (croak): Remove; no longer needed. This bit of
331 temporary code, with Fred N. Fish's comment that it's temporary,
332 has been in Emacs since at least 1992!
333 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
334 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
335 * syssignal.h (croak): Remove decl.
336 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
337 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
338 now that we're termios-only.
339 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
340 * term.c (dissociate_if_controlling_tty): Use #error rather than
341 a run-time error.
342
343 Work around GCC and GNOME bugs when --enable-gcc-warnings.
344 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
345 to work around GNOME bug 683906.
346 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
347 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
348 This works around GCC bug 54561.
349
350 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
351
352 More fixes for 'volatile' and setjmp/longjmp.
353 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
354 * image.c (struct png_load_context) [HAVE_PNG]: New type.
355 (png_load_body) [HAVE_PNG]:
356 (jpeg_load_body) [HAVE_JPEG]:
357 New function, with most of the old parent function's body.
358 (png_load) [HAVE_PNG]:
359 (jpeg_load) [HAVE_JPEG]:
360 Invoke the new function, to avoid longjmp munging our locals.
361 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
362 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
363 longjmp is passed 2, as the C standard doesn't guarantee this.
364 Instead, store the failure code into mgr->failure_code.
365
366 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
367
368 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
369 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
370 (syms_of_keyboard): Remove support for unread-command-char.
371
372 2012-09-12 Eli Zaretskii <eliz@gnu.org>
373
374 * w32proc.c (sys_kill): If PID is our process ID and the signal is
375 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
376 violation. (Bug#12426)
377
378 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
379
380 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
381
382 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
383
384 * eval.c: Add `inhibit-debugger'.
385 (Qinhibit_debugger): New symbol.
386 (call_debugger): Bind it instead of Qdebug_on_error.
387 (maybe_call_debugger): Test Vinhibit_debugger.
388 (syms_of_eval): Define inhibit-debugger.
389 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
390 (syms_of_xdisp): Remove inhibit-debug-on-message.
391
392 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
393
394 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
395 If a nonvolatile local variable is written before a _longjmp to
396 the frame containing the variable, and is read after the _longjmp,
397 the value read is indeterminate. Some local variables of type
398 'struct handler' and 'struct catchtag' are used in this way, so
399 mark each of their slots as volatile if the slot can be set before
400 _longjmp and read afterwards.
401 * lisp.h (struct handler): var and chosen_clause are now volatile.
402 (struct catchtag): val, next, and pdlcount are now volatile.
403
404 * bidi.c (bidi_push_it, bidi_pop_it):
405 * fns.c (copy_hash_table):
406 * image.c (define_image_type):
407 * keyboard.c (kbd_buffer_store_event_hold):
408 * process.c (Fprocess_send_eof):
409 * xfaces.c (x_create_gc) [HAVE_NS]:
410 * xgselect.c (xg_select):
411 Prefer assignment to memcpy when either will do.
412
413 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
414 Use pointer-to-a-pointer to simplify and avoid a NILP check each
415 time an item is removed. No need to mark this function 'inline';
416 the compiler knows better than we do.
417
418 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
419
420 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
421 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
422 to change_frame_size (Bug#12388).
423 (windowDidResize:): Pass YES to updateFrameSize.
424
425 * nsterm.h: Add delay parameter to updateFrameSize.
426
427 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
428
429 Discard killed buffers from deleted window and frame objects.
430 This reduces an amount of references to killed buffers and
431 helps GC to reclaim them faster.
432 * alloc.c (discard_killed_buffers): New function.
433 (mark_object): Use it for deleted windows and frames.
434 (mark_object): If symbol's value is set up for a killed buffer
435 or deleted frame, restore it's global binding.
436 * data.c (swap_in_global_binding): Add GC notice.
437 (swap_in_symval_forwarding): Use convenient set_blv_where.
438 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
439 * window.h: ... to here.
440
441 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
442
443 Convenient macro to check whether the buffer is live.
444 * buffer.h (BUFFER_LIVE_P): New macro.
445 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
446 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
447
448 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
449
450 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
451 composition cases (Bug#12364).
452
453 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
454 overhang of succeeding glyphs overlapping box cursor.
455
456 * w32term.c (x_draw_glyph_string): Likewise.
457
458 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
459
460 Simplify, document, and port floating-point (Bug#12381).
461 The porting part of this patch fixes bugs on non-IEEE platforms
462 with frexp, ldexp, logb.
463 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
464 Now static.
465 * floatfns.c: Simplify discussion of functions that Emacs doesn't
466 support, by removing commented-out code and briefly listing the
467 C89 functions excluded. The commented-out stuff was confusing
468 maintenance, e.g., we thought we needed cbrt but it was commented out.
469 (logb): Remove decl; no longer needed.
470 (isfinite): New macro, if not already supplied.
471 (isnan): Don't replace any existing macro.
472 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
473 are present on all C89 platforms.
474 (Ffrexp): Do not special-case zero, as frexp does the right thing
475 for that case.
476 (Flogb): Do not use logb, as it doesn't have the desired meaning
477 on hosts that use non-base-2 floating point. Instead, stick with
478 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
479 frexp, to avoid getting an unspecified result.
480
481 * xdisp.c (Qinhibit_debug_on_message): Now static.
482
483 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
484
485 * nsterm.m (ns_update_begin): Set clip path to whole view by using
486 NSBezierPath (Bug#12131).
487
488 2012-09-10 Chong Yidong <cyd@gnu.org>
489
490 * fns.c (Fdelq, Fdelete): Doc fix.
491
492 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
493
494 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
495 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
496
497 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
498
499 * lisp.h (make_lisp_ptr): New macro to replace XSET.
500 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
501 Use it.
502
503 2012-09-09 Eli Zaretskii <eliz@gnu.org>
504
505 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
506 left fringe if the window has a left margin. This avoids leaving
507 traces of the cursor because its leftmost pixel is not drawn over.
508
509 * dispnew.c (update_window_line): When the left margin area of a
510 screen line is updated, set the redraw_fringe_bitmaps_p flag of
511 that screen line. (Bug#12277)
512
513 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
514
515 Assume C89 or later for math functions (Bug#12381).
516 This simplifies the code, and makes it a bit smaller and faster,
517 and (most important) makes it easier to clean up signal handling
518 since we can stop worring about floating-point exceptions in
519 library code. That was a problem before C89, but the problem
520 went away many years ago on all practical Emacs targets.
521 * data.c, image.c, lread.c, print.c:
522 Don't include <math.h>; no longer needed.
523 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
524 might be autoconfigured, as that never happens.
525 * data.c (fmod):
526 * doprnt.c (DBL_MAX_10_EXP):
527 * print.c (DBL_DIG):
528 Remove. C89 or later always defines these.
529 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
530 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
531 (arith_error, domain_error, domain_error2):
532 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
533 no longer needed -- we simply return what C returns. All uses removed.
534 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
535 the wrapped code.
536 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
537 Remove. All uses expanded, as these macros are no longer used
538 more than once and are now more trouble than they're worth.
539 (Ftan): Use tan, not sin / cos.
540 (Flogb): Assume C89 frexp.
541 (fmod_float): Assume C89 fmod.
542 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
543 (init_floatfns): Remove. All uses removed.
544
545 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
546
547 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
548 compositeToPoint for OSX < 10.6 (Bug#12390).
549
550 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
551
552 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
553 This produces more-accurate results.
554
555 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
556
557 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
558 changes (Bug#12088).
559
560 2012-09-08 Chong Yidong <cyd@gnu.org>
561
562 * syntax.c (Fstring_to_syntax): Doc fix.
563
564 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
565
566 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
567 in the internal border.
568 (x_set_window_size): Remove static variables and their usage.
569 (ns_redraw_scroll_bars): Fix NSTRACE arg.
570 (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove
571 fringe/internal border adjustment (Bug#11052).
572 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
573 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
574 (ns_fix_rect_ibw): Remove.
575 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
576 (ns_dumpglyphs_box_or_relief): Ditto.
577 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
578 adjustment.
579 (ns_dumpglyphs_image): Ditto.
580 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
581 border adjustment.
582 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
583 their usage. Add fringe_extended_p and its use as in other terms.
584 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
585 scroll bar was removed.
586 (updateFrameSize): New function.
587 (windowDidResize): Move code to updateFrameSize and call it.
588
589 * nsterm.h (EmacsView): Add updateFrameSize.
590
591 2012-09-07 Chong Yidong <cyd@gnu.org>
592
593 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
594
595 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
596
597 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
598
599 More signal-handler cleanup (Bug#12327).
600 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
601 Problem introduced when merging patches. Noted by Eli Zaretskii in
602 <http://bugs.gnu.org/12327#67>.
603 * floatfns.c: Comment fix.
604 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
605 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
606 and anyway the declaration is harmless even if SIGDANGER is not defined.
607 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
608 defined BROKEN_FIONREAD). systty.h formerly did this, but other
609 source files not surprisingly expected syssignal.h to define, or
610 not define, SIGIO, and it's cleaner to do it that way, for consistency.
611 Include <sys/ioctl.h>, for FIONREAD.
612 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
613 This eliminates a problem whereby other files mysteriously had
614 to include "syssignal.h" before including "systty.h" if they
615 wanted to use "#ifdef SIGIO".
616
617 2012-09-07 Eli Zaretskii <eliz@gnu.org>
618
619 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
620
621 * w32.c (sigemptyset): Empty the set.
622 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
623
624 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
625
626 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
627
628 * alloc.c (mark_buffer): Revert unsafe marking optimization.
629 (mark_object): Likewise for frame objects.
630
631 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
632
633 * syssignal.h (handle_on_main_thread): Always declare,
634 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
635 This ports to platforms without HAVE_PTHREAD.
636
637 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
638
639 Signal-handler cleanup (Bug#12327).
640 Emacs's signal handlers were written in the old 4.2BSD style with
641 sigblock and sigmask and so forth, and this led to some
642 inefficiencies and confusion. Rewrite these to use
643 pthread_sigmask etc. without copying signal sets around. Also,
644 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
645 'signal', and instead use functions that do not attempt to take
646 over the system name space. This patch causes Emacs's text
647 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
648 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
649 Do not include <signal.h> or "syssignal.h", as these
650 modules do not use signals.
651 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
652 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
653 Do not include <signal.h>, as "syssignal.h" does that for us now.
654 * atimer.c (sigmask_atimers): New function.
655 (block_atimers, unblock_atimers): New functions,
656 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
657 All uses replaced.
658 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
659 no longer needed here.
660 * emacs.c (main): Inspect existing signal handler with sigaction,
661 so that there's no need to block and unblock SIGHUP.
662 * sysdep.c (struct save_signal): New member 'action', replacing
663 old member 'handler'.
664 (save_signal_handlers, restore_signal_handlers):
665 Use sigaction instead of 'signal' to save and restore.
666 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
667 New function. All users of 'signal' modified to use set_sighandler
668 if they're writeonly, and to use sys_signal if they're read+write.
669 (emacs_sigaction_init, forwarded_signal): New functions.
670 (sys_signal): Remove. All uses replaced by calls to sigaction
671 and emacs_sigaction_init, or by direct calls to 'signal'.
672 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
673 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
674 all uses replaced by pthread_sigmask etc. calls.
675 * syssignal.h: Include <signal.h>.
676 (emacs_sigaction_init, forwarded_signal): New decls.
677 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
678 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
679 (sigmask, sys_sigmask): Remove; no longer needed.
680 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
681 (sigblock, sigunblock, sigfree):
682 (sigsetmask) [!defined sigsetmask]:
683 Remove. All uses replaced by pthread_sigmask.
684 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
685 no longer need to be replaced, and its typical old uses
686 are now done via emacs_sigaction_init and sigaction.
687 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
688 (sys_sigdel): Remove; unused.
689 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
690
691 2012-09-06 Eli Zaretskii <eliz@gnu.org>
692
693 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
694 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
695
696 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
697
698 Explicitly mark buffer_defaults and buffer_local_symbols.
699 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
700 mark_local_symbols here.
701 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
702 since special buffers aren't marked here any more.
703 (allocate_buffer): Chain new buffer with all_buffers here...
704 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
705 not here.
706 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
707 (syms_of_buffer): Remove staticpro of the above.
708 (init_buffer_once): Set names for buffer_defaults and
709 buffer_local_symbols.
710
711 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>

716 (generate_otf_features, font_check_otf_features, font_check_otf)
717 (font_match_p, font_list_entities, font_at):

719 (fontset_find_font, Fset_fontset_font)
720 (face_suitable_for_char_p) [0]:
721 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
722 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
723 (m17n_flt_initialized, ftfont_shape_by_flt):
724 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
725 * nsfont.m (nsfont_draw):
726 * w32font.c (w32font_draw):
727 * w32term.c (x_draw_glyphless_glyph_string_foreground):
728 Use bool for booleans.
729 * font.h: Adjust to above API changes.
730 (struct font, struct font_driver, struct font_driver_list):
731 Use bool for booleans.
732 (struct font): Remove useless member encoding_type.
733 All users removed.
734 * fontset.c, xftfont.c: Omit unnecessary static decls.
735
736 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
737
738 * alloc.c (mark_object): Revert window marking code
739 since it's unsafe for the Fset_window_configuration.
740
741 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
742
743 Fix race conditions with signal handlers and errno (Bug#12327).
744 Be more systematic about preserving errno whenever a signal
745 handler returns, even if it's not in the main thread. Do this by
746 renaming signal handlers to distinguish between signal delivery
747 and signal handling. All uses changed.
748 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
749 * data.c (deliver_arith_signal): Rename from arith_error.
750 * dispnew.c (deliver_window_change_signal): Rename from
751 window_change_signal.
752 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
753 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
754 * keyboard.c (deliver_input_available_signal): Rename from
755 input_available_signal.
756 (deliver_user_signal): Rename from handle_user_signal.
757 (deliver_interrupt_signal): Rename from interrupt_signal.
758 * process.c (deliver_pipe_signal): Rename from send_process_trap.
759 (deliver_child_signal): Rename from sigchld_handler.
760 * atimer.c (handle_alarm_signal):
761 * data.c (handle_arith_signal):
762 * dispnew.c (handle_window_change_signal):
763 * emacs.c (handle_fatal_signal, handle_danger_signal):
764 * keyboard.c (handle_input_available_signal):
765 * keyboard.c (handle_user_signal, handle_interrupt_signal):
766 * process.c (handle_pipe_signal, handle_child_signal):
767 New functions, with the actual signal-handling code taken from the
768 original respective signal handlers, sans the sporadic attempts to
769 preserve errno, since that's now done by handle_on_main_thread.
770 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
771 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
772 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
773 Move to sysdep.c.
774 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
775 Move initialization of main_thread to sysdep.c's init_signals.
776 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
777 our usage, and simplifies the mainline code.
778 (record_child_status_change): New static function, as a helper
779 for handle_child_signal, and with most of the old child handler's
780 contents.
781 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
782 (handle_child_signal): Use the above.
783 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
784 Moved here from emacs.c.
785 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
786 code moved here from emacs.c's main function.
787 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
788 replacing the old SIGNAL_THREAD_CHECK. All uses changed. This
789 lets callers save and restore errno properly.
790
791 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
792
793 Remove redundant or unused things here and there.
794 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
795 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
796 * editfns.c (Fcompare_buffer_substrings): Likewise.

805 (mark_object): Likewise for windows and frames.
806
807 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
808
809 * alloc.c (valid_lisp_object_p): Treat killed buffers,
810 buffer_defaults and buffer_local_symbols as valid objects.
811 Return special value to denote them.
812
813 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
814
815 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
816 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
817 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
818 (file_name_absolute_p, Fsubstitute_in_file_name):
819 (check_executable, check_writable, Ffile_accessible_directory_p)

821 (Finsert_file_contents, choose_write_coding_system)
822 (Fwrite_region, build_annotations, a_write, e_write)
823 (Fdo_auto_save):

825 (get_boot_time_1, lock_file_1, within_one_second):
826 * floatfns.c (in_float):
827 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
828 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
829 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
830 * lisp.h (struct Lisp_Hash_Table.cmpfn):
831 * window.c (compare_window_configurations):
832 Use bool for booleans.
833 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
834 (Fdefault_file_modes): Now mode_t, not int, for modes.
835 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
836 (internal_delete_file): Now returns void, not a (boolean) int,
837 since nobody was looking at the return value.
838 * lisp.h, window.h: Adjust to above API changes.
839
840 * xdisp.c (set_message): Simplify and reindent last change.
841
842 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
843
844 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
845
846 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
847
848 * eval.c (call_debugger): Make the function non-static so that we
849 can call it from set_message.
850
851 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
852 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
853
854 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
855
856 Give more-useful info on a fatal error (Bug#12328).
857 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
858 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
859 of doing the work ourselves.
860 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
861 do most of the work.
862 (fatal_error_backtrace): New function, taken from the guts
863 of the old fatal_error_signal, but with a new option to output
864 a backtrace.
865 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
866 info about the signal than just its number.
867 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
868 * sysdep.c: Include <execinfo.h>
869 (emacs_backtrace): New function, taken partly from the previous
870 code of the 'die' function.
871 (emacs_abort): Call fatal_error_backtrace rather than abort.
872
873 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
874
875 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
876 eager (load-time) macro-expansion.
877 * lisp.mk (lisp): Add macroexp.
878
879 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
880
881 Simplify redefinition of 'abort' (Bug#12316).
882 Do not try to redefine the 'abort' function. Instead, redo
883 the code so that it calls 'emacs_abort' rather than 'abort'.
884 This removes the need for the NO_ABORT configure-time macro
885 and makes it easier to change the abort code to do a backtrace.
886 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
887 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
888 Remove; sysdep.c's emacs_abort now takes its place.
889 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
890 'abort' changed to use 'emacs_abort'.
891 * msdos.c (dos_abort) [defined abort]: Remove; not used.
892 (abort) [!defined abort]: Rename to ...
893 (emacs_abort): ... new name.
894 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
895 the place of the old 'abort' in emacs.c.
896 * w32.c, w32fns.c (abort): Do not #undef.
897 * w32.c (emacs_abort): Rename from w32_abort.
898
899 2012-09-04 Eli Zaretskii <eliz@gnu.org>
900
901 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
902 offsets[j].dv, since the y axis of the screen coordinates points
903 down, while the y axis of the font definition coordinates points
904 up. This fixes display of Arabic diacritics such as KASRA and
905 KASRATAN. (Bug#11860)
906
907 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
908
909 Be more systematic about _setjmp vs setjmp.
910 * alloc.c (test_setjmp, mark_stack):
911 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
912 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
913 (png_load, my_error_exit, jpeg_load):
914 * process.c (send_process_trap, send_process):
915 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
916 The underscored versions are up to 30x faster on some hosts.
917 Formerly, the code used setjmp+longjmp sometimes and
918 _setjmp+_longjmp at other times, with no particular reason to
919 prefer setjmp+longjmp.
920
921 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
922
923 Fix minor problem found by static checking.
924 * buffer.c (Fdelete_all_overlays): Return nil.
925
926 2012-09-03 Martin Rudalics <rudalics@gmx.at>
927
928 * buffer.c (Fdelete_all_overlays): New function.
929
930 2012-09-03 Chong Yidong <cyd@gnu.org>
931
932 * gtkutil.c: Add extern decl for Qxft.
933
934 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
935
936 * emacs.c, eval.c: Use bool for boolean.
937 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

949 * eval.c (interactive_p): Omit always-true boolean argument
950 EXCLUDE_SUBRS_P. All callers changed.
951 * dispextern.h, lisp.h: Reflect above API changes.
952 * firstfile.c (dummy): Use the address of 'main', whose signature
953 won't change, instead of the address of 'initialize', whose
954 signature just changed from int to bool.
955 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
956 * msdos.c (fatal_error_in_progress): ... from here.
957 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
958 of incrementing it.
959 (redisplay_internal, unwind_redisplay): Simply clear
960 REDISPLAYING_P when unwinding, instead of saving its previous,
961 always-false value and then restoring it.
962
963 Clean up some extern decls.
964 Mostly, this hoists extern decls out of .c files and into .h files.
965 That way, we're more likely to catch errors if the interfaces change.
966 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
967 declare xg_mark_data.
968 * dispextern.h (x_frame_parm_handlers):
969 * font.h (Qxft):
970 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

984 * widget.c (free_frame_faces):
985 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
986 * xfont.c (x_clear_errors):
987 * xterm.c (x_frame_parm_handlers):
988 Remove now-redundant extern decls.
989 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
990 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
991 Now static.
992 * xfaces.c: Remove unnecessary static decls.
993 * xterm.c (updating_frame): Remove decl of nonexistent object.
994
995 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
996 when building globals.h, as the objects that are not built on
997 this host are not needed to compile C files on this host.
998
999 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
1000
1001 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

1006
1007 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.
1008 * doc.c (read_bytecode_char, get_doc_string, reread_doc_file)
1009 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)

1028 (set_intervals_multibyte_1, set_intervals_multibyte):
1029 * keyboard.c (decode_timer):
1030 Use bool for boolean.
1031 * intervals.h, lisp.h, systime.h: Reflect above API changes.

1037 (Bug#11758).
1038

1040
1041 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
1042 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

1048
1049 2012-09-01 Eli Zaretskii <eliz@gnu.org>
1050
1051 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
1052 more than one grapheme cluster passed to the shaper: compute the
1053 offset adjustment values separately for each cluster. (Bug#11860)
1054
1055 * image.c: Restore mistakenly removed inclusion of w32.h. Without
1056 it, GCC doesn't see prototypes of w32_delayed_load, and complains
1057 about implicit conversions from integer to pointer.
1058
1059 2012-09-01 Daniel Colascione <dancol@dancol.org>
1060
1061 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
1062 system used too early.
1063
1064 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>

1081 all of which have been moved to common code.
1082
1083 * xfaces.c: Include TERM_HEADER instead of listing all possible
1084 window-system headers.
1085
1086 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
1087 to match header.
1088
1089 * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
1090 directly accessing frame internals.

1095 * process.c: Include TERM_HEADER instead of listing all possible
1096 window-system headers.
1097
1098 * nsterm.h: Remove declarations now in frame.h. Define

1100
1101 * menu.c: Include TERM_HEADER instead of listing all possible
1102 window-system headers.
1103
1104 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
1105 window system.
1106
1107 * keyboard.c: Include TERM_HEADER instead of listing all possible
1108 window-system headers.
1109
1110 * image.c: Include TERM_HEADER instead of listing all possible

1139
1140 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
1141 the current window system; include in list of objects to link into
1142 Emacs.

1147 * lisp.h (mark_ttys): Remove prototype.
1148 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
1149 to mark_ttys because all possible values of 'top_frame' slot are
1150 the frames which are reachable from Vframe_list.
1151 * term.c (mark_ttys): Remove.
1152 (init_tty): Safely initialize 'top_frame' slot with Qnil.

1159 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
1160 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
1161 bitfields from unsigned char to unsigned.
1162
1163 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
1164
1165 Remove unused member of struct x_output and struct w32_output.

1180
1181 * lread.c (init_lread): For out-of-tree builds, only add the
1182 source directory's site-lisp dir to the load-path if it exists,
1183 consistent with in-tree builds. (Bug#12302)
1184
1185 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
1186
1187 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
1188 button_values to NULL. Call setStykeMask so dialogs get a close button.
1189 (windowShouldClose:): Set window_closed.
1190 (dealloc): New member, free button_values.
1191 (process_dialog:): Make member function. Remove window argument,
1192 replace window with self. Count buttons and allocate and store values
1193 in button_values.
1194 (addButton:value:row:): value is int with the name tag. Call setTag
1195 with tag. Remove return self, declare return value as void.
1196 (addString:row:): Remove return self, declare return value as void.
1197 (addSplit): Remove return self, declare return value as void.
1198 (clicked:): Remove return self, declare return value as void.

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

1273 (do_pending_window_change, change_frame_size)
1274 (change_frame_size_1, sit_for):
1275 Use bool for boolean.
1276 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
1277 and remove last int (actually boolean) argument, which was always 0.
1278 All callers changed.
1279 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
1280 * dispextern.h (struct composition_it): Use bool for boolean.
1281 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
1282 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
1283 * dired.c (file_name_completion):
1284 Use bool for boolean. (This was missed in an earlier change.)
1285
1286 2012-08-27 Martin Rudalics <rudalics@gmx.at>
1287
1288 * window.c (Fset_window_configuration): Revert first part of
1289 last change.
1290
1291 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
1292
1293 * nsterm.h (NSPanel): New class variable dialog_return.
1294
1295 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
1296 dialog_return.
1297 (windowShouldClose:): Use stop instead of stopModalWithCode.
1298 (clicked:): Ditto, and also set dialog_return (Bug#12258).
1299 (timeout_handler:): Use stop instead of abortModal. Send a dummy
1300 event.
1301 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
1302 modal loop returns.
1303
1304 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
1305
1306 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.
1307 * composite.c (find_composition, composition_gstring_p)
1308 (composition_reseat_it, find_automatic_composition):
1309 * data.c (let_shadows_buffer_binding_p)
1310 (let_shadows_global_binding_p, set_internal, make_blv)

1312 (Fmake_variable_frame_local, arithcompare, cons_to_unsigned)
1313 (cons_to_signed, arith_driver):
1314 * dbusbind.c (xd_in_read_queued_messages):
1315 * dired.c (directory_files_internal, file_name_completion):
1316 Use bool for booleans.
1317 * dired.c (file_name_completion):
1318 * process.h (fd_callback):
1319 Omit int (actually boolean) argument. It wasn't being used.
1320 All uses changed.
1321 * composite.h, lisp.h: Reflect above API changes.
1322
1323 * cmds.c, coding.c: Use bool for booleans.
1324 * cmds.c (move_point, Fself_insert_command):
1325 * coding.h (struct composition status, struct coding_system):
1326 * coding.c (detect_coding_utf_8, encode_coding_utf_8)
1327 (detect_coding_utf_16, encode_coding_utf_16, detect_coding_emacs_mule)
1328 (emacs_mule_char, decode_coding_emacs_mule)

1346 Use bool for booleans.
1347 * coding.h, lisp.h: Reflect above API changes.
1348 * coding.c: Remove unnecessary static function decls.
1349 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
1350 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
1351 not a boolean 'int', since callers never look at the return value.
1352 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
1353 * coding.h (decoding_buffer_size, encoding_buffer_size)
1354 (emacs_mule_string_char): Remove unused extern decls.
1355 (struct iso_2022_spec, struct coding_system):
1356 Use 'unsigned int : 1' for boolean fields, since there's more than one.
1357 (struct emacs_mule_spec): Remove unused field 'full_support'.
1358 All initializations removed.
1359 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
1360
1361 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
1362
1363 Fix spare memory change (Bug#12286).
1364 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
1365 (valid_lisp_object_p): Likewise.
1366
1367 2012-08-27 Martin Rudalics <rudalics@gmx.at>
1368
1369 * window.c (Fset_window_configuration): Record any window's old
1370 buffer if it's replaced (see Bug#8789). If the new current
1371 buffer doesn't appear in the selected window, go to its old
1372 point (Bug#12208).
1373
1374 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
1375
1376 Special MEM_TYPE_SPARE to denote reserved memory.
1377 * alloc.c (enum mem_type): New memory type.
1378 (refill_memory_reserve): Use new type for spare memory.
1379 This prevents live_cons_p and live_string_p from incorrect
1380 detection of uninitialized objects from spare memory as live.
1381
1382 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
1383
1384 Spelling fixes.
1385 * Makefile.in (.PHONY): versioclean -> versionclean.
1386
1387 Remove unused external symbols.
1388 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
1389 * window.c (Qwindow_valid_p, decode_valid_window):
1390 Now static, not extern.
1391 * data.c (Qinterval): Remove; unused.
1392 (syms_of_data): Do not define 'interval'.
1393 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
1394 * window.h (decode_valid_window):
1395 Remove decls.
1396
1397 * character.c, charset.c, chartab.c: Use bool for booleans.
1398 * character.c (lisp_string_width, string_count_byte8)
1399 (string_escape_byte8):
1400 * charset.c (charset_map_loaded, load_charset_map, read_hex):
1401 (load_charset_map_from_file, map_charset_chars)
1402 (Fdefine_charset_internal, define_charset_internal)
1403 (Fdeclare_equiv_charset, find_charsets_in_text)
1404 (Ffind_charset_region, char_charset, Fiso_charset):
1405 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
1406 (sub_char_table_set, sub_char_table_set_range)
1407 (char_table_set_range, optimize_sub_char_table)
1408 (map_sub_char_table):
1409 Use bool for boolean.
1410 * character.c (str_to_unibyte): Omit last boolean argument; it was
1411 always 0. All callers changed.
1412 * character.h, charset.h: Adjust to match previous changes.
1413 * character.h (char_printable_p): Remove decl of nonexistent function.
1414 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
1415 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
1416 are all boolean, so make them single-bit bitfields.
1417
1418 * lisp.h (ASET): Remove attempt to detect side effects.
1419 It was meant to be temporary and it often doesn't work,
1420 because when IDX has side effects the behavior of IDX==IDX
1421 is undefined. See Stefan Monnier in
1422 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
1423
1424 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
1425
1426 * lisp.h (functionp): New function (extracted from Ffunctionp).
1427 (FUNCTIONP): Use it.
1428 * eval.c (Ffunctionp): Use it.
1429
1430 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1431
1432 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
1433 as that's faster and simpler than static storage. Don't bother
1434 with the g_main_context_query overhead if g_main_context_pending
1435 says no events are pending.
1436 (gfds, gfds_size): Remove these static vars.
1437 (xgselect_initialize): Remove; no longer needed.
1438 All uses and decls removed.
1439
1440 * emacs.c (fatal_error_signal_hook): Remove.
1441 All uses removed. This leftover from old code was always 0.
1442
1443 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
1444 * casefiddle.c (casify_object, casify_region):
1445 * casetab.c (set_case_table):
1446 * category.c, category.h (word_boundary_p):
1447 * category.h (CHAR_HAS_CATEGORY):
1448 Use bool for booleans, instead of int.
1449
1450 2012-08-25 Eli Zaretskii <eliz@gnu.org>
1451
1452 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
1453
1454 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
1455
1456 On assertion failure, print backtrace if available.
1457 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
1458 (die) [ENABLE_CHECKING]: Print a backtrace if available.
1459 * Makefile.in (LIB_EXECINFO): New macro.
1460 (LIBES): Use it.
1461
1462 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
1463 * bytecode.c (exec_byte_code):
1464 * callint.c (check_mark, Fcall_interactively):
1465 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
1466 (getenv_internal, sync_process_alive, call_process_exited):
1467 * lisp.h (USE_SAFE_ALLOCA):
1468 Use bool for booleans, instead of int.
1469 * lisp.h, process.h: Adjust prototypes to match above changes.
1470 * callint.c (Fcall_interactively): Don't assume the mark's
1471 offset fits in 'int'.
1472
1473 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
1474
1475 * buffer.c, buffer.h: Use bool for boolean.
1476 * buffer.c (reset_buffer_local_variables)
1477 (buffer_lisp_local_variables, Fset_buffer_modified_p)
1478 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
1479 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
1480 (overlay_touches_p, overlay_strings, Foverlay_put)
1481 (report_overlay_modification, call_overlay_mod_hooks):
1482 (mmap_enlarge, mmap_set_vars):
1483 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
1484 Use bool for booleans, instead of int.
1485 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
1486 since the 1-or-0 return value is always ignored anyway.
1487 (mmap_initialized_p):
1488 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
1489 * buffer.h, lisp.h: Adjust prototypes to match above changes.
1490
1491 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1492
1493 * bidi.c: Use bool for boolean.
1494 This is a bit more readable, and makes the text segment of bidi.o
1495 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
1496 Presumably it's faster too.
1497 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
1498 Now bool.
1499 (bidi_cache_find_level_change, bidi_cache_iterator_state)
1500 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
1501 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
1502 (bidi_explicit_dir_char, bidi_level_of_next_char)
1503 (bidi_find_other_level_edge, bidi_move_to_visually_next):
1504 Use bool for booleans, instead of int.
1505 * dispextern.h (bidi_init_it, bidi_paragraph_init)
1506 (bidi_unshelve_cache): Adjust decls to match code.
1507
1508 2012-08-23 Martin Rudalics <rudalics@gmx.at>
1509
1510 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
1511 argument.
1512
1513 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
1514
1515 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
1516 * atimer.h: Include <stdbool.h>.
1517
1518 2012-08-22 Dan Nicolaescu <dann@gnu.org>
1519
1520 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
1521 compile time tests instead of run time tests on systems that do
1522 not use them.
1523 (FRAME_MAC_P): Remove leftover from deleted code.
1524 * frame.c (syms_of_frame): Remove leftover from deleted code.
1525
1526 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
1527
1528 * nsterm.m (insertText:): Don't clear modifiers if code is space.
1529
1530 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
1531
1532 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
1533 Otherwise, the compiler complains about (A?B:C) where B is void
1534 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
1535 (fontset_add): Return void, for FONTSET_ADD.
1536
1537 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1538
1539 * alloc.c: Use bool for booleans.
1540 (gc_in_progress, abort_on_gc)
1541 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1542 (dont_register_blocks) [GC_MALLOC_CHECK]:
1543 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
1544 (check_string_bytes, make_specified_string, memory_full)
1545 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
1546 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
1547 (mark_stack, valid_pointer_p, make_pure_string)
1548 (Fgarbage_collect, survives_gc_p, gc_sweep):
1549 Use bool for booleans, instead of int.
1550 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
1551 Remove unused local.
1552 * alloc.c (PURE_POINTER_P):
1553 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
1554 * editfns.c (Fformat):
1555 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
1556 (Fdo_auto_save):
1557 * fns.c (sweep_weak_table):
1558 * lisp.h (suppress_checking, push_message, survives_gc_p)
1559 (make_pure_string, gc_in_progress, abort_on_gc):
1560 * lread.c (readchar, read1):
1561 * print.c (Fprin1_to_string):
1562 * xdisp.c (push_message):
1563 Use bool for booleans affected directly or indirectly by
1564 alloc.c's changes.
1565
1566 Make recently-introduced setters macros.
1567 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
1568 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
1569 (set_fontset_default, set_fontset_fallback): Rename from their
1570 upper-case counterparts, and make them functions rather than macros.
1571 This is more consistent with the other recently-introduced setters.
1572 These don't need to be inline, since they're local.
1573
1574 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
1575
1576 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
1577 the loop (Bug#12247).
1578
1579 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1580
1581 * lisp.h (vcopy): Use memcpy rather than our own loop.
1582 This fixes a performance regression introduced by the recent
1583 addition of vcopy. This means 'vcopy' will need to be modified
1584 for a copying collector, but that's OK. Also, tighten the
1585 checking in the assertion.
1586
1587 2012-08-21 Eli Zaretskii <eliz@gnu.org>
1588
1589 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
1590 components for RTL text (Bug#11860). Adjust X-OFFSET of each
1591 non-base glyph for the width of the base character, according to
1592 what x_draw_composite_glyph_string_foreground expects.
1593 Generate WADJUST value according to composition_gstring_width's
1594 expectations, to produce correct width of the composed character.
1595 Reverse the sign of the DU offset produced by ScriptPlace.
1596
1597 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
1598
1599 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
1600
1601 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1602
1603 Avoid direct writes to contents member of struct Lisp_Vector.

1611 * xface.c (Finternal_copy_lisp_face): Use vcopy.
1612 (Finternal_merge_in_global_face): Use ASET and vcopy.
1613 * xfont.c (xfont_list_pattern): Likewise.
1614
1615 2012-08-21 Martin Rudalics <rudalics@gmx.at>
1616
1617 * window.c (Fwindow_point): For the selected window always return
1618 the position of its buffer's point.
1619 (Fset_window_point): For the selected window always go in its
1620 buffer to the specified position.
1621
1622 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
1623
1624 Setter macros for fontsets.
1625 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
1626 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
1627 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
1628 Adjust users.
1629
1630 2012-08-20 Glenn Morris <rgm@gnu.org>
1631
1632 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
1633 Don't assume that `ln -f' works.
1634
1635 2012-08-20 Eli Zaretskii <eliz@gnu.org>
1636
1637 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
1638 and later about non-assignments with no effect. See discussion at
1639 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
1640 details.
1641
1642 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1643
1644 Inline setter functions for Lisp_Objects slots of struct specbinding.
1645 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
1646 Adjust users.
1647
1648 2012-08-20 Martin Rudalics <rudalics@gmx.at>
1649
1650 * window.c (select_window): Always make selected window's buffer
1651 current.
1652
1653 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1654
1655 Use AREF and ASET for docstrings of category tables.
1656 * category.h (CATEGORY_DOCSTRING): Use AREF.
1657 (SET_CATEGORY_DOCSTRING): Use ASET.
1658 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
1659
1660 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
1661
1662 Inline setter functions for hash table members.
1663 * lisp.h (set_hash_key, set_hash_value, set_hash_next)

1680
1681 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
1682
1683 Rely on <config.h> + <unistd.h> to declare 'environ',
1684 as gnulib does this if the system doesn't.
1685 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
1686 Remove declaration. MS-Windows declares it on stdlib.h which is
1687 included by conf_post.h.
1688 * emacs.c (environ) [DOUG_LEA_MALLOC]:
1689 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.

1696 and avoid a gcc -Wmaybe-uninitialized diagnostic.
1697
1698 2012-08-19 Chong Yidong <cyd@gnu.org>
1699
1700 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string

1720 * chartab.c, lisp.h (char_table_set, char_table_set_range):
1721 Return void, not Lisp_Object. Otherwise, the compiler
1722 complains about (A?B:C) where B is void and C is Lisp_Object
1723 when compiling CHAR_TABLE_SET, due to the recent change to
1724 the API of sub_char_table_set_contents.

1884 The old version was confusing because it used the same name
1885 'parent' for two different things.

2497
2498 Fix replacement typo.
2499 * window.c (replace_window): Set root_window instead of

2557 * w32.c (init_environment): Change the default values of many
2558 environment variables in dflt_envvars[] to NULL, to avoid pushing
2559 them into environment when they were not already defined.
2560 Remove the code that deletes site-lisp subdirectories from the default
2561 value of EMACSLOADPATH, as it is no longer needed.
2562 (check_windows_init_file): Now external, not static.
2563 Use Vload_path as is, without adding anything, as this function is now
2564 called when Vload_path is already set up.
2565
2566 * w32.h (check_windows_init_file): Add prototype.
2567
2568 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
2569 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
2570 compatibility with Posix platforms.
2571 (main): Move the call to check_windows_init_file to here from
2572 w32.c.
2573 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
2574 any, in the DEFALT argument into the root of the Emacs build or
2575 installation tree, as appropriate.
2576
2577 * callproc.c (init_callproc_1): Call decode_env_path instead of

2583
2584 * msdos.c (dos_set_window_size, IT_update_begin)
2585 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR

2593
2594 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
2595
2596 Remove unnecessary casts involving pointers.
2597 These casts are no longer needed now that we assume C89 or later,
2598 since they involve casting to or from void *.
2599 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
2600 (make_pure_float, make_pure_vector):
2601 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

2610 (x_get_window_property, x_get_window_property_as_lisp_data):
2611 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
2612 Remove unnecessary pointer casts.
2613 * alloc.c (record_xmalloc): New function.
2614 * lisp.h (record_xmalloc): New decl.
2615 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
2616 more like a function. This is because the pointer cast is not
2617 needed. All uses changed.
2618 * print.c (print_string, print_error_message): Avoid length recalc.
2619
2620 Improve fix for macroexp crash with debugging (Bug#12118).
2621 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
2622 ARRAY_MARK_FLAG when checking subscripts, because ASET is
2623 not supposed to be invoked from the garbage collector.
2624 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
2625 (gc_aset): New function, which is like ASET but can be
2626 used in the garbage collector.
2627 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
2628 (set_hash_index): Use it instead of ASET.

2644 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
2645 New functions.
2646 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
2647 in the argument file name.
2648 (sys_access): Call unc_volume_file_attributes only if
2649 GetFileAttributes fails with network-related error codes.
2650 (sys_rename): Diagnose renaming of a symlink when the user doesn't
2651 have the required privileges.
2652 (get_file_security_desc_by_name): Rename from
2653 get_file_security_desc.
2654 (stat_worker): New function, with most of the guts of 'stat', and
2655 with addition of handling of symlinks and support for 'lstat'.
2656 If possible, get file's attributes and security information by
2657 handle, not by name. Produce S_IFLNK bit for symlinks, when
2658 called from 'lstat'.
2659 (stat, lstat): New functions, call 'stat_worker'.
2660 (symlink, readlink, careadlinkat): Rewritten to create and resolve
2661 symlinks when the underlying filesystem supports them.
2662

2664
2665 Fix macroexp crash on Windows with debugging (Bug#12118).
2666 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
2667 checking subscripts; problem introduced with the recent
2668 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
2669 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
2670 since it's used in non-static inline functions now.
2671
2672 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
2673 Don't assume buffer size fits in 'int'. Remove unused local.

2687 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
2688 * alloc.c (LISP_INLINE):

2690 * category.c (CATEGORY_INLINE):
2691 * character.c (CHARACTER_INLINE):
2692 * charset.c (CHARSET_INLINE):
2693 * composite.c (COMPOSITE_INLINE):
2694 * dispnew.c (DISPEXTERN_INLINE):
2695 * sysdep.c (SYSTIME_INLINE):
2696 Define to EXTERN_INLINE, so that the corresponding functions
2697 are compiled into code.

2699 (INLINE_HEADER_END): New macros.
2700 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

2721
2722 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
2723
2724 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
2725 This how ASET and AREF are supposed to work, and makes
2726 it easier to think about future improvements. See
2727 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.

3120 * w32inevt.h: Declare w32_console_unicode_input.
3121
3122 * xdisp.c (init_iterator): Don't reference tip_frame in a build

3125 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
3126
3127 Adjust GDB to reflect pvec_type changes (Bug#12036).

3141 list.
3142

3147
3148 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3149

3164 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different

3166 complains about the types in the unevaluated arm when the argument
3167 is an integer literal.
3168 (xgetint): Simplify expression.
3169 * alloc.c (gdb_make_enums_visible): New constant. This ports to

3172 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
3173 needed now that we have gdb_make_enums_visible.

3176 New enum types, packaging up enums that need to be exported to GDB.

3211 * editfns.c (save_excursion_save, save_excursion_restore):
3212 Reimplement to use struct Lisp_Excursion. Add comments.
3213
3214 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
3215
3216 Fix export of symbols to GDB (Bug#12036).
3217 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
3218 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
3219 emacs.c, as this is a more-suitable home. Had this been done earlier
3220 the fix for 12036 would have avoided some of the problems noted in
3221 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
3222 would have been more obvious.
3223 * emacs.c: Do not include <verify.h>; no longer needed.
3224 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)

3232 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
3233 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
3234 not be usable in #if. This simplifies things.
3235
3236 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
3237
3238 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

3240 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
3241
3242 Simplify export of symbols to GDB (Bug#12036).
3243 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
3244 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
3245 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
3246 Adjust to changes in lisp.h and emacs.c, by using
3247 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
3248 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
3249 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
3250 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
3251 instead of gdb_valbits.
3252 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
3253 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
3254 instead of gdb_array_mark_flag.

4077 * s/hpux10-20.h (HAVE_PERROR): Remove.
4078 * sysdep.c (perror) [HPUX && !HAVE_PERROR]:
4079 Remove dummy definition, as this problem was obsolete long ago.

4081 Assume strerror.
4082 * sysdep.c (strerror) [!HAVE_STRERROR && !WINDOWSNT]: Remove.
4083
4084 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>

4091 Adjust prototypes.
4092 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
4093 Change to return ptrdiff_t.
4094 (xfont_list_pattern, xfont_match): Use length returned by
4095 xfont_decode_coding_xlfd.

4101 Move DONT_REOPEN_PTY to configure.
4102
4103 * sound.c (DEFAULT_SOUND_DEVICE) [!WINDOWSNT]:

4105
4106 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
4107
4108 Remove "#define unix" that is no longer needed (Bug#11905).
4109 * s/aix4-2.h (unix): Remove; no longer needed.
4110
4111 EMACS_TIME simplification (Bug#11875).
4112 This replaces macros (which typically do not work in GDB)
4113 with functions, typedefs and enums, making the code easier to debug.
4114 The functional style also makes code easier to read and maintain.
4115 * systime.h: Include <sys/time.h> on all hosts, not just if
4116 WINDOWSNT, since 'struct timeval' is needed in general.
4117 (EMACS_TIME): Now a typedef, not a macro.
4118 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
4119 not macros.
4120 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
4121 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)

4124 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
4125 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
4126 which are not functions. All uses rewritten to use:
4127 (make_emacs_time): New function.
4128 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
4129 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
4130 not functions. All uses rewritten to use the following, respectively:
4131 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
4132 (add_emacs_time, sub_emacs_time): New functions.
4133 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
4134 * fileio.c (Fcopy_file):
4135 * xterm.c (XTflash): Get the current time closer to when it's used.
4136 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
4137
4138 * bytecode.c (targets): Suppress -Woverride-init warnings.
4139

4142 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
4143 * frame.c (Fmake_terminal_frame):
4144 * gtkutil.c (get_utf8_string):
4145 * lread.c (openp):
4146 * nsmenu.m (ns_update_menubar):
4147 * regex.c (regerror):
4148 Prefer memcpy to strncpy and strncat when either will do.
4149 * fileio.c (Fsubstitute_in_file_name):
4150 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
4151 (menu_separator_name_p):
4152 * nsmenu.m (ns_update_menubar):
4153 Prefer memcmp to strncmp when either will do.
4154 * nsterm.m: Include <ftoastr.h>.
4155 (ns_get_color):
4156 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
4157 Prefer snprintf to strncpy.
4158 * nsterm.m (ns_term_init):
4159 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
4160 * nsterm.m (ns_term_init):
4161 Avoid the need for strncpy, by using build_string or
4162 make_unibyte_string directly. Use dtoastr, not snprintf.
4163 * process.c (Fmake_network_process): Diagnose service names that
4164 are too long, rather than silently truncating them or creating
4165 non-null-terminated names.
4166 (Fnetwork_interface_info): Likewise, for interface names.
4167 * sysdep.c (system_process_attributes) [GNU_LINUX]:
4168 Prefer sprintf to strncat.
4169 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
4170 Prefer vsnprintf to vsprintf + strncpy.
4171
4172 2012-07-10 Glenn Morris <rgm@gnu.org>
4173
4174 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
4175 Clarify fallback case.
4176
4177 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4178
4179 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
4180 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
4181 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
4182 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
4183 where argument type is known to be a Lisp_Cons.
4184
4185 2012-07-10 Tom Tromey <tromey@redhat.com>
4186
4187 * bytecode.c (BYTE_CODE_THREADED): New macro.
4188 (BYTE_CODES): New macro. Replaces all old byte-code defines.
4189 (enum byte_code_op): New type.
4190 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
4191 (exec_byte_code): Use them. Use token threading when applicable.
4192
4193 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4194
4195 Optimize pure C strings initialization.
4196 * lisp.h (make_pure_string): Fix prototype.
4197 (build_pure_c_string): New function, defined as static inline. This
4198 provides a better opportunity to optimize away calls to strlen when
4199 the function is called with compile-time constant argument.
4200 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
4201 argument, adjust users accordingly. Use build_pure_c_string where
4202 appropriate.
4203 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
4204 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
4205 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
4206
4207 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4208
4209 Avoid calls to strlen in miscellaneous functions.
4210 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
4211 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
4212 * lread.c (openp): Likewise.
4213
4214 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
4215
4216 Avoid calls to strlen in path processing functions.
4217 * fileio.c (file_name_as_directory): Add comment. Change to add
4218 srclen argument and return the length of result. Adjust users
4219 accordingly.
4220 (directory_file_name): Fix comment. Change to add srclen argument,
4221 swap 1st and 2nd arguments to obey the common convention.
4222 Adjust users accordingly.
4223 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
4224
4225 2012-07-10 Glenn Morris <rgm@gnu.org>
4226
4227 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
4228 Move PENDING_OUTPUT_COUNT definition to configure.
4229
4230 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
4231 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
4232 * s/gnu.h (DATA_START): Move definitions to configure.
4233
4234 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
4235 We include usg5-4-common.h, which defines them both.
4236
4237 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
4238 O_RDONLY already includes it).
4239
4240 Stop ns builds setting the EMACSLOADPATH environment variable.
4241 * nsterm.m (ns_load_path): Rename from ns_init_paths.
4242 Now it does not set EMACSLOADPATH, just returns the load-path string.
4243 * nsterm.h: Update accordingly.
4244 * lread.c [HAVE_NS]: Include nsterm.h.
4245 (init_lread) [HAVE_NS]: Use ns_load_path.
4246 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
4247
4248 2012-07-09 Glenn Morris <rgm@gnu.org>
4249
4250 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
4251 since the included bsd-common.h does so.
4252
4253 Stop ns builds setting the EMACSPATH environment variable.
4254 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
4255 (ns_init_paths): Do not set EMACSPATH.
4256 * nsterm.h (ns_exec_path): Add it.
4257 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
4258 Use ns_exec_path.
4259
4260 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
4261
4262 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
4263
4264 * process.c (wait_reading_process_output): 'waitchannels' was unset
4265 when read_kbd || !NILP (wait_for_cell); fix this.
4266
4267 Add GCC-style 'const' attribute to functions that can use it.
4268 * character.h (char_resolve_modifier_mask):
4269 * keyboard.h (make_ctrl_char):
4270 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
4271 (init_character_once, next_almost_prime, init_fns, init_image)
4272 (flush_pending_output, init_sound):
4273 * mem-limits.h (start_of_data):
4274 * menu.h (finish_menu_items):
4275 Add ATTRIBUTE_CONST.
4276 * emacs.c (DEFINE_DUMMY_FUNCTION):
4277 Declare the dummy function with ATTRIBUTE_CONST.
4278 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
4279 Add decls with ATTRIBUTE_CONST.
4280
4281 Minor improvements to make_formatted_string.
4282 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
4283 where int is good enough, as vsprintf returns an int.
4284 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
4285
4286 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4287
4288 Use make_formatted_string to avoid double length calculation.
4289 * lisp.h (make_formatted_string): New prototype.
4290 * alloc.c (make_formatted_string): New function.
4291 * buffer.c (Fgenerate_new_buffer_name): Use it.

4303
4304 2012-07-09 Glenn Morris <rgm@gnu.org>
4305

4309 * nsterm.h (ns_etc_directory): Add it.
4310 * callproc.c [HAVE_NS]: Include nsterm.h.
4311 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
4312
4313 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
4314
4315 Move marker debugging code under MARKER_DEBUG.
4316 * marker.c (MARKER_DEBUG): Move marker debugging code under
4317 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
4318 for bootstrap with --enable-checking (~3x slowdown reported
4319 by Juanma Barranquero <lekktu@gmail.com>).
4320 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
4321
4322 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
4323
4324 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
4325 See <http://bugs.gnu.org/11825#29>.
4326
4327 2012-07-08 Eli Zaretskii <eliz@gnu.org>
4328
4329 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
4330 has no font, use the frame's font. (Bug#11813)
4331 (display_line): Add commentary about displaying truncation glyphs
4332 on GUI frames.
4333 (produce_special_glyphs): Move here from term.c.
4334
4335 * term.c (produce_special_glyphs): Move to xdisp.c.
4336
4337 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
4338 section.
4339
4340 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
4341
4342 * xdisp.c (display_line): Avoid warning about implicit declaration
4343 of FRAME_FONT.
4344
4345 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
4346
4347 * lisp.h: Remove empty conditional.
4348
4349 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4350
4351 * lread.c (load_path_check): Now static.
4352
4353 Fix some minor --with-ns problems found by static checking.
4354 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
4355 (x_set_font) [!HAVE_X_WINDOWS]:
4356 * image.c (xpm_load_image) [HAVE_NS]:
4357 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
4358 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
4359 Remove unused local.
4360 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
4361 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
4362 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
4363 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
4364 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
4365 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
4366 Fix pointer signedness problem.
4367 * xfaces.c (FRAME_X_FONT_TABLE):
4368 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
4369
4370 2012-07-07 Glenn Morris <rgm@gnu.org>
4371
4372 * lread.c (load_path_check): New function, split from init_lread.
4373 (init_lread): Reorganize. Motivation:
4374 If EMACSLOADPATH is set, check/warn about that rather than the
4375 defaults, which we are not going to use. Hence we can remove
4376 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
4377 Don't warn if site-lisp directories are missing.
4378 If not installed, start from a blank load-path, since
4379 PATH_LOADSEARCH refers to the eventual installation directories.
4380
4381 2012-07-07 Eli Zaretskii <eliz@gnu.org>
4382
4383 Support truncation and continuation glyphs on GUI frames, when
4384 fringes are disabled. (Bug#11832)
4385 * xdisp.c (init_iterator): Get dimensions of truncation and
4386 continuation glyphs even if on GUI frames.
4387 Adjust it->last_visible_x on GUI frames when the left or right fringes,
4388 or both, are absent.
4389 (start_display, move_it_in_display_line_to): Handle the case of a
4390 GUI frame without a fringe to display continuation or truncation
4391 glyphs.
4392 (insert_left_trunc_glyphs): Support GUI frames: make sure
4393 truncation glyphs overwrite enough glyphs from the current line to
4394 have sufficient space in pixels.
4395 (display_line): Support truncation and continuation glyphs on GUI
4396 frames. If some spare pixels are left on the line after inserting
4397 the truncation glyphs, fill that space with a stretch glyph of a
4398 suitably computed width.
4399
4400 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
4401 produce_glyphs, to support GUI sessions.
4402
4403 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
4404
4405 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
4406
4407 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
4408
4409 Do not require float-time's arg to fit in time_t (Bug#11825).
4410 This works better on hosts where time_t is unsigned, and where
4411 float-time is applied to the (negative) difference between two times.
4412 * editfns.c (decode_time_components): Last arg is now double *,
4413 not int *, and means to store all the result as a double, without
4414 worrying about whether the seconds part fits in time_t.
4415 All callers changed.
4416 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
4417 All callers changed.
4418 (Ffloat_time): Do not fail merely because the specified time falls
4419 outside of time_t range.
4420
4421 2012-07-07 Glenn Morris <rgm@gnu.org>
4422
4423 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
4424 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

4426
4427 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
4428
4429 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
4430 Update dependencies.
4431
4432 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
4433
4434 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4435
4436 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
4437 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
4438 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
4439 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
4440 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
4441 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
4442
4443 * xfont.c (compare_font_names): Redo to omit the need for casts.
4444
4445 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
4446
4447 * xfns.c (Fx_change_window_property): Doc fix.
4448 * w32fns.c (Fx_change_window_property): Doc fix.
4449
4450 * w32fns.c (Fx_window_property): Accept the same arguments as the
4451 X Windows version. Doc fix.
4452 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
4453
4454 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
4455 Eli Zaretskii <eliz@gnu.org>
4456
4457 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
4458 Windows-specific code from nt/config.nt moved here.
4459 Obsolete settings removed.
4460
4461 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4462
4463 * process.c: Avoid unnecessary calls to gettime.
4464 (wait_reading_process_output): Don't get the time of day
4465 when gobbling data immediately and not waiting, as there's no need
4466 for it in that case. This removes a FIXME.
4467
4468 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
4469
4470 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
4471 is defined (Bug#11768).
4472
4473 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4474
4475 Fix marker debugging code.
4476 * marker.c (byte_char_debug_check): Do not perform the check
4477 if buffer is not multibyte.
4478 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4479 Call byte_char_debug_check with correct arguments.
4480
4481 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4482
4483 Compile marker debugging code only if ENABLE_CHECKING is defined.
4484 * marker.c (byte_char_debug_check, count_markers):
4485 Use only if ENABLE_CHECKING is defined.
4486 (byte_debug_flag): Remove.
4487 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
4488 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
4489
4490 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4491
4492 Avoid code repetition in marker-related functions.
4493 * marker.c (attach_marker): New function.
4494 (Fset_marker, set_marker_restricted, set_marker_both)
4495 (set_marker_restricted_both): Use it.
4496 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
4497 Consistently rename charno to charpos.
4498 (marker_position): Add eassert.
4499 (marker_byte_position): Convert to eassert.
4500
4501 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
4502
4503 Simplify list operations in unchain_overlay and unchain_marker.

4523 to avoid redundant calls to unchain_overlay.
4524 * buffer.c (drop_overlay): New function.
4525 (delete_all_overlays, Fdelete_overlay): Use it.
4526 * minibuf.c (get_minibuffer): Fix comment.
4527
4528 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
4529
4530 Port to OpenBSD 5.1 amd64.
4531 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
4532 This is needed for OpenBSD, and should be harmless on all BSD systems.
4533 Also, include <sys/sysctl.h>, as it should be available on all
4534 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
4535 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
4536 use p_pid member, not kp_proc.pid.
4537
4538 2012-07-06 Glenn Morris <rgm@gnu.org>
4539
4540 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
4541
4542 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4543
4544 More xmalloc and related cleanup.
4545 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

4553 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
4554 * xterm.c:
4555 Omit needless casts involving void * pointers and allocation.
4556 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
4557 as the former is more robust if P's type is changed.
4558 Prefer xzalloc to xmalloc + memset 0.
4559 Simplify malloc-or-realloc to realloc.
4560 Don't worry about xmalloc returning a null pointer.

4567 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4568
4569 * xdisp.c (display_line): Fix horizontal pixel coordinates when
4570 hscroll is larger than the line width. Fixes long and futile
4571 looping inside extend_face_to_end_of_line (on a TTY) producing
4572 glyphs that are not needed and thrown away.
4573
4574 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
4575
4576 * marker.c (set_marker_restricted_both): Simplify by using
4577 clip_to_bounds.
4578
4579 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
4580
4581 * editfns.c (region_limit): Simplify by using clip_to_bounds.
4582
4583 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
4584
4585 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
4586 not defined (Bug#11768).
4587 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
4588 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
4589 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
4590 followed by gtk_box_set_homogeneous (Bug#11768).
4591 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
4592 (update_theme_scrollbar_width, xg_create_scroll_bar):
4593 Use gtk_scrollbar_new (Bug#11768).
4594 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
4595 (is_box_type): New function (Bug#11768).
4596 (xg_tool_item_stale_p): Call is_box_type.
4597 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
4598 with default display (Bug#11768).
4599
4600 2012-07-05 Eli Zaretskii <eliz@gnu.org>
4601
4602 * xdisp.c (window_hscroll_limited): New function.
4603 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
4604 coordinates when window's hscroll is set to insanely large
4605 values. (Bug#11857)
4606

4671 Problem reported by Troels Nielsen in
4672 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
4673
4674 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4675
4676 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
4677 This should be fixed in a better way; see Eli Zaretskii in
4678 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
4679 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
4680
4681 * fileio.c (time_error_value): Rename from special_mtime.
4682 The old name's problems were noted by Eli Zaretskii in
4683 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
4684
4685 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
4686 This variable's comment says Emacs needs at least one GDB-visible
4687 symbol of type enum pvec_type, to work around GDB problems.
4688 The symbol's value doesn't matter.
4689
4690 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
4691 that causes compilation to fail on pre-C99 compilers.

4708 (PSEUDOVECTOR_SIZE_BITS): New constant.
4709 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
4710 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
4711 change in pvec_type.

4718 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
4719 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
4720 (sweep_vectors): Use it. Use local var `total_bytes' instead of
4721 abusing vector->header.next.nbytes.
4722 (live_vector_p): Use PVEC_TYPE.
4723 (mark_object): Adapt code to extract pvectype. Use switch.
4724
4725 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4726
4727 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
4728 Tighten new eassert a bit.

4730 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
4731
4732 Fix compilation with --enable-gcc-warnings and -O1
4733 optimization level.
4734 * doprnt.c (doprnt): Change type of tem to int, initialize
4735 to avoid compiler warning. Add eassert.
4736 * search.c (simple_search): Initialize match_byte to avoid
4737 compiler warning. Add eassert.
4738
4739 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4740
4741 Avoid weird behavior with large horizontal scrolls.
4742 Without this change, for example, large hscroll values would
4743 mess up Emacs's display on Fedora 15 x86, presumably due to
4744 overflows in int calculations in the display code.
4745 Also, if buffers had long lines, Emacs would freeze.
4746 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
4747 (set_window_hscroll): New function, containing the old guts of
4748 Fset_window_hscroll. Return the clipped value.
4749 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
4750 This avoids the need to check against PTRDIFF_MAX.
4751
4752 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
4753
4754 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

4757
4758 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
4759
4760 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
4761 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
4762 since GCC 4.4.6 issues a bogus warning for them.
4763
4764 Fix bugs in file timestamp newness comparisons.
4765 * fileio.c (Ffile_newer_than_file_p):
4766 * lread.c (Fload): Use full timestamp resolution of files,
4767 not just the 1-second resolution, so that files that are only
4768 slightly newer still count as newer.
4769 * fileio.c (Ffile_newer_than_file_p): Don't assume file
4770 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
4771
4772 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
4773
4774 * fileio.c: Improve handling of file time marker. (Bug#11852)

4783
4784 2012-07-03 Glenn Morris <rgm@gnu.org>
4785
4786 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
4787 and did not make it into globals.h).
4788
4789 2012-07-03 Tom Tromey <tromey@redhat.com>

4834
4835 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
4836 values which aren't power of 2.
4837 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
4838 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
4839 accordingly.

4861
4862 Cleanup basic buffer management.
4863 * buffer.h (struct buffer): Change layout to use generic vector

4878 and related comments.
4879
4880 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
4881
4882 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
4883 wrapper that is not needed because the wrapped code is a no-op (zero
4884 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
4885 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
4886
4887 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
4888
4889 * alloc.c (mark_buffer): Simplify. Remove prototype.
4890 (mark_object): Add comment. Reorganize marking of vector-like
4891 objects. Use CHECK_LIVE for all vector-like objects except buffers
4892 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
4893 Avoid redundant calls to mark_vectorlike for bool vectors.

4898
4899 * epaths.in (PATH_SITELOADSEARCH): New.

4901 This is rather than relying on --enable-locallisppath elements
4902 having "site-lisp" in their names. (Bug#10208#25, 11658)
4903
4904 2012-06-30 Eli Zaretskii <eliz@gnu.org>

4907
4908 * w32.c (emacs_gnutls_pull): Call select with one more argument.
4909
4910 * sysselect.h [DOS_NT]: Don't include sys/select.h.
4911 (pselect) [!MS_DOS]: Redirect to sys_select.
4912
4913 * sysdep.c: Don't include dos.h and dosfns.h.
4914
4915 * process.c (sys_select):
4916 * msdos.c (sys_select): Accept one more argument and ignore it.
4917
4918 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
4919 adapt data types and code to that.
4920
4921 * dosfns.c:
4922 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
4923 which clashes with the gnulib function of the same name.
4924
4925 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
4926
4927 * font.c (font_style_to_value, font_style_symbolic)

4938 * xdisp.c (try_window_id): Undo last change.
4939
4940 * w32.c (getwd): Adjust commentary about startup_dir.
4941 (init_environment): Always call sys_access, even in non-MSVC
4942 builds. Don't chdir to the directory of the Emacs executable.
4943 This undoes code from 1997 which was justified by the need to
4944 "avoid conflicts when removing and renaming directories". But its
4945 downside was that every relative file name was being interpreted
4946 relative to the directory of the Emacs executable, which can never
4947 be TRT. In particular, it broke sys_access when called with
4948 relative file names.
4949 (sys_access): Map GetLastError to errno.

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

5156 Use sprintf or float_to_string result to avoid need to call strlen.
5157 * data.c (Fnumber_to_string):

5159 * lisp.h, print.c (float_to_string): Now returns int length.
5160 * term.c (produce_glyphless_glyph):
5161 Use sprintf result rather than recomputing it.

5193
5194 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>

5200
5201 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string

5334 Support higher-resolution time stamps (Bug#9000).
5335 The time stamps are only nanosecond-resolution at the C level,
5336 since that's the best that any real-world system supports now.
5337 But they are picosecond-resolution at the Lisp level, as that's
5338 easy, and leaves room for future OS improvements.
5339
5340 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
5341 (LIBES): Use it.
5342
5343 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
5344 Don't get current time unless it's needed.
5345
5346 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
5347 now provides it if it's absent.
5348 (start_atimer): Port to higher-res time stamps.
5349 Check for time stamp overflow. Don't get current time more
5350 often than is needed.
5351
5352 * buffer.h (struct buffer): Buffer modtime now has high resolution.
5353 Include systime.h, not time.h.
5354 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
5355
5356 * dired.c: Include stat-time.h.
5357 (Ffile-attributes): File times now have higher resolution.
5358
5359 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
5360 (struct image): Timestamp now has higher resolution.
5361
5362 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
5363 has at least microseconds now. All uses removed.
5364 (update_frame, update_single_window, update_window, update_frame_1)
5365 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
5366 (duration_to_sec_usec): Remove; no longer needed.
5367

5369 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
5370 (float-time, Fformat_time_string, Fcurrent_time_string)
5371 (Fcurrent_time_zone): Accept and generate higher-resolution
5372 time stamps.
5373 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
5374 (decode_time_components, lisp_seconds_argument): New functions.
5375 (make_time): Now static.
5376 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
5377 Report an error if the time is invalid, rather than having the caller
5378 do that.
5379
5380 * fileio.c: Include <stat-time.h>
5381 (Fcopy_file): Copy higher-resolution time stamps.
5382 Prefer to set the time stamp via a file descriptor if that works.
5383 (Fset_file_times, Finsert_file_contents, Fwrite_region)
5384 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
5385 (Fvisited_file_modtime, Fset_visited_file_modtime):
5386 Support higher-resolution time stamps.
5387
5388 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
5389

5394
5395 * keyboard.c (start_polling, bind_polling_period):
5396 Check for time stamp overflow.
5397 (read_char, kbd_buffer_get_event, timer_start_idle)
5398 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
5399 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
5400 Port to higher-resolution time stamps. Do not assume time_t is signed.
5401 (decode_timer): New function. Timers are now vectors of length 9,
5402 not 8, to accommodate the picosecond component.
5403 (timer_check_2): Use it.
5404
5405 * nsterm.m (select_timeout, timeval_subtract): Remove.
5406 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
5407 as they're a bit more accurate and handle overflow better.
5408 (ns_select): Change prototype to be compatible with pselect.
5409 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
5410 * nsterm.h (ns_select): Adjust prototype.
5411
5412 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
5413 us-resolution time stamps.
5414 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
5415
5416 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
5417
5418 * lisp.h (time_overflow): New decl.
5419 (wait_reading_process_output): First arg is now intmax_t, not int,
5420 to accommodate larger waits.
5421
5422 * process.h (struct Lisp_Process.read_output_delay):
5423 Now counts nanoseconds, not microseconds.
5424 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about

5428 Port to ns-resolution time stamps.
5429 (Faccept_process_output, wait_reading_process_output):
5430 Check for time stamp overflow. Do not assume time_t is signed.
5431 (select_wrapper): Remove; we now use pselect.
5432 (Fprocess_attributes): Now generates ns-resolution time stamps.
5433
5434 * sysdep.c: Include utimens.h. Don't include utime.h
5435 or worry about struct utimbuf; gnulib does that for us now.
5436 (gettimeofday): Remove; gnulib provides a substitute.
5437 (make_timeval): New function.
5438 (set_file_times): Now sets ns-resolution time stamps.
5439 New arg FD; all uses changed.
5440 (time_from_jiffies, ltime_from_jiffies, get_up_time)
5441 (system_process_attributes):
5442 Now returns ns-resolution time stamp. All uses changed.
5443 Check for time stamp overflow.
5444
5445 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
5446 provides a substitute now.
5447
5448 * systime.h: Include timespec.h rather than sys/time.h and time.h,
5449 since it guarantees struct timespec.
5450 (EMACS_TIME): Now struct timespec, so that we can support
5451 ns-resolution time stamps.
5452 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
5453 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
5454 (EMACS_USECS): Remove.
5455 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
5456 so multiply the arg by 1000 before storing it.
5457 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
5458 New macros.
5459 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
5460 Port to ns-resolution time stamps.
5461 (EMACS_TIME_NEG_P): Remove; replaced by....
5462 (EMACS_TIME_SIGN): New macro.

5466 (make_timeval, make_lisp_time, decode_time_components): New decls.
5467 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
5468 that it mishandled time_t overflow. You can't compare by subtracting!
5469 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
5470 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
5471
5472 * term.c: Include <sys/time.h>.
5473 (timeval_to_Time): New function, for proper overflow wraparound.
5474 (term_mouse_position, term_mouse_click): Use it.
5475
5476 * undo.c (record_first_change): Support higher-resolution time stamps
5477 in the undo buffer.
5478 (Fprimitive_undo): Use them when restoring time stamps.
5479
5480 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
5481 (w32_get_internal_run_time):
5482 Port to higher-resolution Emacs time stamps.
5483 (ltime): Now accepts single 64-bit integer, as that's more convenient
5484 for callers.
5485
5486 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
5487
5488 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
5489 for compatibility with pselect. Support ns-resolution time stamps.
5490
5491 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
5492
5493 * xselect.c (wait_for_property_change, x_get_foreign_selection):
5494 Check for time stamp overflow, and support ns-resolution time stamps.
5495
5496 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
5497 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
5498 (timeval_subtract): Remove; no longer needed.
5499 (XTflash, XTring_bell, x_wait_for_event):
5500 Port to ns-resolution time stamps. Don't assume time_t is signed.

5506 2012-06-22 Eli Zaretskii <eliz@gnu.org>
5507
5508 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
5509 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
5510 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
5511 staticidx goes up to 1597 out of 1600 = 0x640.)
5512
5513 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
5514
5515 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

5525 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
5526 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
5527 access to `contents' member of Lisp_Vector objects with AREF and ASET
5528 where appropriate.
5529

5538 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
5539 Callers changed.
5540 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
5541 since tty frames can be explicitly named.
5542 (prepare_menu_bars): Likewise.
5543
5544 * term.c (Ftty_top_frame): New function.
5545
5546 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
5547
5548 Port byte-code-meter to modern targets.
5549 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
5550 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
5551 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
5552 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

5560
5561 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
5562 gets killed during executing of this function (Bug#11665).
5563 Try to always return Qt when the buffer has been actually killed.
5564 (Vkill_buffer_query_functions): In doc-string say that functions
5565 run by this hook should not change the current buffer.
5566
5567 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
5568

5587 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
5588
5589 * lisp.h (eassert): Assume C89 or later.
5590 This removes the need for CHECK.
5591 (CHECK): Remove. Its comments about always evaluating its
5592 argument were confusing, as 'eassert' typically does not evaluate
5593 its argument.
5594
5595 * coding.c (produce_chars): Use ptrdiff_t, not int.
5596
5597 * xterm.c (x_draw_underwave): Check for integer overflow.

5690
5691 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.

5694 row.
5695 (handle_face_prop): Use chunk-relative overlay string index when
5696 indexing into it->string_overlays array. (Bug#11653)

5726 Simplify now that USE_LSB_TAG is always defined.
5727 (TYPEMASK, XINT) [USE_LSB_TAG]: Remove unnecessary cast.
5728 (make_number) [!USE_LSB_TAG]: Use INTMASK; that's simpler.

5740
5741 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
5742 instead of union.
5743 (XLI, XIL): Define.
5744 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):

5755 * w32menu.c (add_menu_item): Likewise.
5756 (w32_menu_display_help): Use XIL instead of checking

5770
5771 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
5772 * alloc.c (make_number) [!defined make_number]:
5773 Remove, as lisp.h always defines this now.
5774 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
5775 (roundup_size): Verify that it is a power of 2.
5776 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
5777 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
5778 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
5779 -DUSE_LSB_TAG=0, to override the automatically-selected default.
5780 USE_LSB_TAG now is always defined to be either 0 or 1.
5781 All uses changed.
5782 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
5783 code works fine either way, and efficiency is not a concern here,
5784 as the union type is for debugging, not for production.
5785 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
5786 Use an inline function on all platforms when using the union type,
5787 since this is simpler and 'static inline' can be used portably
5788 within Emacs now.
5789 (LISP_INITIALLY_ZERO): New macro.
5790 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
5791 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

5871 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
5872
5873 * xdisp.c (vmessage): Treat frame message as multibyte.
5874 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
5875 would generate the diagnostic "Making \302\247 buffer-local while
5876 let-bound!".
5877
5878 2012-06-08 Eli Zaretskii <eliz@gnu.org>
5879
5880 * dispnew.c (showing_window_margins_p): Undo last change, which
5881 was done due to an inadvertent commit.
5882 (adjust_frame_glyphs_for_frame_redisplay): Do call
5883 showing_window_margins_p.

5894 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
5895
5896 2012-06-08 Eli Zaretskii <eliz@gnu.org>
5897
5898 * alloc.c (allocate_vectorlike): Fix last change.

5901
5902 Block-based vector allocation of small vectors.
5903 * lisp.h (struct vectorlike_header): New field `nbytes',
5904 adjust comment accordingly.

5906 to denote vector blocks. Adjust users (live_vector_p,
5907 mark_maybe_pointer, valid_lisp_object_p) accordingly.
5908 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
5909 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
5910 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
5911 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),

5921 or equal to VBLOCK_BYTES_MAX.
5922 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
5923 (init_alloc_once): Add call to init_vectors.
5924
5925 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>

5928
5929 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
5930
5931 * doprnt.c (doprnt): Truncate multibyte char correctly.
5932 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
5933 would mishandle a string argument "Xc" if X was a multibyte
5934 character of length 2: it would truncate after X's first byte
5935 rather than including all of X.
5936
5937 2012-06-06 Chong Yidong <cyd@gnu.org>
5938
5939 * buffer.c (word_wrap): Doc fix.

5964 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
5965 (note_mode_line_or_margin_highlight): If there is no help echo,
5966 use mode-line-default-help-echo. Handle the case where the mouse
5967 position is past the end of the mode line string.
5968
5969 * buffer.c (buffer_local_value_1): New function, split from
5970 Fbuffer_local_value; can return Qunbound.

5985
5986 * minibuf.c (Fassoc_string): Remove duplicate declaration.
5987
5988 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
5989 Convert pctcpu and pctmem to Lisp float properly.
5990 Let the compiler fold better, as 100.0/0x8000 is exact.
5991
5992 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
5993
5994 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

6000
6001 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
6002
6003 For a 'struct window', replace some Lisp_Object fields to
6004 bitfields where appropriate, remove unused fields.
6005 * window.h (struct window): Remove unused 'last_mark_x' and
6006 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
6007 change it's type from Lisp_Object to bitfield.
6008 Change type of 'force_start', 'optional_new_start',
6009 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
6010 fields from Lisp_Object to bitfield. Adjust users accordingly.
6011
6012 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
6013
6014 Pacify gcc -Wdouble-precision when using Xaw.
6015 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
6016 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
6017 Use 'float' consistently, rather than 'float' in most places
6018 and 'double' in a couple of places.
6019
6020 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6021
6022 * xdisp.c (handle_stop): Detect whether we have overlay strings
6023 loaded by testing it->current.overlay_string_index to be
6024 non-negative, instead of checking whether n_overlay_strings is
6025 positive. (Bug#11587)
6026
6027 2012-05-31 Chong Yidong <cyd@gnu.org>
6028
6029 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

6032
6033 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6034
6035 * search.c (search_buffer): Remove calls to
6036 r_alloc_inhibit_buffer_relocation, as it is now called by
6037 maybe_unify_char, which was the cause of relocation of buffer text
6038 in bug#11519.
6039
6040 2012-05-31 Eli Zaretskii <eliz@gnu.org>
6041
6042 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
6043 for the duration of call to load_charset, to avoid problems with
6044 callers of maybe_unify_char that access buffer text through C
6045 pointers.
6046
6047 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
6048 decrement the inhibition flag, instead of just setting or
6049 resetting it.

6052
6053 Remove obsolete '#define static' cruft.
6054 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
6055 This #undef was "temporary" in 2000; it is no longer needed

6058 (gray_bitmap_bits): Remove; no longer needed.
6059 All uses replaced with definiens.

6064 Clean up __executable_start, monstartup when --enable-profiling.
6065 The following changes affect the code only when profiling.
6066 * dispnew.c (__executable_start): Rename from safe_bcopy.
6067 Define only on platforms that need it.
6068 * emacs.c: Include <sys/gmon.h> when profiling.
6069 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
6070 (__executable_start): Remove decl, since lisp.h does it now.
6071 (safe_bcopy): Remove decl; no longer has that name.
6072 (main): Coalesce #if into single bit of code, for simplicity.
6073 Cast pointers to uintptr_t, since standard libraries want integers
6074 and not pointers.
6075 * lisp.h (__executable_start): New decl.
6076
6077 2012-05-31 Glenn Morris <rgm@gnu.org>

6102 Do not create empty overlays with the evaporate property (Bug#9642).
6103 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
6104 Bug#9642, but explicitly check that the buffer the overlay would
6105 be moved to is live and rearrange lines to make sure that errors
6106 will not put the overlay in an inconsistent state.
6107 (Fdelete_overlay): Cosmetics.
6108
6109 2012-05-28 Eli Zaretskii <eliz@gnu.org>
6110
6111 * w32term.c (my_bring_window_to_top): New function.
6112 (x_raise_frame): Use handle returned by DeferWindowPos, which
6113 could be different from the original one.
6114 Call my_bring_window_to_top instead of my_set_foreground_window.
6115 (Bug#11513)
6116
6117 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
6118 by calling BringWindowToTop.

6124
6125 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
6126 This avoids undefined behavior that might cause the eassert
6127 to not catch an out-of-range value.
6128
6129 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
6130

6144
6145 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
6146 Only r_alloc_inhibit_buffer_relocation needed to be added;
6147 the others were already declared.
6148
6149 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
6150 before checking whether it's out of range. Put the check inside
6151 eassert. See
6152 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
6153

6163
6164 * buffer.c [REL_ALLOC]: Remove prototypes of

6166 they are now on lisp.h.
6167
6168 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
6169
6170 * search.c (search_buffer): Use it to inhibit relocation of buffer
6171 text while re_search_2 is doing its job, because re_search_2 is
6172 passed C pointers to buffer text. (Bug#11519)
6173
6174 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
6175 Update value to 24.
6176
6177 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
6178 state after an additional call to move_it_in_display_line_to, keep
6179 the values of it->max_ascent and it->max_descent found for the
6180 entire line.
6181 (pos_visible_p): Revert the comparison against bottom_y to what it
6182 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.

6186
6187 Fix coding-related core dumps with gcc -ftrapv.
6188 The code was computing A - B, where A and B are pointers, and B is
6189 random garbage. This can lead to core dumps on platforms that
6190 have special pointer registers, and it also leads to core dumps on
6191 x86-64 when compiled with gcc -ftrapv. The fix is to compute
6192 A - B only when B is initialized properly.
6193 * coding.c (coding_set_source, coding_set_destination): Return void.
6194 (coding_change_source, coding_change_destinations): New functions,
6195 with the old behaviors of coding_set_source and coding_set_destination.
6196 All callers that need an offset changed to use these new functions.
6197

6206 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
6207
6208 * w32console.c: Include window.h.
6209 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
6210 New functions.
6211 (initialize_w32_display): Initialize mouse-highlight data.
6212
6213 * w32inevt.c: Include termchar.h and window.h.
6214 (do_mouse_event): Support mouse-autoselect-window. When the mouse
6215 moves, call note_mouse_highlight. If help_echo changed, call
6216 gen_help_event to produce help-echo message in the echo area.
6217 Call clear_mouse_face if mouse_face_hidden is set in the mouse
6218 highlight info.
6219
6220 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
6221
6222 * lread.c (read1): Simplify slightly to avoid an overflow warning
6223 with GCC 4.7.0 on x86-64.
6224
6225 2012-05-26 Eli Zaretskii <eliz@gnu.org>
6226
6227 * bidi.c (bidi_mirror_char): Revert last change: an int is
6228 definitely wide enough here.
6229
6230 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
6231
6232 Fix integer width and related bugs (Bug#9874).

6240 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
6241 (mark_vectorlike):
6242 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6243 (allocate_pseudovector):
6244 Use int, not EMACS_INT, where int is wide enough.
6245 (inhibit_garbage_collection, Fgarbage_collect):
6246 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6247 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
6248 int might not be wide enough.

6264 (Foverlay_recenter, last_overlay_modification_hooks_used)
6265 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
6266 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6267 (validate_region): Omit unnecessary test for b <= e,
6268 since that's guaranteed by the previous test.
6269 (adjust_overlays_for_delete): Avoid pos + length overflow.
6270 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
6271 (report_overlay_modification):
6272 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6273 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
6274 Omit pointer cast, which isn't needed anyway, and doesn't work
6275 after the EMACS_INT -> ptrdiff_t change.
6276 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
6277 * buffer.h: Adjust decls to match defn changes elsewhere.

6282 not int, to avoid needless 32-bit limit on 64-bit hosts.
6283 (exec_byte_code): Use tighter memory-full test, one that checks
6284 for alloca overflow. Don't compute the address of the object just
6285 before an array, as that's not portable. Use EMACS_INT, not
6286 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
6287 * callint.c (Fcall_interactively):
6288 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6289 * callproc.c (call_process_kill, Fcall_process):
6290 Don't assume pid_t fits into an Emacs fixnum.

6299 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
6300 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6301 (casify_object): Avoid integer overflow when overallocating buffer.
6302 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
6303 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
6304 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
6305 * category.h (CATEGORYP): Don't assume arg is nonnegative.
6306 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
6307 integers are now checked earlier. All uses replaced with XINT.
6308 (ccl_driver):
6309 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6310 For CCL_MapSingle, check that content and value are in int range.
6311 (ccl_driver, Fregister_code_conversion_map):
6312 Check that Vcode_version_map_vector is a vector.
6313 (resolve_symbol_ccl_program): Check that vector header is in range.
6314 Always copy the vector, so that we can check its contents reliably
6315 now rather than having to recheck each instruction as it's being
6316 executed. Check that vector words fit in 'int'.
6317 (ccl_get_compiled_code, Fregister_ccl_program)
6318 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
6319 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
6320 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
6321 contents are in range.
6322 (Fccl_execute_on_string): Check that status is in range.
6323 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
6324 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
6325 Accept and return EMACS_INT, not int, because callers can pass values
6326 out of 'int' range.

6332 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6333 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
6334 avoid mishandling large integers.
6335 * character.h: Adjust decls to match defn changes elsewhere.
6336 * charset.c (load_charset_map_from_file, find_charsets_in_text)

6339 (load_charset_map_from_file): Redo idx calculation to avoid overflow.

6341 Don't assume fixnum fits in int.
6342 (load_charset_map_from_vector, Fmap_charset_chars):

6344 (Fdefine_charset_internal): Check ranges here, more carefully.
6345 Don't rely on undefined behavior with signed left shift overflow.
6346 Don't assume unsigned int fits into fixnum, or that fixnum fits
6347 into unsigned int. Don't require max_code to be a valid fixnum;
6348 that's not true for gb10830 4-byte on a 32-bit host. Allow
6349 invalid_code to be a cons, for the same reason. Require code_offset
6350 to be a character. Avoid int overflow if max_char is close
6351 to INT_MAX.
6352 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
6353 this is intended anyway and avoids some undefined behavior.
6354 (load_charset_map): Pass unsigned, not int, as 2nd arg of
6355 INDEX_TO_CODE_POINT, as that's what it expects.
6356 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
6357 * charset.h (DECODE_CHAR): Return int, not unsigned;
6358 this is what was intended anyway, and it avoids undefined behavior.
6359 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
6360 integer-overflow issues.
6361 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
6362 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
6363 where the argument is EMACS_INT, and this behavior is not intended.
6364 * chartab.c (Fmake_char_table, Fset_char_table_range)
6365 (uniprop_get_decoder, uniprop_get_encoder):
6366 Don't assume fixnum fits in int.
6367 * cmds.c (move_point): New function, that does the gist of
6368 Fforward_char and Fbackward_char, but does so while checking
6369 for integer overflow more accurately.
6370 (Fforward_char, Fbackward_char): Use it.
6371 (Fforward_line, Fend_of_line, internal_self_insert)
6372 (internal_self_insert):
6373 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
6374 Fix a FIXME, by checking for integer overflow when calculating
6375 target_clm and actual_clm.

6406 (get_translation, handle_composition_annotation, consume_chars):
6407 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
6408 (consume_chars): Rewrite to not calculate an address outside buffer.
6409 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
6410 Don't access memory outside of the args array.
6411 (Fdefine_coding_system_internal): Check for charset-id overflow.
6412 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
6413 result of ENCODE_CHAR.

6432 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
6433 Do not attempt to compute the address of the object just before a

7051 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
7052
7053 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.

7055
7056 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
7057
7058 Remove src/m/*.
7059 This directory predates autoconf and is no longer needed nowadays.
7060 Move its few remaining bits of functionality to where they're needed.
7061 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
7062 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:

7070 (EMACS_UINT): Define unconditionally now.
7071 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
7072 (BITS_PER_EMACS_INT): New constants, replacing
7073 what used to be in config.h, but not useful in #if.
7074 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
7075 define them any more.
7076 (VAL_MAX): New macro.

7084 Move here from removed file m/intel386.h.
7085 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
7086 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
7087
7088 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
7089
7090 Assume C89 or later.

7143 (Fword_search_forward_lax): Move functions to isearch.el
7144 (bug#10145, bug#11381).
7145
7146 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
7147
7148 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
7149
7150 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
7151
7152 * lread.c (init_obarray): Declare Qt and Qnil as special.
7153
7154 2012-05-14 Glenn Morris <rgm@gnu.org>
7155
7156 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
7157 Put "libexec" before "bin", for the sake of init_callproc_1.
7158
7159 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7160
7161 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
7162
7163 * unexaix.c: Port to more-recent AIX compilers.
7164 (report_error, report_error_1, make_hdr, copy_sym)
7165 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
7166 Make arguments const char *, not char *, to avoid violations of C
7167 standard and to fix some AIX warnings reported by Gilles Pion.
7168
7169 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7170
7171 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
7172 already have overlays loaded.
7173 (handle_single_display_spec): Before returning without displaying
7174 fringe bitmap, synchronize the bidi iterator with the main display
7175 iterator, by calling iterate_out_of_display_property.
7176 (iterate_out_of_display_property): Detect buffer iteration by
7177 testing that it->string is a Lisp string.
7178 (get_next_display_element): When the current object is exhausted,
7179 and there's something on it->stack, call set_iterator_to_next to
7180 proceed with what's on the stack, instead of returning zero.
7181 (set_iterator_to_next): If called at the end of a Lisp string,
7182 proceed to consider_string_end without incrementing string
7183 position. Don't increment display vector index past the end of
7184 the display vector. (Bug#11417)
7185 (pos_visible_p): Don't report a position visible when move_it_to
7186 stopped at the last line of window, which happens to be scanned
7187 backwards by the bidi iteration. (Bug#11464)
7188
7189 2012-05-14 Eli Zaretskii <eliz@gnu.org>
7190
7191 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
7192 and right-margin display specs even if the spec is invalid or we
7193 are on a TTY, and thus unable to display on the fringes.
7194 That's because the text with the property will not be displayed anyway,
7195 so we need to signal to the caller that this is a "replacing"
7196 display spec. This fixes display when the spec is invalid or we
7197 are on a TTY.
7198
7199 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
7200
7201 * unexaix.c (make_hdr): Fix typo in prototype.
7202 This bug broke the build on AIX. Problem reported by Gilles Pion.
7203

7205
7206 * keyboard.c (kbd_buffer_get_event): Read special events also in

7227 * xdisp.c (hourglass_started): Remove.
7228
7229 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
7230
7231 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
7232 Update dependencies.
7233
7234 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
7235
7236 * xgselect.c (xg_select): Put maxfds+1 into a var.

7238
7239 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
7240
7241 2012-05-10 Dave Abrahams <dave@boostpro.com>
7242
7243 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
7244 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
7245
7246 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
7247

7249 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
7250 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
7251 Initialize xd_registered_buses.
7252
7253 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
7254
7255 Untag more efficiently if USE_LSB_TAG.
7256 This is based on a proposal by YAMAMOTO Mitsuharu in
7257 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
7258 For an admittedly artificial (nth 8000 longlist) benchmark on
7259 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
7260 Emacs's overall text size by 1%.
7261 * lisp.h (XUNTAG): New macro.
7262 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
7263 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
7264 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
7265 * eval.c (Fautoload):
7266 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
7267 * frame.h (XFRAME): Use XUNTAG.
7268
7269 Port recent dbusbind.c changes to 32-bit --with-wide-int.
7270 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
7271 Remove unportable assumptions about print widths of types like
7272 dbus_uint32_t.
7273 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
7274 intptr_t when converting between pointer and integer, to avoid GCC
7275 warnings about wrong width.
7276
7277 2012-05-09 Eli Zaretskii <eliz@gnu.org>
7278
7279 * w32proc.c (new_child): Force Windows to reserve only 64KB of
7280 stack for each reader_thread, instead of defaulting to 8MB
7281 determined by the linker. This avoids failures in creating
7282 subprocesses on Windows 7, see the discussion in this thread:
7283 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
7284
7285 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
7286
7287 Fix up display of the *Minibuf-0* buffer in the mini window.
7288 * keyboard.c (read_char): Don't clear the echo area if there's no
7289 message to clear.
7290 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
7291 contents of *Minibuf-0*) if there's no message displayed in its stead.
7292
7293 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
7294
7295 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
7296 batch mode.
7297
7298 2012-05-06 Chong Yidong <cyd@gnu.org>
7299
7300 * lisp.mk (lisp): Update.
7301
7302 2012-05-05 Jim Meyering <meyering@redhat.com>
7303
7304 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
7305
7306 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
7307
7308 * data.c (PUT_ERROR): New macro.
7309 (syms_of_data): Use it. Add new error type `user-error'.
7310 * undo.c (user_error): New function.
7311 (Fprimitive_undo): Use it.
7312 * print.c (print_error_message): Adjust print style for `user-error'.
7313 * keyboard.c (user_error): New function.
7314 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
7315
7316 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
7317
7318 Do not limit current-time-string to years 1000..9999.
7319 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
7320 (Fcurrent_time_string): Support any year that is supported by the
7321 underlying localtime representation. Don't use asctime, as it
7322 has undefined behavior for years outside the range -999..9999.
7323
7324 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
7325
7326 Fix race conditions involving setenv, gmtime, localtime, asctime.
7327 Without this fix, interrupts could mess up code that uses these
7328 nonreentrant functions, since setting TZ invalidates existing
7329 tm_zone or tzname values, and since most of these functions return
7330 pointers to static storage.
7331 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
7332 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
7333 Grow the critical sections to include not just invoking
7334 localtime/gmtime, but also accessing these functions' results
7335 including their tm_zone values if any, and any related TZ setting.
7336 (format_time_string): Last arg is now struct tm *, not struct tm **,
7337 so that the struct tm is saved in the critical section.
7338 All callers changed. Simplify allocation of initial buffer, partly
7339 motivated by the fact that memory allocation needs to be outside
7340 the critical section.
7341
7342 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
7343
7344 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
7345 with RESET_INTERVAL.
7346
7347 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7348 Remove duplicated buffer name initialization.
7349
7350 2012-05-02 Jim Meyering <jim@meyering.net>
7351
7352 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
7353
7354 * xfns.c (x_window): Use xstrdup (Bug#11375).
7355
7356 2012-05-02 Eli Zaretskii <eliz@gnu.org>
7357
7358 * xdisp.c (pos_visible_p): If already at a newline from the
7359 display string before the 'while' loop, don't walk back the glyphs
7360 from it3.glyph_row. Solves assertion violation when the display
7361 string begins with a newline (egg.el). (Bug#11367)
7362
7363 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
7364
7365 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
7366 Move to simple.el.
7367
7368 2012-05-01 Glenn Morris <rgm@gnu.org>
7369
7370 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
7371 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
7372 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
7373 All were removed before 23.1.
7374
7375 * dispnew.c: Remove HAVE_LIBNCURSES test;
7376 it is always true on relevant platforms.
7377
7378 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
7379 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
7380
7381 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
7382
7383 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
7384
7385 * .gdbinit (xpr): Remove checks for no longer existing misc types.
7386 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
7387 Remove.
7388
7389 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
7390
7391 Do not avoid creating empty evaporating overlays (Bug#9642).
7392 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
7393 That is, do not delete an evaporating overlay if it becomes
7394 empty after its bounds are adjusted to fit within its buffer.
7395 This fix caused other problems, and I'm reverting it until we get
7396 to the bottom of them.
7397
7398 2012-04-27 Chong Yidong <cyd@gnu.org>
7399
7400 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
7401
7402 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7403
7404 * xdisp.c (pos_visible_p): If the window start position is beyond
7405 ZV, start the display from buffer beginning. Prevents assertion
7406 violation in init_iterator when the minibuffer window is scrolled
7407 via the scroll bar.
7408
7409 * window.c (window_scroll_pixel_based): Likewise.
7410
7411 2012-04-27 Chong Yidong <cyd@gnu.org>
7412
7413 * keymap.c (where_is_internal): Doc fix (Bug#10872).
7414
7415 2012-04-27 Glenn Morris <rgm@gnu.org>
7416
7417 * fileio.c (Fcopy_file, Fset_file_selinux_context):

7419
7420 2012-04-27 Eli Zaretskii <eliz@gnu.org>
7421
7422 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
7423 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
7424
7425 2012-04-26 Eli Zaretskii <eliz@gnu.org>
7426
7427 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
7428 display element, check also the underlying string or buffer
7429 character. (Bug#11341)
7430
7431 * w32menu.c: Include w32heap.h.
7432 (add_menu_item): If the call to AppendMenuW (via
7433 unicode_append_menu) fails, disable Unicode menus only if we are
7434 running on Windows 9X/Me.
7435
7436 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
7437
7438 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
7439 (xgetint): Add missing shift for LSB tags.
7440
7441 2012-04-24 Martin Rudalics <rudalics@gmx.at>
7442
7443 * keyboard.c (read_char): Don't wipe echo area for select window
7444 events: These might get delayed via `mouse-autoselect-window'
7445 (Bug#11304).
7446
7447 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
7448
7449 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
7450 manipulation of :loaded-from data.
7451
7452 2012-04-23 Juanma Barranquero <lekktu@gmail.com>

7454 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
7455 now a cons (bug#11311).
7456
7457 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
7458
7459 Do not create empty overlays with the evaporate property (Bug#9642).
7460 * buffer.c (Fmove_overlay): Delete an evaporating overlay
7461 if it becomes empty after its bounds are adjusted to fit within
7462 its buffer. Without this fix, in a nonempty buffer (let ((o
7463 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
7464 yields an empty overlay that has the evaporate property, which is
7465 not supposed to happen.
7466
7467 Fix minor GTK3 problems found by static checking.
7468 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
7469 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
7470 (struct _EmacsFixedClass, emacs_fixed_get_type):

7473 (emacs_fixed_class_init): Omit unused local.
7474 (emacs_fixed_child_type): Remove; unused.

7477 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
7478 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
7479 (EMACS_FIXED_GET_CLASS): Remove; unused.

7483 Problem reported by Juanma Barranquero for Windows -Wunused-function.
7484
7485 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7486
7487 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
7488 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
7489 (__malloc_size_t, __malloc_ptrdiff_t):
7490 Remove. All uses removed, replaced by the definiens if needed,
7491 since we can assume C89 or better now.
7492 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
7493 (protect_malloc_state, align, get_contiguous_space)
7494 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

7500 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
7501 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
7502 Define using prototypes, not old style.
7503 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
7504 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.

7566
7567 * alloc.c: Handle unusual debugging option combinations.
7568 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
7569 since the two debugging options are incompatible.
7570 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
7571 is defined.
7572 (mem_init, mem_insert, mem_insert_fixup):
7573 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

7580 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
7581
7582 * sysdep.c [__FreeBSD__]: Minor cleanups.
7583 (list_system_processes, system_process_attributes) [__FreeBSD__]:
7584 Use Emacs indenting style more consistently. Avoid some casts.

7596 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
7597
7598 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
7599 It is never used otherwise.
7600

7603 * print.c (print_preprocess): Only check print_depth if print-circle
7604 is nil.

7626 farther than the first row after the header line, if any.
7627 Don't consider the header-line row as "partially visible", even if
7628 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
7629
7630 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

7644 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
7645 -Wunused-result, -Wunused-variable. This should go away once
7646 the Emacs and Gnulib regex code is merged.

7665 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
7666 New extern decls, to avoid calling undeclared functions.
7667 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
7668 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
7669 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
7670 (NEED_MEM_INSERT): New macro.
7671 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
7672 Remove one incorrect comment and fix another.
7673

7675 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
7676 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
7677 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.

7682 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
7683 (r_alloc_free) [REL_ALLOC]: Move decls from here ...
7684 * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
7685 [REL_ALLOC]: ... to here, to check interface.
7686 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
7687 Remove decls. This fixes an "It stinks!".

7700 (MARKER_BLOCK_SIZE, struct marker_block): Use union
7701 aligned_Lisp_Misc instead of union Lisp_Misc.
7702 (Fmake_symbol, allocate_misc, gc_sweep): Adjust.
7703
7704 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
7705
7706 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
7707 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
7708 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
7709 * s/netbsd.h, s/sol2-6.h:
7710 Remove definition of GC_MARK_STACK, since the default now works.
7711 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
7712 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's

7714 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
7715
7716 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
7717
7718 * lread.c (lisp_file_lexically_bound_p):

7722
7723 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

7738
7739 2012-04-11 Daniel Colascione <dancol@dancol.org>
7740
7741 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
7742 against is gone. It's better to use vfork now so that when Cygwin
7743 gains a new, working vfork, we use it automatically (bug#10398).
7744
7745 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
7746

7765 * w32.c (w32_delayed_load): Record the full path of the library
7766 being loaded (bug#10424).
7767
7768 2012-04-09 Glenn Morris <rgm@gnu.org>
7769
7770 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
7771 not just in the obarray, before snarfing them. (Bug#11036)
7772
7773 * Makefile.in ($(leimdir)/leim-list.el):
7774 Pass EMACS rather than BUILT_EMACS.
7775
7776 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
7777
7778 * process.c (make_process):
7779 * process.h: Add integer `gnutls_handshakes_tried' member to
7780 process struct.
7781
7782 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
7783 Add convenience `GNUTLS_LOG2i' macro.
7784
7785 * gnutls.c (gnutls_log_function2i): Convenience log function.
7786 (emacs_gnutls_read): Use new log functions,
7787 `gnutls_handshakes_tried' process member, and
7788 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
7789 attempts per process (connection).
7790
7791 2012-04-09 Chong Yidong <cyd@gnu.org>
7792
7793 * eval.c (Fuser_variable_p, user_variable_p_eh)
7794 (lisp_indirect_variable): Functions deleted.
7795 (Fdefvar): Caller changed.
7796

7798 * minibuf.c (Fread_variable): Callers changed.
7799
7800 2012-04-09 Eli Zaretskii <eliz@gnu.org>
7801
7802 * xdisp.c (set_cursor_from_row): If the display string appears in
7803 the buffer at position that is closer to point than the position
7804 after the display string, display the cursor on the first glyph of
7805 the display string. Fixes cursor display when a 'display' text
7806 property immediately follows invisible text. (Bug#11094)
7807
7808 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
7809
7810 composite.c: use 'double' consistently
7811 * composite.c (get_composition_id): Use 'double' consistently
7812 instead of converting 'float' to 'double' and vice versa; this is
7813 easier to understand and avoids a GCC warning.
7814
7815 2012-04-09 Glenn Morris <rgm@gnu.org>
7816
7817 * Makefile.in: Generate leim-list with bootstrap-emacs, in

7837 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
7838
7839 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
7840 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
7841 (mark_memory): Mark Lisp_Objects only if pointers might hide in
7842 objects, as mark_maybe_pointer will catch them otherwise.
7843 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
7844 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
7845
7846 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
7847
7848 Fix typo that broke non-Windows builds.
7849 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
7850
7851 2012-04-07 Eli Zaretskii <eliz@gnu.org>
7852
7853 Support building on MS-Windows with libxml2.
7854
7855 * makefile.w32-in (OBJ2): Add xml.$(O).
7856 (GLOBAL_SOURCES): Add xml.c.

7861 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
7862 [!WINDOWSNT]: New macros.
7863 (init_libxml2_functions, libxml2_loaded_p): New functions.
7864 (parse_region): Call fn_xmlCheckVersion instead of using the macro
7865 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
7866 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
7867 Calls xmlCleanupParser only if libxml2 was loaded (or statically
7868 linked in).
7869 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
7870 Call init_libxml2_functions before calling libxml2 functions.
7871 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
7872
7873 * emacs.c: Don't include libxml/parser.h.
7874 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
7875 xmlCleanupParser directly.
7876
7877 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
7878
7879 2012-04-07 Eli Zaretskii <eliz@gnu.org>
7880
7881 * indent.c (Fvertical_motion): If there is a display string at
7882 point, use it.vpos to compute how many lines to backtrack after
7883 move_it_to point. (Bug#11133)
7884
7885 2012-04-06 Eli Zaretskii <eliz@gnu.org>
7886
7887 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
7888 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
7889 about subtle differences between FETCH_CHAR* and STRING_CHAR*
7890 macros related to unification of CJK characters. For the details,
7891 see the discussion following the message here:
7892 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
7893
7894 2012-04-04 Chong Yidong <cyd@gnu.org>
7895
7896 * keyboard.c (Vdelayed_warnings_list): Doc fix.
7897
7898 2012-04-01 Eli Zaretskii <eliz@gnu.org>
7899
7900 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

7904
7905 * w32menu.c (is_simple_dialog): Properly check lisp types.
7906 (Bug#11141)
7907
7908 2012-03-31 Eli Zaretskii <eliz@gnu.org>
7909
7910 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
7911 position we get to after a call to move_it_to fails the
7912 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
7913 only if we wind up in a string from display property. (Bug#11063)
7914
7915 * window.c (Fdelete_other_windows_internal): Invalidate the row
7916 and column information about mouse highlight, so that redisplay
7917 restores it after reallocating the glyph matrices. (Bug#7464)
7918
7919 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
7920 string comes from a `display' text property, use the buffer
7921 position of that property as if we actually saw that position in
7922 the row's glyphs.
7923 (move_it_by_lines): Remove the assertion that
7924 "it->current_x == 0 && it->hpos == 0" which can be legitimately
7925 violated when there's a before-string at the beginning of a line.
7926 (Bug#11063)
7927
7928 2012-03-30 Eli Zaretskii <eliz@gnu.org>
7929
7930 * xdisp.c (append_space_for_newline): If the default face was
7931 remapped, use the remapped face for the appended newline.
7932 (extend_face_to_end_of_line): Use the remapped default face for
7933 extending the face to the end of the line.
7934 (display_line): Call extend_face_to_end_of_line when the default
7935 face was remapped. (Bug#11068)
7936
7937 2012-03-29 Eli Zaretskii <eliz@gnu.org>
7938
7939 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

7950 2012-03-26 Kenichi Handa <handa@m17n.org>
7951
7952 * dispextern.h (struct glyph): Fix previous change. Change the
7953 bit length of glyphless.ch to 25 (Bug#11082).
7954
7955 2012-03-26 Chong Yidong <cyd@gnu.org>
7956
7957 * keyboard.c (Vselection_inhibit_update_commands): New variable.
7958 (command_loop_1): Use it; inhibit selection update for
7959 handle-select-window too (Bug#8996).
7960
7961 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
7962
7963 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
7964
7965 2012-03-25 Kenichi Handa <handa@m17n.org>
7966
7967 * dispextern.h (struct glyph): Change the bit length of
7968 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
7969
7970 2012-03-24 Eli Zaretskii <eliz@gnu.org>
7971
7972 * s/ms-w32.h (tzname): Include time.h before redirecting to
7973 _tzname. Fixes the MSVC build. (Bug#9960)
7974
7975 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
7976
7977 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
7978 characters.

7982
7983 2012-03-23 Eli Zaretskii <eliz@gnu.org>
7984
7985 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
7986 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
7987 when fetching a multibyte character consumes more bytes than
7988 CHAR_BYTES returns, due to unification of CJK characters in
7989 string_char. (Bug#11073)
7990
7991 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
7992
7993 * process.c (wait_reading_process_output): Handle pty disconnect

8004
8005 2012-03-21 Chong Yidong <cyd@gnu.org>
8006

8018 to reflect default non-nil value of redisplay-dont-pause.
8019
8020 2012-03-19 Kenichi Handa <handa@m17n.org>
8021
8022 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
8023 it fit in a valid range (Bug#11003).
8024
8025 2012-03-18 Eli Zaretskii <eliz@gnu.org>
8026
8027 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
8028 that is not from display property, accept the row as a "cursor
8029 row" if one of the string's character has a non-nil `cursor'
8030 property. Fixes cursor positioning when there are newlines in
8031 overlay strings, e.g. in icomplete.el. (Bug#11035)
8032
8033 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
8034
8035 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
8036
8037 2012-03-12 Chong Yidong <cyd@gnu.org>
8038
8039 * eval.c (inhibit_lisp_code): Rename from
8040 inhibit_window_configuration_change_hook; move from window.c.
8041
8042 * xfns.c (unwind_create_frame_1, Fx_create_frame):
8043 * window.c (run_window_configuration_change_hook)
8044 (syms_of_window): Callers changed.
8045
8046 2012-03-11 Chong Yidong <cyd@gnu.org>
8047
8048 * keymap.c (Fkey_description): Doc fix (Bug#9700).
8049
8050 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
8051
8052 2012-03-10 Chong Yidong <cyd@gnu.org>
8053
8054 * frame.c (other_visible_frames): Don't assume the selected frame
8055 is visible (Bug#10955).

8058
8059 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
8060
8061 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
8062
8063 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
8064 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than

8076 comments.
8077 (redisplay_window): Pass to move_it_vertically the margin in
8078 pixels, not in screen lines.
8079
8080 2012-03-02 Glenn Morris <rgm@gnu.org>
8081

8093
8094 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
8095 Suggested by Stefan Monnier in
8096 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
8097 * alloc.c (widen_to_Lisp_Object): New static function.
8098 (mark_memory): Also mark Lisp_Objects by fetching pointer words
8099 and widening them to Lisp_Objects. This would work even if
8100 USE_LSB_TAG is defined and wide integers are used, which might
8101 happen in a future version of Emacs.
8102
8103 2012-02-25 Chong Yidong <cyd@gnu.org>
8104
8105 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
8106 Doc fix.
8107
8108 * xselect.c (Fx_selection_exists_p): Doc fix.
8109 (x_clipboard_manager_save_all): Print an informative message
8110 before saving to clipboard manager.
8111
8112 2012-02-24 Chong Yidong <cyd@gnu.org>
8113
8114 * keyboard.c (process_special_events): Handle all X selection
8115 requests in kbd_buffer, not just the next one (Bug#8869).
8116
8117 2012-02-23 Chong Yidong <cyd@gnu.org>
8118
8119 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
8120 call when setting menu-bar-lines and tool-bar-lines parameters.
8121 (unwind_create_frame_1): New helper function.
8122
8123 * window.c (inhibit_window_configuration_change_hook): New var.

8126

8142 when computing $valmask.
8143
8144 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
8145 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
8146 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
8147 It's useless in that case, and it can cause problems on hosts
8148 that allocate halves of EMACS_INT values separately.
8149 Reported by Dan Horák. Diagnosed by Andreas Schwab in
8150 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
8151 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
8152 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
8153 it avoids undefined behavior on hosts where shifting right by more
8154 than the word width has undefined behavior.
8155

8178 2012-02-15 Chong Yidong <cyd@gnu.org>
8179

8202 highlight (Bug#9904).
8203
8204 2012-02-12 Glenn Morris <rgm@gnu.org>

8278
8279 Handle overflow when computing char display width (Bug#9496).
8280 * character.c (char_width): Return EMACS_INT, not int.
8281 (char_width, c_string_width): Check for overflow when
8282 computing the width; this is possible now that individual
8283 characters can have unbounded width. Problem introduced
8284 by merge from Emacs 23 on 2012-01-19.
8285
8286 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

8426 (Fmake_directory_internal): Use it.

8933 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
8934 Otherwise, valgrind does not work on some platforms.
8935 Problem reported by Andreas Schwab in
8936 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
8937 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
8938 is set, removing the need for VIRT_ADDRESS_VARIES.
8939 (PURE_P): Use a more-efficient implementation that needs just one
8940 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
8941 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
8942 to 4 (xorl, subq, cmpq, setbe).
8943 * alloc.c (pure): Always extern now, since that's the
8944 VIRT_ADDR_VARIES behavior.
8945 (PURE_POINTER_P): Use a single comparison, not two, for
8946 consistency with the new puresize.h.
8947 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
8948 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
8949 Remove VIRT_ADDR_VARIES no longer needed.

8954 (erase_phys_cursor, update_window_cursor, show_mouse_face)
8955 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
8956 behave as if the cursor position were at the window margin.
8957
8958 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
8959 and the cursor position is out of bounds, behave as if the cursor
8960 position were at the window margin. (Bug#10075)
8961
8962 2011-11-18 Chong Yidong <cyd@gnu.org>
8963

8983 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
8984
8985 * xdisp.c (row_hash): New function, body extracted from

8988 hash code inline.
8989
8990 * dispnew.c (verify_row_hash): Call row_hash for computing the

9030
9031 2011-11-14 Eli Zaretskii <eliz@gnu.org>
9032
9033 * xdisp.c (display_line): Move the call to
9034 highlight_trailing_whitespace before the call to
9035 compute_line_metrics, since the latter needs to see the final
9036 faces of all the glyphs to compute ROW's hash value.
9037 Fixes assertion violations in row_equal_p. (Bug#10035)
9038
9039 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
9040
9041 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
9042 just return (bug#10044).
9043
9044 2011-11-12 Eli Zaretskii <eliz@gnu.org>
9045
9046 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
9047 with user-defined heap size. Bump the default size of the temacs
9048 heap to 27MB, to avoid memory warning when running temacs.
9049 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
9050
9051 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
9052 current_matrix and desired_matrix. (Bug#9990)

9136
9137 2011-11-07 Martin Rudalics <rudalics@gmx.at>
9138

9155 (which_symbols): Use it.
9156
9157 2011-11-07 Kenichi Handa <handa@m17n.org>

9178 (window_box_width, window_box_left, window_box_left_offset)
9179 (window_box_right, window_box_right_offset): Declare extern.
9180 Otherwise, these inline functions do not conform to C99 and
9181 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
9182 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
9183 * intervals.c (adjust_intervals_for_insertion)

9186 (static_offset_intervals): Remove.
9187 (offset_intervals): Rewrite using the old contents of
9188 static_offset_intervals. The old version didn't conform to C99
9189 because an extern inline function contained a reference to an

9212 (Fwindow_vscroll): Doc fix.
9213 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
9214 argument, since it makes no sense to pass a live window and for
9215 consistency with window-child.

9336 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
9337 past the beginning of the current glyph matrix.
9338
9339 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
9340
9341 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
9342 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
9343 HAVE_GTK3 (Bug#9869).
9344
9345 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
9346 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
9347
9348 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
9349
9350 * xterm.c: Declare x_handle_net_wm_state to return int.
9351 (handle_one_xevent): Check if we are iconified but don't have
9352 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
9353 (get_current_wm_state): Return non-zero if not hidden,
9354 check for _NET_WM_STATE_HIDDEN (Bug#9893).
9355 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
9356 (x_handle_net_wm_state): Return what get_current_wm_state returns.
9357 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
9358
9359 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
9360
9361 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
9362 so that this new function doesn't get optimized away by a
9363 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
9364
9365 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
9366
9367 * frame.h (MOUSE_HL_INFO): Remove excess parens.

9372 * .gdbinit (xprintbytestr): New command.
9373 (xwhichsymbols): Rename from `which'; all callers changed.
9374 (xbytecode): Print the byte-code string as well.
9375
9376 2011-10-29 Kim Storm <storm@cua.dk>
9377
9378 * alloc.c (which_symbols): New function.
9379
9380 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
9381
9382 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
9383 line. (Bug#9903)
9384
9385 2011-10-29 Glenn Morris <rgm@gnu.org>
9386
9387 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
9388 Not clear what it was for, and it causes various bugs. (Bug#9839)
9389
9390 2011-10-28 Eli Zaretskii <eliz@gnu.org>
9391
9392 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
9393 possible random value that matches one of those tested as
9394 condition to clear the mouse face.
9395
9396 2011-10-28 Chong Yidong <cyd@gnu.org>
9397
9398 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
9399
9400 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
9401
9402 * window.c (make_window): Initialize phys_cursor_on_p.
9403
9404 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
9405
9406 * lisp.h (struct Lisp_Symbol): Update comments.
9407
9408 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
9409
9410 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
9411
9412 2011-10-28 Eli Zaretskii <eliz@gnu.org>
9413
9414 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
9415 <oslsachem@gmail.com> for helping to debug this.
9416
9417 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
9418 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
9419 (g_b_init_get_glyph_outline_w): New static variables.
9420 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
9421 (GetGlyphOutlineW_Proc): New typedefs.
9422 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
9423 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
9424 New functions.
9425 (w32font_open_internal, compute_metrics):
9426 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
9427 instead of calling the "wide" APIs directly.
9428
9429 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
9430
9431 * w32.h (syms_of_w32font): Add prototype.
9432
9433 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9434

9436 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
9437 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
9438 (Fmove_to_window_line): Doc fix.
9439
9440 2011-10-27 Chong Yidong <cyd@gnu.org>
9441
9442 * process.c (make_process): Set gnutls_state to NULL.
9443
9444 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
9445 non-NULL, regardless of GNUTLS_INITSTAGE.
9446 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
9447 an error. Set process slots as soon as we allocate them.
9448
9449 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
9450
9451 2011-10-27 Chong Yidong <cyd@gnu.org>
9452
9453 * gnutls.c (emacs_gnutls_deinit): New function.
9454 Deallocate credentials structures as well as calling gnutls_deinit.
9455 (Fgnutls_deinit, Fgnutls_boot): Use it.
9456
9457 * process.c (make_process): Initialize GnuTLS credentials to NULL.
9458 (deactivate_process): Call emacs_gnutls_deinit.
9459
9460 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
9461
9462 * image.c (x_create_x_image_and_pixmap):
9463 * w32.c (sys_rename, w32_delayed_load):
9464 * w32font.c (fill_in_logfont):
9465 * w32reg.c (x_get_string_resource): Silence compiler warnings.
9466
9467 2011-10-26 Juanma Barranquero <lekktu@gmail.com>

9470 extracted from Fw32_default_color_map.
9471 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
9472
9473 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
9474
9475 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
9476
9477 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
9478
9479 * keyboard.c (test_undefined): New function (bug#9751).

9481
9482 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
9483
9484 * sysdep.c (init_sys_modes): Fix the check for the controlling
9485 terminal (Bug#6649).
9486
9487 2011-10-20 Eli Zaretskii <eliz@gnu.org>
9488
9489 * dispextern.h (struct bidi_it): New member next_en_type.
9490
9491 * bidi.c (bidi_line_init): Initialize the next_en_type member.
9492 (bidi_resolve_explicit_1): When next_en_pos is valid for the
9493 current character, check also for next_en_type being WEAK_EN.
9494 (bidi_resolve_weak): Don't enter the expensive loop if the current
9495 position is before next_en_pos. Record the bidi type of the first
9496 non-ET, non-BN character we find, in addition to its position.
9497 (bidi_level_of_next_char): Invalidate next_en_type when
9498 next_en_pos is over-stepped.
9499
9500 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
9501
9502 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
9503 * editfns.c: Rewrite current-time-zone so that it invokes
9504 the equivalent of (format-time-string "%Z") to get the time zone name.
9505 This fixes a bug when the time zone name contains characters that
9506 need converting from the system time locale to Emacs internal format.
9507 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
9508 that patch fixed format-time-string to do the conversion, but
9509 I forgot to fix current-time-zone.
9510 (format_time_string): New function, containing most of
9511 what Fformat_time_string used to contain.
9512 (Fformat_time_string): Rewrite in terms of format_time_string.
9513 This doesn't change this function's behavior.
9514 (current-time-zone): Rewrite to use format_time_string.
9515 This fixes the bug reported by Michael Schierl in
9516 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
9517 Jason Rumney's 2007-06-07 change worked around this bug, but
9518 didn't fix it.
9519 * systime.h (tzname, timezone): Remove no-longer-used declarations.
9520
9521 2011-10-19 Eli Zaretskii <eliz@gnu.org>
9522
9523 * xdisp.c (start_display): If the character at POS is displayed
9524 via a display vector, reset IT->current.dpvec_index to zero.
9525 (try_window_reusing_current_matrix): If a line ends in a display
9526 vector or the next line starts in a display vector, continue
9527 redrawing the window even though the character position of
9528 start_row was reached.
9529 (Bug#9771, part 2)
9530
9531 2011-10-18 Chong Yidong <cyd@gnu.org>
9532
9533 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
9534 with nobreak-char-display too.
9535
9536 2011-10-18 Eli Zaretskii <eliz@gnu.org>
9537
9538 Fix part 3 of bug#9771.
9539 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
9540 (bidi_resolve_neutral): Don't enter the expensive loop looking for
9541 non-neutral characters if the current character is a paragraph
9542 separator (a.k.a. Newline). This avoids running the same
9543 expensive loop twice, once when we consume the preceding newline
9544 and the other time when the line actually needs to be displayed.
9545 Avoid the loop when we see neutrals on the base embedding level
9546 following a character whose directionality is the same as the
9547 paragraph's. This avoids running the expensive loop when a line
9548 ends in a long sequence of neutrals, like control characters.
9549 Add assertion against STRONG_AL type. Slightly rearrange code
9550 that determines the type of a neutral given the first non-neutral
9551 that follows it.
9552 (bidi_level_of_next_char): Set next_en_pos to zero when
9553 invalidating its info.
9554
9555 2011-10-17 Eli Zaretskii <eliz@gnu.org>
9556
9557 * xdisp.c (push_display_prop): Determine whether to record string
9558 or buffer position by IT->string, not by IT->method. Allow
9559 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
9560 (move_it_vertically_backward): Don't look for character position
9561 immediately after the newline when in a continuation line.
9562 (Bug#9771, part 1)
9563
9564 2011-10-15 Martin Rudalics <rudalics@gmx.at>
9565
9566 * window.c (coordinates_in_window): Rewrite and delabelize
9567 vertical border check. (Bug#5357) (Bug#9618)
9568
9569 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
9570
9571 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
9572 errors in XSetWindowBorder (bug#9310).
9573
9574 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
9575
9576 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
9577 avoid crash when xmalloc overrun checking is enabled.
9578
9579 2011-10-13 Eli Zaretskii <eliz@gnu.org>
9580
9581 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
9582 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
9583 cursor motion with <left> and <right> arrow keys.
9584
9585 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
9586 some callers set that themselves.
9587
9588 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9589
9590 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
9591 display string and the previous row comes from the same string and
9592 is empty. (Bug#9739) (Bug#9738)
9593
9594 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
9595
9596 * doc.c (get_doc_string): Encode file name (bug#9735).
9597
9598 2011-10-12 Eli Zaretskii <eliz@gnu.org>
9599
9600 * bidi.c (bidi_level_of_next_char):
9601 * xdisp.c (get_visually_first_element): Remove old incorrect
9602 comments regarding the Unicode Line Separator character.
9603
9604 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
9605
9606 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
9607
9608 * alloc.c (Fgc_status): Do not access beyond zombies array
9609 boundary if nzombies > MAX_ZOMBIES.
9610 * alloc.c (dump_zombies): Add missing format specifier.
9611
9612 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
9613
9614 * xdisp.c (set_cursor_from_row): Simplify conditionals,
9615 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
9616
9617 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
9618 Some packages use them to denote characters with modifiers.
9619
9620 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
9621
9622 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
9623 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
9624 matching a pp-number. Rename parameter var to var1.
9625
9626 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
9627
9628 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
9629
9630 2011-10-08 Glenn Morris <rgm@gnu.org>
9631
9632 * callint.c (Fcall_interactively): Give a more explicit error for the
9633 'c' case with a non-character input. (Bug#8479)
9634
9635 2011-10-08 Eli Zaretskii <eliz@gnu.org>
9636
9637 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
9638 lines.
9639 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
9640 lines that are hscrolled on the left.
9641
9642 * dispnew.c (buffer_posn_from_coords): Account for a possible
9643 presence of header-line. (Bug#4426)
9644
9645 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
9646
9647 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
9648 Don't advertise functionality which we discourage or doesn't work.
9649
9650 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
9651
9652 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
9653 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
9654 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
9655 this makes Emacs dump core during garbage collection on rare
9656 occasions. sizeof is obviously inferior to offsetof here, so
9657 stick with offsetof.
9658 (GC_POINTER_ALIGNMENT): New macro.
9659 (mark_memory): Omit 3rd (offset) arg; caller changed.
9660 Don't assume EMACS_INT alignment is the same as pointer alignment.
9661
9662 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
9663
9664 * keyboard.c (read_key_sequence_remapped): New var.
9665 (read_key_sequence): Compute remapping in the right buffer.
9666 (command_loop_1): Use read_key_sequence's remapping directly.
9667
9668 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
9669
9670 * dired.c (file_name_completion): Don't expand file name.
9671 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
9672 before checking file name handler.
9673
9674 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
9675 they've been requested explicitly (bug#9591).
9676
9677 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
9678
9679 * keymap.c (Fsingle_key_description): Use make_specified_string
9680 instead of build_string to build string from push_key_description.
9681 (Bug#5193)
9682
9683 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9684
9685 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
9686 This fixes a Y2038 bug on 64-bit hosts.
9687 * buffer.c (reset_buffer):
9688 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
9689 (Fclear_buffer_auto_save_failure):
9690 Use 0, not -1, to represent an unset failure time, since time_t
9691 might not be signed.
9692
9693 Remove dependency on glibc malloc internals.
9694 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9695 Move back here from lisp.h, but with their new implementations.
9696 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9697 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
9698 * charset.c (charset_table_init): New static var.
9699 (syms_of_charset): Use it instead of xmalloc. This removes a
9700 dependency on glibc malloc internals. See Eli Zaretskii's comment in
9701 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
9702 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9703 Move back to alloc.c.
9704 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9705 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
9706
9707 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
9708
9709 * nsterm.m (windowDidResize): Call x_set_window_size only when
9710 ns_in_resize is true. Otherwise set pixelwidth/height and
9711 call change_frame_size (Bug#9628).
9712
9713 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
9714
9715 Port --enable-checking=all to Fedora 14 x86-64.
9716 * charset.c (syms_of_charset): Also account for glibc malloc's
9717 internal overhead when calculating the initial malloc maximum.
9718
9719 Port --enable-checking=all to Fedora 14 x86.
9720 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9721 Move to lisp.h.
9722 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
9723 (overrun_check_realloc, overrun_check_free):
9724 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
9725 That way, xmalloc returns a properly-aligned pointer even if
9726 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
9727 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
9728 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
9729 into account when calculating the initial malloc maximum.
9730 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
9731 Move here from alloc.c, so that charset.c can use it too.
9732 Properly align; the old code wasn't right for common 32-bit hosts
9733 when configured with --enable-checking=all.
9734 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
9735 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
9736
9737 2011-09-29 Eli Zaretskii <eliz@gnu.org>
9738
9739 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,

9756
9757 * xdisp.c (handle_invisible_prop): If invisible text ends on a

9759 character at a time. (Bug#9610)
9760 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
9761 TO_CHARPOS if the bidi iterator is at base embedding level.

9797 * indent.c (Fvertical_motion): Compute and apply the overshoot
9798 logic when moving up, not only when moving down. Fix the

9800 logic changes accordingly. (Bug#9254) (Bug#9549)
9801

9816 do not ignore write error for any output size
9817 The previous change was incomplete.
9818 While it makes emacs --batch detect the vast majority of stdout
9819 write failures, errors were still ignored whenever the output size is
9820 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
9821 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
9822 && echo FAIL: ignored write error
9823 FAIL: ignored write error
9824 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
9825 && echo FAIL: ignored write error
9826 FAIL: ignored write error
9827 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
9828
9829 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>

9843
9844 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
9845 a display string, extend search for cursor position to end of row.
9846 (find_row_edges): If the row ends in a newline from a display
9847 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
9848 Handle the case of a display string with multiple newlines.
9849 (Fcurrent_bidi_paragraph_direction): Fix search for previous
9850 non-empty line. Fixes confusing cursor motion with arrow keys at

9864
9865 * xdisp.c (display_line): Record maximum and minimum buffer
9866 positions even if no glyphs were produced (e.g., by a zero-width
9867 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
9868 buffer positions that will be removed from the glyph row because
9869 they don't fit.
9870 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
9871 column is beyond frame width: don't subtract 1 "pixel" when
9872 computing width of the stretch.
9873 (reseat_at_next_visible_line_start): Undo the change made on
9874 2011-09-17 that saved paragraph information and restored it after
9875 the call to `reseat'. (Bug#9545)

9896
9897 * fileio.c: Report proper errno when syscall falls.
9898 (Finsert_file_contents): Save and restore errno,
9899 so that report_file_error outputs the correct diagnostic.

9916 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
9917 (bidi_find_paragraph_start): Search back for paragraph beginning
9918 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
9919 (bidi_move_to_visually_next): Only trigger paragraph-related
9920 computations when the last character is a newline or at EOB, not
9921 just any NEUTRAL_B. (Bug#9470)
9922
9923 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
9924 truncated lines if point is covered by a display string. (Bug#9524)

9929 (cons_to_x_long): New function.
9930 (lisp_data_to_selection_data): Use it. Correct the test for

9932 loop, for efficiency, when a long datum is discovered.
9933
9934 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>

9984
9985 * xselect.c: Use signed conversions more consistently (Bug#9498).
9986 (selection_data_to_lisp_data): Assume incoming selection data are
9987 signed integers, not unsigned. This is to be consistent with
9988 outgoing selection data, which was modified to use signed integers
9989 in as part of the fix to Bug#9196 in response to Jan D.'s comment
9990 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
9991 expects long, not unsigned long.

10025
10026 2011-09-11 Eli Zaretskii <eliz@gnu.org>
10027
10028 * fileio.c (Finsert_file_contents): If the file cannot be opened,
10029 set its "size" to -1. This will set the modtime_size field of
10030 the corresponding buffer to -1, which is what
10031 verify-visited-file-modtime expects for files that do not exist.

10035
10036 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
10037 here ...
10038 * lisp.h: ... from here. push_key_description is no longer
10039 defined in keyboard.c, so its declaration should not be in
10040 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
10041 logically belongs with push_key_description.
10042
10043 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
10044
10045 * buffer.h: Include <sys/types.h> instead of <time.h>.

10088 isnan: Fix porting problem to Solaris 10 with bundled gcc.
10089 Without this fix, the command to link temacs failed due to an
10090 undefined symbol __builtin_isnan. This is because
10091 /usr/include/iso/math_c99.h #defines isnan(x) to
10092 __builtin_isnan(x), but the bundled gcc, which identifies itself
10093 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
10094 a __builtin_isnan.
10095 * floatfns.c (isnan): #undef, and then #define to a clone of
10096 what's in data.c.
10097 (Fisnan): Always define, since it's always available now.
10098 (syms_of_floatfns): Always define isnan at the Lisp level.
10099
10100 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10101

10103
10104 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
10105
10106 * fileio.c: Fix bugs with large file offsets (Bug#9428).
10107 The previous code assumed that file offsets (off_t values) fit in
10108 EMACS_INT variables, which is not true on typical 32-bit hosts.
10109 The code messed up by falsely reporting buffer overflow in cases
10110 such as (insert-file-contents "big" nil 1 2) into an empty buffer
10111 when "big" contains more than 2**29 bytes, even though this
10112 inserts just one byte and does not overflow the buffer.
10113 (Finsert_file_contents): Store file offsets as off_t
10114 values, not as EMACS_INT values. Check for overflow when
10115 converting between EMACS_INT and off_t. When checking for
10116 buffer overflow or for overlap, take the offsets into account.
10117 Don't use EMACS_INT for small values where int suffices.
10118 When checking for overlap, fix a typo: ZV was used where
10119 ZV_BYTE was intended.
10120 (Fwrite_region): Don't assume off_t fits into 'long'.
10121 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
10122
10123 2011-09-05 Michael Albinus <michael.albinus@gmx.de>

10130
10131 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
10132 (esprintf, exprintf, evxprintf): New functions.
10133 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
10134 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
10135 (modify_event_symbol): Do not assume that the length of
10136 name_alist_or_stem is safe to alloca and fits in int.
10137 (Fexecute_extended_command): Likewise for function name and binding.
10138 (Frecursion_depth): Wrap around reliably on integer overflow.
10139 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
10140 since some callers pass EMACS_INT values.
10141 (Fsingle_key_description): Don't crash if symbol name contains more
10142 than MAX_ALLOCA bytes.
10143 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
10144 (get_minibuffer): Arg is now EMACS_INT, not int.
10145 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
10146 (esprintf, exprintf, evxprintf): New decls.

10148
10149 * dbusbind.c (signature_cat): New function.
10150 (xd_signature, Fdbus_register_signal):
10151 Do not overrun buffer; instead, report string overflow.
10152
10153 * dispnew.c (add_window_display_history): Don't overrun buffer.
10154 Truncate instead; this is OK since it's just a log.
10155
10156 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
10157 even if the time zone offset is outlandishly large.
10158 Don't mishandle offset == INT_MIN.
10159
10160 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
10161 when creating daemon; the previous buffer-overflow check was incorrect.
10162
10163 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
10164 which has the guts of the old verror function.
10165
10166 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
10167 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
10168
10169 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
10170 (font_unparse_xlfd): Don't blindly alloca long strings.
10171 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
10172 fits in int, when using sprintf. Use single snprintf to count
10173 length of string rather than counting it via multiple sprintfs;
10174 that's simpler and more reliable.
10175 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
10176 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
10177 sprintf, in case result does not fit in int.
10178
10179 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
10180 (fontset_from_font): Print it.
10181
10182 * frame.c (tty_frame_count): Now printmax_t, not int.
10183 (make_terminal_frame, set_term_frame_name): Print it.
10184 (x_report_frame_params): In X, window IDs are unsigned long,
10185 not signed long, so print them as unsigned.
10186 (validate_x_resource_name): Check for implausibly long names,
10187 and don't assume name length fits in 'int'.
10188 (x_get_resource_string): Don't blindly alloca invocation name;
10189 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
10190 not fit in int.
10191
10192 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
10193 (xg_check_special_colors, xg_set_geometry):
10194 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
10195
10196 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
10197 Use esprintf, not sprintf, in case result does not fit in int.
10198
10199 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10200 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
10201 it as a large positive number.
10202 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
10203 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
10204
10205 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
10206 in case result does not fit in int.
10207
10208 * print.c (float_to_string): Detect width overflow more reliably.
10209 (print_object): Make sprintf buffer a bit bigger, to avoid potential
10210 buffer overrun. Don't assume list length fits in 'int'. Treat
10211 print length of 0 as 0, not as infinity; to be consistent with other
10212 uses of print length in this function. Don't overflow print length
10213 index. Don't assume hash table size fits in 'long', or that
10214 vectorlike size fits in 'unsigned long'.
10215
10216 * process.c (make_process): Use printmax_t, not int, to format
10217 process-name gensyms.
10218
10219 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
10220
10221 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
10222 to avoid potential buffer overrun.
10223
10224 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
10225 if X resource line is longer than 512 bytes.
10226
10227 * xfns.c (x_window): Make sprintf buffer a bit bigger
10228 to avoid potential buffer overrun.
10229
10230 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
10231
10232 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
10233
10234 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
10235
10236 Integer overflow fixes for scrolling, etc.
10237 Without these, Emacs silently mishandles large integers sometimes.
10238 For example, "C-u 4294967297 M-x recenter" was treated as if
10239 it were "C-u 1 M-x recenter" on a typical 64-bit host.
10240
10241 * xdisp.c (try_window_id): Check Emacs fixnum range before
10242 converting to 'int'.
10243
10244 * window.c (window_scroll_line_based, Frecenter):
10245 Check that an Emacs fixnum is in range before assigning it to 'int'.
10246 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
10247 values converted from Emacs fixnums.
10248 (Frecenter): Don't wrap around a line count if it is out of 'int'
10249 range; instead, treat it as an extreme value.
10250 (Fset_window_configuration, compare_window_configurations):
10251 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
10252
10253 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
10254 that can exceed INT_MAX. Check that EMACS_INT value is in range
10255 before assigning it to the (possibly-narrower) index.
10256 (match_limit): Don't assume that a fixnum can fit in 'int'.
10257
10258 * print.c (print_object): Use ptrdiff_t, not int, for index that can
10259 exceed INT_MAX.
10260
10261 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
10262 (Fvertical_motion): Don't wrap around LINES values that don't fit
10263 in 'int'. Instead, treat them as extreme values. This is good
10264 enough for windows, which can't have more than INT_MAX lines anyway.
10265
10266 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
10267
10268 * Require libxml/parser.h to avoid compilation warning.
10269
10270 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
10271
10272 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
10273 since this reportedly can destroy thread storage.
10274
10275 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
10276
10277 * syntax.c (find_defun_start): Update all cache variables if
10278 exiting early (Bug#9401).
10279
10280 2011-08-30 Eli Zaretskii <eliz@gnu.org>
10281
10282 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
10283
10284 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
10285 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
10286 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
10287
10288 * term.c (tty_append_glyph): New function.
10289 (produce_stretch_glyph): Static function and its prototype deleted.
10290
10291 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
10292 Add prototypes.
10293
10294 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
10295
10296 * image.c (parse_image_spec): Check for nonnegative, not for positive,
10297 when checking :margin (Bug#9390).
10298 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
10299 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
10300 so that the name doesn't mislead. All uses changed.
10301
10302 2011-08-28 Johan Bockgård <bojohan@gnu.org>
10303
10304 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
10305 set_tty_hooks.
10306
10307 2011-08-27 Eli Zaretskii <eliz@gnu.org>
10308
10309 * xdisp.c (move_it_to): Don't bail out early when reaching
10310 position beyond to_charpos, if we are scanning backwards.
10311 (move_it_vertically_backward): When DY == 0, make sure we get to
10312 the first character in the line after the newline.
10313
10314 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
10315
10316 * ccl.c: Improve and simplify overflow checking (Bug#9196).
10317 (ccl_driver): Do not generate an out-of-range pointer.
10318 (Fccl_execute_on_string): Remove unnecessary check for
10319 integer overflow, noted by Stefan Monnier in
10320 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
10321 Remove a FIXME that didn't need fixing.
10322 Simplify the newly-introduced buffer reallocation code.
10323
10324 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
10325
10326 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
10327
10328 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
10329
10330 Integer and memory overflow issues (Bug#9196).
10331
10332 * doc.c (get_doc_string): Rework so that
10333 get_doc_string_buffer_size is the actual buffer size, rather than
10334 being 1 less than the actual buffer size; this makes xpalloc more
10335 convenient.
10336
10337 * image.c (x_allocate_bitmap_record, cache_image):
10338 * xselect.c (Fx_register_dnd_atom):
10339 Simplify previous changes by using xpalloc.
10340
10341 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
10342 since either will do and ptrdiff_t is convenient with xpalloc.
10343
10344 * charset.c (charset_table_size)
10345 (struct charset_sort_data.priority): Now ptrdiff_t.
10346 (charset_compare): Don't overflow if priorities differ greatly.
10347 (Fsort_charsets): Don't assume list length fits in int.
10348 Check for size-calculation overflow when allocating sort data.
10349 (syms_of_charset): Allocate an initial charset table that is
10350 just under 64 KiB, to avoid problems with glibc malloc and mmap.
10351
10352 * cmds.c (internal_self_insert): Check for size-calculation overflow.
10353
10354 * composite.h (struct composition.glyph_len): Now int, not unsigned.
10355 The actual value is always <= INT_MAX, and leaving it unsigned made
10356 overflow checking harder.
10357
10358 * dispextern.h (struct glyph_matrix.rows_allocated)
10359 (struct face_cache.size): Now ptrdiff_t, for convenience in use
10360 with xpalloc. The values are still always <= INT_MAX.
10361
10362 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
10363
10364 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
10365 (SAFE_NALLOCA): New macro.
10366
10367 * region-cache.c (struct boundary.pos, find_cache_boundary)
10368 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
10369 (set_cache_region, invalidate_region_cache)
10370 (revalidate_region_cache, know_region_cache, region_cache_forward)
10371 (region_cache_backward, pp_cache):
10372 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
10373 so that ptrdiff_t * can be passed to xpalloc.
10374 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
10375 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
10376 (pp_cache): Don't assume cache_len fits in int.
10377 * region-cache.h: Adjust extern decls to match.
10378
10379 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
10380 EMACS_INT, since either will do, for xpalloc.
10381
10382 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
10383 (xnmalloc, xnrealloc, xpalloc): New functions.
10384
10385 * bidi.c (bidi_shelve_header_size): New constant.
10386 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
10387 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
10388
10389 * bidi.c (bidi_cache_shrink):
10390 * buffer.c (overlays_at, overlays_in, record_overlay_string)
10391 (overlay_strings):
10392 Don't update size of array until after memory allocation succeeds,
10393 because xmalloc/xrealloc may not return.
10394 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
10395 now that we have proper integer overflow checking.
10396 (record_overlay_string, overlay_strings): Catch overflows when
10397 calculating size of overlay_str_buf.
10398
10399 * callproc.c (Fcall_process): Check for size overflow when
10400 calculating size of args2.
10401 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
10402 Normally we prefer signed values, but sticking with ptrdiff_t would
10403 require adding more-complicated checks.
10404
10405 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
10406 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
10407 Redo buffer-overflow calculations to avoid integer overflow.
10408 Add a FIXME comment where memory seems to be over-allocated.
10409
10410 * character.c (Fstring): Check for size-calculation overflow.
10411
10412 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
10413 unnecessary integer overflow. Check for size overflow.
10414 (encode_coding_object): Don't update size until xmalloc succeeds.
10415
10416 * composite.c (get_composition_id): Check for overflow in glyph
10417 length calculations.
10418
10419 Integer and memory overflow fixes for display code.
10420 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
10421 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
10422 (scrolling_window): Check for overflow in size calculations.
10423 (line_draw_cost, realloc_glyph_pool, add_row_entry):
10424 Don't assume glyph table len fits in int.
10425 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
10426 (row_table_size): Now ptrdiff_t, not int.
10427 (scrolling_window): Avoid overflow in size calculations.
10428 Don't update size until allocation succeeds.
10429 * fns.c (concat): Check for overflow in size calculations.
10430 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
10431 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
10432 (NEXT_ALMOST_PRIME_LIMIT): New constant.
10433
10434 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
10435 (get_doc_string): Check for size calculation overflow.
10436 Don't update size until allocation succeeds.
10437 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
10438 EMACS_INT, where ptrdiff_t will do.
10439 (Fsubstitute_command_keys): Check for string overflow.
10440
10441 * editfns.c (set_time_zone_rule): Don't assume environment length
10442 fits in int.
10443 (message_length): Now ptrdiff_t, not int.
10444 (Fmessage_box): Don't update size until allocation succeeds.
10445 Don't assume message length fits in int.
10446 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
10447
10448 * emacs.c (main): Do not reallocate argv, since there is a null at
10449 the end that can be overwritten, and this way there's no need to
10450 worry about size-calculation overflow.
10451 (sort_args): Check for size-calculation overflow.
10452
10453 * eval.c (init_eval_once, grow_specpdl): Don't update size until
10454 alloc succeeds.
10455 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
10456
10457 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
10458 (x_set_scroll_bar_width, x_figure_window_size):
10459 Check for integer overflow.
10460 (x_set_alpha): Do not assume XINT fits in int.
10461
10462 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10463 This is for the members text_lines, text_cols, total_lines, total_cols,
10464 where the system imposes an 'int' limit.
10465
10466 * fringe.c (Fdefine_fringe_bitmap):
10467 Don't update size until alloc works.
10468
10469 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
10470 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
10471
10472 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
10473 Check for size-calculation overflow.
10474 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
10475 do, as we prefer signed integers.
10476 (id_to_widget.max_size, id_to_widget.used)
10477 (xg_store_widget_in_map, xg_remove_widget_from_map)
10478 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
10479 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
10480 Use and return ptrdiff_t, not int.
10481 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
10482 * gtkutil.h: Change prototypes to match the above.
10483
10484 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
10485 are duplicate now that they've been promoted to lisp.h.
10486 (x_allocate_bitmap_record, x_alloc_image_color)
10487 (make_image_cache, cache_image, xpm_load):
10488 Don't update size until alloc is done.
10489 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
10490 (x_detect_edges):
10491 Check for size calculation overflow.
10492 (ct_colors_allocated_max): New constant.
10493 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
10494 overflow.
10495
10496 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
10497 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
10498 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
10499 Use ptrdiff_t, not int, to count maps.
10500 (read_char_minibuf_menu_prompt): Check for overflow in size
10501 calculations. Don't update size until allocation succeeds.
10502 Redo calculations to avoid overflow.

10524
10525 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
10526 overflow. Don't bother calling xmalloc when xrealloc will do.
10527
10528 * search.c (Freplace_match): Check for size calculation overflow.
10529 (Fset_match_data): Don't assume list lengths fit in 'int'.
10530
10531 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
10532 for command line length. Do not attempt to address one before the
10533 beginning of an array, as that's not portable.
10534
10535 * term.c (max_frame_lines): Remove; unused.
10536 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
10537 not int.
10538 (encode_terminal_code, calculate_costs): Check for size
10539 calculation overflow.
10540 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
10541 table lengths and related sizes. Don't update size until alloc
10542 done. Redo calculations to avoid overflow.
10543 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
10544
10545 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
10546 subtracting pointers.
10547 (gobble_line): Check for overflow more carefully. Don't update size
10548 until alloc done.
10549
10550 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
10551 Don't update size until alloc done.
10552 Redo size calculations to avoid overflow.

10557 Use ptrdiff_t, not int, for sizes.
10558 (store_mode_line_noprop_char): Don't update size until alloc done.
10559
10560 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
10561 Use ptrdiff_t, not int, for sizes.
10562 (Finternal_make_lisp_face, cache_face):
10563 Check for size calculation overflow.
10564 (cache_face): Treat size calculation overflows as if they were
10565 memory exhaustion (the usual treatment), rather than aborting.
10566
10567 * xfns.c (x_encode_text, x_set_name_internal)
10568 (Fx_change_window_property): Use ptrdiff_t, not int, to count
10569 sizes, since they can exceed INT_MAX in size. Check for size
10570 calculation overflow.
10571
10572 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
10573 (xg_select): Check for size calculation overflow.
10574 Don't update size until alloc done.
10575
10576 * xrdb.c (get_environ_db): Don't assume path length fits in int,
10577 as sprintf is limited to int lengths.
10578
10579 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
10580 (X_LONG_MIN): New macros.
10581 Use them to make the following changes clearer.
10582 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
10583 This change doesn't affect the value now, but it may help remind
10584 future maintainers not to raise the value too much later.
10585 (SELECTION_QUANTUM): Remove, replacing with ...
10586 (selection_quantum): ... new function, which avoids overflow.
10587 All uses changed.
10588 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
10589 assumption that selection length fits in 'int'.
10590 (x_reply_selection_request, x_handle_selection_request)
10591 (x_get_window_property, receive_incremental_selection)
10592 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
10593 (lisp_data_to_selection_data, clean_local_selection_data):
10594 Use ptrdiff_t, not int, to record length of selection.
10595 (x_reply_selection_request, x_get_window_property)
10596 (receive_incremental_selection, x_property_data_to_lisp):
10597 Redo calculations to avoid overflow.
10598 (x_reply_selection_request): When sending hint, ceiling it at
10599 X_LONG_MAX rather than relying on wraparound overflow to send
10600 something.
10601 (x_get_window_property, receive_incremental_selection)
10602 (lisp_data_to_selection_data, x_property_data_to_lisp):
10603 Check for size-calculation overflow.
10604 (x_get_window_property, receive_incremental_selection)
10605 (lisp_data_to_selection_data, Fx_register_dnd_atom):
10606 Don't store size until memory allocation succeeds.
10607 (x_get_window_property): Plug memory leak on memory exhaustion.
10608 Don't double-block input; malloc is safe here. Don't assume 2**34
10609 - 4 fits in unsigned long. Add an xassert to check
10610 XGetWindowProperty overflow. Be more careful about overflow
10611 calculations, and distinguish size from memory overflow better.
10612 (receive_incremental_selection): When tracing, don't assume
10613 unsigned int is less than INT_MAX.
10614 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
10615 harmful) conversions of unsigned short to int.
10616 (lisp_data_to_selection_data): Don't assume that integers
10617 in the range -65535 through -1 fit in an X unsigned short.
10618 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
10619 result parameters unless successful. Rely on cons_to_unsigned
10620 to report problems with elements; the old code wasn't right anyway.
10621 (x_check_property_data): Check for int overflow; we cannot use
10622 a wider type due to X limits.
10623 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
10624
10625 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
10626
10627 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
10628 (x_term_init): Check for size calculation overflow.
10629 (x_color_cells): Don't store size until memory allocation succeeds.

10631 Don't assume alloca size is less than MAX_ALLOCA.
10632 (x_term_init): Don't assume length fits in int (sprintf is limited
10633 to int size).
10634
10635 Use ptrdiff_t for composition IDs.
10636 * character.c (lisp_string_width):
10637 * composite.c (composition_table_size, n_compositions)
10638 (get_composition_id, composition_gstring_from_id):

10642 Use ptrdiff_t, not int, for composition IDs.
10643 * composite.c (get_composition_id): Check for integer overflow.
10644 * composite.h: Adjust prototypes to match the above changes.
10645

10654 * image.c (xpm_get_color_table_h):
10655 * lisp.h (hash_lookup, hash_put):
10656 * minibuf.c (Ftest_completion):
10657 Use ptrdiff_t for hash table indexes, not int (which is too
10658 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
10659 32-bit --with-wide-int hosts).
10660
10661 * charset.c (Fdefine_charset_internal): Check for integer overflow.
10662 Add a FIXME comment about memory leaks.
10663 (syms_of_charset): Don't assume xmalloc returns.
10664
10665 Don't assume that stated character widths fit in int.
10666 * character.c (Fchar_width, c_string_width, lisp_string_width):
10667 * character.h (CHAR_WIDTH):
10668 * indent.c (MULTIBYTE_BYTES_WIDTH):
10669 Use sanitize_char_width to avoid undefined and/or bad behavior
10670 with outlandish widths.
10671 * character.h (sanitize_tab_width): Rename from sanitize_width,
10672 now that we have two such functions. All uses changed.
10673 (sanitize_char_width): New inline function.
10674
10675 Don't assume that tab-width fits in int.
10676 * character.h (sanitize_width): New inline function.
10677 (SANE_TAB_WIDTH): New macro.
10678 (ASCII_CHAR_WIDTH): Use it.
10679 * indent.c (sane_tab_width): Remove. All uses replaced by
10680 SANE_TAB_WIDTH (current_buffer).
10681 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
10682
10683 * fileio.c: Integer overflow issues with file modes.
10684 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
10685
10686 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
10687 Remove unreachable code.
10688 (read_hex, load_charset_map_from_file): Check for integer overflow.
10689
10690 * xterm.c: Don't go over XClientMessageEvent limit.
10691 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
10692 (x_send_scroll_bar_event): Likewise. Check that the size does not
10693 exceed limits imposed by XClientMessageEvent, as well as the usual
10694 ptrdiff_t and size_t limits.
10695
10696 * keyboard.c: Overflow, signedness and related fixes.
10697 (make_lispy_movement): Use same integer type in forward decl
10698 that is used in the definition.
10699 (read_key_sequence, keyremap_step):
10700 Change bufsize argument back to int, undoing my 2011-03-30 change.
10701 We prefer signed types, and int is wide enough here.
10702 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
10703 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
10704 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
10705 length, not size_t. Use ptrdiff_t for index, not int.
10706 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
10707 possibility of integer overflow.
10708
10709 Overflow, signedness and related fixes for images.

10719 * xdisp.c (calc_pixel_width_or_height):
10720 * xfns.c (image_cache_refcount):
10721 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
10722 on typical 64-bit hosts.
10723
10724 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
10725 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
10726 Omit unnecessary casts to int.
10727 (parse_image_spec): Check that integers fall into 'int' range
10728 when the callers expect that.
10729 (image_ascent): Redo ascent calculation to avoid int overflow.
10730 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
10731 (lookup_image): Remove unnecessary tests.
10732 (xbm_image_p): Locals are now of int, not EMACS_INT,
10733 since parse_image_check makes sure they fit into int.
10734 (png_load, gif_load, svg_load_image):
10735 Prefer int to unsigned where either will do.
10736 (tiff_handler): New function, combining the cores of the
10737 old tiff_error_handler and tiff_warning_handler.
10738 This function is rewritten to use vsnprintf and thereby avoid
10739 stack buffer overflows. It uses only the features of vsnprintf
10740 that are common to both POSIX and native Microsoft.
10741 (tiff_error_handler, tiff_warning_handler): Use it.
10742 (tiff_load, gif_load, imagemagick_load_image):
10743 Don't assume :index value fits in 'int'.
10744 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
10745 (imagemagick_load_image): Check that crop parameters fit into
10746 the integer types that MagickCropImage accepts. Don't assume
10747 Vimagemagick_render_type has a nonnegative value. Don't assume
10748 size_t fits in 'long'.
10749 (gs_load): Use printmax_t to print the widest integers possible.
10750 Check for integer overflow when computing image height and width.
10751
10752 2011-08-26 Eli Zaretskii <eliz@gnu.org>
10753
10754 * xdisp.c (redisplay_window): Don't force window start if point
10755 will be invisible in the resulting window. (Bug#9324)
10756
10757 2011-08-25 Eli Zaretskii <eliz@gnu.org>
10758
10759 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
10760 the display spec is of the form `(space ...)'.
10761 (handle_display_spec): Return the value returned by
10762 handle_single_display_spec, not just 1 or zero.
10763 (handle_single_display_spec): If the display spec is of the form
10764 `(space ...)', and specifies display in the text area, return 2
10765 rather than 1.
10766 (try_cursor_movement): Check for the need to scroll more
10767 accurately, and prefer exact match for point under bidi.
10768 Don't advance `row' beyond the last row of the window.
10769
10770 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
10771 into disp_prop; all users changed.
10772
10773 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
10774 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
10775 for the text covered by the display property.

10786 buffers, return left-to-right.
10787 (set_cursor_from_row): Consider candidate row a win if its glyph
10788 represents a newline and point is on that newline. Fixes cursor
10789 positioning on the newline at EOL of R2L text within L2R
10790 paragraph, and vice versa.
10791 (try_cursor_movement): Check continued rows, in addition to
10792 continuation rows. Fixes unwarranted scroll when point enters a
10793 continued line of R2L text within an L2R paragraph, or vice versa.
10794 (cursor_row_p): Consider the case of point being equal to
10795 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
10796 from the end of a short line to the beginning of a continued line
10797 of R2L text within L2R paragraph.
10798 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
10799 composed characters.
10800
10801 * bidi.c (bidi_check_type): Use xassert.
10802 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
10803 members.

10819 2011-08-23 Eli Zaretskii <eliz@gnu.org>
10820
10821 * xdisp.c (redisplay_window): When computing centering_position,
10822 account for the height of the header line. (Bug#8874)
10823
10824 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
10825 instead of CHAR_TO_BYTE. Fixes a crash when a completion
10826 candidate is selected by the mouse, and that candidate has a
10827 composed character under the mouse.
10828
10829 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
10830 coordinates reported by pos-visible-in-window-p for a composed
10831 character in column zero.
10832
10833 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

10838
10839 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
10840 consider it a hit if to_charpos is anywhere in the range of the
10841 composed buffer positions.
10842
10843 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
10844
10845 * image.c (gif_load): Don't assume that each subimage has the same
10846 dimensions as the base image. Handle disposal method that is
10847 "undefined" by the gif spec (Bug#9335).
10848

10860 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
10861 a composition, take its buffer position from IT->cmp_it.charpos.
10862 Fixes cursor positioning at the beginning of a line that begins
10863 with a composed character.
10864
10865 2011-08-18 Eli Zaretskii <eliz@gnu.org>
10866
10867 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
10868 character bidirectional type, use STRONG_L instead. Fixes crashes
10869 in a buffer produced by `describe-categories'.
10870
10871 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
10872 members before the level stack, so they would be saved and
10873 restored when copying iterator state. Fixes incorrect reordering
10874 around TABs covered by display properties.
10875
10876 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
10877

10956 (NSAPP_DATA2_RUNASSCRIPT): Define.
10957
10958 * nsfns.m (as_script, as_result, as_status): New static variables.
10959 (ns_run_ascript): New function.
10960 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
10961 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
10962 the event loop. Get status from as_status (Bug#7276).
10963
10964 * nsterm.m (sendEvent): If event is NSApplicationDefined and
10965 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
10966 the event loop (Bug#7276).
10967
10968 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
10969
10970 * gnutls.c (QCgnutls_bootprop_priority)
10971 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
10972 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
10973 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
10974 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
10975 (QCgnutls_bootprop_verify_hostname_error)
10976 (QCgnutls_bootprop_callbacks_verify): Rename from
10977 Qgnutls_bootprop_..., all uses changed.
10978
10979 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
10980 uses changed.
10981
10982 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
10983
10984 * xfaces.c (Qframe_set_background_mode): Now static.
10985 * dispextern.h (Qframe_set_background_mode): Remove decl.
10986
10987 * process.c (Fnetwork_interface_info): Declare local only if needed.
10988
10989 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
10990
10991 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
10992 (Fnetwork_interface_list): Allocate in increments of bytes instead
10993 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
10994 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
10995 sockaddr.
10996 (struct ifflag_def): notrailers is smart on OSX.
10997 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
10998 Get hardware address with getifaddrs if available.
10999
11000 2011-08-12 Eli Zaretskii <eliz@gnu.org>
11001
11002 * xdisp.c (iterate_out_of_display_property): xassert that
11003 IT->position is set to within IT->object's boundaries. Break from
11004 the loop as soon as EOB is reached; avoids infloops in redisplay
11005 when IT->position is set up wrongly due to some bug.
11006 Set IT->current to match the bidi iterator unconditionally.
11007 (push_display_prop): Allow GET_FROM_STRING as IT->method on
11008 entry. Force push_it to save on the stack the current
11009 buffer/string position, to be restored by pop_it. Fix flags in
11010 the iterator structure wrt the object coming from a display
11011 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
11012 properties. (Bug#9284)
11013
11014 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
11015
11016 * fontset.c (fontset_get_font_group): Add proper type checks.
11017 (Bug#9172)
11018
11019 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11020
11021 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
11022 and LC_VERSION_MIN_MACOSX.
11023 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
11024 (dump_it) [LC_FUNCTION_STARTS]: Use it.
11025
11026 2011-08-08 Eli Zaretskii <eliz@gnu.org>
11027
11028 * xdisp.c (forward_to_next_line_start): Allow to use the
11029 no-display-properties-and-no-overlays under bidi display.
11030 Set disp_pos in the bidi iterator to avoid searches for display
11031 properties and overlays.
11032
11033 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
11034
11035 * editfns.c (Fset_time_zone_rule): Document relationship with the
11036 setenv function.
11037
11038 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
11039 the font entity extracted from the cache (Bug#8109).
11040
11041 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
11042
11043 * composite.c (autocmp_chars): Don't reset point. That is done by
11044 restore_point_unwind (Bug#5984).
11045
11046 2011-08-07 Juri Linkov <juri@jurta.org>
11047
11048 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
11049 to show the arg `TIME' instead of `TIMEVAL'.
11050
11051 2011-08-06 Eli Zaretskii <eliz@gnu.org>
11052
11053 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
11054 display property strides EOL and includes a newline, as in
11055 longlines-mode. (Bug#9254)
11056 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
11057 word-wrap under bidirectional display. (Bug#9224)
11058
11059 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
11060 is non-zero, even if the data buffer is NULL. Fixes a crash in
11061 vertical-motion with longlines-mode. (Bug#9254)
11062
11063 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11064
11065 * bidi.c <bidi_cache_total_alloc>: Now static.
11066 (bidi_initialize): Initialize bidi_cache_total_alloc.
11067
11068 * xdisp.c (display_line): Release buffer allocated for shelved bidi
11069 cache. (Bug#9221)
11070
11071 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
11072 amount allocated this far in `bidi_cache_total_alloc'.
11073 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
11074 non-zero, only free the data buffer without restoring the cache
11075 contents. All callers changed.
11076
11077 * dispextern.h (bidi_unshelve_cache): Update prototype.
11078
11079 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
11080 (move_it_in_display_line, move_it_to)
11081 (move_it_vertically_backward, move_it_by_lines): Replace the call
11082 to xfree to an equivalent call to bidi_unshelve_cache.
11083 (move_it_in_display_line_to): Fix logic of returning
11084 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
11085
11086 2011-08-05 Eli Zaretskii <eliz@gnu.org>
11087
11088 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
11089 came from a string character with a `cursor' property. (Bug#9229)
11090
11091 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11092
11093 * Makefile.in (LIB_PTHREAD): New variable.
11094 (LIBES): Add LIB_PTHREAD (Bug#9216).
11095
11096 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
11097 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
11098
11099 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
11100
11101 * regex.c (re_iswctype): Remove some redundant boolean conversions.
11102
11103 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
11104
11105 * xterm.c (x_find_topmost_parent): New function.
11106 (x_set_frame_alpha): Find topmost parent window with
11107 x_find_topmost_parent and set the property there also (bug#9181).
11108 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
11109
11110 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
11111
11112 * callproc.c (Fcall_process): Avoid vfork clobbering
11113 the local vars buffer, coding_systems, current_dir.
11114
11115 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
11116
11117 * keymap.c (Fmake_composed_keymap): Move to subr.el.
11118
11119 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
11120
11121 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
11122 so that it is not optimized away.
11123
11124 * xdisp.c (compute_display_string_pos): Remove unused local.
11125
11126 2011-08-02 Eli Zaretskii <eliz@gnu.org>
11127
11128 Fix slow cursor motion and scrolling in large buffers with
11129 selective display, like Org Mode buffers. (Bug#9218)
11130
11131 * dispextern.h (struct bidi_it): New member disp_prop_p.
11132
11133 * xdisp.c: Remove one-slot cache of display string positions.
11134 (compute_display_string_pos): Accept an additional argument
11135 DISP_PROP_P; callers changed. Scan at most 5K characters forward
11136 for a display string or property. If found, set DISP_PROP_P
11137 non-zero.
11138
11139 * bidi.c (bidi_fetch_char): Accept an additional argument
11140 DISP_PROP_P, and pass it to compute_display_string_pos.
11141 Only handle text covered by a display string if DISP_PROP_P is returned
11142 non-zero. All callers of bidi_fetch_char changed.
11143
11144 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
11145
11146 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
11147
11148 2010-12-03 Don March <don@ohspite.net>
11149
11150 * keymap.c (Fdefine_key): Fix non-prefix key error message when
11151 last character M-[char] is translated to ESC [char] (bug#7541).
11152
11153 2011-08-02 Kenichi Handa <handa@m17n.org>
11154
11155 * lisp.h (uniprop_table): Extern it.
11156
11157 * chartab.c (uniprop_table): Make it non-static.
11158
11159 2011-08-01 Eli Zaretskii <eliz@gnu.org>
11160
11161 * xdisp.c (forward_to_next_line_start): Accept additional argument
11162 BIDI_IT_PREV, and store into it the state of the bidi iterator had
11163 on the newline.
11164 (reseat_at_next_visible_line_start): Use the bidi iterator state
11165 returned by forward_to_next_line_start to restore the state of
11166 it->bidi_it after backing up to previous newline. (Bug#9212)
11167
11168 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
11169
11170 * regex.c (re_comp): Protoize.
11171 (re_exec): Fix return type.
11172 (regexec): Fix type of `ret'. (Bug#9203)
11173
11174 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11175
11176 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
11177 This is needed if max-image-size is a floating-point number.
11178
11179 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11180
11181 * print.c (print_object): Print empty symbol as ##.
11182
11183 * lread.c (read1): Read ## as empty symbol.
11184
11185 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11186
11187 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
11188 setting frame foreground color (Bug#9175).
11189 (x_set_background_color): Likewise.
11190
11191 * nsmenu.m (-setText): Size tooltip dimensions precisely to
11192 contents (Bug#9176).
11193 (EmacsTooltip -init): Remove bezels and add shadows to
11194 tooltip windows.
11195
11196 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
11197 or scroll bar (Bug#8470).
11198
11199 * nsfont.m (nsfont_open): Remove assignment to voffset and
11200 unnecessary vars hshink, expand, hd, full_height, min_height.
11201 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
11202
11203 * nsterm.h (nsfont_info): Remove voffset field.
11204
11205 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
11206
11207 Implement strike-through and overline on NextStep (Bug#8863).
11208
11209 * nsfont.m (nsfont_open): Use underline position provided by font,
11210 instead of hard-coded value of 2.
11211 (nsfont_draw): Call ns_draw_text_decoration instead.
11212
11213 * nsterm.h: Add declaration for ns_draw_text_decoration.
11214
11215 * nsterm.m (ns_draw_text_decoration): New function for drawing
11216 underline, overline, and strike-through.
11217 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
11218 ns_draw_text_decoration. Change treatment of cursor drawing to
11219 accommodate underlining, etc.
11220
11221 2011-07-28 Eli Zaretskii <eliz@gnu.org>
11222
11223 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
11224 default.
11225
11226 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11227
11228 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
11229 Without this fix, if a signal arrives just after memory fills up,
11230 'malloc' might be invoked reentrantly.
11231
11232 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
11233 In other words, assume that every image size is allowed, on non-X
11234 hosts. This assumption is probably wrong, but it lets Emacs compile.
11235
11236 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
11237
11238 * regex.c (re_iswctype): Convert return values to boolean.
11239
11240 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
11241
11242 * xdisp.c (compute_display_string_pos): Don't use cached display
11243 string position if the buffer had its restriction changed.
11244 (Bug#9184)
11245
11246 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11247
11248 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11249
11250 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
11251
11252 Integer signedness and overflow and related fixes. (Bug#9079)
11253
11254 * bidi.c: Integer size and overflow fixes.
11255 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
11256 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
11257 (bidi_cache_find_level_change, bidi_cache_ensure_space)
11258 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
11259 (bidi_find_other_level_edge):
11260 Use ptrdiff_t instead of EMACS_INT where either will do.
11261 This works better on 32-bit hosts configured --with-wide-int.
11262 (bidi_cache_ensure_space): Check for size-calculation overflow.
11263 Use % rather than repeated addition, for better worst-case speed.
11264 Don't set bidi_cache_size until after xrealloc returns, because it
11265 might not return.
11266 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
11267 (bidi_cache_ensure_space): Also check that the bidi cache size
11268 does not exceed that of the largest Lisp string or buffer. See Eli
11269 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
11270
11271 * alloc.c (__malloc_size_t): Remove.
11272 All uses replaced by size_t. See Andreas Schwab's note
11273 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
11274
11275 * image.c: Improve checking for integer overflow.
11276 (check_image_size): Assume that f is nonnull, since
11277 it is always nonnull in practice. This is one less thing to
11278 worry about when checking for integer overflow later.
11279 (x_check_image_size): New function, which checks for integer
11280 overflow issues inside X.
11281 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
11282 This removes the need for a memory_full check.
11283 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
11284 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
11285 (xbm_read_bitmap_data): Change locals back to 'int', since
11286 their values must fit in 'int'.
11287 (xpm_load_image, png_load, tiff_load):
11288 Invoke x_create_x_image_and_pixmap earlier,
11289 to avoid much needless work if the image is too large.
11290 (tiff_load): Treat overly large images as if
11291 x_create_x_image_and_pixmap failed, not as malloc failures.
11292 (gs_load): Use x_check_image_size.
11293
11294 * gtkutil.c: Omit integer casts.
11295 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
11296 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
11297
11298 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
11299
11300 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
11301 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
11302 would wrongly return t on a 64-bit host.
11303
11304 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
11305 The plain *_OVERFLOW macros run afoul of GCC bug 49705
11306 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
11307 and therefore cause GCC to emit a bogus diagnostic in some cases.
11308
11309 * image.c: Integer signedness and overflow and related fixes.
11310 This is not an exhaustive set of fixes, but it's time to
11311 record what I've got.
11312 (lookup_pixel_color, check_image_size): Remove redundant decls.
11313 (check_image_size): Don't assume that arbitrary EMACS_INT values
11314 fit in 'int', or that arbitrary 'double' values fit in 'int'.
11315 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
11316 (tiff_load, imagemagick_load_image):
11317 Check for overflow in size calculations.
11318 (x_create_x_image_and_pixmap): Remove unnecessary test for
11319 xmalloc returning NULL; that can't happen.
11320 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
11321 (xpm_color_bucket): Use better integer hashing function.
11322 (xpm_cache_color): Don't possibly over-allocate memory.
11323 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
11324 (gif_memory_source):
11325 Use ptrdiff_t, not int or size_t, to record sizes.
11326 (png_load): Don't assume values greater than 2**31 fit in 'int'.
11327 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
11328 either works, as we prefer signed integers.
11329 (tiff_read_from_memory, tiff_write_from_memory):
11330 Return tsize_t, not size_t, since that's what the TIFF API wants.
11331 (tiff_read_from_memory): Don't fail simply because the read would
11332 go past EOF; instead, return a short read.
11333 (tiff_load): Omit no-longer-needed casts.
11334 (Fimagemagick_types): Don't assume size fits into 'int'.
11335
11336 Improve hashing quality when configured --with-wide-int.
11337 * fns.c (hash_string): New function, taken from sxhash_string.
11338 Do not discard information about ASCII character case; this
11339 discarding is no longer needed.
11340 (sxhash-string): Use it. Change sig to match it. Caller changed.
11341 * lisp.h: Declare it.
11342 * lread.c (hash_string): Remove, since we now use fns.c's version.
11343 The fns.c version returns a wider integer if --with-wide-int is
11344 specified, so this should help the quality of the hashing a bit.
11345
11346 * emacs.c: Integer overflow minor fix.
11347 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
11348 Define only if GNU_LINUX.
11349 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
11350
11351 * dispnew.c: Integer signedness and overflow fixes.
11352 Remove unnecessary forward decls, that were a maintenance hassle.
11353 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
11354 All uses changed.
11355 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
11356 (scrolling_window): Use ptrdiff_t, not int, for byte count.
11357 (prepare_desired_row, line_draw_cost):
11358 Use int, not unsigned, where either works.
11359 (save_current_matrix, restore_current_matrix):
11360 Use ptrdiff_t, not size_t, where either works.
11361 (init_display): Check for overflow more accurately, and without
11362 relying on undefined behavior.
11363
11364 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
11365 Remove, replacing with the new symbols in lisp.h. All uses changed.
11366 * fileio.c (make_temp_name):
11367 * filelock.c (lock_file_1, lock_file):
11368 * xdisp.c (message_dolog):
11369 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
11370 Use pMd etc. instead.
11371 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
11372 replacing the pWIDE etc. symbols removed from editfns.c.
11373
11374 * keyboard.h (num_input_events): Now uintmax_t.
11375 This is (very slightly) less likely to mess up due to wraparound.
11376 All uses changed.
11377
11378 * buffer.c: Integer signedness fixes.
11379 (alloc_buffer_text, enlarge_buffer_text):
11380 Use ptrdiff_t rather than size_t when either will do, as we prefer
11381 signed integers.
11382
11383 * alloc.c: Integer signedness and overflow fixes.
11384 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
11385 (__malloc_size_t): Default to size_t, not to int.
11386 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
11387 (Fgarbage_collect, mark_object_loop_halt, mark_object):
11388 Prefer ptrdiff_t to size_t when either would do, as we prefer
11389 signed integers.
11390 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
11391 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
11392 Now const. Initialize with values that are in range even if char
11393 is signed.
11394 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
11395 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
11396 These functions do the right thing with sizes > 2**32.
11397 (check_depth): Now ptrdiff_t, not int.
11398 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
11399 Adjust to new way of storing sizes. Check for size overflow bugs
11400 in rest of code.
11401 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
11402 slightly wrong anyway, as it missed one instance of
11403 XMALLOC_OVERRUN_CHECK_OVERHEAD.
11404 (refill_memory_reserve): Omit needless cast to size_t.
11405 (mark_object_loop_halt): Mark as externally visible.
11406
11407 * xselect.c: Integer signedness and overflow fixes.
11408 (Fx_register_dnd_atom, x_handle_dnd_message):
11409 Use ptrdiff_t, not size_t, since we prefer signed.
11410 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
11411 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
11412 x_dnd_atoms_size and x_dnd_atoms_length.
11413
11414 * doprnt.c: Prefer signed to unsigned when either works.
11415 * eval.c (verror):
11416 * doprnt.c (doprnt):
11417 * lisp.h (doprnt):
11418 * xdisp.c (vmessage):
11419 Use ptrdiff_t, not size_t, when using or implementing doprnt,
11420 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
11421 prefer signed arithmetic to avoid comparison confusion.
11422 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
11423 but is a bit tricky.
11424
11425 Assume freestanding C89 headers, string.h, stdlib.h.
11426 * data.c, doprnt.c, floatfns.c, print.c:
11427 Include float.h unconditionally.
11428 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
11429 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
11430 * regex.c: Likewise for stddef.h, string.h.
11431 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
11432 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
11433 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
11434 (STDC_HEADERS): Remove obsolete defines.
11435 * sysdep.c: Include limits.h unconditionally.
11436
11437 Assume support for memcmp, memcpy, memmove, memset.
11438 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
11439 * regex.c (memcmp, memcpy):
11440 Remove; we assume C89 now.
11441
11442 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
11443 (__malloc_safe_bcopy): Remove; no longer needed.
11444
11445 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
11446 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
11447 well either way, and we prefer signed to unsigned.
11448
11449 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
11450
11451 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
11452 closes the connection while we're reading (bug#9182).
11453
11454 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
11455
11456 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
11457 are specified (Bug#9168).
11458
11459 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
11460
11461 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
11462 Found by GCC static checking and --with-wide-int on a 32-bit host.
11463
11464 2011-07-25 Eli Zaretskii <eliz@gnu.org>
11465
11466 * xdisp.c (compute_display_string_pos): Fix logic of caching
11467 previous display string position. Initialize cached_prev_pos to
11468 -1. Fixes slow-down at the beginning of a buffer.
11469
11470 2011-07-24 Eli Zaretskii <eliz@gnu.org>
11471
11472 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
11473 for attrs[LFACE_FONTSET_INDEX].
11474
11475 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
11476
11477 * xml.c (parse_region): Remove unused local
11478 that was recently introduced.
11479
11480 2011-07-23 Eli Zaretskii <eliz@gnu.org>
11481
11482 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
11483 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
11484
11485 * xdisp.c (move_it_in_display_line_to): Record the best matching
11486 position for TO_CHARPOS while scanning the line, and restore it on
11487 exit if none of the characters scanned was an exact match.
11488 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
11489 when exact match is impossible due to invisible text, and the
11490 lines are truncated.
11491
11492 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
11493
11494 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
11495 for OSX >= 10.7.
11496
11497 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11498
11499 Fix a significant slow-down of cursor motion with C-n, C-p,
11500 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
11501 auto-repeat under bidi redisplay in fontified buffers.
11502 * xdisp.c (compute_stop_pos_backwards): New function.
11503 (next_element_from_buffer): Call compute_stop_pos_backwards to
11504 find a suitable prev_stop when we find ourselves before
11505 base_level_stop.
11506 (reseat): Don't look for prev_stop, as that could mean a very long
11507 run.
11508 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
11509 <cached_disp_overlay_modiff>: Cache for last found display string
11510 position.
11511 (compute_display_string_pos): Return the cached position if asked
11512 about the same buffer in the same area of character positions, and
11513 the buffer wasn't changed since the time the display string
11514 position was cached.
11515
11516 2011-07-22 Eli Zaretskii <eliz@gnu.org>
11517
11518 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
11519 is an integer, which is important for empty lines. (Bug#9149)
11520
11521 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
11522
11523 * frame.c (Fmodify_frame_parameters): In tty case, update the
11524 default face if necessary (Bug#4238).
11525
11526 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
11527
11528 * editfns.c (Fstring_to_char): No need to explain what a character
11529 is in the docstring (Bug#6576).
11530
11531 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11532
11533 * xml.c (parse_region): Make sure we always return a tree.
11534
11535 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
11536
11537 * xml.c (parse_region): If a document contains only comments,
11538 return that, too.
11539
11540 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
11541
11542 * xml.c (make_dom): Return comments, too.
11543
11544 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
11545
11546 Port to OpenBSD.
11547 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
11548 and the surrounding thread.
11549 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
11550 rather than fgets, and retry after EINTR. Otherwise, 'emacs
11551 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
11552 timer goes off.
11553 * s/openbsd.h (BROKEN_SIGIO): Define.
11554 * unexelf.c (unexec) [__OpenBSD__]:
11555 Don't update the .mdebug section of the Alpha COFF symbol table.
11556
11557 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11558
11559 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
11560 (bug#8460).
11561
11562 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
11563
11564 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
11565 This fixes some race conditions on the permissions of any newly
11566 created file.
11567
11568 * alloc.c (valid_pointer_p): Use pipe, not open.
11569 This fixes some permissions issues when debugging.
11570
11571 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
11572 If fchown fails to set both uid and gid, try to set just gid,
11573 as that is sometimes allowed. Adjust the file's mode to eliminate
11574 setuid or setgid bits that are inappropriate if fchown fails.
11575
11576 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
11577
11578 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
11579 to compare Lisp_Objects.
11580 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
11581 global_gnutls_log_level, don't mistake it for a Lisp_Object.
11582 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
11583
11584 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
11585
11586 * lread.c (read_integer): Unread even EOF character.
11587 (read1): Likewise. Properly record start position of symbol.
11588
11589 * lread.c (read1): Read `#:' as empty uninterned symbol if no
11590 symbol character follows.
11591
11592 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
11593
11594 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
11595 This works around a problem with the previous change to Fcopy_file.
11596 Recent glibc declares fchown with __attribute__((warn_unused_result)),
11597 and without this change, GCC might complain about discarding
11598 fchown's return value.
11599
11600 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
11601
11602 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
11603
11604 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
11605
11606 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
11607
11608 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
11609
11610 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
11611 it's used from the C level.
11612
11613 * process.c: Use the same condition for POLL_FOR_INPUT in both
11614 keyboard.c and process.c (bug#1858).
11615
11616 2011-07-09 Lawrence Mitchell <wence@gmx.li>
11617
11618 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
11619 (Fgnutls_boot): Use it.
11620
11621 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
11622
11623 * doc.c (Fsubstitute_command_keys): Revert last change.
11624
11625 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
11626
11627 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
11628 quotes the next character, and doesn't affect other longer
11629 sequences (bug#8935).
11630
11631 * lread.c (syms_of_lread): Clarify that is isn't only
11632 `eval-buffer' and `eval-defun' that's affected by
11633 `lexical-binding' (bug#8460).
11634
11635 2011-07-15 Eli Zaretskii <eliz@gnu.org>
11636
11637 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
11638 bidi redisplay when a line includes both an image and is truncated.
11639
11640 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
11641
11642 Fix minor problems found by static checking.
11643 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
11644 (elsz): Now a signed constant, not a size_t var. We prefer signed
11645 types to unsigned, to avoid integer comparison confusion. Without
11646 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
11647 "cannot optimize loop, the loop counter may overflow", a symptom
11648 of the confusion.
11649 * indent.c (Fvertical_motion): Mark locals as initialized.
11650 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
11651
11652 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
11653
11654 * search.c (Fre_search_backward): Mention `case-fold-search' in
11655 all the re_search_* functions (bug#8138).
11656
11657 * keyboard.c (Fopen_dribble_file): Document when the file is
11658 closed (bug#8056).
11659
11660 2011-07-14 Eli Zaretskii <eliz@gnu.org>
11661
11662 * bidi.c (bidi_dump_cached_states): Fix format of displaying
11663 bidi_cache_idx.
11664
11665 Support bidi reordering of display and overlay strings.
11666 * xdisp.c (compute_display_string_pos)
11667 (compute_display_string_end): Accept additional argument STRING.
11668 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
11669 (reseat_to_string): Initialize bidi_it->string.s and
11670 bidi_it->string.schars.
11671 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
11672 NULL (avoids a crash in bidi_paragraph_init).
11673 Initialize itb.string.lstring.
11674 (init_iterator): Call bidi_init_it only of a valid
11675 buffer position was specified. Initialize paragraph_embedding to
11676 L2R.
11677 (reseat_to_string): Initialize the bidi iterator.
11678 (display_string): If we need to ignore text properties of
11679 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
11680 original value of -1 will not work with bidi.)
11681 (compute_display_string_pos): First arg is now struct
11682 `text_pos *'; all callers changed. Support display properties on
11683 Lisp strings.
11684 (compute_display_string_end): Support display properties on Lisp
11685 strings.
11686 (init_iterator, reseat_1, reseat_to_string): Initialize the
11687 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
11688 when iterating on a string not from display properties).
11689 (compute_display_string_pos, compute_display_string_end):
11690 Fix calculation of the object to scan. Fixes an error when using
11691 arrow keys.
11692 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
11693 base_level_stop; instead, set base_level_stop to BEGV.
11694 Fixes crashes in vertical-motion.
11695 (next_element_from_buffer): Improve commentary for when
11696 the iterator is before prev_stop.
11697 (init_iterator): Initialize bidi_p from the default value of
11698 bidi-display-reordering, not from buffer-local value. Use the
11699 buffer-local value only if initializing for buffer iteration.
11700 (handle_invisible_prop): Support invisible properties on strings
11701 that are being bidi-reordered.
11702 (set_iterator_to_next): Support bidi reordering of C strings and
11703 Lisp strings.
11704 (next_element_from_string): Support bidi reordering of Lisp
11705 strings.
11706 (handle_stop_backwards): Support Lisp strings as well.
11707 (display_string): Support display of R2L glyph rows.
11708 Use IT_STRING_CHARPOS when displaying from a Lisp string.
11709 (init_iterator): Don't initialize it->bidi_p for strings
11710 here.
11711 (reseat_to_string): Initialize it->bidi_p for strings here.
11712 (next_element_from_string, next_element_from_c_string)
11713 (next_element_from_buffer): Add xassert's for correspondence
11714 between IT's object being iterated and it->bidi_it.string
11715 structure.
11716 (face_before_or_after_it_pos): Support bidi iteration.
11717 (next_element_from_c_string): Handle the case of the first string
11718 character that is not the first one in the visual order.
11719 (get_visually_first_element): New function, refactored from common
11720 parts of next_element_from_buffer, next_element_from_string, and
11721 next_element_from_c_string.
11722 (tool_bar_lines_needed, redisplay_tool_bar)
11723 (display_menu_bar): Force left-to-right direction. Add a FIXME
11724 comment for making that be controlled by a user option.
11725 (push_it, pop_it): Save and restore the state of the
11726 bidi iterator. Save and restore the bidi_p flag.
11727 (pop_it): Iterate out of display property for string iteration as
11728 well.
11729 (iterate_out_of_display_property): Support iteration over strings.
11730 (handle_single_display_spec): Set up it->bidi_it for iteration
11731 over a display string, and call bidi_init_it.
11732 (handle_single_display_spec, next_overlay_string)
11733 (get_overlay_strings_1, push_display_prop): Set up the bidi
11734 iterator for displaying display or overlay strings.
11735 (forward_to_next_line_start): Don't use the shortcut if
11736 bidi-iterating.
11737 (back_to_previous_visible_line_start): If handle_display_prop
11738 pushed the iterator stack, restore the internal state of the bidi
11739 iterator by calling bidi_pop_it same number of times.
11740 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
11741 and we are bidi-iterating, don't decrement the iterator position;

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

12212
12213 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
12214
12215 Random fixes. E.g., (random) never returned negative values.
12216 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
12217 subseconds part to the entropy, as that's a bit more random.
12218 Prefer signed to unsigned, since the signedness doesn't matter and
12219 in general we prefer signed. When given a limit, use a
12220 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
12221 latter isn't right if USE_2_TAGS_FOR_INTS.
12222 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
12223 not 0..VALMASK. Don't discard "excess" bits that random () returns.
12224
12225 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
12226

12232
12233 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
12234
12235 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
12236 This is more efficient than Ffile_directory_p and avoids a minor race.
12237
12238 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
12239
12240 * buffer.c (Foverlay_put): Say what the return value is
12241 (bug#7835).
12242
12243 * fileio.c (barf_or_query_if_file_exists): Check first if the file
12244 is a directory before asking whether to use the file name
12245 (bug#7564).
12246 (barf_or_query_if_file_exists): Make the "File is a directory"
12247 error be more correct.
12248
12249 * fns.c (Frequire): Remove the mention of the .gz files, since
12250 that's installation-specific, but keep the mention of
12251 `get-load-suffixes'.

12261 (syms_of_gnutls): Remove duplicate DEFSYM for
12262 Qgnutls_bootprop_verify_hostname_error, an error for
12263 Qgnutls_bootprop_verify_error (which is no longer used).
12264
12265 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
12266 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
12267 Also (re)move comments that are misplaced or no longer relevant.

12284 * xsettings.c (SYSTEM_FONT): Define only when used.
12285 No need to define when HAVE_GSETTINGS || !HAVE_XFT.
12286
12287 * keymap.c (access_keymap_1): Now static.
12288
12289 2011-07-02 Chong Yidong <cyd@stupidchicken.com>
12290

12352 (something_changedCB): HAVE_GCONF: Call store_monospaced_changed
12353 with value as argument.
12354 (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
12355 g_settings_new (Bug#8967). Do not create gsettings_obj.

12367
12368 * eval.c (struct backtrace): Simplify and port the data structure.
12369 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
12370 signed bit field, as this assumption is not portable and it makes
12371 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
12372 "char debug_on_exit : 1" as this is not portable either; instead,
12373 use the portable "unsigned int debug_on_exit : 1". Remove unused
12374 member evalargs. Remove obsolete comments about cc bombing out.
12375
12376 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

12412 and not through other includes.
12413
12414 2011-06-27 Martin Rudalics <rudalics@gmx.at>
12415
12416 * buffer.c (Qclone_number): Declare static and DEFSYM it.
12417 (sort_overlays, overlay_strings): When an overlay's clone number
12418 matches the window's clone number process the overlay even if

12457
12458 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling

12469

12541
12542 * print.c (printchar, strout): Check for string overflow.
12543 (PRINTPREPARE, printchar, strout):
12544 Don't set size unless allocation succeeds.
12545
12546 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
12547 for sizes. Check for string overflow more accurately.
12548 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
12549
12550 * macros.c: Integer and buffer overflow fixes.
12551 * keyboard.h (struct keyboard.kbd_macro_bufsize):
12552 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
12553 Use ptrdiff_t, not int, for sizes.
12554 Don't increment bufsize until after realloc succeeds.
12555 Check for size-calculation overflow.
12556 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
12557
12558 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
12559
12560 * lread.c: Integer overflow fixes.
12561 (read_integer): Radix is now EMACS_INT, not int,
12562 to improve quality of diagnostics for out-of-range radices.
12563 Calculate buffer size correctly for out-of-range radices.
12564 (read1): Check for integer overflow in radices, and in
12565 read-circle numbers.
12566 (read_escape): Avoid int overflow.
12567 (Fload, openp, read_buffer_size, read1)
12568 (substitute_object_recurse, read_vector, read_list, map_obarray):
12569 Use ptrdiff_t, not int, for sizes.
12570 (read1): Use EMACS_INT, not int, for sizes.
12571 Check for size overflow.
12572
12573 * image.c (cache_image): Check for size arithmetic overflow.
12574
12575 * lread.c: Integer overflow issues.
12576 (saved_doc_string_size, saved_doc_string_length)
12577 (prev_saved_doc_string_size, prev_saved_doc_string_length):
12578 Now ptrdiff_t, not int.
12579 (read1): Don't assume doc string length fits in int. Check for
12580 out-of-range doc string lengths.
12581 (read_list): Don't assume file position fits in int.
12582 (read_escape): Check for hex character overflow.
12583
12584 2011-06-22 Leo Liu <sdl.web@gmail.com>
12585
12586 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
12587 Move to minibuffer.el.
12588
12589 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12590
12591 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
12592 The following patches are for when GLYPH_DEBUG && !XASSERT.
12593 * dispextern.h (trace_redisplay_p, dump_glyph_string):
12594 * dispnew.c (flush_stdout):
12595 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
12596 Mark as externally visible.
12597 * dispnew.c (check_window_matrix_pointers): Now static.
12598 * dispnew.c (window_to_frame_vpos):
12599 * xfns.c (unwind_create_frame):
12600 * xterm.c (x_check_font): Remove unused local.
12601 * scroll.c (CHECK_BOUNDS):
12602 * xfaces.c (cache_fache): Rename local to avoid shadowing.
12603 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
12604 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
12605 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
12606 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
12607 Now static.
12608 (debug_method_add): Use va_list and vsprintf rather than relying
12609 on undefined behavior with wrong number of arguments.
12610 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
12611 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
12612 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
12613 since we're not interested in debugging glyphs with old libraries.
12614 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
12615 GCC 4.6.0's static checking.
12616
12617 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
12618
12619 Integer overflow and signedness fixes (Bug#8873).

12634 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
12635 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
12636 (.bitmaps_last, struct x_output.icon_bitmap):
12637 Use ptrdiff_t, not int, for bitmap indexes.
12638 (x_allocate_bitmap_record): Check for size overflow.
12639 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
12640
12641 Use ptrdiff_t, not int, for overlay counts.
12642 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
12643 * editfns.c (overlays_around, get_pos_property):
12644 * textprop.c (get_char_property_and_overlay):
12645 * xdisp.c (next_overlay_change, note_mouse_highlight):
12646 * xfaces.c (face_at_buffer_position):
12647 * buffer.c (OVERLAY_COUNT_MAX): New macro.
12648 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
12649 (Fnext_overlay_change, Fprevious_overlay_change)
12650 (mouse_face_overlay_overlaps, Foverlays_in):
12651 Use ptrdiff_t, not int, for sizes.
12652 (overlays_at, overlays_in): Check for size-calculation overflow.
12653
12654 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
12655
12656 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
12657 (x_session_initialize): Do not assume string length fits in int.
12658
12659 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
12660 This is unlikely, but can occur if DPI is outlandish.
12661
12662 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
12663 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
12664
12665 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
12666 * xrdb.c (magic_file_p, search_magic_path):
12667 Omit last arg SUFFIX; it was always 0. All callers changed.
12668 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
12669
12670 * xfont.c (xfont_match): Avoid need for strlen.
12671
12672 * xfns.c: Don't assume strlen fits in int.
12673 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
12674
12675 * xdisp.c (message_log_check_duplicate): Return intmax_t,
12676 not unsigned long, as we prefer signed integers. All callers changed.
12677 Detect integer overflow in repeat count.
12678 (message_dolog): Don't assume print length fits in 39 bytes.
12679 (display_mode_element): Don't assume strlen fits in int.
12680
12681 * termcap.c: Don't assume sizes fit in int and never overflow.
12682 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
12683 (gobble_line): Check for size-calculation overflow.
12684
12685 * minibuf.c (Fread_buffer):
12686 * lread.c (intern, intern_c_string):
12687 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
12688 Don't assume string length fits in int.
12689
12690 * keyboard.c (parse_tool_bar_item):
12691 * gtkutil.c (style_changed_cb): Avoid need for strlen.
12692

12698 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
12699
12700 * filelock.c: Fix some buffer overrun and integer overflow issues.
12701 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
12702 Reformulate so as not to need the command string.
12703 Invoke gzip -cd rather than gunzip, as it's more portable.
12704 (lock_info_type, lock_file_1, lock_file):
12705 Don't assume pid_t and time_t fit in unsigned long.
12706 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
12707 (current_lock_owner): Prefer signed type for sizes.
12708 Use memcpy, not strncpy, where memcpy is what is really wanted.
12709 Don't assume (via atoi) that time_t and pid_t fit in int.
12710 Check for time_t and/or pid_t out of range, e.g., via a network share.
12711 Don't alloca where an auto var works fine.
12712
12713 * fileio.c: Fix some integer overflow issues.
12714 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
12715 Don't assume string length fits in int.
12716 (directory_file_name): Don't assume string length fits in long.
12717 (make_temp_name): Don't assume pid fits in int, or that its print
12718 length is less than 20.
12719
12720 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
12721
12722 * coding.c (make_subsidiaries): Don't assume string length fits in int.
12723
12724 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
12725
12726 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
12727 We prefer signed integers, even for size calculations.
12728
12729 * emacs.c: Don't assume string length fits in 'int'.
12730 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
12731 (main): Don't invoke strlen when not needed.
12732
12733 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
12734 (XD_DEBUG_MESSAGE): Don't waste a byte.
12735
12736 * callproc.c (getenv_internal_1, getenv_internal)
12737 (Fgetenv_internal):
12738 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
12739
12740 * lread.c (invalid_syntax): Omit length argument.
12741 All uses changed. This doesn't fix a bug, but it simplifies the
12742 code away from its former Hollerith-constant appearance, and it's
12743 one less 'int' to worry about when looking at integer-overflow issues.
12744 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
12745
12746 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
12747 This didn't break anything, but it didn't help either.
12748 It's confusing to put a bogus integer in a place where the actual
12749 value does not matter.
12750 (LIST_END_P): Remove unused macro and its bogus comment.
12751 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
12752
12753 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
12754 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
12755 implementation.
12756 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
12757 We prefer signed types, and the value cannot exceed the EMACS_INT
12758 range anyway (because otherwise the length would not be representable).
12759 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
12760 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
12761 This avoids a GCC warning when WIDE_EMACS_INT.
12762
12763 * indent.c (sane_tab_width): New function.
12764 (current_column, scan_for_column, Findent_to, position_indentation)
12765 (compute_motion): Use it. This is just for clarity.
12766 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
12767
12768 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
12769
12770 * lisp.h (lint_assume): New macro.
12771 * composite.c (composition_gstring_put_cache):
12772 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
12773
12774 * editfns.c, insdel.c:
12775 Omit unnecessary forward decls, to simplify future changes.
12776
12777 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
12778
12779 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
12780
12781 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
12782 Use much-faster test for byte-length change.
12783 Don't assume string byte-length fits in 'int'.
12784 Check that character arg fits in 'int'.
12785 (mapcar1): Declare byte as byte, for clarity.
12786
12787 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
12788
12789 * fns.c (concat): Catch string overflow earlier.
12790 Do not rely on integer wraparound.
12791
12792 * dispextern.h (struct it.overlay_strings_charpos)
12793 (struct it.selective): Now EMACS_INT, not int.
12794 * xdisp.c (forward_to_next_line_start)
12795 (back_to_previous_visible_line_start)
12796 (reseat_at_next_visible_line_start, next_element_from_buffer):
12797 Don't arbitrarily truncate the value of 'selective' to int.
12798
12799 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
12800
12801 * composite.c: Don't truncate sizes to 'int'.
12802 (composition_gstring_p, composition_reseat_it)
12803 (composition_adjust_point): Use EMACS_INT, not int.
12804 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
12805 not EMACS_UINT, for indexes.
12806
12807 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
12808
12809 * buffer.c: Include <verify.h>.
12810 (struct sortvec.priority, struct sortstr.priority):
12811 Now EMACS_INT, not int.
12812 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
12813 (struct sortstr.size, record_overlay_string)
12814 (struct sortstrlist.size, struct sortlist.used):
12815 Don't truncate size to int.
12816 (record_overlay_string): Check for size-calculation overflow.
12817 (init_buffer_once): Check at compile-time, not run-time.
12818
12819 2011-06-22 Jim Meyering <meyering@redhat.com>
12820
12821 Don't leak an XBM-image-sized buffer
12822 * image.c (xbm_load): Free the image buffer after using it.
12823
12824 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
12825
12826 Port to Sun C.
12827 * composite.c (find_automatic_composition): Omit needless 'return 0;'
12828 that Sun C diagnosed.
12829 * fns.c (secure_hash): Fix pointer signedness issue.
12830 * intervals.c (static_offset_intervals): New function.
12831 (offset_intervals): Use it.
12832
12833 2011-06-21 Leo Liu <sdl.web@gmail.com>
12834
12835 * deps.mk (fns.o):
12836 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
12837 sha512.h.
12838
12839 * fns.c (secure_hash): Rename from crypto_hash_function and change
12840 the first arg to accept symbols.
12841 (Fsecure_hash): New primitive.
12842 (syms_of_fns): New symbols.
12843
12844 2011-06-20 Deniz Dogan <deniz@dogan.se>
12845
12846 * process.c (Fset_process_buffer): Clarify return value in
12847 docstring.
12848
12849 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
12850
12851 * dispnew.c (add_window_display_history): Use BVAR.
12852
12853 * xdisp.c (debug_method_add): Use BVAR.
12854 (check_window_end, dump_glyph_matrix, dump_glyph)
12855 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
12856
12857 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
12858 Likewise.
12859
12860 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
12861 check till after the cache is created in init_frame_faces.
12862
12863 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
12864
12865 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
12866
12867 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
12868
12869 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
12870 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
12871 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
12872
12873 Improve buffer-overflow checking (Bug#8873).
12874 * fileio.c (Finsert_file_contents):
12875 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
12876 Remove the old (too-loose) buffer overflow checks.
12877 They weren't needed, since make_gap checks for buffer overflow.
12878 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
12879 The old code merely checked for Emacs fixnum overflow, and relied
12880 on undefined (wraparound) behavior. The new code avoids undefined
12881 behavior, and also checks for ptrdiff_t and/or size_t overflow.
12882
12883 * editfns.c (Finsert_char): Don't dump core with very negative counts.
12884 Tune. Don't use wider integers than needed. Don't use alloca.
12885 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
12886
12887 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
12888
12889 * insdel.c, lisp.h (buffer_overflow): New function.
12890 (insert_from_buffer_1, replace_range, replace_range_2):
12891 * insdel.c (make_gap_larger):
12892 * editfns.c (Finsert_char):
12893 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
12894
12895 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
12896
12897 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
12898
12899 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
12900
12901 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
12902 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
12903
12904 * fileio.c: Don't assume EMACS_INT fits in off_t.
12905 (emacs_lseek): New static function.
12906 (Finsert_file_contents, Fwrite_region): Use it.
12907 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
12908
12909 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
12910
12911 * fns.c: Don't overflow int when computing a list length.
12912 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
12913 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
12914 truncation on 64-bit hosts. Check for QUIT every
12915 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
12916 faster and is responsive enough.
12917 (Flength): Report an error instead of overflowing an integer.
12918 (Fsafe_length): Return a float if the value is not representable
12919 as a fixnum. This shouldn't happen except in contrived situations.
12920 (Fnthcdr, Fsort): Don't assume list length fits in int.
12921 (Fcopy_sequence): Don't assume vector length fits in int.
12922
12923 * alloc.c: Check that resized vectors' lengths fit in fixnums.
12924 (header_size, word_size): New constants.
12925 (allocate_vectorlike): Don't check size overflow here.
12926 (allocate_vector): Check it here instead, since this is the only
12927 caller of allocate_vectorlike that could cause overflow.
12928 Check that the new vector's length is representable as a fixnum.
12929
12930 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
12931 The previous code was bogus. For example, next_almost_prime (32)
12932 returned 39, which is undesirable as it is a multiple of 3; and
12933 next_almost_prime (24) returned 25, which is a multiple of 5 so
12934 why was the code bothering to check for multiples of 7?
12935
12936 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
12937
12938 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
12939
12940 Variadic C functions now count arguments with ptrdiff_t.
12941 This partly undoes my 2011-03-30 change, which replaced int with size_t.
12942 Back then I didn't know that the Emacs coding style prefers signed int.
12943 Also, in the meantime I found a few more instances where arguments
12944 were being counted with int, which may truncate counts on 64-bit
12945 machines, or EMACS_INT, which may be unnecessarily wide.
12946 * lisp.h (struct Lisp_Subr.function.aMANY)
12947 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
12948 Arg counts are now ptrdiff_t, not size_t.
12949 All variadic functions and their callers changed accordingly.
12950 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
12951 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
12952 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
12953 * callint.c (Fcall_interactively): Check arg count for overflow,
12954 to avoid potential buffer overrun. Use signed char, not 'int',
12955 for 'varies' array, so that we needn't bother to check its size
12956 calculation for overflow.
12957 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
12958 * eval.c (apply_lambda):
12959 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
12960 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
12961 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
12962
12963 * callint.c (Fcall_interactively): Don't use index var as event count.
12964
12965 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
12966 * mem-limits.h (SIZE): Remove; no longer used.
12967
12968 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
12969
12970 Remove unnecessary casts.
12971 * xterm.c (x_term_init):
12972 * xfns.c (x_set_border_pixel):
12973 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
12974 These aren't needed now that we assume ANSI C.
12975
12976 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
12977 It's more likely to cause problems (due to unsigned overflow)
12978 than to cure them.
12979
12980 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
12981
12982 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
12983
12984 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
12985
12986 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
12987
12988 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
12989
12990 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
12991
12992 GLYPH_CODE_FACE returns EMACS_INT, not int.
12993 * dispextern.h (merge_faces):
12994 * xfaces.c (merge_faces):
12995 * xdisp.c (get_next_display_element, next_element_from_display_vector):
12996 Don't assume EMACS_INT fits in int.
12997
12998 * character.h (CHAR_VALID_P): Remove unused parameter.
12999 * fontset.c, lisp.h, xdisp.c: All uses changed.
13000
13001 * editfns.c (Ftranslate_region_internal): Omit redundant test.
13002
13003 * fns.c (concat): Minor tuning based on overflow analysis.
13004 This doesn't fix any bugs. Use int to hold character, instead
13005 of constantly refetching from Emacs object. Use XFASTINT, not
13006 XINT, for value known to be a character. Don't bother comparing
13007 a single byte to 0400, as it's always less.
13008
13009 * floatfns.c (Fexpt):
13010 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
13011
13012 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
13013 for characters.
13014
13015 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
13016
13017 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
13018 Without this fix, on a 64-bit host (aset S 0 4294967386) would
13019 incorrectly succeed when S was a string, because 4294967386 was
13020 truncated before it was used.
13021
13022 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
13023 Otherwise, an out-of-range integer could cause undefined behavior
13024 on a 64-bit host.
13025
13026 * composite.c: Use int, not EMACS_INT, for characters.
13027 (fill_gstring_body, composition_compute_stop_pos): Use int, not
13028 EMACS_INT, for values that are known to be in character range.
13029 This doesn't fix any bugs but is the usual style inside Emacs and
13030 may generate better code on 32-bit machines.
13031
13032 Make sure a 64-bit char is never passed to ENCODE_CHAR.
13033 This is for reasons similar to the recent CHAR_STRING fix.
13034 * charset.c (Fencode_char): Check that character arg is actually
13035 a character. Pass an int to ENCODE_CHAR.
13036 * charset.h (ENCODE_CHAR): Verify that the character argument is no
13037 wider than 'int', as a compile-time check to prevent future regressions
13038 in this area.
13039
13040 * character.c (char_string): Remove unnecessary casts.
13041
13042 Make sure a 64-bit char is never passed to CHAR_STRING.
13043 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
13044 by silently ignoring the top 32 bits, allowing some values
13045 that were far too large to be valid characters.
13046 * character.h: Include <verify.h>.
13047 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
13048 arguments are no wider than unsigned, as a compile-time check
13049 to prevent future regressions in this area.
13050 * data.c (Faset):
13051 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
13052 (Fsubst_char_in_region):
13053 * fns.c (concat):
13054 * xdisp.c (decode_mode_spec_coding):
13055 Adjust to CHAR_STRING's new requirement.
13056 * editfns.c (Finsert_char, Fsubst_char_in_region):
13057 * fns.c (concat): Check that character args are actually
13058 characters. Without this test, these functions did the wrong
13059 thing with wildly out-of-range values on 64-bit hosts.
13060
13061 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
13062 These casts should not be needed on 32-bit hosts, either.
13063 * keyboard.c (read_char):
13064 * lread.c (Fload): Remove casts to unsigned.
13065
13066 * lisp.h (UNSIGNED_CMP): New macro.
13067 This fixes comparison bugs on 64-bit hosts.
13068 (ASCII_CHAR_P): Use it.
13069 * casefiddle.c (casify_object):
13070 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
13071 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
13072 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
13073 * dispextern.h (FACE_FROM_ID):
13074 * keyboard.c (read_char): Use UNSIGNED_CMP.
13075
13076 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
13077 not to EMACS_INT, to avoid GCC warning.
13078
13079 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
13080
13081 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
13082 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
13083 isn't needed on 32-bit machines.
13084
13085 * buffer.c (Fgenerate_new_buffer_name):
13086 Use EMACS_INT for count, not int.
13087 (advance_to_char_boundary): Return EMACS_INT, not int.
13088
13089 * data.c (Qcompiled_function): Now static.
13090
13091 * window.c (window_body_lines): Now static.
13092
13093 * image.c (gif_load): Rename local to avoid shadowing.
13094
13095 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
13096 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
13097 * alloc.c (make_save_value): Integer argument is now of type
13098 ptrdiff_t, not int.
13099 (mark_object): Use ptrdiff_t, not int.
13100 * lisp.h (pD): New macro.
13101 * print.c (print_object): Use it.
13102
13103 * alloc.c: Use EMACS_INT, not int, to count objects.
13104 (total_conses, total_markers, total_symbols, total_vector_size)
13105 (total_free_conses, total_free_markers, total_free_symbols)
13106 (total_free_floats, total_floats, total_free_intervals)
13107 (total_intervals, total_strings, total_free_strings):
13108 Now EMACS_INT, not int. All uses changed.
13109 (Fgarbage_collect): Compute overall total using a double, so that
13110 integer overflow is less likely to be a problem. Check for overflow
13111 when converting back to an integer.
13112 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
13113 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
13114 These were 'int' variables that could overflow on 64-bit hosts;
13115 they were never used, so remove them instead of repairing them.
13116 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
13117 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
13118 Previously, this ceilinged at INT_MAX, but that doesn't work on
13119 64-bit machines.
13120 (allocate_pseudovector): Don't use EMACS_INT when int would do.
13121
13122 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
13123 (allocate_vectorlike): Check for ptrdiff_t overflow.
13124 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
13125 when a (possibly-narrower) signed value would do just as well.
13126 We prefer using signed arithmetic, to avoid comparison confusion.
13127
13128 * alloc.c: Catch some string size overflows that we were missing.
13129 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
13130 for convenience in STRING_BYTES_MAX.
13131 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
13132 The definition here is exact; the one in lisp.h was approximate.
13133 (allocate_string_data): Check for string overflow. This catches
13134 some instances we weren't catching before. Also, it catches
13135 size_t overflow on (unusual) hosts where SIZE_MAX <= min
13136 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
13137 and ptrdiff_t and EMACS_INT are both 64 bits.
13138
13139 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
13140 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
13141 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
13142
13143 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
13144
13145 * alloc.c (Fmake_string): Check for out-of-range init.
13146
13147 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
13148
13149 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
13150
13151 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
13152
13153 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
13154 xg_get_default_scrollbar_width.
13155
13156 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
13157 (int_gtk_range_get_value): Move to the scroll bar part of the file.
13158 (style_changed_cb): Call update_theme_scrollbar_width and call
13159 x_set_scroll_bar_default_width and xg_frame_set_char_size for
13160 all frames (Bug#8505).
13161 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
13162 Call gtk_window_set_resizable if HAVE_GTK3.
13163 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
13164 and height if HAVE_GTK3 (Bug#8505).
13165 (scroll_bar_width_for_theme): New variable.
13166 (update_theme_scrollbar_width): New function.
13167 (xg_get_default_scrollbar_width): Move code to
13168 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
13169 (xg_initialize): Call update_theme_scrollbar_width.
13170
13171 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
13172
13173 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
13174
13175 2011-06-12 Martin Rudalics <rudalics@gmx.at>
13176
13177 * frame.c (make_frame): Call other_buffer_safely instead of
13178 other_buffer.
13179
13180 * window.c (temp_output_buffer_show): Call display_buffer with
13181 second argument Vtemp_buffer_show_specifiers and reset latter
13182 immediately after the call.
13183 (Vtemp_buffer_show_specifiers): New variable.
13184 (auto_window_vscroll_p, next_screen_context_lines)
13185 (Vscroll_preserve_screen_position): Remove leading asterisks from
13186 doc-strings.
13187
13188 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
13189
13190 Fix minor problems found by GCC 4.6.0 static checking.

13192 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
13193 (record_buffer): Remove unused local.
13194 * frame.c (other_visible_frames, frame_buffer_list): Now static.
13195 (set_frame_buffer_list): Remove; unused.
13196 * frame.h (other_visible_frames): Remove decl.
13197 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
13198 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
13199 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
13200 if HAVE_GPM.
13201 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
13202 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
13203 Define only if HAVE_GPM.
13204 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
13205 (update_hints_inhibit): Remove; never set. All uses removed.
13206 * widgetprv.h (emacsFrameClassRec): Remove decl.
13207 * window.c (delete_deletable_window): Now returns void, since it
13208 wasn't returning anything.
13209 (compare_window_configurations): Remove unused locals.
13210 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
13211 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
13212 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
13213 the same widths as pointers. This follows up on the 2011-05-06 patch.
13214 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
13215 * xterm.h: Likewise.
13216 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
13217

13223 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
13224
13225 * image.c (gif_load): Add animation frame delay to the metadata.
13226 (syms_of_image): Use DEFSYM. New symbol `delay'.
13227
13228 2011-06-11 Martin Rudalics <rudalics@gmx.at>
13229
13230 * window.c (delete_deletable_window): Re-add.
13231 (Fset_window_configuration): Rewrite to handle dead buffers and
13232 consequently deletable windows.
13233 (window_tree, Fwindow_tree): Remove. Supply functionality in
13234 window.el.
13235 (compare_window_configurations): Simplify code.
13236
13237 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
13238
13239 * image.c (imagemagick_load_image): Fix type mismatch.
13240 (Fimagemagick_types): Likewise.
13241
13242 * window.h (replace_buffer_in_windows): Declare.
13243
13244 2011-06-11 Martin Rudalics <rudalics@gmx.at>
13245
13246 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
13247 Qclone_number. Remove external declaration of Qdelete_window.
13248 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
13249 code.
13250 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
13251 Run Qbuffer_list_update_hook if allowed.
13252 (Fother_buffer): Rewrite doc-string. Major rewrite for new
13253 buffer list implementation.
13254 (other_buffer_safely): New function.
13255 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
13256 calls to replace_buffer_in_windows and
13257 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
13258 if allowed.
13259 (record_buffer): Inhibit quitting and rewrite using quittable
13260 functions. Run Qbuffer_list_update_hook if allowed.
13261 (Frecord_buffer, Funrecord_buffer): New functions.
13262 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
13263 Move switch-to-buffer to window.el.
13264 (bury-buffer): Move to window.el.
13265 (Vbuffer_list_update_hook): New variable.
13266
13267 * lisp.h (other_buffer_safely): Add prototype in buffer.c
13268 section.
13269

13277 (Fnext_window, Fprevious_window): Rewrite doc-strings.
13278 (Fother_window): Move to window.el.
13279 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER

13286 moved into replace_buffer_in_windows_safely.
13287 (replace_buffer_in_windows_safely): New function.
13288 (select_window_norecord, select_frame_norecord): Move in front
13289 of run_window_configuration_change_hook. Remove now obsolete
13290 declarations.
13291 (Fset_window_buffer): Rewrite doc-string.
13292 Call Qrecord_window_buffer.

13296
13297 * dispextern.h (struct image): Replace data member, whose int_val
13298 and ptr_val fields were not used by anything, with a single
13299 lisp_val object.

13302 (gif_clear_image, gif_load, imagemagick_load_image)
13303 (gs_clear_image, gs_load): Callers changed.
13304
13305 2011-06-10 Paul Eggert <eggert@cs.ucla.edu>
13306
13307 * buffer.h: Include <time.h>, for time_t.
13308 Needed to build on FreeBSD 8.2. Problem reported by Herbert J. Skuhra.

13711 (bidi_level_of_next_char): Call bidi_fetch_char and
13712 bidi_fetch_char_advance instead of FETCH_CHAR and
13713 FETCH_CHAR_ADVANCE.
13714 (bidi_init_it): Initialize new members.
13715 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
13716 definitions.
13717 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
13718 instead of using explicit *_CHAR codes.
13719 (bidi_resolve_explicit, bidi_resolve_weak):
13720 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
13721 bidirectional text is supported only in multibyte buffers.
13722 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
13723 it to initialize the frame_window_p member of struct bidi_it.
13724 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
13725 (bidi_resolve_explicit, bidi_resolve_weak)
13726 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
13727 bidi_it->nchars is non-positive.
13728 (bidi_level_of_next_char): Don't try to lookup the cache for the
13729 next/previous character if nothing is cached there yet, or if we
13730 were just reseat()'ed to a new position.
13731
13732 * xdisp.c (set_cursor_from_row): Set start and stop points
13733 according to the row's direction when priming the loop that looks
13734 for the glyph on which to display cursor.
13735 (single_display_spec_intangible_p): Function deleted.
13736 (display_prop_intangible_p): Reimplement to call
13737 handle_display_spec instead of single_display_spec_intangible_p.
13738 Accept 3 additional arguments needed by handle_display_spec.
13739 This fixes incorrect cursor motion across display property with complex
13740 values: lists, `(when COND...)' forms, etc.
13741 (single_display_spec_string_p): Support property values that are
13742 lists with the argument STRING its top-level element.
13743 (display_prop_string_p): Fix the condition for processing a
13744 property that is a list to be consistent with handle_display_spec.
13745 (handle_display_spec): New function, refactored from the
13746 last portion of handle_display_prop.
13747 (compute_display_string_pos): Accept additional argument
13748 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
13749 value of a `display' property is a "replacing spec".
13750 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
13751 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
13752 the display property, but just return a value indicating whether
13753 the display property will replace the characters it covers.
13754 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
13755 frame_window_p members of struct bidi_it.
13756 (compute_display_string_pos, compute_display_string_end):
13757 New functions.
13758 (push_it): Accept second argument POSITION, where pop_it should
13759 jump to continue iteration.
13760 (reseat_1): Initialize bidi_it.disp_pos.
13761
13762 * keyboard.c (adjust_point_for_property): Adjust the call to
13763 display_prop_intangible_p to its new signature.
13764
13765 * dispextern.h (struct bidi_it): New member frame_window_p.
13766 (bidi_init_it): Update prototypes.
13767 (display_prop_intangible_p): Update prototype.
13768 (compute_display_string_pos, compute_display_string_end):
13769 Declare prototypes.
13770 (struct bidi_it): New members nchars and disp_pos. ch_len is now
13771 EMACS_INT.
13772
13773 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
13774
13775 Malloc failure behavior now depends on size of allocation.
13776 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
13777 * lisp.h: Change signatures accordingly.
13778 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
13779 All callers changed. (Bug#8762)
13780
13781 * gnutls.c: Use Emacs's memory allocators.
13782 Without this change, the gnutls library would invoke malloc etc.
13783 directly, which causes problems on non-SYNC_INPUT hosts, and which
13784 runs afoul of improving memory_full behavior. (Bug#8761)
13785 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
13786 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
13787 xfree instead of the default malloc, realloc, free.
13788 (Fgnutls_boot): No need to check for memory allocation failure,
13789 since xmalloc does that for us.
13790
13791 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
13792 * category.c (hash_get_category_set):
13793 * ccl.c (ccl_driver):
13794 * charset.c (Fdefine_charset_internal):
13795 * charset.h (struct charset.hash_index):
13796 * composite.c (get_composition_id, gstring_lookup_cache)
13797 (composition_gstring_put_cache):
13798 * composite.h (struct composition.hash_index):
13799 * dispextern.h (struct image.hash):
13800 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
13801 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
13802 (hashfn_equal, hashfn_user_defined, make_hash_table)
13803 (maybe_resize_hash_table, hash_lookup, hash_put)
13804 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
13805 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
13806 (Fsxhash, Fgethash, Fputhash, Fmaphash):
13807 * image.c (make_image, search_image_cache, lookup_image)
13808 (xpm_put_color_table_h):
13809 * lisp.h (struct Lisp_Hash_Table):
13810 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
13811 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
13812 for hashes and hash indexes, instead of 'unsigned' and 'int'.
13813 * alloc.c (allocate_vectorlike):
13814 Check for overflow in vector size calculations.
13815 * ccl.c (ccl_driver):
13816 Check for overflow when converting EMACS_INT to int.
13817 * fns.c, image.c: Remove unnecessary static decls that would otherwise
13818 need to be updated by these changes.
13819 * fns.c (make_hash_table, maybe_resize_hash_table):
13820 Check for integer overflow with large hash tables.
13821 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
13822 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
13823 (SXHASH_REDUCE): New macro.
13824 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
13825 Use it instead of discarding useful hash info with large hash values.
13826 (sxhash_float): New function.
13827 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
13828 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
13829 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
13830 Rewrite to use FIXNUM_BITS, as this simplifies things.
13831 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
13832 Adjust signatures to match updated version of code.
13833 (consing_since_gc): Now EMACS_INT, since a single hash table can
13834 use more than INT_MAX bytes.
13835
13836 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
13837
13838 Make it possible to build with GCC-4.6+ -O2 -flto.
13839
13840 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
13841
13842 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
13843
13844 * minibuf.c (get_minibuffer, read_minibuf_unwind):
13845 Call minibuffer-inactive-mode.
13846
13847 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
13848
13849 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
13850 Update dependencies.
13851
13852 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
13853
13854 * data.c (init_data): Remove code for UTS, this system is not
13855 supported anymore.
13856
13857 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
13858
13859 Don't force ./temacs to start in terminal mode.
13860
13861 * frame.c (make_initial_frame): Initialize faces in all cases, not
13862 only when CANNOT_DUMP is defined.
13863 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
13864
13865 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
13866
13867 * dispnew.c (add_window_display_history): Use const for the string
13868 pointer. Remove declaration, not needed.
13869
13870 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
13871
13872 Use 'inline', not 'INLINE'.
13873 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
13874 * alloc.c, fontset.c (INLINE): Remove.
13875 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
13876 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
13877 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
13878 * gmalloc.c (register_heapinfo): Use inline unconditionally.
13879 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
13880
13881 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
13882
13883 Make it possible to run ./temacs.
13884
13885 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
13886 syms_of_callproc does the same thing. Remove test for
13887 "initialized", do it in the caller.
13888 * emacs.c (main): Avoid calling set_initial_environment when dumping.
13889
13890 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
13891
13892 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
13893 (read_minibuf): Use get_minibuffer.
13894 (syms_of_minibuf): Use DEFSYM.
13895 (Qmetadata): New var.
13896 * data.c (Qbuffer): Don't make it static.
13897 (syms_of_data): Use DEFSYM.
13898
13899 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
13900
13901 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
13902 (CCL_CODE_MIN): New macro.
13903
13904 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
13905
13906 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
13907
13908 * eval.c (Qdebug): Now static.
13909 * lisp.h (Qdebug): Remove decl. This reverts a part of the
13910 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
13911 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
13912
13913 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13914
13915 * image.c: Various fixes to ImageMagick code comments.
13916 (Fimagemagick_types): Doc fix.
13917
13918 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
13919
13920 Minor fixes prompted by GCC 4.6.0 warnings.
13921
13922 * xselect.c (converted_selections, conversion_fail_tag): Now static.
13923
13924 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
13925 (x_clipboard_manager_save_all): Move extern decl to ...
13926 * xterm.h: ... here, so that it can be checked for consistency.
13927
13928 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
13929
13930 * xselect.c (x_clipboard_manager_save_frame)
13931 (x_clipboard_manager_save_all): New functions.
13932 (Fx_clipboard_manager_save): Lisp function deleted.
13933
13934 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
13935 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
13936
13937 * xterm.h: Update prototype.
13938
13939 2011-05-28 William Xu <william.xwl@gmail.com>
13940
13941 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
13942 exiting (Bug#8239).
13943
13944 2011-05-28 Jim Meyering <meyering@redhat.com>
13945
13946 Avoid a sign-extension bug in crypto_hash_function.
13947 * fns.c (to_uchar): Define.
13948 (crypto_hash_function): Use it to convert some newly-signed
13949 variables to unsigned, to avoid sign-extension bugs. For example,
13950 without this change, (md5 "truc") would evaluate to
13951 45723a2aff78ff4fff7fff1114760e62 rather than the expected
13952 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
13953 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
13954
13955 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
13956
13957 Integer overflow fixes.
13958
13959 * dbusbind.c: Serial number integer overflow fixes.
13960 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
13961 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
13962 to hold a serial number that is too large for a fixnum.
13963 (Fdbus_method_return_internal, Fdbus_method_error_internal):
13964 Check for serial numbers out of range. Decode any serial number
13965 that was so large that it became a float. (Bug#8722)
13966
13967 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
13968 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13969 Use XFASTINT rather than XUINT when numbers are nonnegative.
13970 (xd_append_arg, Fdbus_method_return_internal):
13971 (Fdbus_method_error_internal): Likewise. Also, for unsigned
13972 arguments, check that Lisp number is nonnegative, rather than
13973 silently wrapping negative numbers around. (Bug#8722)
13974 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
13975 (Bug#8722)
13976
13977 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
13978
13979 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
13980
13981 ccl: Add integer overflow checks.
13982 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
13983 (IN_INT_RANGE): New macros.
13984 (ccl_driver): Use them to check for integer overflow when
13985 decoding a CCL program. Many of the new checks are whether XINT (x)
13986 fits in int; it doesn't always, on 64-bit hosts. The new version
13987 doesn't catch all possible integer overflows, but it's an
13988 improvement. (Bug#8719)
13989
13990 * alloc.c (make_event_array): Use XINT, not XUINT.
13991 There's no need for unsigned here.
13992
13993 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
13994 This follows up to the 2011-05-06 change that substituted uintptr_t
13995 for EMACS_INT. This case wasn't caught back then.
13996
13997 Rework Fformat to avoid integer overflow issues.
13998 * editfns.c: Include <float.h> unconditionally, as it's everywhere
13999 now (part of C89). Include <verify.h>.
14000 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
14001 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
14002 (Fformat): Avoid the prepass trying to compute sizes; it was only
14003 approximate and thus did not catch overflow reliably. Instead, walk
14004 through the format just once, formatting and computing sizes as we go,
14005 checking for integer overflow at every step, and allocating a larger
14006 buffer as needed. Keep track separately whether the format is
14007 multibyte. Keep only the most-recently calculated precision, rather
14008 than them all. Record whether each argument has been converted to
14009 string. Use EMACS_INT, not int, for byte and char and arg counts.
14010 Support field widths and precisions larger than INT_MAX. Avoid
14011 sprintf's undefined behavior with conversion specifications such as %#d
14012 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
14013 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
14014 formatting out-of-range floating point numbers with int
14015 formats. (Bug#8668)
14016
14017 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
14018
14019 * data.c: Avoid integer truncation in expressions involving floats.
14020 * data.c: Include <intprops.h>.
14021 (arith_driver): When there's an integer overflow in an expression
14022 involving floating point, convert the integers to floating point
14023 so that the resulting value does not suffer from catastrophic
14024 integer truncation. For example, on a 64-bit host (* 4
14025 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
14026 Do not rely on undefined behavior after integer overflow.
14027
14028 merge count_size_as_multibyte, parse_str_to_multibyte
14029 * character.c, character.h (count_size_as_multibyte):
14030 Rename from parse_str_to_multibyte; all uses changed.
14031 Check for integer overflow.
14032 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
14033 since it's now a duplicate of the other. This is more of
14034 a character than a buffer op, so better that it's in character.c.
14035 * fns.c, print.c: Adjust to above changes.
14036
14037 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
14038
14039 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
14040
14041 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
14042
14043 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14044 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
14045 (x_clipboard_manager_save): Now static.
14046 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
14047
14048 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
14049 (crypto_hash_function): Now static.
14050 Fix pointer signedness problems. Avoid unnecessary initializations.
14051
14052 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
14053
14054 * termhooks.h (Vselection_alist): Make it terminal-local.
14055
14056 * terminal.c (create_terminal): Initialize it.
14057
14058 * xselect.c: Support for clipboard managers.
14059 (Vselection_alist): Move to termhooks.h as terminal-local var.
14060 (LOCAL_SELECTION): New macro.
14061 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
14062 (symbol_to_x_atom): Remove gratuitous arg.
14063 (x_handle_selection_request, lisp_data_to_selection_data)
14064 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
14065 (x_own_selection, x_get_local_selection, x_convert_selection):
14066 New arg, specifying work frame. Use terminal-local Vselection_alist.
14067 (some_frame_on_display): Delete unused function.
14068 (Fx_own_selection_internal, Fx_get_selection_internal)
14069 (Fx_disown_selection_internal, Fx_selection_owner_p)
14070 (Fx_selection_exists_p): New optional frame arg.
14071 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
14072 (x_handle_selection_clear): Don't treat other terminals with the
14073 same keyboard specially. Use the terminal-local Vselection_alist.
14074 (x_clear_frame_selections): Use Frun_hook_with_args.
14075
14076 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
14077
14078 * xterm.h: Add support for those atoms.
14079
14080 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
14081
14082 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
14083 (converted_selections, conversion_fail_tag): New global variables.
14084 (x_selection_request_lisp_error): Free the above.
14085 (x_get_local_selection): Remove unnecessary code.
14086 (x_reply_selection_request): Args changed; handle arbitrary array
14087 of converted selections stored in converted_selections.
14088 Separate the XChangeProperty and SelectionNotify steps.
14089 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
14090 (x_convert_selection): New function.
14091 (x_handle_selection_event): Simplify.
14092 (x_get_foreign_selection): Don't ignore incoming requests while
14093 waiting for an answer; this will fail when we implement
14094 SAVE_TARGETS, and seems unnecessary anyway.
14095 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
14096 (Vx_sent_selection_functions): Doc fix.
14097
14098 2011-05-26 Leo Liu <sdl.web@gmail.com>
14099
14100 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
14101
14102 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14103
14104 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
14105
14106 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
14107 for fringe update if it has periodic bitmap.
14108 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
14109 and fringe_bitmap_periodic_p.
14110
14111 * fringe.c (get_fringe_bitmap_data): New function.
14112 (draw_fringe_bitmap_1, update_window_fringes): Use it.
14113 (update_window_fringes): Record periodicity of fringe bitmap in glyph
14114 row. Mark glyph row for fringe update if periodicity changed.
14115
14116 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
14117 for fringe update unless it has periodic bitmap.
14118
14119 2011-05-25 Kenichi Handa <handa@m17n.org>
14120
14121 * xdisp.c (get_next_display_element): Set correct it->face_id for
14122 a static composition.
14123
14124 2011-05-24 Leo Liu <sdl.web@gmail.com>
14125
14126 * deps.mk (fns.o):
14127 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
14128
14129 * fns.c (crypto_hash_function, Fsha1): New function.
14130 (Fmd5): Use crypto_hash_function.
14131 (syms_of_fns): Add Ssha1.
14132
14133 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14134
14135 * gnutls.c: Remove unused macros.
14136 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
14137 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
14138 Remove macros that are defined and never used.
14139 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
14140
14141 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14142
14143 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
14144 (Fx_get_selection_internal): Minor cleanup.
14145 (Fx_own_selection_internal): Rename arguments for consistency with
14146 select.el.
14147
14148 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
14149
14150 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
14151
14152 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
14153
14154 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
14155
14156 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14157
14158 * dispnew.c (scrolling_window): Don't exclude the case that the
14159 last enabled row in the desired matrix touches the bottom boundary.
14160
14161 2011-05-21 Glenn Morris <rgm@gnu.org>
14162
14163 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
14164 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
14165 and add some more files.
14166
14167 2011-05-20 Eli Zaretskii <eliz@gnu.org>
14168
14169 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
14170 report_file_error introduced by the change from 2011-05-07.
14171
14172 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
14173
14174 * systime.h (Time): Define only if emacs is defined.
14175 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
14176 where the include path doesn't have X11/X.h by default. See
14177 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
14178
14179 2011-05-20 Kenichi Handa <handa@m17n.org>
14180
14181 * composite.c (find_automatic_composition): Fix previous change.
14182
14183 2011-05-20 Glenn Morris <rgm@gnu.org>
14184
14185 * lisp.mk: New file, split from Makefile.in.
14186 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
14187 (shortlisp): Remove.
14188 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
14189
14190 2011-05-19 Glenn Morris <rgm@gnu.org>
14191
14192 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
14193 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
14194 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
14195 (lisp): Set the order to that of loadup.el.
14196 (shortlisp): Make it a copy of $lisp.
14197 (SOME_MACHINE_LISP): Remove.
14198 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
14199 Use just $shortlisp, not $SOME_MACHINE_LISP too.
14200
14201 2011-05-18 Kenichi Handa <handa@m17n.org>
14202
14203 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
14204 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
14205 (find_automatic_composition): Mostly rewrite for efficiency.
14206
14207 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
14208
14209 * makefile.w32-in: Update dependencies.
14210
14211 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
14212
14213 * menu.c: Include limits.h (fixes the MS-Windows build broken by
14214 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
14215
14216 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
14217
14218 Fix some integer overflow issues, such as string length overflow.
14219
14220 * insdel.c (count_size_as_multibyte): Check for string overflow.
14221
14222 * character.c (lisp_string_width): Check for string overflow.
14223 Use EMACS_INT, not int, for string indexes and lengths; in
14224 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
14225 the resulting string length overflows an EMACS_INT; instead,
14226 report a string overflow if no precision given. When checking for
14227 precision exhaustion, use a check that cannot possibly have
14228 integer overflow. (Bug#8675)
14229 * character.h (lisp_string_width): Adjust to new signature.
14230
14231 * alloc.c (string_overflow): New function.
14232 (Fmake_string): Use it. This doesn't change behavior, but saves
14233 a few bytes and will simplify future changes.
14234 * character.c (string_escape_byte8): Likewise.
14235 * lisp.h (string_overflow): New decl.
14236
14237 Fixups, following up to the user-interface timestamp change.
14238 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
14239 for UI timestamps, instead of unsigned long.
14240 * msdos.c (mouse_get_pos): Likewise.
14241 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
14242 * w32gui.h (Time): Define by including "systime.h" rather than by
14243 declaring it ourselves. (Bug#8664)
14244
14245 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
14246 * image.c (clear_image_cache): Likewise.
14247
14248 * term.c (term_mouse_position): Don't assume time_t wraparound.
14249
14250 Be more systematic about user-interface timestamps.
14251 Before, the code sometimes used 'Time', sometimes 'unsigned long',
14252 and sometimes 'EMACS_UINT', to represent these timestamps.
14253 This change causes it to use 'Time' uniformly, as that's what X uses.
14254 This makes the code easier to follow, and makes it easier to catch
14255 integer overflow bugs such as Bug#8664.
14256 * frame.c (Fmouse_position, Fmouse_pixel_position):
14257 Use Time, not unsigned long, for user-interface timestamps.
14258 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
14259 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
14260 * keyboard.h (last_event_timestamp): Likewise.
14261 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
14262 * menu.h (xmenu_show): Likewise.
14263 * term.c (term_mouse_position): Likewise.
14264 * termhooks.h (struct input_event.timestamp): Likewise.
14265 (struct terminal.mouse_position_hook): Likewise.
14266 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
14267 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
14268 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
14269 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
14270 what it was before.
14271 * menu.h, termhooks.h: Include "systime.h", for Time.
14272
14273 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
14274 Don't assume that the difference between two unsigned long values
14275 can fit into an integer. At this point, we know button_down_time
14276 <= event->timestamp, so the difference must be nonnegative, so
14277 there's no need to cast the result if double-click-time is
14278 nonnegative, as it should be; check that it's nonnegative, just in
14279 case. This bug is triggered when events are more than 2**31 ms
14280 apart (about 25 days). (Bug#8664)
14281
14282 * xselect.c (last_event_timestamp): Remove duplicate decl.
14283 (x_own_selection): Remove needless cast to unsigned long.
14284
14285 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
14286 that always fit in int. Use a sentinel instead of a counter, to
14287 avoid a temp and to allay GCC's concerns about possible int overflow.
14288 * frame.h (struct frame): Use int for menu_bar_items_used
14289 instead of EMACS_INT, since it always fits in int.
14290
14291 * menu.c (grow_menu_items): Check for int overflow.
14292
14293 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
14294
14295 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
14296 Before, the code was not consistent. These values cannot exceed
14297 2**31 - 1 so there's no need to make them unsigned.
14298 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
14299 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
14300 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
14301 as modifiers.
14302 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
14303
14304 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
14305 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
14306 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
14307 presumably because the widths might not match.
14308
14309 * window.c (size_window): Avoid needless test at loop start.
14310
14311 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
14312
14313 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
14314
14315 2011-05-12 Drew Adams <drew.adams@oracle.com>
14316
14317 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
14318
14319 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14320
14321 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
14322 `width' to `bar_area_x' and `bar_area_width', respectively.
14323 (x_scroll_run): Take account of fringe background extension.
14324
14325 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
14326 Rename local vars `left' and `width' to `bar_area_x' and
14327 `bar_area_width', respectively.
14328 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
14329 background extension.
14330
14331 2011-05-10 Jim Meyering <meyering@redhat.com>
14332
14333 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
14334
14335 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
14336
14337 * image.c (Finit_image_library): Return t for built-in image types,
14338 like pbm and xbm. (Bug#8640)
14339
14340 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
14341
14342 * w32menu.c (set_frame_menubar): Fix submenu allocation.
14343
14344 2011-05-07 Eli Zaretskii <eliz@gnu.org>
14345
14346 * w32console.c (Fset_screen_color): Doc fix.
14347 (Fget_screen_color): New function.
14348 (syms_of_ntterm): Defsubr it.
14349
14350 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
14351 unlink the temporary file if Fcall_process didn't create it in the
14352 first place.
14353 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
14354 child process will be redirected to a file specified with `:file'.
14355 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
14356 cue to call_process_cleanup not to close that handle.
14357
14358 2011-05-07 Ben Key <bkey76@gmail.com>
14359
14360 * makefile.w32-in: The bootstrap-temacs rule now makes use of
14361 one of two shell specific rules, either bootstrap-temacs-CMD or
14362 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
14363 to the previous implementation of the bootstrap-temacs rule.
14364 The bootstrap-temacs-CMD rule is similar to the previous
14365 implementation of the bootstrap-temacs rule except that it
14366 makes use of the ESC_CFLAGS variable instead of the CFLAGS
14367 variable.
14368
14369 These changes, along with some changes to nt/configure.bat,
14370 nt/gmake.defs, and nt/nmake.defs, are required to extend my
14371 earlier fix to add support for --cflags and --ldflags options
14372 that include quotes so that it works whether make uses cmd or
14373 sh as the shell.
14374
14375 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
14376
14377 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
14378 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
14379 is a constant.
14380 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
14381 a string. Handle both cases.
14382 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
14383 (Fdbus_register_method): Use Qinvalid_function.
14384
14385 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
14386
14387 * makefile.w32-in: Update dependencies.
14388 (LISP_H): Add inttypes.h and stdin.h.
14389 (PROCESS_H): Add unistd.h.
14390
14391 2011-05-06 Eli Zaretskii <eliz@gnu.org>
14392
14393 * lread.c: Include limits.h (fixes the MS-Windows build broken by
14394 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
14395
14396 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
14397
14398 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
14399
14400 * term.c (vfatal): Remove stray call to va_end.
14401 It's not needed and the C Standard doesn't allow it here anyway.
14402
14403 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
14404 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
14405
14406 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
14407 bytes.
14408
14409 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
14410
14411 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
14412
14413 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
14414
14415 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
14416
14417 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
14418
14419 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
14420 * charset.c (Fdefine_charset_internal): Don't initialize
14421 charset.code_space[15]. The value was garbage, on hosts with
14422 32-bit int (Bug#8600).
14423
14424 * lread.c (read_integer): Be more consistent with string-to-number.
14425 Use string_to_number to do the actual conversion; this avoids
14426 rounding errors and fixes some other screwups. Without this fix,
14427 for example, #x1fffffffffffffff was misread as -2305843009213693952.
14428 (digit_to_number): Move earlier, for benefit of read_integer.
14429 Return -1 if the digit is out of range for the base, -2 if it is
14430 not a digit in any supported base. (Bug#8602)
14431
14432 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
14433
14434 * dispnew.c (scrolling_window): Return 1 if we scrolled,
14435 to match comment at start of function. This also removes a
14436 GCC warning about overflow in a 32+64-bit port.
14437
14438 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
14439
14440 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
14441 Reported by Stefan Monnier in
14442 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
14443 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14444 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
14445
14446 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
14447 (EMACS_UINTPTR): Likewise, with uintptr_t.
14448
14449 * lisp.h: Prefer 64-bit EMACS_INT if available.
14450 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
14451 on 32-bit hosts that have 64-bit int, so that they can access
14452 large files.
14453 However, temporarily disable this change unless the temporary
14454 symbol WIDE_EMACS_INT is defined.
14455
14456 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
14457
14458 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
14459 This removes an assumption that EMACS_INT and long are the same
14460 width as pointers. The assumption is true for Emacs porting targets
14461 now, but we want to make other targets possible.
14462 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
14463 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
14464 In the rest of the code, change types of integers that hold casted
14465 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
14466 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
14467 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
14468 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
14469 No need to cast type when ORing.
14470 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
14471 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
14472 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
14473 assume EMACS_INT is the same width as char *.
14474 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
14475 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
14476 Remove no-longer-needed casts.
14477 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
14478 (xg_tool_bar_help_callback, xg_make_tool_item):
14479 Use EMACS_INTPTR to hold an integer
14480 that will be cast to void *; this can avoid a GCC warning
14481 if EMACS_INT is not the same width as void *.
14482 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
14483 * xdisp.c (display_echo_area_1, resize_mini_window_1):
14484 (current_message_1, set_message_1):
14485 Use a local to convert to proper width without a cast.
14486 * xmenu.c (dialog_selection_callback): Likewise.
14487
14488 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
14489 Also, don't assume VALBITS / RAND_BITS is less than 5,
14490 and don't rely on undefined behavior when shifting a 1 left into
14491 the sign bit.
14492 * lisp.h (get_random): Change signature to match.
14493
14494 * lread.c (hash_string): Use size_t, not int, for hash computation.
14495 Normally we prefer signed values; but hashing is special, because
14496 it's better to use unsigned division on hash table sizes so that
14497 the remainder is nonnegative. Also, size_t is the natural width
14498 for hashing into memory. The previous code used 'int', which doesn't
14499 retain enough info to hash well into very large tables.
14500 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
14501
14502 * dbusbind.c: Don't possibly lose pointer info when converting.
14503 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
14504 Use XPNTR rather than XHASH, so that the high-order bits of
14505 the pointer aren't lost when converting through void *.
14506
14507 * eval.c (Fautoload): Don't double-shift a pointer.
14508
14509 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
14510

14543 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
14544 Remove unused parameter `fildes'.
14545 * process.c (read_process_output, send_process): Don't pass it.
14546
14547 2011-05-04 Juanma Barranquero <lekktu@gmail.com>

14634
14635 * sysdep.c (interruptible_wait_for_termination): New function

14647
14648 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of

14679 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
14680
14681 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

14715
14716 Improve `doprnt' and its usage. (Bug#8545)
14717 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
14718 `format_end'. Remove support for %l as a conversion specifier.
14719 Don't use xrealloc. Improve diagnostics when the %l size modifier
14720 is used. Update the commentary.
14721
14722 * eval.c (verror): Simplify calculation of size_t.
14723
14724 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
14725 messages.
14726
14727 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
14728
14729 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
14730 change.
14731
14732 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
14733
14734 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
14735 This makes this file independent of the recent pseudovector change.
14736
14737 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
14738
14739 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
14740
14741 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
14742 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
14743 Remove unused local.
14744 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
14745
14746 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
14747 GCC 4.6.0 optimizes based on type-based alias analysis.
14748 For example, if b is of type struct buffer * and v of type struct
14749 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
14750 != &v->size, and therefore "v->size = 1; b->size = 2; return
14751 v->size;" must therefore return 1. This assumption is incorrect
14752 for Emacs, since it type-puns struct Lisp_Vector * with many other
14753 types. To fix this problem, this patch adds a new type struct
14754 vectorlike_header that documents the constraints on layout of vectors
14755 and pseudovectors, and helps optimizing compilers not get fooled
14756 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
14757 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
14758 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
14759 the size member.
14760 (XSETPVECTYPE): Rewrite in terms of new macro.
14761 (XSETPVECTYPESIZE): New macro, specifying both type and size.
14762 This is a bit clearer, and further avoids the possibility of
14763 undesirable aliasing.
14764 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
14765 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
14766 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
14767 since Lisp_Subr is a special case (no "next" field).
14768 (ASIZE): Now uses header.size rather than size.
14769 All previous uses of XVECTOR (foo)->size replaced to use this macro,
14770 to avoid the hassle of writing XVECTOR (foo)->header.size.
14771 (struct vectorlike_header): New type.
14772 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
14773 object, to help avoid aliasing.
14774 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
14775 (SUBRP): Likewise, since Lisp_Subr is a special case.
14776 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
14777 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
14778 (struct Lisp_Hash_Table): Combine first two members into a single
14779 struct vectorlike_header member. All uses of "size" and "next" members
14780 changed to be "header.size" and "header.next".
14781 * buffer.h (struct buffer): Likewise.
14782 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
14783 * frame.h (struct frame): Likewise.
14784 * process.h (struct Lisp_Process): Likewise.
14785 * termhooks.h (struct terminal): Likewise.
14786 * window.c (struct save_window_data, struct saved_window): Likewise.
14787 * window.h (struct window): Likewise.
14788 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
14789 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
14790 * buffer.c (init_buffer_once): Likewise.
14791 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
14792 special case.
14793 * process.c (Fformat_network_address): Use local var for size,
14794 for brevity.
14795
14796 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
14797
14798 Make the Lisp reader and string-to-float more consistent (Bug#8525)
14799 * data.c (atof): Remove decl; no longer used or needed.
14800 (digit_to_number): Move to lread.c.
14801 (Fstring_to_number): Use new string_to_number function, to be
14802 consistent with how the Lisp reader treats infinities and NaNs.
14803 Do not assume that floating-point numbers represent EMACS_INT
14804 without losing information; this is not true on most 64-bit hosts.
14805 Avoid double-rounding errors, by insisting on integers when
14806 parsing non-base-10 numbers, as the documentation specifies.
14807 * lisp.h (string_to_number): New decl, replacing ...
14808 (isfloat_string): Remove.
14809 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
14810 (read1): Do not accept +. and -. as integers; this
14811 appears to have been a coding error. Similarly, do not accept
14812 strings like +-1e0 as floating point numbers. Do not report
14813 overflow for integer overflows unless the base is not 10 which
14814 means we have no simple and reliable way to continue.
14815 Break out the floating-point parsing into a new
14816 function string_to_number, so that Fstring_to_number parses
14817 floating point numbers consistently with the Lisp reader.
14818 (digit_to_number): Move here from data.c. Make it static inline.
14819 (E_CHAR, EXP_INT): Remove, replacing with ...
14820 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
14821 (string_to_number): New function, replacing isfloat_string.
14822 This function checks for valid syntax and produces the resulting
14823 Lisp float number too. Rework it so that string-to-number
14824 no longer mishandles examples like "1.0e+". Use strtoumax,
14825 so that overflow for non-base-10 numbers is reported only when
14826 there's no portable and simple way to convert to floating point.
14827
14828 * textprop.c (set_text_properties_1): Rewrite for clarity,
14829 and to avoid GCC warning about integer overflow.
14830
14831 * intervals.h (struct interval): Use EMACS_INT for members
14832 where EMACS_UINT might cause problems. See
14833 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
14834 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
14835 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
14836 All uses changed.
14837 (offset_intervals): Tell GCC not to worry about length overflow
14838 when negating a negative length.
14839
14840 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
14841 (overrun_check_free): Likewise.
14842
14843 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
14844 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
14845 word size.
14846
14847 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14848 (gnutls_make_error): Rename local to avoid shadowing.
14849 (gnutls_emacs_global_deinit): ifdef out; not used.
14850 (Fgnutls_boot): Use const for pointer to readonly storage.
14851 Comment out unused local. Fix pointer signedness problems.
14852
14853 * lread.c (openp): Don't stuff size_t into an 'int'.
14854 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
14855 about possible signed overflow.
14856
14857 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
14858 (GDK_KEY_g): Don't define if already defined.
14859 (xg_prepare_tooltip): Avoid pointer signedness problem.
14860 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
14861
14862 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
14863 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
14864
14865 * xfns.c (Fx_window_property): Simplify a bit,
14866 to make a bit faster and to avoid GCC 4.6.0 warning.
14867 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
14868
14869 * fns.c (internal_equal): Don't assume size_t fits in int.
14870
14871 * alloc.c (compact_small_strings): Tighten assertion a little.
14872
14873 Replace pEd with more-general pI, and fix some printf arg casts.
14874 * lisp.h (pI): New macro, generalizing old pEd macro to other
14875 conversion specifiers. For example, use "...%"pI"d..." rather
14876 than "...%"pEd"...".
14877 (pEd): Remove. All uses replaced with similar uses of pI.
14878 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
14879 * alloc.c (check_pure_size): Don't overflow by converting size to int.
14880 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
14881 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
14882 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
14883 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.

14885 64-bit hosts.
14886 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
14887 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
14888 * print.c (safe_debug_print, print_object): Likewise.
14889 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
14890 to int.
14891 Use pI instead of if-then-else-abort. Use %p to avoid casts,
14892 avoiding the 0 flag, which is not portable.
14893 * process.c (Fmake_network_process): Use pI to avoid cast.
14894 * region-cache.c (pp_cache): Likewise.
14895 * xdisp.c (decode_mode_spec): Likewise.
14896 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
14897 behavior on 64-bit hosts with printf arg.

14899 (x_stop_queuing_selection_requests): Likewise.
14900 (x_get_window_property): Don't truncate byte count to an 'int'
14901 when tracing.
14902
14903 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
14904 here, since it parses constructs like leading '-' and spaces,
14905 which are not wanted; and it overflows with large numbers.
14906 Instead, simply match F[0-9]+, which is what is wanted anyway.
14907
14908 * alloc.c: Remove unportable assumptions about struct layout.
14909 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
14910 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
14911 (allocate_vectorlike, make_pure_vector): Use the new macros,
14912 plus offsetof, to remove unportable assumptions about struct layout.
14913 These assumptions hold on all porting targets that I know of, but
14914 they are not guaranteed, they're easy to remove, and removing them
14915 makes further changes easier.
14916
14917 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
14918 This doesn't fix a bug but makes the code clearer.
14919 (string_overrun_cookie): Now const. Use initializers that
14920 don't formally overflow signed char, to avoid warnings.
14921 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
14922 can cause Emacs to crash when string overrun checking is enabled.
14923 (allocate_buffer): Don't assume sizeof (struct buffer) is a
14924 multiple of sizeof (EMACS_INT); it need not be, if
14925 alignof(EMACS_INT) < sizeof (EMACS_INT).
14926 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
14927

14944 matches the current signal symbol.
14945
14946 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
14947
14948 * alloc.c (check_sblock, check_string_bytes)

14956
14957 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
14958 "cast to pointer from integer of different size".
14959
14960 Improve doprnt and its use in verror. (Bug#8545)
14961 * doprnt.c (doprnt): Document the set of format control sequences
14962 supported by the function. Use SAFE_ALLOCA instead of always
14963 using `alloca'.
14964
14965 * eval.c (verror): Don't limit the buffer size at size_max-1, that
14966 is one byte too soon. Don't use xrealloc; instead xfree and
14967 xmalloc anew.
14968
14969 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
14970

14972 callbacks stage.
14973

14975 gnutls_global_initialized. Added internals for the
14976 :verify-hostname-error, :verify-error, and :verify-flags
14977 parameters of `gnutls-boot' and documented those parameters in the
14978 docstring. Start callback support.
14979 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
14980 unless a fatal error occurred. Call gnutls_alert_send_appropriate
14981 on error. Return error code.

15011 * textprop.c (syms_of_textprop): Remove dead code.
15012 (copy_text_properties): Delete obsolete commentary about an

15050 2011-04-23 Eli Zaretskii <eliz@gnu.org>
15051
15052 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
15053 * doprnt.c: Include limits.h.
15054 (SIZE_MAX): New macro.
15055 (doprnt): Return a size_t value. 2nd arg is now size_t.
15056 Many local variables are now size_t instead of int or unsigned.
15057 Improve overflow protection. Support `l' modifier for integer
15058 conversions. Support %l conversion. Don't assume an EMACS_INT
15059 argument for integer conversions and for %c.
15060
15061 * lisp.h (doprnt): Restore prototype.
15062
15063 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

15248
15249 * gnutls.c (Fgnutls_boot): Don't pass Lisp_Object to `error'.

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

15653 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
15654 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
15655 was inaccessible from Lisp.
15656 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
15657 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
15658
15659 alloc.c: Import and export fewer symbols, and remove unused items.
15660 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
15661 is defined.
15662 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
15663 it's not optimized away by whole-program optimization.
15664 (message_enable_multibyte, free_misc): Remove.
15665 (catchlist, handlerlist, mark_backtrace):
15666 Declare only if BYTE_MARK_STACK.
15667 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
15668 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
15669 (message_enable_multibyte): Remove decl.
15670 (free_misc, interval_free_list, float_block, float_block_index):
15671 (n_float_blocks, float_free_list, cons_block, cons_block_index):
15672 (cons_free_list, last_marked_index):
15673 Now static.
15674 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
15675 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
15676 (mark_backtrace): Define only if BYTE_MARK_STACK.
15677 * xdisp.c (message_enable_multibyte): Now static.
15678
15679 Declare Lisp_Object Q* variables to be 'static' if not exported.
15680 This makes it easier for human readers (and static analyzers)
15681 to see whether these variables are used from other modules.
15682 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
15683 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
15684 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
15685 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
15686 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
15687 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
15688 * xmenu.c, xselect.c:
15689 Declare Q* vars static if they are not used in other modules.
15690 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
15691 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
15692 Remove decls of unexported vars.
15693 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
15694
15695 * lisp.h (DEFINE_FUNC): Make sname 'static'.
15696
15697 Make Emacs functions such as Fatom 'static' by default.
15698 This makes it easier for human readers (and static analyzers)
15699 to see whether these functions can be called from other modules.
15700 DEFUN now defines a static function. To make the function external
15701 so that it can be used in other C modules, use the new macro DEFUE.
15702 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
15703 (Finit_image_library):
15704 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
15705 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
15706 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
15707 Remove decls, since these functions are now static.
15708 (Funintern, Fget_internal_run_time): New decls, since these functions
15709 were already external.
15710
15711 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
15712 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
15713 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
15714 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
15715 * keyboard.c, keymap.c, lread.c:
15716 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
15717 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
15718 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
15719 Mark functions with DEFUE instead of DEFUN,
15720 if they are used in other modules.
15721 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
15722 decls for now-static functions.
15723 * buffer.h (Fdelete_overlay): Remove decl.
15724 * callproc.c (Fgetenv_internal): Mark as internal.
15725 * composite.c (Fremove_list_of_text_properties): Remove decl.
15726 (Fcomposition_get_gstring): New forward static decl.
15727 * composite.h (Fcomposite_get_gstring): Remove decl.
15728 * dired.c (Ffile_attributes): New forward static decl.
15729 * doc.c (Fdocumntation_property): New forward static decl.
15730 * eval.c (Ffetch_bytecode): New forward static decl.
15731 (Funintern): Remove extern decl; now in .h file where it belongs.
15732 * fileio.c (Fmake_symbolic_link): New forward static decl.
15733 * image.c (Finit_image_library): New forward static decl.
15734 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
15735 * intervals.h (Fprevious_property_change):
15736 (Fremove_list_of_text_properties): Remove decls.
15737 * keyboard.c (Fthis_command_keys): Remove decl.
15738 (Fcommand_execute): New forward static decl.
15739 * keymap.c (Flookup_key): New forward static decl.
15740 (Fcopy_keymap): Now static.
15741 * keymap.h (Flookup_key): Remove decl.
15742 * process.c (Fget_process): New forward static decl.
15743 (Fprocess_datagram_address): Mark as internal.
15744 * syntax.c (Fsyntax_table_p): New forward static decl.
15745 (skip_chars): Remove duplicate decl.
15746 * textprop.c (Fprevious_property_change): New forward static decl.
15747 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
15748 Now internal.
15749 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
15750 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
15751
15752 * editfns.c (Fformat): Remove unreachable code.
15753
15754 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
15755
15756 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
15757 change. (Bug#8496)
15758
15759 2011-04-13 Eli Zaretskii <eliz@gnu.org>
15760
15761 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
15762 when at ZV. (Bug#8487)
15763
15764 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
15765
15766 * charset.c (Fclear_charset_maps): Use xfree instead of free.
15767 (Bug#8437)
15768 * keyboard.c (parse_tool_bar_item): Likewise.
15769 * sound.c (sound_cleanup, alsa_close): Likewise.
15770 * termcap.c (tgetent): Likewise.
15771 * xfns.c (x_default_font_parameter): Likewise.
15772 * xsettings.c (read_and_apply_settings): Likewise.
15773
15774 * alloc.c (overrun_check_malloc, overrun_check_realloc)
15775 (overrun_check_free): Protoize.
15776
15777 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
15778
15779 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
15780 since callers should never pass a negative size.
15781 Change the signature to match that of plain 'read' and 'write'; see
15782 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
15783 * lisp.h: Update prototypes of emacs_write and emacs_read.
15784
15785 2011-04-11 Eli Zaretskii <eliz@gnu.org>
15786
15787 * xdisp.c (redisplay_window): Don't try to determine the character
15788 position of the scroll margin if the window start point w->startp
15789 is outside the buffer's accessible region. (Bug#8468)
15790
15791 2011-04-10 Eli Zaretskii <eliz@gnu.org>
15792
15793 Fix write-region and its subroutines for buffers > 2GB.
15794 * fileio.c (a_write, e_write): Modify declaration of arguments and
15795 local variables to support buffers larger than 2GB.
15796 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
15797
15798 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
15799 argument, local variables, and return value.
15800
15801 * lisp.h: Update prototypes of emacs_write and emacs_read.
15802
15803 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
15804
15805 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
15806
15807 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
15808
15809 Fix more problems found by GCC 4.6.0's static checks.
15810
15811 * xdisp.c (vmessage): Use a better test for character truncation.
15812
15813 * charset.c (load_charset_map): <, not <=, for optimization,
15814 and to avoid potential problems with integer overflow.
15815 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
15816 * casetab.c (set_identity, shuffle): Likewise.
15817 * editfns.c (Fformat): Likewise.
15818 * syntax.c (skip_chars): Likewise.
15819
15820 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
15821 This also lets GCC 4.6.0 generate slightly better loop code.
15822
15823 * callint.c (Fcall_interactively): <, not <=, for optimization.
15824 (Fcall_interactively): Count the number of arguments produced,
15825 not the number of arguments given. This is simpler and lets GCC
15826 4.6.0 generate slightly better code.
15827
15828 * ftfont.c: Distingish more carefully between FcChar8 and char.
15829 The previous code passed unsigned char * to a functions like
15830 strlen and xstrcasecmp that expect char *, which does not
15831 conform to the C standard.
15832 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
15833 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
15834 char * when the C standard requires it.
15835
15836 * keyboard.c (read_char): Remove unused var.
15837
15838 * eval.c: Port to Windows vsnprintf (Bug#8435).
15839 Include <limits.h>.
15840 (SIZE_MAX): Define if the headers do not.
15841 (verror): Do not give up if vsnprintf returns a negative count.
15842 Instead, grow the buffer. This ports to Windows vsnprintf, which
15843 does not conform to C99. Problem reported by Eli Zaretskii.
15844 Also, simplify the allocation scheme, by avoiding the need for
15845 calling realloc, and removing the ALLOCATED variable.
15846
15847 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
15848
15849 Remove invocations of doprnt, as Emacs now uses vsnprintf.
15850 But keep the doprint source code for now, as we might revamp it
15851 and use it again (Bug#8435).
15852 * lisp.h (doprnt): Remove.
15853 * Makefile.in (base_obj): Remove doprnt.o.
15854 * deps.mk (doprnt.o): Remove.
15855
15856 error: Print 32- and 64-bit integers portably (Bug#8435).
15857 Without this change, on typical 64-bit hosts error ("...%d...", N)
15858 was used to print both 32- and 64-bit integers N, which relied on
15859 undefined behavior.
15860 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
15861 * lisp.h (error, verror): Mark as printf-like functions.
15862 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
15863 Report overflow in size calculations when allocating printf buffer.
15864 Do not truncate output string at its first null byte.
15865 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
15866 Truncate the output at a character boundary, since vsnprintf does not
15867 do that.
15868 * charset.c (check_iso_charset_parameter): Convert internal
15869 character to string before calling 'error', since %c now has the
15870 printf meaning.
15871 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
15872 overflow when computing char to be passed to 'error'. Do not
15873 pass Lisp_Object to 'error'; pass the integer instead.
15874 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
15875 formatted with plain %d.
15876
15877 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
15878
15879 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
15880
15881 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
15882
15883 * xterm.c (x_catch_errors): Remove duplicate declaration.
15884
15885 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
15886
15887 * xdisp.c, lisp.h (message_nolog): Remove; unused.
15888
15889 2011-04-10 Jim Meyering <meyering@redhat.com>
15890
15891 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
15892 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
15893 return ssize_t not "int", and use size_t as the buffer length.
15894 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
15895 * gnutls.h: Update declarations.
15896 * process.c (read_process_output): Use ssize_t, to match.
15897 (send_process): Likewise.
15898
15899 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15900
15901 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
15902
15903 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
15904
15905 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
15906 Use unsigned char, to match FcChar8 type definition.
15907
15908 * xterm.c (handle_one_xevent):
15909 * xmenu.c (create_and_show_popup_menu):
15910 * xselect.c (x_decline_selection_request)
15911 (x_reply_selection_request): Avoid type-punned deref of X events.
15912
15913 2011-04-09 Eli Zaretskii <eliz@gnu.org>
15914
15915 Fix some uses of `int' instead of EMACS_INT.
15916 * search.c (string_match_1, fast_string_match)
15917 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
15918 (scan_buffer, find_next_newline_no_quit)
15919 (find_before_next_newline, search_command, Freplace_match)
15920 (Fmatch_data): Make some `int' variables be EMACS_INT.
15921
15922 * xdisp.c (display_count_lines): 3rd argument and return value now
15923 EMACS_INT. All callers changed.
15924 (pint2hrstr): Last argument is now EMACS_INT.
15925
15926 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
15927 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
15928 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
15929 (decode_coding_utf_16, decode_coding_emacs_mule)
15930 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
15931 (decode_coding_ccl, decode_coding_charset)
15932 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
15933 (decode_coding_iso_2022, decode_coding_emacs_mule)
15934 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
15935 <char_offset, last_offset>: Declare EMACS_INT.
15936 (encode_coding_utf_8, encode_coding_utf_16)
15937 (encode_coding_emacs_mule, encode_invocation_designation)
15938 (encode_designation_at_bol, encode_coding_iso_2022)
15939 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
15940 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
15941 Declare EMACS_INT.
15942 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
15943 (encode_invocation_designation): Last argument P_NCHARS is now
15944 EMACS_INT.
15945 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
15946 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
15947
15948 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
15949 All users changed.
15950
15951 * ccl.c (Fccl_execute_on_string): Declare some variables
15952 EMACS_INT.
15953
15954 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
15955
15956 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
15957
15958 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
15959
15960 * process.c (Fformat_network_address): Doc fix.
15961
15962 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
15963
15964 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
15965
15966 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
15967
15968 * keyboard.c (read_char): Call Lisp function help-form-show,
15969 instead of using internal_with_output_to_temp_buffer.
15970 (Qhelp_form_show): New var.
15971 (syms_of_keyboard): Use DEFSYM macro.
15972
15973 * print.c (internal_with_output_to_temp_buffer): Function deleted.
15974
15975 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
15976
15977 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
15978
15979 * process.c (Flist_processes): Remove to Lisp.
15980 (list_processes_1): Delete.
15981
15982 2011-04-06 Eli Zaretskii <eliz@gnu.org>

15984 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
15985
15986 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
15987
15988 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
15989
15990 Fix more problems found by GCC 4.6.0's static checks.
15991
15992 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
15993
15994 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
15995
15996 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
15997
15998 * xdisp.c (vmessage): Mark as a printf-like function.
15999
16000 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
16001
16002 * sound.c (sound_warning): Don't crash if arg contains a printf format.
16003
16004 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
16005 printf-like functions.
16006 (tiff_load): Add casts to remove these marks before passing them
16007 to system-supplied API.
16008
16009 * eval.c (Fsignal): Remove excess argument to 'fatal'.
16010
16011 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
16012 This avoids several warnings with gcc -Wstrict-overflow.
16013 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
16014 directly, rather than having caller test rule sign. This avoids
16015 some unnecessary tests.
16016 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
16017 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
16018 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
16019
16020 * xfont.c (xfont_text_extents): Remove var that was set but not used.
16021 (xfont_open): Avoid unnecessary tests.
16022
16023 * composite.c (composition_gstring_put_cache): Use unsigned integer.
16024
16025 * composite.h, composite.c (composition_gstring_put_cache):
16026 Use EMACS_INT, not int, for length.
16027
16028 * composite.h (COMPOSITION_DECODE_REFS): New macro,
16029 breaking out part of COMPOSITION_DECODE_RULE.
16030 (COMPOSITION_DECODE_RULE): Use it.
16031 * composite.c (get_composition_id): Remove unused local vars,
16032 by using the new macro.
16033
16034 * textprop.c (set_text_properties_1): Change while to do-while,
16035 since the condition is always true at first.
16036
16037 * intervals.c (graft_intervals_into_buffer): Mark var as used.
16038 (interval_deletion_adjustment): Return unsigned value.
16039 All uses changed.
16040
16041 * process.c (list_processes_1, create_pty, read_process_output):
16042 (exec_sentinel): Remove vars that were set but not used.
16043 (create_pty): Remove unnecessary "volatile"s.
16044 (Fnetwork_interface_info): Avoid possibility of int overflow.
16045 (read_process_output): Do adaptive read buffering even if carryover.

16047
16048 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
16049
16050 * syntax.c (scan_words): Remove var that was set but not used.
16051 (update_syntax_table): Use unsigned instead of int.
16052
16053 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
16054 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
16055 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
16056
16057 * print.c (print_error_message): Avoid int overflow.
16058
16059 * font.c (font_list_entities): Redo for clarity,
16060 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
16061
16062 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
16063 (font_score): Avoid potential overflow in diff calculation.
16064
16065 * fns.c (substring_both): Remove var that is set but not used.
16066 (sxhash): Redo loop for clarity and to avoid wraparound warning.
16067
16068 * eval.c (funcall_lambda): Rename local to avoid shadowing.
16069
16070 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
16071 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
16072 can always succeed if overflow has undefined behavior.
16073
16074 * search.c (boyer_moore, wordify): Remove vars set but not used.
16075 (wordify): Omit three unnecessary tests.
16076
16077 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

16079
16080 * casefiddle.c (casify_region): Remove var that is set but not used.
16081
16082 * dired.c (file_name_completion): Remove var that is set but not used.
16083
16084 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
16085
16086 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
16087 (Finsert_file_contents): Remove unnecessary code checking fd.

16090 Check for integer overflow on size calculations.
16091
16092 * buffer.c (Fprevious_overlay_change): Remove var that is set
16093 but not used.
16094

16104
16105 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
16106 that are set but not used.
16107
16108 * xfns.c (make_invisible_cursor): Don't return garbage
16109 if XCreateBitmapFromData fails (Bug#8410).
16110
16111 * xselect.c (x_get_local_selection, x_handle_property_notify):
16112 Remove vars that are set but not used.
16113
16114 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
16115 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
16116
16117 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
16118 Remove var that is set but not used.
16119 (scroll_bar_windows_size): Now size_t, not int.
16120 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
16121 Check for overflow.
16122
16123 * xfaces.c (realize_named_face): Remove vars that are set but not used.
16124 (map_tty_color) [!defined MSDOS]: Likewise.
16125
16126 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
16127
16128 * coding.c: Remove vars that are set but not used.
16129 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
16130 All callers changed.
16131 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
16132 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
16133 (decode_coding_charset): Remove vars that are set but not used.
16134
16135 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
16136 that is set but not used.
16137
16138 * print.c (print_object): Remove var that is set but not used.
16139
16140 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
16141 The gnulib version avoids calling malloc in the usual case,
16142 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
16143 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
16144 * filelock.c (current_lock_owner): Likewise.
16145 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
16146 * sysdep.c: Include allocator.h, careadlinkat.h.
16147 (emacs_no_realloc_allocator): New static constant.
16148 (emacs_readlink): New function.
16149 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
16150 ../lib/careadlinkat.h.
16151
16152 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
16153
16154 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
16155 first non-nil return value).
16156
16157 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
16158
16159 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
16160 if not defined (Bug#8403).
16161
16162 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16163
16164 * xdisp.c (display_count_lines): Remove parameter `start',
16165 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16166 (get_char_face_and_encoding): Remove parameter `multibyte_p',
16167 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
16168 (fill_stretch_glyph_string): Remove parameters `row' and `area',
16169 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk

16176 do not dereference NULL upon failed strdup
16177 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
16178 (ns_get_family): Likewise.
16179
16180 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
16181
16182 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
16183
16184 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
16185
16186 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
16187 later (Bug#8403).
16188
16189 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
16190
16191 Add lexical binding.
16192
16193 * window.c (Ftemp_output_buffer_show): New fun.
16194 (Fsave_window_excursion):
16195 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
16196
16197 * lread.c (lisp_file_lexically_bound_p): New function.
16198 (Fload): Bind Qlexical_binding.
16199 (readevalloop): Remove `evalfun' arg.
16200 Bind Qinternal_interpreter_environment.
16201 (Feval_buffer): Bind Qlexical_binding.
16202 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
16203 Mark as dynamic.
16204 (syms_of_lread): Declare `lexical-binding'.
16205
16206 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
16207
16208 * keyboard.c (eval_dyn): New fun.
16209 (menu_item_eval_property): Use it.
16210
16211 * image.c (parse_image_spec): Use Ffunctionp.
16212
16213 * fns.c (concat, mapcar1): Accept byte-code-functions.
16214
16215 * eval.c (Fsetq): Handle lexical vars.
16216 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
16217 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
16218 (FletX, Flet): Obey lexical binding.
16219 (Fcommandp): Handle closures.
16220 (Feval): New `lexical' arg.
16221 (eval_sub): New function extracted from Feval. Use it almost
16222 everywhere where Feval was used. Look up vars in lexical env.
16223 Handle closures.
16224 (Ffunctionp): Move from subr.el.
16225 (Ffuncall): Handle closures.
16226 (apply_lambda): Remove `eval_flags'.
16227 (funcall_lambda): Handle closures and new byte-code-functions.
16228 (Fspecial_variable_p): New function.
16229 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
16230 but without exporting it to Lisp.
16231
16232 * doc.c (Fdocumentation, store_function_docstring):
16233 * data.c (Finteractive_form): Handle closures.
16234
16235 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
16236 interactive spec.
16237
16238 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
16239 New byte-codes.
16240 (exec_byte_code): New function extracted from Fbyte_code to handle new
16241 calling convention for byte-code-functions. Add new byte-codes.
16242
16243 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
16244
16245 * alloc.c (Fmake_symbol): Init new `declared_special' field.
16246
16247 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
16248
16249 * xdisp.c (redisplay_internal): Fix prototype.
16250
16251 2011-03-31 Eli Zaretskii <eliz@gnu.org>
16252
16253 * xdisp.c (SCROLL_LIMIT): New macro.
16254 (try_scrolling): Use it when setting scroll_limit.
16255 Limit scrolling to 100 screen lines.
16256 (redisplay_window): Even when falling back on "recentering",
16257 position point in the window according to scroll-conservatively,
16258 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
16259
16260 (try_scrolling): When point is above the window, allow searching
16261 as far as scroll_max, or one screenful, to compute vertical
16262 distance from PT to the scroll margin position. This prevents
16263 try_scrolling from unnecessarily failing when
16264 scroll-conservatively is set to a value slightly larger than the
16265 window height. Clean up the case of PT below the margin at bottom
16266 of window: scroll_max can no longer be INT_MAX. When aggressive
16267 scrolling is in use, don't let point enter the opposite scroll
16268 margin as result of the scroll.
16269 (syms_of_xdisp) <scroll-conservatively>: Document the
16270 threshold of 100 lines for never-recentering scrolling.
16271
16272 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

16274 * dispextern.h (move_it_by_lines):
16275 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
16276 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
16277 (message_log_check_duplicate): Remove parameters `prev_bol' and
16278 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
16279 (redisplay_internal): Remove parameter `preserve_echo_area',
16280 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
16281
16282 * indent.c (Fvertical_motion):
16283 * window.c (window_scroll_pixel_based, Frecenter):
16284 Don't pass `need_y_p' to `move_it_by_lines'.
16285
16286 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
16287
16288 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
16289 steal a few bits to be more compact.
16290 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
16291 Remove unneeded casts.
16292
16293 * bytecode.c (Fbyte_code): CAR and CDR can GC.
16294
16295 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
16296
16297 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
16298 binding" message (bug#7967).
16299
16300 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
16301
16302 Fix more problems found by GCC 4.6.0's static checks.
16303
16304 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
16305 Remove unused local var.
16306
16307 * editfns.c (Fmessage_box): Remove unused local var.
16308
16309 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
16310 (note_mode_line_or_margin_highlight, note_mouse_highlight):
16311 Omit unused local vars.
16312 * window.c (shrink_windows): Omit unused local var.
16313 * menu.c (digest_single_submenu): Omit unused local var.
16314 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
16315 Omit unused local var.
16316
16317 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
16318 Don't assume string length fits in int.
16319 (keyremap_step, read_key_sequence): Use size_t for sizes.
16320 (read_key_sequence): Don't check last_real_key_start redundantly.
16321
16322 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
16323 instead of alloca (Bug#8344).
16324
16325 * eval.c (Fbacktrace): Don't assume nargs fits in int.
16326 (Fbacktrace_frame): Don't assume nframes fits in int.
16327
16328 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
16329
16330 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
16331 concerns.
16332
16333 * term.c (produce_glyphless_glyph): Remove unnecessary test.
16334
16335 * cm.c (calccost): Turn while-do into do-while, for clarity.
16336
16337 * keyboard.c (syms_of_keyboard): Use the same style as later
16338 in this function when indexing through an array. This also
16339 works around GCC bug 48267.
16340
16341 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
16342
16343 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
16344
16345 * chartab.c (sub_char_table_ref_and_range): Redo for slight
16346 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
16347
16348 * keyboard.c, keyboard.h (num_input_events): Now size_t.
16349 This avoids undefined behavior on integer overflow, and is a bit
16350 more convenient anyway since it is compared to a size_t variable.
16351
16352 Variadic C functions now count arguments with size_t, not int.
16353 This avoids an unnecessary limitation on 64-bit machines, which
16354 caused (substring ...) to crash on large vectors (Bug#8344).
16355 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
16356 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
16357 All variadic functions and their callers changed accordingly.
16358 (struct gcpro.nvars): Now size_t, not int. All uses changed.
16359 * data.c (arith_driver, float_arith_driver): Likewise.
16360 * editfns.c (general_insert_function): Likewise.
16361 * eval.c (struct backtrace.nargs, interactive_p)
16362 (internal_condition_case_n, run_hook_with_args, apply_lambda)
16363 (funcall_lambda, mark_backtrace): Likewise.
16364 * fns.c (concat): Likewise.
16365 * frame.c (x_set_frame_parameters): Likewise.
16366 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
16367 0 if not found, not -1. All callers changed.
16368
16369 * alloc.c (garbage_collect): Don't assume stack size fits in int.
16370 (stack_copy_size): Now size_t, not int.
16371 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
16372

16377 All callers changed.
16378
16379 * lisp.h (multibyte_char_to_unibyte):
16380 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
16381 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
16382 * character.h (CHAR_TO_BYTE8):
16383 * cmds.c (internal_self_insert):
16384 * editfns.c (general_insert_function):
16385 * keymap.c (push_key_description):
16386 * search.c (Freplace_match):
16387 * xdisp.c (message_dolog, set_message_1): All callers changed.
16388
16389 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
16390
16391 * keyboard.c (safe_run_hook_funcall): New function.
16392 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
16393 don't set the hook to nil, but remove the offending function instead.
16394 (Qcommand_hook_internal): Remove, unused.
16395 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
16396 Vcommand_hook_internal.
16397
16398 * eval.c (enum run_hooks_condition): Remove.
16399 (funcall_nil, funcall_not): New functions.
16400 (run_hook_with_args): Call each function through a `funcall' argument.
16401 Remove `cond' argument, now redundant.
16402 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
16403 (Frun_hook_with_args_until_failure): Adjust accordingly.
16404 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

16423 used outside xdisp.c).
16424 (cursor_row_p): Remove parameter `w', unused since

16583
16584 Fix more problems found by GCC 4.5.2's static checks.
16585
16586 * coding.c (encode_coding_raw_text): Avoid unnecessary test
16587 the first time through the loop, since we know p0 < p1 then.
16588 This also avoids a gcc -Wstrict-overflow warning.
16589
16590 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
16591 leading to a memory leak, possible in functions like
16592 load_charset_map_from_file that can allocate an unbounded number
16593 of objects (Bug#8318).
16594
16595 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
16596 that could (at least in theory) be that large.
16597
16598 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
16599 This is less likely to overflow, and avoids undefined behavior if
16600 overflow does occur. All callers changed. Use strtoul to scan
16601 for the unsigned long integer.
16602 (pint2hrstr): Simplify and tune code slightly.
16603 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
16604

16614 fail (Bug#8306).
16615
16616 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
16617
16618 * process.c (Fmake_network_process): Use socklen_t, not int,
16619 where POSIX says socklen_t is required in portable programs.
16620 This fixes a porting bug on hosts like 64-bit HP-UX, where
16621 socklen_t is wider than int (Bug#8277).
16622 (Fmake_network_process, server_accept_connection):
16623 (wait_reading_process_output, read_process_output):
16624 Likewise.
16625

16633 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
16634 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
16635
16636 Make tparam.h and terminfo.c consistent.
16637 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
16638 Include tparam.h instead, since it declares them.
16639 * cm.h (PC): Remove extern decl; tparam.h now does this.
16640 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
16641 * terminfo.c: Include tparam.h, to check interfaces.
16642 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
16643 (tparam): Adjust signature to match interface in tparam.h;
16644 this removes some undefined behavior. Check that outstring and len
16645 are zero, which they always are with Emacs.
16646 * tparam.h (PC, BC, UP): New extern decls.
16647
16648 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

16657 Rename locals to avoid shadowing.
16658
16659 * xfont.c (xfont_list_family): Mark var as initialized.
16660
16661 * xml.c (make_dom): Now static.
16662
16663 * composite.c (composition_compute_stop_pos): Rename local to
16664 avoid shadowing.
16665 (composition_reseat_it): Remove unused locals.
16666 (find_automatic_composition, composition_adjust_point): Likewise.
16667 (composition_update_it): Mark var as initialized.
16668 (find_automatic_composition): Mark vars as initialized,
16669 with a FIXME (Bug#8290).
16670
16671 character.h: Rename locals to avoid shadowing.
16672 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):

16674 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
16675 (BUF_DEC_POS): Be more systematic about renaming local temporaries
16676 to avoid shadowing.
16677

16679
16680 * intervals.c (interval_start_pos): Now static.
16681
16682 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
16683

16685 Rename locals to avoid shadowing.
16686
16687 * sound.c (wav_play, au_play, Fplay_sound_internal):
16688 Fix pointer signedness.
16689 (alsa_choose_format): Remove unused local var.
16690 (wav_play): Initialize a variable to 0, to prevent undefined
16691 behavior (Bug#8278).
16692
16693 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
16694
16695 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
16696
16697 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
16698 clobbering (Bug#8298).
16699 * sysdep.c (sys_subshell): Likewise.
16700 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
16701
16702 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
16703 This should get cleaned up, so that child_setup has the
16704 same signature on all platforms.
16705
16706 * callproc.c (call_process_cleanup): Now static.
16707 (relocate_fd): Rename locals to avoid shadowing.

16709 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
16710
16711 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
16712 not to be necessary, and produces flickering.

16716 * config.in: Remove file.

16721 are now in src/globals.h.
16722 (syms_of_minibuf): Remove spurious & from previous change.
16723
16724 2011-03-20 Leo Liu <sdl.web@gmail.com>

16748 (sigchld_handler): Now static.
16749
16750 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
16751 That way, the code declares only the vars that it needs.

16768 n rather than nn, a way that does not involve shadowing.
16769 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
16770
16771 * deps.mk (unexalpha.o): Remove; unused.

16828 * callint.c (quotify_arg, quotify_args): Now static.
16829 (Fcall_interactively): Rename locals to avoid shadowing.
16830 Use const pointer when appropriate.
16831
16832 * lisp.h (get_system_name, get_operating_system_release):
16833 Move decls here, to check interfaces.
16834 * process.c (get_operating_system_release): Move decl to lisp.h.
16835 * xrdb.c (get_system_name): Likewise.
16836 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
16837 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
16838 some of which prompt warnings from gcc -Wbad-function-cast.
16839 (Fformat_time_string, Fencode_time, Finsert_char):
16840 (Ftranslate_region_internal, Fformat):
16841 Rename or remove local vars to avoid shadowing.
16842 (Ftranslate_region_internal): Mark var as initialized.
16843
16844 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
16845 avoid shadowing.
16846
16847 * lisp.h (eassert): Check that the argument compiles, even if
16848 ENABLE_CHECKING is not defined.
16849
16850 * data.c (Findirect_variable): Name an expression, to avoid
16851 gcc -Wbad-function-cast warning.
16852 (default_value, arithcompare, arith_driver, arith_error): Now static.
16853 (store_symval_forwarding): Rename local to avoid shadowing.
16854 (Fmake_variable_buffer_local, Fmake_local_variable):
16855 Mark variables as initialized.
16856 (do_blv_forwarding, do_symval_forwarding): Remove; unused.
16857
16858 * alloc.c (check_cons_list): Do not define unless GC_CHECK_CONS_LIST.
16859 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
16860 Rename locals to avoid shadowing.
16861 (mark_stack): Move local variables into the #ifdef region where
16862 they're used.
16863 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
16864 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
16865 needed otherwise.
16866 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
16867 (GC_STRING_CHARS): Remove; not used.
16868 (Fmemory_limit): Cast sbrk's returned value to char *.
16869
16870 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
16871 avoids undefined behavior in theory.
16872
16873 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
16874
16875 Use functions, not macros, for up- and down-casing (Bug#8254).
16876 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16877 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
16878 to use the following functions instead of these macros.
16879 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
16880 EMACS_INT, since callers assume the returned value fits in int.
16881 (upcase1): Likewise, for UPCASE_TABLE.
16882 (uppercasep, lowercasep, upcase): New static inline functions.
16883 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

16887 Rename locals to avoid shadowing.
16888 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
16889 (regex_compile, re_search_2, re_match_2_internal):
16890 Remove unused local vars.
16891 (FREE_VAR): Rewrite so as not to use empty "else",
16892 which gcc can warn about.
16893 (regex_compile, re_match_2_internal): Mark locals as initialized.
16894 (RETALLOC_IF): Define only if needed.
16895 (WORDCHAR_P): Likewise. This one is never needed, but is used
16896 only in a comment talking about a compiler bug, so put inside
16897 the #if 0 of that comment.
16898 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
16899 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
16900 Remove; unused.
16901
16902 * search.c (boyer_moore): Rename locals to avoid shadowing.
16903 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
16904 (PREV_CHAR_BOUNDARY): Likewise.
16905
16906 * search.c (simple_search): Remove unused var.
16907
16908 * dired.c (compile_pattern): Move decl from here ...
16909 * lisp.h: ... to here, so that it can be checked.
16910 (struct re_registers): New forward decl.
16911
16912 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
16913
16914 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
16915 All uses changed.
16916 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
16917 Rename locals to avoid shadowing.
16918 (Fvertical_motion): Mark locals as initialized.
16919
16920 * casefiddle.c (casify_object, casify_region): Now static.
16921 (casify_region): Mark local as initialized.
16922
16923 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
16924
16925 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
16926 New macros, so that the caller can use some names other than
16927 gcpro1, gcpro2, etc.
16928 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
16929 of the new macros.
16930 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
16931 argument, for consistency with GCPRO2_VAR, etc: it is now the
16932 prefix of the variable, not the variable itself. All uses
16933 changed.
16934 * dired.c (directory_files_internal, file_name_completion):
16935 Rename locals to avoid shadowing.
16936
16937 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
16938 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
16939 dired.c's scmp function, had undefined behavior.
16940 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
16941 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
16942 * buffer.h: ... to here, because these macros use current_buffer,
16943 and the new implementation with inline functions needs to have
16944 current_buffer in scope now, rather than later when the macros
16945 are used.
16946 (downcase, upcase1): New static inline functions.
16947 (DOWNCASE, UPCASE1): Reimplement using these functions.
16948 This avoids undefined behavior in expressions like
16949 DOWNCASE (x) == DOWNCASE (y), which previously suffered
16950 from race conditions in accessing the global variables
16951 case_temp1 and case_temp2.
16952 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
16953 * lisp.h (case_temp1, case_temp2): Remove their decls.
16954 * character.h (ASCII_CHAR_P): Move from here ...
16955 * lisp.h: ... to here, so that the inline functions mentioned
16956 above can use them.
16957
16958 * dired.c (directory_files_internal_unwind): Now static.
16959
16960 * fileio.c (file_name_as_directory, directory_file_name):
16961 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
16962 Now static.
16963 (file_name_as_directory): Use const pointers when appropriate.
16964 (Fexpand_file_name): Likewise. In particular, newdir might
16965 point at constant storage, so make it a const pointer.
16966 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
16967 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
16968 signedness issues.
16969 (Fset_file_times, Finsert_file_contents, auto_save_error):
16970 Rename locals to avoid shadowing.
16971
16972 * minibuf.c (choose_minibuf_frame_1): Now static.
16973 (Ftry_completion, Fall_completions): Rename or remove locals
16974 to avoid shadowing.
16975
16976 * marker.c (bytepos_to_charpos): Remove; unused.
16977
16978 * lisp.h (verify_bytepos, count_markers): New decls,
16979 so that gcc does not warn that these functions aren't declared.
16980
16981 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
16982 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
16983 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
16984 (copy_text): Remove unused local var.
16985
16986 * filelock.c (within_one_second): Now static.
16987 (lock_file_1): Rename local to avoid shadowing.
16988
16989 * buffer.c (fix_overlays_before): Mark locals as initialized.
16990 (fix_start_end_in_overlays): Likewise. This function should be
16991 simplified by using pointers-to-pointers, but that's a different
16992 matter.
16993 (switch_to_buffer_1): Now static.
16994 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
16995 (report_overlay_modification): Rename locals to avoid shadowing.
16996
16997 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
16998 Fix pointer signedness issue.
16999 (sys_subshell): Mark local as volatile if checking for lint,
17000 to suppress a gcc -Wclobbered warning that does not seem to be right.
17001 (MAXPATHLEN): Define only if needed.
17002
17003 * process.c (serial_open, serial_configure): Move decls from here ...
17004 * systty.h: ... to here, so that they can be checked.
17005
17006 * fns.c (get_random, seed_random): Move extern decls from here ...
17007 * lisp.h: ... to here, so that they can be checked.
17008
17009 * sysdep.c (reset_io): Now static.
17010 (wait_for_termination_signal): Remove; unused.
17011
17012 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
17013 (copy_keymap_item, append_key, push_text_char_description):
17014 Now static.
17015 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
17016 (DENSE_TABLE_SIZE): Remove; unused.
17017 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
17018 (describe_map_tree):
17019 Rename locals to avoid shadowing.
17020
17021 * keyboard.c: Declare functions static if they are not used elsewhere.
17022 (echo_char, echo_dash, cmd_error, top_level_2):
17023 (poll_for_input, handle_async_input): Now static.

17031
17032 * keyboard.h (make_ctrl_char): New decl.
17033 (mark_kboards): Move decl here ...
17034 * alloc.c (mark_kboards): ... from here.
17035
17036 * lisp.h (force_auto_save_soon): New decl.
17037
17038 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
17039 (DEFINE_DUMMY_FUNCTION): New macro.
17040 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
17041 Use it.
17042 (main): Add casts to avoid warnings
17043 if GCC considers string literals to be constants.
17044
17045 * lisp.h (fatal_error_signal): Add decl, since it's exported.
17046
17047 * dbusbind.c: Pointer signedness fixes.
17048 (xd_signature, xd_append_arg, xd_initialize):
17049 (Fdbus_call_method, Fdbus_call_method_asynchronously):

17168 For example, without this patch (encode-time 0 0 0 1 1
17169 1152921504606846976) returns the obviously-bogus value (-948597
17170 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
17171 reports time overflow. See

17184 (Fencode_time): Use it, to test for out-of-range times.
17185 (lisp_time_argument): Don't rely on undefined left-shift and
17186 right-shift behavior when checking for time stamp overflow.
17187
17188 * editfns.c (time_overflow): New function, refactoring common code.
17189 (Fformat_time_string, Fdecode_time, Fencode_time):
