2
3 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p

90
912011-08-14 Jan Djärv <jan.h.d@swipnet.se>
92
93 * nsterm.h (ns_run_ascript): Declare.

100 the event loop. Get status from as_status (Bug#7276).
101
102 * nsterm.m (sendEvent): If event is NSApplicationDefined and
103 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
104 the event loop (Bug#7276).
105
1062011-08-14 Andreas Schwab <schwab@linux-m68k.org>
107
108 * gnutls.c (QCgnutls_bootprop_priority)
109 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
110 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
111 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
112 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
113 (QCgnutls_bootprop_verify_hostname_error)
114 (QCgnutls_bootprop_callbacks_verify): Rename from
115 Qgnutls_bootprop_..., all uses changed.
116
117 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
118 uses changed.
119
1202011-08-14 Paul Eggert <eggert@cs.ucla.edu>
121
122 * xfaces.c (Qframe_set_background_mode): Now static.
123 * dispextern.h (Qframe_set_background_mode): Remove decl.
124
125 * process.c (Fnetwork_interface_info): Declare local only if needed.
126
1272011-08-13 Jan Djärv <jan.h.d@swipnet.se>
128
129 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
130 (Fnetwork_interface_list): Allocate in increments of bytes instead
131 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
132 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
133 sockaddr.
134 (struct ifflag_def): notrailers is smart on OSX.
135 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
136 Get hardware address with getifaddrs if available.
137
1382011-08-12 Eli Zaretskii <eliz@gnu.org>
139
140 * xdisp.c (iterate_out_of_display_property): xassert that
141 IT->position is set to within IT->object's boundaries. Break from
142 the loop as soon as EOB is reached; avoids infloops in redisplay
143 when IT->position is set up wrongly due to some bug. Set
144 IT->current to match the bidi iterator unconditionally.
145 (push_display_prop): Allow GET_FROM_STRING as IT->method on
146 entry. Force push_it to save on the stack the current
147 buffer/string position, to be restored by pop_it. Fix flags in
148 the iterator structure wrt the object coming from a display
149 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
150 properties. (Bug#9284)
151
1522011-08-09 Andreas Schwab <schwab@linux-m68k.org>
153
154 * fontset.c (fontset_get_font_group): Add proper type checks.
155 (Bug#9172)
156
1572011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
158
159 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
160 and LC_VERSION_MIN_MACOSX.
161 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
162 (dump_it) [LC_FUNCTION_STARTS]: Use it.
163
1642011-08-08 Eli Zaretskii <eliz@gnu.org>
165
166 * xdisp.c (forward_to_next_line_start): Allow to use the
167 no-display-properties-and-no-overlays under bidi display. Set
168 disp_pos in the bidi iterator to avoid searches for display
169 properties and overlays.
170
1712011-08-08 Chong Yidong <cyd@stupidchicken.com>
172
173 * editfns.c (Fset_time_zone_rule): Document relationship with the
174 setenv function.
175
176 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
177 the font entity extracted from the cache (Bug#8109).
178
1792011-08-07 Chong Yidong <cyd@stupidchicken.com>
180
181 * composite.c (autocmp_chars): Don't reset point. That is done by
182 restore_point_unwind (Bug#5984).
183
1842011-08-07 Juri Linkov <juri@jurta.org>
185
186 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
187 to show the arg `TIME' instead of `TIMEVAL'.
188
1892011-08-06 Eli Zaretskii <eliz@gnu.org>
190
191 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
192 display property strides EOL and includes a newline, as in
193 longlines-mode. (Bug#9254)
194 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
195 word-wrap under bidirectional display. (Bug#9224)
196
197 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
198 is non-zero, even if the data buffer is NULL. Fixes a crash in
199 vertical-motion with longlines-mode. (Bug#9254)
200
2012011-08-05 Eli Zaretskii <eliz@gnu.org>
202
203 * bidi.c <bidi_cache_total_alloc>: Now static.
204 (bidi_initialize): Initialize bidi_cache_total_alloc.
205
206 *xdisp.c (display_line): Release buffer allocated for shelved bidi
207 cache. (Bug#9221)
208
209 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
210 amount allocated this far in `bidi_cache_total_alloc'.
211 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
212 non-zero, only free the data buffer without restoring the cache
213 contents. All callers changed.
214
215 * dispextern.h (bidi_unshelve_cache): Update prototype.
216
217 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
218 (move_it_in_display_line, move_it_to)
219 (move_it_vertically_backward, move_it_by_lines): Replace the call
220 to xfree to an equivalent call to bidi_unshelve_cache.
221 (move_it_in_display_line_to): Fix logic of returning
222 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
223
2242011-08-05 Eli Zaretskii <eliz@gnu.org>
225
226 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
227 came from a string character with a `cursor' property. (Bug#9229)
228
2292011-08-04 Jan Djärv <jan.h.d@swipnet.se>
230
231 * Makefile.in (LIB_PTHREAD): New variable.
232 (LIBES): Add LIB_PTHREAD (Bug#9216).
233
234 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
235 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
236
2372011-08-04 Andreas Schwab <schwab@linux-m68k.org>
238
239 * regex.c (re_iswctype): Remove some redundant boolean
240 conversions.
241
2422011-08-04 Jan Djärv <jan.h.d@swipnet.se>
243
244 * xterm.c (x_find_topmost_parent): New function.
245 (x_set_frame_alpha): Find topmost parent window with
246 x_find_topmost_parent and set the property there also (bug#9181).
247 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
248
2492011-08-04 Paul Eggert <eggert@cs.ucla.edu>
250
251 * callproc.c (Fcall_process): Avoid vfork clobbering
252 the local vars buffer, coding_systems, current_dir.
253
2542011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
255
256 * keymap.c (Fmake_composed_keymap): Move to subr.el.
257
2582011-08-03 Paul Eggert <eggert@cs.ucla.edu>
259
260 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
261 so that it is not optimized away.
262
263 * xdisp.c (compute_display_string_pos): Remove unused local.
264
2652011-08-02 Eli Zaretskii <eliz@gnu.org>
266
267 Fix slow cursor motion and scrolling in large buffers with
268 selective display, like Org Mode buffers. (Bug#9218)
269
270 * dispextern.h (struct bidi_it): New member disp_prop_p.
271
272 * xdisp.c: Remove one-slot cache of display string positions.
273 (compute_display_string_pos): Accept an additional argument
274 DISP_PROP_P; callers changed. Scan at most 5K characters forward
275 for a display string or property. If found, set DISP_PROP_P
276 non-zero.
277
278 * bidi.c (bidi_fetch_char): Accept an additional argument
279 DISP_PROP_P, and pass it to compute_display_string_pos.
280 Only handle text covered by a display string if DISP_PROP_P is returned
281 non-zero. All callers of bidi_fetch_char changed.
282
2832011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
284
285 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
286
2872010-12-03 Don March <don@ohspite.net>
288
289 * keymap.c (Fdefine_key): Fix non-prefix key error message when
290 last character M-[char] is translated to ESC [char] (bug#7541).
291
2922011-08-02 Kenichi Handa <handa@m17n.org>
293
294 * lisp.h (uniprop_table): Extern it.
295
296 * chartab.c (uniprop_table): Make it non-static.
297
2982011-08-01 Eli Zaretskii <eliz@gnu.org>
299
300 * xdisp.c (forward_to_next_line_start): Accept additional argument
301 BIDI_IT_PREV, and store into it the state of the bidi iterator had
302 on the newline.
303 (reseat_at_next_visible_line_start): Use the bidi iterator state
304 returned by forward_to_next_line_start to restore the state of
305 it->bidi_it after backing up to previous newline. (Bug#9212)
306
3072011-07-30 Andreas Schwab <schwab@linux-m68k.org>
308
309 * regex.c (re_comp): Protoize.
310 (re_exec): Fix return type.
311 (regexec): Fix type of `ret'. (Bug#9203)
312
3132011-07-29 Paul Eggert <eggert@cs.ucla.edu>
314
315 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
316 This is needed if max-image-size is a floating-point number.
317
3182011-07-28 Andreas Schwab <schwab@linux-m68k.org>
319
320 * print.c (print_object): Print empty symbol as ##.
321
322 * lread.c (read1): Read ## as empty symbol.
323
3242011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
325
326 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
327 setting frame foreground color (Bug#9175).
328 (x_set_background_color): Likewise.
329
330 * nsmenu.m (-setText): Size tooltip dimensions precisely to
331 contents (Bug#9176).
332 (EmacsTooltip -init): Remove bezels and add shadows to
333 tooltip windows.
334
335 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
336 or scroll bar (Bug#8470).
337
338 * nsfont.m (nsfont_open): Remove assignment to voffset and
339 unnecessary vars hshink, expand, hd, full_height, min_height.
340 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
341
342 * nsterm.h (nsfont_info): Remove voffset field.
343
3442011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
345
346 Implement strike-through and overline on NextStep (Bug#8863).
347
348 * nsfont.m (nsfont_open): Use underline position provided by font,
349 instead of hard-coded value of 2.
350 (nsfont_draw): Call ns_draw_text_decoration instead.
351
352 * nsterm.h: Add declaration for ns_draw_text_decoration.
353
354 * nsterm.m (ns_draw_text_decoration): New function for drawing
355 underline, overline, and strike-through.
356 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
357 ns_draw_text_decoration. Change treatment of cursor drawing to
358 accomodate underlining, etc.
359
3602011-07-28 Eli Zaretskii <eliz@gnu.org>
361
362 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
363 default.
364
3652011-07-28 Paul Eggert <eggert@cs.ucla.edu>
366
367 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
368 Without this fix, if a signal arrives just after memory fills up,
369 'malloc' might be invoked reentrantly.
370
371 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
372 In other words, assume that every image size is allowed, on non-X
373 hosts. This assumption is probably wrong, but it lets Emacs compile.
374
3752011-07-28 Andreas Schwab <schwab@linux-m68k.org>
376
377 * regex.c (re_iswctype): Convert return values to boolean.
378
3792011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
380
381 * xdisp.c (compute_display_string_pos): Don't use cached display
382 string position if the buffer had its restriction changed.
383 (Bug#9184)
384
3852011-07-28 Paul Eggert <eggert@cs.ucla.edu>
386
387 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
388
3892011-07-28 Paul Eggert <eggert@cs.ucla.edu>
390
391 Integer signedness and overflow and related fixes. (Bug#9079)
392
393 * bidi.c: Integer size and overflow fixes.
394 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
395 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
396 (bidi_cache_find_level_change, bidi_cache_ensure_space)
397 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
398 (bidi_find_other_level_edge):
399 Use ptrdiff_t instead of EMACS_INT where either will do.
400 This works better on 32-bit hosts configured --with-wide-int.
401 (bidi_cache_ensure_space): Check for size-calculation overflow.
402 Use % rather than repeated addition, for better worst-case speed.
403 Don't set bidi_cache_size until after xrealloc returns, because it
404 might not return.
405 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
406 (bidi_cache_ensure_space): Also check that the bidi cache size
407 does not exceed that of the largest Lisp string or buffer. See Eli
408 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
409
410 * alloc.c (__malloc_size_t): Remove.
411 All uses replaced by size_t. See Andreas Schwab's note
412 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
413
414 * image.c: Improve checking for integer overflow.
415 (check_image_size): Assume that f is nonnull, since
416 it is always nonnull in practice. This is one less thing to
417 worry about when checking for integer overflow later.
418 (x_check_image_size): New function, which checks for integer
419 overflow issues inside X.
420 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
421 This removes the need for a memory_full check.
422 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
423 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
424 (xbm_read_bitmap_data): Change locals back to 'int', since
425 their values must fit in 'int'.
426 (xpm_load_image, png_load, tiff_load):
427 Invoke x_create_x_image_and_pixmap earlier,
428 to avoid much needless work if the image is too large.
429 (tiff_load): Treat overly large images as if
430 x_create_x_image_and_pixmap failed, not as malloc failures.
431 (gs_load): Use x_check_image_size.
432
433 * gtkutil.c: Omit integer casts.
434 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
435 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
436
437 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
438
439 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
440 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
441 would wrongly return t on a 64-bit host.
442
443 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
444 The plain *_OVERFLOW macros run afoul of GCC bug 49705
445 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
446 and therefore cause GCC to emit a bogus diagnostic in some cases.
447
448 * image.c: Integer signedness and overflow and related fixes.
449 This is not an exhaustive set of fixes, but it's time to
450 record what I've got.
451 (lookup_pixel_color, check_image_size): Remove redundant decls.
452 (check_image_size): Don't assume that arbitrary EMACS_INT values
453 fit in 'int', or that arbitrary 'double' values fit in 'int'.
454 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
455 (tiff_load, imagemagick_load_image):
456 Check for overflow in size calculations.
457 (x_create_x_image_and_pixmap): Remove unnecessary test for
458 xmalloc returning NULL; that can't happen.
459 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
460 (xpm_color_bucket): Use better integer hashing function.
461 (xpm_cache_color): Don't possibly over-allocate memory.
462 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
463 (gif_memory_source):
464 Use ptrdiff_t, not int or size_t, to record sizes.
465 (png_load): Don't assume values greater than 2**31 fit in 'int'.
466 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
467 either works, as we prefer signed integers.
468 (tiff_read_from_memory, tiff_write_from_memory):
469 Return tsize_t, not size_t, since that's what the TIFF API wants.
470 (tiff_read_from_memory): Don't fail simply because the read would
471 go past EOF; instead, return a short read.
472 (tiff_load): Omit no-longer-needed casts.
473 (Fimagemagick_types): Don't assume size fits into 'int'.
474
475 Improve hashing quality when configured --with-wide-int.
476 * fns.c (hash_string): New function, taken from sxhash_string.
477 Do not discard information about ASCII character case; this
478 discarding is no longer needed.
479 (sxhash-string): Use it. Change sig to match it. Caller changed.
480 * lisp.h: Declare it.
481 * lread.c (hash_string): Remove, since we now use fns.c's version.
482 The fns.c version returns a wider integer if --with-wide-int is
483 specified, so this should help the quality of the hashing a bit.
484
485 * emacs.c: Integer overflow minor fix.
486 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
487 Define only if GNU_LINUX.
488 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
489
490 * dispnew.c: Integer signedness and overflow fixes.
491 Remove unnecessary forward decls, that were a maintenance hassle.
492 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
493 All uses changed.
494 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
495 (scrolling_window): Use ptrdiff_t, not int, for byte count.
496 (prepare_desired_row, line_draw_cost):
497 Use int, not unsigned, where either works.
498 (save_current_matrix, restore_current_matrix):
499 Use ptrdiff_t, not size_t, where either works.
500 (init_display): Check for overflow more accurately, and without
501 relying on undefined behavior.
502
503 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
504 Remove, replacing with the new symbols in lisp.h. All uses changed.
505 * fileio.c (make_temp_name):
506 * filelock.c (lock_file_1, lock_file):
507 * xdisp.c (message_dolog):
508 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
509 Use pMd etc. instead.
510 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
511 replacing the pWIDE etc. symbols removed from editfns.c.
512
513 * keyboard.h (num_input_events): Now uintmax_t.
514 This is (very slightly) less likely to mess up due to wraparound.
515 All uses changed.
516
517 * buffer.c: Integer signedness fixes.
518 (alloc_buffer_text, enlarge_buffer_text):
519 Use ptrdiff_t rather than size_t when either will do, as we prefer
520 signed integers.
521
522 * alloc.c: Integer signedness and overflow fixes.
523 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
524 (__malloc_size_t): Default to size_t, not to int.
525 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
526 (Fgarbage_collect, mark_object_loop_halt, mark_object):
527 Prefer ptrdiff_t to size_t when either would do, as we prefer
528 signed integers.
529 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
530 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
531 Now const. Initialize with values that are in range even if char
532 is signed.
533 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
534 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
535 These functions do the right thing with sizes > 2**32.
536 (check_depth): Now ptrdiff_t, not int.
537 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
538 Adjust to new way of storing sizes. Check for size overflow bugs
539 in rest of code.
540 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
541 slightly wrong anyway, as it missed one instance of
542 XMALLOC_OVERRUN_CHECK_OVERHEAD.
543 (refill_memory_reserve): Omit needless cast to size_t.
544 (mark_object_loop_halt): Mark as externally visible.
545
546 * xselect.c: Integer signedness and overflow fixes.
547 (Fx_register_dnd_atom, x_handle_dnd_message):
548 Use ptrdiff_t, not size_t, since we prefer signed.
549 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
550 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
551 x_dnd_atoms_size and x_dnd_atoms_length.
552
553 * doprnt.c: Prefer signed to unsigned when either works.
554 * eval.c (verror):
555 * doprnt.c (doprnt):
556 * lisp.h (doprnt):
557 * xdisp.c (vmessage):
558 Use ptrdiff_t, not size_t, when using or implementing doprnt,
559 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
560 prefer signed arithmetic to avoid comparison confusion.
561 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
562 but is a bit tricky.
563
564 Assume freestanding C89 headers, string.h, stdlib.h.
565 * data.c, doprnt.c, floatfns.c, print.c:
566 Include float.h unconditionally.
567 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
568 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
569 * regex.c: Likewise for stddef.h, string.h.
570 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
571 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
572 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
573 (STDC_HEADERS): Remove obsolete defines.
574 * sysdep.c: Include limits.h unconditionally.
575
576 Assume support for memcmp, memcpy, memmove, memset.
577 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
578 * regex.c (memcmp, memcpy):
579 Remove; we assume C89 now.
580
581 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
582 (__malloc_safe_bcopy): Remove; no longer needed.
583
584 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
585 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
586 well either way, and we prefer signed to unsigned.
587
5882011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
589
590 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
591 closes the connection while we're reading (bug#9182).
592
5932011-07-25 Jan Djärv <jan.h.d@swipnet.se>
594
595 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
596 are specified (Bug#9168).
597
5982011-07-25 Paul Eggert <eggert@cs.ucla.edu>
599
600 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
601 Found by GCC static checking and --with-wide-int on a 32-bit host.
602
6032011-07-25 Eli Zaretskii <eliz@gnu.org>
604
605 * xdisp.c (compute_display_string_pos): Fix logic of caching
606 previous display string position. Initialize cached_prev_pos to
607 -1. Fixes slow-down at the beginning of a buffer.
608
6092011-07-24 Eli Zaretskii <eliz@gnu.org>
610
611 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
612 for attrs[LFACE_FONTSET_INDEX].
613
6142011-07-23 Paul Eggert <eggert@cs.ucla.edu>
615
616 * xml.c (parse_region): Remove unused local
617 that was recently introduced.
618
6192011-07-23 Eli Zaretskii <eliz@gnu.org>
620
621 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
622 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
623
624 * xdisp.c (move_it_in_display_line_to): Record the best matching
625 position for TO_CHARPOS while scanning the line, and restore it on
626 exit if none of the characters scanned was an exact match.
627 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
628 when exact match is impossible due to invisible text, and the
629 lines are truncated.
630
6312011-07-23 Jan Djärv <jan.h.d@swipnet.se>
632
633 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
634 for OSX >= 10.7.
635
6362011-07-22 Eli Zaretskii <eliz@gnu.org>
637
638 Fix a significant slow-down of cursor motion with C-n, C-p,
639 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
640 auto-repeat under bidi redisplay in fontified buffers.
641 * xdisp.c (compute_stop_pos_backwards): New function.
642 (next_element_from_buffer): Call compute_stop_pos_backwards to
643 find a suitable prev_stop when we find ourselves before
644 base_level_stop.
645 (reseat): Don't look for prev_stop, as that could mean a very long
646 run.
647 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
648 <cached_disp_overlay_modiff>: Cache for last found display string
649 position.
650 (compute_display_string_pos): Return the cached position if asked
651 about the same buffer in the same area of character positions, and
652 the buffer wasn't changed since the time the display string
653 position was cached.
654
6552011-07-22 Eli Zaretskii <eliz@gnu.org>
656
657 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
658 is an integer, which is important for empty lines. (Bug#9149)
659
6602011-07-22 Chong Yidong <cyd@stupidchicken.com>
661
662 * frame.c (Fmodify_frame_parameters): In tty case, update the
663 default face if necessary (Bug#4238).
664
6652011-07-21 Chong Yidong <cyd@stupidchicken.com>
666
667 * editfns.c (Fstring_to_char): No need to explain what a character
668 is in the docstring (Bug#6576).
669
6702011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
671
672 * xml.c (parse_region): Make sure we always return a tree.
673
6742011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
675
676 * xml.c (parse_region): If a document contains only comments,
677 return that, too.
678
6792011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
680
681 * xml.c (make_dom): Return comments, too.
682
6832011-07-19 Paul Eggert <eggert@cs.ucla.edu>
684
685 Port to OpenBSD.
686 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
687 and the surrounding thread.
688 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
689 rather than fgets, and retry after EINTR. Otherwise, 'emacs
690 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
691 timer goes off.
692 * s/openbsd.h (BROKEN_SIGIO): Define.
693 * unexelf.c (unexec) [__OpenBSD__]:
694 Don't update the .mdebug section of the Alpha COFF symbol table.
695
6962011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
697
698 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
699 (bug#8460).
700
7012011-07-18 Paul Eggert <eggert@cs.ucla.edu>
702
703 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
704 This fixes some race conditions on the permissions of any newly
705 created file.
706
707 * alloc.c (valid_pointer_p): Use pipe, not open.
708 This fixes some permissions issues when debugging.
709
710 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
711 If fchown fails to set both uid and gid, try to set just gid,
712 as that is sometimes allowed. Adjust the file's mode to eliminate
713 setuid or setgid bits that are inappropriate if fchown fails.
714
7152011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
716
717 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
718 to compare Lisp_Objects.
719 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
720 global_gnutls_log_level, don't mistake it for a Lisp_Object.
721 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
722
7232011-07-17 Andreas Schwab <schwab@linux-m68k.org>
724
725 * lread.c (read_integer): Unread even EOF character.
726 (read1): Likewise. Properly record start position of symbol.
727
728 * lread.c (read1): Read `#:' as empty uninterned symbol if no
729 symbol character follows.
730
7312011-07-17 Paul Eggert <eggert@cs.ucla.edu>
732
733 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
734 This works around a problem with the previous change to Fcopy_file.
735 Recent glibc declares fchown with __attribute__((warn_unused_result)),
736 and without this change, GCC might complain about discarding
737 fchown's return value.
738
7392011-07-16 Juanma Barranquero <lekktu@gmail.com>
740
741 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
742
7432011-07-16 Paul Eggert <eggert@cs.ucla.edu>
744
745 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
746
7472011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
748
749 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
750 it's used from the C level.
751
752 * process.c: Use the same condition for POLL_FOR_INPUT in both
753 keyboard.c and process.c (bug#1858).
754
7552011-07-09 Lawrence Mitchell <wence@gmx.li>
756
757 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
758 (Fgnutls_boot): Use it.
759
7602011-07-15 Andreas Schwab <schwab@linux-m68k.org>
761
762 * doc.c (Fsubstitute_command_keys): Revert last change.
763
7642011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
765
766 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
767 quotes the next character, and doesn't affect other longer
768 sequences (bug#8935).
769
770 * lread.c (syms_of_lread): Clarify that is isn't only
771 `eval-buffer' and `eval-defun' that's affected by
772 `lexical-binding' (bug#8460).
773
7742011-07-15 Eli Zaretskii <eliz@gnu.org>
775
776 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
777 bidi redisplay when a line includes both an image and is
778 truncated.
779
7802011-07-14 Paul Eggert <eggert@cs.ucla.edu>
781
782 Fix minor problems found by static checking.
783 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
784 (elsz): Now a signed constant, not a size_t var. We prefer signed
785 types to unsigned, to avoid integer comparison confusion. Without
786 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
787 "cannot optimize loop, the loop counter may overflow", a symptom
788 of the confusion.
789 * indent.c (Fvertical_motion): Mark locals as initialized.
790 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
791
7922011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
793
794 * search.c (Fre_search_backward): Mention `case-fold-search' in
795 all the re_search_* functions (bug#8138).
796
797 * keyboard.c (Fopen_dribble_file): Document when the file is
798 closed (bug#8056).
799
8002011-07-14 Eli Zaretskii <eliz@gnu.org>
801
802 * bidi.c (bidi_dump_cached_states): Fix format of displaying
803 bidi_cache_idx.
804
805 Support bidi reordering of display and overlay strings.
806 * xdisp.c (compute_display_string_pos)
807 (compute_display_string_end): Accept additional argument STRING.
808 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
809 (reseat_to_string): Initialize bidi_it->string.s and
810 bidi_it->string.schars.
811 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
812 NULL (avoids a crash in bidi_paragraph_init).
813 Initialize itb.string.lstring.
814 (init_iterator): Call bidi_init_it only of a valid
815 buffer position was specified. Initialize paragraph_embedding to
816 L2R.
817 (reseat_to_string): Initialize the bidi iterator.
818 (display_string): If we need to ignore text properties of
819 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
820 original value of -1 will not work with bidi.)
821 (compute_display_string_pos): First arg is now struct
822 `text_pos *'; all callers changed. Support display properties on
823 Lisp strings.
824 (compute_display_string_end): Support display properties on Lisp
825 strings.
826 (init_iterator, reseat_1, reseat_to_string): Initialize the
827 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
828 when iterating on a string not from display properties).
829 (compute_display_string_pos, compute_display_string_end):
830 Fix calculation of the object to scan. Fixes an error when using
831 arrow keys.
832 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
833 base_level_stop; instead, set base_level_stop to BEGV.
834 Fixes crashes in vertical-motion.
835 (next_element_from_buffer): Improve commentary for when
836 the iterator is before prev_stop.
837 (init_iterator): Initialize bidi_p from the default value of
838 bidi-display-reordering, not from buffer-local value. Use the
839 buffer-local value only if initializing for buffer iteration.
840 (handle_invisible_prop): Support invisible properties on strings
841 that are being bidi-reordered.
842 (set_iterator_to_next): Support bidi reordering of C strings and
843 Lisp strings.
844 (next_element_from_string): Support bidi reordering of Lisp
845 strings.
846 (handle_stop_backwards): Support Lisp strings as well.
847 (display_string): Support display of R2L glyph rows.
848 Use IT_STRING_CHARPOS when displaying from a Lisp string.
849 (init_iterator): Don't initialize it->bidi_p for strings
850 here.
851 (reseat_to_string): Initialize it->bidi_p for strings here.
852 (next_element_from_string, next_element_from_c_string)
853 (next_element_from_buffer): Add xassert's for correspondence
854 between IT's object being iterated and it->bidi_it.string
855 structure.
856 (face_before_or_after_it_pos): Support bidi iteration.
857 (next_element_from_c_string): Handle the case of the first string
858 character that is not the first one in the visual order.
859 (get_visually_first_element): New function, refactored from common
860 parts of next_element_from_buffer, next_element_from_string, and
861 next_element_from_c_string.
862 (tool_bar_lines_needed, redisplay_tool_bar)
863 (display_menu_bar): Force left-to-right direction. Add a FIXME
864 comment for making that be controlled by a user option.
865 (push_it, pop_it): Save and restore the state of the
866 bidi iterator. Save and restore the bidi_p flag.
867 (pop_it): Iterate out of display property for string iteration as
868 well.
869 (iterate_out_of_display_property): Support iteration over strings.
870 (handle_single_display_spec): Set up it->bidi_it for iteration
871 over a display string, and call bidi_init_it.
872 (handle_single_display_spec, next_overlay_string)
873 (get_overlay_strings_1, push_display_prop): Set up the bidi
874 iterator for displaying display or overlay strings.
875 (forward_to_next_line_start): Don't use the shortcut if
876 bidi-iterating.
877 (back_to_previous_visible_line_start): If handle_display_prop
878 pushed the iterator stack, restore the internal state of the bidi
879 iterator by calling bidi_pop_it same number of times.
880 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
881 and we are bidi-iterating, don't decrement the iterator position;
882 instead, set the first_elt flag in the bidi iterator, to produce
883 the same effect.
884 (reseat_1): Remove redundant setting of string_from_display_prop_p.
885 (push_display_prop): xassert that we are iterating a buffer.
886 (push_it, pop_it): Save and restore paragraph_embedding member.
887 (handle_single_display_spec, next_overlay_string)

1308 Remove unportable assumption about struct layout (Bug#8884).
1309 * alloc.c (mark_buffer):
1310 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
1311 (clone_per_buffer_values): Don't assume that
1312 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
1313 This isn't true in general, and it's particularly not true
1314 if Emacs is configured with --with-wide-int.
1315 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
1316 New macros, used in the buffer.c change.

1348 Add comment.
1349
13502011-07-05 Paul Eggert <eggert@cs.ucla.edu>
1351
1352 Random fixes. E.g., (random) never returned negative values.
1353 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
1354 subseconds part to the entropy, as that's a bit more random.
1355 Prefer signed to unsigned, since the signedness doesn't matter and
1356 in general we prefer signed. When given a limit, use a
1357 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
1358 latter isn't right if USE_2_TAGS_FOR_INTS.
1359 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
1360 not 0..VALMASK. Don't discard "excess" bits that random () returns.
1361

1367 * w32fns.c (syms_of_w32fns):
1368 * xfns.c (syms_of_xfns): Don't Add `display' since it's there by default.
1369
13702011-07-04 Paul Eggert <eggert@cs.ucla.edu>
1371
1372 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
1373 This is more efficient than Ffile_directory_p and avoids a minor race.
1374
13752011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
1376
1377 * buffer.c (Foverlay_put): Say what the return value is
1378 (bug#7835).
1379

1396
1397 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
1398 (syms_of_gnutls): Remove duplicate DEFSYM for
1399 Qgnutls_bootprop_verify_hostname_error, an error for
1400 Qgnutls_bootprop_verify_error (which is no longer used).
1401
1402 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
1403 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
1404 Also (re)move comments that are misplaced or no longer relevant.
1405
14062011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
1407

1429 leave any prefix arg for the up event (Bug#1586).
1430
14312011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
1432

1460 (Fcopy_keymap): Handle embedded parents.
1461 (Fcommand_remapping, define_as_prefix): Simplify.

1486 (emacs_settings_set_property, emacs_settings_class_init)
1487 (emacs_settings_init, gsettings_obj): Remove.

1504
1505 * eval.c (struct backtrace): Simplify and port the data structure.
1506 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
1507 signed bit field, as this assumption is not portable and it makes
1508 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
1509 "char debug_on_exit : 1" as this is not portable either; instead,
1510 use the portable "unsigned int debug_on_exit : 1". Remove unused
1511 member evalargs. Remove obsolete comments about cc bombing out.
1512
15132011-06-30 Jan Djärv <jan.h.d@swipnet.se>

1556 the overlay's window property doesn't match the current window.
1557
1558 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.
1559 (Fwindow_hchild): Rename to Fwindow_left_child.

1728 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
1729 The following patches are for when GLYPH_DEBUG && !XASSERT.
1730 * dispextern.h (trace_redisplay_p, dump_glyph_string):
1731 * dispnew.c (flush_stdout):
1732 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
1733 Mark as externally visible.
1734 * dispnew.c (check_window_matrix_pointers): Now static.
1735 * dispnew.c (window_to_frame_vpos):
1736 * xfns.c (unwind_create_frame):
1737 * xterm.c (x_check_font): Remove unused local.
1738 * scroll.c (CHECK_BOUNDS):
1739 * xfaces.c (cache_fache): Rename local to avoid shadowing.
1740 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
1741 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
1742 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
1743 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
1744 Now static.
1745 (debug_method_add): Use va_list and vsprintf rather than relying
1746 on undefined behavior with wrong number of arguments.
1747 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
1748 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
1749 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
1750 since we're not interested in debugging glyphs with old libraries.
1751 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
1752 GCC 4.6.0's static checking.
1753

1768 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
1769 (.bitmaps_last):
1770 * xfaces.c (load_pixmap):
1771 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
1772 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
1773 (.bitmaps_last, struct x_output.icon_bitmap):
1774 Use ptrdiff_t, not int, for bitmap indexes.
1775 (x_allocate_bitmap_record): Check for size overflow.
1776 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
1777
1778 Use ptrdiff_t, not int, for overlay counts.
1779 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
1780 * editfns.c (overlays_around, get_pos_property):
1781 * textprop.c (get_char_property_and_overlay):
1782 * xdisp.c (next_overlay_change, note_mouse_highlight):
1783 * xfaces.c (face_at_buffer_position):
1784 * buffer.c (OVERLAY_COUNT_MAX): New macro.
1785 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
1786 (Fnext_overlay_change, Fprevious_overlay_change)
1787 (mouse_face_overlay_overlaps, Foverlays_in):
1788 Use ptrdiff_t, not int, for sizes.
1789 (overlays_at, overlays_in): Check for size-calculation overflow.
1790
1791 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
1792
1793 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
1794 (x_session_initialize): Do not assume string length fits in int.
1795
1796 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
1797 This is unlikely, but can occur if DPI is outlandish.
1798
1799 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
1800 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
1801
1802 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
1803 * xrdb.c (magic_file_p, search_magic_path):
1804 Omit last arg SUFFIX; it was always 0. All callers changed.
1805 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
1806
1807 * xfont.c (xfont_match): Avoid need for strlen.
1808
1809 * xfns.c: Don't assume strlen fits in int.
1810 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
1811
1812 * xdisp.c (message_log_check_duplicate): Return intmax_t,
1813 not unsigned long, as we prefer signed integers. All callers changed.
1814 Detect integer overflow in repeat count.
1815 (message_dolog): Don't assume print length fits in 39 bytes.
1816 (display_mode_element): Don't assume strlen fits in int.
1817
1818 * termcap.c: Don't assume sizes fit in int and never overflow.
1819 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
1820 (gobble_line): Check for size-calculation overflow.
1821
1822 * minibuf.c (Fread_buffer):
1823 * lread.c (intern, intern_c_string):
1824 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
1825 Don't assume string length fits in int.
1826
1827 * keyboard.c (parse_tool_bar_item):
1828 * gtkutil.c (style_changed_cb): Avoid need for strlen.
1829
1830 * font.c: Don't assume string length fits in int.
1831 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
1832 Use ptrdiff_t, not int.
1833 (font_intern_prop): Don't assume string length fits in int.
1834 Don't assume integer property fits in fixnum.
1835 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
1836
1837 * filelock.c: Fix some buffer overrun and integer overflow issues.
1838 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
1839 Reformulate so as not to need the command string.
1840 Invoke gzip -cd rather than gunzip, as it's more portable.
1841 (lock_info_type, lock_file_1, lock_file):
1842 Don't assume pid_t and time_t fit in unsigned long.
1843 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
1844 (current_lock_owner): Prefer signed type for sizes.
1845 Use memcpy, not strncpy, where memcpy is what is really wanted.
1846 Don't assume (via atoi) that time_t and pid_t fit in int.
1847 Check for time_t and/or pid_t out of range, e.g., via a network share.
1848 Don't alloca where an auto var works fine.
1849
1850 * fileio.c: Fix some integer overflow issues.
1851 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
1852 Don't assume string length fits in int.
1853 (directory_file_name): Don't assume string length fits in long.
1854 (make_temp_name): Don't assume pid fits in int, or that its print
1855 length is less than 20.
1856
1857 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
1858
1859 * coding.c (make_subsidiaries): Don't assume string length fits in int.
1860
1861 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
1862
1863 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
1864 We prefer signed integers, even for size calculations.
1865
1866 * emacs.c: Don't assume string length fits in 'int'.
1867 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
1868 (main): Don't invoke strlen when not needed.
1869
1870 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
1871 (XD_DEBUG_MESSAGE): Don't waste a byte.
1872
1873 * callproc.c (getenv_internal_1, getenv_internal)
1874 (Fgetenv_internal):
1875 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
1876
1877 * lread.c (invalid_syntax): Omit length argument.
1878 All uses changed. This doesn't fix a bug, but it simplifies the
1879 code away from its former Hollerith-constant appearance, and it's
1880 one less 'int' to worry about when looking at integer-overflow issues.
1881 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
1882
1883 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
1884 This didn't break anything, but it didn't help either.
1885 It's confusing to put a bogus integer in a place where the actual
1886 value does not matter.
1887 (LIST_END_P): Remove unused macro and its bogus comment.
1888 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
1889
1890 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
1891 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
1892 implementation.
1893 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
1894 We prefer signed types, and the value cannot exceed the EMACS_INT
1895 range anyway (because otherwise the length would not be representable).
1896 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
1897 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
1898 This avoids a GCC warning when WIDE_EMACS_INT.
1899
1900 * indent.c (sane_tab_width): New function.
1901 (current_column, scan_for_column, Findent_to, position_indentation)
1902 (compute_motion): Use it. This is just for clarity.
1903 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
1904
1905 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
1906
1907 * lisp.h (lint_assume): New macro.
1908 * composite.c (composition_gstring_put_cache):
1909 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
1910
1911 * editfns.c, insdel.c:
1912 Omit unnecessary forward decls, to simplify future changes.
1913
1914 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
1915
1916 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
1917
1918 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
1919 Use much-faster test for byte-length change.
1920 Don't assume string byte-length fits in 'int'.
1921 Check that character arg fits in 'int'.
1922 (mapcar1): Declare byte as byte, for clarity.
1923
1924 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
1925
1926 * fns.c (concat): Catch string overflow earlier.
1927 Do not rely on integer wraparound.
1928
1929 * dispextern.h (struct it.overlay_strings_charpos)
1930 (struct it.selective): Now EMACS_INT, not int.
1931 * xdisp.c (forward_to_next_line_start)
1932 (back_to_previous_visible_line_start)
1933 (reseat_at_next_visible_line_start, next_element_from_buffer):
1934 Don't arbitrarily truncate the value of 'selective' to int.
1935
1936 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
1937
1938 * composite.c: Don't truncate sizes to 'int'.
1939 (composition_gstring_p, composition_reseat_it)
1940 (composition_adjust_point): Use EMACS_INT, not int.
1941 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
1942 not EMACS_UINT, for indexes.
1943
1944 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
1945
1946 * buffer.c: Include <verify.h>.
1947 (struct sortvec.priority, struct sortstr.priority):
1948 Now EMACS_INT, not int.
1949 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
1950 (struct sortstr.size, record_overlay_string)
1951 (struct sortstrlist.size, struct sortlist.used):
1952 Don't truncate size to int.
1953 (record_overlay_string): Check for size-calculation overflow.
1954 (init_buffer_once): Check at compile-time, not run-time.
1955
19562011-06-22 Jim Meyering <meyering@redhat.com>
1957
1958 Don't leak an XBM-image-sized buffer
1959 * image.c (xbm_load): Free the image buffer after using it.
1960
19612011-06-21 Paul Eggert <eggert@cs.ucla.edu>
1962
1963 Port to Sun C.
1964 * composite.c (find_automatic_composition): Omit needless 'return 0;'
1965 that Sun C diagnosed.
1966 * fns.c (secure_hash): Fix pointer signedness issue.
1967 * intervals.c (static_offset_intervals): New function.
1968 (offset_intervals): Use it.
1969
19702011-06-21 Leo Liu <sdl.web@gmail.com>
1971
1972 * deps.mk (fns.o):
1973 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
1974 sha512.h.
1975
1976 * fns.c (secure_hash): Rename from crypto_hash_function and change
1977 the first arg to accept symbols.
1978 (Fsecure_hash): New primitive.
1979 (syms_of_fns): New symbols.
1980
19812011-06-20 Deniz Dogan <deniz@dogan.se>
1982
1983 * process.c (Fset_process_buffer): Clarify return value in
1984 docstring.
1985
19862011-06-18 Chong Yidong <cyd@stupidchicken.com>
1987
1988 * dispnew.c (add_window_display_history): Use BVAR.
1989
1990 * xdisp.c (debug_method_add): Use BVAR.
1991 (check_window_end, dump_glyph_matrix, dump_glyph)
1992 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
1993
1994 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
1995 Likewise.
1996
1997 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
1998 check till after the cache is created in init_frame_faces.
1999
20002011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
2001
2002 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
2003
20042011-06-16 Paul Eggert <eggert@cs.ucla.edu>
2005
2006 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
2007 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
2008 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
2009
2010 Improve buffer-overflow checking (Bug#8873).
2011 * fileio.c (Finsert_file_contents):
2012 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
2013 Remove the old (too-loose) buffer overflow checks.
2014 They weren't needed, since make_gap checks for buffer overflow.
2015 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
2016 The old code merely checked for Emacs fixnum overflow, and relied
2017 on undefined (wraparound) behavior. The new code avoids undefined
2018 behavior, and also checks for ptrdiff_t and/or size_t overflow.
2019
2020 * editfns.c (Finsert_char): Don't dump core with very negative counts.
2021 Tune. Don't use wider integers than needed. Don't use alloca.
2022 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
2023
2024 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
2025
2026 * insdel.c, lisp.h (buffer_overflow): New function.
2027 (insert_from_buffer_1, replace_range, replace_range_2):
2028 * insdel.c (make_gap_larger):
2029 * editfns.c (Finsert_char):
2030 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
2031
2032 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
2033
20342011-06-15 Paul Eggert <eggert@cs.ucla.edu>
2035
2036 Integer overflow and signedness fixes (Bug#8873).
2037
2038 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
2039 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
2040
2041 * fileio.c: Don't assume EMACS_INT fits in off_t.
2042 (emacs_lseek): New static function.
2043 (Finsert_file_contents, Fwrite_region): Use it.
2044 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
2045
2046 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
2047
2048 * fns.c: Don't overflow int when computing a list length.
2049 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
2050 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
2051 truncation on 64-bit hosts. Check for QUIT every
2052 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
2053 faster and is responsive enough.
2054 (Flength): Report an error instead of overflowing an integer.
2055 (Fsafe_length): Return a float if the value is not representable
2056 as a fixnum. This shouldn't happen except in contrived situations.
2057 (Fnthcdr, Fsort): Don't assume list length fits in int.
2058 (Fcopy_sequence): Don't assume vector length fits in int.
2059
2060 * alloc.c: Check that resized vectors' lengths fit in fixnums.
2061 (header_size, word_size): New constants.
2062 (allocate_vectorlike): Don't check size overflow here.
2063 (allocate_vector): Check it here instead, since this is the only
2064 caller of allocate_vectorlike that could cause overflow.
2065 Check that the new vector's length is representable as a fixnum.
2066
2067 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
2068 The previous code was bogus. For example, next_almost_prime (32)
2069 returned 39, which is undesirable as it is a multiple of 3; and
2070 next_almost_prime (24) returned 25, which is a multiple of 5 so
2071 why was the code bothering to check for multiples of 7?
2072
2073 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
2074
2075 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
2076
2077 Variadic C functions now count arguments with ptrdiff_t.
2078 This partly undoes my 2011-03-30 change, which replaced int with size_t.
2079 Back then I didn't know that the Emacs coding style prefers signed int.
2080 Also, in the meantime I found a few more instances where arguments
2081 were being counted with int, which may truncate counts on 64-bit
2082 machines, or EMACS_INT, which may be unnecessarily wide.
2083 * lisp.h (struct Lisp_Subr.function.aMANY)
2084 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
2085 Arg counts are now ptrdiff_t, not size_t.
2086 All variadic functions and their callers changed accordingly.
2087 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
2088 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
2089 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
2090 * callint.c (Fcall_interactively): Check arg count for overflow,
2091 to avoid potential buffer overrun. Use signed char, not 'int',
2092 for 'varies' array, so that we needn't bother to check its size
2093 calculation for overflow.
2094 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
2095 * eval.c (apply_lambda):
2096 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
2097 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
2098 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
2099
2100 * callint.c (Fcall_interactively): Don't use index var as event count.
2101
2102 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
2103 * mem-limits.h (SIZE): Remove; no longer used.
2104
2105 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
2106
2107 Remove unnecessary casts.
2108 * xterm.c (x_term_init):
2109 * xfns.c (x_set_border_pixel):
2110 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
2111 These aren't needed now that we assume ANSI C.
2112
2113 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
2114 It's more likely to cause problems (due to unsigned overflow)
2115 than to cure them.
2116
2117 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
2118
2119 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
2120
2121 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
2122
2123 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
2124
2125 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
2126
2127 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
2128
2129 GLYPH_CODE_FACE returns EMACS_INT, not int.
2130 * dispextern.h (merge_faces):
2131 * xfaces.c (merge_faces):
2132 * xdisp.c (get_next_display_element, next_element_from_display_vector):
2133 Don't assume EMACS_INT fits in int.
2134
2135 * character.h (CHAR_VALID_P): Remove unused parameter.
2136 * fontset.c, lisp.h, xdisp.c: All uses changed.
2137
2138 * editfns.c (Ftranslate_region_internal): Omit redundant test.
2139
2140 * fns.c (concat): Minor tuning based on overflow analysis.
2141 This doesn't fix any bugs. Use int to hold character, instead
2142 of constantly refetching from Emacs object. Use XFASTINT, not
2143 XINT, for value known to be a character. Don't bother comparing
2144 a single byte to 0400, as it's always less.
2145
2146 * floatfns.c (Fexpt):
2147 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
2148
2149 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
2150 for characters.
2151
2152 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
2153
2154 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
2155 Without this fix, on a 64-bit host (aset S 0 4294967386) would
2156 incorrectly succeed when S was a string, because 4294967386 was
2157 truncated before it was used.
2158
2159 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
2160 Otherwise, an out-of-range integer could cause undefined behavior
2161 on a 64-bit host.
2162
2163 * composite.c: Use int, not EMACS_INT, for characters.
2164 (fill_gstring_body, composition_compute_stop_pos): Use int, not
2165 EMACS_INT, for values that are known to be in character range.
2166 This doesn't fix any bugs but is the usual style inside Emacs and
2167 may generate better code on 32-bit machines.
2168
2169 Make sure a 64-bit char is never passed to ENCODE_CHAR.
2170 This is for reasons similar to the recent CHAR_STRING fix.
2171 * charset.c (Fencode_char): Check that character arg is actually
2172 a character. Pass an int to ENCODE_CHAR.
2173 * charset.h (ENCODE_CHAR): Verify that the character argument is no
2174 wider than 'int', as a compile-time check to prevent future regressions
2175 in this area.
2176
2177 * character.c (char_string): Remove unnecessary casts.
2178
2179 Make sure a 64-bit char is never passed to CHAR_STRING.
2180 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
2181 by silently ignoring the top 32 bits, allowing some values
2182 that were far too large to be valid characters.
2183 * character.h: Include <verify.h>.
2184 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
2185 arguments are no wider than unsigned, as a compile-time check
2186 to prevent future regressions in this area.
2187 * data.c (Faset):
2188 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
2189 (Fsubst_char_in_region):
2190 * fns.c (concat):
2191 * xdisp.c (decode_mode_spec_coding):
2192 Adjust to CHAR_STRING's new requirement.
2193 * editfns.c (Finsert_char, Fsubst_char_in_region):
2194 * fns.c (concat): Check that character args are actually
2195 characters. Without this test, these functions did the wrong
2196 thing with wildly out-of-range values on 64-bit hosts.
2197
2198 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
2199 These casts should not be needed on 32-bit hosts, either.
2200 * keyboard.c (read_char):
2201 * lread.c (Fload): Remove casts to unsigned.
2202
2203 * lisp.h (UNSIGNED_CMP): New macro.
2204 This fixes comparison bugs on 64-bit hosts.
2205 (ASCII_CHAR_P): Use it.
2206 * casefiddle.c (casify_object):
2207 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
2208 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
2209 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
2210 * dispextern.h (FACE_FROM_ID):
2211 * keyboard.c (read_char): Use UNSIGNED_CMP.
2212
2213 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
2214 not to EMACS_INT, to avoid GCC warning.
2215
2216 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
2217
2218 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
2219 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
2220 isn't needed on 32-bit machines.
2221
2222 * buffer.c (Fgenerate_new_buffer_name):
2223 Use EMACS_INT for count, not int.
2224 (advance_to_char_boundary): Return EMACS_INT, not int.
2225
2226 * data.c (Qcompiled_function): Now static.
2227
2228 * window.c (window_body_lines): Now static.
2229
2230 * image.c (gif_load): Rename local to avoid shadowing.
2231
2232 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
2233 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
2234 * alloc.c (make_save_value): Integer argument is now of type
2235 ptrdiff_t, not int.
2236 (mark_object): Use ptrdiff_t, not int.
2237 * lisp.h (pD): New macro.
2238 * print.c (print_object): Use it.
2239
2240 * alloc.c: Use EMACS_INT, not int, to count objects.
2241 (total_conses, total_markers, total_symbols, total_vector_size)
2242 (total_free_conses, total_free_markers, total_free_symbols)
2243 (total_free_floats, total_floats, total_free_intervals)
2244 (total_intervals, total_strings, total_free_strings):
2245 Now EMACS_INT, not int. All uses changed.
2246 (Fgarbage_collect): Compute overall total using a double, so that
2247 integer overflow is less likely to be a problem. Check for overflow
2248 when converting back to an integer.
2249 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
2250 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
2251 These were 'int' variables that could overflow on 64-bit hosts;
2252 they were never used, so remove them instead of repairing them.
2253 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
2254 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
2255 Previously, this ceilinged at INT_MAX, but that doesn't work on
2256 64-bit machines.
2257 (allocate_pseudovector): Don't use EMACS_INT when int would do.
2258
2259 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
2260 (allocate_vectorlike): Check for ptrdiff_t overflow.
2261 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
2262 when a (possibly-narrower) signed value would do just as well.
2263 We prefer using signed arithmetic, to avoid comparison confusion.
2264
2265 * alloc.c: Catch some string size overflows that we were missing.
2266 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
2267 for convenience in STRING_BYTES_MAX.
2268 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
2269 The definition here is exact; the one in lisp.h was approximate.
2270 (allocate_string_data): Check for string overflow. This catches
2271 some instances we weren't catching before. Also, it catches
2272 size_t overflow on (unusual) hosts where SIZE_MAX <= min
2273 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
2274 and ptrdiff_t and EMACS_INT are both 64 bits.
2275
2276 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
2277 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
2278 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
2279
2280 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
2281
2282 * alloc.c (Fmake_string): Check for out-of-range init.
2283
22842011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
2285
2286 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
2287
22882011-06-14 Jan Djärv <jan.h.d@swipnet.se>
2289
2290 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
2291 xg_get_default_scrollbar_width.
2292
2293 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
2294 (int_gtk_range_get_value): Move to the scroll bar part of the file.

2307
2308 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.

2311
23122011-06-12 Martin Rudalics <rudalics@gmx.at>
2313
2314 * frame.c (make_frame): Call other_buffer_safely instead of
2315 other_buffer.
2316
2317 * window.c (temp_output_buffer_show): Call display_buffer with
2318 second argument Vtemp_buffer_show_specifiers and reset latter
2319 immediately after the call.

2321 (auto_window_vscroll_p, next_screen_context_lines)
2322 (Vscroll_preserve_screen_position): Remove leading asterisks from
2323 doc-strings.

2786 is separated from the issue of spare memory.
2787

2846 display string.
2847 (bidi_paragraph_init, bidi_resolve_explicit_1)
2848 (bidi_level_of_next_char): Call bidi_fetch_char and

2855 instead of using explicit *_CHAR codes.
2856 (bidi_resolve_explicit, bidi_resolve_weak):

2867 were just reseat()'ed to a new position.
2868
2869 * xdisp.c (set_cursor_from_row): Set start and stop points
2870 according to the row's direction when priming the loop that looks

2873 (display_prop_intangible_p): Reimplement to call
2874 handle_display_spec instead of single_display_spec_intangible_p.
2875 Accept 3 additional arguments needed by handle_display_spec.
2876 This fixes incorrect cursor motion across display property with complex
2877 values: lists, `(when COND...)' forms, etc.

2879 lists with the argument STRING its top-level element.
2880 (display_prop_string_p): Fix the condition for processing a
2881 property that is a list to be consistent with handle_display_spec.

2883 last portion of handle_display_prop.
2884 (compute_display_string_pos): Accept additional argument

2886 value of a `display' property is a "replacing spec".
2887 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
2888 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

2916 All callers changed. (Bug#8762)
2917
2918 * gnutls.c: Use Emacs's memory allocators.
2919 Without this change, the gnutls library would invoke malloc etc.
2920 directly, which causes problems on non-SYNC_INPUT hosts, and which
2921 runs afoul of improving memory_full behavior. (Bug#8761)
2922 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
2923 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
2924 xfree instead of the default malloc, realloc, free.
2925 (Fgnutls_boot): No need to check for memory allocation failure,
2926 since xmalloc does that for us.
2927

2948 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
2949 for hashes and hash indexes, instead of 'unsigned' and 'int'.
2950 * alloc.c (allocate_vectorlike):
2951 Check for overflow in vector size calculations.

2955 need to be updated by these changes.
2956 * fns.c (make_hash_table, maybe_resize_hash_table):
2957 Check for integer overflow with large hash tables.
2958 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
2959 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
2960 (SXHASH_REDUCE): New macro.
2961 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
2962 Use it instead of discarding useful hash info with large hash values.
2963 (sxhash_float): New function.
2964 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
2965 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
2966 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
2967 Rewrite to use FIXNUM_BITS, as this simplifies things.
2968 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
2969 Adjust signatures to match updated version of code.
2970 (consing_since_gc): Now EMACS_INT, since a single hash table can
2971 use more than INT_MAX bytes.
2972
29732011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
2974
2975 Make it possible to build with GCC-4.6+ -O2 -flto.

2987 Update dependencies.
2988
29892011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
2990
2991 * data.c (init_data): Remove code for UTS, this system is not
2992 supported anymore.
2993
29942011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
2995
2996 Don't force ./temacs to start in terminal mode.
2997
2998 * frame.c (make_initial_frame): Initialize faces in all cases, not
2999 only when CANNOT_DUMP is defined.

3001
30022011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3003
3004 * dispnew.c (add_window_display_history): Use const for the string
3005 pointer. Remove declaration, not needed.
3006
30072011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3008
3009 Use 'inline', not 'INLINE'.
3010 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
3011 * alloc.c, fontset.c (INLINE): Remove.
3012 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
3013 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
3014 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
3015 * gmalloc.c (register_heapinfo): Use inline unconditionally.
3016 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
3017
30182011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3019
3020 Make it possible to run ./temacs.
3021
3022 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
3023 syms_of_callproc does the same thing. Remove test for
3024 "initialized", do it in the caller.
3025 * emacs.c (main): Avoid calling set_initial_environment when dumping.
3026
30272011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
3028
3029 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
3030 (read_minibuf): Use get_minibuffer.
3031 (syms_of_minibuf): Use DEFSYM.
3032 (Qmetadata): New var.
3033 * data.c (Qbuffer): Don't make it static.
3034 (syms_of_data): Use DEFSYM.
3035
30362011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3037
3038 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
3039 (CCL_CODE_MIN): New macro.
3040
30412011-05-30 Paul Eggert <eggert@cs.ucla.edu>
3042
3043 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
3044
3045 * eval.c (Qdebug): Now static.
3046 * lisp.h (Qdebug): Remove decl. This reverts a part of the
3047 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
3048 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
3049
30502011-05-29 Chong Yidong <cyd@stupidchicken.com>
3051
3052 * image.c: Various fixes to ImageMagick code comments.
3053 (Fimagemagick_types): Doc fix.
3054
30552011-05-29 Paul Eggert <eggert@cs.ucla.edu>
3056
3057 Minor fixes prompted by GCC 4.6.0 warnings.
3058
3059 * xselect.c (converted_selections, conversion_fail_tag): Now static.
3060
3061 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
3062 (x_clipboard_manager_save_all): Move extern decl to ...
3063 * xterm.h: ... here, so that it can be checked for consistency.
3064
30652011-05-29 Chong Yidong <cyd@stupidchicken.com>
3066
3067 * xselect.c (x_clipboard_manager_save_frame)
3068 (x_clipboard_manager_save_all): New functions.
3069 (Fx_clipboard_manager_save): Lisp function deleted.
3070
3071 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
3072 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
3073
3074 * xterm.h: Update prototype.
3075
30762011-05-28 William Xu <william.xwl@gmail.com>
3077
3078 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
3079 exiting (Bug#8239).
3080
30812011-05-28 Jim Meyering <meyering@redhat.com>
3082
3083 Avoid a sign-extension bug in crypto_hash_function.
3084 * fns.c (to_uchar): Define.
3085 (crypto_hash_function): Use it to convert some newly-signed
3086 variables to unsigned, to avoid sign-extension bugs. For example,
3087 without this change, (md5 "truc") would evaluate to
3088 45723a2aff78ff4fff7fff1114760e62 rather than the expected
3089 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
3090 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
3091
30922011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3093
3094 Integer overflow fixes.
3095
3096 * dbusbind.c: Serial number integer overflow fixes.
3097 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
3098 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
3099 to hold a serial number that is too large for a fixnum.
3100 (Fdbus_method_return_internal, Fdbus_method_error_internal):
3101 Check for serial numbers out of range. Decode any serial number
3102 that was so large that it became a float. (Bug#8722)
3103
3104 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
3105 (Fdbus_call_method, Fdbus_call_method_asynchronously):
3106 Use XFASTINT rather than XUINT when numbers are nonnegative.
3107 (xd_append_arg, Fdbus_method_return_internal):
3108 (Fdbus_method_error_internal): Likewise. Also, for unsigned
3109 arguments, check that Lisp number is nonnegative, rather than
3110 silently wrapping negative numbers around. (Bug#8722)
3111 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
3112 (Bug#8722)
3113
3114 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
3115
3116 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
3117
3118 ccl: add integer overflow checks
3119 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
3120 (IN_INT_RANGE): New macros.
3121 (ccl_driver): Use them to check for integer overflow when
3122 decoding a CCL program. Many of the new checks are whether XINT (x)
3123 fits in int; it doesn't always, on 64-bit hosts. The new version
3124 doesn't catch all possible integer overflows, but it's an
3125 improvement. (Bug#8719)
3126
3127 * alloc.c (make_event_array): Use XINT, not XUINT.
3128 There's no need for unsigned here.
3129
3130 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
3131 This follows up to the 2011-05-06 change that substituted uintptr_t
3132 for EMACS_INT. This case wasn't caught back then.
3133
3134 Rework Fformat to avoid integer overflow issues.
3135 * editfns.c: Include <float.h> unconditionally, as it's everywhere
3136 now (part of C89). Include <verify.h>.
3137 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
3138 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
3139 (Fformat): Avoid the prepass trying to compute sizes; it was only
3140 approximate and thus did not catch overflow reliably. Instead, walk
3141 through the format just once, formatting and computing sizes as we go,
3142 checking for integer overflow at every step, and allocating a larger
3143 buffer as needed. Keep track separately whether the format is
3144 multibyte. Keep only the most-recently calculated precision, rather
3145 than them all. Record whether each argument has been converted to
3146 string. Use EMACS_INT, not int, for byte and char and arg counts.
3147 Support field widths and precisions larger than INT_MAX. Avoid
3148 sprintf's undefined behavior with conversion specifications such as %#d
3149 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
3150 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
3151 formatting out-of-range floating point numbers with int
3152 formats. (Bug#8668)
3153
3154 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
3155
3156 * data.c: Avoid integer truncation in expressions involving floats.
3157 * data.c: Include <intprops.h>.
3158 (arith_driver): When there's an integer overflow in an expression
3159 involving floating point, convert the integers to floating point
3160 so that the resulting value does not suffer from catastrophic
3161 integer truncation. For example, on a 64-bit host (* 4
3162 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
3163 Do not rely on undefined behavior after integer overflow.
3164
3165 merge count_size_as_multibyte, parse_str_to_multibyte
3166 * character.c, character.h (count_size_as_multibyte):
3167 Rename from parse_str_to_multibyte; all uses changed.
3168 Check for integer overflow.
3169 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
3170 since it's now a duplicate of the other. This is more of
3171 a character than a buffer op, so better that it's in character.c.
3172 * fns.c, print.c: Adjust to above changes.
3173
31742011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
3175
3176 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
3177
31782011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3179
3180 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3181 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
3182 (x_clipboard_manager_save): Now static.
3183 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
3184
3185 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3186 (crypto_hash_function): Now static.
3187 Fix pointer signedness problems. Avoid unnecessary initializations.
3188
31892011-05-27 Chong Yidong <cyd@stupidchicken.com>
3190
3191 * termhooks.h (Vselection_alist): Make it terminal-local.
3192
3193 * terminal.c (create_terminal): Initialize it.
3194
3195 * xselect.c: Support for clipboard managers.
3196 (Vselection_alist): Move to termhooks.h as terminal-local var.
3197 (LOCAL_SELECTION): New macro.
3198 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
3199 (symbol_to_x_atom): Remove gratuitous arg.
3200 (x_handle_selection_request, lisp_data_to_selection_data)
3201 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
3202 (x_own_selection, x_get_local_selection, x_convert_selection):
3203 New arg, specifying work frame. Use terminal-local Vselection_alist.
3204 (some_frame_on_display): Delete unused function.
3205 (Fx_own_selection_internal, Fx_get_selection_internal)
3206 (Fx_disown_selection_internal, Fx_selection_owner_p)
3207 (Fx_selection_exists_p): New optional frame arg.
3208 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
3209 (x_handle_selection_clear): Don't treat other terminals with the
3210 same keyboard specially. Use the terminal-local Vselection_alist.
3211 (x_clear_frame_selections): Use Frun_hook_with_args.
3212
3213 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
3214
3215 * xterm.h: Add support for those atoms.
3216
32172011-05-26 Chong Yidong <cyd@stupidchicken.com>
3218
3219 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
3220 (converted_selections, conversion_fail_tag): New global variables.
3221 (x_selection_request_lisp_error): Free the above.
3222 (x_get_local_selection): Remove unnecessary code.
3223 (x_reply_selection_request): Args changed; handle arbitrary array
3224 of converted selections stored in converted_selections.
3225 Separate the XChangeProperty and SelectionNotify steps.
3226 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
3227 (x_convert_selection): New function.
3228 (x_handle_selection_event): Simplify.
3229 (x_get_foreign_selection): Don't ignore incoming requests while
3230 waiting for an answer; this will fail when we implement
3231 SAVE_TARGETS, and seems unnecessary anyway.
3232 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
3233 (Vx_sent_selection_functions): Doc fix.
3234
32352011-05-26 Leo Liu <sdl.web@gmail.com>
3236
3237 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
3238
32392011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3240
3241 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
3242
3243 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
3244 for fringe update if it has periodic bitmap.
3245 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
3246 and fringe_bitmap_periodic_p.
3247
3248 * fringe.c (get_fringe_bitmap_data): New function.
3249 (draw_fringe_bitmap_1, update_window_fringes): Use it.
3250 (update_window_fringes): Record periodicity of fringe bitmap in glyph
3251 row. Mark glyph row for fringe update if periodicity changed.
3252
3253 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
3254 for fringe update unless it has periodic bitmap.
3255
32562011-05-25 Kenichi Handa <handa@m17n.org>
3257
3258 * xdisp.c (get_next_display_element): Set correct it->face_id for
3259 a static composition.
3260
32612011-05-24 Leo Liu <sdl.web@gmail.com>
3262
3263 * deps.mk (fns.o):
3264 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
3265
3266 * fns.c (crypto_hash_function, Fsha1): New function.
3267 (Fmd5): Use crypto_hash_function.
3268 (syms_of_fns): Add Ssha1.
3269
32702011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3271
3272 * gnutls.c: Remove unused macros.
3273 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
3274 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
3275 Remove macros that are defined and never used.
3276 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
3277
32782011-05-22 Chong Yidong <cyd@stupidchicken.com>
3279
3280 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
3281 (Fx_get_selection_internal): Minor cleanup.
3282 (Fx_own_selection_internal): Rename arguments for consistency with
3283 select.el.
3284
32852011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3286
3287 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
3288
32892011-05-22 Chong Yidong <cyd@stupidchicken.com>
3290
3291 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
3292
32932011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3294
3295 * dispnew.c (scrolling_window): Don't exclude the case that the
3296 last enabled row in the desired matrix touches the bottom boundary.
3297
32982011-05-21 Glenn Morris <rgm@gnu.org>
3299
3300 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
3301 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
3302 and add some more files.
3303
33042011-05-20 Eli Zaretskii <eliz@gnu.org>
3305
3306 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
3307 report_file_error introduced by the change from 2011-05-07.
3308
33092011-05-20 Paul Eggert <eggert@cs.ucla.edu>
3310
3311 * systime.h (Time): Define only if emacs is defined.
3312 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
3313 where the include path doesn't have X11/X.h by default. See
3314 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
3315
33162011-05-20 Kenichi Handa <handa@m17n.org>
3317
3318 * composite.c (find_automatic_composition): Fix previous change.
3319
33202011-05-20 Glenn Morris <rgm@gnu.org>
3321
3322 * lisp.mk: New file, split from Makefile.in.
3323 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
3324 (shortlisp): Remove.
3325 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
3326
33272011-05-19 Glenn Morris <rgm@gnu.org>
3328
3329 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
3330 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
3331 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
3332 (lisp): Set the order to that of loadup.el.
3333 (shortlisp): Make it a copy of $lisp.
3334 (SOME_MACHINE_LISP): Remove.
3335 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
3336 Use just $shortlisp, not $SOME_MACHINE_LISP too.
3337
33382011-05-18 Kenichi Handa <handa@m17n.org>
3339
3340 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
3341 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
3342 (find_automatic_composition): Mostly rewrite for efficiency.
3343
33442011-05-18 Juanma Barranquero <lekktu@gmail.com>
3345
3346 * makefile.w32-in: Update dependencies.
3347
33482011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
3349
3350 * menu.c: Include limits.h (fixes the MS-Windows build broken by
3351 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
3352
33532011-05-18 Paul Eggert <eggert@cs.ucla.edu>
3354
3355 Fix some integer overflow issues, such as string length overflow.
3356
3357 * insdel.c (count_size_as_multibyte): Check for string overflow.
3358
3359 * character.c (lisp_string_width): Check for string overflow.
3360 Use EMACS_INT, not int, for string indexes and lengths; in
3361 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
3362 the resulting string length overflows an EMACS_INT; instead,
3363 report a string overflow if no precision given. When checking for
3364 precision exhaustion, use a check that cannot possibly have
3365 integer overflow. (Bug#8675)
3366 * character.h (lisp_string_width): Adjust to new signature.
3367
3368 * alloc.c (string_overflow): New function.
3369 (Fmake_string): Use it. This doesn't change behavior, but saves
3370 a few bytes and will simplify future changes.
3371 * character.c (string_escape_byte8): Likewise.
3372 * lisp.h (string_overflow): New decl.
3373
3374 Fixups, following up to the user-interface timestamp change.
3375 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
3376 for UI timestamps, instead of unsigned long.
3377 * msdos.c (mouse_get_pos): Likewise.
3378 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
3379 * w32gui.h (Time): Define by including "systime.h" rather than by
3380 declaring it ourselves. (Bug#8664)
3381
3382 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
3383 * image.c (clear_image_cache): Likewise.
3384
3385 * term.c (term_mouse_position): Don't assume time_t wraparound.
3386
3387 Be more systematic about user-interface timestamps.
3388 Before, the code sometimes used 'Time', sometimes 'unsigned long',
3389 and sometimes 'EMACS_UINT', to represent these timestamps.
3390 This change causes it to use 'Time' uniformly, as that's what X uses.
3391 This makes the code easier to follow, and makes it easier to catch
3392 integer overflow bugs such as Bug#8664.
3393 * frame.c (Fmouse_position, Fmouse_pixel_position):
3394 Use Time, not unsigned long, for user-interface timestamps.
3395 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
3396 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
3397 * keyboard.h (last_event_timestamp): Likewise.
3398 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
3399 * menu.h (xmenu_show): Likewise.
3400 * term.c (term_mouse_position): Likewise.
3401 * termhooks.h (struct input_event.timestamp): Likewise.
3402 (struct terminal.mouse_position_hook): Likewise.
3403 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
3404 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
3405 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
3406 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
3407 what it was before.
3408 * menu.h, termhooks.h: Include "systime.h", for Time.
3409
3410 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
3411 Don't assume that the difference between two unsigned long values
3412 can fit into an integer. At this point, we know button_down_time
3413 <= event->timestamp, so the difference must be nonnegative, so
3414 there's no need to cast the result if double-click-time is
3415 nonnegative, as it should be; check that it's nonnegative, just in
3416 case. This bug is triggered when events are more than 2**31 ms
3417 apart (about 25 days). (Bug#8664)
3418
3419 * xselect.c (last_event_timestamp): Remove duplicate decl.
3420 (x_own_selection): Remove needless cast to unsigned long.
3421
3422 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
3423 that always fit in int. Use a sentinel instead of a counter, to
3424 avoid a temp and to allay GCC's concerns about possible int overflow.
3425 * frame.h (struct frame): Use int for menu_bar_items_used
3426 instead of EMACS_INT, since it always fits in int.
3427
3428 * menu.c (grow_menu_items): Check for int overflow.
3429
3430 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
3431
3432 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
3433 Before, the code was not consistent. These values cannot exceed
3434 2**31 - 1 so there's no need to make them unsigned.
3435 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
3436 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
3437 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
3438 as modifiers.
3439 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
3440
3441 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
3442 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
3443 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
3444 presumably because the widths might not match.
3445
3446 * window.c (size_window): Avoid needless test at loop start.
3447
34482011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
3449
3450 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
3451
34522011-05-12 Drew Adams <drew.adams@oracle.com>
3453
3454 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
3455
34562011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3457
3458 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
3459 `width' to `bar_area_x' and `bar_area_width', respectively.
3460 (x_scroll_run): Take account of fringe background extension.
3461
3462 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
3463 Rename local vars `left' and `width' to `bar_area_x' and
3464 `bar_area_width', respectively.
3465 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
3466 background extension.
3467
34682011-05-10 Jim Meyering <meyering@redhat.com>
3469
3470 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
3471
34722011-05-10 Juanma Barranquero <lekktu@gmail.com>
3473
3474 * image.c (Finit_image_library): Return t for built-in image types,
3475 like pbm and xbm. (Bug#8640)
3476
34772011-05-09 Andreas Schwab <schwab@linux-m68k.org>
3478
3479 * w32menu.c (set_frame_menubar): Fix submenu allocation.
3480
34812011-05-07 Eli Zaretskii <eliz@gnu.org>
3482
3483 * w32console.c (Fset_screen_color): Doc fix.
3484 (Fget_screen_color): New function.
3485 (syms_of_ntterm): Defsubr it.
3486
3487 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
3488 unlink the temporary file if Fcall_process didn't create it in the
3489 first place.
3490 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
3491 child process will be redirected to a file specified with `:file'.
3492 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
3493 cue to call_process_cleanup not to close that handle.
3494
34952011-05-07 Ben Key <bkey76@gmail.com>
3496
3497 * makefile.w32-in: The bootstrap-temacs rule now makes use of
3498 one of two shell specific rules, either bootstrap-temacs-CMD or
3499 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
3500 to the previous implementation of the bootstrap-temacs rule.
3501 The bootstrap-temacs-CMD rule is similar to the previous
3502 implementation of the bootstrap-temacs rule except that it
3503 makes use of the ESC_CFLAGS variable instead of the CFLAGS
3504 variable.
3505
3506 These changes, along with some changes to nt/configure.bat,
3507 nt/gmake.defs, and nt/nmake.defs, are required to extend my
3508 earlier fix to add support for --cflags and --ldflags options
3509 that include quotes so that it works whether make uses cmd or
3510 sh as the shell.
3511
35122011-05-06 Michael Albinus <michael.albinus@gmx.de>
3513
3514 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
3515 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
3516 is a constant.
3517 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
3518 a string. Handle both cases.
3519 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
3520 (Fdbus_register_method): Use Qinvalid_function.
3521
35222011-05-06 Juanma Barranquero <lekktu@gmail.com>
3523
3524 * makefile.w32-in: Update dependencies.
3525 (LISP_H): Add inttypes.h and stdin.h.
3526 (PROCESS_H): Add unistd.h.
3527
35282011-05-06 Eli Zaretskii <eliz@gnu.org>
3529
3530 * lread.c: Include limits.h (fixes the MS-Windows build broken by
3531 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
3532
35332011-05-06 Paul Eggert <eggert@cs.ucla.edu>
3534
3535 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
3536
3537 * term.c (vfatal): Remove stray call to va_end.
3538 It's not needed and the C Standard doesn't allow it here anyway.
3539
3540 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
3541 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
3542
3543 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
3544 bytes.
3545
3546 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
3547
3548 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3549
3550 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
3551
3552 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
3553
3554 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
3555
3556 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
3557 * charset.c (Fdefine_charset_internal): Don't initialize
3558 charset.code_space[15]. The value was garbage, on hosts with
3559 32-bit int (Bug#8600).
3560
3561 * lread.c (read_integer): Be more consistent with string-to-number.
3562 Use string_to_number to do the actual conversion; this avoids
3563 rounding errors and fixes some other screwups. Without this fix,
3564 for example, #x1fffffffffffffff was misread as -2305843009213693952.
3565 (digit_to_number): Move earlier, for benefit of read_integer.
3566 Return -1 if the digit is out of range for the base, -2 if it is
3567 not a digit in any supported base. (Bug#8602)
3568
3569 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
3570
3571 * dispnew.c (scrolling_window): Return 1 if we scrolled,
3572 to match comment at start of function. This also removes a
3573 GCC warning about overflow in a 32+64-bit port.
3574
3575 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
3576
3577 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
3578 Reported by Stefan Monnier in
3579 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
3580 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3581 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
3582
3583 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
3584 (EMACS_UINTPTR): Likewise, with uintptr_t.
3585
3586 * lisp.h: Prefer 64-bit EMACS_INT if available.
3587 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
3588 on 32-bit hosts that have 64-bit int, so that they can access
3589 large files.
3590 However, temporarily disable this change unless the temporary
3591 symbol WIDE_EMACS_INT is defined.
3592
3593 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
3594
3595 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
3596 This removes an assumption that EMACS_INT and long are the same
3597 width as pointers. The assumption is true for Emacs porting targets
3598 now, but we want to make other targets possible.
3599 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
3600 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
3601 In the rest of the code, change types of integers that hold casted
3602 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
3603 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
3604 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
3605 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
3606 No need to cast type when ORing.
3607 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
3608 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
3609 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
3610 assume EMACS_INT is the same width as char *.
3611 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
3612 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
3613 Remove no-longer-needed casts.
3614 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
3615 (xg_tool_bar_help_callback, xg_make_tool_item):
3616 Use EMACS_INTPTR to hold an integer
3617 that will be cast to void *; this can avoid a GCC warning
3618 if EMACS_INT is not the same width as void *.
3619 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
3620 * xdisp.c (display_echo_area_1, resize_mini_window_1):
3621 (current_message_1, set_message_1):
3622 Use a local to convert to proper width without a cast.
3623 * xmenu.c (dialog_selection_callback): Likewise.
3624
3625 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
3626 Also, don't assume VALBITS / RAND_BITS is less than 5,
3627 and don't rely on undefined behavior when shifting a 1 left into
3628 the sign bit.
3629 * lisp.h (get_random): Change signature to match.
3630
3631 * lread.c (hash_string): Use size_t, not int, for hash computation.
3632 Normally we prefer signed values; but hashing is special, because
3633 it's better to use unsigned division on hash table sizes so that
3634 the remainder is nonnegative. Also, size_t is the natural width
3635 for hashing into memory. The previous code used 'int', which doesn't
3636 retain enough info to hash well into very large tables.
3637 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
3638
3639 * dbusbind.c: Don't possibly lose pointer info when converting.
3640 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3641 Use XPNTR rather than XHASH, so that the high-order bits of
3642 the pointer aren't lost when converting through void *.
3643
3644 * eval.c (Fautoload): Don't double-shift a pointer.
3645
3646 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
3647
36482011-05-06 Juanma Barranquero <lekktu@gmail.com>
3649
3650 * gnutls.c (DEF_GNUTLS_FN):
3651 * image.c (DEF_IMGLIB_FN): Make function pointers static.
3652
36532011-05-05 Andreas Schwab <schwab@linux-m68k.org>
3654
3655 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
3656 marker. (Bug#8610)
3657
36582011-05-05 Eli Zaretskii <eliz@gnu.org>
3659
3660 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
3661 New version that can reserve upto 2GB of heap space.
3662
36632011-05-05 Chong Yidong <cyd@stupidchicken.com>

3678
3679 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
3680 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
3681 Remove unused parameter `fildes'.
3682 * process.c (read_process_output, send_process): Don't pass it.
3683
36842011-05-04 Juanma Barranquero <lekktu@gmail.com>
3685
3686 Fix previous change: the library cache is defined in w32.c.
3687 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
3688 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
3689
36902011-05-04 Juanma Barranquero <lekktu@gmail.com>
3691
3692 Implement dynamic loading of GnuTLS on Windows.
3693

3695 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
3696 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
3697 Declare.
3698
3699 * gnutls.c (Qgnutls_dll): Define.
3700 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
3701 (gnutls_*): Declare function pointers.
3702 (init_gnutls_functions): New function to initialize function pointers.
3703 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
3704 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
3705 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
3706 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
3707 (emacs_gnutls_write, emacs_gnutls_read)
3708 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
3709 (Fgnutls_available_p): New function.
3710 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
3711 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
3712 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
3713
3714 * image.c: Include w32.h.
3715 (Vimage_type_cache): Delete.
3716 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
3717 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
3718 (w32_delayed_load): Move to w32.c.
3719
3720 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
3721
3722 * w32.c (QCloaded_from, Vlibrary_cache): Define.
3723 (w32_delayed_load): Move from image.c. When loading a library, record
3724 its filename in the :loaded-from property of the library id.
3725 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
3726 Initialize and staticpro them.
3727 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
3728
3729 * process.c: Include lisp.h before w32.h, not after.
3730 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
3731 instead of gnutls_record_check_pending.
3732
3733 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
3734

3736
3737 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
3738 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
3739 as passed in.
3740
37412011-05-03 Jan Djärv <jan.h.d@swipnet.se>

3759 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)

3763
3764 * callproc.c: Indentation fixup.

3772 * sysdep.c (interruptible_wait_for_termination): New function
3773 which is like wait_for_termination, but allows keyboard
3774 interruptions.
3775
3776 * callproc.c (Fcall_process): Add (:file "file") as an option for
3777 the STDOUT buffer.
3778 (Fcall_process_region): Ditto.

3781
3782 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
3783 rather than `XVECTOR (FOO)->size'.
3784
3785 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
3786 inttypes.h, as a gnulib replacement is used if it not available in
3787 system headers.
3788
37892011-04-21 Eli Zaretskii <eliz@gnu.org>
3790
3791 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
3792 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
3793 of MOST_POSITIVE_FIXNUM. (Bug#8528)
3794
3795 * coding.c (coding_alloc_by_realloc): Error out if destination
3796 will grow beyond MOST_POSITIVE_FIXNUM.
3797 (decode_coding_emacs_mule): Abort if there isn't enough place in
3798 charbuf for the composition carryover bytes. Reserve an extra
3799 space for up to 2 characters produced in a loop.
3800 (decode_coding_iso_2022): Abort if there isn't enough place in
3801 charbuf for the composition carryover bytes.
3802
38032011-04-21 Eli Zaretskii <eliz@gnu.org>
3804
3805 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
3806 aborting when %lld or %lll format is passed.
3807 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
3808 %llo or %llx format is passed. (Bug#8545)
3809
3810 * window.c (window_scroll_line_based): Use a marker instead of
3811 simple variables to record original value of point. (Bug#7952)
3812
3813 * doprnt.c (doprnt): Fix the case where a multibyte sequence
3814 produced by %s or %c overflows available buffer space. (Bug#8545)
3815
38162011-04-28 Paul Eggert <eggert@cs.ucla.edu>
3817
3818 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
3819 (SIZE_MAX): Move defn after all includes, as they might #define it.
3820
38212011-04-28 Juanma Barranquero <lekktu@gmail.com>
3822
3823 * w32.c (init_environment): Warn about defaulting HOME to C:\.
3824
38252011-04-28 Juanma Barranquero <lekktu@gmail.com>
3826
3827 * keyboard.c (Qdelayed_warnings_hook): Define.
3828 (command_loop_1): Run `delayed-warnings-hook'
3829 if Vdelayed_warnings_list is non-nil.
3830 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
3831 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
3832
38332011-04-28 Eli Zaretskii <eliz@gnu.org>
3834
3835 * doprnt.c (doprnt): Don't return value smaller than the buffer
3836 size if the message was truncated. (Bug#8545).
3837
38382011-04-28 Juanma Barranquero <lekktu@gmail.com>
3839
3840 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
3841 (Fx_window_property): #if-0 the whole functions, not just the bodies.
3842
38432011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3844
3845 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
3846
38472011-04-27 Juanma Barranquero <lekktu@gmail.com>
3848
3849 * makefile.w32-in: Update dependencies.
3850
38512011-04-27 Eli Zaretskii <eliz@gnu.org>
3852
3853 Improve `doprnt' and its usage. (Bug#8545)
3854 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
3855 `format_end'. Remove support for %l as a conversion specifier.
3856 Don't use xrealloc. Improve diagnostics when the %l size modifier
3857 is used. Update the commentary.
3858
3859 * eval.c (verror): Simplify calculation of size_t.
3860
3861 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
3862 messages.
3863
38642011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
3865
3866 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
3867 change.
3868
38692011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3870
3871 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
3872 This makes this file independent of the recent pseudovector change.
3873
38742011-04-26 Paul Eggert <eggert@cs.ucla.edu>
3875
3876 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
3877
3878 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
3879 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
3880 Remove unused local.
3881 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
3882
3883 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
3884 GCC 4.6.0 optimizes based on type-based alias analysis.
3885 For example, if b is of type struct buffer * and v of type struct
3886 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
3887 != &v->size, and therefore "v->size = 1; b->size = 2; return
3888 v->size;" must therefore return 1. This assumption is incorrect
3889 for Emacs, since it type-puns struct Lisp_Vector * with many other
3890 types. To fix this problem, this patch adds a new type struct
3891 vectorlike_header that documents the constraints on layout of vectors
3892 and pseudovectors, and helps optimizing compilers not get fooled
3893 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
3894 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
3895 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
3896 the size member.
3897 (XSETPVECTYPE): Rewrite in terms of new macro.
3898 (XSETPVECTYPESIZE): New macro, specifying both type and size.
3899 This is a bit clearer, and further avoids the possibility of
3900 undesirable aliasing.
3901 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
3902 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
3903 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
3904 since Lisp_Subr is a special case (no "next" field).
3905 (ASIZE): Now uses header.size rather than size.
3906 All previous uses of XVECTOR (foo)->size replaced to use this macro,
3907 to avoid the hassle of writing XVECTOR (foo)->header.size.
3908 (struct vectorlike_header): New type.
3909 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
3910 object, to help avoid aliasing.
3911 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
3912 (SUBRP): Likewise, since Lisp_Subr is a special case.
3913 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
3914 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
3915 (struct Lisp_Hash_Table): Combine first two members into a single
3916 struct vectorlike_header member. All uses of "size" and "next" members
3917 changed to be "header.size" and "header.next".
3918 * buffer.h (struct buffer): Likewise.
3919 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
3920 * frame.h (struct frame): Likewise.
3921 * process.h (struct Lisp_Process): Likewise.
3922 * termhooks.h (struct terminal): Likewise.
3923 * window.c (struct save_window_data, struct saved_window): Likewise.
3924 * window.h (struct window): Likewise.
3925 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
3926 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
3927 * buffer.c (init_buffer_once): Likewise.
3928 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
3929 special case.
3930 * process.c (Fformat_network_address): Use local var for size,
3931 for brevity.
3932
3933 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
3934
3935 Make the Lisp reader and string-to-float more consistent (Bug#8525)
3936 * data.c (atof): Remove decl; no longer used or needed.
3937 (digit_to_number): Move to lread.c.
3938 (Fstring_to_number): Use new string_to_number function, to be
3939 consistent with how the Lisp reader treats infinities and NaNs.
3940 Do not assume that floating-point numbers represent EMACS_INT
3941 without losing information; this is not true on most 64-bit hosts.
3942 Avoid double-rounding errors, by insisting on integers when
3943 parsing non-base-10 numbers, as the documentation specifies.
3944 * lisp.h (string_to_number): New decl, replacing ...
3945 (isfloat_string): Remove.
3946 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
3947 (read1): Do not accept +. and -. as integers; this
3948 appears to have been a coding error. Similarly, do not accept
3949 strings like +-1e0 as floating point numbers. Do not report
3950 overflow for integer overflows unless the base is not 10 which
3951 means we have no simple and reliable way to continue.
3952 Break out the floating-point parsing into a new
3953 function string_to_number, so that Fstring_to_number parses
3954 floating point numbers consistently with the Lisp reader.
3955 (digit_to_number): Move here from data.c. Make it static inline.
3956 (E_CHAR, EXP_INT): Remove, replacing with ...
3957 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
3958 (string_to_number): New function, replacing isfloat_string.
3959 This function checks for valid syntax and produces the resulting
3960 Lisp float number too. Rework it so that string-to-number
3961 no longer mishandles examples like "1.0e+". Use strtoumax,
3962 so that overflow for non-base-10 numbers is reported only when
3963 there's no portable and simple way to convert to floating point.
3964
3965 * textprop.c (set_text_properties_1): Rewrite for clarity,
3966 and to avoid GCC warning about integer overflow.
3967
3968 * intervals.h (struct interval): Use EMACS_INT for members
3969 where EMACS_UINT might cause problems. See
3970 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
3971 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
3972 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
3973 All uses changed.
3974 (offset_intervals): Tell GCC not to worry about length overflow
3975 when negating a negative length.
3976
3977 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
3978 (overrun_check_free): Likewise.
3979
3980 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
3981 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
3982 word size.
3983
3984 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3985 (gnutls_make_error): Rename local to avoid shadowing.
3986 (gnutls_emacs_global_deinit): ifdef out; not used.
3987 (Fgnutls_boot): Use const for pointer to readonly storage.
3988 Comment out unused local. Fix pointer signedness problems.
3989
3990 * lread.c (openp): Don't stuff size_t into an 'int'.
3991 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
3992 about possible signed overflow.
3993
3994 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3995 (GDK_KEY_g): Don't define if already defined.
3996 (xg_prepare_tooltip): Avoid pointer signedness problem.
3997 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
3998
3999 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
4000 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
4001
4002 * xfns.c (Fx_window_property): Simplify a bit,
4003 to make a bit faster and to avoid GCC 4.6.0 warning.
4004 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
4005
4006 * fns.c (internal_equal): Don't assume size_t fits in int.
4007
4008 * alloc.c (compact_small_strings): Tighten assertion a little.
4009
4010 Replace pEd with more-general pI, and fix some printf arg casts.
4011 * lisp.h (pI): New macro, generalizing old pEd macro to other
4012 conversion specifiers. For example, use "...%"pI"d..." rather
4013 than "...%"pEd"...".
4014 (pEd): Remove. All uses replaced with similar uses of pI.
4015 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
4016 * alloc.c (check_pure_size): Don't overflow by converting size to int.
4017 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
4018 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
4019 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
4020 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
4021 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
4022 64-bit hosts.
4023 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
4024 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
4025 * print.c (safe_debug_print, print_object): Likewise.
4026 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
4027 to int.
4028 Use pI instead of if-then-else-abort. Use %p to avoid casts,
4029 avoiding the 0 flag, which is not portable.
4030 * process.c (Fmake_network_process): Use pI to avoid cast.
4031 * region-cache.c (pp_cache): Likewise.
4032 * xdisp.c (decode_mode_spec): Likewise.
4033 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
4034 behavior on 64-bit hosts with printf arg.
4035 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
4036 (x_stop_queuing_selection_requests): Likewise.
4037 (x_get_window_property): Don't truncate byte count to an 'int'
4038 when tracing.
4039
4040 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
4041 here, since it parses constructs like leading '-' and spaces,
4042 which are not wanted; and it overflows with large numbers.
4043 Instead, simply match F[0-9]+, which is what is wanted anyway.
4044
4045 * alloc.c: Remove unportable assumptions about struct layout.
4046 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
4047 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
4048 (allocate_vectorlike, make_pure_vector): Use the new macros,
4049 plus offsetof, to remove unportable assumptions about struct layout.
4050 These assumptions hold on all porting targets that I know of, but
4051 they are not guaranteed, they're easy to remove, and removing them
4052 makes further changes easier.
4053
4054 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
4055 This doesn't fix a bug but makes the code clearer.
4056 (string_overrun_cookie): Now const. Use initializers that
4057 don't formally overflow signed char, to avoid warnings.
4058 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
4059 can cause Emacs to crash when string overrun checking is enabled.
4060 (allocate_buffer): Don't assume sizeof (struct buffer) is a
4061 multiple of sizeof (EMACS_INT); it need not be, if
4062 alignof(EMACS_INT) < sizeof (EMACS_INT).
4063 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
4064
40652011-04-26 Juanma Barranquero <lekktu@gmail.com>
4066
4067 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
4068

4070
4071 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
4072 supposed to be handshaking. (Bug#8556)
4073 Reported by Paul Eggert <eggert@cs.ucla.edu>.
4074
40752011-04-26 Daniel Colascione <dan.colascione@gmail.com>
4076
4077 * lisp.h (Qdebug): List symbol.
4078 * eval.c (Qdebug): Restore global linkage.
4079 * keyboard.c (debug-on-event): New variable.
4080 (handle_user_signal): Break into debugger when debug-on-event
4081 matches the current signal symbol.
4082
40832011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
4084
4085 * alloc.c (check_sblock, check_string_bytes)
4086 (check_string_free_list): Convert to standard C.
4087
40882011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
4089
4090 * w32.c (emacs_gnutls_push): Fix typo.
4091
40922011-04-25 Eli Zaretskii <eliz@gnu.org>
4093
4094 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
4095 "cast to pointer from integer of different size".
4096
4097 Improve doprnt and its use in verror. (Bug#8545)
4098 * doprnt.c (doprnt): Document the set of format control sequences
4099 supported by the function. Use SAFE_ALLOCA instead of always
4100 using `alloca'.
4101
4102 * eval.c (verror): Don't limit the buffer size at size_max-1, that
4103 is one byte too soon. Don't use xrealloc; instead xfree and
4104 xmalloc anew.
4105
41062011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
4107
4108 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
4109 callbacks stage.
4110
4111 * gnutls.c: Renamed global_initialized to
4112 gnutls_global_initialized. Added internals for the
4113 :verify-hostname-error, :verify-error, and :verify-flags
4114 parameters of `gnutls-boot' and documented those parameters in the
4115 docstring. Start callback support.
4116 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
4117 unless a fatal error occurred. Call gnutls_alert_send_appropriate
4118 on error. Return error code.
4119 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
4120 (emacs_gnutls_read): Likewise.
4121 (Fgnutls_boot): Return handshake error code.
4122 (emacs_gnutls_handle_error): New function.
4123 (wsaerror_to_errno): Likewise.
4124

4126 (emacs_gnutls_push): Likewise.
4127
4128 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
4129 (emacs_gnutls_push): Likewise.
4130
41312011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
4132
4133 * process.c (wait_reading_process_output): Check if GnuTLS
4134 buffered some data internally if no FDs are set for TLS
4135 connections.
4136
4137 * makefile.w32-in (OBJ2): Add gnutls.$(O).
4138 (LIBS): Link to USER_LIBS.

4140
41412011-04-24 Eli Zaretskii <eliz@gnu.org>
4142
4143 * xdisp.c (handle_single_display_spec): Rename the
4144 display_replaced_before_p argument into display_replaced_p, to
4145 make it consistent with the commentary. Fix typos in the
4146 commentary.
4147
4148 * textprop.c (syms_of_textprop): Remove dead code.
4149 (copy_text_properties): Delete obsolete commentary about an
4150 interface that was deleted long ago. Fix typos in the description
4151 of arguments.
4152
4153 * msdos.c (XMenuActivate, XMenuAddSelection): Adjust argument list
4154 to changes in oldXMenu/XMenu.h from 2011-04-16.
4155 <menu_help_message, prev_menu_help_message>: Constify.
4156 (IT_menu_make_room): menu->help_text is now `const char **';
4157 adjust.
4158
4159 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
4160 to changes in oldXMenu/XMenu.h from 2011-04-16.
4161 (struct XMenu): Declare `help_text' `const char **'.
4162
4163 * xfaces.c <Qunspecified>: Make extern again.
4164
4165 * syntax.c: Include sys/types.h before including regex.h, as
4166 required by Posix.
4167
4168 * doc.c (get_doc_string): Improve the format passed to `error'.
4169
4170 * doprnt.c (doprnt): Improve commentary.
4171
4172 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
4173
4174 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
4175 them with etags.
4176
4177 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
4178 changes in globals.h immediately force recompilation.
4179 (TAGS): Depend on $(CURDIR)/m/intel386.h and
4180 $(CURDIR)/s/ms-w32.h.

4312 it.
4313
4314 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,

4421
4422 * nsfont.m: Fixed bugs in ns_get_family and
4423 ns_descriptor_to_entity that were caused by using free to
4424 deallocate memory blocks that were allocated by xmalloc (via

4426 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
4427 --enable-checking=xmallocoverrun). xfree is now used to
4428 deallocate these memory blocks.

4671 * editfns.c, lisp.h (get_operating_system_release): Remove.
4672 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
4673 worth the hassle of breaking this out.
4674
4675 * xterm.c: Make symbols static if they're not exported.
4676 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

4782 so that it's not optimized away.
4783 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
4784 * dispextern.h (bidi_dump_cached_states): Remove, since it's
4785 exported only to the debugger.
4786
4787 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
4788 * atimer.h (run_all_atimers): Remove; not exported.
4789
4790 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
4791 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
4792 was inaccessible from Lisp.

4795
4796 alloc.c: Import and export fewer symbols, and remove unused items.
4797 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
4798 is defined.
4799 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
4800 it's not optimized away by whole-program optimization.

4816 Declare Lisp_Object Q* variables to be 'static' if not exported.
4817 This makes it easier for human readers (and static analyzers)
4818 to see whether these variables are used from other modules.
4819 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
4820 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

4830 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
4831
4832 * lisp.h (DEFINE_FUNC): Make sname 'static'.
4833
4834 Make Emacs functions such as Fatom 'static' by default.
4835 This makes it easier for human readers (and static analyzers)
4836 to see whether these functions can be called from other modules.
4837 DEFUN now defines a static function. To make the function external
4838 so that it can be used in other C modules, use the new macro DEFUE.
4839 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
4840 (Finit_image_library):
4841 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
4842 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
4843 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
4844 Remove decls, since these functions are now static.
4845 (Funintern, Fget_internal_run_time): New decls, since these functions
4846 were already external.
4847
4848 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
4849 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

4854 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
4855 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
4856 Mark functions with DEFUE instead of DEFUN,
4857 if they are used in other modules.
4858 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
4859 decls for now-static functions.
4860 * buffer.h (Fdelete_overlay): Remove decl.
4861 * callproc.c (Fgetenv_internal): Mark as internal.
4862 * composite.c (Fremove_list_of_text_properties): Remove decl.

4888

4890
48912011-04-14 Andreas Schwab <schwab@linux-m68k.org>
4892
4893 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
4894 change. (Bug#8496)
4895
48962011-04-13 Eli Zaretskii <eliz@gnu.org>
4897
4898 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
4899 when at ZV. (Bug#8487)
4900
49012011-04-12 Andreas Schwab <schwab@linux-m68k.org>
4902
4903 * charset.c (Fclear_charset_maps): Use xfree instead of free.
4904 (Bug#8437)
4905 * keyboard.c (parse_tool_bar_item): Likewise.
4906 * sound.c (sound_cleanup, alsa_close): Likewise.

4910
4911 * alloc.c (overrun_check_malloc, overrun_check_realloc)
4912 (overrun_check_free): Protoize.
4913
49142011-04-12 Paul Eggert <eggert@cs.ucla.edu>
4915
4916 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
4917 since callers should never pass a negative size.
4918 Change the signature to match that of plain 'read' and 'write'; see
4919 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
4920 * lisp.h: Update prototypes of emacs_write and emacs_read.
4921
49222011-04-11 Eli Zaretskii <eliz@gnu.org>
4923
4924 * xdisp.c (redisplay_window): Don't try to determine the character
4925 position of the scroll margin if the window start point w->startp
4926 is outside the buffer's accessible region. (Bug#8468)
4927
49282011-04-10 Eli Zaretskii <eliz@gnu.org>
4929
4930 Fix write-region and its subroutines for buffers > 2GB.
4931 * fileio.c (a_write, e_write): Modify declaration of arguments and
4932 local variables to support buffers larger than 2GB.
4933 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
4934
4935 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
4936 argument, local variables, and return value.
4937
4938 * lisp.h: Update prototypes of emacs_write and emacs_read.
4939
4940 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
4941
49422011-04-10 Paul Eggert <eggert@cs.ucla.edu>
4943
4944 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
4945
4946 Fix more problems found by GCC 4.6.0's static checks.
4947
4948 * xdisp.c (vmessage): Use a better test for character truncation.
4949
4950 * charset.c (load_charset_map): <, not <=, for optimization,
4951 and to avoid potential problems with integer overflow.
4952 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
4953 * casetab.c (set_identity, shuffle): Likewise.
4954 * editfns.c (Fformat): Likewise.
4955 * syntax.c (skip_chars): Likewise.
4956
4957 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
4958 This also lets GCC 4.6.0 generate slightly better loop code.
4959
4960 * callint.c (Fcall_interactively): <, not <=, for optimization.
4961 (Fcall_interactively): Count the number of arguments produced,
4962 not the number of arguments given. This is simpler and lets GCC
4963 4.6.0 generate slightly better code.
4964
4965 * ftfont.c: Distingish more carefully between FcChar8 and char.
4966 The previous code passed unsigned char * to a functions like
4967 strlen and xstrcasecmp that expect char *, which does not
4968 conform to the C standard.
4969 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
4970 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
4971 char * when the C standard requires it.
4972
4973 * keyboard.c (read_char): Remove unused var.
4974
4975 * eval.c: Port to Windows vsnprintf (Bug#8435).
4976 Include <limits.h>.
4977 (SIZE_MAX): Define if the headers do not.
4978 (verror): Do not give up if vsnprintf returns a negative count.
4979 Instead, grow the buffer. This ports to Windows vsnprintf, which
4980 does not conform to C99. Problem reported by Eli Zaretskii.
4981 Also, simplify the allocation scheme, by avoiding the need for
4982 calling realloc, and removing the ALLOCATED variable.
4983
4984 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
4985
4986 Remove invocations of doprnt, as Emacs now uses vsnprintf.
4987 But keep the doprint source code for now, as we might revamp it
4988 and use it again (Bug#8435).
4989 * lisp.h (doprnt): Remove.
4990 * Makefile.in (base_obj): Remove doprnt.o.
4991 * deps.mk (doprnt.o): Remove.
4992
4993 error: Print 32- and 64-bit integers portably (Bug#8435).
4994 Without this change, on typical 64-bit hosts error ("...%d...", N)
4995 was used to print both 32- and 64-bit integers N, which relied on
4996 undefined behavior.
4997 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
4998 New macro.
4999 * lisp.h (error, verror): Mark as printf-like functions.
5000 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
5001 Report overflow in size calculations when allocating printf buffer.
5002 Do not truncate output string at its first null byte.
5003 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
5004 Truncate the output at a character boundary, since vsnprintf does not
5005 do that.
5006 * charset.c (check_iso_charset_parameter): Convert internal
5007 character to string before calling 'error', since %c now has the
5008 printf meaning.
5009 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
5010 overflow when computing char to be passed to 'error'. Do not
5011 pass Lisp_Object to 'error'; pass the integer instead.
5012 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
5013 formatted with plain %d.

5016
5017 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.

5045
5046 * xterm.c (handle_one_xevent):
5047 * xmenu.c (create_and_show_popup_menu):
5048 * xselect.c (x_decline_selection_request)
5049 (x_reply_selection_request): Avoid type-punned deref of X events.

5097
5098 * process.c (Fformat_network_address): Doc fix.
5099
51002011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)

5150 This avoids several warnings with gcc -Wstrict-overflow.
5151 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
5152 directly, rather than having caller test rule sign. This avoids
5153 some unnecessary tests.
5154 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
5155 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
5156 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

5170 by using the new macro.
5171
5172 * textprop.c (set_text_properties_1): Change while to do-while,
5173 since the condition is always true at first.
5174
5175 * intervals.c (graft_intervals_into_buffer): Mark var as used.
5176 (interval_deletion_adjustment): Return unsigned value.
5177 All uses changed.

5198 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
5199
5200 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
5201 (font_score): Avoid potential overflow in diff calculation.
5202
5203 * fns.c (substring_both): Remove var that is set but not used.
5204 (sxhash): Redo loop for clarity and to avoid wraparound warning.
5205
5206 * eval.c (funcall_lambda): Rename local to avoid shadowing.
5207
5208 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
5209 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
5210 can always succeed if overflow has undefined behavior.
5211
5212 * search.c (boyer_moore, wordify): Remove vars set but not used.
5213 (wordify): Omit three unnecessary tests.
5214

5237
5238 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
5239
5240 * image.c (lookup_image): Remove var that is set but not used.
5241 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
5242
5243 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
5244 that are set but not used.
5245
5246 * xfns.c (make_invisible_cursor): Don't return garbage
5247 if XCreateBitmapFromData fails (Bug#8410).
5248
5249 * xselect.c (x_get_local_selection, x_handle_property_notify):
5250 Remove vars that are set but not used.

5258 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
5259 Check for overflow.
5260
5261 * xfaces.c (realize_named_face): Remove vars that are set but not used.
5262 (map_tty_color) [!defined MSDOS]: Likewise.
5263
5264 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
5265
5266 * coding.c: Remove vars that are set but not used.
5267 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
5268 All callers changed.
5269 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
5270 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):

5276 * print.c (print_object): Remove var that is set but not used.
5277
5278 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
5279 The gnulib version avoids calling malloc in the usual case,
5280 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
5281 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
5282 * filelock.c (current_lock_owner): Likewise.
5283 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
5284 * sysdep.c: Include allocator.h, careadlinkat.h.
5285 (emacs_no_realloc_allocator): New static constant.
5286 (emacs_readlink): New function.
5287 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
5288 ../lib/careadlinkat.h.
5289

5291
5292 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
5293 first non-nil return value).
5294
52952011-04-03 Jan Djärv <jan.h.d@swipnet.se>
5296
5297 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
5298 if not defined (Bug#8403).
5299
53002011-04-02 Juanma Barranquero <lekktu@gmail.com>
5301
5302 * xdisp.c (display_count_lines): Remove parameter `start',
5303 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

5349 * image.c (parse_image_spec): Use Ffunctionp.
5350
5351 * fns.c (concat, mapcar1): Accept byte-code-functions.
5352
5353 * eval.c (Fsetq): Handle lexical vars.
5354 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
5355 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
5356 (FletX, Flet): Obey lexical binding.
5357 (Fcommandp): Handle closures.
5358 (Feval): New `lexical' arg.
5359 (eval_sub): New function extracted from Feval. Use it almost
5360 everywhere where Feval was used. Look up vars in lexical env.
5361 Handle closures.
5362 (Ffunctionp): Move from subr.el.
5363 (Ffuncall): Handle closures.
5364 (apply_lambda): Remove `eval_flags'.
5365 (funcall_lambda): Handle closures and new byte-code-functions.
5366 (Fspecial_variable_p): New function.
5367 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
5368 but without exporting it to Lisp.
5369
5370 * doc.c (Fdocumentation, store_function_docstring):
5371 * data.c (Finteractive_form): Handle closures.
5372
5373 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
5374 interactive spec.

5377 New byte-codes.
5378 (exec_byte_code): New function extracted from Fbyte_code to handle new
5379 calling convention for byte-code-functions. Add new byte-codes.
5380
5381 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
5382

5391 * xdisp.c (SCROLL_LIMIT): New macro.
5392 (try_scrolling): Use it when setting scroll_limit.
5393 Limit scrolling to 100 screen lines.
5394 (redisplay_window): Even when falling back on "recentering",
5395 position point in the window according to scroll-conservatively,
5396 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
5397
5398 (try_scrolling): When point is above the window, allow searching
5399 as far as scroll_max, or one screenful, to compute vertical
5400 distance from PT to the scroll margin position. This prevents
5401 try_scrolling from unnecessarily failing when
5402 scroll-conservatively is set to a value slightly larger than the
5403 window height. Clean up the case of PT below the margin at bottom
5404 of window: scroll_max can no longer be INT_MAX. When aggressive
5405 scrolling is in use, don't let point enter the opposite scroll
5406 margin as result of the scroll.
5407 (syms_of_xdisp) <scroll-conservatively>: Document the
5408 threshold of 100 lines for never-recentering scrolling.
5409

5417 (redisplay_internal): Remove parameter `preserve_echo_area',
5418 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
5419
5420 * indent.c (Fvertical_motion):
5421 * window.c (window_scroll_pixel_based, Frecenter):
5422 Don't pass `need_y_p' to `move_it_by_lines'.
5423
54242011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
5425
5426 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
5427 steal a few bits to be more compact.
5428 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
5429 Remove unneeded casts.
5430
5431 * bytecode.c (Fbyte_code): CAR and CDR can GC.
5432
54332011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
5434
5435 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
5436 binding" message (bug#7967).
5437
54382011-03-30 Paul Eggert <eggert@cs.ucla.edu>
5439
5440 Fix more problems found by GCC 4.6.0's static checks.
5441
5442 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
5443 Remove unused local var.
5444
5445 * editfns.c (Fmessage_box): Remove unused local var.
5446
5447 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
5448 (note_mode_line_or_margin_highlight, note_mouse_highlight):
5449 Omit unused local vars.
5450 * window.c (shrink_windows): Omit unused local var.
5451 * menu.c (digest_single_submenu): Omit unused local var.
5452 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
5453 Omit unused local var.
5454
5455 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
5456 Don't assume string length fits in int.
5457 (keyremap_step, read_key_sequence): Use size_t for sizes.
5458 (read_key_sequence): Don't check last_real_key_start redundantly.
5459
5460 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
5461 instead of alloca (Bug#8344).
5462
5463 * eval.c (Fbacktrace): Don't assume nargs fits in int.
5464 (Fbacktrace_frame): Don't assume nframes fits in int.
5465
5466 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
5467
5468 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
5469 concerns.
5470
5471 * term.c (produce_glyphless_glyph): Remove unnecessary test.
5472
5473 * cm.c (calccost): Turn while-do into do-while, for clarity.
5474
5475 * keyboard.c (syms_of_keyboard): Use the same style as later
5476 in this function when indexing through an array. This also
5477 works around GCC bug 48267.
5478
5479 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
5480
5481 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

5484 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
5485
5486 * keyboard.c, keyboard.h (num_input_events): Now size_t.
5487 This avoids undefined behavior on integer overflow, and is a bit
5488 more convenient anyway since it is compared to a size_t variable.
5489
5490 Variadic C functions now count arguments with size_t, not int.
5491 This avoids an unnecessary limitation on 64-bit machines, which
5492 caused (substring ...) to crash on large vectors (Bug#8344).

5502 * fns.c (concat): Likewise.
5503 * frame.c (x_set_frame_parameters): Likewise.
5504 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
5505 0 if not found, not -1. All callers changed.
5506
5507 * alloc.c (garbage_collect): Don't assume stack size fits in int.
5508 (stack_copy_size): Now size_t, not int.
5509 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

5518 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
5519 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

5532 (Qcommand_hook_internal): Remove, unused.
5533 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
5534 Vcommand_hook_internal.
5535
5536 * eval.c (enum run_hooks_condition): Remove.
5537 (funcall_nil, funcall_not): New functions.

5542 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
5543

5545
5546 * dispextern.h (string_buffer_position): Remove declaration.
5547
5548 * print.c (strout): Remove parameter `multibyte', unused since
5549 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
5550
5551 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
5552 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
5553 All callers changed.

5556
5557 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
5558 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.

5597
5598 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
5599 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
5600
56012011-03-26 Juanma Barranquero <lekktu@gmail.com>
5602
5603 * w32.c (read_unc_volume): Use parameter `henum', instead of
5604 global variable `wget_enum_handle'.
5605
5606 * keymap.c (describe_vector): Remove parameters `indices' and
5607 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

5721
5722 Fix more problems found by GCC 4.5.2's static checks.
5723
5724 * coding.c (encode_coding_raw_text): Avoid unnecessary test
5725 the first time through the loop, since we know p0 < p1 then.
5726 This also avoids a gcc -Wstrict-overflow warning.
5727
5728 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
5729 leading to a memory leak, possible in functions like
5730 load_charset_map_from_file that can allocate an unbounded number
5731 of objects (Bug#8318).
5732
5733 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
5734 that could (at least in theory) be that large.
5735
5736 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
5737 This is less likely to overflow, and avoids undefined behavior if
5738 overflow does occur. All callers changed. Use strtoul to scan
5739 for the unsigned long integer.
5740 (pint2hrstr): Simplify and tune code slightly.
5741 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

5753
5754 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
5755
5756 * process.c (Fmake_network_process): Use socklen_t, not int,
5757 where POSIX says socklen_t is required in portable programs.
5758 This fixes a porting bug on hosts like 64-bit HP-UX, where
5759 socklen_t is wider than int (Bug#8277).
5760 (Fmake_network_process, server_accept_connection):
5761 (wait_reading_process_output, read_process_output):

5773
5774 Make tparam.h and terminfo.c consistent.
5775 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
5776 Include tparam.h instead, since it declares them.
5777 * cm.h (PC): Remove extern decl; tparam.h now does this.
5778 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
5779 * terminfo.c: Include tparam.h, to check interfaces.
5780 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
5781 (tparam): Adjust signature to match interface in tparam.h;
5782 this removes some undefined behavior. Check that outstring and len
5783 are zero, which they always are with Emacs.
5784 * tparam.h (PC, BC, UP): New extern decls.
5785
5786 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
5787 (xftfont_open): Rename locals to avoid shadowing.
5788
5789 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

5795 Rename locals to avoid shadowing.
5796
5797 * xfont.c (xfont_list_family): Mark var as initialized.
5798
5799 * xml.c (make_dom): Now static.
5800
5801 * composite.c (composition_compute_stop_pos): Rename local to
5802 avoid shadowing.
5803 (composition_reseat_it): Remove unused locals.
5804 (find_automatic_composition, composition_adjust_point): Likewise.
5805 (composition_update_it): Mark var as initialized.
5806 (find_automatic_composition): Mark vars as initialized,
5807 with a FIXME (Bug#8290).
5808
5809 character.h: Rename locals to avoid shadowing.
5810 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
5811 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
5812 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
5813 (BUF_DEC_POS): Be more systematic about renaming local temporaries
5814 to avoid shadowing.
5815

5823 Rename locals to avoid shadowing.
5824
5825 * sound.c (wav_play, au_play, Fplay_sound_internal):
5826 Fix pointer signedness.
5827 (alsa_choose_format): Remove unused local var.
5828 (wav_play): Initialize a variable to 0, to prevent undefined
5829 behavior (Bug#8278).
5830
5831 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
5832
5833 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
5834
5835 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
5836 clobbering (Bug#8298).
5837 * sysdep.c (sys_subshell): Likewise.
5838 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
5839
5840 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
5841 This should get cleaned up, so that child_setup has the
5842 same signature on all platforms.
5843
5844 * callproc.c (call_process_cleanup): Now static.
5845 (relocate_fd): Rename locals to avoid shadowing.

58472011-03-22 Chong Yidong <cyd@stupidchicken.com>
5848
5849 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
5850 not to be necessary, and produces flickering.
5851
58522011-03-20 Glenn Morris <rgm@gnu.org>
5853
5854 * config.in: Remove file.

5971 Move decls here, to check interfaces.
5972 * process.c (get_operating_system_release): Move decl to lisp.h.
5973 * xrdb.c (get_system_name): Likewise.
5974 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
5975 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
5976 some of which prompt warnings from gcc -Wbad-function-cast.
5977 (Fformat_time_string, Fencode_time, Finsert_char):
5978 (Ftranslate_region_internal, Fformat):
5979 Rename or remove local vars to avoid shadowing.

5986 ENABLE_CHECKING is not defined.
5987

6005 (GC_STRING_CHARS): Remove; not used.
6006 (Fmemory_limit): Cast sbrk's returned value to char *.
6007
6008 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

6010
6011 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
6012
6013 Use functions, not macros, for up- and down-casing (Bug#8254).
6014 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6015 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
6016 to use the following functions instead of these macros.
6017 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
6018 EMACS_INT, since callers assume the returned value fits in int.
6019 (upcase1): Likewise, for UPCASE_TABLE.
6020 (uppercasep, lowercasep, upcase): New static inline functions.
6021 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

6027 (regex_compile, re_search_2, re_match_2_internal):
6028 Remove unused local vars.
6029 (FREE_VAR): Rewrite so as not to use empty "else",
6030 which gcc can warn about.
6031 (regex_compile, re_match_2_internal): Mark locals as initialized.
6032 (RETALLOC_IF): Define only if needed.
6033 (WORDCHAR_P): Likewise. This one is never needed, but is used
6034 only in a comment talking about a compiler bug, so put inside
6035 the #if 0 of that comment.
6036 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
6037 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
6038 Remove; unused.

6049
6050 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
6051
6052 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
6053 All uses changed.
6054 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
6055 Rename locals to avoid shadowing.
6056 (Fvertical_motion): Mark locals as initialized.
6057
6058 * casefiddle.c (casify_object, casify_region): Now static.
6059 (casify_region): Mark local as initialized.
6060
6061 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
6062
6063 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
6064 New macros, so that the caller can use some names other than
6065 gcpro1, gcpro2, etc.
6066 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
6067 of the new macros.
6068 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
6069 argument, for consistency with GCPRO2_VAR, etc: it is now the
6070 prefix of the variable, not the variable itself. All uses
6071 changed.
6072 * dired.c (directory_files_internal, file_name_completion):
6073 Rename locals to avoid shadowing.
6074
6075 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
6076 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
6077 dired.c's scmp function, had undefined behavior.
6078 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6079 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
6080 * buffer.h: ... to here, because these macros use current_buffer,
6081 and the new implementation with inline functions needs to have
6082 current_buffer in scope now, rather than later when the macros
6083 are used.
6084 (downcase, upcase1): New static inline functions.
6085 (DOWNCASE, UPCASE1): Reimplement using these functions.
6086 This avoids undefined behavior in expressions like
6087 DOWNCASE (x) == DOWNCASE (y), which previously suffered
6088 from race conditions in accessing the global variables
6089 case_temp1 and case_temp2.
6090 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
6091 * lisp.h (case_temp1, case_temp2): Remove their decls.
6092 * character.h (ASCII_CHAR_P): Move from here ...
6093 * lisp.h: ... to here, so that the inline functions mentioned
6094 above can use them.
6095
6096 * dired.c (directory_files_internal_unwind): Now static.
6097
6098 * fileio.c (file_name_as_directory, directory_file_name):
6099 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
6100 Now static.
6101 (file_name_as_directory): Use const pointers when appropriate.
6102 (Fexpand_file_name): Likewise. In particular, newdir might
6103 point at constant storage, so make it a const pointer.
6104 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
6105 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
6106 signedness issues.
6107 (Fset_file_times, Finsert_file_contents, auto_save_error):
6108 Rename locals to avoid shadowing.
6109
6110 * minibuf.c (choose_minibuf_frame_1): Now static.
6111 (Ftry_completion, Fall_completions): Rename or remove locals
6112 to avoid shadowing.
6113
6114 * marker.c (bytepos_to_charpos): Remove; unused.
6115
6116 * lisp.h (verify_bytepos, count_markers): New decls,
6117 so that gcc does not warn that these functions aren't declared.
6118
6119 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
6120 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
6121 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
6122 (copy_text): Remove unused local var.
6123
6124 * filelock.c (within_one_second): Now static.
6125 (lock_file_1): Rename local to avoid shadowing.
6126
6127 * buffer.c (fix_overlays_before): Mark locals as initialized.
6128 (fix_start_end_in_overlays): Likewise. This function should be
6129 simplified by using pointers-to-pointers, but that's a different
6130 matter.
6131 (switch_to_buffer_1): Now static.
6132 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
6133 (report_overlay_modification): Rename locals to avoid shadowing.
6134
6135 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
6136 Fix pointer signedness issue.
6137 (sys_subshell): Mark local as volatile if checking for lint,
6138 to suppress a gcc -Wclobbered warning that does not seem to be right.
6139 (MAXPATHLEN): Define only if needed.
6140
6141 * process.c (serial_open, serial_configure): Move decls from here ...
6142 * systty.h: ... to here, so that they can be checked.
6143
6144 * fns.c (get_random, seed_random): Move extern decls from here ...
6145 * lisp.h: ... to here, so that they can be checked.
6146
6147 * sysdep.c (reset_io): Now static.
6148 (wait_for_termination_signal): Remove; unused.
6149
6150 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
6151 (copy_keymap_item, append_key, push_text_char_description):
6152 Now static.
6153 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
6154 (DENSE_TABLE_SIZE): Remove; unused.
6155 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
6156 (describe_map_tree):
6157 Rename locals to avoid shadowing.
6158
6159 * keyboard.c: Declare functions static if they are not used elsewhere.
6160 (echo_char, echo_dash, cmd_error, top_level_2):
6161 (poll_for_input, handle_async_input): Now static.
6162 (read_char, kbd_buffer_get_event, make_lispy_position):
6163 (make_lispy_event, make_lispy_movement, apply_modifiers):
6164 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):

6172 * alloc.c (mark_kboards): ... from here.
6173
6174 * lisp.h (force_auto_save_soon): New decl.
6175
6176 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
6177 (DEFINE_DUMMY_FUNCTION): New macro.
6178 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
6179 Use it.
6180 (main): Add casts to avoid warnings
6181 if GCC considers string literals to be constants.
6182
6183 * lisp.h (fatal_error_signal): Add decl, since it's exported.
6184
6185 * dbusbind.c: Pointer signedness fixes.
6186 (xd_signature, xd_append_arg, xd_initialize):
6187 (Fdbus_call_method, Fdbus_call_method_asynchronously):
6188 (Fdbus_method_return_internal, Fdbus_method_error_internal):
6189 (Fdbus_send_signal, xd_read_message_1, Fdbus_register_service):
6190 (Fdbus_register_signal): Use SSDATA when the context wants char *.
6191
6192 * dbusbind.c (Fdbus_init_bus): Add cast to avoid warning
6193 if GCC considers string literals to be constants.

6230 * w32menu.c (Qmenu_bar, QCtoggle, QCradio, Qoverriding_local_map)

6247 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
6248 Assign struct members directly, instead of using BUF_BEGV etc.
6249 (record_buffer_markers, fetch_buffer_markers): New functions for
