3 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
4 extra slot even if the purpose is char-code-property-table.
5
6 2011-08-19 Eli Zaretskii <eliz@gnu.org>
7
8 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
9 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
10 from an Org mode buffer to a Speedbar frame.
11
12 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13 a composition, take its buffer position from IT->cmp_it.charpos.
14 Fixes cursor positioning at the beginning of a line that begins
15 with a composed character.
16
17 2011-08-18 Eli Zaretskii <eliz@gnu.org>
18

21 in a buffer produced by `describe-categories'.
22
23 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
24 members before the level stack, so they would be saved and
25 restored when copying iterator state. Fixes incorrect reordering
26 around TABs covered by display properties.

43
44 2011-08-16 Ken Brown <kbrown@cornell.edu>
45
46 * gmalloc.c: Expand comment.
47
48 2011-08-16 Eli Zaretskii <eliz@gnu.org>
49
50 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate

105
106 * xdisp.c (move_it_in_display_line_to): Don't invoke

110
111 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
112
113 * nsterm.h (ns_run_ascript): Declare.

116 * nsfns.m (as_script, as_result, as_status): New static variables.
117 (ns_run_ascript): New function.
118 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
119 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start

121
122 * nsterm.m (sendEvent): If event is NSApplicationDefined and
123 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
124 the event loop (Bug#7276).
125
126 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
127
128 * gnutls.c (QCgnutls_bootprop_priority)

135 Qgnutls_bootprop_..., all uses changed.
136
137 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
138 uses changed.
139
140 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
141
142 * xfaces.c (Qframe_set_background_mode): Now static.
143 * dispextern.h (Qframe_set_background_mode): Remove decl.
144
145 * process.c (Fnetwork_interface_info): Declare local only if needed.
146
147 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
148
149 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
150 (Fnetwork_interface_list): Allocate in increments of bytes instead
151 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
152 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
153 sockaddr.
154 (struct ifflag_def): notrailers is smart on OSX.
155 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
156 Get hardware address with getifaddrs if available.

159
160 * xdisp.c (iterate_out_of_display_property): xassert that
161 IT->position is set to within IT->object's boundaries. Break from
162 the loop as soon as EOB is reached; avoids infloops in redisplay
163 when IT->position is set up wrongly due to some bug. Set
164 IT->current to match the bidi iterator unconditionally.
165 (push_display_prop): Allow GET_FROM_STRING as IT->method on
166 entry. Force push_it to save on the stack the current
167 buffer/string position, to be restored by pop_it. Fix flags in
168 the iterator structure wrt the object coming from a display
169 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
170 properties. (Bug#9284)
171
172 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
173
174 * fontset.c (fontset_get_font_group): Add proper type checks.
175 (Bug#9172)
176

180 and LC_VERSION_MIN_MACOSX.
181 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
182 (dump_it) [LC_FUNCTION_STARTS]: Use it.
183
184 2011-08-08 Eli Zaretskii <eliz@gnu.org>
185
186 * xdisp.c (forward_to_next_line_start): Allow to use the
187 no-display-properties-and-no-overlays under bidi display. Set
188 disp_pos in the bidi iterator to avoid searches for display
189 properties and overlays.
190
191 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
192
193 * editfns.c (Fset_time_zone_rule): Document relationship with the
194 setenv function.
195
196 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
197 the font entity extracted from the cache (Bug#8109).
198
199 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
200
201 * composite.c (autocmp_chars): Don't reset point. That is done by
202 restore_point_unwind (Bug#5984).
203
204 2011-08-07 Juri Linkov <juri@jurta.org>
205
206 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
207 to show the arg `TIME' instead of `TIMEVAL'.
208
209 2011-08-06 Eli Zaretskii <eliz@gnu.org>
210
211 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
212 display property strides EOL and includes a newline, as in
213 longlines-mode. (Bug#9254)
214 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
215 word-wrap under bidirectional display. (Bug#9224)
216
217 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
218 is non-zero, even if the data buffer is NULL. Fixes a crash in
219 vertical-motion with longlines-mode. (Bug#9254)
220
221 2011-08-05 Eli Zaretskii <eliz@gnu.org>
222
223 * bidi.c <bidi_cache_total_alloc>: Now static.
224 (bidi_initialize): Initialize bidi_cache_total_alloc.
225
226 *xdisp.c (display_line): Release buffer allocated for shelved bidi
227 cache. (Bug#9221)
228
229 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
230 amount allocated this far in `bidi_cache_total_alloc'.
231 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
232 non-zero, only free the data buffer without restoring the cache
233 contents. All callers changed.
234
235 * dispextern.h (bidi_unshelve_cache): Update prototype.
236
237 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
238 (move_it_in_display_line, move_it_to)
239 (move_it_vertically_backward, move_it_by_lines): Replace the call
240 to xfree to an equivalent call to bidi_unshelve_cache.
241 (move_it_in_display_line_to): Fix logic of returning
242 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
243
244 2011-08-05 Eli Zaretskii <eliz@gnu.org>
245
246 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
247 came from a string character with a `cursor' property. (Bug#9229)
248
249 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
250
251 * Makefile.in (LIB_PTHREAD): New variable.

262 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
263
264 * xterm.c (x_find_topmost_parent): New function.
265 (x_set_frame_alpha): Find topmost parent window with
266 x_find_topmost_parent and set the property there also (bug#9181).
267 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
268
269 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
270
271 * callproc.c (Fcall_process): Avoid vfork clobbering
272 the local vars buffer, coding_systems, current_dir.
273
274 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
275
276 * keymap.c (Fmake_composed_keymap): Move to subr.el.
277
278 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
279
280 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
281 so that it is not optimized away.
282
283 * xdisp.c (compute_display_string_pos): Remove unused local.
284
285 2011-08-02 Eli Zaretskii <eliz@gnu.org>
286
287 Fix slow cursor motion and scrolling in large buffers with
288 selective display, like Org Mode buffers. (Bug#9218)

291
292 * xdisp.c: Remove one-slot cache of display string positions.
293 (compute_display_string_pos): Accept an additional argument
294 DISP_PROP_P; callers changed. Scan at most 5K characters forward
295 for a display string or property. If found, set DISP_PROP_P
296 non-zero.
297
298 * bidi.c (bidi_fetch_char): Accept an additional argument
299 DISP_PROP_P, and pass it to compute_display_string_pos.
300 Only handle text covered by a display string if DISP_PROP_P is returned
301 non-zero. All callers of bidi_fetch_char changed.
302
303 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
304
305 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
306
307 2010-12-03 Don March <don@ohspite.net>
308
309 * keymap.c (Fdefine_key): Fix non-prefix key error message when
310 last character M-[char] is translated to ESC [char] (bug#7541).
311
312 2011-08-02 Kenichi Handa <handa@m17n.org>
313
314 * lisp.h (uniprop_table): Extern it.
315
316 * chartab.c (uniprop_table): Make it non-static.
317
318 2011-08-01 Eli Zaretskii <eliz@gnu.org>
319
320 * xdisp.c (forward_to_next_line_start): Accept additional argument
321 BIDI_IT_PREV, and store into it the state of the bidi iterator had
322 on the newline.
323 (reseat_at_next_visible_line_start): Use the bidi iterator state
324 returned by forward_to_next_line_start to restore the state of
325 it->bidi_it after backing up to previous newline. (Bug#9212)
326
327 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
328
329 * regex.c (re_comp): Protoize.
330 (re_exec): Fix return type.
331 (regexec): Fix type of `ret'. (Bug#9203)
332
333 2011-07-29 Paul Eggert <eggert@cs.ucla.edu>
334
335 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
336 This is needed if max-image-size is a floating-point number.
337
338 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
339
340 * print.c (print_object): Print empty symbol as ##.

345
346 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
347 setting frame foreground color (Bug#9175).
348 (x_set_background_color): Likewise.
349
350 * nsmenu.m (-setText): Size tooltip dimensions precisely to
351 contents (Bug#9176).
352 (EmacsTooltip -init): Remove bezels and add shadows to
353 tooltip windows.
354
355 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
356 or scroll bar (Bug#8470).
357
358 * nsfont.m (nsfont_open): Remove assignment to voffset and
359 unnecessary vars hshink, expand, hd, full_height, min_height.
360 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
361
362 * nsterm.h (nsfont_info): Remove voffset field.
363
364 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
365
366 Implement strike-through and overline on NextStep (Bug#8863).
367
368 * nsfont.m (nsfont_open): Use underline position provided by font,
369 instead of hard-coded value of 2.
370 (nsfont_draw): Call ns_draw_text_decoration instead.
371
372 * nsterm.h: Add declaration for ns_draw_text_decoration.
373
374 * nsterm.m (ns_draw_text_decoration): New function for drawing
375 underline, overline, and strike-through.

378 accomodate underlining, etc.
379
380 2011-07-28 Eli Zaretskii <eliz@gnu.org>
381
382 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
383 default.
384
385 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
386
387 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
388 Without this fix, if a signal arrives just after memory fills up,
389 'malloc' might be invoked reentrantly.
390
391 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
392 In other words, assume that every image size is allowed, on non-X
393 hosts. This assumption is probably wrong, but it lets Emacs compile.
394
395 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
396
397 * regex.c (re_iswctype): Convert return values to boolean.
398
399 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
400
401 * xdisp.c (compute_display_string_pos): Don't use cached display
402 string position if the buffer had its restriction changed.
403 (Bug#9184)
404
405 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
406
407 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
408
409 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
410
411 Integer signedness and overflow and related fixes. (Bug#9079)
412
413 * bidi.c: Integer size and overflow fixes.
414 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
415 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
416 (bidi_cache_find_level_change, bidi_cache_ensure_space)
417 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
418 (bidi_find_other_level_edge):
419 Use ptrdiff_t instead of EMACS_INT where either will do.
420 This works better on 32-bit hosts configured --with-wide-int.
421 (bidi_cache_ensure_space): Check for size-calculation overflow.
422 Use % rather than repeated addition, for better worst-case speed.
423 Don't set bidi_cache_size until after xrealloc returns, because it
424 might not return.
425 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
426 (bidi_cache_ensure_space): Also check that the bidi cache size
427 does not exceed that of the largest Lisp string or buffer. See Eli
428 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
429
430 * alloc.c (__malloc_size_t): Remove.
431 All uses replaced by size_t. See Andreas Schwab's note
432 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
433
434 * image.c: Improve checking for integer overflow.
435 (check_image_size): Assume that f is nonnull, since
436 it is always nonnull in practice. This is one less thing to
437 worry about when checking for integer overflow later.
438 (x_check_image_size): New function, which checks for integer
439 overflow issues inside X.
440 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
441 This removes the need for a memory_full check.
442 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
443 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
444 (xbm_read_bitmap_data): Change locals back to 'int', since
445 their values must fit in 'int'.
446 (xpm_load_image, png_load, tiff_load):
447 Invoke x_create_x_image_and_pixmap earlier,
448 to avoid much needless work if the image is too large.
449 (tiff_load): Treat overly large images as if
450 x_create_x_image_and_pixmap failed, not as malloc failures.
451 (gs_load): Use x_check_image_size.
452
453 * gtkutil.c: Omit integer casts.
454 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
455 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
456
457 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
458
459 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
460 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
461 would wrongly return t on a 64-bit host.
462
463 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
464 The plain *_OVERFLOW macros run afoul of GCC bug 49705
465 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
466 and therefore cause GCC to emit a bogus diagnostic in some cases.
467
468 * image.c: Integer signedness and overflow and related fixes.
469 This is not an exhaustive set of fixes, but it's time to
470 record what I've got.
471 (lookup_pixel_color, check_image_size): Remove redundant decls.
472 (check_image_size): Don't assume that arbitrary EMACS_INT values
473 fit in 'int', or that arbitrary 'double' values fit in 'int'.
474 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
475 (tiff_load, imagemagick_load_image):
476 Check for overflow in size calculations.
477 (x_create_x_image_and_pixmap): Remove unnecessary test for
478 xmalloc returning NULL; that can't happen.
479 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
480 (xpm_color_bucket): Use better integer hashing function.
481 (xpm_cache_color): Don't possibly over-allocate memory.
482 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
483 (gif_memory_source):
484 Use ptrdiff_t, not int or size_t, to record sizes.
485 (png_load): Don't assume values greater than 2**31 fit in 'int'.
486 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
487 either works, as we prefer signed integers.
488 (tiff_read_from_memory, tiff_write_from_memory):
489 Return tsize_t, not size_t, since that's what the TIFF API wants.
490 (tiff_read_from_memory): Don't fail simply because the read would
491 go past EOF; instead, return a short read.
492 (tiff_load): Omit no-longer-needed casts.
493 (Fimagemagick_types): Don't assume size fits into 'int'.
494
495 Improve hashing quality when configured --with-wide-int.
496 * fns.c (hash_string): New function, taken from sxhash_string.
497 Do not discard information about ASCII character case; this
498 discarding is no longer needed.
499 (sxhash-string): Use it. Change sig to match it. Caller changed.
500 * lisp.h: Declare it.
501 * lread.c (hash_string): Remove, since we now use fns.c's version.
502 The fns.c version returns a wider integer if --with-wide-int is
503 specified, so this should help the quality of the hashing a bit.
504
505 * emacs.c: Integer overflow minor fix.
506 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
507 Define only if GNU_LINUX.
508 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
509
510 * dispnew.c: Integer signedness and overflow fixes.
511 Remove unnecessary forward decls, that were a maintenance hassle.
512 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
513 All uses changed.
514 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
515 (scrolling_window): Use ptrdiff_t, not int, for byte count.
516 (prepare_desired_row, line_draw_cost):
517 Use int, not unsigned, where either works.
518 (save_current_matrix, restore_current_matrix):
519 Use ptrdiff_t, not size_t, where either works.
520 (init_display): Check for overflow more accurately, and without
521 relying on undefined behavior.
522
523 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
524 Remove, replacing with the new symbols in lisp.h. All uses changed.
525 * fileio.c (make_temp_name):
526 * filelock.c (lock_file_1, lock_file):
527 * xdisp.c (message_dolog):
528 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
529 Use pMd etc. instead.
530 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
531 replacing the pWIDE etc. symbols removed from editfns.c.
532
533 * keyboard.h (num_input_events): Now uintmax_t.
534 This is (very slightly) less likely to mess up due to wraparound.
535 All uses changed.
536
537 * buffer.c: Integer signedness fixes.
538 (alloc_buffer_text, enlarge_buffer_text):
539 Use ptrdiff_t rather than size_t when either will do, as we prefer
540 signed integers.
541
542 * alloc.c: Integer signedness and overflow fixes.
543 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
544 (__malloc_size_t): Default to size_t, not to int.
545 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
546 (Fgarbage_collect, mark_object_loop_halt, mark_object):
547 Prefer ptrdiff_t to size_t when either would do, as we prefer
548 signed integers.
549 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
550 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
551 Now const. Initialize with values that are in range even if char
552 is signed.
553 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
554 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
555 These functions do the right thing with sizes > 2**32.
556 (check_depth): Now ptrdiff_t, not int.
557 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
558 Adjust to new way of storing sizes. Check for size overflow bugs
559 in rest of code.
560 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
561 slightly wrong anyway, as it missed one instance of
562 XMALLOC_OVERRUN_CHECK_OVERHEAD.
563 (refill_memory_reserve): Omit needless cast to size_t.
564 (mark_object_loop_halt): Mark as externally visible.
565
566 * xselect.c: Integer signedness and overflow fixes.
567 (Fx_register_dnd_atom, x_handle_dnd_message):
568 Use ptrdiff_t, not size_t, since we prefer signed.
569 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
570 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
571 x_dnd_atoms_size and x_dnd_atoms_length.
572
573 * doprnt.c: Prefer signed to unsigned when either works.
574 * eval.c (verror):
575 * doprnt.c (doprnt):
576 * lisp.h (doprnt):
577 * xdisp.c (vmessage):
578 Use ptrdiff_t, not size_t, when using or implementing doprnt,
579 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
580 prefer signed arithmetic to avoid comparison confusion.
581 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
582 but is a bit tricky.
583
584 Assume freestanding C89 headers, string.h, stdlib.h.
585 * data.c, doprnt.c, floatfns.c, print.c:
586 Include float.h unconditionally.
587 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
588 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
589 * regex.c: Likewise for stddef.h, string.h.
590 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
591 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
592 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
593 (STDC_HEADERS): Remove obsolete defines.
594 * sysdep.c: Include limits.h unconditionally.
595
596 Assume support for memcmp, memcpy, memmove, memset.
597 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
598 * regex.c (memcmp, memcpy):
599 Remove; we assume C89 now.
600
601 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
602 (__malloc_safe_bcopy): Remove; no longer needed.
603
604 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
605 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
606 well either way, and we prefer signed to unsigned.
607
608 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
609
610 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
611 closes the connection while we're reading (bug#9182).
612
613 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
614
615 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
616 are specified (Bug#9168).
617
618 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
619
620 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
621 Found by GCC static checking and --with-wide-int on a 32-bit host.
622
623 2011-07-25 Eli Zaretskii <eliz@gnu.org>
624
625 * xdisp.c (compute_display_string_pos): Fix logic of caching
626 previous display string position. Initialize cached_prev_pos to
627 -1. Fixes slow-down at the beginning of a buffer.
628
629 2011-07-24 Eli Zaretskii <eliz@gnu.org>
630
631 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
632 for attrs[LFACE_FONTSET_INDEX].
633
634 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
635
636 * xml.c (parse_region): Remove unused local
637 that was recently introduced.
638
639 2011-07-23 Eli Zaretskii <eliz@gnu.org>
640
641 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
642 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
643
644 * xdisp.c (move_it_in_display_line_to): Record the best matching
645 position for TO_CHARPOS while scanning the line, and restore it on
646 exit if none of the characters scanned was an exact match.
647 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
648 when exact match is impossible due to invisible text, and the
649 lines are truncated.
650
651 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
652
653 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
654 for OSX >= 10.7.
655
656 2011-07-22 Eli Zaretskii <eliz@gnu.org>
657
658 Fix a significant slow-down of cursor motion with C-n, C-p,
659 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
660 auto-repeat under bidi redisplay in fontified buffers.
661 * xdisp.c (compute_stop_pos_backwards): New function.
662 (next_element_from_buffer): Call compute_stop_pos_backwards to
663 find a suitable prev_stop when we find ourselves before
664 base_level_stop.
665 (reseat): Don't look for prev_stop, as that could mean a very long
666 run.
667 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
668 <cached_disp_overlay_modiff>: Cache for last found display string
669 position.
670 (compute_display_string_pos): Return the cached position if asked
671 about the same buffer in the same area of character positions, and
672 the buffer wasn't changed since the time the display string
673 position was cached.
674
675 2011-07-22 Eli Zaretskii <eliz@gnu.org>
676
677 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
678 is an integer, which is important for empty lines. (Bug#9149)
679
680 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
681
682 * frame.c (Fmodify_frame_parameters): In tty case, update the
683 default face if necessary (Bug#4238).
684
685 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
686
687 * editfns.c (Fstring_to_char): No need to explain what a character
688 is in the docstring (Bug#6576).
689
690 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
691
692 * xml.c (parse_region): Make sure we always return a tree.
693
694 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
695
696 * xml.c (parse_region): If a document contains only comments,
697 return that, too.
698
699 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
700
701 * xml.c (make_dom): Return comments, too.
702
703 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
704
705 Port to OpenBSD.
706 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
707 and the surrounding thread.
708 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
709 rather than fgets, and retry after EINTR. Otherwise, 'emacs
710 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
711 timer goes off.
712 * s/openbsd.h (BROKEN_SIGIO): Define.
713 * unexelf.c (unexec) [__OpenBSD__]:
714 Don't update the .mdebug section of the Alpha COFF symbol table.
715
716 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
717
718 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
719 (bug#8460).
720
721 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
722
723 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
724 This fixes some race conditions on the permissions of any newly
725 created file.
726
727 * alloc.c (valid_pointer_p): Use pipe, not open.
728 This fixes some permissions issues when debugging.
729
730 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
731 If fchown fails to set both uid and gid, try to set just gid,
732 as that is sometimes allowed. Adjust the file's mode to eliminate
733 setuid or setgid bits that are inappropriate if fchown fails.
734
735 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
736
737 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
738 to compare Lisp_Objects.
739 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
740 global_gnutls_log_level, don't mistake it for a Lisp_Object.
741 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
742
743 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
744
745 * lread.c (read_integer): Unread even EOF character.
746 (read1): Likewise. Properly record start position of symbol.
747
748 * lread.c (read1): Read `#:' as empty uninterned symbol if no
749 symbol character follows.
750
751 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
752
753 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
754 This works around a problem with the previous change to Fcopy_file.
755 Recent glibc declares fchown with __attribute__((warn_unused_result)),
756 and without this change, GCC might complain about discarding
757 fchown's return value.
758
759 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
760
761 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
762
763 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
764
765 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
766
767 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
768
769 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
770 it's used from the C level.
771
772 * process.c: Use the same condition for POLL_FOR_INPUT in both
773 keyboard.c and process.c (bug#1858).
774
775 2011-07-09 Lawrence Mitchell <wence@gmx.li>
776
777 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
778 (Fgnutls_boot): Use it.
779
780 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
781
782 * doc.c (Fsubstitute_command_keys): Revert last change.
783
784 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
785
786 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
787 quotes the next character, and doesn't affect other longer
788 sequences (bug#8935).
789
790 * lread.c (syms_of_lread): Clarify that is isn't only
791 `eval-buffer' and `eval-defun' that's affected by
792 `lexical-binding' (bug#8460).
793
794 2011-07-15 Eli Zaretskii <eliz@gnu.org>
795
796 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
797 bidi redisplay when a line includes both an image and is
798 truncated.
799
800 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
801
802 Fix minor problems found by static checking.
803 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
804 (elsz): Now a signed constant, not a size_t var. We prefer signed
805 types to unsigned, to avoid integer comparison confusion. Without
806 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
807 "cannot optimize loop, the loop counter may overflow", a symptom
808 of the confusion.
809 * indent.c (Fvertical_motion): Mark locals as initialized.
810 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
811
812 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
813
814 * search.c (Fre_search_backward): Mention `case-fold-search' in
815 all the re_search_* functions (bug#8138).
816
817 * keyboard.c (Fopen_dribble_file): Document when the file is
818 closed (bug#8056).
819
820 2011-07-14 Eli Zaretskii <eliz@gnu.org>
821
822 * bidi.c (bidi_dump_cached_states): Fix format of displaying
823 bidi_cache_idx.
824
825 Support bidi reordering of display and overlay strings.
826 * xdisp.c (compute_display_string_pos)
827 (compute_display_string_end): Accept additional argument STRING.
828 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
829 (reseat_to_string): Initialize bidi_it->string.s and
830 bidi_it->string.schars.
831 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
832 NULL (avoids a crash in bidi_paragraph_init).
833 Initialize itb.string.lstring.
834 (init_iterator): Call bidi_init_it only of a valid
835 buffer position was specified. Initialize paragraph_embedding to
836 L2R.
837 (reseat_to_string): Initialize the bidi iterator.
838 (display_string): If we need to ignore text properties of
839 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
840 original value of -1 will not work with bidi.)
841 (compute_display_string_pos): First arg is now struct
842 `text_pos *'; all callers changed. Support display properties on
843 Lisp strings.
844 (compute_display_string_end): Support display properties on Lisp
845 strings.
846 (init_iterator, reseat_1, reseat_to_string): Initialize the
847 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
848 when iterating on a string not from display properties).
849 (compute_display_string_pos, compute_display_string_end):
850 Fix calculation of the object to scan. Fixes an error when using
851 arrow keys.
852 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
853 base_level_stop; instead, set base_level_stop to BEGV.
854 Fixes crashes in vertical-motion.
855 (next_element_from_buffer): Improve commentary for when
856 the iterator is before prev_stop.
857 (init_iterator): Initialize bidi_p from the default value of
858 bidi-display-reordering, not from buffer-local value. Use the
859 buffer-local value only if initializing for buffer iteration.
860 (handle_invisible_prop): Support invisible properties on strings
861 that are being bidi-reordered.
862 (set_iterator_to_next): Support bidi reordering of C strings and
863 Lisp strings.
864 (next_element_from_string): Support bidi reordering of Lisp
865 strings.
866 (handle_stop_backwards): Support Lisp strings as well.
867 (display_string): Support display of R2L glyph rows.
868 Use IT_STRING_CHARPOS when displaying from a Lisp string.
869 (init_iterator): Don't initialize it->bidi_p for strings
870 here.
871 (reseat_to_string): Initialize it->bidi_p for strings here.
872 (next_element_from_string, next_element_from_c_string)
873 (next_element_from_buffer): Add xassert's for correspondence
874 between IT's object being iterated and it->bidi_it.string
875 structure.
876 (face_before_or_after_it_pos): Support bidi iteration.
877 (next_element_from_c_string): Handle the case of the first string
878 character that is not the first one in the visual order.
879 (get_visually_first_element): New function, refactored from common
880 parts of next_element_from_buffer, next_element_from_string, and
881 next_element_from_c_string.
882 (tool_bar_lines_needed, redisplay_tool_bar)
883 (display_menu_bar): Force left-to-right direction. Add a FIXME
884 comment for making that be controlled by a user option.
885 (push_it, pop_it): Save and restore the state of the
886 bidi iterator. Save and restore the bidi_p flag.
887 (pop_it): Iterate out of display property for string iteration as
888 well.
889 (iterate_out_of_display_property): Support iteration over strings.

943 motion in bidi-reordered lines.
944 (move_it_in_display_line_to): Record prev_method and prev_pos
945 immediately before the call to set_iterator_to_next. Fixes cursor

1328 Remove unportable assumption about struct layout (Bug#8884).
1329 * alloc.c (mark_buffer):
1330 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
1331 (clone_per_buffer_values): Don't assume that
1332 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
1333 This isn't true in general, and it's particularly not true
1334 if Emacs is configured with --with-wide-int.
1335 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
1336 New macros, used in the buffer.c change.

1368 Add comment.
1369
1370 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
1371
1372 Random fixes. E.g., (random) never returned negative values.
1373 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
1374 subseconds part to the entropy, as that's a bit more random.
1375 Prefer signed to unsigned, since the signedness doesn't matter and
1376 in general we prefer signed. When given a limit, use a
1377 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
1378 latter isn't right if USE_2_TAGS_FOR_INTS.
1379 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
1380 not 0..VALMASK. Don't discard "excess" bits that random () returns.

1389
1390 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
1391
1392 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
1393 This is more efficient than Ffile_directory_p and avoids a minor race.
1394
1395 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
1396
1397 * buffer.c (Foverlay_put): Say what the return value is
1398 (bug#7835).
1399

1416
1417 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
1418 (syms_of_gnutls): Remove duplicate DEFSYM for
1419 Qgnutls_bootprop_verify_hostname_error, an error for
1420 Qgnutls_bootprop_verify_error (which is no longer used).
1421
1422 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
1423 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
1424 Also (re)move comments that are misplaced or no longer relevant.
1425
1426 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
1427

1449 leave any prefix arg for the up event (Bug#1586).
1450
1451 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
1452

1480 (Fcopy_keymap): Handle embedded parents.
1481 (Fcommand_remapping, define_as_prefix): Simplify.

1506 (emacs_settings_set_property, emacs_settings_class_init)
1507 (emacs_settings_init, gsettings_obj): Remove.
1508 (something_changedCB): New function for HAVE_GSETTINGS.

1510 with value as argument.
1511 (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling

1524
1525 * eval.c (struct backtrace): Simplify and port the data structure.
1526 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
1527 signed bit field, as this assumption is not portable and it makes
1528 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
1529 "char debug_on_exit : 1" as this is not portable either; instead,
1530 use the portable "unsigned int debug_on_exit : 1". Remove unused
1531 member evalargs. Remove obsolete comments about cc bombing out.
1532
1533 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

1572
1573 * buffer.c (Qclone_number): Declare static and DEFSYM it.
1574 (sort_overlays, overlay_strings): When an overlay's clone number
1575 matches the window's clone number process the overlay even if
1576 the overlay's window property doesn't match the current window.
1577
1578 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.
1579 (Fwindow_hchild): Rename to Fwindow_left_child.

1721 (read1): Check for integer overflow in radices, and in
1722 read-circle numbers.
1723 (read_escape): Avoid int overflow.
1724 (Fload, openp, read_buffer_size, read1)
1725 (substitute_object_recurse, read_vector, read_list, map_obarray):
1726 Use ptrdiff_t, not int, for sizes.
1727 (read1): Use EMACS_INT, not int, for sizes.
1728 Check for size overflow.
1729
1730 * image.c (cache_image): Check for size arithmetic overflow.
1731
1732 * lread.c: Integer overflow issues.

1734 (prev_saved_doc_string_size, prev_saved_doc_string_length):
1735 Now ptrdiff_t, not int.
1736 (read1): Don't assume doc string length fits in int. Check for
1737 out-of-range doc string lengths.

1739 (read_escape): Check for hex character overflow.
1740
1741 2011-06-22 Leo Liu <sdl.web@gmail.com>
1742
1743 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
1744 Move to minibuffer.el.
1745
1746 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
1747
1748 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
1749 The following patches are for when GLYPH_DEBUG && !XASSERT.
1750 * dispextern.h (trace_redisplay_p, dump_glyph_string):
1751 * dispnew.c (flush_stdout):
1752 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
1753 Mark as externally visible.
1754 * dispnew.c (check_window_matrix_pointers): Now static.
1755 * dispnew.c (window_to_frame_vpos):
1756 * xfns.c (unwind_create_frame):
1757 * xterm.c (x_check_font): Remove unused local.
1758 * scroll.c (CHECK_BOUNDS):
1759 * xfaces.c (cache_fache): Rename local to avoid shadowing.
1760 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
1761 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
1762 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
1763 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
1764 Now static.
1765 (debug_method_add): Use va_list and vsprintf rather than relying
1766 on undefined behavior with wrong number of arguments.
1767 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
1768 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
1769 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
1770 since we're not interested in debugging glyphs with old libraries.
1771 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
1772 GCC 4.6.0's static checking.
1773
1774 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
1775

1787 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
1788 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
1789 (.bitmaps_last):
1790 * xfaces.c (load_pixmap):
1791 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
1792 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
1793 (.bitmaps_last, struct x_output.icon_bitmap):
1794 Use ptrdiff_t, not int, for bitmap indexes.
1795 (x_allocate_bitmap_record): Check for size overflow.
1796 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
1797
1798 Use ptrdiff_t, not int, for overlay counts.
1799 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
1800 * editfns.c (overlays_around, get_pos_property):
1801 * textprop.c (get_char_property_and_overlay):
1802 * xdisp.c (next_overlay_change, note_mouse_highlight):
1803 * xfaces.c (face_at_buffer_position):
1804 * buffer.c (OVERLAY_COUNT_MAX): New macro.
1805 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
1806 (Fnext_overlay_change, Fprevious_overlay_change)
1807 (mouse_face_overlay_overlaps, Foverlays_in):
1808 Use ptrdiff_t, not int, for sizes.
1809 (overlays_at, overlays_in): Check for size-calculation overflow.
1810
1811 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
1812
1813 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
1814 (x_session_initialize): Do not assume string length fits in int.
1815
1816 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
1817 This is unlikely, but can occur if DPI is outlandish.
1818
1819 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
1820 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
1821
1822 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
1823 * xrdb.c (magic_file_p, search_magic_path):
1824 Omit last arg SUFFIX; it was always 0. All callers changed.
1825 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
1826
1827 * xfont.c (xfont_match): Avoid need for strlen.
1828
1829 * xfns.c: Don't assume strlen fits in int.
1830 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
1831
1832 * xdisp.c (message_log_check_duplicate): Return intmax_t,
1833 not unsigned long, as we prefer signed integers. All callers changed.
1834 Detect integer overflow in repeat count.
1835 (message_dolog): Don't assume print length fits in 39 bytes.
1836 (display_mode_element): Don't assume strlen fits in int.
1837
1838 * termcap.c: Don't assume sizes fit in int and never overflow.
1839 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
1840 (gobble_line): Check for size-calculation overflow.
1841
1842 * minibuf.c (Fread_buffer):
1843 * lread.c (intern, intern_c_string):
1844 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
1845 Don't assume string length fits in int.
1846
1847 * keyboard.c (parse_tool_bar_item):
1848 * gtkutil.c (style_changed_cb): Avoid need for strlen.
1849

1852 Use ptrdiff_t, not int.
1853 (font_intern_prop): Don't assume string length fits in int.
1854 Don't assume integer property fits in fixnum.
1855 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
1856
1857 * filelock.c: Fix some buffer overrun and integer overflow issues.
1858 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
1859 Reformulate so as not to need the command string.
1860 Invoke gzip -cd rather than gunzip, as it's more portable.
1861 (lock_info_type, lock_file_1, lock_file):
1862 Don't assume pid_t and time_t fit in unsigned long.
1863 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
1864 (current_lock_owner): Prefer signed type for sizes.
1865 Use memcpy, not strncpy, where memcpy is what is really wanted.
1866 Don't assume (via atoi) that time_t and pid_t fit in int.
1867 Check for time_t and/or pid_t out of range, e.g., via a network share.
1868 Don't alloca where an auto var works fine.
1869
1870 * fileio.c: Fix some integer overflow issues.
1871 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
1872 Don't assume string length fits in int.
1873 (directory_file_name): Don't assume string length fits in long.
1874 (make_temp_name): Don't assume pid fits in int, or that its print
1875 length is less than 20.
1876
1877 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
1878
1879 * coding.c (make_subsidiaries): Don't assume string length fits in int.
1880
1881 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
1882
1883 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
1884 We prefer signed integers, even for size calculations.
1885
1886 * emacs.c: Don't assume string length fits in 'int'.
1887 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
1888 (main): Don't invoke strlen when not needed.
1889
1890 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
1891 (XD_DEBUG_MESSAGE): Don't waste a byte.
1892
1893 * callproc.c (getenv_internal_1, getenv_internal)
1894 (Fgetenv_internal):
1895 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
1896
1897 * lread.c (invalid_syntax): Omit length argument.
1898 All uses changed. This doesn't fix a bug, but it simplifies the
1899 code away from its former Hollerith-constant appearance, and it's
1900 one less 'int' to worry about when looking at integer-overflow issues.
1901 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
1902
1903 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
1904 This didn't break anything, but it didn't help either.
1905 It's confusing to put a bogus integer in a place where the actual
1906 value does not matter.
1907 (LIST_END_P): Remove unused macro and its bogus comment.
1908 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
1909
1910 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
1911 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
1912 implementation.
1913 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
1914 We prefer signed types, and the value cannot exceed the EMACS_INT
1915 range anyway (because otherwise the length would not be representable).
1916 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
1917 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
1918 This avoids a GCC warning when WIDE_EMACS_INT.
1919
1920 * indent.c (sane_tab_width): New function.
1921 (current_column, scan_for_column, Findent_to, position_indentation)
1922 (compute_motion): Use it. This is just for clarity.
1923 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
1924
1925 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
1926
1927 * lisp.h (lint_assume): New macro.
1928 * composite.c (composition_gstring_put_cache):
1929 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
1930
1931 * editfns.c, insdel.c:
1932 Omit unnecessary forward decls, to simplify future changes.
1933
1934 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
1935
1936 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
1937
1938 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
1939 Use much-faster test for byte-length change.
1940 Don't assume string byte-length fits in 'int'.
1941 Check that character arg fits in 'int'.
1942 (mapcar1): Declare byte as byte, for clarity.
1943
1944 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
1945
1946 * fns.c (concat): Catch string overflow earlier.
1947 Do not rely on integer wraparound.
1948
1949 * dispextern.h (struct it.overlay_strings_charpos)
1950 (struct it.selective): Now EMACS_INT, not int.
1951 * xdisp.c (forward_to_next_line_start)
1952 (back_to_previous_visible_line_start)
1953 (reseat_at_next_visible_line_start, next_element_from_buffer):
1954 Don't arbitrarily truncate the value of 'selective' to int.
1955
1956 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
1957
1958 * composite.c: Don't truncate sizes to 'int'.
1959 (composition_gstring_p, composition_reseat_it)
1960 (composition_adjust_point): Use EMACS_INT, not int.
1961 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
1962 not EMACS_UINT, for indexes.
1963
1964 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
1965
1966 * buffer.c: Include <verify.h>.
1967 (struct sortvec.priority, struct sortstr.priority):
1968 Now EMACS_INT, not int.
1969 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
1970 (struct sortstr.size, record_overlay_string)
1971 (struct sortstrlist.size, struct sortlist.used):
1972 Don't truncate size to int.
1973 (record_overlay_string): Check for size-calculation overflow.
1974 (init_buffer_once): Check at compile-time, not run-time.
1975
1976 2011-06-22 Jim Meyering <meyering@redhat.com>
1977
1978 Don't leak an XBM-image-sized buffer
1979 * image.c (xbm_load): Free the image buffer after using it.
1980
1981 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
1982
1983 Port to Sun C.
1984 * composite.c (find_automatic_composition): Omit needless 'return 0;'
1985 that Sun C diagnosed.
1986 * fns.c (secure_hash): Fix pointer signedness issue.
1987 * intervals.c (static_offset_intervals): New function.
1988 (offset_intervals): Use it.
1989
1990 2011-06-21 Leo Liu <sdl.web@gmail.com>
1991
1992 * deps.mk (fns.o):
1993 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
1994 sha512.h.
1995
1996 * fns.c (secure_hash): Rename from crypto_hash_function and change
1997 the first arg to accept symbols.
1998 (Fsecure_hash): New primitive.
1999 (syms_of_fns): New symbols.
2000
2001 2011-06-20 Deniz Dogan <deniz@dogan.se>
2002
2003 * process.c (Fset_process_buffer): Clarify return value in
2004 docstring.
2005
2006 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
2007
2008 * dispnew.c (add_window_display_history): Use BVAR.
2009
2010 * xdisp.c (debug_method_add): Use BVAR.
2011 (check_window_end, dump_glyph_matrix, dump_glyph)
2012 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
2013
2014 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
2015 Likewise.
2016
2017 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
2018 check till after the cache is created in init_frame_faces.
2019
2020 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
2021
2022 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
2023
2024 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
2025
2026 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
2027 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
2028 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
2029
2030 Improve buffer-overflow checking (Bug#8873).
2031 * fileio.c (Finsert_file_contents):
2032 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
2033 Remove the old (too-loose) buffer overflow checks.
2034 They weren't needed, since make_gap checks for buffer overflow.
2035 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
2036 The old code merely checked for Emacs fixnum overflow, and relied
2037 on undefined (wraparound) behavior. The new code avoids undefined
2038 behavior, and also checks for ptrdiff_t and/or size_t overflow.
2039
2040 * editfns.c (Finsert_char): Don't dump core with very negative counts.
2041 Tune. Don't use wider integers than needed. Don't use alloca.
2042 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
2043
2044 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
2045
2046 * insdel.c, lisp.h (buffer_overflow): New function.
2047 (insert_from_buffer_1, replace_range, replace_range_2):
2048 * insdel.c (make_gap_larger):
2049 * editfns.c (Finsert_char):
2050 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
2051
2052 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
2053
2054 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
2055
2056 Integer overflow and signedness fixes (Bug#8873).
2057
2058 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
2059 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
2060
2061 * fileio.c: Don't assume EMACS_INT fits in off_t.
2062 (emacs_lseek): New static function.
2063 (Finsert_file_contents, Fwrite_region): Use it.
2064 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
2065
2066 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
2067
2068 * fns.c: Don't overflow int when computing a list length.
2069 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
2070 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
2071 truncation on 64-bit hosts. Check for QUIT every
2072 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
2073 faster and is responsive enough.
2074 (Flength): Report an error instead of overflowing an integer.
2075 (Fsafe_length): Return a float if the value is not representable
2076 as a fixnum. This shouldn't happen except in contrived situations.
2077 (Fnthcdr, Fsort): Don't assume list length fits in int.
2078 (Fcopy_sequence): Don't assume vector length fits in int.
2079
2080 * alloc.c: Check that resized vectors' lengths fit in fixnums.
2081 (header_size, word_size): New constants.
2082 (allocate_vectorlike): Don't check size overflow here.
2083 (allocate_vector): Check it here instead, since this is the only
2084 caller of allocate_vectorlike that could cause overflow.
2085 Check that the new vector's length is representable as a fixnum.
2086
2087 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
2088 The previous code was bogus. For example, next_almost_prime (32)
2089 returned 39, which is undesirable as it is a multiple of 3; and
2090 next_almost_prime (24) returned 25, which is a multiple of 5 so
2091 why was the code bothering to check for multiples of 7?
2092
2093 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
2094
2095 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
2096
2097 Variadic C functions now count arguments with ptrdiff_t.
2098 This partly undoes my 2011-03-30 change, which replaced int with size_t.
2099 Back then I didn't know that the Emacs coding style prefers signed int.
2100 Also, in the meantime I found a few more instances where arguments
2101 were being counted with int, which may truncate counts on 64-bit
2102 machines, or EMACS_INT, which may be unnecessarily wide.
2103 * lisp.h (struct Lisp_Subr.function.aMANY)
2104 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
2105 Arg counts are now ptrdiff_t, not size_t.
2106 All variadic functions and their callers changed accordingly.
2107 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
2108 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
2109 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
2110 * callint.c (Fcall_interactively): Check arg count for overflow,
2111 to avoid potential buffer overrun. Use signed char, not 'int',
2112 for 'varies' array, so that we needn't bother to check its size
2113 calculation for overflow.
2114 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
2115 * eval.c (apply_lambda):
2116 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
2117 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
2118 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
2119
2120 * callint.c (Fcall_interactively): Don't use index var as event count.
2121
2122 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
2123 * mem-limits.h (SIZE): Remove; no longer used.
2124
2125 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
2126
2127 Remove unnecessary casts.
2128 * xterm.c (x_term_init):
2129 * xfns.c (x_set_border_pixel):
2130 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
2131 These aren't needed now that we assume ANSI C.
2132
2133 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
2134 It's more likely to cause problems (due to unsigned overflow)
2135 than to cure them.
2136
2137 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
2138
2139 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
2140
2141 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
2142
2143 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
2144
2145 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
2146
2147 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
2148
2149 GLYPH_CODE_FACE returns EMACS_INT, not int.
2150 * dispextern.h (merge_faces):
2151 * xfaces.c (merge_faces):
2152 * xdisp.c (get_next_display_element, next_element_from_display_vector):
2153 Don't assume EMACS_INT fits in int.
2154
2155 * character.h (CHAR_VALID_P): Remove unused parameter.
2156 * fontset.c, lisp.h, xdisp.c: All uses changed.
2157
2158 * editfns.c (Ftranslate_region_internal): Omit redundant test.
2159
2160 * fns.c (concat): Minor tuning based on overflow analysis.
2161 This doesn't fix any bugs. Use int to hold character, instead
2162 of constantly refetching from Emacs object. Use XFASTINT, not
2163 XINT, for value known to be a character. Don't bother comparing
2164 a single byte to 0400, as it's always less.
2165
2166 * floatfns.c (Fexpt):
2167 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
2168
2169 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
2170 for characters.
2171
2172 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
2173
2174 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
2175 Without this fix, on a 64-bit host (aset S 0 4294967386) would
2176 incorrectly succeed when S was a string, because 4294967386 was
2177 truncated before it was used.
2178
2179 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
2180 Otherwise, an out-of-range integer could cause undefined behavior
2181 on a 64-bit host.
2182
2183 * composite.c: Use int, not EMACS_INT, for characters.
2184 (fill_gstring_body, composition_compute_stop_pos): Use int, not
2185 EMACS_INT, for values that are known to be in character range.
2186 This doesn't fix any bugs but is the usual style inside Emacs and
2187 may generate better code on 32-bit machines.
2188
2189 Make sure a 64-bit char is never passed to ENCODE_CHAR.
2190 This is for reasons similar to the recent CHAR_STRING fix.
2191 * charset.c (Fencode_char): Check that character arg is actually
2192 a character. Pass an int to ENCODE_CHAR.
2193 * charset.h (ENCODE_CHAR): Verify that the character argument is no
2194 wider than 'int', as a compile-time check to prevent future regressions
2195 in this area.
2196
2197 * character.c (char_string): Remove unnecessary casts.
2198
2199 Make sure a 64-bit char is never passed to CHAR_STRING.
2200 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
2201 by silently ignoring the top 32 bits, allowing some values
2202 that were far too large to be valid characters.
2203 * character.h: Include <verify.h>.
2204 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
2205 arguments are no wider than unsigned, as a compile-time check
2206 to prevent future regressions in this area.
2207 * data.c (Faset):
2208 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
2209 (Fsubst_char_in_region):
2210 * fns.c (concat):
2211 * xdisp.c (decode_mode_spec_coding):
2212 Adjust to CHAR_STRING's new requirement.
2213 * editfns.c (Finsert_char, Fsubst_char_in_region):
2214 * fns.c (concat): Check that character args are actually
2215 characters. Without this test, these functions did the wrong
2216 thing with wildly out-of-range values on 64-bit hosts.
2217
2218 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
2219 These casts should not be needed on 32-bit hosts, either.
2220 * keyboard.c (read_char):
2221 * lread.c (Fload): Remove casts to unsigned.
2222
2223 * lisp.h (UNSIGNED_CMP): New macro.
2224 This fixes comparison bugs on 64-bit hosts.
2225 (ASCII_CHAR_P): Use it.
2226 * casefiddle.c (casify_object):
2227 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
2228 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
2229 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
2230 * dispextern.h (FACE_FROM_ID):
2231 * keyboard.c (read_char): Use UNSIGNED_CMP.
2232
2233 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
2234 not to EMACS_INT, to avoid GCC warning.
2235
2236 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
2237
2238 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
2239 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
2240 isn't needed on 32-bit machines.
2241
2242 * buffer.c (Fgenerate_new_buffer_name):
2243 Use EMACS_INT for count, not int.
2244 (advance_to_char_boundary): Return EMACS_INT, not int.
2245
2246 * data.c (Qcompiled_function): Now static.
2247
2248 * window.c (window_body_lines): Now static.
2249
2250 * image.c (gif_load): Rename local to avoid shadowing.
2251
2252 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
2253 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
2254 * alloc.c (make_save_value): Integer argument is now of type
2255 ptrdiff_t, not int.
2256 (mark_object): Use ptrdiff_t, not int.
2257 * lisp.h (pD): New macro.
2258 * print.c (print_object): Use it.
2259
2260 * alloc.c: Use EMACS_INT, not int, to count objects.
2261 (total_conses, total_markers, total_symbols, total_vector_size)
2262 (total_free_conses, total_free_markers, total_free_symbols)
2263 (total_free_floats, total_floats, total_free_intervals)
2264 (total_intervals, total_strings, total_free_strings):
2265 Now EMACS_INT, not int. All uses changed.
2266 (Fgarbage_collect): Compute overall total using a double, so that
2267 integer overflow is less likely to be a problem. Check for overflow
2268 when converting back to an integer.
2269 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
2270 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
2271 These were 'int' variables that could overflow on 64-bit hosts;
2272 they were never used, so remove them instead of repairing them.
2273 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
2274 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
2275 Previously, this ceilinged at INT_MAX, but that doesn't work on
2276 64-bit machines.
2277 (allocate_pseudovector): Don't use EMACS_INT when int would do.
2278
2279 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
2280 (allocate_vectorlike): Check for ptrdiff_t overflow.
2281 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
2282 when a (possibly-narrower) signed value would do just as well.
2283 We prefer using signed arithmetic, to avoid comparison confusion.
2284
2285 * alloc.c: Catch some string size overflows that we were missing.
2286 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
2287 for convenience in STRING_BYTES_MAX.
2288 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
2289 The definition here is exact; the one in lisp.h was approximate.
2290 (allocate_string_data): Check for string overflow. This catches
2291 some instances we weren't catching before. Also, it catches
2292 size_t overflow on (unusual) hosts where SIZE_MAX <= min
2293 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
2294 and ptrdiff_t and EMACS_INT are both 64 bits.
2295
2296 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
2297 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
2298 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
2299
2300 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
2301
2302 * alloc.c (Fmake_string): Check for out-of-range init.
2303
2304 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
2305
2306 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
2307
2308 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
2309
2310 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
2311 xg_get_default_scrollbar_width.
2312
2313 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
2314 (int_gtk_range_get_value): Move to the scroll bar part of the file.
2315 (style_changed_cb): Call update_theme_scrollbar_width and call

2317 all frames (Bug#8505).
2318 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
2319 Call gtk_window_set_resizable if HAVE_GTK3.

2323 (update_theme_scrollbar_width): New function.
2324 (xg_get_default_scrollbar_width): Move code to
2325 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
2326 (xg_initialize): Call update_theme_scrollbar_width.
2327
2328 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
2329
2330 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
2331
2332 2011-06-12 Martin Rudalics <rudalics@gmx.at>
2333
2334 * frame.c (make_frame): Call other_buffer_safely instead of
2335 other_buffer.
2336
2337 * window.c (temp_output_buffer_show): Call display_buffer with
2338 second argument Vtemp_buffer_show_specifiers and reset latter
2339 immediately after the call.
2340 (Vtemp_buffer_show_specifiers): New variable.
2341 (auto_window_vscroll_p, next_screen_context_lines)
2342 (Vscroll_preserve_screen_position): Remove leading asterisks from
2343 doc-strings.
2344

2412 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
2413 calls to replace_buffer_in_windows and

2806 is separated from the issue of spare memory.
2807

2866 display string.
2867 (bidi_paragraph_init, bidi_resolve_explicit_1)
2868 (bidi_level_of_next_char): Call bidi_fetch_char and

2875 instead of using explicit *_CHAR codes.
2876 (bidi_resolve_explicit, bidi_resolve_weak):
2877 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
2878 bidirectional text is supported only in multibyte buffers.

2887 were just reseat()'ed to a new position.
2888
2889 * xdisp.c (set_cursor_from_row): Set start and stop points
2890 according to the row's direction when priming the loop that looks

2893 (display_prop_intangible_p): Reimplement to call
2894 handle_display_spec instead of single_display_spec_intangible_p.
2895 Accept 3 additional arguments needed by handle_display_spec.
2896 This fixes incorrect cursor motion across display property with complex
2897 values: lists, `(when COND...)' forms, etc.
2898 (single_display_spec_string_p): Support property values that are
2899 lists with the argument STRING its top-level element.
2900 (display_prop_string_p): Fix the condition for processing a

2903 last portion of handle_display_prop.
2904 (compute_display_string_pos): Accept additional argument
2905 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
2906 value of a `display' property is a "replacing spec".
2907 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
2908 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

2936 All callers changed. (Bug#8762)
2937
2938 * gnutls.c: Use Emacs's memory allocators.
2939 Without this change, the gnutls library would invoke malloc etc.
2940 directly, which causes problems on non-SYNC_INPUT hosts, and which
2941 runs afoul of improving memory_full behavior. (Bug#8761)
2942 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
2943 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
2944 xfree instead of the default malloc, realloc, free.
2945 (Fgnutls_boot): No need to check for memory allocation failure,
2946 since xmalloc does that for us.
2947
2948 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

2966 * lisp.h (struct Lisp_Hash_Table):
2967 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
2968 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
2969 for hashes and hash indexes, instead of 'unsigned' and 'int'.
2970 * alloc.c (allocate_vectorlike):
2971 Check for overflow in vector size calculations.
2972 * ccl.c (ccl_driver):
2973 Check for overflow when converting EMACS_INT to int.
2974 * fns.c, image.c: Remove unnecessary static decls that would otherwise
2975 need to be updated by these changes.

2977 Check for integer overflow with large hash tables.
2978 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):

2980 (SXHASH_REDUCE): New macro.
2981 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
2982 Use it instead of discarding useful hash info with large hash values.
2983 (sxhash_float): New function.
2984 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
2985 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
2986 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
2987 Rewrite to use FIXNUM_BITS, as this simplifies things.
2988 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
2989 Adjust signatures to match updated version of code.
2990 (consing_since_gc): Now EMACS_INT, since a single hash table can
2991 use more than INT_MAX bytes.

3037
3038 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3039
3040 Make it possible to run ./temacs.
3041
3042 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
3043 syms_of_callproc does the same thing. Remove test for
3044 "initialized", do it in the caller.
3045 * emacs.c (main): Avoid calling set_initial_environment when dumping.
3046
3047 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>

3052 (Qmetadata): New var.
3053 * data.c (Qbuffer): Don't make it static.
3054 (syms_of_data): Use DEFSYM.
3055
3056 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3057

3059 (CCL_CODE_MIN): New macro.
3060
3061 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
3062
3063 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
3064
3065 * eval.c (Qdebug): Now static.
3066 * lisp.h (Qdebug): Remove decl. This reverts a part of the
3067 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
3068 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.

3072 * image.c: Various fixes to ImageMagick code comments.
3073 (Fimagemagick_types): Doc fix.
3074
3075 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
3076

3078
3079 * xselect.c (converted_selections, conversion_fail_tag): Now static.
3080
3081 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
3082 (x_clipboard_manager_save_all): Move extern decl to ...
3083 * xterm.h: ... here, so that it can be checked for consistency.
3084
3085 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3086
3087 * xselect.c (x_clipboard_manager_save_frame)

3100
3101 2011-05-28 Jim Meyering <meyering@redhat.com>
3102
3103 Avoid a sign-extension bug in crypto_hash_function.
3104 * fns.c (to_uchar): Define.
3105 (crypto_hash_function): Use it to convert some newly-signed
3106 variables to unsigned, to avoid sign-extension bugs. For example,
3107 without this change, (md5 "truc") would evaluate to
3108 45723a2aff78ff4fff7fff1114760e62 rather than the expected
3109 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
3110 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
3111
3112 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3113
3114 Integer overflow fixes.
3115
3116 * dbusbind.c: Serial number integer overflow fixes.
3117 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
3118 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
3119 to hold a serial number that is too large for a fixnum.
3120 (Fdbus_method_return_internal, Fdbus_method_error_internal):
3121 Check for serial numbers out of range. Decode any serial number
3122 that was so large that it became a float. (Bug#8722)
3123
3124 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
3125 (Fdbus_call_method, Fdbus_call_method_asynchronously):
3126 Use XFASTINT rather than XUINT when numbers are nonnegative.
3127 (xd_append_arg, Fdbus_method_return_internal):
3128 (Fdbus_method_error_internal): Likewise. Also, for unsigned
3129 arguments, check that Lisp number is nonnegative, rather than
3130 silently wrapping negative numbers around. (Bug#8722)
3131 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
3132 (Bug#8722)
3133
3134 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
3135
3136 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
3137
3138 ccl: add integer overflow checks
3139 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
3140 (IN_INT_RANGE): New macros.
3141 (ccl_driver): Use them to check for integer overflow when
3142 decoding a CCL program. Many of the new checks are whether XINT (x)
3143 fits in int; it doesn't always, on 64-bit hosts. The new version
3144 doesn't catch all possible integer overflows, but it's an
3145 improvement. (Bug#8719)
3146
3147 * alloc.c (make_event_array): Use XINT, not XUINT.
3148 There's no need for unsigned here.
3149
3150 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
3151 This follows up to the 2011-05-06 change that substituted uintptr_t
3152 for EMACS_INT. This case wasn't caught back then.
3153
3154 Rework Fformat to avoid integer overflow issues.
3155 * editfns.c: Include <float.h> unconditionally, as it's everywhere
3156 now (part of C89). Include <verify.h>.
3157 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
3158 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
3159 (Fformat): Avoid the prepass trying to compute sizes; it was only
3160 approximate and thus did not catch overflow reliably. Instead, walk
3161 through the format just once, formatting and computing sizes as we go,
3162 checking for integer overflow at every step, and allocating a larger
3163 buffer as needed. Keep track separately whether the format is
3164 multibyte. Keep only the most-recently calculated precision, rather
3165 than them all. Record whether each argument has been converted to
3166 string. Use EMACS_INT, not int, for byte and char and arg counts.
3167 Support field widths and precisions larger than INT_MAX. Avoid
3168 sprintf's undefined behavior with conversion specifications such as %#d
3169 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
3170 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
3171 formatting out-of-range floating point numbers with int
3172 formats. (Bug#8668)
3173
3174 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
3175
3176 * data.c: Avoid integer truncation in expressions involving floats.
3177 * data.c: Include <intprops.h>.
3178 (arith_driver): When there's an integer overflow in an expression
3179 involving floating point, convert the integers to floating point
3180 so that the resulting value does not suffer from catastrophic
3181 integer truncation. For example, on a 64-bit host (* 4
3182 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
3183 Do not rely on undefined behavior after integer overflow.
3184
3185 merge count_size_as_multibyte, parse_str_to_multibyte
3186 * character.c, character.h (count_size_as_multibyte):
3187 Rename from parse_str_to_multibyte; all uses changed.
3188 Check for integer overflow.
3189 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
3190 since it's now a duplicate of the other. This is more of
3191 a character than a buffer op, so better that it's in character.c.
3192 * fns.c, print.c: Adjust to above changes.
3193
3194 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
3195
3196 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
3197
3198 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3199
3200 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3201 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
3202 (x_clipboard_manager_save): Now static.
3203 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
3204
3205 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3206 (crypto_hash_function): Now static.
3207 Fix pointer signedness problems. Avoid unnecessary initializations.
3208
3209 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
3210
3211 * termhooks.h (Vselection_alist): Make it terminal-local.
3212
3213 * terminal.c (create_terminal): Initialize it.
3214
3215 * xselect.c: Support for clipboard managers.
3216 (Vselection_alist): Move to termhooks.h as terminal-local var.
3217 (LOCAL_SELECTION): New macro.
3218 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
3219 (symbol_to_x_atom): Remove gratuitous arg.
3220 (x_handle_selection_request, lisp_data_to_selection_data)
3221 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
3222 (x_own_selection, x_get_local_selection, x_convert_selection):
3223 New arg, specifying work frame. Use terminal-local Vselection_alist.
3224 (some_frame_on_display): Delete unused function.
3225 (Fx_own_selection_internal, Fx_get_selection_internal)
3226 (Fx_disown_selection_internal, Fx_selection_owner_p)
3227 (Fx_selection_exists_p): New optional frame arg.
3228 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
3229 (x_handle_selection_clear): Don't treat other terminals with the
3230 same keyboard specially. Use the terminal-local Vselection_alist.
3231 (x_clear_frame_selections): Use Frun_hook_with_args.
3232
3233 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
3234
3235 * xterm.h: Add support for those atoms.
3236
3237 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
3238
3239 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
3240 (converted_selections, conversion_fail_tag): New global variables.
3241 (x_selection_request_lisp_error): Free the above.
3242 (x_get_local_selection): Remove unnecessary code.
3243 (x_reply_selection_request): Args changed; handle arbitrary array
3244 of converted selections stored in converted_selections.
3245 Separate the XChangeProperty and SelectionNotify steps.
3246 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
3247 (x_convert_selection): New function.
3248 (x_handle_selection_event): Simplify.
3249 (x_get_foreign_selection): Don't ignore incoming requests while
3250 waiting for an answer; this will fail when we implement
3251 SAVE_TARGETS, and seems unnecessary anyway.
3252 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
3253 (Vx_sent_selection_functions): Doc fix.
3254
3255 2011-05-26 Leo Liu <sdl.web@gmail.com>

3294 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
3295 Remove macros that are defined and never used.
3296 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).

3320 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
3321 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
3322 and add some more files.

3325
3326 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
3327 report_file_error introduced by the change from 2011-05-07.

3330
3331 * systime.h (Time): Define only if emacs is defined.

3371 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
3372
3373 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
3374
3375 Fix some integer overflow issues, such as string length overflow.
3376
3377 * insdel.c (count_size_as_multibyte): Check for string overflow.
3378
3379 * character.c (lisp_string_width): Check for string overflow.
3380 Use EMACS_INT, not int, for string indexes and lengths; in
3381 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
3382 the resulting string length overflows an EMACS_INT; instead,
3383 report a string overflow if no precision given. When checking for
3384 precision exhaustion, use a check that cannot possibly have
3385 integer overflow. (Bug#8675)
3386 * character.h (lisp_string_width): Adjust to new signature.
3387
3388 * alloc.c (string_overflow): New function.
3389 (Fmake_string): Use it. This doesn't change behavior, but saves
3390 a few bytes and will simplify future changes.
3391 * character.c (string_escape_byte8): Likewise.
3392 * lisp.h (string_overflow): New decl.
3393
3394 Fixups, following up to the user-interface timestamp change.
3395 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
3396 for UI timestamps, instead of unsigned long.
3397 * msdos.c (mouse_get_pos): Likewise.
3398 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
3399 * w32gui.h (Time): Define by including "systime.h" rather than by
3400 declaring it ourselves. (Bug#8664)
3401
3402 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
3403 * image.c (clear_image_cache): Likewise.
3404
3405 * term.c (term_mouse_position): Don't assume time_t wraparound.
3406
3407 Be more systematic about user-interface timestamps.
3408 Before, the code sometimes used 'Time', sometimes 'unsigned long',
3409 and sometimes 'EMACS_UINT', to represent these timestamps.
3410 This change causes it to use 'Time' uniformly, as that's what X uses.
3411 This makes the code easier to follow, and makes it easier to catch
3412 integer overflow bugs such as Bug#8664.
3413 * frame.c (Fmouse_position, Fmouse_pixel_position):
3414 Use Time, not unsigned long, for user-interface timestamps.
3415 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
3416 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
3417 * keyboard.h (last_event_timestamp): Likewise.
3418 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
3419 * menu.h (xmenu_show): Likewise.
3420 * term.c (term_mouse_position): Likewise.
3421 * termhooks.h (struct input_event.timestamp): Likewise.
3422 (struct terminal.mouse_position_hook): Likewise.
3423 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
3424 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
3425 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
3426 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
3427 what it was before.
3428 * menu.h, termhooks.h: Include "systime.h", for Time.
3429
3430 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
3431 Don't assume that the difference between two unsigned long values
3432 can fit into an integer. At this point, we know button_down_time
3433 <= event->timestamp, so the difference must be nonnegative, so
3434 there's no need to cast the result if double-click-time is
3435 nonnegative, as it should be; check that it's nonnegative, just in
3436 case. This bug is triggered when events are more than 2**31 ms
3437 apart (about 25 days). (Bug#8664)
3438
3439 * xselect.c (last_event_timestamp): Remove duplicate decl.
3440 (x_own_selection): Remove needless cast to unsigned long.
3441
3442 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
3443 that always fit in int. Use a sentinel instead of a counter, to
3444 avoid a temp and to allay GCC's concerns about possible int overflow.
3445 * frame.h (struct frame): Use int for menu_bar_items_used
3446 instead of EMACS_INT, since it always fits in int.
3447
3448 * menu.c (grow_menu_items): Check for int overflow.
3449
3450 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
3451
3452 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
3453 Before, the code was not consistent. These values cannot exceed
3454 2**31 - 1 so there's no need to make them unsigned.
3455 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
3456 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
3457 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
3458 as modifiers.
3459 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
3460
3461 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
3462 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
3463 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
3464 presumably because the widths might not match.
3465
3466 * window.c (size_window): Avoid needless test at loop start.
3467
3468 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
3469
3470 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
3471
3472 2011-05-12 Drew Adams <drew.adams@oracle.com>
3473
3474 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
3475
3476 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3477
3478 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
3479 `width' to `bar_area_x' and `bar_area_width', respectively.
3480 (x_scroll_run): Take account of fringe background extension.
3481
3482 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
3483 Rename local vars `left' and `width' to `bar_area_x' and
3484 `bar_area_width', respectively.
3485 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
3486 background extension.
3487
3488 2011-05-10 Jim Meyering <meyering@redhat.com>
3489
3490 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
3491
3492 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
3493
3494 * image.c (Finit_image_library): Return t for built-in image types,
3495 like pbm and xbm. (Bug#8640)
3496
3497 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
3498
3499 * w32menu.c (set_frame_menubar): Fix submenu allocation.
3500
3501 2011-05-07 Eli Zaretskii <eliz@gnu.org>
3502
3503 * w32console.c (Fset_screen_color): Doc fix.
3504 (Fget_screen_color): New function.
3505 (syms_of_ntterm): Defsubr it.
3506
3507 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
3508 unlink the temporary file if Fcall_process didn't create it in the
3509 first place.
3510 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
3511 child process will be redirected to a file specified with `:file'.
3512 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
3513 cue to call_process_cleanup not to close that handle.
3514
3515 2011-05-07 Ben Key <bkey76@gmail.com>
3516
3517 * makefile.w32-in: The bootstrap-temacs rule now makes use of
3518 one of two shell specific rules, either bootstrap-temacs-CMD or
3519 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
3520 to the previous implementation of the bootstrap-temacs rule.
3521 The bootstrap-temacs-CMD rule is similar to the previous
3522 implementation of the bootstrap-temacs rule except that it
3523 makes use of the ESC_CFLAGS variable instead of the CFLAGS
3524 variable.
3525
3526 These changes, along with some changes to nt/configure.bat,
3527 nt/gmake.defs, and nt/nmake.defs, are required to extend my
3528 earlier fix to add support for --cflags and --ldflags options
3529 that include quotes so that it works whether make uses cmd or
3530 sh as the shell.
3531
3532 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
3533
3534 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
3535 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
3536 is a constant.
3537 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
3538 a string. Handle both cases.
3539 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
3540 (Fdbus_register_method): Use Qinvalid_function.
3541
3542 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3543
3544 * makefile.w32-in: Update dependencies.
3545 (LISP_H): Add inttypes.h and stdin.h.
3546 (PROCESS_H): Add unistd.h.
3547
3548 2011-05-06 Eli Zaretskii <eliz@gnu.org>
3549
3550 * lread.c: Include limits.h (fixes the MS-Windows build broken by
3551 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
3552
3553 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
3554
3555 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
3556
3557 * term.c (vfatal): Remove stray call to va_end.
3558 It's not needed and the C Standard doesn't allow it here anyway.
3559
3560 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
3561 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
3562
3563 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
3564 bytes.
3565
3566 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
3567
3568 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3569
3570 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
3571
3572 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
3573
3574 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
3575
3576 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
3577 * charset.c (Fdefine_charset_internal): Don't initialize
3578 charset.code_space[15]. The value was garbage, on hosts with
3579 32-bit int (Bug#8600).
3580
3581 * lread.c (read_integer): Be more consistent with string-to-number.
3582 Use string_to_number to do the actual conversion; this avoids
3583 rounding errors and fixes some other screwups. Without this fix,
3584 for example, #x1fffffffffffffff was misread as -2305843009213693952.
3585 (digit_to_number): Move earlier, for benefit of read_integer.
3586 Return -1 if the digit is out of range for the base, -2 if it is
3587 not a digit in any supported base. (Bug#8602)
3588
3589 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
3590
3591 * dispnew.c (scrolling_window): Return 1 if we scrolled,
3592 to match comment at start of function. This also removes a
3593 GCC warning about overflow in a 32+64-bit port.
3594
3595 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
3596
3597 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
3598 Reported by Stefan Monnier in
3599 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
3600 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3601 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
3602
3603 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
3604 (EMACS_UINTPTR): Likewise, with uintptr_t.
3605
3606 * lisp.h: Prefer 64-bit EMACS_INT if available.
3607 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
3608 on 32-bit hosts that have 64-bit int, so that they can access
3609 large files.
3610 However, temporarily disable this change unless the temporary
3611 symbol WIDE_EMACS_INT is defined.
3612
3613 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
3614
3615 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
3616 This removes an assumption that EMACS_INT and long are the same
3617 width as pointers. The assumption is true for Emacs porting targets
3618 now, but we want to make other targets possible.
3619 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
3620 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
3621 In the rest of the code, change types of integers that hold casted
3622 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
3623 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
3624 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
3625 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
3626 No need to cast type when ORing.
3627 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
3628 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
3629 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
3630 assume EMACS_INT is the same width as char *.
3631 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
3632 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
3633 Remove no-longer-needed casts.
3634 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
3635 (xg_tool_bar_help_callback, xg_make_tool_item):
3636 Use EMACS_INTPTR to hold an integer
3637 that will be cast to void *; this can avoid a GCC warning
3638 if EMACS_INT is not the same width as void *.
3639 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
3640 * xdisp.c (display_echo_area_1, resize_mini_window_1):
3641 (current_message_1, set_message_1):
3642 Use a local to convert to proper width without a cast.
3643 * xmenu.c (dialog_selection_callback): Likewise.
3644
3645 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
3646 Also, don't assume VALBITS / RAND_BITS is less than 5,
3647 and don't rely on undefined behavior when shifting a 1 left into
3648 the sign bit.
3649 * lisp.h (get_random): Change signature to match.
3650
3651 * lread.c (hash_string): Use size_t, not int, for hash computation.
3652 Normally we prefer signed values; but hashing is special, because
3653 it's better to use unsigned division on hash table sizes so that
3654 the remainder is nonnegative. Also, size_t is the natural width
3655 for hashing into memory. The previous code used 'int', which doesn't
3656 retain enough info to hash well into very large tables.
3657 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
3658
3659 * dbusbind.c: Don't possibly lose pointer info when converting.
3660 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3661 Use XPNTR rather than XHASH, so that the high-order bits of
3662 the pointer aren't lost when converting through void *.
3663
3664 * eval.c (Fautoload): Don't double-shift a pointer.
3665
3666 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
3667
3668 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3669
3670 * gnutls.c (DEF_GNUTLS_FN):
3671 * image.c (DEF_IMGLIB_FN): Make function pointers static.
3672
3673 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
3674
3675 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
3676 marker. (Bug#8610)
3677
3678 2011-05-05 Eli Zaretskii <eliz@gnu.org>
3679
3680 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
3681 New version that can reserve upto 2GB of heap space.
3682
3683 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
3684
3685 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
3686
3687 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
3688
3689 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
3690 `gnutls_certificate_set_x509_key_file'.
3691
3692 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
3693
3694 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
3695 Update dependencies.
3696
3697 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3698
3699 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
3700 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
3701 Remove unused parameter `fildes'.
3702 * process.c (read_process_output, send_process): Don't pass it.
3703
3704 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3705
3706 Fix previous change: the library cache is defined in w32.c.
3707 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
3708 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
3709
3710 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3711
3712 Implement dynamic loading of GnuTLS on Windows.
3713
3714 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
3715 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
3716 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
3717 Declare.
3718
3719 * gnutls.c (Qgnutls_dll): Define.
3720 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
3721 (gnutls_*): Declare function pointers.
3722 (init_gnutls_functions): New function to initialize function pointers.
3723 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
3724 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
3725 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
3726 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
3727 (emacs_gnutls_write, emacs_gnutls_read)
3728 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
3729 (Fgnutls_available_p): New function.
3730 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
3731 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
3732 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
3733
3734 * image.c: Include w32.h.
3735 (Vimage_type_cache): Delete.
3736 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
3737 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
3738 (w32_delayed_load): Move to w32.c.
3739
3740 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
3741
3742 * w32.c (QCloaded_from, Vlibrary_cache): Define.
3743 (w32_delayed_load): Move from image.c. When loading a library, record
3744 its filename in the :loaded-from property of the library id.
3745 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
3746 Initialize and staticpro them.
3747 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
3748
3749 * process.c: Include lisp.h before w32.h, not after.
3750 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
3751 instead of gnutls_record_check_pending.
3752
3753 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
3754
3755 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
3756
3757 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
3758 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
3759 as passed in.
3760
3761 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
3762
3763 * xterm.c (x_set_frame_alpha): Do not set property on anything

3791
3792 * sysdep.c (interruptible_wait_for_termination): New function
3793 which is like wait_for_termination, but allows keyboard
3794 interruptions.
3795
3796 * callproc.c (Fcall_process): Add (:file "file") as an option for
3797 the STDOUT buffer.

3803 rather than `XVECTOR (FOO)->size'.
3804
3805 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
3806 inttypes.h, as a gnulib replacement is used if it not available in
3807 system headers.

3813 of MOST_POSITIVE_FIXNUM. (Bug#8528)
3814
3815 * coding.c (coding_alloc_by_realloc): Error out if destination
3816 will grow beyond MOST_POSITIVE_FIXNUM.

3836 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
3837

3872
3873 Improve `doprnt' and its usage. (Bug#8545)
3874 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
3875 `format_end'. Remove support for %l as a conversion specifier.
3876 Don't use xrealloc. Improve diagnostics when the %l size modifier
3877 is used. Update the commentary.
3878
3879 * eval.c (verror): Simplify calculation of size_t.
3880
3881 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
3882 messages.

3887 change.
3888
3889 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3890
3891 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
3892 This makes this file independent of the recent pseudovector change.
3893
3894 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
3895
3896 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
3897
3898 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
3899 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
3900 Remove unused local.
3901 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
3902
3903 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
3904 GCC 4.6.0 optimizes based on type-based alias analysis.
3905 For example, if b is of type struct buffer * and v of type struct
3906 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
3907 != &v->size, and therefore "v->size = 1; b->size = 2; return
3908 v->size;" must therefore return 1. This assumption is incorrect
3909 for Emacs, since it type-puns struct Lisp_Vector * with many other
3910 types. To fix this problem, this patch adds a new type struct
3911 vectorlike_header that documents the constraints on layout of vectors
3912 and pseudovectors, and helps optimizing compilers not get fooled
3913 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
3914 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
3915 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
3916 the size member.
3917 (XSETPVECTYPE): Rewrite in terms of new macro.
3918 (XSETPVECTYPESIZE): New macro, specifying both type and size.
3919 This is a bit clearer, and further avoids the possibility of
3920 undesirable aliasing.
3921 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
3922 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
3923 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
3924 since Lisp_Subr is a special case (no "next" field).
3925 (ASIZE): Now uses header.size rather than size.
3926 All previous uses of XVECTOR (foo)->size replaced to use this macro,
3927 to avoid the hassle of writing XVECTOR (foo)->header.size.
3928 (struct vectorlike_header): New type.
3929 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
3930 object, to help avoid aliasing.
3931 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
3932 (SUBRP): Likewise, since Lisp_Subr is a special case.
3933 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
3934 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
3935 (struct Lisp_Hash_Table): Combine first two members into a single
3936 struct vectorlike_header member. All uses of "size" and "next" members
3937 changed to be "header.size" and "header.next".
3938 * buffer.h (struct buffer): Likewise.
3939 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
3940 * frame.h (struct frame): Likewise.
3941 * process.h (struct Lisp_Process): Likewise.
3942 * termhooks.h (struct terminal): Likewise.
3943 * window.c (struct save_window_data, struct saved_window): Likewise.
3944 * window.h (struct window): Likewise.
3945 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
3946 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
3947 * buffer.c (init_buffer_once): Likewise.
3948 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
3949 special case.
3950 * process.c (Fformat_network_address): Use local var for size,
3951 for brevity.
3952
3953 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
3954
3955 Make the Lisp reader and string-to-float more consistent (Bug#8525)
3956 * data.c (atof): Remove decl; no longer used or needed.
3957 (digit_to_number): Move to lread.c.
3958 (Fstring_to_number): Use new string_to_number function, to be
3959 consistent with how the Lisp reader treats infinities and NaNs.
3960 Do not assume that floating-point numbers represent EMACS_INT
3961 without losing information; this is not true on most 64-bit hosts.
3962 Avoid double-rounding errors, by insisting on integers when
3963 parsing non-base-10 numbers, as the documentation specifies.
3964 * lisp.h (string_to_number): New decl, replacing ...
3965 (isfloat_string): Remove.
3966 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
3967 (read1): Do not accept +. and -. as integers; this
3968 appears to have been a coding error. Similarly, do not accept
3969 strings like +-1e0 as floating point numbers. Do not report
3970 overflow for integer overflows unless the base is not 10 which
3971 means we have no simple and reliable way to continue.
3972 Break out the floating-point parsing into a new
3973 function string_to_number, so that Fstring_to_number parses
3974 floating point numbers consistently with the Lisp reader.
3975 (digit_to_number): Move here from data.c. Make it static inline.
3976 (E_CHAR, EXP_INT): Remove, replacing with ...
3977 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
3978 (string_to_number): New function, replacing isfloat_string.
3979 This function checks for valid syntax and produces the resulting
3980 Lisp float number too. Rework it so that string-to-number
3981 no longer mishandles examples like "1.0e+". Use strtoumax,
3982 so that overflow for non-base-10 numbers is reported only when
3983 there's no portable and simple way to convert to floating point.
3984
3985 * textprop.c (set_text_properties_1): Rewrite for clarity,
3986 and to avoid GCC warning about integer overflow.
3987
3988 * intervals.h (struct interval): Use EMACS_INT for members
3989 where EMACS_UINT might cause problems. See
3990 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
3991 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
3992 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
3993 All uses changed.
3994 (offset_intervals): Tell GCC not to worry about length overflow
3995 when negating a negative length.
3996
3997 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
3998 (overrun_check_free): Likewise.
3999
4000 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
4001 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
4002 word size.
4003
4004 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4005 (gnutls_make_error): Rename local to avoid shadowing.
4006 (gnutls_emacs_global_deinit): ifdef out; not used.
4007 (Fgnutls_boot): Use const for pointer to readonly storage.
4008 Comment out unused local. Fix pointer signedness problems.
4009
4010 * lread.c (openp): Don't stuff size_t into an 'int'.
4011 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
4012 about possible signed overflow.
4013
4014 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4015 (GDK_KEY_g): Don't define if already defined.
4016 (xg_prepare_tooltip): Avoid pointer signedness problem.
4017 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
4018
4019 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
4020 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
4021
4022 * xfns.c (Fx_window_property): Simplify a bit,
4023 to make a bit faster and to avoid GCC 4.6.0 warning.
4024 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
4025
4026 * fns.c (internal_equal): Don't assume size_t fits in int.
4027
4028 * alloc.c (compact_small_strings): Tighten assertion a little.
4029
4030 Replace pEd with more-general pI, and fix some printf arg casts.
4031 * lisp.h (pI): New macro, generalizing old pEd macro to other
4032 conversion specifiers. For example, use "...%"pI"d..." rather
4033 than "...%"pEd"...".
4034 (pEd): Remove. All uses replaced with similar uses of pI.
4035 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
4036 * alloc.c (check_pure_size): Don't overflow by converting size to int.
4037 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
4038 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
4039 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
4040 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
4041 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
4042 64-bit hosts.
4043 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
4044 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
4045 * print.c (safe_debug_print, print_object): Likewise.
4046 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
4047 to int.
4048 Use pI instead of if-then-else-abort. Use %p to avoid casts,
4049 avoiding the 0 flag, which is not portable.
4050 * process.c (Fmake_network_process): Use pI to avoid cast.
4051 * region-cache.c (pp_cache): Likewise.
4052 * xdisp.c (decode_mode_spec): Likewise.
4053 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
4054 behavior on 64-bit hosts with printf arg.
4055 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
4056 (x_stop_queuing_selection_requests): Likewise.
4057 (x_get_window_property): Don't truncate byte count to an 'int'
4058 when tracing.
4059
4060 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
4061 here, since it parses constructs like leading '-' and spaces,
4062 which are not wanted; and it overflows with large numbers.
4063 Instead, simply match F[0-9]+, which is what is wanted anyway.
4064
4065 * alloc.c: Remove unportable assumptions about struct layout.
4066 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
4067 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
4068 (allocate_vectorlike, make_pure_vector): Use the new macros,
4069 plus offsetof, to remove unportable assumptions about struct layout.
4070 These assumptions hold on all porting targets that I know of, but
4071 they are not guaranteed, they're easy to remove, and removing them
4072 makes further changes easier.
4073
4074 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
4075 This doesn't fix a bug but makes the code clearer.
4076 (string_overrun_cookie): Now const. Use initializers that
4077 don't formally overflow signed char, to avoid warnings.
4078 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
4079 can cause Emacs to crash when string overrun checking is enabled.
4080 (allocate_buffer): Don't assume sizeof (struct buffer) is a
4081 multiple of sizeof (EMACS_INT); it need not be, if
4082 alignof(EMACS_INT) < sizeof (EMACS_INT).
4083 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
4084
4085 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
4086
4087 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.

4092 supposed to be handshaking. (Bug#8556)
4093 Reported by Paul Eggert <eggert@cs.ucla.edu>.
4094
4095 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
4096
4097 * lisp.h (Qdebug): List symbol.
4098 * eval.c (Qdebug): Restore global linkage.
4099 * keyboard.c (debug-on-event): New variable.
4100 (handle_user_signal): Break into debugger when debug-on-event
4101 matches the current signal symbol.
4102
4103 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
4104
4105 * alloc.c (check_sblock, check_string_bytes)
4106 (check_string_free_list): Convert to standard C.
4107
4108 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
4109
4110 * w32.c (emacs_gnutls_push): Fix typo.
4111
4112 2011-04-25 Eli Zaretskii <eliz@gnu.org>
4113
4114 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
4115 "cast to pointer from integer of different size".
4116
4117 Improve doprnt and its use in verror. (Bug#8545)
4118 * doprnt.c (doprnt): Document the set of format control sequences
4119 supported by the function. Use SAFE_ALLOCA instead of always
4120 using `alloca'.
4121
4122 * eval.c (verror): Don't limit the buffer size at size_max-1, that
4123 is one byte too soon. Don't use xrealloc; instead xfree and
4124 xmalloc anew.
4125
4126 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
4127
4128 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
4129 callbacks stage.
4130
4131 * gnutls.c: Renamed global_initialized to
4132 gnutls_global_initialized. Added internals for the
4133 :verify-hostname-error, :verify-error, and :verify-flags
4134 parameters of `gnutls-boot' and documented those parameters in the
4135 docstring. Start callback support.
4136 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
4137 unless a fatal error occurred. Call gnutls_alert_send_appropriate
4138 on error. Return error code.
4139 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
4140 (emacs_gnutls_read): Likewise.
4141 (Fgnutls_boot): Return handshake error code.
4142 (emacs_gnutls_handle_error): New function.
4143 (wsaerror_to_errno): Likewise.

4147
4148 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
4149 (emacs_gnutls_push): Likewise.
4150

4152
4153 * process.c (wait_reading_process_output): Check if GnuTLS
4154 buffered some data internally if no FDs are set for TLS
4155 connections.
4156
4157 * makefile.w32-in (OBJ2): Add gnutls.$(O).
4158 (LIBS): Link to USER_LIBS.

4162
4163 * xdisp.c (handle_single_display_spec): Rename the
4164 display_replaced_before_p argument into display_replaced_p, to
4165 make it consistent with the commentary. Fix typos in the
4166 commentary.
4167

4627 * insdel.c: Make symbols static if they're not exported.
4628 However, leave prepare_to_modify_buffer alone. It's never

4809
4810 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.

4853
4854 Make Emacs functions such as Fatom 'static' by default.
4855 This makes it easier for human readers (and static analyzers)
4856 to see whether these functions can be called from other modules.
4857 DEFUN now defines a static function. To make the function external
4858 so that it can be used in other C modules, use the new macro DEFUE.

4934 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
4935
4936 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
4937 since callers should never pass a negative size.
4938 Change the signature to match that of plain 'read' and 'write'; see
4939 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
4940 * lisp.h: Update prototypes of emacs_write and emacs_read.
4941
4942 2011-04-11 Eli Zaretskii <eliz@gnu.org>
4943
4944 * xdisp.c (redisplay_window): Don't try to determine the character
4945 position of the scroll margin if the window start point w->startp
4946 is outside the buffer's accessible region. (Bug#8468)
4947
4948 2011-04-10 Eli Zaretskii <eliz@gnu.org>
4949
4950 Fix write-region and its subroutines for buffers > 2GB.
4951 * fileio.c (a_write, e_write): Modify declaration of arguments and
4952 local variables to support buffers larger than 2GB.
4953 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
4954
4955 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last

4962 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
4963
4964 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
4965
4966 Fix more problems found by GCC 4.6.0's static checks.
4967
4968 * xdisp.c (vmessage): Use a better test for character truncation.
4969
4970 * charset.c (load_charset_map): <, not <=, for optimization,

4977 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
4978 This also lets GCC 4.6.0 generate slightly better loop code.
4979
4980 * callint.c (Fcall_interactively): <, not <=, for optimization.
4981 (Fcall_interactively): Count the number of arguments produced,
4982 not the number of arguments given. This is simpler and lets GCC
4983 4.6.0 generate slightly better code.
4984
4985 * ftfont.c: Distingish more carefully between FcChar8 and char.
4986 The previous code passed unsigned char * to a functions like
4987 strlen and xstrcasecmp that expect char *, which does not
4988 conform to the C standard.
4989 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
4990 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
4991 char * when the C standard requires it.
4992
4993 * keyboard.c (read_char): Remove unused var.
4994
4995 * eval.c: Port to Windows vsnprintf (Bug#8435).
4996 Include <limits.h>.
4997 (SIZE_MAX): Define if the headers do not.
4998 (verror): Do not give up if vsnprintf returns a negative count.
4999 Instead, grow the buffer. This ports to Windows vsnprintf, which
5000 does not conform to C99. Problem reported by Eli Zaretskii.
5001 Also, simplify the allocation scheme, by avoiding the need for
5002 calling realloc, and removing the ALLOCATED variable.
5003
5004 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
5005
5006 Remove invocations of doprnt, as Emacs now uses vsnprintf.
5007 But keep the doprint source code for now, as we might revamp it
5008 and use it again (Bug#8435).
5009 * lisp.h (doprnt): Remove.
5010 * Makefile.in (base_obj): Remove doprnt.o.
5011 * deps.mk (doprnt.o): Remove.
5012
5013 error: Print 32- and 64-bit integers portably (Bug#8435).
5014 Without this change, on typical 64-bit hosts error ("...%d...", N)
5015 was used to print both 32- and 64-bit integers N, which relied on
5016 undefined behavior.
5017 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
5018 New macro.
5019 * lisp.h (error, verror): Mark as printf-like functions.
5020 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
5021 Report overflow in size calculations when allocating printf buffer.
5022 Do not truncate output string at its first null byte.
5023 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
5024 Truncate the output at a character boundary, since vsnprintf does not
5025 do that.
5026 * charset.c (check_iso_charset_parameter): Convert internal
5027 character to string before calling 'error', since %c now has the
5028 printf meaning.
5029 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
5030 overflow when computing char to be passed to 'error'. Do not
5031 pass Lisp_Object to 'error'; pass the integer instead.
5032 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
5033 formatted with plain %d.
5034
5035 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
5036
5037 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
5038
5039 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
5040
5041 * xterm.c (x_catch_errors): Remove duplicate declaration.
5042
5043 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
5044
5045 * xdisp.c, lisp.h (message_nolog): Remove; unused.
5046

5050 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
5051 return ssize_t not "int", and use size_t as the buffer length.
5052 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
5053 * gnutls.h: Update declarations.
5054 * process.c (read_process_output): Use ssize_t, to match.
5055 (send_process): Likewise.
5056

5062
5063 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
5064 Use unsigned char, to match FcChar8 type definition.
5065
5066 * xterm.c (handle_one_xevent):
5067 * xmenu.c (create_and_show_popup_menu):
5068 * xselect.c (x_decline_selection_request)
5069 (x_reply_selection_request): Avoid type-punned deref of X events.
5070
5071 2011-04-09 Eli Zaretskii <eliz@gnu.org>

5076 (scan_buffer, find_next_newline_no_quit)
5077 (find_before_next_newline, search_command, Freplace_match)
5078 (Fmatch_data): Make some `int' variables be EMACS_INT.
5079
5080 * xdisp.c (display_count_lines): 3rd argument and return value now
5081 EMACS_INT. All callers changed.

5107 All users changed.
5108
5109 * ccl.c (Fccl_execute_on_string): Declare some variables
5110 EMACS_INT.

5121
5122 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
5123
5124 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
5125

5127 instead of using internal_with_output_to_temp_buffer.
5128 (Qhelp_form_show): New var.
5129 (syms_of_keyboard): Use DEFSYM macro.
5130
5131 * print.c (internal_with_output_to_temp_buffer): Function deleted.
5132
5133 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
5134

5143
5144 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
5145
5146 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
5147
5148 Fix more problems found by GCC 4.6.0's static checks.
5149

5170 This avoids several warnings with gcc -Wstrict-overflow.
5171 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
5172 directly, rather than having caller test rule sign. This avoids
5173 some unnecessary tests.
5174 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
5175 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
5176 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

5190 by using the new macro.
5191
5192 * textprop.c (set_text_properties_1): Change while to do-while,
5193 since the condition is always true at first.
5194
5195 * intervals.c (graft_intervals_into_buffer): Mark var as used.
5196 (interval_deletion_adjustment): Return unsigned value.
5197 All uses changed.

5218 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
5219
5220 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
5221 (font_score): Avoid potential overflow in diff calculation.
5222
5223 * fns.c (substring_both): Remove var that is set but not used.
5224 (sxhash): Redo loop for clarity and to avoid wraparound warning.
5225
5226 * eval.c (funcall_lambda): Rename local to avoid shadowing.
5227
5228 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
5229 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
5230 can always succeed if overflow has undefined behavior.
5231
5232 * search.c (boyer_moore, wordify): Remove vars set but not used.
5233 (wordify): Omit three unnecessary tests.
5234
5235 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

5239
5240 * dired.c (file_name_completion): Remove var that is set but not used.

5251 but not used.
5252

5264 that are set but not used.
5265

5282 (map_tty_color) [!defined MSDOS]: Likewise.
5283

5287 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
5288 All callers changed.

5298 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
5299 The gnulib version avoids calling malloc in the usual case,
5300 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
5301 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
5302 * filelock.c (current_lock_owner): Likewise.
5303 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

5414 (redisplay_window): Even when falling back on "recentering",
5415 position point in the window according to scroll-conservatively,
5416 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
5417
5418 (try_scrolling): When point is above the window, allow searching
5419 as far as scroll_max, or one screenful, to compute vertical
5420 distance from PT to the scroll margin position. This prevents
5421 try_scrolling from unnecessarily failing when
5422 scroll-conservatively is set to a value slightly larger than the
5423 window height. Clean up the case of PT below the margin at bottom
5424 of window: scroll_max can no longer be INT_MAX. When aggressive
5425 scrolling is in use, don't let point enter the opposite scroll
5426 margin as result of the scroll.
5427 (syms_of_xdisp) <scroll-conservatively>: Document the
5428 threshold of 100 lines for never-recentering scrolling.

5431
5432 * dispextern.h (move_it_by_lines):
5433 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
5434 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
5435 (message_log_check_duplicate): Remove parameters `prev_bol' and
5436 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5437 (redisplay_internal): Remove parameter `preserve_echo_area',
5438 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
5439
5440 * indent.c (Fvertical_motion):
5441 * window.c (window_scroll_pixel_based, Frecenter):
5442 Don't pass `need_y_p' to `move_it_by_lines'.
5443
5444 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
5445
5446 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
5447 steal a few bits to be more compact.
5448 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
5449 Remove unneeded casts.
5450
5451 * bytecode.c (Fbyte_code): CAR and CDR can GC.
5452
5453 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
5454
5455 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
5456 binding" message (bug#7967).
5457
5458 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
5459
5460 Fix more problems found by GCC 4.6.0's static checks.
5461
5462 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
5463 Remove unused local var.
5464
5465 * editfns.c (Fmessage_box): Remove unused local var.
5466
5467 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
5468 (note_mode_line_or_margin_highlight, note_mouse_highlight):
5469 Omit unused local vars.
5470 * window.c (shrink_windows): Omit unused local var.
5471 * menu.c (digest_single_submenu): Omit unused local var.
5472 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
5473 Omit unused local var.
5474
5475 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
5476 Don't assume string length fits in int.
5477 (keyremap_step, read_key_sequence): Use size_t for sizes.
5478 (read_key_sequence): Don't check last_real_key_start redundantly.
5479
5480 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
5481 instead of alloca (Bug#8344).
5482
5483 * eval.c (Fbacktrace): Don't assume nargs fits in int.
5484 (Fbacktrace_frame): Don't assume nframes fits in int.
5485
5486 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
5487
5488 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
5489 concerns.
5490
5491 * term.c (produce_glyphless_glyph): Remove unnecessary test.
5492
5493 * cm.c (calccost): Turn while-do into do-while, for clarity.
5494
5495 * keyboard.c (syms_of_keyboard): Use the same style as later
5496 in this function when indexing through an array. This also
5497 works around GCC bug 48267.
5498
5499 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
5500
5501 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
5502

5504 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
5505
5506 * keyboard.c, keyboard.h (num_input_events): Now size_t.
5507 This avoids undefined behavior on integer overflow, and is a bit
5508 more convenient anyway since it is compared to a size_t variable.
5509
5510 Variadic C functions now count arguments with size_t, not int.
5511 This avoids an unnecessary limitation on 64-bit machines, which
5512 caused (substring ...) to crash on large vectors (Bug#8344).
5513 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
5514 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
5515 All variadic functions and their callers changed accordingly.

5520 (internal_condition_case_n, run_hook_with_args, apply_lambda)
5521 (funcall_lambda, mark_backtrace): Likewise.
5522 * fns.c (concat): Likewise.
5523 * frame.c (x_set_frame_parameters): Likewise.
5524 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
5525 0 if not found, not -1. All callers changed.
5526
5527 * alloc.c (garbage_collect): Don't assume stack size fits in int.
5528 (stack_copy_size): Now size_t, not int.
5529 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
5530

5535 All callers changed.
5536
5537 * lisp.h (multibyte_char_to_unibyte):
5538 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
5539 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
5540 * character.h (CHAR_TO_BYTE8):
5541 * cmds.c (internal_self_insert):
5542 * editfns.c (general_insert_function):
5543 * keymap.c (push_key_description):
5544 * search.c (Freplace_match):
5545 * xdisp.c (message_dolog, set_message_1): All callers changed.
5546

5548
5549 * keyboard.c (safe_run_hook_funcall): New function.
5550 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
5551 don't set the hook to nil, but remove the offending function instead.
5552 (Qcommand_hook_internal): Remove, unused.
5553 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
5554 Vcommand_hook_internal.
5555
5556 * eval.c (enum run_hooks_condition): Remove.
5557 (funcall_nil, funcall_not): New functions.
5558 (run_hook_with_args): Call each function through a `funcall' argument.

5561 (Frun_hook_with_args_until_failure): Adjust accordingly.
5562 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
5563
5564 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
5565
5566 * dispextern.h (string_buffer_position): Remove declaration.
5567
5568 * print.c (strout): Remove parameter `multibyte', unused since
5569 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
5570
5571 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
5572 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
5573 All callers changed.
5574
5575 * w32.c (_wsa_errlist): Use braces for struct initializers.
5576
5577 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
5578 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.

5601 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
5602
5603 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
5604
5605 * nsmenu.m (runDialogAt): Remove argument to timer_check.
5606

5615
5616 2011-03-26 Eli Zaretskii <eliz@gnu.org>
5617
5618 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
5619 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
5620
5621 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
5622
5623 * w32.c (read_unc_volume): Use parameter `henum', instead of
5624 global variable `wget_enum_handle'.
5625
5626 * keymap.c (describe_vector): Remove parameters `indices' and
5627 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
5628 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
5629
5630 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
5631
5632 * keyboard.c (timer_check): Remove parameter `do_it_now',
5633 unused since 1996-04-12T06:01:29Z!rms@gnu.org.

5638 * w32menu.c (w32_menu_display_help):
5639 * xmenu.c (show_help_event, menu_help_callback):

5701
5702 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

5704 (Fx_close_connection): Remove unused variable `i'.
5705
5706 * w32font.c (w32font_draw): Return number of glyphs.
5707 (w32font_open_internal): Remove unused variable `i'.
5708 (w32font_driver): Add missing initializer.
5709

5721
5722 2011-03-23 Julien Danjou <julien@danjou.info>
5723
5724 * term.c (Fsuspend_tty, Fresume_tty):
5725 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
5726 * window.c (temp_output_buffer_show):
5727 * insdel.c (signal_before_change):

5735 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
5736 Use Frun_hooks.
5737 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
5738 unconditionnaly since it does the check itself.
5739
5740 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
5741
5742 Fix more problems found by GCC 4.5.2's static checks.
5743
5744 * coding.c (encode_coding_raw_text): Avoid unnecessary test
5745 the first time through the loop, since we know p0 < p1 then.
5746 This also avoids a gcc -Wstrict-overflow warning.
5747
5748 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
5749 leading to a memory leak, possible in functions like
5750 load_charset_map_from_file that can allocate an unbounded number
5751 of objects (Bug#8318).
5752
5753 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
5754 that could (at least in theory) be that large.
5755
5756 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
5757 This is less likely to overflow, and avoids undefined behavior if
5758 overflow does occur. All callers changed. Use strtoul to scan
5759 for the unsigned long integer.
5760 (pint2hrstr): Simplify and tune code slightly.
5761 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
5762
5763 * scroll.c (do_scrolling): Work around GCC bug 48228.
5764 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
5765
5766 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
5767 This also avoids a warning with gcc -Wstrict-overflow.
5768 (validate_x_resource_name): Simplify count usage.
5769 This also avoids a warning with gcc -Wstrict-overflow.
5770
5771 * fileio.c (Fcopy_file): Report error if fchown or fchmod
5772 fail (Bug#8306).
5773
5774 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
5775
5776 * process.c (Fmake_network_process): Use socklen_t, not int,
5777 where POSIX says socklen_t is required in portable programs.
5778 This fixes a porting bug on hosts like 64-bit HP-UX, where
5779 socklen_t is wider than int (Bug#8277).
5780 (Fmake_network_process, server_accept_connection):
5781 (wait_reading_process_output, read_process_output):
5782 Likewise.
5783
5784 * process.c: Rename or move locals to avoid shadowing.
5785 (list_processes_1, Fmake_network_process):
5786 (read_process_output_error_handler, exec_sentinel_error_handler):
5787 Rename or move locals.
5788 (Fmake_network_process): Define label "retry_connect" only if needed.
5789 (Fnetwork_interface_info): Fix pointer signedness.
5790 (process_send_signal): Add cast to avoid pointer signedness problem.
5791 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
5792 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
5793
5794 Make tparam.h and terminfo.c consistent.
5795 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
5796 Include tparam.h instead, since it declares them.
5797 * cm.h (PC): Remove extern decl; tparam.h now does this.
5798 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
5799 * terminfo.c: Include tparam.h, to check interfaces.
5800 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
5801 (tparam): Adjust signature to match interface in tparam.h;
5802 this removes some undefined behavior. Check that outstring and len
5803 are zero, which they always are with Emacs.
5804 * tparam.h (PC, BC, UP): New extern decls.
5805
5806 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
5807 (xftfont_open): Rename locals to avoid shadowing.
5808
5809 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
5810 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
5811 (OTF_TAG_SYM): Omit macro if not needed.
5812 (ftfont_list): Remove unused local.
5813 (get_adstyle_property, ftfont_pattern_entity):
5814 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
5815 Rename locals to avoid shadowing.
5816

5859
5860 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
5861 This should get cleaned up, so that child_setup has the
5862 same signature on all platforms.
5863
5864 * callproc.c (call_process_cleanup): Now static.
5865 (relocate_fd): Rename locals to avoid shadowing.

5867 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
5868
5869 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
5870 not to be necessary, and produces flickering.
5871

5873
5874 * config.in: Remove file.

5991 Move decls here, to check interfaces.
5992 * process.c (get_operating_system_release): Move decl to lisp.h.
5993 * xrdb.c (get_system_name): Likewise.
5994 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
5995 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
5996 some of which prompt warnings from gcc -Wbad-function-cast.

6026 (Fmemory_limit): Cast sbrk's returned value to char *.
6027

6030
6031 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
6032
6033 Use functions, not macros, for up- and down-casing (Bug#8254).
6034 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6035 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
6036 to use the following functions instead of these macros.
6037 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
6038 EMACS_INT, since callers assume the returned value fits in int.
6039 (upcase1): Likewise, for UPCASE_TABLE.
6040 (uppercasep, lowercasep, upcase): New static inline functions.
6041 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

6047 (regex_compile, re_search_2, re_match_2_internal):
6048 Remove unused local vars.

6050 which gcc can warn about.
6051 (regex_compile, re_match_2_internal): Mark locals as initialized.
6052 (RETALLOC_IF): Define only if needed.
6053 (WORDCHAR_P): Likewise. This one is never needed, but is used
6054 only in a comment talking about a compiler bug, so put inside
6055 the #if 0 of that comment.
6056 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
6057 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
6058 Remove; unused.

6069
6070 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
6071
6072 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
6073 All uses changed.
6074 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
6075 Rename locals to avoid shadowing.
6076 (Fvertical_motion): Mark locals as initialized.
6077
6078 * casefiddle.c (casify_object, casify_region): Now static.

6082
6083 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
6084 New macros, so that the caller can use some names other than
6085 gcpro1, gcpro2, etc.
6086 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
6087 of the new macros.
6088 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
6089 argument, for consistency with GCPRO2_VAR, etc: it is now the
6090 prefix of the variable, not the variable itself. All uses
6091 changed.
6092 * dired.c (directory_files_internal, file_name_completion):
6093 Rename locals to avoid shadowing.
6094
6095 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
6096 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
6097 dired.c's scmp function, had undefined behavior.
6098 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6099 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
6100 * buffer.h: ... to here, because these macros use current_buffer,
6101 and the new implementation with inline functions needs to have
6102 current_buffer in scope now, rather than later when the macros
6103 are used.
6104 (downcase, upcase1): New static inline functions.
6105 (DOWNCASE, UPCASE1): Reimplement using these functions.
6106 This avoids undefined behavior in expressions like
6107 DOWNCASE (x) == DOWNCASE (y), which previously suffered
6108 from race conditions in accessing the global variables
6109 case_temp1 and case_temp2.
6110 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
6111 * lisp.h (case_temp1, case_temp2): Remove their decls.
6112 * character.h (ASCII_CHAR_P): Move from here ...
6113 * lisp.h: ... to here, so that the inline functions mentioned
6114 above can use them.
6115
6116 * dired.c (directory_files_internal_unwind): Now static.
6117
6118 * fileio.c (file_name_as_directory, directory_file_name):
6119 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
6120 Now static.
6121 (file_name_as_directory): Use const pointers when appropriate.
6122 (Fexpand_file_name): Likewise. In particular, newdir might
6123 point at constant storage, so make it a const pointer.
6124 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
6125 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
6126 signedness issues.
6127 (Fset_file_times, Finsert_file_contents, auto_save_error):
6128 Rename locals to avoid shadowing.
6129
6130 * minibuf.c (choose_minibuf_frame_1): Now static.
6131 (Ftry_completion, Fall_completions): Rename or remove locals
6132 to avoid shadowing.
6133
6134 * marker.c (bytepos_to_charpos): Remove; unused.
6135
6136 * lisp.h (verify_bytepos, count_markers): New decls,
6137 so that gcc does not warn that these functions aren't declared.
6138
6139 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
6140 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
6141 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
6142 (copy_text): Remove unused local var.
6143
6144 * filelock.c (within_one_second): Now static.
6145 (lock_file_1): Rename local to avoid shadowing.
6146
6147 * buffer.c (fix_overlays_before): Mark locals as initialized.
6148 (fix_start_end_in_overlays): Likewise. This function should be
6149 simplified by using pointers-to-pointers, but that's a different
6150 matter.
6151 (switch_to_buffer_1): Now static.
6152 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
6153 (report_overlay_modification): Rename locals to avoid shadowing.
6154
6155 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
6156 Fix pointer signedness issue.
6157 (sys_subshell): Mark local as volatile if checking for lint,
6158 to suppress a gcc -Wclobbered warning that does not seem to be right.
6159 (MAXPATHLEN): Define only if needed.
6160
6161 * process.c (serial_open, serial_configure): Move decls from here ...
6162 * systty.h: ... to here, so that they can be checked.
6163
6164 * fns.c (get_random, seed_random): Move extern decls from here ...
6165 * lisp.h: ... to here, so that they can be checked.
6166
6167 * sysdep.c (reset_io): Now static.
6168 (wait_for_termination_signal): Remove; unused.
6169
6170 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
6171 (copy_keymap_item, append_key, push_text_char_description):
6172 Now static.
6173 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
6174 (DENSE_TABLE_SIZE): Remove; unused.
6175 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
6176 (describe_map_tree):
6177 Rename locals to avoid shadowing.
6178
6179 * keyboard.c: Declare functions static if they are not used elsewhere.
6180 (echo_char, echo_dash, cmd_error, top_level_2):
6181 (poll_for_input, handle_async_input): Now static.
6182 (read_char, kbd_buffer_get_event, make_lispy_position):
6183 (make_lispy_event, make_lispy_movement, apply_modifiers):
6184 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):

6193
6194 * lisp.h (force_auto_save_soon): New decl.
6195
6196 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
6197 (DEFINE_DUMMY_FUNCTION): New macro.
6198 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
6199 Use it.
6200 (main): Add casts to avoid warnings
6201 if GCC considers string literals to be constants.
6202
6203 * lisp.h (fatal_error_signal): Add decl, since it's exported.
6204
6205 * dbusbind.c: Pointer signedness fixes.
6206 (xd_signature, xd_append_arg, xd_initialize):
6207 (Fdbus_call_method, Fdbus_call_method_asynchronously):
6208 (Fdbus_method_return_internal, Fdbus_method_error_internal):
6209 (Fdbus_send_signal, xd_read_message_1, Fdbus_register_service):
6210 (Fdbus_register_signal): Use SSDATA when the context wants char *.
6211
6212 * dbusbind.c (Fdbus_init_bus): Add cast to avoid warning
6213 if GCC considers string literals to be constants.
