6 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
8 * nsfont.m (ns_otf_to_script): Fix typo.
10 2011-08-22 Kenichi Handa <handa@m17n.org>
12 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
13 extra slot even if the purpose is char-code-property-table.
15 2011-08-23 Eli Zaretskii <eliz@gnu.org>
17 * xdisp.c (redisplay_window): When computing centering_position,
18 account for the height of the header line. (Bug#8874)
20 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
21 instead of CHAR_TO_BYTE. Fixes a crash when a completion
22 candidate is selected by the mouse, and that candidate has a
23 composed character under the mouse.
25 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
26 coordinates reported by pos-visible-in-window-p for a composed
27 character in column zero.
29 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
31 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
33 2011-08-22 Eli Zaretskii <eliz@gnu.org>
35 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
36 consider it a hit if to_charpos is anywhere in the range of the
37 composed buffer positions.
39 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
41 * image.c (gif_load): Don't assume that each subimage has the same
42 dimensions as the base image. Handle disposal method that is
43 "undefined" by the gif spec (Bug#9335).
45 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
47 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
48 (Fcondition_case): Document `debug' symbol in error handler.
50 2011-08-19 Eli Zaretskii <eliz@gnu.org>
52 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
53 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
54 from an Org mode buffer to a Speedbar frame.
56 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
57 a composition, take its buffer position from IT->cmp_it.charpos.
58 Fixes cursor positioning at the beginning of a line that begins
59 with a composed character.
61 2011-08-18 Eli Zaretskii <eliz@gnu.org>
63 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
64 character bidirectional type, use STRONG_L instead. Fixes crashes
65 in a buffer produced by `describe-categories'.
67 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
68 members before the level stack, so they would be saved and
69 restored when copying iterator state. Fixes incorrect reordering
70 around TABs covered by display properties.
72 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
74 * process.c (Fnetwork_interface_list): Correctly determine buffer
77 2011-08-17 Chong Yidong <cyd@stupidchicken.com>

80 (internal_condition_case_2, internal_condition_case_n):
81 Remove unnecessary aborts (Bug#9081).
83 2011-08-17 Eli Zaretskii <eliz@gnu.org>
85 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
86 has no `load' handler, try opening the file locally. (Bug#9311)
88 2011-08-16 Ken Brown <kbrown@cornell.edu>
90 * gmalloc.c: Expand comment.
92 2011-08-16 Eli Zaretskii <eliz@gnu.org>
94 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
95 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
97 2011-08-16 Ken Brown <kbrown@cornell.edu>
99 Fix memory allocation problems in Cygwin build (Bug#9273).
101 * unexcw.c ( __malloc_initialized): Declare external variable.
102 (fixup_executable): Force the dumped emacs to reinitialize malloc.

108 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
110 [CYGWIN] (special_realloc): New function.
111 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
112 requests to realloc storage in the static heap.

120 * biditype.h: File removed.
122 * bidimirror.h: File removed.
124 * deps.mk (bidi.o): Remove biditype.h and
127 * makefile.w32-in ($(BLD)/bidi.$(O)): Remove biditype.h and
130 * dispextern.h: Fix a typo in the comment to bidi_type_t.
132 * chartab.c: Improve commentary for the uniprop_table API.
134 * bidi.c (bidi_paragraph_init): Support zero value of
135 bidi_ignore_explicit_marks_for_paragraph_level.
136 (bidi_initialize): Use uniprop_table instead of including
137 biditype.h and bidimirror.h.
139 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
140 coordinates of the iterator when restoring from ppos_it.
143 2011-08-14 Kenichi Handa <handa@m17n.org>
145 * process.c (create_process): Call setup_process_coding_systems
146 after the pid of the process is set to -1 (Bug#8162).
148 2011-08-14 Eli Zaretskii <eliz@gnu.org>
150 * xdisp.c (move_it_in_display_line_to): Don't invoke
151 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
152 ppos_it. Fixes vertical cursor motion when line beginning is
153 covered by an image. (Bug#9296)
155 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
157 * nsterm.h (ns_run_ascript): Declare.
158 (NSAPP_DATA2_RUNASSCRIPT): Define.
160 * nsfns.m (as_script, as_result, as_status): New static variables.
161 (ns_run_ascript): New function.
162 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
163 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
164 the event loop. Get status from as_status (Bug#7276).
166 * nsterm.m (sendEvent): If event is NSApplicationDefined and
167 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
168 the event loop (Bug#7276).
170 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
172 * gnutls.c (QCgnutls_bootprop_priority)
173 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
174 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
175 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)

177 (QCgnutls_bootprop_verify_hostname_error)
178 (QCgnutls_bootprop_callbacks_verify): Rename from
179 Qgnutls_bootprop_..., all uses changed.

193 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
194 (Fnetwork_interface_list): Allocate in increments of bytes instead
195 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
196 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
198 (struct ifflag_def): notrailers is smart on OSX.
199 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
200 Get hardware address with getifaddrs if available.
202 2011-08-12 Eli Zaretskii <eliz@gnu.org>
204 * xdisp.c (iterate_out_of_display_property): xassert that
205 IT->position is set to within IT->object's boundaries. Break from
206 the loop as soon as EOB is reached; avoids infloops in redisplay
207 when IT->position is set up wrongly due to some bug.
208 Set IT->current to match the bidi iterator unconditionally.
209 (push_display_prop): Allow GET_FROM_STRING as IT->method on
210 entry. Force push_it to save on the stack the current
211 buffer/string position, to be restored by pop_it. Fix flags in
212 the iterator structure wrt the object coming from a display
213 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
214 properties. (Bug#9284)
216 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
218 * fontset.c (fontset_get_font_group): Add proper type checks.

226 (dump_it) [LC_FUNCTION_STARTS]: Use it.
228 2011-08-08 Eli Zaretskii <eliz@gnu.org>
230 * xdisp.c (forward_to_next_line_start): Allow to use the
231 no-display-properties-and-no-overlays under bidi display.
232 Set disp_pos in the bidi iterator to avoid searches for display
233 properties and overlays.
235 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
237 * editfns.c (Fset_time_zone_rule): Document relationship with the
240 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
241 the font entity extracted from the cache (Bug#8109).
243 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
245 * composite.c (autocmp_chars): Don't reset point. That is done by
246 restore_point_unwind (Bug#5984).
248 2011-08-07 Juri Linkov <juri@jurta.org>
250 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
251 to show the arg `TIME' instead of `TIMEVAL'.
253 2011-08-06 Eli Zaretskii <eliz@gnu.org>
255 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
256 display property strides EOL and includes a newline, as in
257 longlines-mode. (Bug#9254)
258 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
259 word-wrap under bidirectional display. (Bug#9224)
261 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
262 is non-zero, even if the data buffer is NULL. Fixes a crash in
263 vertical-motion with longlines-mode. (Bug#9254)
265 2011-08-05 Eli Zaretskii <eliz@gnu.org>
267 * bidi.c <bidi_cache_total_alloc>: Now static.
268 (bidi_initialize): Initialize bidi_cache_total_alloc.
270 * xdisp.c (display_line): Release buffer allocated for shelved bidi
273 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
274 amount allocated this far in `bidi_cache_total_alloc'.
275 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
276 non-zero, only free the data buffer without restoring the cache
277 contents. All callers changed.
279 * dispextern.h (bidi_unshelve_cache): Update prototype.
281 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
282 (move_it_in_display_line, move_it_to)
283 (move_it_vertically_backward, move_it_by_lines): Replace the call
284 to xfree to an equivalent call to bidi_unshelve_cache.
285 (move_it_in_display_line_to): Fix logic of returning
286 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
288 2011-08-05 Eli Zaretskii <eliz@gnu.org>
290 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
291 came from a string character with a `cursor' property. (Bug#9229)
293 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
295 * Makefile.in (LIB_PTHREAD): New variable.
296 (LIBES): Add LIB_PTHREAD (Bug#9216).
298 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
299 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
301 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
303 * regex.c (re_iswctype): Remove some redundant boolean
306 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
308 * xterm.c (x_find_topmost_parent): New function.
309 (x_set_frame_alpha): Find topmost parent window with

313 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
315 * callproc.c (Fcall_process): Avoid vfork clobbering
316 the local vars buffer, coding_systems, current_dir.
318 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
320 * keymap.c (Fmake_composed_keymap): Move to subr.el.
322 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
324 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
325 so that it is not optimized away.
327 * xdisp.c (compute_display_string_pos): Remove unused local.
329 2011-08-02 Eli Zaretskii <eliz@gnu.org>
331 Fix slow cursor motion and scrolling in large buffers with
332 selective display, like Org Mode buffers. (Bug#9218)
334 * dispextern.h (struct bidi_it): New member disp_prop_p.
336 * xdisp.c: Remove one-slot cache of display string positions.
337 (compute_display_string_pos): Accept an additional argument
338 DISP_PROP_P; callers changed. Scan at most 5K characters forward
339 for a display string or property. If found, set DISP_PROP_P
342 * bidi.c (bidi_fetch_char): Accept an additional argument
343 DISP_PROP_P, and pass it to compute_display_string_pos.
344 Only handle text covered by a display string if DISP_PROP_P is returned
345 non-zero. All callers of bidi_fetch_char changed.
347 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
349 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
351 2010-12-03 Don March <don@ohspite.net>
353 * keymap.c (Fdefine_key): Fix non-prefix key error message when
354 last character M-[char] is translated to ESC [char] (bug#7541).
356 2011-08-02 Kenichi Handa <handa@m17n.org>
358 * lisp.h (uniprop_table): Extern it.
360 * chartab.c (uniprop_table): Make it non-static.
362 2011-08-01 Eli Zaretskii <eliz@gnu.org>
364 * xdisp.c (forward_to_next_line_start): Accept additional argument
365 BIDI_IT_PREV, and store into it the state of the bidi iterator had
367 (reseat_at_next_visible_line_start): Use the bidi iterator state
368 returned by forward_to_next_line_start to restore the state of
369 it->bidi_it after backing up to previous newline. (Bug#9212)
371 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
373 * regex.c (re_comp): Protoize.
374 (re_exec): Fix return type.
375 (regexec): Fix type of `ret'. (Bug#9203)
377 2011-07-29 Paul Eggert <eggert@cs.ucla.edu>
379 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
380 This is needed if max-image-size is a floating-point number.
382 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
384 * print.c (print_object): Print empty symbol as ##.
386 * lread.c (read1): Read ## as empty symbol.
388 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
390 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
391 setting frame foreground color (Bug#9175).
392 (x_set_background_color): Likewise.
394 * nsmenu.m (-setText): Size tooltip dimensions precisely to
396 (EmacsTooltip -init): Remove bezels and add shadows to
399 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
400 or scroll bar (Bug#8470).
402 * nsfont.m (nsfont_open): Remove assignment to voffset and
403 unnecessary vars hshink, expand, hd, full_height, min_height.
404 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
406 * nsterm.h (nsfont_info): Remove voffset field.
408 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
410 Implement strike-through and overline on NextStep (Bug#8863).
412 * nsfont.m (nsfont_open): Use underline position provided by font,
413 instead of hard-coded value of 2.
414 (nsfont_draw): Call ns_draw_text_decoration instead.
416 * nsterm.h: Add declaration for ns_draw_text_decoration.
418 * nsterm.m (ns_draw_text_decoration): New function for drawing
419 underline, overline, and strike-through.
420 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
421 ns_draw_text_decoration. Change treatment of cursor drawing to
422 accomodate underlining, etc.
424 2011-07-28 Eli Zaretskii <eliz@gnu.org>
426 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
429 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
431 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
432 Without this fix, if a signal arrives just after memory fills up,
433 'malloc' might be invoked reentrantly.
435 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
436 In other words, assume that every image size is allowed, on non-X
437 hosts. This assumption is probably wrong, but it lets Emacs compile.
439 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
441 * regex.c (re_iswctype): Convert return values to boolean.
443 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
445 * xdisp.c (compute_display_string_pos): Don't use cached display
446 string position if the buffer had its restriction changed.
449 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
451 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
453 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
455 Integer signedness and overflow and related fixes. (Bug#9079)
457 * bidi.c: Integer size and overflow fixes.
458 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
459 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
460 (bidi_cache_find_level_change, bidi_cache_ensure_space)
461 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
462 (bidi_find_other_level_edge):
463 Use ptrdiff_t instead of EMACS_INT where either will do.
464 This works better on 32-bit hosts configured --with-wide-int.
465 (bidi_cache_ensure_space): Check for size-calculation overflow.
466 Use % rather than repeated addition, for better worst-case speed.
467 Don't set bidi_cache_size until after xrealloc returns, because it
469 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
470 (bidi_cache_ensure_space): Also check that the bidi cache size
471 does not exceed that of the largest Lisp string or buffer. See Eli
472 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
474 * alloc.c (__malloc_size_t): Remove.
475 All uses replaced by size_t. See Andreas Schwab's note
476 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
478 * image.c: Improve checking for integer overflow.
479 (check_image_size): Assume that f is nonnull, since
480 it is always nonnull in practice. This is one less thing to
481 worry about when checking for integer overflow later.
482 (x_check_image_size): New function, which checks for integer
483 overflow issues inside X.
484 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
485 This removes the need for a memory_full check.
486 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
487 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
488 (xbm_read_bitmap_data): Change locals back to 'int', since
489 their values must fit in 'int'.
490 (xpm_load_image, png_load, tiff_load):
491 Invoke x_create_x_image_and_pixmap earlier,
492 to avoid much needless work if the image is too large.
493 (tiff_load): Treat overly large images as if
494 x_create_x_image_and_pixmap failed, not as malloc failures.
495 (gs_load): Use x_check_image_size.
497 * gtkutil.c: Omit integer casts.
498 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
499 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
501 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
503 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
504 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
505 would wrongly return t on a 64-bit host.
507 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
508 The plain *_OVERFLOW macros run afoul of GCC bug 49705
509 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
510 and therefore cause GCC to emit a bogus diagnostic in some cases.
512 * image.c: Integer signedness and overflow and related fixes.
513 This is not an exhaustive set of fixes, but it's time to
514 record what I've got.
515 (lookup_pixel_color, check_image_size): Remove redundant decls.
516 (check_image_size): Don't assume that arbitrary EMACS_INT values
517 fit in 'int', or that arbitrary 'double' values fit in 'int'.
518 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
519 (tiff_load, imagemagick_load_image):
520 Check for overflow in size calculations.
521 (x_create_x_image_and_pixmap): Remove unnecessary test for
522 xmalloc returning NULL; that can't happen.
523 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
524 (xpm_color_bucket): Use better integer hashing function.
525 (xpm_cache_color): Don't possibly over-allocate memory.
526 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
528 Use ptrdiff_t, not int or size_t, to record sizes.
529 (png_load): Don't assume values greater than 2**31 fit in 'int'.
530 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
531 either works, as we prefer signed integers.
532 (tiff_read_from_memory, tiff_write_from_memory):
533 Return tsize_t, not size_t, since that's what the TIFF API wants.
534 (tiff_read_from_memory): Don't fail simply because the read would
535 go past EOF; instead, return a short read.
536 (tiff_load): Omit no-longer-needed casts.
537 (Fimagemagick_types): Don't assume size fits into 'int'.
539 Improve hashing quality when configured --with-wide-int.
540 * fns.c (hash_string): New function, taken from sxhash_string.
541 Do not discard information about ASCII character case; this
542 discarding is no longer needed.
543 (sxhash-string): Use it. Change sig to match it. Caller changed.
544 * lisp.h: Declare it.
545 * lread.c (hash_string): Remove, since we now use fns.c's version.
546 The fns.c version returns a wider integer if --with-wide-int is
547 specified, so this should help the quality of the hashing a bit.
549 * emacs.c: Integer overflow minor fix.
550 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
551 Define only if GNU_LINUX.
552 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
554 * dispnew.c: Integer signedness and overflow fixes.
555 Remove unnecessary forward decls, that were a maintenance hassle.
556 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
558 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
559 (scrolling_window): Use ptrdiff_t, not int, for byte count.
560 (prepare_desired_row, line_draw_cost):
561 Use int, not unsigned, where either works.
562 (save_current_matrix, restore_current_matrix):
563 Use ptrdiff_t, not size_t, where either works.
564 (init_display): Check for overflow more accurately, and without
565 relying on undefined behavior.
567 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
568 Remove, replacing with the new symbols in lisp.h. All uses changed.
569 * fileio.c (make_temp_name):
570 * filelock.c (lock_file_1, lock_file):
571 * xdisp.c (message_dolog):
572 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
573 Use pMd etc. instead.
574 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
575 replacing the pWIDE etc. symbols removed from editfns.c.
577 * keyboard.h (num_input_events): Now uintmax_t.
578 This is (very slightly) less likely to mess up due to wraparound.
581 * buffer.c: Integer signedness fixes.
582 (alloc_buffer_text, enlarge_buffer_text):
583 Use ptrdiff_t rather than size_t when either will do, as we prefer
586 * alloc.c: Integer signedness and overflow fixes.
587 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
588 (__malloc_size_t): Default to size_t, not to int.
589 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
590 (Fgarbage_collect, mark_object_loop_halt, mark_object):
591 Prefer ptrdiff_t to size_t when either would do, as we prefer
593 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
594 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
595 Now const. Initialize with values that are in range even if char
597 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
598 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
599 These functions do the right thing with sizes > 2**32.
600 (check_depth): Now ptrdiff_t, not int.
601 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
602 Adjust to new way of storing sizes. Check for size overflow bugs
604 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
605 slightly wrong anyway, as it missed one instance of
606 XMALLOC_OVERRUN_CHECK_OVERHEAD.
607 (refill_memory_reserve): Omit needless cast to size_t.
608 (mark_object_loop_halt): Mark as externally visible.
610 * xselect.c: Integer signedness and overflow fixes.
611 (Fx_register_dnd_atom, x_handle_dnd_message):
612 Use ptrdiff_t, not size_t, since we prefer signed.
613 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
614 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
615 x_dnd_atoms_size and x_dnd_atoms_length.
617 * doprnt.c: Prefer signed to unsigned when either works.
621 * xdisp.c (vmessage):
622 Use ptrdiff_t, not size_t, when using or implementing doprnt,
623 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
624 prefer signed arithmetic to avoid comparison confusion.
625 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
628 Assume freestanding C89 headers, string.h, stdlib.h.
629 * data.c, doprnt.c, floatfns.c, print.c:
630 Include float.h unconditionally.
631 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
632 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
633 * regex.c: Likewise for stddef.h, string.h.
634 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
635 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
636 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
637 (STDC_HEADERS): Remove obsolete defines.
638 * sysdep.c: Include limits.h unconditionally.
640 Assume support for memcmp, memcpy, memmove, memset.
641 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
642 * regex.c (memcmp, memcpy):
643 Remove; we assume C89 now.
645 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
646 (__malloc_safe_bcopy): Remove; no longer needed.
648 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
649 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
650 well either way, and we prefer signed to unsigned.
652 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
654 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
655 closes the connection while we're reading (bug#9182).
657 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
659 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
660 are specified (Bug#9168).
662 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
664 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
665 Found by GCC static checking and --with-wide-int on a 32-bit host.
667 2011-07-25 Eli Zaretskii <eliz@gnu.org>
669 * xdisp.c (compute_display_string_pos): Fix logic of caching
670 previous display string position. Initialize cached_prev_pos to
671 -1. Fixes slow-down at the beginning of a buffer.
673 2011-07-24 Eli Zaretskii <eliz@gnu.org>
675 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
676 for attrs[LFACE_FONTSET_INDEX].
678 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
680 * xml.c (parse_region): Remove unused local
681 that was recently introduced.
683 2011-07-23 Eli Zaretskii <eliz@gnu.org>
685 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
686 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
688 * xdisp.c (move_it_in_display_line_to): Record the best matching
689 position for TO_CHARPOS while scanning the line, and restore it on
690 exit if none of the characters scanned was an exact match.
691 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
692 when exact match is impossible due to invisible text, and the
695 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
697 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
700 2011-07-22 Eli Zaretskii <eliz@gnu.org>
702 Fix a significant slow-down of cursor motion with C-n, C-p,
703 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
704 auto-repeat under bidi redisplay in fontified buffers.
705 * xdisp.c (compute_stop_pos_backwards): New function.
706 (next_element_from_buffer): Call compute_stop_pos_backwards to
707 find a suitable prev_stop when we find ourselves before
709 (reseat): Don't look for prev_stop, as that could mean a very long
711 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
712 <cached_disp_overlay_modiff>: Cache for last found display string
714 (compute_display_string_pos): Return the cached position if asked
715 about the same buffer in the same area of character positions, and
716 the buffer wasn't changed since the time the display string
719 2011-07-22 Eli Zaretskii <eliz@gnu.org>
721 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
722 is an integer, which is important for empty lines. (Bug#9149)
724 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
726 * frame.c (Fmodify_frame_parameters): In tty case, update the
727 default face if necessary (Bug#4238).
729 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
731 * editfns.c (Fstring_to_char): No need to explain what a character
732 is in the docstring (Bug#6576).
734 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
736 * xml.c (parse_region): Make sure we always return a tree.
738 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
740 * xml.c (parse_region): If a document contains only comments,
743 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
745 * xml.c (make_dom): Return comments, too.
747 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
750 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
751 and the surrounding thread.
752 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
753 rather than fgets, and retry after EINTR. Otherwise, 'emacs
754 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
756 * s/openbsd.h (BROKEN_SIGIO): Define.
757 * unexelf.c (unexec) [__OpenBSD__]:
758 Don't update the .mdebug section of the Alpha COFF symbol table.
760 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
762 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
765 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
767 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
768 This fixes some race conditions on the permissions of any newly
771 * alloc.c (valid_pointer_p): Use pipe, not open.
772 This fixes some permissions issues when debugging.
774 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
775 If fchown fails to set both uid and gid, try to set just gid,
776 as that is sometimes allowed. Adjust the file's mode to eliminate
777 setuid or setgid bits that are inappropriate if fchown fails.
779 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
781 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
782 to compare Lisp_Objects.
783 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
784 global_gnutls_log_level, don't mistake it for a Lisp_Object.
785 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
787 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
789 * lread.c (read_integer): Unread even EOF character.
790 (read1): Likewise. Properly record start position of symbol.
792 * lread.c (read1): Read `#:' as empty uninterned symbol if no
793 symbol character follows.
795 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
797 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
798 This works around a problem with the previous change to Fcopy_file.
799 Recent glibc declares fchown with __attribute__((warn_unused_result)),
800 and without this change, GCC might complain about discarding
801 fchown's return value.
803 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
805 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
807 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
809 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
811 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
813 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
814 it's used from the C level.
816 * process.c: Use the same condition for POLL_FOR_INPUT in both
817 keyboard.c and process.c (bug#1858).
819 2011-07-09 Lawrence Mitchell <wence@gmx.li>
821 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
822 (Fgnutls_boot): Use it.
824 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
826 * doc.c (Fsubstitute_command_keys): Revert last change.
828 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
830 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
831 quotes the next character, and doesn't affect other longer
832 sequences (bug#8935).
834 * lread.c (syms_of_lread): Clarify that is isn't only
835 `eval-buffer' and `eval-defun' that's affected by
836 `lexical-binding' (bug#8460).
838 2011-07-15 Eli Zaretskii <eliz@gnu.org>
840 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
841 bidi redisplay when a line includes both an image and is

846 Fix minor problems found by static checking.
847 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
848 (elsz): Now a signed constant, not a size_t var. We prefer signed
849 types to unsigned, to avoid integer comparison confusion. Without
850 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
851 "cannot optimize loop, the loop counter may overflow", a symptom
853 * indent.c (Fvertical_motion): Mark locals as initialized.
854 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
856 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
858 * search.c (Fre_search_backward): Mention `case-fold-search' in
859 all the re_search_* functions (bug#8138).
861 * keyboard.c (Fopen_dribble_file): Document when the file is
864 2011-07-14 Eli Zaretskii <eliz@gnu.org>

874 bidi_it->string.schars.
875 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
876 NULL (avoids a crash in bidi_paragraph_init).
877 Initialize itb.string.lstring.
878 (init_iterator): Call bidi_init_it only of a valid
879 buffer position was specified. Initialize paragraph_embedding to
881 (reseat_to_string): Initialize the bidi iterator.
882 (display_string): If we need to ignore text properties of
883 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
884 original value of -1 will not work with bidi.)
885 (compute_display_string_pos): First arg is now struct
886 `text_pos *'; all callers changed. Support display properties on
888 (compute_display_string_end): Support display properties on Lisp
890 (init_iterator, reseat_1, reseat_to_string): Initialize the
891 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
892 when iterating on a string not from display properties).
893 (compute_display_string_pos, compute_display_string_end):
894 Fix calculation of the object to scan. Fixes an error when using
896 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
897 base_level_stop; instead, set base_level_stop to BEGV.
898 Fixes crashes in vertical-motion.
899 (next_element_from_buffer): Improve commentary for when
900 the iterator is before prev_stop.
901 (init_iterator): Initialize bidi_p from the default value of
902 bidi-display-reordering, not from buffer-local value. Use the
903 buffer-local value only if initializing for buffer iteration.
904 (handle_invisible_prop): Support invisible properties on strings
905 that are being bidi-reordered.
906 (set_iterator_to_next): Support bidi reordering of C strings and
908 (next_element_from_string): Support bidi reordering of Lisp

915 (reseat_to_string): Initialize it->bidi_p for strings here.
916 (next_element_from_string, next_element_from_c_string)
917 (next_element_from_buffer): Add xassert's for correspondence
918 between IT's object being iterated and it->bidi_it.string
920 (face_before_or_after_it_pos): Support bidi iteration.
921 (next_element_from_c_string): Handle the case of the first string
922 character that is not the first one in the visual order.
923 (get_visually_first_element): New function, refactored from common
924 parts of next_element_from_buffer, next_element_from_string, and
925 next_element_from_c_string.
926 (tool_bar_lines_needed, redisplay_tool_bar)
927 (display_menu_bar): Force left-to-right direction. Add a FIXME
928 comment for making that be controlled by a user option.
929 (push_it, pop_it): Save and restore the state of the
930 bidi iterator. Save and restore the bidi_p flag.
931 (pop_it): Iterate out of display property for string iteration as
933 (iterate_out_of_display_property): Support iteration over strings.
934 (handle_single_display_spec): Set up it->bidi_it for iteration
935 over a display string, and call bidi_init_it.
936 (handle_single_display_spec, next_overlay_string)
937 (get_overlay_strings_1, push_display_prop): Set up the bidi
938 iterator for displaying display or overlay strings.
939 (forward_to_next_line_start): Don't use the shortcut if
941 (back_to_previous_visible_line_start): If handle_display_prop
942 pushed the iterator stack, restore the internal state of the bidi
943 iterator by calling bidi_pop_it same number of times.
944 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
945 and we are bidi-iterating, don't decrement the iterator position;
946 instead, set the first_elt flag in the bidi iterator, to produce
948 (reseat_1): Remove redundant setting of string_from_display_prop_p.
949 (push_display_prop): xassert that we are iterating a buffer.
950 (push_it, pop_it): Save and restore paragraph_embedding member.

952 (get_overlay_strings_1, reseat_1, reseat_to_string)
953 (push_display_prop): Set up the `unibyte' member of bidi_it.string
954 correctly. Don't assume unibyte strings are not bidi-reordered.
955 (compute_display_string_pos)
956 (compute_display_string_end): Fix handling the case of C string.
957 (push_it, pop_it): Save and restore from_disp_prop_p.

959 from_disp_prop_p flag.
960 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
961 (pop_it): Call iterate_out_of_display_property only if we are
962 popping after iteration over a string that came from a display
963 property. Fix a typo in popping stretch info. Add an assertion
964 for verifying that the iterator position is in sync with the bidi
966 (handle_single_display_spec, get_overlay_strings_1)
967 (push_display_prop): Fix initialization of paragraph direction for
968 string when that of the parent object is not yet determined.
969 (reseat_1): Call bidi_init_it to resync the bidi
970 iterator with IT's position. (Bug#7616)
971 (find_row_edges): If ROW->start.pos gives position
972 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

981 saving a temporary copy of the iterator and restoring it back.
982 (back_to_previous_visible_line_start, reseat_1)
983 (init_iterator): Empty the bidi cache "stack".
984 (move_it_in_display_line_to): If iterator ended up at
985 EOL, but we never saw any buffer positions smaller than
986 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
987 motion in bidi-reordered lines.
988 (move_it_in_display_line_to): Record prev_method and prev_pos
989 immediately before the call to set_iterator_to_next. Fixes cursor
990 motion in bidi-reordered lines with stretch glyphs and strings
991 displayed in margins. (Bug#8133) (Bug#8867)

994 (pos_visible_p): Support positions in bidi-reordered lines.
995 Save and restore bidi cache.

1375 (clone_per_buffer_values): Don't assume that
1376 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
1377 This isn't true in general, and it's particularly not true

1416 Random fixes. E.g., (random) never returned negative values.
1417 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
1418 subseconds part to the entropy, as that's a bit more random.
1419 Prefer signed to unsigned, since the signedness doesn't matter and
1420 in general we prefer signed. When given a limit, use a
1421 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
1422 latter isn't right if USE_2_TAGS_FOR_INTS.
1423 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
1424 not 0..VALMASK. Don't discard "excess" bits that random () returns.

1437 This is more efficient than Ffile_directory_p and avoids a minor race.
1439 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
1441 * buffer.c (Foverlay_put): Say what the return value is
1444 * fileio.c (barf_or_query_if_file_exists): Check first if the file
1445 is a directory before asking whether to use the file name
1447 (barf_or_query_if_file_exists): Make the "File is a directory"
1448 error be more correct.
1450 * fns.c (Frequire): Remove the mention of the .gz files, since
1451 that's installation-specific, but keep the mention of

1569 * eval.c (struct backtrace): Simplify and port the data structure.
1570 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
1571 signed bit field, as this assumption is not portable and it makes
1572 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
1573 "char debug_on_exit : 1" as this is not portable either; instead,
1574 use the portable "unsigned int debug_on_exit : 1". Remove unused

1811 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
1812 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
1813 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
1814 since we're not interested in debugging glyphs with old libraries.
1815 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
1816 GCC 4.6.0's static checking.
1818 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

1858 (x_session_initialize): Do not assume string length fits in int.
1860 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

1909 Use memcpy, not strncpy, where memcpy is what is really wanted.
1910 Don't assume (via atoi) that time_t and pid_t fit in int.
1911 Check for time_t and/or pid_t out of range, e.g., via a network share.
1912 Don't alloca where an auto var works fine.
1914 * fileio.c: Fix some integer overflow issues.
1915 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
1916 Don't assume string length fits in int.
1917 (directory_file_name): Don't assume string length fits in long.
1918 (make_temp_name): Don't assume pid fits in int, or that its print
1919 length is less than 20.
1921 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
1923 * coding.c (make_subsidiaries): Don't assume string length fits in int.
1925 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
1927 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
1928 We prefer signed integers, even for size calculations.
1930 * emacs.c: Don't assume string length fits in 'int'.
1931 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
1932 (main): Don't invoke strlen when not needed.
1934 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
1935 (XD_DEBUG_MESSAGE): Don't waste a byte.
1937 * callproc.c (getenv_internal_1, getenv_internal)
1939 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
1941 * lread.c (invalid_syntax): Omit length argument.
1942 All uses changed. This doesn't fix a bug, but it simplifies the
1943 code away from its former Hollerith-constant appearance, and it's
1944 one less 'int' to worry about when looking at integer-overflow issues.
1945 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
1947 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
1948 This didn't break anything, but it didn't help either.
1949 It's confusing to put a bogus integer in a place where the actual
1950 value does not matter.
1951 (LIST_END_P): Remove unused macro and its bogus comment.
1952 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
1954 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
1955 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
1957 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
1958 We prefer signed types, and the value cannot exceed the EMACS_INT
1959 range anyway (because otherwise the length would not be representable).
1960 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
1961 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
1962 This avoids a GCC warning when WIDE_EMACS_INT.
1964 * indent.c (sane_tab_width): New function.
1965 (current_column, scan_for_column, Findent_to, position_indentation)
1966 (compute_motion): Use it. This is just for clarity.
1967 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
1969 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
1971 * lisp.h (lint_assume): New macro.
1972 * composite.c (composition_gstring_put_cache):
1973 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
1975 * editfns.c, insdel.c:
1976 Omit unnecessary forward decls, to simplify future changes.
1978 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
1980 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
1982 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
1983 Use much-faster test for byte-length change.
1984 Don't assume string byte-length fits in 'int'.
1985 Check that character arg fits in 'int'.
1986 (mapcar1): Declare byte as byte, for clarity.
1988 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
1990 * fns.c (concat): Catch string overflow earlier.
1991 Do not rely on integer wraparound.
1993 * dispextern.h (struct it.overlay_strings_charpos)
1994 (struct it.selective): Now EMACS_INT, not int.
1995 * xdisp.c (forward_to_next_line_start)
1996 (back_to_previous_visible_line_start)
1997 (reseat_at_next_visible_line_start, next_element_from_buffer):
1998 Don't arbitrarily truncate the value of 'selective' to int.
2000 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
2002 * composite.c: Don't truncate sizes to 'int'.
2003 (composition_gstring_p, composition_reseat_it)
2004 (composition_adjust_point): Use EMACS_INT, not int.
2005 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
2006 not EMACS_UINT, for indexes.
2008 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
2010 * buffer.c: Include <verify.h>.
2011 (struct sortvec.priority, struct sortstr.priority):
2012 Now EMACS_INT, not int.
2013 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
2014 (struct sortstr.size, record_overlay_string)
2015 (struct sortstrlist.size, struct sortlist.used):
2016 Don't truncate size to int.
2017 (record_overlay_string): Check for size-calculation overflow.
2018 (init_buffer_once): Check at compile-time, not run-time.
2020 2011-06-22 Jim Meyering <meyering@redhat.com>
2022 Don't leak an XBM-image-sized buffer
2023 * image.c (xbm_load): Free the image buffer after using it.
2025 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
2028 * composite.c (find_automatic_composition): Omit needless 'return 0;'
2029 that Sun C diagnosed.
2030 * fns.c (secure_hash): Fix pointer signedness issue.
2031 * intervals.c (static_offset_intervals): New function.
2032 (offset_intervals): Use it.
2034 2011-06-21 Leo Liu <sdl.web@gmail.com>
2037 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
2040 * fns.c (secure_hash): Rename from crypto_hash_function and change
2041 the first arg to accept symbols.
2042 (Fsecure_hash): New primitive.
2043 (syms_of_fns): New symbols.
2045 2011-06-20 Deniz Dogan <deniz@dogan.se>
2047 * process.c (Fset_process_buffer): Clarify return value in
2050 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
2052 * dispnew.c (add_window_display_history): Use BVAR.
2054 * xdisp.c (debug_method_add): Use BVAR.
2055 (check_window_end, dump_glyph_matrix, dump_glyph)
2056 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
2058 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
2061 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
2062 check till after the cache is created in init_frame_faces.
2064 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
2066 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
2068 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
2070 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
2071 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
2072 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
2074 Improve buffer-overflow checking (Bug#8873).
2075 * fileio.c (Finsert_file_contents):
2076 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
2077 Remove the old (too-loose) buffer overflow checks.
2078 They weren't needed, since make_gap checks for buffer overflow.
2079 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
2080 The old code merely checked for Emacs fixnum overflow, and relied
2081 on undefined (wraparound) behavior. The new code avoids undefined
2082 behavior, and also checks for ptrdiff_t and/or size_t overflow.
2084 * editfns.c (Finsert_char): Don't dump core with very negative counts.
2085 Tune. Don't use wider integers than needed. Don't use alloca.
2086 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
2088 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
2090 * insdel.c, lisp.h (buffer_overflow): New function.
2091 (insert_from_buffer_1, replace_range, replace_range_2):
2092 * insdel.c (make_gap_larger):
2093 * editfns.c (Finsert_char):
2094 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
2096 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
2098 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
2100 Integer overflow and signedness fixes (Bug#8873).
2102 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
2103 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
2105 * fileio.c: Don't assume EMACS_INT fits in off_t.
2106 (emacs_lseek): New static function.
2107 (Finsert_file_contents, Fwrite_region): Use it.
2108 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
2110 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
2112 * fns.c: Don't overflow int when computing a list length.
2113 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
2114 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
2115 truncation on 64-bit hosts. Check for QUIT every
2116 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
2117 faster and is responsive enough.
2118 (Flength): Report an error instead of overflowing an integer.
2119 (Fsafe_length): Return a float if the value is not representable
2120 as a fixnum. This shouldn't happen except in contrived situations.
2121 (Fnthcdr, Fsort): Don't assume list length fits in int.
2122 (Fcopy_sequence): Don't assume vector length fits in int.
2124 * alloc.c: Check that resized vectors' lengths fit in fixnums.
2125 (header_size, word_size): New constants.
2126 (allocate_vectorlike): Don't check size overflow here.
2127 (allocate_vector): Check it here instead, since this is the only
2128 caller of allocate_vectorlike that could cause overflow.
2129 Check that the new vector's length is representable as a fixnum.
2131 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
2132 The previous code was bogus. For example, next_almost_prime (32)
2133 returned 39, which is undesirable as it is a multiple of 3; and
2134 next_almost_prime (24) returned 25, which is a multiple of 5 so
2135 why was the code bothering to check for multiples of 7?
2137 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
2139 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
2141 Variadic C functions now count arguments with ptrdiff_t.
2142 This partly undoes my 2011-03-30 change, which replaced int with size_t.
2143 Back then I didn't know that the Emacs coding style prefers signed int.
2144 Also, in the meantime I found a few more instances where arguments
2145 were being counted with int, which may truncate counts on 64-bit
2146 machines, or EMACS_INT, which may be unnecessarily wide.
2147 * lisp.h (struct Lisp_Subr.function.aMANY)
2148 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
2149 Arg counts are now ptrdiff_t, not size_t.
2150 All variadic functions and their callers changed accordingly.
2151 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
2152 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
2153 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
2154 * callint.c (Fcall_interactively): Check arg count for overflow,
2155 to avoid potential buffer overrun. Use signed char, not 'int',
2156 for 'varies' array, so that we needn't bother to check its size
2157 calculation for overflow.
2158 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
2159 * eval.c (apply_lambda):
2160 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
2161 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
2162 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
2164 * callint.c (Fcall_interactively): Don't use index var as event count.
2166 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
2167 * mem-limits.h (SIZE): Remove; no longer used.
2169 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
2171 Remove unnecessary casts.
2172 * xterm.c (x_term_init):
2173 * xfns.c (x_set_border_pixel):
2174 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
2175 These aren't needed now that we assume ANSI C.
2177 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
2178 It's more likely to cause problems (due to unsigned overflow)
2181 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
2183 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
2185 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
2187 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
2189 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
2191 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
2193 GLYPH_CODE_FACE returns EMACS_INT, not int.
2194 * dispextern.h (merge_faces):
2195 * xfaces.c (merge_faces):
2196 * xdisp.c (get_next_display_element, next_element_from_display_vector):
2197 Don't assume EMACS_INT fits in int.
2199 * character.h (CHAR_VALID_P): Remove unused parameter.
2200 * fontset.c, lisp.h, xdisp.c: All uses changed.
2202 * editfns.c (Ftranslate_region_internal): Omit redundant test.
2204 * fns.c (concat): Minor tuning based on overflow analysis.
2205 This doesn't fix any bugs. Use int to hold character, instead
2206 of constantly refetching from Emacs object. Use XFASTINT, not
2207 XINT, for value known to be a character. Don't bother comparing
2208 a single byte to 0400, as it's always less.
2210 * floatfns.c (Fexpt):
2211 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
2213 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
2216 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
2218 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
2219 Without this fix, on a 64-bit host (aset S 0 4294967386) would
2220 incorrectly succeed when S was a string, because 4294967386 was
2221 truncated before it was used.
2223 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
2224 Otherwise, an out-of-range integer could cause undefined behavior
2227 * composite.c: Use int, not EMACS_INT, for characters.
2228 (fill_gstring_body, composition_compute_stop_pos): Use int, not
2229 EMACS_INT, for values that are known to be in character range.
2230 This doesn't fix any bugs but is the usual style inside Emacs and
2231 may generate better code on 32-bit machines.
2233 Make sure a 64-bit char is never passed to ENCODE_CHAR.
2234 This is for reasons similar to the recent CHAR_STRING fix.
2235 * charset.c (Fencode_char): Check that character arg is actually
2236 a character. Pass an int to ENCODE_CHAR.
2237 * charset.h (ENCODE_CHAR): Verify that the character argument is no
2238 wider than 'int', as a compile-time check to prevent future regressions
2241 * character.c (char_string): Remove unnecessary casts.
2243 Make sure a 64-bit char is never passed to CHAR_STRING.
2244 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
2245 by silently ignoring the top 32 bits, allowing some values
2246 that were far too large to be valid characters.
2247 * character.h: Include <verify.h>.
2248 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
2249 arguments are no wider than unsigned, as a compile-time check
2250 to prevent future regressions in this area.
2252 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
2253 (Fsubst_char_in_region):
2255 * xdisp.c (decode_mode_spec_coding):
2256 Adjust to CHAR_STRING's new requirement.
2257 * editfns.c (Finsert_char, Fsubst_char_in_region):
2258 * fns.c (concat): Check that character args are actually
2259 characters. Without this test, these functions did the wrong
2260 thing with wildly out-of-range values on 64-bit hosts.
2262 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
2263 These casts should not be needed on 32-bit hosts, either.
2264 * keyboard.c (read_char):
2265 * lread.c (Fload): Remove casts to unsigned.
2267 * lisp.h (UNSIGNED_CMP): New macro.
2268 This fixes comparison bugs on 64-bit hosts.
2269 (ASCII_CHAR_P): Use it.
2270 * casefiddle.c (casify_object):
2271 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
2272 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
2273 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
2274 * dispextern.h (FACE_FROM_ID):
2275 * keyboard.c (read_char): Use UNSIGNED_CMP.
2277 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
2278 not to EMACS_INT, to avoid GCC warning.
2280 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
2282 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
2283 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
2284 isn't needed on 32-bit machines.
2286 * buffer.c (Fgenerate_new_buffer_name):
2287 Use EMACS_INT for count, not int.
2288 (advance_to_char_boundary): Return EMACS_INT, not int.
2290 * data.c (Qcompiled_function): Now static.
2292 * window.c (window_body_lines): Now static.
2294 * image.c (gif_load): Rename local to avoid shadowing.
2296 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
2297 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
2298 * alloc.c (make_save_value): Integer argument is now of type
2300 (mark_object): Use ptrdiff_t, not int.
2301 * lisp.h (pD): New macro.
2302 * print.c (print_object): Use it.
2304 * alloc.c: Use EMACS_INT, not int, to count objects.
2305 (total_conses, total_markers, total_symbols, total_vector_size)
2306 (total_free_conses, total_free_markers, total_free_symbols)
2307 (total_free_floats, total_floats, total_free_intervals)
2308 (total_intervals, total_strings, total_free_strings):
2309 Now EMACS_INT, not int. All uses changed.
2310 (Fgarbage_collect): Compute overall total using a double, so that
2311 integer overflow is less likely to be a problem. Check for overflow
2312 when converting back to an integer.
2313 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
2314 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
2315 These were 'int' variables that could overflow on 64-bit hosts;
2316 they were never used, so remove them instead of repairing them.
2317 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
2318 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
2319 Previously, this ceilinged at INT_MAX, but that doesn't work on
2321 (allocate_pseudovector): Don't use EMACS_INT when int would do.
2323 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
2324 (allocate_vectorlike): Check for ptrdiff_t overflow.
2325 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
2326 when a (possibly-narrower) signed value would do just as well.
2327 We prefer using signed arithmetic, to avoid comparison confusion.
2329 * alloc.c: Catch some string size overflows that we were missing.
2330 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
2331 for convenience in STRING_BYTES_MAX.
2332 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
2333 The definition here is exact; the one in lisp.h was approximate.
2334 (allocate_string_data): Check for string overflow. This catches
2335 some instances we weren't catching before. Also, it catches
2336 size_t overflow on (unusual) hosts where SIZE_MAX <= min
2337 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
2338 and ptrdiff_t and EMACS_INT are both 64 bits.
2340 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
2341 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
2342 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
2344 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
2346 * alloc.c (Fmake_string): Check for out-of-range init.
2348 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
2350 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
2352 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
2354 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
2355 xg_get_default_scrollbar_width.
2357 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
2358 (int_gtk_range_get_value): Move to the scroll bar part of the file.
2359 (style_changed_cb): Call update_theme_scrollbar_width and call
2360 x_set_scroll_bar_default_width and xg_frame_set_char_size for
2361 all frames (Bug#8505).
2362 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
2363 Call gtk_window_set_resizable if HAVE_GTK3.
2364 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
2365 and height if HAVE_GTK3 (Bug#8505).
2366 (scroll_bar_width_for_theme): New variable.
2367 (update_theme_scrollbar_width): New function.
2368 (xg_get_default_scrollbar_width): Move code to

2838 (Fwindow_minibuffer_p): Move up in code and simplify.
2839 (Fset_frame_selected_window): Move here from frame.c.
2841 (Fselected_window, select_window, Fselect_window): Move up in
2842 code. Minor doc-string fixes.

2846 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
2847 Do not assume that spare memory exists; that assumption is valid
2848 only if SYSTEM_MALLOC.
2849 (LARGE_REQUEST): New macro, so that the issue of large requests
2850 is separated from the issue of spare memory.
2852 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>

2869 min width by calling x_set_scroll_bar_default_width (Bug#8505).
2871 2011-06-05 Juanma Barranquero <lekktu@gmail.com>
2873 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
2875 2011-06-04 Chong Yidong <cyd@stupidchicken.com>

2881 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
2882 Obey Vx_select_enable_clipboard_manager. Catch errors in
2883 x_clipboard_manager_save (Bug#8779).
2884 (Vx_select_enable_clipboard_manager): New variable.
2885 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
2887 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
2889 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
2891 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2893 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
2894 in the current matrix if keep_current_p is non-zero.

2898 * bidi.c (bidi_level_of_next_char): Fix last change.
2900 2011-06-03 Eli Zaretskii <eliz@gnu.org>
2902 Support bidi reordering of text covered by display properties.
2904 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
2905 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
2906 (bidi_cache_search, bidi_cache_iterator_state)
2907 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
2908 (bidi_level_of_next_char, bidi_move_to_visually_next):
2909 Support character positions inside a run of characters covered by a
2911 (bidi_paragraph_init, bidi_resolve_explicit_1)
2912 (bidi_level_of_next_char): Call bidi_fetch_char and
2913 bidi_fetch_char_advance instead of FETCH_CHAR and
2915 (bidi_init_it): Initialize new members.
2916 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
2918 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
2919 instead of using explicit *_CHAR codes.
2920 (bidi_resolve_explicit, bidi_resolve_weak):
2921 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
2922 bidirectional text is supported only in multibyte buffers.
2923 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
2924 it to initialize the frame_window_p member of struct bidi_it.
2925 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
2926 (bidi_resolve_explicit, bidi_resolve_weak)
2927 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
2928 bidi_it->nchars is non-positive.
2929 (bidi_level_of_next_char): Don't try to lookup the cache for the
2930 next/previous character if nothing is cached there yet, or if we
2931 were just reseat()'ed to a new position.
2933 * xdisp.c (set_cursor_from_row): Set start and stop points
2934 according to the row's direction when priming the loop that looks
2935 for the glyph on which to display cursor.
2936 (single_display_spec_intangible_p): Function deleted.
2937 (display_prop_intangible_p): Reimplement to call
2938 handle_display_spec instead of single_display_spec_intangible_p.
2939 Accept 3 additional arguments needed by handle_display_spec.
2940 This fixes incorrect cursor motion across display property with complex
2941 values: lists, `(when COND...)' forms, etc.
2942 (single_display_spec_string_p): Support property values that are
2943 lists with the argument STRING its top-level element.
2944 (display_prop_string_p): Fix the condition for processing a

2947 last portion of handle_display_prop.
2948 (compute_display_string_pos): Accept additional argument
2949 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
2950 value of a `display' property is a "replacing spec".
2951 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
2952 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
2953 the display property, but just return a value indicating whether
2954 the display property will replace the characters it covers.
2955 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
2956 frame_window_p members of struct bidi_it.
2957 (compute_display_string_pos, compute_display_string_end):
2959 (push_it): Accept second argument POSITION, where pop_it should
2960 jump to continue iteration.
2961 (reseat_1): Initialize bidi_it.disp_pos.
2963 * keyboard.c (adjust_point_for_property): Adjust the call to
2964 display_prop_intangible_p to its new signature.
2966 * dispextern.h (struct bidi_it): New member frame_window_p.
2967 (bidi_init_it): Update prototypes.
2968 (display_prop_intangible_p): Update prototype.
2969 (compute_display_string_pos, compute_display_string_end):
2971 (struct bidi_it): New members nchars and disp_pos. ch_len is now
2974 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
2976 Malloc failure behavior now depends on size of allocation.
2977 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
2978 * lisp.h: Change signatures accordingly.
2979 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
2980 All callers changed. (Bug#8762)
2982 * gnutls.c: Use Emacs's memory allocators.
2983 Without this change, the gnutls library would invoke malloc etc.
2984 directly, which causes problems on non-SYNC_INPUT hosts, and which
2985 runs afoul of improving memory_full behavior. (Bug#8761)
2986 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
2987 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
2988 xfree instead of the default malloc, realloc, free.
2989 (Fgnutls_boot): No need to check for memory allocation failure,
2990 since xmalloc does that for us.
2992 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
2993 * category.c (hash_get_category_set):
2994 * ccl.c (ccl_driver):
2995 * charset.c (Fdefine_charset_internal):
2996 * charset.h (struct charset.hash_index):

3005 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
3006 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
3007 (Fsxhash, Fgethash, Fputhash, Fmaphash):
3008 * image.c (make_image, search_image_cache, lookup_image)
3009 (xpm_put_color_table_h):
3010 * lisp.h (struct Lisp_Hash_Table):
3011 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
3012 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
3013 for hashes and hash indexes, instead of 'unsigned' and 'int'.
3014 * alloc.c (allocate_vectorlike):
3015 Check for overflow in vector size calculations.
3016 * ccl.c (ccl_driver):
3017 Check for overflow when converting EMACS_INT to int.
3018 * fns.c, image.c: Remove unnecessary static decls that would otherwise
3019 need to be updated by these changes.
3020 * fns.c (make_hash_table, maybe_resize_hash_table):
3021 Check for integer overflow with large hash tables.
3022 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
3023 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
3024 (SXHASH_REDUCE): New macro.
3025 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
3026 Use it instead of discarding useful hash info with large hash values.
3027 (sxhash_float): New function.
3028 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
3029 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
3030 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
3031 Rewrite to use FIXNUM_BITS, as this simplifies things.
3032 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
3033 Adjust signatures to match updated version of code.
3034 (consing_since_gc): Now EMACS_INT, since a single hash table can
3035 use more than INT_MAX bytes.
3037 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
3039 Make it possible to build with GCC-4.6+ -O2 -flto.
3041 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
3043 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
3045 * minibuf.c (get_minibuffer, read_minibuf_unwind):
3046 Call minibuffer-inactive-mode.
3048 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
3050 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
3051 Update dependencies.
3053 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3055 * data.c (init_data): Remove code for UTS, this system is not
3058 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3060 Don't force ./temacs to start in terminal mode.
3062 * frame.c (make_initial_frame): Initialize faces in all cases, not
3063 only when CANNOT_DUMP is defined.
3064 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
3066 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3068 * dispnew.c (add_window_display_history): Use const for the string
3069 pointer. Remove declaration, not needed.
3071 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3073 Use 'inline', not 'INLINE'.
3074 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
3075 * alloc.c, fontset.c (INLINE): Remove.
3076 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
3077 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
3078 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
3079 * gmalloc.c (register_heapinfo): Use inline unconditionally.
3080 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
3082 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3084 Make it possible to run ./temacs.
3086 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
3087 syms_of_callproc does the same thing. Remove test for
3088 "initialized", do it in the caller.
3089 * emacs.c (main): Avoid calling set_initial_environment when dumping.
3091 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
3093 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
3094 (read_minibuf): Use get_minibuffer.
3095 (syms_of_minibuf): Use DEFSYM.
3096 (Qmetadata): New var.
3097 * data.c (Qbuffer): Don't make it static.
3098 (syms_of_data): Use DEFSYM.
3100 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3102 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
3103 (CCL_CODE_MIN): New macro.
3105 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
3107 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
3109 * eval.c (Qdebug): Now static.
3110 * lisp.h (Qdebug): Remove decl. This reverts a part of the
3111 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
3112 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
3114 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3116 * image.c: Various fixes to ImageMagick code comments.
3117 (Fimagemagick_types): Doc fix.
3119 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
3121 Minor fixes prompted by GCC 4.6.0 warnings.
3123 * xselect.c (converted_selections, conversion_fail_tag): Now static.
3125 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
3126 (x_clipboard_manager_save_all): Move extern decl to ...
3127 * xterm.h: ... here, so that it can be checked for consistency.
3129 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3131 * xselect.c (x_clipboard_manager_save_frame)
3132 (x_clipboard_manager_save_all): New functions.
3133 (Fx_clipboard_manager_save): Lisp function deleted.
3135 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
3136 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
3138 * xterm.h: Update prototype.
3140 2011-05-28 William Xu <william.xwl@gmail.com>
3142 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
3145 2011-05-28 Jim Meyering <meyering@redhat.com>
3147 Avoid a sign-extension bug in crypto_hash_function.
3148 * fns.c (to_uchar): Define.
3149 (crypto_hash_function): Use it to convert some newly-signed
3150 variables to unsigned, to avoid sign-extension bugs. For example,
3151 without this change, (md5 "truc") would evaluate to
3152 45723a2aff78ff4fff7fff1114760e62 rather than the expected
3153 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
3154 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
3156 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3158 Integer overflow fixes.
3160 * dbusbind.c: Serial number integer overflow fixes.
3161 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
3162 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
3163 to hold a serial number that is too large for a fixnum.
3164 (Fdbus_method_return_internal, Fdbus_method_error_internal):
3165 Check for serial numbers out of range. Decode any serial number
3166 that was so large that it became a float. (Bug#8722)
3168 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
3169 (Fdbus_call_method, Fdbus_call_method_asynchronously):
3170 Use XFASTINT rather than XUINT when numbers are nonnegative.
3171 (xd_append_arg, Fdbus_method_return_internal):
3172 (Fdbus_method_error_internal): Likewise. Also, for unsigned
3173 arguments, check that Lisp number is nonnegative, rather than
3174 silently wrapping negative numbers around. (Bug#8722)
3175 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
3178 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
3180 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
3182 ccl: add integer overflow checks
3183 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
3184 (IN_INT_RANGE): New macros.
3185 (ccl_driver): Use them to check for integer overflow when
3186 decoding a CCL program. Many of the new checks are whether XINT (x)
3187 fits in int; it doesn't always, on 64-bit hosts. The new version
3188 doesn't catch all possible integer overflows, but it's an
3189 improvement. (Bug#8719)
3191 * alloc.c (make_event_array): Use XINT, not XUINT.
3192 There's no need for unsigned here.
3194 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
3195 This follows up to the 2011-05-06 change that substituted uintptr_t
3196 for EMACS_INT. This case wasn't caught back then.
3198 Rework Fformat to avoid integer overflow issues.
3199 * editfns.c: Include <float.h> unconditionally, as it's everywhere
3200 now (part of C89). Include <verify.h>.
3201 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
3202 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
3203 (Fformat): Avoid the prepass trying to compute sizes; it was only
3204 approximate and thus did not catch overflow reliably. Instead, walk
3205 through the format just once, formatting and computing sizes as we go,
3206 checking for integer overflow at every step, and allocating a larger
3207 buffer as needed. Keep track separately whether the format is
3208 multibyte. Keep only the most-recently calculated precision, rather
3209 than them all. Record whether each argument has been converted to
3210 string. Use EMACS_INT, not int, for byte and char and arg counts.
3211 Support field widths and precisions larger than INT_MAX. Avoid
3212 sprintf's undefined behavior with conversion specifications such as %#d
3213 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
3214 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
3215 formatting out-of-range floating point numbers with int
3218 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
3220 * data.c: Avoid integer truncation in expressions involving floats.
3221 * data.c: Include <intprops.h>.
3222 (arith_driver): When there's an integer overflow in an expression
3223 involving floating point, convert the integers to floating point
3224 so that the resulting value does not suffer from catastrophic
3225 integer truncation. For example, on a 64-bit host (* 4
3226 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
3227 Do not rely on undefined behavior after integer overflow.
3229 merge count_size_as_multibyte, parse_str_to_multibyte
3230 * character.c, character.h (count_size_as_multibyte):
3231 Rename from parse_str_to_multibyte; all uses changed.
3232 Check for integer overflow.
3233 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
3234 since it's now a duplicate of the other. This is more of
3235 a character than a buffer op, so better that it's in character.c.
3236 * fns.c, print.c: Adjust to above changes.
3238 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
3240 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
3242 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3244 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3245 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
3246 (x_clipboard_manager_save): Now static.
3247 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
3249 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3250 (crypto_hash_function): Now static.
3251 Fix pointer signedness problems. Avoid unnecessary initializations.
3253 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
3255 * termhooks.h (Vselection_alist): Make it terminal-local.
3257 * terminal.c (create_terminal): Initialize it.
3259 * xselect.c: Support for clipboard managers.
3260 (Vselection_alist): Move to termhooks.h as terminal-local var.
3261 (LOCAL_SELECTION): New macro.
3262 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
3263 (symbol_to_x_atom): Remove gratuitous arg.
3264 (x_handle_selection_request, lisp_data_to_selection_data)
3265 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
3266 (x_own_selection, x_get_local_selection, x_convert_selection):
3267 New arg, specifying work frame. Use terminal-local Vselection_alist.
3268 (some_frame_on_display): Delete unused function.
3269 (Fx_own_selection_internal, Fx_get_selection_internal)
3270 (Fx_disown_selection_internal, Fx_selection_owner_p)
3271 (Fx_selection_exists_p): New optional frame arg.
3272 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
3273 (x_handle_selection_clear): Don't treat other terminals with the
3274 same keyboard specially. Use the terminal-local Vselection_alist.
3275 (x_clear_frame_selections): Use Frun_hook_with_args.
3277 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
3279 * xterm.h: Add support for those atoms.
3281 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
3283 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
3284 (converted_selections, conversion_fail_tag): New global variables.
3285 (x_selection_request_lisp_error): Free the above.
3286 (x_get_local_selection): Remove unnecessary code.
3287 (x_reply_selection_request): Args changed; handle arbitrary array
3288 of converted selections stored in converted_selections.
3289 Separate the XChangeProperty and SelectionNotify steps.
3290 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
3291 (x_convert_selection): New function.
3292 (x_handle_selection_event): Simplify.
3293 (x_get_foreign_selection): Don't ignore incoming requests while
3294 waiting for an answer; this will fail when we implement
3295 SAVE_TARGETS, and seems unnecessary anyway.
3296 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
3297 (Vx_sent_selection_functions): Doc fix.
3299 2011-05-26 Leo Liu <sdl.web@gmail.com>
3301 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
3303 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3305 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
3307 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
3308 for fringe update if it has periodic bitmap.
3309 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
3310 and fringe_bitmap_periodic_p.
3312 * fringe.c (get_fringe_bitmap_data): New function.
3313 (draw_fringe_bitmap_1, update_window_fringes): Use it.
3314 (update_window_fringes): Record periodicity of fringe bitmap in glyph
3315 row. Mark glyph row for fringe update if periodicity changed.
3317 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
3318 for fringe update unless it has periodic bitmap.
3320 2011-05-25 Kenichi Handa <handa@m17n.org>
3322 * xdisp.c (get_next_display_element): Set correct it->face_id for
3323 a static composition.
3325 2011-05-24 Leo Liu <sdl.web@gmail.com>
3328 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
3330 * fns.c (crypto_hash_function, Fsha1): New function.
3331 (Fmd5): Use crypto_hash_function.
3332 (syms_of_fns): Add Ssha1.
3334 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3336 * gnutls.c: Remove unused macros.
3337 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
3338 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
3339 Remove macros that are defined and never used.
3340 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
3342 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3344 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
3345 (Fx_get_selection_internal): Minor cleanup.
3346 (Fx_own_selection_internal): Rename arguments for consistency with
3349 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3351 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
3353 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3355 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
3357 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3359 * dispnew.c (scrolling_window): Don't exclude the case that the
3360 last enabled row in the desired matrix touches the bottom boundary.
3362 2011-05-21 Glenn Morris <rgm@gnu.org>
3364 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
3365 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
3366 and add some more files.
3368 2011-05-20 Eli Zaretskii <eliz@gnu.org>
3370 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
3371 report_file_error introduced by the change from 2011-05-07.
3373 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
3375 * systime.h (Time): Define only if emacs is defined.
3376 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
3377 where the include path doesn't have X11/X.h by default. See
3378 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
3380 2011-05-20 Kenichi Handa <handa@m17n.org>
3382 * composite.c (find_automatic_composition): Fix previous change.
3384 2011-05-20 Glenn Morris <rgm@gnu.org>
3386 * lisp.mk: New file, split from Makefile.in.
3387 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
3388 (shortlisp): Remove.
3389 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
3391 2011-05-19 Glenn Morris <rgm@gnu.org>
3393 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
3394 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
3395 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
3396 (lisp): Set the order to that of loadup.el.
3397 (shortlisp): Make it a copy of $lisp.
3398 (SOME_MACHINE_LISP): Remove.
3399 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
3400 Use just $shortlisp, not $SOME_MACHINE_LISP too.
3402 2011-05-18 Kenichi Handa <handa@m17n.org>
3404 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
3405 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
3406 (find_automatic_composition): Mostly rewrite for efficiency.
3408 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
3410 * makefile.w32-in: Update dependencies.
3412 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
3414 * menu.c: Include limits.h (fixes the MS-Windows build broken by
3415 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
3417 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
3419 Fix some integer overflow issues, such as string length overflow.
3421 * insdel.c (count_size_as_multibyte): Check for string overflow.
3423 * character.c (lisp_string_width): Check for string overflow.
3424 Use EMACS_INT, not int, for string indexes and lengths; in
3425 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
3426 the resulting string length overflows an EMACS_INT; instead,
3427 report a string overflow if no precision given. When checking for
3428 precision exhaustion, use a check that cannot possibly have
3429 integer overflow. (Bug#8675)
3430 * character.h (lisp_string_width): Adjust to new signature.
3432 * alloc.c (string_overflow): New function.
3433 (Fmake_string): Use it. This doesn't change behavior, but saves
3434 a few bytes and will simplify future changes.
3435 * character.c (string_escape_byte8): Likewise.
3436 * lisp.h (string_overflow): New decl.
3438 Fixups, following up to the user-interface timestamp change.
3439 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
3440 for UI timestamps, instead of unsigned long.
3441 * msdos.c (mouse_get_pos): Likewise.
3442 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
3443 * w32gui.h (Time): Define by including "systime.h" rather than by
3444 declaring it ourselves. (Bug#8664)
3446 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
3447 * image.c (clear_image_cache): Likewise.
3449 * term.c (term_mouse_position): Don't assume time_t wraparound.
3451 Be more systematic about user-interface timestamps.
3452 Before, the code sometimes used 'Time', sometimes 'unsigned long',
3453 and sometimes 'EMACS_UINT', to represent these timestamps.
3454 This change causes it to use 'Time' uniformly, as that's what X uses.
3455 This makes the code easier to follow, and makes it easier to catch
3456 integer overflow bugs such as Bug#8664.
3457 * frame.c (Fmouse_position, Fmouse_pixel_position):
3458 Use Time, not unsigned long, for user-interface timestamps.
3459 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
3460 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
3461 * keyboard.h (last_event_timestamp): Likewise.
3462 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
3463 * menu.h (xmenu_show): Likewise.
3464 * term.c (term_mouse_position): Likewise.
3465 * termhooks.h (struct input_event.timestamp): Likewise.
3466 (struct terminal.mouse_position_hook): Likewise.
3467 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
3468 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
3469 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
3470 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
3472 * menu.h, termhooks.h: Include "systime.h", for Time.
3474 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
3475 Don't assume that the difference between two unsigned long values
3476 can fit into an integer. At this point, we know button_down_time
3477 <= event->timestamp, so the difference must be nonnegative, so
3478 there's no need to cast the result if double-click-time is
3479 nonnegative, as it should be; check that it's nonnegative, just in
3480 case. This bug is triggered when events are more than 2**31 ms
3481 apart (about 25 days). (Bug#8664)
3483 * xselect.c (last_event_timestamp): Remove duplicate decl.
3484 (x_own_selection): Remove needless cast to unsigned long.
3486 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
3487 that always fit in int. Use a sentinel instead of a counter, to
3488 avoid a temp and to allay GCC's concerns about possible int overflow.
3489 * frame.h (struct frame): Use int for menu_bar_items_used
3490 instead of EMACS_INT, since it always fits in int.
3492 * menu.c (grow_menu_items): Check for int overflow.
3494 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
3496 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
3497 Before, the code was not consistent. These values cannot exceed
3498 2**31 - 1 so there's no need to make them unsigned.
3499 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
3500 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
3501 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
3503 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
3505 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
3506 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
3507 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
3508 presumably because the widths might not match.
3510 * window.c (size_window): Avoid needless test at loop start.
3512 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
3514 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
3516 2011-05-12 Drew Adams <drew.adams@oracle.com>
3518 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
3520 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3522 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
3523 `width' to `bar_area_x' and `bar_area_width', respectively.
3524 (x_scroll_run): Take account of fringe background extension.
3526 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
3527 Rename local vars `left' and `width' to `bar_area_x' and
3528 `bar_area_width', respectively.
3529 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
3530 background extension.
3532 2011-05-10 Jim Meyering <meyering@redhat.com>
3534 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
3536 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
3538 * image.c (Finit_image_library): Return t for built-in image types,
3539 like pbm and xbm. (Bug#8640)
3541 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
3543 * w32menu.c (set_frame_menubar): Fix submenu allocation.
3545 2011-05-07 Eli Zaretskii <eliz@gnu.org>
3547 * w32console.c (Fset_screen_color): Doc fix.
3548 (Fget_screen_color): New function.
3549 (syms_of_ntterm): Defsubr it.
3551 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
3552 unlink the temporary file if Fcall_process didn't create it in the
3554 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
3555 child process will be redirected to a file specified with `:file'.
3556 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
3557 cue to call_process_cleanup not to close that handle.
3559 2011-05-07 Ben Key <bkey76@gmail.com>
3561 * makefile.w32-in: The bootstrap-temacs rule now makes use of
3562 one of two shell specific rules, either bootstrap-temacs-CMD or
3563 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
3564 to the previous implementation of the bootstrap-temacs rule.
3565 The bootstrap-temacs-CMD rule is similar to the previous
3566 implementation of the bootstrap-temacs rule except that it
3567 makes use of the ESC_CFLAGS variable instead of the CFLAGS
3570 These changes, along with some changes to nt/configure.bat,
3571 nt/gmake.defs, and nt/nmake.defs, are required to extend my
3572 earlier fix to add support for --cflags and --ldflags options
3573 that include quotes so that it works whether make uses cmd or
3576 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
3578 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
3579 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
3581 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
3582 a string. Handle both cases.
3583 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
3584 (Fdbus_register_method): Use Qinvalid_function.
3586 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3588 * makefile.w32-in: Update dependencies.
3589 (LISP_H): Add inttypes.h and stdin.h.
3590 (PROCESS_H): Add unistd.h.
3592 2011-05-06 Eli Zaretskii <eliz@gnu.org>
3594 * lread.c: Include limits.h (fixes the MS-Windows build broken by
3595 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
3597 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
3599 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
3601 * term.c (vfatal): Remove stray call to va_end.
3602 It's not needed and the C Standard doesn't allow it here anyway.
3604 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
3605 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
3607 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
3610 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
3612 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3614 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
3616 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
3618 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
3620 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
3621 * charset.c (Fdefine_charset_internal): Don't initialize
3622 charset.code_space[15]. The value was garbage, on hosts with
3623 32-bit int (Bug#8600).
3625 * lread.c (read_integer): Be more consistent with string-to-number.
3626 Use string_to_number to do the actual conversion; this avoids
3627 rounding errors and fixes some other screwups. Without this fix,
3628 for example, #x1fffffffffffffff was misread as -2305843009213693952.
3629 (digit_to_number): Move earlier, for benefit of read_integer.
3630 Return -1 if the digit is out of range for the base, -2 if it is
3631 not a digit in any supported base. (Bug#8602)
3633 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
3635 * dispnew.c (scrolling_window): Return 1 if we scrolled,
3636 to match comment at start of function. This also removes a
3637 GCC warning about overflow in a 32+64-bit port.
3639 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
3641 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
3642 Reported by Stefan Monnier in
3643 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
3644 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3645 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
3647 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
3648 (EMACS_UINTPTR): Likewise, with uintptr_t.
3650 * lisp.h: Prefer 64-bit EMACS_INT if available.
3651 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
3652 on 32-bit hosts that have 64-bit int, so that they can access
3654 However, temporarily disable this change unless the temporary
3655 symbol WIDE_EMACS_INT is defined.
3657 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
3659 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
3660 This removes an assumption that EMACS_INT and long are the same
3661 width as pointers. The assumption is true for Emacs porting targets
3662 now, but we want to make other targets possible.
3663 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
3664 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
3665 In the rest of the code, change types of integers that hold casted
3666 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
3667 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
3668 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
3669 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
3670 No need to cast type when ORing.
3671 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
3672 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
3673 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
3674 assume EMACS_INT is the same width as char *.
3675 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
3676 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
3677 Remove no-longer-needed casts.
3678 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
3679 (xg_tool_bar_help_callback, xg_make_tool_item):
3680 Use EMACS_INTPTR to hold an integer
3681 that will be cast to void *; this can avoid a GCC warning
3682 if EMACS_INT is not the same width as void *.
3683 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
3684 * xdisp.c (display_echo_area_1, resize_mini_window_1):
3685 (current_message_1, set_message_1):
3686 Use a local to convert to proper width without a cast.
3687 * xmenu.c (dialog_selection_callback): Likewise.
3689 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
3690 Also, don't assume VALBITS / RAND_BITS is less than 5,
3691 and don't rely on undefined behavior when shifting a 1 left into
3693 * lisp.h (get_random): Change signature to match.
3695 * lread.c (hash_string): Use size_t, not int, for hash computation.
3696 Normally we prefer signed values; but hashing is special, because
3697 it's better to use unsigned division on hash table sizes so that
3698 the remainder is nonnegative. Also, size_t is the natural width
3699 for hashing into memory. The previous code used 'int', which doesn't
3700 retain enough info to hash well into very large tables.
3701 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
3703 * dbusbind.c: Don't possibly lose pointer info when converting.
3704 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3705 Use XPNTR rather than XHASH, so that the high-order bits of
3706 the pointer aren't lost when converting through void *.
3708 * eval.c (Fautoload): Don't double-shift a pointer.
3710 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
3712 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3714 * gnutls.c (DEF_GNUTLS_FN):
3715 * image.c (DEF_IMGLIB_FN): Make function pointers static.
3717 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
3719 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
3722 2011-05-05 Eli Zaretskii <eliz@gnu.org>
3724 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
3725 New version that can reserve upto 2GB of heap space.
3727 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
3729 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
3731 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
3733 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
3734 `gnutls_certificate_set_x509_key_file'.
3736 2011-05-05 Juanma Barranquero <lekktu@gmail.com>

3842 (Fcall_process_region): Ditto.
3844 2011-04-30 Eli Zaretskii <eliz@gnu.org>
3846 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
3847 rather than `XVECTOR (FOO)->size'.
3849 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
3850 inttypes.h, as a gnulib replacement is used if it not available in

3860 will grow beyond MOST_POSITIVE_FIXNUM.
3861 (decode_coding_emacs_mule): Abort if there isn't enough place in
3862 charbuf for the composition carryover bytes. Reserve an extra
3863 space for up to 2 characters produced in a loop.
3864 (decode_coding_iso_2022): Abort if there isn't enough place in
3865 charbuf for the composition carryover bytes.
3867 2011-04-21 Eli Zaretskii <eliz@gnu.org>

3870 aborting when %lld or %lll format is passed.
3871 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
3872 %llo or %llx format is passed. (Bug#8545)
3874 * window.c (window_scroll_line_based): Use a marker instead of
3875 simple variables to record original value of point. (Bug#7952)
3877 * doprnt.c (doprnt): Fix the case where a multibyte sequence
3878 produced by %s or %c overflows available buffer space. (Bug#8545)
3880 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
3882 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
3883 (SIZE_MAX): Move defn after all includes, as they might #define it.
3885 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3887 * w32.c (init_environment): Warn about defaulting HOME to C:\.
3889 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3891 * keyboard.c (Qdelayed_warnings_hook): Define.
3892 (command_loop_1): Run `delayed-warnings-hook'
3893 if Vdelayed_warnings_list is non-nil.
3894 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.

3897 2011-04-28 Eli Zaretskii <eliz@gnu.org>
3899 * doprnt.c (doprnt): Don't return value smaller than the buffer
3900 size if the message was truncated. (Bug#8545).
3902 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3904 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
3905 (Fx_window_property): #if-0 the whole functions, not just the bodies.
3907 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3909 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
3911 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
3913 * makefile.w32-in: Update dependencies.
3915 2011-04-27 Eli Zaretskii <eliz@gnu.org>
3917 Improve `doprnt' and its usage. (Bug#8545)
3918 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
3919 `format_end'. Remove support for %l as a conversion specifier.
3920 Don't use xrealloc. Improve diagnostics when the %l size modifier
3921 is used. Update the commentary.
3923 * eval.c (verror): Simplify calculation of size_t.
3925 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
3928 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
3930 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
3933 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3935 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
3936 This makes this file independent of the recent pseudovector change.
3938 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
3940 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
3942 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
3943 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
3944 Remove unused local.
3945 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
3947 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
3948 GCC 4.6.0 optimizes based on type-based alias analysis.
3949 For example, if b is of type struct buffer * and v of type struct
3950 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
3951 != &v->size, and therefore "v->size = 1; b->size = 2; return
3952 v->size;" must therefore return 1. This assumption is incorrect
3953 for Emacs, since it type-puns struct Lisp_Vector * with many other
3954 types. To fix this problem, this patch adds a new type struct
3955 vectorlike_header that documents the constraints on layout of vectors
3956 and pseudovectors, and helps optimizing compilers not get fooled
3957 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
3958 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
3959 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
3961 (XSETPVECTYPE): Rewrite in terms of new macro.
3962 (XSETPVECTYPESIZE): New macro, specifying both type and size.
3963 This is a bit clearer, and further avoids the possibility of
3964 undesirable aliasing.
3965 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
3966 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
3967 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
3968 since Lisp_Subr is a special case (no "next" field).
3969 (ASIZE): Now uses header.size rather than size.
3970 All previous uses of XVECTOR (foo)->size replaced to use this macro,
3971 to avoid the hassle of writing XVECTOR (foo)->header.size.
3972 (struct vectorlike_header): New type.
3973 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
3974 object, to help avoid aliasing.
3975 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
3976 (SUBRP): Likewise, since Lisp_Subr is a special case.
3977 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
3978 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
3979 (struct Lisp_Hash_Table): Combine first two members into a single
3980 struct vectorlike_header member. All uses of "size" and "next" members
3981 changed to be "header.size" and "header.next".
3982 * buffer.h (struct buffer): Likewise.
3983 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
3984 * frame.h (struct frame): Likewise.
3985 * process.h (struct Lisp_Process): Likewise.
3986 * termhooks.h (struct terminal): Likewise.
3987 * window.c (struct save_window_data, struct saved_window): Likewise.
3988 * window.h (struct window): Likewise.
3989 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
3990 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
3991 * buffer.c (init_buffer_once): Likewise.
3992 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
3994 * process.c (Fformat_network_address): Use local var for size,
3997 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
3999 Make the Lisp reader and string-to-float more consistent (Bug#8525)
4000 * data.c (atof): Remove decl; no longer used or needed.
4001 (digit_to_number): Move to lread.c.
4002 (Fstring_to_number): Use new string_to_number function, to be
4003 consistent with how the Lisp reader treats infinities and NaNs.
4004 Do not assume that floating-point numbers represent EMACS_INT
4005 without losing information; this is not true on most 64-bit hosts.
4006 Avoid double-rounding errors, by insisting on integers when
4007 parsing non-base-10 numbers, as the documentation specifies.
4008 * lisp.h (string_to_number): New decl, replacing ...
4009 (isfloat_string): Remove.
4010 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
4011 (read1): Do not accept +. and -. as integers; this
4012 appears to have been a coding error. Similarly, do not accept
4013 strings like +-1e0 as floating point numbers. Do not report
4014 overflow for integer overflows unless the base is not 10 which
4015 means we have no simple and reliable way to continue.
4016 Break out the floating-point parsing into a new
4017 function string_to_number, so that Fstring_to_number parses
4018 floating point numbers consistently with the Lisp reader.
4019 (digit_to_number): Move here from data.c. Make it static inline.
4020 (E_CHAR, EXP_INT): Remove, replacing with ...
4021 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
4022 (string_to_number): New function, replacing isfloat_string.
4023 This function checks for valid syntax and produces the resulting
4024 Lisp float number too. Rework it so that string-to-number
4025 no longer mishandles examples like "1.0e+". Use strtoumax,
4026 so that overflow for non-base-10 numbers is reported only when
4027 there's no portable and simple way to convert to floating point.
4029 * textprop.c (set_text_properties_1): Rewrite for clarity,
4030 and to avoid GCC warning about integer overflow.
4032 * intervals.h (struct interval): Use EMACS_INT for members
4033 where EMACS_UINT might cause problems. See
4034 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
4035 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
4036 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
4038 (offset_intervals): Tell GCC not to worry about length overflow
4039 when negating a negative length.
4041 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
4042 (overrun_check_free): Likewise.
4044 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
4045 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
4048 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4049 (gnutls_make_error): Rename local to avoid shadowing.
4050 (gnutls_emacs_global_deinit): ifdef out; not used.
4051 (Fgnutls_boot): Use const for pointer to readonly storage.
4052 Comment out unused local. Fix pointer signedness problems.
4054 * lread.c (openp): Don't stuff size_t into an 'int'.
4055 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
4056 about possible signed overflow.
4058 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4059 (GDK_KEY_g): Don't define if already defined.
4060 (xg_prepare_tooltip): Avoid pointer signedness problem.
4061 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
4063 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
4064 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
4066 * xfns.c (Fx_window_property): Simplify a bit,
4067 to make a bit faster and to avoid GCC 4.6.0 warning.
4068 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
4070 * fns.c (internal_equal): Don't assume size_t fits in int.
4072 * alloc.c (compact_small_strings): Tighten assertion a little.
4074 Replace pEd with more-general pI, and fix some printf arg casts.
4075 * lisp.h (pI): New macro, generalizing old pEd macro to other
4076 conversion specifiers. For example, use "...%"pI"d..." rather
4077 than "...%"pEd"...".
4078 (pEd): Remove. All uses replaced with similar uses of pI.
4079 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
4080 * alloc.c (check_pure_size): Don't overflow by converting size to int.
4081 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
4082 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
4083 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
4084 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
4085 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
4087 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
4088 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
4089 * print.c (safe_debug_print, print_object): Likewise.
4090 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
4092 Use pI instead of if-then-else-abort. Use %p to avoid casts,
4093 avoiding the 0 flag, which is not portable.
4094 * process.c (Fmake_network_process): Use pI to avoid cast.
4095 * region-cache.c (pp_cache): Likewise.
4096 * xdisp.c (decode_mode_spec): Likewise.
4097 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
4098 behavior on 64-bit hosts with printf arg.
4099 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
4100 (x_stop_queuing_selection_requests): Likewise.
4101 (x_get_window_property): Don't truncate byte count to an 'int'
4104 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
4105 here, since it parses constructs like leading '-' and spaces,
4106 which are not wanted; and it overflows with large numbers.
4107 Instead, simply match F[0-9]+, which is what is wanted anyway.
4109 * alloc.c: Remove unportable assumptions about struct layout.
4110 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
4111 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
4112 (allocate_vectorlike, make_pure_vector): Use the new macros,
4113 plus offsetof, to remove unportable assumptions about struct layout.
4114 These assumptions hold on all porting targets that I know of, but
4115 they are not guaranteed, they're easy to remove, and removing them
4116 makes further changes easier.
4118 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
4119 This doesn't fix a bug but makes the code clearer.
4120 (string_overrun_cookie): Now const. Use initializers that
4121 don't formally overflow signed char, to avoid warnings.
4122 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
4123 can cause Emacs to crash when string overrun checking is enabled.
4124 (allocate_buffer): Don't assume sizeof (struct buffer) is a
4125 multiple of sizeof (EMACS_INT); it need not be, if
4126 alignof(EMACS_INT) < sizeof (EMACS_INT).
4127 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
4129 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
4131 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
4133 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
4135 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
4136 supposed to be handshaking. (Bug#8556)
4137 Reported by Paul Eggert <eggert@cs.ucla.edu>.

4141 * lisp.h (Qdebug): List symbol.
4142 * eval.c (Qdebug): Restore global linkage.
4143 * keyboard.c (debug-on-event): New variable.
4144 (handle_user_signal): Break into debugger when debug-on-event
4145 matches the current signal symbol.
4147 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
4149 * alloc.c (check_sblock, check_string_bytes)
4150 (check_string_free_list): Convert to standard C.
4152 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
4154 * w32.c (emacs_gnutls_push): Fix typo.
4156 2011-04-25 Eli Zaretskii <eliz@gnu.org>
4158 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
4159 "cast to pointer from integer of different size".
4161 Improve doprnt and its use in verror. (Bug#8545)
4162 * doprnt.c (doprnt): Document the set of format control sequences
4163 supported by the function. Use SAFE_ALLOCA instead of always
4166 * eval.c (verror): Don't limit the buffer size at size_max-1, that
4167 is one byte too soon. Don't use xrealloc; instead xfree and
4170 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
4172 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
4175 * gnutls.c: Renamed global_initialized to
4176 gnutls_global_initialized. Added internals for the

4709 * fontset.h (face_suitable_for_char_p): Remove decl.
4710 * xfaces.c (face_at_string_position):
4711 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
4712 since 0 is always ASCII.
4714 * fns.c (weak_hash_tables): Now static.
4716 * fileio.c: Make symbols static if they're not exported.
4717 (auto_saving, auto_save_mode_bits, auto_save_error_occurred):

4735 * editfns.c, lisp.h (get_operating_system_release): Remove.
4736 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
4737 worth the hassle of breaking this out.

4846 so that it's not optimized away.
4847 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
4848 * dispextern.h (bidi_dump_cached_states): Remove, since it's
4849 exported only to the debugger.

4852 * atimer.h (run_all_atimers): Remove; not exported.
4854 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.

4856 was inaccessible from Lisp.
4857 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
4858 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.

4878 * xdisp.c (message_enable_multibyte): Now static.
4880 Declare Lisp_Object Q* variables to be 'static' if not exported.
4881 This makes it easier for human readers (and static analyzers)
4882 to see whether these variables are used from other modules.
4883 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
4884 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

4893 Remove decls of unexported vars.
4894 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
4896 * lisp.h (DEFINE_FUNC): Make sname 'static'.
4898 Make Emacs functions such as Fatom 'static' by default.
4899 This makes it easier for human readers (and static analyzers)
4900 to see whether these functions can be called from other modules.
4901 DEFUN now defines a static function. To make the function external
4902 so that it can be used in other C modules, use the new macro DEFUE.

4904 (Finit_image_library):
4905 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

4907 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
4908 Remove decls, since these functions are now static.
4909 (Funintern, Fget_internal_run_time): New decls, since these functions
4910 were already external.
4912 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

4919 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
4920 Mark functions with DEFUE instead of DEFUN,
4921 if they are used in other modules.

4923 decls for now-static functions.
4924 * buffer.h (Fdelete_overlay): Remove decl.

4955 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
4957 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
4960 2011-04-13 Eli Zaretskii <eliz@gnu.org>

4963 when at ZV. (Bug#8487)
4965 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
4967 * charset.c (Fclear_charset_maps): Use xfree instead of free.
4969 * keyboard.c (parse_tool_bar_item): Likewise.
4970 * sound.c (sound_cleanup, alsa_close): Likewise.
4971 * termcap.c (tgetent): Likewise.
4972 * xfns.c (x_default_font_parameter): Likewise.

4976 (overrun_check_free): Protoize.
4978 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
4980 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
4981 since callers should never pass a negative size.
4982 Change the signature to match that of plain 'read' and 'write'; see
4983 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
4984 * lisp.h: Update prototypes of emacs_write and emacs_read.
4986 2011-04-11 Eli Zaretskii <eliz@gnu.org>
4988 * xdisp.c (redisplay_window): Don't try to determine the character
4989 position of the scroll margin if the window start point w->startp
4990 is outside the buffer's accessible region. (Bug#8468)
4992 2011-04-10 Eli Zaretskii <eliz@gnu.org>
4994 Fix write-region and its subroutines for buffers > 2GB.
4995 * fileio.c (a_write, e_write): Modify declaration of arguments and
4996 local variables to support buffers larger than 2GB.
4997 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
4999 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
5000 argument, local variables, and return value.
5002 * lisp.h: Update prototypes of emacs_write and emacs_read.
5004 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
5006 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
5008 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
5010 Fix more problems found by GCC 4.6.0's static checks.
5012 * xdisp.c (vmessage): Use a better test for character truncation.
5014 * charset.c (load_charset_map): <, not <=, for optimization,
5015 and to avoid potential problems with integer overflow.
5016 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
5017 * casetab.c (set_identity, shuffle): Likewise.
5018 * editfns.c (Fformat): Likewise.
5019 * syntax.c (skip_chars): Likewise.
5021 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
5022 This also lets GCC 4.6.0 generate slightly better loop code.
5024 * callint.c (Fcall_interactively): <, not <=, for optimization.
5025 (Fcall_interactively): Count the number of arguments produced,
5026 not the number of arguments given. This is simpler and lets GCC
5027 4.6.0 generate slightly better code.
5029 * ftfont.c: Distingish more carefully between FcChar8 and char.
5030 The previous code passed unsigned char * to a functions like
5031 strlen and xstrcasecmp that expect char *, which does not
5032 conform to the C standard.
5033 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
5034 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
5035 char * when the C standard requires it.
5037 * keyboard.c (read_char): Remove unused var.
5039 * eval.c: Port to Windows vsnprintf (Bug#8435).
5041 (SIZE_MAX): Define if the headers do not.
5042 (verror): Do not give up if vsnprintf returns a negative count.
5043 Instead, grow the buffer. This ports to Windows vsnprintf, which
5044 does not conform to C99. Problem reported by Eli Zaretskii.
5045 Also, simplify the allocation scheme, by avoiding the need for
5046 calling realloc, and removing the ALLOCATED variable.
5048 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
5050 Remove invocations of doprnt, as Emacs now uses vsnprintf.
5051 But keep the doprint source code for now, as we might revamp it
5052 and use it again (Bug#8435).
5053 * lisp.h (doprnt): Remove.
5054 * Makefile.in (base_obj): Remove doprnt.o.
5055 * deps.mk (doprnt.o): Remove.
5057 error: Print 32- and 64-bit integers portably (Bug#8435).
5058 Without this change, on typical 64-bit hosts error ("...%d...", N)
5059 was used to print both 32- and 64-bit integers N, which relied on
5061 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
5063 * lisp.h (error, verror): Mark as printf-like functions.
5064 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
5065 Report overflow in size calculations when allocating printf buffer.
5066 Do not truncate output string at its first null byte.
5067 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
5068 Truncate the output at a character boundary, since vsnprintf does not
5070 * charset.c (check_iso_charset_parameter): Convert internal
5071 character to string before calling 'error', since %c now has the
5073 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
5074 overflow when computing char to be passed to 'error'. Do not
5075 pass Lisp_Object to 'error'; pass the integer instead.
5076 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
5077 formatted with plain %d.
5079 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
5081 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
5083 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
5085 * xterm.c (x_catch_errors): Remove duplicate declaration.
5087 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
5089 * xdisp.c, lisp.h (message_nolog): Remove; unused.
5091 2011-04-10 Jim Meyering <meyering@redhat.com>
5093 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
5094 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
5095 return ssize_t not "int", and use size_t as the buffer length.
5096 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
5097 * gnutls.h: Update declarations.
5098 * process.c (read_process_output): Use ssize_t, to match.
5099 (send_process): Likewise.
5101 2011-04-09 Chong Yidong <cyd@stupidchicken.com>

5141 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
5142 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
5144 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
5145 (encode_invocation_designation): Last argument P_NCHARS is now

5171 instead of using internal_with_output_to_temp_buffer.
5172 (Qhelp_form_show): New var.
5173 (syms_of_keyboard): Use DEFSYM macro.
5175 * print.c (internal_with_output_to_temp_buffer): Function deleted.

5211 * eval.c (Fsignal): Remove excess argument to 'fatal'.
5213 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
5214 This avoids several warnings with gcc -Wstrict-overflow.
5215 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
5216 directly, rather than having caller test rule sign. This avoids
5217 some unnecessary tests.
5218 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
5219 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
5220 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
5222 * xfont.c (xfont_text_extents): Remove var that was set but not used.
5223 (xfont_open): Avoid unnecessary tests.
5225 * composite.c (composition_gstring_put_cache): Use unsigned integer.

5234 by using the new macro.
5236 * textprop.c (set_text_properties_1): Change while to do-while,
5237 since the condition is always true at first.
5239 * intervals.c (graft_intervals_into_buffer): Mark var as used.
5240 (interval_deletion_adjustment): Return unsigned value.
5243 * process.c (list_processes_1, create_pty, read_process_output):

5270 * eval.c (funcall_lambda): Rename local to avoid shadowing.
5272 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
5273 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
5274 can always succeed if overflow has undefined behavior.
5276 * search.c (boyer_moore, wordify): Remove vars set but not used.
5277 (wordify): Omit three unnecessary tests.
5279 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
5280 All callers changed. This avoids the need for an unused var.
5282 * casefiddle.c (casify_region): Remove var that is set but not used.
5284 * dired.c (file_name_completion): Remove var that is set but not used.
5286 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
5288 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
5289 (Finsert_file_contents): Remove unnecessary code checking fd.
5291 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
5292 Check for integer overflow on size calculations.
5294 * buffer.c (Fprevious_overlay_change): Remove var that is set
5297 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
5298 Remove vars that are set but not used.
5299 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
5300 (timer_check_2): Mark vars as initialized.
5302 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
5304 * image.c (lookup_image): Remove var that is set but not used.
5305 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
5307 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
5308 that are set but not used.
5310 * xfns.c (make_invisible_cursor): Don't return garbage
5311 if XCreateBitmapFromData fails (Bug#8410).
5313 * xselect.c (x_get_local_selection, x_handle_property_notify):
5314 Remove vars that are set but not used.
5316 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
5317 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
5319 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
5320 Remove var that is set but not used.
5321 (scroll_bar_windows_size): Now size_t, not int.
5322 (x_send_scroll_bar_event): Use size_t, not int, for sizes.

5326 (map_tty_color) [!defined MSDOS]: Likewise.
5328 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
5330 * coding.c: Remove vars that are set but not used.
5331 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
5332 All callers changed.
5333 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
5334 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
5335 (decode_coding_charset): Remove vars that are set but not used.
5337 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
5338 that is set but not used.
5340 * print.c (print_object): Remove var that is set but not used.
5342 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
5343 The gnulib version avoids calling malloc in the usual case,
5344 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
5345 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
5346 * filelock.c (current_lock_owner): Likewise.
5347 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
5348 * sysdep.c: Include allocator.h, careadlinkat.h.
5349 (emacs_no_realloc_allocator): New static constant.
5350 (emacs_readlink): New function.
5351 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

5356 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
5357 first non-nil return value).
5359 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
5361 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
5362 if not defined (Bug#8403).
5364 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
5366 * xdisp.c (display_count_lines): Remove parameter `start',
5367 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5368 (get_char_face_and_encoding): Remove parameter `multibyte_p',
5369 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

5371 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
5372 and thereabouts. All callers changed.
5373 (get_per_char_metric): Remove parameter `f', unused since
5374 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
5376 2011-04-02 Jim Meyering <meyering@redhat.com>
5378 do not dereference NULL upon failed strdup
5379 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
5380 (ns_get_family): Likewise.
5382 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
5384 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
5386 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
5388 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
5391 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
5393 Add lexical binding.
5395 * window.c (Ftemp_output_buffer_show): New fun.
5396 (Fsave_window_excursion):
5397 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
5399 * lread.c (lisp_file_lexically_bound_p): New function.
5400 (Fload): Bind Qlexical_binding.
5401 (readevalloop): Remove `evalfun' arg.
5402 Bind Qinternal_interpreter_environment.
5403 (Feval_buffer): Bind Qlexical_binding.
5404 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
5406 (syms_of_lread): Declare `lexical-binding'.
5408 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
5410 * keyboard.c (eval_dyn): New fun.
5411 (menu_item_eval_property): Use it.
5413 * image.c (parse_image_spec): Use Ffunctionp.
5415 * fns.c (concat, mapcar1): Accept byte-code-functions.
5417 * eval.c (Fsetq): Handle lexical vars.
5418 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
5419 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
5420 (FletX, Flet): Obey lexical binding.
5421 (Fcommandp): Handle closures.
5422 (Feval): New `lexical' arg.
5423 (eval_sub): New function extracted from Feval. Use it almost
5424 everywhere where Feval was used. Look up vars in lexical env.
5426 (Ffunctionp): Move from subr.el.
5427 (Ffuncall): Handle closures.
5428 (apply_lambda): Remove `eval_flags'.
5429 (funcall_lambda): Handle closures and new byte-code-functions.
5430 (Fspecial_variable_p): New function.
5431 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
5432 but without exporting it to Lisp.
5434 * doc.c (Fdocumentation, store_function_docstring):
5435 * data.c (Finteractive_form): Handle closures.
5437 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
5440 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
5442 (exec_byte_code): New function extracted from Fbyte_code to handle new
5443 calling convention for byte-code-functions. Add new byte-codes.
5445 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
5447 * alloc.c (Fmake_symbol): Init new `declared_special' field.
5449 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
5451 * xdisp.c (redisplay_internal): Fix prototype.
5453 2011-03-31 Eli Zaretskii <eliz@gnu.org>
5455 * xdisp.c (SCROLL_LIMIT): New macro.
5456 (try_scrolling): Use it when setting scroll_limit.
5457 Limit scrolling to 100 screen lines.
5458 (redisplay_window): Even when falling back on "recentering",
5459 position point in the window according to scroll-conservatively,
5460 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
5462 (try_scrolling): When point is above the window, allow searching
5463 as far as scroll_max, or one screenful, to compute vertical
5464 distance from PT to the scroll margin position. This prevents
5465 try_scrolling from unnecessarily failing when
5466 scroll-conservatively is set to a value slightly larger than the
5467 window height. Clean up the case of PT below the margin at bottom
5468 of window: scroll_max can no longer be INT_MAX. When aggressive
5469 scrolling is in use, don't let point enter the opposite scroll
5470 margin as result of the scroll.
5471 (syms_of_xdisp) <scroll-conservatively>: Document the
5472 threshold of 100 lines for never-recentering scrolling.
5474 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
5476 * dispextern.h (move_it_by_lines):
5477 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
5478 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
5479 (message_log_check_duplicate): Remove parameters `prev_bol' and
5480 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5481 (redisplay_internal): Remove parameter `preserve_echo_area',
5482 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
5484 * indent.c (Fvertical_motion):
5485 * window.c (window_scroll_pixel_based, Frecenter):
5486 Don't pass `need_y_p' to `move_it_by_lines'.
5488 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
5490 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
5491 steal a few bits to be more compact.
5492 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
5493 Remove unneeded casts.
5495 * bytecode.c (Fbyte_code): CAR and CDR can GC.
5497 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
5499 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
5500 binding" message (bug#7967).
5502 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
5504 Fix more problems found by GCC 4.6.0's static checks.
5506 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
5507 Remove unused local var.
5509 * editfns.c (Fmessage_box): Remove unused local var.
5511 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
5512 (note_mode_line_or_margin_highlight, note_mouse_highlight):
5513 Omit unused local vars.
5514 * window.c (shrink_windows): Omit unused local var.
5515 * menu.c (digest_single_submenu): Omit unused local var.
5516 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
5517 Omit unused local var.
5519 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
5520 Don't assume string length fits in int.
5521 (keyremap_step, read_key_sequence): Use size_t for sizes.
5522 (read_key_sequence): Don't check last_real_key_start redundantly.
5524 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
5525 instead of alloca (Bug#8344).
5527 * eval.c (Fbacktrace): Don't assume nargs fits in int.
5528 (Fbacktrace_frame): Don't assume nframes fits in int.
5530 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
5532 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
5535 * term.c (produce_glyphless_glyph): Remove unnecessary test.
5537 * cm.c (calccost): Turn while-do into do-while, for clarity.
5539 * keyboard.c (syms_of_keyboard): Use the same style as later
5540 in this function when indexing through an array. This also
5541 works around GCC bug 48267.
5543 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
5545 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
5547 * chartab.c (sub_char_table_ref_and_range): Redo for slight
5548 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
5550 * keyboard.c, keyboard.h (num_input_events): Now size_t.
5551 This avoids undefined behavior on integer overflow, and is a bit
5552 more convenient anyway since it is compared to a size_t variable.
5554 Variadic C functions now count arguments with size_t, not int.
5555 This avoids an unnecessary limitation on 64-bit machines, which
5556 caused (substring ...) to crash on large vectors (Bug#8344).
5557 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
5558 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

5562 * editfns.c (general_insert_function): Likewise.
5563 * eval.c (struct backtrace.nargs, interactive_p)
5564 (internal_condition_case_n, run_hook_with_args, apply_lambda)
5565 (funcall_lambda, mark_backtrace): Likewise.
5566 * fns.c (concat): Likewise.
5567 * frame.c (x_set_frame_parameters): Likewise.
5568 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
5569 0 if not found, not -1. All callers changed.
5571 * alloc.c (garbage_collect): Don't assume stack size fits in int.
5572 (stack_copy_size): Now size_t, not int.
5573 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
5575 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
5577 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
5578 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
5579 All callers changed.

5779 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
5781 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
5782 unconditionnaly since it does the check itself.
5784 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
5786 Fix more problems found by GCC 4.5.2's static checks.
5788 * coding.c (encode_coding_raw_text): Avoid unnecessary test
5789 the first time through the loop, since we know p0 < p1 then.
5790 This also avoids a gcc -Wstrict-overflow warning.
5792 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
5793 leading to a memory leak, possible in functions like
5794 load_charset_map_from_file that can allocate an unbounded number
5795 of objects (Bug#8318).
5797 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
5798 that could (at least in theory) be that large.
5800 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
5801 This is less likely to overflow, and avoids undefined behavior if

5820 * process.c (Fmake_network_process): Use socklen_t, not int,
5821 where POSIX says socklen_t is required in portable programs.
5822 This fixes a porting bug on hosts like 64-bit HP-UX, where
5823 socklen_t is wider than int (Bug#8277).
5824 (Fmake_network_process, server_accept_connection):
5825 (wait_reading_process_output, read_process_output):

5840 Include tparam.h instead, since it declares them.
5841 * cm.h (PC): Remove extern decl; tparam.h now does this.
5842 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
5843 * terminfo.c: Include tparam.h, to check interfaces.
5844 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
5845 (tparam): Adjust signature to match interface in tparam.h;
5846 this removes some undefined behavior. Check that outstring and len
5847 are zero, which they always are with Emacs.
5848 * tparam.h (PC, BC, UP): New extern decls.
5850 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
5851 (xftfont_open): Rename locals to avoid shadowing.

5895 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
5897 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
5899 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
5900 clobbering (Bug#8298).
5901 * sysdep.c (sys_subshell): Likewise.
5902 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
5904 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
5905 This should get cleaned up, so that child_setup has the
5906 same signature on all platforms.
5908 * callproc.c (call_process_cleanup): Now static.
5909 (relocate_fd): Rename locals to avoid shadowing.
5911 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
5913 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
5914 not to be necessary, and produces flickering.

5918 * config.in: Remove file.
5920 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

5971 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
5973 * deps.mk (unexalpha.o): Remove; unused.
5975 New file unexec.h, the (simple) interface for unexec (Bug#8267).

6053 gcc -Wbad-function-cast warning.
6054 (default_value, arithcompare, arith_driver, arith_error): Now static.

6063 (mark_stack): Move local variables into the #ifdef region where
6065 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
6066 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
6068 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.

6077 Use functions, not macros, for up- and down-casing (Bug#8254).
6078 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6079 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
6080 to use the following functions instead of these macros.
6081 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
6082 EMACS_INT, since callers assume the returned value fits in int.
6083 (upcase1): Likewise, for UPCASE_TABLE.
6084 (uppercasep, lowercasep, upcase): New static inline functions.
6085 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

6094 which gcc can warn about.
6095 (regex_compile, re_match_2_internal): Mark locals as initialized.
6096 (RETALLOC_IF): Define only if needed.
6097 (WORDCHAR_P): Likewise. This one is never needed, but is used
6098 only in a comment talking about a compiler bug, so put inside
6099 the #if 0 of that comment.
6100 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
6101 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
6104 * search.c (boyer_moore): Rename locals to avoid shadowing.

6127 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
6128 New macros, so that the caller can use some names other than
6129 gcpro1, gcpro2, etc.
6130 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
6132 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
6133 argument, for consistency with GCPRO2_VAR, etc: it is now the
6134 prefix of the variable, not the variable itself. All uses
6136 * dired.c (directory_files_internal, file_name_completion):
6137 Rename locals to avoid shadowing.
6139 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
6140 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
6141 dired.c's scmp function, had undefined behavior.
6142 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6143 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
6144 * buffer.h: ... to here, because these macros use current_buffer,
6145 and the new implementation with inline functions needs to have
6146 current_buffer in scope now, rather than later when the macros
6148 (downcase, upcase1): New static inline functions.
6149 (DOWNCASE, UPCASE1): Reimplement using these functions.
6150 This avoids undefined behavior in expressions like
6151 DOWNCASE (x) == DOWNCASE (y), which previously suffered
6152 from race conditions in accessing the global variables
6153 case_temp1 and case_temp2.
6154 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
6155 * lisp.h (case_temp1, case_temp2): Remove their decls.
6156 * character.h (ASCII_CHAR_P): Move from here ...
6157 * lisp.h: ... to here, so that the inline functions mentioned
6160 * dired.c (directory_files_internal_unwind): Now static.
6162 * fileio.c (file_name_as_directory, directory_file_name):
6163 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
6165 (file_name_as_directory): Use const pointers when appropriate.
6166 (Fexpand_file_name): Likewise. In particular, newdir might
6167 point at constant storage, so make it a const pointer.
6168 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
6169 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
6171 (Fset_file_times, Finsert_file_contents, auto_save_error):

6180 * lisp.h (verify_bytepos, count_markers): New decls,
6181 so that gcc does not warn that these functions aren't declared.
6183 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
6184 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

6186 (copy_text): Remove unused local var.
6188 * filelock.c (within_one_second): Now static.
6189 (lock_file_1): Rename local to avoid shadowing.
6191 * buffer.c (fix_overlays_before): Mark locals as initialized.
6192 (fix_start_end_in_overlays): Likewise. This function should be
6193 simplified by using pointers-to-pointers, but that's a different
6195 (switch_to_buffer_1): Now static.
6196 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
6197 (report_overlay_modification): Rename locals to avoid shadowing.
6199 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
6200 Fix pointer signedness issue.
6201 (sys_subshell): Mark local as volatile if checking for lint,
6202 to suppress a gcc -Wclobbered warning that does not seem to be right.
6203 (MAXPATHLEN): Define only if needed.
6205 * process.c (serial_open, serial_configure): Move decls from here ...
6206 * systty.h: ... to here, so that they can be checked.
6208 * fns.c (get_random, seed_random): Move extern decls from here ...
6209 * lisp.h: ... to here, so that they can be checked.
6211 * sysdep.c (reset_io): Now static.
6212 (wait_for_termination_signal): Remove; unused.
6214 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
