108
109 2012-07-14 Eli Zaretskii <eliz@gnu.org>
110
111 Remove FILE_SYSTEM_CASE.

133
134 2012-06-26 Andreas Schwab <schwab@linux-m68k.org>
135
136 * gnutls.c (emacs_gnutls_handshake): Only retry if
137 GNUTLS_E_INTERRUPTED.
138
139 2012-06-23 Eli Zaretskii <eliz@gnu.org>
140
141 * ralloc.c (r_alloc_inhibit_buffer_relocation): Fix stupid thinko
142 in the logic of incrementing and decrementing the value of
143 use_relocatable_buffers.
144
145 2012-06-21 Glenn Morris <rgm@gnu.org>
146
147 * charset.c (init_charset): Make lack of etc/charsets fatal.
148

155
156 * Version 24.1 released.
157
158 2012-05-30 Eli Zaretskii <eliz@gnu.org>
159
160 * xdisp.c (handle_stop): Detect whether we have overlay strings
161 loaded by testing it->current.overlay_string_index to be
162 non-negative, instead of checking whether n_overlay_strings is
163 positive. (Bug#11587)
164
165 2012-05-30 Chong Yidong <cyd@gnu.org>
166
167 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

170
171 2012-05-29 Eli Zaretskii <eliz@gnu.org>
172
173 * search.c (search_buffer): Remove calls to
174 r_alloc_inhibit_buffer_relocation, as it is now called by
175 maybe_unify_char, which was the cause of relocation of buffer text
176 in bug#11519.
177
178 2012-05-23 Eli Zaretskii <eliz@gnu.org>
179
180 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
181 for the duration of call to load_charset, to avoid problems with
182 callers of maybe_unify_char that access buffer text through C
183 pointers.
184
185 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
186 decrement the inhibition flag, instead of just setting or
187 resetting it.
188
189 2012-05-24 Ken Brown <kbrown@cornell.edu>
190
191 * callproc.c (Fcall_process): Restore a line that was accidentally
192 commented out in the 2011-02-13 change (bug#11547).

195
196 * lisp.h [REL_ALLOC]: Add prototypes for external functions
197 defined on ralloc.c.
198
199 * buffer.c [REL_ALLOC]: Remove prototypes of
200 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
201 they are now on lisp.h.
202
203 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
204
205 * search.c (search_buffer): Use it to inhibit relocation of buffer
206 text while re_search_2 is doing its job, because re_search_2 is
207 passed C pointers to buffer text. (Bug#11519)
208
209 2012-05-21 Eli Zaretskii <eliz@gnu.org>
210
211 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
212 Update value to 24.
213
214 2012-05-19 Eli Zaretskii <eliz@gnu.org>
215
216 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
217 state after an additional call to move_it_in_display_line_to, keep
218 the values of it->max_ascent and it->max_descent found for the
219 entire line.
220 (pos_visible_p): Revert the comparison against bottom_y to what it
221 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
222 (Bug#11464)
223
224 2012-05-15 Eli Zaretskii <eliz@gnu.org>
225
226 * xdisp.c (pos_visible_p): Fix last change. (Bug#11464)
227
228 2012-05-13 Eli Zaretskii <eliz@gnu.org>
229
230 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
231 already have overlays loaded.
232 (handle_single_display_spec): Before returning without displaying
233 fringe bitmap, synchronize the bidi iterator with the main display
234 iterator, by calling iterate_out_of_display_property.
235 (iterate_out_of_display_property): Detect buffer iteration by
236 testing that it->string is a Lisp string.
237 (get_next_display_element): When the current object is exhausted,
238 and there's something on it->stack, call set_iterator_to_next to
239 proceed with what's on the stack, instead of returning zero.
240 (set_iterator_to_next): If called at the end of a Lisp string,
241 proceed to consider_string_end without incrementing string
242 position. Don't increment display vector index past the end of
243 the display vector. (Bug#11417)
244 (pos_visible_p): Don't report a position visible when move_it_to
245 stopped at the last line of window, which happens to be scanned
246 backwards by the bidi iteration. (Bug#11464)
247
248 2012-05-11 Eli Zaretskii <eliz@gnu.org>
249
250 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
251 and right-margin display specs even if the spec is invalid or we
252 are on a TTY, and thus unable to display on the fringes. That's
253 because the text with the property will not be displayed anyway,
254 so we need to signal to the caller that this is a "replacing"
255 display spec. This fixes display when the spec is invalid or we
256 are on a TTY.
257
258 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
259
260 * unexaix.c (make_hdr): Fix typo in prototype.
261 This bug broke the build on AIX. Problem reported by Gilles Pion.
262
263 2012-05-05 Eli Zaretskii <eliz@gnu.org>
264
265 * w32proc.c (new_child): Force Windows to reserve only 64KB of
266 stack for each reader_thread, instead of defaulting to 8MB
267 determined by the linker. This avoids failures in creating
268 subprocesses on Windows 7, see the discussion in this thread:
269 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
270
271 2012-05-02 Jim Meyering <meyering@redhat.com>
272
273 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
274
275 2012-04-29 Eli Zaretskii <eliz@gnu.org>
276
277 * xdisp.c (pos_visible_p): If already at a newline from the
278 display string before the 'while' loop, don't walk back the glyphs
279 from it3.glyph_row. Solves assertion violation when the display
280 string begins with a newline (egg.el). (Bug#11367)
281
282 2012-04-24 Chong Yidong <cyd@gnu.org>
283
284 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
285
286 2012-04-23 Eli Zaretskii <eliz@gnu.org>
287
288 * xdisp.c (pos_visible_p): If the window start position is beyond
289 ZV, start the display from buffer beginning. Prevents assertion
290 violation in init_iterator when the minibuffer window is scrolled
291 via the scroll bar.
292
293 * window.c (window_scroll_pixel_based): Likewise.
294
295 2012-04-23 Chong Yidong <cyd@gnu.org>
296
297 * keymap.c (where_is_internal): Doc fix (Bug#10872).
298
299 2012-04-20 Glenn Morris <rgm@gnu.org>
300
301 * fileio.c (Fcopy_file, Fset_file_selinux_context):
302 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
303
304 2012-04-20 Eli Zaretskii <eliz@gnu.org>
305
306 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers): Don't
307 overrun array limits of glyph row's used[] array. (Bug#11288)
308
309 2012-04-20 Chong Yidong <cyd@gnu.org>
310
311 * process.c (wait_reading_process_output): If EIO occurs on a pty,
312 set the status to "failed" and ensure that sentinel is run.
313
314 2012-04-18 Glenn Morris <rgm@gnu.org>
315
316 * process.c (Fset_process_inherit_coding_system_flag)
317 (Fset_process_query_on_exit_flag): Doc fix (mention return value).
318 (Fmake_network_process, Fmake_serial_process): Doc fix.
319
320 2012-04-17 Eli Zaretskii <eliz@gnu.org>
321
322 * xdisp.c (string_buffer_position_lim): Limit starting position to
323 BEGV.
324 (set_cursor_from_row): If called for a mode-line or header-line
325 row, return zero immediately.
326 (try_cursor_movement): If inside continuation line, don't back up
327 farther than the first row after the header line, if any. Don't
328 consider the header-line row as "partially visible", even if
329 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
330
331 2012-04-13 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
332
333 * lread.c (lisp_file_lexically_bound_p): Fix hang at ";-*-\n" (bug#11238).
334
335 2012-04-10 Teodor Zlatanov <tzz@lifelogs.com>

338 * process.h: Add integer `gnutls_handshakes_tried' member to
339 process struct.
340
341 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
342 Add convenience `GNUTLS_LOG2i' macro.
343
344 * gnutls.c (gnutls_log_function2i): Convenience log function.
345 (emacs_gnutls_read): Use new log functions,
346 `gnutls_handshakes_tried' process member, and
347 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
348 attempts per process (connection).
349
350 2012-04-09 Eli Zaretskii <eliz@gnu.org>
351
352 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

356
357 * nsterm.m (constrainFrameRect): Always constrain when there is only
358 one screen (Bug#10962).
359
360 2012-04-06 Eli Zaretskii <eliz@gnu.org>
361
362 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
363 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
364 about subtle differences between FETCH_CHAR* and STRING_CHAR*
365 macros related to unification of CJK characters. For the details,
366 see the discussion following the message here:
367 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
368
369 2012-04-04 Chong Yidong <cyd@gnu.org>

382
383 2012-03-31 Eli Zaretskii <eliz@gnu.org>
384
385 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
386 position we get to after a call to move_it_to fails the
387 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
388 only if we wind up in a string from display property. (Bug#11063)
389
390 * window.c (Fdelete_other_windows_internal): Invalidate the row
391 and column information about mouse highlight, so that redisplay
392 restores it after reallocating the glyph matrices. (Bug#7464)
393
394 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
395 string comes from a `display' text property, use the buffer
396 position of that property as if we actually saw that position in
397 the row's glyphs.
398 (move_it_by_lines): Remove the assertion that
399 "it->current_x == 0 && it->hpos == 0" which can be legitimately
400 violated when there's a before-string at the beginning of a line.
401 (Bug#11063)
402
403 2012-03-30 Eli Zaretskii <eliz@gnu.org>
404
405 * xdisp.c (append_space_for_newline): If the default face was
406 remapped, use the remapped face for the appended newline.
407 (extend_face_to_end_of_line): Use the remapped default face for
408 extending the face to the end of the line.
409 (display_line): Call extend_face_to_end_of_line when the default
410 face was remapped. (Bug#11068)
411
412 2012-03-29 Eli Zaretskii <eliz@gnu.org>
413
414 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

431
432 * keyboard.c (Vselection_inhibit_update_commands): New variable.

434 handle-select-window too (Bug#8996).
435
436 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
437

446
447 * s/ms-w32.h (tzname): Include time.h before redirecting to

452 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
453 characters.
454
455 * xterm.c (XTread_socket): Only modify handling_signal if
456 !SYNC_INPUT. (Bug#11080)
457
458 2012-03-23 Eli Zaretskii <eliz@gnu.org>
459
460 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
461 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
462 when fetching a multibyte character consumes more bytes than
463 CHAR_BYTES returns, due to unification of CJK characters in
464 string_char. (Bug#11073)
465
466 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
467

470
471 2012-03-22 Chong Yidong <cyd@gnu.org>
472
473 * dispextern.h (struct it): New member string_from_prefix_prop_p.

476 Mark string as coming from a prefix property.
477 (handle_face_prop): Use default face for prefix strings (Bug#4281).
478 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
479
480 2012-03-21 Chong Yidong <cyd@gnu.org>
481

496
497 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
498 it fit in a valid range (Bug#11003).
499
500 2012-03-18 Eli Zaretskii <eliz@gnu.org>
501
502 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
503 that is not from display property, accept the row as a "cursor
504 row" if one of the string's character has a non-nil `cursor'
505 property. Fixes cursor positioning when there are newlines in
506 overlay strings, e.g. in icomplete.el. (Bug#11035)
507
508 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
509
510 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
511
512 2012-03-12 Chong Yidong <cyd@gnu.org>
513
514 * eval.c (inhibit_lisp_code): Rename from
515 inhibit_window_configuration_change_hook; move from window.c.
516
517 * xfns.c (unwind_create_frame_1, Fx_create_frame):
518 * window.c (run_window_configuration_change_hook)
519 (syms_of_window): Callers changed.

535
536 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
537
538 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
539 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
540 zero (Bug#10954).
541
542 2012-03-03 Glenn Morris <rgm@gnu.org>
543
544 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.

549 position past the first glyph_row that ends at ZV. (Bug#10902)
550 (redisplay_window, next_element_from_string): Fix typos in
551 comments.
552 (redisplay_window): Pass to move_it_vertically the margin in
553 pixels, not in screen lines.
554
555 2012-03-02 Glenn Morris <rgm@gnu.org>
556
557 * buffer.c (buffer-list-update-hook): Doc fix.
558
559 2012-02-29 Eli Zaretskii <eliz@gnu.org>
560
561 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
562 push_it before setting up the iterator for the first overlay
563 string, even if we have an empty string loaded.
564 (next_overlay_string): If there's an empty string on the iterator
565 stack, pop the stack. (Bug#10903)
566
567 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
568
569 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
570 Suggested by Stefan Monnier in
571 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
572 * alloc.c (widen_to_Lisp_Object): New static function.
573 (mark_memory): Also mark Lisp_Objects by fetching pointer words
574 and widening them to Lisp_Objects. This would work even if
575 USE_LSB_TAG is defined and wide integers are used, which might
576 happen in a future version of Emacs.
577
578 2012-02-25 Chong Yidong <cyd@gnu.org>
579
580 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
581 Doc fix.
582
583 * xselect.c (Fx_selection_exists_p): Doc fix.
584 (x_clipboard_manager_save_all): Print an informative message
585 before saving to clipboard manager.
586
587 2012-02-24 Chong Yidong <cyd@gnu.org>
588
589 * keyboard.c (process_special_events): Handle all X selection
590 requests in kbd_buffer, not just the next one (Bug#8869).
591
592 2012-02-23 Chong Yidong <cyd@gnu.org>
593
594 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
595 call when setting menu-bar-lines and tool-bar-lines parameters.
596 (unwind_create_frame_1): New helper function.
597
598 * window.c (inhibit_window_configuration_change_hook): New var.
599 (run_window_configuration_change_hook): Obey it.
600 (syms_of_window): Initialize it.
601
602 2012-02-22 Chong Yidong <cyd@gnu.org>
603
604 * xterm.c (x_draw_image_relief): Add missing type check for
605 Vtool_bar_button_margin (Bug#10743).

608
609 * fileio.c (Vfile_name_handler_alist): Doc fix.

617 when computing $valmask.
618
619 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
620 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
621 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
622 It's useless in that case, and it can cause problems on hosts
623 that allocate halves of EMACS_INT values separately.
624 Reported by Dan Horák. Diagnosed by Andreas Schwab in
625 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
626 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
627 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
628 it avoids undefined behavior on hosts where shifting right by more
629 than the word width has undefined behavior.
630
631 2012-02-19 Chong Yidong <cyd@gnu.org>
632
633 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)

640
641 * .gdbinit (pitx): Fix incorrect references to fields of the
642 iterator stack.
643
644 2012-02-17 Chong Yidong <cyd@gnu.org>
645

647
648 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
649
650 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
651 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
652
653 2012-02-15 Chong Yidong <cyd@gnu.org>
654
655 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

670
671 2012-02-12 Chong Yidong <cyd@gnu.org>
672
673 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
674 as that creates a dangerous corner case.
675
676 * window.c (Fdelete_window_internal): Invalidate the mouse
677 highlight (Bug#9904).
678
679 2012-02-12 Glenn Morris <rgm@gnu.org>
680
681 * xselect.c (Fx_own_selection_internal)
682 (Fx_get_selection_internal, Fx_disown_selection_internal)

685 (Fx_disown_selection_internal, Fx_selection_exists_p)
686 (Fx_selection_owner_p, Fx_get_selection_internal):
687 Sync docs and argument specs with the xselect.c versions.

710
711 * buffer.c (Fbuffer_local_variables)
712 (buffer_lisp_local_variables): Handle unbound vars correctly;

736
737 2012-02-04 Eli Zaretskii <eliz@gnu.org>
738
739 * w32.c (get_emacs_configuration_options):
740 Include --enable-checking, if specified, in the return value.
741
742 2012-02-04 Martin Rudalics <rudalics@gmx.at>
743
744 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
745 after rounding frame sizes. (Bug#9723)

748
749 * keyboard.c (adjust_point_for_property): Don't position point
750 before BEGV. (Bug#10696)
751
752 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
753
754 Handle overflow when computing char display width (Bug#9496).
755 * character.c (char_width): Return EMACS_INT, not int.
756 (char_width, c_string_width): Check for overflow when
757 computing the width; this is possible now that individual
758 characters can have unbounded width. Problem introduced
759 by merge from Emacs 23 on 2012-01-19.
760
761 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
762

780
781 2012-02-02 Kenichi Handa <handa@m17n.org>
782
783 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
784 NULL (Bug#6988).
785 (x_produce_glyphs): If the component of a composition is a null
786 string, set it->pixel_width to 1 to avoid zero-width glyph.
787
788 2012-02-01 Eli Zaretskii <eliz@gnu.org>
789
790 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
791 first 2 arguments are identical. This makes inserting large
792 output from a subprocess an order of magnitude faster on
793 MS-Windows, where all sbrk'ed memory is always contiguous.
794
795 2012-01-31 Glenn Morris <rgm@gnu.org>

840 * process.c (read_process_output): Use p instead of XPROCESS (proc).

864 thrashing the stack of the thread. (Bug#9087)
865
866 2012-01-12 Paul Eggert <eggert@cs.ucla.edu>
867
868 * xdisp.c (rows_from_pos_range): Add parens as per gcc -Wparentheses.
869
870 2012-01-11 Eli Zaretskii <eliz@gnu.org>
871
872 * xdisp.c (rows_from_pos_range): Handle the case where the
873 highlight ends on a newline. (Bug#10464)
874 (mouse_face_from_buffer_pos): Fix off-by-one error in calculating
875 he end column for display of highlight that ends on a newline
876 before a R2L line.
877
878 2012-01-11 Glenn Morris <rgm@gnu.org>
879
880 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs

891
892 * xdisp.c (rows_from_pos_range): Accept additional argument
893 DISP_STRING, and accept any glyph in a row whose object is that
894 string as eligible for mouse highlight. Fixes mouse highlight of
895 display strings from overlays. (Bug#10464)
896
897 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
898
899 emacs: fix an auto-save permissions race condition (Bug#10400)
900 * fileio.c (auto_saving_dir_umask): New static var.
901 (Fmake_directory_internal): Use it.
902 (do_auto_save_make_dir): Set it, instead of invoking chmod after
903 creating the directory. The old code temporarily assigns
904 too-generous permissions to the directory.
905 (do_auto_save_eh): Clear it.
906 (Fdo_auto_save): Catch all errors, not just file errors, so
907 that the var is always cleared.

1408 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
1409 Otherwise, valgrind does not work on some platforms.
1410 Problem reported by Andreas Schwab in
1411 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
1412 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
1413 is set, removing the need for VIRT_ADDRESS_VARIES.
1414 (PURE_P): Use a more-efficient implementation that needs just one
1415 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
1416 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
1417 to 4 (xorl, subq, cmpq, setbe).
1418 * alloc.c (pure): Always extern now, since that's the
1419 VIRT_ADDR_VARIES behavior.
1420 (PURE_POINTER_P): Use a single comparison, not two, for
1421 consistency with the new puresize.h.
1422 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
1423 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

1429 (erase_phys_cursor, update_window_cursor, show_mouse_face)
1430 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
1431 behave as if the cursor position were at the window margin.
1432
1433 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
1434 and the cursor position is out of bounds, behave as if the cursor
1435 position were at the window margin. (Bug#10075)
1436
1437 2011-11-18 Chong Yidong <cyd@gnu.org>
1438
1439 * window.c (Fwindow_combination_limit): Make first argument
1440 non-optional, since it is meaningless for live windows like the
1441 selected window.

1443 2011-11-18 Dmitry Antipov <dmantipov@yandex.ru>
1444
1445 * keymap.c (Fwhere_is_internal): Add missing RETURN_UNGCPROs.

1455 hash values of the two rows.
1456 (copy_row_except_pointers): Preserve the used[] arrays and the
1457 hash values of the two rows. (Bug#10035)
1458 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
1459
1460 * xdisp.c (row_hash): New function, body extracted from
1461 compute_line_metrics.
1462 (compute_line_metrics): Call row_hash, instead of computing the
1463 hash code inline.
1464
1465 * dispnew.c (verify_row_hash): Call row_hash for computing the
1466 hash code of a row, instead of duplicating code from xdisp.c.
1467
1468 * dispextern.h (row_hash): Add prototype.

1505
1506 2011-11-14 Eli Zaretskii <eliz@gnu.org>
1507
1508 * xdisp.c (display_line): Move the call to
1509 highlight_trailing_whitespace before the call to
1510 compute_line_metrics, since the latter needs to see the final
1511 faces of all the glyphs to compute ROW's hash value.
1512 Fixes assertion violations in row_equal_p. (Bug#10035)
1513
1514 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
1515
1516 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
1517 just return (bug#10044).
1518
1519 2011-11-12 Eli Zaretskii <eliz@gnu.org>
1520
1521 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
1522 with user-defined heap size. Bump the default size of the temacs
1523 heap to 27MB, to avoid memory warning when running temacs.
1524 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
1525
1526 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
1527 current_matrix and desired_matrix. (Bug#9990)
1528 (verify_row_hash) [XASSERTS]: New function.
1529 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
1530 that the hash value of glyph rows is correct.

1575 Avoid some portability problems by eschewing 'extern inline' functions.
1576 The trivial performance wins aren't worth the portability hassles; see
1577 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
1578 et seq.
1579 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

1605
1606 2011-11-07 Eli Zaretskii <eliz@gnu.org>
1607
1608 * w32.c (check_windows_init_file): Don't look for term/w32-win.el

1610 of temacs in GUI mode.
1611
1612 2011-11-07 Martin Rudalics <rudalics@gmx.at>
1613

1626
1627 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
1628 This is also needed for porting to any host where GC_MARK_STACK is
1629 not GC_MAKE_GCPROS_NOOPS.
1630 (which_symbols): Use it.
1631
1632 2011-11-07 Kenichi Handa <handa@m17n.org>
1633
1634 * coding.c (coding_set_destination): Check coding->src_pos only
1635 when coding->src_object is a buffer (bug#9910).

1644
1645 * xmenu.c (cleanup_widget_value_tree): New function.
1646 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
1647 calling free_menubar_widget_value_tree directly (Bug#9830).
1648

1653 (window_box_width, window_box_left, window_box_left_offset)
1654 (window_box_right, window_box_right_offset): Declare extern.
1655 Otherwise, these inline functions do not conform to C99 and
1656 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
1657 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
1658 * intervals.c (adjust_intervals_for_insertion)
1659 (adjust_intervals_for_deletion): Now extern, because otherwise the
1660 extern inline functions 'offset_intervals' couldn't refer to it.
1661 (static_offset_intervals): Remove.
1662 (offset_intervals): Rewrite using the old contents of
1663 static_offset_intervals. The old version didn't conform to C99
1664 because an extern inline function contained a reference to an
1665 identifier with static linkage.
1666
1667 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
1668

1685 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
1686 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
1687 (Fwindow_vscroll): Doc fix.
1688 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
1689 argument, since it makes no sense to pass a live window and for
1690 consistency with window-child.
1691

1709 "emacs"-only part.
1710
1711 * w32fns.c (x_create_tip_frame, Fx_create_frame): Rearrange
1712 initialization code to keep similarity to xfns.c after changes
1713 from 2011-11-05.
1714
1715 2011-11-05 Jan Djärv <jan.h.d@swipnet.se>
1716

1718 (unwind_create_frame): New function (Bug#9943).
1719 (Fx_create_frame): Restructure code to be more similar to the one in
1720 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
1721 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
1722 Move terminal->reference_count++ just before making the frame official
1723 (Bug#9943).
1724
1725 * nsterm.m (x_free_frame_resources): New function.
1726 (x_destroy_window): Move code to x_free_frame_resources.
1727
1728 * xfns.c (unwind_create_frame): Fix comment.
1729 (Fx_create_frame, x_create_tip_frame):
1730 Move terminal->reference_count++ just before making the frame
1731 official. Move initialization of image_cache_refcount and
1732 dpyinfo_refcount before calling init_frame_faces (Bug#9943).
1733
1734 2011-11-05 Eli Zaretskii <eliz@gnu.org>
1735
1736 Support MSVC build with newer versions of Visual Studio.
1737 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as

1794
1795 2011-11-01 Eli Zaretskii <eliz@gnu.org>
1796
1797 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
1798 Don't stop backward scan on the continuation glyph, even though

1821 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
1822
1823 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
1824
1825 * xterm.c: Declare x_handle_net_wm_state to return int.
1826 (handle_one_xevent): Check if we are iconified but don't have
1827 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
1828 (get_current_wm_state): Return non-zero if not hidden,
1829 check for _NET_WM_STATE_HIDDEN (Bug#9893).

1835
1836 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
1837 so that this new function doesn't get optimized away by a
1838 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
1839

1868 possible random value that matches one of those tested as
1869 condition to clear the mouse face.
1870

1898 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
1899 New functions.
1900 (w32font_open_internal, compute_metrics):
1901 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
1902 instead of calling the "wide" APIs directly.
1903
1904 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.

1917 * process.c (make_process): Set gnutls_state to NULL.
1918
1919 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
1920 non-NULL, regardless of GNUTLS_INITSTAGE.
1921 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
1922 an error. Set process slots as soon as we allocate them.
1923
1924 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
1925
1926 2011-10-27 Chong Yidong <cyd@gnu.org>

1947
1948 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
1949
1950 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
1951

1965
1966 * bidi.c (bidi_line_init): Initialize the next_en_type member.
1967 (bidi_resolve_explicit_1): When next_en_pos is valid for the
1968 current character, check also for next_en_type being WEAK_EN.
1969 (bidi_resolve_weak): Don't enter the expensive loop if the current
1970 position is before next_en_pos. Record the bidi type of the first
1971 non-ET, non-BN character we find, in addition to its position.
1972 (bidi_level_of_next_char): Invalidate next_en_type when
1973 next_en_pos is over-stepped.
1974
1975 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
1976
1977 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
1978 * editfns.c: Rewrite current-time-zone so that it invokes
1979 the equivalent of (format-time-string "%Z") to get the time zone name.
1980 This fixes a bug when the time zone name contains characters that
1981 need converting from the system time locale to Emacs internal format.
1982 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
1983 that patch fixed format-time-string to do the conversion, but
1984 I forgot to fix current-time-zone.
1985 (format_time_string): New function, containing most of
1986 what Fformat_time_string used to contain.
1987 (Fformat_time_string): Rewrite in terms of format_time_string.
1988 This doesn't change this function's behavior.
1989 (current-time-zone): Rewrite to use format_time_string.
1990 This fixes the bug reported by Michael Schierl in
1991 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
1992 Jason Rumney's 2007-06-07 change worked around this bug, but
1993 didn't fix it.
1994 * systime.h (tzname, timezone): Remove no-longer-used declarations.
1995
1996 2011-10-19 Eli Zaretskii <eliz@gnu.org>
1997
1998 * xdisp.c (start_display): If the character at POS is displayed
1999 via a display vector, reset IT->current.dpvec_index to zero.
2000 (try_window_reusing_current_matrix): If a line ends in a display
2001 vector or the next line starts in a display vector, continue
2002 redrawing the window even though the character position of
2003 start_row was reached.
2004 (Bug#9771, part 2)
2005
2006 2011-10-18 Chong Yidong <cyd@gnu.org>
2007
2008 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
2009 with nobreak-char-display too.
2010
2011 2011-10-18 Eli Zaretskii <eliz@gnu.org>
2012
2013 Fix part 3 of bug#9771.
2014 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
2015 (bidi_resolve_neutral): Don't enter the expensive loop looking for
2016 non-neutral characters if the current character is a paragraph
2017 separator (a.k.a. Newline). This avoids running the same
2018 expensive loop twice, once when we consume the preceding newline
2019 and the other time when the line actually needs to be displayed.
2020 Avoid the loop when we see neutrals on the base embedding level
2021 following a character whose directionality is the same as the
2022 paragraph's. This avoids running the expensive loop when a line
2023 ends in a long sequence of neutrals, like control characters.
2024 Add assertion against STRONG_AL type. Slightly rearrange code
2025 that determines the type of a neutral given the first non-neutral
2026 that follows it.
2027 (bidi_level_of_next_char): Set next_en_pos to zero when
2028 invalidating its info.
2029
2030 2011-10-17 Eli Zaretskii <eliz@gnu.org>
2031
2032 * xdisp.c (push_display_prop): Determine whether to record string
2033 or buffer position by IT->string, not by IT->method. Allow
2034 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
2035 (move_it_vertically_backward): Don't look for character position
2036 immediately after the newline when in a continuation line.
2037 (Bug#9771, part 1)
2038
2039 2011-10-15 Martin Rudalics <rudalics@gmx.at>
2040

2045
2046 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
2047 errors in XSetWindowBorder (bug#9310).
2048
2049 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
2050
2051 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
2052 avoid crash when xmalloc overrun checking is enabled.
2053
2054 2011-10-13 Eli Zaretskii <eliz@gnu.org>
2055
2056 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
2057 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
2058 cursor motion with <left> and <right> arrow keys.
2059
2060 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
2061 some callers set that themselves.
2062
2063 2011-10-12 Eli Zaretskii <eliz@gnu.org>
2064
2065 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
2066 display string and the previous row comes from the same string and
2067 is empty. (Bug#9739) (Bug#9738)
2068
2069 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
2070

2075 * bidi.c (bidi_level_of_next_char):
2076 * xdisp.c (get_visually_first_element): Remove old incorrect
2077 comments regarding the Unicode Line Separator character.
2078
2079 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
2080

2082
2083 * alloc.c (Fgc_status): Do not access beyond zombies array
2084 boundary if nzombies > MAX_ZOMBIES.
2085 * alloc.c (dump_zombies): Add missing format specifier.
2086
2087 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
2088
2089 * xdisp.c (set_cursor_from_row): Simplify conditionals,
2090 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
2091
2092 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
2093 Some packages use them to denote characters with modifiers.
2094
2095 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
2096
2097 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
2098 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
2099 matching a pp-number. Rename parameter var to var1.
2100

2102
2103 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
2104
2105 2011-10-08 Glenn Morris <rgm@gnu.org>
2106
2107 * callint.c (Fcall_interactively): Give a more explicit error for the
2108 'c' case with a non-character input. (Bug#8479)
2109
2110 2011-10-08 Eli Zaretskii <eliz@gnu.org>
2111
2112 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
2113 lines.
2114 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
2115 lines that are hscrolled on the left.
2116

2118 presence of header-line. (Bug#4426)
2119
2120 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
2121
2122 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
2123 Don't advertise functionality which we discourage or doesn't work.
2124
2125 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
2126
2127 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
2128 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
2129 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
2130 this makes Emacs dump core during garbage collection on rare
2131 occasions. sizeof is obviously inferior to offsetof here, so
2132 stick with offsetof.
2133 (GC_POINTER_ALIGNMENT): New macro.
2134 (mark_memory): Omit 3rd (offset) arg; caller changed.
2135 Don't assume EMACS_INT alignment is the same as pointer alignment.
2136
2137 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
2138

2142
2143 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2144
2145 * dired.c (file_name_completion): Don't expand file name.
2146 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
2147 before checking file name handler.
2148
2149 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
2150 they've been requested explicitly (bug#9591).
2151
2152 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
2153
2154 * keymap.c (Fsingle_key_description): Use make_specified_string
2155 instead of build_string to build string from push_key_description.

2159
2160 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
2161 This fixes a Y2038 bug on 64-bit hosts.
2162 * buffer.c (reset_buffer):
2163 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
2164 (Fclear_buffer_auto_save_failure):
2165 Use 0, not -1, to represent an unset failure time, since time_t
2166 might not be signed.
2167
2168 Remove dependency on glibc malloc internals.
2169 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
2170 Move back here from lisp.h, but with their new implementations.
2171 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
2172 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
2173 * charset.c (charset_table_init): New static var.
2174 (syms_of_charset): Use it instead of xmalloc. This removes a
2175 dependency on glibc malloc internals. See Eli Zaretskii's comment in
2176 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
2177 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
2178 Move back to alloc.c.
2179 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
2180 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
2181
2182 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
2183
2184 * nsterm.m (windowDidResize): Call x_set_window_size only when
2185 ns_in_resize is true. Otherwise set pixelwidth/height and
2186 call change_frame_size (Bug#9628).
2187
2188 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
2189
2190 Port --enable-checking=all to Fedora 14 x86-64.
2191 * charset.c (syms_of_charset): Also account for glibc malloc's
2192 internal overhead when calculating the initial malloc maximum.
2193
2194 Port --enable-checking=all to Fedora 14 x86.
2195 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
2196 Move to lisp.h.
2197 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
2198 (overrun_check_realloc, overrun_check_free):
2199 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
2200 That way, xmalloc returns a properly-aligned pointer even if
2201 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
2202 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
2203 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
2204 into account when calculating the initial malloc maximum.
2205 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
2206 Move here from alloc.c, so that charset.c can use it too.
2207 Properly align; the old code wasn't right for common 32-bit hosts
2208 when configured with --enable-checking=all.
2209 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
2210 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
2211
2212 2011-09-29 Eli Zaretskii <eliz@gnu.org>

2215 use EDOM.
2216
2217 2011-09-28 Eli Zaretskii <eliz@gnu.org>
2218
2219 * xdisp.c (compute_display_string_end): If there's no display
2220 string at CHARPOS, return -1.
2221
2222 * bidi.c (bidi_fetch_char): When compute_display_string_end
2223 returns a negative value, treat the character as a normal
2224 character not covered by a display string. (Bug#9624)
2225
2226 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
2227
2228 * lread.c (Fread_from_string): Fix typo in docstring.
2229
2230 2011-09-27 Eli Zaretskii <eliz@gnu.org>
2231
2232 * xdisp.c (handle_invisible_prop): If invisible text ends on a
2233 newline, reseat the iterator instead of bidi-iterating there one
2234 character at a time. (Bug#9610)
2235 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
2236 TO_CHARPOS if the bidi iterator is at base embedding level.
2237
2238 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
2239
2240 * lread.c (readevalloop): Use correct code for NBSP.

2244
2245 * dbusbind.c (Fdbus_register_signal): When service is not
2246 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
2247
2248 2011-09-25 Glenn Morris <rgm@gnu.org>
2249
2250 * buffer.c (truncate-lines): Doc fix.

2266
2267 2011-09-24 Eli Zaretskii <eliz@gnu.org>
2268
2269 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
2270 Default value is now t. Doc fix.
2271
2272 * indent.c (Fvertical_motion): Compute and apply the overshoot
2273 logic when moving up, not only when moving down. Fix the
2274 confusing name and values of the it_overshoot_expected variable;
2275 logic changes accordingly. (Bug#9254) (Bug#9549)
2276
2277 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
2278 CHARPOS is covered by a display string which includes newlines.
2279 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
2280 is covered by a display string with embedded newlines.
2281
2282 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
2283
2284 * dbusbind.c (Fdbus_register_signal): Add match rule to

2289 2011-09-24 Jim Meyering <meyering@redhat.com>
2290
2291 do not ignore write error for any output size
2292 The previous change was incomplete.
2293 While it makes emacs --batch detect the vast majority of stdout
2294 write failures, errors were still ignored whenever the output size is
2295 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
2296 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
2297 && echo FAIL: ignored write error
2298 FAIL: ignored write error
2299 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
2300 && echo FAIL: ignored write error
2301 FAIL: ignored write error
2302 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
2303
2304 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
2305
2306 * emacs.c (Fkill_emacs): In noninteractive mode exit
2307 non-successfully if a write error occurred on stdout. (Bug#9574)
2308
2309 2011-09-21 Eli Zaretskii <eliz@gnu.org>
2310
2311 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
2312 the xassert test.
2313
2314 * dispextern.h (struct it): Update the comment documenting what
2315 can it->OBJECT be.
2316
2317 2011-09-20 Eli Zaretskii <eliz@gnu.org>
2318
2319 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
2320 a display string, extend search for cursor position to end of row.
2321 (find_row_edges): If the row ends in a newline from a display
2322 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
2323 Handle the case of a display string with multiple newlines.
2324 (Fcurrent_bidi_paragraph_direction): Fix search for previous
2325 non-empty line. Fixes confusing cursor motion with arrow keys at
2326 the beginning of a line that starts with whitespace.
2327
2328 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
2329
2330 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is

2335 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
2336 boolean (Bug#9154).
2337
2338 2011-09-18 Eli Zaretskii <eliz@gnu.org>
2339
2340 * xdisp.c (display_line): Record maximum and minimum buffer
2341 positions even if no glyphs were produced (e.g., by a zero-width
2342 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
2343 buffer positions that will be removed from the glyph row because
2344 they don't fit.
2345 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
2346 column is beyond frame width: don't subtract 1 "pixel" when
2347 computing width of the stretch.
2348 (reseat_at_next_visible_line_start): Undo the change made on
2349 2011-09-17 that saved paragraph information and restored it after
2350 the call to `reseat'. (Bug#9545)
2351
2352 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2353
2354 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
2355 and turn window cursor on if cleared (Bug#9415).
2356
2357 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
2358
2359 * search.c (boyer_moore): Take unibyte characters from pattern
2360 literally. (Bug#9458)

2367
2368 Fix minor problem found by static checking.
2369 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
2370 initialized, to pacify gcc -Wuninitialized.
2371
2372 * fileio.c: Report proper errno when syscall falls.
2373 (Finsert_file_contents): Save and restore errno,
2374 so that report_file_error outputs the correct diagnostic.
2375 (Fwrite_region) [CLASH_DETECTION]: Likewise.
2376
2377 2011-09-18 Eli Zaretskii <eliz@gnu.org>

2380
2381 2011-09-17 Eli Zaretskii <eliz@gnu.org>
2382
2383 * xdisp.c (produce_stretch_glyph): Another fix for changes made on

2385
2386 2011-09-17 Eli Zaretskii <eliz@gnu.org>
2387
2388 * xdisp.c (reseat_at_next_visible_line_start): Keep information
2389 about the current paragraph and restore it after the call to reseat.
2390
2391 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
2392 (bidi_find_paragraph_start): Search back for paragraph beginning
2393 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
2394 (bidi_move_to_visually_next): Only trigger paragraph-related
2395 computations when the last character is a newline or at EOB, not
2396 just any NEUTRAL_B. (Bug#9470)
2397
2398 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
2399 truncated lines if point is covered by a display string. (Bug#9524)
2400
2401 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
2402
2403 * xselect.c: Relax test for outgoing X longs (Bug#9498).
2404 (cons_to_x_long): New function.
2405 (lisp_data_to_selection_data): Use it. Correct the test for
2406 short-versus-long data; it was negated. Break out of vector
2407 loop, for efficiency, when a long datum is discovered.
2408
2409 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
2410
2411 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
2412
2413 2011-09-16 Eli Zaretskii <eliz@gnu.org>
2414
2415 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
2416 GCC PR/17406) by declaring this function with external scope.
2417
2418 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
2419
2420 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
2421 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
2422
2423 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
2424
2425 * editfns.c (Fformat): Correctly handle text properties on "%%".

2435 of TAB characters in a composition.
2436
2437 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
2438
2439 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
2440 This occurs when processing a multibyte format.
2441 Problem reported by Wolfgang Jenker.
2442
2443 2011-09-15 Johan Bockgård <bojohan@gnu.org>
2444

2446 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
2447
2448 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
2449
2450 Remove unused external symbols.

2457
2458 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
2459
2460 * xselect.c: Use signed conversions more consistently (Bug#9498).
2461 (selection_data_to_lisp_data): Assume incoming selection data are
2462 signed integers, not unsigned. This is to be consistent with
2463 outgoing selection data, which was modified to use signed integers
2464 in as part of the fix to Bug#9196 in response to Jan D.'s comment
2465 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
2466 expects long, not unsigned long.
2467
2468 2011-09-14 Eli Zaretskii <eliz@gnu.org>
2469
2470 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect

2473
2474 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
2475

2477
2478 2011-09-12 Eli Zaretskii <eliz@gnu.org>
2479
2480 * indent.c (compute_motion): Process display vector front to back
2481 rather than the other way around. (Bug#2496)
2482
2483 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2484
2485 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
2486
2487 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
2488
2489 * minibuf.c (Fread_from_minibuffer): Doc fix.
2490
2491 2011-09-11 Eli Zaretskii <eliz@gnu.org>
2492
2493 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
2494 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
2495
2496 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
2497
2498 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
2499 value for non-existent files.
2500
2501 2011-09-11 Eli Zaretskii <eliz@gnu.org>
2502
2503 * fileio.c (Finsert_file_contents): If the file cannot be opened,
2504 set its "size" to -1. This will set the modtime_size field of
2505 the corresponding buffer to -1, which is what
2506 verify-visited-file-modtime expects for files that do not exist.
2507 (Bug#9139)
2508
2509 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
2510
2511 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
2512 here ...
2513 * lisp.h: ... from here. push_key_description is no longer
2514 defined in keyboard.c, so its declaration should not be in
2515 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
2516 logically belongs with push_key_description.
2517
2518 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
2519
2520 * buffer.h: Include <sys/types.h> instead of <time.h>.
2521 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.

2534 2011-09-10 Eli Zaretskii <eliz@gnu.org>
2535
2536 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
2537 redisplay in small windows.
2538
2539 2011-09-09 Eli Zaretskii <eliz@gnu.org>
2540

2560
2561 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
2562
2563 isnan: Fix porting problem to Solaris 10 with bundled gcc.
2564 Without this fix, the command to link temacs failed due to an
2565 undefined symbol __builtin_isnan. This is because
2566 /usr/include/iso/math_c99.h #defines isnan(x) to
2567 __builtin_isnan(x), but the bundled gcc, which identifies itself
2568 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
2569 a __builtin_isnan.
2570 * floatfns.c (isnan): #undef, and then #define to a clone of
2571 what's in data.c.
2572 (Fisnan): Always define, since it's always available now.
2573 (syms_of_floatfns): Always define isnan at the Lisp level.

2577 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
2578
2579 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
2580
2581 * fileio.c: Fix bugs with large file offsets (Bug#9428).
2582 The previous code assumed that file offsets (off_t values) fit in
2583 EMACS_INT variables, which is not true on typical 32-bit hosts.
2584 The code messed up by falsely reporting buffer overflow in cases
2585 such as (insert-file-contents "big" nil 1 2) into an empty buffer
2586 when "big" contains more than 2**29 bytes, even though this
2587 inserts just one byte and does not overflow the buffer.
2588 (Finsert_file_contents): Store file offsets as off_t
2589 values, not as EMACS_INT values. Check for overflow when
2590 converting between EMACS_INT and off_t. When checking for
2591 buffer overflow or for overlap, take the offsets into account.
2592 Don't use EMACS_INT for small values where int suffices.
2593 When checking for overlap, fix a typo: ZV was used where
2594 ZV_BYTE was intended.
2595 (Fwrite_region): Don't assume off_t fits into 'long'.
2596 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
2597
2598 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
2599
2600 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
2601
2602 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
2603
2604 sprintf-related integer and memory overflow issues (Bug#9412).
2605
2606 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
2607 (esprintf, exprintf, evxprintf): New functions.
2608 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
2609 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
2610 (modify_event_symbol): Do not assume that the length of
2611 name_alist_or_stem is safe to alloca and fits in int.
2612 (Fexecute_extended_command): Likewise for function name and binding.
2613 (Frecursion_depth): Wrap around reliably on integer overflow.
2614 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
2615 since some callers pass EMACS_INT values.
2616 (Fsingle_key_description): Don't crash if symbol name contains more
2617 than MAX_ALLOCA bytes.
2618 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
2619 (get_minibuffer): Arg is now EMACS_INT, not int.
2620 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
2621 (esprintf, exprintf, evxprintf): New decls.
2622 * window.h (command_loop_level, minibuf_level): Reflect API changes.
2623
2624 * dbusbind.c (signature_cat): New function.
2625 (xd_signature, Fdbus_register_signal):
2626 Do not overrun buffer; instead, report string overflow.
2627
2628 * dispnew.c (add_window_display_history): Don't overrun buffer.
2629 Truncate instead; this is OK since it's just a log.
2630
2631 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
2632 even if the time zone offset is outlandishly large.
2633 Don't mishandle offset == INT_MIN.
2634
2635 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
2636 when creating daemon; the previous buffer-overflow check was incorrect.
2637
2638 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
2639 which has the guts of the old verror function.
2640
2641 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
2642 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
2643
2644 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
2645 (font_unparse_xlfd): Don't blindly alloca long strings.
2646 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
2647 fits in int, when using sprintf. Use single snprintf to count
2648 length of string rather than counting it via multiple sprintfs;
2649 that's simpler and more reliable.
2650 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
2651 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
2652 sprintf, in case result does not fit in int.
2653
2654 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
2655 (fontset_from_font): Print it.
2656
2657 * frame.c (tty_frame_count): Now printmax_t, not int.
2658 (make_terminal_frame, set_term_frame_name): Print it.
2659 (x_report_frame_params): In X, window IDs are unsigned long,
2660 not signed long, so print them as unsigned.
2661 (validate_x_resource_name): Check for implausibly long names,
2662 and don't assume name length fits in 'int'.
2663 (x_get_resource_string): Don't blindly alloca invocation name;
2664 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
2665 not fit in int.
2666
2667 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
2668 (xg_check_special_colors, xg_set_geometry):
2669 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
2670
2671 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
2672 Use esprintf, not sprintf, in case result does not fit in int.
2673
2674 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
2675 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
2676 it as a large positive number.
2677 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
2678 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
2679
2680 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
2681 in case result does not fit in int.
2682
2683 * print.c (float_to_string): Detect width overflow more reliably.
2684 (print_object): Make sprintf buffer a bit bigger, to avoid potential
2685 buffer overrun. Don't assume list length fits in 'int'. Treat
2686 print length of 0 as 0, not as infinity; to be consistent with other
2687 uses of print length in this function. Don't overflow print length
2688 index. Don't assume hash table size fits in 'long', or that
2689 vectorlike size fits in 'unsigned long'.
2690
2691 * process.c (make_process): Use printmax_t, not int, to format
2692 process-name gensyms.
2693
2694 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
2695
2696 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
2697 to avoid potential buffer overrun.
2698
2699 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
2700 if X resource line is longer than 512 bytes.
2701
2702 * xfns.c (x_window): Make sprintf buffer a bit bigger
2703 to avoid potential buffer overrun.
2704
2705 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
2706
2707 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
2708
2709 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
2710
2711 Integer overflow fixes for scrolling, etc.
2712 Without these, Emacs silently mishandles large integers sometimes.
2713 For example, "C-u 4294967297 M-x recenter" was treated as if
2714 it were "C-u 1 M-x recenter" on a typical 64-bit host.
2715
2716 * xdisp.c (try_window_id): Check Emacs fixnum range before
2717 converting to 'int'.
2718
2719 * window.c (window_scroll_line_based, Frecenter):
2720 Check that an Emacs fixnum is in range before assigning it to 'int'.
2721 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
2722 values converted from Emacs fixnums.
2723 (Frecenter): Don't wrap around a line count if it is out of 'int'
2724 range; instead, treat it as an extreme value.
2725 (Fset_window_configuration, compare_window_configurations):
2726 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
2727
2728 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
2729 that can exceed INT_MAX. Check that EMACS_INT value is in range
2730 before assigning it to the (possibly-narrower) index.
2731 (match_limit): Don't assume that a fixnum can fit in 'int'.
2732
2733 * print.c (print_object): Use ptrdiff_t, not int, for index that can
2734 exceed INT_MAX.
2735
2736 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
2737 (Fvertical_motion): Don't wrap around LINES values that don't fit
2738 in 'int'. Instead, treat them as extreme values. This is good
2739 enough for windows, which can't have more than INT_MAX lines anyway.
2740
2741 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
2742
2743 * Require libxml/parser.h to avoid compilation warning.
2744
2745 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
2746
2747 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
2748 since this reportedly can destroy thread storage.
2749
2750 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
2751
2752 * syntax.c (find_defun_start): Update all cache variables if
2753 exiting early (Bug#9401).
2754
2755 2011-08-30 Eli Zaretskii <eliz@gnu.org>
2756
2757 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
2758
2759 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
2760 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
2761 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
2762
2763 * term.c (tty_append_glyph): New function.
2764 (produce_stretch_glyph): Static function and its prototype deleted.
2765
2766 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
2767 Add prototypes.
2768
2769 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
2770
2771 * image.c (parse_image_spec): Check for nonnegative, not for positive,
2772 when checking :margin (Bug#9390).
2773 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
2774 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
2775 so that the name doesn't mislead. All uses changed.
2776
2777 2011-08-28 Johan Bockgård <bojohan@gnu.org>
2778
2779 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
2780 set_tty_hooks.
2781
2782 2011-08-27 Eli Zaretskii <eliz@gnu.org>
2783
2784 * xdisp.c (move_it_to): Don't bail out early when reaching
2785 position beyond to_charpos, if we are scanning backwards.
2786 (move_it_vertically_backward): When DY == 0, make sure we get to
2787 the first character in the line after the newline.
2788
2789 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
2790
2791 * ccl.c: Improve and simplify overflow checking (Bug#9196).
2792 (ccl_driver): Do not generate an out-of-range pointer.
2793 (Fccl_execute_on_string): Remove unnecessary check for
2794 integer overflow, noted by Stefan Monnier in
2795 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
2796 Remove a FIXME that didn't need fixing.
2797 Simplify the newly-introduced buffer reallocation code.
2798
2799 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
2800
2801 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
2802
2803 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
2804
2805 Integer and memory overflow issues (Bug#9196).
2806
2807 * doc.c (get_doc_string): Rework so that
2808 get_doc_string_buffer_size is the actual buffer size, rather than
2809 being 1 less than the actual buffer size; this makes xpalloc more
2810 convenient.
2811
2812 * image.c (x_allocate_bitmap_record, cache_image):
2813 * xselect.c (Fx_register_dnd_atom):
2814 Simplify previous changes by using xpalloc.
2815
2816 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
2817 since either will do and ptrdiff_t is convenient with xpalloc.
2818
2819 * charset.c (charset_table_size)
2820 (struct charset_sort_data.priority): Now ptrdiff_t.
2821 (charset_compare): Don't overflow if priorities differ greatly.
2822 (Fsort_charsets): Don't assume list length fits in int.
2823 Check for size-calculation overflow when allocating sort data.
2824 (syms_of_charset): Allocate an initial charset table that is
2825 just under 64 KiB, to avoid problems with glibc malloc and mmap.
2826
2827 * cmds.c (internal_self_insert): Check for size-calculation overflow.
2828
2829 * composite.h (struct composition.glyph_len): Now int, not unsigned.
2830 The actual value is always <= INT_MAX, and leaving it unsigned made
2831 overflow checking harder.
2832
2833 * dispextern.h (struct glyph_matrix.rows_allocated)
2834 (struct face_cache.size): Now ptrdiff_t, for convenience in use
2835 with xpalloc. The values are still always <= INT_MAX.
2836
2837 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
2838
2839 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
2840 (SAFE_NALLOCA): New macro.
2841
2842 * region-cache.c (struct boundary.pos, find_cache_boundary)
2843 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
2844 (set_cache_region, invalidate_region_cache)
2845 (revalidate_region_cache, know_region_cache, region_cache_forward)
2846 (region_cache_backward, pp_cache):
2847 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
2848 so that ptrdiff_t * can be passed to xpalloc.
2849 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
2850 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
2851 (pp_cache): Don't assume cache_len fits in int.
2852 * region-cache.h: Adjust extern decls to match.
2853
2854 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
2855 EMACS_INT, since either will do, for xpalloc.
2856
2857 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
2858 (xnmalloc, xnrealloc, xpalloc): New functions.
2859
2860 * bidi.c (bidi_shelve_header_size): New constant.
2861 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
2862 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
2863
2864 * bidi.c (bidi_cache_shrink):
2865 * buffer.c (overlays_at, overlays_in, record_overlay_string)
2866 (overlay_strings):
2867 Don't update size of array until after memory allocation succeeds,
2868 because xmalloc/xrealloc may not return.
2869 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
2870 now that we have proper integer overflow checking.
2871 (record_overlay_string, overlay_strings): Catch overflows when
2872 calculating size of overlay_str_buf.
2873
2874 * callproc.c (Fcall_process): Check for size overflow when
2875 calculating size of args2.
2876 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
2877 Normally we prefer signed values, but sticking with ptrdiff_t would
2878 require adding more-complicated checks.
2879
2880 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
2881 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
2882 Redo buffer-overflow calculations to avoid integer overflow.
2883 Add a FIXME comment where memory seems to be over-allocated.
2884
2885 * character.c (Fstring): Check for size-calculation overflow.
2886
2887 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
2888 unnecessary integer overflow. Check for size overflow.
2889 (encode_coding_object): Don't update size until xmalloc succeeds.
2890
2891 * composite.c (get_composition_id): Check for overflow in glyph
2892 length calculations.
2893
2894 Integer and memory overflow fixes for display code.
2895 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
2896 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
2897 (scrolling_window): Check for overflow in size calculations.
2898 (line_draw_cost, realloc_glyph_pool, add_row_entry):
2899 Don't assume glyph table len fits in int.
2900 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
2901 (row_table_size): Now ptrdiff_t, not int.
2902 (scrolling_window): Avoid overflow in size calculations.
2903 Don't update size until allocation succeeds.
2904 * fns.c (concat): Check for overflow in size calculations.
2905 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
2906 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
2907 (NEXT_ALMOST_PRIME_LIMIT): New constant.
2908
2909 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
2910 (get_doc_string): Check for size calculation overflow.
2911 Don't update size until allocation succeeds.
2912 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
2913 EMACS_INT, where ptrdiff_t will do.
2914 (Fsubstitute_command_keys): Check for string overflow.
2915
2916 * editfns.c (set_time_zone_rule): Don't assume environment length
2917 fits in int.
2918 (message_length): Now ptrdiff_t, not int.
2919 (Fmessage_box): Don't update size until allocation succeeds.
2920 Don't assume message length fits in int.
2921 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
2922
2923 * emacs.c (main): Do not reallocate argv, since there is a null at
2924 the end that can be overwritten, and this way there's no need to
2925 worry about size-calculation overflow.
2926 (sort_args): Check for size-calculation overflow.
2927
2928 * eval.c (init_eval_once, grow_specpdl): Don't update size until
2929 alloc succeeds.
2930 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
2931
2932 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
2933 (x_set_scroll_bar_width, x_figure_window_size):
2934 Check for integer overflow.
2935 (x_set_alpha): Do not assume XINT fits in int.
2936
2937 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
2938 This is for the members text_lines, text_cols, total_lines, total_cols,
2939 where the system imposes an 'int' limit.
2940
2941 * fringe.c (Fdefine_fringe_bitmap):
2942 Don't update size until alloc works.
2943
2944 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
2945 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
2946
2947 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
2948 Check for size-calculation overflow.
2949 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
2950 do, as we prefer signed integers.
2951 (id_to_widget.max_size, id_to_widget.used)
2952 (xg_store_widget_in_map, xg_remove_widget_from_map)
2953 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
2954 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
2955 Use and return ptrdiff_t, not int.
2956 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
2957 * gtkutil.h: Change prototypes to match the above.
2958
2959 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
2960 are duplicate now that they've been promoted to lisp.h.
2961 (x_allocate_bitmap_record, x_alloc_image_color)
2962 (make_image_cache, cache_image, xpm_load):
2963 Don't update size until alloc is done.
2964 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
2965 (x_detect_edges):
2966 Check for size calculation overflow.
2967 (ct_colors_allocated_max): New constant.
2968 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
2969 overflow.
2970
2971 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
2972 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
2973 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
2974 Use ptrdiff_t, not int, to count maps.
2975 (read_char_minibuf_menu_prompt): Check for overflow in size
2976 calculations. Don't update size until allocation succeeds.
2977 Redo calculations to avoid overflow.
2978 * keyboard.h: Change prototypes to match the above.
2979
2980 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
2981 to count maps.
2982 (current_minor_maps): Check for size calculation overflow.
2983 * keymap.h: Change prototypes to match the above.
2984
2985 * lread.c (read1, init_obarray): Don't update size until alloc done.
2986
2987 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
2988 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
2989
2990 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
2991 Now ptrdiff_t, not int.
2992 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

3003 * search.c (Freplace_match): Check for size calculation overflow.
3004 (Fset_match_data): Don't assume list lengths fit in 'int'.
3005
3006 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
3007 for command line length. Do not attempt to address one before the
3008 beginning of an array, as that's not portable.
3009
3010 * term.c (max_frame_lines): Remove; unused.
3011 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
3012 not int.
3013 (encode_terminal_code, calculate_costs): Check for size
3014 calculation overflow.
3015 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph

3019
3020 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
3021 subtracting pointers.
3022 (gobble_line): Check for overflow more carefully. Don't update size
3023 until alloc done.
3024
3025 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
3026 Don't update size until alloc done.

3037 (Finternal_make_lisp_face, cache_face):
3038 Check for size calculation overflow.
3039 (cache_face): Treat size calculation overflows as if they were
3040 memory exhaustion (the usual treatment), rather than aborting.
3041
3042 * xfns.c (x_encode_text, x_set_name_internal)
3043 (Fx_change_window_property): Use ptrdiff_t, not int, to count
3044 sizes, since they can exceed INT_MAX in size. Check for size
3045 calculation overflow.
3046
3047 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
3048 (xg_select): Check for size calculation overflow.
3049 Don't update size until alloc done.
3050
3051 * xrdb.c (get_environ_db): Don't assume path length fits in int,
3052 as sprintf is limited to int lengths.
3053
3054 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
3055 (X_LONG_MIN): New macros.
3056 Use them to make the following changes clearer.
3057 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
3058 This change doesn't affect the value now, but it may help remind
3059 future maintainers not to raise the value too much later.
3060 (SELECTION_QUANTUM): Remove, replacing with ...
3061 (selection_quantum): ... new function, which avoids overflow.
3062 All uses changed.
3063 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
3064 assumption that selection length fits in 'int'.
3065 (x_reply_selection_request, x_handle_selection_request)
3066 (x_get_window_property, receive_incremental_selection)
3067 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
3068 (lisp_data_to_selection_data, clean_local_selection_data):

3070 (x_reply_selection_request, x_get_window_property)
3071 (receive_incremental_selection, x_property_data_to_lisp):
3072 Redo calculations to avoid overflow.
3073 (x_reply_selection_request): When sending hint, ceiling it at
3074 X_LONG_MAX rather than relying on wraparound overflow to send
3075 something.
3076 (x_get_window_property, receive_incremental_selection)
3077 (lisp_data_to_selection_data, x_property_data_to_lisp):
3078 Check for size-calculation overflow.
3079 (x_get_window_property, receive_incremental_selection)
3080 (lisp_data_to_selection_data, Fx_register_dnd_atom):
3081 Don't store size until memory allocation succeeds.
3082 (x_get_window_property): Plug memory leak on memory exhaustion.
3083 Don't double-block input; malloc is safe here. Don't assume 2**34
3084 - 4 fits in unsigned long. Add an xassert to check
3085 XGetWindowProperty overflow. Be more careful about overflow
3086 calculations, and distinguish size from memory overflow better.
3087 (receive_incremental_selection): When tracing, don't assume
3088 unsigned int is less than INT_MAX.
3089 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
3090 harmful) conversions of unsigned short to int.
3091 (lisp_data_to_selection_data): Don't assume that integers
3092 in the range -65535 through -1 fit in an X unsigned short.
3093 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
3094 result parameters unless successful. Rely on cons_to_unsigned
3095 to report problems with elements; the old code wasn't right anyway.
3096 (x_check_property_data): Check for int overflow; we cannot use
3097 a wider type due to X limits.
3098 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
3099
3100 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
3101

3103 (x_term_init): Check for size calculation overflow.
3104 (x_color_cells): Don't store size until memory allocation succeeds.
3105 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
3106 Don't assume alloca size is less than MAX_ALLOCA.
3107 (x_term_init): Don't assume length fits in int (sprintf is limited
3108 to int size).
3109
3110 Use ptrdiff_t for composition IDs.
3111 * character.c (lisp_string_width):
3112 * composite.c (composition_table_size, n_compositions)

3129 * image.c (xpm_get_color_table_h):
3130 * lisp.h (hash_lookup, hash_put):
3131 * minibuf.c (Ftest_completion):
3132 Use ptrdiff_t for hash table indexes, not int (which is too
3133 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
3134 32-bit --with-wide-int hosts).
3135
3136 * charset.c (Fdefine_charset_internal): Check for integer overflow.
3137 Add a FIXME comment about memory leaks.
3138 (syms_of_charset): Don't assume xmalloc returns.
3139
3140 Don't assume that stated character widths fit in int.
3141 * character.c (Fchar_width, c_string_width, lisp_string_width):
3142 * character.h (CHAR_WIDTH):
3143 * indent.c (MULTIBYTE_BYTES_WIDTH):
3144 Use sanitize_char_width to avoid undefined and/or bad behavior
3145 with outlandish widths.
3146 * character.h (sanitize_tab_width): Rename from sanitize_width,
3147 now that we have two such functions. All uses changed.
3148 (sanitize_char_width): New inline function.
3149

3164
3165 * xterm.c: Don't go over XClientMessageEvent limit.
3166 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
3167 (x_send_scroll_bar_event): Likewise. Check that the size does not
3168 exceed limits imposed by XClientMessageEvent, as well as the usual
3169 ptrdiff_t and size_t limits.
3170
3171 * keyboard.c: Overflow, signedness and related fixes.
3172 (make_lispy_movement): Use same integer type in forward decl
3173 that is used in the definition.
3174 (read_key_sequence, keyremap_step):
3175 Change bufsize argument back to int, undoing my 2011-03-30 change.
3176 We prefer signed types, and int is wide enough here.
3177 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
3178 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
3179 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
3180 length, not size_t. Use ptrdiff_t for index, not int.
3181 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
3182 possibility of integer overflow.
3183
3184 Overflow, signedness and related fixes for images.

3193 * nsmenu.m (update_frame_tool_bar):
3194 * xdisp.c (calc_pixel_width_or_height):
3195 * xfns.c (image_cache_refcount):
3196 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
3197 on typical 64-bit hosts.

3203 when the callers expect that.
3204 (image_ascent): Redo ascent calculation to avoid int overflow.
3205 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
3206 (lookup_image): Remove unnecessary tests.
3207 (xbm_image_p): Locals are now of int, not EMACS_INT,
3208 since parse_image_check makes sure they fit into int.
3209 (png_load, gif_load, svg_load_image):
3210 Prefer int to unsigned where either will do.
3211 (tiff_handler): New function, combining the cores of the
3212 old tiff_error_handler and tiff_warning_handler.
3213 This function is rewritten to use vsnprintf and thereby avoid
3214 stack buffer overflows. It uses only the features of vsnprintf
3215 that are common to both POSIX and native Microsoft.
3216 (tiff_error_handler, tiff_warning_handler): Use it.
3217 (tiff_load, gif_load, imagemagick_load_image):
3218 Don't assume :index value fits in 'int'.
3219 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
3220 (imagemagick_load_image): Check that crop parameters fit into
3221 the integer types that MagickCropImage accepts. Don't assume
3222 Vimagemagick_render_type has a nonnegative value. Don't assume
3223 size_t fits in 'long'.
3224 (gs_load): Use printmax_t to print the widest integers possible.
3225 Check for integer overflow when computing image height and width.

3233
3234 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
3235 the display spec is of the form `(space ...)'.
3236 (handle_display_spec): Return the value returned by
3237 handle_single_display_spec, not just 1 or zero.
3238 (handle_single_display_spec): If the display spec is of the form
3239 `(space ...)', and specifies display in the text area, return 2
3240 rather than 1.
3241 (try_cursor_movement): Check for the need to scroll more
3242 accurately, and prefer exact match for point under bidi.
3243 Don't advance `row' beyond the last row of the window.
3244
3245 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
3246 into disp_prop; all users changed.
3247

3261 buffers, return left-to-right.
3262 (set_cursor_from_row): Consider candidate row a win if its glyph
3263 represents a newline and point is on that newline. Fixes cursor
3264 positioning on the newline at EOL of R2L text within L2R
3265 paragraph, and vice versa.
3266 (try_cursor_movement): Check continued rows, in addition to
3267 continuation rows. Fixes unwarranted scroll when point enters a
3268 continued line of R2L text within an L2R paragraph, or vice versa.
3269 (cursor_row_p): Consider the case of point being equal to
3270 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
3271 from the end of a short line to the beginning of a continued line
3272 of R2L text within L2R paragraph.
3273 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
3274 composed characters.
3275

3295
3296 * xdisp.c (redisplay_window): When computing centering_position,
3297 account for the height of the header line. (Bug#8874)
3298
3299 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
3300 instead of CHAR_TO_BYTE. Fixes a crash when a completion
3301 candidate is selected by the mouse, and that candidate has a
3302 composed character under the mouse.
3303
3304 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
3305 coordinates reported by pos-visible-in-window-p for a composed
3306 character in column zero.

3312 2011-08-22 Eli Zaretskii <eliz@gnu.org>
3313
3314 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
3315 consider it a hit if to_charpos is anywhere in the range of the
3316 composed buffer positions.
3317
3318 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
3319
3320 * image.c (gif_load): Don't assume that each subimage has the same
3321 dimensions as the base image. Handle disposal method that is
3322 "undefined" by the gif spec (Bug#9335).
3323
3324 2011-08-20 Chong Yidong <cyd@stupidchicken.com>

3338 with a composed character.
3339
3340 2011-08-18 Eli Zaretskii <eliz@gnu.org>
3341
3342 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
3343 character bidirectional type, use STRONG_L instead. Fixes crashes
3344 in a buffer produced by `describe-categories'.
3345
3346 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
3347 members before the level stack, so they would be saved and
3348 restored when copying iterator state. Fixes incorrect reordering
3349 around TABs covered by display properties.
3350
3351 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

3418 * process.c (create_process): Call setup_process_coding_systems
3419 after the pid of the process is set to -1 (Bug#8162).
3420
3421 2011-08-14 Eli Zaretskii <eliz@gnu.org>
3422
3423 * xdisp.c (move_it_in_display_line_to): Don't invoke
3424 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
3425 ppos_it. Fixes vertical cursor motion when line beginning is
3426 covered by an image. (Bug#9296)
3427
3428 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
3429
3430 * nsterm.h (ns_run_ascript): Declare.
3431 (NSAPP_DATA2_RUNASSCRIPT): Define.
3432
3433 * nsfns.m (as_script, as_result, as_status): New static variables.
3434 (ns_run_ascript): New function.
3435 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
3436 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
3437 the event loop. Get status from as_status (Bug#7276).
3438
3439 * nsterm.m (sendEvent): If event is NSApplicationDefined and
3440 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
3441 the event loop (Bug#7276).
3442
3443 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
3444
3445 * gnutls.c (QCgnutls_bootprop_priority)
3446 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
3447 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
3448 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
3449 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
3450 (QCgnutls_bootprop_verify_hostname_error)
3451 (QCgnutls_bootprop_callbacks_verify): Rename from
3452 Qgnutls_bootprop_..., all uses changed.
3453
3454 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
3455 uses changed.
3456
3457 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
3458
3459 * xfaces.c (Qframe_set_background_mode): Now static.
3460 * dispextern.h (Qframe_set_background_mode): Remove decl.
3461
3462 * process.c (Fnetwork_interface_info): Declare local only if needed.
3463
3464 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
3465
3466 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
3467 (Fnetwork_interface_list): Allocate in increments of bytes instead
3468 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
3469 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
3470 sockaddr.
3471 (struct ifflag_def): notrailers is smart on OSX.
3472 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
3473 Get hardware address with getifaddrs if available.
3474
3475 2011-08-12 Eli Zaretskii <eliz@gnu.org>
3476
3477 * xdisp.c (iterate_out_of_display_property): xassert that
3478 IT->position is set to within IT->object's boundaries. Break from
3479 the loop as soon as EOB is reached; avoids infloops in redisplay
3480 when IT->position is set up wrongly due to some bug.
3481 Set IT->current to match the bidi iterator unconditionally.
3482 (push_display_prop): Allow GET_FROM_STRING as IT->method on
3483 entry. Force push_it to save on the stack the current
3484 buffer/string position, to be restored by pop_it. Fix flags in
3485 the iterator structure wrt the object coming from a display
3486 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
3487 properties. (Bug#9284)
3488
3489 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
3490
3491 * fontset.c (fontset_get_font_group): Add proper type checks.
3492 (Bug#9172)
3493
3494 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3495
3496 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
3497 and LC_VERSION_MIN_MACOSX.
3498 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
3499 (dump_it) [LC_FUNCTION_STARTS]: Use it.
3500
3501 2011-08-08 Eli Zaretskii <eliz@gnu.org>
3502
3503 * xdisp.c (forward_to_next_line_start): Allow to use the
3504 no-display-properties-and-no-overlays under bidi display.
3505 Set disp_pos in the bidi iterator to avoid searches for display
3506 properties and overlays.
3507
3508 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
3509
3510 * editfns.c (Fset_time_zone_rule): Document relationship with the
3511 setenv function.
3512
3513 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
3514 the font entity extracted from the cache (Bug#8109).
3515
3516 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
3517
3518 * composite.c (autocmp_chars): Don't reset point. That is done by
3519 restore_point_unwind (Bug#5984).
3520
3521 2011-08-07 Juri Linkov <juri@jurta.org>
3522
3523 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
3524 to show the arg `TIME' instead of `TIMEVAL'.
3525
3526 2011-08-06 Eli Zaretskii <eliz@gnu.org>
3527
3528 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
3529 display property strides EOL and includes a newline, as in
3530 longlines-mode. (Bug#9254)
3531 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
3532 word-wrap under bidirectional display. (Bug#9224)
3533
3534 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
3535 is non-zero, even if the data buffer is NULL. Fixes a crash in
3536 vertical-motion with longlines-mode. (Bug#9254)
3537
3538 2011-08-05 Eli Zaretskii <eliz@gnu.org>
3539
3540 * bidi.c <bidi_cache_total_alloc>: Now static.
3541 (bidi_initialize): Initialize bidi_cache_total_alloc.
3542
3543 * xdisp.c (display_line): Release buffer allocated for shelved bidi
3544 cache. (Bug#9221)
3545
3546 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
3547 amount allocated this far in `bidi_cache_total_alloc'.
3548 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
3549 non-zero, only free the data buffer without restoring the cache
3550 contents. All callers changed.
3551
3552 * dispextern.h (bidi_unshelve_cache): Update prototype.
3553
3554 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
3555 (move_it_in_display_line, move_it_to)
3556 (move_it_vertically_backward, move_it_by_lines): Replace the call
3557 to xfree to an equivalent call to bidi_unshelve_cache.
3558 (move_it_in_display_line_to): Fix logic of returning
3559 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
3560
3561 2011-08-05 Eli Zaretskii <eliz@gnu.org>
3562
3563 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
3564 came from a string character with a `cursor' property. (Bug#9229)
3565
3566 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
3567
3568 * Makefile.in (LIB_PTHREAD): New variable.
3569 (LIBES): Add LIB_PTHREAD (Bug#9216).
3570
3571 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
3572 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
3573
3574 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
3575
3576 * regex.c (re_iswctype): Remove some redundant boolean conversions.
3577
3578 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
3579
3580 * xterm.c (x_find_topmost_parent): New function.
3581 (x_set_frame_alpha): Find topmost parent window with
3582 x_find_topmost_parent and set the property there also (bug#9181).
3583 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
3584
3585 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
3586
3587 * callproc.c (Fcall_process): Avoid vfork clobbering
3588 the local vars buffer, coding_systems, current_dir.
3589
3590 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
3591
3592 * keymap.c (Fmake_composed_keymap): Move to subr.el.
3593
3594 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
3595
3596 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
3597 so that it is not optimized away.
3598
3599 * xdisp.c (compute_display_string_pos): Remove unused local.
3600
3601 2011-08-02 Eli Zaretskii <eliz@gnu.org>
3602
3603 Fix slow cursor motion and scrolling in large buffers with
3604 selective display, like Org Mode buffers. (Bug#9218)
3605
3606 * dispextern.h (struct bidi_it): New member disp_prop_p.
3607
3608 * xdisp.c: Remove one-slot cache of display string positions.
3609 (compute_display_string_pos): Accept an additional argument
3610 DISP_PROP_P; callers changed. Scan at most 5K characters forward
3611 for a display string or property. If found, set DISP_PROP_P
3612 non-zero.
3613
3614 * bidi.c (bidi_fetch_char): Accept an additional argument
3615 DISP_PROP_P, and pass it to compute_display_string_pos.
3616 Only handle text covered by a display string if DISP_PROP_P is returned
3617 non-zero. All callers of bidi_fetch_char changed.
3618
3619 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
3620
3621 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
3622
3623 2010-12-03 Don March <don@ohspite.net>
3624
3625 * keymap.c (Fdefine_key): Fix non-prefix key error message when
3626 last character M-[char] is translated to ESC [char] (bug#7541).
3627
3628 2011-08-02 Kenichi Handa <handa@m17n.org>
3629
3630 * lisp.h (uniprop_table): Extern it.
3631
3632 * chartab.c (uniprop_table): Make it non-static.
3633
3634 2011-08-01 Eli Zaretskii <eliz@gnu.org>
3635
3636 * xdisp.c (forward_to_next_line_start): Accept additional argument
3637 BIDI_IT_PREV, and store into it the state of the bidi iterator had
3638 on the newline.
3639 (reseat_at_next_visible_line_start): Use the bidi iterator state
3640 returned by forward_to_next_line_start to restore the state of
3641 it->bidi_it after backing up to previous newline. (Bug#9212)
3642
3643 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
3644
3645 * regex.c (re_comp): Protoize.
3646 (re_exec): Fix return type.
3647 (regexec): Fix type of `ret'. (Bug#9203)
3648
3649 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3650
3651 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
3652 This is needed if max-image-size is a floating-point number.
3653
3654 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
3655
3656 * print.c (print_object): Print empty symbol as ##.
3657
3658 * lread.c (read1): Read ## as empty symbol.
3659
3660 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
3661
3662 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
3663 setting frame foreground color (Bug#9175).
3664 (x_set_background_color): Likewise.
3665
3666 * nsmenu.m (-setText): Size tooltip dimensions precisely to
3667 contents (Bug#9176).
3668 (EmacsTooltip -init): Remove bezels and add shadows to
3669 tooltip windows.
3670
3671 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
3672 or scroll bar (Bug#8470).
3673
3674 * nsfont.m (nsfont_open): Remove assignment to voffset and
3675 unnecessary vars hshink, expand, hd, full_height, min_height.
3676 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
3677
3678 * nsterm.h (nsfont_info): Remove voffset field.
3679
3680 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
3681
3682 Implement strike-through and overline on NextStep (Bug#8863).
3683
3684 * nsfont.m (nsfont_open): Use underline position provided by font,
3685 instead of hard-coded value of 2.
3686 (nsfont_draw): Call ns_draw_text_decoration instead.
3687
3688 * nsterm.h: Add declaration for ns_draw_text_decoration.
3689
3690 * nsterm.m (ns_draw_text_decoration): New function for drawing
3691 underline, overline, and strike-through.
3692 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
3693 ns_draw_text_decoration. Change treatment of cursor drawing to
3694 accommodate underlining, etc.
3695
3696 2011-07-28 Eli Zaretskii <eliz@gnu.org>
3697
3698 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
3699 default.
3700
3701 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3702
3703 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
3704 Without this fix, if a signal arrives just after memory fills up,
3705 'malloc' might be invoked reentrantly.
3706
3707 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
3708 In other words, assume that every image size is allowed, on non-X
3709 hosts. This assumption is probably wrong, but it lets Emacs compile.
3710
3711 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
3712
3713 * regex.c (re_iswctype): Convert return values to boolean.
3714
3715 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
3716
3717 * xdisp.c (compute_display_string_pos): Don't use cached display
3718 string position if the buffer had its restriction changed.
3719 (Bug#9184)
3720
3721 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3722
3723 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3724
3725 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3726
3727 Integer signedness and overflow and related fixes. (Bug#9079)
3728
3729 * bidi.c: Integer size and overflow fixes.
3730 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
3731 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
3732 (bidi_cache_find_level_change, bidi_cache_ensure_space)
3733 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
3734 (bidi_find_other_level_edge):
3735 Use ptrdiff_t instead of EMACS_INT where either will do.
3736 This works better on 32-bit hosts configured --with-wide-int.
3737 (bidi_cache_ensure_space): Check for size-calculation overflow.
3738 Use % rather than repeated addition, for better worst-case speed.
3739 Don't set bidi_cache_size until after xrealloc returns, because it
3740 might not return.
3741 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
3742 (bidi_cache_ensure_space): Also check that the bidi cache size
3743 does not exceed that of the largest Lisp string or buffer. See Eli
3744 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
3745
3746 * alloc.c (__malloc_size_t): Remove.
3747 All uses replaced by size_t. See Andreas Schwab's note
3748 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
3749
3750 * image.c: Improve checking for integer overflow.
3751 (check_image_size): Assume that f is nonnull, since
3752 it is always nonnull in practice. This is one less thing to
3753 worry about when checking for integer overflow later.
3754 (x_check_image_size): New function, which checks for integer
3755 overflow issues inside X.
3756 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
3757 This removes the need for a memory_full check.
3758 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
3759 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
3760 (xbm_read_bitmap_data): Change locals back to 'int', since
3761 their values must fit in 'int'.
3762 (xpm_load_image, png_load, tiff_load):
3763 Invoke x_create_x_image_and_pixmap earlier,
3764 to avoid much needless work if the image is too large.
3765 (tiff_load): Treat overly large images as if
3766 x_create_x_image_and_pixmap failed, not as malloc failures.
3767 (gs_load): Use x_check_image_size.
3768
3769 * gtkutil.c: Omit integer casts.
3770 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
3771 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
3772
3773 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
3774
3775 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
3776 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
3777 would wrongly return t on a 64-bit host.
3778
3779 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
3780 The plain *_OVERFLOW macros run afoul of GCC bug 49705
3781 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
3782 and therefore cause GCC to emit a bogus diagnostic in some cases.
3783
3784 * image.c: Integer signedness and overflow and related fixes.
3785 This is not an exhaustive set of fixes, but it's time to
3786 record what I've got.
3787 (lookup_pixel_color, check_image_size): Remove redundant decls.
3788 (check_image_size): Don't assume that arbitrary EMACS_INT values
3789 fit in 'int', or that arbitrary 'double' values fit in 'int'.
3790 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
3791 (tiff_load, imagemagick_load_image):
3792 Check for overflow in size calculations.
3793 (x_create_x_image_and_pixmap): Remove unnecessary test for
3794 xmalloc returning NULL; that can't happen.
3795 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
3796 (xpm_color_bucket): Use better integer hashing function.
3797 (xpm_cache_color): Don't possibly over-allocate memory.
3798 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
3799 (gif_memory_source):
3800 Use ptrdiff_t, not int or size_t, to record sizes.
3801 (png_load): Don't assume values greater than 2**31 fit in 'int'.
3802 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
3803 either works, as we prefer signed integers.
3804 (tiff_read_from_memory, tiff_write_from_memory):
3805 Return tsize_t, not size_t, since that's what the TIFF API wants.
3806 (tiff_read_from_memory): Don't fail simply because the read would
3807 go past EOF; instead, return a short read.
3808 (tiff_load): Omit no-longer-needed casts.
3809 (Fimagemagick_types): Don't assume size fits into 'int'.
3810
3811 Improve hashing quality when configured --with-wide-int.
3812 * fns.c (hash_string): New function, taken from sxhash_string.
3813 Do not discard information about ASCII character case; this
3814 discarding is no longer needed.
3815 (sxhash-string): Use it. Change sig to match it. Caller changed.
3816 * lisp.h: Declare it.
3817 * lread.c (hash_string): Remove, since we now use fns.c's version.
3818 The fns.c version returns a wider integer if --with-wide-int is
3819 specified, so this should help the quality of the hashing a bit.
3820
3821 * emacs.c: Integer overflow minor fix.
3822 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
3823 Define only if GNU_LINUX.
3824 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
3825
3826 * dispnew.c: Integer signedness and overflow fixes.
3827 Remove unnecessary forward decls, that were a maintenance hassle.
3828 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
3829 All uses changed.
3830 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
3831 (scrolling_window): Use ptrdiff_t, not int, for byte count.
3832 (prepare_desired_row, line_draw_cost):
3833 Use int, not unsigned, where either works.
3834 (save_current_matrix, restore_current_matrix):
3835 Use ptrdiff_t, not size_t, where either works.
3836 (init_display): Check for overflow more accurately, and without
3837 relying on undefined behavior.
3838
3839 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
3840 Remove, replacing with the new symbols in lisp.h. All uses changed.
3841 * fileio.c (make_temp_name):
3842 * filelock.c (lock_file_1, lock_file):
3843 * xdisp.c (message_dolog):
3844 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
3845 Use pMd etc. instead.
3846 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
3847 replacing the pWIDE etc. symbols removed from editfns.c.
3848
3849 * keyboard.h (num_input_events): Now uintmax_t.
3850 This is (very slightly) less likely to mess up due to wraparound.
3851 All uses changed.
3852
3853 * buffer.c: Integer signedness fixes.
3854 (alloc_buffer_text, enlarge_buffer_text):
3855 Use ptrdiff_t rather than size_t when either will do, as we prefer
3856 signed integers.
3857
3858 * alloc.c: Integer signedness and overflow fixes.
3859 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
3860 (__malloc_size_t): Default to size_t, not to int.
3861 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
3862 (Fgarbage_collect, mark_object_loop_halt, mark_object):
3863 Prefer ptrdiff_t to size_t when either would do, as we prefer
3864 signed integers.
3865 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
3866 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
3867 Now const. Initialize with values that are in range even if char
3868 is signed.
3869 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
3870 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
3871 These functions do the right thing with sizes > 2**32.
3872 (check_depth): Now ptrdiff_t, not int.
3873 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
3874 Adjust to new way of storing sizes. Check for size overflow bugs
3875 in rest of code.
3876 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
3877 slightly wrong anyway, as it missed one instance of
3878 XMALLOC_OVERRUN_CHECK_OVERHEAD.
3879 (refill_memory_reserve): Omit needless cast to size_t.
3880 (mark_object_loop_halt): Mark as externally visible.
3881
3882 * xselect.c: Integer signedness and overflow fixes.
3883 (Fx_register_dnd_atom, x_handle_dnd_message):
3884 Use ptrdiff_t, not size_t, since we prefer signed.
3885 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
3886 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
3887 x_dnd_atoms_size and x_dnd_atoms_length.
3888
3889 * doprnt.c: Prefer signed to unsigned when either works.
3890 * eval.c (verror):
3891 * doprnt.c (doprnt):
3892 * lisp.h (doprnt):
3893 * xdisp.c (vmessage):
3894 Use ptrdiff_t, not size_t, when using or implementing doprnt,
3895 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
3896 prefer signed arithmetic to avoid comparison confusion.
3897 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
3898 but is a bit tricky.
3899
3900 Assume freestanding C89 headers, string.h, stdlib.h.
3901 * data.c, doprnt.c, floatfns.c, print.c:
3902 Include float.h unconditionally.
3903 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
3904 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
3905 * regex.c: Likewise for stddef.h, string.h.
3906 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
3907 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
3908 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
3909 (STDC_HEADERS): Remove obsolete defines.
3910 * sysdep.c: Include limits.h unconditionally.
3911
3912 Assume support for memcmp, memcpy, memmove, memset.
3913 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
3914 * regex.c (memcmp, memcpy):
3915 Remove; we assume C89 now.
3916
3917 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
3918 (__malloc_safe_bcopy): Remove; no longer needed.
3919
3920 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
3921 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
3922 well either way, and we prefer signed to unsigned.
3923
3924 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
3925
3926 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
3927 closes the connection while we're reading (bug#9182).
3928
3929 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
3930
3931 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
3932 are specified (Bug#9168).
3933
3934 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
3935
3936 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
3937 Found by GCC static checking and --with-wide-int on a 32-bit host.
3938
3939 2011-07-25 Eli Zaretskii <eliz@gnu.org>
3940
3941 * xdisp.c (compute_display_string_pos): Fix logic of caching
3942 previous display string position. Initialize cached_prev_pos to
3943 -1. Fixes slow-down at the beginning of a buffer.
3944
3945 2011-07-24 Eli Zaretskii <eliz@gnu.org>
3946
3947 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
3948 for attrs[LFACE_FONTSET_INDEX].
3949
3950 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
3951
3952 * xml.c (parse_region): Remove unused local
3953 that was recently introduced.
3954
3955 2011-07-23 Eli Zaretskii <eliz@gnu.org>
3956
3957 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
3958 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
3959
3960 * xdisp.c (move_it_in_display_line_to): Record the best matching
3961 position for TO_CHARPOS while scanning the line, and restore it on
3962 exit if none of the characters scanned was an exact match.
3963 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
3964 when exact match is impossible due to invisible text, and the
3965 lines are truncated.
3966
3967 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
3968
3969 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
3970 for OSX >= 10.7.
3971
3972 2011-07-22 Eli Zaretskii <eliz@gnu.org>
3973
3974 Fix a significant slow-down of cursor motion with C-n, C-p,
3975 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
3976 auto-repeat under bidi redisplay in fontified buffers.
3977 * xdisp.c (compute_stop_pos_backwards): New function.
3978 (next_element_from_buffer): Call compute_stop_pos_backwards to
3979 find a suitable prev_stop when we find ourselves before
3980 base_level_stop.
3981 (reseat): Don't look for prev_stop, as that could mean a very long
3982 run.
3983 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
3984 <cached_disp_overlay_modiff>: Cache for last found display string
3985 position.
3986 (compute_display_string_pos): Return the cached position if asked
3987 about the same buffer in the same area of character positions, and
3988 the buffer wasn't changed since the time the display string
3989 position was cached.
3990
3991 2011-07-22 Eli Zaretskii <eliz@gnu.org>
3992
3993 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
3994 is an integer, which is important for empty lines. (Bug#9149)
3995
3996 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
3997
3998 * frame.c (Fmodify_frame_parameters): In tty case, update the
3999 default face if necessary (Bug#4238).
4000
4001 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
4002
4003 * editfns.c (Fstring_to_char): No need to explain what a character
4004 is in the docstring (Bug#6576).
4005
4006 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
4007
4008 * xml.c (parse_region): Make sure we always return a tree.
4009
4010 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
4011
4012 * xml.c (parse_region): If a document contains only comments,
4013 return that, too.
4014
4015 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
4016
4017 * xml.c (make_dom): Return comments, too.
4018
4019 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
4020
4021 Port to OpenBSD.
4022 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
4023 and the surrounding thread.
4024 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
4025 rather than fgets, and retry after EINTR. Otherwise, 'emacs
4026 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
4027 timer goes off.
4028 * s/openbsd.h (BROKEN_SIGIO): Define.
4029 * unexelf.c (unexec) [__OpenBSD__]:
4030 Don't update the .mdebug section of the Alpha COFF symbol table.
4031
4032 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
4033
4034 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
4035 (bug#8460).
4036
4037 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
4038
4039 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
4040 This fixes some race conditions on the permissions of any newly
4041 created file.
4042
4043 * alloc.c (valid_pointer_p): Use pipe, not open.
4044 This fixes some permissions issues when debugging.
4045
4046 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
4047 If fchown fails to set both uid and gid, try to set just gid,
4048 as that is sometimes allowed. Adjust the file's mode to eliminate
4049 setuid or setgid bits that are inappropriate if fchown fails.
4050
4051 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
4052
4053 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
4054 to compare Lisp_Objects.
4055 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
4056 global_gnutls_log_level, don't mistake it for a Lisp_Object.
4057 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
4058
4059 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
4060
4061 * lread.c (read_integer): Unread even EOF character.
4062 (read1): Likewise. Properly record start position of symbol.
4063
4064 * lread.c (read1): Read `#:' as empty uninterned symbol if no
4065 symbol character follows.
4066
4067 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
4068
4069 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
4070 This works around a problem with the previous change to Fcopy_file.
4071 Recent glibc declares fchown with __attribute__((warn_unused_result)),
4072 and without this change, GCC might complain about discarding
4073 fchown's return value.
4074
4075 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
4076
4077 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
4078
4079 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
4080
4081 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
4082
4083 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
4084
4085 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
4086 it's used from the C level.
4087
4088 * process.c: Use the same condition for POLL_FOR_INPUT in both
4089 keyboard.c and process.c (bug#1858).
4090
4091 2011-07-09 Lawrence Mitchell <wence@gmx.li>
4092
4093 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
4094 (Fgnutls_boot): Use it.
4095
4096 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
4097
4098 * doc.c (Fsubstitute_command_keys): Revert last change.
4099
4100 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
4101
4102 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
4103 quotes the next character, and doesn't affect other longer
4104 sequences (bug#8935).
4105
4106 * lread.c (syms_of_lread): Clarify that is isn't only
4107 `eval-buffer' and `eval-defun' that's affected by
4108 `lexical-binding' (bug#8460).
4109
4110 2011-07-15 Eli Zaretskii <eliz@gnu.org>
4111
4112 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
4113 bidi redisplay when a line includes both an image and is truncated.
4114
4115 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
4116
4117 Fix minor problems found by static checking.
4118 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
4119 (elsz): Now a signed constant, not a size_t var. We prefer signed
4120 types to unsigned, to avoid integer comparison confusion. Without
4121 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
4122 "cannot optimize loop, the loop counter may overflow", a symptom
4123 of the confusion.
4124 * indent.c (Fvertical_motion): Mark locals as initialized.
4125 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
4126
4127 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
4128
4129 * search.c (Fre_search_backward): Mention `case-fold-search' in
4130 all the re_search_* functions (bug#8138).
4131
4132 * keyboard.c (Fopen_dribble_file): Document when the file is
4133 closed (bug#8056).
4134
4135 2011-07-14 Eli Zaretskii <eliz@gnu.org>
4136
4137 * bidi.c (bidi_dump_cached_states): Fix format of displaying
4138 bidi_cache_idx.
4139
4140 Support bidi reordering of display and overlay strings.
4141 * xdisp.c (compute_display_string_pos)
4142 (compute_display_string_end): Accept additional argument STRING.
4143 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
4144 (reseat_to_string): Initialize bidi_it->string.s and
4145 bidi_it->string.schars.
4146 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
4147 NULL (avoids a crash in bidi_paragraph_init).
4148 Initialize itb.string.lstring.
4149 (init_iterator): Call bidi_init_it only of a valid
4150 buffer position was specified. Initialize paragraph_embedding to
4151 L2R.
4152 (reseat_to_string): Initialize the bidi iterator.
4153 (display_string): If we need to ignore text properties of
4154 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
4155 original value of -1 will not work with bidi.)
4156 (compute_display_string_pos): First arg is now struct
4157 `text_pos *'; all callers changed. Support display properties on
4158 Lisp strings.
4159 (compute_display_string_end): Support display properties on Lisp
4160 strings.
4161 (init_iterator, reseat_1, reseat_to_string): Initialize the
4162 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
4163 when iterating on a string not from display properties).
4164 (compute_display_string_pos, compute_display_string_end):
4165 Fix calculation of the object to scan. Fixes an error when using
4166 arrow keys.
4167 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
4168 base_level_stop; instead, set base_level_stop to BEGV.
4169 Fixes crashes in vertical-motion.
4170 (next_element_from_buffer): Improve commentary for when
4171 the iterator is before prev_stop.
4172 (init_iterator): Initialize bidi_p from the default value of
4173 bidi-display-reordering, not from buffer-local value. Use the
4174 buffer-local value only if initializing for buffer iteration.
4175 (handle_invisible_prop): Support invisible properties on strings
4176 that are being bidi-reordered.
4177 (set_iterator_to_next): Support bidi reordering of C strings and
4178 Lisp strings.
4179 (next_element_from_string): Support bidi reordering of Lisp
4180 strings.
4181 (handle_stop_backwards): Support Lisp strings as well.
4182 (display_string): Support display of R2L glyph rows.
4183 Use IT_STRING_CHARPOS when displaying from a Lisp string.
4184 (init_iterator): Don't initialize it->bidi_p for strings
4185 here.
4186 (reseat_to_string): Initialize it->bidi_p for strings here.
4187 (next_element_from_string, next_element_from_c_string)
4188 (next_element_from_buffer): Add xassert's for correspondence
4189 between IT's object being iterated and it->bidi_it.string
4190 structure.
4191 (face_before_or_after_it_pos): Support bidi iteration.
4192 (next_element_from_c_string): Handle the case of the first string
4193 character that is not the first one in the visual order.
4194 (get_visually_first_element): New function, refactored from common
4195 parts of next_element_from_buffer, next_element_from_string, and
4196 next_element_from_c_string.
4197 (tool_bar_lines_needed, redisplay_tool_bar)
4198 (display_menu_bar): Force left-to-right direction. Add a FIXME
4199 comment for making that be controlled by a user option.
4200 (push_it, pop_it): Save and restore the state of the
4201 bidi iterator. Save and restore the bidi_p flag.
4202 (pop_it): Iterate out of display property for string iteration as
4203 well.
4204 (iterate_out_of_display_property): Support iteration over strings.
4205 (handle_single_display_spec): Set up it->bidi_it for iteration
4206 over a display string, and call bidi_init_it.
4207 (handle_single_display_spec, next_overlay_string)
4208 (get_overlay_strings_1, push_display_prop): Set up the bidi
4209 iterator for displaying display or overlay strings.
4210 (forward_to_next_line_start): Don't use the shortcut if
4211 bidi-iterating.
4212 (back_to_previous_visible_line_start): If handle_display_prop
4213 pushed the iterator stack, restore the internal state of the bidi
4214 iterator by calling bidi_pop_it same number of times.
4215 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
4216 and we are bidi-iterating, don't decrement the iterator position;
4217 instead, set the first_elt flag in the bidi iterator, to produce
4218 the same effect.
4219 (reseat_1): Remove redundant setting of string_from_display_prop_p.
4220 (push_display_prop): xassert that we are iterating a buffer.
4221 (push_it, pop_it): Save and restore paragraph_embedding member.
4222 (handle_single_display_spec, next_overlay_string)
4223 (get_overlay_strings_1, reseat_1, reseat_to_string)
4224 (push_display_prop): Set up the `unibyte' member of bidi_it.string
4225 correctly. Don't assume unibyte strings are not bidi-reordered.
4226 (compute_display_string_pos)
4227 (compute_display_string_end): Fix handling the case of C string.
4228 (push_it, pop_it): Save and restore from_disp_prop_p.
4229 (handle_single_display_spec, push_display_prop): Set the
4230 from_disp_prop_p flag.
4231 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
4232 (pop_it): Call iterate_out_of_display_property only if we are
4233 popping after iteration over a string that came from a display
4234 property. Fix a typo in popping stretch info. Add an assertion
4235 for verifying that the iterator position is in sync with the bidi
4236 iterator.
4237 (handle_single_display_spec, get_overlay_strings_1)
4238 (push_display_prop): Fix initialization of paragraph direction for
4239 string when that of the parent object is not yet determined.

4652 if Emacs is configured with --with-wide-int.
4653 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
4654 New macros, used in the buffer.c change.

4689
4690 Random fixes. E.g., (random) never returned negative values.
4691 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
4692 subseconds part to the entropy, as that's a bit more random.
4693 Prefer signed to unsigned, since the signedness doesn't matter and
4694 in general we prefer signed. When given a limit, use a
4695 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
4696 latter isn't right if USE_2_TAGS_FOR_INTS.
4697 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
4698 not 0..VALMASK. Don't discard "excess" bits that random () returns.

4707
4708 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
4709
4710 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
4711 This is more efficient than Ffile_directory_p and avoids a minor race.
4712
4713 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
4714
4715 * buffer.c (Foverlay_put): Say what the return value is
4716 (bug#7835).
4717

4736 (syms_of_gnutls): Remove duplicate DEFSYM for
4737 Qgnutls_bootprop_verify_hostname_error, an error for
4738 Qgnutls_bootprop_verify_error (which is no longer used).
4739
4740 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
4741 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
4742 Also (re)move comments that are misplaced or no longer relevant.
4743

4798 (Fcopy_keymap): Handle embedded parents.
4799 (Fcommand_remapping, define_as_prefix): Simplify.

4824 (emacs_settings_set_property, emacs_settings_class_init)
4825 (emacs_settings_init, gsettings_obj): Remove.

4842
4843 * eval.c (struct backtrace): Simplify and port the data structure.
4844 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
4845 signed bit field, as this assumption is not portable and it makes
4846 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
4847 "char debug_on_exit : 1" as this is not portable either; instead,
4848 use the portable "unsigned int debug_on_exit : 1". Remove unused
4849 member evalargs. Remove obsolete comments about cc bombing out.
4850
4851 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

4893 matches the window's clone number process the overlay even if
4894 the overlay's window property doesn't match the current window.
4895
4896 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.
4897 (Fwindow_hchild): Rename to Fwindow_left_child.

5070 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
5071 Mark as externally visible.
5072 * dispnew.c (check_window_matrix_pointers): Now static.
5073 * dispnew.c (window_to_frame_vpos):
5074 * xfns.c (unwind_create_frame):
5075 * xterm.c (x_check_font): Remove unused local.
5076 * scroll.c (CHECK_BOUNDS):
5077 * xfaces.c (cache_fache): Rename local to avoid shadowing.
5078 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
5079 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
5080 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
5081 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
5082 Now static.
5083 (debug_method_add): Use va_list and vsprintf rather than relying
5084 on undefined behavior with wrong number of arguments.
5085 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
5086 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
5087 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
5088 since we're not interested in debugging glyphs with old libraries.
5089 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
5090 GCC 4.6.0's static checking.
5091
5092 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
5093
5094 Integer overflow and signedness fixes (Bug#8873).
5095 A few related buffer overrun fixes, too.
5096
5097 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
5098
5099 * dispextern.h (struct face.stipple):
5100 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
5101 (x_bitmap_mask, x_allocate_bitmap_record)
5102 (x_create_bitmap_from_data, x_create_bitmap_from_file)
5103 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
5104 (x_create_bitmap_from_xpm_data):
5105 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
5106 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
5107 (.bitmaps_last):
5108 * xfaces.c (load_pixmap):
5109 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
5110 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
5111 (.bitmaps_last, struct x_output.icon_bitmap):
5112 Use ptrdiff_t, not int, for bitmap indexes.
5113 (x_allocate_bitmap_record): Check for size overflow.
5114 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
5115
5116 Use ptrdiff_t, not int, for overlay counts.
5117 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
5118 * editfns.c (overlays_around, get_pos_property):
5119 * textprop.c (get_char_property_and_overlay):
5120 * xdisp.c (next_overlay_change, note_mouse_highlight):
5121 * xfaces.c (face_at_buffer_position):
5122 * buffer.c (OVERLAY_COUNT_MAX): New macro.
5123 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
5124 (Fnext_overlay_change, Fprevious_overlay_change)
5125 (mouse_face_overlay_overlaps, Foverlays_in):
5126 Use ptrdiff_t, not int, for sizes.
5127 (overlays_at, overlays_in): Check for size-calculation overflow.
5128
5129 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
5130
5131 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
5132 (x_session_initialize): Do not assume string length fits in int.
5133
5134 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
5135 This is unlikely, but can occur if DPI is outlandish.
5136
5137 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
5138 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
5139
5140 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
5141 * xrdb.c (magic_file_p, search_magic_path):
5142 Omit last arg SUFFIX; it was always 0. All callers changed.
5143 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
5144
5145 * xfont.c (xfont_match): Avoid need for strlen.
5146
5147 * xfns.c: Don't assume strlen fits in int.
5148 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
5149
5150 * xdisp.c (message_log_check_duplicate): Return intmax_t,
5151 not unsigned long, as we prefer signed integers. All callers changed.
5152 Detect integer overflow in repeat count.
5153 (message_dolog): Don't assume print length fits in 39 bytes.
5154 (display_mode_element): Don't assume strlen fits in int.
5155
5156 * termcap.c: Don't assume sizes fit in int and never overflow.
5157 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
5158 (gobble_line): Check for size-calculation overflow.
5159
5160 * minibuf.c (Fread_buffer):
5161 * lread.c (intern, intern_c_string):
5162 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
5163 Don't assume string length fits in int.
5164
5165 * keyboard.c (parse_tool_bar_item):
5166 * gtkutil.c (style_changed_cb): Avoid need for strlen.
5167
5168 * font.c: Don't assume string length fits in int.
5169 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
5170 Use ptrdiff_t, not int.
5171 (font_intern_prop): Don't assume string length fits in int.
5172 Don't assume integer property fits in fixnum.
5173 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
5174
5175 * filelock.c: Fix some buffer overrun and integer overflow issues.
5176 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
5177 Reformulate so as not to need the command string.
5178 Invoke gzip -cd rather than gunzip, as it's more portable.
5179 (lock_info_type, lock_file_1, lock_file):
5180 Don't assume pid_t and time_t fit in unsigned long.
5181 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
5182 (current_lock_owner): Prefer signed type for sizes.
5183 Use memcpy, not strncpy, where memcpy is what is really wanted.
5184 Don't assume (via atoi) that time_t and pid_t fit in int.
5185 Check for time_t and/or pid_t out of range, e.g., via a network share.
5186 Don't alloca where an auto var works fine.
5187
5188 * fileio.c: Fix some integer overflow issues.
5189 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
5190 Don't assume string length fits in int.
5191 (directory_file_name): Don't assume string length fits in long.
5192 (make_temp_name): Don't assume pid fits in int, or that its print
5193 length is less than 20.
5194
5195 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
5196
5197 * coding.c (make_subsidiaries): Don't assume string length fits in int.
5198
5199 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
5200
5201 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
5202 We prefer signed integers, even for size calculations.
5203
5204 * emacs.c: Don't assume string length fits in 'int'.
5205 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
5206 (main): Don't invoke strlen when not needed.
5207
5208 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
5209 (XD_DEBUG_MESSAGE): Don't waste a byte.
5210
5211 * callproc.c (getenv_internal_1, getenv_internal)
5212 (Fgetenv_internal):
5213 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
5214
5215 * lread.c (invalid_syntax): Omit length argument.
5216 All uses changed. This doesn't fix a bug, but it simplifies the
5217 code away from its former Hollerith-constant appearance, and it's
5218 one less 'int' to worry about when looking at integer-overflow issues.
5219 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
5220
5221 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
5222 This didn't break anything, but it didn't help either.
5223 It's confusing to put a bogus integer in a place where the actual
5224 value does not matter.
5225 (LIST_END_P): Remove unused macro and its bogus comment.
5226 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
5227
5228 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
5229 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
5230 implementation.
5231 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
5232 We prefer signed types, and the value cannot exceed the EMACS_INT
5233 range anyway (because otherwise the length would not be representable).
5234 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
5235 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
5236 This avoids a GCC warning when WIDE_EMACS_INT.
5237
5238 * indent.c (sane_tab_width): New function.
5239 (current_column, scan_for_column, Findent_to, position_indentation)
5240 (compute_motion): Use it. This is just for clarity.
5241 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
5242
5243 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
5244
5245 * lisp.h (lint_assume): New macro.
5246 * composite.c (composition_gstring_put_cache):
5247 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
5248
5249 * editfns.c, insdel.c:
5250 Omit unnecessary forward decls, to simplify future changes.
5251
5252 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
5253
5254 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
5255
5256 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
5257 Use much-faster test for byte-length change.
5258 Don't assume string byte-length fits in 'int'.
5259 Check that character arg fits in 'int'.
5260 (mapcar1): Declare byte as byte, for clarity.
5261
5262 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
5263
5264 * fns.c (concat): Catch string overflow earlier.
5265 Do not rely on integer wraparound.
5266
5267 * dispextern.h (struct it.overlay_strings_charpos)
5268 (struct it.selective): Now EMACS_INT, not int.
5269 * xdisp.c (forward_to_next_line_start)
5270 (back_to_previous_visible_line_start)
5271 (reseat_at_next_visible_line_start, next_element_from_buffer):
5272 Don't arbitrarily truncate the value of 'selective' to int.
5273
5274 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
5275
5276 * composite.c: Don't truncate sizes to 'int'.
5277 (composition_gstring_p, composition_reseat_it)
5278 (composition_adjust_point): Use EMACS_INT, not int.
5279 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
5280 not EMACS_UINT, for indexes.
5281
5282 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
5283
5284 * buffer.c: Include <verify.h>.
5285 (struct sortvec.priority, struct sortstr.priority):
5286 Now EMACS_INT, not int.
5287 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
5288 (struct sortstr.size, record_overlay_string)
5289 (struct sortstrlist.size, struct sortlist.used):
5290 Don't truncate size to int.
5291 (record_overlay_string): Check for size-calculation overflow.
5292 (init_buffer_once): Check at compile-time, not run-time.
5293
5294 2011-06-22 Jim Meyering <meyering@redhat.com>
5295
5296 Don't leak an XBM-image-sized buffer
5297 * image.c (xbm_load): Free the image buffer after using it.
5298
5299 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
5300
5301 Port to Sun C.
5302 * composite.c (find_automatic_composition): Omit needless 'return 0;'
5303 that Sun C diagnosed.
5304 * fns.c (secure_hash): Fix pointer signedness issue.
5305 * intervals.c (static_offset_intervals): New function.
5306 (offset_intervals): Use it.
5307
5308 2011-06-21 Leo Liu <sdl.web@gmail.com>
5309
5310 * deps.mk (fns.o):
5311 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
5312 sha512.h.
5313
5314 * fns.c (secure_hash): Rename from crypto_hash_function and change
5315 the first arg to accept symbols.
5316 (Fsecure_hash): New primitive.
5317 (syms_of_fns): New symbols.
5318
5319 2011-06-20 Deniz Dogan <deniz@dogan.se>
5320
5321 * process.c (Fset_process_buffer): Clarify return value in
5322 docstring.
5323
5324 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
5325
5326 * dispnew.c (add_window_display_history): Use BVAR.
5327
5328 * xdisp.c (debug_method_add): Use BVAR.
5329 (check_window_end, dump_glyph_matrix, dump_glyph)
5330 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
5331
5332 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
5333 Likewise.
5334
5335 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
5336 check till after the cache is created in init_frame_faces.
5337
5338 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
5339
5340 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
5341
5342 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
5343
5344 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
5345 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
5346 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
5347
5348 Improve buffer-overflow checking (Bug#8873).
5349 * fileio.c (Finsert_file_contents):
5350 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
5351 Remove the old (too-loose) buffer overflow checks.
5352 They weren't needed, since make_gap checks for buffer overflow.
5353 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
5354 The old code merely checked for Emacs fixnum overflow, and relied
5355 on undefined (wraparound) behavior. The new code avoids undefined
5356 behavior, and also checks for ptrdiff_t and/or size_t overflow.
5357
5358 * editfns.c (Finsert_char): Don't dump core with very negative counts.
5359 Tune. Don't use wider integers than needed. Don't use alloca.
5360 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
5361
5362 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
5363
5364 * insdel.c, lisp.h (buffer_overflow): New function.
5365 (insert_from_buffer_1, replace_range, replace_range_2):
5366 * insdel.c (make_gap_larger):
5367 * editfns.c (Finsert_char):
5368 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
5369
5370 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
5371
5372 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
5373
5374 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
5375
5376 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
5377 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
5378
5379 * fileio.c: Don't assume EMACS_INT fits in off_t.
5380 (emacs_lseek): New static function.
5381 (Finsert_file_contents, Fwrite_region): Use it.
5382 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
5383
5384 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
5385
5386 * fns.c: Don't overflow int when computing a list length.
5387 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
5388 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
5389 truncation on 64-bit hosts. Check for QUIT every
5390 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
5391 faster and is responsive enough.
5392 (Flength): Report an error instead of overflowing an integer.
5393 (Fsafe_length): Return a float if the value is not representable
5394 as a fixnum. This shouldn't happen except in contrived situations.
5395 (Fnthcdr, Fsort): Don't assume list length fits in int.
5396 (Fcopy_sequence): Don't assume vector length fits in int.
5397
5398 * alloc.c: Check that resized vectors' lengths fit in fixnums.
5399 (header_size, word_size): New constants.
5400 (allocate_vectorlike): Don't check size overflow here.
5401 (allocate_vector): Check it here instead, since this is the only
5402 caller of allocate_vectorlike that could cause overflow.
5403 Check that the new vector's length is representable as a fixnum.
5404
5405 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
5406 The previous code was bogus. For example, next_almost_prime (32)
5407 returned 39, which is undesirable as it is a multiple of 3; and
5408 next_almost_prime (24) returned 25, which is a multiple of 5 so
5409 why was the code bothering to check for multiples of 7?
5410
5411 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
5412
5413 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
5414
5415 Variadic C functions now count arguments with ptrdiff_t.
5416 This partly undoes my 2011-03-30 change, which replaced int with size_t.
5417 Back then I didn't know that the Emacs coding style prefers signed int.
5418 Also, in the meantime I found a few more instances where arguments
5419 were being counted with int, which may truncate counts on 64-bit
5420 machines, or EMACS_INT, which may be unnecessarily wide.
5421 * lisp.h (struct Lisp_Subr.function.aMANY)
5422 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
5423 Arg counts are now ptrdiff_t, not size_t.
5424 All variadic functions and their callers changed accordingly.
5425 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
5426 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
5427 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
5428 * callint.c (Fcall_interactively): Check arg count for overflow,
5429 to avoid potential buffer overrun. Use signed char, not 'int',
5430 for 'varies' array, so that we needn't bother to check its size
5431 calculation for overflow.
5432 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
5433 * eval.c (apply_lambda):
5434 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
5435 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
5436 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
5437
5438 * callint.c (Fcall_interactively): Don't use index var as event count.
5439
5440 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
5441 * mem-limits.h (SIZE): Remove; no longer used.
5442
5443 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
5444
5445 Remove unnecessary casts.
5446 * xterm.c (x_term_init):
5447 * xfns.c (x_set_border_pixel):
5448 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
5449 These aren't needed now that we assume ANSI C.
5450
5451 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
5452 It's more likely to cause problems (due to unsigned overflow)
5453 than to cure them.
5454
5455 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
5456
5457 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
5458
5459 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
5460
5461 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
5462
5463 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
5464
5465 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
5466
5467 GLYPH_CODE_FACE returns EMACS_INT, not int.
5468 * dispextern.h (merge_faces):
5469 * xfaces.c (merge_faces):
5470 * xdisp.c (get_next_display_element, next_element_from_display_vector):
5471 Don't assume EMACS_INT fits in int.
5472
5473 * character.h (CHAR_VALID_P): Remove unused parameter.
5474 * fontset.c, lisp.h, xdisp.c: All uses changed.
5475
5476 * editfns.c (Ftranslate_region_internal): Omit redundant test.
5477
5478 * fns.c (concat): Minor tuning based on overflow analysis.
5479 This doesn't fix any bugs. Use int to hold character, instead
5480 of constantly refetching from Emacs object. Use XFASTINT, not
5481 XINT, for value known to be a character. Don't bother comparing
5482 a single byte to 0400, as it's always less.
5483
5484 * floatfns.c (Fexpt):
5485 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
5486
5487 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
5488 for characters.
5489
5490 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
5491
5492 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
5493 Without this fix, on a 64-bit host (aset S 0 4294967386) would
5494 incorrectly succeed when S was a string, because 4294967386 was
5495 truncated before it was used.
5496
5497 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
5498 Otherwise, an out-of-range integer could cause undefined behavior
5499 on a 64-bit host.
5500
5501 * composite.c: Use int, not EMACS_INT, for characters.
5502 (fill_gstring_body, composition_compute_stop_pos): Use int, not
5503 EMACS_INT, for values that are known to be in character range.
5504 This doesn't fix any bugs but is the usual style inside Emacs and
5505 may generate better code on 32-bit machines.
5506
5507 Make sure a 64-bit char is never passed to ENCODE_CHAR.
5508 This is for reasons similar to the recent CHAR_STRING fix.
5509 * charset.c (Fencode_char): Check that character arg is actually
5510 a character. Pass an int to ENCODE_CHAR.
5511 * charset.h (ENCODE_CHAR): Verify that the character argument is no
5512 wider than 'int', as a compile-time check to prevent future regressions
5513 in this area.
5514
5515 * character.c (char_string): Remove unnecessary casts.
5516
5517 Make sure a 64-bit char is never passed to CHAR_STRING.
5518 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
5519 by silently ignoring the top 32 bits, allowing some values
5520 that were far too large to be valid characters.
5521 * character.h: Include <verify.h>.
5522 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
5523 arguments are no wider than unsigned, as a compile-time check
5524 to prevent future regressions in this area.
5525 * data.c (Faset):
5526 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
5527 (Fsubst_char_in_region):
5528 * fns.c (concat):
5529 * xdisp.c (decode_mode_spec_coding):
5530 Adjust to CHAR_STRING's new requirement.
5531 * editfns.c (Finsert_char, Fsubst_char_in_region):
5532 * fns.c (concat): Check that character args are actually
5533 characters. Without this test, these functions did the wrong
5534 thing with wildly out-of-range values on 64-bit hosts.
5535
5536 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
5537 These casts should not be needed on 32-bit hosts, either.
5538 * keyboard.c (read_char):
5539 * lread.c (Fload): Remove casts to unsigned.
5540
5541 * lisp.h (UNSIGNED_CMP): New macro.
5542 This fixes comparison bugs on 64-bit hosts.
5543 (ASCII_CHAR_P): Use it.
5544 * casefiddle.c (casify_object):
5545 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
5546 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
5547 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
5548 * dispextern.h (FACE_FROM_ID):
5549 * keyboard.c (read_char): Use UNSIGNED_CMP.
5550
5551 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
5552 not to EMACS_INT, to avoid GCC warning.
5553
5554 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
5555
5556 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
5557 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
5558 isn't needed on 32-bit machines.
5559
5560 * buffer.c (Fgenerate_new_buffer_name):
5561 Use EMACS_INT for count, not int.
5562 (advance_to_char_boundary): Return EMACS_INT, not int.
5563
5564 * data.c (Qcompiled_function): Now static.
5565
5566 * window.c (window_body_lines): Now static.
5567
5568 * image.c (gif_load): Rename local to avoid shadowing.
5569
5570 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
5571 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
5572 * alloc.c (make_save_value): Integer argument is now of type
5573 ptrdiff_t, not int.
5574 (mark_object): Use ptrdiff_t, not int.
5575 * lisp.h (pD): New macro.
5576 * print.c (print_object): Use it.
5577
5578 * alloc.c: Use EMACS_INT, not int, to count objects.
5579 (total_conses, total_markers, total_symbols, total_vector_size)
5580 (total_free_conses, total_free_markers, total_free_symbols)
5581 (total_free_floats, total_floats, total_free_intervals)
5582 (total_intervals, total_strings, total_free_strings):
5583 Now EMACS_INT, not int. All uses changed.
5584 (Fgarbage_collect): Compute overall total using a double, so that
5585 integer overflow is less likely to be a problem. Check for overflow
5586 when converting back to an integer.
5587 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
5588 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
5589 These were 'int' variables that could overflow on 64-bit hosts;
5590 they were never used, so remove them instead of repairing them.
5591 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
5592 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
5593 Previously, this ceilinged at INT_MAX, but that doesn't work on
5594 64-bit machines.
5595 (allocate_pseudovector): Don't use EMACS_INT when int would do.
5596
5597 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
5598 (allocate_vectorlike): Check for ptrdiff_t overflow.
5599 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
5600 when a (possibly-narrower) signed value would do just as well.
5601 We prefer using signed arithmetic, to avoid comparison confusion.
5602
5603 * alloc.c: Catch some string size overflows that we were missing.
5604 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
5605 for convenience in STRING_BYTES_MAX.
5606 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
5607 The definition here is exact; the one in lisp.h was approximate.
5608 (allocate_string_data): Check for string overflow. This catches
5609 some instances we weren't catching before. Also, it catches
5610 size_t overflow on (unusual) hosts where SIZE_MAX <= min
5611 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
5612 and ptrdiff_t and EMACS_INT are both 64 bits.
5613
5614 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
5615 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
5616 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
5617
5618 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
5619
5620 * alloc.c (Fmake_string): Check for out-of-range init.
5621

5623
5624 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
5625
5626 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>

5628 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
5629 xg_get_default_scrollbar_width.
5630

5649
5650 2011-06-12 Martin Rudalics <rudalics@gmx.at>
5651

5653 other_buffer.
5654
5655 * window.c (temp_output_buffer_show): Call display_buffer with
5656 second argument Vtemp_buffer_show_specifiers and reset latter
5657 immediately after the call.

6123 (LARGE_REQUEST): New macro, so that the issue of large requests
6124 is separated from the issue of spare memory.
6125

6184 display string.
6185 (bidi_paragraph_init, bidi_resolve_explicit_1)
6186 (bidi_level_of_next_char): Call bidi_fetch_char and

6193 instead of using explicit *_CHAR codes.
6194 (bidi_resolve_explicit, bidi_resolve_weak):
6195 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
6196 bidirectional text is supported only in multibyte buffers.

6205 were just reseat()'ed to a new position.
6206
6207 * xdisp.c (set_cursor_from_row): Set start and stop points
6208 according to the row's direction when priming the loop that looks

6211 (display_prop_intangible_p): Reimplement to call
6212 handle_display_spec instead of single_display_spec_intangible_p.
6213 Accept 3 additional arguments needed by handle_display_spec.
6214 This fixes incorrect cursor motion across display property with complex
6215 values: lists, `(when COND...)' forms, etc.
6216 (single_display_spec_string_p): Support property values that are
6217 lists with the argument STRING its top-level element.
6218 (display_prop_string_p): Fix the condition for processing a
6219 property that is a list to be consistent with handle_display_spec.

6221 last portion of handle_display_prop.
6222 (compute_display_string_pos): Accept additional argument

6224 value of a `display' property is a "replacing spec".
6225 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
6226 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

6254 All callers changed. (Bug#8762)
6255
6256 * gnutls.c: Use Emacs's memory allocators.
6257 Without this change, the gnutls library would invoke malloc etc.
6258 directly, which causes problems on non-SYNC_INPUT hosts, and which
6259 runs afoul of improving memory_full behavior. (Bug#8761)
6260 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
6261 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
6262 xfree instead of the default malloc, realloc, free.
6263 (Fgnutls_boot): No need to check for memory allocation failure,
6264 since xmalloc does that for us.
6265

6286 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
6287 for hashes and hash indexes, instead of 'unsigned' and 'int'.
6288 * alloc.c (allocate_vectorlike):
6289 Check for overflow in vector size calculations.
6290 * ccl.c (ccl_driver):
6291 Check for overflow when converting EMACS_INT to int.

6293 need to be updated by these changes.
6294 * fns.c (make_hash_table, maybe_resize_hash_table):
6295 Check for integer overflow with large hash tables.
6296 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
6297 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
6298 (SXHASH_REDUCE): New macro.
6299 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
6300 Use it instead of discarding useful hash info with large hash values.
6301 (sxhash_float): New function.
6302 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
6303 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
6304 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
6305 Rewrite to use FIXNUM_BITS, as this simplifies things.
6306 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
6307 Adjust signatures to match updated version of code.
6308 (consing_since_gc): Now EMACS_INT, since a single hash table can
6309 use more than INT_MAX bytes.
6310
6311 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
6312
6313 Make it possible to build with GCC-4.6+ -O2 -flto.
6314
6315 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
6316
6317 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
6318
6319 * minibuf.c (get_minibuffer, read_minibuf_unwind):

6321
6322 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
6323
6324 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
6325 Update dependencies.
6326
6327 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
6328
6329 * data.c (init_data): Remove code for UTS, this system is not
6330 supported anymore.
6331
6332 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
6333
6334 Don't force ./temacs to start in terminal mode.
6335
6336 * frame.c (make_initial_frame): Initialize faces in all cases, not
6337 only when CANNOT_DUMP is defined.

6339
6340 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
6341
6342 * dispnew.c (add_window_display_history): Use const for the string
6343 pointer. Remove declaration, not needed.
6344
6345 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
6346
6347 Use 'inline', not 'INLINE'.
6348 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
6349 * alloc.c, fontset.c (INLINE): Remove.
6350 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
6351 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
6352 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
6353 * gmalloc.c (register_heapinfo): Use inline unconditionally.
6354 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
6355
6356 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
6357
6358 Make it possible to run ./temacs.
6359
6360 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
6361 syms_of_callproc does the same thing. Remove test for
6362 "initialized", do it in the caller.
6363 * emacs.c (main): Avoid calling set_initial_environment when dumping.
6364
6365 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
6366
6367 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
6368 (read_minibuf): Use get_minibuffer.
6369 (syms_of_minibuf): Use DEFSYM.
6370 (Qmetadata): New var.
6371 * data.c (Qbuffer): Don't make it static.
6372 (syms_of_data): Use DEFSYM.
6373
6374 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
6375
6376 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
6377 (CCL_CODE_MIN): New macro.
6378
6379 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
6380
6381 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
6382
6383 * eval.c (Qdebug): Now static.
6384 * lisp.h (Qdebug): Remove decl. This reverts a part of the
6385 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
6386 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
6387
6388 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
6389
6390 * image.c: Various fixes to ImageMagick code comments.
6391 (Fimagemagick_types): Doc fix.
6392
6393 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
6394
6395 Minor fixes prompted by GCC 4.6.0 warnings.
6396
6397 * xselect.c (converted_selections, conversion_fail_tag): Now static.
6398
6399 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
6400 (x_clipboard_manager_save_all): Move extern decl to ...
6401 * xterm.h: ... here, so that it can be checked for consistency.
6402
6403 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
6404
6405 * xselect.c (x_clipboard_manager_save_frame)
6406 (x_clipboard_manager_save_all): New functions.
6407 (Fx_clipboard_manager_save): Lisp function deleted.
6408
6409 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
6410 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
6411
6412 * xterm.h: Update prototype.
6413
6414 2011-05-28 William Xu <william.xwl@gmail.com>
6415
6416 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
6417 exiting (Bug#8239).
6418
6419 2011-05-28 Jim Meyering <meyering@redhat.com>
6420
6421 Avoid a sign-extension bug in crypto_hash_function.
6422 * fns.c (to_uchar): Define.
6423 (crypto_hash_function): Use it to convert some newly-signed
6424 variables to unsigned, to avoid sign-extension bugs. For example,
6425 without this change, (md5 "truc") would evaluate to
6426 45723a2aff78ff4fff7fff1114760e62 rather than the expected
6427 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
6428 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
6429
6430 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
6431
6432 Integer overflow fixes.
6433
6434 * dbusbind.c: Serial number integer overflow fixes.
6435 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
6436 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
6437 to hold a serial number that is too large for a fixnum.
6438 (Fdbus_method_return_internal, Fdbus_method_error_internal):
6439 Check for serial numbers out of range. Decode any serial number
6440 that was so large that it became a float. (Bug#8722)
6441
6442 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
6443 (Fdbus_call_method, Fdbus_call_method_asynchronously):
6444 Use XFASTINT rather than XUINT when numbers are nonnegative.
6445 (xd_append_arg, Fdbus_method_return_internal):
6446 (Fdbus_method_error_internal): Likewise. Also, for unsigned
6447 arguments, check that Lisp number is nonnegative, rather than
6448 silently wrapping negative numbers around. (Bug#8722)
6449 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
6450 (Bug#8722)
6451
6452 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
6453
6454 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
6455
6456 ccl: Add integer overflow checks.
6457 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
6458 (IN_INT_RANGE): New macros.
6459 (ccl_driver): Use them to check for integer overflow when
6460 decoding a CCL program. Many of the new checks are whether XINT (x)
6461 fits in int; it doesn't always, on 64-bit hosts. The new version
6462 doesn't catch all possible integer overflows, but it's an
6463 improvement. (Bug#8719)
6464
6465 * alloc.c (make_event_array): Use XINT, not XUINT.
6466 There's no need for unsigned here.
6467
6468 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
6469 This follows up to the 2011-05-06 change that substituted uintptr_t
6470 for EMACS_INT. This case wasn't caught back then.
6471
6472 Rework Fformat to avoid integer overflow issues.
6473 * editfns.c: Include <float.h> unconditionally, as it's everywhere
6474 now (part of C89). Include <verify.h>.
6475 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
6476 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
6477 (Fformat): Avoid the prepass trying to compute sizes; it was only
6478 approximate and thus did not catch overflow reliably. Instead, walk
6479 through the format just once, formatting and computing sizes as we go,
6480 checking for integer overflow at every step, and allocating a larger
6481 buffer as needed. Keep track separately whether the format is
6482 multibyte. Keep only the most-recently calculated precision, rather
6483 than them all. Record whether each argument has been converted to
6484 string. Use EMACS_INT, not int, for byte and char and arg counts.
6485 Support field widths and precisions larger than INT_MAX. Avoid
6486 sprintf's undefined behavior with conversion specifications such as %#d
6487 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
6488 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
6489 formatting out-of-range floating point numbers with int
6490 formats. (Bug#8668)
6491
6492 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
6493
6494 * data.c: Avoid integer truncation in expressions involving floats.
6495 * data.c: Include <intprops.h>.
6496 (arith_driver): When there's an integer overflow in an expression
6497 involving floating point, convert the integers to floating point
6498 so that the resulting value does not suffer from catastrophic
6499 integer truncation. For example, on a 64-bit host (* 4
6500 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
6501 Do not rely on undefined behavior after integer overflow.
6502
6503 merge count_size_as_multibyte, parse_str_to_multibyte
6504 * character.c, character.h (count_size_as_multibyte):
6505 Rename from parse_str_to_multibyte; all uses changed.
6506 Check for integer overflow.
6507 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
6508 since it's now a duplicate of the other. This is more of
6509 a character than a buffer op, so better that it's in character.c.
6510 * fns.c, print.c: Adjust to above changes.
6511
6512 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
6513
6514 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
6515
6516 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
6517
6518 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
6519 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
6520 (x_clipboard_manager_save): Now static.
6521 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
6522
6523 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
6524 (crypto_hash_function): Now static.
6525 Fix pointer signedness problems. Avoid unnecessary initializations.
6526
6527 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
6528
6529 * termhooks.h (Vselection_alist): Make it terminal-local.
6530
6531 * terminal.c (create_terminal): Initialize it.
6532
6533 * xselect.c: Support for clipboard managers.
6534 (Vselection_alist): Move to termhooks.h as terminal-local var.
6535 (LOCAL_SELECTION): New macro.
6536 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
6537 (symbol_to_x_atom): Remove gratuitous arg.
6538 (x_handle_selection_request, lisp_data_to_selection_data)
6539 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
6540 (x_own_selection, x_get_local_selection, x_convert_selection):
6541 New arg, specifying work frame. Use terminal-local Vselection_alist.
6542 (some_frame_on_display): Delete unused function.
6543 (Fx_own_selection_internal, Fx_get_selection_internal)
6544 (Fx_disown_selection_internal, Fx_selection_owner_p)
6545 (Fx_selection_exists_p): New optional frame arg.
6546 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
6547 (x_handle_selection_clear): Don't treat other terminals with the
6548 same keyboard specially. Use the terminal-local Vselection_alist.
6549 (x_clear_frame_selections): Use Frun_hook_with_args.
6550
6551 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
6552
6553 * xterm.h: Add support for those atoms.
6554
6555 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
6556
6557 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
6558 (converted_selections, conversion_fail_tag): New global variables.
6559 (x_selection_request_lisp_error): Free the above.
6560 (x_get_local_selection): Remove unnecessary code.
6561 (x_reply_selection_request): Args changed; handle arbitrary array
6562 of converted selections stored in converted_selections.
6563 Separate the XChangeProperty and SelectionNotify steps.
6564 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
6565 (x_convert_selection): New function.
6566 (x_handle_selection_event): Simplify.
6567 (x_get_foreign_selection): Don't ignore incoming requests while
6568 waiting for an answer; this will fail when we implement
6569 SAVE_TARGETS, and seems unnecessary anyway.
6570 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
6571 (Vx_sent_selection_functions): Doc fix.
6572
6573 2011-05-26 Leo Liu <sdl.web@gmail.com>
6574
6575 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
6576
6577 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6578
6579 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
6580
6581 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
6582 for fringe update if it has periodic bitmap.
6583 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
6584 and fringe_bitmap_periodic_p.
6585
6586 * fringe.c (get_fringe_bitmap_data): New function.
6587 (draw_fringe_bitmap_1, update_window_fringes): Use it.
6588 (update_window_fringes): Record periodicity of fringe bitmap in glyph
6589 row. Mark glyph row for fringe update if periodicity changed.
6590
6591 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
6592 for fringe update unless it has periodic bitmap.
6593
6594 2011-05-25 Kenichi Handa <handa@m17n.org>
6595
6596 * xdisp.c (get_next_display_element): Set correct it->face_id for
6597 a static composition.
6598
6599 2011-05-24 Leo Liu <sdl.web@gmail.com>
6600
6601 * deps.mk (fns.o):
6602 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
6603
6604 * fns.c (crypto_hash_function, Fsha1): New function.
6605 (Fmd5): Use crypto_hash_function.
6606 (syms_of_fns): Add Ssha1.
6607
6608 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
6609
6610 * gnutls.c: Remove unused macros.
6611 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
6612 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
6613 Remove macros that are defined and never used.
6614 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
6615
6616 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
6617
6618 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.

6621 select.el.
6622
6623 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
6624
6625 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
6626
6627 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
6628
6629 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
6630
6631 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6632
6633 * dispnew.c (scrolling_window): Don't exclude the case that the
6634 last enabled row in the desired matrix touches the bottom boundary.
6635
6636 2011-05-21 Glenn Morris <rgm@gnu.org>
6637
6638 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
6639 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
6640 and add some more files.
6641
6642 2011-05-20 Eli Zaretskii <eliz@gnu.org>
6643
6644 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
6645 report_file_error introduced by the change from 2011-05-07.
6646
6647 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
6648
6649 * systime.h (Time): Define only if emacs is defined.
6650 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
6651 where the include path doesn't have X11/X.h by default. See
6652 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
6653
6654 2011-05-20 Kenichi Handa <handa@m17n.org>
6655
6656 * composite.c (find_automatic_composition): Fix previous change.
6657
6658 2011-05-20 Glenn Morris <rgm@gnu.org>
6659
6660 * lisp.mk: New file, split from Makefile.in.
6661 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
6662 (shortlisp): Remove.
6663 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
6664
6665 2011-05-19 Glenn Morris <rgm@gnu.org>
6666
6667 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
6668 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
6669 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
6670 (lisp): Set the order to that of loadup.el.
6671 (shortlisp): Make it a copy of $lisp.
6672 (SOME_MACHINE_LISP): Remove.
6673 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
6674 Use just $shortlisp, not $SOME_MACHINE_LISP too.
6675
6676 2011-05-18 Kenichi Handa <handa@m17n.org>
6677
6678 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
6679 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
6680 (find_automatic_composition): Mostly rewrite for efficiency.
6681
6682 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
6683
6684 * makefile.w32-in: Update dependencies.
6685
6686 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
6687
6688 * menu.c: Include limits.h (fixes the MS-Windows build broken by
6689 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
6690
6691 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
6692
6693 Fix some integer overflow issues, such as string length overflow.
6694
6695 * insdel.c (count_size_as_multibyte): Check for string overflow.
6696
6697 * character.c (lisp_string_width): Check for string overflow.
6698 Use EMACS_INT, not int, for string indexes and lengths; in
6699 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
6700 the resulting string length overflows an EMACS_INT; instead,
6701 report a string overflow if no precision given. When checking for
6702 precision exhaustion, use a check that cannot possibly have
6703 integer overflow. (Bug#8675)
6704 * character.h (lisp_string_width): Adjust to new signature.
6705
6706 * alloc.c (string_overflow): New function.
6707 (Fmake_string): Use it. This doesn't change behavior, but saves
6708 a few bytes and will simplify future changes.
6709 * character.c (string_escape_byte8): Likewise.
6710 * lisp.h (string_overflow): New decl.
6711
6712 Fixups, following up to the user-interface timestamp change.
6713 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
6714 for UI timestamps, instead of unsigned long.
6715 * msdos.c (mouse_get_pos): Likewise.
6716 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
6717 * w32gui.h (Time): Define by including "systime.h" rather than by
6718 declaring it ourselves. (Bug#8664)
6719
6720 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
6721 * image.c (clear_image_cache): Likewise.
6722
6723 * term.c (term_mouse_position): Don't assume time_t wraparound.
6724
6725 Be more systematic about user-interface timestamps.
6726 Before, the code sometimes used 'Time', sometimes 'unsigned long',
6727 and sometimes 'EMACS_UINT', to represent these timestamps.
6728 This change causes it to use 'Time' uniformly, as that's what X uses.
6729 This makes the code easier to follow, and makes it easier to catch
6730 integer overflow bugs such as Bug#8664.
6731 * frame.c (Fmouse_position, Fmouse_pixel_position):
6732 Use Time, not unsigned long, for user-interface timestamps.
6733 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
6734 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
6735 * keyboard.h (last_event_timestamp): Likewise.
6736 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
6737 * menu.h (xmenu_show): Likewise.
6738 * term.c (term_mouse_position): Likewise.
6739 * termhooks.h (struct input_event.timestamp): Likewise.
6740 (struct terminal.mouse_position_hook): Likewise.
6741 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
6742 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
6743 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
6744 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
6745 what it was before.
6746 * menu.h, termhooks.h: Include "systime.h", for Time.
6747
6748 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
6749 Don't assume that the difference between two unsigned long values
6750 can fit into an integer. At this point, we know button_down_time
6751 <= event->timestamp, so the difference must be nonnegative, so
6752 there's no need to cast the result if double-click-time is
6753 nonnegative, as it should be; check that it's nonnegative, just in
6754 case. This bug is triggered when events are more than 2**31 ms
6755 apart (about 25 days). (Bug#8664)
6756
6757 * xselect.c (last_event_timestamp): Remove duplicate decl.
6758 (x_own_selection): Remove needless cast to unsigned long.
6759
6760 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
6761 that always fit in int. Use a sentinel instead of a counter, to
6762 avoid a temp and to allay GCC's concerns about possible int overflow.
6763 * frame.h (struct frame): Use int for menu_bar_items_used
6764 instead of EMACS_INT, since it always fits in int.
6765
6766 * menu.c (grow_menu_items): Check for int overflow.
6767
6768 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
6769
6770 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
6771 Before, the code was not consistent. These values cannot exceed
6772 2**31 - 1 so there's no need to make them unsigned.
6773 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
6774 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
6775 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
6776 as modifiers.
6777 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
6778
6779 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
6780 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
6781 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
6782 presumably because the widths might not match.
6783
6784 * window.c (size_window): Avoid needless test at loop start.
6785
6786 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
6787
6788 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
6789
6790 2011-05-12 Drew Adams <drew.adams@oracle.com>
6791
6792 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
6793
6794 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6795
6796 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
6797 `width' to `bar_area_x' and `bar_area_width', respectively.
6798 (x_scroll_run): Take account of fringe background extension.
6799
6800 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
6801 Rename local vars `left' and `width' to `bar_area_x' and
6802 `bar_area_width', respectively.
6803 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
6804 background extension.
6805
6806 2011-05-10 Jim Meyering <meyering@redhat.com>
6807
6808 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
6809
6810 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
6811
6812 * image.c (Finit_image_library): Return t for built-in image types,
6813 like pbm and xbm. (Bug#8640)
6814
6815 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
6816
6817 * w32menu.c (set_frame_menubar): Fix submenu allocation.
6818
6819 2011-05-07 Eli Zaretskii <eliz@gnu.org>
6820
6821 * w32console.c (Fset_screen_color): Doc fix.
6822 (Fget_screen_color): New function.
6823 (syms_of_ntterm): Defsubr it.
6824
6825 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
6826 unlink the temporary file if Fcall_process didn't create it in the
6827 first place.
6828 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
6829 child process will be redirected to a file specified with `:file'.
6830 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
6831 cue to call_process_cleanup not to close that handle.
6832
6833 2011-05-07 Ben Key <bkey76@gmail.com>
6834
6835 * makefile.w32-in: The bootstrap-temacs rule now makes use of
6836 one of two shell specific rules, either bootstrap-temacs-CMD or
6837 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
6838 to the previous implementation of the bootstrap-temacs rule.
6839 The bootstrap-temacs-CMD rule is similar to the previous
6840 implementation of the bootstrap-temacs rule except that it
6841 makes use of the ESC_CFLAGS variable instead of the CFLAGS
6842 variable.
6843
6844 These changes, along with some changes to nt/configure.bat,
6845 nt/gmake.defs, and nt/nmake.defs, are required to extend my
6846 earlier fix to add support for --cflags and --ldflags options
6847 that include quotes so that it works whether make uses cmd or
6848 sh as the shell.
6849
6850 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
6851
6852 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
6853 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
6854 is a constant.
6855 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
6856 a string. Handle both cases.
6857 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
6858 (Fdbus_register_method): Use Qinvalid_function.
6859
6860 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
6861
6862 * makefile.w32-in: Update dependencies.
6863 (LISP_H): Add inttypes.h and stdin.h.
6864 (PROCESS_H): Add unistd.h.
6865
6866 2011-05-06 Eli Zaretskii <eliz@gnu.org>
6867
6868 * lread.c: Include limits.h (fixes the MS-Windows build broken by
6869 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
6870
6871 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
6872
6873 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
6874
6875 * term.c (vfatal): Remove stray call to va_end.
6876 It's not needed and the C Standard doesn't allow it here anyway.
6877
6878 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
6879 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
6880
6881 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
6882 bytes.
6883
6884 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
6885
6886 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
6887
6888 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
6889
6890 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
6891
6892 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
6893
6894 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
6895 * charset.c (Fdefine_charset_internal): Don't initialize
6896 charset.code_space[15]. The value was garbage, on hosts with
6897 32-bit int (Bug#8600).
6898
6899 * lread.c (read_integer): Be more consistent with string-to-number.
6900 Use string_to_number to do the actual conversion; this avoids
6901 rounding errors and fixes some other screwups. Without this fix,
6902 for example, #x1fffffffffffffff was misread as -2305843009213693952.
6903 (digit_to_number): Move earlier, for benefit of read_integer.
6904 Return -1 if the digit is out of range for the base, -2 if it is
6905 not a digit in any supported base. (Bug#8602)
6906
6907 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
6908
6909 * dispnew.c (scrolling_window): Return 1 if we scrolled,
6910 to match comment at start of function. This also removes a
6911 GCC warning about overflow in a 32+64-bit port.
6912
6913 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
6914
6915 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
6916 Reported by Stefan Monnier in
6917 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
6918 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
6919 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
6920
6921 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
6922 (EMACS_UINTPTR): Likewise, with uintptr_t.
6923
6924 * lisp.h: Prefer 64-bit EMACS_INT if available.
6925 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
6926 on 32-bit hosts that have 64-bit int, so that they can access
6927 large files.
6928 However, temporarily disable this change unless the temporary
6929 symbol WIDE_EMACS_INT is defined.
6930
6931 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
6932
6933 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
6934 This removes an assumption that EMACS_INT and long are the same
6935 width as pointers. The assumption is true for Emacs porting targets
6936 now, but we want to make other targets possible.
6937 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
6938 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
6939 In the rest of the code, change types of integers that hold casted
6940 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
6941 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
6942 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
6943 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
6944 No need to cast type when ORing.
6945 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
6946 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
6947 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
6948 assume EMACS_INT is the same width as char *.
6949 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
6950 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
6951 Remove no-longer-needed casts.
6952 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
6953 (xg_tool_bar_help_callback, xg_make_tool_item):
6954 Use EMACS_INTPTR to hold an integer
6955 that will be cast to void *; this can avoid a GCC warning
6956 if EMACS_INT is not the same width as void *.
6957 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
6958 * xdisp.c (display_echo_area_1, resize_mini_window_1):
6959 (current_message_1, set_message_1):
6960 Use a local to convert to proper width without a cast.
6961 * xmenu.c (dialog_selection_callback): Likewise.
6962
6963 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
6964 Also, don't assume VALBITS / RAND_BITS is less than 5,
6965 and don't rely on undefined behavior when shifting a 1 left into
6966 the sign bit.
6967 * lisp.h (get_random): Change signature to match.
6968
6969 * lread.c (hash_string): Use size_t, not int, for hash computation.
6970 Normally we prefer signed values; but hashing is special, because
6971 it's better to use unsigned division on hash table sizes so that
6972 the remainder is nonnegative. Also, size_t is the natural width
6973 for hashing into memory. The previous code used 'int', which doesn't
6974 retain enough info to hash well into very large tables.
6975 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
6976
6977 * dbusbind.c: Don't possibly lose pointer info when converting.
6978 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
6979 Use XPNTR rather than XHASH, so that the high-order bits of
6980 the pointer aren't lost when converting through void *.
6981
6982 * eval.c (Fautoload): Don't double-shift a pointer.
6983
6984 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
6985
6986 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
6987
6988 * gnutls.c (DEF_GNUTLS_FN):
6989 * image.c (DEF_IMGLIB_FN): Make function pointers static.
6990
6991 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
6992
6993 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
6994 marker. (Bug#8610)
6995
6996 2011-05-05 Eli Zaretskii <eliz@gnu.org>
6997

7016
7017 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
7018 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
7019 Remove unused parameter `fildes'.
7020 * process.c (read_process_output, send_process): Don't pass it.
7021
7022 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
7023
7024 Fix previous change: the library cache is defined in w32.c.
7025 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
7026 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
7027
7028 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
7029
7030 Implement dynamic loading of GnuTLS on Windows.

7034 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
7035 Declare.
7036
7037 * gnutls.c (Qgnutls_dll): Define.
7038 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
7039 (gnutls_*): Declare function pointers.
7040 (init_gnutls_functions): New function to initialize function pointers.
7041 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
7042 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
7043 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
7044 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
7045 (emacs_gnutls_write, emacs_gnutls_read)
7046 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
7047 (Fgnutls_available_p): New function.

7050 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
7051
7052 * image.c: Include w32.h.
7053 (Vimage_type_cache): Delete.
7054 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
7055 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
7056 (w32_delayed_load): Move to w32.c.
7057
7058 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
7059
7060 * w32.c (QCloaded_from, Vlibrary_cache): Define.
7061 (w32_delayed_load): Move from image.c. When loading a library, record
7062 its filename in the :loaded-from property of the library id.
7063 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
7064 Initialize and staticpro them.
7065 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
7066
7067 * process.c: Include lisp.h before w32.h, not after.
7068 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
7069 instead of gnutls_record_check_pending.
7070
7071 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.

7097 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
7098 (Qgnutls_bootprop_callbacks_verify): Make static.
7099
7100 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
7101
7102 * callproc.c: Indentation fixup.
7103
7104 * sysdep.c (wait_for_termination_1): Make static.
7105 (wait_for_termination, interruptible_wait_for_termination):

7107
7108 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
7109
7110 * sysdep.c (interruptible_wait_for_termination): New function
7111 which is like wait_for_termination, but allows keyboard
7112 interruptions.
7113
7114 * callproc.c (Fcall_process): Add (:file "file") as an option for
7115 the STDOUT buffer.
7116 (Fcall_process_region): Ditto.
7117

7119
7120 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
7121 rather than `XVECTOR (FOO)->size'.
7122
7123 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
7124 inttypes.h, as a gnulib replacement is used if it not available in
7125 system headers.
7126
7127 2011-04-21 Eli Zaretskii <eliz@gnu.org>
7128
7129 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

7131 of MOST_POSITIVE_FIXNUM. (Bug#8528)
7132
7133 * coding.c (coding_alloc_by_realloc): Error out if destination
7134 will grow beyond MOST_POSITIVE_FIXNUM.
7135 (decode_coding_emacs_mule): Abort if there isn't enough place in
7136 charbuf for the composition carryover bytes. Reserve an extra
7137 space for up to 2 characters produced in a loop.
7138 (decode_coding_iso_2022): Abort if there isn't enough place in
7139 charbuf for the composition carryover bytes.
7140
7141 2011-04-21 Eli Zaretskii <eliz@gnu.org>
7142
7143 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
7144 aborting when %lld or %lll format is passed.
7145 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
7146 %llo or %llx format is passed. (Bug#8545)
7147
7148 * window.c (window_scroll_line_based): Use a marker instead of
7149 simple variables to record original value of point. (Bug#7952)
7150
7151 * doprnt.c (doprnt): Fix the case where a multibyte sequence
7152 produced by %s or %c overflows available buffer space. (Bug#8545)
7153
7154 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
7155
7156 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
7157 (SIZE_MAX): Move defn after all includes, as they might #define it.
7158
7159 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
7160
7161 * w32.c (init_environment): Warn about defaulting HOME to C:\.
7162
7163 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
7164
7165 * keyboard.c (Qdelayed_warnings_hook): Define.
7166 (command_loop_1): Run `delayed-warnings-hook'
7167 if Vdelayed_warnings_list is non-nil.
7168 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
7169 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
7170
7171 2011-04-28 Eli Zaretskii <eliz@gnu.org>
7172
7173 * doprnt.c (doprnt): Don't return value smaller than the buffer
7174 size if the message was truncated. (Bug#8545).
7175
7176 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
7177
7178 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
7179 (Fx_window_property): #if-0 the whole functions, not just the bodies.
7180
7181 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
7182
7183 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
7184
7185 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
7186
7187 * makefile.w32-in: Update dependencies.
7188
7189 2011-04-27 Eli Zaretskii <eliz@gnu.org>
7190
7191 Improve `doprnt' and its usage. (Bug#8545)
7192 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
7193 `format_end'. Remove support for %l as a conversion specifier.
7194 Don't use xrealloc. Improve diagnostics when the %l size modifier
7195 is used. Update the commentary.
7196
7197 * eval.c (verror): Simplify calculation of size_t.
7198
7199 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
7200 messages.
7201
7202 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
7203
7204 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
7205 change.
7206
7207 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
7208
7209 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
7210 This makes this file independent of the recent pseudovector change.
7211
7212 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
7213
7214 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
7215
7216 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
7217 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
7218 Remove unused local.
7219 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
7220
7221 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
7222 GCC 4.6.0 optimizes based on type-based alias analysis.
7223 For example, if b is of type struct buffer * and v of type struct
7224 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
7225 != &v->size, and therefore "v->size = 1; b->size = 2; return
7226 v->size;" must therefore return 1. This assumption is incorrect
7227 for Emacs, since it type-puns struct Lisp_Vector * with many other
7228 types. To fix this problem, this patch adds a new type struct
7229 vectorlike_header that documents the constraints on layout of vectors
7230 and pseudovectors, and helps optimizing compilers not get fooled
7231 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
7232 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
7233 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
7234 the size member.
7235 (XSETPVECTYPE): Rewrite in terms of new macro.
7236 (XSETPVECTYPESIZE): New macro, specifying both type and size.
7237 This is a bit clearer, and further avoids the possibility of
7238 undesirable aliasing.
7239 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
7240 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
7241 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
7242 since Lisp_Subr is a special case (no "next" field).
7243 (ASIZE): Now uses header.size rather than size.
7244 All previous uses of XVECTOR (foo)->size replaced to use this macro,
7245 to avoid the hassle of writing XVECTOR (foo)->header.size.
7246 (struct vectorlike_header): New type.
7247 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
7248 object, to help avoid aliasing.
7249 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
7250 (SUBRP): Likewise, since Lisp_Subr is a special case.
7251 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
7252 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
7253 (struct Lisp_Hash_Table): Combine first two members into a single
7254 struct vectorlike_header member. All uses of "size" and "next" members
7255 changed to be "header.size" and "header.next".
7256 * buffer.h (struct buffer): Likewise.
7257 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
7258 * frame.h (struct frame): Likewise.
7259 * process.h (struct Lisp_Process): Likewise.
7260 * termhooks.h (struct terminal): Likewise.
7261 * window.c (struct save_window_data, struct saved_window): Likewise.
7262 * window.h (struct window): Likewise.
7263 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
7264 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
7265 * buffer.c (init_buffer_once): Likewise.
7266 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
7267 special case.
7268 * process.c (Fformat_network_address): Use local var for size,
7269 for brevity.
7270
7271 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
7272
7273 Make the Lisp reader and string-to-float more consistent (Bug#8525)
7274 * data.c (atof): Remove decl; no longer used or needed.
7275 (digit_to_number): Move to lread.c.
7276 (Fstring_to_number): Use new string_to_number function, to be
7277 consistent with how the Lisp reader treats infinities and NaNs.
7278 Do not assume that floating-point numbers represent EMACS_INT
7279 without losing information; this is not true on most 64-bit hosts.
7280 Avoid double-rounding errors, by insisting on integers when
7281 parsing non-base-10 numbers, as the documentation specifies.
7282 * lisp.h (string_to_number): New decl, replacing ...
7283 (isfloat_string): Remove.
7284 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
7285 (read1): Do not accept +. and -. as integers; this
7286 appears to have been a coding error. Similarly, do not accept
7287 strings like +-1e0 as floating point numbers. Do not report
7288 overflow for integer overflows unless the base is not 10 which
7289 means we have no simple and reliable way to continue.
7290 Break out the floating-point parsing into a new
7291 function string_to_number, so that Fstring_to_number parses
7292 floating point numbers consistently with the Lisp reader.
7293 (digit_to_number): Move here from data.c. Make it static inline.
7294 (E_CHAR, EXP_INT): Remove, replacing with ...
7295 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
7296 (string_to_number): New function, replacing isfloat_string.
7297 This function checks for valid syntax and produces the resulting
7298 Lisp float number too. Rework it so that string-to-number
7299 no longer mishandles examples like "1.0e+". Use strtoumax,
7300 so that overflow for non-base-10 numbers is reported only when
7301 there's no portable and simple way to convert to floating point.
7302
7303 * textprop.c (set_text_properties_1): Rewrite for clarity,
7304 and to avoid GCC warning about integer overflow.
7305
7306 * intervals.h (struct interval): Use EMACS_INT for members
7307 where EMACS_UINT might cause problems. See
7308 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
7309 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
7310 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
7311 All uses changed.
7312 (offset_intervals): Tell GCC not to worry about length overflow
7313 when negating a negative length.
7314
7315 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
7316 (overrun_check_free): Likewise.
7317
7318 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
7319 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
7320 word size.
7321
7322 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
7323 (gnutls_make_error): Rename local to avoid shadowing.
7324 (gnutls_emacs_global_deinit): ifdef out; not used.
7325 (Fgnutls_boot): Use const for pointer to readonly storage.
7326 Comment out unused local. Fix pointer signedness problems.
7327
7328 * lread.c (openp): Don't stuff size_t into an 'int'.
7329 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
7330 about possible signed overflow.
7331
7332 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
7333 (GDK_KEY_g): Don't define if already defined.
7334 (xg_prepare_tooltip): Avoid pointer signedness problem.
7335 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
7336
7337 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
7338 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
7339
7340 * xfns.c (Fx_window_property): Simplify a bit,
7341 to make a bit faster and to avoid GCC 4.6.0 warning.
7342 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
7343
7344 * fns.c (internal_equal): Don't assume size_t fits in int.
7345
7346 * alloc.c (compact_small_strings): Tighten assertion a little.
7347
7348 Replace pEd with more-general pI, and fix some printf arg casts.
7349 * lisp.h (pI): New macro, generalizing old pEd macro to other
7350 conversion specifiers. For example, use "...%"pI"d..." rather
7351 than "...%"pEd"...".
7352 (pEd): Remove. All uses replaced with similar uses of pI.
7353 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
7354 * alloc.c (check_pure_size): Don't overflow by converting size to int.
7355 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
7356 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
7357 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
7358 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
7359 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
7360 64-bit hosts.
7361 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
7362 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
7363 * print.c (safe_debug_print, print_object): Likewise.
7364 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
7365 to int.
7366 Use pI instead of if-then-else-abort. Use %p to avoid casts,
7367 avoiding the 0 flag, which is not portable.
7368 * process.c (Fmake_network_process): Use pI to avoid cast.
7369 * region-cache.c (pp_cache): Likewise.
7370 * xdisp.c (decode_mode_spec): Likewise.
7371 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
7372 behavior on 64-bit hosts with printf arg.
7373 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
7374 (x_stop_queuing_selection_requests): Likewise.
7375 (x_get_window_property): Don't truncate byte count to an 'int'
7376 when tracing.
7377
7378 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
7379 here, since it parses constructs like leading '-' and spaces,
7380 which are not wanted; and it overflows with large numbers.
7381 Instead, simply match F[0-9]+, which is what is wanted anyway.
7382
7383 * alloc.c: Remove unportable assumptions about struct layout.
7384 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
7385 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
7386 (allocate_vectorlike, make_pure_vector): Use the new macros,
7387 plus offsetof, to remove unportable assumptions about struct layout.
7388 These assumptions hold on all porting targets that I know of, but
7389 they are not guaranteed, they're easy to remove, and removing them
7390 makes further changes easier.
7391
7392 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
7393 This doesn't fix a bug but makes the code clearer.
7394 (string_overrun_cookie): Now const. Use initializers that
7395 don't formally overflow signed char, to avoid warnings.
7396 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
7397 can cause Emacs to crash when string overrun checking is enabled.
7398 (allocate_buffer): Don't assume sizeof (struct buffer) is a
7399 multiple of sizeof (EMACS_INT); it need not be, if
7400 alignof(EMACS_INT) < sizeof (EMACS_INT).
7401 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
7402
7403 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
7404
7405 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
7406
7407 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
7408
7409 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
7410 supposed to be handshaking. (Bug#8556)
7411 Reported by Paul Eggert <eggert@cs.ucla.edu>.
7412
7413 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
7414
7415 * lisp.h (Qdebug): List symbol.
7416 * eval.c (Qdebug): Restore global linkage.
7417 * keyboard.c (debug-on-event): New variable.
7418 (handle_user_signal): Break into debugger when debug-on-event
7419 matches the current signal symbol.
7420
7421 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
7422
7423 * alloc.c (check_sblock, check_string_bytes)
7424 (check_string_free_list): Convert to standard C.
7425
7426 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
7427
7428 * w32.c (emacs_gnutls_push): Fix typo.
7429
7430 2011-04-25 Eli Zaretskii <eliz@gnu.org>
7431
7432 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
7433 "cast to pointer from integer of different size".
7434
7435 Improve doprnt and its use in verror. (Bug#8545)
7436 * doprnt.c (doprnt): Document the set of format control sequences
7437 supported by the function. Use SAFE_ALLOCA instead of always
7438 using `alloca'.
7439
7440 * eval.c (verror): Don't limit the buffer size at size_max-1, that
7441 is one byte too soon. Don't use xrealloc; instead xfree and
7442 xmalloc anew.
7443
7444 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
7445
7446 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
7447 callbacks stage.
7448
7449 * gnutls.c: Renamed global_initialized to
7450 gnutls_global_initialized. Added internals for the
7451 :verify-hostname-error, :verify-error, and :verify-flags
7452 parameters of `gnutls-boot' and documented those parameters in the
7453 docstring. Start callback support.
7454 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
7455 unless a fatal error occurred. Call gnutls_alert_send_appropriate
7456 on error. Return error code.
7457 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
7458 (emacs_gnutls_read): Likewise.
7459 (Fgnutls_boot): Return handshake error code.
7460 (emacs_gnutls_handle_error): New function.
7461 (wsaerror_to_errno): Likewise.
7462

7464 (emacs_gnutls_push): Likewise.
7465
7466 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
7467 (emacs_gnutls_push): Likewise.
7468
7469 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
7470
7471 * process.c (wait_reading_process_output): Check if GnuTLS
7472 buffered some data internally if no FDs are set for TLS
7473 connections.
7474
7475 * makefile.w32-in (OBJ2): Add gnutls.$(O).
7476 (LIBS): Link to USER_LIBS.

7478
7479 2011-04-24 Eli Zaretskii <eliz@gnu.org>
7480
7481 * xdisp.c (handle_single_display_spec): Rename the
7482 display_replaced_before_p argument into display_replaced_p, to
7483 make it consistent with the commentary. Fix typos in the
7484 commentary.
7485
7486 * textprop.c (syms_of_textprop): Remove dead code.
7487 (copy_text_properties): Delete obsolete commentary about an
7488 interface that was deleted long ago. Fix typos in the description
7489 of arguments.
7490
7491 * msdos.c (XMenuActivate, XMenuAddSelection): Adjust argument list
7492 to changes in oldXMenu/XMenu.h from 2011-04-16.
7493 <menu_help_message, prev_menu_help_message>: Constify.
7494 (IT_menu_make_room): menu->help_text is now `const char **';
7495 adjust.
7496
7497 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
7498 to changes in oldXMenu/XMenu.h from 2011-04-16.
7499 (struct XMenu): Declare `help_text' `const char **'.
7500
7501 * xfaces.c <Qunspecified>: Make extern again.
7502
7503 * syntax.c: Include sys/types.h before including regex.h, as
7504 required by Posix.
7505
7506 * doc.c (get_doc_string): Improve the format passed to `error'.
7507
7508 * doprnt.c (doprnt): Improve commentary.
7509
7510 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
7511
7512 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
7513 them with etags.
7514
7515 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
7516 changes in globals.h immediately force recompilation.

7983 * fontset.h (face_suitable_for_char_p): Remove decl.
7984 * xfaces.c (face_at_string_position):
7985 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,

8009 * editfns.c, lisp.h (get_operating_system_release): Remove.
8010 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
8011 worth the hassle of breaking this out.
8012
8013 * xterm.c: Make symbols static if they're not exported.
8014 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

8120 so that it's not optimized away.
8121 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
8122 * dispextern.h (bidi_dump_cached_states): Remove, since it's
8123 exported only to the debugger.
8124
8125 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
8126 * atimer.h (run_all_atimers): Remove; not exported.
8127
8128 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
8129 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
8130 was inaccessible from Lisp.

8133
8134 alloc.c: Import and export fewer symbols, and remove unused items.
8135 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
8136 is defined.

8138 it's not optimized away by whole-program optimization.

8156 to see whether these variables are used from other modules.
8157 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

8168 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
8169
8170 * lisp.h (DEFINE_FUNC): Make sname 'static'.
8171
8172 Make Emacs functions such as Fatom 'static' by default.
8173 This makes it easier for human readers (and static analyzers)
8174 to see whether these functions can be called from other modules.
8175 DEFUN now defines a static function. To make the function external
8176 so that it can be used in other C modules, use the new macro DEFUE.
8177 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
8178 (Finit_image_library):
8179 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
8180 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
8181 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
8182 Remove decls, since these functions are now static.
8183 (Funintern, Fget_internal_run_time): New decls, since these functions
8184 were already external.
8185
8186 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
8187 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

8192 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
8193 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
8194 Mark functions with DEFUE instead of DEFUN,
8195 if they are used in other modules.
8196 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
8197 decls for now-static functions.
8198 * buffer.h (Fdelete_overlay): Remove decl.

8212 * keyboard.c (Fthis_command_keys): Remove decl.
8213 (Fcommand_execute): New forward static decl.
8214 * keymap.c (Flookup_key): New forward static decl.
8215 (Fcopy_keymap): Now static.

8225 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
8226
8227 * editfns.c (Fformat): Remove unreachable code.
8228
8229 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
8230
8231 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
8232 change. (Bug#8496)
8233
8234 2011-04-13 Eli Zaretskii <eliz@gnu.org>
8235
8236 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
8237 when at ZV. (Bug#8487)
8238
8239 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
8240
8241 * charset.c (Fclear_charset_maps): Use xfree instead of free.

8243 * keyboard.c (parse_tool_bar_item): Likewise.
8244 * sound.c (sound_cleanup, alsa_close): Likewise.

8250 (overrun_check_free): Protoize.
8251
8252 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
8253
8254 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
8255 since callers should never pass a negative size.
8256 Change the signature to match that of plain 'read' and 'write'; see
8257 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
8258 * lisp.h: Update prototypes of emacs_write and emacs_read.
8259
8260 2011-04-11 Eli Zaretskii <eliz@gnu.org>
8261
8262 * xdisp.c (redisplay_window): Don't try to determine the character
8263 position of the scroll margin if the window start point w->startp
8264 is outside the buffer's accessible region. (Bug#8468)
8265
8266 2011-04-10 Eli Zaretskii <eliz@gnu.org>
8267
8268 Fix write-region and its subroutines for buffers > 2GB.
8269 * fileio.c (a_write, e_write): Modify declaration of arguments and
8270 local variables to support buffers larger than 2GB.
8271 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
8272
8273 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
8274 argument, local variables, and return value.
8275
8276 * lisp.h: Update prototypes of emacs_write and emacs_read.
8277
8278 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
8279
8280 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
8281
8282 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
8283
8284 Fix more problems found by GCC 4.6.0's static checks.
8285
8286 * xdisp.c (vmessage): Use a better test for character truncation.
8287
8288 * charset.c (load_charset_map): <, not <=, for optimization,
8289 and to avoid potential problems with integer overflow.
8290 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
8291 * casetab.c (set_identity, shuffle): Likewise.
8292 * editfns.c (Fformat): Likewise.
8293 * syntax.c (skip_chars): Likewise.
8294
8295 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
8296 This also lets GCC 4.6.0 generate slightly better loop code.
8297
8298 * callint.c (Fcall_interactively): <, not <=, for optimization.
8299 (Fcall_interactively): Count the number of arguments produced,
8300 not the number of arguments given. This is simpler and lets GCC
8301 4.6.0 generate slightly better code.
8302
8303 * ftfont.c: Distingish more carefully between FcChar8 and char.
8304 The previous code passed unsigned char * to a functions like
8305 strlen and xstrcasecmp that expect char *, which does not
8306 conform to the C standard.
8307 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
8308 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
8309 char * when the C standard requires it.
8310
8311 * keyboard.c (read_char): Remove unused var.
8312
8313 * eval.c: Port to Windows vsnprintf (Bug#8435).
8314 Include <limits.h>.
8315 (SIZE_MAX): Define if the headers do not.
8316 (verror): Do not give up if vsnprintf returns a negative count.
8317 Instead, grow the buffer. This ports to Windows vsnprintf, which
8318 does not conform to C99. Problem reported by Eli Zaretskii.
8319 Also, simplify the allocation scheme, by avoiding the need for
8320 calling realloc, and removing the ALLOCATED variable.
8321
8322 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
8323
8324 Remove invocations of doprnt, as Emacs now uses vsnprintf.
8325 But keep the doprint source code for now, as we might revamp it
8326 and use it again (Bug#8435).
8327 * lisp.h (doprnt): Remove.
8328 * Makefile.in (base_obj): Remove doprnt.o.
8329 * deps.mk (doprnt.o): Remove.
8330
8331 error: Print 32- and 64-bit integers portably (Bug#8435).
8332 Without this change, on typical 64-bit hosts error ("...%d...", N)
8333 was used to print both 32- and 64-bit integers N, which relied on
8334 undefined behavior.
8335 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
8336 * lisp.h (error, verror): Mark as printf-like functions.
8337 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
8338 Report overflow in size calculations when allocating printf buffer.
8339 Do not truncate output string at its first null byte.
8340 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
8341 Truncate the output at a character boundary, since vsnprintf does not
8342 do that.
8343 * charset.c (check_iso_charset_parameter): Convert internal
8344 character to string before calling 'error', since %c now has the
8345 printf meaning.
8346 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
8347 overflow when computing char to be passed to 'error'. Do not
8348 pass Lisp_Object to 'error'; pass the integer instead.

8490 some unnecessary tests.
8491 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
8492 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
8493 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

8507 by using the new macro.
8508
8509 * textprop.c (set_text_properties_1): Change while to do-while,
8510 since the condition is always true at first.
8511
8512 * intervals.c (graft_intervals_into_buffer): Mark var as used.

8535 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
8536
8537 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
8538 (font_score): Avoid potential overflow in diff calculation.
8539
8540 * fns.c (substring_both): Remove var that is set but not used.

8542
8543 * eval.c (funcall_lambda): Rename local to avoid shadowing.
8544
8545 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
8546 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
8547 can always succeed if overflow has undefined behavior.
8548
8549 * search.c (boyer_moore, wordify): Remove vars set but not used.
8550 (wordify): Omit three unnecessary tests.
8551

8578 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
8579
8580 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
8581 that are set but not used.
8582
8583 * xfns.c (make_invisible_cursor): Don't return garbage
8584 if XCreateBitmapFromData fails (Bug#8410).
8585
8586 * xselect.c (x_get_local_selection, x_handle_property_notify):
8587 Remove vars that are set but not used.
8588

8595 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
8596 Check for overflow.
8597
8598 * xfaces.c (realize_named_face): Remove vars that are set but not used.
8599 (map_tty_color) [!defined MSDOS]: Likewise.
8600
8601 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
8602
8603 * coding.c: Remove vars that are set but not used.
8604 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
8605 All callers changed.
8606 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
8607 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
8608 (decode_coding_charset): Remove vars that are set but not used.

8613 * print.c (print_object): Remove var that is set but not used.
8614
8615 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
8616 The gnulib version avoids calling malloc in the usual case,
8617 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
8618 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
8619 * filelock.c (current_lock_owner): Likewise.
8620 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
8621 * sysdep.c: Include allocator.h, careadlinkat.h.
8622 (emacs_no_realloc_allocator): New static constant.
8623 (emacs_readlink): New function.
8624 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
8625 ../lib/careadlinkat.h.

8628
8629 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
8630 first non-nil return value).
8631
8632 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
8633
8634 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
8635 if not defined (Bug#8403).
8636
8637 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
8638
8639 * xdisp.c (display_count_lines): Remove parameter `start',
8640 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

8682
8683 * keyboard.c (eval_dyn): New fun.
8684 (menu_item_eval_property): Use it.
8685
8686 * image.c (parse_image_spec): Use Ffunctionp.
8687
8688 * fns.c (concat, mapcar1): Accept byte-code-functions.
8689
8690 * eval.c (Fsetq): Handle lexical vars.
8691 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
8692 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
8693 (FletX, Flet): Obey lexical binding.
8694 (Fcommandp): Handle closures.
8695 (Feval): New `lexical' arg.
8696 (eval_sub): New function extracted from Feval. Use it almost
8697 everywhere where Feval was used. Look up vars in lexical env.
8698 Handle closures.
8699 (Ffunctionp): Move from subr.el.
8700 (Ffuncall): Handle closures.
8701 (apply_lambda): Remove `eval_flags'.
8702 (funcall_lambda): Handle closures and new byte-code-functions.
8703 (Fspecial_variable_p): New function.
8704 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
8705 but without exporting it to Lisp.
8706
8707 * doc.c (Fdocumentation, store_function_docstring):
8708 * data.c (Finteractive_form): Handle closures.
8709
8710 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
8711 interactive spec.

8729 (try_scrolling): Use it when setting scroll_limit.
8730 Limit scrolling to 100 screen lines.
8731 (redisplay_window): Even when falling back on "recentering",
8732 position point in the window according to scroll-conservatively,
8733 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
8734
8735 (try_scrolling): When point is above the window, allow searching
8736 as far as scroll_max, or one screenful, to compute vertical
8737 distance from PT to the scroll margin position. This prevents
8738 try_scrolling from unnecessarily failing when
8739 scroll-conservatively is set to a value slightly larger than the
8740 window height. Clean up the case of PT below the margin at bottom
8741 of window: scroll_max can no longer be INT_MAX. When aggressive
8742 scrolling is in use, don't let point enter the opposite scroll
8743 margin as result of the scroll.
8744 (syms_of_xdisp) <scroll-conservatively>: Document the
8745 threshold of 100 lines for never-recentering scrolling.
8746

8756
8757 * indent.c (Fvertical_motion):
8758 * window.c (window_scroll_pixel_based, Frecenter):
8759 Don't pass `need_y_p' to `move_it_by_lines'.

8761 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
8762
8763 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
8764 steal a few bits to be more compact.
8765 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
8766 Remove unneeded casts.
8767
8768 * bytecode.c (Fbyte_code): CAR and CDR can GC.
8769
8770 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
8771
8772 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
8773 binding" message (bug#7967).
8774
8775 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
8776
8777 Fix more problems found by GCC 4.6.0's static checks.
8778
8779 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
8780 Remove unused local var.
8781
8782 * editfns.c (Fmessage_box): Remove unused local var.
8783
8784 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
8785 (note_mode_line_or_margin_highlight, note_mouse_highlight):
8786 Omit unused local vars.
8787 * window.c (shrink_windows): Omit unused local var.
8788 * menu.c (digest_single_submenu): Omit unused local var.
8789 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
8790 Omit unused local var.
8791
8792 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
8793 Don't assume string length fits in int.
8794 (keyremap_step, read_key_sequence): Use size_t for sizes.
8795 (read_key_sequence): Don't check last_real_key_start redundantly.
8796
8797 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
8798 instead of alloca (Bug#8344).
8799
8800 * eval.c (Fbacktrace): Don't assume nargs fits in int.
8801 (Fbacktrace_frame): Don't assume nframes fits in int.
8802
8803 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
8804
8805 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
8806 concerns.
8807
8808 * term.c (produce_glyphless_glyph): Remove unnecessary test.
8809
8810 * cm.c (calccost): Turn while-do into do-while, for clarity.
8811
8812 * keyboard.c (syms_of_keyboard): Use the same style as later
8813 in this function when indexing through an array. This also
8814 works around GCC bug 48267.
8815
8816 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
8817

8821 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
8822
8823 * keyboard.c, keyboard.h (num_input_events): Now size_t.
8824 This avoids undefined behavior on integer overflow, and is a bit
8825 more convenient anyway since it is compared to a size_t variable.
8826
8827 Variadic C functions now count arguments with size_t, not int.
8828 This avoids an unnecessary limitation on 64-bit machines, which
8829 caused (substring ...) to crash on large vectors (Bug#8344).
8830 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
8831 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

8839 * fns.c (concat): Likewise.
8840 * frame.c (x_set_frame_parameters): Likewise.
8841 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
8842 0 if not found, not -1. All callers changed.
8843
8844 * alloc.c (garbage_collect): Don't assume stack size fits in int.
8845 (stack_copy_size): Now size_t, not int.
8846 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

8852 All callers changed.
8853
8854 * lisp.h (multibyte_char_to_unibyte):
8855 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
8856 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

8858 * cmds.c (internal_self_insert):
8859 * editfns.c (general_insert_function):
8860 * keymap.c (push_key_description):
8861 * search.c (Freplace_match):
8862 * xdisp.c (message_dolog, set_message_1): All callers changed.
8863

8865
8866 * keyboard.c (safe_run_hook_funcall): New function.
8867 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
8868 don't set the hook to nil, but remove the offending function instead.
8869 (Qcommand_hook_internal): Remove, unused.
8870 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
8871 Vcommand_hook_internal.
8872
8873 * eval.c (enum run_hooks_condition): Remove.
8874 (funcall_nil, funcall_not): New functions.
8875 (run_hook_with_args): Call each function through a `funcall' argument.

8879 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
8880
8881 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
8882
8883 * dispextern.h (string_buffer_position): Remove declaration.
8884
8885 * print.c (strout): Remove parameter `multibyte', unused since
8886 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
8887
8888 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
8889 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
8890 All callers changed.
8891
8892 * w32.c (_wsa_errlist): Use braces for struct initializers.
8893
8894 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
8895 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.

8933 2011-03-26 Eli Zaretskii <eliz@gnu.org>
8934
8935 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
8936 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
8937
8938 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
8939
8940 * w32.c (read_unc_volume): Use parameter `henum', instead of
8941 global variable `wget_enum_handle'.
8942
8943 * keymap.c (describe_vector): Remove parameters `indices' and
8944 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

9057 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
9058
9059 Fix more problems found by GCC 4.5.2's static checks.
9060
9061 * coding.c (encode_coding_raw_text): Avoid unnecessary test
9062 the first time through the loop, since we know p0 < p1 then.
9063 This also avoids a gcc -Wstrict-overflow warning.
9064
9065 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
9066 leading to a memory leak, possible in functions like
9067 load_charset_map_from_file that can allocate an unbounded number
9068 of objects (Bug#8318).
9069
9070 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
9071 that could (at least in theory) be that large.
9072
9073 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
9074 This is less likely to overflow, and avoids undefined behavior if
9075 overflow does occur. All callers changed. Use strtoul to scan
9076 for the unsigned long integer.
9077 (pint2hrstr): Simplify and tune code slightly.
9078 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

9086 This also avoids a warning with gcc -Wstrict-overflow.
9087
9088 * fileio.c (Fcopy_file): Report error if fchown or fchmod
9089 fail (Bug#8306).
9090
9091 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
9092
9093 * process.c (Fmake_network_process): Use socklen_t, not int,
9094 where POSIX says socklen_t is required in portable programs.
9095 This fixes a porting bug on hosts like 64-bit HP-UX, where
9096 socklen_t is wider than int (Bug#8277).
9097 (Fmake_network_process, server_accept_connection):
9098 (wait_reading_process_output, read_process_output):
9099 Likewise.
9100
9101 * process.c: Rename or move locals to avoid shadowing.

9108 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
9109 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
9110
9111 Make tparam.h and terminfo.c consistent.
9112 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
9113 Include tparam.h instead, since it declares them.
9114 * cm.h (PC): Remove extern decl; tparam.h now does this.
9115 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
9116 * terminfo.c: Include tparam.h, to check interfaces.
9117 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
9118 (tparam): Adjust signature to match interface in tparam.h;
9119 this removes some undefined behavior. Check that outstring and len
9120 are zero, which they always are with Emacs.
9121 * tparam.h (PC, BC, UP): New extern decls.
9122
9123 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
9124 (xftfont_open): Rename locals to avoid shadowing.
9125
9126 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
9127 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

9130 (get_adstyle_property, ftfont_pattern_entity):
9131 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
9132 Rename locals to avoid shadowing.
9133
9134 * xfont.c (xfont_list_family): Mark var as initialized.
9135
9136 * xml.c (make_dom): Now static.
9137
9138 * composite.c (composition_compute_stop_pos): Rename local to
9139 avoid shadowing.
9140 (composition_reseat_it): Remove unused locals.
9141 (find_automatic_composition, composition_adjust_point): Likewise.
9142 (composition_update_it): Mark var as initialized.
9143 (find_automatic_composition): Mark vars as initialized,
9144 with a FIXME (Bug#8290).
9145
9146 character.h: Rename locals to avoid shadowing.
9147 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
9148 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
9149 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
9150 (BUF_DEC_POS): Be more systematic about renaming local temporaries
9151 to avoid shadowing.
9152
9153 * textprop.c (property_change_between_p): Remove; unused.
9154
9155 * intervals.c (interval_start_pos): Now static.

9158
9159 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
9160 Rename locals to avoid shadowing.
9161
9162 * sound.c (wav_play, au_play, Fplay_sound_internal):
9163 Fix pointer signedness.
9164 (alsa_choose_format): Remove unused local var.
9165 (wav_play): Initialize a variable to 0, to prevent undefined
9166 behavior (Bug#8278).

9175 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
9176
9177 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
9178 This should get cleaned up, so that child_setup has the
9179 same signature on all platforms.
9180
9181 * callproc.c (call_process_cleanup): Now static.
9182 (relocate_fd): Rename locals to avoid shadowing.

9184 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
9185
9186 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
9187 not to be necessary, and produces flickering.
9188
9189 2011-03-20 Glenn Morris <rgm@gnu.org>
9190
9191 * config.in: Remove file.
9192

9245
9246 * deps.mk (unexalpha.o): Remove; unused.

9308 Move decls here, to check interfaces.
9309 * process.c (get_operating_system_release): Move decl to lisp.h.
9310 * xrdb.c (get_system_name): Likewise.
9311 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
9312 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
9313 some of which prompt warnings from gcc -Wbad-function-cast.

9315 (Ftranslate_region_internal, Fformat):
9316 Rename or remove local vars to avoid shadowing.

9323 ENABLE_CHECKING is not defined.
9324

9342 (GC_STRING_CHARS): Remove; not used.
9343 (Fmemory_limit): Cast sbrk's returned value to char *.
9344

9347
9348 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
9349
9350 Use functions, not macros, for up- and down-casing (Bug#8254).
9351 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
9352 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
9353 to use the following functions instead of these macros.
9354 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
9355 EMACS_INT, since callers assume the returned value fits in int.
9356 (upcase1): Likewise, for UPCASE_TABLE.
9357 (uppercasep, lowercasep, upcase): New static inline functions.
9358 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

9364 (regex_compile, re_search_2, re_match_2_internal):
9365 Remove unused local vars.
9366 (FREE_VAR): Rewrite so as not to use empty "else",
9367 which gcc can warn about.
9368 (regex_compile, re_match_2_internal): Mark locals as initialized.
9369 (RETALLOC_IF): Define only if needed.
9370 (WORDCHAR_P): Likewise. This one is never needed, but is used
9371 only in a comment talking about a compiler bug, so put inside
9372 the #if 0 of that comment.
9373 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
9374 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
9375 Remove; unused.

9386
9387 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
9388
9389 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
9390 All uses changed.
9391 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
9392 Rename locals to avoid shadowing.
9393 (Fvertical_motion): Mark locals as initialized.
9394
9395 * casefiddle.c (casify_object, casify_region): Now static.
9396 (casify_region): Mark local as initialized.
9397
9398 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
9399
9400 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
9401 New macros, so that the caller can use some names other than
9402 gcpro1, gcpro2, etc.
9403 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
9404 of the new macros.
9405 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
9406 argument, for consistency with GCPRO2_VAR, etc: it is now the
9407 prefix of the variable, not the variable itself. All uses
9408 changed.
9409 * dired.c (directory_files_internal, file_name_completion):
9410 Rename locals to avoid shadowing.
9411
9412 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
9413 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
9414 dired.c's scmp function, had undefined behavior.
9415 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
9416 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
9417 * buffer.h: ... to here, because these macros use current_buffer,
9418 and the new implementation with inline functions needs to have
9419 current_buffer in scope now, rather than later when the macros
9420 are used.
9421 (downcase, upcase1): New static inline functions.
9422 (DOWNCASE, UPCASE1): Reimplement using these functions.
9423 This avoids undefined behavior in expressions like
9424 DOWNCASE (x) == DOWNCASE (y), which previously suffered
9425 from race conditions in accessing the global variables
9426 case_temp1 and case_temp2.
9427 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
9428 * lisp.h (case_temp1, case_temp2): Remove their decls.
9429 * character.h (ASCII_CHAR_P): Move from here ...
9430 * lisp.h: ... to here, so that the inline functions mentioned
9431 above can use them.
9432
9433 * dired.c (directory_files_internal_unwind): Now static.
9434
9435 * fileio.c (file_name_as_directory, directory_file_name):
9436 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
9437 Now static.
9438 (file_name_as_directory): Use const pointers when appropriate.
9439 (Fexpand_file_name): Likewise. In particular, newdir might
9440 point at constant storage, so make it a const pointer.
9441 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
9442 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
9443 signedness issues.
9444 (Fset_file_times, Finsert_file_contents, auto_save_error):
9445 Rename locals to avoid shadowing.
9446
9447 * minibuf.c (choose_minibuf_frame_1): Now static.
9448 (Ftry_completion, Fall_completions): Rename or remove locals
9449 to avoid shadowing.
9450
9451 * marker.c (bytepos_to_charpos): Remove; unused.
9452
9453 * lisp.h (verify_bytepos, count_markers): New decls,
9454 so that gcc does not warn that these functions aren't declared.
9455
9456 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
9457 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
9458 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
9459 (copy_text): Remove unused local var.
9460
9461 * filelock.c (within_one_second): Now static.
9462 (lock_file_1): Rename local to avoid shadowing.
9463
9464 * buffer.c (fix_overlays_before): Mark locals as initialized.
9465 (fix_start_end_in_overlays): Likewise. This function should be
9466 simplified by using pointers-to-pointers, but that's a different
9467 matter.
9468 (switch_to_buffer_1): Now static.
9469 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
9470 (report_overlay_modification): Rename locals to avoid shadowing.
9471
9472 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
9473 Fix pointer signedness issue.
9474 (sys_subshell): Mark local as volatile if checking for lint,
9475 to suppress a gcc -Wclobbered warning that does not seem to be right.
9476 (MAXPATHLEN): Define only if needed.
9477
9478 * process.c (serial_open, serial_configure): Move decls from here ...
9479 * systty.h: ... to here, so that they can be checked.
9480
9481 * fns.c (get_random, seed_random): Move extern decls from here ...
9482 * lisp.h: ... to here, so that they can be checked.
9483
9484 * sysdep.c (reset_io): Now static.
9485 (wait_for_termination_signal): Remove; unused.
9486
9487 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
9488 (copy_keymap_item, append_key, push_text_char_description):
9489 Now static.
9490 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
9491 (DENSE_TABLE_SIZE): Remove; unused.
9492 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
9493 (describe_map_tree):
9494 Rename locals to avoid shadowing.
9495
9496 * keyboard.c: Declare functions static if they are not used elsewhere.
9497 (echo_char, echo_dash, cmd_error, top_level_2):
9498 (poll_for_input, handle_async_input): Now static.
9499 (read_char, kbd_buffer_get_event, make_lispy_position):
9500 (make_lispy_event, make_lispy_movement, apply_modifiers):
9501 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
9502 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
9503 (Fread_key_sequence_vector): Rename locals to avoid shadowing.

9507 * keyboard.h (make_ctrl_char): New decl.
9508 (mark_kboards): Move decl here ...
9509 * alloc.c (mark_kboards): ... from here.
9510
9511 * lisp.h (force_auto_save_soon): New decl.
9512
9513 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
9514 (DEFINE_DUMMY_FUNCTION): New macro.
9515 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
9516 Use it.
9517 (main): Add casts to avoid warnings
9518 if GCC considers string literals to be constants.
9519
9520 * lisp.h (fatal_error_signal): Add decl, since it's exported.
9521
9522 * dbusbind.c: Pointer signedness fixes.
9523 (xd_signature, xd_append_arg, xd_initialize):
9524 (Fdbus_call_method, Fdbus_call_method_asynchronously):
9525 (Fdbus_method_return_internal, Fdbus_method_error_internal):
9526 (Fdbus_send_signal, xd_read_message_1, Fdbus_register_service):
9527 (Fdbus_register_signal): Use SSDATA when the context wants char *.
9528
9529 * dbusbind.c (Fdbus_init_bus): Add cast to avoid warning
9530 if GCC considers string literals to be constants.

9566 * w32inevt.c (reinvoke_input_signal, lispy_function_keys):
9567 * w32menu.c (Qmenu_bar, QCtoggle, QCradio, Qoverriding_local_map)

9581 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
9582 These macros can no longer be used for assignment.
9583
9584 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9585 Assign struct members directly, instead of using BUF_BEGV etc.
9586 (record_buffer_markers, fetch_buffer_markers): New functions for
9587 recording and fetching special buffer markers.
