1 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
3 * ccl.c: Improve and simplify overflow checking (Bug#9196).
4 (ccl_driver): Do not generate an out-of-range pointer.
5 (Fccl_execute_on_string): Remove unnecessary check for
6 integer overflow, noted by Stefan Monnier in
7 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8 Remove a FIXME that didn't need fixing.
9 Simplify the newly-introduced buffer reallocation code.
11 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
13 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
17 Integer and memory overflow issues (Bug#9196).
19 * doc.c (get_doc_string): Rework so that
20 get_doc_string_buffer_size is the actual buffer size, rather than
21 being 1 less than the actual buffer size; this makes xpalloc more
24 * image.c (x_allocate_bitmap_record, cache_image):
25 * xselect.c (Fx_register_dnd_atom):
26 Simplify previous changes by using xpalloc.
28 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
29 since either will do and ptrdiff_t is convenient with xpalloc.
31 * charset.c (charset_table_size)
32 (struct charset_sort_data.priority): Now ptrdiff_t.
33 (charset_compare): Don't overflow if priorities differ greatly.
34 (Fsort_charsets): Don't assume list length fits in int.
35 Check for size-calculation overflow when allocating sort data.
36 (syms_of_charset): Allocate an initial charset table that is
37 just under 64 KiB, to avoid problems with glibc malloc and mmap.
39 * cmds.c (internal_self_insert): Check for size-calculation overflow.
41 * composite.h (struct composition.glyph_len): Now int, not unsigned.
42 The actual value is always <= INT_MAX, and leaving it unsigned made
43 overflow checking harder.
45 * dispextern.h (struct glyph_matrix.rows_allocated)
46 (struct face_cache.size): Now ptrdiff_t, for convenience in use
47 with xpalloc. The values are still always <= INT_MAX.
49 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
51 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
52 (SAFE_NALLOCA): New macro.
54 * region-cache.c (struct boundary.pos, find_cache_boundary)
55 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
56 (set_cache_region, invalidate_region_cache)
57 (revalidate_region_cache, know_region_cache, region_cache_forward)
58 (region_cache_backward, pp_cache):
59 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
60 so that ptrdiff_t * can be passed to xpalloc.
61 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
62 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
63 (pp_cache): Don't assume cache_len fits in int.
64 * region-cache.h: Adjust extern decls to match.
66 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
67 EMACS_INT, since either will do, for xpalloc.

72 * bidi.c (bidi_shelve_header_size): New constant.
73 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
74 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
76 * bidi.c (bidi_cache_shrink):
77 * buffer.c (overlays_at, overlays_in, record_overlay_string)
79 Don't update size of array until after memory allocation succeeds,
80 because xmalloc/xrealloc may not return.
81 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
82 now that we have proper integer overflow checking.
83 (record_overlay_string, overlay_strings): Catch overflows when
84 calculating size of overlay_str_buf.
86 * callproc.c (Fcall_process): Check for size overflow when
87 calculating size of args2.
88 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
89 Normally we prefer signed values, but sticking with ptrdiff_t would
90 require adding more-complicated checks.
92 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
93 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
94 Redo buffer-overflow calculations to avoid integer overflow.
95 Add a FIXME comment where memory seems to be over-allocated.
97 * character.c (Fstring): Check for size-calculation overflow.
99 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
100 unnecessary integer overflow. Check for size overflow.

119 (NEXT_ALMOST_PRIME_LIMIT): New constant.
121 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
122 (get_doc_string): Check for size calculation overflow.
123 Don't update size until allocation succeeds.
124 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
125 EMACS_INT, where ptrdiff_t will do.
126 (Fsubstitute_command_keys): Check for string overflow.
128 * editfns.c (set_time_zone_rule): Don't assume environment length
130 (message_length): Now ptrdiff_t, not int.
131 (Fmessage_box): Don't update size until allocation succeeds.
132 Don't assume message length fits in int.
133 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
135 * emacs.c (main): Do not reallocate argv, since there is a null at
136 the end that can be overwritten, and this way there's no need to
137 worry about size-calculation overflow.
138 (sort_args): Check for size-calculation overflow.
140 * eval.c (init_eval_once, grow_specpdl): Don't update size until
142 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.

145 (x_set_scroll_bar_width, x_figure_window_size):
146 Check for integer overflow.
147 (x_set_alpha): Do not assume XINT fits in int.
149 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
150 This is for the members text_lines, text_cols, total_lines, total_cols,
151 where the system imposes an 'int' limit.
153 * fringe.c (Fdefine_fringe_bitmap):
154 Don't update size until alloc works.
156 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
157 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
159 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
160 Check for size-calculation overflow.
161 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
162 do, as we prefer signed integers.
163 (id_to_widget.max_size, id_to_widget.used)
164 (xg_store_widget_in_map, xg_remove_widget_from_map)
165 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
166 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
167 Use and return ptrdiff_t, not int.
168 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
169 * gtkutil.h: Change prototypes to match the above.
171 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
172 are duplicate now that they've been promoted to lisp.h.
173 (x_allocate_bitmap_record, x_alloc_image_color)
174 (make_image_cache, cache_image, xpm_load):
175 Don't update size until alloc is done.
176 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
178 Check for size calculation overflow.

215 * search.c (Freplace_match): Check for size calculation overflow.
216 (Fset_match_data): Don't assume list lengths fit in 'int'.
218 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
219 for command line length. Do not attempt to address one before the
220 beginning of an array, as that's not portable.

252 memory exhaustion (the usual treatment), rather than aborting.
254 * xfns.c (x_encode_text, x_set_name_internal)
255 (Fx_change_window_property): Use ptrdiff_t, not int, to count
256 sizes, since they can exceed INT_MAX in size. Check for size
257 calculation overflow.
259 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
260 (xg_select): Check for size calculation overflow.
261 Don't update size until alloc done.
263 * xrdb.c (get_environ_db): Don't assume path length fits in int,
264 as sprintf is limited to int lengths.
266 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
267 (X_LONG_MIN): New macros.
268 Use them to make the following changes clearer.
269 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
270 This change doesn't affect the value now, but it may help remind
271 future maintainers not to raise the value too much later.
272 (SELECTION_QUANTUM): Remove, replacing with ...
273 (selection_quantum): ... new function, which avoids overflow.
275 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
276 assumption that selection length fits in 'int'.
277 (x_reply_selection_request, x_handle_selection_request)
278 (x_get_window_property, receive_incremental_selection)
279 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)

293 Don't store size until memory allocation succeeds.
294 (x_get_window_property): Plug memory leak on memory exhaustion.
295 Don't double-block input; malloc is safe here. Don't assume 2**34
296 - 4 fits in unsigned long. Add an xassert to check
297 XGetWindowProperty overflow. Be more careful about overflow
298 calculations, and distinguish size from memory overflow better.
299 (receive_incremental_selection): When tracing, don't assume
300 unsigned int is less than INT_MAX.
301 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
302 harmful) conversions of unsigned short to int.
303 (lisp_data_to_selection_data): Don't assume that integers
304 in the range -65535 through -1 fit in an X unsigned short.
305 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
306 result parameters unless successful. Rely on cons_to_unsigned
307 to report problems with elements; the old code wasn't right anyway.
308 (x_check_property_data): Check for int overflow; we cannot use
309 a wider type due to X limits.
310 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

341 * image.c (xpm_get_color_table_h):
342 * lisp.h (hash_lookup, hash_put):
343 * minibuf.c (Ftest_completion):
344 Use ptrdiff_t for hash table indexes, not int (which is too
345 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
346 32-bit --with-wide-int hosts).
348 * charset.c (Fdefine_charset_internal): Check for integer overflow.
349 Add a FIXME comment about memory leaks.
350 (syms_of_charset): Don't assume xmalloc returns.

356 Use sanitize_char_width to avoid undefined and/or bad behavior
357 with outlandish widths.
358 * character.h (sanitize_tab_width): Renamed from sanitize_width,
359 now that we have two such functions. All uses changed.
360 (sanitize_char_width): New inline function.

378 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
379 (x_send_scroll_bar_event): Likewise. Check that the size does not
380 exceed limits imposed by XClientMessageEvent, as well as the usual
381 ptrdiff_t and size_t limits.
383 * keyboard.c: Overflow, signedness and related fixes.
384 (make_lispy_movement): Use same integer type in forward decl
385 that is used in the definition.
386 (read_key_sequence, keyremap_step):
387 Change bufsize argument back to int, undoing my 2011-03-30 change.
388 We prefer signed types, and int is wide enough here.
389 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
390 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
391 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
392 length, not size_t. Use ptrdiff_t for index, not int.
393 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
394 possibility of integer overflow.

422 Prefer int to unsigned where either will do.
423 (tiff_handler): New function, combining the cores of the
424 old tiff_error_handler and tiff_warning_handler. This
425 function is rewritten to use vsnprintf and thereby avoid
426 stack buffer overflows. It uses only the features of vsnprintf
427 that are common to both POSIX and native Microsoft.
428 (tiff_error_handler, tiff_warning_handler): Use it.
429 (tiff_load, gif_load, imagemagick_load_image):
430 Don't assume :index value fits in 'int'.
431 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

433 the integer types that MagickCropImage accepts. Don't assume
434 Vimagemagick_render_type has a nonnegative value. Don't assume
435 size_t fits in 'long'.
436 (gs_load): Use printmax_t to print the widest integers possible.

447 the display spec is of the form `(space ...)'.
448 (handle_display_spec): Return the value returned by
449 handle_single_display_spec, not just 1 or zero.
450 (handle_single_display_spec): If the display spec is of the form
451 `(space ...)', and specifies display in the text area, return 2
453 (try_cursor_movement): Check for the need to scroll more
454 accurately, and prefer exact match for point under bidi. Don't
455 advance `row' beyond the last row of the window.
457 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
458 into disp_prop; all users changed.
460 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
461 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
462 for the text covered by the display property.
464 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
466 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

475 represents a newline and point is on that newline. Fixes cursor
476 positioning on the newline at EOL of R2L text within L2R
477 paragraph, and vice versa.
478 (try_cursor_movement): Check continued rows, in addition to
479 continuation rows. Fixes unwarranted scroll when point enters a
480 continued line of R2L text within an L2R paragraph, or vice versa.
481 (cursor_row_p): Consider the case of point being equal to
482 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
483 from the end of a short line to the beginning of a continued line
484 of R2L text within L2R paragraph.
485 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
488 * bidi.c (bidi_check_type): Use xassert.
489 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
492 2011-08-23 Eli Zaretskii <eliz@gnu.org>
494 * bidi.c (bidi_get_type): Abort if we get zero as the bidi type of

501 2011-08-22 Kenichi Handa <handa@m17n.org>
503 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
504 extra slot even if the purpose is char-code-property-table.
506 2011-08-23 Eli Zaretskii <eliz@gnu.org>
508 * xdisp.c (redisplay_window): When computing centering_position,
509 account for the height of the header line. (Bug#8874)
511 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
512 instead of CHAR_TO_BYTE. Fixes a crash when a completion
513 candidate is selected by the mouse, and that candidate has a
514 composed character under the mouse.
516 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
517 coordinates reported by pos-visible-in-window-p for a composed
518 character in column zero.
520 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
522 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
524 2011-08-22 Eli Zaretskii <eliz@gnu.org>
526 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
527 consider it a hit if to_charpos is anywhere in the range of the
528 composed buffer positions.
530 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
532 * image.c (gif_load): Don't assume that each subimage has the same
533 dimensions as the base image. Handle disposal method that is
534 "undefined" by the gif spec (Bug#9335).
536 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
538 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
539 (Fcondition_case): Document `debug' symbol in error handler.
541 2011-08-19 Eli Zaretskii <eliz@gnu.org>
543 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
544 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
545 from an Org mode buffer to a Speedbar frame.
547 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
548 a composition, take its buffer position from IT->cmp_it.charpos.
549 Fixes cursor positioning at the beginning of a line that begins
550 with a composed character.
552 2011-08-18 Eli Zaretskii <eliz@gnu.org>
554 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
555 character bidirectional type, use STRONG_L instead. Fixes crashes
556 in a buffer produced by `describe-categories'.
558 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
559 members before the level stack, so they would be saved and
560 restored when copying iterator state. Fixes incorrect reordering
561 around TABs covered by display properties.
563 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
565 * process.c (Fnetwork_interface_list): Correctly determine buffer
568 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
570 * eval.c (internal_condition_case, internal_condition_case_1)
571 (internal_condition_case_2, internal_condition_case_n):
572 Remove unnecessary aborts (Bug#9081).
574 2011-08-17 Eli Zaretskii <eliz@gnu.org>
576 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
577 has no `load' handler, try opening the file locally. (Bug#9311)
579 2011-08-16 Ken Brown <kbrown@cornell.edu>
581 * gmalloc.c: Expand comment.
583 2011-08-16 Eli Zaretskii <eliz@gnu.org>
585 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
586 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
588 2011-08-16 Ken Brown <kbrown@cornell.edu>
590 Fix memory allocation problems in Cygwin build (Bug#9273).
592 * unexcw.c ( __malloc_initialized): Declare external variable.
593 (fixup_executable): Force the dumped emacs to reinitialize malloc.

599 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
601 [CYGWIN] (special_realloc): New function.
602 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
603 requests to realloc storage in the static heap.

623 * chartab.c: Improve commentary for the uniprop_table API.
625 * bidi.c (bidi_paragraph_init): Support zero value of
626 bidi_ignore_explicit_marks_for_paragraph_level.
627 (bidi_initialize): Use uniprop_table instead of including
628 biditype.h and bidimirror.h.
630 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
631 coordinates of the iterator when restoring from ppos_it.
634 2011-08-14 Kenichi Handa <handa@m17n.org>
636 * process.c (create_process): Call setup_process_coding_systems
637 after the pid of the process is set to -1 (Bug#8162).
639 2011-08-14 Eli Zaretskii <eliz@gnu.org>
641 * xdisp.c (move_it_in_display_line_to): Don't invoke
642 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
643 ppos_it. Fixes vertical cursor motion when line beginning is
644 covered by an image. (Bug#9296)
646 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
648 * nsterm.h (ns_run_ascript): Declare.
649 (NSAPP_DATA2_RUNASSCRIPT): Define.
651 * nsfns.m (as_script, as_result, as_status): New static variables.
652 (ns_run_ascript): New function.
653 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
654 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
655 the event loop. Get status from as_status (Bug#7276).
657 * nsterm.m (sendEvent): If event is NSApplicationDefined and
658 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
659 the event loop (Bug#7276).
661 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
663 * gnutls.c (QCgnutls_bootprop_priority)
664 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
665 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
666 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
667 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
668 (QCgnutls_bootprop_verify_hostname_error)
669 (QCgnutls_bootprop_callbacks_verify): Rename from
670 Qgnutls_bootprop_..., all uses changed.

682 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
684 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
685 (Fnetwork_interface_list): Allocate in increments of bytes instead
686 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
687 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
689 (struct ifflag_def): notrailers is smart on OSX.
690 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
691 Get hardware address with getifaddrs if available.
693 2011-08-12 Eli Zaretskii <eliz@gnu.org>
695 * xdisp.c (iterate_out_of_display_property): xassert that
696 IT->position is set to within IT->object's boundaries. Break from
697 the loop as soon as EOB is reached; avoids infloops in redisplay
698 when IT->position is set up wrongly due to some bug.
699 Set IT->current to match the bidi iterator unconditionally.
700 (push_display_prop): Allow GET_FROM_STRING as IT->method on
701 entry. Force push_it to save on the stack the current
702 buffer/string position, to be restored by pop_it. Fix flags in
703 the iterator structure wrt the object coming from a display
704 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
705 properties. (Bug#9284)
707 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
709 * fontset.c (fontset_get_font_group): Add proper type checks.

719 2011-08-08 Eli Zaretskii <eliz@gnu.org>
721 * xdisp.c (forward_to_next_line_start): Allow to use the
722 no-display-properties-and-no-overlays under bidi display.
723 Set disp_pos in the bidi iterator to avoid searches for display
724 properties and overlays.
726 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
728 * editfns.c (Fset_time_zone_rule): Document relationship with the
731 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
732 the font entity extracted from the cache (Bug#8109).
734 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
736 * composite.c (autocmp_chars): Don't reset point. That is done by
737 restore_point_unwind (Bug#5984).
739 2011-08-07 Juri Linkov <juri@jurta.org>
741 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
742 to show the arg `TIME' instead of `TIMEVAL'.
744 2011-08-06 Eli Zaretskii <eliz@gnu.org>
746 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
747 display property strides EOL and includes a newline, as in
748 longlines-mode. (Bug#9254)
749 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
750 word-wrap under bidirectional display. (Bug#9224)
752 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
753 is non-zero, even if the data buffer is NULL. Fixes a crash in
754 vertical-motion with longlines-mode. (Bug#9254)
756 2011-08-05 Eli Zaretskii <eliz@gnu.org>
758 * bidi.c <bidi_cache_total_alloc>: Now static.
759 (bidi_initialize): Initialize bidi_cache_total_alloc.
761 * xdisp.c (display_line): Release buffer allocated for shelved bidi
764 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
765 amount allocated this far in `bidi_cache_total_alloc'.
766 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
767 non-zero, only free the data buffer without restoring the cache
768 contents. All callers changed.
770 * dispextern.h (bidi_unshelve_cache): Update prototype.
772 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
773 (move_it_in_display_line, move_it_to)
774 (move_it_vertically_backward, move_it_by_lines): Replace the call
775 to xfree to an equivalent call to bidi_unshelve_cache.
776 (move_it_in_display_line_to): Fix logic of returning
777 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
779 2011-08-05 Eli Zaretskii <eliz@gnu.org>
781 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
782 came from a string character with a `cursor' property. (Bug#9229)
784 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
786 * Makefile.in (LIB_PTHREAD): New variable.
787 (LIBES): Add LIB_PTHREAD (Bug#9216).
789 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
790 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
792 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
794 * regex.c (re_iswctype): Remove some redundant boolean

818 * xdisp.c (compute_display_string_pos): Remove unused local.
820 2011-08-02 Eli Zaretskii <eliz@gnu.org>
822 Fix slow cursor motion and scrolling in large buffers with
823 selective display, like Org Mode buffers. (Bug#9218)
825 * dispextern.h (struct bidi_it): New member disp_prop_p.
827 * xdisp.c: Remove one-slot cache of display string positions.
828 (compute_display_string_pos): Accept an additional argument
829 DISP_PROP_P; callers changed. Scan at most 5K characters forward
830 for a display string or property. If found, set DISP_PROP_P
833 * bidi.c (bidi_fetch_char): Accept an additional argument
834 DISP_PROP_P, and pass it to compute_display_string_pos.
835 Only handle text covered by a display string if DISP_PROP_P is returned
836 non-zero. All callers of bidi_fetch_char changed.
838 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
840 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
842 2010-12-03 Don March <don@ohspite.net>
844 * keymap.c (Fdefine_key): Fix non-prefix key error message when
845 last character M-[char] is translated to ESC [char] (bug#7541).
847 2011-08-02 Kenichi Handa <handa@m17n.org>
849 * lisp.h (uniprop_table): Extern it.

856 BIDI_IT_PREV, and store into it the state of the bidi iterator had
858 (reseat_at_next_visible_line_start): Use the bidi iterator state
859 returned by forward_to_next_line_start to restore the state of
860 it->bidi_it after backing up to previous newline. (Bug#9212)
862 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
864 * regex.c (re_comp): Protoize.
865 (re_exec): Fix return type.

870 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
871 This is needed if max-image-size is a floating-point number.
873 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
875 * print.c (print_object): Print empty symbol as ##.
877 * lread.c (read1): Read ## as empty symbol.
879 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
881 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
882 setting frame foreground color (Bug#9175).
883 (x_set_background_color): Likewise.
885 * nsmenu.m (-setText): Size tooltip dimensions precisely to
887 (EmacsTooltip -init): Remove bezels and add shadows to
890 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
891 or scroll bar (Bug#8470).
893 * nsfont.m (nsfont_open): Remove assignment to voffset and
894 unnecessary vars hshink, expand, hd, full_height, min_height.
895 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
897 * nsterm.h (nsfont_info): Remove voffset field.
899 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
901 Implement strike-through and overline on NextStep (Bug#8863).
903 * nsfont.m (nsfont_open): Use underline position provided by font,
904 instead of hard-coded value of 2.
905 (nsfont_draw): Call ns_draw_text_decoration instead.

917 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
920 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
922 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
923 Without this fix, if a signal arrives just after memory fills up,
924 'malloc' might be invoked reentrantly.
926 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
927 In other words, assume that every image size is allowed, on non-X
928 hosts. This assumption is probably wrong, but it lets Emacs compile.
930 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
932 * regex.c (re_iswctype): Convert return values to boolean.
934 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
936 * xdisp.c (compute_display_string_pos): Don't use cached display
937 string position if the buffer had its restriction changed.
940 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>

948 * bidi.c: Integer size and overflow fixes.
949 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
950 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
951 (bidi_cache_find_level_change, bidi_cache_ensure_space)
952 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
953 (bidi_find_other_level_edge):
954 Use ptrdiff_t instead of EMACS_INT where either will do.
955 This works better on 32-bit hosts configured --with-wide-int.
956 (bidi_cache_ensure_space): Check for size-calculation overflow.
957 Use % rather than repeated addition, for better worst-case speed.
958 Don't set bidi_cache_size until after xrealloc returns, because it
960 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
961 (bidi_cache_ensure_space): Also check that the bidi cache size
962 does not exceed that of the largest Lisp string or buffer. See Eli
963 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
965 * alloc.c (__malloc_size_t): Remove.
966 All uses replaced by size_t. See Andreas Schwab's note
967 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
969 * image.c: Improve checking for integer overflow.
970 (check_image_size): Assume that f is nonnull, since
971 it is always nonnull in practice. This is one less thing to
972 worry about when checking for integer overflow later.
973 (x_check_image_size): New function, which checks for integer
974 overflow issues inside X.
975 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
976 This removes the need for a memory_full check.
977 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
978 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
979 (xbm_read_bitmap_data): Change locals back to 'int', since
980 their values must fit in 'int'.
981 (xpm_load_image, png_load, tiff_load):
982 Invoke x_create_x_image_and_pixmap earlier,
983 to avoid much needless work if the image is too large.
984 (tiff_load): Treat overly large images as if
985 x_create_x_image_and_pixmap failed, not as malloc failures.
986 (gs_load): Use x_check_image_size.
988 * gtkutil.c: Omit integer casts.
989 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
990 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
992 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
994 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
995 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
996 would wrongly return t on a 64-bit host.
998 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
999 The plain *_OVERFLOW macros run afoul of GCC bug 49705
1000 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
1001 and therefore cause GCC to emit a bogus diagnostic in some cases.
1003 * image.c: Integer signedness and overflow and related fixes.
1004 This is not an exhaustive set of fixes, but it's time to
1005 record what I've got.
1006 (lookup_pixel_color, check_image_size): Remove redundant decls.
1007 (check_image_size): Don't assume that arbitrary EMACS_INT values
1008 fit in 'int', or that arbitrary 'double' values fit in 'int'.
1009 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
1010 (tiff_load, imagemagick_load_image):
1011 Check for overflow in size calculations.
1012 (x_create_x_image_and_pixmap): Remove unnecessary test for
1013 xmalloc returning NULL; that can't happen.
1014 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
1015 (xpm_color_bucket): Use better integer hashing function.
1016 (xpm_cache_color): Don't possibly over-allocate memory.
1017 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
1018 (gif_memory_source):
1019 Use ptrdiff_t, not int or size_t, to record sizes.
1020 (png_load): Don't assume values greater than 2**31 fit in 'int'.
1021 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
1022 either works, as we prefer signed integers.
1023 (tiff_read_from_memory, tiff_write_from_memory):
1024 Return tsize_t, not size_t, since that's what the TIFF API wants.
1025 (tiff_read_from_memory): Don't fail simply because the read would
1026 go past EOF; instead, return a short read.
1027 (tiff_load): Omit no-longer-needed casts.
1028 (Fimagemagick_types): Don't assume size fits into 'int'.
1030 Improve hashing quality when configured --with-wide-int.
1031 * fns.c (hash_string): New function, taken from sxhash_string.
1032 Do not discard information about ASCII character case; this
1033 discarding is no longer needed.
1034 (sxhash-string): Use it. Change sig to match it. Caller changed.
1035 * lisp.h: Declare it.
1036 * lread.c (hash_string): Remove, since we now use fns.c's version.
1037 The fns.c version returns a wider integer if --with-wide-int is
1038 specified, so this should help the quality of the hashing a bit.
1040 * emacs.c: Integer overflow minor fix.
1041 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
1042 Define only if GNU_LINUX.
1043 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
1045 * dispnew.c: Integer signedness and overflow fixes.
1046 Remove unnecessary forward decls, that were a maintenance hassle.
1047 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
1049 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
1050 (scrolling_window): Use ptrdiff_t, not int, for byte count.
1051 (prepare_desired_row, line_draw_cost):
1052 Use int, not unsigned, where either works.
1053 (save_current_matrix, restore_current_matrix):
1054 Use ptrdiff_t, not size_t, where either works.
1055 (init_display): Check for overflow more accurately, and without
1056 relying on undefined behavior.
1058 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
1059 Remove, replacing with the new symbols in lisp.h. All uses changed.
1060 * fileio.c (make_temp_name):
1061 * filelock.c (lock_file_1, lock_file):
1062 * xdisp.c (message_dolog):
1063 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
1064 Use pMd etc. instead.
1065 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
1066 replacing the pWIDE etc. symbols removed from editfns.c.
1068 * keyboard.h (num_input_events): Now uintmax_t.
1069 This is (very slightly) less likely to mess up due to wraparound.
1072 * buffer.c: Integer signedness fixes.
1073 (alloc_buffer_text, enlarge_buffer_text):
1074 Use ptrdiff_t rather than size_t when either will do, as we prefer
1077 * alloc.c: Integer signedness and overflow fixes.
1078 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
1079 (__malloc_size_t): Default to size_t, not to int.
1080 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
1081 (Fgarbage_collect, mark_object_loop_halt, mark_object):
1082 Prefer ptrdiff_t to size_t when either would do, as we prefer
1084 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
1085 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
1086 Now const. Initialize with values that are in range even if char
1088 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
1089 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
1090 These functions do the right thing with sizes > 2**32.
1091 (check_depth): Now ptrdiff_t, not int.
1092 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
1093 Adjust to new way of storing sizes. Check for size overflow bugs
1095 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
1096 slightly wrong anyway, as it missed one instance of
1097 XMALLOC_OVERRUN_CHECK_OVERHEAD.
1098 (refill_memory_reserve): Omit needless cast to size_t.
1099 (mark_object_loop_halt): Mark as externally visible.
1101 * xselect.c: Integer signedness and overflow fixes.
1102 (Fx_register_dnd_atom, x_handle_dnd_message):
1103 Use ptrdiff_t, not size_t, since we prefer signed.
1104 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
1105 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
1106 x_dnd_atoms_size and x_dnd_atoms_length.
1108 * doprnt.c: Prefer signed to unsigned when either works.
1110 * doprnt.c (doprnt):
1112 * xdisp.c (vmessage):
1113 Use ptrdiff_t, not size_t, when using or implementing doprnt,
1114 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
1115 prefer signed arithmetic to avoid comparison confusion.
1116 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
1117 but is a bit tricky.
1119 Assume freestanding C89 headers, string.h, stdlib.h.
1120 * data.c, doprnt.c, floatfns.c, print.c:
1121 Include float.h unconditionally.
1122 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
1123 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
1124 * regex.c: Likewise for stddef.h, string.h.
1125 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
1126 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
1127 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
1128 (STDC_HEADERS): Remove obsolete defines.
1129 * sysdep.c: Include limits.h unconditionally.
1131 Assume support for memcmp, memcpy, memmove, memset.
1132 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
1133 * regex.c (memcmp, memcpy):
1134 Remove; we assume C89 now.
1136 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
1137 (__malloc_safe_bcopy): Remove; no longer needed.
1139 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
1140 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
1141 well either way, and we prefer signed to unsigned.
1143 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
1145 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
1146 closes the connection while we're reading (bug#9182).
1148 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
1150 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
1151 are specified (Bug#9168).
1153 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
1155 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
1156 Found by GCC static checking and --with-wide-int on a 32-bit host.
1158 2011-07-25 Eli Zaretskii <eliz@gnu.org>
1160 * xdisp.c (compute_display_string_pos): Fix logic of caching
1161 previous display string position. Initialize cached_prev_pos to
1162 -1. Fixes slow-down at the beginning of a buffer.
1164 2011-07-24 Eli Zaretskii <eliz@gnu.org>
1166 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
1167 for attrs[LFACE_FONTSET_INDEX].
1169 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
1171 * xml.c (parse_region): Remove unused local
1172 that was recently introduced.
1174 2011-07-23 Eli Zaretskii <eliz@gnu.org>
1176 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
1177 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
1179 * xdisp.c (move_it_in_display_line_to): Record the best matching
1180 position for TO_CHARPOS while scanning the line, and restore it on
1181 exit if none of the characters scanned was an exact match.
1182 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
1183 when exact match is impossible due to invisible text, and the
1184 lines are truncated.
1186 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
1188 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
1191 2011-07-22 Eli Zaretskii <eliz@gnu.org>
1193 Fix a significant slow-down of cursor motion with C-n, C-p,
1194 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
1195 auto-repeat under bidi redisplay in fontified buffers.
1196 * xdisp.c (compute_stop_pos_backwards): New function.
1197 (next_element_from_buffer): Call compute_stop_pos_backwards to
1198 find a suitable prev_stop when we find ourselves before
1200 (reseat): Don't look for prev_stop, as that could mean a very long
1202 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
1203 <cached_disp_overlay_modiff>: Cache for last found display string
1205 (compute_display_string_pos): Return the cached position if asked
1206 about the same buffer in the same area of character positions, and
1207 the buffer wasn't changed since the time the display string
1208 position was cached.
1210 2011-07-22 Eli Zaretskii <eliz@gnu.org>
1212 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
1213 is an integer, which is important for empty lines. (Bug#9149)
1215 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
1217 * frame.c (Fmodify_frame_parameters): In tty case, update the
1218 default face if necessary (Bug#4238).
1220 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
1222 * editfns.c (Fstring_to_char): No need to explain what a character
1223 is in the docstring (Bug#6576).
1225 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
1227 * xml.c (parse_region): Make sure we always return a tree.
1229 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
1231 * xml.c (parse_region): If a document contains only comments,
1234 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
1236 * xml.c (make_dom): Return comments, too.
1238 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
1241 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
1242 and the surrounding thread.
1243 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
1244 rather than fgets, and retry after EINTR. Otherwise, 'emacs
1245 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
1247 * s/openbsd.h (BROKEN_SIGIO): Define.
1248 * unexelf.c (unexec) [__OpenBSD__]:
1249 Don't update the .mdebug section of the Alpha COFF symbol table.
1251 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
1253 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
1256 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
1258 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
1259 This fixes some race conditions on the permissions of any newly
1262 * alloc.c (valid_pointer_p): Use pipe, not open.
1263 This fixes some permissions issues when debugging.
1265 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
1266 If fchown fails to set both uid and gid, try to set just gid,
1267 as that is sometimes allowed. Adjust the file's mode to eliminate
1268 setuid or setgid bits that are inappropriate if fchown fails.
1270 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
1272 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
1273 to compare Lisp_Objects.
1274 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
1275 global_gnutls_log_level, don't mistake it for a Lisp_Object.
1276 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
1278 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
1280 * lread.c (read_integer): Unread even EOF character.
1281 (read1): Likewise. Properly record start position of symbol.
1283 * lread.c (read1): Read `#:' as empty uninterned symbol if no
1284 symbol character follows.
1286 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
1288 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
1289 This works around a problem with the previous change to Fcopy_file.
1290 Recent glibc declares fchown with __attribute__((warn_unused_result)),
1291 and without this change, GCC might complain about discarding
1292 fchown's return value.
1294 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
1296 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
1298 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
1300 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
1302 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
1304 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
1305 it's used from the C level.
1307 * process.c: Use the same condition for POLL_FOR_INPUT in both
1308 keyboard.c and process.c (bug#1858).
1310 2011-07-09 Lawrence Mitchell <wence@gmx.li>
1312 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
1313 (Fgnutls_boot): Use it.
1315 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
1317 * doc.c (Fsubstitute_command_keys): Revert last change.
1319 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
1321 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
1322 quotes the next character, and doesn't affect other longer
1323 sequences (bug#8935).
1325 * lread.c (syms_of_lread): Clarify that is isn't only
1326 `eval-buffer' and `eval-defun' that's affected by
1327 `lexical-binding' (bug#8460).
1329 2011-07-15 Eli Zaretskii <eliz@gnu.org>
1331 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
1332 bidi redisplay when a line includes both an image and is
1335 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
1337 Fix minor problems found by static checking.
1338 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
1339 (elsz): Now a signed constant, not a size_t var. We prefer signed
1340 types to unsigned, to avoid integer comparison confusion. Without
1341 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
1342 "cannot optimize loop, the loop counter may overflow", a symptom
1344 * indent.c (Fvertical_motion): Mark locals as initialized.
1345 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
1347 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
1349 * search.c (Fre_search_backward): Mention `case-fold-search' in
1350 all the re_search_* functions (bug#8138).
1352 * keyboard.c (Fopen_dribble_file): Document when the file is
1355 2011-07-14 Eli Zaretskii <eliz@gnu.org>
1357 * bidi.c (bidi_dump_cached_states): Fix format of displaying
1360 Support bidi reordering of display and overlay strings.
1361 * xdisp.c (compute_display_string_pos)
1362 (compute_display_string_end): Accept additional argument STRING.
1363 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
1364 (reseat_to_string): Initialize bidi_it->string.s and
1365 bidi_it->string.schars.
1366 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
1367 NULL (avoids a crash in bidi_paragraph_init).
1368 Initialize itb.string.lstring.
1369 (init_iterator): Call bidi_init_it only of a valid
1370 buffer position was specified. Initialize paragraph_embedding to
1372 (reseat_to_string): Initialize the bidi iterator.
1373 (display_string): If we need to ignore text properties of
1374 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
1375 original value of -1 will not work with bidi.)
1376 (compute_display_string_pos): First arg is now struct
1377 `text_pos *'; all callers changed. Support display properties on
1379 (compute_display_string_end): Support display properties on Lisp
1381 (init_iterator, reseat_1, reseat_to_string): Initialize the
1382 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
1383 when iterating on a string not from display properties).
1384 (compute_display_string_pos, compute_display_string_end):
1385 Fix calculation of the object to scan. Fixes an error when using
1387 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
1388 base_level_stop; instead, set base_level_stop to BEGV.
1389 Fixes crashes in vertical-motion.
1390 (next_element_from_buffer): Improve commentary for when
1391 the iterator is before prev_stop.
1392 (init_iterator): Initialize bidi_p from the default value of
1393 bidi-display-reordering, not from buffer-local value. Use the
1394 buffer-local value only if initializing for buffer iteration.
1395 (handle_invisible_prop): Support invisible properties on strings
1396 that are being bidi-reordered.
1397 (set_iterator_to_next): Support bidi reordering of C strings and
1399 (next_element_from_string): Support bidi reordering of Lisp
1401 (handle_stop_backwards): Support Lisp strings as well.
1402 (display_string): Support display of R2L glyph rows.
1403 Use IT_STRING_CHARPOS when displaying from a Lisp string.
1404 (init_iterator): Don't initialize it->bidi_p for strings
1406 (reseat_to_string): Initialize it->bidi_p for strings here.
1407 (next_element_from_string, next_element_from_c_string)
1408 (next_element_from_buffer): Add xassert's for correspondence
1409 between IT's object being iterated and it->bidi_it.string
1411 (face_before_or_after_it_pos): Support bidi iteration.
1412 (next_element_from_c_string): Handle the case of the first string
1413 character that is not the first one in the visual order.
1414 (get_visually_first_element): New function, refactored from common
1415 parts of next_element_from_buffer, next_element_from_string, and
1416 next_element_from_c_string.
1417 (tool_bar_lines_needed, redisplay_tool_bar)
1418 (display_menu_bar): Force left-to-right direction. Add a FIXME
1419 comment for making that be controlled by a user option.
1420 (push_it, pop_it): Save and restore the state of the
1421 bidi iterator. Save and restore the bidi_p flag.
1422 (pop_it): Iterate out of display property for string iteration as
1424 (iterate_out_of_display_property): Support iteration over strings.
1425 (handle_single_display_spec): Set up it->bidi_it for iteration
1426 over a display string, and call bidi_init_it.
1427 (handle_single_display_spec, next_overlay_string)
1428 (get_overlay_strings_1, push_display_prop): Set up the bidi
1429 iterator for displaying display or overlay strings.
1430 (forward_to_next_line_start): Don't use the shortcut if
1432 (back_to_previous_visible_line_start): If handle_display_prop
1433 pushed the iterator stack, restore the internal state of the bidi
1434 iterator by calling bidi_pop_it same number of times.
1435 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
1436 and we are bidi-iterating, don't decrement the iterator position;
1437 instead, set the first_elt flag in the bidi iterator, to produce
1439 (reseat_1): Remove redundant setting of string_from_display_prop_p.
1440 (push_display_prop): xassert that we are iterating a buffer.
1441 (push_it, pop_it): Save and restore paragraph_embedding member.
1442 (handle_single_display_spec, next_overlay_string)
1443 (get_overlay_strings_1, reseat_1, reseat_to_string)
1444 (push_display_prop): Set up the `unibyte' member of bidi_it.string
1445 correctly. Don't assume unibyte strings are not bidi-reordered.
1446 (compute_display_string_pos)
1447 (compute_display_string_end): Fix handling the case of C string.
1448 (push_it, pop_it): Save and restore from_disp_prop_p.

1905 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
1907 Random fixes. E.g., (random) never returned negative values.
1908 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
1909 subseconds part to the entropy, as that's a bit more random.
1910 Prefer signed to unsigned, since the signedness doesn't matter and
1911 in general we prefer signed. When given a limit, use a
1912 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
1913 latter isn't right if USE_2_TAGS_FOR_INTS.
1914 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
1915 not 0..VALMASK. Don't discard "excess" bits that random () returns.
1917 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1919 * textprop.c (text_property_stickiness):

1925 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
1927 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
1928 This is more efficient than Ffile_directory_p and avoids a minor race.
1930 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
1932 * buffer.c (Foverlay_put): Say what the return value is
1935 * fileio.c (barf_or_query_if_file_exists): Check first if the file
1936 is a directory before asking whether to use the file name
1938 (barf_or_query_if_file_exists): Make the "File is a directory"
1939 error be more correct.
1941 * fns.c (Frequire): Remove the mention of the .gz files, since
1942 that's installation-specific, but keep the mention of
1943 `get-load-suffixes'.
1945 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
1947 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

1954 Qgnutls_bootprop_verify_hostname_error, an error for
1955 Qgnutls_bootprop_verify_error (which is no longer used).
1957 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
1958 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
1959 Also (re)move comments that are misplaced or no longer relevant.
1961 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
1963 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

1992 (Frequire): Mention get-load-suffixes.
1994 2011-07-02 Martin Rudalics <rudalics@gmx.at>
1996 * window.h (window): Remove clone_number slot.

2055 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
2058 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
2060 * eval.c (struct backtrace): Simplify and port the data structure.
2061 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
2062 signed bit field, as this assumption is not portable and it makes
2063 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
2064 "char debug_on_exit : 1" as this is not portable either; instead,
2065 use the portable "unsigned int debug_on_exit : 1". Remove unused
2066 member evalargs. Remove obsolete comments about cc bombing out.
2068 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

2230 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
2232 Integer and buffer overflow fixes (Bug#8873).
2234 * print.c (printchar, strout): Check for string overflow.
2235 (PRINTPREPARE, printchar, strout):
2236 Don't set size unless allocation succeeds.
2238 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
2239 for sizes. Check for string overflow more accurately.

2257 read-circle numbers.
2258 (read_escape): Avoid int overflow.
2259 (Fload, openp, read_buffer_size, read1)
2260 (substitute_object_recurse, read_vector, read_list, map_obarray):

2281 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
2283 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
2284 The following patches are for when GLYPH_DEBUG && !XASSERT.
2285 * dispextern.h (trace_redisplay_p, dump_glyph_string):
2286 * dispnew.c (flush_stdout):
2287 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
2288 Mark as externally visible.
2289 * dispnew.c (check_window_matrix_pointers): Now static.
2290 * dispnew.c (window_to_frame_vpos):
2291 * xfns.c (unwind_create_frame):

2295 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
2296 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
2297 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
2298 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
2300 (debug_method_add): Use va_list and vsprintf rather than relying
2301 on undefined behavior with wrong number of arguments.
2302 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
2303 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
2304 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
2305 since we're not interested in debugging glyphs with old libraries.
2306 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
2307 GCC 4.6.0's static checking.
2309 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
2311 Integer overflow and signedness fixes (Bug#8873).
2312 A few related buffer overrun fixes, too.

2343 Use ptrdiff_t, not int, for sizes.
2344 (overlays_at, overlays_in): Check for size-calculation overflow.
2346 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
2348 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
2349 (x_session_initialize): Do not assume string length fits in int.
2351 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
2352 This is unlikely, but can occur if DPI is outlandish.
2354 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
2355 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
2357 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
2358 * xrdb.c (magic_file_p, search_magic_path):
2359 Omit last arg SUFFIX; it was always 0. All callers changed.
2360 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
2362 * xfont.c (xfont_match): Avoid need for strlen.
2364 * xfns.c: Don't assume strlen fits in int.
2365 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
2367 * xdisp.c (message_log_check_duplicate): Return intmax_t,
2368 not unsigned long, as we prefer signed integers. All callers changed.
2369 Detect integer overflow in repeat count.
2370 (message_dolog): Don't assume print length fits in 39 bytes.
2371 (display_mode_element): Don't assume strlen fits in int.
2373 * termcap.c: Don't assume sizes fit in int and never overflow.
2374 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
2375 (gobble_line): Check for size-calculation overflow.
2377 * minibuf.c (Fread_buffer):
2378 * lread.c (intern, intern_c_string):
2379 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
2380 Don't assume string length fits in int.
2382 * keyboard.c (parse_tool_bar_item):
2383 * gtkutil.c (style_changed_cb): Avoid need for strlen.
2385 * font.c: Don't assume string length fits in int.
2386 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
2387 Use ptrdiff_t, not int.
2388 (font_intern_prop): Don't assume string length fits in int.
2389 Don't assume integer property fits in fixnum.
2390 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
2392 * filelock.c: Fix some buffer overrun and integer overflow issues.
2393 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
2394 Reformulate so as not to need the command string.
2395 Invoke gzip -cd rather than gunzip, as it's more portable.
2396 (lock_info_type, lock_file_1, lock_file):
2397 Don't assume pid_t and time_t fit in unsigned long.
2398 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
2399 (current_lock_owner): Prefer signed type for sizes.
2400 Use memcpy, not strncpy, where memcpy is what is really wanted.
2401 Don't assume (via atoi) that time_t and pid_t fit in int.
2402 Check for time_t and/or pid_t out of range, e.g., via a network share.
2403 Don't alloca where an auto var works fine.
2405 * fileio.c: Fix some integer overflow issues.
2406 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
2407 Don't assume string length fits in int.
2408 (directory_file_name): Don't assume string length fits in long.
2409 (make_temp_name): Don't assume pid fits in int, or that its print
2410 length is less than 20.
2412 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
2414 * coding.c (make_subsidiaries): Don't assume string length fits in int.
2416 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
2418 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
2419 We prefer signed integers, even for size calculations.
2421 * emacs.c: Don't assume string length fits in 'int'.
2422 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
2423 (main): Don't invoke strlen when not needed.
2425 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
2426 (XD_DEBUG_MESSAGE): Don't waste a byte.
2428 * callproc.c (getenv_internal_1, getenv_internal)
2430 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
2432 * lread.c (invalid_syntax): Omit length argument.
2433 All uses changed. This doesn't fix a bug, but it simplifies the
2434 code away from its former Hollerith-constant appearance, and it's
2435 one less 'int' to worry about when looking at integer-overflow issues.
2436 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
2438 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
2439 This didn't break anything, but it didn't help either.
2440 It's confusing to put a bogus integer in a place where the actual
2441 value does not matter.
2442 (LIST_END_P): Remove unused macro and its bogus comment.
2443 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
2445 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
2446 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
2448 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
2449 We prefer signed types, and the value cannot exceed the EMACS_INT
2450 range anyway (because otherwise the length would not be representable).
2451 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
2452 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
2453 This avoids a GCC warning when WIDE_EMACS_INT.
2455 * indent.c (sane_tab_width): New function.
2456 (current_column, scan_for_column, Findent_to, position_indentation)
2457 (compute_motion): Use it. This is just for clarity.
2458 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
2460 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
2462 * lisp.h (lint_assume): New macro.
2463 * composite.c (composition_gstring_put_cache):
2464 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
2466 * editfns.c, insdel.c:
2467 Omit unnecessary forward decls, to simplify future changes.
2469 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
2471 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
2473 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
2474 Use much-faster test for byte-length change.
2475 Don't assume string byte-length fits in 'int'.
2476 Check that character arg fits in 'int'.
2477 (mapcar1): Declare byte as byte, for clarity.
2479 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
2481 * fns.c (concat): Catch string overflow earlier.
2482 Do not rely on integer wraparound.
2484 * dispextern.h (struct it.overlay_strings_charpos)
2485 (struct it.selective): Now EMACS_INT, not int.
2486 * xdisp.c (forward_to_next_line_start)
2487 (back_to_previous_visible_line_start)
2488 (reseat_at_next_visible_line_start, next_element_from_buffer):
2489 Don't arbitrarily truncate the value of 'selective' to int.
2491 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
2493 * composite.c: Don't truncate sizes to 'int'.
2494 (composition_gstring_p, composition_reseat_it)
2495 (composition_adjust_point): Use EMACS_INT, not int.
2496 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
2497 not EMACS_UINT, for indexes.
2499 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
2501 * buffer.c: Include <verify.h>.
2502 (struct sortvec.priority, struct sortstr.priority):
2503 Now EMACS_INT, not int.
2504 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
2505 (struct sortstr.size, record_overlay_string)
2506 (struct sortstrlist.size, struct sortlist.used):
2507 Don't truncate size to int.
2508 (record_overlay_string): Check for size-calculation overflow.
2509 (init_buffer_once): Check at compile-time, not run-time.
2511 2011-06-22 Jim Meyering <meyering@redhat.com>
2513 Don't leak an XBM-image-sized buffer
2514 * image.c (xbm_load): Free the image buffer after using it.
2516 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
2519 * composite.c (find_automatic_composition): Omit needless 'return 0;'
2520 that Sun C diagnosed.
2521 * fns.c (secure_hash): Fix pointer signedness issue.
2522 * intervals.c (static_offset_intervals): New function.
2523 (offset_intervals): Use it.
2525 2011-06-21 Leo Liu <sdl.web@gmail.com>
2528 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
2531 * fns.c (secure_hash): Rename from crypto_hash_function and change
2532 the first arg to accept symbols.
2533 (Fsecure_hash): New primitive.
2534 (syms_of_fns): New symbols.
2536 2011-06-20 Deniz Dogan <deniz@dogan.se>
2538 * process.c (Fset_process_buffer): Clarify return value in
2541 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
2543 * dispnew.c (add_window_display_history): Use BVAR.
2545 * xdisp.c (debug_method_add): Use BVAR.
2546 (check_window_end, dump_glyph_matrix, dump_glyph)
2547 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
2549 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
2552 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
2553 check till after the cache is created in init_frame_faces.
2555 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
2557 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
2559 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
2561 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
2562 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
2563 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
2565 Improve buffer-overflow checking (Bug#8873).
2566 * fileio.c (Finsert_file_contents):
2567 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
2568 Remove the old (too-loose) buffer overflow checks.
2569 They weren't needed, since make_gap checks for buffer overflow.
2570 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
2571 The old code merely checked for Emacs fixnum overflow, and relied
2572 on undefined (wraparound) behavior. The new code avoids undefined
2573 behavior, and also checks for ptrdiff_t and/or size_t overflow.
2575 * editfns.c (Finsert_char): Don't dump core with very negative counts.
2576 Tune. Don't use wider integers than needed. Don't use alloca.
2577 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
2579 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
2581 * insdel.c, lisp.h (buffer_overflow): New function.
2582 (insert_from_buffer_1, replace_range, replace_range_2):
2583 * insdel.c (make_gap_larger):
2584 * editfns.c (Finsert_char):
2585 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
2587 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
2589 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
2591 Integer overflow and signedness fixes (Bug#8873).
2593 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
2594 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
2596 * fileio.c: Don't assume EMACS_INT fits in off_t.
2597 (emacs_lseek): New static function.
2598 (Finsert_file_contents, Fwrite_region): Use it.
2599 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
2601 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
2603 * fns.c: Don't overflow int when computing a list length.
2604 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
2605 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
2606 truncation on 64-bit hosts. Check for QUIT every
2607 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
2608 faster and is responsive enough.
2609 (Flength): Report an error instead of overflowing an integer.
2610 (Fsafe_length): Return a float if the value is not representable
2611 as a fixnum. This shouldn't happen except in contrived situations.
2612 (Fnthcdr, Fsort): Don't assume list length fits in int.
2613 (Fcopy_sequence): Don't assume vector length fits in int.
2615 * alloc.c: Check that resized vectors' lengths fit in fixnums.
2616 (header_size, word_size): New constants.
2617 (allocate_vectorlike): Don't check size overflow here.
2618 (allocate_vector): Check it here instead, since this is the only
2619 caller of allocate_vectorlike that could cause overflow.
2620 Check that the new vector's length is representable as a fixnum.
2622 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
2623 The previous code was bogus. For example, next_almost_prime (32)
2624 returned 39, which is undesirable as it is a multiple of 3; and
2625 next_almost_prime (24) returned 25, which is a multiple of 5 so
2626 why was the code bothering to check for multiples of 7?
2628 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
2630 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
2632 Variadic C functions now count arguments with ptrdiff_t.
2633 This partly undoes my 2011-03-30 change, which replaced int with size_t.
2634 Back then I didn't know that the Emacs coding style prefers signed int.
2635 Also, in the meantime I found a few more instances where arguments
2636 were being counted with int, which may truncate counts on 64-bit
2637 machines, or EMACS_INT, which may be unnecessarily wide.
2638 * lisp.h (struct Lisp_Subr.function.aMANY)
2639 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
2640 Arg counts are now ptrdiff_t, not size_t.
2641 All variadic functions and their callers changed accordingly.
2642 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
2643 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
2644 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
2645 * callint.c (Fcall_interactively): Check arg count for overflow,
2646 to avoid potential buffer overrun. Use signed char, not 'int',
2647 for 'varies' array, so that we needn't bother to check its size
2648 calculation for overflow.
2649 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
2650 * eval.c (apply_lambda):
2651 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
2652 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
2653 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
2655 * callint.c (Fcall_interactively): Don't use index var as event count.
2657 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
2658 * mem-limits.h (SIZE): Remove; no longer used.
2660 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
2662 Remove unnecessary casts.
2663 * xterm.c (x_term_init):
2664 * xfns.c (x_set_border_pixel):
2665 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
2666 These aren't needed now that we assume ANSI C.
2668 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
2669 It's more likely to cause problems (due to unsigned overflow)
2672 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
2674 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
2676 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
2678 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
2680 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
2682 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
2684 GLYPH_CODE_FACE returns EMACS_INT, not int.
2685 * dispextern.h (merge_faces):
2686 * xfaces.c (merge_faces):
2687 * xdisp.c (get_next_display_element, next_element_from_display_vector):
2688 Don't assume EMACS_INT fits in int.
2690 * character.h (CHAR_VALID_P): Remove unused parameter.
2691 * fontset.c, lisp.h, xdisp.c: All uses changed.
2693 * editfns.c (Ftranslate_region_internal): Omit redundant test.
2695 * fns.c (concat): Minor tuning based on overflow analysis.
2696 This doesn't fix any bugs. Use int to hold character, instead
2697 of constantly refetching from Emacs object. Use XFASTINT, not
2698 XINT, for value known to be a character. Don't bother comparing
2699 a single byte to 0400, as it's always less.
2701 * floatfns.c (Fexpt):
2702 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
2704 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
2707 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
2709 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
2710 Without this fix, on a 64-bit host (aset S 0 4294967386) would
2711 incorrectly succeed when S was a string, because 4294967386 was
2712 truncated before it was used.
2714 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
2715 Otherwise, an out-of-range integer could cause undefined behavior
2718 * composite.c: Use int, not EMACS_INT, for characters.
2719 (fill_gstring_body, composition_compute_stop_pos): Use int, not
2720 EMACS_INT, for values that are known to be in character range.
2721 This doesn't fix any bugs but is the usual style inside Emacs and
2722 may generate better code on 32-bit machines.
2724 Make sure a 64-bit char is never passed to ENCODE_CHAR.
2725 This is for reasons similar to the recent CHAR_STRING fix.
2726 * charset.c (Fencode_char): Check that character arg is actually
2727 a character. Pass an int to ENCODE_CHAR.
2728 * charset.h (ENCODE_CHAR): Verify that the character argument is no
2729 wider than 'int', as a compile-time check to prevent future regressions
2732 * character.c (char_string): Remove unnecessary casts.
2734 Make sure a 64-bit char is never passed to CHAR_STRING.
2735 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
2736 by silently ignoring the top 32 bits, allowing some values
2737 that were far too large to be valid characters.
2738 * character.h: Include <verify.h>.
2739 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
2740 arguments are no wider than unsigned, as a compile-time check
2741 to prevent future regressions in this area.
2743 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
2744 (Fsubst_char_in_region):
2746 * xdisp.c (decode_mode_spec_coding):
2747 Adjust to CHAR_STRING's new requirement.
2748 * editfns.c (Finsert_char, Fsubst_char_in_region):
2749 * fns.c (concat): Check that character args are actually
2750 characters. Without this test, these functions did the wrong
2751 thing with wildly out-of-range values on 64-bit hosts.
2753 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
2754 These casts should not be needed on 32-bit hosts, either.
2755 * keyboard.c (read_char):
2756 * lread.c (Fload): Remove casts to unsigned.
2758 * lisp.h (UNSIGNED_CMP): New macro.
2759 This fixes comparison bugs on 64-bit hosts.
2760 (ASCII_CHAR_P): Use it.
2761 * casefiddle.c (casify_object):
2762 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
2763 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
2764 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
2765 * dispextern.h (FACE_FROM_ID):
2766 * keyboard.c (read_char): Use UNSIGNED_CMP.
2768 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
2769 not to EMACS_INT, to avoid GCC warning.
2771 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
2773 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
2774 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
2775 isn't needed on 32-bit machines.
2777 * buffer.c (Fgenerate_new_buffer_name):
2778 Use EMACS_INT for count, not int.
2779 (advance_to_char_boundary): Return EMACS_INT, not int.
2781 * data.c (Qcompiled_function): Now static.
2783 * window.c (window_body_lines): Now static.
2785 * image.c (gif_load): Rename local to avoid shadowing.
2787 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
2788 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
2789 * alloc.c (make_save_value): Integer argument is now of type
2791 (mark_object): Use ptrdiff_t, not int.
2792 * lisp.h (pD): New macro.
2793 * print.c (print_object): Use it.
2795 * alloc.c: Use EMACS_INT, not int, to count objects.
2796 (total_conses, total_markers, total_symbols, total_vector_size)
2797 (total_free_conses, total_free_markers, total_free_symbols)
2798 (total_free_floats, total_floats, total_free_intervals)
2799 (total_intervals, total_strings, total_free_strings):
2800 Now EMACS_INT, not int. All uses changed.
2801 (Fgarbage_collect): Compute overall total using a double, so that
2802 integer overflow is less likely to be a problem. Check for overflow
2803 when converting back to an integer.
2804 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
2805 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
2806 These were 'int' variables that could overflow on 64-bit hosts;
2807 they were never used, so remove them instead of repairing them.
2808 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
2809 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
2810 Previously, this ceilinged at INT_MAX, but that doesn't work on
2812 (allocate_pseudovector): Don't use EMACS_INT when int would do.
2814 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
2815 (allocate_vectorlike): Check for ptrdiff_t overflow.
2816 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
2817 when a (possibly-narrower) signed value would do just as well.
2818 We prefer using signed arithmetic, to avoid comparison confusion.

3281 * keymap.c (access_keymap, silly_event_symbol_error):
3282 XUINT -> XFASTINT, since the integer must be nonnegative.
3283 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
3284 since it makes no difference and we prefer signed.
3285 * keyboard.c (record_char): Use XUINT when all the neighbors do.
3286 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

3296 (SPARE_MEMORY): Always define.
3297 (LARGE_REQUEST): Remove.
3298 (memory_full): Use SPARE_MEMORY rather than LARGE_REQUEST.
3300 2011-06-06 Martin Rudalics <rudalics@gmx.at>
3302 * lisp.h: Move EXFUNS for Fframe_root_window,
3303 Fframe_first_window and Fset_frame_selected_window to window.h.
3305 * window.h: Move EXFUNS for Fframe_root_window,
3306 Fframe_first_window and Fset_frame_selected_window here from

3310 (Fframe_root_window, Fframe_selected_window)
3311 (Fset_frame_selected_window): Move to window.c.
3312 (Factive_minibuffer_window): Move to minibuf.c.
3313 (Fother_visible_frames_p): New function.

3327 or arbitrary window as argument. Update doc-strings.
3328 (Fminibuffer_window): Move up in code.
3329 (Fwindow_minibuffer_p): Move up in code and simplify.
3330 (Fset_frame_selected_window): Move here from frame.c.

3337 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
3338 Do not assume that spare memory exists; that assumption is valid
3339 only if SYSTEM_MALLOC.
3340 (LARGE_REQUEST): New macro, so that the issue of large requests
3341 is separated from the issue of spare memory.
3343 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
3345 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

3362 2011-06-05 Juanma Barranquero <lekktu@gmail.com>
3364 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
3366 2011-06-04 Chong Yidong <cyd@stupidchicken.com>

3370 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
3372 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
3373 Obey Vx_select_enable_clipboard_manager. Catch errors in
3374 x_clipboard_manager_save (Bug#8779).
3375 (Vx_select_enable_clipboard_manager): New variable.
3376 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
3378 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
3380 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
3382 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3384 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
3385 in the current matrix if keep_current_p is non-zero.
3387 2011-06-04 Eli Zaretskii <eliz@gnu.org>
3389 * bidi.c (bidi_level_of_next_char): Fix last change.
3391 2011-06-03 Eli Zaretskii <eliz@gnu.org>
3393 Support bidi reordering of text covered by display properties.
3395 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
3396 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
3397 (bidi_cache_search, bidi_cache_iterator_state)
3398 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
3399 (bidi_level_of_next_char, bidi_move_to_visually_next):
3400 Support character positions inside a run of characters covered by a
3402 (bidi_paragraph_init, bidi_resolve_explicit_1)
3403 (bidi_level_of_next_char): Call bidi_fetch_char and
3404 bidi_fetch_char_advance instead of FETCH_CHAR and
3406 (bidi_init_it): Initialize new members.
3407 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
3409 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
3410 instead of using explicit *_CHAR codes.
3411 (bidi_resolve_explicit, bidi_resolve_weak):
3412 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
3413 bidirectional text is supported only in multibyte buffers.
3414 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
3415 it to initialize the frame_window_p member of struct bidi_it.
3416 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
3417 (bidi_resolve_explicit, bidi_resolve_weak)
3418 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
3419 bidi_it->nchars is non-positive.
3420 (bidi_level_of_next_char): Don't try to lookup the cache for the
3421 next/previous character if nothing is cached there yet, or if we
3422 were just reseat()'ed to a new position.
3424 * xdisp.c (set_cursor_from_row): Set start and stop points
3425 according to the row's direction when priming the loop that looks
3426 for the glyph on which to display cursor.
3427 (single_display_spec_intangible_p): Function deleted.
3428 (display_prop_intangible_p): Reimplement to call
3429 handle_display_spec instead of single_display_spec_intangible_p.
3430 Accept 3 additional arguments needed by handle_display_spec.
3431 This fixes incorrect cursor motion across display property with complex
3432 values: lists, `(when COND...)' forms, etc.
3433 (single_display_spec_string_p): Support property values that are
3434 lists with the argument STRING its top-level element.
3435 (display_prop_string_p): Fix the condition for processing a
3436 property that is a list to be consistent with handle_display_spec.
3437 (handle_display_spec): New function, refactored from the
3438 last portion of handle_display_prop.
3439 (compute_display_string_pos): Accept additional argument
3440 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
3441 value of a `display' property is a "replacing spec".
3442 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
3443 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
3444 the display property, but just return a value indicating whether
3445 the display property will replace the characters it covers.
3446 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
3447 frame_window_p members of struct bidi_it.
3448 (compute_display_string_pos, compute_display_string_end):
3450 (push_it): Accept second argument POSITION, where pop_it should
3451 jump to continue iteration.
3452 (reseat_1): Initialize bidi_it.disp_pos.
3454 * keyboard.c (adjust_point_for_property): Adjust the call to
3455 display_prop_intangible_p to its new signature.
3457 * dispextern.h (struct bidi_it): New member frame_window_p.
3458 (bidi_init_it): Update prototypes.
3459 (display_prop_intangible_p): Update prototype.
3460 (compute_display_string_pos, compute_display_string_end):
3462 (struct bidi_it): New members nchars and disp_pos. ch_len is now
3465 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
3467 Malloc failure behavior now depends on size of allocation.
3468 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
3469 * lisp.h: Change signatures accordingly.
3470 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
3471 All callers changed. (Bug#8762)
3473 * gnutls.c: Use Emacs's memory allocators.
3474 Without this change, the gnutls library would invoke malloc etc.
3475 directly, which causes problems on non-SYNC_INPUT hosts, and which
3476 runs afoul of improving memory_full behavior. (Bug#8761)
3477 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
3478 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
3479 xfree instead of the default malloc, realloc, free.
3480 (Fgnutls_boot): No need to check for memory allocation failure,
3481 since xmalloc does that for us.
3483 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
3484 * category.c (hash_get_category_set):
3485 * ccl.c (ccl_driver):
3486 * charset.c (Fdefine_charset_internal):

3497 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
3498 (Fsxhash, Fgethash, Fputhash, Fmaphash):
3499 * image.c (make_image, search_image_cache, lookup_image)
3500 (xpm_put_color_table_h):
3501 * lisp.h (struct Lisp_Hash_Table):
3502 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
3503 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
3504 for hashes and hash indexes, instead of 'unsigned' and 'int'.
3505 * alloc.c (allocate_vectorlike):
3506 Check for overflow in vector size calculations.
3507 * ccl.c (ccl_driver):
3508 Check for overflow when converting EMACS_INT to int.
3509 * fns.c, image.c: Remove unnecessary static decls that would otherwise
3510 need to be updated by these changes.
3511 * fns.c (make_hash_table, maybe_resize_hash_table):
3512 Check for integer overflow with large hash tables.
3513 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
3514 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
3515 (SXHASH_REDUCE): New macro.
3516 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
3517 Use it instead of discarding useful hash info with large hash values.
3518 (sxhash_float): New function.
3519 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
3520 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
3521 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
3522 Rewrite to use FIXNUM_BITS, as this simplifies things.
3523 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
3524 Adjust signatures to match updated version of code.
3525 (consing_since_gc): Now EMACS_INT, since a single hash table can
3526 use more than INT_MAX bytes.
3528 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
3530 Make it possible to build with GCC-4.6+ -O2 -flto.
3532 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
3534 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
3536 * minibuf.c (get_minibuffer, read_minibuf_unwind):
3537 Call minibuffer-inactive-mode.
3539 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
3541 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
3542 Update dependencies.
3544 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3546 * data.c (init_data): Remove code for UTS, this system is not
3549 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3551 Don't force ./temacs to start in terminal mode.
3553 * frame.c (make_initial_frame): Initialize faces in all cases, not
3554 only when CANNOT_DUMP is defined.
3555 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
3557 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3559 * dispnew.c (add_window_display_history): Use const for the string
3560 pointer. Remove declaration, not needed.
3562 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3564 Use 'inline', not 'INLINE'.
3565 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
3566 * alloc.c, fontset.c (INLINE): Remove.
3567 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
3568 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
3569 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
3570 * gmalloc.c (register_heapinfo): Use inline unconditionally.
3571 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
3573 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3575 Make it possible to run ./temacs.
3577 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
3578 syms_of_callproc does the same thing. Remove test for
3579 "initialized", do it in the caller.
3580 * emacs.c (main): Avoid calling set_initial_environment when dumping.
3582 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
3584 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
3585 (read_minibuf): Use get_minibuffer.
3586 (syms_of_minibuf): Use DEFSYM.
3587 (Qmetadata): New var.
3588 * data.c (Qbuffer): Don't make it static.
3589 (syms_of_data): Use DEFSYM.
3591 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3593 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
3594 (CCL_CODE_MIN): New macro.
3596 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
3598 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
3600 * eval.c (Qdebug): Now static.
3601 * lisp.h (Qdebug): Remove decl. This reverts a part of the
3602 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
3603 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
3605 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3607 * image.c: Various fixes to ImageMagick code comments.
3608 (Fimagemagick_types): Doc fix.
3610 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
3612 Minor fixes prompted by GCC 4.6.0 warnings.
3614 * xselect.c (converted_selections, conversion_fail_tag): Now static.
3616 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
3617 (x_clipboard_manager_save_all): Move extern decl to ...
3618 * xterm.h: ... here, so that it can be checked for consistency.
3620 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3622 * xselect.c (x_clipboard_manager_save_frame)
3623 (x_clipboard_manager_save_all): New functions.
3624 (Fx_clipboard_manager_save): Lisp function deleted.
3626 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
3627 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
3629 * xterm.h: Update prototype.
3631 2011-05-28 William Xu <william.xwl@gmail.com>
3633 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
3636 2011-05-28 Jim Meyering <meyering@redhat.com>
3638 Avoid a sign-extension bug in crypto_hash_function.
3639 * fns.c (to_uchar): Define.
3640 (crypto_hash_function): Use it to convert some newly-signed
3641 variables to unsigned, to avoid sign-extension bugs. For example,
3642 without this change, (md5 "truc") would evaluate to
3643 45723a2aff78ff4fff7fff1114760e62 rather than the expected
3644 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
3645 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
3647 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3649 Integer overflow fixes.
3651 * dbusbind.c: Serial number integer overflow fixes.
3652 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
3653 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
3654 to hold a serial number that is too large for a fixnum.
3655 (Fdbus_method_return_internal, Fdbus_method_error_internal):
3656 Check for serial numbers out of range. Decode any serial number
3657 that was so large that it became a float. (Bug#8722)
3659 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
3660 (Fdbus_call_method, Fdbus_call_method_asynchronously):
3661 Use XFASTINT rather than XUINT when numbers are nonnegative.
3662 (xd_append_arg, Fdbus_method_return_internal):
3663 (Fdbus_method_error_internal): Likewise. Also, for unsigned
3664 arguments, check that Lisp number is nonnegative, rather than
3665 silently wrapping negative numbers around. (Bug#8722)
3666 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
3669 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
3671 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
3673 ccl: add integer overflow checks
3674 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
3675 (IN_INT_RANGE): New macros.
3676 (ccl_driver): Use them to check for integer overflow when
3677 decoding a CCL program. Many of the new checks are whether XINT (x)
3678 fits in int; it doesn't always, on 64-bit hosts. The new version
3679 doesn't catch all possible integer overflows, but it's an
3680 improvement. (Bug#8719)
3682 * alloc.c (make_event_array): Use XINT, not XUINT.
3683 There's no need for unsigned here.
3685 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
3686 This follows up to the 2011-05-06 change that substituted uintptr_t
3687 for EMACS_INT. This case wasn't caught back then.
3689 Rework Fformat to avoid integer overflow issues.
3690 * editfns.c: Include <float.h> unconditionally, as it's everywhere
3691 now (part of C89). Include <verify.h>.
3692 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
3693 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
3694 (Fformat): Avoid the prepass trying to compute sizes; it was only
3695 approximate and thus did not catch overflow reliably. Instead, walk
3696 through the format just once, formatting and computing sizes as we go,
3697 checking for integer overflow at every step, and allocating a larger
3698 buffer as needed. Keep track separately whether the format is
3699 multibyte. Keep only the most-recently calculated precision, rather
3700 than them all. Record whether each argument has been converted to
3701 string. Use EMACS_INT, not int, for byte and char and arg counts.
3702 Support field widths and precisions larger than INT_MAX. Avoid
3703 sprintf's undefined behavior with conversion specifications such as %#d
3704 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
3705 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
3706 formatting out-of-range floating point numbers with int
3709 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
3711 * data.c: Avoid integer truncation in expressions involving floats.
3712 * data.c: Include <intprops.h>.
3713 (arith_driver): When there's an integer overflow in an expression
3714 involving floating point, convert the integers to floating point
3715 so that the resulting value does not suffer from catastrophic
3716 integer truncation. For example, on a 64-bit host (* 4
3717 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
3718 Do not rely on undefined behavior after integer overflow.
3720 merge count_size_as_multibyte, parse_str_to_multibyte
3721 * character.c, character.h (count_size_as_multibyte):
3722 Rename from parse_str_to_multibyte; all uses changed.
3723 Check for integer overflow.
3724 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
3725 since it's now a duplicate of the other. This is more of
3726 a character than a buffer op, so better that it's in character.c.
3727 * fns.c, print.c: Adjust to above changes.
3729 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
3731 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.

3736 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
3737 (x_clipboard_manager_save): Now static.
3738 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
3740 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3741 (crypto_hash_function): Now static.
3742 Fix pointer signedness problems. Avoid unnecessary initializations.
3744 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
3746 * termhooks.h (Vselection_alist): Make it terminal-local.
3748 * terminal.c (create_terminal): Initialize it.
3750 * xselect.c: Support for clipboard managers.
3751 (Vselection_alist): Move to termhooks.h as terminal-local var.
3752 (LOCAL_SELECTION): New macro.
3753 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
3754 (symbol_to_x_atom): Remove gratuitous arg.
3755 (x_handle_selection_request, lisp_data_to_selection_data)
3756 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
3757 (x_own_selection, x_get_local_selection, x_convert_selection):
3758 New arg, specifying work frame. Use terminal-local Vselection_alist.
3759 (some_frame_on_display): Delete unused function.
3760 (Fx_own_selection_internal, Fx_get_selection_internal)
3761 (Fx_disown_selection_internal, Fx_selection_owner_p)
3762 (Fx_selection_exists_p): New optional frame arg.
3763 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
3764 (x_handle_selection_clear): Don't treat other terminals with the
3765 same keyboard specially. Use the terminal-local Vselection_alist.
3766 (x_clear_frame_selections): Use Frun_hook_with_args.
3768 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
3770 * xterm.h: Add support for those atoms.
3772 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
3774 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
3775 (converted_selections, conversion_fail_tag): New global variables.
3776 (x_selection_request_lisp_error): Free the above.
3777 (x_get_local_selection): Remove unnecessary code.
3778 (x_reply_selection_request): Args changed; handle arbitrary array
3779 of converted selections stored in converted_selections.
3780 Separate the XChangeProperty and SelectionNotify steps.
3781 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
3782 (x_convert_selection): New function.
3783 (x_handle_selection_event): Simplify.
3784 (x_get_foreign_selection): Don't ignore incoming requests while
3785 waiting for an answer; this will fail when we implement
3786 SAVE_TARGETS, and seems unnecessary anyway.
3787 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
3788 (Vx_sent_selection_functions): Doc fix.
3790 2011-05-26 Leo Liu <sdl.web@gmail.com>
3792 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
3794 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3796 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
3798 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
3799 for fringe update if it has periodic bitmap.
3800 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
3801 and fringe_bitmap_periodic_p.
3803 * fringe.c (get_fringe_bitmap_data): New function.
3804 (draw_fringe_bitmap_1, update_window_fringes): Use it.
3805 (update_window_fringes): Record periodicity of fringe bitmap in glyph
3806 row. Mark glyph row for fringe update if periodicity changed.
3808 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
3809 for fringe update unless it has periodic bitmap.
3811 2011-05-25 Kenichi Handa <handa@m17n.org>
3813 * xdisp.c (get_next_display_element): Set correct it->face_id for
3814 a static composition.
3816 2011-05-24 Leo Liu <sdl.web@gmail.com>
3819 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
3821 * fns.c (crypto_hash_function, Fsha1): New function.
3822 (Fmd5): Use crypto_hash_function.
3823 (syms_of_fns): Add Ssha1.
3825 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3827 * gnutls.c: Remove unused macros.
3828 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
3829 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
3830 Remove macros that are defined and never used.
3831 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
3833 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3835 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
3836 (Fx_get_selection_internal): Minor cleanup.
3837 (Fx_own_selection_internal): Rename arguments for consistency with
3840 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3842 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
3844 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3846 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
3848 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3850 * dispnew.c (scrolling_window): Don't exclude the case that the
3851 last enabled row in the desired matrix touches the bottom boundary.
3853 2011-05-21 Glenn Morris <rgm@gnu.org>
3855 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
3856 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
3857 and add some more files.
3859 2011-05-20 Eli Zaretskii <eliz@gnu.org>
3861 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
3862 report_file_error introduced by the change from 2011-05-07.
3864 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
3866 * systime.h (Time): Define only if emacs is defined.
3867 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
3868 where the include path doesn't have X11/X.h by default. See
3869 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
3871 2011-05-20 Kenichi Handa <handa@m17n.org>
3873 * composite.c (find_automatic_composition): Fix previous change.
3875 2011-05-20 Glenn Morris <rgm@gnu.org>
3877 * lisp.mk: New file, split from Makefile.in.
3878 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
3879 (shortlisp): Remove.
3880 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
3882 2011-05-19 Glenn Morris <rgm@gnu.org>
3884 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
3885 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
3886 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
3887 (lisp): Set the order to that of loadup.el.
3888 (shortlisp): Make it a copy of $lisp.
3889 (SOME_MACHINE_LISP): Remove.
3890 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
3891 Use just $shortlisp, not $SOME_MACHINE_LISP too.
3893 2011-05-18 Kenichi Handa <handa@m17n.org>
3895 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
3896 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
3897 (find_automatic_composition): Mostly rewrite for efficiency.
3899 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
3901 * makefile.w32-in: Update dependencies.
3903 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
3905 * menu.c: Include limits.h (fixes the MS-Windows build broken by
3906 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
3908 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
3910 Fix some integer overflow issues, such as string length overflow.
3912 * insdel.c (count_size_as_multibyte): Check for string overflow.
3914 * character.c (lisp_string_width): Check for string overflow.
3915 Use EMACS_INT, not int, for string indexes and lengths; in
3916 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
3917 the resulting string length overflows an EMACS_INT; instead,
3918 report a string overflow if no precision given. When checking for
3919 precision exhaustion, use a check that cannot possibly have
3920 integer overflow. (Bug#8675)
3921 * character.h (lisp_string_width): Adjust to new signature.
3923 * alloc.c (string_overflow): New function.
3924 (Fmake_string): Use it. This doesn't change behavior, but saves
3925 a few bytes and will simplify future changes.
3926 * character.c (string_escape_byte8): Likewise.
3927 * lisp.h (string_overflow): New decl.
3929 Fixups, following up to the user-interface timestamp change.
3930 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
3931 for UI timestamps, instead of unsigned long.
3932 * msdos.c (mouse_get_pos): Likewise.
3933 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
3934 * w32gui.h (Time): Define by including "systime.h" rather than by
3935 declaring it ourselves. (Bug#8664)
3937 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
3938 * image.c (clear_image_cache): Likewise.
3940 * term.c (term_mouse_position): Don't assume time_t wraparound.
3942 Be more systematic about user-interface timestamps.
3943 Before, the code sometimes used 'Time', sometimes 'unsigned long',
3944 and sometimes 'EMACS_UINT', to represent these timestamps.
3945 This change causes it to use 'Time' uniformly, as that's what X uses.
3946 This makes the code easier to follow, and makes it easier to catch
3947 integer overflow bugs such as Bug#8664.
3948 * frame.c (Fmouse_position, Fmouse_pixel_position):
3949 Use Time, not unsigned long, for user-interface timestamps.
3950 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
3951 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
3952 * keyboard.h (last_event_timestamp): Likewise.
3953 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
3954 * menu.h (xmenu_show): Likewise.
3955 * term.c (term_mouse_position): Likewise.
3956 * termhooks.h (struct input_event.timestamp): Likewise.
3957 (struct terminal.mouse_position_hook): Likewise.
3958 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
3959 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
3960 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
3961 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
3963 * menu.h, termhooks.h: Include "systime.h", for Time.
3965 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
3966 Don't assume that the difference between two unsigned long values
3967 can fit into an integer. At this point, we know button_down_time
3968 <= event->timestamp, so the difference must be nonnegative, so
3969 there's no need to cast the result if double-click-time is
3970 nonnegative, as it should be; check that it's nonnegative, just in
3971 case. This bug is triggered when events are more than 2**31 ms
3972 apart (about 25 days). (Bug#8664)
3974 * xselect.c (last_event_timestamp): Remove duplicate decl.
3975 (x_own_selection): Remove needless cast to unsigned long.
3977 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
3978 that always fit in int. Use a sentinel instead of a counter, to
3979 avoid a temp and to allay GCC's concerns about possible int overflow.
3980 * frame.h (struct frame): Use int for menu_bar_items_used
3981 instead of EMACS_INT, since it always fits in int.
3983 * menu.c (grow_menu_items): Check for int overflow.
3985 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
3987 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
3988 Before, the code was not consistent. These values cannot exceed
3989 2**31 - 1 so there's no need to make them unsigned.
3990 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
3991 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
3992 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
3994 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
3996 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
3997 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
3998 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
3999 presumably because the widths might not match.
4001 * window.c (size_window): Avoid needless test at loop start.
4003 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
4005 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
4007 2011-05-12 Drew Adams <drew.adams@oracle.com>
4009 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
4011 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4013 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
4014 `width' to `bar_area_x' and `bar_area_width', respectively.
4015 (x_scroll_run): Take account of fringe background extension.
4017 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
4018 Rename local vars `left' and `width' to `bar_area_x' and
4019 `bar_area_width', respectively.
4020 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
4021 background extension.
4023 2011-05-10 Jim Meyering <meyering@redhat.com>
4025 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
4027 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
4029 * image.c (Finit_image_library): Return t for built-in image types,
4030 like pbm and xbm. (Bug#8640)
4032 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
4034 * w32menu.c (set_frame_menubar): Fix submenu allocation.
4036 2011-05-07 Eli Zaretskii <eliz@gnu.org>
4038 * w32console.c (Fset_screen_color): Doc fix.
4039 (Fget_screen_color): New function.
4040 (syms_of_ntterm): Defsubr it.
4042 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
4043 unlink the temporary file if Fcall_process didn't create it in the
4045 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
4046 child process will be redirected to a file specified with `:file'.
4047 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
4048 cue to call_process_cleanup not to close that handle.
4050 2011-05-07 Ben Key <bkey76@gmail.com>
4052 * makefile.w32-in: The bootstrap-temacs rule now makes use of
4053 one of two shell specific rules, either bootstrap-temacs-CMD or
4054 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
4055 to the previous implementation of the bootstrap-temacs rule.
4056 The bootstrap-temacs-CMD rule is similar to the previous
4057 implementation of the bootstrap-temacs rule except that it
4058 makes use of the ESC_CFLAGS variable instead of the CFLAGS
4061 These changes, along with some changes to nt/configure.bat,
4062 nt/gmake.defs, and nt/nmake.defs, are required to extend my
4063 earlier fix to add support for --cflags and --ldflags options
4064 that include quotes so that it works whether make uses cmd or
4067 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
4069 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
4070 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
4072 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
4073 a string. Handle both cases.
4074 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
4075 (Fdbus_register_method): Use Qinvalid_function.
4077 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
4079 * makefile.w32-in: Update dependencies.
4080 (LISP_H): Add inttypes.h and stdin.h.
4081 (PROCESS_H): Add unistd.h.
4083 2011-05-06 Eli Zaretskii <eliz@gnu.org>
4085 * lread.c: Include limits.h (fixes the MS-Windows build broken by
4086 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
4088 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
4090 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
4092 * term.c (vfatal): Remove stray call to va_end.
4093 It's not needed and the C Standard doesn't allow it here anyway.
4095 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
4096 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
4098 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
4101 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
4103 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
4105 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
4107 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
4109 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
4111 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
4112 * charset.c (Fdefine_charset_internal): Don't initialize
4113 charset.code_space[15]. The value was garbage, on hosts with
4114 32-bit int (Bug#8600).
4116 * lread.c (read_integer): Be more consistent with string-to-number.
4117 Use string_to_number to do the actual conversion; this avoids
4118 rounding errors and fixes some other screwups. Without this fix,
4119 for example, #x1fffffffffffffff was misread as -2305843009213693952.
4120 (digit_to_number): Move earlier, for benefit of read_integer.
4121 Return -1 if the digit is out of range for the base, -2 if it is
4122 not a digit in any supported base. (Bug#8602)
4124 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
4126 * dispnew.c (scrolling_window): Return 1 if we scrolled,
4127 to match comment at start of function. This also removes a
4128 GCC warning about overflow in a 32+64-bit port.
4130 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
4132 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
4133 Reported by Stefan Monnier in
4134 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
4135 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
4136 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
4138 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
4139 (EMACS_UINTPTR): Likewise, with uintptr_t.
4141 * lisp.h: Prefer 64-bit EMACS_INT if available.
4142 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
4143 on 32-bit hosts that have 64-bit int, so that they can access
4145 However, temporarily disable this change unless the temporary
4146 symbol WIDE_EMACS_INT is defined.
4148 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
4150 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
4151 This removes an assumption that EMACS_INT and long are the same
4152 width as pointers. The assumption is true for Emacs porting targets
4153 now, but we want to make other targets possible.
4154 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
4155 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
4156 In the rest of the code, change types of integers that hold casted
4157 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
4158 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
4159 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
4160 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
4161 No need to cast type when ORing.
4162 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
4163 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
4164 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
4165 assume EMACS_INT is the same width as char *.
4166 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
4167 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
4168 Remove no-longer-needed casts.
4169 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
4170 (xg_tool_bar_help_callback, xg_make_tool_item):
4171 Use EMACS_INTPTR to hold an integer
4172 that will be cast to void *; this can avoid a GCC warning
4173 if EMACS_INT is not the same width as void *.
4174 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
4175 * xdisp.c (display_echo_area_1, resize_mini_window_1):
4176 (current_message_1, set_message_1):
4177 Use a local to convert to proper width without a cast.
4178 * xmenu.c (dialog_selection_callback): Likewise.
4180 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
4181 Also, don't assume VALBITS / RAND_BITS is less than 5,
4182 and don't rely on undefined behavior when shifting a 1 left into
4184 * lisp.h (get_random): Change signature to match.
4186 * lread.c (hash_string): Use size_t, not int, for hash computation.
4187 Normally we prefer signed values; but hashing is special, because
4188 it's better to use unsigned division on hash table sizes so that
4189 the remainder is nonnegative. Also, size_t is the natural width
4190 for hashing into memory. The previous code used 'int', which doesn't
4191 retain enough info to hash well into very large tables.
4192 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
4194 * dbusbind.c: Don't possibly lose pointer info when converting.
4195 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
4196 Use XPNTR rather than XHASH, so that the high-order bits of
4197 the pointer aren't lost when converting through void *.
4199 * eval.c (Fautoload): Don't double-shift a pointer.
4201 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
4203 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
4205 * gnutls.c (DEF_GNUTLS_FN):
4206 * image.c (DEF_IMGLIB_FN): Make function pointers static.
4208 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
4210 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
4213 2011-05-05 Eli Zaretskii <eliz@gnu.org>
4215 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:

4224 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
4225 `gnutls_certificate_set_x509_key_file'.
4227 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
4229 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
4230 Update dependencies.
4232 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4234 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
4235 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
4236 Remove unused parameter `fildes'.

4239 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4241 Fix previous change: the library cache is defined in w32.c.
4242 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
4243 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
4245 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4247 Implement dynamic loading of GnuTLS on Windows.
4249 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.

4263 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
4264 (Fgnutls_available_p): New function.
4265 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
4266 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
4267 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
4269 * image.c: Include w32.h.
4270 (Vimage_type_cache): Delete.
4271 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
4272 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
4273 (w32_delayed_load): Move to w32.c.

4277 * w32.c (QCloaded_from, Vlibrary_cache): Define.
4278 (w32_delayed_load): Move from image.c. When loading a library, record
4279 its filename in the :loaded-from property of the library id.
4280 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
4281 Initialize and staticpro them.
4282 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
4284 * process.c: Include lisp.h before w32.h, not after.
4285 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
4286 instead of gnutls_record_check_pending.
4288 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
4290 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
4292 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
4293 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
4296 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
4298 * xterm.c (x_set_frame_alpha): Do not set property on anything
4299 else than FRAME_X_OUTER_WINDOW (Bug#8608).
4301 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
4303 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
4305 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
4307 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
4308 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

4322 (wait_for_termination, interruptible_wait_for_termination):
4323 Move after wait_for_termination_1.
4325 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
4327 * sysdep.c (interruptible_wait_for_termination): New function
4328 which is like wait_for_termination, but allows keyboard
4331 * callproc.c (Fcall_process): Add (:file "file") as an option for
4333 (Fcall_process_region): Ditto.
4335 2011-04-30 Eli Zaretskii <eliz@gnu.org>
4337 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
4338 rather than `XVECTOR (FOO)->size'.
4340 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
4341 inttypes.h, as a gnulib replacement is used if it not available in
4344 2011-04-21 Eli Zaretskii <eliz@gnu.org>
4346 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
4347 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
4348 of MOST_POSITIVE_FIXNUM. (Bug#8528)
4350 * coding.c (coding_alloc_by_realloc): Error out if destination
4351 will grow beyond MOST_POSITIVE_FIXNUM.
4352 (decode_coding_emacs_mule): Abort if there isn't enough place in
4353 charbuf for the composition carryover bytes. Reserve an extra
4354 space for up to 2 characters produced in a loop.
4355 (decode_coding_iso_2022): Abort if there isn't enough place in
4356 charbuf for the composition carryover bytes.
4358 2011-04-21 Eli Zaretskii <eliz@gnu.org>
4360 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
4361 aborting when %lld or %lll format is passed.
4362 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
4363 %llo or %llx format is passed. (Bug#8545)
4365 * window.c (window_scroll_line_based): Use a marker instead of
4366 simple variables to record original value of point. (Bug#7952)
4368 * doprnt.c (doprnt): Fix the case where a multibyte sequence
4369 produced by %s or %c overflows available buffer space. (Bug#8545)
4371 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
4373 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
4374 (SIZE_MAX): Move defn after all includes, as they might #define it.
4376 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4378 * w32.c (init_environment): Warn about defaulting HOME to C:\.
4380 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4382 * keyboard.c (Qdelayed_warnings_hook): Define.
4383 (command_loop_1): Run `delayed-warnings-hook'
4384 if Vdelayed_warnings_list is non-nil.
4385 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
4386 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
4388 2011-04-28 Eli Zaretskii <eliz@gnu.org>
4390 * doprnt.c (doprnt): Don't return value smaller than the buffer
4391 size if the message was truncated. (Bug#8545).
4393 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4395 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
4396 (Fx_window_property): #if-0 the whole functions, not just the bodies.
4398 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
4400 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
4402 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
4404 * makefile.w32-in: Update dependencies.
4406 2011-04-27 Eli Zaretskii <eliz@gnu.org>
4408 Improve `doprnt' and its usage. (Bug#8545)
4409 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
4410 `format_end'. Remove support for %l as a conversion specifier.
4411 Don't use xrealloc. Improve diagnostics when the %l size modifier
4412 is used. Update the commentary.
4414 * eval.c (verror): Simplify calculation of size_t.
4416 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
4419 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
4421 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
4424 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
4426 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
4427 This makes this file independent of the recent pseudovector change.
4429 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
4431 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
4433 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
4434 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
4435 Remove unused local.
4436 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
4438 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
4439 GCC 4.6.0 optimizes based on type-based alias analysis.
4440 For example, if b is of type struct buffer * and v of type struct
4441 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
4442 != &v->size, and therefore "v->size = 1; b->size = 2; return
4443 v->size;" must therefore return 1. This assumption is incorrect
4444 for Emacs, since it type-puns struct Lisp_Vector * with many other
4445 types. To fix this problem, this patch adds a new type struct
4446 vectorlike_header that documents the constraints on layout of vectors
4447 and pseudovectors, and helps optimizing compilers not get fooled
4448 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
4449 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
4450 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
4452 (XSETPVECTYPE): Rewrite in terms of new macro.
4453 (XSETPVECTYPESIZE): New macro, specifying both type and size.
4454 This is a bit clearer, and further avoids the possibility of
4455 undesirable aliasing.
4456 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
4457 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
4458 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
4459 since Lisp_Subr is a special case (no "next" field).
4460 (ASIZE): Now uses header.size rather than size.
4461 All previous uses of XVECTOR (foo)->size replaced to use this macro,
4462 to avoid the hassle of writing XVECTOR (foo)->header.size.
4463 (struct vectorlike_header): New type.
4464 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
4465 object, to help avoid aliasing.
4466 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
4467 (SUBRP): Likewise, since Lisp_Subr is a special case.
4468 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
4469 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
4470 (struct Lisp_Hash_Table): Combine first two members into a single
4471 struct vectorlike_header member. All uses of "size" and "next" members
4472 changed to be "header.size" and "header.next".
4473 * buffer.h (struct buffer): Likewise.
4474 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
4475 * frame.h (struct frame): Likewise.
4476 * process.h (struct Lisp_Process): Likewise.
4477 * termhooks.h (struct terminal): Likewise.
4478 * window.c (struct save_window_data, struct saved_window): Likewise.
4479 * window.h (struct window): Likewise.
4480 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
4481 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
4482 * buffer.c (init_buffer_once): Likewise.
4483 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
4485 * process.c (Fformat_network_address): Use local var for size,
4488 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
4490 Make the Lisp reader and string-to-float more consistent (Bug#8525)
4491 * data.c (atof): Remove decl; no longer used or needed.
4492 (digit_to_number): Move to lread.c.
4493 (Fstring_to_number): Use new string_to_number function, to be
4494 consistent with how the Lisp reader treats infinities and NaNs.
4495 Do not assume that floating-point numbers represent EMACS_INT
4496 without losing information; this is not true on most 64-bit hosts.
4497 Avoid double-rounding errors, by insisting on integers when
4498 parsing non-base-10 numbers, as the documentation specifies.
4499 * lisp.h (string_to_number): New decl, replacing ...
4500 (isfloat_string): Remove.
4501 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
4502 (read1): Do not accept +. and -. as integers; this
4503 appears to have been a coding error. Similarly, do not accept
4504 strings like +-1e0 as floating point numbers. Do not report
4505 overflow for integer overflows unless the base is not 10 which
4506 means we have no simple and reliable way to continue.
4507 Break out the floating-point parsing into a new
4508 function string_to_number, so that Fstring_to_number parses
4509 floating point numbers consistently with the Lisp reader.
4510 (digit_to_number): Move here from data.c. Make it static inline.
4511 (E_CHAR, EXP_INT): Remove, replacing with ...
4512 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
4513 (string_to_number): New function, replacing isfloat_string.
4514 This function checks for valid syntax and produces the resulting
4515 Lisp float number too. Rework it so that string-to-number
4516 no longer mishandles examples like "1.0e+". Use strtoumax,
4517 so that overflow for non-base-10 numbers is reported only when
4518 there's no portable and simple way to convert to floating point.
4520 * textprop.c (set_text_properties_1): Rewrite for clarity,
4521 and to avoid GCC warning about integer overflow.
4523 * intervals.h (struct interval): Use EMACS_INT for members
4524 where EMACS_UINT might cause problems. See
4525 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
4526 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
4527 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
4529 (offset_intervals): Tell GCC not to worry about length overflow
4530 when negating a negative length.
4532 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
4533 (overrun_check_free): Likewise.
4535 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
4536 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
4539 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4540 (gnutls_make_error): Rename local to avoid shadowing.
4541 (gnutls_emacs_global_deinit): ifdef out; not used.
4542 (Fgnutls_boot): Use const for pointer to readonly storage.
4543 Comment out unused local. Fix pointer signedness problems.
4545 * lread.c (openp): Don't stuff size_t into an 'int'.
4546 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
4547 about possible signed overflow.
4549 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4550 (GDK_KEY_g): Don't define if already defined.
4551 (xg_prepare_tooltip): Avoid pointer signedness problem.
4552 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
4554 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
4555 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
4557 * xfns.c (Fx_window_property): Simplify a bit,
4558 to make a bit faster and to avoid GCC 4.6.0 warning.
4559 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
4561 * fns.c (internal_equal): Don't assume size_t fits in int.
4563 * alloc.c (compact_small_strings): Tighten assertion a little.
4565 Replace pEd with more-general pI, and fix some printf arg casts.
4566 * lisp.h (pI): New macro, generalizing old pEd macro to other
4567 conversion specifiers. For example, use "...%"pI"d..." rather
4568 than "...%"pEd"...".
4569 (pEd): Remove. All uses replaced with similar uses of pI.
4570 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
4571 * alloc.c (check_pure_size): Don't overflow by converting size to int.
4572 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
4573 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
4574 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
4575 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
4576 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
4578 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
4579 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
4580 * print.c (safe_debug_print, print_object): Likewise.
4581 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
4583 Use pI instead of if-then-else-abort. Use %p to avoid casts,
4584 avoiding the 0 flag, which is not portable.
4585 * process.c (Fmake_network_process): Use pI to avoid cast.
4586 * region-cache.c (pp_cache): Likewise.
4587 * xdisp.c (decode_mode_spec): Likewise.
4588 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
4589 behavior on 64-bit hosts with printf arg.
4590 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
4591 (x_stop_queuing_selection_requests): Likewise.
4592 (x_get_window_property): Don't truncate byte count to an 'int'
4595 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
4596 here, since it parses constructs like leading '-' and spaces,
4597 which are not wanted; and it overflows with large numbers.
4598 Instead, simply match F[0-9]+, which is what is wanted anyway.
4600 * alloc.c: Remove unportable assumptions about struct layout.
4601 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
4602 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
4603 (allocate_vectorlike, make_pure_vector): Use the new macros,
4604 plus offsetof, to remove unportable assumptions about struct layout.
4605 These assumptions hold on all porting targets that I know of, but
4606 they are not guaranteed, they're easy to remove, and removing them
4607 makes further changes easier.
4609 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
4610 This doesn't fix a bug but makes the code clearer.
4611 (string_overrun_cookie): Now const. Use initializers that
4612 don't formally overflow signed char, to avoid warnings.
4613 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that

5201 * xfaces.c (face_at_string_position):
5202 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
5203 since 0 is always ASCII.

5226 * editfns.c, lisp.h (get_operating_system_release): Remove.

5348 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
5349 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.

5352 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING

5369 * xdisp.c (message_enable_multibyte): Now static.
5371 Declare Lisp_Object Q* variables to be 'static' if not exported.
5372 This makes it easier for human readers (and static analyzers)
5373 to see whether these variables are used from other modules.

5385 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
5387 * lisp.h (DEFINE_FUNC): Make sname 'static'.
5389 Make Emacs functions such as Fatom 'static' by default.
5390 This makes it easier for human readers (and static analyzers)
5391 to see whether these functions can be called from other modules.
5392 DEFUN now defines a static function. To make the function external
5393 so that it can be used in other C modules, use the new macro DEFUE.

5399 Remove decls, since these functions are now static.
5400 (Funintern, Fget_internal_run_time): New decls, since these functions
5401 were already external.

5410 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
5411 Mark functions with DEFUE instead of DEFUN,
5412 if they are used in other modules.

5414 decls for now-static functions.

5446 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
5448 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
5451 2011-04-13 Eli Zaretskii <eliz@gnu.org>
5453 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
5454 when at ZV. (Bug#8487)
5456 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
5458 * charset.c (Fclear_charset_maps): Use xfree instead of free.
5460 * keyboard.c (parse_tool_bar_item): Likewise.
5461 * sound.c (sound_cleanup, alsa_close): Likewise.
5462 * termcap.c (tgetent): Likewise.

5464 * xsettings.c (read_and_apply_settings): Likewise.
5466 * alloc.c (overrun_check_malloc, overrun_check_realloc)
5467 (overrun_check_free): Protoize.
5469 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
5471 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
5472 since callers should never pass a negative size.
5473 Change the signature to match that of plain 'read' and 'write'; see
5474 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
5475 * lisp.h: Update prototypes of emacs_write and emacs_read.
5477 2011-04-11 Eli Zaretskii <eliz@gnu.org>
5479 * xdisp.c (redisplay_window): Don't try to determine the character
5480 position of the scroll margin if the window start point w->startp
5481 is outside the buffer's accessible region. (Bug#8468)
5483 2011-04-10 Eli Zaretskii <eliz@gnu.org>
5485 Fix write-region and its subroutines for buffers > 2GB.
5486 * fileio.c (a_write, e_write): Modify declaration of arguments and
5487 local variables to support buffers larger than 2GB.
5488 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
5490 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
5491 argument, local variables, and return value.
5493 * lisp.h: Update prototypes of emacs_write and emacs_read.
5495 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
5497 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
5499 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
5501 Fix more problems found by GCC 4.6.0's static checks.
5503 * xdisp.c (vmessage): Use a better test for character truncation.
5505 * charset.c (load_charset_map): <, not <=, for optimization,
5506 and to avoid potential problems with integer overflow.
5507 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
5508 * casetab.c (set_identity, shuffle): Likewise.
5509 * editfns.c (Fformat): Likewise.
5510 * syntax.c (skip_chars): Likewise.
5512 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
5513 This also lets GCC 4.6.0 generate slightly better loop code.
5515 * callint.c (Fcall_interactively): <, not <=, for optimization.
5516 (Fcall_interactively): Count the number of arguments produced,
5517 not the number of arguments given. This is simpler and lets GCC
5518 4.6.0 generate slightly better code.
5520 * ftfont.c: Distingish more carefully between FcChar8 and char.
5521 The previous code passed unsigned char * to a functions like
5522 strlen and xstrcasecmp that expect char *, which does not
5523 conform to the C standard.
5524 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
5525 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
5526 char * when the C standard requires it.
5528 * keyboard.c (read_char): Remove unused var.
5530 * eval.c: Port to Windows vsnprintf (Bug#8435).
5532 (SIZE_MAX): Define if the headers do not.
5533 (verror): Do not give up if vsnprintf returns a negative count.
5534 Instead, grow the buffer. This ports to Windows vsnprintf, which
5535 does not conform to C99. Problem reported by Eli Zaretskii.
5536 Also, simplify the allocation scheme, by avoiding the need for
5537 calling realloc, and removing the ALLOCATED variable.
5539 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
5541 Remove invocations of doprnt, as Emacs now uses vsnprintf.
5542 But keep the doprint source code for now, as we might revamp it
5543 and use it again (Bug#8435).
5544 * lisp.h (doprnt): Remove.
5545 * Makefile.in (base_obj): Remove doprnt.o.
5546 * deps.mk (doprnt.o): Remove.
5548 error: Print 32- and 64-bit integers portably (Bug#8435).
5549 Without this change, on typical 64-bit hosts error ("...%d...", N)
5550 was used to print both 32- and 64-bit integers N, which relied on
5552 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):

5562 character to string before calling 'error', since %c now has the
5564 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
5565 overflow when computing char to be passed to 'error'. Do not
5566 pass Lisp_Object to 'error'; pass the integer instead.

5584 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
5585 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
5586 return ssize_t not "int", and use size_t as the buffer length.
5587 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
5588 * gnutls.h: Update declarations.
5589 * process.c (read_process_output): Use ssize_t, to match.
5590 (send_process): Likewise.

5704 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
5705 This avoids several warnings with gcc -Wstrict-overflow.
5706 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
5707 directly, rather than having caller test rule sign. This avoids
5708 some unnecessary tests.
5709 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
5710 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
5711 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

5725 by using the new macro.
5727 * textprop.c (set_text_properties_1): Change while to do-while,
5728 since the condition is always true at first.

5761 * eval.c (funcall_lambda): Rename local to avoid shadowing.
5763 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
5764 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
5765 can always succeed if overflow has undefined behavior.
5767 * search.c (boyer_moore, wordify): Remove vars set but not used.
5768 (wordify): Omit three unnecessary tests.
5770 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
5771 All callers changed. This avoids the need for an unused var.
5773 * casefiddle.c (casify_region): Remove var that is set but not used.
5775 * dired.c (file_name_completion): Remove var that is set but not used.
5777 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
5779 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.

5791 (timer_check_2): Mark vars as initialized.
5793 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
5795 * image.c (lookup_image): Remove var that is set but not used.
5796 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
5798 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
5799 that are set but not used.
5801 * xfns.c (make_invisible_cursor): Don't return garbage
5802 if XCreateBitmapFromData fails (Bug#8410).
5804 * xselect.c (x_get_local_selection, x_handle_property_notify):
5805 Remove vars that are set but not used.
5807 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
5808 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
5810 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
5811 Remove var that is set but not used.

5819 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
5821 * coding.c: Remove vars that are set but not used.
5822 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
5823 All callers changed.
5824 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
5825 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
5826 (decode_coding_charset): Remove vars that are set but not used.
5828 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
5829 that is set but not used.
5831 * print.c (print_object): Remove var that is set but not used.
5833 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
5834 The gnulib version avoids calling malloc in the usual case,
5835 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
5836 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
5837 * filelock.c (current_lock_owner): Likewise.
5838 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
5839 * sysdep.c: Include allocator.h, careadlinkat.h.
5840 (emacs_no_realloc_allocator): New static constant.
5841 (emacs_readlink): New function.
5842 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

5862 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
5863 and thereabouts. All callers changed.
5864 (get_per_char_metric): Remove parameter `f', unused since

5908 * eval.c (Fsetq): Handle lexical vars.
5909 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
5910 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
5911 (FletX, Flet): Obey lexical binding.
5912 (Fcommandp): Handle closures.
5913 (Feval): New `lexical' arg.
5914 (eval_sub): New function extracted from Feval. Use it almost
5915 everywhere where Feval was used. Look up vars in lexical env.
5917 (Ffunctionp): Move from subr.el.
5918 (Ffuncall): Handle closures.
5919 (apply_lambda): Remove `eval_flags'.
5920 (funcall_lambda): Handle closures and new byte-code-functions.
5921 (Fspecial_variable_p): New function.

5933 (exec_byte_code): New function extracted from Fbyte_code to handle new
5934 calling convention for byte-code-functions. Add new byte-codes.
5936 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
5938 * alloc.c (Fmake_symbol): Init new `declared_special' field.

5948 Limit scrolling to 100 screen lines.
5949 (redisplay_window): Even when falling back on "recentering",
5950 position point in the window according to scroll-conservatively,
5951 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
5953 (try_scrolling): When point is above the window, allow searching
5954 as far as scroll_max, or one screenful, to compute vertical
5955 distance from PT to the scroll margin position. This prevents
5956 try_scrolling from unnecessarily failing when
5957 scroll-conservatively is set to a value slightly larger than the
5958 window height. Clean up the case of PT below the margin at bottom
5959 of window: scroll_max can no longer be INT_MAX. When aggressive
5960 scrolling is in use, don't let point enter the opposite scroll
5961 margin as result of the scroll.
5962 (syms_of_xdisp) <scroll-conservatively>: Document the
5963 threshold of 100 lines for never-recentering scrolling.

5972 (redisplay_internal): Remove parameter `preserve_echo_area',
5973 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
5975 * indent.c (Fvertical_motion):
5976 * window.c (window_scroll_pixel_based, Frecenter):
5977 Don't pass `need_y_p' to `move_it_by_lines'.
5979 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
5981 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
5982 steal a few bits to be more compact.

6031 in this function when indexing through an array. This also
6032 works around GCC bug 48267.
6034 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
6036 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
6038 * chartab.c (sub_char_table_ref_and_range): Redo for slight
6039 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
6041 * keyboard.c, keyboard.h (num_input_events): Now size_t.
6042 This avoids undefined behavior on integer overflow, and is a bit
6043 more convenient anyway since it is compared to a size_t variable.
6045 Variadic C functions now count arguments with size_t, not int.
6046 This avoids an unnecessary limitation on 64-bit machines, which
6047 caused (substring ...) to crash on large vectors (Bug#8344).
6048 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
6049 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
6050 All variadic functions and their callers changed accordingly.
6051 (struct gcpro.nvars): Now size_t, not int. All uses changed.
6052 * data.c (arith_driver, float_arith_driver): Likewise.
6053 * editfns.c (general_insert_function): Likewise.
6054 * eval.c (struct backtrace.nargs, interactive_p)
6055 (internal_condition_case_n, run_hook_with_args, apply_lambda)
6056 (funcall_lambda, mark_backtrace): Likewise.
6057 * fns.c (concat): Likewise.
6058 * frame.c (x_set_frame_parameters): Likewise.
6059 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
6060 0 if not found, not -1. All callers changed.
6062 * alloc.c (garbage_collect): Don't assume stack size fits in int.
6063 (stack_copy_size): Now size_t, not int.
6064 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

6084 * keyboard.c (safe_run_hook_funcall): New function.
6085 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
6086 don't set the hook to nil, but remove the offending function instead.
6087 (Qcommand_hook_internal): Remove, unused.
6088 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
6089 Vcommand_hook_internal.
6091 * eval.c (enum run_hooks_condition): Remove.
6092 (funcall_nil, funcall_not): New functions.
6093 (run_hook_with_args): Call each function through a `funcall' argument.
6094 Remove `cond' argument, now redundant.

6107 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
6108 All callers changed.
6110 * w32.c (_wsa_errlist): Use braces for struct initializers.
6112 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
6113 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
6114 All callers changed.
6115 (string_buffer_position): Likewise. Also, make static (it's never
6116 used outside xdisp.c).
6117 (cursor_row_p): Remove parameter `w', unused since
6118 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

6268 * callint.c (Fcall_interactively):
6269 * buffer.c (Fkill_all_local_variables):
6270 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
6272 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
6273 unconditionnaly since it does the check itself.
6275 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
6277 Fix more problems found by GCC 4.5.2's static checks.
6279 * coding.c (encode_coding_raw_text): Avoid unnecessary test
6280 the first time through the loop, since we know p0 < p1 then.
6281 This also avoids a gcc -Wstrict-overflow warning.
6283 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
6284 leading to a memory leak, possible in functions like
6285 load_charset_map_from_file that can allocate an unbounded number
6286 of objects (Bug#8318).
6288 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
6289 that could (at least in theory) be that large.
6291 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
6292 This is less likely to overflow, and avoids undefined behavior if
6293 overflow does occur. All callers changed. Use strtoul to scan
6294 for the unsigned long integer.
6295 (pint2hrstr): Simplify and tune code slightly.
6296 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

6306 * fileio.c (Fcopy_file): Report error if fchown or fchmod
6309 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
6311 * process.c (Fmake_network_process): Use socklen_t, not int,
6312 where POSIX says socklen_t is required in portable programs.
6313 This fixes a porting bug on hosts like 64-bit HP-UX, where
6314 socklen_t is wider than int (Bug#8277).
6315 (Fmake_network_process, server_accept_connection):
6316 (wait_reading_process_output, read_process_output):

6329 Make tparam.h and terminfo.c consistent.
6330 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
6331 Include tparam.h instead, since it declares them.
6332 * cm.h (PC): Remove extern decl; tparam.h now does this.
6333 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
6334 * terminfo.c: Include tparam.h, to check interfaces.
6335 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
6336 (tparam): Adjust signature to match interface in tparam.h;
6337 this removes some undefined behavior. Check that outstring and len
6338 are zero, which they always are with Emacs.
6339 * tparam.h (PC, BC, UP): New extern decls.
6341 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
6342 (xftfont_open): Rename locals to avoid shadowing.
6344 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

6360 (composition_update_it): Mark var as initialized.
6361 (find_automatic_composition): Mark vars as initialized,
6362 with a FIXME (Bug#8290).
6364 character.h: Rename locals to avoid shadowing.
6365 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
6366 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
6367 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
6368 (BUF_DEC_POS): Be more systematic about renaming local temporaries
6371 * textprop.c (property_change_between_p): Remove; unused.
6373 * intervals.c (interval_start_pos): Now static.
6375 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

6378 Rename locals to avoid shadowing.
6380 * sound.c (wav_play, au_play, Fplay_sound_internal):
6381 Fix pointer signedness.
6382 (alsa_choose_format): Remove unused local var.
6383 (wav_play): Initialize a variable to 0, to prevent undefined
6384 behavior (Bug#8278).
6386 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
6388 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
6390 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
6391 clobbering (Bug#8298).
6392 * sysdep.c (sys_subshell): Likewise.
6393 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
6395 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
6396 This should get cleaned up, so that child_setup has the
6397 same signature on all platforms.
6399 * callproc.c (call_process_cleanup): Now static.
6400 (relocate_fd): Rename locals to avoid shadowing.
6402 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
6404 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
6405 not to be necessary, and produces flickering.
6407 2011-03-20 Glenn Morris <rgm@gnu.org>
6409 * config.in: Remove file.
6411 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

6428 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
6430 * makefile.w32-in: Update dependencies.
6432 2011-03-17 Eli Zaretskii <eliz@gnu.org>
6434 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

6458 * unexelf.c (unexec): Name an expression,
6459 to avoid gcc -Wbad-function-cast warning.
6460 Use a different way to cause a compilation error if anyone uses
6461 n rather than nn, a way that does not involve shadowing.
6462 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
6464 * deps.mk (unexalpha.o): Remove; unused.
6466 New file unexec.h, the (simple) interface for unexec (Bug#8267).
6467 * unexec.h: New file.
6468 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):

6569 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6570 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
6571 to use the following functions instead of these macros.
6572 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
6573 EMACS_INT, since callers assume the returned value fits in int.

6586 (regex_compile, re_match_2_internal): Mark locals as initialized.
6587 (RETALLOC_IF): Define only if needed.
6588 (WORDCHAR_P): Likewise. This one is never needed, but is used
6589 only in a comment talking about a compiler bug, so put inside
6590 the #if 0 of that comment.
6591 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
6592 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
6595 * search.c (boyer_moore): Rename locals to avoid shadowing.

6620 gcpro1, gcpro2, etc.
6621 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
6623 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
6624 argument, for consistency with GCPRO2_VAR, etc: it is now the
6625 prefix of the variable, not the variable itself. All uses
6627 * dired.c (directory_files_internal, file_name_completion):
6628 Rename locals to avoid shadowing.
6630 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
6631 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
6632 dired.c's scmp function, had undefined behavior.
6633 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6634 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
6635 * buffer.h: ... to here, because these macros use current_buffer,
6636 and the new implementation with inline functions needs to have
6637 current_buffer in scope now, rather than later when the macros
6639 (downcase, upcase1): New static inline functions.
6640 (DOWNCASE, UPCASE1): Reimplement using these functions.
6641 This avoids undefined behavior in expressions like
6642 DOWNCASE (x) == DOWNCASE (y), which previously suffered
6643 from race conditions in accessing the global variables
6644 case_temp1 and case_temp2.
6645 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
6646 * lisp.h (case_temp1, case_temp2): Remove their decls.
6647 * character.h (ASCII_CHAR_P): Move from here ...
6648 * lisp.h: ... to here, so that the inline functions mentioned
6651 * dired.c (directory_files_internal_unwind): Now static.
6653 * fileio.c (file_name_as_directory, directory_file_name):
6654 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
6656 (file_name_as_directory): Use const pointers when appropriate.
6657 (Fexpand_file_name): Likewise. In particular, newdir might
6658 point at constant storage, so make it a const pointer.

6660 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
6662 (Fset_file_times, Finsert_file_contents, auto_save_error):

6672 so that gcc does not warn that these functions aren't declared.
6674 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
6675 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

6680 (lock_file_1): Rename local to avoid shadowing.
6682 * buffer.c (fix_overlays_before): Mark locals as initialized.
6683 (fix_start_end_in_overlays): Likewise. This function should be
6684 simplified by using pointers-to-pointers, but that's a different
6686 (switch_to_buffer_1): Now static.
6687 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
6688 (report_overlay_modification): Rename locals to avoid shadowing.

6691 Fix pointer signedness issue.
6692 (sys_subshell): Mark local as volatile if checking for lint,
6693 to suppress a gcc -Wclobbered warning that does not seem to be right.
6694 (MAXPATHLEN): Define only if needed.
6696 * process.c (serial_open, serial_configure): Move decls from here ...
6697 * systty.h: ... to here, so that they can be checked.
6699 * fns.c (get_random, seed_random): Move extern decls from here ...
6700 * lisp.h: ... to here, so that they can be checked.
6702 * sysdep.c (reset_io): Now static.
