10 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
11 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14 * term.c (tty_append_glyph): New function.
15 (produce_stretch_glyph): Static function and its prototype deleted.
17 * dispextern.h (produce_stretch_glyph, tty_append_glyph): Add
20 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
22 * image.c (parse_image_spec): Check for nonnegative, not for positive,
23 when checking :margin (Bug#9390).
24 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):

30 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
33 2011-08-27 Eli Zaretskii <eliz@gnu.org>

38 the first character in the line after the newline.
40 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
42 * ccl.c: Improve and simplify overflow checking (Bug#9196).
43 (ccl_driver): Do not generate an out-of-range pointer.

48 Simplify the newly-introduced buffer reallocation code.
50 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
52 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
54 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
56 Integer and memory overflow issues (Bug#9196).
58 * doc.c (get_doc_string): Rework so that
59 get_doc_string_buffer_size is the actual buffer size, rather than
60 being 1 less than the actual buffer size; this makes xpalloc more
63 * image.c (x_allocate_bitmap_record, cache_image):
64 * xselect.c (Fx_register_dnd_atom):
65 Simplify previous changes by using xpalloc.
67 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
68 since either will do and ptrdiff_t is convenient with xpalloc.
70 * charset.c (charset_table_size)
71 (struct charset_sort_data.priority): Now ptrdiff_t.
72 (charset_compare): Don't overflow if priorities differ greatly.
73 (Fsort_charsets): Don't assume list length fits in int.
74 Check for size-calculation overflow when allocating sort data.
75 (syms_of_charset): Allocate an initial charset table that is
76 just under 64 KiB, to avoid problems with glibc malloc and mmap.
78 * cmds.c (internal_self_insert): Check for size-calculation overflow.
80 * composite.h (struct composition.glyph_len): Now int, not unsigned.
81 The actual value is always <= INT_MAX, and leaving it unsigned made
82 overflow checking harder.
84 * dispextern.h (struct glyph_matrix.rows_allocated)
85 (struct face_cache.size): Now ptrdiff_t, for convenience in use
86 with xpalloc. The values are still always <= INT_MAX.

90 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
91 (SAFE_NALLOCA): New macro.
93 * region-cache.c (struct boundary.pos, find_cache_boundary)
94 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
95 (set_cache_region, invalidate_region_cache)
96 (revalidate_region_cache, know_region_cache, region_cache_forward)
97 (region_cache_backward, pp_cache):
98 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
99 so that ptrdiff_t * can be passed to xpalloc.
100 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
101 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

111 * bidi.c (bidi_shelve_header_size): New constant.
112 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
113 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
115 * bidi.c (bidi_cache_shrink):
116 * buffer.c (overlays_at, overlays_in, record_overlay_string)
118 Don't update size of array until after memory allocation succeeds,
119 because xmalloc/xrealloc may not return.
120 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
121 now that we have proper integer overflow checking.
122 (record_overlay_string, overlay_strings): Catch overflows when
123 calculating size of overlay_str_buf.
125 * callproc.c (Fcall_process): Check for size overflow when
126 calculating size of args2.
127 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
128 Normally we prefer signed values, but sticking with ptrdiff_t would
129 require adding more-complicated checks.
131 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
132 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
133 Redo buffer-overflow calculations to avoid integer overflow.
134 Add a FIXME comment where memory seems to be over-allocated.
136 * character.c (Fstring): Check for size-calculation overflow.
138 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
139 unnecessary integer overflow. Check for size overflow.

152 (row_table_size): Now ptrdiff_t, not int.
153 (scrolling_window): Avoid overflow in size calculations.
154 Don't update size until allocation succeeds.

161 (get_doc_string): Check for size calculation overflow.
162 Don't update size until allocation succeeds.
163 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
164 EMACS_INT, where ptrdiff_t will do.
165 (Fsubstitute_command_keys): Check for string overflow.
167 * editfns.c (set_time_zone_rule): Don't assume environment length
169 (message_length): Now ptrdiff_t, not int.
170 (Fmessage_box): Don't update size until allocation succeeds.
171 Don't assume message length fits in int.
172 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
174 * emacs.c (main): Do not reallocate argv, since there is a null at
175 the end that can be overwritten, and this way there's no need to
176 worry about size-calculation overflow.
177 (sort_args): Check for size-calculation overflow.
179 * eval.c (init_eval_once, grow_specpdl): Don't update size until
181 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.

184 (x_set_scroll_bar_width, x_figure_window_size):
185 Check for integer overflow.
186 (x_set_alpha): Do not assume XINT fits in int.
188 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
189 This is for the members text_lines, text_cols, total_lines, total_cols,
190 where the system imposes an 'int' limit.
192 * fringe.c (Fdefine_fringe_bitmap):
193 Don't update size until alloc works.
195 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
196 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
198 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
199 Check for size-calculation overflow.
200 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
201 do, as we prefer signed integers.
202 (id_to_widget.max_size, id_to_widget.used)
203 (xg_store_widget_in_map, xg_remove_widget_from_map)
204 (xg_get_widget_from_map, xg_get_scroll_id_for_window)

206 Use and return ptrdiff_t, not int.
207 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
208 * gtkutil.h: Change prototypes to match the above.
210 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
211 are duplicate now that they've been promoted to lisp.h.
212 (x_allocate_bitmap_record, x_alloc_image_color)
213 (make_image_cache, cache_image, xpm_load):
214 Don't update size until alloc is done.
215 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)

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

289 Check for size calculation overflow.
290 (cache_face): Treat size calculation overflows as if they were
291 memory exhaustion (the usual treatment), rather than aborting.
293 * xfns.c (x_encode_text, x_set_name_internal)
294 (Fx_change_window_property): Use ptrdiff_t, not int, to count
295 sizes, since they can exceed INT_MAX in size. Check for size
296 calculation overflow.
298 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
299 (xg_select): Check for size calculation overflow.
300 Don't update size until alloc done.
302 * xrdb.c (get_environ_db): Don't assume path length fits in int,
303 as sprintf is limited to int lengths.
305 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
306 (X_LONG_MIN): New macros.
307 Use them to make the following changes clearer.
308 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
309 This change doesn't affect the value now, but it may help remind
310 future maintainers not to raise the value too much later.
311 (SELECTION_QUANTUM): Remove, replacing with ...
312 (selection_quantum): ... new function, which avoids overflow.
314 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
315 assumption that selection length fits in 'int'.
316 (x_reply_selection_request, x_handle_selection_request)

318 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)

323 Redo calculations to avoid overflow.
324 (x_reply_selection_request): When sending hint, ceiling it at
325 X_LONG_MAX rather than relying on wraparound overflow to send

328 (lisp_data_to_selection_data, x_property_data_to_lisp):
329 Check for size-calculation overflow.

332 Don't store size until memory allocation succeeds.
333 (x_get_window_property): Plug memory leak on memory exhaustion.
334 Don't double-block input; malloc is safe here. Don't assume 2**34
335 - 4 fits in unsigned long. Add an xassert to check
336 XGetWindowProperty overflow. Be more careful about overflow
337 calculations, and distinguish size from memory overflow better.
338 (receive_incremental_selection): When tracing, don't assume
339 unsigned int is less than INT_MAX.
340 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
341 harmful) conversions of unsigned short to int.

343 in the range -65535 through -1 fit in an X unsigned short.
344 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
345 result parameters unless successful. Rely on cons_to_unsigned
346 to report problems with elements; the old code wasn't right anyway.
347 (x_check_property_data): Check for int overflow; we cannot use
348 a wider type due to X limits.
349 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

380 * image.c (xpm_get_color_table_h):
381 * lisp.h (hash_lookup, hash_put):
382 * minibuf.c (Ftest_completion):
383 Use ptrdiff_t for hash table indexes, not int (which is too
384 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
385 32-bit --with-wide-int hosts).
387 * charset.c (Fdefine_charset_internal): Check for integer overflow.
388 Add a FIXME comment about memory leaks.
389 (syms_of_charset): Don't assume xmalloc returns.

395 Use sanitize_char_width to avoid undefined and/or bad behavior
396 with outlandish widths.
397 * character.h (sanitize_tab_width): Renamed from sanitize_width,
398 now that we have two such functions. All uses changed.
399 (sanitize_char_width): New inline function.

417 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
418 (x_send_scroll_bar_event): Likewise. Check that the size does not
419 exceed limits imposed by XClientMessageEvent, as well as the usual
420 ptrdiff_t and size_t limits.
422 * keyboard.c: Overflow, signedness and related fixes.
423 (make_lispy_movement): Use same integer type in forward decl
424 that is used in the definition.
425 (read_key_sequence, keyremap_step):
426 Change bufsize argument back to int, undoing my 2011-03-30 change.
427 We prefer signed types, and int is wide enough here.
428 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
429 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
430 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
431 length, not size_t. Use ptrdiff_t for index, not int.
432 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
433 possibility of integer overflow.
435 Overflow, signedness and related fixes for images.

461 Prefer int to unsigned where either will do.
462 (tiff_handler): New function, combining the cores of the
463 old tiff_error_handler and tiff_warning_handler. This
464 function is rewritten to use vsnprintf and thereby avoid
465 stack buffer overflows. It uses only the features of vsnprintf
466 that are common to both POSIX and native Microsoft.
467 (tiff_error_handler, tiff_warning_handler): Use it.
468 (tiff_load, gif_load, imagemagick_load_image):
469 Don't assume :index value fits in 'int'.

488 handle_single_display_spec, not just 1 or zero.
489 (handle_single_display_spec): If the display spec is of the form
490 `(space ...)', and specifies display in the text area, return 2
492 (try_cursor_movement): Check for the need to scroll more
493 accurately, and prefer exact match for point under bidi. Don't
494 advance `row' beyond the last row of the window.
496 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
497 into disp_prop; all users changed.
499 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
500 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
501 for the text covered by the display property.
503 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
505 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

518 continuation rows. Fixes unwarranted scroll when point enters a
519 continued line of R2L text within an L2R paragraph, or vice versa.
520 (cursor_row_p): Consider the case of point being equal to
521 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
522 from the end of a short line to the beginning of a continued line
523 of R2L text within L2R paragraph.
524 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

542 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
543 extra slot even if the purpose is char-code-property-table.
545 2011-08-23 Eli Zaretskii <eliz@gnu.org>
547 * xdisp.c (redisplay_window): When computing centering_position,
548 account for the height of the header line. (Bug#8874)
550 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
551 instead of CHAR_TO_BYTE. Fixes a crash when a completion
552 candidate is selected by the mouse, and that candidate has a
553 composed character under the mouse.
555 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
556 coordinates reported by pos-visible-in-window-p for a composed
557 character in column zero.
559 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

567 composed buffer positions.
569 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
571 * image.c (gif_load): Don't assume that each subimage has the same
572 dimensions as the base image. Handle disposal method that is
573 "undefined" by the gif spec (Bug#9335).
575 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
577 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

582 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
583 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
584 from an Org mode buffer to a Speedbar frame.
586 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
587 a composition, take its buffer position from IT->cmp_it.charpos.
588 Fixes cursor positioning at the beginning of a line that begins
589 with a composed character.
591 2011-08-18 Eli Zaretskii <eliz@gnu.org>
593 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
594 character bidirectional type, use STRONG_L instead. Fixes crashes
595 in a buffer produced by `describe-categories'.
597 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
598 members before the level stack, so they would be saved and
599 restored when copying iterator state. Fixes incorrect reordering
600 around TABs covered by display properties.
602 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
604 * process.c (Fnetwork_interface_list): Correctly determine buffer

610 (internal_condition_case_2, internal_condition_case_n):
611 Remove unnecessary aborts (Bug#9081).
613 2011-08-17 Eli Zaretskii <eliz@gnu.org>
615 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
616 has no `load' handler, try opening the file locally. (Bug#9311)

682 ppos_it. Fixes vertical cursor motion when line beginning is
683 covered by an image. (Bug#9296)
685 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
687 * nsterm.h (ns_run_ascript): Declare.

692 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
693 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
694 the event loop. Get status from as_status (Bug#7276).
696 * nsterm.m (sendEvent): If event is NSApplicationDefined and
697 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
698 the event loop (Bug#7276).
700 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
702 * gnutls.c (QCgnutls_bootprop_priority)

724 (Fnetwork_interface_list): Allocate in increments of bytes instead
725 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
726 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
728 (struct ifflag_def): notrailers is smart on OSX.
729 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
730 Get hardware address with getifaddrs if available.
732 2011-08-12 Eli Zaretskii <eliz@gnu.org>
734 * xdisp.c (iterate_out_of_display_property): xassert that
735 IT->position is set to within IT->object's boundaries. Break from
736 the loop as soon as EOB is reached; avoids infloops in redisplay

738 Set IT->current to match the bidi iterator unconditionally.
739 (push_display_prop): Allow GET_FROM_STRING as IT->method on
740 entry. Force push_it to save on the stack the current
741 buffer/string position, to be restored by pop_it. Fix flags in
742 the iterator structure wrt the object coming from a display
743 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
744 properties. (Bug#9284)
746 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
748 * fontset.c (fontset_get_font_group): Add proper type checks.

763 properties and overlays.
765 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
767 * editfns.c (Fset_time_zone_rule): Document relationship with the
770 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to

773 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
775 * composite.c (autocmp_chars): Don't reset point. That is done by
776 restore_point_unwind (Bug#5984).
778 2011-08-07 Juri Linkov <juri@jurta.org>
780 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'

783 2011-08-06 Eli Zaretskii <eliz@gnu.org>
785 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
786 display property strides EOL and includes a newline, as in
787 longlines-mode. (Bug#9254)
788 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
789 word-wrap under bidirectional display. (Bug#9224)
791 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
792 is non-zero, even if the data buffer is NULL. Fixes a crash in
793 vertical-motion with longlines-mode. (Bug#9254)
795 2011-08-05 Eli Zaretskii <eliz@gnu.org>
797 * bidi.c <bidi_cache_total_alloc>: Now static.
798 (bidi_initialize): Initialize bidi_cache_total_alloc.
800 * xdisp.c (display_line): Release buffer allocated for shelved bidi
803 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
804 amount allocated this far in `bidi_cache_total_alloc'.
805 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
806 non-zero, only free the data buffer without restoring the cache
807 contents. All callers changed.
809 * dispextern.h (bidi_unshelve_cache): Update prototype.
811 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
812 (move_it_in_display_line, move_it_to)
813 (move_it_vertically_backward, move_it_by_lines): Replace the call
814 to xfree to an equivalent call to bidi_unshelve_cache.
815 (move_it_in_display_line_to): Fix logic of returning
816 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
818 2011-08-05 Eli Zaretskii <eliz@gnu.org>
820 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
821 came from a string character with a `cursor' property. (Bug#9229)

869 for a display string or property. If found, set DISP_PROP_P
872 * bidi.c (bidi_fetch_char): Accept an additional argument
873 DISP_PROP_P, and pass it to compute_display_string_pos.
874 Only handle text covered by a display string if DISP_PROP_P is returned

897 (reseat_at_next_visible_line_start): Use the bidi iterator state
898 returned by forward_to_next_line_start to restore the state of
899 it->bidi_it after backing up to previous newline. (Bug#9212)
901 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
903 * regex.c (re_comp): Protoize.

962 Without this fix, if a signal arrives just after memory fills up,
963 'malloc' might be invoked reentrantly.
965 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
966 In other words, assume that every image size is allowed, on non-X
967 hosts. This assumption is probably wrong, but it lets Emacs compile.

991 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
992 (bidi_find_other_level_edge):
993 Use ptrdiff_t instead of EMACS_INT where either will do.
994 This works better on 32-bit hosts configured --with-wide-int.
995 (bidi_cache_ensure_space): Check for size-calculation overflow.
996 Use % rather than repeated addition, for better worst-case speed.
997 Don't set bidi_cache_size until after xrealloc returns, because it
999 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
1000 (bidi_cache_ensure_space): Also check that the bidi cache size
1001 does not exceed that of the largest Lisp string or buffer. See Eli
1002 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
1004 * alloc.c (__malloc_size_t): Remove.
1005 All uses replaced by size_t. See Andreas Schwab's note
1006 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
1008 * image.c: Improve checking for integer overflow.
1009 (check_image_size): Assume that f is nonnull, since
1010 it is always nonnull in practice. This is one less thing to
1011 worry about when checking for integer overflow later.
1012 (x_check_image_size): New function, which checks for integer
1013 overflow issues inside X.
1014 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
1015 This removes the need for a memory_full check.
1016 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
1017 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
1018 (xbm_read_bitmap_data): Change locals back to 'int', since
1019 their values must fit in 'int'.
1020 (xpm_load_image, png_load, tiff_load):
1021 Invoke x_create_x_image_and_pixmap earlier,
1022 to avoid much needless work if the image is too large.
1023 (tiff_load): Treat overly large images as if
1024 x_create_x_image_and_pixmap failed, not as malloc failures.
1025 (gs_load): Use x_check_image_size.
1027 * gtkutil.c: Omit integer casts.
1028 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
1029 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
1031 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
1033 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
1034 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
1035 would wrongly return t on a 64-bit host.
1037 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
1038 The plain *_OVERFLOW macros run afoul of GCC bug 49705
1039 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
1040 and therefore cause GCC to emit a bogus diagnostic in some cases.
1042 * image.c: Integer signedness and overflow and related fixes.
1043 This is not an exhaustive set of fixes, but it's time to
1044 record what I've got.
1045 (lookup_pixel_color, check_image_size): Remove redundant decls.
1046 (check_image_size): Don't assume that arbitrary EMACS_INT values
1047 fit in 'int', or that arbitrary 'double' values fit in 'int'.
1048 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
1049 (tiff_load, imagemagick_load_image):
1050 Check for overflow in size calculations.
1051 (x_create_x_image_and_pixmap): Remove unnecessary test for
1052 xmalloc returning NULL; that can't happen.
1053 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
1054 (xpm_color_bucket): Use better integer hashing function.
1055 (xpm_cache_color): Don't possibly over-allocate memory.
1056 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
1057 (gif_memory_source):
1058 Use ptrdiff_t, not int or size_t, to record sizes.
1059 (png_load): Don't assume values greater than 2**31 fit in 'int'.
1060 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
1061 either works, as we prefer signed integers.
1062 (tiff_read_from_memory, tiff_write_from_memory):
1063 Return tsize_t, not size_t, since that's what the TIFF API wants.
1064 (tiff_read_from_memory): Don't fail simply because the read would
1065 go past EOF; instead, return a short read.
1066 (tiff_load): Omit no-longer-needed casts.
1067 (Fimagemagick_types): Don't assume size fits into 'int'.
1069 Improve hashing quality when configured --with-wide-int.
1070 * fns.c (hash_string): New function, taken from sxhash_string.
1071 Do not discard information about ASCII character case; this
1072 discarding is no longer needed.
1073 (sxhash-string): Use it. Change sig to match it. Caller changed.
1074 * lisp.h: Declare it.
1075 * lread.c (hash_string): Remove, since we now use fns.c's version.
1076 The fns.c version returns a wider integer if --with-wide-int is
1077 specified, so this should help the quality of the hashing a bit.
1079 * emacs.c: Integer overflow minor fix.
1080 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
1081 Define only if GNU_LINUX.
1082 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
1084 * dispnew.c: Integer signedness and overflow fixes.
1085 Remove unnecessary forward decls, that were a maintenance hassle.
1086 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
1088 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
1089 (scrolling_window): Use ptrdiff_t, not int, for byte count.
1090 (prepare_desired_row, line_draw_cost):
1091 Use int, not unsigned, where either works.
1092 (save_current_matrix, restore_current_matrix):
1093 Use ptrdiff_t, not size_t, where either works.
1094 (init_display): Check for overflow more accurately, and without
1095 relying on undefined behavior.
1097 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
1098 Remove, replacing with the new symbols in lisp.h. All uses changed.
1099 * fileio.c (make_temp_name):
1100 * filelock.c (lock_file_1, lock_file):
1101 * xdisp.c (message_dolog):
1102 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
1103 Use pMd etc. instead.
1104 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
1105 replacing the pWIDE etc. symbols removed from editfns.c.
1107 * keyboard.h (num_input_events): Now uintmax_t.
1108 This is (very slightly) less likely to mess up due to wraparound.
1111 * buffer.c: Integer signedness fixes.
1112 (alloc_buffer_text, enlarge_buffer_text):
1113 Use ptrdiff_t rather than size_t when either will do, as we prefer
1116 * alloc.c: Integer signedness and overflow fixes.
1117 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
1118 (__malloc_size_t): Default to size_t, not to int.
1119 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
1120 (Fgarbage_collect, mark_object_loop_halt, mark_object):
1121 Prefer ptrdiff_t to size_t when either would do, as we prefer
1123 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
1124 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
1125 Now const. Initialize with values that are in range even if char
1127 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
1128 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
1129 These functions do the right thing with sizes > 2**32.
1130 (check_depth): Now ptrdiff_t, not int.
1131 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
1132 Adjust to new way of storing sizes. Check for size overflow bugs
1134 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
1135 slightly wrong anyway, as it missed one instance of
1136 XMALLOC_OVERRUN_CHECK_OVERHEAD.
1137 (refill_memory_reserve): Omit needless cast to size_t.
1138 (mark_object_loop_halt): Mark as externally visible.
1140 * xselect.c: Integer signedness and overflow fixes.
1141 (Fx_register_dnd_atom, x_handle_dnd_message):
1142 Use ptrdiff_t, not size_t, since we prefer signed.
1143 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
1144 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
1145 x_dnd_atoms_size and x_dnd_atoms_length.
1147 * doprnt.c: Prefer signed to unsigned when either works.
1149 * doprnt.c (doprnt):
1151 * xdisp.c (vmessage):
1152 Use ptrdiff_t, not size_t, when using or implementing doprnt,
1153 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
1154 prefer signed arithmetic to avoid comparison confusion.
1155 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
1156 but is a bit tricky.
1158 Assume freestanding C89 headers, string.h, stdlib.h.
1159 * data.c, doprnt.c, floatfns.c, print.c:
1160 Include float.h unconditionally.
1161 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
1162 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
1163 * regex.c: Likewise for stddef.h, string.h.
1164 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
1165 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
1166 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
1167 (STDC_HEADERS): Remove obsolete defines.
1168 * sysdep.c: Include limits.h unconditionally.
1170 Assume support for memcmp, memcpy, memmove, memset.
1171 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
1172 * regex.c (memcmp, memcpy):
1173 Remove; we assume C89 now.
1175 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
1176 (__malloc_safe_bcopy): Remove; no longer needed.
1178 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
1179 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
1180 well either way, and we prefer signed to unsigned.
1182 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
1184 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
1185 closes the connection while we're reading (bug#9182).
1187 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
1189 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
1190 are specified (Bug#9168).
1192 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
1194 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
1195 Found by GCC static checking and --with-wide-int on a 32-bit host.
1197 2011-07-25 Eli Zaretskii <eliz@gnu.org>
1199 * xdisp.c (compute_display_string_pos): Fix logic of caching
1200 previous display string position. Initialize cached_prev_pos to
1201 -1. Fixes slow-down at the beginning of a buffer.
1203 2011-07-24 Eli Zaretskii <eliz@gnu.org>
1205 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
1206 for attrs[LFACE_FONTSET_INDEX].
1208 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
1210 * xml.c (parse_region): Remove unused local
1211 that was recently introduced.
1213 2011-07-23 Eli Zaretskii <eliz@gnu.org>
1215 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
1216 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
1218 * xdisp.c (move_it_in_display_line_to): Record the best matching
1219 position for TO_CHARPOS while scanning the line, and restore it on
1220 exit if none of the characters scanned was an exact match.
1221 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
1222 when exact match is impossible due to invisible text, and the
1223 lines are truncated.
1225 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
1227 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
1230 2011-07-22 Eli Zaretskii <eliz@gnu.org>
1232 Fix a significant slow-down of cursor motion with C-n, C-p,
1233 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
1234 auto-repeat under bidi redisplay in fontified buffers.
1235 * xdisp.c (compute_stop_pos_backwards): New function.
1236 (next_element_from_buffer): Call compute_stop_pos_backwards to
1237 find a suitable prev_stop when we find ourselves before
1239 (reseat): Don't look for prev_stop, as that could mean a very long
1241 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
1242 <cached_disp_overlay_modiff>: Cache for last found display string
1244 (compute_display_string_pos): Return the cached position if asked
1245 about the same buffer in the same area of character positions, and
1246 the buffer wasn't changed since the time the display string
1247 position was cached.
1249 2011-07-22 Eli Zaretskii <eliz@gnu.org>
1251 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
1252 is an integer, which is important for empty lines. (Bug#9149)
1254 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
1256 * frame.c (Fmodify_frame_parameters): In tty case, update the
1257 default face if necessary (Bug#4238).
1259 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
1261 * editfns.c (Fstring_to_char): No need to explain what a character
1262 is in the docstring (Bug#6576).
1264 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
1266 * xml.c (parse_region): Make sure we always return a tree.
1268 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
1270 * xml.c (parse_region): If a document contains only comments,
1273 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
1275 * xml.c (make_dom): Return comments, too.
1277 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
1280 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
1281 and the surrounding thread.
1282 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
1283 rather than fgets, and retry after EINTR. Otherwise, 'emacs
1284 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
1286 * s/openbsd.h (BROKEN_SIGIO): Define.
1287 * unexelf.c (unexec) [__OpenBSD__]:
1288 Don't update the .mdebug section of the Alpha COFF symbol table.
1290 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
1292 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
1295 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
1297 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
1298 This fixes some race conditions on the permissions of any newly
1301 * alloc.c (valid_pointer_p): Use pipe, not open.
1302 This fixes some permissions issues when debugging.
1304 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
1305 If fchown fails to set both uid and gid, try to set just gid,
1306 as that is sometimes allowed. Adjust the file's mode to eliminate
1307 setuid or setgid bits that are inappropriate if fchown fails.
1309 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
1311 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
1312 to compare Lisp_Objects.
1313 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
1314 global_gnutls_log_level, don't mistake it for a Lisp_Object.
1315 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
1317 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
1319 * lread.c (read_integer): Unread even EOF character.
1320 (read1): Likewise. Properly record start position of symbol.
1322 * lread.c (read1): Read `#:' as empty uninterned symbol if no
1323 symbol character follows.
1325 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
1327 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
1328 This works around a problem with the previous change to Fcopy_file.
1329 Recent glibc declares fchown with __attribute__((warn_unused_result)),
1330 and without this change, GCC might complain about discarding
1331 fchown's return value.
1333 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
1335 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
1337 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
1339 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
1341 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
1343 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
1344 it's used from the C level.
1346 * process.c: Use the same condition for POLL_FOR_INPUT in both
1347 keyboard.c and process.c (bug#1858).
1349 2011-07-09 Lawrence Mitchell <wence@gmx.li>
1351 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
1352 (Fgnutls_boot): Use it.
1354 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
1356 * doc.c (Fsubstitute_command_keys): Revert last change.
1358 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
1360 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
1361 quotes the next character, and doesn't affect other longer
1362 sequences (bug#8935).
1364 * lread.c (syms_of_lread): Clarify that is isn't only
1365 `eval-buffer' and `eval-defun' that's affected by
1366 `lexical-binding' (bug#8460).
1368 2011-07-15 Eli Zaretskii <eliz@gnu.org>
1370 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
1371 bidi redisplay when a line includes both an image and is
1374 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
1376 Fix minor problems found by static checking.
1377 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
1378 (elsz): Now a signed constant, not a size_t var. We prefer signed
1379 types to unsigned, to avoid integer comparison confusion. Without
1380 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
1381 "cannot optimize loop, the loop counter may overflow", a symptom
1383 * indent.c (Fvertical_motion): Mark locals as initialized.
1384 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
1386 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
1388 * search.c (Fre_search_backward): Mention `case-fold-search' in
1389 all the re_search_* functions (bug#8138).
1391 * keyboard.c (Fopen_dribble_file): Document when the file is
1394 2011-07-14 Eli Zaretskii <eliz@gnu.org>
1396 * bidi.c (bidi_dump_cached_states): Fix format of displaying
1399 Support bidi reordering of display and overlay strings.
1400 * xdisp.c (compute_display_string_pos)
1401 (compute_display_string_end): Accept additional argument STRING.
1402 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
1403 (reseat_to_string): Initialize bidi_it->string.s and
1404 bidi_it->string.schars.
1405 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
1406 NULL (avoids a crash in bidi_paragraph_init).
1407 Initialize itb.string.lstring.
1408 (init_iterator): Call bidi_init_it only of a valid
1409 buffer position was specified. Initialize paragraph_embedding to
1411 (reseat_to_string): Initialize the bidi iterator.
1412 (display_string): If we need to ignore text properties of
1413 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
1414 original value of -1 will not work with bidi.)
1415 (compute_display_string_pos): First arg is now struct
1416 `text_pos *'; all callers changed. Support display properties on
1418 (compute_display_string_end): Support display properties on Lisp
1420 (init_iterator, reseat_1, reseat_to_string): Initialize the
1421 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
1422 when iterating on a string not from display properties).
1423 (compute_display_string_pos, compute_display_string_end):
1424 Fix calculation of the object to scan. Fixes an error when using
1426 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
1427 base_level_stop; instead, set base_level_stop to BEGV.
1428 Fixes crashes in vertical-motion.
1429 (next_element_from_buffer): Improve commentary for when
1430 the iterator is before prev_stop.
1431 (init_iterator): Initialize bidi_p from the default value of
1432 bidi-display-reordering, not from buffer-local value. Use the
1433 buffer-local value only if initializing for buffer iteration.
1434 (handle_invisible_prop): Support invisible properties on strings
1435 that are being bidi-reordered.
1436 (set_iterator_to_next): Support bidi reordering of C strings and
1438 (next_element_from_string): Support bidi reordering of Lisp
1440 (handle_stop_backwards): Support Lisp strings as well.
1441 (display_string): Support display of R2L glyph rows.
1442 Use IT_STRING_CHARPOS when displaying from a Lisp string.
1443 (init_iterator): Don't initialize it->bidi_p for strings
1445 (reseat_to_string): Initialize it->bidi_p for strings here.
1446 (next_element_from_string, next_element_from_c_string)
1447 (next_element_from_buffer): Add xassert's for correspondence
1448 between IT's object being iterated and it->bidi_it.string
1450 (face_before_or_after_it_pos): Support bidi iteration.
1451 (next_element_from_c_string): Handle the case of the first string
1452 character that is not the first one in the visual order.
1453 (get_visually_first_element): New function, refactored from common
1454 parts of next_element_from_buffer, next_element_from_string, and
1455 next_element_from_c_string.
1456 (tool_bar_lines_needed, redisplay_tool_bar)
1457 (display_menu_bar): Force left-to-right direction. Add a FIXME
1458 comment for making that be controlled by a user option.

1944 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
1946 Random fixes. E.g., (random) never returned negative values.
1947 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
1948 subseconds part to the entropy, as that's a bit more random.
1949 Prefer signed to unsigned, since the signedness doesn't matter and
1950 in general we prefer signed. When given a limit, use a
1951 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
1952 latter isn't right if USE_2_TAGS_FOR_INTS.
1953 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
1954 not 0..VALMASK. Don't discard "excess" bits that random () returns.

1964 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
1966 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
1967 This is more efficient than Ffile_directory_p and avoids a minor race.
1969 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
1971 * buffer.c (Foverlay_put): Say what the return value is
1974 * fileio.c (barf_or_query_if_file_exists): Check first if the file
1975 is a directory before asking whether to use the file name
1977 (barf_or_query_if_file_exists): Make the "File is a directory"
1978 error be more correct.
1980 * fns.c (Frequire): Remove the mention of the .gz files, since
1981 that's installation-specific, but keep the mention of
1982 `get-load-suffixes'.
1984 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
1986 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

1997 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
1998 Also (re)move comments that are misplaced or no longer relevant.
2000 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>

2097 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
2099 * eval.c (struct backtrace): Simplify and port the data structure.
2100 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
2101 signed bit field, as this assumption is not portable and it makes
2102 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
2103 "char debug_on_exit : 1" as this is not portable either; instead,
2104 use the portable "unsigned int debug_on_exit : 1". Remove unused
2105 member evalargs. Remove obsolete comments about cc bombing out.
2107 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

2269 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
2271 Integer and buffer overflow fixes (Bug#8873).
2273 * print.c (printchar, strout): Check for string overflow.
2274 (PRINTPREPARE, printchar, strout):
2275 Don't set size unless allocation succeeds.
2277 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
2278 for sizes. Check for string overflow more accurately.

2295 (read1): Check for integer overflow in radices, and in
2296 read-circle numbers.
2297 (read_escape): Avoid int overflow.
2298 (Fload, openp, read_buffer_size, read1)
2299 (substitute_object_recurse, read_vector, read_list, map_obarray):

2320 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
2322 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
2323 The following patches are for when GLYPH_DEBUG && !XASSERT.
2324 * dispextern.h (trace_redisplay_p, dump_glyph_string):
2325 * dispnew.c (flush_stdout):
2326 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
2327 Mark as externally visible.
2328 * dispnew.c (check_window_matrix_pointers): Now static.
2329 * dispnew.c (window_to_frame_vpos):
2330 * xfns.c (unwind_create_frame):
2331 * xterm.c (x_check_font): Remove unused local.
2332 * scroll.c (CHECK_BOUNDS):
2333 * xfaces.c (cache_fache): Rename local to avoid shadowing.
2334 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
2335 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
2336 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
2337 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
2339 (debug_method_add): Use va_list and vsprintf rather than relying
2340 on undefined behavior with wrong number of arguments.
2341 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
2342 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
2343 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
2344 since we're not interested in debugging glyphs with old libraries.
2345 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
2346 GCC 4.6.0's static checking.
2348 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
2350 Integer overflow and signedness fixes (Bug#8873).
2351 A few related buffer overrun fixes, too.

2367 (.bitmaps_last, struct x_output.icon_bitmap):
2368 Use ptrdiff_t, not int, for bitmap indexes.
2369 (x_allocate_bitmap_record): Check for size overflow.
2370 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
2372 Use ptrdiff_t, not int, for overlay counts.
2373 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
2374 * editfns.c (overlays_around, get_pos_property):
2375 * textprop.c (get_char_property_and_overlay):
2376 * xdisp.c (next_overlay_change, note_mouse_highlight):
2377 * xfaces.c (face_at_buffer_position):
2378 * buffer.c (OVERLAY_COUNT_MAX): New macro.
2379 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
2380 (Fnext_overlay_change, Fprevious_overlay_change)
2381 (mouse_face_overlay_overlaps, Foverlays_in):
2382 Use ptrdiff_t, not int, for sizes.
2383 (overlays_at, overlays_in): Check for size-calculation overflow.
2385 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
2387 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
2388 (x_session_initialize): Do not assume string length fits in int.
2390 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
2391 This is unlikely, but can occur if DPI is outlandish.
2393 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
2394 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
2396 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
2397 * xrdb.c (magic_file_p, search_magic_path):
2398 Omit last arg SUFFIX; it was always 0. All callers changed.
2399 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
2401 * xfont.c (xfont_match): Avoid need for strlen.
2403 * xfns.c: Don't assume strlen fits in int.
2404 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
2406 * xdisp.c (message_log_check_duplicate): Return intmax_t,
2407 not unsigned long, as we prefer signed integers. All callers changed.
2408 Detect integer overflow in repeat count.
2409 (message_dolog): Don't assume print length fits in 39 bytes.
2410 (display_mode_element): Don't assume strlen fits in int.
2412 * termcap.c: Don't assume sizes fit in int and never overflow.
2413 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
2414 (gobble_line): Check for size-calculation overflow.
2416 * minibuf.c (Fread_buffer):
2417 * lread.c (intern, intern_c_string):
2418 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
2419 Don't assume string length fits in int.
2421 * keyboard.c (parse_tool_bar_item):
2422 * gtkutil.c (style_changed_cb): Avoid need for strlen.
2424 * font.c: Don't assume string length fits in int.
2425 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
2426 Use ptrdiff_t, not int.
2427 (font_intern_prop): Don't assume string length fits in int.
2428 Don't assume integer property fits in fixnum.
2429 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
2431 * filelock.c: Fix some buffer overrun and integer overflow issues.
2432 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
2433 Reformulate so as not to need the command string.
2434 Invoke gzip -cd rather than gunzip, as it's more portable.
2435 (lock_info_type, lock_file_1, lock_file):
2436 Don't assume pid_t and time_t fit in unsigned long.
2437 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
2438 (current_lock_owner): Prefer signed type for sizes.
2439 Use memcpy, not strncpy, where memcpy is what is really wanted.
2440 Don't assume (via atoi) that time_t and pid_t fit in int.
2441 Check for time_t and/or pid_t out of range, e.g., via a network share.
2442 Don't alloca where an auto var works fine.
2444 * fileio.c: Fix some integer overflow issues.
2445 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
2446 Don't assume string length fits in int.
2447 (directory_file_name): Don't assume string length fits in long.
2448 (make_temp_name): Don't assume pid fits in int, or that its print
2449 length is less than 20.
2451 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
2453 * coding.c (make_subsidiaries): Don't assume string length fits in int.
2455 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
2457 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
2458 We prefer signed integers, even for size calculations.
2460 * emacs.c: Don't assume string length fits in 'int'.
2461 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
2462 (main): Don't invoke strlen when not needed.
2464 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
2465 (XD_DEBUG_MESSAGE): Don't waste a byte.
2467 * callproc.c (getenv_internal_1, getenv_internal)
2469 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
2471 * lread.c (invalid_syntax): Omit length argument.
2472 All uses changed. This doesn't fix a bug, but it simplifies the
2473 code away from its former Hollerith-constant appearance, and it's
2474 one less 'int' to worry about when looking at integer-overflow issues.
2475 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
2477 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
2478 This didn't break anything, but it didn't help either.
2479 It's confusing to put a bogus integer in a place where the actual
2480 value does not matter.
2481 (LIST_END_P): Remove unused macro and its bogus comment.
2482 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
2484 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
2485 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
2487 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
2488 We prefer signed types, and the value cannot exceed the EMACS_INT
2489 range anyway (because otherwise the length would not be representable).
2490 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
2491 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
2492 This avoids a GCC warning when WIDE_EMACS_INT.
2494 * indent.c (sane_tab_width): New function.
2495 (current_column, scan_for_column, Findent_to, position_indentation)
2496 (compute_motion): Use it. This is just for clarity.
2497 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
2499 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
2501 * lisp.h (lint_assume): New macro.
2502 * composite.c (composition_gstring_put_cache):
2503 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
2505 * editfns.c, insdel.c:
2506 Omit unnecessary forward decls, to simplify future changes.
2508 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
2510 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
2512 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
2513 Use much-faster test for byte-length change.
2514 Don't assume string byte-length fits in 'int'.
2515 Check that character arg fits in 'int'.
2516 (mapcar1): Declare byte as byte, for clarity.
2518 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
2520 * fns.c (concat): Catch string overflow earlier.
2521 Do not rely on integer wraparound.
2523 * dispextern.h (struct it.overlay_strings_charpos)
2524 (struct it.selective): Now EMACS_INT, not int.
2525 * xdisp.c (forward_to_next_line_start)
2526 (back_to_previous_visible_line_start)
2527 (reseat_at_next_visible_line_start, next_element_from_buffer):
2528 Don't arbitrarily truncate the value of 'selective' to int.
2530 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
2532 * composite.c: Don't truncate sizes to 'int'.
2533 (composition_gstring_p, composition_reseat_it)
2534 (composition_adjust_point): Use EMACS_INT, not int.
2535 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
2536 not EMACS_UINT, for indexes.
2538 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
2540 * buffer.c: Include <verify.h>.
2541 (struct sortvec.priority, struct sortstr.priority):
2542 Now EMACS_INT, not int.
2543 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
2544 (struct sortstr.size, record_overlay_string)
2545 (struct sortstrlist.size, struct sortlist.used):
2546 Don't truncate size to int.
2547 (record_overlay_string): Check for size-calculation overflow.
2548 (init_buffer_once): Check at compile-time, not run-time.
2550 2011-06-22 Jim Meyering <meyering@redhat.com>
2552 Don't leak an XBM-image-sized buffer
2553 * image.c (xbm_load): Free the image buffer after using it.
2555 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
2558 * composite.c (find_automatic_composition): Omit needless 'return 0;'
2559 that Sun C diagnosed.
2560 * fns.c (secure_hash): Fix pointer signedness issue.
2561 * intervals.c (static_offset_intervals): New function.
2562 (offset_intervals): Use it.
2564 2011-06-21 Leo Liu <sdl.web@gmail.com>
2567 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
2570 * fns.c (secure_hash): Rename from crypto_hash_function and change
2571 the first arg to accept symbols.
2572 (Fsecure_hash): New primitive.
2573 (syms_of_fns): New symbols.
2575 2011-06-20 Deniz Dogan <deniz@dogan.se>
2577 * process.c (Fset_process_buffer): Clarify return value in
2580 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
2582 * dispnew.c (add_window_display_history): Use BVAR.
2584 * xdisp.c (debug_method_add): Use BVAR.
2585 (check_window_end, dump_glyph_matrix, dump_glyph)
2586 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
2588 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
2591 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
2592 check till after the cache is created in init_frame_faces.
2594 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
2596 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
2598 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
2600 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
2601 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
2602 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
2604 Improve buffer-overflow checking (Bug#8873).
2605 * fileio.c (Finsert_file_contents):
2606 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
2607 Remove the old (too-loose) buffer overflow checks.
2608 They weren't needed, since make_gap checks for buffer overflow.
2609 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
2610 The old code merely checked for Emacs fixnum overflow, and relied
2611 on undefined (wraparound) behavior. The new code avoids undefined
2612 behavior, and also checks for ptrdiff_t and/or size_t overflow.
2614 * editfns.c (Finsert_char): Don't dump core with very negative counts.
2615 Tune. Don't use wider integers than needed. Don't use alloca.
2616 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
2618 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
2620 * insdel.c, lisp.h (buffer_overflow): New function.
2621 (insert_from_buffer_1, replace_range, replace_range_2):
2622 * insdel.c (make_gap_larger):
2623 * editfns.c (Finsert_char):
2624 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
2626 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
2628 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
2630 Integer overflow and signedness fixes (Bug#8873).
2632 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
2633 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
2635 * fileio.c: Don't assume EMACS_INT fits in off_t.
2636 (emacs_lseek): New static function.
2637 (Finsert_file_contents, Fwrite_region): Use it.
2638 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
2640 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
2642 * fns.c: Don't overflow int when computing a list length.
2643 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
2644 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
2645 truncation on 64-bit hosts. Check for QUIT every
2646 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
2647 faster and is responsive enough.
2648 (Flength): Report an error instead of overflowing an integer.
2649 (Fsafe_length): Return a float if the value is not representable
2650 as a fixnum. This shouldn't happen except in contrived situations.
2651 (Fnthcdr, Fsort): Don't assume list length fits in int.
2652 (Fcopy_sequence): Don't assume vector length fits in int.
2654 * alloc.c: Check that resized vectors' lengths fit in fixnums.
2655 (header_size, word_size): New constants.
2656 (allocate_vectorlike): Don't check size overflow here.
2657 (allocate_vector): Check it here instead, since this is the only
2658 caller of allocate_vectorlike that could cause overflow.
2659 Check that the new vector's length is representable as a fixnum.
2661 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
2662 The previous code was bogus. For example, next_almost_prime (32)
2663 returned 39, which is undesirable as it is a multiple of 3; and
2664 next_almost_prime (24) returned 25, which is a multiple of 5 so
2665 why was the code bothering to check for multiples of 7?
2667 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
2669 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
2671 Variadic C functions now count arguments with ptrdiff_t.
2672 This partly undoes my 2011-03-30 change, which replaced int with size_t.
2673 Back then I didn't know that the Emacs coding style prefers signed int.
2674 Also, in the meantime I found a few more instances where arguments
2675 were being counted with int, which may truncate counts on 64-bit
2676 machines, or EMACS_INT, which may be unnecessarily wide.
2677 * lisp.h (struct Lisp_Subr.function.aMANY)
2678 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
2679 Arg counts are now ptrdiff_t, not size_t.
2680 All variadic functions and their callers changed accordingly.
2681 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
2682 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
2683 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
2684 * callint.c (Fcall_interactively): Check arg count for overflow,
2685 to avoid potential buffer overrun. Use signed char, not 'int',
2686 for 'varies' array, so that we needn't bother to check its size
2687 calculation for overflow.
2688 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
2689 * eval.c (apply_lambda):
2690 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
2691 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
2692 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
2694 * callint.c (Fcall_interactively): Don't use index var as event count.
2696 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
2697 * mem-limits.h (SIZE): Remove; no longer used.
2699 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
2701 Remove unnecessary casts.
2702 * xterm.c (x_term_init):
2703 * xfns.c (x_set_border_pixel):
2704 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
2705 These aren't needed now that we assume ANSI C.
2707 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
2708 It's more likely to cause problems (due to unsigned overflow)
2711 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
2713 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
2715 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
2717 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
2719 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
2721 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
2723 GLYPH_CODE_FACE returns EMACS_INT, not int.
2724 * dispextern.h (merge_faces):
2725 * xfaces.c (merge_faces):
2726 * xdisp.c (get_next_display_element, next_element_from_display_vector):
2727 Don't assume EMACS_INT fits in int.
2729 * character.h (CHAR_VALID_P): Remove unused parameter.
2730 * fontset.c, lisp.h, xdisp.c: All uses changed.
2732 * editfns.c (Ftranslate_region_internal): Omit redundant test.
2734 * fns.c (concat): Minor tuning based on overflow analysis.
2735 This doesn't fix any bugs. Use int to hold character, instead
2736 of constantly refetching from Emacs object. Use XFASTINT, not
2737 XINT, for value known to be a character. Don't bother comparing
2738 a single byte to 0400, as it's always less.
2740 * floatfns.c (Fexpt):
2741 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
2743 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
2746 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
2748 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
2749 Without this fix, on a 64-bit host (aset S 0 4294967386) would
2750 incorrectly succeed when S was a string, because 4294967386 was
2751 truncated before it was used.
2753 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
2754 Otherwise, an out-of-range integer could cause undefined behavior
2757 * composite.c: Use int, not EMACS_INT, for characters.
2758 (fill_gstring_body, composition_compute_stop_pos): Use int, not
2759 EMACS_INT, for values that are known to be in character range.
2760 This doesn't fix any bugs but is the usual style inside Emacs and
2761 may generate better code on 32-bit machines.
2763 Make sure a 64-bit char is never passed to ENCODE_CHAR.
2764 This is for reasons similar to the recent CHAR_STRING fix.
2765 * charset.c (Fencode_char): Check that character arg is actually
2766 a character. Pass an int to ENCODE_CHAR.
2767 * charset.h (ENCODE_CHAR): Verify that the character argument is no
2768 wider than 'int', as a compile-time check to prevent future regressions
2771 * character.c (char_string): Remove unnecessary casts.
2773 Make sure a 64-bit char is never passed to CHAR_STRING.
2774 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
2775 by silently ignoring the top 32 bits, allowing some values
2776 that were far too large to be valid characters.
2777 * character.h: Include <verify.h>.
2778 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
2779 arguments are no wider than unsigned, as a compile-time check
2780 to prevent future regressions in this area.
2782 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
2783 (Fsubst_char_in_region):
2785 * xdisp.c (decode_mode_spec_coding):
2786 Adjust to CHAR_STRING's new requirement.
2787 * editfns.c (Finsert_char, Fsubst_char_in_region):
2788 * fns.c (concat): Check that character args are actually
2789 characters. Without this test, these functions did the wrong
2790 thing with wildly out-of-range values on 64-bit hosts.
2792 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
2793 These casts should not be needed on 32-bit hosts, either.
2794 * keyboard.c (read_char):
2795 * lread.c (Fload): Remove casts to unsigned.
2797 * lisp.h (UNSIGNED_CMP): New macro.
2798 This fixes comparison bugs on 64-bit hosts.
2799 (ASCII_CHAR_P): Use it.
2800 * casefiddle.c (casify_object):
2801 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
2802 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
2803 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
2804 * dispextern.h (FACE_FROM_ID):
2805 * keyboard.c (read_char): Use UNSIGNED_CMP.
2807 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
2808 not to EMACS_INT, to avoid GCC warning.
2810 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
2812 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
2813 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
2814 isn't needed on 32-bit machines.
2816 * buffer.c (Fgenerate_new_buffer_name):
2817 Use EMACS_INT for count, not int.
2818 (advance_to_char_boundary): Return EMACS_INT, not int.
2820 * data.c (Qcompiled_function): Now static.
2822 * window.c (window_body_lines): Now static.
2824 * image.c (gif_load): Rename local to avoid shadowing.
2826 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
2827 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
2828 * alloc.c (make_save_value): Integer argument is now of type

3286 * alloc.c (Fmake_string):
3287 * character.c (string_escape_byte8):
3288 * coding.c (coding_alloc_by_realloc):
3289 * doprnt.c (doprnt):
3290 * editfns.c (Fformat):
3292 Use STRING_BYTES_MAX, not MOST_POSITIVE_FIXNUM,
3293 since they may not be the same number.
3294 * editfns.c (Finsert_char):
3295 * fileio.c (Finsert_file_contents):
3296 Likewise for BUF_BYTES_MAX.
3298 * image.c: Use ptrdiff_t, not int, for sizes.
3299 (slurp_file): Switch from int to ptrdiff_t.
3301 (slurp_file): Check that file size fits in both size_t (for
3302 malloc) and ptrdiff_t (for sanity and safety).
3304 * fileio.c (Fverify_visited_file_modtime): Avoid time overflow
3305 if b->modtime has its maximal value.
3307 * dired.c (Ffile_attributes): Don't assume EMACS_INT has >32 bits.

3316 * charset.c (maybe_unify_char):
3317 * keyboard.c (read_char, reorder_modifiers):
3318 XINT -> XFASTINT, since the integer must be nonnegative.
3319 * ftfont.c (ftfont_spec_pattern):
3320 * keymap.c (access_keymap, silly_event_symbol_error):
3321 XUINT -> XFASTINT, since the integer must be nonnegative.
3322 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
3323 since it makes no difference and we prefer signed.
3324 * keyboard.c (record_char): Use XUINT when all the neighbors do.
3325 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

3336 (LARGE_REQUEST): Remove.
3337 (memory_full): Use SPARE_MEMORY rather than LARGE_REQUEST.
3339 2011-06-06 Martin Rudalics <rudalics@gmx.at>
3341 * lisp.h: Move EXFUNS for Fframe_root_window,
3342 Fframe_first_window and Fset_frame_selected_window to window.h.

3374 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
3376 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
3377 Do not assume that spare memory exists; that assumption is valid
3378 only if SYSTEM_MALLOC.
3379 (LARGE_REQUEST): New macro, so that the issue of large requests
3380 is separated from the issue of spare memory.
3382 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
3384 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

3403 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
3405 2011-06-04 Chong Yidong <cyd@stupidchicken.com>

3419 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
3421 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3423 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
3424 in the current matrix if keep_current_p is non-zero.

3435 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
3436 (bidi_cache_search, bidi_cache_iterator_state)
3437 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)

3441 (bidi_paragraph_init, bidi_resolve_explicit_1)
3442 (bidi_level_of_next_char): Call bidi_fetch_char and
3443 bidi_fetch_char_advance instead of FETCH_CHAR and

3448 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
3449 instead of using explicit *_CHAR codes.
3450 (bidi_resolve_explicit, bidi_resolve_weak):

3452 bidirectional text is supported only in multibyte buffers.
3453 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
3454 it to initialize the frame_window_p member of struct bidi_it.
3455 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
3456 (bidi_resolve_explicit, bidi_resolve_weak)
3457 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
3458 bidi_it->nchars is non-positive.
3459 (bidi_level_of_next_char): Don't try to lookup the cache for the
3460 next/previous character if nothing is cached there yet, or if we
3461 were just reseat()'ed to a new position.

3464 according to the row's direction when priming the loop that looks
3465 for the glyph on which to display cursor.
3466 (single_display_spec_intangible_p): Function deleted.
3467 (display_prop_intangible_p): Reimplement to call
3468 handle_display_spec instead of single_display_spec_intangible_p.
3469 Accept 3 additional arguments needed by handle_display_spec.
3470 This fixes incorrect cursor motion across display property with complex
3471 values: lists, `(when COND...)' forms, etc.
3472 (single_display_spec_string_p): Support property values that are
3473 lists with the argument STRING its top-level element.
3474 (display_prop_string_p): Fix the condition for processing a

3477 last portion of handle_display_prop.
3478 (compute_display_string_pos): Accept additional argument
3479 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
3480 value of a `display' property is a "replacing spec".
3481 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
3482 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
3483 the display property, but just return a value indicating whether
3484 the display property will replace the characters it covers.
3485 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
3486 frame_window_p members of struct bidi_it.
3487 (compute_display_string_pos, compute_display_string_end):
3489 (push_it): Accept second argument POSITION, where pop_it should
3490 jump to continue iteration.
3491 (reseat_1): Initialize bidi_it.disp_pos.
3493 * keyboard.c (adjust_point_for_property): Adjust the call to
3494 display_prop_intangible_p to its new signature.
3496 * dispextern.h (struct bidi_it): New member frame_window_p.
3497 (bidi_init_it): Update prototypes.
3498 (display_prop_intangible_p): Update prototype.
3499 (compute_display_string_pos, compute_display_string_end):
3501 (struct bidi_it): New members nchars and disp_pos. ch_len is now
3504 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
3506 Malloc failure behavior now depends on size of allocation.
3507 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
3508 * lisp.h: Change signatures accordingly.
3509 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
3510 All callers changed. (Bug#8762)
3512 * gnutls.c: Use Emacs's memory allocators.
3513 Without this change, the gnutls library would invoke malloc etc.
3514 directly, which causes problems on non-SYNC_INPUT hosts, and which
3515 runs afoul of improving memory_full behavior. (Bug#8761)
3516 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
3517 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
3518 xfree instead of the default malloc, realloc, free.
3519 (Fgnutls_boot): No need to check for memory allocation failure,
3520 since xmalloc does that for us.
3522 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
3523 * category.c (hash_get_category_set):
3524 * ccl.c (ccl_driver):
3525 * charset.c (Fdefine_charset_internal):

3536 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
3537 (Fsxhash, Fgethash, Fputhash, Fmaphash):
3538 * image.c (make_image, search_image_cache, lookup_image)
3539 (xpm_put_color_table_h):
3540 * lisp.h (struct Lisp_Hash_Table):
3541 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
3542 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
3543 for hashes and hash indexes, instead of 'unsigned' and 'int'.
3544 * alloc.c (allocate_vectorlike):
3545 Check for overflow in vector size calculations.
3546 * ccl.c (ccl_driver):
3547 Check for overflow when converting EMACS_INT to int.
3548 * fns.c, image.c: Remove unnecessary static decls that would otherwise
3549 need to be updated by these changes.
3550 * fns.c (make_hash_table, maybe_resize_hash_table):
3551 Check for integer overflow with large hash tables.
3552 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
3553 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
3554 (SXHASH_REDUCE): New macro.
3555 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
3556 Use it instead of discarding useful hash info with large hash values.
3557 (sxhash_float): New function.
3558 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
3559 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
3560 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
3561 Rewrite to use FIXNUM_BITS, as this simplifies things.
3562 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
3563 Adjust signatures to match updated version of code.
3564 (consing_since_gc): Now EMACS_INT, since a single hash table can
3565 use more than INT_MAX bytes.
3567 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
3569 Make it possible to build with GCC-4.6+ -O2 -flto.
3571 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
3573 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
3575 * minibuf.c (get_minibuffer, read_minibuf_unwind):
3576 Call minibuffer-inactive-mode.
3578 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
3580 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
3581 Update dependencies.
3583 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3585 * data.c (init_data): Remove code for UTS, this system is not
3588 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3590 Don't force ./temacs to start in terminal mode.
3592 * frame.c (make_initial_frame): Initialize faces in all cases, not
3593 only when CANNOT_DUMP is defined.
3594 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
3596 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3598 * dispnew.c (add_window_display_history): Use const for the string
3599 pointer. Remove declaration, not needed.
3601 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3603 Use 'inline', not 'INLINE'.
3604 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
3605 * alloc.c, fontset.c (INLINE): Remove.
3606 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
3607 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
3608 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
3609 * gmalloc.c (register_heapinfo): Use inline unconditionally.
3610 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
3612 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3614 Make it possible to run ./temacs.
3616 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
3617 syms_of_callproc does the same thing. Remove test for
3618 "initialized", do it in the caller.
3619 * emacs.c (main): Avoid calling set_initial_environment when dumping.
3621 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
3623 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
3624 (read_minibuf): Use get_minibuffer.
3625 (syms_of_minibuf): Use DEFSYM.
3626 (Qmetadata): New var.
3627 * data.c (Qbuffer): Don't make it static.
3628 (syms_of_data): Use DEFSYM.
3630 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3632 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
3633 (CCL_CODE_MIN): New macro.
3635 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
3637 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
3639 * eval.c (Qdebug): Now static.
3640 * lisp.h (Qdebug): Remove decl. This reverts a part of the
3641 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
3642 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
3644 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3646 * image.c: Various fixes to ImageMagick code comments.
3647 (Fimagemagick_types): Doc fix.
3649 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
3651 Minor fixes prompted by GCC 4.6.0 warnings.
3653 * xselect.c (converted_selections, conversion_fail_tag): Now static.
3655 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
3656 (x_clipboard_manager_save_all): Move extern decl to ...
3657 * xterm.h: ... here, so that it can be checked for consistency.
3659 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3661 * xselect.c (x_clipboard_manager_save_frame)
3662 (x_clipboard_manager_save_all): New functions.
3663 (Fx_clipboard_manager_save): Lisp function deleted.
3665 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
3666 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
3668 * xterm.h: Update prototype.
3670 2011-05-28 William Xu <william.xwl@gmail.com>
3672 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
3675 2011-05-28 Jim Meyering <meyering@redhat.com>
3677 Avoid a sign-extension bug in crypto_hash_function.
3678 * fns.c (to_uchar): Define.
3679 (crypto_hash_function): Use it to convert some newly-signed
3680 variables to unsigned, to avoid sign-extension bugs. For example,
3681 without this change, (md5 "truc") would evaluate to
3682 45723a2aff78ff4fff7fff1114760e62 rather than the expected
3683 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
3684 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
3686 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3688 Integer overflow fixes.
3690 * dbusbind.c: Serial number integer overflow fixes.
3691 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
3692 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
3693 to hold a serial number that is too large for a fixnum.
3694 (Fdbus_method_return_internal, Fdbus_method_error_internal):
3695 Check for serial numbers out of range. Decode any serial number
3696 that was so large that it became a float. (Bug#8722)
3698 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
3699 (Fdbus_call_method, Fdbus_call_method_asynchronously):
3700 Use XFASTINT rather than XUINT when numbers are nonnegative.
3701 (xd_append_arg, Fdbus_method_return_internal):
3702 (Fdbus_method_error_internal): Likewise. Also, for unsigned
3703 arguments, check that Lisp number is nonnegative, rather than
3704 silently wrapping negative numbers around. (Bug#8722)
3705 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
3708 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
3710 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
3712 ccl: add integer overflow checks
3713 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
3714 (IN_INT_RANGE): New macros.
3715 (ccl_driver): Use them to check for integer overflow when
3716 decoding a CCL program. Many of the new checks are whether XINT (x)
3717 fits in int; it doesn't always, on 64-bit hosts. The new version
3718 doesn't catch all possible integer overflows, but it's an
3719 improvement. (Bug#8719)
3721 * alloc.c (make_event_array): Use XINT, not XUINT.
3722 There's no need for unsigned here.
3724 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
3725 This follows up to the 2011-05-06 change that substituted uintptr_t
3726 for EMACS_INT. This case wasn't caught back then.
3728 Rework Fformat to avoid integer overflow issues.
3729 * editfns.c: Include <float.h> unconditionally, as it's everywhere
3730 now (part of C89). Include <verify.h>.
3731 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
3732 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
3733 (Fformat): Avoid the prepass trying to compute sizes; it was only
3734 approximate and thus did not catch overflow reliably. Instead, walk
3735 through the format just once, formatting and computing sizes as we go,
3736 checking for integer overflow at every step, and allocating a larger
3737 buffer as needed. Keep track separately whether the format is
3738 multibyte. Keep only the most-recently calculated precision, rather
3739 than them all. Record whether each argument has been converted to
3740 string. Use EMACS_INT, not int, for byte and char and arg counts.
3741 Support field widths and precisions larger than INT_MAX. Avoid
3742 sprintf's undefined behavior with conversion specifications such as %#d
3743 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
3744 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
3745 formatting out-of-range floating point numbers with int
3748 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
3750 * data.c: Avoid integer truncation in expressions involving floats.
3751 * data.c: Include <intprops.h>.
3752 (arith_driver): When there's an integer overflow in an expression
3753 involving floating point, convert the integers to floating point
3754 so that the resulting value does not suffer from catastrophic
3755 integer truncation. For example, on a 64-bit host (* 4
3756 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
3757 Do not rely on undefined behavior after integer overflow.
3759 merge count_size_as_multibyte, parse_str_to_multibyte
3760 * character.c, character.h (count_size_as_multibyte):
3761 Rename from parse_str_to_multibyte; all uses changed.
3762 Check for integer overflow.
3763 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
3764 since it's now a duplicate of the other. This is more of
3765 a character than a buffer op, so better that it's in character.c.
3766 * fns.c, print.c: Adjust to above changes.
3768 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
3770 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
3772 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3774 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3775 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
3776 (x_clipboard_manager_save): Now static.
3777 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
3779 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3780 (crypto_hash_function): Now static.
3781 Fix pointer signedness problems. Avoid unnecessary initializations.
3783 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
3785 * termhooks.h (Vselection_alist): Make it terminal-local.
3787 * terminal.c (create_terminal): Initialize it.
3789 * xselect.c: Support for clipboard managers.
3790 (Vselection_alist): Move to termhooks.h as terminal-local var.
3791 (LOCAL_SELECTION): New macro.
3792 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
3793 (symbol_to_x_atom): Remove gratuitous arg.
3794 (x_handle_selection_request, lisp_data_to_selection_data)
3795 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
3796 (x_own_selection, x_get_local_selection, x_convert_selection):
3797 New arg, specifying work frame. Use terminal-local Vselection_alist.
3798 (some_frame_on_display): Delete unused function.
3799 (Fx_own_selection_internal, Fx_get_selection_internal)
3800 (Fx_disown_selection_internal, Fx_selection_owner_p)
3801 (Fx_selection_exists_p): New optional frame arg.
3802 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
3803 (x_handle_selection_clear): Don't treat other terminals with the
3804 same keyboard specially. Use the terminal-local Vselection_alist.
3805 (x_clear_frame_selections): Use Frun_hook_with_args.
3807 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
3809 * xterm.h: Add support for those atoms.
3811 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
3813 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
3814 (converted_selections, conversion_fail_tag): New global variables.
3815 (x_selection_request_lisp_error): Free the above.
3816 (x_get_local_selection): Remove unnecessary code.
3817 (x_reply_selection_request): Args changed; handle arbitrary array
3818 of converted selections stored in converted_selections.
3819 Separate the XChangeProperty and SelectionNotify steps.
3820 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
3821 (x_convert_selection): New function.
3822 (x_handle_selection_event): Simplify.
3823 (x_get_foreign_selection): Don't ignore incoming requests while
3824 waiting for an answer; this will fail when we implement
3825 SAVE_TARGETS, and seems unnecessary anyway.
3826 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
3827 (Vx_sent_selection_functions): Doc fix.
3829 2011-05-26 Leo Liu <sdl.web@gmail.com>
3831 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
3833 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3835 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
3837 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
3838 for fringe update if it has periodic bitmap.
3839 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
3840 and fringe_bitmap_periodic_p.
3842 * fringe.c (get_fringe_bitmap_data): New function.
3843 (draw_fringe_bitmap_1, update_window_fringes): Use it.
3844 (update_window_fringes): Record periodicity of fringe bitmap in glyph
3845 row. Mark glyph row for fringe update if periodicity changed.
3847 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
3848 for fringe update unless it has periodic bitmap.
3850 2011-05-25 Kenichi Handa <handa@m17n.org>
3852 * xdisp.c (get_next_display_element): Set correct it->face_id for
3853 a static composition.
3855 2011-05-24 Leo Liu <sdl.web@gmail.com>
3858 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
3860 * fns.c (crypto_hash_function, Fsha1): New function.
3861 (Fmd5): Use crypto_hash_function.
3862 (syms_of_fns): Add Ssha1.
3864 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3866 * gnutls.c: Remove unused macros.
3867 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
3868 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
3869 Remove macros that are defined and never used.
3870 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
3872 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3874 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
3875 (Fx_get_selection_internal): Minor cleanup.
3876 (Fx_own_selection_internal): Rename arguments for consistency with
3879 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3881 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
3883 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3885 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
3887 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3889 * dispnew.c (scrolling_window): Don't exclude the case that the
3890 last enabled row in the desired matrix touches the bottom boundary.
3892 2011-05-21 Glenn Morris <rgm@gnu.org>
3894 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
3895 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
3896 and add some more files.
3898 2011-05-20 Eli Zaretskii <eliz@gnu.org>
3900 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
3901 report_file_error introduced by the change from 2011-05-07.
3903 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
3905 * systime.h (Time): Define only if emacs is defined.
3906 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
3907 where the include path doesn't have X11/X.h by default. See
3908 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
3910 2011-05-20 Kenichi Handa <handa@m17n.org>
3912 * composite.c (find_automatic_composition): Fix previous change.
3914 2011-05-20 Glenn Morris <rgm@gnu.org>
3916 * lisp.mk: New file, split from Makefile.in.
3917 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
3918 (shortlisp): Remove.
3919 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
3921 2011-05-19 Glenn Morris <rgm@gnu.org>
3923 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
3924 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
3925 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
3926 (lisp): Set the order to that of loadup.el.
3927 (shortlisp): Make it a copy of $lisp.
3928 (SOME_MACHINE_LISP): Remove.
3929 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
3930 Use just $shortlisp, not $SOME_MACHINE_LISP too.
3932 2011-05-18 Kenichi Handa <handa@m17n.org>
3934 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
3935 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
3936 (find_automatic_composition): Mostly rewrite for efficiency.
3938 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
3940 * makefile.w32-in: Update dependencies.
3942 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
3944 * menu.c: Include limits.h (fixes the MS-Windows build broken by
3945 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
3947 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
3949 Fix some integer overflow issues, such as string length overflow.
3951 * insdel.c (count_size_as_multibyte): Check for string overflow.
3953 * character.c (lisp_string_width): Check for string overflow.
3954 Use EMACS_INT, not int, for string indexes and lengths; in
3955 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
3956 the resulting string length overflows an EMACS_INT; instead,
3957 report a string overflow if no precision given. When checking for
3958 precision exhaustion, use a check that cannot possibly have
3959 integer overflow. (Bug#8675)
3960 * character.h (lisp_string_width): Adjust to new signature.
3962 * alloc.c (string_overflow): New function.
3963 (Fmake_string): Use it. This doesn't change behavior, but saves
3964 a few bytes and will simplify future changes.
3965 * character.c (string_escape_byte8): Likewise.
3966 * lisp.h (string_overflow): New decl.
3968 Fixups, following up to the user-interface timestamp change.
3969 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
3970 for UI timestamps, instead of unsigned long.
3971 * msdos.c (mouse_get_pos): Likewise.
3972 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
3973 * w32gui.h (Time): Define by including "systime.h" rather than by
3974 declaring it ourselves. (Bug#8664)
3976 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
3977 * image.c (clear_image_cache): Likewise.
3979 * term.c (term_mouse_position): Don't assume time_t wraparound.
3981 Be more systematic about user-interface timestamps.
3982 Before, the code sometimes used 'Time', sometimes 'unsigned long',
3983 and sometimes 'EMACS_UINT', to represent these timestamps.
3984 This change causes it to use 'Time' uniformly, as that's what X uses.
3985 This makes the code easier to follow, and makes it easier to catch
3986 integer overflow bugs such as Bug#8664.
3987 * frame.c (Fmouse_position, Fmouse_pixel_position):
3988 Use Time, not unsigned long, for user-interface timestamps.
3989 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
3990 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
3991 * keyboard.h (last_event_timestamp): Likewise.
3992 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
3993 * menu.h (xmenu_show): Likewise.
3994 * term.c (term_mouse_position): Likewise.
3995 * termhooks.h (struct input_event.timestamp): Likewise.
3996 (struct terminal.mouse_position_hook): Likewise.
3997 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
3998 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
3999 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
4000 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
4002 * menu.h, termhooks.h: Include "systime.h", for Time.
4004 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
4005 Don't assume that the difference between two unsigned long values
4006 can fit into an integer. At this point, we know button_down_time
4007 <= event->timestamp, so the difference must be nonnegative, so
4008 there's no need to cast the result if double-click-time is
4009 nonnegative, as it should be; check that it's nonnegative, just in
4010 case. This bug is triggered when events are more than 2**31 ms
4011 apart (about 25 days). (Bug#8664)
4013 * xselect.c (last_event_timestamp): Remove duplicate decl.
4014 (x_own_selection): Remove needless cast to unsigned long.
4016 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
4017 that always fit in int. Use a sentinel instead of a counter, to
4018 avoid a temp and to allay GCC's concerns about possible int overflow.
4019 * frame.h (struct frame): Use int for menu_bar_items_used
4020 instead of EMACS_INT, since it always fits in int.
4022 * menu.c (grow_menu_items): Check for int overflow.
4024 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
4026 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
4027 Before, the code was not consistent. These values cannot exceed
4028 2**31 - 1 so there's no need to make them unsigned.
4029 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
4030 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
4031 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
4033 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
4035 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
4036 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
4037 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
4038 presumably because the widths might not match.
4040 * window.c (size_window): Avoid needless test at loop start.
4042 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
4044 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
4046 2011-05-12 Drew Adams <drew.adams@oracle.com>
4048 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
4050 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4052 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
4053 `width' to `bar_area_x' and `bar_area_width', respectively.
4054 (x_scroll_run): Take account of fringe background extension.
4056 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
4057 Rename local vars `left' and `width' to `bar_area_x' and
4058 `bar_area_width', respectively.
4059 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
4060 background extension.
4062 2011-05-10 Jim Meyering <meyering@redhat.com>
4064 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
4066 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
4068 * image.c (Finit_image_library): Return t for built-in image types,
4069 like pbm and xbm. (Bug#8640)
4071 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
4073 * w32menu.c (set_frame_menubar): Fix submenu allocation.
4075 2011-05-07 Eli Zaretskii <eliz@gnu.org>
4077 * w32console.c (Fset_screen_color): Doc fix.
4078 (Fget_screen_color): New function.
4079 (syms_of_ntterm): Defsubr it.
4081 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
4082 unlink the temporary file if Fcall_process didn't create it in the
4084 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
4085 child process will be redirected to a file specified with `:file'.
4086 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
4087 cue to call_process_cleanup not to close that handle.
4089 2011-05-07 Ben Key <bkey76@gmail.com>
4091 * makefile.w32-in: The bootstrap-temacs rule now makes use of
4092 one of two shell specific rules, either bootstrap-temacs-CMD or
4093 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
4094 to the previous implementation of the bootstrap-temacs rule.
4095 The bootstrap-temacs-CMD rule is similar to the previous
4096 implementation of the bootstrap-temacs rule except that it
4097 makes use of the ESC_CFLAGS variable instead of the CFLAGS
4100 These changes, along with some changes to nt/configure.bat,
4101 nt/gmake.defs, and nt/nmake.defs, are required to extend my
4102 earlier fix to add support for --cflags and --ldflags options
4103 that include quotes so that it works whether make uses cmd or
4106 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
4108 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
4109 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
4111 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
4112 a string. Handle both cases.
4113 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
4114 (Fdbus_register_method): Use Qinvalid_function.
4116 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
4118 * makefile.w32-in: Update dependencies.
4119 (LISP_H): Add inttypes.h and stdin.h.
4120 (PROCESS_H): Add unistd.h.
4122 2011-05-06 Eli Zaretskii <eliz@gnu.org>
4124 * lread.c: Include limits.h (fixes the MS-Windows build broken by
4125 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
4127 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
4129 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
4131 * term.c (vfatal): Remove stray call to va_end.
4132 It's not needed and the C Standard doesn't allow it here anyway.
4134 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
4135 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
4137 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
4140 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
4142 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
4144 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
4146 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
4148 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
4150 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
4151 * charset.c (Fdefine_charset_internal): Don't initialize
4152 charset.code_space[15]. The value was garbage, on hosts with
4153 32-bit int (Bug#8600).
4155 * lread.c (read_integer): Be more consistent with string-to-number.
4156 Use string_to_number to do the actual conversion; this avoids
4157 rounding errors and fixes some other screwups. Without this fix,
4158 for example, #x1fffffffffffffff was misread as -2305843009213693952.
4159 (digit_to_number): Move earlier, for benefit of read_integer.
4160 Return -1 if the digit is out of range for the base, -2 if it is
4161 not a digit in any supported base. (Bug#8602)
4163 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
4165 * dispnew.c (scrolling_window): Return 1 if we scrolled,
4166 to match comment at start of function. This also removes a
4167 GCC warning about overflow in a 32+64-bit port.
4169 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
4171 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
4172 Reported by Stefan Monnier in
4173 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
4174 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
4175 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
4177 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
4178 (EMACS_UINTPTR): Likewise, with uintptr_t.
4180 * lisp.h: Prefer 64-bit EMACS_INT if available.
4181 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
4182 on 32-bit hosts that have 64-bit int, so that they can access
4184 However, temporarily disable this change unless the temporary
4185 symbol WIDE_EMACS_INT is defined.
4187 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
4189 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
4190 This removes an assumption that EMACS_INT and long are the same
4191 width as pointers. The assumption is true for Emacs porting targets
4192 now, but we want to make other targets possible.
4193 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
4194 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
4195 In the rest of the code, change types of integers that hold casted
4196 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
4197 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
4198 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
4199 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
4200 No need to cast type when ORing.
4201 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
4202 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
4203 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
4204 assume EMACS_INT is the same width as char *.
4205 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
4206 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
4207 Remove no-longer-needed casts.
4208 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
4209 (xg_tool_bar_help_callback, xg_make_tool_item):
4210 Use EMACS_INTPTR to hold an integer
4211 that will be cast to void *; this can avoid a GCC warning
4212 if EMACS_INT is not the same width as void *.
4213 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
4214 * xdisp.c (display_echo_area_1, resize_mini_window_1):
4215 (current_message_1, set_message_1):
4216 Use a local to convert to proper width without a cast.
4217 * xmenu.c (dialog_selection_callback): Likewise.
4219 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
4220 Also, don't assume VALBITS / RAND_BITS is less than 5,
4221 and don't rely on undefined behavior when shifting a 1 left into
4223 * lisp.h (get_random): Change signature to match.
4225 * lread.c (hash_string): Use size_t, not int, for hash computation.
4226 Normally we prefer signed values; but hashing is special, because
4227 it's better to use unsigned division on hash table sizes so that
4228 the remainder is nonnegative. Also, size_t is the natural width
4229 for hashing into memory. The previous code used 'int', which doesn't
4230 retain enough info to hash well into very large tables.
4231 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
4233 * dbusbind.c: Don't possibly lose pointer info when converting.
4234 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
4235 Use XPNTR rather than XHASH, so that the high-order bits of
4236 the pointer aren't lost when converting through void *.
4238 * eval.c (Fautoload): Don't double-shift a pointer.
4240 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
4242 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
4244 * gnutls.c (DEF_GNUTLS_FN):
4245 * image.c (DEF_IMGLIB_FN): Make function pointers static.
4247 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
4249 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end

4263 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
4264 `gnutls_certificate_set_x509_key_file'.
4266 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
4268 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
4269 Update dependencies.
4271 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4273 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
4274 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
4275 Remove unused parameter `fildes'.
4276 * process.c (read_process_output, send_process): Don't pass it.
4278 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4280 Fix previous change: the library cache is defined in w32.c.
4281 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
4282 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
4284 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4286 Implement dynamic loading of GnuTLS on Windows.

4310 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
4311 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.

4316 * w32.c (QCloaded_from, Vlibrary_cache): Define.
4317 (w32_delayed_load): Move from image.c. When loading a library, record
4318 its filename in the :loaded-from property of the library id.

4320 Initialize and staticpro them.
4321 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
4323 * process.c: Include lisp.h before w32.h, not after.
4324 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
4325 instead of gnutls_record_check_pending.
4327 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
4329 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
4331 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
4332 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
4335 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
4337 * xterm.c (x_set_frame_alpha): Do not set property on anything
4338 else than FRAME_X_OUTER_WINDOW (Bug#8608).
4340 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
4342 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
4344 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
4346 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

4362 Move after wait_for_termination_1.
4364 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
4366 * sysdep.c (interruptible_wait_for_termination): New function
4367 which is like wait_for_termination, but allows keyboard
4370 * callproc.c (Fcall_process): Add (:file "file") as an option for
4372 (Fcall_process_region): Ditto.
4374 2011-04-30 Eli Zaretskii <eliz@gnu.org>
4376 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
4377 rather than `XVECTOR (FOO)->size'.
4379 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
4380 inttypes.h, as a gnulib replacement is used if it not available in
4383 2011-04-21 Eli Zaretskii <eliz@gnu.org>
4385 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
4386 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
4387 of MOST_POSITIVE_FIXNUM. (Bug#8528)
4389 * coding.c (coding_alloc_by_realloc): Error out if destination
4390 will grow beyond MOST_POSITIVE_FIXNUM.
4391 (decode_coding_emacs_mule): Abort if there isn't enough place in
4392 charbuf for the composition carryover bytes. Reserve an extra
4393 space for up to 2 characters produced in a loop.
4394 (decode_coding_iso_2022): Abort if there isn't enough place in
4395 charbuf for the composition carryover bytes.
4397 2011-04-21 Eli Zaretskii <eliz@gnu.org>
4399 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
4400 aborting when %lld or %lll format is passed.
4401 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
4402 %llo or %llx format is passed. (Bug#8545)
4404 * window.c (window_scroll_line_based): Use a marker instead of
4405 simple variables to record original value of point. (Bug#7952)
4407 * doprnt.c (doprnt): Fix the case where a multibyte sequence
4408 produced by %s or %c overflows available buffer space. (Bug#8545)
4410 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
4412 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
4413 (SIZE_MAX): Move defn after all includes, as they might #define it.
4415 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4417 * w32.c (init_environment): Warn about defaulting HOME to C:\.

4427 2011-04-28 Eli Zaretskii <eliz@gnu.org>
4429 * doprnt.c (doprnt): Don't return value smaller than the buffer
4430 size if the message was truncated. (Bug#8545).
4432 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4434 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

4437 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
4439 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
4441 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
4443 * makefile.w32-in: Update dependencies.
4445 2011-04-27 Eli Zaretskii <eliz@gnu.org>
4447 Improve `doprnt' and its usage. (Bug#8545)
4448 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
4449 `format_end'. Remove support for %l as a conversion specifier.
4450 Don't use xrealloc. Improve diagnostics when the %l size modifier
4451 is used. Update the commentary.
4453 * eval.c (verror): Simplify calculation of size_t.
4455 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
4458 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
4460 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
4463 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
4465 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
4466 This makes this file independent of the recent pseudovector change.
4468 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
4470 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
4472 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
4473 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
4474 Remove unused local.
4475 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
4477 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
4478 GCC 4.6.0 optimizes based on type-based alias analysis.
4479 For example, if b is of type struct buffer * and v of type struct
4480 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
4481 != &v->size, and therefore "v->size = 1; b->size = 2; return
4482 v->size;" must therefore return 1. This assumption is incorrect
4483 for Emacs, since it type-puns struct Lisp_Vector * with many other
4484 types. To fix this problem, this patch adds a new type struct
4485 vectorlike_header that documents the constraints on layout of vectors
4486 and pseudovectors, and helps optimizing compilers not get fooled
4487 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
4488 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
4489 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
4491 (XSETPVECTYPE): Rewrite in terms of new macro.
4492 (XSETPVECTYPESIZE): New macro, specifying both type and size.
4493 This is a bit clearer, and further avoids the possibility of
4494 undesirable aliasing.
4495 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
4496 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
4497 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
4498 since Lisp_Subr is a special case (no "next" field).
4499 (ASIZE): Now uses header.size rather than size.
4500 All previous uses of XVECTOR (foo)->size replaced to use this macro,
4501 to avoid the hassle of writing XVECTOR (foo)->header.size.
4502 (struct vectorlike_header): New type.
4503 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
4504 object, to help avoid aliasing.
4505 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
4506 (SUBRP): Likewise, since Lisp_Subr is a special case.
4507 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
4508 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
4509 (struct Lisp_Hash_Table): Combine first two members into a single
4510 struct vectorlike_header member. All uses of "size" and "next" members
4511 changed to be "header.size" and "header.next".
4512 * buffer.h (struct buffer): Likewise.
4513 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
4514 * frame.h (struct frame): Likewise.
4515 * process.h (struct Lisp_Process): Likewise.
4516 * termhooks.h (struct terminal): Likewise.
4517 * window.c (struct save_window_data, struct saved_window): Likewise.
4518 * window.h (struct window): Likewise.
4519 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
4520 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
4521 * buffer.c (init_buffer_once): Likewise.
4522 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
4524 * process.c (Fformat_network_address): Use local var for size,
4527 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
4529 Make the Lisp reader and string-to-float more consistent (Bug#8525)
4530 * data.c (atof): Remove decl; no longer used or needed.
4531 (digit_to_number): Move to lread.c.
4532 (Fstring_to_number): Use new string_to_number function, to be
4533 consistent with how the Lisp reader treats infinities and NaNs.
4534 Do not assume that floating-point numbers represent EMACS_INT
4535 without losing information; this is not true on most 64-bit hosts.
4536 Avoid double-rounding errors, by insisting on integers when
4537 parsing non-base-10 numbers, as the documentation specifies.
4538 * lisp.h (string_to_number): New decl, replacing ...
4539 (isfloat_string): Remove.
4540 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
4541 (read1): Do not accept +. and -. as integers; this
4542 appears to have been a coding error. Similarly, do not accept
4543 strings like +-1e0 as floating point numbers. Do not report
4544 overflow for integer overflows unless the base is not 10 which
4545 means we have no simple and reliable way to continue.
4546 Break out the floating-point parsing into a new
4547 function string_to_number, so that Fstring_to_number parses
4548 floating point numbers consistently with the Lisp reader.
4549 (digit_to_number): Move here from data.c. Make it static inline.
4550 (E_CHAR, EXP_INT): Remove, replacing with ...
4551 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
4552 (string_to_number): New function, replacing isfloat_string.
4553 This function checks for valid syntax and produces the resulting
4554 Lisp float number too. Rework it so that string-to-number
4555 no longer mishandles examples like "1.0e+". Use strtoumax,
4556 so that overflow for non-base-10 numbers is reported only when
4557 there's no portable and simple way to convert to floating point.
4559 * textprop.c (set_text_properties_1): Rewrite for clarity,
4560 and to avoid GCC warning about integer overflow.
4562 * intervals.h (struct interval): Use EMACS_INT for members
4563 where EMACS_UINT might cause problems. See
4564 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
4565 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
4566 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
4568 (offset_intervals): Tell GCC not to worry about length overflow
4569 when negating a negative length.
4571 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
4572 (overrun_check_free): Likewise.
4574 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
4575 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
4578 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4579 (gnutls_make_error): Rename local to avoid shadowing.
4580 (gnutls_emacs_global_deinit): ifdef out; not used.
4581 (Fgnutls_boot): Use const for pointer to readonly storage.
4582 Comment out unused local. Fix pointer signedness problems.
4584 * lread.c (openp): Don't stuff size_t into an 'int'.
4585 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
4586 about possible signed overflow.
4588 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4589 (GDK_KEY_g): Don't define if already defined.
4590 (xg_prepare_tooltip): Avoid pointer signedness problem.
4591 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
4593 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
4594 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
4596 * xfns.c (Fx_window_property): Simplify a bit,
4597 to make a bit faster and to avoid GCC 4.6.0 warning.
4598 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
4600 * fns.c (internal_equal): Don't assume size_t fits in int.
4602 * alloc.c (compact_small_strings): Tighten assertion a little.
4604 Replace pEd with more-general pI, and fix some printf arg casts.
4605 * lisp.h (pI): New macro, generalizing old pEd macro to other
4606 conversion specifiers. For example, use "...%"pI"d..." rather
4607 than "...%"pEd"...".
4608 (pEd): Remove. All uses replaced with similar uses of pI.
4609 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
4610 * alloc.c (check_pure_size): Don't overflow by converting size to int.
4611 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
4612 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
4613 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
4614 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
4615 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
4617 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
4618 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
4619 * print.c (safe_debug_print, print_object): Likewise.
4620 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
4622 Use pI instead of if-then-else-abort. Use %p to avoid casts,
4623 avoiding the 0 flag, which is not portable.
4624 * process.c (Fmake_network_process): Use pI to avoid cast.
4625 * region-cache.c (pp_cache): Likewise.
4626 * xdisp.c (decode_mode_spec): Likewise.

4631 (x_get_window_property): Don't truncate byte count to an 'int'
4634 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
4635 here, since it parses constructs like leading '-' and spaces,
4636 which are not wanted; and it overflows with large numbers.
4637 Instead, simply match F[0-9]+, which is what is wanted anyway.
4639 * alloc.c: Remove unportable assumptions about struct layout.
4640 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.

4643 plus offsetof, to remove unportable assumptions about struct layout.
4644 These assumptions hold on all porting targets that I know of, but
4645 they are not guaranteed, they're easy to remove, and removing them
4646 makes further changes easier.
4648 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
4649 This doesn't fix a bug but makes the code clearer.
4650 (string_overrun_cookie): Now const. Use initializers that
4651 don't formally overflow signed char, to avoid warnings.
4652 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
4653 can cause Emacs to crash when string overrun checking is enabled.
4654 (allocate_buffer): Don't assume sizeof (struct buffer) is a
4655 multiple of sizeof (EMACS_INT); it need not be, if
4656 alignof(EMACS_INT) < sizeof (EMACS_INT).
4657 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

4693 supported by the function. Use SAFE_ALLOCA instead of always
4696 * eval.c (verror): Don't limit the buffer size at size_max-1, that
4697 is one byte too soon. Don't use xrealloc; instead xfree and

4810 about invalid control letter, pass the character's codepoint, not
4811 a pointer to its multibyte form. Improve display of the character
4812 in octal and display also its hex code.
4814 * character.c (char_string): Use %x to display the (unsigned)
4815 codepoint of an invalid character, to avoid displaying a bogus
4818 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
4819 `error', not SYMBOL_NAME itself.
4821 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
4822 character arguments to `error'.
4824 * charset.c (check_iso_charset_parameter): Fix incorrect argument
4825 to `error' in error message about FINAL_CHAR argument. Make sure
4826 FINAL_CHAR is a character, and use %c when it is passed as
4827 argument to `error'.

4891 Define only if needed.
4893 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier

5017 ns_descriptor_to_entity that were caused by using free to
5018 deallocate memory blocks that were allocated by xmalloc (via
5019 xstrdup). This caused Emacs to crash when compiled with
5020 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
5021 --enable-checking=xmallocoverrun). xfree is now used to
5022 deallocate these memory blocks.

5038 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
5039 (emacs_read, emacs_write): Use it.
5040 * process.c (send_process): Adjust to the new signatures of
5041 emacs_write and emacs_gnutls_write. Do not attempt to store

5556 not the number of arguments given. This is simpler and lets GCC
5557 4.6.0 generate slightly better code.
5559 * ftfont.c: Distingish more carefully between FcChar8 and char.
5560 The previous code passed unsigned char * to a functions like
5561 strlen and xstrcasecmp that expect char *, which does not
5562 conform to the C standard.
5563 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
5564 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
5565 char * when the C standard requires it.
5567 * keyboard.c (read_char): Remove unused var.
5569 * eval.c: Port to Windows vsnprintf (Bug#8435).
5571 (SIZE_MAX): Define if the headers do not.
5572 (verror): Do not give up if vsnprintf returns a negative count.
5573 Instead, grow the buffer. This ports to Windows vsnprintf, which
5574 does not conform to C99. Problem reported by Eli Zaretskii.
5575 Also, simplify the allocation scheme, by avoiding the need for
5576 calling realloc, and removing the ALLOCATED variable.
5578 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
5580 Remove invocations of doprnt, as Emacs now uses vsnprintf.
5581 But keep the doprint source code for now, as we might revamp it
5582 and use it again (Bug#8435).
5583 * lisp.h (doprnt): Remove.
5584 * Makefile.in (base_obj): Remove doprnt.o.
5585 * deps.mk (doprnt.o): Remove.
5587 error: Print 32- and 64-bit integers portably (Bug#8435).
5588 Without this change, on typical 64-bit hosts error ("...%d...", N)
5589 was used to print both 32- and 64-bit integers N, which relied on
5591 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
5593 * lisp.h (error, verror): Mark as printf-like functions.
5594 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
5595 Report overflow in size calculations when allocating printf buffer.
5596 Do not truncate output string at its first null byte.
5597 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
5598 Truncate the output at a character boundary, since vsnprintf does not
5600 * charset.c (check_iso_charset_parameter): Convert internal
5601 character to string before calling 'error', since %c now has the
5603 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
5604 overflow when computing char to be passed to 'error'. Do not
5605 pass Lisp_Object to 'error'; pass the integer instead.
5606 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
5607 formatted with plain %d.
5609 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
5611 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
5613 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
5615 * xterm.c (x_catch_errors): Remove duplicate declaration.
5617 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
5619 * xdisp.c, lisp.h (message_nolog): Remove; unused.
5621 2011-04-10 Jim Meyering <meyering@redhat.com>
5623 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
5624 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
5625 return ssize_t not "int", and use size_t as the buffer length.
5626 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
5627 * gnutls.h: Update declarations.
5628 * process.c (read_process_output): Use ssize_t, to match.
5629 (send_process): Likewise.
5631 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
5633 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
5635 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
5637 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
5638 Use unsigned char, to match FcChar8 type definition.
5640 * xterm.c (handle_one_xevent):
5641 * xmenu.c (create_and_show_popup_menu):
5642 * xselect.c (x_decline_selection_request)
5643 (x_reply_selection_request): Avoid type-punned deref of X events.
5645 2011-04-09 Eli Zaretskii <eliz@gnu.org>
5647 Fix some uses of `int' instead of EMACS_INT.

5649 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
5650 (scan_buffer, find_next_newline_no_quit)
5651 (find_before_next_newline, search_command, Freplace_match)
5652 (Fmatch_data): Make some `int' variables be EMACS_INT.
5654 * xdisp.c (display_count_lines): 3rd argument and return value now
5655 EMACS_INT. All callers changed.
5656 (pint2hrstr): Last argument is now EMACS_INT.
5658 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
5659 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
5660 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
5661 (decode_coding_utf_16, decode_coding_emacs_mule)

5663 (decode_coding_ccl, decode_coding_charset)
5664 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
5665 (decode_coding_iso_2022, decode_coding_emacs_mule)
5666 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
5667 <char_offset, last_offset>: Declare EMACS_INT.

5670 (encode_designation_at_bol, encode_coding_iso_2022)
5671 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
5672 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
5674 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
5675 (encode_invocation_designation): Last argument P_NCHARS is now
5677 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
5678 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
5680 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
5683 * ccl.c (Fccl_execute_on_string): Declare some variables
5686 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
5688 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
5690 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>

5694 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
5696 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
5698 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
5700 * keyboard.c (read_char): Call Lisp function help-form-show,
5701 instead of using internal_with_output_to_temp_buffer.
5702 (Qhelp_form_show): New var.
5703 (syms_of_keyboard): Use DEFSYM macro.
5705 * print.c (internal_with_output_to_temp_buffer): Function deleted.
5707 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
5709 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
5711 * process.c (Flist_processes): Remove to Lisp.
5712 (list_processes_1): Delete.
5714 2011-04-06 Eli Zaretskii <eliz@gnu.org>
5716 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
5718 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
5720 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
5722 Fix more problems found by GCC 4.6.0's static checks.
5724 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
5726 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
5728 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
5730 * xdisp.c (vmessage): Mark as a printf-like function.
5732 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
5734 * sound.c (sound_warning): Don't crash if arg contains a printf format.
5736 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
5737 printf-like functions.
5738 (tiff_load): Add casts to remove these marks before passing them
5739 to system-supplied API.
5741 * eval.c (Fsignal): Remove excess argument to 'fatal'.
5743 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
5744 This avoids several warnings with gcc -Wstrict-overflow.
5745 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
5746 directly, rather than having caller test rule sign. This avoids
5747 some unnecessary tests.
5748 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
5749 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
5750 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
5752 * xfont.c (xfont_text_extents): Remove var that was set but not used.
5753 (xfont_open): Avoid unnecessary tests.
5755 * composite.c (composition_gstring_put_cache): Use unsigned integer.
5757 * composite.h, composite.c (composition_gstring_put_cache):
5758 Use EMACS_INT, not int, for length.
5760 * composite.h (COMPOSITION_DECODE_REFS): New macro,
5761 breaking out part of COMPOSITION_DECODE_RULE.
5762 (COMPOSITION_DECODE_RULE): Use it.
5763 * composite.c (get_composition_id): Remove unused local vars,
5764 by using the new macro.
5766 * textprop.c (set_text_properties_1): Change while to do-while,
5767 since the condition is always true at first.
5769 * intervals.c (graft_intervals_into_buffer): Mark var as used.
5770 (interval_deletion_adjustment): Return unsigned value.
5773 * process.c (list_processes_1, create_pty, read_process_output):

5775 (create_pty): Remove unnecessary "volatile"s.
5776 (Fnetwork_interface_info): Avoid possibility of int overflow.

5778 (read_process_output): Simplify nbytes computation if buffered.
5780 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
5782 * syntax.c (scan_words): Remove var that was set but not used.
5783 (update_syntax_table): Use unsigned instead of int.
5785 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

5789 * print.c (print_error_message): Avoid int overflow.
5791 * font.c (font_list_entities): Redo for clarity,
5792 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
5794 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
5795 (font_score): Avoid potential overflow in diff calculation.
5797 * fns.c (substring_both): Remove var that is set but not used.
5798 (sxhash): Redo loop for clarity and to avoid wraparound warning.
5800 * eval.c (funcall_lambda): Rename local to avoid shadowing.
5802 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
5803 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
5804 can always succeed if overflow has undefined behavior.
5806 * search.c (boyer_moore, wordify): Remove vars set but not used.
5807 (wordify): Omit three unnecessary tests.
5809 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
5810 All callers changed. This avoids the need for an unused var.
5812 * casefiddle.c (casify_region): Remove var that is set but not used.
5814 * dired.c (file_name_completion): Remove var that is set but not used.
5816 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
5818 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
5819 (Finsert_file_contents): Remove unnecessary code checking fd.
5821 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
5822 Check for integer overflow on size calculations.
5824 * buffer.c (Fprevious_overlay_change): Remove var that is set
5827 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
5828 Remove vars that are set but not used.
5829 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
5830 (timer_check_2): Mark vars as initialized.
5832 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
5834 * image.c (lookup_image): Remove var that is set but not used.
5835 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
5837 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
5838 that are set but not used.
5840 * xfns.c (make_invisible_cursor): Don't return garbage
5841 if XCreateBitmapFromData fails (Bug#8410).
5843 * xselect.c (x_get_local_selection, x_handle_property_notify):
5844 Remove vars that are set but not used.
5846 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
5847 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
5849 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
5850 Remove var that is set but not used.
5851 (scroll_bar_windows_size): Now size_t, not int.
5852 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
5855 * xfaces.c (realize_named_face): Remove vars that are set but not used.
5856 (map_tty_color) [!defined MSDOS]: Likewise.
5858 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
5860 * coding.c: Remove vars that are set but not used.
5861 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
5862 All callers changed.
5863 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
5864 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
5865 (decode_coding_charset): Remove vars that are set but not used.
5867 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
5868 that is set but not used.
5870 * print.c (print_object): Remove var that is set but not used.
5872 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
5873 The gnulib version avoids calling malloc in the usual case,
5874 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
5875 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
5876 * filelock.c (current_lock_owner): Likewise.
5877 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
5878 * sysdep.c: Include allocator.h, careadlinkat.h.
5879 (emacs_no_realloc_allocator): New static constant.
5880 (emacs_readlink): New function.
5881 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
5882 ../lib/careadlinkat.h.
5884 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
5886 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
5887 first non-nil return value).
5889 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
5891 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
5892 if not defined (Bug#8403).
5894 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
5896 * xdisp.c (display_count_lines): Remove parameter `start',
5897 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5898 (get_char_face_and_encoding): Remove parameter `multibyte_p',
5899 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
5900 (fill_stretch_glyph_string): Remove parameters `row' and `area',
5901 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
5902 and thereabouts. All callers changed.
5903 (get_per_char_metric): Remove parameter `f', unused since
5904 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
5906 2011-04-02 Jim Meyering <meyering@redhat.com>
5908 do not dereference NULL upon failed strdup
5909 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
5910 (ns_get_family): Likewise.
5912 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
5914 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
5916 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
5918 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
5921 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
5923 Add lexical binding.

5930 (Fload): Bind Qlexical_binding.
5931 (readevalloop): Remove `evalfun' arg.
5932 Bind Qinternal_interpreter_environment.
5933 (Feval_buffer): Bind Qlexical_binding.
5934 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
5936 (syms_of_lread): Declare `lexical-binding'.
5938 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
5940 * keyboard.c (eval_dyn): New fun.
5941 (menu_item_eval_property): Use it.
5943 * image.c (parse_image_spec): Use Ffunctionp.
5945 * fns.c (concat, mapcar1): Accept byte-code-functions.
5947 * eval.c (Fsetq): Handle lexical vars.
5948 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
5949 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
5950 (FletX, Flet): Obey lexical binding.
5951 (Fcommandp): Handle closures.
5952 (Feval): New `lexical' arg.
5953 (eval_sub): New function extracted from Feval. Use it almost
5954 everywhere where Feval was used. Look up vars in lexical env.
5956 (Ffunctionp): Move from subr.el.
5957 (Ffuncall): Handle closures.
5958 (apply_lambda): Remove `eval_flags'.
5959 (funcall_lambda): Handle closures and new byte-code-functions.
5960 (Fspecial_variable_p): New function.
5961 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
5962 but without exporting it to Lisp.
5964 * doc.c (Fdocumentation, store_function_docstring):
5965 * data.c (Finteractive_form): Handle closures.
5967 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
5970 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
5972 (exec_byte_code): New function extracted from Fbyte_code to handle new
5973 calling convention for byte-code-functions. Add new byte-codes.
5975 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
5977 * alloc.c (Fmake_symbol): Init new `declared_special' field.
5979 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
5981 * xdisp.c (redisplay_internal): Fix prototype.
5983 2011-03-31 Eli Zaretskii <eliz@gnu.org>
5985 * xdisp.c (SCROLL_LIMIT): New macro.
5986 (try_scrolling): Use it when setting scroll_limit.
5987 Limit scrolling to 100 screen lines.
5988 (redisplay_window): Even when falling back on "recentering",
5989 position point in the window according to scroll-conservatively,
5990 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
5992 (try_scrolling): When point is above the window, allow searching
5993 as far as scroll_max, or one screenful, to compute vertical
5994 distance from PT to the scroll margin position. This prevents
5995 try_scrolling from unnecessarily failing when
5996 scroll-conservatively is set to a value slightly larger than the
5997 window height. Clean up the case of PT below the margin at bottom
5998 of window: scroll_max can no longer be INT_MAX. When aggressive
5999 scrolling is in use, don't let point enter the opposite scroll
6000 margin as result of the scroll.
6001 (syms_of_xdisp) <scroll-conservatively>: Document the
6002 threshold of 100 lines for never-recentering scrolling.
6004 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
6006 * dispextern.h (move_it_by_lines):

6009 (message_log_check_duplicate): Remove parameters `prev_bol' and
6010 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
6011 (redisplay_internal): Remove parameter `preserve_echo_area',
6012 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
6014 * indent.c (Fvertical_motion):
6015 * window.c (window_scroll_pixel_based, Frecenter):
6016 Don't pass `need_y_p' to `move_it_by_lines'.
6018 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
6020 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
6021 steal a few bits to be more compact.
6022 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
6023 Remove unneeded casts.
6025 * bytecode.c (Fbyte_code): CAR and CDR can GC.
6027 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
6029 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
6030 binding" message (bug#7967).

6034 Fix more problems found by GCC 4.6.0's static checks.
6036 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
6037 Remove unused local var.
6039 * editfns.c (Fmessage_box): Remove unused local var.
6041 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
6042 (note_mode_line_or_margin_highlight, note_mouse_highlight):
6043 Omit unused local vars.
6044 * window.c (shrink_windows): Omit unused local var.
6045 * menu.c (digest_single_submenu): Omit unused local var.
6046 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
6047 Omit unused local var.
6049 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
6050 Don't assume string length fits in int.
6051 (keyremap_step, read_key_sequence): Use size_t for sizes.
6052 (read_key_sequence): Don't check last_real_key_start redundantly.
6054 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
6055 instead of alloca (Bug#8344).
6057 * eval.c (Fbacktrace): Don't assume nargs fits in int.
6058 (Fbacktrace_frame): Don't assume nframes fits in int.
6060 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
6062 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
6065 * term.c (produce_glyphless_glyph): Remove unnecessary test.
6067 * cm.c (calccost): Turn while-do into do-while, for clarity.
6069 * keyboard.c (syms_of_keyboard): Use the same style as later
6070 in this function when indexing through an array. This also
6071 works around GCC bug 48267.
6073 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
6075 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
6077 * chartab.c (sub_char_table_ref_and_range): Redo for slight
6078 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
6080 * keyboard.c, keyboard.h (num_input_events): Now size_t.
6081 This avoids undefined behavior on integer overflow, and is a bit
6082 more convenient anyway since it is compared to a size_t variable.
6084 Variadic C functions now count arguments with size_t, not int.
6085 This avoids an unnecessary limitation on 64-bit machines, which
6086 caused (substring ...) to crash on large vectors (Bug#8344).
6087 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
6088 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
6089 All variadic functions and their callers changed accordingly.
6090 (struct gcpro.nvars): Now size_t, not int. All uses changed.
6091 * data.c (arith_driver, float_arith_driver): Likewise.
6092 * editfns.c (general_insert_function): Likewise.
6093 * eval.c (struct backtrace.nargs, interactive_p)
6094 (internal_condition_case_n, run_hook_with_args, apply_lambda)
6095 (funcall_lambda, mark_backtrace): Likewise.
6096 * fns.c (concat): Likewise.
6097 * frame.c (x_set_frame_parameters): Likewise.
6098 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
6099 0 if not found, not -1. All callers changed.
6101 * alloc.c (garbage_collect): Don't assume stack size fits in int.
6102 (stack_copy_size): Now size_t, not int.
6103 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

6109 All callers changed.
6111 * lisp.h (multibyte_char_to_unibyte):
6112 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
6113 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
6114 * character.h (CHAR_TO_BYTE8):
6115 * cmds.c (internal_self_insert):
6116 * editfns.c (general_insert_function):
6117 * keymap.c (push_key_description):
6118 * search.c (Freplace_match):
6119 * xdisp.c (message_dolog, set_message_1): All callers changed.
6121 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
6123 * keyboard.c (safe_run_hook_funcall): New function.
6124 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
6125 don't set the hook to nil, but remove the offending function instead.
6126 (Qcommand_hook_internal): Remove, unused.
6127 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
6128 Vcommand_hook_internal.
6130 * eval.c (enum run_hooks_condition): Remove.
6131 (funcall_nil, funcall_not): New functions.
6132 (run_hook_with_args): Call each function through a `funcall' argument.
6133 Remove `cond' argument, now redundant.

6143 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
6145 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
6146 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
6147 All callers changed.
6149 * w32.c (_wsa_errlist): Use braces for struct initializers.
6151 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
6152 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
6153 All callers changed.
6154 (string_buffer_position): Likewise. Also, make static (it's never
6155 used outside xdisp.c).
6156 (cursor_row_p): Remove parameter `w', unused since
6157 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.
6158 (decode_mode_spec): Remove parameter `precision', introduced during
6159 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
6160 All callers changed.

6296 2011-03-23 Julien Danjou <julien@danjou.info>
6298 * term.c (Fsuspend_tty, Fresume_tty):
6299 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
6300 * window.c (temp_output_buffer_show):
6301 * insdel.c (signal_before_change):
6302 * frame.c (Fhandle_switch_frame):
6303 * fileio.c (Fdo_auto_save):
6304 * emacs.c (Fkill_emacs):
6305 * editfns.c (save_excursion_restore):
6306 * cmds.c (internal_self_insert):
6307 * callint.c (Fcall_interactively):
6308 * buffer.c (Fkill_all_local_variables):
6309 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
6311 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
6312 unconditionnaly since it does the check itself.
6314 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
6316 Fix more problems found by GCC 4.5.2's static checks.
6318 * coding.c (encode_coding_raw_text): Avoid unnecessary test
6319 the first time through the loop, since we know p0 < p1 then.
6320 This also avoids a gcc -Wstrict-overflow warning.
6322 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
6323 leading to a memory leak, possible in functions like
6324 load_charset_map_from_file that can allocate an unbounded number
6325 of objects (Bug#8318).
6327 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
6328 that could (at least in theory) be that large.
6330 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
6331 This is less likely to overflow, and avoids undefined behavior if
6332 overflow does occur. All callers changed. Use strtoul to scan
6333 for the unsigned long integer.
6334 (pint2hrstr): Simplify and tune code slightly.
6335 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
6337 * scroll.c (do_scrolling): Work around GCC bug 48228.
6338 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

6341 This also avoids a warning with gcc -Wstrict-overflow.
6342 (validate_x_resource_name): Simplify count usage.
6343 This also avoids a warning with gcc -Wstrict-overflow.
6345 * fileio.c (Fcopy_file): Report error if fchown or fchmod
6348 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
6350 * process.c (Fmake_network_process): Use socklen_t, not int,
6351 where POSIX says socklen_t is required in portable programs.
6352 This fixes a porting bug on hosts like 64-bit HP-UX, where
6353 socklen_t is wider than int (Bug#8277).
6354 (Fmake_network_process, server_accept_connection):
6355 (wait_reading_process_output, read_process_output):
6358 * process.c: Rename or move locals to avoid shadowing.

6365 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
6366 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
6368 Make tparam.h and terminfo.c consistent.
6369 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
6370 Include tparam.h instead, since it declares them.
6371 * cm.h (PC): Remove extern decl; tparam.h now does this.
6372 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
6373 * terminfo.c: Include tparam.h, to check interfaces.
6374 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
6375 (tparam): Adjust signature to match interface in tparam.h;
6376 this removes some undefined behavior. Check that outstring and len
6377 are zero, which they always are with Emacs.
6378 * tparam.h (PC, BC, UP): New extern decls.
6380 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
6381 (xftfont_open): Rename locals to avoid shadowing.
6383 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
6384 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
6385 (OTF_TAG_SYM): Omit macro if not needed.
6386 (ftfont_list): Remove unused local.
6387 (get_adstyle_property, ftfont_pattern_entity):
6388 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
6389 Rename locals to avoid shadowing.
6391 * xfont.c (xfont_list_family): Mark var as initialized.
6393 * xml.c (make_dom): Now static.
6395 * composite.c (composition_compute_stop_pos): Rename local to

6398 (find_automatic_composition, composition_adjust_point): Likewise.
6399 (composition_update_it): Mark var as initialized.
6400 (find_automatic_composition): Mark vars as initialized,
6401 with a FIXME (Bug#8290).
6403 character.h: Rename locals to avoid shadowing.
6404 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
6405 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
6406 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
6407 (BUF_DEC_POS): Be more systematic about renaming local temporaries
6410 * textprop.c (property_change_between_p): Remove; unused.
6412 * intervals.c (interval_start_pos): Now static.
6414 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
6416 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
6417 Rename locals to avoid shadowing.
6419 * sound.c (wav_play, au_play, Fplay_sound_internal):
6420 Fix pointer signedness.
6421 (alsa_choose_format): Remove unused local var.
6422 (wav_play): Initialize a variable to 0, to prevent undefined
6423 behavior (Bug#8278).
6425 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
6427 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
6429 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
6430 clobbering (Bug#8298).
6431 * sysdep.c (sys_subshell): Likewise.
6432 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
6434 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
6435 This should get cleaned up, so that child_setup has the
6436 same signature on all platforms.
6438 * callproc.c (call_process_cleanup): Now static.
6439 (relocate_fd): Rename locals to avoid shadowing.
6441 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
6443 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
6444 not to be necessary, and produces flickering.
6446 2011-03-20 Glenn Morris <rgm@gnu.org>
6448 * config.in: Remove file.
6450 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
6452 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
6453 are now in src/globals.h.
6454 (syms_of_minibuf): Remove spurious & from previous change.
6456 2011-03-20 Leo <sdl.web@gmail.com>

6464 * xfaces.c (Fx_load_color_file):
6465 Read color file from absolute filename (bug#8250).
6467 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
6469 * makefile.w32-in: Update dependencies.
6471 2011-03-17 Eli Zaretskii <eliz@gnu.org>
6473 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
6475 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>

6485 * s/cygwin.h (PTY_ITERATION): Likewise.
6486 * s/darwin.h (PTY_ITERATION): Likewise.

6531 instead of using an uninitialized var.
6532 (font_sort_entities): Mark var as initialized.

6608 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6609 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
6610 to use the following functions instead of these macros.
6611 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
6612 EMACS_INT, since callers assume the returned value fits in int.

6625 (regex_compile, re_match_2_internal): Mark locals as initialized.
6626 (RETALLOC_IF): Define only if needed.
6627 (WORDCHAR_P): Likewise. This one is never needed, but is used
6628 only in a comment talking about a compiler bug, so put inside
6629 the #if 0 of that comment.
6630 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
6631 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
6634 * search.c (boyer_moore): Rename locals to avoid shadowing.

6659 gcpro1, gcpro2, etc.
6660 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
6662 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
6663 argument, for consistency with GCPRO2_VAR, etc: it is now the
6664 prefix of the variable, not the variable itself. All uses
6666 * dired.c (directory_files_internal, file_name_completion):
6667 Rename locals to avoid shadowing.
6669 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
6670 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
6671 dired.c's scmp function, had undefined behavior.
6672 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6673 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
6674 * buffer.h: ... to here, because these macros use current_buffer,
6675 and the new implementation with inline functions needs to have
6676 current_buffer in scope now, rather than later when the macros
6678 (downcase, upcase1): New static inline functions.
6679 (DOWNCASE, UPCASE1): Reimplement using these functions.
6680 This avoids undefined behavior in expressions like
6681 DOWNCASE (x) == DOWNCASE (y), which previously suffered
6682 from race conditions in accessing the global variables
6683 case_temp1 and case_temp2.
6684 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
6685 * lisp.h (case_temp1, case_temp2): Remove their decls.
6686 * character.h (ASCII_CHAR_P): Move from here ...
6687 * lisp.h: ... to here, so that the inline functions mentioned
6690 * dired.c (directory_files_internal_unwind): Now static.
6692 * fileio.c (file_name_as_directory, directory_file_name):
6693 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
6695 (file_name_as_directory): Use const pointers when appropriate.
6696 (Fexpand_file_name): Likewise. In particular, newdir might
6697 point at constant storage, so make it a const pointer.

6699 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
6701 (Fset_file_times, Finsert_file_contents, auto_save_error):

6711 so that gcc does not warn that these functions aren't declared.
6713 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
6714 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

6719 (lock_file_1): Rename local to avoid shadowing.
6721 * buffer.c (fix_overlays_before): Mark locals as initialized.
6722 (fix_start_end_in_overlays): Likewise. This function should be
6723 simplified by using pointers-to-pointers, but that's a different
6725 (switch_to_buffer_1): Now static.
6726 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
6727 (report_overlay_modification): Rename locals to avoid shadowing.
6729 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
6730 Fix pointer signedness issue.
6731 (sys_subshell): Mark local as volatile if checking for lint,
6732 to suppress a gcc -Wclobbered warning that does not seem to be right.
6733 (MAXPATHLEN): Define only if needed.
6735 * process.c (serial_open, serial_configure): Move decls from here ...
6736 * systty.h: ... to here, so that they can be checked.
6738 * fns.c (get_random, seed_random): Move extern decls from here ...
6739 * lisp.h: ... to here, so that they can be checked.
6741 * sysdep.c (reset_io): Now static.
6742 (wait_for_termination_signal): Remove; unused.
