3 Integer and memory overflow issues (Bug#9196).
5 * doc.c (get_doc_string): Rework so that
6 get_doc_string_buffer_size is the actual buffer size, rather than
7 being 1 less than the actual buffer size; this makes xpalloc more
10 * image.c (x_allocate_bitmap_record, cache_image):
11 * xselect.c (Fx_register_dnd_atom):
12 Simplify previous changes by using xpalloc.
14 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15 since either will do and ptrdiff_t is convenient with xpalloc.
17 * charset.c (charset_table_size)
18 (struct charset_sort_data.priority): Now ptrdiff_t.
19 (charset_compare): Don't overflow if priorities differ greatly.
20 (Fsort_charsets): Don't assume list length fits in int.
21 Check for size-calculation overflow when allocating sort data.
22 (syms_of_charset): Allocate an initial charset table that is
23 just under 64 KiB, to avoid problems with glibc malloc and mmap.
25 * cmds.c (internal_self_insert): Check for size-calculation overflow.
27 * composite.h (struct composition.glyph_len): Now int, not unsigned.
28 The actual value is always <= INT_MAX, and leaving it unsigned made
29 overflow checking harder.
31 * dispextern.h (struct glyph_matrix.rows_allocated)
32 (struct face_cache.size): Now ptrdiff_t, for convenience in use
33 with xpalloc. The values are still always <= INT_MAX.
35 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
37 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
38 (SAFE_NALLOCA): New macro.
40 * region-cache.c (struct boundary.pos, find_cache_boundary)
41 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
42 (set_cache_region, invalidate_region_cache)
43 (revalidate_region_cache, know_region_cache, region_cache_forward)
44 (region_cache_backward, pp_cache):
45 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
46 so that ptrdiff_t * can be passed to xpalloc.
47 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
48 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
49 (pp_cache): Don't assume cache_len fits in int.
50 * region-cache.h: Adjust extern decls to match.
52 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
53 EMACS_INT, since either will do, for xpalloc.
55 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.

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

92 Integer and memory overflow fixes for display code.
93 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.

101 Don't update size until allocation succeeds.
102 * fns.c (concat): Check for overflow in size calculations.
103 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
104 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
105 (NEXT_ALMOST_PRIME_LIMIT): New constant.
107 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
108 (get_doc_string): Check for size calculation overflow.
109 Don't update size until allocation succeeds.
110 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
111 EMACS_INT, where ptrdiff_t will do.
112 (Fsubstitute_command_keys): Check for string overflow.
114 * editfns.c (set_time_zone_rule): Don't assume environment length
116 (message_length): Now ptrdiff_t, not int.
117 (Fmessage_box): Don't update size until allocation succeeds.
118 Don't assume message length fits in int.
119 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
121 * emacs.c (main): Do not reallocate argv, since there is a null at
122 the end that can be overwritten, and this way there's no need to
123 worry about size-calculation overflow.
124 (sort_args): Check for size-calculation overflow.
126 * eval.c (init_eval_once, grow_specpdl): Don't update size until
128 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
130 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
131 (x_set_scroll_bar_width, x_figure_window_size):
132 Check for integer overflow.
133 (x_set_alpha): Do not assume XINT fits in int.
135 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
136 This is for the members text_lines, text_cols, total_lines, total_cols,
137 where the system imposes an 'int' limit.
139 * fringe.c (Fdefine_fringe_bitmap):
140 Don't update size until alloc works.
142 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
143 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
145 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
146 Check for size-calculation overflow.
147 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
148 do, as we prefer signed integers.
149 (id_to_widget.max_size, id_to_widget.used)
150 (xg_store_widget_in_map, xg_remove_widget_from_map)
151 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
152 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
153 Use and return ptrdiff_t, not int.
154 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
155 * gtkutil.h: Change prototypes to match the above.
157 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
158 are duplicate now that they've been promoted to lisp.h.
159 (x_allocate_bitmap_record, x_alloc_image_color)
160 (make_image_cache, cache_image, xpm_load):
161 Don't update size until alloc is done.
162 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
164 Check for size calculation overflow.
165 (ct_colors_allocated_max): New constant.
166 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid

171 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
172 Use ptrdiff_t, not int, to count maps.

196 * region-cache.c (move_cache_gap): Check for size calculation overflow.
198 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
199 overflow. Don't bother calling xmalloc when xrealloc will do.
201 * search.c (Freplace_match): Check for size calculation overflow.
202 (Fset_match_data): Don't assume list lengths fit in 'int'.
204 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
205 for command line length. Do not attempt to address one before the
206 beginning of an array, as that's not portable.
208 * term.c (max_frame_lines): Remove; unused.
209 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
211 (encode_terminal_code, calculate_costs): Check for size
212 calculation overflow.

236 Check for size calculation overflow.
237 (cache_face): Treat size calculation overflows as if they were
238 memory exhaustion (the usual treatment), rather than aborting.
240 * xfns.c (x_encode_text, x_set_name_internal)
241 (Fx_change_window_property): Use ptrdiff_t, not int, to count
242 sizes, since they can exceed INT_MAX in size. Check for size
243 calculation overflow.
245 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
246 (xg_select): Check for size calculation overflow.
247 Don't update size until alloc done.
249 * xrdb.c (get_environ_db): Don't assume path length fits in int,
250 as sprintf is limited to int lengths.
252 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
253 (X_LONG_MIN): New macros.
254 Use them to make the following changes clearer.
255 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
256 This change doesn't affect the value now, but it may help remind
257 future maintainers not to raise the value too much later.
258 (SELECTION_QUANTUM): Remove, replacing with ...
259 (selection_quantum): ... new function, which avoids overflow.
261 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
262 assumption that selection length fits in 'int'.
263 (x_reply_selection_request, x_handle_selection_request)
264 (x_get_window_property, receive_incremental_selection)
265 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
266 (lisp_data_to_selection_data, clean_local_selection_data):

269 (receive_incremental_selection, x_property_data_to_lisp):
270 Redo calculations to avoid overflow.
271 (x_reply_selection_request): When sending hint, ceiling it at
272 X_LONG_MAX rather than relying on wraparound overflow to send
274 (x_get_window_property, receive_incremental_selection)
275 (lisp_data_to_selection_data, x_property_data_to_lisp):
276 Check for size-calculation overflow.

278 (lisp_data_to_selection_data, Fx_register_dnd_atom):
279 Don't store size until memory allocation succeeds.
280 (x_get_window_property): Plug memory leak on memory exhaustion.
281 Don't double-block input; malloc is safe here. Don't assume 2**34
282 - 4 fits in unsigned long. Add an xassert to check
283 XGetWindowProperty overflow. Be more careful about overflow
284 calculations, and distinguish size from memory overflow better.
285 (receive_incremental_selection): When tracing, don't assume
286 unsigned int is less than INT_MAX.
287 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
288 harmful) conversions of unsigned short to int.
289 (lisp_data_to_selection_data): Don't assume that integers
290 in the range -65535 through -1 fit in an X unsigned short.
291 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
292 result parameters unless successful. Rely on cons_to_unsigned
293 to report problems with elements; the old code wasn't right anyway.
294 (x_check_property_data): Check for int overflow; we cannot use
295 a wider type due to X limits.
296 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

327 * image.c (xpm_get_color_table_h):
328 * lisp.h (hash_lookup, hash_put):
329 * minibuf.c (Ftest_completion):
330 Use ptrdiff_t for hash table indexes, not int (which is too
331 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
332 32-bit --with-wide-int hosts).
334 * charset.c (Fdefine_charset_internal): Check for integer overflow.
335 Add a FIXME comment about memory leaks.
336 (syms_of_charset): Don't assume xmalloc returns.

340 * character.h (CHAR_WIDTH):
341 * indent.c (MULTIBYTE_BYTES_WIDTH):
342 Use sanitize_char_width to avoid undefined and/or bad behavior
343 with outlandish widths.
344 * character.h (sanitize_tab_width): Renamed from sanitize_width,
345 now that we have two such functions. All uses changed.
346 (sanitize_char_width): New inline function.
348 Don't assume that tab-width fits in int.

363 * xterm.c: don't go over XClientMessageEvent limit
364 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
365 (x_send_scroll_bar_event): Likewise. Check that the size does not
366 exceed limits imposed by XClientMessageEvent, as well as the usual
367 ptrdiff_t and size_t limits.
369 * keyboard.c: Overflow, signedness and related fixes.
370 (make_lispy_movement): Use same integer type in forward decl
371 that is used in the definition.
372 (read_key_sequence, keyremap_step):
373 Change bufsize argument back to int, undoing my 2011-03-30 change.
374 We prefer signed types, and int is wide enough here.
375 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
376 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
377 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
378 length, not size_t. Use ptrdiff_t for index, not int.
379 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
380 possibility of integer overflow.
382 Overflow, signedness and related fixes for images.

391 * nsmenu.m (update_frame_tool_bar):
392 * xdisp.c (calc_pixel_width_or_height):
393 * xfns.c (image_cache_refcount):

398 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
399 Omit unnecessary casts to int.

401 when the callers expect that.
402 (image_ascent): Redo ascent calculation to avoid int overflow.
403 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
404 (lookup_image): Remove unnecessary tests.
405 (xbm_image_p): Locals are now of int, not EMACS_INT,
406 since parse_image_check makes sure they fit into int.
407 (png_load, gif_load, svg_load_image):
408 Prefer int to unsigned where either will do.
409 (tiff_handler): New function, combining the cores of the
410 old tiff_error_handler and tiff_warning_handler. This
411 function is rewritten to use vsnprintf and thereby avoid
412 stack buffer overflows. It uses only the features of vsnprintf
413 that are common to both POSIX and native Microsoft.
414 (tiff_error_handler, tiff_warning_handler): Use it.
415 (tiff_load, gif_load, imagemagick_load_image):
416 Don't assume :index value fits in 'int'.
417 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
418 (imagemagick_load_image): Check that crop parameters fit into
419 the integer types that MagickCropImage accepts. Don't assume
420 Vimagemagick_render_type has a nonnegative value. Don't assume
421 size_t fits in 'long'.
422 (gs_load): Use printmax_t to print the widest integers possible.
423 Check for integer overflow when computing image height and width.
425 2011-08-19 Eli Zaretskii <eliz@gnu.org>
427 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
428 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
429 from an Org mode buffer to a Speedbar frame.
431 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
432 a composition, take its buffer position from IT->cmp_it.charpos.
433 Fixes cursor positioning at the beginning of a line that begins
434 with a composed character.
436 2011-08-18 Eli Zaretskii <eliz@gnu.org>
438 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
439 character bidirectional type, use STRONG_L instead. Fixes crashes
440 in a buffer produced by `describe-categories'.
442 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
443 members before the level stack, so they would be saved and
444 restored when copying iterator state. Fixes incorrect reordering
445 around TABs covered by display properties.
447 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
449 * process.c (Fnetwork_interface_list): Correctly determine buffer

455 (internal_condition_case_2, internal_condition_case_n): Remove
456 unnecessary aborts (Bug#9081).
458 2011-08-17 Eli Zaretskii <eliz@gnu.org>
460 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
461 has no `load' handler, try opening the file locally. (Bug#9311)
463 2011-08-16 Ken Brown <kbrown@cornell.edu>
465 * gmalloc.c: Expand comment.
467 2011-08-16 Eli Zaretskii <eliz@gnu.org>
469 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
470 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
472 2011-08-16 Ken Brown <kbrown@cornell.edu>

481 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
483 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
485 [CYGWIN] (special_realloc): New function.
486 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
487 requests to realloc storage in the static heap.
489 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
491 * bidi.c (bidi_initialize): Remove unused local.
493 2011-08-15 Eli Zaretskii <eliz@gnu.org>
495 * biditype.h: File removed.
497 * bidimirror.h: File removed.
499 * deps.mk (bidi.o): Remove biditype.h and
502 * makefile.w32-in ($(BLD)/bidi.$(O)): Remove biditype.h and
505 * dispextern.h: Fix a typo in the comment to bidi_type_t.
507 * chartab.c: Improve commentary for the uniprop_table API.
509 * bidi.c (bidi_paragraph_init): Support zero value of
510 bidi_ignore_explicit_marks_for_paragraph_level.
511 (bidi_initialize): Use uniprop_table instead of including
512 biditype.h and bidimirror.h.
514 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
515 coordinates of the iterator when restoring from ppos_it.
518 2011-08-14 Kenichi Handa <handa@m17n.org>
520 * process.c (create_process): Call setup_process_coding_systems
521 after the pid of the process is set to -1 (Bug#8162).
523 2011-08-14 Eli Zaretskii <eliz@gnu.org>
525 * xdisp.c (move_it_in_display_line_to): Don't invoke
526 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
527 ppos_it. Fixes vertical cursor motion when line beginning is
528 covered by an image. (Bug#9296)
530 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
532 * nsterm.h (ns_run_ascript): Declare.
533 (NSAPP_DATA2_RUNASSCRIPT): Define.
535 * nsfns.m (as_script, as_result, as_status): New static variables.
536 (ns_run_ascript): New function.
537 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
538 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
539 the event loop. Get status from as_status (Bug#7276).
541 * nsterm.m (sendEvent): If event is NSApplicationDefined and
542 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
543 the event loop (Bug#7276).
545 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
547 * gnutls.c (QCgnutls_bootprop_priority)
548 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
549 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
550 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
551 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
552 (QCgnutls_bootprop_verify_hostname_error)
553 (QCgnutls_bootprop_callbacks_verify): Rename from
554 Qgnutls_bootprop_..., all uses changed.
556 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
559 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
561 * xfaces.c (Qframe_set_background_mode): Now static.
562 * dispextern.h (Qframe_set_background_mode): Remove decl.
564 * process.c (Fnetwork_interface_info): Declare local only if needed.
566 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
568 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
569 (Fnetwork_interface_list): Allocate in increments of bytes instead
570 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
571 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
573 (struct ifflag_def): notrailers is smart on OSX.
574 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
575 Get hardware address with getifaddrs if available.
577 2011-08-12 Eli Zaretskii <eliz@gnu.org>
579 * xdisp.c (iterate_out_of_display_property): xassert that
580 IT->position is set to within IT->object's boundaries. Break from
581 the loop as soon as EOB is reached; avoids infloops in redisplay
582 when IT->position is set up wrongly due to some bug. Set
583 IT->current to match the bidi iterator unconditionally.
584 (push_display_prop): Allow GET_FROM_STRING as IT->method on
585 entry. Force push_it to save on the stack the current
586 buffer/string position, to be restored by pop_it. Fix flags in
587 the iterator structure wrt the object coming from a display
588 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
589 properties. (Bug#9284)
591 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
593 * fontset.c (fontset_get_font_group): Add proper type checks.

598 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
599 and LC_VERSION_MIN_MACOSX.
600 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
601 (dump_it) [LC_FUNCTION_STARTS]: Use it.
603 2011-08-08 Eli Zaretskii <eliz@gnu.org>
605 * xdisp.c (forward_to_next_line_start): Allow to use the
606 no-display-properties-and-no-overlays under bidi display. Set
607 disp_pos in the bidi iterator to avoid searches for display
608 properties and overlays.
610 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
612 * editfns.c (Fset_time_zone_rule): Document relationship with the
615 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
616 the font entity extracted from the cache (Bug#8109).
618 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
620 * composite.c (autocmp_chars): Don't reset point. That is done by
621 restore_point_unwind (Bug#5984).
623 2011-08-07 Juri Linkov <juri@jurta.org>
625 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
626 to show the arg `TIME' instead of `TIMEVAL'.
628 2011-08-06 Eli Zaretskii <eliz@gnu.org>
630 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
631 display property strides EOL and includes a newline, as in
632 longlines-mode. (Bug#9254)
633 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
634 word-wrap under bidirectional display. (Bug#9224)
636 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
637 is non-zero, even if the data buffer is NULL. Fixes a crash in
638 vertical-motion with longlines-mode. (Bug#9254)
640 2011-08-05 Eli Zaretskii <eliz@gnu.org>
642 * bidi.c <bidi_cache_total_alloc>: Now static.
643 (bidi_initialize): Initialize bidi_cache_total_alloc.
645 *xdisp.c (display_line): Release buffer allocated for shelved bidi
648 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
649 amount allocated this far in `bidi_cache_total_alloc'.
650 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
651 non-zero, only free the data buffer without restoring the cache
652 contents. All callers changed.
654 * dispextern.h (bidi_unshelve_cache): Update prototype.
656 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
657 (move_it_in_display_line, move_it_to)
658 (move_it_vertically_backward, move_it_by_lines): Replace the call
659 to xfree to an equivalent call to bidi_unshelve_cache.
660 (move_it_in_display_line_to): Fix logic of returning
661 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
663 2011-08-05 Eli Zaretskii <eliz@gnu.org>
665 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
666 came from a string character with a `cursor' property. (Bug#9229)
668 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
670 * Makefile.in (LIB_PTHREAD): New variable.
671 (LIBES): Add LIB_PTHREAD (Bug#9216).
673 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
674 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
676 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
678 * regex.c (re_iswctype): Remove some redundant boolean
681 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
683 * xterm.c (x_find_topmost_parent): New function.
684 (x_set_frame_alpha): Find topmost parent window with
685 x_find_topmost_parent and set the property there also (bug#9181).
686 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
688 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
690 * callproc.c (Fcall_process): Avoid vfork clobbering
691 the local vars buffer, coding_systems, current_dir.
693 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
695 * keymap.c (Fmake_composed_keymap): Move to subr.el.
697 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
699 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
700 so that it is not optimized away.
702 * xdisp.c (compute_display_string_pos): Remove unused local.
704 2011-08-02 Eli Zaretskii <eliz@gnu.org>
706 Fix slow cursor motion and scrolling in large buffers with
707 selective display, like Org Mode buffers. (Bug#9218)
709 * dispextern.h (struct bidi_it): New member disp_prop_p.
711 * xdisp.c: Remove one-slot cache of display string positions.
712 (compute_display_string_pos): Accept an additional argument
713 DISP_PROP_P; callers changed. Scan at most 5K characters forward
714 for a display string or property. If found, set DISP_PROP_P
717 * bidi.c (bidi_fetch_char): Accept an additional argument
718 DISP_PROP_P, and pass it to compute_display_string_pos.
719 Only handle text covered by a display string if DISP_PROP_P is returned
720 non-zero. All callers of bidi_fetch_char changed.
722 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
724 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
726 2010-12-03 Don March <don@ohspite.net>
728 * keymap.c (Fdefine_key): Fix non-prefix key error message when
729 last character M-[char] is translated to ESC [char] (bug#7541).
731 2011-08-02 Kenichi Handa <handa@m17n.org>
733 * lisp.h (uniprop_table): Extern it.
735 * chartab.c (uniprop_table): Make it non-static.
737 2011-08-01 Eli Zaretskii <eliz@gnu.org>
739 * xdisp.c (forward_to_next_line_start): Accept additional argument
740 BIDI_IT_PREV, and store into it the state of the bidi iterator had
742 (reseat_at_next_visible_line_start): Use the bidi iterator state
743 returned by forward_to_next_line_start to restore the state of
744 it->bidi_it after backing up to previous newline. (Bug#9212)
746 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
748 * regex.c (re_comp): Protoize.
749 (re_exec): Fix return type.
750 (regexec): Fix type of `ret'. (Bug#9203)
752 2011-07-29 Paul Eggert <eggert@cs.ucla.edu>
754 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
755 This is needed if max-image-size is a floating-point number.
757 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
759 * print.c (print_object): Print empty symbol as ##.
761 * lread.c (read1): Read ## as empty symbol.
763 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
765 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
766 setting frame foreground color (Bug#9175).
767 (x_set_background_color): Likewise.
769 * nsmenu.m (-setText): Size tooltip dimensions precisely to
771 (EmacsTooltip -init): Remove bezels and add shadows to
774 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
775 or scroll bar (Bug#8470).
777 * nsfont.m (nsfont_open): Remove assignment to voffset and
778 unnecessary vars hshink, expand, hd, full_height, min_height.
779 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
781 * nsterm.h (nsfont_info): Remove voffset field.
783 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
785 Implement strike-through and overline on NextStep (Bug#8863).
787 * nsfont.m (nsfont_open): Use underline position provided by font,
788 instead of hard-coded value of 2.
789 (nsfont_draw): Call ns_draw_text_decoration instead.
791 * nsterm.h: Add declaration for ns_draw_text_decoration.
793 * nsterm.m (ns_draw_text_decoration): New function for drawing
794 underline, overline, and strike-through.
795 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
796 ns_draw_text_decoration. Change treatment of cursor drawing to
797 accomodate underlining, etc.
799 2011-07-28 Eli Zaretskii <eliz@gnu.org>
801 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
804 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
806 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
807 Without this fix, if a signal arrives just after memory fills up,
808 'malloc' might be invoked reentrantly.
810 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
811 In other words, assume that every image size is allowed, on non-X
812 hosts. This assumption is probably wrong, but it lets Emacs compile.
814 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
816 * regex.c (re_iswctype): Convert return values to boolean.
818 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
820 * xdisp.c (compute_display_string_pos): Don't use cached display
821 string position if the buffer had its restriction changed.
824 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
826 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
828 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
830 Integer signedness and overflow and related fixes. (Bug#9079)
832 * bidi.c: Integer size and overflow fixes.
833 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
834 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
835 (bidi_cache_find_level_change, bidi_cache_ensure_space)
836 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
837 (bidi_find_other_level_edge):
838 Use ptrdiff_t instead of EMACS_INT where either will do.
839 This works better on 32-bit hosts configured --with-wide-int.
840 (bidi_cache_ensure_space): Check for size-calculation overflow.
841 Use % rather than repeated addition, for better worst-case speed.
842 Don't set bidi_cache_size until after xrealloc returns, because it
844 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
845 (bidi_cache_ensure_space): Also check that the bidi cache size
846 does not exceed that of the largest Lisp string or buffer. See Eli
847 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
849 * alloc.c (__malloc_size_t): Remove.
850 All uses replaced by size_t. See Andreas Schwab's note
851 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
853 * image.c: Improve checking for integer overflow.
854 (check_image_size): Assume that f is nonnull, since
855 it is always nonnull in practice. This is one less thing to
856 worry about when checking for integer overflow later.
857 (x_check_image_size): New function, which checks for integer
858 overflow issues inside X.
859 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
860 This removes the need for a memory_full check.
861 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
862 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
863 (xbm_read_bitmap_data): Change locals back to 'int', since
864 their values must fit in 'int'.
865 (xpm_load_image, png_load, tiff_load):
866 Invoke x_create_x_image_and_pixmap earlier,
867 to avoid much needless work if the image is too large.
868 (tiff_load): Treat overly large images as if
869 x_create_x_image_and_pixmap failed, not as malloc failures.
870 (gs_load): Use x_check_image_size.
872 * gtkutil.c: Omit integer casts.
873 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
874 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
876 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
878 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
879 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
880 would wrongly return t on a 64-bit host.
882 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
883 The plain *_OVERFLOW macros run afoul of GCC bug 49705
884 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
885 and therefore cause GCC to emit a bogus diagnostic in some cases.
887 * image.c: Integer signedness and overflow and related fixes.
888 This is not an exhaustive set of fixes, but it's time to
889 record what I've got.
890 (lookup_pixel_color, check_image_size): Remove redundant decls.
891 (check_image_size): Don't assume that arbitrary EMACS_INT values
892 fit in 'int', or that arbitrary 'double' values fit in 'int'.
893 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
894 (tiff_load, imagemagick_load_image):
895 Check for overflow in size calculations.
896 (x_create_x_image_and_pixmap): Remove unnecessary test for
897 xmalloc returning NULL; that can't happen.
898 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
899 (xpm_color_bucket): Use better integer hashing function.
900 (xpm_cache_color): Don't possibly over-allocate memory.
901 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
903 Use ptrdiff_t, not int or size_t, to record sizes.
904 (png_load): Don't assume values greater than 2**31 fit in 'int'.
905 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
906 either works, as we prefer signed integers.
907 (tiff_read_from_memory, tiff_write_from_memory):
908 Return tsize_t, not size_t, since that's what the TIFF API wants.
909 (tiff_read_from_memory): Don't fail simply because the read would
910 go past EOF; instead, return a short read.
911 (tiff_load): Omit no-longer-needed casts.
912 (Fimagemagick_types): Don't assume size fits into 'int'.
914 Improve hashing quality when configured --with-wide-int.
915 * fns.c (hash_string): New function, taken from sxhash_string.
916 Do not discard information about ASCII character case; this
917 discarding is no longer needed.
918 (sxhash-string): Use it. Change sig to match it. Caller changed.
919 * lisp.h: Declare it.
920 * lread.c (hash_string): Remove, since we now use fns.c's version.
921 The fns.c version returns a wider integer if --with-wide-int is
922 specified, so this should help the quality of the hashing a bit.
924 * emacs.c: Integer overflow minor fix.
925 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
926 Define only if GNU_LINUX.
927 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
929 * dispnew.c: Integer signedness and overflow fixes.
930 Remove unnecessary forward decls, that were a maintenance hassle.
931 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
933 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
934 (scrolling_window): Use ptrdiff_t, not int, for byte count.
935 (prepare_desired_row, line_draw_cost):
936 Use int, not unsigned, where either works.
937 (save_current_matrix, restore_current_matrix):
938 Use ptrdiff_t, not size_t, where either works.
939 (init_display): Check for overflow more accurately, and without
940 relying on undefined behavior.
942 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
943 Remove, replacing with the new symbols in lisp.h. All uses changed.
944 * fileio.c (make_temp_name):
945 * filelock.c (lock_file_1, lock_file):
946 * xdisp.c (message_dolog):
947 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
948 Use pMd etc. instead.
949 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
950 replacing the pWIDE etc. symbols removed from editfns.c.
952 * keyboard.h (num_input_events): Now uintmax_t.
953 This is (very slightly) less likely to mess up due to wraparound.
956 * buffer.c: Integer signedness fixes.
957 (alloc_buffer_text, enlarge_buffer_text):
958 Use ptrdiff_t rather than size_t when either will do, as we prefer
961 * alloc.c: Integer signedness and overflow fixes.
962 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
963 (__malloc_size_t): Default to size_t, not to int.
964 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
965 (Fgarbage_collect, mark_object_loop_halt, mark_object):
966 Prefer ptrdiff_t to size_t when either would do, as we prefer
968 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
969 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
970 Now const. Initialize with values that are in range even if char
972 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
973 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
974 These functions do the right thing with sizes > 2**32.
975 (check_depth): Now ptrdiff_t, not int.
976 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
977 Adjust to new way of storing sizes. Check for size overflow bugs
979 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
980 slightly wrong anyway, as it missed one instance of
981 XMALLOC_OVERRUN_CHECK_OVERHEAD.
982 (refill_memory_reserve): Omit needless cast to size_t.
983 (mark_object_loop_halt): Mark as externally visible.
985 * xselect.c: Integer signedness and overflow fixes.
986 (Fx_register_dnd_atom, x_handle_dnd_message):
987 Use ptrdiff_t, not size_t, since we prefer signed.
988 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
989 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
990 x_dnd_atoms_size and x_dnd_atoms_length.
992 * doprnt.c: Prefer signed to unsigned when either works.
996 * xdisp.c (vmessage):
997 Use ptrdiff_t, not size_t, when using or implementing doprnt,
998 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
999 prefer signed arithmetic to avoid comparison confusion.
1000 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
1001 but is a bit tricky.
1003 Assume freestanding C89 headers, string.h, stdlib.h.
1004 * data.c, doprnt.c, floatfns.c, print.c:
1005 Include float.h unconditionally.
1006 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
1007 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
1008 * regex.c: Likewise for stddef.h, string.h.
1009 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
1010 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
1011 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
1012 (STDC_HEADERS): Remove obsolete defines.
1013 * sysdep.c: Include limits.h unconditionally.
1015 Assume support for memcmp, memcpy, memmove, memset.
1016 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
1017 * regex.c (memcmp, memcpy):
1018 Remove; we assume C89 now.
1020 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
1021 (__malloc_safe_bcopy): Remove; no longer needed.
1023 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
1024 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
1025 well either way, and we prefer signed to unsigned.
1027 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
1029 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
1030 closes the connection while we're reading (bug#9182).
1032 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
1034 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
1035 are specified (Bug#9168).
1037 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
1039 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
1040 Found by GCC static checking and --with-wide-int on a 32-bit host.
1042 2011-07-25 Eli Zaretskii <eliz@gnu.org>
1044 * xdisp.c (compute_display_string_pos): Fix logic of caching
1045 previous display string position. Initialize cached_prev_pos to
1046 -1. Fixes slow-down at the beginning of a buffer.
1048 2011-07-24 Eli Zaretskii <eliz@gnu.org>
1050 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
1051 for attrs[LFACE_FONTSET_INDEX].
1053 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
1055 * xml.c (parse_region): Remove unused local
1056 that was recently introduced.
1058 2011-07-23 Eli Zaretskii <eliz@gnu.org>
1060 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
1061 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
1063 * xdisp.c (move_it_in_display_line_to): Record the best matching
1064 position for TO_CHARPOS while scanning the line, and restore it on
1065 exit if none of the characters scanned was an exact match.
1066 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
1067 when exact match is impossible due to invisible text, and the
1068 lines are truncated.
1070 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
1072 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
1075 2011-07-22 Eli Zaretskii <eliz@gnu.org>
1077 Fix a significant slow-down of cursor motion with C-n, C-p,
1078 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
1079 auto-repeat under bidi redisplay in fontified buffers.
1080 * xdisp.c (compute_stop_pos_backwards): New function.
1081 (next_element_from_buffer): Call compute_stop_pos_backwards to
1082 find a suitable prev_stop when we find ourselves before
1084 (reseat): Don't look for prev_stop, as that could mean a very long
1086 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
1087 <cached_disp_overlay_modiff>: Cache for last found display string
1089 (compute_display_string_pos): Return the cached position if asked
1090 about the same buffer in the same area of character positions, and
1091 the buffer wasn't changed since the time the display string
1092 position was cached.
1094 2011-07-22 Eli Zaretskii <eliz@gnu.org>
1096 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
1097 is an integer, which is important for empty lines. (Bug#9149)
1099 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
1101 * frame.c (Fmodify_frame_parameters): In tty case, update the
1102 default face if necessary (Bug#4238).
1104 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
1106 * editfns.c (Fstring_to_char): No need to explain what a character
1107 is in the docstring (Bug#6576).
1109 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
1111 * xml.c (parse_region): Make sure we always return a tree.
1113 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
1115 * xml.c (parse_region): If a document contains only comments,
1118 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
1120 * xml.c (make_dom): Return comments, too.
1122 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
1125 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
1126 and the surrounding thread.
1127 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
1128 rather than fgets, and retry after EINTR. Otherwise, 'emacs
1129 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
1131 * s/openbsd.h (BROKEN_SIGIO): Define.
1132 * unexelf.c (unexec) [__OpenBSD__]:
1133 Don't update the .mdebug section of the Alpha COFF symbol table.
1135 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
1137 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
1140 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
1142 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
1143 This fixes some race conditions on the permissions of any newly
1146 * alloc.c (valid_pointer_p): Use pipe, not open.
1147 This fixes some permissions issues when debugging.
1149 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
1150 If fchown fails to set both uid and gid, try to set just gid,
1151 as that is sometimes allowed. Adjust the file's mode to eliminate
1152 setuid or setgid bits that are inappropriate if fchown fails.
1154 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
1156 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
1157 to compare Lisp_Objects.
1158 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
1159 global_gnutls_log_level, don't mistake it for a Lisp_Object.
1160 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
1162 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
1164 * lread.c (read_integer): Unread even EOF character.
1165 (read1): Likewise. Properly record start position of symbol.
1167 * lread.c (read1): Read `#:' as empty uninterned symbol if no
1168 symbol character follows.
1170 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
1172 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
1173 This works around a problem with the previous change to Fcopy_file.
1174 Recent glibc declares fchown with __attribute__((warn_unused_result)),
1175 and without this change, GCC might complain about discarding
1176 fchown's return value.
1178 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
1180 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
1182 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
1184 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
1186 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
1188 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
1189 it's used from the C level.
1191 * process.c: Use the same condition for POLL_FOR_INPUT in both
1192 keyboard.c and process.c (bug#1858).
1194 2011-07-09 Lawrence Mitchell <wence@gmx.li>
1196 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
1197 (Fgnutls_boot): Use it.
1199 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
1201 * doc.c (Fsubstitute_command_keys): Revert last change.
1203 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
1205 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
1206 quotes the next character, and doesn't affect other longer
1207 sequences (bug#8935).
1209 * lread.c (syms_of_lread): Clarify that is isn't only
1210 `eval-buffer' and `eval-defun' that's affected by
1211 `lexical-binding' (bug#8460).
1213 2011-07-15 Eli Zaretskii <eliz@gnu.org>
1215 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
1216 bidi redisplay when a line includes both an image and is
1219 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
1221 Fix minor problems found by static checking.
1222 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
1223 (elsz): Now a signed constant, not a size_t var. We prefer signed
1224 types to unsigned, to avoid integer comparison confusion. Without
1225 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
1226 "cannot optimize loop, the loop counter may overflow", a symptom
1228 * indent.c (Fvertical_motion): Mark locals as initialized.
1229 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
1231 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
1233 * search.c (Fre_search_backward): Mention `case-fold-search' in
1234 all the re_search_* functions (bug#8138).
1236 * keyboard.c (Fopen_dribble_file): Document when the file is

1247 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
1248 (reseat_to_string): Initialize bidi_it->string.s and
1249 bidi_it->string.schars.
1250 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
1251 NULL (avoids a crash in bidi_paragraph_init).
1252 Initialize itb.string.lstring.
1253 (init_iterator): Call bidi_init_it only of a valid
1254 buffer position was specified. Initialize paragraph_embedding to
1256 (reseat_to_string): Initialize the bidi iterator.
1257 (display_string): If we need to ignore text properties of
1258 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
1259 original value of -1 will not work with bidi.)
1260 (compute_display_string_pos): First arg is now struct
1261 `text_pos *'; all callers changed. Support display properties on
1263 (compute_display_string_end): Support display properties on Lisp
1265 (init_iterator, reseat_1, reseat_to_string): Initialize the
1266 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
1267 when iterating on a string not from display properties).
1268 (compute_display_string_pos, compute_display_string_end):
1269 Fix calculation of the object to scan. Fixes an error when using
1271 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
1272 base_level_stop; instead, set base_level_stop to BEGV.
1273 Fixes crashes in vertical-motion.
1274 (next_element_from_buffer): Improve commentary for when
1275 the iterator is before prev_stop.
1276 (init_iterator): Initialize bidi_p from the default value of
1277 bidi-display-reordering, not from buffer-local value. Use the
1278 buffer-local value only if initializing for buffer iteration.
1279 (handle_invisible_prop): Support invisible properties on strings
1280 that are being bidi-reordered.
1281 (set_iterator_to_next): Support bidi reordering of C strings and
1283 (next_element_from_string): Support bidi reordering of Lisp
1285 (handle_stop_backwards): Support Lisp strings as well.
1286 (display_string): Support display of R2L glyph rows.
1287 Use IT_STRING_CHARPOS when displaying from a Lisp string.
1288 (init_iterator): Don't initialize it->bidi_p for strings
1290 (reseat_to_string): Initialize it->bidi_p for strings here.
1291 (next_element_from_string, next_element_from_c_string)
1292 (next_element_from_buffer): Add xassert's for correspondence
1293 between IT's object being iterated and it->bidi_it.string
1295 (face_before_or_after_it_pos): Support bidi iteration.

1297 character that is not the first one in the visual order.
1298 (get_visually_first_element): New function, refactored from common
1299 parts of next_element_from_buffer, next_element_from_string, and
1300 next_element_from_c_string.
1301 (tool_bar_lines_needed, redisplay_tool_bar)
1302 (display_menu_bar): Force left-to-right direction. Add a FIXME
1303 comment for making that be controlled by a user option.
1304 (push_it, pop_it): Save and restore the state of the
1305 bidi iterator. Save and restore the bidi_p flag.
1306 (pop_it): Iterate out of display property for string iteration as
1308 (iterate_out_of_display_property): Support iteration over strings.
1309 (handle_single_display_spec): Set up it->bidi_it for iteration
1310 over a display string, and call bidi_init_it.

1313 iterator for displaying display or overlay strings.
1314 (forward_to_next_line_start): Don't use the shortcut if
1316 (back_to_previous_visible_line_start): If handle_display_prop
1317 pushed the iterator stack, restore the internal state of the bidi
1318 iterator by calling bidi_pop_it same number of times.
1319 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
1320 and we are bidi-iterating, don't decrement the iterator position;
1321 instead, set the first_elt flag in the bidi iterator, to produce
1323 (reseat_1): Remove redundant setting of string_from_display_prop_p.
1324 (push_display_prop): xassert that we are iterating a buffer.
1325 (push_it, pop_it): Save and restore paragraph_embedding member.
1326 (handle_single_display_spec, next_overlay_string)
1327 (get_overlay_strings_1, reseat_1, reseat_to_string)
1328 (push_display_prop): Set up the `unibyte' member of bidi_it.string
1329 correctly. Don't assume unibyte strings are not bidi-reordered.
1330 (compute_display_string_pos)
1331 (compute_display_string_end): Fix handling the case of C string.
1332 (push_it, pop_it): Save and restore from_disp_prop_p.
1333 (handle_single_display_spec, push_display_prop): Set the
1334 from_disp_prop_p flag.
1335 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
1336 (pop_it): Call iterate_out_of_display_property only if we are
1337 popping after iteration over a string that came from a display

1339 for verifying that the iterator position is in sync with the bidi
1341 (handle_single_display_spec, get_overlay_strings_1)
1342 (push_display_prop): Fix initialization of paragraph direction for
1343 string when that of the parent object is not yet determined.

1356 saving a temporary copy of the iterator and restoring it back.
1357 (back_to_previous_visible_line_start, reseat_1)
1358 (init_iterator): Empty the bidi cache "stack".
1359 (move_it_in_display_line_to): If iterator ended up at
1360 EOL, but we never saw any buffer positions smaller than
1361 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
1362 motion in bidi-reordered lines.
1363 (move_it_in_display_line_to): Record prev_method and prev_pos
1364 immediately before the call to set_iterator_to_next. Fixes cursor
1365 motion in bidi-reordered lines with stretch glyphs and strings
1366 displayed in margins. (Bug#8133) (Bug#8867)
1367 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past

1370 Save and restore bidi cache.
1372 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.

1374 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
1375 (bidi_cache_start): New variable.

1381 (bidi_level_of_next_char, bidi_find_other_level_edge)
1382 (bidi_move_to_visually_next): Compare cache index with
1383 bidi_cache_start rather than with zero.
1384 (bidi_fetch_char): Accept new argument STRING; all callers
1385 changed. Support iteration over a string. Support strings with
1386 display properties. Support unibyte strings. Fix the type of
1387 `len' according to what STRING_CHAR_AND_LENGTH expects.
1388 (bidi_paragraph_init, bidi_resolve_explicit_1)
1389 (bidi_resolve_explicit, bidi_resolve_weak)

1400 initialized to valid values.
1401 (bidi_init_it): Don't initialize charpos and bytepos with invalid
1403 (bidi_level_of_next_char): Allow the sentinel "position" to pass
1404 the test for valid cached positions. Fix the logic for looking up
1405 the sentinel state in the cache. GCPRO the Lisp string we are
1407 (bidi_push_it, bidi_pop_it): New functions.
1408 (bidi_initialize): Initialize the bidi cache start stack pointer.
1409 (bidi_cache_ensure_space): New function, refactored from part of

1416 (bidi_cache_find_level_change): xassert that bidi_cache_last_idx
1417 is valid if it's going to be used.

1750 (clone_per_buffer_values): Don't assume that

1792 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
1793 subseconds part to the entropy, as that's a bit more random.
1794 Prefer signed to unsigned, since the signedness doesn't matter and
1795 in general we prefer signed. When given a limit, use a
1796 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
1797 latter isn't right if USE_2_TAGS_FOR_INTS.

1816 * buffer.c (Foverlay_put): Say what the return value is
1819 * fileio.c (barf_or_query_if_file_exists): Check first if the file

1842 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

1942 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
1944 * eval.c (struct backtrace): Simplify and port the data structure.
1945 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
1946 signed bit field, as this assumption is not portable and it makes
1947 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
1948 "char debug_on_exit : 1" as this is not portable either; instead,
1949 use the portable "unsigned int debug_on_exit : 1". Remove unused
1950 member evalargs. Remove obsolete comments about cc bombing out.
1952 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

2024 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
2025 and use min_width/height from frames size_hint to set
2026 min_width/height (Bug#8919).
2028 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
2029 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.

2040 * process.c (wait_reading_process_output): Bypass select if
2041 waiting for a cell while ignoring keyboard input, and input is

2114 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
2116 Integer and buffer overflow fixes (Bug#8873).
2118 * print.c (printchar, strout): Check for string overflow.
2119 (PRINTPREPARE, printchar, strout):
2120 Don't set size unless allocation succeeds.
2122 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
2123 for sizes. Check for string overflow more accurately.
2124 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
2126 * macros.c: Integer and buffer overflow fixes.
2127 * keyboard.h (struct keyboard.kbd_macro_bufsize):
2128 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

2134 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
2136 * lread.c: Integer overflow fixes.
2137 (read_integer): Radix is now EMACS_INT, not int,
2138 to improve quality of diagnostics for out-of-range radices.
2139 Calculate buffer size correctly for out-of-range radices.
2140 (read1): Check for integer overflow in radices, and in
2141 read-circle numbers.
2142 (read_escape): Avoid int overflow.
2143 (Fload, openp, read_buffer_size, read1)
2144 (substitute_object_recurse, read_vector, read_list, map_obarray):

2157 (read_list): Don't assume file position fits in int.
2158 (read_escape): Check for hex character overflow.
2160 2011-06-22 Leo Liu <sdl.web@gmail.com>
2162 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
2163 Move to minibuffer.el.
2165 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
2167 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
2168 The following patches are for when GLYPH_DEBUG && !XASSERT.
2169 * dispextern.h (trace_redisplay_p, dump_glyph_string):
2170 * dispnew.c (flush_stdout):
2171 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
2172 Mark as externally visible.
2173 * dispnew.c (check_window_matrix_pointers): Now static.
2174 * dispnew.c (window_to_frame_vpos):
2175 * xfns.c (unwind_create_frame):
2176 * xterm.c (x_check_font): Remove unused local.
2177 * scroll.c (CHECK_BOUNDS):
2178 * xfaces.c (cache_fache): Rename local to avoid shadowing.
2179 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
2180 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
2181 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
2182 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
2184 (debug_method_add): Use va_list and vsprintf rather than relying
2185 on undefined behavior with wrong number of arguments.
2186 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
2187 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
2188 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
2189 since we're not interested in debugging glyphs with old libraries.
2190 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
2191 GCC 4.6.0's static checking.
2193 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
2195 Integer overflow and signedness fixes (Bug#8873).
2196 A few related buffer overrun fixes, too.

2204 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
2205 (x_create_bitmap_from_xpm_data):
2206 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
2207 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
2209 * xfaces.c (load_pixmap):
2210 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
2211 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
2212 (.bitmaps_last, struct x_output.icon_bitmap):
2213 Use ptrdiff_t, not int, for bitmap indexes.
2214 (x_allocate_bitmap_record): Check for size overflow.
2215 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
2217 Use ptrdiff_t, not int, for overlay counts.
2218 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
2219 * editfns.c (overlays_around, get_pos_property):
2220 * textprop.c (get_char_property_and_overlay):
2221 * xdisp.c (next_overlay_change, note_mouse_highlight):
2222 * xfaces.c (face_at_buffer_position):
2223 * buffer.c (OVERLAY_COUNT_MAX): New macro.
2224 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
2225 (Fnext_overlay_change, Fprevious_overlay_change)
2226 (mouse_face_overlay_overlaps, Foverlays_in):
2227 Use ptrdiff_t, not int, for sizes.
2228 (overlays_at, overlays_in): Check for size-calculation overflow.
2230 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
2232 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
2233 (x_session_initialize): Do not assume string length fits in int.
2235 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
2236 This is unlikely, but can occur if DPI is outlandish.
2238 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
2239 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
2241 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
2242 * xrdb.c (magic_file_p, search_magic_path):
2243 Omit last arg SUFFIX; it was always 0. All callers changed.
2244 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
2246 * xfont.c (xfont_match): Avoid need for strlen.
2248 * xfns.c: Don't assume strlen fits in int.
2249 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
2251 * xdisp.c (message_log_check_duplicate): Return intmax_t,
2252 not unsigned long, as we prefer signed integers. All callers changed.
2253 Detect integer overflow in repeat count.
2254 (message_dolog): Don't assume print length fits in 39 bytes.
2255 (display_mode_element): Don't assume strlen fits in int.
2257 * termcap.c: Don't assume sizes fit in int and never overflow.
2258 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
2259 (gobble_line): Check for size-calculation overflow.
2261 * minibuf.c (Fread_buffer):
2262 * lread.c (intern, intern_c_string):
2263 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
2264 Don't assume string length fits in int.
2266 * keyboard.c (parse_tool_bar_item):
2267 * gtkutil.c (style_changed_cb): Avoid need for strlen.
2269 * font.c: Don't assume string length fits in int.

2273 Don't assume integer property fits in fixnum.
2274 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
2276 * filelock.c: Fix some buffer overrun and integer overflow issues.
2277 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
2278 Reformulate so as not to need the command string.
2279 Invoke gzip -cd rather than gunzip, as it's more portable.
2280 (lock_info_type, lock_file_1, lock_file):
2281 Don't assume pid_t and time_t fit in unsigned long.
2282 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
2283 (current_lock_owner): Prefer signed type for sizes.
2284 Use memcpy, not strncpy, where memcpy is what is really wanted.
2285 Don't assume (via atoi) that time_t and pid_t fit in int.
2286 Check for time_t and/or pid_t out of range, e.g., via a network share.
2287 Don't alloca where an auto var works fine.
2289 * fileio.c: Fix some integer overflow issues.
2290 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
2291 Don't assume string length fits in int.
2292 (directory_file_name): Don't assume string length fits in long.
2293 (make_temp_name): Don't assume pid fits in int, or that its print
2294 length is less than 20.
2296 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
2298 * coding.c (make_subsidiaries): Don't assume string length fits in int.
2300 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
2302 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
2303 We prefer signed integers, even for size calculations.
2305 * emacs.c: Don't assume string length fits in 'int'.
2306 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
2307 (main): Don't invoke strlen when not needed.
2309 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

2312 * callproc.c (getenv_internal_1, getenv_internal)
2314 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
2316 * lread.c (invalid_syntax): Omit length argument.
2317 All uses changed. This doesn't fix a bug, but it simplifies the
2318 code away from its former Hollerith-constant appearance, and it's
2319 one less 'int' to worry about when looking at integer-overflow issues.
2320 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
2322 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
2323 This didn't break anything, but it didn't help either.
2324 It's confusing to put a bogus integer in a place where the actual
2325 value does not matter.
2326 (LIST_END_P): Remove unused macro and its bogus comment.
2327 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
2329 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
2330 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
2332 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
2333 We prefer signed types, and the value cannot exceed the EMACS_INT
2334 range anyway (because otherwise the length would not be representable).
2335 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
2336 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
2337 This avoids a GCC warning when WIDE_EMACS_INT.
2339 * indent.c (sane_tab_width): New function.
2340 (current_column, scan_for_column, Findent_to, position_indentation)
2341 (compute_motion): Use it. This is just for clarity.
2342 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
2344 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
2346 * lisp.h (lint_assume): New macro.
2347 * composite.c (composition_gstring_put_cache):
2348 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
2350 * editfns.c, insdel.c:
2351 Omit unnecessary forward decls, to simplify future changes.
2353 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
2355 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
2357 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
2358 Use much-faster test for byte-length change.
2359 Don't assume string byte-length fits in 'int'.
2360 Check that character arg fits in 'int'.
2361 (mapcar1): Declare byte as byte, for clarity.
2363 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
2365 * fns.c (concat): Catch string overflow earlier.
2366 Do not rely on integer wraparound.
2368 * dispextern.h (struct it.overlay_strings_charpos)
2369 (struct it.selective): Now EMACS_INT, not int.
2370 * xdisp.c (forward_to_next_line_start)
2371 (back_to_previous_visible_line_start)
2372 (reseat_at_next_visible_line_start, next_element_from_buffer):
2373 Don't arbitrarily truncate the value of 'selective' to int.
2375 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
2377 * composite.c: Don't truncate sizes to 'int'.
2378 (composition_gstring_p, composition_reseat_it)
2379 (composition_adjust_point): Use EMACS_INT, not int.
2380 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
2381 not EMACS_UINT, for indexes.
2383 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
2385 * buffer.c: Include <verify.h>.
2386 (struct sortvec.priority, struct sortstr.priority):
2387 Now EMACS_INT, not int.
2388 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
2389 (struct sortstr.size, record_overlay_string)
2390 (struct sortstrlist.size, struct sortlist.used):
2391 Don't truncate size to int.
2392 (record_overlay_string): Check for size-calculation overflow.
2393 (init_buffer_once): Check at compile-time, not run-time.
2395 2011-06-22 Jim Meyering <meyering@redhat.com>
2397 Don't leak an XBM-image-sized buffer
2398 * image.c (xbm_load): Free the image buffer after using it.
2400 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
2403 * composite.c (find_automatic_composition): Omit needless 'return 0;'
2404 that Sun C diagnosed.
2405 * fns.c (secure_hash): Fix pointer signedness issue.
2406 * intervals.c (static_offset_intervals): New function.
2407 (offset_intervals): Use it.
2409 2011-06-21 Leo Liu <sdl.web@gmail.com>
2412 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
2415 * fns.c (secure_hash): Rename from crypto_hash_function and change
2416 the first arg to accept symbols.
2417 (Fsecure_hash): New primitive.
2418 (syms_of_fns): New symbols.
2420 2011-06-20 Deniz Dogan <deniz@dogan.se>
2422 * process.c (Fset_process_buffer): Clarify return value in
2425 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
2427 * dispnew.c (add_window_display_history): Use BVAR.
2429 * xdisp.c (debug_method_add): Use BVAR.
2430 (check_window_end, dump_glyph_matrix, dump_glyph)
2431 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
2433 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
2436 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
2437 check till after the cache is created in init_frame_faces.
2439 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
2441 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
2443 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
2445 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
2446 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
2447 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
2449 Improve buffer-overflow checking (Bug#8873).
2450 * fileio.c (Finsert_file_contents):
2451 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
2452 Remove the old (too-loose) buffer overflow checks.
2453 They weren't needed, since make_gap checks for buffer overflow.
2454 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
2455 The old code merely checked for Emacs fixnum overflow, and relied
2456 on undefined (wraparound) behavior. The new code avoids undefined
2457 behavior, and also checks for ptrdiff_t and/or size_t overflow.
2459 * editfns.c (Finsert_char): Don't dump core with very negative counts.
2460 Tune. Don't use wider integers than needed. Don't use alloca.
2461 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
2463 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
2465 * insdel.c, lisp.h (buffer_overflow): New function.
2466 (insert_from_buffer_1, replace_range, replace_range_2):
2467 * insdel.c (make_gap_larger):
2468 * editfns.c (Finsert_char):
2469 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
2471 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
2473 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
2475 Integer overflow and signedness fixes (Bug#8873).
2477 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
2478 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
2480 * fileio.c: Don't assume EMACS_INT fits in off_t.
2481 (emacs_lseek): New static function.
2482 (Finsert_file_contents, Fwrite_region): Use it.
2483 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
2485 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
2487 * fns.c: Don't overflow int when computing a list length.
2488 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
2489 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
2490 truncation on 64-bit hosts. Check for QUIT every
2491 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
2492 faster and is responsive enough.
2493 (Flength): Report an error instead of overflowing an integer.
2494 (Fsafe_length): Return a float if the value is not representable
2495 as a fixnum. This shouldn't happen except in contrived situations.
2496 (Fnthcdr, Fsort): Don't assume list length fits in int.
2497 (Fcopy_sequence): Don't assume vector length fits in int.
2499 * alloc.c: Check that resized vectors' lengths fit in fixnums.
2500 (header_size, word_size): New constants.
2501 (allocate_vectorlike): Don't check size overflow here.
2502 (allocate_vector): Check it here instead, since this is the only
2503 caller of allocate_vectorlike that could cause overflow.
2504 Check that the new vector's length is representable as a fixnum.
2506 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
2507 The previous code was bogus. For example, next_almost_prime (32)
2508 returned 39, which is undesirable as it is a multiple of 3; and
2509 next_almost_prime (24) returned 25, which is a multiple of 5 so
2510 why was the code bothering to check for multiples of 7?
2512 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
2514 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
2516 Variadic C functions now count arguments with ptrdiff_t.
2517 This partly undoes my 2011-03-30 change, which replaced int with size_t.
2518 Back then I didn't know that the Emacs coding style prefers signed int.
2519 Also, in the meantime I found a few more instances where arguments
2520 were being counted with int, which may truncate counts on 64-bit
2521 machines, or EMACS_INT, which may be unnecessarily wide.
2522 * lisp.h (struct Lisp_Subr.function.aMANY)
2523 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
2524 Arg counts are now ptrdiff_t, not size_t.
2525 All variadic functions and their callers changed accordingly.
2526 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
2527 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
2528 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
2529 * callint.c (Fcall_interactively): Check arg count for overflow,
2530 to avoid potential buffer overrun. Use signed char, not 'int',
2531 for 'varies' array, so that we needn't bother to check its size
2532 calculation for overflow.
2533 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
2534 * eval.c (apply_lambda):
2535 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
2536 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
2537 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
2539 * callint.c (Fcall_interactively): Don't use index var as event count.
2541 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
2542 * mem-limits.h (SIZE): Remove; no longer used.
2544 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
2546 Remove unnecessary casts.
2547 * xterm.c (x_term_init):
2548 * xfns.c (x_set_border_pixel):
2549 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
2550 These aren't needed now that we assume ANSI C.
2552 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
2553 It's more likely to cause problems (due to unsigned overflow)
2556 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
2558 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
2560 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
2562 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
2564 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
2566 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
2568 GLYPH_CODE_FACE returns EMACS_INT, not int.
2569 * dispextern.h (merge_faces):
2570 * xfaces.c (merge_faces):
2571 * xdisp.c (get_next_display_element, next_element_from_display_vector):
2572 Don't assume EMACS_INT fits in int.
2574 * character.h (CHAR_VALID_P): Remove unused parameter.
2575 * fontset.c, lisp.h, xdisp.c: All uses changed.
2577 * editfns.c (Ftranslate_region_internal): Omit redundant test.
2579 * fns.c (concat): Minor tuning based on overflow analysis.
2580 This doesn't fix any bugs. Use int to hold character, instead
2581 of constantly refetching from Emacs object. Use XFASTINT, not
2582 XINT, for value known to be a character. Don't bother comparing
2583 a single byte to 0400, as it's always less.
2585 * floatfns.c (Fexpt):
2586 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
2588 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
2591 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
2593 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
2594 Without this fix, on a 64-bit host (aset S 0 4294967386) would
2595 incorrectly succeed when S was a string, because 4294967386 was
2596 truncated before it was used.
2598 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
2599 Otherwise, an out-of-range integer could cause undefined behavior
2602 * composite.c: Use int, not EMACS_INT, for characters.
2603 (fill_gstring_body, composition_compute_stop_pos): Use int, not
2604 EMACS_INT, for values that are known to be in character range.
2605 This doesn't fix any bugs but is the usual style inside Emacs and
2606 may generate better code on 32-bit machines.
2608 Make sure a 64-bit char is never passed to ENCODE_CHAR.
2609 This is for reasons similar to the recent CHAR_STRING fix.
2610 * charset.c (Fencode_char): Check that character arg is actually
2611 a character. Pass an int to ENCODE_CHAR.
2612 * charset.h (ENCODE_CHAR): Verify that the character argument is no
2613 wider than 'int', as a compile-time check to prevent future regressions
2616 * character.c (char_string): Remove unnecessary casts.
2618 Make sure a 64-bit char is never passed to CHAR_STRING.
2619 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
2620 by silently ignoring the top 32 bits, allowing some values
2621 that were far too large to be valid characters.
2622 * character.h: Include <verify.h>.
2623 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
2624 arguments are no wider than unsigned, as a compile-time check
2625 to prevent future regressions in this area.
2627 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
2628 (Fsubst_char_in_region):
2630 * xdisp.c (decode_mode_spec_coding):
2631 Adjust to CHAR_STRING's new requirement.
2632 * editfns.c (Finsert_char, Fsubst_char_in_region):
2633 * fns.c (concat): Check that character args are actually
2634 characters. Without this test, these functions did the wrong
2635 thing with wildly out-of-range values on 64-bit hosts.
2637 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
2638 These casts should not be needed on 32-bit hosts, either.
2639 * keyboard.c (read_char):
2640 * lread.c (Fload): Remove casts to unsigned.
2642 * lisp.h (UNSIGNED_CMP): New macro.
2643 This fixes comparison bugs on 64-bit hosts.
2644 (ASCII_CHAR_P): Use it.
2645 * casefiddle.c (casify_object):
2646 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
2647 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
2648 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
2649 * dispextern.h (FACE_FROM_ID):
2650 * keyboard.c (read_char): Use UNSIGNED_CMP.
2652 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
2653 not to EMACS_INT, to avoid GCC warning.
2655 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
2657 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
2658 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
2659 isn't needed on 32-bit machines.
2661 * buffer.c (Fgenerate_new_buffer_name):
2662 Use EMACS_INT for count, not int.
2663 (advance_to_char_boundary): Return EMACS_INT, not int.
2665 * data.c (Qcompiled_function): Now static.
2667 * window.c (window_body_lines): Now static.
2669 * image.c (gif_load): Rename local to avoid shadowing.
2671 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
2672 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
2673 * alloc.c (make_save_value): Integer argument is now of type
2675 (mark_object): Use ptrdiff_t, not int.
2676 * lisp.h (pD): New macro.
2677 * print.c (print_object): Use it.
2679 * alloc.c: Use EMACS_INT, not int, to count objects.
2680 (total_conses, total_markers, total_symbols, total_vector_size)
2681 (total_free_conses, total_free_markers, total_free_symbols)
2682 (total_free_floats, total_floats, total_free_intervals)
2683 (total_intervals, total_strings, total_free_strings):
2684 Now EMACS_INT, not int. All uses changed.
2685 (Fgarbage_collect): Compute overall total using a double, so that
2686 integer overflow is less likely to be a problem. Check for overflow
2687 when converting back to an integer.
2688 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
2689 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
2690 These were 'int' variables that could overflow on 64-bit hosts;
2691 they were never used, so remove them instead of repairing them.
2692 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
2693 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
2694 Previously, this ceilinged at INT_MAX, but that doesn't work on
2696 (allocate_pseudovector): Don't use EMACS_INT when int would do.
2698 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
2699 (allocate_vectorlike): Check for ptrdiff_t overflow.
2700 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
2701 when a (possibly-narrower) signed value would do just as well.
2702 We prefer using signed arithmetic, to avoid comparison confusion.
2704 * alloc.c: Catch some string size overflows that we were missing.
2705 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
2706 for convenience in STRING_BYTES_MAX.
2707 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
2708 The definition here is exact; the one in lisp.h was approximate.
2709 (allocate_string_data): Check for string overflow. This catches
2710 some instances we weren't catching before. Also, it catches
2711 size_t overflow on (unusual) hosts where SIZE_MAX <= min
2712 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
2713 and ptrdiff_t and EMACS_INT are both 64 bits.
2715 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
2716 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
2717 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
2719 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
2721 * alloc.c (Fmake_string): Check for out-of-range init.
2723 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
2725 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
2727 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
2729 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
2730 xg_get_default_scrollbar_width.
2732 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
2733 (int_gtk_range_get_value): Move to the scroll bar part of the file.
2734 (style_changed_cb): Call update_theme_scrollbar_width and call
2735 x_set_scroll_bar_default_width and xg_frame_set_char_size for
2736 all frames (Bug#8505).
2737 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
2738 Call gtk_window_set_resizable if HAVE_GTK3.
2739 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
2740 and height if HAVE_GTK3 (Bug#8505).
2741 (scroll_bar_width_for_theme): New variable.
2742 (update_theme_scrollbar_width): New function.
2743 (xg_get_default_scrollbar_width): Move code to
2744 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
2745 (xg_initialize): Call update_theme_scrollbar_width.
2747 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
2749 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
2751 2011-06-12 Martin Rudalics <rudalics@gmx.at>
2753 * frame.c (make_frame): Call other_buffer_safely instead of
2756 * window.c (temp_output_buffer_show): Call display_buffer with
2757 second argument Vtemp_buffer_show_specifiers and reset latter
2758 immediately after the call.
2759 (Vtemp_buffer_show_specifiers): New variable.
2760 (auto_window_vscroll_p, next_screen_context_lines)
2761 (Vscroll_preserve_screen_position): Remove leading asterisks from
2764 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
2766 Fix minor problems found by GCC 4.6.0 static checking.
2767 * buffer.c (Qclone_number): Remove for now, as it's unused.
2768 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
2769 (record_buffer): Remove unused local.
2770 * frame.c (other_visible_frames, frame_buffer_list): Now static.
2771 (set_frame_buffer_list): Remove; unused.
2772 * frame.h (other_visible_frames): Remove decl.
2773 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
2774 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
2775 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
2777 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
2778 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
2779 Define only if HAVE_GPM.
2780 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
2781 (update_hints_inhibit): Remove; never set. All uses removed.
2782 * widgetprv.h (emacsFrameClassRec): Remove decl.
2783 * window.c (delete_deletable_window): Now returns void, since it
2784 wasn't returning anything.
2785 (compare_window_configurations): Remove unused locals.
2786 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
2787 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
2788 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
2789 the same widths as pointers. This follows up on the 2011-05-06 patch.
2790 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
2791 * xterm.h: Likewise.
2792 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
2794 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
2796 * makefile.w32-in: Update dependencies.
2797 (LISP_H): Add lib/intprops.h.
2799 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
2801 * image.c (gif_load): Add animation frame delay to the metadata.
2802 (syms_of_image): Use DEFSYM. New symbol `delay'.

3282 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
3283 (bidi_level_of_next_char, bidi_move_to_visually_next):
3284 Support character positions inside a run of characters covered by a
3286 (bidi_paragraph_init, bidi_resolve_explicit_1)
3287 (bidi_level_of_next_char): Call bidi_fetch_char and
3288 bidi_fetch_char_advance instead of FETCH_CHAR and
3290 (bidi_init_it): Initialize new members.
3291 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
3293 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
3294 instead of using explicit *_CHAR codes.
3295 (bidi_resolve_explicit, bidi_resolve_weak):
3296 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
3297 bidirectional text is supported only in multibyte buffers.
3298 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
3299 it to initialize the frame_window_p member of struct bidi_it.
3300 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
3301 (bidi_resolve_explicit, bidi_resolve_weak)
3302 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
3303 bidi_it->nchars is non-positive.
3304 (bidi_level_of_next_char): Don't try to lookup the cache for the
3305 next/previous character if nothing is cached there yet, or if we
3306 were just reseat()'ed to a new position.
3308 * xdisp.c (set_cursor_from_row): Set start and stop points
3309 according to the row's direction when priming the loop that looks
3310 for the glyph on which to display cursor.
3311 (single_display_spec_intangible_p): Function deleted.
3312 (display_prop_intangible_p): Reimplement to call
3313 handle_display_spec instead of single_display_spec_intangible_p.
3314 Accept 3 additional arguments needed by handle_display_spec.
3315 This fixes incorrect cursor motion across display property with complex
3316 values: lists, `(when COND...)' forms, etc.
3317 (single_display_spec_string_p): Support property values that are
3318 lists with the argument STRING its top-level element.
3319 (display_prop_string_p): Fix the condition for processing a
3320 property that is a list to be consistent with handle_display_spec.
3321 (handle_display_spec): New function, refactored from the
3322 last portion of handle_display_prop.
3323 (compute_display_string_pos): Accept additional argument
3324 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
3325 value of a `display' property is a "replacing spec".
3326 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
3327 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
3328 the display property, but just return a value indicating whether
3329 the display property will replace the characters it covers.
3330 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
3331 frame_window_p members of struct bidi_it.
3332 (compute_display_string_pos, compute_display_string_end):
3334 (push_it): Accept second argument POSITION, where pop_it should
3335 jump to continue iteration.
3336 (reseat_1): Initialize bidi_it.disp_pos.
3338 * keyboard.c (adjust_point_for_property): Adjust the call to
3339 display_prop_intangible_p to its new signature.
3341 * dispextern.h (struct bidi_it): New member frame_window_p.
3342 (bidi_init_it): Update prototypes.
3343 (display_prop_intangible_p): Update prototype.
3344 (compute_display_string_pos, compute_display_string_end):
3346 (struct bidi_it): New members nchars and disp_pos. ch_len is now
3349 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
3351 Malloc failure behavior now depends on size of allocation.
3352 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
3353 * lisp.h: Change signatures accordingly.
3354 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
3355 All callers changed. (Bug#8762)
3357 * gnutls.c: Use Emacs's memory allocators.
3358 Without this change, the gnutls library would invoke malloc etc.
3359 directly, which causes problems on non-SYNC_INPUT hosts, and which
3360 runs afoul of improving memory_full behavior. (Bug#8761)
3361 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
3362 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
3363 xfree instead of the default malloc, realloc, free.
3364 (Fgnutls_boot): No need to check for memory allocation failure,
3365 since xmalloc does that for us.
3367 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
3368 * category.c (hash_get_category_set):
3369 * ccl.c (ccl_driver):

3383 * image.c (make_image, search_image_cache, lookup_image)
3384 (xpm_put_color_table_h):
3385 * lisp.h (struct Lisp_Hash_Table):
3386 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
3387 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
3388 for hashes and hash indexes, instead of 'unsigned' and 'int'.
3389 * alloc.c (allocate_vectorlike):
3390 Check for overflow in vector size calculations.
3391 * ccl.c (ccl_driver):
3392 Check for overflow when converting EMACS_INT to int.
3393 * fns.c, image.c: Remove unnecessary static decls that would otherwise
3394 need to be updated by these changes.
3395 * fns.c (make_hash_table, maybe_resize_hash_table):
3396 Check for integer overflow with large hash tables.
3397 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
3398 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
3399 (SXHASH_REDUCE): New macro.
3400 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
3401 Use it instead of discarding useful hash info with large hash values.
3402 (sxhash_float): New function.
3403 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
3404 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
3405 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
3406 Rewrite to use FIXNUM_BITS, as this simplifies things.
3407 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
3408 Adjust signatures to match updated version of code.
3409 (consing_since_gc): Now EMACS_INT, since a single hash table can
3410 use more than INT_MAX bytes.
3412 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
3414 Make it possible to build with GCC-4.6+ -O2 -flto.
3416 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
3418 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
3420 * minibuf.c (get_minibuffer, read_minibuf_unwind):
3421 Call minibuffer-inactive-mode.
3423 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
3425 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
3426 Update dependencies.
3428 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3430 * data.c (init_data): Remove code for UTS, this system is not
3433 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3435 Don't force ./temacs to start in terminal mode.
3437 * frame.c (make_initial_frame): Initialize faces in all cases, not
3438 only when CANNOT_DUMP is defined.
3439 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
3441 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3443 * dispnew.c (add_window_display_history): Use const for the string
3444 pointer. Remove declaration, not needed.
3446 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3448 Use 'inline', not 'INLINE'.
3449 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
3450 * alloc.c, fontset.c (INLINE): Remove.
3451 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
3452 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
3453 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
3454 * gmalloc.c (register_heapinfo): Use inline unconditionally.
3455 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
3457 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3459 Make it possible to run ./temacs.
3461 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
3462 syms_of_callproc does the same thing. Remove test for
3463 "initialized", do it in the caller.
3464 * emacs.c (main): Avoid calling set_initial_environment when dumping.
3466 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
3468 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
3469 (read_minibuf): Use get_minibuffer.
3470 (syms_of_minibuf): Use DEFSYM.
3471 (Qmetadata): New var.
3472 * data.c (Qbuffer): Don't make it static.
3473 (syms_of_data): Use DEFSYM.
3475 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3477 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
3478 (CCL_CODE_MIN): New macro.
3480 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
3482 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
3484 * eval.c (Qdebug): Now static.
3485 * lisp.h (Qdebug): Remove decl. This reverts a part of the
3486 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
3487 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
3489 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3491 * image.c: Various fixes to ImageMagick code comments.
3492 (Fimagemagick_types): Doc fix.
3494 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
3496 Minor fixes prompted by GCC 4.6.0 warnings.
3498 * xselect.c (converted_selections, conversion_fail_tag): Now static.
3500 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
3501 (x_clipboard_manager_save_all): Move extern decl to ...
3502 * xterm.h: ... here, so that it can be checked for consistency.
3504 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3506 * xselect.c (x_clipboard_manager_save_frame)
3507 (x_clipboard_manager_save_all): New functions.
3508 (Fx_clipboard_manager_save): Lisp function deleted.
3510 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
3511 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
3513 * xterm.h: Update prototype.
3515 2011-05-28 William Xu <william.xwl@gmail.com>
3517 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
3520 2011-05-28 Jim Meyering <meyering@redhat.com>
3522 Avoid a sign-extension bug in crypto_hash_function.
3523 * fns.c (to_uchar): Define.
3524 (crypto_hash_function): Use it to convert some newly-signed
3525 variables to unsigned, to avoid sign-extension bugs. For example,
3526 without this change, (md5 "truc") would evaluate to
3527 45723a2aff78ff4fff7fff1114760e62 rather than the expected
3528 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
3529 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
3531 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3533 Integer overflow fixes.
3535 * dbusbind.c: Serial number integer overflow fixes.
3536 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
3537 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
3538 to hold a serial number that is too large for a fixnum.
3539 (Fdbus_method_return_internal, Fdbus_method_error_internal):
3540 Check for serial numbers out of range. Decode any serial number
3541 that was so large that it became a float. (Bug#8722)
3543 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
3544 (Fdbus_call_method, Fdbus_call_method_asynchronously):
3545 Use XFASTINT rather than XUINT when numbers are nonnegative.
3546 (xd_append_arg, Fdbus_method_return_internal):
3547 (Fdbus_method_error_internal): Likewise. Also, for unsigned
3548 arguments, check that Lisp number is nonnegative, rather than
3549 silently wrapping negative numbers around. (Bug#8722)
3550 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
3553 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
3555 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
3557 ccl: add integer overflow checks
3558 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
3559 (IN_INT_RANGE): New macros.
3560 (ccl_driver): Use them to check for integer overflow when
3561 decoding a CCL program. Many of the new checks are whether XINT (x)
3562 fits in int; it doesn't always, on 64-bit hosts. The new version
3563 doesn't catch all possible integer overflows, but it's an
3564 improvement. (Bug#8719)
3566 * alloc.c (make_event_array): Use XINT, not XUINT.
3567 There's no need for unsigned here.
3569 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
3570 This follows up to the 2011-05-06 change that substituted uintptr_t
3571 for EMACS_INT. This case wasn't caught back then.
3573 Rework Fformat to avoid integer overflow issues.
3574 * editfns.c: Include <float.h> unconditionally, as it's everywhere
3575 now (part of C89). Include <verify.h>.
3576 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
3577 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
3578 (Fformat): Avoid the prepass trying to compute sizes; it was only
3579 approximate and thus did not catch overflow reliably. Instead, walk
3580 through the format just once, formatting and computing sizes as we go,
3581 checking for integer overflow at every step, and allocating a larger
3582 buffer as needed. Keep track separately whether the format is
3583 multibyte. Keep only the most-recently calculated precision, rather
3584 than them all. Record whether each argument has been converted to
3585 string. Use EMACS_INT, not int, for byte and char and arg counts.
3586 Support field widths and precisions larger than INT_MAX. Avoid
3587 sprintf's undefined behavior with conversion specifications such as %#d
3588 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
3589 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
3590 formatting out-of-range floating point numbers with int
3593 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
3595 * data.c: Avoid integer truncation in expressions involving floats.
3596 * data.c: Include <intprops.h>.
3597 (arith_driver): When there's an integer overflow in an expression
3598 involving floating point, convert the integers to floating point
3599 so that the resulting value does not suffer from catastrophic
3600 integer truncation. For example, on a 64-bit host (* 4
3601 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
3602 Do not rely on undefined behavior after integer overflow.
3604 merge count_size_as_multibyte, parse_str_to_multibyte
3605 * character.c, character.h (count_size_as_multibyte):
3606 Rename from parse_str_to_multibyte; all uses changed.
3607 Check for integer overflow.
3608 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
3609 since it's now a duplicate of the other. This is more of
3610 a character than a buffer op, so better that it's in character.c.
3611 * fns.c, print.c: Adjust to above changes.
3613 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
3615 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
3617 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3619 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3620 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
3621 (x_clipboard_manager_save): Now static.
3622 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
3624 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3625 (crypto_hash_function): Now static.
3626 Fix pointer signedness problems. Avoid unnecessary initializations.
3628 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
3630 * termhooks.h (Vselection_alist): Make it terminal-local.
3632 * terminal.c (create_terminal): Initialize it.
3634 * xselect.c: Support for clipboard managers.
3635 (Vselection_alist): Move to termhooks.h as terminal-local var.

3640 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
3641 (x_own_selection, x_get_local_selection, x_convert_selection):
3642 New arg, specifying work frame. Use terminal-local Vselection_alist.
3643 (some_frame_on_display): Delete unused function.
3644 (Fx_own_selection_internal, Fx_get_selection_internal)
3645 (Fx_disown_selection_internal, Fx_selection_owner_p)
3646 (Fx_selection_exists_p): New optional frame arg.
3647 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
3648 (x_handle_selection_clear): Don't treat other terminals with the
3649 same keyboard specially. Use the terminal-local Vselection_alist.
3650 (x_clear_frame_selections): Use Frun_hook_with_args.
3652 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
3654 * xterm.h: Add support for those atoms.
3656 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
3658 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
3659 (converted_selections, conversion_fail_tag): New global variables.
3660 (x_selection_request_lisp_error): Free the above.
3661 (x_get_local_selection): Remove unnecessary code.
3662 (x_reply_selection_request): Args changed; handle arbitrary array
3663 of converted selections stored in converted_selections.
3664 Separate the XChangeProperty and SelectionNotify steps.
3665 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
3666 (x_convert_selection): New function.
3667 (x_handle_selection_event): Simplify.
3668 (x_get_foreign_selection): Don't ignore incoming requests while
3669 waiting for an answer; this will fail when we implement
3670 SAVE_TARGETS, and seems unnecessary anyway.
3671 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
3672 (Vx_sent_selection_functions): Doc fix.
3674 2011-05-26 Leo Liu <sdl.web@gmail.com>
3676 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
3678 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3680 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
3682 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
3683 for fringe update if it has periodic bitmap.
3684 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
3685 and fringe_bitmap_periodic_p.
3687 * fringe.c (get_fringe_bitmap_data): New function.
3688 (draw_fringe_bitmap_1, update_window_fringes): Use it.
3689 (update_window_fringes): Record periodicity of fringe bitmap in glyph
3690 row. Mark glyph row for fringe update if periodicity changed.
3692 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
3693 for fringe update unless it has periodic bitmap.
3695 2011-05-25 Kenichi Handa <handa@m17n.org>
3697 * xdisp.c (get_next_display_element): Set correct it->face_id for
3698 a static composition.

3711 * gnutls.c: Remove unused macros.
3712 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
3713 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
3714 Remove macros that are defined and never used.
3715 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
3717 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3719 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
3720 (Fx_get_selection_internal): Minor cleanup.
3721 (Fx_own_selection_internal): Rename arguments for consistency with
3724 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3726 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
3728 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3730 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
3732 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3734 * dispnew.c (scrolling_window): Don't exclude the case that the
3735 last enabled row in the desired matrix touches the bottom boundary.
3737 2011-05-21 Glenn Morris <rgm@gnu.org>
3739 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
3740 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
3741 and add some more files.
3743 2011-05-20 Eli Zaretskii <eliz@gnu.org>
3745 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
3746 report_file_error introduced by the change from 2011-05-07.
3748 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
3750 * systime.h (Time): Define only if emacs is defined.
3751 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
3752 where the include path doesn't have X11/X.h by default. See
3753 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
3755 2011-05-20 Kenichi Handa <handa@m17n.org>
3757 * composite.c (find_automatic_composition): Fix previous change.
3759 2011-05-20 Glenn Morris <rgm@gnu.org>
3761 * lisp.mk: New file, split from Makefile.in.
3762 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
3763 (shortlisp): Remove.
3764 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
3766 2011-05-19 Glenn Morris <rgm@gnu.org>
3768 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
3769 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
3770 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
3771 (lisp): Set the order to that of loadup.el.
3772 (shortlisp): Make it a copy of $lisp.
3773 (SOME_MACHINE_LISP): Remove.
3774 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
3775 Use just $shortlisp, not $SOME_MACHINE_LISP too.
3777 2011-05-18 Kenichi Handa <handa@m17n.org>
3779 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
3780 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
3781 (find_automatic_composition): Mostly rewrite for efficiency.
3783 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
3785 * makefile.w32-in: Update dependencies.
3787 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
3789 * menu.c: Include limits.h (fixes the MS-Windows build broken by
3790 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
3792 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
3794 Fix some integer overflow issues, such as string length overflow.
3796 * insdel.c (count_size_as_multibyte): Check for string overflow.
3798 * character.c (lisp_string_width): Check for string overflow.
3799 Use EMACS_INT, not int, for string indexes and lengths; in
3800 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
3801 the resulting string length overflows an EMACS_INT; instead,
3802 report a string overflow if no precision given. When checking for
3803 precision exhaustion, use a check that cannot possibly have
3804 integer overflow. (Bug#8675)
3805 * character.h (lisp_string_width): Adjust to new signature.
3807 * alloc.c (string_overflow): New function.
3808 (Fmake_string): Use it. This doesn't change behavior, but saves
3809 a few bytes and will simplify future changes.
3810 * character.c (string_escape_byte8): Likewise.
3811 * lisp.h (string_overflow): New decl.
3813 Fixups, following up to the user-interface timestamp change.
3814 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
3815 for UI timestamps, instead of unsigned long.
3816 * msdos.c (mouse_get_pos): Likewise.
3817 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
3818 * w32gui.h (Time): Define by including "systime.h" rather than by
3819 declaring it ourselves. (Bug#8664)
3821 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
3822 * image.c (clear_image_cache): Likewise.
3824 * term.c (term_mouse_position): Don't assume time_t wraparound.
3826 Be more systematic about user-interface timestamps.
3827 Before, the code sometimes used 'Time', sometimes 'unsigned long',
3828 and sometimes 'EMACS_UINT', to represent these timestamps.
3829 This change causes it to use 'Time' uniformly, as that's what X uses.
3830 This makes the code easier to follow, and makes it easier to catch
3831 integer overflow bugs such as Bug#8664.
3832 * frame.c (Fmouse_position, Fmouse_pixel_position):
3833 Use Time, not unsigned long, for user-interface timestamps.
3834 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
3835 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
3836 * keyboard.h (last_event_timestamp): Likewise.
3837 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
3838 * menu.h (xmenu_show): Likewise.
3839 * term.c (term_mouse_position): Likewise.
3840 * termhooks.h (struct input_event.timestamp): Likewise.
3841 (struct terminal.mouse_position_hook): Likewise.
3842 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
3843 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
3844 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
3845 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
3847 * menu.h, termhooks.h: Include "systime.h", for Time.
3849 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
3850 Don't assume that the difference between two unsigned long values
3851 can fit into an integer. At this point, we know button_down_time
3852 <= event->timestamp, so the difference must be nonnegative, so
3853 there's no need to cast the result if double-click-time is
3854 nonnegative, as it should be; check that it's nonnegative, just in
3855 case. This bug is triggered when events are more than 2**31 ms
3856 apart (about 25 days). (Bug#8664)
3858 * xselect.c (last_event_timestamp): Remove duplicate decl.
3859 (x_own_selection): Remove needless cast to unsigned long.
3861 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
3862 that always fit in int. Use a sentinel instead of a counter, to
3863 avoid a temp and to allay GCC's concerns about possible int overflow.
3864 * frame.h (struct frame): Use int for menu_bar_items_used
3865 instead of EMACS_INT, since it always fits in int.
3867 * menu.c (grow_menu_items): Check for int overflow.
3869 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
3871 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
3872 Before, the code was not consistent. These values cannot exceed
3873 2**31 - 1 so there's no need to make them unsigned.
3874 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
3875 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
3876 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
3878 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
3880 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
3881 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
3882 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
3883 presumably because the widths might not match.
3885 * window.c (size_window): Avoid needless test at loop start.
3887 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
3889 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
3891 2011-05-12 Drew Adams <drew.adams@oracle.com>
3893 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
3895 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3897 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
3898 `width' to `bar_area_x' and `bar_area_width', respectively.
3899 (x_scroll_run): Take account of fringe background extension.
3901 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
3902 Rename local vars `left' and `width' to `bar_area_x' and
3903 `bar_area_width', respectively.
3904 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
3905 background extension.
3907 2011-05-10 Jim Meyering <meyering@redhat.com>
3909 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
3911 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
3913 * image.c (Finit_image_library): Return t for built-in image types,
3914 like pbm and xbm. (Bug#8640)
3916 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
3918 * w32menu.c (set_frame_menubar): Fix submenu allocation.
3920 2011-05-07 Eli Zaretskii <eliz@gnu.org>
3922 * w32console.c (Fset_screen_color): Doc fix.
3923 (Fget_screen_color): New function.
3924 (syms_of_ntterm): Defsubr it.
3926 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
3927 unlink the temporary file if Fcall_process didn't create it in the
3929 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
3930 child process will be redirected to a file specified with `:file'.
3931 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
3932 cue to call_process_cleanup not to close that handle.
3934 2011-05-07 Ben Key <bkey76@gmail.com>
3936 * makefile.w32-in: The bootstrap-temacs rule now makes use of
3937 one of two shell specific rules, either bootstrap-temacs-CMD or
3938 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
3939 to the previous implementation of the bootstrap-temacs rule.
3940 The bootstrap-temacs-CMD rule is similar to the previous
3941 implementation of the bootstrap-temacs rule except that it
3942 makes use of the ESC_CFLAGS variable instead of the CFLAGS
3945 These changes, along with some changes to nt/configure.bat,
3946 nt/gmake.defs, and nt/nmake.defs, are required to extend my
3947 earlier fix to add support for --cflags and --ldflags options
3948 that include quotes so that it works whether make uses cmd or
3951 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
3953 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
3954 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
3956 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
3957 a string. Handle both cases.
3958 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
3959 (Fdbus_register_method): Use Qinvalid_function.
3961 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3963 * makefile.w32-in: Update dependencies.
3964 (LISP_H): Add inttypes.h and stdin.h.
3965 (PROCESS_H): Add unistd.h.
3967 2011-05-06 Eli Zaretskii <eliz@gnu.org>
3969 * lread.c: Include limits.h (fixes the MS-Windows build broken by
3970 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
3972 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
3974 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
3976 * term.c (vfatal): Remove stray call to va_end.
3977 It's not needed and the C Standard doesn't allow it here anyway.
3979 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
3980 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
3982 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
3985 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
3987 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3989 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
3991 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
3993 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
3995 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
3996 * charset.c (Fdefine_charset_internal): Don't initialize
3997 charset.code_space[15]. The value was garbage, on hosts with
3998 32-bit int (Bug#8600).
4000 * lread.c (read_integer): Be more consistent with string-to-number.
4001 Use string_to_number to do the actual conversion; this avoids
4002 rounding errors and fixes some other screwups. Without this fix,
4003 for example, #x1fffffffffffffff was misread as -2305843009213693952.
4004 (digit_to_number): Move earlier, for benefit of read_integer.
4005 Return -1 if the digit is out of range for the base, -2 if it is
4006 not a digit in any supported base. (Bug#8602)
4008 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
4010 * dispnew.c (scrolling_window): Return 1 if we scrolled,
4011 to match comment at start of function. This also removes a
4012 GCC warning about overflow in a 32+64-bit port.
4014 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
4016 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
4017 Reported by Stefan Monnier in
4018 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
4019 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
4020 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
4022 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
4023 (EMACS_UINTPTR): Likewise, with uintptr_t.
4025 * lisp.h: Prefer 64-bit EMACS_INT if available.
4026 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
4027 on 32-bit hosts that have 64-bit int, so that they can access
4029 However, temporarily disable this change unless the temporary
4030 symbol WIDE_EMACS_INT is defined.
4032 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
4034 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
4035 This removes an assumption that EMACS_INT and long are the same
4036 width as pointers. The assumption is true for Emacs porting targets
4037 now, but we want to make other targets possible.
4038 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
4039 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
4040 In the rest of the code, change types of integers that hold casted
4041 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
4042 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
4043 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
4044 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
4045 No need to cast type when ORing.
4046 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
4047 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
4048 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
4049 assume EMACS_INT is the same width as char *.
4050 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
4051 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
4052 Remove no-longer-needed casts.
4053 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
4054 (xg_tool_bar_help_callback, xg_make_tool_item):
4055 Use EMACS_INTPTR to hold an integer
4056 that will be cast to void *; this can avoid a GCC warning
4057 if EMACS_INT is not the same width as void *.
4058 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
4059 * xdisp.c (display_echo_area_1, resize_mini_window_1):
4060 (current_message_1, set_message_1):
4061 Use a local to convert to proper width without a cast.
4062 * xmenu.c (dialog_selection_callback): Likewise.
4064 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
4065 Also, don't assume VALBITS / RAND_BITS is less than 5,
4066 and don't rely on undefined behavior when shifting a 1 left into
4068 * lisp.h (get_random): Change signature to match.
4070 * lread.c (hash_string): Use size_t, not int, for hash computation.
4071 Normally we prefer signed values; but hashing is special, because
4072 it's better to use unsigned division on hash table sizes so that
4073 the remainder is nonnegative. Also, size_t is the natural width
4074 for hashing into memory. The previous code used 'int', which doesn't
4075 retain enough info to hash well into very large tables.
4076 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
4078 * dbusbind.c: Don't possibly lose pointer info when converting.
4079 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
4080 Use XPNTR rather than XHASH, so that the high-order bits of
4081 the pointer aren't lost when converting through void *.
4083 * eval.c (Fautoload): Don't double-shift a pointer.
4085 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
4087 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
4089 * gnutls.c (DEF_GNUTLS_FN):
4090 * image.c (DEF_IMGLIB_FN): Make function pointers static.
4092 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
4094 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
4097 2011-05-05 Eli Zaretskii <eliz@gnu.org>
4099 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
4100 New version that can reserve upto 2GB of heap space.
4102 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
4104 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
4106 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
4108 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
4109 `gnutls_certificate_set_x509_key_file'.
4111 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
4113 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
4114 Update dependencies.
4116 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4118 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
4119 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
4120 Remove unused parameter `fildes'.
4121 * process.c (read_process_output, send_process): Don't pass it.
4123 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4125 Fix previous change: the library cache is defined in w32.c.
4126 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
4127 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
4129 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4131 Implement dynamic loading of GnuTLS on Windows.
4133 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
4134 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
4135 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
4138 * gnutls.c (Qgnutls_dll): Define.
4139 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
4140 (gnutls_*): Declare function pointers.
4141 (init_gnutls_functions): New function to initialize function pointers.
4142 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
4143 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
4144 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
4145 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
4146 (emacs_gnutls_write, emacs_gnutls_read)
4147 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
4148 (Fgnutls_available_p): New function.
4149 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
4150 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
4151 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
4153 * image.c: Include w32.h.
4154 (Vimage_type_cache): Delete.
4155 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
4156 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
4157 (w32_delayed_load): Move to w32.c.
4159 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
4161 * w32.c (QCloaded_from, Vlibrary_cache): Define.
4162 (w32_delayed_load): Move from image.c. When loading a library, record
4163 its filename in the :loaded-from property of the library id.
4164 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:

4217 (Fcall_process_region): Ditto.
4219 2011-04-30 Eli Zaretskii <eliz@gnu.org>
4221 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
4222 rather than `XVECTOR (FOO)->size'.
4224 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
4225 inttypes.h, as a gnulib replacement is used if it not available in

4235 will grow beyond MOST_POSITIVE_FIXNUM.
4236 (decode_coding_emacs_mule): Abort if there isn't enough place in
4237 charbuf for the composition carryover bytes. Reserve an extra
4238 space for up to 2 characters produced in a loop.
4239 (decode_coding_iso_2022): Abort if there isn't enough place in
4240 charbuf for the composition carryover bytes.
4242 2011-04-21 Eli Zaretskii <eliz@gnu.org>

4245 aborting when %lld or %lll format is passed.
4246 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
4247 %llo or %llx format is passed. (Bug#8545)
4249 * window.c (window_scroll_line_based): Use a marker instead of
4250 simple variables to record original value of point. (Bug#7952)
4252 * doprnt.c (doprnt): Fix the case where a multibyte sequence
4253 produced by %s or %c overflows available buffer space. (Bug#8545)
4255 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
4257 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
4258 (SIZE_MAX): Move defn after all includes, as they might #define it.
4260 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4262 * w32.c (init_environment): Warn about defaulting HOME to C:\.
4264 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4266 * keyboard.c (Qdelayed_warnings_hook): Define.
4267 (command_loop_1): Run `delayed-warnings-hook'
4268 if Vdelayed_warnings_list is non-nil.
4269 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
4270 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
4272 2011-04-28 Eli Zaretskii <eliz@gnu.org>
4274 * doprnt.c (doprnt): Don't return value smaller than the buffer
4275 size if the message was truncated. (Bug#8545).
4277 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4279 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

4282 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
4284 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
4286 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
4288 * makefile.w32-in: Update dependencies.
4290 2011-04-27 Eli Zaretskii <eliz@gnu.org>
4292 Improve `doprnt' and its usage. (Bug#8545)
4293 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
4294 `format_end'. Remove support for %l as a conversion specifier.
4295 Don't use xrealloc. Improve diagnostics when the %l size modifier
4296 is used. Update the commentary.
4298 * eval.c (verror): Simplify calculation of size_t.
4300 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
4303 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
4305 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
4308 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
4310 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
4311 This makes this file independent of the recent pseudovector change.
4313 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
4315 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
4317 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
4318 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
4319 Remove unused local.
4320 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
4322 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
4323 GCC 4.6.0 optimizes based on type-based alias analysis.
4324 For example, if b is of type struct buffer * and v of type struct
4325 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
4326 != &v->size, and therefore "v->size = 1; b->size = 2; return
4327 v->size;" must therefore return 1. This assumption is incorrect
4328 for Emacs, since it type-puns struct Lisp_Vector * with many other
4329 types. To fix this problem, this patch adds a new type struct
4330 vectorlike_header that documents the constraints on layout of vectors
4331 and pseudovectors, and helps optimizing compilers not get fooled
4332 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
4333 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
4334 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
4336 (XSETPVECTYPE): Rewrite in terms of new macro.
4337 (XSETPVECTYPESIZE): New macro, specifying both type and size.
4338 This is a bit clearer, and further avoids the possibility of
4339 undesirable aliasing.
4340 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
4341 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
4342 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
4343 since Lisp_Subr is a special case (no "next" field).
4344 (ASIZE): Now uses header.size rather than size.
4345 All previous uses of XVECTOR (foo)->size replaced to use this macro,
4346 to avoid the hassle of writing XVECTOR (foo)->header.size.
4347 (struct vectorlike_header): New type.
4348 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
4349 object, to help avoid aliasing.
4350 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
4351 (SUBRP): Likewise, since Lisp_Subr is a special case.
4352 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
4353 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
4354 (struct Lisp_Hash_Table): Combine first two members into a single
4355 struct vectorlike_header member. All uses of "size" and "next" members
4356 changed to be "header.size" and "header.next".
4357 * buffer.h (struct buffer): Likewise.
4358 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
4359 * frame.h (struct frame): Likewise.
4360 * process.h (struct Lisp_Process): Likewise.
4361 * termhooks.h (struct terminal): Likewise.
4362 * window.c (struct save_window_data, struct saved_window): Likewise.
4363 * window.h (struct window): Likewise.
4364 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
4365 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
4366 * buffer.c (init_buffer_once): Likewise.
4367 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
4369 * process.c (Fformat_network_address): Use local var for size,
4372 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
4374 Make the Lisp reader and string-to-float more consistent (Bug#8525)
4375 * data.c (atof): Remove decl; no longer used or needed.
4376 (digit_to_number): Move to lread.c.
4377 (Fstring_to_number): Use new string_to_number function, to be
4378 consistent with how the Lisp reader treats infinities and NaNs.
4379 Do not assume that floating-point numbers represent EMACS_INT
4380 without losing information; this is not true on most 64-bit hosts.
4381 Avoid double-rounding errors, by insisting on integers when
4382 parsing non-base-10 numbers, as the documentation specifies.
4383 * lisp.h (string_to_number): New decl, replacing ...
4384 (isfloat_string): Remove.
4385 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
4386 (read1): Do not accept +. and -. as integers; this
4387 appears to have been a coding error. Similarly, do not accept
4388 strings like +-1e0 as floating point numbers. Do not report
4389 overflow for integer overflows unless the base is not 10 which
4390 means we have no simple and reliable way to continue.
4391 Break out the floating-point parsing into a new
4392 function string_to_number, so that Fstring_to_number parses
4393 floating point numbers consistently with the Lisp reader.
4394 (digit_to_number): Move here from data.c. Make it static inline.
4395 (E_CHAR, EXP_INT): Remove, replacing with ...
4396 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
4397 (string_to_number): New function, replacing isfloat_string.
4398 This function checks for valid syntax and produces the resulting
4399 Lisp float number too. Rework it so that string-to-number
4400 no longer mishandles examples like "1.0e+". Use strtoumax,
4401 so that overflow for non-base-10 numbers is reported only when
4402 there's no portable and simple way to convert to floating point.
4404 * textprop.c (set_text_properties_1): Rewrite for clarity,
4405 and to avoid GCC warning about integer overflow.
4407 * intervals.h (struct interval): Use EMACS_INT for members
4408 where EMACS_UINT might cause problems. See
4409 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
4410 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
4411 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
4413 (offset_intervals): Tell GCC not to worry about length overflow
4414 when negating a negative length.
4416 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
4417 (overrun_check_free): Likewise.
4419 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
4420 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
4423 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4424 (gnutls_make_error): Rename local to avoid shadowing.
4425 (gnutls_emacs_global_deinit): ifdef out; not used.
4426 (Fgnutls_boot): Use const for pointer to readonly storage.
4427 Comment out unused local. Fix pointer signedness problems.
4429 * lread.c (openp): Don't stuff size_t into an 'int'.
4430 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
4431 about possible signed overflow.
4433 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4434 (GDK_KEY_g): Don't define if already defined.
4435 (xg_prepare_tooltip): Avoid pointer signedness problem.
4436 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
4438 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
4439 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
4441 * xfns.c (Fx_window_property): Simplify a bit,
4442 to make a bit faster and to avoid GCC 4.6.0 warning.
4443 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
4445 * fns.c (internal_equal): Don't assume size_t fits in int.
4447 * alloc.c (compact_small_strings): Tighten assertion a little.
4449 Replace pEd with more-general pI, and fix some printf arg casts.
4450 * lisp.h (pI): New macro, generalizing old pEd macro to other
4451 conversion specifiers. For example, use "...%"pI"d..." rather
4452 than "...%"pEd"...".
4453 (pEd): Remove. All uses replaced with similar uses of pI.
4454 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
4455 * alloc.c (check_pure_size): Don't overflow by converting size to int.
4456 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
4457 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
4458 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
4459 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
4460 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
4462 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
4463 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
4464 * print.c (safe_debug_print, print_object): Likewise.
4465 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
4467 Use pI instead of if-then-else-abort. Use %p to avoid casts,
4468 avoiding the 0 flag, which is not portable.
4469 * process.c (Fmake_network_process): Use pI to avoid cast.
4470 * region-cache.c (pp_cache): Likewise.
4471 * xdisp.c (decode_mode_spec): Likewise.
4472 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
4473 behavior on 64-bit hosts with printf arg.
4474 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
4475 (x_stop_queuing_selection_requests): Likewise.
4476 (x_get_window_property): Don't truncate byte count to an 'int'
4479 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
4480 here, since it parses constructs like leading '-' and spaces,
4481 which are not wanted; and it overflows with large numbers.
4482 Instead, simply match F[0-9]+, which is what is wanted anyway.
4484 * alloc.c: Remove unportable assumptions about struct layout.
4485 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
4486 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
4487 (allocate_vectorlike, make_pure_vector): Use the new macros,
4488 plus offsetof, to remove unportable assumptions about struct layout.
4489 These assumptions hold on all porting targets that I know of, but
4490 they are not guaranteed, they're easy to remove, and removing them
4491 makes further changes easier.
4493 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
4494 This doesn't fix a bug but makes the code clearer.
4495 (string_overrun_cookie): Now const. Use initializers that
4496 don't formally overflow signed char, to avoid warnings.
4497 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
4498 can cause Emacs to crash when string overrun checking is enabled.
4499 (allocate_buffer): Don't assume sizeof (struct buffer) is a
4500 multiple of sizeof (EMACS_INT); it need not be, if
4501 alignof(EMACS_INT) < sizeof (EMACS_INT).
4502 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
4504 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

4524 * alloc.c (check_sblock, check_string_bytes)
4525 (check_string_free_list): Convert to standard C.
4527 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
4529 * w32.c (emacs_gnutls_push): Fix typo.
4531 2011-04-25 Eli Zaretskii <eliz@gnu.org>
4533 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
4534 "cast to pointer from integer of different size".
4536 Improve doprnt and its use in verror. (Bug#8545)
4537 * doprnt.c (doprnt): Document the set of format control sequences
4538 supported by the function. Use SAFE_ALLOCA instead of always
4541 * eval.c (verror): Don't limit the buffer size at size_max-1, that
4542 is one byte too soon. Don't use xrealloc; instead xfree and
4545 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
4547 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
4550 * gnutls.c: Renamed global_initialized to
4551 gnutls_global_initialized. Added internals for the
4552 :verify-hostname-error, :verify-error, and :verify-flags
4553 parameters of `gnutls-boot' and documented those parameters in the
4554 docstring. Start callback support.
4555 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
4556 unless a fatal error occurred. Call gnutls_alert_send_appropriate
4557 on error. Return error code.
4558 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
4559 (emacs_gnutls_read): Likewise.
4560 (Fgnutls_boot): Return handshake error code.
4561 (emacs_gnutls_handle_error): New function.
4562 (wsaerror_to_errno): Likewise.
4564 * w32.h (emacs_gnutls_pull): Add prototype.
4565 (emacs_gnutls_push): Likewise.
4567 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
4568 (emacs_gnutls_push): Likewise.
4570 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
4572 * process.c (wait_reading_process_output): Check if GnuTLS
4573 buffered some data internally if no FDs are set for TLS

4577 (LIBS): Link to USER_LIBS.
4578 ($(BLD)/gnutls.$(0)): New target.
4580 2011-04-24 Eli Zaretskii <eliz@gnu.org>
4582 * xdisp.c (handle_single_display_spec): Rename the
4583 display_replaced_before_p argument into display_replaced_p, to

4736 Define only if needed.
4738 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier

5110 * editfns.c, lisp.h (get_operating_system_release): Remove.
5111 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
5112 worth the hassle of breaking this out.
5114 * xterm.c: Make symbols static if they're not exported.
5115 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

5221 so that it's not optimized away.
5222 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
5223 * dispextern.h (bidi_dump_cached_states): Remove, since it's
5224 exported only to the debugger.
5226 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
5227 * atimer.h (run_all_atimers): Remove; not exported.
5229 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
5230 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
5231 was inaccessible from Lisp.
5232 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
5233 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
5235 alloc.c: Import and export fewer symbols, and remove unused items.
5236 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
5238 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
5239 it's not optimized away by whole-program optimization.

5247 (n_float_blocks, float_free_list, cons_block, cons_block_index):
5248 (cons_free_list, last_marked_index):

5251 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
5252 (mark_backtrace): Define only if BYTE_MARK_STACK.
5253 * xdisp.c (message_enable_multibyte): Now static.
5255 Declare Lisp_Object Q* variables to be 'static' if not exported.
5256 This makes it easier for human readers (and static analyzers)
5257 to see whether these variables are used from other modules.
5258 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
5259 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

5267 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
5268 Remove decls of unexported vars.
5269 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
5271 * lisp.h (DEFINE_FUNC): Make sname 'static'.
5273 Make Emacs functions such as Fatom 'static' by default.
5274 This makes it easier for human readers (and static analyzers)
5275 to see whether these functions can be called from other modules.
5276 DEFUN now defines a static function. To make the function external
5277 so that it can be used in other C modules, use the new macro DEFUE.
5278 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
5279 (Finit_image_library):
5280 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
5281 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
5282 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
5283 Remove decls, since these functions are now static.
5284 (Funintern, Fget_internal_run_time): New decls, since these functions
5285 were already external.
5287 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
5288 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

5293 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
5294 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
5295 Mark functions with DEFUE instead of DEFUN,
5296 if they are used in other modules.
5297 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
5298 decls for now-static functions.
5299 * buffer.h (Fdelete_overlay): Remove decl.

5330 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
5332 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
5335 2011-04-13 Eli Zaretskii <eliz@gnu.org>
5337 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
5338 when at ZV. (Bug#8487)
5340 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
5342 * charset.c (Fclear_charset_maps): Use xfree instead of free.
5344 * keyboard.c (parse_tool_bar_item): Likewise.
5345 * sound.c (sound_cleanup, alsa_close): Likewise.
5346 * termcap.c (tgetent): Likewise.
5347 * xfns.c (x_default_font_parameter): Likewise.
5348 * xsettings.c (read_and_apply_settings): Likewise.
5350 * alloc.c (overrun_check_malloc, overrun_check_realloc)
5351 (overrun_check_free): Protoize.
5353 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
5355 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
5356 since callers should never pass a negative size.
5357 Change the signature to match that of plain 'read' and 'write'; see
5358 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
5359 * lisp.h: Update prototypes of emacs_write and emacs_read.
5361 2011-04-11 Eli Zaretskii <eliz@gnu.org>
5363 * xdisp.c (redisplay_window): Don't try to determine the character
5364 position of the scroll margin if the window start point w->startp
5365 is outside the buffer's accessible region. (Bug#8468)
5367 2011-04-10 Eli Zaretskii <eliz@gnu.org>
5369 Fix write-region and its subroutines for buffers > 2GB.
5370 * fileio.c (a_write, e_write): Modify declaration of arguments and
5371 local variables to support buffers larger than 2GB.
5372 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
5374 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
5375 argument, local variables, and return value.
5377 * lisp.h: Update prototypes of emacs_write and emacs_read.
5379 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
5381 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
5383 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
5385 Fix more problems found by GCC 4.6.0's static checks.
5387 * xdisp.c (vmessage): Use a better test for character truncation.
5389 * charset.c (load_charset_map): <, not <=, for optimization,
5390 and to avoid potential problems with integer overflow.
5391 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
5392 * casetab.c (set_identity, shuffle): Likewise.
5393 * editfns.c (Fformat): Likewise.
5394 * syntax.c (skip_chars): Likewise.
5396 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
5397 This also lets GCC 4.6.0 generate slightly better loop code.
5399 * callint.c (Fcall_interactively): <, not <=, for optimization.
5400 (Fcall_interactively): Count the number of arguments produced,
5401 not the number of arguments given. This is simpler and lets GCC
5402 4.6.0 generate slightly better code.
5404 * ftfont.c: Distingish more carefully between FcChar8 and char.
5405 The previous code passed unsigned char * to a functions like
5406 strlen and xstrcasecmp that expect char *, which does not
5407 conform to the C standard.
5408 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
5409 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
5410 char * when the C standard requires it.
5412 * keyboard.c (read_char): Remove unused var.
5414 * eval.c: Port to Windows vsnprintf (Bug#8435).
5416 (SIZE_MAX): Define if the headers do not.
5417 (verror): Do not give up if vsnprintf returns a negative count.
5418 Instead, grow the buffer. This ports to Windows vsnprintf, which
5419 does not conform to C99. Problem reported by Eli Zaretskii.
5420 Also, simplify the allocation scheme, by avoiding the need for
5421 calling realloc, and removing the ALLOCATED variable.
5423 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
5425 Remove invocations of doprnt, as Emacs now uses vsnprintf.
5426 But keep the doprint source code for now, as we might revamp it
5427 and use it again (Bug#8435).
5428 * lisp.h (doprnt): Remove.
5429 * Makefile.in (base_obj): Remove doprnt.o.
5430 * deps.mk (doprnt.o): Remove.
5432 error: Print 32- and 64-bit integers portably (Bug#8435).
5433 Without this change, on typical 64-bit hosts error ("...%d...", N)
5434 was used to print both 32- and 64-bit integers N, which relied on
5436 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
5438 * lisp.h (error, verror): Mark as printf-like functions.
5439 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
5440 Report overflow in size calculations when allocating printf buffer.
5441 Do not truncate output string at its first null byte.
5442 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
5443 Truncate the output at a character boundary, since vsnprintf does not
5445 * charset.c (check_iso_charset_parameter): Convert internal
5446 character to string before calling 'error', since %c now has the
5448 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
5449 overflow when computing char to be passed to 'error'. Do not
5450 pass Lisp_Object to 'error'; pass the integer instead.
5451 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
5452 formatted with plain %d.
5454 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
5456 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
5458 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
5460 * xterm.c (x_catch_errors): Remove duplicate declaration.
5462 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
5464 * xdisp.c, lisp.h (message_nolog): Remove; unused.
5466 2011-04-10 Jim Meyering <meyering@redhat.com>
5468 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
5469 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
5470 return ssize_t not "int", and use size_t as the buffer length.
5471 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
5472 * gnutls.h: Update declarations.
5473 * process.c (read_process_output): Use ssize_t, to match.
5474 (send_process): Likewise.
5476 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
5478 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
5480 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
5482 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
5483 Use unsigned char, to match FcChar8 type definition.
5485 * xterm.c (handle_one_xevent):
5486 * xmenu.c (create_and_show_popup_menu):
5487 * xselect.c (x_decline_selection_request)
5488 (x_reply_selection_request): Avoid type-punned deref of X events.
5490 2011-04-09 Eli Zaretskii <eliz@gnu.org>
5492 Fix some uses of `int' instead of EMACS_INT.
5493 * search.c (string_match_1, fast_string_match)
5494 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
5495 (scan_buffer, find_next_newline_no_quit)
5496 (find_before_next_newline, search_command, Freplace_match)
5497 (Fmatch_data): Make some `int' variables be EMACS_INT.
5499 * xdisp.c (display_count_lines): 3rd argument and return value now
5500 EMACS_INT. All callers changed.
5501 (pint2hrstr): Last argument is now EMACS_INT.
5503 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
5504 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

5517 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
5519 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
5520 (encode_invocation_designation): Last argument P_NCHARS is now
5522 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
5523 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
5525 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
5528 * ccl.c (Fccl_execute_on_string): Declare some variables
5531 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

5546 instead of using internal_with_output_to_temp_buffer.
5547 (Qhelp_form_show): New var.
5548 (syms_of_keyboard): Use DEFSYM macro.
5550 * print.c (internal_with_output_to_temp_buffer): Function deleted.
5552 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
5554 2011-04-06 Chong Yidong <cyd@stupidchicken.com>

5565 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
5567 Fix more problems found by GCC 4.6.0's static checks.
5569 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
5571 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
5573 * lisp.h (message, message_nolog, fatal): Mark as printf-like.

5586 * eval.c (Fsignal): Remove excess argument to 'fatal'.
5588 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
5589 This avoids several warnings with gcc -Wstrict-overflow.
5590 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
5591 directly, rather than having caller test rule sign. This avoids
5592 some unnecessary tests.
5593 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
5594 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
5595 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
5597 * xfont.c (xfont_text_extents): Remove var that was set but not used.
5598 (xfont_open): Avoid unnecessary tests.
5600 * composite.c (composition_gstring_put_cache): Use unsigned integer.
5602 * composite.h, composite.c (composition_gstring_put_cache):
5603 Use EMACS_INT, not int, for length.
5605 * composite.h (COMPOSITION_DECODE_REFS): New macro,
5606 breaking out part of COMPOSITION_DECODE_RULE.
5607 (COMPOSITION_DECODE_RULE): Use it.
5608 * composite.c (get_composition_id): Remove unused local vars,
5609 by using the new macro.
5611 * textprop.c (set_text_properties_1): Change while to do-while,
5612 since the condition is always true at first.
5614 * intervals.c (graft_intervals_into_buffer): Mark var as used.
5615 (interval_deletion_adjustment): Return unsigned value.
5618 * process.c (list_processes_1, create_pty, read_process_output):

5620 (create_pty): Remove unnecessary "volatile"s.
5621 (Fnetwork_interface_info): Avoid possibility of int overflow.
5622 (read_process_output): Do adaptive read buffering even if carryover.
5623 (read_process_output): Simplify nbytes computation if buffered.

5627 * syntax.c (scan_words): Remove var that was set but not used.
5628 (update_syntax_table): Use unsigned instead of int.

5637 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
5639 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
5640 (font_score): Avoid potential overflow in diff calculation.
5642 * fns.c (substring_both): Remove var that is set but not used.
5643 (sxhash): Redo loop for clarity and to avoid wraparound warning.
5645 * eval.c (funcall_lambda): Rename local to avoid shadowing.
5647 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
5648 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
5649 can always succeed if overflow has undefined behavior.
5651 * search.c (boyer_moore, wordify): Remove vars set but not used.
5652 (wordify): Omit three unnecessary tests.
5654 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
5655 All callers changed. This avoids the need for an unused var.
5657 * casefiddle.c (casify_region): Remove var that is set but not used.
5659 * dired.c (file_name_completion): Remove var that is set but not used.
5661 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
5663 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
5664 (Finsert_file_contents): Remove unnecessary code checking fd.
5666 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
5667 Check for integer overflow on size calculations.
5669 * buffer.c (Fprevious_overlay_change): Remove var that is set
5672 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
5673 Remove vars that are set but not used.
5674 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
5675 (timer_check_2): Mark vars as initialized.
5677 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
5679 * image.c (lookup_image): Remove var that is set but not used.
5680 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
5682 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
5683 that are set but not used.
5685 * xfns.c (make_invisible_cursor): Don't return garbage
5686 if XCreateBitmapFromData fails (Bug#8410).
5688 * xselect.c (x_get_local_selection, x_handle_property_notify):
5689 Remove vars that are set but not used.
5691 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
5692 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
5694 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
5695 Remove var that is set but not used.
5696 (scroll_bar_windows_size): Now size_t, not int.
5697 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
5700 * xfaces.c (realize_named_face): Remove vars that are set but not used.
5701 (map_tty_color) [!defined MSDOS]: Likewise.
5703 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
5705 * coding.c: Remove vars that are set but not used.
5706 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
5707 All callers changed.
5708 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
5709 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
5710 (decode_coding_charset): Remove vars that are set but not used.
5712 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
5713 that is set but not used.
5715 * print.c (print_object): Remove var that is set but not used.
5717 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
5718 The gnulib version avoids calling malloc in the usual case,
5719 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
5720 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
5721 * filelock.c (current_lock_owner): Likewise.
5722 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
5723 * sysdep.c: Include allocator.h, careadlinkat.h.
5724 (emacs_no_realloc_allocator): New static constant.
5725 (emacs_readlink): New function.
5726 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
5727 ../lib/careadlinkat.h.
5729 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
5731 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
5732 first non-nil return value).
5734 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
5736 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
5737 if not defined (Bug#8403).
5739 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
5741 * xdisp.c (display_count_lines): Remove parameter `start',
5742 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5743 (get_char_face_and_encoding): Remove parameter `multibyte_p',
5744 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

5746 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
5747 and thereabouts. All callers changed.
5748 (get_per_char_metric): Remove parameter `f', unused since
5749 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
5751 2011-04-02 Jim Meyering <meyering@redhat.com>
5753 do not dereference NULL upon failed strdup
5754 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
5755 (ns_get_family): Likewise.
5757 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
5759 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
5761 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
5763 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
5766 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
5768 Add lexical binding.
5770 * window.c (Ftemp_output_buffer_show): New fun.
5771 (Fsave_window_excursion):
5772 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
5774 * lread.c (lisp_file_lexically_bound_p): New function.
5775 (Fload): Bind Qlexical_binding.
5776 (readevalloop): Remove `evalfun' arg.
5777 Bind Qinternal_interpreter_environment.
5778 (Feval_buffer): Bind Qlexical_binding.
5779 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
5781 (syms_of_lread): Declare `lexical-binding'.
5783 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
5785 * keyboard.c (eval_dyn): New fun.
5786 (menu_item_eval_property): Use it.
5788 * image.c (parse_image_spec): Use Ffunctionp.
5790 * fns.c (concat, mapcar1): Accept byte-code-functions.
5792 * eval.c (Fsetq): Handle lexical vars.
5793 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
5794 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
5795 (FletX, Flet): Obey lexical binding.
5796 (Fcommandp): Handle closures.
5797 (Feval): New `lexical' arg.
5798 (eval_sub): New function extracted from Feval. Use it almost
5799 everywhere where Feval was used. Look up vars in lexical env.
5801 (Ffunctionp): Move from subr.el.
5802 (Ffuncall): Handle closures.
5803 (apply_lambda): Remove `eval_flags'.
5804 (funcall_lambda): Handle closures and new byte-code-functions.
5805 (Fspecial_variable_p): New function.
5806 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
5807 but without exporting it to Lisp.
5809 * doc.c (Fdocumentation, store_function_docstring):
5810 * data.c (Finteractive_form): Handle closures.
5812 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
5815 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
5817 (exec_byte_code): New function extracted from Fbyte_code to handle new
5818 calling convention for byte-code-functions. Add new byte-codes.
5820 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
5822 * alloc.c (Fmake_symbol): Init new `declared_special' field.
5824 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
5826 * xdisp.c (redisplay_internal): Fix prototype.
5828 2011-03-31 Eli Zaretskii <eliz@gnu.org>
5830 * xdisp.c (SCROLL_LIMIT): New macro.
5831 (try_scrolling): Use it when setting scroll_limit.
5832 Limit scrolling to 100 screen lines.
5833 (redisplay_window): Even when falling back on "recentering",
5834 position point in the window according to scroll-conservatively,
5835 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
5837 (try_scrolling): When point is above the window, allow searching
5838 as far as scroll_max, or one screenful, to compute vertical
5839 distance from PT to the scroll margin position. This prevents
5840 try_scrolling from unnecessarily failing when
5841 scroll-conservatively is set to a value slightly larger than the
5842 window height. Clean up the case of PT below the margin at bottom
5843 of window: scroll_max can no longer be INT_MAX. When aggressive
5844 scrolling is in use, don't let point enter the opposite scroll
5845 margin as result of the scroll.
5846 (syms_of_xdisp) <scroll-conservatively>: Document the
5847 threshold of 100 lines for never-recentering scrolling.
5849 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
5851 * dispextern.h (move_it_by_lines):
5852 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
5853 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
5854 (message_log_check_duplicate): Remove parameters `prev_bol' and
5855 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5856 (redisplay_internal): Remove parameter `preserve_echo_area',
5857 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
5859 * indent.c (Fvertical_motion):
5860 * window.c (window_scroll_pixel_based, Frecenter):
5861 Don't pass `need_y_p' to `move_it_by_lines'.
5863 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
5865 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
5866 steal a few bits to be more compact.
5867 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
5868 Remove unneeded casts.
5870 * bytecode.c (Fbyte_code): CAR and CDR can GC.
5872 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
5874 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
5875 binding" message (bug#7967).
5877 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
5879 Fix more problems found by GCC 4.6.0's static checks.
5881 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
5882 Remove unused local var.
5884 * editfns.c (Fmessage_box): Remove unused local var.
5886 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
5887 (note_mode_line_or_margin_highlight, note_mouse_highlight):
5888 Omit unused local vars.
5889 * window.c (shrink_windows): Omit unused local var.
5890 * menu.c (digest_single_submenu): Omit unused local var.
5891 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
5892 Omit unused local var.
5894 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
5895 Don't assume string length fits in int.
5896 (keyremap_step, read_key_sequence): Use size_t for sizes.
5897 (read_key_sequence): Don't check last_real_key_start redundantly.
5899 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
5900 instead of alloca (Bug#8344).
5902 * eval.c (Fbacktrace): Don't assume nargs fits in int.
5903 (Fbacktrace_frame): Don't assume nframes fits in int.
5905 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
5907 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
5910 * term.c (produce_glyphless_glyph): Remove unnecessary test.
5912 * cm.c (calccost): Turn while-do into do-while, for clarity.
5914 * keyboard.c (syms_of_keyboard): Use the same style as later
5915 in this function when indexing through an array. This also
5916 works around GCC bug 48267.
5918 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
5920 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
5922 * chartab.c (sub_char_table_ref_and_range): Redo for slight
5923 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
5925 * keyboard.c, keyboard.h (num_input_events): Now size_t.
5926 This avoids undefined behavior on integer overflow, and is a bit
5927 more convenient anyway since it is compared to a size_t variable.
5929 Variadic C functions now count arguments with size_t, not int.
5930 This avoids an unnecessary limitation on 64-bit machines, which
5931 caused (substring ...) to crash on large vectors (Bug#8344).
5932 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
5933 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

5940 (funcall_lambda, mark_backtrace): Likewise.
5941 * fns.c (concat): Likewise.
5942 * frame.c (x_set_frame_parameters): Likewise.
5943 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
5944 0 if not found, not -1. All callers changed.
5946 * alloc.c (garbage_collect): Don't assume stack size fits in int.
5947 (stack_copy_size): Now size_t, not int.
5948 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
5950 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
5952 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
5953 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
5954 All callers changed.
5956 * lisp.h (multibyte_char_to_unibyte):
5957 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
5958 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
5959 * character.h (CHAR_TO_BYTE8):
5960 * cmds.c (internal_self_insert):
5961 * editfns.c (general_insert_function):
5962 * keymap.c (push_key_description):
5963 * search.c (Freplace_match):
5964 * xdisp.c (message_dolog, set_message_1): All callers changed.
5966 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5968 * keyboard.c (safe_run_hook_funcall): New function.
5969 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
5970 don't set the hook to nil, but remove the offending function instead.
5971 (Qcommand_hook_internal): Remove, unused.
5972 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
5973 Vcommand_hook_internal.
5975 * eval.c (enum run_hooks_condition): Remove.
5976 (funcall_nil, funcall_not): New functions.
5977 (run_hook_with_args): Call each function through a `funcall' argument.
5978 Remove `cond' argument, now redundant.
5979 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)

5987 * print.c (strout): Remove parameter `multibyte', unused since
5988 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
5990 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
5991 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
5992 All callers changed.
5994 * w32.c (_wsa_errlist): Use braces for struct initializers.
5996 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
5997 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
5998 All callers changed.
5999 (string_buffer_position): Likewise. Also, make static (it's never
6000 used outside xdisp.c).
6001 (cursor_row_p): Remove parameter `w', unused since
6002 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

6154 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
6156 (command_loop_1): Use Frun_hooks. Call safe_run_hooks

6159 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
6161 Fix more problems found by GCC 4.5.2's static checks.
6163 * coding.c (encode_coding_raw_text): Avoid unnecessary test
6164 the first time through the loop, since we know p0 < p1 then.
6165 This also avoids a gcc -Wstrict-overflow warning.
6167 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
6168 leading to a memory leak, possible in functions like
6169 load_charset_map_from_file that can allocate an unbounded number
6170 of objects (Bug#8318).
6172 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
6173 that could (at least in theory) be that large.
6175 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
6176 This is less likely to overflow, and avoids undefined behavior if
6177 overflow does occur. All callers changed. Use strtoul to scan

6188 This also avoids a warning with gcc -Wstrict-overflow.
6190 * fileio.c (Fcopy_file): Report error if fchown or fchmod
6193 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
6195 * process.c (Fmake_network_process): Use socklen_t, not int,
6196 where POSIX says socklen_t is required in portable programs.
6197 This fixes a porting bug on hosts like 64-bit HP-UX, where
6198 socklen_t is wider than int (Bug#8277).
6199 (Fmake_network_process, server_accept_connection):
6200 (wait_reading_process_output, read_process_output):

6213 Make tparam.h and terminfo.c consistent.
6214 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
6215 Include tparam.h instead, since it declares them.
6216 * cm.h (PC): Remove extern decl; tparam.h now does this.
6217 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
6218 * terminfo.c: Include tparam.h, to check interfaces.
6219 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
6220 (tparam): Adjust signature to match interface in tparam.h;
6221 this removes some undefined behavior. Check that outstring and len
6222 are zero, which they always are with Emacs.
6223 * tparam.h (PC, BC, UP): New extern decls.
6225 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
6226 (xftfont_open): Rename locals to avoid shadowing.
6228 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

6246 with a FIXME (Bug#8290).
6248 character.h: Rename locals to avoid shadowing.

6251 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
6252 (BUF_DEC_POS): Be more systematic about renaming local temporaries
6255 * textprop.c (property_change_between_p): Remove; unused.
6257 * intervals.c (interval_start_pos): Now static.

6262 Rename locals to avoid shadowing.
6264 * sound.c (wav_play, au_play, Fplay_sound_internal):
6265 Fix pointer signedness.
6266 (alsa_choose_format): Remove unused local var.
6267 (wav_play): Initialize a variable to 0, to prevent undefined
6268 behavior (Bug#8278).
6270 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
6272 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
6274 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
6275 clobbering (Bug#8298).
6276 * sysdep.c (sys_subshell): Likewise.
6277 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
6279 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
6280 This should get cleaned up, so that child_setup has the
6281 same signature on all platforms.
6283 * callproc.c (call_process_cleanup): Now static.
6284 (relocate_fd): Rename locals to avoid shadowing.
6286 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
6288 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
6289 not to be necessary, and produces flickering.
6291 2011-03-20 Glenn Morris <rgm@gnu.org>
6293 * config.in: Remove file.
6295 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

6298 are now in src/globals.h.
6299 (syms_of_minibuf): Remove spurious & from previous change.
6301 2011-03-20 Leo <sdl.web@gmail.com>
6303 * minibuf.c (completing-read-function): New variable.

6310 Read color file from absolute filename (bug#8250).
6312 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
6314 * makefile.w32-in: Update dependencies.
6316 2011-03-17 Eli Zaretskii <eliz@gnu.org>
6318 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

6339 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
6340 Define only if needed.
6342 * unexelf.c (unexec): Name an expression,
6343 to avoid gcc -Wbad-function-cast warning.
6344 Use a different way to cause a compilation error if anyone uses
6345 n rather than nn, a way that does not involve shadowing.
6346 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
6348 * deps.mk (unexalpha.o): Remove; unused.
6350 New file unexec.h, the (simple) interface for unexec (Bug#8267).

6436 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
6437 Rename locals to avoid shadowing.
6438 (mark_stack): Move local variables into the #ifdef region where

6452 Use functions, not macros, for up- and down-casing (Bug#8254).
6453 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6454 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
6455 to use the following functions instead of these macros.
6456 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
6457 EMACS_INT, since callers assume the returned value fits in int.

6471 (RETALLOC_IF): Define only if needed.
6472 (WORDCHAR_P): Likewise. This one is never needed, but is used
6473 only in a comment talking about a compiler bug, so put inside

6512 Rename locals to avoid shadowing.
6514 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

6518 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
6519 * buffer.h: ... to here, because these macros use current_buffer,

6566 * buffer.c (fix_overlays_before): Mark locals as initialized.
6567 (fix_start_end_in_overlays): Likewise. This function should be
6568 simplified by using pointers-to-pointers, but that's a different

6939 (decode_coding_emacs_mule): Mark variables that gcc
6940 -Wuninitialized does not deduce are never used uninitialized.
6941 (detect_coding_iso_2022): Initialize a local variable that might
6942 be used uninitialized. Leave a FIXME because it's not clear that
6943 this initialization is needed. (Bug#8211)
