3 Avoid the use of snprintf.
4 * font.c (APPEND_SNPRINTF): Remove.
6 * xterm.c (x_io_error_quitter):
7 Use esnprintf, not snprintf. That way, we don't have to worry
8 about porting to ancient platforms that lack snprintf.
9 (x_term_init): Use sprintf, not snprintf.
11 2011-08-30 Paul Eggert <eggert@cs.ucla.edu>
13 sprintf-related integer and memory overflow issues (Bug#9412).
15 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16 (esprintf, esnprintf, exprintf, evxprintf): New functions.
17 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
18 (cmd_error): kbd macro iterations count is now EMACS_INT, not int.
19 (modify_event_symbol): Do not assume that the length of
20 name_alist_or_stem is safe to alloca and fits in int.
21 (Fexecute_extended_command): Likewise for function name and binding.
22 (Frecursion_depth): Wrap around reliably on integer overflow.
23 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
24 since some callers pass EMACS_INT values.
25 (Fsingle_key_description): Don't crash if symbol name contains more
26 than MAX_ALLOCA bytes.
27 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
28 (get_minibuffer): Arg is now EMACS_INT, not int.
29 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
30 (esprintf, esnprintf, exprintf, evxprintf): New decls.
31 * window.h (command_loop_level, minibuf_level): Reflect API changes.
33 * dbusbind.c (signature_cat): New function.
34 (xd_signature, Fdbus_register_signal):
35 Do not overrun buffer; instead, report string overflow.
37 * dispnew.c (add_window_display_history): Don't overrun buffer.
38 Truncate instead; this is OK since it's just a log.
40 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
41 even if the time zone offset is outlandishly large.
42 Don't mishandle offset == INT_MIN.
44 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
45 when creating daemon; the previous buffer-overflow check was incorrect.
47 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
48 which has the guts of the old verror function.
50 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
51 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
53 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
54 (font_unparse_xlfd): Don't blindly alloca long strings.
55 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
56 fits in int, when using sprintf. Use single snprintf to count
57 length of string rather than counting it via multiple sprintfs;
58 that's simpler and more reliable.
59 (APPEND_SPRINTF): New macro.
60 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
61 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
62 sprintf, in case result does not fit in int.

65 (fontset_from_font): Print it.
67 * frame.c (tty_frame_count): Now printmax_t, not int.
68 (make_terminal_frame, set_term_frame_name): Print it.
69 (x_report_frame_params): In X, window IDs are unsigned long,
70 not signed long, so print them as unsigned.
71 (validate_x_resource_name): Check for implausibly long names,
72 and don't assume name length fits in 'int'.
73 (x_get_resource_string): Don't blindly alloca invocation name;
74 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
77 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
78 (xg_check_special_colors, xg_set_geometry):
79 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
81 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
82 Use esprintf, not sprintf, in case result does not fit in int.
84 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
85 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
86 it as a large positive number.
87 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
88 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
90 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
91 in case result does not fit in int.
93 * print.c (float_to_string): Detect width overflow more reliably.
94 (print_object): Make sprintf buffer a bit bigger, to avoid potential
95 buffer overrun. Don't assume list length fits in 'int'. Treat
96 print length of 0 as 0, not as infinity; to be consistent with other
97 uses of print length in this function. Don't overflow print length
98 index. Don't assume hash table size fits in 'long', or that
99 vectorlike size fits in 'unsigned long'.
101 * process.c (make_process): Use printmax_t, not int, to format
102 process-name gensyms.
104 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
105 to avoid potential buffer overrun.
107 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
108 if X resource line is longer than 512 bytes.
110 * xfns.c (x_window): Make sprintf buffer a bit bigger
111 to avoid potential buffer overrun.
113 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
115 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
117 2011-08-30 Eli Zaretskii <eliz@gnu.org>
119 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
121 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
122 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
123 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
125 * term.c (tty_append_glyph): New function.
126 (produce_stretch_glyph): Static function and its prototype deleted.
128 * dispextern.h (produce_stretch_glyph, tty_append_glyph): Add
131 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
133 * image.c (parse_image_spec): Check for nonnegative, not for positive,
134 when checking :margin (Bug#9390).
135 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
136 Renamed from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
137 so that the name doesn't mislead. All uses changed.
139 2011-08-28 Johan Bockgård <bojohan@gnu.org>
141 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
144 2011-08-27 Eli Zaretskii <eliz@gnu.org>
146 * xdisp.c (move_it_to): Don't bail out early when reaching
147 position beyond to_charpos, if we are scanning backwards.
148 (move_it_vertically_backward): When DY == 0, make sure we get to
149 the first character in the line after the newline.
151 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
153 * ccl.c: Improve and simplify overflow checking (Bug#9196).
154 (ccl_driver): Do not generate an out-of-range pointer.
155 (Fccl_execute_on_string): Remove unnecessary check for
156 integer overflow, noted by Stefan Monnier in
157 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
158 Remove a FIXME that didn't need fixing.
159 Simplify the newly-introduced buffer reallocation code.
161 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
163 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
165 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
167 Integer and memory overflow issues (Bug#9196).
169 * doc.c (get_doc_string): Rework so that
170 get_doc_string_buffer_size is the actual buffer size, rather than
171 being 1 less than the actual buffer size; this makes xpalloc more
174 * image.c (x_allocate_bitmap_record, cache_image):
175 * xselect.c (Fx_register_dnd_atom):
176 Simplify previous changes by using xpalloc.
178 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
179 since either will do and ptrdiff_t is convenient with xpalloc.
181 * charset.c (charset_table_size)
182 (struct charset_sort_data.priority): Now ptrdiff_t.
183 (charset_compare): Don't overflow if priorities differ greatly.
184 (Fsort_charsets): Don't assume list length fits in int.
185 Check for size-calculation overflow when allocating sort data.
186 (syms_of_charset): Allocate an initial charset table that is
187 just under 64 KiB, to avoid problems with glibc malloc and mmap.
189 * cmds.c (internal_self_insert): Check for size-calculation overflow.
191 * composite.h (struct composition.glyph_len): Now int, not unsigned.
192 The actual value is always <= INT_MAX, and leaving it unsigned made
193 overflow checking harder.
195 * dispextern.h (struct glyph_matrix.rows_allocated)
196 (struct face_cache.size): Now ptrdiff_t, for convenience in use
197 with xpalloc. The values are still always <= INT_MAX.

201 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
202 (SAFE_NALLOCA): New macro.
204 * region-cache.c (struct boundary.pos, find_cache_boundary)
205 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
206 (set_cache_region, invalidate_region_cache)
207 (revalidate_region_cache, know_region_cache, region_cache_forward)
208 (region_cache_backward, pp_cache):
209 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
210 so that ptrdiff_t * can be passed to xpalloc.
211 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
212 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
213 (pp_cache): Don't assume cache_len fits in int.
214 * region-cache.h: Adjust extern decls to match.
216 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
217 EMACS_INT, since either will do, for xpalloc.

220 (xnmalloc, xnrealloc, xpalloc): New functions.
222 * bidi.c (bidi_shelve_header_size): New constant.
223 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
224 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
226 * bidi.c (bidi_cache_shrink):
227 * buffer.c (overlays_at, overlays_in, record_overlay_string)
229 Don't update size of array until after memory allocation succeeds,
230 because xmalloc/xrealloc may not return.
231 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
232 now that we have proper integer overflow checking.
233 (record_overlay_string, overlay_strings): Catch overflows when
234 calculating size of overlay_str_buf.
236 * callproc.c (Fcall_process): Check for size overflow when
237 calculating size of args2.
238 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
239 Normally we prefer signed values, but sticking with ptrdiff_t would
240 require adding more-complicated checks.
242 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
243 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
244 Redo buffer-overflow calculations to avoid integer overflow.
245 Add a FIXME comment where memory seems to be over-allocated.
247 * character.c (Fstring): Check for size-calculation overflow.
249 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
250 unnecessary integer overflow. Check for size overflow.

263 (row_table_size): Now ptrdiff_t, not int.
264 (scrolling_window): Avoid overflow in size calculations.
265 Don't update size until allocation succeeds.
266 * fns.c (concat): Check for overflow in size calculations.
267 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
268 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
269 (NEXT_ALMOST_PRIME_LIMIT): New constant.
271 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
272 (get_doc_string): Check for size calculation overflow.
273 Don't update size until allocation succeeds.
274 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
275 EMACS_INT, where ptrdiff_t will do.
276 (Fsubstitute_command_keys): Check for string overflow.
278 * editfns.c (set_time_zone_rule): Don't assume environment length
280 (message_length): Now ptrdiff_t, not int.
281 (Fmessage_box): Don't update size until allocation succeeds.
282 Don't assume message length fits in int.
283 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
285 * emacs.c (main): Do not reallocate argv, since there is a null at
286 the end that can be overwritten, and this way there's no need to
287 worry about size-calculation overflow.
288 (sort_args): Check for size-calculation overflow.
290 * eval.c (init_eval_once, grow_specpdl): Don't update size until
292 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.

295 (x_set_scroll_bar_width, x_figure_window_size):
296 Check for integer overflow.
297 (x_set_alpha): Do not assume XINT fits in int.
299 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
300 This is for the members text_lines, text_cols, total_lines, total_cols,
301 where the system imposes an 'int' limit.
303 * fringe.c (Fdefine_fringe_bitmap):
304 Don't update size until alloc works.
306 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
307 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
309 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
310 Check for size-calculation overflow.
311 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
312 do, as we prefer signed integers.
313 (id_to_widget.max_size, id_to_widget.used)
314 (xg_store_widget_in_map, xg_remove_widget_from_map)
315 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
316 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
317 Use and return ptrdiff_t, not int.
318 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
319 * gtkutil.h: Change prototypes to match the above.
321 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
322 are duplicate now that they've been promoted to lisp.h.
323 (x_allocate_bitmap_record, x_alloc_image_color)
324 (make_image_cache, cache_image, xpm_load):
325 Don't update size until alloc is done.
326 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
328 Check for size calculation overflow.
329 (ct_colors_allocated_max): New constant.

338 calculations. Don't update size until allocation succeeds. Redo
339 calculations to avoid overflow.

360 * region-cache.c (move_cache_gap): Check for size calculation overflow.
362 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
363 overflow. Don't bother calling xmalloc when xrealloc will do.
365 * search.c (Freplace_match): Check for size calculation overflow.
366 (Fset_match_data): Don't assume list lengths fit in 'int'.
368 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
369 for command line length. Do not attempt to address one before the
370 beginning of an array, as that's not portable.

373 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
375 (encode_terminal_code, calculate_costs): Check for size
376 calculation overflow.
377 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph

400 Check for size calculation overflow.
401 (cache_face): Treat size calculation overflows as if they were
402 memory exhaustion (the usual treatment), rather than aborting.
404 * xfns.c (x_encode_text, x_set_name_internal)
405 (Fx_change_window_property): Use ptrdiff_t, not int, to count
406 sizes, since they can exceed INT_MAX in size. Check for size
407 calculation overflow.
409 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
410 (xg_select): Check for size calculation overflow.
411 Don't update size until alloc done.
413 * xrdb.c (get_environ_db): Don't assume path length fits in int,
414 as sprintf is limited to int lengths.
416 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
417 (X_LONG_MIN): New macros.
418 Use them to make the following changes clearer.
419 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
420 This change doesn't affect the value now, but it may help remind
421 future maintainers not to raise the value too much later.
422 (SELECTION_QUANTUM): Remove, replacing with ...
423 (selection_quantum): ... new function, which avoids overflow.
425 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
426 assumption that selection length fits in 'int'.
427 (x_reply_selection_request, x_handle_selection_request)
428 (x_get_window_property, receive_incremental_selection)
429 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)

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

439 (lisp_data_to_selection_data, x_property_data_to_lisp):
440 Check for size-calculation overflow.
441 (x_get_window_property, receive_incremental_selection)
442 (lisp_data_to_selection_data, Fx_register_dnd_atom):
443 Don't store size until memory allocation succeeds.
444 (x_get_window_property): Plug memory leak on memory exhaustion.
445 Don't double-block input; malloc is safe here. Don't assume 2**34
446 - 4 fits in unsigned long. Add an xassert to check
447 XGetWindowProperty overflow. Be more careful about overflow
448 calculations, and distinguish size from memory overflow better.
449 (receive_incremental_selection): When tracing, don't assume
450 unsigned int is less than INT_MAX.
451 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
452 harmful) conversions of unsigned short to int.
453 (lisp_data_to_selection_data): Don't assume that integers
454 in the range -65535 through -1 fit in an X unsigned short.
455 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
456 result parameters unless successful. Rely on cons_to_unsigned
457 to report problems with elements; the old code wasn't right anyway.
458 (x_check_property_data): Check for int overflow; we cannot use
459 a wider type due to X limits.
460 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

491 * image.c (xpm_get_color_table_h):
492 * lisp.h (hash_lookup, hash_put):
493 * minibuf.c (Ftest_completion):
494 Use ptrdiff_t for hash table indexes, not int (which is too
495 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
496 32-bit --with-wide-int hosts).
498 * charset.c (Fdefine_charset_internal): Check for integer overflow.
499 Add a FIXME comment about memory leaks.
500 (syms_of_charset): Don't assume xmalloc returns.
502 Don't assume that stated character widths fit in int.
503 * character.c (Fchar_width, c_string_width, lisp_string_width):
504 * character.h (CHAR_WIDTH):
505 * indent.c (MULTIBYTE_BYTES_WIDTH):
506 Use sanitize_char_width to avoid undefined and/or bad behavior
507 with outlandish widths.
508 * character.h (sanitize_tab_width): Renamed from sanitize_width,
509 now that we have two such functions. All uses changed.
510 (sanitize_char_width): New inline function.

518 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
520 * fileio.c: Integer overflow issues with file modes.
521 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
523 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

525 (read_hex, load_charset_map_from_file): Check for integer overflow.
527 * xterm.c: don't go over XClientMessageEvent limit
528 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
529 (x_send_scroll_bar_event): Likewise. Check that the size does not
530 exceed limits imposed by XClientMessageEvent, as well as the usual
531 ptrdiff_t and size_t limits.
533 * keyboard.c: Overflow, signedness and related fixes.
534 (make_lispy_movement): Use same integer type in forward decl
535 that is used in the definition.
536 (read_key_sequence, keyremap_step):
537 Change bufsize argument back to int, undoing my 2011-03-30 change.
538 We prefer signed types, and int is wide enough here.
539 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
540 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
541 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
542 length, not size_t. Use ptrdiff_t for index, not int.
543 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
544 possibility of integer overflow.
546 Overflow, signedness and related fixes for images.

559 on typical 64-bit hosts.
561 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
562 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

567 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
568 (lookup_image): Remove unnecessary tests.
569 (xbm_image_p): Locals are now of int, not EMACS_INT,
570 since parse_image_check makes sure they fit into int.
571 (png_load, gif_load, svg_load_image):
572 Prefer int to unsigned where either will do.
573 (tiff_handler): New function, combining the cores of the
574 old tiff_error_handler and tiff_warning_handler. This
575 function is rewritten to use vsnprintf and thereby avoid
576 stack buffer overflows. It uses only the features of vsnprintf
577 that are common to both POSIX and native Microsoft.
578 (tiff_error_handler, tiff_warning_handler): Use it.
579 (tiff_load, gif_load, imagemagick_load_image):
580 Don't assume :index value fits in 'int'.
581 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
582 (imagemagick_load_image): Check that crop parameters fit into
583 the integer types that MagickCropImage accepts. Don't assume
584 Vimagemagick_render_type has a nonnegative value. Don't assume
585 size_t fits in 'long'.
586 (gs_load): Use printmax_t to print the widest integers possible.
587 Check for integer overflow when computing image height and width.
589 2011-08-26 Eli Zaretskii <eliz@gnu.org>
591 * xdisp.c (redisplay_window): Don't force window start if point

598 (handle_display_spec): Return the value returned by
599 handle_single_display_spec, not just 1 or zero.
600 (handle_single_display_spec): If the display spec is of the form
601 `(space ...)', and specifies display in the text area, return 2
603 (try_cursor_movement): Check for the need to scroll more
604 accurately, and prefer exact match for point under bidi. Don't
605 advance `row' beyond the last row of the window.
607 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
608 into disp_prop; all users changed.
610 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
611 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
612 for the text covered by the display property.
614 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
616 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

622 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
623 buffers, return left-to-right.
624 (set_cursor_from_row): Consider candidate row a win if its glyph
625 represents a newline and point is on that newline. Fixes cursor
626 positioning on the newline at EOL of R2L text within L2R
627 paragraph, and vice versa.
628 (try_cursor_movement): Check continued rows, in addition to
629 continuation rows. Fixes unwarranted scroll when point enters a
630 continued line of R2L text within an L2R paragraph, or vice versa.
631 (cursor_row_p): Consider the case of point being equal to
632 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
633 from the end of a short line to the beginning of a continued line
634 of R2L text within L2R paragraph.
635 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
638 * bidi.c (bidi_check_type): Use xassert.

651 2011-08-22 Kenichi Handa <handa@m17n.org>
653 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
654 extra slot even if the purpose is char-code-property-table.
656 2011-08-23 Eli Zaretskii <eliz@gnu.org>
658 * xdisp.c (redisplay_window): When computing centering_position,
659 account for the height of the header line. (Bug#8874)
661 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
662 instead of CHAR_TO_BYTE. Fixes a crash when a completion
663 candidate is selected by the mouse, and that candidate has a
664 composed character under the mouse.
666 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
667 coordinates reported by pos-visible-in-window-p for a composed
668 character in column zero.
670 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

674 2011-08-22 Eli Zaretskii <eliz@gnu.org>
676 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
677 consider it a hit if to_charpos is anywhere in the range of the
678 composed buffer positions.
680 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
682 * image.c (gif_load): Don't assume that each subimage has the same
683 dimensions as the base image. Handle disposal method that is
684 "undefined" by the gif spec (Bug#9335).
686 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
688 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

691 2011-08-19 Eli Zaretskii <eliz@gnu.org>
693 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
694 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
695 from an Org mode buffer to a Speedbar frame.
697 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
698 a composition, take its buffer position from IT->cmp_it.charpos.
699 Fixes cursor positioning at the beginning of a line that begins
700 with a composed character.
702 2011-08-18 Eli Zaretskii <eliz@gnu.org>
704 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
705 character bidirectional type, use STRONG_L instead. Fixes crashes
706 in a buffer produced by `describe-categories'.
708 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
709 members before the level stack, so they would be saved and
710 restored when copying iterator state. Fixes incorrect reordering
711 around TABs covered by display properties.
713 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
715 * process.c (Fnetwork_interface_list): Correctly determine buffer

778 biditype.h and bidimirror.h.
780 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
781 coordinates of the iterator when restoring from ppos_it.
784 2011-08-14 Kenichi Handa <handa@m17n.org>

801 * nsfns.m (as_script, as_result, as_status): New static variables.
802 (ns_run_ascript): New function.
803 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
804 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
805 the event loop. Get status from as_status (Bug#7276).
807 * nsterm.m (sendEvent): If event is NSApplicationDefined and
808 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
809 the event loop (Bug#7276).

835 (Fnetwork_interface_list): Allocate in increments of bytes instead
836 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
837 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
839 (struct ifflag_def): notrailers is smart on OSX.
840 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
841 Get hardware address with getifaddrs if available.
843 2011-08-12 Eli Zaretskii <eliz@gnu.org>
845 * xdisp.c (iterate_out_of_display_property): xassert that
846 IT->position is set to within IT->object's boundaries. Break from
847 the loop as soon as EOB is reached; avoids infloops in redisplay
848 when IT->position is set up wrongly due to some bug.
849 Set IT->current to match the bidi iterator unconditionally.
850 (push_display_prop): Allow GET_FROM_STRING as IT->method on
851 entry. Force push_it to save on the stack the current
852 buffer/string position, to be restored by pop_it. Fix flags in
853 the iterator structure wrt the object coming from a display
854 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
855 properties. (Bug#9284)
857 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
859 * fontset.c (fontset_get_font_group): Add proper type checks.

869 2011-08-08 Eli Zaretskii <eliz@gnu.org>
871 * xdisp.c (forward_to_next_line_start): Allow to use the
872 no-display-properties-and-no-overlays under bidi display.
873 Set disp_pos in the bidi iterator to avoid searches for display
874 properties and overlays.
876 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
878 * editfns.c (Fset_time_zone_rule): Document relationship with the
881 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to

884 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
886 * composite.c (autocmp_chars): Don't reset point. That is done by
887 restore_point_unwind (Bug#5984).
889 2011-08-07 Juri Linkov <juri@jurta.org>
891 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
892 to show the arg `TIME' instead of `TIMEVAL'.
894 2011-08-06 Eli Zaretskii <eliz@gnu.org>
896 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
897 display property strides EOL and includes a newline, as in
898 longlines-mode. (Bug#9254)
899 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
900 word-wrap under bidirectional display. (Bug#9224)
902 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
903 is non-zero, even if the data buffer is NULL. Fixes a crash in
904 vertical-motion with longlines-mode. (Bug#9254)
906 2011-08-05 Eli Zaretskii <eliz@gnu.org>
908 * bidi.c <bidi_cache_total_alloc>: Now static.
909 (bidi_initialize): Initialize bidi_cache_total_alloc.
911 * xdisp.c (display_line): Release buffer allocated for shelved bidi
914 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
915 amount allocated this far in `bidi_cache_total_alloc'.
916 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
917 non-zero, only free the data buffer without restoring the cache
918 contents. All callers changed.
920 * dispextern.h (bidi_unshelve_cache): Update prototype.
922 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
923 (move_it_in_display_line, move_it_to)
924 (move_it_vertically_backward, move_it_by_lines): Replace the call
925 to xfree to an equivalent call to bidi_unshelve_cache.
926 (move_it_in_display_line_to): Fix logic of returning
927 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
929 2011-08-05 Eli Zaretskii <eliz@gnu.org>
931 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
932 came from a string character with a `cursor' property. (Bug#9229)
934 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
936 * Makefile.in (LIB_PTHREAD): New variable.
937 (LIBES): Add LIB_PTHREAD (Bug#9216).
939 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:

957 the local vars buffer, coding_systems, current_dir.
959 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
961 * keymap.c (Fmake_composed_keymap): Move to subr.el.

968 * xdisp.c (compute_display_string_pos): Remove unused local.
970 2011-08-02 Eli Zaretskii <eliz@gnu.org>
972 Fix slow cursor motion and scrolling in large buffers with
973 selective display, like Org Mode buffers. (Bug#9218)
975 * dispextern.h (struct bidi_it): New member disp_prop_p.
977 * xdisp.c: Remove one-slot cache of display string positions.
978 (compute_display_string_pos): Accept an additional argument
979 DISP_PROP_P; callers changed. Scan at most 5K characters forward
980 for a display string or property. If found, set DISP_PROP_P
983 * bidi.c (bidi_fetch_char): Accept an additional argument
984 DISP_PROP_P, and pass it to compute_display_string_pos.
985 Only handle text covered by a display string if DISP_PROP_P is returned
986 non-zero. All callers of bidi_fetch_char changed.

990 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
992 2010-12-03 Don March <don@ohspite.net>
994 * keymap.c (Fdefine_key): Fix non-prefix key error message when
995 last character M-[char] is translated to ESC [char] (bug#7541).
997 2011-08-02 Kenichi Handa <handa@m17n.org>
999 * lisp.h (uniprop_table): Extern it.
1001 * chartab.c (uniprop_table): Make it non-static.
1003 2011-08-01 Eli Zaretskii <eliz@gnu.org>
1005 * xdisp.c (forward_to_next_line_start): Accept additional argument
1006 BIDI_IT_PREV, and store into it the state of the bidi iterator had
1008 (reseat_at_next_visible_line_start): Use the bidi iterator state
1009 returned by forward_to_next_line_start to restore the state of
1010 it->bidi_it after backing up to previous newline. (Bug#9212)
1012 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
1014 * regex.c (re_comp): Protoize.
1015 (re_exec): Fix return type.
1016 (regexec): Fix type of `ret'. (Bug#9203)
1018 2011-07-29 Paul Eggert <eggert@cs.ucla.edu>
1020 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
1021 This is needed if max-image-size is a floating-point number.
1023 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
1025 * print.c (print_object): Print empty symbol as ##.
1027 * lread.c (read1): Read ## as empty symbol.
1029 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
1031 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
1032 setting frame foreground color (Bug#9175).
1033 (x_set_background_color): Likewise.
1035 * nsmenu.m (-setText): Size tooltip dimensions precisely to
1036 contents (Bug#9176).
1037 (EmacsTooltip -init): Remove bezels and add shadows to
1040 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
1041 or scroll bar (Bug#8470).
1043 * nsfont.m (nsfont_open): Remove assignment to voffset and
1044 unnecessary vars hshink, expand, hd, full_height, min_height.
1045 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
1047 * nsterm.h (nsfont_info): Remove voffset field.
1049 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
1051 Implement strike-through and overline on NextStep (Bug#8863).
1053 * nsfont.m (nsfont_open): Use underline position provided by font,
1054 instead of hard-coded value of 2.
1055 (nsfont_draw): Call ns_draw_text_decoration instead.
1057 * nsterm.h: Add declaration for ns_draw_text_decoration.
1059 * nsterm.m (ns_draw_text_decoration): New function for drawing
1060 underline, overline, and strike-through.
1061 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
1062 ns_draw_text_decoration. Change treatment of cursor drawing to
1063 accomodate underlining, etc.
1065 2011-07-28 Eli Zaretskii <eliz@gnu.org>
1067 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
1070 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
1072 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
1073 Without this fix, if a signal arrives just after memory fills up,
1074 'malloc' might be invoked reentrantly.
1076 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
1077 In other words, assume that every image size is allowed, on non-X
1078 hosts. This assumption is probably wrong, but it lets Emacs compile.
1080 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
1082 * regex.c (re_iswctype): Convert return values to boolean.
1084 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
1086 * xdisp.c (compute_display_string_pos): Don't use cached display
1087 string position if the buffer had its restriction changed.
1090 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
1092 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
1094 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
1096 Integer signedness and overflow and related fixes. (Bug#9079)
1098 * bidi.c: Integer size and overflow fixes.
1099 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
1100 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
1101 (bidi_cache_find_level_change, bidi_cache_ensure_space)
1102 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
1103 (bidi_find_other_level_edge):
1104 Use ptrdiff_t instead of EMACS_INT where either will do.
1105 This works better on 32-bit hosts configured --with-wide-int.
1106 (bidi_cache_ensure_space): Check for size-calculation overflow.
1107 Use % rather than repeated addition, for better worst-case speed.
1108 Don't set bidi_cache_size until after xrealloc returns, because it
1110 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
1111 (bidi_cache_ensure_space): Also check that the bidi cache size
1112 does not exceed that of the largest Lisp string or buffer. See Eli
1113 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
1115 * alloc.c (__malloc_size_t): Remove.
1116 All uses replaced by size_t. See Andreas Schwab's note
1117 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
1119 * image.c: Improve checking for integer overflow.
1120 (check_image_size): Assume that f is nonnull, since
1121 it is always nonnull in practice. This is one less thing to
1122 worry about when checking for integer overflow later.
1123 (x_check_image_size): New function, which checks for integer
1124 overflow issues inside X.
1125 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
1126 This removes the need for a memory_full check.
1127 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
1128 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
1129 (xbm_read_bitmap_data): Change locals back to 'int', since
1130 their values must fit in 'int'.
1131 (xpm_load_image, png_load, tiff_load):
1132 Invoke x_create_x_image_and_pixmap earlier,
1133 to avoid much needless work if the image is too large.
1134 (tiff_load): Treat overly large images as if
1135 x_create_x_image_and_pixmap failed, not as malloc failures.
1136 (gs_load): Use x_check_image_size.
1138 * gtkutil.c: Omit integer casts.
1139 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
1140 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
1142 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
1144 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
1145 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
1146 would wrongly return t on a 64-bit host.
1148 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
1149 The plain *_OVERFLOW macros run afoul of GCC bug 49705
1150 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
1151 and therefore cause GCC to emit a bogus diagnostic in some cases.
1153 * image.c: Integer signedness and overflow and related fixes.
1154 This is not an exhaustive set of fixes, but it's time to
1155 record what I've got.
1156 (lookup_pixel_color, check_image_size): Remove redundant decls.
1157 (check_image_size): Don't assume that arbitrary EMACS_INT values
1158 fit in 'int', or that arbitrary 'double' values fit in 'int'.
1159 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
1160 (tiff_load, imagemagick_load_image):
1161 Check for overflow in size calculations.
1162 (x_create_x_image_and_pixmap): Remove unnecessary test for
1163 xmalloc returning NULL; that can't happen.
1164 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
1165 (xpm_color_bucket): Use better integer hashing function.
1166 (xpm_cache_color): Don't possibly over-allocate memory.
1167 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
1168 (gif_memory_source):
1169 Use ptrdiff_t, not int or size_t, to record sizes.
1170 (png_load): Don't assume values greater than 2**31 fit in 'int'.
1171 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
1172 either works, as we prefer signed integers.
1173 (tiff_read_from_memory, tiff_write_from_memory):
1174 Return tsize_t, not size_t, since that's what the TIFF API wants.
1175 (tiff_read_from_memory): Don't fail simply because the read would
1176 go past EOF; instead, return a short read.
1177 (tiff_load): Omit no-longer-needed casts.
1178 (Fimagemagick_types): Don't assume size fits into 'int'.
1180 Improve hashing quality when configured --with-wide-int.
1181 * fns.c (hash_string): New function, taken from sxhash_string.
1182 Do not discard information about ASCII character case; this
1183 discarding is no longer needed.
1184 (sxhash-string): Use it. Change sig to match it. Caller changed.
1185 * lisp.h: Declare it.
1186 * lread.c (hash_string): Remove, since we now use fns.c's version.
1187 The fns.c version returns a wider integer if --with-wide-int is
1188 specified, so this should help the quality of the hashing a bit.
1190 * emacs.c: Integer overflow minor fix.
1191 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
1192 Define only if GNU_LINUX.
1193 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
1195 * dispnew.c: Integer signedness and overflow fixes.
1196 Remove unnecessary forward decls, that were a maintenance hassle.
1197 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
1199 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
1200 (scrolling_window): Use ptrdiff_t, not int, for byte count.
1201 (prepare_desired_row, line_draw_cost):
1202 Use int, not unsigned, where either works.
1203 (save_current_matrix, restore_current_matrix):
1204 Use ptrdiff_t, not size_t, where either works.
1205 (init_display): Check for overflow more accurately, and without
1206 relying on undefined behavior.
1208 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
1209 Remove, replacing with the new symbols in lisp.h. All uses changed.
1210 * fileio.c (make_temp_name):
1211 * filelock.c (lock_file_1, lock_file):
1212 * xdisp.c (message_dolog):
1213 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
1214 Use pMd etc. instead.
1215 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
1216 replacing the pWIDE etc. symbols removed from editfns.c.
1218 * keyboard.h (num_input_events): Now uintmax_t.
1219 This is (very slightly) less likely to mess up due to wraparound.
1222 * buffer.c: Integer signedness fixes.
1223 (alloc_buffer_text, enlarge_buffer_text):
1224 Use ptrdiff_t rather than size_t when either will do, as we prefer
1227 * alloc.c: Integer signedness and overflow fixes.
1228 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
1229 (__malloc_size_t): Default to size_t, not to int.
1230 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
1231 (Fgarbage_collect, mark_object_loop_halt, mark_object):
1232 Prefer ptrdiff_t to size_t when either would do, as we prefer
1234 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
1235 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
1236 Now const. Initialize with values that are in range even if char
1238 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
1239 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
1240 These functions do the right thing with sizes > 2**32.
1241 (check_depth): Now ptrdiff_t, not int.
1242 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
1243 Adjust to new way of storing sizes. Check for size overflow bugs
1245 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
1246 slightly wrong anyway, as it missed one instance of
1247 XMALLOC_OVERRUN_CHECK_OVERHEAD.
1248 (refill_memory_reserve): Omit needless cast to size_t.
1249 (mark_object_loop_halt): Mark as externally visible.
1251 * xselect.c: Integer signedness and overflow fixes.
1252 (Fx_register_dnd_atom, x_handle_dnd_message):
1253 Use ptrdiff_t, not size_t, since we prefer signed.
1254 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
1255 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
1256 x_dnd_atoms_size and x_dnd_atoms_length.
1258 * doprnt.c: Prefer signed to unsigned when either works.
1260 * doprnt.c (doprnt):
1262 * xdisp.c (vmessage):
1263 Use ptrdiff_t, not size_t, when using or implementing doprnt,
1264 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
1265 prefer signed arithmetic to avoid comparison confusion.
1266 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
1267 but is a bit tricky.
1269 Assume freestanding C89 headers, string.h, stdlib.h.
1270 * data.c, doprnt.c, floatfns.c, print.c:
1271 Include float.h unconditionally.
1272 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
1273 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
1274 * regex.c: Likewise for stddef.h, string.h.
1275 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
1276 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
1277 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
1278 (STDC_HEADERS): Remove obsolete defines.
1279 * sysdep.c: Include limits.h unconditionally.
1281 Assume support for memcmp, memcpy, memmove, memset.
1282 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
1283 * regex.c (memcmp, memcpy):
1284 Remove; we assume C89 now.
1286 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
1287 (__malloc_safe_bcopy): Remove; no longer needed.
1289 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
1290 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
1291 well either way, and we prefer signed to unsigned.
1293 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
1295 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
1296 closes the connection while we're reading (bug#9182).
1298 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
1300 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
1301 are specified (Bug#9168).
1303 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
1305 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
1306 Found by GCC static checking and --with-wide-int on a 32-bit host.
1308 2011-07-25 Eli Zaretskii <eliz@gnu.org>
1310 * xdisp.c (compute_display_string_pos): Fix logic of caching
1311 previous display string position. Initialize cached_prev_pos to
1312 -1. Fixes slow-down at the beginning of a buffer.
1314 2011-07-24 Eli Zaretskii <eliz@gnu.org>
1316 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
1317 for attrs[LFACE_FONTSET_INDEX].
1319 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
1321 * xml.c (parse_region): Remove unused local
1322 that was recently introduced.
1324 2011-07-23 Eli Zaretskii <eliz@gnu.org>
1326 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
1327 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
1329 * xdisp.c (move_it_in_display_line_to): Record the best matching
1330 position for TO_CHARPOS while scanning the line, and restore it on
1331 exit if none of the characters scanned was an exact match.
1332 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
1333 when exact match is impossible due to invisible text, and the
1334 lines are truncated.
1336 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
1338 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
1341 2011-07-22 Eli Zaretskii <eliz@gnu.org>
1343 Fix a significant slow-down of cursor motion with C-n, C-p,
1344 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
1345 auto-repeat under bidi redisplay in fontified buffers.
1346 * xdisp.c (compute_stop_pos_backwards): New function.
1347 (next_element_from_buffer): Call compute_stop_pos_backwards to
1348 find a suitable prev_stop when we find ourselves before
1350 (reseat): Don't look for prev_stop, as that could mean a very long
1352 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
1353 <cached_disp_overlay_modiff>: Cache for last found display string
1355 (compute_display_string_pos): Return the cached position if asked
1356 about the same buffer in the same area of character positions, and
1357 the buffer wasn't changed since the time the display string
1358 position was cached.
1360 2011-07-22 Eli Zaretskii <eliz@gnu.org>
1362 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
1363 is an integer, which is important for empty lines. (Bug#9149)
1365 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
1367 * frame.c (Fmodify_frame_parameters): In tty case, update the
1368 default face if necessary (Bug#4238).
1370 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
1372 * editfns.c (Fstring_to_char): No need to explain what a character
1373 is in the docstring (Bug#6576).
1375 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
1377 * xml.c (parse_region): Make sure we always return a tree.
1379 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
1381 * xml.c (parse_region): If a document contains only comments,
1384 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
1386 * xml.c (make_dom): Return comments, too.
1388 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
1391 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
1392 and the surrounding thread.
1393 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
1394 rather than fgets, and retry after EINTR. Otherwise, 'emacs
1395 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
1397 * s/openbsd.h (BROKEN_SIGIO): Define.
1398 * unexelf.c (unexec) [__OpenBSD__]:
1399 Don't update the .mdebug section of the Alpha COFF symbol table.
1401 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
1403 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
1406 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
1408 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
1409 This fixes some race conditions on the permissions of any newly
1412 * alloc.c (valid_pointer_p): Use pipe, not open.
1413 This fixes some permissions issues when debugging.
1415 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
1416 If fchown fails to set both uid and gid, try to set just gid,
1417 as that is sometimes allowed. Adjust the file's mode to eliminate
1418 setuid or setgid bits that are inappropriate if fchown fails.
1420 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
1422 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
1423 to compare Lisp_Objects.
1424 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
1425 global_gnutls_log_level, don't mistake it for a Lisp_Object.
1426 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
1428 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
1430 * lread.c (read_integer): Unread even EOF character.
1431 (read1): Likewise. Properly record start position of symbol.
1433 * lread.c (read1): Read `#:' as empty uninterned symbol if no
1434 symbol character follows.
1436 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
1438 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
1439 This works around a problem with the previous change to Fcopy_file.
1440 Recent glibc declares fchown with __attribute__((warn_unused_result)),
1441 and without this change, GCC might complain about discarding
1442 fchown's return value.
1444 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
1446 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
1448 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
1450 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
1452 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>

2057 Random fixes. E.g., (random) never returned negative values.
2058 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
2059 subseconds part to the entropy, as that's a bit more random.
2060 Prefer signed to unsigned, since the signedness doesn't matter and
2061 in general we prefer signed. When given a limit, use a
2062 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
2063 latter isn't right if USE_2_TAGS_FOR_INTS.
2064 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
2065 not 0..VALMASK. Don't discard "excess" bits that random () returns.

2078 This is more efficient than Ffile_directory_p and avoids a minor race.
2080 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
2082 * buffer.c (Foverlay_put): Say what the return value is
2085 * fileio.c (barf_or_query_if_file_exists): Check first if the file

2088 (barf_or_query_if_file_exists): Make the "File is a directory"
2089 error be more correct.
2091 * fns.c (Frequire): Remove the mention of the .gz files, since
2092 that's installation-specific, but keep the mention of
2093 `get-load-suffixes'.
2095 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
2097 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

2108 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

2210 * eval.c (struct backtrace): Simplify and port the data structure.
2211 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
2212 signed bit field, as this assumption is not portable and it makes
2213 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
2214 "char debug_on_exit : 1" as this is not portable either; instead,
2215 use the portable "unsigned int debug_on_exit : 1". Remove unused
2216 member evalargs. Remove obsolete comments about cc bombing out.

2373 * xsettings.c (syms_of_xsettings):
2374 * xterm.c (syms_of_xterm): Use DEFSYM.
2376 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
2378 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
2380 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
2382 Integer and buffer overflow fixes (Bug#8873).
2384 * print.c (printchar, strout): Check for string overflow.
2385 (PRINTPREPARE, printchar, strout):
2386 Don't set size unless allocation succeeds.
2388 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
2389 for sizes. Check for string overflow more accurately.
2390 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
2392 * macros.c: Integer and buffer overflow fixes.
2393 * keyboard.h (struct keyboard.kbd_macro_bufsize):
2394 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
2395 Use ptrdiff_t, not int, for sizes.
2396 Don't increment bufsize until after realloc succeeds.
2397 Check for size-calculation overflow.
2398 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
2400 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
2402 * lread.c: Integer overflow fixes.
2403 (read_integer): Radix is now EMACS_INT, not int,
2404 to improve quality of diagnostics for out-of-range radices.
2405 Calculate buffer size correctly for out-of-range radices.
2406 (read1): Check for integer overflow in radices, and in
2407 read-circle numbers.
2408 (read_escape): Avoid int overflow.
2409 (Fload, openp, read_buffer_size, read1)
2410 (substitute_object_recurse, read_vector, read_list, map_obarray):
2411 Use ptrdiff_t, not int, for sizes.
2412 (read1): Use EMACS_INT, not int, for sizes.
2413 Check for size overflow.
2415 * image.c (cache_image): Check for size arithmetic overflow.
2417 * lread.c: Integer overflow issues.
2418 (saved_doc_string_size, saved_doc_string_length)
2419 (prev_saved_doc_string_size, prev_saved_doc_string_length):
2420 Now ptrdiff_t, not int.
2421 (read1): Don't assume doc string length fits in int. Check for
2422 out-of-range doc string lengths.
2423 (read_list): Don't assume file position fits in int.
2424 (read_escape): Check for hex character overflow.
2426 2011-06-22 Leo Liu <sdl.web@gmail.com>
2428 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
2429 Move to minibuffer.el.
2431 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
2433 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
2434 The following patches are for when GLYPH_DEBUG && !XASSERT.
2435 * dispextern.h (trace_redisplay_p, dump_glyph_string):
2436 * dispnew.c (flush_stdout):
2437 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
2438 Mark as externally visible.
2439 * dispnew.c (check_window_matrix_pointers): Now static.
2440 * dispnew.c (window_to_frame_vpos):
2441 * xfns.c (unwind_create_frame):
2442 * xterm.c (x_check_font): Remove unused local.
2443 * scroll.c (CHECK_BOUNDS):
2444 * xfaces.c (cache_fache): Rename local to avoid shadowing.
2445 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
2446 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
2447 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
2448 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
2450 (debug_method_add): Use va_list and vsprintf rather than relying
2451 on undefined behavior with wrong number of arguments.
2452 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
2453 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
2454 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
2455 since we're not interested in debugging glyphs with old libraries.
2456 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
2457 GCC 4.6.0's static checking.
2459 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
2461 Integer overflow and signedness fixes (Bug#8873).
2462 A few related buffer overrun fixes, too.
2464 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
2466 * dispextern.h (struct face.stipple):
2467 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
2468 (x_bitmap_mask, x_allocate_bitmap_record)
2469 (x_create_bitmap_from_data, x_create_bitmap_from_file)
2470 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
2471 (x_create_bitmap_from_xpm_data):
2472 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
2473 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
2475 * xfaces.c (load_pixmap):
2476 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
2477 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
2478 (.bitmaps_last, struct x_output.icon_bitmap):
2479 Use ptrdiff_t, not int, for bitmap indexes.
2480 (x_allocate_bitmap_record): Check for size overflow.
2481 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
2483 Use ptrdiff_t, not int, for overlay counts.
2484 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
2485 * editfns.c (overlays_around, get_pos_property):
2486 * textprop.c (get_char_property_and_overlay):
2487 * xdisp.c (next_overlay_change, note_mouse_highlight):
2488 * xfaces.c (face_at_buffer_position):
2489 * buffer.c (OVERLAY_COUNT_MAX): New macro.
2490 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
2491 (Fnext_overlay_change, Fprevious_overlay_change)
2492 (mouse_face_overlay_overlaps, Foverlays_in):
2493 Use ptrdiff_t, not int, for sizes.
2494 (overlays_at, overlays_in): Check for size-calculation overflow.
2496 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
2498 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
2499 (x_session_initialize): Do not assume string length fits in int.
2501 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
2502 This is unlikely, but can occur if DPI is outlandish.
2504 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
2505 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
2507 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
2508 * xrdb.c (magic_file_p, search_magic_path):
2509 Omit last arg SUFFIX; it was always 0. All callers changed.
2510 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
2512 * xfont.c (xfont_match): Avoid need for strlen.
2514 * xfns.c: Don't assume strlen fits in int.
2515 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
2517 * xdisp.c (message_log_check_duplicate): Return intmax_t,
2518 not unsigned long, as we prefer signed integers. All callers changed.
2519 Detect integer overflow in repeat count.
2520 (message_dolog): Don't assume print length fits in 39 bytes.
2521 (display_mode_element): Don't assume strlen fits in int.
2523 * termcap.c: Don't assume sizes fit in int and never overflow.
2524 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
2525 (gobble_line): Check for size-calculation overflow.
2527 * minibuf.c (Fread_buffer):
2528 * lread.c (intern, intern_c_string):
2529 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
2530 Don't assume string length fits in int.
2532 * keyboard.c (parse_tool_bar_item):
2533 * gtkutil.c (style_changed_cb): Avoid need for strlen.
2535 * font.c: Don't assume string length fits in int.
2536 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
2537 Use ptrdiff_t, not int.
2538 (font_intern_prop): Don't assume string length fits in int.
2539 Don't assume integer property fits in fixnum.
2540 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
2542 * filelock.c: Fix some buffer overrun and integer overflow issues.
2543 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
2544 Reformulate so as not to need the command string.
2545 Invoke gzip -cd rather than gunzip, as it's more portable.
2546 (lock_info_type, lock_file_1, lock_file):
2547 Don't assume pid_t and time_t fit in unsigned long.
2548 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
2549 (current_lock_owner): Prefer signed type for sizes.
2550 Use memcpy, not strncpy, where memcpy is what is really wanted.
2551 Don't assume (via atoi) that time_t and pid_t fit in int.
2552 Check for time_t and/or pid_t out of range, e.g., via a network share.
2553 Don't alloca where an auto var works fine.
2555 * fileio.c: Fix some integer overflow issues.
2556 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
2557 Don't assume string length fits in int.
2558 (directory_file_name): Don't assume string length fits in long.
2559 (make_temp_name): Don't assume pid fits in int, or that its print
2560 length is less than 20.
2562 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
2564 * coding.c (make_subsidiaries): Don't assume string length fits in int.
2566 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
2568 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
2569 We prefer signed integers, even for size calculations.
2571 * emacs.c: Don't assume string length fits in 'int'.
2572 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
2573 (main): Don't invoke strlen when not needed.
2575 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
2576 (XD_DEBUG_MESSAGE): Don't waste a byte.
2578 * callproc.c (getenv_internal_1, getenv_internal)
2580 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
2582 * lread.c (invalid_syntax): Omit length argument.
2583 All uses changed. This doesn't fix a bug, but it simplifies the
2584 code away from its former Hollerith-constant appearance, and it's
2585 one less 'int' to worry about when looking at integer-overflow issues.
2586 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
2588 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
2589 This didn't break anything, but it didn't help either.
2590 It's confusing to put a bogus integer in a place where the actual
2591 value does not matter.
2592 (LIST_END_P): Remove unused macro and its bogus comment.
2593 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
2595 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
2596 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
2598 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
2599 We prefer signed types, and the value cannot exceed the EMACS_INT
2600 range anyway (because otherwise the length would not be representable).
2601 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
2602 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
2603 This avoids a GCC warning when WIDE_EMACS_INT.
2605 * indent.c (sane_tab_width): New function.
2606 (current_column, scan_for_column, Findent_to, position_indentation)
2607 (compute_motion): Use it. This is just for clarity.
2608 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
2610 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
2612 * lisp.h (lint_assume): New macro.
2613 * composite.c (composition_gstring_put_cache):
2614 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
2616 * editfns.c, insdel.c:
2617 Omit unnecessary forward decls, to simplify future changes.
2619 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
2621 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
2623 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
2624 Use much-faster test for byte-length change.
2625 Don't assume string byte-length fits in 'int'.
2626 Check that character arg fits in 'int'.
2627 (mapcar1): Declare byte as byte, for clarity.
2629 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
2631 * fns.c (concat): Catch string overflow earlier.
2632 Do not rely on integer wraparound.
2634 * dispextern.h (struct it.overlay_strings_charpos)
2635 (struct it.selective): Now EMACS_INT, not int.
2636 * xdisp.c (forward_to_next_line_start)
2637 (back_to_previous_visible_line_start)
2638 (reseat_at_next_visible_line_start, next_element_from_buffer):
2639 Don't arbitrarily truncate the value of 'selective' to int.
2641 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
2643 * composite.c: Don't truncate sizes to 'int'.
2644 (composition_gstring_p, composition_reseat_it)
2645 (composition_adjust_point): Use EMACS_INT, not int.
2646 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
2647 not EMACS_UINT, for indexes.
2649 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
2651 * buffer.c: Include <verify.h>.
2652 (struct sortvec.priority, struct sortstr.priority):
2653 Now EMACS_INT, not int.
2654 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
2655 (struct sortstr.size, record_overlay_string)
2656 (struct sortstrlist.size, struct sortlist.used):
2657 Don't truncate size to int.
2658 (record_overlay_string): Check for size-calculation overflow.
2659 (init_buffer_once): Check at compile-time, not run-time.
2661 2011-06-22 Jim Meyering <meyering@redhat.com>
2663 Don't leak an XBM-image-sized buffer
2664 * image.c (xbm_load): Free the image buffer after using it.
2666 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
2669 * composite.c (find_automatic_composition): Omit needless 'return 0;'
2670 that Sun C diagnosed.
2671 * fns.c (secure_hash): Fix pointer signedness issue.
2672 * intervals.c (static_offset_intervals): New function.
2673 (offset_intervals): Use it.
2675 2011-06-21 Leo Liu <sdl.web@gmail.com>
2678 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
2681 * fns.c (secure_hash): Rename from crypto_hash_function and change
2682 the first arg to accept symbols.
2683 (Fsecure_hash): New primitive.
2684 (syms_of_fns): New symbols.
2686 2011-06-20 Deniz Dogan <deniz@dogan.se>
2688 * process.c (Fset_process_buffer): Clarify return value in
2691 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
2693 * dispnew.c (add_window_display_history): Use BVAR.
2695 * xdisp.c (debug_method_add): Use BVAR.
2696 (check_window_end, dump_glyph_matrix, dump_glyph)
2697 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
2699 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
2702 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
2703 check till after the cache is created in init_frame_faces.
2705 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
2707 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
2709 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
2711 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
2712 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
2713 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
2715 Improve buffer-overflow checking (Bug#8873).
2716 * fileio.c (Finsert_file_contents):
2717 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
2718 Remove the old (too-loose) buffer overflow checks.
2719 They weren't needed, since make_gap checks for buffer overflow.
2720 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
2721 The old code merely checked for Emacs fixnum overflow, and relied
2722 on undefined (wraparound) behavior. The new code avoids undefined
2723 behavior, and also checks for ptrdiff_t and/or size_t overflow.
2725 * editfns.c (Finsert_char): Don't dump core with very negative counts.
2726 Tune. Don't use wider integers than needed. Don't use alloca.
2727 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
2729 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
2731 * insdel.c, lisp.h (buffer_overflow): New function.
2732 (insert_from_buffer_1, replace_range, replace_range_2):
2733 * insdel.c (make_gap_larger):
2734 * editfns.c (Finsert_char):
2735 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
2737 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
2739 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
2741 Integer overflow and signedness fixes (Bug#8873).
2743 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
2744 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
2746 * fileio.c: Don't assume EMACS_INT fits in off_t.
2747 (emacs_lseek): New static function.
2748 (Finsert_file_contents, Fwrite_region): Use it.
2749 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
2751 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
2753 * fns.c: Don't overflow int when computing a list length.
2754 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
2755 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
2756 truncation on 64-bit hosts. Check for QUIT every
2757 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
2758 faster and is responsive enough.
2759 (Flength): Report an error instead of overflowing an integer.
2760 (Fsafe_length): Return a float if the value is not representable
2761 as a fixnum. This shouldn't happen except in contrived situations.
2762 (Fnthcdr, Fsort): Don't assume list length fits in int.
2763 (Fcopy_sequence): Don't assume vector length fits in int.
2765 * alloc.c: Check that resized vectors' lengths fit in fixnums.
2766 (header_size, word_size): New constants.
2767 (allocate_vectorlike): Don't check size overflow here.
2768 (allocate_vector): Check it here instead, since this is the only
2769 caller of allocate_vectorlike that could cause overflow.
2770 Check that the new vector's length is representable as a fixnum.
2772 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
2773 The previous code was bogus. For example, next_almost_prime (32)
2774 returned 39, which is undesirable as it is a multiple of 3; and
2775 next_almost_prime (24) returned 25, which is a multiple of 5 so
2776 why was the code bothering to check for multiples of 7?
2778 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
2780 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
2782 Variadic C functions now count arguments with ptrdiff_t.
2783 This partly undoes my 2011-03-30 change, which replaced int with size_t.
2784 Back then I didn't know that the Emacs coding style prefers signed int.
2785 Also, in the meantime I found a few more instances where arguments
2786 were being counted with int, which may truncate counts on 64-bit
2787 machines, or EMACS_INT, which may be unnecessarily wide.
2788 * lisp.h (struct Lisp_Subr.function.aMANY)
2789 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
2790 Arg counts are now ptrdiff_t, not size_t.
2791 All variadic functions and their callers changed accordingly.
2792 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
2793 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
2794 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
2795 * callint.c (Fcall_interactively): Check arg count for overflow,
2796 to avoid potential buffer overrun. Use signed char, not 'int',
2797 for 'varies' array, so that we needn't bother to check its size
2798 calculation for overflow.
2799 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
2800 * eval.c (apply_lambda):
2801 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
2802 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
2803 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
2805 * callint.c (Fcall_interactively): Don't use index var as event count.
2807 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
2808 * mem-limits.h (SIZE): Remove; no longer used.
2810 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
2812 Remove unnecessary casts.
2813 * xterm.c (x_term_init):
2814 * xfns.c (x_set_border_pixel):
2815 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
2816 These aren't needed now that we assume ANSI C.
2818 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
2819 It's more likely to cause problems (due to unsigned overflow)
2822 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
2824 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
2826 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
2828 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
2830 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
2832 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
2834 GLYPH_CODE_FACE returns EMACS_INT, not int.
2835 * dispextern.h (merge_faces):
2836 * xfaces.c (merge_faces):
2837 * xdisp.c (get_next_display_element, next_element_from_display_vector):
2838 Don't assume EMACS_INT fits in int.
2840 * character.h (CHAR_VALID_P): Remove unused parameter.
2841 * fontset.c, lisp.h, xdisp.c: All uses changed.
2843 * editfns.c (Ftranslate_region_internal): Omit redundant test.
2845 * fns.c (concat): Minor tuning based on overflow analysis.
2846 This doesn't fix any bugs. Use int to hold character, instead
2847 of constantly refetching from Emacs object. Use XFASTINT, not
2848 XINT, for value known to be a character. Don't bother comparing
2849 a single byte to 0400, as it's always less.
2851 * floatfns.c (Fexpt):
2852 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
2854 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
2857 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
2859 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
2860 Without this fix, on a 64-bit host (aset S 0 4294967386) would
2861 incorrectly succeed when S was a string, because 4294967386 was
2862 truncated before it was used.
2864 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
2865 Otherwise, an out-of-range integer could cause undefined behavior
2868 * composite.c: Use int, not EMACS_INT, for characters.
2869 (fill_gstring_body, composition_compute_stop_pos): Use int, not
2870 EMACS_INT, for values that are known to be in character range.
2871 This doesn't fix any bugs but is the usual style inside Emacs and
2872 may generate better code on 32-bit machines.
2874 Make sure a 64-bit char is never passed to ENCODE_CHAR.
2875 This is for reasons similar to the recent CHAR_STRING fix.
2876 * charset.c (Fencode_char): Check that character arg is actually
2877 a character. Pass an int to ENCODE_CHAR.
2878 * charset.h (ENCODE_CHAR): Verify that the character argument is no
2879 wider than 'int', as a compile-time check to prevent future regressions
2882 * character.c (char_string): Remove unnecessary casts.
2884 Make sure a 64-bit char is never passed to CHAR_STRING.
2885 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
2886 by silently ignoring the top 32 bits, allowing some values
2887 that were far too large to be valid characters.
2888 * character.h: Include <verify.h>.
2889 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
2890 arguments are no wider than unsigned, as a compile-time check
2891 to prevent future regressions in this area.
2893 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
2894 (Fsubst_char_in_region):
2896 * xdisp.c (decode_mode_spec_coding):
2897 Adjust to CHAR_STRING's new requirement.
2898 * editfns.c (Finsert_char, Fsubst_char_in_region):
2899 * fns.c (concat): Check that character args are actually
2900 characters. Without this test, these functions did the wrong
2901 thing with wildly out-of-range values on 64-bit hosts.
2903 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
2904 These casts should not be needed on 32-bit hosts, either.
2905 * keyboard.c (read_char):
2906 * lread.c (Fload): Remove casts to unsigned.
2908 * lisp.h (UNSIGNED_CMP): New macro.
2909 This fixes comparison bugs on 64-bit hosts.
2910 (ASCII_CHAR_P): Use it.
2911 * casefiddle.c (casify_object):
2912 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
2913 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
2914 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
2915 * dispextern.h (FACE_FROM_ID):
2916 * keyboard.c (read_char): Use UNSIGNED_CMP.
2918 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
2919 not to EMACS_INT, to avoid GCC warning.
2921 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
2923 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
2924 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
2925 isn't needed on 32-bit machines.
2927 * buffer.c (Fgenerate_new_buffer_name):
2928 Use EMACS_INT for count, not int.
2929 (advance_to_char_boundary): Return EMACS_INT, not int.
2931 * data.c (Qcompiled_function): Now static.
2933 * window.c (window_body_lines): Now static.
2935 * image.c (gif_load): Rename local to avoid shadowing.
2937 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
2938 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
2939 * alloc.c (make_save_value): Integer argument is now of type
2941 (mark_object): Use ptrdiff_t, not int.
2942 * lisp.h (pD): New macro.
2943 * print.c (print_object): Use it.
2945 * alloc.c: Use EMACS_INT, not int, to count objects.
2946 (total_conses, total_markers, total_symbols, total_vector_size)
2947 (total_free_conses, total_free_markers, total_free_symbols)
2948 (total_free_floats, total_floats, total_free_intervals)
2949 (total_intervals, total_strings, total_free_strings):
2950 Now EMACS_INT, not int. All uses changed.
2951 (Fgarbage_collect): Compute overall total using a double, so that
2952 integer overflow is less likely to be a problem. Check for overflow
2953 when converting back to an integer.
2954 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
2955 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
2956 These were 'int' variables that could overflow on 64-bit hosts;
2957 they were never used, so remove them instead of repairing them.
2958 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
2959 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
2960 Previously, this ceilinged at INT_MAX, but that doesn't work on
2962 (allocate_pseudovector): Don't use EMACS_INT when int would do.
2964 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
2965 (allocate_vectorlike): Check for ptrdiff_t overflow.
2966 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
2967 when a (possibly-narrower) signed value would do just as well.
2968 We prefer using signed arithmetic, to avoid comparison confusion.
2970 * alloc.c: Catch some string size overflows that we were missing.
2971 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
2972 for convenience in STRING_BYTES_MAX.
2973 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
2974 The definition here is exact; the one in lisp.h was approximate.
2975 (allocate_string_data): Check for string overflow. This catches
2976 some instances we weren't catching before. Also, it catches
2977 size_t overflow on (unusual) hosts where SIZE_MAX <= min
2978 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
2979 and ptrdiff_t and EMACS_INT are both 64 bits.
2981 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
2982 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
2983 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
2985 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
2987 * alloc.c (Fmake_string): Check for out-of-range init.
2989 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
2991 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
2993 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
2995 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
2996 xg_get_default_scrollbar_width.
2998 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
2999 (int_gtk_range_get_value): Move to the scroll bar part of the file.
3000 (style_changed_cb): Call update_theme_scrollbar_width and call
3001 x_set_scroll_bar_default_width and xg_frame_set_char_size for
3002 all frames (Bug#8505).
3003 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
3004 Call gtk_window_set_resizable if HAVE_GTK3.
3005 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
3006 and height if HAVE_GTK3 (Bug#8505).
3007 (scroll_bar_width_for_theme): New variable.
3008 (update_theme_scrollbar_width): New function.
3009 (xg_get_default_scrollbar_width): Move code to
3010 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
3011 (xg_initialize): Call update_theme_scrollbar_width.
3013 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
3015 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
3017 2011-06-12 Martin Rudalics <rudalics@gmx.at>

3022 * window.c (temp_output_buffer_show): Call display_buffer with
3023 second argument Vtemp_buffer_show_specifiers and reset latter
3024 immediately after the call.
3025 (Vtemp_buffer_show_specifiers): New variable.

3569 bidi_it->nchars is non-positive.
3570 (bidi_level_of_next_char): Don't try to lookup the cache for the

3589 (compute_display_string_pos): Accept additional argument
3590 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
3591 value of a `display' property is a "replacing spec".
3592 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
3593 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

3623 * gnutls.c: Use Emacs's memory allocators.
3624 Without this change, the gnutls library would invoke malloc etc.
3625 directly, which causes problems on non-SYNC_INPUT hosts, and which
3626 runs afoul of improving memory_full behavior. (Bug#8761)
3627 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
3628 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
3629 xfree instead of the default malloc, realloc, free.
3630 (Fgnutls_boot): No need to check for memory allocation failure,
3631 since xmalloc does that for us.

3657 * ccl.c (ccl_driver):
3658 Check for overflow when converting EMACS_INT to int.
3659 * fns.c, image.c: Remove unnecessary static decls that would otherwise

3662 Check for integer overflow with large hash tables.
3663 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
3664 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
3665 (SXHASH_REDUCE): New macro.
3666 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
3667 Use it instead of discarding useful hash info with large hash values.
3668 (sxhash_float): New function.
3669 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
3670 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
3671 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
3672 Rewrite to use FIXNUM_BITS, as this simplifies things.
3673 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
3674 Adjust signatures to match updated version of code.
3675 (consing_since_gc): Now EMACS_INT, since a single hash table can

3725 Make it possible to run ./temacs.
3727 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
3728 syms_of_callproc does the same thing. Remove test for
3729 "initialized", do it in the caller.
3730 * emacs.c (main): Avoid calling set_initial_environment when dumping.

3741 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3743 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
3744 (CCL_CODE_MIN): New macro.
3746 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
3748 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
3750 * eval.c (Qdebug): Now static.
3751 * lisp.h (Qdebug): Remove decl. This reverts a part of the
3752 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
3753 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
3755 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3757 * image.c: Various fixes to ImageMagick code comments.
3758 (Fimagemagick_types): Doc fix.
3760 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
3762 Minor fixes prompted by GCC 4.6.0 warnings.
3764 * xselect.c (converted_selections, conversion_fail_tag): Now static.
3766 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
3767 (x_clipboard_manager_save_all): Move extern decl to ...
3768 * xterm.h: ... here, so that it can be checked for consistency.
3770 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3772 * xselect.c (x_clipboard_manager_save_frame)
3773 (x_clipboard_manager_save_all): New functions.
3774 (Fx_clipboard_manager_save): Lisp function deleted.
3776 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
3777 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
3779 * xterm.h: Update prototype.
3781 2011-05-28 William Xu <william.xwl@gmail.com>
3783 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
3786 2011-05-28 Jim Meyering <meyering@redhat.com>
3788 Avoid a sign-extension bug in crypto_hash_function.
3789 * fns.c (to_uchar): Define.
3790 (crypto_hash_function): Use it to convert some newly-signed
3791 variables to unsigned, to avoid sign-extension bugs. For example,
3792 without this change, (md5 "truc") would evaluate to
3793 45723a2aff78ff4fff7fff1114760e62 rather than the expected
3794 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
3795 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
3797 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3799 Integer overflow fixes.
3801 * dbusbind.c: Serial number integer overflow fixes.
3802 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
3803 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
3804 to hold a serial number that is too large for a fixnum.
3805 (Fdbus_method_return_internal, Fdbus_method_error_internal):
3806 Check for serial numbers out of range. Decode any serial number
3807 that was so large that it became a float. (Bug#8722)
3809 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
3810 (Fdbus_call_method, Fdbus_call_method_asynchronously):
3811 Use XFASTINT rather than XUINT when numbers are nonnegative.
3812 (xd_append_arg, Fdbus_method_return_internal):
3813 (Fdbus_method_error_internal): Likewise. Also, for unsigned
3814 arguments, check that Lisp number is nonnegative, rather than
3815 silently wrapping negative numbers around. (Bug#8722)
3816 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
3819 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
3821 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
3823 ccl: add integer overflow checks
3824 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
3825 (IN_INT_RANGE): New macros.
3826 (ccl_driver): Use them to check for integer overflow when
3827 decoding a CCL program. Many of the new checks are whether XINT (x)
3828 fits in int; it doesn't always, on 64-bit hosts. The new version
3829 doesn't catch all possible integer overflows, but it's an
3830 improvement. (Bug#8719)
3832 * alloc.c (make_event_array): Use XINT, not XUINT.
3833 There's no need for unsigned here.
3835 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
3836 This follows up to the 2011-05-06 change that substituted uintptr_t
3837 for EMACS_INT. This case wasn't caught back then.
3839 Rework Fformat to avoid integer overflow issues.
3840 * editfns.c: Include <float.h> unconditionally, as it's everywhere
3841 now (part of C89). Include <verify.h>.
3842 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
3843 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
3844 (Fformat): Avoid the prepass trying to compute sizes; it was only
3845 approximate and thus did not catch overflow reliably. Instead, walk
3846 through the format just once, formatting and computing sizes as we go,
3847 checking for integer overflow at every step, and allocating a larger
3848 buffer as needed. Keep track separately whether the format is
3849 multibyte. Keep only the most-recently calculated precision, rather
3850 than them all. Record whether each argument has been converted to
3851 string. Use EMACS_INT, not int, for byte and char and arg counts.
3852 Support field widths and precisions larger than INT_MAX. Avoid
3853 sprintf's undefined behavior with conversion specifications such as %#d
3854 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
3855 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
3856 formatting out-of-range floating point numbers with int
3859 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
3861 * data.c: Avoid integer truncation in expressions involving floats.
3862 * data.c: Include <intprops.h>.
3863 (arith_driver): When there's an integer overflow in an expression
3864 involving floating point, convert the integers to floating point
3865 so that the resulting value does not suffer from catastrophic
3866 integer truncation. For example, on a 64-bit host (* 4
3867 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
3868 Do not rely on undefined behavior after integer overflow.
3870 merge count_size_as_multibyte, parse_str_to_multibyte
3871 * character.c, character.h (count_size_as_multibyte):
3872 Rename from parse_str_to_multibyte; all uses changed.
3873 Check for integer overflow.
3874 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
3875 since it's now a duplicate of the other. This is more of
3876 a character than a buffer op, so better that it's in character.c.
3877 * fns.c, print.c: Adjust to above changes.
3879 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
3881 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
3883 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3885 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3886 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
3887 (x_clipboard_manager_save): Now static.
3888 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
3890 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3891 (crypto_hash_function): Now static.
3892 Fix pointer signedness problems. Avoid unnecessary initializations.
3894 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
3896 * termhooks.h (Vselection_alist): Make it terminal-local.
3898 * terminal.c (create_terminal): Initialize it.
3900 * xselect.c: Support for clipboard managers.
3901 (Vselection_alist): Move to termhooks.h as terminal-local var.
3902 (LOCAL_SELECTION): New macro.
3903 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
3904 (symbol_to_x_atom): Remove gratuitous arg.
3905 (x_handle_selection_request, lisp_data_to_selection_data)
3906 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
3907 (x_own_selection, x_get_local_selection, x_convert_selection):
3908 New arg, specifying work frame. Use terminal-local Vselection_alist.
3909 (some_frame_on_display): Delete unused function.
3910 (Fx_own_selection_internal, Fx_get_selection_internal)
3911 (Fx_disown_selection_internal, Fx_selection_owner_p)
3912 (Fx_selection_exists_p): New optional frame arg.
3913 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
3914 (x_handle_selection_clear): Don't treat other terminals with the
3915 same keyboard specially. Use the terminal-local Vselection_alist.
3916 (x_clear_frame_selections): Use Frun_hook_with_args.
3918 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
3920 * xterm.h: Add support for those atoms.
3922 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
3924 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
3925 (converted_selections, conversion_fail_tag): New global variables.
3926 (x_selection_request_lisp_error): Free the above.
3927 (x_get_local_selection): Remove unnecessary code.
3928 (x_reply_selection_request): Args changed; handle arbitrary array
3929 of converted selections stored in converted_selections.
3930 Separate the XChangeProperty and SelectionNotify steps.
3931 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
3932 (x_convert_selection): New function.
3933 (x_handle_selection_event): Simplify.
3934 (x_get_foreign_selection): Don't ignore incoming requests while
3935 waiting for an answer; this will fail when we implement
3936 SAVE_TARGETS, and seems unnecessary anyway.
3937 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
3938 (Vx_sent_selection_functions): Doc fix.
3940 2011-05-26 Leo Liu <sdl.web@gmail.com>
3942 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
3944 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3946 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
3948 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
3949 for fringe update if it has periodic bitmap.
3950 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
3951 and fringe_bitmap_periodic_p.
3953 * fringe.c (get_fringe_bitmap_data): New function.
3954 (draw_fringe_bitmap_1, update_window_fringes): Use it.
3955 (update_window_fringes): Record periodicity of fringe bitmap in glyph
3956 row. Mark glyph row for fringe update if periodicity changed.
3958 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
3959 for fringe update unless it has periodic bitmap.
3961 2011-05-25 Kenichi Handa <handa@m17n.org>
3963 * xdisp.c (get_next_display_element): Set correct it->face_id for
3964 a static composition.
3966 2011-05-24 Leo Liu <sdl.web@gmail.com>
3969 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
3971 * fns.c (crypto_hash_function, Fsha1): New function.
3972 (Fmd5): Use crypto_hash_function.
3973 (syms_of_fns): Add Ssha1.
3975 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3977 * gnutls.c: Remove unused macros.
3978 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
3979 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
3980 Remove macros that are defined and never used.
3981 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
3983 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3985 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
3986 (Fx_get_selection_internal): Minor cleanup.
3987 (Fx_own_selection_internal): Rename arguments for consistency with
3990 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3992 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
3994 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3996 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
3998 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4000 * dispnew.c (scrolling_window): Don't exclude the case that the
4001 last enabled row in the desired matrix touches the bottom boundary.
4003 2011-05-21 Glenn Morris <rgm@gnu.org>
4005 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
4006 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
4007 and add some more files.
4009 2011-05-20 Eli Zaretskii <eliz@gnu.org>
4011 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
4012 report_file_error introduced by the change from 2011-05-07.
4014 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
4016 * systime.h (Time): Define only if emacs is defined.
4017 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
4018 where the include path doesn't have X11/X.h by default. See
4019 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
4021 2011-05-20 Kenichi Handa <handa@m17n.org>
4023 * composite.c (find_automatic_composition): Fix previous change.
4025 2011-05-20 Glenn Morris <rgm@gnu.org>
4027 * lisp.mk: New file, split from Makefile.in.
4028 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
4029 (shortlisp): Remove.
4030 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
4032 2011-05-19 Glenn Morris <rgm@gnu.org>
4034 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
4035 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
4036 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
4037 (lisp): Set the order to that of loadup.el.
4038 (shortlisp): Make it a copy of $lisp.
4039 (SOME_MACHINE_LISP): Remove.
4040 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
4041 Use just $shortlisp, not $SOME_MACHINE_LISP too.
4043 2011-05-18 Kenichi Handa <handa@m17n.org>
4045 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
4046 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
4047 (find_automatic_composition): Mostly rewrite for efficiency.
4049 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
4051 * makefile.w32-in: Update dependencies.
4053 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
4055 * menu.c: Include limits.h (fixes the MS-Windows build broken by
4056 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
4058 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
4060 Fix some integer overflow issues, such as string length overflow.
4062 * insdel.c (count_size_as_multibyte): Check for string overflow.
4064 * character.c (lisp_string_width): Check for string overflow.
4065 Use EMACS_INT, not int, for string indexes and lengths; in
4066 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
4067 the resulting string length overflows an EMACS_INT; instead,
4068 report a string overflow if no precision given. When checking for
4069 precision exhaustion, use a check that cannot possibly have
4070 integer overflow. (Bug#8675)
4071 * character.h (lisp_string_width): Adjust to new signature.
4073 * alloc.c (string_overflow): New function.
4074 (Fmake_string): Use it. This doesn't change behavior, but saves
4075 a few bytes and will simplify future changes.
4076 * character.c (string_escape_byte8): Likewise.
4077 * lisp.h (string_overflow): New decl.
4079 Fixups, following up to the user-interface timestamp change.
4080 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
4081 for UI timestamps, instead of unsigned long.
4082 * msdos.c (mouse_get_pos): Likewise.
4083 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
4084 * w32gui.h (Time): Define by including "systime.h" rather than by
4085 declaring it ourselves. (Bug#8664)
4087 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
4088 * image.c (clear_image_cache): Likewise.
4090 * term.c (term_mouse_position): Don't assume time_t wraparound.
4092 Be more systematic about user-interface timestamps.
4093 Before, the code sometimes used 'Time', sometimes 'unsigned long',
4094 and sometimes 'EMACS_UINT', to represent these timestamps.
4095 This change causes it to use 'Time' uniformly, as that's what X uses.
4096 This makes the code easier to follow, and makes it easier to catch
4097 integer overflow bugs such as Bug#8664.
4098 * frame.c (Fmouse_position, Fmouse_pixel_position):
4099 Use Time, not unsigned long, for user-interface timestamps.
4100 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
4101 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
4102 * keyboard.h (last_event_timestamp): Likewise.
4103 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
4104 * menu.h (xmenu_show): Likewise.
4105 * term.c (term_mouse_position): Likewise.
4106 * termhooks.h (struct input_event.timestamp): Likewise.
4107 (struct terminal.mouse_position_hook): Likewise.
4108 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
4109 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
4110 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
4111 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
4113 * menu.h, termhooks.h: Include "systime.h", for Time.
4115 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
4116 Don't assume that the difference between two unsigned long values
4117 can fit into an integer. At this point, we know button_down_time
4118 <= event->timestamp, so the difference must be nonnegative, so
4119 there's no need to cast the result if double-click-time is
4120 nonnegative, as it should be; check that it's nonnegative, just in
4121 case. This bug is triggered when events are more than 2**31 ms
4122 apart (about 25 days). (Bug#8664)
4124 * xselect.c (last_event_timestamp): Remove duplicate decl.
4125 (x_own_selection): Remove needless cast to unsigned long.
4127 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
4128 that always fit in int. Use a sentinel instead of a counter, to
4129 avoid a temp and to allay GCC's concerns about possible int overflow.
4130 * frame.h (struct frame): Use int for menu_bar_items_used
4131 instead of EMACS_INT, since it always fits in int.
4133 * menu.c (grow_menu_items): Check for int overflow.
4135 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
4137 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
4138 Before, the code was not consistent. These values cannot exceed
4139 2**31 - 1 so there's no need to make them unsigned.
4140 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
4141 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
4142 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
4144 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
4146 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
4147 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
4148 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
4149 presumably because the widths might not match.
4151 * window.c (size_window): Avoid needless test at loop start.
4153 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
4155 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
4157 2011-05-12 Drew Adams <drew.adams@oracle.com>
4159 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
4161 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4163 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
4164 `width' to `bar_area_x' and `bar_area_width', respectively.
4165 (x_scroll_run): Take account of fringe background extension.
4167 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
4168 Rename local vars `left' and `width' to `bar_area_x' and
4169 `bar_area_width', respectively.
4170 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
4171 background extension.
4173 2011-05-10 Jim Meyering <meyering@redhat.com>
4175 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
4177 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
4179 * image.c (Finit_image_library): Return t for built-in image types,
4180 like pbm and xbm. (Bug#8640)
4182 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
4184 * w32menu.c (set_frame_menubar): Fix submenu allocation.
4186 2011-05-07 Eli Zaretskii <eliz@gnu.org>
4188 * w32console.c (Fset_screen_color): Doc fix.
4189 (Fget_screen_color): New function.
4190 (syms_of_ntterm): Defsubr it.
4192 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
4193 unlink the temporary file if Fcall_process didn't create it in the
4195 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
4196 child process will be redirected to a file specified with `:file'.
4197 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
4198 cue to call_process_cleanup not to close that handle.
4200 2011-05-07 Ben Key <bkey76@gmail.com>
4202 * makefile.w32-in: The bootstrap-temacs rule now makes use of
4203 one of two shell specific rules, either bootstrap-temacs-CMD or
4204 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
4205 to the previous implementation of the bootstrap-temacs rule.
4206 The bootstrap-temacs-CMD rule is similar to the previous
4207 implementation of the bootstrap-temacs rule except that it
4208 makes use of the ESC_CFLAGS variable instead of the CFLAGS
4211 These changes, along with some changes to nt/configure.bat,
4212 nt/gmake.defs, and nt/nmake.defs, are required to extend my
4213 earlier fix to add support for --cflags and --ldflags options
4214 that include quotes so that it works whether make uses cmd or
4217 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
4219 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
4220 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
4222 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
4223 a string. Handle both cases.
4224 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
4225 (Fdbus_register_method): Use Qinvalid_function.
4227 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
4229 * makefile.w32-in: Update dependencies.
4230 (LISP_H): Add inttypes.h and stdin.h.
4231 (PROCESS_H): Add unistd.h.
4233 2011-05-06 Eli Zaretskii <eliz@gnu.org>
4235 * lread.c: Include limits.h (fixes the MS-Windows build broken by
4236 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
4238 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
4240 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
4242 * term.c (vfatal): Remove stray call to va_end.
4243 It's not needed and the C Standard doesn't allow it here anyway.
4245 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
4246 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
4248 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
4251 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
4253 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
4255 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
4257 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
4259 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
4261 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
4262 * charset.c (Fdefine_charset_internal): Don't initialize
4263 charset.code_space[15]. The value was garbage, on hosts with
4264 32-bit int (Bug#8600).
4266 * lread.c (read_integer): Be more consistent with string-to-number.
4267 Use string_to_number to do the actual conversion; this avoids
4268 rounding errors and fixes some other screwups. Without this fix,
4269 for example, #x1fffffffffffffff was misread as -2305843009213693952.
4270 (digit_to_number): Move earlier, for benefit of read_integer.
4271 Return -1 if the digit is out of range for the base, -2 if it is
4272 not a digit in any supported base. (Bug#8602)
4274 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
4276 * dispnew.c (scrolling_window): Return 1 if we scrolled,
4277 to match comment at start of function. This also removes a
4278 GCC warning about overflow in a 32+64-bit port.
4280 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
4282 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
4283 Reported by Stefan Monnier in
4284 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
4285 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
4286 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
4288 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
4289 (EMACS_UINTPTR): Likewise, with uintptr_t.
4291 * lisp.h: Prefer 64-bit EMACS_INT if available.
4292 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
4293 on 32-bit hosts that have 64-bit int, so that they can access
4295 However, temporarily disable this change unless the temporary
4296 symbol WIDE_EMACS_INT is defined.
4298 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
4300 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
4301 This removes an assumption that EMACS_INT and long are the same
4302 width as pointers. The assumption is true for Emacs porting targets
4303 now, but we want to make other targets possible.
4304 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
4305 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
4306 In the rest of the code, change types of integers that hold casted
4307 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
4308 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
4309 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
4310 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
4311 No need to cast type when ORing.
4312 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
4313 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
4314 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
4315 assume EMACS_INT is the same width as char *.
4316 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
4317 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
4318 Remove no-longer-needed casts.
4319 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
4320 (xg_tool_bar_help_callback, xg_make_tool_item):
4321 Use EMACS_INTPTR to hold an integer
4322 that will be cast to void *; this can avoid a GCC warning
4323 if EMACS_INT is not the same width as void *.
4324 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
4325 * xdisp.c (display_echo_area_1, resize_mini_window_1):
4326 (current_message_1, set_message_1):
4327 Use a local to convert to proper width without a cast.
4328 * xmenu.c (dialog_selection_callback): Likewise.
4330 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
4331 Also, don't assume VALBITS / RAND_BITS is less than 5,
4332 and don't rely on undefined behavior when shifting a 1 left into
4334 * lisp.h (get_random): Change signature to match.
4336 * lread.c (hash_string): Use size_t, not int, for hash computation.
4337 Normally we prefer signed values; but hashing is special, because
4338 it's better to use unsigned division on hash table sizes so that
4339 the remainder is nonnegative. Also, size_t is the natural width
4340 for hashing into memory. The previous code used 'int', which doesn't
4341 retain enough info to hash well into very large tables.
4342 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
4344 * dbusbind.c: Don't possibly lose pointer info when converting.
4345 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
4346 Use XPNTR rather than XHASH, so that the high-order bits of
4347 the pointer aren't lost when converting through void *.
4349 * eval.c (Fautoload): Don't double-shift a pointer.
4351 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
4353 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
4355 * gnutls.c (DEF_GNUTLS_FN):
4356 * image.c (DEF_IMGLIB_FN): Make function pointers static.
4358 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
4360 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
4363 2011-05-05 Eli Zaretskii <eliz@gnu.org>
4365 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
4366 New version that can reserve upto 2GB of heap space.
4368 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
4370 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
4372 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
4374 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
4375 `gnutls_certificate_set_x509_key_file'.
4377 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
4379 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
4380 Update dependencies.
4382 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4384 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
4385 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
4386 Remove unused parameter `fildes'.
4387 * process.c (read_process_output, send_process): Don't pass it.
4389 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4391 Fix previous change: the library cache is defined in w32.c.
4392 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
4393 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
4395 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4397 Implement dynamic loading of GnuTLS on Windows.
4399 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
4400 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
4401 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
4404 * gnutls.c (Qgnutls_dll): Define.
4405 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
4406 (gnutls_*): Declare function pointers.
4407 (init_gnutls_functions): New function to initialize function pointers.
4408 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
4409 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
4410 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
4411 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
4412 (emacs_gnutls_write, emacs_gnutls_read)
4413 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
4414 (Fgnutls_available_p): New function.
4415 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
4416 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
4417 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
4419 * image.c: Include w32.h.
4420 (Vimage_type_cache): Delete.
4421 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
4422 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
4423 (w32_delayed_load): Move to w32.c.
4425 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
4427 * w32.c (QCloaded_from, Vlibrary_cache): Define.
4428 (w32_delayed_load): Move from image.c. When loading a library, record
4429 its filename in the :loaded-from property of the library id.
4430 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
4431 Initialize and staticpro them.
4432 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
4434 * process.c: Include lisp.h before w32.h, not after.
4435 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
4436 instead of gnutls_record_check_pending.
4438 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
4440 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
4442 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
4443 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
4446 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
4448 * xterm.c (x_set_frame_alpha): Do not set property on anything
4449 else than FRAME_X_OUTER_WINDOW (Bug#8608).
4451 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
4453 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
4455 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
4457 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
4458 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

4464 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
4465 (Qgnutls_bootprop_callbacks_verify): Make static.
4467 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
4469 * callproc.c: Indentation fixup.
4471 * sysdep.c (wait_for_termination_1): Make static.
4472 (wait_for_termination, interruptible_wait_for_termination):
4473 Move after wait_for_termination_1.
4475 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
4477 * sysdep.c (interruptible_wait_for_termination): New function
4478 which is like wait_for_termination, but allows keyboard
4481 * callproc.c (Fcall_process): Add (:file "file") as an option for
4483 (Fcall_process_region): Ditto.
4485 2011-04-30 Eli Zaretskii <eliz@gnu.org>
4487 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
4488 rather than `XVECTOR (FOO)->size'.
4490 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
4491 inttypes.h, as a gnulib replacement is used if it not available in
4494 2011-04-21 Eli Zaretskii <eliz@gnu.org>
4496 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
4497 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
4498 of MOST_POSITIVE_FIXNUM. (Bug#8528)
4500 * coding.c (coding_alloc_by_realloc): Error out if destination
4501 will grow beyond MOST_POSITIVE_FIXNUM.
4502 (decode_coding_emacs_mule): Abort if there isn't enough place in
4503 charbuf for the composition carryover bytes. Reserve an extra
4504 space for up to 2 characters produced in a loop.
4505 (decode_coding_iso_2022): Abort if there isn't enough place in
4506 charbuf for the composition carryover bytes.
4508 2011-04-21 Eli Zaretskii <eliz@gnu.org>
4510 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
4511 aborting when %lld or %lll format is passed.
4512 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
4513 %llo or %llx format is passed. (Bug#8545)
4515 * window.c (window_scroll_line_based): Use a marker instead of
4516 simple variables to record original value of point. (Bug#7952)
4518 * doprnt.c (doprnt): Fix the case where a multibyte sequence
4519 produced by %s or %c overflows available buffer space. (Bug#8545)
4521 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
4523 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
4524 (SIZE_MAX): Move defn after all includes, as they might #define it.
4526 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4528 * w32.c (init_environment): Warn about defaulting HOME to C:\.
4530 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4532 * keyboard.c (Qdelayed_warnings_hook): Define.
4533 (command_loop_1): Run `delayed-warnings-hook'
4534 if Vdelayed_warnings_list is non-nil.
4535 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
4536 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
4538 2011-04-28 Eli Zaretskii <eliz@gnu.org>
4540 * doprnt.c (doprnt): Don't return value smaller than the buffer
4541 size if the message was truncated. (Bug#8545).
4543 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4545 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

4548 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
4550 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
4552 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
4554 * makefile.w32-in: Update dependencies.
4556 2011-04-27 Eli Zaretskii <eliz@gnu.org>
4558 Improve `doprnt' and its usage. (Bug#8545)
4559 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
4560 `format_end'. Remove support for %l as a conversion specifier.
4561 Don't use xrealloc. Improve diagnostics when the %l size modifier
4562 is used. Update the commentary.
4564 * eval.c (verror): Simplify calculation of size_t.
4566 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
4569 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
4571 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
4574 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
4576 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
4577 This makes this file independent of the recent pseudovector change.
4579 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
4581 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
4583 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
4584 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
4585 Remove unused local.
4586 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
4588 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
4589 GCC 4.6.0 optimizes based on type-based alias analysis.
4590 For example, if b is of type struct buffer * and v of type struct
4591 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
4592 != &v->size, and therefore "v->size = 1; b->size = 2; return
4593 v->size;" must therefore return 1. This assumption is incorrect
4594 for Emacs, since it type-puns struct Lisp_Vector * with many other
4595 types. To fix this problem, this patch adds a new type struct
4596 vectorlike_header that documents the constraints on layout of vectors
4597 and pseudovectors, and helps optimizing compilers not get fooled
4598 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
4599 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
4600 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
4602 (XSETPVECTYPE): Rewrite in terms of new macro.
4603 (XSETPVECTYPESIZE): New macro, specifying both type and size.
4604 This is a bit clearer, and further avoids the possibility of
4605 undesirable aliasing.
4606 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
4607 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
4608 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
4609 since Lisp_Subr is a special case (no "next" field).
4610 (ASIZE): Now uses header.size rather than size.
4611 All previous uses of XVECTOR (foo)->size replaced to use this macro,
4612 to avoid the hassle of writing XVECTOR (foo)->header.size.
4613 (struct vectorlike_header): New type.
4614 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
4615 object, to help avoid aliasing.
4616 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
4617 (SUBRP): Likewise, since Lisp_Subr is a special case.
4618 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
4619 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
4620 (struct Lisp_Hash_Table): Combine first two members into a single
4621 struct vectorlike_header member. All uses of "size" and "next" members
4622 changed to be "header.size" and "header.next".
4623 * buffer.h (struct buffer): Likewise.
4624 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
4625 * frame.h (struct frame): Likewise.
4626 * process.h (struct Lisp_Process): Likewise.
4627 * termhooks.h (struct terminal): Likewise.
4628 * window.c (struct save_window_data, struct saved_window): Likewise.
4629 * window.h (struct window): Likewise.
4630 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
4631 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
4632 * buffer.c (init_buffer_once): Likewise.
4633 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
4635 * process.c (Fformat_network_address): Use local var for size,
4638 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
4640 Make the Lisp reader and string-to-float more consistent (Bug#8525)
4641 * data.c (atof): Remove decl; no longer used or needed.
4642 (digit_to_number): Move to lread.c.
4643 (Fstring_to_number): Use new string_to_number function, to be
4644 consistent with how the Lisp reader treats infinities and NaNs.
4645 Do not assume that floating-point numbers represent EMACS_INT
4646 without losing information; this is not true on most 64-bit hosts.
4647 Avoid double-rounding errors, by insisting on integers when
4648 parsing non-base-10 numbers, as the documentation specifies.
4649 * lisp.h (string_to_number): New decl, replacing ...
4650 (isfloat_string): Remove.
4651 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
4652 (read1): Do not accept +. and -. as integers; this
4653 appears to have been a coding error. Similarly, do not accept
4654 strings like +-1e0 as floating point numbers. Do not report
4655 overflow for integer overflows unless the base is not 10 which
4656 means we have no simple and reliable way to continue.
4657 Break out the floating-point parsing into a new
4658 function string_to_number, so that Fstring_to_number parses
4659 floating point numbers consistently with the Lisp reader.
4660 (digit_to_number): Move here from data.c. Make it static inline.
4661 (E_CHAR, EXP_INT): Remove, replacing with ...
4662 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
4663 (string_to_number): New function, replacing isfloat_string.
4664 This function checks for valid syntax and produces the resulting
4665 Lisp float number too. Rework it so that string-to-number
4666 no longer mishandles examples like "1.0e+". Use strtoumax,
4667 so that overflow for non-base-10 numbers is reported only when
4668 there's no portable and simple way to convert to floating point.
4670 * textprop.c (set_text_properties_1): Rewrite for clarity,
4671 and to avoid GCC warning about integer overflow.
4673 * intervals.h (struct interval): Use EMACS_INT for members
4674 where EMACS_UINT might cause problems. See
4675 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
4676 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
4677 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
4679 (offset_intervals): Tell GCC not to worry about length overflow
4680 when negating a negative length.
4682 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
4683 (overrun_check_free): Likewise.
4685 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
4686 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
4689 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4690 (gnutls_make_error): Rename local to avoid shadowing.
4691 (gnutls_emacs_global_deinit): ifdef out; not used.
4692 (Fgnutls_boot): Use const for pointer to readonly storage.
4693 Comment out unused local. Fix pointer signedness problems.
4695 * lread.c (openp): Don't stuff size_t into an 'int'.
4696 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
4697 about possible signed overflow.
4699 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4700 (GDK_KEY_g): Don't define if already defined.
4701 (xg_prepare_tooltip): Avoid pointer signedness problem.
4702 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
4704 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
4705 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
4707 * xfns.c (Fx_window_property): Simplify a bit,
4708 to make a bit faster and to avoid GCC 4.6.0 warning.
4709 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
4711 * fns.c (internal_equal): Don't assume size_t fits in int.
4713 * alloc.c (compact_small_strings): Tighten assertion a little.
4715 Replace pEd with more-general pI, and fix some printf arg casts.
4716 * lisp.h (pI): New macro, generalizing old pEd macro to other
4717 conversion specifiers. For example, use "...%"pI"d..." rather
4718 than "...%"pEd"...".
4719 (pEd): Remove. All uses replaced with similar uses of pI.
4720 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
4721 * alloc.c (check_pure_size): Don't overflow by converting size to int.
4722 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
4723 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
4724 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
4725 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
4726 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
4728 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
4729 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
4730 * print.c (safe_debug_print, print_object): Likewise.
4731 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
4733 Use pI instead of if-then-else-abort. Use %p to avoid casts,
4734 avoiding the 0 flag, which is not portable.
4735 * process.c (Fmake_network_process): Use pI to avoid cast.
4736 * region-cache.c (pp_cache): Likewise.
4737 * xdisp.c (decode_mode_spec): Likewise.
4738 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
4739 behavior on 64-bit hosts with printf arg.
4740 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
4741 (x_stop_queuing_selection_requests): Likewise.
4742 (x_get_window_property): Don't truncate byte count to an 'int'
4745 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
4746 here, since it parses constructs like leading '-' and spaces,
4747 which are not wanted; and it overflows with large numbers.
4748 Instead, simply match F[0-9]+, which is what is wanted anyway.
4750 * alloc.c: Remove unportable assumptions about struct layout.
4751 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
4752 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
4753 (allocate_vectorlike, make_pure_vector): Use the new macros,
4754 plus offsetof, to remove unportable assumptions about struct layout.
4755 These assumptions hold on all porting targets that I know of, but
4756 they are not guaranteed, they're easy to remove, and removing them
4757 makes further changes easier.
4759 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
4760 This doesn't fix a bug but makes the code clearer.
4761 (string_overrun_cookie): Now const. Use initializers that
4762 don't formally overflow signed char, to avoid warnings.
4763 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
4764 can cause Emacs to crash when string overrun checking is enabled.
4765 (allocate_buffer): Don't assume sizeof (struct buffer) is a
4766 multiple of sizeof (EMACS_INT); it need not be, if
4767 alignof(EMACS_INT) < sizeof (EMACS_INT).
4768 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
4770 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
4772 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
4774 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>

4790 * alloc.c (check_sblock, check_string_bytes)
4791 (check_string_free_list): Convert to standard C.
4793 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
4795 * w32.c (emacs_gnutls_push): Fix typo.
4797 2011-04-25 Eli Zaretskii <eliz@gnu.org>
4799 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
4800 "cast to pointer from integer of different size".
4802 Improve doprnt and its use in verror. (Bug#8545)
4803 * doprnt.c (doprnt): Document the set of format control sequences
4804 supported by the function. Use SAFE_ALLOCA instead of always
4807 * eval.c (verror): Don't limit the buffer size at size_max-1, that
4808 is one byte too soon. Don't use xrealloc; instead xfree and
4811 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
4813 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
4816 * gnutls.c: Renamed global_initialized to
4817 gnutls_global_initialized. Added internals for the
4818 :verify-hostname-error, :verify-error, and :verify-flags
4819 parameters of `gnutls-boot' and documented those parameters in the
4820 docstring. Start callback support.
4821 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
4822 unless a fatal error occurred. Call gnutls_alert_send_appropriate
4823 on error. Return error code.
4824 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
4825 (emacs_gnutls_read): Likewise.
4826 (Fgnutls_boot): Return handshake error code.

4898 Many local variables are now size_t instead of int or unsigned.
4899 Improve overflow protection. Support `l' modifier for integer
4900 conversions. Support %l conversion. Don't assume an EMACS_INT
4901 argument for integer conversions and for %c.

4911 (callint.o): Depend on character.h.
4913 * eval.c (internal_lisp_condition_case): Include the handler
4914 representation in the error message.
4915 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
4916 when breaking from the loop.
4918 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
4920 * callint.c (Fcall_interactively): When displaying error message
4921 about invalid control letter, pass the character's codepoint, not
4922 a pointer to its multibyte form. Improve display of the character
4923 in octal and display also its hex code.
4925 * character.c (char_string): Use %x to display the (unsigned)
4926 codepoint of an invalid character, to avoid displaying a bogus
4929 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
4930 `error', not SYMBOL_NAME itself.

5019 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
5020 so that we aren't warned about unused symbols.
5022 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
5024 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

5031 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
5032 (x_dispatch_event): Declare static if USE_GTK, and
5033 define if USE_GTK || USE_X_TOOLKIT.
5034 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
5035 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
5036 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
5037 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
5039 * xmenu.c (menu_help_callback): Pointer type fixes.
5040 Use const pointers when pointing at readonly data. Avoid pointer

5045 * xfns.c (Fx_hide_tip): Move locals to avoid shadowing.
5047 * menu.c (push_submenu_start, push_submenu_end): Do not define unless

5051 * keyboard.c (make_lispy_event): Remove unused local var.
5053 * frame.c, frame.h (x_get_resource_string): Bring this back, but
5054 only if HAVE_X_WINDOWS && !USE_X_TOOLKIT.
5056 * bitmaps: Change bitmaps from unsigned char back to the X11
5057 compatible char. Avoid the old compiler warnings about
5058 out-of-range initializers by using, for example, '\xab' rather
5061 * xgselect.c (xgselect_initialize): Check vs interface
5062 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).
5064 * xmenu.c (xmenu_show): Rename parm to avoid shadowing.

5127 * nsfont.m: Fixed bugs in ns_get_family and
5128 ns_descriptor_to_entity that were caused by using free to
5129 deallocate memory blocks that were allocated by xmalloc (via
5130 xstrdup). This caused Emacs to crash when compiled with
5131 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
5132 --enable-checking=xmallocoverrun). xfree is now used to
5133 deallocate these memory blocks.

5560 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
5561 Mark functions with DEFUE instead of DEFUN,
5562 if they are used in other modules.

5603 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
5604 when at ZV. (Bug#8487)
5606 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
5608 * charset.c (Fclear_charset_maps): Use xfree instead of free.
5610 * keyboard.c (parse_tool_bar_item): Likewise.
5611 * sound.c (sound_cleanup, alsa_close): Likewise.
5612 * termcap.c (tgetent): Likewise.
5613 * xfns.c (x_default_font_parameter): Likewise.
5614 * xsettings.c (read_and_apply_settings): Likewise.
5616 * alloc.c (overrun_check_malloc, overrun_check_realloc)
5617 (overrun_check_free): Protoize.
5619 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
5621 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
5622 since callers should never pass a negative size.
5623 Change the signature to match that of plain 'read' and 'write'; see
5624 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
5625 * lisp.h: Update prototypes of emacs_write and emacs_read.
5627 2011-04-11 Eli Zaretskii <eliz@gnu.org>
5629 * xdisp.c (redisplay_window): Don't try to determine the character
5630 position of the scroll margin if the window start point w->startp
5631 is outside the buffer's accessible region. (Bug#8468)
5633 2011-04-10 Eli Zaretskii <eliz@gnu.org>
5635 Fix write-region and its subroutines for buffers > 2GB.
5636 * fileio.c (a_write, e_write): Modify declaration of arguments and
5637 local variables to support buffers larger than 2GB.
5638 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
5640 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
5641 argument, local variables, and return value.
5643 * lisp.h: Update prototypes of emacs_write and emacs_read.
5645 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
5647 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
5649 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
5651 Fix more problems found by GCC 4.6.0's static checks.
5653 * xdisp.c (vmessage): Use a better test for character truncation.
5655 * charset.c (load_charset_map): <, not <=, for optimization,
5656 and to avoid potential problems with integer overflow.
5657 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
5658 * casetab.c (set_identity, shuffle): Likewise.
5659 * editfns.c (Fformat): Likewise.
5660 * syntax.c (skip_chars): Likewise.
5662 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
5663 This also lets GCC 4.6.0 generate slightly better loop code.
5665 * callint.c (Fcall_interactively): <, not <=, for optimization.
5666 (Fcall_interactively): Count the number of arguments produced,
5667 not the number of arguments given. This is simpler and lets GCC
5668 4.6.0 generate slightly better code.
5670 * ftfont.c: Distingish more carefully between FcChar8 and char.
5671 The previous code passed unsigned char * to a functions like
5672 strlen and xstrcasecmp that expect char *, which does not
5673 conform to the C standard.
5674 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
5675 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
5676 char * when the C standard requires it.
5678 * keyboard.c (read_char): Remove unused var.
5680 * eval.c: Port to Windows vsnprintf (Bug#8435).
5682 (SIZE_MAX): Define if the headers do not.
5683 (verror): Do not give up if vsnprintf returns a negative count.
5684 Instead, grow the buffer. This ports to Windows vsnprintf, which
5685 does not conform to C99. Problem reported by Eli Zaretskii.
5686 Also, simplify the allocation scheme, by avoiding the need for
5687 calling realloc, and removing the ALLOCATED variable.
5689 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
5691 Remove invocations of doprnt, as Emacs now uses vsnprintf.
5692 But keep the doprint source code for now, as we might revamp it
5693 and use it again (Bug#8435).
5694 * lisp.h (doprnt): Remove.
5695 * Makefile.in (base_obj): Remove doprnt.o.
5696 * deps.mk (doprnt.o): Remove.
5698 error: Print 32- and 64-bit integers portably (Bug#8435).
5699 Without this change, on typical 64-bit hosts error ("...%d...", N)
5700 was used to print both 32- and 64-bit integers N, which relied on
5702 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
5704 * lisp.h (error, verror): Mark as printf-like functions.
5705 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
5706 Report overflow in size calculations when allocating printf buffer.
5707 Do not truncate output string at its first null byte.
5708 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
5709 Truncate the output at a character boundary, since vsnprintf does not
5711 * charset.c (check_iso_charset_parameter): Convert internal
5712 character to string before calling 'error', since %c now has the
5714 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
5715 overflow when computing char to be passed to 'error'. Do not
5716 pass Lisp_Object to 'error'; pass the integer instead.
5717 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
5718 formatted with plain %d.
5720 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
5722 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
5724 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
5726 * xterm.c (x_catch_errors): Remove duplicate declaration.
5728 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
5730 * xdisp.c, lisp.h (message_nolog): Remove; unused.
5732 2011-04-10 Jim Meyering <meyering@redhat.com>
5734 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
5735 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
5736 return ssize_t not "int", and use size_t as the buffer length.
5737 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
5738 * gnutls.h: Update declarations.
5739 * process.c (read_process_output): Use ssize_t, to match.
5740 (send_process): Likewise.
5742 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
5744 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
5746 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
5748 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
5749 Use unsigned char, to match FcChar8 type definition.
5751 * xterm.c (handle_one_xevent):
5752 * xmenu.c (create_and_show_popup_menu):
5753 * xselect.c (x_decline_selection_request)
5754 (x_reply_selection_request): Avoid type-punned deref of X events.
5756 2011-04-09 Eli Zaretskii <eliz@gnu.org>
5758 Fix some uses of `int' instead of EMACS_INT.
5759 * search.c (string_match_1, fast_string_match)
5760 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
5761 (scan_buffer, find_next_newline_no_quit)
5762 (find_before_next_newline, search_command, Freplace_match)
5763 (Fmatch_data): Make some `int' variables be EMACS_INT.
5765 * xdisp.c (display_count_lines): 3rd argument and return value now
5766 EMACS_INT. All callers changed.
5767 (pint2hrstr): Last argument is now EMACS_INT.
5769 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
5770 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

5782 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
5783 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
5785 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
5786 (encode_invocation_designation): Last argument P_NCHARS is now
5788 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
5789 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
5791 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
5794 * ccl.c (Fccl_execute_on_string): Declare some variables
5797 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

5809 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
5811 * keyboard.c (read_char): Call Lisp function help-form-show,
5812 instead of using internal_with_output_to_temp_buffer.

5814 (syms_of_keyboard): Use DEFSYM macro.
5816 * print.c (internal_with_output_to_temp_buffer): Function deleted.
5818 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
5820 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
5822 * process.c (Flist_processes): Remove to Lisp.
5823 (list_processes_1): Delete.

5829 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
5831 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
5833 Fix more problems found by GCC 4.6.0's static checks.
5835 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
5837 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
5839 * lisp.h (message, message_nolog, fatal): Mark as printf-like.

5848 printf-like functions.
5849 (tiff_load): Add casts to remove these marks before passing them
5850 to system-supplied API.
5852 * eval.c (Fsignal): Remove excess argument to 'fatal'.
5854 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
5855 This avoids several warnings with gcc -Wstrict-overflow.
5856 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
5857 directly, rather than having caller test rule sign. This avoids
5858 some unnecessary tests.
5859 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
5860 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
5861 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
5863 * xfont.c (xfont_text_extents): Remove var that was set but not used.
5864 (xfont_open): Avoid unnecessary tests.
5866 * composite.c (composition_gstring_put_cache): Use unsigned integer.

5875 by using the new macro.
5877 * textprop.c (set_text_properties_1): Change while to do-while,
5878 since the condition is always true at first.

5893 * syntax.c (scan_words): Remove var that was set but not used.
5894 (update_syntax_table): Use unsigned instead of int.
5896 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

5906 (font_score): Avoid potential overflow in diff calculation.
5908 * fns.c (substring_both): Remove var that is set but not used.
5909 (sxhash): Redo loop for clarity and to avoid wraparound warning.
5911 * eval.c (funcall_lambda): Rename local to avoid shadowing.
5913 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
5914 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
5915 can always succeed if overflow has undefined behavior.
5917 * search.c (boyer_moore, wordify): Remove vars set but not used.
5918 (wordify): Omit three unnecessary tests.
5920 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
5921 All callers changed. This avoids the need for an unused var.
5923 * casefiddle.c (casify_region): Remove var that is set but not used.
5925 * dired.c (file_name_completion): Remove var that is set but not used.
5927 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
5929 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
5930 (Finsert_file_contents): Remove unnecessary code checking fd.
5932 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
5933 Check for integer overflow on size calculations.
5935 * buffer.c (Fprevious_overlay_change): Remove var that is set
5938 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
5939 Remove vars that are set but not used.

5941 (timer_check_2): Mark vars as initialized.
5943 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
5945 * image.c (lookup_image): Remove var that is set but not used.
5946 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
5948 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
5949 that are set but not used.
5951 * xfns.c (make_invisible_cursor): Don't return garbage
5952 if XCreateBitmapFromData fails (Bug#8410).

5971 * coding.c: Remove vars that are set but not used.
5972 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
5973 All callers changed.
5974 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):

5976 (decode_coding_charset): Remove vars that are set but not used.
5978 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
5979 that is set but not used.
5981 * print.c (print_object): Remove var that is set but not used.
5983 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
5984 The gnulib version avoids calling malloc in the usual case,
5985 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
5986 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
5987 * filelock.c (current_lock_owner): Likewise.
5988 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
5989 * sysdep.c: Include allocator.h, careadlinkat.h.
5990 (emacs_no_realloc_allocator): New static constant.
5991 (emacs_readlink): New function.
5992 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

5995 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
5997 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
5998 first non-nil return value).
6000 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
6002 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
6003 if not defined (Bug#8403).
6005 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
6007 * xdisp.c (display_count_lines): Remove parameter `start',
6008 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
6009 (get_char_face_and_encoding): Remove parameter `multibyte_p',
6010 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

6012 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
6013 and thereabouts. All callers changed.
6014 (get_per_char_metric): Remove parameter `f', unused since
6015 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

6019 do not dereference NULL upon failed strdup
6020 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
6021 (ns_get_family): Likewise.

6025 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
6027 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
6029 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
6032 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
6034 Add lexical binding.
6036 * window.c (Ftemp_output_buffer_show): New fun.
6037 (Fsave_window_excursion):
6038 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
6040 * lread.c (lisp_file_lexically_bound_p): New function.
6041 (Fload): Bind Qlexical_binding.
6042 (readevalloop): Remove `evalfun' arg.
6043 Bind Qinternal_interpreter_environment.
6044 (Feval_buffer): Bind Qlexical_binding.
6045 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
6047 (syms_of_lread): Declare `lexical-binding'.
6049 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
6051 * keyboard.c (eval_dyn): New fun.
6052 (menu_item_eval_property): Use it.
6054 * image.c (parse_image_spec): Use Ffunctionp.
6056 * fns.c (concat, mapcar1): Accept byte-code-functions.
6058 * eval.c (Fsetq): Handle lexical vars.
6059 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
6060 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
6061 (FletX, Flet): Obey lexical binding.
6062 (Fcommandp): Handle closures.
6063 (Feval): New `lexical' arg.
6064 (eval_sub): New function extracted from Feval. Use it almost
6065 everywhere where Feval was used. Look up vars in lexical env.
6067 (Ffunctionp): Move from subr.el.
6068 (Ffuncall): Handle closures.
6069 (apply_lambda): Remove `eval_flags'.
6070 (funcall_lambda): Handle closures and new byte-code-functions.
6071 (Fspecial_variable_p): New function.
6072 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
6073 but without exporting it to Lisp.
6075 * doc.c (Fdocumentation, store_function_docstring):
6076 * data.c (Finteractive_form): Handle closures.
6078 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
6081 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
6083 (exec_byte_code): New function extracted from Fbyte_code to handle new
6084 calling convention for byte-code-functions. Add new byte-codes.
6086 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
6088 * alloc.c (Fmake_symbol): Init new `declared_special' field.
6090 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
6092 * xdisp.c (redisplay_internal): Fix prototype.
6094 2011-03-31 Eli Zaretskii <eliz@gnu.org>
6096 * xdisp.c (SCROLL_LIMIT): New macro.
6097 (try_scrolling): Use it when setting scroll_limit.
6098 Limit scrolling to 100 screen lines.
6099 (redisplay_window): Even when falling back on "recentering",
6100 position point in the window according to scroll-conservatively,
6101 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
6103 (try_scrolling): When point is above the window, allow searching
6104 as far as scroll_max, or one screenful, to compute vertical
6105 distance from PT to the scroll margin position. This prevents
6106 try_scrolling from unnecessarily failing when
6107 scroll-conservatively is set to a value slightly larger than the
6108 window height. Clean up the case of PT below the margin at bottom
6109 of window: scroll_max can no longer be INT_MAX. When aggressive
6110 scrolling is in use, don't let point enter the opposite scroll
6111 margin as result of the scroll.
6112 (syms_of_xdisp) <scroll-conservatively>: Document the
6113 threshold of 100 lines for never-recentering scrolling.
6115 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
6117 * dispextern.h (move_it_by_lines):
6118 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
6119 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
6120 (message_log_check_duplicate): Remove parameters `prev_bol' and
6121 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
6122 (redisplay_internal): Remove parameter `preserve_echo_area',
6123 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
6125 * indent.c (Fvertical_motion):
6126 * window.c (window_scroll_pixel_based, Frecenter):
6127 Don't pass `need_y_p' to `move_it_by_lines'.
6129 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
6131 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
6132 steal a few bits to be more compact.
6133 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
6134 Remove unneeded casts.
6136 * bytecode.c (Fbyte_code): CAR and CDR can GC.
6138 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
6140 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
6141 binding" message (bug#7967).
6143 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
6145 Fix more problems found by GCC 4.6.0's static checks.
6147 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
6148 Remove unused local var.
6150 * editfns.c (Fmessage_box): Remove unused local var.
6152 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
6153 (note_mode_line_or_margin_highlight, note_mouse_highlight):
6154 Omit unused local vars.
6155 * window.c (shrink_windows): Omit unused local var.
6156 * menu.c (digest_single_submenu): Omit unused local var.
6157 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
6158 Omit unused local var.
6160 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
6161 Don't assume string length fits in int.
6162 (keyremap_step, read_key_sequence): Use size_t for sizes.
6163 (read_key_sequence): Don't check last_real_key_start redundantly.
6165 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
6166 instead of alloca (Bug#8344).
6168 * eval.c (Fbacktrace): Don't assume nargs fits in int.
6169 (Fbacktrace_frame): Don't assume nframes fits in int.
6171 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
6173 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
6176 * term.c (produce_glyphless_glyph): Remove unnecessary test.
6178 * cm.c (calccost): Turn while-do into do-while, for clarity.
6180 * keyboard.c (syms_of_keyboard): Use the same style as later
6181 in this function when indexing through an array. This also
6182 works around GCC bug 48267.
6184 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
6186 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
6188 * chartab.c (sub_char_table_ref_and_range): Redo for slight
6189 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
6191 * keyboard.c, keyboard.h (num_input_events): Now size_t.
6192 This avoids undefined behavior on integer overflow, and is a bit
6193 more convenient anyway since it is compared to a size_t variable.
6195 Variadic C functions now count arguments with size_t, not int.
6196 This avoids an unnecessary limitation on 64-bit machines, which
6197 caused (substring ...) to crash on large vectors (Bug#8344).
6198 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
6199 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
6200 All variadic functions and their callers changed accordingly.
6201 (struct gcpro.nvars): Now size_t, not int. All uses changed.
6202 * data.c (arith_driver, float_arith_driver): Likewise.
6203 * editfns.c (general_insert_function): Likewise.
6204 * eval.c (struct backtrace.nargs, interactive_p)
6205 (internal_condition_case_n, run_hook_with_args, apply_lambda)
6206 (funcall_lambda, mark_backtrace): Likewise.
6207 * fns.c (concat): Likewise.
6208 * frame.c (x_set_frame_parameters): Likewise.
6209 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
6210 0 if not found, not -1. All callers changed.
6212 * alloc.c (garbage_collect): Don't assume stack size fits in int.
6213 (stack_copy_size): Now size_t, not int.
6214 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
6216 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
6218 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
6219 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
6220 All callers changed.
6222 * lisp.h (multibyte_char_to_unibyte):
6223 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
6224 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
6225 * character.h (CHAR_TO_BYTE8):
6226 * cmds.c (internal_self_insert):

6228 * keymap.c (push_key_description):
6229 * search.c (Freplace_match):
6230 * xdisp.c (message_dolog, set_message_1): All callers changed.
6232 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
6234 * keyboard.c (safe_run_hook_funcall): New function.
6235 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
6236 don't set the hook to nil, but remove the offending function instead.
6237 (Qcommand_hook_internal): Remove, unused.
6238 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
6239 Vcommand_hook_internal.
6241 * eval.c (enum run_hooks_condition): Remove.
6242 (funcall_nil, funcall_not): New functions.
6243 (run_hook_with_args): Call each function through a `funcall' argument.
6244 Remove `cond' argument, now redundant.
6245 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
6246 (Frun_hook_with_args_until_failure): Adjust accordingly.
6247 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

6253 * print.c (strout): Remove parameter `multibyte', unused since
6254 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
6256 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
6257 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
6258 All callers changed.
6260 * w32.c (_wsa_errlist): Use braces for struct initializers.
6262 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
6263 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
6264 All callers changed.
6265 (string_buffer_position): Likewise. Also, make static (it's never
6266 used outside xdisp.c).
6267 (cursor_row_p): Remove parameter `w', unused since
6268 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.
6269 (decode_mode_spec): Remove parameter `precision', introduced during
6270 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
6271 All callers changed.
6273 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
6275 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

6296 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
6297 Replace SIGTYPE with void everywhere.

6308 * w32.c (read_unc_volume): Use parameter `henum', instead of
6309 global variable `wget_enum_handle'.
6311 * keymap.c (describe_vector): Remove parameters `indices' and
6312 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
6313 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
6315 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
6317 * keyboard.c (timer_check): Remove parameter `do_it_now',
6318 unused since 1996-04-12T06:01:29Z!rms@gnu.org.

6323 * w32menu.c (w32_menu_display_help):
6324 * xmenu.c (show_help_event, menu_help_callback):

6328 * keyboard.c (readable_events):
6329 * process.c (wait_reading_process_output):
6330 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
6332 * insdel.c (adjust_markers_gap_motion):
6333 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
6334 (gap_left, gap_right): Don't call it.
6336 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
6338 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
6339 incurred during fontification.
6341 2011-03-25 Juanma Barranquero <lekktu@gmail.com>
6343 * buffer.c (defvar_per_buffer): Remove unused parameter `doc'.

6407 2011-03-23 Julien Danjou <julien@danjou.info>
6409 * term.c (Fsuspend_tty, Fresume_tty):
6410 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
6411 * window.c (temp_output_buffer_show):
6412 * insdel.c (signal_before_change):
6413 * frame.c (Fhandle_switch_frame):

6417 * cmds.c (internal_self_insert):
6418 * callint.c (Fcall_interactively):
6419 * buffer.c (Fkill_all_local_variables):
6420 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
6422 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
6423 unconditionnaly since it does the check itself.
6425 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
6427 Fix more problems found by GCC 4.5.2's static checks.
6429 * coding.c (encode_coding_raw_text): Avoid unnecessary test
6430 the first time through the loop, since we know p0 < p1 then.
6431 This also avoids a gcc -Wstrict-overflow warning.
6433 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
6434 leading to a memory leak, possible in functions like
6435 load_charset_map_from_file that can allocate an unbounded number
6436 of objects (Bug#8318).
6438 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
6439 that could (at least in theory) be that large.
6441 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
6442 This is less likely to overflow, and avoids undefined behavior if
6443 overflow does occur. All callers changed. Use strtoul to scan
6444 for the unsigned long integer.
6445 (pint2hrstr): Simplify and tune code slightly.
6446 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
6448 * scroll.c (do_scrolling): Work around GCC bug 48228.
6449 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
6451 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
6452 This also avoids a warning with gcc -Wstrict-overflow.
6453 (validate_x_resource_name): Simplify count usage.
6454 This also avoids a warning with gcc -Wstrict-overflow.
6456 * fileio.c (Fcopy_file): Report error if fchown or fchmod
6459 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
6461 * process.c (Fmake_network_process): Use socklen_t, not int,
6462 where POSIX says socklen_t is required in portable programs.
6463 This fixes a porting bug on hosts like 64-bit HP-UX, where
6464 socklen_t is wider than int (Bug#8277).
6465 (Fmake_network_process, server_accept_connection):
6466 (wait_reading_process_output, read_process_output):
6469 * process.c: Rename or move locals to avoid shadowing.
6470 (list_processes_1, Fmake_network_process):
6471 (read_process_output_error_handler, exec_sentinel_error_handler):
6472 Rename or move locals.
6473 (Fmake_network_process): Define label "retry_connect" only if needed.
6474 (Fnetwork_interface_info): Fix pointer signedness.
6475 (process_send_signal): Add cast to avoid pointer signedness problem.
6476 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
6477 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
6479 Make tparam.h and terminfo.c consistent.
6480 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
6481 Include tparam.h instead, since it declares them.

6540 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
6541 clobbering (Bug#8298).
6542 * sysdep.c (sys_subshell): Likewise.
6543 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
6545 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.

6719 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6720 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
6721 to use the following functions instead of these macros.
6722 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
6723 EMACS_INT, since callers assume the returned value fits in int.
6724 (upcase1): Likewise, for UPCASE_TABLE.

6737 (RETALLOC_IF): Define only if needed.
6738 (WORDCHAR_P): Likewise. This one is never needed, but is used
6739 only in a comment talking about a compiler bug, so put inside
6740 the #if 0 of that comment.
6741 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
6742 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
6745 * search.c (boyer_moore): Rename locals to avoid shadowing.

6770 gcpro1, gcpro2, etc.
6771 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
6773 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
6774 argument, for consistency with GCPRO2_VAR, etc: it is now the
6775 prefix of the variable, not the variable itself. All uses
6777 * dired.c (directory_files_internal, file_name_completion):
6778 Rename locals to avoid shadowing.
6780 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
6781 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
6782 dired.c's scmp function, had undefined behavior.
6783 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6784 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
6785 * buffer.h: ... to here, because these macros use current_buffer,
6786 and the new implementation with inline functions needs to have
6787 current_buffer in scope now, rather than later when the macros
6789 (downcase, upcase1): New static inline functions.
6790 (DOWNCASE, UPCASE1): Reimplement using these functions.
6791 This avoids undefined behavior in expressions like
6792 DOWNCASE (x) == DOWNCASE (y), which previously suffered
6793 from race conditions in accessing the global variables
6794 case_temp1 and case_temp2.
6795 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
6796 * lisp.h (case_temp1, case_temp2): Remove their decls.
6797 * character.h (ASCII_CHAR_P): Move from here ...
6798 * lisp.h: ... to here, so that the inline functions mentioned
6801 * dired.c (directory_files_internal_unwind): Now static.
6803 * fileio.c (file_name_as_directory, directory_file_name):
6804 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
6806 (file_name_as_directory): Use const pointers when appropriate.
6807 (Fexpand_file_name): Likewise. In particular, newdir might
6808 point at constant storage, so make it a const pointer.
6809 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
6810 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
6812 (Fset_file_times, Finsert_file_contents, auto_save_error):

6822 so that gcc does not warn that these functions aren't declared.
6824 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
6825 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

6830 (lock_file_1): Rename local to avoid shadowing.
6832 * buffer.c (fix_overlays_before): Mark locals as initialized.
6833 (fix_start_end_in_overlays): Likewise. This function should be
6834 simplified by using pointers-to-pointers, but that's a different
6836 (switch_to_buffer_1): Now static.
6837 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
6838 (report_overlay_modification): Rename locals to avoid shadowing.
6840 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
6841 Fix pointer signedness issue.
6842 (sys_subshell): Mark local as volatile if checking for lint,
6843 to suppress a gcc -Wclobbered warning that does not seem to be right.
6844 (MAXPATHLEN): Define only if needed.
6846 * process.c (serial_open, serial_configure): Move decls from here ...
6847 * systty.h: ... to here, so that they can be checked.
6849 * fns.c (get_random, seed_random): Move extern decls from here ...
6850 * lisp.h: ... to here, so that they can be checked.
6852 * sysdep.c (reset_io): Now static.

6886 if GCC considers string literals to be constants.
6888 * lisp.h (fatal_error_signal): Add decl, since it's exported.
