1 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
5 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
7 * minibuf.c (Fread_from_minibuffer): Doc fix.
9 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
12 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
17 value for non-existent files.
19 2011-09-11 Eli Zaretskii <eliz@gnu.org>
21 * fileio.c (Finsert_file_contents): If the file cannot be opened,
22 set its "size" to -1. This will set the modtime_size field of
23 the corresponding buffer to -1, which is what
24 verify-visited-file-modtime expects for files that do not exist.
27 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
29 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
31 * lisp.h: ... from here. push_key_description is no longer
32 defined in keyboard.c, so its declaration should not be in
33 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
34 logically belongs with push_key_description.
36 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
38 * buffer.h: Include <sys/types.h> instead of <time.h>.
39 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
40 Problem reported by Herbert J. Skuhra.
42 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
44 * xml.c (parse_region): Make the parsing work for
45 non-comment-starting XML files again (bug#9144).
47 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
49 * image.c (gif_load): Fix calculation of bottom and right corner.
52 2011-09-10 Eli Zaretskii <eliz@gnu.org>
54 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
55 redisplay in small windows.
57 2011-09-09 Eli Zaretskii <eliz@gnu.org>
59 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
61 2011-09-08 Martin Rudalics <rudalics@gmx.at>
63 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
64 Operate on live windows only.
66 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
68 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
70 2011-09-07 Eli Zaretskii <eliz@gnu.org>
72 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
73 only under bidi iteration.
75 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
77 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
79 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
81 isnan: Fix porting problem to Solaris 10 with bundled gcc.
82 Without this fix, the command to link temacs failed due to an
83 undefined symbol __builtin_isnan. This is because
84 /usr/include/iso/math_c99.h #defines isnan(x) to
85 __builtin_isnan(x), but the bundled gcc, which identifies itself
86 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
88 * floatfns.c (isnan): #undef, and then #define to a clone of
90 (Fisnan): Always define, since it's always available now.
91 (syms_of_floatfns): Always define isnan at the Lisp level.
93 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
95 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
97 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
99 * fileio.c: Fix bugs with large file offsets (Bug#9428).
100 The previous code assumed that file offsets (off_t values) fit in
101 EMACS_INT variables, which is not true on typical 32-bit hosts.
102 The code messed up by falsely reporting buffer overflow in cases
103 such as (insert-file-contents "big" nil 1 2) into an empty buffer
104 when "big" contains more than 2**29 bytes, even though this
105 inserts just one byte and does not overflow the buffer.
106 (Finsert_file_contents): Store file offsets as off_t
107 values, not as EMACS_INT values. Check for overflow when
108 converting between EMACS_INT and off_t. When checking for
109 buffer overflow or for overlap, take the offsets into account.
110 Don't use EMACS_INT for small values where int suffices.
111 When checking for overlap, fix a typo: ZV was used where
112 ZV_BYTE was intended.
113 (Fwrite_region): Don't assume off_t fits into 'long'.
114 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
116 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
118 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
120 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
122 sprintf-related integer and memory overflow issues (Bug#9412).
124 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
125 (esprintf, exprintf, evxprintf): New functions.
126 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
127 (cmd_error): kbd macro iterations count is now EMACS_INT, not int.
128 (modify_event_symbol): Do not assume that the length of
129 name_alist_or_stem is safe to alloca and fits in int.
130 (Fexecute_extended_command): Likewise for function name and binding.
131 (Frecursion_depth): Wrap around reliably on integer overflow.
132 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
133 since some callers pass EMACS_INT values.
134 (Fsingle_key_description): Don't crash if symbol name contains more
135 than MAX_ALLOCA bytes.
136 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
137 (get_minibuffer): Arg is now EMACS_INT, not int.
138 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
139 (esprintf, exprintf, evxprintf): New decls.
140 * window.h (command_loop_level, minibuf_level): Reflect API changes.
142 * dbusbind.c (signature_cat): New function.
143 (xd_signature, Fdbus_register_signal):
144 Do not overrun buffer; instead, report string overflow.
146 * dispnew.c (add_window_display_history): Don't overrun buffer.
147 Truncate instead; this is OK since it's just a log.
149 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
150 even if the time zone offset is outlandishly large.
151 Don't mishandle offset == INT_MIN.
153 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
154 when creating daemon; the previous buffer-overflow check was incorrect.
156 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
157 which has the guts of the old verror function.
159 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
160 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
162 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
163 (font_unparse_xlfd): Don't blindly alloca long strings.
164 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
165 fits in int, when using sprintf. Use single snprintf to count
166 length of string rather than counting it via multiple sprintfs;
167 that's simpler and more reliable.
168 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
169 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
170 sprintf, in case result does not fit in int.
172 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
173 (fontset_from_font): Print it.
175 * frame.c (tty_frame_count): Now printmax_t, not int.
176 (make_terminal_frame, set_term_frame_name): Print it.
177 (x_report_frame_params): In X, window IDs are unsigned long,
178 not signed long, so print them as unsigned.
179 (validate_x_resource_name): Check for implausibly long names,
180 and don't assume name length fits in 'int'.
181 (x_get_resource_string): Don't blindly alloca invocation name;
182 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
185 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
186 (xg_check_special_colors, xg_set_geometry):
187 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
189 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
190 Use esprintf, not sprintf, in case result does not fit in int.
192 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
193 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
194 it as a large positive number.
195 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
196 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
198 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
199 in case result does not fit in int.
201 * print.c (float_to_string): Detect width overflow more reliably.
202 (print_object): Make sprintf buffer a bit bigger, to avoid potential
203 buffer overrun. Don't assume list length fits in 'int'. Treat
204 print length of 0 as 0, not as infinity; to be consistent with other
205 uses of print length in this function. Don't overflow print length
206 index. Don't assume hash table size fits in 'long', or that
207 vectorlike size fits in 'unsigned long'.
209 * process.c (make_process): Use printmax_t, not int, to format
210 process-name gensyms.
212 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
214 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
215 to avoid potential buffer overrun.
217 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
218 if X resource line is longer than 512 bytes.
220 * xfns.c (x_window): Make sprintf buffer a bit bigger
221 to avoid potential buffer overrun.
223 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
225 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
227 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
229 Integer overflow fixes for scrolling, etc.
230 Without these, Emacs silently mishandles large integers sometimes.
231 For example, "C-u 4294967297 M-x recenter" was treated as if
232 it were "C-u 1 M-x recenter" on a typical 64-bit host.
234 * xdisp.c (try_window_id): Check Emacs fixnum range before
237 * window.c (window_scroll_line_based, Frecenter):
238 Check that an Emacs fixnum is in range before assigning it to 'int'.
239 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
240 values converted from Emacs fixnums.
241 (Frecenter): Don't wrap around a line count if it is out of 'int'
242 range; instead, treat it as an extreme value.
243 (Fset_window_configuration, compare_window_configurations):
244 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
246 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
247 that can exceed INT_MAX. Check that EMACS_INT value is in range
248 before assigning it to the (possibly-narrower) index.
249 (match_limit): Don't assume that a fixnum can fit in 'int'.
251 * print.c (print_object): Use ptrdiff_t, not int, for index that can
254 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
255 (Fvertical_motion): Don't wrap around LINES values that don't fit
256 in 'int'. Instead, treat them as extreme values. This is good
257 enough for windows, which can't have more than INT_MAX lines anyway.
259 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
261 * Require libxml/parser.h to avoid compilation warning.
263 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
265 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
266 since this reportedly can destroy thread storage.
268 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
270 * syntax.c (find_defun_start): Update all cache variables if
271 exiting early (Bug#9401).
273 2011-08-30 Eli Zaretskii <eliz@gnu.org>
275 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
277 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
278 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
279 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
281 * term.c (tty_append_glyph): New function.
282 (produce_stretch_glyph): Static function and its prototype deleted.
284 * dispextern.h (produce_stretch_glyph, tty_append_glyph): Add
287 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
289 * image.c (parse_image_spec): Check for nonnegative, not for positive,
290 when checking :margin (Bug#9390).
291 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
292 Renamed from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
293 so that the name doesn't mislead. All uses changed.
295 2011-08-28 Johan Bockgård <bojohan@gnu.org>
297 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
300 2011-08-27 Eli Zaretskii <eliz@gnu.org>
302 * xdisp.c (move_it_to): Don't bail out early when reaching
303 position beyond to_charpos, if we are scanning backwards.
304 (move_it_vertically_backward): When DY == 0, make sure we get to
305 the first character in the line after the newline.
307 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
309 * ccl.c: Improve and simplify overflow checking (Bug#9196).
310 (ccl_driver): Do not generate an out-of-range pointer.
311 (Fccl_execute_on_string): Remove unnecessary check for
312 integer overflow, noted by Stefan Monnier in
313 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
314 Remove a FIXME that didn't need fixing.
315 Simplify the newly-introduced buffer reallocation code.
317 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
319 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
321 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
323 Integer and memory overflow issues (Bug#9196).
325 * doc.c (get_doc_string): Rework so that
326 get_doc_string_buffer_size is the actual buffer size, rather than
327 being 1 less than the actual buffer size; this makes xpalloc more
330 * image.c (x_allocate_bitmap_record, cache_image):
331 * xselect.c (Fx_register_dnd_atom):
332 Simplify previous changes by using xpalloc.
334 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
335 since either will do and ptrdiff_t is convenient with xpalloc.
337 * charset.c (charset_table_size)
338 (struct charset_sort_data.priority): Now ptrdiff_t.
339 (charset_compare): Don't overflow if priorities differ greatly.
340 (Fsort_charsets): Don't assume list length fits in int.
341 Check for size-calculation overflow when allocating sort data.
342 (syms_of_charset): Allocate an initial charset table that is
343 just under 64 KiB, to avoid problems with glibc malloc and mmap.
345 * cmds.c (internal_self_insert): Check for size-calculation overflow.
347 * composite.h (struct composition.glyph_len): Now int, not unsigned.
348 The actual value is always <= INT_MAX, and leaving it unsigned made
349 overflow checking harder.
351 * dispextern.h (struct glyph_matrix.rows_allocated)
352 (struct face_cache.size): Now ptrdiff_t, for convenience in use
353 with xpalloc. The values are still always <= INT_MAX.
355 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
357 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
358 (SAFE_NALLOCA): New macro.
360 * region-cache.c (struct boundary.pos, find_cache_boundary)
361 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
362 (set_cache_region, invalidate_region_cache)
363 (revalidate_region_cache, know_region_cache, region_cache_forward)
364 (region_cache_backward, pp_cache):
365 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
366 so that ptrdiff_t * can be passed to xpalloc.
367 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
368 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
369 (pp_cache): Don't assume cache_len fits in int.
370 * region-cache.h: Adjust extern decls to match.
372 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
373 EMACS_INT, since either will do, for xpalloc.
375 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
376 (xnmalloc, xnrealloc, xpalloc): New functions.
378 * bidi.c (bidi_shelve_header_size): New constant.
379 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
380 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
382 * bidi.c (bidi_cache_shrink):
383 * buffer.c (overlays_at, overlays_in, record_overlay_string)
385 Don't update size of array until after memory allocation succeeds,
386 because xmalloc/xrealloc may not return.
387 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
388 now that we have proper integer overflow checking.
389 (record_overlay_string, overlay_strings): Catch overflows when
390 calculating size of overlay_str_buf.
392 * callproc.c (Fcall_process): Check for size overflow when
393 calculating size of args2.
394 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
395 Normally we prefer signed values, but sticking with ptrdiff_t would
396 require adding more-complicated checks.
398 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
399 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
400 Redo buffer-overflow calculations to avoid integer overflow.
401 Add a FIXME comment where memory seems to be over-allocated.
403 * character.c (Fstring): Check for size-calculation overflow.
405 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
406 unnecessary integer overflow. Check for size overflow.
407 (encode_coding_object): Don't update size until xmalloc succeeds.
409 * composite.c (get_composition_id): Check for overflow in glyph
412 Integer and memory overflow fixes for display code.
413 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
414 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
415 (scrolling_window): Check for overflow in size calculations.
416 (line_draw_cost, realloc_glyph_pool, add_row_entry):
417 Don't assume glyph table len fits in int.
418 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
419 (row_table_size): Now ptrdiff_t, not int.
420 (scrolling_window): Avoid overflow in size calculations.
421 Don't update size until allocation succeeds.
422 * fns.c (concat): Check for overflow in size calculations.
423 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
424 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
425 (NEXT_ALMOST_PRIME_LIMIT): New constant.
427 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
428 (get_doc_string): Check for size calculation overflow.
429 Don't update size until allocation succeeds.
430 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
431 EMACS_INT, where ptrdiff_t will do.
432 (Fsubstitute_command_keys): Check for string overflow.
434 * editfns.c (set_time_zone_rule): Don't assume environment length
436 (message_length): Now ptrdiff_t, not int.
437 (Fmessage_box): Don't update size until allocation succeeds.
438 Don't assume message length fits in int.
439 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
441 * emacs.c (main): Do not reallocate argv, since there is a null at
442 the end that can be overwritten, and this way there's no need to
443 worry about size-calculation overflow.
444 (sort_args): Check for size-calculation overflow.
446 * eval.c (init_eval_once, grow_specpdl): Don't update size until
448 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
450 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
451 (x_set_scroll_bar_width, x_figure_window_size):
452 Check for integer overflow.
453 (x_set_alpha): Do not assume XINT fits in int.
455 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
456 This is for the members text_lines, text_cols, total_lines, total_cols,
457 where the system imposes an 'int' limit.
459 * fringe.c (Fdefine_fringe_bitmap):
460 Don't update size until alloc works.
462 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
463 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
465 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
466 Check for size-calculation overflow.
467 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
468 do, as we prefer signed integers.
469 (id_to_widget.max_size, id_to_widget.used)
470 (xg_store_widget_in_map, xg_remove_widget_from_map)
471 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
472 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
473 Use and return ptrdiff_t, not int.
474 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
475 * gtkutil.h: Change prototypes to match the above.
477 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
478 are duplicate now that they've been promoted to lisp.h.
479 (x_allocate_bitmap_record, x_alloc_image_color)
480 (make_image_cache, cache_image, xpm_load):
481 Don't update size until alloc is done.
482 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
484 Check for size calculation overflow.
485 (ct_colors_allocated_max): New constant.
486 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
489 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
490 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
491 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
492 Use ptrdiff_t, not int, to count maps.
493 (read_char_minibuf_menu_prompt): Check for overflow in size
494 calculations. Don't update size until allocation succeeds. Redo
495 calculations to avoid overflow.

522 (Fset_match_data): Don't assume list lengths fit in 'int'.
524 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
525 for command line length. Do not attempt to address one before the
526 beginning of an array, as that's not portable.
528 * term.c (max_frame_lines): Remove; unused.

531 (encode_terminal_code, calculate_costs): Check for size
532 calculation overflow.

558 memory exhaustion (the usual treatment), rather than aborting.
560 * xfns.c (x_encode_text, x_set_name_internal)
561 (Fx_change_window_property): Use ptrdiff_t, not int, to count
562 sizes, since they can exceed INT_MAX in size. Check for size
563 calculation overflow.
565 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
566 (xg_select): Check for size calculation overflow.
567 Don't update size until alloc done.
569 * xrdb.c (get_environ_db): Don't assume path length fits in int,
570 as sprintf is limited to int lengths.
572 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
573 (X_LONG_MIN): New macros.
574 Use them to make the following changes clearer.
575 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
576 This change doesn't affect the value now, but it may help remind
577 future maintainers not to raise the value too much later.
578 (SELECTION_QUANTUM): Remove, replacing with ...
579 (selection_quantum): ... new function, which avoids overflow.
581 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
582 assumption that selection length fits in 'int'.
583 (x_reply_selection_request, x_handle_selection_request)
584 (x_get_window_property, receive_incremental_selection)
585 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)

600 (x_get_window_property): Plug memory leak on memory exhaustion.
601 Don't double-block input; malloc is safe here. Don't assume 2**34
602 - 4 fits in unsigned long. Add an xassert to check
603 XGetWindowProperty overflow. Be more careful about overflow
604 calculations, and distinguish size from memory overflow better.
605 (receive_incremental_selection): When tracing, don't assume
606 unsigned int is less than INT_MAX.
607 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
608 harmful) conversions of unsigned short to int.
609 (lisp_data_to_selection_data): Don't assume that integers
610 in the range -65535 through -1 fit in an X unsigned short.
611 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
612 result parameters unless successful. Rely on cons_to_unsigned
613 to report problems with elements; the old code wasn't right anyway.
614 (x_check_property_data): Check for int overflow; we cannot use
615 a wider type due to X limits.
616 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

647 * image.c (xpm_get_color_table_h):
648 * lisp.h (hash_lookup, hash_put):
649 * minibuf.c (Ftest_completion):
650 Use ptrdiff_t for hash table indexes, not int (which is too
651 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
652 32-bit --with-wide-int hosts).
654 * charset.c (Fdefine_charset_internal): Check for integer overflow.
655 Add a FIXME comment about memory leaks.

660 * character.h (CHAR_WIDTH):
661 * indent.c (MULTIBYTE_BYTES_WIDTH):
662 Use sanitize_char_width to avoid undefined and/or bad behavior
663 with outlandish widths.

665 now that we have two such functions. All uses changed.
666 (sanitize_char_width): New inline function.

681 (read_hex, load_charset_map_from_file): Check for integer overflow.
683 * xterm.c: don't go over XClientMessageEvent limit
684 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
685 (x_send_scroll_bar_event): Likewise. Check that the size does not
686 exceed limits imposed by XClientMessageEvent, as well as the usual
687 ptrdiff_t and size_t limits.
689 * keyboard.c: Overflow, signedness and related fixes.
690 (make_lispy_movement): Use same integer type in forward decl
691 that is used in the definition.
692 (read_key_sequence, keyremap_step):
693 Change bufsize argument back to int, undoing my 2011-03-30 change.
694 We prefer signed types, and int is wide enough here.
695 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
696 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
697 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
698 length, not size_t. Use ptrdiff_t for index, not int.
699 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
700 possibility of integer overflow.

723 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
724 (lookup_image): Remove unnecessary tests.
725 (xbm_image_p): Locals are now of int, not EMACS_INT,
726 since parse_image_check makes sure they fit into int.
727 (png_load, gif_load, svg_load_image):
728 Prefer int to unsigned where either will do.
729 (tiff_handler): New function, combining the cores of the
730 old tiff_error_handler and tiff_warning_handler. This
731 function is rewritten to use vsnprintf and thereby avoid
732 stack buffer overflows. It uses only the features of vsnprintf
733 that are common to both POSIX and native Microsoft.
734 (tiff_error_handler, tiff_warning_handler): Use it.
735 (tiff_load, gif_load, imagemagick_load_image):
736 Don't assume :index value fits in 'int'.
737 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

755 handle_single_display_spec, not just 1 or zero.
756 (handle_single_display_spec): If the display spec is of the form
757 `(space ...)', and specifies display in the text area, return 2
759 (try_cursor_movement): Check for the need to scroll more
760 accurately, and prefer exact match for point under bidi. Don't
761 advance `row' beyond the last row of the window.
763 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
764 into disp_prop; all users changed.
766 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
767 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
768 for the text covered by the display property.
770 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
772 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

779 buffers, return left-to-right.
780 (set_cursor_from_row): Consider candidate row a win if its glyph
781 represents a newline and point is on that newline. Fixes cursor
782 positioning on the newline at EOL of R2L text within L2R
783 paragraph, and vice versa.
784 (try_cursor_movement): Check continued rows, in addition to
785 continuation rows. Fixes unwarranted scroll when point enters a
786 continued line of R2L text within an L2R paragraph, or vice versa.
787 (cursor_row_p): Consider the case of point being equal to
788 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
789 from the end of a short line to the beginning of a continued line
790 of R2L text within L2R paragraph.
791 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

812 2011-08-23 Eli Zaretskii <eliz@gnu.org>
814 * xdisp.c (redisplay_window): When computing centering_position,
815 account for the height of the header line. (Bug#8874)
817 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
818 instead of CHAR_TO_BYTE. Fixes a crash when a completion
819 candidate is selected by the mouse, and that candidate has a
820 composed character under the mouse.
822 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
823 coordinates reported by pos-visible-in-window-p for a composed

838 * image.c (gif_load): Don't assume that each subimage has the same
839 dimensions as the base image. Handle disposal method that is
840 "undefined" by the gif spec (Bug#9335).
842 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
844 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

849 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
850 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
851 from an Org mode buffer to a Speedbar frame.
853 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
854 a composition, take its buffer position from IT->cmp_it.charpos.
855 Fixes cursor positioning at the beginning of a line that begins
856 with a composed character.
858 2011-08-18 Eli Zaretskii <eliz@gnu.org>
860 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
861 character bidirectional type, use STRONG_L instead. Fixes crashes
862 in a buffer produced by `describe-categories'.
864 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
865 members before the level stack, so they would be saved and
866 restored when copying iterator state. Fixes incorrect reordering
867 around TABs covered by display properties.
869 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

990 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
991 (Fnetwork_interface_list): Allocate in increments of bytes instead
992 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
993 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
995 (struct ifflag_def): notrailers is smart on OSX.
996 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
997 Get hardware address with getifaddrs if available.
999 2011-08-12 Eli Zaretskii <eliz@gnu.org>
1001 * xdisp.c (iterate_out_of_display_property): xassert that
1002 IT->position is set to within IT->object's boundaries. Break from
1003 the loop as soon as EOB is reached; avoids infloops in redisplay
1004 when IT->position is set up wrongly due to some bug.
1005 Set IT->current to match the bidi iterator unconditionally.
1006 (push_display_prop): Allow GET_FROM_STRING as IT->method on
1007 entry. Force push_it to save on the stack the current
1008 buffer/string position, to be restored by pop_it. Fix flags in
1009 the iterator structure wrt the object coming from a display
1010 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
1011 properties. (Bug#9284)
1013 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
1015 * fontset.c (fontset_get_font_group): Add proper type checks.
1018 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1020 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
1021 and LC_VERSION_MIN_MACOSX.
1022 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
1023 (dump_it) [LC_FUNCTION_STARTS]: Use it.
1025 2011-08-08 Eli Zaretskii <eliz@gnu.org>
1027 * xdisp.c (forward_to_next_line_start): Allow to use the
1028 no-display-properties-and-no-overlays under bidi display.
1029 Set disp_pos in the bidi iterator to avoid searches for display
1030 properties and overlays.
1032 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
1034 * editfns.c (Fset_time_zone_rule): Document relationship with the
1037 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
1038 the font entity extracted from the cache (Bug#8109).
1040 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
1042 * composite.c (autocmp_chars): Don't reset point. That is done by
1043 restore_point_unwind (Bug#5984).
1045 2011-08-07 Juri Linkov <juri@jurta.org>
1047 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
1048 to show the arg `TIME' instead of `TIMEVAL'.
1050 2011-08-06 Eli Zaretskii <eliz@gnu.org>
1052 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
1053 display property strides EOL and includes a newline, as in
1054 longlines-mode. (Bug#9254)
1055 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
1056 word-wrap under bidirectional display. (Bug#9224)
1058 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
1059 is non-zero, even if the data buffer is NULL. Fixes a crash in
1060 vertical-motion with longlines-mode. (Bug#9254)
1062 2011-08-05 Eli Zaretskii <eliz@gnu.org>
1064 * bidi.c <bidi_cache_total_alloc>: Now static.
1065 (bidi_initialize): Initialize bidi_cache_total_alloc.
1067 * xdisp.c (display_line): Release buffer allocated for shelved bidi
1070 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
1071 amount allocated this far in `bidi_cache_total_alloc'.
1072 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
1073 non-zero, only free the data buffer without restoring the cache
1074 contents. All callers changed.
1076 * dispextern.h (bidi_unshelve_cache): Update prototype.
1078 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
1079 (move_it_in_display_line, move_it_to)
1080 (move_it_vertically_backward, move_it_by_lines): Replace the call
1081 to xfree to an equivalent call to bidi_unshelve_cache.
1082 (move_it_in_display_line_to): Fix logic of returning
1083 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
1085 2011-08-05 Eli Zaretskii <eliz@gnu.org>
1087 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
1088 came from a string character with a `cursor' property. (Bug#9229)
1090 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
1092 * Makefile.in (LIB_PTHREAD): New variable.
1093 (LIBES): Add LIB_PTHREAD (Bug#9216).
1095 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
1096 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
1098 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
1100 * regex.c (re_iswctype): Remove some redundant boolean
1103 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
1105 * xterm.c (x_find_topmost_parent): New function.
1106 (x_set_frame_alpha): Find topmost parent window with
1107 x_find_topmost_parent and set the property there also (bug#9181).
1108 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
1110 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
1112 * callproc.c (Fcall_process): Avoid vfork clobbering
1113 the local vars buffer, coding_systems, current_dir.
1115 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
1117 * keymap.c (Fmake_composed_keymap): Move to subr.el.
1119 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
1121 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
1122 so that it is not optimized away.
1124 * xdisp.c (compute_display_string_pos): Remove unused local.
1126 2011-08-02 Eli Zaretskii <eliz@gnu.org>
1128 Fix slow cursor motion and scrolling in large buffers with
1129 selective display, like Org Mode buffers. (Bug#9218)
1131 * dispextern.h (struct bidi_it): New member disp_prop_p.
1133 * xdisp.c: Remove one-slot cache of display string positions.
1134 (compute_display_string_pos): Accept an additional argument
1135 DISP_PROP_P; callers changed. Scan at most 5K characters forward
1136 for a display string or property. If found, set DISP_PROP_P
1139 * bidi.c (bidi_fetch_char): Accept an additional argument
1140 DISP_PROP_P, and pass it to compute_display_string_pos.
1141 Only handle text covered by a display string if DISP_PROP_P is returned
1142 non-zero. All callers of bidi_fetch_char changed.
1144 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
1146 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
1148 2010-12-03 Don March <don@ohspite.net>
1150 * keymap.c (Fdefine_key): Fix non-prefix key error message when
1151 last character M-[char] is translated to ESC [char] (bug#7541).
1153 2011-08-02 Kenichi Handa <handa@m17n.org>
1155 * lisp.h (uniprop_table): Extern it.
1157 * chartab.c (uniprop_table): Make it non-static.
1159 2011-08-01 Eli Zaretskii <eliz@gnu.org>
1161 * xdisp.c (forward_to_next_line_start): Accept additional argument
1162 BIDI_IT_PREV, and store into it the state of the bidi iterator had
1164 (reseat_at_next_visible_line_start): Use the bidi iterator state
1165 returned by forward_to_next_line_start to restore the state of
1166 it->bidi_it after backing up to previous newline. (Bug#9212)
1168 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
1170 * regex.c (re_comp): Protoize.
1171 (re_exec): Fix return type.
1172 (regexec): Fix type of `ret'. (Bug#9203)
1174 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
1176 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
1177 This is needed if max-image-size is a floating-point number.
1179 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
1181 * print.c (print_object): Print empty symbol as ##.
1183 * lread.c (read1): Read ## as empty symbol.
1185 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
1187 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
1188 setting frame foreground color (Bug#9175).
1189 (x_set_background_color): Likewise.
1191 * nsmenu.m (-setText): Size tooltip dimensions precisely to
1192 contents (Bug#9176).
1193 (EmacsTooltip -init): Remove bezels and add shadows to
1196 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
1197 or scroll bar (Bug#8470).
1199 * nsfont.m (nsfont_open): Remove assignment to voffset and
1200 unnecessary vars hshink, expand, hd, full_height, min_height.
1201 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
1203 * nsterm.h (nsfont_info): Remove voffset field.
1205 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
1207 Implement strike-through and overline on NextStep (Bug#8863).
1209 * nsfont.m (nsfont_open): Use underline position provided by font,
1210 instead of hard-coded value of 2.
1211 (nsfont_draw): Call ns_draw_text_decoration instead.
1213 * nsterm.h: Add declaration for ns_draw_text_decoration.
1215 * nsterm.m (ns_draw_text_decoration): New function for drawing
1216 underline, overline, and strike-through.
1217 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
1218 ns_draw_text_decoration. Change treatment of cursor drawing to
1219 accomodate underlining, etc.
1221 2011-07-28 Eli Zaretskii <eliz@gnu.org>
1223 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
1226 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
1228 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
1229 Without this fix, if a signal arrives just after memory fills up,
1230 'malloc' might be invoked reentrantly.
1232 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
1233 In other words, assume that every image size is allowed, on non-X
1234 hosts. This assumption is probably wrong, but it lets Emacs compile.
1236 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
1238 * regex.c (re_iswctype): Convert return values to boolean.
1240 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
1242 * xdisp.c (compute_display_string_pos): Don't use cached display
1243 string position if the buffer had its restriction changed.
1246 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
1248 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
1250 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
1252 Integer signedness and overflow and related fixes. (Bug#9079)
1254 * bidi.c: Integer size and overflow fixes.
1255 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
1256 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
1257 (bidi_cache_find_level_change, bidi_cache_ensure_space)
1258 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
1259 (bidi_find_other_level_edge):
1260 Use ptrdiff_t instead of EMACS_INT where either will do.
1261 This works better on 32-bit hosts configured --with-wide-int.
1262 (bidi_cache_ensure_space): Check for size-calculation overflow.
1263 Use % rather than repeated addition, for better worst-case speed.
1264 Don't set bidi_cache_size until after xrealloc returns, because it
1266 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
1267 (bidi_cache_ensure_space): Also check that the bidi cache size
1268 does not exceed that of the largest Lisp string or buffer. See Eli
1269 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
1271 * alloc.c (__malloc_size_t): Remove.
1272 All uses replaced by size_t. See Andreas Schwab's note
1273 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
1275 * image.c: Improve checking for integer overflow.
1276 (check_image_size): Assume that f is nonnull, since
1277 it is always nonnull in practice. This is one less thing to
1278 worry about when checking for integer overflow later.
1279 (x_check_image_size): New function, which checks for integer
1280 overflow issues inside X.
1281 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
1282 This removes the need for a memory_full check.
1283 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
1284 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
1285 (xbm_read_bitmap_data): Change locals back to 'int', since
1286 their values must fit in 'int'.
1287 (xpm_load_image, png_load, tiff_load):
1288 Invoke x_create_x_image_and_pixmap earlier,
1289 to avoid much needless work if the image is too large.
1290 (tiff_load): Treat overly large images as if
1291 x_create_x_image_and_pixmap failed, not as malloc failures.
1292 (gs_load): Use x_check_image_size.
1294 * gtkutil.c: Omit integer casts.
1295 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
1296 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
1298 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
1300 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
1301 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
1302 would wrongly return t on a 64-bit host.
1304 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
1305 The plain *_OVERFLOW macros run afoul of GCC bug 49705
1306 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
1307 and therefore cause GCC to emit a bogus diagnostic in some cases.
1309 * image.c: Integer signedness and overflow and related fixes.
1310 This is not an exhaustive set of fixes, but it's time to
1311 record what I've got.
1312 (lookup_pixel_color, check_image_size): Remove redundant decls.
1313 (check_image_size): Don't assume that arbitrary EMACS_INT values
1314 fit in 'int', or that arbitrary 'double' values fit in 'int'.
1315 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
1316 (tiff_load, imagemagick_load_image):
1317 Check for overflow in size calculations.
1318 (x_create_x_image_and_pixmap): Remove unnecessary test for
1319 xmalloc returning NULL; that can't happen.
1320 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
1321 (xpm_color_bucket): Use better integer hashing function.
1322 (xpm_cache_color): Don't possibly over-allocate memory.
1323 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
1324 (gif_memory_source):
1325 Use ptrdiff_t, not int or size_t, to record sizes.
1326 (png_load): Don't assume values greater than 2**31 fit in 'int'.
1327 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
1328 either works, as we prefer signed integers.
1329 (tiff_read_from_memory, tiff_write_from_memory):
1330 Return tsize_t, not size_t, since that's what the TIFF API wants.
1331 (tiff_read_from_memory): Don't fail simply because the read would
1332 go past EOF; instead, return a short read.
1333 (tiff_load): Omit no-longer-needed casts.
1334 (Fimagemagick_types): Don't assume size fits into 'int'.
1336 Improve hashing quality when configured --with-wide-int.
1337 * fns.c (hash_string): New function, taken from sxhash_string.
1338 Do not discard information about ASCII character case; this
1339 discarding is no longer needed.
1340 (sxhash-string): Use it. Change sig to match it. Caller changed.
1341 * lisp.h: Declare it.
1342 * lread.c (hash_string): Remove, since we now use fns.c's version.
1343 The fns.c version returns a wider integer if --with-wide-int is
1344 specified, so this should help the quality of the hashing a bit.
1346 * emacs.c: Integer overflow minor fix.
1347 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
1348 Define only if GNU_LINUX.
1349 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
1351 * dispnew.c: Integer signedness and overflow fixes.
1352 Remove unnecessary forward decls, that were a maintenance hassle.
1353 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
1355 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
1356 (scrolling_window): Use ptrdiff_t, not int, for byte count.
1357 (prepare_desired_row, line_draw_cost):
1358 Use int, not unsigned, where either works.
1359 (save_current_matrix, restore_current_matrix):
1360 Use ptrdiff_t, not size_t, where either works.
1361 (init_display): Check for overflow more accurately, and without
1362 relying on undefined behavior.
1364 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
1365 Remove, replacing with the new symbols in lisp.h. All uses changed.
1366 * fileio.c (make_temp_name):
1367 * filelock.c (lock_file_1, lock_file):
1368 * xdisp.c (message_dolog):
1369 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
1370 Use pMd etc. instead.
1371 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
1372 replacing the pWIDE etc. symbols removed from editfns.c.
1374 * keyboard.h (num_input_events): Now uintmax_t.
1375 This is (very slightly) less likely to mess up due to wraparound.
1378 * buffer.c: Integer signedness fixes.
1379 (alloc_buffer_text, enlarge_buffer_text):
1380 Use ptrdiff_t rather than size_t when either will do, as we prefer
1383 * alloc.c: Integer signedness and overflow fixes.
1384 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
1385 (__malloc_size_t): Default to size_t, not to int.
1386 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
1387 (Fgarbage_collect, mark_object_loop_halt, mark_object):
1388 Prefer ptrdiff_t to size_t when either would do, as we prefer
1390 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
1391 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
1392 Now const. Initialize with values that are in range even if char
1394 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
1395 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
1396 These functions do the right thing with sizes > 2**32.
1397 (check_depth): Now ptrdiff_t, not int.
1398 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
1399 Adjust to new way of storing sizes. Check for size overflow bugs
1401 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
1402 slightly wrong anyway, as it missed one instance of
1403 XMALLOC_OVERRUN_CHECK_OVERHEAD.
1404 (refill_memory_reserve): Omit needless cast to size_t.
1405 (mark_object_loop_halt): Mark as externally visible.
1407 * xselect.c: Integer signedness and overflow fixes.
1408 (Fx_register_dnd_atom, x_handle_dnd_message):
1409 Use ptrdiff_t, not size_t, since we prefer signed.
1410 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
1411 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
1412 x_dnd_atoms_size and x_dnd_atoms_length.
1414 * doprnt.c: Prefer signed to unsigned when either works.
1416 * doprnt.c (doprnt):
1418 * xdisp.c (vmessage):
1419 Use ptrdiff_t, not size_t, when using or implementing doprnt,
1420 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
1421 prefer signed arithmetic to avoid comparison confusion.
1422 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
1423 but is a bit tricky.
1425 Assume freestanding C89 headers, string.h, stdlib.h.
1426 * data.c, doprnt.c, floatfns.c, print.c:
1427 Include float.h unconditionally.
1428 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
1429 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
1430 * regex.c: Likewise for stddef.h, string.h.
1431 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
1432 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
1433 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
1434 (STDC_HEADERS): Remove obsolete defines.
1435 * sysdep.c: Include limits.h unconditionally.
1437 Assume support for memcmp, memcpy, memmove, memset.
1438 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
1439 * regex.c (memcmp, memcpy):
1440 Remove; we assume C89 now.
1442 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
1443 (__malloc_safe_bcopy): Remove; no longer needed.
1445 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
1446 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
1447 well either way, and we prefer signed to unsigned.

1451 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
1452 closes the connection while we're reading (bug#9182).
1454 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
1456 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
1457 are specified (Bug#9168).
1459 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
1461 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
1462 Found by GCC static checking and --with-wide-int on a 32-bit host.
1464 2011-07-25 Eli Zaretskii <eliz@gnu.org>
1466 * xdisp.c (compute_display_string_pos): Fix logic of caching
1467 previous display string position. Initialize cached_prev_pos to
1468 -1. Fixes slow-down at the beginning of a buffer.
1470 2011-07-24 Eli Zaretskii <eliz@gnu.org>
1472 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
1473 for attrs[LFACE_FONTSET_INDEX].
1475 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
1477 * xml.c (parse_region): Remove unused local
1478 that was recently introduced.
1480 2011-07-23 Eli Zaretskii <eliz@gnu.org>
1482 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
1483 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
1485 * xdisp.c (move_it_in_display_line_to): Record the best matching
1486 position for TO_CHARPOS while scanning the line, and restore it on
1487 exit if none of the characters scanned was an exact match.
1488 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
1489 when exact match is impossible due to invisible text, and the
1490 lines are truncated.
1492 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
1494 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask

1499 Fix a significant slow-down of cursor motion with C-n, C-p,
1500 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
1501 auto-repeat under bidi redisplay in fontified buffers.
1502 * xdisp.c (compute_stop_pos_backwards): New function.
1503 (next_element_from_buffer): Call compute_stop_pos_backwards to
1504 find a suitable prev_stop when we find ourselves before
1506 (reseat): Don't look for prev_stop, as that could mean a very long
1508 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
1509 <cached_disp_overlay_modiff>: Cache for last found display string
1511 (compute_display_string_pos): Return the cached position if asked
1512 about the same buffer in the same area of character positions, and
1513 the buffer wasn't changed since the time the display string
1514 position was cached.
1516 2011-07-22 Eli Zaretskii <eliz@gnu.org>
1518 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
1519 is an integer, which is important for empty lines. (Bug#9149)
1521 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
1523 * frame.c (Fmodify_frame_parameters): In tty case, update the
1524 default face if necessary (Bug#4238).
1526 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
1528 * editfns.c (Fstring_to_char): No need to explain what a character
1529 is in the docstring (Bug#6576).
1531 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
1533 * xml.c (parse_region): Make sure we always return a tree.
1535 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
1537 * xml.c (parse_region): If a document contains only comments,
1540 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
1542 * xml.c (make_dom): Return comments, too.
1544 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
1547 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
1548 and the surrounding thread.
1549 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
1550 rather than fgets, and retry after EINTR. Otherwise, 'emacs
1551 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
1553 * s/openbsd.h (BROKEN_SIGIO): Define.
1554 * unexelf.c (unexec) [__OpenBSD__]:
1555 Don't update the .mdebug section of the Alpha COFF symbol table.
1557 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
1559 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
1562 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>

1565 This fixes some race conditions on the permissions of any newly
1568 * alloc.c (valid_pointer_p): Use pipe, not open.
1569 This fixes some permissions issues when debugging.
1571 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
1572 If fchown fails to set both uid and gid, try to set just gid,
1573 as that is sometimes allowed. Adjust the file's mode to eliminate
1574 setuid or setgid bits that are inappropriate if fchown fails.
1576 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
1578 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
1579 to compare Lisp_Objects.

1590 symbol character follows.
1592 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
1594 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
1595 This works around a problem with the previous change to Fcopy_file.
1596 Recent glibc declares fchown with __attribute__((warn_unused_result)),
1597 and without this change, GCC might complain about discarding
1598 fchown's return value.
1600 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
1602 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
1604 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
1606 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
1608 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
1610 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
1611 it's used from the C level.
1613 * process.c: Use the same condition for POLL_FOR_INPUT in both
1614 keyboard.c and process.c (bug#1858).
1616 2011-07-09 Lawrence Mitchell <wence@gmx.li>

1623 * doc.c (Fsubstitute_command_keys): Revert last change.
1625 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
1627 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
1628 quotes the next character, and doesn't affect other longer
1629 sequences (bug#8935).
1631 * lread.c (syms_of_lread): Clarify that is isn't only
1632 `eval-buffer' and `eval-defun' that's affected by
1633 `lexical-binding' (bug#8460).
1635 2011-07-15 Eli Zaretskii <eliz@gnu.org>
1637 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
1638 bidi redisplay when a line includes both an image and is
1641 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
1643 Fix minor problems found by static checking.
1644 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
1645 (elsz): Now a signed constant, not a size_t var. We prefer signed
1646 types to unsigned, to avoid integer comparison confusion. Without
1647 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
1648 "cannot optimize loop, the loop counter may overflow", a symptom
1650 * indent.c (Fvertical_motion): Mark locals as initialized.
1651 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
1653 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
1655 * search.c (Fre_search_backward): Mention `case-fold-search' in
1656 all the re_search_* functions (bug#8138).

1676 buffer position was specified. Initialize paragraph_embedding to
1678 (reseat_to_string): Initialize the bidi iterator.
1679 (display_string): If we need to ignore text properties of
1680 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The

1685 (compute_display_string_end): Support display properties on Lisp
1687 (init_iterator, reseat_1, reseat_to_string): Initialize the
1688 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS

1691 Fix calculation of the object to scan. Fixes an error when using
1693 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
1694 base_level_stop; instead, set base_level_stop to BEGV.
1695 Fixes crashes in vertical-motion.
1696 (next_element_from_buffer): Improve commentary for when
1697 the iterator is before prev_stop.
1698 (init_iterator): Initialize bidi_p from the default value of
1699 bidi-display-reordering, not from buffer-local value. Use the
1700 buffer-local value only if initializing for buffer iteration.
1701 (handle_invisible_prop): Support invisible properties on strings
1702 that are being bidi-reordered.
1703 (set_iterator_to_next): Support bidi reordering of C strings and

1721 parts of next_element_from_buffer, next_element_from_string, and
1722 next_element_from_c_string.
1723 (tool_bar_lines_needed, redisplay_tool_bar)
1724 (display_menu_bar): Force left-to-right direction. Add a FIXME

1739 pushed the iterator stack, restore the internal state of the bidi
1740 iterator by calling bidi_pop_it same number of times.
1741 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
1742 and we are bidi-iterating, don't decrement the iterator position;
1743 instead, set the first_elt flag in the bidi iterator, to produce
1745 (reseat_1): Remove redundant setting of string_from_display_prop_p.
1746 (push_display_prop): xassert that we are iterating a buffer.

1753 (compute_display_string_end): Fix handling the case of C string.
1754 (push_it, pop_it): Save and restore from_disp_prop_p.

1908 The old code sometimes used this field without initializing it.
1910 * alloc.c (gc_sweep): Don't read past end of array.
1911 In theory, the old code could also have corrupted Emacs internals,
1912 though it'd be very unlikely.

2171 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
2172 (clone_per_buffer_values): Don't assume that

2213 Random fixes. E.g., (random) never returned negative values.
2214 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
2215 subseconds part to the entropy, as that's a bit more random.
2216 Prefer signed to unsigned, since the signedness doesn't matter and
2217 in general we prefer signed. When given a limit, use a
2218 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
2219 latter isn't right if USE_2_TAGS_FOR_INTS.
2220 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
2221 not 0..VALMASK. Don't discard "excess" bits that random () returns.

2233 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
2234 This is more efficient than Ffile_directory_p and avoids a minor race.
2236 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
2238 * buffer.c (Foverlay_put): Say what the return value is
2241 * fileio.c (barf_or_query_if_file_exists): Check first if the file
2242 is a directory before asking whether to use the file name
2244 (barf_or_query_if_file_exists): Make the "File is a directory"
2245 error be more correct.
2247 * fns.c (Frequire): Remove the mention of the .gz files, since
2248 that's installation-specific, but keep the mention of
2249 `get-load-suffixes'.
2251 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
2253 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

2264 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
2265 Also (re)move comments that are misplaced or no longer relevant.
2267 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
2269 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

2298 (Frequire): Mention get-load-suffixes.
2300 2011-07-02 Martin Rudalics <rudalics@gmx.at>
2302 * window.h (window): Remove clone_number slot.

2328 (syms_of_keymap): Defsubr make-composed-keymap.
2329 * keyboard.c (menu_bar_items): Use map_keymap_canonical.
2330 (parse_menu_item): Trivial simplification.
2332 2011-07-01 Glenn Morris <rgm@gnu.org>
2334 * Makefile.in (SETTINGS_LIBS): Fix typo.
2336 2011-07-01 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny patch)

2361 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
2364 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
2366 * eval.c (struct backtrace): Simplify and port the data structure.
2367 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
2368 signed bit field, as this assumption is not portable and it makes
2369 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
2370 "char debug_on_exit : 1" as this is not portable either; instead,

2540 * print.c (printchar, strout): Check for string overflow.
2541 (PRINTPREPARE, printchar, strout):
2542 Don't set size unless allocation succeeds.
2544 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
2545 for sizes. Check for string overflow more accurately.

2558 * lread.c: Integer overflow fixes.
2559 (read_integer): Radix is now EMACS_INT, not int,
2560 to improve quality of diagnostics for out-of-range radices.
2561 Calculate buffer size correctly for out-of-range radices.
2562 (read1): Check for integer overflow in radices, and in
2563 read-circle numbers.
2564 (read_escape): Avoid int overflow.
2565 (Fload, openp, read_buffer_size, read1)
2566 (substitute_object_recurse, read_vector, read_list, map_obarray):

2580 (read_escape): Check for hex character overflow.
2582 2011-06-22 Leo Liu <sdl.web@gmail.com>
2584 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
2585 Move to minibuffer.el.
2587 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
2589 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
2590 The following patches are for when GLYPH_DEBUG && !XASSERT.
2591 * dispextern.h (trace_redisplay_p, dump_glyph_string):
2592 * dispnew.c (flush_stdout):
2593 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
2594 Mark as externally visible.
2595 * dispnew.c (check_window_matrix_pointers): Now static.
2596 * dispnew.c (window_to_frame_vpos):
2597 * xfns.c (unwind_create_frame):
2598 * xterm.c (x_check_font): Remove unused local.
2599 * scroll.c (CHECK_BOUNDS):
2600 * xfaces.c (cache_fache): Rename local to avoid shadowing.
2601 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
2602 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
2603 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
2604 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
2606 (debug_method_add): Use va_list and vsprintf rather than relying
2607 on undefined behavior with wrong number of arguments.
2608 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
2609 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
2610 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
2611 since we're not interested in debugging glyphs with old libraries.
2612 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
2613 GCC 4.6.0's static checking.
2615 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
2617 Integer overflow and signedness fixes (Bug#8873).

2627 (x_create_bitmap_from_xpm_data):
2628 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
2629 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
2631 * xfaces.c (load_pixmap):
2632 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):

2634 (.bitmaps_last, struct x_output.icon_bitmap):
2635 Use ptrdiff_t, not int, for bitmap indexes.
2636 (x_allocate_bitmap_record): Check for size overflow.
2637 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
2639 Use ptrdiff_t, not int, for overlay counts.
2640 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
2641 * editfns.c (overlays_around, get_pos_property):

2644 * xfaces.c (face_at_buffer_position):
2645 * buffer.c (OVERLAY_COUNT_MAX): New macro.
2646 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
2647 (Fnext_overlay_change, Fprevious_overlay_change)
2648 (mouse_face_overlay_overlaps, Foverlays_in):
2649 Use ptrdiff_t, not int, for sizes.
2650 (overlays_at, overlays_in): Check for size-calculation overflow.
2652 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
2654 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
2655 (x_session_initialize): Do not assume string length fits in int.
2657 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
2658 This is unlikely, but can occur if DPI is outlandish.
2660 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
2661 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
2663 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
2664 * xrdb.c (magic_file_p, search_magic_path):
2665 Omit last arg SUFFIX; it was always 0. All callers changed.
2666 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
2668 * xfont.c (xfont_match): Avoid need for strlen.
2670 * xfns.c: Don't assume strlen fits in int.

2673 * xdisp.c (message_log_check_duplicate): Return intmax_t,
2674 not unsigned long, as we prefer signed integers. All callers changed.
2675 Detect integer overflow in repeat count.
2676 (message_dolog): Don't assume print length fits in 39 bytes.
2677 (display_mode_element): Don't assume strlen fits in int.
2679 * termcap.c: Don't assume sizes fit in int and never overflow.
2680 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
2681 (gobble_line): Check for size-calculation overflow.
2683 * minibuf.c (Fread_buffer):
2684 * lread.c (intern, intern_c_string):
2685 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
2686 Don't assume string length fits in int.

2698 * filelock.c: Fix some buffer overrun and integer overflow issues.
2699 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
2700 Reformulate so as not to need the command string.
2701 Invoke gzip -cd rather than gunzip, as it's more portable.
2702 (lock_info_type, lock_file_1, lock_file):
2703 Don't assume pid_t and time_t fit in unsigned long.
2704 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
2705 (current_lock_owner): Prefer signed type for sizes.
2706 Use memcpy, not strncpy, where memcpy is what is really wanted.
2707 Don't assume (via atoi) that time_t and pid_t fit in int.
2708 Check for time_t and/or pid_t out of range, e.g., via a network share.
2709 Don't alloca where an auto var works fine.
2711 * fileio.c: Fix some integer overflow issues.
2712 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
2713 Don't assume string length fits in int.
2714 (directory_file_name): Don't assume string length fits in long.

2720 * coding.c (make_subsidiaries): Don't assume string length fits in int.
2722 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

2736 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
2738 * lread.c (invalid_syntax): Omit length argument.
2739 All uses changed. This doesn't fix a bug, but it simplifies the
2740 code away from its former Hollerith-constant appearance, and it's
2741 one less 'int' to worry about when looking at integer-overflow issues.
2742 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
2744 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
2745 This didn't break anything, but it didn't help either.
2746 It's confusing to put a bogus integer in a place where the actual
2747 value does not matter.
2748 (LIST_END_P): Remove unused macro and its bogus comment.
2749 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
2751 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
2752 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
2754 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
2755 We prefer signed types, and the value cannot exceed the EMACS_INT
2756 range anyway (because otherwise the length would not be representable).
2757 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
2758 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
2759 This avoids a GCC warning when WIDE_EMACS_INT.
2761 * indent.c (sane_tab_width): New function.
2762 (current_column, scan_for_column, Findent_to, position_indentation)
2763 (compute_motion): Use it. This is just for clarity.
2764 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
2766 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
2768 * lisp.h (lint_assume): New macro.
2769 * composite.c (composition_gstring_put_cache):
2770 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
2772 * editfns.c, insdel.c:
2773 Omit unnecessary forward decls, to simplify future changes.
2775 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
2777 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
2779 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
2780 Use much-faster test for byte-length change.
2781 Don't assume string byte-length fits in 'int'.
2782 Check that character arg fits in 'int'.
2783 (mapcar1): Declare byte as byte, for clarity.
2785 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
2787 * fns.c (concat): Catch string overflow earlier.
2788 Do not rely on integer wraparound.
2790 * dispextern.h (struct it.overlay_strings_charpos)
2791 (struct it.selective): Now EMACS_INT, not int.
2792 * xdisp.c (forward_to_next_line_start)
2793 (back_to_previous_visible_line_start)
2794 (reseat_at_next_visible_line_start, next_element_from_buffer):
2795 Don't arbitrarily truncate the value of 'selective' to int.
2797 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
2799 * composite.c: Don't truncate sizes to 'int'.
2800 (composition_gstring_p, composition_reseat_it)
2801 (composition_adjust_point): Use EMACS_INT, not int.
2802 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
2803 not EMACS_UINT, for indexes.
2805 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
2807 * buffer.c: Include <verify.h>.
2808 (struct sortvec.priority, struct sortstr.priority):
2809 Now EMACS_INT, not int.
2810 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
2811 (struct sortstr.size, record_overlay_string)
2812 (struct sortstrlist.size, struct sortlist.used):
2813 Don't truncate size to int.
2814 (record_overlay_string): Check for size-calculation overflow.
2815 (init_buffer_once): Check at compile-time, not run-time.
2817 2011-06-22 Jim Meyering <meyering@redhat.com>
2819 Don't leak an XBM-image-sized buffer
2820 * image.c (xbm_load): Free the image buffer after using it.
2822 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
2825 * composite.c (find_automatic_composition): Omit needless 'return 0;'
2826 that Sun C diagnosed.
2827 * fns.c (secure_hash): Fix pointer signedness issue.
2828 * intervals.c (static_offset_intervals): New function.
2829 (offset_intervals): Use it.
2831 2011-06-21 Leo Liu <sdl.web@gmail.com>
2834 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
2837 * fns.c (secure_hash): Rename from crypto_hash_function and change
2838 the first arg to accept symbols.
2839 (Fsecure_hash): New primitive.
2840 (syms_of_fns): New symbols.
2842 2011-06-20 Deniz Dogan <deniz@dogan.se>
2844 * process.c (Fset_process_buffer): Clarify return value in
2847 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
2849 * dispnew.c (add_window_display_history): Use BVAR.
2851 * xdisp.c (debug_method_add): Use BVAR.
2852 (check_window_end, dump_glyph_matrix, dump_glyph)
2853 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
2855 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
2858 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
2859 check till after the cache is created in init_frame_faces.
2861 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
2863 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
2865 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
2867 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
2868 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
2869 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
2871 Improve buffer-overflow checking (Bug#8873).
2872 * fileio.c (Finsert_file_contents):
2873 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
2874 Remove the old (too-loose) buffer overflow checks.
2875 They weren't needed, since make_gap checks for buffer overflow.
2876 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
2877 The old code merely checked for Emacs fixnum overflow, and relied
2878 on undefined (wraparound) behavior. The new code avoids undefined
2879 behavior, and also checks for ptrdiff_t and/or size_t overflow.
2881 * editfns.c (Finsert_char): Don't dump core with very negative counts.
2882 Tune. Don't use wider integers than needed. Don't use alloca.
2883 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
2885 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
2887 * insdel.c, lisp.h (buffer_overflow): New function.
2888 (insert_from_buffer_1, replace_range, replace_range_2):
2889 * insdel.c (make_gap_larger):
2890 * editfns.c (Finsert_char):
2891 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
2893 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
2895 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
2897 Integer overflow and signedness fixes (Bug#8873).
2899 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
2900 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
2902 * fileio.c: Don't assume EMACS_INT fits in off_t.
2903 (emacs_lseek): New static function.
2904 (Finsert_file_contents, Fwrite_region): Use it.
2905 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
2907 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
2909 * fns.c: Don't overflow int when computing a list length.
2910 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
2911 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
2912 truncation on 64-bit hosts. Check for QUIT every
2913 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
2914 faster and is responsive enough.
2915 (Flength): Report an error instead of overflowing an integer.
2916 (Fsafe_length): Return a float if the value is not representable
2917 as a fixnum. This shouldn't happen except in contrived situations.
2918 (Fnthcdr, Fsort): Don't assume list length fits in int.
2919 (Fcopy_sequence): Don't assume vector length fits in int.
2921 * alloc.c: Check that resized vectors' lengths fit in fixnums.
2922 (header_size, word_size): New constants.
2923 (allocate_vectorlike): Don't check size overflow here.
2924 (allocate_vector): Check it here instead, since this is the only
2925 caller of allocate_vectorlike that could cause overflow.
2926 Check that the new vector's length is representable as a fixnum.
2928 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
2929 The previous code was bogus. For example, next_almost_prime (32)
2930 returned 39, which is undesirable as it is a multiple of 3; and
2931 next_almost_prime (24) returned 25, which is a multiple of 5 so
2932 why was the code bothering to check for multiples of 7?
2934 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
2936 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
2938 Variadic C functions now count arguments with ptrdiff_t.
2939 This partly undoes my 2011-03-30 change, which replaced int with size_t.
2940 Back then I didn't know that the Emacs coding style prefers signed int.
2941 Also, in the meantime I found a few more instances where arguments
2942 were being counted with int, which may truncate counts on 64-bit
2943 machines, or EMACS_INT, which may be unnecessarily wide.
2944 * lisp.h (struct Lisp_Subr.function.aMANY)
2945 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
2946 Arg counts are now ptrdiff_t, not size_t.
2947 All variadic functions and their callers changed accordingly.
2948 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
2949 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
2950 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
2951 * callint.c (Fcall_interactively): Check arg count for overflow,
2952 to avoid potential buffer overrun. Use signed char, not 'int',
2953 for 'varies' array, so that we needn't bother to check its size
2954 calculation for overflow.
2955 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
2956 * eval.c (apply_lambda):
2957 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
2958 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
2959 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
2961 * callint.c (Fcall_interactively): Don't use index var as event count.
2963 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
2964 * mem-limits.h (SIZE): Remove; no longer used.
2966 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
2968 Remove unnecessary casts.
2969 * xterm.c (x_term_init):
2970 * xfns.c (x_set_border_pixel):
2971 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
2972 These aren't needed now that we assume ANSI C.
2974 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
2975 It's more likely to cause problems (due to unsigned overflow)
2978 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
2980 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
2982 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
2984 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
2986 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
2988 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
2990 GLYPH_CODE_FACE returns EMACS_INT, not int.
2991 * dispextern.h (merge_faces):
2992 * xfaces.c (merge_faces):
2993 * xdisp.c (get_next_display_element, next_element_from_display_vector):
2994 Don't assume EMACS_INT fits in int.
2996 * character.h (CHAR_VALID_P): Remove unused parameter.
2997 * fontset.c, lisp.h, xdisp.c: All uses changed.
2999 * editfns.c (Ftranslate_region_internal): Omit redundant test.
3001 * fns.c (concat): Minor tuning based on overflow analysis.
3002 This doesn't fix any bugs. Use int to hold character, instead
3003 of constantly refetching from Emacs object. Use XFASTINT, not
3004 XINT, for value known to be a character. Don't bother comparing
3005 a single byte to 0400, as it's always less.
3007 * floatfns.c (Fexpt):
3008 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
3010 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
3013 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
3015 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
3016 Without this fix, on a 64-bit host (aset S 0 4294967386) would
3017 incorrectly succeed when S was a string, because 4294967386 was
3018 truncated before it was used.
3020 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
3021 Otherwise, an out-of-range integer could cause undefined behavior
3024 * composite.c: Use int, not EMACS_INT, for characters.
3025 (fill_gstring_body, composition_compute_stop_pos): Use int, not
3026 EMACS_INT, for values that are known to be in character range.
3027 This doesn't fix any bugs but is the usual style inside Emacs and
3028 may generate better code on 32-bit machines.
3030 Make sure a 64-bit char is never passed to ENCODE_CHAR.
3031 This is for reasons similar to the recent CHAR_STRING fix.
3032 * charset.c (Fencode_char): Check that character arg is actually
3033 a character. Pass an int to ENCODE_CHAR.
3034 * charset.h (ENCODE_CHAR): Verify that the character argument is no
3035 wider than 'int', as a compile-time check to prevent future regressions
3038 * character.c (char_string): Remove unnecessary casts.
3040 Make sure a 64-bit char is never passed to CHAR_STRING.
3041 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
3042 by silently ignoring the top 32 bits, allowing some values
3043 that were far too large to be valid characters.
3044 * character.h: Include <verify.h>.
3045 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
3046 arguments are no wider than unsigned, as a compile-time check
3047 to prevent future regressions in this area.
3049 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
3050 (Fsubst_char_in_region):
3052 * xdisp.c (decode_mode_spec_coding):
3053 Adjust to CHAR_STRING's new requirement.
3054 * editfns.c (Finsert_char, Fsubst_char_in_region):
3055 * fns.c (concat): Check that character args are actually
3056 characters. Without this test, these functions did the wrong
3057 thing with wildly out-of-range values on 64-bit hosts.
3059 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
3060 These casts should not be needed on 32-bit hosts, either.
3061 * keyboard.c (read_char):
3062 * lread.c (Fload): Remove casts to unsigned.
3064 * lisp.h (UNSIGNED_CMP): New macro.
3065 This fixes comparison bugs on 64-bit hosts.
3066 (ASCII_CHAR_P): Use it.
3067 * casefiddle.c (casify_object):
3068 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
3069 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
3070 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
3071 * dispextern.h (FACE_FROM_ID):
3072 * keyboard.c (read_char): Use UNSIGNED_CMP.
3074 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
3075 not to EMACS_INT, to avoid GCC warning.
3077 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
3079 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
3080 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
3081 isn't needed on 32-bit machines.
3083 * buffer.c (Fgenerate_new_buffer_name):
3084 Use EMACS_INT for count, not int.
3085 (advance_to_char_boundary): Return EMACS_INT, not int.
3087 * data.c (Qcompiled_function): Now static.
3089 * window.c (window_body_lines): Now static.
3091 * image.c (gif_load): Rename local to avoid shadowing.
3093 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
3094 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
3095 * alloc.c (make_save_value): Integer argument is now of type
3097 (mark_object): Use ptrdiff_t, not int.
3098 * lisp.h (pD): New macro.
3099 * print.c (print_object): Use it.
3101 * alloc.c: Use EMACS_INT, not int, to count objects.
3102 (total_conses, total_markers, total_symbols, total_vector_size)
3103 (total_free_conses, total_free_markers, total_free_symbols)
3104 (total_free_floats, total_floats, total_free_intervals)
3105 (total_intervals, total_strings, total_free_strings):
3106 Now EMACS_INT, not int. All uses changed.
3107 (Fgarbage_collect): Compute overall total using a double, so that
3108 integer overflow is less likely to be a problem. Check for overflow
3109 when converting back to an integer.
3110 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
3111 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
3112 These were 'int' variables that could overflow on 64-bit hosts;
3113 they were never used, so remove them instead of repairing them.
3114 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
3115 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
3116 Previously, this ceilinged at INT_MAX, but that doesn't work on
3118 (allocate_pseudovector): Don't use EMACS_INT when int would do.
3120 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
3121 (allocate_vectorlike): Check for ptrdiff_t overflow.
3122 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
3123 when a (possibly-narrower) signed value would do just as well.
3124 We prefer using signed arithmetic, to avoid comparison confusion.
3126 * alloc.c: Catch some string size overflows that we were missing.
3127 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
3128 for convenience in STRING_BYTES_MAX.
3129 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
3130 The definition here is exact; the one in lisp.h was approximate.
3131 (allocate_string_data): Check for string overflow. This catches
3132 some instances we weren't catching before. Also, it catches
3133 size_t overflow on (unusual) hosts where SIZE_MAX <= min
3134 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
3135 and ptrdiff_t and EMACS_INT are both 64 bits.
3137 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
3138 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
3139 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
3141 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
3143 * alloc.c (Fmake_string): Check for out-of-range init.
3145 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
3147 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
3149 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
3151 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
3152 xg_get_default_scrollbar_width.
3154 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
3155 (int_gtk_range_get_value): Move to the scroll bar part of the file.
3156 (style_changed_cb): Call update_theme_scrollbar_width and call
3157 x_set_scroll_bar_default_width and xg_frame_set_char_size for
3158 all frames (Bug#8505).
3159 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
3160 Call gtk_window_set_resizable if HAVE_GTK3.
3161 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
3162 and height if HAVE_GTK3 (Bug#8505).
3163 (scroll_bar_width_for_theme): New variable.
3164 (update_theme_scrollbar_width): New function.
3165 (xg_get_default_scrollbar_width): Move code to
3166 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
3167 (xg_initialize): Call update_theme_scrollbar_width.
3169 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
3171 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
3173 2011-06-12 Martin Rudalics <rudalics@gmx.at>
3175 * frame.c (make_frame): Call other_buffer_safely instead of
3178 * window.c (temp_output_buffer_show): Call display_buffer with
3179 second argument Vtemp_buffer_show_specifiers and reset latter
3180 immediately after the call.
3181 (Vtemp_buffer_show_specifiers): New variable.
3182 (auto_window_vscroll_p, next_screen_context_lines)
3183 (Vscroll_preserve_screen_position): Remove leading asterisks from
3186 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
3188 Fix minor problems found by GCC 4.6.0 static checking.
3189 * buffer.c (Qclone_number): Remove for now, as it's unused.
3190 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
3191 (record_buffer): Remove unused local.
3192 * frame.c (other_visible_frames, frame_buffer_list): Now static.
3193 (set_frame_buffer_list): Remove; unused.
3194 * frame.h (other_visible_frames): Remove decl.
3195 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
3196 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
3197 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
3199 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
3200 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
3201 Define only if HAVE_GPM.
3202 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
3203 (update_hints_inhibit): Remove; never set. All uses removed.
3204 * widgetprv.h (emacsFrameClassRec): Remove decl.
3205 * window.c (delete_deletable_window): Now returns void, since it
3206 wasn't returning anything.
3207 (compare_window_configurations): Remove unused locals.
3208 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
3209 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
3210 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
3211 the same widths as pointers. This follows up on the 2011-05-06 patch.
3212 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
3213 * xterm.h: Likewise.
3214 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
3216 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
3218 * makefile.w32-in: Update dependencies.
3219 (LISP_H): Add lib/intprops.h.
3221 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
3223 * image.c (gif_load): Add animation frame delay to the metadata.
3224 (syms_of_image): Use DEFSYM. New symbol `delay'.
3226 2011-06-11 Martin Rudalics <rudalics@gmx.at>
3228 * window.c (delete_deletable_window): Re-add.
3229 (Fset_window_configuration): Rewrite to handle dead buffers and
3230 consequently deletable windows.
3231 (window_tree, Fwindow_tree): Remove. Supply functionality in
3233 (compare_window_configurations): Simplify code.
3235 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
3237 * image.c (imagemagick_load_image): Fix type mismatch.
3238 (Fimagemagick_types): Likewise.
3240 * window.h (replace_buffer_in_windows): Declare.
3242 2011-06-11 Martin Rudalics <rudalics@gmx.at>
3244 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
3245 Qclone_number. Remove external declaration of Qdelete_window.
3246 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
3248 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
3249 Run Qbuffer_list_update_hook if allowed.
3250 (Fother_buffer): Rewrite doc-string. Major rewrite for new
3251 buffer list implementation.
3252 (other_buffer_safely): New function.
3253 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
3254 calls to replace_buffer_in_windows and
3255 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
3257 (record_buffer): Inhibit quitting and rewrite using quittable
3258 functions. Run Qbuffer_list_update_hook if allowed.
3259 (Frecord_buffer, Funrecord_buffer): New functions.
3260 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
3261 Move switch-to-buffer to window.el.
3262 (bury-buffer): Move to window.el.
3263 (Vbuffer_list_update_hook): New variable.
3265 * lisp.h (other_buffer_safely): Add prototype in buffer.c
3268 * window.h (resize_frame_windows): Move up in code.
3269 (Fwindow_frame): Remove EXFUN.
3270 (replace_buffer_in_all_windows): Remove prototype.
3271 (replace_buffer_in_windows_safely): Add prototype.
3273 * window.c: Declare Qdelete_window static again. Move down
3274 declaration of select_count.
3275 (Fnext_window, Fprevious_window): Rewrite doc-strings.
3276 (Fother_window): Move to window.el.
3277 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
3278 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
3279 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
3281 (replace_buffer_in_windows): Implement by calling
3282 Qreplace_buffer_in_windows.
3283 (replace_buffer_in_all_windows): Remove with some functionality
3284 moved into replace_buffer_in_windows_safely.
3285 (replace_buffer_in_windows_safely): New function.
3286 (select_window_norecord, select_frame_norecord): Move in front

3754 (compute_display_string_pos, compute_display_string_end):
3756 (push_it): Accept second argument POSITION, where pop_it should
3757 jump to continue iteration.
3758 (reseat_1): Initialize bidi_it.disp_pos.
3760 * keyboard.c (adjust_point_for_property): Adjust the call to

3771 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
3773 Malloc failure behavior now depends on size of allocation.
3774 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
3775 * lisp.h: Change signatures accordingly.
3776 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
3777 All callers changed. (Bug#8762)
3779 * gnutls.c: Use Emacs's memory allocators.
3780 Without this change, the gnutls library would invoke malloc etc.
3781 directly, which causes problems on non-SYNC_INPUT hosts, and which
3782 runs afoul of improving memory_full behavior. (Bug#8761)
3783 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
3784 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
3785 xfree instead of the default malloc, realloc, free.
3786 (Fgnutls_boot): No need to check for memory allocation failure,
3787 since xmalloc does that for us.
3789 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
3790 * category.c (hash_get_category_set):
3791 * ccl.c (ccl_driver):

3803 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
3804 (Fsxhash, Fgethash, Fputhash, Fmaphash):
3805 * image.c (make_image, search_image_cache, lookup_image)
3806 (xpm_put_color_table_h):
3807 * lisp.h (struct Lisp_Hash_Table):
3808 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
3809 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
3810 for hashes and hash indexes, instead of 'unsigned' and 'int'.
3811 * alloc.c (allocate_vectorlike):
3812 Check for overflow in vector size calculations.
3813 * ccl.c (ccl_driver):
3814 Check for overflow when converting EMACS_INT to int.
3815 * fns.c, image.c: Remove unnecessary static decls that would otherwise
3816 need to be updated by these changes.
3817 * fns.c (make_hash_table, maybe_resize_hash_table):
3818 Check for integer overflow with large hash tables.
3819 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
3820 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
3821 (SXHASH_REDUCE): New macro.
3822 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
3823 Use it instead of discarding useful hash info with large hash values.
3824 (sxhash_float): New function.
3825 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
3826 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
3827 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
3828 Rewrite to use FIXNUM_BITS, as this simplifies things.
3829 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
3830 Adjust signatures to match updated version of code.
3831 (consing_since_gc): Now EMACS_INT, since a single hash table can
3832 use more than INT_MAX bytes.
3834 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
3836 Make it possible to build with GCC-4.6+ -O2 -flto.
3838 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
3840 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
3842 * minibuf.c (get_minibuffer, read_minibuf_unwind):
3843 Call minibuffer-inactive-mode.
3845 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
3847 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
3848 Update dependencies.
3850 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3852 * data.c (init_data): Remove code for UTS, this system is not
3855 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3857 Don't force ./temacs to start in terminal mode.
3859 * frame.c (make_initial_frame): Initialize faces in all cases, not
3860 only when CANNOT_DUMP is defined.
3861 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
3863 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3865 * dispnew.c (add_window_display_history): Use const for the string
3866 pointer. Remove declaration, not needed.
3868 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3870 Use 'inline', not 'INLINE'.
3871 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
3872 * alloc.c, fontset.c (INLINE): Remove.
3873 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
3874 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
3875 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
3876 * gmalloc.c (register_heapinfo): Use inline unconditionally.
3877 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
3879 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3881 Make it possible to run ./temacs.
3883 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
3884 syms_of_callproc does the same thing. Remove test for
3885 "initialized", do it in the caller.
3886 * emacs.c (main): Avoid calling set_initial_environment when dumping.
3888 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
3890 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
3891 (read_minibuf): Use get_minibuffer.
3892 (syms_of_minibuf): Use DEFSYM.
3893 (Qmetadata): New var.
3894 * data.c (Qbuffer): Don't make it static.
3895 (syms_of_data): Use DEFSYM.
3897 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3899 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
3900 (CCL_CODE_MIN): New macro.
3902 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
3904 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
3906 * eval.c (Qdebug): Now static.
3907 * lisp.h (Qdebug): Remove decl. This reverts a part of the
3908 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
3909 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
3911 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3913 * image.c: Various fixes to ImageMagick code comments.
3914 (Fimagemagick_types): Doc fix.
3916 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
3918 Minor fixes prompted by GCC 4.6.0 warnings.
3920 * xselect.c (converted_selections, conversion_fail_tag): Now static.
3922 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
3923 (x_clipboard_manager_save_all): Move extern decl to ...
3924 * xterm.h: ... here, so that it can be checked for consistency.
3926 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3928 * xselect.c (x_clipboard_manager_save_frame)
3929 (x_clipboard_manager_save_all): New functions.
3930 (Fx_clipboard_manager_save): Lisp function deleted.
3932 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
3933 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
3935 * xterm.h: Update prototype.
3937 2011-05-28 William Xu <william.xwl@gmail.com>
3939 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
3942 2011-05-28 Jim Meyering <meyering@redhat.com>
3944 Avoid a sign-extension bug in crypto_hash_function.
3945 * fns.c (to_uchar): Define.
3946 (crypto_hash_function): Use it to convert some newly-signed
3947 variables to unsigned, to avoid sign-extension bugs. For example,
3948 without this change, (md5 "truc") would evaluate to
3949 45723a2aff78ff4fff7fff1114760e62 rather than the expected
3950 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
3951 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
3953 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3955 Integer overflow fixes.
3957 * dbusbind.c: Serial number integer overflow fixes.
3958 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
3959 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
3960 to hold a serial number that is too large for a fixnum.
3961 (Fdbus_method_return_internal, Fdbus_method_error_internal):
3962 Check for serial numbers out of range. Decode any serial number
3963 that was so large that it became a float. (Bug#8722)
3965 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
3966 (Fdbus_call_method, Fdbus_call_method_asynchronously):
3967 Use XFASTINT rather than XUINT when numbers are nonnegative.
3968 (xd_append_arg, Fdbus_method_return_internal):
3969 (Fdbus_method_error_internal): Likewise. Also, for unsigned
3970 arguments, check that Lisp number is nonnegative, rather than
3971 silently wrapping negative numbers around. (Bug#8722)
3972 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
3975 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
3977 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
3979 ccl: add integer overflow checks
3980 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
3981 (IN_INT_RANGE): New macros.
3982 (ccl_driver): Use them to check for integer overflow when
3983 decoding a CCL program. Many of the new checks are whether XINT (x)
3984 fits in int; it doesn't always, on 64-bit hosts. The new version
3985 doesn't catch all possible integer overflows, but it's an
3986 improvement. (Bug#8719)
3988 * alloc.c (make_event_array): Use XINT, not XUINT.
3989 There's no need for unsigned here.
3991 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
3992 This follows up to the 2011-05-06 change that substituted uintptr_t
3993 for EMACS_INT. This case wasn't caught back then.
3995 Rework Fformat to avoid integer overflow issues.
3996 * editfns.c: Include <float.h> unconditionally, as it's everywhere
3997 now (part of C89). Include <verify.h>.
3998 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
3999 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
4000 (Fformat): Avoid the prepass trying to compute sizes; it was only
4001 approximate and thus did not catch overflow reliably. Instead, walk
4002 through the format just once, formatting and computing sizes as we go,
4003 checking for integer overflow at every step, and allocating a larger
4004 buffer as needed. Keep track separately whether the format is
4005 multibyte. Keep only the most-recently calculated precision, rather
4006 than them all. Record whether each argument has been converted to
4007 string. Use EMACS_INT, not int, for byte and char and arg counts.
4008 Support field widths and precisions larger than INT_MAX. Avoid
4009 sprintf's undefined behavior with conversion specifications such as %#d
4010 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
4011 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
4012 formatting out-of-range floating point numbers with int
4015 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
4017 * data.c: Avoid integer truncation in expressions involving floats.
4018 * data.c: Include <intprops.h>.
4019 (arith_driver): When there's an integer overflow in an expression
4020 involving floating point, convert the integers to floating point
4021 so that the resulting value does not suffer from catastrophic
4022 integer truncation. For example, on a 64-bit host (* 4
4023 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
4024 Do not rely on undefined behavior after integer overflow.
4026 merge count_size_as_multibyte, parse_str_to_multibyte
4027 * character.c, character.h (count_size_as_multibyte):
4028 Rename from parse_str_to_multibyte; all uses changed.
4029 Check for integer overflow.
4030 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
4031 since it's now a duplicate of the other. This is more of
4032 a character than a buffer op, so better that it's in character.c.
4033 * fns.c, print.c: Adjust to above changes.
4035 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
4037 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
4039 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
4041 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
4042 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
4043 (x_clipboard_manager_save): Now static.
4044 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
4046 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
4047 (crypto_hash_function): Now static.
4048 Fix pointer signedness problems. Avoid unnecessary initializations.
4050 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
4052 * termhooks.h (Vselection_alist): Make it terminal-local.
4054 * terminal.c (create_terminal): Initialize it.
4056 * xselect.c: Support for clipboard managers.
4057 (Vselection_alist): Move to termhooks.h as terminal-local var.

4061 (x_handle_selection_request, lisp_data_to_selection_data)
4062 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
4063 (x_own_selection, x_get_local_selection, x_convert_selection):
4064 New arg, specifying work frame. Use terminal-local Vselection_alist.
4065 (some_frame_on_display): Delete unused function.
4066 (Fx_own_selection_internal, Fx_get_selection_internal)
4067 (Fx_disown_selection_internal, Fx_selection_owner_p)
4068 (Fx_selection_exists_p): New optional frame arg.
4069 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
4070 (x_handle_selection_clear): Don't treat other terminals with the
4071 same keyboard specially. Use the terminal-local Vselection_alist.
4072 (x_clear_frame_selections): Use Frun_hook_with_args.
4074 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
4076 * xterm.h: Add support for those atoms.
4078 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
4080 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
4081 (converted_selections, conversion_fail_tag): New global variables.
4082 (x_selection_request_lisp_error): Free the above.
4083 (x_get_local_selection): Remove unnecessary code.
4084 (x_reply_selection_request): Args changed; handle arbitrary array
4085 of converted selections stored in converted_selections.
4086 Separate the XChangeProperty and SelectionNotify steps.
4087 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
4088 (x_convert_selection): New function.
4089 (x_handle_selection_event): Simplify.
4090 (x_get_foreign_selection): Don't ignore incoming requests while
4091 waiting for an answer; this will fail when we implement
4092 SAVE_TARGETS, and seems unnecessary anyway.
4093 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
4094 (Vx_sent_selection_functions): Doc fix.
4096 2011-05-26 Leo Liu <sdl.web@gmail.com>
4098 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
4100 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

4107 and fringe_bitmap_periodic_p.
4109 * fringe.c (get_fringe_bitmap_data): New function.
4110 (draw_fringe_bitmap_1, update_window_fringes): Use it.
4111 (update_window_fringes): Record periodicity of fringe bitmap in glyph
4112 row. Mark glyph row for fringe update if periodicity changed.
4114 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
4115 for fringe update unless it has periodic bitmap.
4117 2011-05-25 Kenichi Handa <handa@m17n.org>

4170 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
4172 * systime.h (Time): Define only if emacs is defined.
4173 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
4174 where the include path doesn't have X11/X.h by default. See
4175 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.

4209 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
4211 * menu.c: Include limits.h (fixes the MS-Windows build broken by
4212 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
4214 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
4216 Fix some integer overflow issues, such as string length overflow.
4218 * insdel.c (count_size_as_multibyte): Check for string overflow.
4220 * character.c (lisp_string_width): Check for string overflow.
4221 Use EMACS_INT, not int, for string indexes and lengths; in
4222 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
4223 the resulting string length overflows an EMACS_INT; instead,
4224 report a string overflow if no precision given. When checking for
4225 precision exhaustion, use a check that cannot possibly have
4226 integer overflow. (Bug#8675)
4227 * character.h (lisp_string_width): Adjust to new signature.
4229 * alloc.c (string_overflow): New function.
4230 (Fmake_string): Use it. This doesn't change behavior, but saves
4231 a few bytes and will simplify future changes.
4232 * character.c (string_escape_byte8): Likewise.
4233 * lisp.h (string_overflow): New decl.
4235 Fixups, following up to the user-interface timestamp change.
4236 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
4237 for UI timestamps, instead of unsigned long.
4238 * msdos.c (mouse_get_pos): Likewise.
4239 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
4240 * w32gui.h (Time): Define by including "systime.h" rather than by
4241 declaring it ourselves. (Bug#8664)
4243 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
4244 * image.c (clear_image_cache): Likewise.
4246 * term.c (term_mouse_position): Don't assume time_t wraparound.
4248 Be more systematic about user-interface timestamps.
4249 Before, the code sometimes used 'Time', sometimes 'unsigned long',
4250 and sometimes 'EMACS_UINT', to represent these timestamps.
4251 This change causes it to use 'Time' uniformly, as that's what X uses.
4252 This makes the code easier to follow, and makes it easier to catch
4253 integer overflow bugs such as Bug#8664.
4254 * frame.c (Fmouse_position, Fmouse_pixel_position):
4255 Use Time, not unsigned long, for user-interface timestamps.
4256 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
4257 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
4258 * keyboard.h (last_event_timestamp): Likewise.
4259 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
4260 * menu.h (xmenu_show): Likewise.
4261 * term.c (term_mouse_position): Likewise.
4262 * termhooks.h (struct input_event.timestamp): Likewise.
4263 (struct terminal.mouse_position_hook): Likewise.
4264 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
4265 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
4266 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
4267 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
4269 * menu.h, termhooks.h: Include "systime.h", for Time.
4271 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
4272 Don't assume that the difference between two unsigned long values
4273 can fit into an integer. At this point, we know button_down_time
4274 <= event->timestamp, so the difference must be nonnegative, so
4275 there's no need to cast the result if double-click-time is
4276 nonnegative, as it should be; check that it's nonnegative, just in
4277 case. This bug is triggered when events are more than 2**31 ms
4278 apart (about 25 days). (Bug#8664)
4280 * xselect.c (last_event_timestamp): Remove duplicate decl.
4281 (x_own_selection): Remove needless cast to unsigned long.
4283 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
4284 that always fit in int. Use a sentinel instead of a counter, to
4285 avoid a temp and to allay GCC's concerns about possible int overflow.
4286 * frame.h (struct frame): Use int for menu_bar_items_used
4287 instead of EMACS_INT, since it always fits in int.
4289 * menu.c (grow_menu_items): Check for int overflow.
4291 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
4293 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
4294 Before, the code was not consistent. These values cannot exceed
4295 2**31 - 1 so there's no need to make them unsigned.
4296 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
4297 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
4298 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
4300 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
4302 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
4303 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
4304 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
4305 presumably because the widths might not match.
4307 * window.c (size_window): Avoid needless test at loop start.
4309 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
4311 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
4313 2011-05-12 Drew Adams <drew.adams@oracle.com>
4315 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
4317 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4319 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
4320 `width' to `bar_area_x' and `bar_area_width', respectively.
4321 (x_scroll_run): Take account of fringe background extension.
4323 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
4324 Rename local vars `left' and `width' to `bar_area_x' and
4325 `bar_area_width', respectively.
4326 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
4327 background extension.
4329 2011-05-10 Jim Meyering <meyering@redhat.com>
4331 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
4333 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
4335 * image.c (Finit_image_library): Return t for built-in image types,
4336 like pbm and xbm. (Bug#8640)
4338 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
4340 * w32menu.c (set_frame_menubar): Fix submenu allocation.
4342 2011-05-07 Eli Zaretskii <eliz@gnu.org>
4344 * w32console.c (Fset_screen_color): Doc fix.
4345 (Fget_screen_color): New function.
4346 (syms_of_ntterm): Defsubr it.
4348 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
4349 unlink the temporary file if Fcall_process didn't create it in the
4351 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
4352 child process will be redirected to a file specified with `:file'.
4353 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
4354 cue to call_process_cleanup not to close that handle.
4356 2011-05-07 Ben Key <bkey76@gmail.com>
4358 * makefile.w32-in: The bootstrap-temacs rule now makes use of
4359 one of two shell specific rules, either bootstrap-temacs-CMD or
4360 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
4361 to the previous implementation of the bootstrap-temacs rule.
4362 The bootstrap-temacs-CMD rule is similar to the previous
4363 implementation of the bootstrap-temacs rule except that it
4364 makes use of the ESC_CFLAGS variable instead of the CFLAGS
4367 These changes, along with some changes to nt/configure.bat,
4368 nt/gmake.defs, and nt/nmake.defs, are required to extend my
4369 earlier fix to add support for --cflags and --ldflags options
4370 that include quotes so that it works whether make uses cmd or
4373 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
4375 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
4376 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
4378 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
4379 a string. Handle both cases.
4380 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
4381 (Fdbus_register_method): Use Qinvalid_function.
4383 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
4385 * makefile.w32-in: Update dependencies.
4386 (LISP_H): Add inttypes.h and stdin.h.
4387 (PROCESS_H): Add unistd.h.
4389 2011-05-06 Eli Zaretskii <eliz@gnu.org>
4391 * lread.c: Include limits.h (fixes the MS-Windows build broken by
4392 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
4394 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
4396 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
4398 * term.c (vfatal): Remove stray call to va_end.
4399 It's not needed and the C Standard doesn't allow it here anyway.
4401 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
4402 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
4404 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
4407 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
4409 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
4411 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
4413 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
4415 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
4417 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
4418 * charset.c (Fdefine_charset_internal): Don't initialize
4419 charset.code_space[15]. The value was garbage, on hosts with
4420 32-bit int (Bug#8600).
4422 * lread.c (read_integer): Be more consistent with string-to-number.
4423 Use string_to_number to do the actual conversion; this avoids
4424 rounding errors and fixes some other screwups. Without this fix,
4425 for example, #x1fffffffffffffff was misread as -2305843009213693952.
4426 (digit_to_number): Move earlier, for benefit of read_integer.
4427 Return -1 if the digit is out of range for the base, -2 if it is
4428 not a digit in any supported base. (Bug#8602)
4430 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
4432 * dispnew.c (scrolling_window): Return 1 if we scrolled,
4433 to match comment at start of function. This also removes a
4434 GCC warning about overflow in a 32+64-bit port.
4436 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
4438 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
4439 Reported by Stefan Monnier in
4440 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
4441 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
4442 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
4444 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
4445 (EMACS_UINTPTR): Likewise, with uintptr_t.
4447 * lisp.h: Prefer 64-bit EMACS_INT if available.
4448 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
4449 on 32-bit hosts that have 64-bit int, so that they can access
4451 However, temporarily disable this change unless the temporary
4452 symbol WIDE_EMACS_INT is defined.
4454 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
4456 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
4457 This removes an assumption that EMACS_INT and long are the same
4458 width as pointers. The assumption is true for Emacs porting targets
4459 now, but we want to make other targets possible.
4460 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
4461 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
4462 In the rest of the code, change types of integers that hold casted
4463 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
4464 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
4465 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
4466 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
4467 No need to cast type when ORing.
4468 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
4469 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
4470 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
4471 assume EMACS_INT is the same width as char *.
4472 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
4473 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
4474 Remove no-longer-needed casts.
4475 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
4476 (xg_tool_bar_help_callback, xg_make_tool_item):
4477 Use EMACS_INTPTR to hold an integer
4478 that will be cast to void *; this can avoid a GCC warning
4479 if EMACS_INT is not the same width as void *.
4480 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
4481 * xdisp.c (display_echo_area_1, resize_mini_window_1):
4482 (current_message_1, set_message_1):
4483 Use a local to convert to proper width without a cast.
4484 * xmenu.c (dialog_selection_callback): Likewise.
4486 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
4487 Also, don't assume VALBITS / RAND_BITS is less than 5,
4488 and don't rely on undefined behavior when shifting a 1 left into
4490 * lisp.h (get_random): Change signature to match.
4492 * lread.c (hash_string): Use size_t, not int, for hash computation.
4493 Normally we prefer signed values; but hashing is special, because
4494 it's better to use unsigned division on hash table sizes so that
4495 the remainder is nonnegative. Also, size_t is the natural width
4496 for hashing into memory. The previous code used 'int', which doesn't
4497 retain enough info to hash well into very large tables.
4498 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
4500 * dbusbind.c: Don't possibly lose pointer info when converting.
4501 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
4502 Use XPNTR rather than XHASH, so that the high-order bits of
4503 the pointer aren't lost when converting through void *.
4505 * eval.c (Fautoload): Don't double-shift a pointer.
4507 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
4509 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
4511 * gnutls.c (DEF_GNUTLS_FN):
4512 * image.c (DEF_IMGLIB_FN): Make function pointers static.
4514 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
4516 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
4519 2011-05-05 Eli Zaretskii <eliz@gnu.org>
4521 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
4522 New version that can reserve upto 2GB of heap space.
4524 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
4526 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
4528 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
4530 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
4531 `gnutls_certificate_set_x509_key_file'.
4533 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
4535 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
4536 Update dependencies.
4538 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4540 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
4541 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
4542 Remove unused parameter `fildes'.
4543 * process.c (read_process_output, send_process): Don't pass it.
4545 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4547 Fix previous change: the library cache is defined in w32.c.
4548 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
4549 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
4551 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4553 Implement dynamic loading of GnuTLS on Windows.
4555 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
4556 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
4557 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
4560 * gnutls.c (Qgnutls_dll): Define.
4561 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
4562 (gnutls_*): Declare function pointers.
4563 (init_gnutls_functions): New function to initialize function pointers.
4564 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
4565 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
4566 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
4567 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
4568 (emacs_gnutls_write, emacs_gnutls_read)
4569 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
4570 (Fgnutls_available_p): New function.
4571 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
4572 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
4573 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
4575 * image.c: Include w32.h.
4576 (Vimage_type_cache): Delete.
4577 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
4578 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
4579 (w32_delayed_load): Move to w32.c.
4581 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
4583 * w32.c (QCloaded_from, Vlibrary_cache): Define.
4584 (w32_delayed_load): Move from image.c. When loading a library, record
4585 its filename in the :loaded-from property of the library id.
4586 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
4587 Initialize and staticpro them.
4588 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
4590 * process.c: Include lisp.h before w32.h, not after.
4591 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
4592 instead of gnutls_record_check_pending.
4594 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
4596 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
4598 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
4599 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
4602 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
4604 * xterm.c (x_set_frame_alpha): Do not set property on anything
4605 else than FRAME_X_OUTER_WINDOW (Bug#8608).
4607 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
4609 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
4611 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
4613 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
4614 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
4615 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)
4616 (gnutls_global_initialized, Qgnutls_bootprop_priority)

4618 (Qgnutls_bootprop_callbacks, Qgnutls_bootprop_loglevel)
4619 (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags)
4620 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
4621 (Qgnutls_bootprop_callbacks_verify): Make static.
4623 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
4625 * callproc.c: Indentation fixup.
4627 * sysdep.c (wait_for_termination_1): Make static.
4628 (wait_for_termination, interruptible_wait_for_termination):
4629 Move after wait_for_termination_1.
4631 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
4633 * sysdep.c (interruptible_wait_for_termination): New function
4634 which is like wait_for_termination, but allows keyboard
4637 * callproc.c (Fcall_process): Add (:file "file") as an option for
4639 (Fcall_process_region): Ditto.
4641 2011-04-30 Eli Zaretskii <eliz@gnu.org>
4643 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
4644 rather than `XVECTOR (FOO)->size'.
4646 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
4647 inttypes.h, as a gnulib replacement is used if it not available in

4653 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
4654 of MOST_POSITIVE_FIXNUM. (Bug#8528)
4656 * coding.c (coding_alloc_by_realloc): Error out if destination
4657 will grow beyond MOST_POSITIVE_FIXNUM.
4658 (decode_coding_emacs_mule): Abort if there isn't enough place in
4659 charbuf for the composition carryover bytes. Reserve an extra
4660 space for up to 2 characters produced in a loop.
4661 (decode_coding_iso_2022): Abort if there isn't enough place in
4662 charbuf for the composition carryover bytes.
4664 2011-04-21 Eli Zaretskii <eliz@gnu.org>
4666 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
4667 aborting when %lld or %lll format is passed.
4668 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
4669 %llo or %llx format is passed. (Bug#8545)
4671 * window.c (window_scroll_line_based): Use a marker instead of
4672 simple variables to record original value of point. (Bug#7952)
4674 * doprnt.c (doprnt): Fix the case where a multibyte sequence
4675 produced by %s or %c overflows available buffer space. (Bug#8545)
4677 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
4679 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
4680 (SIZE_MAX): Move defn after all includes, as they might #define it.
4682 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4684 * w32.c (init_environment): Warn about defaulting HOME to C:\.
4686 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4688 * keyboard.c (Qdelayed_warnings_hook): Define.
4689 (command_loop_1): Run `delayed-warnings-hook'
4690 if Vdelayed_warnings_list is non-nil.
4691 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
4692 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
4694 2011-04-28 Eli Zaretskii <eliz@gnu.org>
4696 * doprnt.c (doprnt): Don't return value smaller than the buffer
4697 size if the message was truncated. (Bug#8545).
4699 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4701 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
4702 (Fx_window_property): #if-0 the whole functions, not just the bodies.
4704 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
4706 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
4708 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
4710 * makefile.w32-in: Update dependencies.
4712 2011-04-27 Eli Zaretskii <eliz@gnu.org>
4714 Improve `doprnt' and its usage. (Bug#8545)
4715 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
4716 `format_end'. Remove support for %l as a conversion specifier.
4717 Don't use xrealloc. Improve diagnostics when the %l size modifier
4718 is used. Update the commentary.
4720 * eval.c (verror): Simplify calculation of size_t.
4722 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
4725 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
4727 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
4730 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
4732 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
4733 This makes this file independent of the recent pseudovector change.
4735 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
4737 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
4739 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
4740 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
4741 Remove unused local.
4742 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
4744 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
4745 GCC 4.6.0 optimizes based on type-based alias analysis.
4746 For example, if b is of type struct buffer * and v of type struct
4747 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
4748 != &v->size, and therefore "v->size = 1; b->size = 2; return
4749 v->size;" must therefore return 1. This assumption is incorrect
4750 for Emacs, since it type-puns struct Lisp_Vector * with many other
4751 types. To fix this problem, this patch adds a new type struct
4752 vectorlike_header that documents the constraints on layout of vectors
4753 and pseudovectors, and helps optimizing compilers not get fooled
4754 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
4755 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
4756 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
4758 (XSETPVECTYPE): Rewrite in terms of new macro.
4759 (XSETPVECTYPESIZE): New macro, specifying both type and size.
4760 This is a bit clearer, and further avoids the possibility of
4761 undesirable aliasing.
4762 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
4763 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
4764 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
4765 since Lisp_Subr is a special case (no "next" field).
4766 (ASIZE): Now uses header.size rather than size.
4767 All previous uses of XVECTOR (foo)->size replaced to use this macro,
4768 to avoid the hassle of writing XVECTOR (foo)->header.size.
4769 (struct vectorlike_header): New type.
4770 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
4771 object, to help avoid aliasing.
4772 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
4773 (SUBRP): Likewise, since Lisp_Subr is a special case.
4774 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
4775 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
4776 (struct Lisp_Hash_Table): Combine first two members into a single
4777 struct vectorlike_header member. All uses of "size" and "next" members
4778 changed to be "header.size" and "header.next".
4779 * buffer.h (struct buffer): Likewise.
4780 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
4781 * frame.h (struct frame): Likewise.
4782 * process.h (struct Lisp_Process): Likewise.
4783 * termhooks.h (struct terminal): Likewise.
4784 * window.c (struct save_window_data, struct saved_window): Likewise.
4785 * window.h (struct window): Likewise.
4786 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
4787 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
4788 * buffer.c (init_buffer_once): Likewise.
4789 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
4791 * process.c (Fformat_network_address): Use local var for size,
4794 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
4796 Make the Lisp reader and string-to-float more consistent (Bug#8525)
4797 * data.c (atof): Remove decl; no longer used or needed.
4798 (digit_to_number): Move to lread.c.
4799 (Fstring_to_number): Use new string_to_number function, to be
4800 consistent with how the Lisp reader treats infinities and NaNs.
4801 Do not assume that floating-point numbers represent EMACS_INT
4802 without losing information; this is not true on most 64-bit hosts.
4803 Avoid double-rounding errors, by insisting on integers when
4804 parsing non-base-10 numbers, as the documentation specifies.
4805 * lisp.h (string_to_number): New decl, replacing ...
4806 (isfloat_string): Remove.
4807 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
4808 (read1): Do not accept +. and -. as integers; this
4809 appears to have been a coding error. Similarly, do not accept
4810 strings like +-1e0 as floating point numbers. Do not report
4811 overflow for integer overflows unless the base is not 10 which
4812 means we have no simple and reliable way to continue.
4813 Break out the floating-point parsing into a new
4814 function string_to_number, so that Fstring_to_number parses
4815 floating point numbers consistently with the Lisp reader.
4816 (digit_to_number): Move here from data.c. Make it static inline.
4817 (E_CHAR, EXP_INT): Remove, replacing with ...
4818 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
4819 (string_to_number): New function, replacing isfloat_string.
4820 This function checks for valid syntax and produces the resulting
4821 Lisp float number too. Rework it so that string-to-number
4822 no longer mishandles examples like "1.0e+". Use strtoumax,
4823 so that overflow for non-base-10 numbers is reported only when
4824 there's no portable and simple way to convert to floating point.
4826 * textprop.c (set_text_properties_1): Rewrite for clarity,
4827 and to avoid GCC warning about integer overflow.
4829 * intervals.h (struct interval): Use EMACS_INT for members
4830 where EMACS_UINT might cause problems. See
4831 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
4832 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
4833 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
4835 (offset_intervals): Tell GCC not to worry about length overflow
4836 when negating a negative length.
4838 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
4839 (overrun_check_free): Likewise.
4841 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
4842 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
4845 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4846 (gnutls_make_error): Rename local to avoid shadowing.
4847 (gnutls_emacs_global_deinit): ifdef out; not used.
4848 (Fgnutls_boot): Use const for pointer to readonly storage.
4849 Comment out unused local. Fix pointer signedness problems.
4851 * lread.c (openp): Don't stuff size_t into an 'int'.
4852 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
4853 about possible signed overflow.
4855 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4856 (GDK_KEY_g): Don't define if already defined.
4857 (xg_prepare_tooltip): Avoid pointer signedness problem.
4858 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
4860 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
4861 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
4863 * xfns.c (Fx_window_property): Simplify a bit,
4864 to make a bit faster and to avoid GCC 4.6.0 warning.
4865 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
4867 * fns.c (internal_equal): Don't assume size_t fits in int.
4869 * alloc.c (compact_small_strings): Tighten assertion a little.
4871 Replace pEd with more-general pI, and fix some printf arg casts.
4872 * lisp.h (pI): New macro, generalizing old pEd macro to other
4873 conversion specifiers. For example, use "...%"pI"d..." rather
4874 than "...%"pEd"...".
4875 (pEd): Remove. All uses replaced with similar uses of pI.
4876 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
4877 * alloc.c (check_pure_size): Don't overflow by converting size to int.
4878 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
4879 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
4880 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
4881 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
4882 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
4884 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
4885 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
4886 * print.c (safe_debug_print, print_object): Likewise.
4887 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
4889 Use pI instead of if-then-else-abort. Use %p to avoid casts,
4890 avoiding the 0 flag, which is not portable.
4891 * process.c (Fmake_network_process): Use pI to avoid cast.
4892 * region-cache.c (pp_cache): Likewise.
4893 * xdisp.c (decode_mode_spec): Likewise.
4894 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
4895 behavior on 64-bit hosts with printf arg.
4896 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
4897 (x_stop_queuing_selection_requests): Likewise.
4898 (x_get_window_property): Don't truncate byte count to an 'int'
4901 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
4902 here, since it parses constructs like leading '-' and spaces,
4903 which are not wanted; and it overflows with large numbers.
4904 Instead, simply match F[0-9]+, which is what is wanted anyway.
4906 * alloc.c: Remove unportable assumptions about struct layout.
4907 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
4908 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
4909 (allocate_vectorlike, make_pure_vector): Use the new macros,
4910 plus offsetof, to remove unportable assumptions about struct layout.
4911 These assumptions hold on all porting targets that I know of, but
4912 they are not guaranteed, they're easy to remove, and removing them
4913 makes further changes easier.
4915 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
4916 This doesn't fix a bug but makes the code clearer.
4917 (string_overrun_cookie): Now const. Use initializers that
4918 don't formally overflow signed char, to avoid warnings.
4919 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
4920 can cause Emacs to crash when string overrun checking is enabled.
4921 (allocate_buffer): Don't assume sizeof (struct buffer) is a
4922 multiple of sizeof (EMACS_INT); it need not be, if
4923 alignof(EMACS_INT) < sizeof (EMACS_INT).
4924 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
4926 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
4928 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
4930 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
4932 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
4933 supposed to be handshaking. (Bug#8556)
4934 Reported by Paul Eggert <eggert@cs.ucla.edu>.

4946 * alloc.c (check_sblock, check_string_bytes)
4947 (check_string_free_list): Convert to standard C.
4949 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
4951 * w32.c (emacs_gnutls_push): Fix typo.
4953 2011-04-25 Eli Zaretskii <eliz@gnu.org>
4955 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
4956 "cast to pointer from integer of different size".
4958 Improve doprnt and its use in verror. (Bug#8545)
4959 * doprnt.c (doprnt): Document the set of format control sequences
4960 supported by the function. Use SAFE_ALLOCA instead of always
4963 * eval.c (verror): Don't limit the buffer size at size_max-1, that
4964 is one byte too soon. Don't use xrealloc; instead xfree and
4967 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
4969 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
4972 * gnutls.c: Renamed global_initialized to
4973 gnutls_global_initialized. Added internals for the
4974 :verify-hostname-error, :verify-error, and :verify-flags
4975 parameters of `gnutls-boot' and documented those parameters in the
4976 docstring. Start callback support.
4977 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
4978 unless a fatal error occurred. Call gnutls_alert_send_appropriate
4979 on error. Return error code.
4980 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
4981 (emacs_gnutls_read): Likewise.
4982 (Fgnutls_boot): Return handshake error code.
4983 (emacs_gnutls_handle_error): New function.
4984 (wsaerror_to_errno): Likewise.
4986 * w32.h (emacs_gnutls_pull): Add prototype.

5051 * doprnt.c: Include limits.h.
5052 (SIZE_MAX): New macro.
5053 (doprnt): Return a size_t value. 2nd arg is now size_t.
5054 Many local variables are now size_t instead of int or unsigned.
5055 Improve overflow protection. Support `l' modifier for integer
5056 conversions. Support %l conversion. Don't assume an EMACS_INT
5057 argument for integer conversions and for %c.
5059 * lisp.h (doprnt): Restore prototype.
5061 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
5064 * Makefile.in (base_obj): Add back doprnt.o.
5066 * deps.mk (doprnt.o): Add back prerequisites.
5067 (callint.o): Depend on character.h.
5069 * eval.c (internal_lisp_condition_case): Include the handler
5070 representation in the error message.
5071 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
5072 when breaking from the loop.
5074 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
5076 * callint.c (Fcall_interactively): When displaying error message
5077 about invalid control letter, pass the character's codepoint, not
5078 a pointer to its multibyte form. Improve display of the character
5079 in octal and display also its hex code.
5081 * character.c (char_string): Use %x to display the (unsigned)
5082 codepoint of an invalid character, to avoid displaying a bogus
5085 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
5086 `error', not SYMBOL_NAME itself.
5088 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
5089 character arguments to `error'.
5091 * charset.c (check_iso_charset_parameter): Fix incorrect argument
5092 to `error' in error message about FINAL_CHAR argument. Make sure
5093 FINAL_CHAR is a character, and use %c when it is passed as
5094 argument to `error'.
5096 2011-04-23 Eli Zaretskii <eliz@gnu.org>
5098 * s/ms-w32.h (localtime): Redirect to sys_localtime.
5100 * w32.c: Include <time.h>.

5160 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier

5643 so that it's not optimized away.
5644 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
5645 * dispextern.h (bidi_dump_cached_states): Remove, since it's
5646 exported only to the debugger.
5648 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
5649 * atimer.h (run_all_atimers): Remove; not exported.
5651 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
5652 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
5653 was inaccessible from Lisp.
5654 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
5655 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
5657 alloc.c: Import and export fewer symbols, and remove unused items.
5658 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
5660 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
5661 it's not optimized away by whole-program optimization.

5663 (catchlist, handlerlist, mark_backtrace):
5664 Declare only if BYTE_MARK_STACK.

5669 (n_float_blocks, float_free_list, cons_block, cons_block_index):
5670 (cons_free_list, last_marked_index):
5672 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
5673 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
5674 (mark_backtrace): Define only if BYTE_MARK_STACK.
5675 * xdisp.c (message_enable_multibyte): Now static.
5677 Declare Lisp_Object Q* variables to be 'static' if not exported.
5678 This makes it easier for human readers (and static analyzers)
5679 to see whether these variables are used from other modules.
5680 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
5681 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
5682 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

5690 Remove decls of unexported vars.
5691 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
5693 * lisp.h (DEFINE_FUNC): Make sname 'static'.
5695 Make Emacs functions such as Fatom 'static' by default.
5696 This makes it easier for human readers (and static analyzers)
5697 to see whether these functions can be called from other modules.
5698 DEFUN now defines a static function. To make the function external
5699 so that it can be used in other C modules, use the new macro DEFUE.
5700 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
5701 (Finit_image_library):
5702 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
5703 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
5704 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
5705 Remove decls, since these functions are now static.
5706 (Funintern, Fget_internal_run_time): New decls, since these functions
5707 were already external.
5709 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

5716 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
5717 Mark functions with DEFUE instead of DEFUN,
5718 if they are used in other modules.

5720 decls for now-static functions.
5721 * buffer.h (Fdelete_overlay): Remove decl.

5760 when at ZV. (Bug#8487)
5762 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
5764 * charset.c (Fclear_charset_maps): Use xfree instead of free.
5766 * keyboard.c (parse_tool_bar_item): Likewise.
5767 * sound.c (sound_cleanup, alsa_close): Likewise.
5768 * termcap.c (tgetent): Likewise.
5769 * xfns.c (x_default_font_parameter): Likewise.
5770 * xsettings.c (read_and_apply_settings): Likewise.
5772 * alloc.c (overrun_check_malloc, overrun_check_realloc)
5773 (overrun_check_free): Protoize.
5775 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
5777 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
5778 since callers should never pass a negative size.
5779 Change the signature to match that of plain 'read' and 'write'; see
5780 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
5781 * lisp.h: Update prototypes of emacs_write and emacs_read.
5783 2011-04-11 Eli Zaretskii <eliz@gnu.org>
5785 * xdisp.c (redisplay_window): Don't try to determine the character
5786 position of the scroll margin if the window start point w->startp
5787 is outside the buffer's accessible region. (Bug#8468)
5789 2011-04-10 Eli Zaretskii <eliz@gnu.org>
5791 Fix write-region and its subroutines for buffers > 2GB.
5792 * fileio.c (a_write, e_write): Modify declaration of arguments and
5793 local variables to support buffers larger than 2GB.
5794 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
5796 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
5797 argument, local variables, and return value.
5799 * lisp.h: Update prototypes of emacs_write and emacs_read.
5801 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
5803 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
5805 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
5807 Fix more problems found by GCC 4.6.0's static checks.
5809 * xdisp.c (vmessage): Use a better test for character truncation.
5811 * charset.c (load_charset_map): <, not <=, for optimization,
5812 and to avoid potential problems with integer overflow.
5813 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
5814 * casetab.c (set_identity, shuffle): Likewise.
5815 * editfns.c (Fformat): Likewise.
5816 * syntax.c (skip_chars): Likewise.
5818 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
5819 This also lets GCC 4.6.0 generate slightly better loop code.
5821 * callint.c (Fcall_interactively): <, not <=, for optimization.
5822 (Fcall_interactively): Count the number of arguments produced,
5823 not the number of arguments given. This is simpler and lets GCC
5824 4.6.0 generate slightly better code.
5826 * ftfont.c: Distingish more carefully between FcChar8 and char.
5827 The previous code passed unsigned char * to a functions like
5828 strlen and xstrcasecmp that expect char *, which does not
5829 conform to the C standard.
5830 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
5831 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
5832 char * when the C standard requires it.
5834 * keyboard.c (read_char): Remove unused var.
5836 * eval.c: Port to Windows vsnprintf (Bug#8435).
5838 (SIZE_MAX): Define if the headers do not.
5839 (verror): Do not give up if vsnprintf returns a negative count.
5840 Instead, grow the buffer. This ports to Windows vsnprintf, which
5841 does not conform to C99. Problem reported by Eli Zaretskii.
5842 Also, simplify the allocation scheme, by avoiding the need for
5843 calling realloc, and removing the ALLOCATED variable.
5845 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
5847 Remove invocations of doprnt, as Emacs now uses vsnprintf.
5848 But keep the doprint source code for now, as we might revamp it
5849 and use it again (Bug#8435).
5850 * lisp.h (doprnt): Remove.
5851 * Makefile.in (base_obj): Remove doprnt.o.
5852 * deps.mk (doprnt.o): Remove.
5854 error: Print 32- and 64-bit integers portably (Bug#8435).
5855 Without this change, on typical 64-bit hosts error ("...%d...", N)
5856 was used to print both 32- and 64-bit integers N, which relied on
5858 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
5860 * lisp.h (error, verror): Mark as printf-like functions.
5861 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
5862 Report overflow in size calculations when allocating printf buffer.
5863 Do not truncate output string at its first null byte.
5864 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
5865 Truncate the output at a character boundary, since vsnprintf does not
5867 * charset.c (check_iso_charset_parameter): Convert internal
5868 character to string before calling 'error', since %c now has the
5870 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
5871 overflow when computing char to be passed to 'error'. Do not
5872 pass Lisp_Object to 'error'; pass the integer instead.
5873 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
5874 formatted with plain %d.
5876 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
5878 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
5880 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
5882 * xterm.c (x_catch_errors): Remove duplicate declaration.
5884 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
5886 * xdisp.c, lisp.h (message_nolog): Remove; unused.
5888 2011-04-10 Jim Meyering <meyering@redhat.com>
5890 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
5891 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
5892 return ssize_t not "int", and use size_t as the buffer length.
5893 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
5894 * gnutls.h: Update declarations.
5895 * process.c (read_process_output): Use ssize_t, to match.
5896 (send_process): Likewise.
5898 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
5900 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
5902 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
5904 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
5905 Use unsigned char, to match FcChar8 type definition.
5907 * xterm.c (handle_one_xevent):
5908 * xmenu.c (create_and_show_popup_menu):
5909 * xselect.c (x_decline_selection_request)
5910 (x_reply_selection_request): Avoid type-punned deref of X events.
5912 2011-04-09 Eli Zaretskii <eliz@gnu.org>
5914 Fix some uses of `int' instead of EMACS_INT.
5915 * search.c (string_match_1, fast_string_match)
5916 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
5917 (scan_buffer, find_next_newline_no_quit)
5918 (find_before_next_newline, search_command, Freplace_match)
5919 (Fmatch_data): Make some `int' variables be EMACS_INT.
5921 * xdisp.c (display_count_lines): 3rd argument and return value now
5922 EMACS_INT. All callers changed.
5923 (pint2hrstr): Last argument is now EMACS_INT.
5925 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
5926 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

5939 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
5941 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
5942 (encode_invocation_designation): Last argument P_NCHARS is now
5944 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
5945 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
5947 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
5950 * ccl.c (Fccl_execute_on_string): Declare some variables
5953 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

5965 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
5967 * keyboard.c (read_char): Call Lisp function help-form-show,
5968 instead of using internal_with_output_to_temp_buffer.

5970 (syms_of_keyboard): Use DEFSYM macro.
5972 * print.c (internal_with_output_to_temp_buffer): Function deleted.

5985 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
5987 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
5989 Fix more problems found by GCC 4.6.0's static checks.
5991 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
5993 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
5995 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
5997 * xdisp.c (vmessage): Mark as a printf-like function.
5999 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
6001 * sound.c (sound_warning): Don't crash if arg contains a printf format.
6003 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
6004 printf-like functions.
6005 (tiff_load): Add casts to remove these marks before passing them
6006 to system-supplied API.
6008 * eval.c (Fsignal): Remove excess argument to 'fatal'.
6010 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
6011 This avoids several warnings with gcc -Wstrict-overflow.
6012 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
6013 directly, rather than having caller test rule sign. This avoids
6014 some unnecessary tests.
6015 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
6016 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
6017 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

6028 breaking out part of COMPOSITION_DECODE_RULE.
6029 (COMPOSITION_DECODE_RULE): Use it.
6030 * composite.c (get_composition_id): Remove unused local vars,
6031 by using the new macro.
6033 * textprop.c (set_text_properties_1): Change while to do-while,
6034 since the condition is always true at first.

6069 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
6070 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
6071 can always succeed if overflow has undefined behavior.
6073 * search.c (boyer_moore, wordify): Remove vars set but not used.
6074 (wordify): Omit three unnecessary tests.
6076 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
6077 All callers changed. This avoids the need for an unused var.
6079 * casefiddle.c (casify_region): Remove var that is set but not used.
6081 * dired.c (file_name_completion): Remove var that is set but not used.
6083 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
6085 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
6086 (Finsert_file_contents): Remove unnecessary code checking fd.
6088 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
6089 Check for integer overflow on size calculations.

6101 * image.c (lookup_image): Remove var that is set but not used.
6102 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
6104 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
6105 that are set but not used.
6107 * xfns.c (make_invisible_cursor): Don't return garbage
6108 if XCreateBitmapFromData fails (Bug#8410).
6110 * xselect.c (x_get_local_selection, x_handle_property_notify):
6111 Remove vars that are set but not used.
6113 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
6114 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
6116 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
6117 Remove var that is set but not used.
6118 (scroll_bar_windows_size): Now size_t, not int.
6119 (x_send_scroll_bar_event): Use size_t, not int, for sizes.

6128 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
6129 All callers changed.
6130 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
6131 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
6132 (decode_coding_charset): Remove vars that are set but not used.
6134 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
6135 that is set but not used.
6137 * print.c (print_object): Remove var that is set but not used.
6139 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
6140 The gnulib version avoids calling malloc in the usual case,
6141 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
6142 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
6143 * filelock.c (current_lock_owner): Likewise.
6144 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
6145 * sysdep.c: Include allocator.h, careadlinkat.h.
6146 (emacs_no_realloc_allocator): New static constant.
6147 (emacs_readlink): New function.
6148 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

6153 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
6154 first non-nil return value).

6168 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
6169 and thereabouts. All callers changed.
6170 (get_per_char_metric): Remove parameter `f', unused since
6171 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

6176 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
6177 (ns_get_family): Likewise.
6179 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

6183 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
6185 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
6188 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
6190 Add lexical binding.
6192 * window.c (Ftemp_output_buffer_show): New fun.
6193 (Fsave_window_excursion):
6194 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
6196 * lread.c (lisp_file_lexically_bound_p): New function.
6197 (Fload): Bind Qlexical_binding.
6198 (readevalloop): Remove `evalfun' arg.
6199 Bind Qinternal_interpreter_environment.
6200 (Feval_buffer): Bind Qlexical_binding.
6201 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
6203 (syms_of_lread): Declare `lexical-binding'.
6205 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
6207 * keyboard.c (eval_dyn): New fun.
6208 (menu_item_eval_property): Use it.
6210 * image.c (parse_image_spec): Use Ffunctionp.
6212 * fns.c (concat, mapcar1): Accept byte-code-functions.
6214 * eval.c (Fsetq): Handle lexical vars.
6215 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
6216 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
6217 (FletX, Flet): Obey lexical binding.
6218 (Fcommandp): Handle closures.
6219 (Feval): New `lexical' arg.
6220 (eval_sub): New function extracted from Feval. Use it almost
6221 everywhere where Feval was used. Look up vars in lexical env.
6223 (Ffunctionp): Move from subr.el.
6224 (Ffuncall): Handle closures.
6225 (apply_lambda): Remove `eval_flags'.
6226 (funcall_lambda): Handle closures and new byte-code-functions.
6227 (Fspecial_variable_p): New function.
6228 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
6229 but without exporting it to Lisp.
6231 * doc.c (Fdocumentation, store_function_docstring):
6232 * data.c (Finteractive_form): Handle closures.
6234 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
6237 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
6239 (exec_byte_code): New function extracted from Fbyte_code to handle new
6240 calling convention for byte-code-functions. Add new byte-codes.
6242 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
6244 * alloc.c (Fmake_symbol): Init new `declared_special' field.
6246 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
6248 * xdisp.c (redisplay_internal): Fix prototype.
6250 2011-03-31 Eli Zaretskii <eliz@gnu.org>
6252 * xdisp.c (SCROLL_LIMIT): New macro.
6253 (try_scrolling): Use it when setting scroll_limit.
6254 Limit scrolling to 100 screen lines.
6255 (redisplay_window): Even when falling back on "recentering",
6256 position point in the window according to scroll-conservatively,
6257 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
6259 (try_scrolling): When point is above the window, allow searching
6260 as far as scroll_max, or one screenful, to compute vertical
6261 distance from PT to the scroll margin position. This prevents
6262 try_scrolling from unnecessarily failing when
6263 scroll-conservatively is set to a value slightly larger than the
6264 window height. Clean up the case of PT below the margin at bottom
6265 of window: scroll_max can no longer be INT_MAX. When aggressive
6266 scrolling is in use, don't let point enter the opposite scroll
6267 margin as result of the scroll.
6268 (syms_of_xdisp) <scroll-conservatively>: Document the
6269 threshold of 100 lines for never-recentering scrolling.

6276 (message_log_check_duplicate): Remove parameters `prev_bol' and
6277 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
6278 (redisplay_internal): Remove parameter `preserve_echo_area',
6279 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
6281 * indent.c (Fvertical_motion):
6282 * window.c (window_scroll_pixel_based, Frecenter):
6283 Don't pass `need_y_p' to `move_it_by_lines'.
6285 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
6287 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
6288 steal a few bits to be more compact.
6289 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
6290 Remove unneeded casts.
6292 * bytecode.c (Fbyte_code): CAR and CDR can GC.
6294 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
6296 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
6297 binding" message (bug#7967).

6301 Fix more problems found by GCC 4.6.0's static checks.
6303 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
6304 Remove unused local var.
6306 * editfns.c (Fmessage_box): Remove unused local var.
6308 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
6309 (note_mode_line_or_margin_highlight, note_mouse_highlight):
6310 Omit unused local vars.
6311 * window.c (shrink_windows): Omit unused local var.
6312 * menu.c (digest_single_submenu): Omit unused local var.
6313 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
6314 Omit unused local var.
6316 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
6317 Don't assume string length fits in int.
6318 (keyremap_step, read_key_sequence): Use size_t for sizes.
6319 (read_key_sequence): Don't check last_real_key_start redundantly.
6321 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
6322 instead of alloca (Bug#8344).
6324 * eval.c (Fbacktrace): Don't assume nargs fits in int.
6325 (Fbacktrace_frame): Don't assume nframes fits in int.
6327 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
6329 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
6332 * term.c (produce_glyphless_glyph): Remove unnecessary test.
6334 * cm.c (calccost): Turn while-do into do-while, for clarity.
6336 * keyboard.c (syms_of_keyboard): Use the same style as later
6337 in this function when indexing through an array. This also
6338 works around GCC bug 48267.
6340 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
6342 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
6344 * chartab.c (sub_char_table_ref_and_range): Redo for slight
6345 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
6347 * keyboard.c, keyboard.h (num_input_events): Now size_t.
6348 This avoids undefined behavior on integer overflow, and is a bit
6349 more convenient anyway since it is compared to a size_t variable.
6351 Variadic C functions now count arguments with size_t, not int.
6352 This avoids an unnecessary limitation on 64-bit machines, which
6353 caused (substring ...) to crash on large vectors (Bug#8344).
6354 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.

6364 * frame.c (x_set_frame_parameters): Likewise.
6365 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
6366 0 if not found, not -1. All callers changed.
6368 * alloc.c (garbage_collect): Don't assume stack size fits in int.
6369 (stack_copy_size): Now size_t, not int.
6370 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
6372 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
6374 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
6375 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
6376 All callers changed.
6378 * lisp.h (multibyte_char_to_unibyte):
6379 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
6380 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

6395 Vcommand_hook_internal.

6398 (funcall_nil, funcall_not): New functions.
6399 (run_hook_with_args): Call each function through a `funcall' argument.

6414 All callers changed.
6416 * w32.c (_wsa_errlist): Use braces for struct initializers.
6418 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
6419 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
6420 All callers changed.

6565 * term.c (Fsuspend_tty, Fresume_tty):
6566 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
6567 * window.c (temp_output_buffer_show):

6573 * cmds.c (internal_self_insert):
6574 * callint.c (Fcall_interactively):
6575 * buffer.c (Fkill_all_local_variables):
6576 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
6578 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
6579 unconditionnaly since it does the check itself.
6581 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
6583 Fix more problems found by GCC 4.5.2's static checks.
6585 * coding.c (encode_coding_raw_text): Avoid unnecessary test
6586 the first time through the loop, since we know p0 < p1 then.
6587 This also avoids a gcc -Wstrict-overflow warning.
6589 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
6590 leading to a memory leak, possible in functions like
6591 load_charset_map_from_file that can allocate an unbounded number
6592 of objects (Bug#8318).
6594 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
6595 that could (at least in theory) be that large.
6597 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
6598 This is less likely to overflow, and avoids undefined behavior if
6599 overflow does occur. All callers changed. Use strtoul to scan
6600 for the unsigned long integer.
6601 (pint2hrstr): Simplify and tune code slightly.
6602 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
6604 * scroll.c (do_scrolling): Work around GCC bug 48228.
6605 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

6610 This also avoids a warning with gcc -Wstrict-overflow.
6612 * fileio.c (Fcopy_file): Report error if fchown or fchmod
6615 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
6617 * process.c (Fmake_network_process): Use socklen_t, not int,
6618 where POSIX says socklen_t is required in portable programs.
6619 This fixes a porting bug on hosts like 64-bit HP-UX, where
6620 socklen_t is wider than int (Bug#8277).
6621 (Fmake_network_process, server_accept_connection):
6622 (wait_reading_process_output, read_process_output):
6625 * process.c: Rename or move locals to avoid shadowing.

6635 Make tparam.h and terminfo.c consistent.
6636 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
6637 Include tparam.h instead, since it declares them.
6638 * cm.h (PC): Remove extern decl; tparam.h now does this.
6639 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
6640 * terminfo.c: Include tparam.h, to check interfaces.
6641 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
6642 (tparam): Adjust signature to match interface in tparam.h;
6643 this removes some undefined behavior. Check that outstring and len
6644 are zero, which they always are with Emacs.
6645 * tparam.h (PC, BC, UP): New extern decls.
6647 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
6648 (xftfont_open): Rename locals to avoid shadowing.
6650 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

6668 with a FIXME (Bug#8290).
6670 character.h: Rename locals to avoid shadowing.

6673 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
6674 (BUF_DEC_POS): Be more systematic about renaming local temporaries
6677 * textprop.c (property_change_between_p): Remove; unused.
6679 * intervals.c (interval_start_pos): Now static.
6681 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

6684 Rename locals to avoid shadowing.
6686 * sound.c (wav_play, au_play, Fplay_sound_internal):
6687 Fix pointer signedness.
6688 (alsa_choose_format): Remove unused local var.
6689 (wav_play): Initialize a variable to 0, to prevent undefined
6690 behavior (Bug#8278).
6692 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
6694 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
6696 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
6697 clobbering (Bug#8298).
6698 * sysdep.c (sys_subshell): Likewise.
6699 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
6701 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
6702 This should get cleaned up, so that child_setup has the
6703 same signature on all platforms.
6705 * callproc.c (call_process_cleanup): Now static.
6706 (relocate_fd): Rename locals to avoid shadowing.
6708 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
6710 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
6711 not to be necessary, and produces flickering.
6713 2011-03-20 Glenn Morris <rgm@gnu.org>
6715 * config.in: Remove file.
6717 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
6719 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
6720 are now in src/globals.h.
6721 (syms_of_minibuf): Remove spurious & from previous change.
6723 2011-03-20 Leo <sdl.web@gmail.com>
6725 * minibuf.c (completing-read-function): New variable.
6726 (completing-read-default): Rename from completing-read.
6727 (completing-read): Call completing-read-function.

6732 Read color file from absolute filename (bug#8250).
6734 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
6736 * makefile.w32-in: Update dependencies.
6738 2011-03-17 Eli Zaretskii <eliz@gnu.org>
6740 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

6747 (sigchld_handler): Now static.
6749 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.

6751 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
6752 * s/cygwin.h (PTY_ITERATION): Likewise.
6753 * s/darwin.h (PTY_ITERATION): Likewise.

6756 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
6757 * process.c (allocate_pty): Don't declare stb unless it's needed.
6759 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
6760 (CONSTANTLIM): Remove; unused.
6761 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
6762 Define only if needed.
6764 * unexelf.c (unexec): Name an expression,
6765 to avoid gcc -Wbad-function-cast warning.
6766 Use a different way to cause a compilation error if anyone uses
6767 n rather than nn, a way that does not involve shadowing.
6768 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
6770 * deps.mk (unexalpha.o): Remove; unused.
6772 New file unexec.h, the (simple) interface for unexec (Bug#8267).
6773 * unexec.h: New file.
6774 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
6775 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
6777 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
6778 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
6779 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.

6789 * lread.c (read1): Rewrite so as not to use empty "else".
6790 (Fload, readevalloop, read1): Rename locals to avoid shadowing.
6792 * print.c (Fredirect_debugging_output): Fix pointer signedess.
6794 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
6795 warning when compiling print.c.
6797 * font.c (font_unparse_fcname): Abort in an "impossible" situation
6798 instead of using an uninitialized var.
6799 (font_sort_entities): Mark var as initialized.

6835 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
6836 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,

6858 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
6859 Rename locals to avoid shadowing.
6860 (mark_stack): Move local variables into the #ifdef region where
6862 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
6863 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
6865 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
6866 (GC_STRING_CHARS): Remove; not used.
6867 (Fmemory_limit): Cast sbrk's returned value to char *.

6872 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
6874 Use functions, not macros, for up- and down-casing (Bug#8254).
6875 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6876 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
6877 to use the following functions instead of these macros.
6878 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
6879 EMACS_INT, since callers assume the returned value fits in int.
6880 (upcase1): Likewise, for UPCASE_TABLE.
6881 (uppercasep, lowercasep, upcase): New static inline functions.
6882 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

6887 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
6888 (regex_compile, re_search_2, re_match_2_internal):
6889 Remove unused local vars.
6890 (FREE_VAR): Rewrite so as not to use empty "else",
6891 which gcc can warn about.
6892 (regex_compile, re_match_2_internal): Mark locals as initialized.
6893 (RETALLOC_IF): Define only if needed.
6894 (WORDCHAR_P): Likewise. This one is never needed, but is used
6895 only in a comment talking about a compiler bug, so put inside
6896 the #if 0 of that comment.
6897 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
6898 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
6901 * search.c (boyer_moore): Rename locals to avoid shadowing.
6902 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
6903 (PREV_CHAR_BOUNDARY): Likewise.
6905 * search.c (simple_search): Remove unused var.
6907 * dired.c (compile_pattern): Move decl from here ...

6911 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
6913 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
6915 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
6916 Rename locals to avoid shadowing.
6917 (Fvertical_motion): Mark locals as initialized.
6919 * casefiddle.c (casify_object, casify_region): Now static.
6920 (casify_region): Mark local as initialized.
6922 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
6924 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
6925 New macros, so that the caller can use some names other than
6926 gcpro1, gcpro2, etc.
6927 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
6929 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
6930 argument, for consistency with GCPRO2_VAR, etc: it is now the
6931 prefix of the variable, not the variable itself. All uses
6933 * dired.c (directory_files_internal, file_name_completion):
6934 Rename locals to avoid shadowing.
6936 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
6937 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
6938 dired.c's scmp function, had undefined behavior.
6939 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6940 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
6941 * buffer.h: ... to here, because these macros use current_buffer,
6942 and the new implementation with inline functions needs to have
6943 current_buffer in scope now, rather than later when the macros
6945 (downcase, upcase1): New static inline functions.
6946 (DOWNCASE, UPCASE1): Reimplement using these functions.
6947 This avoids undefined behavior in expressions like
6948 DOWNCASE (x) == DOWNCASE (y), which previously suffered
6949 from race conditions in accessing the global variables
6950 case_temp1 and case_temp2.
6951 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
6952 * lisp.h (case_temp1, case_temp2): Remove their decls.
6953 * character.h (ASCII_CHAR_P): Move from here ...
6954 * lisp.h: ... to here, so that the inline functions mentioned
6957 * dired.c (directory_files_internal_unwind): Now static.
6959 * fileio.c (file_name_as_directory, directory_file_name):
