[bpt/emacs.git] / src / ChangeLog
1 2011-09-07 Eli Zaretskii <eliz@gnu.org>
2
3 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
4 only under bidi iteration.
5
6 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7
8 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
9
10 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
11
12 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13 Without this fix, the command to link temacs failed due to an
14 undefined symbol __builtin_isnan. This is because
15 /usr/include/iso/math_c99.h #defines isnan(x) to
16 __builtin_isnan(x), but the bundled gcc, which identifies itself
17 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
18 a __builtin_isnan.
19 * floatfns.c (isnan): #undef, and then #define to a clone of
20 what's in data.c.
21 (Fisnan): Always define, since it's always available now.
22 (syms_of_floatfns): Always define isnan at the Lisp level.
23
24 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
25
26 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
27
28 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
29
30 * fileio.c: Fix bugs with large file offsets (Bug#9428).
31 The previous code assumed that file offsets (off_t values) fit in
32 EMACS_INT variables, which is not true on typical 32-bit hosts.
33 The code messed up by falsely reporting buffer overflow in cases
34 such as (insert-file-contents "big" nil 1 2) into an empty buffer
35 when "big" contains more than 2**29 bytes, even though this
36 inserts just one byte and does not overflow the buffer.
37 (Finsert_file_contents): Store file offsets as off_t
38 values, not as EMACS_INT values. Check for overflow when
39 converting between EMACS_INT and off_t. When checking for
40 buffer overflow or for overlap, take the offsets into account.
41 Don't use EMACS_INT for small values where int suffices.
42 When checking for overlap, fix a typo: ZV was used where
43 ZV_BYTE was intended.
44 (Fwrite_region): Don't assume off_t fits into 'long'.
45 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
46
47 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
48
49 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
50
51 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
52
53 sprintf-related integer and memory overflow issues (Bug#9412).
54
55 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
56 (esprintf, exprintf, evxprintf): New functions.
57 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
58 (cmd_error): kbd macro iterations count is now EMACS_INT, not int.
59 (modify_event_symbol): Do not assume that the length of
60 name_alist_or_stem is safe to alloca and fits in int.
61 (Fexecute_extended_command): Likewise for function name and binding.
62 (Frecursion_depth): Wrap around reliably on integer overflow.
63 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
64 since some callers pass EMACS_INT values.
65 (Fsingle_key_description): Don't crash if symbol name contains more
66 than MAX_ALLOCA bytes.
67 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
68 (get_minibuffer): Arg is now EMACS_INT, not int.
69 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
70 (esprintf, exprintf, evxprintf): New decls.
71 * window.h (command_loop_level, minibuf_level): Reflect API changes.
72
73 * dbusbind.c (signature_cat): New function.
74 (xd_signature, Fdbus_register_signal):
75 Do not overrun buffer; instead, report string overflow.
76
77 * dispnew.c (add_window_display_history): Don't overrun buffer.
78 Truncate instead; this is OK since it's just a log.
79
80 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
81 even if the time zone offset is outlandishly large.
82 Don't mishandle offset == INT_MIN.
83
84 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
85 when creating daemon; the previous buffer-overflow check was incorrect.
86
87 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
88 which has the guts of the old verror function.
89
90 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
91 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
92
93 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
94 (font_unparse_xlfd): Don't blindly alloca long strings.
95 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
96 fits in int, when using sprintf. Use single snprintf to count
97 length of string rather than counting it via multiple sprintfs;
98 that's simpler and more reliable.
99 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
100 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
101 sprintf, in case result does not fit in int.
102
103 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
104 (fontset_from_font): Print it.
105
106 * frame.c (tty_frame_count): Now printmax_t, not int.
107 (make_terminal_frame, set_term_frame_name): Print it.
108 (x_report_frame_params): In X, window IDs are unsigned long,
109 not signed long, so print them as unsigned.
110 (validate_x_resource_name): Check for implausibly long names,
111 and don't assume name length fits in 'int'.
112 (x_get_resource_string): Don't blindly alloca invocation name;
113 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
114 not fit in int.
115
116 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
117 (xg_check_special_colors, xg_set_geometry):
118 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
119
120 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
121 Use esprintf, not sprintf, in case result does not fit in int.
122
123 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
124 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
125 it as a large positive number.
126 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
127 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
128
129 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
130 in case result does not fit in int.
131
132 * print.c (float_to_string): Detect width overflow more reliably.
133 (print_object): Make sprintf buffer a bit bigger, to avoid potential
134 buffer overrun. Don't assume list length fits in 'int'. Treat
135 print length of 0 as 0, not as infinity; to be consistent with other
136 uses of print length in this function. Don't overflow print length
137 index. Don't assume hash table size fits in 'long', or that
138 vectorlike size fits in 'unsigned long'.
139
140 * process.c (make_process): Use printmax_t, not int, to format
141 process-name gensyms.
142
143 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
144
145 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
146 to avoid potential buffer overrun.
147
148 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
149 if X resource line is longer than 512 bytes.
150
151 * xfns.c (x_window): Make sprintf buffer a bit bigger
152 to avoid potential buffer overrun.
153
154 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
155
156 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
157
158 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
159
160 Integer overflow fixes for scrolling, etc.
161 Without these, Emacs silently mishandles large integers sometimes.
162 For example, "C-u 4294967297 M-x recenter" was treated as if
163 it were "C-u 1 M-x recenter" on a typical 64-bit host.
164
165 * xdisp.c (try_window_id): Check Emacs fixnum range before
166 converting to 'int'.
167
168 * window.c (window_scroll_line_based, Frecenter):
169 Check that an Emacs fixnum is in range before assigning it to 'int'.
170 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
171 values converted from Emacs fixnums.
172 (Frecenter): Don't wrap around a line count if it is out of 'int'
173 range; instead, treat it as an extreme value.
174 (Fset_window_configuration, compare_window_configurations):
175 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
176
177 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
178 that can exceed INT_MAX. Check that EMACS_INT value is in range
179 before assigning it to the (possibly-narrower) index.
180 (match_limit): Don't assume that a fixnum can fit in 'int'.
181
182 * print.c (print_object): Use ptrdiff_t, not int, for index that can
183 exceed INT_MAX.
184
185 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
186 (Fvertical_motion): Don't wrap around LINES values that don't fit
187 in 'int'. Instead, treat them as extreme values. This is good
188 enough for windows, which can't have more than INT_MAX lines anyway.
189
190 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
191
192 * Require libxml/parser.h to avoid compilation warning.
193
194 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
195
196 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
197 since this reportedly can destroy thread storage.
198
199 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
200
201 * syntax.c (find_defun_start): Update all cache variables if
202 exiting early (Bug#9401).
203
204 2011-08-30 Eli Zaretskii <eliz@gnu.org>
205
206 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
207
208 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
209 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
210 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
211
212 * term.c (tty_append_glyph): New function.
213 (produce_stretch_glyph): Static function and its prototype deleted.
214
215 * dispextern.h (produce_stretch_glyph, tty_append_glyph): Add
216 prototypes.
217
218 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
219
220 * image.c (parse_image_spec): Check for nonnegative, not for positive,
221 when checking :margin (Bug#9390).
222 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
223 Renamed from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
224 so that the name doesn't mislead. All uses changed.
225
226 2011-08-28 Johan Bockgård <bojohan@gnu.org>
227
228 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
229 set_tty_hooks.
230
231 2011-08-27 Eli Zaretskii <eliz@gnu.org>
232
233 * xdisp.c (move_it_to): Don't bail out early when reaching
234 position beyond to_charpos, if we are scanning backwards.
235 (move_it_vertically_backward): When DY == 0, make sure we get to
236 the first character in the line after the newline.
237
238 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
239
240 * ccl.c: Improve and simplify overflow checking (Bug#9196).
241 (ccl_driver): Do not generate an out-of-range pointer.
242 (Fccl_execute_on_string): Remove unnecessary check for
243 integer overflow, noted by Stefan Monnier in
244 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
245 Remove a FIXME that didn't need fixing.
246 Simplify the newly-introduced buffer reallocation code.
247
248 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
249
250 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
251
252 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
253
254 Integer and memory overflow issues (Bug#9196).
255
256 * doc.c (get_doc_string): Rework so that
257 get_doc_string_buffer_size is the actual buffer size, rather than
258 being 1 less than the actual buffer size; this makes xpalloc more
259 convenient.
260
261 * image.c (x_allocate_bitmap_record, cache_image):
262 * xselect.c (Fx_register_dnd_atom):
263 Simplify previous changes by using xpalloc.
264
265 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
266 since either will do and ptrdiff_t is convenient with xpalloc.
267
268 * charset.c (charset_table_size)
269 (struct charset_sort_data.priority): Now ptrdiff_t.
270 (charset_compare): Don't overflow if priorities differ greatly.
271 (Fsort_charsets): Don't assume list length fits in int.
272 Check for size-calculation overflow when allocating sort data.
273 (syms_of_charset): Allocate an initial charset table that is
274 just under 64 KiB, to avoid problems with glibc malloc and mmap.
275
276 * cmds.c (internal_self_insert): Check for size-calculation overflow.
277
278 * composite.h (struct composition.glyph_len): Now int, not unsigned.
279 The actual value is always <= INT_MAX, and leaving it unsigned made
280 overflow checking harder.
281
282 * dispextern.h (struct glyph_matrix.rows_allocated)
283 (struct face_cache.size): Now ptrdiff_t, for convenience in use
284 with xpalloc. The values are still always <= INT_MAX.
285
286 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
287
288 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
289 (SAFE_NALLOCA): New macro.
290
291 * region-cache.c (struct boundary.pos, find_cache_boundary)
292 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
293 (set_cache_region, invalidate_region_cache)
294 (revalidate_region_cache, know_region_cache, region_cache_forward)
295 (region_cache_backward, pp_cache):
296 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
297 so that ptrdiff_t * can be passed to xpalloc.
298 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
299 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
300 (pp_cache): Don't assume cache_len fits in int.
301 * region-cache.h: Adjust extern decls to match.
302
303 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
304 EMACS_INT, since either will do, for xpalloc.
305
306 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
307 (xnmalloc, xnrealloc, xpalloc): New functions.
308
309 * bidi.c (bidi_shelve_header_size): New constant.
310 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
311 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
312
313 * bidi.c (bidi_cache_shrink):
314 * buffer.c (overlays_at, overlays_in, record_overlay_string)
315 (overlay_strings):
316 Don't update size of array until after memory allocation succeeds,
317 because xmalloc/xrealloc may not return.
318 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
319 now that we have proper integer overflow checking.
320 (record_overlay_string, overlay_strings): Catch overflows when
321 calculating size of overlay_str_buf.
322
323 * callproc.c (Fcall_process): Check for size overflow when
324 calculating size of args2.
325 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
326 Normally we prefer signed values, but sticking with ptrdiff_t would
327 require adding more-complicated checks.
328
329 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
330 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
331 Redo buffer-overflow calculations to avoid integer overflow.
332 Add a FIXME comment where memory seems to be over-allocated.
333
334 * character.c (Fstring): Check for size-calculation overflow.
335
336 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
337 unnecessary integer overflow. Check for size overflow.
338 (encode_coding_object): Don't update size until xmalloc succeeds.
339
340 * composite.c (get_composition_id): Check for overflow in glyph
341 length calculations.
342
343 Integer and memory overflow fixes for display code.
344 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
345 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
346 (scrolling_window): Check for overflow in size calculations.
347 (line_draw_cost, realloc_glyph_pool, add_row_entry):
348 Don't assume glyph table len fits in int.
349 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
350 (row_table_size): Now ptrdiff_t, not int.
351 (scrolling_window): Avoid overflow in size calculations.
352 Don't update size until allocation succeeds.
353 * fns.c (concat): Check for overflow in size calculations.
354 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
355 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
356 (NEXT_ALMOST_PRIME_LIMIT): New constant.
357
358 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
359 (get_doc_string): Check for size calculation overflow.
360 Don't update size until allocation succeeds.
361 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
362 EMACS_INT, where ptrdiff_t will do.
363 (Fsubstitute_command_keys): Check for string overflow.
364
365 * editfns.c (set_time_zone_rule): Don't assume environment length
366 fits in int.
367 (message_length): Now ptrdiff_t, not int.
368 (Fmessage_box): Don't update size until allocation succeeds.
369 Don't assume message length fits in int.
370 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
371
372 * emacs.c (main): Do not reallocate argv, since there is a null at
373 the end that can be overwritten, and this way there's no need to
374 worry about size-calculation overflow.
375 (sort_args): Check for size-calculation overflow.
376
377 * eval.c (init_eval_once, grow_specpdl): Don't update size until
378 alloc succeeds.
379 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
380
381 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
382 (x_set_scroll_bar_width, x_figure_window_size):
383 Check for integer overflow.
384 (x_set_alpha): Do not assume XINT fits in int.
385
386 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
387 This is for the members text_lines, text_cols, total_lines, total_cols,
388 where the system imposes an 'int' limit.
389
390 * fringe.c (Fdefine_fringe_bitmap):
391 Don't update size until alloc works.
392
393 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
394 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
395
396 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
397 Check for size-calculation overflow.
398 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
399 do, as we prefer signed integers.
400 (id_to_widget.max_size, id_to_widget.used)
401 (xg_store_widget_in_map, xg_remove_widget_from_map)
402 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
403 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
404 Use and return ptrdiff_t, not int.
405 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
406 * gtkutil.h: Change prototypes to match the above.
407
408 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
409 are duplicate now that they've been promoted to lisp.h.
410 (x_allocate_bitmap_record, x_alloc_image_color)
411 (make_image_cache, cache_image, xpm_load):
412 Don't update size until alloc is done.
413 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
414 (x_detect_edges):
415 Check for size calculation overflow.
416 (ct_colors_allocated_max): New constant.
417 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
418 overflow.
419
420 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
421 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
422 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
423 Use ptrdiff_t, not int, to count maps.
424 (read_char_minibuf_menu_prompt): Check for overflow in size
425 calculations. Don't update size until allocation succeeds. Redo
426 calculations to avoid overflow.
427 * keyboard.h: Change prototypes to match the above.
428
429 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
430 to count maps.
431 (current_minor_maps): Check for size calculation overflow.
432 * keymap.h: Change prototypes to match the above.
433
434 * lread.c (read1, init_obarray): Don't update size until alloc done.
435
436 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
437 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
438
439 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
440 Now ptrdiff_t, not int.
441 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
442 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
443
444 * process.c (Fnetwork_interface_list): Check for overflow
445 in size calculation.
446
447 * region-cache.c (move_cache_gap): Check for size calculation overflow.
448
449 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
450 overflow. Don't bother calling xmalloc when xrealloc will do.
451
452 * search.c (Freplace_match): Check for size calculation overflow.
453 (Fset_match_data): Don't assume list lengths fit in 'int'.
454
455 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
456 for command line length. Do not attempt to address one before the
457 beginning of an array, as that's not portable.
458
459 * term.c (max_frame_lines): Remove; unused.
460 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
461 not int.
462 (encode_terminal_code, calculate_costs): Check for size
463 calculation overflow.
464 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
465 table lengths and related sizes. Don't update size until alloc
466 done. Redo calculations to avoid overflow.
467 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
468
469 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
470 subtracting pointers.

472 until alloc done.
473
474 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
475 Don't update size until alloc done.
476 Redo size calculations to avoid overflow.

485 Use ptrdiff_t, not int, for sizes.
486 (Finternal_make_lisp_face, cache_face):
487 Check for size calculation overflow.
488 (cache_face): Treat size calculation overflows as if they were
489 memory exhaustion (the usual treatment), rather than aborting.
490
491 * xfns.c (x_encode_text, x_set_name_internal)
492 (Fx_change_window_property): Use ptrdiff_t, not int, to count
493 sizes, since they can exceed INT_MAX in size. Check for size
494 calculation overflow.
495
496 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
497 (xg_select): Check for size calculation overflow.
498 Don't update size until alloc done.
499
500 * xrdb.c (get_environ_db): Don't assume path length fits in int,
501 as sprintf is limited to int lengths.
502
503 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
504 (X_LONG_MIN): New macros.
505 Use them to make the following changes clearer.
506 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
507 This change doesn't affect the value now, but it may help remind
508 future maintainers not to raise the value too much later.
509 (SELECTION_QUANTUM): Remove, replacing with ...
510 (selection_quantum): ... new function, which avoids overflow.
511 All uses changed.
512 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
513 assumption that selection length fits in 'int'.
514 (x_reply_selection_request, x_handle_selection_request)
515 (x_get_window_property, receive_incremental_selection)
516 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
517 (lisp_data_to_selection_data, clean_local_selection_data):

520 (receive_incremental_selection, x_property_data_to_lisp):
521 Redo calculations to avoid overflow.
522 (x_reply_selection_request): When sending hint, ceiling it at
523 X_LONG_MAX rather than relying on wraparound overflow to send
524 something.
525 (x_get_window_property, receive_incremental_selection)
526 (lisp_data_to_selection_data, x_property_data_to_lisp):
527 Check for size-calculation overflow.
528 (x_get_window_property, receive_incremental_selection)
529 (lisp_data_to_selection_data, Fx_register_dnd_atom):
530 Don't store size until memory allocation succeeds.
531 (x_get_window_property): Plug memory leak on memory exhaustion.
532 Don't double-block input; malloc is safe here. Don't assume 2**34
533 - 4 fits in unsigned long. Add an xassert to check
534 XGetWindowProperty overflow. Be more careful about overflow
535 calculations, and distinguish size from memory overflow better.
536 (receive_incremental_selection): When tracing, don't assume
537 unsigned int is less than INT_MAX.
538 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
539 harmful) conversions of unsigned short to int.
540 (lisp_data_to_selection_data): Don't assume that integers
541 in the range -65535 through -1 fit in an X unsigned short.
542 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
543 result parameters unless successful. Rely on cons_to_unsigned
544 to report problems with elements; the old code wasn't right anyway.
545 (x_check_property_data): Check for int overflow; we cannot use
546 a wider type due to X limits.
547 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
548
549 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
550
551 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
552 (x_term_init): Check for size calculation overflow.
553 (x_color_cells): Don't store size until memory allocation succeeds.
554 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
555 Don't assume alloca size is less than MAX_ALLOCA.
556 (x_term_init): Don't assume length fits in int (sprintf is limited
557 to int size).
558
559 Use ptrdiff_t for composition IDs.
560 * character.c (lisp_string_width):
561 * composite.c (composition_table_size, n_compositions)
562 (get_composition_id, composition_gstring_from_id):

578 * image.c (xpm_get_color_table_h):
579 * lisp.h (hash_lookup, hash_put):
580 * minibuf.c (Ftest_completion):
581 Use ptrdiff_t for hash table indexes, not int (which is too
582 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
583 32-bit --with-wide-int hosts).
584
585 * charset.c (Fdefine_charset_internal): Check for integer overflow.
586 Add a FIXME comment about memory leaks.
587 (syms_of_charset): Don't assume xmalloc returns.
588
589 Don't assume that stated character widths fit in int.
590 * character.c (Fchar_width, c_string_width, lisp_string_width):
591 * character.h (CHAR_WIDTH):
592 * indent.c (MULTIBYTE_BYTES_WIDTH):
593 Use sanitize_char_width to avoid undefined and/or bad behavior
594 with outlandish widths.
595 * character.h (sanitize_tab_width): Renamed from sanitize_width,
596 now that we have two such functions. All uses changed.
597 (sanitize_char_width): New inline function.
598
599 Don't assume that tab-width fits in int.
600 * character.h (sanitize_width): New inline function.
601 (SANE_TAB_WIDTH): New macro.

606
607 * fileio.c: Integer overflow issues with file modes.
608 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
609
610 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
611 Remove unreachable code.
612 (read_hex, load_charset_map_from_file): Check for integer overflow.
613
614 * xterm.c: don't go over XClientMessageEvent limit
615 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
616 (x_send_scroll_bar_event): Likewise. Check that the size does not
617 exceed limits imposed by XClientMessageEvent, as well as the usual
618 ptrdiff_t and size_t limits.
619
620 * keyboard.c: Overflow, signedness and related fixes.
621 (make_lispy_movement): Use same integer type in forward decl
622 that is used in the definition.
623 (read_key_sequence, keyremap_step):
624 Change bufsize argument back to int, undoing my 2011-03-30 change.
625 We prefer signed types, and int is wide enough here.
626 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
627 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
628 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
629 length, not size_t. Use ptrdiff_t for index, not int.
630 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
631 possibility of integer overflow.
632
633 Overflow, signedness and related fixes for images.

642 * nsmenu.m (update_frame_tool_bar):
643 * xdisp.c (calc_pixel_width_or_height):
644 * xfns.c (image_cache_refcount):
645 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
646 on typical 64-bit hosts.
647
648 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
649 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

654 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
655 (lookup_image): Remove unnecessary tests.
656 (xbm_image_p): Locals are now of int, not EMACS_INT,
657 since parse_image_check makes sure they fit into int.
658 (png_load, gif_load, svg_load_image):
659 Prefer int to unsigned where either will do.
660 (tiff_handler): New function, combining the cores of the
661 old tiff_error_handler and tiff_warning_handler. This
662 function is rewritten to use vsnprintf and thereby avoid
663 stack buffer overflows. It uses only the features of vsnprintf
664 that are common to both POSIX and native Microsoft.
665 (tiff_error_handler, tiff_warning_handler): Use it.
666 (tiff_load, gif_load, imagemagick_load_image):
667 Don't assume :index value fits in 'int'.
668 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
669 (imagemagick_load_image): Check that crop parameters fit into
670 the integer types that MagickCropImage accepts. Don't assume
671 Vimagemagick_render_type has a nonnegative value. Don't assume
672 size_t fits in 'long'.
673 (gs_load): Use printmax_t to print the widest integers possible.
674 Check for integer overflow when computing image height and width.
675
676 2011-08-26 Eli Zaretskii <eliz@gnu.org>
677

679 will be invisible in the resulting window. (Bug#9324)
680
681 2011-08-25 Eli Zaretskii <eliz@gnu.org>
682
683 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
684 the display spec is of the form `(space ...)'.
685 (handle_display_spec): Return the value returned by
686 handle_single_display_spec, not just 1 or zero.
687 (handle_single_display_spec): If the display spec is of the form
688 `(space ...)', and specifies display in the text area, return 2
689 rather than 1.
690 (try_cursor_movement): Check for the need to scroll more
691 accurately, and prefer exact match for point under bidi. Don't
692 advance `row' beyond the last row of the window.
693
694 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
695 into disp_prop; all users changed.
696
697 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
698 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
699 for the text covered by the display property.

708
709 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
710 buffers, return left-to-right.
711 (set_cursor_from_row): Consider candidate row a win if its glyph
712 represents a newline and point is on that newline. Fixes cursor
713 positioning on the newline at EOL of R2L text within L2R
714 paragraph, and vice versa.
715 (try_cursor_movement): Check continued rows, in addition to
716 continuation rows. Fixes unwarranted scroll when point enters a
717 continued line of R2L text within an L2R paragraph, or vice versa.
718 (cursor_row_p): Consider the case of point being equal to
719 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
720 from the end of a short line to the beginning of a continued line
721 of R2L text within L2R paragraph.
722 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

744
745 * xdisp.c (redisplay_window): When computing centering_position,
746 account for the height of the header line. (Bug#8874)
747
748 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
749 instead of CHAR_TO_BYTE. Fixes a crash when a completion
750 candidate is selected by the mouse, and that candidate has a
751 composed character under the mouse.
752
753 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
754 coordinates reported by pos-visible-in-window-p for a composed

763 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
764 consider it a hit if to_charpos is anywhere in the range of the
765 composed buffer positions.
766
767 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
768
769 * image.c (gif_load): Don't assume that each subimage has the same
770 dimensions as the base image. Handle disposal method that is
771 "undefined" by the gif spec (Bug#9335).
772
773 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
774

779
780 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
781 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
782 from an Org mode buffer to a Speedbar frame.
783
784 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
785 a composition, take its buffer position from IT->cmp_it.charpos.
786 Fixes cursor positioning at the beginning of a line that begins
787 with a composed character.
788
789 2011-08-18 Eli Zaretskii <eliz@gnu.org>
790
791 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
792 character bidirectional type, use STRONG_L instead. Fixes crashes
793 in a buffer produced by `describe-categories'.
794
795 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
796 members before the level stack, so they would be saved and
797 restored when copying iterator state. Fixes incorrect reordering
798 around TABs covered by display properties.
799
800 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
801
802 * process.c (Fnetwork_interface_list): Correctly determine buffer

893
894 * nsterm.m (sendEvent): If event is NSApplicationDefined and
895 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
896 the event loop (Bug#7276).
897
898 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
899
900 * gnutls.c (QCgnutls_bootprop_priority)
901 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
902 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
903 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
904 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
905 (QCgnutls_bootprop_verify_hostname_error)
906 (QCgnutls_bootprop_callbacks_verify): Rename from
907 Qgnutls_bootprop_..., all uses changed.
908
909 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
910 uses changed.
911
912 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
913
914 * xfaces.c (Qframe_set_background_mode): Now static.
915 * dispextern.h (Qframe_set_background_mode): Remove decl.
916
917 * process.c (Fnetwork_interface_info): Declare local only if needed.
918
919 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
920
921 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
922 (Fnetwork_interface_list): Allocate in increments of bytes instead
923 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
924 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
925 sockaddr.
926 (struct ifflag_def): notrailers is smart on OSX.
927 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
928 Get hardware address with getifaddrs if available.
929
930 2011-08-12 Eli Zaretskii <eliz@gnu.org>
931
932 * xdisp.c (iterate_out_of_display_property): xassert that
933 IT->position is set to within IT->object's boundaries. Break from
934 the loop as soon as EOB is reached; avoids infloops in redisplay
935 when IT->position is set up wrongly due to some bug.
936 Set IT->current to match the bidi iterator unconditionally.
937 (push_display_prop): Allow GET_FROM_STRING as IT->method on
938 entry. Force push_it to save on the stack the current
939 buffer/string position, to be restored by pop_it. Fix flags in
940 the iterator structure wrt the object coming from a display
941 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
942 properties. (Bug#9284)
943
944 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
945
946 * fontset.c (fontset_get_font_group): Add proper type checks.
947 (Bug#9172)
948
949 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
950
951 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
952 and LC_VERSION_MIN_MACOSX.
953 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
954 (dump_it) [LC_FUNCTION_STARTS]: Use it.
955
956 2011-08-08 Eli Zaretskii <eliz@gnu.org>
957
958 * xdisp.c (forward_to_next_line_start): Allow to use the
959 no-display-properties-and-no-overlays under bidi display.
960 Set disp_pos in the bidi iterator to avoid searches for display
961 properties and overlays.
962
963 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
964
965 * editfns.c (Fset_time_zone_rule): Document relationship with the
966 setenv function.
967
968 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
969 the font entity extracted from the cache (Bug#8109).
970
971 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
972
973 * composite.c (autocmp_chars): Don't reset point. That is done by
974 restore_point_unwind (Bug#5984).
975
976 2011-08-07 Juri Linkov <juri@jurta.org>
977
978 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
979 to show the arg `TIME' instead of `TIMEVAL'.
980
981 2011-08-06 Eli Zaretskii <eliz@gnu.org>
982
983 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
984 display property strides EOL and includes a newline, as in
985 longlines-mode. (Bug#9254)
986 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
987 word-wrap under bidirectional display. (Bug#9224)
988
989 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
990 is non-zero, even if the data buffer is NULL. Fixes a crash in
991 vertical-motion with longlines-mode. (Bug#9254)
992
993 2011-08-05 Eli Zaretskii <eliz@gnu.org>
994
995 * bidi.c <bidi_cache_total_alloc>: Now static.
996 (bidi_initialize): Initialize bidi_cache_total_alloc.
997
998 * xdisp.c (display_line): Release buffer allocated for shelved bidi
999 cache. (Bug#9221)
1000
1001 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
1002 amount allocated this far in `bidi_cache_total_alloc'.
1003 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
1004 non-zero, only free the data buffer without restoring the cache
1005 contents. All callers changed.
1006
1007 * dispextern.h (bidi_unshelve_cache): Update prototype.
1008
1009 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
1010 (move_it_in_display_line, move_it_to)
1011 (move_it_vertically_backward, move_it_by_lines): Replace the call
1012 to xfree to an equivalent call to bidi_unshelve_cache.
1013 (move_it_in_display_line_to): Fix logic of returning
1014 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
1015
1016 2011-08-05 Eli Zaretskii <eliz@gnu.org>
1017
1018 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
1019 came from a string character with a `cursor' property. (Bug#9229)
1020
1021 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
1022
1023 * Makefile.in (LIB_PTHREAD): New variable.
1024 (LIBES): Add LIB_PTHREAD (Bug#9216).
1025
1026 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
1027 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
1028
1029 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
1030
1031 * regex.c (re_iswctype): Remove some redundant boolean
1032 conversions.
1033
1034 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
1035
1036 * xterm.c (x_find_topmost_parent): New function.
1037 (x_set_frame_alpha): Find topmost parent window with
1038 x_find_topmost_parent and set the property there also (bug#9181).
1039 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
1040
1041 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
1042
1043 * callproc.c (Fcall_process): Avoid vfork clobbering
1044 the local vars buffer, coding_systems, current_dir.
1045
1046 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
1047
1048 * keymap.c (Fmake_composed_keymap): Move to subr.el.
1049
1050 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
1051
1052 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
1053 so that it is not optimized away.
1054
1055 * xdisp.c (compute_display_string_pos): Remove unused local.
1056
1057 2011-08-02 Eli Zaretskii <eliz@gnu.org>
1058
1059 Fix slow cursor motion and scrolling in large buffers with
1060 selective display, like Org Mode buffers. (Bug#9218)
1061
1062 * dispextern.h (struct bidi_it): New member disp_prop_p.
1063
1064 * xdisp.c: Remove one-slot cache of display string positions.
1065 (compute_display_string_pos): Accept an additional argument
1066 DISP_PROP_P; callers changed. Scan at most 5K characters forward
1067 for a display string or property. If found, set DISP_PROP_P
1068 non-zero.
1069
1070 * bidi.c (bidi_fetch_char): Accept an additional argument
1071 DISP_PROP_P, and pass it to compute_display_string_pos.
1072 Only handle text covered by a display string if DISP_PROP_P is returned
1073 non-zero. All callers of bidi_fetch_char changed.
1074
1075 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
1076
1077 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
1078
1079 2010-12-03 Don March <don@ohspite.net>
1080
1081 * keymap.c (Fdefine_key): Fix non-prefix key error message when
1082 last character M-[char] is translated to ESC [char] (bug#7541).
1083
1084 2011-08-02 Kenichi Handa <handa@m17n.org>
1085
1086 * lisp.h (uniprop_table): Extern it.
1087
1088 * chartab.c (uniprop_table): Make it non-static.
1089
1090 2011-08-01 Eli Zaretskii <eliz@gnu.org>
1091
1092 * xdisp.c (forward_to_next_line_start): Accept additional argument
1093 BIDI_IT_PREV, and store into it the state of the bidi iterator had
1094 on the newline.
1095 (reseat_at_next_visible_line_start): Use the bidi iterator state
1096 returned by forward_to_next_line_start to restore the state of
1097 it->bidi_it after backing up to previous newline. (Bug#9212)
1098
1099 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
1100
1101 * regex.c (re_comp): Protoize.
1102 (re_exec): Fix return type.
1103 (regexec): Fix type of `ret'. (Bug#9203)
1104
1105 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
1106
1107 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
1108 This is needed if max-image-size is a floating-point number.
1109
1110 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
1111
1112 * print.c (print_object): Print empty symbol as ##.
1113
1114 * lread.c (read1): Read ## as empty symbol.
1115
1116 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
1117
1118 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
1119 setting frame foreground color (Bug#9175).
1120 (x_set_background_color): Likewise.
1121
1122 * nsmenu.m (-setText): Size tooltip dimensions precisely to
1123 contents (Bug#9176).
1124 (EmacsTooltip -init): Remove bezels and add shadows to
1125 tooltip windows.
1126
1127 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
1128 or scroll bar (Bug#8470).
1129
1130 * nsfont.m (nsfont_open): Remove assignment to voffset and
1131 unnecessary vars hshink, expand, hd, full_height, min_height.
1132 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
1133
1134 * nsterm.h (nsfont_info): Remove voffset field.
1135
1136 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
1137
1138 Implement strike-through and overline on NextStep (Bug#8863).
1139
1140 * nsfont.m (nsfont_open): Use underline position provided by font,
1141 instead of hard-coded value of 2.
1142 (nsfont_draw): Call ns_draw_text_decoration instead.
1143
1144 * nsterm.h: Add declaration for ns_draw_text_decoration.
1145
1146 * nsterm.m (ns_draw_text_decoration): New function for drawing
1147 underline, overline, and strike-through.
1148 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
1149 ns_draw_text_decoration. Change treatment of cursor drawing to
1150 accomodate underlining, etc.
1151
1152 2011-07-28 Eli Zaretskii <eliz@gnu.org>
1153
1154 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
1155 default.
1156
1157 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
1158
1159 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
1160 Without this fix, if a signal arrives just after memory fills up,
1161 'malloc' might be invoked reentrantly.
1162
1163 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
1164 In other words, assume that every image size is allowed, on non-X
1165 hosts. This assumption is probably wrong, but it lets Emacs compile.
1166
1167 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
1168
1169 * regex.c (re_iswctype): Convert return values to boolean.
1170
1171 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
1172
1173 * xdisp.c (compute_display_string_pos): Don't use cached display
1174 string position if the buffer had its restriction changed.
1175 (Bug#9184)
1176
1177 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
1178
1179 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
1180
1181 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
1182
1183 Integer signedness and overflow and related fixes. (Bug#9079)
1184
1185 * bidi.c: Integer size and overflow fixes.
1186 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
1187 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
1188 (bidi_cache_find_level_change, bidi_cache_ensure_space)
1189 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
1190 (bidi_find_other_level_edge):
1191 Use ptrdiff_t instead of EMACS_INT where either will do.
1192 This works better on 32-bit hosts configured --with-wide-int.
1193 (bidi_cache_ensure_space): Check for size-calculation overflow.
1194 Use % rather than repeated addition, for better worst-case speed.
1195 Don't set bidi_cache_size until after xrealloc returns, because it
1196 might not return.
1197 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
1198 (bidi_cache_ensure_space): Also check that the bidi cache size
1199 does not exceed that of the largest Lisp string or buffer. See Eli
1200 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
1201
1202 * alloc.c (__malloc_size_t): Remove.
1203 All uses replaced by size_t. See Andreas Schwab's note
1204 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
1205
1206 * image.c: Improve checking for integer overflow.
1207 (check_image_size): Assume that f is nonnull, since
1208 it is always nonnull in practice. This is one less thing to
1209 worry about when checking for integer overflow later.
1210 (x_check_image_size): New function, which checks for integer
1211 overflow issues inside X.
1212 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
1213 This removes the need for a memory_full check.
1214 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
1215 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
1216 (xbm_read_bitmap_data): Change locals back to 'int', since
1217 their values must fit in 'int'.
1218 (xpm_load_image, png_load, tiff_load):
1219 Invoke x_create_x_image_and_pixmap earlier,
1220 to avoid much needless work if the image is too large.
1221 (tiff_load): Treat overly large images as if
1222 x_create_x_image_and_pixmap failed, not as malloc failures.
1223 (gs_load): Use x_check_image_size.
1224
1225 * gtkutil.c: Omit integer casts.
1226 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
1227 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
1228
1229 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
1230
1231 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
1232 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
1233 would wrongly return t on a 64-bit host.
1234
1235 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
1236 The plain *_OVERFLOW macros run afoul of GCC bug 49705
1237 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
1238 and therefore cause GCC to emit a bogus diagnostic in some cases.
1239
1240 * image.c: Integer signedness and overflow and related fixes.
1241 This is not an exhaustive set of fixes, but it's time to
1242 record what I've got.
1243 (lookup_pixel_color, check_image_size): Remove redundant decls.
1244 (check_image_size): Don't assume that arbitrary EMACS_INT values
1245 fit in 'int', or that arbitrary 'double' values fit in 'int'.
1246 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
1247 (tiff_load, imagemagick_load_image):
1248 Check for overflow in size calculations.
1249 (x_create_x_image_and_pixmap): Remove unnecessary test for
1250 xmalloc returning NULL; that can't happen.
1251 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
1252 (xpm_color_bucket): Use better integer hashing function.
1253 (xpm_cache_color): Don't possibly over-allocate memory.
1254 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
1255 (gif_memory_source):
1256 Use ptrdiff_t, not int or size_t, to record sizes.
1257 (png_load): Don't assume values greater than 2**31 fit in 'int'.
1258 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
1259 either works, as we prefer signed integers.
1260 (tiff_read_from_memory, tiff_write_from_memory):
1261 Return tsize_t, not size_t, since that's what the TIFF API wants.
1262 (tiff_read_from_memory): Don't fail simply because the read would
1263 go past EOF; instead, return a short read.
1264 (tiff_load): Omit no-longer-needed casts.
1265 (Fimagemagick_types): Don't assume size fits into 'int'.
1266
1267 Improve hashing quality when configured --with-wide-int.
1268 * fns.c (hash_string): New function, taken from sxhash_string.
1269 Do not discard information about ASCII character case; this
1270 discarding is no longer needed.
1271 (sxhash-string): Use it. Change sig to match it. Caller changed.
1272 * lisp.h: Declare it.
1273 * lread.c (hash_string): Remove, since we now use fns.c's version.
1274 The fns.c version returns a wider integer if --with-wide-int is
1275 specified, so this should help the quality of the hashing a bit.
1276
1277 * emacs.c: Integer overflow minor fix.
1278 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
1279 Define only if GNU_LINUX.
1280 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
1281
1282 * dispnew.c: Integer signedness and overflow fixes.
1283 Remove unnecessary forward decls, that were a maintenance hassle.
1284 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
1285 All uses changed.
1286 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
1287 (scrolling_window): Use ptrdiff_t, not int, for byte count.
1288 (prepare_desired_row, line_draw_cost):
1289 Use int, not unsigned, where either works.
1290 (save_current_matrix, restore_current_matrix):
1291 Use ptrdiff_t, not size_t, where either works.
1292 (init_display): Check for overflow more accurately, and without
1293 relying on undefined behavior.
1294
1295 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
1296 Remove, replacing with the new symbols in lisp.h. All uses changed.
1297 * fileio.c (make_temp_name):
1298 * filelock.c (lock_file_1, lock_file):
1299 * xdisp.c (message_dolog):
1300 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
1301 Use pMd etc. instead.
1302 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
1303 replacing the pWIDE etc. symbols removed from editfns.c.
1304
1305 * keyboard.h (num_input_events): Now uintmax_t.
1306 This is (very slightly) less likely to mess up due to wraparound.
1307 All uses changed.
1308
1309 * buffer.c: Integer signedness fixes.
1310 (alloc_buffer_text, enlarge_buffer_text):
1311 Use ptrdiff_t rather than size_t when either will do, as we prefer
1312 signed integers.
1313
1314 * alloc.c: Integer signedness and overflow fixes.
1315 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
1316 (__malloc_size_t): Default to size_t, not to int.
1317 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
1318 (Fgarbage_collect, mark_object_loop_halt, mark_object):
1319 Prefer ptrdiff_t to size_t when either would do, as we prefer
1320 signed integers.
1321 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
1322 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
1323 Now const. Initialize with values that are in range even if char
1324 is signed.
1325 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
1326 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
1327 These functions do the right thing with sizes > 2**32.
1328 (check_depth): Now ptrdiff_t, not int.
1329 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
1330 Adjust to new way of storing sizes. Check for size overflow bugs
1331 in rest of code.
1332 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
1333 slightly wrong anyway, as it missed one instance of
1334 XMALLOC_OVERRUN_CHECK_OVERHEAD.
1335 (refill_memory_reserve): Omit needless cast to size_t.
1336 (mark_object_loop_halt): Mark as externally visible.
1337
1338 * xselect.c: Integer signedness and overflow fixes.
1339 (Fx_register_dnd_atom, x_handle_dnd_message):
1340 Use ptrdiff_t, not size_t, since we prefer signed.
1341 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
1342 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
1343 x_dnd_atoms_size and x_dnd_atoms_length.
1344
1345 * doprnt.c: Prefer signed to unsigned when either works.
1346 * eval.c (verror):
1347 * doprnt.c (doprnt):
1348 * lisp.h (doprnt):
1349 * xdisp.c (vmessage):
1350 Use ptrdiff_t, not size_t, when using or implementing doprnt,
1351 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
1352 prefer signed arithmetic to avoid comparison confusion.
1353 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
1354 but is a bit tricky.
1355
1356 Assume freestanding C89 headers, string.h, stdlib.h.
1357 * data.c, doprnt.c, floatfns.c, print.c:
1358 Include float.h unconditionally.
1359 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
1360 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
1361 * regex.c: Likewise for stddef.h, string.h.
1362 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
1363 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
1364 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
1365 (STDC_HEADERS): Remove obsolete defines.
1366 * sysdep.c: Include limits.h unconditionally.
1367
1368 Assume support for memcmp, memcpy, memmove, memset.
1369 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
1370 * regex.c (memcmp, memcpy):
1371 Remove; we assume C89 now.
1372
1373 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
1374 (__malloc_safe_bcopy): Remove; no longer needed.
1375
1376 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
1377 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
1378 well either way, and we prefer signed to unsigned.
1379
1380 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
1381
1382 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
1383 closes the connection while we're reading (bug#9182).
1384
1385 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
1386
1387 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
1388 are specified (Bug#9168).
1389
1390 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
1391
1392 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
1393 Found by GCC static checking and --with-wide-int on a 32-bit host.
1394
1395 2011-07-25 Eli Zaretskii <eliz@gnu.org>
1396
1397 * xdisp.c (compute_display_string_pos): Fix logic of caching
1398 previous display string position. Initialize cached_prev_pos to
1399 -1. Fixes slow-down at the beginning of a buffer.
1400
1401 2011-07-24 Eli Zaretskii <eliz@gnu.org>
1402
1403 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
1404 for attrs[LFACE_FONTSET_INDEX].
1405
1406 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
1407
1408 * xml.c (parse_region): Remove unused local
1409 that was recently introduced.
1410
1411 2011-07-23 Eli Zaretskii <eliz@gnu.org>
1412
1413 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
1414 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
1415
1416 * xdisp.c (move_it_in_display_line_to): Record the best matching
1417 position for TO_CHARPOS while scanning the line, and restore it on
1418 exit if none of the characters scanned was an exact match.
1419 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
1420 when exact match is impossible due to invisible text, and the
1421 lines are truncated.
1422
1423 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
1424
1425 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
1426 for OSX >= 10.7.
1427
1428 2011-07-22 Eli Zaretskii <eliz@gnu.org>
1429
1430 Fix a significant slow-down of cursor motion with C-n, C-p,
1431 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
1432 auto-repeat under bidi redisplay in fontified buffers.
1433 * xdisp.c (compute_stop_pos_backwards): New function.
1434 (next_element_from_buffer): Call compute_stop_pos_backwards to
1435 find a suitable prev_stop when we find ourselves before
1436 base_level_stop.
1437 (reseat): Don't look for prev_stop, as that could mean a very long
1438 run.
1439 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
1440 <cached_disp_overlay_modiff>: Cache for last found display string
1441 position.
1442 (compute_display_string_pos): Return the cached position if asked
1443 about the same buffer in the same area of character positions, and
1444 the buffer wasn't changed since the time the display string
1445 position was cached.
1446
1447 2011-07-22 Eli Zaretskii <eliz@gnu.org>
1448
1449 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
1450 is an integer, which is important for empty lines. (Bug#9149)
1451
1452 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
1453
1454 * frame.c (Fmodify_frame_parameters): In tty case, update the
1455 default face if necessary (Bug#4238).
1456
1457 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
1458
1459 * editfns.c (Fstring_to_char): No need to explain what a character
1460 is in the docstring (Bug#6576).
1461
1462 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
1463
1464 * xml.c (parse_region): Make sure we always return a tree.
1465
1466 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
1467
1468 * xml.c (parse_region): If a document contains only comments,
1469 return that, too.
1470
1471 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
1472
1473 * xml.c (make_dom): Return comments, too.
1474
1475 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
1476
1477 Port to OpenBSD.
1478 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
1479 and the surrounding thread.
1480 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
1481 rather than fgets, and retry after EINTR. Otherwise, 'emacs
1482 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
1483 timer goes off.
1484 * s/openbsd.h (BROKEN_SIGIO): Define.
1485 * unexelf.c (unexec) [__OpenBSD__]:
1486 Don't update the .mdebug section of the Alpha COFF symbol table.
1487
1488 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
1489
1490 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
1491 (bug#8460).
1492
1493 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
1494
1495 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
1496 This fixes some race conditions on the permissions of any newly
1497 created file.
1498
1499 * alloc.c (valid_pointer_p): Use pipe, not open.
1500 This fixes some permissions issues when debugging.
1501
1502 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
1503 If fchown fails to set both uid and gid, try to set just gid,
1504 as that is sometimes allowed. Adjust the file's mode to eliminate
1505 setuid or setgid bits that are inappropriate if fchown fails.
1506
1507 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
1508
1509 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
1510 to compare Lisp_Objects.
1511 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
1512 global_gnutls_log_level, don't mistake it for a Lisp_Object.
1513 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
1514
1515 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
1516
1517 * lread.c (read_integer): Unread even EOF character.
1518 (read1): Likewise. Properly record start position of symbol.
1519
1520 * lread.c (read1): Read `#:' as empty uninterned symbol if no
1521 symbol character follows.
1522
1523 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
1524
1525 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
1526 This works around a problem with the previous change to Fcopy_file.
1527 Recent glibc declares fchown with __attribute__((warn_unused_result)),
1528 and without this change, GCC might complain about discarding
1529 fchown's return value.
1530
1531 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
1532
1533 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
1534
1535 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
1536
1537 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
1538
1539 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
1540
1541 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
1542 it's used from the C level.
1543
1544 * process.c: Use the same condition for POLL_FOR_INPUT in both
1545 keyboard.c and process.c (bug#1858).
1546
1547 2011-07-09 Lawrence Mitchell <wence@gmx.li>
1548
1549 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
1550 (Fgnutls_boot): Use it.
1551
1552 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
1553
1554 * doc.c (Fsubstitute_command_keys): Revert last change.
1555
1556 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
1557
1558 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
1559 quotes the next character, and doesn't affect other longer
1560 sequences (bug#8935).
1561
1562 * lread.c (syms_of_lread): Clarify that is isn't only
1563 `eval-buffer' and `eval-defun' that's affected by
1564 `lexical-binding' (bug#8460).
1565
1566 2011-07-15 Eli Zaretskii <eliz@gnu.org>
1567
1568 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
1569 bidi redisplay when a line includes both an image and is
1570 truncated.
1571
1572 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
1573
1574 Fix minor problems found by static checking.
1575 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
1576 (elsz): Now a signed constant, not a size_t var. We prefer signed
1577 types to unsigned, to avoid integer comparison confusion. Without
1578 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
1579 "cannot optimize loop, the loop counter may overflow", a symptom
1580 of the confusion.
1581 * indent.c (Fvertical_motion): Mark locals as initialized.
1582 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
1583
1584 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
1585
1586 * search.c (Fre_search_backward): Mention `case-fold-search' in
1587 all the re_search_* functions (bug#8138).
1588
1589 * keyboard.c (Fopen_dribble_file): Document when the file is
1590 closed (bug#8056).
1591
1592 2011-07-14 Eli Zaretskii <eliz@gnu.org>
1593
1594 * bidi.c (bidi_dump_cached_states): Fix format of displaying
1595 bidi_cache_idx.
1596
1597 Support bidi reordering of display and overlay strings.
1598 * xdisp.c (compute_display_string_pos)
1599 (compute_display_string_end): Accept additional argument STRING.
1600 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
1601 (reseat_to_string): Initialize bidi_it->string.s and
1602 bidi_it->string.schars.
1603 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
1604 NULL (avoids a crash in bidi_paragraph_init).
1605 Initialize itb.string.lstring.
1606 (init_iterator): Call bidi_init_it only of a valid
1607 buffer position was specified. Initialize paragraph_embedding to
1608 L2R.
1609 (reseat_to_string): Initialize the bidi iterator.
1610 (display_string): If we need to ignore text properties of
1611 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
1612 original value of -1 will not work with bidi.)
1613 (compute_display_string_pos): First arg is now struct
1614 `text_pos *'; all callers changed. Support display properties on
1615 Lisp strings.
1616 (compute_display_string_end): Support display properties on Lisp
1617 strings.
1618 (init_iterator, reseat_1, reseat_to_string): Initialize the
1619 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
1620 when iterating on a string not from display properties).
1621 (compute_display_string_pos, compute_display_string_end):
1622 Fix calculation of the object to scan. Fixes an error when using
1623 arrow keys.
1624 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
1625 base_level_stop; instead, set base_level_stop to BEGV.
1626 Fixes crashes in vertical-motion.
1627 (next_element_from_buffer): Improve commentary for when
1628 the iterator is before prev_stop.
1629 (init_iterator): Initialize bidi_p from the default value of
1630 bidi-display-reordering, not from buffer-local value. Use the
1631 buffer-local value only if initializing for buffer iteration.
1632 (handle_invisible_prop): Support invisible properties on strings
1633 that are being bidi-reordered.
1634 (set_iterator_to_next): Support bidi reordering of C strings and
1635 Lisp strings.
1636 (next_element_from_string): Support bidi reordering of Lisp
1637 strings.
1638 (handle_stop_backwards): Support Lisp strings as well.
1639 (display_string): Support display of R2L glyph rows.
1640 Use IT_STRING_CHARPOS when displaying from a Lisp string.
1641 (init_iterator): Don't initialize it->bidi_p for strings
1642 here.
1643 (reseat_to_string): Initialize it->bidi_p for strings here.
1644 (next_element_from_string, next_element_from_c_string)
1645 (next_element_from_buffer): Add xassert's for correspondence
1646 between IT's object being iterated and it->bidi_it.string
1647 structure.
1648 (face_before_or_after_it_pos): Support bidi iteration.
1649 (next_element_from_c_string): Handle the case of the first string
1650 character that is not the first one in the visual order.
1651 (get_visually_first_element): New function, refactored from common
1652 parts of next_element_from_buffer, next_element_from_string, and
1653 next_element_from_c_string.
1654 (tool_bar_lines_needed, redisplay_tool_bar)
1655 (display_menu_bar): Force left-to-right direction. Add a FIXME
1656 comment for making that be controlled by a user option.
1657 (push_it, pop_it): Save and restore the state of the
1658 bidi iterator. Save and restore the bidi_p flag.
1659 (pop_it): Iterate out of display property for string iteration as
1660 well.
1661 (iterate_out_of_display_property): Support iteration over strings.
1662 (handle_single_display_spec): Set up it->bidi_it for iteration
1663 over a display string, and call bidi_init_it.
1664 (handle_single_display_spec, next_overlay_string)
1665 (get_overlay_strings_1, push_display_prop): Set up the bidi
1666 iterator for displaying display or overlay strings.
1667 (forward_to_next_line_start): Don't use the shortcut if
1668 bidi-iterating.
1669 (back_to_previous_visible_line_start): If handle_display_prop
1670 pushed the iterator stack, restore the internal state of the bidi
1671 iterator by calling bidi_pop_it same number of times.
1672 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
1673 and we are bidi-iterating, don't decrement the iterator position;
1674 instead, set the first_elt flag in the bidi iterator, to produce
1675 the same effect.
1676 (reseat_1): Remove redundant setting of string_from_display_prop_p.
1677 (push_display_prop): xassert that we are iterating a buffer.
1678 (push_it, pop_it): Save and restore paragraph_embedding member.
1679 (handle_single_display_spec, next_overlay_string)
1680 (get_overlay_strings_1, reseat_1, reseat_to_string)
1681 (push_display_prop): Set up the `unibyte' member of bidi_it.string
1682 correctly. Don't assume unibyte strings are not bidi-reordered.
1683 (compute_display_string_pos)
1684 (compute_display_string_end): Fix handling the case of C string.
1685 (push_it, pop_it): Save and restore from_disp_prop_p.
1686 (handle_single_display_spec, push_display_prop): Set the
1687 from_disp_prop_p flag.
1688 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
1689 (pop_it): Call iterate_out_of_display_property only if we are
1690 popping after iteration over a string that came from a display
1691 property. Fix a typo in popping stretch info. Add an assertion
1692 for verifying that the iterator position is in sync with the bidi
1693 iterator.
1694 (handle_single_display_spec, get_overlay_strings_1)
1695 (push_display_prop): Fix initialization of paragraph direction for
1696 string when that of the parent object is not yet determined.
1697 (reseat_1): Call bidi_init_it to resync the bidi
1698 iterator with IT's position. (Bug#7616)
1699 (find_row_edges): If ROW->start.pos gives position
1700 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
1701 (handle_stop, back_to_previous_visible_line_start, reseat_1):
1702 Reset the from_disp_prop_p flag.
1703 (SAVE_IT, RESTORE_IT): New macros.
1704 (pos_visible_p, face_before_or_after_it_pos)
1705 (back_to_previous_visible_line_start)
1706 (move_it_in_display_line_to, move_it_in_display_line)
1707 (move_it_to, move_it_vertically_backward, move_it_by_lines)
1708 (try_scrolling, redisplay_window, display_line): Use them when
1709 saving a temporary copy of the iterator and restoring it back.
1710 (back_to_previous_visible_line_start, reseat_1)
1711 (init_iterator): Empty the bidi cache "stack".
1712 (move_it_in_display_line_to): If iterator ended up at
1713 EOL, but we never saw any buffer positions smaller than
1714 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
1715 motion in bidi-reordered lines.
1716 (move_it_in_display_line_to): Record prev_method and prev_pos
1717 immediately before the call to set_iterator_to_next. Fixes cursor
1718 motion in bidi-reordered lines with stretch glyphs and strings
1719 displayed in margins. (Bug#8133) (Bug#8867)
1720 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
1721 TO_CHARPOS.
1722 (pos_visible_p): Support positions in bidi-reordered lines.

2143
2144 Random fixes. E.g., (random) never returned negative values.
2145 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
2146 subseconds part to the entropy, as that's a bit more random.
2147 Prefer signed to unsigned, since the signedness doesn't matter and
2148 in general we prefer signed. When given a limit, use a
2149 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
2150 latter isn't right if USE_2_TAGS_FOR_INTS.
2151 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
2152 not 0..VALMASK. Don't discard "excess" bits that random () returns.
2153
2154 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2155
2156 * textprop.c (text_property_stickiness):

2161
2162 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
2163
2164 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
2165 This is more efficient than Ffile_directory_p and avoids a minor race.
2166
2167 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
2168
2169 * buffer.c (Foverlay_put): Say what the return value is
2170 (bug#7835).
2171

2176 error be more correct.

2190 (syms_of_gnutls): Remove duplicate DEFSYM for
2191 Qgnutls_bootprop_verify_hostname_error, an error for
2192 Qgnutls_bootprop_verify_error (which is no longer used).
2193
2194 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
2195 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
2196 Also (re)move comments that are misplaced or no longer relevant.
2197

2223 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>
2224

2278 (emacs_settings_set_property, emacs_settings_class_init)
2279 (emacs_settings_init, gsettings_obj): Remove.

2297 * eval.c (struct backtrace): Simplify and port the data structure.
2298 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
2299 signed bit field, as this assumption is not portable and it makes
2300 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
2301 "char debug_on_exit : 1" as this is not portable either; instead,
2302 use the portable "unsigned int debug_on_exit : 1". Remove unused
2303 member evalargs. Remove obsolete comments about cc bombing out.
2304
2305 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

2345 * buffer.c (Qclone_number): Declare static and DEFSYM it.
2346 (sort_overlays, overlay_strings): When an overlay's clone number
2347 matches the window's clone number process the overlay even if
2348 the overlay's window property doesn't match the current window.
2349
2350 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.
2351 (Fwindow_hchild): Rename to Fwindow_left_child.

2380
2381 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
2382 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.

2386
2387 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
2388 bidi_at_paragraph_end, since fast_looking_at doesn't like to be

2472 (PRINTPREPARE, printchar, strout):
2473 Don't set size unless allocation succeeds.
2474
2475 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
2476 for sizes. Check for string overflow more accurately.
2477 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
2478
2479 * macros.c: Integer and buffer overflow fixes.
2480 * keyboard.h (struct keyboard.kbd_macro_bufsize):
2481 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

2487 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
2488
2489 * lread.c: Integer overflow fixes.
2490 (read_integer): Radix is now EMACS_INT, not int,
2491 to improve quality of diagnostics for out-of-range radices.
2492 Calculate buffer size correctly for out-of-range radices.
2493 (read1): Check for integer overflow in radices, and in
2494 read-circle numbers.
2495 (read_escape): Avoid int overflow.
2496 (Fload, openp, read_buffer_size, read1)
2497 (substitute_object_recurse, read_vector, read_list, map_obarray):
2498 Use ptrdiff_t, not int, for sizes.
2499 (read1): Use EMACS_INT, not int, for sizes.

2518 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
2519
2520 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
2521 The following patches are for when GLYPH_DEBUG && !XASSERT.
2522 * dispextern.h (trace_redisplay_p, dump_glyph_string):
2523 * dispnew.c (flush_stdout):
2524 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
2525 Mark as externally visible.
2526 * dispnew.c (check_window_matrix_pointers): Now static.
2527 * dispnew.c (window_to_frame_vpos):
2528 * xfns.c (unwind_create_frame):
2529 * xterm.c (x_check_font): Remove unused local.
2530 * scroll.c (CHECK_BOUNDS):
2531 * xfaces.c (cache_fache): Rename local to avoid shadowing.
2532 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
2533 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
2534 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
2535 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
2536 Now static.
2537 (debug_method_add): Use va_list and vsprintf rather than relying
2538 on undefined behavior with wrong number of arguments.
2539 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
2540 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
2541 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
2542 since we're not interested in debugging glyphs with old libraries.
2543 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
2544 GCC 4.6.0's static checking.
2545
2546 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
2547

2560 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
2561 (.bitmaps_last):
2562 * xfaces.c (load_pixmap):
2563 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
2564 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
2565 (.bitmaps_last, struct x_output.icon_bitmap):
2566 Use ptrdiff_t, not int, for bitmap indexes.
2567 (x_allocate_bitmap_record): Check for size overflow.
2568 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
2569
2570 Use ptrdiff_t, not int, for overlay counts.
2571 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
2572 * editfns.c (overlays_around, get_pos_property):
2573 * textprop.c (get_char_property_and_overlay):
2574 * xdisp.c (next_overlay_change, note_mouse_highlight):
2575 * xfaces.c (face_at_buffer_position):
2576 * buffer.c (OVERLAY_COUNT_MAX): New macro.
2577 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
2578 (Fnext_overlay_change, Fprevious_overlay_change)
2579 (mouse_face_overlay_overlaps, Foverlays_in):
2580 Use ptrdiff_t, not int, for sizes.
2581 (overlays_at, overlays_in): Check for size-calculation overflow.
2582
2583 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
2584
2585 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
2586 (x_session_initialize): Do not assume string length fits in int.
2587
2588 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
2589 This is unlikely, but can occur if DPI is outlandish.
2590
2591 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
2592 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
2593
2594 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
2595 * xrdb.c (magic_file_p, search_magic_path):
2596 Omit last arg SUFFIX; it was always 0. All callers changed.
2597 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
2598
2599 * xfont.c (xfont_match): Avoid need for strlen.
2600
2601 * xfns.c: Don't assume strlen fits in int.
2602 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
2603
2604 * xdisp.c (message_log_check_duplicate): Return intmax_t,
2605 not unsigned long, as we prefer signed integers. All callers changed.
2606 Detect integer overflow in repeat count.
2607 (message_dolog): Don't assume print length fits in 39 bytes.
2608 (display_mode_element): Don't assume strlen fits in int.
2609
2610 * termcap.c: Don't assume sizes fit in int and never overflow.
2611 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
2612 (gobble_line): Check for size-calculation overflow.
2613
2614 * minibuf.c (Fread_buffer):
2615 * lread.c (intern, intern_c_string):
2616 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
2617 Don't assume string length fits in int.
2618
2619 * keyboard.c (parse_tool_bar_item):
2620 * gtkutil.c (style_changed_cb): Avoid need for strlen.
2621
2622 * font.c: Don't assume string length fits in int.
2623 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
2624 Use ptrdiff_t, not int.
2625 (font_intern_prop): Don't assume string length fits in int.
2626 Don't assume integer property fits in fixnum.
2627 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
2628
2629 * filelock.c: Fix some buffer overrun and integer overflow issues.
2630 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
2631 Reformulate so as not to need the command string.
2632 Invoke gzip -cd rather than gunzip, as it's more portable.
2633 (lock_info_type, lock_file_1, lock_file):
2634 Don't assume pid_t and time_t fit in unsigned long.
2635 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
2636 (current_lock_owner): Prefer signed type for sizes.
2637 Use memcpy, not strncpy, where memcpy is what is really wanted.
2638 Don't assume (via atoi) that time_t and pid_t fit in int.
2639 Check for time_t and/or pid_t out of range, e.g., via a network share.
2640 Don't alloca where an auto var works fine.
2641
2642 * fileio.c: Fix some integer overflow issues.
2643 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
2644 Don't assume string length fits in int.
2645 (directory_file_name): Don't assume string length fits in long.
2646 (make_temp_name): Don't assume pid fits in int, or that its print
2647 length is less than 20.
2648
2649 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
2650
2651 * coding.c (make_subsidiaries): Don't assume string length fits in int.
2652
2653 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
2654
2655 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
2656 We prefer signed integers, even for size calculations.
2657
2658 * emacs.c: Don't assume string length fits in 'int'.
2659 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
2660 (main): Don't invoke strlen when not needed.
2661
2662 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
2663 (XD_DEBUG_MESSAGE): Don't waste a byte.
2664
2665 * callproc.c (getenv_internal_1, getenv_internal)
2666 (Fgetenv_internal):
2667 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
2668
2669 * lread.c (invalid_syntax): Omit length argument.
2670 All uses changed. This doesn't fix a bug, but it simplifies the
2671 code away from its former Hollerith-constant appearance, and it's
2672 one less 'int' to worry about when looking at integer-overflow issues.
2673 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
2674
2675 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
2676 This didn't break anything, but it didn't help either.
2677 It's confusing to put a bogus integer in a place where the actual
2678 value does not matter.
2679 (LIST_END_P): Remove unused macro and its bogus comment.
2680 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
2681
2682 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
2683 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
2684 implementation.
2685 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
2686 We prefer signed types, and the value cannot exceed the EMACS_INT
2687 range anyway (because otherwise the length would not be representable).
2688 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
2689 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
2690 This avoids a GCC warning when WIDE_EMACS_INT.
2691
2692 * indent.c (sane_tab_width): New function.
2693 (current_column, scan_for_column, Findent_to, position_indentation)
2694 (compute_motion): Use it. This is just for clarity.
2695 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
2696
2697 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
2698
2699 * lisp.h (lint_assume): New macro.
2700 * composite.c (composition_gstring_put_cache):
2701 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
2702
2703 * editfns.c, insdel.c:
2704 Omit unnecessary forward decls, to simplify future changes.
2705
2706 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
2707
2708 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
2709
2710 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
2711 Use much-faster test for byte-length change.
2712 Don't assume string byte-length fits in 'int'.
2713 Check that character arg fits in 'int'.
2714 (mapcar1): Declare byte as byte, for clarity.
2715
2716 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
2717
2718 * fns.c (concat): Catch string overflow earlier.
2719 Do not rely on integer wraparound.
2720
2721 * dispextern.h (struct it.overlay_strings_charpos)
2722 (struct it.selective): Now EMACS_INT, not int.
2723 * xdisp.c (forward_to_next_line_start)
2724 (back_to_previous_visible_line_start)
2725 (reseat_at_next_visible_line_start, next_element_from_buffer):
2726 Don't arbitrarily truncate the value of 'selective' to int.
2727
2728 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
2729
2730 * composite.c: Don't truncate sizes to 'int'.
2731 (composition_gstring_p, composition_reseat_it)
2732 (composition_adjust_point): Use EMACS_INT, not int.
2733 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
2734 not EMACS_UINT, for indexes.
2735
2736 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
2737
2738 * buffer.c: Include <verify.h>.
2739 (struct sortvec.priority, struct sortstr.priority):
2740 Now EMACS_INT, not int.
2741 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
2742 (struct sortstr.size, record_overlay_string)
2743 (struct sortstrlist.size, struct sortlist.used):
2744 Don't truncate size to int.
2745 (record_overlay_string): Check for size-calculation overflow.
2746 (init_buffer_once): Check at compile-time, not run-time.
2747
2748 2011-06-22 Jim Meyering <meyering@redhat.com>
2749
2750 Don't leak an XBM-image-sized buffer
2751 * image.c (xbm_load): Free the image buffer after using it.
2752
2753 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
2754
2755 Port to Sun C.
2756 * composite.c (find_automatic_composition): Omit needless 'return 0;'
2757 that Sun C diagnosed.
2758 * fns.c (secure_hash): Fix pointer signedness issue.
2759 * intervals.c (static_offset_intervals): New function.
2760 (offset_intervals): Use it.
2761
2762 2011-06-21 Leo Liu <sdl.web@gmail.com>
2763
2764 * deps.mk (fns.o):
2765 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
2766 sha512.h.
2767
2768 * fns.c (secure_hash): Rename from crypto_hash_function and change
2769 the first arg to accept symbols.
2770 (Fsecure_hash): New primitive.
2771 (syms_of_fns): New symbols.
2772
2773 2011-06-20 Deniz Dogan <deniz@dogan.se>
2774
2775 * process.c (Fset_process_buffer): Clarify return value in
2776 docstring.
2777
2778 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
2779
2780 * dispnew.c (add_window_display_history): Use BVAR.
2781
2782 * xdisp.c (debug_method_add): Use BVAR.
2783 (check_window_end, dump_glyph_matrix, dump_glyph)
2784 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
2785
2786 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
2787 Likewise.
2788
2789 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
2790 check till after the cache is created in init_frame_faces.
2791
2792 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
2793
2794 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
2795
2796 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
2797
2798 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
2799 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
2800 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
2801
2802 Improve buffer-overflow checking (Bug#8873).
2803 * fileio.c (Finsert_file_contents):
2804 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
2805 Remove the old (too-loose) buffer overflow checks.
2806 They weren't needed, since make_gap checks for buffer overflow.
2807 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
2808 The old code merely checked for Emacs fixnum overflow, and relied
2809 on undefined (wraparound) behavior. The new code avoids undefined
2810 behavior, and also checks for ptrdiff_t and/or size_t overflow.
2811
2812 * editfns.c (Finsert_char): Don't dump core with very negative counts.
2813 Tune. Don't use wider integers than needed. Don't use alloca.
2814 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
2815
2816 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
2817
2818 * insdel.c, lisp.h (buffer_overflow): New function.
2819 (insert_from_buffer_1, replace_range, replace_range_2):
2820 * insdel.c (make_gap_larger):
2821 * editfns.c (Finsert_char):
2822 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
2823
2824 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
2825
2826 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
2827
2828 Integer overflow and signedness fixes (Bug#8873).
2829
2830 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
2831 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
2832
2833 * fileio.c: Don't assume EMACS_INT fits in off_t.
2834 (emacs_lseek): New static function.
2835 (Finsert_file_contents, Fwrite_region): Use it.
2836 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
2837
2838 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
2839
2840 * fns.c: Don't overflow int when computing a list length.
2841 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
2842 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
2843 truncation on 64-bit hosts. Check for QUIT every
2844 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
2845 faster and is responsive enough.
2846 (Flength): Report an error instead of overflowing an integer.
2847 (Fsafe_length): Return a float if the value is not representable
2848 as a fixnum. This shouldn't happen except in contrived situations.
2849 (Fnthcdr, Fsort): Don't assume list length fits in int.
2850 (Fcopy_sequence): Don't assume vector length fits in int.
2851
2852 * alloc.c: Check that resized vectors' lengths fit in fixnums.
2853 (header_size, word_size): New constants.
2854 (allocate_vectorlike): Don't check size overflow here.
2855 (allocate_vector): Check it here instead, since this is the only
2856 caller of allocate_vectorlike that could cause overflow.
2857 Check that the new vector's length is representable as a fixnum.
2858
2859 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
2860 The previous code was bogus. For example, next_almost_prime (32)
2861 returned 39, which is undesirable as it is a multiple of 3; and
2862 next_almost_prime (24) returned 25, which is a multiple of 5 so
2863 why was the code bothering to check for multiples of 7?
2864
2865 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
2866
2867 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
2868
2869 Variadic C functions now count arguments with ptrdiff_t.
2870 This partly undoes my 2011-03-30 change, which replaced int with size_t.
2871 Back then I didn't know that the Emacs coding style prefers signed int.
2872 Also, in the meantime I found a few more instances where arguments
2873 were being counted with int, which may truncate counts on 64-bit
2874 machines, or EMACS_INT, which may be unnecessarily wide.
2875 * lisp.h (struct Lisp_Subr.function.aMANY)
2876 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
2877 Arg counts are now ptrdiff_t, not size_t.
2878 All variadic functions and their callers changed accordingly.
2879 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
2880 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
2881 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
2882 * callint.c (Fcall_interactively): Check arg count for overflow,
2883 to avoid potential buffer overrun. Use signed char, not 'int',
2884 for 'varies' array, so that we needn't bother to check its size
2885 calculation for overflow.
2886 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
2887 * eval.c (apply_lambda):
2888 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
2889 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
2890 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
2891
2892 * callint.c (Fcall_interactively): Don't use index var as event count.
2893
2894 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
2895 * mem-limits.h (SIZE): Remove; no longer used.
2896
2897 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
2898
2899 Remove unnecessary casts.
2900 * xterm.c (x_term_init):
2901 * xfns.c (x_set_border_pixel):
2902 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
2903 These aren't needed now that we assume ANSI C.
2904
2905 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
2906 It's more likely to cause problems (due to unsigned overflow)
2907 than to cure them.
2908
2909 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
2910
2911 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
2912
2913 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
2914
2915 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
2916
2917 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
2918
2919 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
2920
2921 GLYPH_CODE_FACE returns EMACS_INT, not int.
2922 * dispextern.h (merge_faces):
2923 * xfaces.c (merge_faces):
2924 * xdisp.c (get_next_display_element, next_element_from_display_vector):
2925 Don't assume EMACS_INT fits in int.
2926
2927 * character.h (CHAR_VALID_P): Remove unused parameter.
2928 * fontset.c, lisp.h, xdisp.c: All uses changed.
2929
2930 * editfns.c (Ftranslate_region_internal): Omit redundant test.
2931
2932 * fns.c (concat): Minor tuning based on overflow analysis.
2933 This doesn't fix any bugs. Use int to hold character, instead
2934 of constantly refetching from Emacs object. Use XFASTINT, not
2935 XINT, for value known to be a character. Don't bother comparing
2936 a single byte to 0400, as it's always less.
2937
2938 * floatfns.c (Fexpt):
2939 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
2940
2941 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
2942 for characters.
2943
2944 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
2945
2946 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
2947 Without this fix, on a 64-bit host (aset S 0 4294967386) would
2948 incorrectly succeed when S was a string, because 4294967386 was
2949 truncated before it was used.
2950
2951 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
2952 Otherwise, an out-of-range integer could cause undefined behavior
2953 on a 64-bit host.
2954
2955 * composite.c: Use int, not EMACS_INT, for characters.
2956 (fill_gstring_body, composition_compute_stop_pos): Use int, not
2957 EMACS_INT, for values that are known to be in character range.
2958 This doesn't fix any bugs but is the usual style inside Emacs and
2959 may generate better code on 32-bit machines.
2960
2961 Make sure a 64-bit char is never passed to ENCODE_CHAR.
2962 This is for reasons similar to the recent CHAR_STRING fix.
2963 * charset.c (Fencode_char): Check that character arg is actually
2964 a character. Pass an int to ENCODE_CHAR.
2965 * charset.h (ENCODE_CHAR): Verify that the character argument is no
2966 wider than 'int', as a compile-time check to prevent future regressions
2967 in this area.
2968
2969 * character.c (char_string): Remove unnecessary casts.
2970
2971 Make sure a 64-bit char is never passed to CHAR_STRING.
2972 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
2973 by silently ignoring the top 32 bits, allowing some values
2974 that were far too large to be valid characters.
2975 * character.h: Include <verify.h>.
2976 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
2977 arguments are no wider than unsigned, as a compile-time check
2978 to prevent future regressions in this area.
2979 * data.c (Faset):
2980 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
2981 (Fsubst_char_in_region):
2982 * fns.c (concat):
2983 * xdisp.c (decode_mode_spec_coding):
2984 Adjust to CHAR_STRING's new requirement.
2985 * editfns.c (Finsert_char, Fsubst_char_in_region):
2986 * fns.c (concat): Check that character args are actually
2987 characters. Without this test, these functions did the wrong
2988 thing with wildly out-of-range values on 64-bit hosts.
2989
2990 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
2991 These casts should not be needed on 32-bit hosts, either.
2992 * keyboard.c (read_char):
2993 * lread.c (Fload): Remove casts to unsigned.
2994
2995 * lisp.h (UNSIGNED_CMP): New macro.
2996 This fixes comparison bugs on 64-bit hosts.
2997 (ASCII_CHAR_P): Use it.
2998 * casefiddle.c (casify_object):
2999 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
3000 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
3001 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
3002 * dispextern.h (FACE_FROM_ID):
3003 * keyboard.c (read_char): Use UNSIGNED_CMP.
3004
3005 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
3006 not to EMACS_INT, to avoid GCC warning.
3007
3008 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
3009
3010 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
3011 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
3012 isn't needed on 32-bit machines.
3013
3014 * buffer.c (Fgenerate_new_buffer_name):
3015 Use EMACS_INT for count, not int.
3016 (advance_to_char_boundary): Return EMACS_INT, not int.
3017
3018 * data.c (Qcompiled_function): Now static.
3019
3020 * window.c (window_body_lines): Now static.
3021
3022 * image.c (gif_load): Rename local to avoid shadowing.
3023
3024 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
3025 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
3026 * alloc.c (make_save_value): Integer argument is now of type
3027 ptrdiff_t, not int.
3028 (mark_object): Use ptrdiff_t, not int.
3029 * lisp.h (pD): New macro.
3030 * print.c (print_object): Use it.
3031
3032 * alloc.c: Use EMACS_INT, not int, to count objects.
3033 (total_conses, total_markers, total_symbols, total_vector_size)
3034 (total_free_conses, total_free_markers, total_free_symbols)
3035 (total_free_floats, total_floats, total_free_intervals)
3036 (total_intervals, total_strings, total_free_strings):
3037 Now EMACS_INT, not int. All uses changed.
3038 (Fgarbage_collect): Compute overall total using a double, so that
3039 integer overflow is less likely to be a problem. Check for overflow
3040 when converting back to an integer.
3041 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
3042 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
3043 These were 'int' variables that could overflow on 64-bit hosts;
3044 they were never used, so remove them instead of repairing them.
3045 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
3046 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
3047 Previously, this ceilinged at INT_MAX, but that doesn't work on
3048 64-bit machines.
3049 (allocate_pseudovector): Don't use EMACS_INT when int would do.
3050
3051 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
3052 (allocate_vectorlike): Check for ptrdiff_t overflow.
3053 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
3054 when a (possibly-narrower) signed value would do just as well.
3055 We prefer using signed arithmetic, to avoid comparison confusion.
3056
3057 * alloc.c: Catch some string size overflows that we were missing.
3058 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
3059 for convenience in STRING_BYTES_MAX.
3060 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
3061 The definition here is exact; the one in lisp.h was approximate.
3062 (allocate_string_data): Check for string overflow. This catches
3063 some instances we weren't catching before. Also, it catches
3064 size_t overflow on (unusual) hosts where SIZE_MAX <= min
3065 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
3066 and ptrdiff_t and EMACS_INT are both 64 bits.
3067
3068 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
3069 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
3070 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
3071
3072 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
3073
3074 * alloc.c (Fmake_string): Check for out-of-range init.

3107 other_buffer.
3108
3109 * window.c (temp_output_buffer_show): Call display_buffer with
3110 second argument Vtemp_buffer_show_specifiers and reset latter
3111 immediately after the call.

3576 only if SYSTEM_MALLOC.
3577 (LARGE_REQUEST): New macro, so that the issue of large requests
3578 is separated from the issue of spare memory.
3579
3580 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
3581

3638 display string.
3639 (bidi_paragraph_init, bidi_resolve_explicit_1)
3640 (bidi_level_of_next_char): Call bidi_fetch_char and

3647 instead of using explicit *_CHAR codes.
3648 (bidi_resolve_explicit, bidi_resolve_weak):
3649 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
3650 bidirectional text is supported only in multibyte buffers.

3659 were just reseat()'ed to a new position.
3660
3661 * xdisp.c (set_cursor_from_row): Set start and stop points
3662 according to the row's direction when priming the loop that looks

3665 (display_prop_intangible_p): Reimplement to call
3666 handle_display_spec instead of single_display_spec_intangible_p.
3667 Accept 3 additional arguments needed by handle_display_spec.
3668 This fixes incorrect cursor motion across display property with complex
3669 values: lists, `(when COND...)' forms, etc.
3670 (single_display_spec_string_p): Support property values that are
3671 lists with the argument STRING its top-level element.
3672 (display_prop_string_p): Fix the condition for processing a
3673 property that is a list to be consistent with handle_display_spec.

3675 last portion of handle_display_prop.
3676 (compute_display_string_pos): Accept additional argument

3678 value of a `display' property is a "replacing spec".
3679 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
3680 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

3694 * dispextern.h (struct bidi_it): New member frame_window_p.
3695 (bidi_init_it): Update prototypes.

3708 All callers changed. (Bug#8762)
3709
3710 * gnutls.c: Use Emacs's memory allocators.
3711 Without this change, the gnutls library would invoke malloc etc.
3712 directly, which causes problems on non-SYNC_INPUT hosts, and which
3713 runs afoul of improving memory_full behavior. (Bug#8761)
3714 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
3715 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
3716 xfree instead of the default malloc, realloc, free.
3717 (Fgnutls_boot): No need to check for memory allocation failure,
3718 since xmalloc does that for us.
3719

3738 * lisp.h (struct Lisp_Hash_Table):
3739 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
3740 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
3741 for hashes and hash indexes, instead of 'unsigned' and 'int'.
3742 * alloc.c (allocate_vectorlike):
3743 Check for overflow in vector size calculations.
3744 * ccl.c (ccl_driver):
3745 Check for overflow when converting EMACS_INT to int.

3747 need to be updated by these changes.
3748 * fns.c (make_hash_table, maybe_resize_hash_table):
3749 Check for integer overflow with large hash tables.
3750 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
3751 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
3752 (SXHASH_REDUCE): New macro.
3753 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
3754 Use it instead of discarding useful hash info with large hash values.
3755 (sxhash_float): New function.
3756 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
3757 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
3758 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
3759 Rewrite to use FIXNUM_BITS, as this simplifies things.
3760 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
3761 Adjust signatures to match updated version of code.
3762 (consing_since_gc): Now EMACS_INT, since a single hash table can
3763 use more than INT_MAX bytes.
3764

3793
3794 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3795
3796 * dispnew.c (add_window_display_history): Use const for the string
3797 pointer. Remove declaration, not needed.
3798
3799 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3800
3801 Use 'inline', not 'INLINE'.
3802 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
3803 * alloc.c, fontset.c (INLINE): Remove.
3804 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
3805 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
3806 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
3807 * gmalloc.c (register_heapinfo): Use inline unconditionally.
3808 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
3809
3810 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
3811
3812 Make it possible to run ./temacs.
3813
3814 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
3815 syms_of_callproc does the same thing. Remove test for
3816 "initialized", do it in the caller.
3817 * emacs.c (main): Avoid calling set_initial_environment when dumping.
3818
3819 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
3820
3821 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
3822 (read_minibuf): Use get_minibuffer.
3823 (syms_of_minibuf): Use DEFSYM.
3824 (Qmetadata): New var.
3825 * data.c (Qbuffer): Don't make it static.
3826 (syms_of_data): Use DEFSYM.
3827
3828 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
3829
3830 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
3831 (CCL_CODE_MIN): New macro.
3832
3833 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
3834
3835 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
3836
3837 * eval.c (Qdebug): Now static.
3838 * lisp.h (Qdebug): Remove decl. This reverts a part of the
3839 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
3840 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
3841
3842 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3843
3844 * image.c: Various fixes to ImageMagick code comments.
3845 (Fimagemagick_types): Doc fix.
3846
3847 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
3848
3849 Minor fixes prompted by GCC 4.6.0 warnings.
3850
3851 * xselect.c (converted_selections, conversion_fail_tag): Now static.
3852
3853 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
3854 (x_clipboard_manager_save_all): Move extern decl to ...
3855 * xterm.h: ... here, so that it can be checked for consistency.
3856
3857 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
3858
3859 * xselect.c (x_clipboard_manager_save_frame)
3860 (x_clipboard_manager_save_all): New functions.
3861 (Fx_clipboard_manager_save): Lisp function deleted.
3862
3863 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
3864 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
3865
3866 * xterm.h: Update prototype.
3867
3868 2011-05-28 William Xu <william.xwl@gmail.com>
3869
3870 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
3871 exiting (Bug#8239).
3872
3873 2011-05-28 Jim Meyering <meyering@redhat.com>
3874
3875 Avoid a sign-extension bug in crypto_hash_function.
3876 * fns.c (to_uchar): Define.
3877 (crypto_hash_function): Use it to convert some newly-signed
3878 variables to unsigned, to avoid sign-extension bugs. For example,
3879 without this change, (md5 "truc") would evaluate to
3880 45723a2aff78ff4fff7fff1114760e62 rather than the expected
3881 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
3882 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
3883
3884 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3885
3886 Integer overflow fixes.
3887
3888 * dbusbind.c: Serial number integer overflow fixes.
3889 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
3890 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
3891 to hold a serial number that is too large for a fixnum.
3892 (Fdbus_method_return_internal, Fdbus_method_error_internal):
3893 Check for serial numbers out of range. Decode any serial number
3894 that was so large that it became a float. (Bug#8722)
3895
3896 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
3897 (Fdbus_call_method, Fdbus_call_method_asynchronously):
3898 Use XFASTINT rather than XUINT when numbers are nonnegative.
3899 (xd_append_arg, Fdbus_method_return_internal):
3900 (Fdbus_method_error_internal): Likewise. Also, for unsigned
3901 arguments, check that Lisp number is nonnegative, rather than
3902 silently wrapping negative numbers around. (Bug#8722)
3903 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
3904 (Bug#8722)
3905
3906 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
3907
3908 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
3909
3910 ccl: add integer overflow checks
3911 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
3912 (IN_INT_RANGE): New macros.
3913 (ccl_driver): Use them to check for integer overflow when
3914 decoding a CCL program. Many of the new checks are whether XINT (x)
3915 fits in int; it doesn't always, on 64-bit hosts. The new version
3916 doesn't catch all possible integer overflows, but it's an
3917 improvement. (Bug#8719)
3918
3919 * alloc.c (make_event_array): Use XINT, not XUINT.
3920 There's no need for unsigned here.
3921
3922 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
3923 This follows up to the 2011-05-06 change that substituted uintptr_t
3924 for EMACS_INT. This case wasn't caught back then.
3925
3926 Rework Fformat to avoid integer overflow issues.
3927 * editfns.c: Include <float.h> unconditionally, as it's everywhere
3928 now (part of C89). Include <verify.h>.
3929 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
3930 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
3931 (Fformat): Avoid the prepass trying to compute sizes; it was only
3932 approximate and thus did not catch overflow reliably. Instead, walk
3933 through the format just once, formatting and computing sizes as we go,
3934 checking for integer overflow at every step, and allocating a larger
3935 buffer as needed. Keep track separately whether the format is
3936 multibyte. Keep only the most-recently calculated precision, rather
3937 than them all. Record whether each argument has been converted to
3938 string. Use EMACS_INT, not int, for byte and char and arg counts.
3939 Support field widths and precisions larger than INT_MAX. Avoid
3940 sprintf's undefined behavior with conversion specifications such as %#d
3941 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
3942 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
3943 formatting out-of-range floating point numbers with int
3944 formats. (Bug#8668)
3945
3946 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
3947
3948 * data.c: Avoid integer truncation in expressions involving floats.
3949 * data.c: Include <intprops.h>.
3950 (arith_driver): When there's an integer overflow in an expression
3951 involving floating point, convert the integers to floating point
3952 so that the resulting value does not suffer from catastrophic
3953 integer truncation. For example, on a 64-bit host (* 4
3954 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
3955 Do not rely on undefined behavior after integer overflow.
3956
3957 merge count_size_as_multibyte, parse_str_to_multibyte
3958 * character.c, character.h (count_size_as_multibyte):
3959 Rename from parse_str_to_multibyte; all uses changed.
3960 Check for integer overflow.
3961 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
3962 since it's now a duplicate of the other. This is more of
3963 a character than a buffer op, so better that it's in character.c.
3964 * fns.c, print.c: Adjust to above changes.
3965
3966 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
3967
3968 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
3969
3970 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3971
3972 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3973 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
3974 (x_clipboard_manager_save): Now static.
3975 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
3976
3977 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3978 (crypto_hash_function): Now static.
3979 Fix pointer signedness problems. Avoid unnecessary initializations.
3980
3981 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
3982
3983 * termhooks.h (Vselection_alist): Make it terminal-local.
3984
3985 * terminal.c (create_terminal): Initialize it.
3986
3987 * xselect.c: Support for clipboard managers.
3988 (Vselection_alist): Move to termhooks.h as terminal-local var.
3989 (LOCAL_SELECTION): New macro.
3990 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
3991 (symbol_to_x_atom): Remove gratuitous arg.
3992 (x_handle_selection_request, lisp_data_to_selection_data)
3993 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
3994 (x_own_selection, x_get_local_selection, x_convert_selection):
3995 New arg, specifying work frame. Use terminal-local Vselection_alist.
3996 (some_frame_on_display): Delete unused function.
3997 (Fx_own_selection_internal, Fx_get_selection_internal)
3998 (Fx_disown_selection_internal, Fx_selection_owner_p)
3999 (Fx_selection_exists_p): New optional frame arg.
4000 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
4001 (x_handle_selection_clear): Don't treat other terminals with the
4002 same keyboard specially. Use the terminal-local Vselection_alist.
4003 (x_clear_frame_selections): Use Frun_hook_with_args.
4004
4005 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
4006
4007 * xterm.h: Add support for those atoms.
4008
4009 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
4010
4011 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
4012 (converted_selections, conversion_fail_tag): New global variables.
4013 (x_selection_request_lisp_error): Free the above.
4014 (x_get_local_selection): Remove unnecessary code.
4015 (x_reply_selection_request): Args changed; handle arbitrary array
4016 of converted selections stored in converted_selections.
4017 Separate the XChangeProperty and SelectionNotify steps.
4018 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
4019 (x_convert_selection): New function.
4020 (x_handle_selection_event): Simplify.
4021 (x_get_foreign_selection): Don't ignore incoming requests while
4022 waiting for an answer; this will fail when we implement
4023 SAVE_TARGETS, and seems unnecessary anyway.
4024 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
4025 (Vx_sent_selection_functions): Doc fix.
4026
4027 2011-05-26 Leo Liu <sdl.web@gmail.com>
4028
4029 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
4030
4031 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4032
4033 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
4034
4035 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
4036 for fringe update if it has periodic bitmap.
4037 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
4038 and fringe_bitmap_periodic_p.
4039
4040 * fringe.c (get_fringe_bitmap_data): New function.
4041 (draw_fringe_bitmap_1, update_window_fringes): Use it.
4042 (update_window_fringes): Record periodicity of fringe bitmap in glyph
4043 row. Mark glyph row for fringe update if periodicity changed.
4044
4045 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
4046 for fringe update unless it has periodic bitmap.
4047
4048 2011-05-25 Kenichi Handa <handa@m17n.org>
4049
4050 * xdisp.c (get_next_display_element): Set correct it->face_id for
4051 a static composition.
4052
4053 2011-05-24 Leo Liu <sdl.web@gmail.com>
4054
4055 * deps.mk (fns.o):
4056 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
4057
4058 * fns.c (crypto_hash_function, Fsha1): New function.
4059 (Fmd5): Use crypto_hash_function.
4060 (syms_of_fns): Add Ssha1.
4061
4062 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
4063
4064 * gnutls.c: Remove unused macros.
4065 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
4066 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
4067 Remove macros that are defined and never used.
4068 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
4069
4070 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
4071
4072 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
4073 (Fx_get_selection_internal): Minor cleanup.
4074 (Fx_own_selection_internal): Rename arguments for consistency with
4075 select.el.
4076
4077 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
4078
4079 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
4080
4081 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
4082
4083 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
4084
4085 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4086
4087 * dispnew.c (scrolling_window): Don't exclude the case that the
4088 last enabled row in the desired matrix touches the bottom boundary.
4089
4090 2011-05-21 Glenn Morris <rgm@gnu.org>
4091
4092 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
4093 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
4094 and add some more files.
4095
4096 2011-05-20 Eli Zaretskii <eliz@gnu.org>
4097
4098 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
4099 report_file_error introduced by the change from 2011-05-07.
4100
4101 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
4102
4103 * systime.h (Time): Define only if emacs is defined.
4104 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
4105 where the include path doesn't have X11/X.h by default. See
4106 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
4107
4108 2011-05-20 Kenichi Handa <handa@m17n.org>
4109
4110 * composite.c (find_automatic_composition): Fix previous change.
4111
4112 2011-05-20 Glenn Morris <rgm@gnu.org>
4113
4114 * lisp.mk: New file, split from Makefile.in.
4115 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
4116 (shortlisp): Remove.
4117 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
4118
4119 2011-05-19 Glenn Morris <rgm@gnu.org>
4120
4121 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
4122 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
4123 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
4124 (lisp): Set the order to that of loadup.el.
4125 (shortlisp): Make it a copy of $lisp.
4126 (SOME_MACHINE_LISP): Remove.
4127 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
4128 Use just $shortlisp, not $SOME_MACHINE_LISP too.
4129
4130 2011-05-18 Kenichi Handa <handa@m17n.org>
4131
4132 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
4133 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
4134 (find_automatic_composition): Mostly rewrite for efficiency.
4135
4136 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
4137
4138 * makefile.w32-in: Update dependencies.
4139
4140 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
4141
4142 * menu.c: Include limits.h (fixes the MS-Windows build broken by
4143 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
4144
4145 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
4146
4147 Fix some integer overflow issues, such as string length overflow.
4148
4149 * insdel.c (count_size_as_multibyte): Check for string overflow.
4150
4151 * character.c (lisp_string_width): Check for string overflow.
4152 Use EMACS_INT, not int, for string indexes and lengths; in
4153 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
4154 the resulting string length overflows an EMACS_INT; instead,
4155 report a string overflow if no precision given. When checking for
4156 precision exhaustion, use a check that cannot possibly have
4157 integer overflow. (Bug#8675)
4158 * character.h (lisp_string_width): Adjust to new signature.
4159
4160 * alloc.c (string_overflow): New function.
4161 (Fmake_string): Use it. This doesn't change behavior, but saves
4162 a few bytes and will simplify future changes.
4163 * character.c (string_escape_byte8): Likewise.
4164 * lisp.h (string_overflow): New decl.
4165
4166 Fixups, following up to the user-interface timestamp change.
4167 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
4168 for UI timestamps, instead of unsigned long.
4169 * msdos.c (mouse_get_pos): Likewise.
4170 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
4171 * w32gui.h (Time): Define by including "systime.h" rather than by
4172 declaring it ourselves. (Bug#8664)
4173
4174 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
4175 * image.c (clear_image_cache): Likewise.
4176
4177 * term.c (term_mouse_position): Don't assume time_t wraparound.
4178
4179 Be more systematic about user-interface timestamps.
4180 Before, the code sometimes used 'Time', sometimes 'unsigned long',
4181 and sometimes 'EMACS_UINT', to represent these timestamps.
4182 This change causes it to use 'Time' uniformly, as that's what X uses.
4183 This makes the code easier to follow, and makes it easier to catch
4184 integer overflow bugs such as Bug#8664.
4185 * frame.c (Fmouse_position, Fmouse_pixel_position):
4186 Use Time, not unsigned long, for user-interface timestamps.
4187 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
4188 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
4189 * keyboard.h (last_event_timestamp): Likewise.
4190 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
4191 * menu.h (xmenu_show): Likewise.
4192 * term.c (term_mouse_position): Likewise.
4193 * termhooks.h (struct input_event.timestamp): Likewise.
4194 (struct terminal.mouse_position_hook): Likewise.
4195 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
4196 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
4197 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
4198 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
4199 what it was before.
4200 * menu.h, termhooks.h: Include "systime.h", for Time.
4201
4202 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
4203 Don't assume that the difference between two unsigned long values
4204 can fit into an integer. At this point, we know button_down_time
4205 <= event->timestamp, so the difference must be nonnegative, so
4206 there's no need to cast the result if double-click-time is
4207 nonnegative, as it should be; check that it's nonnegative, just in
4208 case. This bug is triggered when events are more than 2**31 ms
4209 apart (about 25 days). (Bug#8664)
4210
4211 * xselect.c (last_event_timestamp): Remove duplicate decl.
4212 (x_own_selection): Remove needless cast to unsigned long.
4213
4214 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
4215 that always fit in int. Use a sentinel instead of a counter, to
4216 avoid a temp and to allay GCC's concerns about possible int overflow.
4217 * frame.h (struct frame): Use int for menu_bar_items_used
4218 instead of EMACS_INT, since it always fits in int.
4219
4220 * menu.c (grow_menu_items): Check for int overflow.
4221
4222 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
4223
4224 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
4225 Before, the code was not consistent. These values cannot exceed
4226 2**31 - 1 so there's no need to make them unsigned.
4227 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
4228 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
4229 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
4230 as modifiers.
4231 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
4232
4233 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
4234 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
4235 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
4236 presumably because the widths might not match.
4237
4238 * window.c (size_window): Avoid needless test at loop start.
4239
4240 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
4241
4242 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
4243
4244 2011-05-12 Drew Adams <drew.adams@oracle.com>
4245
4246 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
4247
4248 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4249
4250 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
4251 `width' to `bar_area_x' and `bar_area_width', respectively.
4252 (x_scroll_run): Take account of fringe background extension.
4253
4254 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
4255 Rename local vars `left' and `width' to `bar_area_x' and
4256 `bar_area_width', respectively.
4257 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
4258 background extension.
4259
4260 2011-05-10 Jim Meyering <meyering@redhat.com>
4261
4262 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
4263
4264 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
4265
4266 * image.c (Finit_image_library): Return t for built-in image types,
4267 like pbm and xbm. (Bug#8640)
4268
4269 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
4270
4271 * w32menu.c (set_frame_menubar): Fix submenu allocation.
4272
4273 2011-05-07 Eli Zaretskii <eliz@gnu.org>
4274
4275 * w32console.c (Fset_screen_color): Doc fix.
4276 (Fget_screen_color): New function.
4277 (syms_of_ntterm): Defsubr it.
4278
4279 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
4280 unlink the temporary file if Fcall_process didn't create it in the
4281 first place.
4282 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
4283 child process will be redirected to a file specified with `:file'.
4284 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
4285 cue to call_process_cleanup not to close that handle.
4286
4287 2011-05-07 Ben Key <bkey76@gmail.com>
4288
4289 * makefile.w32-in: The bootstrap-temacs rule now makes use of
4290 one of two shell specific rules, either bootstrap-temacs-CMD or
4291 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
4292 to the previous implementation of the bootstrap-temacs rule.
4293 The bootstrap-temacs-CMD rule is similar to the previous
4294 implementation of the bootstrap-temacs rule except that it
4295 makes use of the ESC_CFLAGS variable instead of the CFLAGS
4296 variable.
4297
4298 These changes, along with some changes to nt/configure.bat,
4299 nt/gmake.defs, and nt/nmake.defs, are required to extend my
4300 earlier fix to add support for --cflags and --ldflags options
4301 that include quotes so that it works whether make uses cmd or
4302 sh as the shell.
4303
4304 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
4305
4306 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
4307 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
4308 is a constant.
4309 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
4310 a string. Handle both cases.
4311 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
4312 (Fdbus_register_method): Use Qinvalid_function.
4313
4314 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
4315
4316 * makefile.w32-in: Update dependencies.
4317 (LISP_H): Add inttypes.h and stdin.h.
4318 (PROCESS_H): Add unistd.h.
4319
4320 2011-05-06 Eli Zaretskii <eliz@gnu.org>
4321
4322 * lread.c: Include limits.h (fixes the MS-Windows build broken by
4323 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
4324
4325 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
4326
4327 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
4328
4329 * term.c (vfatal): Remove stray call to va_end.
4330 It's not needed and the C Standard doesn't allow it here anyway.
4331
4332 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
4333 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
4334
4335 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
4336 bytes.
4337
4338 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
4339
4340 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
4341
4342 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
4343
4344 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
4345
4346 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
4347
4348 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
4349 * charset.c (Fdefine_charset_internal): Don't initialize
4350 charset.code_space[15]. The value was garbage, on hosts with
4351 32-bit int (Bug#8600).
4352
4353 * lread.c (read_integer): Be more consistent with string-to-number.
4354 Use string_to_number to do the actual conversion; this avoids
4355 rounding errors and fixes some other screwups. Without this fix,
4356 for example, #x1fffffffffffffff was misread as -2305843009213693952.
4357 (digit_to_number): Move earlier, for benefit of read_integer.
4358 Return -1 if the digit is out of range for the base, -2 if it is
4359 not a digit in any supported base. (Bug#8602)
4360
4361 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
4362
4363 * dispnew.c (scrolling_window): Return 1 if we scrolled,
4364 to match comment at start of function. This also removes a
4365 GCC warning about overflow in a 32+64-bit port.
4366
4367 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
4368
4369 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
4370 Reported by Stefan Monnier in
4371 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
4372 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
4373 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
4374
4375 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
4376 (EMACS_UINTPTR): Likewise, with uintptr_t.
4377
4378 * lisp.h: Prefer 64-bit EMACS_INT if available.
4379 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
4380 on 32-bit hosts that have 64-bit int, so that they can access
4381 large files.
4382 However, temporarily disable this change unless the temporary
4383 symbol WIDE_EMACS_INT is defined.
4384
4385 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
4386
4387 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
4388 This removes an assumption that EMACS_INT and long are the same
4389 width as pointers. The assumption is true for Emacs porting targets
4390 now, but we want to make other targets possible.
4391 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
4392 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
4393 In the rest of the code, change types of integers that hold casted
4394 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
4395 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
4396 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
4397 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
4398 No need to cast type when ORing.
4399 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
4400 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
4401 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
4402 assume EMACS_INT is the same width as char *.
4403 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
4404 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
4405 Remove no-longer-needed casts.
4406 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
4407 (xg_tool_bar_help_callback, xg_make_tool_item):
4408 Use EMACS_INTPTR to hold an integer
4409 that will be cast to void *; this can avoid a GCC warning
4410 if EMACS_INT is not the same width as void *.
4411 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
4412 * xdisp.c (display_echo_area_1, resize_mini_window_1):
4413 (current_message_1, set_message_1):
4414 Use a local to convert to proper width without a cast.
4415 * xmenu.c (dialog_selection_callback): Likewise.
4416
4417 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
4418 Also, don't assume VALBITS / RAND_BITS is less than 5,
4419 and don't rely on undefined behavior when shifting a 1 left into
4420 the sign bit.
4421 * lisp.h (get_random): Change signature to match.
4422
4423 * lread.c (hash_string): Use size_t, not int, for hash computation.
4424 Normally we prefer signed values; but hashing is special, because
4425 it's better to use unsigned division on hash table sizes so that
4426 the remainder is nonnegative. Also, size_t is the natural width
4427 for hashing into memory. The previous code used 'int', which doesn't
4428 retain enough info to hash well into very large tables.
4429 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
4430
4431 * dbusbind.c: Don't possibly lose pointer info when converting.
4432 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
4433 Use XPNTR rather than XHASH, so that the high-order bits of
4434 the pointer aren't lost when converting through void *.
4435
4436 * eval.c (Fautoload): Don't double-shift a pointer.
4437
4438 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
4439
4440 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
4441
4442 * gnutls.c (DEF_GNUTLS_FN):
4443 * image.c (DEF_IMGLIB_FN): Make function pointers static.
4444
4445 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
4446
4447 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
4448 marker. (Bug#8610)
4449
4450 2011-05-05 Eli Zaretskii <eliz@gnu.org>
4451

4454
4455 2011-05-05 Chong Yidong <cyd@stupidchicken.com>

4467 Update dependencies.
4468
4469 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4470
4471 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
4472 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
4473 Remove unused parameter `fildes'.
4474 * process.c (read_process_output, send_process): Don't pass it.
4475
4476 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4477
4478 Fix previous change: the library cache is defined in w32.c.
4479 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
4480 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
4481
4482 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
4483
4484 Implement dynamic loading of GnuTLS on Windows.
4485
4486 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
4487 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
4488 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
4489 Declare.
4490
4491 * gnutls.c (Qgnutls_dll): Define.
4492 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
4493 (gnutls_*): Declare function pointers.
4494 (init_gnutls_functions): New function to initialize function pointers.
4495 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
4496 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
4497 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
4498 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
4499 (emacs_gnutls_write, emacs_gnutls_read)
4500 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
4501 (Fgnutls_available_p): New function.
4502 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

4511
4512 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
4513
4514 * w32.c (QCloaded_from, Vlibrary_cache): Define.
4515 (w32_delayed_load): Move from image.c. When loading a library, record
4516 its filename in the :loaded-from property of the library id.
4517 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
4518 Initialize and staticpro them.
4519 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
4520
4521 * process.c: Include lisp.h before w32.h, not after.
4522 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
4523 instead of gnutls_record_check_pending.
4524
4525 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.

4549 (Qgnutls_bootprop_callbacks, Qgnutls_bootprop_loglevel)
4550 (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags)
4551 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
4552 (Qgnutls_bootprop_callbacks_verify): Make static.
4553
4554 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
4555
4556 * callproc.c: Indentation fixup.
4557
4558 * sysdep.c (wait_for_termination_1): Make static.
4559 (wait_for_termination, interruptible_wait_for_termination):
4560 Move after wait_for_termination_1.
4561
4562 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
4563
4564 * sysdep.c (interruptible_wait_for_termination): New function
4565 which is like wait_for_termination, but allows keyboard
4566 interruptions.
4567
4568 * callproc.c (Fcall_process): Add (:file "file") as an option for
4569 the STDOUT buffer.
4570 (Fcall_process_region): Ditto.
4571
4572 2011-04-30 Eli Zaretskii <eliz@gnu.org>
4573
4574 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
4575 rather than `XVECTOR (FOO)->size'.
4576
4577 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
4578 inttypes.h, as a gnulib replacement is used if it not available in
4579 system headers.
4580
4581 2011-04-21 Eli Zaretskii <eliz@gnu.org>
4582
4583 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

4585 of MOST_POSITIVE_FIXNUM. (Bug#8528)
4586
4587 * coding.c (coding_alloc_by_realloc): Error out if destination
4588 will grow beyond MOST_POSITIVE_FIXNUM.
4589 (decode_coding_emacs_mule): Abort if there isn't enough place in
4590 charbuf for the composition carryover bytes. Reserve an extra
4591 space for up to 2 characters produced in a loop.
4592 (decode_coding_iso_2022): Abort if there isn't enough place in
4593 charbuf for the composition carryover bytes.
4594
4595 2011-04-21 Eli Zaretskii <eliz@gnu.org>
4596
4597 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
4598 aborting when %lld or %lll format is passed.
4599 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
4600 %llo or %llx format is passed. (Bug#8545)
4601
4602 * window.c (window_scroll_line_based): Use a marker instead of
4603 simple variables to record original value of point. (Bug#7952)
4604
4605 * doprnt.c (doprnt): Fix the case where a multibyte sequence
4606 produced by %s or %c overflows available buffer space. (Bug#8545)
4607
4608 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
4609
4610 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
4611 (SIZE_MAX): Move defn after all includes, as they might #define it.
4612
4613 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4614
4615 * w32.c (init_environment): Warn about defaulting HOME to C:\.
4616
4617 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4618
4619 * keyboard.c (Qdelayed_warnings_hook): Define.
4620 (command_loop_1): Run `delayed-warnings-hook'
4621 if Vdelayed_warnings_list is non-nil.
4622 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
4623 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
4624
4625 2011-04-28 Eli Zaretskii <eliz@gnu.org>
4626
4627 * doprnt.c (doprnt): Don't return value smaller than the buffer
4628 size if the message was truncated. (Bug#8545).
4629
4630 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
4631
4632 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
4633 (Fx_window_property): #if-0 the whole functions, not just the bodies.
4634
4635 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
4636
4637 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
4638
4639 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
4640
4641 * makefile.w32-in: Update dependencies.
4642
4643 2011-04-27 Eli Zaretskii <eliz@gnu.org>
4644
4645 Improve `doprnt' and its usage. (Bug#8545)
4646 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
4647 `format_end'. Remove support for %l as a conversion specifier.
4648 Don't use xrealloc. Improve diagnostics when the %l size modifier
4649 is used. Update the commentary.
4650
4651 * eval.c (verror): Simplify calculation of size_t.
4652
4653 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
4654 messages.
4655
4656 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
4657
4658 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
4659 change.
4660
4661 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
4662
4663 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
4664 This makes this file independent of the recent pseudovector change.
4665
4666 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
4667
4668 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
4669
4670 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
4671 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
4672 Remove unused local.
4673 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
4674
4675 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
4676 GCC 4.6.0 optimizes based on type-based alias analysis.
4677 For example, if b is of type struct buffer * and v of type struct
4678 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
4679 != &v->size, and therefore "v->size = 1; b->size = 2; return
4680 v->size;" must therefore return 1. This assumption is incorrect
4681 for Emacs, since it type-puns struct Lisp_Vector * with many other
4682 types. To fix this problem, this patch adds a new type struct
4683 vectorlike_header that documents the constraints on layout of vectors
4684 and pseudovectors, and helps optimizing compilers not get fooled
4685 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
4686 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
4687 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
4688 the size member.
4689 (XSETPVECTYPE): Rewrite in terms of new macro.
4690 (XSETPVECTYPESIZE): New macro, specifying both type and size.
4691 This is a bit clearer, and further avoids the possibility of
4692 undesirable aliasing.
4693 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
4694 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
4695 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
4696 since Lisp_Subr is a special case (no "next" field).
4697 (ASIZE): Now uses header.size rather than size.
4698 All previous uses of XVECTOR (foo)->size replaced to use this macro,
4699 to avoid the hassle of writing XVECTOR (foo)->header.size.
4700 (struct vectorlike_header): New type.
4701 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
4702 object, to help avoid aliasing.
4703 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
4704 (SUBRP): Likewise, since Lisp_Subr is a special case.
4705 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
4706 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
4707 (struct Lisp_Hash_Table): Combine first two members into a single
4708 struct vectorlike_header member. All uses of "size" and "next" members
4709 changed to be "header.size" and "header.next".
4710 * buffer.h (struct buffer): Likewise.
4711 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
4712 * frame.h (struct frame): Likewise.
4713 * process.h (struct Lisp_Process): Likewise.
4714 * termhooks.h (struct terminal): Likewise.
4715 * window.c (struct save_window_data, struct saved_window): Likewise.
4716 * window.h (struct window): Likewise.
4717 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
4718 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
4719 * buffer.c (init_buffer_once): Likewise.
4720 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
4721 special case.
4722 * process.c (Fformat_network_address): Use local var for size,
4723 for brevity.
4724
4725 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
4726
4727 Make the Lisp reader and string-to-float more consistent (Bug#8525)
4728 * data.c (atof): Remove decl; no longer used or needed.
4729 (digit_to_number): Move to lread.c.
4730 (Fstring_to_number): Use new string_to_number function, to be
4731 consistent with how the Lisp reader treats infinities and NaNs.
4732 Do not assume that floating-point numbers represent EMACS_INT
4733 without losing information; this is not true on most 64-bit hosts.
4734 Avoid double-rounding errors, by insisting on integers when
4735 parsing non-base-10 numbers, as the documentation specifies.
4736 * lisp.h (string_to_number): New decl, replacing ...
4737 (isfloat_string): Remove.
4738 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
4739 (read1): Do not accept +. and -. as integers; this
4740 appears to have been a coding error. Similarly, do not accept
4741 strings like +-1e0 as floating point numbers. Do not report
4742 overflow for integer overflows unless the base is not 10 which
4743 means we have no simple and reliable way to continue.
4744 Break out the floating-point parsing into a new
4745 function string_to_number, so that Fstring_to_number parses
4746 floating point numbers consistently with the Lisp reader.
4747 (digit_to_number): Move here from data.c. Make it static inline.
4748 (E_CHAR, EXP_INT): Remove, replacing with ...
4749 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
4750 (string_to_number): New function, replacing isfloat_string.
4751 This function checks for valid syntax and produces the resulting
4752 Lisp float number too. Rework it so that string-to-number
4753 no longer mishandles examples like "1.0e+". Use strtoumax,
4754 so that overflow for non-base-10 numbers is reported only when
4755 there's no portable and simple way to convert to floating point.
4756
4757 * textprop.c (set_text_properties_1): Rewrite for clarity,
4758 and to avoid GCC warning about integer overflow.
4759
4760 * intervals.h (struct interval): Use EMACS_INT for members
4761 where EMACS_UINT might cause problems. See
4762 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
4763 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
4764 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
4765 All uses changed.
4766 (offset_intervals): Tell GCC not to worry about length overflow
4767 when negating a negative length.
4768
4769 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
4770 (overrun_check_free): Likewise.
4771
4772 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
4773 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
4774 word size.
4775
4776 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4777 (gnutls_make_error): Rename local to avoid shadowing.
4778 (gnutls_emacs_global_deinit): ifdef out; not used.
4779 (Fgnutls_boot): Use const for pointer to readonly storage.
4780 Comment out unused local. Fix pointer signedness problems.
4781
4782 * lread.c (openp): Don't stuff size_t into an 'int'.
4783 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
4784 about possible signed overflow.
4785
4786 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
4787 (GDK_KEY_g): Don't define if already defined.
4788 (xg_prepare_tooltip): Avoid pointer signedness problem.
4789 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
4790
4791 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
4792 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
4793
4794 * xfns.c (Fx_window_property): Simplify a bit,
4795 to make a bit faster and to avoid GCC 4.6.0 warning.
4796 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
4797
4798 * fns.c (internal_equal): Don't assume size_t fits in int.
4799
4800 * alloc.c (compact_small_strings): Tighten assertion a little.
4801
4802 Replace pEd with more-general pI, and fix some printf arg casts.
4803 * lisp.h (pI): New macro, generalizing old pEd macro to other
4804 conversion specifiers. For example, use "...%"pI"d..." rather
4805 than "...%"pEd"...".
4806 (pEd): Remove. All uses replaced with similar uses of pI.
4807 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
4808 * alloc.c (check_pure_size): Don't overflow by converting size to int.
4809 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
4810 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
4811 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
4812 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
4813 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
4814 64-bit hosts.
4815 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
4816 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
4817 * print.c (safe_debug_print, print_object): Likewise.
4818 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
4819 to int.
4820 Use pI instead of if-then-else-abort. Use %p to avoid casts,
4821 avoiding the 0 flag, which is not portable.
4822 * process.c (Fmake_network_process): Use pI to avoid cast.
4823 * region-cache.c (pp_cache): Likewise.
4824 * xdisp.c (decode_mode_spec): Likewise.
4825 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
4826 behavior on 64-bit hosts with printf arg.
4827 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
4828 (x_stop_queuing_selection_requests): Likewise.
4829 (x_get_window_property): Don't truncate byte count to an 'int'
4830 when tracing.
4831
4832 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
4833 here, since it parses constructs like leading '-' and spaces,
4834 which are not wanted; and it overflows with large numbers.
4835 Instead, simply match F[0-9]+, which is what is wanted anyway.
4836
4837 * alloc.c: Remove unportable assumptions about struct layout.
4838 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
4839 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
4840 (allocate_vectorlike, make_pure_vector): Use the new macros,
4841 plus offsetof, to remove unportable assumptions about struct layout.
4842 These assumptions hold on all porting targets that I know of, but
4843 they are not guaranteed, they're easy to remove, and removing them
4844 makes further changes easier.
4845
4846 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
4847 This doesn't fix a bug but makes the code clearer.
4848 (string_overrun_cookie): Now const. Use initializers that
4849 don't formally overflow signed char, to avoid warnings.
4850 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
4851 can cause Emacs to crash when string overrun checking is enabled.
4852 (allocate_buffer): Don't assume sizeof (struct buffer) is a
4853 multiple of sizeof (EMACS_INT); it need not be, if
4854 alignof(EMACS_INT) < sizeof (EMACS_INT).
4855 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
4856
4857 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
4858
4859 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.

4862
4863 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
4864 supposed to be handshaking. (Bug#8556)
4865 Reported by Paul Eggert <eggert@cs.ucla.edu>.
4866
4867 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
4868
4869 * lisp.h (Qdebug): List symbol.
4870 * eval.c (Qdebug): Restore global linkage.
4871 * keyboard.c (debug-on-event): New variable.
4872 (handle_user_signal): Break into debugger when debug-on-event
4873 matches the current signal symbol.
4874
4875 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
4876
4877 * alloc.c (check_sblock, check_string_bytes)
4878 (check_string_free_list): Convert to standard C.
4879
4880 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
4881
4882 * w32.c (emacs_gnutls_push): Fix typo.
4883
4884 2011-04-25 Eli Zaretskii <eliz@gnu.org>
4885
4886 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
4887 "cast to pointer from integer of different size".
4888
4889 Improve doprnt and its use in verror. (Bug#8545)
4890 * doprnt.c (doprnt): Document the set of format control sequences
4891 supported by the function. Use SAFE_ALLOCA instead of always
4892 using `alloca'.
4893
4894 * eval.c (verror): Don't limit the buffer size at size_max-1, that
4895 is one byte too soon. Don't use xrealloc; instead xfree and
4896 xmalloc anew.
4897
4898 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
4899
4900 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
4901 callbacks stage.
4902
4903 * gnutls.c: Renamed global_initialized to
4904 gnutls_global_initialized. Added internals for the
4905 :verify-hostname-error, :verify-error, and :verify-flags
4906 parameters of `gnutls-boot' and documented those parameters in the
4907 docstring. Start callback support.
4908 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
4909 unless a fatal error occurred. Call gnutls_alert_send_appropriate
4910 on error. Return error code.
4911 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
4912 (emacs_gnutls_read): Likewise.
4913 (Fgnutls_boot): Return handshake error code.
4914 (emacs_gnutls_handle_error): New function.

4926 buffered some data internally if no FDs are set for TLS
4927 connections.
4928
4929 * makefile.w32-in (OBJ2): Add gnutls.$(O).

4934
4935 * xdisp.c (handle_single_display_spec): Rename the
4936 display_replaced_before_p argument into display_replaced_p, to
4937 make it consistent with the commentary. Fix typos in the
4938 commentary.
4939
4940 * textprop.c (syms_of_textprop): Remove dead code.
4941 (copy_text_properties): Delete obsolete commentary about an
4942 interface that was deleted long ago. Fix typos in the description
4943 of arguments.
4944

4946 to changes in oldXMenu/XMenu.h from 2011-04-16.
4947 <menu_help_message, prev_menu_help_message>: Constify.
4948 (IT_menu_make_room): menu->help_text is now `const char **';
4949 adjust.
4950
4951 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
4952 to changes in oldXMenu/XMenu.h from 2011-04-16.

4954
4955 * xfaces.c <Qunspecified>: Make extern again.
4956
4957 * syntax.c: Include sys/types.h before including regex.h, as
4958 required by Posix.
4959
4960 * doc.c (get_doc_string): Improve the format passed to `error'.
4961
4962 * doprnt.c (doprnt): Improve commentary.
4963
4964 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
4965
4966 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
4967 them with etags.
4968
4969 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
4970 changes in globals.h immediately force recompilation.
4971 (TAGS): Depend on $(CURDIR)/m/intel386.h and
4972 $(CURDIR)/s/ms-w32.h.
4973 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
4974
4975 * character.c (Fchar_direction): Function deleted.
4976 (syms_of_character): Don't defsubr it.
4977 <char-direction-table>: Deleted.
4978
4979 2011-04-23 Eli Zaretskii <eliz@gnu.org>
4980
4981 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
4982 * doprnt.c: Include limits.h.
4983 (SIZE_MAX): New macro.
4984 (doprnt): Return a size_t value. 2nd arg is now size_t.
4985 Many local variables are now size_t instead of int or unsigned.
4986 Improve overflow protection. Support `l' modifier for integer
4987 conversions. Support %l conversion. Don't assume an EMACS_INT
4988 argument for integer conversions and for %c.
4989
4990 * lisp.h (doprnt): Restore prototype.
4991
4992 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
4993 $(SRC)/character.h.
4994
4995 * Makefile.in (base_obj): Add back doprnt.o.
4996
4997 * deps.mk (doprnt.o): Add back prerequisites.
4998 (callint.o): Depend on character.h.
4999
5000 * eval.c (internal_lisp_condition_case): Include the handler
5001 representation in the error message.
5002 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
5003 when breaking from the loop.
5004
5005 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
5006
5007 * callint.c (Fcall_interactively): When displaying error message
5008 about invalid control letter, pass the character's codepoint, not
5009 a pointer to its multibyte form. Improve display of the character

5438 * xfaces.c (face_at_string_position):
5439 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
5440 since 0 is always ASCII.

5443
5444 * fileio.c: Make symbols static if they're not exported.

5463 * editfns.c, lisp.h (get_operating_system_release): Remove.
5464 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
5465 worth the hassle of breaking this out.
5466
5467 * xterm.c: Make symbols static if they're not exported.
5468 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

5571 * buffer.c (buffer_count): Remove unused var.
5572
5573 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
5574 so that it's not optimized away.
5575 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
5576 * dispextern.h (bidi_dump_cached_states): Remove, since it's
5577 exported only to the debugger.
5578
5579 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
5580 * atimer.h (run_all_atimers): Remove; not exported.
5581
5582 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
5583 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
5584 was inaccessible from Lisp.
5585 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
5586 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
5587
5588 alloc.c: Import and export fewer symbols, and remove unused items.
5589 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
5590 is defined.
5591 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
5592 it's not optimized away by whole-program optimization.
5593 (message_enable_multibyte, free_misc): Remove.
5594 (catchlist, handlerlist, mark_backtrace):
5595 Declare only if BYTE_MARK_STACK.

5604 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
5605 (mark_backtrace): Define only if BYTE_MARK_STACK.
5606 * xdisp.c (message_enable_multibyte): Now static.
5607
5608 Declare Lisp_Object Q* variables to be 'static' if not exported.
5609 This makes it easier for human readers (and static analyzers)
5610 to see whether these variables are used from other modules.
5611 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
5612 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
5613 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

5621 Remove decls of unexported vars.
5622 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
5623
5624 * lisp.h (DEFINE_FUNC): Make sname 'static'.
5625
5626 Make Emacs functions such as Fatom 'static' by default.
5627 This makes it easier for human readers (and static analyzers)
5628 to see whether these functions can be called from other modules.
5629 DEFUN now defines a static function. To make the function external
5630 so that it can be used in other C modules, use the new macro DEFUE.
5631 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
5632 (Finit_image_library):
5633 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
5634 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
5635 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
5636 Remove decls, since these functions are now static.
5637 (Funintern, Fget_internal_run_time): New decls, since these functions
5638 were already external.
5639
5640 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
5641 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

5646 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
5647 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
5648 Mark functions with DEFUE instead of DEFUN,
5649 if they are used in other modules.
5650 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
5651 decls for now-static functions.
5652 * buffer.h (Fdelete_overlay): Remove decl.
5653 * callproc.c (Fgetenv_internal): Mark as internal.
5654 * composite.c (Fremove_list_of_text_properties): Remove decl.

5665 (Fremove_list_of_text_properties): Remove decls.
5666 * keyboard.c (Fthis_command_keys): Remove decl.
5667 (Fcommand_execute): New forward static decl.
5668 * keymap.c (Flookup_key): New forward static decl.
5669 (Fcopy_keymap): Now static.
5670 * keymap.h (Flookup_key): Remove decl.
5671 * process.c (Fget_process): New forward static decl.
5672 (Fprocess_datagram_address): Mark as internal.

5677 Now internal.
5678 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
5679 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
5680
5681 * editfns.c (Fformat): Remove unreachable code.
5682
5683 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
5684
5685 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
5686 change. (Bug#8496)
5687
5688 2011-04-13 Eli Zaretskii <eliz@gnu.org>
5689
5690 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
5691 when at ZV. (Bug#8487)
5692
5693 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
5694
5695 * charset.c (Fclear_charset_maps): Use xfree instead of free.
5696 (Bug#8437)
5697 * keyboard.c (parse_tool_bar_item): Likewise.
5698 * sound.c (sound_cleanup, alsa_close): Likewise.
5699 * termcap.c (tgetent): Likewise.
5700 * xfns.c (x_default_font_parameter): Likewise.
5701 * xsettings.c (read_and_apply_settings): Likewise.
5702
5703 * alloc.c (overrun_check_malloc, overrun_check_realloc)
5704 (overrun_check_free): Protoize.
5705
5706 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
5707
5708 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
5709 since callers should never pass a negative size.
5710 Change the signature to match that of plain 'read' and 'write'; see
5711 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
5712 * lisp.h: Update prototypes of emacs_write and emacs_read.
5713
5714 2011-04-11 Eli Zaretskii <eliz@gnu.org>
5715
5716 * xdisp.c (redisplay_window): Don't try to determine the character
5717 position of the scroll margin if the window start point w->startp
5718 is outside the buffer's accessible region. (Bug#8468)
5719
5720 2011-04-10 Eli Zaretskii <eliz@gnu.org>
5721
5722 Fix write-region and its subroutines for buffers > 2GB.
5723 * fileio.c (a_write, e_write): Modify declaration of arguments and
5724 local variables to support buffers larger than 2GB.
5725 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
5726
5727 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
5728 argument, local variables, and return value.
5729
5730 * lisp.h: Update prototypes of emacs_write and emacs_read.
5731
5732 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
5733
5734 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
5735
5736 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
5737
5738 Fix more problems found by GCC 4.6.0's static checks.
5739
5740 * xdisp.c (vmessage): Use a better test for character truncation.
5741
5742 * charset.c (load_charset_map): <, not <=, for optimization,
5743 and to avoid potential problems with integer overflow.
5744 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
5745 * casetab.c (set_identity, shuffle): Likewise.
5746 * editfns.c (Fformat): Likewise.
5747 * syntax.c (skip_chars): Likewise.
5748
5749 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
5750 This also lets GCC 4.6.0 generate slightly better loop code.
5751
5752 * callint.c (Fcall_interactively): <, not <=, for optimization.
5753 (Fcall_interactively): Count the number of arguments produced,
5754 not the number of arguments given. This is simpler and lets GCC
5755 4.6.0 generate slightly better code.
5756
5757 * ftfont.c: Distingish more carefully between FcChar8 and char.
5758 The previous code passed unsigned char * to a functions like
5759 strlen and xstrcasecmp that expect char *, which does not
5760 conform to the C standard.
5761 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
5762 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
5763 char * when the C standard requires it.
5764
5765 * keyboard.c (read_char): Remove unused var.
5766
5767 * eval.c: Port to Windows vsnprintf (Bug#8435).
5768 Include <limits.h>.
5769 (SIZE_MAX): Define if the headers do not.
5770 (verror): Do not give up if vsnprintf returns a negative count.
5771 Instead, grow the buffer. This ports to Windows vsnprintf, which
5772 does not conform to C99. Problem reported by Eli Zaretskii.
5773 Also, simplify the allocation scheme, by avoiding the need for
5774 calling realloc, and removing the ALLOCATED variable.
5775
5776 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
5777
5778 Remove invocations of doprnt, as Emacs now uses vsnprintf.
5779 But keep the doprint source code for now, as we might revamp it
5780 and use it again (Bug#8435).
5781 * lisp.h (doprnt): Remove.
5782 * Makefile.in (base_obj): Remove doprnt.o.
5783 * deps.mk (doprnt.o): Remove.
5784
5785 error: Print 32- and 64-bit integers portably (Bug#8435).
5786 Without this change, on typical 64-bit hosts error ("...%d...", N)
5787 was used to print both 32- and 64-bit integers N, which relied on
5788 undefined behavior.
5789 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
5790 New macro.
5791 * lisp.h (error, verror): Mark as printf-like functions.
5792 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
5793 Report overflow in size calculations when allocating printf buffer.
5794 Do not truncate output string at its first null byte.
5795 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
5796 Truncate the output at a character boundary, since vsnprintf does not
5797 do that.
5798 * charset.c (check_iso_charset_parameter): Convert internal
5799 character to string before calling 'error', since %c now has the
5800 printf meaning.
5801 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
5802 overflow when computing char to be passed to 'error'. Do not
5803 pass Lisp_Object to 'error'; pass the integer instead.
5804 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
5805 formatted with plain %d.
5806
5807 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
5808
5809 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
5810
5811 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
5812
5813 * xterm.c (x_catch_errors): Remove duplicate declaration.
5814
5815 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
5816
5817 * xdisp.c, lisp.h (message_nolog): Remove; unused.
5818
5819 2011-04-10 Jim Meyering <meyering@redhat.com>
5820
5821 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
5822 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
5823 return ssize_t not "int", and use size_t as the buffer length.

5991
5992 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
5993 (font_score): Avoid potential overflow in diff calculation.
5994

5998 * eval.c (funcall_lambda): Rename local to avoid shadowing.
5999
6000 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.

6002 can always succeed if overflow has undefined behavior.
6003
6004 * search.c (boyer_moore, wordify): Remove vars set but not used.
6005 (wordify): Omit three unnecessary tests.
6006

6036 that are set but not used.
6037
6038 * xfns.c (make_invisible_cursor): Don't return garbage
6039 if XCreateBitmapFromData fails (Bug#8410).
6040
6041 * xselect.c (x_get_local_selection, x_handle_property_notify):
6042 Remove vars that are set but not used.

6054 (map_tty_color) [!defined MSDOS]: Likewise.
6055

6057
6058 * coding.c: Remove vars that are set but not used.
6059 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
6060 All callers changed.

6071 The gnulib version avoids calling malloc in the usual case,
6072 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
6073 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
6074 * filelock.c (current_lock_owner): Likewise.
6075 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
6076 * sysdep.c: Include allocator.h, careadlinkat.h.
6077 (emacs_no_realloc_allocator): New static constant.
6078 (emacs_readlink): New function.
6079 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

6085 first non-nil return value).
6086
6087 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
6088

6090 if not defined (Bug#8403).
6091
6092 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
6093
6094 * xdisp.c (display_count_lines): Remove parameter `start',
6095 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

6147 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
6148 (FletX, Flet): Obey lexical binding.
6149 (Fcommandp): Handle closures.
6150 (Feval): New `lexical' arg.
6151 (eval_sub): New function extracted from Feval. Use it almost
6152 everywhere where Feval was used. Look up vars in lexical env.
6153 Handle closures.
6154 (Ffunctionp): Move from subr.el.
6155 (Ffuncall): Handle closures.
6156 (apply_lambda): Remove `eval_flags'.
6157 (funcall_lambda): Handle closures and new byte-code-functions.
6158 (Fspecial_variable_p): New function.
6159 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
6160 but without exporting it to Lisp.
6161

6163 * data.c (Finteractive_form): Handle closures.
6164
6165 * callint.c (Fcall_interactively): Preserve lexical-binding mode for

6186 (redisplay_window): Even when falling back on "recentering",
6187 position point in the window according to scroll-conservatively,
6188 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
6189
6190 (try_scrolling): When point is above the window, allow searching
6191 as far as scroll_max, or one screenful, to compute vertical
6192 distance from PT to the scroll margin position. This prevents
6193 try_scrolling from unnecessarily failing when
6194 scroll-conservatively is set to a value slightly larger than the
6195 window height. Clean up the case of PT below the margin at bottom
6196 of window: scroll_max can no longer be INT_MAX. When aggressive
6197 scrolling is in use, don't let point enter the opposite scroll
6198 margin as result of the scroll.
6199 (syms_of_xdisp) <scroll-conservatively>: Document the
6200 threshold of 100 lines for never-recentering scrolling.
6201

6217
6218 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
6219 steal a few bits to be more compact.

6221 Remove unneeded casts.
6222

6252 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
6253 instead of alloca (Bug#8344).
6254
6255 * eval.c (Fbacktrace): Don't assume nargs fits in int.
6256 (Fbacktrace_frame): Don't assume nframes fits in int.
6257
6258 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
6259
6260 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
6261 concerns.
6262
6263 * term.c (produce_glyphless_glyph): Remove unnecessary test.
6264
6265 * cm.c (calccost): Turn while-do into do-while, for clarity.
6266
6267 * keyboard.c (syms_of_keyboard): Use the same style as later
6268 in this function when indexing through an array. This also
6269 works around GCC bug 48267.
6270
6271 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
6272
6273 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
6274
6275 * chartab.c (sub_char_table_ref_and_range): Redo for slight
6276 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
6277
6278 * keyboard.c, keyboard.h (num_input_events): Now size_t.
6279 This avoids undefined behavior on integer overflow, and is a bit
6280 more convenient anyway since it is compared to a size_t variable.
6281
6282 Variadic C functions now count arguments with size_t, not int.
6283 This avoids an unnecessary limitation on 64-bit machines, which
6284 caused (substring ...) to crash on large vectors (Bug#8344).
6285 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
6286 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

6293 (funcall_lambda, mark_backtrace): Likewise.
6294 * fns.c (concat): Likewise.
6295 * frame.c (x_set_frame_parameters): Likewise.
6296 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
6297 0 if not found, not -1. All callers changed.
6298
6299 * alloc.c (garbage_collect): Don't assume stack size fits in int.
6300 (stack_copy_size): Now size_t, not int.
6301 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

6308
6309 * lisp.h (multibyte_char_to_unibyte):
6310 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
6311 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

6320
6321 * keyboard.c (safe_run_hook_funcall): New function.
6322 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
6323 don't set the hook to nil, but remove the offending function instead.
6324 (Qcommand_hook_internal): Remove, unused.
6325 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
6326 Vcommand_hook_internal.
6327
6328 * eval.c (enum run_hooks_condition): Remove.
6329 (funcall_nil, funcall_not): New functions.
6330 (run_hook_with_args): Call each function through a `funcall' argument.

6333 (Frun_hook_with_args_until_failure): Adjust accordingly.
6334 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
6335
6336 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
6337
6338 * dispextern.h (string_buffer_position): Remove declaration.
6339
6340 * print.c (strout): Remove parameter `multibyte', unused since
6341 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
6342
6343 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
6344 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
6345 All callers changed.
6346
6347 * w32.c (_wsa_errlist): Use braces for struct initializers.
6348
6349 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
6350 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.

6388 2011-03-26 Eli Zaretskii <eliz@gnu.org>
6389
6390 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
6391 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
6392
6393 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
6394
6395 * w32.c (read_unc_volume): Use parameter `henum', instead of
6396 global variable `wget_enum_handle'.
6397
6398 * keymap.c (describe_vector): Remove parameters `indices' and
6399 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

6510 unconditionnaly since it does the check itself.
6511
6512 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
6513
6514 Fix more problems found by GCC 4.5.2's static checks.
6515
6516 * coding.c (encode_coding_raw_text): Avoid unnecessary test
6517 the first time through the loop, since we know p0 < p1 then.
6518 This also avoids a gcc -Wstrict-overflow warning.
6519
6520 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
6521 leading to a memory leak, possible in functions like
6522 load_charset_map_from_file that can allocate an unbounded number
6523 of objects (Bug#8318).
6524
6525 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
6526 that could (at least in theory) be that large.
6527
6528 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
6529 This is less likely to overflow, and avoids undefined behavior if
6530 overflow does occur. All callers changed. Use strtoul to scan
6531 for the unsigned long integer.
6532 (pint2hrstr): Simplify and tune code slightly.
6533 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
6534

6536 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
6537
6538 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
6539 This also avoids a warning with gcc -Wstrict-overflow.

6542
6543 * fileio.c (Fcopy_file): Report error if fchown or fchmod
6544 fail (Bug#8306).
6545
6546 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
6547
6548 * process.c (Fmake_network_process): Use socklen_t, not int,
6549 where POSIX says socklen_t is required in portable programs.
6550 This fixes a porting bug on hosts like 64-bit HP-UX, where
6551 socklen_t is wider than int (Bug#8277).
6552 (Fmake_network_process, server_accept_connection):
6553 (wait_reading_process_output, read_process_output):
6554 Likewise.
6555
6556 * process.c: Rename or move locals to avoid shadowing.

6563 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
6564 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
6565
6566 Make tparam.h and terminfo.c consistent.
6567 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
6568 Include tparam.h instead, since it declares them.
6569 * cm.h (PC): Remove extern decl; tparam.h now does this.
6570 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
6571 * terminfo.c: Include tparam.h, to check interfaces.
6572 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
6573 (tparam): Adjust signature to match interface in tparam.h;
6574 this removes some undefined behavior. Check that outstring and len
6575 are zero, which they always are with Emacs.
6576 * tparam.h (PC, BC, UP): New extern decls.
6577
6578 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
6579 (xftfont_open): Rename locals to avoid shadowing.

6586 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
6587 Rename locals to avoid shadowing.
6588
6589 * xfont.c (xfont_list_family): Mark var as initialized.
6590
6591 * xml.c (make_dom): Now static.
6592
6593 * composite.c (composition_compute_stop_pos): Rename local to
6594 avoid shadowing.
6595 (composition_reseat_it): Remove unused locals.
6596 (find_automatic_composition, composition_adjust_point): Likewise.
6597 (composition_update_it): Mark var as initialized.
6598 (find_automatic_composition): Mark vars as initialized,
6599 with a FIXME (Bug#8290).
6600
6601 character.h: Rename locals to avoid shadowing.
6602 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
6603 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
6604 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
6605 (BUF_DEC_POS): Be more systematic about renaming local temporaries
6606 to avoid shadowing.
6607
6608 * textprop.c (property_change_between_p): Remove; unused.
6609
6610 * intervals.c (interval_start_pos): Now static.
6611

6615 Rename locals to avoid shadowing.
6616
6617 * sound.c (wav_play, au_play, Fplay_sound_internal):
6618 Fix pointer signedness.
6619 (alsa_choose_format): Remove unused local var.
6620 (wav_play): Initialize a variable to 0, to prevent undefined
6621 behavior (Bug#8278).
6622
6623 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
6624
6625 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
6626
6627 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
6628 clobbering (Bug#8298).
6629 * sysdep.c (sys_subshell): Likewise.
6630 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
6631
6632 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
6633 This should get cleaned up, so that child_setup has the
6634 same signature on all platforms.
6635
6636 * callproc.c (call_process_cleanup): Now static.
6637 (relocate_fd): Rename locals to avoid shadowing.
6638
6639 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
6640
6641 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
6642 not to be necessary, and produces flickering.
6643
6644 2011-03-20 Glenn Morris <rgm@gnu.org>
6645
6646 * config.in: Remove file.
6647

6657 (completing-read-default): Rename from completing-read.
6658 (completing-read): Call completing-read-function.
6659
6660 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
6661

6761
6762 * lisp.h (get_system_name, get_operating_system_release):
6763 Move decls here, to check interfaces.
6764 * process.c (get_operating_system_release): Move decl to lisp.h.
6765 * xrdb.c (get_system_name): Likewise.
6766 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
6767 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
6768 some of which prompt warnings from gcc -Wbad-function-cast.

6778 ENABLE_CHECKING is not defined.
6779

6798 (Fmemory_limit): Cast sbrk's returned value to char *.

6805 Use functions, not macros, for up- and down-casing (Bug#8254).
6806 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6807 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
6808 to use the following functions instead of these macros.
6809 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
6810 EMACS_INT, since callers assume the returned value fits in int.
6811 (upcase1): Likewise, for UPCASE_TABLE.
6812 (uppercasep, lowercasep, upcase): New static inline functions.
6813 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

6819 (regex_compile, re_search_2, re_match_2_internal):
6820 Remove unused local vars.
6821 (FREE_VAR): Rewrite so as not to use empty "else",
6822 which gcc can warn about.
6823 (regex_compile, re_match_2_internal): Mark locals as initialized.
6824 (RETALLOC_IF): Define only if needed.
6825 (WORDCHAR_P): Likewise. This one is never needed, but is used
6826 only in a comment talking about a compiler bug, so put inside
6827 the #if 0 of that comment.
6828 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
6829 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
6830 Remove; unused.
6831
6832 * search.c (boyer_moore): Rename locals to avoid shadowing.

6841
6842 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
6843
6844 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
6845 All uses changed.
6846 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
6847 Rename locals to avoid shadowing.
6848 (Fvertical_motion): Mark locals as initialized.
6849
6850 * casefiddle.c (casify_object, casify_region): Now static.
6851 (casify_region): Mark local as initialized.
6852
6853 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
6854
6855 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
6856 New macros, so that the caller can use some names other than
6857 gcpro1, gcpro2, etc.
6858 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
6859 of the new macros.
6860 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
6861 argument, for consistency with GCPRO2_VAR, etc: it is now the
6862 prefix of the variable, not the variable itself. All uses
6863 changed.
6864 * dired.c (directory_files_internal, file_name_completion):
6865 Rename locals to avoid shadowing.
6866
6867 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
6868 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
6869 dired.c's scmp function, had undefined behavior.
6870 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
6871 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
6872 * buffer.h: ... to here, because these macros use current_buffer,
6873 and the new implementation with inline functions needs to have
6874 current_buffer in scope now, rather than later when the macros
6875 are used.
6876 (downcase, upcase1): New static inline functions.
6877 (DOWNCASE, UPCASE1): Reimplement using these functions.
6878 This avoids undefined behavior in expressions like
6879 DOWNCASE (x) == DOWNCASE (y), which previously suffered
6880 from race conditions in accessing the global variables
6881 case_temp1 and case_temp2.
6882 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
6883 * lisp.h (case_temp1, case_temp2): Remove their decls.
6884 * character.h (ASCII_CHAR_P): Move from here ...
6885 * lisp.h: ... to here, so that the inline functions mentioned
6886 above can use them.
6887
6888 * dired.c (directory_files_internal_unwind): Now static.
6889
6890 * fileio.c (file_name_as_directory, directory_file_name):
6891 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
6892 Now static.
6893 (file_name_as_directory): Use const pointers when appropriate.
6894 (Fexpand_file_name): Likewise. In particular, newdir might
6895 point at constant storage, so make it a const pointer.
6896 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
6897 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
6898 signedness issues.
6899 (Fset_file_times, Finsert_file_contents, auto_save_error):
6900 Rename locals to avoid shadowing.
6901
6902 * minibuf.c (choose_minibuf_frame_1): Now static.
6903 (Ftry_completion, Fall_completions): Rename or remove locals
6904 to avoid shadowing.
6905
6906 * marker.c (bytepos_to_charpos): Remove; unused.
6907
6908 * lisp.h (verify_bytepos, count_markers): New decls,
6909 so that gcc does not warn that these functions aren't declared.
6910
6911 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
6912 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
6913 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
6914 (copy_text): Remove unused local var.
6915
6916 * filelock.c (within_one_second): Now static.
6917 (lock_file_1): Rename local to avoid shadowing.
6918
6919 * buffer.c (fix_overlays_before): Mark locals as initialized.
6920 (fix_start_end_in_overlays): Likewise. This function should be
6921 simplified by using pointers-to-pointers, but that's a different
6922 matter.
6923 (switch_to_buffer_1): Now static.
6924 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
6925 (report_overlay_modification): Rename locals to avoid shadowing.
6926
6927 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
6928 Fix pointer signedness issue.
6929 (sys_subshell): Mark local as volatile if checking for lint,
6930 to suppress a gcc -Wclobbered warning that does not seem to be right.
6931 (MAXPATHLEN): Define only if needed.
6932
6933 * process.c (serial_open, serial_configure): Move decls from here ...
6934 * systty.h: ... to here, so that they can be checked.
6935
6936 * fns.c (get_random, seed_random): Move extern decls from here ...
6937 * lisp.h: ... to here, so that they can be checked.
6938
6939 * sysdep.c (reset_io): Now static.
6940 (wait_for_termination_signal): Remove; unused.
6941
6942 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
6943 (copy_keymap_item, append_key, push_text_char_description):
6944 Now static.
6945 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
6946 (DENSE_TABLE_SIZE): Remove; unused.
6947 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
6948 (describe_map_tree):
6949 Rename locals to avoid shadowing.
6950
6951 * keyboard.c: Declare functions static if they are not used elsewhere.
6952 (echo_char, echo_dash, cmd_error, top_level_2):
6953 (poll_for_input, handle_async_input): Now static.
6954 (read_char, kbd_buffer_get_event, make_lispy_position):
6955 (make_lispy_event, make_lispy_movement, apply_modifiers):
6956 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
6957 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
6958 (Fread_key_sequence_vector): Rename locals to avoid shadowing.

6961
6962 * keyboard.h (make_ctrl_char): New decl.
6963 (mark_kboards): Move decl here ...
6964 * alloc.c (mark_kboards): ... from here.
6965
6966 * lisp.h (force_auto_save_soon): New decl.
6967
6968 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
6969 (DEFINE_DUMMY_FUNCTION): New macro.
6970 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
6971 Use it.
6972 (main): Add casts to avoid warnings
6973 if GCC considers string literals to be constants.
6974
6975 * lisp.h (fatal_error_signal): Add decl, since it's exported.
6976
6977 * dbusbind.c: Pointer signedness fixes.
6978 (xd_signature, xd_append_arg, xd_initialize):
6979 (Fdbus_call_method, Fdbus_call_method_asynchronously):
6980 (Fdbus_method_return_internal, Fdbus_method_error_internal):
6981 (Fdbus_send_signal, xd_read_message_1, Fdbus_register_service):
6982 (Fdbus_register_signal): Use SSDATA when the context wants char *.
6983

7021 * w32inevt.c (reinvoke_input_signal, lispy_function_keys):
7022 * w32menu.c (Qmenu_bar, QCtoggle, QCradio, Qoverriding_local_map)

7039 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
7040 Assign struct members directly, instead of using BUF_BEGV etc.

7117
7118 * editfns.c (time_overflow): New function, refactoring common code.
