20 * buffer.c: Memory overflow fixes.
21 (overlays_at, overlays_in, record_overlay_string, overlay_strings):
22 Don't update size of array until after memory allocation succeeds,

42
43 Use ptrdiff_t for hash table indexes.
44 * category.c (hash_get_category_set):
45 * ccl.c (ccl_driver):
46 * charset.h (struct charset.hash_index, CHECK_CHARSET_GET_ID):
47 * coding.c (coding_system_charset_list, detect_coding_system):
48 * coding.h (struct coding_system.id):
49 * composite.c (get_composition_id, gstring_lookup_cache):

51 * image.c (xpm_get_color_table_h):
52 * lisp.h (hash_lookup, hash_put):
53 * minibuf.c (Ftest_completion):
54 Use ptrdiff_t for hash table indexes, not int (which is too
55 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
56 32-bit --with-wide-int hosts).
57
58 * charset.c (Fdefine_charset_internal): Check for integer overflow.
59 Add a FIXME comment about memory leaks.
60 (syms_of_charset): Don't assume xmalloc returns.
61
62 Don't assume that stated character widths fit in int.
63 * character.c (Fchar_width, c_string_width, lisp_string_width):
64 * character.h (CHAR_WIDTH):
65 * indent.c (MULTIBYTE_BYTES_WIDTH):
66 Use sanitize_char_width to avoid undefined and/or bad behavior
67 with outlandish widths.
68 * character.h (sanitize_tab_width): Renamed from sanitize_width,
69 now that we have two such functions. All uses changed.
70 (sanitize_char_width): New inline function.
71
72 Don't assume that tab-width fits in int.
73 * character.h (sanitize_width): New inline function.
74 (SANE_TAB_WIDTH): New macro.
75 (ASCII_CHAR_WIDTH): Use it.
76 * indent.c (sane_tab_width): Remove. All uses replaced by
77 SANE_TAB_WIDTH (current_buffer).
78 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
79
80 * fileio.c: Integer overflow issues with file modes.
81 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
82
83 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
84 Remove unreachable code.
85 (read_hex, load_charset_map_from_file): Check for integer overflow.
86
87 * xterm.c: don't go over XClientMessageEvent limit
88 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
89 (x_send_scroll_bar_event): Likewise. Check that the size does not
90 exceed limits imposed by XClientMessageEvent, as well as the usual
91 ptrdiff_t and size_t limits.
92
93 * keyboard.c: Overflow, signedness and related fixes.
94 (make_lispy_movement): Use same integer type in forward decl
95 that is used in the definition.
96 (read_key_sequence, keyremap_step):
97 Change bufsize argument back to int, undoing my 2011-03-30 change.
98 We prefer signed types, and int is wide enough here.
99 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
100 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
101 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
102 length, not size_t. Use ptrdiff_t for index, not int.
103 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
104 possibility of integer overflow.
105
106 Overflow, signedness and related fixes for images.
107
108 * dispextern.h (struct it.stack[0].u.image.image_id)
109 (struct_it.image_id, struct image.id, struct image_cache.size)
110 (struct image_cache.used, struct image_cache.ref_count):
111 * gtkutil.c (update_frame_tool_bar):
112 * image.c (x_reference_bitmap, Fimage_size, Fimage_mask_p)
113 (Fimage_metadata, free_image_cache, clear_image_cache, lookup_image)
114 (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
115 * nsmenu.m (update_frame_tool_bar):
116 * xdisp.c (calc_pixel_width_or_height):
117 * xfns.c (image_cache_refcount):
118 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
119 on typical 64-bit hosts.
120
121 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
122 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
123 Omit unnecessary casts to int.
124 (parse_image_spec): Check that integers fall into 'int' range
125 when the callers expect that.
126 (image_ascent): Redo ascent calculation to avoid int overflow.
127 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
128 (lookup_image): Remove unnecessary tests.
129 (xbm_image_p): Locals are now of int, not EMACS_INT,
130 since parse_image_check makes sure they fit into int.
131 (png_load, gif_load, svg_load_image):
132 Prefer int to unsigned where either will do.
133 (tiff_handler): New function, combining the cores of the
134 old tiff_error_handler and tiff_warning_handler. This
135 function is rewritten to use vsnprintf and thereby avoid
136 stack buffer overflows. It uses only the features of vsnprintf
137 that are common to both POSIX and native Microsoft.
138 (tiff_error_handler, tiff_warning_handler): Use it.
139 (tiff_load, gif_load, imagemagick_load_image):
140 Don't assume :index value fits in 'int'.
141 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
142 (imagemagick_load_image): Check that crop parameters fit into
143 the integer types that MagickCropImage accepts. Don't assume
144 Vimagemagick_render_type has a nonnegative value. Don't assume
145 size_t fits in 'long'.
146 (gs_load): Use printmax_t to print the widest integers possible.
147 Check for integer overflow when computing image height and width.
148
149 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
150
151 Integer signedness and overflow and related fixes. (Bug#9079)
152
153 * bidi.c: Integer size and overflow fixes.
154 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
155 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
156 (bidi_cache_find_level_change, bidi_cache_ensure_space)
157 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
158 (bidi_find_other_level_edge):
159 Use ptrdiff_t instead of EMACS_INT where either will do.
160 This works better on 32-bit hosts configured --with-wide-int.
161 (bidi_cache_ensure_space): Check for size-calculation overflow.
162 Use % rather than repeated addition, for better worst-case speed.
163 Don't set bidi_cache_size until after xrealloc returns, because it
164 might not return.
165 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
166 (bidi_cache_ensure_space): Also check that the bidi cache size
167 does not exceed that of the largest Lisp string or buffer. See Eli
168 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
169
170 * alloc.c (__malloc_size_t): Remove.
171 All uses replaced by size_t. See Andreas Schwab's note
172 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
173
174 * image.c: Improve checking for integer overflow.
175 (check_image_size): Assume that f is nonnull, since
176 it is always nonnull in practice. This is one less thing to
177 worry about when checking for integer overflow later.
178 (x_check_image_size): New function, which checks for integer
179 overflow issues inside X.
180 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
181 This removes the need for a memory_full check.
182 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
183 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
184 (xbm_read_bitmap_data): Change locals back to 'int', since
185 their values must fit in 'int'.
186 (xpm_load_image, png_load, tiff_load):
187 Invoke x_create_x_image_and_pixmap earlier,
188 to avoid much needless work if the image is too large.
189 (tiff_load): Treat overly large images as if
190 x_create_x_image_and_pixmap failed, not as malloc failures.
191 (gs_load): Use x_check_image_size.
192
193 * gtkutil.c: Omit integer casts.
194 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
195 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
196
197 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
198
199 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
200 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
201 would wrongly return t on a 64-bit host.
202
203 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
204 The plain *_OVERFLOW macros run afoul of GCC bug 49705
205 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
206 and therefore cause GCC to emit a bogus diagnostic in some cases.
207
208 * image.c: Integer signedness and overflow and related fixes.
209 This is not an exhaustive set of fixes, but it's time to
210 record what I've got.
211 (lookup_pixel_color, check_image_size): Remove redundant decls.
212 (check_image_size): Don't assume that arbitrary EMACS_INT values
213 fit in 'int', or that arbitrary 'double' values fit in 'int'.
214 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
215 (tiff_load, imagemagick_load_image):
216 Check for overflow in size calculations.
217 (x_create_x_image_and_pixmap): Remove unnecessary test for
218 xmalloc returning NULL; that can't happen.
219 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
220 (xpm_color_bucket): Use better integer hashing function.
221 (xpm_cache_color): Don't possibly over-allocate memory.
222 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
223 (gif_memory_source):
224 Use ptrdiff_t, not int or size_t, to record sizes.
225 (png_load): Don't assume values greater than 2**31 fit in 'int'.
226 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
227 either works, as we prefer signed integers.
228 (tiff_read_from_memory, tiff_write_from_memory):
229 Return tsize_t, not size_t, since that's what the TIFF API wants.
230 (tiff_read_from_memory): Don't fail simply because the read would
231 go past EOF; instead, return a short read.
232 (tiff_load): Omit no-longer-needed casts.
233 (Fimagemagick_types): Don't assume size fits into 'int'.
234
235 Improve hashing quality when configured --with-wide-int.
236 * fns.c (hash_string): New function, taken from sxhash_string.
237 Do not discard information about ASCII character case; this
238 discarding is no longer needed.
239 (sxhash-string): Use it. Change sig to match it. Caller changed.
240 * lisp.h: Declare it.
241 * lread.c (hash_string): Remove, since we now use fns.c's version.
242 The fns.c version returns a wider integer if --with-wide-int is
243 specified, so this should help the quality of the hashing a bit.
244
245 * emacs.c: Integer overflow minor fix.
246 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
247 Define only if GNU_LINUX.
248 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
249
250 * dispnew.c: Integer signedness and overflow fixes.
251 Remove unnecessary forward decls, that were a maintenance hassle.
252 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
253 All uses changed.
254 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
255 (scrolling_window): Use ptrdiff_t, not int, for byte count.
256 (prepare_desired_row, line_draw_cost):
257 Use int, not unsigned, where either works.
258 (save_current_matrix, restore_current_matrix):
259 Use ptrdiff_t, not size_t, where either works.
260 (init_display): Check for overflow more accurately, and without
261 relying on undefined behavior.
262
263 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
264 Remove, replacing with the new symbols in lisp.h. All uses changed.
265 * fileio.c (make_temp_name):
266 * filelock.c (lock_file_1, lock_file):
267 * xdisp.c (message_dolog):
268 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
269 Use pMd etc. instead.
270 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
271 replacing the pWIDE etc. symbols removed from editfns.c.
272
273 * keyboard.h (num_input_events): Now uintmax_t.
274 This is (very slightly) less likely to mess up due to wraparound.
275 All uses changed.
276
277 * buffer.c: Integer signedness fixes.
278 (alloc_buffer_text, enlarge_buffer_text):
279 Use ptrdiff_t rather than size_t when either will do, as we prefer
280 signed integers.
281
282 * alloc.c: Integer signedness and overflow fixes.
283 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
284 (__malloc_size_t): Default to size_t, not to int.
285 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
286 (Fgarbage_collect, mark_object_loop_halt, mark_object):
287 Prefer ptrdiff_t to size_t when either would do, as we prefer
288 signed integers.
289 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
290 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
291 Now const. Initialize with values that are in range even if char
292 is signed.
293 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
294 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
295 These functions do the right thing with sizes > 2**32.
296 (check_depth): Now ptrdiff_t, not int.
297 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
298 Adjust to new way of storing sizes. Check for size overflow bugs
299 in rest of code.
300 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
301 slightly wrong anyway, as it missed one instance of
302 XMALLOC_OVERRUN_CHECK_OVERHEAD.
303 (refill_memory_reserve): Omit needless cast to size_t.
304 (mark_object_loop_halt): Mark as externally visible.
305
306 * xselect.c: Integer signedness and overflow fixes.
307 (Fx_register_dnd_atom, x_handle_dnd_message):
308 Use ptrdiff_t, not size_t, since we prefer signed.
309 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
310 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
311 x_dnd_atoms_size and x_dnd_atoms_length.
312
313 * doprnt.c: Prefer signed to unsigned when either works.
314 * eval.c (verror):
315 * doprnt.c (doprnt):
316 * lisp.h (doprnt):
317 * xdisp.c (vmessage):
318 Use ptrdiff_t, not size_t, when using or implementing doprnt,
319 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
320 prefer signed arithmetic to avoid comparison confusion.
321 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
322 but is a bit tricky.
323
324 Assume freestanding C89 headers, string.h, stdlib.h.
325 * data.c, doprnt.c, floatfns.c, print.c:
326 Include float.h unconditionally.
327 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
328 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
329 * regex.c: Likewise for stddef.h, string.h.
330 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
331 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
332 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
333 (STDC_HEADERS): Remove obsolete defines.
334 * sysdep.c: Include limits.h unconditionally.
335
336 Assume support for memcmp, memcpy, memmove, memset.
337 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
338 * regex.c (memcmp, memcpy):
339 Remove; we assume C89 now.
340
341 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
342 (__malloc_safe_bcopy): Remove; no longer needed.
343
344 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
345 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
346 well either way, and we prefer signed to unsigned.
347
348 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
349
350 Port to OpenBSD.
351 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
352 and the surrounding thread.
353 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
354 rather than fgets, and retry after EINTR. Otherwise, 'emacs
355 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
356 timer goes off.
357 * s/openbsd.h (BROKEN_SIGIO): Define.
358 * unexelf.c (unexec) [__OpenBSD__]:
359 Don't update the .mdebug section of the Alpha COFF symbol table.
360
361 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
362
363 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
364 (bug#8460).
365
366 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
367
368 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
369 This fixes some race conditions on the permissions of any newly
370 created file.
371
372 * alloc.c (valid_pointer_p): Use pipe, not open.
373 This fixes some permissions issues when debugging.
374
375 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
376 If fchown fails to set both uid and gid, try to set just gid,
377 as that is sometimes allowed. Adjust the file's mode to eliminate
378 setuid or setgid bits that are inappropriate if fchown fails.
379
380 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
381
382 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
383 to compare Lisp_Objects.
384 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
385 global_gnutls_log_level, don't mistake it for a Lisp_Object.
386 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
387
388 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
389
390 * lread.c (read_integer): Unread even EOF character.
391 (read1): Likewise. Properly record start position of symbol.
392
393 * lread.c (read1): Read `#:' as empty uninterned symbol if no
394 symbol character follows.
395
396 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
397
398 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
399 This works around a problem with the previous change to Fcopy_file.
400 Recent glibc declares fchown with __attribute__((warn_unused_result)),
401 and without this change, GCC might complain about discarding
402 fchown's return value.
403
404 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
405
406 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
407
408 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
409
410 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
411
412 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
413
414 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
415 it's used from the C level.
416
417 * process.c: Use the same condition for POLL_FOR_INPUT in both
418 keyboard.c and process.c (bug#1858).
419
420 2011-07-09 Lawrence Mitchell <wence@gmx.li>
421
422 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
423 (Fgnutls_boot): Use it.
424
425 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
426
427 * doc.c (Fsubstitute_command_keys): Revert last change.
428
429 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
430
431 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
432 quotes the next character, and doesn't affect other longer
433 sequences (bug#8935).
434
435 * lread.c (syms_of_lread): Clarify that is isn't only
436 `eval-buffer' and `eval-defun' that's affected by

445 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
446
447 Fix minor problems found by static checking.
448 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
449 (elsz): Now a signed constant, not a size_t var. We prefer signed
450 types to unsigned, to avoid integer comparison confusion. Without
451 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
452 "cannot optimize loop, the loop counter may overflow", a symptom
453 of the confusion.
454 * indent.c (Fvertical_motion): Mark locals as initialized.

480 buffer position was specified. Initialize paragraph_embedding to
481 L2R.
482 (reseat_to_string): Initialize the bidi iterator.
483 (display_string): If we need to ignore text properties of
484 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
485 original value of -1 will not work with bidi.)
486 (compute_display_string_pos): First arg is now struct
487 `text_pos *'; all callers changed. Support display properties on
488 Lisp strings.
489 (compute_display_string_end): Support display properties on Lisp
490 strings.
491 (init_iterator, reseat_1, reseat_to_string): Initialize the

495 calculation of the object to scan. Fixes an error when using
496 arrow keys.
497 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
498 base_level_stop; instead, set base_level_stop to BEGV. Fixes
499 crashes in vertical-motion.
500 (next_element_from_buffer): Improve commentary for when
501 the iterator is before prev_stop.
502 (init_iterator): Initialize bidi_p from the default value of
503 bidi-display-reordering, not from buffer-local value. Use the
504 buffer-local value only if initializing for buffer iteration.

506 that are being bidi-reordered.
507 (set_iterator_to_next): Support bidi reordering of C strings and

523 character that is not the first one in the visual order.
524 (get_visually_first_element): New function, refactored from common
525 parts of next_element_from_buffer, next_element_from_string, and
526 next_element_from_c_string.
527 (tool_bar_lines_needed, redisplay_tool_bar)
528 (display_menu_bar): Force left-to-right direction. Add a FIXME
529 comment for making that be controlled by a user option.
530 (push_it, pop_it): Save and restore the state of the
531 bidi iterator. Save and restore the bidi_p flag.
532 (pop_it): Iterate out of display property for string iteration as
533 well.
534 (iterate_out_of_display_property): Support iteration over strings.

543 pushed the iterator stack, restore the internal state of the bidi
544 iterator by calling bidi_pop_it same number of times.
545 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
546 and we are bidi-iterating, don't decrement the iterator position;
547 instead, set the first_elt flag in the bidi iterator, to produce
548 the same effect.
549 (reseat_1): Remove redundant setting of string_from_display_prop_p.
550 (push_display_prop): xassert that we are iterating a buffer.
551 (push_it, pop_it): Save and restore paragraph_embedding member.
552 (handle_single_display_spec, next_overlay_string)
553 (get_overlay_strings_1, reseat_1, reseat_to_string)
554 (push_display_prop): Set up the `unibyte' member of bidi_it.string
555 correctly. Don't assume unibyte strings are not bidi-reordered.

561 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
562 (pop_it): Call iterate_out_of_display_property only if we are
563 popping after iteration over a string that came from a display
564 property. Fix a typo in popping stretch info. Add an assertion
565 for verifying that the iterator position is in sync with the bidi
566 iterator.
567 (handle_single_display_spec, get_overlay_strings_1)
568 (push_display_prop): Fix initialization of paragraph direction for
569 string when that of the parent object is not yet determined.
570 (reseat_1): Call bidi_init_it to resync the bidi
571 iterator with IT's position. (Bug#7616)
572 (find_row_edges): If ROW->start.pos gives position
573 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
574 (handle_stop, back_to_previous_visible_line_start, reseat_1):
575 Reset the from_disp_prop_p flag.
576 (SAVE_IT, RESTORE_IT): New macros.

582 saving a temporary copy of the iterator and restoring it back.
583 (back_to_previous_visible_line_start, reseat_1)
584 (init_iterator): Empty the bidi cache "stack".
585 (move_it_in_display_line_to): If iterator ended up at
586 EOL, but we never saw any buffer positions smaller than
587 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
588 motion in bidi-reordered lines.
589 (move_it_in_display_line_to): Record prev_method and prev_pos
590 immediately before the call to set_iterator_to_next. Fixes cursor
591 motion in bidi-reordered lines with stretch glyphs and strings
592 displayed in margins. (Bug#8133) (Bug#8867)
593 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
594 TO_CHARPOS.
595 (pos_visible_p): Support positions in bidi-reordered lines. Save
596 and restore bidi cache.
597
598 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.

1016
1017 Random fixes. E.g., (random) never returned negative values.
1018 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
1019 subseconds part to the entropy, as that's a bit more random.
1020 Prefer signed to unsigned, since the signedness doesn't matter and
1021 in general we prefer signed. When given a limit, use a
1022 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
1023 latter isn't right if USE_2_TAGS_FOR_INTS.
1024 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
1025 not 0..VALMASK. Don't discard "excess" bits that random () returns.

1036
1037 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
1038 This is more efficient than Ffile_directory_p and avoids a minor race.
1039
1040 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
1041
1042 * buffer.c (Foverlay_put): Say what the return value is

1063 (syms_of_gnutls): Remove duplicate DEFSYM for
1064 Qgnutls_bootprop_verify_hostname_error, an error for
1065 Qgnutls_bootprop_verify_error (which is no longer used).
1066
1067 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
1068 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
1069 Also (re)move comments that are misplaced or no longer relevant.

1170 * eval.c (struct backtrace): Simplify and port the data structure.
1171 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
1172 signed bit field, as this assumption is not portable and it makes
1173 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
1174 "char debug_on_exit : 1" as this is not portable either; instead,
1175 use the portable "unsigned int debug_on_exit : 1". Remove unused
1176 member evalargs. Remove obsolete comments about cc bombing out.
1177

1343
1344 * print.c (printchar, strout): Check for string overflow.
1345 (PRINTPREPARE, printchar, strout):
1346 Don't set size unless allocation succeeds.
1347
1348 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
1349 for sizes. Check for string overflow more accurately.
1350 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
1351
1352 * macros.c: Integer and buffer overflow fixes.
1353 * keyboard.h (struct keyboard.kbd_macro_bufsize):
1354 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

1358 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
1359
1360 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
1361
1362 * lread.c: Integer overflow fixes.
1363 (read_integer): Radix is now EMACS_INT, not int,
1364 to improve quality of diagnostics for out-of-range radices.
1365 Calculate buffer size correctly for out-of-range radices.
1366 (read1): Check for integer overflow in radices, and in
1367 read-circle numbers.
1368 (read_escape): Avoid int overflow.
1369 (Fload, openp, read_buffer_size, read1)
1370 (substitute_object_recurse, read_vector, read_list, map_obarray):
1371 Use ptrdiff_t, not int, for sizes.

1390
1391 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
1392
1393 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
1394 The following patches are for when GLYPH_DEBUG && !XASSERT.
1395 * dispextern.h (trace_redisplay_p, dump_glyph_string):
1396 * dispnew.c (flush_stdout):
1397 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
1398 Mark as externally visible.
1399 * dispnew.c (check_window_matrix_pointers): Now static.
1400 * dispnew.c (window_to_frame_vpos):
1401 * xfns.c (unwind_create_frame):
1402 * xterm.c (x_check_font): Remove unused local.
1403 * scroll.c (CHECK_BOUNDS):
1404 * xfaces.c (cache_fache): Rename local to avoid shadowing.
1405 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
1406 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
1407 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
1408 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
1409 Now static.
1410 (debug_method_add): Use va_list and vsprintf rather than relying
1411 on undefined behavior with wrong number of arguments.
1412 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
1413 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
1414 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
1415 since we're not interested in debugging glyphs with old libraries.
1416 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
1417 GCC 4.6.0's static checking.
1418
1419 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
1420
1421 Integer overflow and signedness fixes (Bug#8873).

1436 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
1437 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
1438 (.bitmaps_last, struct x_output.icon_bitmap):
1439 Use ptrdiff_t, not int, for bitmap indexes.
1440 (x_allocate_bitmap_record): Check for size overflow.
1441 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
1442
1443 Use ptrdiff_t, not int, for overlay counts.
1444 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
1445 * editfns.c (overlays_around, get_pos_property):
1446 * textprop.c (get_char_property_and_overlay):
1447 * xdisp.c (next_overlay_change, note_mouse_highlight):
1448 * xfaces.c (face_at_buffer_position):
1449 * buffer.c (OVERLAY_COUNT_MAX): New macro.
1450 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
1451 (Fnext_overlay_change, Fprevious_overlay_change)
1452 (mouse_face_overlay_overlaps, Foverlays_in):
1453 Use ptrdiff_t, not int, for sizes.
1454 (overlays_at, overlays_in): Check for size-calculation overflow.
1455
1456 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
1457
1458 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
1459 (x_session_initialize): Do not assume string length fits in int.
1460
1461 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
1462 This is unlikely, but can occur if DPI is outlandish.
1463
1464 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
1465 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
1466
1467 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
1468 * xrdb.c (magic_file_p, search_magic_path):
1469 Omit last arg SUFFIX; it was always 0. All callers changed.
1470 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
1471
1472 * xfont.c (xfont_match): Avoid need for strlen.
1473
1474 * xfns.c: Don't assume strlen fits in int.
1475 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
1476
1477 * xdisp.c (message_log_check_duplicate): Return intmax_t,
1478 not unsigned long, as we prefer signed integers. All callers changed.
1479 Detect integer overflow in repeat count.
1480 (message_dolog): Don't assume print length fits in 39 bytes.
1481 (display_mode_element): Don't assume strlen fits in int.
1482
1483 * termcap.c: Don't assume sizes fit in int and never overflow.
1484 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
1485 (gobble_line): Check for size-calculation overflow.
1486
1487 * minibuf.c (Fread_buffer):
1488 * lread.c (intern, intern_c_string):
1489 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
1490 Don't assume string length fits in int.
1491

1500 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
1501
1502 * filelock.c: Fix some buffer overrun and integer overflow issues.
1503 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
1504 Reformulate so as not to need the command string.
1505 Invoke gzip -cd rather than gunzip, as it's more portable.
1506 (lock_info_type, lock_file_1, lock_file):
1507 Don't assume pid_t and time_t fit in unsigned long.
1508 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
1509 (current_lock_owner): Prefer signed type for sizes.
1510 Use memcpy, not strncpy, where memcpy is what is really wanted.
1511 Don't assume (via atoi) that time_t and pid_t fit in int.
1512 Check for time_t and/or pid_t out of range, e.g., via a network share.
1513 Don't alloca where an auto var works fine.
1514
1515 * fileio.c: Fix some integer overflow issues.
1516 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
1517 Don't assume string length fits in int.
1518 (directory_file_name): Don't assume string length fits in long.
1519 (make_temp_name): Don't assume pid fits in int, or that its print
1520 length is less than 20.
1521
1522 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
1523
1524 * coding.c (make_subsidiaries): Don't assume string length fits in int.
1525
1526 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
1527
1528 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
1529 We prefer signed integers, even for size calculations.
1530
1531 * emacs.c: Don't assume string length fits in 'int'.
1532 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
1533 (main): Don't invoke strlen when not needed.
1534
1535 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
1536 (XD_DEBUG_MESSAGE): Don't waste a byte.
1537
1538 * callproc.c (getenv_internal_1, getenv_internal)
1539 (Fgetenv_internal):
1540 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
1541
1542 * lread.c (invalid_syntax): Omit length argument.
1543 All uses changed. This doesn't fix a bug, but it simplifies the
1544 code away from its former Hollerith-constant appearance, and it's
1545 one less 'int' to worry about when looking at integer-overflow issues.
1546 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
1547
1548 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
1549 This didn't break anything, but it didn't help either.
1550 It's confusing to put a bogus integer in a place where the actual
1551 value does not matter.
1552 (LIST_END_P): Remove unused macro and its bogus comment.
1553 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
1554
1555 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
1556 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
1557 implementation.
1558 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
1559 We prefer signed types, and the value cannot exceed the EMACS_INT
1560 range anyway (because otherwise the length would not be representable).
1561 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
1562 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
1563 This avoids a GCC warning when WIDE_EMACS_INT.
1564
1565 * indent.c (sane_tab_width): New function.
1566 (current_column, scan_for_column, Findent_to, position_indentation)
1567 (compute_motion): Use it. This is just for clarity.
1568 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
1569
1570 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
1571
1572 * lisp.h (lint_assume): New macro.
1573 * composite.c (composition_gstring_put_cache):
1574 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
1575
1576 * editfns.c, insdel.c:
1577 Omit unnecessary forward decls, to simplify future changes.
1578
1579 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
1580
1581 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
1582
1583 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
1584 Use much-faster test for byte-length change.
1585 Don't assume string byte-length fits in 'int'.
1586 Check that character arg fits in 'int'.
1587 (mapcar1): Declare byte as byte, for clarity.
1588
1589 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
1590
1591 * fns.c (concat): Catch string overflow earlier.
1592 Do not rely on integer wraparound.
1593
1594 * dispextern.h (struct it.overlay_strings_charpos)
1595 (struct it.selective): Now EMACS_INT, not int.
1596 * xdisp.c (forward_to_next_line_start)
1597 (back_to_previous_visible_line_start)
1598 (reseat_at_next_visible_line_start, next_element_from_buffer):
1599 Don't arbitrarily truncate the value of 'selective' to int.
1600
1601 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
1602
1603 * composite.c: Don't truncate sizes to 'int'.
1604 (composition_gstring_p, composition_reseat_it)
1605 (composition_adjust_point): Use EMACS_INT, not int.
1606 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
1607 not EMACS_UINT, for indexes.
1608
1609 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
1610
1611 * buffer.c: Include <verify.h>.
1612 (struct sortvec.priority, struct sortstr.priority):
1613 Now EMACS_INT, not int.
1614 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
1615 (struct sortstr.size, record_overlay_string)
1616 (struct sortstrlist.size, struct sortlist.used):
1617 Don't truncate size to int.
1618 (record_overlay_string): Check for size-calculation overflow.
1619 (init_buffer_once): Check at compile-time, not run-time.
1620
1621 2011-06-22 Jim Meyering <meyering@redhat.com>
1622
1623 Don't leak an XBM-image-sized buffer
1624 * image.c (xbm_load): Free the image buffer after using it.
1625
1626 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
1627
1628 Port to Sun C.
1629 * composite.c (find_automatic_composition): Omit needless 'return 0;'
1630 that Sun C diagnosed.
1631 * fns.c (secure_hash): Fix pointer signedness issue.
1632 * intervals.c (static_offset_intervals): New function.
1633 (offset_intervals): Use it.
1634
1635 2011-06-21 Leo Liu <sdl.web@gmail.com>
1636
1637 * deps.mk (fns.o):
1638 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
1639 sha512.h.
1640
1641 * fns.c (secure_hash): Rename from crypto_hash_function and change
1642 the first arg to accept symbols.
1643 (Fsecure_hash): New primitive.
1644 (syms_of_fns): New symbols.
1645
1646 2011-06-20 Deniz Dogan <deniz@dogan.se>
1647
1648 * process.c (Fset_process_buffer): Clarify return value in
1649 docstring.
1650
1651 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
1652
1653 * dispnew.c (add_window_display_history): Use BVAR.
1654
1655 * xdisp.c (debug_method_add): Use BVAR.
1656 (check_window_end, dump_glyph_matrix, dump_glyph)
1657 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
1658
1659 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
1660 Likewise.
1661
1662 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
1663 check till after the cache is created in init_frame_faces.
1664
1665 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
1666
1667 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
1668
1669 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
1670
1671 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
1672 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
1673 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
1674
1675 Improve buffer-overflow checking (Bug#8873).
1676 * fileio.c (Finsert_file_contents):
1677 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
1678 Remove the old (too-loose) buffer overflow checks.
1679 They weren't needed, since make_gap checks for buffer overflow.
1680 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
1681 The old code merely checked for Emacs fixnum overflow, and relied
1682 on undefined (wraparound) behavior. The new code avoids undefined
1683 behavior, and also checks for ptrdiff_t and/or size_t overflow.
1684
1685 * editfns.c (Finsert_char): Don't dump core with very negative counts.
1686 Tune. Don't use wider integers than needed. Don't use alloca.
1687 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
1688
1689 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
1690
1691 * insdel.c, lisp.h (buffer_overflow): New function.
1692 (insert_from_buffer_1, replace_range, replace_range_2):
1693 * insdel.c (make_gap_larger):
1694 * editfns.c (Finsert_char):
1695 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
1696
1697 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
1698
1699 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
1700
1701 Integer overflow and signedness fixes (Bug#8873).
1702
1703 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
1704 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
1705
1706 * fileio.c: Don't assume EMACS_INT fits in off_t.
1707 (emacs_lseek): New static function.
1708 (Finsert_file_contents, Fwrite_region): Use it.
1709 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
1710
1711 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
1712
1713 * fns.c: Don't overflow int when computing a list length.
1714 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
1715 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
1716 truncation on 64-bit hosts. Check for QUIT every
1717 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
1718 faster and is responsive enough.
1719 (Flength): Report an error instead of overflowing an integer.
1720 (Fsafe_length): Return a float if the value is not representable
1721 as a fixnum. This shouldn't happen except in contrived situations.
1722 (Fnthcdr, Fsort): Don't assume list length fits in int.
1723 (Fcopy_sequence): Don't assume vector length fits in int.
1724
1725 * alloc.c: Check that resized vectors' lengths fit in fixnums.
1726 (header_size, word_size): New constants.
1727 (allocate_vectorlike): Don't check size overflow here.
1728 (allocate_vector): Check it here instead, since this is the only
1729 caller of allocate_vectorlike that could cause overflow.
1730 Check that the new vector's length is representable as a fixnum.
1731
1732 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
1733 The previous code was bogus. For example, next_almost_prime (32)
1734 returned 39, which is undesirable as it is a multiple of 3; and
1735 next_almost_prime (24) returned 25, which is a multiple of 5 so
1736 why was the code bothering to check for multiples of 7?
1737
1738 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
1739
1740 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
1741
1742 Variadic C functions now count arguments with ptrdiff_t.
1743 This partly undoes my 2011-03-30 change, which replaced int with size_t.
1744 Back then I didn't know that the Emacs coding style prefers signed int.
1745 Also, in the meantime I found a few more instances where arguments
1746 were being counted with int, which may truncate counts on 64-bit
1747 machines, or EMACS_INT, which may be unnecessarily wide.
1748 * lisp.h (struct Lisp_Subr.function.aMANY)
1749 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
1750 Arg counts are now ptrdiff_t, not size_t.
1751 All variadic functions and their callers changed accordingly.
1752 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
1753 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
1754 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
1755 * callint.c (Fcall_interactively): Check arg count for overflow,
1756 to avoid potential buffer overrun. Use signed char, not 'int',
1757 for 'varies' array, so that we needn't bother to check its size
1758 calculation for overflow.
1759 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
1760 * eval.c (apply_lambda):
1761 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
1762 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
1763 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
1764
1765 * callint.c (Fcall_interactively): Don't use index var as event count.
1766
1767 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
1768 * mem-limits.h (SIZE): Remove; no longer used.
1769
1770 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
1771
1772 Remove unnecessary casts.
1773 * xterm.c (x_term_init):
1774 * xfns.c (x_set_border_pixel):
1775 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
1776 These aren't needed now that we assume ANSI C.
1777
1778 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
1779 It's more likely to cause problems (due to unsigned overflow)
1780 than to cure them.
1781
1782 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
1783
1784 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
1785
1786 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
1787
1788 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
1789
1790 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
1791
1792 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
1793
1794 GLYPH_CODE_FACE returns EMACS_INT, not int.
1795 * dispextern.h (merge_faces):
1796 * xfaces.c (merge_faces):
1797 * xdisp.c (get_next_display_element, next_element_from_display_vector):
1798 Don't assume EMACS_INT fits in int.
1799
1800 * character.h (CHAR_VALID_P): Remove unused parameter.
1801 * fontset.c, lisp.h, xdisp.c: All uses changed.
1802
1803 * editfns.c (Ftranslate_region_internal): Omit redundant test.
1804
1805 * fns.c (concat): Minor tuning based on overflow analysis.
1806 This doesn't fix any bugs. Use int to hold character, instead
1807 of constantly refetching from Emacs object. Use XFASTINT, not
1808 XINT, for value known to be a character. Don't bother comparing
1809 a single byte to 0400, as it's always less.
1810
1811 * floatfns.c (Fexpt):
1812 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
1813
1814 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
1815 for characters.
1816
1817 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
1818
1819 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
1820 Without this fix, on a 64-bit host (aset S 0 4294967386) would
1821 incorrectly succeed when S was a string, because 4294967386 was
1822 truncated before it was used.
1823
1824 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
1825 Otherwise, an out-of-range integer could cause undefined behavior
1826 on a 64-bit host.
1827
1828 * composite.c: Use int, not EMACS_INT, for characters.
1829 (fill_gstring_body, composition_compute_stop_pos): Use int, not
1830 EMACS_INT, for values that are known to be in character range.
1831 This doesn't fix any bugs but is the usual style inside Emacs and
1832 may generate better code on 32-bit machines.
1833
1834 Make sure a 64-bit char is never passed to ENCODE_CHAR.
1835 This is for reasons similar to the recent CHAR_STRING fix.
1836 * charset.c (Fencode_char): Check that character arg is actually
1837 a character. Pass an int to ENCODE_CHAR.
1838 * charset.h (ENCODE_CHAR): Verify that the character argument is no
1839 wider than 'int', as a compile-time check to prevent future regressions
1840 in this area.
1841
1842 * character.c (char_string): Remove unnecessary casts.
1843
1844 Make sure a 64-bit char is never passed to CHAR_STRING.
1845 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
1846 by silently ignoring the top 32 bits, allowing some values
1847 that were far too large to be valid characters.
1848 * character.h: Include <verify.h>.
1849 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
1850 arguments are no wider than unsigned, as a compile-time check
1851 to prevent future regressions in this area.
1852 * data.c (Faset):
1853 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
1854 (Fsubst_char_in_region):
1855 * fns.c (concat):
1856 * xdisp.c (decode_mode_spec_coding):
1857 Adjust to CHAR_STRING's new requirement.
1858 * editfns.c (Finsert_char, Fsubst_char_in_region):
1859 * fns.c (concat): Check that character args are actually
1860 characters. Without this test, these functions did the wrong
1861 thing with wildly out-of-range values on 64-bit hosts.
1862
1863 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
1864 These casts should not be needed on 32-bit hosts, either.
1865 * keyboard.c (read_char):
1866 * lread.c (Fload): Remove casts to unsigned.
1867
1868 * lisp.h (UNSIGNED_CMP): New macro.
1869 This fixes comparison bugs on 64-bit hosts.
1870 (ASCII_CHAR_P): Use it.
1871 * casefiddle.c (casify_object):
1872 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
1873 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
1874 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
1875 * dispextern.h (FACE_FROM_ID):
1876 * keyboard.c (read_char): Use UNSIGNED_CMP.
1877
1878 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
1879 not to EMACS_INT, to avoid GCC warning.
1880
1881 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
1882
1883 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
1884 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
1885 isn't needed on 32-bit machines.
1886
1887 * buffer.c (Fgenerate_new_buffer_name):
1888 Use EMACS_INT for count, not int.
1889 (advance_to_char_boundary): Return EMACS_INT, not int.
1890
1891 * data.c (Qcompiled_function): Now static.
1892
1893 * window.c (window_body_lines): Now static.
1894
1895 * image.c (gif_load): Rename local to avoid shadowing.
1896
1897 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
1898 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
1899 * alloc.c (make_save_value): Integer argument is now of type
1900 ptrdiff_t, not int.
1901 (mark_object): Use ptrdiff_t, not int.
1902 * lisp.h (pD): New macro.
1903 * print.c (print_object): Use it.
1904
1905 * alloc.c: Use EMACS_INT, not int, to count objects.
1906 (total_conses, total_markers, total_symbols, total_vector_size)
1907 (total_free_conses, total_free_markers, total_free_symbols)
1908 (total_free_floats, total_floats, total_free_intervals)
1909 (total_intervals, total_strings, total_free_strings):
1910 Now EMACS_INT, not int. All uses changed.
1911 (Fgarbage_collect): Compute overall total using a double, so that
1912 integer overflow is less likely to be a problem. Check for overflow
1913 when converting back to an integer.
1914 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
1915 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
1916 These were 'int' variables that could overflow on 64-bit hosts;
1917 they were never used, so remove them instead of repairing them.
1918 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
1919 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
1920 Previously, this ceilinged at INT_MAX, but that doesn't work on
1921 64-bit machines.
1922 (allocate_pseudovector): Don't use EMACS_INT when int would do.
1923
1924 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
1925 (allocate_vectorlike): Check for ptrdiff_t overflow.
1926 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
1927 when a (possibly-narrower) signed value would do just as well.
1928 We prefer using signed arithmetic, to avoid comparison confusion.
1929
1930 * alloc.c: Catch some string size overflows that we were missing.
1931 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
1932 for convenience in STRING_BYTES_MAX.
1933 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
1934 The definition here is exact; the one in lisp.h was approximate.
1935 (allocate_string_data): Check for string overflow. This catches
1936 some instances we weren't catching before. Also, it catches
1937 size_t overflow on (unusual) hosts where SIZE_MAX <= min
1938 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
1939 and ptrdiff_t and EMACS_INT are both 64 bits.
1940
1941 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
1942 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
1943 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
1944
1945 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
1946
1947 * alloc.c (Fmake_string): Check for out-of-range init.
1948
1949 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
1950
1951 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
1952
1953 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
1954
1955 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
1956 xg_get_default_scrollbar_width.
1957
1958 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
1959 (int_gtk_range_get_value): Move to the scroll bar part of the file.
1960 (style_changed_cb): Call update_theme_scrollbar_width and call
1961 x_set_scroll_bar_default_width and xg_frame_set_char_size for
1962 all frames (Bug#8505).
1963 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
1964 Call gtk_window_set_resizable if HAVE_GTK3.
1965 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
1966 and height if HAVE_GTK3 (Bug#8505).
1967 (scroll_bar_width_for_theme): New variable.
1968 (update_theme_scrollbar_width): New function.
1969 (xg_get_default_scrollbar_width): Move code to
1970 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
1971 (xg_initialize): Call update_theme_scrollbar_width.
1972
1973 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
1974
1975 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
1976
1977 2011-06-12 Martin Rudalics <rudalics@gmx.at>
1978
1979 * frame.c (make_frame): Call other_buffer_safely instead of
1980 other_buffer.
1981
1982 * window.c (temp_output_buffer_show): Call display_buffer with
1983 second argument Vtemp_buffer_show_specifiers and reset latter
1984 immediately after the call.
1985 (Vtemp_buffer_show_specifiers): New variable.
1986 (auto_window_vscroll_p, next_screen_context_lines)
1987 (Vscroll_preserve_screen_position): Remove leading asterisks from
1988 doc-strings.
1989
1990 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
1991
1992 Fix minor problems found by GCC 4.6.0 static checking.
1993 * buffer.c (Qclone_number): Remove for now, as it's unused.
1994 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
1995 (record_buffer): Remove unused local.
1996 * frame.c (other_visible_frames, frame_buffer_list): Now static.
1997 (set_frame_buffer_list): Remove; unused.
1998 * frame.h (other_visible_frames): Remove decl.
1999 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
2000 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
2001 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
2002 if HAVE_GPM.
2003 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
2004 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
2005 Define only if HAVE_GPM.
2006 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
2007 (update_hints_inhibit): Remove; never set. All uses removed.
2008 * widgetprv.h (emacsFrameClassRec): Remove decl.
2009 * window.c (delete_deletable_window): Now returns void, since it
2010 wasn't returning anything.
2011 (compare_window_configurations): Remove unused locals.
2012 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
2013 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
2014 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
2015 the same widths as pointers. This follows up on the 2011-05-06 patch.
2016 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
2017 * xterm.h: Likewise.
2018 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
2019
2020 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
2021
2022 * makefile.w32-in: Update dependencies.
2023 (LISP_H): Add lib/intprops.h.
2024
2025 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
2026
2027 * image.c (gif_load): Add animation frame delay to the metadata.
2028 (syms_of_image): Use DEFSYM. New symbol `delay'.
2029
2030 2011-06-11 Martin Rudalics <rudalics@gmx.at>
2031
2032 * window.c (delete_deletable_window): Re-add.
2033 (Fset_window_configuration): Rewrite to handle dead buffers and
2034 consequently deletable windows.
2035 (window_tree, Fwindow_tree): Remove. Supply functionality in
2036 window.el.
2037 (compare_window_configurations): Simplify code.
2038
2039 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
2040
2041 * image.c (imagemagick_load_image): Fix type mismatch.
2042 (Fimagemagick_types): Likewise.
2043
2044 * window.h (replace_buffer_in_windows): Declare.
2045
2046 2011-06-11 Martin Rudalics <rudalics@gmx.at>
2047
2048 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
2049 Qclone_number. Remove external declaration of Qdelete_window.
2050 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
2051 code.
2052 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer): Run
2053 Qbuffer_list_update_hook if allowed.
2054 (Fother_buffer): Rewrite doc-string. Major rewrite for new
2055 buffer list implementation.
2056 (other_buffer_safely): New function.
2057 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
2058 calls to replace_buffer_in_windows and
2059 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
2060 if allowed.
2061 (record_buffer): Inhibit quitting and rewrite using quittable
2062 functions. Run Qbuffer_list_update_hook if allowed.
2063 (Frecord_buffer, Funrecord_buffer): New functions.
2064 (switch_to_buffer_1, Fswitch_to_buffer): Remove. Move
2065 switch-to-buffer to window.el.
2066 (bury-buffer): Move to window.el.
2067 (Vbuffer_list_update_hook): New variable.
2068
2069 * lisp.h (other_buffer_safely): Add prototype in buffer.c
2070 section.
2071
2072 * window.h (resize_frame_windows): Move up in code.
2073 (Fwindow_frame): Remove EXFUN.
2074 (replace_buffer_in_all_windows): Remove prototype.
2075 (replace_buffer_in_windows_safely): Add prototype.
2076
2077 * window.c: Declare Qdelete_window static again. Move down
2078 declaration of select_count.
2079 (Fnext_window, Fprevious_window): Rewrite doc-strings.
2080 (Fother_window): Move to window.el.
2081 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
2082 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
2083 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
2084 window.el.
2085 (replace_buffer_in_windows): Implement by calling

2098
2099 * dispextern.h (struct image): Replace data member, whose int_val
2100 and ptr_val fields were not used by anything, with a single
2101 lisp_val object.
2102
2103 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
2104 (gif_clear_image, gif_load, imagemagick_load_image)

2528 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
2529 bidi_it->nchars is non-positive.
2530 (bidi_level_of_next_char): Don't try to lookup the cache for the
2531 next/previous character if nothing is cached there yet, or if we
2532 were just reseat()'ed to a new position.
2533
2534 * xdisp.c (set_cursor_from_row): Set start and stop points
2535 according to the row's direction when priming the loop that looks
2536 for the glyph on which to display cursor.
2537 (single_display_spec_intangible_p): Function deleted.
2538 (display_prop_intangible_p): Reimplement to call
2539 handle_display_spec instead of single_display_spec_intangible_p.
2540 Accept 3 additional arguments needed by handle_display_spec.
2541 This fixes incorrect cursor motion across display property with complex
2542 values: lists, `(when COND...)' forms, etc.
2543 (single_display_spec_string_p): Support property values that are
2544 lists with the argument STRING its top-level element.
2545 (display_prop_string_p): Fix the condition for processing a
2546 property that is a list to be consistent with handle_display_spec.
2547 (handle_display_spec): New function, refactored from the
2548 last portion of handle_display_prop.
2549 (compute_display_string_pos): Accept additional argument
2550 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
2551 value of a `display' property is a "replacing spec".
2552 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
2553 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
2554 the display property, but just return a value indicating whether
2555 the display property will replace the characters it covers.
2556 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
2557 frame_window_p members of struct bidi_it.
2558 (compute_display_string_pos, compute_display_string_end):
2559 New functions.
2560 (push_it): Accept second argument POSITION, where pop_it should
2561 jump to continue iteration.
2562 (reseat_1): Initialize bidi_it.disp_pos.
2563
2564 * keyboard.c (adjust_point_for_property): Adjust the call to
2565 display_prop_intangible_p to its new signature.
2566
2567 * dispextern.h (struct bidi_it): New member frame_window_p.
2568 (bidi_init_it): Update prototypes.
2569 (display_prop_intangible_p): Update prototype.
2570 (compute_display_string_pos, compute_display_string_end):
2571 Declare prototypes.
2572 (struct bidi_it): New members nchars and disp_pos. ch_len is now
2573 EMACS_INT.
2574
2575 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
2576
2577 Malloc failure behavior now depends on size of allocation.
2578 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
2579 * lisp.h: Change signatures accordingly.
2580 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
2581 All callers changed. (Bug#8762)
2582
2583 * gnutls.c: Use Emacs's memory allocators.
2584 Without this change, the gnutls library would invoke malloc etc.
2585 directly, which causes problems on non-SYNC_INPUT hosts, and which
2586 runs afoul of improving memory_full behavior. (Bug#8761)
2587 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
2588 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
2589 xfree instead of the default malloc, realloc, free.
2590 (Fgnutls_boot): No need to check for memory allocation failure,
2591 since xmalloc does that for us.
2592
2593 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
2594 * category.c (hash_get_category_set):
2595 * ccl.c (ccl_driver):
2596 * charset.c (Fdefine_charset_internal):
2597 * charset.h (struct charset.hash_index):

2599 (composition_gstring_put_cache):
2600 * composite.h (struct composition.hash_index):

2606 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
2607 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
2608 (Fsxhash, Fgethash, Fputhash, Fmaphash):
2609 * image.c (make_image, search_image_cache, lookup_image)
2610 (xpm_put_color_table_h):
2611 * lisp.h (struct Lisp_Hash_Table):
2612 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
2613 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
2614 for hashes and hash indexes, instead of 'unsigned' and 'int'.
2615 * alloc.c (allocate_vectorlike):
2616 Check for overflow in vector size calculations.
2617 * ccl.c (ccl_driver):
2618 Check for overflow when converting EMACS_INT to int.
2619 * fns.c, image.c: Remove unnecessary static decls that would otherwise
2620 need to be updated by these changes.
2621 * fns.c (make_hash_table, maybe_resize_hash_table):
2622 Check for integer overflow with large hash tables.
2623 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
2624 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
2625 (SXHASH_REDUCE): New macro.
2626 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
2627 Use it instead of discarding useful hash info with large hash values.
2628 (sxhash_float): New function.
2629 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
2630 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
2631 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
2632 Rewrite to use FIXNUM_BITS, as this simplifies things.
2633 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
2634 Adjust signatures to match updated version of code.
2635 (consing_since_gc): Now EMACS_INT, since a single hash table can
2636 use more than INT_MAX bytes.
2637
2638 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
2639
2640 Make it possible to build with GCC-4.6+ -O2 -flto.
2641
2642 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
2643
2644 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
2645
2646 * minibuf.c (get_minibuffer, read_minibuf_unwind):
2647 Call minibuffer-inactive-mode.
2648
2649 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
2650
2651 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
2652 Update dependencies.
2653
2654 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
2655
2656 * data.c (init_data): Remove code for UTS, this system is not
2657 supported anymore.
2658
2659 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
2660
2661 Don't force ./temacs to start in terminal mode.
2662
2663 * frame.c (make_initial_frame): Initialize faces in all cases, not
2664 only when CANNOT_DUMP is defined.
2665 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
2666
2667 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
2668
2669 * dispnew.c (add_window_display_history): Use const for the string
2670 pointer. Remove declaration, not needed.
2671
2672 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
2673
2674 Use 'inline', not 'INLINE'.
2675 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
2676 * alloc.c, fontset.c (INLINE): Remove.
2677 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
2678 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
2679 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
2680 * gmalloc.c (register_heapinfo): Use inline unconditionally.
2681 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
2682
2683 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
2684
2685 Make it possible to run ./temacs.
2686
2687 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
2688 syms_of_callproc does the same thing. Remove test for
2689 "initialized", do it in the caller.
2690 * emacs.c (main): Avoid calling set_initial_environment when dumping.
2691
2692 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
2693
2694 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
2695 (read_minibuf): Use get_minibuffer.
2696 (syms_of_minibuf): Use DEFSYM.
2697 (Qmetadata): New var.
2698 * data.c (Qbuffer): Don't make it static.
2699 (syms_of_data): Use DEFSYM.
2700
2701 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
2702
2703 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
2704 (CCL_CODE_MIN): New macro.
2705
2706 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
2707
2708 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
2709
2710 * eval.c (Qdebug): Now static.
2711 * lisp.h (Qdebug): Remove decl. This reverts a part of the
2712 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
2713 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
2714
2715 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
2716
2717 * image.c: Various fixes to ImageMagick code comments.
2718 (Fimagemagick_types): Doc fix.
2719
2720 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
2721
2722 Minor fixes prompted by GCC 4.6.0 warnings.
2723
2724 * xselect.c (converted_selections, conversion_fail_tag): Now static.
2725
2726 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
2727 (x_clipboard_manager_save_all): Move extern decl to ...
2728 * xterm.h: ... here, so that it can be checked for consistency.
2729
2730 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
2731
2732 * xselect.c (x_clipboard_manager_save_frame)
2733 (x_clipboard_manager_save_all): New functions.
2734 (Fx_clipboard_manager_save): Lisp function deleted.
2735
2736 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
2737 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
2738
2739 * xterm.h: Update prototype.
2740
2741 2011-05-28 William Xu <william.xwl@gmail.com>
2742
2743 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
2744 exiting (Bug#8239).
2745
2746 2011-05-28 Jim Meyering <meyering@redhat.com>
2747
2748 Avoid a sign-extension bug in crypto_hash_function.
2749 * fns.c (to_uchar): Define.
2750 (crypto_hash_function): Use it to convert some newly-signed
2751 variables to unsigned, to avoid sign-extension bugs. For example,
2752 without this change, (md5 "truc") would evaluate to
2753 45723a2aff78ff4fff7fff1114760e62 rather than the expected
2754 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
2755 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
2756
2757 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
2758
2759 Integer overflow fixes.
2760
2761 * dbusbind.c: Serial number integer overflow fixes.
2762 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
2763 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
2764 to hold a serial number that is too large for a fixnum.
2765 (Fdbus_method_return_internal, Fdbus_method_error_internal):
2766 Check for serial numbers out of range. Decode any serial number
2767 that was so large that it became a float. (Bug#8722)
2768
2769 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
2770 (Fdbus_call_method, Fdbus_call_method_asynchronously):
2771 Use XFASTINT rather than XUINT when numbers are nonnegative.
2772 (xd_append_arg, Fdbus_method_return_internal):
2773 (Fdbus_method_error_internal): Likewise. Also, for unsigned
2774 arguments, check that Lisp number is nonnegative, rather than
2775 silently wrapping negative numbers around. (Bug#8722)
2776 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
2777 (Bug#8722)
2778
2779 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
2780
2781 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
2782
2783 ccl: add integer overflow checks
2784 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
2785 (IN_INT_RANGE): New macros.
2786 (ccl_driver): Use them to check for integer overflow when
2787 decoding a CCL program. Many of the new checks are whether XINT (x)
2788 fits in int; it doesn't always, on 64-bit hosts. The new version
2789 doesn't catch all possible integer overflows, but it's an
2790 improvement. (Bug#8719)
2791
2792 * alloc.c (make_event_array): Use XINT, not XUINT.
2793 There's no need for unsigned here.
2794
2795 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
2796 This follows up to the 2011-05-06 change that substituted uintptr_t
2797 for EMACS_INT. This case wasn't caught back then.
2798
2799 Rework Fformat to avoid integer overflow issues.
2800 * editfns.c: Include <float.h> unconditionally, as it's everywhere
2801 now (part of C89). Include <verify.h>.
2802 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
2803 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
2804 (Fformat): Avoid the prepass trying to compute sizes; it was only
2805 approximate and thus did not catch overflow reliably. Instead, walk
2806 through the format just once, formatting and computing sizes as we go,
2807 checking for integer overflow at every step, and allocating a larger
2808 buffer as needed. Keep track separately whether the format is
2809 multibyte. Keep only the most-recently calculated precision, rather
2810 than them all. Record whether each argument has been converted to
2811 string. Use EMACS_INT, not int, for byte and char and arg counts.
2812 Support field widths and precisions larger than INT_MAX. Avoid
2813 sprintf's undefined behavior with conversion specifications such as %#d
2814 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
2815 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
2816 formatting out-of-range floating point numbers with int
2817 formats. (Bug#8668)
2818
2819 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
2820
2821 * data.c: Avoid integer truncation in expressions involving floats.
2822 * data.c: Include <intprops.h>.
2823 (arith_driver): When there's an integer overflow in an expression
2824 involving floating point, convert the integers to floating point
2825 so that the resulting value does not suffer from catastrophic
2826 integer truncation. For example, on a 64-bit host (* 4
2827 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
2828 Do not rely on undefined behavior after integer overflow.
2829
2830 merge count_size_as_multibyte, parse_str_to_multibyte
2831 * character.c, character.h (count_size_as_multibyte):
2832 Rename from parse_str_to_multibyte; all uses changed.
2833 Check for integer overflow.
2834 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
2835 since it's now a duplicate of the other. This is more of
2836 a character than a buffer op, so better that it's in character.c.
2837 * fns.c, print.c: Adjust to above changes.
2838
2839 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
2840
2841 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
2842
2843 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
2844
2845 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
2846 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
2847 (x_clipboard_manager_save): Now static.
2848 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
2849
2850 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
2851 (crypto_hash_function): Now static.
2852 Fix pointer signedness problems. Avoid unnecessary initializations.
2853
2854 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
2855
2856 * termhooks.h (Vselection_alist): Make it terminal-local.
2857
2858 * terminal.c (create_terminal): Initialize it.
2859
2860 * xselect.c: Support for clipboard managers.
2861 (Vselection_alist): Move to termhooks.h as terminal-local var.
2862 (LOCAL_SELECTION): New macro.
2863 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
2864 (symbol_to_x_atom): Remove gratuitous arg.
2865 (x_handle_selection_request, lisp_data_to_selection_data)
2866 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
2867 (x_own_selection, x_get_local_selection, x_convert_selection):
2868 New arg, specifying work frame. Use terminal-local Vselection_alist.
2869 (some_frame_on_display): Delete unused function.
2870 (Fx_own_selection_internal, Fx_get_selection_internal)
2871 (Fx_disown_selection_internal, Fx_selection_owner_p)
2872 (Fx_selection_exists_p): New optional frame arg.
2873 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
2874 (x_handle_selection_clear): Don't treat other terminals with the
2875 same keyboard specially. Use the terminal-local Vselection_alist.
2876 (x_clear_frame_selections): Use Frun_hook_with_args.
2877
2878 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
2879
2880 * xterm.h: Add support for those atoms.
2881
2882 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
2883
2884 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
2885 (converted_selections, conversion_fail_tag): New global variables.
2886 (x_selection_request_lisp_error): Free the above.
2887 (x_get_local_selection): Remove unnecessary code.
2888 (x_reply_selection_request): Args changed; handle arbitrary array
2889 of converted selections stored in converted_selections.
2890 Separate the XChangeProperty and SelectionNotify steps.
2891 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
2892 (x_convert_selection): New function.
2893 (x_handle_selection_event): Simplify.
2894 (x_get_foreign_selection): Don't ignore incoming requests while
2895 waiting for an answer; this will fail when we implement
2896 SAVE_TARGETS, and seems unnecessary anyway.
2897 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
2898 (Vx_sent_selection_functions): Doc fix.
2899
2900 2011-05-26 Leo Liu <sdl.web@gmail.com>

2905
2906 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
2907
2908 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
2909 for fringe update if it has periodic bitmap.
2910 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
2911 and fringe_bitmap_periodic_p.
2912
2913 * fringe.c (get_fringe_bitmap_data): New function.
2914 (draw_fringe_bitmap_1, update_window_fringes): Use it.
2915 (update_window_fringes): Record periodicity of fringe bitmap in glyph
2916 row. Mark glyph row for fringe update if periodicity changed.
2917
2918 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
2919 for fringe update unless it has periodic bitmap.
2920

2932 (Fmd5): Use crypto_hash_function.
2933 (syms_of_fns): Add Ssha1.
2934
2935 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
2936
2937 * gnutls.c: Remove unused macros.
2938 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
2939 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
2940 Remove macros that are defined and never used.
2941 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
2942
2943 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
2944
2945 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
2946 (Fx_get_selection_internal): Minor cleanup.
2947 (Fx_own_selection_internal): Rename arguments for consistency with
2948 select.el.
2949
2950 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
2951
2952 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
2953
2954 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
2955
2956 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
2957
2958 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2959
2960 * dispnew.c (scrolling_window): Don't exclude the case that the
2961 last enabled row in the desired matrix touches the bottom boundary.
2962
2963 2011-05-21 Glenn Morris <rgm@gnu.org>
2964
2965 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
2966 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
2967 and add some more files.
2968
2969 2011-05-20 Eli Zaretskii <eliz@gnu.org>
2970
2971 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
2972 report_file_error introduced by the change from 2011-05-07.
2973
2974 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
2975
2976 * systime.h (Time): Define only if emacs is defined.
2977 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
2978 where the include path doesn't have X11/X.h by default. See
2979 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
2980
2981 2011-05-20 Kenichi Handa <handa@m17n.org>
2982
2983 * composite.c (find_automatic_composition): Fix previous change.
2984
2985 2011-05-20 Glenn Morris <rgm@gnu.org>
2986
2987 * lisp.mk: New file, split from Makefile.in.
2988 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
2989 (shortlisp): Remove.
2990 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
2991
2992 2011-05-19 Glenn Morris <rgm@gnu.org>
2993
2994 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
2995 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
2996 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
2997 (lisp): Set the order to that of loadup.el.
2998 (shortlisp): Make it a copy of $lisp.
2999 (SOME_MACHINE_LISP): Remove.
3000 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
3001 Use just $shortlisp, not $SOME_MACHINE_LISP too.
3002
3003 2011-05-18 Kenichi Handa <handa@m17n.org>
3004
3005 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
3006 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
3007 (find_automatic_composition): Mostly rewrite for efficiency.
3008
3009 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
3010
3011 * makefile.w32-in: Update dependencies.
3012
3013 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
3014
3015 * menu.c: Include limits.h (fixes the MS-Windows build broken by
3016 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
3017
3018 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
3019
3020 Fix some integer overflow issues, such as string length overflow.
3021
3022 * insdel.c (count_size_as_multibyte): Check for string overflow.
3023
3024 * character.c (lisp_string_width): Check for string overflow.
3025 Use EMACS_INT, not int, for string indexes and lengths; in
3026 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
3027 the resulting string length overflows an EMACS_INT; instead,
3028 report a string overflow if no precision given. When checking for
3029 precision exhaustion, use a check that cannot possibly have
3030 integer overflow. (Bug#8675)
3031 * character.h (lisp_string_width): Adjust to new signature.
3032
3033 * alloc.c (string_overflow): New function.
3034 (Fmake_string): Use it. This doesn't change behavior, but saves
3035 a few bytes and will simplify future changes.
3036 * character.c (string_escape_byte8): Likewise.
3037 * lisp.h (string_overflow): New decl.
3038
3039 Fixups, following up to the user-interface timestamp change.
3040 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
3041 for UI timestamps, instead of unsigned long.
3042 * msdos.c (mouse_get_pos): Likewise.
3043 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
3044 * w32gui.h (Time): Define by including "systime.h" rather than by
3045 declaring it ourselves. (Bug#8664)
3046
3047 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
3048 * image.c (clear_image_cache): Likewise.
3049
3050 * term.c (term_mouse_position): Don't assume time_t wraparound.
3051
3052 Be more systematic about user-interface timestamps.
3053 Before, the code sometimes used 'Time', sometimes 'unsigned long',
3054 and sometimes 'EMACS_UINT', to represent these timestamps.
3055 This change causes it to use 'Time' uniformly, as that's what X uses.
3056 This makes the code easier to follow, and makes it easier to catch
3057 integer overflow bugs such as Bug#8664.
3058 * frame.c (Fmouse_position, Fmouse_pixel_position):
3059 Use Time, not unsigned long, for user-interface timestamps.
3060 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
3061 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
3062 * keyboard.h (last_event_timestamp): Likewise.
3063 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
3064 * menu.h (xmenu_show): Likewise.
3065 * term.c (term_mouse_position): Likewise.
3066 * termhooks.h (struct input_event.timestamp): Likewise.
3067 (struct terminal.mouse_position_hook): Likewise.
3068 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
3069 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
3070 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
3071 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
3072 what it was before.
3073 * menu.h, termhooks.h: Include "systime.h", for Time.
3074
3075 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
3076 Don't assume that the difference between two unsigned long values
3077 can fit into an integer. At this point, we know button_down_time
3078 <= event->timestamp, so the difference must be nonnegative, so
3079 there's no need to cast the result if double-click-time is
3080 nonnegative, as it should be; check that it's nonnegative, just in
3081 case. This bug is triggered when events are more than 2**31 ms
3082 apart (about 25 days). (Bug#8664)
3083
3084 * xselect.c (last_event_timestamp): Remove duplicate decl.
3085 (x_own_selection): Remove needless cast to unsigned long.
3086
3087 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
3088 that always fit in int. Use a sentinel instead of a counter, to
3089 avoid a temp and to allay GCC's concerns about possible int overflow.
3090 * frame.h (struct frame): Use int for menu_bar_items_used
3091 instead of EMACS_INT, since it always fits in int.
3092
3093 * menu.c (grow_menu_items): Check for int overflow.
3094
3095 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
3096
3097 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
3098 Before, the code was not consistent. These values cannot exceed
3099 2**31 - 1 so there's no need to make them unsigned.
3100 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
3101 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
3102 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
3103 as modifiers.
3104 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
3105
3106 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
3107 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
3108 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
3109 presumably because the widths might not match.
3110
3111 * window.c (size_window): Avoid needless test at loop start.
3112
3113 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
3114
3115 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
3116
3117 2011-05-12 Drew Adams <drew.adams@oracle.com>
3118
3119 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
3120
3121 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3122
3123 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
3124 `width' to `bar_area_x' and `bar_area_width', respectively.
3125 (x_scroll_run): Take account of fringe background extension.
3126
3127 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
3128 Rename local vars `left' and `width' to `bar_area_x' and
3129 `bar_area_width', respectively.
3130 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
3131 background extension.
3132
3133 2011-05-10 Jim Meyering <meyering@redhat.com>
3134
3135 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
3136
3137 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
3138
3139 * image.c (Finit_image_library): Return t for built-in image types,
3140 like pbm and xbm. (Bug#8640)
3141
3142 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
3143
3144 * w32menu.c (set_frame_menubar): Fix submenu allocation.
3145
3146 2011-05-07 Eli Zaretskii <eliz@gnu.org>
3147
3148 * w32console.c (Fset_screen_color): Doc fix.
3149 (Fget_screen_color): New function.
3150 (syms_of_ntterm): Defsubr it.
3151
3152 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
3153 unlink the temporary file if Fcall_process didn't create it in the
3154 first place.
3155 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
3156 child process will be redirected to a file specified with `:file'.
3157 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
3158 cue to call_process_cleanup not to close that handle.
3159
3160 2011-05-07 Ben Key <bkey76@gmail.com>
3161
3162 * makefile.w32-in: The bootstrap-temacs rule now makes use of
3163 one of two shell specific rules, either bootstrap-temacs-CMD or
3164 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
3165 to the previous implementation of the bootstrap-temacs rule.
3166 The bootstrap-temacs-CMD rule is similar to the previous
3167 implementation of the bootstrap-temacs rule except that it
3168 makes use of the ESC_CFLAGS variable instead of the CFLAGS
3169 variable.
3170
3171 These changes, along with some changes to nt/configure.bat,
3172 nt/gmake.defs, and nt/nmake.defs, are required to extend my
3173 earlier fix to add support for --cflags and --ldflags options
3174 that include quotes so that it works whether make uses cmd or
3175 sh as the shell.
3176
3177 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
3178
3179 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
3180 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
3181 is a constant.
3182 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
3183 a string. Handle both cases.
3184 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
3185 (Fdbus_register_method): Use Qinvalid_function.
3186
3187 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3188
3189 * makefile.w32-in: Update dependencies.
3190 (LISP_H): Add inttypes.h and stdin.h.
3191 (PROCESS_H): Add unistd.h.
3192
3193 2011-05-06 Eli Zaretskii <eliz@gnu.org>
3194
3195 * lread.c: Include limits.h (fixes the MS-Windows build broken by
3196 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
3197
3198 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
3199
3200 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
3201
3202 * term.c (vfatal): Remove stray call to va_end.
3203 It's not needed and the C Standard doesn't allow it here anyway.
3204
3205 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
3206 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
3207
3208 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
3209 bytes.
3210
3211 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
3212
3213 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3214
3215 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
3216
3217 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
3218
3219 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
3220
3221 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
3222 * charset.c (Fdefine_charset_internal): Don't initialize
3223 charset.code_space[15]. The value was garbage, on hosts with
3224 32-bit int (Bug#8600).
3225
3226 * lread.c (read_integer): Be more consistent with string-to-number.
3227 Use string_to_number to do the actual conversion; this avoids
3228 rounding errors and fixes some other screwups. Without this fix,
3229 for example, #x1fffffffffffffff was misread as -2305843009213693952.
3230 (digit_to_number): Move earlier, for benefit of read_integer.
3231 Return -1 if the digit is out of range for the base, -2 if it is
3232 not a digit in any supported base. (Bug#8602)
3233
3234 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
3235
3236 * dispnew.c (scrolling_window): Return 1 if we scrolled,
3237 to match comment at start of function. This also removes a
3238 GCC warning about overflow in a 32+64-bit port.
3239
3240 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
3241
3242 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
3243 Reported by Stefan Monnier in
3244 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
3245 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3246 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
3247
3248 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
3249 (EMACS_UINTPTR): Likewise, with uintptr_t.
3250
3251 * lisp.h: Prefer 64-bit EMACS_INT if available.
3252 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
3253 on 32-bit hosts that have 64-bit int, so that they can access
3254 large files.
3255 However, temporarily disable this change unless the temporary
3256 symbol WIDE_EMACS_INT is defined.
3257
3258 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
3259
3260 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
3261 This removes an assumption that EMACS_INT and long are the same
3262 width as pointers. The assumption is true for Emacs porting targets
3263 now, but we want to make other targets possible.
3264 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
3265 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
3266 In the rest of the code, change types of integers that hold casted
3267 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
3268 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
3269 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
3270 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
3271 No need to cast type when ORing.
3272 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
3273 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
3274 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
3275 assume EMACS_INT is the same width as char *.
3276 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
3277 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
3278 Remove no-longer-needed casts.
3279 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
3280 (xg_tool_bar_help_callback, xg_make_tool_item):
3281 Use EMACS_INTPTR to hold an integer
3282 that will be cast to void *; this can avoid a GCC warning
3283 if EMACS_INT is not the same width as void *.
3284 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
3285 * xdisp.c (display_echo_area_1, resize_mini_window_1):
3286 (current_message_1, set_message_1):
3287 Use a local to convert to proper width without a cast.
3288 * xmenu.c (dialog_selection_callback): Likewise.
3289
3290 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
3291 Also, don't assume VALBITS / RAND_BITS is less than 5,
3292 and don't rely on undefined behavior when shifting a 1 left into
3293 the sign bit.
3294 * lisp.h (get_random): Change signature to match.
3295
3296 * lread.c (hash_string): Use size_t, not int, for hash computation.
3297 Normally we prefer signed values; but hashing is special, because
3298 it's better to use unsigned division on hash table sizes so that
3299 the remainder is nonnegative. Also, size_t is the natural width
3300 for hashing into memory. The previous code used 'int', which doesn't
3301 retain enough info to hash well into very large tables.
3302 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
3303
3304 * dbusbind.c: Don't possibly lose pointer info when converting.
3305 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3306 Use XPNTR rather than XHASH, so that the high-order bits of
3307 the pointer aren't lost when converting through void *.
3308
3309 * eval.c (Fautoload): Don't double-shift a pointer.
3310
3311 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
3312
3313 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3314
3315 * gnutls.c (DEF_GNUTLS_FN):
3316 * image.c (DEF_IMGLIB_FN): Make function pointers static.
3317
3318 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
3319
3320 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
3321 marker. (Bug#8610)
3322
3323 2011-05-05 Eli Zaretskii <eliz@gnu.org>
3324
3325 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
3326 New version that can reserve upto 2GB of heap space.
3327
3328 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
3329
3330 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
3331
3332 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
3333
3334 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to

3448 rather than `XVECTOR (FOO)->size'.
3449
3450 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
3451 inttypes.h, as a gnulib replacement is used if it not available in
3452 system headers.

3461 will grow beyond MOST_POSITIVE_FIXNUM.
3462 (decode_coding_emacs_mule): Abort if there isn't enough place in
3463 charbuf for the composition carryover bytes. Reserve an extra
3464 space for up to 2 characters produced in a loop.
3465 (decode_coding_iso_2022): Abort if there isn't enough place in

3476 simple variables to record original value of point. (Bug#7952)
3477

3493 (command_loop_1): Run `delayed-warnings-hook'
3494 if Vdelayed_warnings_list is non-nil.
3495 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
3496 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
3497
3498 2011-04-28 Eli Zaretskii <eliz@gnu.org>
3499
3500 * doprnt.c (doprnt): Don't return value smaller than the buffer
3501 size if the message was truncated. (Bug#8545).
3502
3503 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3504
3505 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
3506 (Fx_window_property): #if-0 the whole functions, not just the bodies.
3507
3508 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3509
3510 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
3511
3512 2011-04-27 Juanma Barranquero <lekktu@gmail.com>

3516 2011-04-27 Eli Zaretskii <eliz@gnu.org>
3517
3518 Improve `doprnt' and its usage. (Bug#8545)
3519 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
3520 `format_end'. Remove support for %l as a conversion specifier.
3521 Don't use xrealloc. Improve diagnostics when the %l size modifier
3522 is used. Update the commentary.
3523
3524 * eval.c (verror): Simplify calculation of size_t.
3525
3526 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
3527 messages.
3528
3529 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
3530
3531 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
3532 change.
3533
3534 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3535
3536 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
3537 This makes this file independent of the recent pseudovector change.
3538
3539 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
3540
3541 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
3542
3543 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
3544 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
3545 Remove unused local.
3546 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
3547
3548 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
3549 GCC 4.6.0 optimizes based on type-based alias analysis.
3550 For example, if b is of type struct buffer * and v of type struct
3551 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
3552 != &v->size, and therefore "v->size = 1; b->size = 2; return
3553 v->size;" must therefore return 1. This assumption is incorrect
3554 for Emacs, since it type-puns struct Lisp_Vector * with many other
3555 types. To fix this problem, this patch adds a new type struct
3556 vectorlike_header that documents the constraints on layout of vectors
3557 and pseudovectors, and helps optimizing compilers not get fooled
3558 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
3559 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
3560 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
3561 the size member.
3562 (XSETPVECTYPE): Rewrite in terms of new macro.
3563 (XSETPVECTYPESIZE): New macro, specifying both type and size.
3564 This is a bit clearer, and further avoids the possibility of
3565 undesirable aliasing.
3566 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
3567 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
3568 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
3569 since Lisp_Subr is a special case (no "next" field).
3570 (ASIZE): Now uses header.size rather than size.
3571 All previous uses of XVECTOR (foo)->size replaced to use this macro,
3572 to avoid the hassle of writing XVECTOR (foo)->header.size.
3573 (struct vectorlike_header): New type.
3574 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
3575 object, to help avoid aliasing.
3576 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
3577 (SUBRP): Likewise, since Lisp_Subr is a special case.
3578 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
3579 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
3580 (struct Lisp_Hash_Table): Combine first two members into a single
3581 struct vectorlike_header member. All uses of "size" and "next" members
3582 changed to be "header.size" and "header.next".
3583 * buffer.h (struct buffer): Likewise.
3584 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
3585 * frame.h (struct frame): Likewise.
3586 * process.h (struct Lisp_Process): Likewise.
3587 * termhooks.h (struct terminal): Likewise.
3588 * window.c (struct save_window_data, struct saved_window): Likewise.
3589 * window.h (struct window): Likewise.
3590 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
3591 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
3592 * buffer.c (init_buffer_once): Likewise.
3593 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
3594 special case.
3595 * process.c (Fformat_network_address): Use local var for size,
3596 for brevity.
3597
3598 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
3599
3600 Make the Lisp reader and string-to-float more consistent (Bug#8525)
3601 * data.c (atof): Remove decl; no longer used or needed.
3602 (digit_to_number): Move to lread.c.
3603 (Fstring_to_number): Use new string_to_number function, to be
3604 consistent with how the Lisp reader treats infinities and NaNs.
3605 Do not assume that floating-point numbers represent EMACS_INT
3606 without losing information; this is not true on most 64-bit hosts.
3607 Avoid double-rounding errors, by insisting on integers when
3608 parsing non-base-10 numbers, as the documentation specifies.
3609 * lisp.h (string_to_number): New decl, replacing ...
3610 (isfloat_string): Remove.
3611 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
3612 (read1): Do not accept +. and -. as integers; this
3613 appears to have been a coding error. Similarly, do not accept
3614 strings like +-1e0 as floating point numbers. Do not report
3615 overflow for integer overflows unless the base is not 10 which
3616 means we have no simple and reliable way to continue.
3617 Break out the floating-point parsing into a new
3618 function string_to_number, so that Fstring_to_number parses
3619 floating point numbers consistently with the Lisp reader.
3620 (digit_to_number): Move here from data.c. Make it static inline.
3621 (E_CHAR, EXP_INT): Remove, replacing with ...
3622 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
3623 (string_to_number): New function, replacing isfloat_string.
3624 This function checks for valid syntax and produces the resulting
3625 Lisp float number too. Rework it so that string-to-number
3626 no longer mishandles examples like "1.0e+". Use strtoumax,
3627 so that overflow for non-base-10 numbers is reported only when
3628 there's no portable and simple way to convert to floating point.
3629
3630 * textprop.c (set_text_properties_1): Rewrite for clarity,
3631 and to avoid GCC warning about integer overflow.
3632
3633 * intervals.h (struct interval): Use EMACS_INT for members
3634 where EMACS_UINT might cause problems. See
3635 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
3636 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
3637 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
3638 All uses changed.
3639 (offset_intervals): Tell GCC not to worry about length overflow
3640 when negating a negative length.
3641
3642 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
3643 (overrun_check_free): Likewise.
3644
3645 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
3646 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
3647 word size.
3648
3649 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3650 (gnutls_make_error): Rename local to avoid shadowing.
3651 (gnutls_emacs_global_deinit): ifdef out; not used.
3652 (Fgnutls_boot): Use const for pointer to readonly storage.
3653 Comment out unused local. Fix pointer signedness problems.
3654
3655 * lread.c (openp): Don't stuff size_t into an 'int'.
3656 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
3657 about possible signed overflow.
3658
3659 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3660 (GDK_KEY_g): Don't define if already defined.
3661 (xg_prepare_tooltip): Avoid pointer signedness problem.
3662 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
3663
3664 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
3665 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
3666
3667 * xfns.c (Fx_window_property): Simplify a bit,
3668 to make a bit faster and to avoid GCC 4.6.0 warning.
3669 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
3670
3671 * fns.c (internal_equal): Don't assume size_t fits in int.
3672
3673 * alloc.c (compact_small_strings): Tighten assertion a little.
3674
3675 Replace pEd with more-general pI, and fix some printf arg casts.
3676 * lisp.h (pI): New macro, generalizing old pEd macro to other
3677 conversion specifiers. For example, use "...%"pI"d..." rather
3678 than "...%"pEd"...".
3679 (pEd): Remove. All uses replaced with similar uses of pI.
3680 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
3681 * alloc.c (check_pure_size): Don't overflow by converting size to int.
3682 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
3683 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
3684 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
3685 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
3686 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
3687 64-bit hosts.
3688 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
3689 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
3690 * print.c (safe_debug_print, print_object): Likewise.
3691 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
3692 to int.
3693 Use pI instead of if-then-else-abort. Use %p to avoid casts,
3694 avoiding the 0 flag, which is not portable.
3695 * process.c (Fmake_network_process): Use pI to avoid cast.
3696 * region-cache.c (pp_cache): Likewise.
3697 * xdisp.c (decode_mode_spec): Likewise.
3698 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
3699 behavior on 64-bit hosts with printf arg.
3700 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
3701 (x_stop_queuing_selection_requests): Likewise.
3702 (x_get_window_property): Don't truncate byte count to an 'int'
3703 when tracing.
3704
3705 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
3706 here, since it parses constructs like leading '-' and spaces,
3707 which are not wanted; and it overflows with large numbers.
3708 Instead, simply match F[0-9]+, which is what is wanted anyway.
3709
3710 * alloc.c: Remove unportable assumptions about struct layout.
3711 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
3712 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
3713 (allocate_vectorlike, make_pure_vector): Use the new macros,
3714 plus offsetof, to remove unportable assumptions about struct layout.
3715 These assumptions hold on all porting targets that I know of, but
3716 they are not guaranteed, they're easy to remove, and removing them
3717 makes further changes easier.
3718
3719 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
3720 This doesn't fix a bug but makes the code clearer.
3721 (string_overrun_cookie): Now const. Use initializers that
3722 don't formally overflow signed char, to avoid warnings.
3723 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
3724 can cause Emacs to crash when string overrun checking is enabled.
3725 (allocate_buffer): Don't assume sizeof (struct buffer) is a

4552 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
4553
4554 * editfns.c (Fformat): Remove unreachable code.
4555
4556 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
4557
4558 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
4559 change. (Bug#8496)
4560
4561 2011-04-13 Eli Zaretskii <eliz@gnu.org>
4562
4563 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
4564 when at ZV. (Bug#8487)
4565
4566 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
4567
4568 * charset.c (Fclear_charset_maps): Use xfree instead of free.
4569 (Bug#8437)
4570 * keyboard.c (parse_tool_bar_item): Likewise.
4571 * sound.c (sound_cleanup, alsa_close): Likewise.
4572 * termcap.c (tgetent): Likewise.
4573 * xfns.c (x_default_font_parameter): Likewise.
4574 * xsettings.c (read_and_apply_settings): Likewise.
4575
4576 * alloc.c (overrun_check_malloc, overrun_check_realloc)
4577 (overrun_check_free): Protoize.
4578
4579 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
4580
4581 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
4582 since callers should never pass a negative size.
4583 Change the signature to match that of plain 'read' and 'write'; see
4584 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
4585 * lisp.h: Update prototypes of emacs_write and emacs_read.
4586
4587 2011-04-11 Eli Zaretskii <eliz@gnu.org>
4588
4589 * xdisp.c (redisplay_window): Don't try to determine the character
4590 position of the scroll margin if the window start point w->startp
4591 is outside the buffer's accessible region. (Bug#8468)
4592
4593 2011-04-10 Eli Zaretskii <eliz@gnu.org>
4594
4595 Fix write-region and its subroutines for buffers > 2GB.
4596 * fileio.c (a_write, e_write): Modify declaration of arguments and
4597 local variables to support buffers larger than 2GB.
4598 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
4599
4600 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
4601 argument, local variables, and return value.
4602
4603 * lisp.h: Update prototypes of emacs_write and emacs_read.
4604
4605 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
4606
4607 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
4608
4609 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
4610
4611 Fix more problems found by GCC 4.6.0's static checks.
4612
4613 * xdisp.c (vmessage): Use a better test for character truncation.
4614
4615 * charset.c (load_charset_map): <, not <=, for optimization,
4616 and to avoid potential problems with integer overflow.
4617 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
4618 * casetab.c (set_identity, shuffle): Likewise.
4619 * editfns.c (Fformat): Likewise.
4620 * syntax.c (skip_chars): Likewise.
4621
4622 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
4623 This also lets GCC 4.6.0 generate slightly better loop code.
4624
4625 * callint.c (Fcall_interactively): <, not <=, for optimization.
4626 (Fcall_interactively): Count the number of arguments produced,
4627 not the number of arguments given. This is simpler and lets GCC
4628 4.6.0 generate slightly better code.
4629
4630 * ftfont.c: Distingish more carefully between FcChar8 and char.
4631 The previous code passed unsigned char * to a functions like
4632 strlen and xstrcasecmp that expect char *, which does not
4633 conform to the C standard.
4634 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
4635 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
4636 char * when the C standard requires it.
4637
4638 * keyboard.c (read_char): Remove unused var.
4639
4640 * eval.c: Port to Windows vsnprintf (Bug#8435).
4641 Include <limits.h>.
4642 (SIZE_MAX): Define if the headers do not.
4643 (verror): Do not give up if vsnprintf returns a negative count.
4644 Instead, grow the buffer. This ports to Windows vsnprintf, which
4645 does not conform to C99. Problem reported by Eli Zaretskii.
4646 Also, simplify the allocation scheme, by avoiding the need for
4647 calling realloc, and removing the ALLOCATED variable.
4648
4649 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
4650
4651 Remove invocations of doprnt, as Emacs now uses vsnprintf.
4652 But keep the doprint source code for now, as we might revamp it
4653 and use it again (Bug#8435).
4654 * lisp.h (doprnt): Remove.
4655 * Makefile.in (base_obj): Remove doprnt.o.
4656 * deps.mk (doprnt.o): Remove.
4657
4658 error: Print 32- and 64-bit integers portably (Bug#8435).
4659 Without this change, on typical 64-bit hosts error ("...%d...", N)
4660 was used to print both 32- and 64-bit integers N, which relied on
4661 undefined behavior.
4662 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
4663 New macro.
4664 * lisp.h (error, verror): Mark as printf-like functions.
4665 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
4666 Report overflow in size calculations when allocating printf buffer.
4667 Do not truncate output string at its first null byte.
4668 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
4669 Truncate the output at a character boundary, since vsnprintf does not
4670 do that.
4671 * charset.c (check_iso_charset_parameter): Convert internal
4672 character to string before calling 'error', since %c now has the
4673 printf meaning.
4674 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
4675 overflow when computing char to be passed to 'error'. Do not
4676 pass Lisp_Object to 'error'; pass the integer instead.
4677 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
4678 formatted with plain %d.
4679
4680 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
4681
4682 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
4683
4684 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
4685
4686 * xterm.c (x_catch_errors): Remove duplicate declaration.
4687
4688 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
4689
4690 * xdisp.c, lisp.h (message_nolog): Remove; unused.
4691
4692 2011-04-10 Jim Meyering <meyering@redhat.com>
4693
4694 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
4695 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
4696 return ssize_t not "int", and use size_t as the buffer length.
4697 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
4698 * gnutls.h: Update declarations.
4699 * process.c (read_process_output): Use ssize_t, to match.
4700 (send_process): Likewise.
4701
4702 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4703
4704 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
4705
4706 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4707
4708 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
4709 Use unsigned char, to match FcChar8 type definition.
4710
4711 * xterm.c (handle_one_xevent):
4712 * xmenu.c (create_and_show_popup_menu):
4713 * xselect.c (x_decline_selection_request)
4714 (x_reply_selection_request): Avoid type-punned deref of X events.
4715
4716 2011-04-09 Eli Zaretskii <eliz@gnu.org>
4717
4718 Fix some uses of `int' instead of EMACS_INT.
4719 * search.c (string_match_1, fast_string_match)
4720 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
4721 (scan_buffer, find_next_newline_no_quit)
4722 (find_before_next_newline, search_command, Freplace_match)
4723 (Fmatch_data): Make some `int' variables be EMACS_INT.
4724
4725 * xdisp.c (display_count_lines): 3rd argument and return value now
4726 EMACS_INT. All callers changed.
4727 (pint2hrstr): Last argument is now EMACS_INT.
4728
4729 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
4730 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
4731 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
4732 (decode_coding_utf_16, decode_coding_emacs_mule)
4733 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
4734 (decode_coding_ccl, decode_coding_charset)
4735 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
4736 (decode_coding_iso_2022, decode_coding_emacs_mule)
4737 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
4738 <char_offset, last_offset>: Declare EMACS_INT.
4739 (encode_coding_utf_8, encode_coding_utf_16)
4740 (encode_coding_emacs_mule, encode_invocation_designation)
4741 (encode_designation_at_bol, encode_coding_iso_2022)
4742 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
4743 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
4744 Declare EMACS_INT.
4745 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
4746 (encode_invocation_designation): Last argument P_NCHARS is now
4747 EMACS_INT.
4748 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
4749 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
4750
4751 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
4752 All users changed.
4753
4754 * ccl.c (Fccl_execute_on_string): Declare some variables
4755 EMACS_INT.
4756
4757 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
4758
4759 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
4760
4761 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
4762
4763 * process.c (Fformat_network_address): Doc fix.
4764
4765 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
4766
4767 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
4768
4769 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
4770
4771 * keyboard.c (read_char): Call Lisp function help-form-show,
4772 instead of using internal_with_output_to_temp_buffer.
4773 (Qhelp_form_show): New var.
4774 (syms_of_keyboard): Use DEFSYM macro.
4775
4776 * print.c (internal_with_output_to_temp_buffer): Function deleted.
4777
4778 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
4779
4780 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
4781
4782 * process.c (Flist_processes): Remove to Lisp.
4783 (list_processes_1): Delete.
4784
4785 2011-04-06 Eli Zaretskii <eliz@gnu.org>
4786
4787 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
4788
4789 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
4790
4791 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
4792
4793 Fix more problems found by GCC 4.6.0's static checks.
4794
4795 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
4796
4797 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
4798
4799 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
4800
4801 * xdisp.c (vmessage): Mark as a printf-like function.
4802
4803 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
4804
4805 * sound.c (sound_warning): Don't crash if arg contains a printf format.
4806
4807 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
4808 printf-like functions.
4809 (tiff_load): Add casts to remove these marks before passing them
4810 to system-supplied API.
4811
4812 * eval.c (Fsignal): Remove excess argument to 'fatal'.
4813
4814 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
4815 This avoids several warnings with gcc -Wstrict-overflow.
4816 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
4817 directly, rather than having caller test rule sign. This avoids
4818 some unnecessary tests.
4819 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
4820 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
4821 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
4822
4823 * xfont.c (xfont_text_extents): Remove var that was set but not used.
4824 (xfont_open): Avoid unnecessary tests.
4825
4826 * composite.c (composition_gstring_put_cache): Use unsigned integer.

4833 (COMPOSITION_DECODE_RULE): Use it.
4834 * composite.c (get_composition_id): Remove unused local vars,
4835 by using the new macro.
4836
4837 * textprop.c (set_text_properties_1): Change while to do-while,
4838 since the condition is always true at first.
4839
4840 * intervals.c (graft_intervals_into_buffer): Mark var as used.
4841 (interval_deletion_adjustment): Return unsigned value.
4842 All uses changed.
4843
4844 * process.c (list_processes_1, create_pty, read_process_output):
4845 (exec_sentinel): Remove vars that were set but not used.
4846 (create_pty): Remove unnecessary "volatile"s.
4847 (Fnetwork_interface_info): Avoid possibility of int overflow.
4848 (read_process_output): Do adaptive read buffering even if carryover.
4849 (read_process_output): Simplify nbytes computation if buffered.
4850
4851 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
4852
4853 * syntax.c (scan_words): Remove var that was set but not used.
4854 (update_syntax_table): Use unsigned instead of int.
4855
4856 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
4857 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
4858 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
4859
4860 * print.c (print_error_message): Avoid int overflow.
4861
4862 * font.c (font_list_entities): Redo for clarity,
4863 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
4864
4865 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
4866 (font_score): Avoid potential overflow in diff calculation.
4867
4868 * fns.c (substring_both): Remove var that is set but not used.
4869 (sxhash): Redo loop for clarity and to avoid wraparound warning.
4870
4871 * eval.c (funcall_lambda): Rename local to avoid shadowing.
4872
4873 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
4874 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
4875 can always succeed if overflow has undefined behavior.
4876
4877 * search.c (boyer_moore, wordify): Remove vars set but not used.
4878 (wordify): Omit three unnecessary tests.
4879
4880 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
4881 All callers changed. This avoids the need for an unused var.
4882
4883 * casefiddle.c (casify_region): Remove var that is set but not used.
4884
4885 * dired.c (file_name_completion): Remove var that is set but not used.
4886
4887 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
4888

4890 (Finsert_file_contents): Remove unnecessary code checking fd.
4891
4892 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
4893 Check for integer overflow on size calculations.
4894
4895 * buffer.c (Fprevious_overlay_change): Remove var that is set
4896 but not used.
4897
4898 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
4899 Remove vars that are set but not used.
4900 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
4901 (timer_check_2): Mark vars as initialized.
4902
4903 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
4904
4905 * image.c (lookup_image): Remove var that is set but not used.
4906 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
4907
4908 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
4909 that are set but not used.
4910
4911 * xfns.c (make_invisible_cursor): Don't return garbage
4912 if XCreateBitmapFromData fails (Bug#8410).
4913
4914 * xselect.c (x_get_local_selection, x_handle_property_notify):
4915 Remove vars that are set but not used.
4916
4917 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

4921 Remove var that is set but not used.
4922 (scroll_bar_windows_size): Now size_t, not int.
4923 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
4924 Check for overflow.
4925
4926 * xfaces.c (realize_named_face): Remove vars that are set but not used.
4927 (map_tty_color) [!defined MSDOS]: Likewise.
4928
4929 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
4930
4931 * coding.c: Remove vars that are set but not used.
4932 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
4933 All callers changed.
4934 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
4935 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
4936 (decode_coding_charset): Remove vars that are set but not used.
4937
4938 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
4939 that is set but not used.
4940
4941 * print.c (print_object): Remove var that is set but not used.
4942
4943 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
4944 The gnulib version avoids calling malloc in the usual case,
4945 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
4946 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
4947 * filelock.c (current_lock_owner): Likewise.
4948 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
4949 * sysdep.c: Include allocator.h, careadlinkat.h.
4950 (emacs_no_realloc_allocator): New static constant.
4951 (emacs_readlink): New function.
4952 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
4953 ../lib/careadlinkat.h.
4954
4955 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
4956
4957 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
4958 first non-nil return value).
4959
4960 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
4961
4962 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
4963 if not defined (Bug#8403).
4964
4965 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
4966
4967 * xdisp.c (display_count_lines): Remove parameter `start',
4968 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
4969 (get_char_face_and_encoding): Remove parameter `multibyte_p',

4993
4994 Add lexical binding.
4995

4999
5000 * lread.c (lisp_file_lexically_bound_p): New function.
5001 (Fload): Bind Qlexical_binding.
5002 (readevalloop): Remove `evalfun' arg.
5003 Bind Qinternal_interpreter_environment.
5004 (Feval_buffer): Bind Qlexical_binding.
5005 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
5006 Mark as dynamic.
5007 (syms_of_lread): Declare `lexical-binding'.
5008
5009 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
5010
5011 * keyboard.c (eval_dyn): New fun.
5012 (menu_item_eval_property): Use it.
5013
5014 * image.c (parse_image_spec): Use Ffunctionp.
5015
5016 * fns.c (concat, mapcar1): Accept byte-code-functions.
5017
5018 * eval.c (Fsetq): Handle lexical vars.
5019 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
5020 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
5021 (FletX, Flet): Obey lexical binding.
5022 (Fcommandp): Handle closures.
5023 (Feval): New `lexical' arg.
5024 (eval_sub): New function extracted from Feval. Use it almost
5025 everywhere where Feval was used. Look up vars in lexical env.
5026 Handle closures.
5027 (Ffunctionp): Move from subr.el.
5028 (Ffuncall): Handle closures.
5029 (apply_lambda): Remove `eval_flags'.
5030 (funcall_lambda): Handle closures and new byte-code-functions.
5031 (Fspecial_variable_p): New function.
5032 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
5033 but without exporting it to Lisp.
5034

5036 * data.c (Finteractive_form): Handle closures.
5037
5038 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
5039 interactive spec.
5040
5041 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
5042 New byte-codes.
5043 (exec_byte_code): New function extracted from Fbyte_code to handle new
5044 calling convention for byte-code-functions. Add new byte-codes.
5045
5046 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
5047
5048 * alloc.c (Fmake_symbol): Init new `declared_special' field.
5049
5050 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
5051
5052 * xdisp.c (redisplay_internal): Fix prototype.
5053
5054 2011-03-31 Eli Zaretskii <eliz@gnu.org>
5055
5056 * xdisp.c (SCROLL_LIMIT): New macro.
5057 (try_scrolling): Use it when setting scroll_limit.
5058 Limit scrolling to 100 screen lines.
5059 (redisplay_window): Even when falling back on "recentering",
5060 position point in the window according to scroll-conservatively,
5061 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
5062
5063 (try_scrolling): When point is above the window, allow searching
5064 as far as scroll_max, or one screenful, to compute vertical
5065 distance from PT to the scroll margin position. This prevents
5066 try_scrolling from unnecessarily failing when
5067 scroll-conservatively is set to a value slightly larger than the
5068 window height. Clean up the case of PT below the margin at bottom
5069 of window: scroll_max can no longer be INT_MAX. When aggressive
5070 scrolling is in use, don't let point enter the opposite scroll
5071 margin as result of the scroll.
5072 (syms_of_xdisp) <scroll-conservatively>: Document the
5073 threshold of 100 lines for never-recentering scrolling.

5081 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5082 (redisplay_internal): Remove parameter `preserve_echo_area',
5083 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
5084
5085 * indent.c (Fvertical_motion):
5086 * window.c (window_scroll_pixel_based, Frecenter):
5087 Don't pass `need_y_p' to `move_it_by_lines'.
5088
5089 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
5090
5091 * eval.c (struct backtrace): Don't cheat with negative numbers, but do

5101 binding" message (bug#7967).
5102
5103 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
5104
5105 Fix more problems found by GCC 4.6.0's static checks.
5106
5107 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
5108 Remove unused local var.
5109
5110 * editfns.c (Fmessage_box): Remove unused local var.
5111
5112 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
5113 (note_mode_line_or_margin_highlight, note_mouse_highlight):
5114 Omit unused local vars.
5115 * window.c (shrink_windows): Omit unused local var.
5116 * menu.c (digest_single_submenu): Omit unused local var.
5117 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
5118 Omit unused local var.
5119
5120 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
5121 Don't assume string length fits in int.
5122 (keyremap_step, read_key_sequence): Use size_t for sizes.
5123 (read_key_sequence): Don't check last_real_key_start redundantly.
5124
5125 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
5126 instead of alloca (Bug#8344).
5127
5128 * eval.c (Fbacktrace): Don't assume nargs fits in int.
5129 (Fbacktrace_frame): Don't assume nframes fits in int.
5130
5131 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
5132
5133 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
5134 concerns.
5135
5136 * term.c (produce_glyphless_glyph): Remove unnecessary test.
5137
5138 * cm.c (calccost): Turn while-do into do-while, for clarity.
5139
5140 * keyboard.c (syms_of_keyboard): Use the same style as later
5141 in this function when indexing through an array. This also
5142 works around GCC bug 48267.
5143
5144 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
5145

5149 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
5150
5151 * keyboard.c, keyboard.h (num_input_events): Now size_t.
5152 This avoids undefined behavior on integer overflow, and is a bit
5153 more convenient anyway since it is compared to a size_t variable.
5154
5155 Variadic C functions now count arguments with size_t, not int.
5156 This avoids an unnecessary limitation on 64-bit machines, which
5157 caused (substring ...) to crash on large vectors (Bug#8344).

5166 (funcall_lambda, mark_backtrace): Likewise.
5167 * fns.c (concat): Likewise.
5168 * frame.c (x_set_frame_parameters): Likewise.
5169 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
5170 0 if not found, not -1. All callers changed.
5171
5172 * alloc.c (garbage_collect): Don't assume stack size fits in int.
5173 (stack_copy_size): Now size_t, not int.
5174 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

5199 Vcommand_hook_internal.

5380 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
5381 Use Frun_hooks.
5382 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
5383 unconditionnaly since it does the check itself.
5384
5385 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
5386
5387 Fix more problems found by GCC 4.5.2's static checks.
5388
5389 * coding.c (encode_coding_raw_text): Avoid unnecessary test
5390 the first time through the loop, since we know p0 < p1 then.
5391 This also avoids a gcc -Wstrict-overflow warning.
5392
5393 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
5394 leading to a memory leak, possible in functions like
5395 load_charset_map_from_file that can allocate an unbounded number
5396 of objects (Bug#8318).
5397
5398 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
5399 that could (at least in theory) be that large.
5400
5401 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
5402 This is less likely to overflow, and avoids undefined behavior if
5403 overflow does occur. All callers changed. Use strtoul to scan
5404 for the unsigned long integer.
5405 (pint2hrstr): Simplify and tune code slightly.
5406 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
5407
5408 * scroll.c (do_scrolling): Work around GCC bug 48228.
5409 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
5410
5411 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
5412 This also avoids a warning with gcc -Wstrict-overflow.
5413 (validate_x_resource_name): Simplify count usage.
5414 This also avoids a warning with gcc -Wstrict-overflow.
5415
5416 * fileio.c (Fcopy_file): Report error if fchown or fchmod
5417 fail (Bug#8306).
5418
5419 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
5420
5421 * process.c (Fmake_network_process): Use socklen_t, not int,
5422 where POSIX says socklen_t is required in portable programs.
5423 This fixes a porting bug on hosts like 64-bit HP-UX, where
5424 socklen_t is wider than int (Bug#8277).
5425 (Fmake_network_process, server_accept_connection):
5426 (wait_reading_process_output, read_process_output):
5427 Likewise.
5428
5429 * process.c: Rename or move locals to avoid shadowing.
5430 (list_processes_1, Fmake_network_process):
5431 (read_process_output_error_handler, exec_sentinel_error_handler):

5433 (Fmake_network_process): Define label "retry_connect" only if needed.
5434 (Fnetwork_interface_info): Fix pointer signedness.
5435 (process_send_signal): Add cast to avoid pointer signedness problem.
5436 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
5437 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
5438
5439 Make tparam.h and terminfo.c consistent.
5440 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
5441 Include tparam.h instead, since it declares them.
5442 * cm.h (PC): Remove extern decl; tparam.h now does this.
5443 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
5444 * terminfo.c: Include tparam.h, to check interfaces.
5445 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
5446 (tparam): Adjust signature to match interface in tparam.h;
5447 this removes some undefined behavior. Check that outstring and len
5448 are zero, which they always are with Emacs.
5449 * tparam.h (PC, BC, UP): New extern decls.
5450
5451 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
5452 (xftfont_open): Rename locals to avoid shadowing.
5453
5454 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
5455 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
5456 (OTF_TAG_SYM): Omit macro if not needed.
5457 (ftfont_list): Remove unused local.

5459 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
5460 Rename locals to avoid shadowing.
5461
5462 * xfont.c (xfont_list_family): Mark var as initialized.
5463
5464 * xml.c (make_dom): Now static.
5465
5466 * composite.c (composition_compute_stop_pos): Rename local to
5467 avoid shadowing.
5468 (composition_reseat_it): Remove unused locals.
5469 (find_automatic_composition, composition_adjust_point): Likewise.
5470 (composition_update_it): Mark var as initialized.
5471 (find_automatic_composition): Mark vars as initialized,
5472 with a FIXME (Bug#8290).
5473
5474 character.h: Rename locals to avoid shadowing.
5475 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
5476 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
5477 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
5478 (BUF_DEC_POS): Be more systematic about renaming local temporaries
5479 to avoid shadowing.
5480
5481 * textprop.c (property_change_between_p): Remove; unused.
5482
5483 * intervals.c (interval_start_pos): Now static.
5484

5486
5487 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
5488 Rename locals to avoid shadowing.
5489
5490 * sound.c (wav_play, au_play, Fplay_sound_internal):
5491 Fix pointer signedness.
5492 (alsa_choose_format): Remove unused local var.
5493 (wav_play): Initialize a variable to 0, to prevent undefined
5494 behavior (Bug#8278).
5495
5496 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
5497
5498 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
5499
5500 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
5501 clobbering (Bug#8298).
5502 * sysdep.c (sys_subshell): Likewise.
5503 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
5504
5505 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
5506 This should get cleaned up, so that child_setup has the
5507 same signature on all platforms.
5508
5509 * callproc.c (call_process_cleanup): Now static.
5510 (relocate_fd): Rename locals to avoid shadowing.
5511
5512 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
5513
5514 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
5515 not to be necessary, and produces flickering.
5516
5517 2011-03-20 Glenn Morris <rgm@gnu.org>
5518
5519 * config.in: Remove file.
5520
5521 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
5522
5523 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
5524 are now in src/globals.h.
5525 (syms_of_minibuf): Remove spurious & from previous change.
5526
5527 2011-03-20 Leo <sdl.web@gmail.com>
5528
5529 * minibuf.c (completing-read-function): New variable.
5530 (completing-read-default): Rename from completing-read.
5531 (completing-read): Call completing-read-function.
5532
5533 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
5534
5535 * xfaces.c (Fx_load_color_file):
5536 Read color file from absolute filename (bug#8250).
5537
5538 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
5539
5540 * makefile.w32-in: Update dependencies.
5541
5542 2011-03-17 Eli Zaretskii <eliz@gnu.org>
5543
5544 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
5545
5546 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>

5551 (sigchld_handler): Now static.
5552
5553 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
5554 That way, the code declares only the vars that it needs.
5555 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
5556 * s/cygwin.h (PTY_ITERATION): Likewise.
5557 * s/darwin.h (PTY_ITERATION): Likewise.
5558 * s/gnu-linux.h (PTY_ITERATION): Likewise.
5559
5560 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
5561 * process.c (allocate_pty): Don't declare stb unless it's needed.
5562
5563 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
5564 (CONSTANTLIM): Remove; unused.
5565 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
5566 Define only if needed.
5567
5568 * unexelf.c (unexec): Name an expression,
5569 to avoid gcc -Wbad-function-cast warning.
5570 Use a different way to cause a compilation error if anyone uses
5571 n rather than nn, a way that does not involve shadowing.
5572 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
5573
5574 * deps.mk (unexalpha.o): Remove; unused.
5575
5576 New file unexec.h, the (simple) interface for unexec (Bug#8267).
5577 * unexec.h: New file.
5578 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
5579 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
5580 Depend on unexec.h.
5581 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
5582 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
5583 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
5584 Change as necessary to match prototype in unexec.h.
5585
5586 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
5587 shadowing.
5588 (back_comment, skip_chars): Mark vars as initialized.
5589

5595
5596 * print.c (Fredirect_debugging_output): Fix pointer signedess.
5597
5598 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
5599 warning when compiling print.c.
5600
5601 * font.c (font_unparse_fcname): Abort in an "impossible" situation
5602 instead of using an uninitialized var.
5603 (font_sort_entities): Mark var as initialized.
5604
5605 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
5606

5617 (Ffillarray): Rename locals to avoid shadowing.
5618
5619 * floatfns.c (domain_error2): Define only if needed.

5621
5622 * alloc.c (mark_backtrace): Move decl from here ...
5623 * lisp.h: ... to here, so that it can be checked.
5624
5625 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
5626 (Fdefvar): Rewrite so as not to use empty "else".
5627 (lisp_indirect_variable): Name an expression,
5628 to avoid gcc -Wbad-function-cast warning.
5629 (Fdefvar): Rename locals to avoid shadowing.
5630
5631 * callint.c (quotify_arg, quotify_args): Now static.
5632 (Fcall_interactively): Rename locals to avoid shadowing.
5633 Use const pointer when appropriate.
5634
5635 * lisp.h (get_system_name, get_operating_system_release):
5636 Move decls here, to check interfaces.
5637 * process.c (get_operating_system_release): Move decl to lisp.h.
5638 * xrdb.c (get_system_name): Likewise.
5639 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
5640 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
5641 some of which prompt warnings from gcc -Wbad-function-cast.
5642 (Fformat_time_string, Fencode_time, Finsert_char):
5643 (Ftranslate_region_internal, Fformat):
5644 Rename or remove local vars to avoid shadowing.
5645 (Ftranslate_region_internal): Mark var as initialized.
5646
5647 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
5648 avoid shadowing.
5649
5650 * lisp.h (eassert): Check that the argument compiles, even if
5651 ENABLE_CHECKING is not defined.
5652
5653 * data.c (Findirect_variable): Name an expression, to avoid
5654 gcc -Wbad-function-cast warning.
5655 (default_value, arithcompare, arith_driver, arith_error): Now static.
5656 (store_symval_forwarding): Rename local to avoid shadowing.
5657 (Fmake_variable_buffer_local, Fmake_local_variable):
5658 Mark variables as initialized.
5659 (do_blv_forwarding, do_symval_forwarding): Remove; unused.
5660
5661 * alloc.c (check_cons_list): Do not define unless GC_CHECK_CONS_LIST.
5662 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
5663 Rename locals to avoid shadowing.
5664 (mark_stack): Move local variables into the #ifdef region where
5665 they're used.
5666 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
5667 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
5668 needed otherwise.
5669 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
5670 (GC_STRING_CHARS): Remove; not used.
5671 (Fmemory_limit): Cast sbrk's returned value to char *.
5672
5673 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
5674 avoids undefined behavior in theory.
5675
5676 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
5677
5678 Use functions, not macros, for up- and down-casing (Bug#8254).
5679 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5680 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
5681 to use the following functions instead of these macros.
5682 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
5683 EMACS_INT, since callers assume the returned value fits in int.
5684 (upcase1): Likewise, for UPCASE_TABLE.
5685 (uppercasep, lowercasep, upcase): New static inline functions.
5686 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
5687 the race-condition problem in the old DOWNCASE.
5688
5689 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
5690 Rename locals to avoid shadowing.
5691 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
5692 (regex_compile, re_search_2, re_match_2_internal):
5693 Remove unused local vars.
5694 (FREE_VAR): Rewrite so as not to use empty "else",
5695 which gcc can warn about.
5696 (regex_compile, re_match_2_internal): Mark locals as initialized.
5697 (RETALLOC_IF): Define only if needed.
5698 (WORDCHAR_P): Likewise. This one is never needed, but is used
5699 only in a comment talking about a compiler bug, so put inside
5700 the #if 0 of that comment.
5701 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
5702 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
5703 Remove; unused.
5704
5705 * search.c (boyer_moore): Rename locals to avoid shadowing.
5706 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
5707 (PREV_CHAR_BOUNDARY): Likewise.
5708
5709 * search.c (simple_search): Remove unused var.
5710
5711 * dired.c (compile_pattern): Move decl from here ...
5712 * lisp.h: ... to here, so that it can be checked.
5713 (struct re_registers): New forward decl.
5714
5715 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
5716
5717 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
5718 All uses changed.
5719 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
5720 Rename locals to avoid shadowing.
5721 (Fvertical_motion): Mark locals as initialized.
5722
5723 * casefiddle.c (casify_object, casify_region): Now static.
5724 (casify_region): Mark local as initialized.
5725
5726 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
5727
5728 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
5729 New macros, so that the caller can use some names other than
5730 gcpro1, gcpro2, etc.
5731 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
5732 of the new macros.
5733 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
5734 argument, for consistency with GCPRO2_VAR, etc: it is now the
5735 prefix of the variable, not the variable itself. All uses
5736 changed.
5737 * dired.c (directory_files_internal, file_name_completion):
5738 Rename locals to avoid shadowing.
5739
5740 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
5741 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
5742 dired.c's scmp function, had undefined behavior.
5743 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5744 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
5745 * buffer.h: ... to here, because these macros use current_buffer,
5746 and the new implementation with inline functions needs to have
5747 current_buffer in scope now, rather than later when the macros
5748 are used.
5749 (downcase, upcase1): New static inline functions.
5750 (DOWNCASE, UPCASE1): Reimplement using these functions.
5751 This avoids undefined behavior in expressions like
5752 DOWNCASE (x) == DOWNCASE (y), which previously suffered
5753 from race conditions in accessing the global variables
5754 case_temp1 and case_temp2.
5755 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
5756 * lisp.h (case_temp1, case_temp2): Remove their decls.
5757 * character.h (ASCII_CHAR_P): Move from here ...
5758 * lisp.h: ... to here, so that the inline functions mentioned
5759 above can use them.
5760
5761 * dired.c (directory_files_internal_unwind): Now static.
5762
5763 * fileio.c (file_name_as_directory, directory_file_name):
5764 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
5765 Now static.
5766 (file_name_as_directory): Use const pointers when appropriate.
5767 (Fexpand_file_name): Likewise. In particular, newdir might
5768 point at constant storage, so make it a const pointer.
5769 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
5770 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
5771 signedness issues.
5772 (Fset_file_times, Finsert_file_contents, auto_save_error):
5773 Rename locals to avoid shadowing.
5774
5775 * minibuf.c (choose_minibuf_frame_1): Now static.
5776 (Ftry_completion, Fall_completions): Rename or remove locals
5777 to avoid shadowing.
5778
5779 * marker.c (bytepos_to_charpos): Remove; unused.
5780
5781 * lisp.h (verify_bytepos, count_markers): New decls,
5782 so that gcc does not warn that these functions aren't declared.
5783
5784 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
5785 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
5786 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
5787 (copy_text): Remove unused local var.
5788
5789 * filelock.c (within_one_second): Now static.
5790 (lock_file_1): Rename local to avoid shadowing.
5791
5792 * buffer.c (fix_overlays_before): Mark locals as initialized.
5793 (fix_start_end_in_overlays): Likewise. This function should be
5794 simplified by using pointers-to-pointers, but that's a different
5795 matter.
5796 (switch_to_buffer_1): Now static.
5797 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
5798 (report_overlay_modification): Rename locals to avoid shadowing.
5799
5800 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
5801 Fix pointer signedness issue.
5802 (sys_subshell): Mark local as volatile if checking for lint,
5803 to suppress a gcc -Wclobbered warning that does not seem to be right.
5804 (MAXPATHLEN): Define only if needed.
