13
14 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
15
16 * composite.c (autocmp_chars): Don't reset point. That is done by

18
19 2011-08-07 Juri Linkov <juri@jurta.org>
20
21 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'

23
24 2011-08-06 Eli Zaretskii <eliz@gnu.org>
25
26 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
27 display property strides EOL and includes a newline, as in
28 longlines-mode. (Bug#9254)
29 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
30 word-wrap under bidirectional display. (Bug#9224)
31
32 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
33 is non-zero, even if the data buffer is NULL. Fixes a crash in
34 vertical-motion with longlines-mode. (Bug#9254)
35
36 2011-08-05 Eli Zaretskii <eliz@gnu.org>
37
38 * bidi.c <bidi_cache_total_alloc>: Now static.
39 (bidi_initialize): Initialize bidi_cache_total_alloc.
40
41 *xdisp.c (display_line): Release buffer allocated for shelved bidi
42 cache. (Bug#9221)
43
44 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
45 amount allocated this far in `bidi_cache_total_alloc'.
46 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
47 non-zero, only free the data buffer without restoring the cache
48 contents. All callers changed.
49
50 * dispextern.h (bidi_unshelve_cache): Update prototype.
51
52 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
53 (move_it_in_display_line, move_it_to)
54 (move_it_vertically_backward, move_it_by_lines): Replace the call
55 to xfree to an equivalent call to bidi_unshelve_cache.
56 (move_it_in_display_line_to): Fix logic of returning
57 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
58
59 2011-08-05 Eli Zaretskii <eliz@gnu.org>
60
61 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
62 came from a string character with a `cursor' property. (Bug#9229)
63
64 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
65
66 * Makefile.in (LIB_PTHREAD): New variable.
67 (LIBES): Add LIB_PTHREAD (Bug#9216).
68
69 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
70 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).

73
74 * regex.c (re_iswctype): Remove some redundant boolean
75 conversions.
76
77 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
78
79 * xterm.c (x_find_topmost_parent): New function.
80 (x_set_frame_alpha): Find topmost parent window with
81 x_find_topmost_parent and set the property there also (bug#9181).
82 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
83
84 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
85
86 * callproc.c (Fcall_process): Avoid vfork clobbering
87 the local vars buffer, coding_systems, current_dir.
88
89 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
90
91 * keymap.c (Fmake_composed_keymap): Move to subr.el.
92
93 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
94
95 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
96 so that it is not optimized away.
97
98 * xdisp.c (compute_display_string_pos): Remove unused local.
99
100 2011-08-02 Eli Zaretskii <eliz@gnu.org>
101
102 Fix slow cursor motion and scrolling in large buffers with
103 selective display, like Org Mode buffers. (Bug#9218)
104
105 * dispextern.h (struct bidi_it): New member disp_prop_p.
106
107 * xdisp.c: Remove one-slot cache of display string positions.
108 (compute_display_string_pos): Accept an additional argument
109 DISP_PROP_P; callers changed. Scan at most 5K characters forward
110 for a display string or property. If found, set DISP_PROP_P
111 non-zero.
112
113 * bidi.c (bidi_fetch_char): Accept an additional argument
114 DISP_PROP_P, and pass it to compute_display_string_pos.
115 Only handle text covered by a display string if DISP_PROP_P is returned
116 non-zero. All callers of bidi_fetch_char changed.
117
118 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
119
120 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
121
122 2010-12-03 Don March <don@ohspite.net>
123
124 * keymap.c (Fdefine_key): Fix non-prefix key error message when
125 last character M-[char] is translated to ESC [char] (bug#7541).
126
127 2011-08-02 Kenichi Handa <handa@m17n.org>
128
129 * lisp.h (uniprop_table): Extern it.
130
131 * chartab.c (uniprop_table): Make it non-static.
132
133 2011-08-01 Eli Zaretskii <eliz@gnu.org>
134
135 * xdisp.c (forward_to_next_line_start): Accept additional argument
136 BIDI_IT_PREV, and store into it the state of the bidi iterator had
137 on the newline.
138 (reseat_at_next_visible_line_start): Use the bidi iterator state
139 returned by forward_to_next_line_start to restore the state of
140 it->bidi_it after backing up to previous newline. (Bug#9212)
141
142 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
143
144 * regex.c (re_comp): Protoize.
145 (re_exec): Fix return type.
146 (regexec): Fix type of `ret'. (Bug#9203)
147
148 2011-07-29 Paul Eggert <eggert@cs.ucla.edu>
149
150 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
151 This is needed if max-image-size is a floating-point number.
152
153 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
154
155 * print.c (print_object): Print empty symbol as ##.
156
157 * lread.c (read1): Read ## as empty symbol.
158
159 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
160
161 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
162 setting frame foreground color (Bug#9175).
163 (x_set_background_color): Likewise.
164
165 * nsmenu.m (-setText): Size tooltip dimensions precisely to
166 contents (Bug#9176).
167 (EmacsTooltip -init): Remove bezels and add shadows to
168 tooltip windows.
169
170 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
171 or scroll bar (Bug#8470).
172
173 * nsfont.m (nsfont_open): Remove assignment to voffset and
174 unnecessary vars hshink, expand, hd, full_height, min_height.
175 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
176
177 * nsterm.h (nsfont_info): Remove voffset field.
178
179 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
180
181 Implement strike-through and overline on NextStep (Bug#8863).
182
183 * nsfont.m (nsfont_open): Use underline position provided by font,
184 instead of hard-coded value of 2.
185 (nsfont_draw): Call ns_draw_text_decoration instead.
186
187 * nsterm.h: Add declaration for ns_draw_text_decoration.
188
189 * nsterm.m (ns_draw_text_decoration): New function for drawing
190 underline, overline, and strike-through.
191 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
192 ns_draw_text_decoration. Change treatment of cursor drawing to
193 accomodate underlining, etc.
194
195 2011-07-28 Eli Zaretskii <eliz@gnu.org>
196
197 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
198 default.
199
200 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
201
202 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
203 Without this fix, if a signal arrives just after memory fills up,
204 'malloc' might be invoked reentrantly.
205
206 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
207 In other words, assume that every image size is allowed, on non-X
208 hosts. This assumption is probably wrong, but it lets Emacs compile.
209
210 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
211
212 * regex.c (re_iswctype): Convert return values to boolean.
213
214 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
215
216 * xdisp.c (compute_display_string_pos): Don't use cached display
217 string position if the buffer had its restriction changed.
218 (Bug#9184)
219
220 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
221
222 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
223
224 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
225
226 Integer signedness and overflow and related fixes. (Bug#9079)
227
228 * bidi.c: Integer size and overflow fixes.
229 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
230 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
231 (bidi_cache_find_level_change, bidi_cache_ensure_space)
232 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
233 (bidi_find_other_level_edge):
234 Use ptrdiff_t instead of EMACS_INT where either will do.
235 This works better on 32-bit hosts configured --with-wide-int.
236 (bidi_cache_ensure_space): Check for size-calculation overflow.
237 Use % rather than repeated addition, for better worst-case speed.
238 Don't set bidi_cache_size until after xrealloc returns, because it
239 might not return.
240 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
241 (bidi_cache_ensure_space): Also check that the bidi cache size
242 does not exceed that of the largest Lisp string or buffer. See Eli
243 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
244
245 * alloc.c (__malloc_size_t): Remove.
246 All uses replaced by size_t. See Andreas Schwab's note
247 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
248
249 * image.c: Improve checking for integer overflow.
250 (check_image_size): Assume that f is nonnull, since
251 it is always nonnull in practice. This is one less thing to
252 worry about when checking for integer overflow later.
253 (x_check_image_size): New function, which checks for integer
254 overflow issues inside X.
255 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
256 This removes the need for a memory_full check.
257 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
258 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
259 (xbm_read_bitmap_data): Change locals back to 'int', since
260 their values must fit in 'int'.
261 (xpm_load_image, png_load, tiff_load):
262 Invoke x_create_x_image_and_pixmap earlier,
263 to avoid much needless work if the image is too large.
264 (tiff_load): Treat overly large images as if
265 x_create_x_image_and_pixmap failed, not as malloc failures.
266 (gs_load): Use x_check_image_size.
267
268 * gtkutil.c: Omit integer casts.
269 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
270 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
271
272 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
273
274 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
275 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
276 would wrongly return t on a 64-bit host.
277
278 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
279 The plain *_OVERFLOW macros run afoul of GCC bug 49705
280 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
281 and therefore cause GCC to emit a bogus diagnostic in some cases.
282
283 * image.c: Integer signedness and overflow and related fixes.
284 This is not an exhaustive set of fixes, but it's time to
285 record what I've got.
286 (lookup_pixel_color, check_image_size): Remove redundant decls.
287 (check_image_size): Don't assume that arbitrary EMACS_INT values
288 fit in 'int', or that arbitrary 'double' values fit in 'int'.
289 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
290 (tiff_load, imagemagick_load_image):
291 Check for overflow in size calculations.
292 (x_create_x_image_and_pixmap): Remove unnecessary test for
293 xmalloc returning NULL; that can't happen.
294 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
295 (xpm_color_bucket): Use better integer hashing function.
296 (xpm_cache_color): Don't possibly over-allocate memory.
297 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
298 (gif_memory_source):
299 Use ptrdiff_t, not int or size_t, to record sizes.
300 (png_load): Don't assume values greater than 2**31 fit in 'int'.
301 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
302 either works, as we prefer signed integers.
303 (tiff_read_from_memory, tiff_write_from_memory):
304 Return tsize_t, not size_t, since that's what the TIFF API wants.
305 (tiff_read_from_memory): Don't fail simply because the read would
306 go past EOF; instead, return a short read.
307 (tiff_load): Omit no-longer-needed casts.
308 (Fimagemagick_types): Don't assume size fits into 'int'.
309
310 Improve hashing quality when configured --with-wide-int.
311 * fns.c (hash_string): New function, taken from sxhash_string.
312 Do not discard information about ASCII character case; this
313 discarding is no longer needed.
314 (sxhash-string): Use it. Change sig to match it. Caller changed.
315 * lisp.h: Declare it.
316 * lread.c (hash_string): Remove, since we now use fns.c's version.
317 The fns.c version returns a wider integer if --with-wide-int is
318 specified, so this should help the quality of the hashing a bit.
319
320 * emacs.c: Integer overflow minor fix.
321 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
322 Define only if GNU_LINUX.
323 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
324
325 * dispnew.c: Integer signedness and overflow fixes.
326 Remove unnecessary forward decls, that were a maintenance hassle.
327 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
328 All uses changed.
329 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
330 (scrolling_window): Use ptrdiff_t, not int, for byte count.
331 (prepare_desired_row, line_draw_cost):
332 Use int, not unsigned, where either works.
333 (save_current_matrix, restore_current_matrix):
334 Use ptrdiff_t, not size_t, where either works.
335 (init_display): Check for overflow more accurately, and without
336 relying on undefined behavior.
337
338 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
339 Remove, replacing with the new symbols in lisp.h. All uses changed.
340 * fileio.c (make_temp_name):
341 * filelock.c (lock_file_1, lock_file):
342 * xdisp.c (message_dolog):
343 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
344 Use pMd etc. instead.
345 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
346 replacing the pWIDE etc. symbols removed from editfns.c.
347
348 * keyboard.h (num_input_events): Now uintmax_t.
349 This is (very slightly) less likely to mess up due to wraparound.
350 All uses changed.
351
352 * buffer.c: Integer signedness fixes.
353 (alloc_buffer_text, enlarge_buffer_text):
354 Use ptrdiff_t rather than size_t when either will do, as we prefer
355 signed integers.
356
357 * alloc.c: Integer signedness and overflow fixes.
358 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
359 (__malloc_size_t): Default to size_t, not to int.
360 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
361 (Fgarbage_collect, mark_object_loop_halt, mark_object):
362 Prefer ptrdiff_t to size_t when either would do, as we prefer
363 signed integers.
364 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
365 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
366 Now const. Initialize with values that are in range even if char
367 is signed.
368 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
369 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
370 These functions do the right thing with sizes > 2**32.
371 (check_depth): Now ptrdiff_t, not int.
372 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
373 Adjust to new way of storing sizes. Check for size overflow bugs
374 in rest of code.
375 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
376 slightly wrong anyway, as it missed one instance of
377 XMALLOC_OVERRUN_CHECK_OVERHEAD.
378 (refill_memory_reserve): Omit needless cast to size_t.
379 (mark_object_loop_halt): Mark as externally visible.
380
381 * xselect.c: Integer signedness and overflow fixes.
382 (Fx_register_dnd_atom, x_handle_dnd_message):
383 Use ptrdiff_t, not size_t, since we prefer signed.
384 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
385 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
386 x_dnd_atoms_size and x_dnd_atoms_length.
387
388 * doprnt.c: Prefer signed to unsigned when either works.
389 * eval.c (verror):
390 * doprnt.c (doprnt):
391 * lisp.h (doprnt):
392 * xdisp.c (vmessage):
393 Use ptrdiff_t, not size_t, when using or implementing doprnt,
394 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
395 prefer signed arithmetic to avoid comparison confusion.
396 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
397 but is a bit tricky.
398
399 Assume freestanding C89 headers, string.h, stdlib.h.
400 * data.c, doprnt.c, floatfns.c, print.c:
401 Include float.h unconditionally.
402 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
403 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
404 * regex.c: Likewise for stddef.h, string.h.
405 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
406 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
407 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
408 (STDC_HEADERS): Remove obsolete defines.
409 * sysdep.c: Include limits.h unconditionally.
410
411 Assume support for memcmp, memcpy, memmove, memset.
412 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
413 * regex.c (memcmp, memcpy):
414 Remove; we assume C89 now.
415
416 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
417 (__malloc_safe_bcopy): Remove; no longer needed.
418
419 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
420 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
421 well either way, and we prefer signed to unsigned.
422
423 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
424
425 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
426 closes the connection while we're reading (bug#9182).
427
428 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
429
430 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
431 are specified (Bug#9168).
432
433 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
434
435 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
436 Found by GCC static checking and --with-wide-int on a 32-bit host.
437
438 2011-07-25 Eli Zaretskii <eliz@gnu.org>
439
440 * xdisp.c (compute_display_string_pos): Fix logic of caching
441 previous display string position. Initialize cached_prev_pos to
442 -1. Fixes slow-down at the beginning of a buffer.
443
444 2011-07-24 Eli Zaretskii <eliz@gnu.org>
445
446 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
447 for attrs[LFACE_FONTSET_INDEX].
448
449 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
450
451 * xml.c (parse_region): Remove unused local
452 that was recently introduced.
453
454 2011-07-23 Eli Zaretskii <eliz@gnu.org>
455
456 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
457 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
458
459 * xdisp.c (move_it_in_display_line_to): Record the best matching
460 position for TO_CHARPOS while scanning the line, and restore it on
461 exit if none of the characters scanned was an exact match.
462 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
463 when exact match is impossible due to invisible text, and the
464 lines are truncated.
465
466 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
467
468 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
469 for OSX >= 10.7.
470
471 2011-07-22 Eli Zaretskii <eliz@gnu.org>
472
473 Fix a significant slow-down of cursor motion with C-n, C-p,
474 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
475 auto-repeat under bidi redisplay in fontified buffers.
476 * xdisp.c (compute_stop_pos_backwards): New function.
477 (next_element_from_buffer): Call compute_stop_pos_backwards to
478 find a suitable prev_stop when we find ourselves before
479 base_level_stop.
480 (reseat): Don't look for prev_stop, as that could mean a very long
481 run.
482 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
483 <cached_disp_overlay_modiff>: Cache for last found display string
484 position.
485 (compute_display_string_pos): Return the cached position if asked
486 about the same buffer in the same area of character positions, and
487 the buffer wasn't changed since the time the display string
488 position was cached.
489
490 2011-07-22 Eli Zaretskii <eliz@gnu.org>
491
492 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
493 is an integer, which is important for empty lines. (Bug#9149)
494
495 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
496
497 * frame.c (Fmodify_frame_parameters): In tty case, update the
498 default face if necessary (Bug#4238).
499
500 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
501
502 * editfns.c (Fstring_to_char): No need to explain what a character
503 is in the docstring (Bug#6576).
504
505 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
506
507 * xml.c (parse_region): Make sure we always return a tree.
508
509 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
510
511 * xml.c (parse_region): If a document contains only comments,
512 return that, too.
513
514 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
515
516 * xml.c (make_dom): Return comments, too.
517
518 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
519
520 Port to OpenBSD.
521 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
522 and the surrounding thread.
523 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
524 rather than fgets, and retry after EINTR. Otherwise, 'emacs
525 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
526 timer goes off.
527 * s/openbsd.h (BROKEN_SIGIO): Define.
528 * unexelf.c (unexec) [__OpenBSD__]:
529 Don't update the .mdebug section of the Alpha COFF symbol table.
530
531 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
532
533 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
534 (bug#8460).
535
536 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
537
538 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
539 This fixes some race conditions on the permissions of any newly
540 created file.
541
542 * alloc.c (valid_pointer_p): Use pipe, not open.
543 This fixes some permissions issues when debugging.
544
545 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
546 If fchown fails to set both uid and gid, try to set just gid,
547 as that is sometimes allowed. Adjust the file's mode to eliminate
548 setuid or setgid bits that are inappropriate if fchown fails.
549
550 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
551
552 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
553 to compare Lisp_Objects.
554 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
555 global_gnutls_log_level, don't mistake it for a Lisp_Object.
556 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
557
558 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
559
560 * lread.c (read_integer): Unread even EOF character.
561 (read1): Likewise. Properly record start position of symbol.
562
563 * lread.c (read1): Read `#:' as empty uninterned symbol if no
564 symbol character follows.
565
566 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
567
568 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
569 This works around a problem with the previous change to Fcopy_file.
570 Recent glibc declares fchown with __attribute__((warn_unused_result)),
571 and without this change, GCC might complain about discarding
572 fchown's return value.
573
574 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
575
576 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
577
578 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
579
580 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
581
582 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
583
584 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
585 it's used from the C level.
586
587 * process.c: Use the same condition for POLL_FOR_INPUT in both
588 keyboard.c and process.c (bug#1858).
589
590 2011-07-09 Lawrence Mitchell <wence@gmx.li>
591
592 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
593 (Fgnutls_boot): Use it.
594
595 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
596
597 * doc.c (Fsubstitute_command_keys): Revert last change.
598
599 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
600
601 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
602 quotes the next character, and doesn't affect other longer
603 sequences (bug#8935).
604
605 * lread.c (syms_of_lread): Clarify that is isn't only
606 `eval-buffer' and `eval-defun' that's affected by
607 `lexical-binding' (bug#8460).
608
609 2011-07-15 Eli Zaretskii <eliz@gnu.org>
610
611 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
612 bidi redisplay when a line includes both an image and is
613 truncated.
614
615 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
616
617 Fix minor problems found by static checking.
618 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
619 (elsz): Now a signed constant, not a size_t var. We prefer signed
620 types to unsigned, to avoid integer comparison confusion. Without
621 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
622 "cannot optimize loop, the loop counter may overflow", a symptom
623 of the confusion.
624 * indent.c (Fvertical_motion): Mark locals as initialized.
625 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
626
627 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
628
629 * search.c (Fre_search_backward): Mention `case-fold-search' in
630 all the re_search_* functions (bug#8138).
631
632 * keyboard.c (Fopen_dribble_file): Document when the file is
633 closed (bug#8056).
634
635 2011-07-14 Eli Zaretskii <eliz@gnu.org>

638 bidi_cache_idx.
639
640 Support bidi reordering of display and overlay strings.
641 * xdisp.c (compute_display_string_pos)
642 (compute_display_string_end): Accept additional argument STRING.
643 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
644 (reseat_to_string): Initialize bidi_it->string.s and
645 bidi_it->string.schars.

647 NULL (avoids a crash in bidi_paragraph_init).
648 Initialize itb.string.lstring.
649 (init_iterator): Call bidi_init_it only of a valid
650 buffer position was specified. Initialize paragraph_embedding to
651 L2R.
652 (reseat_to_string): Initialize the bidi iterator.
653 (display_string): If we need to ignore text properties of
654 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
655 original value of -1 will not work with bidi.)
656 (compute_display_string_pos): First arg is now struct
657 `text_pos *'; all callers changed. Support display properties on
658 Lisp strings.
659 (compute_display_string_end): Support display properties on Lisp
660 strings.
661 (init_iterator, reseat_1, reseat_to_string): Initialize the
662 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
663 when iterating on a string not from display properties).
664 (compute_display_string_pos, compute_display_string_end):
665 Fix calculation of the object to scan. Fixes an error when using
666 arrow keys.
667 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
668 base_level_stop; instead, set base_level_stop to BEGV.
669 Fixes crashes in vertical-motion.
670 (next_element_from_buffer): Improve commentary for when
671 the iterator is before prev_stop.
672 (init_iterator): Initialize bidi_p from the default value of
673 bidi-display-reordering, not from buffer-local value. Use the
674 buffer-local value only if initializing for buffer iteration.
675 (handle_invisible_prop): Support invisible properties on strings
676 that are being bidi-reordered.
677 (set_iterator_to_next): Support bidi reordering of C strings and
678 Lisp strings.
679 (next_element_from_string): Support bidi reordering of Lisp
680 strings.
681 (handle_stop_backwards): Support Lisp strings as well.
682 (display_string): Support display of R2L glyph rows.
683 Use IT_STRING_CHARPOS when displaying from a Lisp string.
684 (init_iterator): Don't initialize it->bidi_p for strings
685 here.

693 character that is not the first one in the visual order.
694 (get_visually_first_element): New function, refactored from common
695 parts of next_element_from_buffer, next_element_from_string, and
696 next_element_from_c_string.
697 (tool_bar_lines_needed, redisplay_tool_bar)
698 (display_menu_bar): Force left-to-right direction. Add a FIXME
699 comment for making that be controlled by a user option.
700 (push_it, pop_it): Save and restore the state of the
701 bidi iterator. Save and restore the bidi_p flag.
702 (pop_it): Iterate out of display property for string iteration as
703 well.
704 (iterate_out_of_display_property): Support iteration over strings.
705 (handle_single_display_spec): Set up it->bidi_it for iteration
706 over a display string, and call bidi_init_it.
707 (handle_single_display_spec, next_overlay_string)
708 (get_overlay_strings_1, push_display_prop): Set up the bidi
709 iterator for displaying display or overlay strings.
710 (forward_to_next_line_start): Don't use the shortcut if
711 bidi-iterating.
712 (back_to_previous_visible_line_start): If handle_display_prop
713 pushed the iterator stack, restore the internal state of the bidi
714 iterator by calling bidi_pop_it same number of times.
715 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
716 and we are bidi-iterating, don't decrement the iterator position;
717 instead, set the first_elt flag in the bidi iterator, to produce
718 the same effect.
719 (reseat_1): Remove redundant setting of string_from_display_prop_p.
720 (push_display_prop): xassert that we are iterating a buffer.
721 (push_it, pop_it): Save and restore paragraph_embedding member.
722 (handle_single_display_spec, next_overlay_string)
723 (get_overlay_strings_1, reseat_1, reseat_to_string)
724 (push_display_prop): Set up the `unibyte' member of bidi_it.string
725 correctly. Don't assume unibyte strings are not bidi-reordered.
726 (compute_display_string_pos)
727 (compute_display_string_end): Fix handling the case of C string.
728 (push_it, pop_it): Save and restore from_disp_prop_p.

730 from_disp_prop_p flag.
731 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

733 popping after iteration over a string that came from a display
734 property. Fix a typo in popping stretch info. Add an assertion
735 for verifying that the iterator position is in sync with the bidi
736 iterator.
737 (handle_single_display_spec, get_overlay_strings_1)
738 (push_display_prop): Fix initialization of paragraph direction for
739 string when that of the parent object is not yet determined.
740 (reseat_1): Call bidi_init_it to resync the bidi
741 iterator with IT's position. (Bug#7616)
742 (find_row_edges): If ROW->start.pos gives position
743 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
744 (handle_stop, back_to_previous_visible_line_start, reseat_1):
745 Reset the from_disp_prop_p flag.
746 (SAVE_IT, RESTORE_IT): New macros.
747 (pos_visible_p, face_before_or_after_it_pos)

752 saving a temporary copy of the iterator and restoring it back.
753 (back_to_previous_visible_line_start, reseat_1)
754 (init_iterator): Empty the bidi cache "stack".
755 (move_it_in_display_line_to): If iterator ended up at
756 EOL, but we never saw any buffer positions smaller than
757 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
758 motion in bidi-reordered lines.
759 (move_it_in_display_line_to): Record prev_method and prev_pos
760 immediately before the call to set_iterator_to_next. Fixes cursor
761 motion in bidi-reordered lines with stretch glyphs and strings
762 displayed in margins. (Bug#8133) (Bug#8867)
763 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
764 TO_CHARPOS.
765 (pos_visible_p): Support positions in bidi-reordered lines.
766 Save and restore bidi cache.
767
768 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
769 (bidi_paragraph_info): Delete unused struct.
770 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
771 (bidi_cache_start): New variable.
772 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
773 to zero.
774 (bidi_cache_fetch_state, bidi_cache_search)
775 (bidi_cache_find_level_change, bidi_cache_iterator_state)
776 (bidi_cache_find, bidi_peek_at_next_level)

789 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
790 can now be zero (for strings); special values 0 and -1 were
791 changed to -1 and -2, respectively.
792 (bidi_char_at_pos): New function.
793 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
794 Call it instead of FETCH_MULTIBYTE_CHAR.
795 (bidi_move_to_visually_next): Abort if charpos or bytepos were not
796 initialized to valid values.
797 (bidi_init_it): Don't initialize charpos and bytepos with invalid
798 values.

835 and vector-like objects.
836
837 * dispnew.c (buffer_posn_from_coords): Save and restore the bidi
838 cache around display iteration.

880

882 The old code sometimes used this field without initializing it.
883
884 * alloc.c (gc_sweep): Don't read past end of array.

1187 Random fixes. E.g., (random) never returned negative values.
1188 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
1189 subseconds part to the entropy, as that's a bit more random.
1190 Prefer signed to unsigned, since the signedness doesn't matter and
1191 in general we prefer signed. When given a limit, use a
1192 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
1193 latter isn't right if USE_2_TAGS_FOR_INTS.
1194 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
1195 not 0..VALMASK. Don't discard "excess" bits that random () returns.

1206
1207 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
1208 This is more efficient than Ffile_directory_p and avoids a minor race.

1210 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
1211
1212 * buffer.c (Foverlay_put): Say what the return value is

1235 Qgnutls_bootprop_verify_error (which is no longer used).
1236
1237 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
1238 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
1239 Also (re)move comments that are misplaced or no longer relevant.

1340 * eval.c (struct backtrace): Simplify and port the data structure.
1341 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
1342 signed bit field, as this assumption is not portable and it makes
1343 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
1344 "char debug_on_exit : 1" as this is not portable either; instead,
1345 use the portable "unsigned int debug_on_exit : 1". Remove unused
1346 member evalargs. Remove obsolete comments about cc bombing out.

1429
1430 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
1431 bidi_at_paragraph_end, since fast_looking_at doesn't like to be

1531
1532 * lread.c: Integer overflow fixes.
1533 (read_integer): Radix is now EMACS_INT, not int,
1534 to improve quality of diagnostics for out-of-range radices.
1535 Calculate buffer size correctly for out-of-range radices.
1536 (read1): Check for integer overflow in radices, and in
1537 read-circle numbers.
1538 (read_escape): Avoid int overflow.
1539 (Fload, openp, read_buffer_size, read1)
1540 (substitute_object_recurse, read_vector, read_list, map_obarray):
1541 Use ptrdiff_t, not int, for sizes.

1562
1563 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
1564 The following patches are for when GLYPH_DEBUG && !XASSERT.
1565 * dispextern.h (trace_redisplay_p, dump_glyph_string):
1566 * dispnew.c (flush_stdout):
1567 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):

1580 (debug_method_add): Use va_list and vsprintf rather than relying
1581 on undefined behavior with wrong number of arguments.
1582 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
1583 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
1584 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
1585 since we're not interested in debugging glyphs with old libraries.
1586 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
1587 GCC 4.6.0's static checking.
1588
1589 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

1648 not unsigned long, as we prefer signed integers. All callers changed.
1649 Detect integer overflow in repeat count.
1650 (message_dolog): Don't assume print length fits in 39 bytes.
1651 (display_mode_element): Don't assume strlen fits in int.

1677 Don't assume pid_t and time_t fit in unsigned long.
1678 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.

1708 * callproc.c (getenv_internal_1, getenv_internal)
1709 (Fgetenv_internal):
1710 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
1711
1712 * lread.c (invalid_syntax): Omit length argument.
1713 All uses changed. This doesn't fix a bug, but it simplifies the
1714 code away from its former Hollerith-constant appearance, and it's
1715 one less 'int' to worry about when looking at integer-overflow issues.
1716 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
1717
1718 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
1719 This didn't break anything, but it didn't help either.
1720 It's confusing to put a bogus integer in a place where the actual
1721 value does not matter.
1722 (LIST_END_P): Remove unused macro and its bogus comment.
1723 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
1724
1725 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
1726 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
1727 implementation.
1728 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
1729 We prefer signed types, and the value cannot exceed the EMACS_INT
1730 range anyway (because otherwise the length would not be representable).
1731 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
1732 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
1733 This avoids a GCC warning when WIDE_EMACS_INT.
1734
1735 * indent.c (sane_tab_width): New function.
1736 (current_column, scan_for_column, Findent_to, position_indentation)
1737 (compute_motion): Use it. This is just for clarity.
1738 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
1739
1740 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
1741
1742 * lisp.h (lint_assume): New macro.
1743 * composite.c (composition_gstring_put_cache):
1744 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
1745
1746 * editfns.c, insdel.c:
1747 Omit unnecessary forward decls, to simplify future changes.
1748
1749 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
1750
1751 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
1752
1753 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
1754 Use much-faster test for byte-length change.
1755 Don't assume string byte-length fits in 'int'.
1756 Check that character arg fits in 'int'.
1757 (mapcar1): Declare byte as byte, for clarity.
1758
1759 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
1760
1761 * fns.c (concat): Catch string overflow earlier.
1762 Do not rely on integer wraparound.
1763
1764 * dispextern.h (struct it.overlay_strings_charpos)
1765 (struct it.selective): Now EMACS_INT, not int.
1766 * xdisp.c (forward_to_next_line_start)
1767 (back_to_previous_visible_line_start)
1768 (reseat_at_next_visible_line_start, next_element_from_buffer):
1769 Don't arbitrarily truncate the value of 'selective' to int.
1770
1771 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
1772
1773 * composite.c: Don't truncate sizes to 'int'.
1774 (composition_gstring_p, composition_reseat_it)
1775 (composition_adjust_point): Use EMACS_INT, not int.
1776 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
1777 not EMACS_UINT, for indexes.
1778
1779 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
1780
1781 * buffer.c: Include <verify.h>.
1782 (struct sortvec.priority, struct sortstr.priority):
1783 Now EMACS_INT, not int.
1784 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
1785 (struct sortstr.size, record_overlay_string)
1786 (struct sortstrlist.size, struct sortlist.used):
1787 Don't truncate size to int.
1788 (record_overlay_string): Check for size-calculation overflow.
1789 (init_buffer_once): Check at compile-time, not run-time.
1790
1791 2011-06-22 Jim Meyering <meyering@redhat.com>
1792
1793 Don't leak an XBM-image-sized buffer
1794 * image.c (xbm_load): Free the image buffer after using it.
1795
1796 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
1797
1798 Port to Sun C.
1799 * composite.c (find_automatic_composition): Omit needless 'return 0;'
1800 that Sun C diagnosed.
1801 * fns.c (secure_hash): Fix pointer signedness issue.
1802 * intervals.c (static_offset_intervals): New function.
1803 (offset_intervals): Use it.
1804
1805 2011-06-21 Leo Liu <sdl.web@gmail.com>
1806
1807 * deps.mk (fns.o):
1808 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
1809 sha512.h.
1810
1811 * fns.c (secure_hash): Rename from crypto_hash_function and change
1812 the first arg to accept symbols.
1813 (Fsecure_hash): New primitive.
1814 (syms_of_fns): New symbols.
1815
1816 2011-06-20 Deniz Dogan <deniz@dogan.se>
1817
1818 * process.c (Fset_process_buffer): Clarify return value in
1819 docstring.
1820
1821 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
1822
1823 * dispnew.c (add_window_display_history): Use BVAR.
1824
1825 * xdisp.c (debug_method_add): Use BVAR.
1826 (check_window_end, dump_glyph_matrix, dump_glyph)
1827 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
1828
1829 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
1830 Likewise.
1831
1832 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
1833 check till after the cache is created in init_frame_faces.
1834
1835 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
1836
1837 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
1838
1839 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
1840
1841 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
1842 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
1843 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
1844
1845 Improve buffer-overflow checking (Bug#8873).
1846 * fileio.c (Finsert_file_contents):
1847 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
1848 Remove the old (too-loose) buffer overflow checks.
1849 They weren't needed, since make_gap checks for buffer overflow.
1850 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
1851 The old code merely checked for Emacs fixnum overflow, and relied
1852 on undefined (wraparound) behavior. The new code avoids undefined
1853 behavior, and also checks for ptrdiff_t and/or size_t overflow.
1854
1855 * editfns.c (Finsert_char): Don't dump core with very negative counts.
1856 Tune. Don't use wider integers than needed. Don't use alloca.
1857 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
1858
1859 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
1860
1861 * insdel.c, lisp.h (buffer_overflow): New function.
1862 (insert_from_buffer_1, replace_range, replace_range_2):
1863 * insdel.c (make_gap_larger):
1864 * editfns.c (Finsert_char):
1865 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
1866
1867 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
1868
1869 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
1870
1871 Integer overflow and signedness fixes (Bug#8873).
1872
1873 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
1874 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
1875
1876 * fileio.c: Don't assume EMACS_INT fits in off_t.
1877 (emacs_lseek): New static function.
1878 (Finsert_file_contents, Fwrite_region): Use it.
1879 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
1880
1881 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
1882
1883 * fns.c: Don't overflow int when computing a list length.
1884 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
1885 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
1886 truncation on 64-bit hosts. Check for QUIT every
1887 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
1888 faster and is responsive enough.
1889 (Flength): Report an error instead of overflowing an integer.
1890 (Fsafe_length): Return a float if the value is not representable
1891 as a fixnum. This shouldn't happen except in contrived situations.
1892 (Fnthcdr, Fsort): Don't assume list length fits in int.
1893 (Fcopy_sequence): Don't assume vector length fits in int.
1894
1895 * alloc.c: Check that resized vectors' lengths fit in fixnums.
1896 (header_size, word_size): New constants.
1897 (allocate_vectorlike): Don't check size overflow here.
1898 (allocate_vector): Check it here instead, since this is the only
1899 caller of allocate_vectorlike that could cause overflow.
1900 Check that the new vector's length is representable as a fixnum.
1901
1902 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
1903 The previous code was bogus. For example, next_almost_prime (32)
1904 returned 39, which is undesirable as it is a multiple of 3; and
1905 next_almost_prime (24) returned 25, which is a multiple of 5 so
1906 why was the code bothering to check for multiples of 7?
1907
1908 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
1909
1910 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
1911
1912 Variadic C functions now count arguments with ptrdiff_t.
1913 This partly undoes my 2011-03-30 change, which replaced int with size_t.
1914 Back then I didn't know that the Emacs coding style prefers signed int.
1915 Also, in the meantime I found a few more instances where arguments
1916 were being counted with int, which may truncate counts on 64-bit
1917 machines, or EMACS_INT, which may be unnecessarily wide.
1918 * lisp.h (struct Lisp_Subr.function.aMANY)
1919 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
1920 Arg counts are now ptrdiff_t, not size_t.
1921 All variadic functions and their callers changed accordingly.
1922 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
1923 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
1924 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
1925 * callint.c (Fcall_interactively): Check arg count for overflow,
1926 to avoid potential buffer overrun. Use signed char, not 'int',
1927 for 'varies' array, so that we needn't bother to check its size
1928 calculation for overflow.
1929 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
1930 * eval.c (apply_lambda):
1931 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
1932 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
1933 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
1934
1935 * callint.c (Fcall_interactively): Don't use index var as event count.
1936
1937 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
1938 * mem-limits.h (SIZE): Remove; no longer used.
1939
1940 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
1941
1942 Remove unnecessary casts.
1943 * xterm.c (x_term_init):
1944 * xfns.c (x_set_border_pixel):
1945 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
1946 These aren't needed now that we assume ANSI C.
1947
1948 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
1949 It's more likely to cause problems (due to unsigned overflow)
1950 than to cure them.
1951
1952 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
1953
1954 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
1955
1956 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
1957
1958 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
1959
1960 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
1961
1962 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
1963
1964 GLYPH_CODE_FACE returns EMACS_INT, not int.
1965 * dispextern.h (merge_faces):
1966 * xfaces.c (merge_faces):
1967 * xdisp.c (get_next_display_element, next_element_from_display_vector):
1968 Don't assume EMACS_INT fits in int.
1969
1970 * character.h (CHAR_VALID_P): Remove unused parameter.
1971 * fontset.c, lisp.h, xdisp.c: All uses changed.
1972
1973 * editfns.c (Ftranslate_region_internal): Omit redundant test.
1974
1975 * fns.c (concat): Minor tuning based on overflow analysis.
1976 This doesn't fix any bugs. Use int to hold character, instead
1977 of constantly refetching from Emacs object. Use XFASTINT, not
1978 XINT, for value known to be a character. Don't bother comparing
1979 a single byte to 0400, as it's always less.
1980
1981 * floatfns.c (Fexpt):
1982 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
1983
1984 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
1985 for characters.
1986
1987 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
1988
1989 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
1990 Without this fix, on a 64-bit host (aset S 0 4294967386) would
1991 incorrectly succeed when S was a string, because 4294967386 was
1992 truncated before it was used.
1993
1994 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
1995 Otherwise, an out-of-range integer could cause undefined behavior
1996 on a 64-bit host.
1997
1998 * composite.c: Use int, not EMACS_INT, for characters.
1999 (fill_gstring_body, composition_compute_stop_pos): Use int, not
2000 EMACS_INT, for values that are known to be in character range.
2001 This doesn't fix any bugs but is the usual style inside Emacs and
2002 may generate better code on 32-bit machines.
2003
2004 Make sure a 64-bit char is never passed to ENCODE_CHAR.
2005 This is for reasons similar to the recent CHAR_STRING fix.
2006 * charset.c (Fencode_char): Check that character arg is actually
2007 a character. Pass an int to ENCODE_CHAR.
2008 * charset.h (ENCODE_CHAR): Verify that the character argument is no
2009 wider than 'int', as a compile-time check to prevent future regressions
2010 in this area.
2011
2012 * character.c (char_string): Remove unnecessary casts.
2013
2014 Make sure a 64-bit char is never passed to CHAR_STRING.
2015 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
2016 by silently ignoring the top 32 bits, allowing some values
2017 that were far too large to be valid characters.
2018 * character.h: Include <verify.h>.
2019 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
2020 arguments are no wider than unsigned, as a compile-time check
2021 to prevent future regressions in this area.
2022 * data.c (Faset):
2023 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
2024 (Fsubst_char_in_region):
2025 * fns.c (concat):
2026 * xdisp.c (decode_mode_spec_coding):
2027 Adjust to CHAR_STRING's new requirement.
2028 * editfns.c (Finsert_char, Fsubst_char_in_region):
2029 * fns.c (concat): Check that character args are actually
2030 characters. Without this test, these functions did the wrong
2031 thing with wildly out-of-range values on 64-bit hosts.
2032
2033 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
2034 These casts should not be needed on 32-bit hosts, either.
2035 * keyboard.c (read_char):
2036 * lread.c (Fload): Remove casts to unsigned.
2037
2038 * lisp.h (UNSIGNED_CMP): New macro.
2039 This fixes comparison bugs on 64-bit hosts.
2040 (ASCII_CHAR_P): Use it.
2041 * casefiddle.c (casify_object):
2042 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
2043 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
2044 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
2045 * dispextern.h (FACE_FROM_ID):
2046 * keyboard.c (read_char): Use UNSIGNED_CMP.
2047
2048 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
2049 not to EMACS_INT, to avoid GCC warning.
2050
2051 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
2052
2053 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
2054 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
2055 isn't needed on 32-bit machines.
2056
2057 * buffer.c (Fgenerate_new_buffer_name):
2058 Use EMACS_INT for count, not int.
2059 (advance_to_char_boundary): Return EMACS_INT, not int.
2060
2061 * data.c (Qcompiled_function): Now static.
2062
2063 * window.c (window_body_lines): Now static.
2064
2065 * image.c (gif_load): Rename local to avoid shadowing.
2066
2067 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
2068 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
2069 * alloc.c (make_save_value): Integer argument is now of type
2070 ptrdiff_t, not int.
2071 (mark_object): Use ptrdiff_t, not int.
2072 * lisp.h (pD): New macro.
2073 * print.c (print_object): Use it.
2074
2075 * alloc.c: Use EMACS_INT, not int, to count objects.
2076 (total_conses, total_markers, total_symbols, total_vector_size)
2077 (total_free_conses, total_free_markers, total_free_symbols)
2078 (total_free_floats, total_floats, total_free_intervals)
2079 (total_intervals, total_strings, total_free_strings):
2080 Now EMACS_INT, not int. All uses changed.
2081 (Fgarbage_collect): Compute overall total using a double, so that
2082 integer overflow is less likely to be a problem. Check for overflow
2083 when converting back to an integer.
2084 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
2085 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
2086 These were 'int' variables that could overflow on 64-bit hosts;
2087 they were never used, so remove them instead of repairing them.
2088 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
2089 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
2090 Previously, this ceilinged at INT_MAX, but that doesn't work on
2091 64-bit machines.
2092 (allocate_pseudovector): Don't use EMACS_INT when int would do.
2093
2094 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
2095 (allocate_vectorlike): Check for ptrdiff_t overflow.
2096 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
2097 when a (possibly-narrower) signed value would do just as well.
2098 We prefer using signed arithmetic, to avoid comparison confusion.
2099
2100 * alloc.c: Catch some string size overflows that we were missing.
2101 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
2102 for convenience in STRING_BYTES_MAX.
2103 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
2104 The definition here is exact; the one in lisp.h was approximate.
2105 (allocate_string_data): Check for string overflow. This catches
2106 some instances we weren't catching before. Also, it catches
2107 size_t overflow on (unusual) hosts where SIZE_MAX <= min
2108 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
2109 and ptrdiff_t and EMACS_INT are both 64 bits.
2110
2111 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
2112 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
2113 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
2114
2115 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
2116
2117 * alloc.c (Fmake_string): Check for out-of-range init.
2118
2119 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
2120
2121 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
2122

2560 * ftfont.c (ftfont_spec_pattern):
2561 * keymap.c (access_keymap, silly_event_symbol_error):
2562 XUINT -> XFASTINT, since the integer must be nonnegative.
2563 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
2564 since it makes no difference and we prefer signed.
2565 * keyboard.c (record_char): Use XUINT when all the neighbors do.
2566 (access_keymap): NATNUMP -> INTEGERP, since the integer must be
2567 nonnegative.

2616
2617 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
2618 Do not assume that spare memory exists; that assumption is valid
2619 only if SYSTEM_MALLOC.
2620 (LARGE_REQUEST): New macro, so that the issue of large requests
2621 is separated from the issue of spare memory.
2622
2623 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
2624

2678 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
2679 (bidi_level_of_next_char, bidi_move_to_visually_next):
2680 Support character positions inside a run of characters covered by a
2681 display string.
2682 (bidi_paragraph_init, bidi_resolve_explicit_1)
2683 (bidi_level_of_next_char): Call bidi_fetch_char and

2688 definitions.
2689 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
2690 instead of using explicit *_CHAR codes.
2691 (bidi_resolve_explicit, bidi_resolve_weak):
2692 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
2693 bidirectional text is supported only in multibyte buffers.
2694 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
2695 it to initialize the frame_window_p member of struct bidi_it.

2702 were just reseat()'ed to a new position.
2703
2704 * xdisp.c (set_cursor_from_row): Set start and stop points
2705 according to the row's direction when priming the loop that looks
2706 for the glyph on which to display cursor.
2707 (single_display_spec_intangible_p): Function deleted.
2708 (display_prop_intangible_p): Reimplement to call
2709 handle_display_spec instead of single_display_spec_intangible_p.
2710 Accept 3 additional arguments needed by handle_display_spec.
2711 This fixes incorrect cursor motion across display property with complex
2712 values: lists, `(when COND...)' forms, etc.
2713 (single_display_spec_string_p): Support property values that are
2714 lists with the argument STRING its top-level element.
2715 (display_prop_string_p): Fix the condition for processing a
2716 property that is a list to be consistent with handle_display_spec.
2717 (handle_display_spec): New function, refactored from the
2718 last portion of handle_display_prop.
2719 (compute_display_string_pos): Accept additional argument
2720 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
2721 value of a `display' property is a "replacing spec".
2722 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
2723 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
2724 the display property, but just return a value indicating whether
2725 the display property will replace the characters it covers.
2726 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
2727 frame_window_p members of struct bidi_it.
2728 (compute_display_string_pos, compute_display_string_end):

2735 display_prop_intangible_p to its new signature.
2736
2737 * dispextern.h (struct bidi_it): New member frame_window_p.
2738 (bidi_init_it): Update prototypes.
2739 (display_prop_intangible_p): Update prototype.

2751 All callers changed. (Bug#8762)
2752
2753 * gnutls.c: Use Emacs's memory allocators.
2754 Without this change, the gnutls library would invoke malloc etc.
2755 directly, which causes problems on non-SYNC_INPUT hosts, and which
2756 runs afoul of improving memory_full behavior. (Bug#8761)
2757 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
2758 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
2759 xfree instead of the default malloc, realloc, free.
2760 (Fgnutls_boot): No need to check for memory allocation failure,
2761 since xmalloc does that for us.
2762
2763 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
2764 * category.c (hash_get_category_set):

2776 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
2777 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
2778 (Fsxhash, Fgethash, Fputhash, Fmaphash):
2779 * image.c (make_image, search_image_cache, lookup_image)
2780 (xpm_put_color_table_h):
2781 * lisp.h (struct Lisp_Hash_Table):
2782 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
2783 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
2784 for hashes and hash indexes, instead of 'unsigned' and 'int'.
2785 * alloc.c (allocate_vectorlike):
2786 Check for overflow in vector size calculations.
2787 * ccl.c (ccl_driver):
2788 Check for overflow when converting EMACS_INT to int.
2789 * fns.c, image.c: Remove unnecessary static decls that would otherwise
2790 need to be updated by these changes.
2791 * fns.c (make_hash_table, maybe_resize_hash_table):
2792 Check for integer overflow with large hash tables.
2793 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
2794 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
2795 (SXHASH_REDUCE): New macro.
2796 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
2797 Use it instead of discarding useful hash info with large hash values.
2798 (sxhash_float): New function.
2799 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
2800 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
2801 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
2802 Rewrite to use FIXNUM_BITS, as this simplifies things.
2803 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
2804 Adjust signatures to match updated version of code.
2805 (consing_since_gc): Now EMACS_INT, since a single hash table can
2806 use more than INT_MAX bytes.
2807

2854
2855 Make it possible to run ./temacs.
2856
2857 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
2858 syms_of_callproc does the same thing. Remove test for
2859 "initialized", do it in the caller.

2919 * fns.c (to_uchar): Define.
2920 (crypto_hash_function): Use it to convert some newly-signed
2921 variables to unsigned, to avoid sign-extension bugs. For example,
2922 without this change, (md5 "truc") would evaluate to
2923 45723a2aff78ff4fff7fff1114760e62 rather than the expected

2934 to hold a serial number that is too large for a fixnum.
2935 (Fdbus_method_return_internal, Fdbus_method_error_internal):
2936 Check for serial numbers out of range. Decode any serial number
2937 that was so large that it became a float. (Bug#8722)
2938
2939 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
2940 (Fdbus_call_method, Fdbus_call_method_asynchronously):
2941 Use XFASTINT rather than XUINT when numbers are nonnegative.
2942 (xd_append_arg, Fdbus_method_return_internal):
2943 (Fdbus_method_error_internal): Likewise. Also, for unsigned
2944 arguments, check that Lisp number is nonnegative, rather than
2945 silently wrapping negative numbers around. (Bug#8722)

2952
2953 ccl: add integer overflow checks
2954 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
2955 (IN_INT_RANGE): New macros.
2956 (ccl_driver): Use them to check for integer overflow when
2957 decoding a CCL program. Many of the new checks are whether XINT (x)
2958 fits in int; it doesn't always, on 64-bit hosts. The new version
2959 doesn't catch all possible integer overflows, but it's an
2960 improvement. (Bug#8719)
2961
2962 * alloc.c (make_event_array): Use XINT, not XUINT.
2963 There's no need for unsigned here.
2964
2965 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
2966 This follows up to the 2011-05-06 change that substituted uintptr_t
2967 for EMACS_INT. This case wasn't caught back then.
2968
2969 Rework Fformat to avoid integer overflow issues.
2970 * editfns.c: Include <float.h> unconditionally, as it's everywhere
2971 now (part of C89). Include <verify.h>.
2972 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
2973 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
2974 (Fformat): Avoid the prepass trying to compute sizes; it was only
2975 approximate and thus did not catch overflow reliably. Instead, walk
2976 through the format just once, formatting and computing sizes as we go,
2977 checking for integer overflow at every step, and allocating a larger
2978 buffer as needed. Keep track separately whether the format is
2979 multibyte. Keep only the most-recently calculated precision, rather
2980 than them all. Record whether each argument has been converted to
2981 string. Use EMACS_INT, not int, for byte and char and arg counts.
2982 Support field widths and precisions larger than INT_MAX. Avoid
2983 sprintf's undefined behavior with conversion specifications such as %#d
2984 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
2985 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
2986 formatting out-of-range floating point numbers with int
2987 formats. (Bug#8668)
2988
2989 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
2990
2991 * data.c: Avoid integer truncation in expressions involving floats.
2992 * data.c: Include <intprops.h>.
2993 (arith_driver): When there's an integer overflow in an expression
2994 involving floating point, convert the integers to floating point
2995 so that the resulting value does not suffer from catastrophic
2996 integer truncation. For example, on a 64-bit host (* 4
2997 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
2998 Do not rely on undefined behavior after integer overflow.
2999
3000 merge count_size_as_multibyte, parse_str_to_multibyte
3001 * character.c, character.h (count_size_as_multibyte):
3002 Rename from parse_str_to_multibyte; all uses changed.
3003 Check for integer overflow.
3004 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
3005 since it's now a duplicate of the other. This is more of
3006 a character than a buffer op, so better that it's in character.c.
3007 * fns.c, print.c: Adjust to above changes.
3008
3009 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
3010
3011 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
3012
3013 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3014
3015 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3016 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
3017 (x_clipboard_manager_save): Now static.
3018 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
3019
3020 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3021 (crypto_hash_function): Now static.
3022 Fix pointer signedness problems. Avoid unnecessary initializations.
3023
3024 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
3025
3026 * termhooks.h (Vselection_alist): Make it terminal-local.
3027
3028 * terminal.c (create_terminal): Initialize it.
3029
3030 * xselect.c: Support for clipboard managers.
3031 (Vselection_alist): Move to termhooks.h as terminal-local var.
3032 (LOCAL_SELECTION): New macro.
3033 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
3034 (symbol_to_x_atom): Remove gratuitous arg.
3035 (x_handle_selection_request, lisp_data_to_selection_data)
3036 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
3037 (x_own_selection, x_get_local_selection, x_convert_selection):
3038 New arg, specifying work frame. Use terminal-local Vselection_alist.
3039 (some_frame_on_display): Delete unused function.
3040 (Fx_own_selection_internal, Fx_get_selection_internal)
3041 (Fx_disown_selection_internal, Fx_selection_owner_p)
3042 (Fx_selection_exists_p): New optional frame arg.
3043 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
3044 (x_handle_selection_clear): Don't treat other terminals with the
3045 same keyboard specially. Use the terminal-local Vselection_alist.
3046 (x_clear_frame_selections): Use Frun_hook_with_args.
3047
3048 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
3049
3050 * xterm.h: Add support for those atoms.
3051
3052 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
3053
3054 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
3055 (converted_selections, conversion_fail_tag): New global variables.
3056 (x_selection_request_lisp_error): Free the above.
3057 (x_get_local_selection): Remove unnecessary code.
3058 (x_reply_selection_request): Args changed; handle arbitrary array
3059 of converted selections stored in converted_selections.
3060 Separate the XChangeProperty and SelectionNotify steps.
3061 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
3062 (x_convert_selection): New function.
3063 (x_handle_selection_event): Simplify.
3064 (x_get_foreign_selection): Don't ignore incoming requests while
3065 waiting for an answer; this will fail when we implement
3066 SAVE_TARGETS, and seems unnecessary anyway.
3067 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
3068 (Vx_sent_selection_functions): Doc fix.
3069
3070 2011-05-26 Leo Liu <sdl.web@gmail.com>
3071
3072 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
3073
3074 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3075
3076 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
3077
3078 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
3079 for fringe update if it has periodic bitmap.
3080 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
3081 and fringe_bitmap_periodic_p.
3082
3083 * fringe.c (get_fringe_bitmap_data): New function.
3084 (draw_fringe_bitmap_1, update_window_fringes): Use it.
3085 (update_window_fringes): Record periodicity of fringe bitmap in glyph
3086 row. Mark glyph row for fringe update if periodicity changed.
3087
3088 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
3089 for fringe update unless it has periodic bitmap.
3090
3091 2011-05-25 Kenichi Handa <handa@m17n.org>
3092
3093 * xdisp.c (get_next_display_element): Set correct it->face_id for
3094 a static composition.
3095
3096 2011-05-24 Leo Liu <sdl.web@gmail.com>
3097
3098 * deps.mk (fns.o):
3099 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
3100
3101 * fns.c (crypto_hash_function, Fsha1): New function.
3102 (Fmd5): Use crypto_hash_function.
3103 (syms_of_fns): Add Ssha1.
3104
3105 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3106
3107 * gnutls.c: Remove unused macros.
3108 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
3109 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
3110 Remove macros that are defined and never used.
3111 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
3112
3113 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3114
3115 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
3116 (Fx_get_selection_internal): Minor cleanup.
3117 (Fx_own_selection_internal): Rename arguments for consistency with
3118 select.el.
3119
3120 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3121
3122 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
3123
3124 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3125
3126 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
3127
3128 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3129
3130 * dispnew.c (scrolling_window): Don't exclude the case that the
3131 last enabled row in the desired matrix touches the bottom boundary.
3132
3133 2011-05-21 Glenn Morris <rgm@gnu.org>
3134
3135 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
3136 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
3137 and add some more files.
3138
3139 2011-05-20 Eli Zaretskii <eliz@gnu.org>
3140
3141 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
3142 report_file_error introduced by the change from 2011-05-07.
3143
3144 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
3145
3146 * systime.h (Time): Define only if emacs is defined.
3147 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
3148 where the include path doesn't have X11/X.h by default. See
3149 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
3150
3151 2011-05-20 Kenichi Handa <handa@m17n.org>
3152
3153 * composite.c (find_automatic_composition): Fix previous change.
3154
3155 2011-05-20 Glenn Morris <rgm@gnu.org>
3156
3157 * lisp.mk: New file, split from Makefile.in.
3158 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
3159 (shortlisp): Remove.
3160 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
3161
3162 2011-05-19 Glenn Morris <rgm@gnu.org>
3163
3164 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
3165 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
3166 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
3167 (lisp): Set the order to that of loadup.el.
3168 (shortlisp): Make it a copy of $lisp.
3169 (SOME_MACHINE_LISP): Remove.
3170 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
3171 Use just $shortlisp, not $SOME_MACHINE_LISP too.
3172
3173 2011-05-18 Kenichi Handa <handa@m17n.org>
3174
3175 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
3176 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
3177 (find_automatic_composition): Mostly rewrite for efficiency.
3178
3179 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
3180
3181 * makefile.w32-in: Update dependencies.
3182
3183 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
3184
3185 * menu.c: Include limits.h (fixes the MS-Windows build broken by
3186 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
3187
3188 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
3189
3190 Fix some integer overflow issues, such as string length overflow.
3191
3192 * insdel.c (count_size_as_multibyte): Check for string overflow.
3193
3194 * character.c (lisp_string_width): Check for string overflow.
3195 Use EMACS_INT, not int, for string indexes and lengths; in
3196 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
3197 the resulting string length overflows an EMACS_INT; instead,
3198 report a string overflow if no precision given. When checking for
3199 precision exhaustion, use a check that cannot possibly have
3200 integer overflow. (Bug#8675)
3201 * character.h (lisp_string_width): Adjust to new signature.
3202
3203 * alloc.c (string_overflow): New function.
3204 (Fmake_string): Use it. This doesn't change behavior, but saves
3205 a few bytes and will simplify future changes.
3206 * character.c (string_escape_byte8): Likewise.
3207 * lisp.h (string_overflow): New decl.
3208
3209 Fixups, following up to the user-interface timestamp change.
3210 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
3211 for UI timestamps, instead of unsigned long.
3212 * msdos.c (mouse_get_pos): Likewise.
3213 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
3214 * w32gui.h (Time): Define by including "systime.h" rather than by
3215 declaring it ourselves. (Bug#8664)
3216
3217 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
3218 * image.c (clear_image_cache): Likewise.
3219
3220 * term.c (term_mouse_position): Don't assume time_t wraparound.
3221
3222 Be more systematic about user-interface timestamps.
3223 Before, the code sometimes used 'Time', sometimes 'unsigned long',
3224 and sometimes 'EMACS_UINT', to represent these timestamps.
3225 This change causes it to use 'Time' uniformly, as that's what X uses.
3226 This makes the code easier to follow, and makes it easier to catch
3227 integer overflow bugs such as Bug#8664.
3228 * frame.c (Fmouse_position, Fmouse_pixel_position):
3229 Use Time, not unsigned long, for user-interface timestamps.
3230 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
3231 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
3232 * keyboard.h (last_event_timestamp): Likewise.
3233 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
3234 * menu.h (xmenu_show): Likewise.
3235 * term.c (term_mouse_position): Likewise.
3236 * termhooks.h (struct input_event.timestamp): Likewise.
3237 (struct terminal.mouse_position_hook): Likewise.
3238 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
3239 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
3240 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
3241 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
3242 what it was before.
3243 * menu.h, termhooks.h: Include "systime.h", for Time.
3244
3245 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
3246 Don't assume that the difference between two unsigned long values
3247 can fit into an integer. At this point, we know button_down_time
3248 <= event->timestamp, so the difference must be nonnegative, so
3249 there's no need to cast the result if double-click-time is
3250 nonnegative, as it should be; check that it's nonnegative, just in
3251 case. This bug is triggered when events are more than 2**31 ms
3252 apart (about 25 days). (Bug#8664)
3253
3254 * xselect.c (last_event_timestamp): Remove duplicate decl.
3255 (x_own_selection): Remove needless cast to unsigned long.
3256
3257 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
3258 that always fit in int. Use a sentinel instead of a counter, to
3259 avoid a temp and to allay GCC's concerns about possible int overflow.
3260 * frame.h (struct frame): Use int for menu_bar_items_used
3261 instead of EMACS_INT, since it always fits in int.
3262
3263 * menu.c (grow_menu_items): Check for int overflow.
3264
3265 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
3266
3267 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
3268 Before, the code was not consistent. These values cannot exceed
3269 2**31 - 1 so there's no need to make them unsigned.
3270 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
3271 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
3272 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
3273 as modifiers.
3274 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
3275
3276 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
3277 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
3278 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
3279 presumably because the widths might not match.
3280
3281 * window.c (size_window): Avoid needless test at loop start.
3282
3283 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
3284
3285 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
3286
3287 2011-05-12 Drew Adams <drew.adams@oracle.com>
3288
3289 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
3290
3291 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3292
3293 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
3294 `width' to `bar_area_x' and `bar_area_width', respectively.
3295 (x_scroll_run): Take account of fringe background extension.
3296
3297 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
3298 Rename local vars `left' and `width' to `bar_area_x' and
3299 `bar_area_width', respectively.
3300 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
3301 background extension.
3302
3303 2011-05-10 Jim Meyering <meyering@redhat.com>
3304
3305 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
3306
3307 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
3308
3309 * image.c (Finit_image_library): Return t for built-in image types,
3310 like pbm and xbm. (Bug#8640)
3311
3312 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
3313
3314 * w32menu.c (set_frame_menubar): Fix submenu allocation.
3315
3316 2011-05-07 Eli Zaretskii <eliz@gnu.org>
3317
3318 * w32console.c (Fset_screen_color): Doc fix.
3319 (Fget_screen_color): New function.
3320 (syms_of_ntterm): Defsubr it.
3321
3322 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
3323 unlink the temporary file if Fcall_process didn't create it in the
3324 first place.
3325 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
3326 child process will be redirected to a file specified with `:file'.
3327 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
3328 cue to call_process_cleanup not to close that handle.
3329
3330 2011-05-07 Ben Key <bkey76@gmail.com>
3331
3332 * makefile.w32-in: The bootstrap-temacs rule now makes use of
3333 one of two shell specific rules, either bootstrap-temacs-CMD or
3334 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
3335 to the previous implementation of the bootstrap-temacs rule.
3336 The bootstrap-temacs-CMD rule is similar to the previous
3337 implementation of the bootstrap-temacs rule except that it
3338 makes use of the ESC_CFLAGS variable instead of the CFLAGS
3339 variable.
3340
3341 These changes, along with some changes to nt/configure.bat,
3342 nt/gmake.defs, and nt/nmake.defs, are required to extend my
3343 earlier fix to add support for --cflags and --ldflags options
3344 that include quotes so that it works whether make uses cmd or
3345 sh as the shell.
3346
3347 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
3348
3349 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
3350 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
3351 is a constant.
3352 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
3353 a string. Handle both cases.
3354 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
3355 (Fdbus_register_method): Use Qinvalid_function.
3356
3357 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3358
3359 * makefile.w32-in: Update dependencies.
3360 (LISP_H): Add inttypes.h and stdin.h.
3361 (PROCESS_H): Add unistd.h.
3362
3363 2011-05-06 Eli Zaretskii <eliz@gnu.org>
3364
3365 * lread.c: Include limits.h (fixes the MS-Windows build broken by
3366 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
3367
3368 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
3369
3370 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
3371
3372 * term.c (vfatal): Remove stray call to va_end.
3373 It's not needed and the C Standard doesn't allow it here anyway.
3374
3375 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
3376 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
3377
3378 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
3379 bytes.
3380
3381 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
3382
3383 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3384
3385 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
3386
3387 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
3388
3389 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
3390
3391 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
3392 * charset.c (Fdefine_charset_internal): Don't initialize
3393 charset.code_space[15]. The value was garbage, on hosts with
3394 32-bit int (Bug#8600).
3395
3396 * lread.c (read_integer): Be more consistent with string-to-number.
3397 Use string_to_number to do the actual conversion; this avoids
3398 rounding errors and fixes some other screwups. Without this fix,
3399 for example, #x1fffffffffffffff was misread as -2305843009213693952.
3400 (digit_to_number): Move earlier, for benefit of read_integer.
3401 Return -1 if the digit is out of range for the base, -2 if it is
3402 not a digit in any supported base. (Bug#8602)
3403
3404 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
3405
3406 * dispnew.c (scrolling_window): Return 1 if we scrolled,
3407 to match comment at start of function. This also removes a
3408 GCC warning about overflow in a 32+64-bit port.
3409
3410 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
3411
3412 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
3413 Reported by Stefan Monnier in
3414 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
3415 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3416 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
3417
3418 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
3419 (EMACS_UINTPTR): Likewise, with uintptr_t.
3420
3421 * lisp.h: Prefer 64-bit EMACS_INT if available.
3422 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
3423 on 32-bit hosts that have 64-bit int, so that they can access
3424 large files.
3425 However, temporarily disable this change unless the temporary
3426 symbol WIDE_EMACS_INT is defined.
3427
3428 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
3429
3430 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
3431 This removes an assumption that EMACS_INT and long are the same
3432 width as pointers. The assumption is true for Emacs porting targets
3433 now, but we want to make other targets possible.
3434 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
3435 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
3436 In the rest of the code, change types of integers that hold casted
3437 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
3438 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
3439 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
3440 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
3441 No need to cast type when ORing.
3442 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
3443 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
3444 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
3445 assume EMACS_INT is the same width as char *.
3446 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
3447 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
3448 Remove no-longer-needed casts.
3449 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
3450 (xg_tool_bar_help_callback, xg_make_tool_item):
3451 Use EMACS_INTPTR to hold an integer
3452 that will be cast to void *; this can avoid a GCC warning
3453 if EMACS_INT is not the same width as void *.
3454 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
3455 * xdisp.c (display_echo_area_1, resize_mini_window_1):
3456 (current_message_1, set_message_1):
3457 Use a local to convert to proper width without a cast.
3458 * xmenu.c (dialog_selection_callback): Likewise.
3459
3460 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
3461 Also, don't assume VALBITS / RAND_BITS is less than 5,
3462 and don't rely on undefined behavior when shifting a 1 left into
3463 the sign bit.
3464 * lisp.h (get_random): Change signature to match.
3465
3466 * lread.c (hash_string): Use size_t, not int, for hash computation.
3467 Normally we prefer signed values; but hashing is special, because
3468 it's better to use unsigned division on hash table sizes so that
3469 the remainder is nonnegative. Also, size_t is the natural width
3470 for hashing into memory. The previous code used 'int', which doesn't
3471 retain enough info to hash well into very large tables.
3472 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
3473
3474 * dbusbind.c: Don't possibly lose pointer info when converting.
3475 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3476 Use XPNTR rather than XHASH, so that the high-order bits of
3477 the pointer aren't lost when converting through void *.
3478
3479 * eval.c (Fautoload): Don't double-shift a pointer.
3480
3481 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
3482
3483 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3484
3485 * gnutls.c (DEF_GNUTLS_FN):
3486 * image.c (DEF_IMGLIB_FN): Make function pointers static.
3487
3488 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
3489
3490 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
3491 marker. (Bug#8610)
3492
3493 2011-05-05 Eli Zaretskii <eliz@gnu.org>
3494
3495 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
3496 New version that can reserve upto 2GB of heap space.
3497
3498 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
3499
3500 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
3501
3502 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
3503
3504 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
3505 `gnutls_certificate_set_x509_key_file'.
3506
3507 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
3508
3509 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
3510 Update dependencies.
3511
3512 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3513
3514 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
3515 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
3516 Remove unused parameter `fildes'.
3517 * process.c (read_process_output, send_process): Don't pass it.
3518
3519 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3520
3521 Fix previous change: the library cache is defined in w32.c.
3522 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
3523 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
3524
3525 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3526
3527 Implement dynamic loading of GnuTLS on Windows.
3528
3529 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.

3531 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
3532 Declare.

3561 Initialize and staticpro them.
3562 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
3563
3564 * process.c: Include lisp.h before w32.h, not after.
3565 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
3566 instead of gnutls_record_check_pending.

3594 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
3595 (Qgnutls_bootprop_callbacks_verify): Make static.
3596
3597 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>

3600
3601 * sysdep.c (wait_for_termination_1): Make static.
3602 (wait_for_termination, interruptible_wait_for_termination):
3603 Move after wait_for_termination_1.
3604
3605 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
3606
3607 * sysdep.c (interruptible_wait_for_termination): New function
3608 which is like wait_for_termination, but allows keyboard
3609 interruptions.
3610
3611 * callproc.c (Fcall_process): Add (:file "file") as an option for
3612 the STDOUT buffer.
3613 (Fcall_process_region): Ditto.
3614
3615 2011-04-30 Eli Zaretskii <eliz@gnu.org>
3616
3617 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
3618 rather than `XVECTOR (FOO)->size'.
3619
3620 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
3621 inttypes.h, as a gnulib replacement is used if it not available in
3622 system headers.
3623

3628 of MOST_POSITIVE_FIXNUM. (Bug#8528)
3629
3630 * coding.c (coding_alloc_by_realloc): Error out if destination
3631 will grow beyond MOST_POSITIVE_FIXNUM.
3632 (decode_coding_emacs_mule): Abort if there isn't enough place in
3633 charbuf for the composition carryover bytes. Reserve an extra
3634 space for up to 2 characters produced in a loop.
3635 (decode_coding_iso_2022): Abort if there isn't enough place in
3636 charbuf for the composition carryover bytes.
3637
3638 2011-04-21 Eli Zaretskii <eliz@gnu.org>
3639
3640 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
3641 aborting when %lld or %lll format is passed.
3642 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
3643 %llo or %llx format is passed. (Bug#8545)

3674
3675 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

3677
3678 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3679
3680 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
3681
3682 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
3683
3684 * makefile.w32-in: Update dependencies.
3685
3686 2011-04-27 Eli Zaretskii <eliz@gnu.org>
3687
3688 Improve `doprnt' and its usage. (Bug#8545)
3689 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
3690 `format_end'. Remove support for %l as a conversion specifier.
3691 Don't use xrealloc. Improve diagnostics when the %l size modifier
3692 is used. Update the commentary.
3693
3694 * eval.c (verror): Simplify calculation of size_t.
3695
3696 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
3697 messages.
3698
3699 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
3700
3701 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
3702 change.
3703
3704 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3705
3706 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
3707 This makes this file independent of the recent pseudovector change.
3708
3709 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
3710
3711 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
3712
3713 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
3714 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
3715 Remove unused local.
3716 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
3717
3718 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
3719 GCC 4.6.0 optimizes based on type-based alias analysis.
3720 For example, if b is of type struct buffer * and v of type struct
3721 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
3722 != &v->size, and therefore "v->size = 1; b->size = 2; return
3723 v->size;" must therefore return 1. This assumption is incorrect
3724 for Emacs, since it type-puns struct Lisp_Vector * with many other
3725 types. To fix this problem, this patch adds a new type struct
3726 vectorlike_header that documents the constraints on layout of vectors
3727 and pseudovectors, and helps optimizing compilers not get fooled
3728 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
3729 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
3730 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
3731 the size member.
3732 (XSETPVECTYPE): Rewrite in terms of new macro.
3733 (XSETPVECTYPESIZE): New macro, specifying both type and size.
3734 This is a bit clearer, and further avoids the possibility of
3735 undesirable aliasing.
3736 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
3737 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
3738 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
3739 since Lisp_Subr is a special case (no "next" field).
3740 (ASIZE): Now uses header.size rather than size.
3741 All previous uses of XVECTOR (foo)->size replaced to use this macro,
3742 to avoid the hassle of writing XVECTOR (foo)->header.size.
3743 (struct vectorlike_header): New type.
3744 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
3745 object, to help avoid aliasing.
3746 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
3747 (SUBRP): Likewise, since Lisp_Subr is a special case.
3748 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
3749 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
3750 (struct Lisp_Hash_Table): Combine first two members into a single
3751 struct vectorlike_header member. All uses of "size" and "next" members
3752 changed to be "header.size" and "header.next".
3753 * buffer.h (struct buffer): Likewise.
3754 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
3755 * frame.h (struct frame): Likewise.
3756 * process.h (struct Lisp_Process): Likewise.
3757 * termhooks.h (struct terminal): Likewise.
3758 * window.c (struct save_window_data, struct saved_window): Likewise.
3759 * window.h (struct window): Likewise.
3760 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
3761 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
3762 * buffer.c (init_buffer_once): Likewise.
3763 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
3764 special case.
3765 * process.c (Fformat_network_address): Use local var for size,
3766 for brevity.
3767
3768 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
3769
3770 Make the Lisp reader and string-to-float more consistent (Bug#8525)
3771 * data.c (atof): Remove decl; no longer used or needed.
3772 (digit_to_number): Move to lread.c.
3773 (Fstring_to_number): Use new string_to_number function, to be
3774 consistent with how the Lisp reader treats infinities and NaNs.
3775 Do not assume that floating-point numbers represent EMACS_INT
3776 without losing information; this is not true on most 64-bit hosts.
3777 Avoid double-rounding errors, by insisting on integers when
3778 parsing non-base-10 numbers, as the documentation specifies.
3779 * lisp.h (string_to_number): New decl, replacing ...
3780 (isfloat_string): Remove.
3781 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
3782 (read1): Do not accept +. and -. as integers; this
3783 appears to have been a coding error. Similarly, do not accept
3784 strings like +-1e0 as floating point numbers. Do not report
3785 overflow for integer overflows unless the base is not 10 which
3786 means we have no simple and reliable way to continue.
3787 Break out the floating-point parsing into a new
3788 function string_to_number, so that Fstring_to_number parses
3789 floating point numbers consistently with the Lisp reader.
3790 (digit_to_number): Move here from data.c. Make it static inline.
3791 (E_CHAR, EXP_INT): Remove, replacing with ...
3792 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
3793 (string_to_number): New function, replacing isfloat_string.
3794 This function checks for valid syntax and produces the resulting
3795 Lisp float number too. Rework it so that string-to-number
3796 no longer mishandles examples like "1.0e+". Use strtoumax,
3797 so that overflow for non-base-10 numbers is reported only when
3798 there's no portable and simple way to convert to floating point.
3799
3800 * textprop.c (set_text_properties_1): Rewrite for clarity,
3801 and to avoid GCC warning about integer overflow.
3802
3803 * intervals.h (struct interval): Use EMACS_INT for members
3804 where EMACS_UINT might cause problems. See
3805 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
3806 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
3807 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
3808 All uses changed.
3809 (offset_intervals): Tell GCC not to worry about length overflow
3810 when negating a negative length.
3811
3812 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
3813 (overrun_check_free): Likewise.
3814
3815 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
3816 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
3817 word size.
3818
3819 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3820 (gnutls_make_error): Rename local to avoid shadowing.
3821 (gnutls_emacs_global_deinit): ifdef out; not used.
3822 (Fgnutls_boot): Use const for pointer to readonly storage.
3823 Comment out unused local. Fix pointer signedness problems.
3824
3825 * lread.c (openp): Don't stuff size_t into an 'int'.
3826 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
3827 about possible signed overflow.
3828
3829 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3830 (GDK_KEY_g): Don't define if already defined.
3831 (xg_prepare_tooltip): Avoid pointer signedness problem.
3832 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
3833
3834 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
3835 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
3836
3837 * xfns.c (Fx_window_property): Simplify a bit,
3838 to make a bit faster and to avoid GCC 4.6.0 warning.
3839 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
3840
3841 * fns.c (internal_equal): Don't assume size_t fits in int.
3842
3843 * alloc.c (compact_small_strings): Tighten assertion a little.
3844
3845 Replace pEd with more-general pI, and fix some printf arg casts.
3846 * lisp.h (pI): New macro, generalizing old pEd macro to other
3847 conversion specifiers. For example, use "...%"pI"d..." rather
3848 than "...%"pEd"...".
3849 (pEd): Remove. All uses replaced with similar uses of pI.
3850 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
3851 * alloc.c (check_pure_size): Don't overflow by converting size to int.
3852 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
3853 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
3854 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
3855 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
3856 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
3857 64-bit hosts.
3858 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
3859 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
3860 * print.c (safe_debug_print, print_object): Likewise.
3861 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
3862 to int.
3863 Use pI instead of if-then-else-abort. Use %p to avoid casts,
3864 avoiding the 0 flag, which is not portable.
3865 * process.c (Fmake_network_process): Use pI to avoid cast.
3866 * region-cache.c (pp_cache): Likewise.
3867 * xdisp.c (decode_mode_spec): Likewise.
3868 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
3869 behavior on 64-bit hosts with printf arg.
3870 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
3871 (x_stop_queuing_selection_requests): Likewise.
3872 (x_get_window_property): Don't truncate byte count to an 'int'
3873 when tracing.
3874
3875 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
3876 here, since it parses constructs like leading '-' and spaces,
3877 which are not wanted; and it overflows with large numbers.
3878 Instead, simply match F[0-9]+, which is what is wanted anyway.
3879
3880 * alloc.c: Remove unportable assumptions about struct layout.
3881 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
3882 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
3883 (allocate_vectorlike, make_pure_vector): Use the new macros,
3884 plus offsetof, to remove unportable assumptions about struct layout.
3885 These assumptions hold on all porting targets that I know of, but
3886 they are not guaranteed, they're easy to remove, and removing them
3887 makes further changes easier.
3888
3889 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
3890 This doesn't fix a bug but makes the code clearer.
3891 (string_overrun_cookie): Now const. Use initializers that
3892 don't formally overflow signed char, to avoid warnings.
3893 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
3894 can cause Emacs to crash when string overrun checking is enabled.
3895 (allocate_buffer): Don't assume sizeof (struct buffer) is a
3896 multiple of sizeof (EMACS_INT); it need not be, if
3897 alignof(EMACS_INT) < sizeof (EMACS_INT).
3898 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
3899
3900 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
3901
3902 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.

3905
3906 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
3907 supposed to be handshaking. (Bug#8556)
3908 Reported by Paul Eggert <eggert@cs.ucla.edu>.
3909
3910 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
3911
3912 * lisp.h (Qdebug): List symbol.
3913 * eval.c (Qdebug): Restore global linkage.
3914 * keyboard.c (debug-on-event): New variable.
3915 (handle_user_signal): Break into debugger when debug-on-event
3916 matches the current signal symbol.
3917
3918 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
3919
3920 * alloc.c (check_sblock, check_string_bytes)
3921 (check_string_free_list): Convert to standard C.
3922
3923 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
3924

3926
3927 2011-04-25 Eli Zaretskii <eliz@gnu.org>
3928
3929 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
3930 "cast to pointer from integer of different size".
3931
3932 Improve doprnt and its use in verror. (Bug#8545)
3933 * doprnt.c (doprnt): Document the set of format control sequences
3934 supported by the function. Use SAFE_ALLOCA instead of always
3935 using `alloca'.
3936
3937 * eval.c (verror): Don't limit the buffer size at size_max-1, that
3938 is one byte too soon. Don't use xrealloc; instead xfree and
3939 xmalloc anew.
3940
3941 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
3942
3943 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
3944 callbacks stage.
3945
3946 * gnutls.c: Renamed global_initialized to
3947 gnutls_global_initialized. Added internals for the
3948 :verify-hostname-error, :verify-error, and :verify-flags
3949 parameters of `gnutls-boot' and documented those parameters in the
3950 docstring. Start callback support.
3951 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
3952 unless a fatal error occurred. Call gnutls_alert_send_appropriate
3953 on error. Return error code.
3954 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
3955 (emacs_gnutls_read): Likewise.
3956 (Fgnutls_boot): Return handshake error code.

3977
3978 * xdisp.c (handle_single_display_spec): Rename the
3979 display_replaced_before_p argument into display_replaced_p, to
3980 make it consistent with the commentary. Fix typos in the
3981 commentary.
3982
3983 * textprop.c (syms_of_textprop): Remove dead code.
3984 (copy_text_properties): Delete obsolete commentary about an
3985 interface that was deleted long ago. Fix typos in the description
3986 of arguments.

3989 to changes in oldXMenu/XMenu.h from 2011-04-16.
3990 <menu_help_message, prev_menu_help_message>: Constify.

4005 * doprnt.c (doprnt): Improve commentary.
4006
4007 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
4008
4009 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
4010 them with etags.
4011
4012 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
4013 changes in globals.h immediately force recompilation.
4014 (TAGS): Depend on $(CURDIR)/m/intel386.h and
4015 $(CURDIR)/s/ms-w32.h.
4016 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
4017
4018 * character.c (Fchar_direction): Function deleted.
4019 (syms_of_character): Don't defsubr it.
4020 <char-direction-table>: Deleted.
4021
4022 2011-04-23 Eli Zaretskii <eliz@gnu.org>
4023
4024 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
4025 * doprnt.c: Include limits.h.
4026 (SIZE_MAX): New macro.
4027 (doprnt): Return a size_t value. 2nd arg is now size_t.
4028 Many local variables are now size_t instead of int or unsigned.
4029 Improve overflow protection. Support `l' modifier for integer
4030 conversions. Support %l conversion. Don't assume an EMACS_INT
4031 argument for integer conversions and for %c.
4032
4033 * lisp.h (doprnt): Restore prototype.
4034
4035 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

4042
4043 * eval.c (internal_lisp_condition_case): Include the handler
4044 representation in the error message.

4046 when breaking from the loop.
4047
4048 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
4049
4050 * callint.c (Fcall_interactively): When displaying error message
4051 about invalid control letter, pass the character's codepoint, not
4052 a pointer to its multibyte form. Improve display of the character
4053 in octal and display also its hex code.
4054
4055 * character.c (char_string): Use %x to display the (unsigned)
4056 codepoint of an invalid character, to avoid displaying a bogus
4057 negative value.
4058
4059 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
4060 `error', not SYMBOL_NAME itself.
4061

4063 character arguments to `error'.
4064
4065 * charset.c (check_iso_charset_parameter): Fix incorrect argument
4066 to `error' in error message about FINAL_CHAR argument. Make sure
4067 FINAL_CHAR is a character, and use %c when it is passed as
4068 argument to `error'.
4069

4128
4129 * data.c (arith_error): Mark with NO_RETURN if it doesn't return.

4132 Define only if needed.
4133
4134 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
4135 by pacifying GCC about it. Maybe it's time to retire it?
4136 * xfaces.c (USG, __TIMEVAL__): Likewise.
4137
4138 * dispextern.h (struct redisplay_interface): Rename param
4139 to avoid shadowing.

4147 it.
4148
4149 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,

4256
4257 * nsfont.m: Fixed bugs in ns_get_family and
4258 ns_descriptor_to_entity that were caused by using free to
4259 deallocate memory blocks that were allocated by xmalloc (via
4260 xstrdup). This caused Emacs to crash when compiled with
4261 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
4262 --enable-checking=xmallocoverrun). xfree is now used to
4263 deallocate these memory blocks.

4604 * ccl.c (Vccl_program_table): Now static.
4605 (check_ccl_update): Remove; unused.
4606
4607 * category.c (SET_CATEGORY_SET, set_category_set): Move here.

4613
4614 * buffer.c (buffer_count): Remove unused var.
4615
4616 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
4617 so that it's not optimized away.
4618 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
4619 * dispextern.h (bidi_dump_cached_states): Remove, since it's
4620 exported only to the debugger.
4621
4622 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
4623 * atimer.h (run_all_atimers): Remove; not exported.
4624
4625 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
4626 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
4627 was inaccessible from Lisp.
4628 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
4629 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
4630
4631 alloc.c: Import and export fewer symbols, and remove unused items.
4632 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
4633 is defined.
4634 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
4635 it's not optimized away by whole-program optimization.
4636 (message_enable_multibyte, free_misc): Remove.
4637 (catchlist, handlerlist, mark_backtrace):
4638 Declare only if BYTE_MARK_STACK.

4644 (cons_free_list, last_marked_index):
4645 Now static.
4646 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
4647 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
4648 (mark_backtrace): Define only if BYTE_MARK_STACK.
4649 * xdisp.c (message_enable_multibyte): Now static.
4650
4651 Declare Lisp_Object Q* variables to be 'static' if not exported.
4652 This makes it easier for human readers (and static analyzers)
4653 to see whether these variables are used from other modules.
4654 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
4655 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
4656 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

4663 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
4664 Remove decls of unexported vars.
4665 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
4666
4667 * lisp.h (DEFINE_FUNC): Make sname 'static'.
4668
4669 Make Emacs functions such as Fatom 'static' by default.
4670 This makes it easier for human readers (and static analyzers)
4671 to see whether these functions can be called from other modules.
4672 DEFUN now defines a static function. To make the function external
4673 so that it can be used in other C modules, use the new macro DEFUE.
4674 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
4675 (Finit_image_library):
4676 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
4677 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
4678 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
4679 Remove decls, since these functions are now static.
4680 (Funintern, Fget_internal_run_time): New decls, since these functions
4681 were already external.
4682
4683 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
4684 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

4689 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
4690 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
4691 Mark functions with DEFUE instead of DEFUN,
4692 if they are used in other modules.
4693 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
4694 decls for now-static functions.
4695 * buffer.h (Fdelete_overlay): Remove decl.
4696 * callproc.c (Fgetenv_internal): Mark as internal.
4697 * composite.c (Fremove_list_of_text_properties): Remove decl.

4708 (Fremove_list_of_text_properties): Remove decls.
4709 * keyboard.c (Fthis_command_keys): Remove decl.
4710 (Fcommand_execute): New forward static decl.
4711 * keymap.c (Flookup_key): New forward static decl.
4712 (Fcopy_keymap): Now static.
4713 * keymap.h (Flookup_key): Remove decl.
4714 * process.c (Fget_process): New forward static decl.
4715 (Fprocess_datagram_address): Mark as internal.

4723

4725
4726 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
4727
4728 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
4729 change. (Bug#8496)
4730
4731 2011-04-13 Eli Zaretskii <eliz@gnu.org>
4732
4733 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
4734 when at ZV. (Bug#8487)
4735
4736 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
4737
4738 * charset.c (Fclear_charset_maps): Use xfree instead of free.
4739 (Bug#8437)
4740 * keyboard.c (parse_tool_bar_item): Likewise.
4741 * sound.c (sound_cleanup, alsa_close): Likewise.
4742 * termcap.c (tgetent): Likewise.

4744 * xsettings.c (read_and_apply_settings): Likewise.
4745
4746 * alloc.c (overrun_check_malloc, overrun_check_realloc)
4747 (overrun_check_free): Protoize.
4748
4749 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
4750
4751 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
4752 since callers should never pass a negative size.
4753 Change the signature to match that of plain 'read' and 'write'; see
4754 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
4755 * lisp.h: Update prototypes of emacs_write and emacs_read.
4756
4757 2011-04-11 Eli Zaretskii <eliz@gnu.org>
4758
4759 * xdisp.c (redisplay_window): Don't try to determine the character
4760 position of the scroll margin if the window start point w->startp
4761 is outside the buffer's accessible region. (Bug#8468)
4762
4763 2011-04-10 Eli Zaretskii <eliz@gnu.org>
4764
4765 Fix write-region and its subroutines for buffers > 2GB.
4766 * fileio.c (a_write, e_write): Modify declaration of arguments and
4767 local variables to support buffers larger than 2GB.
4768 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
4769
4770 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
4771 argument, local variables, and return value.
4772
4773 * lisp.h: Update prototypes of emacs_write and emacs_read.
4774
4775 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
4776
4777 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
4778
4779 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
4780
4781 Fix more problems found by GCC 4.6.0's static checks.
4782
4783 * xdisp.c (vmessage): Use a better test for character truncation.
4784
4785 * charset.c (load_charset_map): <, not <=, for optimization,
4786 and to avoid potential problems with integer overflow.
4787 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
4788 * casetab.c (set_identity, shuffle): Likewise.
4789 * editfns.c (Fformat): Likewise.
4790 * syntax.c (skip_chars): Likewise.
4791
4792 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
4793 This also lets GCC 4.6.0 generate slightly better loop code.
4794
4795 * callint.c (Fcall_interactively): <, not <=, for optimization.
4796 (Fcall_interactively): Count the number of arguments produced,
4797 not the number of arguments given. This is simpler and lets GCC
4798 4.6.0 generate slightly better code.
4799
4800 * ftfont.c: Distingish more carefully between FcChar8 and char.
4801 The previous code passed unsigned char * to a functions like
4802 strlen and xstrcasecmp that expect char *, which does not
4803 conform to the C standard.
4804 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
4805 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
4806 char * when the C standard requires it.
4807
4808 * keyboard.c (read_char): Remove unused var.
4809
4810 * eval.c: Port to Windows vsnprintf (Bug#8435).
4811 Include <limits.h>.
4812 (SIZE_MAX): Define if the headers do not.
4813 (verror): Do not give up if vsnprintf returns a negative count.
4814 Instead, grow the buffer. This ports to Windows vsnprintf, which
4815 does not conform to C99. Problem reported by Eli Zaretskii.
4816 Also, simplify the allocation scheme, by avoiding the need for
4817 calling realloc, and removing the ALLOCATED variable.
4818
4819 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
4820
4821 Remove invocations of doprnt, as Emacs now uses vsnprintf.
4822 But keep the doprint source code for now, as we might revamp it
4823 and use it again (Bug#8435).
4824 * lisp.h (doprnt): Remove.
4825 * Makefile.in (base_obj): Remove doprnt.o.
4826 * deps.mk (doprnt.o): Remove.
4827
4828 error: Print 32- and 64-bit integers portably (Bug#8435).
4829 Without this change, on typical 64-bit hosts error ("...%d...", N)
4830 was used to print both 32- and 64-bit integers N, which relied on
4831 undefined behavior.
4832 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
4833 New macro.
4834 * lisp.h (error, verror): Mark as printf-like functions.
4835 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
4836 Report overflow in size calculations when allocating printf buffer.
4837 Do not truncate output string at its first null byte.
4838 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
4839 Truncate the output at a character boundary, since vsnprintf does not
4840 do that.
4841 * charset.c (check_iso_charset_parameter): Convert internal
4842 character to string before calling 'error', since %c now has the
4843 printf meaning.
4844 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
4845 overflow when computing char to be passed to 'error'. Do not
4846 pass Lisp_Object to 'error'; pass the integer instead.
4847 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
4848 formatted with plain %d.
4849
4850 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
4851
4852 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
4853
4854 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
4855
4856 * xterm.c (x_catch_errors): Remove duplicate declaration.
4857
4858 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
4859
4860 * xdisp.c, lisp.h (message_nolog): Remove; unused.
4861
4862 2011-04-10 Jim Meyering <meyering@redhat.com>
4863
4864 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
4865 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
4866 return ssize_t not "int", and use size_t as the buffer length.
4867 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
4868 * gnutls.h: Update declarations.
4869 * process.c (read_process_output): Use ssize_t, to match.
4870 (send_process): Likewise.
4871
4872 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4873
4874 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
4875
4876 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4877
4878 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
4879 Use unsigned char, to match FcChar8 type definition.
4880
4881 * xterm.c (handle_one_xevent):
4882 * xmenu.c (create_and_show_popup_menu):
4883 * xselect.c (x_decline_selection_request)
4884 (x_reply_selection_request): Avoid type-punned deref of X events.
4885
4886 2011-04-09 Eli Zaretskii <eliz@gnu.org>
4887
4888 Fix some uses of `int' instead of EMACS_INT.
4889 * search.c (string_match_1, fast_string_match)
4890 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
4891 (scan_buffer, find_next_newline_no_quit)
4892 (find_before_next_newline, search_command, Freplace_match)
4893 (Fmatch_data): Make some `int' variables be EMACS_INT.
4894
4895 * xdisp.c (display_count_lines): 3rd argument and return value now
4896 EMACS_INT. All callers changed.
4897 (pint2hrstr): Last argument is now EMACS_INT.
4898
4899 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
4900 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
4901 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
4902 (decode_coding_utf_16, decode_coding_emacs_mule)
4903 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
4904 (decode_coding_ccl, decode_coding_charset)

4906 (decode_coding_iso_2022, decode_coding_emacs_mule)
4907 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
4908 <char_offset, last_offset>: Declare EMACS_INT.
4909 (encode_coding_utf_8, encode_coding_utf_16)
4910 (encode_coding_emacs_mule, encode_invocation_designation)
4911 (encode_designation_at_bol, encode_coding_iso_2022)
4912 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
4913 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
4914 Declare EMACS_INT.
4915 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
4916 (encode_invocation_designation): Last argument P_NCHARS is now
4917 EMACS_INT.
4918 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
4919 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
4920
4921 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
4922 All users changed.
4923
4924 * ccl.c (Fccl_execute_on_string): Declare some variables
4925 EMACS_INT.
4926
4927 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
4928

4933 * process.c (Fformat_network_address): Doc fix.
4934
4935 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
4936
4937 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
4938
4939 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
4940
4941 * keyboard.c (read_char): Call Lisp function help-form-show,
4942 instead of using internal_with_output_to_temp_buffer.
4943 (Qhelp_form_show): New var.
4944 (syms_of_keyboard): Use DEFSYM macro.
4945
4946 * print.c (internal_with_output_to_temp_buffer): Function deleted.
4947
4948 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
4949
4950 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
4951
4952 * process.c (Flist_processes): Remove to Lisp.
4953 (list_processes_1): Delete.
4954
4955 2011-04-06 Eli Zaretskii <eliz@gnu.org>
4956
4957 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
4958
4959 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
4960
4961 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
4962
4963 Fix more problems found by GCC 4.6.0's static checks.
4964
4965 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
4966
4967 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
4968
4969 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
4970
4971 * xdisp.c (vmessage): Mark as a printf-like function.
4972
4973 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
4974
4975 * sound.c (sound_warning): Don't crash if arg contains a printf format.
4976
4977 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
4978 printf-like functions.
4979 (tiff_load): Add casts to remove these marks before passing them
4980 to system-supplied API.
4981
4982 * eval.c (Fsignal): Remove excess argument to 'fatal'.
4983
4984 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
4985 This avoids several warnings with gcc -Wstrict-overflow.
4986 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
4987 directly, rather than having caller test rule sign. This avoids
4988 some unnecessary tests.
4989 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
4990 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This

4992
4993 * xfont.c (xfont_text_extents): Remove var that was set but not used.
4994 (xfont_open): Avoid unnecessary tests.
4995
4996 * composite.c (composition_gstring_put_cache): Use unsigned integer.

4998 * composite.h, composite.c (composition_gstring_put_cache):
4999 Use EMACS_INT, not int, for length.

5002 breaking out part of COMPOSITION_DECODE_RULE.
5003 (COMPOSITION_DECODE_RULE): Use it.
5004 * composite.c (get_composition_id): Remove unused local vars,
5005 by using the new macro.
5006
5007 * textprop.c (set_text_properties_1): Change while to do-while,
5008 since the condition is always true at first.
5009
5010 * intervals.c (graft_intervals_into_buffer): Mark var as used.
5011 (interval_deletion_adjustment): Return unsigned value.
5012 All uses changed.
5013
5014 * process.c (list_processes_1, create_pty, read_process_output):
5015 (exec_sentinel): Remove vars that were set but not used.

5026 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
5027 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
5028 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
5029
5030 * print.c (print_error_message): Avoid int overflow.
5031
5032 * font.c (font_list_entities): Redo for clarity,
5033 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
5034
5035 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
5036 (font_score): Avoid potential overflow in diff calculation.

5040
5041 * eval.c (funcall_lambda): Rename local to avoid shadowing.
5042
5043 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
5044 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
5045 can always succeed if overflow has undefined behavior.
5046
5047 * search.c (boyer_moore, wordify): Remove vars set but not used.
5048 (wordify): Omit three unnecessary tests.
5049
5050 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

5076 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
5077
5078 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
5079 that are set but not used.
5080
5081 * xfns.c (make_invisible_cursor): Don't return garbage
5082 if XCreateBitmapFromData fails (Bug#8410).
5083
5084 * xselect.c (x_get_local_selection, x_handle_property_notify):
5085 Remove vars that are set but not used.
5086
5087 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
5088 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
5089
5090 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
5091 Remove var that is set but not used.
5092 (scroll_bar_windows_size): Now size_t, not int.
5093 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
5094 Check for overflow.
5095
5096 * xfaces.c (realize_named_face): Remove vars that are set but not used.
5097 (map_tty_color) [!defined MSDOS]: Likewise.
5098
5099 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
5100
5101 * coding.c: Remove vars that are set but not used.
5102 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
5103 All callers changed.
5104 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
5105 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
5106 (decode_coding_charset): Remove vars that are set but not used.
5107
5108 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
5109 that is set but not used.
5110
5111 * print.c (print_object): Remove var that is set but not used.
5112
5113 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
5114 The gnulib version avoids calling malloc in the usual case,
5115 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
5116 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
5117 * filelock.c (current_lock_owner): Likewise.
5118 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
5119 * sysdep.c: Include allocator.h, careadlinkat.h.
5120 (emacs_no_realloc_allocator): New static constant.
5121 (emacs_readlink): New function.
5122 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
5123 ../lib/careadlinkat.h.
5124
5125 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
5126
5127 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
5128 first non-nil return value).
5129
5130 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
5131
5132 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
5133 if not defined (Bug#8403).
5134
5135 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
5136
5137 * xdisp.c (display_count_lines): Remove parameter `start',
5138 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5139 (get_char_face_and_encoding): Remove parameter `multibyte_p',

5152
5153 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
5154
5155 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
5156
5157 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
5158
5159 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
5160 later (Bug#8403).
5161
5162 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
5163
5164 Add lexical binding.
5165
5166 * window.c (Ftemp_output_buffer_show): New fun.
5167 (Fsave_window_excursion):
5168 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
5169
5170 * lread.c (lisp_file_lexically_bound_p): New function.
5171 (Fload): Bind Qlexical_binding.
5172 (readevalloop): Remove `evalfun' arg.
5173 Bind Qinternal_interpreter_environment.
5174 (Feval_buffer): Bind Qlexical_binding.
5175 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
5176 Mark as dynamic.
5177 (syms_of_lread): Declare `lexical-binding'.
5178
5179 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
5180
5181 * keyboard.c (eval_dyn): New fun.
5182 (menu_item_eval_property): Use it.
5183
5184 * image.c (parse_image_spec): Use Ffunctionp.
5185
5186 * fns.c (concat, mapcar1): Accept byte-code-functions.
5187
5188 * eval.c (Fsetq): Handle lexical vars.
5189 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
5190 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
5191 (FletX, Flet): Obey lexical binding.
5192 (Fcommandp): Handle closures.
5193 (Feval): New `lexical' arg.
5194 (eval_sub): New function extracted from Feval. Use it almost
5195 everywhere where Feval was used. Look up vars in lexical env.
5196 Handle closures.
5197 (Ffunctionp): Move from subr.el.
5198 (Ffuncall): Handle closures.
5199 (apply_lambda): Remove `eval_flags'.
5200 (funcall_lambda): Handle closures and new byte-code-functions.
5201 (Fspecial_variable_p): New function.
5202 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
5203 but without exporting it to Lisp.
5204
5205 * doc.c (Fdocumentation, store_function_docstring):
5206 * data.c (Finteractive_form): Handle closures.
5207
5208 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
5209 interactive spec.
5210
5211 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
5212 New byte-codes.
5213 (exec_byte_code): New function extracted from Fbyte_code to handle new
5214 calling convention for byte-code-functions. Add new byte-codes.
5215
5216 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
5217
5218 * alloc.c (Fmake_symbol): Init new `declared_special' field.
5219
5220 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
5221
5222 * xdisp.c (redisplay_internal): Fix prototype.
5223
5224 2011-03-31 Eli Zaretskii <eliz@gnu.org>
5225
5226 * xdisp.c (SCROLL_LIMIT): New macro.
5227 (try_scrolling): Use it when setting scroll_limit.
5228 Limit scrolling to 100 screen lines.
5229 (redisplay_window): Even when falling back on "recentering",
5230 position point in the window according to scroll-conservatively,
5231 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
5232
5233 (try_scrolling): When point is above the window, allow searching
5234 as far as scroll_max, or one screenful, to compute vertical
5235 distance from PT to the scroll margin position. This prevents
5236 try_scrolling from unnecessarily failing when
5237 scroll-conservatively is set to a value slightly larger than the
5238 window height. Clean up the case of PT below the margin at bottom
5239 of window: scroll_max can no longer be INT_MAX. When aggressive
5240 scrolling is in use, don't let point enter the opposite scroll
5241 margin as result of the scroll.
5242 (syms_of_xdisp) <scroll-conservatively>: Document the
5243 threshold of 100 lines for never-recentering scrolling.
5244
5245 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
5246
5247 * dispextern.h (move_it_by_lines):
5248 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
5249 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
5250 (message_log_check_duplicate): Remove parameters `prev_bol' and
5251 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5252 (redisplay_internal): Remove parameter `preserve_echo_area',
5253 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
5254
5255 * indent.c (Fvertical_motion):
5256 * window.c (window_scroll_pixel_based, Frecenter):
5257 Don't pass `need_y_p' to `move_it_by_lines'.
5258
5259 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
5260
5261 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
5262 steal a few bits to be more compact.
5263 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
5264 Remove unneeded casts.
5265
5266 * bytecode.c (Fbyte_code): CAR and CDR can GC.
5267
5268 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
5269
5270 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
5271 binding" message (bug#7967).
5272
5273 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
5274
5275 Fix more problems found by GCC 4.6.0's static checks.
5276
5277 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
5278 Remove unused local var.
5279
5280 * editfns.c (Fmessage_box): Remove unused local var.
5281
5282 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
5283 (note_mode_line_or_margin_highlight, note_mouse_highlight):
5284 Omit unused local vars.
5285 * window.c (shrink_windows): Omit unused local var.
5286 * menu.c (digest_single_submenu): Omit unused local var.
5287 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
5288 Omit unused local var.
5289
5290 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
5291 Don't assume string length fits in int.
5292 (keyremap_step, read_key_sequence): Use size_t for sizes.
5293 (read_key_sequence): Don't check last_real_key_start redundantly.
5294
5295 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
5296 instead of alloca (Bug#8344).

5299 (Fbacktrace_frame): Don't assume nframes fits in int.
5300
5301 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
5302
5303 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
5304 concerns.
5305
5306 * term.c (produce_glyphless_glyph): Remove unnecessary test.
5307
5308 * cm.c (calccost): Turn while-do into do-while, for clarity.
5309
5310 * keyboard.c (syms_of_keyboard): Use the same style as later
5311 in this function when indexing through an array. This also
5312 works around GCC bug 48267.
5313
5314 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
5315
5316 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
5317
5318 * chartab.c (sub_char_table_ref_and_range): Redo for slight
5319 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
5320
5321 * keyboard.c, keyboard.h (num_input_events): Now size_t.
5322 This avoids undefined behavior on integer overflow, and is a bit
5323 more convenient anyway since it is compared to a size_t variable.
5324
5325 Variadic C functions now count arguments with size_t, not int.
5326 This avoids an unnecessary limitation on 64-bit machines, which
5327 caused (substring ...) to crash on large vectors (Bug#8344).
5328 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
5329 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
5330 All variadic functions and their callers changed accordingly.

5335 (internal_condition_case_n, run_hook_with_args, apply_lambda)
5336 (funcall_lambda, mark_backtrace): Likewise.
5337 * fns.c (concat): Likewise.
5338 * frame.c (x_set_frame_parameters): Likewise.
5339 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
5340 0 if not found, not -1. All callers changed.
5341
5342 * alloc.c (garbage_collect): Don't assume stack size fits in int.
5343 (stack_copy_size): Now size_t, not int.
5344 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

5353 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
5354 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

5362 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5363
5364 * keyboard.c (safe_run_hook_funcall): New function.
5365 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
5366 don't set the hook to nil, but remove the offending function instead.
5367 (Qcommand_hook_internal): Remove, unused.
5368 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
5369 Vcommand_hook_internal.
5370
5371 * eval.c (enum run_hooks_condition): Remove.
5372 (funcall_nil, funcall_not): New functions.
5373 (run_hook_with_args): Call each function through a `funcall' argument.
5374 Remove `cond' argument, now redundant.

5376 (Frun_hook_with_args_until_failure): Adjust accordingly.
5377 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
5378

5382
5383 * print.c (strout): Remove parameter `multibyte', unused since
5384 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
5385

5387 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
5388 All callers changed.
5389
5390 * w32.c (_wsa_errlist): Use braces for struct initializers.

5556
5557 Fix more problems found by GCC 4.5.2's static checks.
5558
5559 * coding.c (encode_coding_raw_text): Avoid unnecessary test
5560 the first time through the loop, since we know p0 < p1 then.
5561 This also avoids a gcc -Wstrict-overflow warning.
5562
5563 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
5564 leading to a memory leak, possible in functions like
5565 load_charset_map_from_file that can allocate an unbounded number
5566 of objects (Bug#8318).
5567
5568 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
5569 that could (at least in theory) be that large.
5570
5571 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
5572 This is less likely to overflow, and avoids undefined behavior if
5573 overflow does occur. All callers changed. Use strtoul to scan
5574 for the unsigned long integer.
5575 (pint2hrstr): Simplify and tune code slightly.
5576 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

5590
5591 * process.c (Fmake_network_process): Use socklen_t, not int,
5592 where POSIX says socklen_t is required in portable programs.
5593 This fixes a porting bug on hosts like 64-bit HP-UX, where
5594 socklen_t is wider than int (Bug#8277).
5595 (Fmake_network_process, server_accept_connection):
5596 (wait_reading_process_output, read_process_output):
5597 Likewise.
5598

5607 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
5608
5609 Make tparam.h and terminfo.c consistent.
5610 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
5611 Include tparam.h instead, since it declares them.
5612 * cm.h (PC): Remove extern decl; tparam.h now does this.
5613 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
5614 * terminfo.c: Include tparam.h, to check interfaces.
5615 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
5616 (tparam): Adjust signature to match interface in tparam.h;
5617 this removes some undefined behavior. Check that outstring and len
5618 are zero, which they always are with Emacs.
5619 * tparam.h (PC, BC, UP): New extern decls.
5620
5621 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

5642 with a FIXME (Bug#8290).
5643

5647 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
5648 (BUF_DEC_POS): Be more systematic about renaming local temporaries
5649 to avoid shadowing.

5658 Rename locals to avoid shadowing.
5659
5660 * sound.c (wav_play, au_play, Fplay_sound_internal):
5661 Fix pointer signedness.
5662 (alsa_choose_format): Remove unused local var.
5663 (wav_play): Initialize a variable to 0, to prevent undefined
5664 behavior (Bug#8278).
5665
5666 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
5667
5668 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
5669
5670 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
5671 clobbering (Bug#8298).
5672 * sysdep.c (sys_subshell): Likewise.
5673 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
5674
5675 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
5676 This should get cleaned up, so that child_setup has the
5677 same signature on all platforms.
5678
5679 * callproc.c (call_process_cleanup): Now static.
5680 (relocate_fd): Rename locals to avoid shadowing.

5682 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
5683
5684 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
5685 not to be necessary, and produces flickering.

5829 (do_blv_forwarding, do_symval_forwarding): Remove; unused.
5830
5831 * alloc.c (check_cons_list): Do not define unless GC_CHECK_CONS_LIST.
5832 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
5833 Rename locals to avoid shadowing.
5834 (mark_stack): Move local variables into the #ifdef region where
5835 they're used.
5836 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
5837 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
5838 needed otherwise.
5839 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
5840 (GC_STRING_CHARS): Remove; not used.
5841 (Fmemory_limit): Cast sbrk's returned value to char *.
5842
5843 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
5844 avoids undefined behavior in theory.
5845
5846 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
5847
5848 Use functions, not macros, for up- and down-casing (Bug#8254).
5849 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5850 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
5851 to use the following functions instead of these macros.
5852 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
5853 EMACS_INT, since callers assume the returned value fits in int.
5854 (upcase1): Likewise, for UPCASE_TABLE.
5855 (uppercasep, lowercasep, upcase): New static inline functions.
5856 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
5857 the race-condition problem in the old DOWNCASE.
5858
5859 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
5860 Rename locals to avoid shadowing.
5861 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
5862 (regex_compile, re_search_2, re_match_2_internal):
5863 Remove unused local vars.
5864 (FREE_VAR): Rewrite so as not to use empty "else",
5865 which gcc can warn about.
5866 (regex_compile, re_match_2_internal): Mark locals as initialized.
5867 (RETALLOC_IF): Define only if needed.
5868 (WORDCHAR_P): Likewise. This one is never needed, but is used
5869 only in a comment talking about a compiler bug, so put inside
5870 the #if 0 of that comment.
5871 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
5872 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
5873 Remove; unused.
5874
5875 * search.c (boyer_moore): Rename locals to avoid shadowing.
5876 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
5877 (PREV_CHAR_BOUNDARY): Likewise.

5880
5881 * dired.c (compile_pattern): Move decl from here ...
5882 * lisp.h: ... to here, so that it can be checked.
5883 (struct re_registers): New forward decl.
5884
5885 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
5886
5887 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
5888 All uses changed.
5889 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
5890 Rename locals to avoid shadowing.
5891 (Fvertical_motion): Mark locals as initialized.
5892
5893 * casefiddle.c (casify_object, casify_region): Now static.
5894 (casify_region): Mark local as initialized.
5895
5896 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
5897
5898 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
5899 New macros, so that the caller can use some names other than
5900 gcpro1, gcpro2, etc.
5901 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
5902 of the new macros.
5903 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
5904 argument, for consistency with GCPRO2_VAR, etc: it is now the
5905 prefix of the variable, not the variable itself. All uses
5906 changed.
5907 * dired.c (directory_files_internal, file_name_completion):
5908 Rename locals to avoid shadowing.
5909
5910 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
5911 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
5912 dired.c's scmp function, had undefined behavior.
5913 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5914 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
5915 * buffer.h: ... to here, because these macros use current_buffer,
5916 and the new implementation with inline functions needs to have
5917 current_buffer in scope now, rather than later when the macros
5918 are used.
5919 (downcase, upcase1): New static inline functions.
5920 (DOWNCASE, UPCASE1): Reimplement using these functions.
5921 This avoids undefined behavior in expressions like
5922 DOWNCASE (x) == DOWNCASE (y), which previously suffered
5923 from race conditions in accessing the global variables
5924 case_temp1 and case_temp2.
5925 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
5926 * lisp.h (case_temp1, case_temp2): Remove their decls.
5927 * character.h (ASCII_CHAR_P): Move from here ...
5928 * lisp.h: ... to here, so that the inline functions mentioned
5929 above can use them.
5930
5931 * dired.c (directory_files_internal_unwind): Now static.
5932
5933 * fileio.c (file_name_as_directory, directory_file_name):
5934 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
5935 Now static.
5936 (file_name_as_directory): Use const pointers when appropriate.
5937 (Fexpand_file_name): Likewise. In particular, newdir might
5938 point at constant storage, so make it a const pointer.
5939 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
5940 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
5941 signedness issues.
5942 (Fset_file_times, Finsert_file_contents, auto_save_error):
5943 Rename locals to avoid shadowing.
5944
5945 * minibuf.c (choose_minibuf_frame_1): Now static.
5946 (Ftry_completion, Fall_completions): Rename or remove locals
5947 to avoid shadowing.
5948
5949 * marker.c (bytepos_to_charpos): Remove; unused.
5950
5951 * lisp.h (verify_bytepos, count_markers): New decls,
5952 so that gcc does not warn that these functions aren't declared.
5953
5954 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
5955 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
5956 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
5957 (copy_text): Remove unused local var.
5958
5959 * filelock.c (within_one_second): Now static.
5960 (lock_file_1): Rename local to avoid shadowing.
5961
5962 * buffer.c (fix_overlays_before): Mark locals as initialized.
5963 (fix_start_end_in_overlays): Likewise. This function should be
5964 simplified by using pointers-to-pointers, but that's a different
5965 matter.
5966 (switch_to_buffer_1): Now static.
5967 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
5968 (report_overlay_modification): Rename locals to avoid shadowing.
5969
5970 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
5971 Fix pointer signedness issue.
5972 (sys_subshell): Mark local as volatile if checking for lint,
5973 to suppress a gcc -Wclobbered warning that does not seem to be right.
5974 (MAXPATHLEN): Define only if needed.
5975
5976 * process.c (serial_open, serial_configure): Move decls from here ...
5977 * systty.h: ... to here, so that they can be checked.
5978
5979 * fns.c (get_random, seed_random): Move extern decls from here ...
5980 * lisp.h: ... to here, so that they can be checked.
5981
5982 * sysdep.c (reset_io): Now static.
5983 (wait_for_termination_signal): Remove; unused.
5984
5985 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
5986 (copy_keymap_item, append_key, push_text_char_description):
5987 Now static.
5988 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
5989 (DENSE_TABLE_SIZE): Remove; unused.
5990 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
5991 (describe_map_tree):
5992 Rename locals to avoid shadowing.
5993
5994 * keyboard.c: Declare functions static if they are not used elsewhere.
5995 (echo_char, echo_dash, cmd_error, top_level_2):
5996 (poll_for_input, handle_async_input): Now static.
5997 (read_char, kbd_buffer_get_event, make_lispy_position):
5998 (make_lispy_event, make_lispy_movement, apply_modifiers):
5999 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):

6008
6009 * lisp.h (force_auto_save_soon): New decl.
6010
6011 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
6012 (DEFINE_DUMMY_FUNCTION): New macro.
6013 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
6014 Use it.
6015 (main): Add casts to avoid warnings
6016 if GCC considers string literals to be constants.
6017
6018 * lisp.h (fatal_error_signal): Add decl, since it's exported.
6019
6020 * dbusbind.c: Pointer signedness fixes.
6021 (xd_signature, xd_append_arg, xd_initialize):
6022 (Fdbus_call_method, Fdbus_call_method_asynchronously):

6141 For example, without this patch (encode-time 0 0 0 1 1
6142 1152921504606846976) returns the obviously-bogus value (-948597
6143 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
6144 reports time overflow. See
