33 (xg_store_widget_in_map, xg_remove_widget_from_map)
34 (xg_get_widget_from_map, xg_get_scroll_id_for_window)

44 * fringe.c (Fdefine_fringe_bitmap): Don't update size until alloc works.
46 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
47 This is for the members text_lines, text_cols, total_lines, total_cols,
48 where the system imposes an 'int' limit.
50 * frame.c: Integer overflow fixes.
51 (set_menu_bar_lines, x_set_frame_parameters, x_set_scroll_bar_width)

108 * buffer.c: Memory overflow fixes.
109 (overlays_at, overlays_in, record_overlay_string, overlay_strings):
110 Don't update size of array until after memory allocation succeeds,
111 because xmalloc/xrealloc may not return.
113 * bidi.c: Integer overflow fix.
114 (bidi_shelve_header_size): New constant.
115 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.

127 Use ptrdiff_t, not int, for composition IDs.
128 * composite.c (get_composition_id): Check for integer overflow.
129 * composite.h: Adjust prototypes to match the above changes.
131 Use ptrdiff_t for hash table indexes.

133 * ccl.c (ccl_driver):
134 * charset.h (struct charset.hash_index, CHECK_CHARSET_GET_ID):
135 * coding.c (coding_system_charset_list, detect_coding_system):
136 * coding.h (struct coding_system.id):
137 * composite.c (get_composition_id, gstring_lookup_cache):
138 * fns.c (hash_lookup, hash_put, Fgethash, Fputhash):
139 * image.c (xpm_get_color_table_h):
140 * lisp.h (hash_lookup, hash_put):
141 * minibuf.c (Ftest_completion):
142 Use ptrdiff_t for hash table indexes, not int (which is too
143 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
144 32-bit --with-wide-int hosts).
146 * charset.c (Fdefine_charset_internal): Check for integer overflow.
147 Add a FIXME comment about memory leaks.
148 (syms_of_charset): Don't assume xmalloc returns.
150 Don't assume that stated character widths fit in int.
151 * character.c (Fchar_width, c_string_width, lisp_string_width):
152 * character.h (CHAR_WIDTH):
153 * indent.c (MULTIBYTE_BYTES_WIDTH):
154 Use sanitize_char_width to avoid undefined and/or bad behavior
155 with outlandish widths.
156 * character.h (sanitize_tab_width): Renamed from sanitize_width,
157 now that we have two such functions. All uses changed.
158 (sanitize_char_width): New inline function.
160 Don't assume that tab-width fits in int.
161 * character.h (sanitize_width): New inline function.
162 (SANE_TAB_WIDTH): New macro.
163 (ASCII_CHAR_WIDTH): Use it.
164 * indent.c (sane_tab_width): Remove. All uses replaced by
165 SANE_TAB_WIDTH (current_buffer).

168 * fileio.c: Integer overflow issues with file modes.
169 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
171 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
172 Remove unreachable code.
173 (read_hex, load_charset_map_from_file): Check for integer overflow.
175 * xterm.c: don't go over XClientMessageEvent limit
176 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
177 (x_send_scroll_bar_event): Likewise. Check that the size does not
178 exceed limits imposed by XClientMessageEvent, as well as the usual
179 ptrdiff_t and size_t limits.
181 * keyboard.c: Overflow, signedness and related fixes.
182 (make_lispy_movement): Use same integer type in forward decl
183 that is used in the definition.
184 (read_key_sequence, keyremap_step):
185 Change bufsize argument back to int, undoing my 2011-03-30 change.
186 We prefer signed types, and int is wide enough here.
187 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
188 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
189 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
190 length, not size_t. Use ptrdiff_t for index, not int.
191 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
192 possibility of integer overflow.
194 Overflow, signedness and related fixes for images.
196 * dispextern.h (struct it.stack[0].u.image.image_id)
197 (struct_it.image_id, struct image.id, struct image_cache.size)
198 (struct image_cache.used, struct image_cache.ref_count):
199 * gtkutil.c (update_frame_tool_bar):
200 * image.c (x_reference_bitmap, Fimage_size, Fimage_mask_p)
201 (Fimage_metadata, free_image_cache, clear_image_cache, lookup_image)
202 (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
203 * nsmenu.m (update_frame_tool_bar):
204 * xdisp.c (calc_pixel_width_or_height):
205 * xfns.c (image_cache_refcount):
206 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
207 on typical 64-bit hosts.
209 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
210 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
211 Omit unnecessary casts to int.
212 (parse_image_spec): Check that integers fall into 'int' range
213 when the callers expect that.
214 (image_ascent): Redo ascent calculation to avoid int overflow.
215 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
216 (lookup_image): Remove unnecessary tests.
217 (xbm_image_p): Locals are now of int, not EMACS_INT,
218 since parse_image_check makes sure they fit into int.
219 (png_load, gif_load, svg_load_image):
220 Prefer int to unsigned where either will do.
221 (tiff_handler): New function, combining the cores of the
222 old tiff_error_handler and tiff_warning_handler. This
223 function is rewritten to use vsnprintf and thereby avoid
224 stack buffer overflows. It uses only the features of vsnprintf
225 that are common to both POSIX and native Microsoft.
226 (tiff_error_handler, tiff_warning_handler): Use it.
227 (tiff_load, gif_load, imagemagick_load_image):
228 Don't assume :index value fits in 'int'.
229 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
230 (imagemagick_load_image): Check that crop parameters fit into
231 the integer types that MagickCropImage accepts. Don't assume
232 Vimagemagick_render_type has a nonnegative value. Don't assume
233 size_t fits in 'long'.
234 (gs_load): Use printmax_t to print the widest integers possible.
235 Check for integer overflow when computing image height and width.
237 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
239 Integer signedness and overflow and related fixes. (Bug#9079)
241 * bidi.c: Integer size and overflow fixes.
242 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
243 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
244 (bidi_cache_find_level_change, bidi_cache_ensure_space)
245 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
246 (bidi_find_other_level_edge):
247 Use ptrdiff_t instead of EMACS_INT where either will do.
248 This works better on 32-bit hosts configured --with-wide-int.
249 (bidi_cache_ensure_space): Check for size-calculation overflow.
250 Use % rather than repeated addition, for better worst-case speed.
251 Don't set bidi_cache_size until after xrealloc returns, because it
253 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
254 (bidi_cache_ensure_space): Also check that the bidi cache size
255 does not exceed that of the largest Lisp string or buffer. See Eli
256 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
258 * alloc.c (__malloc_size_t): Remove.
259 All uses replaced by size_t. See Andreas Schwab's note
260 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
262 * image.c: Improve checking for integer overflow.
263 (check_image_size): Assume that f is nonnull, since
264 it is always nonnull in practice. This is one less thing to
265 worry about when checking for integer overflow later.
266 (x_check_image_size): New function, which checks for integer
267 overflow issues inside X.
268 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
269 This removes the need for a memory_full check.
270 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
271 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
272 (xbm_read_bitmap_data): Change locals back to 'int', since
273 their values must fit in 'int'.
274 (xpm_load_image, png_load, tiff_load):
275 Invoke x_create_x_image_and_pixmap earlier,
276 to avoid much needless work if the image is too large.
277 (tiff_load): Treat overly large images as if
278 x_create_x_image_and_pixmap failed, not as malloc failures.
279 (gs_load): Use x_check_image_size.
281 * gtkutil.c: Omit integer casts.
282 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
283 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
285 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
287 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
288 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
289 would wrongly return t on a 64-bit host.
291 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
292 The plain *_OVERFLOW macros run afoul of GCC bug 49705
293 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
294 and therefore cause GCC to emit a bogus diagnostic in some cases.
296 * image.c: Integer signedness and overflow and related fixes.
297 This is not an exhaustive set of fixes, but it's time to
298 record what I've got.
299 (lookup_pixel_color, check_image_size): Remove redundant decls.
300 (check_image_size): Don't assume that arbitrary EMACS_INT values
301 fit in 'int', or that arbitrary 'double' values fit in 'int'.
302 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
303 (tiff_load, imagemagick_load_image):
304 Check for overflow in size calculations.
305 (x_create_x_image_and_pixmap): Remove unnecessary test for
306 xmalloc returning NULL; that can't happen.
307 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
308 (xpm_color_bucket): Use better integer hashing function.
309 (xpm_cache_color): Don't possibly over-allocate memory.
310 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
312 Use ptrdiff_t, not int or size_t, to record sizes.
313 (png_load): Don't assume values greater than 2**31 fit in 'int'.
314 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
315 either works, as we prefer signed integers.
316 (tiff_read_from_memory, tiff_write_from_memory):
317 Return tsize_t, not size_t, since that's what the TIFF API wants.
318 (tiff_read_from_memory): Don't fail simply because the read would
319 go past EOF; instead, return a short read.
320 (tiff_load): Omit no-longer-needed casts.
321 (Fimagemagick_types): Don't assume size fits into 'int'.
323 Improve hashing quality when configured --with-wide-int.
324 * fns.c (hash_string): New function, taken from sxhash_string.
325 Do not discard information about ASCII character case; this
326 discarding is no longer needed.
327 (sxhash-string): Use it. Change sig to match it. Caller changed.
328 * lisp.h: Declare it.
329 * lread.c (hash_string): Remove, since we now use fns.c's version.
330 The fns.c version returns a wider integer if --with-wide-int is
331 specified, so this should help the quality of the hashing a bit.
333 * emacs.c: Integer overflow minor fix.
334 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
335 Define only if GNU_LINUX.
336 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
338 * dispnew.c: Integer signedness and overflow fixes.
339 Remove unnecessary forward decls, that were a maintenance hassle.
340 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
342 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
343 (scrolling_window): Use ptrdiff_t, not int, for byte count.
344 (prepare_desired_row, line_draw_cost):
345 Use int, not unsigned, where either works.
346 (save_current_matrix, restore_current_matrix):
347 Use ptrdiff_t, not size_t, where either works.
348 (init_display): Check for overflow more accurately, and without
349 relying on undefined behavior.
351 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
352 Remove, replacing with the new symbols in lisp.h. All uses changed.
353 * fileio.c (make_temp_name):
354 * filelock.c (lock_file_1, lock_file):
355 * xdisp.c (message_dolog):
356 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
357 Use pMd etc. instead.
358 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
359 replacing the pWIDE etc. symbols removed from editfns.c.
361 * keyboard.h (num_input_events): Now uintmax_t.
362 This is (very slightly) less likely to mess up due to wraparound.
365 * buffer.c: Integer signedness fixes.
366 (alloc_buffer_text, enlarge_buffer_text):
367 Use ptrdiff_t rather than size_t when either will do, as we prefer
370 * alloc.c: Integer signedness and overflow fixes.
371 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
372 (__malloc_size_t): Default to size_t, not to int.
373 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
374 (Fgarbage_collect, mark_object_loop_halt, mark_object):
375 Prefer ptrdiff_t to size_t when either would do, as we prefer
377 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
378 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
379 Now const. Initialize with values that are in range even if char
381 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
382 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
383 These functions do the right thing with sizes > 2**32.
384 (check_depth): Now ptrdiff_t, not int.
385 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
386 Adjust to new way of storing sizes. Check for size overflow bugs
388 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
389 slightly wrong anyway, as it missed one instance of
390 XMALLOC_OVERRUN_CHECK_OVERHEAD.
391 (refill_memory_reserve): Omit needless cast to size_t.
392 (mark_object_loop_halt): Mark as externally visible.
394 * xselect.c: Integer signedness and overflow fixes.
395 (Fx_register_dnd_atom, x_handle_dnd_message):
396 Use ptrdiff_t, not size_t, since we prefer signed.
397 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
398 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
399 x_dnd_atoms_size and x_dnd_atoms_length.
401 * doprnt.c: Prefer signed to unsigned when either works.
405 * xdisp.c (vmessage):
406 Use ptrdiff_t, not size_t, when using or implementing doprnt,
407 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
408 prefer signed arithmetic to avoid comparison confusion.
409 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
412 Assume freestanding C89 headers, string.h, stdlib.h.
413 * data.c, doprnt.c, floatfns.c, print.c:
414 Include float.h unconditionally.
415 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
416 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
417 * regex.c: Likewise for stddef.h, string.h.
418 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
419 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
420 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
421 (STDC_HEADERS): Remove obsolete defines.
422 * sysdep.c: Include limits.h unconditionally.
424 Assume support for memcmp, memcpy, memmove, memset.
425 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
426 * regex.c (memcmp, memcpy):
427 Remove; we assume C89 now.
429 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
430 (__malloc_safe_bcopy): Remove; no longer needed.
432 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
433 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
434 well either way, and we prefer signed to unsigned.
436 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
439 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
440 and the surrounding thread.
441 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
442 rather than fgets, and retry after EINTR. Otherwise, 'emacs
443 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
445 * s/openbsd.h (BROKEN_SIGIO): Define.
446 * unexelf.c (unexec) [__OpenBSD__]:
447 Don't update the .mdebug section of the Alpha COFF symbol table.
449 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
451 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
454 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
456 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
457 This fixes some race conditions on the permissions of any newly
460 * alloc.c (valid_pointer_p): Use pipe, not open.
461 This fixes some permissions issues when debugging.
463 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
464 If fchown fails to set both uid and gid, try to set just gid,
465 as that is sometimes allowed. Adjust the file's mode to eliminate
466 setuid or setgid bits that are inappropriate if fchown fails.
468 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>

486 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
487 This works around a problem with the previous change to Fcopy_file.
488 Recent glibc declares fchown with __attribute__((warn_unused_result)),
489 and without this change, GCC might complain about discarding
490 fchown's return value.
492 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
494 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

500 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
502 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
503 it's used from the C level.
505 * process.c: Use the same condition for POLL_FOR_INPUT in both
506 keyboard.c and process.c (bug#1858).

515 * doc.c (Fsubstitute_command_keys): Revert last change.
517 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
519 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
520 quotes the next character, and doesn't affect other longer
521 sequences (bug#8935).
523 * lread.c (syms_of_lread): Clarify that is isn't only
524 `eval-buffer' and `eval-defun' that's affected by
525 `lexical-binding' (bug#8460).

535 Fix minor problems found by static checking.
536 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
537 (elsz): Now a signed constant, not a size_t var. We prefer signed
538 types to unsigned, to avoid integer comparison confusion. Without
539 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
540 "cannot optimize loop, the loop counter may overflow", a symptom
542 * indent.c (Fvertical_motion): Mark locals as initialized.
543 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
545 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
547 * search.c (Fre_search_backward): Mention `case-fold-search' in
548 all the re_search_* functions (bug#8138).
550 * keyboard.c (Fopen_dribble_file): Document when the file is

589 the iterator is before prev_stop.
590 (init_iterator): Initialize bidi_p from the default value of
591 bidi-display-reordering, not from buffer-local value. Use the
592 buffer-local value only if initializing for buffer iteration.

651 popping after iteration over a string that came from a display
652 property. Fix a typo in popping stretch info. Add an assertion
653 for verifying that the iterator position is in sync with the bidi

1105 Random fixes. E.g., (random) never returned negative values.
1106 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
1107 subseconds part to the entropy, as that's a bit more random.
1108 Prefer signed to unsigned, since the signedness doesn't matter and
1109 in general we prefer signed. When given a limit, use a
1110 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
1111 latter isn't right if USE_2_TAGS_FOR_INTS.
1112 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
1113 not 0..VALMASK. Don't discard "excess" bits that random () returns.

1126 This is more efficient than Ffile_directory_p and avoids a minor race.
1128 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
1130 * buffer.c (Foverlay_put): Say what the return value is
1133 * fileio.c (barf_or_query_if_file_exists): Check first if the file

1136 (barf_or_query_if_file_exists): Make the "File is a directory"
1137 error be more correct.
1139 * fns.c (Frequire): Remove the mention of the .gz files, since
1140 that's installation-specific, but keep the mention of
1141 `get-load-suffixes'.
1143 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
1145 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

1156 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

1258 * eval.c (struct backtrace): Simplify and port the data structure.
1259 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
1260 signed bit field, as this assumption is not portable and it makes
1261 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
1262 "char debug_on_exit : 1" as this is not portable either; instead,
1263 use the portable "unsigned int debug_on_exit : 1". Remove unused
1264 member evalargs. Remove obsolete comments about cc bombing out.

1426 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
1428 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
1430 Integer and buffer overflow fixes (Bug#8873).
1432 * print.c (printchar, strout): Check for string overflow.
1433 (PRINTPREPARE, printchar, strout):
1434 Don't set size unless allocation succeeds.
1436 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
1437 for sizes. Check for string overflow more accurately.
1438 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
1440 * macros.c: Integer and buffer overflow fixes.
1441 * keyboard.h (struct keyboard.kbd_macro_bufsize):
1442 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
1443 Use ptrdiff_t, not int, for sizes.
1444 Don't increment bufsize until after realloc succeeds.
1445 Check for size-calculation overflow.
1446 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
1448 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
1450 * lread.c: Integer overflow fixes.
1451 (read_integer): Radix is now EMACS_INT, not int,
1452 to improve quality of diagnostics for out-of-range radices.
1453 Calculate buffer size correctly for out-of-range radices.
1454 (read1): Check for integer overflow in radices, and in
1455 read-circle numbers.
1456 (read_escape): Avoid int overflow.
1457 (Fload, openp, read_buffer_size, read1)
1458 (substitute_object_recurse, read_vector, read_list, map_obarray):
1459 Use ptrdiff_t, not int, for sizes.
1460 (read1): Use EMACS_INT, not int, for sizes.
1461 Check for size overflow.
1463 * image.c (cache_image): Check for size arithmetic overflow.
1465 * lread.c: Integer overflow issues.
1466 (saved_doc_string_size, saved_doc_string_length)
1467 (prev_saved_doc_string_size, prev_saved_doc_string_length):
1468 Now ptrdiff_t, not int.
1469 (read1): Don't assume doc string length fits in int. Check for
1470 out-of-range doc string lengths.
1471 (read_list): Don't assume file position fits in int.
1472 (read_escape): Check for hex character overflow.
1474 2011-06-22 Leo Liu <sdl.web@gmail.com>
1476 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
1477 Move to minibuffer.el.
1479 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
1481 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
1482 The following patches are for when GLYPH_DEBUG && !XASSERT.
1483 * dispextern.h (trace_redisplay_p, dump_glyph_string):
1484 * dispnew.c (flush_stdout):
1485 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
1486 Mark as externally visible.
1487 * dispnew.c (check_window_matrix_pointers): Now static.
1488 * dispnew.c (window_to_frame_vpos):
1489 * xfns.c (unwind_create_frame):
1490 * xterm.c (x_check_font): Remove unused local.
1491 * scroll.c (CHECK_BOUNDS):
1492 * xfaces.c (cache_fache): Rename local to avoid shadowing.
1493 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
1494 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
1495 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
1496 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
1498 (debug_method_add): Use va_list and vsprintf rather than relying
1499 on undefined behavior with wrong number of arguments.
1500 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
1501 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
1502 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
1503 since we're not interested in debugging glyphs with old libraries.
1504 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
1505 GCC 4.6.0's static checking.
1507 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
1509 Integer overflow and signedness fixes (Bug#8873).
1510 A few related buffer overrun fixes, too.
1512 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
1514 * dispextern.h (struct face.stipple):
1515 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
1516 (x_bitmap_mask, x_allocate_bitmap_record)
1517 (x_create_bitmap_from_data, x_create_bitmap_from_file)
1518 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)

1521 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
1523 * xfaces.c (load_pixmap):
1524 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
1525 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
1526 (.bitmaps_last, struct x_output.icon_bitmap):
1527 Use ptrdiff_t, not int, for bitmap indexes.
1528 (x_allocate_bitmap_record): Check for size overflow.
1529 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
1531 Use ptrdiff_t, not int, for overlay counts.
1532 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
1533 * editfns.c (overlays_around, get_pos_property):
1534 * textprop.c (get_char_property_and_overlay):
1535 * xdisp.c (next_overlay_change, note_mouse_highlight):
1536 * xfaces.c (face_at_buffer_position):
1537 * buffer.c (OVERLAY_COUNT_MAX): New macro.
1538 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
1539 (Fnext_overlay_change, Fprevious_overlay_change)
1540 (mouse_face_overlay_overlaps, Foverlays_in):
1541 Use ptrdiff_t, not int, for sizes.
1542 (overlays_at, overlays_in): Check for size-calculation overflow.
1544 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
1546 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
1547 (x_session_initialize): Do not assume string length fits in int.
1549 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
1550 This is unlikely, but can occur if DPI is outlandish.
1552 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
1553 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
1555 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
1556 * xrdb.c (magic_file_p, search_magic_path):
1557 Omit last arg SUFFIX; it was always 0. All callers changed.
1558 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
1560 * xfont.c (xfont_match): Avoid need for strlen.
1562 * xfns.c: Don't assume strlen fits in int.
1563 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
1565 * xdisp.c (message_log_check_duplicate): Return intmax_t,
1566 not unsigned long, as we prefer signed integers. All callers changed.
1567 Detect integer overflow in repeat count.
1568 (message_dolog): Don't assume print length fits in 39 bytes.
1569 (display_mode_element): Don't assume strlen fits in int.
1571 * termcap.c: Don't assume sizes fit in int and never overflow.
1572 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
1573 (gobble_line): Check for size-calculation overflow.
1575 * minibuf.c (Fread_buffer):
1576 * lread.c (intern, intern_c_string):
1577 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
1578 Don't assume string length fits in int.
1580 * keyboard.c (parse_tool_bar_item):
1581 * gtkutil.c (style_changed_cb): Avoid need for strlen.
1583 * font.c: Don't assume string length fits in int.
1584 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
1585 Use ptrdiff_t, not int.
1586 (font_intern_prop): Don't assume string length fits in int.
1587 Don't assume integer property fits in fixnum.
1588 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
1590 * filelock.c: Fix some buffer overrun and integer overflow issues.
1591 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
1592 Reformulate so as not to need the command string.
1593 Invoke gzip -cd rather than gunzip, as it's more portable.
1594 (lock_info_type, lock_file_1, lock_file):
1595 Don't assume pid_t and time_t fit in unsigned long.
1596 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
1597 (current_lock_owner): Prefer signed type for sizes.
1598 Use memcpy, not strncpy, where memcpy is what is really wanted.
1599 Don't assume (via atoi) that time_t and pid_t fit in int.
1600 Check for time_t and/or pid_t out of range, e.g., via a network share.
1601 Don't alloca where an auto var works fine.
1603 * fileio.c: Fix some integer overflow issues.
1604 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
1605 Don't assume string length fits in int.
1606 (directory_file_name): Don't assume string length fits in long.
1607 (make_temp_name): Don't assume pid fits in int, or that its print
1608 length is less than 20.
1610 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
1612 * coding.c (make_subsidiaries): Don't assume string length fits in int.
1614 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
1616 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
1617 We prefer signed integers, even for size calculations.
1619 * emacs.c: Don't assume string length fits in 'int'.
1620 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
1621 (main): Don't invoke strlen when not needed.
1623 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
1624 (XD_DEBUG_MESSAGE): Don't waste a byte.
1626 * callproc.c (getenv_internal_1, getenv_internal)
1628 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
1630 * lread.c (invalid_syntax): Omit length argument.
1631 All uses changed. This doesn't fix a bug, but it simplifies the
1632 code away from its former Hollerith-constant appearance, and it's
1633 one less 'int' to worry about when looking at integer-overflow issues.
1634 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
1636 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
1637 This didn't break anything, but it didn't help either.
1638 It's confusing to put a bogus integer in a place where the actual
1639 value does not matter.
1640 (LIST_END_P): Remove unused macro and its bogus comment.
1641 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
1643 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
1644 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
1646 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
1647 We prefer signed types, and the value cannot exceed the EMACS_INT
1648 range anyway (because otherwise the length would not be representable).
1649 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
1650 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
1651 This avoids a GCC warning when WIDE_EMACS_INT.
1653 * indent.c (sane_tab_width): New function.
1654 (current_column, scan_for_column, Findent_to, position_indentation)
1655 (compute_motion): Use it. This is just for clarity.
1656 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
1658 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
1660 * lisp.h (lint_assume): New macro.
1661 * composite.c (composition_gstring_put_cache):
1662 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
1664 * editfns.c, insdel.c:
1665 Omit unnecessary forward decls, to simplify future changes.
1667 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
1669 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
1671 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
1672 Use much-faster test for byte-length change.
1673 Don't assume string byte-length fits in 'int'.
1674 Check that character arg fits in 'int'.
1675 (mapcar1): Declare byte as byte, for clarity.
1677 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
1679 * fns.c (concat): Catch string overflow earlier.
1680 Do not rely on integer wraparound.
1682 * dispextern.h (struct it.overlay_strings_charpos)
1683 (struct it.selective): Now EMACS_INT, not int.
1684 * xdisp.c (forward_to_next_line_start)
1685 (back_to_previous_visible_line_start)
1686 (reseat_at_next_visible_line_start, next_element_from_buffer):
1687 Don't arbitrarily truncate the value of 'selective' to int.
1689 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
1691 * composite.c: Don't truncate sizes to 'int'.
1692 (composition_gstring_p, composition_reseat_it)
1693 (composition_adjust_point): Use EMACS_INT, not int.
1694 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
1695 not EMACS_UINT, for indexes.
1697 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
1699 * buffer.c: Include <verify.h>.
1700 (struct sortvec.priority, struct sortstr.priority):
1701 Now EMACS_INT, not int.
1702 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
1703 (struct sortstr.size, record_overlay_string)
1704 (struct sortstrlist.size, struct sortlist.used):
1705 Don't truncate size to int.
1706 (record_overlay_string): Check for size-calculation overflow.
1707 (init_buffer_once): Check at compile-time, not run-time.
1709 2011-06-22 Jim Meyering <meyering@redhat.com>
1711 Don't leak an XBM-image-sized buffer
1712 * image.c (xbm_load): Free the image buffer after using it.
1714 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
1717 * composite.c (find_automatic_composition): Omit needless 'return 0;'
1718 that Sun C diagnosed.
1719 * fns.c (secure_hash): Fix pointer signedness issue.
1720 * intervals.c (static_offset_intervals): New function.
1721 (offset_intervals): Use it.
1723 2011-06-21 Leo Liu <sdl.web@gmail.com>
1726 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
1729 * fns.c (secure_hash): Rename from crypto_hash_function and change
1730 the first arg to accept symbols.
1731 (Fsecure_hash): New primitive.
1732 (syms_of_fns): New symbols.
1734 2011-06-20 Deniz Dogan <deniz@dogan.se>
1736 * process.c (Fset_process_buffer): Clarify return value in
1739 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
1741 * dispnew.c (add_window_display_history): Use BVAR.
1743 * xdisp.c (debug_method_add): Use BVAR.
1744 (check_window_end, dump_glyph_matrix, dump_glyph)
1745 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
1747 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
1750 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
1751 check till after the cache is created in init_frame_faces.
1753 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
1755 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
1757 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
1759 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
1760 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
1761 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
1763 Improve buffer-overflow checking (Bug#8873).
1764 * fileio.c (Finsert_file_contents):
1765 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
1766 Remove the old (too-loose) buffer overflow checks.
1767 They weren't needed, since make_gap checks for buffer overflow.
1768 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
1769 The old code merely checked for Emacs fixnum overflow, and relied
1770 on undefined (wraparound) behavior. The new code avoids undefined
1771 behavior, and also checks for ptrdiff_t and/or size_t overflow.
1773 * editfns.c (Finsert_char): Don't dump core with very negative counts.
1774 Tune. Don't use wider integers than needed. Don't use alloca.
1775 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
1777 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
1779 * insdel.c, lisp.h (buffer_overflow): New function.
1780 (insert_from_buffer_1, replace_range, replace_range_2):
1781 * insdel.c (make_gap_larger):
1782 * editfns.c (Finsert_char):
1783 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
1785 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
1787 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
1789 Integer overflow and signedness fixes (Bug#8873).
1791 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
1792 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
1794 * fileio.c: Don't assume EMACS_INT fits in off_t.
1795 (emacs_lseek): New static function.
1796 (Finsert_file_contents, Fwrite_region): Use it.
1797 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
1799 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
1801 * fns.c: Don't overflow int when computing a list length.
1802 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
1803 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
1804 truncation on 64-bit hosts. Check for QUIT every
1805 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
1806 faster and is responsive enough.
1807 (Flength): Report an error instead of overflowing an integer.
1808 (Fsafe_length): Return a float if the value is not representable
1809 as a fixnum. This shouldn't happen except in contrived situations.
1810 (Fnthcdr, Fsort): Don't assume list length fits in int.
1811 (Fcopy_sequence): Don't assume vector length fits in int.
1813 * alloc.c: Check that resized vectors' lengths fit in fixnums.
1814 (header_size, word_size): New constants.
1815 (allocate_vectorlike): Don't check size overflow here.
1816 (allocate_vector): Check it here instead, since this is the only
1817 caller of allocate_vectorlike that could cause overflow.
1818 Check that the new vector's length is representable as a fixnum.
1820 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
1821 The previous code was bogus. For example, next_almost_prime (32)
1822 returned 39, which is undesirable as it is a multiple of 3; and
1823 next_almost_prime (24) returned 25, which is a multiple of 5 so
1824 why was the code bothering to check for multiples of 7?
1826 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
1828 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
1830 Variadic C functions now count arguments with ptrdiff_t.
1831 This partly undoes my 2011-03-30 change, which replaced int with size_t.
1832 Back then I didn't know that the Emacs coding style prefers signed int.
1833 Also, in the meantime I found a few more instances where arguments
1834 were being counted with int, which may truncate counts on 64-bit
1835 machines, or EMACS_INT, which may be unnecessarily wide.
1836 * lisp.h (struct Lisp_Subr.function.aMANY)
1837 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
1838 Arg counts are now ptrdiff_t, not size_t.
1839 All variadic functions and their callers changed accordingly.
1840 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
1841 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
1842 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
1843 * callint.c (Fcall_interactively): Check arg count for overflow,
1844 to avoid potential buffer overrun. Use signed char, not 'int',
1845 for 'varies' array, so that we needn't bother to check its size
1846 calculation for overflow.
1847 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
1848 * eval.c (apply_lambda):
1849 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
1850 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
1851 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
1853 * callint.c (Fcall_interactively): Don't use index var as event count.
1855 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
1856 * mem-limits.h (SIZE): Remove; no longer used.
1858 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
1860 Remove unnecessary casts.
1861 * xterm.c (x_term_init):
1862 * xfns.c (x_set_border_pixel):
1863 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
1864 These aren't needed now that we assume ANSI C.
1866 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
1867 It's more likely to cause problems (due to unsigned overflow)
1870 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
1872 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
1874 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
1876 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
1878 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
1880 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
1882 GLYPH_CODE_FACE returns EMACS_INT, not int.
1883 * dispextern.h (merge_faces):
1884 * xfaces.c (merge_faces):
1885 * xdisp.c (get_next_display_element, next_element_from_display_vector):
1886 Don't assume EMACS_INT fits in int.
1888 * character.h (CHAR_VALID_P): Remove unused parameter.
1889 * fontset.c, lisp.h, xdisp.c: All uses changed.
1891 * editfns.c (Ftranslate_region_internal): Omit redundant test.
1893 * fns.c (concat): Minor tuning based on overflow analysis.
1894 This doesn't fix any bugs. Use int to hold character, instead
1895 of constantly refetching from Emacs object. Use XFASTINT, not
1896 XINT, for value known to be a character. Don't bother comparing
1897 a single byte to 0400, as it's always less.
1899 * floatfns.c (Fexpt):
1900 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
1902 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
1905 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
1907 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
1908 Without this fix, on a 64-bit host (aset S 0 4294967386) would
1909 incorrectly succeed when S was a string, because 4294967386 was
1910 truncated before it was used.
1912 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
1913 Otherwise, an out-of-range integer could cause undefined behavior
1916 * composite.c: Use int, not EMACS_INT, for characters.
1917 (fill_gstring_body, composition_compute_stop_pos): Use int, not
1918 EMACS_INT, for values that are known to be in character range.
1919 This doesn't fix any bugs but is the usual style inside Emacs and
1920 may generate better code on 32-bit machines.
1922 Make sure a 64-bit char is never passed to ENCODE_CHAR.
1923 This is for reasons similar to the recent CHAR_STRING fix.
1924 * charset.c (Fencode_char): Check that character arg is actually
1925 a character. Pass an int to ENCODE_CHAR.
1926 * charset.h (ENCODE_CHAR): Verify that the character argument is no
1927 wider than 'int', as a compile-time check to prevent future regressions
1930 * character.c (char_string): Remove unnecessary casts.
1932 Make sure a 64-bit char is never passed to CHAR_STRING.
1933 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
1934 by silently ignoring the top 32 bits, allowing some values
1935 that were far too large to be valid characters.
1936 * character.h: Include <verify.h>.
1937 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
1938 arguments are no wider than unsigned, as a compile-time check
1939 to prevent future regressions in this area.
1941 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
1942 (Fsubst_char_in_region):
1944 * xdisp.c (decode_mode_spec_coding):
1945 Adjust to CHAR_STRING's new requirement.
1946 * editfns.c (Finsert_char, Fsubst_char_in_region):
1947 * fns.c (concat): Check that character args are actually
1948 characters. Without this test, these functions did the wrong
1949 thing with wildly out-of-range values on 64-bit hosts.
1951 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
1952 These casts should not be needed on 32-bit hosts, either.
1953 * keyboard.c (read_char):
1954 * lread.c (Fload): Remove casts to unsigned.
1956 * lisp.h (UNSIGNED_CMP): New macro.
1957 This fixes comparison bugs on 64-bit hosts.
1958 (ASCII_CHAR_P): Use it.
1959 * casefiddle.c (casify_object):
1960 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
1961 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
1962 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
1963 * dispextern.h (FACE_FROM_ID):
1964 * keyboard.c (read_char): Use UNSIGNED_CMP.
1966 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
1967 not to EMACS_INT, to avoid GCC warning.
1969 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
1971 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
1972 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
1973 isn't needed on 32-bit machines.
1975 * buffer.c (Fgenerate_new_buffer_name):
1976 Use EMACS_INT for count, not int.
1977 (advance_to_char_boundary): Return EMACS_INT, not int.
1979 * data.c (Qcompiled_function): Now static.
1981 * window.c (window_body_lines): Now static.
1983 * image.c (gif_load): Rename local to avoid shadowing.
1985 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
1986 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
1987 * alloc.c (make_save_value): Integer argument is now of type
1989 (mark_object): Use ptrdiff_t, not int.
1990 * lisp.h (pD): New macro.
1991 * print.c (print_object): Use it.
1993 * alloc.c: Use EMACS_INT, not int, to count objects.
1994 (total_conses, total_markers, total_symbols, total_vector_size)
1995 (total_free_conses, total_free_markers, total_free_symbols)
1996 (total_free_floats, total_floats, total_free_intervals)
1997 (total_intervals, total_strings, total_free_strings):
1998 Now EMACS_INT, not int. All uses changed.
1999 (Fgarbage_collect): Compute overall total using a double, so that
2000 integer overflow is less likely to be a problem. Check for overflow
2001 when converting back to an integer.
2002 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
2003 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
2004 These were 'int' variables that could overflow on 64-bit hosts;
2005 they were never used, so remove them instead of repairing them.
2006 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
2007 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
2008 Previously, this ceilinged at INT_MAX, but that doesn't work on
2010 (allocate_pseudovector): Don't use EMACS_INT when int would do.
2012 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
2013 (allocate_vectorlike): Check for ptrdiff_t overflow.
2014 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
2015 when a (possibly-narrower) signed value would do just as well.
2016 We prefer using signed arithmetic, to avoid comparison confusion.
2018 * alloc.c: Catch some string size overflows that we were missing.
2019 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
2020 for convenience in STRING_BYTES_MAX.
2021 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
2022 The definition here is exact; the one in lisp.h was approximate.
2023 (allocate_string_data): Check for string overflow. This catches
2024 some instances we weren't catching before. Also, it catches
2025 size_t overflow on (unusual) hosts where SIZE_MAX <= min
2026 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
2027 and ptrdiff_t and EMACS_INT are both 64 bits.
2029 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
2030 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
2031 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
2033 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
2035 * alloc.c (Fmake_string): Check for out-of-range init.
2037 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
2039 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
2041 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
2043 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
2044 xg_get_default_scrollbar_width.

2050 all frames (Bug#8505).
2051 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
2052 Call gtk_window_set_resizable if HAVE_GTK3.
2053 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
2054 and height if HAVE_GTK3 (Bug#8505).
2055 (scroll_bar_width_for_theme): New variable.
2056 (update_theme_scrollbar_width): New function.
2057 (xg_get_default_scrollbar_width): Move code to
2058 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
2059 (xg_initialize): Call update_theme_scrollbar_width.
2061 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
2063 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
2065 2011-06-12 Martin Rudalics <rudalics@gmx.at>
2067 * frame.c (make_frame): Call other_buffer_safely instead of
2070 * window.c (temp_output_buffer_show): Call display_buffer with
2071 second argument Vtemp_buffer_show_specifiers and reset latter
2072 immediately after the call.
2073 (Vtemp_buffer_show_specifiers): New variable.
2074 (auto_window_vscroll_p, next_screen_context_lines)
2075 (Vscroll_preserve_screen_position): Remove leading asterisks from

2672 Without this change, the gnutls library would invoke malloc etc.
2673 directly, which causes problems on non-SYNC_INPUT hosts, and which
2674 runs afoul of improving memory_full behavior. (Bug#8761)
2675 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
2676 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
2677 xfree instead of the default malloc, realloc, free.
2678 (Fgnutls_boot): No need to check for memory allocation failure,
2679 since xmalloc does that for us.

2704 Check for overflow in vector size calculations.
2705 * ccl.c (ccl_driver):
2706 Check for overflow when converting EMACS_INT to int.
2707 * fns.c, image.c: Remove unnecessary static decls that would otherwise

2710 Check for integer overflow with large hash tables.
2711 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
2712 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
2713 (SXHASH_REDUCE): New macro.
2714 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
2715 Use it instead of discarding useful hash info with large hash values.
2716 (sxhash_float): New function.
2717 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
2718 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
2719 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
2720 Rewrite to use FIXNUM_BITS, as this simplifies things.
2721 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
2722 Adjust signatures to match updated version of code.
2723 (consing_since_gc): Now EMACS_INT, since a single hash table can

2766 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
2767 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
2768 * gmalloc.c (register_heapinfo): Use inline unconditionally.
2769 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
2771 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
2773 Make it possible to run ./temacs.
2775 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
2776 syms_of_callproc does the same thing. Remove test for
2777 "initialized", do it in the caller.
2778 * emacs.c (main): Avoid calling set_initial_environment when dumping.
2780 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
2782 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
2783 (read_minibuf): Use get_minibuffer.
2784 (syms_of_minibuf): Use DEFSYM.
2785 (Qmetadata): New var.
2786 * data.c (Qbuffer): Don't make it static.
2787 (syms_of_data): Use DEFSYM.
2789 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
2791 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
2792 (CCL_CODE_MIN): New macro.
2794 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
2796 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
2798 * eval.c (Qdebug): Now static.
2799 * lisp.h (Qdebug): Remove decl. This reverts a part of the
2800 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
2801 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
2803 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
2805 * image.c: Various fixes to ImageMagick code comments.
2806 (Fimagemagick_types): Doc fix.
2808 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
2810 Minor fixes prompted by GCC 4.6.0 warnings.
2812 * xselect.c (converted_selections, conversion_fail_tag): Now static.
2814 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
2815 (x_clipboard_manager_save_all): Move extern decl to ...
2816 * xterm.h: ... here, so that it can be checked for consistency.
2818 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
2820 * xselect.c (x_clipboard_manager_save_frame)
2821 (x_clipboard_manager_save_all): New functions.
2822 (Fx_clipboard_manager_save): Lisp function deleted.
2824 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
2825 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
2827 * xterm.h: Update prototype.
2829 2011-05-28 William Xu <william.xwl@gmail.com>
2831 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
2834 2011-05-28 Jim Meyering <meyering@redhat.com>
2836 Avoid a sign-extension bug in crypto_hash_function.
2837 * fns.c (to_uchar): Define.
2838 (crypto_hash_function): Use it to convert some newly-signed
2839 variables to unsigned, to avoid sign-extension bugs. For example,
2840 without this change, (md5 "truc") would evaluate to
2841 45723a2aff78ff4fff7fff1114760e62 rather than the expected
2842 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
2843 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
2845 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
2847 Integer overflow fixes.
2849 * dbusbind.c: Serial number integer overflow fixes.
2850 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
2851 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
2852 to hold a serial number that is too large for a fixnum.
2853 (Fdbus_method_return_internal, Fdbus_method_error_internal):
2854 Check for serial numbers out of range. Decode any serial number
2855 that was so large that it became a float. (Bug#8722)
2857 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
2858 (Fdbus_call_method, Fdbus_call_method_asynchronously):
2859 Use XFASTINT rather than XUINT when numbers are nonnegative.
2860 (xd_append_arg, Fdbus_method_return_internal):
2861 (Fdbus_method_error_internal): Likewise. Also, for unsigned
2862 arguments, check that Lisp number is nonnegative, rather than
2863 silently wrapping negative numbers around. (Bug#8722)
2864 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
2867 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
2869 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
2871 ccl: add integer overflow checks
2872 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
2873 (IN_INT_RANGE): New macros.
2874 (ccl_driver): Use them to check for integer overflow when
2875 decoding a CCL program. Many of the new checks are whether XINT (x)
2876 fits in int; it doesn't always, on 64-bit hosts. The new version
2877 doesn't catch all possible integer overflows, but it's an
2878 improvement. (Bug#8719)
2880 * alloc.c (make_event_array): Use XINT, not XUINT.
2881 There's no need for unsigned here.
2883 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
2884 This follows up to the 2011-05-06 change that substituted uintptr_t
2885 for EMACS_INT. This case wasn't caught back then.
2887 Rework Fformat to avoid integer overflow issues.
2888 * editfns.c: Include <float.h> unconditionally, as it's everywhere
2889 now (part of C89). Include <verify.h>.
2890 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
2891 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
2892 (Fformat): Avoid the prepass trying to compute sizes; it was only
2893 approximate and thus did not catch overflow reliably. Instead, walk
2894 through the format just once, formatting and computing sizes as we go,
2895 checking for integer overflow at every step, and allocating a larger
2896 buffer as needed. Keep track separately whether the format is
2897 multibyte. Keep only the most-recently calculated precision, rather
2898 than them all. Record whether each argument has been converted to
2899 string. Use EMACS_INT, not int, for byte and char and arg counts.
2900 Support field widths and precisions larger than INT_MAX. Avoid
2901 sprintf's undefined behavior with conversion specifications such as %#d
2902 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
2903 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
2904 formatting out-of-range floating point numbers with int
2907 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
2909 * data.c: Avoid integer truncation in expressions involving floats.
2910 * data.c: Include <intprops.h>.
2911 (arith_driver): When there's an integer overflow in an expression
2912 involving floating point, convert the integers to floating point
2913 so that the resulting value does not suffer from catastrophic
2914 integer truncation. For example, on a 64-bit host (* 4
2915 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
2916 Do not rely on undefined behavior after integer overflow.
2918 merge count_size_as_multibyte, parse_str_to_multibyte
2919 * character.c, character.h (count_size_as_multibyte):
2920 Rename from parse_str_to_multibyte; all uses changed.
2921 Check for integer overflow.
2922 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
2923 since it's now a duplicate of the other. This is more of
2924 a character than a buffer op, so better that it's in character.c.
2925 * fns.c, print.c: Adjust to above changes.
2927 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
2929 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
2931 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
2933 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
2934 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
2935 (x_clipboard_manager_save): Now static.
2936 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
2938 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
2939 (crypto_hash_function): Now static.
2940 Fix pointer signedness problems. Avoid unnecessary initializations.
2942 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
2944 * termhooks.h (Vselection_alist): Make it terminal-local.
2946 * terminal.c (create_terminal): Initialize it.
2948 * xselect.c: Support for clipboard managers.
2949 (Vselection_alist): Move to termhooks.h as terminal-local var.
2950 (LOCAL_SELECTION): New macro.
2951 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
2952 (symbol_to_x_atom): Remove gratuitous arg.
2953 (x_handle_selection_request, lisp_data_to_selection_data)
2954 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
2955 (x_own_selection, x_get_local_selection, x_convert_selection):
2956 New arg, specifying work frame. Use terminal-local Vselection_alist.
2957 (some_frame_on_display): Delete unused function.
2958 (Fx_own_selection_internal, Fx_get_selection_internal)
2959 (Fx_disown_selection_internal, Fx_selection_owner_p)
2960 (Fx_selection_exists_p): New optional frame arg.
2961 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
2962 (x_handle_selection_clear): Don't treat other terminals with the
2963 same keyboard specially. Use the terminal-local Vselection_alist.
2964 (x_clear_frame_selections): Use Frun_hook_with_args.
2966 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
2968 * xterm.h: Add support for those atoms.
2970 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
2972 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
2973 (converted_selections, conversion_fail_tag): New global variables.
2974 (x_selection_request_lisp_error): Free the above.
2975 (x_get_local_selection): Remove unnecessary code.
2976 (x_reply_selection_request): Args changed; handle arbitrary array
2977 of converted selections stored in converted_selections.
2978 Separate the XChangeProperty and SelectionNotify steps.
2979 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
2980 (x_convert_selection): New function.
2981 (x_handle_selection_event): Simplify.
2982 (x_get_foreign_selection): Don't ignore incoming requests while
2983 waiting for an answer; this will fail when we implement
2984 SAVE_TARGETS, and seems unnecessary anyway.
2985 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
2986 (Vx_sent_selection_functions): Doc fix.
2988 2011-05-26 Leo Liu <sdl.web@gmail.com>
2990 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
2992 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2994 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
2996 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
2997 for fringe update if it has periodic bitmap.
2998 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
2999 and fringe_bitmap_periodic_p.
3001 * fringe.c (get_fringe_bitmap_data): New function.
3002 (draw_fringe_bitmap_1, update_window_fringes): Use it.
3003 (update_window_fringes): Record periodicity of fringe bitmap in glyph
3004 row. Mark glyph row for fringe update if periodicity changed.
3006 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
3007 for fringe update unless it has periodic bitmap.
3009 2011-05-25 Kenichi Handa <handa@m17n.org>
3011 * xdisp.c (get_next_display_element): Set correct it->face_id for
3012 a static composition.
3014 2011-05-24 Leo Liu <sdl.web@gmail.com>
3017 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
3019 * fns.c (crypto_hash_function, Fsha1): New function.
3020 (Fmd5): Use crypto_hash_function.
3021 (syms_of_fns): Add Ssha1.
3023 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3025 * gnutls.c: Remove unused macros.
3026 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
3027 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
3028 Remove macros that are defined and never used.
3029 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
3031 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3033 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
3034 (Fx_get_selection_internal): Minor cleanup.
3035 (Fx_own_selection_internal): Rename arguments for consistency with
3038 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3040 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
3042 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3044 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
3046 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3048 * dispnew.c (scrolling_window): Don't exclude the case that the
3049 last enabled row in the desired matrix touches the bottom boundary.
3051 2011-05-21 Glenn Morris <rgm@gnu.org>
3053 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
3054 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
3055 and add some more files.
3057 2011-05-20 Eli Zaretskii <eliz@gnu.org>
3059 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
3060 report_file_error introduced by the change from 2011-05-07.
3062 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
3064 * systime.h (Time): Define only if emacs is defined.
3065 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
3066 where the include path doesn't have X11/X.h by default. See
3067 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
3069 2011-05-20 Kenichi Handa <handa@m17n.org>
3071 * composite.c (find_automatic_composition): Fix previous change.
3073 2011-05-20 Glenn Morris <rgm@gnu.org>
3075 * lisp.mk: New file, split from Makefile.in.
3076 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
3077 (shortlisp): Remove.
3078 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
3080 2011-05-19 Glenn Morris <rgm@gnu.org>
3082 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
3083 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
3084 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
3085 (lisp): Set the order to that of loadup.el.
3086 (shortlisp): Make it a copy of $lisp.
3087 (SOME_MACHINE_LISP): Remove.
3088 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
3089 Use just $shortlisp, not $SOME_MACHINE_LISP too.
3091 2011-05-18 Kenichi Handa <handa@m17n.org>
3093 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
3094 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
3095 (find_automatic_composition): Mostly rewrite for efficiency.
3097 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
3099 * makefile.w32-in: Update dependencies.
3101 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
3103 * menu.c: Include limits.h (fixes the MS-Windows build broken by
3104 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
3106 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
3108 Fix some integer overflow issues, such as string length overflow.
3110 * insdel.c (count_size_as_multibyte): Check for string overflow.
3112 * character.c (lisp_string_width): Check for string overflow.
3113 Use EMACS_INT, not int, for string indexes and lengths; in
3114 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
3115 the resulting string length overflows an EMACS_INT; instead,
3116 report a string overflow if no precision given. When checking for
3117 precision exhaustion, use a check that cannot possibly have
3118 integer overflow. (Bug#8675)
3119 * character.h (lisp_string_width): Adjust to new signature.
3121 * alloc.c (string_overflow): New function.
3122 (Fmake_string): Use it. This doesn't change behavior, but saves
3123 a few bytes and will simplify future changes.
3124 * character.c (string_escape_byte8): Likewise.
3125 * lisp.h (string_overflow): New decl.
3127 Fixups, following up to the user-interface timestamp change.
3128 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
3129 for UI timestamps, instead of unsigned long.
3130 * msdos.c (mouse_get_pos): Likewise.
3131 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
3132 * w32gui.h (Time): Define by including "systime.h" rather than by
3133 declaring it ourselves. (Bug#8664)
3135 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
3136 * image.c (clear_image_cache): Likewise.
3138 * term.c (term_mouse_position): Don't assume time_t wraparound.
3140 Be more systematic about user-interface timestamps.
3141 Before, the code sometimes used 'Time', sometimes 'unsigned long',
3142 and sometimes 'EMACS_UINT', to represent these timestamps.
3143 This change causes it to use 'Time' uniformly, as that's what X uses.
3144 This makes the code easier to follow, and makes it easier to catch
3145 integer overflow bugs such as Bug#8664.
3146 * frame.c (Fmouse_position, Fmouse_pixel_position):
3147 Use Time, not unsigned long, for user-interface timestamps.
3148 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
3149 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
3150 * keyboard.h (last_event_timestamp): Likewise.
3151 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
3152 * menu.h (xmenu_show): Likewise.
3153 * term.c (term_mouse_position): Likewise.
3154 * termhooks.h (struct input_event.timestamp): Likewise.
3155 (struct terminal.mouse_position_hook): Likewise.
3156 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
3157 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
3158 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
3159 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
3161 * menu.h, termhooks.h: Include "systime.h", for Time.
3163 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
3164 Don't assume that the difference between two unsigned long values
3165 can fit into an integer. At this point, we know button_down_time
3166 <= event->timestamp, so the difference must be nonnegative, so
3167 there's no need to cast the result if double-click-time is
3168 nonnegative, as it should be; check that it's nonnegative, just in
3169 case. This bug is triggered when events are more than 2**31 ms
3170 apart (about 25 days). (Bug#8664)
3172 * xselect.c (last_event_timestamp): Remove duplicate decl.
3173 (x_own_selection): Remove needless cast to unsigned long.
3175 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
3176 that always fit in int. Use a sentinel instead of a counter, to
3177 avoid a temp and to allay GCC's concerns about possible int overflow.
3178 * frame.h (struct frame): Use int for menu_bar_items_used
3179 instead of EMACS_INT, since it always fits in int.
3181 * menu.c (grow_menu_items): Check for int overflow.
3183 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
3185 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
3186 Before, the code was not consistent. These values cannot exceed
3187 2**31 - 1 so there's no need to make them unsigned.
3188 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
3189 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
3190 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
3192 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
3194 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
3195 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
3196 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
3197 presumably because the widths might not match.
3199 * window.c (size_window): Avoid needless test at loop start.
3201 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
3203 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
3205 2011-05-12 Drew Adams <drew.adams@oracle.com>
3207 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
3209 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3211 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
3212 `width' to `bar_area_x' and `bar_area_width', respectively.
3213 (x_scroll_run): Take account of fringe background extension.
3215 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
3216 Rename local vars `left' and `width' to `bar_area_x' and
3217 `bar_area_width', respectively.
3218 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
3219 background extension.
3221 2011-05-10 Jim Meyering <meyering@redhat.com>
3223 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
3225 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
3227 * image.c (Finit_image_library): Return t for built-in image types,
3228 like pbm and xbm. (Bug#8640)
3230 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
3232 * w32menu.c (set_frame_menubar): Fix submenu allocation.
3234 2011-05-07 Eli Zaretskii <eliz@gnu.org>
3236 * w32console.c (Fset_screen_color): Doc fix.
3237 (Fget_screen_color): New function.
3238 (syms_of_ntterm): Defsubr it.
3240 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
3241 unlink the temporary file if Fcall_process didn't create it in the
3243 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
3244 child process will be redirected to a file specified with `:file'.
3245 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
3246 cue to call_process_cleanup not to close that handle.
3248 2011-05-07 Ben Key <bkey76@gmail.com>
3250 * makefile.w32-in: The bootstrap-temacs rule now makes use of
3251 one of two shell specific rules, either bootstrap-temacs-CMD or
3252 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
3253 to the previous implementation of the bootstrap-temacs rule.
3254 The bootstrap-temacs-CMD rule is similar to the previous
3255 implementation of the bootstrap-temacs rule except that it
3256 makes use of the ESC_CFLAGS variable instead of the CFLAGS
3259 These changes, along with some changes to nt/configure.bat,
3260 nt/gmake.defs, and nt/nmake.defs, are required to extend my
3261 earlier fix to add support for --cflags and --ldflags options
3262 that include quotes so that it works whether make uses cmd or
3265 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
3267 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
3268 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
3270 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
3271 a string. Handle both cases.
3272 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
3273 (Fdbus_register_method): Use Qinvalid_function.
3275 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3277 * makefile.w32-in: Update dependencies.
3278 (LISP_H): Add inttypes.h and stdin.h.
3279 (PROCESS_H): Add unistd.h.
3281 2011-05-06 Eli Zaretskii <eliz@gnu.org>
3283 * lread.c: Include limits.h (fixes the MS-Windows build broken by
3284 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
3286 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
3288 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
3290 * term.c (vfatal): Remove stray call to va_end.
3291 It's not needed and the C Standard doesn't allow it here anyway.
3293 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
3294 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
3296 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
3299 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
3301 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3303 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
3305 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
3307 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
3309 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
3310 * charset.c (Fdefine_charset_internal): Don't initialize
3311 charset.code_space[15]. The value was garbage, on hosts with
3312 32-bit int (Bug#8600).
3314 * lread.c (read_integer): Be more consistent with string-to-number.
3315 Use string_to_number to do the actual conversion; this avoids
3316 rounding errors and fixes some other screwups. Without this fix,
3317 for example, #x1fffffffffffffff was misread as -2305843009213693952.
3318 (digit_to_number): Move earlier, for benefit of read_integer.
3319 Return -1 if the digit is out of range for the base, -2 if it is
3320 not a digit in any supported base. (Bug#8602)
3322 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
3324 * dispnew.c (scrolling_window): Return 1 if we scrolled,
3325 to match comment at start of function. This also removes a
3326 GCC warning about overflow in a 32+64-bit port.
3328 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
3330 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
3331 Reported by Stefan Monnier in
3332 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
3333 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3334 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
3336 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
3337 (EMACS_UINTPTR): Likewise, with uintptr_t.
3339 * lisp.h: Prefer 64-bit EMACS_INT if available.
3340 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
3341 on 32-bit hosts that have 64-bit int, so that they can access
3343 However, temporarily disable this change unless the temporary
3344 symbol WIDE_EMACS_INT is defined.
3346 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
3348 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
3349 This removes an assumption that EMACS_INT and long are the same
3350 width as pointers. The assumption is true for Emacs porting targets
3351 now, but we want to make other targets possible.
3352 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
3353 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
3354 In the rest of the code, change types of integers that hold casted
3355 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
3356 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
3357 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
3358 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
3359 No need to cast type when ORing.
3360 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
3361 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
3362 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
3363 assume EMACS_INT is the same width as char *.
3364 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
3365 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
3366 Remove no-longer-needed casts.
3367 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
3368 (xg_tool_bar_help_callback, xg_make_tool_item):
3369 Use EMACS_INTPTR to hold an integer
3370 that will be cast to void *; this can avoid a GCC warning
3371 if EMACS_INT is not the same width as void *.
3372 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
3373 * xdisp.c (display_echo_area_1, resize_mini_window_1):
3374 (current_message_1, set_message_1):
3375 Use a local to convert to proper width without a cast.
3376 * xmenu.c (dialog_selection_callback): Likewise.
3378 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
3379 Also, don't assume VALBITS / RAND_BITS is less than 5,
3380 and don't rely on undefined behavior when shifting a 1 left into
3382 * lisp.h (get_random): Change signature to match.
3384 * lread.c (hash_string): Use size_t, not int, for hash computation.
3385 Normally we prefer signed values; but hashing is special, because
3386 it's better to use unsigned division on hash table sizes so that
3387 the remainder is nonnegative. Also, size_t is the natural width
3388 for hashing into memory. The previous code used 'int', which doesn't
3389 retain enough info to hash well into very large tables.
3390 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
3392 * dbusbind.c: Don't possibly lose pointer info when converting.
3393 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3394 Use XPNTR rather than XHASH, so that the high-order bits of
3395 the pointer aren't lost when converting through void *.
3397 * eval.c (Fautoload): Don't double-shift a pointer.
3399 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
3401 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3403 * gnutls.c (DEF_GNUTLS_FN):
3404 * image.c (DEF_IMGLIB_FN): Make function pointers static.
3406 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
3408 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
3411 2011-05-05 Eli Zaretskii <eliz@gnu.org>
3413 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
3414 New version that can reserve upto 2GB of heap space.
3416 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
3418 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
3420 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
3422 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
3423 `gnutls_certificate_set_x509_key_file'.
3425 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
3427 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
3428 Update dependencies.
3430 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3432 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
3433 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
3434 Remove unused parameter `fildes'.
3435 * process.c (read_process_output, send_process): Don't pass it.
3437 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3439 Fix previous change: the library cache is defined in w32.c.
3440 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
3441 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
3443 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3445 Implement dynamic loading of GnuTLS on Windows.
3447 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
3448 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
3449 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
3452 * gnutls.c (Qgnutls_dll): Define.
3453 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
3454 (gnutls_*): Declare function pointers.
3455 (init_gnutls_functions): New function to initialize function pointers.
3456 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
3457 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
3458 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
3459 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
3460 (emacs_gnutls_write, emacs_gnutls_read)
3461 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
3462 (Fgnutls_available_p): New function.
3463 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
3464 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
3465 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
3467 * image.c: Include w32.h.
3468 (Vimage_type_cache): Delete.
3469 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
3470 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
3471 (w32_delayed_load): Move to w32.c.
3473 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
3475 * w32.c (QCloaded_from, Vlibrary_cache): Define.
3476 (w32_delayed_load): Move from image.c. When loading a library, record
3477 its filename in the :loaded-from property of the library id.
3478 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
3479 Initialize and staticpro them.
3480 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
3482 * process.c: Include lisp.h before w32.h, not after.
3483 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
3484 instead of gnutls_record_check_pending.
3486 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
3488 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
3490 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
3491 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
3494 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
3496 * xterm.c (x_set_frame_alpha): Do not set property on anything
3497 else than FRAME_X_OUTER_WINDOW (Bug#8608).
3499 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
3501 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
3503 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
3505 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
3506 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

3512 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
3513 (Qgnutls_bootprop_callbacks_verify): Make static.
3515 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
3517 * callproc.c: Indentation fixup.
3519 * sysdep.c (wait_for_termination_1): Make static.
3520 (wait_for_termination, interruptible_wait_for_termination):
3521 Move after wait_for_termination_1.
3523 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
3525 * sysdep.c (interruptible_wait_for_termination): New function
3526 which is like wait_for_termination, but allows keyboard
3529 * callproc.c (Fcall_process): Add (:file "file") as an option for
3531 (Fcall_process_region): Ditto.
3533 2011-04-30 Eli Zaretskii <eliz@gnu.org>
3535 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
3536 rather than `XVECTOR (FOO)->size'.
3538 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
3539 inttypes.h, as a gnulib replacement is used if it not available in
3542 2011-04-21 Eli Zaretskii <eliz@gnu.org>
3544 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
3545 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
3546 of MOST_POSITIVE_FIXNUM. (Bug#8528)
3548 * coding.c (coding_alloc_by_realloc): Error out if destination
3549 will grow beyond MOST_POSITIVE_FIXNUM.
3550 (decode_coding_emacs_mule): Abort if there isn't enough place in
3551 charbuf for the composition carryover bytes. Reserve an extra
3552 space for up to 2 characters produced in a loop.
3553 (decode_coding_iso_2022): Abort if there isn't enough place in
3554 charbuf for the composition carryover bytes.
3556 2011-04-21 Eli Zaretskii <eliz@gnu.org>
3558 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
3559 aborting when %lld or %lll format is passed.
3560 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
3561 %llo or %llx format is passed. (Bug#8545)
3563 * window.c (window_scroll_line_based): Use a marker instead of
3564 simple variables to record original value of point. (Bug#7952)
3566 * doprnt.c (doprnt): Fix the case where a multibyte sequence
3567 produced by %s or %c overflows available buffer space. (Bug#8545)
3569 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
3571 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
3572 (SIZE_MAX): Move defn after all includes, as they might #define it.
3574 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3576 * w32.c (init_environment): Warn about defaulting HOME to C:\.
3578 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3580 * keyboard.c (Qdelayed_warnings_hook): Define.
3581 (command_loop_1): Run `delayed-warnings-hook'
3582 if Vdelayed_warnings_list is non-nil.
3583 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
3584 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
3586 2011-04-28 Eli Zaretskii <eliz@gnu.org>
3588 * doprnt.c (doprnt): Don't return value smaller than the buffer
3589 size if the message was truncated. (Bug#8545).
3591 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3593 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

3596 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3598 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
3600 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
3602 * makefile.w32-in: Update dependencies.
3604 2011-04-27 Eli Zaretskii <eliz@gnu.org>
3606 Improve `doprnt' and its usage. (Bug#8545)
3607 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
3608 `format_end'. Remove support for %l as a conversion specifier.
3609 Don't use xrealloc. Improve diagnostics when the %l size modifier
3610 is used. Update the commentary.
3612 * eval.c (verror): Simplify calculation of size_t.
3614 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
3617 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
3619 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
3622 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3624 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
3625 This makes this file independent of the recent pseudovector change.
3627 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
3629 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
3631 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
3632 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
3633 Remove unused local.
3634 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
3636 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
3637 GCC 4.6.0 optimizes based on type-based alias analysis.
3638 For example, if b is of type struct buffer * and v of type struct
3639 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
3640 != &v->size, and therefore "v->size = 1; b->size = 2; return
3641 v->size;" must therefore return 1. This assumption is incorrect
3642 for Emacs, since it type-puns struct Lisp_Vector * with many other
3643 types. To fix this problem, this patch adds a new type struct
3644 vectorlike_header that documents the constraints on layout of vectors
3645 and pseudovectors, and helps optimizing compilers not get fooled
3646 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
3647 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
3648 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
3650 (XSETPVECTYPE): Rewrite in terms of new macro.
3651 (XSETPVECTYPESIZE): New macro, specifying both type and size.
3652 This is a bit clearer, and further avoids the possibility of
3653 undesirable aliasing.
3654 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
3655 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
3656 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
3657 since Lisp_Subr is a special case (no "next" field).
3658 (ASIZE): Now uses header.size rather than size.
3659 All previous uses of XVECTOR (foo)->size replaced to use this macro,
3660 to avoid the hassle of writing XVECTOR (foo)->header.size.
3661 (struct vectorlike_header): New type.
3662 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
3663 object, to help avoid aliasing.
3664 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
3665 (SUBRP): Likewise, since Lisp_Subr is a special case.
3666 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
3667 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
3668 (struct Lisp_Hash_Table): Combine first two members into a single
3669 struct vectorlike_header member. All uses of "size" and "next" members
3670 changed to be "header.size" and "header.next".
3671 * buffer.h (struct buffer): Likewise.
3672 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
3673 * frame.h (struct frame): Likewise.
3674 * process.h (struct Lisp_Process): Likewise.
3675 * termhooks.h (struct terminal): Likewise.
3676 * window.c (struct save_window_data, struct saved_window): Likewise.
3677 * window.h (struct window): Likewise.
3678 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
3679 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
3680 * buffer.c (init_buffer_once): Likewise.
3681 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
3683 * process.c (Fformat_network_address): Use local var for size,
3686 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
3688 Make the Lisp reader and string-to-float more consistent (Bug#8525)
3689 * data.c (atof): Remove decl; no longer used or needed.
3690 (digit_to_number): Move to lread.c.
3691 (Fstring_to_number): Use new string_to_number function, to be
3692 consistent with how the Lisp reader treats infinities and NaNs.
3693 Do not assume that floating-point numbers represent EMACS_INT
3694 without losing information; this is not true on most 64-bit hosts.
3695 Avoid double-rounding errors, by insisting on integers when
3696 parsing non-base-10 numbers, as the documentation specifies.
3697 * lisp.h (string_to_number): New decl, replacing ...
3698 (isfloat_string): Remove.
3699 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
3700 (read1): Do not accept +. and -. as integers; this
3701 appears to have been a coding error. Similarly, do not accept
3702 strings like +-1e0 as floating point numbers. Do not report
3703 overflow for integer overflows unless the base is not 10 which
3704 means we have no simple and reliable way to continue.
3705 Break out the floating-point parsing into a new
3706 function string_to_number, so that Fstring_to_number parses
3707 floating point numbers consistently with the Lisp reader.
3708 (digit_to_number): Move here from data.c. Make it static inline.
3709 (E_CHAR, EXP_INT): Remove, replacing with ...
3710 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
3711 (string_to_number): New function, replacing isfloat_string.
3712 This function checks for valid syntax and produces the resulting
3713 Lisp float number too. Rework it so that string-to-number
3714 no longer mishandles examples like "1.0e+". Use strtoumax,
3715 so that overflow for non-base-10 numbers is reported only when
3716 there's no portable and simple way to convert to floating point.
3718 * textprop.c (set_text_properties_1): Rewrite for clarity,
3719 and to avoid GCC warning about integer overflow.
3721 * intervals.h (struct interval): Use EMACS_INT for members
3722 where EMACS_UINT might cause problems. See
3723 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
3724 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
3725 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
3727 (offset_intervals): Tell GCC not to worry about length overflow
3728 when negating a negative length.
3730 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
3731 (overrun_check_free): Likewise.
3733 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
3734 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
3737 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3738 (gnutls_make_error): Rename local to avoid shadowing.
3739 (gnutls_emacs_global_deinit): ifdef out; not used.
3740 (Fgnutls_boot): Use const for pointer to readonly storage.
3741 Comment out unused local. Fix pointer signedness problems.
3743 * lread.c (openp): Don't stuff size_t into an 'int'.
3744 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
3745 about possible signed overflow.
3747 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3748 (GDK_KEY_g): Don't define if already defined.
3749 (xg_prepare_tooltip): Avoid pointer signedness problem.
3750 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
3752 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
3753 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
3755 * xfns.c (Fx_window_property): Simplify a bit,
3756 to make a bit faster and to avoid GCC 4.6.0 warning.
3757 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
3759 * fns.c (internal_equal): Don't assume size_t fits in int.
3761 * alloc.c (compact_small_strings): Tighten assertion a little.
3763 Replace pEd with more-general pI, and fix some printf arg casts.
3764 * lisp.h (pI): New macro, generalizing old pEd macro to other
3765 conversion specifiers. For example, use "...%"pI"d..." rather
3766 than "...%"pEd"...".
3767 (pEd): Remove. All uses replaced with similar uses of pI.
3768 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
3769 * alloc.c (check_pure_size): Don't overflow by converting size to int.
3770 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
3771 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
3772 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
3773 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
3774 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
3776 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
3777 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
3778 * print.c (safe_debug_print, print_object): Likewise.
3779 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
3781 Use pI instead of if-then-else-abort. Use %p to avoid casts,
3782 avoiding the 0 flag, which is not portable.
3783 * process.c (Fmake_network_process): Use pI to avoid cast.
3784 * region-cache.c (pp_cache): Likewise.
3785 * xdisp.c (decode_mode_spec): Likewise.
3786 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
3787 behavior on 64-bit hosts with printf arg.
3788 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
3789 (x_stop_queuing_selection_requests): Likewise.
3790 (x_get_window_property): Don't truncate byte count to an 'int'
3793 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
3794 here, since it parses constructs like leading '-' and spaces,
3795 which are not wanted; and it overflows with large numbers.
3796 Instead, simply match F[0-9]+, which is what is wanted anyway.
3798 * alloc.c: Remove unportable assumptions about struct layout.
3799 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
3800 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
3801 (allocate_vectorlike, make_pure_vector): Use the new macros,
3802 plus offsetof, to remove unportable assumptions about struct layout.
3803 These assumptions hold on all porting targets that I know of, but
3804 they are not guaranteed, they're easy to remove, and removing them
3805 makes further changes easier.
3807 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
3808 This doesn't fix a bug but makes the code clearer.
3809 (string_overrun_cookie): Now const. Use initializers that
3810 don't formally overflow signed char, to avoid warnings.
3811 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
3812 can cause Emacs to crash when string overrun checking is enabled.
3813 (allocate_buffer): Don't assume sizeof (struct buffer) is a
3814 multiple of sizeof (EMACS_INT); it need not be, if
3815 alignof(EMACS_INT) < sizeof (EMACS_INT).
3816 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
3818 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
3820 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
3822 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>

3838 * alloc.c (check_sblock, check_string_bytes)
3839 (check_string_free_list): Convert to standard C.
3841 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
3843 * w32.c (emacs_gnutls_push): Fix typo.
3845 2011-04-25 Eli Zaretskii <eliz@gnu.org>
3847 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
3848 "cast to pointer from integer of different size".
3850 Improve doprnt and its use in verror. (Bug#8545)
3851 * doprnt.c (doprnt): Document the set of format control sequences
3852 supported by the function. Use SAFE_ALLOCA instead of always
3855 * eval.c (verror): Don't limit the buffer size at size_max-1, that
3856 is one byte too soon. Don't use xrealloc; instead xfree and
3859 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
3861 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
3864 * gnutls.c: Renamed global_initialized to
3865 gnutls_global_initialized. Added internals for the
3866 :verify-hostname-error, :verify-error, and :verify-flags
3867 parameters of `gnutls-boot' and documented those parameters in the
3868 docstring. Start callback support.
3869 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
3870 unless a fatal error occurred. Call gnutls_alert_send_appropriate
3871 on error. Return error code.
3872 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
3873 (emacs_gnutls_read): Likewise.
3874 (Fgnutls_boot): Return handshake error code.

3943 * doprnt.c: Include limits.h.
3944 (SIZE_MAX): New macro.
3945 (doprnt): Return a size_t value. 2nd arg is now size_t.
3946 Many local variables are now size_t instead of int or unsigned.
3947 Improve overflow protection. Support `l' modifier for integer
3948 conversions. Support %l conversion. Don't assume an EMACS_INT
3949 argument for integer conversions and for %c.
3951 * lisp.h (doprnt): Restore prototype.
3953 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
3956 * Makefile.in (base_obj): Add back doprnt.o.
3958 * deps.mk (doprnt.o): Add back prerequisites.
3959 (callint.o): Depend on character.h.
3961 * eval.c (internal_lisp_condition_case): Include the handler
3962 representation in the error message.
3963 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
3964 when breaking from the loop.
3966 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
3968 * callint.c (Fcall_interactively): When displaying error message
3969 about invalid control letter, pass the character's codepoint, not
3970 a pointer to its multibyte form. Improve display of the character
3971 in octal and display also its hex code.
3973 * character.c (char_string): Use %x to display the (unsigned)
3974 codepoint of an invalid character, to avoid displaying a bogus
3977 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
3978 `error', not SYMBOL_NAME itself.

3986 argument to `error'.
3988 2011-04-23 Eli Zaretskii <eliz@gnu.org>
3990 * s/ms-w32.h (localtime): Redirect to sys_localtime.

4067 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
4068 so that we aren't warned about unused symbols.
4070 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
4072 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

4079 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
4080 (x_dispatch_event): Declare static if USE_GTK, and
4081 define if USE_GTK || USE_X_TOOLKIT.
4082 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
4083 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
4084 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
4085 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
4087 * xmenu.c (menu_help_callback): Pointer type fixes.
4088 Use const pointers when pointing at readonly data. Avoid pointer

4099 * keyboard.c (make_lispy_event): Remove unused local var.
4101 * frame.c, frame.h (x_get_resource_string): Bring this back, but
4102 only if HAVE_X_WINDOWS && !USE_X_TOOLKIT.
4104 * bitmaps: Change bitmaps from unsigned char back to the X11
4105 compatible char. Avoid the old compiler warnings about
4106 out-of-range initializers by using, for example, '\xab' rather
4109 * xgselect.c (xgselect_initialize): Check vs interface
4110 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).
4112 * xmenu.c (xmenu_show): Rename parm to avoid shadowing.
4114 * xterm.c (x_create_toolkit_scroll_bar): Use const * for pointers

4175 * nsfont.m: Fixed bugs in ns_get_family and
4176 ns_descriptor_to_entity that were caused by using free to
4177 deallocate memory blocks that were allocated by xmalloc (via
4178 xstrdup). This caused Emacs to crash when compiled with
4179 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
4180 --enable-checking=xmallocoverrun). xfree is now used to
4181 deallocate these memory blocks.

4589 to see whether these functions can be called from other modules.
4590 DEFUN now defines a static function. To make the function external
4591 so that it can be used in other C modules, use the new macro DEFUE.
4592 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
4593 (Finit_image_library):
4594 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
4595 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
4596 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
4597 Remove decls, since these functions are now static.
4598 (Funintern, Fget_internal_run_time): New decls, since these functions
4599 were already external.
4601 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
4602 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

4604 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
4605 * keyboard.c, keymap.c, lread.c:
4606 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
4607 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
4608 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
4609 Mark functions with DEFUE instead of DEFUN,
4610 if they are used in other modules.
4611 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
4612 decls for now-static functions.
4613 * buffer.h (Fdelete_overlay): Remove decl.
4614 * callproc.c (Fgetenv_internal): Mark as internal.
4615 * composite.c (Fremove_list_of_text_properties): Remove decl.

4640 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
4642 * editfns.c (Fformat): Remove unreachable code.
4644 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
4646 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
4649 2011-04-13 Eli Zaretskii <eliz@gnu.org>
4651 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
4652 when at ZV. (Bug#8487)
4654 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
4656 * charset.c (Fclear_charset_maps): Use xfree instead of free.
4658 * keyboard.c (parse_tool_bar_item): Likewise.
4659 * sound.c (sound_cleanup, alsa_close): Likewise.
4660 * termcap.c (tgetent): Likewise.
4661 * xfns.c (x_default_font_parameter): Likewise.
4662 * xsettings.c (read_and_apply_settings): Likewise.
4664 * alloc.c (overrun_check_malloc, overrun_check_realloc)
4665 (overrun_check_free): Protoize.
4667 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
4669 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
4670 since callers should never pass a negative size.
4671 Change the signature to match that of plain 'read' and 'write'; see
4672 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
4673 * lisp.h: Update prototypes of emacs_write and emacs_read.
4675 2011-04-11 Eli Zaretskii <eliz@gnu.org>
4677 * xdisp.c (redisplay_window): Don't try to determine the character
4678 position of the scroll margin if the window start point w->startp
4679 is outside the buffer's accessible region. (Bug#8468)
4681 2011-04-10 Eli Zaretskii <eliz@gnu.org>
4683 Fix write-region and its subroutines for buffers > 2GB.
4684 * fileio.c (a_write, e_write): Modify declaration of arguments and
4685 local variables to support buffers larger than 2GB.
4686 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
4688 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
4689 argument, local variables, and return value.
4691 * lisp.h: Update prototypes of emacs_write and emacs_read.
4693 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
4695 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
4697 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
4699 Fix more problems found by GCC 4.6.0's static checks.
4701 * xdisp.c (vmessage): Use a better test for character truncation.
4703 * charset.c (load_charset_map): <, not <=, for optimization,
4704 and to avoid potential problems with integer overflow.
4705 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
4706 * casetab.c (set_identity, shuffle): Likewise.
4707 * editfns.c (Fformat): Likewise.
4708 * syntax.c (skip_chars): Likewise.
4710 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
4711 This also lets GCC 4.6.0 generate slightly better loop code.
4713 * callint.c (Fcall_interactively): <, not <=, for optimization.
4714 (Fcall_interactively): Count the number of arguments produced,
4715 not the number of arguments given. This is simpler and lets GCC
4716 4.6.0 generate slightly better code.
4718 * ftfont.c: Distingish more carefully between FcChar8 and char.
4719 The previous code passed unsigned char * to a functions like
4720 strlen and xstrcasecmp that expect char *, which does not
4721 conform to the C standard.
4722 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
4723 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
4724 char * when the C standard requires it.
4726 * keyboard.c (read_char): Remove unused var.
4728 * eval.c: Port to Windows vsnprintf (Bug#8435).
4730 (SIZE_MAX): Define if the headers do not.
4731 (verror): Do not give up if vsnprintf returns a negative count.
4732 Instead, grow the buffer. This ports to Windows vsnprintf, which
4733 does not conform to C99. Problem reported by Eli Zaretskii.
4734 Also, simplify the allocation scheme, by avoiding the need for
4735 calling realloc, and removing the ALLOCATED variable.
4737 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
4739 Remove invocations of doprnt, as Emacs now uses vsnprintf.
4740 But keep the doprint source code for now, as we might revamp it
4741 and use it again (Bug#8435).
4742 * lisp.h (doprnt): Remove.
4743 * Makefile.in (base_obj): Remove doprnt.o.
4744 * deps.mk (doprnt.o): Remove.
4746 error: Print 32- and 64-bit integers portably (Bug#8435).
4747 Without this change, on typical 64-bit hosts error ("...%d...", N)
4748 was used to print both 32- and 64-bit integers N, which relied on
4750 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
4752 * lisp.h (error, verror): Mark as printf-like functions.
4753 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
4754 Report overflow in size calculations when allocating printf buffer.
4755 Do not truncate output string at its first null byte.
4756 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
4757 Truncate the output at a character boundary, since vsnprintf does not
4759 * charset.c (check_iso_charset_parameter): Convert internal
4760 character to string before calling 'error', since %c now has the
4762 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
4763 overflow when computing char to be passed to 'error'. Do not
4764 pass Lisp_Object to 'error'; pass the integer instead.
4765 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
4766 formatted with plain %d.
4768 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
4770 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
4772 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
4774 * xterm.c (x_catch_errors): Remove duplicate declaration.
4776 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
4778 * xdisp.c, lisp.h (message_nolog): Remove; unused.
4780 2011-04-10 Jim Meyering <meyering@redhat.com>
4782 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
4783 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
4784 return ssize_t not "int", and use size_t as the buffer length.
4785 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
4786 * gnutls.h: Update declarations.
4787 * process.c (read_process_output): Use ssize_t, to match.
4788 (send_process): Likewise.
4790 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4792 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
4794 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4796 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
4797 Use unsigned char, to match FcChar8 type definition.
4799 * xterm.c (handle_one_xevent):
4800 * xmenu.c (create_and_show_popup_menu):
4801 * xselect.c (x_decline_selection_request)
4802 (x_reply_selection_request): Avoid type-punned deref of X events.
4804 2011-04-09 Eli Zaretskii <eliz@gnu.org>
4806 Fix some uses of `int' instead of EMACS_INT.
4807 * search.c (string_match_1, fast_string_match)
4808 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
4809 (scan_buffer, find_next_newline_no_quit)
4810 (find_before_next_newline, search_command, Freplace_match)
4811 (Fmatch_data): Make some `int' variables be EMACS_INT.
4813 * xdisp.c (display_count_lines): 3rd argument and return value now
4814 EMACS_INT. All callers changed.
4815 (pint2hrstr): Last argument is now EMACS_INT.
4817 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
4818 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
4819 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

4822 (decode_coding_ccl, decode_coding_charset)
4823 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
4824 (decode_coding_iso_2022, decode_coding_emacs_mule)
4825 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
4826 <char_offset, last_offset>: Declare EMACS_INT.
4827 (encode_coding_utf_8, encode_coding_utf_16)
4828 (encode_coding_emacs_mule, encode_invocation_designation)
4829 (encode_designation_at_bol, encode_coding_iso_2022)
4830 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
4831 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
4833 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
4834 (encode_invocation_designation): Last argument P_NCHARS is now
4836 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
4837 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
4839 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
4842 * ccl.c (Fccl_execute_on_string): Declare some variables
4845 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
4847 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).

4853 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
4855 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
4857 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
4859 * keyboard.c (read_char): Call Lisp function help-form-show,
4860 instead of using internal_with_output_to_temp_buffer.
4861 (Qhelp_form_show): New var.
4862 (syms_of_keyboard): Use DEFSYM macro.
4864 * print.c (internal_with_output_to_temp_buffer): Function deleted.
4866 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
4868 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
4870 * process.c (Flist_processes): Remove to Lisp.
4871 (list_processes_1): Delete.
4873 2011-04-06 Eli Zaretskii <eliz@gnu.org>
4875 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
4877 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
4879 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
4881 Fix more problems found by GCC 4.6.0's static checks.
4883 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
4885 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
4887 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
4889 * xdisp.c (vmessage): Mark as a printf-like function.
4891 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
4893 * sound.c (sound_warning): Don't crash if arg contains a printf format.
4895 * image.c (tiff_error_handler, tiff_warning_handler): Mark as

4898 to system-supplied API.
4900 * eval.c (Fsignal): Remove excess argument to 'fatal'.
4902 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
4903 This avoids several warnings with gcc -Wstrict-overflow.
4904 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
4905 directly, rather than having caller test rule sign. This avoids
4906 some unnecessary tests.
4907 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
4908 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
4909 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
4911 * xfont.c (xfont_text_extents): Remove var that was set but not used.
4912 (xfont_open): Avoid unnecessary tests.
4914 * composite.c (composition_gstring_put_cache): Use unsigned integer.

4923 by using the new macro.
4925 * textprop.c (set_text_properties_1): Change while to do-while,
4926 since the condition is always true at first.

4941 * syntax.c (scan_words): Remove var that was set but not used.
4942 (update_syntax_table): Use unsigned instead of int.
4944 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

4948 * print.c (print_error_message): Avoid int overflow.
4950 * font.c (font_list_entities): Redo for clarity,
4951 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
4953 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
4954 (font_score): Avoid potential overflow in diff calculation.
4956 * fns.c (substring_both): Remove var that is set but not used.
4957 (sxhash): Redo loop for clarity and to avoid wraparound warning.
4959 * eval.c (funcall_lambda): Rename local to avoid shadowing.
4961 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
4962 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
4963 can always succeed if overflow has undefined behavior.
4965 * search.c (boyer_moore, wordify): Remove vars set but not used.
4966 (wordify): Omit three unnecessary tests.
4968 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
4969 All callers changed. This avoids the need for an unused var.
4971 * casefiddle.c (casify_region): Remove var that is set but not used.
4973 * dired.c (file_name_completion): Remove var that is set but not used.
4975 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
4977 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
4978 (Finsert_file_contents): Remove unnecessary code checking fd.
4980 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
4981 Check for integer overflow on size calculations.
4983 * buffer.c (Fprevious_overlay_change): Remove var that is set
4986 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
4987 Remove vars that are set but not used.
4988 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
4989 (timer_check_2): Mark vars as initialized.
4991 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
4993 * image.c (lookup_image): Remove var that is set but not used.
4994 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
4996 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
4997 that are set but not used.
4999 * xfns.c (make_invisible_cursor): Don't return garbage
5000 if XCreateBitmapFromData fails (Bug#8410).

5003 Remove vars that are set but not used.
5005 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

5009 Remove var that is set but not used.
5010 (scroll_bar_windows_size): Now size_t, not int.
5011 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
5014 * xfaces.c (realize_named_face): Remove vars that are set but not used.
5015 (map_tty_color) [!defined MSDOS]: Likewise.
5017 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
5019 * coding.c: Remove vars that are set but not used.
5020 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
5021 All callers changed.
5022 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
5023 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
5024 (decode_coding_charset): Remove vars that are set but not used.
5026 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
5027 that is set but not used.
5029 * print.c (print_object): Remove var that is set but not used.
5031 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
5032 The gnulib version avoids calling malloc in the usual case,
5033 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
5034 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
5035 * filelock.c (current_lock_owner): Likewise.
5036 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
5037 * sysdep.c: Include allocator.h, careadlinkat.h.
5038 (emacs_no_realloc_allocator): New static constant.
5039 (emacs_readlink): New function.
5040 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
5041 ../lib/careadlinkat.h.
5043 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
5045 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
5046 first non-nil return value).
5048 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
5050 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
5051 if not defined (Bug#8403).
5053 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
5055 * xdisp.c (display_count_lines): Remove parameter `start',
5056 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5057 (get_char_face_and_encoding): Remove parameter `multibyte_p',
5058 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
5059 (fill_stretch_glyph_string): Remove parameters `row' and `area',
5060 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
5061 and thereabouts. All callers changed.
5062 (get_per_char_metric): Remove parameter `f', unused since
5063 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
5065 2011-04-02 Jim Meyering <meyering@redhat.com>
5067 do not dereference NULL upon failed strdup
5068 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
5069 (ns_get_family): Likewise.
5071 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
5073 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
5075 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
5077 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
5080 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
5082 Add lexical binding.
5084 * window.c (Ftemp_output_buffer_show): New fun.
5085 (Fsave_window_excursion):
5086 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
5088 * lread.c (lisp_file_lexically_bound_p): New function.
5089 (Fload): Bind Qlexical_binding.
5090 (readevalloop): Remove `evalfun' arg.
5091 Bind Qinternal_interpreter_environment.
5092 (Feval_buffer): Bind Qlexical_binding.
5093 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
5095 (syms_of_lread): Declare `lexical-binding'.
5097 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
5099 * keyboard.c (eval_dyn): New fun.
5100 (menu_item_eval_property): Use it.
5102 * image.c (parse_image_spec): Use Ffunctionp.
5104 * fns.c (concat, mapcar1): Accept byte-code-functions.
5106 * eval.c (Fsetq): Handle lexical vars.
5107 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
5108 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
5109 (FletX, Flet): Obey lexical binding.
5110 (Fcommandp): Handle closures.
5111 (Feval): New `lexical' arg.
5112 (eval_sub): New function extracted from Feval. Use it almost
5113 everywhere where Feval was used. Look up vars in lexical env.
5115 (Ffunctionp): Move from subr.el.
5116 (Ffuncall): Handle closures.
5117 (apply_lambda): Remove `eval_flags'.
5118 (funcall_lambda): Handle closures and new byte-code-functions.
5119 (Fspecial_variable_p): New function.
5120 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
5121 but without exporting it to Lisp.
5123 * doc.c (Fdocumentation, store_function_docstring):
5124 * data.c (Finteractive_form): Handle closures.
5126 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
5129 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
5131 (exec_byte_code): New function extracted from Fbyte_code to handle new
5132 calling convention for byte-code-functions. Add new byte-codes.
5134 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
5136 * alloc.c (Fmake_symbol): Init new `declared_special' field.
5138 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
5140 * xdisp.c (redisplay_internal): Fix prototype.
5142 2011-03-31 Eli Zaretskii <eliz@gnu.org>
5144 * xdisp.c (SCROLL_LIMIT): New macro.
5145 (try_scrolling): Use it when setting scroll_limit.
5146 Limit scrolling to 100 screen lines.
5147 (redisplay_window): Even when falling back on "recentering",
5148 position point in the window according to scroll-conservatively,
5149 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
5151 (try_scrolling): When point is above the window, allow searching
5152 as far as scroll_max, or one screenful, to compute vertical
5153 distance from PT to the scroll margin position. This prevents
5154 try_scrolling from unnecessarily failing when
5155 scroll-conservatively is set to a value slightly larger than the
5156 window height. Clean up the case of PT below the margin at bottom
5157 of window: scroll_max can no longer be INT_MAX. When aggressive
5158 scrolling is in use, don't let point enter the opposite scroll
5159 margin as result of the scroll.
5160 (syms_of_xdisp) <scroll-conservatively>: Document the
5161 threshold of 100 lines for never-recentering scrolling.
5163 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
5165 * dispextern.h (move_it_by_lines):
5166 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
5167 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
5168 (message_log_check_duplicate): Remove parameters `prev_bol' and
5169 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5170 (redisplay_internal): Remove parameter `preserve_echo_area',
5171 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
5173 * indent.c (Fvertical_motion):
5174 * window.c (window_scroll_pixel_based, Frecenter):
5175 Don't pass `need_y_p' to `move_it_by_lines'.
5177 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
5179 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
5180 steal a few bits to be more compact.
5181 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
5182 Remove unneeded casts.
5184 * bytecode.c (Fbyte_code): CAR and CDR can GC.
5186 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
5188 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
5189 binding" message (bug#7967).
5191 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
5193 Fix more problems found by GCC 4.6.0's static checks.
5195 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
5196 Remove unused local var.
5198 * editfns.c (Fmessage_box): Remove unused local var.
5200 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
5201 (note_mode_line_or_margin_highlight, note_mouse_highlight):
5202 Omit unused local vars.
5203 * window.c (shrink_windows): Omit unused local var.
5204 * menu.c (digest_single_submenu): Omit unused local var.
5205 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
5206 Omit unused local var.
5208 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
5209 Don't assume string length fits in int.
5210 (keyremap_step, read_key_sequence): Use size_t for sizes.
5211 (read_key_sequence): Don't check last_real_key_start redundantly.
5213 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
5214 instead of alloca (Bug#8344).
5216 * eval.c (Fbacktrace): Don't assume nargs fits in int.
5217 (Fbacktrace_frame): Don't assume nframes fits in int.
5219 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
5221 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
5224 * term.c (produce_glyphless_glyph): Remove unnecessary test.
5226 * cm.c (calccost): Turn while-do into do-while, for clarity.
5228 * keyboard.c (syms_of_keyboard): Use the same style as later
5229 in this function when indexing through an array. This also
5230 works around GCC bug 48267.
5232 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
5234 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
5236 * chartab.c (sub_char_table_ref_and_range): Redo for slight
5237 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
5239 * keyboard.c, keyboard.h (num_input_events): Now size_t.
5240 This avoids undefined behavior on integer overflow, and is a bit
5241 more convenient anyway since it is compared to a size_t variable.
5243 Variadic C functions now count arguments with size_t, not int.
5244 This avoids an unnecessary limitation on 64-bit machines, which
5245 caused (substring ...) to crash on large vectors (Bug#8344).
5246 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
5247 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
5248 All variadic functions and their callers changed accordingly.
5249 (struct gcpro.nvars): Now size_t, not int. All uses changed.
5250 * data.c (arith_driver, float_arith_driver): Likewise.
5251 * editfns.c (general_insert_function): Likewise.
5252 * eval.c (struct backtrace.nargs, interactive_p)
5253 (internal_condition_case_n, run_hook_with_args, apply_lambda)
5254 (funcall_lambda, mark_backtrace): Likewise.
5255 * fns.c (concat): Likewise.
5256 * frame.c (x_set_frame_parameters): Likewise.
5257 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
5258 0 if not found, not -1. All callers changed.
5260 * alloc.c (garbage_collect): Don't assume stack size fits in int.
5261 (stack_copy_size): Now size_t, not int.
5262 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
5264 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
5266 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
5267 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
5268 All callers changed.
5270 * lisp.h (multibyte_char_to_unibyte):
5271 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
5272 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
5273 * character.h (CHAR_TO_BYTE8):

5276 * keymap.c (push_key_description):
5277 * search.c (Freplace_match):
5278 * xdisp.c (message_dolog, set_message_1): All callers changed.
5280 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5282 * keyboard.c (safe_run_hook_funcall): New function.
5283 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
5284 don't set the hook to nil, but remove the offending function instead.
5285 (Qcommand_hook_internal): Remove, unused.
5286 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
5287 Vcommand_hook_internal.
5289 * eval.c (enum run_hooks_condition): Remove.
5290 (funcall_nil, funcall_not): New functions.
5291 (run_hook_with_args): Call each function through a `funcall' argument.
5292 Remove `cond' argument, now redundant.
5293 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)

5301 * print.c (strout): Remove parameter `multibyte', unused since
5302 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
5304 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
5305 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
5306 All callers changed.
5308 * w32.c (_wsa_errlist): Use braces for struct initializers.
5310 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
5311 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
5312 All callers changed.
5313 (string_buffer_position): Likewise. Also, make static (it's never
5314 used outside xdisp.c).
5315 (cursor_row_p): Remove parameter `w', unused since
5316 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

5318 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
5319 All callers changed.

5371 * w32menu.c (w32_menu_display_help):
5372 * xmenu.c (show_help_event, menu_help_callback):

5381 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
5382 (gap_left, gap_right): Don't call it.
5384 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
5386 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
5387 incurred during fontification.

5455 2011-03-23 Julien Danjou <julien@danjou.info>
5457 * term.c (Fsuspend_tty, Fresume_tty):
5458 * minibuf.c (read_minibuf, run_exit_minibuf_hook):

5467 * buffer.c (Fkill_all_local_variables):
5468 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
5470 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
5471 unconditionnaly since it does the check itself.
5473 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
5475 Fix more problems found by GCC 4.5.2's static checks.
5477 * coding.c (encode_coding_raw_text): Avoid unnecessary test
5478 the first time through the loop, since we know p0 < p1 then.
5479 This also avoids a gcc -Wstrict-overflow warning.
5481 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
5482 leading to a memory leak, possible in functions like
5483 load_charset_map_from_file that can allocate an unbounded number
5484 of objects (Bug#8318).
5486 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
5487 that could (at least in theory) be that large.
5489 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
5490 This is less likely to overflow, and avoids undefined behavior if
5491 overflow does occur. All callers changed. Use strtoul to scan
5492 for the unsigned long integer.
5493 (pint2hrstr): Simplify and tune code slightly.
5494 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
5496 * scroll.c (do_scrolling): Work around GCC bug 48228.
5497 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
5499 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
5500 This also avoids a warning with gcc -Wstrict-overflow.
5501 (validate_x_resource_name): Simplify count usage.
5502 This also avoids a warning with gcc -Wstrict-overflow.
5504 * fileio.c (Fcopy_file): Report error if fchown or fchmod
5507 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
5509 * process.c (Fmake_network_process): Use socklen_t, not int,
5510 where POSIX says socklen_t is required in portable programs.
5511 This fixes a porting bug on hosts like 64-bit HP-UX, where

5529 Include tparam.h instead, since it declares them.
5530 * cm.h (PC): Remove extern decl; tparam.h now does this.
5531 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
5532 * terminfo.c: Include tparam.h, to check interfaces.
5533 (tparm): Make 1st arg a const pointer in decl. Put it at top level.

5584 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
5586 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
5588 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
5589 clobbering (Bug#8298).
5590 * sysdep.c (sys_subshell): Likewise.
5591 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
5593 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
5594 This should get cleaned up, so that child_setup has the
5595 same signature on all platforms.
5597 * callproc.c (call_process_cleanup): Now static.
5598 (relocate_fd): Rename locals to avoid shadowing.
5600 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

5659 n rather than nn, a way that does not involve shadowing.
5660 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
5662 * deps.mk (unexalpha.o): Remove; unused.
5664 New file unexec.h, the (simple) interface for unexec (Bug#8267).
5665 * unexec.h: New file.

5687 warning when compiling print.c.
5689 * font.c (font_unparse_fcname): Abort in an "impossible" situation
5690 instead of using an uninitialized var.
5691 (font_sort_entities): Mark var as initialized.

5766 Use functions, not macros, for up- and down-casing (Bug#8254).
5767 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5768 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
5769 to use the following functions instead of these macros.
5770 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
5771 EMACS_INT, since callers assume the returned value fits in int.
5772 (upcase1): Likewise, for UPCASE_TABLE.
5773 (uppercasep, lowercasep, upcase): New static inline functions.
5774 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

5784 (regex_compile, re_match_2_internal): Mark locals as initialized.
5785 (RETALLOC_IF): Define only if needed.
5786 (WORDCHAR_P): Likewise. This one is never needed, but is used
5787 only in a comment talking about a compiler bug, so put inside
5788 the #if 0 of that comment.
5789 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
5790 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
5793 * search.c (boyer_moore): Rename locals to avoid shadowing.

5818 gcpro1, gcpro2, etc.
5819 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
5821 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
5822 argument, for consistency with GCPRO2_VAR, etc: it is now the
5823 prefix of the variable, not the variable itself. All uses
5825 * dired.c (directory_files_internal, file_name_completion):
5826 Rename locals to avoid shadowing.
5828 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
5829 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
5830 dired.c's scmp function, had undefined behavior.
5831 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5832 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
5833 * buffer.h: ... to here, because these macros use current_buffer,
5834 and the new implementation with inline functions needs to have
5835 current_buffer in scope now, rather than later when the macros
5837 (downcase, upcase1): New static inline functions.
5838 (DOWNCASE, UPCASE1): Reimplement using these functions.
5839 This avoids undefined behavior in expressions like
5840 DOWNCASE (x) == DOWNCASE (y), which previously suffered
5841 from race conditions in accessing the global variables
5842 case_temp1 and case_temp2.
5843 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
5844 * lisp.h (case_temp1, case_temp2): Remove their decls.
5845 * character.h (ASCII_CHAR_P): Move from here ...
5846 * lisp.h: ... to here, so that the inline functions mentioned
5849 * dired.c (directory_files_internal_unwind): Now static.
5851 * fileio.c (file_name_as_directory, directory_file_name):
5852 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
5854 (file_name_as_directory): Use const pointers when appropriate.
5855 (Fexpand_file_name): Likewise. In particular, newdir might
5856 point at constant storage, so make it a const pointer.
5857 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
5858 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
5860 (Fset_file_times, Finsert_file_contents, auto_save_error):

5869 * lisp.h (verify_bytepos, count_markers): New decls,
5870 so that gcc does not warn that these functions aren't declared.
5872 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
5873 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

5875 (copy_text): Remove unused local var.

5878 (lock_file_1): Rename local to avoid shadowing.
5880 * buffer.c (fix_overlays_before): Mark locals as initialized.
5881 (fix_start_end_in_overlays): Likewise. This function should be
5882 simplified by using pointers-to-pointers, but that's a different
5884 (switch_to_buffer_1): Now static.
5885 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
5886 (report_overlay_modification): Rename locals to avoid shadowing.
5888 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
5889 Fix pointer signedness issue.
5890 (sys_subshell): Mark local as volatile if checking for lint,
5891 to suppress a gcc -Wclobbered warning that does not seem to be right.
5892 (MAXPATHLEN): Define only if needed.
5894 * process.c (serial_open, serial_configure): Move decls from here ...
5895 * systty.h: ... to here, so that they can be checked.
5897 * fns.c (get_random, seed_random): Move extern decls from here ...
5898 * lisp.h: ... to here, so that they can be checked.
5900 * sysdep.c (reset_io): Now static.

5913 (echo_char, echo_dash, cmd_error, top_level_2):
5914 (poll_for_input, handle_async_input): Now static.
5915 (read_char, kbd_buffer_get_event, make_lispy_position):

5934 if GCC considers string literals to be constants.
5936 * lisp.h (fatal_error_signal): Add decl, since it's exported.
5938 * dbusbind.c: Pointer signedness fixes.
5939 (xd_signature, xd_append_arg, xd_initialize):
