102 where the system imposes an 'int' limit.
104 * frame.c: Integer overflow fixes.
105 (set_menu_bar_lines, x_set_frame_parameters, x_set_scroll_bar_width)

193 * image.c (xpm_get_color_table_h):
194 * lisp.h (hash_lookup, hash_put):
195 * minibuf.c (Ftest_completion):
196 Use ptrdiff_t for hash table indexes, not int (which is too
197 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
198 32-bit --with-wide-int hosts).
200 * charset.c (Fdefine_charset_internal): Check for integer overflow.
201 Add a FIXME comment about memory leaks.
202 (syms_of_charset): Don't assume xmalloc returns.
204 Don't assume that stated character widths fit in int.

206 * character.h (CHAR_WIDTH):
207 * indent.c (MULTIBYTE_BYTES_WIDTH):
208 Use sanitize_char_width to avoid undefined and/or bad behavior
209 with outlandish widths.
210 * character.h (sanitize_tab_width): Renamed from sanitize_width,
211 now that we have two such functions. All uses changed.
212 (sanitize_char_width): New inline function.

223 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.

229 * xterm.c: don't go over XClientMessageEvent limit
230 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
231 (x_send_scroll_bar_event): Likewise. Check that the size does not
232 exceed limits imposed by XClientMessageEvent, as well as the usual
233 ptrdiff_t and size_t limits.
235 * keyboard.c: Overflow, signedness and related fixes.
236 (make_lispy_movement): Use same integer type in forward decl
237 that is used in the definition.
238 (read_key_sequence, keyremap_step):
239 Change bufsize argument back to int, undoing my 2011-03-30 change.
240 We prefer signed types, and int is wide enough here.
241 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
242 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
243 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
244 length, not size_t. Use ptrdiff_t for index, not int.
245 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
246 possibility of integer overflow.
248 Overflow, signedness and related fixes for images.

251 (struct_it.image_id, struct image.id, struct image_cache.size)
252 (struct image_cache.used, struct image_cache.ref_count):
253 * gtkutil.c (update_frame_tool_bar):

258 * xdisp.c (calc_pixel_width_or_height):
259 * xfns.c (image_cache_refcount):

264 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
265 Omit unnecessary casts to int.
266 (parse_image_spec): Check that integers fall into 'int' range
267 when the callers expect that.
268 (image_ascent): Redo ascent calculation to avoid int overflow.
269 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
270 (lookup_image): Remove unnecessary tests.
271 (xbm_image_p): Locals are now of int, not EMACS_INT,
272 since parse_image_check makes sure they fit into int.
273 (png_load, gif_load, svg_load_image):
274 Prefer int to unsigned where either will do.
275 (tiff_handler): New function, combining the cores of the
276 old tiff_error_handler and tiff_warning_handler. This
277 function is rewritten to use vsnprintf and thereby avoid
278 stack buffer overflows. It uses only the features of vsnprintf
279 that are common to both POSIX and native Microsoft.
280 (tiff_error_handler, tiff_warning_handler): Use it.
281 (tiff_load, gif_load, imagemagick_load_image):
282 Don't assume :index value fits in 'int'.
283 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
284 (imagemagick_load_image): Check that crop parameters fit into
285 the integer types that MagickCropImage accepts. Don't assume
286 Vimagemagick_render_type has a nonnegative value. Don't assume
287 size_t fits in 'long'.
288 (gs_load): Use printmax_t to print the widest integers possible.
289 Check for integer overflow when computing image height and width.
291 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
293 Integer signedness and overflow and related fixes. (Bug#9079)
295 * bidi.c: Integer size and overflow fixes.
296 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
297 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
298 (bidi_cache_find_level_change, bidi_cache_ensure_space)
299 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
300 (bidi_find_other_level_edge):
301 Use ptrdiff_t instead of EMACS_INT where either will do.
302 This works better on 32-bit hosts configured --with-wide-int.
303 (bidi_cache_ensure_space): Check for size-calculation overflow.
304 Use % rather than repeated addition, for better worst-case speed.
305 Don't set bidi_cache_size until after xrealloc returns, because it
307 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
308 (bidi_cache_ensure_space): Also check that the bidi cache size
309 does not exceed that of the largest Lisp string or buffer. See Eli
310 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
312 * alloc.c (__malloc_size_t): Remove.
313 All uses replaced by size_t. See Andreas Schwab's note
314 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
316 * image.c: Improve checking for integer overflow.
317 (check_image_size): Assume that f is nonnull, since
318 it is always nonnull in practice. This is one less thing to
319 worry about when checking for integer overflow later.
320 (x_check_image_size): New function, which checks for integer
321 overflow issues inside X.
322 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
323 This removes the need for a memory_full check.
324 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
325 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
326 (xbm_read_bitmap_data): Change locals back to 'int', since
327 their values must fit in 'int'.
328 (xpm_load_image, png_load, tiff_load):
329 Invoke x_create_x_image_and_pixmap earlier,
330 to avoid much needless work if the image is too large.
331 (tiff_load): Treat overly large images as if
332 x_create_x_image_and_pixmap failed, not as malloc failures.
333 (gs_load): Use x_check_image_size.
335 * gtkutil.c: Omit integer casts.
336 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
337 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
339 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
341 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
342 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
343 would wrongly return t on a 64-bit host.
345 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
346 The plain *_OVERFLOW macros run afoul of GCC bug 49705
347 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
348 and therefore cause GCC to emit a bogus diagnostic in some cases.
350 * image.c: Integer signedness and overflow and related fixes.
351 This is not an exhaustive set of fixes, but it's time to
352 record what I've got.
353 (lookup_pixel_color, check_image_size): Remove redundant decls.
354 (check_image_size): Don't assume that arbitrary EMACS_INT values
355 fit in 'int', or that arbitrary 'double' values fit in 'int'.
356 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
357 (tiff_load, imagemagick_load_image):
358 Check for overflow in size calculations.
359 (x_create_x_image_and_pixmap): Remove unnecessary test for
360 xmalloc returning NULL; that can't happen.
361 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
362 (xpm_color_bucket): Use better integer hashing function.
363 (xpm_cache_color): Don't possibly over-allocate memory.
364 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
366 Use ptrdiff_t, not int or size_t, to record sizes.
367 (png_load): Don't assume values greater than 2**31 fit in 'int'.
368 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
369 either works, as we prefer signed integers.
370 (tiff_read_from_memory, tiff_write_from_memory):
371 Return tsize_t, not size_t, since that's what the TIFF API wants.
372 (tiff_read_from_memory): Don't fail simply because the read would
373 go past EOF; instead, return a short read.
374 (tiff_load): Omit no-longer-needed casts.
375 (Fimagemagick_types): Don't assume size fits into 'int'.
377 Improve hashing quality when configured --with-wide-int.
378 * fns.c (hash_string): New function, taken from sxhash_string.
379 Do not discard information about ASCII character case; this
380 discarding is no longer needed.
381 (sxhash-string): Use it. Change sig to match it. Caller changed.
382 * lisp.h: Declare it.
383 * lread.c (hash_string): Remove, since we now use fns.c's version.
384 The fns.c version returns a wider integer if --with-wide-int is
385 specified, so this should help the quality of the hashing a bit.
387 * emacs.c: Integer overflow minor fix.
388 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
389 Define only if GNU_LINUX.
390 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
392 * dispnew.c: Integer signedness and overflow fixes.
393 Remove unnecessary forward decls, that were a maintenance hassle.
394 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
396 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
397 (scrolling_window): Use ptrdiff_t, not int, for byte count.
398 (prepare_desired_row, line_draw_cost):
399 Use int, not unsigned, where either works.
400 (save_current_matrix, restore_current_matrix):
401 Use ptrdiff_t, not size_t, where either works.
402 (init_display): Check for overflow more accurately, and without
403 relying on undefined behavior.
405 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
406 Remove, replacing with the new symbols in lisp.h. All uses changed.
407 * fileio.c (make_temp_name):
408 * filelock.c (lock_file_1, lock_file):
409 * xdisp.c (message_dolog):
410 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
411 Use pMd etc. instead.
412 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
413 replacing the pWIDE etc. symbols removed from editfns.c.
415 * keyboard.h (num_input_events): Now uintmax_t.
416 This is (very slightly) less likely to mess up due to wraparound.
419 * buffer.c: Integer signedness fixes.
420 (alloc_buffer_text, enlarge_buffer_text):
421 Use ptrdiff_t rather than size_t when either will do, as we prefer
424 * alloc.c: Integer signedness and overflow fixes.
425 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
426 (__malloc_size_t): Default to size_t, not to int.
427 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
428 (Fgarbage_collect, mark_object_loop_halt, mark_object):
429 Prefer ptrdiff_t to size_t when either would do, as we prefer
431 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
432 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
433 Now const. Initialize with values that are in range even if char
435 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
436 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
437 These functions do the right thing with sizes > 2**32.
438 (check_depth): Now ptrdiff_t, not int.
439 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
440 Adjust to new way of storing sizes. Check for size overflow bugs
442 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
443 slightly wrong anyway, as it missed one instance of
444 XMALLOC_OVERRUN_CHECK_OVERHEAD.
445 (refill_memory_reserve): Omit needless cast to size_t.
446 (mark_object_loop_halt): Mark as externally visible.
448 * xselect.c: Integer signedness and overflow fixes.
449 (Fx_register_dnd_atom, x_handle_dnd_message):
450 Use ptrdiff_t, not size_t, since we prefer signed.
451 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
452 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
453 x_dnd_atoms_size and x_dnd_atoms_length.
455 * doprnt.c: Prefer signed to unsigned when either works.
459 * xdisp.c (vmessage):
460 Use ptrdiff_t, not size_t, when using or implementing doprnt,
461 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
462 prefer signed arithmetic to avoid comparison confusion.
463 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
466 Assume freestanding C89 headers, string.h, stdlib.h.
467 * data.c, doprnt.c, floatfns.c, print.c:
468 Include float.h unconditionally.
469 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
470 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
471 * regex.c: Likewise for stddef.h, string.h.
472 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
473 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
474 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
475 (STDC_HEADERS): Remove obsolete defines.
476 * sysdep.c: Include limits.h unconditionally.
478 Assume support for memcmp, memcpy, memmove, memset.
479 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
480 * regex.c (memcmp, memcpy):
481 Remove; we assume C89 now.
483 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
484 (__malloc_safe_bcopy): Remove; no longer needed.
486 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
487 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
488 well either way, and we prefer signed to unsigned.

493 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
494 and the surrounding thread.
495 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
496 rather than fgets, and retry after EINTR. Otherwise, 'emacs
497 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
499 * s/openbsd.h (BROKEN_SIGIO): Define.
500 * unexelf.c (unexec) [__OpenBSD__]:
501 Don't update the .mdebug section of the Alpha COFF symbol table.
503 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
505 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
508 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
510 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
511 This fixes some race conditions on the permissions of any newly
514 * alloc.c (valid_pointer_p): Use pipe, not open.
515 This fixes some permissions issues when debugging.
517 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
518 If fchown fails to set both uid and gid, try to set just gid,
519 as that is sometimes allowed. Adjust the file's mode to eliminate
520 setuid or setgid bits that are inappropriate if fchown fails.
522 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>

540 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
541 This works around a problem with the previous change to Fcopy_file.
542 Recent glibc declares fchown with __attribute__((warn_unused_result)),
543 and without this change, GCC might complain about discarding
544 fchown's return value.
546 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
548 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

554 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
556 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
557 it's used from the C level.
559 * process.c: Use the same condition for POLL_FOR_INPUT in both
560 keyboard.c and process.c (bug#1858).

569 * doc.c (Fsubstitute_command_keys): Revert last change.
571 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
573 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
574 quotes the next character, and doesn't affect other longer
575 sequences (bug#8935).
577 * lread.c (syms_of_lread): Clarify that is isn't only
578 `eval-buffer' and `eval-defun' that's affected by
579 `lexical-binding' (bug#8460).

589 Fix minor problems found by static checking.
590 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
591 (elsz): Now a signed constant, not a size_t var. We prefer signed
592 types to unsigned, to avoid integer comparison confusion. Without
593 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
594 "cannot optimize loop, the loop counter may overflow", a symptom
596 * indent.c (Fvertical_motion): Mark locals as initialized.
597 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
599 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
601 * search.c (Fre_search_backward): Mention `case-fold-search' in
602 all the re_search_* functions (bug#8138).
604 * keyboard.c (Fopen_dribble_file): Document when the file is

637 calculation of the object to scan. Fixes an error when using
639 (next_element_from_buffer): Don't abort when IT_CHARPOS is before

643 the iterator is before prev_stop.
644 (init_iterator): Initialize bidi_p from the default value of
645 bidi-display-reordering, not from buffer-local value. Use the
646 buffer-local value only if initializing for buffer iteration.
647 (handle_invisible_prop): Support invisible properties on strings
648 that are being bidi-reordered.
649 (set_iterator_to_next): Support bidi reordering of C strings and

688 and we are bidi-iterating, don't decrement the iterator position;
689 instead, set the first_elt flag in the bidi iterator, to produce
691 (reseat_1): Remove redundant setting of string_from_display_prop_p.
692 (push_display_prop): xassert that we are iterating a buffer.
693 (push_it, pop_it): Save and restore paragraph_embedding member.

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

1159 Random fixes. E.g., (random) never returned negative values.
1160 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
1161 subseconds part to the entropy, as that's a bit more random.
1162 Prefer signed to unsigned, since the signedness doesn't matter and
1163 in general we prefer signed. When given a limit, use a
1164 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
1165 latter isn't right if USE_2_TAGS_FOR_INTS.
1166 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
1167 not 0..VALMASK. Don't discard "excess" bits that random () returns.

1180 This is more efficient than Ffile_directory_p and avoids a minor race.
1182 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
1184 * buffer.c (Foverlay_put): Say what the return value is
1187 * fileio.c (barf_or_query_if_file_exists): Check first if the file

1190 (barf_or_query_if_file_exists): Make the "File is a directory"
1191 error be more correct.
1193 * fns.c (Frequire): Remove the mention of the .gz files, since
1194 that's installation-specific, but keep the mention of
1195 `get-load-suffixes'.
1197 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
1199 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

1210 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

1312 * eval.c (struct backtrace): Simplify and port the data structure.
1313 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
1314 signed bit field, as this assumption is not portable and it makes
1315 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
1316 "char debug_on_exit : 1" as this is not portable either; instead,
1317 use the portable "unsigned int debug_on_exit : 1". Remove unused
1318 member evalargs. Remove obsolete comments about cc bombing out.

1403 bidi_at_paragraph_end, since fast_looking_at doesn't like to be
1406 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
1408 * process.c (wait_reading_process_output): Bypass select if
1409 waiting for a cell while ignoring keyboard input, and input is
1410 pending. Suggested by Jan Djärv (Bug#8869).
1412 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
1414 Use gnulib's dup2 module instead of rolling our own.
1415 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
1417 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

1482 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
1484 Integer and buffer overflow fixes (Bug#8873).
1486 * print.c (printchar, strout): Check for string overflow.
1487 (PRINTPREPARE, printchar, strout):
1488 Don't set size unless allocation succeeds.
1490 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
1491 for sizes. Check for string overflow more accurately.
1492 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
1494 * macros.c: Integer and buffer overflow fixes.
1495 * keyboard.h (struct keyboard.kbd_macro_bufsize):
1496 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

1498 Don't increment bufsize until after realloc succeeds.
1499 Check for size-calculation overflow.
1500 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
1502 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
1504 * lread.c: Integer overflow fixes.
1505 (read_integer): Radix is now EMACS_INT, not int,
1506 to improve quality of diagnostics for out-of-range radices.
1507 Calculate buffer size correctly for out-of-range radices.
1508 (read1): Check for integer overflow in radices, and in
1509 read-circle numbers.
1510 (read_escape): Avoid int overflow.
1511 (Fload, openp, read_buffer_size, read1)
1512 (substitute_object_recurse, read_vector, read_list, map_obarray):
1513 Use ptrdiff_t, not int, for sizes.

1522 Now ptrdiff_t, not int.
1523 (read1): Don't assume doc string length fits in int. Check for
1524 out-of-range doc string lengths.
1525 (read_list): Don't assume file position fits in int.
1526 (read_escape): Check for hex character overflow.
1528 2011-06-22 Leo Liu <sdl.web@gmail.com>
1530 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
1531 Move to minibuffer.el.
1533 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
1535 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
1536 The following patches are for when GLYPH_DEBUG && !XASSERT.
1537 * dispextern.h (trace_redisplay_p, dump_glyph_string):
1538 * dispnew.c (flush_stdout):
1539 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
1540 Mark as externally visible.
1541 * dispnew.c (check_window_matrix_pointers): Now static.
1542 * dispnew.c (window_to_frame_vpos):
1543 * xfns.c (unwind_create_frame):
1544 * xterm.c (x_check_font): Remove unused local.
1545 * scroll.c (CHECK_BOUNDS):
1546 * xfaces.c (cache_fache): Rename local to avoid shadowing.
1547 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
1548 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
1549 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
1550 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
1552 (debug_method_add): Use va_list and vsprintf rather than relying
1553 on undefined behavior with wrong number of arguments.
1554 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
1555 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
1556 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
1557 since we're not interested in debugging glyphs with old libraries.
1558 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
1559 GCC 4.6.0's static checking.
1561 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
1563 Integer overflow and signedness fixes (Bug#8873).
1564 A few related buffer overrun fixes, too.

1572 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
1573 (x_create_bitmap_from_xpm_data):
1574 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
1575 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
1577 * xfaces.c (load_pixmap):
1578 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
1579 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
1580 (.bitmaps_last, struct x_output.icon_bitmap):
1581 Use ptrdiff_t, not int, for bitmap indexes.
1582 (x_allocate_bitmap_record): Check for size overflow.
1583 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
1585 Use ptrdiff_t, not int, for overlay counts.
1586 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
1587 * editfns.c (overlays_around, get_pos_property):
1588 * textprop.c (get_char_property_and_overlay):
1589 * xdisp.c (next_overlay_change, note_mouse_highlight):
1590 * xfaces.c (face_at_buffer_position):
1591 * buffer.c (OVERLAY_COUNT_MAX): New macro.
1592 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
1593 (Fnext_overlay_change, Fprevious_overlay_change)
1594 (mouse_face_overlay_overlaps, Foverlays_in):
1595 Use ptrdiff_t, not int, for sizes.
1596 (overlays_at, overlays_in): Check for size-calculation overflow.
1598 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
1600 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
1601 (x_session_initialize): Do not assume string length fits in int.
1603 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
1604 This is unlikely, but can occur if DPI is outlandish.
1606 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
1607 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
1609 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
1610 * xrdb.c (magic_file_p, search_magic_path):
1611 Omit last arg SUFFIX; it was always 0. All callers changed.
1612 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
1614 * xfont.c (xfont_match): Avoid need for strlen.
1616 * xfns.c: Don't assume strlen fits in int.
1617 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
1619 * xdisp.c (message_log_check_duplicate): Return intmax_t,
1620 not unsigned long, as we prefer signed integers. All callers changed.
1621 Detect integer overflow in repeat count.
1622 (message_dolog): Don't assume print length fits in 39 bytes.
1623 (display_mode_element): Don't assume strlen fits in int.
1625 * termcap.c: Don't assume sizes fit in int and never overflow.
1626 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
1627 (gobble_line): Check for size-calculation overflow.
1629 * minibuf.c (Fread_buffer):
1630 * lread.c (intern, intern_c_string):
1631 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
1632 Don't assume string length fits in int.
1634 * keyboard.c (parse_tool_bar_item):
1635 * gtkutil.c (style_changed_cb): Avoid need for strlen.
1637 * font.c: Don't assume string length fits in int.
1638 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
1639 Use ptrdiff_t, not int.
1640 (font_intern_prop): Don't assume string length fits in int.
1641 Don't assume integer property fits in fixnum.
1642 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
1644 * filelock.c: Fix some buffer overrun and integer overflow issues.
1645 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
1646 Reformulate so as not to need the command string.
1647 Invoke gzip -cd rather than gunzip, as it's more portable.
1648 (lock_info_type, lock_file_1, lock_file):
1649 Don't assume pid_t and time_t fit in unsigned long.
1650 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
1651 (current_lock_owner): Prefer signed type for sizes.
1652 Use memcpy, not strncpy, where memcpy is what is really wanted.
1653 Don't assume (via atoi) that time_t and pid_t fit in int.
1654 Check for time_t and/or pid_t out of range, e.g., via a network share.
1655 Don't alloca where an auto var works fine.
1657 * fileio.c: Fix some integer overflow issues.
1658 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
1659 Don't assume string length fits in int.
1660 (directory_file_name): Don't assume string length fits in long.
1661 (make_temp_name): Don't assume pid fits in int, or that its print
1662 length is less than 20.
1664 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
1666 * coding.c (make_subsidiaries): Don't assume string length fits in int.
1668 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
1670 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
1671 We prefer signed integers, even for size calculations.
1673 * emacs.c: Don't assume string length fits in 'int'.
1674 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
1675 (main): Don't invoke strlen when not needed.
1677 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
1678 (XD_DEBUG_MESSAGE): Don't waste a byte.
1680 * callproc.c (getenv_internal_1, getenv_internal)
1682 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
1684 * lread.c (invalid_syntax): Omit length argument.
1685 All uses changed. This doesn't fix a bug, but it simplifies the
1686 code away from its former Hollerith-constant appearance, and it's
1687 one less 'int' to worry about when looking at integer-overflow issues.
1688 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
1690 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
1691 This didn't break anything, but it didn't help either.
1692 It's confusing to put a bogus integer in a place where the actual
1693 value does not matter.
1694 (LIST_END_P): Remove unused macro and its bogus comment.
1695 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
1697 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
1698 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
1700 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
1701 We prefer signed types, and the value cannot exceed the EMACS_INT
1702 range anyway (because otherwise the length would not be representable).
1703 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
1704 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
1705 This avoids a GCC warning when WIDE_EMACS_INT.
1707 * indent.c (sane_tab_width): New function.
1708 (current_column, scan_for_column, Findent_to, position_indentation)
1709 (compute_motion): Use it. This is just for clarity.
1710 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
1712 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
1714 * lisp.h (lint_assume): New macro.
1715 * composite.c (composition_gstring_put_cache):
1716 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
1718 * editfns.c, insdel.c:
1719 Omit unnecessary forward decls, to simplify future changes.
1721 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
1723 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
1725 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
1726 Use much-faster test for byte-length change.
1727 Don't assume string byte-length fits in 'int'.
1728 Check that character arg fits in 'int'.
1729 (mapcar1): Declare byte as byte, for clarity.
1731 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
1733 * fns.c (concat): Catch string overflow earlier.
1734 Do not rely on integer wraparound.
1736 * dispextern.h (struct it.overlay_strings_charpos)
1737 (struct it.selective): Now EMACS_INT, not int.
1738 * xdisp.c (forward_to_next_line_start)
1739 (back_to_previous_visible_line_start)
1740 (reseat_at_next_visible_line_start, next_element_from_buffer):
1741 Don't arbitrarily truncate the value of 'selective' to int.
1743 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
1745 * composite.c: Don't truncate sizes to 'int'.
1746 (composition_gstring_p, composition_reseat_it)
1747 (composition_adjust_point): Use EMACS_INT, not int.
1748 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
1749 not EMACS_UINT, for indexes.
1751 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
1753 * buffer.c: Include <verify.h>.
1754 (struct sortvec.priority, struct sortstr.priority):
1755 Now EMACS_INT, not int.
1756 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
1757 (struct sortstr.size, record_overlay_string)
1758 (struct sortstrlist.size, struct sortlist.used):
1759 Don't truncate size to int.
1760 (record_overlay_string): Check for size-calculation overflow.
1761 (init_buffer_once): Check at compile-time, not run-time.
1763 2011-06-22 Jim Meyering <meyering@redhat.com>
1765 Don't leak an XBM-image-sized buffer
1766 * image.c (xbm_load): Free the image buffer after using it.
1768 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
1771 * composite.c (find_automatic_composition): Omit needless 'return 0;'
1772 that Sun C diagnosed.
1773 * fns.c (secure_hash): Fix pointer signedness issue.
1774 * intervals.c (static_offset_intervals): New function.
1775 (offset_intervals): Use it.
1777 2011-06-21 Leo Liu <sdl.web@gmail.com>
1780 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
1783 * fns.c (secure_hash): Rename from crypto_hash_function and change
1784 the first arg to accept symbols.
1785 (Fsecure_hash): New primitive.
1786 (syms_of_fns): New symbols.
1788 2011-06-20 Deniz Dogan <deniz@dogan.se>
1790 * process.c (Fset_process_buffer): Clarify return value in
1793 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
1795 * dispnew.c (add_window_display_history): Use BVAR.
1797 * xdisp.c (debug_method_add): Use BVAR.
1798 (check_window_end, dump_glyph_matrix, dump_glyph)
1799 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
1801 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
1804 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
1805 check till after the cache is created in init_frame_faces.
1807 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
1809 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
1811 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
1813 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
1814 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
1815 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
1817 Improve buffer-overflow checking (Bug#8873).
1818 * fileio.c (Finsert_file_contents):
1819 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
1820 Remove the old (too-loose) buffer overflow checks.
1821 They weren't needed, since make_gap checks for buffer overflow.
1822 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
1823 The old code merely checked for Emacs fixnum overflow, and relied
1824 on undefined (wraparound) behavior. The new code avoids undefined
1825 behavior, and also checks for ptrdiff_t and/or size_t overflow.
1827 * editfns.c (Finsert_char): Don't dump core with very negative counts.
1828 Tune. Don't use wider integers than needed. Don't use alloca.
1829 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
1831 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
1833 * insdel.c, lisp.h (buffer_overflow): New function.
1834 (insert_from_buffer_1, replace_range, replace_range_2):
1835 * insdel.c (make_gap_larger):
1836 * editfns.c (Finsert_char):
1837 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
1839 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
1841 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
1843 Integer overflow and signedness fixes (Bug#8873).
1845 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
1846 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
1848 * fileio.c: Don't assume EMACS_INT fits in off_t.
1849 (emacs_lseek): New static function.
1850 (Finsert_file_contents, Fwrite_region): Use it.
1851 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
1853 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
1855 * fns.c: Don't overflow int when computing a list length.
1856 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
1857 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
1858 truncation on 64-bit hosts. Check for QUIT every
1859 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
1860 faster and is responsive enough.
1861 (Flength): Report an error instead of overflowing an integer.
1862 (Fsafe_length): Return a float if the value is not representable
1863 as a fixnum. This shouldn't happen except in contrived situations.
1864 (Fnthcdr, Fsort): Don't assume list length fits in int.
1865 (Fcopy_sequence): Don't assume vector length fits in int.
1867 * alloc.c: Check that resized vectors' lengths fit in fixnums.
1868 (header_size, word_size): New constants.
1869 (allocate_vectorlike): Don't check size overflow here.
1870 (allocate_vector): Check it here instead, since this is the only
1871 caller of allocate_vectorlike that could cause overflow.
1872 Check that the new vector's length is representable as a fixnum.
1874 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
1875 The previous code was bogus. For example, next_almost_prime (32)
1876 returned 39, which is undesirable as it is a multiple of 3; and
1877 next_almost_prime (24) returned 25, which is a multiple of 5 so
1878 why was the code bothering to check for multiples of 7?
1880 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
1882 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
1884 Variadic C functions now count arguments with ptrdiff_t.
1885 This partly undoes my 2011-03-30 change, which replaced int with size_t.
1886 Back then I didn't know that the Emacs coding style prefers signed int.
1887 Also, in the meantime I found a few more instances where arguments
1888 were being counted with int, which may truncate counts on 64-bit
1889 machines, or EMACS_INT, which may be unnecessarily wide.
1890 * lisp.h (struct Lisp_Subr.function.aMANY)
1891 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
1892 Arg counts are now ptrdiff_t, not size_t.
1893 All variadic functions and their callers changed accordingly.
1894 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
1895 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
1896 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
1897 * callint.c (Fcall_interactively): Check arg count for overflow,
1898 to avoid potential buffer overrun. Use signed char, not 'int',
1899 for 'varies' array, so that we needn't bother to check its size
1900 calculation for overflow.
1901 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
1902 * eval.c (apply_lambda):
1903 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
1904 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
1905 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
1907 * callint.c (Fcall_interactively): Don't use index var as event count.
1909 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
1910 * mem-limits.h (SIZE): Remove; no longer used.
1912 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
1914 Remove unnecessary casts.
1915 * xterm.c (x_term_init):
1916 * xfns.c (x_set_border_pixel):
1917 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
1918 These aren't needed now that we assume ANSI C.
1920 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
1921 It's more likely to cause problems (due to unsigned overflow)
1924 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
1926 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
1928 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
1930 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
1932 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
1934 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
1936 GLYPH_CODE_FACE returns EMACS_INT, not int.
1937 * dispextern.h (merge_faces):
1938 * xfaces.c (merge_faces):
1939 * xdisp.c (get_next_display_element, next_element_from_display_vector):
1940 Don't assume EMACS_INT fits in int.
1942 * character.h (CHAR_VALID_P): Remove unused parameter.
1943 * fontset.c, lisp.h, xdisp.c: All uses changed.
1945 * editfns.c (Ftranslate_region_internal): Omit redundant test.
1947 * fns.c (concat): Minor tuning based on overflow analysis.
1948 This doesn't fix any bugs. Use int to hold character, instead
1949 of constantly refetching from Emacs object. Use XFASTINT, not
1950 XINT, for value known to be a character. Don't bother comparing
1951 a single byte to 0400, as it's always less.
1953 * floatfns.c (Fexpt):
1954 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
1956 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
1959 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
1961 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
1962 Without this fix, on a 64-bit host (aset S 0 4294967386) would
1963 incorrectly succeed when S was a string, because 4294967386 was
1964 truncated before it was used.
1966 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
1967 Otherwise, an out-of-range integer could cause undefined behavior
1970 * composite.c: Use int, not EMACS_INT, for characters.
1971 (fill_gstring_body, composition_compute_stop_pos): Use int, not
1972 EMACS_INT, for values that are known to be in character range.
1973 This doesn't fix any bugs but is the usual style inside Emacs and
1974 may generate better code on 32-bit machines.
1976 Make sure a 64-bit char is never passed to ENCODE_CHAR.
1977 This is for reasons similar to the recent CHAR_STRING fix.
1978 * charset.c (Fencode_char): Check that character arg is actually
1979 a character. Pass an int to ENCODE_CHAR.
1980 * charset.h (ENCODE_CHAR): Verify that the character argument is no
1981 wider than 'int', as a compile-time check to prevent future regressions
1984 * character.c (char_string): Remove unnecessary casts.
1986 Make sure a 64-bit char is never passed to CHAR_STRING.
1987 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
1988 by silently ignoring the top 32 bits, allowing some values
1989 that were far too large to be valid characters.
1990 * character.h: Include <verify.h>.
1991 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
1992 arguments are no wider than unsigned, as a compile-time check
1993 to prevent future regressions in this area.
1995 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
1996 (Fsubst_char_in_region):
1998 * xdisp.c (decode_mode_spec_coding):
1999 Adjust to CHAR_STRING's new requirement.
2000 * editfns.c (Finsert_char, Fsubst_char_in_region):
2001 * fns.c (concat): Check that character args are actually
2002 characters. Without this test, these functions did the wrong
2003 thing with wildly out-of-range values on 64-bit hosts.
2005 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
2006 These casts should not be needed on 32-bit hosts, either.
2007 * keyboard.c (read_char):
2008 * lread.c (Fload): Remove casts to unsigned.
2010 * lisp.h (UNSIGNED_CMP): New macro.
2011 This fixes comparison bugs on 64-bit hosts.
2012 (ASCII_CHAR_P): Use it.
2013 * casefiddle.c (casify_object):
2014 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
2015 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
2016 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
2017 * dispextern.h (FACE_FROM_ID):
2018 * keyboard.c (read_char): Use UNSIGNED_CMP.
2020 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
2021 not to EMACS_INT, to avoid GCC warning.
2023 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
2025 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
2026 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
2027 isn't needed on 32-bit machines.
2029 * buffer.c (Fgenerate_new_buffer_name):
2030 Use EMACS_INT for count, not int.
2031 (advance_to_char_boundary): Return EMACS_INT, not int.
2033 * data.c (Qcompiled_function): Now static.
2035 * window.c (window_body_lines): Now static.
2037 * image.c (gif_load): Rename local to avoid shadowing.
2039 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
2040 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
2041 * alloc.c (make_save_value): Integer argument is now of type
2043 (mark_object): Use ptrdiff_t, not int.
2044 * lisp.h (pD): New macro.
2045 * print.c (print_object): Use it.
2047 * alloc.c: Use EMACS_INT, not int, to count objects.
2048 (total_conses, total_markers, total_symbols, total_vector_size)
2049 (total_free_conses, total_free_markers, total_free_symbols)
2050 (total_free_floats, total_floats, total_free_intervals)
2051 (total_intervals, total_strings, total_free_strings):
2052 Now EMACS_INT, not int. All uses changed.
2053 (Fgarbage_collect): Compute overall total using a double, so that
2054 integer overflow is less likely to be a problem. Check for overflow
2055 when converting back to an integer.
2056 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
2057 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
2058 These were 'int' variables that could overflow on 64-bit hosts;
2059 they were never used, so remove them instead of repairing them.
2060 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
2061 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
2062 Previously, this ceilinged at INT_MAX, but that doesn't work on
2064 (allocate_pseudovector): Don't use EMACS_INT when int would do.
2066 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
2067 (allocate_vectorlike): Check for ptrdiff_t overflow.
2068 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
2069 when a (possibly-narrower) signed value would do just as well.
2070 We prefer using signed arithmetic, to avoid comparison confusion.
2072 * alloc.c: Catch some string size overflows that we were missing.
2073 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
2074 for convenience in STRING_BYTES_MAX.
2075 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
2076 The definition here is exact; the one in lisp.h was approximate.
2077 (allocate_string_data): Check for string overflow. This catches
2078 some instances we weren't catching before. Also, it catches
2079 size_t overflow on (unusual) hosts where SIZE_MAX <= min
2080 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
2081 and ptrdiff_t and EMACS_INT are both 64 bits.
2083 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
2084 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
2085 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
2087 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
2089 * alloc.c (Fmake_string): Check for out-of-range init.
2091 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
2093 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
2095 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
2097 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
2098 xg_get_default_scrollbar_width.
2100 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
2101 (int_gtk_range_get_value): Move to the scroll bar part of the file.
2102 (style_changed_cb): Call update_theme_scrollbar_width and call
2103 x_set_scroll_bar_default_width and xg_frame_set_char_size for
2104 all frames (Bug#8505).
2105 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
2106 Call gtk_window_set_resizable if HAVE_GTK3.
2107 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
2108 and height if HAVE_GTK3 (Bug#8505).
2109 (scroll_bar_width_for_theme): New variable.
2110 (update_theme_scrollbar_width): New function.
2111 (xg_get_default_scrollbar_width): Move code to
2112 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
2113 (xg_initialize): Call update_theme_scrollbar_width.
2115 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
2117 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
2119 2011-06-12 Martin Rudalics <rudalics@gmx.at>
2121 * frame.c (make_frame): Call other_buffer_safely instead of
2124 * window.c (temp_output_buffer_show): Call display_buffer with
2125 second argument Vtemp_buffer_show_specifiers and reset latter
2126 immediately after the call.
2127 (Vtemp_buffer_show_specifiers): New variable.
2128 (auto_window_vscroll_p, next_screen_context_lines)
2129 (Vscroll_preserve_screen_position): Remove leading asterisks from
2132 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
2134 Fix minor problems found by GCC 4.6.0 static checking.
2135 * buffer.c (Qclone_number): Remove for now, as it's unused.
2136 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
2137 (record_buffer): Remove unused local.
2138 * frame.c (other_visible_frames, frame_buffer_list): Now static.
2139 (set_frame_buffer_list): Remove; unused.

2143 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
2145 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
2146 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
2147 Define only if HAVE_GPM.
2148 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
2149 (update_hints_inhibit): Remove; never set. All uses removed.
2150 * widgetprv.h (emacsFrameClassRec): Remove decl.

2154 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
2155 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
2156 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
2157 the same widths as pointers. This follows up on the 2011-05-06 patch.
2158 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
2159 * xterm.h: Likewise.
2160 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.

2174 * window.c (delete_deletable_window): Re-add.
2175 (Fset_window_configuration): Rewrite to handle dead buffers and
2176 consequently deletable windows.
2177 (window_tree, Fwindow_tree): Remove. Supply functionality in
2179 (compare_window_configurations): Simplify code.
2181 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
2183 * image.c (imagemagick_load_image): Fix type mismatch.
2184 (Fimagemagick_types): Likewise.
2186 * window.h (replace_buffer_in_windows): Declare.
2188 2011-06-11 Martin Rudalics <rudalics@gmx.at>
2190 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
2191 Qclone_number. Remove external declaration of Qdelete_window.
2192 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
2194 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer): Run
2195 Qbuffer_list_update_hook if allowed.

2197 buffer list implementation.
2198 (other_buffer_safely): New function.
2199 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
2200 calls to replace_buffer_in_windows and
2201 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook

2220 declaration of select_count.
2221 (Fnext_window, Fprevious_window): Rewrite doc-strings.
2222 (Fother_window): Move to window.el.
2223 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
2224 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
2225 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
2227 (replace_buffer_in_windows): Implement by calling
2228 Qreplace_buffer_in_windows.
2229 (replace_buffer_in_all_windows): Remove with some functionality

2232 (select_window_norecord, select_frame_norecord): Move in front
2233 of run_window_configuration_change_hook. Remove now obsolete
2235 (Fset_window_buffer): Rewrite doc-string. Call
2236 Qrecord_window_buffer.
2237 (keys_of_window): Move binding for other-window to window.el.
2239 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
2241 * dispextern.h (struct image): Replace data member, whose int_val
2242 and ptr_val fields were not used by anything, with a single

2302 (resize_frame_windows): Declare prototypes.
2304 * window.c (resize_window_apply): Make definition be "static" to
2305 match the prototype.
2307 2011-06-10 Martin Rudalics <rudalics@gmx.at>

2316 (Fdelete_window, delete_window): Remove. Window deletion is
2317 handled by window.el.
2318 (window_loop): Remove DELETE_OTHER_WINDOWS case. Replace
2319 Fdelete_window calls with calls to Qdelete_window.

2726 Without this change, the gnutls library would invoke malloc etc.
2727 directly, which causes problems on non-SYNC_INPUT hosts, and which

2730 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
2731 xfree instead of the default malloc, realloc, free.
2732 (Fgnutls_boot): No need to check for memory allocation failure,
2733 since xmalloc does that for us.

2764 Check for integer overflow with large hash tables.
2765 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):

2769 Use it instead of discarding useful hash info with large hash values.

2771 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
2772 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
2773 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
2774 Rewrite to use FIXNUM_BITS, as this simplifies things.
2775 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
2776 Adjust signatures to match updated version of code.
2777 (consing_since_gc): Now EMACS_INT, since a single hash table can
2778 use more than INT_MAX bytes.
2780 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
2782 Make it possible to build with GCC-4.6+ -O2 -flto.
2784 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
2786 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
2788 * minibuf.c (get_minibuffer, read_minibuf_unwind):
2789 Call minibuffer-inactive-mode.
2791 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
2793 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
2794 Update dependencies.
2796 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
2798 * data.c (init_data): Remove code for UTS, this system is not
2801 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
2803 Don't force ./temacs to start in terminal mode.
2805 * frame.c (make_initial_frame): Initialize faces in all cases, not
2806 only when CANNOT_DUMP is defined.
2807 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
2809 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
2811 * dispnew.c (add_window_display_history): Use const for the string
2812 pointer. Remove declaration, not needed.
2814 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
2816 Use 'inline', not 'INLINE'.
2817 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
2818 * alloc.c, fontset.c (INLINE): Remove.
2819 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
2820 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
2821 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
2822 * gmalloc.c (register_heapinfo): Use inline unconditionally.
2823 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
2825 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
2827 Make it possible to run ./temacs.
2829 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
2830 syms_of_callproc does the same thing. Remove test for
2831 "initialized", do it in the caller.
2832 * emacs.c (main): Avoid calling set_initial_environment when dumping.
2834 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
2836 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
2837 (read_minibuf): Use get_minibuffer.
2838 (syms_of_minibuf): Use DEFSYM.
2839 (Qmetadata): New var.
2840 * data.c (Qbuffer): Don't make it static.
2841 (syms_of_data): Use DEFSYM.
2843 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
2845 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
2846 (CCL_CODE_MIN): New macro.
2848 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
2850 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
2852 * eval.c (Qdebug): Now static.
2853 * lisp.h (Qdebug): Remove decl. This reverts a part of the
2854 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
2855 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
2857 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
2859 * image.c: Various fixes to ImageMagick code comments.
2860 (Fimagemagick_types): Doc fix.
2862 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
2864 Minor fixes prompted by GCC 4.6.0 warnings.
2866 * xselect.c (converted_selections, conversion_fail_tag): Now static.
2868 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
2869 (x_clipboard_manager_save_all): Move extern decl to ...
2870 * xterm.h: ... here, so that it can be checked for consistency.
2872 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
2874 * xselect.c (x_clipboard_manager_save_frame)
2875 (x_clipboard_manager_save_all): New functions.
2876 (Fx_clipboard_manager_save): Lisp function deleted.
2878 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
2879 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
2881 * xterm.h: Update prototype.
2883 2011-05-28 William Xu <william.xwl@gmail.com>
2885 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
2888 2011-05-28 Jim Meyering <meyering@redhat.com>
2890 Avoid a sign-extension bug in crypto_hash_function.
2891 * fns.c (to_uchar): Define.
2892 (crypto_hash_function): Use it to convert some newly-signed
2893 variables to unsigned, to avoid sign-extension bugs. For example,
2894 without this change, (md5 "truc") would evaluate to
2895 45723a2aff78ff4fff7fff1114760e62 rather than the expected
2896 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
2897 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
2899 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
2901 Integer overflow fixes.
2903 * dbusbind.c: Serial number integer overflow fixes.
2904 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
2905 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
2906 to hold a serial number that is too large for a fixnum.
2907 (Fdbus_method_return_internal, Fdbus_method_error_internal):
2908 Check for serial numbers out of range. Decode any serial number
2909 that was so large that it became a float. (Bug#8722)
2911 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
2912 (Fdbus_call_method, Fdbus_call_method_asynchronously):
2913 Use XFASTINT rather than XUINT when numbers are nonnegative.
2914 (xd_append_arg, Fdbus_method_return_internal):
2915 (Fdbus_method_error_internal): Likewise. Also, for unsigned
2916 arguments, check that Lisp number is nonnegative, rather than
2917 silently wrapping negative numbers around. (Bug#8722)
2918 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
2921 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
2923 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
2925 ccl: add integer overflow checks
2926 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
2927 (IN_INT_RANGE): New macros.
2928 (ccl_driver): Use them to check for integer overflow when
2929 decoding a CCL program. Many of the new checks are whether XINT (x)
2930 fits in int; it doesn't always, on 64-bit hosts. The new version
2931 doesn't catch all possible integer overflows, but it's an
2932 improvement. (Bug#8719)
2934 * alloc.c (make_event_array): Use XINT, not XUINT.
2935 There's no need for unsigned here.
2937 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
2938 This follows up to the 2011-05-06 change that substituted uintptr_t
2939 for EMACS_INT. This case wasn't caught back then.
2941 Rework Fformat to avoid integer overflow issues.
2942 * editfns.c: Include <float.h> unconditionally, as it's everywhere
2943 now (part of C89). Include <verify.h>.
2944 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
2945 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
2946 (Fformat): Avoid the prepass trying to compute sizes; it was only
2947 approximate and thus did not catch overflow reliably. Instead, walk
2948 through the format just once, formatting and computing sizes as we go,
2949 checking for integer overflow at every step, and allocating a larger
2950 buffer as needed. Keep track separately whether the format is
2951 multibyte. Keep only the most-recently calculated precision, rather
2952 than them all. Record whether each argument has been converted to
2953 string. Use EMACS_INT, not int, for byte and char and arg counts.
2954 Support field widths and precisions larger than INT_MAX. Avoid
2955 sprintf's undefined behavior with conversion specifications such as %#d
2956 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
2957 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
2958 formatting out-of-range floating point numbers with int
2961 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
2963 * data.c: Avoid integer truncation in expressions involving floats.
2964 * data.c: Include <intprops.h>.
2965 (arith_driver): When there's an integer overflow in an expression
2966 involving floating point, convert the integers to floating point
2967 so that the resulting value does not suffer from catastrophic
2968 integer truncation. For example, on a 64-bit host (* 4
2969 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
2970 Do not rely on undefined behavior after integer overflow.
2972 merge count_size_as_multibyte, parse_str_to_multibyte
2973 * character.c, character.h (count_size_as_multibyte):
2974 Rename from parse_str_to_multibyte; all uses changed.
2975 Check for integer overflow.
2976 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
2977 since it's now a duplicate of the other. This is more of
2978 a character than a buffer op, so better that it's in character.c.
2979 * fns.c, print.c: Adjust to above changes.
2981 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
2983 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
2985 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
2987 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
2988 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
2989 (x_clipboard_manager_save): Now static.
2990 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
2992 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
2993 (crypto_hash_function): Now static.
2994 Fix pointer signedness problems. Avoid unnecessary initializations.
2996 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
2998 * termhooks.h (Vselection_alist): Make it terminal-local.
3000 * terminal.c (create_terminal): Initialize it.
3002 * xselect.c: Support for clipboard managers.
3003 (Vselection_alist): Move to termhooks.h as terminal-local var.
3004 (LOCAL_SELECTION): New macro.
3005 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
3006 (symbol_to_x_atom): Remove gratuitous arg.
3007 (x_handle_selection_request, lisp_data_to_selection_data)
3008 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
3009 (x_own_selection, x_get_local_selection, x_convert_selection):
3010 New arg, specifying work frame. Use terminal-local Vselection_alist.
3011 (some_frame_on_display): Delete unused function.
3012 (Fx_own_selection_internal, Fx_get_selection_internal)
3013 (Fx_disown_selection_internal, Fx_selection_owner_p)
3014 (Fx_selection_exists_p): New optional frame arg.
3015 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
3016 (x_handle_selection_clear): Don't treat other terminals with the
3017 same keyboard specially. Use the terminal-local Vselection_alist.
3018 (x_clear_frame_selections): Use Frun_hook_with_args.
3020 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
3022 * xterm.h: Add support for those atoms.
3024 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
3026 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
3027 (converted_selections, conversion_fail_tag): New global variables.
3028 (x_selection_request_lisp_error): Free the above.
3029 (x_get_local_selection): Remove unnecessary code.
3030 (x_reply_selection_request): Args changed; handle arbitrary array
3031 of converted selections stored in converted_selections.
3032 Separate the XChangeProperty and SelectionNotify steps.
3033 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
3034 (x_convert_selection): New function.
3035 (x_handle_selection_event): Simplify.
3036 (x_get_foreign_selection): Don't ignore incoming requests while
3037 waiting for an answer; this will fail when we implement
3038 SAVE_TARGETS, and seems unnecessary anyway.
3039 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
3040 (Vx_sent_selection_functions): Doc fix.
3042 2011-05-26 Leo Liu <sdl.web@gmail.com>
3044 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
3046 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3048 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
3050 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
3051 for fringe update if it has periodic bitmap.
3052 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
3053 and fringe_bitmap_periodic_p.
3055 * fringe.c (get_fringe_bitmap_data): New function.
3056 (draw_fringe_bitmap_1, update_window_fringes): Use it.
3057 (update_window_fringes): Record periodicity of fringe bitmap in glyph
3058 row. Mark glyph row for fringe update if periodicity changed.
3060 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
3061 for fringe update unless it has periodic bitmap.
3063 2011-05-25 Kenichi Handa <handa@m17n.org>
3065 * xdisp.c (get_next_display_element): Set correct it->face_id for
3066 a static composition.
3068 2011-05-24 Leo Liu <sdl.web@gmail.com>
3071 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
3073 * fns.c (crypto_hash_function, Fsha1): New function.
3074 (Fmd5): Use crypto_hash_function.
3075 (syms_of_fns): Add Ssha1.
3077 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3079 * gnutls.c: Remove unused macros.
3080 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
3081 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
3082 Remove macros that are defined and never used.
3083 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
3085 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3087 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
3088 (Fx_get_selection_internal): Minor cleanup.
3089 (Fx_own_selection_internal): Rename arguments for consistency with
3092 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3094 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
3096 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3098 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
3100 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3102 * dispnew.c (scrolling_window): Don't exclude the case that the
3103 last enabled row in the desired matrix touches the bottom boundary.
3105 2011-05-21 Glenn Morris <rgm@gnu.org>
3107 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
3108 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
3109 and add some more files.
3111 2011-05-20 Eli Zaretskii <eliz@gnu.org>
3113 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
3114 report_file_error introduced by the change from 2011-05-07.
3116 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
3118 * systime.h (Time): Define only if emacs is defined.
3119 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
3120 where the include path doesn't have X11/X.h by default. See
3121 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
3123 2011-05-20 Kenichi Handa <handa@m17n.org>
3125 * composite.c (find_automatic_composition): Fix previous change.
3127 2011-05-20 Glenn Morris <rgm@gnu.org>
3129 * lisp.mk: New file, split from Makefile.in.
3130 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
3131 (shortlisp): Remove.
3132 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
3134 2011-05-19 Glenn Morris <rgm@gnu.org>
3136 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
3137 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
3138 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
3139 (lisp): Set the order to that of loadup.el.
3140 (shortlisp): Make it a copy of $lisp.
3141 (SOME_MACHINE_LISP): Remove.
3142 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
3143 Use just $shortlisp, not $SOME_MACHINE_LISP too.
3145 2011-05-18 Kenichi Handa <handa@m17n.org>
3147 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
3148 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
3149 (find_automatic_composition): Mostly rewrite for efficiency.
3151 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
3153 * makefile.w32-in: Update dependencies.
3155 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
3157 * menu.c: Include limits.h (fixes the MS-Windows build broken by
3158 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
3160 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
3162 Fix some integer overflow issues, such as string length overflow.
3164 * insdel.c (count_size_as_multibyte): Check for string overflow.
3166 * character.c (lisp_string_width): Check for string overflow.
3167 Use EMACS_INT, not int, for string indexes and lengths; in
3168 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
3169 the resulting string length overflows an EMACS_INT; instead,
3170 report a string overflow if no precision given. When checking for
3171 precision exhaustion, use a check that cannot possibly have
3172 integer overflow. (Bug#8675)
3173 * character.h (lisp_string_width): Adjust to new signature.
3175 * alloc.c (string_overflow): New function.
3176 (Fmake_string): Use it. This doesn't change behavior, but saves
3177 a few bytes and will simplify future changes.
3178 * character.c (string_escape_byte8): Likewise.
3179 * lisp.h (string_overflow): New decl.
3181 Fixups, following up to the user-interface timestamp change.
3182 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
3183 for UI timestamps, instead of unsigned long.
3184 * msdos.c (mouse_get_pos): Likewise.
3185 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
3186 * w32gui.h (Time): Define by including "systime.h" rather than by
3187 declaring it ourselves. (Bug#8664)
3189 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
3190 * image.c (clear_image_cache): Likewise.
3192 * term.c (term_mouse_position): Don't assume time_t wraparound.
3194 Be more systematic about user-interface timestamps.
3195 Before, the code sometimes used 'Time', sometimes 'unsigned long',
3196 and sometimes 'EMACS_UINT', to represent these timestamps.
3197 This change causes it to use 'Time' uniformly, as that's what X uses.
3198 This makes the code easier to follow, and makes it easier to catch
3199 integer overflow bugs such as Bug#8664.
3200 * frame.c (Fmouse_position, Fmouse_pixel_position):
3201 Use Time, not unsigned long, for user-interface timestamps.
3202 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
3203 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
3204 * keyboard.h (last_event_timestamp): Likewise.
3205 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
3206 * menu.h (xmenu_show): Likewise.
3207 * term.c (term_mouse_position): Likewise.
3208 * termhooks.h (struct input_event.timestamp): Likewise.
3209 (struct terminal.mouse_position_hook): Likewise.
3210 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
3211 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
3212 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
3213 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
3215 * menu.h, termhooks.h: Include "systime.h", for Time.
3217 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
3218 Don't assume that the difference between two unsigned long values
3219 can fit into an integer. At this point, we know button_down_time
3220 <= event->timestamp, so the difference must be nonnegative, so
3221 there's no need to cast the result if double-click-time is
3222 nonnegative, as it should be; check that it's nonnegative, just in
3223 case. This bug is triggered when events are more than 2**31 ms
3224 apart (about 25 days). (Bug#8664)
3226 * xselect.c (last_event_timestamp): Remove duplicate decl.
3227 (x_own_selection): Remove needless cast to unsigned long.
3229 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
3230 that always fit in int. Use a sentinel instead of a counter, to
3231 avoid a temp and to allay GCC's concerns about possible int overflow.
3232 * frame.h (struct frame): Use int for menu_bar_items_used
3233 instead of EMACS_INT, since it always fits in int.
3235 * menu.c (grow_menu_items): Check for int overflow.
3237 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
3239 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
3240 Before, the code was not consistent. These values cannot exceed
3241 2**31 - 1 so there's no need to make them unsigned.
3242 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
3243 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
3244 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
3246 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
3248 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
3249 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
3250 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
3251 presumably because the widths might not match.
3253 * window.c (size_window): Avoid needless test at loop start.
3255 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
3257 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
3259 2011-05-12 Drew Adams <drew.adams@oracle.com>
3261 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
3263 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3265 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
3266 `width' to `bar_area_x' and `bar_area_width', respectively.
3267 (x_scroll_run): Take account of fringe background extension.
3269 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
3270 Rename local vars `left' and `width' to `bar_area_x' and
3271 `bar_area_width', respectively.
3272 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
3273 background extension.
3275 2011-05-10 Jim Meyering <meyering@redhat.com>
3277 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
3279 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
3281 * image.c (Finit_image_library): Return t for built-in image types,
3282 like pbm and xbm. (Bug#8640)
3284 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
3286 * w32menu.c (set_frame_menubar): Fix submenu allocation.
3288 2011-05-07 Eli Zaretskii <eliz@gnu.org>
3290 * w32console.c (Fset_screen_color): Doc fix.
3291 (Fget_screen_color): New function.
3292 (syms_of_ntterm): Defsubr it.
3294 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
3295 unlink the temporary file if Fcall_process didn't create it in the
3297 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
3298 child process will be redirected to a file specified with `:file'.
3299 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
3300 cue to call_process_cleanup not to close that handle.
3302 2011-05-07 Ben Key <bkey76@gmail.com>
3304 * makefile.w32-in: The bootstrap-temacs rule now makes use of
3305 one of two shell specific rules, either bootstrap-temacs-CMD or
3306 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
3307 to the previous implementation of the bootstrap-temacs rule.
3308 The bootstrap-temacs-CMD rule is similar to the previous
3309 implementation of the bootstrap-temacs rule except that it
3310 makes use of the ESC_CFLAGS variable instead of the CFLAGS
3313 These changes, along with some changes to nt/configure.bat,
3314 nt/gmake.defs, and nt/nmake.defs, are required to extend my
3315 earlier fix to add support for --cflags and --ldflags options
3316 that include quotes so that it works whether make uses cmd or
3319 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
3321 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
3322 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
3324 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
3325 a string. Handle both cases.
3326 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
3327 (Fdbus_register_method): Use Qinvalid_function.
3329 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3331 * makefile.w32-in: Update dependencies.
3332 (LISP_H): Add inttypes.h and stdin.h.
3333 (PROCESS_H): Add unistd.h.
3335 2011-05-06 Eli Zaretskii <eliz@gnu.org>
3337 * lread.c: Include limits.h (fixes the MS-Windows build broken by
3338 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
3340 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
3342 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
3344 * term.c (vfatal): Remove stray call to va_end.
3345 It's not needed and the C Standard doesn't allow it here anyway.
3347 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
3348 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
3350 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
3353 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
3355 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3357 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
3359 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
3361 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
3363 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
3364 * charset.c (Fdefine_charset_internal): Don't initialize
3365 charset.code_space[15]. The value was garbage, on hosts with
3366 32-bit int (Bug#8600).
3368 * lread.c (read_integer): Be more consistent with string-to-number.
3369 Use string_to_number to do the actual conversion; this avoids
3370 rounding errors and fixes some other screwups. Without this fix,
3371 for example, #x1fffffffffffffff was misread as -2305843009213693952.
3372 (digit_to_number): Move earlier, for benefit of read_integer.
3373 Return -1 if the digit is out of range for the base, -2 if it is
3374 not a digit in any supported base. (Bug#8602)
3376 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
3378 * dispnew.c (scrolling_window): Return 1 if we scrolled,
3379 to match comment at start of function. This also removes a
3380 GCC warning about overflow in a 32+64-bit port.
3382 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
3384 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
3385 Reported by Stefan Monnier in
3386 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
3387 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3388 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
3390 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
3391 (EMACS_UINTPTR): Likewise, with uintptr_t.
3393 * lisp.h: Prefer 64-bit EMACS_INT if available.
3394 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
3395 on 32-bit hosts that have 64-bit int, so that they can access
3397 However, temporarily disable this change unless the temporary
3398 symbol WIDE_EMACS_INT is defined.
3400 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
3402 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
3403 This removes an assumption that EMACS_INT and long are the same
3404 width as pointers. The assumption is true for Emacs porting targets
3405 now, but we want to make other targets possible.
3406 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
3407 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
3408 In the rest of the code, change types of integers that hold casted
3409 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
3410 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
3411 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
3412 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
3413 No need to cast type when ORing.
3414 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
3415 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
3416 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
3417 assume EMACS_INT is the same width as char *.
3418 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
3419 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
3420 Remove no-longer-needed casts.
3421 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
3422 (xg_tool_bar_help_callback, xg_make_tool_item):
3423 Use EMACS_INTPTR to hold an integer
3424 that will be cast to void *; this can avoid a GCC warning
3425 if EMACS_INT is not the same width as void *.
3426 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
3427 * xdisp.c (display_echo_area_1, resize_mini_window_1):
3428 (current_message_1, set_message_1):
3429 Use a local to convert to proper width without a cast.
3430 * xmenu.c (dialog_selection_callback): Likewise.
3432 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
3433 Also, don't assume VALBITS / RAND_BITS is less than 5,
3434 and don't rely on undefined behavior when shifting a 1 left into
3436 * lisp.h (get_random): Change signature to match.
3438 * lread.c (hash_string): Use size_t, not int, for hash computation.
3439 Normally we prefer signed values; but hashing is special, because
3440 it's better to use unsigned division on hash table sizes so that
3441 the remainder is nonnegative. Also, size_t is the natural width
3442 for hashing into memory. The previous code used 'int', which doesn't
3443 retain enough info to hash well into very large tables.
3444 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
3446 * dbusbind.c: Don't possibly lose pointer info when converting.
3447 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3448 Use XPNTR rather than XHASH, so that the high-order bits of
3449 the pointer aren't lost when converting through void *.
3451 * eval.c (Fautoload): Don't double-shift a pointer.
3453 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
3455 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3457 * gnutls.c (DEF_GNUTLS_FN):
3458 * image.c (DEF_IMGLIB_FN): Make function pointers static.
3460 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
3462 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
3465 2011-05-05 Eli Zaretskii <eliz@gnu.org>
3467 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
3468 New version that can reserve upto 2GB of heap space.
3470 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
3472 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
3474 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
3476 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
3477 `gnutls_certificate_set_x509_key_file'.
3479 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
3481 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
3482 Update dependencies.
3484 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3486 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
3487 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
3488 Remove unused parameter `fildes'.
3489 * process.c (read_process_output, send_process): Don't pass it.
3491 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3493 Fix previous change: the library cache is defined in w32.c.
3494 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
3495 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
3497 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3499 Implement dynamic loading of GnuTLS on Windows.
3501 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
3502 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
3503 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
3506 * gnutls.c (Qgnutls_dll): Define.
3507 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
3508 (gnutls_*): Declare function pointers.
3509 (init_gnutls_functions): New function to initialize function pointers.
3510 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
3511 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
3512 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
3513 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
3514 (emacs_gnutls_write, emacs_gnutls_read)
3515 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
3516 (Fgnutls_available_p): New function.
3517 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
3518 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
3519 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
3521 * image.c: Include w32.h.
3522 (Vimage_type_cache): Delete.
3523 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
3524 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
3525 (w32_delayed_load): Move to w32.c.
3527 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
3529 * w32.c (QCloaded_from, Vlibrary_cache): Define.
3530 (w32_delayed_load): Move from image.c. When loading a library, record
3531 its filename in the :loaded-from property of the library id.
3532 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
3533 Initialize and staticpro them.
3534 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
3536 * process.c: Include lisp.h before w32.h, not after.
3537 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
3538 instead of gnutls_record_check_pending.
3540 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
3542 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
3544 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
3545 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
3548 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
3550 * xterm.c (x_set_frame_alpha): Do not set property on anything
3551 else than FRAME_X_OUTER_WINDOW (Bug#8608).
3553 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
3555 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)

3566 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
3567 (Qgnutls_bootprop_callbacks_verify): Make static.
3569 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
3571 * callproc.c: Indentation fixup.
3573 * sysdep.c (wait_for_termination_1): Make static.
3574 (wait_for_termination, interruptible_wait_for_termination):
3575 Move after wait_for_termination_1.
3577 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
3579 * sysdep.c (interruptible_wait_for_termination): New function
3580 which is like wait_for_termination, but allows keyboard
3583 * callproc.c (Fcall_process): Add (:file "file") as an option for
3585 (Fcall_process_region): Ditto.
3587 2011-04-30 Eli Zaretskii <eliz@gnu.org>
3589 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
3590 rather than `XVECTOR (FOO)->size'.
3592 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
3593 inttypes.h, as a gnulib replacement is used if it not available in
3596 2011-04-21 Eli Zaretskii <eliz@gnu.org>
3598 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
3599 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
3600 of MOST_POSITIVE_FIXNUM. (Bug#8528)
3602 * coding.c (coding_alloc_by_realloc): Error out if destination
3603 will grow beyond MOST_POSITIVE_FIXNUM.
3604 (decode_coding_emacs_mule): Abort if there isn't enough place in
3605 charbuf for the composition carryover bytes. Reserve an extra
3606 space for up to 2 characters produced in a loop.
3607 (decode_coding_iso_2022): Abort if there isn't enough place in
3608 charbuf for the composition carryover bytes.
3610 2011-04-21 Eli Zaretskii <eliz@gnu.org>
3612 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
3613 aborting when %lld or %lll format is passed.

3623 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
3625 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
3626 (SIZE_MAX): Move defn after all includes, as they might #define it.
3628 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3630 * w32.c (init_environment): Warn about defaulting HOME to C:\.
3632 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3634 * keyboard.c (Qdelayed_warnings_hook): Define.
3635 (command_loop_1): Run `delayed-warnings-hook'
3636 if Vdelayed_warnings_list is non-nil.
3637 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
3638 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
3640 2011-04-28 Eli Zaretskii <eliz@gnu.org>
3642 * doprnt.c (doprnt): Don't return value smaller than the buffer
3643 size if the message was truncated. (Bug#8545).

3658 2011-04-27 Eli Zaretskii <eliz@gnu.org>
3660 Improve `doprnt' and its usage. (Bug#8545)
3661 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
3662 `format_end'. Remove support for %l as a conversion specifier.
3663 Don't use xrealloc. Improve diagnostics when the %l size modifier
3664 is used. Update the commentary.
3666 * eval.c (verror): Simplify calculation of size_t.
3668 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
3671 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)

3676 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3678 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
3679 This makes this file independent of the recent pseudovector change.
3681 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
3683 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
3685 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
3686 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
3687 Remove unused local.
3688 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
3690 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
3691 GCC 4.6.0 optimizes based on type-based alias analysis.
3692 For example, if b is of type struct buffer * and v of type struct
3693 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
3694 != &v->size, and therefore "v->size = 1; b->size = 2; return
3695 v->size;" must therefore return 1. This assumption is incorrect
3696 for Emacs, since it type-puns struct Lisp_Vector * with many other
3697 types. To fix this problem, this patch adds a new type struct
3698 vectorlike_header that documents the constraints on layout of vectors
3699 and pseudovectors, and helps optimizing compilers not get fooled
3700 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
3701 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
3702 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
3704 (XSETPVECTYPE): Rewrite in terms of new macro.
3705 (XSETPVECTYPESIZE): New macro, specifying both type and size.
3706 This is a bit clearer, and further avoids the possibility of
3707 undesirable aliasing.
3708 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
3709 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
3710 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
3711 since Lisp_Subr is a special case (no "next" field).
3712 (ASIZE): Now uses header.size rather than size.
3713 All previous uses of XVECTOR (foo)->size replaced to use this macro,
3714 to avoid the hassle of writing XVECTOR (foo)->header.size.
3715 (struct vectorlike_header): New type.
3716 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
3717 object, to help avoid aliasing.
3718 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
3719 (SUBRP): Likewise, since Lisp_Subr is a special case.
3720 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
3721 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
3722 (struct Lisp_Hash_Table): Combine first two members into a single
3723 struct vectorlike_header member. All uses of "size" and "next" members
3724 changed to be "header.size" and "header.next".
3725 * buffer.h (struct buffer): Likewise.
3726 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
3727 * frame.h (struct frame): Likewise.
3728 * process.h (struct Lisp_Process): Likewise.
3729 * termhooks.h (struct terminal): Likewise.
3730 * window.c (struct save_window_data, struct saved_window): Likewise.
3731 * window.h (struct window): Likewise.
3732 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
3733 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
3734 * buffer.c (init_buffer_once): Likewise.
3735 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
3737 * process.c (Fformat_network_address): Use local var for size,
3740 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
3742 Make the Lisp reader and string-to-float more consistent (Bug#8525)
3743 * data.c (atof): Remove decl; no longer used or needed.
3744 (digit_to_number): Move to lread.c.
3745 (Fstring_to_number): Use new string_to_number function, to be
3746 consistent with how the Lisp reader treats infinities and NaNs.
3747 Do not assume that floating-point numbers represent EMACS_INT
3748 without losing information; this is not true on most 64-bit hosts.
3749 Avoid double-rounding errors, by insisting on integers when
3750 parsing non-base-10 numbers, as the documentation specifies.
3751 * lisp.h (string_to_number): New decl, replacing ...
3752 (isfloat_string): Remove.
3753 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
3754 (read1): Do not accept +. and -. as integers; this
3755 appears to have been a coding error. Similarly, do not accept
3756 strings like +-1e0 as floating point numbers. Do not report
3757 overflow for integer overflows unless the base is not 10 which
3758 means we have no simple and reliable way to continue.
3759 Break out the floating-point parsing into a new
3760 function string_to_number, so that Fstring_to_number parses
3761 floating point numbers consistently with the Lisp reader.
3762 (digit_to_number): Move here from data.c. Make it static inline.
3763 (E_CHAR, EXP_INT): Remove, replacing with ...
3764 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
3765 (string_to_number): New function, replacing isfloat_string.
3766 This function checks for valid syntax and produces the resulting
3767 Lisp float number too. Rework it so that string-to-number
3768 no longer mishandles examples like "1.0e+". Use strtoumax,
3769 so that overflow for non-base-10 numbers is reported only when
3770 there's no portable and simple way to convert to floating point.
3772 * textprop.c (set_text_properties_1): Rewrite for clarity,
3773 and to avoid GCC warning about integer overflow.
3775 * intervals.h (struct interval): Use EMACS_INT for members
3776 where EMACS_UINT might cause problems. See
3777 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
3778 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
3779 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
3781 (offset_intervals): Tell GCC not to worry about length overflow
3782 when negating a negative length.
3784 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
3785 (overrun_check_free): Likewise.
3787 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
3788 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
3791 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3792 (gnutls_make_error): Rename local to avoid shadowing.
3793 (gnutls_emacs_global_deinit): ifdef out; not used.
3794 (Fgnutls_boot): Use const for pointer to readonly storage.
3795 Comment out unused local. Fix pointer signedness problems.
3797 * lread.c (openp): Don't stuff size_t into an 'int'.
3798 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
3799 about possible signed overflow.
3801 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3802 (GDK_KEY_g): Don't define if already defined.
3803 (xg_prepare_tooltip): Avoid pointer signedness problem.
3804 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
3806 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
3807 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
3809 * xfns.c (Fx_window_property): Simplify a bit,
3810 to make a bit faster and to avoid GCC 4.6.0 warning.
3811 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
3813 * fns.c (internal_equal): Don't assume size_t fits in int.
3815 * alloc.c (compact_small_strings): Tighten assertion a little.
3817 Replace pEd with more-general pI, and fix some printf arg casts.
3818 * lisp.h (pI): New macro, generalizing old pEd macro to other
3819 conversion specifiers. For example, use "...%"pI"d..." rather
3820 than "...%"pEd"...".
3821 (pEd): Remove. All uses replaced with similar uses of pI.
3822 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
3823 * alloc.c (check_pure_size): Don't overflow by converting size to int.
3824 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
3825 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
3826 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
3827 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
3828 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
3830 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
3831 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
3832 * print.c (safe_debug_print, print_object): Likewise.
3833 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
3835 Use pI instead of if-then-else-abort. Use %p to avoid casts,
3836 avoiding the 0 flag, which is not portable.
3837 * process.c (Fmake_network_process): Use pI to avoid cast.
3838 * region-cache.c (pp_cache): Likewise.
3839 * xdisp.c (decode_mode_spec): Likewise.
3840 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
3841 behavior on 64-bit hosts with printf arg.
3842 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
3843 (x_stop_queuing_selection_requests): Likewise.
3844 (x_get_window_property): Don't truncate byte count to an 'int'
3847 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
3848 here, since it parses constructs like leading '-' and spaces,
3849 which are not wanted; and it overflows with large numbers.
3850 Instead, simply match F[0-9]+, which is what is wanted anyway.
3852 * alloc.c: Remove unportable assumptions about struct layout.
3853 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
3854 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
3855 (allocate_vectorlike, make_pure_vector): Use the new macros,
3856 plus offsetof, to remove unportable assumptions about struct layout.
3857 These assumptions hold on all porting targets that I know of, but
3858 they are not guaranteed, they're easy to remove, and removing them
3859 makes further changes easier.
3861 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
3862 This doesn't fix a bug but makes the code clearer.
3863 (string_overrun_cookie): Now const. Use initializers that
3864 don't formally overflow signed char, to avoid warnings.
3865 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
3866 can cause Emacs to crash when string overrun checking is enabled.
3867 (allocate_buffer): Don't assume sizeof (struct buffer) is a
3868 multiple of sizeof (EMACS_INT); it need not be, if
3869 alignof(EMACS_INT) < sizeof (EMACS_INT).
3870 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
3872 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
3874 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
3876 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
3878 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
3879 supposed to be handshaking. (Bug#8556)
3880 Reported by Paul Eggert <eggert@cs.ucla.edu>.
3882 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

3885 * eval.c (Qdebug): Restore global linkage.
3886 * keyboard.c (debug-on-event): New variable.
3887 (handle_user_signal): Break into debugger when debug-on-event
3888 matches the current signal symbol.

3892 * alloc.c (check_sblock, check_string_bytes)
3893 (check_string_free_list): Convert to standard C.
3895 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
3897 * w32.c (emacs_gnutls_push): Fix typo.
3899 2011-04-25 Eli Zaretskii <eliz@gnu.org>
3901 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
3902 "cast to pointer from integer of different size".
3904 Improve doprnt and its use in verror. (Bug#8545)
3905 * doprnt.c (doprnt): Document the set of format control sequences
3906 supported by the function. Use SAFE_ALLOCA instead of always
3909 * eval.c (verror): Don't limit the buffer size at size_max-1, that
3910 is one byte too soon. Don't use xrealloc; instead xfree and
3913 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
3915 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
3918 * gnutls.c: Renamed global_initialized to
3919 gnutls_global_initialized. Added internals for the
3920 :verify-hostname-error, :verify-error, and :verify-flags
3921 parameters of `gnutls-boot' and documented those parameters in the
3922 docstring. Start callback support.
3923 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
3924 unless a fatal error occurred. Call gnutls_alert_send_appropriate
3925 on error. Return error code.
3926 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
3927 (emacs_gnutls_read): Likewise.
3928 (Fgnutls_boot): Return handshake error code.

3997 * doprnt.c: Include limits.h.
3998 (SIZE_MAX): New macro.
3999 (doprnt): Return a size_t value. 2nd arg is now size_t.
4000 Many local variables are now size_t instead of int or unsigned.
4001 Improve overflow protection. Support `l' modifier for integer
4002 conversions. Support %l conversion. Don't assume an EMACS_INT
4003 argument for integer conversions and for %c.
4005 * lisp.h (doprnt): Restore prototype.
4007 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
4010 * Makefile.in (base_obj): Add back doprnt.o.
4012 * deps.mk (doprnt.o): Add back prerequisites.
4013 (callint.o): Depend on character.h.
4015 * eval.c (internal_lisp_condition_case): Include the handler
4016 representation in the error message.
4017 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
4018 when breaking from the loop.
4020 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
4022 * callint.c (Fcall_interactively): When displaying error message
4023 about invalid control letter, pass the character's codepoint, not
4024 a pointer to its multibyte form. Improve display of the character
4025 in octal and display also its hex code.
4027 * character.c (char_string): Use %x to display the (unsigned)
4028 codepoint of an invalid character, to avoid displaying a bogus
4031 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
4032 `error', not SYMBOL_NAME itself.

4035 character arguments to `error'.
4037 * charset.c (check_iso_charset_parameter): Fix incorrect argument
4038 to `error' in error message about FINAL_CHAR argument. Make sure
4039 FINAL_CHAR is a character, and use %c when it is passed as
4040 argument to `error'.
4042 2011-04-23 Eli Zaretskii <eliz@gnu.org>
4044 * s/ms-w32.h (localtime): Redirect to sys_localtime.

4121 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
4122 so that we aren't warned about unused symbols.

4133 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
4134 (x_dispatch_event): Declare static if USE_GTK, and
4135 define if USE_GTK || USE_X_TOOLKIT.
4136 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
4137 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
4138 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
4139 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
4141 * xmenu.c (menu_help_callback): Pointer type fixes.
4142 Use const pointers when pointing at readonly data. Avoid pointer
4144 (FALSE): Remove unused macro.

4147 * xfns.c (Fx_hide_tip): Move locals to avoid shadowing.
4149 * menu.c (push_submenu_start, push_submenu_end): Do not define unless

4229 * nsfont.m: Fixed bugs in ns_get_family and
4230 ns_descriptor_to_entity that were caused by using free to
4231 deallocate memory blocks that were allocated by xmalloc (via
4232 xstrdup). This caused Emacs to crash when compiled with
4233 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
4234 --enable-checking=xmallocoverrun). xfree is now used to
4235 deallocate these memory blocks.

4252 (emacs_read, emacs_write): Use it.
4253 * process.c (send_process): Adjust to the new signatures of
4254 emacs_write and emacs_gnutls_write. Do not attempt to store

4609 (catchlist, handlerlist, mark_backtrace):
4610 Declare only if BYTE_MARK_STACK.
4611 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
4612 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
4613 (message_enable_multibyte): Remove decl.
4614 (free_misc, interval_free_list, float_block, float_block_index):
4615 (n_float_blocks, float_free_list, cons_block, cons_block_index):
4616 (cons_free_list, last_marked_index):
4618 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
4619 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
4620 (mark_backtrace): Define only if BYTE_MARK_STACK.
4621 * xdisp.c (message_enable_multibyte): Now static.
4623 Declare Lisp_Object Q* variables to be 'static' if not exported.
4624 This makes it easier for human readers (and static analyzers)
4625 to see whether these variables are used from other modules.
4626 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
4627 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
4628 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

4631 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
4632 * xmenu.c, xselect.c:
4633 Declare Q* vars static if they are not used in other modules.
4634 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
4635 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
4636 Remove decls of unexported vars.
4637 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
4639 * lisp.h (DEFINE_FUNC): Make sname 'static'.
4641 Make Emacs functions such as Fatom 'static' by default.
4642 This makes it easier for human readers (and static analyzers)
4643 to see whether these functions can be called from other modules.
4644 DEFUN now defines a static function. To make the function external
4645 so that it can be used in other C modules, use the new macro DEFUE.
4646 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
4647 (Finit_image_library):
4648 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
4649 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
4650 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
4651 Remove decls, since these functions are now static.
4652 (Funintern, Fget_internal_run_time): New decls, since these functions
4653 were already external.
4655 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
4656 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

4660 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
4661 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
4662 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
4663 Mark functions with DEFUE instead of DEFUN,
4664 if they are used in other modules.
4665 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
4666 decls for now-static functions.
4667 * buffer.h (Fdelete_overlay): Remove decl.
4668 * callproc.c (Fgetenv_internal): Mark as internal.

4680 (Fremove_list_of_text_properties): Remove decls.
4681 * keyboard.c (Fthis_command_keys): Remove decl.
4682 (Fcommand_execute): New forward static decl.
4683 * keymap.c (Flookup_key): New forward static decl.
4684 (Fcopy_keymap): Now static.
4685 * keymap.h (Flookup_key): Remove decl.
4686 * process.c (Fget_process): New forward static decl.
4687 (Fprocess_datagram_address): Mark as internal.

4698 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
4700 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
4703 2011-04-13 Eli Zaretskii <eliz@gnu.org>
4705 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
4706 when at ZV. (Bug#8487)
4708 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
4710 * charset.c (Fclear_charset_maps): Use xfree instead of free.
4712 * keyboard.c (parse_tool_bar_item): Likewise.
4713 * sound.c (sound_cleanup, alsa_close): Likewise.
4714 * termcap.c (tgetent): Likewise.
4715 * xfns.c (x_default_font_parameter): Likewise.
4716 * xsettings.c (read_and_apply_settings): Likewise.
4718 * alloc.c (overrun_check_malloc, overrun_check_realloc)
4719 (overrun_check_free): Protoize.
4721 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
4723 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
4724 since callers should never pass a negative size.
4725 Change the signature to match that of plain 'read' and 'write'; see
4726 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
4727 * lisp.h: Update prototypes of emacs_write and emacs_read.
4729 2011-04-11 Eli Zaretskii <eliz@gnu.org>
4731 * xdisp.c (redisplay_window): Don't try to determine the character
4732 position of the scroll margin if the window start point w->startp
4733 is outside the buffer's accessible region. (Bug#8468)
4735 2011-04-10 Eli Zaretskii <eliz@gnu.org>
4737 Fix write-region and its subroutines for buffers > 2GB.
4738 * fileio.c (a_write, e_write): Modify declaration of arguments and
4739 local variables to support buffers larger than 2GB.
4740 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
4742 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
4743 argument, local variables, and return value.
4745 * lisp.h: Update prototypes of emacs_write and emacs_read.
4747 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
4749 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
4751 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
4753 Fix more problems found by GCC 4.6.0's static checks.
4755 * xdisp.c (vmessage): Use a better test for character truncation.
4757 * charset.c (load_charset_map): <, not <=, for optimization,
4758 and to avoid potential problems with integer overflow.
4759 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
4760 * casetab.c (set_identity, shuffle): Likewise.
4761 * editfns.c (Fformat): Likewise.
4762 * syntax.c (skip_chars): Likewise.
4764 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
4765 This also lets GCC 4.6.0 generate slightly better loop code.
4767 * callint.c (Fcall_interactively): <, not <=, for optimization.
4768 (Fcall_interactively): Count the number of arguments produced,
4769 not the number of arguments given. This is simpler and lets GCC
4770 4.6.0 generate slightly better code.
4772 * ftfont.c: Distingish more carefully between FcChar8 and char.
4773 The previous code passed unsigned char * to a functions like
4774 strlen and xstrcasecmp that expect char *, which does not
4775 conform to the C standard.
4776 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
4777 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
4778 char * when the C standard requires it.
4780 * keyboard.c (read_char): Remove unused var.
4782 * eval.c: Port to Windows vsnprintf (Bug#8435).
4784 (SIZE_MAX): Define if the headers do not.
4785 (verror): Do not give up if vsnprintf returns a negative count.
4786 Instead, grow the buffer. This ports to Windows vsnprintf, which
4787 does not conform to C99. Problem reported by Eli Zaretskii.
4788 Also, simplify the allocation scheme, by avoiding the need for
4789 calling realloc, and removing the ALLOCATED variable.
4791 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
4793 Remove invocations of doprnt, as Emacs now uses vsnprintf.
4794 But keep the doprint source code for now, as we might revamp it
4795 and use it again (Bug#8435).
4796 * lisp.h (doprnt): Remove.
4797 * Makefile.in (base_obj): Remove doprnt.o.
4798 * deps.mk (doprnt.o): Remove.
4800 error: Print 32- and 64-bit integers portably (Bug#8435).
4801 Without this change, on typical 64-bit hosts error ("...%d...", N)
4802 was used to print both 32- and 64-bit integers N, which relied on
4804 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
4806 * lisp.h (error, verror): Mark as printf-like functions.
4807 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
4808 Report overflow in size calculations when allocating printf buffer.
4809 Do not truncate output string at its first null byte.
4810 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
4811 Truncate the output at a character boundary, since vsnprintf does not
4813 * charset.c (check_iso_charset_parameter): Convert internal
4814 character to string before calling 'error', since %c now has the
4816 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
4817 overflow when computing char to be passed to 'error'. Do not
4818 pass Lisp_Object to 'error'; pass the integer instead.
4819 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
4820 formatted with plain %d.
4822 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
4824 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
4826 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
4828 * xterm.c (x_catch_errors): Remove duplicate declaration.
4830 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
4832 * xdisp.c, lisp.h (message_nolog): Remove; unused.
4834 2011-04-10 Jim Meyering <meyering@redhat.com>
4836 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
4837 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
4838 return ssize_t not "int", and use size_t as the buffer length.
4839 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
4840 * gnutls.h: Update declarations.
4841 * process.c (read_process_output): Use ssize_t, to match.
4842 (send_process): Likewise.
4844 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4846 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
4848 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4850 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
4851 Use unsigned char, to match FcChar8 type definition.
4853 * xterm.c (handle_one_xevent):
4854 * xmenu.c (create_and_show_popup_menu):
4855 * xselect.c (x_decline_selection_request)
4856 (x_reply_selection_request): Avoid type-punned deref of X events.
4858 2011-04-09 Eli Zaretskii <eliz@gnu.org>
4860 Fix some uses of `int' instead of EMACS_INT.
4861 * search.c (string_match_1, fast_string_match)
4862 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
4863 (scan_buffer, find_next_newline_no_quit)
4864 (find_before_next_newline, search_command, Freplace_match)
4865 (Fmatch_data): Make some `int' variables be EMACS_INT.
4867 * xdisp.c (display_count_lines): 3rd argument and return value now
4868 EMACS_INT. All callers changed.
4869 (pint2hrstr): Last argument is now EMACS_INT.
4871 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
4872 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
4873 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
4874 (decode_coding_utf_16, decode_coding_emacs_mule)
4875 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
4876 (decode_coding_ccl, decode_coding_charset)
4877 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
4878 (decode_coding_iso_2022, decode_coding_emacs_mule)
4879 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
4880 <char_offset, last_offset>: Declare EMACS_INT.
4881 (encode_coding_utf_8, encode_coding_utf_16)
4882 (encode_coding_emacs_mule, encode_invocation_designation)
4883 (encode_designation_at_bol, encode_coding_iso_2022)
4884 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
4885 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
4887 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
4888 (encode_invocation_designation): Last argument P_NCHARS is now
4890 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
4891 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
4893 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
4896 * ccl.c (Fccl_execute_on_string): Declare some variables
4899 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

4911 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
4913 * keyboard.c (read_char): Call Lisp function help-form-show,
4914 instead of using internal_with_output_to_temp_buffer.
4915 (Qhelp_form_show): New var.
4916 (syms_of_keyboard): Use DEFSYM macro.
4918 * print.c (internal_with_output_to_temp_buffer): Function deleted.
4920 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
4922 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
4924 * process.c (Flist_processes): Remove to Lisp.
4925 (list_processes_1): Delete.

4931 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
4933 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
4935 Fix more problems found by GCC 4.6.0's static checks.
4937 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
4939 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
4941 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
4943 * xdisp.c (vmessage): Mark as a printf-like function.
4945 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
4947 * sound.c (sound_warning): Don't crash if arg contains a printf format.
4949 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
4950 printf-like functions.
4951 (tiff_load): Add casts to remove these marks before passing them
4952 to system-supplied API.
4954 * eval.c (Fsignal): Remove excess argument to 'fatal'.
4956 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
4957 This avoids several warnings with gcc -Wstrict-overflow.
4958 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
4959 directly, rather than having caller test rule sign. This avoids
4960 some unnecessary tests.
4961 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
4962 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
4963 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

4966 (xfont_open): Avoid unnecessary tests.
4968 * composite.c (composition_gstring_put_cache): Use unsigned integer.

4971 Use EMACS_INT, not int, for length.
4973 * composite.h (COMPOSITION_DECODE_REFS): New macro,
4974 breaking out part of COMPOSITION_DECODE_RULE.
4975 (COMPOSITION_DECODE_RULE): Use it.
4976 * composite.c (get_composition_id): Remove unused local vars,
4977 by using the new macro.
4979 * textprop.c (set_text_properties_1): Change while to do-while,
4980 since the condition is always true at first.
4982 * intervals.c (graft_intervals_into_buffer): Mark var as used.
4983 (interval_deletion_adjustment): Return unsigned value.
4986 * process.c (list_processes_1, create_pty, read_process_output):

4995 * syntax.c (scan_words): Remove var that was set but not used.
4996 (update_syntax_table): Use unsigned instead of int.
4998 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

5000 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
5002 * print.c (print_error_message): Avoid int overflow.
5004 * font.c (font_list_entities): Redo for clarity,
5005 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
5007 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
5008 (font_score): Avoid potential overflow in diff calculation.
5010 * fns.c (substring_both): Remove var that is set but not used.
5011 (sxhash): Redo loop for clarity and to avoid wraparound warning.
5013 * eval.c (funcall_lambda): Rename local to avoid shadowing.
5015 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
5016 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
5017 can always succeed if overflow has undefined behavior.
5019 * search.c (boyer_moore, wordify): Remove vars set but not used.
5020 (wordify): Omit three unnecessary tests.
5022 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
5023 All callers changed. This avoids the need for an unused var.
5025 * casefiddle.c (casify_region): Remove var that is set but not used.
5027 * dired.c (file_name_completion): Remove var that is set but not used.
5029 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
5031 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
5032 (Finsert_file_contents): Remove unnecessary code checking fd.
5034 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
5035 Check for integer overflow on size calculations.
5037 * buffer.c (Fprevious_overlay_change): Remove var that is set
5040 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
5041 Remove vars that are set but not used.
5042 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
5043 (timer_check_2): Mark vars as initialized.
5045 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
5047 * image.c (lookup_image): Remove var that is set but not used.
5048 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
5050 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
5051 that are set but not used.
5053 * xfns.c (make_invisible_cursor): Don't return garbage
5054 if XCreateBitmapFromData fails (Bug#8410).
5056 * xselect.c (x_get_local_selection, x_handle_property_notify):
5057 Remove vars that are set but not used.
5059 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

5081 that is set but not used.
5083 * print.c (print_object): Remove var that is set but not used.
5085 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
5086 The gnulib version avoids calling malloc in the usual case,
5087 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
5088 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
5089 * filelock.c (current_lock_owner): Likewise.
5090 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

5114 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
5115 and thereabouts. All callers changed.
5116 (get_per_char_metric): Remove parameter `f', unused since
5117 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

5129 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
5131 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
5134 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
5136 Add lexical binding.
5138 * window.c (Ftemp_output_buffer_show): New fun.
5139 (Fsave_window_excursion):

5142 * lread.c (lisp_file_lexically_bound_p): New function.
5143 (Fload): Bind Qlexical_binding.
5144 (readevalloop): Remove `evalfun' arg.
5145 Bind Qinternal_interpreter_environment.
5146 (Feval_buffer): Bind Qlexical_binding.
5147 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
5149 (syms_of_lread): Declare `lexical-binding'.
5151 * lisp.h (struct Lisp_Symbol): New field `declared_special'.

5154 (menu_item_eval_property): Use it.
5156 * image.c (parse_image_spec): Use Ffunctionp.
5158 * fns.c (concat, mapcar1): Accept byte-code-functions.
5160 * eval.c (Fsetq): Handle lexical vars.
5161 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
5162 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
5163 (FletX, Flet): Obey lexical binding.
5164 (Fcommandp): Handle closures.
5165 (Feval): New `lexical' arg.
5166 (eval_sub): New function extracted from Feval. Use it almost
5167 everywhere where Feval was used. Look up vars in lexical env.
5169 (Ffunctionp): Move from subr.el.
5170 (Ffuncall): Handle closures.
5171 (apply_lambda): Remove `eval_flags'.
5172 (funcall_lambda): Handle closures and new byte-code-functions.
5173 (Fspecial_variable_p): New function.
5174 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
5175 but without exporting it to Lisp.
5177 * doc.c (Fdocumentation, store_function_docstring):
5178 * data.c (Finteractive_form): Handle closures.
5180 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
5183 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
5185 (exec_byte_code): New function extracted from Fbyte_code to handle new
5186 calling convention for byte-code-functions. Add new byte-codes.

5194 * xdisp.c (redisplay_internal): Fix prototype.
5196 2011-03-31 Eli Zaretskii <eliz@gnu.org>
5198 * xdisp.c (SCROLL_LIMIT): New macro.
5199 (try_scrolling): Use it when setting scroll_limit.
5200 Limit scrolling to 100 screen lines.
5201 (redisplay_window): Even when falling back on "recentering",
5202 position point in the window according to scroll-conservatively,
5203 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
5205 (try_scrolling): When point is above the window, allow searching
5206 as far as scroll_max, or one screenful, to compute vertical
5207 distance from PT to the scroll margin position. This prevents
5208 try_scrolling from unnecessarily failing when
5209 scroll-conservatively is set to a value slightly larger than the
5210 window height. Clean up the case of PT below the margin at bottom
5211 of window: scroll_max can no longer be INT_MAX. When aggressive
5212 scrolling is in use, don't let point enter the opposite scroll
5213 margin as result of the scroll.
5214 (syms_of_xdisp) <scroll-conservatively>: Document the
5215 threshold of 100 lines for never-recentering scrolling.

5223 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5224 (redisplay_internal): Remove parameter `preserve_echo_area',
5225 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
5227 * indent.c (Fvertical_motion):
5228 * window.c (window_scroll_pixel_based, Frecenter):
5229 Don't pass `need_y_p' to `move_it_by_lines'.
5231 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
5233 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
5234 steal a few bits to be more compact.
5235 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
5236 Remove unneeded casts.
5238 * bytecode.c (Fbyte_code): CAR and CDR can GC.
5240 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
5242 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
5243 binding" message (bug#7967).
5245 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
5247 Fix more problems found by GCC 4.6.0's static checks.
5249 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
5250 Remove unused local var.
5252 * editfns.c (Fmessage_box): Remove unused local var.
5254 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
5255 (note_mode_line_or_margin_highlight, note_mouse_highlight):
5256 Omit unused local vars.
5257 * window.c (shrink_windows): Omit unused local var.
5258 * menu.c (digest_single_submenu): Omit unused local var.
5259 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
5260 Omit unused local var.
5262 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
5263 Don't assume string length fits in int.
5264 (keyremap_step, read_key_sequence): Use size_t for sizes.
5265 (read_key_sequence): Don't check last_real_key_start redundantly.
5267 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
5268 instead of alloca (Bug#8344).
5270 * eval.c (Fbacktrace): Don't assume nargs fits in int.

5280 * cm.c (calccost): Turn while-do into do-while, for clarity.
5282 * keyboard.c (syms_of_keyboard): Use the same style as later
5283 in this function when indexing through an array. This also
5284 works around GCC bug 48267.
5286 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
5288 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
5290 * chartab.c (sub_char_table_ref_and_range): Redo for slight
5291 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
5293 * keyboard.c, keyboard.h (num_input_events): Now size_t.
5294 This avoids undefined behavior on integer overflow, and is a bit
5295 more convenient anyway since it is compared to a size_t variable.
5297 Variadic C functions now count arguments with size_t, not int.
5298 This avoids an unnecessary limitation on 64-bit machines, which
5299 caused (substring ...) to crash on large vectors (Bug#8344).
5300 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.

5309 * fns.c (concat): Likewise.
5310 * frame.c (x_set_frame_parameters): Likewise.
5311 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
5312 0 if not found, not -1. All callers changed.
5314 * alloc.c (garbage_collect): Don't assume stack size fits in int.
5315 (stack_copy_size): Now size_t, not int.
5316 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
5318 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
5320 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
5321 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
5322 All callers changed.

5337 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
5338 don't set the hook to nil, but remove the offending function instead.
5339 (Qcommand_hook_internal): Remove, unused.
5340 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
5341 Vcommand_hook_internal.

5344 (funcall_nil, funcall_not): New functions.
5345 (run_hook_with_args): Call each function through a `funcall' argument.

5364 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
5365 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.

5438 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
5440 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
5441 incurred during fontification.

5517 * emacs.c (Fkill_emacs):
5518 * editfns.c (save_excursion_restore):
5519 * cmds.c (internal_self_insert):
5520 * callint.c (Fcall_interactively):
5521 * buffer.c (Fkill_all_local_variables):
5522 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
5524 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
5525 unconditionnaly since it does the check itself.
5527 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
5529 Fix more problems found by GCC 4.5.2's static checks.
5531 * coding.c (encode_coding_raw_text): Avoid unnecessary test
5532 the first time through the loop, since we know p0 < p1 then.
5533 This also avoids a gcc -Wstrict-overflow warning.
5535 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
5536 leading to a memory leak, possible in functions like
5537 load_charset_map_from_file that can allocate an unbounded number
5538 of objects (Bug#8318).
5540 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
5541 that could (at least in theory) be that large.
5543 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
5544 This is less likely to overflow, and avoids undefined behavior if
5545 overflow does occur. All callers changed. Use strtoul to scan
5546 for the unsigned long integer.
5547 (pint2hrstr): Simplify and tune code slightly.
5548 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
5550 * scroll.c (do_scrolling): Work around GCC bug 48228.
5551 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

5554 This also avoids a warning with gcc -Wstrict-overflow.
5555 (validate_x_resource_name): Simplify count usage.
5556 This also avoids a warning with gcc -Wstrict-overflow.
5558 * fileio.c (Fcopy_file): Report error if fchown or fchmod
5561 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
5563 * process.c (Fmake_network_process): Use socklen_t, not int,
5564 where POSIX says socklen_t is required in portable programs.
5565 This fixes a porting bug on hosts like 64-bit HP-UX, where
5566 socklen_t is wider than int (Bug#8277).
5567 (Fmake_network_process, server_accept_connection):
5568 (wait_reading_process_output, read_process_output):

5581 Make tparam.h and terminfo.c consistent.
5582 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
5583 Include tparam.h instead, since it declares them.
5584 * cm.h (PC): Remove extern decl; tparam.h now does this.
5585 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
5586 * terminfo.c: Include tparam.h, to check interfaces.
5587 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
5588 (tparam): Adjust signature to match interface in tparam.h;
5589 this removes some undefined behavior. Check that outstring and len
5590 are zero, which they always are with Emacs.
5591 * tparam.h (PC, BC, UP): New extern decls.
5593 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
5594 (xftfont_open): Rename locals to avoid shadowing.
5596 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

5612 (composition_update_it): Mark var as initialized.
5613 (find_automatic_composition): Mark vars as initialized,
5614 with a FIXME (Bug#8290).
5616 character.h: Rename locals to avoid shadowing.
5617 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
5618 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
5619 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
5620 (BUF_DEC_POS): Be more systematic about renaming local temporaries
5623 * textprop.c (property_change_between_p): Remove; unused.
5625 * intervals.c (interval_start_pos): Now static.
5627 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
5629 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
5630 Rename locals to avoid shadowing.
5632 * sound.c (wav_play, au_play, Fplay_sound_internal):
5633 Fix pointer signedness.
5634 (alsa_choose_format): Remove unused local var.
5635 (wav_play): Initialize a variable to 0, to prevent undefined
5636 behavior (Bug#8278).
5638 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
5640 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
5642 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
5643 clobbering (Bug#8298).
5644 * sysdep.c (sys_subshell): Likewise.
5645 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
5647 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
5648 This should get cleaned up, so that child_setup has the
5649 same signature on all platforms.
5651 * callproc.c (call_process_cleanup): Now static.
5652 (relocate_fd): Rename locals to avoid shadowing.
5654 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
5656 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
5657 not to be necessary, and produces flickering.
5659 2011-03-20 Glenn Morris <rgm@gnu.org>
5661 * config.in: Remove file.
5663 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
5665 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
5666 are now in src/globals.h.
5667 (syms_of_minibuf): Remove spurious & from previous change.
5669 2011-03-20 Leo <sdl.web@gmail.com>
5671 * minibuf.c (completing-read-function): New variable.
5672 (completing-read-default): Rename from completing-read.
5673 (completing-read): Call completing-read-function.
5675 2011-03-19 Juanma Barranquero <lekktu@gmail.com>

5678 Read color file from absolute filename (bug#8250).
5680 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
5682 * makefile.w32-in: Update dependencies.
5684 2011-03-17 Eli Zaretskii <eliz@gnu.org>
5686 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
5688 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>

5693 (sigchld_handler): Now static.
5695 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
5696 That way, the code declares only the vars that it needs.

5702 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
5703 * process.c (allocate_pty): Don't declare stb unless it's needed.
5705 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
5706 (CONSTANTLIM): Remove; unused.
5707 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
5708 Define only if needed.
5710 * unexelf.c (unexec): Name an expression,
5711 to avoid gcc -Wbad-function-cast warning.
5712 Use a different way to cause a compilation error if anyone uses
5713 n rather than nn, a way that does not involve shadowing.
5714 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
5716 * deps.mk (unexalpha.o): Remove; unused.
5718 New file unexec.h, the (simple) interface for unexec (Bug#8267).
5719 * unexec.h: New file.
5720 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
5721 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
5723 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
5724 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
5725 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.

5735 * lread.c (read1): Rewrite so as not to use empty "else".
5736 (Fload, readevalloop, read1): Rename locals to avoid shadowing.
5738 * print.c (Fredirect_debugging_output): Fix pointer signedess.
5740 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
5741 warning when compiling print.c.
5743 * font.c (font_unparse_fcname): Abort in an "impossible" situation
5744 instead of using an uninitialized var.
5745 (font_sort_entities): Mark var as initialized.
5747 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
5749 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

5781 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
5782 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
5783 some of which prompt warnings from gcc -Wbad-function-cast.
5784 (Fformat_time_string, Fencode_time, Finsert_char):
5785 (Ftranslate_region_internal, Fformat):
5786 Rename or remove local vars to avoid shadowing.

5804 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
5805 Rename locals to avoid shadowing.
5806 (mark_stack): Move local variables into the #ifdef region where
5808 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
5809 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
5811 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.

5816 avoids undefined behavior in theory.
5818 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
5820 Use functions, not macros, for up- and down-casing (Bug#8254).
5821 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5822 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
5823 to use the following functions instead of these macros.
5824 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
5825 EMACS_INT, since callers assume the returned value fits in int.
5826 (upcase1): Likewise, for UPCASE_TABLE.
5827 (uppercasep, lowercasep, upcase): New static inline functions.
5828 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

5834 (regex_compile, re_search_2, re_match_2_internal):
5835 Remove unused local vars.
5836 (FREE_VAR): Rewrite so as not to use empty "else",
5837 which gcc can warn about.
5838 (regex_compile, re_match_2_internal): Mark locals as initialized.
5839 (RETALLOC_IF): Define only if needed.
5840 (WORDCHAR_P): Likewise. This one is never needed, but is used
5841 only in a comment talking about a compiler bug, so put inside
5842 the #if 0 of that comment.
5843 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
5844 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
5847 * search.c (boyer_moore): Rename locals to avoid shadowing.
5848 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
5849 (PREV_CHAR_BOUNDARY): Likewise.
5851 * search.c (simple_search): Remove unused var.
5853 * dired.c (compile_pattern): Move decl from here ...

5866 (casify_region): Mark local as initialized.
5868 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
5870 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
5871 New macros, so that the caller can use some names other than
5872 gcpro1, gcpro2, etc.
5873 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
5875 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
5876 argument, for consistency with GCPRO2_VAR, etc: it is now the
5877 prefix of the variable, not the variable itself. All uses
5879 * dired.c (directory_files_internal, file_name_completion):
5880 Rename locals to avoid shadowing.
5882 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
5883 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
5884 dired.c's scmp function, had undefined behavior.
5885 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5886 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
5887 * buffer.h: ... to here, because these macros use current_buffer,
5888 and the new implementation with inline functions needs to have
5889 current_buffer in scope now, rather than later when the macros
5891 (downcase, upcase1): New static inline functions.
5892 (DOWNCASE, UPCASE1): Reimplement using these functions.
5893 This avoids undefined behavior in expressions like
5894 DOWNCASE (x) == DOWNCASE (y), which previously suffered
5895 from race conditions in accessing the global variables
5896 case_temp1 and case_temp2.
5897 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
5898 * lisp.h (case_temp1, case_temp2): Remove their decls.
5899 * character.h (ASCII_CHAR_P): Move from here ...
5900 * lisp.h: ... to here, so that the inline functions mentioned
5903 * dired.c (directory_files_internal_unwind): Now static.
5905 * fileio.c (file_name_as_directory, directory_file_name):
5906 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
5908 (file_name_as_directory): Use const pointers when appropriate.
5909 (Fexpand_file_name): Likewise. In particular, newdir might
5910 point at constant storage, so make it a const pointer.
5911 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
5912 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
5914 (Fset_file_times, Finsert_file_contents, auto_save_error):
5915 Rename locals to avoid shadowing.
5917 * minibuf.c (choose_minibuf_frame_1): Now static.
5918 (Ftry_completion, Fall_completions): Rename or remove locals
5921 * marker.c (bytepos_to_charpos): Remove; unused.
5923 * lisp.h (verify_bytepos, count_markers): New decls,
5924 so that gcc does not warn that these functions aren't declared.
5926 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
5927 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
5928 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
5929 (copy_text): Remove unused local var.
5931 * filelock.c (within_one_second): Now static.
5932 (lock_file_1): Rename local to avoid shadowing.
5934 * buffer.c (fix_overlays_before): Mark locals as initialized.
5935 (fix_start_end_in_overlays): Likewise. This function should be
5936 simplified by using pointers-to-pointers, but that's a different
5938 (switch_to_buffer_1): Now static.
5939 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
5940 (report_overlay_modification): Rename locals to avoid shadowing.
5942 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
5943 Fix pointer signedness issue.
5944 (sys_subshell): Mark local as volatile if checking for lint,
5945 to suppress a gcc -Wclobbered warning that does not seem to be right.
5946 (MAXPATHLEN): Define only if needed.
5948 * process.c (serial_open, serial_configure): Move decls from here ...
5949 * systty.h: ... to here, so that they can be checked.
5951 * fns.c (get_random, seed_random): Move extern decls from here ...
5952 * lisp.h: ... to here, so that they can be checked.
5954 * sysdep.c (reset_io): Now static.
5955 (wait_for_termination_signal): Remove; unused.
5957 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

5963 (describe_map_tree):
5964 Rename locals to avoid shadowing.
5966 * keyboard.c: Declare functions static if they are not used elsewhere.
5967 (echo_char, echo_dash, cmd_error, top_level_2):
5968 (poll_for_input, handle_async_input): Now static.
5969 (read_char, kbd_buffer_get_event, make_lispy_position):
5970 (make_lispy_event, make_lispy_movement, apply_modifiers):
5971 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
5972 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
5973 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
5974 (read_key_sequence, read_char): Mark locals as initialized.
5975 (Fexit_recursive_edit, Fabort_recursive_edit): Mark with NO_RETURN.
5977 * keyboard.h (make_ctrl_char): New decl.
5978 (mark_kboards): Move decl here ...
5979 * alloc.c (mark_kboards): ... from here.
5981 * lisp.h (force_auto_save_soon): New decl.
5983 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
5984 (DEFINE_DUMMY_FUNCTION): New macro.
5985 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
5987 (main): Add casts to avoid warnings
5988 if GCC considers string literals to be constants.
5990 * lisp.h (fatal_error_signal): Add decl, since it's exported.
