217 * image.c (xpm_get_color_table_h):
218 * lisp.h (hash_lookup, hash_put):
219 * minibuf.c (Ftest_completion):
220 Use ptrdiff_t for hash table indexes, not int (which is too
221 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
222 32-bit --with-wide-int hosts).
224 * charset.c (Fdefine_charset_internal): Check for integer overflow.
225 Add a FIXME comment about memory leaks.
226 (syms_of_charset): Don't assume xmalloc returns.

232 Use sanitize_char_width to avoid undefined and/or bad behavior
233 with outlandish widths.
234 * character.h (sanitize_tab_width): Renamed from sanitize_width,
235 now that we have two such functions. All uses changed.
236 (sanitize_char_width): New inline function.

253 * xterm.c: don't go over XClientMessageEvent limit
254 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
255 (x_send_scroll_bar_event): Likewise. Check that the size does not
256 exceed limits imposed by XClientMessageEvent, as well as the usual
257 ptrdiff_t and size_t limits.
259 * keyboard.c: Overflow, signedness and related fixes.
260 (make_lispy_movement): Use same integer type in forward decl
261 that is used in the definition.
262 (read_key_sequence, keyremap_step):
263 Change bufsize argument back to int, undoing my 2011-03-30 change.
264 We prefer signed types, and int is wide enough here.
265 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
266 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
267 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
268 length, not size_t. Use ptrdiff_t for index, not int.
269 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
270 possibility of integer overflow.
272 Overflow, signedness and related fixes for images.

282 * xdisp.c (calc_pixel_width_or_height):

288 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

291 when the callers expect that.
292 (image_ascent): Redo ascent calculation to avoid int overflow.
293 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
294 (lookup_image): Remove unnecessary tests.
295 (xbm_image_p): Locals are now of int, not EMACS_INT,
296 since parse_image_check makes sure they fit into int.
297 (png_load, gif_load, svg_load_image):
298 Prefer int to unsigned where either will do.
299 (tiff_handler): New function, combining the cores of the
300 old tiff_error_handler and tiff_warning_handler. This
301 function is rewritten to use vsnprintf and thereby avoid
302 stack buffer overflows. It uses only the features of vsnprintf
303 that are common to both POSIX and native Microsoft.
304 (tiff_error_handler, tiff_warning_handler): Use it.
305 (tiff_load, gif_load, imagemagick_load_image):
306 Don't assume :index value fits in 'int'.
307 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
308 (imagemagick_load_image): Check that crop parameters fit into
309 the integer types that MagickCropImage accepts. Don't assume
310 Vimagemagick_render_type has a nonnegative value. Don't assume
311 size_t fits in 'long'.
312 (gs_load): Use printmax_t to print the widest integers possible.

319 * bidi.c: Integer size and overflow fixes.
320 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
321 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
322 (bidi_cache_find_level_change, bidi_cache_ensure_space)
323 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
324 (bidi_find_other_level_edge):
325 Use ptrdiff_t instead of EMACS_INT where either will do.
326 This works better on 32-bit hosts configured --with-wide-int.
327 (bidi_cache_ensure_space): Check for size-calculation overflow.
328 Use % rather than repeated addition, for better worst-case speed.
329 Don't set bidi_cache_size until after xrealloc returns, because it
331 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
332 (bidi_cache_ensure_space): Also check that the bidi cache size
333 does not exceed that of the largest Lisp string or buffer. See Eli
334 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
336 * alloc.c (__malloc_size_t): Remove.
337 All uses replaced by size_t. See Andreas Schwab's note
338 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
340 * image.c: Improve checking for integer overflow.
341 (check_image_size): Assume that f is nonnull, since
342 it is always nonnull in practice. This is one less thing to
343 worry about when checking for integer overflow later.
344 (x_check_image_size): New function, which checks for integer
345 overflow issues inside X.
346 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
347 This removes the need for a memory_full check.
348 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
349 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
350 (xbm_read_bitmap_data): Change locals back to 'int', since
351 their values must fit in 'int'.
352 (xpm_load_image, png_load, tiff_load):
353 Invoke x_create_x_image_and_pixmap earlier,
354 to avoid much needless work if the image is too large.
355 (tiff_load): Treat overly large images as if
356 x_create_x_image_and_pixmap failed, not as malloc failures.
357 (gs_load): Use x_check_image_size.
359 * gtkutil.c: Omit integer casts.
360 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
361 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
363 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
365 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
366 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
367 would wrongly return t on a 64-bit host.
369 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
370 The plain *_OVERFLOW macros run afoul of GCC bug 49705
371 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
372 and therefore cause GCC to emit a bogus diagnostic in some cases.
374 * image.c: Integer signedness and overflow and related fixes.
375 This is not an exhaustive set of fixes, but it's time to
376 record what I've got.
377 (lookup_pixel_color, check_image_size): Remove redundant decls.
378 (check_image_size): Don't assume that arbitrary EMACS_INT values
379 fit in 'int', or that arbitrary 'double' values fit in 'int'.

381 (tiff_load, imagemagick_load_image):
382 Check for overflow in size calculations.
383 (x_create_x_image_and_pixmap): Remove unnecessary test for
384 xmalloc returning NULL; that can't happen.

386 (xpm_color_bucket): Use better integer hashing function.
387 (xpm_cache_color): Don't possibly over-allocate memory.
388 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
390 Use ptrdiff_t, not int or size_t, to record sizes.
391 (png_load): Don't assume values greater than 2**31 fit in 'int'.
392 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
393 either works, as we prefer signed integers.
394 (tiff_read_from_memory, tiff_write_from_memory):
395 Return tsize_t, not size_t, since that's what the TIFF API wants.
396 (tiff_read_from_memory): Don't fail simply because the read would
397 go past EOF; instead, return a short read.
398 (tiff_load): Omit no-longer-needed casts.
399 (Fimagemagick_types): Don't assume size fits into 'int'.
401 Improve hashing quality when configured --with-wide-int.
402 * fns.c (hash_string): New function, taken from sxhash_string.
403 Do not discard information about ASCII character case; this
404 discarding is no longer needed.
405 (sxhash-string): Use it. Change sig to match it. Caller changed.
406 * lisp.h: Declare it.
407 * lread.c (hash_string): Remove, since we now use fns.c's version.
408 The fns.c version returns a wider integer if --with-wide-int is
409 specified, so this should help the quality of the hashing a bit.
411 * emacs.c: Integer overflow minor fix.
412 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
413 Define only if GNU_LINUX.
414 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
416 * dispnew.c: Integer signedness and overflow fixes.
417 Remove unnecessary forward decls, that were a maintenance hassle.
418 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
420 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
421 (scrolling_window): Use ptrdiff_t, not int, for byte count.
422 (prepare_desired_row, line_draw_cost):
423 Use int, not unsigned, where either works.
424 (save_current_matrix, restore_current_matrix):
425 Use ptrdiff_t, not size_t, where either works.
426 (init_display): Check for overflow more accurately, and without
427 relying on undefined behavior.
429 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
430 Remove, replacing with the new symbols in lisp.h. All uses changed.
431 * fileio.c (make_temp_name):
432 * filelock.c (lock_file_1, lock_file):
433 * xdisp.c (message_dolog):
434 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
435 Use pMd etc. instead.
436 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
437 replacing the pWIDE etc. symbols removed from editfns.c.
439 * keyboard.h (num_input_events): Now uintmax_t.
440 This is (very slightly) less likely to mess up due to wraparound.
443 * buffer.c: Integer signedness fixes.
444 (alloc_buffer_text, enlarge_buffer_text):
445 Use ptrdiff_t rather than size_t when either will do, as we prefer
448 * alloc.c: Integer signedness and overflow fixes.
449 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
450 (__malloc_size_t): Default to size_t, not to int.
451 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
452 (Fgarbage_collect, mark_object_loop_halt, mark_object):
453 Prefer ptrdiff_t to size_t when either would do, as we prefer
455 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
456 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
457 Now const. Initialize with values that are in range even if char
459 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
460 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
461 These functions do the right thing with sizes > 2**32.
462 (check_depth): Now ptrdiff_t, not int.
463 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
464 Adjust to new way of storing sizes. Check for size overflow bugs
466 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
467 slightly wrong anyway, as it missed one instance of
468 XMALLOC_OVERRUN_CHECK_OVERHEAD.
469 (refill_memory_reserve): Omit needless cast to size_t.
470 (mark_object_loop_halt): Mark as externally visible.
472 * xselect.c: Integer signedness and overflow fixes.
473 (Fx_register_dnd_atom, x_handle_dnd_message):
474 Use ptrdiff_t, not size_t, since we prefer signed.
475 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
476 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
477 x_dnd_atoms_size and x_dnd_atoms_length.
479 * doprnt.c: Prefer signed to unsigned when either works.
483 * xdisp.c (vmessage):
484 Use ptrdiff_t, not size_t, when using or implementing doprnt,
485 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
486 prefer signed arithmetic to avoid comparison confusion.
487 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
490 Assume freestanding C89 headers, string.h, stdlib.h.
491 * data.c, doprnt.c, floatfns.c, print.c:
492 Include float.h unconditionally.
493 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
494 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
495 * regex.c: Likewise for stddef.h, string.h.
496 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
497 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
498 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
499 (STDC_HEADERS): Remove obsolete defines.
500 * sysdep.c: Include limits.h unconditionally.
502 Assume support for memcmp, memcpy, memmove, memset.
503 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
504 * regex.c (memcmp, memcpy):
505 Remove; we assume C89 now.
507 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
508 (__malloc_safe_bcopy): Remove; no longer needed.
510 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
511 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
512 well either way, and we prefer signed to unsigned.

517 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
518 and the surrounding thread.
519 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
520 rather than fgets, and retry after EINTR. Otherwise, 'emacs
521 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
523 * s/openbsd.h (BROKEN_SIGIO): Define.
524 * unexelf.c (unexec) [__OpenBSD__]:
525 Don't update the .mdebug section of the Alpha COFF symbol table.
527 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
529 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
532 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
534 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
535 This fixes some race conditions on the permissions of any newly
538 * alloc.c (valid_pointer_p): Use pipe, not open.
539 This fixes some permissions issues when debugging.
541 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
542 If fchown fails to set both uid and gid, try to set just gid,
543 as that is sometimes allowed. Adjust the file's mode to eliminate
544 setuid or setgid bits that are inappropriate if fchown fails.
546 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
548 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
549 to compare Lisp_Objects.

560 symbol character follows.
562 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
564 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
565 This works around a problem with the previous change to Fcopy_file.
566 Recent glibc declares fchown with __attribute__((warn_unused_result)),
567 and without this change, GCC might complain about discarding
568 fchown's return value.
570 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
572 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
574 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
576 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
578 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
580 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
581 it's used from the C level.
583 * process.c: Use the same condition for POLL_FOR_INPUT in both
584 keyboard.c and process.c (bug#1858).
586 2011-07-09 Lawrence Mitchell <wence@gmx.li>
588 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
589 (Fgnutls_boot): Use it.
591 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
593 * doc.c (Fsubstitute_command_keys): Revert last change.
595 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
597 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
598 quotes the next character, and doesn't affect other longer
599 sequences (bug#8935).
601 * lread.c (syms_of_lread): Clarify that is isn't only
602 `eval-buffer' and `eval-defun' that's affected by
603 `lexical-binding' (bug#8460).
605 2011-07-15 Eli Zaretskii <eliz@gnu.org>
607 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
608 bidi redisplay when a line includes both an image and is

613 Fix minor problems found by static checking.
614 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
615 (elsz): Now a signed constant, not a size_t var. We prefer signed
616 types to unsigned, to avoid integer comparison confusion. Without
617 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
618 "cannot optimize loop, the loop counter may overflow", a symptom
620 * indent.c (Fvertical_motion): Mark locals as initialized.
621 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
623 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
625 * search.c (Fre_search_backward): Mention `case-fold-search' in
626 all the re_search_* functions (bug#8138).
628 * keyboard.c (Fopen_dribble_file): Document when the file is

646 buffer position was specified. Initialize paragraph_embedding to
648 (reseat_to_string): Initialize the bidi iterator.
649 (display_string): If we need to ignore text properties of
650 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
651 original value of -1 will not work with bidi.)
652 (compute_display_string_pos): First arg is now struct

661 calculation of the object to scan. Fixes an error when using
663 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
664 base_level_stop; instead, set base_level_stop to BEGV. Fixes
665 crashes in vertical-motion.
666 (next_element_from_buffer): Improve commentary for when
667 the iterator is before prev_stop.
668 (init_iterator): Initialize bidi_p from the default value of
669 bidi-display-reordering, not from buffer-local value. Use the
670 buffer-local value only if initializing for buffer iteration.
671 (handle_invisible_prop): Support invisible properties on strings
672 that are being bidi-reordered.
673 (set_iterator_to_next): Support bidi reordering of C strings and

690 (get_visually_first_element): New function, refactored from common
691 parts of next_element_from_buffer, next_element_from_string, and
692 next_element_from_c_string.
693 (tool_bar_lines_needed, redisplay_tool_bar)

711 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
712 and we are bidi-iterating, don't decrement the iterator position;
713 instead, set the first_elt flag in the bidi iterator, to produce
715 (reseat_1): Remove redundant setting of string_from_display_prop_p.
716 (push_display_prop): xassert that we are iterating a buffer.
717 (push_it, pop_it): Save and restore paragraph_embedding member.

719 (get_overlay_strings_1, reseat_1, reseat_to_string)
720 (push_display_prop): Set up the `unibyte' member of bidi_it.string
721 correctly. Don't assume unibyte strings are not bidi-reordered.

727 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
728 (pop_it): Call iterate_out_of_display_property only if we are
729 popping after iteration over a string that came from a display
730 property. Fix a typo in popping stretch info. Add an assertion
731 for verifying that the iterator position is in sync with the bidi
733 (handle_single_display_spec, get_overlay_strings_1)

740 (handle_stop, back_to_previous_visible_line_start, reseat_1):
741 Reset the from_disp_prop_p flag.
742 (SAVE_IT, RESTORE_IT): New macros.

807 always valid if bidi_cache_idx is valid.
808 (bidi_cache_find_level_change): xassert that bidi_cache_last_idx

1183 Random fixes. E.g., (random) never returned negative values.
1184 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
1185 subseconds part to the entropy, as that's a bit more random.
1186 Prefer signed to unsigned, since the signedness doesn't matter and
1187 in general we prefer signed. When given a limit, use a
1188 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
1189 latter isn't right if USE_2_TAGS_FOR_INTS.
1190 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
1191 not 0..VALMASK. Don't discard "excess" bits that random () returns.

1204 This is more efficient than Ffile_directory_p and avoids a minor race.
1206 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
1208 * buffer.c (Foverlay_put): Say what the return value is
1211 * fileio.c (barf_or_query_if_file_exists): Check first if the file

1214 (barf_or_query_if_file_exists): Make the "File is a directory"
1215 error be more correct.
1217 * fns.c (Frequire): Remove the mention of the .gz files, since
1218 that's installation-specific, but keep the mention of
1219 `get-load-suffixes'.
1221 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
1223 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

1234 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

1336 * eval.c (struct backtrace): Simplify and port the data structure.
1337 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
1338 signed bit field, as this assumption is not portable and it makes
1339 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
1340 "char debug_on_exit : 1" as this is not portable either; instead,
1341 use the portable "unsigned int debug_on_exit : 1". Remove unused
1342 member evalargs. Remove obsolete comments about cc bombing out.

1415 frames size_hint to set minimum and natural (Bug#8919).
1416 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
1417 and use min_width/height from frames size_hint to set
1418 min_width/height (Bug#8919).

1432 * process.c (wait_reading_process_output): Bypass select if
1433 waiting for a cell while ignoring keyboard input, and input is
1434 pending. Suggested by Jan Djärv (Bug#8869).
1436 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
1438 Use gnulib's dup2 module instead of rolling our own.
1439 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

1506 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
1508 Integer and buffer overflow fixes (Bug#8873).
1510 * print.c (printchar, strout): Check for string overflow.
1511 (PRINTPREPARE, printchar, strout):
1512 Don't set size unless allocation succeeds.
1514 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
1515 for sizes. Check for string overflow more accurately.
1516 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
1518 * macros.c: Integer and buffer overflow fixes.
1519 * keyboard.h (struct keyboard.kbd_macro_bufsize):
1520 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

1522 Don't increment bufsize until after realloc succeeds.
1523 Check for size-calculation overflow.
1524 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
1526 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
1528 * lread.c: Integer overflow fixes.
1529 (read_integer): Radix is now EMACS_INT, not int,
1530 to improve quality of diagnostics for out-of-range radices.
1531 Calculate buffer size correctly for out-of-range radices.
1532 (read1): Check for integer overflow in radices, and in
1533 read-circle numbers.
1534 (read_escape): Avoid int overflow.
1535 (Fload, openp, read_buffer_size, read1)
1536 (substitute_object_recurse, read_vector, read_list, map_obarray):

1550 (read_escape): Check for hex character overflow.
1552 2011-06-22 Leo Liu <sdl.web@gmail.com>
1554 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
1555 Move to minibuffer.el.
1557 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
1559 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
1560 The following patches are for when GLYPH_DEBUG && !XASSERT.
1561 * dispextern.h (trace_redisplay_p, dump_glyph_string):
1562 * dispnew.c (flush_stdout):
1563 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
1564 Mark as externally visible.
1565 * dispnew.c (check_window_matrix_pointers): Now static.
1566 * dispnew.c (window_to_frame_vpos):
1567 * xfns.c (unwind_create_frame):
1568 * xterm.c (x_check_font): Remove unused local.
1569 * scroll.c (CHECK_BOUNDS):
1570 * xfaces.c (cache_fache): Rename local to avoid shadowing.
1571 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
1572 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
1573 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
1574 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
1576 (debug_method_add): Use va_list and vsprintf rather than relying
1577 on undefined behavior with wrong number of arguments.
1578 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
1579 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
1580 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
1581 since we're not interested in debugging glyphs with old libraries.
1582 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
1583 GCC 4.6.0's static checking.
1585 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
1587 Integer overflow and signedness fixes (Bug#8873).

1596 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
1597 (x_create_bitmap_from_xpm_data):
1598 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
1599 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
1601 * xfaces.c (load_pixmap):
1602 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
1603 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
1604 (.bitmaps_last, struct x_output.icon_bitmap):
1605 Use ptrdiff_t, not int, for bitmap indexes.
1606 (x_allocate_bitmap_record): Check for size overflow.
1607 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
1609 Use ptrdiff_t, not int, for overlay counts.
1610 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
1611 * editfns.c (overlays_around, get_pos_property):
1612 * textprop.c (get_char_property_and_overlay):
1613 * xdisp.c (next_overlay_change, note_mouse_highlight):
1614 * xfaces.c (face_at_buffer_position):
1615 * buffer.c (OVERLAY_COUNT_MAX): New macro.
1616 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
1617 (Fnext_overlay_change, Fprevious_overlay_change)
1618 (mouse_face_overlay_overlaps, Foverlays_in):
1619 Use ptrdiff_t, not int, for sizes.
1620 (overlays_at, overlays_in): Check for size-calculation overflow.
1622 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
1624 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
1625 (x_session_initialize): Do not assume string length fits in int.
1627 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
1628 This is unlikely, but can occur if DPI is outlandish.
1630 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
1631 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
1633 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
1634 * xrdb.c (magic_file_p, search_magic_path):
1635 Omit last arg SUFFIX; it was always 0. All callers changed.
1636 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
1638 * xfont.c (xfont_match): Avoid need for strlen.
1640 * xfns.c: Don't assume strlen fits in int.

1643 * xdisp.c (message_log_check_duplicate): Return intmax_t,
1644 not unsigned long, as we prefer signed integers. All callers changed.
1645 Detect integer overflow in repeat count.
1646 (message_dolog): Don't assume print length fits in 39 bytes.
1647 (display_mode_element): Don't assume strlen fits in int.
1649 * termcap.c: Don't assume sizes fit in int and never overflow.
1650 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
1651 (gobble_line): Check for size-calculation overflow.
1653 * minibuf.c (Fread_buffer):
1654 * lread.c (intern, intern_c_string):
1655 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
1656 Don't assume string length fits in int.
1658 * keyboard.c (parse_tool_bar_item):
1659 * gtkutil.c (style_changed_cb): Avoid need for strlen.
1661 * font.c: Don't assume string length fits in int.
1662 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
1663 Use ptrdiff_t, not int.
1664 (font_intern_prop): Don't assume string length fits in int.
1665 Don't assume integer property fits in fixnum.
1666 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
1668 * filelock.c: Fix some buffer overrun and integer overflow issues.
1669 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
1670 Reformulate so as not to need the command string.
1671 Invoke gzip -cd rather than gunzip, as it's more portable.
1672 (lock_info_type, lock_file_1, lock_file):
1673 Don't assume pid_t and time_t fit in unsigned long.
1674 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
1675 (current_lock_owner): Prefer signed type for sizes.
1676 Use memcpy, not strncpy, where memcpy is what is really wanted.
1677 Don't assume (via atoi) that time_t and pid_t fit in int.
1678 Check for time_t and/or pid_t out of range, e.g., via a network share.
1679 Don't alloca where an auto var works fine.
1681 * fileio.c: Fix some integer overflow issues.
1682 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
1683 Don't assume string length fits in int.
1684 (directory_file_name): Don't assume string length fits in long.
1685 (make_temp_name): Don't assume pid fits in int, or that its print
1686 length is less than 20.
1688 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
1690 * coding.c (make_subsidiaries): Don't assume string length fits in int.
1692 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
1694 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
1695 We prefer signed integers, even for size calculations.
1697 * emacs.c: Don't assume string length fits in 'int'.

1706 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
1708 * lread.c (invalid_syntax): Omit length argument.
1709 All uses changed. This doesn't fix a bug, but it simplifies the
1710 code away from its former Hollerith-constant appearance, and it's
1711 one less 'int' to worry about when looking at integer-overflow issues.
1712 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
1714 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
1715 This didn't break anything, but it didn't help either.
1716 It's confusing to put a bogus integer in a place where the actual
1717 value does not matter.
1718 (LIST_END_P): Remove unused macro and its bogus comment.
1719 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
1721 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
1722 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
1724 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
1725 We prefer signed types, and the value cannot exceed the EMACS_INT
1726 range anyway (because otherwise the length would not be representable).
1727 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
1728 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
1729 This avoids a GCC warning when WIDE_EMACS_INT.
1731 * indent.c (sane_tab_width): New function.
1732 (current_column, scan_for_column, Findent_to, position_indentation)
1733 (compute_motion): Use it. This is just for clarity.
1734 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
1736 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
1738 * lisp.h (lint_assume): New macro.
1739 * composite.c (composition_gstring_put_cache):
1740 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
1742 * editfns.c, insdel.c:
1743 Omit unnecessary forward decls, to simplify future changes.
1745 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
1747 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
1749 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
1750 Use much-faster test for byte-length change.
1751 Don't assume string byte-length fits in 'int'.
1752 Check that character arg fits in 'int'.
1753 (mapcar1): Declare byte as byte, for clarity.
1755 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
1757 * fns.c (concat): Catch string overflow earlier.
1758 Do not rely on integer wraparound.
1760 * dispextern.h (struct it.overlay_strings_charpos)
1761 (struct it.selective): Now EMACS_INT, not int.
1762 * xdisp.c (forward_to_next_line_start)
1763 (back_to_previous_visible_line_start)
1764 (reseat_at_next_visible_line_start, next_element_from_buffer):
1765 Don't arbitrarily truncate the value of 'selective' to int.
1767 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
1769 * composite.c: Don't truncate sizes to 'int'.
1770 (composition_gstring_p, composition_reseat_it)
1771 (composition_adjust_point): Use EMACS_INT, not int.
1772 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
1773 not EMACS_UINT, for indexes.
1775 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
1777 * buffer.c: Include <verify.h>.
1778 (struct sortvec.priority, struct sortstr.priority):
1779 Now EMACS_INT, not int.
1780 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
1781 (struct sortstr.size, record_overlay_string)
1782 (struct sortstrlist.size, struct sortlist.used):
1783 Don't truncate size to int.
1784 (record_overlay_string): Check for size-calculation overflow.
1785 (init_buffer_once): Check at compile-time, not run-time.
1787 2011-06-22 Jim Meyering <meyering@redhat.com>
1789 Don't leak an XBM-image-sized buffer
1790 * image.c (xbm_load): Free the image buffer after using it.
1792 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
1795 * composite.c (find_automatic_composition): Omit needless 'return 0;'
1796 that Sun C diagnosed.
1797 * fns.c (secure_hash): Fix pointer signedness issue.
1798 * intervals.c (static_offset_intervals): New function.
1799 (offset_intervals): Use it.
1801 2011-06-21 Leo Liu <sdl.web@gmail.com>
1804 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
1807 * fns.c (secure_hash): Rename from crypto_hash_function and change
1808 the first arg to accept symbols.
1809 (Fsecure_hash): New primitive.
1810 (syms_of_fns): New symbols.
1812 2011-06-20 Deniz Dogan <deniz@dogan.se>
1814 * process.c (Fset_process_buffer): Clarify return value in
1817 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
1819 * dispnew.c (add_window_display_history): Use BVAR.
1821 * xdisp.c (debug_method_add): Use BVAR.
1822 (check_window_end, dump_glyph_matrix, dump_glyph)
1823 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
1825 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
1828 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
1829 check till after the cache is created in init_frame_faces.
1831 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
1833 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
1835 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
1837 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
1838 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
1839 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
1841 Improve buffer-overflow checking (Bug#8873).
1842 * fileio.c (Finsert_file_contents):
1843 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
1844 Remove the old (too-loose) buffer overflow checks.
1845 They weren't needed, since make_gap checks for buffer overflow.
1846 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
1847 The old code merely checked for Emacs fixnum overflow, and relied
1848 on undefined (wraparound) behavior. The new code avoids undefined
1849 behavior, and also checks for ptrdiff_t and/or size_t overflow.
1851 * editfns.c (Finsert_char): Don't dump core with very negative counts.
1852 Tune. Don't use wider integers than needed. Don't use alloca.
1853 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
1855 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
1857 * insdel.c, lisp.h (buffer_overflow): New function.
1858 (insert_from_buffer_1, replace_range, replace_range_2):
1859 * insdel.c (make_gap_larger):
1860 * editfns.c (Finsert_char):
1861 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
1863 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
1865 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
1867 Integer overflow and signedness fixes (Bug#8873).
1869 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
1870 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
1872 * fileio.c: Don't assume EMACS_INT fits in off_t.
1873 (emacs_lseek): New static function.
1874 (Finsert_file_contents, Fwrite_region): Use it.
1875 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
1877 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
1879 * fns.c: Don't overflow int when computing a list length.
1880 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
1881 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
1882 truncation on 64-bit hosts. Check for QUIT every
1883 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
1884 faster and is responsive enough.
1885 (Flength): Report an error instead of overflowing an integer.
1886 (Fsafe_length): Return a float if the value is not representable
1887 as a fixnum. This shouldn't happen except in contrived situations.
1888 (Fnthcdr, Fsort): Don't assume list length fits in int.
1889 (Fcopy_sequence): Don't assume vector length fits in int.
1891 * alloc.c: Check that resized vectors' lengths fit in fixnums.
1892 (header_size, word_size): New constants.
1893 (allocate_vectorlike): Don't check size overflow here.
1894 (allocate_vector): Check it here instead, since this is the only
1895 caller of allocate_vectorlike that could cause overflow.
1896 Check that the new vector's length is representable as a fixnum.
1898 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
1899 The previous code was bogus. For example, next_almost_prime (32)
1900 returned 39, which is undesirable as it is a multiple of 3; and
1901 next_almost_prime (24) returned 25, which is a multiple of 5 so
1902 why was the code bothering to check for multiples of 7?
1904 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
1906 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
1908 Variadic C functions now count arguments with ptrdiff_t.
1909 This partly undoes my 2011-03-30 change, which replaced int with size_t.
1910 Back then I didn't know that the Emacs coding style prefers signed int.
1911 Also, in the meantime I found a few more instances where arguments
1912 were being counted with int, which may truncate counts on 64-bit
1913 machines, or EMACS_INT, which may be unnecessarily wide.
1914 * lisp.h (struct Lisp_Subr.function.aMANY)
1915 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
1916 Arg counts are now ptrdiff_t, not size_t.
1917 All variadic functions and their callers changed accordingly.
1918 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
1919 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
1920 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
1921 * callint.c (Fcall_interactively): Check arg count for overflow,
1922 to avoid potential buffer overrun. Use signed char, not 'int',
1923 for 'varies' array, so that we needn't bother to check its size
1924 calculation for overflow.
1925 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
1926 * eval.c (apply_lambda):
1927 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
1928 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
1929 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
1931 * callint.c (Fcall_interactively): Don't use index var as event count.
1933 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
1934 * mem-limits.h (SIZE): Remove; no longer used.
1936 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
1938 Remove unnecessary casts.
1939 * xterm.c (x_term_init):
1940 * xfns.c (x_set_border_pixel):
1941 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
1942 These aren't needed now that we assume ANSI C.
1944 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
1945 It's more likely to cause problems (due to unsigned overflow)
1948 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
1950 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
1952 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
1954 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
1956 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
1958 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
1960 GLYPH_CODE_FACE returns EMACS_INT, not int.
1961 * dispextern.h (merge_faces):
1962 * xfaces.c (merge_faces):
1963 * xdisp.c (get_next_display_element, next_element_from_display_vector):
1964 Don't assume EMACS_INT fits in int.
1966 * character.h (CHAR_VALID_P): Remove unused parameter.
1967 * fontset.c, lisp.h, xdisp.c: All uses changed.
1969 * editfns.c (Ftranslate_region_internal): Omit redundant test.
1971 * fns.c (concat): Minor tuning based on overflow analysis.
1972 This doesn't fix any bugs. Use int to hold character, instead
1973 of constantly refetching from Emacs object. Use XFASTINT, not
1974 XINT, for value known to be a character. Don't bother comparing
1975 a single byte to 0400, as it's always less.
1977 * floatfns.c (Fexpt):
1978 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
1980 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
1983 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
1985 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
1986 Without this fix, on a 64-bit host (aset S 0 4294967386) would
1987 incorrectly succeed when S was a string, because 4294967386 was
1988 truncated before it was used.
1990 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
1991 Otherwise, an out-of-range integer could cause undefined behavior
1994 * composite.c: Use int, not EMACS_INT, for characters.
1995 (fill_gstring_body, composition_compute_stop_pos): Use int, not
1996 EMACS_INT, for values that are known to be in character range.
1997 This doesn't fix any bugs but is the usual style inside Emacs and
1998 may generate better code on 32-bit machines.
2000 Make sure a 64-bit char is never passed to ENCODE_CHAR.
2001 This is for reasons similar to the recent CHAR_STRING fix.
2002 * charset.c (Fencode_char): Check that character arg is actually
2003 a character. Pass an int to ENCODE_CHAR.
2004 * charset.h (ENCODE_CHAR): Verify that the character argument is no
2005 wider than 'int', as a compile-time check to prevent future regressions
2008 * character.c (char_string): Remove unnecessary casts.
2010 Make sure a 64-bit char is never passed to CHAR_STRING.
2011 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
2012 by silently ignoring the top 32 bits, allowing some values
2013 that were far too large to be valid characters.
2014 * character.h: Include <verify.h>.
2015 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
2016 arguments are no wider than unsigned, as a compile-time check
2017 to prevent future regressions in this area.
2019 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
2020 (Fsubst_char_in_region):
2022 * xdisp.c (decode_mode_spec_coding):
2023 Adjust to CHAR_STRING's new requirement.
2024 * editfns.c (Finsert_char, Fsubst_char_in_region):
2025 * fns.c (concat): Check that character args are actually
2026 characters. Without this test, these functions did the wrong
2027 thing with wildly out-of-range values on 64-bit hosts.
2029 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
2030 These casts should not be needed on 32-bit hosts, either.
2031 * keyboard.c (read_char):
2032 * lread.c (Fload): Remove casts to unsigned.
2034 * lisp.h (UNSIGNED_CMP): New macro.
2035 This fixes comparison bugs on 64-bit hosts.
2036 (ASCII_CHAR_P): Use it.
2037 * casefiddle.c (casify_object):
2038 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
2039 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
2040 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
2041 * dispextern.h (FACE_FROM_ID):
2042 * keyboard.c (read_char): Use UNSIGNED_CMP.
2044 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
2045 not to EMACS_INT, to avoid GCC warning.
2047 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
2049 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
2050 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
2051 isn't needed on 32-bit machines.
2053 * buffer.c (Fgenerate_new_buffer_name):
2054 Use EMACS_INT for count, not int.
2055 (advance_to_char_boundary): Return EMACS_INT, not int.
2057 * data.c (Qcompiled_function): Now static.
2059 * window.c (window_body_lines): Now static.
2061 * image.c (gif_load): Rename local to avoid shadowing.
2063 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
2064 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
2065 * alloc.c (make_save_value): Integer argument is now of type
2067 (mark_object): Use ptrdiff_t, not int.
2068 * lisp.h (pD): New macro.
2069 * print.c (print_object): Use it.
2071 * alloc.c: Use EMACS_INT, not int, to count objects.
2072 (total_conses, total_markers, total_symbols, total_vector_size)
2073 (total_free_conses, total_free_markers, total_free_symbols)
2074 (total_free_floats, total_floats, total_free_intervals)
2075 (total_intervals, total_strings, total_free_strings):
2076 Now EMACS_INT, not int. All uses changed.
2077 (Fgarbage_collect): Compute overall total using a double, so that
2078 integer overflow is less likely to be a problem. Check for overflow
2079 when converting back to an integer.
2080 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
2081 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
2082 These were 'int' variables that could overflow on 64-bit hosts;
2083 they were never used, so remove them instead of repairing them.
2084 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
2085 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
2086 Previously, this ceilinged at INT_MAX, but that doesn't work on
2088 (allocate_pseudovector): Don't use EMACS_INT when int would do.
2090 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
2091 (allocate_vectorlike): Check for ptrdiff_t overflow.
2092 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
2093 when a (possibly-narrower) signed value would do just as well.
2094 We prefer using signed arithmetic, to avoid comparison confusion.
2096 * alloc.c: Catch some string size overflows that we were missing.
2097 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
2098 for convenience in STRING_BYTES_MAX.
2099 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
2100 The definition here is exact; the one in lisp.h was approximate.
2101 (allocate_string_data): Check for string overflow. This catches
2102 some instances we weren't catching before. Also, it catches
2103 size_t overflow on (unusual) hosts where SIZE_MAX <= min
2104 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
2105 and ptrdiff_t and EMACS_INT are both 64 bits.
2107 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
2108 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
2109 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
2111 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
2113 * alloc.c (Fmake_string): Check for out-of-range init.
2115 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
2117 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
2119 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
2121 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
2122 xg_get_default_scrollbar_width.
2124 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
2125 (int_gtk_range_get_value): Move to the scroll bar part of the file.
2126 (style_changed_cb): Call update_theme_scrollbar_width and call
2127 x_set_scroll_bar_default_width and xg_frame_set_char_size for
2128 all frames (Bug#8505).
2129 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
2130 Call gtk_window_set_resizable if HAVE_GTK3.
2131 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
2132 and height if HAVE_GTK3 (Bug#8505).
2133 (scroll_bar_width_for_theme): New variable.
2134 (update_theme_scrollbar_width): New function.
2135 (xg_get_default_scrollbar_width): Move code to
2136 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
2137 (xg_initialize): Call update_theme_scrollbar_width.
2139 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
2141 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
2143 2011-06-12 Martin Rudalics <rudalics@gmx.at>
2145 * frame.c (make_frame): Call other_buffer_safely instead of
2148 * window.c (temp_output_buffer_show): Call display_buffer with
2149 second argument Vtemp_buffer_show_specifiers and reset latter
2150 immediately after the call.
2151 (Vtemp_buffer_show_specifiers): New variable.
2152 (auto_window_vscroll_p, next_screen_context_lines)
2153 (Vscroll_preserve_screen_position): Remove leading asterisks from
2156 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
2158 Fix minor problems found by GCC 4.6.0 static checking.
2159 * buffer.c (Qclone_number): Remove for now, as it's unused.
2160 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
2161 (record_buffer): Remove unused local.
2162 * frame.c (other_visible_frames, frame_buffer_list): Now static.
2163 (set_frame_buffer_list): Remove; unused.
2164 * frame.h (other_visible_frames): Remove decl.
2165 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
2166 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
2167 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
2169 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
2170 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
2171 Define only if HAVE_GPM.
2172 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.

2178 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
2179 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
2180 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
2181 the same widths as pointers. This follows up on the 2011-05-06 patch.
2182 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
2183 * xterm.h: Likewise.
2184 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.

2198 * window.c (delete_deletable_window): Re-add.
2199 (Fset_window_configuration): Rewrite to handle dead buffers and
2200 consequently deletable windows.
2201 (window_tree, Fwindow_tree): Remove. Supply functionality in
2203 (compare_window_configurations): Simplify code.
2205 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
2207 * image.c (imagemagick_load_image): Fix type mismatch.
2208 (Fimagemagick_types): Likewise.
2210 * window.h (replace_buffer_in_windows): Declare.
2212 2011-06-11 Martin Rudalics <rudalics@gmx.at>
2214 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
2215 Qclone_number. Remove external declaration of Qdelete_window.
2216 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
2218 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer): Run
2219 Qbuffer_list_update_hook if allowed.

2221 buffer list implementation.
2222 (other_buffer_safely): New function.
2223 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
2224 calls to replace_buffer_in_windows and
2225 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook

2244 declaration of select_count.
2245 (Fnext_window, Fprevious_window): Rewrite doc-strings.
2246 (Fother_window): Move to window.el.
2247 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
2248 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
2249 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
2251 (replace_buffer_in_windows): Implement by calling
2252 Qreplace_buffer_in_windows.
2253 (replace_buffer_in_all_windows): Remove with some functionality

2260 Qrecord_window_buffer.
2261 (keys_of_window): Move binding for other-window to window.el.
2263 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
2265 * dispextern.h (struct image): Replace data member, whose int_val
2266 and ptr_val fields were not used by anything, with a single
2269 * image.c (Fimage_metadata, make_image, mark_image, tiff_load)
2270 (gif_clear_image, gif_load, imagemagick_load_image)

2750 Without this change, the gnutls library would invoke malloc etc.
2751 directly, which causes problems on non-SYNC_INPUT hosts, and which

2776 (xpm_put_color_table_h):
2777 * lisp.h (struct Lisp_Hash_Table):
2778 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
2779 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
2780 for hashes and hash indexes, instead of 'unsigned' and 'int'.
2781 * alloc.c (allocate_vectorlike):
2782 Check for overflow in vector size calculations.
2783 * ccl.c (ccl_driver):
2784 Check for overflow when converting EMACS_INT to int.
2785 * fns.c, image.c: Remove unnecessary static decls that would otherwise
2786 need to be updated by these changes.
2787 * fns.c (make_hash_table, maybe_resize_hash_table):
2788 Check for integer overflow with large hash tables.
2789 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
2790 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
2791 (SXHASH_REDUCE): New macro.
2792 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
2793 Use it instead of discarding useful hash info with large hash values.
2794 (sxhash_float): New function.
2795 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
2796 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
2797 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
2798 Rewrite to use FIXNUM_BITS, as this simplifies things.
2799 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
2800 Adjust signatures to match updated version of code.
2801 (consing_since_gc): Now EMACS_INT, since a single hash table can
2802 use more than INT_MAX bytes.
2804 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
2806 Make it possible to build with GCC-4.6+ -O2 -flto.
2808 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
2810 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
2812 * minibuf.c (get_minibuffer, read_minibuf_unwind):
2813 Call minibuffer-inactive-mode.
2815 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
2817 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
2818 Update dependencies.
2820 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
2822 * data.c (init_data): Remove code for UTS, this system is not
2825 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
2827 Don't force ./temacs to start in terminal mode.
2829 * frame.c (make_initial_frame): Initialize faces in all cases, not
2830 only when CANNOT_DUMP is defined.
2831 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
2833 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
2835 * dispnew.c (add_window_display_history): Use const for the string
2836 pointer. Remove declaration, not needed.
2838 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
2840 Use 'inline', not 'INLINE'.
2841 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
2842 * alloc.c, fontset.c (INLINE): Remove.
2843 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
2844 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
2845 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
2846 * gmalloc.c (register_heapinfo): Use inline unconditionally.
2847 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
2849 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
2851 Make it possible to run ./temacs.
2853 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
2854 syms_of_callproc does the same thing. Remove test for
2855 "initialized", do it in the caller.
2856 * emacs.c (main): Avoid calling set_initial_environment when dumping.
2858 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
2860 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
2861 (read_minibuf): Use get_minibuffer.
2862 (syms_of_minibuf): Use DEFSYM.
2863 (Qmetadata): New var.
2864 * data.c (Qbuffer): Don't make it static.
2865 (syms_of_data): Use DEFSYM.
2867 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
2869 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
2870 (CCL_CODE_MIN): New macro.
2872 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
2874 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
2876 * eval.c (Qdebug): Now static.
2877 * lisp.h (Qdebug): Remove decl. This reverts a part of the
2878 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
2879 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
2881 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
2883 * image.c: Various fixes to ImageMagick code comments.
2884 (Fimagemagick_types): Doc fix.
2886 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
2888 Minor fixes prompted by GCC 4.6.0 warnings.
2890 * xselect.c (converted_selections, conversion_fail_tag): Now static.
2892 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
2893 (x_clipboard_manager_save_all): Move extern decl to ...
2894 * xterm.h: ... here, so that it can be checked for consistency.
2896 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
2898 * xselect.c (x_clipboard_manager_save_frame)
2899 (x_clipboard_manager_save_all): New functions.
2900 (Fx_clipboard_manager_save): Lisp function deleted.
2902 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
2903 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
2905 * xterm.h: Update prototype.
2907 2011-05-28 William Xu <william.xwl@gmail.com>
2909 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
2912 2011-05-28 Jim Meyering <meyering@redhat.com>
2914 Avoid a sign-extension bug in crypto_hash_function.
2915 * fns.c (to_uchar): Define.
2916 (crypto_hash_function): Use it to convert some newly-signed
2917 variables to unsigned, to avoid sign-extension bugs. For example,
2918 without this change, (md5 "truc") would evaluate to
2919 45723a2aff78ff4fff7fff1114760e62 rather than the expected
2920 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
2921 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
2923 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
2925 Integer overflow fixes.
2927 * dbusbind.c: Serial number integer overflow fixes.
2928 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
2929 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
2930 to hold a serial number that is too large for a fixnum.
2931 (Fdbus_method_return_internal, Fdbus_method_error_internal):
2932 Check for serial numbers out of range. Decode any serial number
2933 that was so large that it became a float. (Bug#8722)
2935 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
2936 (Fdbus_call_method, Fdbus_call_method_asynchronously):
2937 Use XFASTINT rather than XUINT when numbers are nonnegative.
2938 (xd_append_arg, Fdbus_method_return_internal):
2939 (Fdbus_method_error_internal): Likewise. Also, for unsigned
2940 arguments, check that Lisp number is nonnegative, rather than
2941 silently wrapping negative numbers around. (Bug#8722)
2942 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
2945 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
2947 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
2949 ccl: add integer overflow checks
2950 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
2951 (IN_INT_RANGE): New macros.
2952 (ccl_driver): Use them to check for integer overflow when
2953 decoding a CCL program. Many of the new checks are whether XINT (x)
2954 fits in int; it doesn't always, on 64-bit hosts. The new version
2955 doesn't catch all possible integer overflows, but it's an
2956 improvement. (Bug#8719)
2958 * alloc.c (make_event_array): Use XINT, not XUINT.
2959 There's no need for unsigned here.
2961 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
2962 This follows up to the 2011-05-06 change that substituted uintptr_t
2963 for EMACS_INT. This case wasn't caught back then.
2965 Rework Fformat to avoid integer overflow issues.
2966 * editfns.c: Include <float.h> unconditionally, as it's everywhere
2967 now (part of C89). Include <verify.h>.
2968 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
2969 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
2970 (Fformat): Avoid the prepass trying to compute sizes; it was only
2971 approximate and thus did not catch overflow reliably. Instead, walk
2972 through the format just once, formatting and computing sizes as we go,
2973 checking for integer overflow at every step, and allocating a larger
2974 buffer as needed. Keep track separately whether the format is
2975 multibyte. Keep only the most-recently calculated precision, rather
2976 than them all. Record whether each argument has been converted to
2977 string. Use EMACS_INT, not int, for byte and char and arg counts.
2978 Support field widths and precisions larger than INT_MAX. Avoid
2979 sprintf's undefined behavior with conversion specifications such as %#d
2980 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
2981 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
2982 formatting out-of-range floating point numbers with int
2985 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
2987 * data.c: Avoid integer truncation in expressions involving floats.
2988 * data.c: Include <intprops.h>.
2989 (arith_driver): When there's an integer overflow in an expression
2990 involving floating point, convert the integers to floating point
2991 so that the resulting value does not suffer from catastrophic
2992 integer truncation. For example, on a 64-bit host (* 4
2993 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
2994 Do not rely on undefined behavior after integer overflow.
2996 merge count_size_as_multibyte, parse_str_to_multibyte
2997 * character.c, character.h (count_size_as_multibyte):
2998 Rename from parse_str_to_multibyte; all uses changed.
2999 Check for integer overflow.
3000 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
3001 since it's now a duplicate of the other. This is more of
3002 a character than a buffer op, so better that it's in character.c.
3003 * fns.c, print.c: Adjust to above changes.
3005 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
3007 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
3009 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
3011 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3012 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
3013 (x_clipboard_manager_save): Now static.
3014 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
3016 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
3017 (crypto_hash_function): Now static.
3018 Fix pointer signedness problems. Avoid unnecessary initializations.
3020 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
3022 * termhooks.h (Vselection_alist): Make it terminal-local.
3024 * terminal.c (create_terminal): Initialize it.
3026 * xselect.c: Support for clipboard managers.
3027 (Vselection_alist): Move to termhooks.h as terminal-local var.
3028 (LOCAL_SELECTION): New macro.
3029 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
3030 (symbol_to_x_atom): Remove gratuitous arg.
3031 (x_handle_selection_request, lisp_data_to_selection_data)
3032 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
3033 (x_own_selection, x_get_local_selection, x_convert_selection):
3034 New arg, specifying work frame. Use terminal-local Vselection_alist.
3035 (some_frame_on_display): Delete unused function.
3036 (Fx_own_selection_internal, Fx_get_selection_internal)
3037 (Fx_disown_selection_internal, Fx_selection_owner_p)
3038 (Fx_selection_exists_p): New optional frame arg.
3039 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
3040 (x_handle_selection_clear): Don't treat other terminals with the
3041 same keyboard specially. Use the terminal-local Vselection_alist.
3042 (x_clear_frame_selections): Use Frun_hook_with_args.
3044 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
3046 * xterm.h: Add support for those atoms.
3048 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
3050 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
3051 (converted_selections, conversion_fail_tag): New global variables.
3052 (x_selection_request_lisp_error): Free the above.
3053 (x_get_local_selection): Remove unnecessary code.
3054 (x_reply_selection_request): Args changed; handle arbitrary array
3055 of converted selections stored in converted_selections.
3056 Separate the XChangeProperty and SelectionNotify steps.
3057 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
3058 (x_convert_selection): New function.
3059 (x_handle_selection_event): Simplify.
3060 (x_get_foreign_selection): Don't ignore incoming requests while
3061 waiting for an answer; this will fail when we implement
3062 SAVE_TARGETS, and seems unnecessary anyway.
3063 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
3064 (Vx_sent_selection_functions): Doc fix.
3066 2011-05-26 Leo Liu <sdl.web@gmail.com>
3068 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
3070 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3072 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
3074 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
3075 for fringe update if it has periodic bitmap.
3076 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
3077 and fringe_bitmap_periodic_p.
3079 * fringe.c (get_fringe_bitmap_data): New function.
3080 (draw_fringe_bitmap_1, update_window_fringes): Use it.
3081 (update_window_fringes): Record periodicity of fringe bitmap in glyph
3082 row. Mark glyph row for fringe update if periodicity changed.
3084 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
3085 for fringe update unless it has periodic bitmap.
3087 2011-05-25 Kenichi Handa <handa@m17n.org>
3089 * xdisp.c (get_next_display_element): Set correct it->face_id for
3090 a static composition.
3092 2011-05-24 Leo Liu <sdl.web@gmail.com>
3095 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
3097 * fns.c (crypto_hash_function, Fsha1): New function.
3098 (Fmd5): Use crypto_hash_function.
3099 (syms_of_fns): Add Ssha1.
3101 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3103 * gnutls.c: Remove unused macros.
3104 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
3105 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
3106 Remove macros that are defined and never used.
3107 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
3109 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3111 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
3112 (Fx_get_selection_internal): Minor cleanup.
3113 (Fx_own_selection_internal): Rename arguments for consistency with
3116 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3118 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
3120 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3122 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
3124 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3126 * dispnew.c (scrolling_window): Don't exclude the case that the
3127 last enabled row in the desired matrix touches the bottom boundary.
3129 2011-05-21 Glenn Morris <rgm@gnu.org>
3131 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
3132 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
3133 and add some more files.
3135 2011-05-20 Eli Zaretskii <eliz@gnu.org>
3137 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
3138 report_file_error introduced by the change from 2011-05-07.
3140 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
3142 * systime.h (Time): Define only if emacs is defined.
3143 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
3144 where the include path doesn't have X11/X.h by default. See
3145 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
3147 2011-05-20 Kenichi Handa <handa@m17n.org>
3149 * composite.c (find_automatic_composition): Fix previous change.
3151 2011-05-20 Glenn Morris <rgm@gnu.org>
3153 * lisp.mk: New file, split from Makefile.in.
3154 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
3155 (shortlisp): Remove.
3156 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
3158 2011-05-19 Glenn Morris <rgm@gnu.org>
3160 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
3161 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
3162 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
3163 (lisp): Set the order to that of loadup.el.
3164 (shortlisp): Make it a copy of $lisp.
3165 (SOME_MACHINE_LISP): Remove.
3166 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
3167 Use just $shortlisp, not $SOME_MACHINE_LISP too.
3169 2011-05-18 Kenichi Handa <handa@m17n.org>
3171 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
3172 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
3173 (find_automatic_composition): Mostly rewrite for efficiency.
3175 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
3177 * makefile.w32-in: Update dependencies.
3179 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
3181 * menu.c: Include limits.h (fixes the MS-Windows build broken by
3182 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
3184 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
3186 Fix some integer overflow issues, such as string length overflow.
3188 * insdel.c (count_size_as_multibyte): Check for string overflow.
3190 * character.c (lisp_string_width): Check for string overflow.
3191 Use EMACS_INT, not int, for string indexes and lengths; in
3192 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
3193 the resulting string length overflows an EMACS_INT; instead,
3194 report a string overflow if no precision given. When checking for
3195 precision exhaustion, use a check that cannot possibly have
3196 integer overflow. (Bug#8675)
3197 * character.h (lisp_string_width): Adjust to new signature.
3199 * alloc.c (string_overflow): New function.
3200 (Fmake_string): Use it. This doesn't change behavior, but saves
3201 a few bytes and will simplify future changes.
3202 * character.c (string_escape_byte8): Likewise.
3203 * lisp.h (string_overflow): New decl.
3205 Fixups, following up to the user-interface timestamp change.
3206 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
3207 for UI timestamps, instead of unsigned long.
3208 * msdos.c (mouse_get_pos): Likewise.
3209 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
3210 * w32gui.h (Time): Define by including "systime.h" rather than by
3211 declaring it ourselves. (Bug#8664)
3213 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
3214 * image.c (clear_image_cache): Likewise.
3216 * term.c (term_mouse_position): Don't assume time_t wraparound.
3218 Be more systematic about user-interface timestamps.
3219 Before, the code sometimes used 'Time', sometimes 'unsigned long',
3220 and sometimes 'EMACS_UINT', to represent these timestamps.
3221 This change causes it to use 'Time' uniformly, as that's what X uses.
3222 This makes the code easier to follow, and makes it easier to catch
3223 integer overflow bugs such as Bug#8664.
3224 * frame.c (Fmouse_position, Fmouse_pixel_position):
3225 Use Time, not unsigned long, for user-interface timestamps.
3226 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
3227 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
3228 * keyboard.h (last_event_timestamp): Likewise.
3229 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
3230 * menu.h (xmenu_show): Likewise.
3231 * term.c (term_mouse_position): Likewise.
3232 * termhooks.h (struct input_event.timestamp): Likewise.
3233 (struct terminal.mouse_position_hook): Likewise.
3234 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
3235 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
3236 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
3237 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
3239 * menu.h, termhooks.h: Include "systime.h", for Time.
3241 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
3242 Don't assume that the difference between two unsigned long values
3243 can fit into an integer. At this point, we know button_down_time
3244 <= event->timestamp, so the difference must be nonnegative, so
3245 there's no need to cast the result if double-click-time is
3246 nonnegative, as it should be; check that it's nonnegative, just in
3247 case. This bug is triggered when events are more than 2**31 ms
3248 apart (about 25 days). (Bug#8664)
3250 * xselect.c (last_event_timestamp): Remove duplicate decl.
3251 (x_own_selection): Remove needless cast to unsigned long.
3253 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
3254 that always fit in int. Use a sentinel instead of a counter, to
3255 avoid a temp and to allay GCC's concerns about possible int overflow.
3256 * frame.h (struct frame): Use int for menu_bar_items_used
3257 instead of EMACS_INT, since it always fits in int.
3259 * menu.c (grow_menu_items): Check for int overflow.
3261 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
3263 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
3264 Before, the code was not consistent. These values cannot exceed
3265 2**31 - 1 so there's no need to make them unsigned.
3266 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
3267 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
3268 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
3270 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
3272 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
3273 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
3274 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
3275 presumably because the widths might not match.
3277 * window.c (size_window): Avoid needless test at loop start.
3279 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
3281 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
3283 2011-05-12 Drew Adams <drew.adams@oracle.com>
3285 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
3287 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3289 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
3290 `width' to `bar_area_x' and `bar_area_width', respectively.
3291 (x_scroll_run): Take account of fringe background extension.
3293 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
3294 Rename local vars `left' and `width' to `bar_area_x' and
3295 `bar_area_width', respectively.
3296 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
3297 background extension.
3299 2011-05-10 Jim Meyering <meyering@redhat.com>
3301 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
3303 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
3305 * image.c (Finit_image_library): Return t for built-in image types,
3306 like pbm and xbm. (Bug#8640)
3308 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
3310 * w32menu.c (set_frame_menubar): Fix submenu allocation.
3312 2011-05-07 Eli Zaretskii <eliz@gnu.org>
3314 * w32console.c (Fset_screen_color): Doc fix.
3315 (Fget_screen_color): New function.
3316 (syms_of_ntterm): Defsubr it.
3318 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
3319 unlink the temporary file if Fcall_process didn't create it in the
3321 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
3322 child process will be redirected to a file specified with `:file'.
3323 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
3324 cue to call_process_cleanup not to close that handle.
3326 2011-05-07 Ben Key <bkey76@gmail.com>
3328 * makefile.w32-in: The bootstrap-temacs rule now makes use of
3329 one of two shell specific rules, either bootstrap-temacs-CMD or
3330 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
3331 to the previous implementation of the bootstrap-temacs rule.
3332 The bootstrap-temacs-CMD rule is similar to the previous
3333 implementation of the bootstrap-temacs rule except that it
3334 makes use of the ESC_CFLAGS variable instead of the CFLAGS
3337 These changes, along with some changes to nt/configure.bat,
3338 nt/gmake.defs, and nt/nmake.defs, are required to extend my
3339 earlier fix to add support for --cflags and --ldflags options
3340 that include quotes so that it works whether make uses cmd or
3343 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
3345 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
3346 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
3348 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
3349 a string. Handle both cases.
3350 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
3351 (Fdbus_register_method): Use Qinvalid_function.
3353 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3355 * makefile.w32-in: Update dependencies.
3356 (LISP_H): Add inttypes.h and stdin.h.
3357 (PROCESS_H): Add unistd.h.
3359 2011-05-06 Eli Zaretskii <eliz@gnu.org>
3361 * lread.c: Include limits.h (fixes the MS-Windows build broken by
3362 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
3364 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
3366 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
3368 * term.c (vfatal): Remove stray call to va_end.
3369 It's not needed and the C Standard doesn't allow it here anyway.
3371 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
3372 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
3374 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
3377 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
3379 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3381 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
3383 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
3385 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
3387 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
3388 * charset.c (Fdefine_charset_internal): Don't initialize
3389 charset.code_space[15]. The value was garbage, on hosts with
3390 32-bit int (Bug#8600).
3392 * lread.c (read_integer): Be more consistent with string-to-number.
3393 Use string_to_number to do the actual conversion; this avoids
3394 rounding errors and fixes some other screwups. Without this fix,
3395 for example, #x1fffffffffffffff was misread as -2305843009213693952.
3396 (digit_to_number): Move earlier, for benefit of read_integer.
3397 Return -1 if the digit is out of range for the base, -2 if it is
3398 not a digit in any supported base. (Bug#8602)
3400 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
3402 * dispnew.c (scrolling_window): Return 1 if we scrolled,
3403 to match comment at start of function. This also removes a
3404 GCC warning about overflow in a 32+64-bit port.
3406 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
3408 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
3409 Reported by Stefan Monnier in
3410 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
3411 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3412 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
3414 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
3415 (EMACS_UINTPTR): Likewise, with uintptr_t.
3417 * lisp.h: Prefer 64-bit EMACS_INT if available.
3418 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
3419 on 32-bit hosts that have 64-bit int, so that they can access
3421 However, temporarily disable this change unless the temporary
3422 symbol WIDE_EMACS_INT is defined.
3424 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
3426 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
3427 This removes an assumption that EMACS_INT and long are the same
3428 width as pointers. The assumption is true for Emacs porting targets
3429 now, but we want to make other targets possible.
3430 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
3431 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
3432 In the rest of the code, change types of integers that hold casted
3433 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
3434 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
3435 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
3436 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
3437 No need to cast type when ORing.
3438 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
3439 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
3440 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
3441 assume EMACS_INT is the same width as char *.
3442 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
3443 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
3444 Remove no-longer-needed casts.
3445 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
3446 (xg_tool_bar_help_callback, xg_make_tool_item):
3447 Use EMACS_INTPTR to hold an integer
3448 that will be cast to void *; this can avoid a GCC warning
3449 if EMACS_INT is not the same width as void *.
3450 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
3451 * xdisp.c (display_echo_area_1, resize_mini_window_1):
3452 (current_message_1, set_message_1):
3453 Use a local to convert to proper width without a cast.
3454 * xmenu.c (dialog_selection_callback): Likewise.
3456 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
3457 Also, don't assume VALBITS / RAND_BITS is less than 5,
3458 and don't rely on undefined behavior when shifting a 1 left into
3460 * lisp.h (get_random): Change signature to match.
3462 * lread.c (hash_string): Use size_t, not int, for hash computation.
3463 Normally we prefer signed values; but hashing is special, because
3464 it's better to use unsigned division on hash table sizes so that
3465 the remainder is nonnegative. Also, size_t is the natural width
3466 for hashing into memory. The previous code used 'int', which doesn't
3467 retain enough info to hash well into very large tables.
3468 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
3470 * dbusbind.c: Don't possibly lose pointer info when converting.
3471 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3472 Use XPNTR rather than XHASH, so that the high-order bits of
3473 the pointer aren't lost when converting through void *.
3475 * eval.c (Fautoload): Don't double-shift a pointer.
3477 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
3479 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3481 * gnutls.c (DEF_GNUTLS_FN):
3482 * image.c (DEF_IMGLIB_FN): Make function pointers static.
3484 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
3486 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
3489 2011-05-05 Eli Zaretskii <eliz@gnu.org>
3491 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
3492 New version that can reserve upto 2GB of heap space.
3494 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
3496 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
3498 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
3500 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
3501 `gnutls_certificate_set_x509_key_file'.
3503 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
3505 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
3506 Update dependencies.
3508 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3510 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
3511 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
3512 Remove unused parameter `fildes'.
3513 * process.c (read_process_output, send_process): Don't pass it.
3515 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3517 Fix previous change: the library cache is defined in w32.c.
3518 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
3519 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
3521 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3523 Implement dynamic loading of GnuTLS on Windows.
3525 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
3526 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
3527 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
3530 * gnutls.c (Qgnutls_dll): Define.
3531 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
3532 (gnutls_*): Declare function pointers.
3533 (init_gnutls_functions): New function to initialize function pointers.
3534 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
3535 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
3536 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
3537 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
3538 (emacs_gnutls_write, emacs_gnutls_read)
3539 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
3540 (Fgnutls_available_p): New function.
3541 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
3542 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
3543 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
3545 * image.c: Include w32.h.
3546 (Vimage_type_cache): Delete.
3547 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
3548 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
3549 (w32_delayed_load): Move to w32.c.
3551 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
3553 * w32.c (QCloaded_from, Vlibrary_cache): Define.
3554 (w32_delayed_load): Move from image.c. When loading a library, record
3555 its filename in the :loaded-from property of the library id.
3556 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
3557 Initialize and staticpro them.
3558 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
3560 * process.c: Include lisp.h before w32.h, not after.
3561 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
3562 instead of gnutls_record_check_pending.
3564 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
3566 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
3568 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
3569 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
3572 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
3574 * xterm.c (x_set_frame_alpha): Do not set property on anything
3575 else than FRAME_X_OUTER_WINDOW (Bug#8608).
3577 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
3579 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)

3590 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
3591 (Qgnutls_bootprop_callbacks_verify): Make static.
3593 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
3595 * callproc.c: Indentation fixup.
3597 * sysdep.c (wait_for_termination_1): Make static.
3598 (wait_for_termination, interruptible_wait_for_termination):
3599 Move after wait_for_termination_1.
3601 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
3603 * sysdep.c (interruptible_wait_for_termination): New function
3604 which is like wait_for_termination, but allows keyboard
3607 * callproc.c (Fcall_process): Add (:file "file") as an option for
3609 (Fcall_process_region): Ditto.
3611 2011-04-30 Eli Zaretskii <eliz@gnu.org>
3613 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
3614 rather than `XVECTOR (FOO)->size'.
3616 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
3617 inttypes.h, as a gnulib replacement is used if it not available in
3620 2011-04-21 Eli Zaretskii <eliz@gnu.org>
3622 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
3623 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
3624 of MOST_POSITIVE_FIXNUM. (Bug#8528)
3626 * coding.c (coding_alloc_by_realloc): Error out if destination
3627 will grow beyond MOST_POSITIVE_FIXNUM.
3628 (decode_coding_emacs_mule): Abort if there isn't enough place in
3629 charbuf for the composition carryover bytes. Reserve an extra
3630 space for up to 2 characters produced in a loop.
3631 (decode_coding_iso_2022): Abort if there isn't enough place in
3632 charbuf for the composition carryover bytes.
3634 2011-04-21 Eli Zaretskii <eliz@gnu.org>
3636 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
3637 aborting when %lld or %lll format is passed.
3638 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
3639 %llo or %llx format is passed. (Bug#8545)

3644 * doprnt.c (doprnt): Fix the case where a multibyte sequence
3645 produced by %s or %c overflows available buffer space. (Bug#8545)
3647 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
3649 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
3650 (SIZE_MAX): Move defn after all includes, as they might #define it.
3652 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3654 * w32.c (init_environment): Warn about defaulting HOME to C:\.
3656 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3658 * keyboard.c (Qdelayed_warnings_hook): Define.
3659 (command_loop_1): Run `delayed-warnings-hook'
3660 if Vdelayed_warnings_list is non-nil.
3661 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
3662 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
3664 2011-04-28 Eli Zaretskii <eliz@gnu.org>
3666 * doprnt.c (doprnt): Don't return value smaller than the buffer
3667 size if the message was truncated. (Bug#8545).

3674 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3676 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
3678 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
3680 * makefile.w32-in: Update dependencies.
3682 2011-04-27 Eli Zaretskii <eliz@gnu.org>
3684 Improve `doprnt' and its usage. (Bug#8545)
3685 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
3686 `format_end'. Remove support for %l as a conversion specifier.
3687 Don't use xrealloc. Improve diagnostics when the %l size modifier
3688 is used. Update the commentary.
3690 * eval.c (verror): Simplify calculation of size_t.
3692 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
3695 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
3697 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
3700 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3702 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
3703 This makes this file independent of the recent pseudovector change.
3705 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
3707 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
3709 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
3710 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
3711 Remove unused local.
3712 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
3714 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
3715 GCC 4.6.0 optimizes based on type-based alias analysis.
3716 For example, if b is of type struct buffer * and v of type struct
3717 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
3718 != &v->size, and therefore "v->size = 1; b->size = 2; return
3719 v->size;" must therefore return 1. This assumption is incorrect
3720 for Emacs, since it type-puns struct Lisp_Vector * with many other
3721 types. To fix this problem, this patch adds a new type struct
3722 vectorlike_header that documents the constraints on layout of vectors
3723 and pseudovectors, and helps optimizing compilers not get fooled
3724 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
3725 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
3726 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
3728 (XSETPVECTYPE): Rewrite in terms of new macro.
3729 (XSETPVECTYPESIZE): New macro, specifying both type and size.
3730 This is a bit clearer, and further avoids the possibility of
3731 undesirable aliasing.
3732 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
3733 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
3734 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
3735 since Lisp_Subr is a special case (no "next" field).
3736 (ASIZE): Now uses header.size rather than size.
3737 All previous uses of XVECTOR (foo)->size replaced to use this macro,
3738 to avoid the hassle of writing XVECTOR (foo)->header.size.
3739 (struct vectorlike_header): New type.
3740 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
3741 object, to help avoid aliasing.
3742 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
3743 (SUBRP): Likewise, since Lisp_Subr is a special case.
3744 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
3745 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
3746 (struct Lisp_Hash_Table): Combine first two members into a single
3747 struct vectorlike_header member. All uses of "size" and "next" members
3748 changed to be "header.size" and "header.next".
3749 * buffer.h (struct buffer): Likewise.
3750 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
3751 * frame.h (struct frame): Likewise.
3752 * process.h (struct Lisp_Process): Likewise.
3753 * termhooks.h (struct terminal): Likewise.
3754 * window.c (struct save_window_data, struct saved_window): Likewise.
3755 * window.h (struct window): Likewise.
3756 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
3757 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
3758 * buffer.c (init_buffer_once): Likewise.
3759 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
3761 * process.c (Fformat_network_address): Use local var for size,
3764 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
3766 Make the Lisp reader and string-to-float more consistent (Bug#8525)
3767 * data.c (atof): Remove decl; no longer used or needed.
3768 (digit_to_number): Move to lread.c.
3769 (Fstring_to_number): Use new string_to_number function, to be
3770 consistent with how the Lisp reader treats infinities and NaNs.
3771 Do not assume that floating-point numbers represent EMACS_INT
3772 without losing information; this is not true on most 64-bit hosts.
3773 Avoid double-rounding errors, by insisting on integers when
3774 parsing non-base-10 numbers, as the documentation specifies.
3775 * lisp.h (string_to_number): New decl, replacing ...
3776 (isfloat_string): Remove.
3777 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
3778 (read1): Do not accept +. and -. as integers; this
3779 appears to have been a coding error. Similarly, do not accept
3780 strings like +-1e0 as floating point numbers. Do not report
3781 overflow for integer overflows unless the base is not 10 which
3782 means we have no simple and reliable way to continue.
3783 Break out the floating-point parsing into a new
3784 function string_to_number, so that Fstring_to_number parses
3785 floating point numbers consistently with the Lisp reader.
3786 (digit_to_number): Move here from data.c. Make it static inline.
3787 (E_CHAR, EXP_INT): Remove, replacing with ...
3788 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
3789 (string_to_number): New function, replacing isfloat_string.
3790 This function checks for valid syntax and produces the resulting
3791 Lisp float number too. Rework it so that string-to-number
3792 no longer mishandles examples like "1.0e+". Use strtoumax,
3793 so that overflow for non-base-10 numbers is reported only when
3794 there's no portable and simple way to convert to floating point.
3796 * textprop.c (set_text_properties_1): Rewrite for clarity,
3797 and to avoid GCC warning about integer overflow.
3799 * intervals.h (struct interval): Use EMACS_INT for members
3800 where EMACS_UINT might cause problems. See
3801 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
3802 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
3803 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
3805 (offset_intervals): Tell GCC not to worry about length overflow
3806 when negating a negative length.
3808 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
3809 (overrun_check_free): Likewise.
3811 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
3812 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
3815 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3816 (gnutls_make_error): Rename local to avoid shadowing.
3817 (gnutls_emacs_global_deinit): ifdef out; not used.
3818 (Fgnutls_boot): Use const for pointer to readonly storage.
3819 Comment out unused local. Fix pointer signedness problems.
3821 * lread.c (openp): Don't stuff size_t into an 'int'.
3822 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
3823 about possible signed overflow.
3825 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3826 (GDK_KEY_g): Don't define if already defined.
3827 (xg_prepare_tooltip): Avoid pointer signedness problem.
3828 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
3830 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
3831 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
3833 * xfns.c (Fx_window_property): Simplify a bit,
3834 to make a bit faster and to avoid GCC 4.6.0 warning.
3835 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
3837 * fns.c (internal_equal): Don't assume size_t fits in int.
3839 * alloc.c (compact_small_strings): Tighten assertion a little.
3841 Replace pEd with more-general pI, and fix some printf arg casts.
3842 * lisp.h (pI): New macro, generalizing old pEd macro to other
3843 conversion specifiers. For example, use "...%"pI"d..." rather
3844 than "...%"pEd"...".
3845 (pEd): Remove. All uses replaced with similar uses of pI.
3846 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
3847 * alloc.c (check_pure_size): Don't overflow by converting size to int.
3848 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
3849 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
3850 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
3851 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
3852 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
3854 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
3855 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
3856 * print.c (safe_debug_print, print_object): Likewise.
3857 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
3859 Use pI instead of if-then-else-abort. Use %p to avoid casts,
3860 avoiding the 0 flag, which is not portable.
3861 * process.c (Fmake_network_process): Use pI to avoid cast.
3862 * region-cache.c (pp_cache): Likewise.
3863 * xdisp.c (decode_mode_spec): Likewise.
3864 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
3865 behavior on 64-bit hosts with printf arg.
3866 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
3867 (x_stop_queuing_selection_requests): Likewise.
3868 (x_get_window_property): Don't truncate byte count to an 'int'
3871 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
3872 here, since it parses constructs like leading '-' and spaces,
3873 which are not wanted; and it overflows with large numbers.
3874 Instead, simply match F[0-9]+, which is what is wanted anyway.
3876 * alloc.c: Remove unportable assumptions about struct layout.
3877 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
3878 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
3879 (allocate_vectorlike, make_pure_vector): Use the new macros,
3880 plus offsetof, to remove unportable assumptions about struct layout.
3881 These assumptions hold on all porting targets that I know of, but
3882 they are not guaranteed, they're easy to remove, and removing them
3883 makes further changes easier.
3885 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
3886 This doesn't fix a bug but makes the code clearer.
3887 (string_overrun_cookie): Now const. Use initializers that
3888 don't formally overflow signed char, to avoid warnings.
3889 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
3890 can cause Emacs to crash when string overrun checking is enabled.
3891 (allocate_buffer): Don't assume sizeof (struct buffer) is a
3892 multiple of sizeof (EMACS_INT); it need not be, if
3893 alignof(EMACS_INT) < sizeof (EMACS_INT).
3894 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
3896 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
3898 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
3900 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>

3903 supposed to be handshaking. (Bug#8556)
3904 Reported by Paul Eggert <eggert@cs.ucla.edu>.

3916 * alloc.c (check_sblock, check_string_bytes)
3917 (check_string_free_list): Convert to standard C.
3919 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
3921 * w32.c (emacs_gnutls_push): Fix typo.
3923 2011-04-25 Eli Zaretskii <eliz@gnu.org>
3925 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
3926 "cast to pointer from integer of different size".
3928 Improve doprnt and its use in verror. (Bug#8545)
3929 * doprnt.c (doprnt): Document the set of format control sequences
3930 supported by the function. Use SAFE_ALLOCA instead of always
3933 * eval.c (verror): Don't limit the buffer size at size_max-1, that
3934 is one byte too soon. Don't use xrealloc; instead xfree and
3937 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
3939 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
3942 * gnutls.c: Renamed global_initialized to
3943 gnutls_global_initialized. Added internals for the
3944 :verify-hostname-error, :verify-error, and :verify-flags
3945 parameters of `gnutls-boot' and documented those parameters in the
3946 docstring. Start callback support.
3947 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
3948 unless a fatal error occurred. Call gnutls_alert_send_appropriate
3949 on error. Return error code.
3950 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
3951 (emacs_gnutls_read): Likewise.
3952 (Fgnutls_boot): Return handshake error code.
3953 (emacs_gnutls_handle_error): New function.
3954 (wsaerror_to_errno): Likewise.
3956 * w32.h (emacs_gnutls_pull): Add prototype.

4021 * doprnt.c: Include limits.h.
4022 (SIZE_MAX): New macro.
4023 (doprnt): Return a size_t value. 2nd arg is now size_t.
4024 Many local variables are now size_t instead of int or unsigned.
4025 Improve overflow protection. Support `l' modifier for integer
4026 conversions. Support %l conversion. Don't assume an EMACS_INT
4027 argument for integer conversions and for %c.
4029 * lisp.h (doprnt): Restore prototype.
4031 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
4034 * Makefile.in (base_obj): Add back doprnt.o.
4036 * deps.mk (doprnt.o): Add back prerequisites.
4037 (callint.o): Depend on character.h.
4039 * eval.c (internal_lisp_condition_case): Include the handler
4040 representation in the error message.
4041 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
4042 when breaking from the loop.
4044 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
4046 * callint.c (Fcall_interactively): When displaying error message
4047 about invalid control letter, pass the character's codepoint, not
4048 a pointer to its multibyte form. Improve display of the character
4049 in octal and display also its hex code.
4051 * character.c (char_string): Use %x to display the (unsigned)
4052 codepoint of an invalid character, to avoid displaying a bogus
4055 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
4056 `error', not SYMBOL_NAME itself.
4058 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
4059 character arguments to `error'.
4061 * charset.c (check_iso_charset_parameter): Fix incorrect argument
4062 to `error' in error message about FINAL_CHAR argument. Make sure
4063 FINAL_CHAR is a character, and use %c when it is passed as
4064 argument to `error'.
4066 2011-04-23 Eli Zaretskii <eliz@gnu.org>
4068 * s/ms-w32.h (localtime): Redirect to sys_localtime.

4145 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
4146 so that we aren't warned about unused symbols.
4148 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.

4253 * nsfont.m: Fixed bugs in ns_get_family and
4254 ns_descriptor_to_entity that were caused by using free to

4276 (emacs_read, emacs_write): Use it.
4277 * process.c (send_process): Adjust to the new signatures of

4608 * lisp.h: Remove these decls.
4610 * buffer.c (buffer_count): Remove unused var.
4612 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
4613 so that it's not optimized away.
4614 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
4615 * dispextern.h (bidi_dump_cached_states): Remove, since it's
4616 exported only to the debugger.
4618 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
4619 * atimer.h (run_all_atimers): Remove; not exported.
4621 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
4622 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
4623 was inaccessible from Lisp.
4624 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
4625 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
4627 alloc.c: Import and export fewer symbols, and remove unused items.
4628 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
4630 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
4631 it's not optimized away by whole-program optimization.
4632 (message_enable_multibyte, free_misc): Remove.
4633 (catchlist, handlerlist, mark_backtrace):
4634 Declare only if BYTE_MARK_STACK.
4635 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
4636 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
4637 (message_enable_multibyte): Remove decl.
4638 (free_misc, interval_free_list, float_block, float_block_index):
4639 (n_float_blocks, float_free_list, cons_block, cons_block_index):
4640 (cons_free_list, last_marked_index):
4642 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
4643 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
4644 (mark_backtrace): Define only if BYTE_MARK_STACK.
4645 * xdisp.c (message_enable_multibyte): Now static.
4647 Declare Lisp_Object Q* variables to be 'static' if not exported.
4648 This makes it easier for human readers (and static analyzers)
4649 to see whether these variables are used from other modules.
4650 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
4651 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
4652 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

4655 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
4656 * xmenu.c, xselect.c:
4657 Declare Q* vars static if they are not used in other modules.
4658 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
4659 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
4660 Remove decls of unexported vars.
4661 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
4663 * lisp.h (DEFINE_FUNC): Make sname 'static'.
4665 Make Emacs functions such as Fatom 'static' by default.
4666 This makes it easier for human readers (and static analyzers)
4667 to see whether these functions can be called from other modules.
4668 DEFUN now defines a static function. To make the function external
4669 so that it can be used in other C modules, use the new macro DEFUE.
4670 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
4671 (Finit_image_library):
4672 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
4673 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
4674 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
4675 Remove decls, since these functions are now static.
4676 (Funintern, Fget_internal_run_time): New decls, since these functions
4677 were already external.
4679 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
4680 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
4681 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:

4683 * keyboard.c, keymap.c, lread.c:
4684 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
4685 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
4686 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
4687 Mark functions with DEFUE instead of DEFUN,
4688 if they are used in other modules.
4689 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
4690 decls for now-static functions.
4691 * buffer.h (Fdelete_overlay): Remove decl.
4692 * callproc.c (Fgetenv_internal): Mark as internal.
4693 * composite.c (Fremove_list_of_text_properties): Remove decl.

4697 * doc.c (Fdocumntation_property): New forward static decl.
4698 * eval.c (Ffetch_bytecode): New forward static decl.
4699 (Funintern): Remove extern decl; now in .h file where it belongs.
4700 * fileio.c (Fmake_symbolic_link): New forward static decl.
4701 * image.c (Finit_image_library): New forward static decl.

4704 (Fremove_list_of_text_properties): Remove decls.
4705 * keyboard.c (Fthis_command_keys): Remove decl.
4706 (Fcommand_execute): New forward static decl.
4707 * keymap.c (Flookup_key): New forward static decl.
4708 (Fcopy_keymap): Now static.
4709 * keymap.h (Flookup_key): Remove decl.
4710 * process.c (Fget_process): New forward static decl.
4711 (Fprocess_datagram_address): Mark as internal.
4712 * syntax.c (Fsyntax_table_p): New forward static decl.

4718 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
4720 * editfns.c (Fformat): Remove unreachable code.
4722 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
4724 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
4727 2011-04-13 Eli Zaretskii <eliz@gnu.org>
4729 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
4730 when at ZV. (Bug#8487)
4732 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
4734 * charset.c (Fclear_charset_maps): Use xfree instead of free.
4736 * keyboard.c (parse_tool_bar_item): Likewise.
4737 * sound.c (sound_cleanup, alsa_close): Likewise.
4738 * termcap.c (tgetent): Likewise.
4739 * xfns.c (x_default_font_parameter): Likewise.
4740 * xsettings.c (read_and_apply_settings): Likewise.
4742 * alloc.c (overrun_check_malloc, overrun_check_realloc)
4743 (overrun_check_free): Protoize.
4745 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
4747 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
4748 since callers should never pass a negative size.
4749 Change the signature to match that of plain 'read' and 'write'; see
4750 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
4751 * lisp.h: Update prototypes of emacs_write and emacs_read.
4753 2011-04-11 Eli Zaretskii <eliz@gnu.org>
4755 * xdisp.c (redisplay_window): Don't try to determine the character
4756 position of the scroll margin if the window start point w->startp
4757 is outside the buffer's accessible region. (Bug#8468)
4759 2011-04-10 Eli Zaretskii <eliz@gnu.org>
4761 Fix write-region and its subroutines for buffers > 2GB.
4762 * fileio.c (a_write, e_write): Modify declaration of arguments and
4763 local variables to support buffers larger than 2GB.
4764 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
4766 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
4767 argument, local variables, and return value.
4769 * lisp.h: Update prototypes of emacs_write and emacs_read.
4771 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
4773 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
4775 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
4777 Fix more problems found by GCC 4.6.0's static checks.
4779 * xdisp.c (vmessage): Use a better test for character truncation.
4781 * charset.c (load_charset_map): <, not <=, for optimization,
4782 and to avoid potential problems with integer overflow.
4783 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
4784 * casetab.c (set_identity, shuffle): Likewise.
4785 * editfns.c (Fformat): Likewise.
4786 * syntax.c (skip_chars): Likewise.
4788 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
4789 This also lets GCC 4.6.0 generate slightly better loop code.
4791 * callint.c (Fcall_interactively): <, not <=, for optimization.
4792 (Fcall_interactively): Count the number of arguments produced,
4793 not the number of arguments given. This is simpler and lets GCC
4794 4.6.0 generate slightly better code.
4796 * ftfont.c: Distingish more carefully between FcChar8 and char.
4797 The previous code passed unsigned char * to a functions like
4798 strlen and xstrcasecmp that expect char *, which does not
4799 conform to the C standard.
4800 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
4801 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
4802 char * when the C standard requires it.
4804 * keyboard.c (read_char): Remove unused var.
4806 * eval.c: Port to Windows vsnprintf (Bug#8435).
4808 (SIZE_MAX): Define if the headers do not.
4809 (verror): Do not give up if vsnprintf returns a negative count.
4810 Instead, grow the buffer. This ports to Windows vsnprintf, which
4811 does not conform to C99. Problem reported by Eli Zaretskii.
4812 Also, simplify the allocation scheme, by avoiding the need for
4813 calling realloc, and removing the ALLOCATED variable.
4815 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
4817 Remove invocations of doprnt, as Emacs now uses vsnprintf.
4818 But keep the doprint source code for now, as we might revamp it
4819 and use it again (Bug#8435).
4820 * lisp.h (doprnt): Remove.
4821 * Makefile.in (base_obj): Remove doprnt.o.
4822 * deps.mk (doprnt.o): Remove.
4824 error: Print 32- and 64-bit integers portably (Bug#8435).
4825 Without this change, on typical 64-bit hosts error ("...%d...", N)
4826 was used to print both 32- and 64-bit integers N, which relied on
4828 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
4830 * lisp.h (error, verror): Mark as printf-like functions.
4831 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
4832 Report overflow in size calculations when allocating printf buffer.
4833 Do not truncate output string at its first null byte.
4834 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
4835 Truncate the output at a character boundary, since vsnprintf does not
4837 * charset.c (check_iso_charset_parameter): Convert internal
4838 character to string before calling 'error', since %c now has the
4840 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
4841 overflow when computing char to be passed to 'error'. Do not
4842 pass Lisp_Object to 'error'; pass the integer instead.
4843 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
4844 formatted with plain %d.
4846 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
4848 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
4850 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
4852 * xterm.c (x_catch_errors): Remove duplicate declaration.
4854 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
4856 * xdisp.c, lisp.h (message_nolog): Remove; unused.
4858 2011-04-10 Jim Meyering <meyering@redhat.com>
4860 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
4861 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
4862 return ssize_t not "int", and use size_t as the buffer length.
4863 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
4864 * gnutls.h: Update declarations.
4865 * process.c (read_process_output): Use ssize_t, to match.
4866 (send_process): Likewise.
4868 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4870 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
4872 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4874 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
4875 Use unsigned char, to match FcChar8 type definition.
4877 * xterm.c (handle_one_xevent):
4878 * xmenu.c (create_and_show_popup_menu):
4879 * xselect.c (x_decline_selection_request)
4880 (x_reply_selection_request): Avoid type-punned deref of X events.
4882 2011-04-09 Eli Zaretskii <eliz@gnu.org>
4884 Fix some uses of `int' instead of EMACS_INT.
4885 * search.c (string_match_1, fast_string_match)
4886 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
4887 (scan_buffer, find_next_newline_no_quit)
4888 (find_before_next_newline, search_command, Freplace_match)
4889 (Fmatch_data): Make some `int' variables be EMACS_INT.
4891 * xdisp.c (display_count_lines): 3rd argument and return value now
4892 EMACS_INT. All callers changed.
4893 (pint2hrstr): Last argument is now EMACS_INT.
4895 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
4896 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
4897 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
4898 (decode_coding_utf_16, decode_coding_emacs_mule)
4899 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
4900 (decode_coding_ccl, decode_coding_charset)
4901 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
4902 (decode_coding_iso_2022, decode_coding_emacs_mule)
4903 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
4904 <char_offset, last_offset>: Declare EMACS_INT.
4905 (encode_coding_utf_8, encode_coding_utf_16)
4906 (encode_coding_emacs_mule, encode_invocation_designation)
4907 (encode_designation_at_bol, encode_coding_iso_2022)
4908 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
4909 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
4911 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
4912 (encode_invocation_designation): Last argument P_NCHARS is now
4914 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
4915 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
4917 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
4920 * ccl.c (Fccl_execute_on_string): Declare some variables
4923 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
4925 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
4927 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>

4931 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
4933 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
4935 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
4937 * keyboard.c (read_char): Call Lisp function help-form-show,
4938 instead of using internal_with_output_to_temp_buffer.
4939 (Qhelp_form_show): New var.
4940 (syms_of_keyboard): Use DEFSYM macro.
4942 * print.c (internal_with_output_to_temp_buffer): Function deleted.
4944 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
4946 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
4948 * process.c (Flist_processes): Remove to Lisp.
4949 (list_processes_1): Delete.
4951 2011-04-06 Eli Zaretskii <eliz@gnu.org>
4953 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
4955 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
4957 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
4959 Fix more problems found by GCC 4.6.0's static checks.
4961 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
4963 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
4965 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
4967 * xdisp.c (vmessage): Mark as a printf-like function.
4969 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
4971 * sound.c (sound_warning): Don't crash if arg contains a printf format.
4973 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
4974 printf-like functions.
4975 (tiff_load): Add casts to remove these marks before passing them
4976 to system-supplied API.
4978 * eval.c (Fsignal): Remove excess argument to 'fatal'.
4980 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
4981 This avoids several warnings with gcc -Wstrict-overflow.
4982 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
4983 directly, rather than having caller test rule sign. This avoids
4984 some unnecessary tests.
4985 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
4986 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
4987 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
4989 * xfont.c (xfont_text_extents): Remove var that was set but not used.
4990 (xfont_open): Avoid unnecessary tests.
4992 * composite.c (composition_gstring_put_cache): Use unsigned integer.
4994 * composite.h, composite.c (composition_gstring_put_cache):
4995 Use EMACS_INT, not int, for length.
4997 * composite.h (COMPOSITION_DECODE_REFS): New macro,
4998 breaking out part of COMPOSITION_DECODE_RULE.
4999 (COMPOSITION_DECODE_RULE): Use it.
5000 * composite.c (get_composition_id): Remove unused local vars,
5001 by using the new macro.
5003 * textprop.c (set_text_properties_1): Change while to do-while,
5004 since the condition is always true at first.
5006 * intervals.c (graft_intervals_into_buffer): Mark var as used.
5007 (interval_deletion_adjustment): Return unsigned value.
5010 * process.c (list_processes_1, create_pty, read_process_output):
5011 (exec_sentinel): Remove vars that were set but not used.
5012 (create_pty): Remove unnecessary "volatile"s.
5013 (Fnetwork_interface_info): Avoid possibility of int overflow.

5017 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
5019 * syntax.c (scan_words): Remove var that was set but not used.
5020 (update_syntax_table): Use unsigned instead of int.
5022 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
5023 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
5024 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
5026 * print.c (print_error_message): Avoid int overflow.
5028 * font.c (font_list_entities): Redo for clarity,
5029 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
5031 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
5032 (font_score): Avoid potential overflow in diff calculation.
5034 * fns.c (substring_both): Remove var that is set but not used.
5035 (sxhash): Redo loop for clarity and to avoid wraparound warning.
5037 * eval.c (funcall_lambda): Rename local to avoid shadowing.
5039 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
5040 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
5041 can always succeed if overflow has undefined behavior.
5043 * search.c (boyer_moore, wordify): Remove vars set but not used.
5044 (wordify): Omit three unnecessary tests.
5046 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
5047 All callers changed. This avoids the need for an unused var.
5049 * casefiddle.c (casify_region): Remove var that is set but not used.
5051 * dired.c (file_name_completion): Remove var that is set but not used.
5053 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
5055 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
5056 (Finsert_file_contents): Remove unnecessary code checking fd.
5058 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.

5081 Remove vars that are set but not used.
5083 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
5084 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

5098 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
5099 All callers changed.
5100 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):

5105 that is set but not used.
5107 * print.c (print_object): Remove var that is set but not used.
5109 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
5110 The gnulib version avoids calling malloc in the usual case,
5111 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
5112 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
5113 * filelock.c (current_lock_owner): Likewise.
5114 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
5115 * sysdep.c: Include allocator.h, careadlinkat.h.

5138 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
5139 and thereabouts. All callers changed.
5140 (get_per_char_metric): Remove parameter `f', unused since
5141 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

5160 Add lexical binding.
5162 * window.c (Ftemp_output_buffer_show): New fun.
5163 (Fsave_window_excursion):

5166 * lread.c (lisp_file_lexically_bound_p): New function.
5167 (Fload): Bind Qlexical_binding.
5168 (readevalloop): Remove `evalfun' arg.
5169 Bind Qinternal_interpreter_environment.

5184 * eval.c (Fsetq): Handle lexical vars.
5185 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
5186 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
5187 (FletX, Flet): Obey lexical binding.
5188 (Fcommandp): Handle closures.
5189 (Feval): New `lexical' arg.
5190 (eval_sub): New function extracted from Feval. Use it almost
5191 everywhere where Feval was used. Look up vars in lexical env.
5193 (Ffunctionp): Move from subr.el.
5194 (Ffuncall): Handle closures.
5195 (apply_lambda): Remove `eval_flags'.
5196 (funcall_lambda): Handle closures and new byte-code-functions.
5197 (Fspecial_variable_p): New function.
5198 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
5199 but without exporting it to Lisp.
5201 * doc.c (Fdocumentation, store_function_docstring):
5202 * data.c (Finteractive_form): Handle closures.
5204 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
5207 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
5209 (exec_byte_code): New function extracted from Fbyte_code to handle new

5222 * xdisp.c (SCROLL_LIMIT): New macro.
5223 (try_scrolling): Use it when setting scroll_limit.
5224 Limit scrolling to 100 screen lines.
5225 (redisplay_window): Even when falling back on "recentering",
5226 position point in the window according to scroll-conservatively,
5227 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
5229 (try_scrolling): When point is above the window, allow searching
5230 as far as scroll_max, or one screenful, to compute vertical
5231 distance from PT to the scroll margin position. This prevents
5232 try_scrolling from unnecessarily failing when
5233 scroll-conservatively is set to a value slightly larger than the
5234 window height. Clean up the case of PT below the margin at bottom
5235 of window: scroll_max can no longer be INT_MAX. When aggressive
5236 scrolling is in use, don't let point enter the opposite scroll
5237 margin as result of the scroll.
5238 (syms_of_xdisp) <scroll-conservatively>: Document the
5239 threshold of 100 lines for never-recentering scrolling.

5247 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5248 (redisplay_internal): Remove parameter `preserve_echo_area',
5249 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
5251 * indent.c (Fvertical_motion):
5252 * window.c (window_scroll_pixel_based, Frecenter):
5253 Don't pass `need_y_p' to `move_it_by_lines'.
5255 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
5257 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
5258 steal a few bits to be more compact.
5259 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
5260 Remove unneeded casts.
5262 * bytecode.c (Fbyte_code): CAR and CDR can GC.
5264 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
5266 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
5267 binding" message (bug#7967).
5269 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
5271 Fix more problems found by GCC 4.6.0's static checks.
5273 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
5274 Remove unused local var.
5276 * editfns.c (Fmessage_box): Remove unused local var.
5278 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
5279 (note_mode_line_or_margin_highlight, note_mouse_highlight):
5280 Omit unused local vars.
5281 * window.c (shrink_windows): Omit unused local var.
5282 * menu.c (digest_single_submenu): Omit unused local var.
5283 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
5284 Omit unused local var.
5286 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
5287 Don't assume string length fits in int.

5289 (read_key_sequence): Don't check last_real_key_start redundantly.
5291 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
5292 instead of alloca (Bug#8344).
5294 * eval.c (Fbacktrace): Don't assume nargs fits in int.
5295 (Fbacktrace_frame): Don't assume nframes fits in int.
5297 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

5304 * cm.c (calccost): Turn while-do into do-while, for clarity.
5306 * keyboard.c (syms_of_keyboard): Use the same style as later
5307 in this function when indexing through an array. This also
5308 works around GCC bug 48267.
5310 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
5312 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
5314 * chartab.c (sub_char_table_ref_and_range): Redo for slight
5315 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
5317 * keyboard.c, keyboard.h (num_input_events): Now size_t.
5318 This avoids undefined behavior on integer overflow, and is a bit
5319 more convenient anyway since it is compared to a size_t variable.
5321 Variadic C functions now count arguments with size_t, not int.
5322 This avoids an unnecessary limitation on 64-bit machines, which
5323 caused (substring ...) to crash on large vectors (Bug#8344).
5324 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.

5334 * frame.c (x_set_frame_parameters): Likewise.
5335 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
5336 0 if not found, not -1. All callers changed.
5338 * alloc.c (garbage_collect): Don't assume stack size fits in int.
5339 (stack_copy_size): Now size_t, not int.
5340 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
5342 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
5344 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
5345 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
5346 All callers changed.
5348 * lisp.h (multibyte_char_to_unibyte):

5361 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
5362 don't set the hook to nil, but remove the offending function instead.
5363 (Qcommand_hook_internal): Remove, unused.
5364 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
5365 Vcommand_hook_internal.
5367 * eval.c (enum run_hooks_condition): Remove.
5368 (funcall_nil, funcall_not): New functions.
5369 (run_hook_with_args): Call each function through a `funcall' argument.

5386 * w32.c (_wsa_errlist): Use braces for struct initializers.
5388 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
5389 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.

5459 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
5460 (gap_left, gap_right): Don't call it.
5462 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
5464 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
5465 incurred during fontification.

5517 * w32font.c (w32font_draw): Return number of glyphs.
5518 (w32font_open_internal): Remove unused variable `i'.

5535 * term.c (Fsuspend_tty, Fresume_tty):
5536 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
5537 * window.c (temp_output_buffer_show):
5538 * insdel.c (signal_before_change):
5539 * frame.c (Fhandle_switch_frame):
5540 * fileio.c (Fdo_auto_save):
5541 * emacs.c (Fkill_emacs):
5542 * editfns.c (save_excursion_restore):
5543 * cmds.c (internal_self_insert):
5544 * callint.c (Fcall_interactively):
5545 * buffer.c (Fkill_all_local_variables):
5546 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
5548 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
5549 unconditionnaly since it does the check itself.
5551 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
5553 Fix more problems found by GCC 4.5.2's static checks.
5555 * coding.c (encode_coding_raw_text): Avoid unnecessary test
5556 the first time through the loop, since we know p0 < p1 then.
5557 This also avoids a gcc -Wstrict-overflow warning.
5559 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
5560 leading to a memory leak, possible in functions like
5561 load_charset_map_from_file that can allocate an unbounded number
5562 of objects (Bug#8318).
5564 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
5565 that could (at least in theory) be that large.
5567 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
5568 This is less likely to overflow, and avoids undefined behavior if
5569 overflow does occur. All callers changed. Use strtoul to scan
5570 for the unsigned long integer.
5571 (pint2hrstr): Simplify and tune code slightly.
5572 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
5574 * scroll.c (do_scrolling): Work around GCC bug 48228.
5575 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

5578 This also avoids a warning with gcc -Wstrict-overflow.
5579 (validate_x_resource_name): Simplify count usage.
5580 This also avoids a warning with gcc -Wstrict-overflow.
5582 * fileio.c (Fcopy_file): Report error if fchown or fchmod
5585 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
5587 * process.c (Fmake_network_process): Use socklen_t, not int,
5588 where POSIX says socklen_t is required in portable programs.
5589 This fixes a porting bug on hosts like 64-bit HP-UX, where
5590 socklen_t is wider than int (Bug#8277).
5591 (Fmake_network_process, server_accept_connection):
5592 (wait_reading_process_output, read_process_output):
5595 * process.c: Rename or move locals to avoid shadowing.

5605 Make tparam.h and terminfo.c consistent.
5606 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
5607 Include tparam.h instead, since it declares them.
5608 * cm.h (PC): Remove extern decl; tparam.h now does this.
5609 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
5610 * terminfo.c: Include tparam.h, to check interfaces.
5611 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
5612 (tparam): Adjust signature to match interface in tparam.h;
5613 this removes some undefined behavior. Check that outstring and len
5614 are zero, which they always are with Emacs.
5615 * tparam.h (PC, BC, UP): New extern decls.
5617 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
5618 (xftfont_open): Rename locals to avoid shadowing.
5620 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

5636 (composition_update_it): Mark var as initialized.
5637 (find_automatic_composition): Mark vars as initialized,
5638 with a FIXME (Bug#8290).
5640 character.h: Rename locals to avoid shadowing.
5641 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
5642 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
5643 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
5644 (BUF_DEC_POS): Be more systematic about renaming local temporaries
5647 * textprop.c (property_change_between_p): Remove; unused.
5649 * intervals.c (interval_start_pos): Now static.
5651 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
5653 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
5654 Rename locals to avoid shadowing.
5656 * sound.c (wav_play, au_play, Fplay_sound_internal):
5657 Fix pointer signedness.
5658 (alsa_choose_format): Remove unused local var.
5659 (wav_play): Initialize a variable to 0, to prevent undefined
5660 behavior (Bug#8278).
5662 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
5664 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
5666 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
5667 clobbering (Bug#8298).
5668 * sysdep.c (sys_subshell): Likewise.
5669 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
5671 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
5672 This should get cleaned up, so that child_setup has the
5673 same signature on all platforms.
5675 * callproc.c (call_process_cleanup): Now static.
5676 (relocate_fd): Rename locals to avoid shadowing.
5678 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
5680 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
5681 not to be necessary, and produces flickering.
5683 2011-03-20 Glenn Morris <rgm@gnu.org>
5685 * config.in: Remove file.
5687 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
5689 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
5690 are now in src/globals.h.
5691 (syms_of_minibuf): Remove spurious & from previous change.
5693 2011-03-20 Leo <sdl.web@gmail.com>
5695 * minibuf.c (completing-read-function): New variable.
5696 (completing-read-default): Rename from completing-read.
5697 (completing-read): Call completing-read-function.
5699 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
5701 * xfaces.c (Fx_load_color_file):
5702 Read color file from absolute filename (bug#8250).
5704 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
5706 * makefile.w32-in: Update dependencies.
5708 2011-03-17 Eli Zaretskii <eliz@gnu.org>
5710 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

5717 (sigchld_handler): Now static.
5719 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
5720 That way, the code declares only the vars that it needs.
5721 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
5722 * s/cygwin.h (PTY_ITERATION): Likewise.
5723 * s/darwin.h (PTY_ITERATION): Likewise.

5726 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
5727 * process.c (allocate_pty): Don't declare stb unless it's needed.
5729 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
5730 (CONSTANTLIM): Remove; unused.
5731 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
5732 Define only if needed.
5734 * unexelf.c (unexec): Name an expression,
5735 to avoid gcc -Wbad-function-cast warning.
5736 Use a different way to cause a compilation error if anyone uses
5737 n rather than nn, a way that does not involve shadowing.
5738 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
5740 * deps.mk (unexalpha.o): Remove; unused.
5742 New file unexec.h, the (simple) interface for unexec (Bug#8267).
5743 * unexec.h: New file.
5744 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
5745 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
5747 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
5748 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
5749 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.

5757 Rename locals to avoid shadowing.
5759 * lread.c (read1): Rewrite so as not to use empty "else".
5760 (Fload, readevalloop, read1): Rename locals to avoid shadowing.
5762 * print.c (Fredirect_debugging_output): Fix pointer signedess.
5764 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
5765 warning when compiling print.c.
5767 * font.c (font_unparse_fcname): Abort in an "impossible" situation
5768 instead of using an uninitialized var.
5769 (font_sort_entities): Mark var as initialized.
5771 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
5773 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

5805 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
5806 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
5807 some of which prompt warnings from gcc -Wbad-function-cast.
5808 (Fformat_time_string, Fencode_time, Finsert_char):
5809 (Ftranslate_region_internal, Fformat):
5810 Rename or remove local vars to avoid shadowing.

5820 gcc -Wbad-function-cast warning.
5821 (default_value, arithcompare, arith_driver, arith_error): Now static.

5828 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
5829 Rename locals to avoid shadowing.
5830 (mark_stack): Move local variables into the #ifdef region where
5832 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
5833 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
5835 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
5836 (GC_STRING_CHARS): Remove; not used.
5837 (Fmemory_limit): Cast sbrk's returned value to char *.
5839 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
5840 avoids undefined behavior in theory.
5842 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
5844 Use functions, not macros, for up- and down-casing (Bug#8254).
5845 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5846 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
5847 to use the following functions instead of these macros.
5848 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
5849 EMACS_INT, since callers assume the returned value fits in int.
5850 (upcase1): Likewise, for UPCASE_TABLE.
5851 (uppercasep, lowercasep, upcase): New static inline functions.
5852 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

5857 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
5858 (regex_compile, re_search_2, re_match_2_internal):
5859 Remove unused local vars.
5860 (FREE_VAR): Rewrite so as not to use empty "else",
5861 which gcc can warn about.
5862 (regex_compile, re_match_2_internal): Mark locals as initialized.
5863 (RETALLOC_IF): Define only if needed.
5864 (WORDCHAR_P): Likewise. This one is never needed, but is used
5865 only in a comment talking about a compiler bug, so put inside
5866 the #if 0 of that comment.
5867 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
5868 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
5871 * search.c (boyer_moore): Rename locals to avoid shadowing.
5872 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
5873 (PREV_CHAR_BOUNDARY): Likewise.
5875 * search.c (simple_search): Remove unused var.
5877 * dired.c (compile_pattern): Move decl from here ...

5881 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
5883 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
5885 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):

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