5 (Fset_keymap_parent): Simplify.
6 (fix_submap_inheritance): Remove.
7 (access_keymap_1): New function extracted from access_keymap to handle

21
22 2011-07-01 Glenn Morris <rgm@gnu.org>
23
24 * Makefile.in (SETTINGS_LIBS): Fix typo.
25
26 2011-07-01 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny patch)
27
28 * coding.c (Fencode_coding_string): Record the last coding system
29 used, as the function doc string says (bug#8738).
30
31 2011-07-01 Jan Djärv <jan.h.d@swipnet.se>
32
33 * xsettings.c (store_monospaced_changed): Take new font as arg and
34 check for change against current_mono_font.
35 (EMACS_TYPE_SETTINGS): Remove this and related defines.
36 (emacs_settings_constructor, emacs_settings_get_property)
37 (emacs_settings_set_property, emacs_settings_class_init)
38 (emacs_settings_init, gsettings_obj): Remove.
39 (something_changedCB): New function for HAVE_GSETTINGS.
40 (something_changedCB): HAVE_GCONF: Call store_monospaced_changed
41 with value as argument.
42 (init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
43 g_settings_new (Bug#8967). Do not create gsettings_obj.

46
47 * xgselect.c: Add defined (HAVE_GSETTINGS).
48 (xgselect_initialize): Ditto.
49
50 * process.c: Add defined (HAVE_GSETTINGS) for xgselect.h

53
54 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
55
56 * eval.c (struct backtrace): Simplify and port the data structure.
57 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
58 signed bit field, as this assumption is not portable and it makes
59 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
60 "char debug_on_exit : 1" as this is not portable either; instead,
61 use the portable "unsigned int debug_on_exit : 1". Remove unused
62 member evalargs. Remove obsolete comments about cc bombing out.
63
64 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

136 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
137 and use min_width/height from frames size_hint to set
138 min_width/height (Bug#8919).
139
140 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.

157
158 Use gnulib's dup2 module instead of rolling our own.

247
248 * lread.c: Integer overflow fixes.
249 (read_integer): Radix is now EMACS_INT, not int,
250 to improve quality of diagnostics for out-of-range radices.
251 Calculate buffer size correctly for out-of-range radices.

253 read-circle numbers.
254 (read_escape): Avoid int overflow.
255 (Fload, openp, read_buffer_size, read1)

271
272 2011-06-22 Leo Liu <sdl.web@gmail.com>
273
274 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
275 Move to minibuffer.el.
276
277 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
278
279 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
280 The following patches are for when GLYPH_DEBUG && !XASSERT.
281 * dispextern.h (trace_redisplay_p, dump_glyph_string):
282 * dispnew.c (flush_stdout):
283 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
284 Mark as externally visible.
285 * dispnew.c (check_window_matrix_pointers): Now static.
286 * dispnew.c (window_to_frame_vpos):
287 * xfns.c (unwind_create_frame):

289 * scroll.c (CHECK_BOUNDS):
290 * xfaces.c (cache_fache): Rename local to avoid shadowing.
291 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
292 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
293 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
294 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
295 Now static.
296 (debug_method_add): Use va_list and vsprintf rather than relying
297 on undefined behavior with wrong number of arguments.
298 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
299 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
300 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
301 since we're not interested in debugging glyphs with old libraries.
302 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
303 GCC 4.6.0's static checking.
304
305 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
306

319 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
320 (.bitmaps_last):
321 * xfaces.c (load_pixmap):
322 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
323 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
324 (.bitmaps_last, struct x_output.icon_bitmap):
325 Use ptrdiff_t, not int, for bitmap indexes.
326 (x_allocate_bitmap_record): Check for size overflow.

341
342 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
343
344 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
345 (x_session_initialize): Do not assume string length fits in int.
346
347 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
348 This is unlikely, but can occur if DPI is outlandish.
349
350 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
351 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

367 (display_mode_element): Don't assume strlen fits in int.
368

387
388 * filelock.c: Fix some buffer overrun and integer overflow issues.
389 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
390 Reformulate so as not to need the command string.

392 (lock_info_type, lock_file_1, lock_file):
393 Don't assume pid_t and time_t fit in unsigned long.
394 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
395 (current_lock_owner): Prefer signed type for sizes.
396 Use memcpy, not strncpy, where memcpy is what is really wanted.
397 Don't assume (via atoi) that time_t and pid_t fit in int.
398 Check for time_t and/or pid_t out of range, e.g., via a network share.
399 Don't alloca where an auto var works fine.
400
401 * fileio.c: Fix some integer overflow issues.
402 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
403 Don't assume string length fits in int.
404 (directory_file_name): Don't assume string length fits in long.

408 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
409

426 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
427
428 * lread.c (invalid_syntax): Omit length argument.
429 All uses changed. This doesn't fix a bug, but it simplifies the
430 code away from its former Hollerith-constant appearance, and it's
431 one less 'int' to worry about when looking at integer-overflow issues.
432 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
433
434 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
435 This didn't break anything, but it didn't help either.
436 It's confusing to put a bogus integer in a place where the actual
437 value does not matter.
438 (LIST_END_P): Remove unused macro and its bogus comment.
439 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
440
441 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
442 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
443 implementation.
444 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
445 We prefer signed types, and the value cannot exceed the EMACS_INT
446 range anyway (because otherwise the length would not be representable).
447 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
448 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
449 This avoids a GCC warning when WIDE_EMACS_INT.
450
451 * indent.c (sane_tab_width): New function.
452 (current_column, scan_for_column, Findent_to, position_indentation)
453 (compute_motion): Use it. This is just for clarity.
454 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
455
456 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
457
458 * lisp.h (lint_assume): New macro.
459 * composite.c (composition_gstring_put_cache):
460 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
461
462 * editfns.c, insdel.c:
463 Omit unnecessary forward decls, to simplify future changes.
464
465 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
466
467 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
468
469 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
470 Use much-faster test for byte-length change.
471 Don't assume string byte-length fits in 'int'.
472 Check that character arg fits in 'int'.
473 (mapcar1): Declare byte as byte, for clarity.
474
475 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
476
477 * fns.c (concat): Catch string overflow earlier.
478 Do not rely on integer wraparound.
479
480 * dispextern.h (struct it.overlay_strings_charpos)
481 (struct it.selective): Now EMACS_INT, not int.
482 * xdisp.c (forward_to_next_line_start)
483 (back_to_previous_visible_line_start)
484 (reseat_at_next_visible_line_start, next_element_from_buffer):
485 Don't arbitrarily truncate the value of 'selective' to int.
486
487 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
488
489 * composite.c: Don't truncate sizes to 'int'.
490 (composition_gstring_p, composition_reseat_it)
491 (composition_adjust_point): Use EMACS_INT, not int.
492 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
493 not EMACS_UINT, for indexes.
494
495 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
496
497 * buffer.c: Include <verify.h>.
498 (struct sortvec.priority, struct sortstr.priority):
499 Now EMACS_INT, not int.
500 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
501 (struct sortstr.size, record_overlay_string)
502 (struct sortstrlist.size, struct sortlist.used):
503 Don't truncate size to int.
504 (record_overlay_string): Check for size-calculation overflow.
505 (init_buffer_once): Check at compile-time, not run-time.
506
507 2011-06-22 Jim Meyering <meyering@redhat.com>
508
509 Don't leak an XBM-image-sized buffer
510 * image.c (xbm_load): Free the image buffer after using it.
511
512 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
513
514 Port to Sun C.
515 * composite.c (find_automatic_composition): Omit needless 'return 0;'
516 that Sun C diagnosed.
517 * fns.c (secure_hash): Fix pointer signedness issue.
518 * intervals.c (static_offset_intervals): New function.
519 (offset_intervals): Use it.
520
521 2011-06-21 Leo Liu <sdl.web@gmail.com>
522
523 * deps.mk (fns.o):
524 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
525 sha512.h.
526
527 * fns.c (secure_hash): Rename from crypto_hash_function and change
528 the first arg to accept symbols.
529 (Fsecure_hash): New primitive.
530 (syms_of_fns): New symbols.
531
532 2011-06-20 Deniz Dogan <deniz@dogan.se>
533
534 * process.c (Fset_process_buffer): Clarify return value in
535 docstring.
536
537 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
538
539 * dispnew.c (add_window_display_history): Use BVAR.
540
541 * xdisp.c (debug_method_add): Use BVAR.
542 (check_window_end, dump_glyph_matrix, dump_glyph)
543 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
544
545 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
546 Likewise.
547
548 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
549 check till after the cache is created in init_frame_faces.
550
551 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
552
553 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
554
555 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
556
557 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
558 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
559 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
560
561 Improve buffer-overflow checking (Bug#8873).
562 * fileio.c (Finsert_file_contents):
563 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
564 Remove the old (too-loose) buffer overflow checks.
565 They weren't needed, since make_gap checks for buffer overflow.
566 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
567 The old code merely checked for Emacs fixnum overflow, and relied
568 on undefined (wraparound) behavior. The new code avoids undefined
569 behavior, and also checks for ptrdiff_t and/or size_t overflow.
570
571 * editfns.c (Finsert_char): Don't dump core with very negative counts.
572 Tune. Don't use wider integers than needed. Don't use alloca.
573 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
574
575 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
576
577 * insdel.c, lisp.h (buffer_overflow): New function.
578 (insert_from_buffer_1, replace_range, replace_range_2):
579 * insdel.c (make_gap_larger):
580 * editfns.c (Finsert_char):
581 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
582
583 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
584
585 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
586
587 Integer overflow and signedness fixes (Bug#8873).
588
589 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
590 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
591
592 * fileio.c: Don't assume EMACS_INT fits in off_t.
593 (emacs_lseek): New static function.
594 (Finsert_file_contents, Fwrite_region): Use it.
595 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
596
597 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
598
599 * fns.c: Don't overflow int when computing a list length.
600 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
601 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
602 truncation on 64-bit hosts. Check for QUIT every
603 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
604 faster and is responsive enough.
605 (Flength): Report an error instead of overflowing an integer.
606 (Fsafe_length): Return a float if the value is not representable
607 as a fixnum. This shouldn't happen except in contrived situations.
608 (Fnthcdr, Fsort): Don't assume list length fits in int.
609 (Fcopy_sequence): Don't assume vector length fits in int.
610
611 * alloc.c: Check that resized vectors' lengths fit in fixnums.
612 (header_size, word_size): New constants.
613 (allocate_vectorlike): Don't check size overflow here.
614 (allocate_vector): Check it here instead, since this is the only
615 caller of allocate_vectorlike that could cause overflow.
616 Check that the new vector's length is representable as a fixnum.
617
618 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
619 The previous code was bogus. For example, next_almost_prime (32)
620 returned 39, which is undesirable as it is a multiple of 3; and
621 next_almost_prime (24) returned 25, which is a multiple of 5 so
622 why was the code bothering to check for multiples of 7?
623
624 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
625
626 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
627
628 Variadic C functions now count arguments with ptrdiff_t.
629 This partly undoes my 2011-03-30 change, which replaced int with size_t.
630 Back then I didn't know that the Emacs coding style prefers signed int.
631 Also, in the meantime I found a few more instances where arguments
632 were being counted with int, which may truncate counts on 64-bit
633 machines, or EMACS_INT, which may be unnecessarily wide.
634 * lisp.h (struct Lisp_Subr.function.aMANY)
635 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
636 Arg counts are now ptrdiff_t, not size_t.
637 All variadic functions and their callers changed accordingly.
638 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
639 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
640 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
641 * callint.c (Fcall_interactively): Check arg count for overflow,
642 to avoid potential buffer overrun. Use signed char, not 'int',
643 for 'varies' array, so that we needn't bother to check its size
644 calculation for overflow.
645 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
646 * eval.c (apply_lambda):
647 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
648 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
649 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
650
651 * callint.c (Fcall_interactively): Don't use index var as event count.
652
653 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
654 * mem-limits.h (SIZE): Remove; no longer used.
655
656 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
657
658 Remove unnecessary casts.
659 * xterm.c (x_term_init):
660 * xfns.c (x_set_border_pixel):
661 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
662 These aren't needed now that we assume ANSI C.
663
664 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
665 It's more likely to cause problems (due to unsigned overflow)
666 than to cure them.
667
668 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
669
670 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
671
672 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
673
674 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
675
676 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
677
678 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
679
680 GLYPH_CODE_FACE returns EMACS_INT, not int.
681 * dispextern.h (merge_faces):
682 * xfaces.c (merge_faces):
683 * xdisp.c (get_next_display_element, next_element_from_display_vector):
684 Don't assume EMACS_INT fits in int.
685
686 * character.h (CHAR_VALID_P): Remove unused parameter.
687 * fontset.c, lisp.h, xdisp.c: All uses changed.
688
689 * editfns.c (Ftranslate_region_internal): Omit redundant test.
690
691 * fns.c (concat): Minor tuning based on overflow analysis.
692 This doesn't fix any bugs. Use int to hold character, instead
693 of constantly refetching from Emacs object. Use XFASTINT, not
694 XINT, for value known to be a character. Don't bother comparing
695 a single byte to 0400, as it's always less.
696
697 * floatfns.c (Fexpt):
698 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
699
700 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
701 for characters.
702
703 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
704
705 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
706 Without this fix, on a 64-bit host (aset S 0 4294967386) would
707 incorrectly succeed when S was a string, because 4294967386 was
708 truncated before it was used.
709
710 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
711 Otherwise, an out-of-range integer could cause undefined behavior
712 on a 64-bit host.
713
714 * composite.c: Use int, not EMACS_INT, for characters.
715 (fill_gstring_body, composition_compute_stop_pos): Use int, not
716 EMACS_INT, for values that are known to be in character range.
717 This doesn't fix any bugs but is the usual style inside Emacs and
718 may generate better code on 32-bit machines.
719
720 Make sure a 64-bit char is never passed to ENCODE_CHAR.
721 This is for reasons similar to the recent CHAR_STRING fix.
722 * charset.c (Fencode_char): Check that character arg is actually
723 a character. Pass an int to ENCODE_CHAR.
724 * charset.h (ENCODE_CHAR): Verify that the character argument is no
725 wider than 'int', as a compile-time check to prevent future regressions
726 in this area.
727
728 * character.c (char_string): Remove unnecessary casts.
729
730 Make sure a 64-bit char is never passed to CHAR_STRING.
731 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
732 by silently ignoring the top 32 bits, allowing some values
733 that were far too large to be valid characters.
734 * character.h: Include <verify.h>.
735 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
736 arguments are no wider than unsigned, as a compile-time check
737 to prevent future regressions in this area.
738 * data.c (Faset):
739 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
740 (Fsubst_char_in_region):
741 * fns.c (concat):
742 * xdisp.c (decode_mode_spec_coding):
743 Adjust to CHAR_STRING's new requirement.
744 * editfns.c (Finsert_char, Fsubst_char_in_region):
745 * fns.c (concat): Check that character args are actually
746 characters. Without this test, these functions did the wrong
747 thing with wildly out-of-range values on 64-bit hosts.
748
749 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
750 These casts should not be needed on 32-bit hosts, either.
751 * keyboard.c (read_char):
752 * lread.c (Fload): Remove casts to unsigned.
753
754 * lisp.h (UNSIGNED_CMP): New macro.
755 This fixes comparison bugs on 64-bit hosts.
756 (ASCII_CHAR_P): Use it.
757 * casefiddle.c (casify_object):
758 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
759 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
760 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
761 * dispextern.h (FACE_FROM_ID):
762 * keyboard.c (read_char): Use UNSIGNED_CMP.
763
764 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
765 not to EMACS_INT, to avoid GCC warning.
766
767 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
768
769 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
770 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
771 isn't needed on 32-bit machines.
772
773 * buffer.c (Fgenerate_new_buffer_name):
774 Use EMACS_INT for count, not int.
775 (advance_to_char_boundary): Return EMACS_INT, not int.
776
777 * data.c (Qcompiled_function): Now static.
778
779 * window.c (window_body_lines): Now static.
780
781 * image.c (gif_load): Rename local to avoid shadowing.
782
783 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
784 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
785 * alloc.c (make_save_value): Integer argument is now of type
786 ptrdiff_t, not int.
787 (mark_object): Use ptrdiff_t, not int.
788 * lisp.h (pD): New macro.
789 * print.c (print_object): Use it.
790
791 * alloc.c: Use EMACS_INT, not int, to count objects.
792 (total_conses, total_markers, total_symbols, total_vector_size)
793 (total_free_conses, total_free_markers, total_free_symbols)
794 (total_free_floats, total_floats, total_free_intervals)
795 (total_intervals, total_strings, total_free_strings):
796 Now EMACS_INT, not int. All uses changed.
797 (Fgarbage_collect): Compute overall total using a double, so that
798 integer overflow is less likely to be a problem. Check for overflow
799 when converting back to an integer.
800 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
801 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
802 These were 'int' variables that could overflow on 64-bit hosts;
803 they were never used, so remove them instead of repairing them.
804 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
805 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
806 Previously, this ceilinged at INT_MAX, but that doesn't work on
807 64-bit machines.
808 (allocate_pseudovector): Don't use EMACS_INT when int would do.
809
810 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
811 (allocate_vectorlike): Check for ptrdiff_t overflow.
812 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
813 when a (possibly-narrower) signed value would do just as well.
814 We prefer using signed arithmetic, to avoid comparison confusion.
815
816 * alloc.c: Catch some string size overflows that we were missing.
817 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
818 for convenience in STRING_BYTES_MAX.
819 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
820 The definition here is exact; the one in lisp.h was approximate.
821 (allocate_string_data): Check for string overflow. This catches
822 some instances we weren't catching before. Also, it catches
823 size_t overflow on (unusual) hosts where SIZE_MAX <= min
824 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
825 and ptrdiff_t and EMACS_INT are both 64 bits.
826
827 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
828 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
829 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
830
831 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
832
833 * alloc.c (Fmake_string): Check for out-of-range init.
834
835 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
836
837 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
838
839 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
840
841 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
842 xg_get_default_scrollbar_width.
843
844 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
845 (int_gtk_range_get_value): Move to the scroll bar part of the file.
846 (style_changed_cb): Call update_theme_scrollbar_width and call
847 x_set_scroll_bar_default_width and xg_frame_set_char_size for
848 all frames (Bug#8505).
849 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
850 Call gtk_window_set_resizable if HAVE_GTK3.
851 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
852 and height if HAVE_GTK3 (Bug#8505).
853 (scroll_bar_width_for_theme): New variable.
854 (update_theme_scrollbar_width): New function.
855 (xg_get_default_scrollbar_width): Move code to
856 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
857 (xg_initialize): Call update_theme_scrollbar_width.
858
859 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
860
861 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
862
863 2011-06-12 Martin Rudalics <rudalics@gmx.at>
864
865 * frame.c (make_frame): Call other_buffer_safely instead of
866 other_buffer.
867
868 * window.c (temp_output_buffer_show): Call display_buffer with
869 second argument Vtemp_buffer_show_specifiers and reset latter
870 immediately after the call.
871 (Vtemp_buffer_show_specifiers): New variable.
872 (auto_window_vscroll_p, next_screen_context_lines)
873 (Vscroll_preserve_screen_position): Remove leading asterisks from
874 doc-strings.
875
876 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
877
878 Fix minor problems found by GCC 4.6.0 static checking.

1331 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
1332
1333 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
1334 Do not assume that spare memory exists; that assumption is valid
1335 only if SYSTEM_MALLOC.
1336 (LARGE_REQUEST): New macro, so that the issue of large requests
1337 is separated from the issue of spare memory.
1338
1339 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
1340
1341 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

1367 New error handlers.
1368 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
1369 Obey Vx_select_enable_clipboard_manager. Catch errors in
1370 x_clipboard_manager_save (Bug#8779).
1371 (Vx_select_enable_clipboard_manager): New variable.
1372 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
1373
1374 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
1375
1376 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.

1390
1391 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
1392 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
1393 (bidi_cache_search, bidi_cache_iterator_state)
1394 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
1395 (bidi_level_of_next_char, bidi_move_to_visually_next):
1396 Support character positions inside a run of characters covered by a
1397 display string.
1398 (bidi_paragraph_init, bidi_resolve_explicit_1)
1399 (bidi_level_of_next_char): Call bidi_fetch_char and
1400 bidi_fetch_char_advance instead of FETCH_CHAR and
1401 FETCH_CHAR_ADVANCE.
1402 (bidi_init_it): Initialize new members.
1403 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
1404 definitions.
1405 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
1406 instead of using explicit *_CHAR codes.
1407 (bidi_resolve_explicit, bidi_resolve_weak):
1408 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
1409 bidirectional text is supported only in multibyte buffers.
1410 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
1411 it to initialize the frame_window_p member of struct bidi_it.
1412 (bidi_cache_iterator_state, bidi_resolve_explicit_1)

1415 bidi_it->nchars is non-positive.
1416 (bidi_level_of_next_char): Don't try to lookup the cache for the
1417 next/previous character if nothing is cached there yet, or if we
1418 were just reseat()'ed to a new position.
1419
1420 * xdisp.c (set_cursor_from_row): Set start and stop points
1421 according to the row's direction when priming the loop that looks
1422 for the glyph on which to display cursor.
1423 (single_display_spec_intangible_p): Function deleted.
1424 (display_prop_intangible_p): Reimplement to call
1425 handle_display_spec instead of single_display_spec_intangible_p.
1426 Accept 3 additional arguments needed by handle_display_spec.
1427 This fixes incorrect cursor motion across display property with complex
1428 values: lists, `(when COND...)' forms, etc.
1429 (single_display_spec_string_p): Support property values that are
1430 lists with the argument STRING its top-level element.
1431 (display_prop_string_p): Fix the condition for processing a
1432 property that is a list to be consistent with handle_display_spec.
1433 (handle_display_spec): New function, refactored from the
1434 last portion of handle_display_prop.
1435 (compute_display_string_pos): Accept additional argument
1436 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
1437 value of a `display' property is a "replacing spec".
1438 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
1439 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
1440 the display property, but just return a value indicating whether
1441 the display property will replace the characters it covers.
1442 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
1443 frame_window_p members of struct bidi_it.
1444 (compute_display_string_pos, compute_display_string_end):
1445 New functions.
1446 (push_it): Accept second argument POSITION, where pop_it should
1447 jump to continue iteration.
1448 (reseat_1): Initialize bidi_it.disp_pos.
1449
1450 * keyboard.c (adjust_point_for_property): Adjust the call to
1451 display_prop_intangible_p to its new signature.
1452
1453 * dispextern.h (struct bidi_it): New member frame_window_p.
1454 (bidi_init_it): Update prototypes.
1455 (display_prop_intangible_p): Update prototype.
1456 (compute_display_string_pos, compute_display_string_end):
1457 Declare prototypes.
1458 (struct bidi_it): New members nchars and disp_pos. ch_len is now
1459 EMACS_INT.

1465 * lisp.h: Change signatures accordingly.
1466 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
1467 All callers changed. (Bug#8762)
1468
1469 * gnutls.c: Use Emacs's memory allocators.
1470 Without this change, the gnutls library would invoke malloc etc.
1471 directly, which causes problems on non-SYNC_INPUT hosts, and which
1472 runs afoul of improving memory_full behavior. (Bug#8761)
1473 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
1474 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
1475 xfree instead of the default malloc, realloc, free.
1476 (Fgnutls_boot): No need to check for memory allocation failure,
1477 since xmalloc does that for us.
1478
1479 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
1480 * category.c (hash_get_category_set):
1481 * ccl.c (ccl_driver):
1482 * charset.c (Fdefine_charset_internal):
1483 * charset.h (struct charset.hash_index):

1485 (composition_gstring_put_cache):
1486 * composite.h (struct composition.hash_index):

1490 (hashfn_equal, hashfn_user_defined, make_hash_table)
1491 (maybe_resize_hash_table, hash_lookup, hash_put)
1492 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
1493 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
1494 (Fsxhash, Fgethash, Fputhash, Fmaphash):
1495 * image.c (make_image, search_image_cache, lookup_image)
1496 (xpm_put_color_table_h):
1497 * lisp.h (struct Lisp_Hash_Table):
1498 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
1499 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
1500 for hashes and hash indexes, instead of 'unsigned' and 'int'.
1501 * alloc.c (allocate_vectorlike):
1502 Check for overflow in vector size calculations.
1503 * ccl.c (ccl_driver):
1504 Check for overflow when converting EMACS_INT to int.
1505 * fns.c, image.c: Remove unnecessary static decls that would otherwise
1506 need to be updated by these changes.
1507 * fns.c (make_hash_table, maybe_resize_hash_table):
1508 Check for integer overflow with large hash tables.
1509 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
1510 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
1511 (SXHASH_REDUCE): New macro.
1512 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
1513 Use it instead of discarding useful hash info with large hash values.
1514 (sxhash_float): New function.
1515 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
1516 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
1517 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
1518 Rewrite to use FIXNUM_BITS, as this simplifies things.
1519 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
1520 Adjust signatures to match updated version of code.
1521 (consing_since_gc): Now EMACS_INT, since a single hash table can
1522 use more than INT_MAX bytes.
1523
1524 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
1525
1526 Make it possible to build with GCC-4.6+ -O2 -flto.
1527
1528 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
1529
1530 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
1531
1532 * minibuf.c (get_minibuffer, read_minibuf_unwind):
1533 Call minibuffer-inactive-mode.
1534
1535 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
1536
1537 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
1538 Update dependencies.
1539
1540 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1541
1542 * data.c (init_data): Remove code for UTS, this system is not
1543 supported anymore.
1544
1545 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1546
1547 Don't force ./temacs to start in terminal mode.
1548
1549 * frame.c (make_initial_frame): Initialize faces in all cases, not
1550 only when CANNOT_DUMP is defined.
1551 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
1552
1553 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1554
1555 * dispnew.c (add_window_display_history): Use const for the string
1556 pointer. Remove declaration, not needed.
1557
1558 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1559
1560 Use 'inline', not 'INLINE'.
1561 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
1562 * alloc.c, fontset.c (INLINE): Remove.
1563 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
1564 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
1565 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
1566 * gmalloc.c (register_heapinfo): Use inline unconditionally.
1567 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
1568
1569 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1570
1571 Make it possible to run ./temacs.
1572
1573 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
1574 syms_of_callproc does the same thing. Remove test for
1575 "initialized", do it in the caller.
1576 * emacs.c (main): Avoid calling set_initial_environment when dumping.
1577
1578 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
1579
1580 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
1581 (read_minibuf): Use get_minibuffer.
1582 (syms_of_minibuf): Use DEFSYM.
1583 (Qmetadata): New var.
1584 * data.c (Qbuffer): Don't make it static.
1585 (syms_of_data): Use DEFSYM.
1586
1587 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1588
1589 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
1590 (CCL_CODE_MIN): New macro.
1591
1592 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
1593
1594 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
1595
1596 * eval.c (Qdebug): Now static.
1597 * lisp.h (Qdebug): Remove decl. This reverts a part of the
1598 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
1599 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
1600
1601 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1602
1603 * image.c: Various fixes to ImageMagick code comments.
1604 (Fimagemagick_types): Doc fix.
1605
1606 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
1607
1608 Minor fixes prompted by GCC 4.6.0 warnings.
1609
1610 * xselect.c (converted_selections, conversion_fail_tag): Now static.
1611
1612 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
1613 (x_clipboard_manager_save_all): Move extern decl to ...
1614 * xterm.h: ... here, so that it can be checked for consistency.
1615
1616 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1617
1618 * xselect.c (x_clipboard_manager_save_frame)
1619 (x_clipboard_manager_save_all): New functions.
1620 (Fx_clipboard_manager_save): Lisp function deleted.
1621
1622 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.

1624
1625 * xterm.h: Update prototype.
1626

1630 exiting (Bug#8239).
1631
1632 2011-05-28 Jim Meyering <meyering@redhat.com>
1633
1634 Avoid a sign-extension bug in crypto_hash_function.
1635 * fns.c (to_uchar): Define.
1636 (crypto_hash_function): Use it to convert some newly-signed
1637 variables to unsigned, to avoid sign-extension bugs. For example,
1638 without this change, (md5 "truc") would evaluate to
1639 45723a2aff78ff4fff7fff1114760e62 rather than the expected
1640 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
1641 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
1642
1643 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1644
1645 Integer overflow fixes.
1646
1647 * dbusbind.c: Serial number integer overflow fixes.
1648 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
1649 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
1650 to hold a serial number that is too large for a fixnum.
1651 (Fdbus_method_return_internal, Fdbus_method_error_internal):
1652 Check for serial numbers out of range. Decode any serial number
1653 that was so large that it became a float. (Bug#8722)
1654
1655 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
1656 (Fdbus_call_method, Fdbus_call_method_asynchronously):
1657 Use XFASTINT rather than XUINT when numbers are nonnegative.
1658 (xd_append_arg, Fdbus_method_return_internal):
1659 (Fdbus_method_error_internal): Likewise. Also, for unsigned
1660 arguments, check that Lisp number is nonnegative, rather than
1661 silently wrapping negative numbers around. (Bug#8722)
1662 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
1663 (Bug#8722)
1664
1665 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
1666
1667 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
1668
1669 ccl: add integer overflow checks
1670 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
1671 (IN_INT_RANGE): New macros.
1672 (ccl_driver): Use them to check for integer overflow when
1673 decoding a CCL program. Many of the new checks are whether XINT (x)
1674 fits in int; it doesn't always, on 64-bit hosts. The new version
1675 doesn't catch all possible integer overflows, but it's an
1676 improvement. (Bug#8719)
1677
1678 * alloc.c (make_event_array): Use XINT, not XUINT.
1679 There's no need for unsigned here.
1680
1681 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
1682 This follows up to the 2011-05-06 change that substituted uintptr_t
1683 for EMACS_INT. This case wasn't caught back then.
1684
1685 Rework Fformat to avoid integer overflow issues.
1686 * editfns.c: Include <float.h> unconditionally, as it's everywhere
1687 now (part of C89). Include <verify.h>.
1688 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
1689 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
1690 (Fformat): Avoid the prepass trying to compute sizes; it was only
1691 approximate and thus did not catch overflow reliably. Instead, walk
1692 through the format just once, formatting and computing sizes as we go,
1693 checking for integer overflow at every step, and allocating a larger
1694 buffer as needed. Keep track separately whether the format is
1695 multibyte. Keep only the most-recently calculated precision, rather
1696 than them all. Record whether each argument has been converted to
1697 string. Use EMACS_INT, not int, for byte and char and arg counts.
1698 Support field widths and precisions larger than INT_MAX. Avoid
1699 sprintf's undefined behavior with conversion specifications such as %#d
1700 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
1701 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
1702 formatting out-of-range floating point numbers with int
1703 formats. (Bug#8668)
1704
1705 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
1706
1707 * data.c: Avoid integer truncation in expressions involving floats.
1708 * data.c: Include <intprops.h>.
1709 (arith_driver): When there's an integer overflow in an expression
1710 involving floating point, convert the integers to floating point
1711 so that the resulting value does not suffer from catastrophic
1712 integer truncation. For example, on a 64-bit host (* 4
1713 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
1714 Do not rely on undefined behavior after integer overflow.
1715
1716 merge count_size_as_multibyte, parse_str_to_multibyte
1717 * character.c, character.h (count_size_as_multibyte):
1718 Rename from parse_str_to_multibyte; all uses changed.
1719 Check for integer overflow.
1720 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
1721 since it's now a duplicate of the other. This is more of
1722 a character than a buffer op, so better that it's in character.c.
1723 * fns.c, print.c: Adjust to above changes.
1724
1725 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
1726
1727 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
1728
1729 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1730

1737 (crypto_hash_function): Now static.
1738 Fix pointer signedness problems. Avoid unnecessary initializations.
1739

1743
1744 * terminal.c (create_terminal): Initialize it.
1745
1746 * xselect.c: Support for clipboard managers.
1747 (Vselection_alist): Move to termhooks.h as terminal-local var.
1748 (LOCAL_SELECTION): New macro.
1749 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
1750 (symbol_to_x_atom): Remove gratuitous arg.
1751 (x_handle_selection_request, lisp_data_to_selection_data)
1752 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
1753 (x_own_selection, x_get_local_selection, x_convert_selection):
1754 New arg, specifying work frame. Use terminal-local Vselection_alist.
1755 (some_frame_on_display): Delete unused function.
1756 (Fx_own_selection_internal, Fx_get_selection_internal)
1757 (Fx_disown_selection_internal, Fx_selection_owner_p)
1758 (Fx_selection_exists_p): New optional frame arg.
1759 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
1760 (x_handle_selection_clear): Don't treat other terminals with the
1761 same keyboard specially. Use the terminal-local Vselection_alist.
1762 (x_clear_frame_selections): Use Frun_hook_with_args.
1763
1764 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
1765
1766 * xterm.h: Add support for those atoms.
1767
1768 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
1769
1770 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
1771 (converted_selections, conversion_fail_tag): New global variables.
1772 (x_selection_request_lisp_error): Free the above.
1773 (x_get_local_selection): Remove unnecessary code.
1774 (x_reply_selection_request): Args changed; handle arbitrary array
1775 of converted selections stored in converted_selections.
1776 Separate the XChangeProperty and SelectionNotify steps.
1777 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
1778 (x_convert_selection): New function.
1779 (x_handle_selection_event): Simplify.
1780 (x_get_foreign_selection): Don't ignore incoming requests while
1781 waiting for an answer; this will fail when we implement
1782 SAVE_TARGETS, and seems unnecessary anyway.
1783 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
1784 (Vx_sent_selection_functions): Doc fix.
1785
1786 2011-05-26 Leo Liu <sdl.web@gmail.com>
1787
1788 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
1789
1790 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1791
1792 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
1793
1794 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
1795 for fringe update if it has periodic bitmap.
1796 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
1797 and fringe_bitmap_periodic_p.
1798
1799 * fringe.c (get_fringe_bitmap_data): New function.
1800 (draw_fringe_bitmap_1, update_window_fringes): Use it.
1801 (update_window_fringes): Record periodicity of fringe bitmap in glyph
1802 row. Mark glyph row for fringe update if periodicity changed.
1803
1804 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
1805 for fringe update unless it has periodic bitmap.
1806
1807 2011-05-25 Kenichi Handa <handa@m17n.org>
1808
1809 * xdisp.c (get_next_display_element): Set correct it->face_id for
1810 a static composition.
1811
1812 2011-05-24 Leo Liu <sdl.web@gmail.com>
1813
1814 * deps.mk (fns.o):
1815 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
1816
1817 * fns.c (crypto_hash_function, Fsha1): New function.
1818 (Fmd5): Use crypto_hash_function.
1819 (syms_of_fns): Add Ssha1.
1820
1821 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1822
1823 * gnutls.c: Remove unused macros.
1824 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
1825 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
1826 Remove macros that are defined and never used.
1827 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
1828
1829 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1830
1831 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
1832 (Fx_get_selection_internal): Minor cleanup.
1833 (Fx_own_selection_internal): Rename arguments for consistency with
1834 select.el.
1835
1836 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1837
1838 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
1839
1840 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1841
1842 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
1843
1844 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1845
1846 * dispnew.c (scrolling_window): Don't exclude the case that the
1847 last enabled row in the desired matrix touches the bottom boundary.
1848
1849 2011-05-21 Glenn Morris <rgm@gnu.org>
1850
1851 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
1852 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
1853 and add some more files.
1854
1855 2011-05-20 Eli Zaretskii <eliz@gnu.org>
1856
1857 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
1858 report_file_error introduced by the change from 2011-05-07.
1859
1860 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
1861
1862 * systime.h (Time): Define only if emacs is defined.
1863 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
1864 where the include path doesn't have X11/X.h by default. See
1865 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
1866
1867 2011-05-20 Kenichi Handa <handa@m17n.org>
1868
1869 * composite.c (find_automatic_composition): Fix previous change.
1870
1871 2011-05-20 Glenn Morris <rgm@gnu.org>
1872
1873 * lisp.mk: New file, split from Makefile.in.
1874 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
1875 (shortlisp): Remove.
1876 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
1877
1878 2011-05-19 Glenn Morris <rgm@gnu.org>
1879
1880 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
1881 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
1882 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
1883 (lisp): Set the order to that of loadup.el.
1884 (shortlisp): Make it a copy of $lisp.
1885 (SOME_MACHINE_LISP): Remove.
1886 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
1887 Use just $shortlisp, not $SOME_MACHINE_LISP too.
1888
1889 2011-05-18 Kenichi Handa <handa@m17n.org>
1890
1891 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
1892 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
1893 (find_automatic_composition): Mostly rewrite for efficiency.
1894
1895 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
1896
1897 * makefile.w32-in: Update dependencies.
1898
1899 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
1900
1901 * menu.c: Include limits.h (fixes the MS-Windows build broken by
1902 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
1903
1904 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
1905
1906 Fix some integer overflow issues, such as string length overflow.
1907
1908 * insdel.c (count_size_as_multibyte): Check for string overflow.
1909
1910 * character.c (lisp_string_width): Check for string overflow.
1911 Use EMACS_INT, not int, for string indexes and lengths; in
1912 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
1913 the resulting string length overflows an EMACS_INT; instead,
1914 report a string overflow if no precision given. When checking for
1915 precision exhaustion, use a check that cannot possibly have
1916 integer overflow. (Bug#8675)
1917 * character.h (lisp_string_width): Adjust to new signature.
1918
1919 * alloc.c (string_overflow): New function.
1920 (Fmake_string): Use it. This doesn't change behavior, but saves
1921 a few bytes and will simplify future changes.
1922 * character.c (string_escape_byte8): Likewise.
1923 * lisp.h (string_overflow): New decl.
1924
1925 Fixups, following up to the user-interface timestamp change.
1926 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
1927 for UI timestamps, instead of unsigned long.
1928 * msdos.c (mouse_get_pos): Likewise.
1929 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
1930 * w32gui.h (Time): Define by including "systime.h" rather than by
1931 declaring it ourselves. (Bug#8664)
1932
1933 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
1934 * image.c (clear_image_cache): Likewise.
1935
1936 * term.c (term_mouse_position): Don't assume time_t wraparound.
1937
1938 Be more systematic about user-interface timestamps.
1939 Before, the code sometimes used 'Time', sometimes 'unsigned long',
1940 and sometimes 'EMACS_UINT', to represent these timestamps.
1941 This change causes it to use 'Time' uniformly, as that's what X uses.
1942 This makes the code easier to follow, and makes it easier to catch
1943 integer overflow bugs such as Bug#8664.
1944 * frame.c (Fmouse_position, Fmouse_pixel_position):
1945 Use Time, not unsigned long, for user-interface timestamps.
1946 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
1947 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
1948 * keyboard.h (last_event_timestamp): Likewise.
1949 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
1950 * menu.h (xmenu_show): Likewise.
1951 * term.c (term_mouse_position): Likewise.
1952 * termhooks.h (struct input_event.timestamp): Likewise.
1953 (struct terminal.mouse_position_hook): Likewise.
1954 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
1955 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
1956 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
1957 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
1958 what it was before.
1959 * menu.h, termhooks.h: Include "systime.h", for Time.
1960
1961 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
1962 Don't assume that the difference between two unsigned long values
1963 can fit into an integer. At this point, we know button_down_time
1964 <= event->timestamp, so the difference must be nonnegative, so
1965 there's no need to cast the result if double-click-time is
1966 nonnegative, as it should be; check that it's nonnegative, just in
1967 case. This bug is triggered when events are more than 2**31 ms
1968 apart (about 25 days). (Bug#8664)
1969
1970 * xselect.c (last_event_timestamp): Remove duplicate decl.
1971 (x_own_selection): Remove needless cast to unsigned long.
1972
1973 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
1974 that always fit in int. Use a sentinel instead of a counter, to
1975 avoid a temp and to allay GCC's concerns about possible int overflow.
1976 * frame.h (struct frame): Use int for menu_bar_items_used
1977 instead of EMACS_INT, since it always fits in int.
1978
1979 * menu.c (grow_menu_items): Check for int overflow.
1980
1981 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
1982
1983 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
1984 Before, the code was not consistent. These values cannot exceed
1985 2**31 - 1 so there's no need to make them unsigned.
1986 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
1987 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
1988 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
1989 as modifiers.
1990 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
1991
1992 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
1993 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
1994 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
1995 presumably because the widths might not match.
1996
1997 * window.c (size_window): Avoid needless test at loop start.
1998
1999 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
2000
2001 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
2002
2003 2011-05-12 Drew Adams <drew.adams@oracle.com>
2004
2005 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
2006
2007 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2008
2009 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
2010 `width' to `bar_area_x' and `bar_area_width', respectively.
2011 (x_scroll_run): Take account of fringe background extension.
2012
2013 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
2014 Rename local vars `left' and `width' to `bar_area_x' and
2015 `bar_area_width', respectively.
2016 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
2017 background extension.
2018
2019 2011-05-10 Jim Meyering <meyering@redhat.com>
2020
2021 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
2022
2023 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
2024
2025 * image.c (Finit_image_library): Return t for built-in image types,
2026 like pbm and xbm. (Bug#8640)
2027
2028 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
2029
2030 * w32menu.c (set_frame_menubar): Fix submenu allocation.
2031
2032 2011-05-07 Eli Zaretskii <eliz@gnu.org>
2033
2034 * w32console.c (Fset_screen_color): Doc fix.
2035 (Fget_screen_color): New function.
2036 (syms_of_ntterm): Defsubr it.
2037
2038 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
2039 unlink the temporary file if Fcall_process didn't create it in the
2040 first place.
2041 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
2042 child process will be redirected to a file specified with `:file'.
2043 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
2044 cue to call_process_cleanup not to close that handle.
2045
2046 2011-05-07 Ben Key <bkey76@gmail.com>
2047
2048 * makefile.w32-in: The bootstrap-temacs rule now makes use of
2049 one of two shell specific rules, either bootstrap-temacs-CMD or
2050 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
2051 to the previous implementation of the bootstrap-temacs rule.
2052 The bootstrap-temacs-CMD rule is similar to the previous
2053 implementation of the bootstrap-temacs rule except that it
2054 makes use of the ESC_CFLAGS variable instead of the CFLAGS
2055 variable.
2056
2057 These changes, along with some changes to nt/configure.bat,
2058 nt/gmake.defs, and nt/nmake.defs, are required to extend my
2059 earlier fix to add support for --cflags and --ldflags options
2060 that include quotes so that it works whether make uses cmd or
2061 sh as the shell.
2062
2063 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
2064
2065 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
2066 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
2067 is a constant.
2068 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
2069 a string. Handle both cases.
2070 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
2071 (Fdbus_register_method): Use Qinvalid_function.
2072
2073 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
2074
2075 * makefile.w32-in: Update dependencies.
2076 (LISP_H): Add inttypes.h and stdin.h.
2077 (PROCESS_H): Add unistd.h.
2078
2079 2011-05-06 Eli Zaretskii <eliz@gnu.org>
2080
2081 * lread.c: Include limits.h (fixes the MS-Windows build broken by
2082 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
2083
2084 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
2085
2086 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
2087
2088 * term.c (vfatal): Remove stray call to va_end.
2089 It's not needed and the C Standard doesn't allow it here anyway.
2090
2091 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
2092 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
2093
2094 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
2095 bytes.
2096
2097 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
2098
2099 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
2100
2101 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
2102
2103 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
2104
2105 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
2106
2107 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
2108 * charset.c (Fdefine_charset_internal): Don't initialize
2109 charset.code_space[15]. The value was garbage, on hosts with
2110 32-bit int (Bug#8600).
2111
2112 * lread.c (read_integer): Be more consistent with string-to-number.
2113 Use string_to_number to do the actual conversion; this avoids
2114 rounding errors and fixes some other screwups. Without this fix,
2115 for example, #x1fffffffffffffff was misread as -2305843009213693952.
2116 (digit_to_number): Move earlier, for benefit of read_integer.
2117 Return -1 if the digit is out of range for the base, -2 if it is
2118 not a digit in any supported base. (Bug#8602)
2119
2120 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
2121
2122 * dispnew.c (scrolling_window): Return 1 if we scrolled,
2123 to match comment at start of function. This also removes a
2124 GCC warning about overflow in a 32+64-bit port.
2125
2126 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
2127
2128 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
2129 Reported by Stefan Monnier in
2130 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
2131 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2132 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
2133
2134 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
2135 (EMACS_UINTPTR): Likewise, with uintptr_t.
2136
2137 * lisp.h: Prefer 64-bit EMACS_INT if available.
2138 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
2139 on 32-bit hosts that have 64-bit int, so that they can access
2140 large files.
2141 However, temporarily disable this change unless the temporary
2142 symbol WIDE_EMACS_INT is defined.
2143
2144 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
2145
2146 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
2147 This removes an assumption that EMACS_INT and long are the same
2148 width as pointers. The assumption is true for Emacs porting targets
2149 now, but we want to make other targets possible.
2150 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
2151 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
2152 In the rest of the code, change types of integers that hold casted
2153 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
2154 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
2155 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
2156 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
2157 No need to cast type when ORing.
2158 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
2159 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
2160 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
2161 assume EMACS_INT is the same width as char *.
2162 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
2163 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
2164 Remove no-longer-needed casts.
2165 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
2166 (xg_tool_bar_help_callback, xg_make_tool_item):
2167 Use EMACS_INTPTR to hold an integer
2168 that will be cast to void *; this can avoid a GCC warning
2169 if EMACS_INT is not the same width as void *.
2170 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
2171 * xdisp.c (display_echo_area_1, resize_mini_window_1):
2172 (current_message_1, set_message_1):
2173 Use a local to convert to proper width without a cast.
2174 * xmenu.c (dialog_selection_callback): Likewise.
2175
2176 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
2177 Also, don't assume VALBITS / RAND_BITS is less than 5,
2178 and don't rely on undefined behavior when shifting a 1 left into
2179 the sign bit.
2180 * lisp.h (get_random): Change signature to match.
2181
2182 * lread.c (hash_string): Use size_t, not int, for hash computation.
2183 Normally we prefer signed values; but hashing is special, because
2184 it's better to use unsigned division on hash table sizes so that
2185 the remainder is nonnegative. Also, size_t is the natural width
2186 for hashing into memory. The previous code used 'int', which doesn't
2187 retain enough info to hash well into very large tables.
2188 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
2189
2190 * dbusbind.c: Don't possibly lose pointer info when converting.
2191 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2192 Use XPNTR rather than XHASH, so that the high-order bits of
2193 the pointer aren't lost when converting through void *.
2194
2195 * eval.c (Fautoload): Don't double-shift a pointer.
2196
2197 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
2198

2231 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
2232 Remove unused parameter `fildes'.
2233 * process.c (read_process_output, send_process): Don't pass it.

2276 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
2277 Initialize and staticpro them.
2278 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
2279
2280 * process.c: Include lisp.h before w32.h, not after.
2281 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
2282 instead of gnutls_record_check_pending.
2283

2322
2323 * sysdep.c (interruptible_wait_for_termination): New function

2325 interruptions.
2326
2327 * callproc.c (Fcall_process): Add (:file "file") as an option for
2328 the STDOUT buffer.
2329 (Fcall_process_region): Ditto.

2334 rather than `XVECTOR (FOO)->size'.
2335
2336 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
2337 inttypes.h, as a gnulib replacement is used if it not available in
2338 system headers.
2339

2347 will grow beyond MOST_POSITIVE_FIXNUM.
2348 (decode_coding_emacs_mule): Abort if there isn't enough place in
2349 charbuf for the composition carryover bytes. Reserve an extra
2350 space for up to 2 characters produced in a loop.
2351 (decode_coding_iso_2022): Abort if there isn't enough place in

2361 * window.c (window_scroll_line_based): Use a marker instead of
2362 simple variables to record original value of point. (Bug#7952)
2363

2366
2367 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
2368

2394 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>

2399
2400 * makefile.w32-in: Update dependencies.

2402 2011-04-27 Eli Zaretskii <eliz@gnu.org>
2403
2404 Improve `doprnt' and its usage. (Bug#8545)
2405 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
2406 `format_end'. Remove support for %l as a conversion specifier.
2407 Don't use xrealloc. Improve diagnostics when the %l size modifier
2408 is used. Update the commentary.
2409
2410 * eval.c (verror): Simplify calculation of size_t.
2411
2412 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
2413 messages.
2414
2415 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
2416
2417 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
2418 change.
2419
2420 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
2421
2422 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
2423 This makes this file independent of the recent pseudovector change.
2424
2425 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
2426
2427 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
2428
2429 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
2430 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
2431 Remove unused local.
2432 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
2433
2434 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
2435 GCC 4.6.0 optimizes based on type-based alias analysis.
2436 For example, if b is of type struct buffer * and v of type struct
2437 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
2438 != &v->size, and therefore "v->size = 1; b->size = 2; return
2439 v->size;" must therefore return 1. This assumption is incorrect
2440 for Emacs, since it type-puns struct Lisp_Vector * with many other
2441 types. To fix this problem, this patch adds a new type struct
2442 vectorlike_header that documents the constraints on layout of vectors
2443 and pseudovectors, and helps optimizing compilers not get fooled
2444 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
2445 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
2446 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
2447 the size member.
2448 (XSETPVECTYPE): Rewrite in terms of new macro.
2449 (XSETPVECTYPESIZE): New macro, specifying both type and size.
2450 This is a bit clearer, and further avoids the possibility of
2451 undesirable aliasing.
2452 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
2453 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
2454 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
2455 since Lisp_Subr is a special case (no "next" field).
2456 (ASIZE): Now uses header.size rather than size.
2457 All previous uses of XVECTOR (foo)->size replaced to use this macro,
2458 to avoid the hassle of writing XVECTOR (foo)->header.size.
2459 (struct vectorlike_header): New type.
2460 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
2461 object, to help avoid aliasing.
2462 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
2463 (SUBRP): Likewise, since Lisp_Subr is a special case.
2464 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
2465 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
2466 (struct Lisp_Hash_Table): Combine first two members into a single
2467 struct vectorlike_header member. All uses of "size" and "next" members
2468 changed to be "header.size" and "header.next".
2469 * buffer.h (struct buffer): Likewise.
2470 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
2471 * frame.h (struct frame): Likewise.
2472 * process.h (struct Lisp_Process): Likewise.
2473 * termhooks.h (struct terminal): Likewise.
2474 * window.c (struct save_window_data, struct saved_window): Likewise.
2475 * window.h (struct window): Likewise.
2476 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
2477 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
2478 * buffer.c (init_buffer_once): Likewise.
2479 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
2480 special case.
2481 * process.c (Fformat_network_address): Use local var for size,
2482 for brevity.
2483
2484 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
2485
2486 Make the Lisp reader and string-to-float more consistent (Bug#8525)
2487 * data.c (atof): Remove decl; no longer used or needed.
2488 (digit_to_number): Move to lread.c.
2489 (Fstring_to_number): Use new string_to_number function, to be
2490 consistent with how the Lisp reader treats infinities and NaNs.
2491 Do not assume that floating-point numbers represent EMACS_INT
2492 without losing information; this is not true on most 64-bit hosts.
2493 Avoid double-rounding errors, by insisting on integers when
2494 parsing non-base-10 numbers, as the documentation specifies.
2495 * lisp.h (string_to_number): New decl, replacing ...
2496 (isfloat_string): Remove.
2497 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
2498 (read1): Do not accept +. and -. as integers; this
2499 appears to have been a coding error. Similarly, do not accept
2500 strings like +-1e0 as floating point numbers. Do not report
2501 overflow for integer overflows unless the base is not 10 which
2502 means we have no simple and reliable way to continue.
2503 Break out the floating-point parsing into a new
2504 function string_to_number, so that Fstring_to_number parses
2505 floating point numbers consistently with the Lisp reader.
2506 (digit_to_number): Move here from data.c. Make it static inline.
2507 (E_CHAR, EXP_INT): Remove, replacing with ...
2508 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
2509 (string_to_number): New function, replacing isfloat_string.
2510 This function checks for valid syntax and produces the resulting
2511 Lisp float number too. Rework it so that string-to-number
2512 no longer mishandles examples like "1.0e+". Use strtoumax,
2513 so that overflow for non-base-10 numbers is reported only when
2514 there's no portable and simple way to convert to floating point.
2515
2516 * textprop.c (set_text_properties_1): Rewrite for clarity,
2517 and to avoid GCC warning about integer overflow.
2518
2519 * intervals.h (struct interval): Use EMACS_INT for members
2520 where EMACS_UINT might cause problems. See
2521 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
2522 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
2523 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
2524 All uses changed.
2525 (offset_intervals): Tell GCC not to worry about length overflow
2526 when negating a negative length.
2527
2528 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
2529 (overrun_check_free): Likewise.
2530
2531 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
2532 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
2533 word size.
2534
2535 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2536 (gnutls_make_error): Rename local to avoid shadowing.
2537 (gnutls_emacs_global_deinit): ifdef out; not used.

2539 Comment out unused local. Fix pointer signedness problems.
2540
2541 * lread.c (openp): Don't stuff size_t into an 'int'.
2542 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
2543 about possible signed overflow.
2544
2545 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2546 (GDK_KEY_g): Don't define if already defined.

2548 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
2549
2550 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
2551 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
2552
2553 * xfns.c (Fx_window_property): Simplify a bit,
2554 to make a bit faster and to avoid GCC 4.6.0 warning.
2555 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
2556
2557 * fns.c (internal_equal): Don't assume size_t fits in int.
2558
2559 * alloc.c (compact_small_strings): Tighten assertion a little.
2560
2561 Replace pEd with more-general pI, and fix some printf arg casts.
2562 * lisp.h (pI): New macro, generalizing old pEd macro to other
2563 conversion specifiers. For example, use "...%"pI"d..." rather
2564 than "...%"pEd"...".
2565 (pEd): Remove. All uses replaced with similar uses of pI.
2566 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
2567 * alloc.c (check_pure_size): Don't overflow by converting size to int.
2568 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
2569 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.

2573 64-bit hosts.
2574 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
2575 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
2576 * print.c (safe_debug_print, print_object): Likewise.
2577 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
2578 to int.
2579 Use pI instead of if-then-else-abort. Use %p to avoid casts,
2580 avoiding the 0 flag, which is not portable.
2581 * process.c (Fmake_network_process): Use pI to avoid cast.
2582 * region-cache.c (pp_cache): Likewise.
2583 * xdisp.c (decode_mode_spec): Likewise.
2584 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
2585 behavior on 64-bit hosts with printf arg.

2587 (x_stop_queuing_selection_requests): Likewise.
2588 (x_get_window_property): Don't truncate byte count to an 'int'
2589 when tracing.
2590
2591 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
2592 here, since it parses constructs like leading '-' and spaces,
2593 which are not wanted; and it overflows with large numbers.
2594 Instead, simply match F[0-9]+, which is what is wanted anyway.
2595
2596 * alloc.c: Remove unportable assumptions about struct layout.
2597 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
2598 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
2599 (allocate_vectorlike, make_pure_vector): Use the new macros,
2600 plus offsetof, to remove unportable assumptions about struct layout.
2601 These assumptions hold on all porting targets that I know of, but
2602 they are not guaranteed, they're easy to remove, and removing them
2603 makes further changes easier.
2604
2605 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
2606 This doesn't fix a bug but makes the code clearer.
2607 (string_overrun_cookie): Now const. Use initializers that
2608 don't formally overflow signed char, to avoid warnings.
2609 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
2610 can cause Emacs to crash when string overrun checking is enabled.
2611 (allocate_buffer): Don't assume sizeof (struct buffer) is a
2612 multiple of sizeof (EMACS_INT); it need not be, if
2613 alignof(EMACS_INT) < sizeof (EMACS_INT).
2614 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
2615
2616 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

2635
2636 * alloc.c (check_sblock, check_string_bytes)

2644
2645 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
2646 "cast to pointer from integer of different size".
2647
2648 Improve doprnt and its use in verror. (Bug#8545)
2649 * doprnt.c (doprnt): Document the set of format control sequences
2650 supported by the function. Use SAFE_ALLOCA instead of always
2651 using `alloca'.
2652
2653 * eval.c (verror): Don't limit the buffer size at size_max-1, that
2654 is one byte too soon. Don't use xrealloc; instead xfree and
2655 xmalloc anew.
2656
2657 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
2658
2659 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
2660 callbacks stage.
2661
2662 * gnutls.c: Renamed global_initialized to
2663 gnutls_global_initialized. Added internals for the
2664 :verify-hostname-error, :verify-error, and :verify-flags
2665 parameters of `gnutls-boot' and documented those parameters in the
2666 docstring. Start callback support.
2667 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
2668 unless a fatal error occured. Call gnutls_alert_send_appropriate
2669 on error. Return error code.

2741 * doprnt.c: Include limits.h.
2742 (SIZE_MAX): New macro.
2743 (doprnt): Return a size_t value. 2nd arg is now size_t.
2744 Many local variables are now size_t instead of int or unsigned.
2745 Improve overflow protection. Support `l' modifier for integer
2746 conversions. Support %l conversion. Don't assume an EMACS_INT
2747 argument for integer conversions and for %c.
2748
2749 * lisp.h (doprnt): Restore prototype.
2750
2751 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

2764 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
2765
2766 * callint.c (Fcall_interactively): When displaying error message
2767 about invalid control letter, pass the character's codepoint, not

2769 in octal and display also its hex code.
2770
2771 * character.c (char_string): Use %x to display the (unsigned)
2772 codepoint of an invalid character, to avoid displaying a bogus

2973 * nsfont.m: Fixed bugs in ns_get_family and
2974 ns_descriptor_to_entity that were caused by using free to

2977 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
2978 --enable-checking=xmallocoverrun). xfree is now used to
2979 deallocate these memory blocks.

3352 (message_enable_multibyte, free_misc): Remove.
3353 (catchlist, handlerlist, mark_backtrace):
3354 Declare only if BYTE_MARK_STACK.
3355 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
3356 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
3357 (message_enable_multibyte): Remove decl.
3358 (free_misc, interval_free_list, float_block, float_block_index):
3359 (n_float_blocks, float_free_list, cons_block, cons_block_index):
3360 (cons_free_list, last_marked_index):
3361 Now static.
3362 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
3363 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
3364 (mark_backtrace): Define only if BYTE_MARK_STACK.
3365 * xdisp.c (message_enable_multibyte): Now static.
3366
3367 Declare Lisp_Object Q* variables to be 'static' if not exported.
3368 This makes it easier for human readers (and static analyzers)
3369 to see whether these variables are used from other modules.
3370 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
3371 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
3372 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
3373 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:

3375 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
3376 * xmenu.c, xselect.c:
3377 Declare Q* vars static if they are not used in other modules.
3378 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
3379 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
3380 Remove decls of unexported vars.
3381 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
3382
3383 * lisp.h (DEFINE_FUNC): Make sname 'static'.
3384
3385 Make Emacs functions such as Fatom 'static' by default.
3386 This makes it easier for human readers (and static analyzers)
3387 to see whether these functions can be called from other modules.
3388 DEFUN now defines a static function. To make the function external
3389 so that it can be used in other C modules, use the new macro DEFUE.
3390 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
3391 (Finit_image_library):
3392 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
3393 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
3394 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
3395 Remove decls, since these functions are now static.
3396 (Funintern, Fget_internal_run_time): New decls, since these functions
3397 were already external.
3398
3399 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
3400 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
3401 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:

3404 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
3405 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
3406 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
3407 Mark functions with DEFUE instead of DEFUN,
3408 if they are used in other modules.
3409 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
3410 decls for now-static functions.
3411 * buffer.h (Fdelete_overlay): Remove decl.
3412 * callproc.c (Fgetenv_internal): Mark as internal.
3413 * composite.c (Fremove_list_of_text_properties): Remove decl.
3414 (Fcomposition_get_gstring): New forward static decl.
3415 * composite.h (Fcomposite_get_gstring): Remove decl.

3420 * fileio.c (Fmake_symbolic_link): New forward static decl.
3421 * image.c (Finit_image_library): New forward static decl.
3422 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
3423 * intervals.h (Fprevious_property_change):
3424 (Fremove_list_of_text_properties): Remove decls.
3425 * keyboard.c (Fthis_command_keys): Remove decl.
3426 (Fcommand_execute): New forward static decl.
3427 * keymap.c (Flookup_key): New forward static decl.
3428 (Fcopy_keymap): Now static.
3429 * keymap.h (Flookup_key): Remove decl.
3430 * process.c (Fget_process): New forward static decl.
3431 (Fprocess_datagram_address): Mark as internal.
3432 * syntax.c (Fsyntax_table_p): New forward static decl.

3436 Now internal.
3437 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
3438 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
3439
3440 * editfns.c (Fformat): Remove unreachable code.
3441
3442 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
3443
3444 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
3445 change. (Bug#8496)
3446
3447 2011-04-13 Eli Zaretskii <eliz@gnu.org>
3448
3449 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
3450 when at ZV. (Bug#8487)
3451
3452 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
3453
3454 * charset.c (Fclear_charset_maps): Use xfree instead of free.
3455 (Bug#8437)
3456 * keyboard.c (parse_tool_bar_item): Likewise.
3457 * sound.c (sound_cleanup, alsa_close): Likewise.
3458 * termcap.c (tgetent): Likewise.
3459 * xfns.c (x_default_font_parameter): Likewise.
3460 * xsettings.c (read_and_apply_settings): Likewise.
3461
3462 * alloc.c (overrun_check_malloc, overrun_check_realloc)
3463 (overrun_check_free): Protoize.
3464
3465 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
3466
3467 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
3468 since callers should never pass a negative size.
3469 Change the signature to match that of plain 'read' and 'write'; see
3470 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
3471 * lisp.h: Update prototypes of emacs_write and emacs_read.
3472
3473 2011-04-11 Eli Zaretskii <eliz@gnu.org>
3474
3475 * xdisp.c (redisplay_window): Don't try to determine the character
3476 position of the scroll margin if the window start point w->startp
3477 is outside the buffer's accessible region. (Bug#8468)
3478
3479 2011-04-10 Eli Zaretskii <eliz@gnu.org>
3480
3481 Fix write-region and its subroutines for buffers > 2GB.
3482 * fileio.c (a_write, e_write): Modify declaration of arguments and
3483 local variables to support buffers larger than 2GB.
3484 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
3485
3486 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
3487 argument, local variables, and return value.
3488
3489 * lisp.h: Update prototypes of emacs_write and emacs_read.
3490
3491 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
3492
3493 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
3494
3495 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
3496
3497 Fix more problems found by GCC 4.6.0's static checks.
3498
3499 * xdisp.c (vmessage): Use a better test for character truncation.
3500
3501 * charset.c (load_charset_map): <, not <=, for optimization,
3502 and to avoid potential problems with integer overflow.
3503 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
3504 * casetab.c (set_identity, shuffle): Likewise.
3505 * editfns.c (Fformat): Likewise.
3506 * syntax.c (skip_chars): Likewise.
3507
3508 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
3509 This also lets GCC 4.6.0 generate slightly better loop code.
3510
3511 * callint.c (Fcall_interactively): <, not <=, for optimization.
3512 (Fcall_interactively): Count the number of arguments produced,
3513 not the number of arguments given. This is simpler and lets GCC
3514 4.6.0 generate slightly better code.
3515
3516 * ftfont.c: Distingish more carefully between FcChar8 and char.
3517 The previous code passed unsigned char * to a functions like
3518 strlen and xstrcasecmp that expect char *, which does not
3519 conform to the C standard.
3520 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
3521 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
3522 char * when the C standard requires it.
3523
3524 * keyboard.c (read_char): Remove unused var.
3525
3526 * eval.c: Port to Windows vsnprintf (Bug#8435).
3527 Include <limits.h>.
3528 (SIZE_MAX): Define if the headers do not.
3529 (verror): Do not give up if vsnprintf returns a negative count.
3530 Instead, grow the buffer. This ports to Windows vsnprintf, which
3531 does not conform to C99. Problem reported by Eli Zaretskii.
3532 Also, simplify the allocation scheme, by avoiding the need for
3533 calling realloc, and removing the ALLOCATED variable.
3534
3535 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
3536
3537 Remove invocations of doprnt, as Emacs now uses vsnprintf.
3538 But keep the doprint source code for now, as we might revamp it
3539 and use it again (Bug#8435).
3540 * lisp.h (doprnt): Remove.
3541 * Makefile.in (base_obj): Remove doprnt.o.
3542 * deps.mk (doprnt.o): Remove.
3543
3544 error: Print 32- and 64-bit integers portably (Bug#8435).
3545 Without this change, on typical 64-bit hosts error ("...%d...", N)
3546 was used to print both 32- and 64-bit integers N, which relied on
3547 undefined behavior.
3548 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
3549 New macro.
3550 * lisp.h (error, verror): Mark as printf-like functions.
3551 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
3552 Report overflow in size calculations when allocating printf buffer.
3553 Do not truncate output string at its first null byte.
3554 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
3555 Truncate the output at a character boundary, since vsnprintf does not
3556 do that.
3557 * charset.c (check_iso_charset_parameter): Convert internal
3558 character to string before calling 'error', since %c now has the
3559 printf meaning.
3560 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
3561 overflow when computing char to be passed to 'error'. Do not
3562 pass Lisp_Object to 'error'; pass the integer instead.
3563 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
3564 formatted with plain %d.
3565
3566 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
3567
3568 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
3569
3570 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
3571
3572 * xterm.c (x_catch_errors): Remove duplicate declaration.
3573
3574 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
3575
3576 * xdisp.c, lisp.h (message_nolog): Remove; unused.
3577
3578 2011-04-10 Jim Meyering <meyering@redhat.com>
3579
3580 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
3581 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
3582 return ssize_t not "int", and use size_t as the buffer length.
3583 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
3584 * gnutls.h: Update declarations.
3585 * process.c (read_process_output): Use ssize_t, to match.
3586 (send_process): Likewise.
3587
3588 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3589
3590 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
3591
3592 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3593
3594 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
3595 Use unsigned char, to match FcChar8 type definition.
3596
3597 * xterm.c (handle_one_xevent):
3598 * xmenu.c (create_and_show_popup_menu):
3599 * xselect.c (x_decline_selection_request)
3600 (x_reply_selection_request): Avoid type-punned deref of X events.
3601
3602 2011-04-09 Eli Zaretskii <eliz@gnu.org>
3603
3604 Fix some uses of `int' instead of EMACS_INT.
3605 * search.c (string_match_1, fast_string_match)
3606 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
3607 (scan_buffer, find_next_newline_no_quit)
3608 (find_before_next_newline, search_command, Freplace_match)
3609 (Fmatch_data): Make some `int' variables be EMACS_INT.
3610
3611 * xdisp.c (display_count_lines): 3rd argument and return value now
3612 EMACS_INT. All callers changed.
3613 (pint2hrstr): Last argument is now EMACS_INT.
3614
3615 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
3616 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
3617 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
3618 (decode_coding_utf_16, decode_coding_emacs_mule)
3619 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
3620 (decode_coding_ccl, decode_coding_charset)
3621 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
3622 (decode_coding_iso_2022, decode_coding_emacs_mule)
3623 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
3624 <char_offset, last_offset>: Declare EMACS_INT.
3625 (encode_coding_utf_8, encode_coding_utf_16)
3626 (encode_coding_emacs_mule, encode_invocation_designation)
3627 (encode_designation_at_bol, encode_coding_iso_2022)
3628 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
3629 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
3630 Declare EMACS_INT.
3631 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
3632 (encode_invocation_designation): Last argument P_NCHARS is now
3633 EMACS_INT.
3634 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
3635 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
3636
3637 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
3638 All users changed.
3639
3640 * ccl.c (Fccl_execute_on_string): Declare some variables
3641 EMACS_INT.
3642
3643 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
3644
3645 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).

3649 * process.c (Fformat_network_address): Doc fix.
3650
3651 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
3652
3653 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
3654
3655 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
3656
3657 * keyboard.c (read_char): Call Lisp function help-form-show,
3658 instead of using internal_with_output_to_temp_buffer.
3659 (Qhelp_form_show): New var.
3660 (syms_of_keyboard): Use DEFSYM macro.
3661
3662 * print.c (internal_with_output_to_temp_buffer): Function deleted.
3663
3664 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
3665
3666 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
3667
3668 * process.c (Flist_processes): Remove to Lisp.
3669 (list_processes_1): Delete.
3670
3671 2011-04-06 Eli Zaretskii <eliz@gnu.org>
3672
3673 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
3674
3675 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
3676
3677 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
3678
3679 Fix more problems found by GCC 4.6.0's static checks.
3680
3681 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
3682
3683 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
3684
3685 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
3686
3687 * xdisp.c (vmessage): Mark as a printf-like function.

3694 printf-like functions.
3695 (tiff_load): Add casts to remove these marks before passing them
3696 to system-supplied API.
3697
3698 * eval.c (Fsignal): Remove excess argument to 'fatal'.
3699
3700 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
3701 This avoids several warnings with gcc -Wstrict-overflow.
3702 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
3703 directly, rather than having caller test rule sign. This avoids
3704 some unnecessary tests.
3705 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
3706 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
3707 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
3708
3709 * xfont.c (xfont_text_extents): Remove var that was set but not used.
3710 (xfont_open): Avoid unnecessary tests.
3711
3712 * composite.c (composition_gstring_put_cache): Use unsigned integer.
3713
3714 * composite.h, composite.c (composition_gstring_put_cache):
3715 Use EMACS_INT, not int, for length.
3716
3717 * composite.h (COMPOSITION_DECODE_REFS): New macro,
3718 breaking out part of COMPOSITION_DECODE_RULE.
3719 (COMPOSITION_DECODE_RULE): Use it.
3720 * composite.c (get_composition_id): Remove unused local vars,
3721 by using the new macro.
3722
3723 * textprop.c (set_text_properties_1): Change while to do-while,
3724 since the condition is always true at first.
3725
3726 * intervals.c (graft_intervals_into_buffer): Mark var as used.
3727 (interval_deletion_adjustment): Return unsigned value.
3728 All uses changed.
3729
3730 * process.c (list_processes_1, create_pty, read_process_output):
3731 (exec_sentinel): Remove vars that were set but not used.
3732 (create_pty): Remove unnecessary "volatile"s.
3733 (Fnetwork_interface_info): Avoid possibility of int overflow.
3734 (read_process_output): Do adaptive read buffering even if carryover.
3735 (read_process_output): Simplify nbytes computation if buffered.
3736
3737 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
3738
3739 * syntax.c (scan_words): Remove var that was set but not used.
3740 (update_syntax_table): Use unsigned instead of int.
3741
3742 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
3743 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
3744 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
3745
3746 * print.c (print_error_message): Avoid int overflow.
3747
3748 * font.c (font_list_entities): Redo for clarity,
3749 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
3750
3751 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
3752 (font_score): Avoid potential overflow in diff calculation.
3753
3754 * fns.c (substring_both): Remove var that is set but not used.
3755 (sxhash): Redo loop for clarity and to avoid wraparound warning.
3756
3757 * eval.c (funcall_lambda): Rename local to avoid shadowing.
3758
3759 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
3760 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
3761 can always succeed if overflow has undefined behavior.
3762
3763 * search.c (boyer_moore, wordify): Remove vars set but not used.
3764 (wordify): Omit three unnecessary tests.
3765
3766 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

3788
3789 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
3790
3791 * image.c (lookup_image): Remove var that is set but not used.
3792 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
3793
3794 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
3795 that are set but not used.
3796
3797 * xfns.c (make_invisible_cursor): Don't return garbage
3798 if XCreateBitmapFromData fails (Bug#8410).
3799
3800 * xselect.c (x_get_local_selection, x_handle_property_notify):
3801 Remove vars that are set but not used.
3802
3803 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
3804 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
3805
3806 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
3807 Remove var that is set but not used.
3808 (scroll_bar_windows_size): Now size_t, not int.
3809 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
3810 Check for overflow.
3811
3812 * xfaces.c (realize_named_face): Remove vars that are set but not used.
3813 (map_tty_color) [!defined MSDOS]: Likewise.
3814
3815 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
3816
3817 * coding.c: Remove vars that are set but not used.
3818 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
3819 All callers changed.
3820 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
3821 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
3822 (decode_coding_charset): Remove vars that are set but not used.
3823
3824 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
3825 that is set but not used.
3826
3827 * print.c (print_object): Remove var that is set but not used.
3828
3829 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
3830 The gnulib version avoids calling malloc in the usual case,
3831 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
3832 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
3833 * filelock.c (current_lock_owner): Likewise.
3834 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
3835 * sysdep.c: Include allocator.h, careadlinkat.h.
3836 (emacs_no_realloc_allocator): New static constant.
3837 (emacs_readlink): New function.
3838 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
3839 ../lib/careadlinkat.h.
3840
3841 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
3842
3843 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
3844 first non-nil return value).
3845
3846 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
3847
3848 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
3849 if not defined (Bug#8403).
3850
3851 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
3852
3853 * xdisp.c (display_count_lines): Remove parameter `start',
3854 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3855 (get_char_face_and_encoding): Remove parameter `multibyte_p',
3856 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

3865 do not dereference NULL upon failed strdup
3866 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
3867 (ns_get_family): Likewise.
3868
3869 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
3870
3871 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
3872
3873 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
3874
3875 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
3876 later (Bug#8403).
3877
3878 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
3879
3880 Add lexical binding.
3881
3882 * window.c (Ftemp_output_buffer_show): New fun.
3883 (Fsave_window_excursion):
3884 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
3885
3886 * lread.c (lisp_file_lexically_bound_p): New function.
3887 (Fload): Bind Qlexical_binding.
3888 (readevalloop): Remove `evalfun' arg.
3889 Bind Qinternal_interpreter_environment.
3890 (Feval_buffer): Bind Qlexical_binding.
3891 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
3892 Mark as dynamic.
3893 (syms_of_lread): Declare `lexical-binding'.
3894
3895 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
3896
3897 * keyboard.c (eval_dyn): New fun.
3898 (menu_item_eval_property): Use it.
3899
3900 * image.c (parse_image_spec): Use Ffunctionp.
3901
3902 * fns.c (concat, mapcar1): Accept byte-code-functions.
3903
3904 * eval.c (Fsetq): Handle lexical vars.
3905 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
3906 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
3907 (FletX, Flet): Obey lexical binding.
3908 (Fcommandp): Handle closures.
3909 (Feval): New `lexical' arg.
3910 (eval_sub): New function extracted from Feval. Use it almost
3911 everywhere where Feval was used. Look up vars in lexical env.
3912 Handle closures.
3913 (Ffunctionp): Move from subr.el.
3914 (Ffuncall): Handle closures.
3915 (apply_lambda): Remove `eval_flags'.
3916 (funcall_lambda): Handle closures and new byte-code-functions.
3917 (Fspecial_variable_p): New function.
3918 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
3919 but without exporting it to Lisp.
3920
3921 * doc.c (Fdocumentation, store_function_docstring):
3922 * data.c (Finteractive_form): Handle closures.
3923
3924 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
3925 interactive spec.
3926
3927 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
3928 New byte-codes.
3929 (exec_byte_code): New function extracted from Fbyte_code to handle new
3930 calling convention for byte-code-functions. Add new byte-codes.
3931
3932 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
3933
3934 * alloc.c (Fmake_symbol): Init new `declared_special' field.
3935
3936 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
3937
3938 * xdisp.c (redisplay_internal): Fix prototype.
3939
3940 2011-03-31 Eli Zaretskii <eliz@gnu.org>
3941
3942 * xdisp.c (SCROLL_LIMIT): New macro.
3943 (try_scrolling): Use it when setting scroll_limit.
3944 Limit scrolling to 100 screen lines.
3945 (redisplay_window): Even when falling back on "recentering",
3946 position point in the window according to scroll-conservatively,
3947 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
3948
3949 (try_scrolling): When point is above the window, allow searching
3950 as far as scroll_max, or one screenful, to compute vertical
3951 distance from PT to the scroll margin position. This prevents
3952 try_scrolling from unnecessarily failing when
3953 scroll-conservatively is set to a value slightly larger than the
3954 window height. Clean up the case of PT below the margin at bottom
3955 of window: scroll_max can no longer be INT_MAX. When aggressive
3956 scrolling is in use, don't let point enter the opposite scroll
3957 margin as result of the scroll.
3958 (syms_of_xdisp) <scroll-conservatively>: Document the
3959 threshold of 100 lines for never-recentering scrolling.
3960
3961 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

3965 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
3966 (message_log_check_duplicate): Remove parameters `prev_bol' and
3967 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3968 (redisplay_internal): Remove parameter `preserve_echo_area',
3969 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
3970
3971 * indent.c (Fvertical_motion):
3972 * window.c (window_scroll_pixel_based, Frecenter):
3973 Don't pass `need_y_p' to `move_it_by_lines'.
3974
3975 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
3976
3977 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
3978 steal a few bits to be more compact.

3980 Remove unneeded casts.
3981
3982 * bytecode.c (Fbyte_code): CAR and CDR can GC.
3983
3984 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
3985
3986 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
3987 binding" message (bug#7967).
3988
3989 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
3990
3991 Fix more problems found by GCC 4.6.0's static checks.
3992
3993 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
3994 Remove unused local var.
3995
3996 * editfns.c (Fmessage_box): Remove unused local var.
3997
3998 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
3999 (note_mode_line_or_margin_highlight, note_mouse_highlight):
4000 Omit unused local vars.
4001 * window.c (shrink_windows): Omit unused local var.
4002 * menu.c (digest_single_submenu): Omit unused local var.
4003 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
4004 Omit unused local var.
4005
4006 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
4007 Don't assume string length fits in int.
4008 (keyremap_step, read_key_sequence): Use size_t for sizes.
4009 (read_key_sequence): Don't check last_real_key_start redundantly.
4010
4011 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
4012 instead of alloca (Bug#8344).
4013
4014 * eval.c (Fbacktrace): Don't assume nargs fits in int.
4015 (Fbacktrace_frame): Don't assume nframes fits in int.
4016
4017 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
4018
4019 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
4020 concerns.
4021
4022 * term.c (produce_glyphless_glyph): Remove unnecessary test.
4023
4024 * cm.c (calccost): Turn while-do into do-while, for clarity.
4025
4026 * keyboard.c (syms_of_keyboard): Use the same style as later
4027 in this function when indexing through an array. This also
4028 works around GCC bug 48267.
4029
4030 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
4031
4032 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
4033

4035 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
4036
4037 * keyboard.c, keyboard.h (num_input_events): Now size_t.
4038 This avoids undefined behavior on integer overflow, and is a bit
4039 more convenient anyway since it is compared to a size_t variable.
4040
4041 Variadic C functions now count arguments with size_t, not int.
4042 This avoids an unnecessary limitation on 64-bit machines, which
4043 caused (substring ...) to crash on large vectors (Bug#8344).
4044 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
4045 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

4052 (funcall_lambda, mark_backtrace): Likewise.
4053 * fns.c (concat): Likewise.
4054 * frame.c (x_set_frame_parameters): Likewise.
4055 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
4056 0 if not found, not -1. All callers changed.
4057
4058 * alloc.c (garbage_collect): Don't assume stack size fits in int.
4059 (stack_copy_size): Now size_t, not int.
4060 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

4085 Vcommand_hook_internal.

4098
4099 * print.c (strout): Remove parameter `multibyte', unused since

4150 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
4151
4152 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
4153
4154 * w32.c (read_unc_volume): Use parameter `henum', instead of
4155 global variable `wget_enum_handle'.
4156
4157 * keymap.c (describe_vector): Remove parameters `indices' and
4158 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
4159 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
4160

4254
4255 * term.c (Fsuspend_tty, Fresume_tty):
4256 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
4257 * window.c (temp_output_buffer_show):
4258 * insdel.c (signal_before_change):

4271 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
4272
4273 Fix more problems found by GCC 4.5.2's static checks.
4274
4275 * coding.c (encode_coding_raw_text): Avoid unnecessary test
4276 the first time through the loop, since we know p0 < p1 then.
4277 This also avoids a gcc -Wstrict-overflow warning.
4278
4279 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
4280 leading to a memory leak, possible in functions like
4281 load_charset_map_from_file that can allocate an unbounded number
4282 of objects (Bug#8318).
4283
4284 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
4285 that could (at least in theory) be that large.
4286
4287 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
4288 This is less likely to overflow, and avoids undefined behavior if
4289 overflow does occur. All callers changed. Use strtoul to scan
4290 for the unsigned long integer.
4291 (pint2hrstr): Simplify and tune code slightly.
4292 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
4293

4295 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
4296
4297 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
4298 This also avoids a warning with gcc -Wstrict-overflow.

4300 This also avoids a warning with gcc -Wstrict-overflow.
4301
4302 * fileio.c (Fcopy_file): Report error if fchown or fchmod
4303 fail (Bug#8306).
4304
4305 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
4306
4307 * process.c (Fmake_network_process): Use socklen_t, not int,
4308 where POSIX says socklen_t is required in portable programs.
4309 This fixes a porting bug on hosts like 64-bit HP-UX, where
4310 socklen_t is wider than int (Bug#8277).
4311 (Fmake_network_process, server_accept_connection):
4312 (wait_reading_process_output, read_process_output):
4313 Likewise.
4314
4315 * process.c: Rename or move locals to avoid shadowing.

4322 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
4323 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
4324
4325 Make tparam.h and terminfo.c consistent.
4326 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
4327 Include tparam.h instead, since it declares them.
4328 * cm.h (PC): Remove extern decl; tparam.h now does this.
4329 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
4330 * terminfo.c: Include tparam.h, to check interfaces.
4331 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
4332 (tparam): Adjust signature to match interface in tparam.h;
4333 this removes some undefined behavior. Check that outstring and len
4334 are zero, which they always are with Emacs.
4335 * tparam.h (PC, BC, UP): New extern decls.
4336
4337 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

4353 avoid shadowing.
4354 (composition_reseat_it): Remove unused locals.
4355 (find_automatic_composition, composition_adjust_point): Likewise.
4356 (composition_update_it): Mark var as initialized.
4357 (find_automatic_composition): Mark vars as initialized,
4358 with a FIXME (Bug#8290).
4359
4360 character.h: Rename locals to avoid shadowing.
4361 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
4362 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
4363 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
4364 (BUF_DEC_POS): Be more systematic about renaming local temporaries
4365 to avoid shadowing.

4374 Rename locals to avoid shadowing.
4375
4376 * sound.c (wav_play, au_play, Fplay_sound_internal):
4377 Fix pointer signedness.
4378 (alsa_choose_format): Remove unused local var.
4379 (wav_play): Initialize a variable to 0, to prevent undefined
4380 behavior (Bug#8278).
4381
4382 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
4383
4384 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
4385
4386 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
4387 clobbering (Bug#8298).
4388 * sysdep.c (sys_subshell): Likewise.
4389 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
4390
4391 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
4392 This should get cleaned up, so that child_setup has the
4393 same signature on all platforms.
4394
4395 * callproc.c (call_process_cleanup): Now static.
4396 (relocate_fd): Rename locals to avoid shadowing.
4397
4398 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
4399
4400 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
4401 not to be necessary, and produces flickering.
4402
4403 2011-03-20 Glenn Morris <rgm@gnu.org>
4404
4405 * config.in: Remove file.
4406

4420
4421 * xfaces.c (Fx_load_color_file):
4422 Read color file from absolute filename (bug#8250).
4423
4424 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
4425
4426 * makefile.w32-in: Update dependencies.
4427

4437 (sigchld_handler): Now static.
4438
4439 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
4440 That way, the code declares only the vars that it needs.

4442 * s/cygwin.h (PTY_ITERATION): Likewise.
4443 * s/darwin.h (PTY_ITERATION): Likewise.

4458 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
4459
4460 * deps.mk (unexalpha.o): Remove; unused.

4522 Move decls here, to check interfaces.
4523 * process.c (get_operating_system_release): Move decl to lisp.h.

4566 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
4567 to use the following functions instead of these macros.
4568 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
4569 EMACS_INT, since callers assume the returned value fits in int.
4570 (upcase1): Likewise, for UPCASE_TABLE.

4572 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

4584 (WORDCHAR_P): Likewise. This one is never needed, but is used
4585 only in a comment talking about a compiler bug, so put inside
4586 the #if 0 of that comment.
4587 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
4588 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
4589 Remove; unused.
4590
4591 * search.c (boyer_moore): Rename locals to avoid shadowing.
4592 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
4593 (PREV_CHAR_BOUNDARY): Likewise.
4594
4595 * search.c (simple_search): Remove unused var.
4596
4597 * dired.c (compile_pattern): Move decl from here ...
4598 * lisp.h: ... to here, so that it can be checked.
4599 (struct re_registers): New forward decl.
4600
4601 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
4602
4603 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
4604 All uses changed.
4605 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
4606 Rename locals to avoid shadowing.
4607 (Fvertical_motion): Mark locals as initialized.
4608
4609 * casefiddle.c (casify_object, casify_region): Now static.

4614 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
4615 New macros, so that the caller can use some names other than
4616 gcpro1, gcpro2, etc.
4617 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
4618 of the new macros.
4619 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
4620 argument, for consistency with GCPRO2_VAR, etc: it is now the

4624 Rename locals to avoid shadowing.
4625
4626 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
4627 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
4628 dired.c's scmp function, had undefined behavior.
4629 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4630 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
4631 * buffer.h: ... to here, because these macros use current_buffer,
4632 and the new implementation with inline functions needs to have
4633 current_buffer in scope now, rather than later when the macros
4634 are used.
4635 (downcase, upcase1): New static inline functions.
4636 (DOWNCASE, UPCASE1): Reimplement using these functions.
4637 This avoids undefined behavior in expressions like
4638 DOWNCASE (x) == DOWNCASE (y), which previously suffered
4639 from race conditions in accessing the global variables
4640 case_temp1 and case_temp2.
4641 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
4642 * lisp.h (case_temp1, case_temp2): Remove their decls.
4643 * character.h (ASCII_CHAR_P): Move from here ...
4644 * lisp.h: ... to here, so that the inline functions mentioned
4645 above can use them.
4646
4647 * dired.c (directory_files_internal_unwind): Now static.
4648
4649 * fileio.c (file_name_as_directory, directory_file_name):

4651 Now static.
4652 (file_name_as_directory): Use const pointers when appropriate.
4653 (Fexpand_file_name): Likewise. In particular, newdir might
4654 point at constant storage, so make it a const pointer.

4656 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
4657 signedness issues.

4662 (Ftry_completion, Fall_completions): Rename or remove locals
4663 to avoid shadowing.
4664
4665 * marker.c (bytepos_to_charpos): Remove; unused.
4666
4667 * lisp.h (verify_bytepos, count_markers): New decls,
4668 so that gcc does not warn that these functions aren't declared.
4669
4670 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
4671 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
4672 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
4673 (copy_text): Remove unused local var.
4674
4675 * filelock.c (within_one_second): Now static.
4676 (lock_file_1): Rename local to avoid shadowing.
4677
4678 * buffer.c (fix_overlays_before): Mark locals as initialized.
4679 (fix_start_end_in_overlays): Likewise. This function should be
4680 simplified by using pointers-to-pointers, but that's a different
4681 matter.
4682 (switch_to_buffer_1): Now static.
4683 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
4684 (report_overlay_modification): Rename locals to avoid shadowing.
4685
4686 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
4687 Fix pointer signedness issue.
4688 (sys_subshell): Mark local as volatile if checking for lint,
4689 to suppress a gcc -Wclobbered warning that does not seem to be right.
4690 (MAXPATHLEN): Define only if needed.
4691
4692 * process.c (serial_open, serial_configure): Move decls from here ...

4700
4701 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
4702 (copy_keymap_item, append_key, push_text_char_description):
4703 Now static.
4704 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
4705 (DENSE_TABLE_SIZE): Remove; unused.
4706 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
4707 (describe_map_tree):
4708 Rename locals to avoid shadowing.
4709
4710 * keyboard.c: Declare functions static if they are not used elsewhere.
4711 (echo_char, echo_dash, cmd_error, top_level_2):

4726
4727 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
4728 (DEFINE_DUMMY_FUNCTION): New macro.
4729 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
4730 Use it.
4731 (main): Add casts to avoid warnings
4732 if GCC considers string literals to be constants.
4733
4734 * lisp.h (fatal_error_signal): Add decl, since it's exported.
4735
4736 * dbusbind.c: Pointer signedness fixes.
