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

261 * print.c (printchar, strout): Check for string overflow.
262 (PRINTPREPARE, printchar, strout):
263 Don't set size unless allocation succeeds.
265 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
266 for sizes. Check for string overflow more accurately.

274 Check for size-calculation overflow.
275 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
277 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
279 * lread.c: Integer overflow fixes.
280 (read_integer): Radix is now EMACS_INT, not int,
281 to improve quality of diagnostics for out-of-range radices.
282 Calculate buffer size correctly for out-of-range radices.
283 (read1): Check for integer overflow in radices, and in
285 (read_escape): Avoid int overflow.
286 (Fload, openp, read_buffer_size, read1)
287 (substitute_object_recurse, read_vector, read_list, map_obarray):

301 (read_escape): Check for hex character overflow.
303 2011-06-22 Leo Liu <sdl.web@gmail.com>
305 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
306 Move to minibuffer.el.
308 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
310 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
311 The following patches are for when GLYPH_DEBUG && !XASSERT.
312 * dispextern.h (trace_redisplay_p, dump_glyph_string):
313 * dispnew.c (flush_stdout):
314 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
315 Mark as externally visible.
316 * dispnew.c (check_window_matrix_pointers): Now static.
317 * dispnew.c (window_to_frame_vpos):
318 * xfns.c (unwind_create_frame):

320 * scroll.c (CHECK_BOUNDS):
321 * xfaces.c (cache_fache): Rename local to avoid shadowing.
322 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
323 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
324 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
325 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
327 (debug_method_add): Use va_list and vsprintf rather than relying
328 on undefined behavior with wrong number of arguments.
329 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
330 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
331 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
332 since we're not interested in debugging glyphs with old libraries.
333 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
334 GCC 4.6.0's static checking.
336 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
338 Integer overflow and signedness fixes (Bug#8873).
339 A few related buffer overrun fixes, too.

345 (x_bitmap_mask, x_allocate_bitmap_record)
346 (x_create_bitmap_from_data, x_create_bitmap_from_file)
347 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
348 (x_create_bitmap_from_xpm_data):
349 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
350 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
352 * xfaces.c (load_pixmap):
353 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
354 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
355 (.bitmaps_last, struct x_output.icon_bitmap):
356 Use ptrdiff_t, not int, for bitmap indexes.
357 (x_allocate_bitmap_record): Check for size overflow.
358 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
360 Use ptrdiff_t, not int, for overlay counts.
361 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
362 * editfns.c (overlays_around, get_pos_property):
363 * textprop.c (get_char_property_and_overlay):
364 * xdisp.c (next_overlay_change, note_mouse_highlight):
365 * xfaces.c (face_at_buffer_position):
366 * buffer.c (OVERLAY_COUNT_MAX): New macro.
367 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
368 (Fnext_overlay_change, Fprevious_overlay_change)
369 (mouse_face_overlay_overlaps, Foverlays_in):
370 Use ptrdiff_t, not int, for sizes.

373 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
375 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
376 (x_session_initialize): Do not assume string length fits in int.
378 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
379 This is unlikely, but can occur if DPI is outlandish.
381 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
382 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
384 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
385 * xrdb.c (magic_file_p, search_magic_path):
386 Omit last arg SUFFIX; it was always 0. All callers changed.
387 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
389 * xfont.c (xfont_match): Avoid need for strlen.
391 * xfns.c: Don't assume strlen fits in int.
392 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
394 * xdisp.c (message_log_check_duplicate): Return intmax_t,
395 not unsigned long, as we prefer signed integers. All callers changed.
396 Detect integer overflow in repeat count.
397 (message_dolog): Don't assume print length fits in 39 bytes.
398 (display_mode_element): Don't assume strlen fits in int.
400 * termcap.c: Don't assume sizes fit in int and never overflow.
401 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
402 (gobble_line): Check for size-calculation overflow.
404 * minibuf.c (Fread_buffer):
405 * lread.c (intern, intern_c_string):
406 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
407 Don't assume string length fits in int.
409 * keyboard.c (parse_tool_bar_item):
410 * gtkutil.c (style_changed_cb): Avoid need for strlen.
412 * font.c: Don't assume string length fits in int.
413 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
414 Use ptrdiff_t, not int.

416 Don't assume integer property fits in fixnum.
417 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
419 * filelock.c: Fix some buffer overrun and integer overflow issues.
420 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
421 Reformulate so as not to need the command string.
422 Invoke gzip -cd rather than gunzip, as it's more portable.
423 (lock_info_type, lock_file_1, lock_file):
424 Don't assume pid_t and time_t fit in unsigned long.
425 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
426 (current_lock_owner): Prefer signed type for sizes.
427 Use memcpy, not strncpy, where memcpy is what is really wanted.
428 Don't assume (via atoi) that time_t and pid_t fit in int.
429 Check for time_t and/or pid_t out of range, e.g., via a network share.
430 Don't alloca where an auto var works fine.
432 * fileio.c: Fix some integer overflow issues.
433 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
434 Don't assume string length fits in int.
435 (directory_file_name): Don't assume string length fits in long.
436 (make_temp_name): Don't assume pid fits in int, or that its print
437 length is less than 20.
439 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
441 * coding.c (make_subsidiaries): Don't assume string length fits in int.
443 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
445 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
446 We prefer signed integers, even for size calculations.
448 * emacs.c: Don't assume string length fits in 'int'.
449 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
450 (main): Don't invoke strlen when not needed.
452 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

455 * callproc.c (getenv_internal_1, getenv_internal)
457 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
459 * lread.c (invalid_syntax): Omit length argument.
460 All uses changed. This doesn't fix a bug, but it simplifies the
461 code away from its former Hollerith-constant appearance, and it's
462 one less 'int' to worry about when looking at integer-overflow issues.
463 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
465 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
466 This didn't break anything, but it didn't help either.
467 It's confusing to put a bogus integer in a place where the actual
468 value does not matter.
469 (LIST_END_P): Remove unused macro and its bogus comment.
470 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
472 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
473 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
475 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
476 We prefer signed types, and the value cannot exceed the EMACS_INT
477 range anyway (because otherwise the length would not be representable).
478 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
479 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
480 This avoids a GCC warning when WIDE_EMACS_INT.
482 * indent.c (sane_tab_width): New function.
483 (current_column, scan_for_column, Findent_to, position_indentation)
484 (compute_motion): Use it. This is just for clarity.
485 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
487 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
489 * lisp.h (lint_assume): New macro.
490 * composite.c (composition_gstring_put_cache):
491 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
493 * editfns.c, insdel.c:
494 Omit unnecessary forward decls, to simplify future changes.
496 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
498 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
500 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
501 Use much-faster test for byte-length change.
502 Don't assume string byte-length fits in 'int'.
503 Check that character arg fits in 'int'.
504 (mapcar1): Declare byte as byte, for clarity.
506 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
508 * fns.c (concat): Catch string overflow earlier.
509 Do not rely on integer wraparound.
511 * dispextern.h (struct it.overlay_strings_charpos)
512 (struct it.selective): Now EMACS_INT, not int.
513 * xdisp.c (forward_to_next_line_start)
514 (back_to_previous_visible_line_start)
515 (reseat_at_next_visible_line_start, next_element_from_buffer):
516 Don't arbitrarily truncate the value of 'selective' to int.
518 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
520 * composite.c: Don't truncate sizes to 'int'.
521 (composition_gstring_p, composition_reseat_it)
522 (composition_adjust_point): Use EMACS_INT, not int.
523 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
524 not EMACS_UINT, for indexes.
526 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
528 * buffer.c: Include <verify.h>.
529 (struct sortvec.priority, struct sortstr.priority):
530 Now EMACS_INT, not int.
531 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
532 (struct sortstr.size, record_overlay_string)
533 (struct sortstrlist.size, struct sortlist.used):
534 Don't truncate size to int.
535 (record_overlay_string): Check for size-calculation overflow.
536 (init_buffer_once): Check at compile-time, not run-time.
538 2011-06-22 Jim Meyering <meyering@redhat.com>
540 Don't leak an XBM-image-sized buffer
541 * image.c (xbm_load): Free the image buffer after using it.
543 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
546 * composite.c (find_automatic_composition): Omit needless 'return 0;'
547 that Sun C diagnosed.
548 * fns.c (secure_hash): Fix pointer signedness issue.
549 * intervals.c (static_offset_intervals): New function.
550 (offset_intervals): Use it.
552 2011-06-21 Leo Liu <sdl.web@gmail.com>
555 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
558 * fns.c (secure_hash): Rename from crypto_hash_function and change
559 the first arg to accept symbols.
560 (Fsecure_hash): New primitive.
561 (syms_of_fns): New symbols.
563 2011-06-20 Deniz Dogan <deniz@dogan.se>
565 * process.c (Fset_process_buffer): Clarify return value in
568 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
570 * dispnew.c (add_window_display_history): Use BVAR.
572 * xdisp.c (debug_method_add): Use BVAR.
573 (check_window_end, dump_glyph_matrix, dump_glyph)
574 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
576 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
579 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
580 check till after the cache is created in init_frame_faces.
582 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
584 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
586 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
588 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
589 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
590 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
592 Improve buffer-overflow checking (Bug#8873).
593 * fileio.c (Finsert_file_contents):
594 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
595 Remove the old (too-loose) buffer overflow checks.
596 They weren't needed, since make_gap checks for buffer overflow.
597 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
598 The old code merely checked for Emacs fixnum overflow, and relied
599 on undefined (wraparound) behavior. The new code avoids undefined
600 behavior, and also checks for ptrdiff_t and/or size_t overflow.
602 * editfns.c (Finsert_char): Don't dump core with very negative counts.
603 Tune. Don't use wider integers than needed. Don't use alloca.
604 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
606 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
608 * insdel.c, lisp.h (buffer_overflow): New function.
609 (insert_from_buffer_1, replace_range, replace_range_2):
610 * insdel.c (make_gap_larger):
611 * editfns.c (Finsert_char):
612 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
614 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
616 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
618 Integer overflow and signedness fixes (Bug#8873).
620 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
621 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
623 * fileio.c: Don't assume EMACS_INT fits in off_t.
624 (emacs_lseek): New static function.
625 (Finsert_file_contents, Fwrite_region): Use it.
626 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
628 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
630 * fns.c: Don't overflow int when computing a list length.
631 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
632 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
633 truncation on 64-bit hosts. Check for QUIT every
634 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
635 faster and is responsive enough.
636 (Flength): Report an error instead of overflowing an integer.
637 (Fsafe_length): Return a float if the value is not representable
638 as a fixnum. This shouldn't happen except in contrived situations.
639 (Fnthcdr, Fsort): Don't assume list length fits in int.
640 (Fcopy_sequence): Don't assume vector length fits in int.
642 * alloc.c: Check that resized vectors' lengths fit in fixnums.
643 (header_size, word_size): New constants.
644 (allocate_vectorlike): Don't check size overflow here.
645 (allocate_vector): Check it here instead, since this is the only
646 caller of allocate_vectorlike that could cause overflow.
647 Check that the new vector's length is representable as a fixnum.
649 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
650 The previous code was bogus. For example, next_almost_prime (32)
651 returned 39, which is undesirable as it is a multiple of 3; and
652 next_almost_prime (24) returned 25, which is a multiple of 5 so
653 why was the code bothering to check for multiples of 7?
655 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
657 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
659 Variadic C functions now count arguments with ptrdiff_t.
660 This partly undoes my 2011-03-30 change, which replaced int with size_t.
661 Back then I didn't know that the Emacs coding style prefers signed int.
662 Also, in the meantime I found a few more instances where arguments
663 were being counted with int, which may truncate counts on 64-bit
664 machines, or EMACS_INT, which may be unnecessarily wide.
665 * lisp.h (struct Lisp_Subr.function.aMANY)
666 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
667 Arg counts are now ptrdiff_t, not size_t.
668 All variadic functions and their callers changed accordingly.
669 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
670 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
671 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
672 * callint.c (Fcall_interactively): Check arg count for overflow,
673 to avoid potential buffer overrun. Use signed char, not 'int',
674 for 'varies' array, so that we needn't bother to check its size
675 calculation for overflow.
676 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
677 * eval.c (apply_lambda):
678 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
679 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
680 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
682 * callint.c (Fcall_interactively): Don't use index var as event count.
684 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
685 * mem-limits.h (SIZE): Remove; no longer used.
687 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
689 Remove unnecessary casts.
690 * xterm.c (x_term_init):
691 * xfns.c (x_set_border_pixel):
692 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
693 These aren't needed now that we assume ANSI C.
695 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
696 It's more likely to cause problems (due to unsigned overflow)
699 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
701 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
703 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
705 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
707 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
709 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
711 GLYPH_CODE_FACE returns EMACS_INT, not int.
712 * dispextern.h (merge_faces):
713 * xfaces.c (merge_faces):
714 * xdisp.c (get_next_display_element, next_element_from_display_vector):
715 Don't assume EMACS_INT fits in int.
717 * character.h (CHAR_VALID_P): Remove unused parameter.
718 * fontset.c, lisp.h, xdisp.c: All uses changed.
720 * editfns.c (Ftranslate_region_internal): Omit redundant test.
722 * fns.c (concat): Minor tuning based on overflow analysis.
723 This doesn't fix any bugs. Use int to hold character, instead
724 of constantly refetching from Emacs object. Use XFASTINT, not
725 XINT, for value known to be a character. Don't bother comparing
726 a single byte to 0400, as it's always less.
728 * floatfns.c (Fexpt):
729 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
731 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
734 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
736 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
737 Without this fix, on a 64-bit host (aset S 0 4294967386) would
738 incorrectly succeed when S was a string, because 4294967386 was
739 truncated before it was used.
741 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
742 Otherwise, an out-of-range integer could cause undefined behavior
745 * composite.c: Use int, not EMACS_INT, for characters.
746 (fill_gstring_body, composition_compute_stop_pos): Use int, not
747 EMACS_INT, for values that are known to be in character range.
748 This doesn't fix any bugs but is the usual style inside Emacs and
749 may generate better code on 32-bit machines.
751 Make sure a 64-bit char is never passed to ENCODE_CHAR.
752 This is for reasons similar to the recent CHAR_STRING fix.
753 * charset.c (Fencode_char): Check that character arg is actually
754 a character. Pass an int to ENCODE_CHAR.
755 * charset.h (ENCODE_CHAR): Verify that the character argument is no
756 wider than 'int', as a compile-time check to prevent future regressions
759 * character.c (char_string): Remove unnecessary casts.
761 Make sure a 64-bit char is never passed to CHAR_STRING.
762 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
763 by silently ignoring the top 32 bits, allowing some values
764 that were far too large to be valid characters.
765 * character.h: Include <verify.h>.
766 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
767 arguments are no wider than unsigned, as a compile-time check
768 to prevent future regressions in this area.
770 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
771 (Fsubst_char_in_region):
773 * xdisp.c (decode_mode_spec_coding):
774 Adjust to CHAR_STRING's new requirement.
775 * editfns.c (Finsert_char, Fsubst_char_in_region):
776 * fns.c (concat): Check that character args are actually
777 characters. Without this test, these functions did the wrong
778 thing with wildly out-of-range values on 64-bit hosts.
780 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
781 These casts should not be needed on 32-bit hosts, either.
782 * keyboard.c (read_char):
783 * lread.c (Fload): Remove casts to unsigned.
785 * lisp.h (UNSIGNED_CMP): New macro.
786 This fixes comparison bugs on 64-bit hosts.
787 (ASCII_CHAR_P): Use it.
788 * casefiddle.c (casify_object):
789 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
790 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
791 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
792 * dispextern.h (FACE_FROM_ID):
793 * keyboard.c (read_char): Use UNSIGNED_CMP.
795 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
796 not to EMACS_INT, to avoid GCC warning.
798 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
800 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
801 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
802 isn't needed on 32-bit machines.
804 * buffer.c (Fgenerate_new_buffer_name):
805 Use EMACS_INT for count, not int.
806 (advance_to_char_boundary): Return EMACS_INT, not int.
808 * data.c (Qcompiled_function): Now static.
810 * window.c (window_body_lines): Now static.
812 * image.c (gif_load): Rename local to avoid shadowing.
814 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
815 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
816 * alloc.c (make_save_value): Integer argument is now of type
818 (mark_object): Use ptrdiff_t, not int.
819 * lisp.h (pD): New macro.
820 * print.c (print_object): Use it.
822 * alloc.c: Use EMACS_INT, not int, to count objects.
823 (total_conses, total_markers, total_symbols, total_vector_size)
824 (total_free_conses, total_free_markers, total_free_symbols)
825 (total_free_floats, total_floats, total_free_intervals)
826 (total_intervals, total_strings, total_free_strings):
827 Now EMACS_INT, not int. All uses changed.
828 (Fgarbage_collect): Compute overall total using a double, so that
829 integer overflow is less likely to be a problem. Check for overflow
830 when converting back to an integer.
831 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
832 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
833 These were 'int' variables that could overflow on 64-bit hosts;
834 they were never used, so remove them instead of repairing them.
835 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
836 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
837 Previously, this ceilinged at INT_MAX, but that doesn't work on
839 (allocate_pseudovector): Don't use EMACS_INT when int would do.
841 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
842 (allocate_vectorlike): Check for ptrdiff_t overflow.
843 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
844 when a (possibly-narrower) signed value would do just as well.
845 We prefer using signed arithmetic, to avoid comparison confusion.
847 * alloc.c: Catch some string size overflows that we were missing.
848 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
849 for convenience in STRING_BYTES_MAX.
850 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
851 The definition here is exact; the one in lisp.h was approximate.
852 (allocate_string_data): Check for string overflow. This catches
853 some instances we weren't catching before. Also, it catches
854 size_t overflow on (unusual) hosts where SIZE_MAX <= min
855 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
856 and ptrdiff_t and EMACS_INT are both 64 bits.
858 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
859 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
860 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
862 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
864 * alloc.c (Fmake_string): Check for out-of-range init.
866 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
868 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
870 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
872 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
873 xg_get_default_scrollbar_width.
875 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
876 (int_gtk_range_get_value): Move to the scroll bar part of the file.
877 (style_changed_cb): Call update_theme_scrollbar_width and call
878 x_set_scroll_bar_default_width and xg_frame_set_char_size for
879 all frames (Bug#8505).
880 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
881 Call gtk_window_set_resizable if HAVE_GTK3.
882 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
883 and height if HAVE_GTK3 (Bug#8505).
884 (scroll_bar_width_for_theme): New variable.
885 (update_theme_scrollbar_width): New function.
886 (xg_get_default_scrollbar_width): Move code to
887 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
888 (xg_initialize): Call update_theme_scrollbar_width.
890 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
892 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
894 2011-06-12 Martin Rudalics <rudalics@gmx.at>
896 * frame.c (make_frame): Call other_buffer_safely instead of
899 * window.c (temp_output_buffer_show): Call display_buffer with
900 second argument Vtemp_buffer_show_specifiers and reset latter
901 immediately after the call.
902 (Vtemp_buffer_show_specifiers): New variable.
903 (auto_window_vscroll_p, next_screen_context_lines)
904 (Vscroll_preserve_screen_position): Remove leading asterisks from
907 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
909 Fix minor problems found by GCC 4.6.0 static checking.
910 * buffer.c (Qclone_number): Remove for now, as it's unused.
911 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
912 (record_buffer): Remove unused local.
913 * frame.c (other_visible_frames, frame_buffer_list): Now static.
914 (set_frame_buffer_list): Remove; unused.
915 * frame.h (other_visible_frames): Remove decl.
916 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
917 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
918 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
920 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
921 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
922 Define only if HAVE_GPM.
923 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
924 (update_hints_inhibit): Remove; never set. All uses removed.
925 * widgetprv.h (emacsFrameClassRec): Remove decl.
926 * window.c (delete_deletable_window): Now returns void, since it
927 wasn't returning anything.
928 (compare_window_configurations): Remove unused locals.
929 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
930 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
931 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
932 the same widths as pointers. This follows up on the 2011-05-06 patch.
933 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
935 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
937 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
939 * makefile.w32-in: Update dependencies.
940 (LISP_H): Add lib/intprops.h.
942 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
944 * image.c (gif_load): Add animation frame delay to the metadata.
945 (syms_of_image): Use DEFSYM. New symbol `delay'.
947 2011-06-11 Martin Rudalics <rudalics@gmx.at>
949 * window.c (delete_deletable_window): Re-add.
950 (Fset_window_configuration): Rewrite to handle dead buffers and
951 consequently deletable windows.
952 (window_tree, Fwindow_tree): Remove. Supply functionality in
954 (compare_window_configurations): Simplify code.
956 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
958 * image.c (imagemagick_load_image): Fix type mismatch.
959 (Fimagemagick_types): Likewise.
961 * window.h (replace_buffer_in_windows): Declare.
963 2011-06-11 Martin Rudalics <rudalics@gmx.at>
965 * buffer.c: New Lisp objects Qbuffer_list_update_hook and

1441 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
1442 it to initialize the frame_window_p member of struct bidi_it.
1443 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
1444 (bidi_resolve_explicit, bidi_resolve_weak)
1445 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
1446 bidi_it->nchars is non-positive.
1447 (bidi_level_of_next_char): Don't try to lookup the cache for the
1448 next/previous character if nothing is cached there yet, or if we
1449 were just reseat()'ed to a new position.
1451 * xdisp.c (set_cursor_from_row): Set start and stop points
1452 according to the row's direction when priming the loop that looks
1453 for the glyph on which to display cursor.
1454 (single_display_spec_intangible_p): Function deleted.
1455 (display_prop_intangible_p): Reimplement to call
1456 handle_display_spec instead of single_display_spec_intangible_p.
1457 Accept 3 additional arguments needed by handle_display_spec.
1458 This fixes incorrect cursor motion across display property with complex
1459 values: lists, `(when COND...)' forms, etc.
1460 (single_display_spec_string_p): Support property values that are
1461 lists with the argument STRING its top-level element.
1462 (display_prop_string_p): Fix the condition for processing a
1463 property that is a list to be consistent with handle_display_spec.
1464 (handle_display_spec): New function, refactored from the
1465 last portion of handle_display_prop.
1466 (compute_display_string_pos): Accept additional argument
1467 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
1468 value of a `display' property is a "replacing spec".
1469 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
1470 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
1471 the display property, but just return a value indicating whether
1472 the display property will replace the characters it covers.
1473 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
1474 frame_window_p members of struct bidi_it.
1475 (compute_display_string_pos, compute_display_string_end):
1477 (push_it): Accept second argument POSITION, where pop_it should
1478 jump to continue iteration.
1479 (reseat_1): Initialize bidi_it.disp_pos.
1481 * keyboard.c (adjust_point_for_property): Adjust the call to
1482 display_prop_intangible_p to its new signature.
1484 * dispextern.h (struct bidi_it): New member frame_window_p.
1485 (bidi_init_it): Update prototypes.
1486 (display_prop_intangible_p): Update prototype.
1487 (compute_display_string_pos, compute_display_string_end):
1489 (struct bidi_it): New members nchars and disp_pos. ch_len is now
1492 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
1494 Malloc failure behavior now depends on size of allocation.
1495 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
1496 * lisp.h: Change signatures accordingly.
1497 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
1498 All callers changed. (Bug#8762)
1500 * gnutls.c: Use Emacs's memory allocators.
1501 Without this change, the gnutls library would invoke malloc etc.
1502 directly, which causes problems on non-SYNC_INPUT hosts, and which
1503 runs afoul of improving memory_full behavior. (Bug#8761)
1504 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
1505 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
1506 xfree instead of the default malloc, realloc, free.
1507 (Fgnutls_boot): No need to check for memory allocation failure,
1508 since xmalloc does that for us.
1510 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
1511 * category.c (hash_get_category_set):
1512 * ccl.c (ccl_driver):
1513 * charset.c (Fdefine_charset_internal):

1524 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
1525 (Fsxhash, Fgethash, Fputhash, Fmaphash):
1526 * image.c (make_image, search_image_cache, lookup_image)
1527 (xpm_put_color_table_h):
1528 * lisp.h (struct Lisp_Hash_Table):
1529 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
1530 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
1531 for hashes and hash indexes, instead of 'unsigned' and 'int'.
1532 * alloc.c (allocate_vectorlike):
1533 Check for overflow in vector size calculations.
1534 * ccl.c (ccl_driver):
1535 Check for overflow when converting EMACS_INT to int.
1536 * fns.c, image.c: Remove unnecessary static decls that would otherwise
1537 need to be updated by these changes.
1538 * fns.c (make_hash_table, maybe_resize_hash_table):
1539 Check for integer overflow with large hash tables.
1540 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
1541 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
1542 (SXHASH_REDUCE): New macro.
1543 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
1544 Use it instead of discarding useful hash info with large hash values.
1545 (sxhash_float): New function.
1546 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
1547 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
1548 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
1549 Rewrite to use FIXNUM_BITS, as this simplifies things.
1550 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
1551 Adjust signatures to match updated version of code.
1552 (consing_since_gc): Now EMACS_INT, since a single hash table can
1553 use more than INT_MAX bytes.
1555 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
1557 Make it possible to build with GCC-4.6+ -O2 -flto.
1559 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
1561 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
1563 * minibuf.c (get_minibuffer, read_minibuf_unwind):
1564 Call minibuffer-inactive-mode.
1566 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
1568 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
1569 Update dependencies.
1571 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1573 * data.c (init_data): Remove code for UTS, this system is not
1576 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1578 Don't force ./temacs to start in terminal mode.
1580 * frame.c (make_initial_frame): Initialize faces in all cases, not
1581 only when CANNOT_DUMP is defined.
1582 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
1584 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1586 * dispnew.c (add_window_display_history): Use const for the string
1587 pointer. Remove declaration, not needed.
1589 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1591 Use 'inline', not 'INLINE'.
1592 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
1593 * alloc.c, fontset.c (INLINE): Remove.
1594 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
1595 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
1596 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
1597 * gmalloc.c (register_heapinfo): Use inline unconditionally.
1598 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
1600 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1602 Make it possible to run ./temacs.
1604 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
1605 syms_of_callproc does the same thing. Remove test for
1606 "initialized", do it in the caller.
1607 * emacs.c (main): Avoid calling set_initial_environment when dumping.
1609 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
1611 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
1612 (read_minibuf): Use get_minibuffer.
1613 (syms_of_minibuf): Use DEFSYM.
1614 (Qmetadata): New var.
1615 * data.c (Qbuffer): Don't make it static.
1616 (syms_of_data): Use DEFSYM.
1618 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1620 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
1621 (CCL_CODE_MIN): New macro.
1623 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
1625 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
1627 * eval.c (Qdebug): Now static.
1628 * lisp.h (Qdebug): Remove decl. This reverts a part of the
1629 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
1630 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
1632 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1634 * image.c: Various fixes to ImageMagick code comments.
1635 (Fimagemagick_types): Doc fix.
1637 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
1639 Minor fixes prompted by GCC 4.6.0 warnings.
1641 * xselect.c (converted_selections, conversion_fail_tag): Now static.
1643 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
1644 (x_clipboard_manager_save_all): Move extern decl to ...
1645 * xterm.h: ... here, so that it can be checked for consistency.
1647 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1649 * xselect.c (x_clipboard_manager_save_frame)
1650 (x_clipboard_manager_save_all): New functions.
1651 (Fx_clipboard_manager_save): Lisp function deleted.
1653 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
1654 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
1656 * xterm.h: Update prototype.
1658 2011-05-28 William Xu <william.xwl@gmail.com>
1660 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
1663 2011-05-28 Jim Meyering <meyering@redhat.com>
1665 Avoid a sign-extension bug in crypto_hash_function.
1666 * fns.c (to_uchar): Define.
1667 (crypto_hash_function): Use it to convert some newly-signed
1668 variables to unsigned, to avoid sign-extension bugs. For example,
1669 without this change, (md5 "truc") would evaluate to
1670 45723a2aff78ff4fff7fff1114760e62 rather than the expected
1671 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
1672 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
1674 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1676 Integer overflow fixes.
1678 * dbusbind.c: Serial number integer overflow fixes.
1679 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
1680 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
1681 to hold a serial number that is too large for a fixnum.
1682 (Fdbus_method_return_internal, Fdbus_method_error_internal):
1683 Check for serial numbers out of range. Decode any serial number
1684 that was so large that it became a float. (Bug#8722)
1686 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
1687 (Fdbus_call_method, Fdbus_call_method_asynchronously):
1688 Use XFASTINT rather than XUINT when numbers are nonnegative.
1689 (xd_append_arg, Fdbus_method_return_internal):
1690 (Fdbus_method_error_internal): Likewise. Also, for unsigned
1691 arguments, check that Lisp number is nonnegative, rather than
1692 silently wrapping negative numbers around. (Bug#8722)
1693 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
1696 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
1698 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
1700 ccl: add integer overflow checks
1701 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
1702 (IN_INT_RANGE): New macros.
1703 (ccl_driver): Use them to check for integer overflow when
1704 decoding a CCL program. Many of the new checks are whether XINT (x)
1705 fits in int; it doesn't always, on 64-bit hosts. The new version
1706 doesn't catch all possible integer overflows, but it's an
1707 improvement. (Bug#8719)
1709 * alloc.c (make_event_array): Use XINT, not XUINT.
1710 There's no need for unsigned here.
1712 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
1713 This follows up to the 2011-05-06 change that substituted uintptr_t
1714 for EMACS_INT. This case wasn't caught back then.
1716 Rework Fformat to avoid integer overflow issues.
1717 * editfns.c: Include <float.h> unconditionally, as it's everywhere
1718 now (part of C89). Include <verify.h>.
1719 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
1720 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
1721 (Fformat): Avoid the prepass trying to compute sizes; it was only
1722 approximate and thus did not catch overflow reliably. Instead, walk
1723 through the format just once, formatting and computing sizes as we go,
1724 checking for integer overflow at every step, and allocating a larger
1725 buffer as needed. Keep track separately whether the format is
1726 multibyte. Keep only the most-recently calculated precision, rather
1727 than them all. Record whether each argument has been converted to
1728 string. Use EMACS_INT, not int, for byte and char and arg counts.
1729 Support field widths and precisions larger than INT_MAX. Avoid
1730 sprintf's undefined behavior with conversion specifications such as %#d
1731 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
1732 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
1733 formatting out-of-range floating point numbers with int
1736 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
1738 * data.c: Avoid integer truncation in expressions involving floats.
1739 * data.c: Include <intprops.h>.
1740 (arith_driver): When there's an integer overflow in an expression
1741 involving floating point, convert the integers to floating point
1742 so that the resulting value does not suffer from catastrophic
1743 integer truncation. For example, on a 64-bit host (* 4
1744 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
1745 Do not rely on undefined behavior after integer overflow.
1747 merge count_size_as_multibyte, parse_str_to_multibyte
1748 * character.c, character.h (count_size_as_multibyte):
1749 Rename from parse_str_to_multibyte; all uses changed.
1750 Check for integer overflow.
1751 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
1752 since it's now a duplicate of the other. This is more of
1753 a character than a buffer op, so better that it's in character.c.
1754 * fns.c, print.c: Adjust to above changes.
1756 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
1758 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
1760 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1762 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1763 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
1764 (x_clipboard_manager_save): Now static.
1765 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
1767 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1768 (crypto_hash_function): Now static.
1769 Fix pointer signedness problems. Avoid unnecessary initializations.
1771 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
1773 * termhooks.h (Vselection_alist): Make it terminal-local.
1775 * terminal.c (create_terminal): Initialize it.
1777 * xselect.c: Support for clipboard managers.
1778 (Vselection_alist): Move to termhooks.h as terminal-local var.

1780 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
1781 (symbol_to_x_atom): Remove gratuitous arg.
1782 (x_handle_selection_request, lisp_data_to_selection_data)
1783 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
1784 (x_own_selection, x_get_local_selection, x_convert_selection):
1785 New arg, specifying work frame. Use terminal-local Vselection_alist.
1786 (some_frame_on_display): Delete unused function.
1787 (Fx_own_selection_internal, Fx_get_selection_internal)
1788 (Fx_disown_selection_internal, Fx_selection_owner_p)
1789 (Fx_selection_exists_p): New optional frame arg.
1790 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
1791 (x_handle_selection_clear): Don't treat other terminals with the
1792 same keyboard specially. Use the terminal-local Vselection_alist.
1793 (x_clear_frame_selections): Use Frun_hook_with_args.
1795 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
1797 * xterm.h: Add support for those atoms.
1799 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
1801 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
1802 (converted_selections, conversion_fail_tag): New global variables.
1803 (x_selection_request_lisp_error): Free the above.
1804 (x_get_local_selection): Remove unnecessary code.
1805 (x_reply_selection_request): Args changed; handle arbitrary array
1806 of converted selections stored in converted_selections.
1807 Separate the XChangeProperty and SelectionNotify steps.
1808 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
1809 (x_convert_selection): New function.
1810 (x_handle_selection_event): Simplify.
1811 (x_get_foreign_selection): Don't ignore incoming requests while
1812 waiting for an answer; this will fail when we implement
1813 SAVE_TARGETS, and seems unnecessary anyway.
1814 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
1815 (Vx_sent_selection_functions): Doc fix.
1817 2011-05-26 Leo Liu <sdl.web@gmail.com>
1819 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
1821 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1823 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
1825 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
1826 for fringe update if it has periodic bitmap.
1827 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
1828 and fringe_bitmap_periodic_p.
1830 * fringe.c (get_fringe_bitmap_data): New function.
1831 (draw_fringe_bitmap_1, update_window_fringes): Use it.
1832 (update_window_fringes): Record periodicity of fringe bitmap in glyph
1833 row. Mark glyph row for fringe update if periodicity changed.
1835 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
1836 for fringe update unless it has periodic bitmap.
1838 2011-05-25 Kenichi Handa <handa@m17n.org>
1840 * xdisp.c (get_next_display_element): Set correct it->face_id for

1857 Remove macros that are defined and never used.
1858 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).

1862 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
1863 (Fx_get_selection_internal): Minor cleanup.
1864 (Fx_own_selection_internal): Rename arguments for consistency with
1867 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1869 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.

1891 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
1893 * systime.h (Time): Define only if emacs is defined.
1894 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
1895 where the include path doesn't have X11/X.h by default. See
1896 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
1898 2011-05-20 Kenichi Handa <handa@m17n.org>
1900 * composite.c (find_automatic_composition): Fix previous change.
1902 2011-05-20 Glenn Morris <rgm@gnu.org>
1904 * lisp.mk: New file, split from Makefile.in.
1905 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
1906 (shortlisp): Remove.
1907 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
1909 2011-05-19 Glenn Morris <rgm@gnu.org>
1911 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
1912 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
1913 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
1914 (lisp): Set the order to that of loadup.el.
1915 (shortlisp): Make it a copy of $lisp.
1916 (SOME_MACHINE_LISP): Remove.
1917 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
1918 Use just $shortlisp, not $SOME_MACHINE_LISP too.
1920 2011-05-18 Kenichi Handa <handa@m17n.org>
1922 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
1923 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
1924 (find_automatic_composition): Mostly rewrite for efficiency.
1926 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
1928 * makefile.w32-in: Update dependencies.
1930 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
1932 * menu.c: Include limits.h (fixes the MS-Windows build broken by
1933 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
1935 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
1937 Fix some integer overflow issues, such as string length overflow.
1939 * insdel.c (count_size_as_multibyte): Check for string overflow.
1941 * character.c (lisp_string_width): Check for string overflow.
1942 Use EMACS_INT, not int, for string indexes and lengths; in
1943 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
1944 the resulting string length overflows an EMACS_INT; instead,
1945 report a string overflow if no precision given. When checking for
1946 precision exhaustion, use a check that cannot possibly have
1947 integer overflow. (Bug#8675)
1948 * character.h (lisp_string_width): Adjust to new signature.
1950 * alloc.c (string_overflow): New function.
1951 (Fmake_string): Use it. This doesn't change behavior, but saves
1952 a few bytes and will simplify future changes.
1953 * character.c (string_escape_byte8): Likewise.
1954 * lisp.h (string_overflow): New decl.
1956 Fixups, following up to the user-interface timestamp change.
1957 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
1958 for UI timestamps, instead of unsigned long.
1959 * msdos.c (mouse_get_pos): Likewise.
1960 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
1961 * w32gui.h (Time): Define by including "systime.h" rather than by
1962 declaring it ourselves. (Bug#8664)
1964 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
1965 * image.c (clear_image_cache): Likewise.
1967 * term.c (term_mouse_position): Don't assume time_t wraparound.
1969 Be more systematic about user-interface timestamps.
1970 Before, the code sometimes used 'Time', sometimes 'unsigned long',
1971 and sometimes 'EMACS_UINT', to represent these timestamps.
1972 This change causes it to use 'Time' uniformly, as that's what X uses.
1973 This makes the code easier to follow, and makes it easier to catch
1974 integer overflow bugs such as Bug#8664.
1975 * frame.c (Fmouse_position, Fmouse_pixel_position):
1976 Use Time, not unsigned long, for user-interface timestamps.
1977 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
1978 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
1979 * keyboard.h (last_event_timestamp): Likewise.
1980 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
1981 * menu.h (xmenu_show): Likewise.
1982 * term.c (term_mouse_position): Likewise.
1983 * termhooks.h (struct input_event.timestamp): Likewise.
1984 (struct terminal.mouse_position_hook): Likewise.
1985 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
1986 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
1987 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
1988 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
1990 * menu.h, termhooks.h: Include "systime.h", for Time.
1992 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
1993 Don't assume that the difference between two unsigned long values
1994 can fit into an integer. At this point, we know button_down_time
1995 <= event->timestamp, so the difference must be nonnegative, so
1996 there's no need to cast the result if double-click-time is
1997 nonnegative, as it should be; check that it's nonnegative, just in
1998 case. This bug is triggered when events are more than 2**31 ms
1999 apart (about 25 days). (Bug#8664)
2001 * xselect.c (last_event_timestamp): Remove duplicate decl.
2002 (x_own_selection): Remove needless cast to unsigned long.
2004 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
2005 that always fit in int. Use a sentinel instead of a counter, to
2006 avoid a temp and to allay GCC's concerns about possible int overflow.
2007 * frame.h (struct frame): Use int for menu_bar_items_used
2008 instead of EMACS_INT, since it always fits in int.
2010 * menu.c (grow_menu_items): Check for int overflow.
2012 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
2014 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
2015 Before, the code was not consistent. These values cannot exceed
2016 2**31 - 1 so there's no need to make them unsigned.
2017 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
2018 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
2019 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
2021 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
2023 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
2024 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
2025 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
2026 presumably because the widths might not match.
2028 * window.c (size_window): Avoid needless test at loop start.
2030 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
2032 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
2034 2011-05-12 Drew Adams <drew.adams@oracle.com>
2036 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
2038 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2040 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
2041 `width' to `bar_area_x' and `bar_area_width', respectively.
2042 (x_scroll_run): Take account of fringe background extension.
2044 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
2045 Rename local vars `left' and `width' to `bar_area_x' and
2046 `bar_area_width', respectively.
2047 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
2048 background extension.
2050 2011-05-10 Jim Meyering <meyering@redhat.com>
2052 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
2054 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
2056 * image.c (Finit_image_library): Return t for built-in image types,
2057 like pbm and xbm. (Bug#8640)
2059 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
2061 * w32menu.c (set_frame_menubar): Fix submenu allocation.
2063 2011-05-07 Eli Zaretskii <eliz@gnu.org>
2065 * w32console.c (Fset_screen_color): Doc fix.
2066 (Fget_screen_color): New function.
2067 (syms_of_ntterm): Defsubr it.
2069 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
2070 unlink the temporary file if Fcall_process didn't create it in the
2072 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
2073 child process will be redirected to a file specified with `:file'.
2074 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
2075 cue to call_process_cleanup not to close that handle.
2077 2011-05-07 Ben Key <bkey76@gmail.com>
2079 * makefile.w32-in: The bootstrap-temacs rule now makes use of
2080 one of two shell specific rules, either bootstrap-temacs-CMD or
2081 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
2082 to the previous implementation of the bootstrap-temacs rule.
2083 The bootstrap-temacs-CMD rule is similar to the previous
2084 implementation of the bootstrap-temacs rule except that it
2085 makes use of the ESC_CFLAGS variable instead of the CFLAGS
2088 These changes, along with some changes to nt/configure.bat,
2089 nt/gmake.defs, and nt/nmake.defs, are required to extend my
2090 earlier fix to add support for --cflags and --ldflags options
2091 that include quotes so that it works whether make uses cmd or
2094 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
2096 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
2097 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
2099 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
2100 a string. Handle both cases.
2101 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
2102 (Fdbus_register_method): Use Qinvalid_function.
2104 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
2106 * makefile.w32-in: Update dependencies.
2107 (LISP_H): Add inttypes.h and stdin.h.
2108 (PROCESS_H): Add unistd.h.
2110 2011-05-06 Eli Zaretskii <eliz@gnu.org>
2112 * lread.c: Include limits.h (fixes the MS-Windows build broken by
2113 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
2115 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
2117 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
2119 * term.c (vfatal): Remove stray call to va_end.
2120 It's not needed and the C Standard doesn't allow it here anyway.
2122 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
2123 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
2125 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
2128 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
2130 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
2132 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
2134 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
2136 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
2138 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
2139 * charset.c (Fdefine_charset_internal): Don't initialize
2140 charset.code_space[15]. The value was garbage, on hosts with
2141 32-bit int (Bug#8600).
2143 * lread.c (read_integer): Be more consistent with string-to-number.
2144 Use string_to_number to do the actual conversion; this avoids
2145 rounding errors and fixes some other screwups. Without this fix,
2146 for example, #x1fffffffffffffff was misread as -2305843009213693952.
2147 (digit_to_number): Move earlier, for benefit of read_integer.
2148 Return -1 if the digit is out of range for the base, -2 if it is
2149 not a digit in any supported base. (Bug#8602)
2151 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
2153 * dispnew.c (scrolling_window): Return 1 if we scrolled,
2154 to match comment at start of function. This also removes a
2155 GCC warning about overflow in a 32+64-bit port.
2157 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
2159 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
2160 Reported by Stefan Monnier in
2161 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
2162 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2163 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
2165 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
2166 (EMACS_UINTPTR): Likewise, with uintptr_t.
2168 * lisp.h: Prefer 64-bit EMACS_INT if available.
2169 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
2170 on 32-bit hosts that have 64-bit int, so that they can access
2172 However, temporarily disable this change unless the temporary
2173 symbol WIDE_EMACS_INT is defined.
2175 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
2177 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
2178 This removes an assumption that EMACS_INT and long are the same
2179 width as pointers. The assumption is true for Emacs porting targets
2180 now, but we want to make other targets possible.
2181 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
2182 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
2183 In the rest of the code, change types of integers that hold casted
2184 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
2185 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
2186 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
2187 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
2188 No need to cast type when ORing.
2189 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
2190 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
2191 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
2192 assume EMACS_INT is the same width as char *.
2193 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
2194 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
2195 Remove no-longer-needed casts.
2196 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
2197 (xg_tool_bar_help_callback, xg_make_tool_item):
2198 Use EMACS_INTPTR to hold an integer
2199 that will be cast to void *; this can avoid a GCC warning
2200 if EMACS_INT is not the same width as void *.
2201 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
2202 * xdisp.c (display_echo_area_1, resize_mini_window_1):
2203 (current_message_1, set_message_1):
2204 Use a local to convert to proper width without a cast.
2205 * xmenu.c (dialog_selection_callback): Likewise.
2207 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
2208 Also, don't assume VALBITS / RAND_BITS is less than 5,
2209 and don't rely on undefined behavior when shifting a 1 left into
2211 * lisp.h (get_random): Change signature to match.
2213 * lread.c (hash_string): Use size_t, not int, for hash computation.
2214 Normally we prefer signed values; but hashing is special, because
2215 it's better to use unsigned division on hash table sizes so that
2216 the remainder is nonnegative. Also, size_t is the natural width
2217 for hashing into memory. The previous code used 'int', which doesn't
2218 retain enough info to hash well into very large tables.
2219 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
2221 * dbusbind.c: Don't possibly lose pointer info when converting.
2222 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2223 Use XPNTR rather than XHASH, so that the high-order bits of
2224 the pointer aren't lost when converting through void *.
2226 * eval.c (Fautoload): Don't double-shift a pointer.
2228 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
2230 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
2232 * gnutls.c (DEF_GNUTLS_FN):
2233 * image.c (DEF_IMGLIB_FN): Make function pointers static.
2235 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
2237 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
2240 2011-05-05 Eli Zaretskii <eliz@gnu.org>
2242 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
2243 New version that can reserve upto 2GB of heap space.
2245 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
2247 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
2249 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
2251 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
2252 `gnutls_certificate_set_x509_key_file'.
2254 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
2256 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
2257 Update dependencies.
2259 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2261 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
2262 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
2263 Remove unused parameter `fildes'.
2264 * process.c (read_process_output, send_process): Don't pass it.
2266 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2268 Fix previous change: the library cache is defined in w32.c.
2269 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
2270 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
2272 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2274 Implement dynamic loading of GnuTLS on Windows.
2276 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
2277 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
2278 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
2281 * gnutls.c (Qgnutls_dll): Define.
2282 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
2283 (gnutls_*): Declare function pointers.
2284 (init_gnutls_functions): New function to initialize function pointers.
2285 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
2286 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
2287 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
2288 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
2289 (emacs_gnutls_write, emacs_gnutls_read)
2290 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
2291 (Fgnutls_available_p): New function.
2292 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
2293 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
2294 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
2296 * image.c: Include w32.h.
2297 (Vimage_type_cache): Delete.
2298 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
2299 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
2300 (w32_delayed_load): Move to w32.c.
2302 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
2304 * w32.c (QCloaded_from, Vlibrary_cache): Define.
2305 (w32_delayed_load): Move from image.c. When loading a library, record
2306 its filename in the :loaded-from property of the library id.
2307 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
2308 Initialize and staticpro them.
2309 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
2311 * process.c: Include lisp.h before w32.h, not after.
2312 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
2313 instead of gnutls_record_check_pending.
2315 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
2317 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
2319 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
2320 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
2323 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
2325 * xterm.c (x_set_frame_alpha): Do not set property on anything

2360 (Fcall_process_region): Ditto.
2362 2011-04-30 Eli Zaretskii <eliz@gnu.org>
2364 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
2365 rather than `XVECTOR (FOO)->size'.
2367 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
2368 inttypes.h, as a gnulib replacement is used if it not available in

2375 of MOST_POSITIVE_FIXNUM. (Bug#8528)
2377 * coding.c (coding_alloc_by_realloc): Error out if destination
2378 will grow beyond MOST_POSITIVE_FIXNUM.
2379 (decode_coding_emacs_mule): Abort if there isn't enough place in
2380 charbuf for the composition carryover bytes. Reserve an extra
2381 space for up to 2 characters produced in a loop.
2382 (decode_coding_iso_2022): Abort if there isn't enough place in
2383 charbuf for the composition carryover bytes.
2385 2011-04-21 Eli Zaretskii <eliz@gnu.org>
2387 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
2388 aborting when %lld or %lll format is passed.
2389 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
2390 %llo or %llx format is passed. (Bug#8545)
2392 * window.c (window_scroll_line_based): Use a marker instead of
2393 simple variables to record original value of point. (Bug#7952)
2395 * doprnt.c (doprnt): Fix the case where a multibyte sequence
2396 produced by %s or %c overflows available buffer space. (Bug#8545)
2398 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
2400 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
2401 (SIZE_MAX): Move defn after all includes, as they might #define it.
2403 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2405 * w32.c (init_environment): Warn about defaulting HOME to C:\.
2407 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2409 * keyboard.c (Qdelayed_warnings_hook): Define.
2410 (command_loop_1): Run `delayed-warnings-hook'
2411 if Vdelayed_warnings_list is non-nil.
2412 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
2413 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
2415 2011-04-28 Eli Zaretskii <eliz@gnu.org>
2417 * doprnt.c (doprnt): Don't return value smaller than the buffer
2418 size if the message was truncated. (Bug#8545).
2420 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2422 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

2425 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
2427 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
2429 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
2431 * makefile.w32-in: Update dependencies.
2433 2011-04-27 Eli Zaretskii <eliz@gnu.org>
2435 Improve `doprnt' and its usage. (Bug#8545)
2436 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
2437 `format_end'. Remove support for %l as a conversion specifier.
2438 Don't use xrealloc. Improve diagnostics when the %l size modifier
2439 is used. Update the commentary.
2441 * eval.c (verror): Simplify calculation of size_t.
2443 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
2446 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
2448 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
2451 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
2453 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
2454 This makes this file independent of the recent pseudovector change.
2456 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
2458 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
2460 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
2461 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
2462 Remove unused local.
2463 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
2465 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
2466 GCC 4.6.0 optimizes based on type-based alias analysis.
2467 For example, if b is of type struct buffer * and v of type struct
2468 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
2469 != &v->size, and therefore "v->size = 1; b->size = 2; return
2470 v->size;" must therefore return 1. This assumption is incorrect
2471 for Emacs, since it type-puns struct Lisp_Vector * with many other
2472 types. To fix this problem, this patch adds a new type struct
2473 vectorlike_header that documents the constraints on layout of vectors
2474 and pseudovectors, and helps optimizing compilers not get fooled
2475 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
2476 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
2477 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
2479 (XSETPVECTYPE): Rewrite in terms of new macro.
2480 (XSETPVECTYPESIZE): New macro, specifying both type and size.
2481 This is a bit clearer, and further avoids the possibility of
2482 undesirable aliasing.
2483 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
2484 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
2485 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
2486 since Lisp_Subr is a special case (no "next" field).
2487 (ASIZE): Now uses header.size rather than size.
2488 All previous uses of XVECTOR (foo)->size replaced to use this macro,
2489 to avoid the hassle of writing XVECTOR (foo)->header.size.
2490 (struct vectorlike_header): New type.
2491 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
2492 object, to help avoid aliasing.
2493 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
2494 (SUBRP): Likewise, since Lisp_Subr is a special case.
2495 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
2496 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
2497 (struct Lisp_Hash_Table): Combine first two members into a single
2498 struct vectorlike_header member. All uses of "size" and "next" members
2499 changed to be "header.size" and "header.next".
2500 * buffer.h (struct buffer): Likewise.
2501 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
2502 * frame.h (struct frame): Likewise.
2503 * process.h (struct Lisp_Process): Likewise.
2504 * termhooks.h (struct terminal): Likewise.
2505 * window.c (struct save_window_data, struct saved_window): Likewise.
2506 * window.h (struct window): Likewise.
2507 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
2508 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
2509 * buffer.c (init_buffer_once): Likewise.
2510 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
2512 * process.c (Fformat_network_address): Use local var for size,
2515 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
2517 Make the Lisp reader and string-to-float more consistent (Bug#8525)
2518 * data.c (atof): Remove decl; no longer used or needed.
2519 (digit_to_number): Move to lread.c.
2520 (Fstring_to_number): Use new string_to_number function, to be
2521 consistent with how the Lisp reader treats infinities and NaNs.
2522 Do not assume that floating-point numbers represent EMACS_INT
2523 without losing information; this is not true on most 64-bit hosts.
2524 Avoid double-rounding errors, by insisting on integers when
2525 parsing non-base-10 numbers, as the documentation specifies.
2526 * lisp.h (string_to_number): New decl, replacing ...
2527 (isfloat_string): Remove.
2528 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
2529 (read1): Do not accept +. and -. as integers; this
2530 appears to have been a coding error. Similarly, do not accept
2531 strings like +-1e0 as floating point numbers. Do not report
2532 overflow for integer overflows unless the base is not 10 which
2533 means we have no simple and reliable way to continue.
2534 Break out the floating-point parsing into a new
2535 function string_to_number, so that Fstring_to_number parses
2536 floating point numbers consistently with the Lisp reader.
2537 (digit_to_number): Move here from data.c. Make it static inline.
2538 (E_CHAR, EXP_INT): Remove, replacing with ...
2539 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
2540 (string_to_number): New function, replacing isfloat_string.
2541 This function checks for valid syntax and produces the resulting
2542 Lisp float number too. Rework it so that string-to-number
2543 no longer mishandles examples like "1.0e+". Use strtoumax,
2544 so that overflow for non-base-10 numbers is reported only when
2545 there's no portable and simple way to convert to floating point.
2547 * textprop.c (set_text_properties_1): Rewrite for clarity,
2548 and to avoid GCC warning about integer overflow.
2550 * intervals.h (struct interval): Use EMACS_INT for members
2551 where EMACS_UINT might cause problems. See
2552 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
2553 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
2554 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
2556 (offset_intervals): Tell GCC not to worry about length overflow
2557 when negating a negative length.
2559 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
2560 (overrun_check_free): Likewise.
2562 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
2563 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
2566 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2567 (gnutls_make_error): Rename local to avoid shadowing.
2568 (gnutls_emacs_global_deinit): ifdef out; not used.
2569 (Fgnutls_boot): Use const for pointer to readonly storage.
2570 Comment out unused local. Fix pointer signedness problems.
2572 * lread.c (openp): Don't stuff size_t into an 'int'.
2573 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
2574 about possible signed overflow.
2576 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2577 (GDK_KEY_g): Don't define if already defined.
2578 (xg_prepare_tooltip): Avoid pointer signedness problem.
2579 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
2581 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
2582 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
2584 * xfns.c (Fx_window_property): Simplify a bit,
2585 to make a bit faster and to avoid GCC 4.6.0 warning.
2586 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
2588 * fns.c (internal_equal): Don't assume size_t fits in int.
2590 * alloc.c (compact_small_strings): Tighten assertion a little.
2592 Replace pEd with more-general pI, and fix some printf arg casts.
2593 * lisp.h (pI): New macro, generalizing old pEd macro to other
2594 conversion specifiers. For example, use "...%"pI"d..." rather
2595 than "...%"pEd"...".
2596 (pEd): Remove. All uses replaced with similar uses of pI.
2597 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
2598 * alloc.c (check_pure_size): Don't overflow by converting size to int.
2599 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
2600 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
2601 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
2602 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
2603 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
2605 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
2606 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
2607 * print.c (safe_debug_print, print_object): Likewise.
2608 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
2610 Use pI instead of if-then-else-abort. Use %p to avoid casts,
2611 avoiding the 0 flag, which is not portable.
2612 * process.c (Fmake_network_process): Use pI to avoid cast.
2613 * region-cache.c (pp_cache): Likewise.
2614 * xdisp.c (decode_mode_spec): Likewise.
2615 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
2616 behavior on 64-bit hosts with printf arg.
2617 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
2618 (x_stop_queuing_selection_requests): Likewise.
2619 (x_get_window_property): Don't truncate byte count to an 'int'
2622 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
2623 here, since it parses constructs like leading '-' and spaces,
2624 which are not wanted; and it overflows with large numbers.
2625 Instead, simply match F[0-9]+, which is what is wanted anyway.
2627 * alloc.c: Remove unportable assumptions about struct layout.
2628 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
2629 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
2630 (allocate_vectorlike, make_pure_vector): Use the new macros,
2631 plus offsetof, to remove unportable assumptions about struct layout.
2632 These assumptions hold on all porting targets that I know of, but
2633 they are not guaranteed, they're easy to remove, and removing them
2634 makes further changes easier.
2636 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
2637 This doesn't fix a bug but makes the code clearer.
2638 (string_overrun_cookie): Now const. Use initializers that
2639 don't formally overflow signed char, to avoid warnings.
2640 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
2641 can cause Emacs to crash when string overrun checking is enabled.
2642 (allocate_buffer): Don't assume sizeof (struct buffer) is a
2643 multiple of sizeof (EMACS_INT); it need not be, if
2644 alignof(EMACS_INT) < sizeof (EMACS_INT).
2645 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
2647 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
2649 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
2651 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>

2667 * alloc.c (check_sblock, check_string_bytes)
2668 (check_string_free_list): Convert to standard C.
2670 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
2672 * w32.c (emacs_gnutls_push): Fix typo.
2674 2011-04-25 Eli Zaretskii <eliz@gnu.org>
2676 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
2677 "cast to pointer from integer of different size".
2679 Improve doprnt and its use in verror. (Bug#8545)
2680 * doprnt.c (doprnt): Document the set of format control sequences
2681 supported by the function. Use SAFE_ALLOCA instead of always
2684 * eval.c (verror): Don't limit the buffer size at size_max-1, that
2685 is one byte too soon. Don't use xrealloc; instead xfree and
2688 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
2690 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
2693 * gnutls.c: Renamed global_initialized to
2694 gnutls_global_initialized. Added internals for the
2695 :verify-hostname-error, :verify-error, and :verify-flags
2696 parameters of `gnutls-boot' and documented those parameters in the
2697 docstring. Start callback support.
2698 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
2699 unless a fatal error occured. Call gnutls_alert_send_appropriate
2700 on error. Return error code.
2701 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
2702 (emacs_gnutls_read): Likewise.
2703 (Fgnutls_boot): Return handshake error code.
2704 (emacs_gnutls_handle_error): New function.
2705 (wsaerror_to_errno): Likewise.
2707 * w32.h (emacs_gnutls_pull): Add prototype.
2708 (emacs_gnutls_push): Likewise.
2710 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
2711 (emacs_gnutls_push): Likewise.
2713 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
2715 * process.c (wait_reading_process_output): Check if GnuTLS
2716 buffered some data internally if no FDs are set for TLS

2720 (LIBS): Link to USER_LIBS.
2721 ($(BLD)/gnutls.$(0)): New target.
2723 2011-04-24 Eli Zaretskii <eliz@gnu.org>

2742 to changes in oldXMenu/XMenu.h from 2011-04-16.
2743 (struct XMenu): Declare `help_text' `const char **'.

2772 * doprnt.c: Include limits.h.
2773 (SIZE_MAX): New macro.
2774 (doprnt): Return a size_t value. 2nd arg is now size_t.
2775 Many local variables are now size_t instead of int or unsigned.
2776 Improve overflow protection. Support `l' modifier for integer
2777 conversions. Support %l conversion. Don't assume an EMACS_INT
2778 argument for integer conversions and for %c.

3498 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
3499 since callers should never pass a negative size.
3500 Change the signature to match that of plain 'read' and 'write'; see
3501 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
3502 * lisp.h: Update prototypes of emacs_write and emacs_read.
3504 2011-04-11 Eli Zaretskii <eliz@gnu.org>
3506 * xdisp.c (redisplay_window): Don't try to determine the character
3507 position of the scroll margin if the window start point w->startp
3508 is outside the buffer's accessible region. (Bug#8468)
3510 2011-04-10 Eli Zaretskii <eliz@gnu.org>
3512 Fix write-region and its subroutines for buffers > 2GB.
3513 * fileio.c (a_write, e_write): Modify declaration of arguments and
3514 local variables to support buffers larger than 2GB.
3515 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
3517 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
3518 argument, local variables, and return value.
3520 * lisp.h: Update prototypes of emacs_write and emacs_read.
3522 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
3524 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
3526 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
3528 Fix more problems found by GCC 4.6.0's static checks.
3530 * xdisp.c (vmessage): Use a better test for character truncation.
3532 * charset.c (load_charset_map): <, not <=, for optimization,
3533 and to avoid potential problems with integer overflow.
3534 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
3535 * casetab.c (set_identity, shuffle): Likewise.
3536 * editfns.c (Fformat): Likewise.
3537 * syntax.c (skip_chars): Likewise.
3539 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
3540 This also lets GCC 4.6.0 generate slightly better loop code.
3542 * callint.c (Fcall_interactively): <, not <=, for optimization.
3543 (Fcall_interactively): Count the number of arguments produced,
3544 not the number of arguments given. This is simpler and lets GCC
3545 4.6.0 generate slightly better code.
3547 * ftfont.c: Distingish more carefully between FcChar8 and char.
3548 The previous code passed unsigned char * to a functions like
3549 strlen and xstrcasecmp that expect char *, which does not
3550 conform to the C standard.
3551 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
3552 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
3553 char * when the C standard requires it.
3555 * keyboard.c (read_char): Remove unused var.
3557 * eval.c: Port to Windows vsnprintf (Bug#8435).
3559 (SIZE_MAX): Define if the headers do not.
3560 (verror): Do not give up if vsnprintf returns a negative count.
3561 Instead, grow the buffer. This ports to Windows vsnprintf, which
3562 does not conform to C99. Problem reported by Eli Zaretskii.
3563 Also, simplify the allocation scheme, by avoiding the need for
3564 calling realloc, and removing the ALLOCATED variable.
3566 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
3568 Remove invocations of doprnt, as Emacs now uses vsnprintf.
3569 But keep the doprint source code for now, as we might revamp it
3570 and use it again (Bug#8435).
3571 * lisp.h (doprnt): Remove.
3572 * Makefile.in (base_obj): Remove doprnt.o.
3573 * deps.mk (doprnt.o): Remove.
3575 error: Print 32- and 64-bit integers portably (Bug#8435).
3576 Without this change, on typical 64-bit hosts error ("...%d...", N)
3577 was used to print both 32- and 64-bit integers N, which relied on
3579 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
3581 * lisp.h (error, verror): Mark as printf-like functions.
3582 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
3583 Report overflow in size calculations when allocating printf buffer.
3584 Do not truncate output string at its first null byte.
3585 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
3586 Truncate the output at a character boundary, since vsnprintf does not
3588 * charset.c (check_iso_charset_parameter): Convert internal
3589 character to string before calling 'error', since %c now has the
3591 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
3592 overflow when computing char to be passed to 'error'. Do not
3593 pass Lisp_Object to 'error'; pass the integer instead.
3594 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
3595 formatted with plain %d.
3597 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
3599 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
3601 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
3603 * xterm.c (x_catch_errors): Remove duplicate declaration.
3605 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
3607 * xdisp.c, lisp.h (message_nolog): Remove; unused.
3609 2011-04-10 Jim Meyering <meyering@redhat.com>
3611 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
3612 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
3613 return ssize_t not "int", and use size_t as the buffer length.
3614 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
3615 * gnutls.h: Update declarations.
3616 * process.c (read_process_output): Use ssize_t, to match.
3617 (send_process): Likewise.
3619 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3621 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
3623 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3625 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
3626 Use unsigned char, to match FcChar8 type definition.
3628 * xterm.c (handle_one_xevent):
3629 * xmenu.c (create_and_show_popup_menu):
3630 * xselect.c (x_decline_selection_request)
3631 (x_reply_selection_request): Avoid type-punned deref of X events.
3633 2011-04-09 Eli Zaretskii <eliz@gnu.org>
3635 Fix some uses of `int' instead of EMACS_INT.
3636 * search.c (string_match_1, fast_string_match)
3637 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
3638 (scan_buffer, find_next_newline_no_quit)
3639 (find_before_next_newline, search_command, Freplace_match)
3640 (Fmatch_data): Make some `int' variables be EMACS_INT.
3642 * xdisp.c (display_count_lines): 3rd argument and return value now
3643 EMACS_INT. All callers changed.
3644 (pint2hrstr): Last argument is now EMACS_INT.
3646 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)

3663 (encode_invocation_designation): Last argument P_NCHARS is now
3665 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
3666 (produce_chars): from_nchars and to_nchars are now EMACS_INT.

3686 2011-04-08 Chong Yidong <cyd@stupidchicken.com>

3706 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
3708 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
3710 Fix more problems found by GCC 4.6.0's static checks.
3712 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
3714 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
3716 * lisp.h (message, message_nolog, fatal): Mark as printf-like.

3729 * eval.c (Fsignal): Remove excess argument to 'fatal'.
3731 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
3732 This avoids several warnings with gcc -Wstrict-overflow.
3733 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
3734 directly, rather than having caller test rule sign. This avoids
3735 some unnecessary tests.
3736 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
3737 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
3738 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
3740 * xfont.c (xfont_text_extents): Remove var that was set but not used.
3741 (xfont_open): Avoid unnecessary tests.
3743 * composite.c (composition_gstring_put_cache): Use unsigned integer.
3745 * composite.h, composite.c (composition_gstring_put_cache):
3746 Use EMACS_INT, not int, for length.
3748 * composite.h (COMPOSITION_DECODE_REFS): New macro,
3749 breaking out part of COMPOSITION_DECODE_RULE.
3750 (COMPOSITION_DECODE_RULE): Use it.
3751 * composite.c (get_composition_id): Remove unused local vars,
3752 by using the new macro.
3754 * textprop.c (set_text_properties_1): Change while to do-while,
3755 since the condition is always true at first.
3757 * intervals.c (graft_intervals_into_buffer): Mark var as used.
3758 (interval_deletion_adjustment): Return unsigned value.
3761 * process.c (list_processes_1, create_pty, read_process_output):

3763 (create_pty): Remove unnecessary "volatile"s.
3764 (Fnetwork_interface_info): Avoid possibility of int overflow.

3770 * syntax.c (scan_words): Remove var that was set but not used.
3771 (update_syntax_table): Use unsigned instead of int.
3773 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

3780 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
3782 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
3783 (font_score): Avoid potential overflow in diff calculation.

3786 (sxhash): Redo loop for clarity and to avoid wraparound warning.
3788 * eval.c (funcall_lambda): Rename local to avoid shadowing.
3790 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
3791 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
3792 can always succeed if overflow has undefined behavior.
3794 * search.c (boyer_moore, wordify): Remove vars set but not used.
3795 (wordify): Omit three unnecessary tests.
3797 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
3798 All callers changed. This avoids the need for an unused var.
3800 * casefiddle.c (casify_region): Remove var that is set but not used.
3802 * dired.c (file_name_completion): Remove var that is set but not used.
3804 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
3806 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
3807 (Finsert_file_contents): Remove unnecessary code checking fd.
3809 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
3810 Check for integer overflow on size calculations.
3812 * buffer.c (Fprevious_overlay_change): Remove var that is set
3815 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
3816 Remove vars that are set but not used.
3817 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
3818 (timer_check_2): Mark vars as initialized.
3820 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
3822 * image.c (lookup_image): Remove var that is set but not used.
3823 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
3825 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
3826 that are set but not used.
3828 * xfns.c (make_invisible_cursor): Don't return garbage
3829 if XCreateBitmapFromData fails (Bug#8410).
3831 * xselect.c (x_get_local_selection, x_handle_property_notify):
3832 Remove vars that are set but not used.
3834 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
3835 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
3837 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
3838 Remove var that is set but not used.
3839 (scroll_bar_windows_size): Now size_t, not int.
3840 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
3843 * xfaces.c (realize_named_face): Remove vars that are set but not used.
3844 (map_tty_color) [!defined MSDOS]: Likewise.
3846 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
3848 * coding.c: Remove vars that are set but not used.
3849 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
3850 All callers changed.
3851 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
3852 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
3853 (decode_coding_charset): Remove vars that are set but not used.
3855 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
3856 that is set but not used.
3858 * print.c (print_object): Remove var that is set but not used.
3860 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
3861 The gnulib version avoids calling malloc in the usual case,
3862 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
3863 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
3864 * filelock.c (current_lock_owner): Likewise.
3865 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
3866 * sysdep.c: Include allocator.h, careadlinkat.h.
3867 (emacs_no_realloc_allocator): New static constant.
3868 (emacs_readlink): New function.
3869 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

3872 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
3874 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
3875 first non-nil return value).
3877 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
3879 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
3880 if not defined (Bug#8403).
3882 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
3884 * xdisp.c (display_count_lines): Remove parameter `start',
3885 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3886 (get_char_face_and_encoding): Remove parameter `multibyte_p',
3887 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

3889 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
3890 and thereabouts. All callers changed.
3891 (get_per_char_metric): Remove parameter `f', unused since
3892 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
3894 2011-04-02 Jim Meyering <meyering@redhat.com>
3896 do not dereference NULL upon failed strdup
3897 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
3898 (ns_get_family): Likewise.
3900 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
3902 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
3904 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
3906 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
3909 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
3911 Add lexical binding.
3913 * window.c (Ftemp_output_buffer_show): New fun.
3914 (Fsave_window_excursion):
3915 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
3917 * lread.c (lisp_file_lexically_bound_p): New function.
3918 (Fload): Bind Qlexical_binding.
3919 (readevalloop): Remove `evalfun' arg.
3920 Bind Qinternal_interpreter_environment.
3921 (Feval_buffer): Bind Qlexical_binding.
3922 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
3924 (syms_of_lread): Declare `lexical-binding'.
3926 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
3928 * keyboard.c (eval_dyn): New fun.
3929 (menu_item_eval_property): Use it.
3931 * image.c (parse_image_spec): Use Ffunctionp.
3933 * fns.c (concat, mapcar1): Accept byte-code-functions.
3935 * eval.c (Fsetq): Handle lexical vars.
3936 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
3937 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
3938 (FletX, Flet): Obey lexical binding.
3939 (Fcommandp): Handle closures.
3940 (Feval): New `lexical' arg.
3941 (eval_sub): New function extracted from Feval. Use it almost
3942 everywhere where Feval was used. Look up vars in lexical env.
3944 (Ffunctionp): Move from subr.el.
3945 (Ffuncall): Handle closures.
3946 (apply_lambda): Remove `eval_flags'.
3947 (funcall_lambda): Handle closures and new byte-code-functions.
3948 (Fspecial_variable_p): New function.
3949 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
3950 but without exporting it to Lisp.
3952 * doc.c (Fdocumentation, store_function_docstring):
3953 * data.c (Finteractive_form): Handle closures.
3955 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
3958 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
3960 (exec_byte_code): New function extracted from Fbyte_code to handle new
3961 calling convention for byte-code-functions. Add new byte-codes.
3963 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
3965 * alloc.c (Fmake_symbol): Init new `declared_special' field.
3967 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
3969 * xdisp.c (redisplay_internal): Fix prototype.
3971 2011-03-31 Eli Zaretskii <eliz@gnu.org>
3973 * xdisp.c (SCROLL_LIMIT): New macro.
3974 (try_scrolling): Use it when setting scroll_limit.
3975 Limit scrolling to 100 screen lines.
3976 (redisplay_window): Even when falling back on "recentering",
3977 position point in the window according to scroll-conservatively,
3978 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
3980 (try_scrolling): When point is above the window, allow searching
3981 as far as scroll_max, or one screenful, to compute vertical
3982 distance from PT to the scroll margin position. This prevents
3983 try_scrolling from unnecessarily failing when
3984 scroll-conservatively is set to a value slightly larger than the
3985 window height. Clean up the case of PT below the margin at bottom
3986 of window: scroll_max can no longer be INT_MAX. When aggressive
3987 scrolling is in use, don't let point enter the opposite scroll
3988 margin as result of the scroll.
3989 (syms_of_xdisp) <scroll-conservatively>: Document the
3990 threshold of 100 lines for never-recentering scrolling.
3992 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
3994 * dispextern.h (move_it_by_lines):
3995 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
3996 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
3997 (message_log_check_duplicate): Remove parameters `prev_bol' and
3998 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3999 (redisplay_internal): Remove parameter `preserve_echo_area',
4000 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
4002 * indent.c (Fvertical_motion):
4003 * window.c (window_scroll_pixel_based, Frecenter):
4004 Don't pass `need_y_p' to `move_it_by_lines'.
4006 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
4008 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
4009 steal a few bits to be more compact.
4010 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
4011 Remove unneeded casts.
4013 * bytecode.c (Fbyte_code): CAR and CDR can GC.
4015 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
4017 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
4018 binding" message (bug#7967).
4020 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
4022 Fix more problems found by GCC 4.6.0's static checks.
4024 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
4025 Remove unused local var.
4027 * editfns.c (Fmessage_box): Remove unused local var.
4029 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
4030 (note_mode_line_or_margin_highlight, note_mouse_highlight):
4031 Omit unused local vars.
4032 * window.c (shrink_windows): Omit unused local var.
4033 * menu.c (digest_single_submenu): Omit unused local var.
4034 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
4035 Omit unused local var.
4037 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
4038 Don't assume string length fits in int.
4039 (keyremap_step, read_key_sequence): Use size_t for sizes.
4040 (read_key_sequence): Don't check last_real_key_start redundantly.
4042 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
4043 instead of alloca (Bug#8344).
4045 * eval.c (Fbacktrace): Don't assume nargs fits in int.
4046 (Fbacktrace_frame): Don't assume nframes fits in int.
4048 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
4050 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
4053 * term.c (produce_glyphless_glyph): Remove unnecessary test.
4055 * cm.c (calccost): Turn while-do into do-while, for clarity.
4057 * keyboard.c (syms_of_keyboard): Use the same style as later
4058 in this function when indexing through an array. This also
4059 works around GCC bug 48267.
4061 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
4063 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
4065 * chartab.c (sub_char_table_ref_and_range): Redo for slight
4066 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
4068 * keyboard.c, keyboard.h (num_input_events): Now size_t.
4069 This avoids undefined behavior on integer overflow, and is a bit
4070 more convenient anyway since it is compared to a size_t variable.
4072 Variadic C functions now count arguments with size_t, not int.
4073 This avoids an unnecessary limitation on 64-bit machines, which
4074 caused (substring ...) to crash on large vectors (Bug#8344).
4075 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
4076 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

4083 (funcall_lambda, mark_backtrace): Likewise.
4084 * fns.c (concat): Likewise.
4085 * frame.c (x_set_frame_parameters): Likewise.
4086 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
4087 0 if not found, not -1. All callers changed.
4089 * alloc.c (garbage_collect): Don't assume stack size fits in int.
4090 (stack_copy_size): Now size_t, not int.
4091 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
4093 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
4095 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
4096 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
4097 All callers changed.
4099 * lisp.h (multibyte_char_to_unibyte):
4100 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
4101 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
4102 * character.h (CHAR_TO_BYTE8):
4103 * cmds.c (internal_self_insert):
4104 * editfns.c (general_insert_function):
4105 * keymap.c (push_key_description):
4106 * search.c (Freplace_match):
4107 * xdisp.c (message_dolog, set_message_1): All callers changed.
4109 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

4112 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
4113 don't set the hook to nil, but remove the offending function instead.
4114 (Qcommand_hook_internal): Remove, unused.
4115 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
4116 Vcommand_hook_internal.
4118 * eval.c (enum run_hooks_condition): Remove.
4119 (funcall_nil, funcall_not): New functions.
4120 (run_hook_with_args): Call each function through a `funcall' argument.
4121 Remove `cond' argument, now redundant.

4130 * print.c (strout): Remove parameter `multibyte', unused since
4131 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
4133 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
4134 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
4135 All callers changed.
4137 * w32.c (_wsa_errlist): Use braces for struct initializers.
4139 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
4140 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
4141 All callers changed.
4142 (string_buffer_position): Likewise. Also, make static (it's never
4143 used outside xdisp.c).
4144 (cursor_row_p): Remove parameter `w', unused since
4145 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

4147 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
4148 All callers changed.
4150 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

4296 * buffer.c (Fkill_all_local_variables):
4297 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
4299 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
4300 unconditionnaly since it does the check itself.
4302 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
4304 Fix more problems found by GCC 4.5.2's static checks.
4306 * coding.c (encode_coding_raw_text): Avoid unnecessary test
4307 the first time through the loop, since we know p0 < p1 then.
4308 This also avoids a gcc -Wstrict-overflow warning.
4310 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
4311 leading to a memory leak, possible in functions like
4312 load_charset_map_from_file that can allocate an unbounded number
4313 of objects (Bug#8318).
4315 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
4316 that could (at least in theory) be that large.
4318 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
4319 This is less likely to overflow, and avoids undefined behavior if
4320 overflow does occur. All callers changed. Use strtoul to scan
4321 for the unsigned long integer.

4331 This also avoids a warning with gcc -Wstrict-overflow.
4333 * fileio.c (Fcopy_file): Report error if fchown or fchmod
4336 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
4338 * process.c (Fmake_network_process): Use socklen_t, not int,
4339 where POSIX says socklen_t is required in portable programs.
4340 This fixes a porting bug on hosts like 64-bit HP-UX, where
4341 socklen_t is wider than int (Bug#8277).
4342 (Fmake_network_process, server_accept_connection):
4343 (wait_reading_process_output, read_process_output):

4356 Make tparam.h and terminfo.c consistent.
4357 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
4358 Include tparam.h instead, since it declares them.
4359 * cm.h (PC): Remove extern decl; tparam.h now does this.
4360 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
4361 * terminfo.c: Include tparam.h, to check interfaces.
4362 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
4363 (tparam): Adjust signature to match interface in tparam.h;
4364 this removes some undefined behavior. Check that outstring and len
4365 are zero, which they always are with Emacs.
4366 * tparam.h (PC, BC, UP): New extern decls.
4368 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
4369 (xftfont_open): Rename locals to avoid shadowing.
4371 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

4389 with a FIXME (Bug#8290).
4391 character.h: Rename locals to avoid shadowing.

4410 (wav_play): Initialize a variable to 0, to prevent undefined
4411 behavior (Bug#8278).
4413 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
4415 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
4417 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
4418 clobbering (Bug#8298).
4419 * sysdep.c (sys_subshell): Likewise.
4420 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
4422 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
4423 This should get cleaned up, so that child_setup has the
4424 same signature on all platforms.
4426 * callproc.c (call_process_cleanup): Now static.
4427 (relocate_fd): Rename locals to avoid shadowing.
4429 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
4431 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
4432 not to be necessary, and produces flickering.
4434 2011-03-20 Glenn Morris <rgm@gnu.org>
4436 * config.in: Remove file.
4438 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

4483 Define only if needed.
4485 * unexelf.c (unexec): Name an expression,
4486 to avoid gcc -Wbad-function-cast warning.
4487 Use a different way to cause a compilation error if anyone uses
4488 n rather than nn, a way that does not involve shadowing.
4489 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
4491 * deps.mk (unexalpha.o): Remove; unused.
4493 New file unexec.h, the (simple) interface for unexec (Bug#8267).

4579 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
4580 Rename locals to avoid shadowing.

4591 avoids undefined behavior in theory.
4593 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
4595 Use functions, not macros, for up- and down-casing (Bug#8254).
4596 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4597 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
4598 to use the following functions instead of these macros.
4599 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
4600 EMACS_INT, since callers assume the returned value fits in int.

4615 (WORDCHAR_P): Likewise. This one is never needed, but is used

4617 the #if 0 of that comment.
4618 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):

4655 Rename locals to avoid shadowing.
4657 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
4658 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in

4661 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
4662 * buffer.h: ... to here, because these macros use current_buffer,

4666 (downcase, upcase1): New static inline functions.
4667 (DOWNCASE, UPCASE1): Reimplement using these functions.

4709 * buffer.c (fix_overlays_before): Mark locals as initialized.
4710 (fix_start_end_in_overlays): Likewise. This function should be

4721 (MAXPATHLEN): Define only if needed.
4723 * process.c (serial_open, serial_configure): Move decls from here ...
4724 * systty.h: ... to here, so that they can be checked.

5084 (detect_coding_iso_2022): Initialize a local variable that might
5085 be used uninitialized. Leave a FIXME because it's not clear that
5086 this initialization is needed. (Bug#8211)
5087 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
5088 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):
5089 (SHIFT_OUT_OK, ENCODE_CONTROL_SEQUENCE_INTRODUCER):
5090 (ENCODE_DIRECTION_R2L, ENCODE_DIRECTION_L2R):
5091 Remove unused macros.
5093 * category.c (hash_get_category_set): Remove unused local var.
5094 (copy_category_table): Now static, since it's not used elsewhere.
5095 * character.c (string_count_byte8): Likewise.
5097 * ccl.c (CCL_WRITE_STRING, CCL_ENCODE_CHAR, Fccl_execute_on_string):
5098 (Fregister_code_conversion_map): Rename locals to avoid shadowing.

5119 Move these decls to tparam.h, and make them agree with what
5120 is actually in tparam.c. The previous trick of using incompatible
5121 decls in different modules does not conform to the C standard.
5122 All callers of tparam changed to use tparam's actual API.
5123 * tparam.c (tparam1, tparam, tgoto):
5124 Use const pointers where appropriate.

5132 (turn_on_face, init_tty): Likewise.
5133 * termchar.h (struct tty_display_info): Likewise.
5135 * term.c (term_mouse_position): Rename local to avoid shadowing.
5137 * alloc.c (mark_ttys): Move decl from here ...
5138 * lisp.h (mark_ttys): ... to here, so that it's checked against defn.
