1 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
2
3 Fix race conditions involving setenv, gmtime, localtime, asctime.
4 Without this fix, interrupts could mess up code that uses these
5 nonreentrant functions, since setting TZ invalidates existing
6 tm_zone or tzname values, and since most of these functions return
7 pointers to static storage.
8 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
10 Grow the critical sections to include not just invoking
11 localtime/gmtime, but also accessing these functions' results
12 including their tm_zone values if any, and any related TZ setting.
13 (format_time_string): Last arg is now struct tm *, not struct tm **,
14 so that the struct tm is saved in the critical section. All
15 callers changed. Simplify allocation of initial buffer, partly
16 motivated by the fact that memory allocation needs to be outside
17 the critical section.
18
19 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
20
21 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
22 with RESET_INTERVAL.
23
24 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
25 Remove duplicated buffer name initialization.
26
27 2012-05-02 Jim Meyering <jim@meyering.net>
28
29 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).

31 * xfns.c (x_window): Use xstrdup (Bug#11375).
32
33 2012-05-02 Eli Zaretskii <eliz@gnu.org>
34
35 * xdisp.c (pos_visible_p): If already at a newline from the
36 display string before the 'while' loop, don't walk back the glyphs
37 from it3.glyph_row. Solves assertion violation when the display
38 string begins with a newline (egg.el). (Bug#11367)
39
40 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
41
42 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):

48 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
49 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
50 All were removed before 23.1.
51
52 * dispnew.c: Remove HAVE_LIBNCURSES test;
53 it is always true on relevant platforms.
54
55 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
56 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
57

65
66 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
67
68 Do not avoid creating empty evaporating overlays (Bug#9642).
69 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
70 That is, do not delete an evaporating overlay if it becomes
71 empty after its bounds are adjusted to fit within its buffer.
72 This fix caused other problems, and I'm reverting it until we get
73 to the bottom of them.
74
75 2012-04-27 Chong Yidong <cyd@gnu.org>
76
77 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).

80
81 * xdisp.c (pos_visible_p): If the window start position is beyond
82 ZV, start the display from buffer beginning. Prevents assertion
83 violation in init_iterator when the minibuffer window is scrolled
84 via the scroll bar.
85
86 * window.c (window_scroll_pixel_based): Likewise.
87
88 2012-04-27 Chong Yidong <cyd@gnu.org>
89
90 * keymap.c (where_is_internal): Doc fix (Bug#10872).
91
92 2012-04-27 Glenn Morris <rgm@gnu.org>
93
94 * fileio.c (Fcopy_file, Fset_file_selinux_context):
95 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
96
97 2012-04-27 Eli Zaretskii <eliz@gnu.org>
98
99 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
100 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
101
102 2012-04-26 Eli Zaretskii <eliz@gnu.org>
103
104 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
105 display element, check also the underlying string or buffer
106 character. (Bug#11341)
107
108 * w32menu.c: Include w32heap.h.
109 (add_menu_item): If the call to AppendMenuW (via
110 unicode_append_menu) fails, disable Unicode menus only if we are
111 running on Windows 9X/Me.
112
113 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
114
115 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
116 (xgetint): Add missing shift for LSB tags.
117
118 2012-04-24 Martin Rudalics <rudalics@gmx.at>
119
120 * keyboard.c (read_char): Don't wipe echo area for select window
121 events: These might get delayed via `mouse-autoselect-window'
122 (Bug#11304).
123
124 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
125

128
129 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
130
131 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
132 now a cons (bug#11311).
133
134 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
135
136 Do not create empty overlays with the evaporate property (Bug#9642).
137 * buffer.c (Fmove_overlay): Delete an evaporating overlay
138 if it becomes empty after its bounds are adjusted to fit within
139 its buffer. Without this fix, in a nonempty buffer (let ((o
140 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
141 yields an empty overlay that has the evaporate property, which is
142 not supposed to happen.
143

165 * gmalloc.c: (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
166 (__malloc_size_t, __malloc_ptrdiff_t):

178 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
179 Define using prototypes, not old style.
180 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):

264 2012-04-21 Eduard Wiebe <usenet@pusto.de>
265
266 * sysdep.c (list_system_processes, system_process_attributes):

440 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
441
442 * w32.c (w32_delayed_load): Record the full path of the library
443 being loaded (bug#10424).
444
445 2012-04-09 Glenn Morris <rgm@gnu.org>
446
447 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
448 not just in the obarray, before snarfing them. (Bug#11036)
449
450 * Makefile.in ($(leimdir)/leim-list.el):
451 Pass EMACS rather than BUILT_EMACS.
452
453 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
454
455 * process.c (make_process):
456 * process.h: Add integer `gnutls_handshakes_tried' member to
457 process struct.

461
462 * gnutls.c (gnutls_log_function2i): Convenience log function.
463 (emacs_gnutls_read): Use new log functions,
464 `gnutls_handshakes_tried' process member, and
465 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
466 attempts per process (connection).
467
468 2012-04-09 Chong Yidong <cyd@gnu.org>
469
470 * eval.c (Fuser_variable_p, user_variable_p_eh)
471 (lisp_indirect_variable): Functions deleted.

476
477 2012-04-09 Eli Zaretskii <eliz@gnu.org>
478
479 * xdisp.c (set_cursor_from_row): If the display string appears in
480 the buffer at position that is closer to point than the position
481 after the display string, display the cursor on the first glyph of
482 the display string. Fixes cursor display when a 'display' text
483 property immediately follows invisible text. (Bug#11094)
484
485 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
486
487 composite.c: use 'double' consistently
488 * composite.c (get_composition_id): Use 'double' consistently
489 instead of converting 'float' to 'double' and vice versa; this is
490 easier to understand and avoids a GCC warning.
491
492 2012-04-09 Glenn Morris <rgm@gnu.org>
493
494 * Makefile.in: Generate leim-list with bootstrap-emacs, in
495 preparation for dumping it with emacs. (Bug#4789)
496 (leimdir): New variable.
497 ($(leimdir)/leim-list.el): New rule.
498 (emacs$(EXEEXT)): Depend on leim-list.el.
499

512 Remove unused local variable.
513
514 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
515
516 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
517 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
518 (mark_memory): Mark Lisp_Objects only if pointers might hide in
519 objects, as mark_maybe_pointer will catch them otherwise.
520 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
521 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
522
523 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
524
525 Fix typo that broke non-Windows builds.
526 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

538 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
539 [!WINDOWSNT]: New macros.
540 (init_libxml2_functions, libxml2_loaded_p): New functions.
541 (parse_region): Call fn_xmlCheckVersion instead of using the macro
542 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
543 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
544 Calls xmlCleanupParser only if libxml2 was loaded (or statically
545 linked in).
546 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
547 Call init_libxml2_functions before calling libxml2 functions.
548 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
549
550 * emacs.c: Don't include libxml/parser.h.
551 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
552 xmlCleanupParser directly.
553
554 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
555
556 2012-04-07 Eli Zaretskii <eliz@gnu.org>
557
558 * indent.c (Fvertical_motion): If there is a display string at
559 point, use it.vpos to compute how many lines to backtrack after
560 move_it_to point. (Bug#11133)
561
562 2012-04-06 Eli Zaretskii <eliz@gnu.org>
563
564 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
565 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
566 about subtle differences between FETCH_CHAR* and STRING_CHAR*
567 macros related to unification of CJK characters. For the details,
568 see the discussion following the message here:
569 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
570
571 2012-04-04 Chong Yidong <cyd@gnu.org>

574
575 2012-04-01 Eli Zaretskii <eliz@gnu.org>
576

578 instead of alloca. (Bug#11138)
579
580 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
581
582 * w32menu.c (is_simple_dialog): Properly check lisp types.
583 (Bug#11141)
584
585 2012-03-31 Eli Zaretskii <eliz@gnu.org>
586
587 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
588 position we get to after a call to move_it_to fails the
589 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
590 only if we wind up in a string from display property. (Bug#11063)
591
592 * window.c (Fdelete_other_windows_internal): Invalidate the row
593 and column information about mouse highlight, so that redisplay
594 restores it after reallocating the glyph matrices. (Bug#7464)
595
596 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
597 string comes from a `display' text property, use the buffer
598 position of that property as if we actually saw that position in
599 the row's glyphs.
600 (move_it_by_lines): Remove the assertion that
601 "it->current_x == 0 && it->hpos == 0" which can be legitimately
602 violated when there's a before-string at the beginning of a line.
603 (Bug#11063)
604
605 2012-03-30 Eli Zaretskii <eliz@gnu.org>
606
607 * xdisp.c (append_space_for_newline): If the default face was
608 remapped, use the remapped face for the appended newline.
609 (extend_face_to_end_of_line): Use the remapped default face for
610 extending the face to the end of the line.
611 (display_line): Call extend_face_to_end_of_line when the default
612 face was remapped. (Bug#11068)
613
614 2012-03-29 Eli Zaretskii <eliz@gnu.org>
615
616 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
617
618 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
619

621
622 2012-03-27 Glenn Morris <rgm@gnu.org>
623
624 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
625 Doc fixes.
626
627 2012-03-26 Kenichi Handa <handa@m17n.org>
628
629 * dispextern.h (struct glyph): Fix previous change. Change the
630 bit length of glyphless.ch to 25 (Bug#11082).
631
632 2012-03-26 Chong Yidong <cyd@gnu.org>
633
634 * keyboard.c (Vselection_inhibit_update_commands): New variable.
635 (command_loop_1): Use it; inhibit selection update for
636 handle-select-window too (Bug#8996).
637
638 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
639
640 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
641
642 2012-03-25 Kenichi Handa <handa@m17n.org>
643
644 * dispextern.h (struct glyph): Change the bit length of
645 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
646
647 2012-03-24 Eli Zaretskii <eliz@gnu.org>
648
649 * s/ms-w32.h (tzname): Include time.h before redirecting to
650 _tzname. Fixes the MSVC build. (Bug#9960)
651
652 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
653
654 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
655 characters.
656
657 * xterm.c (XTread_socket): Only modify handling_signal if
658 !SYNC_INPUT. (Bug#11080)
659
660 2012-03-23 Eli Zaretskii <eliz@gnu.org>
661
662 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
663 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
664 when fetching a multibyte character consumes more bytes than
665 CHAR_BYTES returns, due to unification of CJK characters in
666 string_char. (Bug#11073)
667
668 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
669
670 * process.c (wait_reading_process_output): Handle pty disconnect
671 by refraining from sending oneself a SIGCHLD (bug#10933).
672
673 2012-03-22 Chong Yidong <cyd@gnu.org>
674
675 * dispextern.h (struct it): New member string_from_prefix_prop_p.
676
677 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
678 Mark string as coming from a prefix property.
679 (handle_face_prop): Use default face for prefix strings (Bug#4281).
680 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
681
682 2012-03-21 Chong Yidong <cyd@gnu.org>
683
684 * xfaces.c (Vface_remapping_alist): Doc fix.
685
686 2012-03-20 Eli Zaretskii <eliz@gnu.org>
687
688 * w32proc.c (Fw32_set_console_codepage)
689 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
690 Doc fixes.

692 2012-03-20 Chong Yidong <cyd@gnu.org>
693
694 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
695 to reflect default non-nil value of redisplay-dont-pause.
696
697 2012-03-19 Kenichi Handa <handa@m17n.org>
698
699 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
700 it fit in a valid range (Bug#11003).
701
702 2012-03-18 Eli Zaretskii <eliz@gnu.org>
703
704 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
705 that is not from display property, accept the row as a "cursor
706 row" if one of the string's character has a non-nil `cursor'
707 property. Fixes cursor positioning when there are newlines in
708 overlay strings, e.g. in icomplete.el. (Bug#11035)
709
710 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
711
712 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
713
714 2012-03-12 Chong Yidong <cyd@gnu.org>
715
716 * eval.c (inhibit_lisp_code): Rename from
717 inhibit_window_configuration_change_hook; move from window.c.
718
719 * xfns.c (unwind_create_frame_1, Fx_create_frame):
720 * window.c (run_window_configuration_change_hook)
721 (syms_of_window): Callers changed.
722
723 2012-03-11 Chong Yidong <cyd@gnu.org>
724
725 * keymap.c (Fkey_description): Doc fix (Bug#9700).
726
727 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
728
729 2012-03-10 Chong Yidong <cyd@gnu.org>
730
731 * frame.c (other_visible_frames): Don't assume the selected frame
732 is visible (Bug#10955).
733
734 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
735
736 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
737
738 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
739
740 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
741 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
742 zero (Bug#10954).
743
744 2012-03-03 Glenn Morris <rgm@gnu.org>
745
746 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
747
748 2012-03-02 Eli Zaretskii <eliz@gnu.org>
749
750 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
751 position past the first glyph_row that ends at ZV. (Bug#10902)
752 (redisplay_window, next_element_from_string): Fix typos in
753 comments.
754 (redisplay_window): Pass to move_it_vertically the margin in
755 pixels, not in screen lines.
756
757 2012-03-02 Glenn Morris <rgm@gnu.org>
758
759 * buffer.c (buffer-list-update-hook): Doc fix.
760
761 2012-02-29 Eli Zaretskii <eliz@gnu.org>
762
763 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
764 push_it before setting up the iterator for the first overlay
765 string, even if we have an empty string loaded.
766 (next_overlay_string): If there's an empty string on the iterator
767 stack, pop the stack. (Bug#10903)
768
769 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
770
771 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
772 Suggested by Stefan Monnier in
773 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
774 * alloc.c (widen_to_Lisp_Object): New static function.
775 (mark_memory): Also mark Lisp_Objects by fetching pointer words
776 and widening them to Lisp_Objects. This would work even if
777 USE_LSB_TAG is defined and wide integers are used, which might
778 happen in a future version of Emacs.
779
780 2012-02-25 Chong Yidong <cyd@gnu.org>
781
782 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
783 Doc fix.
784
785 * xselect.c (Fx_selection_exists_p): Doc fix.

787 before saving to clipboard manager.
788
789 2012-02-24 Chong Yidong <cyd@gnu.org>
790
791 * keyboard.c (process_special_events): Handle all X selection
792 requests in kbd_buffer, not just the next one (Bug#8869).
793
794 2012-02-23 Chong Yidong <cyd@gnu.org>
795
796 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
797 call when setting menu-bar-lines and tool-bar-lines parameters.
798 (unwind_create_frame_1): New helper function.
799
800 * window.c (inhibit_window_configuration_change_hook): New var.
801 (run_window_configuration_change_hook): Obey it.
802 (syms_of_window): Initialize it.
803
804 2012-02-22 Chong Yidong <cyd@gnu.org>
805
806 * xterm.c (x_draw_image_relief): Add missing type check for
807 Vtool_bar_button_margin (Bug#10743).
808
809 2012-02-21 Chong Yidong <cyd@gnu.org>
810
811 * fileio.c (Vfile_name_handler_alist): Doc fix.
812
813 * buffer.c (Fget_file_buffer): Protect against invalid file
814 handler return value.
815
816 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
817
818 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
819 when computing $valmask.
820
821 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
822 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
823 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
824 It's useless in that case, and it can cause problems on hosts
825 that allocate halves of EMACS_INT values separately.
826 Reported by Dan Horák. Diagnosed by Andreas Schwab in
827 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
828 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
829 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
830 it avoids undefined behavior on hosts where shifting right by more
831 than the word width has undefined behavior.
832
833 2012-02-19 Chong Yidong <cyd@gnu.org>
834
835 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)

839 return values (Bug#10845).
840
841 2012-02-18 Eli Zaretskii <eliz@gnu.org>
842
843 * .gdbinit (pitx): Fix incorrect references to fields of the
844 iterator stack.
845
846 2012-02-17 Chong Yidong <cyd@gnu.org>
847

849
850 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
851
852 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
853 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
854
855 2012-02-15 Chong Yidong <cyd@gnu.org>
856
857 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
858 marked as special. Also, starting docstrings with * is obsolete.
859

861
862 * gnutls.c (emacs_gnutls_write): Fix last change.

865
866 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
867 send_process.
868
869 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
870
871 * keymap.c (Fsingle_key_description): Handle char ranges.
872
873 2012-02-12 Chong Yidong <cyd@gnu.org>
874
875 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
876 as that creates a dangerous corner case.
877
878 * window.c (Fdelete_window_internal): Invalidate the mouse
879 highlight (Bug#9904).
880
881 2012-02-12 Glenn Morris <rgm@gnu.org>

1461
1462 2011-11-29 Jan Djärv <jan.h.d@swipnet.se>

1611 Otherwise, valgrind does not work on some platforms.
1612 Problem reported by Andreas Schwab in
1613 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
1614 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
1615 is set, removing the need for VIRT_ADDRESS_VARIES.
1616 (PURE_P): Use a more-efficient implementation that needs just one
1617 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
1618 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
1619 to 4 (xorl, subq, cmpq, setbe).
1620 * alloc.c (pure): Always extern now, since that's the
1621 VIRT_ADDR_VARIES behavior.
1622 (PURE_POINTER_P): Use a single comparison, not two, for
1623 consistency with the new puresize.h.
1624 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

1631 (erase_phys_cursor, update_window_cursor, show_mouse_face)
1632 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
1633 behave as if the cursor position were at the window margin.
1634
1635 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
1636 and the cursor position is out of bounds, behave as if the cursor
1637 position were at the window margin. (Bug#10075)
1638
1639 2011-11-18 Chong Yidong <cyd@gnu.org>
1640
1641 * window.c (Fwindow_combination_limit): Make first argument
1642 non-optional, since it is meaningless for live windows like the
1643 selected window.

1657 hash values of the two rows.
1658 (copy_row_except_pointers): Preserve the used[] arrays and the
1659 hash values of the two rows. (Bug#10035)
1660 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
1661
1662 * xdisp.c (row_hash): New function, body extracted from
1663 compute_line_metrics.
1664 (compute_line_metrics): Call row_hash, instead of computing the
1665 hash code inline.
1666
1667 * dispnew.c (verify_row_hash): Call row_hash for computing the
1668 hash code of a row, instead of duplicating code from xdisp.c.
1669
1670 * dispextern.h (row_hash): Add prototype.
1671
1672 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

1689
1690 * nsfns.m (Fns_font_name):

1708 2011-11-14 Eli Zaretskii <eliz@gnu.org>
1709
1710 * xdisp.c (display_line): Move the call to
1711 highlight_trailing_whitespace before the call to
1712 compute_line_metrics, since the latter needs to see the final
1713 faces of all the glyphs to compute ROW's hash value.
1714 Fixes assertion violations in row_equal_p. (Bug#10035)
1715
1716 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
1717
1718 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
1719 just return (bug#10044).
1720
1721 2011-11-12 Eli Zaretskii <eliz@gnu.org>
1722
1723 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
1724 with user-defined heap size. Bump the default size of the temacs
1725 heap to 27MB, to avoid memory warning when running temacs.
1726 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
1727
1728 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

1857 Otherwise, these inline functions do not conform to C99 and
1858 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in

2149
2150 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
2151
2152 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
2153
2154 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
2155
2156 * keyboard.c (test_undefined): New function (bug#9751).
2157 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
2158
2159 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
2160
2161 * sysdep.c (init_sys_modes): Fix the check for the controlling
2162 terminal (Bug#6649).
2163
2164 2011-10-20 Eli Zaretskii <eliz@gnu.org>
2165
2166 * dispextern.h (struct bidi_it): New member next_en_type.
2167
2168 * bidi.c (bidi_line_init): Initialize the next_en_type member.
2169 (bidi_resolve_explicit_1): When next_en_pos is valid for the
2170 current character, check also for next_en_type being WEAK_EN.
2171 (bidi_resolve_weak): Don't enter the expensive loop if the current
2172 position is before next_en_pos. Record the bidi type of the first
2173 non-ET, non-BN character we find, in addition to its position.
2174 (bidi_level_of_next_char): Invalidate next_en_type when
2175 next_en_pos is over-stepped.
2176

2178
2179 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
2180 * editfns.c: Rewrite current-time-zone so that it invokes
2181 the equivalent of (format-time-string "%Z") to get the time zone name.
2182 This fixes a bug when the time zone name contains characters that
2183 need converting from the system time locale to Emacs internal format.
2184 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
2185 that patch fixed format-time-string to do the conversion, but
2186 I forgot to fix current-time-zone.
2187 (format_time_string): New function, containing most of
2188 what Fformat_time_string used to contain.
2189 (Fformat_time_string): Rewrite in terms of format_time_string.
2190 This doesn't change this function's behavior.
2191 (current-time-zone): Rewrite to use format_time_string.
2192 This fixes the bug reported by Michael Schierl in
2193 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
2194 Jason Rumney's 2007-06-07 change worked around this bug, but
2195 didn't fix it.
2196 * systime.h (tzname, timezone): Remove no-longer-used declarations.
2197
2198 2011-10-19 Eli Zaretskii <eliz@gnu.org>
2199
2200 * xdisp.c (start_display): If the character at POS is displayed
2201 via a display vector, reset IT->current.dpvec_index to zero.
2202 (try_window_reusing_current_matrix): If a line ends in a display
2203 vector or the next line starts in a display vector, continue
2204 redrawing the window even though the character position of
2205 start_row was reached.
2206 (Bug#9771, part 2)
2207
2208 2011-10-18 Chong Yidong <cyd@gnu.org>
2209
2210 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
2211 with nobreak-char-display too.
2212
2213 2011-10-18 Eli Zaretskii <eliz@gnu.org>
2214
2215 Fix part 3 of bug#9771.
2216 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
2217 (bidi_resolve_neutral): Don't enter the expensive loop looking for
2218 non-neutral characters if the current character is a paragraph
2219 separator (a.k.a. Newline). This avoids running the same
2220 expensive loop twice, once when we consume the preceding newline
2221 and the other time when the line actually needs to be displayed.
2222 Avoid the loop when we see neutrals on the base embedding level
2223 following a character whose directionality is the same as the
2224 paragraph's. This avoids running the expensive loop when a line
2225 ends in a long sequence of neutrals, like control characters.
2226 Add assertion against STRONG_AL type. Slightly rearrange code
2227 that determines the type of a neutral given the first non-neutral
2228 that follows it.
2229 (bidi_level_of_next_char): Set next_en_pos to zero when
2230 invalidating its info.
2231
2232 2011-10-17 Eli Zaretskii <eliz@gnu.org>
2233
2234 * xdisp.c (push_display_prop): Determine whether to record string
2235 or buffer position by IT->string, not by IT->method. Allow
2236 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
2237 (move_it_vertically_backward): Don't look for character position
2238 immediately after the newline when in a continuation line.
2239 (Bug#9771, part 1)
2240
2241 2011-10-15 Martin Rudalics <rudalics@gmx.at>

2244 vertical border check. (Bug#5357) (Bug#9618)
2245
2246 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
2247
2248 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
2249 errors in XSetWindowBorder (bug#9310).
2250
2251 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
2252
2253 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
2254 avoid crash when xmalloc overrun checking is enabled.
2255
2256 2011-10-13 Eli Zaretskii <eliz@gnu.org>
2257
2258 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
2259 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
2260 cursor motion with <left> and <right> arrow keys.
2261
2262 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
2263 some callers set that themselves.
2264
2265 2011-10-12 Eli Zaretskii <eliz@gnu.org>
2266
2267 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
2268 display string and the previous row comes from the same string and
2269 is empty. (Bug#9739) (Bug#9738)
2270
2271 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
2272
2273 * doc.c (get_doc_string): Encode file name (bug#9735).
2274
2275 2011-10-12 Eli Zaretskii <eliz@gnu.org>
2276
2277 * bidi.c (bidi_level_of_next_char):
2278 * xdisp.c (get_visually_first_element): Remove old incorrect
2279 comments regarding the Unicode Line Separator character.
2280
2281 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
2282
2283 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
2284
2285 * alloc.c (Fgc_status): Do not access beyond zombies array
2286 boundary if nzombies > MAX_ZOMBIES.
2287 * alloc.c (dump_zombies): Add missing format specifier.
2288
2289 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
2290
2291 * xdisp.c (set_cursor_from_row): Simplify conditionals,
2292 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
2293
2294 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
2295 Some packages use them to denote characters with modifiers.
2296
2297 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
2298
2299 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
2300 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
2301 matching a pp-number. Rename parameter var to var1.
2302
2303 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
2304
2305 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
2306
2307 2011-10-08 Glenn Morris <rgm@gnu.org>
2308
2309 * callint.c (Fcall_interactively): Give a more explicit error for the
2310 'c' case with a non-character input. (Bug#8479)
2311
2312 2011-10-08 Eli Zaretskii <eliz@gnu.org>
2313
2314 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
2315 lines.
2316 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
2317 lines that are hscrolled on the left.
2318
2319 * dispnew.c (buffer_posn_from_coords): Account for a possible
2320 presence of header-line. (Bug#4426)
2321
2322 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
2323
2324 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
2325 Don't advertise functionality which we discourage or doesn't work.
2326
2327 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
2328
2329 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
2330 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
2331 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
2332 this makes Emacs dump core during garbage collection on rare
2333 occasions. sizeof is obviously inferior to offsetof here, so
2334 stick with offsetof.
2335 (GC_POINTER_ALIGNMENT): New macro.
2336 (mark_memory): Omit 3rd (offset) arg; caller changed.
2337 Don't assume EMACS_INT alignment is the same as pointer alignment.
2338
2339 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
2340
2341 * keyboard.c (read_key_sequence_remapped): New var.
2342 (read_key_sequence): Compute remapping in the right buffer.
2343 (command_loop_1): Use read_key_sequence's remapping directly.
2344
2345 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2346
2347 * dired.c (file_name_completion): Don't expand file name.
2348 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
2349 before checking file name handler.
2350
2351 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
2352 they've been requested explicitly (bug#9591).
2353
2354 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
2355
2356 * keymap.c (Fsingle_key_description): Use make_specified_string
2357 instead of build_string to build string from push_key_description.
2358 (Bug#5193)
2359
2360 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
2361
2362 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
2363 This fixes a Y2038 bug on 64-bit hosts.
2364 * buffer.c (reset_buffer):
2365 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
2366 (Fclear_buffer_auto_save_failure):
2367 Use 0, not -1, to represent an unset failure time, since time_t
2368 might not be signed.
2369
2370 Remove dependency on glibc malloc internals.
2371 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
2372 Move back here from lisp.h, but with their new implementations.
2373 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
2374 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
2375 * charset.c (charset_table_init): New static var.
2376 (syms_of_charset): Use it instead of xmalloc. This removes a
2377 dependency on glibc malloc internals. See Eli Zaretskii's comment in
2378 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
2379 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
2380 Move back to alloc.c.
2381 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
2382 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
2383
2384 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
2385
2386 * nsterm.m (windowDidResize): Call x_set_window_size only when
2387 ns_in_resize is true. Otherwise set pixelwidth/height and
2388 call change_frame_size (Bug#9628).
2389
2390 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
2391
2392 Port --enable-checking=all to Fedora 14 x86-64.
2393 * charset.c (syms_of_charset): Also account for glibc malloc's
2394 internal overhead when calculating the initial malloc maximum.
2395
2396 Port --enable-checking=all to Fedora 14 x86.
2397 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
2398 Move to lisp.h.
2399 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
2400 (overrun_check_realloc, overrun_check_free):
2401 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
2402 That way, xmalloc returns a properly-aligned pointer even if
2403 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
2404 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
2405 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
2406 into account when calculating the initial malloc maximum.
2407 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
2408 Move here from alloc.c, so that charset.c can use it too.
2409 Properly align; the old code wasn't right for common 32-bit hosts
2410 when configured with --enable-checking=all.
2411 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
2412 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
2413
2414 2011-09-29 Eli Zaretskii <eliz@gnu.org>
2415
2416 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
2417 use EDOM.
2418
2419 2011-09-28 Eli Zaretskii <eliz@gnu.org>
2420
2421 * xdisp.c (compute_display_string_end): If there's no display
2422 string at CHARPOS, return -1.
2423
2424 * bidi.c (bidi_fetch_char): When compute_display_string_end
2425 returns a negative value, treat the character as a normal
2426 character not covered by a display string. (Bug#9624)
2427
2428 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
2429
2430 * lread.c (Fread_from_string): Fix typo in docstring.
2431
2432 2011-09-27 Eli Zaretskii <eliz@gnu.org>
2433
2434 * xdisp.c (handle_invisible_prop): If invisible text ends on a
2435 newline, reseat the iterator instead of bidi-iterating there one
2436 character at a time. (Bug#9610)
2437 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
2438 TO_CHARPOS if the bidi iterator is at base embedding level.
2439
2440 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
2441
2442 * lread.c (readevalloop): Use correct code for NBSP.
2443 (read1): Likewise. (Bug#9608)
2444
2445 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
2446
2447 * dbusbind.c (Fdbus_register_signal): When service is not
2448 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
2449
2450 2011-09-25 Glenn Morris <rgm@gnu.org>

2458
2459 2011-09-24 Glenn Morris <rgm@gnu.org>
2460
2461 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
2462
2463 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
2464
2465 Fix minor problems found by static checking.
2466 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
2467 * indent.c (Fvertical_motion): Fix == vs = typo.
2468
2469 2011-09-24 Eli Zaretskii <eliz@gnu.org>
2470
2471 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
2472 Default value is now t. Doc fix.
2473
2474 * indent.c (Fvertical_motion): Compute and apply the overshoot
2475 logic when moving up, not only when moving down. Fix the
2476 confusing name and values of the it_overshoot_expected variable;
2477 logic changes accordingly. (Bug#9254) (Bug#9549)
2478
2479 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
2480 CHARPOS is covered by a display string which includes newlines.
2481 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
2482 is covered by a display string with embedded newlines.
2483
2484 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
2485
2486 * dbusbind.c (Fdbus_register_signal): Add match rule to
2487 Vdbus_registered_objects_table. (Bug#9581)
2488 (Fdbus_register_method, Vdbus_registered_objects_table):
2489 Fix docstring.
2490
2491 2011-09-24 Jim Meyering <meyering@redhat.com>
2492
2493 do not ignore write error for any output size
2494 The previous change was incomplete.
2495 While it makes emacs --batch detect the vast majority of stdout
2496 write failures, errors were still ignored whenever the output size is
2497 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
2498 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
2499 && echo FAIL: ignored write error
2500 FAIL: ignored write error
2501 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
2502 && echo FAIL: ignored write error
2503 FAIL: ignored write error
2504 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
2505
2506 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
2507
2508 * emacs.c (Fkill_emacs): In noninteractive mode exit
2509 non-successfully if a write error occurred on stdout. (Bug#9574)
2510
2511 2011-09-21 Eli Zaretskii <eliz@gnu.org>
2512
2513 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
2514 the xassert test.
2515
2516 * dispextern.h (struct it): Update the comment documenting what
2517 can it->OBJECT be.
2518
2519 2011-09-20 Eli Zaretskii <eliz@gnu.org>
2520
2521 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
2522 a display string, extend search for cursor position to end of row.
2523 (find_row_edges): If the row ends in a newline from a display
2524 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
2525 Handle the case of a display string with multiple newlines.
2526 (Fcurrent_bidi_paragraph_direction): Fix search for previous
2527 non-empty line. Fixes confusing cursor motion with arrow keys at
2528 the beginning of a line that starts with whitespace.
2529
2530 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
2531

2539
2540 2011-09-18 Eli Zaretskii <eliz@gnu.org>
2541
2542 * xdisp.c (display_line): Record maximum and minimum buffer
2543 positions even if no glyphs were produced (e.g., by a zero-width
2544 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
2545 buffer positions that will be removed from the glyph row because
2546 they don't fit.
2547 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
2548 column is beyond frame width: don't subtract 1 "pixel" when
2549 computing width of the stretch.
2550 (reseat_at_next_visible_line_start): Undo the change made on
2551 2011-09-17 that saved paragraph information and restored it after
2552 the call to `reseat'. (Bug#9545)
2553
2554 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

2561 * search.c (boyer_moore): Take unibyte characters from pattern
2562 literally. (Bug#9458)
2563
2564 2011-09-18 Eli Zaretskii <eliz@gnu.org>
2565
2566 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.

2568 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
2569
2570 Fix minor problem found by static checking.
2571 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
2572 initialized, to pacify gcc -Wuninitialized.
2573
2574 * fileio.c: Report proper errno when syscall falls.
2575 (Finsert_file_contents): Save and restore errno,
2576 so that report_file_error outputs the correct diagnostic.
2577 (Fwrite_region) [CLASH_DETECTION]: Likewise.
2578
2579 2011-09-18 Eli Zaretskii <eliz@gnu.org>

2582
2583 2011-09-17 Eli Zaretskii <eliz@gnu.org>
2584
2585 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
2586 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
2587
2588 2011-09-17 Eli Zaretskii <eliz@gnu.org>
2589
2590 * xdisp.c (reseat_at_next_visible_line_start): Keep information
2591 about the current paragraph and restore it after the call to reseat.
2592
2593 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
2594 (bidi_find_paragraph_start): Search back for paragraph beginning
2595 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
2596 (bidi_move_to_visually_next): Only trigger paragraph-related
2597 computations when the last character is a newline or at EOB, not
2598 just any NEUTRAL_B. (Bug#9470)
2599
2600 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
2601 truncated lines if point is covered by a display string. (Bug#9524)
2602
2603 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
2604
2605 * xselect.c: Relax test for outgoing X longs (Bug#9498).
2606 (cons_to_x_long): New function.
2607 (lisp_data_to_selection_data): Use it. Correct the test for
2608 short-versus-long data; it was negated. Break out of vector
2609 loop, for efficiency, when a long datum is discovered.
2610
2611 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
2612
2613 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
2614
2615 2011-09-16 Eli Zaretskii <eliz@gnu.org>
2616
2617 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
2618 GCC PR/17406) by declaring this function with external scope.
2619
2620 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
2621
2622 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
2623 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
2624
2625 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
2626
2627 * editfns.c (Fformat): Correctly handle text properties on "%%".

2634 * composite.c (composition_update_it, get_composition_id):
2635 * xdisp.c (get_next_display_element)
2636 (fill_composite_glyph_string): Add comments about special meaning
2637 of TAB characters in a composition.
2638
2639 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
2640
2641 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
2642 This occurs when processing a multibyte format.
2643 Problem reported by Wolfgang Jenker.
2644
2645 2011-09-15 Johan Bockgård <bojohan@gnu.org>
2646
2647 * xdisp.c (try_cursor_movement): Only check for exact match if
2648 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
2649
2650 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
2651
2652 Remove unused external symbols.
2653 * dispextern.h (calc_pixel_width_or_height): Remove decl.
2654 * xdisp.c (calc_pixel_width_or_height): Now static.
2655 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
2656 * indent.c (check_display_width):
2657 * w32term.c: Fix comment to match code.
2658 * xterm.c, xterm.h (x_catching_errors): Remove.
2659
2660 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
2661
2662 * xselect.c: Use signed conversions more consistently (Bug#9498).
2663 (selection_data_to_lisp_data): Assume incoming selection data are
2664 signed integers, not unsigned. This is to be consistent with
2665 outgoing selection data, which was modified to use signed integers
2666 in as part of the fix to Bug#9196 in response to Jan D.'s comment
2667 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
2668 expects long, not unsigned long.
2669
2670 2011-09-14 Eli Zaretskii <eliz@gnu.org>
2671
2672 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
2673 computation of loop end. Reported by Johan Bockgård
2674 <bojohan@gnu.org>.
2675
2676 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
2677
2678 * frame.c (Fother_visible_frames_p): Function deleted.
2679
2680 2011-09-12 Eli Zaretskii <eliz@gnu.org>
2681
2682 * indent.c (compute_motion): Process display vector front to back
2683 rather than the other way around. (Bug#2496)
2684
2685 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2686
2687 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
2688
2689 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
2690
2691 * minibuf.c (Fread_from_minibuffer): Doc fix.
2692
2693 2011-09-11 Eli Zaretskii <eliz@gnu.org>
2694
2695 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
2696 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
2697
2698 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
2699
2700 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
2701 value for non-existent files.
2702
2703 2011-09-11 Eli Zaretskii <eliz@gnu.org>
2704
2705 * fileio.c (Finsert_file_contents): If the file cannot be opened,
2706 set its "size" to -1. This will set the modtime_size field of
2707 the corresponding buffer to -1, which is what
2708 verify-visited-file-modtime expects for files that do not exist.
2709 (Bug#9139)
2710
2711 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
2712
2713 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
2714 here ...
2715 * lisp.h: ... from here. push_key_description is no longer
2716 defined in keyboard.c, so its declaration should not be in
2717 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
2718 logically belongs with push_key_description.
2719
2720 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
2721
2722 * buffer.h: Include <sys/types.h> instead of <time.h>.
2723 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
2724 Problem reported by Herbert J. Skuhra.
2725
2726 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
2727
2728 * xml.c (parse_region): Make the parsing work for
2729 non-comment-starting XML files again (bug#9144).
2730
2731 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
2732
2733 * image.c (gif_load): Fix calculation of bottom and right corner.
2734 (Bug#9468)
2735
2736 2011-09-10 Eli Zaretskii <eliz@gnu.org>
2737
2738 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
2739 redisplay in small windows.
2740
2741 2011-09-09 Eli Zaretskii <eliz@gnu.org>
2742
2743 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
2744
2745 2011-09-08 Martin Rudalics <rudalics@gmx.at>
2746
2747 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
2748 Operate on live windows only.
2749
2750 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
2751
2752 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
2753
2754 2011-09-07 Eli Zaretskii <eliz@gnu.org>
2755
2756 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
2757 only under bidi iteration.
2758
2759 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
2760
2761 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
2762
2763 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
2764
2765 isnan: Fix porting problem to Solaris 10 with bundled gcc.
2766 Without this fix, the command to link temacs failed due to an
2767 undefined symbol __builtin_isnan. This is because
2768 /usr/include/iso/math_c99.h #defines isnan(x) to
2769 __builtin_isnan(x), but the bundled gcc, which identifies itself
2770 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
2771 a __builtin_isnan.
2772 * floatfns.c (isnan): #undef, and then #define to a clone of
2773 what's in data.c.
2774 (Fisnan): Always define, since it's always available now.
2775 (syms_of_floatfns): Always define isnan at the Lisp level.
2776
2777 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
2778
2779 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
2780
2781 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
2782
2783 * fileio.c: Fix bugs with large file offsets (Bug#9428).
2784 The previous code assumed that file offsets (off_t values) fit in
2785 EMACS_INT variables, which is not true on typical 32-bit hosts.
2786 The code messed up by falsely reporting buffer overflow in cases
2787 such as (insert-file-contents "big" nil 1 2) into an empty buffer
2788 when "big" contains more than 2**29 bytes, even though this
2789 inserts just one byte and does not overflow the buffer.
2790 (Finsert_file_contents): Store file offsets as off_t
2791 values, not as EMACS_INT values. Check for overflow when
2792 converting between EMACS_INT and off_t. When checking for
2793 buffer overflow or for overlap, take the offsets into account.
2794 Don't use EMACS_INT for small values where int suffices.
2795 When checking for overlap, fix a typo: ZV was used where
2796 ZV_BYTE was intended.
2797 (Fwrite_region): Don't assume off_t fits into 'long'.
2798 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
2799
2800 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
2801
2802 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
2803
2804 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
2805
2806 sprintf-related integer and memory overflow issues (Bug#9412).
2807
2808 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
2809 (esprintf, exprintf, evxprintf): New functions.
2810 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
2811 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
2812 (modify_event_symbol): Do not assume that the length of
2813 name_alist_or_stem is safe to alloca and fits in int.
2814 (Fexecute_extended_command): Likewise for function name and binding.
2815 (Frecursion_depth): Wrap around reliably on integer overflow.
2816 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
2817 since some callers pass EMACS_INT values.
2818 (Fsingle_key_description): Don't crash if symbol name contains more
2819 than MAX_ALLOCA bytes.
2820 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
2821 (get_minibuffer): Arg is now EMACS_INT, not int.
2822 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
2823 (esprintf, exprintf, evxprintf): New decls.
2824 * window.h (command_loop_level, minibuf_level): Reflect API changes.
2825
2826 * dbusbind.c (signature_cat): New function.
2827 (xd_signature, Fdbus_register_signal):
2828 Do not overrun buffer; instead, report string overflow.
2829
2830 * dispnew.c (add_window_display_history): Don't overrun buffer.
2831 Truncate instead; this is OK since it's just a log.
2832
2833 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
2834 even if the time zone offset is outlandishly large.
2835 Don't mishandle offset == INT_MIN.
2836
2837 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
2838 when creating daemon; the previous buffer-overflow check was incorrect.
2839
2840 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
2841 which has the guts of the old verror function.
2842
2843 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
2844 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
2845
2846 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
2847 (font_unparse_xlfd): Don't blindly alloca long strings.
2848 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
2849 fits in int, when using sprintf. Use single snprintf to count
2850 length of string rather than counting it via multiple sprintfs;
2851 that's simpler and more reliable.
2852 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
2853 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
2854 sprintf, in case result does not fit in int.
2855
2856 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
2857 (fontset_from_font): Print it.
2858
2859 * frame.c (tty_frame_count): Now printmax_t, not int.
2860 (make_terminal_frame, set_term_frame_name): Print it.
2861 (x_report_frame_params): In X, window IDs are unsigned long,
2862 not signed long, so print them as unsigned.
2863 (validate_x_resource_name): Check for implausibly long names,
2864 and don't assume name length fits in 'int'.
2865 (x_get_resource_string): Don't blindly alloca invocation name;
2866 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
2867 not fit in int.
2868
2869 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
2870 (xg_check_special_colors, xg_set_geometry):
2871 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
2872
2873 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
2874 Use esprintf, not sprintf, in case result does not fit in int.
2875
2876 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
2877 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
2878 it as a large positive number.
2879 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
2880 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
2881
2882 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
2883 in case result does not fit in int.
2884
2885 * print.c (float_to_string): Detect width overflow more reliably.
2886 (print_object): Make sprintf buffer a bit bigger, to avoid potential
2887 buffer overrun. Don't assume list length fits in 'int'. Treat
2888 print length of 0 as 0, not as infinity; to be consistent with other
2889 uses of print length in this function. Don't overflow print length
2890 index. Don't assume hash table size fits in 'long', or that
2891 vectorlike size fits in 'unsigned long'.
2892
2893 * process.c (make_process): Use printmax_t, not int, to format
2894 process-name gensyms.
2895
2896 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
2897
2898 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
2899 to avoid potential buffer overrun.
2900
2901 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
2902 if X resource line is longer than 512 bytes.
2903
2904 * xfns.c (x_window): Make sprintf buffer a bit bigger
2905 to avoid potential buffer overrun.
2906
2907 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
2908
2909 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
2910
2911 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
2912
2913 Integer overflow fixes for scrolling, etc.
2914 Without these, Emacs silently mishandles large integers sometimes.
2915 For example, "C-u 4294967297 M-x recenter" was treated as if
2916 it were "C-u 1 M-x recenter" on a typical 64-bit host.
2917
2918 * xdisp.c (try_window_id): Check Emacs fixnum range before
2919 converting to 'int'.
2920
2921 * window.c (window_scroll_line_based, Frecenter):
2922 Check that an Emacs fixnum is in range before assigning it to 'int'.
2923 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
2924 values converted from Emacs fixnums.
2925 (Frecenter): Don't wrap around a line count if it is out of 'int'
2926 range; instead, treat it as an extreme value.
2927 (Fset_window_configuration, compare_window_configurations):
2928 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
2929
2930 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
2931 that can exceed INT_MAX. Check that EMACS_INT value is in range
2932 before assigning it to the (possibly-narrower) index.
2933 (match_limit): Don't assume that a fixnum can fit in 'int'.
2934
2935 * print.c (print_object): Use ptrdiff_t, not int, for index that can
2936 exceed INT_MAX.
2937
2938 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
2939 (Fvertical_motion): Don't wrap around LINES values that don't fit
2940 in 'int'. Instead, treat them as extreme values. This is good
2941 enough for windows, which can't have more than INT_MAX lines anyway.
2942
2943 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
2944
2945 * Require libxml/parser.h to avoid compilation warning.
2946
2947 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
2948
2949 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
2950 since this reportedly can destroy thread storage.
2951
2952 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
2953
2954 * syntax.c (find_defun_start): Update all cache variables if

2956
2957 2011-08-30 Eli Zaretskii <eliz@gnu.org>
2958
2959 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
2960
2961 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
2962 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
2963 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
2964
2965 * term.c (tty_append_glyph): New function.
2966 (produce_stretch_glyph): Static function and its prototype deleted.
2967
2968 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
2969 Add prototypes.
2970
2971 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
2972
2973 * image.c (parse_image_spec): Check for nonnegative, not for positive,
2974 when checking :margin (Bug#9390).
2975 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
2976 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
2977 so that the name doesn't mislead. All uses changed.
2978

2981 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
2982 set_tty_hooks.
2983
2984 2011-08-27 Eli Zaretskii <eliz@gnu.org>
2985
2986 * xdisp.c (move_it_to): Don't bail out early when reaching
2987 position beyond to_charpos, if we are scanning backwards.
2988 (move_it_vertically_backward): When DY == 0, make sure we get to
2989 the first character in the line after the newline.
2990
2991 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
2992
2993 * ccl.c: Improve and simplify overflow checking (Bug#9196).
2994 (ccl_driver): Do not generate an out-of-range pointer.
2995 (Fccl_execute_on_string): Remove unnecessary check for
2996 integer overflow, noted by Stefan Monnier in
2997 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
2998 Remove a FIXME that didn't need fixing.

3001 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
3002

3004
3005 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
3006
3007 Integer and memory overflow issues (Bug#9196).
3008
3009 * doc.c (get_doc_string): Rework so that
3010 get_doc_string_buffer_size is the actual buffer size, rather than
3011 being 1 less than the actual buffer size; this makes xpalloc more
3012 convenient.
3013
3014 * image.c (x_allocate_bitmap_record, cache_image):
3015 * xselect.c (Fx_register_dnd_atom):
3016 Simplify previous changes by using xpalloc.
3017
3018 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
3019 since either will do and ptrdiff_t is convenient with xpalloc.
3020
3021 * charset.c (charset_table_size)
3022 (struct charset_sort_data.priority): Now ptrdiff_t.
3023 (charset_compare): Don't overflow if priorities differ greatly.
3024 (Fsort_charsets): Don't assume list length fits in int.
3025 Check for size-calculation overflow when allocating sort data.
3026 (syms_of_charset): Allocate an initial charset table that is
3027 just under 64 KiB, to avoid problems with glibc malloc and mmap.
3028
3029 * cmds.c (internal_self_insert): Check for size-calculation overflow.
3030
3031 * composite.h (struct composition.glyph_len): Now int, not unsigned.
3032 The actual value is always <= INT_MAX, and leaving it unsigned made
3033 overflow checking harder.
3034
3035 * dispextern.h (struct glyph_matrix.rows_allocated)
3036 (struct face_cache.size): Now ptrdiff_t, for convenience in use
3037 with xpalloc. The values are still always <= INT_MAX.
3038
3039 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
3040
3041 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
3042 (SAFE_NALLOCA): New macro.
3043
3044 * region-cache.c (struct boundary.pos, find_cache_boundary)
3045 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
3046 (set_cache_region, invalidate_region_cache)
3047 (revalidate_region_cache, know_region_cache, region_cache_forward)
3048 (region_cache_backward, pp_cache):
3049 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
3050 so that ptrdiff_t * can be passed to xpalloc.
3051 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
3052 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
3053 (pp_cache): Don't assume cache_len fits in int.
3054 * region-cache.h: Adjust extern decls to match.
3055
3056 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
3057 EMACS_INT, since either will do, for xpalloc.
3058
3059 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
3060 (xnmalloc, xnrealloc, xpalloc): New functions.
3061
3062 * bidi.c (bidi_shelve_header_size): New constant.
3063 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
3064 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
3065
3066 * bidi.c (bidi_cache_shrink):
3067 * buffer.c (overlays_at, overlays_in, record_overlay_string)
3068 (overlay_strings):
3069 Don't update size of array until after memory allocation succeeds,
3070 because xmalloc/xrealloc may not return.
3071 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
3072 now that we have proper integer overflow checking.
3073 (record_overlay_string, overlay_strings): Catch overflows when
3074 calculating size of overlay_str_buf.
3075
3076 * callproc.c (Fcall_process): Check for size overflow when
3077 calculating size of args2.
3078 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
3079 Normally we prefer signed values, but sticking with ptrdiff_t would
3080 require adding more-complicated checks.
3081
3082 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
3083 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
3084 Redo buffer-overflow calculations to avoid integer overflow.
3085 Add a FIXME comment where memory seems to be over-allocated.
3086
3087 * character.c (Fstring): Check for size-calculation overflow.
3088
3089 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
3090 unnecessary integer overflow. Check for size overflow.
3091 (encode_coding_object): Don't update size until xmalloc succeeds.
3092
3093 * composite.c (get_composition_id): Check for overflow in glyph
3094 length calculations.
3095
3096 Integer and memory overflow fixes for display code.
3097 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
3098 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
3099 (scrolling_window): Check for overflow in size calculations.
3100 (line_draw_cost, realloc_glyph_pool, add_row_entry):
3101 Don't assume glyph table len fits in int.
3102 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
3103 (row_table_size): Now ptrdiff_t, not int.
3104 (scrolling_window): Avoid overflow in size calculations.
3105 Don't update size until allocation succeeds.
3106 * fns.c (concat): Check for overflow in size calculations.
3107 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
3108 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
3109 (NEXT_ALMOST_PRIME_LIMIT): New constant.
3110
3111 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
3112 (get_doc_string): Check for size calculation overflow.
3113 Don't update size until allocation succeeds.
3114 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
3115 EMACS_INT, where ptrdiff_t will do.
3116 (Fsubstitute_command_keys): Check for string overflow.
3117
3118 * editfns.c (set_time_zone_rule): Don't assume environment length
3119 fits in int.
3120 (message_length): Now ptrdiff_t, not int.
3121 (Fmessage_box): Don't update size until allocation succeeds.
3122 Don't assume message length fits in int.
3123 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
3124
3125 * emacs.c (main): Do not reallocate argv, since there is a null at
3126 the end that can be overwritten, and this way there's no need to
3127 worry about size-calculation overflow.
3128 (sort_args): Check for size-calculation overflow.
3129
3130 * eval.c (init_eval_once, grow_specpdl): Don't update size until
3131 alloc succeeds.
3132 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
3133
3134 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
3135 (x_set_scroll_bar_width, x_figure_window_size):
3136 Check for integer overflow.
3137 (x_set_alpha): Do not assume XINT fits in int.
3138
3139 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
3140 This is for the members text_lines, text_cols, total_lines, total_cols,
3141 where the system imposes an 'int' limit.
3142
3143 * fringe.c (Fdefine_fringe_bitmap):
3144 Don't update size until alloc works.
3145
3146 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
3147 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
3148
3149 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
3150 Check for size-calculation overflow.
3151 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
3152 do, as we prefer signed integers.
3153 (id_to_widget.max_size, id_to_widget.used)
3154 (xg_store_widget_in_map, xg_remove_widget_from_map)
3155 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
3156 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
3157 Use and return ptrdiff_t, not int.
3158 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
3159 * gtkutil.h: Change prototypes to match the above.
3160
3161 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
3162 are duplicate now that they've been promoted to lisp.h.
3163 (x_allocate_bitmap_record, x_alloc_image_color)
3164 (make_image_cache, cache_image, xpm_load):
3165 Don't update size until alloc is done.
3166 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
3167 (x_detect_edges):
3168 Check for size calculation overflow.

3174 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
3175 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
3176 Use ptrdiff_t, not int, to count maps.
3177 (read_char_minibuf_menu_prompt): Check for overflow in size
3178 calculations. Don't update size until allocation succeeds.
3179 Redo calculations to avoid overflow.
3180 * keyboard.h: Change prototypes to match the above.
3181
3182 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
3183 to count maps.
3184 (current_minor_maps): Check for size calculation overflow.
3185 * keymap.h: Change prototypes to match the above.
3186
3187 * lread.c (read1, init_obarray): Don't update size until alloc done.
3188
3189 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

3207
3208 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
3209 for command line length. Do not attempt to address one before the
3210 beginning of an array, as that's not portable.
3211
3212 * term.c (max_frame_lines): Remove; unused.
3213 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
3214 not int.
3215 (encode_terminal_code, calculate_costs): Check for size
3216 calculation overflow.
3217 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph

3221
3222 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
3223 subtracting pointers.
3224 (gobble_line): Check for overflow more carefully. Don't update size
3225 until alloc done.
3226
3227 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
3228 Don't update size until alloc done.
3229 Redo size calculations to avoid overflow.
3230 Check for size calculation overflow.
3231 (main) [DEBUG]: Fix typo in invoking tparam1.
3232

3239 (Finternal_make_lisp_face, cache_face):
3240 Check for size calculation overflow.
3241 (cache_face): Treat size calculation overflows as if they were
3242 memory exhaustion (the usual treatment), rather than aborting.
3243
3244 * xfns.c (x_encode_text, x_set_name_internal)
3245 (Fx_change_window_property): Use ptrdiff_t, not int, to count
3246 sizes, since they can exceed INT_MAX in size. Check for size
3247 calculation overflow.
3248
3249 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
3250 (xg_select): Check for size calculation overflow.
3251 Don't update size until alloc done.
3252
3253 * xrdb.c (get_environ_db): Don't assume path length fits in int,
3254 as sprintf is limited to int lengths.
3255
3256 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
3257 (X_LONG_MIN): New macros.
3258 Use them to make the following changes clearer.
3259 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
3260 This change doesn't affect the value now, but it may help remind
3261 future maintainers not to raise the value too much later.
3262 (SELECTION_QUANTUM): Remove, replacing with ...
3263 (selection_quantum): ... new function, which avoids overflow.
3264 All uses changed.
3265 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
3266 assumption that selection length fits in 'int'.

3268 (x_get_window_property, receive_incremental_selection)
3269 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
3270 (lisp_data_to_selection_data, clean_local_selection_data):
3271 Use ptrdiff_t, not int, to record length of selection.
3272 (x_reply_selection_request, x_get_window_property)
3273 (receive_incremental_selection, x_property_data_to_lisp):
3274 Redo calculations to avoid overflow.
3275 (x_reply_selection_request): When sending hint, ceiling it at
3276 X_LONG_MAX rather than relying on wraparound overflow to send
3277 something.
3278 (x_get_window_property, receive_incremental_selection)
3279 (lisp_data_to_selection_data, x_property_data_to_lisp):

3283 Don't store size until memory allocation succeeds.
3284 (x_get_window_property): Plug memory leak on memory exhaustion.
3285 Don't double-block input; malloc is safe here. Don't assume 2**34
3286 - 4 fits in unsigned long. Add an xassert to check
3287 XGetWindowProperty overflow. Be more careful about overflow
3288 calculations, and distinguish size from memory overflow better.
3289 (receive_incremental_selection): When tracing, don't assume
3290 unsigned int is less than INT_MAX.
3291 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
3292 harmful) conversions of unsigned short to int.
3293 (lisp_data_to_selection_data): Don't assume that integers
3294 in the range -65535 through -1 fit in an X unsigned short.
3295 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
3296 result parameters unless successful. Rely on cons_to_unsigned
3297 to report problems with elements; the old code wasn't right anyway.
3298 (x_check_property_data): Check for int overflow; we cannot use
3299 a wider type due to X limits.
3300 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
3301
3302 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

3308 Don't assume alloca size is less than MAX_ALLOCA.
3309 (x_term_init): Don't assume length fits in int (sprintf is limited
3310 to int size).
3311
3312 Use ptrdiff_t for composition IDs.

3314 * composite.c (composition_table_size, n_compositions)

3331 * image.c (xpm_get_color_table_h):
3332 * lisp.h (hash_lookup, hash_put):
3333 * minibuf.c (Ftest_completion):
3334 Use ptrdiff_t for hash table indexes, not int (which is too
3335 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
3336 32-bit --with-wide-int hosts).
3337
3338 * charset.c (Fdefine_charset_internal): Check for integer overflow.
3339 Add a FIXME comment about memory leaks.
3340 (syms_of_charset): Don't assume xmalloc returns.
3341
3342 Don't assume that stated character widths fit in int.
3343 * character.c (Fchar_width, c_string_width, lisp_string_width):
3344 * character.h (CHAR_WIDTH):
3345 * indent.c (MULTIBYTE_BYTES_WIDTH):
3346 Use sanitize_char_width to avoid undefined and/or bad behavior
3347 with outlandish widths.
3348 * character.h (sanitize_tab_width): Rename from sanitize_width,
3349 now that we have two such functions. All uses changed.
3350 (sanitize_char_width): New inline function.
3351
3352 Don't assume that tab-width fits in int.
3353 * character.h (sanitize_width): New inline function.
3354 (SANE_TAB_WIDTH): New macro.
3355 (ASCII_CHAR_WIDTH): Use it.
3356 * indent.c (sane_tab_width): Remove. All uses replaced by
3357 SANE_TAB_WIDTH (current_buffer).
3358 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
3359
3360 * fileio.c: Integer overflow issues with file modes.
3361 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
3362

3368 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
3369 (x_send_scroll_bar_event): Likewise. Check that the size does not
3370 exceed limits imposed by XClientMessageEvent, as well as the usual
3371 ptrdiff_t and size_t limits.
3372
3373 * keyboard.c: Overflow, signedness and related fixes.
3374 (make_lispy_movement): Use same integer type in forward decl
3375 that is used in the definition.
3376 (read_key_sequence, keyremap_step):
3377 Change bufsize argument back to int, undoing my 2011-03-30 change.
3378 We prefer signed types, and int is wide enough here.
3379 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
3380 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
3381 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
3382 length, not size_t. Use ptrdiff_t for index, not int.
3383 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
3384 possibility of integer overflow.
3385
3386 Overflow, signedness and related fixes for images.
3387
3388 * dispextern.h (struct it.stack[0].u.image.image_id)

3393 (Fimage_metadata, free_image_cache, clear_image_cache, lookup_image)
3394 (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
3395 * nsmenu.m (update_frame_tool_bar):
3396 * xdisp.c (calc_pixel_width_or_height):
3397 * xfns.c (image_cache_refcount):

3412 Prefer int to unsigned where either will do.
3413 (tiff_handler): New function, combining the cores of the
3414 old tiff_error_handler and tiff_warning_handler.
3415 This function is rewritten to use vsnprintf and thereby avoid
3416 stack buffer overflows. It uses only the features of vsnprintf
3417 that are common to both POSIX and native Microsoft.
3418 (tiff_error_handler, tiff_warning_handler): Use it.
3419 (tiff_load, gif_load, imagemagick_load_image):
3420 Don't assume :index value fits in 'int'.
3421 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

3435
3436 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
3437 the display spec is of the form `(space ...)'.
3438 (handle_display_spec): Return the value returned by
3439 handle_single_display_spec, not just 1 or zero.
3440 (handle_single_display_spec): If the display spec is of the form
3441 `(space ...)', and specifies display in the text area, return 2
3442 rather than 1.
3443 (try_cursor_movement): Check for the need to scroll more
3444 accurately, and prefer exact match for point under bidi.
3445 Don't advance `row' beyond the last row of the window.
3446
3447 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
3448 into disp_prop; all users changed.
3449
3450 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

3463 buffers, return left-to-right.
3464 (set_cursor_from_row): Consider candidate row a win if its glyph
3465 represents a newline and point is on that newline. Fixes cursor
3466 positioning on the newline at EOL of R2L text within L2R
3467 paragraph, and vice versa.
3468 (try_cursor_movement): Check continued rows, in addition to
3469 continuation rows. Fixes unwarranted scroll when point enters a
3470 continued line of R2L text within an L2R paragraph, or vice versa.
3471 (cursor_row_p): Consider the case of point being equal to
3472 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
3473 from the end of a short line to the beginning of a continued line
3474 of R2L text within L2R paragraph.

3500
3501 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
3502 instead of CHAR_TO_BYTE. Fixes a crash when a completion
3503 candidate is selected by the mouse, and that candidate has a
3504 composed character under the mouse.
3505
3506 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
3507 coordinates reported by pos-visible-in-window-p for a composed

3516 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
3517 consider it a hit if to_charpos is anywhere in the range of the
3518 composed buffer positions.
3519
3520 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
3521
3522 * image.c (gif_load): Don't assume that each subimage has the same
3523 dimensions as the base image. Handle disposal method that is
3524 "undefined" by the gif spec (Bug#9335).

3535 from an Org mode buffer to a Speedbar frame.
3536
3537 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
3538 a composition, take its buffer position from IT->cmp_it.charpos.
3539 Fixes cursor positioning at the beginning of a line that begins
3540 with a composed character.
3541
3542 2011-08-18 Eli Zaretskii <eliz@gnu.org>
3543
3544 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
3545 character bidirectional type, use STRONG_L instead. Fixes crashes
3546 in a buffer produced by `describe-categories'.
3547
3548 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
3549 members before the level stack, so they would be saved and
3550 restored when copying iterator state. Fixes incorrect reordering
3551 around TABs covered by display properties.
3552

3683 Set IT->current to match the bidi iterator unconditionally.
3684 (push_display_prop): Allow GET_FROM_STRING as IT->method on
3685 entry. Force push_it to save on the stack the current
3686 buffer/string position, to be restored by pop_it. Fix flags in
3687 the iterator structure wrt the object coming from a display
3688 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
3689 properties. (Bug#9284)

3733 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
3734 word-wrap under bidirectional display. (Bug#9224)
3735
3736 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
3737 is non-zero, even if the data buffer is NULL. Fixes a crash in
3738 vertical-motion with longlines-mode. (Bug#9254)
3739

3752 contents. All callers changed.
3753
3754 * dispextern.h (bidi_unshelve_cache): Update prototype.

3816 * bidi.c (bidi_fetch_char): Accept an additional argument
3817 DISP_PROP_P, and pass it to compute_display_string_pos.
3818 Only handle text covered by a display string if DISP_PROP_P is returned
3819 non-zero. All callers of bidi_fetch_char changed.
3820
3821 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
3822
3823 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
3824
3825 2010-12-03 Don March <don@ohspite.net>
3826
3827 * keymap.c (Fdefine_key): Fix non-prefix key error message when
3828 last character M-[char] is translated to ESC [char] (bug#7541).
3829
3830 2011-08-02 Kenichi Handa <handa@m17n.org>
3831
3832 * lisp.h (uniprop_table): Extern it.
3833
3834 * chartab.c (uniprop_table): Make it non-static.
3835
3836 2011-08-01 Eli Zaretskii <eliz@gnu.org>
3837
3838 * xdisp.c (forward_to_next_line_start): Accept additional argument
3839 BIDI_IT_PREV, and store into it the state of the bidi iterator had
3840 on the newline.
3841 (reseat_at_next_visible_line_start): Use the bidi iterator state
3842 returned by forward_to_next_line_start to restore the state of
3843 it->bidi_it after backing up to previous newline. (Bug#9212)
3844
3845 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
3846
3847 * regex.c (re_comp): Protoize.
3848 (re_exec): Fix return type.
3849 (regexec): Fix type of `ret'. (Bug#9203)
3850
3851 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3852
3853 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
3854 This is needed if max-image-size is a floating-point number.
3855
3856 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
3857
3858 * print.c (print_object): Print empty symbol as ##.
3859
3860 * lread.c (read1): Read ## as empty symbol.
3861
3862 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
3863
3864 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
3865 setting frame foreground color (Bug#9175).
3866 (x_set_background_color): Likewise.
3867
3868 * nsmenu.m (-setText): Size tooltip dimensions precisely to
3869 contents (Bug#9176).
3870 (EmacsTooltip -init): Remove bezels and add shadows to
3871 tooltip windows.
3872
3873 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
3874 or scroll bar (Bug#8470).
3875
3876 * nsfont.m (nsfont_open): Remove assignment to voffset and
3877 unnecessary vars hshink, expand, hd, full_height, min_height.
3878 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
3879
3880 * nsterm.h (nsfont_info): Remove voffset field.
3881
3882 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
3883
3884 Implement strike-through and overline on NextStep (Bug#8863).
3885
3886 * nsfont.m (nsfont_open): Use underline position provided by font,
3887 instead of hard-coded value of 2.
3888 (nsfont_draw): Call ns_draw_text_decoration instead.
3889
3890 * nsterm.h: Add declaration for ns_draw_text_decoration.
3891
3892 * nsterm.m (ns_draw_text_decoration): New function for drawing
3893 underline, overline, and strike-through.
3894 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
3895 ns_draw_text_decoration. Change treatment of cursor drawing to
3896 accommodate underlining, etc.
3897
3898 2011-07-28 Eli Zaretskii <eliz@gnu.org>
3899
3900 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
3901 default.
3902
3903 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3904
3905 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
3906 Without this fix, if a signal arrives just after memory fills up,
3907 'malloc' might be invoked reentrantly.
3908
3909 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
3910 In other words, assume that every image size is allowed, on non-X
3911 hosts. This assumption is probably wrong, but it lets Emacs compile.
3912
3913 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
3914
3915 * regex.c (re_iswctype): Convert return values to boolean.
3916
3917 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
3918
3919 * xdisp.c (compute_display_string_pos): Don't use cached display
3920 string position if the buffer had its restriction changed.
3921 (Bug#9184)
3922
3923 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3924
3925 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3926
3927 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
3928
3929 Integer signedness and overflow and related fixes. (Bug#9079)
3930
3931 * bidi.c: Integer size and overflow fixes.
3932 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
3933 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
3934 (bidi_cache_find_level_change, bidi_cache_ensure_space)
3935 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
3936 (bidi_find_other_level_edge):
3937 Use ptrdiff_t instead of EMACS_INT where either will do.
3938 This works better on 32-bit hosts configured --with-wide-int.
3939 (bidi_cache_ensure_space): Check for size-calculation overflow.
3940 Use % rather than repeated addition, for better worst-case speed.
3941 Don't set bidi_cache_size until after xrealloc returns, because it
3942 might not return.
3943 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
3944 (bidi_cache_ensure_space): Also check that the bidi cache size
3945 does not exceed that of the largest Lisp string or buffer. See Eli
3946 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
3947
3948 * alloc.c (__malloc_size_t): Remove.
3949 All uses replaced by size_t. See Andreas Schwab's note
3950 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
3951
3952 * image.c: Improve checking for integer overflow.
3953 (check_image_size): Assume that f is nonnull, since
3954 it is always nonnull in practice. This is one less thing to
3955 worry about when checking for integer overflow later.
3956 (x_check_image_size): New function, which checks for integer
3957 overflow issues inside X.
3958 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
3959 This removes the need for a memory_full check.
3960 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
3961 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
3962 (xbm_read_bitmap_data): Change locals back to 'int', since
3963 their values must fit in 'int'.
3964 (xpm_load_image, png_load, tiff_load):
3965 Invoke x_create_x_image_and_pixmap earlier,
3966 to avoid much needless work if the image is too large.
3967 (tiff_load): Treat overly large images as if
3968 x_create_x_image_and_pixmap failed, not as malloc failures.
3969 (gs_load): Use x_check_image_size.
3970
3971 * gtkutil.c: Omit integer casts.
3972 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
3973 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
3974
3975 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
3976
3977 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
3978 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
3979 would wrongly return t on a 64-bit host.
3980
3981 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
3982 The plain *_OVERFLOW macros run afoul of GCC bug 49705
3983 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
3984 and therefore cause GCC to emit a bogus diagnostic in some cases.
3985
3986 * image.c: Integer signedness and overflow and related fixes.
3987 This is not an exhaustive set of fixes, but it's time to
3988 record what I've got.
3989 (lookup_pixel_color, check_image_size): Remove redundant decls.
3990 (check_image_size): Don't assume that arbitrary EMACS_INT values
3991 fit in 'int', or that arbitrary 'double' values fit in 'int'.
3992 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
3993 (tiff_load, imagemagick_load_image):
3994 Check for overflow in size calculations.
3995 (x_create_x_image_and_pixmap): Remove unnecessary test for
3996 xmalloc returning NULL; that can't happen.
3997 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
3998 (xpm_color_bucket): Use better integer hashing function.
3999 (xpm_cache_color): Don't possibly over-allocate memory.
4000 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
4001 (gif_memory_source):
4002 Use ptrdiff_t, not int or size_t, to record sizes.
4003 (png_load): Don't assume values greater than 2**31 fit in 'int'.
4004 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
4005 either works, as we prefer signed integers.
4006 (tiff_read_from_memory, tiff_write_from_memory):
4007 Return tsize_t, not size_t, since that's what the TIFF API wants.
4008 (tiff_read_from_memory): Don't fail simply because the read would
4009 go past EOF; instead, return a short read.
4010 (tiff_load): Omit no-longer-needed casts.
4011 (Fimagemagick_types): Don't assume size fits into 'int'.
4012
4013 Improve hashing quality when configured --with-wide-int.
4014 * fns.c (hash_string): New function, taken from sxhash_string.
4015 Do not discard information about ASCII character case; this
4016 discarding is no longer needed.
4017 (sxhash-string): Use it. Change sig to match it. Caller changed.
4018 * lisp.h: Declare it.
4019 * lread.c (hash_string): Remove, since we now use fns.c's version.
4020 The fns.c version returns a wider integer if --with-wide-int is
4021 specified, so this should help the quality of the hashing a bit.
4022
4023 * emacs.c: Integer overflow minor fix.
4024 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
4025 Define only if GNU_LINUX.
4026 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
4027
4028 * dispnew.c: Integer signedness and overflow fixes.
4029 Remove unnecessary forward decls, that were a maintenance hassle.
4030 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
4031 All uses changed.
4032 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
4033 (scrolling_window): Use ptrdiff_t, not int, for byte count.
4034 (prepare_desired_row, line_draw_cost):
4035 Use int, not unsigned, where either works.
4036 (save_current_matrix, restore_current_matrix):
4037 Use ptrdiff_t, not size_t, where either works.
4038 (init_display): Check for overflow more accurately, and without
4039 relying on undefined behavior.
4040
4041 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
4042 Remove, replacing with the new symbols in lisp.h. All uses changed.
4043 * fileio.c (make_temp_name):
4044 * filelock.c (lock_file_1, lock_file):
4045 * xdisp.c (message_dolog):
4046 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
4047 Use pMd etc. instead.
4048 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
4049 replacing the pWIDE etc. symbols removed from editfns.c.
4050
4051 * keyboard.h (num_input_events): Now uintmax_t.
4052 This is (very slightly) less likely to mess up due to wraparound.
4053 All uses changed.
4054
4055 * buffer.c: Integer signedness fixes.
4056 (alloc_buffer_text, enlarge_buffer_text):
4057 Use ptrdiff_t rather than size_t when either will do, as we prefer
4058 signed integers.
4059
4060 * alloc.c: Integer signedness and overflow fixes.
4061 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
4062 (__malloc_size_t): Default to size_t, not to int.
4063 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
4064 (Fgarbage_collect, mark_object_loop_halt, mark_object):
4065 Prefer ptrdiff_t to size_t when either would do, as we prefer
4066 signed integers.
4067 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
4068 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
4069 Now const. Initialize with values that are in range even if char
4070 is signed.
4071 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
4072 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
4073 These functions do the right thing with sizes > 2**32.
4074 (check_depth): Now ptrdiff_t, not int.
4075 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
4076 Adjust to new way of storing sizes. Check for size overflow bugs
4077 in rest of code.
4078 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
4079 slightly wrong anyway, as it missed one instance of
4080 XMALLOC_OVERRUN_CHECK_OVERHEAD.
4081 (refill_memory_reserve): Omit needless cast to size_t.
4082 (mark_object_loop_halt): Mark as externally visible.
4083
4084 * xselect.c: Integer signedness and overflow fixes.
4085 (Fx_register_dnd_atom, x_handle_dnd_message):
4086 Use ptrdiff_t, not size_t, since we prefer signed.
4087 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
4088 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
4089 x_dnd_atoms_size and x_dnd_atoms_length.
4090
4091 * doprnt.c: Prefer signed to unsigned when either works.
4092 * eval.c (verror):
4093 * doprnt.c (doprnt):
4094 * lisp.h (doprnt):
4095 * xdisp.c (vmessage):
4096 Use ptrdiff_t, not size_t, when using or implementing doprnt,
4097 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
4098 prefer signed arithmetic to avoid comparison confusion.
4099 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
4100 but is a bit tricky.
4101
4102 Assume freestanding C89 headers, string.h, stdlib.h.
4103 * data.c, doprnt.c, floatfns.c, print.c:
4104 Include float.h unconditionally.
4105 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
4106 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
4107 * regex.c: Likewise for stddef.h, string.h.
4108 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
4109 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
4110 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
4111 (STDC_HEADERS): Remove obsolete defines.
4112 * sysdep.c: Include limits.h unconditionally.
4113
4114 Assume support for memcmp, memcpy, memmove, memset.
4115 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
4116 * regex.c (memcmp, memcpy):
4117 Remove; we assume C89 now.
4118
4119 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
4120 (__malloc_safe_bcopy): Remove; no longer needed.
4121
4122 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
4123 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
4124 well either way, and we prefer signed to unsigned.
4125
4126 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
4127
4128 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
4129 closes the connection while we're reading (bug#9182).
4130
4131 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
4132
4133 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
4134 are specified (Bug#9168).
4135
4136 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
4137
4138 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
4139 Found by GCC static checking and --with-wide-int on a 32-bit host.
4140
4141 2011-07-25 Eli Zaretskii <eliz@gnu.org>
4142
4143 * xdisp.c (compute_display_string_pos): Fix logic of caching
4144 previous display string position. Initialize cached_prev_pos to
4145 -1. Fixes slow-down at the beginning of a buffer.
4146
4147 2011-07-24 Eli Zaretskii <eliz@gnu.org>
4148
4149 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
4150 for attrs[LFACE_FONTSET_INDEX].
4151
4152 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
4153
4154 * xml.c (parse_region): Remove unused local
4155 that was recently introduced.
4156
4157 2011-07-23 Eli Zaretskii <eliz@gnu.org>
4158
4159 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
4160 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
4161
4162 * xdisp.c (move_it_in_display_line_to): Record the best matching
4163 position for TO_CHARPOS while scanning the line, and restore it on
4164 exit if none of the characters scanned was an exact match.
4165 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
4166 when exact match is impossible due to invisible text, and the
4167 lines are truncated.
4168
4169 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
4170
4171 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
4172 for OSX >= 10.7.
4173
4174 2011-07-22 Eli Zaretskii <eliz@gnu.org>
4175
4176 Fix a significant slow-down of cursor motion with C-n, C-p,
4177 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
4178 auto-repeat under bidi redisplay in fontified buffers.
4179 * xdisp.c (compute_stop_pos_backwards): New function.
4180 (next_element_from_buffer): Call compute_stop_pos_backwards to
4181 find a suitable prev_stop when we find ourselves before
4182 base_level_stop.
4183 (reseat): Don't look for prev_stop, as that could mean a very long
4184 run.
4185 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
4186 <cached_disp_overlay_modiff>: Cache for last found display string
4187 position.
4188 (compute_display_string_pos): Return the cached position if asked
4189 about the same buffer in the same area of character positions, and
4190 the buffer wasn't changed since the time the display string
4191 position was cached.
4192
4193 2011-07-22 Eli Zaretskii <eliz@gnu.org>
4194
4195 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
4196 is an integer, which is important for empty lines. (Bug#9149)
4197
4198 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
4199
4200 * frame.c (Fmodify_frame_parameters): In tty case, update the
4201 default face if necessary (Bug#4238).
4202
4203 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
4204
4205 * editfns.c (Fstring_to_char): No need to explain what a character
4206 is in the docstring (Bug#6576).
4207
4208 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
4209
4210 * xml.c (parse_region): Make sure we always return a tree.
4211
4212 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
4213
4214 * xml.c (parse_region): If a document contains only comments,
4215 return that, too.
4216
4217 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
4218
4219 * xml.c (make_dom): Return comments, too.
4220
4221 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
4222
4223 Port to OpenBSD.
4224 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
4225 and the surrounding thread.
4226 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
4227 rather than fgets, and retry after EINTR. Otherwise, 'emacs
4228 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
4229 timer goes off.
4230 * s/openbsd.h (BROKEN_SIGIO): Define.
4231 * unexelf.c (unexec) [__OpenBSD__]:
4232 Don't update the .mdebug section of the Alpha COFF symbol table.
4233
4234 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
4235
4236 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
4237 (bug#8460).
4238
4239 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
4240
4241 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
4242 This fixes some race conditions on the permissions of any newly
4243 created file.
4244
4245 * alloc.c (valid_pointer_p): Use pipe, not open.
4246 This fixes some permissions issues when debugging.
4247
4248 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
4249 If fchown fails to set both uid and gid, try to set just gid,
4250 as that is sometimes allowed. Adjust the file's mode to eliminate
4251 setuid or setgid bits that are inappropriate if fchown fails.
4252
4253 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
4254
4255 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
4256 to compare Lisp_Objects.
4257 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
4258 global_gnutls_log_level, don't mistake it for a Lisp_Object.
4259 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
4260
4261 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
4262
4263 * lread.c (read_integer): Unread even EOF character.
4264 (read1): Likewise. Properly record start position of symbol.
4265
4266 * lread.c (read1): Read `#:' as empty uninterned symbol if no
4267 symbol character follows.
4268
4269 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
4270
4271 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
4272 This works around a problem with the previous change to Fcopy_file.
4273 Recent glibc declares fchown with __attribute__((warn_unused_result)),
4274 and without this change, GCC might complain about discarding
4275 fchown's return value.
4276
4277 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
4278
4279 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
4280
4281 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
4282
4283 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
4284
4285 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
4286
4287 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
4288 it's used from the C level.
4289
4290 * process.c: Use the same condition for POLL_FOR_INPUT in both
4291 keyboard.c and process.c (bug#1858).
4292
4293 2011-07-09 Lawrence Mitchell <wence@gmx.li>
4294
4295 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
4296 (Fgnutls_boot): Use it.
4297
4298 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
4299
4300 * doc.c (Fsubstitute_command_keys): Revert last change.
4301
4302 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
4303
4304 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
4305 quotes the next character, and doesn't affect other longer
4306 sequences (bug#8935).
4307
4308 * lread.c (syms_of_lread): Clarify that is isn't only
4309 `eval-buffer' and `eval-defun' that's affected by
4310 `lexical-binding' (bug#8460).
4311
4312 2011-07-15 Eli Zaretskii <eliz@gnu.org>
4313
4314 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
4315 bidi redisplay when a line includes both an image and is truncated.
4316
4317 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
4318
4319 Fix minor problems found by static checking.
4320 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
4321 (elsz): Now a signed constant, not a size_t var. We prefer signed
4322 types to unsigned, to avoid integer comparison confusion. Without
4323 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
4324 "cannot optimize loop, the loop counter may overflow", a symptom
4325 of the confusion.
4326 * indent.c (Fvertical_motion): Mark locals as initialized.
4327 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
4328
4329 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
4330
4331 * search.c (Fre_search_backward): Mention `case-fold-search' in
4332 all the re_search_* functions (bug#8138).
4333
4334 * keyboard.c (Fopen_dribble_file): Document when the file is
4335 closed (bug#8056).
4336
4337 2011-07-14 Eli Zaretskii <eliz@gnu.org>

4339 * bidi.c (bidi_dump_cached_states): Fix format of displaying
4340 bidi_cache_idx.
4341
4342 Support bidi reordering of display and overlay strings.
4343 * xdisp.c (compute_display_string_pos)
4344 (compute_display_string_end): Accept additional argument STRING.
4345 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.

4349 NULL (avoids a crash in bidi_paragraph_init).
4350 Initialize itb.string.lstring.
4351 (init_iterator): Call bidi_init_it only of a valid
4352 buffer position was specified. Initialize paragraph_embedding to
4353 L2R.
4354 (reseat_to_string): Initialize the bidi iterator.
4355 (display_string): If we need to ignore text properties of
4356 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
4357 original value of -1 will not work with bidi.)
4358 (compute_display_string_pos): First arg is now struct
4359 `text_pos *'; all callers changed. Support display properties on
4360 Lisp strings.
4361 (compute_display_string_end): Support display properties on Lisp
4362 strings.
4363 (init_iterator, reseat_1, reseat_to_string): Initialize the
4364 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
4365 when iterating on a string not from display properties).
4366 (compute_display_string_pos, compute_display_string_end):
4367 Fix calculation of the object to scan. Fixes an error when using
4368 arrow keys.
4369 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
4370 base_level_stop; instead, set base_level_stop to BEGV.
4371 Fixes crashes in vertical-motion.
4372 (next_element_from_buffer): Improve commentary for when
4373 the iterator is before prev_stop.
4374 (init_iterator): Initialize bidi_p from the default value of
4375 bidi-display-reordering, not from buffer-local value. Use the
4376 buffer-local value only if initializing for buffer iteration.
4377 (handle_invisible_prop): Support invisible properties on strings
4378 that are being bidi-reordered.
4379 (set_iterator_to_next): Support bidi reordering of C strings and
4380 Lisp strings.

4392 structure.
4393 (face_before_or_after_it_pos): Support bidi iteration.
4394 (next_element_from_c_string): Handle the case of the first string
4395 character that is not the first one in the visual order.
4396 (get_visually_first_element): New function, refactored from common
4397 parts of next_element_from_buffer, next_element_from_string, and
4398 next_element_from_c_string.
4399 (tool_bar_lines_needed, redisplay_tool_bar)
4400 (display_menu_bar): Force left-to-right direction. Add a FIXME
4401 comment for making that be controlled by a user option.
4402 (push_it, pop_it): Save and restore the state of the
4403 bidi iterator. Save and restore the bidi_p flag.
4404 (pop_it): Iterate out of display property for string iteration as

4411 iterator for displaying display or overlay strings.
4412 (forward_to_next_line_start): Don't use the shortcut if
4413 bidi-iterating.
4414 (back_to_previous_visible_line_start): If handle_display_prop
4415 pushed the iterator stack, restore the internal state of the bidi
4416 iterator by calling bidi_pop_it same number of times.
4417 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
4418 and we are bidi-iterating, don't decrement the iterator position;
4419 instead, set the first_elt flag in the bidi iterator, to produce
4420 the same effect.
4421 (reseat_1): Remove redundant setting of string_from_display_prop_p.
4422 (push_display_prop): xassert that we are iterating a buffer.
4423 (push_it, pop_it): Save and restore paragraph_embedding member.
4424 (handle_single_display_spec, next_overlay_string)
4425 (get_overlay_strings_1, reseat_1, reseat_to_string)

4434 (pop_it): Call iterate_out_of_display_property only if we are
4435 popping after iteration over a string that came from a display
4436 property. Fix a typo in popping stretch info. Add an assertion
4437 for verifying that the iterator position is in sync with the bidi
4438 iterator.
4439 (handle_single_display_spec, get_overlay_strings_1)
4440 (push_display_prop): Fix initialization of paragraph direction for
4441 string when that of the parent object is not yet determined.
4442 (reseat_1): Call bidi_init_it to resync the bidi
4443 iterator with IT's position. (Bug#7616)
4444 (find_row_edges): If ROW->start.pos gives position
4445 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
4446 (handle_stop, back_to_previous_visible_line_start, reseat_1):
4447 Reset the from_disp_prop_p flag.
4448 (SAVE_IT, RESTORE_IT): New macros.

4456 (init_iterator): Empty the bidi cache "stack".
4457 (move_it_in_display_line_to): If iterator ended up at
4458 EOL, but we never saw any buffer positions smaller than
4459 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
4460 motion in bidi-reordered lines.
4461 (move_it_in_display_line_to): Record prev_method and prev_pos
4462 immediately before the call to set_iterator_to_next. Fixes cursor
4463 motion in bidi-reordered lines with stretch glyphs and strings
4464 displayed in margins. (Bug#8133) (Bug#8867)
4465 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
4466 TO_CHARPOS.
4467 (pos_visible_p): Support positions in bidi-reordered lines.
4468 Save and restore bidi cache.
4469
4470 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.

4480 (bidi_move_to_visually_next): Compare cache index with
4481 bidi_cache_start rather than with zero.
4482 (bidi_fetch_char): Accept new argument STRING; all callers
4483 changed. Support iteration over a string. Support strings with
4484 display properties. Support unibyte strings. Fix the type of
4485 `len' according to what STRING_CHAR_AND_LENGTH expects.
4486 (bidi_paragraph_init, bidi_resolve_explicit_1)
4487 (bidi_resolve_explicit, bidi_resolve_weak)
4488 (bidi_level_of_next_char, bidi_move_to_visually_next):

4506 (bidi_initialize): Initialize the bidi cache start stack pointer.
4507 (bidi_cache_ensure_space): New function, refactored from part of

4527 Update prototypes.
4528 (bidi_push_it, bidi_pop_it): Add prototypes.
4529 (struct iterator_stack_entry): New members bidi_p,
4530 paragraph_embedding, and from_disp_prop_p.

4581 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
4582
4583 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
4584 The old code sometimes used this field without initializing it.
4585
4586 * alloc.c (gc_sweep): Don't read past end of array.
4587 In theory, the old code could also have corrupted Emacs internals,
4588 though it'd be very unlikely.
4589
4590 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
4591

4851 (clone_per_buffer_values): Don't assume that

4853 This isn't true in general, and it's particularly not true
4854 if Emacs is configured with --with-wide-int.
4855 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
4856 New macros, used in the buffer.c change.

4890 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
4891
4892 Random fixes. E.g., (random) never returned negative values.
4893 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
4894 subseconds part to the entropy, as that's a bit more random.
4895 Prefer signed to unsigned, since the signedness doesn't matter and
4896 in general we prefer signed. When given a limit, use a
4897 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
4898 latter isn't right if USE_2_TAGS_FOR_INTS.
4899 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
4900 not 0..VALMASK. Don't discard "excess" bits that random () returns.

4909
4910 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
4911
4912 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
4913 This is more efficient than Ffile_directory_p and avoids a minor race.
4914
4915 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
4916
4917 * buffer.c (Foverlay_put): Say what the return value is

4924 error be more correct.

4936
4937 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
4938 (syms_of_gnutls): Remove duplicate DEFSYM for
4939 Qgnutls_bootprop_verify_hostname_error, an error for
4940 Qgnutls_bootprop_verify_error (which is no longer used).
4941
4942 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
4943 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
4944 Also (re)move comments that are misplaced or no longer relevant.
4945

4961 * xsettings.c (SYSTEM_FONT): Define only when used.
4962 No need to define when HAVE_GSETTINGS || !HAVE_XFT.
4963

4965
4966 2011-07-02 Chong Yidong <cyd@stupidchicken.com>
4967

4998 (access_keymap): Use it.
4999 (Fkeymap_prompt, map_keymap_internal, map_keymap, store_in_keymap)
5000 (Fcopy_keymap): Handle embedded parents.
5001 (Fcommand_remapping, define_as_prefix): Simplify.
5002 (Fkey_binding): Simplify.

5044
5045 * eval.c (struct backtrace): Simplify and port the data structure.
5046 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
5047 signed bit field, as this assumption is not portable and it makes
5048 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
5049 "char debug_on_exit : 1" as this is not portable either; instead,
5050 use the portable "unsigned int debug_on_exit : 1". Remove unused
5051 member evalargs. Remove obsolete comments about cc bombing out.

5126 and use min_width/height from frames size_hint to set
5127 min_width/height (Bug#8919).
5128
5129 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
5130 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.

5134
5135 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling

5217 Integer and buffer overflow fixes (Bug#8873).
5218
5219 * print.c (printchar, strout): Check for string overflow.
5220 (PRINTPREPARE, printchar, strout):
5221 Don't set size unless allocation succeeds.
5222
5223 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
5224 for sizes. Check for string overflow more accurately.
5225 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
5226
5227 * macros.c: Integer and buffer overflow fixes.
5228 * keyboard.h (struct keyboard.kbd_macro_bufsize):
5229 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

5233 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
5234
5235 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
5236
5237 * lread.c: Integer overflow fixes.
5238 (read_integer): Radix is now EMACS_INT, not int,
5239 to improve quality of diagnostics for out-of-range radices.
5240 Calculate buffer size correctly for out-of-range radices.
5241 (read1): Check for integer overflow in radices, and in
5242 read-circle numbers.
5243 (read_escape): Avoid int overflow.
5244 (Fload, openp, read_buffer_size, read1)
5245 (substitute_object_recurse, read_vector, read_list, map_obarray):
5246 Use ptrdiff_t, not int, for sizes.
5247 (read1): Use EMACS_INT, not int, for sizes.

5260
5261 2011-06-22 Leo Liu <sdl.web@gmail.com>
5262

5265
5266 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
5267
5268 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
5269 The following patches are for when GLYPH_DEBUG && !XASSERT.
5270 * dispextern.h (trace_redisplay_p, dump_glyph_string):
5271 * dispnew.c (flush_stdout):
5272 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
5273 Mark as externally visible.
5274 * dispnew.c (check_window_matrix_pointers): Now static.
5275 * dispnew.c (window_to_frame_vpos):
5276 * xfns.c (unwind_create_frame):
5277 * xterm.c (x_check_font): Remove unused local.
5278 * scroll.c (CHECK_BOUNDS):
5279 * xfaces.c (cache_fache): Rename local to avoid shadowing.
5280 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
5281 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
5282 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
5283 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
5284 Now static.
5285 (debug_method_add): Use va_list and vsprintf rather than relying
5286 on undefined behavior with wrong number of arguments.
5287 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
5288 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
5289 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
5290 since we're not interested in debugging glyphs with old libraries.
5291 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
5292 GCC 4.6.0's static checking.
5293
5294 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
5295
5296 Integer overflow and signedness fixes (Bug#8873).
5297 A few related buffer overrun fixes, too.
5298
5299 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
5300

5304 (x_create_bitmap_from_data, x_create_bitmap_from_file)
5305 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
5306 (x_create_bitmap_from_xpm_data):
5307 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
5308 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
5309 (.bitmaps_last):
5310 * xfaces.c (load_pixmap):
5311 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
5312 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
5313 (.bitmaps_last, struct x_output.icon_bitmap):
5314 Use ptrdiff_t, not int, for bitmap indexes.
5315 (x_allocate_bitmap_record): Check for size overflow.
5316 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
5317
5318 Use ptrdiff_t, not int, for overlay counts.
5319 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
5320 * editfns.c (overlays_around, get_pos_property):
5321 * textprop.c (get_char_property_and_overlay):
5322 * xdisp.c (next_overlay_change, note_mouse_highlight):
5323 * xfaces.c (face_at_buffer_position):
5324 * buffer.c (OVERLAY_COUNT_MAX): New macro.
5325 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
5326 (Fnext_overlay_change, Fprevious_overlay_change)
5327 (mouse_face_overlay_overlaps, Foverlays_in):
5328 Use ptrdiff_t, not int, for sizes.
5329 (overlays_at, overlays_in): Check for size-calculation overflow.
5330
5331 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
5332
5333 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
5334 (x_session_initialize): Do not assume string length fits in int.
5335
5336 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
5337 This is unlikely, but can occur if DPI is outlandish.
5338
5339 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
5340 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
5341
5342 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
5343 * xrdb.c (magic_file_p, search_magic_path):
5344 Omit last arg SUFFIX; it was always 0. All callers changed.
5345 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
5346
5347 * xfont.c (xfont_match): Avoid need for strlen.
5348
5349 * xfns.c: Don't assume strlen fits in int.
5350 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
5351
5352 * xdisp.c (message_log_check_duplicate): Return intmax_t,
5353 not unsigned long, as we prefer signed integers. All callers changed.
5354 Detect integer overflow in repeat count.
5355 (message_dolog): Don't assume print length fits in 39 bytes.
5356 (display_mode_element): Don't assume strlen fits in int.
5357
5358 * termcap.c: Don't assume sizes fit in int and never overflow.
5359 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
5360 (gobble_line): Check for size-calculation overflow.
5361
5362 * minibuf.c (Fread_buffer):
5363 * lread.c (intern, intern_c_string):
5364 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
5365 Don't assume string length fits in int.
5366
5367 * keyboard.c (parse_tool_bar_item):
5368 * gtkutil.c (style_changed_cb): Avoid need for strlen.
5369
5370 * font.c: Don't assume string length fits in int.

5375 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
5376
5377 * filelock.c: Fix some buffer overrun and integer overflow issues.
5378 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
5379 Reformulate so as not to need the command string.
5380 Invoke gzip -cd rather than gunzip, as it's more portable.
5381 (lock_info_type, lock_file_1, lock_file):
5382 Don't assume pid_t and time_t fit in unsigned long.
5383 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
5384 (current_lock_owner): Prefer signed type for sizes.
5385 Use memcpy, not strncpy, where memcpy is what is really wanted.
5386 Don't assume (via atoi) that time_t and pid_t fit in int.
5387 Check for time_t and/or pid_t out of range, e.g., via a network share.
5388 Don't alloca where an auto var works fine.
5389
5390 * fileio.c: Fix some integer overflow issues.
5391 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
5392 Don't assume string length fits in int.
5393 (directory_file_name): Don't assume string length fits in long.
5394 (make_temp_name): Don't assume pid fits in int, or that its print
5395 length is less than 20.
5396
5397 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
5398
5399 * coding.c (make_subsidiaries): Don't assume string length fits in int.
5400
5401 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
5402
5403 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
5404 We prefer signed integers, even for size calculations.
5405
5406 * emacs.c: Don't assume string length fits in 'int'.
5407 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
5408 (main): Don't invoke strlen when not needed.
5409
5410 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
5411 (XD_DEBUG_MESSAGE): Don't waste a byte.
5412
5413 * callproc.c (getenv_internal_1, getenv_internal)
5414 (Fgetenv_internal):
5415 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
5416
5417 * lread.c (invalid_syntax): Omit length argument.
5418 All uses changed. This doesn't fix a bug, but it simplifies the
5419 code away from its former Hollerith-constant appearance, and it's
5420 one less 'int' to worry about when looking at integer-overflow issues.
5421 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
5422
5423 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
5424 This didn't break anything, but it didn't help either.
5425 It's confusing to put a bogus integer in a place where the actual
5426 value does not matter.
5427 (LIST_END_P): Remove unused macro and its bogus comment.
5428 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
5429
5430 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
5431 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
5432 implementation.
5433 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
5434 We prefer signed types, and the value cannot exceed the EMACS_INT
5435 range anyway (because otherwise the length would not be representable).
5436 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
5437 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
5438 This avoids a GCC warning when WIDE_EMACS_INT.
5439
5440 * indent.c (sane_tab_width): New function.
5441 (current_column, scan_for_column, Findent_to, position_indentation)
5442 (compute_motion): Use it. This is just for clarity.
5443 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
5444
5445 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
5446
5447 * lisp.h (lint_assume): New macro.
5448 * composite.c (composition_gstring_put_cache):
5449 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
5450
5451 * editfns.c, insdel.c:
5452 Omit unnecessary forward decls, to simplify future changes.
5453
5454 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
5455
5456 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
5457
5458 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
5459 Use much-faster test for byte-length change.
5460 Don't assume string byte-length fits in 'int'.
5461 Check that character arg fits in 'int'.
5462 (mapcar1): Declare byte as byte, for clarity.
5463
5464 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
5465
5466 * fns.c (concat): Catch string overflow earlier.
5467 Do not rely on integer wraparound.
5468
5469 * dispextern.h (struct it.overlay_strings_charpos)
5470 (struct it.selective): Now EMACS_INT, not int.
5471 * xdisp.c (forward_to_next_line_start)
5472 (back_to_previous_visible_line_start)
5473 (reseat_at_next_visible_line_start, next_element_from_buffer):
5474 Don't arbitrarily truncate the value of 'selective' to int.
5475
5476 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
5477
5478 * composite.c: Don't truncate sizes to 'int'.
5479 (composition_gstring_p, composition_reseat_it)
5480 (composition_adjust_point): Use EMACS_INT, not int.
5481 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
5482 not EMACS_UINT, for indexes.
5483
5484 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
5485
5486 * buffer.c: Include <verify.h>.
5487 (struct sortvec.priority, struct sortstr.priority):
5488 Now EMACS_INT, not int.
5489 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
5490 (struct sortstr.size, record_overlay_string)
5491 (struct sortstrlist.size, struct sortlist.used):
5492 Don't truncate size to int.
5493 (record_overlay_string): Check for size-calculation overflow.
5494 (init_buffer_once): Check at compile-time, not run-time.
5495
5496 2011-06-22 Jim Meyering <meyering@redhat.com>
5497
5498 Don't leak an XBM-image-sized buffer
5499 * image.c (xbm_load): Free the image buffer after using it.
5500
5501 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
5502
5503 Port to Sun C.
5504 * composite.c (find_automatic_composition): Omit needless 'return 0;'
5505 that Sun C diagnosed.
5506 * fns.c (secure_hash): Fix pointer signedness issue.
5507 * intervals.c (static_offset_intervals): New function.
5508 (offset_intervals): Use it.
5509
5510 2011-06-21 Leo Liu <sdl.web@gmail.com>
5511
5512 * deps.mk (fns.o):
5513 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
5514 sha512.h.
5515
5516 * fns.c (secure_hash): Rename from crypto_hash_function and change
5517 the first arg to accept symbols.
5518 (Fsecure_hash): New primitive.
5519 (syms_of_fns): New symbols.
5520
5521 2011-06-20 Deniz Dogan <deniz@dogan.se>
5522
5523 * process.c (Fset_process_buffer): Clarify return value in
5524 docstring.
5525
5526 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
5527
5528 * dispnew.c (add_window_display_history): Use BVAR.
5529
5530 * xdisp.c (debug_method_add): Use BVAR.
5531 (check_window_end, dump_glyph_matrix, dump_glyph)
5532 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
5533
5534 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
5535 Likewise.
5536
5537 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
5538 check till after the cache is created in init_frame_faces.
5539
5540 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
5541
5542 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
5543
5544 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
5545
5546 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
5547 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
5548 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
5549
5550 Improve buffer-overflow checking (Bug#8873).
5551 * fileio.c (Finsert_file_contents):
5552 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
5553 Remove the old (too-loose) buffer overflow checks.
5554 They weren't needed, since make_gap checks for buffer overflow.
5555 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
5556 The old code merely checked for Emacs fixnum overflow, and relied
5557 on undefined (wraparound) behavior. The new code avoids undefined
5558 behavior, and also checks for ptrdiff_t and/or size_t overflow.
5559
5560 * editfns.c (Finsert_char): Don't dump core with very negative counts.
5561 Tune. Don't use wider integers than needed. Don't use alloca.
5562 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
5563
5564 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
5565
5566 * insdel.c, lisp.h (buffer_overflow): New function.
5567 (insert_from_buffer_1, replace_range, replace_range_2):
5568 * insdel.c (make_gap_larger):
5569 * editfns.c (Finsert_char):
5570 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
5571
5572 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
5573
5574 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
5575
5576 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
5577
5578 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
5579 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
5580
5581 * fileio.c: Don't assume EMACS_INT fits in off_t.
5582 (emacs_lseek): New static function.
5583 (Finsert_file_contents, Fwrite_region): Use it.
5584 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
5585
5586 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
5587
5588 * fns.c: Don't overflow int when computing a list length.
5589 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
5590 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
5591 truncation on 64-bit hosts. Check for QUIT every
5592 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
5593 faster and is responsive enough.
5594 (Flength): Report an error instead of overflowing an integer.
5595 (Fsafe_length): Return a float if the value is not representable
5596 as a fixnum. This shouldn't happen except in contrived situations.
5597 (Fnthcdr, Fsort): Don't assume list length fits in int.
5598 (Fcopy_sequence): Don't assume vector length fits in int.
5599
5600 * alloc.c: Check that resized vectors' lengths fit in fixnums.
5601 (header_size, word_size): New constants.
5602 (allocate_vectorlike): Don't check size overflow here.
5603 (allocate_vector): Check it here instead, since this is the only
5604 caller of allocate_vectorlike that could cause overflow.
5605 Check that the new vector's length is representable as a fixnum.
5606
5607 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
5608 The previous code was bogus. For example, next_almost_prime (32)
5609 returned 39, which is undesirable as it is a multiple of 3; and
5610 next_almost_prime (24) returned 25, which is a multiple of 5 so
5611 why was the code bothering to check for multiples of 7?
5612
5613 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
5614
5615 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
5616
5617 Variadic C functions now count arguments with ptrdiff_t.
5618 This partly undoes my 2011-03-30 change, which replaced int with size_t.
5619 Back then I didn't know that the Emacs coding style prefers signed int.
5620 Also, in the meantime I found a few more instances where arguments
5621 were being counted with int, which may truncate counts on 64-bit
5622 machines, or EMACS_INT, which may be unnecessarily wide.
5623 * lisp.h (struct Lisp_Subr.function.aMANY)
5624 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
5625 Arg counts are now ptrdiff_t, not size_t.
5626 All variadic functions and their callers changed accordingly.
5627 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
5628 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
5629 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
5630 * callint.c (Fcall_interactively): Check arg count for overflow,
5631 to avoid potential buffer overrun. Use signed char, not 'int',
5632 for 'varies' array, so that we needn't bother to check its size
5633 calculation for overflow.
5634 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
5635 * eval.c (apply_lambda):
5636 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
5637 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
5638 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
5639
5640 * callint.c (Fcall_interactively): Don't use index var as event count.
5641
5642 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
5643 * mem-limits.h (SIZE): Remove; no longer used.
5644
5645 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
5646
5647 Remove unnecessary casts.
5648 * xterm.c (x_term_init):
5649 * xfns.c (x_set_border_pixel):
5650 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
5651 These aren't needed now that we assume ANSI C.
5652
5653 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
5654 It's more likely to cause problems (due to unsigned overflow)
5655 than to cure them.
5656
5657 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
5658
5659 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
5660
5661 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
5662
5663 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
5664
5665 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
5666
5667 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
5668
5669 GLYPH_CODE_FACE returns EMACS_INT, not int.
5670 * dispextern.h (merge_faces):
5671 * xfaces.c (merge_faces):
5672 * xdisp.c (get_next_display_element, next_element_from_display_vector):
5673 Don't assume EMACS_INT fits in int.
5674
5675 * character.h (CHAR_VALID_P): Remove unused parameter.
5676 * fontset.c, lisp.h, xdisp.c: All uses changed.
5677
5678 * editfns.c (Ftranslate_region_internal): Omit redundant test.
5679
5680 * fns.c (concat): Minor tuning based on overflow analysis.
5681 This doesn't fix any bugs. Use int to hold character, instead
5682 of constantly refetching from Emacs object. Use XFASTINT, not
5683 XINT, for value known to be a character. Don't bother comparing
5684 a single byte to 0400, as it's always less.
5685
5686 * floatfns.c (Fexpt):
5687 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
5688
5689 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
5690 for characters.
5691
5692 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
5693
5694 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
5695 Without this fix, on a 64-bit host (aset S 0 4294967386) would
5696 incorrectly succeed when S was a string, because 4294967386 was
5697 truncated before it was used.
5698
5699 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
5700 Otherwise, an out-of-range integer could cause undefined behavior
5701 on a 64-bit host.
5702
5703 * composite.c: Use int, not EMACS_INT, for characters.
5704 (fill_gstring_body, composition_compute_stop_pos): Use int, not
5705 EMACS_INT, for values that are known to be in character range.
5706 This doesn't fix any bugs but is the usual style inside Emacs and
5707 may generate better code on 32-bit machines.
5708
5709 Make sure a 64-bit char is never passed to ENCODE_CHAR.
5710 This is for reasons similar to the recent CHAR_STRING fix.
5711 * charset.c (Fencode_char): Check that character arg is actually
5712 a character. Pass an int to ENCODE_CHAR.
5713 * charset.h (ENCODE_CHAR): Verify that the character argument is no
5714 wider than 'int', as a compile-time check to prevent future regressions
5715 in this area.
5716
5717 * character.c (char_string): Remove unnecessary casts.
5718
5719 Make sure a 64-bit char is never passed to CHAR_STRING.
5720 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
5721 by silently ignoring the top 32 bits, allowing some values
5722 that were far too large to be valid characters.
5723 * character.h: Include <verify.h>.
5724 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
5725 arguments are no wider than unsigned, as a compile-time check
5726 to prevent future regressions in this area.
5727 * data.c (Faset):
5728 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
5729 (Fsubst_char_in_region):
5730 * fns.c (concat):
5731 * xdisp.c (decode_mode_spec_coding):
5732 Adjust to CHAR_STRING's new requirement.
5733 * editfns.c (Finsert_char, Fsubst_char_in_region):
5734 * fns.c (concat): Check that character args are actually
5735 characters. Without this test, these functions did the wrong
5736 thing with wildly out-of-range values on 64-bit hosts.
5737
5738 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
5739 These casts should not be needed on 32-bit hosts, either.
5740 * keyboard.c (read_char):
5741 * lread.c (Fload): Remove casts to unsigned.
5742
5743 * lisp.h (UNSIGNED_CMP): New macro.
5744 This fixes comparison bugs on 64-bit hosts.
5745 (ASCII_CHAR_P): Use it.
5746 * casefiddle.c (casify_object):
5747 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
5748 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
5749 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
5750 * dispextern.h (FACE_FROM_ID):
5751 * keyboard.c (read_char): Use UNSIGNED_CMP.
5752
5753 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
5754 not to EMACS_INT, to avoid GCC warning.
5755
5756 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
5757
5758 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
5759 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
5760 isn't needed on 32-bit machines.
5761
5762 * buffer.c (Fgenerate_new_buffer_name):
5763 Use EMACS_INT for count, not int.
5764 (advance_to_char_boundary): Return EMACS_INT, not int.
5765
5766 * data.c (Qcompiled_function): Now static.
5767
5768 * window.c (window_body_lines): Now static.
5769
5770 * image.c (gif_load): Rename local to avoid shadowing.
5771
5772 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
5773 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
5774 * alloc.c (make_save_value): Integer argument is now of type
5775 ptrdiff_t, not int.
5776 (mark_object): Use ptrdiff_t, not int.
5777 * lisp.h (pD): New macro.
5778 * print.c (print_object): Use it.
5779
5780 * alloc.c: Use EMACS_INT, not int, to count objects.
5781 (total_conses, total_markers, total_symbols, total_vector_size)
5782 (total_free_conses, total_free_markers, total_free_symbols)
5783 (total_free_floats, total_floats, total_free_intervals)
5784 (total_intervals, total_strings, total_free_strings):
5785 Now EMACS_INT, not int. All uses changed.
5786 (Fgarbage_collect): Compute overall total using a double, so that
5787 integer overflow is less likely to be a problem. Check for overflow
5788 when converting back to an integer.
5789 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
5790 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
5791 These were 'int' variables that could overflow on 64-bit hosts;
5792 they were never used, so remove them instead of repairing them.
5793 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
5794 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
5795 Previously, this ceilinged at INT_MAX, but that doesn't work on
5796 64-bit machines.
5797 (allocate_pseudovector): Don't use EMACS_INT when int would do.
5798
5799 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
5800 (allocate_vectorlike): Check for ptrdiff_t overflow.
5801 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
5802 when a (possibly-narrower) signed value would do just as well.
5803 We prefer using signed arithmetic, to avoid comparison confusion.
5804
5805 * alloc.c: Catch some string size overflows that we were missing.
5806 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
5807 for convenience in STRING_BYTES_MAX.
5808 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
5809 The definition here is exact; the one in lisp.h was approximate.
5810 (allocate_string_data): Check for string overflow. This catches
5811 some instances we weren't catching before. Also, it catches
5812 size_t overflow on (unusual) hosts where SIZE_MAX <= min
5813 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
5814 and ptrdiff_t and EMACS_INT are both 64 bits.
5815
5816 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
5817 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
5818 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
5819
5820 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
5821
5822 * alloc.c (Fmake_string): Check for out-of-range init.
5823
5824 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
5825
5826 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
5827
5828 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
5829
5830 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
5831 xg_get_default_scrollbar_width.
5832
5833 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
5834 (int_gtk_range_get_value): Move to the scroll bar part of the file.
5835 (style_changed_cb): Call update_theme_scrollbar_width and call
5836 x_set_scroll_bar_default_width and xg_frame_set_char_size for
5837 all frames (Bug#8505).
5838 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
5839 Call gtk_window_set_resizable if HAVE_GTK3.
5840 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
5841 and height if HAVE_GTK3 (Bug#8505).
5842 (scroll_bar_width_for_theme): New variable.
5843 (update_theme_scrollbar_width): New function.
5844 (xg_get_default_scrollbar_width): Move code to
5845 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
5846 (xg_initialize): Call update_theme_scrollbar_width.
5847
5848 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
5849
5850 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
5851
5852 2011-06-12 Martin Rudalics <rudalics@gmx.at>
5853
5854 * frame.c (make_frame): Call other_buffer_safely instead of
5855 other_buffer.
5856
5857 * window.c (temp_output_buffer_show): Call display_buffer with
5858 second argument Vtemp_buffer_show_specifiers and reset latter
5859 immediately after the call.
5860 (Vtemp_buffer_show_specifiers): New variable.
5861 (auto_window_vscroll_p, next_screen_context_lines)
5862 (Vscroll_preserve_screen_position): Remove leading asterisks from
5863 doc-strings.
5864
5865 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
5866
5867 Fix minor problems found by GCC 4.6.0 static checking.
5868 * buffer.c (Qclone_number): Remove for now, as it's unused.
5869 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
5870 (record_buffer): Remove unused local.
5871 * frame.c (other_visible_frames, frame_buffer_list): Now static.
5872 (set_frame_buffer_list): Remove; unused.
5873 * frame.h (other_visible_frames): Remove decl.

6320 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
6321
6322 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
6323 Do not assume that spare memory exists; that assumption is valid
6324 only if SYSTEM_MALLOC.
6325 (LARGE_REQUEST): New macro, so that the issue of large requests
6326 is separated from the issue of spare memory.
6327
6328 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
6329
6330 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

6356 New error handlers.
6357 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
6358 Obey Vx_select_enable_clipboard_manager. Catch errors in
6359 x_clipboard_manager_save (Bug#8779).
6360 (Vx_select_enable_clipboard_manager): New variable.
6361 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
6362
6363 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
6364
6365 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.

6374 * bidi.c (bidi_level_of_next_char): Fix last change.
6375
6376 2011-06-03 Eli Zaretskii <eliz@gnu.org>
6377

6379
6380 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
6381 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
6382 (bidi_cache_search, bidi_cache_iterator_state)
6383 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
6384 (bidi_level_of_next_char, bidi_move_to_visually_next):
6385 Support character positions inside a run of characters covered by a
6386 display string.
6387 (bidi_paragraph_init, bidi_resolve_explicit_1)
6388 (bidi_level_of_next_char): Call bidi_fetch_char and
6389 bidi_fetch_char_advance instead of FETCH_CHAR and
6390 FETCH_CHAR_ADVANCE.
6391 (bidi_init_it): Initialize new members.
6392 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
6393 definitions.
6394 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
6395 instead of using explicit *_CHAR codes.
6396 (bidi_resolve_explicit, bidi_resolve_weak):
6397 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
6398 bidirectional text is supported only in multibyte buffers.
6399 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
6400 it to initialize the frame_window_p member of struct bidi_it.
6401 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
6402 (bidi_resolve_explicit, bidi_resolve_weak)
6403 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
6404 bidi_it->nchars is non-positive.
6405 (bidi_level_of_next_char): Don't try to lookup the cache for the
6406 next/previous character if nothing is cached there yet, or if we
6407 were just reseat()'ed to a new position.
6408
6409 * xdisp.c (set_cursor_from_row): Set start and stop points
6410 according to the row's direction when priming the loop that looks
6411 for the glyph on which to display cursor.
6412 (single_display_spec_intangible_p): Function deleted.
6413 (display_prop_intangible_p): Reimplement to call
6414 handle_display_spec instead of single_display_spec_intangible_p.
6415 Accept 3 additional arguments needed by handle_display_spec.
6416 This fixes incorrect cursor motion across display property with complex
6417 values: lists, `(when COND...)' forms, etc.
6418 (single_display_spec_string_p): Support property values that are
6419 lists with the argument STRING its top-level element.
6420 (display_prop_string_p): Fix the condition for processing a
6421 property that is a list to be consistent with handle_display_spec.
6422 (handle_display_spec): New function, refactored from the
6423 last portion of handle_display_prop.
6424 (compute_display_string_pos): Accept additional argument
6425 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
6426 value of a `display' property is a "replacing spec".
6427 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
6428 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
6429 the display property, but just return a value indicating whether
6430 the display property will replace the characters it covers.
6431 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
6432 frame_window_p members of struct bidi_it.
6433 (compute_display_string_pos, compute_display_string_end):
6434 New functions.
6435 (push_it): Accept second argument POSITION, where pop_it should
6436 jump to continue iteration.
6437 (reseat_1): Initialize bidi_it.disp_pos.
6438
6439 * keyboard.c (adjust_point_for_property): Adjust the call to
6440 display_prop_intangible_p to its new signature.
6441
6442 * dispextern.h (struct bidi_it): New member frame_window_p.
6443 (bidi_init_it): Update prototypes.
6444 (display_prop_intangible_p): Update prototype.
6445 (compute_display_string_pos, compute_display_string_end):
6446 Declare prototypes.
6447 (struct bidi_it): New members nchars and disp_pos. ch_len is now
6448 EMACS_INT.

6454 * lisp.h: Change signatures accordingly.
6455 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
6456 All callers changed. (Bug#8762)
6457
6458 * gnutls.c: Use Emacs's memory allocators.
6459 Without this change, the gnutls library would invoke malloc etc.
6460 directly, which causes problems on non-SYNC_INPUT hosts, and which
6461 runs afoul of improving memory_full behavior. (Bug#8761)
6462 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
6463 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
6464 xfree instead of the default malloc, realloc, free.
6465 (Fgnutls_boot): No need to check for memory allocation failure,
6466 since xmalloc does that for us.
6467
6468 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
6469 * category.c (hash_get_category_set):
6470 * ccl.c (ccl_driver):
6471 * charset.c (Fdefine_charset_internal):
6472 * charset.h (struct charset.hash_index):

6474 (composition_gstring_put_cache):
6475 * composite.h (struct composition.hash_index):
6476 * dispextern.h (struct image.hash):

6478 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
6479 (hashfn_equal, hashfn_user_defined, make_hash_table)
6480 (maybe_resize_hash_table, hash_lookup, hash_put)
6481 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
6482 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
6483 (Fsxhash, Fgethash, Fputhash, Fmaphash):
6484 * image.c (make_image, search_image_cache, lookup_image)
6485 (xpm_put_color_table_h):
6486 * lisp.h (struct Lisp_Hash_Table):
6487 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
6488 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
6489 for hashes and hash indexes, instead of 'unsigned' and 'int'.
6490 * alloc.c (allocate_vectorlike):
6491 Check for overflow in vector size calculations.
6492 * ccl.c (ccl_driver):
6493 Check for overflow when converting EMACS_INT to int.
6494 * fns.c, image.c: Remove unnecessary static decls that would otherwise
6495 need to be updated by these changes.
6496 * fns.c (make_hash_table, maybe_resize_hash_table):
6497 Check for integer overflow with large hash tables.
6498 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
6499 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
6500 (SXHASH_REDUCE): New macro.
6501 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
6502 Use it instead of discarding useful hash info with large hash values.
6503 (sxhash_float): New function.
6504 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
6505 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
6506 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
6507 Rewrite to use FIXNUM_BITS, as this simplifies things.
6508 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
6509 Adjust signatures to match updated version of code.
6510 (consing_since_gc): Now EMACS_INT, since a single hash table can
6511 use more than INT_MAX bytes.
6512
6513 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
6514
6515 Make it possible to build with GCC-4.6+ -O2 -flto.
6516
6517 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
6518
6519 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
6520
6521 * minibuf.c (get_minibuffer, read_minibuf_unwind):
6522 Call minibuffer-inactive-mode.
6523
6524 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
6525
6526 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
6527 Update dependencies.
6528
6529 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
6530
6531 * data.c (init_data): Remove code for UTS, this system is not
6532 supported anymore.
6533
6534 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
6535
6536 Don't force ./temacs to start in terminal mode.
6537
6538 * frame.c (make_initial_frame): Initialize faces in all cases, not
6539 only when CANNOT_DUMP is defined.
6540 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
6541
6542 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
6543
6544 * dispnew.c (add_window_display_history): Use const for the string
6545 pointer. Remove declaration, not needed.
6546
6547 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
6548
6549 Use 'inline', not 'INLINE'.
6550 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
6551 * alloc.c, fontset.c (INLINE): Remove.
6552 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
6553 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
6554 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
6555 * gmalloc.c (register_heapinfo): Use inline unconditionally.
6556 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
6557
6558 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
6559
6560 Make it possible to run ./temacs.
6561
6562 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
6563 syms_of_callproc does the same thing. Remove test for
6564 "initialized", do it in the caller.
6565 * emacs.c (main): Avoid calling set_initial_environment when dumping.
6566
6567 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
6568
6569 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
6570 (read_minibuf): Use get_minibuffer.
6571 (syms_of_minibuf): Use DEFSYM.
6572 (Qmetadata): New var.
6573 * data.c (Qbuffer): Don't make it static.
6574 (syms_of_data): Use DEFSYM.
6575
6576 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
6577
6578 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
6579 (CCL_CODE_MIN): New macro.
6580
6581 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
6582
6583 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
6584
6585 * eval.c (Qdebug): Now static.
6586 * lisp.h (Qdebug): Remove decl. This reverts a part of the
6587 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
6588 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
6589
6590 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
6591
6592 * image.c: Various fixes to ImageMagick code comments.
6593 (Fimagemagick_types): Doc fix.
6594
6595 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
6596
6597 Minor fixes prompted by GCC 4.6.0 warnings.
6598
6599 * xselect.c (converted_selections, conversion_fail_tag): Now static.
6600
6601 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
6602 (x_clipboard_manager_save_all): Move extern decl to ...
6603 * xterm.h: ... here, so that it can be checked for consistency.
6604
6605 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
6606
6607 * xselect.c (x_clipboard_manager_save_frame)
6608 (x_clipboard_manager_save_all): New functions.
6609 (Fx_clipboard_manager_save): Lisp function deleted.
6610
6611 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.

6619 exiting (Bug#8239).
6620
6621 2011-05-28 Jim Meyering <meyering@redhat.com>
6622
6623 Avoid a sign-extension bug in crypto_hash_function.
6624 * fns.c (to_uchar): Define.
6625 (crypto_hash_function): Use it to convert some newly-signed
6626 variables to unsigned, to avoid sign-extension bugs. For example,
6627 without this change, (md5 "truc") would evaluate to
6628 45723a2aff78ff4fff7fff1114760e62 rather than the expected
6629 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
6630 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
6631
6632 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
6633
6634 Integer overflow fixes.
6635
6636 * dbusbind.c: Serial number integer overflow fixes.
6637 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
6638 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
6639 to hold a serial number that is too large for a fixnum.
6640 (Fdbus_method_return_internal, Fdbus_method_error_internal):
6641 Check for serial numbers out of range. Decode any serial number
6642 that was so large that it became a float. (Bug#8722)
6643
6644 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
6645 (Fdbus_call_method, Fdbus_call_method_asynchronously):
6646 Use XFASTINT rather than XUINT when numbers are nonnegative.
6647 (xd_append_arg, Fdbus_method_return_internal):
6648 (Fdbus_method_error_internal): Likewise. Also, for unsigned
6649 arguments, check that Lisp number is nonnegative, rather than
6650 silently wrapping negative numbers around. (Bug#8722)
6651 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
6652 (Bug#8722)
6653
6654 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
6655
6656 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
6657
6658 ccl: Add integer overflow checks.
6659 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
6660 (IN_INT_RANGE): New macros.
6661 (ccl_driver): Use them to check for integer overflow when
6662 decoding a CCL program. Many of the new checks are whether XINT (x)
6663 fits in int; it doesn't always, on 64-bit hosts. The new version
6664 doesn't catch all possible integer overflows, but it's an
6665 improvement. (Bug#8719)
6666
6667 * alloc.c (make_event_array): Use XINT, not XUINT.
6668 There's no need for unsigned here.
6669
6670 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
6671 This follows up to the 2011-05-06 change that substituted uintptr_t
6672 for EMACS_INT. This case wasn't caught back then.
6673
6674 Rework Fformat to avoid integer overflow issues.
6675 * editfns.c: Include <float.h> unconditionally, as it's everywhere
6676 now (part of C89). Include <verify.h>.
6677 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
6678 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
6679 (Fformat): Avoid the prepass trying to compute sizes; it was only
6680 approximate and thus did not catch overflow reliably. Instead, walk
6681 through the format just once, formatting and computing sizes as we go,
6682 checking for integer overflow at every step, and allocating a larger
6683 buffer as needed. Keep track separately whether the format is
6684 multibyte. Keep only the most-recently calculated precision, rather
6685 than them all. Record whether each argument has been converted to
6686 string. Use EMACS_INT, not int, for byte and char and arg counts.
6687 Support field widths and precisions larger than INT_MAX. Avoid
6688 sprintf's undefined behavior with conversion specifications such as %#d
6689 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
6690 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
6691 formatting out-of-range floating point numbers with int
6692 formats. (Bug#8668)
6693
6694 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
6695
6696 * data.c: Avoid integer truncation in expressions involving floats.
6697 * data.c: Include <intprops.h>.
6698 (arith_driver): When there's an integer overflow in an expression
6699 involving floating point, convert the integers to floating point
6700 so that the resulting value does not suffer from catastrophic
6701 integer truncation. For example, on a 64-bit host (* 4
6702 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
6703 Do not rely on undefined behavior after integer overflow.
6704
6705 merge count_size_as_multibyte, parse_str_to_multibyte
6706 * character.c, character.h (count_size_as_multibyte):
6707 Rename from parse_str_to_multibyte; all uses changed.
6708 Check for integer overflow.
6709 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
6710 since it's now a duplicate of the other. This is more of
6711 a character than a buffer op, so better that it's in character.c.
6712 * fns.c, print.c: Adjust to above changes.
6713
6714 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
6715
6716 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
6717

6726 (crypto_hash_function): Now static.
6727 Fix pointer signedness problems. Avoid unnecessary initializations.
6728
6729 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
6730

6733 * terminal.c (create_terminal): Initialize it.
6734
6735 * xselect.c: Support for clipboard managers.
6736 (Vselection_alist): Move to termhooks.h as terminal-local var.
6737 (LOCAL_SELECTION): New macro.
6738 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
6739 (symbol_to_x_atom): Remove gratuitous arg.
6740 (x_handle_selection_request, lisp_data_to_selection_data)
6741 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
6742 (x_own_selection, x_get_local_selection, x_convert_selection):
6743 New arg, specifying work frame. Use terminal-local Vselection_alist.
6744 (some_frame_on_display): Delete unused function.
6745 (Fx_own_selection_internal, Fx_get_selection_internal)
6746 (Fx_disown_selection_internal, Fx_selection_owner_p)
6747 (Fx_selection_exists_p): New optional frame arg.
6748 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
6749 (x_handle_selection_clear): Don't treat other terminals with the
6750 same keyboard specially. Use the terminal-local Vselection_alist.
6751 (x_clear_frame_selections): Use Frun_hook_with_args.
6752
6753 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
6754
6755 * xterm.h: Add support for those atoms.
6756
6757 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
6758
6759 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
6760 (converted_selections, conversion_fail_tag): New global variables.
6761 (x_selection_request_lisp_error): Free the above.
6762 (x_get_local_selection): Remove unnecessary code.
6763 (x_reply_selection_request): Args changed; handle arbitrary array
6764 of converted selections stored in converted_selections.
6765 Separate the XChangeProperty and SelectionNotify steps.
6766 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
6767 (x_convert_selection): New function.
6768 (x_handle_selection_event): Simplify.
6769 (x_get_foreign_selection): Don't ignore incoming requests while
6770 waiting for an answer; this will fail when we implement
6771 SAVE_TARGETS, and seems unnecessary anyway.
6772 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
6773 (Vx_sent_selection_functions): Doc fix.
6774
6775 2011-05-26 Leo Liu <sdl.web@gmail.com>
6776
6777 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
6778
6779 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6780
6781 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
6782
6783 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
6784 for fringe update if it has periodic bitmap.
6785 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
6786 and fringe_bitmap_periodic_p.
6787
6788 * fringe.c (get_fringe_bitmap_data): New function.
6789 (draw_fringe_bitmap_1, update_window_fringes): Use it.
6790 (update_window_fringes): Record periodicity of fringe bitmap in glyph
6791 row. Mark glyph row for fringe update if periodicity changed.
6792
6793 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
6794 for fringe update unless it has periodic bitmap.
6795
6796 2011-05-25 Kenichi Handa <handa@m17n.org>
6797
6798 * xdisp.c (get_next_display_element): Set correct it->face_id for
6799 a static composition.
6800
6801 2011-05-24 Leo Liu <sdl.web@gmail.com>
6802
6803 * deps.mk (fns.o):
6804 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
6805
6806 * fns.c (crypto_hash_function, Fsha1): New function.
6807 (Fmd5): Use crypto_hash_function.
6808 (syms_of_fns): Add Ssha1.
6809
6810 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
6811
6812 * gnutls.c: Remove unused macros.
6813 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
6814 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
6815 Remove macros that are defined and never used.
6816 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
6817
6818 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
6819
6820 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
6821 (Fx_get_selection_internal): Minor cleanup.
6822 (Fx_own_selection_internal): Rename arguments for consistency with
6823 select.el.
6824
6825 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
6826
6827 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
6828
6829 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
6830
6831 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
6832
6833 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6834
6835 * dispnew.c (scrolling_window): Don't exclude the case that the
6836 last enabled row in the desired matrix touches the bottom boundary.
6837
6838 2011-05-21 Glenn Morris <rgm@gnu.org>
6839
6840 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
6841 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
6842 and add some more files.
6843
6844 2011-05-20 Eli Zaretskii <eliz@gnu.org>
6845
6846 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
6847 report_file_error introduced by the change from 2011-05-07.
6848
6849 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
6850
6851 * systime.h (Time): Define only if emacs is defined.
6852 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
6853 where the include path doesn't have X11/X.h by default. See
6854 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
6855
6856 2011-05-20 Kenichi Handa <handa@m17n.org>
6857
6858 * composite.c (find_automatic_composition): Fix previous change.
6859
6860 2011-05-20 Glenn Morris <rgm@gnu.org>
6861
6862 * lisp.mk: New file, split from Makefile.in.
6863 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
6864 (shortlisp): Remove.
6865 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
6866
6867 2011-05-19 Glenn Morris <rgm@gnu.org>
6868
6869 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
6870 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
6871 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
6872 (lisp): Set the order to that of loadup.el.
6873 (shortlisp): Make it a copy of $lisp.
6874 (SOME_MACHINE_LISP): Remove.
6875 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
6876 Use just $shortlisp, not $SOME_MACHINE_LISP too.
6877
6878 2011-05-18 Kenichi Handa <handa@m17n.org>
6879
6880 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
6881 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
6882 (find_automatic_composition): Mostly rewrite for efficiency.
6883
6884 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
6885
6886 * makefile.w32-in: Update dependencies.
6887
6888 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
6889
6890 * menu.c: Include limits.h (fixes the MS-Windows build broken by
6891 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
6892
6893 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
6894
6895 Fix some integer overflow issues, such as string length overflow.
6896
6897 * insdel.c (count_size_as_multibyte): Check for string overflow.
6898
6899 * character.c (lisp_string_width): Check for string overflow.
6900 Use EMACS_INT, not int, for string indexes and lengths; in
6901 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
6902 the resulting string length overflows an EMACS_INT; instead,
6903 report a string overflow if no precision given. When checking for
6904 precision exhaustion, use a check that cannot possibly have
6905 integer overflow. (Bug#8675)
6906 * character.h (lisp_string_width): Adjust to new signature.
6907
6908 * alloc.c (string_overflow): New function.
6909 (Fmake_string): Use it. This doesn't change behavior, but saves
6910 a few bytes and will simplify future changes.
6911 * character.c (string_escape_byte8): Likewise.
6912 * lisp.h (string_overflow): New decl.
6913
6914 Fixups, following up to the user-interface timestamp change.
6915 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
6916 for UI timestamps, instead of unsigned long.
6917 * msdos.c (mouse_get_pos): Likewise.
6918 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
6919 * w32gui.h (Time): Define by including "systime.h" rather than by
6920 declaring it ourselves. (Bug#8664)
6921
6922 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
6923 * image.c (clear_image_cache): Likewise.
6924
6925 * term.c (term_mouse_position): Don't assume time_t wraparound.
6926
6927 Be more systematic about user-interface timestamps.
6928 Before, the code sometimes used 'Time', sometimes 'unsigned long',
6929 and sometimes 'EMACS_UINT', to represent these timestamps.
6930 This change causes it to use 'Time' uniformly, as that's what X uses.
6931 This makes the code easier to follow, and makes it easier to catch
6932 integer overflow bugs such as Bug#8664.
6933 * frame.c (Fmouse_position, Fmouse_pixel_position):
6934 Use Time, not unsigned long, for user-interface timestamps.
6935 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
6936 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
6937 * keyboard.h (last_event_timestamp): Likewise.
6938 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
6939 * menu.h (xmenu_show): Likewise.
6940 * term.c (term_mouse_position): Likewise.
6941 * termhooks.h (struct input_event.timestamp): Likewise.
6942 (struct terminal.mouse_position_hook): Likewise.
6943 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
6944 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
6945 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
6946 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
6947 what it was before.
6948 * menu.h, termhooks.h: Include "systime.h", for Time.
6949
6950 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
6951 Don't assume that the difference between two unsigned long values
6952 can fit into an integer. At this point, we know button_down_time
6953 <= event->timestamp, so the difference must be nonnegative, so
6954 there's no need to cast the result if double-click-time is
6955 nonnegative, as it should be; check that it's nonnegative, just in
6956 case. This bug is triggered when events are more than 2**31 ms
6957 apart (about 25 days). (Bug#8664)
6958
6959 * xselect.c (last_event_timestamp): Remove duplicate decl.
6960 (x_own_selection): Remove needless cast to unsigned long.
6961
6962 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
6963 that always fit in int. Use a sentinel instead of a counter, to
6964 avoid a temp and to allay GCC's concerns about possible int overflow.
6965 * frame.h (struct frame): Use int for menu_bar_items_used
6966 instead of EMACS_INT, since it always fits in int.
6967
6968 * menu.c (grow_menu_items): Check for int overflow.
6969
6970 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
6971
6972 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
6973 Before, the code was not consistent. These values cannot exceed
6974 2**31 - 1 so there's no need to make them unsigned.
6975 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
6976 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
6977 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
6978 as modifiers.
6979 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
6980
6981 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
6982 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
6983 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
6984 presumably because the widths might not match.
6985
6986 * window.c (size_window): Avoid needless test at loop start.
6987
6988 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
6989
6990 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
6991
6992 2011-05-12 Drew Adams <drew.adams@oracle.com>
6993
6994 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
6995
6996 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6997
6998 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
6999 `width' to `bar_area_x' and `bar_area_width', respectively.
7000 (x_scroll_run): Take account of fringe background extension.
7001
7002 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
7003 Rename local vars `left' and `width' to `bar_area_x' and
7004 `bar_area_width', respectively.
7005 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
7006 background extension.
7007
7008 2011-05-10 Jim Meyering <meyering@redhat.com>
7009
7010 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
7011
7012 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
7013
7014 * image.c (Finit_image_library): Return t for built-in image types,
7015 like pbm and xbm. (Bug#8640)
7016
7017 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
7018
7019 * w32menu.c (set_frame_menubar): Fix submenu allocation.
7020
7021 2011-05-07 Eli Zaretskii <eliz@gnu.org>
7022
7023 * w32console.c (Fset_screen_color): Doc fix.
7024 (Fget_screen_color): New function.
7025 (syms_of_ntterm): Defsubr it.
7026
7027 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
7028 unlink the temporary file if Fcall_process didn't create it in the
7029 first place.
7030 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
7031 child process will be redirected to a file specified with `:file'.
7032 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
7033 cue to call_process_cleanup not to close that handle.
7034
7035 2011-05-07 Ben Key <bkey76@gmail.com>
7036
7037 * makefile.w32-in: The bootstrap-temacs rule now makes use of
7038 one of two shell specific rules, either bootstrap-temacs-CMD or
7039 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
7040 to the previous implementation of the bootstrap-temacs rule.
7041 The bootstrap-temacs-CMD rule is similar to the previous
7042 implementation of the bootstrap-temacs rule except that it
7043 makes use of the ESC_CFLAGS variable instead of the CFLAGS
7044 variable.
7045
7046 These changes, along with some changes to nt/configure.bat,
7047 nt/gmake.defs, and nt/nmake.defs, are required to extend my
7048 earlier fix to add support for --cflags and --ldflags options
7049 that include quotes so that it works whether make uses cmd or
7050 sh as the shell.
7051
7052 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
7053
7054 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
7055 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
7056 is a constant.
7057 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
7058 a string. Handle both cases.
7059 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
7060 (Fdbus_register_method): Use Qinvalid_function.
7061
7062 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
7063
7064 * makefile.w32-in: Update dependencies.
7065 (LISP_H): Add inttypes.h and stdin.h.
7066 (PROCESS_H): Add unistd.h.
7067
7068 2011-05-06 Eli Zaretskii <eliz@gnu.org>
7069
7070 * lread.c: Include limits.h (fixes the MS-Windows build broken by
7071 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
7072
7073 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
7074
7075 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
7076
7077 * term.c (vfatal): Remove stray call to va_end.
7078 It's not needed and the C Standard doesn't allow it here anyway.
7079
7080 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
7081 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
7082
7083 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
7084 bytes.
7085
7086 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
7087
7088 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
7089
7090 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
7091
7092 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
7093
7094 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
7095
7096 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
7097 * charset.c (Fdefine_charset_internal): Don't initialize
7098 charset.code_space[15]. The value was garbage, on hosts with
7099 32-bit int (Bug#8600).
7100
7101 * lread.c (read_integer): Be more consistent with string-to-number.
7102 Use string_to_number to do the actual conversion; this avoids
7103 rounding errors and fixes some other screwups. Without this fix,
7104 for example, #x1fffffffffffffff was misread as -2305843009213693952.
7105 (digit_to_number): Move earlier, for benefit of read_integer.
7106 Return -1 if the digit is out of range for the base, -2 if it is
7107 not a digit in any supported base. (Bug#8602)
7108
7109 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
7110
7111 * dispnew.c (scrolling_window): Return 1 if we scrolled,
7112 to match comment at start of function. This also removes a
7113 GCC warning about overflow in a 32+64-bit port.
7114
7115 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
7116
7117 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
7118 Reported by Stefan Monnier in
7119 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
7120 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
7121 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
7122
7123 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
7124 (EMACS_UINTPTR): Likewise, with uintptr_t.
7125
7126 * lisp.h: Prefer 64-bit EMACS_INT if available.
7127 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
7128 on 32-bit hosts that have 64-bit int, so that they can access
7129 large files.
7130 However, temporarily disable this change unless the temporary
7131 symbol WIDE_EMACS_INT is defined.
7132
7133 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
7134
7135 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
7136 This removes an assumption that EMACS_INT and long are the same
7137 width as pointers. The assumption is true for Emacs porting targets
7138 now, but we want to make other targets possible.
7139 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
7140 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
7141 In the rest of the code, change types of integers that hold casted
7142 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
7143 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
7144 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
7145 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
7146 No need to cast type when ORing.
7147 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
7148 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
7149 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
7150 assume EMACS_INT is the same width as char *.
7151 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
7152 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
7153 Remove no-longer-needed casts.
7154 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
7155 (xg_tool_bar_help_callback, xg_make_tool_item):
7156 Use EMACS_INTPTR to hold an integer
7157 that will be cast to void *; this can avoid a GCC warning
7158 if EMACS_INT is not the same width as void *.
7159 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
7160 * xdisp.c (display_echo_area_1, resize_mini_window_1):
7161 (current_message_1, set_message_1):
7162 Use a local to convert to proper width without a cast.
7163 * xmenu.c (dialog_selection_callback): Likewise.
7164
7165 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
7166 Also, don't assume VALBITS / RAND_BITS is less than 5,
7167 and don't rely on undefined behavior when shifting a 1 left into
7168 the sign bit.
7169 * lisp.h (get_random): Change signature to match.
7170
7171 * lread.c (hash_string): Use size_t, not int, for hash computation.
7172 Normally we prefer signed values; but hashing is special, because
7173 it's better to use unsigned division on hash table sizes so that
7174 the remainder is nonnegative. Also, size_t is the natural width
7175 for hashing into memory. The previous code used 'int', which doesn't
7176 retain enough info to hash well into very large tables.
7177 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
7178
7179 * dbusbind.c: Don't possibly lose pointer info when converting.
7180 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
7181 Use XPNTR rather than XHASH, so that the high-order bits of
7182 the pointer aren't lost when converting through void *.
7183
7184 * eval.c (Fautoload): Don't double-shift a pointer.
7185
7186 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
7187

7220 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
7221 Remove unused parameter `fildes'.
7222 * process.c (read_process_output, send_process): Don't pass it.
7223

7226 Fix previous change: the library cache is defined in w32.c.
7227 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
7228 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

7265 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
7266 Initialize and staticpro them.
7267 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
7268
7269 * process.c: Include lisp.h before w32.h, not after.
7270 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
7271 instead of gnutls_record_check_pending.
7272

7314 interruptions.
7315
7316 * callproc.c (Fcall_process): Add (:file "file") as an option for
7317 the STDOUT buffer.

7323 rather than `XVECTOR (FOO)->size'.
7324
7325 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
7326 inttypes.h, as a gnulib replacement is used if it not available in
7327 system headers.

7336 will grow beyond MOST_POSITIVE_FIXNUM.
7337 (decode_coding_emacs_mule): Abort if there isn't enough place in
7338 charbuf for the composition carryover bytes. Reserve an extra
7339 space for up to 2 characters produced in a loop.
7340 (decode_coding_iso_2022): Abort if there isn't enough place in

7350 * window.c (window_scroll_line_based): Use a marker instead of
7351 simple variables to record original value of point. (Bug#7952)
7352

7355
7356 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
7357

7383 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>

7391 2011-04-27 Eli Zaretskii <eliz@gnu.org>
7392
7393 Improve `doprnt' and its usage. (Bug#8545)
7394 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
7395 `format_end'. Remove support for %l as a conversion specifier.
7396 Don't use xrealloc. Improve diagnostics when the %l size modifier
7397 is used. Update the commentary.
7398
7399 * eval.c (verror): Simplify calculation of size_t.
7400
7401 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
7402 messages.
7403
7404 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
7405
7406 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
7407 change.
7408
7409 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
7410
7411 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
7412 This makes this file independent of the recent pseudovector change.
7413
7414 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
7415
7416 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
7417
7418 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
7419 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
7420 Remove unused local.
7421 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
7422
7423 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
7424 GCC 4.6.0 optimizes based on type-based alias analysis.
7425 For example, if b is of type struct buffer * and v of type struct
7426 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
7427 != &v->size, and therefore "v->size = 1; b->size = 2; return
7428 v->size;" must therefore return 1. This assumption is incorrect
7429 for Emacs, since it type-puns struct Lisp_Vector * with many other
7430 types. To fix this problem, this patch adds a new type struct
7431 vectorlike_header that documents the constraints on layout of vectors
7432 and pseudovectors, and helps optimizing compilers not get fooled
7433 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
7434 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
7435 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
7436 the size member.
7437 (XSETPVECTYPE): Rewrite in terms of new macro.
7438 (XSETPVECTYPESIZE): New macro, specifying both type and size.
7439 This is a bit clearer, and further avoids the possibility of
7440 undesirable aliasing.
7441 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
7442 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
7443 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
7444 since Lisp_Subr is a special case (no "next" field).
7445 (ASIZE): Now uses header.size rather than size.
7446 All previous uses of XVECTOR (foo)->size replaced to use this macro,
7447 to avoid the hassle of writing XVECTOR (foo)->header.size.
7448 (struct vectorlike_header): New type.
7449 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
7450 object, to help avoid aliasing.
7451 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
7452 (SUBRP): Likewise, since Lisp_Subr is a special case.
7453 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
7454 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
7455 (struct Lisp_Hash_Table): Combine first two members into a single
7456 struct vectorlike_header member. All uses of "size" and "next" members
7457 changed to be "header.size" and "header.next".
7458 * buffer.h (struct buffer): Likewise.
7459 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
7460 * frame.h (struct frame): Likewise.
7461 * process.h (struct Lisp_Process): Likewise.
7462 * termhooks.h (struct terminal): Likewise.
7463 * window.c (struct save_window_data, struct saved_window): Likewise.
7464 * window.h (struct window): Likewise.
7465 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
7466 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
7467 * buffer.c (init_buffer_once): Likewise.
7468 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
7469 special case.
7470 * process.c (Fformat_network_address): Use local var for size,
7471 for brevity.
7472
7473 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
7474
7475 Make the Lisp reader and string-to-float more consistent (Bug#8525)
7476 * data.c (atof): Remove decl; no longer used or needed.
7477 (digit_to_number): Move to lread.c.
7478 (Fstring_to_number): Use new string_to_number function, to be
7479 consistent with how the Lisp reader treats infinities and NaNs.
7480 Do not assume that floating-point numbers represent EMACS_INT
7481 without losing information; this is not true on most 64-bit hosts.
7482 Avoid double-rounding errors, by insisting on integers when
7483 parsing non-base-10 numbers, as the documentation specifies.
7484 * lisp.h (string_to_number): New decl, replacing ...
7485 (isfloat_string): Remove.
7486 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
7487 (read1): Do not accept +. and -. as integers; this
7488 appears to have been a coding error. Similarly, do not accept
7489 strings like +-1e0 as floating point numbers. Do not report
7490 overflow for integer overflows unless the base is not 10 which
7491 means we have no simple and reliable way to continue.
7492 Break out the floating-point parsing into a new
7493 function string_to_number, so that Fstring_to_number parses
7494 floating point numbers consistently with the Lisp reader.
7495 (digit_to_number): Move here from data.c. Make it static inline.
7496 (E_CHAR, EXP_INT): Remove, replacing with ...
7497 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
7498 (string_to_number): New function, replacing isfloat_string.
7499 This function checks for valid syntax and produces the resulting
7500 Lisp float number too. Rework it so that string-to-number
7501 no longer mishandles examples like "1.0e+". Use strtoumax,
7502 so that overflow for non-base-10 numbers is reported only when
7503 there's no portable and simple way to convert to floating point.
7504
7505 * textprop.c (set_text_properties_1): Rewrite for clarity,
7506 and to avoid GCC warning about integer overflow.
7507
7508 * intervals.h (struct interval): Use EMACS_INT for members
7509 where EMACS_UINT might cause problems. See
7510 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
7511 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
7512 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
7513 All uses changed.
7514 (offset_intervals): Tell GCC not to worry about length overflow
7515 when negating a negative length.
7516
7517 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
7518 (overrun_check_free): Likewise.
7519
7520 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
7521 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
7522 word size.
7523
7524 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
7525 (gnutls_make_error): Rename local to avoid shadowing.
7526 (gnutls_emacs_global_deinit): ifdef out; not used.

7529
7530 * lread.c (openp): Don't stuff size_t into an 'int'.
7531 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
7532 about possible signed overflow.
7533
7534 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
7535 (GDK_KEY_g): Don't define if already defined.

7538
7539 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
7540 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
7541
7542 * xfns.c (Fx_window_property): Simplify a bit,
7543 to make a bit faster and to avoid GCC 4.6.0 warning.
7544 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
7545
7546 * fns.c (internal_equal): Don't assume size_t fits in int.
7547
7548 * alloc.c (compact_small_strings): Tighten assertion a little.
7549
7550 Replace pEd with more-general pI, and fix some printf arg casts.
7551 * lisp.h (pI): New macro, generalizing old pEd macro to other
7552 conversion specifiers. For example, use "...%"pI"d..." rather
7553 than "...%"pEd"...".
7554 (pEd): Remove. All uses replaced with similar uses of pI.
7555 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
7556 * alloc.c (check_pure_size): Don't overflow by converting size to int.
7557 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
7558 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.

7562 64-bit hosts.
7563 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
7564 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
7565 * print.c (safe_debug_print, print_object): Likewise.
7566 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
7567 to int.
7568 Use pI instead of if-then-else-abort. Use %p to avoid casts,
7569 avoiding the 0 flag, which is not portable.
7570 * process.c (Fmake_network_process): Use pI to avoid cast.
7571 * region-cache.c (pp_cache): Likewise.
7572 * xdisp.c (decode_mode_spec): Likewise.

7576 (x_stop_queuing_selection_requests): Likewise.
7577 (x_get_window_property): Don't truncate byte count to an 'int'
7578 when tracing.
7579
7580 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
7581 here, since it parses constructs like leading '-' and spaces,
7582 which are not wanted; and it overflows with large numbers.
7583 Instead, simply match F[0-9]+, which is what is wanted anyway.
7584
7585 * alloc.c: Remove unportable assumptions about struct layout.
7586 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
7587 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
7588 (allocate_vectorlike, make_pure_vector): Use the new macros,
7589 plus offsetof, to remove unportable assumptions about struct layout.
7590 These assumptions hold on all porting targets that I know of, but
7591 they are not guaranteed, they're easy to remove, and removing them
7592 makes further changes easier.
7593
7594 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
7595 This doesn't fix a bug but makes the code clearer.
7596 (string_overrun_cookie): Now const. Use initializers that
7597 don't formally overflow signed char, to avoid warnings.
7598 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
7599 can cause Emacs to crash when string overrun checking is enabled.
7600 (allocate_buffer): Don't assume sizeof (struct buffer) is a
7601 multiple of sizeof (EMACS_INT); it need not be, if
7602 alignof(EMACS_INT) < sizeof (EMACS_INT).
7603 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
7604
7605 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

7624
7625 * alloc.c (check_sblock, check_string_bytes)

7633
7634 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
7635 "cast to pointer from integer of different size".
7636
7637 Improve doprnt and its use in verror. (Bug#8545)
7638 * doprnt.c (doprnt): Document the set of format control sequences
7639 supported by the function. Use SAFE_ALLOCA instead of always
7640 using `alloca'.
7641
7642 * eval.c (verror): Don't limit the buffer size at size_max-1, that
7643 is one byte too soon. Don't use xrealloc; instead xfree and
7644 xmalloc anew.
7645
7646 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
7647
7648 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
7649 callbacks stage.
7650
7651 * gnutls.c: Renamed global_initialized to
7652 gnutls_global_initialized. Added internals for the
7653 :verify-hostname-error, :verify-error, and :verify-flags
7654 parameters of `gnutls-boot' and documented those parameters in the
7655 docstring. Start callback support.
7656 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
7657 unless a fatal error occurred. Call gnutls_alert_send_appropriate
7658 on error. Return error code.

7730 * doprnt.c: Include limits.h.
7731 (SIZE_MAX): New macro.
7732 (doprnt): Return a size_t value. 2nd arg is now size_t.
7733 Many local variables are now size_t instead of int or unsigned.
7734 Improve overflow protection. Support `l' modifier for integer
7735 conversions. Support %l conversion. Don't assume an EMACS_INT
7736 argument for integer conversions and for %c.
7737
7738 * lisp.h (doprnt): Restore prototype.
7739
7740 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

7753 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
7754
7755 * callint.c (Fcall_interactively): When displaying error message
7756 about invalid control letter, pass the character's codepoint, not

7758 in octal and display also its hex code.
7759
7760 * character.c (char_string): Use %x to display the (unsigned)
7761 codepoint of an invalid character, to avoid displaying a bogus

7962 * nsfont.m: Fixed bugs in ns_get_family and
7963 ns_descriptor_to_entity that were caused by using free to

7966 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
7967 --enable-checking=xmallocoverrun). xfree is now used to
7968 deallocate these memory blocks.

8341 (message_enable_multibyte, free_misc): Remove.
8342 (catchlist, handlerlist, mark_backtrace):
8343 Declare only if BYTE_MARK_STACK.
8344 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
8345 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
8346 (message_enable_multibyte): Remove decl.
8347 (free_misc, interval_free_list, float_block, float_block_index):
8348 (n_float_blocks, float_free_list, cons_block, cons_block_index):
8349 (cons_free_list, last_marked_index):
8350 Now static.
8351 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
8352 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
8353 (mark_backtrace): Define only if BYTE_MARK_STACK.
8354 * xdisp.c (message_enable_multibyte): Now static.
8355
8356 Declare Lisp_Object Q* variables to be 'static' if not exported.
8357 This makes it easier for human readers (and static analyzers)
8358 to see whether these variables are used from other modules.
8359 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
8360 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
8361 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
8362 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:

8364 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
8365 * xmenu.c, xselect.c:
8366 Declare Q* vars static if they are not used in other modules.
8367 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
8368 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
8369 Remove decls of unexported vars.
8370 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
8371
8372 * lisp.h (DEFINE_FUNC): Make sname 'static'.
8373
8374 Make Emacs functions such as Fatom 'static' by default.
8375 This makes it easier for human readers (and static analyzers)
8376 to see whether these functions can be called from other modules.
8377 DEFUN now defines a static function. To make the function external
8378 so that it can be used in other C modules, use the new macro DEFUE.
8379 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
8380 (Finit_image_library):
8381 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
8382 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
8383 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
8384 Remove decls, since these functions are now static.
8385 (Funintern, Fget_internal_run_time): New decls, since these functions
8386 were already external.
8387
8388 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
8389 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
8390 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:

8393 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
8394 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
8395 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
8396 Mark functions with DEFUE instead of DEFUN,
8397 if they are used in other modules.
8398 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
8399 decls for now-static functions.
8400 * buffer.h (Fdelete_overlay): Remove decl.
8401 * callproc.c (Fgetenv_internal): Mark as internal.
8402 * composite.c (Fremove_list_of_text_properties): Remove decl.
8403 (Fcomposition_get_gstring): New forward static decl.
8404 * composite.h (Fcomposite_get_gstring): Remove decl.
8405 * dired.c (Ffile_attributes): New forward static decl.
8406 * doc.c (Fdocumntation_property): New forward static decl.
8407 * eval.c (Ffetch_bytecode): New forward static decl.

8409 * fileio.c (Fmake_symbolic_link): New forward static decl.
8410 * image.c (Finit_image_library): New forward static decl.
8411 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
8412 * intervals.h (Fprevious_property_change):
8413 (Fremove_list_of_text_properties): Remove decls.
8414 * keyboard.c (Fthis_command_keys): Remove decl.
8415 (Fcommand_execute): New forward static decl.
8416 * keymap.c (Flookup_key): New forward static decl.
8417 (Fcopy_keymap): Now static.
8418 * keymap.h (Flookup_key): Remove decl.
8419 * process.c (Fget_process): New forward static decl.
8420 (Fprocess_datagram_address): Mark as internal.
8421 * syntax.c (Fsyntax_table_p): New forward static decl.

8424 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
8425 Now internal.
8426 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
8427 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
8428
8429 * editfns.c (Fformat): Remove unreachable code.
8430
8431 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
8432
8433 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
8434 change. (Bug#8496)
8435
8436 2011-04-13 Eli Zaretskii <eliz@gnu.org>
8437
8438 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
8439 when at ZV. (Bug#8487)
8440
8441 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
8442
8443 * charset.c (Fclear_charset_maps): Use xfree instead of free.
8444 (Bug#8437)
8445 * keyboard.c (parse_tool_bar_item): Likewise.
8446 * sound.c (sound_cleanup, alsa_close): Likewise.
8447 * termcap.c (tgetent): Likewise.
8448 * xfns.c (x_default_font_parameter): Likewise.
8449 * xsettings.c (read_and_apply_settings): Likewise.
8450
8451 * alloc.c (overrun_check_malloc, overrun_check_realloc)
8452 (overrun_check_free): Protoize.
8453
8454 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
8455
8456 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
8457 since callers should never pass a negative size.
8458 Change the signature to match that of plain 'read' and 'write'; see
8459 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
8460 * lisp.h: Update prototypes of emacs_write and emacs_read.
8461
8462 2011-04-11 Eli Zaretskii <eliz@gnu.org>
8463
8464 * xdisp.c (redisplay_window): Don't try to determine the character
8465 position of the scroll margin if the window start point w->startp
8466 is outside the buffer's accessible region. (Bug#8468)
8467
8468 2011-04-10 Eli Zaretskii <eliz@gnu.org>
8469
8470 Fix write-region and its subroutines for buffers > 2GB.
8471 * fileio.c (a_write, e_write): Modify declaration of arguments and
8472 local variables to support buffers larger than 2GB.
8473 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
8474
8475 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
8476 argument, local variables, and return value.
8477
8478 * lisp.h: Update prototypes of emacs_write and emacs_read.
8479
8480 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
8481
8482 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
8483
8484 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
8485
8486 Fix more problems found by GCC 4.6.0's static checks.
8487
8488 * xdisp.c (vmessage): Use a better test for character truncation.
8489
8490 * charset.c (load_charset_map): <, not <=, for optimization,
8491 and to avoid potential problems with integer overflow.
8492 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
8493 * casetab.c (set_identity, shuffle): Likewise.
8494 * editfns.c (Fformat): Likewise.
8495 * syntax.c (skip_chars): Likewise.
8496
8497 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
8498 This also lets GCC 4.6.0 generate slightly better loop code.
8499
8500 * callint.c (Fcall_interactively): <, not <=, for optimization.
8501 (Fcall_interactively): Count the number of arguments produced,
8502 not the number of arguments given. This is simpler and lets GCC
8503 4.6.0 generate slightly better code.
8504
8505 * ftfont.c: Distingish more carefully between FcChar8 and char.
8506 The previous code passed unsigned char * to a functions like
8507 strlen and xstrcasecmp that expect char *, which does not
8508 conform to the C standard.
8509 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
8510 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
8511 char * when the C standard requires it.
8512
8513 * keyboard.c (read_char): Remove unused var.
8514
8515 * eval.c: Port to Windows vsnprintf (Bug#8435).
8516 Include <limits.h>.
8517 (SIZE_MAX): Define if the headers do not.
8518 (verror): Do not give up if vsnprintf returns a negative count.
8519 Instead, grow the buffer. This ports to Windows vsnprintf, which
8520 does not conform to C99. Problem reported by Eli Zaretskii.
8521 Also, simplify the allocation scheme, by avoiding the need for
8522 calling realloc, and removing the ALLOCATED variable.
8523
8524 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
8525
8526 Remove invocations of doprnt, as Emacs now uses vsnprintf.
8527 But keep the doprint source code for now, as we might revamp it
8528 and use it again (Bug#8435).
8529 * lisp.h (doprnt): Remove.
8530 * Makefile.in (base_obj): Remove doprnt.o.
8531 * deps.mk (doprnt.o): Remove.
8532
8533 error: Print 32- and 64-bit integers portably (Bug#8435).
8534 Without this change, on typical 64-bit hosts error ("...%d...", N)
8535 was used to print both 32- and 64-bit integers N, which relied on
8536 undefined behavior.
8537 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
8538 * lisp.h (error, verror): Mark as printf-like functions.
8539 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
8540 Report overflow in size calculations when allocating printf buffer.
8541 Do not truncate output string at its first null byte.
8542 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
8543 Truncate the output at a character boundary, since vsnprintf does not
8544 do that.
8545 * charset.c (check_iso_charset_parameter): Convert internal
8546 character to string before calling 'error', since %c now has the
8547 printf meaning.
8548 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
8549 overflow when computing char to be passed to 'error'. Do not
8550 pass Lisp_Object to 'error'; pass the integer instead.
8551 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
8552 formatted with plain %d.
8553
8554 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
8555
8556 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
8557
8558 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
8559
8560 * xterm.c (x_catch_errors): Remove duplicate declaration.
8561
8562 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
8563
8564 * xdisp.c, lisp.h (message_nolog): Remove; unused.
8565
8566 2011-04-10 Jim Meyering <meyering@redhat.com>
8567
8568 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
8569 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
8570 return ssize_t not "int", and use size_t as the buffer length.
8571 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
8572 * gnutls.h: Update declarations.
8573 * process.c (read_process_output): Use ssize_t, to match.
8574 (send_process): Likewise.
8575
8576 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
8577
8578 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
8579
8580 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
8581
8582 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
8583 Use unsigned char, to match FcChar8 type definition.
8584
8585 * xterm.c (handle_one_xevent):
8586 * xmenu.c (create_and_show_popup_menu):
8587 * xselect.c (x_decline_selection_request)
8588 (x_reply_selection_request): Avoid type-punned deref of X events.
8589
8590 2011-04-09 Eli Zaretskii <eliz@gnu.org>
8591
8592 Fix some uses of `int' instead of EMACS_INT.
8593 * search.c (string_match_1, fast_string_match)
8594 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
8595 (scan_buffer, find_next_newline_no_quit)
8596 (find_before_next_newline, search_command, Freplace_match)
8597 (Fmatch_data): Make some `int' variables be EMACS_INT.
8598
8599 * xdisp.c (display_count_lines): 3rd argument and return value now
8600 EMACS_INT. All callers changed.
8601 (pint2hrstr): Last argument is now EMACS_INT.
8602
8603 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
8604 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
8605 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
8606 (decode_coding_utf_16, decode_coding_emacs_mule)
8607 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
8608 (decode_coding_ccl, decode_coding_charset)
8609 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
8610 (decode_coding_iso_2022, decode_coding_emacs_mule)
8611 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
8612 <char_offset, last_offset>: Declare EMACS_INT.
8613 (encode_coding_utf_8, encode_coding_utf_16)
8614 (encode_coding_emacs_mule, encode_invocation_designation)
8615 (encode_designation_at_bol, encode_coding_iso_2022)
8616 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
8617 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
8618 Declare EMACS_INT.
8619 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
8620 (encode_invocation_designation): Last argument P_NCHARS is now
8621 EMACS_INT.
8622 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
8623 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
8624
8625 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
8626 All users changed.
8627
8628 * ccl.c (Fccl_execute_on_string): Declare some variables
8629 EMACS_INT.
8630
8631 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
8632
8633 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).

8637 * process.c (Fformat_network_address): Doc fix.
8638
8639 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
8640
8641 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
8642
8643 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
8644
8645 * keyboard.c (read_char): Call Lisp function help-form-show,
8646 instead of using internal_with_output_to_temp_buffer.
8647 (Qhelp_form_show): New var.
8648 (syms_of_keyboard): Use DEFSYM macro.
8649
8650 * print.c (internal_with_output_to_temp_buffer): Function deleted.
8651
8652 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
8653
8654 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
8655
8656 * process.c (Flist_processes): Remove to Lisp.
8657 (list_processes_1): Delete.
8658
8659 2011-04-06 Eli Zaretskii <eliz@gnu.org>
8660
8661 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
8662
8663 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
8664
8665 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
8666
8667 Fix more problems found by GCC 4.6.0's static checks.
8668
8669 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
8670
8671 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
8672
8673 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
8674
8675 * xdisp.c (vmessage): Mark as a printf-like function.
8676
8677 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
8678
8679 * sound.c (sound_warning): Don't crash if arg contains a printf format.
8680
8681 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
8682 printf-like functions.
8683 (tiff_load): Add casts to remove these marks before passing them
8684 to system-supplied API.
8685
8686 * eval.c (Fsignal): Remove excess argument to 'fatal'.
8687
8688 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
8689 This avoids several warnings with gcc -Wstrict-overflow.
8690 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
8691 directly, rather than having caller test rule sign. This avoids
8692 some unnecessary tests.
8693 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
8694 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
8695 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
8696
8697 * xfont.c (xfont_text_extents): Remove var that was set but not used.
8698 (xfont_open): Avoid unnecessary tests.
8699
8700 * composite.c (composition_gstring_put_cache): Use unsigned integer.
8701
8702 * composite.h, composite.c (composition_gstring_put_cache):
8703 Use EMACS_INT, not int, for length.
8704
8705 * composite.h (COMPOSITION_DECODE_REFS): New macro,
8706 breaking out part of COMPOSITION_DECODE_RULE.
8707 (COMPOSITION_DECODE_RULE): Use it.
8708 * composite.c (get_composition_id): Remove unused local vars,
8709 by using the new macro.
8710
8711 * textprop.c (set_text_properties_1): Change while to do-while,
8712 since the condition is always true at first.
8713
8714 * intervals.c (graft_intervals_into_buffer): Mark var as used.
8715 (interval_deletion_adjustment): Return unsigned value.
8716 All uses changed.
8717
8718 * process.c (list_processes_1, create_pty, read_process_output):
8719 (exec_sentinel): Remove vars that were set but not used.
8720 (create_pty): Remove unnecessary "volatile"s.
8721 (Fnetwork_interface_info): Avoid possibility of int overflow.
8722 (read_process_output): Do adaptive read buffering even if carryover.
8723 (read_process_output): Simplify nbytes computation if buffered.
8724
8725 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
8726
8727 * syntax.c (scan_words): Remove var that was set but not used.
8728 (update_syntax_table): Use unsigned instead of int.
8729
8730 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
8731 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
8732 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
8733
8734 * print.c (print_error_message): Avoid int overflow.
8735
8736 * font.c (font_list_entities): Redo for clarity,
8737 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
8738
8739 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
8740 (font_score): Avoid potential overflow in diff calculation.
8741
8742 * fns.c (substring_both): Remove var that is set but not used.
8743 (sxhash): Redo loop for clarity and to avoid wraparound warning.
8744
8745 * eval.c (funcall_lambda): Rename local to avoid shadowing.
8746
8747 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
8748 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
8749 can always succeed if overflow has undefined behavior.
8750
8751 * search.c (boyer_moore, wordify): Remove vars set but not used.
8752 (wordify): Omit three unnecessary tests.
8753
8754 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

8758
8759 * dired.c (file_name_completion): Remove var that is set but not used.

8776
8777 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
8778
8779 * image.c (lookup_image): Remove var that is set but not used.
8780 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
8781
8782 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
8783 that are set but not used.
8784
8785 * xfns.c (make_invisible_cursor): Don't return garbage
8786 if XCreateBitmapFromData fails (Bug#8410).
8787
8788 * xselect.c (x_get_local_selection, x_handle_property_notify):
8789 Remove vars that are set but not used.
8790
8791 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
8792 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
8793
8794 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
8795 Remove var that is set but not used.
8796 (scroll_bar_windows_size): Now size_t, not int.
8797 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
8798 Check for overflow.
8799
8800 * xfaces.c (realize_named_face): Remove vars that are set but not used.
8801 (map_tty_color) [!defined MSDOS]: Likewise.
8802
8803 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
8804
8805 * coding.c: Remove vars that are set but not used.
8806 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
8807 All callers changed.
8808 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
8809 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
8810 (decode_coding_charset): Remove vars that are set but not used.
8811
8812 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
8813 that is set but not used.
8814
8815 * print.c (print_object): Remove var that is set but not used.
8816
8817 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
8818 The gnulib version avoids calling malloc in the usual case,
8819 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
8820 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
8821 * filelock.c (current_lock_owner): Likewise.
8822 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
8823 * sysdep.c: Include allocator.h, careadlinkat.h.
8824 (emacs_no_realloc_allocator): New static constant.
8825 (emacs_readlink): New function.
8826 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
8827 ../lib/careadlinkat.h.
8828
8829 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
8830
8831 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
8832 first non-nil return value).
8833
8834 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
8835
8836 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
8837 if not defined (Bug#8403).
8838
8839 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
8840
8841 * xdisp.c (display_count_lines): Remove parameter `start',
8842 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
8843 (get_char_face_and_encoding): Remove parameter `multibyte_p',

8853 do not dereference NULL upon failed strdup
8854 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
8855 (ns_get_family): Likewise.
8856
8857 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
8858
8859 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
8860
8861 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
8862
8863 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
8864 later (Bug#8403).
8865
8866 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
8867
8868 Add lexical binding.
8869
8870 * window.c (Ftemp_output_buffer_show): New fun.
8871 (Fsave_window_excursion):
8872 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
8873
8874 * lread.c (lisp_file_lexically_bound_p): New function.
8875 (Fload): Bind Qlexical_binding.
8876 (readevalloop): Remove `evalfun' arg.
8877 Bind Qinternal_interpreter_environment.
8878 (Feval_buffer): Bind Qlexical_binding.
8879 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
8880 Mark as dynamic.
8881 (syms_of_lread): Declare `lexical-binding'.
8882
8883 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
8884
8885 * keyboard.c (eval_dyn): New fun.
8886 (menu_item_eval_property): Use it.
8887
8888 * image.c (parse_image_spec): Use Ffunctionp.
8889
8890 * fns.c (concat, mapcar1): Accept byte-code-functions.
8891
8892 * eval.c (Fsetq): Handle lexical vars.
8893 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
8894 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
8895 (FletX, Flet): Obey lexical binding.
8896 (Fcommandp): Handle closures.
8897 (Feval): New `lexical' arg.
8898 (eval_sub): New function extracted from Feval. Use it almost
8899 everywhere where Feval was used. Look up vars in lexical env.
8900 Handle closures.
8901 (Ffunctionp): Move from subr.el.
8902 (Ffuncall): Handle closures.
8903 (apply_lambda): Remove `eval_flags'.
8904 (funcall_lambda): Handle closures and new byte-code-functions.
8905 (Fspecial_variable_p): New function.
8906 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
8907 but without exporting it to Lisp.
8908
8909 * doc.c (Fdocumentation, store_function_docstring):
8910 * data.c (Finteractive_form): Handle closures.
8911
8912 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
8913 interactive spec.
8914
8915 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
8916 New byte-codes.
8917 (exec_byte_code): New function extracted from Fbyte_code to handle new
8918 calling convention for byte-code-functions. Add new byte-codes.
8919
8920 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
8921
8922 * alloc.c (Fmake_symbol): Init new `declared_special' field.
8923
8924 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
8925
8926 * xdisp.c (redisplay_internal): Fix prototype.
8927
8928 2011-03-31 Eli Zaretskii <eliz@gnu.org>
8929
8930 * xdisp.c (SCROLL_LIMIT): New macro.
8931 (try_scrolling): Use it when setting scroll_limit.
8932 Limit scrolling to 100 screen lines.
8933 (redisplay_window): Even when falling back on "recentering",
8934 position point in the window according to scroll-conservatively,
8935 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
8936
8937 (try_scrolling): When point is above the window, allow searching
8938 as far as scroll_max, or one screenful, to compute vertical
8939 distance from PT to the scroll margin position. This prevents
8940 try_scrolling from unnecessarily failing when
8941 scroll-conservatively is set to a value slightly larger than the
8942 window height. Clean up the case of PT below the margin at bottom
8943 of window: scroll_max can no longer be INT_MAX. When aggressive
8944 scrolling is in use, don't let point enter the opposite scroll
8945 margin as result of the scroll.
8946 (syms_of_xdisp) <scroll-conservatively>: Document the
8947 threshold of 100 lines for never-recentering scrolling.
8948
8949 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

8953 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
8954 (message_log_check_duplicate): Remove parameters `prev_bol' and
8955 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
8956 (redisplay_internal): Remove parameter `preserve_echo_area',
8957 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
8958
8959 * indent.c (Fvertical_motion):
8960 * window.c (window_scroll_pixel_based, Frecenter):
8961 Don't pass `need_y_p' to `move_it_by_lines'.
8962
8963 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
8964
8965 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
8966 steal a few bits to be more compact.

8968 Remove unneeded casts.
8969
8970 * bytecode.c (Fbyte_code): CAR and CDR can GC.
8971
8972 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
8973
8974 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
8975 binding" message (bug#7967).
8976
8977 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
8978
8979 Fix more problems found by GCC 4.6.0's static checks.
8980
8981 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
8982 Remove unused local var.
8983
8984 * editfns.c (Fmessage_box): Remove unused local var.
8985
8986 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
8987 (note_mode_line_or_margin_highlight, note_mouse_highlight):
8988 Omit unused local vars.
8989 * window.c (shrink_windows): Omit unused local var.
8990 * menu.c (digest_single_submenu): Omit unused local var.
8991 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
8992 Omit unused local var.
8993
8994 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
8995 Don't assume string length fits in int.
8996 (keyremap_step, read_key_sequence): Use size_t for sizes.
8997 (read_key_sequence): Don't check last_real_key_start redundantly.
8998
8999 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
9000 instead of alloca (Bug#8344).
9001
9002 * eval.c (Fbacktrace): Don't assume nargs fits in int.
9003 (Fbacktrace_frame): Don't assume nframes fits in int.
9004
9005 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
9006
9007 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
9008 concerns.
9009
9010 * term.c (produce_glyphless_glyph): Remove unnecessary test.
9011
9012 * cm.c (calccost): Turn while-do into do-while, for clarity.
9013
9014 * keyboard.c (syms_of_keyboard): Use the same style as later
9015 in this function when indexing through an array. This also
9016 works around GCC bug 48267.
9017
9018 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
9019
9020 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
9021

9023 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
9024
9025 * keyboard.c, keyboard.h (num_input_events): Now size_t.
9026 This avoids undefined behavior on integer overflow, and is a bit
9027 more convenient anyway since it is compared to a size_t variable.
9028
9029 Variadic C functions now count arguments with size_t, not int.
9030 This avoids an unnecessary limitation on 64-bit machines, which
9031 caused (substring ...) to crash on large vectors (Bug#8344).
9032 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
9033 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

9040 (funcall_lambda, mark_backtrace): Likewise.
9041 * fns.c (concat): Likewise.
9042 * frame.c (x_set_frame_parameters): Likewise.
9043 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
9044 0 if not found, not -1. All callers changed.
9045
9046 * alloc.c (garbage_collect): Don't assume stack size fits in int.
9047 (stack_copy_size): Now size_t, not int.
9048 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

9073 Vcommand_hook_internal.
9074

9086
9087 * print.c (strout): Remove parameter `multibyte', unused since

9138 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
9139
9140 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
9141
9142 * w32.c (read_unc_volume): Use parameter `henum', instead of
9143 global variable `wget_enum_handle'.
9144
9145 * keymap.c (describe_vector): Remove parameters `indices' and
9146 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
9147 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
9148
9149 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.

9259 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
9260
9261 Fix more problems found by GCC 4.5.2's static checks.
9262
9263 * coding.c (encode_coding_raw_text): Avoid unnecessary test
9264 the first time through the loop, since we know p0 < p1 then.
9265 This also avoids a gcc -Wstrict-overflow warning.
9266
9267 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
9268 leading to a memory leak, possible in functions like
9269 load_charset_map_from_file that can allocate an unbounded number
9270 of objects (Bug#8318).
9271
9272 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
9273 that could (at least in theory) be that large.
9274
9275 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
9276 This is less likely to overflow, and avoids undefined behavior if
9277 overflow does occur. All callers changed. Use strtoul to scan
9278 for the unsigned long integer.
9279 (pint2hrstr): Simplify and tune code slightly.
9280 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
9281

9283 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
9284
9285 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
9286 This also avoids a warning with gcc -Wstrict-overflow.

9288 This also avoids a warning with gcc -Wstrict-overflow.
9289
9290 * fileio.c (Fcopy_file): Report error if fchown or fchmod
9291 fail (Bug#8306).
9292
9293 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
9294
9295 * process.c (Fmake_network_process): Use socklen_t, not int,
9296 where POSIX says socklen_t is required in portable programs.
9297 This fixes a porting bug on hosts like 64-bit HP-UX, where
9298 socklen_t is wider than int (Bug#8277).
9299 (Fmake_network_process, server_accept_connection):
9300 (wait_reading_process_output, read_process_output):
9301 Likewise.
9302
9303 * process.c: Rename or move locals to avoid shadowing.

9310 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
9311 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
9312
9313 Make tparam.h and terminfo.c consistent.
9314 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
9315 Include tparam.h instead, since it declares them.
9316 * cm.h (PC): Remove extern decl; tparam.h now does this.
9317 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
9318 * terminfo.c: Include tparam.h, to check interfaces.
9319 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
9320 (tparam): Adjust signature to match interface in tparam.h;
9321 this removes some undefined behavior. Check that outstring and len
9322 are zero, which they always are with Emacs.
9323 * tparam.h (PC, BC, UP): New extern decls.
9324
9325 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

9339
9340 * composite.c (composition_compute_stop_pos): Rename local to
9341 avoid shadowing.
9342 (composition_reseat_it): Remove unused locals.
9343 (find_automatic_composition, composition_adjust_point): Likewise.
9344 (composition_update_it): Mark var as initialized.
9345 (find_automatic_composition): Mark vars as initialized,
9346 with a FIXME (Bug#8290).
9347
9348 character.h: Rename locals to avoid shadowing.
9349 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
9350 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
9351 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
9352 (BUF_DEC_POS): Be more systematic about renaming local temporaries
9353 to avoid shadowing.

9362 Rename locals to avoid shadowing.
9363
9364 * sound.c (wav_play, au_play, Fplay_sound_internal):
9365 Fix pointer signedness.
9366 (alsa_choose_format): Remove unused local var.
9367 (wav_play): Initialize a variable to 0, to prevent undefined
9368 behavior (Bug#8278).
9369
9370 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
9371
9372 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
9373
9374 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
9375 clobbering (Bug#8298).
9376 * sysdep.c (sys_subshell): Likewise.
9377 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
9378
9379 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
9380 This should get cleaned up, so that child_setup has the
9381 same signature on all platforms.
9382
9383 * callproc.c (call_process_cleanup): Now static.
9384 (relocate_fd): Rename locals to avoid shadowing.
9385
9386 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
9387
9388 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
9389 not to be necessary, and produces flickering.
9390
9391 2011-03-20 Glenn Morris <rgm@gnu.org>
9392
9393 * config.in: Remove file.
9394

9409 * xfaces.c (Fx_load_color_file):
9410 Read color file from absolute filename (bug#8250).
9411
9412 2011-03-19 Juanma Barranquero <lekktu@gmail.com>

9414 * makefile.w32-in: Update dependencies.
9415

9425 (sigchld_handler): Now static.
9426
9427 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
9428 That way, the code declares only the vars that it needs.

9430 * s/cygwin.h (PTY_ITERATION): Likewise.
9431 * s/darwin.h (PTY_ITERATION): Likewise.

9433
9434 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.

9446 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
9447
9448 * deps.mk (unexalpha.o): Remove; unused.

9510 Move decls here, to check interfaces.
9511 * process.c (get_operating_system_release): Move decl to lisp.h.

9552 Use functions, not macros, for up- and down-casing (Bug#8254).
9553 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
9554 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
9555 to use the following functions instead of these macros.
9556 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
9557 EMACS_INT, since callers assume the returned value fits in int.
9558 (upcase1): Likewise, for UPCASE_TABLE.
9559 (uppercasep, lowercasep, upcase): New static inline functions.
9560 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

9572 (WORDCHAR_P): Likewise. This one is never needed, but is used
9573 only in a comment talking about a compiler bug, so put inside
9574 the #if 0 of that comment.
9575 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
9576 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

9588
9589 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
9590

9593 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
9594 Rename locals to avoid shadowing.
9595 (Fvertical_motion): Mark locals as initialized.

9606 of the new macros.
9607 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second

9612 Rename locals to avoid shadowing.
9613
9614 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
9615 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
9616 dired.c's scmp function, had undefined behavior.
9617 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
9618 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
9619 * buffer.h: ... to here, because these macros use current_buffer,
9620 and the new implementation with inline functions needs to have
9621 current_buffer in scope now, rather than later when the macros
9622 are used.
9623 (downcase, upcase1): New static inline functions.
9624 (DOWNCASE, UPCASE1): Reimplement using these functions.
9625 This avoids undefined behavior in expressions like

9633 above can use them.
9634
9635 * dired.c (directory_files_internal_unwind): Now static.
9636
9637 * fileio.c (file_name_as_directory, directory_file_name):

9639 Now static.
9640 (file_name_as_directory): Use const pointers when appropriate.
9641 (Fexpand_file_name): Likewise. In particular, newdir might

9644 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
9645 signedness issues.

9651 to avoid shadowing.
9652
9653 * marker.c (bytepos_to_charpos): Remove; unused.

9656 so that gcc does not warn that these functions aren't declared.
9657
9658 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
9659 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

9664 (lock_file_1): Rename local to avoid shadowing.
9665
9666 * buffer.c (fix_overlays_before): Mark locals as initialized.
9667 (fix_start_end_in_overlays): Likewise. This function should be
9668 simplified by using pointers-to-pointers, but that's a different
9669 matter.
9670 (switch_to_buffer_1): Now static.
9671 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
9672 (report_overlay_modification): Rename locals to avoid shadowing.
9673
9674 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
9675 Fix pointer signedness issue.

9677 to suppress a gcc -Wclobbered warning that does not seem to be right.
9678 (MAXPATHLEN): Define only if needed.
9679
9680 * process.c (serial_open, serial_configure): Move decls from here ...

9688
9689 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
9690 (copy_keymap_item, append_key, push_text_char_description):
9691 Now static.
9692 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
9693 (DENSE_TABLE_SIZE): Remove; unused.
9694 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
9695 (describe_map_tree):
9696 Rename locals to avoid shadowing.
9697
9698 * keyboard.c: Declare functions static if they are not used elsewhere.
9699 (echo_char, echo_dash, cmd_error, top_level_2):

9714
9715 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
9716 (DEFINE_DUMMY_FUNCTION): New macro.

10081 Use const pointers where appropriate.
