13 2013-01-25 Eli Zaretskii <eliz@gnu.org>
15 * w32.c (max_filename_mbslen): New function.
16 (normalize_filename, readdir): Use it to detect locales where ANSI
17 encoding of file names uses a double-byte character set (DBCS).
18 If a DBCS encoding is used, advance by characters using
19 CharNextExA, instead of incrementing a 'char *' pointer. Use
20 _mbslwr instead of _strlwr. (Bug#13515)
22 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
23 request of memory reservation to 1.7GB. (Bug#13065)
25 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
27 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
28 at check_extra_latin label. (Bug#13505)
30 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
32 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
33 Avoid redundant calls to strlen.
35 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
37 Drop async_visible and async_iconified fields of struct frame.
38 This is possible because async input is gone; for details, see
39 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
40 * frame.h (struct frame): Remove async_visible and async_iconified
41 members, convert garbaged to unsigned bitfield. Adjust comments.
42 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
43 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
44 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
45 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
46 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
48 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
49 properly. Likewise for obscured.
51 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
54 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
56 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
58 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
59 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
61 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
63 * xdisp.c (message2, message2_nolog): Remove functions.
64 (message3, message3_nolog): Extract nbytes and multibyteness directly
65 from the string. Change all callers.
66 (message3_nolog): Don't set message_enable_multibyte since set_message
68 (message1, message1_nolog): Use message3.
69 (vmessage): Use a stack allocated buffer rather than f->message_buf.
70 (with_echo_area_buffer): Remove last two arguments. Update all callers.
71 (set_message): Drop all but the second arg, which has to be a string.
72 (set_message_1): Simplify now that we know that a1 is NULL and the
73 second arg is a string.
74 * frame.h (struct frame): Remove `message_buf' field.
75 Use glyphs_initialized_p instead.
76 (FRAME_MESSAGE_BUF): Remove macro.
77 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
78 * lisp.h (message2, message2_nolog): Remove declarations.
79 (message3, message3_nolog): Update declarations.
80 * keyboard.c (read_char_minibuf_menu_text)
81 (read_char_minibuf_menu_width): Remove vars.
82 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
83 to correctly handle multibyte strings.
84 * frame.c (delete_frame): Don't free message_buf any more.
85 * editfns.c (message_text, message_length): Remove vars.
86 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
87 * fileio.c (auto_save_error): Use message3 instead of message2.
88 * dispnew.c (adjust_frame_message_buffer): Remove function.
90 2013-01-23 Eli Zaretskii <eliz@gnu.org>

97 * insdel.c (prepare_to_modify_buffer): Force redisplay if
98 hidden buffer is prepared to modification (Bug#13164).
100 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
102 * window.h (struct window): Change window_end_valid member from
103 Lisp_Object to a bitfield. Adjust comments.
104 (wset_window_end_valid): Remove.
105 * window.c (adjust_window_count): Clear window_end_valid.
106 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
107 (Fwindow_line_height, set_window_buffer, Frecenter)
108 (Fsplit_window_internal, Fdelete_other_windows_internal)
109 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
110 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
111 * xdisp.c (check_window_end, reconsider_clip_changes)
112 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
113 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
114 (find_first_unchanged_at_end_row, try_window_id): Likewise.
116 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
118 * xdisp.c (mark_window_display_accurate): Simplify the loop
119 assuming that the only one of vchild, hchild or buffer window
120 slots is non-nil. Call mark_window_display_accurate_1 for
121 the leaf windows only.
122 (mark_window_display_accurate_1): Always assume leaf window.
125 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
127 * emacs.c (Qkill_emacs_hook): Now static.
129 * fileio.c (Finsert_file_contents): Simplify.
130 Remove unnecessary assignments and tests.
132 2013-01-21 Eli Zaretskii <eliz@gnu.org>
134 * w32.c (acl_set_file): Don't test for errors unless
135 set_file_security returns FALSE. Avoids spurious errors when
138 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
140 * fileio.c (Finsert_file_contents): Revert code introduced at
141 2013-01-18 in favor of the simpler and generally better fix.
142 Save stack space by removing 'buffer' and reusing 'read_buf'
145 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
147 * lisp.h (eabs): Define unconditionally (Bug#13419).
148 The old "#if !defined (eabs)" was an unnecessary revenant of back
149 when this macro was called "abs". Document 'eabs' better.
151 2013-01-19 Glenn Morris <rgm@gnu.org>
153 * fns.c (Frandom): Doc fix.
155 2013-01-19 Eli Zaretskii <eliz@gnu.org>
157 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
158 segfault when there are lots of overlays.
160 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
161 when there are lots of overlays. See
162 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
163 for the details and a way to reproduce.
165 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
167 * fileio.c: Use O_APPEND to append.
168 This corresponds better to the natural interpretation of "append",
169 and avoids the need to open the output file twice, or to invoke
170 lseek when APPEND is neither nil nor a number.
171 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
172 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
173 file possibly twice, and lseeking to its end; this avoids the
174 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
175 at the same time: the combination is never needed and apparently
176 it doesn't work with DOS_NT.
178 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
179 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
181 Allow floating-point file offsets.
182 Problem reported by Vitalie Spinu in
183 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
184 * fileio.c (emacs_lseek): Remove.
185 (file_offset): New function.
186 (Finsert_file_contents, Fwrite_region): Use it.
188 2013-01-19 Chong Yidong <cyd@gnu.org>
190 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
191 aborting on Fsignal (Bug#13289).
193 2013-01-19 Eli Zaretskii <eliz@gnu.org>
195 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
196 set_file_security as failure due to insufficient privileges.
197 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
198 (fstat): Return owner and group like 'stat' and 'lstat' do.
200 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
202 Work around bug in CIFS and vboxsf file systems (Bug#13149).
203 The bug was observed on Ubuntu operating inside a virtual machine,
204 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
205 The workaround introduces a race condition on non-buggy hosts,
206 but it's an unlikely race and anyway there's a nearly identical
207 nearby race that can't be fixed.
208 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
210 (Fwrite_region): Test for file system time stamp bug.
211 (init_fileio): New function.
212 * lisp.h (init_fileio): Declare it.
213 * emacs.c (main): Call it.
215 * fileio.c (Finsert_file_contents): Simplify new diagnostic
216 and make it more consistent with other stat-failure diagnostics.
218 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
220 Fix crash when inserting data from non-regular files. See
221 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
222 for the error description produced by valgrind.
223 * fileio.c (read_non_regular): Rename to read_contents.
224 Free Lisp_Save_Value object used to pass parameters.
225 (read_non_regular_quit): Rename to read_contents_quit.
226 (Finsert_file_contents): Redesign internal file reading loop to adjust
227 gap and end positions after each read and so help make_gap to work
228 properly. Do not signal an I/O error too early and so do not leave
229 not yet decoded characters in a buffer, which was the reason of
230 redisplay crash. Use list2 to build return value. Adjust comments.
232 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
234 Close a race when statting and reading files (Bug#13149).
235 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
236 This avoids a race if the file is renamed between stat and open.
237 This race is not the problem originally noted in Bug#13149;
238 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
240 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

248 * alloc.c (format_save_value): Rename to make_save_value.
249 (make_save_pointer): New function.
250 (record_xmalloc): Use make_save_pointer.
251 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
252 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
253 Change users of make_save_value to make_save_pointer.
254 Likewise for format_save_value and make_save_value.

273 (Finsert_file_contents): Convert trytry to ptrdiff_t. Use
274 format_save_value to pass parameters to read_non_regular.
275 (read_non_regular): Use XSAVE_ macros to extract parameters.
277 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
279 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
281 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
283 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
284 extraction from any Lisp_Save_Value slot. Add type checking.
285 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
286 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
287 * xselect.c: All users changed.
289 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
291 Some convenient bits to deal with Lisp_Save_Values.

306 * dired.c (directory_files_internal_unwind):
307 * fileio.c (do_auto_save_unwind):
308 * gtkutil.c (pop_down_dialog):
309 * keymap.c (map_keymap_char_table_item):
310 * lread.c (load_unwind):
311 * nsmenu.m (pop_down_menu):
312 * print.c (print_object) [GC_MARK_STACK]:
313 * xfns.c (clean_up_file_dialog):
314 * xmenu.c (cleanup_widget_value_tree):
315 Omit casts between XSAVE_POINTER and a pointer type.
317 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
319 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
320 * eval.c (eval_sub): Protect `form' from being GCed before its
321 car and cdr becomes protected with the backtrace entry.
323 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
325 Make Lisp_Save_Value more versatile storage for up to four objects.

333 (free_misc): Likewise. Adjust comment.
334 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
335 (free_save_value): Likewise.
336 (mark_object): Likewise.
337 * editfns.c (save_excursion_save): Pack everything within
338 Lisp_Save_Value and so avoid xmalloc.
339 (save_excursion_restore): Adjust to match new layout. Use free_misc
340 because we do not allocate extra memory any more. Add eassert.
341 * print.c (print_object): New code to print Lisp_Save_Value. Do not
342 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
343 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
344 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:
345 Use XSAVE_POINTER and XSAVE_INTEGER where appropriate.
347 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

357 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
358 Move handlers here from emacs.c; they were out of place.
360 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
362 * xterm.c (syms_of_xterm): Adjust documentation for
363 scroll-bar-adjust-thumb-portion.

383 (nsfont_open): Move block_input earlier. Add unblock_input before early
385 (nsfont_draw): Add block/unblock_input calls.
387 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
389 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs

401 * insdel.c (Fcombine_after_change_execute, syms_of_insdel): Fix
402 ambiguous doc string cross-reference(s).
404 * keyboard.c (Fcommand_execute, syms_of_keyboard): Fix ambiguous
405 doc string cross-reference(s).
407 * window.c (Fwindow_point, syms_of_window): Fix ambiguous doc
408 string cross-reference(s).
410 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
412 Avoid unnecessary byte position calculation for the gap movement.
413 Since all users of move_gap do CHAR_TO_BYTE for other purposes
414 anyway, all of them should use move_gap_both instead.
415 * lisp.h (move_gap): Remove prototype.
416 * insdel.c (move_gap): Remove.
417 (move_gap_both): Add eassert.
418 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.
419 * xml.c (parse_region): Likewise.
421 2013-01-11 Paul Eggert <eggert@cs.ucla.edu>
423 emacsclient -t should not suspend Emacs server (Bug#13387)
424 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
426 * term.c (init_tty): Use them instead of rolling our own code.
427 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
428 switches from 'signal' to 'pthread_sigmask', which is safer in
429 multithreaded applications.
430 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
431 which has already arranged for that.
432 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
433 This is the main part of the bug fix.
435 2013-01-10 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)
437 * gtkutil.c (xg_initialize): Add ifdef HAVE_FREETYPE around

440 2013-01-10 Dmitry Antipov <dmantipov@yandex.ru>
442 Omit buffer_slot_type_mismatch and use generic predicates to enforce
443 the type of per-buffer values where appropriate.
444 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
445 predicate, which is how it's really used now. Adjust comment.
446 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
447 * buffer.c (buffer_slot_type_mismatch): Remove.
448 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

451 fill-column, left-margin, tab-width, buffer-saved-size,
452 left-margin-width, right-margin-width, left-fringe-width,
453 right-fringe-width, scroll-bar-width and buffer-display-count.
454 Use Qstringp for default-directory, buffer-file-name,
455 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
456 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
458 * data.c (store_symval_forwarding): Adjust to call the predicate.
460 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
462 * w32.c (get_name_and_id, acl_set_file):
463 * w32term.c (w32fullscreen_hook): Remove unused local variables.

501 trailing dash is properly added.
503 2013-01-05 Eli Zaretskii <eliz@gnu.org>
505 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
506 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
507 digits for buffer positions, before misalignment starts.
508 Display "0" for integer "object" field.
509 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
510 Display the newline glyph more unambiguously.
512 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
514 * nsterm.m (ns_draw_underwave):
515 * w32term.c (w32_draw_underwave):
516 * xterm.c (x_draw_underwave): Make underwave look more triangular
517 and also degrade gracefully for small fonts. (Bug#13000)
519 * nsterm.m (ns_draw_text_decoration):
520 * w32term.c (x_draw_glyph_string):
521 * xterm.c (x_draw_glyph_string): Don't use previous underline
522 thickness and position if previous underline type is underwave.
524 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
526 * fileio.c (Ffile_acl): Undocument return format.

532 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>
535 * dired.c (file_name_completion):
536 * doc.c (get_doc_string):
537 * floatfns.c (round2):
538 * font.c (font_score, font_delete_unmatched):
539 * fringe.c (compute_fringe_widths):
540 * lread.c (read_list):
541 * minibuf.c (Ftry_completion):
542 * term.c (tty_ins_del_lines):
543 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
544 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
546 2012-12-31 Eli Zaretskii <eliz@gnu.org>
548 * w32.c (unsetenv): Set up the string passed to _putenv
550 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
551 for the bug this caused.
553 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
555 * coding.c (Qmac): Now static.
557 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
559 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
560 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
561 handlebox_widget. Set toolbar_in_hbox to false/true, set
562 toolbar_is_packed to true.
563 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
564 (update_frame_tool_bar): Check toolbar_is_packed for packing.
565 Show all on TOOLBAR_TOP_WIDGET.
566 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
567 by TOOLBAR_TOP_WIDGET.
568 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
569 Check toolbar_is_packed.
570 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
571 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
572 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
574 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
575 (xg_update_menubar): Update title only if
576 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
577 (xg_update_submenu): Skip tearoff only if
578 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
579 (xg_initialize): Initialize xg_detached_menus only if
580 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
582 * xterm.h (struct x_output): Surround handlebox_widget with
583 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
584 toolbar_in_hbox is bool.
586 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
588 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
589 (LIBS_GNUSTEP): Define.
590 (LIBES): Add $(LIBS_GNUSTEP).
591 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
593 2012-12-30 Eli Zaretskii <eliz@gnu.org>
595 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
596 continuation glyph on a TTY with an indication of an empty line.
599 2012-12-29 Eli Zaretskii <eliz@gnu.org>
601 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
602 file's SELinux context or ACLs successfully set, nil otherwise.
604 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
606 * w32proc.c (reader_thread): Avoid passing NULL handles to
607 SetEvent and WaitForSingleObject.
609 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
611 Port EXTERNALLY_VISIBLE to Clang 3.2.
612 * conf_post.h (__has_attribute): New macro.
613 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
615 2012-12-27 Glenn Morris <rgm@gnu.org>
617 * cygw32.c (Fcygwin_convert_file_name_to_windows)
618 (Fcygwin_convert_file_name_from_windows): Doc fixes.
620 2012-12-27 Eli Zaretskii <eliz@gnu.org>
622 * fileio.c (file_name_as_directory, directory_file_name):
623 Accept an additional argument MULTIBYTE to indicate whether the input C
624 came from a multibyte or a unibyte Lisp string; all callers
625 adjusted. Don't assume the input string is always multibyte.
627 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
628 don't ENCODE_FILE them, and return a unibyte string if the input
630 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
631 don't assume the input strings will always be multibyte. If the
632 input strings are multibyte, decode strings obtained from C
635 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
637 * lisp.h (toplevel): Add two notices to the comment about
638 defining a new Lisp data type.
639 * print.c (print_object): If Lisp_Save_Value object's pointer
640 is the address of a memory area containing Lisp_Objects, try
642 * alloc.c (valid_lisp_object_p): Adjust comment.
644 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
646 * keyboard.c (record_asynch_buffer_change): Initialize an event
647 only if it's really needed.
648 * frame.h (enum output_method): Remove output_mac member since
649 it's a leftover from the deleted code.
650 * frame.c (Fframep): Adjust user here ...
651 * terminal.c (Fterminal_live_p): ... and here.
652 * coding.c (Qmac): Now here because it's only used to denote
653 end-of-line encoding type.
654 (syms_of_coding): DEFSYM it.
655 * frame.h (Qmac): Remove duplicated declaration.
657 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
659 * window.c (select_window_1): Now static, since it's used only here.
661 2012-12-25 Eli Zaretskii <eliz@gnu.org>
663 * window.c (window_body_cols): Subtract display margins from the
664 window body width on TTYs as well. See
665 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
666 for the original report.
668 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
670 * xdisp.c (redisplay_window): Remove inner local variable
671 because the outer shadowed one has the same meaning.
672 * xterm.h (struct x_output): Remove toolbar_detached member since it's
674 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
675 (xg_create_tool_bar): Adjust users.
677 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
679 * buffer.h (BUF_COMPACT): New macro to follow the common style.
680 * buffer.c (Fget_buffer_create): Use it to set compact field of
681 struct buffer_text to avoid accessing an uninitialized value
682 when compact_buffer is called for the first time.
683 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
684 (Fset_buffer_modified_p): Use buffer_window_count to check
685 whether the buffer is displayed in some window.
686 * xdisp.c (message_dolog): Likewise.
688 2012-12-23 Eli Zaretskii <eliz@gnu.org>
690 * w32.c (acl_set_file): If setting the file security descriptor
691 fails, and the new DACL is identical to the existing one, silently
692 return success. This fixes problems for users backing up their
693 own files without having the necessary privileges for setting
694 security descriptors.
696 * w32proc.c (reader_thread): Do not index fd_info[] with negative
698 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
699 after WaitForSingleObject returns normally. This expedites reader
700 thread shutdown when delete_child triggers it.
701 (reap_subprocess): More accurate commentary for why we call
702 delete_child only when cp->fd is negative.
704 * w32.c (sys_close): Do not call delete_child on a subprocess
705 whose handle is not yet closed. Instead, set its file descriptor
706 to a negative value, so that reap_subprocess will call
707 delete_child on that subprocess when its SIGCHLD arrives.
708 This avoids closing handles used for communications between sys_select
709 and reader_thread, which doesn't give sys_select a chance to
710 notice that the process exited and invoke the SIGCHLD handler for
713 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
715 * nsfns.m (Fns_do_applescript): Run event loop until script has
716 been executed (Bug#12969).
717 (ns_run_ascript): Chech as_script for nil, set to nil after
720 2012-12-22 Martin Rudalics <rudalics@gmx.at>
722 * window.c (Fselect_window): Reword doc-string (Bug#13248).

726 * w32term.c (w32fullscreen_hook): New function.
727 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
729 2012-12-21 Eli Zaretskii <eliz@gnu.org>
731 * fileio.c (Finsert_file_contents): Doc fix.
733 * w32proc.c (new_child, delete_child, find_child_pid): For a
734 subprocess, consider its slot being in use as long as its process
735 handle (procinfo.hProcess) is not NULL. This avoids reusing the
736 slot when a new process is started immediately after killing
737 another one, without waiting enough time for the first process to
738 be reaped and resources allocated for it be orderly freed.
740 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
742 2012-12-21 Chong Yidong <cyd@gnu.org>
744 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
746 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
748 2012-12-21 Eli Zaretskii <eliz@gnu.org>
750 * w32.c (get_name_and_id): Always pass NULL as the first argument
751 of lookup_account_sid. Avoids crashes with UNC file names that
752 refer to DFS domains, not to specific machine names. (Bug#12621)
753 Remove now unused argument FNAME; all callers changed.
754 (get_file_owner_and_group): Remove now unused argument FNAME; all
757 2012-12-21 Chong Yidong <cyd@gnu.org>
759 * editfns.c (Finsert_char): Since read-char-by-name now signals an
760 error for invalid chars, don't check for a nil return value.
762 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
764 Avoid calls to CHAR_TO_BYTE if byte position is known.
765 * editfns.c (make_buffer_string_both): Use move_gap_both.
766 (Fbuffer_string): Use make_buffer_string_both.
767 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
769 (buf_bytepos_to_charpos): Likewise.
770 (charpos_to_bytepos): Remove.
771 * fileio.c (Finsert_file_contents): Use move_gap_both.
772 * search.c (Freplace_match): Likewise.
773 * process.c (process_send_region): Likewise. Use convenient
774 names for byte positions.
775 * lisp.h (charpos_to_bytepos): Remove prototype.
776 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
777 * insdel.c (move_gap): Likewise.
779 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
781 * xdisp.c (redisplay_internal): Remove now-unused local.
783 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
785 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
786 (redisplay_internal): Don't bother selecting the frame to get the
787 proper value of frame-local variables (bug#13225).
789 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
791 * textprop.c (set_text_properties_1): Do not allow NULL interval.
792 Rename 4th argument since it may be buffer or string. Adjust comment.
793 * intervals.c (graft_intervals_info_buffer): Find an interval here.
795 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
797 * coding.c (Fdetect_coding_region): Do not check start and end with
798 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
799 (code_convert_region): Likewise.
801 2012-12-18 Eli Zaretskii <eliz@gnu.org>
803 * w32.c (acl_get_file, acl_set_file): Run the file name through
804 map_w32_filename, and resolve any symlinks in the file name, like
806 (acl_set_file): Call revert_to_self, if any privileges were
809 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
811 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
812 ($(BLD)/w32.$(O)): Update dependencies.
814 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
816 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
817 propagate redisplay's scrolling (if any) to the right window.
818 (redisplay_internal): Use ensure_selected_frame.
819 (display_mode_lines): Complete last fix.
820 * window.c (select_window_1): New func, extracted from select_window.
821 (select_window): Use it.
822 * window.h (select_window_1): Declare.
824 2012-12-17 Eli Zaretskii <eliz@gnu.org>
826 Emulate Posix ACL APIs on MS-Windows.
827 * w32.c: Include sddl.h and sys/acl.h.
828 (SDDL_REVISION_1): Define if not already defined.

846 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
848 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
850 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
851 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
852 for some of that bug's symptoms can now cause Emacs to abort.
853 Remove the workaround.
854 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
855 The bug that caused SIGCHLD to get lost has been fixed, and the
856 workaround for it can now cause Emacs to abort.
858 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
860 * sysdep.c (emacs_abort): Bump backtrace size to 40.
861 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
862 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
864 2012-12-16 Romain Francoise <romain@orebokech.com>
866 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
867 (Fcopy_file): Change last arg to `preserve_extended_attributes'
868 and copy ACL entries of file in addition to SELinux context if set.

871 * Makefile.in (LIBACL_LIBS): New macro.
874 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
876 * fileio.c (internal_delete_file): Use bool for boolean.
878 2012-12-15 Eli Zaretskii <eliz@gnu.org>
880 Fix bug #13079 on MS-Windows with temp files not being deleted.
881 * w32.h (_child_process): New members input_file and
883 (register_child): First argument is now pid_t.
884 (record_infile, record_pending_deletion): New prototypes.
886 * w32proc.c (new_child): Initialize input_file and
887 pending_deletion members of the child.
888 (delete_child): Delete the child's temporary input file, if any,
889 that is pending deletion.
890 (register_child): First argument is now pid_t.
891 (record_infile, record_pending_deletion): New functions.
892 (reap_subprocess): Fix a typo in DebPrint string.
893 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
895 * fileio.c (internal_delete_file): Return an int again: non-zero
896 if delete-file succeeds, zero otherwise.
898 * lisp.h (internal_delete_file): Adjust prototype.
900 * callproc.c (Fcall_process): Don't overwrite infile with result
902 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
903 asynchronous subprocess, record the name of the input file name,
905 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
906 delete the file, record it as pending deletion when the subprocess
909 2012-12-14 Eli Zaretskii <eliz@gnu.org>
911 * editfns.c [HAVE_PWD_H]: Include grp.h.
913 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
915 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
917 Fix permissions bugs with setgid directories etc. (Bug#13125)
918 * dired.c (Ffile_attributes): Return t as the 9th attribute,
919 to mark it as a placeholder. The old value was often wrong.
920 The only user of this attribute has been changed to use
921 file-ownership-preserved-p instead, with its new group arg.
922 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
924 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

929 2012-12-14 Eli Zaretskii <eliz@gnu.org>
931 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
932 try to get accurate owner and group information from NT file
933 security APIs. This is to make most callers of 'stat' and
934 'lstat', which don't need that information, much faster.
936 * dired.c (Ffile_attributes) [WINDOWSNT]:
937 Set w32_stat_get_owner_group to a non-zero value, to request accurate
938 owner and group information from 'lstat'.
940 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
942 * fileio.c (Finsert_file_contents): Don't put tail into head area,
943 as that confuses set-auto-coding, so insist on the head-read
944 returning the full 1024 bytes. Let lseek compute the tail offset;
945 less work for us. Do not ignore I/O errors when reading the tail.
947 * xdisp.c: Minor style fixes.
948 (init_iterator): Hoist assignment out of if-expression.
949 (markpos_of_region): Callers now test for sign, not for -1.
951 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
953 Minor redisplay optimization when the region length is zero.
954 * xdisp.c (markpos_of_region): New function.
955 (init_iterator): Do not highlight the region of zero length.
956 (redisplay_window): Check whether the region is of non-zero length.
957 (try_cursor_movement): Allow if the region length is zero.
958 (try_window_reusing_current_matrix, try_window_id): Likewise.
960 2012-12-13 Eli Zaretskii <eliz@gnu.org>
962 * search.c (search_buffer): Check the inverse translations of each
963 character in pattern when the buffer being searched is unibyte.
966 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
968 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
969 files, fixing a regression from 24.2.
970 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.

974 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
975 fstat shouldn't fail, and if it does fail copy-file should not proceed.
976 Remove unnecessary S_ISLNK test, as (contra the comments) this
977 function can't copy symlinks. Improve quality of error message
978 when attempting to copy files that are neither regular files nor

1052 Windows file notification functionality unless WINDOWSNT.
1054 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
1057 * w32fns.c (cache_system_info): Initialize the global hinst
1058 variable here so various initialization calls DTRT.

1061 (hinst): Remove unneeded extern declaration.
1062 (_start): Remove initialization of above variables; remove

1069 Teach the autoconf build system how to compile a Windows resource file
1070 and link it to Emacs.

1174 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
1176 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
1177 DWORD_PTR, for compatibility with 64-bit builds.

1207 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1209 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).

1211 * dbusbind.c (Fdbus_init_bus):
1213 * xterm.c (x_term_init):
1214 Use xputenv instead of setenv or putenv, to detect memory exhaustion.

1221 instead, use xputenv+unsetenv to set and restore TZ.
1222 (environbuf): Remove static var. All uses removed.

1224 no longer needed here.
1225 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1226 Move to inside set_time_zone_rule; they don't need file scope any more.
1227 (set_time_zone_rule): Maintain the TZ=value string separately.
1228 (syms_of_editfns): Don't initialize initial_tz;
1229 init_editfns now does it.
1230 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
1231 * lisp.h (xputenv): New decl.
1233 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

1248 Simplify get_lim_data.
1249 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
1250 Remove USG and vlimit methods; no longer used these days.
1251 Add #error catchall just in case.
1253 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
1254 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
1255 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.

1262 (abbr_to_signal): New static function.
1263 (Fsignal_process): Use it to convert signal names to ints.

1266 (emacs_sigaction_init): Assume SIGCHLD is defined.
1267 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,

1274 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>

1277 This will cause a production Emacs to dump core instead of
1280 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1282 * frame.c (make_frame): Do not set window's buffer to t.
1283 * window.c (Fsplit_window_internal): Likewise. Previously it was
1284 used to indicate that the window is being set up. Now we use
1285 set_window_buffer for all new windows, so the condition in ...
1286 (Fset_window_buffer): ... is always true and can be removed.
1288 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1290 Convenient macro to check whether the buffer is hidden.
1291 * buffer.h (BUFFER_HIDDEN_P): New macro.
1292 * frame.c (make_frame): Use it. Adjust comment.
1293 * buffer.c (candidate_buffer): New function.
1294 (Fother_buffer, other_buffer_safely): Use it.
1296 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1298 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
1299 if the child process is still running. Instead, exit the wait
1300 loop and return zero. (Bug#13086)
1302 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1304 * frame.h (x_char_width, x_char_height): Remove prototypes.

1315 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
1317 Fix a recently-introduced delete-process race condition.
1318 * callproc.c, process.h (record_kill_process):
1319 New function, containing part of the old call_process_kill.
1320 (call_process_kill): Use it.
1321 This does not change call_process_kill's behavior.
1322 * process.c (Fdelete_process): Use record_kill_process to fix a
1323 race condition that could cause Emacs to lose track of a child.
1325 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1327 Avoid code duplication between prev_frame and next_frame.
1328 * frame.c (candidate_frame): New function. Add comment.
1329 (prev_frame, next_frame): Use it. Adjust comment.
1331 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1333 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1334 fails, signal an error instead of continuing with an empty
1336 Encode expanded temp file pattern before passing it to mkstemp or
1339 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1340 Encode the file name before passing it to dostounix_filename, in
1341 case it will downcase it (under w32-downcase-file-names).
1344 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1346 Minor call-process cleanups.
1347 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1348 at the same time as other platforms, to simplify analysis.
1349 No need for fd0_volatile since we have synch_process_fd.
1350 Avoid needless emacs_close; arg is always negative.
1352 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1354 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
1357 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
1359 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1360 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
1361 and mouse_face_hidden members to a bitfields.
1362 * frame.h (struct frame): Remove set-but-not-used space_width member.
1363 (FRAME_SPACE_WIDTH): Remove.
1364 * nsterm.m, w32term.c, xterm.c: Adjust users.
1365 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1366 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1367 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1368 members to a bitfields.
1370 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1372 Don't let call-process be a zombie factory (Bug#12980).
1373 Fixing this bug required some cleanup of the signal-handling code.
1374 As a side effect, this change also fixes a longstanding rare race
1375 condition whereby Emacs could mistakenly kill unrelated processes,
1376 and it fixes a bug where a second C-g does not kill a recalcitrant
1377 synchronous process in GNU/Linux and similar platforms.
1378 The patch should also fix the last vestiges of Bug#9488,
1379 a bug which has mostly been fixed on the trunk by other changes.
1380 * callproc.c, process.h (synch_process_alive, synch_process_death)
1381 (synch_process_termsig, sync_process_retcode):
1382 Remove. All uses removed, to simplify analysis and so that
1383 less consing is done inside critical sections.
1384 * callproc.c (call_process_exited): Remove. All uses replaced
1385 with !synch_process_pid.
1386 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1387 These take the role of what used to be in unwind-protect arg.
1389 (block_child_signal, unblock_child_signal):
1390 New functions, to avoid races that could kill innocent-victim processes.
1391 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1392 (call_process_kill): Record killed processes as deleted, so that
1393 zombies do not clutter up the system. Do this inside a critical
1394 section, to avoid a race that would allow the clutter.
1395 (call_process_cleanup): Fix code so that the second C-g works again
1396 on common platforms such as GNU/Linux.
1397 (Fcall_process): Create the child process in a critical section,
1398 to fix a race condition. If creating an asynchronous process,
1399 record it as deleted so that zombies do not clutter up the system.
1400 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1401 light of these changes. Omit unnecessary call to emacs_close
1402 before failure, as the unwind-protect code does that.
1403 * callproc.c (call_process_cleanup):
1404 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1405 * process.c (record_deleted_pid): New function, containing
1406 code refactored out of Fdelete_process.
1407 (Fdelete_process): Use it.
1408 (process_status_retrieved): Remove. All callers changed to use
1409 child_status_change.
1410 (record_child_status_change): Remove, folding its contents into ...
1411 (handle_child_signal): ... this signal handler. Now, this
1412 function is purely a handler for SIGCHLD, and is not called after
1413 a synchronous waitpid returns; the synchronous code is moved to
1414 wait_for_termination. There is no need to worry about reaping
1415 more than one child now.
1416 * sysdep.c (get_child_status, child_status_changed): New functions.
1417 (wait_for_termination): Now takes int * status and bool
1418 interruptible arguments, too. Do not record child status change;
1419 that's now the caller's responsibility. All callers changed.
1420 Reimplement in terms of get_child_status.
1421 (wait_for_termination_1, interruptible_wait_for_termination):
1422 Remove. All callers changed to use wait_for_termination.
1423 * syswait.h: Include <stdbool.h>, for bool.
1424 (record_child_status_change, interruptible_wait_for_termination):
1426 (record_deleted_pid, child_status_changed): New decls.
1427 (wait_for_termination): Adjust to API changes noted above.
1429 * bytecode.c, lisp.h (Qbytecode): Remove.
1430 No longer needed after 2012-11-20 interactive-p changes.
1432 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1434 * xdisp.c (redisplay_window): If the cursor is visible, but inside

1484 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1486 Fix xpalloc confusion after memory is exhausted.
1487 * alloc.c (xpalloc): Comment fix.
1488 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1489 and signals an error, do not clear charset_table_size, as
1490 charset_table is still valid.
1491 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1493 Use execve to avoid need to munge environ (Bug#13054).
1494 * callproc.c (Fcall_process):
1495 * process.c (create_process):
1496 Don't save and restore environ; no longer needed.
1497 * callproc.c (child_setup):
1498 Use execve, not execvp, to preserve environ.
1500 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1502 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1504 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1506 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1507 display for sliced images (Bug#10500).
1509 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.

1519 some suspicious corner cases (see Bug#13007 and Bug#13012).
1520 (mode_line_update_needed): New function.
1521 (redisplay_internal, redisplay_window): Use it.
1522 (ensure_selected_frame): New function.

1525 (buffer_shared_and_changed): ...near to its real use.
1527 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1529 * callproc.c (Fcall_process): Don't misreport vfork failure.
1531 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1533 * callproc.c (Fcall_process): Fix vfork portability problems.
1534 Do not assume that fd[0], count, filefd, and save_environ survive
1535 vfork. Fix bug whereby wrong errno value could be reported for
1536 pipe failure. Some minor cleanups, too, as follows. Move buf and
1537 bufsize to the context where they're needed. Change new_argv to
1538 be of type char **, as this is more convenient and avoids casts.
1539 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1540 Now local constants, not macros.
1542 2012-11-18 Kenichi Handa <handa@gnu.org>
1544 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1545 for the variable "f".

1549 * font.c (font_unparse_xlfd): Exclude special characters from the
1550 generating XLFD name.

1577 violations when repeatedly clicking on the "Top" link of the
1578 "bread-crumbs" in Info buffers.

1592 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1593 between bpos_covered and bpos_max. This fixes cursor display when
1594 several display strings follow each other.
1596 * .gdbinit (pgx): If the glyph's object is a string, display the
1597 pointer to string data, rather than the value of the string object
1598 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1600 * indent.c (Fvertical_motion): If the starting position is covered
1601 by a display string, return to one position before that, to avoid
1602 overshooting it inside move_it_to. (Bug#12930)
1604 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1606 * frame.h (struct frame): Remove display_preempted member

1615 Drop unused pending_menu_activation member.
1616 * xterm.h (struct x_output): Drop outdated #if 0 code.
1617 Use bitfields for explicit_parent, asked_for_visible,
1618 has_been_visible and net_wm_state_hidden_seen members.

1622 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1623 of a literal "/". (Bug#12955)
1624 (gl-stamp): Invoke fc.exe directly, not through cmd.

1629 * dired.c: Assume HAVE_DIRENT_H.
1630 (NAMLEN): Remove, replacing with ...
1631 (dirent_namelen): New function. All uses changed. Use the GNU macro
1632 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1633 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1634 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1635 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1637 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1638 * ndir.h: Rename to ../nt/inc/dirent.h.
1639 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1640 Do not include <dirent.h>; no longer needed.
1641 * w32.c: Include <dirent.h> rather than "ndir.h".
1643 2012-11-23 Chong Yidong <cyd@gnu.org>
1645 * xftfont.c (xftfont_open): Remove duplicate assignment.
1647 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1649 * alloc.c (Fgarbage_collect): Unblock input after clearing
1650 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1651 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1652 * msdos.c (IT_frame_up_to_date): Use it here...
1653 * w32term.c (w32_frame_up_to_date): ...here...
1654 * xterm.c (XTframe_up_to_date): ...and here...
1655 * nsterm.m (ns_frame_up_to_date): ...but not here.
1656 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1658 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1659 Do not check whether GC is in progress.

1663 * xdisp.c (window_buffer_changed): New function.
1664 (update_menu_bar, update_tool_bar): Use it to
1665 simplify large 'if' statements.

1669 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1671 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1672 with Windows system header.
1674 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1676 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1677 * alloc.c: Assume unistd.h exists.

1693 * emacs.c (main): Set the G_SLICE environment variable for all
1694 Cygwin builds, not just GTK builds. See
1695 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1697 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1699 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1700 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1701 Define for the MSVC compiler.
1703 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1705 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1706 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1707 dostounix_filename. Prevents crashes down the road, because
1708 dostounix_filename assumes it gets a unibyte string.
1709 Reported by Michel de Ruiter <michel@sentient.nl>, see

1741 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1742 (syms_of_eval): Remove corresponding defsubr.
1743 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1745 2012-11-19 Daniel Colascione <dancol@dancol.org>
1747 * w32fns.c (Fx_file_dialog):
1748 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1749 cygwin_convert_file_name*.
1751 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1752 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1754 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1756 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1758 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1760 * w32select.c: Include w32common.h before w32term.h, so that
1761 windows.h gets included before w32term.h uses some of its
1762 features, see below.
1764 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1766 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

1770 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1772 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1773 (ns_select): Return at once if events are held (Bug#12834).
1775 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1777 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1778 Needed following 2012-10-20 change. (Bug#12902)
1780 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1782 * w32proc.c (waitpid): Remove unused label get_result.
1784 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1786 * makefile.w32-in (SYSWAIT_H): New macro.
1787 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1788 ($(BLD)/sysdep.$(O)): Update dependencies.

1794 * emacs.c, term.c (O_RDWR): Remove.
1795 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1796 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1797 * nsterm.m: Assume <fcntl.h> exists.
1798 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1799 (create_pty, Fmake_network_process, server_accept_connection)
1800 (wait_reading_process_output, init_process_emacs):
1802 (wait_reading_process_output): Put in a special case for WINDOWSNT
1803 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1804 It's not clear this is needed, but it's a more-conservative change.
1805 (create_process): Assume FD_CLOEXEC.
1806 (create_process, create_pty): Assume O_NOCTTY.
1807 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1808 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1809 Omit if not DOS_NT, since F_GETFL is not defined there.
1810 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1811 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1813 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1814 lack it, since gnulib guarantees this.
1815 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1817 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1819 * w32.c (faccessat): Pretend that directories have the execute bit
1820 set. Emacs expects that, e.g., in files.el:cd-absolute.
1822 * w32proc.c (create_child): Don't clip the PID of the child
1823 process to fit into an Emacs integer, as this is no longer a
1825 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1826 reaping only the process specified by PID argument, if that is
1827 positive. Use PID instead of dead_child to know which process to
1828 reap. Wait for the child to die only if WNOHANG is not in
1830 (sys_select): Don't set dead_child.
1832 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1833 as it is no longer needed.
1835 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1837 (record_child_status_change): Remove the setting of
1838 record_at_most_one_child for the !WNOHANG case.
1840 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1842 Fix problems in ns port found by static checking.
1843 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1844 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1845 not to process group.
1846 (ns_select): Use emacs_write, not write, as that's more robust
1847 in the presence of signals.
1848 (fd_handler:): Check for read errors.
1850 2012-11-16 Glenn Morris <rgm@gnu.org>
1852 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1854 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1856 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1858 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1860 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1861 use the same value of thread handle.
1862 (start_timer_thread): If the timer thread exited (due to error),
1863 clean up by closing the two handles it used. Duplicate the caller
1864 thread's handle here, so it gets duplicated only once, when
1865 launching the timer thread. Set priority of the timer thread, not
1867 (getitimer): Don't duplicate the caller thread's handle here.
1870 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1872 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1875 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1877 Remove no-longer-used pty_max_bytes variable.
1878 * process.c (pty_max_bytes): Remove; unused.
1879 (send_process): Do not set it.
1881 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1883 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1884 Update dependencies.
1886 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1888 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1889 This follows up on the 2012-09-29 patch that removed indirection
1890 for the 'function' field. Reported by Sergey Vinokurov in
1891 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1893 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1895 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1896 different name, as the MS runtime does not have such a function,
1897 and probably never will.) All callers changed. Ignore DIRFD
1898 value if PATH is an absolute file name, to match Posix spec
1899 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1902 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1904 * xdisp.c (echo_area_display, redisplay_internal):
1905 Omit redundant check whether frame_garbaged is set.
1907 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1909 Use faccessat, not access, when checking file permissions (Bug#12632).
1910 This fixes a bug that has been present in Emacs since its creation.
1911 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1912 which must set some sort of record. (Torek's bug report was against
1913 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1914 same common flaw.) See Torek's Usenet posting
1915 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1916 Posted: Fri Apr 8 14:18:56 1983.
1917 * Makefile.in (LIB_EACCESS): New macro.
1919 * callproc.c (init_callproc):
1920 * charset.c (init_charset):
1921 * fileio.c (check_existing, check_executable, check_writable)
1923 * lread.c (openp, load_path_check):
1924 * process.c (allocate_pty):
1926 Use effective UID when checking permissions, not real UID.
1927 * callproc.c (init_callproc):
1928 * charset.c (init_charset):
1929 * lread.c (load_path_check, init_lread):
1930 Test whether directories are accessible, not merely whether they exist.
1931 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1932 * fileio.c (check_existing, check_executable, check_writable)
1934 Use symbolic names instead of integers for the flags, as they're
1936 (check_writable): New arg AMODE. All uses changed.
1937 Set errno on failure.
1938 (Ffile_readable_p): Use faccessat, not stat + open + close.
1939 (Ffile_writable_p): No need to call check_existing + check_writable.
1940 Just call check_writable and then look at errno. This saves a syscall.
1941 dir should never be nil; replace an unnecessary runtime check
1942 with an eassert. When checking the parent directory of a nonexistent
1943 file, check that the directory is searchable as well as writable, as
1944 we can't create files in unsearchable directories.
1945 (file_directory_p): New function, which uses 'stat' on most platforms
1946 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1947 (Ffile_directory_p, Fset_file_times): Use it.
1948 (file_accessible_directory_p): New function, which uses a single
1949 syscall for efficiency.
1950 (Ffile_accessible_directory_p): Use it.
1951 * xrdb.c (file_p): Use file_directory_p.
1952 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1953 * lread.c (openp): When opening a file, use fstat rather than
1954 stat, as that avoids a permissions race. When not opening a file,
1955 use file_directory_p rather than stat.
1956 (dir_warning): First arg is now a usage string, not a format.
1957 Use errno. All uses changed.
1958 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1959 that merely introduced a race.
1960 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1961 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1962 and similarly for the other O_* flags.
1963 * w32.c (sys_faccessat): Rename from sys_access and switch to
1964 faccessat's API. All uses changed.
1965 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1966 (magic_db): Rename from magic_file_p.
1967 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1968 char *, so that we don't have to test for file existence
1969 separately from opening the file for reading. This removes a race
1970 fixes a permission-checking problem, and simplifies the code.
1972 (file_p): Remove; no longer needed.
1974 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1976 Omit glyphs initialization at startup.
1977 * dispnew.c (glyphs_initialized_initially_p): Remove.

1979 (Fredraw_frame): Move actual code from here...
1980 (redraw_frame): ...to here. Add eassert. Adjust comment.
1981 (Fredraw_display): Use redraw_frame.
1982 * xdisp.c (clear_garbaged_frames): Likewise.
1984 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1986 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1987 passed to pint2str and pint2hrstr to be at most the size of the
1988 frame's decode_mode_spec_buffer. This avoids crashes with very
1989 large values of FIELD_WIDTH argument to decode_mode_spec.
1992 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1994 Fix a race with verify-visited-file-modtime (Bug#12863).
1995 Since at least 1991 Emacs has ignored an mtime difference of no
1996 more than one second, but my guess is that this was to work around
1997 file system bugs that were fixed long ago. Since the race is
1998 causing problems now, let's remove that code.
1999 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2000 whose time stamp is off by no more than a second. Insist that the
2001 file time stamps match exactly.
2003 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2005 * frame.h (struct frame): Convert external_tool_bar member to
2006 1-bit unsigned bitfield.
2007 * termhooks.h (struct terminal): Remove mouse_moved member since
2008 all users are long dead. Adjust comment on mouse_position_hook.
2010 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2012 Simplify by using FOR_EACH_FRAME here and there.
2013 * frame.c (next_frame, prev_frame, other_visible_frames)
2014 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2015 * w32term.c (x_window_to_scroll_bar): Likewise.
2016 * window.c (window_list): Likewise.
2017 * xdisp.c (x_consider_frame_title): Likewise.
2018 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2019 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2020 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2021 * xmenu.c (menubar_id_to_frame): Likewise.
2022 * xselect.c (frame_for_x_selection): Likewise.
2023 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2024 (x_window_to_menu_bar): Likewise.
2025 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2027 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2029 * data.c (Qdefalias_fset_function): Now static.
2031 Another tweak to vectorlike_header change.
2032 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2033 Remove, and replace all uses with ...
2034 (next_in_free_list, set_next_in_free_list):
2035 New functions, which respect C's aliasing rules better.
2037 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2039 * window.c (list4i): Rename from 'quad'. All uses changed.
2040 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2042 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2044 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2045 warning about mixing declarations and code in ISO C90.
2047 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2049 * window.c (Fsplit_window_internal): Set combination limit of
2050 new parent window to t iff Vwindow_combination_limit is t;
2051 fixing a regression introduced with the change from 2012-09-22.
2052 (Fset_window_combination_limit): Fix doc-string.
2054 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2056 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2057 amount when the scroll margins are too large. When scrolling
2058 backwards in the buffer, give up if cannot reach point or the
2059 scroll margin within a reasonable number of screen lines.
2060 Fixes point position in window under scroll-up/down-aggressively when
2061 point is positioned many lines beyond the window top/bottom.
2064 * ralloc.c (relinquish): If real_morecore fails to return memory
2065 to the system, don't crash; instead, leave the last heap
2066 unchanged and return. (Bug#12774)
2068 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2070 * lisp.h (AUTOLOADP): New macro.

2073 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2075 (Finteractive_form): Simplify.
2076 (Fquo): Don't insist on having at least 2 arguments.
2077 (Qdefalias_fset_function): New var.
2079 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2081 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

2087 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2089 Fix recently introduced crash on MS-Windows (Bug#12839).
2090 * w32term.h (struct scroll_bar): Use convenient header.
2091 (SCROLL_BAR_VEC_SIZE): Remove.
2092 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2094 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2096 Tweak last vectorlike_header change.
2097 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2098 vectorlike object on the free list. This is introduced to avoid
2099 some (but not all) pointer casting and aliasing problems, see
2100 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2101 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2103 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2105 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2107 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2108 been removed, so remove them here also.
2110 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2112 * doc.c (Fdocumentation): Handle new property
2113 dynamic-docstring-function to replace the old ad-advice-info.
2115 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2117 * fns.c (Qeql, hashtest_eq): Now static.
2119 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2121 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2122 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2123 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2124 * buffer.c (compare_overlays): Use XLI rather than XHASH.

2129 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2130 * lisp.h (sxhash_combine): New inline function, with the contents
2131 of the old SXHASH_COMBINE.
2132 * profiler.c (hashfn_profiler): Use it, instead of having a
2133 special hash function containing a comparison that always yields 1.
2135 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2137 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2138 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2139 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2142 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2144 * image.c (xpm_make_color_table_h): Fix compiler error because
2145 make_hash_table changed.

2149 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2151 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2153 Use ad-hoc comparison function for the profiler's hash-tables.
2154 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2155 (make_log): Use them.
2156 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2157 call Fequal any more.

2187 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2189 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

2205 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2206 (Fmake_bool_vector): Likewise.
2207 (struct large_vector): New type to represent allocation unit for
2208 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2209 (large_vectors): Change type to struct large_vector.
2210 (allocate_vector_from_block): Simplify.
2211 (PSEUDOVECTOR_NBYTES): Replace with...
2212 (vector_nbytes): ...new function. Adjust users.

2233 * keyboard.c (event_to_kboard): Do not dereference
2234 frame_or_window field of SELECTION_REQUEST_EVENT
2235 and SELECTION_CLEAR_EVENT events (Bug#12814).

2240 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2241 such as Scroll Lock, if the respective keys are treated as
2242 function keys, not as modifiers. This avoids destroying non-ASCII

2247 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2249 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2251 Restore some duplicate definitions (Bug#12814).
2252 This undoes part of the 2012-11-03 changes. Some people build
2253 with plain -g rather than with -g3, and they need the duplicate
2254 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2255 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2256 Define as macros, as well as as enums or as constants.

2261 to keypad keys (Bug#12816).
2263 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2265 Minor adjustments of recently-changed frame functions.
2266 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2267 known to be a frame (we're in the FRAMEP branch).
2268 * lisp.h (Qframep): Remove decl. frame.h declares this.
2269 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2270 since they're meant for Lisp fixnum values.
2272 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2274 * window.c (Fwindow_combination_limit): Revert to the only
2275 required argument and adjust docstring as suggested in
2276 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2277 by Martin Rudalics <rudalics@gmx.at>.

2328 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2330 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2331 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2332 file descriptor 2 for standard error. (Bug#12805)
2334 2012-11-05 Chong Yidong <cyd@gnu.org>
2336 * process.c (wait_reading_process_output): Revert previous change.
2338 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2340 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2341 This removes code that has been obsolete since around 1990.
2342 * callproc.c (Fcall_process):
2344 * process.c (create_process):
2345 * term.c (dissociate_if_controlling_tty):
2346 Assume setsid exists.
2347 * callproc.c (child_setup): Assume setpgid exists and behaves as
2348 per POSIX.1-1988 or later.
2349 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2350 * emacs.c (shut_down_emacs):
2351 * sysdep.c (sys_suspend, init_foreground_group):
2352 Assume getpgrp behaves as per POSIX.1-1998 or later.
2353 * msdos.c (setpgrp): Remove.
2354 (tcgetpgrp, setpgid, setsid): New functions.
2355 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2356 * term.c (no_controlling_tty): Remove; unused.
2357 * w32proc.c (setpgrp): Remove.
2358 (setsid, tcgetpgrp): New functions.
2360 Simplify by assuming __fpending.
2361 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2362 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2363 Do not assume that __fpending's result fits in int.
2365 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2367 Remove EMACS_OUTQSIZE+sleep hack.
2368 * dispnew.c (update_frame_1): Remove hack for terminals slower
2369 than 2400 bps, which throttled Emacs by having it sleep.
2370 This code hasn't worked since at least 2007, when the multi-tty stuff
2371 was added, and anyway those old terminals are long dead.
2372 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2373 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2375 Fix data-loss with --version (Bug#9574).
2376 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2377 as we can't assume that emacs_strerror is initialized, and strerror
2378 is good enough here.
2379 (main): Invoke atexit earlier, to catch earlier instances of
2380 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2382 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2384 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2385 (keyDown): Remap keypad keys to X11 virtual key codes.
2387 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2389 Fix data-loss with --batch (Bug#9574).
2390 * emacs.c: Include <close-stream.h>.
2391 (close_output_streams): New function.
2392 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2393 and handles errors appropriately.
2394 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2397 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2398 The symptom is a diagnostic "GLib-WARNING **: In call to
2399 g_spawn_sync(), exit status of a child process was requested but
2400 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2401 waitpid(), so exit status can't be returned." The diagnostic
2402 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2403 The real bug is a race condition between Emacs and glib: Emacs
2404 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2405 so that glib can't find it. Work around the bug by invoking
2406 waitpid only on subprocesses that Emacs itself creates.
2407 * process.c (create_process, record_child_status_change):
2408 Don't use special value -1 in pid field, as the caller now must
2409 know the pid rather than having the callee infer it.
2410 The inference was sometimes incorrect anyway, due to another race.
2411 (create_process): Set new 'alive' member if child is created.
2412 (process_status_retrieved): New function.
2413 (record_child_status_change): Use it.
2414 Accept negative 1st argument, which means to wait for the
2415 processes that Emacs already knows about. Move special-case code
2416 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2417 processes that have already been waited for, by testing and
2418 clearing new 'alive' member.
2419 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2420 now does this internally.
2421 (handle_child_signal): Let record_child_status_change do all
2422 the work, since we do not want to reap all exited child processes,
2423 only the child processes that Emacs itself created.
2424 * process.h (Lisp_Process): New boolean member 'alive'.
2426 Omit duplicate definitions no longer needed with gcc -g3.
2427 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2428 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2429 Define only as macros. There's no longer any need to also define
2430 these symbols as enums or as constants, since we now assume
2431 gcc -g3 when debugging.
2433 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2435 * lisp.mk: Adjust comments to the fact that term/internal is now
2436 loaded from loadup.el.
2438 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2439 (msdos_fatal_signal): New function.
2440 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2443 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2444 for GCC versions before 4.
2445 (emacs_raise): Define to call msdos_fatal_signal.
2447 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2448 iterator when starting in the middle of a display or overlay
2451 2012-11-03 Chong Yidong <cyd@gnu.org>
2453 * process.c (wait_reading_process_output): Clean up the last
2456 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2458 * process.c (wait_reading_process_output): Avoid a race condition
2459 with SIGIO delivery (Bug#11536).
2461 2012-11-03 Chong Yidong <cyd@gnu.org>
2463 * buffer.c (cursor_type): Untabify docstring.
2465 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2467 * frame.h (struct frame): Drop can_have_scroll_bars member
2468 which is meaningless for a long time. Adjust comments.
2469 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2470 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2472 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2474 * window.c (decode_next_window_args): Update window arg after
2475 calling decode_live_window and so fix crash reported at
2476 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2477 by Juanma Barranquero <lekktu@gmail.com>.
2478 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2479 * font.c (Ffont_at): Likewise.
2481 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2483 * widget.c (resize_cb): New function.
2484 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2485 (EmacsFrameResize): Check if all is up to date before changing frame
2488 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2490 Implement backtrace output for fatal errors on MS-Windows.
2491 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2492 (BACKTRACE_LIMIT_MAX): New macro.
2493 (w32_backtrace): New function.
2494 (emacs_abort): Use w32_backtrace when the user chooses not to
2495 attach a debugger. Update the text of the abort dialog.
2497 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2499 Window-related stuff cleanup here and there.
2500 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2501 Use decode_any_window.
2502 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2503 * xdisp.c (Fformat_mode_line): Likewise.
2504 * font.c (Ffont_at): Use decode_live_window.
2505 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2506 * window.c (decode_next_window_args): Likewise.
2507 (decode_any_window): Remove static.
2508 * window.h (decode_any_window): Add prototype.
2509 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2510 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2513 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2515 Remove pad from struct input_event.
2516 * termhooks.h (struct input_event): Remove padding field.
2518 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2519 member is never cons for a long time. Adjust comment.
2520 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2521 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2522 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2523 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2525 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2527 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2529 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2531 Fix crash when using Emacs as commit editor for git (Bug#12697).
2532 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2533 and it is configured in conf_post.h.
2534 (Fcall_process): Don't invoke both setsid and setpgid; the former
2535 is enough, if it exists.
2536 * callproc.c (Fcall_process, child_setup):
2537 * process.c (create_process): Use setpgid.
2538 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2540 * dispnew.c (init_display): Initialize the foreground group
2541 if we are running a tty display.
2542 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2543 * lisp.h (init_foreground_group): New decl.
2544 * sysdep.c (inherited_pgroup): New static var.
2545 (init_foreground_group, tcsetpgrp_without_stopping)
2546 (narrow_foreground_group, widen_foreground_group): New functions.
2547 (init_sys_modes): Narrow foreground group.
2548 (reset_sys_modes): Widen foreground group.
2550 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2552 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2554 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2556 * minibuf.c (read_minibuf): Restore current buffer since
2557 choose_minibuf_frame calling Fset_frame_selected_window may
2558 change it (Bug#12766).
2560 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2562 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2564 2012-10-30 Kenichi Handa <handa@gnu.org>
2566 * font.c (Ffont_at): If WINDOW is specified and it is not
2567 displaying the current buffer, signal an error.
2569 2012-10-29 Daniel Colascione <dancol@dancol.org>
2571 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2572 In preparation for fixing bug#12739, move these functions from
2575 * coding.h, coding.c: ... to here, and compile them only when
2576 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2577 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2579 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2581 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2582 (timer_loop, getitimer, setitimer): Use it instead of
2583 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2585 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2588 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2590 * nsterm.m (NO_APPDEFINED_DATA): New define.
2591 (last_appdefined_event_data): New variable
2592 (last_appdefined_event): Remove.
2593 (ns_select): Initialize t from last_appdefined_event_data instead
2594 of [last_appdefined_event data1].
2595 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2596 remove last_appdefined_event (Bug#12698).
2598 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2600 * frame.c (x_set_font): Catch internal error.
2602 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2604 Avoid overflow in w32 implementation of interval timers.
2605 When possible, for ITIMER_PROF count only times the main thread
2607 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2608 'volatile ULONGLONG' types. All the other data which was
2609 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2610 (GetThreadTimes_Proc): New typedef.
2611 (w32_get_timer_time): New function, returns a suitable time value
2613 (timer_loop): Enter critical section when accessing ULONGLONG
2614 values of the itimer_data struct, as these accesses are no longer
2615 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2616 Remove unused variable.
2617 (init_timers): Initialize s_pfn_Get_Thread_Times.
2618 (start_timer_thread): Don't assign itimer->caller_thread here.
2619 (getitimer): Assign itimer->caller_thread here.
2620 (setitimer): Always call getitimer to get the value of ticks_now.
2621 (sys_spawnve): Avoid compiler warning about format mismatch.
2623 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2625 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2626 mouse movement events if the menu bar is active. This avoids
2627 producing a busy "hour-glass" cursor by Windows if the mouse
2628 pointer is positioned over a tooltip shown for some menu item.
2630 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2632 Don't assume process IDs fit in int.
2633 * emacs.c (shut_down_emacs) [!DOS_NT]:
2634 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2635 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2636 Use pid_t, not int, to store process IDs, as 'int'
2637 is not wide enough on a few platforms (e.g., AIX and IRIX).
2639 2012-10-23 Kenichi Handa <handa@gnu.org>
2641 The following change is to make face-font-rescale-alist work
2642 correctly for non-ASCII fonts.
2644 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2645 (font_open_for_lface): Handle Vface_font_rescale_alist.
2647 2012-10-23 Chong Yidong <cyd@gnu.org>
2649 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2651 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
2653 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
2655 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2657 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2660 2012-10-21 Glenn Morris <rgm@gnu.org>
2662 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2664 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2666 Port to OpenBSD 5.1.
2667 * frame.c (Fmouse_position, Fmouse_pixel_position):
2668 * xdisp.c (produce_stretch_glyph):
2669 Declare local vars only when they're needed.
2670 This is clearer and avoids a warning on OpenBSD about unused vars.
2671 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2672 This is safer, and avoids OpenBSD warnings about unused vars.
2673 * keyboard.c (record_menu_key): Remove unnecessary decl.
2674 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2675 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2676 as our definition clashes with OpenBSD's.
2677 * xfaces.c (load_face_colors, check_lface_attrs)
2678 (get_lface_attributes_no_remap, get_lface_attributes)
2679 (lface_fully_specified_p, x_supports_face_attributes_p)
2680 (tty_supports_face_attributes_p, face_fontset, realize_face)
2681 (realize_x_face, realize_tty_face):
2682 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2683 merely Lisp_Object *. This is more informative and avoids
2684 a warning on OpenBSD about accessing beyond an object's size.
2686 2012-10-20 Chong Yidong <cyd@gnu.org>
2688 * lread.c (Fload): Doc fix (Bug#12592).
2690 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2692 * font.c (Ffont_at): Fix previous change.
2694 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2696 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2697 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
2700 * alloc.c (NSTATICS): Decrease to 0x800.
2702 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
2704 * fns.c (Fnreverse): Include the problem element when signaling an
2707 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
2709 * nsterm.m (ns_select): Check writefds before call to
2710 FD_ISSET (Bug#12668).
2712 2012-10-18 Daniel Colascione <dancol@dancol.org>
2714 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2715 (staticpro): If we run out of staticpro slots, die with an
2716 informative error instead of just calling emacs_abort.
2718 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2720 Fix two flaws reported by Dmitry Antipov.
2721 * window.c (Ftemp_output_buffer_show): Remove.
2722 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
2723 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
2725 2012-10-17 Eli Zaretskii <eliz@gnu.org>
2727 * makefile.w32-in ($(BLD)/w32.$(O)):
2728 ($(BLD)/vm-limit.$(O)):
2730 ($(BLD)/unexw32.$(O)):
2731 ($(BLD)/fileio.$(O)):
2732 ($(BLD)/dispnew.$(O)): Update dependencies.
2734 * w32term.h (w32_initialize_display_info, initialize_w32_display):
2737 * w32proc.c: Include ctype.h.
2739 * w32.h (init_environment, check_windows_init_file)
2740 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
2741 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
2742 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
2743 (sys_link): Add prototypes.
2745 * w32.c: Include w32select.h.
2746 (sys_access, e_malloc, sys_select): Add prototypes.
2747 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
2749 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
2751 * unexw32.c: Include lisp.h and w32.h.
2753 * term.c [WINDOWSNT]: Include w32term.h.
2755 * process.c [WINDOWSNT]: Add prototype of sys_select.
2757 * fileio.c [WINDOWSNT]: Include w32.h.
2759 * dispnew.c [WINDOWSNT]: Include w32.h.
2761 * cygw32.c (Fcygwin_convert_path_to_windows)
2762 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
2763 Lisp_Object values. (Bug#12661)
2765 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
2766 to Lisp_Object. (Bug#12661)
2768 2012-10-17 Kenichi Handa <handa@gnu.org>
2770 * xdisp.c (reseat_1): Make the information stored in it->cmp_it
2773 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
2775 * buffer.c (Fkill_buffer): When unchaining the marker,
2776 reset its buffer pointer to NULL (Bug#12652).
2778 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
2780 Do not verify indirection counters of killed buffers (Bug#12579).
2781 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
2782 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.
2784 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
2786 * alloc.c (Fmake_byte_code): Fix typo in comment.
2787 * print.c (print_interval): Define as static to match prototype.
2788 * indent.c (disptab_matches_widthtab, recompute_width_table):
2791 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
2793 * editfns.c (get_system_name): Remove.
2794 * lisp.h (get_system_name): Remove prototype.
2795 * xrdb.c (getenv, getpwuid, getpwnam): Remove prototypes.
2796 (get_environ_db): Use Vsystem_name. Avoid call to strlen.
2798 2012-10-15 Daniel Colascione <dancol@dancol.org>

2817 * image.c (init_tiff_functions, init_imagemagick_functions)
2818 (init_svg_functions): Fix cygw32 build break by using these
2819 functions only when WINDOWSNT _and_ HAVE_NTGUI.

2841 * fileio.c (Fwrite_region): Avoid race condition if a file is
2842 removed or renamed by some other process immediately after Emacs
2843 writes it but before Emacs stats it. Do not assume that stat (or

2872 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
2874 * fileio.c (check_existing): New function.
2875 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
2876 instead of calling 'stat', when what's needed is to check whether
2877 a file exists. This avoids expensive system calls on MS-Windows.
2880 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
2882 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

2887 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
2889 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

2931 * marker.c (cached_modiff): EMACS_INT, not int.
2933 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
2934 instead of having a wrong decl.

2970 Use bool for boolean.
2971 * keyboard.c (timers_run, swallow_events)
2972 (detect_input_pending_run_timers):
2973 * process.c (wait_reading_process_output):
2974 Use unsigned for counter where wraparound-on-overflow is desired,
2975 since unsigned is guaranteed to have that behavior and signed is not.
2976 (read_char): Use ptrdiff_t for string length.
2977 (get_input_pending): Remove first argument, since it was always
2978 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2979 and behave as if it had that value. Return new value of
2980 input_pending. All callers changed.
2981 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2982 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
2984 * keymap.c (push_key_description): Omit last arg, which was always 1.
2985 All callers changed.
2987 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
2989 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

3005 Don't include termopts.h.
3007 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
3009 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3011 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3013 * commands.h (immediate_quit): Remove duplicate decl.
3015 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3017 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

3020 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3022 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3024 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3025 match what GetLastError returns. Explain why the function is
3028 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3029 'is_tooltip_frame', to avoid confusion with its global namesake.
3031 2012-10-08 Daniel Colascione <dancol@dancol.org>
3033 * xdisp.c (start_hourglass): Call w32_note_current_window when
3034 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3035 build that caused Emacs to display the hourglass cursor forever.
3037 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3038 which is broken under remote desktop, calculate the number of
3039 colors available for a display based on the display's number of
3040 planes and number of bits per pixel per plane. (bug#10397).
3042 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3044 * nsfont.m (Vfonts_in_cache): New variable.
3045 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3046 are used. Add cached fonts to Vfonts_in_cache.
3047 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3049 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3051 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3053 (FONT_H): Define after FRAME_H.
3054 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3055 Update dependencies.
3057 * w32term.c: Remove leftover declaration of keyboard_codepage.
3059 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3061 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3062 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3063 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3064 (GLOBAL_SOURCES): Add cygw32.c.
3065 ($(BLD)/unexw32.$(O)):
3067 ($(BLD)/w32console.$(O)):
3068 ($(BLD)/w32fns.$(O)):
3069 ($(BLD)/w32heap.$(O)):
3070 ($(BLD)/w32menu.$(O)):
3071 ($(BLD)/w32proc.$(O)): Add w32common.h.
3073 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3075 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3077 2012-10-08 Daniel Colascione <dancol@dancol.org>
3079 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3080 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3081 accidental message numbering hole. Change other messages to
3084 * w32select.h (HAVE_W32SELECT): Remove.
3086 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3087 w32common.h instead of w32heap.h.
3089 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3090 (get_allocation_unit, get_processor_type, get_w32_major_version)
3091 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3092 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3093 (OS_NT, os_subtype, cache_system_info): Move declarations to
3096 * w32heap.c: Include w32common.h.
3097 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3098 (w32_minor_version, w32_build_number, w32_subtype):
3099 Remove duplicate definitions.
3101 * w32fns.c: Include w32common.h; include w32heap.h only in
3104 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3105 Use `report_file_error' instead of `error' in order to better
3106 inform users of what went wrong. Increase NTGUI_UNICODE file
3107 dialog box file name length to 32k, the maximum allowed by the NT
3110 * w32common.h: New file.
3111 (ROUND_UP, ROUND_DOWN, get_page_size)
3112 (get_allocation_unit, get_processor_type, get_w32_major_version)
3113 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3114 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3115 (OS_NT, os_subtype, cache_system_info): Move here.
3117 * unexw32.c, unexcw.c: Include w32common.h.
3119 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3120 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3121 to call syms_of_w32select.
3123 * cygw32.h: Remove obsolete EXFUN declarations.
3125 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

3128 of w32inevt.o from SOME_MACHINE_OBJECTS.
3130 2012-10-08 Daniel Colascione <dancol@dancol.org>
3132 * image.c: Permanent fix for JPEG compilation issue --- limit
3133 jpeglib `boolean' redefinition to Cygwin builds.
3135 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3137 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3139 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3142 2012-10-08 Daniel Colascione <dancol@dancol.org>
3144 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3145 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3146 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3147 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3148 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3149 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3150 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3151 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3152 now a supported configuration.
3154 * Makefile.in: consolidate image variables into LIBIMAGE; add
3155 W32_OBJ and W32_LIBS. Compile new files.
3158 (_DebPrint) declare tracing facility for W32 debugging. We need
3159 to unify tracing later.
3161 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3162 unconditional use of W32 Unicode functions. Cygwin runs only on
3163 100% Unicode operating systems.
3165 * cygw32.c: New file. Define Cygwin-specific facilities.
3166 (Fcygwin_convert_path_to_windows)
3167 (Fcygwin_convert_path_from_windows): New user functions for
3168 accessing Cygwin path-munging routines.
3170 * cygw32.h: New file.
3171 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3172 UTF-16LE strings temporarily inside non-Lisp-visible string
3175 (w32_strerror): Just what it says on the tin.
3177 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3178 also run for Cygwin; both systems have the same problem with using
3179 GUI facilities in a forked child. Also call syms_of_cygw32,
3180 syms_of_w32select in correct places.
3182 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3183 needs fork-then-exec for daemon launching.
3185 * font.h: Include frame.h.
3187 * image.c: Use the image library cache machinery only when we're
3188 compiling for native WINDOWSNT; Cygwin can use shared libraries
3189 like any other Unixlike system.
3191 * keyboard.c: Clarify a comment regarding the input loop.
3193 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3194 functions directly instead of trying to detect at runtime that our
3195 host operating system supports them. We make this change for two
3196 reasons: Cygwin lacks support for the multibyte character
3197 conversion functions used by the legacy menu code, and Cygwin
3198 never needs to rely on non-Unicode APIs.
3200 * unexw32.c (hinst): Declare extern.
3202 * w32.c: Change header order;
3203 (w32_strerror): Move to w32fns.c because we need it for
3204 non-WINDOWSNT builds.
3206 * w32.h: Add #error macro to make sure we don't include w32.h for
3207 Cygwin builds. Remove w32select declarations.
3209 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3210 w32fns.c. w32console.c is WINDOWSNT-only.
3212 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3213 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3215 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3216 (w32_major_version, w32_minor_version, w32_build_number)
3217 (os_subtype, sound_type): Define here
3218 (w32_defined_color): Make color parameter const for consistency
3219 with other _defined_color functions.
3220 (w32_createwindow): Unconditionally call w32_init_class instead of
3221 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3222 through the code is complex and unnecessary because class
3223 registration is practically free.
3224 (w32_name_of_message): New EMACSDEBUG-only function.
3225 (Fset_message_beep): Move here
3226 (Fx_open_connection): Require that the display name for Windows be
3227 "w32" for consistency, emacsclient disambiguation, and maybe, one
3228 day, multi-window-system support.
3229 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3230 Cygwin files for W32 GUI facilities, since these clearly don't
3231 expect Cygwin names.
3232 (_DebPrint): Define.
3233 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3234 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3235 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3236 (w32_last_error): Remove.
3238 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3240 * w32heap.c (syspage_mask): Declare here.
3241 (cache_system_info): Remove.
3243 * w32inevt.c (faked_key): Define globally, not statically.
3244 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3245 (w32_console_toggle_lock_key): Move to w32fns.c.
3247 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3249 * w32proc.c (_DebPrint): Move to w32fns.c.
3250 * w32select.c: Include string.h, stdio.h for Cygwin.
3251 * w32select.h: New File.
3253 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3255 (w32_message_fd): New variable. Under Cygwin, holds the file
3256 descriptor the system used to tell us about pending thread
3259 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3260 that prevented compilation under non-WINDOWSNT systems.
3262 (w32_initialize): Open /dev/windows and assign it to
3263 w32_message_fd. Provide w32 feature.
3265 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3266 (WM_EMACS_INPUT_READY): add.
3267 (prepend_msg, w32_message_fd): Declare globally.
3270 (keyboard_handle): Use only when WINDOWSNT.
3271 (notify_msg_ready): New function. Posts a message to the main
3272 thread's message queue under CYGWIN, which wakes up the main
3273 thread from select(2) by making the /dev/windows file descriptor
3274 ready. Under WINDOWSNT, it sets an event the same way the old
3277 (post, prepend_msg): Actually call notify_msg_ready instead of
3278 setting the input event directly.
3280 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3282 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3283 but it still has blocs in it, don't return it to the system,
3284 instead of aborting. (Bug#12402)
3286 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3288 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).

3319 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3321 Improve sys_siglist detection.
3322 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3323 defined as a macro, as is done in Solaris.
3324 (sys_siglist_entries): New macro.
3325 (save_strsignal): Use it.
3326 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3327 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3329 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3331 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3332 fullscreen/Fullscreen.
3334 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3335 tobar_height is new.
3337 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3338 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3339 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

3348 (canBecomeMainWindow): New function.
3350 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3352 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3354 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3356 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3358 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3359 that time stamps of directories could also be changed.
3360 Don't request the too broad GENERIC_WRITE, only the more restrictive
3361 FILE_WRITE_ATTRIBUTES access rights.
3363 * fileio.c (Fset_file_times): Special-case ignoring errors for
3364 directories only on MSDOS, not on MS-Windows.
3366 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3368 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3370 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3372 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3373 see whether CreateFile failed.
3375 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3377 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3378 to avoid similar races.
3379 * keyboard.c (pending_signals): Now bool, not int.
3381 Port timers to OpenBSD, plus check for timer failures.
3382 OpenBSD problem reported by Han Boetes.
3383 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3385 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3386 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3387 like OpenBSD, which has timer_settime but does not declare it.
3388 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3389 whether to use itimerspec-related primitives. All uses of
3390 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3392 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3394 * profiler.c (handle_profiler_signal): Fix a malloc race
3395 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3397 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3399 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3401 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3403 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3404 consistent with the change in return value of 'safe_strsignal'.
3406 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3408 Prefer plain 'static' to 'static inline' (Bug#12541).
3409 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3410 (bidi_set_sor_type, bidi_push_embedding_level)
3411 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

3416 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3417 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3418 Now 'static', not 'static inline'.
3420 Count overruns when profiling; change units to ns.
3421 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3422 Give extra weight to samples after overruns, to attempt to count
3423 the time more accurately.
3424 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3425 the underlying primitives nominally do ns.
3426 (Fprofiler_cpu_start): Document the change. Mention that
3427 the sampling intervals are only approximate.
3429 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3431 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3433 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3434 case for the special 0 coding-system.
3436 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3437 (Fmake_overlay): Remove redundant tests.
3438 (fix_start_end_in_overlays): Remove redundant recentering.
3440 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3442 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3443 Update dependencies.
3445 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3447 Fix a malloc race condition involving strsignal.
3448 A signal can arrive in the middle of a malloc, and Emacs's signal
3449 handler can invoke strsignal, which can invoke malloc, which is
3450 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3451 Fix it by altering the signal handler so that it does not invoke
3453 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3454 * process.c (status_message): Use const pointer, in case strsignal
3455 is #defined to safe_strsignal.
3456 * sysdep.c (sys_siglist, init_signals): Always define and
3457 initialize a substitute sys_siglist if the system does not define
3458 one, even if HAVE_STRSIGNAL.
3459 (safe_strsignal): Rename from strsignal. Always define,
3460 using sys_siglist. Return a const pointer.
3461 * syssignal.h (safe_strsignal): New decl.
3462 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3464 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3466 * w32proc.c (timer_loop): Fix code that waits for timer
3467 expiration, to avoid high CPU usage.
3469 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3471 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3472 (sweep_weak_table): Remove redundant prototypes.
3474 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3476 * emacs.c: Move the inclusion of TERM_HEADER after including
3477 windows.h on WINDOWSNT. This avoids compilation problems with
3480 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3482 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3483 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3484 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3485 as the previous version used 'void *'.
3487 * ralloc.c (ROUNDUP): Fix last change.
3488 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3491 * w32proc.c <disable_itimers>: New static flag.
3492 (init_timers): Initialize it to zero, after creating the critical
3493 sections used by the timer threads.
3494 (term_timers): Set to 1 before deleting the critical sections.
3495 (getitimer, setitimer): If disable_itimers is non-zero, return an
3496 error indication without doing anything. Reported by Fabrice
3497 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3498 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3500 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3503 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3504 term_ntproc after all the other bookkeeping, to get timers working
3505 as long as possible.
3507 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3509 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3510 Suggested by Juri Linkov in
3511 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3513 Prefer plain 'static' to 'static inline' (Bug#12541).
3514 With static functions, modern compilers inline pretty well by
3515 themselves; advice from programmers often hurts as much as it helps.
3516 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3517 this change shrinks the text size of the Emacs executable by 1.1%
3518 without affecting CPU significantly in my benchmark.
3519 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3599 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3601 Revert the FOLLOW-SYMLINKS change for file-attributes.
3602 Doing it right would require several changes to Tramp, and there's
3603 not enough time to get that tested before the freeze today.
3604 * dired.c (directory_files_internal, Ffile_attributes):
3607 * frame.c (x_report_frame_params): Port better to wider ints.
3608 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3609 or that pointers can be printed in 15 decimal digits.
3610 Avoid GCC warnings if EMACS_UINT is wider than a pointer.
3612 2012-09-30 Fabrice Popineau <fabrice.popineau@supelec.fr>

3646 * vm-limit.c (lim_data): Now size_t.
3647 (check_memory_limits): Adjust prototypes of real_morecore and
3648 __morecore to receive argument of type ptrdiff_t. Use size_t for

3790 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
3791 Suggested by Eli Zaretskii in
3792 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
3794 2012-09-30 Eli Zaretskii <eliz@gnu.org>
3796 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
3797 HAVE_TIMER_SETTIME is defined.

3801 Profiler improvements: more-accurate timers, overflow checks.
3802 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
3803 signal.h, setjmp.h. Include systime.h instead.
3804 (saturated_add): New function.
3805 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
3806 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.

3809 (enum profiler_cpu_running): New enum.
3810 (profiler_cpu_running): Now of that enum type, not bool.
3811 All uses changed to store the new value.
3812 (handle_profiler_signal): Rename from sigprof_handler_1,
3813 for consistency with other handlers. Do not check whether
3814 cpu_log is a hash-table if garbage collecting, since it
3815 doesn't matter in that case.

3817 for consistency with other handlers.
3818 (setup_cpu_timer): New function, with much of what used to be in
3819 Fprofiler_cpu_start. Check for out-of-range argument.
3820 Prefer timer_settime if available, and prefer
3821 thread cputime clocks, then process cputime clocks, then
3822 monotonic clocks, to the old realtime clock. Use make_timeval
3823 to round more-correctly when falling back to setitimer.
3824 (Fprofiler_cpu_start): Use it.
3825 (Fprofiler_cpu_stop): Prefer timer_settime if available.
3826 Don't assume that passing NULL as the 2nd argument of setitimer

3829 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
3830 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
3831 non-fatal signal handlers. Ignore SIGPROF on startup.
3832 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
3833 in profiler.c, since sysdep.c now uses it.
3835 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
3836 Suggested by Eli Zaretskii in
3837 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

3890 * charset.c, charset.h (maybe_unify_char): Now static.
3891 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
3892 Since this stuff is now private to charset.c, there's no need for
3893 a public macro and no need to inline by hand.

3926 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>

3965 (sigaction): Rewrite to call sys_signal instead of duplicating its
3967 (sys_kill): Improve commentary.
3969 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3970 consistency with a signature of a signal handler. All callers
3972 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3973 install term_ntproc as a signal handler for SIGABRT, as that
3974 should be done by the dumped Emacs.
3976 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
3978 * w32select.c (term_w32select): Protect against repeated
3979 invocation by setting clipboard_owner to NULL after calling

4097 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4098 fatal_error_backtrace.
4100 * w32proc.c (sys_kill): Undo last change: don't do anything when

4151 Avoid recursive loop if there's a fatal error in the function itself.
4152 * atimer.c (pending_atimers):
4153 * blockinput.h: Don't include "atimer.h"; no longer needed.
4154 (interrupt_input_pending): Remove. All uses removed.
4155 pending_signals now counts both atimers and ordinary interrupts.
4156 This is less racy than having three separate pending-signal flags.
4157 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4159 Rename from their upper-case counterparts BLOCK_INPUT,
4160 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4161 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4162 This makes it easier to access volatile variables more accurately.
4163 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4164 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4165 that's more reliable if the code is buggy and sets
4166 interrupt_input_blocked to a negative value. All uses changed.
4167 * atimer.c (deliver_alarm_signal):
4168 Remove. No need to deliver this to the parent; any thread can
4169 handle this signal now. All uses replaced by underlying handler.
4170 * atimer.c (turn_on_atimers):
4171 * dispnew.c (handle_window_change_signal):
4172 * emacs.c (handle_danger_signal):
4173 * keyboard.c (kbd_buffer_get_event):
4174 Don't reestablish signal handler; not needed with sigaction.
4175 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4177 Rework to avoid unnecessary accesses to volatile variables.
4178 (UNBLOCK_INPUT_TO): Now a function.
4179 (totally_unblock_input, unblock_input): New decls.
4180 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4181 (init_data): Remove. Necessary stuff now done in init_signal.
4182 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4183 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4184 (fatal_error_code): Remove; no longer needed.
4185 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4186 it doesn't always backtrace. All uses changed. No need to reset
4187 signal to default, since sigaction and/or die does that for us now.
4188 Use emacs_raise (FOO), not kill (getpid (), FOO).
4189 (main): Check more-accurately whether we're dumping.
4190 Move fatal-error setup to sysdep.c
4191 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4192 * gtkutil.c (xg_get_file_name, xg_get_font):
4193 Remove no-longer-needed signal-mask manipulation.
4194 * keyboard.c, process.c (POLL_FOR_INPUT):
4195 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4196 * keyboard.c (read_avail_input): Remove.
4197 All uses replaced by gobble_input.
4198 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4199 (kbd_buffer_store_event_hold, gobble_input):
4200 (record_asynch_buffer_change) [USABLE_SIGIO]:
4201 (store_user_signal_events):
4202 No need to mess with signal mask.
4203 (gobble_input): If blocking input and there are terminals, simply
4204 set pending_signals to 1 and return. All hooks changed to not
4205 worry about whether input is blocked.
4206 (process_pending_signals): Clear pending_signals before processing
4207 them, in case a signal comes in while we're processing.
4208 By convention callers now test pending_signals before calling us.
4209 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4210 New functions, to support changes to blockinput.h.
4211 (handle_input_available_signal): Now extern.
4212 (reinvoke_input_signal): Remove. All uses replaced by
4214 (quit_count): Now volatile, since a signal handler uses it.
4215 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4216 All callers changed. Block SIGINT only if not already blocked.
4217 Clear sigmask reliably, even if Fsignal returns, which it can.
4218 Omit unnecessary accesses to volatile var.
4219 (quit_throw_to_read_char): No need to restore sigmask.
4220 * keyboard.c (gobble_input, handle_user_signal):
4221 * process.c (wait_reading_process_output):
4222 Call signal-handling code rather than killing ourselves.
4223 * lisp.h: Include <float.h>, for...
4224 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4225 (pending_signals): Now volatile.
4226 (syms_of_data): Now const if IEEE floating point.
4227 (handle_input_available_signal) [USABLE_SIGIO]:
4228 (terminate_due_to_signal, record_child_status_change): New decls.
4229 * process.c (create_process): Avoid disaster if memory is exhausted
4230 while we're processing a vfork, by tightening the critical section
4232 (send_process_frame, process_sent_to, handle_pipe_signal)
4233 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4235 (send_process): No need for setjmp/longjmp any more, since the
4236 SIGPIPE stuff is now gone. Instead, report an error if errno
4238 (record_child_status_change): Now extern. PID and W are now args.
4239 Return void, not bool. All callers changed.
4240 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4241 Remove. All uses removed. This bug should be fixed now in a
4243 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4244 and record the child status change directly. This avoids the
4245 need to futz with the signal mask.
4246 (process_fatal_action): Move here from emacs.c.
4247 (emacs_sigaction_flags): New function, containing
4248 much of what used to be in emacs_sigaction_init.
4249 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4250 caught by emacs, to make races less likely.
4251 (deliver_process_signal): Rename from handle_on_main_thread.
4253 (BACKTRACE_LIMIT_MAX): Now at top level.
4254 (thread_backtrace_buffer, threadback_backtrace_pointers):
4256 (deliver_thread_signal, deliver_fatal_thread_signal):
4257 New functions, for more-accurate delivery of thread-specific signals.
4258 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4259 (deliver_arith_signal): Handle in this thread, not
4260 in the main thread, since it's triggered by this thread.
4261 (maybe_fatal_sig): New function.
4262 (init_signals): New arg DUMPING so that we can be more accurate
4263 about whether we're dumping. Caller changed.
4264 Treat thread-specific signals differently from process-general signals.
4265 Block all signals while handling fatal error; that's safer.
4266 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4268 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4269 Ignore SIGPIPE unless batch.
4270 (emacs_backtrace): Output backtrace for the appropriate thread,
4271 which is not necessarily the main thread.
4272 * syssignal.h: Include <stdbool.h>.
4273 (emacs_raise): New macro.
4274 * xterm.c (x_connection_signal): Remove; no longer needed
4275 now that we use sigaction.
4276 (x_connection_closed): No need to mess with sigmask now.
4277 (x_initialize): No need to reset SIGPIPE handler here, since
4278 init_signals does this for us now.
4280 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4282 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4283 background rect may be larger (Bug#12245).
4285 2012-09-23 Chong Yidong <cyd@gnu.org>
4287 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4289 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4291 * .gdbinit: Just stop at fatal_error_backtrace.
4292 See Stefan Monnier's request in
4293 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4294 Remove no-longer-used query of system type.
4296 2012-09-22 Chong Yidong <cyd@gnu.org>
4298 * search.c (Freplace_match): Doc fix (Bug#12325).
4300 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4302 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4303 (Fline_end_position): Doc fix.
4305 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4307 2012-09-22 Chong Yidong <cyd@gnu.org>
4309 * dispextern.h (struct image_type): Add new slot, storing a type
4310 initialization function.
4312 * image.c (define_image_type): Call the image initializer function
4313 if it is defined. Arguments and return value changed.
4314 (valid_image_p, make_image): Callers changed.
4315 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4316 (gif_type, imagemagick_type, svg_type, gs_type):
4317 Add initialization functions.
4318 (Finit_image_library): Call lookup_image_type.
4319 (CHECK_LIB_AVAILABLE): Macro deleted.
4320 (lookup_image_type): Call define_image_type here, rather than via
4321 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4322 (syms_of_image): Move define_image_type calls for xbm_type and
4323 pbm_type to lookup_image_type.
4325 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4327 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4328 'idle_timers' from here ...
4329 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4330 lists, to avoid infloops when the timer does something stupid,
4331 like reinvoke itself with the same or smaller time-out.
4334 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4336 * window.c (Fsplit_window_internal): Handle only Qt value of
4337 Vwindow_combination_limit separately.
4338 (Qtemp_buffer_resize): New symbol.
4339 (Vwindow_combination_limit): New default value.
4342 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4344 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4345 the new overlay string. (Bug#10159)
4347 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4349 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4350 or that fprintf is async-signal-safe. POSIX doesn't require
4353 2012-09-22 Chong Yidong <cyd@gnu.org>
4355 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4358 2012-09-22 Kenichi Handa <handa@gnu.org>
4360 * composite.c (composition_reseat_it): Handle the case that a
4361 grapheme cluster is not covered by a single font (Bug#12352).
4363 2012-09-21 Chong Yidong <cyd@gnu.org>
4365 * image.c (define_image_type): Avoid adding duplicate types to
4366 image_types (Bug#12463). Suggested by Jörg Walter.
4368 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4370 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4371 (print_load_command_name): Add case LC_DATA_IN_CODE.
4372 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4374 2012-09-21 Glenn Morris <rgm@gnu.org>
4376 * eval.c (Frun_hook_with_args_until_success)
4377 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4379 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4381 * fileio.c (Ffile_selinux_context): Only call freecon when
4382 lgetfilecon succeeded.
4383 (Fset_file_selinux_context): Likewise. (Bug#12444)
4385 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4387 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4388 reordering, locate the cursor by calling set_cursor_from_row; if
4389 that fails, clear the desired glyph matrix before returning a
4390 failure indication to the caller. Fixes leaving garbled display
4391 when fast scrolling with a down-key. (Bug#12403)
4392 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4393 scrolling through multibyte text.
4395 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4397 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4398 calling mark_vectorlike since that's the one that marks the window.
4399 (mark_discard_killed_buffers): Mark the final cdr.
4400 * window.h (struct window): Move prev/next_buffers to the
4401 non-standard fields.
4402 * window.c (make_window): Initialize prev/next_buffers manually.
4404 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4406 Omit unused arg EXPECTED from socket hooks.
4407 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4408 * nsterm.m (ns_term_init):
4409 * termhooks.h (struct terminal.read_socket_hook):
4410 * w32inevt.c (w32_console_read_socket):
4411 * w32term.c (w32_read_socket):
4412 * xterm.c (XTread_socket):
4413 Omit unused arg EXPECTED. All callers changed.
4414 (store_user_signal_events): Return void, not int, since callers no
4415 longer care about the return value. All uses changed.
4417 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4419 * w32gui.h (XParseGeometry): Do not declare.
4421 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4423 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4424 Ignore 'expected'. See Eli Zaretskii in
4425 <http://bugs.gnu.org/12471#8> (last line).
4427 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4428 (XParseGeometry): Now static. Substitute extremal values for
4429 values that are out of range.
4431 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4433 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4435 * nsfns.m (XParseGeometry): Remove.
4436 (Fx_create_frame): Call x_set_offset to correctly interpret
4437 top_pos in geometry.
4439 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4440 (Fx_parse_geometry): If there is a space in string, call
4441 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4443 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4445 * search.c (scan_buffer): Use character positions in calls to
4446 region_cache_forward and region_cache_backward, not byte
4447 positions. (Bug#12196)
4449 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4450 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4452 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4453 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4454 emacs_blocked_malloc, now deleted.
4456 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4458 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4459 The workaround was for improving performance on Solaris 2.4, but
4460 is getting in the way now. Emacs will still work if someone is
4461 still running Solaris 2.4 in a museum somewhere; Sun dropped
4462 support for Solaris 2.4 in 2003.
4463 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4464 * process.c (create_process) [HAVE_WORKING_VFORK]:
4465 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4466 since Emacs no longer uses vfork on that platform.
4468 2012-09-17 Glenn Morris <rgm@gnu.org>
4470 * emacs.c: Use COPYRIGHT.
4472 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4474 Remove configure's --without-sync-input option (Bug#12450).
4475 When auditing signal-handling in preparation for cleaning it up,
4476 I found that SYNC_INPUT has race conditions and would be a real
4477 pain to fix. Since it's an undocumented and deprecated
4478 configure-time option, now seems like a good time to remove it.
4479 Also see <http://bugs.gnu.org/11080#16>.
4480 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4481 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4482 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4483 (malloc_hysteresis):
4484 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4485 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4486 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4487 (dont_register_blocks, bytes_used_when_reconsidered)
4488 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4489 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4490 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4491 Remove. All uses removed.
4492 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4493 implementation, one that depends on whether the new macro
4494 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4496 * atimer.c (run_timers, handle_alarm_signal):
4497 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4498 (handle_async_input, process_pending_signals)
4499 (handle_input_available_signal, init_keyboard):
4500 * nsterm.m (ns_read_socket):
4501 * process.c (wait_reading_process_output):
4502 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4503 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4505 * xterm.c (XTread_socket):
4507 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4508 * eval.c (handling_signal): Remove. All uses removed.
4509 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4510 All uses replaced with the SYNC_INPUT version.
4511 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4513 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4516 * font.c (Ffont_shape_gstring): Remove unused local.
4518 2012-09-16 Glenn Morris <rgm@gnu.org>
4520 * Makefile.in (clean): No longer run nextstep's clean.
4522 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4524 (ns-app): Move here from ns.mk, and simplify.
4525 (clean): Simplify nextstep entry.
4526 * ns.mk: Remove file.
4528 2012-09-17 Kenichi Handa <handa@gnu.org>
4530 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4531 not covert the last few charactes.
4533 2012-09-16 Kenichi Handa <handa@gnu.org>
4535 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4536 here, but just check the validity of glyphs in the glyph-string.
4538 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4540 * window.c (Fwindow_parameter, Fset_window_parameter):
4541 Accept any window as argument (Bug#12452).
4543 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4545 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4546 to ns_term_init to avoid memory leak.
4548 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4549 explicit retain/release.
4550 (ns_term_init): Only allow one display. Initialize outerpool and
4553 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4555 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4556 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4557 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4558 the Microsoft problem in a different way, by altering ../nt/config.nt.
4560 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4575 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4576 by lisp.h. This completes removal of setjmp.h inclusion
4577 erroneously announced in the previous commit. (Bug#12446)
4579 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4582 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4583 not defined as a macro. The latter happens on MS-Windows.
4586 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4588 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4589 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4590 Some instances of '#include <setjmp.h>' removed, if the
4591 only reason for the instance was because "lisp.h" was included.
4592 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4593 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4594 and _longjmp with the new symbols. Emacs already uses _setjmp if
4595 available, so this change affects only POSIXish hosts that have
4596 sigsetjmp but not _setjmp, such as some versions of Solaris and
4597 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4598 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4599 (png_load_body) [HAVE_PNG]:
4600 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4601 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4602 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4603 since PNG requires jmp_buf. This is the only exception to the
4604 general rule that we now use sys_setjmp and sys_longjmp.
4605 This exception is OK since this code does not change the signal
4606 mask or longjmp out of a signal handler.
4608 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4610 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4611 Include "syssignal.h", for 'main_thread'.
4613 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4615 Avoid out-of-range marker position (Bug#12426).
4616 * insdel.c (replace_range, replace_range_2):
4617 Adjust markers before overlays, as suggested by comments.
4618 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4619 Remove redundant check before calling offset_intervals.
4621 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4623 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4624 current buffer (Bug#12387).
4626 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4628 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4630 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4632 Use a more backwards-compatible timer format (Bug#12430).
4633 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4634 vector element, not from the 4th, since PSECS is now at the end.
4635 (Fcurrent_idle_time): Doc fix.
4637 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4639 Function to mark objects and remove killed buffers at once.
4640 * alloc.c (discard_killed_buffers): Rename to ...
4641 (mark_discard_killed buffers) ... new name. Add marking
4642 of remaining objects. Fix comment. Adjust users.
4643 (mark_object): Do not touch frame buffer lists here.
4644 * frame.c (delete_frame): Reset frame buffer lists here.
4646 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4648 Better workaround for GNOME bug when --enable-gcc-warnings.
4649 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4650 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4651 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4653 Simplify SIGIO usage (Bug#12408).
4654 The code that dealt with SIGIO was crufty and confusing, e.g., it
4655 played tricks like "#undef SIGIO" but these tricks were not used
4656 consistently. Simplify mostly by not #undeffing standard symbols,
4657 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4658 or not as we please) rather than "defined SIGIO" (standard symbol
4659 that we probably shouldn't #undef).
4660 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4661 Modules that need it can include it.
4662 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4663 * dispextern.h (ignore_sigio): New decl.
4664 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4665 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4666 * emacs.c (shut_down_emacs):
4667 * keyboard.c (kbd_buffer_store_event_hold):
4668 Use ignore_sigio rather than invoking 'signal' directly.
4669 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4671 (FIONREAD, SIGIO): Do not #undef.
4672 (tty_read_avail_input): Use #error rather than a syntax error.
4673 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4674 for I_PIPE, used by SETUP_SLAVE_PTY.
4675 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4676 * sysdep.c (croak): Remove; no longer needed. This bit of
4677 temporary code, with Fred N. Fish's comment that it's temporary,
4678 has been in Emacs since at least 1992!
4679 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4680 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4681 * syssignal.h (croak): Remove decl.
4682 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4683 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4684 now that we're termios-only.
4685 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4686 * term.c (dissociate_if_controlling_tty): Use #error rather than
4689 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4690 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4691 to work around GNOME bug 683906.
4692 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4693 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4694 This works around GCC bug 54561.
4696 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4698 More fixes for 'volatile' and setjmp/longjmp.
4699 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4700 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4701 (png_load_body) [HAVE_PNG]:
4702 (jpeg_load_body) [HAVE_JPEG]:
4703 New function, with most of the old parent function's body.
4704 (png_load) [HAVE_PNG]:
4705 (jpeg_load) [HAVE_JPEG]:
4706 Invoke the new function, to avoid longjmp munging our locals.
4707 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4708 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4709 longjmp is passed 2, as the C standard doesn't guarantee this.
4710 Instead, store the failure code into mgr->failure_code.
4712 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4714 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4715 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4716 (syms_of_keyboard): Remove support for unread-command-char.
4718 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4720 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4721 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4722 violation. (Bug#12426)
4724 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4726 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4728 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4730 * eval.c: Add `inhibit-debugger'.
4731 (Qinhibit_debugger): New symbol.
4732 (call_debugger): Bind it instead of Qdebug_on_error.
4733 (maybe_call_debugger): Test Vinhibit_debugger.
4734 (syms_of_eval): Define inhibit-debugger.
4735 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4736 (syms_of_xdisp): Remove inhibit-debug-on-message.
4738 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4740 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4741 If a nonvolatile local variable is written before a _longjmp to
4742 the frame containing the variable, and is read after the _longjmp,
4743 the value read is indeterminate. Some local variables of type
4744 'struct handler' and 'struct catchtag' are used in this way, so
4745 mark each of their slots as volatile if the slot can be set before
4746 _longjmp and read afterwards.
4747 * lisp.h (struct handler): var and chosen_clause are now volatile.
4748 (struct catchtag): val, next, and pdlcount are now volatile.
4750 * bidi.c (bidi_push_it, bidi_pop_it):
4751 * fns.c (copy_hash_table):
4752 * image.c (define_image_type):
4753 * keyboard.c (kbd_buffer_store_event_hold):
4754 * process.c (Fprocess_send_eof):
4755 * xfaces.c (x_create_gc) [HAVE_NS]:
4756 * xgselect.c (xg_select):
4757 Prefer assignment to memcpy when either will do.
4759 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4760 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4761 time an item is removed. No need to mark this function 'inline';
4762 the compiler knows better than we do.
4764 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4766 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4767 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4768 to change_frame_size (Bug#12388).
4769 (windowDidResize:): Pass YES to updateFrameSize.
4771 * nsterm.h: Add delay parameter to updateFrameSize.
4773 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4775 Discard killed buffers from deleted window and frame objects.
4776 This reduces an amount of references to killed buffers and
4777 helps GC to reclaim them faster.
4778 * alloc.c (discard_killed_buffers): New function.
4779 (mark_object): Use it for deleted windows and frames.
4780 (mark_object): If symbol's value is set up for a killed buffer
4781 or deleted frame, restore its global binding.
4782 * data.c (swap_in_global_binding): Add GC notice.
4783 (swap_in_symval_forwarding): Use convenient set_blv_where.
4784 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4785 * window.h: ... to here.
4787 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4789 Convenient macro to check whether the buffer is live.
4790 * buffer.h (BUFFER_LIVE_P): New macro.
4791 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4792 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4794 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4796 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4797 composition cases (Bug#12364).
4799 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4800 overhang of succeeding glyphs overlapping box cursor.
4802 * w32term.c (x_draw_glyph_string): Likewise.
4804 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4806 Simplify, document, and port floating-point (Bug#12381).
4807 The porting part of this patch fixes bugs on non-IEEE platforms
4808 with frexp, ldexp, logb.
4809 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4811 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4812 support, by removing commented-out code and briefly listing the
4813 C89 functions excluded. The commented-out stuff was confusing
4814 maintenance, e.g., we thought we needed cbrt but it was commented out.
4815 (logb): Remove decl; no longer needed.
4816 (isfinite): New macro, if not already supplied.
4817 (isnan): Don't replace any existing macro.
4818 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4819 are present on all C89 platforms.
4820 (Ffrexp): Do not special-case zero, as frexp does the right thing
4822 (Flogb): Do not use logb, as it doesn't have the desired meaning
4823 on hosts that use non-base-2 floating point. Instead, stick with
4824 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4825 frexp, to avoid getting an unspecified result.
4827 * xdisp.c (Qinhibit_debug_on_message): Now static.
4829 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4831 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4832 NSBezierPath (Bug#12131).
4834 2012-09-10 Chong Yidong <cyd@gnu.org>
4836 * fns.c (Fdelq, Fdelete): Doc fix.
4838 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4840 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4841 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4843 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4845 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4846 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4849 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4851 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4852 left fringe if the window has a left margin. This avoids leaving
4853 traces of the cursor because its leftmost pixel is not drawn over.
4855 * dispnew.c (update_window_line): When the left margin area of a
4856 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4857 that screen line. (Bug#12277)
4859 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4861 Assume C89 or later for math functions (Bug#12381).
4862 This simplifies the code, and makes it a bit smaller and faster,
4863 and (most important) makes it easier to clean up signal handling
4864 since we can stop worring about floating-point exceptions in
4865 library code. That was a problem before C89, but the problem
4866 went away many years ago on all practical Emacs targets.
4867 * data.c, image.c, lread.c, print.c:
4868 Don't include <math.h>; no longer needed.
4869 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4870 might be autoconfigured, as that never happens.
4872 * doprnt.c (DBL_MAX_10_EXP):
4873 * print.c (DBL_DIG):
4874 Remove. C89 or later always defines these.
4875 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4876 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4877 (arith_error, domain_error, domain_error2):
4878 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4879 no longer needed -- we simply return what C returns. All uses removed.
4880 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4882 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4883 Remove. All uses expanded, as these macros are no longer used
4884 more than once and are now more trouble than they're worth.
4885 (Ftan): Use tan, not sin / cos.
4886 (Flogb): Assume C89 frexp.
4887 (fmod_float): Assume C89 fmod.
4888 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4889 (init_floatfns): Remove. All uses removed.
4891 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4893 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4894 compositeToPoint for OSX < 10.6 (Bug#12390).
4896 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4898 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4899 This produces more-accurate results.
4901 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4903 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4904 changes (Bug#12088).
4906 2012-09-08 Chong Yidong <cyd@gnu.org>
4908 * syntax.c (Fstring_to_syntax): Doc fix.
4910 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4912 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4913 in the internal border.
4914 (x_set_window_size): Remove static variables and their usage.
4915 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4916 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4917 Remove fringe/internal border adjustment (Bug#11052).
4918 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4919 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4920 (ns_fix_rect_ibw): Remove.
4921 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4922 (ns_dumpglyphs_box_or_relief): Ditto.
4923 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4925 (ns_dumpglyphs_image): Ditto.
4926 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4928 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4929 their usage. Add fringe_extended_p and its use as in other terms.
4930 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4931 scroll bar was removed.
4932 (updateFrameSize): New function.
4933 (windowDidResize): Move code to updateFrameSize and call it.
4935 * nsterm.h (EmacsView): Add updateFrameSize.
4937 2012-09-07 Chong Yidong <cyd@gnu.org>
4939 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4941 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4943 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4945 More signal-handler cleanup (Bug#12327).
4946 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4947 Problem introduced when merging patches. Noted by Eli Zaretskii in
4948 <http://bugs.gnu.org/12327#67>.
4949 * floatfns.c: Comment fix.
4950 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4951 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4952 and anyway the declaration is harmless even if SIGDANGER is not defined.
4953 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4954 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4955 source files not surprisingly expected syssignal.h to define, or
4956 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4957 Include <sys/ioctl.h>, for FIONREAD.
4958 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4959 This eliminates a problem whereby other files mysteriously had
4960 to include "syssignal.h" before including "systty.h" if they
4961 wanted to use "#ifdef SIGIO".
4963 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4965 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4967 * w32.c (sigemptyset): Empty the set.
4968 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4970 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4972 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4974 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4975 (mark_object): Likewise for frame objects.
4977 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4979 * syssignal.h (handle_on_main_thread): Always declare,
4980 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4981 This ports to platforms without HAVE_PTHREAD.
4983 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4985 Signal-handler cleanup (Bug#12327).
4986 Emacs's signal handlers were written in the old 4.2BSD style with
4987 sigblock and sigmask and so forth, and this led to some
4988 inefficiencies and confusion. Rewrite these to use
4989 pthread_sigmask etc. without copying signal sets around. Also,
4990 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4991 'signal', and instead use functions that do not attempt to take
4992 over the system name space. This patch causes Emacs's text
4993 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4994 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4995 Do not include <signal.h> or "syssignal.h", as these
4996 modules do not use signals.
4997 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4998 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4999 Do not include <signal.h>, as "syssignal.h" does that for us now.
5000 * atimer.c (sigmask_atimers): New function.
5001 (block_atimers, unblock_atimers): New functions,
5002 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5004 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5005 no longer needed here.
5006 * emacs.c (main): Inspect existing signal handler with sigaction,
5007 so that there's no need to block and unblock SIGHUP.
5008 * sysdep.c (struct save_signal): New member 'action', replacing
5009 old member 'handler'.
5010 (save_signal_handlers, restore_signal_handlers):
5011 Use sigaction instead of 'signal' to save and restore.
5012 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5013 New function. All users of 'signal' modified to use set_sighandler
5014 if they're writeonly, and to use sys_signal if they're read+write.
5015 (emacs_sigaction_init, forwarded_signal): New functions.
5016 (sys_signal): Remove. All uses replaced by calls to sigaction
5017 and emacs_sigaction_init, or by direct calls to 'signal'.
5018 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5019 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5020 all uses replaced by pthread_sigmask etc. calls.
5021 * syssignal.h: Include <signal.h>.
5022 (emacs_sigaction_init, forwarded_signal): New decls.
5023 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5024 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5025 (sigmask, sys_sigmask): Remove; no longer needed.
5026 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5027 (sigblock, sigunblock, sigfree):
5028 (sigsetmask) [!defined sigsetmask]:
5029 Remove. All uses replaced by pthread_sigmask.
5030 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5031 no longer need to be replaced, and its typical old uses
5032 are now done via emacs_sigaction_init and sigaction.
5033 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5034 (sys_sigdel): Remove; unused.
5035 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5037 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5039 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5040 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5042 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5044 Explicitly mark buffer_defaults and buffer_local_symbols.
5045 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5046 mark_local_symbols here.
5047 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5048 since special buffers aren't marked here any more.
5049 (allocate_buffer): Chain new buffer with all_buffers here...
5050 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5052 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5053 (syms_of_buffer): Remove staticpro of the above.
5054 (init_buffer_once): Set names for buffer_defaults and
5055 buffer_local_symbols.
5057 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5059 Use bool for booleans in font-related modules.
5060 * font.c (font_intern_prop, font_style_to_value)
5061 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5062 (generate_otf_features, font_check_otf_features, font_check_otf)
5063 (font_match_p, font_list_entities, font_at):
5064 * fontset.c (fontset_id_valid_p, reorder_font_vector
5065 (fontset_find_font, Fset_fontset_font)
5066 (face_suitable_for_char_p) [0]:
5067 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5068 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5069 (m17n_flt_initialized, ftfont_shape_by_flt):
5070 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5071 * nsfont.m (nsfont_draw):
5072 * w32font.c (w32font_draw):
5073 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5074 Use bool for booleans.
5075 * font.h: Adjust to above API changes.
5076 (struct font, struct font_driver, struct font_driver_list):
5077 Use bool for booleans.
5078 (struct font): Remove useless member encoding_type.
5080 * fontset.c, xftfont.c: Omit unnecessary static decls.
5082 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5084 * alloc.c (mark_object): Revert window marking code
5085 since it's unsafe for the Fset_window_configuration.
5087 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5089 Fix race conditions with signal handlers and errno (Bug#12327).
5090 Be more systematic about preserving errno whenever a signal
5091 handler returns, even if it's not in the main thread. Do this by
5092 renaming signal handlers to distinguish between signal delivery
5093 and signal handling. All uses changed.
5094 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5095 * data.c (deliver_arith_signal): Rename from arith_error.
5096 * dispnew.c (deliver_window_change_signal): Rename from
5097 window_change_signal.
5098 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5099 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5100 * keyboard.c (deliver_input_available_signal): Rename from
5101 input_available_signal.
5102 (deliver_user_signal): Rename from handle_user_signal.
5103 (deliver_interrupt_signal): Rename from interrupt_signal.
5104 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5105 (deliver_child_signal): Rename from sigchld_handler.
5106 * atimer.c (handle_alarm_signal):
5107 * data.c (handle_arith_signal):
5108 * dispnew.c (handle_window_change_signal):
5109 * emacs.c (handle_fatal_signal, handle_danger_signal):
5110 * keyboard.c (handle_input_available_signal):
5111 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5112 * process.c (handle_pipe_signal, handle_child_signal):
5113 New functions, with the actual signal-handling code taken from the
5114 original respective signal handlers, sans the sporadic attempts to
5115 preserve errno, since that's now done by handle_on_main_thread.
5116 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5117 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5118 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5120 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5121 Move initialization of main_thread to sysdep.c's init_signals.
5122 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5123 our usage, and simplifies the mainline code.
5124 (record_child_status_change): New static function, as a helper
5125 for handle_child_signal, and with most of the old child handler's
5127 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5128 (handle_child_signal): Use the above.
5129 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5130 Moved here from emacs.c.
5131 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5132 code moved here from emacs.c's main function.
5133 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5134 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5135 This lets callers save and restore errno properly.
5137 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5139 Remove redundant or unused things here and there.
5140 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5141 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5142 * editfns.c (Fcompare_buffer_substrings): Likewise.
5143 * frame.h (struct terminal, struct font_driver_list):
5144 Remove redundant declarations.
5145 * window.h (Qleft, Qright): Likewise.
5147 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5149 Do not mark objects from deleted buffers, windows and frames.
5150 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5151 (mark_object): Likewise for windows and frames.
5153 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5155 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5156 buffer_defaults and buffer_local_symbols as valid objects.
5157 Return special value to denote them.
5159 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5161 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5162 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5163 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5164 (file_name_absolute_p, Fsubstitute_in_file_name):
5165 (check_executable, check_writable, Ffile_accessible_directory_p)
5166 (Fset_file_selinux_context, Fdefault_file_modes)
5167 (Finsert_file_contents, choose_write_coding_system)
5168 (Fwrite_region, build_annotations, a_write, e_write)
5170 * filelock.c (boot_time_initialized, get_boot_time)
5171 (get_boot_time_1, lock_file_1, within_one_second):
5172 * floatfns.c (in_float):
5173 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5174 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5175 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5176 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5177 * window.c (compare_window_configurations):
5178 Use bool for booleans.
5179 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5180 (Fdefault_file_modes): Now mode_t, not int, for modes.
5181 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5182 (internal_delete_file): Now returns void, not a (boolean) int,
5183 since nobody was looking at the return value.
5184 * lisp.h, window.h: Adjust to above API changes.
5186 * xdisp.c (set_message): Simplify and reindent last change.
5188 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5190 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5192 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5194 * eval.c (call_debugger): Make the function non-static so that we
5195 can call it from set_message.
5197 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5198 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5200 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5202 Give more-useful info on a fatal error (Bug#12328).
5203 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5204 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5205 of doing the work ourselves.
5206 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5207 do most of the work.
5208 (fatal_error_backtrace): New function, taken from the guts
5209 of the old fatal_error_signal, but with a new option to output
5211 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5212 info about the signal than just its number.
5213 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5214 * sysdep.c: Include <execinfo.h>
5215 (emacs_backtrace): New function, taken partly from the previous
5216 code of the 'die' function.
5217 (emacs_abort): Call fatal_error_backtrace rather than abort.
5219 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5221 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5222 eager (load-time) macro-expansion.
5223 * lisp.mk (lisp): Add macroexp.
5225 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5227 Simplify redefinition of 'abort' (Bug#12316).
5228 Do not try to redefine the 'abort' function. Instead, redo
5229 the code so that it calls 'emacs_abort' rather than 'abort'.
5230 This removes the need for the NO_ABORT configure-time macro
5231 and makes it easier to change the abort code to do a backtrace.
5232 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5233 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5234 Remove; sysdep.c's emacs_abort now takes its place.
5235 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5236 'abort' changed to use 'emacs_abort'.
5237 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5238 (abort) [!defined abort]: Rename to ...
5239 (emacs_abort): ... new name.
5240 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5241 the place of the old 'abort' in emacs.c.
5242 * w32.c, w32fns.c (abort): Do not #undef.
5243 * w32.c (emacs_abort): Rename from w32_abort.
5245 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5247 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5248 offsets[j].dv, since the y axis of the screen coordinates points
5249 down, while the y axis of the font definition coordinates points
5250 up. This fixes display of Arabic diacritics such as KASRA and
5251 KASRATAN. (Bug#11860)
5253 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5255 Be more systematic about _setjmp vs setjmp.
5256 * alloc.c (test_setjmp, mark_stack):
5257 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5258 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5259 (png_load, my_error_exit, jpeg_load):
5260 * process.c (send_process_trap, send_process):
5261 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5262 The underscored versions are up to 30x faster on some hosts.
5263 Formerly, the code used setjmp+longjmp sometimes and
5264 _setjmp+_longjmp at other times, with no particular reason to
5265 prefer setjmp+longjmp.
5267 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5269 Fix minor problem found by static checking.
5270 * buffer.c (Fdelete_all_overlays): Return nil.
5272 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5274 * buffer.c (Fdelete_all_overlays): New function.
5276 2012-09-03 Chong Yidong <cyd@gnu.org>
5278 * gtkutil.c: Add extern decl for Qxft.
5280 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5282 * emacs.c, eval.c: Use bool for boolean.
5283 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5284 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5285 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5286 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
5287 (main, decode_env_path, Fdaemon_initialized):
5288 * eval.c (call_debugger, Finteractive_p, interactive_p):
5289 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
5290 (maybe_call_debugger, Fbacktrace):
5291 * process.c (read_process_output, exec_sentinel):
5292 Use bool for booleans.
5293 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5294 All callers changed.
5295 * eval.c (interactive_p): Omit always-true boolean argument
5296 EXCLUDE_SUBRS_P. All callers changed.
5297 * dispextern.h, lisp.h: Reflect above API changes.
5298 * firstfile.c (dummy): Use the address of 'main', whose signature
5299 won't change, instead of the address of 'initialize', whose
5300 signature just changed from int to bool.
5301 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5302 * msdos.c (fatal_error_in_progress): ... from here.
5303 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5305 (redisplay_internal, unwind_redisplay): Simply clear
5306 REDISPLAYING_P when unwinding, instead of saving its previous,
5307 always-false value and then restoring it.
5309 Clean up some extern decls.
5310 Mostly, this hoists extern decls out of .c files and into .h files.
5311 That way, we're more likely to catch errors if the interfaces change.
5312 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5313 declare xg_mark_data.
5314 * dispextern.h (x_frame_parm_handlers):
5316 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5317 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
5318 (Qultra_bold, Qoblique, Qitalic):
5319 Move extern decl here from .c file.
5320 * alloc.c (xg_mark_data) [USE_GTK]:
5322 * eval.c (Qlexical_binding):
5323 * fns.c (time) [!HAVE_UNISTD_H]:

5329 * process.c (QCfamily, QCfilter):
5330 * widget.c (free_frame_faces):
5331 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
5332 * xfont.c (x_clear_errors):
5333 * xterm.c (x_frame_parm_handlers):
5334 Remove now-redundant extern decls.
5335 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5336 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5338 * xfaces.c: Remove unnecessary static decls.
5339 * xterm.c (updating_frame): Remove decl of nonexistent object.
5341 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5342 when building globals.h, as the objects that are not built on
5343 this host are not needed to compile C files on this host.
5345 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5347 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
5349 * frame.h: Add missing prototype for x_wm_set_size_hint.
5351 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

5355 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
5356 (Fsubstitute_command_keys):

5361 (make_buffer_string, make_buffer_string_both)
5362 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

5375 * keyboard.c (decode_timer):
5376 Use bool for boolean.
5377 * intervals.h, lisp.h, systime.h: Reflect above API changes.

5380 2012-09-02 Chong Yidong <cyd@gnu.org>
5382 * keymap.c (push_key_description): Print M-TAB as C-M-i
5385 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5387 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
5388 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

5393 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
5395 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5397 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5398 more than one grapheme cluster passed to the shaper: compute the
5399 offset adjustment values separately for each cluster. (Bug#11860)
5401 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5402 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5403 about implicit conversions from integer to pointer.
5405 2012-09-01 Daniel Colascione <dancol@dancol.org>
5407 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5408 system used too early.
5410 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
5412 Better seed support for (random).
5413 * emacs.c (main): Call init_random.
5414 * fns.c (Frandom): Set the seed from a string argument, if given.
5415 Remove long-obsolete Gentzel cruft.

5417 (init_random): New function.
5419 2012-09-01 Daniel Colascione <dancol@dancol.org>
5421 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
5422 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
5423 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
5424 x_wm_set_size_hint, x_query_colors, x_real_positions,
5425 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
5426 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
5427 all of which have been moved to common code.
5429 * xfaces.c: Include TERM_HEADER instead of listing all possible
5430 window-system headers.
5432 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
5435 * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
5436 directly accessing frame internals.
5438 * w32font.h: Include font.h. Define syms_of_w32font and
5441 * process.c: Include TERM_HEADER instead of listing all possible
5442 window-system headers.
5444 * nsterm.h: Remove declarations now in frame.h.
5445 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
5447 * menu.c: Include TERM_HEADER instead of listing all possible
5448 window-system headers.
5450 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
5453 * keyboard.c: Include TERM_HEADER instead of listing all possible
5454 window-system headers.
5456 * image.c: Include TERM_HEADER instead of listing all possible
5457 window-system headers. Declare Vlibrary_cache when compiling for
5460 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
5461 window system declarations.
5463 * frame.h: Move common functions here: set_frame_menubar,
5464 x_set_window_size, x_sync, x_get_focus_frame,
5465 x_set_mouse_position, x_set_mouse_pixel_position,
5466 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5482 window-system headers.
5484 * ccl.h: Include character.h.
5486 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
5487 the current window system; include in list of objects to link into
5490 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5492 Remove mark_ttys function and fix tty_display_info initialization.
5493 * lisp.h (mark_ttys): Remove prototype.
5494 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5495 to mark_ttys because all possible values of 'top_frame' slot are
5496 the frames which are reachable from Vframe_list.
5497 * term.c (mark_ttys): Remove.
5498 (init_tty): Safely initialize 'top_frame' slot with Qnil.

5511 Remove unused member of struct x_output and struct w32_output.
5512 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
5513 * w32term.h (struct w32_output): Likewise.
5515 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
5517 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
5518 does not become zero (Bug#12234).
5520 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
5522 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
5523 for GCC 4.7.1 x86-64.
5525 2012-08-30 Glenn Morris <rgm@gnu.org>
5527 * lread.c (init_lread): For out-of-tree builds, only add the
5528 source directory's site-lisp dir to the load-path if it exists,
5529 consistent with in-tree builds. (Bug#12302)
5531 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
5533 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
5534 button_values to NULL. Call setStykeMask so dialogs get a close button.
5535 (windowShouldClose:): Set window_closed.
5536 (dealloc): New member, free button_values.
5537 (process_dialog:): Make member function. Remove window argument,

5546 (initFromContents:isQuestion:): Adjust call to process_dialog.
5547 Code formatting change.
5548 (timeout_handler:): Set timer_fired to YES.
5549 (runDialogAt:): Set timer_fired to NO.
5550 Handle click on close button as quit.
5552 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5553 Add window_closed and button_values. Add void as return value for
5554 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5555 Add process_dialog as new member.
5557 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5559 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
5560 is not one of the heaps we manage. (Bug#12242)
5562 2012-08-28 Glenn Morris <rgm@gnu.org>
5564 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

5576 if the buffer is dead.
5577 (Fother_buffer, other_buffer_safely): Remove redundant
5580 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
5582 Always use set_buffer_if_live to restore original buffer at unwind.

5620 (change_frame_size_1, sit_for):
5621 Use bool for boolean.
5622 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
5623 and remove last int (actually boolean) argument, which was always 0.
5624 All callers changed.
5625 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
5626 * dispextern.h (struct composition_it): Use bool for boolean.
5627 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
5628 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
5629 * dired.c (file_name_completion):
5630 Use bool for boolean. (This was missed in an earlier change.)
5632 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5634 * window.c (Fset_window_configuration): Revert first part of
5637 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
5639 * nsterm.h (NSPanel): New class variable dialog_return.
5641 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
5642 Initialize dialog_return.
5643 (windowShouldClose:): Use stop instead of stopModalWithCode.
5644 (clicked:): Ditto, and also set dialog_return (Bug#12258).
5645 (timeout_handler:): Use stop instead of abortModal. Send a dummy
5647 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

5662 Use bool for booleans.
5663 * dired.c (file_name_completion):
5664 * process.h (fd_callback):
5665 Omit int (actually boolean) argument. It wasn't being used.

5692 Use bool for booleans.
5693 * coding.h, lisp.h: Reflect above API changes.
5694 * coding.c: Remove unnecessary static function decls.
5695 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5696 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5697 not a boolean 'int', since callers never look at the return value.
5698 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5699 * coding.h (decoding_buffer_size, encoding_buffer_size)
5700 (emacs_mule_string_char): Remove unused extern decls.
5701 (struct iso_2022_spec, struct coding_system):

5707 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5709 Fix spare memory change (Bug#12286).
5710 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5711 (valid_lisp_object_p): Likewise.
5713 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5715 * window.c (Fset_window_configuration): Record any window's old
5716 buffer if it's replaced (see Bug#8789). If the new current
5717 buffer doesn't appear in the selected window, go to its old
5720 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5722 Special MEM_TYPE_SPARE to denote reserved memory.
5723 * alloc.c (enum mem_type): New memory type.
5724 (refill_memory_reserve): Use new type for spare memory.
5725 This prevents live_cons_p and live_string_p from incorrect
5726 detection of uninitialized objects from spare memory as live.
5728 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5731 * Makefile.in (.PHONY): versioclean -> versionclean.
5733 Remove unused external symbols.
5734 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
5735 * window.c (Qwindow_valid_p, decode_valid_window):
5736 Now static, not extern.
5737 * data.c (Qinterval): Remove; unused.
5738 (syms_of_data): Do not define 'interval'.
5739 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
5740 * window.h (decode_valid_window):

5754 (map_sub_char_table):
5755 Use bool for boolean.
5756 * character.c (str_to_unibyte): Omit last boolean argument; it was
5757 always 0. All callers changed.
5758 * character.h, charset.h: Adjust to match previous changes.
5759 * character.h (char_printable_p): Remove decl of nonexistent function.
5760 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5761 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5762 are all boolean, so make them single-bit bitfields.
5764 * lisp.h (ASET): Remove attempt to detect side effects.
5765 It was meant to be temporary and it often doesn't work,
5766 because when IDX has side effects the behavior of IDX==IDX
5767 is undefined. See Stefan Monnier in
5768 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5770 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5772 * lisp.h (functionp): New function (extracted from Ffunctionp).
5773 (FUNCTIONP): Use it.
5774 * eval.c (Ffunctionp): Use it.
5776 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5778 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5779 as that's faster and simpler than static storage. Don't bother
5780 with the g_main_context_query overhead if g_main_context_pending
5781 says no events are pending.
5782 (gfds, gfds_size): Remove these static vars.
5783 (xgselect_initialize): Remove; no longer needed.
5784 All uses and decls removed.
5786 * emacs.c (fatal_error_signal_hook): Remove.
5787 All uses removed. This leftover from old code was always 0.
5789 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5790 * casefiddle.c (casify_object, casify_region):
5791 * casetab.c (set_case_table):

5793 * category.h (CHAR_HAS_CATEGORY):
5794 Use bool for booleans, instead of int.
5796 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5798 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5800 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5802 On assertion failure, print backtrace if available.
5803 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5804 (die) [ENABLE_CHECKING]: Print a backtrace if available.
5805 * Makefile.in (LIB_EXECINFO): New macro.
5808 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
5809 * bytecode.c (exec_byte_code):
5810 * callint.c (check_mark, Fcall_interactively):
5811 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)

5813 * lisp.h (USE_SAFE_ALLOCA):
5814 Use bool for booleans, instead of int.
5815 * lisp.h, process.h: Adjust prototypes to match above changes.
5816 * callint.c (Fcall_interactively): Don't assume the mark's
5817 offset fits in 'int'.
5819 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>

5828 (mmap_enlarge, mmap_set_vars):
5829 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5830 Use bool for booleans, instead of int.
5831 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5832 since the 1-or-0 return value is always ignored anyway.
5833 (mmap_initialized_p):
5834 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5835 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5837 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5839 * bidi.c: Use bool for boolean.
5840 This is a bit more readable, and makes the text segment of bidi.o
5841 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5842 Presumably it's faster too.
5843 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):

5850 Use bool for booleans, instead of int.
5851 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5852 (bidi_unshelve_cache): Adjust decls to match code.

5866 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5867 compile time tests instead of run time tests on systems that do
5869 (FRAME_MAC_P): Remove leftover from deleted code.
5870 * frame.c (syms_of_frame): Remove leftover from deleted code.
5872 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5874 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5876 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5878 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5879 Otherwise, the compiler complains about (A?B:C) where B is void
5880 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5881 (fontset_add): Return void, for FONTSET_ADD.
5883 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>

5893 (mark_stack, valid_pointer_p, make_pure_string)
5894 (Fgarbage_collect, survives_gc_p, gc_sweep):
5895 Use bool for booleans, instead of int.
5896 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5897 Remove unused local.
5898 * alloc.c (PURE_POINTER_P):
5899 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.

5906 * lread.c (readchar, read1):
5907 * print.c (Fprin1_to_string):
5908 * xdisp.c (push_message):
5909 Use bool for booleans affected directly or indirectly by
5912 Make recently-introduced setters macros.

5914 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5915 (set_fontset_default, set_fontset_fallback): Rename from their
5916 upper-case counterparts, and make them functions rather than macros.
5917 This is more consistent with the other recently-introduced setters.
5918 These don't need to be inline, since they're local.

5925 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5927 * lisp.h (vcopy): Use memcpy rather than our own loop.
5928 This fixes a performance regression introduced by the recent
5929 addition of vcopy. This means 'vcopy' will need to be modified
5930 for a copying collector, but that's OK. Also, tighten the
5931 checking in the assertion.

5935 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5936 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5937 non-base glyph for the width of the base character, according to
5938 what x_draw_composite_glyph_string_foreground expects.
5939 Generate WADJUST value according to composition_gstring_width's
5940 expectations, to produce correct width of the composed character.
5941 Reverse the sign of the DU offset produced by ScriptPlace.
5943 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5945 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.

5973 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5976 2012-08-20 Glenn Morris <rgm@gnu.org>
5978 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5979 Don't assume that `ln -f' works.
5981 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5983 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5984 and later about non-assignments with no effect. See discussion at
5985 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for

6009 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6010 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6011 (set_hash_key_and_value, set_hash_index, set_hash_next)
6012 (set_hash_hash): New functions.
6013 * charset.c, fns.c: Adjust users.

6025 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6027 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6029 Rely on <config.h> + <unistd.h> to declare 'environ',
6030 as gnulib does this if the system doesn't.
6031 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6032 Remove declaration. MS-Windows declares it on stdlib.h which is
6033 included by conf_post.h.
6034 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6035 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6036 * vm-limit.c: Include <unistd.h>, for 'environ'.
6038 * unexaix.c, unexcoff.c: Include "mem-limits.h".

6041 * xdisp.c (handle_invisible_prop): Make it a bit faster
6042 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6044 2012-08-19 Chong Yidong <cyd@gnu.org>

6055 (Fkill_local_variable): Likewise.
6057 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6059 * nsfont.m (ns_ascii_average_width): Ensure the string
6060 ascii_printable is initialized with a null-terminated character

6066 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6067 Return void, not Lisp_Object. Otherwise, the compiler
6068 complains about (A?B:C) where B is void and C is Lisp_Object
6069 when compiling CHAR_TABLE_SET, due to the recent change to
6070 the API of sub_char_table_set_contents.
6072 2012-08-18 Chong Yidong <cyd@gnu.org>
6074 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE

6902 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6903 * w32.c (init_environment): Change the default values of many
6904 environment variables in dflt_envvars[] to NULL, to avoid pushing
6905 them into environment when they were not already defined.
6906 Remove the code that deletes site-lisp subdirectories from the default
6907 value of EMACSLOADPATH, as it is no longer needed.
6908 (check_windows_init_file): Now external, not static.
6909 Use Vload_path as is, without adding anything, as this function is now
6910 called when Vload_path is already set up.
6912 * w32.h (check_windows_init_file): Add prototype.
6914 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
6915 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
6916 compatibility with Posix platforms.
6917 (main): Move the call to check_windows_init_file to here from

6920 any, in the DEFALT argument into the root of the Emacs build or
6921 installation tree, as appropriate.
6923 * callproc.c (init_callproc_1): Call decode_env_path instead of
6924 doing its equivalent by hand.
6925 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
6926 the code that sets Vexec_path run on MS-Windows.

6942 Remove unnecessary casts involving pointers.
6943 These casts are no longer needed now that we assume C89 or later,

6957 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6958 Remove unnecessary pointer casts.
6959 * alloc.c (record_xmalloc): New function.
6960 * lisp.h (record_xmalloc): New decl.
6961 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6962 more like a function. This is because the pointer cast is not
6963 needed. All uses changed.
6964 * print.c (print_string, print_error_message): Avoid length recalc.
6966 Improve fix for macroexp crash with debugging (Bug#12118).
6967 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6968 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6969 not supposed to be invoked from the garbage collector.

6971 (gc_aset): New function, which is like ASET but can be
6972 used in the garbage collector.

7001 with addition of handling of symlinks and support for 'lstat'.
7002 If possible, get file's attributes and security information by
7003 handle, not by name. Produce S_IFLNK bit for symlinks, when
7004 called from 'lstat'.
7005 (stat, lstat): New functions, call 'stat_worker'.
7006 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7007 symlinks when the underlying filesystem supports them.
7009 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7011 Fix macroexp crash on Windows with debugging (Bug#12118).
7012 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7013 checking subscripts; problem introduced with the recent
7014 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7015 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7016 since it's used in non-static inline functions now.
7018 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7019 Don't assume buffer size fits in 'int'. Remove unused local.

7039 * composite.c (COMPOSITE_INLINE):
7040 * dispnew.c (DISPEXTERN_INLINE):
7041 * sysdep.c (SYSTIME_INLINE):
7042 Define to EXTERN_INLINE, so that the corresponding functions
7043 are compiled into code.
7044 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7045 (INLINE_HEADER_END): New macros.
7046 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7068 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7070 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7071 This how ASET and AREF are supposed to work, and makes
7072 it easier to think about future improvements. See
7073 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7074 * charset.h (set_charset_attr): New function.

7328 does that unconditionally. Remove file, which is now empty.
7330 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
7333 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

7454 w32_console_unicode_input.
7455 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
7456 (w32_kbd_patch_key, key_event): Use the codepage returned by
7457 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

7489 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7490 enumeration constants, as PURE and HEAP are too general, and clash
7491 with other headers and sources, such as gmalloc.c and the
7492 MS-Windows system headers. All users changed.
7494 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7496 Revert last save_excursion_save and save_excursion_restore changes.
7497 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7510 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7511 arms of an 'if', not using conditional expressions; otherwise GDB
7512 complains about the types in the unevaluated arm when the argument
7513 is an integer literal.
7514 (xgetint): Simplify expression.
7515 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7516 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7517 Zaretskii in <http://bugs.gnu.org/12036#13>.
7518 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7519 needed now that we have gdb_make_enums_visible.
7520 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7521 (enum enum_USE_LSB_TAG):
7522 New enum types, packaging up enums that need to be exported to GDB.

7541 * xfns.c (syms_of_xfns): Likewise.
7543 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

7546 * lisp.h (struct Lisp_Excursion): New data type.
7547 (PVEC_EXCURSION): New pseudovector type.
7548 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
7549 to deal with it. Adjust comments.

7564 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7565 emacs.c, as this is a more-suitable home. Had this been done earlier
7566 the fix for 12036 would have avoided some of the problems noted in
7567 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7568 would have been more obvious.
7569 * emacs.c: Do not include <verify.h>; no longer needed.
7570 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7571 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7572 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

7578 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7579 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7580 not be usable in #if. This simplifies things.
7582 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7584 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
7586 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

7589 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7590 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7591 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7592 Adjust to changes in lisp.h and emacs.c, by using
7593 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7594 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7595 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7596 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7597 instead of gdb_valbits.
7598 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7599 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7600 instead of gdb_array_mark_flag.
7601 (xboolvector): Get size from $->size, not $->header.size.
7602 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7603 (xreload, hook-run, hookpost-run): Remove.
7604 * emacs.c: Include <verify.h>.
7605 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7606 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7608 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7609 (gdb_USE_LSB_TAG): New enum constants.
7610 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7611 Also define these as enum constants, so they're visible to GDB.
7612 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7613 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7614 as constants, so they're visible to GDB.
7615 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
7616 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
7617 Now enum constants, not macros, so they're visible to GDB.
7618 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7619 more convenient now. All uses changed.
7620 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7621 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7623 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

7628 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
7630 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7631 add argument, tune behavior, and adjust all callers.
7633 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7635 Use typedef for EMACS_INT, EMACS_UINT.
7636 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7637 than macros. This simplifies debugging in the usual case, since
7638 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7639 and it allows expressions involving EMACS_INT casts.
7640 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7642 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

7650 that FOCUS-FRAME can be omitted.
7652 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7654 Adjust buffer text indirection counters at the end of Fkill_buffer.
7655 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7656 buffer is definitely dead. This should really fix an issue reported
7657 by Christoph Scholtes again. (Bug#12007).
7658 (init_buffer_once): Initialize indirection counters of
7659 buffer_defaults and buffer_local_symbols (for sanity and safety).
7661 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7663 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7664 and continuation glyphs on tooltip frames, leave them at zero.
7665 Avoids continued lines in tooltips. (Bug#11832)
7667 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
7669 Simplify copy_overlay.
7670 * buffer.c (copy_overlay): Simplify. Use build_marker.

8504 * nsterm.m (ns_term_init):
8505 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8506 * nsterm.m (ns_term_init):
8507 Avoid the need for strncpy, by using build_string or
8508 make_unibyte_string directly. Use dtoastr, not snprintf.
8509 * process.c (Fmake_network_process): Diagnose service names that
8510 are too long, rather than silently truncating them or creating

8578 * s/gnu.h (DATA_START): Move definitions to configure.
8580 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8581 We include usg5-4-common.h, which defines them both.
8583 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8584 O_RDONLY already includes it).
8586 Stop ns builds setting the EMACSLOADPATH environment variable.
8587 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8588 Now it does not set EMACSLOADPATH, just returns the load-path string.
8589 * nsterm.h: Update accordingly.
8590 * lread.c [HAVE_NS]: Include nsterm.h.
8591 (init_lread) [HAVE_NS]: Use ns_load_path.
8592 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
8594 2012-07-09 Glenn Morris <rgm@gnu.org>
8596 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8597 since the included bsd-common.h does so.
8599 Stop ns builds setting the EMACSPATH environment variable.
8600 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8601 (ns_init_paths): Do not set EMACSPATH.
8602 * nsterm.h (ns_exec_path): Add it.
8603 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8606 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8608 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8610 * process.c (wait_reading_process_output): 'waitchannels' was unset
8611 when read_kbd || !NILP (wait_for_cell); fix this.
8613 Add GCC-style 'const' attribute to functions that can use it.
8614 * character.h (char_resolve_modifier_mask):
8615 * keyboard.h (make_ctrl_char):
8616 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
8617 (init_character_once, next_almost_prime, init_fns, init_image)
8618 (flush_pending_output, init_sound):
8619 * mem-limits.h (start_of_data):
8620 * menu.h (finish_menu_items):
8621 Add ATTRIBUTE_CONST.
8622 * emacs.c (DEFINE_DUMMY_FUNCTION):
8623 Declare the dummy function with ATTRIBUTE_CONST.
8624 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8625 Add decls with ATTRIBUTE_CONST.
8627 Minor improvements to make_formatted_string.
8628 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8629 where int is good enough, as vsprintf returns an int.
8630 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8632 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8634 Use make_formatted_string to avoid double length calculation.
8635 * lisp.h (make_formatted_string): New prototype.
8636 * alloc.c (make_formatted_string): New function.
8637 * buffer.c (Fgenerate_new_buffer_name): Use it.
8638 * dbusbind.c (syms_of_dbusbind): Likewise.
8639 * editfns.c (Fcurrent_time_zone): Likewise.
8640 * filelock.c (get_boot_time): Likewise.
8641 * frame.c (make_terminal_frame, set_term_frame_name)
8642 (x_report_frame_params): Likewise.
8643 * image.c (gs_load): Likewise.
8644 * minibuf.c (get_minibuffer): Likewise.

8654 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
8655 * nsterm.h (ns_etc_directory): Add it.
8656 * callproc.c [HAVE_NS]: Include nsterm.h.
8657 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
8659 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8661 Move marker debugging code under MARKER_DEBUG.
8662 * marker.c (MARKER_DEBUG): Move marker debugging code under
8663 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8664 for bootstrap with --enable-checking (~3x slowdown reported
8665 by Juanma Barranquero <lekktu@gmail.com>).
8666 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8668 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8670 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8671 See <http://bugs.gnu.org/11825#29>.
8673 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8675 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8676 has no font, use the frame's font. (Bug#11813)
8677 (display_line): Add commentary about displaying truncation glyphs
8679 (produce_special_glyphs): Move here from term.c.
8681 * term.c (produce_special_glyphs): Move to xdisp.c.
8683 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8686 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8688 * xdisp.c (display_line): Avoid warning about implicit declaration
8691 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8693 * lisp.h: Remove empty conditional.
8695 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8697 * lread.c (load_path_check): Now static.
8699 Fix some minor --with-ns problems found by static checking.
8700 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8701 (x_set_font) [!HAVE_X_WINDOWS]:
8702 * image.c (xpm_load_image) [HAVE_NS]:
8703 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8704 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8705 Remove unused local.
8706 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8707 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8708 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8709 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8710 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8711 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8712 Fix pointer signedness problem.
8713 * xfaces.c (FRAME_X_FONT_TABLE):
8714 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8716 2012-07-07 Glenn Morris <rgm@gnu.org>
8718 * lread.c (load_path_check): New function, split from init_lread.
8719 (init_lread): Reorganize. Motivation:
8720 If EMACSLOADPATH is set, check/warn about that rather than the
8721 defaults, which we are not going to use. Hence we can remove
8722 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8723 Don't warn if site-lisp directories are missing.
8724 If not installed, start from a blank load-path, since
8725 PATH_LOADSEARCH refers to the eventual installation directories.
8727 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8729 Support truncation and continuation glyphs on GUI frames, when
8730 fringes are disabled. (Bug#11832)
8731 * xdisp.c (init_iterator): Get dimensions of truncation and
8732 continuation glyphs even if on GUI frames.
8733 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8734 or both, are absent.
8735 (start_display, move_it_in_display_line_to): Handle the case of a
8736 GUI frame without a fringe to display continuation or truncation
8738 (insert_left_trunc_glyphs): Support GUI frames: make sure
8739 truncation glyphs overwrite enough glyphs from the current line to
8740 have sufficient space in pixels.
8741 (display_line): Support truncation and continuation glyphs on GUI
8742 frames. If some spare pixels are left on the line after inserting
8743 the truncation glyphs, fill that space with a stretch glyph of a
8744 suitably computed width.
8746 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8747 produce_glyphs, to support GUI sessions.
8749 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8751 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8753 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8755 Do not require float-time's arg to fit in time_t (Bug#11825).
8756 This works better on hosts where time_t is unsigned, and where
8757 float-time is applied to the (negative) difference between two times.
8758 * editfns.c (decode_time_components): Last arg is now double *,
8759 not int *, and means to store all the result as a double, without
8760 worrying about whether the seconds part fits in time_t.
8761 All callers changed.
8762 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8763 All callers changed.
8764 (Ffloat_time): Do not fail merely because the specified time falls
8765 outside of time_t range.
8767 2012-07-07 Glenn Morris <rgm@gnu.org>
8769 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
8770 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

8773 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
8775 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8776 Update dependencies.
8778 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8780 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8782 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

8784 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8785 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8786 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
8787 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
8789 * xfont.c (compare_font_names): Redo to omit the need for casts.
8791 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8793 * xfns.c (Fx_change_window_property): Doc fix.
8794 * w32fns.c (Fx_change_window_property): Doc fix.
8796 * w32fns.c (Fx_window_property): Accept the same arguments as the
8797 X Windows version. Doc fix.
8798 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8800 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8801 Eli Zaretskii <eliz@gnu.org>
8803 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8804 Windows-specific code from nt/config.nt moved here.
8805 Obsolete settings removed.
8807 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8809 * process.c: Avoid unnecessary calls to gettime.
8810 (wait_reading_process_output): Don't get the time of day
8811 when gobbling data immediately and not waiting, as there's no need
8812 for it in that case. This removes a FIXME.
8814 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8816 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8817 is defined (Bug#11768).
8819 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8821 Fix marker debugging code.
8822 * marker.c (byte_char_debug_check): Do not perform the check
8823 if buffer is not multibyte.
8824 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8825 Call byte_char_debug_check with correct arguments.
8827 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8829 Compile marker debugging code only if ENABLE_CHECKING is defined.
8830 * marker.c (byte_char_debug_check, count_markers):
8831 Use only if ENABLE_CHECKING is defined.
8832 (byte_debug_flag): Remove.
8833 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8834 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8836 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8838 Avoid code repetition in marker-related functions.
8839 * marker.c (attach_marker): New function.
8840 (Fset_marker, set_marker_restricted, set_marker_both)
8841 (set_marker_restricted_both): Use it.
8842 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8843 Consistently rename charno to charpos.
8844 (marker_position): Add eassert.
8845 (marker_byte_position): Convert to eassert.

8857 * lisp.h (build_marker): New prototype.
8858 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
8859 * composite.c (autocmp_chars): Likewise.
8860 * editfns.c (buildmark): Remove.
8861 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
8862 (save_restriction_save): Use build_marker.
8863 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
8864 * window.c (save_window_save): Likewise.
8866 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8868 Do not use Fdelete_overlay in delete_all_overlays
8869 to avoid redundant calls to unchain_overlay.
8870 * buffer.c (drop_overlay): New function.
8871 (delete_all_overlays, Fdelete_overlay): Use it.
8872 * minibuf.c (get_minibuffer): Fix comment.
8874 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8876 Port to OpenBSD 5.1 amd64.
8877 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8878 This is needed for OpenBSD, and should be harmless on all BSD systems.
8879 Also, include <sys/sysctl.h>, as it should be available on all
8880 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8881 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8882 use p_pid member, not kp_proc.pid.
8884 2012-07-06 Glenn Morris <rgm@gnu.org>
8886 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8888 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8890 More xmalloc and related cleanup.
8891 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
8892 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

8898 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
8899 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8901 Omit needless casts involving void * pointers and allocation.
8902 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8903 as the former is more robust if P's type is changed.
8904 Prefer xzalloc to xmalloc + memset 0.
8905 Simplify malloc-or-realloc to realloc.
8906 Don't worry about xmalloc returning a null pointer.
8907 Prefer xstrdup to xmalloc + strcpy.
8908 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8910 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8911 alloca of a constant.
8913 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8915 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8916 hscroll is larger than the line width. Fixes long and futile
8917 looping inside extend_face_to_end_of_line (on a TTY) producing
8918 glyphs that are not needed and thrown away.
8920 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8922 * marker.c (set_marker_restricted_both): Simplify by using
8925 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

8936 followed by gtk_box_set_homogeneous (Bug#11768).
8937 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8938 (update_theme_scrollbar_width, xg_create_scroll_bar):
8939 Use gtk_scrollbar_new (Bug#11768).
8940 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
8941 (is_box_type): New function (Bug#11768).
8942 (xg_tool_item_stale_p): Call is_box_type.
8943 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
8944 with default display (Bug#11768).
8946 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8948 * xdisp.c (window_hscroll_limited): New function.
8949 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8950 coordinates when window's hscroll is set to insanely large
8953 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8955 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
8956 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
8958 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

9017 Problem reported by Troels Nielsen in
9018 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9020 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9022 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9023 This should be fixed in a better way; see Eli Zaretskii in
9024 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9025 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9027 * fileio.c (time_error_value): Rename from special_mtime.
9028 The old name's problems were noted by Eli Zaretskii in
9029 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9031 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9032 This variable's comment says Emacs needs at least one GDB-visible
9033 symbol of type enum pvec_type, to work around GDB problems.
9034 The symbol's value doesn't matter.
9036 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9037 that causes compilation to fail on pre-C99 compilers.
9039 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9041 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9042 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9044 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

9047 headers for buffer_defaults and buffer_local_symbols.
9048 Reported by Juanma Barranquero <lekktu@gmail.com>.
9050 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9052 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9053 * lisp.h (enum pvec_type): Use fewer bits.
9054 (PSEUDOVECTOR_SIZE_BITS): New constant.
9055 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9056 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9057 change in pvec_type.
9058 (PSEUDOVECTOR_TYPEP): New macro.
9059 (TYPED_PSEUDOVECTORP): Use it.
9060 * fns.c (internal_equal): Adapt code to extract pvectype.

9062 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9063 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9064 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9065 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9066 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9067 abusing vector->header.next.nbytes.
9068 (live_vector_p): Use PVEC_TYPE.
9069 (mark_object): Adapt code to extract pvectype. Use switch.
9071 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9073 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9074 Tighten new eassert a bit.
9076 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9078 Fix compilation with --enable-gcc-warnings and -O1
9080 * doprnt.c (doprnt): Change type of tem to int, initialize
9081 to avoid compiler warning. Add eassert.
9082 * search.c (simple_search): Initialize match_byte to avoid
9083 compiler warning. Add eassert.
9085 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9087 Avoid weird behavior with large horizontal scrolls.
9088 Without this change, for example, large hscroll values would
9089 mess up Emacs's display on Fedora 15 x86, presumably due to
9090 overflows in int calculations in the display code.
9091 Also, if buffers had long lines, Emacs would freeze.
9092 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9093 (set_window_hscroll): New function, containing the old guts of
9094 Fset_window_hscroll. Return the clipped value.
9095 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9096 This avoids the need to check against PTRDIFF_MAX.
9098 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9100 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9102 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9104 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9106 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9107 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9108 since GCC 4.4.6 issues a bogus warning for them.
9110 Fix bugs in file timestamp newness comparisons.
9111 * fileio.c (Ffile_newer_than_file_p):
9112 * lread.c (Fload): Use full timestamp resolution of files,
9113 not just the 1-second resolution, so that files that are only
9114 slightly newer still count as newer.
9115 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9116 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9118 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9120 * fileio.c: Improve handling of file time marker. (Bug#11852)
9121 (special_mtime): New function.
9122 (Finsert_file_contents, Fverify_visited_file_modtime):
9123 Use it to set special mtime values consistently.
9125 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9127 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9128 marker for non-existing file. (Bug#11852)
9130 2012-07-03 Glenn Morris <rgm@gnu.org>
9132 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9133 and did not make it into globals.h).
9135 2012-07-03 Tom Tromey <tromey@redhat.com>
9137 * window.c (Fset_window_margins, Fset_window_fringes)
9138 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
9139 * textprop.c (Fprevious_property_change): No longer static.
9140 * syntax.c (Fsyntax_table_p): No longer static.

9155 * dired.c (Ffile_attributes): No longer static.
9156 * composite.c (Fcomposition_get_gstring): No longer static.
9157 * callproc.c (Fgetenv_internal): No longer static.
9159 * ccl.h: Remove EXFUNs.
9160 * buffer.h: Remove EXFUNs.
9161 * dispextern.h: Remove EXFUNs.
9162 * intervals.h: Remove EXFUNs.
9163 * fontset.h: Remove EXFUN.
9164 * font.h: Remove EXFUNs.
9165 * dosfns.c (system_process_attributes): Remove EXFUN.
9166 * keymap.h: Remove EXFUNs.
9167 * lisp.h: Remove EXFUNs.
9168 * w32term.h: Remove EXFUNs.
9169 * window.h: Remove EXFUNs.
9170 * xsettings.h: Remove EXFUN.
9171 * xterm.h: Remove EXFUN.
9173 2012-07-03 Glenn Morris <rgm@gnu.org>
9175 * lisp.h (Frandom): Make it visible to C.
9176 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9177 buffer for invisible buffers. (Bug#1229)
9179 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9181 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9182 values which aren't power of 2.
9183 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9184 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9187 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9189 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9191 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9193 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9195 * alloc.c (allocate_vector_block): Remove redundant
9196 calls to mallopt if DOUG_LEA_MALLOC is defined.
9197 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9198 avoid calls to mallopt if zero_vector is returned.
9200 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9202 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9203 is enabled, avoid dereferencing NULL current_sblock if
9206 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9208 Cleanup basic buffer management.
9209 * buffer.h (struct buffer): Change layout to use generic vector
9210 marking code. Fix some comments. Change type of 'clip_changed'
9211 to bitfield. Remove unused #ifndef old.
9212 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9213 (GET_OVERLAYS_AT): Fix indentation.
9214 (for_each_per_buffer_object_at): New macro.
9215 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
9216 (Fbuffer_local_variables): Use it.
9217 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
9218 * alloc.c (allocate_buffer): Adjust to match new layout of
9219 struct buffer. Fix comment.
9220 (mark_overlay): New function.
9221 (mark_buffer): Use it. Use mark_vectorlike to mark normal
9222 Lisp area of struct buffer.
9223 (mark_object): Use it. Adjust marking of misc objects
9224 and related comments.
9226 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9228 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9229 wrapper that is not needed because the wrapped code is a no-op (zero
9230 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9231 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9233 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9235 * alloc.c (mark_buffer): Simplify. Remove prototype.
9236 (mark_object): Add comment. Reorganize marking of vector-like
9237 objects. Use CHECK_LIVE for all vector-like objects except buffers
9238 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9239 Avoid redundant calls to mark_vectorlike for bool vectors.
9241 2012-06-30 Glenn Morris <rgm@gnu.org>
9243 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9245 * epaths.in (PATH_SITELOADSEARCH): New.
9246 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9247 This is rather than relying on --enable-locallisppath elements
9248 having "site-lisp" in their names. (Bug#10208#25, 11658)
9250 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9252 * w32proc.c (sys_select): Accept and ignore one more argument.
9254 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9256 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9257 (pselect) [!MS_DOS]: Redirect to sys_select.
9259 * sysdep.c: Don't include dos.h and dosfns.h.
9261 * process.c (sys_select):
9262 * msdos.c (sys_select): Accept one more argument and ignore it.
9264 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9265 adapt data types and code to that.
9268 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9269 which clashes with the gnulib function of the same name.
9271 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9273 * font.c (font_style_to_value, font_style_symbolic)
9274 (font_prop_validate_style): Add type checks for values in
9277 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9279 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9282 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9284 * xdisp.c (try_window_id): Undo last change.
9286 * w32.c (getwd): Adjust commentary about startup_dir.
9287 (init_environment): Always call sys_access, even in non-MSVC
9288 builds. Don't chdir to the directory of the Emacs executable.
9289 This undoes code from 1997 which was justified by the need to
9290 "avoid conflicts when removing and renaming directories". But its
9291 downside was that every relative file name was being interpreted
9292 relative to the directory of the Emacs executable, which can never
9293 be TRT. In particular, it broke sys_access when called with
9294 relative file names.
9295 (sys_access): Map GetLastError to errno.
9297 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9299 * window.h (struct window): Change type of 'fringes_outside_margins'

9303 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9306 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9308 * gnutls.c (emacs_gnutls_handshake):
9309 Add QUIT to make the loop interruptible.
9311 2012-06-29 Glenn Morris <rgm@gnu.org>
9313 * charset.c (init_charset): Make lack of etc/charsets fatal.
9315 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9317 * editfns.c (region_limit): Fix type mismatch.
9319 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9321 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9322 undefined. Convert from xassert to eassert.
9323 * nsmenu.m: Convert from xassert to eassert.
9324 * nsterm.m: Likewise.
9326 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9328 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9330 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9332 Avoid integer overflow on scroll-left and scroll-right.
9333 * window.c (HSCROLL_MAX): New macro.
9334 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9335 overflow when requested scroll falls outside ptrdiff_t range.
9337 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9339 * window.h (struct window): Change type of 'hscroll',
9340 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9341 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9342 Adjust users accordingly.
9343 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9344 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9345 from EMACS_INT to ptrdiff_t.
9346 (make_window): Omit redundant initialization.
9348 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

9352 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9354 * window.h (struct window): Change type of 'use_time' and
9355 'sequence_number' from Lisp_Object to int.

9365 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9366 adjust comments accordingly.

9421 * alloc.c (allocate_string): Omit intervals initialization.
9422 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9423 as in make_pure_string and make_pure_c_string.

9479 * alloc.c: Remove build_string.
9480 * lisp.h: Define build_string as static inline. This provides
9481 a better opportunity to optimize away calls to strlen when the
9482 function is called with compile-time constant argument.
9483 * image.c (imagemagick_error): Convert to build_string.
9484 * w32proc.c (sys_spawnve): Likewise.
9485 * xterm.c (x_term_init): Likewise.
9487 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9489 Use sprintf return value instead of invoking strlen on result.
9490 In the old days this wasn't portable, since some sprintf
9491 implementations returned char *. But they died out years ago and
9492 Emacs already assumes sprintf returns int.
9493 Similarly for float_to_string.
9494 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9495 * ccl.c (ccl_driver):
9496 * character.c (string_escape_byte8):

9499 * print.c (print_object):
9500 * xdisp.c (message_dolog):
9501 * xfns.c (syms_of_xfns):
9502 Use sprintf or float_to_string result to avoid need to call strlen.
9503 * data.c (Fnumber_to_string):
9504 Use make_unibyte_string, since the string must be ASCII.
9505 * lisp.h, print.c (float_to_string): Now returns int length.
9506 * term.c (produce_glyphless_glyph):
9507 Use sprintf result rather than recomputing it.
9509 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9510 * Makefile.in (ALL_CFLAGS):
9511 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

9608 * keyboard.c (kbd_buffer_get_event):
9609 * process.c (Faccept_process_output):
9610 Use it to avoid bogus compiler warnings with obsolescent GCC versions.

9612 when time_t is unsigned and as wide as intmax_t.
9613 See <http://bugs.gnu.org/9000#51>.
9615 2012-06-23 Eli Zaretskii <eliz@gnu.org>

9678 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9680 Support higher-resolution time stamps (Bug#9000).
9681 The time stamps are only nanosecond-resolution at the C level,
9682 since that's the best that any real-world system supports now.
9683 But they are picosecond-resolution at the Lisp level, as that's
9684 easy, and leaves room for future OS improvements.
9686 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9689 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9690 Don't get current time unless it's needed.
9692 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9693 now provides it if it's absent.
9694 (start_atimer): Port to higher-res time stamps.
9695 Check for time stamp overflow. Don't get current time more
9696 often than is needed.
9698 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9699 Include systime.h, not time.h.
9700 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9702 * dired.c: Include stat-time.h.
9703 (Ffile-attributes): File times now have higher resolution.

9706 (struct image): Timestamp now has higher resolution.
9708 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9709 has at least microseconds now. All uses removed.
9710 (update_frame, update_single_window, update_window, update_frame_1)
9711 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9712 (duration_to_sec_usec): Remove; no longer needed.
9714 * editfns.c (time_overflow): Now extern.

9720 (decode_time_components, lisp_seconds_argument): New functions.
9721 (make_time): Now static.
9722 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9723 Report an error if the time is invalid, rather than having the caller
9726 * fileio.c: Include <stat-time.h>
9727 (Fcopy_file): Copy higher-resolution time stamps.
9728 Prefer to set the time stamp via a file descriptor if that works.

9730 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9731 (Fvisited_file_modtime, Fset_visited_file_modtime):
9732 Support higher-resolution time stamps.
9734 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9736 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9738 * image.c (prepare_image_for_display, clear_image_cache)
9739 (lookup_image): Port to higer-resolution time stamps.
9741 * keyboard.c (start_polling, bind_polling_period):
9742 Check for time stamp overflow.
9743 (read_char, kbd_buffer_get_event, timer_start_idle)
9744 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9745 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9746 Port to higher-resolution time stamps. Do not assume time_t is signed.
9747 (decode_timer): New function. Timers are now vectors of length 9,
9748 not 8, to accommodate the picosecond component.
9749 (timer_check_2): Use it.
9751 * nsterm.m (select_timeout, timeval_subtract): Remove.
9752 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9753 as they're a bit more accurate and handle overflow better.
9754 (ns_select): Change prototype to be compatible with pselect.
9755 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9756 * nsterm.h (ns_select): Adjust prototype.
9758 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9759 us-resolution time stamps.
9760 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9762 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9764 * lisp.h (time_overflow): New decl.
9765 (wait_reading_process_output): First arg is now intmax_t, not int,
9766 to accommodate larger waits.
9768 * process.h (struct Lisp_Process.read_output_delay):
9769 Now counts nanoseconds, not microseconds.
9770 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9772 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9773 (wait_reading_process_output):
9774 Port to ns-resolution time stamps.
9775 (Faccept_process_output, wait_reading_process_output):
9776 Check for time stamp overflow. Do not assume time_t is signed.
9777 (select_wrapper): Remove; we now use pselect.
9778 (Fprocess_attributes): Now generates ns-resolution time stamps.
9780 * sysdep.c: Include utimens.h. Don't include utime.h
9781 or worry about struct utimbuf; gnulib does that for us now.
9782 (gettimeofday): Remove; gnulib provides a substitute.
9783 (make_timeval): New function.
9784 (set_file_times): Now sets ns-resolution time stamps.
9785 New arg FD; all uses changed.
9786 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9787 (system_process_attributes):
9788 Now returns ns-resolution time stamp. All uses changed.
9789 Check for time stamp overflow.
9791 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9792 provides a substitute now.
9794 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9795 since it guarantees struct timespec.
9796 (EMACS_TIME): Now struct timespec, so that we can support
9797 ns-resolution time stamps.
9798 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9799 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9800 (EMACS_USECS): Remove.
9801 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9802 so multiply the arg by 1000 before storing it.
9803 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9805 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9806 Port to ns-resolution time stamps.
9807 (EMACS_TIME_NEG_P): Remove; replaced by....
9808 (EMACS_TIME_SIGN): New macro.
9809 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9810 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
9811 (set_file_times, make_time, lisp_time_argument): Adjust signature.
9812 (make_timeval, make_lisp_time, decode_time_components): New decls.
9813 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9814 that it mishandled time_t overflow. You can't compare by subtracting!
9815 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9816 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9818 * term.c: Include <sys/time.h>.

9827 (w32_get_internal_run_time):
9828 Port to higher-resolution Emacs time stamps.
9829 (ltime): Now accepts single 64-bit integer, as that's more convenient
9832 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9834 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9835 for compatibility with pselect. Support ns-resolution time stamps.
9837 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9839 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9840 Check for time stamp overflow, and support ns-resolution time stamps.
9842 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9843 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9844 (timeval_subtract): Remove; no longer needed.
9845 (XTflash, XTring_bell, x_wait_for_event):
9846 Port to ns-resolution time stamps. Don't assume time_t is signed.
9848 2012-06-22 Chong Yidong <cyd@gnu.org>

9852 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9854 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9855 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9856 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9857 staticidx goes up to 1597 out of 1600 = 0x640.)
9859 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9861 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9862 Otherwise, the umask might be mistakenly 0 while handling input signals.

9883 (unwind_format_mode_line): Restore them.
9884 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9886 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9887 since tty frames can be explicitly named.
9888 (prepare_menu_bars): Likewise.
9890 * term.c (Ftty_top_frame): New function.
9892 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

9895 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9896 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9897 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9898 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
9899 (METER_1, METER_2): Simplify.
9901 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

9905 2012-06-18 Martin Rudalics <rudalics@gmx.at>
9907 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9908 gets killed during executing of this function (Bug#11665).
9909 Try to always return Qt when the buffer has been actually killed.
9910 (Vkill_buffer_query_functions): In doc-string say that functions
9911 run by this hook should not change the current buffer.
9913 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9915 Fix recently-introduced process.c problems found by static checking.

9933 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
9935 * lisp.h (eassert): Assume C89 or later.
9936 This removes the need for CHECK.
9937 (CHECK): Remove. Its comments about always evaluating its
9938 argument were confusing, as 'eassert' typically does not evaluate
9941 * coding.c (produce_chars): Use ptrdiff_t, not int.
9943 * xterm.c (x_draw_underwave): Check for integer overflow.
9944 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

10066 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
10067 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):

10118 * alloc.c (make_number) [!defined make_number]:
10119 Remove, as lisp.h always defines this now.

10129 code works fine either way, and efficiency is not a concern here,
10130 as the union type is for debugging, not for production.
10131 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10132 Use an inline function on all platforms when using the union type,
10133 since this is simpler and 'static inline' can be used portably
10135 (LISP_INITIALLY_ZERO): New macro.
10136 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
10137 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

10240 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
10242 2012-06-08 Eli Zaretskii <eliz@gnu.org>
10244 * alloc.c (allocate_vectorlike): Fix last change.

10277 * doprnt.c (doprnt): Truncate multibyte char correctly.
10278 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10279 would mishandle a string argument "Xc" if X was a multibyte
10280 character of length 2: it would truncate after X's first byte
10281 rather than including all of X.
10283 2012-06-06 Chong Yidong <cyd@gnu.org>
10285 * buffer.c (word_wrap): Doc fix.

10332 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10334 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10335 Convert pctcpu and pctmem to Lisp float properly.
10336 Let the compiler fold better, as 100.0/0x8000 is exact.
10338 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
10340 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

10347 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
10349 For a 'struct window', replace some Lisp_Object fields to
10350 bitfields where appropriate, remove unused fields.
10351 * window.h (struct window): Remove unused 'last_mark_x' and
10352 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10353 change its type from Lisp_Object to bitfield.
10354 Change type of 'force_start', 'optional_new_start',
10355 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

10362 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10363 Use 'float' consistently, rather than 'float' in most places
10364 and 'double' in a couple of places.
10366 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10368 * xdisp.c (handle_stop): Detect whether we have overlay strings
10369 loaded by testing it->current.overlay_string_index to be
10370 non-negative, instead of checking whether n_overlay_strings is
10371 positive. (Bug#11587)
10373 2012-05-31 Chong Yidong <cyd@gnu.org>
10375 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

10381 * search.c (search_buffer): Remove calls to
10382 r_alloc_inhibit_buffer_relocation, as it is now called by

10388 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10389 for the duration of call to load_charset, to avoid problems with
10390 callers of maybe_unify_char that access buffer text through C
10393 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10394 decrement the inhibition flag, instead of just setting or
10397 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10399 Remove obsolete '#define static' cruft.
10400 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10401 This #undef was "temporary" in 2000; it is no longer needed
10402 now that '#define static' has gone away.
10403 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10404 (gray_bitmap_bits): Remove; no longer needed.

10417 (safe_bcopy): Remove decl; no longer has that name.
10418 (main): Coalesce #if into single bit of code, for simplicity.

10449 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10450 Bug#9642, but explicitly check that the buffer the overlay would
10451 be moved to is live and rearrange lines to make sure that errors
10452 will not put the overlay in an inconsistent state.

10457 * w32term.c (my_bring_window_to_top): New function.
10458 (x_raise_frame): Use handle returned by DeferWindowPos, which
10459 could be different from the original one.

10469 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10471 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10472 This avoids undefined behavior that might cause the eassert
10473 to not catch an out-of-range value.
10475 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10477 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10478 Update dependencies.

10487 when referring to sectname field in printf format.
10489 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10491 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10492 Only r_alloc_inhibit_buffer_relocation needed to be added;
10493 the others were already declared.
10495 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10496 before checking whether it's out of range. Put the check inside
10498 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10500 2012-05-27 Ken Brown <kbrown@cornell.edu>
10502 * callproc.c (Fcall_process): Restore a line that was accidentally
10503 commented out in the 2011-02-13 change (bug#11547).
10505 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10507 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10508 defined on ralloc.c.
10510 * buffer.c [REL_ALLOC]: Remove prototypes of
10511 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10512 they are now on lisp.h.
10514 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10516 * search.c (search_buffer): Use it to inhibit relocation of buffer
10517 text while re_search_2 is doing its job, because re_search_2 is
10518 passed C pointers to buffer text. (Bug#11519)
10520 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10521 Update value to 24.
10523 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10524 state after an additional call to move_it_in_display_line_to, keep
10525 the values of it->max_ascent and it->max_descent found for the
10527 (pos_visible_p): Revert the comparison against bottom_y to what it
10528 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10531 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10533 Fix coding-related core dumps with gcc -ftrapv.
10534 The code was computing A - B, where A and B are pointers, and B is
10535 random garbage. This can lead to core dumps on platforms that
10536 have special pointer registers, and it also leads to core dumps on
10537 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10538 A - B only when B is initialized properly.
10539 * coding.c (coding_set_source, coding_set_destination): Return void.
10540 (coding_change_source, coding_change_destinations): New functions,
10541 with the old behaviors of coding_set_source and coding_set_destination.
10542 All callers that need an offset changed to use these new functions.
10544 2012-05-26 Glenn Morris <rgm@gnu.org>
10546 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
10548 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10550 Extend mouse support on W32 text-mode console.
10551 * xdisp.c (draw_row_with_mouse_face):
10552 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10554 * w32console.c: Include window.h.
10555 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10557 (initialize_w32_display): Initialize mouse-highlight data.
10559 * w32inevt.c: Include termchar.h and window.h.
10560 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10561 moves, call note_mouse_highlight. If help_echo changed, call
10562 gen_help_event to produce help-echo message in the echo area.
10563 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10566 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10568 * lread.c (read1): Simplify slightly to avoid an overflow warning
10569 with GCC 4.7.0 on x86-64.
10571 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10573 * bidi.c (bidi_mirror_char): Revert last change: an int is
10574 definitely wide enough here.
10576 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10578 Fix integer width and related bugs (Bug#9874).

10590 Use int, not EMACS_INT, where int is wide enough.
10591 (inhibit_garbage_collection, Fgarbage_collect):
10592 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10593 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10594 int might not be wide enough.
10595 (bidi_cache_search, bidi_cache_find, bidi_init_it)

10610 (Foverlay_recenter, last_overlay_modification_hooks_used)
10611 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10612 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10613 (validate_region): Omit unnecessary test for b <= e,
10614 since that's guaranteed by the previous test.
10615 (adjust_overlays_for_delete): Avoid pos + length overflow.
10616 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10617 (report_overlay_modification):
10618 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10619 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10620 Omit pointer cast, which isn't needed anyway, and doesn't work
10621 after the EMACS_INT -> ptrdiff_t change.
10622 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10623 * buffer.h: Adjust decls to match defn changes elsewhere.
10624 (struct buffer_text, struct buffer):
10625 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10626 Use EMACS_INT, not int, where int might not be wide enough.
10627 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10628 not int, to avoid needless 32-bit limit on 64-bit hosts.
10629 (exec_byte_code): Use tighter memory-full test, one that checks
10630 for alloca overflow. Don't compute the address of the object just
10631 before an array, as that's not portable. Use EMACS_INT, not
10632 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10633 * callint.c (Fcall_interactively):
10634 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10635 * callproc.c (call_process_kill, Fcall_process):
10636 Don't assume pid_t fits into an Emacs fixnum.
10637 (call_process_cleanup, Fcall_process, child_setup):

10645 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10646 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10647 (casify_object): Avoid integer overflow when overallocating buffer.
10648 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10649 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10650 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10651 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10652 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10653 integers are now checked earlier. All uses replaced with XINT.
10655 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10656 For CCL_MapSingle, check that content and value are in int range.
10657 (ccl_driver, Fregister_code_conversion_map):
10658 Check that Vcode_version_map_vector is a vector.
10659 (resolve_symbol_ccl_program): Check that vector header is in range.
10660 Always copy the vector, so that we can check its contents reliably
10661 now rather than having to recheck each instruction as it's being
10662 executed. Check that vector words fit in 'int'.
10663 (ccl_get_compiled_code, Fregister_ccl_program)
10664 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10665 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10666 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10667 contents are in range.
10668 (Fccl_execute_on_string): Check that status is in range.
10669 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10670 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10671 Accept and return EMACS_INT, not int, because callers can pass values
10672 out of 'int' range.

10678 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10679 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10680 avoid mishandling large integers.
10681 * character.h: Adjust decls to match defn changes elsewhere.
10682 * charset.c (load_charset_map_from_file, find_charsets_in_text)

10687 Don't assume fixnum fits in int.
10688 (load_charset_map_from_vector, Fmap_charset_chars):
10689 Remove now-unnecessary CHECK_NATNUMs.
10690 (Fdefine_charset_internal): Check ranges here, more carefully.
10691 Don't rely on undefined behavior with signed left shift overflow.
10692 Don't assume unsigned int fits into fixnum, or that fixnum fits
10693 into unsigned int. Don't require max_code to be a valid fixnum;
10694 that's not true for gb10830 4-byte on a 32-bit host. Allow
10695 invalid_code to be a cons, for the same reason. Require code_offset
10696 to be a character. Avoid int overflow if max_char is close
10698 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10699 this is intended anyway and avoids some undefined behavior.
10700 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10701 INDEX_TO_CODE_POINT, as that's what it expects.
10702 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10703 * charset.h (DECODE_CHAR): Return int, not unsigned;
10704 this is what was intended anyway, and it avoids undefined behavior.
10705 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10706 integer-overflow issues.
10707 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10708 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10709 where the argument is EMACS_INT, and this behavior is not intended.
10710 * chartab.c (Fmake_char_table, Fset_char_table_range)
10711 (uniprop_get_decoder, uniprop_get_encoder):
10712 Don't assume fixnum fits in int.
10713 * cmds.c (move_point): New function, that does the gist of
10714 Fforward_char and Fbackward_char, but does so while checking
10715 for integer overflow more accurately.
10716 (Fforward_char, Fbackward_char): Use it.
10717 (Fforward_line, Fend_of_line, internal_self_insert)
10718 (internal_self_insert):
10719 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10779 Do not attempt to compute the address of the object just before a

11524 (get_next_display_element): When the current object is exhausted,
11525 and there's something on it->stack, call set_iterator_to_next to
11526 proceed with what's on the stack, instead of returning zero.
11527 (set_iterator_to_next): If called at the end of a Lisp string,
11528 proceed to consider_string_end without incrementing string
11529 position. Don't increment display vector index past the end of
11530 the display vector. (Bug#11417)
11531 (pos_visible_p): Don't report a position visible when move_it_to
11532 stopped at the last line of window, which happens to be scanned
11533 backwards by the bidi iteration. (Bug#11464)
11535 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11537 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11538 and right-margin display specs even if the spec is invalid or we
11539 are on a TTY, and thus unable to display on the fringes.
11540 That's because the text with the property will not be displayed anyway,
11541 so we need to signal to the caller that this is a "replacing"
11542 display spec. This fixes display when the spec is invalid or we
11545 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11547 * unexaix.c (make_hdr): Fix typo in prototype.
11548 This bug broke the build on AIX. Problem reported by Gilles Pion.
11550 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11552 * keyboard.c (kbd_buffer_get_event): Read special events also in
11553 batch mode. (Bug#11415)
11555 2012-05-12 Glenn Morris <rgm@gnu.org>
11557 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11559 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11561 * lisp.mk (lisp): Add newcomment.elc.
11563 2012-05-12 Glenn Morris <rgm@gnu.org>
11565 * Makefile.in (MKDIR_P): New, set by configure.
11566 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11568 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11570 Remove unused function hourglass_started.
11571 * dispextern.h (hourglass_started):
11572 * w32fns.c (hourglass_started):
11573 * xdisp.c (hourglass_started): Remove.
11575 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11577 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11578 Update dependencies.
11580 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11582 * xgselect.c (xg_select): Put maxfds+1 into a var.
11583 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11585 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11587 2012-05-10 Dave Abrahams <dave@boostpro.com>
11589 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11590 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11592 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11594 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11595 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11596 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11597 Initialize xd_registered_buses.
11599 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11601 Untag more efficiently if USE_LSB_TAG.
11602 This is based on a proposal by YAMAMOTO Mitsuharu in
11603 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11604 For an admittedly artificial (nth 8000 longlist) benchmark on
11605 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11606 Emacs's overall text size by 1%.
11607 * lisp.h (XUNTAG): New macro.
11608 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11609 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11610 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11611 * eval.c (Fautoload):
11612 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11613 * frame.h (XFRAME): Use XUNTAG.
11615 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11616 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11617 Remove unportable assumptions about print widths of types like
11619 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11620 intptr_t when converting between pointer and integer, to avoid GCC
11621 warnings about wrong width.
11623 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11625 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11626 stack for each reader_thread, instead of defaulting to 8MB
11627 determined by the linker. This avoids failures in creating
11628 subprocesses on Windows 7, see the discussion in this thread:
11629 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11631 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11633 Fix up display of the *Minibuf-0* buffer in the mini window.
11634 * keyboard.c (read_char): Don't clear the echo area if there's no
11636 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11637 contents of *Minibuf-0*) if there's no message displayed in its stead.
11639 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11641 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11644 2012-05-06 Chong Yidong <cyd@gnu.org>
11646 * lisp.mk (lisp): Update.
11648 2012-05-05 Jim Meyering <meyering@redhat.com>
11650 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11652 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11654 * data.c (PUT_ERROR): New macro.
11655 (syms_of_data): Use it. Add new error type `user-error'.
11656 * undo.c (user_error): New function.
11657 (Fprimitive_undo): Use it.
11658 * print.c (print_error_message): Adjust print style for `user-error'.
11659 * keyboard.c (user_error): New function.
11660 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11662 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11664 Do not limit current-time-string to years 1000..9999.
11665 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11666 (Fcurrent_time_string): Support any year that is supported by the
11667 underlying localtime representation. Don't use asctime, as it
11668 has undefined behavior for years outside the range -999..9999.
11670 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11672 Fix race conditions involving setenv, gmtime, localtime, asctime.
11673 Without this fix, interrupts could mess up code that uses these
11674 nonreentrant functions, since setting TZ invalidates existing
11675 tm_zone or tzname values, and since most of these functions return
11676 pointers to static storage.
11677 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11678 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11679 Grow the critical sections to include not just invoking
11680 localtime/gmtime, but also accessing these functions' results
11681 including their tm_zone values if any, and any related TZ setting.
11682 (format_time_string): Last arg is now struct tm *, not struct tm **,
11683 so that the struct tm is saved in the critical section.
11684 All callers changed. Simplify allocation of initial buffer, partly
11685 motivated by the fact that memory allocation needs to be outside
11686 the critical section.
11688 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11690 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11691 with RESET_INTERVAL.
11693 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11694 Remove duplicated buffer name initialization.
11696 2012-05-02 Jim Meyering <jim@meyering.net>
11698 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11700 * xfns.c (x_window): Use xstrdup (Bug#11375).
11702 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11704 * xdisp.c (pos_visible_p): If already at a newline from the
11705 display string before the 'while' loop, don't walk back the glyphs
11706 from it3.glyph_row. Solves assertion violation when the display
11707 string begins with a newline (egg.el). (Bug#11367)
11709 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11711 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11714 2012-05-01 Glenn Morris <rgm@gnu.org>
11716 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11717 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11718 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11719 All were removed before 23.1.
11721 * dispnew.c: Remove HAVE_LIBNCURSES test;
11722 it is always true on relevant platforms.
11724 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11725 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11727 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11729 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11731 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11732 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11735 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11737 Do not avoid creating empty evaporating overlays (Bug#9642).
11738 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11739 That is, do not delete an evaporating overlay if it becomes
11740 empty after its bounds are adjusted to fit within its buffer.
11741 This fix caused other problems, and I'm reverting it until we get
11742 to the bottom of them.
11744 2012-04-27 Chong Yidong <cyd@gnu.org>
11746 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11748 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11750 * xdisp.c (pos_visible_p): If the window start position is beyond
11751 ZV, start the display from buffer beginning. Prevents assertion
11752 violation in init_iterator when the minibuffer window is scrolled
11753 via the scroll bar.
11755 * window.c (window_scroll_pixel_based): Likewise.
11757 2012-04-27 Chong Yidong <cyd@gnu.org>
11759 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11761 2012-04-27 Glenn Morris <rgm@gnu.org>
11763 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11764 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11766 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11768 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11769 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11771 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11773 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11774 display element, check also the underlying string or buffer
11775 character. (Bug#11341)
11777 * w32menu.c: Include w32heap.h.
11778 (add_menu_item): If the call to AppendMenuW (via
11779 unicode_append_menu) fails, disable Unicode menus only if we are
11780 running on Windows 9X/Me.
11782 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11784 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11785 (xgetint): Add missing shift for LSB tags.
11787 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11789 * keyboard.c (read_char): Don't wipe echo area for select window
11790 events: These might get delayed via `mouse-autoselect-window'
11793 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11795 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11796 manipulation of :loaded-from data.
11798 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11800 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11801 now a cons (bug#11311).
11803 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11805 Do not create empty overlays with the evaporate property (Bug#9642).
11806 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11807 if it becomes empty after its bounds are adjusted to fit within
11808 its buffer. Without this fix, in a nonempty buffer (let ((o
11809 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11810 yields an empty overlay that has the evaporate property, which is
11811 not supposed to happen.
11813 Fix minor GTK3 problems found by static checking.
11814 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11815 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11816 (struct _EmacsFixedClass, emacs_fixed_get_type):
11817 Move decls here from emacsgtkfixed.h, since they needn't be public.
11818 (emacs_fixed_get_type): Now static.
11819 (emacs_fixed_class_init): Omit unused local.
11820 (emacs_fixed_child_type): Remove; unused.

11822 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11823 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11824 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11825 (EMACS_FIXED_GET_CLASS): Remove; unused.
11826 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11828 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11829 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11831 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11833 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11834 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11835 (__malloc_size_t, __malloc_ptrdiff_t):
11836 Remove. All uses removed, replaced by the definiens if needed,
11837 since we can assume C89 or better now.
11838 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

11845 (special_realloc, _realloc_internal_nolock, _realloc_internal)
11846 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11847 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11848 Define using prototypes, not old style.
11849 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11850 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11851 (align): Don't assume that signed integer overflow wraps around.
11852 Omit unused local var.
11853 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

11855 Omit no-longer-needed casts.
11856 (valloc): Use getpagesize, not __getpagesize.
11857 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11858 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11860 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11862 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11864 Move functions from C to Lisp. Make non-blocking method calls
11865 the default. Implement further D-Bus standard interfaces.

11909 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
11910 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
11911 Do not assume ptrdiff_t is the same width as 'int'.
11913 * alloc.c: Handle unusual debugging option combinations.
11914 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
11915 since the two debugging options are incompatible.
11916 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
11918 (mem_init, mem_insert, mem_insert_fixup):
11919 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

11926 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11928 * sysdep.c [__FreeBSD__]: Minor cleanups.
11929 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11930 Use Emacs indenting style more consistently. Avoid some casts.
11931 Use 'double' consistently rather than mixing 'float' and 'double'.
11933 2012-04-21 Eduard Wiebe <usenet@pusto.de>
11935 * sysdep.c (list_system_processes, system_process_attributes):

11949 * print.c (print_preprocess): Only check print_depth if print-circle
11951 (print_object): Check for cycles even when print-circle is nil and

11954 2012-04-20 Chong Yidong <cyd@gnu.org>
11956 * process.c (wait_reading_process_output): If EIO occurs on a pty,

11970 row, return zero immediately.
11971 (try_cursor_movement): If inside continuation line, don't back up
11972 farther than the first row after the header line, if any.
11973 Don't consider the header-line row as "partially visible", even if
11974 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
11976 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

11985 * Makefile.in (C_WARNINGS_SWITCH): Remove.
11986 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
11987 (ALL_CFLAGS): Use new macros rather than old.
11988 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
11989 * regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore
11990 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
11991 -Wunused-result, -Wunused-variable. This should go away once
11992 the Emacs and Gnulib regex code is merged.
11993 (xmalloc, xrealloc): Now static.
11995 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

12012 New extern decls, to avoid calling undeclared functions.
12013 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
12014 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12015 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12016 (NEED_MEM_INSERT): New macro.
12017 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12018 Remove one incorrect comment and fix another.
12020 Fix minor ralloc.c problems found by static checking.
12021 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

12026 Improve ralloc.c interface checking.
12027 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
12028 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
12029 (r_alloc_free) [REL_ALLOC]: Move decls from here ...

12032 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
12033 Remove decls. This fixes an "It stinks!".
12035 * alloc.c (which_symbols): Fix alignment issue / type clash.
12037 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
12039 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
12040 (struct Lisp_Misc_Any): Likewise.
12041 (struct Lisp_Free): Likewise.
12042 * alloc.c (union aligned_Lisp_Symbol): Define.

12052 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
12053 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
12054 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12055 * s/netbsd.h, s/sol2-6.h:
12056 Remove definition of GC_MARK_STACK, since the default now works.
12057 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12058 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12059 no longer the default.
12060 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12062 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
12064 * lread.c (lisp_file_lexically_bound_p):
12065 Fix hang at ";-*-\n" (bug#11238).
12067 2012-04-14 Eli Zaretskii <eliz@gnu.org>
12069 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
12070 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

12079 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
12081 2012-04-13 Reuben Thomas <rrt@sc3d.org>
12083 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
12085 2012-04-11 Daniel Colascione <dancol@dancol.org>
12087 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12088 against is gone. It's better to use vfork now so that when Cygwin
12089 gains a new, working vfork, we use it automatically (bug#10398).
12091 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
12093 * window.c (save_window_save): Obey window-point-insertion-type.

12109 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
12111 * w32.c (w32_delayed_load): Record the full path of the library
12112 being loaded (bug#10424).
12114 2012-04-09 Glenn Morris <rgm@gnu.org>
12116 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12117 not just in the obarray, before snarfing them. (Bug#11036)
12119 * Makefile.in ($(leimdir)/leim-list.el):
12120 Pass EMACS rather than BUILT_EMACS.
12122 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
12124 * process.c (make_process):
12125 * process.h: Add integer `gnutls_handshakes_tried' member to
12128 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.

12134 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12135 attempts per process (connection).
12137 2012-04-09 Chong Yidong <cyd@gnu.org>
12139 * eval.c (Fuser_variable_p, user_variable_p_eh)
12140 (lisp_indirect_variable): Functions deleted.
12141 (Fdefvar): Caller changed.
12143 * callint.c (Finteractive, Fcall_interactively):
12144 * minibuf.c (Fread_variable): Callers changed.
12146 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12148 * xdisp.c (set_cursor_from_row): If the display string appears in
12149 the buffer at position that is closer to point than the position
12150 after the display string, display the cursor on the first glyph of
12151 the display string. Fixes cursor display when a 'display' text
12152 property immediately follows invisible text. (Bug#11094)
12154 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12156 composite.c: use 'double' consistently
12157 * composite.c (get_composition_id): Use 'double' consistently
12158 instead of converting 'float' to 'double' and vice versa; this is
12159 easier to understand and avoids a GCC warning.
12161 2012-04-09 Glenn Morris <rgm@gnu.org>
12163 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12164 preparation for dumping it with emacs. (Bug#4789)
12165 (leimdir): New variable.

12185 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12186 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12187 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12188 objects, as mark_maybe_pointer will catch them otherwise.
12189 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12190 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12197 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12199 Support building on MS-Windows with libxml2.
12201 * makefile.w32-in (OBJ2): Add xml.$(O).
12202 (GLOBAL_SOURCES): Add xml.c.
12203 ($(BLD)/xml.$(O)): New dependency list.
12205 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12206 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12207 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12208 [!WINDOWSNT]: New macros.
12209 (init_libxml2_functions, libxml2_loaded_p): New functions.
12210 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12211 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12212 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12213 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12215 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12216 Call init_libxml2_functions before calling libxml2 functions.
12217 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12219 * emacs.c: Don't include libxml/parser.h.
12220 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12221 xmlCleanupParser directly.
12223 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12225 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12227 * indent.c (Fvertical_motion): If there is a display string at
12228 point, use it.vpos to compute how many lines to backtrack after
12229 move_it_to point. (Bug#11133)
12231 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12233 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12234 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12235 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12236 macros related to unification of CJK characters. For the details,
12237 see the discussion following the message here:
12238 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12240 2012-04-04 Chong Yidong <cyd@gnu.org>
12242 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12244 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12246 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12247 instead of alloca. (Bug#11138)
12249 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12251 * w32menu.c (is_simple_dialog): Properly check lisp types.
12254 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12256 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12257 position we get to after a call to move_it_to fails the
12258 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12259 only if we wind up in a string from display property. (Bug#11063)
12261 * window.c (Fdelete_other_windows_internal): Invalidate the row
12262 and column information about mouse highlight, so that redisplay
12263 restores it after reallocating the glyph matrices. (Bug#7464)
12265 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12266 string comes from a `display' text property, use the buffer
12267 position of that property as if we actually saw that position in
12269 (move_it_by_lines): Remove the assertion that
12270 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12271 violated when there's a before-string at the beginning of a line.
12274 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12276 * xdisp.c (append_space_for_newline): If the default face was
12277 remapped, use the remapped face for the appended newline.
12278 (extend_face_to_end_of_line): Use the remapped default face for
12279 extending the face to the end of the line.
12280 (display_line): Call extend_face_to_end_of_line when the default
12281 face was remapped. (Bug#11068)
12283 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12285 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12287 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

12303 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12304 (command_loop_1): Use it; inhibit selection update for
12305 handle-select-window too (Bug#8996).

12309 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12311 2012-03-25 Kenichi Handa <handa@m17n.org>
12313 * dispextern.h (struct glyph): Change the bit length of
12314 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12316 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12318 * s/ms-w32.h (tzname): Include time.h before redirecting to

12323 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12326 * xterm.c (XTread_socket): Only modify handling_signal if
12327 !SYNC_INPUT. (Bug#11080)
12329 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12331 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12332 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12333 when fetching a multibyte character consumes more bytes than
12334 CHAR_BYTES returns, due to unification of CJK characters in
12335 string_char. (Bug#11073)
12337 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12339 * process.c (wait_reading_process_output): Handle pty disconnect
12340 by refraining from sending oneself a SIGCHLD (bug#10933).
12342 2012-03-22 Chong Yidong <cyd@gnu.org>
12344 * dispextern.h (struct it): New member string_from_prefix_prop_p.
12346 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12347 Mark string as coming from a prefix property.
12348 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12349 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12351 2012-03-21 Chong Yidong <cyd@gnu.org>
12353 * xfaces.c (Vface_remapping_alist): Doc fix.
12355 2012-03-20 Eli Zaretskii <eliz@gnu.org>

12369 it fit in a valid range (Bug#11003).
12371 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12373 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12374 that is not from display property, accept the row as a "cursor
12375 row" if one of the string's character has a non-nil `cursor'
12376 property. Fixes cursor positioning when there are newlines in
12377 overlay strings, e.g. in icomplete.el. (Bug#11035)
12379 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12381 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
12383 2012-03-12 Chong Yidong <cyd@gnu.org>
12385 * eval.c (inhibit_lisp_code): Rename from
12386 inhibit_window_configuration_change_hook; move from window.c.
12388 * xfns.c (unwind_create_frame_1, Fx_create_frame):
12389 * window.c (run_window_configuration_change_hook)
12390 (syms_of_window): Callers changed.
12392 2012-03-11 Chong Yidong <cyd@gnu.org>
12394 * keymap.c (Fkey_description): Doc fix (Bug#9700).
12396 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
12398 2012-03-10 Chong Yidong <cyd@gnu.org>
12400 * frame.c (other_visible_frames): Don't assume the selected frame
12401 is visible (Bug#10955).
12403 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
12405 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
12407 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
12409 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
12410 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12413 2012-03-03 Glenn Morris <rgm@gnu.org>
12415 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12417 2012-03-02 Eli Zaretskii <eliz@gnu.org>
12419 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
12420 position past the first glyph_row that ends at ZV. (Bug#10902)
12421 (redisplay_window, next_element_from_string): Fix typos in
12423 (redisplay_window): Pass to move_it_vertically the margin in
12424 pixels, not in screen lines.
12426 2012-03-02 Glenn Morris <rgm@gnu.org>
12428 * buffer.c (buffer-list-update-hook): Doc fix.
12430 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12432 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12433 push_it before setting up the iterator for the first overlay
12434 string, even if we have an empty string loaded.
12435 (next_overlay_string): If there's an empty string on the iterator
12436 stack, pop the stack. (Bug#10903)
12438 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12440 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12441 Suggested by Stefan Monnier in
12442 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12443 * alloc.c (widen_to_Lisp_Object): New static function.
12444 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12445 and widening them to Lisp_Objects. This would work even if
12446 USE_LSB_TAG is defined and wide integers are used, which might
12447 happen in a future version of Emacs.
12449 2012-02-25 Chong Yidong <cyd@gnu.org>
12451 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

12456 before saving to clipboard manager.
12458 2012-02-24 Chong Yidong <cyd@gnu.org>
12460 * keyboard.c (process_special_events): Handle all X selection
12461 requests in kbd_buffer, not just the next one (Bug#8869).
12463 2012-02-23 Chong Yidong <cyd@gnu.org>
12465 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12466 call when setting menu-bar-lines and tool-bar-lines parameters.
12467 (unwind_create_frame_1): New helper function.
12469 * window.c (inhibit_window_configuration_change_hook): New var.

12488 when computing $valmask.
12490 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12491 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12492 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12493 It's useless in that case, and it can cause problems on hosts
12494 that allocate halves of EMACS_INT values separately.
12495 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12496 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12497 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12498 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12499 it avoids undefined behavior on hosts where shifting right by more
12500 than the word width has undefined behavior.
12502 2012-02-19 Chong Yidong <cyd@gnu.org>
12504 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12505 (Funhandled_file_name_directory, Ffile_name_as_directory)
12506 (Fdirectory_file_name, Fexpand_file_name)
12507 (Fsubstitute_in_file_name): Protect against invalid file handler
12508 return values (Bug#10845).

12524 2012-02-15 Chong Yidong <cyd@gnu.org>
12526 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

12542 2012-02-12 Chong Yidong <cyd@gnu.org>
12544 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12545 as that creates a dangerous corner case.
12547 * window.c (Fdelete_window_internal): Invalidate the mouse
12548 highlight (Bug#9904).
12550 2012-02-12 Glenn Morris <rgm@gnu.org>

12580 2012-02-07 Chong Yidong <cyd@gnu.org>
12582 * buffer.c (Fbuffer_local_variables)
12583 (buffer_lisp_local_variables): Handle unbound vars correctly;
12584 don't let Qunbound leak into Lisp.
12586 2012-02-07 Glenn Morris <rgm@gnu.org>
12588 * image.c (Fimagemagick_types): Doc fix.
12590 * image.c (imagemagick-render-type): Change it from a lisp object
12591 to an integer. Move the doc here from the lisp manual.

12621 before BEGV. (Bug#10696)
12623 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
12625 Handle overflow when computing char display width (Bug#9496).
12626 * character.c (char_width): Return EMACS_INT, not int.
12627 (char_width, c_string_width): Check for overflow when
12628 computing the width; this is possible now that individual
12629 characters can have unbounded width. Problem introduced
12630 by merge from Emacs 23 on 2012-01-19.

12654 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to

12661 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
12662 first 2 arguments are identical. This makes inserting large
12663 output from a subprocess an order of magnitude faster on
12664 MS-Windows, where all sbrk'ed memory is always contiguous.

13302 behave as if the cursor position were at the window margin.
13304 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13305 and the cursor position is out of bounds, behave as if the cursor
13306 position were at the window margin. (Bug#10075)

13332 compute_line_metrics.
13333 (compute_line_metrics): Call row_hash, instead of computing the
13336 * dispnew.c (verify_row_hash): Call row_hash for computing the
13337 hash code of a row, instead of duplicating code from xdisp.c.
13339 * dispextern.h (row_hash): Add prototype.
13341 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

13447 The trivial performance wins aren't worth the portability hassles; see
13448 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
13450 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

13524 (window_box_width, window_box_left, window_box_left_offset)
13525 (window_box_right, window_box_right_offset): Declare extern.
13526 Otherwise, these inline functions do not conform to C99 and
13527 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13528 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13529 * intervals.c (adjust_intervals_for_insertion)

13532 (static_offset_intervals): Remove.
13533 (offset_intervals): Rewrite using the old contents of
13534 static_offset_intervals. The old version didn't conform to C99
13535 because an extern inline function contained a reference to an
13536 identifier with static linkage.

13557 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
13558 (Fwindow_vscroll): Doc fix.

13825 * keyboard.c (test_undefined): New function (bug#9751).
13826 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13828 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13830 * sysdep.c (init_sys_modes): Fix the check for the controlling
13831 terminal (Bug#6649).
13833 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13835 * dispextern.h (struct bidi_it): New member next_en_type.
13837 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13838 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13839 current character, check also for next_en_type being WEAK_EN.
13840 (bidi_resolve_weak): Don't enter the expensive loop if the current
13841 position is before next_en_pos. Record the bidi type of the first
13842 non-ET, non-BN character we find, in addition to its position.
13843 (bidi_level_of_next_char): Invalidate next_en_type when
13844 next_en_pos is over-stepped.
13846 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13848 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13849 * editfns.c: Rewrite current-time-zone so that it invokes
13850 the equivalent of (format-time-string "%Z") to get the time zone name.
13851 This fixes a bug when the time zone name contains characters that
13852 need converting from the system time locale to Emacs internal format.
13853 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13854 that patch fixed format-time-string to do the conversion, but
13855 I forgot to fix current-time-zone.
13856 (format_time_string): New function, containing most of
13857 what Fformat_time_string used to contain.
13858 (Fformat_time_string): Rewrite in terms of format_time_string.
13859 This doesn't change this function's behavior.
13860 (current-time-zone): Rewrite to use format_time_string.
13861 This fixes the bug reported by Michael Schierl in
13862 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13863 Jason Rumney's 2007-06-07 change worked around this bug, but
13865 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13867 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13869 * xdisp.c (start_display): If the character at POS is displayed
13870 via a display vector, reset IT->current.dpvec_index to zero.
13871 (try_window_reusing_current_matrix): If a line ends in a display
13872 vector or the next line starts in a display vector, continue
13873 redrawing the window even though the character position of
13874 start_row was reached.
13877 2011-10-18 Chong Yidong <cyd@gnu.org>
13879 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13880 with nobreak-char-display too.
13882 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13884 Fix part 3 of bug#9771.
13885 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13886 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13887 non-neutral characters if the current character is a paragraph
13888 separator (a.k.a. Newline). This avoids running the same
13889 expensive loop twice, once when we consume the preceding newline
13890 and the other time when the line actually needs to be displayed.
13891 Avoid the loop when we see neutrals on the base embedding level
13892 following a character whose directionality is the same as the
13893 paragraph's. This avoids running the expensive loop when a line
13894 ends in a long sequence of neutrals, like control characters.
13895 Add assertion against STRONG_AL type. Slightly rearrange code
13896 that determines the type of a neutral given the first non-neutral
13898 (bidi_level_of_next_char): Set next_en_pos to zero when
13899 invalidating its info.
13901 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13903 * xdisp.c (push_display_prop): Determine whether to record string
13904 or buffer position by IT->string, not by IT->method. Allow
13905 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13906 (move_it_vertically_backward): Don't look for character position
13907 immediately after the newline when in a continuation line.
13910 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13912 * window.c (coordinates_in_window): Rewrite and delabelize
13913 vertical border check. (Bug#5357) (Bug#9618)
13915 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13917 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13918 errors in XSetWindowBorder (bug#9310).
13920 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13922 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13923 avoid crash when xmalloc overrun checking is enabled.
13925 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13927 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13928 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13929 cursor motion with <left> and <right> arrow keys.
13931 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13932 some callers set that themselves.
13934 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13936 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13937 display string and the previous row comes from the same string and
13938 is empty. (Bug#9739) (Bug#9738)
13940 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13942 * doc.c (get_doc_string): Encode file name (bug#9735).
13944 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13946 * bidi.c (bidi_level_of_next_char):
13947 * xdisp.c (get_visually_first_element): Remove old incorrect
13948 comments regarding the Unicode Line Separator character.
13950 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13952 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13954 * alloc.c (Fgc_status): Do not access beyond zombies array
13955 boundary if nzombies > MAX_ZOMBIES.
13956 * alloc.c (dump_zombies): Add missing format specifier.
13958 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13960 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13961 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13963 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13964 Some packages use them to denote characters with modifiers.
13966 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13968 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13969 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13970 matching a pp-number. Rename parameter var to var1.
13972 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13974 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13976 2011-10-08 Glenn Morris <rgm@gnu.org>
13978 * callint.c (Fcall_interactively): Give a more explicit error for the
13979 'c' case with a non-character input. (Bug#8479)
13981 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13983 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13985 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13986 lines that are hscrolled on the left.
13988 * dispnew.c (buffer_posn_from_coords): Account for a possible
13989 presence of header-line. (Bug#4426)
13991 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13993 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13994 Don't advertise functionality which we discourage or doesn't work.
13996 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13998 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13999 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14000 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14001 this makes Emacs dump core during garbage collection on rare
14002 occasions. sizeof is obviously inferior to offsetof here, so
14003 stick with offsetof.
14004 (GC_POINTER_ALIGNMENT): New macro.
14005 (mark_memory): Omit 3rd (offset) arg; caller changed.
14006 Don't assume EMACS_INT alignment is the same as pointer alignment.
14008 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14010 * keyboard.c (read_key_sequence_remapped): New var.
14011 (read_key_sequence): Compute remapping in the right buffer.
14012 (command_loop_1): Use read_key_sequence's remapping directly.
14014 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14016 * dired.c (file_name_completion): Don't expand file name.
14017 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14018 before checking file name handler.
14020 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14021 they've been requested explicitly (bug#9591).
14023 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14025 * keymap.c (Fsingle_key_description): Use make_specified_string
14026 instead of build_string to build string from push_key_description.
14029 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14031 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14032 This fixes a Y2038 bug on 64-bit hosts.
14033 * buffer.c (reset_buffer):
14034 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14035 (Fclear_buffer_auto_save_failure):
14036 Use 0, not -1, to represent an unset failure time, since time_t
14037 might not be signed.
14039 Remove dependency on glibc malloc internals.
14040 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14041 Move back here from lisp.h, but with their new implementations.
14042 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14043 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14044 * charset.c (charset_table_init): New static var.
14045 (syms_of_charset): Use it instead of xmalloc. This removes a
14046 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14047 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14048 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14049 Move back to alloc.c.
14050 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14051 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14053 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14055 * nsterm.m (windowDidResize): Call x_set_window_size only when
14056 ns_in_resize is true. Otherwise set pixelwidth/height and
14057 call change_frame_size (Bug#9628).
14059 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14061 Port --enable-checking=all to Fedora 14 x86-64.
14062 * charset.c (syms_of_charset): Also account for glibc malloc's
14063 internal overhead when calculating the initial malloc maximum.
14065 Port --enable-checking=all to Fedora 14 x86.
14066 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14068 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14069 (overrun_check_realloc, overrun_check_free):
14070 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14071 That way, xmalloc returns a properly-aligned pointer even if
14072 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14073 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14074 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14075 into account when calculating the initial malloc maximum.
14076 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14077 Move here from alloc.c, so that charset.c can use it too.
14078 Properly align; the old code wasn't right for common 32-bit hosts
14079 when configured with --enable-checking=all.
14080 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14081 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14083 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14085 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14088 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14090 * xdisp.c (compute_display_string_end): If there's no display
14091 string at CHARPOS, return -1.
14093 * bidi.c (bidi_fetch_char): When compute_display_string_end
14094 returns a negative value, treat the character as a normal
14095 character not covered by a display string. (Bug#9624)
14097 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14099 * lread.c (Fread_from_string): Fix typo in docstring.
14101 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14103 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14104 newline, reseat the iterator instead of bidi-iterating there one
14105 character at a time. (Bug#9610)
14106 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14107 TO_CHARPOS if the bidi iterator is at base embedding level.
14109 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14111 * lread.c (readevalloop): Use correct code for NBSP.
14112 (read1): Likewise. (Bug#9608)
14114 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14116 * dbusbind.c (Fdbus_register_signal): When service is not
14117 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14119 2011-09-25 Glenn Morris <rgm@gnu.org>
14121 * buffer.c (truncate-lines): Doc fix.
14123 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14125 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14126 (Fset_window_next_buffers): Doc fix.
14128 2011-09-24 Glenn Morris <rgm@gnu.org>
14130 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14132 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14134 Fix minor problems found by static checking.
14135 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14136 * indent.c (Fvertical_motion): Fix == vs = typo.
14138 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14140 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14141 Default value is now t. Doc fix.
14143 * indent.c (Fvertical_motion): Compute and apply the overshoot
14144 logic when moving up, not only when moving down. Fix the
14145 confusing name and values of the it_overshoot_expected variable;
14146 logic changes accordingly. (Bug#9254) (Bug#9549)
14148 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14149 CHARPOS is covered by a display string which includes newlines.
14150 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14151 is covered by a display string with embedded newlines.
14153 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14155 * dbusbind.c (Fdbus_register_signal): Add match rule to
14156 Vdbus_registered_objects_table. (Bug#9581)
14157 (Fdbus_register_method, Vdbus_registered_objects_table):
14160 2011-09-24 Jim Meyering <meyering@redhat.com>
14162 do not ignore write error for any output size
14163 The previous change was incomplete.
14164 While it makes emacs --batch detect the vast majority of stdout
14165 write failures, errors were still ignored whenever the output size is
14166 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14167 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14168 && echo FAIL: ignored write error
14169 FAIL: ignored write error
14170 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14171 && echo FAIL: ignored write error
14172 FAIL: ignored write error
14173 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14175 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14177 * emacs.c (Fkill_emacs): In noninteractive mode exit
14178 non-successfully if a write error occurred on stdout. (Bug#9574)
14180 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14182 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14185 * dispextern.h (struct it): Update the comment documenting what
14188 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14190 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14191 a display string, extend search for cursor position to end of row.
14192 (find_row_edges): If the row ends in a newline from a display
14193 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14194 Handle the case of a display string with multiple newlines.
14195 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14196 non-empty line. Fixes confusing cursor motion with arrow keys at
14197 the beginning of a line that starts with whitespace.
14199 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14201 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14204 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14206 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14207 boolean (Bug#9154).
14209 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14211 * xdisp.c (display_line): Record maximum and minimum buffer
14212 positions even if no glyphs were produced (e.g., by a zero-width
14213 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14214 buffer positions that will be removed from the glyph row because
14216 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14217 column is beyond frame width: don't subtract 1 "pixel" when
14218 computing width of the stretch.
14219 (reseat_at_next_visible_line_start): Undo the change made on
14220 2011-09-17 that saved paragraph information and restored it after
14221 the call to `reseat'. (Bug#9545)
14223 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14225 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14226 and turn window cursor on if cleared (Bug#9415).
14228 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14230 * search.c (boyer_moore): Take unibyte characters from pattern
14231 literally. (Bug#9458)
14233 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14235 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14237 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14239 Fix minor problem found by static checking.
14240 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14241 initialized, to pacify gcc -Wuninitialized.
14243 * fileio.c: Report proper errno when syscall falls.
14244 (Finsert_file_contents): Save and restore errno,
14245 so that report_file_error outputs the correct diagnostic.
14246 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14248 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14250 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14252 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14254 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14255 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14257 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14259 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14260 about the current paragraph and restore it after the call to reseat.
14262 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14263 (bidi_find_paragraph_start): Search back for paragraph beginning
14264 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14265 (bidi_move_to_visually_next): Only trigger paragraph-related
14266 computations when the last character is a newline or at EOB, not
14267 just any NEUTRAL_B. (Bug#9470)
14269 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14270 truncated lines if point is covered by a display string. (Bug#9524)
14272 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14274 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14275 (cons_to_x_long): New function.
14276 (lisp_data_to_selection_data): Use it. Correct the test for
14277 short-versus-long data; it was negated. Break out of vector
14278 loop, for efficiency, when a long datum is discovered.
14280 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14282 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14284 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14286 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14287 GCC PR/17406) by declaring this function with external scope.
14289 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14291 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14292 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14294 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14296 * editfns.c (Fformat): Correctly handle text properties on "%%".
14298 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14300 * xterm.c (x_draw_composite_glyph_string_foreground):
14301 * w32term.c (x_draw_composite_glyph_string_foreground):
14302 * term.c (encode_terminal_code):
14303 * composite.c (composition_update_it, get_composition_id):
14304 * xdisp.c (get_next_display_element)
14305 (fill_composite_glyph_string): Add comments about special meaning
14306 of TAB characters in a composition.
14308 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14310 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14311 This occurs when processing a multibyte format.
14312 Problem reported by Wolfgang Jenker.
14314 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14316 * xdisp.c (try_cursor_movement): Only check for exact match if
14317 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14319 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14321 Remove unused external symbols.
14322 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14323 * xdisp.c (calc_pixel_width_or_height): Now static.
14324 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14325 * indent.c (check_display_width):
14326 * w32term.c: Fix comment to match code.
14327 * xterm.c, xterm.h (x_catching_errors): Remove.
14329 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14331 * xselect.c: Use signed conversions more consistently (Bug#9498).
14332 (selection_data_to_lisp_data): Assume incoming selection data are
14333 signed integers, not unsigned. This is to be consistent with
14334 outgoing selection data, which was modified to use signed integers
14335 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14336 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14337 expects long, not unsigned long.
14339 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14341 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14342 computation of loop end. Reported by Johan Bockgård
14345 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14347 * frame.c (Fother_visible_frames_p): Function deleted.
14349 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14351 * indent.c (compute_motion): Process display vector front to back
14352 rather than the other way around. (Bug#2496)
14354 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14356 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14358 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14360 * minibuf.c (Fread_from_minibuffer): Doc fix.
14362 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14364 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14365 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14367 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14369 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14370 value for non-existent files.
14372 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14374 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14375 set its "size" to -1. This will set the modtime_size field of
14376 the corresponding buffer to -1, which is what
14377 verify-visited-file-modtime expects for files that do not exist.
14380 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14382 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14384 * lisp.h: ... from here. push_key_description is no longer
14385 defined in keyboard.c, so its declaration should not be in
14386 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14387 logically belongs with push_key_description.
14389 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14391 * buffer.h: Include <sys/types.h> instead of <time.h>.
14392 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14393 Problem reported by Herbert J. Skuhra.
14395 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14397 * xml.c (parse_region): Make the parsing work for
14398 non-comment-starting XML files again (bug#9144).
14400 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14402 * image.c (gif_load): Fix calculation of bottom and right corner.
14405 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14407 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14408 redisplay in small windows.
14410 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14412 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14414 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14416 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14417 Operate on live windows only.
14419 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14421 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14423 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14425 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14426 only under bidi iteration.
14428 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14430 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14432 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14434 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14435 Without this fix, the command to link temacs failed due to an
14436 undefined symbol __builtin_isnan. This is because
14437 /usr/include/iso/math_c99.h #defines isnan(x) to
14438 __builtin_isnan(x), but the bundled gcc, which identifies itself
14439 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14441 * floatfns.c (isnan): #undef, and then #define to a clone of
14443 (Fisnan): Always define, since it's always available now.
14444 (syms_of_floatfns): Always define isnan at the Lisp level.
14446 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14448 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14450 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14452 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14453 The previous code assumed that file offsets (off_t values) fit in
14454 EMACS_INT variables, which is not true on typical 32-bit hosts.
14455 The code messed up by falsely reporting buffer overflow in cases
14456 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14457 when "big" contains more than 2**29 bytes, even though this
14458 inserts just one byte and does not overflow the buffer.
14459 (Finsert_file_contents): Store file offsets as off_t
14460 values, not as EMACS_INT values. Check for overflow when
14461 converting between EMACS_INT and off_t. When checking for
14462 buffer overflow or for overlap, take the offsets into account.
14463 Don't use EMACS_INT for small values where int suffices.
14464 When checking for overlap, fix a typo: ZV was used where
14465 ZV_BYTE was intended.
14466 (Fwrite_region): Don't assume off_t fits into 'long'.
14467 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14469 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14471 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14473 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14475 sprintf-related integer and memory overflow issues (Bug#9412).
14477 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14478 (esprintf, exprintf, evxprintf): New functions.
14479 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14480 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14481 (modify_event_symbol): Do not assume that the length of
14482 name_alist_or_stem is safe to alloca and fits in int.
14483 (Fexecute_extended_command): Likewise for function name and binding.
14484 (Frecursion_depth): Wrap around reliably on integer overflow.
14485 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14486 since some callers pass EMACS_INT values.
14487 (Fsingle_key_description): Don't crash if symbol name contains more
14488 than MAX_ALLOCA bytes.
14489 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14490 (get_minibuffer): Arg is now EMACS_INT, not int.
14491 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14492 (esprintf, exprintf, evxprintf): New decls.
14493 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14495 * dbusbind.c (signature_cat): New function.
14496 (xd_signature, Fdbus_register_signal):
14497 Do not overrun buffer; instead, report string overflow.
14499 * dispnew.c (add_window_display_history): Don't overrun buffer.
14500 Truncate instead; this is OK since it's just a log.
14502 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14503 even if the time zone offset is outlandishly large.
14504 Don't mishandle offset == INT_MIN.
14506 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14507 when creating daemon; the previous buffer-overflow check was incorrect.
14509 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14510 which has the guts of the old verror function.
14512 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14513 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14515 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14516 (font_unparse_xlfd): Don't blindly alloca long strings.
14517 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14518 fits in int, when using sprintf. Use single snprintf to count
14519 length of string rather than counting it via multiple sprintfs;
14520 that's simpler and more reliable.
14521 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14522 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14523 sprintf, in case result does not fit in int.
14525 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14526 (fontset_from_font): Print it.
14528 * frame.c (tty_frame_count): Now printmax_t, not int.
14529 (make_terminal_frame, set_term_frame_name): Print it.
14530 (x_report_frame_params): In X, window IDs are unsigned long,
14531 not signed long, so print them as unsigned.
14532 (validate_x_resource_name): Check for implausibly long names,
14533 and don't assume name length fits in 'int'.
14534 (x_get_resource_string): Don't blindly alloca invocation name;
14535 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14538 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14539 (xg_check_special_colors, xg_set_geometry):
14540 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14542 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14543 Use esprintf, not sprintf, in case result does not fit in int.
14545 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14546 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14547 it as a large positive number.
14548 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14549 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14551 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14552 in case result does not fit in int.
14554 * print.c (float_to_string): Detect width overflow more reliably.
14555 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14556 buffer overrun. Don't assume list length fits in 'int'. Treat
14557 print length of 0 as 0, not as infinity; to be consistent with other
14558 uses of print length in this function. Don't overflow print length
14559 index. Don't assume hash table size fits in 'long', or that
14560 vectorlike size fits in 'unsigned long'.
14562 * process.c (make_process): Use printmax_t, not int, to format
14563 process-name gensyms.
14565 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14567 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14568 to avoid potential buffer overrun.
14570 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14571 if X resource line is longer than 512 bytes.
14573 * xfns.c (x_window): Make sprintf buffer a bit bigger
14574 to avoid potential buffer overrun.
14576 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14578 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14580 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14582 Integer overflow fixes for scrolling, etc.
14583 Without these, Emacs silently mishandles large integers sometimes.
14584 For example, "C-u 4294967297 M-x recenter" was treated as if
14585 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14587 * xdisp.c (try_window_id): Check Emacs fixnum range before
14588 converting to 'int'.
14590 * window.c (window_scroll_line_based, Frecenter):
14591 Check that an Emacs fixnum is in range before assigning it to 'int'.
14592 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14593 values converted from Emacs fixnums.
14594 (Frecenter): Don't wrap around a line count if it is out of 'int'
14595 range; instead, treat it as an extreme value.
14596 (Fset_window_configuration, compare_window_configurations):
14597 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14599 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14600 that can exceed INT_MAX. Check that EMACS_INT value is in range
14601 before assigning it to the (possibly-narrower) index.
14602 (match_limit): Don't assume that a fixnum can fit in 'int'.
14604 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14607 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14608 (Fvertical_motion): Don't wrap around LINES values that don't fit
14609 in 'int'. Instead, treat them as extreme values. This is good
14610 enough for windows, which can't have more than INT_MAX lines anyway.
14612 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14614 * Require libxml/parser.h to avoid compilation warning.
14616 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14618 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14619 since this reportedly can destroy thread storage.
14621 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14623 * syntax.c (find_defun_start): Update all cache variables if
14624 exiting early (Bug#9401).
14626 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14628 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14630 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14631 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14632 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14634 * term.c (tty_append_glyph): New function.
14635 (produce_stretch_glyph): Static function and its prototype deleted.
14637 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14640 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14642 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14643 when checking :margin (Bug#9390).
14644 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14645 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14646 so that the name doesn't mislead. All uses changed.
14648 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14650 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14653 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14655 * xdisp.c (move_it_to): Don't bail out early when reaching
14656 position beyond to_charpos, if we are scanning backwards.
14657 (move_it_vertically_backward): When DY == 0, make sure we get to
14658 the first character in the line after the newline.
14660 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14662 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14663 (ccl_driver): Do not generate an out-of-range pointer.
14664 (Fccl_execute_on_string): Remove unnecessary check for
14665 integer overflow, noted by Stefan Monnier in
14666 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14667 Remove a FIXME that didn't need fixing.
14668 Simplify the newly-introduced buffer reallocation code.
14670 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14672 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14674 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14676 Integer and memory overflow issues (Bug#9196).
14678 * doc.c (get_doc_string): Rework so that
14679 get_doc_string_buffer_size is the actual buffer size, rather than
14680 being 1 less than the actual buffer size; this makes xpalloc more
14683 * image.c (x_allocate_bitmap_record, cache_image):
14684 * xselect.c (Fx_register_dnd_atom):
14685 Simplify previous changes by using xpalloc.
14687 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14688 since either will do and ptrdiff_t is convenient with xpalloc.
14690 * charset.c (charset_table_size)
14691 (struct charset_sort_data.priority): Now ptrdiff_t.
14692 (charset_compare): Don't overflow if priorities differ greatly.
14693 (Fsort_charsets): Don't assume list length fits in int.
14694 Check for size-calculation overflow when allocating sort data.
14695 (syms_of_charset): Allocate an initial charset table that is
14696 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14698 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14700 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14701 The actual value is always <= INT_MAX, and leaving it unsigned made
14702 overflow checking harder.
14704 * dispextern.h (struct glyph_matrix.rows_allocated)
14705 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14706 with xpalloc. The values are still always <= INT_MAX.
14708 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14710 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14711 (SAFE_NALLOCA): New macro.
14713 * region-cache.c (struct boundary.pos, find_cache_boundary)
14714 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14715 (set_cache_region, invalidate_region_cache)
14716 (revalidate_region_cache, know_region_cache, region_cache_forward)
14717 (region_cache_backward, pp_cache):
14718 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14719 so that ptrdiff_t * can be passed to xpalloc.
14720 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14721 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14722 (pp_cache): Don't assume cache_len fits in int.
14723 * region-cache.h: Adjust extern decls to match.
14725 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14726 EMACS_INT, since either will do, for xpalloc.

14739 because xmalloc/xrealloc may not return.
14740 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14741 now that we have proper integer overflow checking.
14742 (record_overlay_string, overlay_strings): Catch overflows when
14743 calculating size of overlay_str_buf.
14745 * callproc.c (Fcall_process): Check for size overflow when
14746 calculating size of args2.

14749 require adding more-complicated checks.
14751 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14752 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

14792 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14794 * emacs.c (main): Do not reallocate argv, since there is a null at
14795 the end that can be overwritten, and this way there's no need to
14796 worry about size-calculation overflow.
14797 (sort_args): Check for size-calculation overflow.
14799 * eval.c (init_eval_once, grow_specpdl): Don't update size until

14805 Check for integer overflow.
14806 (x_set_alpha): Do not assume XINT fits in int.
14808 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14809 This is for the members text_lines, text_cols, total_lines, total_cols,
14810 where the system imposes an 'int' limit.
14812 * fringe.c (Fdefine_fringe_bitmap):
14813 Don't update size until alloc works.

14818 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14819 Check for size-calculation overflow.
14820 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14821 do, as we prefer signed integers.
14822 (id_to_widget.max_size, id_to_widget.used)
14823 (xg_store_widget_in_map, xg_remove_widget_from_map)

14828 * gtkutil.h: Change prototypes to match the above.
14830 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

14877 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14878 for command line length. Do not attempt to address one before the
14879 beginning of an array, as that's not portable.

14914 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14915 sizes, since they can exceed INT_MAX in size. Check for size

14925 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14926 (X_LONG_MIN): New macros.
14927 Use them to make the following changes clearer.
14928 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14929 This change doesn't affect the value now, but it may help remind
14930 future maintainers not to raise the value too much later.
14931 (SELECTION_QUANTUM): Remove, replacing with ...
14932 (selection_quantum): ... new function, which avoids overflow.
14934 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14935 assumption that selection length fits in 'int'.

14952 Don't store size until memory allocation succeeds.
14953 (x_get_window_property): Plug memory leak on memory exhaustion.
14954 Don't double-block input; malloc is safe here. Don't assume 2**34
14955 - 4 fits in unsigned long. Add an xassert to check
14956 XGetWindowProperty overflow. Be more careful about overflow
14957 calculations, and distinguish size from memory overflow better.
14958 (receive_incremental_selection): When tracing, don't assume
14959 unsigned int is less than INT_MAX.
14960 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

14963 in the range -65535 through -1 fit in an X unsigned short.
14964 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14965 result parameters unless successful. Rely on cons_to_unsigned
14966 to report problems with elements; the old code wasn't right anyway.
14967 (x_check_property_data): Check for int overflow; we cannot use
14968 a wider type due to X limits.

15001 * lisp.h (hash_lookup, hash_put):
15002 * minibuf.c (Ftest_completion):
15003 Use ptrdiff_t for hash table indexes, not int (which is too
15004 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15005 32-bit --with-wide-int hosts).
15007 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15008 Add a FIXME comment about memory leaks.

15016 with outlandish widths.
15017 * character.h (sanitize_tab_width): Rename from sanitize_width,
15018 now that we have two such functions. All uses changed.

15037 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15038 (x_send_scroll_bar_event): Likewise. Check that the size does not
15039 exceed limits imposed by XClientMessageEvent, as well as the usual
15040 ptrdiff_t and size_t limits.
15042 * keyboard.c: Overflow, signedness and related fixes.
15043 (make_lispy_movement): Use same integer type in forward decl
15044 that is used in the definition.
15045 (read_key_sequence, keyremap_step):
15046 Change bufsize argument back to int, undoing my 2011-03-30 change.
15047 We prefer signed types, and int is wide enough here.
15048 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15049 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15050 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15051 length, not size_t. Use ptrdiff_t for index, not int.
15052 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15053 possibility of integer overflow.

15081 Prefer int to unsigned where either will do.
15082 (tiff_handler): New function, combining the cores of the
15083 old tiff_error_handler and tiff_warning_handler.
15084 This function is rewritten to use vsnprintf and thereby avoid
15085 stack buffer overflows. It uses only the features of vsnprintf
15086 that are common to both POSIX and native Microsoft.
15087 (tiff_error_handler, tiff_warning_handler): Use it.
15088 (tiff_load, gif_load, imagemagick_load_image):
15089 Don't assume :index value fits in 'int'.
15090 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15091 (imagemagick_load_image): Check that crop parameters fit into
15092 the integer types that MagickCropImage accepts. Don't assume
15093 Vimagemagick_render_type has a nonnegative value. Don't assume
15094 size_t fits in 'long'.
15095 (gs_load): Use printmax_t to print the widest integers possible.

15098 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15100 * xdisp.c (redisplay_window): Don't force window start if point

15105 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
15106 the display spec is of the form `(space ...)'.
15107 (handle_display_spec): Return the value returned by
15108 handle_single_display_spec, not just 1 or zero.
15109 (handle_single_display_spec): If the display spec is of the form
15110 `(space ...)', and specifies display in the text area, return 2
15112 (try_cursor_movement): Check for the need to scroll more
15113 accurately, and prefer exact match for point under bidi.
15114 Don't advance `row' beyond the last row of the window.

15132 buffers, return left-to-right.
15133 (set_cursor_from_row): Consider candidate row a win if its glyph
15134 represents a newline and point is on that newline. Fixes cursor
15135 positioning on the newline at EOL of R2L text within L2R
15136 paragraph, and vice versa.
15137 (try_cursor_movement): Check continued rows, in addition to
15138 continuation rows. Fixes unwarranted scroll when point enters a
15139 continued line of R2L text within an L2R paragraph, or vice versa.
15140 (cursor_row_p): Consider the case of point being equal to
15141 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15142 from the end of a short line to the beginning of a continued line
15143 of R2L text within L2R paragraph.
15144 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

15160 2011-08-22 Kenichi Handa <handa@m17n.org>
15162 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
15163 extra slot even if the purpose is char-code-property-table.
15165 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15167 * xdisp.c (redisplay_window): When computing centering_position,
15168 account for the height of the header line. (Bug#8874)
15170 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15171 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15172 candidate is selected by the mouse, and that candidate has a
15173 composed character under the mouse.
15175 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15176 coordinates reported by pos-visible-in-window-p for a composed
15177 character in column zero.
15179 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

15183 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15185 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15186 consider it a hit if to_charpos is anywhere in the range of the
15187 composed buffer positions.
15189 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15191 * image.c (gif_load): Don't assume that each subimage has the same
15192 dimensions as the base image. Handle disposal method that is
15193 "undefined" by the gif spec (Bug#9335).
15195 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15197 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15202 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15203 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15204 from an Org mode buffer to a Speedbar frame.
15206 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15207 a composition, take its buffer position from IT->cmp_it.charpos.
15208 Fixes cursor positioning at the beginning of a line that begins
15209 with a composed character.
15211 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15213 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15214 character bidirectional type, use STRONG_L instead. Fixes crashes
15215 in a buffer produced by `describe-categories'.
15217 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15218 members before the level stack, so they would be saved and
15219 restored when copying iterator state. Fixes incorrect reordering
15220 around TABs covered by display properties.
15222 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15224 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15229 (internal_condition_case_2, internal_condition_case_n):
15230 Remove unnecessary aborts (Bug#9081).
15232 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15234 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15235 has no `load' handler, try opening the file locally. (Bug#9311)
15237 2011-08-16 Ken Brown <kbrown@cornell.edu>
15239 * gmalloc.c: Expand comment.
15241 2011-08-16 Eli Zaretskii <eliz@gnu.org>

15255 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
15257 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
15258 in the static heap.
15259 [CYGWIN] (special_realloc): New function.
15260 (_realloc_internal_nolock) [CYGWIN]: Use the new function on

15292 2011-08-14 Eli Zaretskii <eliz@gnu.org>
15294 * xdisp.c (move_it_in_display_line_to): Don't invoke
15295 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15296 ppos_it. Fixes vertical cursor motion when line beginning is
15297 covered by an image. (Bug#9296)
15299 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15301 * nsterm.h (ns_run_ascript): Declare.

15305 (ns_run_ascript): New function.
15306 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15307 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15308 the event loop. Get status from as_status (Bug#7276).
15310 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15311 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15312 the event loop (Bug#7276).
15314 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
15316 * gnutls.c (QCgnutls_bootprop_priority)

15318 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
15319 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
15320 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
15321 (QCgnutls_bootprop_verify_hostname_error)
15322 (QCgnutls_bootprop_callbacks_verify): Rename from
15323 Qgnutls_bootprop_..., all uses changed.

15337 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
15338 (Fnetwork_interface_list): Allocate in increments of bytes instead
15339 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15340 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15342 (struct ifflag_def): notrailers is smart on OSX.
15343 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15344 Get hardware address with getifaddrs if available.
15346 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15348 * xdisp.c (iterate_out_of_display_property): xassert that
15349 IT->position is set to within IT->object's boundaries. Break from
15350 the loop as soon as EOB is reached; avoids infloops in redisplay
15351 when IT->position is set up wrongly due to some bug.
15352 Set IT->current to match the bidi iterator unconditionally.
15353 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15354 entry. Force push_it to save on the stack the current
15355 buffer/string position, to be restored by pop_it. Fix flags in
15356 the iterator structure wrt the object coming from a display
15357 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15358 properties. (Bug#9284)
15360 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15362 * fontset.c (fontset_get_font_group): Add proper type checks.

15375 no-display-properties-and-no-overlays under bidi display.
15376 Set disp_pos in the bidi iterator to avoid searches for display
15377 properties and overlays.
15379 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
15381 * editfns.c (Fset_time_zone_rule): Document relationship with the

15390 restore_point_unwind (Bug#5984).
15392 2011-08-07 Juri Linkov <juri@jurta.org>
15394 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15395 to show the arg `TIME' instead of `TIMEVAL'.
15397 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15399 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15400 display property strides EOL and includes a newline, as in
15401 longlines-mode. (Bug#9254)
15402 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15403 word-wrap under bidirectional display. (Bug#9224)
15405 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15406 is non-zero, even if the data buffer is NULL. Fixes a crash in
15407 vertical-motion with longlines-mode. (Bug#9254)
15409 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15411 * bidi.c <bidi_cache_total_alloc>: Now static.
15412 (bidi_initialize): Initialize bidi_cache_total_alloc.
15414 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15417 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15418 amount allocated this far in `bidi_cache_total_alloc'.
15419 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15420 non-zero, only free the data buffer without restoring the cache
15421 contents. All callers changed.
15423 * dispextern.h (bidi_unshelve_cache): Update prototype.
15425 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15426 (move_it_in_display_line, move_it_to)
15427 (move_it_vertically_backward, move_it_by_lines): Replace the call
15428 to xfree to an equivalent call to bidi_unshelve_cache.
15429 (move_it_in_display_line_to): Fix logic of returning
15430 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
15432 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15434 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
15435 came from a string character with a `cursor' property. (Bug#9229)
15437 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15439 * Makefile.in (LIB_PTHREAD): New variable.
15440 (LIBES): Add LIB_PTHREAD (Bug#9216).
15442 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
15443 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
15445 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
15447 * regex.c (re_iswctype): Remove some redundant boolean conversions.
15449 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
15451 * xterm.c (x_find_topmost_parent): New function.
15452 (x_set_frame_alpha): Find topmost parent window with
15453 x_find_topmost_parent and set the property there also (bug#9181).
15454 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
15456 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
15458 * callproc.c (Fcall_process): Avoid vfork clobbering
15459 the local vars buffer, coding_systems, current_dir.

15482 for a display string or property. If found, set DISP_PROP_P
15485 * bidi.c (bidi_fetch_char): Accept an additional argument
15486 DISP_PROP_P, and pass it to compute_display_string_pos.
15487 Only handle text covered by a display string if DISP_PROP_P is returned
15488 non-zero. All callers of bidi_fetch_char changed.
15490 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15492 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.

15497 last character M-[char] is translated to ESC [char] (bug#7541).
15499 2011-08-02 Kenichi Handa <handa@m17n.org>
15501 * lisp.h (uniprop_table): Extern it.
15503 * chartab.c (uniprop_table): Make it non-static.
15505 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15507 * xdisp.c (forward_to_next_line_start): Accept additional argument
15508 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15510 (reseat_at_next_visible_line_start): Use the bidi iterator state
15511 returned by forward_to_next_line_start to restore the state of
15512 it->bidi_it after backing up to previous newline. (Bug#9212)
15514 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15516 * regex.c (re_comp): Protoize.
15517 (re_exec): Fix return type.
15518 (regexec): Fix type of `ret'. (Bug#9203)
15520 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15522 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15523 This is needed if max-image-size is a floating-point number.
15525 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15527 * print.c (print_object): Print empty symbol as ##.

15538 contents (Bug#9176).
15539 (EmacsTooltip -init): Remove bezels and add shadows to
15542 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15543 or scroll bar (Bug#8470).
15545 * nsfont.m (nsfont_open): Remove assignment to voffset and

15549 * nsterm.h (nsfont_info): Remove voffset field.
15551 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15553 Implement strike-through and overline on NextStep (Bug#8863).
15555 * nsfont.m (nsfont_open): Use underline position provided by font,
15556 instead of hard-coded value of 2.

15572 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15574 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15575 Without this fix, if a signal arrives just after memory fills up,
15576 'malloc' might be invoked reentrantly.
15578 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15579 In other words, assume that every image size is allowed, on non-X
15580 hosts. This assumption is probably wrong, but it lets Emacs compile.
15582 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15584 * regex.c (re_iswctype): Convert return values to boolean.

15588 * xdisp.c (compute_display_string_pos): Don't use cached display
15589 string position if the buffer had its restriction changed.
15592 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15594 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15596 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15598 Integer signedness and overflow and related fixes. (Bug#9079)
15600 * bidi.c: Integer size and overflow fixes.
15601 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15602 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15603 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15604 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15605 (bidi_find_other_level_edge):
15606 Use ptrdiff_t instead of EMACS_INT where either will do.
15607 This works better on 32-bit hosts configured --with-wide-int.
15608 (bidi_cache_ensure_space): Check for size-calculation overflow.
15609 Use % rather than repeated addition, for better worst-case speed.
15610 Don't set bidi_cache_size until after xrealloc returns, because it
15612 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15613 (bidi_cache_ensure_space): Also check that the bidi cache size
15614 does not exceed that of the largest Lisp string or buffer. See Eli
15615 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15617 * alloc.c (__malloc_size_t): Remove.
15618 All uses replaced by size_t. See Andreas Schwab's note
15619 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15621 * image.c: Improve checking for integer overflow.
15622 (check_image_size): Assume that f is nonnull, since
15623 it is always nonnull in practice. This is one less thing to
15624 worry about when checking for integer overflow later.
15625 (x_check_image_size): New function, which checks for integer
15626 overflow issues inside X.
15627 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15628 This removes the need for a memory_full check.
15629 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15630 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15631 (xbm_read_bitmap_data): Change locals back to 'int', since
15632 their values must fit in 'int'.
15633 (xpm_load_image, png_load, tiff_load):
15634 Invoke x_create_x_image_and_pixmap earlier,
15635 to avoid much needless work if the image is too large.
15636 (tiff_load): Treat overly large images as if
15637 x_create_x_image_and_pixmap failed, not as malloc failures.
15638 (gs_load): Use x_check_image_size.
15640 * gtkutil.c: Omit integer casts.
15641 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15642 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15644 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15646 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15647 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15648 would wrongly return t on a 64-bit host.
15650 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15651 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15652 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15653 and therefore cause GCC to emit a bogus diagnostic in some cases.
15655 * image.c: Integer signedness and overflow and related fixes.
15656 This is not an exhaustive set of fixes, but it's time to
15657 record what I've got.
15658 (lookup_pixel_color, check_image_size): Remove redundant decls.
15659 (check_image_size): Don't assume that arbitrary EMACS_INT values
15660 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15661 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15662 (tiff_load, imagemagick_load_image):
15663 Check for overflow in size calculations.
15664 (x_create_x_image_and_pixmap): Remove unnecessary test for
15665 xmalloc returning NULL; that can't happen.
15666 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15667 (xpm_color_bucket): Use better integer hashing function.
15668 (xpm_cache_color): Don't possibly over-allocate memory.
15669 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15670 (gif_memory_source):
15671 Use ptrdiff_t, not int or size_t, to record sizes.
15672 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15673 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15674 either works, as we prefer signed integers.
15675 (tiff_read_from_memory, tiff_write_from_memory):
15676 Return tsize_t, not size_t, since that's what the TIFF API wants.
15677 (tiff_read_from_memory): Don't fail simply because the read would
15678 go past EOF; instead, return a short read.
15679 (tiff_load): Omit no-longer-needed casts.
15680 (Fimagemagick_types): Don't assume size fits into 'int'.
15682 Improve hashing quality when configured --with-wide-int.
15683 * fns.c (hash_string): New function, taken from sxhash_string.
15684 Do not discard information about ASCII character case; this
15685 discarding is no longer needed.
15686 (sxhash-string): Use it. Change sig to match it. Caller changed.
15687 * lisp.h: Declare it.
15688 * lread.c (hash_string): Remove, since we now use fns.c's version.
15689 The fns.c version returns a wider integer if --with-wide-int is
15690 specified, so this should help the quality of the hashing a bit.
15692 * emacs.c: Integer overflow minor fix.
15693 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15694 Define only if GNU_LINUX.
15695 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15697 * dispnew.c: Integer signedness and overflow fixes.
15698 Remove unnecessary forward decls, that were a maintenance hassle.
15699 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15701 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15702 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15703 (prepare_desired_row, line_draw_cost):
15704 Use int, not unsigned, where either works.
15705 (save_current_matrix, restore_current_matrix):
15706 Use ptrdiff_t, not size_t, where either works.
15707 (init_display): Check for overflow more accurately, and without
15708 relying on undefined behavior.
15710 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15711 Remove, replacing with the new symbols in lisp.h. All uses changed.
15712 * fileio.c (make_temp_name):
15713 * filelock.c (lock_file_1, lock_file):
15714 * xdisp.c (message_dolog):
15715 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15716 Use pMd etc. instead.
15717 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15718 replacing the pWIDE etc. symbols removed from editfns.c.
15720 * keyboard.h (num_input_events): Now uintmax_t.
15721 This is (very slightly) less likely to mess up due to wraparound.
15724 * buffer.c: Integer signedness fixes.
15725 (alloc_buffer_text, enlarge_buffer_text):
15726 Use ptrdiff_t rather than size_t when either will do, as we prefer
15729 * alloc.c: Integer signedness and overflow fixes.
15730 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15731 (__malloc_size_t): Default to size_t, not to int.
15732 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15733 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15734 Prefer ptrdiff_t to size_t when either would do, as we prefer
15736 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15737 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15738 Now const. Initialize with values that are in range even if char
15740 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15741 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15742 These functions do the right thing with sizes > 2**32.
15743 (check_depth): Now ptrdiff_t, not int.
15744 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15745 Adjust to new way of storing sizes. Check for size overflow bugs
15747 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15748 slightly wrong anyway, as it missed one instance of
15749 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15750 (refill_memory_reserve): Omit needless cast to size_t.
15751 (mark_object_loop_halt): Mark as externally visible.
15753 * xselect.c: Integer signedness and overflow fixes.
15754 (Fx_register_dnd_atom, x_handle_dnd_message):
15755 Use ptrdiff_t, not size_t, since we prefer signed.
15756 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15757 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15758 x_dnd_atoms_size and x_dnd_atoms_length.
15760 * doprnt.c: Prefer signed to unsigned when either works.
15762 * doprnt.c (doprnt):
15764 * xdisp.c (vmessage):
15765 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15766 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15767 prefer signed arithmetic to avoid comparison confusion.
15768 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15769 but is a bit tricky.
15771 Assume freestanding C89 headers, string.h, stdlib.h.
15772 * data.c, doprnt.c, floatfns.c, print.c:
15773 Include float.h unconditionally.
15774 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15775 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15776 * regex.c: Likewise for stddef.h, string.h.
15777 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15778 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15779 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15780 (STDC_HEADERS): Remove obsolete defines.
15781 * sysdep.c: Include limits.h unconditionally.
15783 Assume support for memcmp, memcpy, memmove, memset.
15784 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15785 * regex.c (memcmp, memcpy):
15786 Remove; we assume C89 now.
15788 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15789 (__malloc_safe_bcopy): Remove; no longer needed.
15791 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15792 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15793 well either way, and we prefer signed to unsigned.
15795 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15797 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15798 closes the connection while we're reading (bug#9182).
15800 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15802 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15803 are specified (Bug#9168).
15805 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15807 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15808 Found by GCC static checking and --with-wide-int on a 32-bit host.
15810 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15812 * xdisp.c (compute_display_string_pos): Fix logic of caching
15813 previous display string position. Initialize cached_prev_pos to
15814 -1. Fixes slow-down at the beginning of a buffer.
15816 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15818 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15819 for attrs[LFACE_FONTSET_INDEX].
15821 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15823 * xml.c (parse_region): Remove unused local
15824 that was recently introduced.
15826 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15828 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15829 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15831 * xdisp.c (move_it_in_display_line_to): Record the best matching
15832 position for TO_CHARPOS while scanning the line, and restore it on
15833 exit if none of the characters scanned was an exact match.
15834 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15835 when exact match is impossible due to invisible text, and the
15836 lines are truncated.
15838 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15840 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15843 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15845 Fix a significant slow-down of cursor motion with C-n, C-p,
15846 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15847 auto-repeat under bidi redisplay in fontified buffers.
15848 * xdisp.c (compute_stop_pos_backwards): New function.
15849 (next_element_from_buffer): Call compute_stop_pos_backwards to
15850 find a suitable prev_stop when we find ourselves before
15852 (reseat): Don't look for prev_stop, as that could mean a very long
15854 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15855 <cached_disp_overlay_modiff>: Cache for last found display string
15857 (compute_display_string_pos): Return the cached position if asked
15858 about the same buffer in the same area of character positions, and
15859 the buffer wasn't changed since the time the display string
15860 position was cached.
15862 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15864 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15865 is an integer, which is important for empty lines. (Bug#9149)
15867 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15869 * frame.c (Fmodify_frame_parameters): In tty case, update the
15870 default face if necessary (Bug#4238).
15872 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15874 * editfns.c (Fstring_to_char): No need to explain what a character
15875 is in the docstring (Bug#6576).
15877 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15879 * xml.c (parse_region): Make sure we always return a tree.
15881 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15883 * xml.c (parse_region): If a document contains only comments,
15886 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15888 * xml.c (make_dom): Return comments, too.
15890 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15893 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15894 and the surrounding thread.
15895 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15896 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15897 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15899 * s/openbsd.h (BROKEN_SIGIO): Define.
15900 * unexelf.c (unexec) [__OpenBSD__]:
15901 Don't update the .mdebug section of the Alpha COFF symbol table.
15903 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15905 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15908 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15910 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15911 This fixes some race conditions on the permissions of any newly
15914 * alloc.c (valid_pointer_p): Use pipe, not open.
15915 This fixes some permissions issues when debugging.
15917 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15918 If fchown fails to set both uid and gid, try to set just gid,
15919 as that is sometimes allowed. Adjust the file's mode to eliminate
15920 setuid or setgid bits that are inappropriate if fchown fails.
15922 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15924 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15925 to compare Lisp_Objects.
15926 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15927 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15928 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15930 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15932 * lread.c (read_integer): Unread even EOF character.
15933 (read1): Likewise. Properly record start position of symbol.
15935 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15936 symbol character follows.
15938 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15940 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15941 This works around a problem with the previous change to Fcopy_file.
15942 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15943 and without this change, GCC might complain about discarding
15944 fchown's return value.
15946 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15948 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15950 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15952 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15954 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15956 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15957 it's used from the C level.
15959 * process.c: Use the same condition for POLL_FOR_INPUT in both
15960 keyboard.c and process.c (bug#1858).
15962 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15964 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15965 (Fgnutls_boot): Use it.
15967 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15969 * doc.c (Fsubstitute_command_keys): Revert last change.
15971 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15973 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15974 quotes the next character, and doesn't affect other longer
15975 sequences (bug#8935).
15977 * lread.c (syms_of_lread): Clarify that is isn't only
15978 `eval-buffer' and `eval-defun' that's affected by
15979 `lexical-binding' (bug#8460).
15981 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15983 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15984 bidi redisplay when a line includes both an image and is truncated.
15986 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15988 Fix minor problems found by static checking.
15989 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15990 (elsz): Now a signed constant, not a size_t var. We prefer signed
15991 types to unsigned, to avoid integer comparison confusion. Without
15992 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15993 "cannot optimize loop, the loop counter may overflow", a symptom
15995 * indent.c (Fvertical_motion): Mark locals as initialized.
15996 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15998 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16000 * search.c (Fre_search_backward): Mention `case-fold-search' in
16001 all the re_search_* functions (bug#8138).
16003 * keyboard.c (Fopen_dribble_file): Document when the file is
16006 2011-07-14 Eli Zaretskii <eliz@gnu.org>
16008 * bidi.c (bidi_dump_cached_states): Fix format of displaying
16011 Support bidi reordering of display and overlay strings.
16012 * xdisp.c (compute_display_string_pos)
16013 (compute_display_string_end): Accept additional argument STRING.
16014 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
16015 (reseat_to_string): Initialize bidi_it->string.s and
16016 bidi_it->string.schars.
16017 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
16018 NULL (avoids a crash in bidi_paragraph_init).
16019 Initialize itb.string.lstring.
16020 (init_iterator): Call bidi_init_it only of a valid
16021 buffer position was specified. Initialize paragraph_embedding to
16023 (reseat_to_string): Initialize the bidi iterator.
16024 (display_string): If we need to ignore text properties of
16025 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16026 original value of -1 will not work with bidi.)
16027 (compute_display_string_pos): First arg is now struct
16028 `text_pos *'; all callers changed. Support display properties on
16030 (compute_display_string_end): Support display properties on Lisp
16032 (init_iterator, reseat_1, reseat_to_string): Initialize the
16033 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16034 when iterating on a string not from display properties).
16035 (compute_display_string_pos, compute_display_string_end):
16036 Fix calculation of the object to scan. Fixes an error when using
16038 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16039 base_level_stop; instead, set base_level_stop to BEGV.
16040 Fixes crashes in vertical-motion.
16041 (next_element_from_buffer): Improve commentary for when
16042 the iterator is before prev_stop.
16043 (init_iterator): Initialize bidi_p from the default value of
16044 bidi-display-reordering, not from buffer-local value. Use the
16045 buffer-local value only if initializing for buffer iteration.
16046 (handle_invisible_prop): Support invisible properties on strings
16047 that are being bidi-reordered.
16048 (set_iterator_to_next): Support bidi reordering of C strings and
16050 (next_element_from_string): Support bidi reordering of Lisp
16052 (handle_stop_backwards): Support Lisp strings as well.
16053 (display_string): Support display of R2L glyph rows.
16054 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16055 (init_iterator): Don't initialize it->bidi_p for strings
16057 (reseat_to_string): Initialize it->bidi_p for strings here.
16058 (next_element_from_string, next_element_from_c_string)
16059 (next_element_from_buffer): Add xassert's for correspondence
16060 between IT's object being iterated and it->bidi_it.string
16062 (face_before_or_after_it_pos): Support bidi iteration.
16063 (next_element_from_c_string): Handle the case of the first string
16064 character that is not the first one in the visual order.
16065 (get_visually_first_element): New function, refactored from common
16066 parts of next_element_from_buffer, next_element_from_string, and
16067 next_element_from_c_string.

16518 * alloc.c (mark_buffer):
16519 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
16520 (clone_per_buffer_values): Don't assume that
16521 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
16522 This isn't true in general, and it's particularly not true
16523 if Emacs is configured with --with-wide-int.
16524 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16525 New macros, used in the buffer.c change.

16559 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
16561 Random fixes. E.g., (random) never returned negative values.
16562 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16563 subseconds part to the entropy, as that's a bit more random.
16564 Prefer signed to unsigned, since the signedness doesn't matter and
16565 in general we prefer signed. When given a limit, use a
16566 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16567 latter isn't right if USE_2_TAGS_FOR_INTS.
16568 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16569 not 0..VALMASK. Don't discard "excess" bits that random () returns.
16571 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
16573 * textprop.c (text_property_stickiness):
16574 Obey Vtext_property_default_nonsticky.

16581 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16582 This is more efficient than Ffile_directory_p and avoids a minor race.
16584 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16586 * buffer.c (Foverlay_put): Say what the return value is
16589 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16590 is a directory before asking whether to use the file name
16592 (barf_or_query_if_file_exists): Make the "File is a directory"
16593 error be more correct.
16595 * fns.c (Frequire): Remove the mention of the .gz files, since
16596 that's installation-specific, but keep the mention of
16597 `get-load-suffixes'.

16609 Qgnutls_bootprop_verify_error (which is no longer used).
16611 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16612 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16613 Also (re)move comments that are misplaced or no longer relevant.
16615 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16617 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

16676 (syms_of_keymap): Defsubr make-composed-keymap.
16677 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

16714 * eval.c (struct backtrace): Simplify and port the data structure.
16715 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16716 signed bit field, as this assumption is not portable and it makes
16717 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16718 "char debug_on_exit : 1" as this is not portable either; instead,
16719 use the portable "unsigned int debug_on_exit : 1". Remove unused
16720 member evalargs. Remove obsolete comments about cc bombing out.
16722 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16946 * xterm.c (x_check_font): Remove unused local.
16947 * scroll.c (CHECK_BOUNDS):
16948 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16949 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16950 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16951 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16952 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16954 (debug_method_add): Use va_list and vsprintf rather than relying
16955 on undefined behavior with wrong number of arguments.
16956 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16957 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16958 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16959 since we're not interested in debugging glyphs with old libraries.
16960 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16961 GCC 4.6.0's static checking.
16963 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16965 Integer overflow and signedness fixes (Bug#8873).
16966 A few related buffer overrun fixes, too.
16968 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
16970 * dispextern.h (struct face.stipple):
16971 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)

16973 (x_create_bitmap_from_data, x_create_bitmap_from_file)
16974 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
16975 (x_create_bitmap_from_xpm_data):
16976 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16977 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16979 * xfaces.c (load_pixmap):
16980 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16981 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16982 (.bitmaps_last, struct x_output.icon_bitmap):
16983 Use ptrdiff_t, not int, for bitmap indexes.
16984 (x_allocate_bitmap_record): Check for size overflow.
16985 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16987 Use ptrdiff_t, not int, for overlay counts.
16988 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16989 * editfns.c (overlays_around, get_pos_property):
16990 * textprop.c (get_char_property_and_overlay):
16991 * xdisp.c (next_overlay_change, note_mouse_highlight):
16992 * xfaces.c (face_at_buffer_position):
16993 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16994 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16995 (Fnext_overlay_change, Fprevious_overlay_change)
16996 (mouse_face_overlay_overlaps, Foverlays_in):
16997 Use ptrdiff_t, not int, for sizes.
16998 (overlays_at, overlays_in): Check for size-calculation overflow.
17000 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17002 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17003 (x_session_initialize): Do not assume string length fits in int.
17005 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17006 This is unlikely, but can occur if DPI is outlandish.
17008 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17009 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17011 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17012 * xrdb.c (magic_file_p, search_magic_path):
17013 Omit last arg SUFFIX; it was always 0. All callers changed.
17014 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17016 * xfont.c (xfont_match): Avoid need for strlen.
17018 * xfns.c: Don't assume strlen fits in int.
17019 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17021 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17022 not unsigned long, as we prefer signed integers. All callers changed.
17023 Detect integer overflow in repeat count.
17024 (message_dolog): Don't assume print length fits in 39 bytes.
17025 (display_mode_element): Don't assume strlen fits in int.
17027 * termcap.c: Don't assume sizes fit in int and never overflow.
17028 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17029 (gobble_line): Check for size-calculation overflow.
17031 * minibuf.c (Fread_buffer):
17032 * lread.c (intern, intern_c_string):
17033 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17034 Don't assume string length fits in int.
17036 * keyboard.c (parse_tool_bar_item):
17037 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17039 * font.c: Don't assume string length fits in int.
17040 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17041 Use ptrdiff_t, not int.
17042 (font_intern_prop): Don't assume string length fits in int.
17043 Don't assume integer property fits in fixnum.
17044 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17046 * filelock.c: Fix some buffer overrun and integer overflow issues.
17047 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17048 Reformulate so as not to need the command string.
17049 Invoke gzip -cd rather than gunzip, as it's more portable.
17050 (lock_info_type, lock_file_1, lock_file):
17051 Don't assume pid_t and time_t fit in unsigned long.
17052 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17053 (current_lock_owner): Prefer signed type for sizes.
17054 Use memcpy, not strncpy, where memcpy is what is really wanted.
17055 Don't assume (via atoi) that time_t and pid_t fit in int.
17056 Check for time_t and/or pid_t out of range, e.g., via a network share.
17057 Don't alloca where an auto var works fine.
17059 * fileio.c: Fix some integer overflow issues.
17060 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17061 Don't assume string length fits in int.
17062 (directory_file_name): Don't assume string length fits in long.
17063 (make_temp_name): Don't assume pid fits in int, or that its print
17064 length is less than 20.
17066 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17068 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17070 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17072 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17073 We prefer signed integers, even for size calculations.
17075 * emacs.c: Don't assume string length fits in 'int'.
17076 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17077 (main): Don't invoke strlen when not needed.
17079 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17080 (XD_DEBUG_MESSAGE): Don't waste a byte.
17082 * callproc.c (getenv_internal_1, getenv_internal)
17083 (Fgetenv_internal):
17084 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17086 * lread.c (invalid_syntax): Omit length argument.
17087 All uses changed. This doesn't fix a bug, but it simplifies the
17088 code away from its former Hollerith-constant appearance, and it's
17089 one less 'int' to worry about when looking at integer-overflow issues.
17090 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17092 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17093 This didn't break anything, but it didn't help either.
17094 It's confusing to put a bogus integer in a place where the actual
17095 value does not matter.
17096 (LIST_END_P): Remove unused macro and its bogus comment.
17097 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17099 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17100 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17102 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17103 We prefer signed types, and the value cannot exceed the EMACS_INT
17104 range anyway (because otherwise the length would not be representable).
17105 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17106 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17107 This avoids a GCC warning when WIDE_EMACS_INT.
17109 * indent.c (sane_tab_width): New function.
17110 (current_column, scan_for_column, Findent_to, position_indentation)
17111 (compute_motion): Use it. This is just for clarity.
17112 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17114 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17116 * lisp.h (lint_assume): New macro.
17117 * composite.c (composition_gstring_put_cache):
17118 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17120 * editfns.c, insdel.c:
17121 Omit unnecessary forward decls, to simplify future changes.
17123 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17125 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17127 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17128 Use much-faster test for byte-length change.
17129 Don't assume string byte-length fits in 'int'.
17130 Check that character arg fits in 'int'.
17131 (mapcar1): Declare byte as byte, for clarity.
17133 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17135 * fns.c (concat): Catch string overflow earlier.
17136 Do not rely on integer wraparound.
17138 * dispextern.h (struct it.overlay_strings_charpos)
17139 (struct it.selective): Now EMACS_INT, not int.
17140 * xdisp.c (forward_to_next_line_start)
17141 (back_to_previous_visible_line_start)
17142 (reseat_at_next_visible_line_start, next_element_from_buffer):
17143 Don't arbitrarily truncate the value of 'selective' to int.
17145 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17147 * composite.c: Don't truncate sizes to 'int'.
17148 (composition_gstring_p, composition_reseat_it)
17149 (composition_adjust_point): Use EMACS_INT, not int.
17150 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17151 not EMACS_UINT, for indexes.
17153 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17155 * buffer.c: Include <verify.h>.
17156 (struct sortvec.priority, struct sortstr.priority):
17157 Now EMACS_INT, not int.
17158 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17159 (struct sortstr.size, record_overlay_string)
17160 (struct sortstrlist.size, struct sortlist.used):
17161 Don't truncate size to int.
17162 (record_overlay_string): Check for size-calculation overflow.
17163 (init_buffer_once): Check at compile-time, not run-time.
17165 2011-06-22 Jim Meyering <meyering@redhat.com>
17167 Don't leak an XBM-image-sized buffer
17168 * image.c (xbm_load): Free the image buffer after using it.
17170 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17173 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17174 that Sun C diagnosed.
17175 * fns.c (secure_hash): Fix pointer signedness issue.
17176 * intervals.c (static_offset_intervals): New function.
17177 (offset_intervals): Use it.
17179 2011-06-21 Leo Liu <sdl.web@gmail.com>
17182 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17185 * fns.c (secure_hash): Rename from crypto_hash_function and change
17186 the first arg to accept symbols.
17187 (Fsecure_hash): New primitive.
17188 (syms_of_fns): New symbols.
17190 2011-06-20 Deniz Dogan <deniz@dogan.se>
17192 * process.c (Fset_process_buffer): Clarify return value in
17195 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17197 * dispnew.c (add_window_display_history): Use BVAR.
17199 * xdisp.c (debug_method_add): Use BVAR.
17200 (check_window_end, dump_glyph_matrix, dump_glyph)
17201 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17203 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17206 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17207 check till after the cache is created in init_frame_faces.
17209 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17211 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17213 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17215 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17216 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17217 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17219 Improve buffer-overflow checking (Bug#8873).
17220 * fileio.c (Finsert_file_contents):
17221 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17222 Remove the old (too-loose) buffer overflow checks.
17223 They weren't needed, since make_gap checks for buffer overflow.
17224 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17225 The old code merely checked for Emacs fixnum overflow, and relied
17226 on undefined (wraparound) behavior. The new code avoids undefined
17227 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17229 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17230 Tune. Don't use wider integers than needed. Don't use alloca.
17231 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17233 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17235 * insdel.c, lisp.h (buffer_overflow): New function.
17236 (insert_from_buffer_1, replace_range, replace_range_2):
17237 * insdel.c (make_gap_larger):
17238 * editfns.c (Finsert_char):
17239 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17241 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17243 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17245 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17247 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17248 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17250 * fileio.c: Don't assume EMACS_INT fits in off_t.
17251 (emacs_lseek): New static function.
17252 (Finsert_file_contents, Fwrite_region): Use it.
17253 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17255 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17257 * fns.c: Don't overflow int when computing a list length.
17258 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17259 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17260 truncation on 64-bit hosts. Check for QUIT every
17261 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17262 faster and is responsive enough.
17263 (Flength): Report an error instead of overflowing an integer.
17264 (Fsafe_length): Return a float if the value is not representable
17265 as a fixnum. This shouldn't happen except in contrived situations.
17266 (Fnthcdr, Fsort): Don't assume list length fits in int.
17267 (Fcopy_sequence): Don't assume vector length fits in int.
17269 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17270 (header_size, word_size): New constants.
17271 (allocate_vectorlike): Don't check size overflow here.
17272 (allocate_vector): Check it here instead, since this is the only
17273 caller of allocate_vectorlike that could cause overflow.
17274 Check that the new vector's length is representable as a fixnum.
17276 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17277 The previous code was bogus. For example, next_almost_prime (32)
17278 returned 39, which is undesirable as it is a multiple of 3; and
17279 next_almost_prime (24) returned 25, which is a multiple of 5 so
17280 why was the code bothering to check for multiples of 7?
17282 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17284 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17286 Variadic C functions now count arguments with ptrdiff_t.
17287 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17288 Back then I didn't know that the Emacs coding style prefers signed int.
17289 Also, in the meantime I found a few more instances where arguments
17290 were being counted with int, which may truncate counts on 64-bit
17291 machines, or EMACS_INT, which may be unnecessarily wide.
17292 * lisp.h (struct Lisp_Subr.function.aMANY)
17293 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17294 Arg counts are now ptrdiff_t, not size_t.
17295 All variadic functions and their callers changed accordingly.
17296 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17297 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17298 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17299 * callint.c (Fcall_interactively): Check arg count for overflow,
17300 to avoid potential buffer overrun. Use signed char, not 'int',
17301 for 'varies' array, so that we needn't bother to check its size
17302 calculation for overflow.
17303 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17304 * eval.c (apply_lambda):
17305 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17306 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17307 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17309 * callint.c (Fcall_interactively): Don't use index var as event count.
17311 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17312 * mem-limits.h (SIZE): Remove; no longer used.
17314 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17316 Remove unnecessary casts.
17317 * xterm.c (x_term_init):
17318 * xfns.c (x_set_border_pixel):
17319 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17320 These aren't needed now that we assume ANSI C.
17322 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17323 It's more likely to cause problems (due to unsigned overflow)
17326 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17328 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17330 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17332 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17334 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17336 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17338 GLYPH_CODE_FACE returns EMACS_INT, not int.
17339 * dispextern.h (merge_faces):
17340 * xfaces.c (merge_faces):
17341 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17342 Don't assume EMACS_INT fits in int.
17344 * character.h (CHAR_VALID_P): Remove unused parameter.
17345 * fontset.c, lisp.h, xdisp.c: All uses changed.
17347 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17349 * fns.c (concat): Minor tuning based on overflow analysis.
17350 This doesn't fix any bugs. Use int to hold character, instead
17351 of constantly refetching from Emacs object. Use XFASTINT, not
17352 XINT, for value known to be a character. Don't bother comparing
17353 a single byte to 0400, as it's always less.
17355 * floatfns.c (Fexpt):
17356 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17358 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17361 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17363 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17364 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17365 incorrectly succeed when S was a string, because 4294967386 was
17366 truncated before it was used.
17368 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17369 Otherwise, an out-of-range integer could cause undefined behavior
17372 * composite.c: Use int, not EMACS_INT, for characters.
17373 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17374 EMACS_INT, for values that are known to be in character range.
17375 This doesn't fix any bugs but is the usual style inside Emacs and
17376 may generate better code on 32-bit machines.
17378 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17379 This is for reasons similar to the recent CHAR_STRING fix.
17380 * charset.c (Fencode_char): Check that character arg is actually
17381 a character. Pass an int to ENCODE_CHAR.
17382 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17383 wider than 'int', as a compile-time check to prevent future regressions
17386 * character.c (char_string): Remove unnecessary casts.
17388 Make sure a 64-bit char is never passed to CHAR_STRING.
17389 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17390 by silently ignoring the top 32 bits, allowing some values
17391 that were far too large to be valid characters.
17392 * character.h: Include <verify.h>.
17393 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17394 arguments are no wider than unsigned, as a compile-time check
17395 to prevent future regressions in this area.
17397 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17398 (Fsubst_char_in_region):
17400 * xdisp.c (decode_mode_spec_coding):
17401 Adjust to CHAR_STRING's new requirement.
17402 * editfns.c (Finsert_char, Fsubst_char_in_region):
17403 * fns.c (concat): Check that character args are actually
17404 characters. Without this test, these functions did the wrong
17405 thing with wildly out-of-range values on 64-bit hosts.
17407 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17408 These casts should not be needed on 32-bit hosts, either.
17409 * keyboard.c (read_char):
17410 * lread.c (Fload): Remove casts to unsigned.
17412 * lisp.h (UNSIGNED_CMP): New macro.
17413 This fixes comparison bugs on 64-bit hosts.
17414 (ASCII_CHAR_P): Use it.
17415 * casefiddle.c (casify_object):
17416 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17417 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17418 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17419 * dispextern.h (FACE_FROM_ID):
17420 * keyboard.c (read_char): Use UNSIGNED_CMP.
17422 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17423 not to EMACS_INT, to avoid GCC warning.
17425 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17427 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17428 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17429 isn't needed on 32-bit machines.
17431 * buffer.c (Fgenerate_new_buffer_name):
17432 Use EMACS_INT for count, not int.
17433 (advance_to_char_boundary): Return EMACS_INT, not int.
17435 * data.c (Qcompiled_function): Now static.
17437 * window.c (window_body_lines): Now static.
17439 * image.c (gif_load): Rename local to avoid shadowing.
17441 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17442 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17443 * alloc.c (make_save_value): Integer argument is now of type
17444 ptrdiff_t, not int.
17445 (mark_object): Use ptrdiff_t, not int.
17446 * lisp.h (pD): New macro.
17447 * print.c (print_object): Use it.
17449 * alloc.c: Use EMACS_INT, not int, to count objects.
17450 (total_conses, total_markers, total_symbols, total_vector_size)
17451 (total_free_conses, total_free_markers, total_free_symbols)
17452 (total_free_floats, total_floats, total_free_intervals)
17453 (total_intervals, total_strings, total_free_strings):
17454 Now EMACS_INT, not int. All uses changed.
17455 (Fgarbage_collect): Compute overall total using a double, so that
17456 integer overflow is less likely to be a problem. Check for overflow
17457 when converting back to an integer.
17458 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17459 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17460 These were 'int' variables that could overflow on 64-bit hosts;
17461 they were never used, so remove them instead of repairing them.
17462 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17463 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17464 Previously, this ceilinged at INT_MAX, but that doesn't work on
17466 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17468 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17469 (allocate_vectorlike): Check for ptrdiff_t overflow.
17470 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17471 when a (possibly-narrower) signed value would do just as well.
17472 We prefer using signed arithmetic, to avoid comparison confusion.
17474 * alloc.c: Catch some string size overflows that we were missing.
17475 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17476 for convenience in STRING_BYTES_MAX.
17477 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17478 The definition here is exact; the one in lisp.h was approximate.
17479 (allocate_string_data): Check for string overflow. This catches
17480 some instances we weren't catching before. Also, it catches
17481 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17482 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17483 and ptrdiff_t and EMACS_INT are both 64 bits.
17485 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17486 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17487 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17489 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17491 * alloc.c (Fmake_string): Check for out-of-range init.
17493 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17495 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17497 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17499 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17500 xg_get_default_scrollbar_width.
17502 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17503 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17504 (style_changed_cb): Call update_theme_scrollbar_width and call
17505 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17506 all frames (Bug#8505).

17510 and height if HAVE_GTK3 (Bug#8505).
17511 (scroll_bar_width_for_theme): New variable.
17512 (update_theme_scrollbar_width): New function.
17513 (xg_get_default_scrollbar_width): Move code to
17514 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17515 (xg_initialize): Call update_theme_scrollbar_width.
17517 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17519 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

17523 * frame.c (make_frame): Call other_buffer_safely instead of
17526 * window.c (temp_output_buffer_show): Call display_buffer with
17527 second argument Vtemp_buffer_show_specifiers and reset latter
17528 immediately after the call.
17529 (Vtemp_buffer_show_specifiers): New variable.
17530 (auto_window_vscroll_p, next_screen_context_lines)
17531 (Vscroll_preserve_screen_position): Remove leading asterisks from

18076 were just reseat()'ed to a new position.
18078 * xdisp.c (set_cursor_from_row): Set start and stop points
18079 according to the row's direction when priming the loop that looks
18080 for the glyph on which to display cursor.

18082 (display_prop_intangible_p): Reimplement to call
18083 handle_display_spec instead of single_display_spec_intangible_p.

18094 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18095 value of a `display' property is a "replacing spec".
18096 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18097 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18098 the display property, but just return a value indicating whether
18099 the display property will replace the characters it covers.
18100 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18101 frame_window_p members of struct bidi_it.

18127 * gnutls.c: Use Emacs's memory allocators.
18128 Without this change, the gnutls library would invoke malloc etc.
18129 directly, which causes problems on non-SYNC_INPUT hosts, and which
18130 runs afoul of improving memory_full behavior. (Bug#8761)
18131 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18132 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18133 xfree instead of the default malloc, realloc, free.
18134 (Fgnutls_boot): No need to check for memory allocation failure,
18135 since xmalloc does that for us.

18164 need to be updated by these changes.
18165 * fns.c (make_hash_table, maybe_resize_hash_table):
18166 Check for integer overflow with large hash tables.
18167 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18168 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18169 (SXHASH_REDUCE): New macro.
18170 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18171 Use it instead of discarding useful hash info with large hash values.
18172 (sxhash_float): New function.
18173 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18174 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18175 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18176 Rewrite to use FIXNUM_BITS, as this simplifies things.
18177 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18178 Adjust signatures to match updated version of code.
18179 (consing_since_gc): Now EMACS_INT, since a single hash table can
18180 use more than INT_MAX bytes.

18229 Make it possible to run ./temacs.
18231 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18232 syms_of_callproc does the same thing. Remove test for

18250 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18252 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18254 * eval.c (Qdebug): Now static.
18255 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18256 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18257 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18259 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18261 * image.c: Various fixes to ImageMagick code comments.
18262 (Fimagemagick_types): Doc fix.
18264 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18266 Minor fixes prompted by GCC 4.6.0 warnings.
18268 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18270 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18271 (x_clipboard_manager_save_all): Move extern decl to ...
18272 * xterm.h: ... here, so that it can be checked for consistency.
18274 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18276 * xselect.c (x_clipboard_manager_save_frame)
18277 (x_clipboard_manager_save_all): New functions.
18278 (Fx_clipboard_manager_save): Lisp function deleted.
18280 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18281 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18283 * xterm.h: Update prototype.
18285 2011-05-28 William Xu <william.xwl@gmail.com>
18287 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18288 exiting (Bug#8239).
18290 2011-05-28 Jim Meyering <meyering@redhat.com>
18292 Avoid a sign-extension bug in crypto_hash_function.
18293 * fns.c (to_uchar): Define.
18294 (crypto_hash_function): Use it to convert some newly-signed
18295 variables to unsigned, to avoid sign-extension bugs. For example,
18296 without this change, (md5 "truc") would evaluate to
18297 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18298 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18299 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18301 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18303 Integer overflow fixes.
18305 * dbusbind.c: Serial number integer overflow fixes.
18306 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18307 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18308 to hold a serial number that is too large for a fixnum.
18309 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18310 Check for serial numbers out of range. Decode any serial number
18311 that was so large that it became a float. (Bug#8722)
18313 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18314 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18315 Use XFASTINT rather than XUINT when numbers are nonnegative.
18316 (xd_append_arg, Fdbus_method_return_internal):
18317 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18318 arguments, check that Lisp number is nonnegative, rather than
18319 silently wrapping negative numbers around. (Bug#8722)
18320 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18323 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18325 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18327 ccl: Add integer overflow checks.
18328 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18329 (IN_INT_RANGE): New macros.
18330 (ccl_driver): Use them to check for integer overflow when
18331 decoding a CCL program. Many of the new checks are whether XINT (x)
18332 fits in int; it doesn't always, on 64-bit hosts. The new version
18333 doesn't catch all possible integer overflows, but it's an
18334 improvement. (Bug#8719)
18336 * alloc.c (make_event_array): Use XINT, not XUINT.
18337 There's no need for unsigned here.
18339 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18340 This follows up to the 2011-05-06 change that substituted uintptr_t
18341 for EMACS_INT. This case wasn't caught back then.
18343 Rework Fformat to avoid integer overflow issues.
18344 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18345 now (part of C89). Include <verify.h>.
18346 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18347 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18348 (Fformat): Avoid the prepass trying to compute sizes; it was only
18349 approximate and thus did not catch overflow reliably. Instead, walk
18350 through the format just once, formatting and computing sizes as we go,
18351 checking for integer overflow at every step, and allocating a larger
18352 buffer as needed. Keep track separately whether the format is
18353 multibyte. Keep only the most-recently calculated precision, rather
18354 than them all. Record whether each argument has been converted to
18355 string. Use EMACS_INT, not int, for byte and char and arg counts.
18356 Support field widths and precisions larger than INT_MAX. Avoid
18357 sprintf's undefined behavior with conversion specifications such as %#d
18358 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18359 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18360 formatting out-of-range floating point numbers with int
18361 formats. (Bug#8668)
18363 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18365 * data.c: Avoid integer truncation in expressions involving floats.
18366 * data.c: Include <intprops.h>.
18367 (arith_driver): When there's an integer overflow in an expression
18368 involving floating point, convert the integers to floating point
18369 so that the resulting value does not suffer from catastrophic
18370 integer truncation. For example, on a 64-bit host (* 4
18371 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18372 Do not rely on undefined behavior after integer overflow.
18374 merge count_size_as_multibyte, parse_str_to_multibyte
18375 * character.c, character.h (count_size_as_multibyte):
18376 Rename from parse_str_to_multibyte; all uses changed.
18377 Check for integer overflow.
18378 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18379 since it's now a duplicate of the other. This is more of
18380 a character than a buffer op, so better that it's in character.c.
18381 * fns.c, print.c: Adjust to above changes.
18383 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18385 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18387 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18389 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18390 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18391 (x_clipboard_manager_save): Now static.
18392 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18394 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18395 (crypto_hash_function): Now static.
18396 Fix pointer signedness problems. Avoid unnecessary initializations.
18398 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18400 * termhooks.h (Vselection_alist): Make it terminal-local.
18402 * terminal.c (create_terminal): Initialize it.
18404 * xselect.c: Support for clipboard managers.
18405 (Vselection_alist): Move to termhooks.h as terminal-local var.
18406 (LOCAL_SELECTION): New macro.
18407 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18408 (symbol_to_x_atom): Remove gratuitous arg.
18409 (x_handle_selection_request, lisp_data_to_selection_data)
18410 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18411 (x_own_selection, x_get_local_selection, x_convert_selection):
18412 New arg, specifying work frame. Use terminal-local Vselection_alist.
18413 (some_frame_on_display): Delete unused function.
18414 (Fx_own_selection_internal, Fx_get_selection_internal)
18415 (Fx_disown_selection_internal, Fx_selection_owner_p)
18416 (Fx_selection_exists_p): New optional frame arg.
18417 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18418 (x_handle_selection_clear): Don't treat other terminals with the
18419 same keyboard specially. Use the terminal-local Vselection_alist.
18420 (x_clear_frame_selections): Use Frun_hook_with_args.
18422 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18424 * xterm.h: Add support for those atoms.
18426 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18428 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18429 (converted_selections, conversion_fail_tag): New global variables.
18430 (x_selection_request_lisp_error): Free the above.
18431 (x_get_local_selection): Remove unnecessary code.
18432 (x_reply_selection_request): Args changed; handle arbitrary array
18433 of converted selections stored in converted_selections.
18434 Separate the XChangeProperty and SelectionNotify steps.
18435 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18436 (x_convert_selection): New function.
18437 (x_handle_selection_event): Simplify.
18438 (x_get_foreign_selection): Don't ignore incoming requests while
18439 waiting for an answer; this will fail when we implement
18440 SAVE_TARGETS, and seems unnecessary anyway.
18441 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18442 (Vx_sent_selection_functions): Doc fix.
18444 2011-05-26 Leo Liu <sdl.web@gmail.com>
18446 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18448 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18450 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18452 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18453 for fringe update if it has periodic bitmap.
18454 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18455 and fringe_bitmap_periodic_p.
18457 * fringe.c (get_fringe_bitmap_data): New function.
18458 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18459 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18460 row. Mark glyph row for fringe update if periodicity changed.
18462 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18463 for fringe update unless it has periodic bitmap.
18465 2011-05-25 Kenichi Handa <handa@m17n.org>
18467 * xdisp.c (get_next_display_element): Set correct it->face_id for
18468 a static composition.
18470 2011-05-24 Leo Liu <sdl.web@gmail.com>
18473 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18475 * fns.c (crypto_hash_function, Fsha1): New function.
18476 (Fmd5): Use crypto_hash_function.
18477 (syms_of_fns): Add Ssha1.
18479 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18481 * gnutls.c: Remove unused macros.
18482 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18483 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18484 Remove macros that are defined and never used.
18485 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18487 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18489 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18490 (Fx_get_selection_internal): Minor cleanup.
18491 (Fx_own_selection_internal): Rename arguments for consistency with
18494 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18496 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18498 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18500 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18502 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18504 * dispnew.c (scrolling_window): Don't exclude the case that the
18505 last enabled row in the desired matrix touches the bottom boundary.
18507 2011-05-21 Glenn Morris <rgm@gnu.org>
18509 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18510 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18511 and add some more files.
18513 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18515 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18516 report_file_error introduced by the change from 2011-05-07.
18518 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18520 * systime.h (Time): Define only if emacs is defined.
18521 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18522 where the include path doesn't have X11/X.h by default. See
18523 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18525 2011-05-20 Kenichi Handa <handa@m17n.org>
18527 * composite.c (find_automatic_composition): Fix previous change.
18529 2011-05-20 Glenn Morris <rgm@gnu.org>
18531 * lisp.mk: New file, split from Makefile.in.
18532 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18533 (shortlisp): Remove.
18534 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18536 2011-05-19 Glenn Morris <rgm@gnu.org>
18538 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18539 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18540 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18541 (lisp): Set the order to that of loadup.el.
18542 (shortlisp): Make it a copy of $lisp.
18543 (SOME_MACHINE_LISP): Remove.
18544 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18545 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18547 2011-05-18 Kenichi Handa <handa@m17n.org>
18549 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18550 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18551 (find_automatic_composition): Mostly rewrite for efficiency.
18553 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18555 * makefile.w32-in: Update dependencies.
18557 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18559 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18560 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18562 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18564 Fix some integer overflow issues, such as string length overflow.
18566 * insdel.c (count_size_as_multibyte): Check for string overflow.
18568 * character.c (lisp_string_width): Check for string overflow.
18569 Use EMACS_INT, not int, for string indexes and lengths; in
18570 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18571 the resulting string length overflows an EMACS_INT; instead,
18572 report a string overflow if no precision given. When checking for
18573 precision exhaustion, use a check that cannot possibly have
18574 integer overflow. (Bug#8675)
18575 * character.h (lisp_string_width): Adjust to new signature.
18577 * alloc.c (string_overflow): New function.
18578 (Fmake_string): Use it. This doesn't change behavior, but saves
18579 a few bytes and will simplify future changes.
18580 * character.c (string_escape_byte8): Likewise.
18581 * lisp.h (string_overflow): New decl.
18583 Fixups, following up to the user-interface timestamp change.
18584 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18585 for UI timestamps, instead of unsigned long.
18586 * msdos.c (mouse_get_pos): Likewise.
18587 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18588 * w32gui.h (Time): Define by including "systime.h" rather than by
18589 declaring it ourselves. (Bug#8664)
18591 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18592 * image.c (clear_image_cache): Likewise.
18594 * term.c (term_mouse_position): Don't assume time_t wraparound.
18596 Be more systematic about user-interface timestamps.
18597 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18598 and sometimes 'EMACS_UINT', to represent these timestamps.
18599 This change causes it to use 'Time' uniformly, as that's what X uses.
18600 This makes the code easier to follow, and makes it easier to catch
18601 integer overflow bugs such as Bug#8664.
18602 * frame.c (Fmouse_position, Fmouse_pixel_position):
18603 Use Time, not unsigned long, for user-interface timestamps.
18604 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18605 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18606 * keyboard.h (last_event_timestamp): Likewise.
18607 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18608 * menu.h (xmenu_show): Likewise.
18609 * term.c (term_mouse_position): Likewise.
18610 * termhooks.h (struct input_event.timestamp): Likewise.
18611 (struct terminal.mouse_position_hook): Likewise.
18612 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18613 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18614 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18615 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18616 what it was before.
18617 * menu.h, termhooks.h: Include "systime.h", for Time.
18619 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18620 Don't assume that the difference between two unsigned long values
18621 can fit into an integer. At this point, we know button_down_time
18622 <= event->timestamp, so the difference must be nonnegative, so
18623 there's no need to cast the result if double-click-time is
18624 nonnegative, as it should be; check that it's nonnegative, just in
18625 case. This bug is triggered when events are more than 2**31 ms
18626 apart (about 25 days). (Bug#8664)
18628 * xselect.c (last_event_timestamp): Remove duplicate decl.
18629 (x_own_selection): Remove needless cast to unsigned long.
18631 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18632 that always fit in int. Use a sentinel instead of a counter, to
18633 avoid a temp and to allay GCC's concerns about possible int overflow.
18634 * frame.h (struct frame): Use int for menu_bar_items_used
18635 instead of EMACS_INT, since it always fits in int.
18637 * menu.c (grow_menu_items): Check for int overflow.
18639 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18641 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18642 Before, the code was not consistent. These values cannot exceed
18643 2**31 - 1 so there's no need to make them unsigned.
18644 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18645 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18646 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18648 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18650 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18651 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18652 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18653 presumably because the widths might not match.
18655 * window.c (size_window): Avoid needless test at loop start.
18657 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18659 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18661 2011-05-12 Drew Adams <drew.adams@oracle.com>
18663 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18665 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18667 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18668 `width' to `bar_area_x' and `bar_area_width', respectively.
18669 (x_scroll_run): Take account of fringe background extension.
18671 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18672 Rename local vars `left' and `width' to `bar_area_x' and
18673 `bar_area_width', respectively.
18674 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18675 background extension.
18677 2011-05-10 Jim Meyering <meyering@redhat.com>
18679 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18681 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18683 * image.c (Finit_image_library): Return t for built-in image types,
18684 like pbm and xbm. (Bug#8640)
18686 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18688 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18690 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18692 * w32console.c (Fset_screen_color): Doc fix.
18693 (Fget_screen_color): New function.
18694 (syms_of_ntterm): Defsubr it.
18696 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18697 unlink the temporary file if Fcall_process didn't create it in the
18699 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18700 child process will be redirected to a file specified with `:file'.
18701 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18702 cue to call_process_cleanup not to close that handle.
18704 2011-05-07 Ben Key <bkey76@gmail.com>
18706 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18707 one of two shell specific rules, either bootstrap-temacs-CMD or
18708 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18709 to the previous implementation of the bootstrap-temacs rule.
18710 The bootstrap-temacs-CMD rule is similar to the previous
18711 implementation of the bootstrap-temacs rule except that it
18712 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18715 These changes, along with some changes to nt/configure.bat,
18716 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18717 earlier fix to add support for --cflags and --ldflags options
18718 that include quotes so that it works whether make uses cmd or
18721 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18723 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18724 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18726 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18727 a string. Handle both cases.
18728 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18729 (Fdbus_register_method): Use Qinvalid_function.
18731 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18733 * makefile.w32-in: Update dependencies.
18734 (LISP_H): Add inttypes.h and stdin.h.
18735 (PROCESS_H): Add unistd.h.
18737 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18739 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18740 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18742 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18744 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18746 * term.c (vfatal): Remove stray call to va_end.
18747 It's not needed and the C Standard doesn't allow it here anyway.
18749 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18750 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18752 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18755 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18757 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18759 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18761 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18763 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18765 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18766 * charset.c (Fdefine_charset_internal): Don't initialize
18767 charset.code_space[15]. The value was garbage, on hosts with
18768 32-bit int (Bug#8600).
18770 * lread.c (read_integer): Be more consistent with string-to-number.
18771 Use string_to_number to do the actual conversion; this avoids
18772 rounding errors and fixes some other screwups. Without this fix,
18773 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18774 (digit_to_number): Move earlier, for benefit of read_integer.
18775 Return -1 if the digit is out of range for the base, -2 if it is
18776 not a digit in any supported base. (Bug#8602)
18778 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18780 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18781 to match comment at start of function. This also removes a
18782 GCC warning about overflow in a 32+64-bit port.
18784 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18786 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18787 Reported by Stefan Monnier in
18788 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18789 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18790 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18792 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18793 (EMACS_UINTPTR): Likewise, with uintptr_t.
18795 * lisp.h: Prefer 64-bit EMACS_INT if available.
18796 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18797 on 32-bit hosts that have 64-bit int, so that they can access
18799 However, temporarily disable this change unless the temporary
18800 symbol WIDE_EMACS_INT is defined.
18802 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18804 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18805 This removes an assumption that EMACS_INT and long are the same
18806 width as pointers. The assumption is true for Emacs porting targets
18807 now, but we want to make other targets possible.
18808 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18809 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18810 In the rest of the code, change types of integers that hold casted
18811 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18812 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18813 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18814 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18815 No need to cast type when ORing.
18816 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18817 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18818 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18819 assume EMACS_INT is the same width as char *.
18820 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18821 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18822 Remove no-longer-needed casts.
18823 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18824 (xg_tool_bar_help_callback, xg_make_tool_item):
18825 Use EMACS_INTPTR to hold an integer
18826 that will be cast to void *; this can avoid a GCC warning
18827 if EMACS_INT is not the same width as void *.
18828 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18829 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18830 (current_message_1, set_message_1):
18831 Use a local to convert to proper width without a cast.
18832 * xmenu.c (dialog_selection_callback): Likewise.
18834 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18835 Also, don't assume VALBITS / RAND_BITS is less than 5,
18836 and don't rely on undefined behavior when shifting a 1 left into
18838 * lisp.h (get_random): Change signature to match.
18840 * lread.c (hash_string): Use size_t, not int, for hash computation.
18841 Normally we prefer signed values; but hashing is special, because
18842 it's better to use unsigned division on hash table sizes so that
18843 the remainder is nonnegative. Also, size_t is the natural width
18844 for hashing into memory. The previous code used 'int', which doesn't
18845 retain enough info to hash well into very large tables.
18846 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18848 * dbusbind.c: Don't possibly lose pointer info when converting.
18849 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18850 Use XPNTR rather than XHASH, so that the high-order bits of
18851 the pointer aren't lost when converting through void *.
18853 * eval.c (Fautoload): Don't double-shift a pointer.
18855 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18857 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18859 * gnutls.c (DEF_GNUTLS_FN):
18860 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18862 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18864 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18867 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18869 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18870 New version that can reserve upto 2GB of heap space.
18872 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18874 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18876 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18878 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18879 `gnutls_certificate_set_x509_key_file'.
18881 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18883 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18884 Update dependencies.
18886 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18888 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18889 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18890 Remove unused parameter `fildes'.
18891 * process.c (read_process_output, send_process): Don't pass it.
18893 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18895 Fix previous change: the library cache is defined in w32.c.
18896 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18897 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18899 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18901 Implement dynamic loading of GnuTLS on Windows.
18903 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18904 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18905 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18908 * gnutls.c (Qgnutls_dll): Define.
18909 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18910 (gnutls_*): Declare function pointers.

18914 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18915 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18916 (emacs_gnutls_write, emacs_gnutls_read)
18917 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18918 (Fgnutls_available_p): New function.
18919 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

18927 (w32_delayed_load): Move to w32.c.
18929 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18931 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18932 (w32_delayed_load): Move from image.c. When loading a library, record
18933 its filename in the :loaded-from property of the library id.
18934 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18935 Initialize and staticpro them.
18936 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18938 * process.c: Include lisp.h before w32.h, not after.
18939 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18940 instead of gnutls_record_check_pending.
18942 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18944 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18946 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18947 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18950 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18952 * xterm.c (x_set_frame_alpha): Do not set property on anything
18953 else than FRAME_X_OUTER_WINDOW (Bug#8608).
18955 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18957 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
18959 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18961 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

18975 * sysdep.c (wait_for_termination_1): Make static.
18976 (wait_for_termination, interruptible_wait_for_termination):
18977 Move after wait_for_termination_1.
18979 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18981 * sysdep.c (interruptible_wait_for_termination): New function
18982 which is like wait_for_termination, but allows keyboard
18985 * callproc.c (Fcall_process): Add (:file "file") as an option for
18987 (Fcall_process_region): Ditto.
18989 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18991 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18992 rather than `XVECTOR (FOO)->size'.
18994 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18995 inttypes.h, as a gnulib replacement is used if it not available in
18998 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19000 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19001 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19002 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19004 * coding.c (coding_alloc_by_realloc): Error out if destination
19005 will grow beyond MOST_POSITIVE_FIXNUM.
19006 (decode_coding_emacs_mule): Abort if there isn't enough place in
19007 charbuf for the composition carryover bytes. Reserve an extra

19015 aborting when %lld or %lll format is passed.
19016 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19017 %llo or %llx format is passed. (Bug#8545)
19019 * window.c (window_scroll_line_based): Use a marker instead of
19020 simple variables to record original value of point. (Bug#7952)
19022 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19023 produced by %s or %c overflows available buffer space. (Bug#8545)
19025 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19027 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19028 (SIZE_MAX): Move defn after all includes, as they might #define it.
19030 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19032 * w32.c (init_environment): Warn about defaulting HOME to C:\.

19052 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19054 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19056 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19058 * makefile.w32-in: Update dependencies.
19060 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19062 Improve `doprnt' and its usage. (Bug#8545)
19063 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19064 `format_end'. Remove support for %l as a conversion specifier.
19065 Don't use xrealloc. Improve diagnostics when the %l size modifier
19066 is used. Update the commentary.
19068 * eval.c (verror): Simplify calculation of size_t.
19070 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19073 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19075 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19078 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19080 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19081 This makes this file independent of the recent pseudovector change.
19083 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19085 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19087 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19088 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19089 Remove unused local.
19090 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19092 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19093 GCC 4.6.0 optimizes based on type-based alias analysis.
19094 For example, if b is of type struct buffer * and v of type struct
19095 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19096 != &v->size, and therefore "v->size = 1; b->size = 2; return
19097 v->size;" must therefore return 1. This assumption is incorrect
19098 for Emacs, since it type-puns struct Lisp_Vector * with many other
19099 types. To fix this problem, this patch adds a new type struct
19100 vectorlike_header that documents the constraints on layout of vectors
19101 and pseudovectors, and helps optimizing compilers not get fooled
19102 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19103 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19104 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19106 (XSETPVECTYPE): Rewrite in terms of new macro.
19107 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19108 This is a bit clearer, and further avoids the possibility of
19109 undesirable aliasing.
19110 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19111 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19112 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19113 since Lisp_Subr is a special case (no "next" field).
19114 (ASIZE): Now uses header.size rather than size.
19115 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19116 to avoid the hassle of writing XVECTOR (foo)->header.size.
19117 (struct vectorlike_header): New type.
19118 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19119 object, to help avoid aliasing.
19120 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19121 (SUBRP): Likewise, since Lisp_Subr is a special case.
19122 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19123 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19124 (struct Lisp_Hash_Table): Combine first two members into a single
19125 struct vectorlike_header member. All uses of "size" and "next" members
19126 changed to be "header.size" and "header.next".
19127 * buffer.h (struct buffer): Likewise.
19128 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19129 * frame.h (struct frame): Likewise.
19130 * process.h (struct Lisp_Process): Likewise.
19131 * termhooks.h (struct terminal): Likewise.
19132 * window.c (struct save_window_data, struct saved_window): Likewise.
19133 * window.h (struct window): Likewise.
19134 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19135 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19136 * buffer.c (init_buffer_once): Likewise.
19137 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19139 * process.c (Fformat_network_address): Use local var for size,
19142 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19144 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19145 * data.c (atof): Remove decl; no longer used or needed.
19146 (digit_to_number): Move to lread.c.
19147 (Fstring_to_number): Use new string_to_number function, to be
19148 consistent with how the Lisp reader treats infinities and NaNs.
19149 Do not assume that floating-point numbers represent EMACS_INT
19150 without losing information; this is not true on most 64-bit hosts.
19151 Avoid double-rounding errors, by insisting on integers when
19152 parsing non-base-10 numbers, as the documentation specifies.
19153 * lisp.h (string_to_number): New decl, replacing ...
19154 (isfloat_string): Remove.
19155 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19156 (read1): Do not accept +. and -. as integers; this
19157 appears to have been a coding error. Similarly, do not accept
19158 strings like +-1e0 as floating point numbers. Do not report
19159 overflow for integer overflows unless the base is not 10 which
19160 means we have no simple and reliable way to continue.
19161 Break out the floating-point parsing into a new
19162 function string_to_number, so that Fstring_to_number parses
19163 floating point numbers consistently with the Lisp reader.
19164 (digit_to_number): Move here from data.c. Make it static inline.
19165 (E_CHAR, EXP_INT): Remove, replacing with ...
19166 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19167 (string_to_number): New function, replacing isfloat_string.
19168 This function checks for valid syntax and produces the resulting
19169 Lisp float number too. Rework it so that string-to-number
19170 no longer mishandles examples like "1.0e+". Use strtoumax,
19171 so that overflow for non-base-10 numbers is reported only when
19172 there's no portable and simple way to convert to floating point.
19174 * textprop.c (set_text_properties_1): Rewrite for clarity,
19175 and to avoid GCC warning about integer overflow.
19177 * intervals.h (struct interval): Use EMACS_INT for members
19178 where EMACS_UINT might cause problems. See
19179 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19180 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19181 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19183 (offset_intervals): Tell GCC not to worry about length overflow
19184 when negating a negative length.
19186 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19187 (overrun_check_free): Likewise.
19189 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19190 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19193 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19194 (gnutls_make_error): Rename local to avoid shadowing.
19195 (gnutls_emacs_global_deinit): ifdef out; not used.
19196 (Fgnutls_boot): Use const for pointer to readonly storage.
19197 Comment out unused local. Fix pointer signedness problems.
19199 * lread.c (openp): Don't stuff size_t into an 'int'.
19200 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19201 about possible signed overflow.
19203 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19204 (GDK_KEY_g): Don't define if already defined.
19205 (xg_prepare_tooltip): Avoid pointer signedness problem.
19206 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19208 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19209 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19211 * xfns.c (Fx_window_property): Simplify a bit,
19212 to make a bit faster and to avoid GCC 4.6.0 warning.
19213 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19215 * fns.c (internal_equal): Don't assume size_t fits in int.
19217 * alloc.c (compact_small_strings): Tighten assertion a little.
19219 Replace pEd with more-general pI, and fix some printf arg casts.
19220 * lisp.h (pI): New macro, generalizing old pEd macro to other
19221 conversion specifiers. For example, use "...%"pI"d..." rather
19222 than "...%"pEd"...".
19223 (pEd): Remove. All uses replaced with similar uses of pI.
19224 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19225 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19226 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19227 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19228 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19229 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19230 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19232 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19233 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19234 * print.c (safe_debug_print, print_object): Likewise.
19235 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19237 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19238 avoiding the 0 flag, which is not portable.
19239 * process.c (Fmake_network_process): Use pI to avoid cast.
19240 * region-cache.c (pp_cache): Likewise.
19241 * xdisp.c (decode_mode_spec): Likewise.
19242 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19243 behavior on 64-bit hosts with printf arg.
19244 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19245 (x_stop_queuing_selection_requests): Likewise.
19246 (x_get_window_property): Don't truncate byte count to an 'int'
19249 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19250 here, since it parses constructs like leading '-' and spaces,
19251 which are not wanted; and it overflows with large numbers.
19252 Instead, simply match F[0-9]+, which is what is wanted anyway.
19254 * alloc.c: Remove unportable assumptions about struct layout.
19255 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19256 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19257 (allocate_vectorlike, make_pure_vector): Use the new macros,
19258 plus offsetof, to remove unportable assumptions about struct layout.
19259 These assumptions hold on all porting targets that I know of, but
19260 they are not guaranteed, they're easy to remove, and removing them
19261 makes further changes easier.
19263 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19264 This doesn't fix a bug but makes the code clearer.
19265 (string_overrun_cookie): Now const. Use initializers that
19266 don't formally overflow signed char, to avoid warnings.
19267 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19268 can cause Emacs to crash when string overrun checking is enabled.
19269 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19270 multiple of sizeof (EMACS_INT); it need not be, if
19271 alignof(EMACS_INT) < sizeof (EMACS_INT).
19272 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19274 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19281 supposed to be handshaking. (Bug#8556)
19282 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19284 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

19295 (check_string_free_list): Convert to standard C.
19297 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19299 * w32.c (emacs_gnutls_push): Fix typo.
19301 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19303 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19304 "cast to pointer from integer of different size".
19306 Improve doprnt and its use in verror. (Bug#8545)
19307 * doprnt.c (doprnt): Document the set of format control sequences
19308 supported by the function. Use SAFE_ALLOCA instead of always
19311 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19312 is one byte too soon. Don't use xrealloc; instead xfree and
19315 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19317 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19320 * gnutls.c: Renamed global_initialized to
19321 gnutls_global_initialized. Added internals for the
19322 :verify-hostname-error, :verify-error, and :verify-flags
19323 parameters of `gnutls-boot' and documented those parameters in the
19324 docstring. Start callback support.
19325 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19326 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19327 on error. Return error code.

19329 (emacs_gnutls_read): Likewise.
19330 (Fgnutls_boot): Return handshake error code.
19331 (emacs_gnutls_handle_error): New function.

19387 changes in globals.h immediately force recompilation.
19388 (TAGS): Depend on $(CURDIR)/m/intel386.h and
19389 $(CURDIR)/s/ms-w32.h.

19394 <char-direction-table>: Deleted.
19396 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19398 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19399 * doprnt.c: Include limits.h.
19400 (SIZE_MAX): New macro.
19401 (doprnt): Return a size_t value. 2nd arg is now size_t.
19402 Many local variables are now size_t instead of int or unsigned.
19403 Improve overflow protection. Support `l' modifier for integer
19404 conversions. Support %l conversion. Don't assume an EMACS_INT
19405 argument for integer conversions and for %c.
19407 * lisp.h (doprnt): Restore prototype.
19409 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19410 $(SRC)/character.h.
19412 * Makefile.in (base_obj): Add back doprnt.o.
19414 * deps.mk (doprnt.o): Add back prerequisites.
19415 (callint.o): Depend on character.h.
19417 * eval.c (internal_lisp_condition_case): Include the handler
19418 representation in the error message.
19419 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19420 when breaking from the loop.

19424 * callint.c (Fcall_interactively): When displaying error message
19425 about invalid control letter, pass the character's codepoint, not
19426 a pointer to its multibyte form. Improve display of the character
19427 in octal and display also its hex code.
19429 * character.c (char_string): Use %x to display the (unsigned)
19430 codepoint of an invalid character, to avoid displaying a bogus
19433 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19434 `error', not SYMBOL_NAME itself.
19436 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19437 character arguments to `error'.
19439 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19440 to `error' in error message about FINAL_CHAR argument. Make sure
19441 FINAL_CHAR is a character, and use %c when it is passed as
19442 argument to `error'.

19506 Define only if needed.
19508 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
19509 by pacifying GCC about it. Maybe it's time to retire it?
19510 * xfaces.c (USG, __TIMEVAL__): Likewise.
19512 * dispextern.h (struct redisplay_interface): Rename param
19513 to avoid shadowing.
19514 * termhooks.h (struct terminal): Likewise.
19515 * xterm.c (xembed_send_message): Likewise.
19517 * insdel.c (make_gap_smaller): Define only if
19518 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
19520 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
19523 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
19524 so that we aren't warned about unused symbols.
19526 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
19528 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
19530 * xfns.c (x_real_positions): Mark locals as initialized.
19532 * xmenu.c (xmenu_show): Don't use uninitialized vars.
19534 * xterm.c: Fix problems found by static analysis with other toolkits.
19535 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
19536 (x_dispatch_event): Declare static if USE_GTK, and
19537 define if USE_GTK || USE_X_TOOLKIT.
19538 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
19539 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
19540 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
19541 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
19543 * xmenu.c (menu_help_callback): Pointer type fixes.
19544 Use const pointers when pointing at readonly data. Avoid pointer

19560 * bitmaps: Change bitmaps from unsigned char back to the X11
19561 compatible char. Avoid the old compiler warnings about
19562 out-of-range initializers by using, for example, '\xab' rather
19565 * xgselect.c (xgselect_initialize): Check vs interface

19636 --enable-checking=xmallocoverrun). xfree is now used to
19637 deallocate these memory blocks.

20003 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20005 alloc.c: Import and export fewer symbols, and remove unused items.
20006 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20008 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20009 it's not optimized away by whole-program optimization.
20010 (message_enable_multibyte, free_misc): Remove.
20011 (catchlist, handlerlist, mark_backtrace):
20012 Declare only if BYTE_MARK_STACK.
20013 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
20014 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
20015 (message_enable_multibyte): Remove decl.
20016 (free_misc, interval_free_list, float_block, float_block_index):
20017 (n_float_blocks, float_free_list, cons_block, cons_block_index):
20018 (cons_free_list, last_marked_index):
20020 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
20021 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
20022 (mark_backtrace): Define only if BYTE_MARK_STACK.
20023 * xdisp.c (message_enable_multibyte): Now static.
20025 Declare Lisp_Object Q* variables to be 'static' if not exported.
20026 This makes it easier for human readers (and static analyzers)
20027 to see whether these variables are used from other modules.
20028 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
20029 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
20030 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
20031 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
20032 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
20033 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
20034 * xmenu.c, xselect.c:
20035 Declare Q* vars static if they are not used in other modules.
20036 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
20037 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
20038 Remove decls of unexported vars.
20039 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20041 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20043 Make Emacs functions such as Fatom 'static' by default.
20044 This makes it easier for human readers (and static analyzers)
20045 to see whether these functions can be called from other modules.
20046 DEFUN now defines a static function. To make the function external
20047 so that it can be used in other C modules, use the new macro DEFUE.
20048 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20049 (Finit_image_library):
20050 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
20051 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
20052 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
20053 Remove decls, since these functions are now static.
20054 (Funintern, Fget_internal_run_time): New decls, since these functions
20055 were already external.
20057 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
20058 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
20059 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
20060 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
20061 * keyboard.c, keymap.c, lread.c:
20062 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
20063 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
20064 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
20065 Mark functions with DEFUE instead of DEFUN,
20066 if they are used in other modules.
20067 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20068 decls for now-static functions.
20069 * buffer.h (Fdelete_overlay): Remove decl.
20070 * callproc.c (Fgetenv_internal): Mark as internal.
20071 * composite.c (Fremove_list_of_text_properties): Remove decl.

20075 * doc.c (Fdocumntation_property): New forward static decl.
20076 * eval.c (Ffetch_bytecode): New forward static decl.
20077 (Funintern): Remove extern decl; now in .h file where it belongs.
20078 * fileio.c (Fmake_symbolic_link): New forward static decl.
20079 * image.c (Finit_image_library): New forward static decl.
20080 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
20081 * intervals.h (Fprevious_property_change):
20082 (Fremove_list_of_text_properties): Remove decls.
20083 * keyboard.c (Fthis_command_keys): Remove decl.
20084 (Fcommand_execute): New forward static decl.
20085 * keymap.c (Flookup_key): New forward static decl.
20086 (Fcopy_keymap): Now static.
20087 * keymap.h (Flookup_key): Remove decl.
20088 * process.c (Fget_process): New forward static decl.
20089 (Fprocess_datagram_address): Mark as internal.

20100 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
20102 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
20105 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20107 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20108 when at ZV. (Bug#8487)
20110 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20112 * charset.c (Fclear_charset_maps): Use xfree instead of free.
20114 * keyboard.c (parse_tool_bar_item): Likewise.
20115 * sound.c (sound_cleanup, alsa_close): Likewise.
20116 * termcap.c (tgetent): Likewise.
20117 * xfns.c (x_default_font_parameter): Likewise.
20118 * xsettings.c (read_and_apply_settings): Likewise.
20120 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20121 (overrun_check_free): Protoize.
20123 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20125 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20126 since callers should never pass a negative size.
20127 Change the signature to match that of plain 'read' and 'write'; see
20128 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20129 * lisp.h: Update prototypes of emacs_write and emacs_read.
20131 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20133 * xdisp.c (redisplay_window): Don't try to determine the character
20134 position of the scroll margin if the window start point w->startp
20135 is outside the buffer's accessible region. (Bug#8468)
20137 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20139 Fix write-region and its subroutines for buffers > 2GB.
20140 * fileio.c (a_write, e_write): Modify declaration of arguments and
20141 local variables to support buffers larger than 2GB.
20142 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20144 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20145 argument, local variables, and return value.
20147 * lisp.h: Update prototypes of emacs_write and emacs_read.
20149 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20151 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20153 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20155 Fix more problems found by GCC 4.6.0's static checks.
20157 * xdisp.c (vmessage): Use a better test for character truncation.
20159 * charset.c (load_charset_map): <, not <=, for optimization,
20160 and to avoid potential problems with integer overflow.
20161 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20162 * casetab.c (set_identity, shuffle): Likewise.
20163 * editfns.c (Fformat): Likewise.
20164 * syntax.c (skip_chars): Likewise.
20166 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20167 This also lets GCC 4.6.0 generate slightly better loop code.
20169 * callint.c (Fcall_interactively): <, not <=, for optimization.
20170 (Fcall_interactively): Count the number of arguments produced,
20171 not the number of arguments given. This is simpler and lets GCC
20172 4.6.0 generate slightly better code.
20174 * ftfont.c: Distingish more carefully between FcChar8 and char.
20175 The previous code passed unsigned char * to a functions like
20176 strlen and xstrcasecmp that expect char *, which does not
20177 conform to the C standard.
20178 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20179 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20180 char * when the C standard requires it.
20182 * keyboard.c (read_char): Remove unused var.
20184 * eval.c: Port to Windows vsnprintf (Bug#8435).
20185 Include <limits.h>.
20186 (SIZE_MAX): Define if the headers do not.
20187 (verror): Do not give up if vsnprintf returns a negative count.
20188 Instead, grow the buffer. This ports to Windows vsnprintf, which
20189 does not conform to C99. Problem reported by Eli Zaretskii.
20190 Also, simplify the allocation scheme, by avoiding the need for
20191 calling realloc, and removing the ALLOCATED variable.
20193 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20195 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20196 But keep the doprint source code for now, as we might revamp it
20197 and use it again (Bug#8435).
20198 * lisp.h (doprnt): Remove.
20199 * Makefile.in (base_obj): Remove doprnt.o.
20200 * deps.mk (doprnt.o): Remove.
20202 error: Print 32- and 64-bit integers portably (Bug#8435).
20203 Without this change, on typical 64-bit hosts error ("...%d...", N)
20204 was used to print both 32- and 64-bit integers N, which relied on
20205 undefined behavior.
20206 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20207 * lisp.h (error, verror): Mark as printf-like functions.
20208 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20209 Report overflow in size calculations when allocating printf buffer.
20210 Do not truncate output string at its first null byte.
20211 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20212 Truncate the output at a character boundary, since vsnprintf does not
20214 * charset.c (check_iso_charset_parameter): Convert internal
20215 character to string before calling 'error', since %c now has the
20217 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20218 overflow when computing char to be passed to 'error'. Do not
20219 pass Lisp_Object to 'error'; pass the integer instead.
20220 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20221 formatted with plain %d.
20223 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20225 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20227 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20229 * xterm.c (x_catch_errors): Remove duplicate declaration.
20231 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20233 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20235 2011-04-10 Jim Meyering <meyering@redhat.com>
20237 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20238 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20239 return ssize_t not "int", and use size_t as the buffer length.
20240 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20241 * gnutls.h: Update declarations.
20242 * process.c (read_process_output): Use ssize_t, to match.
20243 (send_process): Likewise.
20245 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20247 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20249 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20251 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20252 Use unsigned char, to match FcChar8 type definition.
20254 * xterm.c (handle_one_xevent):
20255 * xmenu.c (create_and_show_popup_menu):
20256 * xselect.c (x_decline_selection_request)
20257 (x_reply_selection_request): Avoid type-punned deref of X events.
20259 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20261 Fix some uses of `int' instead of EMACS_INT.
20262 * search.c (string_match_1, fast_string_match)
20263 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20264 (scan_buffer, find_next_newline_no_quit)
20265 (find_before_next_newline, search_command, Freplace_match)
20266 (Fmatch_data): Make some `int' variables be EMACS_INT.
20268 * xdisp.c (display_count_lines): 3rd argument and return value now
20269 EMACS_INT. All callers changed.
20270 (pint2hrstr): Last argument is now EMACS_INT.
20272 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20273 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20274 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20275 (decode_coding_utf_16, decode_coding_emacs_mule)
20276 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
20277 (decode_coding_ccl, decode_coding_charset)
20278 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
20279 (decode_coding_iso_2022, decode_coding_emacs_mule)
20280 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
20281 <char_offset, last_offset>: Declare EMACS_INT.
20282 (encode_coding_utf_8, encode_coding_utf_16)
20283 (encode_coding_emacs_mule, encode_invocation_designation)
20284 (encode_designation_at_bol, encode_coding_iso_2022)
20285 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20286 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20288 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20289 (encode_invocation_designation): Last argument P_NCHARS is now
20291 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20292 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20294 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20297 * ccl.c (Fccl_execute_on_string): Declare some variables
20300 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20302 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20304 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20306 * process.c (Fformat_network_address): Doc fix.
20308 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20310 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20312 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20314 * keyboard.c (read_char): Call Lisp function help-form-show,
20315 instead of using internal_with_output_to_temp_buffer.
20316 (Qhelp_form_show): New var.
20317 (syms_of_keyboard): Use DEFSYM macro.
20319 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20323 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
20325 * process.c (Flist_processes): Remove to Lisp.
20326 (list_processes_1): Delete.
20328 2011-04-06 Eli Zaretskii <eliz@gnu.org>
20330 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20332 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20334 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20336 Fix more problems found by GCC 4.6.0's static checks.
20338 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
20340 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20342 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20344 * xdisp.c (vmessage): Mark as a printf-like function.
20346 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
20348 * sound.c (sound_warning): Don't crash if arg contains a printf format.
20350 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
20351 printf-like functions.
20352 (tiff_load): Add casts to remove these marks before passing them
20353 to system-supplied API.
20355 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20357 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20358 This avoids several warnings with gcc -Wstrict-overflow.
20359 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20360 directly, rather than having caller test rule sign. This avoids
20361 some unnecessary tests.
20362 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20363 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20364 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20366 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20367 (xfont_open): Avoid unnecessary tests.
20369 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20371 * composite.h, composite.c (composition_gstring_put_cache):
20372 Use EMACS_INT, not int, for length.
20374 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20375 breaking out part of COMPOSITION_DECODE_RULE.
20376 (COMPOSITION_DECODE_RULE): Use it.
20377 * composite.c (get_composition_id): Remove unused local vars,
20378 by using the new macro.
20380 * textprop.c (set_text_properties_1): Change while to do-while,
20381 since the condition is always true at first.
20383 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20384 (interval_deletion_adjustment): Return unsigned value.
20387 * process.c (list_processes_1, create_pty, read_process_output):
20388 (exec_sentinel): Remove vars that were set but not used.
20389 (create_pty): Remove unnecessary "volatile"s.
20390 (Fnetwork_interface_info): Avoid possibility of int overflow.
20391 (read_process_output): Do adaptive read buffering even if carryover.
20392 (read_process_output): Simplify nbytes computation if buffered.
20394 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
20396 * syntax.c (scan_words): Remove var that was set but not used.
20397 (update_syntax_table): Use unsigned instead of int.
20399 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20400 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20401 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20403 * print.c (print_error_message): Avoid int overflow.
20405 * font.c (font_list_entities): Redo for clarity,
20406 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20408 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20409 (font_score): Avoid potential overflow in diff calculation.
20411 * fns.c (substring_both): Remove var that is set but not used.
20412 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20414 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20416 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20417 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20418 can always succeed if overflow has undefined behavior.
20420 * search.c (boyer_moore, wordify): Remove vars set but not used.
20421 (wordify): Omit three unnecessary tests.
20423 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20424 All callers changed. This avoids the need for an unused var.
20426 * casefiddle.c (casify_region): Remove var that is set but not used.
20428 * dired.c (file_name_completion): Remove var that is set but not used.
20430 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20432 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20433 (Finsert_file_contents): Remove unnecessary code checking fd.
20435 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20436 Check for integer overflow on size calculations.
20438 * buffer.c (Fprevious_overlay_change): Remove var that is set
20441 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20442 Remove vars that are set but not used.
20443 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20444 (timer_check_2): Mark vars as initialized.
20446 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20448 * image.c (lookup_image): Remove var that is set but not used.
20449 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20451 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20452 that are set but not used.
20454 * xfns.c (make_invisible_cursor): Don't return garbage
20455 if XCreateBitmapFromData fails (Bug#8410).
20457 * xselect.c (x_get_local_selection, x_handle_property_notify):
20458 Remove vars that are set but not used.
20460 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

20466 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20467 Check for overflow.
20469 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20470 (map_tty_color) [!defined MSDOS]: Likewise.
20472 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20474 * coding.c: Remove vars that are set but not used.
20475 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

20484 * print.c (print_object): Remove var that is set but not used.
20486 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20487 The gnulib version avoids calling malloc in the usual case,
20488 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20489 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20490 * filelock.c (current_lock_owner): Likewise.
20491 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20492 * sysdep.c: Include allocator.h, careadlinkat.h.
20493 (emacs_no_realloc_allocator): New static constant.
20494 (emacs_readlink): New function.
20495 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20496 ../lib/careadlinkat.h.
20498 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20500 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

20522 do not dereference NULL upon failed strdup
20523 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20524 (ns_get_family): Likewise.
20526 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20528 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20530 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20532 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20535 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20537 Add lexical binding.
20539 * window.c (Ftemp_output_buffer_show): New fun.

20548 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20550 (syms_of_lread): Declare `lexical-binding'.
20552 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20554 * keyboard.c (eval_dyn): New fun.
20555 (menu_item_eval_property): Use it.
20557 * image.c (parse_image_spec): Use Ffunctionp.
20559 * fns.c (concat, mapcar1): Accept byte-code-functions.
20561 * eval.c (Fsetq): Handle lexical vars.
20562 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20563 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20564 (FletX, Flet): Obey lexical binding.
20565 (Fcommandp): Handle closures.
20566 (Feval): New `lexical' arg.
20567 (eval_sub): New function extracted from Feval. Use it almost
20568 everywhere where Feval was used. Look up vars in lexical env.
20570 (Ffunctionp): Move from subr.el.
20571 (Ffuncall): Handle closures.
20572 (apply_lambda): Remove `eval_flags'.
20573 (funcall_lambda): Handle closures and new byte-code-functions.
20574 (Fspecial_variable_p): New function.
20575 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20576 but without exporting it to Lisp.
20578 * doc.c (Fdocumentation, store_function_docstring):
20579 * data.c (Finteractive_form): Handle closures.
20581 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20584 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20586 (exec_byte_code): New function extracted from Fbyte_code to handle new
20587 calling convention for byte-code-functions. Add new byte-codes.
20589 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20591 * alloc.c (Fmake_symbol): Init new `declared_special' field.

20595 * xdisp.c (redisplay_internal): Fix prototype.
20597 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20599 * xdisp.c (SCROLL_LIMIT): New macro.
20600 (try_scrolling): Use it when setting scroll_limit.
20601 Limit scrolling to 100 screen lines.
20602 (redisplay_window): Even when falling back on "recentering",
20603 position point in the window according to scroll-conservatively,
20604 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20606 (try_scrolling): When point is above the window, allow searching
20607 as far as scroll_max, or one screenful, to compute vertical
20608 distance from PT to the scroll margin position. This prevents
20609 try_scrolling from unnecessarily failing when
20610 scroll-conservatively is set to a value slightly larger than the
20611 window height. Clean up the case of PT below the margin at bottom
20612 of window: scroll_max can no longer be INT_MAX. When aggressive
20613 scrolling is in use, don't let point enter the opposite scroll
20614 margin as result of the scroll.
20615 (syms_of_xdisp) <scroll-conservatively>: Document the
20616 threshold of 100 lines for never-recentering scrolling.

20623 (message_log_check_duplicate): Remove parameters `prev_bol' and
20624 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20625 (redisplay_internal): Remove parameter `preserve_echo_area',
20626 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20628 * indent.c (Fvertical_motion):
20629 * window.c (window_scroll_pixel_based, Frecenter):
20630 Don't pass `need_y_p' to `move_it_by_lines'.
20632 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20634 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20635 steal a few bits to be more compact.
20636 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20637 Remove unneeded casts.
20639 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20641 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20643 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20644 binding" message (bug#7967).
20646 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20648 Fix more problems found by GCC 4.6.0's static checks.
20650 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20651 Remove unused local var.
20653 * editfns.c (Fmessage_box): Remove unused local var.
20655 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20656 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20657 Omit unused local vars.
20658 * window.c (shrink_windows): Omit unused local var.
20659 * menu.c (digest_single_submenu): Omit unused local var.
20660 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20661 Omit unused local var.
20663 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20664 Don't assume string length fits in int.
20665 (keyremap_step, read_key_sequence): Use size_t for sizes.

20669 instead of alloca (Bug#8344).
20671 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20672 (Fbacktrace_frame): Don't assume nframes fits in int.
20674 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

20681 * cm.c (calccost): Turn while-do into do-while, for clarity.
20683 * keyboard.c (syms_of_keyboard): Use the same style as later
20684 in this function when indexing through an array. This also
20685 works around GCC bug 48267.
20687 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20689 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20691 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20692 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20694 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20695 This avoids undefined behavior on integer overflow, and is a bit
20696 more convenient anyway since it is compared to a size_t variable.
20698 Variadic C functions now count arguments with size_t, not int.
20699 This avoids an unnecessary limitation on 64-bit machines, which
20700 caused (substring ...) to crash on large vectors (Bug#8344).

20710 * fns.c (concat): Likewise.
20711 * frame.c (x_set_frame_parameters): Likewise.
20712 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20713 0 if not found, not -1. All callers changed.
20715 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20716 (stack_copy_size): Now size_t, not int.
20717 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

20738 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20739 don't set the hook to nil, but remove the offending function instead.

20741 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20742 Vcommand_hook_internal.

20745 (funcall_nil, funcall_not): New functions.
20746 (run_hook_with_args): Call each function through a `funcall' argument.

20881 Remove unused variable `width'.
20883 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
20885 * w32term.c (x_set_glyph_string_clipping):
20886 Don't pass uninitialized region to CombineRgn.
20888 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
20890 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

20910 2011-03-23 Julien Danjou <julien@danjou.info>
20912 * term.c (Fsuspend_tty, Fresume_tty):
20913 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
20914 * window.c (temp_output_buffer_show):
20915 * insdel.c (signal_before_change):
20916 * frame.c (Fhandle_switch_frame):
20917 * fileio.c (Fdo_auto_save):

20920 * cmds.c (internal_self_insert):
20921 * callint.c (Fcall_interactively):
20922 * buffer.c (Fkill_all_local_variables):
20923 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20925 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20926 unconditionally since it does the check itself.
20928 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20930 Fix more problems found by GCC 4.5.2's static checks.
20932 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20933 the first time through the loop, since we know p0 < p1 then.
20934 This also avoids a gcc -Wstrict-overflow warning.
20936 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20937 leading to a memory leak, possible in functions like
20938 load_charset_map_from_file that can allocate an unbounded number
20939 of objects (Bug#8318).
20941 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20942 that could (at least in theory) be that large.
20944 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20945 This is less likely to overflow, and avoids undefined behavior if
20946 overflow does occur. All callers changed. Use strtoul to scan
20947 for the unsigned long integer.
20948 (pint2hrstr): Simplify and tune code slightly.
20949 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
20951 * scroll.c (do_scrolling): Work around GCC bug 48228.
20952 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
20954 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
20955 This also avoids a warning with gcc -Wstrict-overflow.
20956 (validate_x_resource_name): Simplify count usage.
20957 This also avoids a warning with gcc -Wstrict-overflow.
20959 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20962 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20964 * process.c (Fmake_network_process): Use socklen_t, not int,
20965 where POSIX says socklen_t is required in portable programs.
20966 This fixes a porting bug on hosts like 64-bit HP-UX, where
20967 socklen_t is wider than int (Bug#8277).
20968 (Fmake_network_process, server_accept_connection):
20969 (wait_reading_process_output, read_process_output):
20972 * process.c: Rename or move locals to avoid shadowing.

20982 Make tparam.h and terminfo.c consistent.
20983 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20984 Include tparam.h instead, since it declares them.
20985 * cm.h (PC): Remove extern decl; tparam.h now does this.
20986 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20987 * terminfo.c: Include tparam.h, to check interfaces.
20988 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20989 (tparam): Adjust signature to match interface in tparam.h;
20990 this removes some undefined behavior. Check that outstring and len
20991 are zero, which they always are with Emacs.
20992 * tparam.h (PC, BC, UP): New extern decls.
20994 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20995 (xftfont_open): Rename locals to avoid shadowing.
20997 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
20998 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
20999 (OTF_TAG_SYM): Omit macro if not needed.

21007 * xml.c (make_dom): Now static.
21009 * composite.c (composition_compute_stop_pos): Rename local to
21011 (composition_reseat_it): Remove unused locals.
21012 (find_automatic_composition, composition_adjust_point): Likewise.
21013 (composition_update_it): Mark var as initialized.
21014 (find_automatic_composition): Mark vars as initialized,
21015 with a FIXME (Bug#8290).

21018 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
21019 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21020 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21021 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21022 to avoid shadowing.
21024 * textprop.c (property_change_between_p): Remove; unused.
21026 * intervals.c (interval_start_pos): Now static.
21028 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

21031 Rename locals to avoid shadowing.
21033 * sound.c (wav_play, au_play, Fplay_sound_internal):
21034 Fix pointer signedness.
21035 (alsa_choose_format): Remove unused local var.
21036 (wav_play): Initialize a variable to 0, to prevent undefined
21037 behavior (Bug#8278).
21039 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21041 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21043 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21044 clobbering (Bug#8298).
21045 * sysdep.c (sys_subshell): Likewise.
21046 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21048 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21049 This should get cleaned up, so that child_setup has the
21050 same signature on all platforms.
21052 * callproc.c (call_process_cleanup): Now static.
21053 (relocate_fd): Rename locals to avoid shadowing.
21055 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21057 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21058 not to be necessary, and produces flickering.
21060 2011-03-20 Glenn Morris <rgm@gnu.org>
21062 * config.in: Remove file.
21064 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
21066 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
21067 are now in src/globals.h.
21068 (syms_of_minibuf): Remove spurious & from previous change.
21070 2011-03-20 Leo Liu <sdl.web@gmail.com>
21072 * minibuf.c (completing-read-function): New variable.
21073 (completing-read-default): Rename from completing-read.
21074 (completing-read): Call completing-read-function.
21076 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
21078 * xfaces.c (Fx_load_color_file):
21079 Read color file from absolute filename (bug#8250).
21081 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
21083 * makefile.w32-in: Update dependencies.
21085 2011-03-17 Eli Zaretskii <eliz@gnu.org>
21087 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

21094 (sigchld_handler): Now static.
21096 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
21097 That way, the code declares only the vars that it needs.
21098 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
21099 * s/cygwin.h (PTY_ITERATION): Likewise.
21100 * s/darwin.h (PTY_ITERATION): Likewise.

21106 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
21107 (CONSTANTLIM): Remove; unused.
21108 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
21109 Define only if needed.
21111 * unexelf.c (unexec): Name an expression,
21112 to avoid gcc -Wbad-function-cast warning.
21113 Use a different way to cause a compilation error if anyone uses
21114 n rather than nn, a way that does not involve shadowing.
21115 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21117 * deps.mk (unexalpha.o): Remove; unused.
21119 New file unexec.h, the (simple) interface for unexec (Bug#8267).
21120 * unexec.h: New file.
21121 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
21122 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
21123 Depend on unexec.h.
21124 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
21125 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
21126 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
21127 Change as necessary to match prototype in unexec.h.
21129 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
21131 (back_comment, skip_chars): Mark vars as initialized.

21145 instead of using an uninitialized var.
21146 (font_sort_entities): Mark var as initialized.
21148 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
21150 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

21162 * floatfns.c (domain_error2): Define only if needed.
21163 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
21165 * alloc.c (mark_backtrace): Move decl from here ...
21166 * lisp.h: ... to here, so that it can be checked.
21168 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
21169 (Fdefvar): Rewrite so as not to use empty "else".

21174 * callint.c (quotify_arg, quotify_args): Now static.
21175 (Fcall_interactively): Rename locals to avoid shadowing.
21176 Use const pointer when appropriate.
21178 * lisp.h (get_system_name, get_operating_system_release):

21182 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
21183 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
21184 some of which prompt warnings from gcc -Wbad-function-cast.
21185 (Fformat_time_string, Fencode_time, Finsert_char):
21186 (Ftranslate_region_internal, Fformat):
21187 Rename or remove local vars to avoid shadowing.
21188 (Ftranslate_region_internal): Mark var as initialized.
21190 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
21193 * lisp.h (eassert): Check that the argument compiles, even if
21194 ENABLE_CHECKING is not defined.
21196 * data.c (Findirect_variable): Name an expression, to avoid
21197 gcc -Wbad-function-cast warning.

21205 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
21206 Rename locals to avoid shadowing.
21207 (mark_stack): Move local variables into the #ifdef region where
21209 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
21210 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
21212 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
21213 (GC_STRING_CHARS): Remove; not used.
21214 (Fmemory_limit): Cast sbrk's returned value to char *.
21216 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
21217 avoids undefined behavior in theory.
21219 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
21221 Use functions, not macros, for up- and down-casing (Bug#8254).
21222 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21223 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21224 to use the following functions instead of these macros.
21225 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21226 EMACS_INT, since callers assume the returned value fits in int.
21227 (upcase1): Likewise, for UPCASE_TABLE.
21228 (uppercasep, lowercasep, upcase): New static inline functions.
21229 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
21230 the race-condition problem in the old DOWNCASE.
21232 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
21233 Rename locals to avoid shadowing.
21234 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
21235 (regex_compile, re_search_2, re_match_2_internal):
21236 Remove unused local vars.
21237 (FREE_VAR): Rewrite so as not to use empty "else",
21238 which gcc can warn about.
21239 (regex_compile, re_match_2_internal): Mark locals as initialized.
21240 (RETALLOC_IF): Define only if needed.
21241 (WORDCHAR_P): Likewise. This one is never needed, but is used
21242 only in a comment talking about a compiler bug, so put inside
21243 the #if 0 of that comment.
21244 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21245 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
21248 * search.c (boyer_moore): Rename locals to avoid shadowing.
21249 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
21250 (PREV_CHAR_BOUNDARY): Likewise.
21252 * search.c (simple_search): Remove unused var.
21254 * dired.c (compile_pattern): Move decl from here ...

21260 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
21262 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
21263 Rename locals to avoid shadowing.
21264 (Fvertical_motion): Mark locals as initialized.
21266 * casefiddle.c (casify_object, casify_region): Now static.
21267 (casify_region): Mark local as initialized.
21269 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
21271 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21272 New macros, so that the caller can use some names other than
21273 gcpro1, gcpro2, etc.
21274 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21276 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21277 argument, for consistency with GCPRO2_VAR, etc: it is now the
21278 prefix of the variable, not the variable itself. All uses
21280 * dired.c (directory_files_internal, file_name_completion):
21281 Rename locals to avoid shadowing.
21283 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21284 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21285 dired.c's scmp function, had undefined behavior.
21286 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21287 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21288 * buffer.h: ... to here, because these macros use current_buffer,
21289 and the new implementation with inline functions needs to have
21290 current_buffer in scope now, rather than later when the macros
21292 (downcase, upcase1): New static inline functions.
21293 (DOWNCASE, UPCASE1): Reimplement using these functions.
21294 This avoids undefined behavior in expressions like
21295 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21296 from race conditions in accessing the global variables
21297 case_temp1 and case_temp2.
21298 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
21299 * lisp.h (case_temp1, case_temp2): Remove their decls.
21300 * character.h (ASCII_CHAR_P): Move from here ...
21301 * lisp.h: ... to here, so that the inline functions mentioned
21302 above can use them.
21304 * dired.c (directory_files_internal_unwind): Now static.
21306 * fileio.c (file_name_as_directory, directory_file_name):
21307 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
21309 (file_name_as_directory): Use const pointers when appropriate.
21310 (Fexpand_file_name): Likewise. In particular, newdir might
21311 point at constant storage, so make it a const pointer.
21312 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
21313 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
21315 (Fset_file_times, Finsert_file_contents, auto_save_error):
21316 Rename locals to avoid shadowing.
21318 * minibuf.c (choose_minibuf_frame_1): Now static.
21319 (Ftry_completion, Fall_completions): Rename or remove locals
21320 to avoid shadowing.
21322 * marker.c (bytepos_to_charpos): Remove; unused.

21746 is actually in tparam.c. The previous trick of using incompatible
21747 decls in different modules does not conform to the C standard.
21748 All callers of tparam changed to use tparam's actual API.
21749 * tparam.c (tparam1, tparam, tgoto):
21750 Use const pointers where appropriate.

21759 * termchar.h (struct tty_display_info): Likewise.
21761 * term.c (term_mouse_position): Rename local to avoid shadowing.
21763 * alloc.c (mark_ttys): Move decl from here ...
21764 * lisp.h (mark_ttys): ... to here, so that it's checked against defn.
