3 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
4 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
5 * dired.c: Include <fcntl.h>.
6 (open_directory): New function, which uses open and fdopendir
7 rather than opendir. DOS_NT platforms still use opendir, though.
8 (directory_files_internal, file_name_completion): Use it.
9 (file_attributes): New function, with most of the old Ffile_attributes.
10 (directory_files_internal, Ffile_attributes): Use it.
11 (file_attributes, file_name_completion_stat): First arg is now fd,
12 not dir name. All uses changed. Use fstatat rather than lstat +
14 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
15 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
16 (emacs_readlinkat): New function, with much of the old
17 Ffile_symlink_p, but with an fd argument for speed.
18 It uses readlinkat rather than careadlinkatcwd, so that it
19 need not assume the working directory.
20 (Ffile_symlink_p): Use it.
21 * filelock.c (current_lock_owner): Use emacs_readlinkat
22 rather than emacs_readlink.
23 * lisp.h (emacs_readlinkat): New decl.
24 (READLINK_BUFSIZE, emacs_readlink): Remove.
25 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
26 (emacs_norealloc_allocator, emacs_readlink): Remove.
27 This stuff is moved to fileio.c.
28 * w32.c (fstatat, readlinkat): New functions.
29 (careadlinkat): Don't check that fd == AT_FDCWD.
30 (careadlinkatcwd): Remove; no longer needed.
32 2013-01-31 Glenn Morris <rgm@gnu.org>
34 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
35 (Fwrite_region): Update for new choose_write_coding_system args.
36 Move the last piece of choose_write_coding_system here. (Bug#13522)
37 (syms_of_fileio): Add choose-write-coding-system.
39 2013-01-30 Eli Zaretskii <eliz@gnu.org>
41 * w32.c (sys_open): Zero out the flags for the new file descriptor.
42 (sys_close): Zero out the flags for the file descriptor before
43 closing it. (Bug#13546)
45 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
46 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
47 CharNextExA and CharPrevExA to iterate over file names encoded in
50 * w32.c (w32_get_long_filename, init_environment, readlink):
51 Support file names encoded in DBCS codepages.
52 (readlink): Use the current file-name-coding-system, not the ANSI
53 codepage, to decode and handle targets of symlinks.
55 2013-01-28 Eli Zaretskii <eliz@gnu.org>
57 * w32.c (opendir): Now accepts a 'const char *'.
59 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
61 Remove obsolete redisplay code. See the discussion at
62 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
63 * dispnew.c (preemption_period, preemption_next_check): Remove.
64 (Vredisplay_preemption_period): Likewise.
65 (update_frame, update_single_window, update_window, update_frame_1):
66 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
67 used, following the 2012-06-22 change.
69 2013-01-25 Eli Zaretskii <eliz@gnu.org>
71 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
73 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
75 * font.c (num_fonts): Remove the leftover from old
76 debugging code. Adjust comment style here and there.

78 * lisp.h (insert_1): Remove prototype.
79 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
81 2013-01-25 Eli Zaretskii <eliz@gnu.org>
83 * w32.c (max_filename_mbslen): New function.
84 (normalize_filename, readdir): Use it to detect locales where ANSI
85 encoding of file names uses a double-byte character set (DBCS).
86 If a DBCS encoding is used, advance by characters using
87 CharNextExA, instead of incrementing a 'char *' pointer. Use
88 _mbslwr instead of _strlwr. (Bug#13515)
90 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
91 request of memory reservation to 1.7GB. (Bug#13065)
93 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
95 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
96 at check_extra_latin label. (Bug#13505)
98 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
100 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
101 Avoid redundant calls to strlen.
103 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
105 Drop async_visible and async_iconified fields of struct frame.
106 This is possible because async input is gone; for details, see
107 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
108 * frame.h (struct frame): Remove async_visible and async_iconified
109 members, convert garbaged to unsigned bitfield. Adjust comments.
110 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
111 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
112 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
113 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
114 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
116 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
117 properly. Likewise for obscured.
119 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
122 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
124 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
126 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
127 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
129 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
131 * xdisp.c (message2, message2_nolog): Remove functions.
132 (message3, message3_nolog): Extract nbytes and multibyteness directly
133 from the string. Change all callers.
134 (message3_nolog): Don't set message_enable_multibyte since set_message
135 will reset it anyway.
136 (message1, message1_nolog): Use message3.
137 (vmessage): Use a stack allocated buffer rather than f->message_buf.
138 (with_echo_area_buffer): Remove last two arguments. Update all callers.
139 (set_message): Drop all but the second arg, which has to be a string.
140 (set_message_1): Simplify now that we know that a1 is NULL and the
141 second arg is a string.
142 * frame.h (struct frame): Remove `message_buf' field.
143 Use glyphs_initialized_p instead.
144 (FRAME_MESSAGE_BUF): Remove macro.

148 * keyboard.c (read_char_minibuf_menu_text)
149 (read_char_minibuf_menu_width): Remove vars.
150 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
151 to correctly handle multibyte strings.
152 * frame.c (delete_frame): Don't free message_buf any more.
153 * editfns.c (message_text, message_length): Remove vars.
154 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
155 * fileio.c (auto_save_error): Use message3 instead of message2.
156 * dispnew.c (adjust_frame_message_buffer): Remove function.
158 2013-01-23 Eli Zaretskii <eliz@gnu.org>

165 * insdel.c (prepare_to_modify_buffer): Force redisplay if
166 hidden buffer is prepared to modification (Bug#13164).
168 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
170 * window.h (struct window): Change window_end_valid member from
171 Lisp_Object to a bitfield. Adjust comments.
172 (wset_window_end_valid): Remove.
173 * window.c (adjust_window_count): Clear window_end_valid.
174 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
175 (Fwindow_line_height, set_window_buffer, Frecenter)
176 (Fsplit_window_internal, Fdelete_other_windows_internal)
177 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
178 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
179 * xdisp.c (check_window_end, reconsider_clip_changes)
180 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
181 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
182 (find_first_unchanged_at_end_row, try_window_id): Likewise.
184 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
186 * xdisp.c (mark_window_display_accurate): Simplify the loop
187 assuming that the only one of vchild, hchild or buffer window
188 slots is non-nil. Call mark_window_display_accurate_1 for
189 the leaf windows only.
190 (mark_window_display_accurate_1): Always assume leaf window.
193 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
195 * emacs.c (Qkill_emacs_hook): Now static.
197 * fileio.c (Finsert_file_contents): Simplify.
198 Remove unnecessary assignments and tests.
200 2013-01-21 Eli Zaretskii <eliz@gnu.org>
202 * w32.c (acl_set_file): Don't test for errors unless
203 set_file_security returns FALSE. Avoids spurious errors when
206 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
208 * fileio.c (Finsert_file_contents): Revert code introduced at
209 2013-01-18 in favor of the simpler and generally better fix.
210 Save stack space by removing 'buffer' and reusing 'read_buf'
213 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
215 * lisp.h (eabs): Define unconditionally (Bug#13419).
216 The old "#if !defined (eabs)" was an unnecessary revenant of back
217 when this macro was called "abs". Document 'eabs' better.
219 2013-01-19 Glenn Morris <rgm@gnu.org>
221 * fns.c (Frandom): Doc fix.
223 2013-01-19 Eli Zaretskii <eliz@gnu.org>
225 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
226 segfault when there are lots of overlays.
228 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
229 when there are lots of overlays. See
230 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
231 for the details and a way to reproduce.
233 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
235 * fileio.c: Use O_APPEND to append.
236 This corresponds better to the natural interpretation of "append",
237 and avoids the need to open the output file twice, or to invoke
238 lseek when APPEND is neither nil nor a number.
239 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
240 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
241 file possibly twice, and lseeking to its end; this avoids the
242 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
243 at the same time: the combination is never needed and apparently
244 it doesn't work with DOS_NT.
246 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
247 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
249 Allow floating-point file offsets.
250 Problem reported by Vitalie Spinu in
251 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
252 * fileio.c (emacs_lseek): Remove.
253 (file_offset): New function.
254 (Finsert_file_contents, Fwrite_region): Use it.
256 2013-01-19 Chong Yidong <cyd@gnu.org>
258 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
259 aborting on Fsignal (Bug#13289).
261 2013-01-19 Eli Zaretskii <eliz@gnu.org>
263 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
264 set_file_security as failure due to insufficient privileges.
265 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
266 (fstat): Return owner and group like 'stat' and 'lstat' do.
268 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
270 Work around bug in CIFS and vboxsf file systems (Bug#13149).
271 The bug was observed on Ubuntu operating inside a virtual machine,
272 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
273 The workaround introduces a race condition on non-buggy hosts,
274 but it's an unlikely race and anyway there's a nearly identical
275 nearby race that can't be fixed.
276 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
278 (Fwrite_region): Test for file system time stamp bug.
279 (init_fileio): New function.
280 * lisp.h (init_fileio): Declare it.
281 * emacs.c (main): Call it.
283 * fileio.c (Finsert_file_contents): Simplify new diagnostic
284 and make it more consistent with other stat-failure diagnostics.
286 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
288 Fix crash when inserting data from non-regular files. See
289 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
290 for the error description produced by valgrind.
291 * fileio.c (read_non_regular): Rename to read_contents.
292 Free Lisp_Save_Value object used to pass parameters.
293 (read_non_regular_quit): Rename to read_contents_quit.
294 (Finsert_file_contents): Redesign internal file reading loop to adjust
295 gap and end positions after each read and so help make_gap to work
296 properly. Do not signal an I/O error too early and so do not leave
297 not yet decoded characters in a buffer, which was the reason of
298 redisplay crash. Use list2 to build return value. Adjust comments.
300 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
302 Close a race when statting and reading files (Bug#13149).
303 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
304 This avoids a race if the file is renamed between stat and open.
305 This race is not the problem originally noted in Bug#13149;
306 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
308 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

316 * alloc.c (format_save_value): Rename to make_save_value.
317 (make_save_pointer): New function.
318 (record_xmalloc): Use make_save_pointer.
319 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
320 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
321 Change users of make_save_value to make_save_pointer.
322 Likewise for format_save_value and make_save_value.
324 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

338 (map_keymap_char_table_item): Adjust accordingly.
339 * fileio.c (non_regular_fd, non_regular_inserted)
340 (non_regular_nbytes): Remove.
341 (Finsert_file_contents): Convert trytry to ptrdiff_t. Use
342 format_save_value to pass parameters to read_non_regular.
343 (read_non_regular): Use XSAVE_ macros to extract parameters.
345 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
347 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
349 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
351 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
352 extraction from any Lisp_Save_Value slot. Add type checking.
353 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
354 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
355 * xselect.c: All users changed.
357 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
359 Some convenient bits to deal with Lisp_Save_Values.

374 * dired.c (directory_files_internal_unwind):
375 * fileio.c (do_auto_save_unwind):
376 * gtkutil.c (pop_down_dialog):
377 * keymap.c (map_keymap_char_table_item):
378 * lread.c (load_unwind):
379 * nsmenu.m (pop_down_menu):
380 * print.c (print_object) [GC_MARK_STACK]:
381 * xfns.c (clean_up_file_dialog):
382 * xmenu.c (cleanup_widget_value_tree):
383 Omit casts between XSAVE_POINTER and a pointer type.
385 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
387 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
388 * eval.c (eval_sub): Protect `form' from being GCed before its
389 car and cdr becomes protected with the backtrace entry.

401 (free_misc): Likewise. Adjust comment.
402 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
403 (free_save_value): Likewise.
404 (mark_object): Likewise.
405 * editfns.c (save_excursion_save): Pack everything within
406 Lisp_Save_Value and so avoid xmalloc.
407 (save_excursion_restore): Adjust to match new layout. Use free_misc
408 because we do not allocate extra memory any more. Add eassert.
409 * print.c (print_object): New code to print Lisp_Save_Value. Do not
410 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
411 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
412 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:
413 Use XSAVE_POINTER and XSAVE_INTEGER where appropriate.

482 anyway, all of them should use move_gap_both instead.
483 * lisp.h (move_gap): Remove prototype.
484 * insdel.c (move_gap): Remove.
485 (move_gap_both): Add eassert.
486 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.

491 emacsclient -t should not suspend Emacs server (Bug#13387)
492 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
494 * term.c (init_tty): Use them instead of rolling our own code.
495 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
496 switches from 'signal' to 'pthread_sigmask', which is safer in
497 multithreaded applications.
498 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
499 which has already arranged for that.
500 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
501 This is the main part of the bug fix.

514 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
515 * buffer.c (buffer_slot_type_mismatch): Remove.
516 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
517 predicate. Adjust comment.

521 right-fringe-width, scroll-bar-width and buffer-display-count.
522 Use Qstringp for default-directory, buffer-file-name,
523 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
524 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
526 * data.c (store_symval_forwarding): Adjust to call the predicate.
528 2013-01-09 Juanma Barranquero <lekktu@gmail.com>

543 (make_gap_1): New function to adjust the gap of any buffer.
544 * coding.c (coding_alloc_by_making_gap): Use it.
545 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
546 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
548 2013-01-08 Juri Linkov <juri@jurta.org>
550 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
551 of (supports :underline (:style wave)). (Bug#13000)

569 trailing dash is properly added.
571 2013-01-05 Eli Zaretskii <eliz@gnu.org>
573 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
574 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
575 digits for buffer positions, before misalignment starts.
576 Display "0" for integer "object" field.
577 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
578 Display the newline glyph more unambiguously.
580 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
582 * nsterm.m (ns_draw_underwave):
583 * w32term.c (w32_draw_underwave):
584 * xterm.c (x_draw_underwave): Make underwave look more triangular
585 and also degrade gracefully for small fonts. (Bug#13000)
587 * nsterm.m (ns_draw_text_decoration):
588 * w32term.c (x_draw_glyph_string):
589 * xterm.c (x_draw_glyph_string): Don't use previous underline
590 thickness and position if previous underline type is underwave.
592 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
594 * fileio.c (Ffile_acl): Undocument return format.
596 2013-01-02 Glenn Morris <rgm@gnu.org>
598 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
600 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>
603 * dired.c (file_name_completion):
604 * doc.c (get_doc_string):

609 * minibuf.c (Ftry_completion):
610 * term.c (tty_ins_del_lines):
611 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
612 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
614 2012-12-31 Eli Zaretskii <eliz@gnu.org>
616 * w32.c (unsetenv): Set up the string passed to _putenv
618 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
619 for the bug this caused.
621 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
623 * coding.c (Qmac): Now static.
625 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
627 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
628 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
629 handlebox_widget. Set toolbar_in_hbox to false/true, set
630 toolbar_is_packed to true.
631 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
632 (update_frame_tool_bar): Check toolbar_is_packed for packing.
633 Show all on TOOLBAR_TOP_WIDGET.
634 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned

636 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
637 Check toolbar_is_packed.
638 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
639 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
640 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
642 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
643 (xg_update_menubar): Update title only if
644 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
645 (xg_update_submenu): Skip tearoff only if
646 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
647 (xg_initialize): Initialize xg_detached_menus only if
648 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
650 * xterm.h (struct x_output): Surround handlebox_widget with
651 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,

654 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
656 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
657 (LIBS_GNUSTEP): Define.
658 (LIBES): Add $(LIBS_GNUSTEP).

661 2012-12-30 Eli Zaretskii <eliz@gnu.org>
663 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
664 continuation glyph on a TTY with an indication of an empty line.
667 2012-12-29 Eli Zaretskii <eliz@gnu.org>
669 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
670 file's SELinux context or ACLs successfully set, nil otherwise.
672 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
674 * w32proc.c (reader_thread): Avoid passing NULL handles to
675 SetEvent and WaitForSingleObject.
677 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
679 Port EXTERNALLY_VISIBLE to Clang 3.2.
680 * conf_post.h (__has_attribute): New macro.
681 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
683 2012-12-27 Glenn Morris <rgm@gnu.org>
685 * cygw32.c (Fcygwin_convert_file_name_to_windows)
686 (Fcygwin_convert_file_name_from_windows): Doc fixes.
688 2012-12-27 Eli Zaretskii <eliz@gnu.org>
690 * fileio.c (file_name_as_directory, directory_file_name):
691 Accept an additional argument MULTIBYTE to indicate whether the input C
692 came from a multibyte or a unibyte Lisp string; all callers
693 adjusted. Don't assume the input string is always multibyte.
695 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
696 don't ENCODE_FILE them, and return a unibyte string if the input
698 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
699 don't assume the input strings will always be multibyte. If the
700 input strings are multibyte, decode strings obtained from C

705 * lisp.h (toplevel): Add two notices to the comment about
706 defining a new Lisp data type.
707 * print.c (print_object): If Lisp_Save_Value object's pointer
708 is the address of a memory area containing Lisp_Objects, try
710 * alloc.c (valid_lisp_object_p): Adjust comment.
712 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
714 * keyboard.c (record_asynch_buffer_change): Initialize an event
715 only if it's really needed.
716 * frame.h (enum output_method): Remove output_mac member since
717 it's a leftover from the deleted code.
718 * frame.c (Fframep): Adjust user here ...
719 * terminal.c (Fterminal_live_p): ... and here.
720 * coding.c (Qmac): Now here because it's only used to denote
721 end-of-line encoding type.
722 (syms_of_coding): DEFSYM it.
723 * frame.h (Qmac): Remove duplicated declaration.
725 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
727 * window.c (select_window_1): Now static, since it's used only here.
729 2012-12-25 Eli Zaretskii <eliz@gnu.org>
731 * window.c (window_body_cols): Subtract display margins from the
732 window body width on TTYs as well. See
733 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
734 for the original report.
736 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
738 * xdisp.c (redisplay_window): Remove inner local variable
739 because the outer shadowed one has the same meaning.
740 * xterm.h (struct x_output): Remove toolbar_detached member since it's
742 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
743 (xg_create_tool_bar): Adjust users.
745 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
747 * buffer.h (BUF_COMPACT): New macro to follow the common style.
748 * buffer.c (Fget_buffer_create): Use it to set compact field of
749 struct buffer_text to avoid accessing an uninitialized value
750 when compact_buffer is called for the first time.
751 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
752 (Fset_buffer_modified_p): Use buffer_window_count to check
753 whether the buffer is displayed in some window.
754 * xdisp.c (message_dolog): Likewise.
756 2012-12-23 Eli Zaretskii <eliz@gnu.org>
758 * w32.c (acl_set_file): If setting the file security descriptor
759 fails, and the new DACL is identical to the existing one, silently
760 return success. This fixes problems for users backing up their
761 own files without having the necessary privileges for setting
762 security descriptors.
764 * w32proc.c (reader_thread): Do not index fd_info[] with negative
766 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
767 after WaitForSingleObject returns normally. This expedites reader
768 thread shutdown when delete_child triggers it.
769 (reap_subprocess): More accurate commentary for why we call
770 delete_child only when cp->fd is negative.
772 * w32.c (sys_close): Do not call delete_child on a subprocess
773 whose handle is not yet closed. Instead, set its file descriptor
774 to a negative value, so that reap_subprocess will call
775 delete_child on that subprocess when its SIGCHLD arrives.
776 This avoids closing handles used for communications between sys_select
777 and reader_thread, which doesn't give sys_select a chance to
778 notice that the process exited and invoke the SIGCHLD handler for
781 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
783 * nsfns.m (Fns_do_applescript): Run event loop until script has
784 been executed (Bug#12969).
785 (ns_run_ascript): Chech as_script for nil, set to nil after
788 2012-12-22 Martin Rudalics <rudalics@gmx.at>
790 * window.c (Fselect_window): Reword doc-string (Bug#13248).

794 * w32term.c (w32fullscreen_hook): New function.
795 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
797 2012-12-21 Eli Zaretskii <eliz@gnu.org>
799 * fileio.c (Finsert_file_contents): Doc fix.
801 * w32proc.c (new_child, delete_child, find_child_pid): For a
802 subprocess, consider its slot being in use as long as its process
803 handle (procinfo.hProcess) is not NULL. This avoids reusing the
804 slot when a new process is started immediately after killing
805 another one, without waiting enough time for the first process to
806 be reaped and resources allocated for it be orderly freed.
808 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
810 2012-12-21 Chong Yidong <cyd@gnu.org>
812 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
814 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
816 2012-12-21 Eli Zaretskii <eliz@gnu.org>
818 * w32.c (get_name_and_id): Always pass NULL as the first argument
819 of lookup_account_sid. Avoids crashes with UNC file names that
820 refer to DFS domains, not to specific machine names. (Bug#12621)
821 Remove now unused argument FNAME; all callers changed.
822 (get_file_owner_and_group): Remove now unused argument FNAME; all
825 2012-12-21 Chong Yidong <cyd@gnu.org>
827 * editfns.c (Finsert_char): Since read-char-by-name now signals an
828 error for invalid chars, don't check for a nil return value.
830 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
832 Avoid calls to CHAR_TO_BYTE if byte position is known.
833 * editfns.c (make_buffer_string_both): Use move_gap_both.
834 (Fbuffer_string): Use make_buffer_string_both.
835 * marker.c (buf_charpos_to_bytepos): Convert to eassert.

839 * fileio.c (Finsert_file_contents): Use move_gap_both.
840 * search.c (Freplace_match): Likewise.
841 * process.c (process_send_region): Likewise. Use convenient
842 names for byte positions.
843 * lisp.h (charpos_to_bytepos): Remove prototype.
844 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
845 * insdel.c (move_gap): Likewise.

854 (redisplay_internal): Don't bother selecting the frame to get the
855 proper value of frame-local variables (bug#13225).
857 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
859 * textprop.c (set_text_properties_1): Do not allow NULL interval.
860 Rename 4th argument since it may be buffer or string. Adjust comment.
861 * intervals.c (graft_intervals_info_buffer): Find an interval here.
863 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
865 * coding.c (Fdetect_coding_region): Do not check start and end with
866 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
867 (code_convert_region): Likewise.
869 2012-12-18 Eli Zaretskii <eliz@gnu.org>
871 * w32.c (acl_get_file, acl_set_file): Run the file name through
872 map_w32_filename, and resolve any symlinks in the file name, like
874 (acl_set_file): Call revert_to_self, if any privileges were

880 ($(BLD)/w32.$(O)): Update dependencies.
882 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
884 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
885 propagate redisplay's scrolling (if any) to the right window.
886 (redisplay_internal): Use ensure_selected_frame.
887 (display_mode_lines): Complete last fix.
888 * window.c (select_window_1): New func, extracted from select_window.
889 (select_window): Use it.
890 * window.h (select_window_1): Declare.

918 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
919 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
920 for some of that bug's symptoms can now cause Emacs to abort.
921 Remove the workaround.
922 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
923 The bug that caused SIGCHLD to get lost has been fixed, and the

963 * fileio.c (internal_delete_file): Return an int again: non-zero
964 if delete-file succeeds, zero otherwise.
966 * lisp.h (internal_delete_file): Adjust prototype.
968 * callproc.c (Fcall_process): Don't overwrite infile with result
970 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an

973 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
974 delete the file, record it as pending deletion when the subprocess

985 Fix permissions bugs with setgid directories etc. (Bug#13125)
986 * dired.c (Ffile_attributes): Return t as the 9th attribute,
987 to mark it as a placeholder. The old value was often wrong.

989 file-ownership-preserved-p instead, with its new group arg.
990 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.

999 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1000 try to get accurate owner and group information from NT file
1001 security APIs. This is to make most callers of 'stat' and
1002 'lstat', which don't need that information, much faster.
1004 * dired.c (Ffile_attributes) [WINDOWSNT]:
1005 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1006 owner and group information from 'lstat'.
1008 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1010 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1011 as that confuses set-auto-coding, so insist on the head-read
1012 returning the full 1024 bytes. Let lseek compute the tail offset;
1013 less work for us. Do not ignore I/O errors when reading the tail.
1015 * xdisp.c: Minor style fixes.
1016 (init_iterator): Hoist assignment out of if-expression.
1017 (markpos_of_region): Callers now test for sign, not for -1.

1036 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1037 files, fixing a regression from 24.2.
1038 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1040 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1042 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1043 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1044 Remove unnecessary S_ISLNK test, as (contra the comments) this
1045 function can't copy symlinks. Improve quality of error message
1046 when attempting to copy files that are neither regular files nor

1065 * inotify.c (inotify_callback): Generate an Emacs event for every
1066 incoming inotify event.

1070 * xdisp.c (handle_face_prop): Fix logic of computing
1071 it->start_of_box_run_p.

1078 left_box_line_p and right_box_line_p flags of the glyph for R2L
1079 glyph rows. (Bug#13011)

1094 encoded_file_name, which is what it is.
1096 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

1126 variable here so various initialization calls DTRT.
1128 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1129 (hinst): Remove unneeded extern declaration.
1130 (_start): Remove initialization of above variables; remove

1350 * frame.c (make_frame): Do not set window's buffer to t.
1351 * window.c (Fsplit_window_internal): Likewise. Previously it was

1388 (call_process_kill): Use it.
1389 This does not change call_process_kill's behavior.
1390 * process.c (Fdelete_process): Use record_kill_process to fix a
1391 race condition that could cause Emacs to lose track of a child.

1402 fails, signal an error instead of continuing with an empty
1404 Encode expanded temp file pattern before passing it to mkstemp or
1407 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1408 Encode the file name before passing it to dostounix_filename, in
1409 case it will downcase it (under w32-downcase-file-names).
1412 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1414 Minor call-process cleanups.
1415 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1416 at the same time as other platforms, to simplify analysis.
1417 No need for fd0_volatile since we have synch_process_fd.

1440 Don't let call-process be a zombie factory (Bug#12980).
1441 Fixing this bug required some cleanup of the signal-handling code.
1442 As a side effect, this change also fixes a longstanding rare race
1443 condition whereby Emacs could mistakenly kill unrelated processes,
1444 and it fixes a bug where a second C-g does not kill a recalcitrant
1445 synchronous process in GNU/Linux and similar platforms.
1446 The patch should also fix the last vestiges of Bug#9488,
1447 a bug which has mostly been fixed on the trunk by other changes.
1448 * callproc.c, process.h (synch_process_alive, synch_process_death)
1449 (synch_process_termsig, sync_process_retcode):
1450 Remove. All uses removed, to simplify analysis and so that
1451 less consing is done inside critical sections.
1452 * callproc.c (call_process_exited): Remove. All uses replaced
1453 with !synch_process_pid.
1454 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1455 These take the role of what used to be in unwind-protect arg.
1457 (block_child_signal, unblock_child_signal):
1458 New functions, to avoid races that could kill innocent-victim processes.
1459 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1460 (call_process_kill): Record killed processes as deleted, so that
1461 zombies do not clutter up the system. Do this inside a critical
1462 section, to avoid a race that would allow the clutter.
1463 (call_process_cleanup): Fix code so that the second C-g works again
1464 on common platforms such as GNU/Linux.
1465 (Fcall_process): Create the child process in a critical section,
1466 to fix a race condition. If creating an asynchronous process,
1467 record it as deleted so that zombies do not clutter up the system.
1468 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1469 light of these changes. Omit unnecessary call to emacs_close
1470 before failure, as the unwind-protect code does that.
1471 * callproc.c (call_process_cleanup):
1472 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1473 * process.c (record_deleted_pid): New function, containing
1474 code refactored out of Fdelete_process.
1475 (Fdelete_process): Use it.
1476 (process_status_retrieved): Remove. All callers changed to use
1477 child_status_change.
1478 (record_child_status_change): Remove, folding its contents into ...
1479 (handle_child_signal): ... this signal handler. Now, this
1480 function is purely a handler for SIGCHLD, and is not called after
1481 a synchronous waitpid returns; the synchronous code is moved to
1482 wait_for_termination. There is no need to worry about reaping
1483 more than one child now.
1484 * sysdep.c (get_child_status, child_status_changed): New functions.
1485 (wait_for_termination): Now takes int * status and bool
1486 interruptible arguments, too. Do not record child status change;
1487 that's now the caller's responsibility. All callers changed.
1488 Reimplement in terms of get_child_status.
1489 (wait_for_termination_1, interruptible_wait_for_termination):
1490 Remove. All callers changed to use wait_for_termination.
1491 * syswait.h: Include <stdbool.h>, for bool.
1492 (record_child_status_change, interruptible_wait_for_termination):
1494 (record_deleted_pid, child_status_changed): New decls.
1495 (wait_for_termination): Adjust to API changes noted above.
1497 * bytecode.c, lisp.h (Qbytecode): Remove.
1498 No longer needed after 2012-11-20 interactive-p changes.
1500 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1502 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1503 the scroll margin, move point outside the margin. (Bug#13055)
1505 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1507 * gtkutil.c (my_log_handler): New function.
1508 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1510 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1512 * lisp.h (modify_region): Rename to...
1513 (modify_region_1): ...new prototype.
1514 * textprop.c (modify_region): Now static. Adjust users.
1515 * insdel.c (modify_region): Rename to...
1516 (modify_region_1): ...new function to work with current buffer.
1517 Adjust comment and users. Use true and false for booleans.
1519 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1521 * alloc.c (free_save_value): New function.
1522 (safe_alloca_unwind): Use it.
1523 * lisp.h (free_save_value): New prototype.
1524 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1526 (save_excursion_restore): Adjust to match saved data structure.
1527 Use free_save_value to offload some work from GC. Drop obsolete
1530 2012-12-03 Chong Yidong <cyd@gnu.org>
1532 * fileio.c (Vauto_save_list_file_name): Doc fix.
1534 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1536 * w32fns.c: Remove prototype of atof.
1537 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1539 (file_dialog_callback): Make it UINT_PTR.
1541 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1544 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1545 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1548 2012-12-03 Glenn Morris <rgm@gnu.org>
1550 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1552 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1554 Fix xpalloc confusion after memory is exhausted.
1555 * alloc.c (xpalloc): Comment fix.
1556 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1557 and signals an error, do not clear charset_table_size, as
1558 charset_table is still valid.
1559 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1561 Use execve to avoid need to munge environ (Bug#13054).
1562 * callproc.c (Fcall_process):
1563 * process.c (create_process):
1564 Don't save and restore environ; no longer needed.
1565 * callproc.c (child_setup):
1566 Use execve, not execvp, to preserve environ.
1568 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1570 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1572 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1574 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1575 display for sliced images (Bug#10500).
1577 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1579 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1581 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1582 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1584 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1586 * xdisp.c (window_outdated): Remove eassert since it hits
1587 some suspicious corner cases (see Bug#13007 and Bug#13012).
1588 (mode_line_update_needed): New function.
1589 (redisplay_internal, redisplay_window): Use it.

1591 (redisplay_internal, unwind_redisplay): Use it.
1592 (redisplay_internal): Move comment about buffer_shared...
1593 (buffer_shared_and_changed): ...near to its real use.
1595 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1597 * callproc.c (Fcall_process): Don't misreport vfork failure.
1599 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1601 * callproc.c (Fcall_process): Fix vfork portability problems.
1602 Do not assume that fd[0], count, filefd, and save_environ survive
1603 vfork. Fix bug whereby wrong errno value could be reported for
1604 pipe failure. Some minor cleanups, too, as follows. Move buf and
1605 bufsize to the context where they're needed. Change new_argv to
1606 be of type char **, as this is more convenient and avoids casts.
1607 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1608 Now local constants, not macros.
1610 2012-11-18 Kenichi Handa <handa@gnu.org>
1612 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1613 for the variable "f".
1615 2012-11-13 Kenichi Handa <handa@gnu.org>
1617 * font.c (font_unparse_xlfd): Exclude special characters from the
1618 generating XLFD name.
1620 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

1660 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1661 between bpos_covered and bpos_max. This fixes cursor display when
1662 several display strings follow each other.
1664 * .gdbinit (pgx): If the glyph's object is a string, display the
1665 pointer to string data, rather than the value of the string object
1666 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1668 * indent.c (Fvertical_motion): If the starting position is covered
1669 by a display string, return to one position before that, to avoid
1670 overshooting it inside move_it_to. (Bug#12930)
1672 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

1683 Drop unused pending_menu_activation member.
1684 * xterm.h (struct x_output): Drop outdated #if 0 code.
1685 Use bitfields for explicit_parent, asked_for_visible,
1686 has_been_visible and net_wm_state_hidden_seen members.

1690 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1691 of a literal "/". (Bug#12955)
1692 (gl-stamp): Invoke fc.exe directly, not through cmd.

1696 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1697 * dired.c: Assume HAVE_DIRENT_H.
1698 (NAMLEN): Remove, replacing with ...
1699 (dirent_namelen): New function. All uses changed. Use the GNU macro
1700 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1701 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1702 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1703 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1705 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1706 * ndir.h: Rename to ../nt/inc/dirent.h.
1707 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1708 Do not include <dirent.h>; no longer needed.
1709 * w32.c: Include <dirent.h> rather than "ndir.h".
1711 2012-11-23 Chong Yidong <cyd@gnu.org>
1713 * xftfont.c (xftfont_open): Remove duplicate assignment.
1715 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1717 * alloc.c (Fgarbage_collect): Unblock input after clearing
1718 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1719 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1720 * msdos.c (IT_frame_up_to_date): Use it here...
1721 * w32term.c (w32_frame_up_to_date): ...here...
1722 * xterm.c (XTframe_up_to_date): ...and here...
1723 * nsterm.m (ns_frame_up_to_date): ...but not here.
1724 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1726 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1727 Do not check whether GC is in progress.

1735 'tail' and 'frame' local variables.
1737 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1739 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1740 with Windows system header.
1742 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1744 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1745 * alloc.c: Assume unistd.h exists.

1749 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1750 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1751 * w32.h (getcwd): Remove decl.
1753 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>

1762 Cygwin builds, not just GTK builds. See
1763 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1765 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1767 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1768 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1769 Define for the MSVC compiler.
1771 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1773 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1774 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1775 dostounix_filename. Prevents crashes down the road, because
1776 dostounix_filename assumes it gets a unibyte string.
1777 Reported by Michel de Ruiter <michel@sentient.nl>, see
1778 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html

1816 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1817 cygwin_convert_file_name*.
1819 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):

1822 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1824 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1826 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1828 * w32select.c: Include w32common.h before w32term.h, so that
1829 windows.h gets included before w32term.h uses some of its
1830 features, see below.
1832 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1834 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

1843 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1845 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1846 Needed following 2012-10-20 change. (Bug#12902)
1848 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1850 * w32proc.c (waitpid): Remove unused label get_result.
1852 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1854 * makefile.w32-in (SYSWAIT_H): New macro.
1855 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1856 ($(BLD)/sysdep.$(O)): Update dependencies.

1862 * emacs.c, term.c (O_RDWR): Remove.
1863 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1864 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1865 * nsterm.m: Assume <fcntl.h> exists.
1866 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1867 (create_pty, Fmake_network_process, server_accept_connection)
1868 (wait_reading_process_output, init_process_emacs):
1870 (wait_reading_process_output): Put in a special case for WINDOWSNT
1871 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1872 It's not clear this is needed, but it's a more-conservative change.
1873 (create_process): Assume FD_CLOEXEC.
1874 (create_process, create_pty): Assume O_NOCTTY.
1875 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1876 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1877 Omit if not DOS_NT, since F_GETFL is not defined there.
1878 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1879 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1881 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1882 lack it, since gnulib guarantees this.
1883 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1885 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1887 * w32.c (faccessat): Pretend that directories have the execute bit
1888 set. Emacs expects that, e.g., in files.el:cd-absolute.
1890 * w32proc.c (create_child): Don't clip the PID of the child
1891 process to fit into an Emacs integer, as this is no longer a
1893 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1894 reaping only the process specified by PID argument, if that is
1895 positive. Use PID instead of dead_child to know which process to
1896 reap. Wait for the child to die only if WNOHANG is not in
1898 (sys_select): Don't set dead_child.
1900 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1901 as it is no longer needed.
1903 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1905 (record_child_status_change): Remove the setting of
1906 record_at_most_one_child for the !WNOHANG case.
1908 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1910 Fix problems in ns port found by static checking.
1911 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1912 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1913 not to process group.
1914 (ns_select): Use emacs_write, not write, as that's more robust
1915 in the presence of signals.
1916 (fd_handler:): Check for read errors.
1918 2012-11-16 Glenn Morris <rgm@gnu.org>
1920 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1922 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1924 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1926 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1928 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1929 use the same value of thread handle.
1930 (start_timer_thread): If the timer thread exited (due to error),
1931 clean up by closing the two handles it used. Duplicate the caller
1932 thread's handle here, so it gets duplicated only once, when
1933 launching the timer thread. Set priority of the timer thread, not
1935 (getitimer): Don't duplicate the caller thread's handle here.
1938 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1940 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1943 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1945 Remove no-longer-used pty_max_bytes variable.
1946 * process.c (pty_max_bytes): Remove; unused.
1947 (send_process): Do not set it.
1949 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1951 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1952 Update dependencies.
1954 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1956 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1957 This follows up on the 2012-09-29 patch that removed indirection
1958 for the 'function' field. Reported by Sergey Vinokurov in
1959 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1961 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1963 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1964 different name, as the MS runtime does not have such a function,
1965 and probably never will.) All callers changed. Ignore DIRFD
1966 value if PATH is an absolute file name, to match Posix spec
1967 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1970 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1972 * xdisp.c (echo_area_display, redisplay_internal):
1973 Omit redundant check whether frame_garbaged is set.
1975 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1977 Use faccessat, not access, when checking file permissions (Bug#12632).
1978 This fixes a bug that has been present in Emacs since its creation.
1979 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1980 which must set some sort of record. (Torek's bug report was against
1981 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1982 same common flaw.) See Torek's Usenet posting
1983 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1984 Posted: Fri Apr 8 14:18:56 1983.
1985 * Makefile.in (LIB_EACCESS): New macro.
1987 * callproc.c (init_callproc):
1988 * charset.c (init_charset):
1989 * fileio.c (check_existing, check_executable, check_writable)
1991 * lread.c (openp, load_path_check):
1992 * process.c (allocate_pty):
1994 Use effective UID when checking permissions, not real UID.
1995 * callproc.c (init_callproc):
1996 * charset.c (init_charset):
1997 * lread.c (load_path_check, init_lread):
1998 Test whether directories are accessible, not merely whether they exist.
1999 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2000 * fileio.c (check_existing, check_executable, check_writable)
2002 Use symbolic names instead of integers for the flags, as they're
2004 (check_writable): New arg AMODE. All uses changed.
2005 Set errno on failure.
2006 (Ffile_readable_p): Use faccessat, not stat + open + close.
2007 (Ffile_writable_p): No need to call check_existing + check_writable.
2008 Just call check_writable and then look at errno. This saves a syscall.
2009 dir should never be nil; replace an unnecessary runtime check
2010 with an eassert. When checking the parent directory of a nonexistent
2011 file, check that the directory is searchable as well as writable, as
2012 we can't create files in unsearchable directories.
2013 (file_directory_p): New function, which uses 'stat' on most platforms
2014 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2015 (Ffile_directory_p, Fset_file_times): Use it.
2016 (file_accessible_directory_p): New function, which uses a single
2017 syscall for efficiency.
2018 (Ffile_accessible_directory_p): Use it.
2019 * xrdb.c (file_p): Use file_directory_p.
2020 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2021 * lread.c (openp): When opening a file, use fstat rather than
2022 stat, as that avoids a permissions race. When not opening a file,
2023 use file_directory_p rather than stat.
2024 (dir_warning): First arg is now a usage string, not a format.
2025 Use errno. All uses changed.
2026 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2027 that merely introduced a race.
2028 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2029 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2030 and similarly for the other O_* flags.
2031 * w32.c (sys_faccessat): Rename from sys_access and switch to
2032 faccessat's API. All uses changed.
2033 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2034 (magic_db): Rename from magic_file_p.
2035 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2036 char *, so that we don't have to test for file existence
2037 separately from opening the file for reading. This removes a race
2038 fixes a permission-checking problem, and simplifies the code.
2040 (file_p): Remove; no longer needed.
2042 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2044 Omit glyphs initialization at startup.
2045 * dispnew.c (glyphs_initialized_initially_p): Remove.
2046 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2047 (Fredraw_frame): Move actual code from here...
2048 (redraw_frame): ...to here. Add eassert. Adjust comment.
2049 (Fredraw_display): Use redraw_frame.
2050 * xdisp.c (clear_garbaged_frames): Likewise.
2052 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2054 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2055 passed to pint2str and pint2hrstr to be at most the size of the
2056 frame's decode_mode_spec_buffer. This avoids crashes with very
2057 large values of FIELD_WIDTH argument to decode_mode_spec.
2060 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2062 Fix a race with verify-visited-file-modtime (Bug#12863).
2063 Since at least 1991 Emacs has ignored an mtime difference of no
2064 more than one second, but my guess is that this was to work around
2065 file system bugs that were fixed long ago. Since the race is
2066 causing problems now, let's remove that code.
2067 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2068 whose time stamp is off by no more than a second. Insist that the
2069 file time stamps match exactly.
2071 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2073 * frame.h (struct frame): Convert external_tool_bar member to
2074 1-bit unsigned bitfield.
2075 * termhooks.h (struct terminal): Remove mouse_moved member since
2076 all users are long dead. Adjust comment on mouse_position_hook.
2078 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2080 Simplify by using FOR_EACH_FRAME here and there.
2081 * frame.c (next_frame, prev_frame, other_visible_frames)
2082 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2083 * w32term.c (x_window_to_scroll_bar): Likewise.
2084 * window.c (window_list): Likewise.
2085 * xdisp.c (x_consider_frame_title): Likewise.
2086 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2087 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2088 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2089 * xmenu.c (menubar_id_to_frame): Likewise.
2090 * xselect.c (frame_for_x_selection): Likewise.
2091 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2092 (x_window_to_menu_bar): Likewise.
2093 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2095 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2097 * data.c (Qdefalias_fset_function): Now static.
2099 Another tweak to vectorlike_header change.
2100 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2101 Remove, and replace all uses with ...
2102 (next_in_free_list, set_next_in_free_list):
2103 New functions, which respect C's aliasing rules better.
2105 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2107 * window.c (list4i): Rename from 'quad'. All uses changed.
2108 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2110 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2112 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2113 warning about mixing declarations and code in ISO C90.
2115 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2117 * window.c (Fsplit_window_internal): Set combination limit of
2118 new parent window to t iff Vwindow_combination_limit is t;
2119 fixing a regression introduced with the change from 2012-09-22.
2120 (Fset_window_combination_limit): Fix doc-string.
2122 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2124 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2125 amount when the scroll margins are too large. When scrolling
2126 backwards in the buffer, give up if cannot reach point or the
2127 scroll margin within a reasonable number of screen lines.
2128 Fixes point position in window under scroll-up/down-aggressively when
2129 point is positioned many lines beyond the window top/bottom.
2132 * ralloc.c (relinquish): If real_morecore fails to return memory
2133 to the system, don't crash; instead, leave the last heap
2134 unchanged and return. (Bug#12774)
2136 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2138 * lisp.h (AUTOLOADP): New macro.
2139 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2140 * data.c (Ffset): Remove special ad-advice-info handling.
2141 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2143 (Finteractive_form): Simplify.
2144 (Fquo): Don't insist on having at least 2 arguments.
2145 (Qdefalias_fset_function): New var.
2147 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2149 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2151 * nsfont.m (Qcondensed, Qexpanded): New variables.
2152 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2153 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2155 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2157 Fix recently introduced crash on MS-Windows (Bug#12839).
2158 * w32term.h (struct scroll_bar): Use convenient header.
2159 (SCROLL_BAR_VEC_SIZE): Remove.
2160 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2162 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2164 Tweak last vectorlike_header change.
2165 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2166 vectorlike object on the free list. This is introduced to avoid
2167 some (but not all) pointer casting and aliasing problems, see
2168 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2169 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2171 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2173 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2175 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2176 been removed, so remove them here also.
2178 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2180 * doc.c (Fdocumentation): Handle new property
2181 dynamic-docstring-function to replace the old ad-advice-info.
2183 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2185 * fns.c (Qeql, hashtest_eq): Now static.
2187 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2189 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2190 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2191 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2192 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2194 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2196 Use same hash function for hashfn_profiler as for hash_string etc.
2197 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2198 * lisp.h (sxhash_combine): New inline function, with the contents
2199 of the old SXHASH_COMBINE.
2200 * profiler.c (hashfn_profiler): Use it, instead of having a
2201 special hash function containing a comparison that always yields 1.
2203 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2205 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2206 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2207 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2210 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2212 * image.c (xpm_make_color_table_h): Fix compiler error because
2213 make_hash_table changed.
2215 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2217 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2219 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2221 Use ad-hoc comparison function for the profiler's hash-tables.
2222 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2223 (make_log): Use them.
2224 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2225 call Fequal any more.
2226 (Ffunction_equal): New function.
2227 (cmpfn_profiler, hashfn_profiler): New functions.
2228 (syms_of_profiler): Initialize them.
2229 * lisp.h (struct hash_table_test): New struct.

2234 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2235 (hash_lookup, hash_remove_from_table): Move assertion checking of
2236 hashfn result here. Check hash-equality before calling cmpfn.
2237 (Fmake_hash_table): Adjust call to make_hash_table.
2238 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
2239 (syms_of_fns): Initialize them.

2243 * print.c (print_object): Adjust to new hash-table struct.
2244 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
2246 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2248 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2249 value of w32-scroll-lock-modifier is neither nil nor one of the
2250 known key modifiers. (Bug#12806)
2252 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2254 Shrink struct vectorlike_header to the only size field.
2255 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2257 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2258 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2259 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2260 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2261 information from the vector header. Adjust comment.
2262 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
2263 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
2265 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
2266 (struct vectorlike_header): Remove next member. Adjust comment.

2269 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
2270 (sweep_string, lisp_malloc): Remove useless prototypes.
2271 (enum mem_type): Adjust comment.
2272 (NEXT_IN_FREE_LIST): New macro.
2273 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2274 (Fmake_bool_vector): Likewise.
2275 (struct large_vector): New type to represent allocation unit for
2276 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2277 (large_vectors): Change type to struct large_vector.
2278 (allocate_vector_from_block): Simplify.
2279 (PSEUDOVECTOR_NBYTES): Replace with...
2280 (vector_nbytes): ...new function. Adjust users.
2281 (sweep_vectors): Adjust processing of large vectors.
2282 (allocate_vectorlike): Likewise.
2283 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2284 Add easserts. Adjust XSETPVECTYPESIZE usage.
2285 (allocate_buffer): Use BUFFER_PVEC_INIT.
2286 (live_vector_p): Adjust to match large vector.
2287 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2288 * buffer.h (struct buffer): Add next member.
2289 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2291 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2292 * fns.c (internal_equal): Adjust to match enum pvec_type change.
2293 (copy_hash_table): Adjust to match vector header change.
2294 * lread.c (defsubr): Use XSETPVECTYPE.
2295 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
2296 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
2297 (xvecsize): New command.
2299 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2301 * keyboard.c (event_to_kboard): Do not dereference
2302 frame_or_window field of SELECTION_REQUEST_EVENT
2303 and SELECTION_CLEAR_EVENT events (Bug#12814).
2304 * xterm.h (struct selection_input_event): Adjust comment.
2306 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2308 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2309 such as Scroll Lock, if the respective keys are treated as
2310 function keys, not as modifiers. This avoids destroying non-ASCII
2311 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2313 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2315 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2317 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2319 Restore some duplicate definitions (Bug#12814).
2320 This undoes part of the 2012-11-03 changes. Some people build
2321 with plain -g rather than with -g3, and they need the duplicate
2322 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2323 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2324 Define as macros, as well as as enums or as constants.
2326 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2328 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2329 to keypad keys (Bug#12816).
2331 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2333 Minor adjustments of recently-changed frame functions.
2334 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2335 known to be a frame (we're in the FRAMEP branch).
2336 * lisp.h (Qframep): Remove decl. frame.h declares this.
2337 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2338 since they're meant for Lisp fixnum values.
2340 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2342 * window.c (Fwindow_combination_limit): Revert to the only
2343 required argument and adjust docstring as suggested in
2344 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html

2347 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2349 Widely used frame validity and checking functions.
2350 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
2351 * frame.c (decode_live_frame, decode_any_frame): New functions.
2352 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
2353 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
2354 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2355 (Fframe_pointer_visible_p): Use decode_any_frame.
2356 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2357 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2358 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2359 (Fframe_focus): Likewise. Allow zero number of arguments.
2361 (frame_buffer_list, frame_buffer_predicate): Remove.
2362 * lisp.h (frame_buffer_predicate): Remove prototype.
2363 * buffer.c (Fother_buffer): Use decode_any_frame.
2364 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2365 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2366 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2367 (Fclose_font, Ffont_info): Use decode_live_frame.
2368 * fontset.c (check_fontset_name): Likewise.
2369 * terminal.c (Fframe_terminal): Likewise.
2370 * w32fns.c (check_x_frame): Likewise.
2371 * window.c (Fminibuffer_window, Fwindow_at)
2372 (Fcurrent_window_configuration): Likewise.
2373 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2374 Likewise. Allow zero number of arguments. Adjust docstring.
2375 * dispnew.c (Fredraw_frame): Likewise.
2376 * xfaces.c (frame_or_selected_frame): Remove.
2377 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2378 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2379 (Fframe_face_alist): Use decode_live_frame.
2380 * xfns.c (check_x_frame): Likewise.
2382 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2384 * window.c (quad): New function.
2385 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2386 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2387 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2388 (Fwindow_line_height): Use it.
2389 (Fwindow_fringes): Use list3.
2390 (Fwindow_scroll_bars): Use list4.
2391 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2392 (Fwindow_combination_limit): Allow zero number of arguments.
2394 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2396 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2398 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2399 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2400 file descriptor 2 for standard error. (Bug#12805)
2402 2012-11-05 Chong Yidong <cyd@gnu.org>
2404 * process.c (wait_reading_process_output): Revert previous change.
2406 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2408 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2409 This removes code that has been obsolete since around 1990.
2410 * callproc.c (Fcall_process):
2412 * process.c (create_process):
2413 * term.c (dissociate_if_controlling_tty):
2414 Assume setsid exists.
2415 * callproc.c (child_setup): Assume setpgid exists and behaves as
2416 per POSIX.1-1988 or later.
2417 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2418 * emacs.c (shut_down_emacs):
2419 * sysdep.c (sys_suspend, init_foreground_group):
2420 Assume getpgrp behaves as per POSIX.1-1998 or later.
2421 * msdos.c (setpgrp): Remove.
2422 (tcgetpgrp, setpgid, setsid): New functions.
2423 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2424 * term.c (no_controlling_tty): Remove; unused.
2425 * w32proc.c (setpgrp): Remove.
2426 (setsid, tcgetpgrp): New functions.
2428 Simplify by assuming __fpending.
2429 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2430 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2431 Do not assume that __fpending's result fits in int.
2433 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2435 Remove EMACS_OUTQSIZE+sleep hack.
2436 * dispnew.c (update_frame_1): Remove hack for terminals slower
2437 than 2400 bps, which throttled Emacs by having it sleep.
2438 This code hasn't worked since at least 2007, when the multi-tty stuff
2439 was added, and anyway those old terminals are long dead.
2440 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2441 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2443 Fix data-loss with --version (Bug#9574).
2444 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2445 as we can't assume that emacs_strerror is initialized, and strerror
2446 is good enough here.
2447 (main): Invoke atexit earlier, to catch earlier instances of
2448 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2450 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2452 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2453 (keyDown): Remap keypad keys to X11 virtual key codes.
2455 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2457 Fix data-loss with --batch (Bug#9574).
2458 * emacs.c: Include <close-stream.h>.
2459 (close_output_streams): New function.
2460 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2461 and handles errors appropriately.
2462 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2465 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2466 The symptom is a diagnostic "GLib-WARNING **: In call to
2467 g_spawn_sync(), exit status of a child process was requested but
2468 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2469 waitpid(), so exit status can't be returned." The diagnostic
2470 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2471 The real bug is a race condition between Emacs and glib: Emacs
2472 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2473 so that glib can't find it. Work around the bug by invoking
2474 waitpid only on subprocesses that Emacs itself creates.
2475 * process.c (create_process, record_child_status_change):
2476 Don't use special value -1 in pid field, as the caller now must
2477 know the pid rather than having the callee infer it.
2478 The inference was sometimes incorrect anyway, due to another race.
2479 (create_process): Set new 'alive' member if child is created.
2480 (process_status_retrieved): New function.
2481 (record_child_status_change): Use it.
2482 Accept negative 1st argument, which means to wait for the
2483 processes that Emacs already knows about. Move special-case code
2484 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2485 processes that have already been waited for, by testing and
2486 clearing new 'alive' member.
2487 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2488 now does this internally.
2489 (handle_child_signal): Let record_child_status_change do all
2490 the work, since we do not want to reap all exited child processes,
2491 only the child processes that Emacs itself created.
2492 * process.h (Lisp_Process): New boolean member 'alive'.
2494 Omit duplicate definitions no longer needed with gcc -g3.
2495 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2496 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2497 Define only as macros. There's no longer any need to also define
2498 these symbols as enums or as constants, since we now assume
2499 gcc -g3 when debugging.
2501 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2503 * lisp.mk: Adjust comments to the fact that term/internal is now
2504 loaded from loadup.el.
2506 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2507 (msdos_fatal_signal): New function.
2508 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2511 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2512 for GCC versions before 4.
2513 (emacs_raise): Define to call msdos_fatal_signal.
2515 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2516 iterator when starting in the middle of a display or overlay
2519 2012-11-03 Chong Yidong <cyd@gnu.org>
2521 * process.c (wait_reading_process_output): Clean up the last
2524 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2526 * process.c (wait_reading_process_output): Avoid a race condition
2527 with SIGIO delivery (Bug#11536).
2529 2012-11-03 Chong Yidong <cyd@gnu.org>
2531 * buffer.c (cursor_type): Untabify docstring.
2533 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2535 * frame.h (struct frame): Drop can_have_scroll_bars member
2536 which is meaningless for a long time. Adjust comments.
2537 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2538 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2540 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2542 * window.c (decode_next_window_args): Update window arg after
2543 calling decode_live_window and so fix crash reported at
2544 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2545 by Juanma Barranquero <lekktu@gmail.com>.
2546 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2547 * font.c (Ffont_at): Likewise.
2549 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2551 * widget.c (resize_cb): New function.
2552 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2553 (EmacsFrameResize): Check if all is up to date before changing frame
2556 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2558 Implement backtrace output for fatal errors on MS-Windows.
2559 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2560 (BACKTRACE_LIMIT_MAX): New macro.
2561 (w32_backtrace): New function.
2562 (emacs_abort): Use w32_backtrace when the user chooses not to
2563 attach a debugger. Update the text of the abort dialog.
2565 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2567 Window-related stuff cleanup here and there.
2568 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2569 Use decode_any_window.
2570 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2571 * xdisp.c (Fformat_mode_line): Likewise.
2572 * font.c (Ffont_at): Use decode_live_window.
2573 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2574 * window.c (decode_next_window_args): Likewise.
2575 (decode_any_window): Remove static.
2576 * window.h (decode_any_window): Add prototype.
2577 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2578 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2581 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2583 Remove pad from struct input_event.
2584 * termhooks.h (struct input_event): Remove padding field.
2586 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2587 member is never cons for a long time. Adjust comment.
2588 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2589 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2590 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2591 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2593 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2595 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2597 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2599 Fix crash when using Emacs as commit editor for git (Bug#12697).
2600 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2601 and it is configured in conf_post.h.
2602 (Fcall_process): Don't invoke both setsid and setpgid; the former
2603 is enough, if it exists.
2604 * callproc.c (Fcall_process, child_setup):
2605 * process.c (create_process): Use setpgid.
2606 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2608 * dispnew.c (init_display): Initialize the foreground group
2609 if we are running a tty display.
2610 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2611 * lisp.h (init_foreground_group): New decl.
2612 * sysdep.c (inherited_pgroup): New static var.
2613 (init_foreground_group, tcsetpgrp_without_stopping)
2614 (narrow_foreground_group, widen_foreground_group): New functions.
2615 (init_sys_modes): Narrow foreground group.
2616 (reset_sys_modes): Widen foreground group.
2618 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2620 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2622 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2624 * minibuf.c (read_minibuf): Restore current buffer since
2625 choose_minibuf_frame calling Fset_frame_selected_window may
2626 change it (Bug#12766).
2628 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2630 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2632 2012-10-30 Kenichi Handa <handa@gnu.org>
2634 * font.c (Ffont_at): If WINDOW is specified and it is not
2635 displaying the current buffer, signal an error.
2637 2012-10-29 Daniel Colascione <dancol@dancol.org>
2639 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2640 In preparation for fixing bug#12739, move these functions from
2643 * coding.h, coding.c: ... to here, and compile them only when
2644 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2645 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2647 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2649 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2650 (timer_loop, getitimer, setitimer): Use it instead of
2651 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2653 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2656 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2658 * nsterm.m (NO_APPDEFINED_DATA): New define.
2659 (last_appdefined_event_data): New variable
2660 (last_appdefined_event): Remove.
2661 (ns_select): Initialize t from last_appdefined_event_data instead
2662 of [last_appdefined_event data1].
2663 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2664 remove last_appdefined_event (Bug#12698).
2666 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2668 * frame.c (x_set_font): Catch internal error.
2670 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2672 Avoid overflow in w32 implementation of interval timers.
2673 When possible, for ITIMER_PROF count only times the main thread
2675 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2676 'volatile ULONGLONG' types. All the other data which was
2677 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2678 (GetThreadTimes_Proc): New typedef.
2679 (w32_get_timer_time): New function, returns a suitable time value
2681 (timer_loop): Enter critical section when accessing ULONGLONG
2682 values of the itimer_data struct, as these accesses are no longer
2683 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2684 Remove unused variable.
2685 (init_timers): Initialize s_pfn_Get_Thread_Times.
2686 (start_timer_thread): Don't assign itimer->caller_thread here.
2687 (getitimer): Assign itimer->caller_thread here.
2688 (setitimer): Always call getitimer to get the value of ticks_now.
2689 (sys_spawnve): Avoid compiler warning about format mismatch.
2691 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2693 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2694 mouse movement events if the menu bar is active. This avoids
2695 producing a busy "hour-glass" cursor by Windows if the mouse
2696 pointer is positioned over a tooltip shown for some menu item.
2698 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2700 Don't assume process IDs fit in int.
2701 * emacs.c (shut_down_emacs) [!DOS_NT]:
2702 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2703 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2704 Use pid_t, not int, to store process IDs, as 'int'
2705 is not wide enough on a few platforms (e.g., AIX and IRIX).
2707 2012-10-23 Kenichi Handa <handa@gnu.org>
2709 The following change is to make face-font-rescale-alist work
2710 correctly for non-ASCII fonts.
2712 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2713 (font_open_for_lface): Handle Vface_font_rescale_alist.
2715 2012-10-23 Chong Yidong <cyd@gnu.org>
2717 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2719 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
2721 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
2723 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2725 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2728 2012-10-21 Glenn Morris <rgm@gnu.org>
2730 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2732 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2734 Port to OpenBSD 5.1.
2735 * frame.c (Fmouse_position, Fmouse_pixel_position):
2736 * xdisp.c (produce_stretch_glyph):
2737 Declare local vars only when they're needed.
2738 This is clearer and avoids a warning on OpenBSD about unused vars.
2739 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2740 This is safer, and avoids OpenBSD warnings about unused vars.
2741 * keyboard.c (record_menu_key): Remove unnecessary decl.
2742 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2743 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2744 as our definition clashes with OpenBSD's.
2745 * xfaces.c (load_face_colors, check_lface_attrs)
2746 (get_lface_attributes_no_remap, get_lface_attributes)
2747 (lface_fully_specified_p, x_supports_face_attributes_p)
2748 (tty_supports_face_attributes_p, face_fontset, realize_face)
2749 (realize_x_face, realize_tty_face):
2750 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2751 merely Lisp_Object *. This is more informative and avoids
2752 a warning on OpenBSD about accessing beyond an object's size.
2754 2012-10-20 Chong Yidong <cyd@gnu.org>
2756 * lread.c (Fload): Doc fix (Bug#12592).
2758 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2760 * font.c (Ffont_at): Fix previous change.
2762 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2764 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2765 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
2768 * alloc.c (NSTATICS): Decrease to 0x800.
2770 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
2772 * fns.c (Fnreverse): Include the problem element when signaling an
2775 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
2777 * nsterm.m (ns_select): Check writefds before call to
2778 FD_ISSET (Bug#12668).
2780 2012-10-18 Daniel Colascione <dancol@dancol.org>
2782 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2783 (staticpro): If we run out of staticpro slots, die with an
2784 informative error instead of just calling emacs_abort.

3043 since unsigned is guaranteed to have that behavior and signed is not.
3044 (read_char): Use ptrdiff_t for string length.
3045 (get_input_pending): Remove first argument, since it was always
3046 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3047 and behave as if it had that value. Return new value of
3048 input_pending. All callers changed.
3049 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3050 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

3053 All callers changed.

3077 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3079 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3081 * commands.h (immediate_quit): Remove duplicate decl.

3092 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3093 match what GetLastError returns. Explain why the function is
3096 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3097 'is_tooltip_frame', to avoid confusion with its global namesake.
3099 2012-10-08 Daniel Colascione <dancol@dancol.org>
3101 * xdisp.c (start_hourglass): Call w32_note_current_window when
3102 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3103 build that caused Emacs to display the hourglass cursor forever.
3105 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3106 which is broken under remote desktop, calculate the number of
3107 colors available for a display based on the display's number of
3108 planes and number of bits per pixel per plane. (bug#10397).
3110 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3112 * nsfont.m (Vfonts_in_cache): New variable.
3113 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3114 are used. Add cached fonts to Vfonts_in_cache.
3115 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3117 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3119 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now

3137 ($(BLD)/w32heap.$(O)):
3138 ($(BLD)/w32menu.$(O)):
3139 ($(BLD)/w32proc.$(O)): Add w32common.h.
3141 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3143 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3145 2012-10-08 Daniel Colascione <dancol@dancol.org>
3147 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3148 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3149 accidental message numbering hole. Change other messages to

3167 Remove duplicate definitions.
3169 * w32fns.c: Include w32common.h; include w32heap.h only in
3172 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3173 Use `report_file_error' instead of `error' in order to better
3174 inform users of what went wrong. Increase NTGUI_UNICODE file
3175 dialog box file name length to 32k, the maximum allowed by the NT
3178 * w32common.h: New file.
3179 (ROUND_UP, ROUND_DOWN, get_page_size)

3183 (OS_NT, os_subtype, cache_system_info): Move here.
3185 * unexw32.c, unexcw.c: Include w32common.h.
3187 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3188 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3189 to call syms_of_w32select.
3191 * cygw32.h: Remove obsolete EXFUN declarations.
3193 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

3205 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3207 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3210 2012-10-08 Daniel Colascione <dancol@dancol.org>
3212 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3213 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3214 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3215 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3216 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3217 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3218 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3219 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3220 now a supported configuration.
3222 * Makefile.in: consolidate image variables into LIBIMAGE; add
3223 W32_OBJ and W32_LIBS. Compile new files.
3226 (_DebPrint) declare tracing facility for W32 debugging. We need
3227 to unify tracing later.
3229 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3230 unconditional use of W32 Unicode functions. Cygwin runs only on
3231 100% Unicode operating systems.
3233 * cygw32.c: New file. Define Cygwin-specific facilities.
3234 (Fcygwin_convert_path_to_windows)
3235 (Fcygwin_convert_path_from_windows): New user functions for
3236 accessing Cygwin path-munging routines.
3238 * cygw32.h: New file.
3239 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3240 UTF-16LE strings temporarily inside non-Lisp-visible string
3243 (w32_strerror): Just what it says on the tin.
3245 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3246 also run for Cygwin; both systems have the same problem with using
3247 GUI facilities in a forked child. Also call syms_of_cygw32,
3248 syms_of_w32select in correct places.
3250 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3251 needs fork-then-exec for daemon launching.
3253 * font.h: Include frame.h.
3255 * image.c: Use the image library cache machinery only when we're
3256 compiling for native WINDOWSNT; Cygwin can use shared libraries
3257 like any other Unixlike system.
3259 * keyboard.c: Clarify a comment regarding the input loop.
3261 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3262 functions directly instead of trying to detect at runtime that our
3263 host operating system supports them. We make this change for two
3264 reasons: Cygwin lacks support for the multibyte character
3265 conversion functions used by the legacy menu code, and Cygwin
3266 never needs to rely on non-Unicode APIs.
3268 * unexw32.c (hinst): Declare extern.
3270 * w32.c: Change header order;
3271 (w32_strerror): Move to w32fns.c because we need it for
3272 non-WINDOWSNT builds.
3274 * w32.h: Add #error macro to make sure we don't include w32.h for
3275 Cygwin builds. Remove w32select declarations.
3277 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3278 w32fns.c. w32console.c is WINDOWSNT-only.
3280 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3281 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3283 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3284 (w32_major_version, w32_minor_version, w32_build_number)
3285 (os_subtype, sound_type): Define here
3286 (w32_defined_color): Make color parameter const for consistency
3287 with other _defined_color functions.
3288 (w32_createwindow): Unconditionally call w32_init_class instead of
3289 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3290 through the code is complex and unnecessary because class
3291 registration is practically free.
3292 (w32_name_of_message): New EMACSDEBUG-only function.
3293 (Fset_message_beep): Move here
3294 (Fx_open_connection): Require that the display name for Windows be
3295 "w32" for consistency, emacsclient disambiguation, and maybe, one
3296 day, multi-window-system support.
3297 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3298 Cygwin files for W32 GUI facilities, since these clearly don't
3299 expect Cygwin names.
3300 (_DebPrint): Define.
3301 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
3302 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
3303 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
3304 (w32_last_error): Remove.
3306 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
3308 * w32heap.c (syspage_mask): Declare here.
3309 (cache_system_info): Remove.
3311 * w32inevt.c (faked_key): Define globally, not statically.
3312 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
3313 (w32_console_toggle_lock_key): Move to w32fns.c.
3315 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
3317 * w32proc.c (_DebPrint): Move to w32fns.c.
3318 * w32select.c: Include string.h, stdio.h for Cygwin.
3319 * w32select.h: New File.
3321 * w32term.c: Include io.h for non-CYGWIN builds; needed for
3323 (w32_message_fd): New variable. Under Cygwin, holds the file
3324 descriptor the system used to tell us about pending thread
3327 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3328 that prevented compilation under non-WINDOWSNT systems.
3330 (w32_initialize): Open /dev/windows and assign it to
3331 w32_message_fd. Provide w32 feature.
3333 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3334 (WM_EMACS_INPUT_READY): add.
3335 (prepend_msg, w32_message_fd): Declare globally.
3338 (keyboard_handle): Use only when WINDOWSNT.
3339 (notify_msg_ready): New function. Posts a message to the main
3340 thread's message queue under CYGWIN, which wakes up the main
3341 thread from select(2) by making the /dev/windows file descriptor
3342 ready. Under WINDOWSNT, it sets an event the same way the old
3345 (post, prepend_msg): Actually call notify_msg_ready instead of
3346 setting the input event directly.
3348 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3350 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3351 but it still has blocs in it, don't return it to the system,
3352 instead of aborting. (Bug#12402)
3354 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3356 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
3358 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
3359 MAC_OS_X_VERSION_10_6.
3360 (syms_of_nsterm): Remove comment about Panther and above for
3362 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
3363 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
3364 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
3366 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
3367 MAC_OS_X_VERSION_10_4.
3369 * nsmenu.m (fillWithWidgetValue:): Remove code for <
3370 MAC_OS_X_VERSION_10_2.
3372 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
3374 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
3375 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
3377 * nsterm.m (ns_in_resize): Remove (Bug#12479).
3378 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
3379 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
3380 Remove ns_in_resize check.
3381 (ns_clear_frame_area): Remove resize handle code.
3383 * nsfns.m (ns_in_resize): Remove.
3384 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
3385 Remove ns_in_resize check.
3387 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
3389 Improve sys_siglist detection.
3390 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3391 defined as a macro, as is done in Solaris.
3392 (sys_siglist_entries): New macro.
3393 (save_strsignal): Use it.
3394 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3395 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3397 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3399 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3400 fullscreen/Fullscreen.
3402 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3403 tobar_height is new.
3405 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3406 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3407 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
3408 (windowDidResize:): Check for correct window if old style fullscreen.
3409 Capitalize word in comment. Remove incorrect comment.
3410 (initFrameFromEmacs:): tbar_height renamed tibar_height.
3411 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
3412 error in drawing background.
3413 (toggleFullScreen:): Remove comment. Rearrange calls.
3414 Set toolbar values to zero, save old height in tobar_height.
3415 Restore tool bar height when leaving fullscreen.
3416 (canBecomeMainWindow): New function.
3418 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3420 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3422 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3424 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3426 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3427 that time stamps of directories could also be changed.
3428 Don't request the too broad GENERIC_WRITE, only the more restrictive
3429 FILE_WRITE_ATTRIBUTES access rights.
3431 * fileio.c (Fset_file_times): Special-case ignoring errors for
3432 directories only on MSDOS, not on MS-Windows.
3434 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3436 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3438 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3440 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3441 see whether CreateFile failed.
3443 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3445 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3446 to avoid similar races.
3447 * keyboard.c (pending_signals): Now bool, not int.
3449 Port timers to OpenBSD, plus check for timer failures.
3450 OpenBSD problem reported by Han Boetes.
3451 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3453 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3454 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3455 like OpenBSD, which has timer_settime but does not declare it.
3456 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3457 whether to use itimerspec-related primitives. All uses of
3458 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3460 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3462 * profiler.c (handle_profiler_signal): Fix a malloc race
3463 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3465 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3467 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3469 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3471 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3472 consistent with the change in return value of 'safe_strsignal'.
3474 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3476 Prefer plain 'static' to 'static inline' (Bug#12541).
3477 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3478 (bidi_set_sor_type, bidi_push_embedding_level)
3479 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3480 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

3484 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3485 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3486 Now 'static', not 'static inline'.
3488 Count overruns when profiling; change units to ns.
3489 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3490 Give extra weight to samples after overruns, to attempt to count
3491 the time more accurately.
3492 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3493 the underlying primitives nominally do ns.
3494 (Fprofiler_cpu_start): Document the change. Mention that
3495 the sampling intervals are only approximate.
3497 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3499 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3501 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3502 case for the special 0 coding-system.
3504 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3505 (Fmake_overlay): Remove redundant tests.
3506 (fix_start_end_in_overlays): Remove redundant recentering.
3508 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3510 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3511 Update dependencies.
3513 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3515 Fix a malloc race condition involving strsignal.
3516 A signal can arrive in the middle of a malloc, and Emacs's signal
3517 handler can invoke strsignal, which can invoke malloc, which is
3518 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3519 Fix it by altering the signal handler so that it does not invoke
3521 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3522 * process.c (status_message): Use const pointer, in case strsignal
3523 is #defined to safe_strsignal.
3524 * sysdep.c (sys_siglist, init_signals): Always define and
3525 initialize a substitute sys_siglist if the system does not define
3526 one, even if HAVE_STRSIGNAL.
3527 (safe_strsignal): Rename from strsignal. Always define,
3528 using sys_siglist. Return a const pointer.
3529 * syssignal.h (safe_strsignal): New decl.
3530 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3532 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3534 * w32proc.c (timer_loop): Fix code that waits for timer
3535 expiration, to avoid high CPU usage.
3537 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3539 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3540 (sweep_weak_table): Remove redundant prototypes.
3542 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3544 * emacs.c: Move the inclusion of TERM_HEADER after including
3545 windows.h on WINDOWSNT. This avoids compilation problems with
3548 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3550 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3551 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3552 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3553 as the previous version used 'void *'.
3555 * ralloc.c (ROUNDUP): Fix last change.
3556 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3559 * w32proc.c <disable_itimers>: New static flag.
3560 (init_timers): Initialize it to zero, after creating the critical
3561 sections used by the timer threads.
3562 (term_timers): Set to 1 before deleting the critical sections.
3563 (getitimer, setitimer): If disable_itimers is non-zero, return an
3564 error indication without doing anything. Reported by Fabrice
3565 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3566 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3568 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3571 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3572 term_ntproc after all the other bookkeeping, to get timers working
3573 as long as possible.
3575 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3577 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3578 Suggested by Juri Linkov in
3579 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3581 Prefer plain 'static' to 'static inline' (Bug#12541).
3582 With static functions, modern compilers inline pretty well by
3583 themselves; advice from programmers often hurts as much as it helps.
3584 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3585 this change shrinks the text size of the Emacs executable by 1.1%
3586 without affecting CPU significantly in my benchmark.
3587 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
3588 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

3662 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
3663 Now 'static', not 'static inline'.
3666 (bidi_copy_it): Do the whole copy with a single memcpy.
3667 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3669 Revert the FOLLOW-SYMLINKS change for file-attributes.
3670 Doing it right would require several changes to Tramp, and there's
3671 not enough time to get that tested before the freeze today.
3672 * dired.c (directory_files_internal, Ffile_attributes):
3675 * frame.c (x_report_frame_params): Port better to wider ints.
3676 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3677 or that pointers can be printed in 15 decimal digits.
3678 Avoid GCC warnings if EMACS_UINT is wider than a pointer.
3680 2012-09-30 Fabrice Popineau <fabrice.popineau@supelec.fr>

3695 compatibility with x64.
3697 * w32heap.h: Adjust prototypes and declarations.
3699 * w32heap.c (RVA_TO_PTR, allocate_heap, sbrk, init_heap)
3700 (round_heap): Use DWORD_PTR, ptrdiff_t and size_t instead of
3701 DWORD, long, and unsigned long, for compatibility with x64.
3702 (allocate_heap) [_WIN64]: Reserve 32GB of memory.

3880 (handle_profiler_signal): Rename from sigprof_handler_1,
3881 for consistency with other handlers. Do not check whether
3882 cpu_log is a hash-table if garbage collecting, since it

3885 for consistency with other handlers.
3886 (setup_cpu_timer): New function, with much of what used to be in

3888 Prefer timer_settime if available, and prefer
3889 thread cputime clocks, then process cputime clocks, then
3890 monotonic clocks, to the old realtime clock. Use make_timeval
3891 to round more-correctly when falling back to setitimer.
3892 (Fprofiler_cpu_start): Use it.
3893 (Fprofiler_cpu_stop): Prefer timer_settime if available.

4163 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4165 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4166 fatal_error_backtrace.
4168 * w32proc.c (sys_kill): Undo last change: don't do anything when
4169 invoked to deliver SIGABRT to our own process. This is now
4170 handled by emacs_raise.
4172 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4174 * w32term.c (w32_read_socket): Remove leftover reference to
4175 interrupt_input_pending.
4177 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4179 Do not use SA_NODEFER.
4180 Problem reported by Dani Moncayo in
4181 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4183 * sysdep.c (emacs_abort): Do not reset signal handler.
4184 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4185 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4186 wanted even on POSIXish hosts, and it doesn't work on Windows.
4188 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4190 * xterm.c (x_term_init): Call fixup_locale before and after calling
4191 gtk_init (Bug#12392).
4193 2012-09-23 Chong Yidong <cyd@gnu.org>
4195 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4196 Vdynamic_library_alist.
4198 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4199 (Fgnutls_available_p): Caller changed.
4201 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4202 (Flibxml_parse_xml_region): Likewise.
4204 * dispextern.h (struct image_type): Remove arg from init function.
4206 * image.c (Finit_image_library, lookup_image_type)
4207 (define_image_type): Remove now-unneeded second arg.
4208 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4209 (init_tiff_functions, init_gif_functions, init_svg_functions):
4210 Arglist and w32_delayed_load calling convention changed.
4211 (gs_type): Remove init_gs_functions; there is no such function.
4212 (valid_image_p, make_image): Fix caller to lookup_image_type.
4214 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4216 Simplify and avoid signal-handling races (Bug#12471).
4218 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4219 Avoid recursive loop if there's a fatal error in the function itself.
4220 * atimer.c (pending_atimers):
4221 * blockinput.h: Don't include "atimer.h"; no longer needed.
4222 (interrupt_input_pending): Remove. All uses removed.
4223 pending_signals now counts both atimers and ordinary interrupts.
4224 This is less racy than having three separate pending-signal flags.
4225 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4227 Rename from their upper-case counterparts BLOCK_INPUT,
4228 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4229 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4230 This makes it easier to access volatile variables more accurately.
4231 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4232 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4233 that's more reliable if the code is buggy and sets
4234 interrupt_input_blocked to a negative value. All uses changed.
4235 * atimer.c (deliver_alarm_signal):
4236 Remove. No need to deliver this to the parent; any thread can
4237 handle this signal now. All uses replaced by underlying handler.
4238 * atimer.c (turn_on_atimers):
4239 * dispnew.c (handle_window_change_signal):
4240 * emacs.c (handle_danger_signal):
4241 * keyboard.c (kbd_buffer_get_event):
4242 Don't reestablish signal handler; not needed with sigaction.
4243 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4245 Rework to avoid unnecessary accesses to volatile variables.
4246 (UNBLOCK_INPUT_TO): Now a function.
4247 (totally_unblock_input, unblock_input): New decls.
4248 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4249 (init_data): Remove. Necessary stuff now done in init_signal.
4250 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4251 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4252 (fatal_error_code): Remove; no longer needed.
4253 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4254 it doesn't always backtrace. All uses changed. No need to reset
4255 signal to default, since sigaction and/or die does that for us now.
4256 Use emacs_raise (FOO), not kill (getpid (), FOO).
4257 (main): Check more-accurately whether we're dumping.
4258 Move fatal-error setup to sysdep.c
4259 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4260 * gtkutil.c (xg_get_file_name, xg_get_font):
4261 Remove no-longer-needed signal-mask manipulation.
4262 * keyboard.c, process.c (POLL_FOR_INPUT):
4263 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4264 * keyboard.c (read_avail_input): Remove.
4265 All uses replaced by gobble_input.
4266 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4267 (kbd_buffer_store_event_hold, gobble_input):
4268 (record_asynch_buffer_change) [USABLE_SIGIO]:
4269 (store_user_signal_events):
4270 No need to mess with signal mask.
4271 (gobble_input): If blocking input and there are terminals, simply
4272 set pending_signals to 1 and return. All hooks changed to not
4273 worry about whether input is blocked.
4274 (process_pending_signals): Clear pending_signals before processing
4275 them, in case a signal comes in while we're processing.
4276 By convention callers now test pending_signals before calling us.
4277 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4278 New functions, to support changes to blockinput.h.
4279 (handle_input_available_signal): Now extern.
4280 (reinvoke_input_signal): Remove. All uses replaced by
4282 (quit_count): Now volatile, since a signal handler uses it.
4283 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4284 All callers changed. Block SIGINT only if not already blocked.
4285 Clear sigmask reliably, even if Fsignal returns, which it can.
4286 Omit unnecessary accesses to volatile var.
4287 (quit_throw_to_read_char): No need to restore sigmask.
4288 * keyboard.c (gobble_input, handle_user_signal):
4289 * process.c (wait_reading_process_output):
4290 Call signal-handling code rather than killing ourselves.
4291 * lisp.h: Include <float.h>, for...
4292 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4293 (pending_signals): Now volatile.
4294 (syms_of_data): Now const if IEEE floating point.
4295 (handle_input_available_signal) [USABLE_SIGIO]:
4296 (terminate_due_to_signal, record_child_status_change): New decls.
4297 * process.c (create_process): Avoid disaster if memory is exhausted
4298 while we're processing a vfork, by tightening the critical section
4300 (send_process_frame, process_sent_to, handle_pipe_signal)
4301 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4303 (send_process): No need for setjmp/longjmp any more, since the
4304 SIGPIPE stuff is now gone. Instead, report an error if errno
4306 (record_child_status_change): Now extern. PID and W are now args.
4307 Return void, not bool. All callers changed.
4308 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4309 Remove. All uses removed. This bug should be fixed now in a
4311 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4312 and record the child status change directly. This avoids the
4313 need to futz with the signal mask.
4314 (process_fatal_action): Move here from emacs.c.
4315 (emacs_sigaction_flags): New function, containing
4316 much of what used to be in emacs_sigaction_init.
4317 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4318 caught by emacs, to make races less likely.
4319 (deliver_process_signal): Rename from handle_on_main_thread.
4321 (BACKTRACE_LIMIT_MAX): Now at top level.
4322 (thread_backtrace_buffer, threadback_backtrace_pointers):
4324 (deliver_thread_signal, deliver_fatal_thread_signal):
4325 New functions, for more-accurate delivery of thread-specific signals.
4326 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4327 (deliver_arith_signal): Handle in this thread, not
4328 in the main thread, since it's triggered by this thread.
4329 (maybe_fatal_sig): New function.
4330 (init_signals): New arg DUMPING so that we can be more accurate
4331 about whether we're dumping. Caller changed.
4332 Treat thread-specific signals differently from process-general signals.
4333 Block all signals while handling fatal error; that's safer.
4334 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4336 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4337 Ignore SIGPIPE unless batch.
4338 (emacs_backtrace): Output backtrace for the appropriate thread,
4339 which is not necessarily the main thread.
4340 * syssignal.h: Include <stdbool.h>.
4341 (emacs_raise): New macro.
4342 * xterm.c (x_connection_signal): Remove; no longer needed
4343 now that we use sigaction.
4344 (x_connection_closed): No need to mess with sigmask now.
4345 (x_initialize): No need to reset SIGPIPE handler here, since
4346 init_signals does this for us now.
4348 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4350 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4351 background rect may be larger (Bug#12245).
4353 2012-09-23 Chong Yidong <cyd@gnu.org>
4355 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4357 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4359 * .gdbinit: Just stop at fatal_error_backtrace.
4360 See Stefan Monnier's request in
4361 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4362 Remove no-longer-used query of system type.
4364 2012-09-22 Chong Yidong <cyd@gnu.org>
4366 * search.c (Freplace_match): Doc fix (Bug#12325).
4368 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4370 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4371 (Fline_end_position): Doc fix.
4373 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4375 2012-09-22 Chong Yidong <cyd@gnu.org>
4377 * dispextern.h (struct image_type): Add new slot, storing a type
4378 initialization function.
4380 * image.c (define_image_type): Call the image initializer function
4381 if it is defined. Arguments and return value changed.
4382 (valid_image_p, make_image): Callers changed.
4383 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4384 (gif_type, imagemagick_type, svg_type, gs_type):
4385 Add initialization functions.
4386 (Finit_image_library): Call lookup_image_type.
4387 (CHECK_LIB_AVAILABLE): Macro deleted.
4388 (lookup_image_type): Call define_image_type here, rather than via
4389 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4390 (syms_of_image): Move define_image_type calls for xbm_type and
4391 pbm_type to lookup_image_type.
4393 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4395 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4396 'idle_timers' from here ...
4397 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4398 lists, to avoid infloops when the timer does something stupid,
4399 like reinvoke itself with the same or smaller time-out.
4402 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4404 * window.c (Fsplit_window_internal): Handle only Qt value of
4405 Vwindow_combination_limit separately.
4406 (Qtemp_buffer_resize): New symbol.
4407 (Vwindow_combination_limit): New default value.
4410 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4412 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4413 the new overlay string. (Bug#10159)
4415 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4417 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4418 or that fprintf is async-signal-safe. POSIX doesn't require
4421 2012-09-22 Chong Yidong <cyd@gnu.org>
4423 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4426 2012-09-22 Kenichi Handa <handa@gnu.org>
4428 * composite.c (composition_reseat_it): Handle the case that a
4429 grapheme cluster is not covered by a single font (Bug#12352).
4431 2012-09-21 Chong Yidong <cyd@gnu.org>
4433 * image.c (define_image_type): Avoid adding duplicate types to
4434 image_types (Bug#12463). Suggested by Jörg Walter.
4436 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4438 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4439 (print_load_command_name): Add case LC_DATA_IN_CODE.
4440 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4442 2012-09-21 Glenn Morris <rgm@gnu.org>
4444 * eval.c (Frun_hook_with_args_until_success)
4445 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4447 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4449 * fileio.c (Ffile_selinux_context): Only call freecon when
4450 lgetfilecon succeeded.
4451 (Fset_file_selinux_context): Likewise. (Bug#12444)
4453 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4455 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4456 reordering, locate the cursor by calling set_cursor_from_row; if
4457 that fails, clear the desired glyph matrix before returning a
4458 failure indication to the caller. Fixes leaving garbled display
4459 when fast scrolling with a down-key. (Bug#12403)
4460 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4461 scrolling through multibyte text.
4463 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4465 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4466 calling mark_vectorlike since that's the one that marks the window.
4467 (mark_discard_killed_buffers): Mark the final cdr.
4468 * window.h (struct window): Move prev/next_buffers to the
4469 non-standard fields.
4470 * window.c (make_window): Initialize prev/next_buffers manually.
4472 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4474 Omit unused arg EXPECTED from socket hooks.
4475 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4476 * nsterm.m (ns_term_init):
4477 * termhooks.h (struct terminal.read_socket_hook):
4478 * w32inevt.c (w32_console_read_socket):
4479 * w32term.c (w32_read_socket):
4480 * xterm.c (XTread_socket):
4481 Omit unused arg EXPECTED. All callers changed.
4482 (store_user_signal_events): Return void, not int, since callers no
4483 longer care about the return value. All uses changed.
4485 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4487 * w32gui.h (XParseGeometry): Do not declare.
4489 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4491 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4492 Ignore 'expected'. See Eli Zaretskii in
4493 <http://bugs.gnu.org/12471#8> (last line).
4495 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4496 (XParseGeometry): Now static. Substitute extremal values for
4497 values that are out of range.
4499 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4501 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4503 * nsfns.m (XParseGeometry): Remove.
4504 (Fx_create_frame): Call x_set_offset to correctly interpret
4505 top_pos in geometry.
4507 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4508 (Fx_parse_geometry): If there is a space in string, call
4509 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4511 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4513 * search.c (scan_buffer): Use character positions in calls to
4514 region_cache_forward and region_cache_backward, not byte
4515 positions. (Bug#12196)
4517 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4518 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4520 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4521 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4522 emacs_blocked_malloc, now deleted.
4524 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4526 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4527 The workaround was for improving performance on Solaris 2.4, but
4528 is getting in the way now. Emacs will still work if someone is
4529 still running Solaris 2.4 in a museum somewhere; Sun dropped
4530 support for Solaris 2.4 in 2003.
4531 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4532 * process.c (create_process) [HAVE_WORKING_VFORK]:
4533 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4534 since Emacs no longer uses vfork on that platform.
4536 2012-09-17 Glenn Morris <rgm@gnu.org>
4538 * emacs.c: Use COPYRIGHT.
4540 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4542 Remove configure's --without-sync-input option (Bug#12450).
4543 When auditing signal-handling in preparation for cleaning it up,
4544 I found that SYNC_INPUT has race conditions and would be a real
4545 pain to fix. Since it's an undocumented and deprecated
4546 configure-time option, now seems like a good time to remove it.
4547 Also see <http://bugs.gnu.org/11080#16>.
4548 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4549 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4550 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4551 (malloc_hysteresis):
4552 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4553 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4554 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4555 (dont_register_blocks, bytes_used_when_reconsidered)
4556 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4557 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4558 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4559 Remove. All uses removed.
4560 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4561 implementation, one that depends on whether the new macro
4562 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4564 * atimer.c (run_timers, handle_alarm_signal):
4565 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4566 (handle_async_input, process_pending_signals)
4567 (handle_input_available_signal, init_keyboard):
4568 * nsterm.m (ns_read_socket):
4569 * process.c (wait_reading_process_output):
4570 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4571 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4573 * xterm.c (XTread_socket):
4575 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4576 * eval.c (handling_signal): Remove. All uses removed.
4577 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4578 All uses replaced with the SYNC_INPUT version.
4579 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4581 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4584 * font.c (Ffont_shape_gstring): Remove unused local.
4586 2012-09-16 Glenn Morris <rgm@gnu.org>
4588 * Makefile.in (clean): No longer run nextstep's clean.
4590 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4592 (ns-app): Move here from ns.mk, and simplify.
4593 (clean): Simplify nextstep entry.
4594 * ns.mk: Remove file.
4596 2012-09-17 Kenichi Handa <handa@gnu.org>
4598 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4599 not covert the last few charactes.
4601 2012-09-16 Kenichi Handa <handa@gnu.org>
4603 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4604 here, but just check the validity of glyphs in the glyph-string.
4606 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4608 * window.c (Fwindow_parameter, Fset_window_parameter):
4609 Accept any window as argument (Bug#12452).
4611 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4613 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4614 to ns_term_init to avoid memory leak.
4616 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4617 explicit retain/release.
4618 (ns_term_init): Only allow one display. Initialize outerpool and
4621 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4623 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4624 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4625 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4626 the Microsoft problem in a different way, by altering ../nt/config.nt.
4628 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4643 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4644 by lisp.h. This completes removal of setjmp.h inclusion
4645 erroneously announced in the previous commit. (Bug#12446)
4647 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4650 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4651 not defined as a macro. The latter happens on MS-Windows.
4654 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4656 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4657 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4658 Some instances of '#include <setjmp.h>' removed, if the
4659 only reason for the instance was because "lisp.h" was included.
4660 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4661 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4662 and _longjmp with the new symbols. Emacs already uses _setjmp if
4663 available, so this change affects only POSIXish hosts that have
4664 sigsetjmp but not _setjmp, such as some versions of Solaris and
4665 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4666 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4667 (png_load_body) [HAVE_PNG]:
4668 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4669 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4670 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4671 since PNG requires jmp_buf. This is the only exception to the
4672 general rule that we now use sys_setjmp and sys_longjmp.
4673 This exception is OK since this code does not change the signal
4674 mask or longjmp out of a signal handler.
4676 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4678 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4679 Include "syssignal.h", for 'main_thread'.
4681 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4683 Avoid out-of-range marker position (Bug#12426).
4684 * insdel.c (replace_range, replace_range_2):
4685 Adjust markers before overlays, as suggested by comments.
4686 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4687 Remove redundant check before calling offset_intervals.
4689 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4691 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4692 current buffer (Bug#12387).
4694 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4696 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4698 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4700 Use a more backwards-compatible timer format (Bug#12430).
4701 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4702 vector element, not from the 4th, since PSECS is now at the end.
4703 (Fcurrent_idle_time): Doc fix.
4705 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4707 Function to mark objects and remove killed buffers at once.
4708 * alloc.c (discard_killed_buffers): Rename to ...
4709 (mark_discard_killed buffers) ... new name. Add marking
4710 of remaining objects. Fix comment. Adjust users.
4711 (mark_object): Do not touch frame buffer lists here.
4712 * frame.c (delete_frame): Reset frame buffer lists here.
4714 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4716 Better workaround for GNOME bug when --enable-gcc-warnings.
4717 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4718 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4719 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4721 Simplify SIGIO usage (Bug#12408).
4722 The code that dealt with SIGIO was crufty and confusing, e.g., it
4723 played tricks like "#undef SIGIO" but these tricks were not used
4724 consistently. Simplify mostly by not #undeffing standard symbols,
4725 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4726 or not as we please) rather than "defined SIGIO" (standard symbol
4727 that we probably shouldn't #undef).
4728 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4729 Modules that need it can include it.
4730 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4731 * dispextern.h (ignore_sigio): New decl.
4732 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4733 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4734 * emacs.c (shut_down_emacs):
4735 * keyboard.c (kbd_buffer_store_event_hold):
4736 Use ignore_sigio rather than invoking 'signal' directly.
4737 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4739 (FIONREAD, SIGIO): Do not #undef.
4740 (tty_read_avail_input): Use #error rather than a syntax error.
4741 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4742 for I_PIPE, used by SETUP_SLAVE_PTY.
4743 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4744 * sysdep.c (croak): Remove; no longer needed. This bit of
4745 temporary code, with Fred N. Fish's comment that it's temporary,
4746 has been in Emacs since at least 1992!
4747 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4748 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4749 * syssignal.h (croak): Remove decl.
4750 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4751 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4752 now that we're termios-only.
4753 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4754 * term.c (dissociate_if_controlling_tty): Use #error rather than
4757 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4758 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4759 to work around GNOME bug 683906.
4760 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4761 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4762 This works around GCC bug 54561.
4764 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4766 More fixes for 'volatile' and setjmp/longjmp.
4767 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4768 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4769 (png_load_body) [HAVE_PNG]:
4770 (jpeg_load_body) [HAVE_JPEG]:
4771 New function, with most of the old parent function's body.
4772 (png_load) [HAVE_PNG]:
4773 (jpeg_load) [HAVE_JPEG]:
4774 Invoke the new function, to avoid longjmp munging our locals.
4775 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4776 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4777 longjmp is passed 2, as the C standard doesn't guarantee this.
4778 Instead, store the failure code into mgr->failure_code.
4780 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4782 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4783 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4784 (syms_of_keyboard): Remove support for unread-command-char.
4786 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4788 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4789 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4790 violation. (Bug#12426)
4792 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4794 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4796 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4798 * eval.c: Add `inhibit-debugger'.
4799 (Qinhibit_debugger): New symbol.
4800 (call_debugger): Bind it instead of Qdebug_on_error.
4801 (maybe_call_debugger): Test Vinhibit_debugger.
4802 (syms_of_eval): Define inhibit-debugger.
4803 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4804 (syms_of_xdisp): Remove inhibit-debug-on-message.
4806 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4808 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4809 If a nonvolatile local variable is written before a _longjmp to
4810 the frame containing the variable, and is read after the _longjmp,
4811 the value read is indeterminate. Some local variables of type
4812 'struct handler' and 'struct catchtag' are used in this way, so
4813 mark each of their slots as volatile if the slot can be set before
4814 _longjmp and read afterwards.
4815 * lisp.h (struct handler): var and chosen_clause are now volatile.
4816 (struct catchtag): val, next, and pdlcount are now volatile.
4818 * bidi.c (bidi_push_it, bidi_pop_it):
4819 * fns.c (copy_hash_table):
4820 * image.c (define_image_type):
4821 * keyboard.c (kbd_buffer_store_event_hold):
4822 * process.c (Fprocess_send_eof):
4823 * xfaces.c (x_create_gc) [HAVE_NS]:
4824 * xgselect.c (xg_select):
4825 Prefer assignment to memcpy when either will do.
4827 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4828 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4829 time an item is removed. No need to mark this function 'inline';
4830 the compiler knows better than we do.
4832 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4834 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4835 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4836 to change_frame_size (Bug#12388).
4837 (windowDidResize:): Pass YES to updateFrameSize.
4839 * nsterm.h: Add delay parameter to updateFrameSize.
4841 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4843 Discard killed buffers from deleted window and frame objects.
4844 This reduces an amount of references to killed buffers and
4845 helps GC to reclaim them faster.
4846 * alloc.c (discard_killed_buffers): New function.
4847 (mark_object): Use it for deleted windows and frames.
4848 (mark_object): If symbol's value is set up for a killed buffer
4849 or deleted frame, restore its global binding.
4850 * data.c (swap_in_global_binding): Add GC notice.
4851 (swap_in_symval_forwarding): Use convenient set_blv_where.
4852 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4853 * window.h: ... to here.
4855 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4857 Convenient macro to check whether the buffer is live.
4858 * buffer.h (BUFFER_LIVE_P): New macro.
4859 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4860 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4862 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4864 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4865 composition cases (Bug#12364).
4867 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4868 overhang of succeeding glyphs overlapping box cursor.
4870 * w32term.c (x_draw_glyph_string): Likewise.
4872 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4874 Simplify, document, and port floating-point (Bug#12381).
4875 The porting part of this patch fixes bugs on non-IEEE platforms
4876 with frexp, ldexp, logb.
4877 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4879 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4880 support, by removing commented-out code and briefly listing the
4881 C89 functions excluded. The commented-out stuff was confusing
4882 maintenance, e.g., we thought we needed cbrt but it was commented out.
4883 (logb): Remove decl; no longer needed.
4884 (isfinite): New macro, if not already supplied.
4885 (isnan): Don't replace any existing macro.
4886 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4887 are present on all C89 platforms.
4888 (Ffrexp): Do not special-case zero, as frexp does the right thing
4890 (Flogb): Do not use logb, as it doesn't have the desired meaning
4891 on hosts that use non-base-2 floating point. Instead, stick with
4892 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4893 frexp, to avoid getting an unspecified result.
4895 * xdisp.c (Qinhibit_debug_on_message): Now static.
4897 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4899 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4900 NSBezierPath (Bug#12131).
4902 2012-09-10 Chong Yidong <cyd@gnu.org>
4904 * fns.c (Fdelq, Fdelete): Doc fix.
4906 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4908 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4909 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4911 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4913 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4914 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4917 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4919 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4920 left fringe if the window has a left margin. This avoids leaving
4921 traces of the cursor because its leftmost pixel is not drawn over.
4923 * dispnew.c (update_window_line): When the left margin area of a
4924 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4925 that screen line. (Bug#12277)
4927 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4929 Assume C89 or later for math functions (Bug#12381).
4930 This simplifies the code, and makes it a bit smaller and faster,
4931 and (most important) makes it easier to clean up signal handling
4932 since we can stop worring about floating-point exceptions in
4933 library code. That was a problem before C89, but the problem
4934 went away many years ago on all practical Emacs targets.
4935 * data.c, image.c, lread.c, print.c:
4936 Don't include <math.h>; no longer needed.
4937 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4938 might be autoconfigured, as that never happens.
4940 * doprnt.c (DBL_MAX_10_EXP):
4941 * print.c (DBL_DIG):
4942 Remove. C89 or later always defines these.
4943 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4944 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4945 (arith_error, domain_error, domain_error2):
4946 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4947 no longer needed -- we simply return what C returns. All uses removed.
4948 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4950 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4951 Remove. All uses expanded, as these macros are no longer used
4952 more than once and are now more trouble than they're worth.
4953 (Ftan): Use tan, not sin / cos.
4954 (Flogb): Assume C89 frexp.
4955 (fmod_float): Assume C89 fmod.
4956 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4957 (init_floatfns): Remove. All uses removed.
4959 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4961 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4962 compositeToPoint for OSX < 10.6 (Bug#12390).
4964 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4966 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4967 This produces more-accurate results.
4969 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4971 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4972 changes (Bug#12088).
4974 2012-09-08 Chong Yidong <cyd@gnu.org>
4976 * syntax.c (Fstring_to_syntax): Doc fix.
4978 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4980 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4981 in the internal border.
4982 (x_set_window_size): Remove static variables and their usage.
4983 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4984 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4985 Remove fringe/internal border adjustment (Bug#11052).
4986 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4987 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4988 (ns_fix_rect_ibw): Remove.
4989 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4990 (ns_dumpglyphs_box_or_relief): Ditto.
4991 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4993 (ns_dumpglyphs_image): Ditto.
4994 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4996 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4997 their usage. Add fringe_extended_p and its use as in other terms.
4998 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4999 scroll bar was removed.
5000 (updateFrameSize): New function.
5001 (windowDidResize): Move code to updateFrameSize and call it.
5003 * nsterm.h (EmacsView): Add updateFrameSize.
5005 2012-09-07 Chong Yidong <cyd@gnu.org>
5007 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5009 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5011 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5013 More signal-handler cleanup (Bug#12327).
5014 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5015 Problem introduced when merging patches. Noted by Eli Zaretskii in
5016 <http://bugs.gnu.org/12327#67>.
5017 * floatfns.c: Comment fix.
5018 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5019 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5020 and anyway the declaration is harmless even if SIGDANGER is not defined.
5021 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5022 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5023 source files not surprisingly expected syssignal.h to define, or
5024 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5025 Include <sys/ioctl.h>, for FIONREAD.
5026 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5027 This eliminates a problem whereby other files mysteriously had
5028 to include "syssignal.h" before including "systty.h" if they
5029 wanted to use "#ifdef SIGIO".
5031 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5033 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5035 * w32.c (sigemptyset): Empty the set.
5036 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5038 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5040 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5042 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5043 (mark_object): Likewise for frame objects.
5045 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5047 * syssignal.h (handle_on_main_thread): Always declare,
5048 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5049 This ports to platforms without HAVE_PTHREAD.
5051 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5053 Signal-handler cleanup (Bug#12327).
5054 Emacs's signal handlers were written in the old 4.2BSD style with
5055 sigblock and sigmask and so forth, and this led to some
5056 inefficiencies and confusion. Rewrite these to use
5057 pthread_sigmask etc. without copying signal sets around. Also,
5058 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5059 'signal', and instead use functions that do not attempt to take
5060 over the system name space. This patch causes Emacs's text
5061 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5062 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5063 Do not include <signal.h> or "syssignal.h", as these
5064 modules do not use signals.
5065 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5066 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5067 Do not include <signal.h>, as "syssignal.h" does that for us now.
5068 * atimer.c (sigmask_atimers): New function.
5069 (block_atimers, unblock_atimers): New functions,
5070 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5072 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5073 no longer needed here.
5074 * emacs.c (main): Inspect existing signal handler with sigaction,
5075 so that there's no need to block and unblock SIGHUP.
5076 * sysdep.c (struct save_signal): New member 'action', replacing
5077 old member 'handler'.
5078 (save_signal_handlers, restore_signal_handlers):
5079 Use sigaction instead of 'signal' to save and restore.
5080 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5081 New function. All users of 'signal' modified to use set_sighandler
5082 if they're writeonly, and to use sys_signal if they're read+write.
5083 (emacs_sigaction_init, forwarded_signal): New functions.
5084 (sys_signal): Remove. All uses replaced by calls to sigaction
5085 and emacs_sigaction_init, or by direct calls to 'signal'.
5086 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5087 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5088 all uses replaced by pthread_sigmask etc. calls.
5089 * syssignal.h: Include <signal.h>.
5090 (emacs_sigaction_init, forwarded_signal): New decls.
5091 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5092 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5093 (sigmask, sys_sigmask): Remove; no longer needed.
5094 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5095 (sigblock, sigunblock, sigfree):
5096 (sigsetmask) [!defined sigsetmask]:
5097 Remove. All uses replaced by pthread_sigmask.
5098 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5099 no longer need to be replaced, and its typical old uses
5100 are now done via emacs_sigaction_init and sigaction.
5101 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5102 (sys_sigdel): Remove; unused.
5103 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5105 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5107 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5108 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5110 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5112 Explicitly mark buffer_defaults and buffer_local_symbols.
5113 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5114 mark_local_symbols here.
5115 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5116 since special buffers aren't marked here any more.
5117 (allocate_buffer): Chain new buffer with all_buffers here...
5118 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5120 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5121 (syms_of_buffer): Remove staticpro of the above.
5122 (init_buffer_once): Set names for buffer_defaults and
5123 buffer_local_symbols.
5125 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5127 Use bool for booleans in font-related modules.
5128 * font.c (font_intern_prop, font_style_to_value)
5129 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5130 (generate_otf_features, font_check_otf_features, font_check_otf)
5131 (font_match_p, font_list_entities, font_at):
5132 * fontset.c (fontset_id_valid_p, reorder_font_vector
5133 (fontset_find_font, Fset_fontset_font)
5134 (face_suitable_for_char_p) [0]:
5135 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5136 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5137 (m17n_flt_initialized, ftfont_shape_by_flt):
5138 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5139 * nsfont.m (nsfont_draw):
5140 * w32font.c (w32font_draw):
5141 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5142 Use bool for booleans.
5143 * font.h: Adjust to above API changes.
5144 (struct font, struct font_driver, struct font_driver_list):
5145 Use bool for booleans.
5146 (struct font): Remove useless member encoding_type.
5148 * fontset.c, xftfont.c: Omit unnecessary static decls.
5150 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5152 * alloc.c (mark_object): Revert window marking code
5153 since it's unsafe for the Fset_window_configuration.
5155 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5157 Fix race conditions with signal handlers and errno (Bug#12327).
5158 Be more systematic about preserving errno whenever a signal
5159 handler returns, even if it's not in the main thread. Do this by
5160 renaming signal handlers to distinguish between signal delivery
5161 and signal handling. All uses changed.
5162 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5163 * data.c (deliver_arith_signal): Rename from arith_error.
5164 * dispnew.c (deliver_window_change_signal): Rename from
5165 window_change_signal.
5166 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5167 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5168 * keyboard.c (deliver_input_available_signal): Rename from
5169 input_available_signal.
5170 (deliver_user_signal): Rename from handle_user_signal.
5171 (deliver_interrupt_signal): Rename from interrupt_signal.
5172 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5173 (deliver_child_signal): Rename from sigchld_handler.
5174 * atimer.c (handle_alarm_signal):
5175 * data.c (handle_arith_signal):
5176 * dispnew.c (handle_window_change_signal):
5177 * emacs.c (handle_fatal_signal, handle_danger_signal):
5178 * keyboard.c (handle_input_available_signal):
5179 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5180 * process.c (handle_pipe_signal, handle_child_signal):
5181 New functions, with the actual signal-handling code taken from the
5182 original respective signal handlers, sans the sporadic attempts to
5183 preserve errno, since that's now done by handle_on_main_thread.
5184 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5185 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5186 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5188 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5189 Move initialization of main_thread to sysdep.c's init_signals.
5190 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5191 our usage, and simplifies the mainline code.
5192 (record_child_status_change): New static function, as a helper
5193 for handle_child_signal, and with most of the old child handler's
5195 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5196 (handle_child_signal): Use the above.
5197 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5198 Moved here from emacs.c.
5199 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5200 code moved here from emacs.c's main function.
5201 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5202 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5203 This lets callers save and restore errno properly.
5205 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5207 Remove redundant or unused things here and there.
5208 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5209 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5210 * editfns.c (Fcompare_buffer_substrings): Likewise.
5211 * frame.h (struct terminal, struct font_driver_list):
5212 Remove redundant declarations.
5213 * window.h (Qleft, Qright): Likewise.
5215 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5217 Do not mark objects from deleted buffers, windows and frames.
5218 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5219 (mark_object): Likewise for windows and frames.
5221 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5223 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5224 buffer_defaults and buffer_local_symbols as valid objects.
5225 Return special value to denote them.
5227 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5229 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5230 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5231 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5232 (file_name_absolute_p, Fsubstitute_in_file_name):
5233 (check_executable, check_writable, Ffile_accessible_directory_p)
5234 (Fset_file_selinux_context, Fdefault_file_modes)
5235 (Finsert_file_contents, choose_write_coding_system)
5236 (Fwrite_region, build_annotations, a_write, e_write)
5238 * filelock.c (boot_time_initialized, get_boot_time)
5239 (get_boot_time_1, lock_file_1, within_one_second):
5240 * floatfns.c (in_float):
5241 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5242 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5243 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5244 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5245 * window.c (compare_window_configurations):
5246 Use bool for booleans.
5247 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5248 (Fdefault_file_modes): Now mode_t, not int, for modes.
5249 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5250 (internal_delete_file): Now returns void, not a (boolean) int,
5251 since nobody was looking at the return value.
5252 * lisp.h, window.h: Adjust to above API changes.
5254 * xdisp.c (set_message): Simplify and reindent last change.
5256 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5258 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5260 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5262 * eval.c (call_debugger): Make the function non-static so that we
5263 can call it from set_message.
5265 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5266 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5268 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5270 Give more-useful info on a fatal error (Bug#12328).
5271 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5272 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5273 of doing the work ourselves.
5274 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5275 do most of the work.
5276 (fatal_error_backtrace): New function, taken from the guts
5277 of the old fatal_error_signal, but with a new option to output
5279 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5280 info about the signal than just its number.
5281 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5282 * sysdep.c: Include <execinfo.h>
5283 (emacs_backtrace): New function, taken partly from the previous
5284 code of the 'die' function.
5285 (emacs_abort): Call fatal_error_backtrace rather than abort.
5287 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5289 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5290 eager (load-time) macro-expansion.
5291 * lisp.mk (lisp): Add macroexp.
5293 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5295 Simplify redefinition of 'abort' (Bug#12316).
5296 Do not try to redefine the 'abort' function. Instead, redo
5297 the code so that it calls 'emacs_abort' rather than 'abort'.
5298 This removes the need for the NO_ABORT configure-time macro
5299 and makes it easier to change the abort code to do a backtrace.
5300 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5301 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5302 Remove; sysdep.c's emacs_abort now takes its place.
5303 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5304 'abort' changed to use 'emacs_abort'.
5305 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5306 (abort) [!defined abort]: Rename to ...
5307 (emacs_abort): ... new name.
5308 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5309 the place of the old 'abort' in emacs.c.
5310 * w32.c, w32fns.c (abort): Do not #undef.
5311 * w32.c (emacs_abort): Rename from w32_abort.
5313 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5315 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5316 offsets[j].dv, since the y axis of the screen coordinates points
5317 down, while the y axis of the font definition coordinates points
5318 up. This fixes display of Arabic diacritics such as KASRA and
5319 KASRATAN. (Bug#11860)
5321 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5323 Be more systematic about _setjmp vs setjmp.
5324 * alloc.c (test_setjmp, mark_stack):
5325 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5326 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5327 (png_load, my_error_exit, jpeg_load):
5328 * process.c (send_process_trap, send_process):
5329 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5330 The underscored versions are up to 30x faster on some hosts.
5331 Formerly, the code used setjmp+longjmp sometimes and
5332 _setjmp+_longjmp at other times, with no particular reason to
5333 prefer setjmp+longjmp.
5335 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5337 Fix minor problem found by static checking.
5338 * buffer.c (Fdelete_all_overlays): Return nil.
5340 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5342 * buffer.c (Fdelete_all_overlays): New function.
5344 2012-09-03 Chong Yidong <cyd@gnu.org>
5346 * gtkutil.c: Add extern decl for Qxft.
5348 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5350 * emacs.c, eval.c: Use bool for boolean.
5351 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5352 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5353 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5354 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)

5357 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
5358 (maybe_call_debugger, Fbacktrace):
5359 * process.c (read_process_output, exec_sentinel):
5360 Use bool for booleans.
5361 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5362 All callers changed.
5363 * eval.c (interactive_p): Omit always-true boolean argument
5364 EXCLUDE_SUBRS_P. All callers changed.
5365 * dispextern.h, lisp.h: Reflect above API changes.
5366 * firstfile.c (dummy): Use the address of 'main', whose signature
5367 won't change, instead of the address of 'initialize', whose
5368 signature just changed from int to bool.
5369 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5370 * msdos.c (fatal_error_in_progress): ... from here.
5371 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5373 (redisplay_internal, unwind_redisplay): Simply clear
5374 REDISPLAYING_P when unwinding, instead of saving its previous,
5375 always-false value and then restoring it.
5377 Clean up some extern decls.
5378 Mostly, this hoists extern decls out of .c files and into .h files.
5379 That way, we're more likely to catch errors if the interfaces change.
5380 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5381 declare xg_mark_data.
5382 * dispextern.h (x_frame_parm_handlers):
5384 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5385 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
5386 (Qultra_bold, Qoblique, Qitalic):
5387 Move extern decl here from .c file.
5388 * alloc.c (xg_mark_data) [USE_GTK]:
5390 * eval.c (Qlexical_binding):
5391 * fns.c (time) [!HAVE_UNISTD_H]:

5397 * process.c (QCfamily, QCfilter):
5398 * widget.c (free_frame_faces):

5400 * xfont.c (x_clear_errors):
5401 * xterm.c (x_frame_parm_handlers):
5402 Remove now-redundant extern decls.
5403 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5404 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5406 * xfaces.c: Remove unnecessary static decls.
5407 * xterm.c (updating_frame): Remove decl of nonexistent object.
5409 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5410 when building globals.h, as the objects that are not built on
5411 this host are not needed to compile C files on this host.
5413 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5415 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
5417 * frame.h: Add missing prototype for x_wm_set_size_hint.
5419 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

5444 Use bool for boolean.
5445 * intervals.h, lisp.h, systime.h: Reflect above API changes.
5446 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
5448 2012-09-02 Chong Yidong <cyd@gnu.org>
5450 * keymap.c (push_key_description): Print M-TAB as C-M-i
5453 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5455 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

5465 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5466 more than one grapheme cluster passed to the shaper: compute the
5467 offset adjustment values separately for each cluster. (Bug#11860)
5469 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5470 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5471 about implicit conversions from integer to pointer.
5473 2012-09-01 Daniel Colascione <dancol@dancol.org>
5475 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

5491 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
5492 x_wm_set_size_hint, x_query_colors, x_real_positions,
5493 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
5494 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
5495 all of which have been moved to common code.
5497 * xfaces.c: Include TERM_HEADER instead of listing all possible
5498 window-system headers.
5500 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

5521 * keyboard.c: Include TERM_HEADER instead of listing all possible
5522 window-system headers.
5524 * image.c: Include TERM_HEADER instead of listing all possible
5525 window-system headers. Declare Vlibrary_cache when compiling for
5528 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
5529 window system declarations.
5531 * frame.h: Move common functions here: set_frame_menubar,
5532 x_set_window_size, x_sync, x_get_focus_frame,
5533 x_set_mouse_position, x_set_mouse_pixel_position,
5534 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,
5535 x_char_width, x_char_height, x_pixel_width, x_pixel_height,
5536 x_set_frame_alpha, x_set_menu_bar_lines, x_set_tool_bar_lines,
5537 x_activate_menubar, x_real_positions, x_bitmap_icon,
5538 x_set_menu_bar_lines, free_frame_menubar, x_free_frame_resources,
5541 * frame.c: Include TERM_HEADER instead of listing all possible
5542 window-system headers.
5544 * font.c: Include TERM_HEADER instead of listing all possible
5545 window-system headers.
5547 * emacs.c: Include TERM_HEADER.
5549 * dispnew.c: Include TERM_HEADER instead of listing all possible
5550 window-system headers.

5554 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
5555 the current window system; include in list of objects to link into
5558 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5560 Remove mark_ttys function and fix tty_display_info initialization.
5561 * lisp.h (mark_ttys): Remove prototype.
5562 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5563 to mark_ttys because all possible values of 'top_frame' slot are
5564 the frames which are reachable from Vframe_list.
5565 * term.c (mark_ttys): Remove.
5566 (init_tty): Safely initialize 'top_frame' slot with Qnil.
5568 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5570 Change struct frame bitfields from unsigned char to unsigned.
5571 * frame.h (struct frame): Change type of 'display_preempted',

5585 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
5586 does not become zero (Bug#12234).
5588 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
5590 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
5591 for GCC 4.7.1 x86-64.
5593 2012-08-30 Glenn Morris <rgm@gnu.org>
5595 * lread.c (init_lread): For out-of-tree builds, only add the
5596 source directory's site-lisp dir to the load-path if it exists,
5597 consistent with in-tree builds. (Bug#12302)
5599 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
5601 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

5612 (clicked:): Remove return self, declare return value as void.
5613 Set dialog_return to button_values[seltag]. Code formatting change.
5614 (initFromContents:isQuestion:): Adjust call to process_dialog.
5615 Code formatting change.
5616 (timeout_handler:): Set timer_fired to YES.
5617 (runDialogAt:): Set timer_fired to NO.
5618 Handle click on close button as quit.
5620 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5621 Add window_closed and button_values. Add void as return value for
5622 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5623 Add process_dialog as new member.
5625 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5627 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
5628 is not one of the heaps we manage. (Bug#12242)
5630 2012-08-28 Glenn Morris <rgm@gnu.org>
5632 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

5688 (change_frame_size_1, sit_for):
5689 Use bool for boolean.
5690 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
5691 and remove last int (actually boolean) argument, which was always 0.
5692 All callers changed.

5694 * dispextern.h (struct composition_it): Use bool for boolean.
5695 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
5696 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
5697 * dired.c (file_name_completion):
5698 Use bool for boolean. (This was missed in an earlier change.)
5700 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5702 * window.c (Fset_window_configuration): Revert first part of
5705 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>

5730 Use bool for booleans.
5731 * dired.c (file_name_completion):
5732 * process.h (fd_callback):
5733 Omit int (actually boolean) argument. It wasn't being used.

5763 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5764 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5765 not a boolean 'int', since callers never look at the return value.
5766 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5767 * coding.h (decoding_buffer_size, encoding_buffer_size)
5768 (emacs_mule_string_char): Remove unused extern decls.
5769 (struct iso_2022_spec, struct coding_system):

5785 buffer doesn't appear in the selected window, go to its old
5788 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5790 Special MEM_TYPE_SPARE to denote reserved memory.
5791 * alloc.c (enum mem_type): New memory type.
5792 (refill_memory_reserve): Use new type for spare memory.

5822 (map_sub_char_table):
5823 Use bool for boolean.
5824 * character.c (str_to_unibyte): Omit last boolean argument; it was
5825 always 0. All callers changed.
5826 * character.h, charset.h: Adjust to match previous changes.
5827 * character.h (char_printable_p): Remove decl of nonexistent function.
5828 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5829 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5830 are all boolean, so make them single-bit bitfields.
5832 * lisp.h (ASET): Remove attempt to detect side effects.
5833 It was meant to be temporary and it often doesn't work,
5834 because when IDX has side effects the behavior of IDX==IDX
5835 is undefined. See Stefan Monnier in
5836 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5838 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5840 * lisp.h (functionp): New function (extracted from Ffunctionp).
5841 (FUNCTIONP): Use it.
5842 * eval.c (Ffunctionp): Use it.
5844 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5846 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5847 as that's faster and simpler than static storage. Don't bother
5848 with the g_main_context_query overhead if g_main_context_pending
5849 says no events are pending.
5850 (gfds, gfds_size): Remove these static vars.
5851 (xgselect_initialize): Remove; no longer needed.
5852 All uses and decls removed.
5854 * emacs.c (fatal_error_signal_hook): Remove.
5855 All uses removed. This leftover from old code was always 0.
5857 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5858 * casefiddle.c (casify_object, casify_region):
5859 * casetab.c (set_case_table):

5864 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5866 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.

5870 On assertion failure, print backtrace if available.
5871 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.

5881 * lisp.h (USE_SAFE_ALLOCA):
5882 Use bool for booleans, instead of int.
5883 * lisp.h, process.h: Adjust prototypes to match above changes.
5884 * callint.c (Fcall_interactively): Don't assume the mark's
5885 offset fits in 'int'.
5887 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5889 * buffer.c, buffer.h: Use bool for boolean.

5896 (mmap_enlarge, mmap_set_vars):
5897 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5898 Use bool for booleans, instead of int.
5899 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5900 since the 1-or-0 return value is always ignored anyway.
5901 (mmap_initialized_p):
5902 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5903 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5905 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5907 * bidi.c: Use bool for boolean.
5908 This is a bit more readable, and makes the text segment of bidi.o
5909 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5910 Presumably it's faster too.

5917 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5918 Use bool for booleans, instead of int.
5919 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5920 (bidi_unshelve_cache): Adjust decls to match code.
5922 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5924 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5927 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5929 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5930 * atimer.h: Include <stdbool.h>.
5932 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5934 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5935 compile time tests instead of run time tests on systems that do
5937 (FRAME_MAC_P): Remove leftover from deleted code.
5938 * frame.c (syms_of_frame): Remove leftover from deleted code.
5940 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5942 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5944 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5946 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5947 Otherwise, the compiler complains about (A?B:C) where B is void
5948 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5949 (fontset_add): Return void, for FONTSET_ADD.
5951 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5953 * alloc.c: Use bool for booleans.
5954 (gc_in_progress, abort_on_gc)
5955 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5956 (dont_register_blocks) [GC_MALLOC_CHECK]:
5957 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5958 (check_string_bytes, make_specified_string, memory_full)
5959 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5960 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5961 (mark_stack, valid_pointer_p, make_pure_string)
5962 (Fgarbage_collect, survives_gc_p, gc_sweep):
5963 Use bool for booleans, instead of int.
5964 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5965 Remove unused local.
5966 * alloc.c (PURE_POINTER_P):
5967 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5968 * editfns.c (Fformat):
5969 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5971 * fns.c (sweep_weak_table):
5972 * lisp.h (suppress_checking, push_message, survives_gc_p)
5973 (make_pure_string, gc_in_progress, abort_on_gc):
5974 * lread.c (readchar, read1):
5975 * print.c (Fprin1_to_string):
5976 * xdisp.c (push_message):
5977 Use bool for booleans affected directly or indirectly by
5980 Make recently-introduced setters macros.
5981 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5982 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5983 (set_fontset_default, set_fontset_fallback): Rename from their
5984 upper-case counterparts, and make them functions rather than macros.
5985 This is more consistent with the other recently-introduced setters.
5986 These don't need to be inline, since they're local.
5988 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5990 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5991 the loop (Bug#12247).
5993 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5995 * lisp.h (vcopy): Use memcpy rather than our own loop.
5996 This fixes a performance regression introduced by the recent
5997 addition of vcopy. This means 'vcopy' will need to be modified
5998 for a copying collector, but that's OK. Also, tighten the
5999 checking in the assertion.
6001 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6003 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6004 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6005 non-base glyph for the width of the base character, according to
6006 what x_draw_composite_glyph_string_foreground expects.
6007 Generate WADJUST value according to composition_gstring_width's
6008 expectations, to produce correct width of the composed character.
6009 Reverse the sign of the DU offset produced by ScriptPlace.
6011 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6013 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6015 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6017 Avoid direct writes to contents member of struct Lisp_Vector.
6018 * lisp.h (vcopy): New function to copy data into vector.
6019 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6020 * fns.c (Ffillarray): Use ASET.
6021 * keyboard.c (timer_check_2): Use AREF and ASET.
6022 (append_tool_bar_item, Frecent_keys): Use vcopy.
6023 * lread.c (read_vector): Use ASET.
6024 * msdos.c (Frecent_doskeys): Use vcopy.
6025 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6026 (Finternal_merge_in_global_face): Use ASET and vcopy.
6027 * xfont.c (xfont_list_pattern): Likewise.

6032 the position of its buffer's point.
6033 (Fset_window_point): For the selected window always go in its
6034 buffer to the specified position.
6036 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6038 Setter macros for fontsets.
6039 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6040 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6041 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6044 2012-08-20 Glenn Morris <rgm@gnu.org>
6046 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6047 Don't assume that `ln -f' works.
6049 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6051 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6052 and later about non-assignments with no effect. See discussion at
6053 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6056 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6058 Inline setter functions for Lisp_Objects slots of struct specbinding.
6059 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6062 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6064 * window.c (select_window): Always make selected window's buffer
6067 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6069 Use AREF and ASET for docstrings of category tables.
6070 * category.h (CATEGORY_DOCSTRING): Use AREF.
6071 (SET_CATEGORY_DOCSTRING): Use ASET.
6072 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6074 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6076 Inline setter functions for hash table members.
6077 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6078 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6079 (set_hash_key_and_value, set_hash_index, set_hash_next)
6080 (set_hash_hash): New functions.
6081 * charset.c, fns.c: Adjust users.
6083 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6085 Inline getter and setter functions for per-buffer values.
6086 * buffer.h (per_buffer_default, set_per_buffer_default)
6087 (per_buffer_value, set_per_buffer_value): New functions.
6088 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6089 * buffer.c, data.c: Adjust users.
6091 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6093 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6095 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6097 Rely on <config.h> + <unistd.h> to declare 'environ',
6098 as gnulib does this if the system doesn't.
6099 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6100 Remove declaration. MS-Windows declares it on stdlib.h which is
6101 included by conf_post.h.
6102 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6103 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6104 * vm-limit.c: Include <unistd.h>, for 'environ'.
6106 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6107 (start_of_data): Remove decl; mem-limits.h provides it.
6109 * xdisp.c (handle_invisible_prop): Make it a bit faster
6110 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6112 2012-08-19 Chong Yidong <cyd@gnu.org>
6114 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6117 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6119 * .gdbinit: Use call instead of set when calling a function in the
6122 * data.c (set_internal): Don't use set_blv_found.
6123 (Fkill_local_variable): Likewise.
6125 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6127 * nsfont.m (ns_ascii_average_width): Ensure the string
6128 ascii_printable is initialized with a null-terminated character
6129 array. Otherwise, it can contain undesired extra characters.
6131 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6133 port new setting code to Sun C 5.8 2005/10/13
6134 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6135 Return void, not Lisp_Object. Otherwise, the compiler
6136 complains about (A?B:C) where B is void and C is Lisp_Object
6137 when compiling CHAR_TABLE_SET, due to the recent change to
6138 the API of sub_char_table_set_contents.
6140 2012-08-18 Chong Yidong <cyd@gnu.org>
6142 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
6143 for the string case (Bug#3874).

6298 The old version was confusing because it used the same name
6299 'parent' for two different things.
6301 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
6303 Functions to get and set Lisp_Object fields of buffer-local variables.

6312 font spec, make the font's attributes take precedence over
6313 directly-specified attributes.
6314 (merge_face_ref): Recognize :font.
6316 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

6970 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6971 * w32.c (init_environment): Change the default values of many
6972 environment variables in dflt_envvars[] to NULL, to avoid pushing
6973 them into environment when they were not already defined.
6974 Remove the code that deletes site-lisp subdirectories from the default
6975 value of EMACSLOADPATH, as it is no longer needed.
6976 (check_windows_init_file): Now external, not static.
6977 Use Vload_path as is, without adding anything, as this function is now
6978 called when Vload_path is already set up.
6980 * w32.h (check_windows_init_file): Add prototype.
6982 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6989 installation tree, as appropriate.
6991 * callproc.c (init_callproc_1): Call decode_env_path instead of
6992 doing its equivalent by hand.

6994 the code that sets Vexec_path run on MS-Windows.
6996 * lread.c (init_lread): Add comments to #ifdef's.
6998 * msdos.c (dos_set_window_size, IT_update_begin)

7025 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7026 Remove unnecessary pointer casts.
7027 * alloc.c (record_xmalloc): New function.
7028 * lisp.h (record_xmalloc): New decl.
7029 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7030 more like a function. This is because the pointer cast is not
7031 needed. All uses changed.
7032 * print.c (print_string, print_error_message): Avoid length recalc.
7034 Improve fix for macroexp crash with debugging (Bug#12118).
7035 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7036 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7037 not supposed to be invoked from the garbage collector.

7039 (gc_aset): New function, which is like ASET but can be
7040 used in the garbage collector.

7069 with addition of handling of symlinks and support for 'lstat'.
7070 If possible, get file's attributes and security information by
7071 handle, not by name. Produce S_IFLNK bit for symlinks, when
7072 called from 'lstat'.
7073 (stat, lstat): New functions, call 'stat_worker'.
7074 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7075 symlinks when the underlying filesystem supports them.
7077 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7079 Fix macroexp crash on Windows with debugging (Bug#12118).
7080 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7081 checking subscripts; problem introduced with the recent
7082 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7083 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7084 since it's used in non-static inline functions now.
7086 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7087 Don't assume buffer size fits in 'int'. Remove unused local.

7105 * character.c (CHARACTER_INLINE):
7106 * charset.c (CHARSET_INLINE):
7107 * composite.c (COMPOSITE_INLINE):
7108 * dispnew.c (DISPEXTERN_INLINE):
7109 * sysdep.c (SYSTIME_INLINE):
7110 Define to EXTERN_INLINE, so that the corresponding functions
7111 are compiled into code.
7112 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7113 (INLINE_HEADER_END): New macros.
7114 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7134 hard-coding the path separator.
7136 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7138 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7139 This how ASET and AREF are supposed to work, and makes
7140 it easier to think about future improvements. See
7141 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7142 * charset.h (set_charset_attr): New function.

7523 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
7524 (w32_kbd_patch_key, key_event): Use the codepage returned by
7525 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

7632 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7633 emacs.c, as this is a more-suitable home. Had this been done earlier
7634 the fix for 12036 would have avoided some of the problems noted in
7635 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7636 would have been more obvious.
7637 * emacs.c: Do not include <verify.h>; no longer needed.

7646 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7647 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7648 not be usable in #if. This simplifies things.
7650 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7652 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7657 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7658 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7659 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7660 Adjust to changes in lisp.h and emacs.c, by using

7663 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

7665 instead of gdb_valbits.
7666 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7667 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7668 instead of gdb_array_mark_flag.
7669 (xboolvector): Get size from $->size, not $->header.size.

8575 Avoid the need for strncpy, by using build_string or
8576 make_unibyte_string directly. Use dtoastr, not snprintf.
8577 * process.c (Fmake_network_process): Diagnose service names that
8578 are too long, rather than silently truncating them or creating
8579 non-null-terminated names.
8580 (Fnetwork_interface_info): Likewise, for interface names.
8581 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8582 Prefer sprintf to strncat.
8583 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
8584 Prefer vsnprintf to vsprintf + strncpy.

8609 Optimize pure C strings initialization.
8610 * lisp.h (make_pure_string): Fix prototype.
8611 (build_pure_c_string): New function, defined as static inline. This
8612 provides a better opportunity to optimize away calls to strlen when
8613 the function is called with compile-time constant argument.
8614 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8615 argument, adjust users accordingly. Use build_pure_c_string where
8617 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8618 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8619 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8621 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8623 Avoid calls to strlen in miscellaneous functions.
8624 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8625 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8626 * lread.c (openp): Likewise.
8628 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8630 Avoid calls to strlen in path processing functions.
8631 * fileio.c (file_name_as_directory): Add comment. Change to add
8632 srclen argument and return the length of result. Adjust users
8634 (directory_file_name): Fix comment. Change to add srclen argument,
8635 swap 1st and 2nd arguments to obey the common convention.
8636 Adjust users accordingly.
8637 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8639 2012-07-10 Glenn Morris <rgm@gnu.org>
8641 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:

8646 * s/gnu.h (DATA_START): Move definitions to configure.
8648 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8649 We include usg5-4-common.h, which defines them both.
8651 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8652 O_RDONLY already includes it).
8654 Stop ns builds setting the EMACSLOADPATH environment variable.
8655 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8656 Now it does not set EMACSLOADPATH, just returns the load-path string.
8657 * nsterm.h: Update accordingly.
8658 * lread.c [HAVE_NS]: Include nsterm.h.
8659 (init_lread) [HAVE_NS]: Use ns_load_path.

8662 2012-07-09 Glenn Morris <rgm@gnu.org>
8664 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8665 since the included bsd-common.h does so.
8667 Stop ns builds setting the EMACSPATH environment variable.
8668 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8669 (ns_init_paths): Do not set EMACSPATH.
8670 * nsterm.h (ns_exec_path): Add it.
8671 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8674 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8676 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8678 * process.c (wait_reading_process_output): 'waitchannels' was unset
8679 when read_kbd || !NILP (wait_for_cell); fix this.
8681 Add GCC-style 'const' attribute to functions that can use it.
8682 * character.h (char_resolve_modifier_mask):
8683 * keyboard.h (make_ctrl_char):
8684 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

8691 Declare the dummy function with ATTRIBUTE_CONST.
8692 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8693 Add decls with ATTRIBUTE_CONST.
8695 Minor improvements to make_formatted_string.
8696 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8697 where int is good enough, as vsprintf returns an int.
8698 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8700 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8702 Use make_formatted_string to avoid double length calculation.
8703 * lisp.h (make_formatted_string): New prototype.
8704 * alloc.c (make_formatted_string): New function.
8705 * buffer.c (Fgenerate_new_buffer_name): Use it.
8706 * dbusbind.c (syms_of_dbusbind): Likewise.

8709 * frame.c (make_terminal_frame, set_term_frame_name)
8710 (x_report_frame_params): Likewise.
8711 * image.c (gs_load): Likewise.
8712 * minibuf.c (get_minibuffer): Likewise.

8727 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8729 Move marker debugging code under MARKER_DEBUG.
8730 * marker.c (MARKER_DEBUG): Move marker debugging code under
8731 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8732 for bootstrap with --enable-checking (~3x slowdown reported
8733 by Juanma Barranquero <lekktu@gmail.com>).
8734 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8736 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8738 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8739 See <http://bugs.gnu.org/11825#29>.
8741 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8743 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8744 has no font, use the frame's font. (Bug#11813)
8745 (display_line): Add commentary about displaying truncation glyphs
8747 (produce_special_glyphs): Move here from term.c.
8749 * term.c (produce_special_glyphs): Move to xdisp.c.
8751 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8754 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8756 * xdisp.c (display_line): Avoid warning about implicit declaration
8759 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8761 * lisp.h: Remove empty conditional.
8763 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8765 * lread.c (load_path_check): Now static.
8767 Fix some minor --with-ns problems found by static checking.
8768 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8769 (x_set_font) [!HAVE_X_WINDOWS]:
8770 * image.c (xpm_load_image) [HAVE_NS]:
8771 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8772 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8773 Remove unused local.
8774 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8775 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8776 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8777 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8778 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8779 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8780 Fix pointer signedness problem.
8781 * xfaces.c (FRAME_X_FONT_TABLE):
8782 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8784 2012-07-07 Glenn Morris <rgm@gnu.org>
8786 * lread.c (load_path_check): New function, split from init_lread.
8787 (init_lread): Reorganize. Motivation:
8788 If EMACSLOADPATH is set, check/warn about that rather than the
8789 defaults, which we are not going to use. Hence we can remove
8790 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8791 Don't warn if site-lisp directories are missing.
8792 If not installed, start from a blank load-path, since
8793 PATH_LOADSEARCH refers to the eventual installation directories.
8795 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8797 Support truncation and continuation glyphs on GUI frames, when
8798 fringes are disabled. (Bug#11832)
8799 * xdisp.c (init_iterator): Get dimensions of truncation and
8800 continuation glyphs even if on GUI frames.
8801 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8802 or both, are absent.
8803 (start_display, move_it_in_display_line_to): Handle the case of a
8804 GUI frame without a fringe to display continuation or truncation
8806 (insert_left_trunc_glyphs): Support GUI frames: make sure
8807 truncation glyphs overwrite enough glyphs from the current line to
8808 have sufficient space in pixels.
8809 (display_line): Support truncation and continuation glyphs on GUI
8810 frames. If some spare pixels are left on the line after inserting
8811 the truncation glyphs, fill that space with a stretch glyph of a
8812 suitably computed width.
8814 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8815 produce_glyphs, to support GUI sessions.
8817 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8819 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8821 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8823 Do not require float-time's arg to fit in time_t (Bug#11825).
8824 This works better on hosts where time_t is unsigned, and where
8825 float-time is applied to the (negative) difference between two times.
8826 * editfns.c (decode_time_components): Last arg is now double *,
8827 not int *, and means to store all the result as a double, without
8828 worrying about whether the seconds part fits in time_t.
8829 All callers changed.
8830 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8831 All callers changed.
8832 (Ffloat_time): Do not fail merely because the specified time falls
8833 outside of time_t range.
8835 2012-07-07 Glenn Morris <rgm@gnu.org>
8837 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8843 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8844 Update dependencies.
8846 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8848 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8850 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

8852 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8853 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8854 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
8855 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
8857 * xfont.c (compare_font_names): Redo to omit the need for casts.
8859 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8861 * xfns.c (Fx_change_window_property): Doc fix.
8862 * w32fns.c (Fx_change_window_property): Doc fix.
8864 * w32fns.c (Fx_window_property): Accept the same arguments as the
8865 X Windows version. Doc fix.
8866 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8868 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8869 Eli Zaretskii <eliz@gnu.org>
8871 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8872 Windows-specific code from nt/config.nt moved here.
8873 Obsolete settings removed.
8875 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8877 * process.c: Avoid unnecessary calls to gettime.
8878 (wait_reading_process_output): Don't get the time of day
8879 when gobbling data immediately and not waiting, as there's no need
8880 for it in that case. This removes a FIXME.
8882 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8884 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8885 is defined (Bug#11768).
8887 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8889 Fix marker debugging code.
8890 * marker.c (byte_char_debug_check): Do not perform the check
8891 if buffer is not multibyte.
8892 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8893 Call byte_char_debug_check with correct arguments.
8895 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8897 Compile marker debugging code only if ENABLE_CHECKING is defined.
8898 * marker.c (byte_char_debug_check, count_markers):
8899 Use only if ENABLE_CHECKING is defined.
8900 (byte_debug_flag): Remove.
8901 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8902 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8904 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8906 Avoid code repetition in marker-related functions.
8907 * marker.c (attach_marker): New function.
8908 (Fset_marker, set_marker_restricted, set_marker_both)
8909 (set_marker_restricted_both): Use it.
8910 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8911 Consistently rename charno to charpos.
8912 (marker_position): Add eassert.
8913 (marker_byte_position): Convert to eassert.

8932 * window.c (save_window_save): Likewise.
8934 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8936 Do not use Fdelete_overlay in delete_all_overlays
8937 to avoid redundant calls to unchain_overlay.
8938 * buffer.c (drop_overlay): New function.
8939 (delete_all_overlays, Fdelete_overlay): Use it.
8940 * minibuf.c (get_minibuffer): Fix comment.
8942 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8944 Port to OpenBSD 5.1 amd64.
8945 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8946 This is needed for OpenBSD, and should be harmless on all BSD systems.
8947 Also, include <sys/sysctl.h>, as it should be available on all
8948 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8949 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8950 use p_pid member, not kp_proc.pid.
8952 2012-07-06 Glenn Morris <rgm@gnu.org>
8954 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8956 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8958 More xmalloc and related cleanup.
8959 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
8960 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

8967 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8969 Omit needless casts involving void * pointers and allocation.
8970 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8971 as the former is more robust if P's type is changed.
8972 Prefer xzalloc to xmalloc + memset 0.
8973 Simplify malloc-or-realloc to realloc.
8974 Don't worry about xmalloc returning a null pointer.
8975 Prefer xstrdup to xmalloc + strcpy.
8976 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8978 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8979 alloca of a constant.
8981 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8983 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8984 hscroll is larger than the line width. Fixes long and futile
8985 looping inside extend_face_to_end_of_line (on a TTY) producing
8986 glyphs that are not needed and thrown away.
8988 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8990 * marker.c (set_marker_restricted_both): Simplify by using
8993 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

9016 * xdisp.c (window_hscroll_limited): New function.
9017 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9018 coordinates when window's hscroll is set to insanely large
9021 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9023 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
9024 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
9026 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9029 * lisp.h (xzalloc): New prototype. Omit needless casts.

9084 * fileio.c (time_error_value): Check the right error number.
9085 Problem reported by Troels Nielsen in
9086 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9088 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9090 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9091 This should be fixed in a better way; see Eli Zaretskii in
9092 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9093 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9095 * fileio.c (time_error_value): Rename from special_mtime.
9096 The old name's problems were noted by Eli Zaretskii in
9097 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9099 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9100 This variable's comment says Emacs needs at least one GDB-visible
9101 symbol of type enum pvec_type, to work around GDB problems.
9102 The symbol's value doesn't matter.
9104 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9105 that causes compilation to fail on pre-C99 compilers.
9107 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9109 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9110 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9112 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9114 * buffer.c (init_buffer_once): Fix initialization of
9115 headers for buffer_defaults and buffer_local_symbols.
9116 Reported by Juanma Barranquero <lekktu@gmail.com>.
9118 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9120 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9121 * lisp.h (enum pvec_type): Use fewer bits.
9122 (PSEUDOVECTOR_SIZE_BITS): New constant.
9123 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9124 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9125 change in pvec_type.
9126 (PSEUDOVECTOR_TYPEP): New macro.
9127 (TYPED_PSEUDOVECTORP): Use it.
9128 * fns.c (internal_equal): Adapt code to extract pvectype.
9129 * emacs.c (gdb_pvec_type): Update type.
9130 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9131 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9132 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9133 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9134 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9135 abusing vector->header.next.nbytes.
9136 (live_vector_p): Use PVEC_TYPE.
9137 (mark_object): Adapt code to extract pvectype. Use switch.
9139 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9141 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9142 Tighten new eassert a bit.
9144 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9146 Fix compilation with --enable-gcc-warnings and -O1
9148 * doprnt.c (doprnt): Change type of tem to int, initialize
9149 to avoid compiler warning. Add eassert.
9150 * search.c (simple_search): Initialize match_byte to avoid
9151 compiler warning. Add eassert.
9153 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9155 Avoid weird behavior with large horizontal scrolls.
9156 Without this change, for example, large hscroll values would
9157 mess up Emacs's display on Fedora 15 x86, presumably due to
9158 overflows in int calculations in the display code.
9159 Also, if buffers had long lines, Emacs would freeze.
9160 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9161 (set_window_hscroll): New function, containing the old guts of
9162 Fset_window_hscroll. Return the clipped value.
9163 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9164 This avoids the need to check against PTRDIFF_MAX.
9166 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9168 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9170 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9172 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9174 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9175 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9176 since GCC 4.4.6 issues a bogus warning for them.
9178 Fix bugs in file timestamp newness comparisons.
9179 * fileio.c (Ffile_newer_than_file_p):
9180 * lread.c (Fload): Use full timestamp resolution of files,
9181 not just the 1-second resolution, so that files that are only
9182 slightly newer still count as newer.
9183 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9184 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9186 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9188 * fileio.c: Improve handling of file time marker. (Bug#11852)
9189 (special_mtime): New function.
9190 (Finsert_file_contents, Fverify_visited_file_modtime):
9191 Use it to set special mtime values consistently.
9193 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9195 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9196 marker for non-existing file. (Bug#11852)
9198 2012-07-03 Glenn Morris <rgm@gnu.org>
9200 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9201 and did not make it into globals.h).
9203 2012-07-03 Tom Tromey <tromey@redhat.com>
9205 * window.c (Fset_window_margins, Fset_window_fringes)
9206 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
9207 * textprop.c (Fprevious_property_change): No longer static.
9208 * syntax.c (Fsyntax_table_p): No longer static.
9209 * process.c (Fget_process, Fprocess_datagram_address): No longer

9225 * callproc.c (Fgetenv_internal): No longer static.
9227 * ccl.h: Remove EXFUNs.
9228 * buffer.h: Remove EXFUNs.
9229 * dispextern.h: Remove EXFUNs.
9230 * intervals.h: Remove EXFUNs.
9231 * fontset.h: Remove EXFUN.

9236 * w32term.h: Remove EXFUNs.
9237 * window.h: Remove EXFUNs.
9238 * xsettings.h: Remove EXFUN.
9239 * xterm.h: Remove EXFUN.
9241 2012-07-03 Glenn Morris <rgm@gnu.org>
9243 * lisp.h (Frandom): Make it visible to C.
9244 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9245 buffer for invisible buffers. (Bug#1229)
9247 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9249 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9250 values which aren't power of 2.
9251 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9252 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9255 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9257 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9259 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9261 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9263 * alloc.c (allocate_vector_block): Remove redundant
9264 calls to mallopt if DOUG_LEA_MALLOC is defined.
9265 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9266 avoid calls to mallopt if zero_vector is returned.
9268 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9270 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9271 is enabled, avoid dereferencing NULL current_sblock if
9274 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9276 Cleanup basic buffer management.
9277 * buffer.h (struct buffer): Change layout to use generic vector
9278 marking code. Fix some comments. Change type of 'clip_changed'
9279 to bitfield. Remove unused #ifndef old.
9280 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9281 (GET_OVERLAYS_AT): Fix indentation.
9282 (for_each_per_buffer_object_at): New macro.
9283 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

9286 * alloc.c (allocate_buffer): Adjust to match new layout of
9287 struct buffer. Fix comment.
9288 (mark_overlay): New function.

9290 Lisp area of struct buffer.
9291 (mark_object): Use it. Adjust marking of misc objects
9292 and related comments.
9294 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9296 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9297 wrapper that is not needed because the wrapped code is a no-op (zero
9298 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9299 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9301 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9303 * alloc.c (mark_buffer): Simplify. Remove prototype.
9304 (mark_object): Add comment. Reorganize marking of vector-like
9305 objects. Use CHECK_LIVE for all vector-like objects except buffers
9306 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9307 Avoid redundant calls to mark_vectorlike for bool vectors.
9309 2012-06-30 Glenn Morris <rgm@gnu.org>
9311 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9313 * epaths.in (PATH_SITELOADSEARCH): New.
9314 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9315 This is rather than relying on --enable-locallisppath elements
9316 having "site-lisp" in their names. (Bug#10208#25, 11658)
9318 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9320 * w32proc.c (sys_select): Accept and ignore one more argument.
9322 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9324 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9325 (pselect) [!MS_DOS]: Redirect to sys_select.
9327 * sysdep.c: Don't include dos.h and dosfns.h.
9329 * process.c (sys_select):
9330 * msdos.c (sys_select): Accept one more argument and ignore it.
9332 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9333 adapt data types and code to that.
9336 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9337 which clashes with the gnulib function of the same name.
9339 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9341 * font.c (font_style_to_value, font_style_symbolic)
9342 (font_prop_validate_style): Add type checks for values in
9345 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9347 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9350 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9352 * xdisp.c (try_window_id): Undo last change.
9354 * w32.c (getwd): Adjust commentary about startup_dir.
9355 (init_environment): Always call sys_access, even in non-MSVC
9356 builds. Don't chdir to the directory of the Emacs executable.
9357 This undoes code from 1997 which was justified by the need to
9358 "avoid conflicts when removing and renaming directories". But its
9359 downside was that every relative file name was being interpreted
9360 relative to the directory of the Emacs executable, which can never
9361 be TRT. In particular, it broke sys_access when called with
9362 relative file names.
9363 (sys_access): Map GetLastError to errno.
9365 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9367 * window.h (struct window): Change type of 'fringes_outside_margins'

9369 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
9371 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9374 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9376 * gnutls.c (emacs_gnutls_handshake):
9377 Add QUIT to make the loop interruptible.
9379 2012-06-29 Glenn Morris <rgm@gnu.org>
9381 * charset.c (init_charset): Make lack of etc/charsets fatal.
9383 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9385 * editfns.c (region_limit): Fix type mismatch.
9387 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9389 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9390 undefined. Convert from xassert to eassert.
9391 * nsmenu.m: Convert from xassert to eassert.
9392 * nsterm.m: Likewise.
9394 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9396 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9398 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9400 Avoid integer overflow on scroll-left and scroll-right.
9401 * window.c (HSCROLL_MAX): New macro.
9402 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9403 overflow when requested scroll falls outside ptrdiff_t range.
9405 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9407 * window.h (struct window): Change type of 'hscroll',
9408 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9409 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9410 Adjust users accordingly.
9411 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9412 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9413 from EMACS_INT to ptrdiff_t.
9414 (make_window): Omit redundant initialization.
9416 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

9420 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9422 * window.h (struct window): Change type of 'use_time' and
9423 'sequence_number' from Lisp_Object to int.

9432 enabled with --enable-checking=[all,glyphs] configure option.
9433 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9434 adjust comments accordingly.

9485 avoid GCC warning about unused macro.
9487 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9489 * alloc.c (allocate_string): Omit intervals initialization.
9490 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9491 as in make_pure_string and make_pure_c_string.
9493 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9495 * alloc.c (allocate_string): Fix last change.
9497 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9500 to memset, add explicit initialization where appropriate.

9547 * alloc.c: Remove build_string.
9548 * lisp.h: Define build_string as static inline. This provides
9549 a better opportunity to optimize away calls to strlen when the
9550 function is called with compile-time constant argument.
9551 * image.c (imagemagick_error): Convert to build_string.
9552 * w32proc.c (sys_spawnve): Likewise.
9553 * xterm.c (x_term_init): Likewise.
9555 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9557 Use sprintf return value instead of invoking strlen on result.
9558 In the old days this wasn't portable, since some sprintf
9559 implementations returned char *. But they died out years ago and
9560 Emacs already assumes sprintf returns int.
9561 Similarly for float_to_string.
9562 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9563 * ccl.c (ccl_driver):
9564 * character.c (string_escape_byte8):

9567 * print.c (print_object):
9568 * xdisp.c (message_dolog):
9569 * xfns.c (syms_of_xfns):
9570 Use sprintf or float_to_string result to avoid need to call strlen.
9571 * data.c (Fnumber_to_string):
9572 Use make_unibyte_string, since the string must be ASCII.
9573 * lisp.h, print.c (float_to_string): Now returns int length.
9574 * term.c (produce_glyphless_glyph):
9575 Use sprintf result rather than recomputing it.
9577 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9578 * Makefile.in (ALL_CFLAGS):
9579 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9580 * gmalloc.c, regex.c: Include <config.h> unconditionally.
9582 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9584 * dispextern.h (xstrcasecmp): Define to library function
9585 strcasecmp if available.
9586 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
9588 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>

9601 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9603 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9604 sprintf already null-terminates its output.
9606 * xfns.c (x_window): Remove redundant cast.
9608 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9610 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9611 `const char *' to `char *' to avoid compiler warning.
9613 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9615 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9616 instead of truncating it to 63 (admittedly a generous limit).
9618 * process.c: Fix spelling and caps in comments.
9620 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9622 * emacs.c (setpgrp): Remove definition, unused.

9667 No need for separate decl merely because of _Noreturn.
9668 * sound.c (sound_warning, parse_sound):
9669 Remove unnecessary forward decls.
9671 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9673 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
9674 * lisp.h (WAIT_READING_MAX): New macro.
9675 * dispnew.c (Fsleep_for, sit_for):
9676 * keyboard.c (kbd_buffer_get_event):
9677 * process.c (Faccept_process_output):
9678 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9679 This improves on the previous patch, which introduced a bug
9680 when time_t is unsigned and as wide as intmax_t.
9681 See <http://bugs.gnu.org/9000#51>.
9683 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9685 * dispnew.c (sit_for, Fsleep_for):
9686 * keyboard.c (kbd_buffer_get_event):

9699 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9700 Privately reported by Herbert J. Skuhra.
9701 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9703 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9704 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9706 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9708 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9709 last argument of make_unibyte_string.
9711 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9712 language ID in the event parameters.
9714 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9715 event.code, not the obscure "character set ID".
9717 2012-06-23 Chong Yidong <cyd@gnu.org>
9719 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
9721 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9723 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.

9738 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9739 Privately reported by Herbert J. Skuhra.
9740 [__FreeBSD__]: Remove "*/" typo after "#include".

9746 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9748 Support higher-resolution time stamps (Bug#9000).
9749 The time stamps are only nanosecond-resolution at the C level,
9750 since that's the best that any real-world system supports now.
9751 But they are picosecond-resolution at the Lisp level, as that's
9752 easy, and leaves room for future OS improvements.
9754 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9757 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9758 Don't get current time unless it's needed.
9760 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9761 now provides it if it's absent.
9762 (start_atimer): Port to higher-res time stamps.
9763 Check for time stamp overflow. Don't get current time more
9764 often than is needed.
9766 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9767 Include systime.h, not time.h.
9768 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9770 * dired.c: Include stat-time.h.
9771 (Ffile-attributes): File times now have higher resolution.
9773 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9774 (struct image): Timestamp now has higher resolution.
9776 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9777 has at least microseconds now. All uses removed.
9778 (update_frame, update_single_window, update_window, update_frame_1)
9779 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9780 (duration_to_sec_usec): Remove; no longer needed.
9782 * editfns.c (time_overflow): Now extern.
9783 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9784 (float-time, Fformat_time_string, Fcurrent_time_string)

9787 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9788 (decode_time_components, lisp_seconds_argument): New functions.
9789 (make_time): Now static.
9790 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9791 Report an error if the time is invalid, rather than having the caller
9794 * fileio.c: Include <stat-time.h>
9795 (Fcopy_file): Copy higher-resolution time stamps.
9796 Prefer to set the time stamp via a file descriptor if that works.

9798 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9799 (Fvisited_file_modtime, Fset_visited_file_modtime):
9800 Support higher-resolution time stamps.
9802 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9804 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9806 * image.c (prepare_image_for_display, clear_image_cache)
9807 (lookup_image): Port to higer-resolution time stamps.
9809 * keyboard.c (start_polling, bind_polling_period):
9810 Check for time stamp overflow.
9811 (read_char, kbd_buffer_get_event, timer_start_idle)
9812 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9813 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9814 Port to higher-resolution time stamps. Do not assume time_t is signed.
9815 (decode_timer): New function. Timers are now vectors of length 9,
9816 not 8, to accommodate the picosecond component.
9817 (timer_check_2): Use it.
9819 * nsterm.m (select_timeout, timeval_subtract): Remove.
9820 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9821 as they're a bit more accurate and handle overflow better.
9822 (ns_select): Change prototype to be compatible with pselect.
9823 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9824 * nsterm.h (ns_select): Adjust prototype.
9826 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9827 us-resolution time stamps.
9828 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9830 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9832 * lisp.h (time_overflow): New decl.
9833 (wait_reading_process_output): First arg is now intmax_t, not int,
9834 to accommodate larger waits.
9836 * process.h (struct Lisp_Process.read_output_delay):
9837 Now counts nanoseconds, not microseconds.
9838 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9840 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9841 (wait_reading_process_output):
9842 Port to ns-resolution time stamps.
9843 (Faccept_process_output, wait_reading_process_output):
9844 Check for time stamp overflow. Do not assume time_t is signed.
9845 (select_wrapper): Remove; we now use pselect.
9846 (Fprocess_attributes): Now generates ns-resolution time stamps.
9848 * sysdep.c: Include utimens.h. Don't include utime.h
9849 or worry about struct utimbuf; gnulib does that for us now.
9850 (gettimeofday): Remove; gnulib provides a substitute.
9851 (make_timeval): New function.
9852 (set_file_times): Now sets ns-resolution time stamps.
9853 New arg FD; all uses changed.
9854 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9855 (system_process_attributes):
9856 Now returns ns-resolution time stamp. All uses changed.
9857 Check for time stamp overflow.
9859 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9860 provides a substitute now.
9862 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9863 since it guarantees struct timespec.
9864 (EMACS_TIME): Now struct timespec, so that we can support
9865 ns-resolution time stamps.
9866 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9867 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9868 (EMACS_USECS): Remove.
9869 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9870 so multiply the arg by 1000 before storing it.
9871 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9873 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9874 Port to ns-resolution time stamps.
9875 (EMACS_TIME_NEG_P): Remove; replaced by....
9876 (EMACS_TIME_SIGN): New macro.
9877 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9878 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

9880 (make_timeval, make_lisp_time, decode_time_components): New decls.
9881 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9882 that it mishandled time_t overflow. You can't compare by subtracting!
9883 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9884 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

9894 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9895 (w32_get_internal_run_time):
9896 Port to higher-resolution Emacs time stamps.
9897 (ltime): Now accepts single 64-bit integer, as that's more convenient
9900 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9902 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9903 for compatibility with pselect. Support ns-resolution time stamps.
9905 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9907 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9908 Check for time stamp overflow, and support ns-resolution time stamps.
9910 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9911 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9912 (timeval_subtract): Remove; no longer needed.
9913 (XTflash, XTring_bell, x_wait_for_event):
9914 Port to ns-resolution time stamps. Don't assume time_t is signed.
9916 2012-06-22 Chong Yidong <cyd@gnu.org>
9918 * xdisp.c (x_consider_frame_title): Revert last change.
9920 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9922 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9923 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9924 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9925 staticidx goes up to 1597 out of 1600 = 0x640.)
9927 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9929 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9930 Otherwise, the umask might be mistakenly 0 while handling input signals.
9932 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
9934 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

9950 frame's selected window and its terminal's top-frame.
9951 (unwind_format_mode_line): Restore them.
9952 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9954 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9955 since tty frames can be explicitly named.
9956 (prepare_menu_bars): Likewise.
9958 * term.c (Ftty_top_frame): New function.
9960 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9962 Port byte-code-meter to modern targets.
9963 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9964 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9965 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9966 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
9967 (METER_1, METER_2): Simplify.
9969 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
9971 * data.c (Fdefalias): Return `symbol' (bug#11686).
9973 2012-06-18 Martin Rudalics <rudalics@gmx.at>
9975 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9976 gets killed during executing of this function (Bug#11665).
9977 Try to always return Qt when the buffer has been actually killed.
9978 (Vkill_buffer_query_functions): In doc-string say that functions
9979 run by this hook should not change the current buffer.
9981 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9983 Fix recently-introduced process.c problems found by static checking.
9984 * process.c (write_queue_push, write_queue_pop, send_process):

10346 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10347 would mishandle a string argument "Xc" if X was a multibyte
10348 character of length 2: it would truncate after X's first byte
10349 rather than including all of X.
10351 2012-06-06 Chong Yidong <cyd@gnu.org>

10400 * minibuf.c (Fassoc_string): Remove duplicate declaration.
10402 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10403 Convert pctcpu and pctmem to Lisp float properly.
10404 Let the compiler fold better, as 100.0/0x8000 is exact.

10420 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10421 change its type from Lisp_Object to bitfield.
10422 Change type of 'force_start', 'optional_new_start',
10423 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

10430 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10431 Use 'float' consistently, rather than 'float' in most places
10432 and 'double' in a couple of places.
10434 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10436 * xdisp.c (handle_stop): Detect whether we have overlay strings
10437 loaded by testing it->current.overlay_string_index to be
10438 non-negative, instead of checking whether n_overlay_strings is
10439 positive. (Bug#11587)
10441 2012-05-31 Chong Yidong <cyd@gnu.org>
10443 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
10445 * doc.c (Fsubstitute_command_keys): Doc fix.
10447 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10449 * search.c (search_buffer): Remove calls to
10450 r_alloc_inhibit_buffer_relocation, as it is now called by
10451 maybe_unify_char, which was the cause of relocation of buffer text
10454 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10456 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10457 for the duration of call to load_charset, to avoid problems with
10458 callers of maybe_unify_char that access buffer text through C
10461 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10462 decrement the inhibition flag, instead of just setting or
10465 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10467 Remove obsolete '#define static' cruft.
10468 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10469 This #undef was "temporary" in 2000; it is no longer needed
10470 now that '#define static' has gone away.
10471 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10472 (gray_bitmap_bits): Remove; no longer needed.
10473 All uses replaced with definiens.
10474 * xterm.c: Include "bitmaps/gray.xbm".
10476 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10478 Clean up __executable_start, monstartup when --enable-profiling.
10479 The following changes affect the code only when profiling.
10480 * dispnew.c (__executable_start): Rename from safe_bcopy.
10481 Define only on platforms that need it.
10482 * emacs.c: Include <sys/gmon.h> when profiling.
10483 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10484 (__executable_start): Remove decl, since lisp.h does it now.
10485 (safe_bcopy): Remove decl; no longer has that name.
10486 (main): Coalesce #if into single bit of code, for simplicity.
10487 Cast pointers to uintptr_t, since standard libraries want integers
10489 * lisp.h (__executable_start): New decl.
10491 2012-05-31 Glenn Morris <rgm@gnu.org>
10493 * image.c (Fimagemagick_types): Doc fix.
10495 2012-05-30 Jim Meyering <meyering@redhat.com>
10497 * callproc.c (Fcall_process_region): Include directory component
10498 in mkstemp error message (Bug#11586).
10500 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10502 * alloc.c, lisp.h (make_pure_vector): Now static.
10504 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
10506 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
10507 Move to byte-run.el.

10509 * data.c (Fdefalias): Purify definition, except for keymaps.
10510 (Qdefun): Move from eval.c.
10511 * lisp.h (Qdefun): Remove.
10512 * lread.c (read1): Tiny simplification.
10514 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10516 Do not create empty overlays with the evaporate property (Bug#9642).
10517 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10518 Bug#9642, but explicitly check that the buffer the overlay would
10519 be moved to is live and rearrange lines to make sure that errors
10520 will not put the overlay in an inconsistent state.
10521 (Fdelete_overlay): Cosmetics.
10523 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10525 * w32term.c (my_bring_window_to_top): New function.
10526 (x_raise_frame): Use handle returned by DeferWindowPos, which
10527 could be different from the original one.
10528 Call my_bring_window_to_top instead of my_set_foreground_window.
10531 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
10532 by calling BringWindowToTop.

10537 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10539 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10540 This avoids undefined behavior that might cause the eassert
10541 to not catch an out-of-range value.
10543 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10545 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10546 Update dependencies.
10548 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10550 * bidi.c (bidi_mirror_char): Fix last change.
10552 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
10554 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
10555 when referring to sectname field in printf format.
10557 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10559 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10560 Only r_alloc_inhibit_buffer_relocation needed to be added;
10561 the others were already declared.
10563 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10564 before checking whether it's out of range. Put the check inside
10566 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10568 2012-05-27 Ken Brown <kbrown@cornell.edu>
10570 * callproc.c (Fcall_process): Restore a line that was accidentally
10571 commented out in the 2011-02-13 change (bug#11547).
10573 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10575 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10576 defined on ralloc.c.
10578 * buffer.c [REL_ALLOC]: Remove prototypes of
10579 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10580 they are now on lisp.h.
10582 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10584 * search.c (search_buffer): Use it to inhibit relocation of buffer
10585 text while re_search_2 is doing its job, because re_search_2 is
10586 passed C pointers to buffer text. (Bug#11519)
10588 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10589 Update value to 24.
10591 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10592 state after an additional call to move_it_in_display_line_to, keep
10593 the values of it->max_ascent and it->max_descent found for the
10595 (pos_visible_p): Revert the comparison against bottom_y to what it
10596 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10599 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10601 Fix coding-related core dumps with gcc -ftrapv.
10602 The code was computing A - B, where A and B are pointers, and B is
10603 random garbage. This can lead to core dumps on platforms that
10604 have special pointer registers, and it also leads to core dumps on
10605 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10606 A - B only when B is initialized properly.
10607 * coding.c (coding_set_source, coding_set_destination): Return void.
10608 (coding_change_source, coding_change_destinations): New functions,
10609 with the old behaviors of coding_set_source and coding_set_destination.
10610 All callers that need an offset changed to use these new functions.
10612 2012-05-26 Glenn Morris <rgm@gnu.org>
10614 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
10616 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10618 Extend mouse support on W32 text-mode console.
10619 * xdisp.c (draw_row_with_mouse_face):
10620 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10622 * w32console.c: Include window.h.
10623 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10625 (initialize_w32_display): Initialize mouse-highlight data.
10627 * w32inevt.c: Include termchar.h and window.h.
10628 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10629 moves, call note_mouse_highlight. If help_echo changed, call
10630 gen_help_event to produce help-echo message in the echo area.
10631 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10634 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10636 * lread.c (read1): Simplify slightly to avoid an overflow warning
10637 with GCC 4.7.0 on x86-64.
10639 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10641 * bidi.c (bidi_mirror_char): Revert last change: an int is
10642 definitely wide enough here.
10644 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10646 Fix integer width and related bugs (Bug#9874).
10647 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
10648 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
10649 (string_bytes, check_sblock, allocate_string_data):
10650 (compact_small_strings, Fmake_bool_vector, make_string)
10651 (make_unibyte_string, make_multibyte_string)
10652 (make_string_from_bytes, make_specified_string)
10653 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10654 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10656 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10657 (allocate_pseudovector):
10658 Use int, not EMACS_INT, where int is wide enough.
10659 (inhibit_garbage_collection, Fgarbage_collect):
10660 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10661 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10662 int might not be wide enough.
10663 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10664 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10665 (bidi_at_paragraph_end, bidi_find_paragraph_start)
10666 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
10667 (bidi_level_of_next_char, bidi_move_to_visually_next):
10668 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10669 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
10670 (Fkill_buffer, Fset_buffer_major_mode)
10671 (advance_to_char_boundary, Fbuffer_swap_text)
10672 (Fset_buffer_multibyte, overlays_at, overlays_in)
10673 (overlay_touches_p, struct sortvec, record_overlay_string)
10674 (overlay_strings, recenter_overlay_lists)
10675 (adjust_overlays_for_insert, adjust_overlays_for_delete)
10676 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
10677 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
10678 (Foverlay_recenter, last_overlay_modification_hooks_used)
10679 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10680 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10681 (validate_region): Omit unnecessary test for b <= e,
10682 since that's guaranteed by the previous test.
10683 (adjust_overlays_for_delete): Avoid pos + length overflow.
10684 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10685 (report_overlay_modification):
10686 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10687 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10688 Omit pointer cast, which isn't needed anyway, and doesn't work
10689 after the EMACS_INT -> ptrdiff_t change.
10690 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10691 * buffer.h: Adjust decls to match defn changes elsewhere.
10692 (struct buffer_text, struct buffer):
10693 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10694 Use EMACS_INT, not int, where int might not be wide enough.
10695 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10696 not int, to avoid needless 32-bit limit on 64-bit hosts.
10697 (exec_byte_code): Use tighter memory-full test, one that checks
10698 for alloca overflow. Don't compute the address of the object just
10699 before an array, as that's not portable. Use EMACS_INT, not
10700 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10701 * callint.c (Fcall_interactively):
10702 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10703 * callproc.c (call_process_kill, Fcall_process):
10704 Don't assume pid_t fits into an Emacs fixnum.
10705 (call_process_cleanup, Fcall_process, child_setup):
10706 Don't assume pid_t fits into int.
10707 (call_process_cleanup, Fcall_process, delete_temp_file)
10708 (Fcall_process_region):
10709 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10710 (Fcall_process): Simplify handling of volatile integers.
10711 Use int, not EMACS_INT, where int will do.
10712 * casefiddle.c (casify_object, casify_region, operate_on_word)
10713 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10714 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10715 (casify_object): Avoid integer overflow when overallocating buffer.
10716 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10717 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10718 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10719 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10720 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10721 integers are now checked earlier. All uses replaced with XINT.
10723 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10724 For CCL_MapSingle, check that content and value are in int range.
10725 (ccl_driver, Fregister_code_conversion_map):
10726 Check that Vcode_version_map_vector is a vector.
10727 (resolve_symbol_ccl_program): Check that vector header is in range.
10728 Always copy the vector, so that we can check its contents reliably
10729 now rather than having to recheck each instruction as it's being
10730 executed. Check that vector words fit in 'int'.
10731 (ccl_get_compiled_code, Fregister_ccl_program)
10732 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10733 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10734 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10735 contents are in range.
10736 (Fccl_execute_on_string): Check that status is in range.
10737 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10738 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10739 Accept and return EMACS_INT, not int, because callers can pass values
10740 out of 'int' range.
10741 (c_string_width, strwidth, lisp_string_width, chars_in_text)
10742 (multibyte_chars_in_text, parse_str_as_multibyte)

10744 (str_as_unibyte, str_to_unibyte, string_count_byte8)
10745 (string_escape_byte8, Fget_byte):
10746 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10747 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10748 avoid mishandling large integers.
10749 * character.h: Adjust decls to match defn changes elsewhere.
10750 * charset.c (load_charset_map_from_file, find_charsets_in_text)
10751 (Ffind_charset_region):
10752 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10753 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
10754 (load_charset_map_from_vector, Fdefine_charset_internal):
10755 Don't assume fixnum fits in int.
10756 (load_charset_map_from_vector, Fmap_charset_chars):
10757 Remove now-unnecessary CHECK_NATNUMs.
10758 (Fdefine_charset_internal): Check ranges here, more carefully.
10759 Don't rely on undefined behavior with signed left shift overflow.
10760 Don't assume unsigned int fits into fixnum, or that fixnum fits
10761 into unsigned int. Don't require max_code to be a valid fixnum;
10762 that's not true for gb10830 4-byte on a 32-bit host. Allow
10763 invalid_code to be a cons, for the same reason. Require code_offset
10764 to be a character. Avoid int overflow if max_char is close
10766 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10767 this is intended anyway and avoids some undefined behavior.
10768 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10769 INDEX_TO_CODE_POINT, as that's what it expects.
10770 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10771 * charset.h (DECODE_CHAR): Return int, not unsigned;
10772 this is what was intended anyway, and it avoids undefined behavior.
10773 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10774 integer-overflow issues.
10775 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10776 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10777 where the argument is EMACS_INT, and this behavior is not intended.
10778 * chartab.c (Fmake_char_table, Fset_char_table_range)
10779 (uniprop_get_decoder, uniprop_get_encoder):
10780 Don't assume fixnum fits in int.
10781 * cmds.c (move_point): New function, that does the gist of
10782 Fforward_char and Fbackward_char, but does so while checking
10783 for integer overflow more accurately.
10784 (Fforward_char, Fbackward_char): Use it.
10785 (Fforward_line, Fend_of_line, internal_self_insert)
10786 (internal_self_insert):
10787 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10788 Fix a FIXME, by checking for integer overflow when calculating
10789 target_clm and actual_clm.

10821 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10822 (consume_chars): Rewrite to not calculate an address outside buffer.
10823 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
10824 Don't access memory outside of the args array.
10825 (Fdefine_coding_system_internal): Check for charset-id overflow.
10826 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
10827 result of ENCODE_CHAR.
10828 * coding.h: Adjust decls to match defn changes elsewhere.
10829 (struct coding_system):

11512 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
11513 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
11514 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
11515 * xterm.c (input_signal_count): Assume volatile works.
11517 2012-05-21 Ken Brown <kbrown@cornell.edu>
11519 * xgselect.c (xg_select): Fix first argument in call to 'select'
11522 2012-05-20 Ken Brown <kbrown@cornell.edu>
11524 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
11525 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11527 2012-05-19 Ken Brown <kbrown@cornell.edu>
11529 * xfns.c (x_in_use): Remove `static' qualifier.
11530 * xterm.h (x_in_use): Declare.
11531 * xgselect.c: Include xterm.h.
11532 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11533 and `display_arg' (bug#9754).
11535 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11537 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11539 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11540 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11542 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11544 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11546 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11547 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11549 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11550 reference to image_cache->refcount.
11551 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11553 2012-05-17 Juri Linkov <juri@jurta.org>
11555 * search.c (Fword_search_regexp, Fword_search_backward)
11556 (Fword_search_forward, Fword_search_backward_lax)
11557 (Fword_search_forward_lax): Move functions to isearch.el
11558 (bug#10145, bug#11381).
11560 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11562 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11564 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11566 * lread.c (init_obarray): Declare Qt and Qnil as special.
11568 2012-05-14 Glenn Morris <rgm@gnu.org>
11570 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11571 Put "libexec" before "bin", for the sake of init_callproc_1.
11573 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11575 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11577 * unexaix.c: Port to more-recent AIX compilers.
11578 (report_error, report_error_1, make_hdr, copy_sym)
11579 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11580 Make arguments const char *, not char *, to avoid violations of C
11581 standard and to fix some AIX warnings reported by Gilles Pion.
11583 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11585 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11586 already have overlays loaded.
11587 (handle_single_display_spec): Before returning without displaying
11588 fringe bitmap, synchronize the bidi iterator with the main display
11589 iterator, by calling iterate_out_of_display_property.
11590 (iterate_out_of_display_property): Detect buffer iteration by
11591 testing that it->string is a Lisp string.
11592 (get_next_display_element): When the current object is exhausted,
11593 and there's something on it->stack, call set_iterator_to_next to
11594 proceed with what's on the stack, instead of returning zero.
11595 (set_iterator_to_next): If called at the end of a Lisp string,
11596 proceed to consider_string_end without incrementing string
11597 position. Don't increment display vector index past the end of
11598 the display vector. (Bug#11417)
11599 (pos_visible_p): Don't report a position visible when move_it_to
11600 stopped at the last line of window, which happens to be scanned
11601 backwards by the bidi iteration. (Bug#11464)
11603 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11605 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11606 and right-margin display specs even if the spec is invalid or we
11607 are on a TTY, and thus unable to display on the fringes.
11608 That's because the text with the property will not be displayed anyway,
11609 so we need to signal to the caller that this is a "replacing"
11610 display spec. This fixes display when the spec is invalid or we
11613 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11615 * unexaix.c (make_hdr): Fix typo in prototype.
11616 This bug broke the build on AIX. Problem reported by Gilles Pion.
11618 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11620 * keyboard.c (kbd_buffer_get_event): Read special events also in
11621 batch mode. (Bug#11415)
11623 2012-05-12 Glenn Morris <rgm@gnu.org>
11625 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11627 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11629 * lisp.mk (lisp): Add newcomment.elc.
11631 2012-05-12 Glenn Morris <rgm@gnu.org>
11633 * Makefile.in (MKDIR_P): New, set by configure.
11634 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11636 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11638 Remove unused function hourglass_started.
11639 * dispextern.h (hourglass_started):
11640 * w32fns.c (hourglass_started):
11641 * xdisp.c (hourglass_started): Remove.
11643 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11645 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11646 Update dependencies.
11648 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11650 * xgselect.c (xg_select): Put maxfds+1 into a var.
11651 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11653 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11655 2012-05-10 Dave Abrahams <dave@boostpro.com>
11657 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11658 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11660 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11662 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11663 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11664 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11665 Initialize xd_registered_buses.
11667 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11669 Untag more efficiently if USE_LSB_TAG.
11670 This is based on a proposal by YAMAMOTO Mitsuharu in
11671 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11672 For an admittedly artificial (nth 8000 longlist) benchmark on
11673 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11674 Emacs's overall text size by 1%.
11675 * lisp.h (XUNTAG): New macro.
11676 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11677 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11678 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11679 * eval.c (Fautoload):
11680 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11681 * frame.h (XFRAME): Use XUNTAG.
11683 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11684 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11685 Remove unportable assumptions about print widths of types like
11687 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11688 intptr_t when converting between pointer and integer, to avoid GCC
11689 warnings about wrong width.
11691 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11693 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11694 stack for each reader_thread, instead of defaulting to 8MB
11695 determined by the linker. This avoids failures in creating
11696 subprocesses on Windows 7, see the discussion in this thread:
11697 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11699 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11701 Fix up display of the *Minibuf-0* buffer in the mini window.
11702 * keyboard.c (read_char): Don't clear the echo area if there's no
11704 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11705 contents of *Minibuf-0*) if there's no message displayed in its stead.
11707 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11709 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11712 2012-05-06 Chong Yidong <cyd@gnu.org>
11714 * lisp.mk (lisp): Update.
11716 2012-05-05 Jim Meyering <meyering@redhat.com>
11718 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11720 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11722 * data.c (PUT_ERROR): New macro.
11723 (syms_of_data): Use it. Add new error type `user-error'.
11724 * undo.c (user_error): New function.
11725 (Fprimitive_undo): Use it.
11726 * print.c (print_error_message): Adjust print style for `user-error'.
11727 * keyboard.c (user_error): New function.
11728 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11730 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11732 Do not limit current-time-string to years 1000..9999.
11733 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11734 (Fcurrent_time_string): Support any year that is supported by the
11735 underlying localtime representation. Don't use asctime, as it
11736 has undefined behavior for years outside the range -999..9999.
11738 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11740 Fix race conditions involving setenv, gmtime, localtime, asctime.
11741 Without this fix, interrupts could mess up code that uses these
11742 nonreentrant functions, since setting TZ invalidates existing
11743 tm_zone or tzname values, and since most of these functions return
11744 pointers to static storage.
11745 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11746 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11747 Grow the critical sections to include not just invoking
11748 localtime/gmtime, but also accessing these functions' results
11749 including their tm_zone values if any, and any related TZ setting.
11750 (format_time_string): Last arg is now struct tm *, not struct tm **,
11751 so that the struct tm is saved in the critical section.
11752 All callers changed. Simplify allocation of initial buffer, partly
11753 motivated by the fact that memory allocation needs to be outside
11754 the critical section.
11756 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11758 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11759 with RESET_INTERVAL.
11761 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11762 Remove duplicated buffer name initialization.
11764 2012-05-02 Jim Meyering <jim@meyering.net>
11766 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11768 * xfns.c (x_window): Use xstrdup (Bug#11375).
11770 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11772 * xdisp.c (pos_visible_p): If already at a newline from the
11773 display string before the 'while' loop, don't walk back the glyphs
11774 from it3.glyph_row. Solves assertion violation when the display
11775 string begins with a newline (egg.el). (Bug#11367)
11777 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11779 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11782 2012-05-01 Glenn Morris <rgm@gnu.org>
11784 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11785 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11786 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11787 All were removed before 23.1.
11789 * dispnew.c: Remove HAVE_LIBNCURSES test;
11790 it is always true on relevant platforms.
11792 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11793 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11795 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11797 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11799 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11800 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11803 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11805 Do not avoid creating empty evaporating overlays (Bug#9642).
11806 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11807 That is, do not delete an evaporating overlay if it becomes
11808 empty after its bounds are adjusted to fit within its buffer.
11809 This fix caused other problems, and I'm reverting it until we get
11810 to the bottom of them.
11812 2012-04-27 Chong Yidong <cyd@gnu.org>
11814 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11816 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11818 * xdisp.c (pos_visible_p): If the window start position is beyond
11819 ZV, start the display from buffer beginning. Prevents assertion
11820 violation in init_iterator when the minibuffer window is scrolled
11821 via the scroll bar.
11823 * window.c (window_scroll_pixel_based): Likewise.
11825 2012-04-27 Chong Yidong <cyd@gnu.org>
11827 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11829 2012-04-27 Glenn Morris <rgm@gnu.org>
11831 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11832 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11834 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11836 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11837 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11839 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11841 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11842 display element, check also the underlying string or buffer
11843 character. (Bug#11341)
11845 * w32menu.c: Include w32heap.h.
11846 (add_menu_item): If the call to AppendMenuW (via
11847 unicode_append_menu) fails, disable Unicode menus only if we are
11848 running on Windows 9X/Me.
11850 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11852 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11853 (xgetint): Add missing shift for LSB tags.
11855 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11857 * keyboard.c (read_char): Don't wipe echo area for select window
11858 events: These might get delayed via `mouse-autoselect-window'
11861 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11863 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11864 manipulation of :loaded-from data.
11866 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11868 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11869 now a cons (bug#11311).
11871 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11873 Do not create empty overlays with the evaporate property (Bug#9642).
11874 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11875 if it becomes empty after its bounds are adjusted to fit within
11876 its buffer. Without this fix, in a nonempty buffer (let ((o
11877 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11878 yields an empty overlay that has the evaporate property, which is
11879 not supposed to happen.
11881 Fix minor GTK3 problems found by static checking.
11882 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11883 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11884 (struct _EmacsFixedClass, emacs_fixed_get_type):
11885 Move decls here from emacsgtkfixed.h, since they needn't be public.
11886 (emacs_fixed_get_type): Now static.
11887 (emacs_fixed_class_init): Omit unused local.
11888 (emacs_fixed_child_type): Remove; unused.
11889 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11890 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11891 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11892 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11893 (EMACS_FIXED_GET_CLASS): Remove; unused.
11894 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11896 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11897 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11899 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11901 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11902 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11903 (__malloc_size_t, __malloc_ptrdiff_t):
11904 Remove. All uses removed, replaced by the definiens if needed,
11905 since we can assume C89 or better now.
11906 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
11907 (protect_malloc_state, align, get_contiguous_space)
11908 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

11911 (_malloc_internal_nolock, _malloc_internal, malloc, _malloc)
11912 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
11913 (special_realloc, _realloc_internal_nolock, _realloc_internal)
11914 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11915 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11916 Define using prototypes, not old style.
11917 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11918 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11919 (align): Don't assume that signed integer overflow wraps around.
11920 Omit unused local var.
11921 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
11922 (_free_internal_nolock, memalign, mallochook, reallochook):
11923 Omit no-longer-needed casts.
11924 (valloc): Use getpagesize, not __getpagesize.
11925 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11926 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11928 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11930 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11932 Move functions from C to Lisp. Make non-blocking method calls
11933 the default. Implement further D-Bus standard interfaces.
11935 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
11936 (QCdbus_request_name_allow_replacement)
11937 (QCdbus_request_name_replace_existing)

11943 (QCdbus_registered_serial, QCdbus_registered_method)
11944 (QCdbus_registered_signal): New Lisp objects.
11945 (XD_DEBUG_MESSAGE): Use sizeof.

11948 (XD_DBUS_VALIDATE_BUS_NAME, XD_DBUS_VALIDATE_PATH)
11949 (XD_DBUS_VALIDATE_INTERFACE, XD_DBUS_VALIDATE_MEMBER): New macros.

11994 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11996 * sysdep.c [__FreeBSD__]: Minor cleanups.
11997 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11998 Use Emacs indenting style more consistently. Avoid some casts.

12003 * sysdep.c (list_system_processes, system_process_attributes):
12004 Add implementation for FreeBSD (Bug#5243).

12010 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
12012 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
12013 It is never used otherwise.
12015 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
12017 * print.c (print_preprocess): Only check print_depth if print-circle
12019 (print_object): Check for cycles even when print-circle is nil and

12024 * process.c (wait_reading_process_output): If EIO occurs on a pty,
12025 set the status to "failed" and ensure that sentinel is run.
12027 2012-04-20 Glenn Morris <rgm@gnu.org>
12029 * process.c (Fset_process_inherit_coding_system_flag)
12030 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

12058 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
12059 -Wunused-result, -Wunused-variable. This should go away once
12060 the Emacs and Gnulib regex code is merged.
12061 (xmalloc, xrealloc): Now static.
12063 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

12080 New extern decls, to avoid calling undeclared functions.
12081 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
12082 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12083 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12084 (NEED_MEM_INSERT): New macro.
12085 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12086 Remove one incorrect comment and fix another.

12101 Remove decls. This fixes an "It stinks!".
12103 * alloc.c (which_symbols): Fix alignment issue / type clash.
12105 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
12107 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

12122 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12123 * s/netbsd.h, s/sol2-6.h:
12124 Remove definition of GC_MARK_STACK, since the default now works.
12125 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

12127 no longer the default.
12128 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12130 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
12132 * lread.c (lisp_file_lexically_bound_p):

12149 2012-04-13 Reuben Thomas <rrt@sc3d.org>
12151 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
12153 2012-04-11 Daniel Colascione <dancol@dancol.org>
12155 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12156 against is gone. It's better to use vfork now so that when Cygwin
12157 gains a new, working vfork, we use it automatically (bug#10398).
12159 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
12161 * window.c (save_window_save): Obey window-point-insertion-type.

12179 * w32.c (w32_delayed_load): Record the full path of the library
12180 being loaded (bug#10424).
12182 2012-04-09 Glenn Morris <rgm@gnu.org>
12184 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12185 not just in the obarray, before snarfing them. (Bug#11036)

12202 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12203 attempts per process (connection).
12205 2012-04-09 Chong Yidong <cyd@gnu.org>
12207 * eval.c (Fuser_variable_p, user_variable_p_eh)

12209 (Fdefvar): Caller changed.
12211 * callint.c (Finteractive, Fcall_interactively):
12212 * minibuf.c (Fread_variable): Callers changed.
12214 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12216 * xdisp.c (set_cursor_from_row): If the display string appears in
12217 the buffer at position that is closer to point than the position
12218 after the display string, display the cursor on the first glyph of
12219 the display string. Fixes cursor display when a 'display' text
12220 property immediately follows invisible text. (Bug#11094)
12222 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12224 composite.c: use 'double' consistently
12225 * composite.c (get_composition_id): Use 'double' consistently
12226 instead of converting 'float' to 'double' and vice versa; this is
12227 easier to understand and avoids a GCC warning.
12229 2012-04-09 Glenn Morris <rgm@gnu.org>
12231 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12232 preparation for dumping it with emacs. (Bug#4789)

12254 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12255 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12256 objects, as mark_maybe_pointer will catch them otherwise.

12271 ($(BLD)/xml.$(O)): New dependency list.
12273 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12274 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12275 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12276 [!WINDOWSNT]: New macros.
12277 (init_libxml2_functions, libxml2_loaded_p): New functions.
12278 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12279 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12280 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12281 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12283 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12284 Call init_libxml2_functions before calling libxml2 functions.
12285 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12287 * emacs.c: Don't include libxml/parser.h.
12288 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12289 xmlCleanupParser directly.
12291 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12293 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12295 * indent.c (Fvertical_motion): If there is a display string at
12296 point, use it.vpos to compute how many lines to backtrack after
12297 move_it_to point. (Bug#11133)
12299 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12301 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12302 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12303 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12304 macros related to unification of CJK characters. For the details,
12305 see the discussion following the message here:
12306 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12308 2012-04-04 Chong Yidong <cyd@gnu.org>
12310 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12312 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12314 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

12319 * w32menu.c (is_simple_dialog): Properly check lisp types.
12322 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12324 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12325 position we get to after a call to move_it_to fails the
12326 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12327 only if we wind up in a string from display property. (Bug#11063)
12329 * window.c (Fdelete_other_windows_internal): Invalidate the row
12330 and column information about mouse highlight, so that redisplay
12331 restores it after reallocating the glyph matrices. (Bug#7464)
12333 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12334 string comes from a `display' text property, use the buffer
12335 position of that property as if we actually saw that position in
12337 (move_it_by_lines): Remove the assertion that
12338 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12339 violated when there's a before-string at the beginning of a line.
12342 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12344 * xdisp.c (append_space_for_newline): If the default face was
12345 remapped, use the remapped face for the appended newline.
12346 (extend_face_to_end_of_line): Use the remapped default face for
12347 extending the face to the end of the line.
12348 (display_line): Call extend_face_to_end_of_line when the default
12349 face was remapped. (Bug#11068)
12351 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12353 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12355 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

12371 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12372 (command_loop_1): Use it; inhibit selection update for

12379 2012-03-25 Kenichi Handa <handa@m17n.org>
12381 * dispextern.h (struct glyph): Change the bit length of
12382 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12384 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12386 * s/ms-w32.h (tzname): Include time.h before redirecting to

12395 !SYNC_INPUT. (Bug#11080)
12397 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12399 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12400 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12401 when fetching a multibyte character consumes more bytes than
12402 CHAR_BYTES returns, due to unification of CJK characters in
12403 string_char. (Bug#11073)
12405 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12407 * process.c (wait_reading_process_output): Handle pty disconnect
12408 by refraining from sending oneself a SIGCHLD (bug#10933).

12437 it fit in a valid range (Bug#11003).
12439 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12441 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12442 that is not from display property, accept the row as a "cursor
12443 row" if one of the string's character has a non-nil `cursor'
12444 property. Fixes cursor positioning when there are newlines in
12445 overlay strings, e.g. in icomplete.el. (Bug#11035)
12447 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12449 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

12481 2012-03-03 Glenn Morris <rgm@gnu.org>
12483 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12485 2012-03-02 Eli Zaretskii <eliz@gnu.org>

12498 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12500 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12501 push_it before setting up the iterator for the first overlay
12502 string, even if we have an empty string loaded.
12503 (next_overlay_string): If there's an empty string on the iterator
12504 stack, pop the stack. (Bug#10903)
12506 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12508 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12509 Suggested by Stefan Monnier in
12510 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12511 * alloc.c (widen_to_Lisp_Object): New static function.
12512 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12513 and widening them to Lisp_Objects. This would work even if
12514 USE_LSB_TAG is defined and wide integers are used, which might
12515 happen in a future version of Emacs.
12517 2012-02-25 Chong Yidong <cyd@gnu.org>
12519 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

12524 before saving to clipboard manager.
12526 2012-02-24 Chong Yidong <cyd@gnu.org>
12528 * keyboard.c (process_special_events): Handle all X selection
12529 requests in kbd_buffer, not just the next one (Bug#8869).
12531 2012-02-23 Chong Yidong <cyd@gnu.org>
12533 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12534 call when setting menu-bar-lines and tool-bar-lines parameters.
12535 (unwind_create_frame_1): New helper function.

12555 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
12556 when computing $valmask.
12558 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12559 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12560 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12561 It's useless in that case, and it can cause problems on hosts
12562 that allocate halves of EMACS_INT values separately.
12563 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12564 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12565 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12566 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12567 it avoids undefined behavior on hosts where shifting right by more
12568 than the word width has undefined behavior.
12570 2012-02-19 Chong Yidong <cyd@gnu.org>
12572 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12573 (Funhandled_file_name_directory, Ffile_name_as_directory)
12574 (Fdirectory_file_name, Fexpand_file_name)
12575 (Fsubstitute_in_file_name): Protect against invalid file handler
12576 return values (Bug#10845).

12590 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12592 2012-02-15 Chong Yidong <cyd@gnu.org>
12594 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12595 marked as special. Also, starting docstrings with * is obsolete.

12610 2012-02-12 Chong Yidong <cyd@gnu.org>
12612 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12613 as that creates a dangerous corner case.
12615 * window.c (Fdelete_window_internal): Invalidate the mouse
12616 highlight (Bug#9904).
12618 2012-02-12 Glenn Morris <rgm@gnu.org>

12623 * nsselect.m (Fx_own_selection_internal)
12624 (Fx_disown_selection_internal, Fx_selection_exists_p)
12625 (Fx_selection_owner_p, Fx_get_selection_internal):
12626 Sync docs and argument specs with the xselect.c versions.
12628 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

12648 2012-02-07 Chong Yidong <cyd@gnu.org>
12650 * buffer.c (Fbuffer_local_variables)
12651 (buffer_lisp_local_variables): Handle unbound vars correctly;
12652 don't let Qunbound leak into Lisp.
12654 2012-02-07 Glenn Morris <rgm@gnu.org>
12656 * image.c (Fimagemagick_types): Doc fix.
12658 * image.c (imagemagick-render-type): Change it from a lisp object
12659 to an integer. Move the doc here from the lisp manual.

12676 2012-02-04 Eli Zaretskii <eliz@gnu.org>
12678 * w32.c (get_emacs_configuration_options):
12679 Include --enable-checking, if specified, in the return value.

12689 before BEGV. (Bug#10696)
12691 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
12693 Handle overflow when computing char display width (Bug#9496).
12694 * character.c (char_width): Return EMACS_INT, not int.
12695 (char_width, c_string_width): Check for overflow when
12696 computing the width; this is possible now that individual
12697 characters can have unbounded width. Problem introduced
12698 by merge from Emacs 23 on 2012-01-19.

12718 0, do not call append_composite_glyph.
12720 2012-02-02 Kenichi Handa <handa@m17n.org>
12722 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
12724 (x_produce_glyphs): If the component of a composition is a null
12725 string, set it->pixel_width to 1 to avoid zero-width glyph.

12729 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
12730 first 2 arguments are identical. This makes inserting large
12731 output from a subprocess an order of magnitude faster on
12732 MS-Windows, where all sbrk'ed memory is always contiguous.
12734 2012-01-31 Glenn Morris <rgm@gnu.org>

12817 2012-01-11 Glenn Morris <rgm@gnu.org>
12819 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
12820 from load-path also when installation-directory is nil. (Bug#10208)

12827 Update template values to be closer to their typical values these days.
12829 2012-01-09 Eli Zaretskii <eliz@gnu.org>
12831 * xdisp.c (rows_from_pos_range): Accept additional argument
12832 DISP_STRING, and accept any glyph in a row whose object is that
12833 string as eligible for mouse highlight. Fixes mouse highlight of
12834 display strings from overlays. (Bug#10464)
12836 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
12838 emacs: fix an auto-save permissions race condition (Bug#10400)
12839 * fileio.c (auto_saving_dir_umask): New static var.
12840 (Fmake_directory_internal): Use it.
12841 (do_auto_save_make_dir): Set it, instead of invoking chmod after

12845 (Fdo_auto_save): Catch all errors, not just file errors, so
12846 that the var is always cleared.

12850 * search.c (scan_buffer): Pass character positions to

13347 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
13348 Otherwise, valgrind does not work on some platforms.
13349 Problem reported by Andreas Schwab in
13350 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
13351 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13352 is set, removing the need for VIRT_ADDRESS_VARIES.
13353 (PURE_P): Use a more-efficient implementation that needs just one
13354 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
13355 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
13356 to 4 (xorl, subq, cmpq, setbe).
13357 * alloc.c (pure): Always extern now, since that's the
13358 VIRT_ADDR_VARIES behavior.

13818 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
13820 * lisp.h (struct Lisp_Symbol): Update comments.
13822 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
13824 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
13826 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13828 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
13829 <oslsachem@gmail.com> for helping to debug this.
13831 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
13832 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
13833 (g_b_init_get_glyph_outline_w): New static variables.
13834 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
13835 (GetGlyphOutlineW_Proc): New typedefs.
13836 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
13837 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
13839 (w32font_open_internal, compute_metrics):
13840 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13841 instead of calling the "wide" APIs directly.
13843 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13845 * w32.h (syms_of_w32font): Add prototype.
13847 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13849 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
13850 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
13851 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
13852 (Fmove_to_window_line): Doc fix.
13854 2011-10-27 Chong Yidong <cyd@gnu.org>
13856 * process.c (make_process): Set gnutls_state to NULL.
13858 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13859 non-NULL, regardless of GNUTLS_INITSTAGE.
13860 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13861 an error. Set process slots as soon as we allocate them.
13863 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13865 2011-10-27 Chong Yidong <cyd@gnu.org>
13867 * gnutls.c (emacs_gnutls_deinit): New function.
13868 Deallocate credentials structures as well as calling gnutls_deinit.
13869 (Fgnutls_deinit, Fgnutls_boot): Use it.
13871 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13872 (deactivate_process): Call emacs_gnutls_deinit.
13874 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13876 * image.c (x_create_x_image_and_pixmap):
13877 * w32.c (sys_rename, w32_delayed_load):
13878 * w32font.c (fill_in_logfont):
13879 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13881 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13883 * w32fns.c (w32_default_color_map): New function,
13884 extracted from Fw32_default_color_map.
13885 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13887 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13889 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13891 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13893 * keyboard.c (test_undefined): New function (bug#9751).
13894 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13896 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13898 * sysdep.c (init_sys_modes): Fix the check for the controlling
13899 terminal (Bug#6649).
13901 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13903 * dispextern.h (struct bidi_it): New member next_en_type.
13905 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13906 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13907 current character, check also for next_en_type being WEAK_EN.
13908 (bidi_resolve_weak): Don't enter the expensive loop if the current
13909 position is before next_en_pos. Record the bidi type of the first
13910 non-ET, non-BN character we find, in addition to its position.
13911 (bidi_level_of_next_char): Invalidate next_en_type when
13912 next_en_pos is over-stepped.
13914 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13916 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13917 * editfns.c: Rewrite current-time-zone so that it invokes
13918 the equivalent of (format-time-string "%Z") to get the time zone name.
13919 This fixes a bug when the time zone name contains characters that
13920 need converting from the system time locale to Emacs internal format.
13921 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13922 that patch fixed format-time-string to do the conversion, but
13923 I forgot to fix current-time-zone.
13924 (format_time_string): New function, containing most of
13925 what Fformat_time_string used to contain.
13926 (Fformat_time_string): Rewrite in terms of format_time_string.
13927 This doesn't change this function's behavior.
13928 (current-time-zone): Rewrite to use format_time_string.
13929 This fixes the bug reported by Michael Schierl in
13930 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13931 Jason Rumney's 2007-06-07 change worked around this bug, but
13933 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13935 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13937 * xdisp.c (start_display): If the character at POS is displayed
13938 via a display vector, reset IT->current.dpvec_index to zero.
13939 (try_window_reusing_current_matrix): If a line ends in a display
13940 vector or the next line starts in a display vector, continue
13941 redrawing the window even though the character position of
13942 start_row was reached.
13945 2011-10-18 Chong Yidong <cyd@gnu.org>
13947 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13948 with nobreak-char-display too.
13950 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13952 Fix part 3 of bug#9771.
13953 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13954 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13955 non-neutral characters if the current character is a paragraph
13956 separator (a.k.a. Newline). This avoids running the same
13957 expensive loop twice, once when we consume the preceding newline
13958 and the other time when the line actually needs to be displayed.
13959 Avoid the loop when we see neutrals on the base embedding level
13960 following a character whose directionality is the same as the
13961 paragraph's. This avoids running the expensive loop when a line
13962 ends in a long sequence of neutrals, like control characters.
13963 Add assertion against STRONG_AL type. Slightly rearrange code
13964 that determines the type of a neutral given the first non-neutral
13966 (bidi_level_of_next_char): Set next_en_pos to zero when
13967 invalidating its info.
13969 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13971 * xdisp.c (push_display_prop): Determine whether to record string
13972 or buffer position by IT->string, not by IT->method. Allow
13973 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13974 (move_it_vertically_backward): Don't look for character position
13975 immediately after the newline when in a continuation line.
13978 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13980 * window.c (coordinates_in_window): Rewrite and delabelize
13981 vertical border check. (Bug#5357) (Bug#9618)
13983 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13985 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13986 errors in XSetWindowBorder (bug#9310).
13988 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13990 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13991 avoid crash when xmalloc overrun checking is enabled.
13993 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13995 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13996 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13997 cursor motion with <left> and <right> arrow keys.
13999 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14000 some callers set that themselves.
14002 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14004 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14005 display string and the previous row comes from the same string and
14006 is empty. (Bug#9739) (Bug#9738)
14008 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14010 * doc.c (get_doc_string): Encode file name (bug#9735).
14012 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14014 * bidi.c (bidi_level_of_next_char):
14015 * xdisp.c (get_visually_first_element): Remove old incorrect
14016 comments regarding the Unicode Line Separator character.
14018 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14020 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14022 * alloc.c (Fgc_status): Do not access beyond zombies array
14023 boundary if nzombies > MAX_ZOMBIES.
14024 * alloc.c (dump_zombies): Add missing format specifier.
14026 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14028 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14029 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14031 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14032 Some packages use them to denote characters with modifiers.
14034 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14036 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14037 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14038 matching a pp-number. Rename parameter var to var1.
14040 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14042 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14044 2011-10-08 Glenn Morris <rgm@gnu.org>
14046 * callint.c (Fcall_interactively): Give a more explicit error for the
14047 'c' case with a non-character input. (Bug#8479)
14049 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14051 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14053 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14054 lines that are hscrolled on the left.
14056 * dispnew.c (buffer_posn_from_coords): Account for a possible
14057 presence of header-line. (Bug#4426)
14059 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14061 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14062 Don't advertise functionality which we discourage or doesn't work.
14064 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14066 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14067 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14068 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14069 this makes Emacs dump core during garbage collection on rare
14070 occasions. sizeof is obviously inferior to offsetof here, so
14071 stick with offsetof.
14072 (GC_POINTER_ALIGNMENT): New macro.
14073 (mark_memory): Omit 3rd (offset) arg; caller changed.
14074 Don't assume EMACS_INT alignment is the same as pointer alignment.
14076 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14078 * keyboard.c (read_key_sequence_remapped): New var.
14079 (read_key_sequence): Compute remapping in the right buffer.
14080 (command_loop_1): Use read_key_sequence's remapping directly.
14082 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14084 * dired.c (file_name_completion): Don't expand file name.
14085 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14086 before checking file name handler.
14088 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14089 they've been requested explicitly (bug#9591).
14091 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14093 * keymap.c (Fsingle_key_description): Use make_specified_string
14094 instead of build_string to build string from push_key_description.
14097 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14099 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14100 This fixes a Y2038 bug on 64-bit hosts.
14101 * buffer.c (reset_buffer):
14102 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14103 (Fclear_buffer_auto_save_failure):
14104 Use 0, not -1, to represent an unset failure time, since time_t
14105 might not be signed.
14107 Remove dependency on glibc malloc internals.
14108 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14109 Move back here from lisp.h, but with their new implementations.
14110 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14111 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14112 * charset.c (charset_table_init): New static var.
14113 (syms_of_charset): Use it instead of xmalloc. This removes a
14114 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14115 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14116 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14117 Move back to alloc.c.
14118 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14119 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14121 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14123 * nsterm.m (windowDidResize): Call x_set_window_size only when
14124 ns_in_resize is true. Otherwise set pixelwidth/height and
14125 call change_frame_size (Bug#9628).
14127 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14129 Port --enable-checking=all to Fedora 14 x86-64.
14130 * charset.c (syms_of_charset): Also account for glibc malloc's
14131 internal overhead when calculating the initial malloc maximum.
14133 Port --enable-checking=all to Fedora 14 x86.
14134 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14136 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14137 (overrun_check_realloc, overrun_check_free):
14138 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14139 That way, xmalloc returns a properly-aligned pointer even if
14140 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14141 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14142 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14143 into account when calculating the initial malloc maximum.
14144 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14145 Move here from alloc.c, so that charset.c can use it too.
14146 Properly align; the old code wasn't right for common 32-bit hosts
14147 when configured with --enable-checking=all.
14148 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14149 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14151 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14153 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14156 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14158 * xdisp.c (compute_display_string_end): If there's no display
14159 string at CHARPOS, return -1.
14161 * bidi.c (bidi_fetch_char): When compute_display_string_end
14162 returns a negative value, treat the character as a normal
14163 character not covered by a display string. (Bug#9624)
14165 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14167 * lread.c (Fread_from_string): Fix typo in docstring.
14169 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14171 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14172 newline, reseat the iterator instead of bidi-iterating there one
14173 character at a time. (Bug#9610)
14174 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14175 TO_CHARPOS if the bidi iterator is at base embedding level.
14177 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14179 * lread.c (readevalloop): Use correct code for NBSP.
14180 (read1): Likewise. (Bug#9608)
14182 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14184 * dbusbind.c (Fdbus_register_signal): When service is not
14185 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14187 2011-09-25 Glenn Morris <rgm@gnu.org>
14189 * buffer.c (truncate-lines): Doc fix.
14191 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14193 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14194 (Fset_window_next_buffers): Doc fix.
14196 2011-09-24 Glenn Morris <rgm@gnu.org>
14198 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14200 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14202 Fix minor problems found by static checking.
14203 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14204 * indent.c (Fvertical_motion): Fix == vs = typo.
14206 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14208 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14209 Default value is now t. Doc fix.
14211 * indent.c (Fvertical_motion): Compute and apply the overshoot
14212 logic when moving up, not only when moving down. Fix the
14213 confusing name and values of the it_overshoot_expected variable;
14214 logic changes accordingly. (Bug#9254) (Bug#9549)
14216 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14217 CHARPOS is covered by a display string which includes newlines.
14218 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14219 is covered by a display string with embedded newlines.
14221 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14223 * dbusbind.c (Fdbus_register_signal): Add match rule to
14224 Vdbus_registered_objects_table. (Bug#9581)
14225 (Fdbus_register_method, Vdbus_registered_objects_table):
14228 2011-09-24 Jim Meyering <meyering@redhat.com>
14230 do not ignore write error for any output size
14231 The previous change was incomplete.
14232 While it makes emacs --batch detect the vast majority of stdout
14233 write failures, errors were still ignored whenever the output size is
14234 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14235 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14236 && echo FAIL: ignored write error
14237 FAIL: ignored write error
14238 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14239 && echo FAIL: ignored write error
14240 FAIL: ignored write error
14241 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14243 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14245 * emacs.c (Fkill_emacs): In noninteractive mode exit
14246 non-successfully if a write error occurred on stdout. (Bug#9574)
14248 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14250 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14253 * dispextern.h (struct it): Update the comment documenting what
14256 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14258 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14259 a display string, extend search for cursor position to end of row.
14260 (find_row_edges): If the row ends in a newline from a display
14261 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14262 Handle the case of a display string with multiple newlines.
14263 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14264 non-empty line. Fixes confusing cursor motion with arrow keys at
14265 the beginning of a line that starts with whitespace.
14267 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14269 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14272 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14274 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14275 boolean (Bug#9154).
14277 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14279 * xdisp.c (display_line): Record maximum and minimum buffer
14280 positions even if no glyphs were produced (e.g., by a zero-width
14281 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14282 buffer positions that will be removed from the glyph row because
14284 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14285 column is beyond frame width: don't subtract 1 "pixel" when
14286 computing width of the stretch.
14287 (reseat_at_next_visible_line_start): Undo the change made on
14288 2011-09-17 that saved paragraph information and restored it after
14289 the call to `reseat'. (Bug#9545)
14291 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14293 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14294 and turn window cursor on if cleared (Bug#9415).
14296 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14298 * search.c (boyer_moore): Take unibyte characters from pattern
14299 literally. (Bug#9458)
14301 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14303 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14305 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14307 Fix minor problem found by static checking.
14308 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14309 initialized, to pacify gcc -Wuninitialized.
14311 * fileio.c: Report proper errno when syscall falls.
14312 (Finsert_file_contents): Save and restore errno,
14313 so that report_file_error outputs the correct diagnostic.
14314 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14316 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14318 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14320 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14322 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14323 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14325 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14327 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14328 about the current paragraph and restore it after the call to reseat.
14330 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14331 (bidi_find_paragraph_start): Search back for paragraph beginning
14332 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14333 (bidi_move_to_visually_next): Only trigger paragraph-related
14334 computations when the last character is a newline or at EOB, not
14335 just any NEUTRAL_B. (Bug#9470)
14337 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14338 truncated lines if point is covered by a display string. (Bug#9524)
14340 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14342 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14343 (cons_to_x_long): New function.
14344 (lisp_data_to_selection_data): Use it. Correct the test for
14345 short-versus-long data; it was negated. Break out of vector
14346 loop, for efficiency, when a long datum is discovered.
14348 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14350 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14352 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14354 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14355 GCC PR/17406) by declaring this function with external scope.
14357 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14359 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14360 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14362 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14364 * editfns.c (Fformat): Correctly handle text properties on "%%".
14366 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14368 * xterm.c (x_draw_composite_glyph_string_foreground):
14369 * w32term.c (x_draw_composite_glyph_string_foreground):
14370 * term.c (encode_terminal_code):
14371 * composite.c (composition_update_it, get_composition_id):
14372 * xdisp.c (get_next_display_element)
14373 (fill_composite_glyph_string): Add comments about special meaning
14374 of TAB characters in a composition.
14376 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14378 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14379 This occurs when processing a multibyte format.
14380 Problem reported by Wolfgang Jenker.
14382 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14384 * xdisp.c (try_cursor_movement): Only check for exact match if
14385 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14387 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14389 Remove unused external symbols.
14390 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14391 * xdisp.c (calc_pixel_width_or_height): Now static.
14392 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14393 * indent.c (check_display_width):
14394 * w32term.c: Fix comment to match code.
14395 * xterm.c, xterm.h (x_catching_errors): Remove.
14397 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14399 * xselect.c: Use signed conversions more consistently (Bug#9498).
14400 (selection_data_to_lisp_data): Assume incoming selection data are
14401 signed integers, not unsigned. This is to be consistent with
14402 outgoing selection data, which was modified to use signed integers
14403 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14404 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14405 expects long, not unsigned long.
14407 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14409 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14410 computation of loop end. Reported by Johan Bockgård
14413 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14415 * frame.c (Fother_visible_frames_p): Function deleted.
14417 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14419 * indent.c (compute_motion): Process display vector front to back
14420 rather than the other way around. (Bug#2496)
14422 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14424 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14426 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14428 * minibuf.c (Fread_from_minibuffer): Doc fix.
14430 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14432 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14433 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14435 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14437 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14438 value for non-existent files.
14440 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14442 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14443 set its "size" to -1. This will set the modtime_size field of
14444 the corresponding buffer to -1, which is what
14445 verify-visited-file-modtime expects for files that do not exist.
14448 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14450 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14452 * lisp.h: ... from here. push_key_description is no longer
14453 defined in keyboard.c, so its declaration should not be in
14454 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14455 logically belongs with push_key_description.
14457 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14459 * buffer.h: Include <sys/types.h> instead of <time.h>.
14460 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14461 Problem reported by Herbert J. Skuhra.
14463 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14465 * xml.c (parse_region): Make the parsing work for
14466 non-comment-starting XML files again (bug#9144).
14468 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14470 * image.c (gif_load): Fix calculation of bottom and right corner.
14473 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14475 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14476 redisplay in small windows.
14478 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14480 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14482 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14484 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14485 Operate on live windows only.
14487 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14489 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14491 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14493 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14494 only under bidi iteration.
14496 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14498 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14500 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14502 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14503 Without this fix, the command to link temacs failed due to an
14504 undefined symbol __builtin_isnan. This is because
14505 /usr/include/iso/math_c99.h #defines isnan(x) to
14506 __builtin_isnan(x), but the bundled gcc, which identifies itself
14507 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14509 * floatfns.c (isnan): #undef, and then #define to a clone of
14511 (Fisnan): Always define, since it's always available now.
14512 (syms_of_floatfns): Always define isnan at the Lisp level.
14514 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14516 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14518 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14520 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14521 The previous code assumed that file offsets (off_t values) fit in
14522 EMACS_INT variables, which is not true on typical 32-bit hosts.
14523 The code messed up by falsely reporting buffer overflow in cases
14524 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14525 when "big" contains more than 2**29 bytes, even though this
14526 inserts just one byte and does not overflow the buffer.
14527 (Finsert_file_contents): Store file offsets as off_t
14528 values, not as EMACS_INT values. Check for overflow when
14529 converting between EMACS_INT and off_t. When checking for
14530 buffer overflow or for overlap, take the offsets into account.
14531 Don't use EMACS_INT for small values where int suffices.
14532 When checking for overlap, fix a typo: ZV was used where
14533 ZV_BYTE was intended.
14534 (Fwrite_region): Don't assume off_t fits into 'long'.
14535 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14537 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14539 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14541 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14543 sprintf-related integer and memory overflow issues (Bug#9412).
14545 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14546 (esprintf, exprintf, evxprintf): New functions.
14547 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14548 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14549 (modify_event_symbol): Do not assume that the length of
14550 name_alist_or_stem is safe to alloca and fits in int.
14551 (Fexecute_extended_command): Likewise for function name and binding.
14552 (Frecursion_depth): Wrap around reliably on integer overflow.
14553 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14554 since some callers pass EMACS_INT values.
14555 (Fsingle_key_description): Don't crash if symbol name contains more
14556 than MAX_ALLOCA bytes.
14557 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14558 (get_minibuffer): Arg is now EMACS_INT, not int.
14559 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14560 (esprintf, exprintf, evxprintf): New decls.
14561 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14563 * dbusbind.c (signature_cat): New function.
14564 (xd_signature, Fdbus_register_signal):
14565 Do not overrun buffer; instead, report string overflow.
14567 * dispnew.c (add_window_display_history): Don't overrun buffer.
14568 Truncate instead; this is OK since it's just a log.
14570 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14571 even if the time zone offset is outlandishly large.
14572 Don't mishandle offset == INT_MIN.
14574 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14575 when creating daemon; the previous buffer-overflow check was incorrect.
14577 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14578 which has the guts of the old verror function.
14580 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14581 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14583 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14584 (font_unparse_xlfd): Don't blindly alloca long strings.
14585 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14586 fits in int, when using sprintf. Use single snprintf to count
14587 length of string rather than counting it via multiple sprintfs;
14588 that's simpler and more reliable.
14589 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14590 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14591 sprintf, in case result does not fit in int.
14593 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14594 (fontset_from_font): Print it.
14596 * frame.c (tty_frame_count): Now printmax_t, not int.
14597 (make_terminal_frame, set_term_frame_name): Print it.
14598 (x_report_frame_params): In X, window IDs are unsigned long,
14599 not signed long, so print them as unsigned.
14600 (validate_x_resource_name): Check for implausibly long names,
14601 and don't assume name length fits in 'int'.
14602 (x_get_resource_string): Don't blindly alloca invocation name;
14603 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14606 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14607 (xg_check_special_colors, xg_set_geometry):
14608 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14610 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14611 Use esprintf, not sprintf, in case result does not fit in int.
14613 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14614 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14615 it as a large positive number.
14616 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14617 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14619 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14620 in case result does not fit in int.
14622 * print.c (float_to_string): Detect width overflow more reliably.
14623 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14624 buffer overrun. Don't assume list length fits in 'int'. Treat
14625 print length of 0 as 0, not as infinity; to be consistent with other
14626 uses of print length in this function. Don't overflow print length
14627 index. Don't assume hash table size fits in 'long', or that
14628 vectorlike size fits in 'unsigned long'.
14630 * process.c (make_process): Use printmax_t, not int, to format
14631 process-name gensyms.
14633 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14635 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14636 to avoid potential buffer overrun.
14638 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14639 if X resource line is longer than 512 bytes.
14641 * xfns.c (x_window): Make sprintf buffer a bit bigger
14642 to avoid potential buffer overrun.
14644 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14646 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14648 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14650 Integer overflow fixes for scrolling, etc.
14651 Without these, Emacs silently mishandles large integers sometimes.
14652 For example, "C-u 4294967297 M-x recenter" was treated as if
14653 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14655 * xdisp.c (try_window_id): Check Emacs fixnum range before
14656 converting to 'int'.
14658 * window.c (window_scroll_line_based, Frecenter):
14659 Check that an Emacs fixnum is in range before assigning it to 'int'.
14660 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14661 values converted from Emacs fixnums.
14662 (Frecenter): Don't wrap around a line count if it is out of 'int'
14663 range; instead, treat it as an extreme value.
14664 (Fset_window_configuration, compare_window_configurations):
14665 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14667 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14668 that can exceed INT_MAX. Check that EMACS_INT value is in range
14669 before assigning it to the (possibly-narrower) index.
14670 (match_limit): Don't assume that a fixnum can fit in 'int'.
14672 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14675 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14676 (Fvertical_motion): Don't wrap around LINES values that don't fit
14677 in 'int'. Instead, treat them as extreme values. This is good
14678 enough for windows, which can't have more than INT_MAX lines anyway.
14680 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14682 * Require libxml/parser.h to avoid compilation warning.
14684 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14686 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14687 since this reportedly can destroy thread storage.
14689 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14691 * syntax.c (find_defun_start): Update all cache variables if
14692 exiting early (Bug#9401).
14694 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14696 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14698 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14699 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14700 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14702 * term.c (tty_append_glyph): New function.
14703 (produce_stretch_glyph): Static function and its prototype deleted.
14705 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14708 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14710 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14711 when checking :margin (Bug#9390).
14712 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14713 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14714 so that the name doesn't mislead. All uses changed.

14724 position beyond to_charpos, if we are scanning backwards.
14725 (move_it_vertically_backward): When DY == 0, make sure we get to
14726 the first character in the line after the newline.
14728 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14730 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14731 (ccl_driver): Do not generate an out-of-range pointer.
14732 (Fccl_execute_on_string): Remove unnecessary check for
14733 integer overflow, noted by Stefan Monnier in
14734 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14735 Remove a FIXME that didn't need fixing.
14736 Simplify the newly-introduced buffer reallocation code.
14738 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14740 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14742 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14744 Integer and memory overflow issues (Bug#9196).
14746 * doc.c (get_doc_string): Rework so that
14747 get_doc_string_buffer_size is the actual buffer size, rather than
14748 being 1 less than the actual buffer size; this makes xpalloc more
14751 * image.c (x_allocate_bitmap_record, cache_image):
14752 * xselect.c (Fx_register_dnd_atom):
14753 Simplify previous changes by using xpalloc.
14755 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14756 since either will do and ptrdiff_t is convenient with xpalloc.
14758 * charset.c (charset_table_size)
14759 (struct charset_sort_data.priority): Now ptrdiff_t.
14760 (charset_compare): Don't overflow if priorities differ greatly.
14761 (Fsort_charsets): Don't assume list length fits in int.
14762 Check for size-calculation overflow when allocating sort data.
14763 (syms_of_charset): Allocate an initial charset table that is
14764 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14766 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14768 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14769 The actual value is always <= INT_MAX, and leaving it unsigned made
14770 overflow checking harder.
14772 * dispextern.h (struct glyph_matrix.rows_allocated)
14773 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14774 with xpalloc. The values are still always <= INT_MAX.
14776 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14778 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14779 (SAFE_NALLOCA): New macro.
14781 * region-cache.c (struct boundary.pos, find_cache_boundary)
14782 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14783 (set_cache_region, invalidate_region_cache)
14784 (revalidate_region_cache, know_region_cache, region_cache_forward)
14785 (region_cache_backward, pp_cache):
14786 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14787 so that ptrdiff_t * can be passed to xpalloc.
14788 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14789 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14790 (pp_cache): Don't assume cache_len fits in int.
14791 * region-cache.h: Adjust extern decls to match.
14793 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14794 EMACS_INT, since either will do, for xpalloc.
14796 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14797 (xnmalloc, xnrealloc, xpalloc): New functions.
14799 * bidi.c (bidi_shelve_header_size): New constant.
14800 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14801 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14803 * bidi.c (bidi_cache_shrink):
14804 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14806 Don't update size of array until after memory allocation succeeds,
14807 because xmalloc/xrealloc may not return.
14808 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14809 now that we have proper integer overflow checking.
14810 (record_overlay_string, overlay_strings): Catch overflows when
14811 calculating size of overlay_str_buf.
14813 * callproc.c (Fcall_process): Check for size overflow when
14814 calculating size of args2.
14815 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14816 Normally we prefer signed values, but sticking with ptrdiff_t would
14817 require adding more-complicated checks.
14819 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14820 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14821 Redo buffer-overflow calculations to avoid integer overflow.
14822 Add a FIXME comment where memory seems to be over-allocated.
14824 * character.c (Fstring): Check for size-calculation overflow.
14826 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14827 unnecessary integer overflow. Check for size overflow.
14828 (encode_coding_object): Don't update size until xmalloc succeeds.
14830 * composite.c (get_composition_id): Check for overflow in glyph
14831 length calculations.
14833 Integer and memory overflow fixes for display code.
14834 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14835 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14836 (scrolling_window): Check for overflow in size calculations.

14842 Don't update size until allocation succeeds.
14843 * fns.c (concat): Check for overflow in size calculations.
14844 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
14845 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

14848 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14849 (get_doc_string): Check for size calculation overflow.
14850 Don't update size until allocation succeeds.
14851 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14852 EMACS_INT, where ptrdiff_t will do.
14853 (Fsubstitute_command_keys): Check for string overflow.
14855 * editfns.c (set_time_zone_rule): Don't assume environment length
14857 (message_length): Now ptrdiff_t, not int.
14858 (Fmessage_box): Don't update size until allocation succeeds.
14859 Don't assume message length fits in int.
14860 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14862 * emacs.c (main): Do not reallocate argv, since there is a null at
14863 the end that can be overwritten, and this way there's no need to
14864 worry about size-calculation overflow.
14865 (sort_args): Check for size-calculation overflow.
14867 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14869 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
14871 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
14872 (x_set_scroll_bar_width, x_figure_window_size):
14873 Check for integer overflow.
14874 (x_set_alpha): Do not assume XINT fits in int.
14876 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14877 This is for the members text_lines, text_cols, total_lines, total_cols,
14878 where the system imposes an 'int' limit.
14880 * fringe.c (Fdefine_fringe_bitmap):
14881 Don't update size until alloc works.
14883 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14884 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14886 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14887 Check for size-calculation overflow.
14888 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14889 do, as we prefer signed integers.
14890 (id_to_widget.max_size, id_to_widget.used)
14891 (xg_store_widget_in_map, xg_remove_widget_from_map)
14892 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14893 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14894 Use and return ptrdiff_t, not int.
14895 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14896 * gtkutil.h: Change prototypes to match the above.
14898 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14899 are duplicate now that they've been promoted to lisp.h.
14900 (x_allocate_bitmap_record, x_alloc_image_color)
14901 (make_image_cache, cache_image, xpm_load):

14913 Use ptrdiff_t, not int, to count maps.
14914 (read_char_minibuf_menu_prompt): Check for overflow in size
14915 calculations. Don't update size until allocation succeeds.
14916 Redo calculations to avoid overflow.

14945 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14946 for command line length. Do not attempt to address one before the
14947 beginning of an array, as that's not portable.
14949 * term.c (max_frame_lines): Remove; unused.
14950 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14952 (encode_terminal_code, calculate_costs): Check for size
14953 calculation overflow.

14959 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
14960 subtracting pointers.
14961 (gobble_line): Check for overflow more carefully. Don't update size

14975 Use ptrdiff_t, not int, for sizes.
14976 (Finternal_make_lisp_face, cache_face):
14977 Check for size calculation overflow.
14978 (cache_face): Treat size calculation overflows as if they were
14979 memory exhaustion (the usual treatment), rather than aborting.
14981 * xfns.c (x_encode_text, x_set_name_internal)
14982 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14983 sizes, since they can exceed INT_MAX in size. Check for size

14987 (xg_select): Check for size calculation overflow.
14988 Don't update size until alloc done.
14990 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14991 as sprintf is limited to int lengths.
14993 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14994 (X_LONG_MIN): New macros.
14995 Use them to make the following changes clearer.
14996 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14997 This change doesn't affect the value now, but it may help remind
14998 future maintainers not to raise the value too much later.
14999 (SELECTION_QUANTUM): Remove, replacing with ...
15000 (selection_quantum): ... new function, which avoids overflow.
15002 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15003 assumption that selection length fits in 'int'.

15016 (lisp_data_to_selection_data, x_property_data_to_lisp):

15020 Don't store size until memory allocation succeeds.
15021 (x_get_window_property): Plug memory leak on memory exhaustion.
15022 Don't double-block input; malloc is safe here. Don't assume 2**34
15023 - 4 fits in unsigned long. Add an xassert to check
15024 XGetWindowProperty overflow. Be more careful about overflow
15025 calculations, and distinguish size from memory overflow better.

15027 unsigned int is less than INT_MAX.
15028 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
15029 harmful) conversions of unsigned short to int.
15030 (lisp_data_to_selection_data): Don't assume that integers
15031 in the range -65535 through -1 fit in an X unsigned short.
15032 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15033 result parameters unless successful. Rely on cons_to_unsigned
15034 to report problems with elements; the old code wasn't right anyway.
15035 (x_check_property_data): Check for int overflow; we cannot use
15036 a wider type due to X limits.
15037 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

15069 * lisp.h (hash_lookup, hash_put):
15070 * minibuf.c (Ftest_completion):
15071 Use ptrdiff_t for hash table indexes, not int (which is too
15072 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15073 32-bit --with-wide-int hosts).
15075 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15076 Add a FIXME comment about memory leaks.
15077 (syms_of_charset): Don't assume xmalloc returns.

15084 with outlandish widths.
15085 * character.h (sanitize_tab_width): Rename from sanitize_width,
15086 now that we have two such functions. All uses changed.

15107 exceed limits imposed by XClientMessageEvent, as well as the usual
15108 ptrdiff_t and size_t limits.
15110 * keyboard.c: Overflow, signedness and related fixes.
15111 (make_lispy_movement): Use same integer type in forward decl
15112 that is used in the definition.
15113 (read_key_sequence, keyremap_step):
15114 Change bufsize argument back to int, undoing my 2011-03-30 change.
15115 We prefer signed types, and int is wide enough here.
15116 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15117 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15118 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15119 length, not size_t. Use ptrdiff_t for index, not int.
15120 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15121 possibility of integer overflow.
15123 Overflow, signedness and related fixes for images.

15146 (xbm_image_p): Locals are now of int, not EMACS_INT,
15147 since parse_image_check makes sure they fit into int.
15148 (png_load, gif_load, svg_load_image):
15149 Prefer int to unsigned where either will do.
15150 (tiff_handler): New function, combining the cores of the
15151 old tiff_error_handler and tiff_warning_handler.
15152 This function is rewritten to use vsnprintf and thereby avoid
15153 stack buffer overflows. It uses only the features of vsnprintf
15154 that are common to both POSIX and native Microsoft.
15155 (tiff_error_handler, tiff_warning_handler): Use it.
15156 (tiff_load, gif_load, imagemagick_load_image):
15157 Don't assume :index value fits in 'int'.
15158 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15159 (imagemagick_load_image): Check that crop parameters fit into
15160 the integer types that MagickCropImage accepts. Don't assume
15161 Vimagemagick_render_type has a nonnegative value. Don't assume
15162 size_t fits in 'long'.
15163 (gs_load): Use printmax_t to print the widest integers possible.
15164 Check for integer overflow when computing image height and width.
15166 2011-08-26 Eli Zaretskii <eliz@gnu.org>
15168 * xdisp.c (redisplay_window): Don't force window start if point

15177 (handle_single_display_spec): If the display spec is of the form
15178 `(space ...)', and specifies display in the text area, return 2
15180 (try_cursor_movement): Check for the need to scroll more
15181 accurately, and prefer exact match for point under bidi.
15182 Don't advance `row' beyond the last row of the window.
15184 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
15185 into disp_prop; all users changed.

15200 buffers, return left-to-right.
15201 (set_cursor_from_row): Consider candidate row a win if its glyph
15202 represents a newline and point is on that newline. Fixes cursor
15203 positioning on the newline at EOL of R2L text within L2R
15204 paragraph, and vice versa.
15205 (try_cursor_movement): Check continued rows, in addition to
15206 continuation rows. Fixes unwarranted scroll when point enters a
15207 continued line of R2L text within an L2R paragraph, or vice versa.
15208 (cursor_row_p): Consider the case of point being equal to
15209 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15210 from the end of a short line to the beginning of a continued line
15211 of R2L text within L2R paragraph.

15233 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15235 * xdisp.c (redisplay_window): When computing centering_position,
15236 account for the height of the header line. (Bug#8874)
15238 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15239 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15240 candidate is selected by the mouse, and that candidate has a
15241 composed character under the mouse.
15243 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15244 coordinates reported by pos-visible-in-window-p for a composed
15245 character in column zero.
15247 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

15254 consider it a hit if to_charpos is anywhere in the range of the
15255 composed buffer positions.
15257 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15259 * image.c (gif_load): Don't assume that each subimage has the same
15260 dimensions as the base image. Handle disposal method that is
15261 "undefined" by the gif spec (Bug#9335).
15263 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15265 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15270 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15271 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15272 from an Org mode buffer to a Speedbar frame.
15274 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15275 a composition, take its buffer position from IT->cmp_it.charpos.
15276 Fixes cursor positioning at the beginning of a line that begins
15277 with a composed character.
15279 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15281 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15282 character bidirectional type, use STRONG_L instead. Fixes crashes
15283 in a buffer produced by `describe-categories'.
15285 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15286 members before the level stack, so they would be saved and
15287 restored when copying iterator state. Fixes incorrect reordering
15288 around TABs covered by display properties.
15290 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15292 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15378 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15379 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15380 the event loop (Bug#7276).

15406 (Fnetwork_interface_list): Allocate in increments of bytes instead
15407 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15408 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct

15422 entry. Force push_it to save on the stack the current
15423 buffer/string position, to be restored by pop_it. Fix flags in
15424 the iterator structure wrt the object coming from a display
15425 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15426 properties. (Bug#9284)
15428 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>

15474 is non-zero, even if the data buffer is NULL. Fixes a crash in
15475 vertical-motion with longlines-mode. (Bug#9254)
15477 2011-08-05 Eli Zaretskii <eliz@gnu.org>

15617 * nsterm.h (nsfont_info): Remove voffset field.
15619 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15621 Implement strike-through and overline on NextStep (Bug#8863).
15623 * nsfont.m (nsfont_open): Use underline position provided by font,
15624 instead of hard-coded value of 2.
15625 (nsfont_draw): Call ns_draw_text_decoration instead.
15627 * nsterm.h: Add declaration for ns_draw_text_decoration.
15629 * nsterm.m (ns_draw_text_decoration): New function for drawing
15630 underline, overline, and strike-through.
15631 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15632 ns_draw_text_decoration. Change treatment of cursor drawing to
15633 accommodate underlining, etc.
15635 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15637 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15640 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15642 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15643 Without this fix, if a signal arrives just after memory fills up,
15644 'malloc' might be invoked reentrantly.
15646 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15647 In other words, assume that every image size is allowed, on non-X
15648 hosts. This assumption is probably wrong, but it lets Emacs compile.
15650 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15652 * regex.c (re_iswctype): Convert return values to boolean.
15654 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15656 * xdisp.c (compute_display_string_pos): Don't use cached display
15657 string position if the buffer had its restriction changed.
15660 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15662 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15664 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15666 Integer signedness and overflow and related fixes. (Bug#9079)
15668 * bidi.c: Integer size and overflow fixes.
15669 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15670 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15671 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15672 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15673 (bidi_find_other_level_edge):
15674 Use ptrdiff_t instead of EMACS_INT where either will do.
15675 This works better on 32-bit hosts configured --with-wide-int.
15676 (bidi_cache_ensure_space): Check for size-calculation overflow.
15677 Use % rather than repeated addition, for better worst-case speed.
15678 Don't set bidi_cache_size until after xrealloc returns, because it
15680 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15681 (bidi_cache_ensure_space): Also check that the bidi cache size
15682 does not exceed that of the largest Lisp string or buffer. See Eli
15683 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15685 * alloc.c (__malloc_size_t): Remove.
15686 All uses replaced by size_t. See Andreas Schwab's note
15687 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15689 * image.c: Improve checking for integer overflow.
15690 (check_image_size): Assume that f is nonnull, since
15691 it is always nonnull in practice. This is one less thing to
15692 worry about when checking for integer overflow later.
15693 (x_check_image_size): New function, which checks for integer
15694 overflow issues inside X.
15695 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15696 This removes the need for a memory_full check.
15697 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15698 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15699 (xbm_read_bitmap_data): Change locals back to 'int', since
15700 their values must fit in 'int'.
15701 (xpm_load_image, png_load, tiff_load):
15702 Invoke x_create_x_image_and_pixmap earlier,
15703 to avoid much needless work if the image is too large.
15704 (tiff_load): Treat overly large images as if
15705 x_create_x_image_and_pixmap failed, not as malloc failures.
15706 (gs_load): Use x_check_image_size.
15708 * gtkutil.c: Omit integer casts.
15709 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15710 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15712 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15714 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15715 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15716 would wrongly return t on a 64-bit host.
15718 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15719 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15720 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15721 and therefore cause GCC to emit a bogus diagnostic in some cases.
15723 * image.c: Integer signedness and overflow and related fixes.
15724 This is not an exhaustive set of fixes, but it's time to
15725 record what I've got.
15726 (lookup_pixel_color, check_image_size): Remove redundant decls.
15727 (check_image_size): Don't assume that arbitrary EMACS_INT values
15728 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15729 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15730 (tiff_load, imagemagick_load_image):
15731 Check for overflow in size calculations.
15732 (x_create_x_image_and_pixmap): Remove unnecessary test for
15733 xmalloc returning NULL; that can't happen.
15734 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15735 (xpm_color_bucket): Use better integer hashing function.
15736 (xpm_cache_color): Don't possibly over-allocate memory.
15737 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15738 (gif_memory_source):
15739 Use ptrdiff_t, not int or size_t, to record sizes.
15740 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15741 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15742 either works, as we prefer signed integers.
15743 (tiff_read_from_memory, tiff_write_from_memory):
15744 Return tsize_t, not size_t, since that's what the TIFF API wants.
15745 (tiff_read_from_memory): Don't fail simply because the read would
15746 go past EOF; instead, return a short read.
15747 (tiff_load): Omit no-longer-needed casts.
15748 (Fimagemagick_types): Don't assume size fits into 'int'.
15750 Improve hashing quality when configured --with-wide-int.
15751 * fns.c (hash_string): New function, taken from sxhash_string.
15752 Do not discard information about ASCII character case; this
15753 discarding is no longer needed.
15754 (sxhash-string): Use it. Change sig to match it. Caller changed.
15755 * lisp.h: Declare it.
15756 * lread.c (hash_string): Remove, since we now use fns.c's version.
15757 The fns.c version returns a wider integer if --with-wide-int is
15758 specified, so this should help the quality of the hashing a bit.
15760 * emacs.c: Integer overflow minor fix.
15761 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15762 Define only if GNU_LINUX.
15763 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15765 * dispnew.c: Integer signedness and overflow fixes.
15766 Remove unnecessary forward decls, that were a maintenance hassle.
15767 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15769 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15770 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15771 (prepare_desired_row, line_draw_cost):
15772 Use int, not unsigned, where either works.
15773 (save_current_matrix, restore_current_matrix):
15774 Use ptrdiff_t, not size_t, where either works.
15775 (init_display): Check for overflow more accurately, and without
15776 relying on undefined behavior.
15778 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15779 Remove, replacing with the new symbols in lisp.h. All uses changed.
15780 * fileio.c (make_temp_name):
15781 * filelock.c (lock_file_1, lock_file):
15782 * xdisp.c (message_dolog):
15783 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15784 Use pMd etc. instead.
15785 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15786 replacing the pWIDE etc. symbols removed from editfns.c.
15788 * keyboard.h (num_input_events): Now uintmax_t.
15789 This is (very slightly) less likely to mess up due to wraparound.
15792 * buffer.c: Integer signedness fixes.
15793 (alloc_buffer_text, enlarge_buffer_text):
15794 Use ptrdiff_t rather than size_t when either will do, as we prefer
15797 * alloc.c: Integer signedness and overflow fixes.
15798 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15799 (__malloc_size_t): Default to size_t, not to int.
15800 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15801 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15802 Prefer ptrdiff_t to size_t when either would do, as we prefer
15804 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15805 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15806 Now const. Initialize with values that are in range even if char
15808 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15809 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15810 These functions do the right thing with sizes > 2**32.
15811 (check_depth): Now ptrdiff_t, not int.
15812 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15813 Adjust to new way of storing sizes. Check for size overflow bugs
15815 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15816 slightly wrong anyway, as it missed one instance of
15817 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15818 (refill_memory_reserve): Omit needless cast to size_t.
15819 (mark_object_loop_halt): Mark as externally visible.
15821 * xselect.c: Integer signedness and overflow fixes.
15822 (Fx_register_dnd_atom, x_handle_dnd_message):
15823 Use ptrdiff_t, not size_t, since we prefer signed.
15824 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15825 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15826 x_dnd_atoms_size and x_dnd_atoms_length.
15828 * doprnt.c: Prefer signed to unsigned when either works.
15830 * doprnt.c (doprnt):
15832 * xdisp.c (vmessage):
15833 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15834 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15835 prefer signed arithmetic to avoid comparison confusion.
15836 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15837 but is a bit tricky.
15839 Assume freestanding C89 headers, string.h, stdlib.h.
15840 * data.c, doprnt.c, floatfns.c, print.c:
15841 Include float.h unconditionally.
15842 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15843 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15844 * regex.c: Likewise for stddef.h, string.h.
15845 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15846 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15847 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15848 (STDC_HEADERS): Remove obsolete defines.
15849 * sysdep.c: Include limits.h unconditionally.
15851 Assume support for memcmp, memcpy, memmove, memset.
15852 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15853 * regex.c (memcmp, memcpy):
15854 Remove; we assume C89 now.
15856 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15857 (__malloc_safe_bcopy): Remove; no longer needed.
15859 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15860 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15861 well either way, and we prefer signed to unsigned.
15863 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15865 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15866 closes the connection while we're reading (bug#9182).
15868 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15870 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15871 are specified (Bug#9168).
15873 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15875 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15876 Found by GCC static checking and --with-wide-int on a 32-bit host.
15878 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15880 * xdisp.c (compute_display_string_pos): Fix logic of caching
15881 previous display string position. Initialize cached_prev_pos to
15882 -1. Fixes slow-down at the beginning of a buffer.
15884 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15886 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15887 for attrs[LFACE_FONTSET_INDEX].
15889 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15891 * xml.c (parse_region): Remove unused local
15892 that was recently introduced.
15894 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15896 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15897 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15899 * xdisp.c (move_it_in_display_line_to): Record the best matching
15900 position for TO_CHARPOS while scanning the line, and restore it on
15901 exit if none of the characters scanned was an exact match.
15902 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15903 when exact match is impossible due to invisible text, and the
15904 lines are truncated.
15906 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15908 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15911 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15913 Fix a significant slow-down of cursor motion with C-n, C-p,
15914 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15915 auto-repeat under bidi redisplay in fontified buffers.
15916 * xdisp.c (compute_stop_pos_backwards): New function.
15917 (next_element_from_buffer): Call compute_stop_pos_backwards to
15918 find a suitable prev_stop when we find ourselves before
15920 (reseat): Don't look for prev_stop, as that could mean a very long
15922 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15923 <cached_disp_overlay_modiff>: Cache for last found display string
15925 (compute_display_string_pos): Return the cached position if asked
15926 about the same buffer in the same area of character positions, and
15927 the buffer wasn't changed since the time the display string
15928 position was cached.
15930 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15932 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15933 is an integer, which is important for empty lines. (Bug#9149)
15935 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15937 * frame.c (Fmodify_frame_parameters): In tty case, update the
15938 default face if necessary (Bug#4238).
15940 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15942 * editfns.c (Fstring_to_char): No need to explain what a character
15943 is in the docstring (Bug#6576).
15945 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15947 * xml.c (parse_region): Make sure we always return a tree.
15949 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15951 * xml.c (parse_region): If a document contains only comments,
15954 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15956 * xml.c (make_dom): Return comments, too.
15958 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15961 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15962 and the surrounding thread.
15963 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15964 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15965 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15967 * s/openbsd.h (BROKEN_SIGIO): Define.
15968 * unexelf.c (unexec) [__OpenBSD__]:
15969 Don't update the .mdebug section of the Alpha COFF symbol table.
15971 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15973 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15976 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15978 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15979 This fixes some race conditions on the permissions of any newly
15982 * alloc.c (valid_pointer_p): Use pipe, not open.
15983 This fixes some permissions issues when debugging.
15985 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15986 If fchown fails to set both uid and gid, try to set just gid,
15987 as that is sometimes allowed. Adjust the file's mode to eliminate
15988 setuid or setgid bits that are inappropriate if fchown fails.
15990 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15992 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15993 to compare Lisp_Objects.
15994 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15995 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15996 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15998 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16000 * lread.c (read_integer): Unread even EOF character.
16001 (read1): Likewise. Properly record start position of symbol.
16003 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16004 symbol character follows.
16006 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16008 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16009 This works around a problem with the previous change to Fcopy_file.
16010 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16011 and without this change, GCC might complain about discarding
16012 fchown's return value.
16014 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16016 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16018 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16020 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16022 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16024 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16025 it's used from the C level.
16027 * process.c: Use the same condition for POLL_FOR_INPUT in both
16028 keyboard.c and process.c (bug#1858).
16030 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16032 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16033 (Fgnutls_boot): Use it.
16035 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16037 * doc.c (Fsubstitute_command_keys): Revert last change.
16039 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16041 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16042 quotes the next character, and doesn't affect other longer
16043 sequences (bug#8935).
16045 * lread.c (syms_of_lread): Clarify that is isn't only
16046 `eval-buffer' and `eval-defun' that's affected by
16047 `lexical-binding' (bug#8460).
16049 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16051 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16052 bidi redisplay when a line includes both an image and is truncated.
16054 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16056 Fix minor problems found by static checking.
16057 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16058 (elsz): Now a signed constant, not a size_t var. We prefer signed
16059 types to unsigned, to avoid integer comparison confusion. Without

16110 the iterator is before prev_stop.

16592 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

16629 Random fixes. E.g., (random) never returned negative values.
16630 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16631 subseconds part to the entropy, as that's a bit more random.
16632 Prefer signed to unsigned, since the signedness doesn't matter and
16633 in general we prefer signed. When given a limit, use a
16634 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16635 latter isn't right if USE_2_TAGS_FOR_INTS.
16636 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16637 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16654 * buffer.c (Foverlay_put): Say what the return value is
16657 * fileio.c (barf_or_query_if_file_exists): Check first if the file

16661 error be more correct.
16663 * fns.c (Frequire): Remove the mention of the .gz files, since

16677 Qgnutls_bootprop_verify_error (which is no longer used).
16679 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16680 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16681 Also (re)move comments that are misplaced or no longer relevant.

16782 * eval.c (struct backtrace): Simplify and port the data structure.
16783 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16784 signed bit field, as this assumption is not portable and it makes
16785 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16786 "char debug_on_exit : 1" as this is not portable either; instead,
16787 use the portable "unsigned int debug_on_exit : 1". Remove unused
16788 member evalargs. Remove obsolete comments about cc bombing out.
16790 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16936 * terminal.c (syms_of_terminal):
16937 * textprop.c (syms_of_textprop):

16944 * xmenu.c (syms_of_xmenu):
16945 * xsettings.c (syms_of_xsettings):
16946 * xterm.c (syms_of_xterm): Use DEFSYM.
16948 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
16950 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
16952 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
16954 Integer and buffer overflow fixes (Bug#8873).
16956 * print.c (printchar, strout): Check for string overflow.
16957 (PRINTPREPARE, printchar, strout):
16958 Don't set size unless allocation succeeds.
16960 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16961 for sizes. Check for string overflow more accurately.
16962 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
16964 * macros.c: Integer and buffer overflow fixes.
16965 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16966 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
16967 Use ptrdiff_t, not int, for sizes.
16968 Don't increment bufsize until after realloc succeeds.
16969 Check for size-calculation overflow.
16970 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16972 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16974 * lread.c: Integer overflow fixes.
16975 (read_integer): Radix is now EMACS_INT, not int,
16976 to improve quality of diagnostics for out-of-range radices.
16977 Calculate buffer size correctly for out-of-range radices.
16978 (read1): Check for integer overflow in radices, and in
16979 read-circle numbers.
16980 (read_escape): Avoid int overflow.
16981 (Fload, openp, read_buffer_size, read1)
16982 (substitute_object_recurse, read_vector, read_list, map_obarray):
16983 Use ptrdiff_t, not int, for sizes.
16984 (read1): Use EMACS_INT, not int, for sizes.
16985 Check for size overflow.
16987 * image.c (cache_image): Check for size arithmetic overflow.
16989 * lread.c: Integer overflow issues.
16990 (saved_doc_string_size, saved_doc_string_length)
16991 (prev_saved_doc_string_size, prev_saved_doc_string_length):
16992 Now ptrdiff_t, not int.
16993 (read1): Don't assume doc string length fits in int. Check for
16994 out-of-range doc string lengths.
16995 (read_list): Don't assume file position fits in int.
16996 (read_escape): Check for hex character overflow.
16998 2011-06-22 Leo Liu <sdl.web@gmail.com>
17000 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
17001 Move to minibuffer.el.
17003 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17005 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17006 The following patches are for when GLYPH_DEBUG && !XASSERT.
17007 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17008 * dispnew.c (flush_stdout):
17009 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17010 Mark as externally visible.
17011 * dispnew.c (check_window_matrix_pointers): Now static.
17012 * dispnew.c (window_to_frame_vpos):
17013 * xfns.c (unwind_create_frame):
17014 * xterm.c (x_check_font): Remove unused local.
17015 * scroll.c (CHECK_BOUNDS):
17016 * xfaces.c (cache_fache): Rename local to avoid shadowing.
17017 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
17018 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
17019 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
17020 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
17022 (debug_method_add): Use va_list and vsprintf rather than relying
17023 on undefined behavior with wrong number of arguments.
17024 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17025 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17026 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17027 since we're not interested in debugging glyphs with old libraries.
17028 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17029 GCC 4.6.0's static checking.
17031 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17033 Integer overflow and signedness fixes (Bug#8873).
17034 A few related buffer overrun fixes, too.

17042 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
17043 (x_create_bitmap_from_xpm_data):
17044 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
17045 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
17047 * xfaces.c (load_pixmap):
17048 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17049 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17050 (.bitmaps_last, struct x_output.icon_bitmap):
17051 Use ptrdiff_t, not int, for bitmap indexes.
17052 (x_allocate_bitmap_record): Check for size overflow.
17053 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17055 Use ptrdiff_t, not int, for overlay counts.
17056 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17057 * editfns.c (overlays_around, get_pos_property):
17058 * textprop.c (get_char_property_and_overlay):
17059 * xdisp.c (next_overlay_change, note_mouse_highlight):
17060 * xfaces.c (face_at_buffer_position):
17061 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17062 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17063 (Fnext_overlay_change, Fprevious_overlay_change)
17064 (mouse_face_overlay_overlaps, Foverlays_in):
17065 Use ptrdiff_t, not int, for sizes.
17066 (overlays_at, overlays_in): Check for size-calculation overflow.
17068 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17070 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17071 (x_session_initialize): Do not assume string length fits in int.
17073 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17074 This is unlikely, but can occur if DPI is outlandish.
17076 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17077 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17079 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17080 * xrdb.c (magic_file_p, search_magic_path):
17081 Omit last arg SUFFIX; it was always 0. All callers changed.
17082 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17084 * xfont.c (xfont_match): Avoid need for strlen.
17086 * xfns.c: Don't assume strlen fits in int.
17087 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
17089 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17090 not unsigned long, as we prefer signed integers. All callers changed.
17091 Detect integer overflow in repeat count.
17092 (message_dolog): Don't assume print length fits in 39 bytes.
17093 (display_mode_element): Don't assume strlen fits in int.
17095 * termcap.c: Don't assume sizes fit in int and never overflow.
17096 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17097 (gobble_line): Check for size-calculation overflow.
17099 * minibuf.c (Fread_buffer):
17100 * lread.c (intern, intern_c_string):
17101 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17102 Don't assume string length fits in int.
17104 * keyboard.c (parse_tool_bar_item):
17105 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17107 * font.c: Don't assume string length fits in int.
17108 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17109 Use ptrdiff_t, not int.
17110 (font_intern_prop): Don't assume string length fits in int.
17111 Don't assume integer property fits in fixnum.
17112 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17114 * filelock.c: Fix some buffer overrun and integer overflow issues.
17115 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17116 Reformulate so as not to need the command string.
17117 Invoke gzip -cd rather than gunzip, as it's more portable.
17118 (lock_info_type, lock_file_1, lock_file):
17119 Don't assume pid_t and time_t fit in unsigned long.
17120 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17121 (current_lock_owner): Prefer signed type for sizes.
17122 Use memcpy, not strncpy, where memcpy is what is really wanted.
17123 Don't assume (via atoi) that time_t and pid_t fit in int.
17124 Check for time_t and/or pid_t out of range, e.g., via a network share.
17125 Don't alloca where an auto var works fine.
17127 * fileio.c: Fix some integer overflow issues.
17128 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17129 Don't assume string length fits in int.
17130 (directory_file_name): Don't assume string length fits in long.
17131 (make_temp_name): Don't assume pid fits in int, or that its print
17132 length is less than 20.
17134 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17136 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17138 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17140 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17141 We prefer signed integers, even for size calculations.
17143 * emacs.c: Don't assume string length fits in 'int'.
17144 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17145 (main): Don't invoke strlen when not needed.
17147 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17148 (XD_DEBUG_MESSAGE): Don't waste a byte.
17150 * callproc.c (getenv_internal_1, getenv_internal)
17151 (Fgetenv_internal):
17152 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17154 * lread.c (invalid_syntax): Omit length argument.
17155 All uses changed. This doesn't fix a bug, but it simplifies the
17156 code away from its former Hollerith-constant appearance, and it's
17157 one less 'int' to worry about when looking at integer-overflow issues.
17158 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17160 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17161 This didn't break anything, but it didn't help either.
17162 It's confusing to put a bogus integer in a place where the actual
17163 value does not matter.
17164 (LIST_END_P): Remove unused macro and its bogus comment.
17165 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17167 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17168 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17170 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17171 We prefer signed types, and the value cannot exceed the EMACS_INT
17172 range anyway (because otherwise the length would not be representable).
17173 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17174 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17175 This avoids a GCC warning when WIDE_EMACS_INT.
17177 * indent.c (sane_tab_width): New function.
17178 (current_column, scan_for_column, Findent_to, position_indentation)
17179 (compute_motion): Use it. This is just for clarity.
17180 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17182 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17184 * lisp.h (lint_assume): New macro.
17185 * composite.c (composition_gstring_put_cache):
17186 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17188 * editfns.c, insdel.c:
17189 Omit unnecessary forward decls, to simplify future changes.
17191 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17193 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17195 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17196 Use much-faster test for byte-length change.
17197 Don't assume string byte-length fits in 'int'.
17198 Check that character arg fits in 'int'.
17199 (mapcar1): Declare byte as byte, for clarity.
17201 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17203 * fns.c (concat): Catch string overflow earlier.
17204 Do not rely on integer wraparound.
17206 * dispextern.h (struct it.overlay_strings_charpos)
17207 (struct it.selective): Now EMACS_INT, not int.
17208 * xdisp.c (forward_to_next_line_start)
17209 (back_to_previous_visible_line_start)
17210 (reseat_at_next_visible_line_start, next_element_from_buffer):
17211 Don't arbitrarily truncate the value of 'selective' to int.
17213 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17215 * composite.c: Don't truncate sizes to 'int'.
17216 (composition_gstring_p, composition_reseat_it)
17217 (composition_adjust_point): Use EMACS_INT, not int.
17218 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17219 not EMACS_UINT, for indexes.
17221 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17223 * buffer.c: Include <verify.h>.
17224 (struct sortvec.priority, struct sortstr.priority):
17225 Now EMACS_INT, not int.
17226 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17227 (struct sortstr.size, record_overlay_string)
17228 (struct sortstrlist.size, struct sortlist.used):
17229 Don't truncate size to int.
17230 (record_overlay_string): Check for size-calculation overflow.
17231 (init_buffer_once): Check at compile-time, not run-time.
17233 2011-06-22 Jim Meyering <meyering@redhat.com>
17235 Don't leak an XBM-image-sized buffer
17236 * image.c (xbm_load): Free the image buffer after using it.
17238 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17241 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17242 that Sun C diagnosed.
17243 * fns.c (secure_hash): Fix pointer signedness issue.
17244 * intervals.c (static_offset_intervals): New function.
17245 (offset_intervals): Use it.
17247 2011-06-21 Leo Liu <sdl.web@gmail.com>
17250 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17253 * fns.c (secure_hash): Rename from crypto_hash_function and change
17254 the first arg to accept symbols.
17255 (Fsecure_hash): New primitive.
17256 (syms_of_fns): New symbols.
17258 2011-06-20 Deniz Dogan <deniz@dogan.se>
17260 * process.c (Fset_process_buffer): Clarify return value in
17263 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17265 * dispnew.c (add_window_display_history): Use BVAR.
17267 * xdisp.c (debug_method_add): Use BVAR.
17268 (check_window_end, dump_glyph_matrix, dump_glyph)
17269 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17271 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17274 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17275 check till after the cache is created in init_frame_faces.
17277 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17279 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17281 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17283 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17284 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17285 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17287 Improve buffer-overflow checking (Bug#8873).
17288 * fileio.c (Finsert_file_contents):
17289 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17290 Remove the old (too-loose) buffer overflow checks.
17291 They weren't needed, since make_gap checks for buffer overflow.
17292 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17293 The old code merely checked for Emacs fixnum overflow, and relied
17294 on undefined (wraparound) behavior. The new code avoids undefined
17295 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17297 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17298 Tune. Don't use wider integers than needed. Don't use alloca.
17299 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17301 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17303 * insdel.c, lisp.h (buffer_overflow): New function.
17304 (insert_from_buffer_1, replace_range, replace_range_2):
17305 * insdel.c (make_gap_larger):
17306 * editfns.c (Finsert_char):
17307 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17309 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17311 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17313 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17315 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17316 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17318 * fileio.c: Don't assume EMACS_INT fits in off_t.
17319 (emacs_lseek): New static function.
17320 (Finsert_file_contents, Fwrite_region): Use it.
17321 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17323 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17325 * fns.c: Don't overflow int when computing a list length.
17326 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17327 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17328 truncation on 64-bit hosts. Check for QUIT every
17329 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17330 faster and is responsive enough.
17331 (Flength): Report an error instead of overflowing an integer.
17332 (Fsafe_length): Return a float if the value is not representable
17333 as a fixnum. This shouldn't happen except in contrived situations.
17334 (Fnthcdr, Fsort): Don't assume list length fits in int.
17335 (Fcopy_sequence): Don't assume vector length fits in int.
17337 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17338 (header_size, word_size): New constants.
17339 (allocate_vectorlike): Don't check size overflow here.
17340 (allocate_vector): Check it here instead, since this is the only
17341 caller of allocate_vectorlike that could cause overflow.
17342 Check that the new vector's length is representable as a fixnum.
17344 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17345 The previous code was bogus. For example, next_almost_prime (32)
17346 returned 39, which is undesirable as it is a multiple of 3; and
17347 next_almost_prime (24) returned 25, which is a multiple of 5 so
17348 why was the code bothering to check for multiples of 7?
17350 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17352 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17354 Variadic C functions now count arguments with ptrdiff_t.
17355 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17356 Back then I didn't know that the Emacs coding style prefers signed int.
17357 Also, in the meantime I found a few more instances where arguments
17358 were being counted with int, which may truncate counts on 64-bit
17359 machines, or EMACS_INT, which may be unnecessarily wide.
17360 * lisp.h (struct Lisp_Subr.function.aMANY)
17361 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17362 Arg counts are now ptrdiff_t, not size_t.
17363 All variadic functions and their callers changed accordingly.
17364 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17365 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17366 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17367 * callint.c (Fcall_interactively): Check arg count for overflow,
17368 to avoid potential buffer overrun. Use signed char, not 'int',
17369 for 'varies' array, so that we needn't bother to check its size
17370 calculation for overflow.
17371 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17372 * eval.c (apply_lambda):
17373 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17374 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17375 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17377 * callint.c (Fcall_interactively): Don't use index var as event count.
17379 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17380 * mem-limits.h (SIZE): Remove; no longer used.
17382 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17384 Remove unnecessary casts.
17385 * xterm.c (x_term_init):
17386 * xfns.c (x_set_border_pixel):
17387 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17388 These aren't needed now that we assume ANSI C.
17390 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17391 It's more likely to cause problems (due to unsigned overflow)
17394 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17396 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17398 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17400 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17402 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17404 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17406 GLYPH_CODE_FACE returns EMACS_INT, not int.
17407 * dispextern.h (merge_faces):
17408 * xfaces.c (merge_faces):
17409 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17410 Don't assume EMACS_INT fits in int.
17412 * character.h (CHAR_VALID_P): Remove unused parameter.
17413 * fontset.c, lisp.h, xdisp.c: All uses changed.
17415 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17417 * fns.c (concat): Minor tuning based on overflow analysis.
17418 This doesn't fix any bugs. Use int to hold character, instead
17419 of constantly refetching from Emacs object. Use XFASTINT, not
17420 XINT, for value known to be a character. Don't bother comparing
17421 a single byte to 0400, as it's always less.
17423 * floatfns.c (Fexpt):
17424 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17426 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17429 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17431 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17432 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17433 incorrectly succeed when S was a string, because 4294967386 was
17434 truncated before it was used.
17436 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17437 Otherwise, an out-of-range integer could cause undefined behavior
17440 * composite.c: Use int, not EMACS_INT, for characters.
17441 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17442 EMACS_INT, for values that are known to be in character range.
17443 This doesn't fix any bugs but is the usual style inside Emacs and
17444 may generate better code on 32-bit machines.
17446 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17447 This is for reasons similar to the recent CHAR_STRING fix.
17448 * charset.c (Fencode_char): Check that character arg is actually
17449 a character. Pass an int to ENCODE_CHAR.
17450 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17451 wider than 'int', as a compile-time check to prevent future regressions
17454 * character.c (char_string): Remove unnecessary casts.
17456 Make sure a 64-bit char is never passed to CHAR_STRING.
17457 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17458 by silently ignoring the top 32 bits, allowing some values
17459 that were far too large to be valid characters.
17460 * character.h: Include <verify.h>.
17461 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17462 arguments are no wider than unsigned, as a compile-time check
17463 to prevent future regressions in this area.
17465 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17466 (Fsubst_char_in_region):
17468 * xdisp.c (decode_mode_spec_coding):
17469 Adjust to CHAR_STRING's new requirement.
17470 * editfns.c (Finsert_char, Fsubst_char_in_region):
17471 * fns.c (concat): Check that character args are actually
17472 characters. Without this test, these functions did the wrong
17473 thing with wildly out-of-range values on 64-bit hosts.
17475 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17476 These casts should not be needed on 32-bit hosts, either.
17477 * keyboard.c (read_char):
17478 * lread.c (Fload): Remove casts to unsigned.
17480 * lisp.h (UNSIGNED_CMP): New macro.
17481 This fixes comparison bugs on 64-bit hosts.
17482 (ASCII_CHAR_P): Use it.
17483 * casefiddle.c (casify_object):
17484 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17485 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17486 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17487 * dispextern.h (FACE_FROM_ID):
17488 * keyboard.c (read_char): Use UNSIGNED_CMP.
17490 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17491 not to EMACS_INT, to avoid GCC warning.
17493 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17495 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17496 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17497 isn't needed on 32-bit machines.
17499 * buffer.c (Fgenerate_new_buffer_name):
17500 Use EMACS_INT for count, not int.
17501 (advance_to_char_boundary): Return EMACS_INT, not int.
17503 * data.c (Qcompiled_function): Now static.
17505 * window.c (window_body_lines): Now static.
17507 * image.c (gif_load): Rename local to avoid shadowing.
17509 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17510 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17511 * alloc.c (make_save_value): Integer argument is now of type
17512 ptrdiff_t, not int.
17513 (mark_object): Use ptrdiff_t, not int.
17514 * lisp.h (pD): New macro.
17515 * print.c (print_object): Use it.
17517 * alloc.c: Use EMACS_INT, not int, to count objects.
17518 (total_conses, total_markers, total_symbols, total_vector_size)
17519 (total_free_conses, total_free_markers, total_free_symbols)
17520 (total_free_floats, total_floats, total_free_intervals)
17521 (total_intervals, total_strings, total_free_strings):
17522 Now EMACS_INT, not int. All uses changed.
17523 (Fgarbage_collect): Compute overall total using a double, so that
17524 integer overflow is less likely to be a problem. Check for overflow
17525 when converting back to an integer.
17526 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17527 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17528 These were 'int' variables that could overflow on 64-bit hosts;
17529 they were never used, so remove them instead of repairing them.
17530 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17531 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17532 Previously, this ceilinged at INT_MAX, but that doesn't work on
17534 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17536 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17537 (allocate_vectorlike): Check for ptrdiff_t overflow.
17538 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17539 when a (possibly-narrower) signed value would do just as well.
17540 We prefer using signed arithmetic, to avoid comparison confusion.
17542 * alloc.c: Catch some string size overflows that we were missing.
17543 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17544 for convenience in STRING_BYTES_MAX.
17545 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17546 The definition here is exact; the one in lisp.h was approximate.
17547 (allocate_string_data): Check for string overflow. This catches
17548 some instances we weren't catching before. Also, it catches
17549 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17550 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17551 and ptrdiff_t and EMACS_INT are both 64 bits.
17553 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17554 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17555 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17557 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17559 * alloc.c (Fmake_string): Check for out-of-range init.
17561 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17563 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17565 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17567 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17568 xg_get_default_scrollbar_width.
17570 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17571 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17572 (style_changed_cb): Call update_theme_scrollbar_width and call
17573 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17574 all frames (Bug#8505).
17575 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17576 Call gtk_window_set_resizable if HAVE_GTK3.
17577 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
17578 and height if HAVE_GTK3 (Bug#8505).
17579 (scroll_bar_width_for_theme): New variable.
17580 (update_theme_scrollbar_width): New function.
17581 (xg_get_default_scrollbar_width): Move code to
17582 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17583 (xg_initialize): Call update_theme_scrollbar_width.
17585 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17587 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17589 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17591 * frame.c (make_frame): Call other_buffer_safely instead of
17594 * window.c (temp_output_buffer_show): Call display_buffer with
17595 second argument Vtemp_buffer_show_specifiers and reset latter
17596 immediately after the call.
17597 (Vtemp_buffer_show_specifiers): New variable.
17598 (auto_window_vscroll_p, next_screen_context_lines)
17599 (Vscroll_preserve_screen_position): Remove leading asterisks from

17606 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
17607 (record_buffer): Remove unused local.
17608 * frame.c (other_visible_frames, frame_buffer_list): Now static.

17620 * widgetprv.h (emacsFrameClassRec): Remove decl.
17621 * window.c (delete_deletable_window): Now returns void, since it
17622 wasn't returning anything.
17623 (compare_window_configurations): Remove unused locals.
17624 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.

17644 * window.c (delete_deletable_window): Re-add.
17645 (Fset_window_configuration): Rewrite to handle dead buffers and
17646 consequently deletable windows.
17647 (window_tree, Fwindow_tree): Remove. Supply functionality in
17649 (compare_window_configurations): Simplify code.

17781 size_window, window_fixed_size_p, enlarge_window, delete_window.
17782 Remove static from declaration of Qdelete_window, it's
17783 temporarily needed by Fbury_buffer.
17784 (replace_window): Don't assign orig_top_line and
17786 (Fdelete_window, delete_window): Remove. Window deletion is

17788 (window_loop): Remove DELETE_OTHER_WINDOWS case.
17789 Replace Fdelete_window calls with calls to Qdelete_window.
17790 (Fdelete_other_windows): Remove. Deleting other windows is

18163 value of a `display' property is a "replacing spec".
18164 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18165 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

18195 * gnutls.c: Use Emacs's memory allocators.
18196 Without this change, the gnutls library would invoke malloc etc.
18197 directly, which causes problems on non-SYNC_INPUT hosts, and which
18198 runs afoul of improving memory_full behavior. (Bug#8761)
18199 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18200 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18201 xfree instead of the default malloc, realloc, free.
18202 (Fgnutls_boot): No need to check for memory allocation failure,
18203 since xmalloc does that for us.

18234 Check for integer overflow with large hash tables.
18235 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18236 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18237 (SXHASH_REDUCE): New macro.
18238 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18239 Use it instead of discarding useful hash info with large hash values.
18240 (sxhash_float): New function.
18241 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18242 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18243 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18244 Rewrite to use FIXNUM_BITS, as this simplifies things.
18245 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18246 Adjust signatures to match updated version of code.
18247 (consing_since_gc): Now EMACS_INT, since a single hash table can
18248 use more than INT_MAX bytes.
18250 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18252 Make it possible to build with GCC-4.6+ -O2 -flto.
18254 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18256 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18258 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18259 Call minibuffer-inactive-mode.
18261 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18263 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18264 Update dependencies.
18266 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18268 * data.c (init_data): Remove code for UTS, this system is not
18271 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18273 Don't force ./temacs to start in terminal mode.
18275 * frame.c (make_initial_frame): Initialize faces in all cases, not
18276 only when CANNOT_DUMP is defined.
18277 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18279 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18281 * dispnew.c (add_window_display_history): Use const for the string
18282 pointer. Remove declaration, not needed.
18284 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18286 Use 'inline', not 'INLINE'.
18287 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18288 * alloc.c, fontset.c (INLINE): Remove.
18289 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18290 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18291 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18292 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18293 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18295 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18297 Make it possible to run ./temacs.
18299 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18300 syms_of_callproc does the same thing. Remove test for
18301 "initialized", do it in the caller.
18302 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18304 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18306 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18307 (read_minibuf): Use get_minibuffer.
18308 (syms_of_minibuf): Use DEFSYM.
18309 (Qmetadata): New var.
18310 * data.c (Qbuffer): Don't make it static.
18311 (syms_of_data): Use DEFSYM.
18313 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18315 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18316 (CCL_CODE_MIN): New macro.
18318 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18320 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18322 * eval.c (Qdebug): Now static.
18323 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18324 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18325 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18327 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18329 * image.c: Various fixes to ImageMagick code comments.
18330 (Fimagemagick_types): Doc fix.
18332 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18334 Minor fixes prompted by GCC 4.6.0 warnings.
18336 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18338 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18339 (x_clipboard_manager_save_all): Move extern decl to ...
18340 * xterm.h: ... here, so that it can be checked for consistency.
18342 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18344 * xselect.c (x_clipboard_manager_save_frame)
18345 (x_clipboard_manager_save_all): New functions.
18346 (Fx_clipboard_manager_save): Lisp function deleted.
18348 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18349 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18351 * xterm.h: Update prototype.
18353 2011-05-28 William Xu <william.xwl@gmail.com>
18355 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18356 exiting (Bug#8239).
18358 2011-05-28 Jim Meyering <meyering@redhat.com>
18360 Avoid a sign-extension bug in crypto_hash_function.
18361 * fns.c (to_uchar): Define.
18362 (crypto_hash_function): Use it to convert some newly-signed
18363 variables to unsigned, to avoid sign-extension bugs. For example,
18364 without this change, (md5 "truc") would evaluate to
18365 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18366 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18367 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18369 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18371 Integer overflow fixes.
18373 * dbusbind.c: Serial number integer overflow fixes.
18374 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18375 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18376 to hold a serial number that is too large for a fixnum.
18377 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18378 Check for serial numbers out of range. Decode any serial number
18379 that was so large that it became a float. (Bug#8722)
18381 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18382 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18383 Use XFASTINT rather than XUINT when numbers are nonnegative.
18384 (xd_append_arg, Fdbus_method_return_internal):
18385 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18386 arguments, check that Lisp number is nonnegative, rather than
18387 silently wrapping negative numbers around. (Bug#8722)
18388 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18391 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18393 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18395 ccl: Add integer overflow checks.
18396 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18397 (IN_INT_RANGE): New macros.
18398 (ccl_driver): Use them to check for integer overflow when
18399 decoding a CCL program. Many of the new checks are whether XINT (x)
18400 fits in int; it doesn't always, on 64-bit hosts. The new version
18401 doesn't catch all possible integer overflows, but it's an
18402 improvement. (Bug#8719)
18404 * alloc.c (make_event_array): Use XINT, not XUINT.
18405 There's no need for unsigned here.
18407 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18408 This follows up to the 2011-05-06 change that substituted uintptr_t
18409 for EMACS_INT. This case wasn't caught back then.
18411 Rework Fformat to avoid integer overflow issues.
18412 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18413 now (part of C89). Include <verify.h>.
18414 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18415 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18416 (Fformat): Avoid the prepass trying to compute sizes; it was only
18417 approximate and thus did not catch overflow reliably. Instead, walk
18418 through the format just once, formatting and computing sizes as we go,
18419 checking for integer overflow at every step, and allocating a larger
18420 buffer as needed. Keep track separately whether the format is
18421 multibyte. Keep only the most-recently calculated precision, rather
18422 than them all. Record whether each argument has been converted to
18423 string. Use EMACS_INT, not int, for byte and char and arg counts.
18424 Support field widths and precisions larger than INT_MAX. Avoid
18425 sprintf's undefined behavior with conversion specifications such as %#d
18426 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18427 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18428 formatting out-of-range floating point numbers with int
18429 formats. (Bug#8668)
18431 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18433 * data.c: Avoid integer truncation in expressions involving floats.
18434 * data.c: Include <intprops.h>.
18435 (arith_driver): When there's an integer overflow in an expression
18436 involving floating point, convert the integers to floating point
18437 so that the resulting value does not suffer from catastrophic
18438 integer truncation. For example, on a 64-bit host (* 4
18439 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18440 Do not rely on undefined behavior after integer overflow.
18442 merge count_size_as_multibyte, parse_str_to_multibyte
18443 * character.c, character.h (count_size_as_multibyte):
18444 Rename from parse_str_to_multibyte; all uses changed.
18445 Check for integer overflow.
18446 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18447 since it's now a duplicate of the other. This is more of
18448 a character than a buffer op, so better that it's in character.c.
18449 * fns.c, print.c: Adjust to above changes.
18451 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18453 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18455 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18457 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18458 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18459 (x_clipboard_manager_save): Now static.
18460 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18462 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18463 (crypto_hash_function): Now static.
18464 Fix pointer signedness problems. Avoid unnecessary initializations.
18466 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18468 * termhooks.h (Vselection_alist): Make it terminal-local.
18470 * terminal.c (create_terminal): Initialize it.
18472 * xselect.c: Support for clipboard managers.
18473 (Vselection_alist): Move to termhooks.h as terminal-local var.
18474 (LOCAL_SELECTION): New macro.
18475 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18476 (symbol_to_x_atom): Remove gratuitous arg.
18477 (x_handle_selection_request, lisp_data_to_selection_data)
18478 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18479 (x_own_selection, x_get_local_selection, x_convert_selection):
18480 New arg, specifying work frame. Use terminal-local Vselection_alist.
18481 (some_frame_on_display): Delete unused function.
18482 (Fx_own_selection_internal, Fx_get_selection_internal)
18483 (Fx_disown_selection_internal, Fx_selection_owner_p)
18484 (Fx_selection_exists_p): New optional frame arg.
18485 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18486 (x_handle_selection_clear): Don't treat other terminals with the
18487 same keyboard specially. Use the terminal-local Vselection_alist.
18488 (x_clear_frame_selections): Use Frun_hook_with_args.
18490 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18492 * xterm.h: Add support for those atoms.
18494 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18496 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18497 (converted_selections, conversion_fail_tag): New global variables.
18498 (x_selection_request_lisp_error): Free the above.
18499 (x_get_local_selection): Remove unnecessary code.
18500 (x_reply_selection_request): Args changed; handle arbitrary array
18501 of converted selections stored in converted_selections.
18502 Separate the XChangeProperty and SelectionNotify steps.
18503 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18504 (x_convert_selection): New function.
18505 (x_handle_selection_event): Simplify.
18506 (x_get_foreign_selection): Don't ignore incoming requests while
18507 waiting for an answer; this will fail when we implement
18508 SAVE_TARGETS, and seems unnecessary anyway.
18509 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18510 (Vx_sent_selection_functions): Doc fix.
18512 2011-05-26 Leo Liu <sdl.web@gmail.com>
18514 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18516 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18518 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18520 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18521 for fringe update if it has periodic bitmap.
18522 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18523 and fringe_bitmap_periodic_p.
18525 * fringe.c (get_fringe_bitmap_data): New function.
18526 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18527 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18528 row. Mark glyph row for fringe update if periodicity changed.
18530 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18531 for fringe update unless it has periodic bitmap.
18533 2011-05-25 Kenichi Handa <handa@m17n.org>
18535 * xdisp.c (get_next_display_element): Set correct it->face_id for
18536 a static composition.
18538 2011-05-24 Leo Liu <sdl.web@gmail.com>
18541 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18543 * fns.c (crypto_hash_function, Fsha1): New function.
18544 (Fmd5): Use crypto_hash_function.
18545 (syms_of_fns): Add Ssha1.
18547 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18549 * gnutls.c: Remove unused macros.
18550 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18551 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18552 Remove macros that are defined and never used.
18553 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18555 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18557 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18558 (Fx_get_selection_internal): Minor cleanup.
18559 (Fx_own_selection_internal): Rename arguments for consistency with
18562 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18564 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18566 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18568 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18570 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18572 * dispnew.c (scrolling_window): Don't exclude the case that the
18573 last enabled row in the desired matrix touches the bottom boundary.
18575 2011-05-21 Glenn Morris <rgm@gnu.org>
18577 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18578 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18579 and add some more files.
18581 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18583 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18584 report_file_error introduced by the change from 2011-05-07.
18586 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18588 * systime.h (Time): Define only if emacs is defined.
18589 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18590 where the include path doesn't have X11/X.h by default. See
18591 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18593 2011-05-20 Kenichi Handa <handa@m17n.org>
18595 * composite.c (find_automatic_composition): Fix previous change.
18597 2011-05-20 Glenn Morris <rgm@gnu.org>
18599 * lisp.mk: New file, split from Makefile.in.
18600 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18601 (shortlisp): Remove.
18602 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18604 2011-05-19 Glenn Morris <rgm@gnu.org>
18606 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18607 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18608 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18609 (lisp): Set the order to that of loadup.el.
18610 (shortlisp): Make it a copy of $lisp.
18611 (SOME_MACHINE_LISP): Remove.
18612 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18613 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18615 2011-05-18 Kenichi Handa <handa@m17n.org>
18617 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18618 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18619 (find_automatic_composition): Mostly rewrite for efficiency.
18621 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18623 * makefile.w32-in: Update dependencies.
18625 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18627 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18628 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18630 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18632 Fix some integer overflow issues, such as string length overflow.
18634 * insdel.c (count_size_as_multibyte): Check for string overflow.
18636 * character.c (lisp_string_width): Check for string overflow.
18637 Use EMACS_INT, not int, for string indexes and lengths; in
18638 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18639 the resulting string length overflows an EMACS_INT; instead,
18640 report a string overflow if no precision given. When checking for
18641 precision exhaustion, use a check that cannot possibly have
18642 integer overflow. (Bug#8675)
18643 * character.h (lisp_string_width): Adjust to new signature.
18645 * alloc.c (string_overflow): New function.
18646 (Fmake_string): Use it. This doesn't change behavior, but saves
18647 a few bytes and will simplify future changes.
18648 * character.c (string_escape_byte8): Likewise.
18649 * lisp.h (string_overflow): New decl.
18651 Fixups, following up to the user-interface timestamp change.
18652 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18653 for UI timestamps, instead of unsigned long.
18654 * msdos.c (mouse_get_pos): Likewise.
18655 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18656 * w32gui.h (Time): Define by including "systime.h" rather than by
18657 declaring it ourselves. (Bug#8664)
18659 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18660 * image.c (clear_image_cache): Likewise.
18662 * term.c (term_mouse_position): Don't assume time_t wraparound.
18664 Be more systematic about user-interface timestamps.
18665 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18666 and sometimes 'EMACS_UINT', to represent these timestamps.
18667 This change causes it to use 'Time' uniformly, as that's what X uses.
18668 This makes the code easier to follow, and makes it easier to catch
18669 integer overflow bugs such as Bug#8664.
18670 * frame.c (Fmouse_position, Fmouse_pixel_position):
18671 Use Time, not unsigned long, for user-interface timestamps.
18672 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18673 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18674 * keyboard.h (last_event_timestamp): Likewise.
18675 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18676 * menu.h (xmenu_show): Likewise.
18677 * term.c (term_mouse_position): Likewise.
18678 * termhooks.h (struct input_event.timestamp): Likewise.
18679 (struct terminal.mouse_position_hook): Likewise.
18680 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18681 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18682 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18683 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18684 what it was before.
18685 * menu.h, termhooks.h: Include "systime.h", for Time.
18687 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18688 Don't assume that the difference between two unsigned long values
18689 can fit into an integer. At this point, we know button_down_time
18690 <= event->timestamp, so the difference must be nonnegative, so
18691 there's no need to cast the result if double-click-time is
18692 nonnegative, as it should be; check that it's nonnegative, just in
18693 case. This bug is triggered when events are more than 2**31 ms
18694 apart (about 25 days). (Bug#8664)
18696 * xselect.c (last_event_timestamp): Remove duplicate decl.
18697 (x_own_selection): Remove needless cast to unsigned long.
18699 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18700 that always fit in int. Use a sentinel instead of a counter, to
18701 avoid a temp and to allay GCC's concerns about possible int overflow.
18702 * frame.h (struct frame): Use int for menu_bar_items_used
18703 instead of EMACS_INT, since it always fits in int.
18705 * menu.c (grow_menu_items): Check for int overflow.
18707 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18709 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18710 Before, the code was not consistent. These values cannot exceed
18711 2**31 - 1 so there's no need to make them unsigned.
18712 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18713 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18714 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18716 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18718 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18719 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18720 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18721 presumably because the widths might not match.
18723 * window.c (size_window): Avoid needless test at loop start.
18725 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18727 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18729 2011-05-12 Drew Adams <drew.adams@oracle.com>
18731 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18733 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18735 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18736 `width' to `bar_area_x' and `bar_area_width', respectively.
18737 (x_scroll_run): Take account of fringe background extension.
18739 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18740 Rename local vars `left' and `width' to `bar_area_x' and
18741 `bar_area_width', respectively.
18742 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18743 background extension.
18745 2011-05-10 Jim Meyering <meyering@redhat.com>
18747 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18749 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18751 * image.c (Finit_image_library): Return t for built-in image types,
18752 like pbm and xbm. (Bug#8640)
18754 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18756 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18758 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18760 * w32console.c (Fset_screen_color): Doc fix.
18761 (Fget_screen_color): New function.
18762 (syms_of_ntterm): Defsubr it.
18764 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18765 unlink the temporary file if Fcall_process didn't create it in the
18767 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18768 child process will be redirected to a file specified with `:file'.
18769 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18770 cue to call_process_cleanup not to close that handle.
18772 2011-05-07 Ben Key <bkey76@gmail.com>
18774 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18775 one of two shell specific rules, either bootstrap-temacs-CMD or
18776 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18777 to the previous implementation of the bootstrap-temacs rule.
18778 The bootstrap-temacs-CMD rule is similar to the previous
18779 implementation of the bootstrap-temacs rule except that it
18780 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18783 These changes, along with some changes to nt/configure.bat,
18784 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18785 earlier fix to add support for --cflags and --ldflags options
18786 that include quotes so that it works whether make uses cmd or
18789 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18791 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18792 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18794 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18795 a string. Handle both cases.
18796 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18797 (Fdbus_register_method): Use Qinvalid_function.
18799 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18801 * makefile.w32-in: Update dependencies.
18802 (LISP_H): Add inttypes.h and stdin.h.
18803 (PROCESS_H): Add unistd.h.
18805 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18807 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18808 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18810 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18812 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18814 * term.c (vfatal): Remove stray call to va_end.
18815 It's not needed and the C Standard doesn't allow it here anyway.
18817 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18818 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18820 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18823 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18825 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18827 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18829 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18831 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18833 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18834 * charset.c (Fdefine_charset_internal): Don't initialize
18835 charset.code_space[15]. The value was garbage, on hosts with
18836 32-bit int (Bug#8600).
18838 * lread.c (read_integer): Be more consistent with string-to-number.
18839 Use string_to_number to do the actual conversion; this avoids
18840 rounding errors and fixes some other screwups. Without this fix,
18841 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18842 (digit_to_number): Move earlier, for benefit of read_integer.
18843 Return -1 if the digit is out of range for the base, -2 if it is
18844 not a digit in any supported base. (Bug#8602)
18846 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18848 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18849 to match comment at start of function. This also removes a
18850 GCC warning about overflow in a 32+64-bit port.
18852 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18854 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18855 Reported by Stefan Monnier in
18856 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18857 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18858 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18860 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18861 (EMACS_UINTPTR): Likewise, with uintptr_t.
18863 * lisp.h: Prefer 64-bit EMACS_INT if available.
18864 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18865 on 32-bit hosts that have 64-bit int, so that they can access
18867 However, temporarily disable this change unless the temporary
18868 symbol WIDE_EMACS_INT is defined.
18870 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18872 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18873 This removes an assumption that EMACS_INT and long are the same
18874 width as pointers. The assumption is true for Emacs porting targets
18875 now, but we want to make other targets possible.
18876 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18877 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18878 In the rest of the code, change types of integers that hold casted
18879 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18880 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18881 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18882 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18883 No need to cast type when ORing.
18884 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18885 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18886 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18887 assume EMACS_INT is the same width as char *.
18888 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18889 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18890 Remove no-longer-needed casts.
18891 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18892 (xg_tool_bar_help_callback, xg_make_tool_item):
18893 Use EMACS_INTPTR to hold an integer
18894 that will be cast to void *; this can avoid a GCC warning
18895 if EMACS_INT is not the same width as void *.
18896 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18897 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18898 (current_message_1, set_message_1):
18899 Use a local to convert to proper width without a cast.
18900 * xmenu.c (dialog_selection_callback): Likewise.
18902 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18903 Also, don't assume VALBITS / RAND_BITS is less than 5,
18904 and don't rely on undefined behavior when shifting a 1 left into
18906 * lisp.h (get_random): Change signature to match.
18908 * lread.c (hash_string): Use size_t, not int, for hash computation.
18909 Normally we prefer signed values; but hashing is special, because
18910 it's better to use unsigned division on hash table sizes so that
18911 the remainder is nonnegative. Also, size_t is the natural width
18912 for hashing into memory. The previous code used 'int', which doesn't
18913 retain enough info to hash well into very large tables.
18914 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18916 * dbusbind.c: Don't possibly lose pointer info when converting.
18917 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18918 Use XPNTR rather than XHASH, so that the high-order bits of
18919 the pointer aren't lost when converting through void *.
18921 * eval.c (Fautoload): Don't double-shift a pointer.
18923 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18925 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18927 * gnutls.c (DEF_GNUTLS_FN):
18928 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18930 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18932 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18935 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18937 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18938 New version that can reserve upto 2GB of heap space.
18940 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18942 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18944 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18946 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18947 `gnutls_certificate_set_x509_key_file'.
18949 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18951 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18952 Update dependencies.
18954 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18956 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18957 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18958 Remove unused parameter `fildes'.
18959 * process.c (read_process_output, send_process): Don't pass it.
18961 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18963 Fix previous change: the library cache is defined in w32.c.
18964 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18965 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18967 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18969 Implement dynamic loading of GnuTLS on Windows.
18971 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18972 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18973 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18976 * gnutls.c (Qgnutls_dll): Define.
18977 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18978 (gnutls_*): Declare function pointers.
18979 (init_gnutls_functions): New function to initialize function pointers.
18980 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
18981 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
18982 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18983 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18984 (emacs_gnutls_write, emacs_gnutls_read)
18985 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18986 (Fgnutls_available_p): New function.
18987 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
18988 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
18989 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18991 * image.c: Include w32.h.
18992 (Vimage_type_cache): Delete.
18993 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
18994 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18995 (w32_delayed_load): Move to w32.c.
18997 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18999 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19000 (w32_delayed_load): Move from image.c. When loading a library, record
19001 its filename in the :loaded-from property of the library id.
19002 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19003 Initialize and staticpro them.
19004 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19006 * process.c: Include lisp.h before w32.h, not after.
19007 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19008 instead of gnutls_record_check_pending.
19010 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19012 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19014 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19015 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19018 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19020 * xterm.c (x_set_frame_alpha): Do not set property on anything
19021 else than FRAME_X_OUTER_WINDOW (Bug#8608).
19023 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19025 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19027 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19029 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
19030 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

19036 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
19037 (Qgnutls_bootprop_callbacks_verify): Make static.
19039 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
19041 * callproc.c: Indentation fixup.
19043 * sysdep.c (wait_for_termination_1): Make static.
19044 (wait_for_termination, interruptible_wait_for_termination):
19045 Move after wait_for_termination_1.
19047 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
19049 * sysdep.c (interruptible_wait_for_termination): New function
19050 which is like wait_for_termination, but allows keyboard
19053 * callproc.c (Fcall_process): Add (:file "file") as an option for
19055 (Fcall_process_region): Ditto.
19057 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19059 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19060 rather than `XVECTOR (FOO)->size'.
19062 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19063 inttypes.h, as a gnulib replacement is used if it not available in
19066 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19068 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19069 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19070 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19072 * coding.c (coding_alloc_by_realloc): Error out if destination
19073 will grow beyond MOST_POSITIVE_FIXNUM.
19074 (decode_coding_emacs_mule): Abort if there isn't enough place in
19075 charbuf for the composition carryover bytes. Reserve an extra
19076 space for up to 2 characters produced in a loop.
19077 (decode_coding_iso_2022): Abort if there isn't enough place in
19078 charbuf for the composition carryover bytes.
19080 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19082 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19083 aborting when %lld or %lll format is passed.
19084 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19085 %llo or %llx format is passed. (Bug#8545)
19087 * window.c (window_scroll_line_based): Use a marker instead of
19088 simple variables to record original value of point. (Bug#7952)
19090 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19091 produced by %s or %c overflows available buffer space. (Bug#8545)
19093 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19095 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19096 (SIZE_MAX): Move defn after all includes, as they might #define it.
19098 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19100 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19102 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19104 * keyboard.c (Qdelayed_warnings_hook): Define.
19105 (command_loop_1): Run `delayed-warnings-hook'
19106 if Vdelayed_warnings_list is non-nil.
19107 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19108 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19110 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19112 * doprnt.c (doprnt): Don't return value smaller than the buffer
19113 size if the message was truncated. (Bug#8545).
19115 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19117 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19118 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19120 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19122 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19124 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19126 * makefile.w32-in: Update dependencies.
19128 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19130 Improve `doprnt' and its usage. (Bug#8545)
19131 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19132 `format_end'. Remove support for %l as a conversion specifier.
19133 Don't use xrealloc. Improve diagnostics when the %l size modifier
19134 is used. Update the commentary.
19136 * eval.c (verror): Simplify calculation of size_t.
19138 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19141 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19143 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19146 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19148 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19149 This makes this file independent of the recent pseudovector change.
19151 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19153 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19155 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19156 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19157 Remove unused local.
19158 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19160 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19161 GCC 4.6.0 optimizes based on type-based alias analysis.
19162 For example, if b is of type struct buffer * and v of type struct
19163 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19164 != &v->size, and therefore "v->size = 1; b->size = 2; return
19165 v->size;" must therefore return 1. This assumption is incorrect
19166 for Emacs, since it type-puns struct Lisp_Vector * with many other
19167 types. To fix this problem, this patch adds a new type struct
19168 vectorlike_header that documents the constraints on layout of vectors
19169 and pseudovectors, and helps optimizing compilers not get fooled
19170 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19171 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19172 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19174 (XSETPVECTYPE): Rewrite in terms of new macro.
19175 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19176 This is a bit clearer, and further avoids the possibility of
19177 undesirable aliasing.
19178 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19179 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19180 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19181 since Lisp_Subr is a special case (no "next" field).
19182 (ASIZE): Now uses header.size rather than size.
19183 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19184 to avoid the hassle of writing XVECTOR (foo)->header.size.
19185 (struct vectorlike_header): New type.
19186 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19187 object, to help avoid aliasing.
19188 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19189 (SUBRP): Likewise, since Lisp_Subr is a special case.
19190 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19191 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19192 (struct Lisp_Hash_Table): Combine first two members into a single
19193 struct vectorlike_header member. All uses of "size" and "next" members
19194 changed to be "header.size" and "header.next".
19195 * buffer.h (struct buffer): Likewise.
19196 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19197 * frame.h (struct frame): Likewise.
19198 * process.h (struct Lisp_Process): Likewise.
19199 * termhooks.h (struct terminal): Likewise.
19200 * window.c (struct save_window_data, struct saved_window): Likewise.
19201 * window.h (struct window): Likewise.
19202 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19203 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19204 * buffer.c (init_buffer_once): Likewise.
19205 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19207 * process.c (Fformat_network_address): Use local var for size,
19210 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19212 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19213 * data.c (atof): Remove decl; no longer used or needed.
19214 (digit_to_number): Move to lread.c.
19215 (Fstring_to_number): Use new string_to_number function, to be
19216 consistent with how the Lisp reader treats infinities and NaNs.
19217 Do not assume that floating-point numbers represent EMACS_INT
19218 without losing information; this is not true on most 64-bit hosts.
19219 Avoid double-rounding errors, by insisting on integers when
19220 parsing non-base-10 numbers, as the documentation specifies.
19221 * lisp.h (string_to_number): New decl, replacing ...
19222 (isfloat_string): Remove.
19223 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19224 (read1): Do not accept +. and -. as integers; this
19225 appears to have been a coding error. Similarly, do not accept
19226 strings like +-1e0 as floating point numbers. Do not report
19227 overflow for integer overflows unless the base is not 10 which
19228 means we have no simple and reliable way to continue.
19229 Break out the floating-point parsing into a new
19230 function string_to_number, so that Fstring_to_number parses
19231 floating point numbers consistently with the Lisp reader.
19232 (digit_to_number): Move here from data.c. Make it static inline.
19233 (E_CHAR, EXP_INT): Remove, replacing with ...
19234 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19235 (string_to_number): New function, replacing isfloat_string.
19236 This function checks for valid syntax and produces the resulting
19237 Lisp float number too. Rework it so that string-to-number
19238 no longer mishandles examples like "1.0e+". Use strtoumax,
19239 so that overflow for non-base-10 numbers is reported only when
19240 there's no portable and simple way to convert to floating point.
19242 * textprop.c (set_text_properties_1): Rewrite for clarity,
19243 and to avoid GCC warning about integer overflow.
19245 * intervals.h (struct interval): Use EMACS_INT for members
19246 where EMACS_UINT might cause problems. See
19247 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19248 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19249 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19251 (offset_intervals): Tell GCC not to worry about length overflow
19252 when negating a negative length.
19254 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19255 (overrun_check_free): Likewise.
19257 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19258 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19261 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19262 (gnutls_make_error): Rename local to avoid shadowing.
19263 (gnutls_emacs_global_deinit): ifdef out; not used.
19264 (Fgnutls_boot): Use const for pointer to readonly storage.
19265 Comment out unused local. Fix pointer signedness problems.
19267 * lread.c (openp): Don't stuff size_t into an 'int'.
19268 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19269 about possible signed overflow.
19271 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19272 (GDK_KEY_g): Don't define if already defined.
19273 (xg_prepare_tooltip): Avoid pointer signedness problem.
19274 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19276 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19277 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19279 * xfns.c (Fx_window_property): Simplify a bit,
19280 to make a bit faster and to avoid GCC 4.6.0 warning.
19281 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19283 * fns.c (internal_equal): Don't assume size_t fits in int.
19285 * alloc.c (compact_small_strings): Tighten assertion a little.
19287 Replace pEd with more-general pI, and fix some printf arg casts.
19288 * lisp.h (pI): New macro, generalizing old pEd macro to other
19289 conversion specifiers. For example, use "...%"pI"d..." rather
19290 than "...%"pEd"...".
19291 (pEd): Remove. All uses replaced with similar uses of pI.
19292 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19293 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19294 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19295 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19296 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19297 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19298 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19300 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19301 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19302 * print.c (safe_debug_print, print_object): Likewise.
19303 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19305 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19306 avoiding the 0 flag, which is not portable.
19307 * process.c (Fmake_network_process): Use pI to avoid cast.
19308 * region-cache.c (pp_cache): Likewise.
19309 * xdisp.c (decode_mode_spec): Likewise.
19310 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19311 behavior on 64-bit hosts with printf arg.
19312 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19313 (x_stop_queuing_selection_requests): Likewise.
19314 (x_get_window_property): Don't truncate byte count to an 'int'
19317 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19318 here, since it parses constructs like leading '-' and spaces,
19319 which are not wanted; and it overflows with large numbers.
19320 Instead, simply match F[0-9]+, which is what is wanted anyway.
19322 * alloc.c: Remove unportable assumptions about struct layout.
19323 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19324 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19325 (allocate_vectorlike, make_pure_vector): Use the new macros,
19326 plus offsetof, to remove unportable assumptions about struct layout.
19327 These assumptions hold on all porting targets that I know of, but
19328 they are not guaranteed, they're easy to remove, and removing them
19329 makes further changes easier.
19331 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19332 This doesn't fix a bug but makes the code clearer.
19333 (string_overrun_cookie): Now const. Use initializers that
19334 don't formally overflow signed char, to avoid warnings.
19335 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19336 can cause Emacs to crash when string overrun checking is enabled.
19337 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19338 multiple of sizeof (EMACS_INT); it need not be, if
19339 alignof(EMACS_INT) < sizeof (EMACS_INT).
19340 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19342 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19346 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
19348 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
19349 supposed to be handshaking. (Bug#8556)
19350 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19352 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
19354 * lisp.h (Qdebug): List symbol.
19355 * eval.c (Qdebug): Restore global linkage.
19356 * keyboard.c (debug-on-event): New variable.
19357 (handle_user_signal): Break into debugger when debug-on-event
19358 matches the current signal symbol.
19360 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19362 * alloc.c (check_sblock, check_string_bytes)
19363 (check_string_free_list): Convert to standard C.
19365 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19367 * w32.c (emacs_gnutls_push): Fix typo.
19369 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19371 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19372 "cast to pointer from integer of different size".
19374 Improve doprnt and its use in verror. (Bug#8545)
19375 * doprnt.c (doprnt): Document the set of format control sequences
19376 supported by the function. Use SAFE_ALLOCA instead of always
19379 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19380 is one byte too soon. Don't use xrealloc; instead xfree and
19383 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19385 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19388 * gnutls.c: Renamed global_initialized to
19389 gnutls_global_initialized. Added internals for the
19390 :verify-hostname-error, :verify-error, and :verify-flags
19391 parameters of `gnutls-boot' and documented those parameters in the
19392 docstring. Start callback support.
19393 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19394 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19395 on error. Return error code.
19396 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19397 (emacs_gnutls_read): Likewise.
19398 (Fgnutls_boot): Return handshake error code.
19399 (emacs_gnutls_handle_error): New function.
19400 (wsaerror_to_errno): Likewise.

19455 changes in globals.h immediately force recompilation.
19456 (TAGS): Depend on $(CURDIR)/m/intel386.h and
19457 $(CURDIR)/s/ms-w32.h.
19458 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

19462 <char-direction-table>: Deleted.
19464 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19466 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19467 * doprnt.c: Include limits.h.
19468 (SIZE_MAX): New macro.
19469 (doprnt): Return a size_t value. 2nd arg is now size_t.
19470 Many local variables are now size_t instead of int or unsigned.
19471 Improve overflow protection. Support `l' modifier for integer
19472 conversions. Support %l conversion. Don't assume an EMACS_INT
19473 argument for integer conversions and for %c.
19475 * lisp.h (doprnt): Restore prototype.
19477 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19478 $(SRC)/character.h.
19480 * Makefile.in (base_obj): Add back doprnt.o.
19482 * deps.mk (doprnt.o): Add back prerequisites.
19483 (callint.o): Depend on character.h.
19485 * eval.c (internal_lisp_condition_case): Include the handler
19486 representation in the error message.
19487 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19488 when breaking from the loop.
19490 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19492 * callint.c (Fcall_interactively): When displaying error message
19493 about invalid control letter, pass the character's codepoint, not
19494 a pointer to its multibyte form. Improve display of the character
19495 in octal and display also its hex code.
19497 * character.c (char_string): Use %x to display the (unsigned)
19498 codepoint of an invalid character, to avoid displaying a bogus
19501 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19502 `error', not SYMBOL_NAME itself.
19504 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19505 character arguments to `error'.
19507 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19508 to `error' in error message about FINAL_CHAR argument. Make sure
19509 FINAL_CHAR is a character, and use %c when it is passed as
19510 argument to `error'.
19512 2011-04-23 Eli Zaretskii <eliz@gnu.org>

19699 * nsfont.m: Fixed bugs in ns_get_family and
19700 ns_descriptor_to_entity that were caused by using free to
19701 deallocate memory blocks that were allocated by xmalloc (via
19702 xstrdup). This caused Emacs to crash when compiled with
19703 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
19704 --enable-checking=xmallocoverrun). xfree is now used to
19705 deallocate these memory blocks.

19721 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
19722 (emacs_read, emacs_write): Use it.
19723 * process.c (send_process): Adjust to the new signatures of
19724 emacs_write and emacs_gnutls_write. Do not attempt to store

20053 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
20054 * lisp.h: Remove these decls.
20056 * buffer.c (buffer_count): Remove unused var.
20058 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
20059 so that it's not optimized away.
20060 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
20061 * dispextern.h (bidi_dump_cached_states): Remove, since it's
20062 exported only to the debugger.
20064 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
20065 * atimer.h (run_all_atimers): Remove; not exported.
20067 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20068 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20069 was inaccessible from Lisp.
20070 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20071 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20073 alloc.c: Import and export fewer symbols, and remove unused items.
20074 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20076 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20077 it's not optimized away by whole-program optimization.
20078 (message_enable_multibyte, free_misc): Remove.
20079 (catchlist, handlerlist, mark_backtrace):
20080 Declare only if BYTE_MARK_STACK.

20089 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
20090 (mark_backtrace): Define only if BYTE_MARK_STACK.
20091 * xdisp.c (message_enable_multibyte): Now static.
20093 Declare Lisp_Object Q* variables to be 'static' if not exported.
20094 This makes it easier for human readers (and static analyzers)
20095 to see whether these variables are used from other modules.
20096 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
20097 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
20098 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

20106 Remove decls of unexported vars.
20107 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20109 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20111 Make Emacs functions such as Fatom 'static' by default.
20112 This makes it easier for human readers (and static analyzers)
20113 to see whether these functions can be called from other modules.
20114 DEFUN now defines a static function. To make the function external
20115 so that it can be used in other C modules, use the new macro DEFUE.
20116 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20117 (Finit_image_library):
20118 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
20119 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
20120 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
20121 Remove decls, since these functions are now static.
20122 (Funintern, Fget_internal_run_time): New decls, since these functions
20123 were already external.
20125 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
20126 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

20132 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
20133 Mark functions with DEFUE instead of DEFUN,
20134 if they are used in other modules.
20135 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20136 decls for now-static functions.
20137 * buffer.h (Fdelete_overlay): Remove decl.

20147 * image.c (Finit_image_library): New forward static decl.
20148 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
20149 * intervals.h (Fprevious_property_change):
20150 (Fremove_list_of_text_properties): Remove decls.
20151 * keyboard.c (Fthis_command_keys): Remove decl.
20152 (Fcommand_execute): New forward static decl.

20168 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
20170 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
20173 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20175 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20176 when at ZV. (Bug#8487)
20178 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20180 * charset.c (Fclear_charset_maps): Use xfree instead of free.

20183 * sound.c (sound_cleanup, alsa_close): Likewise.
20184 * termcap.c (tgetent): Likewise.
20185 * xfns.c (x_default_font_parameter): Likewise.
20186 * xsettings.c (read_and_apply_settings): Likewise.
20188 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20189 (overrun_check_free): Protoize.
20191 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20193 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20194 since callers should never pass a negative size.
20195 Change the signature to match that of plain 'read' and 'write'; see
20196 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20197 * lisp.h: Update prototypes of emacs_write and emacs_read.
20199 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20201 * xdisp.c (redisplay_window): Don't try to determine the character
20202 position of the scroll margin if the window start point w->startp
20203 is outside the buffer's accessible region. (Bug#8468)
20205 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20207 Fix write-region and its subroutines for buffers > 2GB.
20208 * fileio.c (a_write, e_write): Modify declaration of arguments and
20209 local variables to support buffers larger than 2GB.
20210 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20212 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20213 argument, local variables, and return value.
20215 * lisp.h: Update prototypes of emacs_write and emacs_read.
20217 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20219 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20221 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20223 Fix more problems found by GCC 4.6.0's static checks.
20225 * xdisp.c (vmessage): Use a better test for character truncation.
20227 * charset.c (load_charset_map): <, not <=, for optimization,
20228 and to avoid potential problems with integer overflow.
20229 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20230 * casetab.c (set_identity, shuffle): Likewise.
20231 * editfns.c (Fformat): Likewise.
20232 * syntax.c (skip_chars): Likewise.
20234 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20235 This also lets GCC 4.6.0 generate slightly better loop code.
20237 * callint.c (Fcall_interactively): <, not <=, for optimization.
20238 (Fcall_interactively): Count the number of arguments produced,
20239 not the number of arguments given. This is simpler and lets GCC
20240 4.6.0 generate slightly better code.
20242 * ftfont.c: Distingish more carefully between FcChar8 and char.
20243 The previous code passed unsigned char * to a functions like
20244 strlen and xstrcasecmp that expect char *, which does not
20245 conform to the C standard.
20246 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20247 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20248 char * when the C standard requires it.
20250 * keyboard.c (read_char): Remove unused var.
20252 * eval.c: Port to Windows vsnprintf (Bug#8435).
20253 Include <limits.h>.
20254 (SIZE_MAX): Define if the headers do not.
20255 (verror): Do not give up if vsnprintf returns a negative count.
20256 Instead, grow the buffer. This ports to Windows vsnprintf, which
20257 does not conform to C99. Problem reported by Eli Zaretskii.
20258 Also, simplify the allocation scheme, by avoiding the need for
20259 calling realloc, and removing the ALLOCATED variable.
20261 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20263 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20264 But keep the doprint source code for now, as we might revamp it
20265 and use it again (Bug#8435).
20266 * lisp.h (doprnt): Remove.
20267 * Makefile.in (base_obj): Remove doprnt.o.
20268 * deps.mk (doprnt.o): Remove.
20270 error: Print 32- and 64-bit integers portably (Bug#8435).
20271 Without this change, on typical 64-bit hosts error ("...%d...", N)
20272 was used to print both 32- and 64-bit integers N, which relied on
20273 undefined behavior.
20274 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20275 * lisp.h (error, verror): Mark as printf-like functions.
20276 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20277 Report overflow in size calculations when allocating printf buffer.
20278 Do not truncate output string at its first null byte.
20279 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20280 Truncate the output at a character boundary, since vsnprintf does not
20282 * charset.c (check_iso_charset_parameter): Convert internal
20283 character to string before calling 'error', since %c now has the
20285 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20286 overflow when computing char to be passed to 'error'. Do not
20287 pass Lisp_Object to 'error'; pass the integer instead.
20288 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20289 formatted with plain %d.
20291 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20293 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20295 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20297 * xterm.c (x_catch_errors): Remove duplicate declaration.
20299 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20301 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20303 2011-04-10 Jim Meyering <meyering@redhat.com>
20305 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20306 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20307 return ssize_t not "int", and use size_t as the buffer length.
20308 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20309 * gnutls.h: Update declarations.
20310 * process.c (read_process_output): Use ssize_t, to match.
20311 (send_process): Likewise.
20313 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20315 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20317 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20319 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20320 Use unsigned char, to match FcChar8 type definition.
20322 * xterm.c (handle_one_xevent):
20323 * xmenu.c (create_and_show_popup_menu):
20324 * xselect.c (x_decline_selection_request)
20325 (x_reply_selection_request): Avoid type-punned deref of X events.
20327 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20329 Fix some uses of `int' instead of EMACS_INT.
20330 * search.c (string_match_1, fast_string_match)
20331 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20332 (scan_buffer, find_next_newline_no_quit)
20333 (find_before_next_newline, search_command, Freplace_match)
20334 (Fmatch_data): Make some `int' variables be EMACS_INT.
20336 * xdisp.c (display_count_lines): 3rd argument and return value now
20337 EMACS_INT. All callers changed.
20338 (pint2hrstr): Last argument is now EMACS_INT.
20340 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20341 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20342 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

20353 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20354 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20356 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20357 (encode_invocation_designation): Last argument P_NCHARS is now
20359 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20360 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20362 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20365 * ccl.c (Fccl_execute_on_string): Declare some variables
20368 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20370 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20372 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20374 * process.c (Fformat_network_address): Doc fix.
20376 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20378 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20380 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20382 * keyboard.c (read_char): Call Lisp function help-form-show,
20383 instead of using internal_with_output_to_temp_buffer.
20384 (Qhelp_form_show): New var.
20385 (syms_of_keyboard): Use DEFSYM macro.
20387 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20391 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
20393 * process.c (Flist_processes): Remove to Lisp.
20394 (list_processes_1): Delete.
20396 2011-04-06 Eli Zaretskii <eliz@gnu.org>
20398 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20400 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20402 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>

20419 printf-like functions.
20420 (tiff_load): Add casts to remove these marks before passing them
20421 to system-supplied API.
20423 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20425 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20426 This avoids several warnings with gcc -Wstrict-overflow.
20427 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20428 directly, rather than having caller test rule sign. This avoids
20429 some unnecessary tests.
20430 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20431 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20432 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20434 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20435 (xfont_open): Avoid unnecessary tests.
20437 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20439 * composite.h, composite.c (composition_gstring_put_cache):
20440 Use EMACS_INT, not int, for length.
20442 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20443 breaking out part of COMPOSITION_DECODE_RULE.
20444 (COMPOSITION_DECODE_RULE): Use it.
20445 * composite.c (get_composition_id): Remove unused local vars,
20446 by using the new macro.
20448 * textprop.c (set_text_properties_1): Change while to do-while,
20449 since the condition is always true at first.
20451 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20452 (interval_deletion_adjustment): Return unsigned value.
20455 * process.c (list_processes_1, create_pty, read_process_output):
20456 (exec_sentinel): Remove vars that were set but not used.
20457 (create_pty): Remove unnecessary "volatile"s.
20458 (Fnetwork_interface_info): Avoid possibility of int overflow.
20459 (read_process_output): Do adaptive read buffering even if carryover.
20460 (read_process_output): Simplify nbytes computation if buffered.

20464 * syntax.c (scan_words): Remove var that was set but not used.
20465 (update_syntax_table): Use unsigned instead of int.
20467 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
20468 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20469 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20471 * print.c (print_error_message): Avoid int overflow.
20473 * font.c (font_list_entities): Redo for clarity,
20474 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20476 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20477 (font_score): Avoid potential overflow in diff calculation.
20479 * fns.c (substring_both): Remove var that is set but not used.
20480 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20482 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20484 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20485 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20486 can always succeed if overflow has undefined behavior.
20488 * search.c (boyer_moore, wordify): Remove vars set but not used.
20489 (wordify): Omit three unnecessary tests.
20491 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20492 All callers changed. This avoids the need for an unused var.
20494 * casefiddle.c (casify_region): Remove var that is set but not used.
20496 * dired.c (file_name_completion): Remove var that is set but not used.
20498 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20500 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20501 (Finsert_file_contents): Remove unnecessary code checking fd.
20503 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20504 Check for integer overflow on size calculations.
20506 * buffer.c (Fprevious_overlay_change): Remove var that is set
20509 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20510 Remove vars that are set but not used.
20511 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20512 (timer_check_2): Mark vars as initialized.
20514 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20516 * image.c (lookup_image): Remove var that is set but not used.
20517 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20519 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20520 that are set but not used.
20522 * xfns.c (make_invisible_cursor): Don't return garbage
20523 if XCreateBitmapFromData fails (Bug#8410).
20525 * xselect.c (x_get_local_selection, x_handle_property_notify):
20526 Remove vars that are set but not used.
20528 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20529 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20531 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20532 Remove var that is set but not used.
20533 (scroll_bar_windows_size): Now size_t, not int.
20534 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20535 Check for overflow.
20537 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20538 (map_tty_color) [!defined MSDOS]: Likewise.
20540 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20542 * coding.c: Remove vars that are set but not used.
20543 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20544 All callers changed.
20545 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20546 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20547 (decode_coding_charset): Remove vars that are set but not used.
20549 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20550 that is set but not used.
20552 * print.c (print_object): Remove var that is set but not used.
20554 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20555 The gnulib version avoids calling malloc in the usual case,
20556 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20557 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20558 * filelock.c (current_lock_owner): Likewise.
20559 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20560 * sysdep.c: Include allocator.h, careadlinkat.h.
20561 (emacs_no_realloc_allocator): New static constant.
20562 (emacs_readlink): New function.
20563 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20564 ../lib/careadlinkat.h.
20566 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20568 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20569 first non-nil return value).
20571 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
20573 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
20574 if not defined (Bug#8403).
20576 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20578 * xdisp.c (display_count_lines): Remove parameter `start',
20579 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20580 (get_char_face_and_encoding): Remove parameter `multibyte_p',
20581 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

20583 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20584 and thereabouts. All callers changed.
20585 (get_per_char_metric): Remove parameter `f', unused since
20586 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20588 2011-04-02 Jim Meyering <meyering@redhat.com>
20590 do not dereference NULL upon failed strdup
20591 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20592 (ns_get_family): Likewise.
20594 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20596 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20598 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20600 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20603 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20605 Add lexical binding.
20607 * window.c (Ftemp_output_buffer_show): New fun.
20608 (Fsave_window_excursion):
20609 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20611 * lread.c (lisp_file_lexically_bound_p): New function.
20612 (Fload): Bind Qlexical_binding.
20613 (readevalloop): Remove `evalfun' arg.
20614 Bind Qinternal_interpreter_environment.
20615 (Feval_buffer): Bind Qlexical_binding.
20616 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20618 (syms_of_lread): Declare `lexical-binding'.
20620 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20622 * keyboard.c (eval_dyn): New fun.
20623 (menu_item_eval_property): Use it.
20625 * image.c (parse_image_spec): Use Ffunctionp.
20627 * fns.c (concat, mapcar1): Accept byte-code-functions.
20629 * eval.c (Fsetq): Handle lexical vars.
20630 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20631 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20632 (FletX, Flet): Obey lexical binding.
20633 (Fcommandp): Handle closures.
20634 (Feval): New `lexical' arg.
20635 (eval_sub): New function extracted from Feval. Use it almost
20636 everywhere where Feval was used. Look up vars in lexical env.
20638 (Ffunctionp): Move from subr.el.
20639 (Ffuncall): Handle closures.
20640 (apply_lambda): Remove `eval_flags'.
20641 (funcall_lambda): Handle closures and new byte-code-functions.
20642 (Fspecial_variable_p): New function.
20643 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20644 but without exporting it to Lisp.
20646 * doc.c (Fdocumentation, store_function_docstring):
20647 * data.c (Finteractive_form): Handle closures.
20649 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20652 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20654 (exec_byte_code): New function extracted from Fbyte_code to handle new
20655 calling convention for byte-code-functions. Add new byte-codes.
20657 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20659 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20661 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20663 * xdisp.c (redisplay_internal): Fix prototype.
20665 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20667 * xdisp.c (SCROLL_LIMIT): New macro.
20668 (try_scrolling): Use it when setting scroll_limit.
20669 Limit scrolling to 100 screen lines.
20670 (redisplay_window): Even when falling back on "recentering",
20671 position point in the window according to scroll-conservatively,
20672 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20674 (try_scrolling): When point is above the window, allow searching
20675 as far as scroll_max, or one screenful, to compute vertical
20676 distance from PT to the scroll margin position. This prevents
20677 try_scrolling from unnecessarily failing when
20678 scroll-conservatively is set to a value slightly larger than the
20679 window height. Clean up the case of PT below the margin at bottom
20680 of window: scroll_max can no longer be INT_MAX. When aggressive
20681 scrolling is in use, don't let point enter the opposite scroll
20682 margin as result of the scroll.
20683 (syms_of_xdisp) <scroll-conservatively>: Document the
20684 threshold of 100 lines for never-recentering scrolling.
20686 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20688 * dispextern.h (move_it_by_lines):
20689 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20690 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20691 (message_log_check_duplicate): Remove parameters `prev_bol' and
20692 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20693 (redisplay_internal): Remove parameter `preserve_echo_area',
20694 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20696 * indent.c (Fvertical_motion):
20697 * window.c (window_scroll_pixel_based, Frecenter):
20698 Don't pass `need_y_p' to `move_it_by_lines'.
20700 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20702 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20703 steal a few bits to be more compact.
20704 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20705 Remove unneeded casts.
20707 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20709 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20711 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20712 binding" message (bug#7967).
20714 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20716 Fix more problems found by GCC 4.6.0's static checks.
20718 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20719 Remove unused local var.
20721 * editfns.c (Fmessage_box): Remove unused local var.
20723 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20724 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20725 Omit unused local vars.
20726 * window.c (shrink_windows): Omit unused local var.
20727 * menu.c (digest_single_submenu): Omit unused local var.
20728 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20729 Omit unused local var.
20731 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20732 Don't assume string length fits in int.
20733 (keyremap_step, read_key_sequence): Use size_t for sizes.
20734 (read_key_sequence): Don't check last_real_key_start redundantly.
20736 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20737 instead of alloca (Bug#8344).
20739 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20740 (Fbacktrace_frame): Don't assume nframes fits in int.
20742 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20744 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20747 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20749 * cm.c (calccost): Turn while-do into do-while, for clarity.
20751 * keyboard.c (syms_of_keyboard): Use the same style as later
20752 in this function when indexing through an array. This also
20753 works around GCC bug 48267.
20755 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20757 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20759 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20760 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20762 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20763 This avoids undefined behavior on integer overflow, and is a bit
20764 more convenient anyway since it is compared to a size_t variable.
20766 Variadic C functions now count arguments with size_t, not int.
20767 This avoids an unnecessary limitation on 64-bit machines, which
20768 caused (substring ...) to crash on large vectors (Bug#8344).
20769 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20770 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

20778 * fns.c (concat): Likewise.
20779 * frame.c (x_set_frame_parameters): Likewise.
20780 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20781 0 if not found, not -1. All callers changed.
20783 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20784 (stack_copy_size): Now size_t, not int.
20785 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20787 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20789 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20790 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20791 All callers changed.
20793 * lisp.h (multibyte_char_to_unibyte):
20794 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20795 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

20803 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
20805 * keyboard.c (safe_run_hook_funcall): New function.
20806 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20807 don't set the hook to nil, but remove the offending function instead.
20808 (Qcommand_hook_internal): Remove, unused.
20809 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20810 Vcommand_hook_internal.
20812 * eval.c (enum run_hooks_condition): Remove.
20813 (funcall_nil, funcall_not): New functions.
20814 (run_hook_with_args): Call each function through a `funcall' argument.
20815 Remove `cond' argument, now redundant.
20816 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
20817 (Frun_hook_with_args_until_failure): Adjust accordingly.
20818 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

20824 * print.c (strout): Remove parameter `multibyte', unused since
20825 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
20827 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
20828 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20829 All callers changed.
20831 * w32.c (_wsa_errlist): Use braces for struct initializers.
20833 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
20834 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
20835 All callers changed.

20872 2011-03-26 Eli Zaretskii <eliz@gnu.org>
20874 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
20875 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
20877 2011-03-26 Juanma Barranquero <lekktu@gmail.com>

20978 2011-03-23 Julien Danjou <julien@danjou.info>
20980 * term.c (Fsuspend_tty, Fresume_tty):
20981 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
20982 * window.c (temp_output_buffer_show):

20990 * buffer.c (Fkill_all_local_variables):
20991 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20993 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20994 unconditionally since it does the check itself.
20996 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20998 Fix more problems found by GCC 4.5.2's static checks.
21000 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21001 the first time through the loop, since we know p0 < p1 then.
21002 This also avoids a gcc -Wstrict-overflow warning.
21004 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21005 leading to a memory leak, possible in functions like
21006 load_charset_map_from_file that can allocate an unbounded number
21007 of objects (Bug#8318).
21009 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21010 that could (at least in theory) be that large.
21012 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21013 This is less likely to overflow, and avoids undefined behavior if
21014 overflow does occur. All callers changed. Use strtoul to scan
21015 for the unsigned long integer.
21016 (pint2hrstr): Simplify and tune code slightly.
21017 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21027 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21030 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21032 * process.c (Fmake_network_process): Use socklen_t, not int,
21033 where POSIX says socklen_t is required in portable programs.
21034 This fixes a porting bug on hosts like 64-bit HP-UX, where
21035 socklen_t is wider than int (Bug#8277).
21036 (Fmake_network_process, server_accept_connection):
21037 (wait_reading_process_output, read_process_output):
21040 * process.c: Rename or move locals to avoid shadowing.

21050 Make tparam.h and terminfo.c consistent.
21051 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21052 Include tparam.h instead, since it declares them.
21053 * cm.h (PC): Remove extern decl; tparam.h now does this.
21054 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21055 * terminfo.c: Include tparam.h, to check interfaces.
21056 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21057 (tparam): Adjust signature to match interface in tparam.h;
21058 this removes some undefined behavior. Check that outstring and len
21059 are zero, which they always are with Emacs.
21060 * tparam.h (PC, BC, UP): New extern decls.
21062 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21063 (xftfont_open): Rename locals to avoid shadowing.

21077 * composite.c (composition_compute_stop_pos): Rename local to
21079 (composition_reseat_it): Remove unused locals.
21080 (find_automatic_composition, composition_adjust_point): Likewise.
21081 (composition_update_it): Mark var as initialized.
21082 (find_automatic_composition): Mark vars as initialized,
21083 with a FIXME (Bug#8290).

21087 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21088 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21089 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21090 to avoid shadowing.
21092 * textprop.c (property_change_between_p): Remove; unused.
21094 * intervals.c (interval_start_pos): Now static.
21096 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

21102 Fix pointer signedness.
21103 (alsa_choose_format): Remove unused local var.
21104 (wav_play): Initialize a variable to 0, to prevent undefined
21105 behavior (Bug#8278).
21107 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21109 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21111 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21112 clobbering (Bug#8298).
21113 * sysdep.c (sys_subshell): Likewise.
21114 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21116 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21117 This should get cleaned up, so that child_setup has the
21118 same signature on all platforms.
21120 * callproc.c (call_process_cleanup): Now static.
21121 (relocate_fd): Rename locals to avoid shadowing.
21123 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21125 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21126 not to be necessary, and produces flickering.
21128 2011-03-20 Glenn Morris <rgm@gnu.org>
21130 * config.in: Remove file.
21132 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
21134 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
21135 are now in src/globals.h.
21136 (syms_of_minibuf): Remove spurious & from previous change.

21176 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
21177 Define only if needed.
21179 * unexelf.c (unexec): Name an expression,
21180 to avoid gcc -Wbad-function-cast warning.
21181 Use a different way to cause a compilation error if anyone uses
21182 n rather than nn, a way that does not involve shadowing.
21183 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21185 * deps.mk (unexalpha.o): Remove; unused.
21187 New file unexec.h, the (simple) interface for unexec (Bug#8267).

21254 (Ftranslate_region_internal, Fformat):
21255 Rename or remove local vars to avoid shadowing.

21258 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
21261 * lisp.h (eassert): Check that the argument compiles, even if
21262 ENABLE_CHECKING is not defined.
21264 * data.c (Findirect_variable): Name an expression, to avoid
21265 gcc -Wbad-function-cast warning.

21282 (Fmemory_limit): Cast sbrk's returned value to char *.

21308 (RETALLOC_IF): Define only if needed.
21309 (WORDCHAR_P): Likewise. This one is never needed, but is used
21310 only in a comment talking about a compiler bug, so put inside
21311 the #if 0 of that comment.
21312 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
21313 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

21341 gcpro1, gcpro2, etc.
21342 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21344 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21345 argument, for consistency with GCPRO2_VAR, etc: it is now the

21349 Rename locals to avoid shadowing.
21351 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

21355 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...

21357 and the new implementation with inline functions needs to have
21358 current_buffer in scope now, rather than later when the macros
21360 (downcase, upcase1): New static inline functions.
21361 (DOWNCASE, UPCASE1): Reimplement using these functions.
21362 This avoids undefined behavior in expressions like
21363 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21364 from race conditions in accessing the global variables
21365 case_temp1 and case_temp2.
21366 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.

21377 (file_name_as_directory): Use const pointers when appropriate.
21378 (Fexpand_file_name): Likewise. In particular, newdir might
21379 point at constant storage, so make it a const pointer.

21393 so that gcc does not warn that these functions aren't declared.

21396 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
21397 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.

21403 * buffer.c (fix_overlays_before): Mark locals as initialized.
21404 (fix_start_end_in_overlays): Likewise. This function should be
21405 simplified by using pointers-to-pointers, but that's a different

21408 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
21409 (report_overlay_modification): Rename locals to avoid shadowing.

21414 to suppress a gcc -Wclobbered warning that does not seem to be right.
21415 (MAXPATHLEN): Define only if needed.
21417 * process.c (serial_open, serial_configure): Move decls from here ...
21418 * systty.h: ... to here, so that they can be checked.
21420 * fns.c (get_random, seed_random): Move extern decls from here ...
21421 * lisp.h: ... to here, so that they can be checked.
21423 * sysdep.c (reset_io): Now static.
21424 (wait_for_termination_signal): Remove; unused.
21426 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

21432 (describe_map_tree):
