1 2013-01-31 Glenn Morris <rgm@gnu.org>
3 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
4 (Fwrite_region): If coding-system-for-write is set, don't
5 call choose_write_coding_system. Move the last piece of
6 choose_write_coding_system here. (Bug#13522)
7 (syms_of_fileio): Add choose-write-coding-system.
9 2013-01-30 Eli Zaretskii <eliz@gnu.org>
11 * w32.c (sys_open): Zero out the flags for the new file descriptor.
12 (sys_close): Zero out the flags for the file descriptor before
13 closing it. (Bug#13546)
15 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
16 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
17 CharNextExA and CharPrevExA to iterate over file names encoded in
20 * w32.c (w32_get_long_filename, init_environment, readlink):
21 Support file names encoded in DBCS codepages.
22 (readlink): Use the current file-name-coding-system, not the ANSI
23 codepage, to decode and handle targets of symlinks.
25 2013-01-28 Eli Zaretskii <eliz@gnu.org>
27 * w32.c (opendir): Now accepts a 'const char *'.
29 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
31 Remove obsolete redisplay code. See the discussion at
32 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
33 * dispnew.c (preemption_period, preemption_next_check): Remove.
34 (Vredisplay_preemption_period): Likewise.
35 (update_frame, update_single_window, update_window, update_frame_1):
36 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
37 used, following the 2012-06-22 change.
39 2013-01-25 Eli Zaretskii <eliz@gnu.org>
41 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)

51 2013-01-25 Eli Zaretskii <eliz@gnu.org>
53 * w32.c (max_filename_mbslen): New function.
54 (normalize_filename, readdir): Use it to detect locales where ANSI
55 encoding of file names uses a double-byte character set (DBCS).
56 If a DBCS encoding is used, advance by characters using
57 CharNextExA, instead of incrementing a 'char *' pointer. Use
58 _mbslwr instead of _strlwr. (Bug#13515)
60 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
61 request of memory reservation to 1.7GB. (Bug#13065)
63 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
65 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
66 at check_extra_latin label. (Bug#13505)
68 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
70 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
71 Avoid redundant calls to strlen.
73 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
75 Drop async_visible and async_iconified fields of struct frame.
76 This is possible because async input is gone; for details, see
77 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
78 * frame.h (struct frame): Remove async_visible and async_iconified
79 members, convert garbaged to unsigned bitfield. Adjust comments.
80 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
81 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
82 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
83 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
84 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
86 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
87 properly. Likewise for obscured.
89 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
92 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
94 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
96 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
97 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
99 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
101 * xdisp.c (message2, message2_nolog): Remove functions.
102 (message3, message3_nolog): Extract nbytes and multibyteness directly
103 from the string. Change all callers.
104 (message3_nolog): Don't set message_enable_multibyte since set_message
105 will reset it anyway.
106 (message1, message1_nolog): Use message3.
107 (vmessage): Use a stack allocated buffer rather than f->message_buf.
108 (with_echo_area_buffer): Remove last two arguments. Update all callers.
109 (set_message): Drop all but the second arg, which has to be a string.
110 (set_message_1): Simplify now that we know that a1 is NULL and the
111 second arg is a string.
112 * frame.h (struct frame): Remove `message_buf' field.
113 Use glyphs_initialized_p instead.
114 (FRAME_MESSAGE_BUF): Remove macro.
115 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
116 * lisp.h (message2, message2_nolog): Remove declarations.
117 (message3, message3_nolog): Update declarations.
118 * keyboard.c (read_char_minibuf_menu_text)
119 (read_char_minibuf_menu_width): Remove vars.
120 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
121 to correctly handle multibyte strings.
122 * frame.c (delete_frame): Don't free message_buf any more.
123 * editfns.c (message_text, message_length): Remove vars.
124 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
125 * fileio.c (auto_save_error): Use message3 instead of message2.
126 * dispnew.c (adjust_frame_message_buffer): Remove function.
128 2013-01-23 Eli Zaretskii <eliz@gnu.org>
130 * w32term.c (w32fullscreen_hook): Account correctly for the screen
131 real estate used for the tool bar and the menu bar.
133 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
135 * insdel.c (prepare_to_modify_buffer): Force redisplay if
136 hidden buffer is prepared to modification (Bug#13164).
138 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
140 * window.h (struct window): Change window_end_valid member from
141 Lisp_Object to a bitfield. Adjust comments.
142 (wset_window_end_valid): Remove.
143 * window.c (adjust_window_count): Clear window_end_valid.
144 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
145 (Fwindow_line_height, set_window_buffer, Frecenter)
146 (Fsplit_window_internal, Fdelete_other_windows_internal)
147 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
148 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
149 * xdisp.c (check_window_end, reconsider_clip_changes)
150 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
151 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
152 (find_first_unchanged_at_end_row, try_window_id): Likewise.
154 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
156 * xdisp.c (mark_window_display_accurate): Simplify the loop
157 assuming that the only one of vchild, hchild or buffer window
158 slots is non-nil. Call mark_window_display_accurate_1 for
159 the leaf windows only.
160 (mark_window_display_accurate_1): Always assume leaf window.
163 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
165 * emacs.c (Qkill_emacs_hook): Now static.
167 * fileio.c (Finsert_file_contents): Simplify.
168 Remove unnecessary assignments and tests.
170 2013-01-21 Eli Zaretskii <eliz@gnu.org>
172 * w32.c (acl_set_file): Don't test for errors unless
173 set_file_security returns FALSE. Avoids spurious errors when
176 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
178 * fileio.c (Finsert_file_contents): Revert code introduced at
179 2013-01-18 in favor of the simpler and generally better fix.
180 Save stack space by removing 'buffer' and reusing 'read_buf'
183 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
185 * lisp.h (eabs): Define unconditionally (Bug#13419).
186 The old "#if !defined (eabs)" was an unnecessary revenant of back
187 when this macro was called "abs". Document 'eabs' better.
189 2013-01-19 Glenn Morris <rgm@gnu.org>
191 * fns.c (Frandom): Doc fix.
193 2013-01-19 Eli Zaretskii <eliz@gnu.org>
195 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
196 segfault when there are lots of overlays.
198 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
199 when there are lots of overlays. See
200 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
201 for the details and a way to reproduce.
203 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
205 * fileio.c: Use O_APPEND to append.
206 This corresponds better to the natural interpretation of "append",
207 and avoids the need to open the output file twice, or to invoke
208 lseek when APPEND is neither nil nor a number.
209 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
210 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
211 file possibly twice, and lseeking to its end; this avoids the
212 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
213 at the same time: the combination is never needed and apparently
214 it doesn't work with DOS_NT.
216 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
217 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
219 Allow floating-point file offsets.
220 Problem reported by Vitalie Spinu in
221 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
222 * fileio.c (emacs_lseek): Remove.
223 (file_offset): New function.
224 (Finsert_file_contents, Fwrite_region): Use it.
226 2013-01-19 Chong Yidong <cyd@gnu.org>
228 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
229 aborting on Fsignal (Bug#13289).
231 2013-01-19 Eli Zaretskii <eliz@gnu.org>
233 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
234 set_file_security as failure due to insufficient privileges.
235 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
236 (fstat): Return owner and group like 'stat' and 'lstat' do.
238 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
240 Work around bug in CIFS and vboxsf file systems (Bug#13149).
241 The bug was observed on Ubuntu operating inside a virtual machine,
242 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
243 The workaround introduces a race condition on non-buggy hosts,
244 but it's an unlikely race and anyway there's a nearly identical
245 nearby race that can't be fixed.
246 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
248 (Fwrite_region): Test for file system time stamp bug.
249 (init_fileio): New function.
250 * lisp.h (init_fileio): Declare it.
251 * emacs.c (main): Call it.
253 * fileio.c (Finsert_file_contents): Simplify new diagnostic
254 and make it more consistent with other stat-failure diagnostics.
256 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
258 Fix crash when inserting data from non-regular files. See
259 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
260 for the error description produced by valgrind.
261 * fileio.c (read_non_regular): Rename to read_contents.
262 Free Lisp_Save_Value object used to pass parameters.
263 (read_non_regular_quit): Rename to read_contents_quit.
264 (Finsert_file_contents): Redesign internal file reading loop to adjust
265 gap and end positions after each read and so help make_gap to work
266 properly. Do not signal an I/O error too early and so do not leave
267 not yet decoded characters in a buffer, which was the reason of
268 redisplay crash. Use list2 to build return value. Adjust comments.
270 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
272 Close a race when statting and reading files (Bug#13149).
273 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
274 This avoids a race if the file is renamed between stat and open.
275 This race is not the problem originally noted in Bug#13149;
276 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
278 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
280 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
281 objects, related functions and macros.
282 (make_save_value): Adjust prototype.

284 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
285 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
286 * alloc.c (format_save_value): Rename to make_save_value.
287 (make_save_pointer): New function.
288 (record_xmalloc): Use make_save_pointer.
289 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
290 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
291 Change users of make_save_value to make_save_pointer.
292 Likewise for format_save_value and make_save_value.
294 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
296 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.

308 (map_keymap_char_table_item): Adjust accordingly.
309 * fileio.c (non_regular_fd, non_regular_inserted)
310 (non_regular_nbytes): Remove.
311 (Finsert_file_contents): Convert trytry to ptrdiff_t. Use
312 format_save_value to pass parameters to read_non_regular.
313 (read_non_regular): Use XSAVE_ macros to extract parameters.
315 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
317 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
319 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
321 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
322 extraction from any Lisp_Save_Value slot. Add type checking.
323 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
324 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
325 * xselect.c: All users changed.
327 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
329 Some convenient bits to deal with Lisp_Save_Values.
330 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.
331 (allocate_misc): Remove prototype.
332 (format_save_value): New prototype.

337 * editfns.c (save_excursion_save): Use format_save_value.
338 (save_excursion_restore): Use XSAVE_OBJECT.
340 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
342 Avoid needless casts with XSAVE_POINTER.
343 * alloc.c (mark_object) [GC_MARK_STACK]:
344 * dired.c (directory_files_internal_unwind):
345 * fileio.c (do_auto_save_unwind):
346 * gtkutil.c (pop_down_dialog):
347 * keymap.c (map_keymap_char_table_item):
348 * lread.c (load_unwind):
349 * nsmenu.m (pop_down_menu):
350 * print.c (print_object) [GC_MARK_STACK]:
351 * xfns.c (clean_up_file_dialog):
352 * xmenu.c (cleanup_widget_value_tree):
353 Omit casts between XSAVE_POINTER and a pointer type.
355 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
357 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
358 * eval.c (eval_sub): Protect `form' from being GCed before its
359 car and cdr becomes protected with the backtrace entry.
361 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
363 Make Lisp_Save_Value more versatile storage for up to four objects.
364 * lisp.h (toplevel): Enumeration to describe types of saved objects.
365 (struct Lisp_Save_Value): New layout. Adjust comments.
366 (XSAVE_POINTER): New macro.
367 (XSAVE_INTEGER): Likewise.
368 (allocate_misc): Add prototype.
369 (free_misc): Likewise.
370 * alloc.c (allocate_misc): Now global.
371 (free_misc): Likewise. Adjust comment.
372 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
373 (free_save_value): Likewise.
374 (mark_object): Likewise.
375 * editfns.c (save_excursion_save): Pack everything within
376 Lisp_Save_Value and so avoid xmalloc.
377 (save_excursion_restore): Adjust to match new layout. Use free_misc
378 because we do not allocate extra memory any more. Add eassert.
379 * print.c (print_object): New code to print Lisp_Save_Value. Do not
380 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
381 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
382 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:
383 Use XSAVE_POINTER and XSAVE_INTEGER where appropriate.
385 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>
387 * nsfont.m (LCD_SMOOTHING_MARGIN): New define.
388 (nsfont_draw): Remove disabling of LCD smoothing.

392 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
394 Fix SIGDANGER handlers, for AIX (Bug#13408).
395 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
396 Move handlers here from emacs.c; they were out of place.
398 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
400 * xterm.c (syms_of_xterm): Adjust documentation for
401 scroll-bar-adjust-thumb-portion.
403 2012-12-31 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
405 * xterm.c (scroll-bar-adjust-thumb-portion): New variable to
406 determine whether scroll bar thumb size should be adjusted or
407 not. Use variable for MOTIF.
409 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for
412 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

421 (nsfont_open): Move block_input earlier. Add unblock_input before early
423 (nsfont_draw): Add block/unblock_input calls.
425 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
427 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
428 for old_charpos and old_bytepos.
430 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>
432 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
433 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
434 Clear tzvalbuf_in_environ if this workaround is in effect.
435 Problem and fix reported by Kazuhiro Ito.
437 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>
439 * insdel.c (Fcombine_after_change_execute, syms_of_insdel): Fix
440 ambiguous doc string cross-reference(s).
442 * keyboard.c (Fcommand_execute, syms_of_keyboard): Fix ambiguous
443 doc string cross-reference(s).
445 * window.c (Fwindow_point, syms_of_window): Fix ambiguous doc
446 string cross-reference(s).
448 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
450 Avoid unnecessary byte position calculation for the gap movement.
451 Since all users of move_gap do CHAR_TO_BYTE for other purposes
452 anyway, all of them should use move_gap_both instead.
453 * lisp.h (move_gap): Remove prototype.
454 * insdel.c (move_gap): Remove.
455 (move_gap_both): Add eassert.
456 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.
457 * xml.c (parse_region): Likewise.
459 2013-01-11 Paul Eggert <eggert@cs.ucla.edu>
461 emacsclient -t should not suspend Emacs server (Bug#13387)
462 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
464 * term.c (init_tty): Use them instead of rolling our own code.
465 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
466 switches from 'signal' to 'pthread_sigmask', which is safer in
467 multithreaded applications.
468 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
469 which has already arranged for that.
470 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
471 This is the main part of the bug fix.
473 2013-01-10 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)

541 2013-01-05 Eli Zaretskii <eliz@gnu.org>
543 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
544 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
545 digits for buffer positions, before misalignment starts.
546 Display "0" for integer "object" field.
547 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
548 Display the newline glyph more unambiguously.
550 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
552 * nsterm.m (ns_draw_underwave):
553 * w32term.c (w32_draw_underwave):
554 * xterm.c (x_draw_underwave): Make underwave look more triangular
555 and also degrade gracefully for small fonts. (Bug#13000)

584 2012-12-31 Eli Zaretskii <eliz@gnu.org>
586 * w32.c (unsetenv): Set up the string passed to _putenv
588 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
589 for the bug this caused.

607 Check toolbar_is_packed.
608 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
609 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
610 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
612 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
613 (xg_update_menubar): Update title only if
614 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
615 (xg_update_submenu): Skip tearoff only if

660 * fileio.c (file_name_as_directory, directory_file_name):
661 Accept an additional argument MULTIBYTE to indicate whether the input C
662 came from a multibyte or a unibyte Lisp string; all callers
663 adjusted. Don't assume the input string is always multibyte.
665 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
666 don't ENCODE_FILE them, and return a unibyte string if the input
668 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
669 don't assume the input strings will always be multibyte. If the

675 * lisp.h (toplevel): Add two notices to the comment about
676 defining a new Lisp data type.

680 * alloc.c (valid_lisp_object_p): Adjust comment.
682 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
684 * keyboard.c (record_asynch_buffer_change): Initialize an event
685 only if it's really needed.
686 * frame.h (enum output_method): Remove output_mac member since
687 it's a leftover from the deleted code.
688 * frame.c (Fframep): Adjust user here ...
689 * terminal.c (Fterminal_live_p): ... and here.
690 * coding.c (Qmac): Now here because it's only used to denote
691 end-of-line encoding type.
692 (syms_of_coding): DEFSYM it.
693 * frame.h (Qmac): Remove duplicated declaration.
695 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
697 * window.c (select_window_1): Now static, since it's used only here.

701 * window.c (window_body_cols): Subtract display margins from the
702 window body width on TTYs as well. See
703 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
704 for the original report.
706 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
708 * xdisp.c (redisplay_window): Remove inner local variable
709 because the outer shadowed one has the same meaning.
710 * xterm.h (struct x_output): Remove toolbar_detached member since it's
712 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
713 (xg_create_tool_bar): Adjust users.
715 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
717 * buffer.h (BUF_COMPACT): New macro to follow the common style.
718 * buffer.c (Fget_buffer_create): Use it to set compact field of
719 struct buffer_text to avoid accessing an uninitialized value
720 when compact_buffer is called for the first time.
721 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
722 (Fset_buffer_modified_p): Use buffer_window_count to check
723 whether the buffer is displayed in some window.
724 * xdisp.c (message_dolog): Likewise.
726 2012-12-23 Eli Zaretskii <eliz@gnu.org>
728 * w32.c (acl_set_file): If setting the file security descriptor
729 fails, and the new DACL is identical to the existing one, silently
730 return success. This fixes problems for users backing up their
731 own files without having the necessary privileges for setting
732 security descriptors.
734 * w32proc.c (reader_thread): Do not index fd_info[] with negative
736 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
737 after WaitForSingleObject returns normally. This expedites reader
738 thread shutdown when delete_child triggers it.
739 (reap_subprocess): More accurate commentary for why we call
740 delete_child only when cp->fd is negative.
742 * w32.c (sys_close): Do not call delete_child on a subprocess
743 whose handle is not yet closed. Instead, set its file descriptor
744 to a negative value, so that reap_subprocess will call
745 delete_child on that subprocess when its SIGCHLD arrives.
746 This avoids closing handles used for communications between sys_select
747 and reader_thread, which doesn't give sys_select a chance to
748 notice that the process exited and invoke the SIGCHLD handler for
751 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
753 * nsfns.m (Fns_do_applescript): Run event loop until script has

764 * w32term.c (w32fullscreen_hook): New function.
765 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
767 2012-12-21 Eli Zaretskii <eliz@gnu.org>
769 * fileio.c (Finsert_file_contents): Doc fix.
771 * w32proc.c (new_child, delete_child, find_child_pid): For a
772 subprocess, consider its slot being in use as long as its process
773 handle (procinfo.hProcess) is not NULL. This avoids reusing the
774 slot when a new process is started immediately after killing
775 another one, without waiting enough time for the first process to
776 be reaped and resources allocated for it be orderly freed.
778 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
780 2012-12-21 Chong Yidong <cyd@gnu.org>
782 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).

786 2012-12-21 Eli Zaretskii <eliz@gnu.org>
788 * w32.c (get_name_and_id): Always pass NULL as the first argument
789 of lookup_account_sid. Avoids crashes with UNC file names that
790 refer to DFS domains, not to specific machine names. (Bug#12621)
791 Remove now unused argument FNAME; all callers changed.
792 (get_file_owner_and_group): Remove now unused argument FNAME; all
795 2012-12-21 Chong Yidong <cyd@gnu.org>
797 * editfns.c (Finsert_char): Since read-char-by-name now signals an
798 error for invalid chars, don't check for a nil return value.
800 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
802 Avoid calls to CHAR_TO_BYTE if byte position is known.
803 * editfns.c (make_buffer_string_both): Use move_gap_both.
804 (Fbuffer_string): Use make_buffer_string_both.
805 * marker.c (buf_charpos_to_bytepos): Convert to eassert.

809 * fileio.c (Finsert_file_contents): Use move_gap_both.
810 * search.c (Freplace_match): Likewise.
811 * process.c (process_send_region): Likewise. Use convenient
812 names for byte positions.
813 * lisp.h (charpos_to_bytepos): Remove prototype.
814 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
815 * insdel.c (move_gap): Likewise.

824 (redisplay_internal): Don't bother selecting the frame to get the
825 proper value of frame-local variables (bug#13225).
827 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
829 * textprop.c (set_text_properties_1): Do not allow NULL interval.
830 Rename 4th argument since it may be buffer or string. Adjust comment.
831 * intervals.c (graft_intervals_info_buffer): Find an interval here.
833 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
835 * coding.c (Fdetect_coding_region): Do not check start and end with
836 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
837 (code_convert_region): Likewise.
839 2012-12-18 Eli Zaretskii <eliz@gnu.org>
841 * w32.c (acl_get_file, acl_set_file): Run the file name through

854 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
855 propagate redisplay's scrolling (if any) to the right window.
856 (redisplay_internal): Use ensure_selected_frame.
857 (display_mode_lines): Complete last fix.
858 * window.c (select_window_1): New func, extracted from select_window.
859 (select_window): Use it.
860 * window.h (select_window_1): Declare.

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

971 security APIs. This is to make most callers of 'stat' and
972 'lstat', which don't need that information, much faster.
974 * dired.c (Ffile_attributes) [WINDOWSNT]:
975 Set w32_stat_get_owner_group to a non-zero value, to request accurate
976 owner and group information from 'lstat'.
978 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
980 * fileio.c (Finsert_file_contents): Don't put tail into head area,
981 as that confuses set-auto-coding, so insist on the head-read
982 returning the full 1024 bytes. Let lseek compute the tail offset;
983 less work for us. Do not ignore I/O errors when reading the tail.
985 * xdisp.c: Minor style fixes.
986 (init_iterator): Hoist assignment out of if-expression.
987 (markpos_of_region): Callers now test for sign, not for -1.

1013 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1014 Remove unnecessary S_ISLNK test, as (contra the comments) this
1015 function can't copy symlinks. Improve quality of error message
1016 when attempting to copy files that are neither regular files nor

1027 2012-12-12 Daniel Colascione <dancol@dancol.org>
1029 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1030 the dumped Emacs is not a sparse file, greatly improving Cygwin
1031 "make bootstrap" performance.

1047 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1048 left_box_line_p and right_box_line_p flags of the glyph for R2L
1049 glyph rows. (Bug#13011)

1063 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1064 encoded_file_name, which is what it is.
1066 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

1092 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
1095 * w32fns.c (cache_system_info): Initialize the global hinst
1096 variable here so various initialization calls DTRT.
1098 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1099 (hinst): Remove unneeded extern declaration.
1100 (_start): Remove initialization of above variables; remove
1101 initialization of hinst, as cache_system_info now does that.

1249 * dbusbind.c (Fdbus_init_bus):
1251 * xterm.c (x_term_init):

1262 no longer needed here.

1264 Move to inside set_time_zone_rule; they don't need file scope any more.
1265 (set_time_zone_rule): Maintain the TZ=value string separately.
1266 (syms_of_editfns): Don't initialize initial_tz;
1267 init_editfns now does it.

1318 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1320 * frame.c (make_frame): Do not set window's buffer to t.
1321 * window.c (Fsplit_window_internal): Likewise. Previously it was
1322 used to indicate that the window is being set up. Now we use
1323 set_window_buffer for all new windows, so the condition in ...
1324 (Fset_window_buffer): ... is always true and can be removed.
1326 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1328 Convenient macro to check whether the buffer is hidden.
1329 * buffer.h (BUFFER_HIDDEN_P): New macro.

1355 Fix a recently-introduced delete-process race condition.
1356 * callproc.c, process.h (record_kill_process):
1357 New function, containing part of the old call_process_kill.
1358 (call_process_kill): Use it.
1359 This does not change call_process_kill's behavior.
1360 * process.c (Fdelete_process): Use record_kill_process to fix a
1361 race condition that could cause Emacs to lose track of a child.
1363 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1365 Avoid code duplication between prev_frame and next_frame.
1366 * frame.c (candidate_frame): New function. Add comment.

1369 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1371 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1372 fails, signal an error instead of continuing with an empty
1374 Encode expanded temp file pattern before passing it to mkstemp or
1377 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1378 Encode the file name before passing it to dostounix_filename, in
1379 case it will downcase it (under w32-downcase-file-names).
1382 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1384 Minor call-process cleanups.
1385 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1386 at the same time as other platforms, to simplify analysis.
1387 No need for fd0_volatile since we have synch_process_fd.
1388 Avoid needless emacs_close; arg is always negative.
1390 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1392 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous

1397 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1398 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer

1405 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1406 members to a bitfields.
1408 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1410 Don't let call-process be a zombie factory (Bug#12980).
1411 Fixing this bug required some cleanup of the signal-handling code.
1412 As a side effect, this change also fixes a longstanding rare race
1413 condition whereby Emacs could mistakenly kill unrelated processes,
1414 and it fixes a bug where a second C-g does not kill a recalcitrant
1415 synchronous process in GNU/Linux and similar platforms.
1416 The patch should also fix the last vestiges of Bug#9488,
1417 a bug which has mostly been fixed on the trunk by other changes.
1418 * callproc.c, process.h (synch_process_alive, synch_process_death)
1419 (synch_process_termsig, sync_process_retcode):
1420 Remove. All uses removed, to simplify analysis and so that
1421 less consing is done inside critical sections.
1422 * callproc.c (call_process_exited): Remove. All uses replaced
1423 with !synch_process_pid.
1424 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1425 These take the role of what used to be in unwind-protect arg.
1427 (block_child_signal, unblock_child_signal):
1428 New functions, to avoid races that could kill innocent-victim processes.
1429 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1430 (call_process_kill): Record killed processes as deleted, so that
1431 zombies do not clutter up the system. Do this inside a critical
1432 section, to avoid a race that would allow the clutter.
1433 (call_process_cleanup): Fix code so that the second C-g works again
1434 on common platforms such as GNU/Linux.
1435 (Fcall_process): Create the child process in a critical section,
1436 to fix a race condition. If creating an asynchronous process,
1437 record it as deleted so that zombies do not clutter up the system.
1438 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1439 light of these changes. Omit unnecessary call to emacs_close
1440 before failure, as the unwind-protect code does that.
1441 * callproc.c (call_process_cleanup):
1442 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1443 * process.c (record_deleted_pid): New function, containing
1444 code refactored out of Fdelete_process.
1445 (Fdelete_process): Use it.
1446 (process_status_retrieved): Remove. All callers changed to use
1447 child_status_change.
1448 (record_child_status_change): Remove, folding its contents into ...
1449 (handle_child_signal): ... this signal handler. Now, this
1450 function is purely a handler for SIGCHLD, and is not called after
1451 a synchronous waitpid returns; the synchronous code is moved to
1452 wait_for_termination. There is no need to worry about reaping
1453 more than one child now.
1454 * sysdep.c (get_child_status, child_status_changed): New functions.
1455 (wait_for_termination): Now takes int * status and bool
1456 interruptible arguments, too. Do not record child status change;
1457 that's now the caller's responsibility. All callers changed.
1458 Reimplement in terms of get_child_status.
1459 (wait_for_termination_1, interruptible_wait_for_termination):
1460 Remove. All callers changed to use wait_for_termination.
1461 * syswait.h: Include <stdbool.h>, for bool.
1462 (record_child_status_change, interruptible_wait_for_termination):
1464 (record_deleted_pid, child_status_changed): New decls.
1465 (wait_for_termination): Adjust to API changes noted above.
1467 * bytecode.c, lisp.h (Qbytecode): Remove.
1468 No longer needed after 2012-11-20 interactive-p changes.
1470 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1472 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1473 the scroll margin, move point outside the margin. (Bug#13055)

1483 (modify_region_1): ...new prototype.
1484 * textprop.c (modify_region): Now static. Adjust users.
1485 * insdel.c (modify_region): Rename to...
1486 (modify_region_1): ...new function to work with current buffer.
1487 Adjust comment and users. Use true and false for booleans.
1489 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1491 * alloc.c (free_save_value): New function.
1492 (safe_alloca_unwind): Use it.

1496 (save_excursion_restore): Adjust to match saved data structure.
1497 Use free_save_value to offload some work from GC. Drop obsolete
1500 2012-12-03 Chong Yidong <cyd@gnu.org>
1502 * fileio.c (Vauto_save_list_file_name): Doc fix.
1504 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1506 * w32fns.c: Remove prototype of atof.
1507 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1509 (file_dialog_callback): Make it UINT_PTR.
1511 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1514 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1515 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1518 2012-12-03 Glenn Morris <rgm@gnu.org>
1520 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1522 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1524 Fix xpalloc confusion after memory is exhausted.
1525 * alloc.c (xpalloc): Comment fix.
1526 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1527 and signals an error, do not clear charset_table_size, as
1528 charset_table is still valid.
1529 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1531 Use execve to avoid need to munge environ (Bug#13054).
1532 * callproc.c (Fcall_process):
1533 * process.c (create_process):
1534 Don't save and restore environ; no longer needed.
1535 * callproc.c (child_setup):
1536 Use execve, not execvp, to preserve environ.
1538 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1540 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1542 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1544 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1545 display for sliced images (Bug#10500).
1547 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1549 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1551 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1552 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1554 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1556 * xdisp.c (window_outdated): Remove eassert since it hits
1557 some suspicious corner cases (see Bug#13007 and Bug#13012).
1558 (mode_line_update_needed): New function.
1559 (redisplay_internal, redisplay_window): Use it.
1560 (ensure_selected_frame): New function.
1561 (redisplay_internal, unwind_redisplay): Use it.

1563 (buffer_shared_and_changed): ...near to its real use.
1565 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1567 * callproc.c (Fcall_process): Don't misreport vfork failure.
1569 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1571 * callproc.c (Fcall_process): Fix vfork portability problems.
1572 Do not assume that fd[0], count, filefd, and save_environ survive
1573 vfork. Fix bug whereby wrong errno value could be reported for
1574 pipe failure. Some minor cleanups, too, as follows. Move buf and
1575 bufsize to the context where they're needed. Change new_argv to
1576 be of type char **, as this is more convenient and avoids casts.
1577 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1578 Now local constants, not macros.
1580 2012-11-18 Kenichi Handa <handa@gnu.org>
1582 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"

1615 violations when repeatedly clicking on the "Top" link of the
1616 "bread-crumbs" in Info buffers.

1630 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1631 between bpos_covered and bpos_max. This fixes cursor display when
1632 several display strings follow each other.
1634 * .gdbinit (pgx): If the glyph's object is a string, display the
1635 pointer to string data, rather than the value of the string object
1636 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1638 * indent.c (Fvertical_motion): If the starting position is covered
1639 by a display string, return to one position before that, to avoid
1640 overshooting it inside move_it_to. (Bug#12930)
1642 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1644 * frame.h (struct frame): Remove display_preempted member

1647 * w32menu.c (pending_menu_activation): Remove since not
1649 (set_frame_menubar): Adjust user.
1650 * w32term.h (struct x_output): Drop outdated #if 0 code.

1653 Drop unused pending_menu_activation member.
1654 * xterm.h (struct x_output): Drop outdated #if 0 code.
1655 Use bitfields for explicit_parent, asked_for_visible,
1656 has_been_visible and net_wm_state_hidden_seen members.
1658 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1660 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1661 of a literal "/". (Bug#12955)
1662 (gl-stamp): Invoke fc.exe directly, not through cmd.

1667 * dired.c: Assume HAVE_DIRENT_H.
1668 (NAMLEN): Remove, replacing with ...
1669 (dirent_namelen): New function. All uses changed. Use the GNU macro
1670 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1671 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1672 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1673 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1675 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1676 * ndir.h: Rename to ../nt/inc/dirent.h.
1677 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1678 Do not include <dirent.h>; no longer needed.
1679 * w32.c: Include <dirent.h> rather than "ndir.h".
1681 2012-11-23 Chong Yidong <cyd@gnu.org>
1683 * xftfont.c (xftfont_open): Remove duplicate assignment.
1685 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1687 * alloc.c (Fgarbage_collect): Unblock input after clearing
1688 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1689 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1690 * msdos.c (IT_frame_up_to_date): Use it here...
1691 * w32term.c (w32_frame_up_to_date): ...here...
1692 * xterm.c (XTframe_up_to_date): ...and here...
1693 * nsterm.m (ns_frame_up_to_date): ...but not here.
1694 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1696 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1697 Do not check whether GC is in progress.

1701 * xdisp.c (window_buffer_changed): New function.
1702 (update_menu_bar, update_tool_bar): Use it to
1703 simplify large 'if' statements.

1705 'tail' and 'frame' local variables.
1707 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1709 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1710 with Windows system header.
1712 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1714 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1715 * alloc.c: Assume unistd.h exists.

1731 * emacs.c (main): Set the G_SLICE environment variable for all
1732 Cygwin builds, not just GTK builds. See
1733 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1735 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1737 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1738 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1739 Define for the MSVC compiler.
1741 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1743 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1744 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1745 dostounix_filename. Prevents crashes down the road, because
1746 dostounix_filename assumes it gets a unibyte string.
1747 Reported by Michel de Ruiter <michel@sentient.nl>, see

1783 2012-11-19 Daniel Colascione <dancol@dancol.org>
1785 * w32fns.c (Fx_file_dialog):
1786 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1787 cygwin_convert_file_name*.
1789 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1790 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1792 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1794 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1796 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1798 * w32select.c: Include w32common.h before w32term.h, so that
1799 windows.h gets included before w32term.h uses some of its
1800 features, see below.
1802 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1804 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

1815 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1816 Needed following 2012-10-20 change. (Bug#12902)
1818 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1820 * w32proc.c (waitpid): Remove unused label get_result.
1822 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1824 * makefile.w32-in (SYSWAIT_H): New macro.
1825 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1826 ($(BLD)/sysdep.$(O)): Update dependencies.

1832 * emacs.c, term.c (O_RDWR): Remove.
1833 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1834 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1835 * nsterm.m: Assume <fcntl.h> exists.
1836 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1837 (create_pty, Fmake_network_process, server_accept_connection)
1838 (wait_reading_process_output, init_process_emacs):
1840 (wait_reading_process_output): Put in a special case for WINDOWSNT
1841 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1842 It's not clear this is needed, but it's a more-conservative change.
1843 (create_process): Assume FD_CLOEXEC.
1844 (create_process, create_pty): Assume O_NOCTTY.
1845 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1846 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1847 Omit if not DOS_NT, since F_GETFL is not defined there.
1848 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1849 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1851 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1852 lack it, since gnulib guarantees this.
1853 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1855 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1857 * w32.c (faccessat): Pretend that directories have the execute bit
1858 set. Emacs expects that, e.g., in files.el:cd-absolute.
1860 * w32proc.c (create_child): Don't clip the PID of the child
1861 process to fit into an Emacs integer, as this is no longer a
1863 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1864 reaping only the process specified by PID argument, if that is
1865 positive. Use PID instead of dead_child to know which process to
1866 reap. Wait for the child to die only if WNOHANG is not in
1868 (sys_select): Don't set dead_child.
1870 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1871 as it is no longer needed.
1873 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1875 (record_child_status_change): Remove the setting of
1876 record_at_most_one_child for the !WNOHANG case.
1878 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1880 Fix problems in ns port found by static checking.
1881 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1882 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1883 not to process group.
1884 (ns_select): Use emacs_write, not write, as that's more robust
1885 in the presence of signals.
1886 (fd_handler:): Check for read errors.
1888 2012-11-16 Glenn Morris <rgm@gnu.org>
1890 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)

1898 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1899 use the same value of thread handle.
1900 (start_timer_thread): If the timer thread exited (due to error),
1901 clean up by closing the two handles it used. Duplicate the caller
1902 thread's handle here, so it gets duplicated only once, when
1903 launching the timer thread. Set priority of the timer thread, not
1905 (getitimer): Don't duplicate the caller thread's handle here.
1908 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1910 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1913 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1915 Remove no-longer-used pty_max_bytes variable.
1916 * process.c (pty_max_bytes): Remove; unused.
1917 (send_process): Do not set it.
1919 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1921 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1922 Update dependencies.
1924 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1926 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1927 This follows up on the 2012-09-29 patch that removed indirection
1928 for the 'function' field. Reported by Sergey Vinokurov in
1929 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1931 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1933 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1934 different name, as the MS runtime does not have such a function,
1935 and probably never will.) All callers changed. Ignore DIRFD
1936 value if PATH is an absolute file name, to match Posix spec
1937 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1940 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1942 * xdisp.c (echo_area_display, redisplay_internal):
1943 Omit redundant check whether frame_garbaged is set.
1945 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1947 Use faccessat, not access, when checking file permissions (Bug#12632).
1948 This fixes a bug that has been present in Emacs since its creation.
1949 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1950 which must set some sort of record. (Torek's bug report was against
1951 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1952 same common flaw.) See Torek's Usenet posting
1953 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1954 Posted: Fri Apr 8 14:18:56 1983.
1955 * Makefile.in (LIB_EACCESS): New macro.
1957 * callproc.c (init_callproc):
1958 * charset.c (init_charset):
1959 * fileio.c (check_existing, check_executable, check_writable)
1961 * lread.c (openp, load_path_check):
1962 * process.c (allocate_pty):
1964 Use effective UID when checking permissions, not real UID.
1965 * callproc.c (init_callproc):
1966 * charset.c (init_charset):
1967 * lread.c (load_path_check, init_lread):
1968 Test whether directories are accessible, not merely whether they exist.
1969 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1970 * fileio.c (check_existing, check_executable, check_writable)
1972 Use symbolic names instead of integers for the flags, as they're
1974 (check_writable): New arg AMODE. All uses changed.
1975 Set errno on failure.
1976 (Ffile_readable_p): Use faccessat, not stat + open + close.
1977 (Ffile_writable_p): No need to call check_existing + check_writable.
1978 Just call check_writable and then look at errno. This saves a syscall.
1979 dir should never be nil; replace an unnecessary runtime check
1980 with an eassert. When checking the parent directory of a nonexistent
1981 file, check that the directory is searchable as well as writable, as
1982 we can't create files in unsearchable directories.
1983 (file_directory_p): New function, which uses 'stat' on most platforms
1984 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1985 (Ffile_directory_p, Fset_file_times): Use it.
1986 (file_accessible_directory_p): New function, which uses a single
1987 syscall for efficiency.
1988 (Ffile_accessible_directory_p): Use it.
1989 * xrdb.c (file_p): Use file_directory_p.
1990 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1991 * lread.c (openp): When opening a file, use fstat rather than
1992 stat, as that avoids a permissions race. When not opening a file,
1993 use file_directory_p rather than stat.
1994 (dir_warning): First arg is now a usage string, not a format.
1995 Use errno. All uses changed.
1996 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1997 that merely introduced a race.
1998 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1999 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2000 and similarly for the other O_* flags.
2001 * w32.c (sys_faccessat): Rename from sys_access and switch to
2002 faccessat's API. All uses changed.
2003 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2004 (magic_db): Rename from magic_file_p.
2005 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2006 char *, so that we don't have to test for file existence
2007 separately from opening the file for reading. This removes a race
2008 fixes a permission-checking problem, and simplifies the code.
2010 (file_p): Remove; no longer needed.
2012 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2014 Omit glyphs initialization at startup.
2015 * dispnew.c (glyphs_initialized_initially_p): Remove.
2016 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2017 (Fredraw_frame): Move actual code from here...
2018 (redraw_frame): ...to here. Add eassert. Adjust comment.
2019 (Fredraw_display): Use redraw_frame.
2020 * xdisp.c (clear_garbaged_frames): Likewise.
2022 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2024 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2025 passed to pint2str and pint2hrstr to be at most the size of the
2026 frame's decode_mode_spec_buffer. This avoids crashes with very
2027 large values of FIELD_WIDTH argument to decode_mode_spec.
2030 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2032 Fix a race with verify-visited-file-modtime (Bug#12863).
2033 Since at least 1991 Emacs has ignored an mtime difference of no
2034 more than one second, but my guess is that this was to work around
2035 file system bugs that were fixed long ago. Since the race is
2036 causing problems now, let's remove that code.
2037 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2038 whose time stamp is off by no more than a second. Insist that the
2039 file time stamps match exactly.
2041 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2043 * frame.h (struct frame): Convert external_tool_bar member to
2044 1-bit unsigned bitfield.
2045 * termhooks.h (struct terminal): Remove mouse_moved member since
2046 all users are long dead. Adjust comment on mouse_position_hook.
2048 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2050 Simplify by using FOR_EACH_FRAME here and there.
2051 * frame.c (next_frame, prev_frame, other_visible_frames)
2052 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2053 * w32term.c (x_window_to_scroll_bar): Likewise.
2054 * window.c (window_list): Likewise.
2055 * xdisp.c (x_consider_frame_title): Likewise.
2056 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2057 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2058 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2059 * xmenu.c (menubar_id_to_frame): Likewise.
2060 * xselect.c (frame_for_x_selection): Likewise.
2061 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2062 (x_window_to_menu_bar): Likewise.
2063 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2065 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2067 * data.c (Qdefalias_fset_function): Now static.
2069 Another tweak to vectorlike_header change.
2070 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2071 Remove, and replace all uses with ...
2072 (next_in_free_list, set_next_in_free_list):
2073 New functions, which respect C's aliasing rules better.
2075 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2077 * window.c (list4i): Rename from 'quad'. All uses changed.
2078 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2080 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2082 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2083 warning about mixing declarations and code in ISO C90.
2085 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2087 * window.c (Fsplit_window_internal): Set combination limit of
2088 new parent window to t iff Vwindow_combination_limit is t;
2089 fixing a regression introduced with the change from 2012-09-22.
2090 (Fset_window_combination_limit): Fix doc-string.
2092 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2094 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2095 amount when the scroll margins are too large. When scrolling
2096 backwards in the buffer, give up if cannot reach point or the
2097 scroll margin within a reasonable number of screen lines.
2098 Fixes point position in window under scroll-up/down-aggressively when
2099 point is positioned many lines beyond the window top/bottom.
2102 * ralloc.c (relinquish): If real_morecore fails to return memory
2103 to the system, don't crash; instead, leave the last heap
2104 unchanged and return. (Bug#12774)
2106 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2108 * lisp.h (AUTOLOADP): New macro.
2109 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2110 * data.c (Ffset): Remove special ad-advice-info handling.
2111 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2113 (Finteractive_form): Simplify.
2114 (Fquo): Don't insist on having at least 2 arguments.
2115 (Qdefalias_fset_function): New var.
2117 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2119 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2121 * nsfont.m (Qcondensed, Qexpanded): New variables.
2122 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2123 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2125 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2127 Fix recently introduced crash on MS-Windows (Bug#12839).
2128 * w32term.h (struct scroll_bar): Use convenient header.
2129 (SCROLL_BAR_VEC_SIZE): Remove.
2130 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2132 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2134 Tweak last vectorlike_header change.
2135 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2136 vectorlike object on the free list. This is introduced to avoid
2137 some (but not all) pointer casting and aliasing problems, see
2138 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2139 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2141 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2143 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2145 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2146 been removed, so remove them here also.
2148 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2150 * doc.c (Fdocumentation): Handle new property
2151 dynamic-docstring-function to replace the old ad-advice-info.
2153 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2155 * fns.c (Qeql, hashtest_eq): Now static.
2157 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2159 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2160 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2161 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2162 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2164 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2166 Use same hash function for hashfn_profiler as for hash_string etc.
2167 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2168 * lisp.h (sxhash_combine): New inline function, with the contents
2169 of the old SXHASH_COMBINE.
2170 * profiler.c (hashfn_profiler): Use it, instead of having a
2171 special hash function containing a comparison that always yields 1.
2173 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2175 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2176 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2177 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2180 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2182 * image.c (xpm_make_color_table_h): Fix compiler error because
2183 make_hash_table changed.
2185 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2187 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2189 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2191 Use ad-hoc comparison function for the profiler's hash-tables.
2192 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2193 (make_log): Use them.
2194 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2195 call Fequal any more.

2204 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2205 (hash_lookup, hash_remove_from_table): Move assertion checking of
2206 hashfn result here. Check hash-equality before calling cmpfn.

2216 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2218 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2219 value of w32-scroll-lock-modifier is neither nil nor one of the
2220 known key modifiers. (Bug#12806)
2222 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2224 Shrink struct vectorlike_header to the only size field.
2225 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2227 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2228 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2229 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2230 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2231 information from the vector header. Adjust comment.
2232 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
2233 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
2235 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.

2241 (enum mem_type): Adjust comment.
2242 (NEXT_IN_FREE_LIST): New macro.
2243 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2244 (Fmake_bool_vector): Likewise.
2245 (struct large_vector): New type to represent allocation unit for
2246 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2247 (large_vectors): Change type to struct large_vector.
2248 (allocate_vector_from_block): Simplify.
2249 (PSEUDOVECTOR_NBYTES): Replace with...
2250 (vector_nbytes): ...new function. Adjust users.
2251 (sweep_vectors): Adjust processing of large vectors.
2252 (allocate_vectorlike): Likewise.
2253 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2254 Add easserts. Adjust XSETPVECTYPESIZE usage.
2255 (allocate_buffer): Use BUFFER_PVEC_INIT.
2256 (live_vector_p): Adjust to match large vector.
2257 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2258 * buffer.h (struct buffer): Add next member.
2259 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2261 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2262 * fns.c (internal_equal): Adjust to match enum pvec_type change.

2264 * lread.c (defsubr): Use XSETPVECTYPE.
2265 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
2266 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
2267 (xvecsize): New command.
2269 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2271 * keyboard.c (event_to_kboard): Do not dereference
2272 frame_or_window field of SELECTION_REQUEST_EVENT
2273 and SELECTION_CLEAR_EVENT events (Bug#12814).
2274 * xterm.h (struct selection_input_event): Adjust comment.
2276 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2278 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2279 such as Scroll Lock, if the respective keys are treated as
2280 function keys, not as modifiers. This avoids destroying non-ASCII
2281 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2283 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2285 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2287 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2289 Restore some duplicate definitions (Bug#12814).
2290 This undoes part of the 2012-11-03 changes. Some people build
2291 with plain -g rather than with -g3, and they need the duplicate
2292 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2293 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2294 Define as macros, as well as as enums or as constants.
2296 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2298 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2299 to keypad keys (Bug#12816).
2301 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2303 Minor adjustments of recently-changed frame functions.
2304 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2305 known to be a frame (we're in the FRAMEP branch).
2306 * lisp.h (Qframep): Remove decl. frame.h declares this.
2307 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2308 since they're meant for Lisp fixnum values.
2310 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2312 * window.c (Fwindow_combination_limit): Revert to the only
2313 required argument and adjust docstring as suggested in
2314 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2315 by Martin Rudalics <rudalics@gmx.at>.
2317 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2319 Widely used frame validity and checking functions.
2320 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.

2324 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2325 (Fframe_pointer_visible_p): Use decode_any_frame.
2326 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2327 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2328 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2329 (Fframe_focus): Likewise. Allow zero number of arguments.
2331 (frame_buffer_list, frame_buffer_predicate): Remove.
2332 * lisp.h (frame_buffer_predicate): Remove prototype.
2333 * buffer.c (Fother_buffer): Use decode_any_frame.
2334 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2335 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2336 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2337 (Fclose_font, Ffont_info): Use decode_live_frame.
2338 * fontset.c (check_fontset_name): Likewise.
2339 * terminal.c (Fframe_terminal): Likewise.
2340 * w32fns.c (check_x_frame): Likewise.
2341 * window.c (Fminibuffer_window, Fwindow_at)
2342 (Fcurrent_window_configuration): Likewise.
2343 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2344 Likewise. Allow zero number of arguments. Adjust docstring.
2345 * dispnew.c (Fredraw_frame): Likewise.
2346 * xfaces.c (frame_or_selected_frame): Remove.
2347 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2348 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2349 (Fframe_face_alist): Use decode_live_frame.
2350 * xfns.c (check_x_frame): Likewise.
2352 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2354 * window.c (quad): New function.
2355 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2356 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2357 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2358 (Fwindow_line_height): Use it.
2359 (Fwindow_fringes): Use list3.
2360 (Fwindow_scroll_bars): Use list4.
2361 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2362 (Fwindow_combination_limit): Allow zero number of arguments.
2364 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2366 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2368 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2369 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2370 file descriptor 2 for standard error. (Bug#12805)
2372 2012-11-05 Chong Yidong <cyd@gnu.org>
2374 * process.c (wait_reading_process_output): Revert previous change.
2376 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2378 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2379 This removes code that has been obsolete since around 1990.
2380 * callproc.c (Fcall_process):
2382 * process.c (create_process):
2383 * term.c (dissociate_if_controlling_tty):
2384 Assume setsid exists.
2385 * callproc.c (child_setup): Assume setpgid exists and behaves as
2386 per POSIX.1-1988 or later.
2387 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2388 * emacs.c (shut_down_emacs):
2389 * sysdep.c (sys_suspend, init_foreground_group):
2390 Assume getpgrp behaves as per POSIX.1-1998 or later.
2391 * msdos.c (setpgrp): Remove.
2392 (tcgetpgrp, setpgid, setsid): New functions.
2393 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2394 * term.c (no_controlling_tty): Remove; unused.
2395 * w32proc.c (setpgrp): Remove.
2396 (setsid, tcgetpgrp): New functions.
2398 Simplify by assuming __fpending.
2399 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2400 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2401 Do not assume that __fpending's result fits in int.
2403 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2405 Remove EMACS_OUTQSIZE+sleep hack.
2406 * dispnew.c (update_frame_1): Remove hack for terminals slower
2407 than 2400 bps, which throttled Emacs by having it sleep.
2408 This code hasn't worked since at least 2007, when the multi-tty stuff
2409 was added, and anyway those old terminals are long dead.
2410 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2411 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2413 Fix data-loss with --version (Bug#9574).
2414 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2415 as we can't assume that emacs_strerror is initialized, and strerror
2416 is good enough here.
2417 (main): Invoke atexit earlier, to catch earlier instances of
2418 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2420 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2422 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2423 (keyDown): Remap keypad keys to X11 virtual key codes.
2425 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2427 Fix data-loss with --batch (Bug#9574).
2428 * emacs.c: Include <close-stream.h>.
2429 (close_output_streams): New function.
2430 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2431 and handles errors appropriately.
2432 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2435 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2436 The symptom is a diagnostic "GLib-WARNING **: In call to
2437 g_spawn_sync(), exit status of a child process was requested but
2438 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2439 waitpid(), so exit status can't be returned." The diagnostic
2440 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2441 The real bug is a race condition between Emacs and glib: Emacs
2442 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2443 so that glib can't find it. Work around the bug by invoking
2444 waitpid only on subprocesses that Emacs itself creates.
2445 * process.c (create_process, record_child_status_change):
2446 Don't use special value -1 in pid field, as the caller now must
2447 know the pid rather than having the callee infer it.
2448 The inference was sometimes incorrect anyway, due to another race.
2449 (create_process): Set new 'alive' member if child is created.
2450 (process_status_retrieved): New function.
2451 (record_child_status_change): Use it.
2452 Accept negative 1st argument, which means to wait for the
2453 processes that Emacs already knows about. Move special-case code
2454 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2455 processes that have already been waited for, by testing and
2456 clearing new 'alive' member.
2457 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2458 now does this internally.
2459 (handle_child_signal): Let record_child_status_change do all
2460 the work, since we do not want to reap all exited child processes,
2461 only the child processes that Emacs itself created.
2462 * process.h (Lisp_Process): New boolean member 'alive'.
2464 Omit duplicate definitions no longer needed with gcc -g3.
2465 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2466 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2467 Define only as macros. There's no longer any need to also define
2468 these symbols as enums or as constants, since we now assume
2469 gcc -g3 when debugging.
2471 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2473 * lisp.mk: Adjust comments to the fact that term/internal is now
2474 loaded from loadup.el.
2476 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2477 (msdos_fatal_signal): New function.
2478 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2481 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2482 for GCC versions before 4.
2483 (emacs_raise): Define to call msdos_fatal_signal.
2485 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2486 iterator when starting in the middle of a display or overlay
2489 2012-11-03 Chong Yidong <cyd@gnu.org>
2491 * process.c (wait_reading_process_output): Clean up the last
2494 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2496 * process.c (wait_reading_process_output): Avoid a race condition
2497 with SIGIO delivery (Bug#11536).
2499 2012-11-03 Chong Yidong <cyd@gnu.org>
2501 * buffer.c (cursor_type): Untabify docstring.
2503 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2505 * frame.h (struct frame): Drop can_have_scroll_bars member
2506 which is meaningless for a long time. Adjust comments.
2507 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2508 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2510 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2512 * window.c (decode_next_window_args): Update window arg after
2513 calling decode_live_window and so fix crash reported at
2514 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2515 by Juanma Barranquero <lekktu@gmail.com>.
2516 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2517 * font.c (Ffont_at): Likewise.
2519 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2521 * widget.c (resize_cb): New function.
2522 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2523 (EmacsFrameResize): Check if all is up to date before changing frame
2526 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2528 Implement backtrace output for fatal errors on MS-Windows.
2529 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2530 (BACKTRACE_LIMIT_MAX): New macro.
2531 (w32_backtrace): New function.
2532 (emacs_abort): Use w32_backtrace when the user chooses not to
2533 attach a debugger. Update the text of the abort dialog.
2535 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2537 Window-related stuff cleanup here and there.
2538 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2539 Use decode_any_window.
2540 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2541 * xdisp.c (Fformat_mode_line): Likewise.
2542 * font.c (Ffont_at): Use decode_live_window.
2543 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2544 * window.c (decode_next_window_args): Likewise.
2545 (decode_any_window): Remove static.
2546 * window.h (decode_any_window): Add prototype.
2547 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2548 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2551 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2553 Remove pad from struct input_event.
2554 * termhooks.h (struct input_event): Remove padding field.
2556 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2557 member is never cons for a long time. Adjust comment.
2558 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2559 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2560 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2561 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2563 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2565 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2567 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2569 Fix crash when using Emacs as commit editor for git (Bug#12697).
2570 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2571 and it is configured in conf_post.h.
2572 (Fcall_process): Don't invoke both setsid and setpgid; the former
2573 is enough, if it exists.
2574 * callproc.c (Fcall_process, child_setup):
2575 * process.c (create_process): Use setpgid.
2576 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2578 * dispnew.c (init_display): Initialize the foreground group
2579 if we are running a tty display.
2580 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2581 * lisp.h (init_foreground_group): New decl.
2582 * sysdep.c (inherited_pgroup): New static var.
2583 (init_foreground_group, tcsetpgrp_without_stopping)
2584 (narrow_foreground_group, widen_foreground_group): New functions.
2585 (init_sys_modes): Narrow foreground group.
2586 (reset_sys_modes): Widen foreground group.
2588 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2590 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2592 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2594 * minibuf.c (read_minibuf): Restore current buffer since
2595 choose_minibuf_frame calling Fset_frame_selected_window may
2596 change it (Bug#12766).
2598 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2600 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2602 2012-10-30 Kenichi Handa <handa@gnu.org>
2604 * font.c (Ffont_at): If WINDOW is specified and it is not
2605 displaying the current buffer, signal an error.
2607 2012-10-29 Daniel Colascione <dancol@dancol.org>
2609 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2610 In preparation for fixing bug#12739, move these functions from
2613 * coding.h, coding.c: ... to here, and compile them only when
2614 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2615 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2617 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2619 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2620 (timer_loop, getitimer, setitimer): Use it instead of
2621 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2623 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2626 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2628 * nsterm.m (NO_APPDEFINED_DATA): New define.
2629 (last_appdefined_event_data): New variable
2630 (last_appdefined_event): Remove.
2631 (ns_select): Initialize t from last_appdefined_event_data instead
2632 of [last_appdefined_event data1].
2633 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2634 remove last_appdefined_event (Bug#12698).
2636 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2638 * frame.c (x_set_font): Catch internal error.
2640 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2642 Avoid overflow in w32 implementation of interval timers.
2643 When possible, for ITIMER_PROF count only times the main thread
2645 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2646 'volatile ULONGLONG' types. All the other data which was
2647 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2648 (GetThreadTimes_Proc): New typedef.
2649 (w32_get_timer_time): New function, returns a suitable time value
2651 (timer_loop): Enter critical section when accessing ULONGLONG
2652 values of the itimer_data struct, as these accesses are no longer
2653 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2654 Remove unused variable.
2655 (init_timers): Initialize s_pfn_Get_Thread_Times.
2656 (start_timer_thread): Don't assign itimer->caller_thread here.
2657 (getitimer): Assign itimer->caller_thread here.
2658 (setitimer): Always call getitimer to get the value of ticks_now.
2659 (sys_spawnve): Avoid compiler warning about format mismatch.
2661 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2663 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2664 mouse movement events if the menu bar is active. This avoids
2665 producing a busy "hour-glass" cursor by Windows if the mouse
2666 pointer is positioned over a tooltip shown for some menu item.
2668 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2670 Don't assume process IDs fit in int.
2671 * emacs.c (shut_down_emacs) [!DOS_NT]:
2672 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2673 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2674 Use pid_t, not int, to store process IDs, as 'int'
2675 is not wide enough on a few platforms (e.g., AIX and IRIX).
2677 2012-10-23 Kenichi Handa <handa@gnu.org>
2679 The following change is to make face-font-rescale-alist work
2680 correctly for non-ASCII fonts.
2682 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2683 (font_open_for_lface): Handle Vface_font_rescale_alist.
2685 2012-10-23 Chong Yidong <cyd@gnu.org>
2687 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2689 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
2691 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
2693 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2695 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2698 2012-10-21 Glenn Morris <rgm@gnu.org>
2700 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2702 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2704 Port to OpenBSD 5.1.
2705 * frame.c (Fmouse_position, Fmouse_pixel_position):
2706 * xdisp.c (produce_stretch_glyph):
2707 Declare local vars only when they're needed.
2708 This is clearer and avoids a warning on OpenBSD about unused vars.
2709 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2710 This is safer, and avoids OpenBSD warnings about unused vars.
2711 * keyboard.c (record_menu_key): Remove unnecessary decl.
2712 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2713 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2714 as our definition clashes with OpenBSD's.
2715 * xfaces.c (load_face_colors, check_lface_attrs)
2716 (get_lface_attributes_no_remap, get_lface_attributes)
2717 (lface_fully_specified_p, x_supports_face_attributes_p)
2718 (tty_supports_face_attributes_p, face_fontset, realize_face)
2719 (realize_x_face, realize_tty_face):
2720 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2721 merely Lisp_Object *. This is more informative and avoids
2722 a warning on OpenBSD about accessing beyond an object's size.
2724 2012-10-20 Chong Yidong <cyd@gnu.org>
2726 * lread.c (Fload): Doc fix (Bug#12592).
2728 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2730 * font.c (Ffont_at): Fix previous change.
2732 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2734 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2735 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
2738 * alloc.c (NSTATICS): Decrease to 0x800.
2740 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
2742 * fns.c (Fnreverse): Include the problem element when signaling an
2745 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
2747 * nsterm.m (ns_select): Check writefds before call to
2748 FD_ISSET (Bug#12668).
2750 2012-10-18 Daniel Colascione <dancol@dancol.org>
2752 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2753 (staticpro): If we run out of staticpro slots, die with an
2754 informative error instead of just calling emacs_abort.
2756 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2758 Fix two flaws reported by Dmitry Antipov.
2759 * window.c (Ftemp_output_buffer_show): Remove.
2760 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
2761 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
2763 2012-10-17 Eli Zaretskii <eliz@gnu.org>
2765 * makefile.w32-in ($(BLD)/w32.$(O)):
2766 ($(BLD)/vm-limit.$(O)):
2768 ($(BLD)/unexw32.$(O)):
2769 ($(BLD)/fileio.$(O)):
2770 ($(BLD)/dispnew.$(O)): Update dependencies.
2772 * w32term.h (w32_initialize_display_info, initialize_w32_display):
2775 * w32proc.c: Include ctype.h.
2777 * w32.h (init_environment, check_windows_init_file)
2778 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
2779 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
2780 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
2781 (sys_link): Add prototypes.
2783 * w32.c: Include w32select.h.
2784 (sys_access, e_malloc, sys_select): Add prototypes.
2785 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
2787 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
2789 * unexw32.c: Include lisp.h and w32.h.
2791 * term.c [WINDOWSNT]: Include w32term.h.
2793 * process.c [WINDOWSNT]: Add prototype of sys_select.

2855 * image.c (init_tiff_functions, init_imagemagick_functions)
2856 (init_svg_functions): Fix cygw32 build break by using these
2857 functions only when WINDOWSNT _and_ HAVE_NTGUI.

2878 Fix some stat-related races.
2879 * fileio.c (Fwrite_region): Avoid race condition if a file is

2912 * fileio.c (check_existing): New function.
2913 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
2914 instead of calling 'stat', when what's needed is to check whether
2915 a file exists. This avoids expensive system calls on MS-Windows.
2918 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
2920 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

3010 (detect_input_pending_run_timers):
3011 * process.c (wait_reading_process_output):
3012 Use unsigned for counter where wraparound-on-overflow is desired,
3013 since unsigned is guaranteed to have that behavior and signed is not.
3014 (read_char): Use ptrdiff_t for string length.
3015 (get_input_pending): Remove first argument, since it was always
3016 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3017 and behave as if it had that value. Return new value of
3018 input_pending. All callers changed.
3019 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3020 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
3022 * keymap.c (push_key_description): Omit last arg, which was always 1.
3023 All callers changed.
3025 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
3027 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

3043 Don't include termopts.h.
3045 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
3047 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3049 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3051 * commands.h (immediate_quit): Remove duplicate decl.
3053 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3055 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

3058 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3060 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3062 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3063 match what GetLastError returns. Explain why the function is
3066 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3067 'is_tooltip_frame', to avoid confusion with its global namesake.
3069 2012-10-08 Daniel Colascione <dancol@dancol.org>
3071 * xdisp.c (start_hourglass): Call w32_note_current_window when
3072 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3073 build that caused Emacs to display the hourglass cursor forever.
3075 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3076 which is broken under remote desktop, calculate the number of
3077 colors available for a display based on the display's number of
3078 planes and number of bits per pixel per plane. (bug#10397).
3080 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3082 * nsfont.m (Vfonts_in_cache): New variable.
3083 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3084 are used. Add cached fonts to Vfonts_in_cache.
3085 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3087 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3089 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3091 (FONT_H): Define after FRAME_H.
3092 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3093 Update dependencies.
3095 * w32term.c: Remove leftover declaration of keyboard_codepage.
3097 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3099 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3100 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3101 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3102 (GLOBAL_SOURCES): Add cygw32.c.
3103 ($(BLD)/unexw32.$(O)):
3105 ($(BLD)/w32console.$(O)):
3106 ($(BLD)/w32fns.$(O)):
3107 ($(BLD)/w32heap.$(O)):
3108 ($(BLD)/w32menu.$(O)):
3109 ($(BLD)/w32proc.$(O)): Add w32common.h.
3111 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3113 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3115 2012-10-08 Daniel Colascione <dancol@dancol.org>
3117 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3118 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3119 accidental message numbering hole. Change other messages to
3122 * w32select.h (HAVE_W32SELECT): Remove.
3124 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3125 w32common.h instead of w32heap.h.
3127 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3128 (get_allocation_unit, get_processor_type, get_w32_major_version)
3129 (get_w32_minor_version, sysinfo_cache, osinfo_cache)

3131 (OS_NT, os_subtype, cache_system_info): Move declarations to
3134 * w32heap.c: Include w32common.h.
3135 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3136 (w32_minor_version, w32_build_number, w32_subtype):
3137 Remove duplicate definitions.
3139 * w32fns.c: Include w32common.h; include w32heap.h only in
3142 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3143 Use `report_file_error' instead of `error' in order to better
3144 inform users of what went wrong. Increase NTGUI_UNICODE file
3145 dialog box file name length to 32k, the maximum allowed by the NT
3148 * w32common.h: New file.
3149 (ROUND_UP, ROUND_DOWN, get_page_size)
3150 (get_allocation_unit, get_processor_type, get_w32_major_version)
3151 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3152 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3153 (OS_NT, os_subtype, cache_system_info): Move here.
3155 * unexw32.c, unexcw.c: Include w32common.h.
3157 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3158 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3159 to call syms_of_w32select.
3161 * cygw32.h: Remove obsolete EXFUN declarations.
3163 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

3166 of w32inevt.o from SOME_MACHINE_OBJECTS.
3168 2012-10-08 Daniel Colascione <dancol@dancol.org>
3170 * image.c: Permanent fix for JPEG compilation issue --- limit
3171 jpeglib `boolean' redefinition to Cygwin builds.
3173 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3175 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3177 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3180 2012-10-08 Daniel Colascione <dancol@dancol.org>
3182 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3183 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3184 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3185 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3186 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3187 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3188 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3189 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3190 now a supported configuration.
3192 * Makefile.in: consolidate image variables into LIBIMAGE; add
3193 W32_OBJ and W32_LIBS. Compile new files.
3196 (_DebPrint) declare tracing facility for W32 debugging. We need
3197 to unify tracing later.
3199 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3200 unconditional use of W32 Unicode functions. Cygwin runs only on
3201 100% Unicode operating systems.
3203 * cygw32.c: New file. Define Cygwin-specific facilities.
3204 (Fcygwin_convert_path_to_windows)
3205 (Fcygwin_convert_path_from_windows): New user functions for
3206 accessing Cygwin path-munging routines.
3208 * cygw32.h: New file.
3209 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3210 UTF-16LE strings temporarily inside non-Lisp-visible string
3213 (w32_strerror): Just what it says on the tin.
3215 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3216 also run for Cygwin; both systems have the same problem with using
3217 GUI facilities in a forked child. Also call syms_of_cygw32,
3218 syms_of_w32select in correct places.
3220 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3221 needs fork-then-exec for daemon launching.
3223 * font.h: Include frame.h.
3225 * image.c: Use the image library cache machinery only when we're
3226 compiling for native WINDOWSNT; Cygwin can use shared libraries
3227 like any other Unixlike system.
3229 * keyboard.c: Clarify a comment regarding the input loop.
3231 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3232 functions directly instead of trying to detect at runtime that our
3233 host operating system supports them. We make this change for two
3234 reasons: Cygwin lacks support for the multibyte character
3235 conversion functions used by the legacy menu code, and Cygwin
3236 never needs to rely on non-Unicode APIs.
3238 * unexw32.c (hinst): Declare extern.
3240 * w32.c: Change header order;
3241 (w32_strerror): Move to w32fns.c because we need it for
3242 non-WINDOWSNT builds.
3244 * w32.h: Add #error macro to make sure we don't include w32.h for
3245 Cygwin builds. Remove w32select declarations.
3247 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3248 w32fns.c. w32console.c is WINDOWSNT-only.
3250 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3251 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3253 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3254 (w32_major_version, w32_minor_version, w32_build_number)
3255 (os_subtype, sound_type): Define here
3256 (w32_defined_color): Make color parameter const for consistency
3257 with other _defined_color functions.
3258 (w32_createwindow): Unconditionally call w32_init_class instead of
3259 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3260 through the code is complex and unnecessary because class
3261 registration is practically free.
3262 (w32_name_of_message): New EMACSDEBUG-only function.
3263 (Fset_message_beep): Move here
3264 (Fx_open_connection): Require that the display name for Windows be
3265 "w32" for consistency, emacsclient disambiguation, and maybe, one
3266 day, multi-window-system support.
3267 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3268 Cygwin files for W32 GUI facilities, since these clearly don't

3283 (w32_console_toggle_lock_key): Move to w32fns.c.
3285 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.

3294 descriptor the system used to tell us about pending thread
3297 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3298 that prevented compilation under non-WINDOWSNT systems.
3300 (w32_initialize): Open /dev/windows and assign it to
3301 w32_message_fd. Provide w32 feature.
3303 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.

3305 (prepend_msg, w32_message_fd): Declare globally.
3308 (keyboard_handle): Use only when WINDOWSNT.
3309 (notify_msg_ready): New function. Posts a message to the main
3310 thread's message queue under CYGWIN, which wakes up the main
3311 thread from select(2) by making the /dev/windows file descriptor
3312 ready. Under WINDOWSNT, it sets an event the same way the old
3315 (post, prepend_msg): Actually call notify_msg_ready instead of
3316 setting the input event directly.
3318 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3320 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3321 but it still has blocs in it, don't return it to the system,
3322 instead of aborting. (Bug#12402)
3324 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3326 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).

3359 Improve sys_siglist detection.
3360 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3361 defined as a macro, as is done in Solaris.
3362 (sys_siglist_entries): New macro.
3363 (save_strsignal): Use it.
3364 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3365 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3367 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3369 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3370 fullscreen/Fullscreen.
3372 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3373 tobar_height is new.
3375 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3376 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3377 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

3390 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3392 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3394 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3396 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3397 that time stamps of directories could also be changed.
3398 Don't request the too broad GENERIC_WRITE, only the more restrictive
3399 FILE_WRITE_ATTRIBUTES access rights.
3401 * fileio.c (Fset_file_times): Special-case ignoring errors for
3402 directories only on MSDOS, not on MS-Windows.
3404 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3406 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3408 2012-10-04 Eli Zaretskii <eliz@gnu.org>

3411 see whether CreateFile failed.
3413 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3415 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3416 to avoid similar races.
3417 * keyboard.c (pending_signals): Now bool, not int.
3419 Port timers to OpenBSD, plus check for timer failures.
3420 OpenBSD problem reported by Han Boetes.
3421 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3423 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3424 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3425 like OpenBSD, which has timer_settime but does not declare it.
3426 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3427 whether to use itimerspec-related primitives. All uses of
3428 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3430 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3432 * profiler.c (handle_profiler_signal): Fix a malloc race
3433 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3435 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3437 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3439 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3441 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3442 consistent with the change in return value of 'safe_strsignal'.
3444 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3446 Prefer plain 'static' to 'static inline' (Bug#12541).

3448 (bidi_set_sor_type, bidi_push_embedding_level)
3449 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

3454 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3455 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3456 Now 'static', not 'static inline'.
3458 Count overruns when profiling; change units to ns.
3459 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3460 Give extra weight to samples after overruns, to attempt to count
3461 the time more accurately.
3462 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3463 the underlying primitives nominally do ns.
3464 (Fprofiler_cpu_start): Document the change. Mention that
3465 the sampling intervals are only approximate.
3467 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3469 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3471 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3472 case for the special 0 coding-system.
3474 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3475 (Fmake_overlay): Remove redundant tests.
3476 (fix_start_end_in_overlays): Remove redundant recentering.
3478 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3480 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3481 Update dependencies.
3483 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3485 Fix a malloc race condition involving strsignal.
3486 A signal can arrive in the middle of a malloc, and Emacs's signal
3487 handler can invoke strsignal, which can invoke malloc, which is
3488 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3489 Fix it by altering the signal handler so that it does not invoke
3491 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3492 * process.c (status_message): Use const pointer, in case strsignal
3493 is #defined to safe_strsignal.
3494 * sysdep.c (sys_siglist, init_signals): Always define and
3495 initialize a substitute sys_siglist if the system does not define
3496 one, even if HAVE_STRSIGNAL.
3497 (safe_strsignal): Rename from strsignal. Always define,
3498 using sys_siglist. Return a const pointer.
3499 * syssignal.h (safe_strsignal): New decl.
3500 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3502 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3504 * w32proc.c (timer_loop): Fix code that waits for timer
3505 expiration, to avoid high CPU usage.
3507 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3509 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3510 (sweep_weak_table): Remove redundant prototypes.
3512 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3514 * emacs.c: Move the inclusion of TERM_HEADER after including
3515 windows.h on WINDOWSNT. This avoids compilation problems with
3518 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3520 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3521 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3522 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3523 as the previous version used 'void *'.
3525 * ralloc.c (ROUNDUP): Fix last change.
3526 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3529 * w32proc.c <disable_itimers>: New static flag.
3530 (init_timers): Initialize it to zero, after creating the critical
3531 sections used by the timer threads.
3532 (term_timers): Set to 1 before deleting the critical sections.
3533 (getitimer, setitimer): If disable_itimers is non-zero, return an
3534 error indication without doing anything. Reported by Fabrice
3535 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3536 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3538 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3541 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3542 term_ntproc after all the other bookkeeping, to get timers working
3543 as long as possible.
3545 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3547 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3548 Suggested by Juri Linkov in
3549 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3551 Prefer plain 'static' to 'static inline' (Bug#12541).
3552 With static functions, modern compilers inline pretty well by
3553 themselves; advice from programmers often hurts as much as it helps.
3554 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3555 this change shrinks the text size of the Emacs executable by 1.1%
3556 without affecting CPU significantly in my benchmark.
3557 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3637 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3639 Revert the FOLLOW-SYMLINKS change for file-attributes.
3640 Doing it right would require several changes to Tramp, and there's
3641 not enough time to get that tested before the freeze today.
3642 * dired.c (directory_files_internal, Ffile_attributes):
3645 * frame.c (x_report_frame_params): Port better to wider ints.
3646 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3647 or that pointers can be printed in 15 decimal digits.
3648 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

3829 Suggested by Eli Zaretskii in
3830 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
3832 2012-09-30 Eli Zaretskii <eliz@gnu.org>
3834 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
3835 HAVE_TIMER_SETTIME is defined.
3837 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
3839 Profiler improvements: more-accurate timers, overflow checks.
3840 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
3841 signal.h, setjmp.h. Include systime.h instead.
3842 (saturated_add): New function.

3849 All uses changed to store the new value.
3850 (handle_profiler_signal): Rename from sigprof_handler_1,
3851 for consistency with other handlers. Do not check whether
3852 cpu_log is a hash-table if garbage collecting, since it
3853 doesn't matter in that case.

3855 for consistency with other handlers.
3856 (setup_cpu_timer): New function, with much of what used to be in
3857 Fprofiler_cpu_start. Check for out-of-range argument.
3858 Prefer timer_settime if available, and prefer
3859 thread cputime clocks, then process cputime clocks, then
3860 monotonic clocks, to the old realtime clock. Use make_timeval
3861 to round more-correctly when falling back to setitimer.
3862 (Fprofiler_cpu_start): Use it.
3863 (Fprofiler_cpu_stop): Prefer timer_settime if available.
3864 Don't assume that passing NULL as the 2nd argument of setitimer

3867 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
3868 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
3869 non-fatal signal handlers. Ignore SIGPROF on startup.
3870 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
3871 in profiler.c, since sysdep.c now uses it.
3873 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

3929 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
3930 Since this stuff is now private to charset.c, there's no need for
3931 a public macro and no need to inline by hand.

4003 (sigaction): Rewrite to call sys_signal instead of duplicating its
4005 (sys_kill): Improve commentary.
4007 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4008 consistency with a signature of a signal handler. All callers
4010 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4011 install term_ntproc as a signal handler for SIGABRT, as that
4012 should be done by the dumped Emacs.
4014 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4016 * w32select.c (term_w32select): Protect against repeated
4017 invocation by setting clipboard_owner to NULL after calling

4154 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4155 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4156 wanted even on POSIXish hosts, and it doesn't work on Windows.
4158 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4160 * xterm.c (x_term_init): Call fixup_locale before and after calling
4161 gtk_init (Bug#12392).
4163 2012-09-23 Chong Yidong <cyd@gnu.org>
4165 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4166 Vdynamic_library_alist.
4168 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4169 (Fgnutls_available_p): Caller changed.
4171 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4172 (Flibxml_parse_xml_region): Likewise.
4174 * dispextern.h (struct image_type): Remove arg from init function.
4176 * image.c (Finit_image_library, lookup_image_type)
4177 (define_image_type): Remove now-unneeded second arg.
4178 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4179 (init_tiff_functions, init_gif_functions, init_svg_functions):
4180 Arglist and w32_delayed_load calling convention changed.
4181 (gs_type): Remove init_gs_functions; there is no such function.
4182 (valid_image_p, make_image): Fix caller to lookup_image_type.
4184 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4186 Simplify and avoid signal-handling races (Bug#12471).
4188 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4189 Avoid recursive loop if there's a fatal error in the function itself.
4190 * atimer.c (pending_atimers):
4191 * blockinput.h: Don't include "atimer.h"; no longer needed.
4192 (interrupt_input_pending): Remove. All uses removed.
4193 pending_signals now counts both atimers and ordinary interrupts.
4194 This is less racy than having three separate pending-signal flags.
4195 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4197 Rename from their upper-case counterparts BLOCK_INPUT,
4198 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4199 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4200 This makes it easier to access volatile variables more accurately.
4201 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4202 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4203 that's more reliable if the code is buggy and sets
4204 interrupt_input_blocked to a negative value. All uses changed.
4205 * atimer.c (deliver_alarm_signal):
4206 Remove. No need to deliver this to the parent; any thread can
4207 handle this signal now. All uses replaced by underlying handler.
4208 * atimer.c (turn_on_atimers):
4209 * dispnew.c (handle_window_change_signal):
4210 * emacs.c (handle_danger_signal):
4211 * keyboard.c (kbd_buffer_get_event):
4212 Don't reestablish signal handler; not needed with sigaction.
4213 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4215 Rework to avoid unnecessary accesses to volatile variables.
4216 (UNBLOCK_INPUT_TO): Now a function.
4217 (totally_unblock_input, unblock_input): New decls.
4218 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4219 (init_data): Remove. Necessary stuff now done in init_signal.
4220 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4221 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4222 (fatal_error_code): Remove; no longer needed.
4223 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4224 it doesn't always backtrace. All uses changed. No need to reset
4225 signal to default, since sigaction and/or die does that for us now.
4226 Use emacs_raise (FOO), not kill (getpid (), FOO).
4227 (main): Check more-accurately whether we're dumping.
4228 Move fatal-error setup to sysdep.c
4229 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4230 * gtkutil.c (xg_get_file_name, xg_get_font):
4231 Remove no-longer-needed signal-mask manipulation.
4232 * keyboard.c, process.c (POLL_FOR_INPUT):
4233 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4234 * keyboard.c (read_avail_input): Remove.
4235 All uses replaced by gobble_input.
4236 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4237 (kbd_buffer_store_event_hold, gobble_input):
4238 (record_asynch_buffer_change) [USABLE_SIGIO]:
4239 (store_user_signal_events):
4240 No need to mess with signal mask.
4241 (gobble_input): If blocking input and there are terminals, simply
4242 set pending_signals to 1 and return. All hooks changed to not
4243 worry about whether input is blocked.
4244 (process_pending_signals): Clear pending_signals before processing
4245 them, in case a signal comes in while we're processing.
4246 By convention callers now test pending_signals before calling us.
4247 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4248 New functions, to support changes to blockinput.h.
4249 (handle_input_available_signal): Now extern.
4250 (reinvoke_input_signal): Remove. All uses replaced by
4252 (quit_count): Now volatile, since a signal handler uses it.
4253 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4254 All callers changed. Block SIGINT only if not already blocked.
4255 Clear sigmask reliably, even if Fsignal returns, which it can.
4256 Omit unnecessary accesses to volatile var.
4257 (quit_throw_to_read_char): No need to restore sigmask.
4258 * keyboard.c (gobble_input, handle_user_signal):
4259 * process.c (wait_reading_process_output):
4260 Call signal-handling code rather than killing ourselves.
4261 * lisp.h: Include <float.h>, for...
4262 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4263 (pending_signals): Now volatile.
4264 (syms_of_data): Now const if IEEE floating point.
4265 (handle_input_available_signal) [USABLE_SIGIO]:
4266 (terminate_due_to_signal, record_child_status_change): New decls.
4267 * process.c (create_process): Avoid disaster if memory is exhausted
4268 while we're processing a vfork, by tightening the critical section
4270 (send_process_frame, process_sent_to, handle_pipe_signal)
4271 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4273 (send_process): No need for setjmp/longjmp any more, since the
4274 SIGPIPE stuff is now gone. Instead, report an error if errno
4276 (record_child_status_change): Now extern. PID and W are now args.
4277 Return void, not bool. All callers changed.
4278 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4279 Remove. All uses removed. This bug should be fixed now in a
4281 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4282 and record the child status change directly. This avoids the
4283 need to futz with the signal mask.
4284 (process_fatal_action): Move here from emacs.c.
4285 (emacs_sigaction_flags): New function, containing
4286 much of what used to be in emacs_sigaction_init.
4287 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4288 caught by emacs, to make races less likely.
4289 (deliver_process_signal): Rename from handle_on_main_thread.
4291 (BACKTRACE_LIMIT_MAX): Now at top level.
4292 (thread_backtrace_buffer, threadback_backtrace_pointers):
4294 (deliver_thread_signal, deliver_fatal_thread_signal):
4295 New functions, for more-accurate delivery of thread-specific signals.
4296 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4297 (deliver_arith_signal): Handle in this thread, not
4298 in the main thread, since it's triggered by this thread.
4299 (maybe_fatal_sig): New function.
4300 (init_signals): New arg DUMPING so that we can be more accurate
4301 about whether we're dumping. Caller changed.
4302 Treat thread-specific signals differently from process-general signals.
4303 Block all signals while handling fatal error; that's safer.
4304 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4306 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4307 Ignore SIGPIPE unless batch.
4308 (emacs_backtrace): Output backtrace for the appropriate thread,
4309 which is not necessarily the main thread.
4310 * syssignal.h: Include <stdbool.h>.
4311 (emacs_raise): New macro.
4312 * xterm.c (x_connection_signal): Remove; no longer needed
4313 now that we use sigaction.
4314 (x_connection_closed): No need to mess with sigmask now.
4315 (x_initialize): No need to reset SIGPIPE handler here, since
4316 init_signals does this for us now.
4318 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4320 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4321 background rect may be larger (Bug#12245).
4323 2012-09-23 Chong Yidong <cyd@gnu.org>
4325 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4327 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4329 * .gdbinit: Just stop at fatal_error_backtrace.
4330 See Stefan Monnier's request in
4331 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4332 Remove no-longer-used query of system type.
4334 2012-09-22 Chong Yidong <cyd@gnu.org>
4336 * search.c (Freplace_match): Doc fix (Bug#12325).
4338 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4340 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4341 (Fline_end_position): Doc fix.
4343 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4345 2012-09-22 Chong Yidong <cyd@gnu.org>
4347 * dispextern.h (struct image_type): Add new slot, storing a type
4348 initialization function.
4350 * image.c (define_image_type): Call the image initializer function
4351 if it is defined. Arguments and return value changed.
4352 (valid_image_p, make_image): Callers changed.
4353 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4354 (gif_type, imagemagick_type, svg_type, gs_type):
4355 Add initialization functions.
4356 (Finit_image_library): Call lookup_image_type.
4357 (CHECK_LIB_AVAILABLE): Macro deleted.
4358 (lookup_image_type): Call define_image_type here, rather than via
4359 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4360 (syms_of_image): Move define_image_type calls for xbm_type and
4361 pbm_type to lookup_image_type.
4363 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4365 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4366 'idle_timers' from here ...
4367 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4368 lists, to avoid infloops when the timer does something stupid,
4369 like reinvoke itself with the same or smaller time-out.
4372 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4374 * window.c (Fsplit_window_internal): Handle only Qt value of
4375 Vwindow_combination_limit separately.
4376 (Qtemp_buffer_resize): New symbol.
4377 (Vwindow_combination_limit): New default value.
4380 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4382 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4383 the new overlay string. (Bug#10159)
4385 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4387 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4388 or that fprintf is async-signal-safe. POSIX doesn't require
4391 2012-09-22 Chong Yidong <cyd@gnu.org>
4393 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4396 2012-09-22 Kenichi Handa <handa@gnu.org>
4398 * composite.c (composition_reseat_it): Handle the case that a
4399 grapheme cluster is not covered by a single font (Bug#12352).
4401 2012-09-21 Chong Yidong <cyd@gnu.org>
4403 * image.c (define_image_type): Avoid adding duplicate types to
4404 image_types (Bug#12463). Suggested by Jörg Walter.
4406 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4408 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4409 (print_load_command_name): Add case LC_DATA_IN_CODE.
4410 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4412 2012-09-21 Glenn Morris <rgm@gnu.org>
4414 * eval.c (Frun_hook_with_args_until_success)
4415 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4417 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4419 * fileio.c (Ffile_selinux_context): Only call freecon when
4420 lgetfilecon succeeded.
4421 (Fset_file_selinux_context): Likewise. (Bug#12444)
4423 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4425 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4426 reordering, locate the cursor by calling set_cursor_from_row; if
4427 that fails, clear the desired glyph matrix before returning a
4428 failure indication to the caller. Fixes leaving garbled display
4429 when fast scrolling with a down-key. (Bug#12403)
4430 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4431 scrolling through multibyte text.
4433 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4435 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4436 calling mark_vectorlike since that's the one that marks the window.
4437 (mark_discard_killed_buffers): Mark the final cdr.
4438 * window.h (struct window): Move prev/next_buffers to the
4439 non-standard fields.
4440 * window.c (make_window): Initialize prev/next_buffers manually.
4442 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4444 Omit unused arg EXPECTED from socket hooks.
4445 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4446 * nsterm.m (ns_term_init):
4447 * termhooks.h (struct terminal.read_socket_hook):
4448 * w32inevt.c (w32_console_read_socket):
4449 * w32term.c (w32_read_socket):
4450 * xterm.c (XTread_socket):
4451 Omit unused arg EXPECTED. All callers changed.
4452 (store_user_signal_events): Return void, not int, since callers no
4453 longer care about the return value. All uses changed.
4455 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4457 * w32gui.h (XParseGeometry): Do not declare.
4459 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4461 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4462 Ignore 'expected'. See Eli Zaretskii in
4463 <http://bugs.gnu.org/12471#8> (last line).
4465 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4466 (XParseGeometry): Now static. Substitute extremal values for
4467 values that are out of range.
4469 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4471 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4473 * nsfns.m (XParseGeometry): Remove.
4474 (Fx_create_frame): Call x_set_offset to correctly interpret
4475 top_pos in geometry.
4477 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4478 (Fx_parse_geometry): If there is a space in string, call
4479 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4481 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4483 * search.c (scan_buffer): Use character positions in calls to
4484 region_cache_forward and region_cache_backward, not byte
4485 positions. (Bug#12196)
4487 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4488 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4490 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4491 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4492 emacs_blocked_malloc, now deleted.
4494 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4496 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4497 The workaround was for improving performance on Solaris 2.4, but
4498 is getting in the way now. Emacs will still work if someone is
4499 still running Solaris 2.4 in a museum somewhere; Sun dropped
4500 support for Solaris 2.4 in 2003.
4501 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4502 * process.c (create_process) [HAVE_WORKING_VFORK]:
4503 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4504 since Emacs no longer uses vfork on that platform.
4506 2012-09-17 Glenn Morris <rgm@gnu.org>
4508 * emacs.c: Use COPYRIGHT.
4510 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4512 Remove configure's --without-sync-input option (Bug#12450).
4513 When auditing signal-handling in preparation for cleaning it up,
4514 I found that SYNC_INPUT has race conditions and would be a real
4515 pain to fix. Since it's an undocumented and deprecated
4516 configure-time option, now seems like a good time to remove it.
4517 Also see <http://bugs.gnu.org/11080#16>.
4518 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4519 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4520 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4521 (malloc_hysteresis):
4522 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4523 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4524 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4525 (dont_register_blocks, bytes_used_when_reconsidered)
4526 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4527 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4528 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4529 Remove. All uses removed.
4530 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4531 implementation, one that depends on whether the new macro
4532 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4534 * atimer.c (run_timers, handle_alarm_signal):
4535 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4536 (handle_async_input, process_pending_signals)
4537 (handle_input_available_signal, init_keyboard):
4538 * nsterm.m (ns_read_socket):
4539 * process.c (wait_reading_process_output):
4540 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4541 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4543 * xterm.c (XTread_socket):
4545 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4546 * eval.c (handling_signal): Remove. All uses removed.
4547 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4548 All uses replaced with the SYNC_INPUT version.
4549 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4551 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4554 * font.c (Ffont_shape_gstring): Remove unused local.
4556 2012-09-16 Glenn Morris <rgm@gnu.org>
4558 * Makefile.in (clean): No longer run nextstep's clean.
4560 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4562 (ns-app): Move here from ns.mk, and simplify.
4563 (clean): Simplify nextstep entry.
4564 * ns.mk: Remove file.
4566 2012-09-17 Kenichi Handa <handa@gnu.org>
4568 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4569 not covert the last few charactes.
4571 2012-09-16 Kenichi Handa <handa@gnu.org>
4573 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4574 here, but just check the validity of glyphs in the glyph-string.
4576 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4578 * window.c (Fwindow_parameter, Fset_window_parameter):
4579 Accept any window as argument (Bug#12452).
4581 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4583 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4584 to ns_term_init to avoid memory leak.
4586 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4587 explicit retain/release.
4588 (ns_term_init): Only allow one display. Initialize outerpool and
4591 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4593 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4594 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4595 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4596 the Microsoft problem in a different way, by altering ../nt/config.nt.
4598 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4613 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4614 by lisp.h. This completes removal of setjmp.h inclusion
4615 erroneously announced in the previous commit. (Bug#12446)
4617 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4620 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4621 not defined as a macro. The latter happens on MS-Windows.
4624 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4626 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4627 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4628 Some instances of '#include <setjmp.h>' removed, if the
4629 only reason for the instance was because "lisp.h" was included.
4630 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4631 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4632 and _longjmp with the new symbols. Emacs already uses _setjmp if
4633 available, so this change affects only POSIXish hosts that have
4634 sigsetjmp but not _setjmp, such as some versions of Solaris and
4635 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4636 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4637 (png_load_body) [HAVE_PNG]:
4638 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4639 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4640 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4641 since PNG requires jmp_buf. This is the only exception to the
4642 general rule that we now use sys_setjmp and sys_longjmp.
4643 This exception is OK since this code does not change the signal
4644 mask or longjmp out of a signal handler.
4646 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4648 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4649 Include "syssignal.h", for 'main_thread'.
4651 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4653 Avoid out-of-range marker position (Bug#12426).
4654 * insdel.c (replace_range, replace_range_2):
4655 Adjust markers before overlays, as suggested by comments.
4656 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4657 Remove redundant check before calling offset_intervals.
4659 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4661 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4662 current buffer (Bug#12387).
4664 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4666 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4668 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4670 Use a more backwards-compatible timer format (Bug#12430).
4671 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4672 vector element, not from the 4th, since PSECS is now at the end.
4673 (Fcurrent_idle_time): Doc fix.
4675 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4677 Function to mark objects and remove killed buffers at once.
4678 * alloc.c (discard_killed_buffers): Rename to ...
4679 (mark_discard_killed buffers) ... new name. Add marking
4680 of remaining objects. Fix comment. Adjust users.
4681 (mark_object): Do not touch frame buffer lists here.
4682 * frame.c (delete_frame): Reset frame buffer lists here.
4684 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4686 Better workaround for GNOME bug when --enable-gcc-warnings.
4687 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4688 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4689 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4691 Simplify SIGIO usage (Bug#12408).
4692 The code that dealt with SIGIO was crufty and confusing, e.g., it
4693 played tricks like "#undef SIGIO" but these tricks were not used
4694 consistently. Simplify mostly by not #undeffing standard symbols,
4695 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4696 or not as we please) rather than "defined SIGIO" (standard symbol
4697 that we probably shouldn't #undef).
4698 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4699 Modules that need it can include it.
4700 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4701 * dispextern.h (ignore_sigio): New decl.
4702 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4703 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4704 * emacs.c (shut_down_emacs):
4705 * keyboard.c (kbd_buffer_store_event_hold):
4706 Use ignore_sigio rather than invoking 'signal' directly.
4707 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4709 (FIONREAD, SIGIO): Do not #undef.
4710 (tty_read_avail_input): Use #error rather than a syntax error.
4711 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4712 for I_PIPE, used by SETUP_SLAVE_PTY.
4713 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4714 * sysdep.c (croak): Remove; no longer needed. This bit of
4715 temporary code, with Fred N. Fish's comment that it's temporary,
4716 has been in Emacs since at least 1992!
4717 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4718 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4719 * syssignal.h (croak): Remove decl.
4720 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4721 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4722 now that we're termios-only.
4723 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4724 * term.c (dissociate_if_controlling_tty): Use #error rather than
4727 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4728 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4729 to work around GNOME bug 683906.
4730 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4731 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4732 This works around GCC bug 54561.
4734 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4736 More fixes for 'volatile' and setjmp/longjmp.
4737 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4738 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4739 (png_load_body) [HAVE_PNG]:
4740 (jpeg_load_body) [HAVE_JPEG]:
4741 New function, with most of the old parent function's body.
4742 (png_load) [HAVE_PNG]:
4743 (jpeg_load) [HAVE_JPEG]:
4744 Invoke the new function, to avoid longjmp munging our locals.
4745 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4746 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4747 longjmp is passed 2, as the C standard doesn't guarantee this.
4748 Instead, store the failure code into mgr->failure_code.
4750 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4752 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4753 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4754 (syms_of_keyboard): Remove support for unread-command-char.
4756 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4758 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4759 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4760 violation. (Bug#12426)
4762 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4764 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4766 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4768 * eval.c: Add `inhibit-debugger'.
4769 (Qinhibit_debugger): New symbol.
4770 (call_debugger): Bind it instead of Qdebug_on_error.
4771 (maybe_call_debugger): Test Vinhibit_debugger.
4772 (syms_of_eval): Define inhibit-debugger.
4773 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4774 (syms_of_xdisp): Remove inhibit-debug-on-message.
4776 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4778 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4779 If a nonvolatile local variable is written before a _longjmp to
4780 the frame containing the variable, and is read after the _longjmp,
4781 the value read is indeterminate. Some local variables of type
4782 'struct handler' and 'struct catchtag' are used in this way, so
4783 mark each of their slots as volatile if the slot can be set before
4784 _longjmp and read afterwards.
4785 * lisp.h (struct handler): var and chosen_clause are now volatile.
4786 (struct catchtag): val, next, and pdlcount are now volatile.
4788 * bidi.c (bidi_push_it, bidi_pop_it):
4789 * fns.c (copy_hash_table):
4790 * image.c (define_image_type):
4791 * keyboard.c (kbd_buffer_store_event_hold):
4792 * process.c (Fprocess_send_eof):
4793 * xfaces.c (x_create_gc) [HAVE_NS]:
4794 * xgselect.c (xg_select):
4795 Prefer assignment to memcpy when either will do.
4797 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4798 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4799 time an item is removed. No need to mark this function 'inline';
4800 the compiler knows better than we do.
4802 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4804 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4805 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4806 to change_frame_size (Bug#12388).
4807 (windowDidResize:): Pass YES to updateFrameSize.
4809 * nsterm.h: Add delay parameter to updateFrameSize.
4811 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4813 Discard killed buffers from deleted window and frame objects.
4814 This reduces an amount of references to killed buffers and
4815 helps GC to reclaim them faster.
4816 * alloc.c (discard_killed_buffers): New function.
4817 (mark_object): Use it for deleted windows and frames.
4818 (mark_object): If symbol's value is set up for a killed buffer
4819 or deleted frame, restore its global binding.
4820 * data.c (swap_in_global_binding): Add GC notice.
4821 (swap_in_symval_forwarding): Use convenient set_blv_where.
4822 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4823 * window.h: ... to here.
4825 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4827 Convenient macro to check whether the buffer is live.
4828 * buffer.h (BUFFER_LIVE_P): New macro.
4829 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4830 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4832 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4834 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4835 composition cases (Bug#12364).
4837 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4838 overhang of succeeding glyphs overlapping box cursor.
4840 * w32term.c (x_draw_glyph_string): Likewise.
4842 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4844 Simplify, document, and port floating-point (Bug#12381).
4845 The porting part of this patch fixes bugs on non-IEEE platforms
4846 with frexp, ldexp, logb.
4847 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4849 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4850 support, by removing commented-out code and briefly listing the
4851 C89 functions excluded. The commented-out stuff was confusing
4852 maintenance, e.g., we thought we needed cbrt but it was commented out.
4853 (logb): Remove decl; no longer needed.
4854 (isfinite): New macro, if not already supplied.
4855 (isnan): Don't replace any existing macro.
4856 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4857 are present on all C89 platforms.
4858 (Ffrexp): Do not special-case zero, as frexp does the right thing
4860 (Flogb): Do not use logb, as it doesn't have the desired meaning
4861 on hosts that use non-base-2 floating point. Instead, stick with
4862 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4863 frexp, to avoid getting an unspecified result.
4865 * xdisp.c (Qinhibit_debug_on_message): Now static.
4867 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4869 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4870 NSBezierPath (Bug#12131).
4872 2012-09-10 Chong Yidong <cyd@gnu.org>
4874 * fns.c (Fdelq, Fdelete): Doc fix.
4876 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4878 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4879 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4881 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4883 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4884 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4887 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4889 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4890 left fringe if the window has a left margin. This avoids leaving
4891 traces of the cursor because its leftmost pixel is not drawn over.
4893 * dispnew.c (update_window_line): When the left margin area of a
4894 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4895 that screen line. (Bug#12277)
4897 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4899 Assume C89 or later for math functions (Bug#12381).
4900 This simplifies the code, and makes it a bit smaller and faster,
4901 and (most important) makes it easier to clean up signal handling
4902 since we can stop worring about floating-point exceptions in
4903 library code. That was a problem before C89, but the problem
4904 went away many years ago on all practical Emacs targets.
4905 * data.c, image.c, lread.c, print.c:
4906 Don't include <math.h>; no longer needed.
4907 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4908 might be autoconfigured, as that never happens.
4910 * doprnt.c (DBL_MAX_10_EXP):
4911 * print.c (DBL_DIG):
4912 Remove. C89 or later always defines these.
4913 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4914 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4915 (arith_error, domain_error, domain_error2):
4916 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4917 no longer needed -- we simply return what C returns. All uses removed.
4918 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4920 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4921 Remove. All uses expanded, as these macros are no longer used
4922 more than once and are now more trouble than they're worth.
4923 (Ftan): Use tan, not sin / cos.
4924 (Flogb): Assume C89 frexp.
4925 (fmod_float): Assume C89 fmod.
4926 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4927 (init_floatfns): Remove. All uses removed.
4929 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4931 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4932 compositeToPoint for OSX < 10.6 (Bug#12390).
4934 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4936 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4937 This produces more-accurate results.
4939 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4941 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4942 changes (Bug#12088).
4944 2012-09-08 Chong Yidong <cyd@gnu.org>
4946 * syntax.c (Fstring_to_syntax): Doc fix.
4948 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4950 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4951 in the internal border.
4952 (x_set_window_size): Remove static variables and their usage.
4953 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4954 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4955 Remove fringe/internal border adjustment (Bug#11052).
4956 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4957 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4958 (ns_fix_rect_ibw): Remove.
4959 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4960 (ns_dumpglyphs_box_or_relief): Ditto.
4961 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4963 (ns_dumpglyphs_image): Ditto.
4964 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4966 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4967 their usage. Add fringe_extended_p and its use as in other terms.
4968 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4969 scroll bar was removed.
4970 (updateFrameSize): New function.
4971 (windowDidResize): Move code to updateFrameSize and call it.
4973 * nsterm.h (EmacsView): Add updateFrameSize.
4975 2012-09-07 Chong Yidong <cyd@gnu.org>
4977 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4979 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4981 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4983 More signal-handler cleanup (Bug#12327).
4984 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4985 Problem introduced when merging patches. Noted by Eli Zaretskii in
4986 <http://bugs.gnu.org/12327#67>.
4987 * floatfns.c: Comment fix.
4988 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4989 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4990 and anyway the declaration is harmless even if SIGDANGER is not defined.
4991 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4992 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4993 source files not surprisingly expected syssignal.h to define, or
4994 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4995 Include <sys/ioctl.h>, for FIONREAD.
4996 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4997 This eliminates a problem whereby other files mysteriously had
4998 to include "syssignal.h" before including "systty.h" if they
4999 wanted to use "#ifdef SIGIO".
5001 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5003 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5005 * w32.c (sigemptyset): Empty the set.
5006 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5008 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5010 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5012 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5013 (mark_object): Likewise for frame objects.
5015 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5017 * syssignal.h (handle_on_main_thread): Always declare,
5018 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5019 This ports to platforms without HAVE_PTHREAD.
5021 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5023 Signal-handler cleanup (Bug#12327).
5024 Emacs's signal handlers were written in the old 4.2BSD style with
5025 sigblock and sigmask and so forth, and this led to some
5026 inefficiencies and confusion. Rewrite these to use
5027 pthread_sigmask etc. without copying signal sets around. Also,
5028 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5029 'signal', and instead use functions that do not attempt to take
5030 over the system name space. This patch causes Emacs's text
5031 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5032 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5033 Do not include <signal.h> or "syssignal.h", as these
5034 modules do not use signals.
5035 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5036 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5037 Do not include <signal.h>, as "syssignal.h" does that for us now.
5038 * atimer.c (sigmask_atimers): New function.
5039 (block_atimers, unblock_atimers): New functions,
5040 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5042 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5043 no longer needed here.
5044 * emacs.c (main): Inspect existing signal handler with sigaction,
5045 so that there's no need to block and unblock SIGHUP.
5046 * sysdep.c (struct save_signal): New member 'action', replacing
5047 old member 'handler'.
5048 (save_signal_handlers, restore_signal_handlers):
5049 Use sigaction instead of 'signal' to save and restore.
5050 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5051 New function. All users of 'signal' modified to use set_sighandler
5052 if they're writeonly, and to use sys_signal if they're read+write.
5053 (emacs_sigaction_init, forwarded_signal): New functions.
5054 (sys_signal): Remove. All uses replaced by calls to sigaction
5055 and emacs_sigaction_init, or by direct calls to 'signal'.
5056 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5057 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5058 all uses replaced by pthread_sigmask etc. calls.
5059 * syssignal.h: Include <signal.h>.
5060 (emacs_sigaction_init, forwarded_signal): New decls.
5061 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5062 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5063 (sigmask, sys_sigmask): Remove; no longer needed.
5064 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5065 (sigblock, sigunblock, sigfree):
5066 (sigsetmask) [!defined sigsetmask]:
5067 Remove. All uses replaced by pthread_sigmask.
5068 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5069 no longer need to be replaced, and its typical old uses
5070 are now done via emacs_sigaction_init and sigaction.
5071 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5072 (sys_sigdel): Remove; unused.
5073 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5075 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5077 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5078 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5080 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5082 Explicitly mark buffer_defaults and buffer_local_symbols.
5083 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5084 mark_local_symbols here.
5085 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5086 since special buffers aren't marked here any more.
5087 (allocate_buffer): Chain new buffer with all_buffers here...
5088 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5090 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5091 (syms_of_buffer): Remove staticpro of the above.
5092 (init_buffer_once): Set names for buffer_defaults and

5095 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5097 Use bool for booleans in font-related modules.
5098 * font.c (font_intern_prop, font_style_to_value)
5099 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5100 (generate_otf_features, font_check_otf_features, font_check_otf)
5101 (font_match_p, font_list_entities, font_at):
5102 * fontset.c (fontset_id_valid_p, reorder_font_vector
5103 (fontset_find_font, Fset_fontset_font)
5104 (face_suitable_for_char_p) [0]:
5105 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5106 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5107 (m17n_flt_initialized, ftfont_shape_by_flt):
5108 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5109 * nsfont.m (nsfont_draw):
5110 * w32font.c (w32font_draw):
5111 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5112 Use bool for booleans.
5113 * font.h: Adjust to above API changes.
5114 (struct font, struct font_driver, struct font_driver_list):
5115 Use bool for booleans.
5116 (struct font): Remove useless member encoding_type.
5118 * fontset.c, xftfont.c: Omit unnecessary static decls.
5120 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5122 * alloc.c (mark_object): Revert window marking code
5123 since it's unsafe for the Fset_window_configuration.
5125 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5127 Fix race conditions with signal handlers and errno (Bug#12327).
5128 Be more systematic about preserving errno whenever a signal
5129 handler returns, even if it's not in the main thread. Do this by
5130 renaming signal handlers to distinguish between signal delivery
5131 and signal handling. All uses changed.
5132 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5133 * data.c (deliver_arith_signal): Rename from arith_error.
5134 * dispnew.c (deliver_window_change_signal): Rename from
5135 window_change_signal.
5136 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5137 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5138 * keyboard.c (deliver_input_available_signal): Rename from
5139 input_available_signal.
5140 (deliver_user_signal): Rename from handle_user_signal.
5141 (deliver_interrupt_signal): Rename from interrupt_signal.
5142 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5143 (deliver_child_signal): Rename from sigchld_handler.
5144 * atimer.c (handle_alarm_signal):
5145 * data.c (handle_arith_signal):
5146 * dispnew.c (handle_window_change_signal):
5147 * emacs.c (handle_fatal_signal, handle_danger_signal):
5148 * keyboard.c (handle_input_available_signal):
5149 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5150 * process.c (handle_pipe_signal, handle_child_signal):
5151 New functions, with the actual signal-handling code taken from the
5152 original respective signal handlers, sans the sporadic attempts to
5153 preserve errno, since that's now done by handle_on_main_thread.
5154 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5155 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5156 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5158 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5159 Move initialization of main_thread to sysdep.c's init_signals.
5160 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5161 our usage, and simplifies the mainline code.
5162 (record_child_status_change): New static function, as a helper
5163 for handle_child_signal, and with most of the old child handler's
5165 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5166 (handle_child_signal): Use the above.
5167 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5168 Moved here from emacs.c.
5169 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5170 code moved here from emacs.c's main function.
5171 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5172 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5173 This lets callers save and restore errno properly.
5175 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5177 Remove redundant or unused things here and there.
5178 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5179 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5180 * editfns.c (Fcompare_buffer_substrings): Likewise.
5181 * frame.h (struct terminal, struct font_driver_list):
5182 Remove redundant declarations.
5183 * window.h (Qleft, Qright): Likewise.
5185 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5187 Do not mark objects from deleted buffers, windows and frames.
5188 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5189 (mark_object): Likewise for windows and frames.
5191 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5193 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5194 buffer_defaults and buffer_local_symbols as valid objects.
5195 Return special value to denote them.
5197 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5199 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5200 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5201 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5202 (file_name_absolute_p, Fsubstitute_in_file_name):
5203 (check_executable, check_writable, Ffile_accessible_directory_p)
5204 (Fset_file_selinux_context, Fdefault_file_modes)
5205 (Finsert_file_contents, choose_write_coding_system)
5206 (Fwrite_region, build_annotations, a_write, e_write)
5208 * filelock.c (boot_time_initialized, get_boot_time)
5209 (get_boot_time_1, lock_file_1, within_one_second):
5210 * floatfns.c (in_float):
5211 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5212 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5213 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5214 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5215 * window.c (compare_window_configurations):
5216 Use bool for booleans.
5217 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5218 (Fdefault_file_modes): Now mode_t, not int, for modes.
5219 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5220 (internal_delete_file): Now returns void, not a (boolean) int,
5221 since nobody was looking at the return value.
5222 * lisp.h, window.h: Adjust to above API changes.
5224 * xdisp.c (set_message): Simplify and reindent last change.
5226 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5228 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5230 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5232 * eval.c (call_debugger): Make the function non-static so that we
5233 can call it from set_message.
5235 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5236 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5238 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5240 Give more-useful info on a fatal error (Bug#12328).
5241 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5242 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5243 of doing the work ourselves.
5244 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5245 do most of the work.
5246 (fatal_error_backtrace): New function, taken from the guts
5247 of the old fatal_error_signal, but with a new option to output
5249 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5250 info about the signal than just its number.
5251 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5252 * sysdep.c: Include <execinfo.h>
5253 (emacs_backtrace): New function, taken partly from the previous
5254 code of the 'die' function.
5255 (emacs_abort): Call fatal_error_backtrace rather than abort.
5257 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5259 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5260 eager (load-time) macro-expansion.
5261 * lisp.mk (lisp): Add macroexp.
5263 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5265 Simplify redefinition of 'abort' (Bug#12316).
5266 Do not try to redefine the 'abort' function. Instead, redo
5267 the code so that it calls 'emacs_abort' rather than 'abort'.
5268 This removes the need for the NO_ABORT configure-time macro
5269 and makes it easier to change the abort code to do a backtrace.
5270 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5271 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5272 Remove; sysdep.c's emacs_abort now takes its place.
5273 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5274 'abort' changed to use 'emacs_abort'.
5275 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5276 (abort) [!defined abort]: Rename to ...
5277 (emacs_abort): ... new name.
5278 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5279 the place of the old 'abort' in emacs.c.
5280 * w32.c, w32fns.c (abort): Do not #undef.
5281 * w32.c (emacs_abort): Rename from w32_abort.
5283 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5285 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5286 offsets[j].dv, since the y axis of the screen coordinates points
5287 down, while the y axis of the font definition coordinates points
5288 up. This fixes display of Arabic diacritics such as KASRA and
5289 KASRATAN. (Bug#11860)
5291 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5293 Be more systematic about _setjmp vs setjmp.
5294 * alloc.c (test_setjmp, mark_stack):
5295 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5296 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5297 (png_load, my_error_exit, jpeg_load):
5298 * process.c (send_process_trap, send_process):
5299 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5300 The underscored versions are up to 30x faster on some hosts.
5301 Formerly, the code used setjmp+longjmp sometimes and
5302 _setjmp+_longjmp at other times, with no particular reason to
5303 prefer setjmp+longjmp.
5305 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5307 Fix minor problem found by static checking.
5308 * buffer.c (Fdelete_all_overlays): Return nil.
5310 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5312 * buffer.c (Fdelete_all_overlays): New function.
5314 2012-09-03 Chong Yidong <cyd@gnu.org>
5316 * gtkutil.c: Add extern decl for Qxft.
5318 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5320 * emacs.c, eval.c: Use bool for boolean.
5321 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5322 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5323 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5324 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
5325 (main, decode_env_path, Fdaemon_initialized):
5326 * eval.c (call_debugger, Finteractive_p, interactive_p):
5327 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
5328 (maybe_call_debugger, Fbacktrace):
5329 * process.c (read_process_output, exec_sentinel):
5330 Use bool for booleans.
5331 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5332 All callers changed.
5333 * eval.c (interactive_p): Omit always-true boolean argument
5334 EXCLUDE_SUBRS_P. All callers changed.
5335 * dispextern.h, lisp.h: Reflect above API changes.
5336 * firstfile.c (dummy): Use the address of 'main', whose signature
5337 won't change, instead of the address of 'initialize', whose
5338 signature just changed from int to bool.
5339 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5340 * msdos.c (fatal_error_in_progress): ... from here.
5341 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5343 (redisplay_internal, unwind_redisplay): Simply clear
5344 REDISPLAYING_P when unwinding, instead of saving its previous,
5345 always-false value and then restoring it.
5347 Clean up some extern decls.
5348 Mostly, this hoists extern decls out of .c files and into .h files.
5349 That way, we're more likely to catch errors if the interfaces change.
5350 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5351 declare xg_mark_data.
5352 * dispextern.h (x_frame_parm_handlers):
5354 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5355 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
5356 (Qultra_bold, Qoblique, Qitalic):
5357 Move extern decl here from .c file.
5358 * alloc.c (xg_mark_data) [USE_GTK]:
5360 * eval.c (Qlexical_binding):
5361 * fns.c (time) [!HAVE_UNISTD_H]:

5367 * process.c (QCfamily, QCfilter):
5368 * widget.c (free_frame_faces):
5369 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
5370 * xfont.c (x_clear_errors):
5371 * xterm.c (x_frame_parm_handlers):
5372 Remove now-redundant extern decls.
5373 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5374 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5376 * xfaces.c: Remove unnecessary static decls.
5377 * xterm.c (updating_frame): Remove decl of nonexistent object.
5379 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5380 when building globals.h, as the objects that are not built on
5381 this host are not needed to compile C files on this host.
5383 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5385 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
5387 * frame.h: Add missing prototype for x_wm_set_size_hint.
5389 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

5393 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
5394 (Fsubstitute_command_keys):

5399 (make_buffer_string, make_buffer_string_both)
5400 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

5413 * keyboard.c (decode_timer):
5414 Use bool for boolean.
5415 * intervals.h, lisp.h, systime.h: Reflect above API changes.
5416 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
5418 2012-09-02 Chong Yidong <cyd@gnu.org>
5420 * keymap.c (push_key_description): Print M-TAB as C-M-i
5423 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5425 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
5426 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
5427 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

5431 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
5433 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5435 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5436 more than one grapheme cluster passed to the shaper: compute the
5437 offset adjustment values separately for each cluster. (Bug#11860)
5439 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5440 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5441 about implicit conversions from integer to pointer.
5443 2012-09-01 Daniel Colascione <dancol@dancol.org>
5445 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5446 system used too early.
5448 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
5450 Better seed support for (random).
5451 * emacs.c (main): Call init_random.
5452 * fns.c (Frandom): Set the seed from a string argument, if given.
5453 Remove long-obsolete Gentzel cruft.
5454 * lisp.h, sysdep.c (seed_random): Now takes address and size, not long.
5455 (init_random): New function.
5457 2012-09-01 Daniel Colascione <dancol@dancol.org>
5459 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
5460 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
5461 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
5462 x_wm_set_size_hint, x_query_colors, x_real_positions,
5463 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
5464 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,

5555 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
5556 does not become zero (Bug#12234).

5586 (timeout_handler:): Set timer_fired to YES.
5587 (runDialogAt:): Set timer_fired to NO.
5588 Handle click on close button as quit.
5590 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5591 Add window_closed and button_values. Add void as return value for
5592 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5593 Add process_dialog as new member.
5595 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5597 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

5733 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5734 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5735 not a boolean 'int', since callers never look at the return value.

5738 (emacs_mule_string_char): Remove unused extern decls.
5739 (struct iso_2022_spec, struct coding_system):

5747 Fix spare memory change (Bug#12286).
5748 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5749 (valid_lisp_object_p): Likewise.
5751 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5753 * window.c (Fset_window_configuration): Record any window's old
5754 buffer if it's replaced (see Bug#8789). If the new current
5755 buffer doesn't appear in the selected window, go to its old
5758 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5760 Special MEM_TYPE_SPARE to denote reserved memory.
5761 * alloc.c (enum mem_type): New memory type.
5762 (refill_memory_reserve): Use new type for spare memory.
5763 This prevents live_cons_p and live_string_p from incorrect

5766 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5769 * Makefile.in (.PHONY): versioclean -> versionclean.

5773 * window.c (Qwindow_valid_p, decode_valid_window):
5774 Now static, not extern.
5775 * data.c (Qinterval): Remove; unused.

5792 (map_sub_char_table):
5793 Use bool for boolean.

5795 always 0. All callers changed.
5796 * character.h, charset.h: Adjust to match previous changes.
5797 * character.h (char_printable_p): Remove decl of nonexistent function.
5798 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5799 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5800 are all boolean, so make them single-bit bitfields.
5802 * lisp.h (ASET): Remove attempt to detect side effects.
5803 It was meant to be temporary and it often doesn't work,
5804 because when IDX has side effects the behavior of IDX==IDX
5805 is undefined. See Stefan Monnier in
5806 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5808 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5810 * lisp.h (functionp): New function (extracted from Ffunctionp).
5811 (FUNCTIONP): Use it.
5812 * eval.c (Ffunctionp): Use it.
5814 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5816 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5817 as that's faster and simpler than static storage. Don't bother
5818 with the g_main_context_query overhead if g_main_context_pending
5819 says no events are pending.
5820 (gfds, gfds_size): Remove these static vars.
5821 (xgselect_initialize): Remove; no longer needed.
5822 All uses and decls removed.
5824 * emacs.c (fatal_error_signal_hook): Remove.
5825 All uses removed. This leftover from old code was always 0.
5827 * casefiddle.c, casetab.c, category.c: Use bool for boolean.

5852 Use bool for booleans, instead of int.
5853 * lisp.h, process.h: Adjust prototypes to match above changes.
5854 * callint.c (Fcall_interactively): Don't assume the mark's
5855 offset fits in 'int'.

5867 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5868 Use bool for booleans, instead of int.
5869 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5870 since the 1-or-0 return value is always ignored anyway.
5871 (mmap_initialized_p):
5872 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5873 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5875 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5877 * bidi.c: Use bool for boolean.
5878 This is a bit more readable, and makes the text segment of bidi.o
5879 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5880 Presumably it's faster too.

5914 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5916 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5917 Otherwise, the compiler complains about (A?B:C) where B is void
5918 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5919 (fontset_add): Return void, for FONTSET_ADD.
5921 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>

5925 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5926 (dont_register_blocks) [GC_MALLOC_CHECK]:
5927 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5928 (check_string_bytes, make_specified_string, memory_full)
5929 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5930 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5931 (mark_stack, valid_pointer_p, make_pure_string)
5932 (Fgarbage_collect, survives_gc_p, gc_sweep):
5933 Use bool for booleans, instead of int.
5934 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5935 Remove unused local.
5936 * alloc.c (PURE_POINTER_P):
5937 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5938 * editfns.c (Fformat):
5939 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5941 * fns.c (sweep_weak_table):
5942 * lisp.h (suppress_checking, push_message, survives_gc_p)
5943 (make_pure_string, gc_in_progress, abort_on_gc):
5944 * lread.c (readchar, read1):
5945 * print.c (Fprin1_to_string):
5946 * xdisp.c (push_message):
5947 Use bool for booleans affected directly or indirectly by
5950 Make recently-introduced setters macros.
5951 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5952 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5953 (set_fontset_default, set_fontset_fallback): Rename from their
5954 upper-case counterparts, and make them functions rather than macros.
5955 This is more consistent with the other recently-introduced setters.
5956 These don't need to be inline, since they're local.
5958 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5960 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in

5963 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5965 * lisp.h (vcopy): Use memcpy rather than our own loop.
5966 This fixes a performance regression introduced by the recent
5967 addition of vcopy. This means 'vcopy' will need to be modified
5968 for a copying collector, but that's OK. Also, tighten the
5969 checking in the assertion.
5971 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5973 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5974 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5975 non-base glyph for the width of the base character, according to
5976 what x_draw_composite_glyph_string_foreground expects.
5977 Generate WADJUST value according to composition_gstring_width's
5978 expectations, to produce correct width of the composed character.
5979 Reverse the sign of the DU offset produced by ScriptPlace.
5981 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5983 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.

5987 Avoid direct writes to contents member of struct Lisp_Vector.
5988 * lisp.h (vcopy): New function to copy data into vector.
5989 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5990 * fns.c (Ffillarray): Use ASET.
5991 * keyboard.c (timer_check_2): Use AREF and ASET.
5992 (append_tool_bar_item, Frecent_keys): Use vcopy.

6004 buffer to the specified position.
6006 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>

6009 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6010 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6011 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6014 2012-08-20 Glenn Morris <rgm@gnu.org>
6016 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6017 Don't assume that `ln -f' works.
6019 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6021 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6022 and later about non-assignments with no effect. See discussion at
6023 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6026 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6028 Inline setter functions for Lisp_Objects slots of struct specbinding.
6029 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6032 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6034 * window.c (select_window): Always make selected window's buffer
6037 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6039 Use AREF and ASET for docstrings of category tables.
6040 * category.h (CATEGORY_DOCSTRING): Use AREF.
6041 (SET_CATEGORY_DOCSTRING): Use ASET.
6042 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6044 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6046 Inline setter functions for hash table members.
6047 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6048 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6049 (set_hash_key_and_value, set_hash_index, set_hash_next)
6050 (set_hash_hash): New functions.
6051 * charset.c, fns.c: Adjust users.
6053 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6055 Inline getter and setter functions for per-buffer values.
6056 * buffer.h (per_buffer_default, set_per_buffer_default)
6057 (per_buffer_value, set_per_buffer_value): New functions.

6059 * buffer.c, data.c: Adjust users.
6061 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6063 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6065 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6067 Rely on <config.h> + <unistd.h> to declare 'environ',
6068 as gnulib does this if the system doesn't.
6069 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6070 Remove declaration. MS-Windows declares it on stdlib.h which is
6071 included by conf_post.h.
6072 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6073 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6074 * vm-limit.c: Include <unistd.h>, for 'environ'.
6076 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6077 (start_of_data): Remove decl; mem-limits.h provides it.
6079 * xdisp.c (handle_invisible_prop): Make it a bit faster
6080 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6082 2012-08-19 Chong Yidong <cyd@gnu.org>
6084 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6087 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>

6092 * data.c (set_internal): Don't use set_blv_found.
6093 (Fkill_local_variable): Likewise.
6095 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6097 * nsfont.m (ns_ascii_average_width): Ensure the string
6098 ascii_printable is initialized with a null-terminated character
6099 array. Otherwise, it can contain undesired extra characters.
6101 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6103 port new setting code to Sun C 5.8 2005/10/13
6104 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6105 Return void, not Lisp_Object. Otherwise, the compiler
6106 complains about (A?B:C) where B is void and C is Lisp_Object
6107 when compiling CHAR_TABLE_SET, due to the recent change to
6108 the API of sub_char_table_set_contents.
6110 2012-08-18 Chong Yidong <cyd@gnu.org>
6112 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE

6268 The old version was confusing because it used the same name
6269 'parent' for two different things.

6282 font spec, make the font's attributes take precedence over
6283 directly-specified attributes.
6284 (merge_face_ref): Recognize :font.
6286 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

6333 Use C-locale tests instead of locale-specific tests for character
6334 types, since we want the ASCII interpretation here, not the
6335 interpretation suitable for whatever happens to be the current locale.

6940 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6941 * w32.c (init_environment): Change the default values of many
6942 environment variables in dflt_envvars[] to NULL, to avoid pushing
6943 them into environment when they were not already defined.
6944 Remove the code that deletes site-lisp subdirectories from the default
6945 value of EMACSLOADPATH, as it is no longer needed.
6946 (check_windows_init_file): Now external, not static.
6947 Use Vload_path as is, without adding anything, as this function is now
6948 called when Vload_path is already set up.
6950 * w32.h (check_windows_init_file): Add prototype.
6952 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6958 any, in the DEFALT argument into the root of the Emacs build or
6959 installation tree, as appropriate.
6961 * callproc.c (init_callproc_1): Call decode_env_path instead of
6962 doing its equivalent by hand.
6963 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
6964 the code that sets Vexec_path run on MS-Windows.
6966 * lread.c (init_lread): Add comments to #ifdef's.
6968 * msdos.c (dos_set_window_size, IT_update_begin)
6969 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR

6976 Now constants, not macros.
6978 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
6980 Remove unnecessary casts involving pointers.
6981 These casts are no longer needed now that we assume C89 or later,
6982 since they involve casting to or from void *.

6984 (make_pure_float, make_pure_vector):
6985 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

6994 (x_get_window_property, x_get_window_property_as_lisp_data):
6995 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6996 Remove unnecessary pointer casts.
6997 * alloc.c (record_xmalloc): New function.
6998 * lisp.h (record_xmalloc): New decl.
6999 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7000 more like a function. This is because the pointer cast is not
7001 needed. All uses changed.
7002 * print.c (print_string, print_error_message): Avoid length recalc.
7004 Improve fix for macroexp crash with debugging (Bug#12118).
7005 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7006 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7007 not supposed to be invoked from the garbage collector.
7008 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7009 (gc_aset): New function, which is like ASET but can be
7010 used in the garbage collector.
7011 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

7023 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
7024 (map_w32_filename): Improve commentary. Simplify switch.
7025 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
7026 headers (most versions of MinGW w32api don't).
7027 (get_security_info, create_symbolic_link)
7028 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
7030 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks

7035 have the required privileges.
7036 (get_file_security_desc_by_name): Rename from
7037 get_file_security_desc.

7039 with addition of handling of symlinks and support for 'lstat'.
7040 If possible, get file's attributes and security information by
7041 handle, not by name. Produce S_IFLNK bit for symlinks, when
7042 called from 'lstat'.
7043 (stat, lstat): New functions, call 'stat_worker'.
7044 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7045 symlinks when the underlying filesystem supports them.
7047 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7049 Fix macroexp crash on Windows with debugging (Bug#12118).
7050 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7051 checking subscripts; problem introduced with the recent
7052 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7053 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7054 since it's used in non-static inline functions now.
7056 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7057 Don't assume buffer size fits in 'int'. Remove unused local.
7059 Use C99-style 'extern inline' if available.

7074 * category.c (CATEGORY_INLINE):
7075 * character.c (CHARACTER_INLINE):
7076 * charset.c (CHARSET_INLINE):
7077 * composite.c (COMPOSITE_INLINE):
7078 * dispnew.c (DISPEXTERN_INLINE):
7079 * sysdep.c (SYSTIME_INLINE):
7080 Define to EXTERN_INLINE, so that the corresponding functions
7081 are compiled into code.
7082 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7083 (INLINE_HEADER_END): New macros.
7084 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7104 hard-coding the path separator.
7106 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7108 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7109 This how ASET and AREF are supposed to work, and makes
7110 it easier to think about future improvements. See
7111 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7112 * charset.h (set_charset_attr): New function.

7604 the fix for 12036 would have avoided some of the problems noted in

7616 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7617 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7618 not be usable in #if. This simplifies things.
7620 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7622 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7627 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7628 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7629 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7630 Adjust to changes in lisp.h and emacs.c, by using

7633 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

7635 instead of gdb_valbits.
7636 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7637 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7638 instead of gdb_array_mark_flag.
7639 (xboolvector): Get size from $->size, not $->header.size.
7640 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7641 (xreload, hook-run, hookpost-run): Remove.
7642 * emacs.c: Include <verify.h>.
7643 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7644 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7646 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7647 (gdb_USE_LSB_TAG): New enum constants.
7648 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

7651 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

7656 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7657 more convenient now. All uses changed.
7658 (VALMASK) [USE_LSB_TAG]: Also define in this case.

7661 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

7666 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
7668 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,

8540 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8541 Prefer snprintf to strncpy.
8542 * nsterm.m (ns_term_init):
8543 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8544 * nsterm.m (ns_term_init):
8545 Avoid the need for strncpy, by using build_string or
8546 make_unibyte_string directly. Use dtoastr, not snprintf.
8547 * process.c (Fmake_network_process): Diagnose service names that
8548 are too long, rather than silently truncating them or creating
8549 non-null-terminated names.

8566 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8567 where argument type is known to be a Lisp_Cons.

8580 * lisp.h (make_pure_string): Fix prototype.
8581 (build_pure_c_string): New function, defined as static inline. This
8582 provides a better opportunity to optimize away calls to strlen when
8583 the function is called with compile-time constant argument.
8584 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8585 argument, adjust users accordingly. Use build_pure_c_string where
8587 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8588 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8589 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8591 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8593 Avoid calls to strlen in miscellaneous functions.
8594 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8595 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8596 * lread.c (openp): Likewise.
8598 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8600 Avoid calls to strlen in path processing functions.
8601 * fileio.c (file_name_as_directory): Add comment. Change to add
8602 srclen argument and return the length of result. Adjust users
8604 (directory_file_name): Fix comment. Change to add srclen argument,
8605 swap 1st and 2nd arguments to obey the common convention.
8606 Adjust users accordingly.
8607 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8609 2012-07-10 Glenn Morris <rgm@gnu.org>
8611 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
8612 Move PENDING_OUTPUT_COUNT definition to configure.
8614 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
8615 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
8616 * s/gnu.h (DATA_START): Move definitions to configure.
8618 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8619 We include usg5-4-common.h, which defines them both.
8621 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8622 O_RDONLY already includes it).
8624 Stop ns builds setting the EMACSLOADPATH environment variable.
8625 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8626 Now it does not set EMACSLOADPATH, just returns the load-path string.
8627 * nsterm.h: Update accordingly.
8628 * lread.c [HAVE_NS]: Include nsterm.h.
8629 (init_lread) [HAVE_NS]: Use ns_load_path.
8630 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
8632 2012-07-09 Glenn Morris <rgm@gnu.org>
8634 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8635 since the included bsd-common.h does so.
8637 Stop ns builds setting the EMACSPATH environment variable.
8638 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8639 (ns_init_paths): Do not set EMACSPATH.
8640 * nsterm.h (ns_exec_path): Add it.
8641 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8644 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8646 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8648 * process.c (wait_reading_process_output): 'waitchannels' was unset
8649 when read_kbd || !NILP (wait_for_cell); fix this.
8651 Add GCC-style 'const' attribute to functions that can use it.
8652 * character.h (char_resolve_modifier_mask):
8653 * keyboard.h (make_ctrl_char):
8654 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
8655 (init_character_once, next_almost_prime, init_fns, init_image)
8656 (flush_pending_output, init_sound):

8661 Declare the dummy function with ATTRIBUTE_CONST.
8662 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8663 Add decls with ATTRIBUTE_CONST.
8665 Minor improvements to make_formatted_string.
8666 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8667 where int is good enough, as vsprintf returns an int.
8668 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8670 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8672 Use make_formatted_string to avoid double length calculation.
8673 * lisp.h (make_formatted_string): New prototype.
8674 * alloc.c (make_formatted_string): New function.
8675 * buffer.c (Fgenerate_new_buffer_name): Use it.
8676 * dbusbind.c (syms_of_dbusbind): Likewise.
8677 * editfns.c (Fcurrent_time_zone): Likewise.
8678 * filelock.c (get_boot_time): Likewise.
8679 * frame.c (make_terminal_frame, set_term_frame_name)
8680 (x_report_frame_params): Likewise.
8681 * image.c (gs_load): Likewise.
8682 * minibuf.c (get_minibuffer): Likewise.

8694 * callproc.c [HAVE_NS]: Include nsterm.h.
8695 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
8697 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8699 Move marker debugging code under MARKER_DEBUG.
8700 * marker.c (MARKER_DEBUG): Move marker debugging code under
8701 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8702 for bootstrap with --enable-checking (~3x slowdown reported
8703 by Juanma Barranquero <lekktu@gmail.com>).
8704 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8706 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8708 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8709 See <http://bugs.gnu.org/11825#29>.
8711 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8713 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8714 has no font, use the frame's font. (Bug#11813)
8715 (display_line): Add commentary about displaying truncation glyphs
8717 (produce_special_glyphs): Move here from term.c.
8719 * term.c (produce_special_glyphs): Move to xdisp.c.
8721 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8724 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8726 * xdisp.c (display_line): Avoid warning about implicit declaration
8729 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8731 * lisp.h: Remove empty conditional.
8733 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8735 * lread.c (load_path_check): Now static.
8737 Fix some minor --with-ns problems found by static checking.
8738 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8739 (x_set_font) [!HAVE_X_WINDOWS]:
8740 * image.c (xpm_load_image) [HAVE_NS]:
8741 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8742 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8743 Remove unused local.
8744 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8745 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8746 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8747 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8748 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8749 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8750 Fix pointer signedness problem.
8751 * xfaces.c (FRAME_X_FONT_TABLE):
8752 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8754 2012-07-07 Glenn Morris <rgm@gnu.org>
8756 * lread.c (load_path_check): New function, split from init_lread.
8757 (init_lread): Reorganize. Motivation:
8758 If EMACSLOADPATH is set, check/warn about that rather than the
8759 defaults, which we are not going to use. Hence we can remove
8760 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8761 Don't warn if site-lisp directories are missing.
8762 If not installed, start from a blank load-path, since
8763 PATH_LOADSEARCH refers to the eventual installation directories.
8765 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8767 Support truncation and continuation glyphs on GUI frames, when
8768 fringes are disabled. (Bug#11832)
8769 * xdisp.c (init_iterator): Get dimensions of truncation and
8770 continuation glyphs even if on GUI frames.
8771 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8772 or both, are absent.
8773 (start_display, move_it_in_display_line_to): Handle the case of a
8774 GUI frame without a fringe to display continuation or truncation
8776 (insert_left_trunc_glyphs): Support GUI frames: make sure
8777 truncation glyphs overwrite enough glyphs from the current line to
8778 have sufficient space in pixels.
8779 (display_line): Support truncation and continuation glyphs on GUI
8780 frames. If some spare pixels are left on the line after inserting
8781 the truncation glyphs, fill that space with a stretch glyph of a
8782 suitably computed width.
8784 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8785 produce_glyphs, to support GUI sessions.
8787 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8789 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8791 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8793 Do not require float-time's arg to fit in time_t (Bug#11825).
8794 This works better on hosts where time_t is unsigned, and where
8795 float-time is applied to the (negative) difference between two times.
8796 * editfns.c (decode_time_components): Last arg is now double *,
8797 not int *, and means to store all the result as a double, without
8798 worrying about whether the seconds part fits in time_t.
8799 All callers changed.
8800 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8801 All callers changed.
8802 (Ffloat_time): Do not fail merely because the specified time falls
8803 outside of time_t range.
8805 2012-07-07 Glenn Morris <rgm@gnu.org>
8807 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8813 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8814 Update dependencies.
8816 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8818 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8820 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

8822 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8823 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8824 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
8825 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
8827 * xfont.c (compare_font_names): Redo to omit the need for casts.
8829 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8831 * xfns.c (Fx_change_window_property): Doc fix.
8832 * w32fns.c (Fx_change_window_property): Doc fix.
8834 * w32fns.c (Fx_window_property): Accept the same arguments as the
8835 X Windows version. Doc fix.
8836 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8838 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8839 Eli Zaretskii <eliz@gnu.org>
8841 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8842 Windows-specific code from nt/config.nt moved here.
8843 Obsolete settings removed.
8845 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8847 * process.c: Avoid unnecessary calls to gettime.
8848 (wait_reading_process_output): Don't get the time of day
8849 when gobbling data immediately and not waiting, as there's no need
8850 for it in that case. This removes a FIXME.
8852 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8854 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8855 is defined (Bug#11768).
8857 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8859 Fix marker debugging code.
8860 * marker.c (byte_char_debug_check): Do not perform the check
8861 if buffer is not multibyte.
8862 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8863 Call byte_char_debug_check with correct arguments.
8865 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8867 Compile marker debugging code only if ENABLE_CHECKING is defined.
8868 * marker.c (byte_char_debug_check, count_markers):
8869 Use only if ENABLE_CHECKING is defined.
8870 (byte_debug_flag): Remove.
8871 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8872 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8874 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8876 Avoid code repetition in marker-related functions.
8877 * marker.c (attach_marker): New function.
8878 (Fset_marker, set_marker_restricted, set_marker_both)
8879 (set_marker_restricted_both): Use it.
8880 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8881 Consistently rename charno to charpos.
8882 (marker_position): Add eassert.
8883 (marker_byte_position): Convert to eassert.

8902 * window.c (save_window_save): Likewise.
8904 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8906 Do not use Fdelete_overlay in delete_all_overlays
8907 to avoid redundant calls to unchain_overlay.
8908 * buffer.c (drop_overlay): New function.
8909 (delete_all_overlays, Fdelete_overlay): Use it.
8910 * minibuf.c (get_minibuffer): Fix comment.
8912 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8914 Port to OpenBSD 5.1 amd64.
8915 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8916 This is needed for OpenBSD, and should be harmless on all BSD systems.
8917 Also, include <sys/sysctl.h>, as it should be available on all
8918 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8919 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8920 use p_pid member, not kp_proc.pid.
8922 2012-07-06 Glenn Morris <rgm@gnu.org>
8924 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8926 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8928 More xmalloc and related cleanup.

8937 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8939 Omit needless casts involving void * pointers and allocation.
8940 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8941 as the former is more robust if P's type is changed.
8942 Prefer xzalloc to xmalloc + memset 0.
8943 Simplify malloc-or-realloc to realloc.
8944 Don't worry about xmalloc returning a null pointer.
8945 Prefer xstrdup to xmalloc + strcpy.
8946 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8948 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8949 alloca of a constant.
8951 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8953 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8954 hscroll is larger than the line width. Fixes long and futile
8955 looping inside extend_face_to_end_of_line (on a TTY) producing
8956 glyphs that are not needed and thrown away.
8958 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

8986 * xdisp.c (window_hscroll_limited): New function.
8987 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8988 coordinates when window's hscroll is set to insanely large
8991 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8993 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

9054 * fileio.c (time_error_value): Check the right error number.
9055 Problem reported by Troels Nielsen in
9056 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9058 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9060 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9061 This should be fixed in a better way; see Eli Zaretskii in
9062 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9063 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9065 * fileio.c (time_error_value): Rename from special_mtime.
9066 The old name's problems were noted by Eli Zaretskii in
9067 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9069 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9070 This variable's comment says Emacs needs at least one GDB-visible
9071 symbol of type enum pvec_type, to work around GDB problems.
9072 The symbol's value doesn't matter.
9074 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9075 that causes compilation to fail on pre-C99 compilers.
9077 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9079 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

9082 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9084 * buffer.c (init_buffer_once): Fix initialization of
9085 headers for buffer_defaults and buffer_local_symbols.
9086 Reported by Juanma Barranquero <lekktu@gmail.com>.
9088 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9090 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9091 * lisp.h (enum pvec_type): Use fewer bits.
9092 (PSEUDOVECTOR_SIZE_BITS): New constant.
9093 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9094 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9095 change in pvec_type.
9096 (PSEUDOVECTOR_TYPEP): New macro.
9097 (TYPED_PSEUDOVECTORP): Use it.
9098 * fns.c (internal_equal): Adapt code to extract pvectype.

9102 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9103 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9104 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9105 abusing vector->header.next.nbytes.
9106 (live_vector_p): Use PVEC_TYPE.
9107 (mark_object): Adapt code to extract pvectype. Use switch.
9109 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9111 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9112 Tighten new eassert a bit.
9114 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9116 Fix compilation with --enable-gcc-warnings and -O1
9118 * doprnt.c (doprnt): Change type of tem to int, initialize
9119 to avoid compiler warning. Add eassert.
9120 * search.c (simple_search): Initialize match_byte to avoid
9121 compiler warning. Add eassert.
9123 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9125 Avoid weird behavior with large horizontal scrolls.
9126 Without this change, for example, large hscroll values would
9127 mess up Emacs's display on Fedora 15 x86, presumably due to
9128 overflows in int calculations in the display code.
9129 Also, if buffers had long lines, Emacs would freeze.
9130 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9131 (set_window_hscroll): New function, containing the old guts of
9132 Fset_window_hscroll. Return the clipped value.
9133 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9134 This avoids the need to check against PTRDIFF_MAX.
9136 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9138 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9140 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9142 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9144 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9145 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9146 since GCC 4.4.6 issues a bogus warning for them.
9148 Fix bugs in file timestamp newness comparisons.
9149 * fileio.c (Ffile_newer_than_file_p):
9150 * lread.c (Fload): Use full timestamp resolution of files,
9151 not just the 1-second resolution, so that files that are only
9152 slightly newer still count as newer.
9153 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9154 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9156 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9158 * fileio.c: Improve handling of file time marker. (Bug#11852)
9159 (special_mtime): New function.
9160 (Finsert_file_contents, Fverify_visited_file_modtime):
9161 Use it to set special mtime values consistently.
9163 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9165 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9166 marker for non-existing file. (Bug#11852)
9168 2012-07-03 Glenn Morris <rgm@gnu.org>
9170 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9171 and did not make it into globals.h).
9173 2012-07-03 Tom Tromey <tromey@redhat.com>
9175 * window.c (Fset_window_margins, Fset_window_fringes)

9211 2012-07-03 Glenn Morris <rgm@gnu.org>
9213 * lisp.h (Frandom): Make it visible to C.
9214 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9215 buffer for invisible buffers. (Bug#1229)
9217 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9219 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9220 values which aren't power of 2.
9221 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9222 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9225 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9227 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9229 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9231 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9233 * alloc.c (allocate_vector_block): Remove redundant
9234 calls to mallopt if DOUG_LEA_MALLOC is defined.
9235 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9236 avoid calls to mallopt if zero_vector is returned.
9238 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9240 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9241 is enabled, avoid dereferencing NULL current_sblock if
9244 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9246 Cleanup basic buffer management.
9247 * buffer.h (struct buffer): Change layout to use generic vector
9248 marking code. Fix some comments. Change type of 'clip_changed'
9249 to bitfield. Remove unused #ifndef old.
9250 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9251 (GET_OVERLAYS_AT): Fix indentation.
9252 (for_each_per_buffer_object_at): New macro.
9253 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

9255 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
9256 * alloc.c (allocate_buffer): Adjust to match new layout of
9257 struct buffer. Fix comment.
9258 (mark_overlay): New function.
9259 (mark_buffer): Use it. Use mark_vectorlike to mark normal
9260 Lisp area of struct buffer.
9261 (mark_object): Use it. Adjust marking of misc objects
9262 and related comments.
9264 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9266 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9267 wrapper that is not needed because the wrapped code is a no-op (zero
9268 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9269 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9271 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9273 * alloc.c (mark_buffer): Simplify. Remove prototype.
9274 (mark_object): Add comment. Reorganize marking of vector-like
9275 objects. Use CHECK_LIVE for all vector-like objects except buffers
9276 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9277 Avoid redundant calls to mark_vectorlike for bool vectors.
9279 2012-06-30 Glenn Morris <rgm@gnu.org>
9281 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9283 * epaths.in (PATH_SITELOADSEARCH): New.
9284 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9285 This is rather than relying on --enable-locallisppath elements
9286 having "site-lisp" in their names. (Bug#10208#25, 11658)
9288 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9290 * w32proc.c (sys_select): Accept and ignore one more argument.
9292 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9294 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9295 (pselect) [!MS_DOS]: Redirect to sys_select.
9297 * sysdep.c: Don't include dos.h and dosfns.h.
9299 * process.c (sys_select):
9300 * msdos.c (sys_select): Accept one more argument and ignore it.
9302 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9303 adapt data types and code to that.
9306 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9307 which clashes with the gnulib function of the same name.
9309 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9311 * font.c (font_style_to_value, font_style_symbolic)
9312 (font_prop_validate_style): Add type checks for values in
9315 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9317 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9320 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9322 * xdisp.c (try_window_id): Undo last change.
9324 * w32.c (getwd): Adjust commentary about startup_dir.
9325 (init_environment): Always call sys_access, even in non-MSVC
9326 builds. Don't chdir to the directory of the Emacs executable.
9327 This undoes code from 1997 which was justified by the need to
9328 "avoid conflicts when removing and renaming directories". But its
9329 downside was that every relative file name was being interpreted
9330 relative to the directory of the Emacs executable, which can never
9331 be TRT. In particular, it broke sys_access when called with
9332 relative file names.
9333 (sys_access): Map GetLastError to errno.
9335 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9337 * window.h (struct window): Change type of 'fringes_outside_margins'
9338 to bitfield. Fix comment. Adjust users accordingly.
9339 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
9341 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9344 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9346 * gnutls.c (emacs_gnutls_handshake):
9347 Add QUIT to make the loop interruptible.
9349 2012-06-29 Glenn Morris <rgm@gnu.org>
9351 * charset.c (init_charset): Make lack of etc/charsets fatal.
9353 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9355 * editfns.c (region_limit): Fix type mismatch.
9357 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9359 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
9360 undefined. Convert from xassert to eassert.
9361 * nsmenu.m: Convert from xassert to eassert.
9362 * nsterm.m: Likewise.
9364 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9366 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9368 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9370 Avoid integer overflow on scroll-left and scroll-right.
9371 * window.c (HSCROLL_MAX): New macro.
9372 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9373 overflow when requested scroll falls outside ptrdiff_t range.
9375 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9377 * window.h (struct window): Change type of 'hscroll',
9378 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9379 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9380 Adjust users accordingly.
9381 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9382 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9383 from EMACS_INT to ptrdiff_t.
9384 (make_window): Omit redundant initialization.
9386 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

9390 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9392 * window.h (struct window): Change type of 'use_time' and

9455 avoid GCC warning about unused macro.
9457 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9459 * alloc.c (allocate_string): Omit intervals initialization.
9460 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9461 as in make_pure_string and make_pure_c_string.
9463 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9465 * alloc.c (allocate_string): Fix last change.
9467 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9517 * alloc.c: Remove build_string.
9518 * lisp.h: Define build_string as static inline. This provides
9519 a better opportunity to optimize away calls to strlen when the
9520 function is called with compile-time constant argument.
9521 * image.c (imagemagick_error): Convert to build_string.
9522 * w32proc.c (sys_spawnve): Likewise.
9523 * xterm.c (x_term_init): Likewise.
9525 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9527 Use sprintf return value instead of invoking strlen on result.
9528 In the old days this wasn't portable, since some sprintf
9529 implementations returned char *. But they died out years ago and
9530 Emacs already assumes sprintf returns int.
9531 Similarly for float_to_string.
9532 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

9540 Use sprintf or float_to_string result to avoid need to call strlen.
9541 * data.c (Fnumber_to_string):
9542 Use make_unibyte_string, since the string must be ASCII.
9543 * lisp.h, print.c (float_to_string): Now returns int length.
9544 * term.c (produce_glyphless_glyph):
9545 Use sprintf result rather than recomputing it.
9547 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

9650 when time_t is unsigned and as wide as intmax_t.
9651 See <http://bugs.gnu.org/9000#51>.

9682 language ID in the event parameters.
9684 * w32term.c (w32_read_socket): Put the new keyboard codepage into

9714 Don't assume EMACS_TIME and struct timeval are the same type.
9716 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9718 Support higher-resolution time stamps (Bug#9000).
9719 The time stamps are only nanosecond-resolution at the C level,
9720 since that's the best that any real-world system supports now.
9721 But they are picosecond-resolution at the Lisp level, as that's
9722 easy, and leaves room for future OS improvements.
9724 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9727 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9728 Don't get current time unless it's needed.
9730 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9731 now provides it if it's absent.
9732 (start_atimer): Port to higher-res time stamps.
9733 Check for time stamp overflow. Don't get current time more
9734 often than is needed.
9736 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9737 Include systime.h, not time.h.
9738 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9740 * dired.c: Include stat-time.h.
9741 (Ffile-attributes): File times now have higher resolution.

9744 (struct image): Timestamp now has higher resolution.
9746 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9747 has at least microseconds now. All uses removed.
9748 (update_frame, update_single_window, update_window, update_frame_1)
9749 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9750 (duration_to_sec_usec): Remove; no longer needed.
9752 * editfns.c (time_overflow): Now extern.

9758 (decode_time_components, lisp_seconds_argument): New functions.
9759 (make_time): Now static.
9760 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9761 Report an error if the time is invalid, rather than having the caller
9764 * fileio.c: Include <stat-time.h>
9765 (Fcopy_file): Copy higher-resolution time stamps.
9766 Prefer to set the time stamp via a file descriptor if that works.
9767 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9768 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9769 (Fvisited_file_modtime, Fset_visited_file_modtime):
9770 Support higher-resolution time stamps.
9772 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9774 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9776 * image.c (prepare_image_for_display, clear_image_cache)
9777 (lookup_image): Port to higer-resolution time stamps.
9779 * keyboard.c (start_polling, bind_polling_period):
9780 Check for time stamp overflow.
9781 (read_char, kbd_buffer_get_event, timer_start_idle)
9782 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9783 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9784 Port to higher-resolution time stamps. Do not assume time_t is signed.
9785 (decode_timer): New function. Timers are now vectors of length 9,
9786 not 8, to accommodate the picosecond component.
9787 (timer_check_2): Use it.
9789 * nsterm.m (select_timeout, timeval_subtract): Remove.
9790 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9791 as they're a bit more accurate and handle overflow better.
9792 (ns_select): Change prototype to be compatible with pselect.
9793 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9794 * nsterm.h (ns_select): Adjust prototype.
9796 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9797 us-resolution time stamps.
9798 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9800 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9802 * lisp.h (time_overflow): New decl.
9803 (wait_reading_process_output): First arg is now intmax_t, not int,
9804 to accommodate larger waits.
9806 * process.h (struct Lisp_Process.read_output_delay):
9807 Now counts nanoseconds, not microseconds.
9808 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9810 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9811 (wait_reading_process_output):
9812 Port to ns-resolution time stamps.
9813 (Faccept_process_output, wait_reading_process_output):
9814 Check for time stamp overflow. Do not assume time_t is signed.
9815 (select_wrapper): Remove; we now use pselect.
9816 (Fprocess_attributes): Now generates ns-resolution time stamps.
9818 * sysdep.c: Include utimens.h. Don't include utime.h
9819 or worry about struct utimbuf; gnulib does that for us now.
9820 (gettimeofday): Remove; gnulib provides a substitute.
9821 (make_timeval): New function.
9822 (set_file_times): Now sets ns-resolution time stamps.
9823 New arg FD; all uses changed.
9824 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9825 (system_process_attributes):
9826 Now returns ns-resolution time stamp. All uses changed.
9827 Check for time stamp overflow.
9829 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9830 provides a substitute now.
9832 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9833 since it guarantees struct timespec.
9834 (EMACS_TIME): Now struct timespec, so that we can support
9835 ns-resolution time stamps.
9836 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9837 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9838 (EMACS_USECS): Remove.
9839 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9840 so multiply the arg by 1000 before storing it.
9841 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9843 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9844 Port to ns-resolution time stamps.
9845 (EMACS_TIME_NEG_P): Remove; replaced by....
9846 (EMACS_TIME_SIGN): New macro.
9847 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9848 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
9849 (set_file_times, make_time, lisp_time_argument): Adjust signature.
9850 (make_timeval, make_lisp_time, decode_time_components): New decls.
9851 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9852 that it mishandled time_t overflow. You can't compare by subtracting!
9853 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9854 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9856 * term.c: Include <sys/time.h>.
9857 (timeval_to_Time): New function, for proper overflow wraparound.

9860 * undo.c (record_first_change): Support higher-resolution time stamps
9862 (Fprimitive_undo): Use them when restoring time stamps.
9864 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9865 (w32_get_internal_run_time):
9866 Port to higher-resolution Emacs time stamps.
9867 (ltime): Now accepts single 64-bit integer, as that's more convenient
9870 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9872 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9873 for compatibility with pselect. Support ns-resolution time stamps.
9875 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9877 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9878 Check for time stamp overflow, and support ns-resolution time stamps.
9880 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9881 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9882 (timeval_subtract): Remove; no longer needed.
9883 (XTflash, XTring_bell, x_wait_for_event):
9884 Port to ns-resolution time stamps. Don't assume time_t is signed.
9886 2012-06-22 Chong Yidong <cyd@gnu.org>
9888 * xdisp.c (x_consider_frame_title): Revert last change.
9890 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9892 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9893 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9894 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9895 staticidx goes up to 1597 out of 1600 = 0x640.)
9897 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9899 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9900 Otherwise, the umask might be mistakenly 0 while handling input signals.
9902 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
9904 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

9910 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
9911 access to `contents' member of Lisp_Vector objects with AREF and ASET
9914 2012-06-19 Chong Yidong <cyd@gnu.org>
9916 * frame.c (delete_frame): When selecting a frame on a different
9917 text terminal, do not alter the terminal's top-frame.

9921 (unwind_format_mode_line): Restore them.
9922 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9924 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9925 since tty frames can be explicitly named.
9926 (prepare_menu_bars): Likewise.
9928 * term.c (Ftty_top_frame): New function.
9930 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

9933 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9934 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9935 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9936 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
9937 (METER_1, METER_2): Simplify.
9939 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
9941 * data.c (Fdefalias): Return `symbol' (bug#11686).
9943 2012-06-18 Martin Rudalics <rudalics@gmx.at>
9945 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9946 gets killed during executing of this function (Bug#11665).
9947 Try to always return Qt when the buffer has been actually killed.
9948 (Vkill_buffer_query_functions): In doc-string say that functions
9949 run by this hook should not change the current buffer.
9951 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9953 Fix recently-introduced process.c problems found by static checking.
9954 * process.c (write_queue_push, write_queue_pop, send_process):

9957 (send_process): Remove unused local.
9959 2012-06-17 Chong Yidong <cyd@gnu.org>

9962 frames that are not on top.
9964 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
9966 * process.c (make_process): Initialize write_queue.
9967 (write_queue_push, write_queue_pop): New functions.

9971 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
9973 * lisp.h (eassert): Assume C89 or later.
9974 This removes the need for CHECK.
9975 (CHECK): Remove. Its comments about always evaluating its
9976 argument were confusing, as 'eassert' typically does not evaluate
9979 * coding.c (produce_chars): Use ptrdiff_t, not int.
9981 * xterm.c (x_draw_underwave): Check for integer overflow.
9982 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
9984 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
9986 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

10170 Use an inline function on all platforms when using the union type,

10315 * doprnt.c (doprnt): Truncate multibyte char correctly.
10316 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
10317 would mishandle a string argument "Xc" if X was a multibyte
10318 character of length 2: it would truncate after X's first byte
10319 rather than including all of X.

10372 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10373 Convert pctcpu and pctmem to Lisp float properly.
10374 Let the compiler fold better, as 100.0/0x8000 is exact.

10378 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

10390 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10391 change its type from Lisp_Object to bitfield.

10400 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10401 Use 'float' consistently, rather than 'float' in most places
10402 and 'double' in a couple of places.
10404 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10406 * xdisp.c (handle_stop): Detect whether we have overlay strings
10407 loaded by testing it->current.overlay_string_index to be
10408 non-negative, instead of checking whether n_overlay_strings is
10409 positive. (Bug#11587)

10426 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10427 for the duration of call to load_charset, to avoid problems with

10432 decrement the inhibition flag, instead of just setting or

10438 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

10452 * emacs.c: Include <sys/gmon.h> when profiling.
10453 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10454 (__executable_start): Remove decl, since lisp.h does it now.
10455 (safe_bcopy): Remove decl; no longer has that name.
10456 (main): Coalesce #if into single bit of code, for simplicity.
10457 Cast pointers to uintptr_t, since standard libraries want integers
10459 * lisp.h (__executable_start): New decl.
10461 2012-05-31 Glenn Morris <rgm@gnu.org>
10463 * image.c (Fimagemagick_types): Doc fix.

10484 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10486 Do not create empty overlays with the evaporate property (Bug#9642).
10487 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10488 Bug#9642, but explicitly check that the buffer the overlay would
10489 be moved to is live and rearrange lines to make sure that errors
10490 will not put the overlay in an inconsistent state.
10491 (Fdelete_overlay): Cosmetics.
10493 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10495 * w32term.c (my_bring_window_to_top): New function.
10496 (x_raise_frame): Use handle returned by DeferWindowPos, which
10497 could be different from the original one.

10507 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10509 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10510 This avoids undefined behavior that might cause the eassert
10511 to not catch an out-of-range value.
10513 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10515 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10516 Update dependencies.
10518 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10520 * bidi.c (bidi_mirror_char): Fix last change.
10522 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

10525 when referring to sectname field in printf format.
10527 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10529 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10530 Only r_alloc_inhibit_buffer_relocation needed to be added;
10531 the others were already declared.
10533 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10534 before checking whether it's out of range. Put the check inside
10536 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10538 2012-05-27 Ken Brown <kbrown@cornell.edu>
10540 * callproc.c (Fcall_process): Restore a line that was accidentally
10541 commented out in the 2011-02-13 change (bug#11547).
10543 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10545 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10546 defined on ralloc.c.
10548 * buffer.c [REL_ALLOC]: Remove prototypes of
10549 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10550 they are now on lisp.h.
10552 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10554 * search.c (search_buffer): Use it to inhibit relocation of buffer
10555 text while re_search_2 is doing its job, because re_search_2 is
10556 passed C pointers to buffer text. (Bug#11519)
10558 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10559 Update value to 24.
10561 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10562 state after an additional call to move_it_in_display_line_to, keep
10563 the values of it->max_ascent and it->max_descent found for the
10565 (pos_visible_p): Revert the comparison against bottom_y to what it
10566 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10569 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10571 Fix coding-related core dumps with gcc -ftrapv.
10572 The code was computing A - B, where A and B are pointers, and B is
10573 random garbage. This can lead to core dumps on platforms that
10574 have special pointer registers, and it also leads to core dumps on
10575 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10576 A - B only when B is initialized properly.
10577 * coding.c (coding_set_source, coding_set_destination): Return void.
10578 (coding_change_source, coding_change_destinations): New functions,
10579 with the old behaviors of coding_set_source and coding_set_destination.
10580 All callers that need an offset changed to use these new functions.
10582 2012-05-26 Glenn Morris <rgm@gnu.org>
10584 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
10586 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10588 Extend mouse support on W32 text-mode console.
10589 * xdisp.c (draw_row_with_mouse_face):
10590 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10592 * w32console.c: Include window.h.
10593 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10595 (initialize_w32_display): Initialize mouse-highlight data.
10597 * w32inevt.c: Include termchar.h and window.h.
10598 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10599 moves, call note_mouse_highlight. If help_echo changed, call
10600 gen_help_event to produce help-echo message in the echo area.
10601 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10604 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10606 * lread.c (read1): Simplify slightly to avoid an overflow warning
10607 with GCC 4.7.0 on x86-64.
10609 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10611 * bidi.c (bidi_mirror_char): Revert last change: an int is
10612 definitely wide enough here.
10614 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10616 Fix integer width and related bugs (Bug#9874).

10618 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
10619 (string_bytes, check_sblock, allocate_string_data):

10623 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10624 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10626 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10627 (allocate_pseudovector):
10628 Use int, not EMACS_INT, where int is wide enough.
10629 (inhibit_garbage_collection, Fgarbage_collect):
10630 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10631 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10632 int might not be wide enough.
10633 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10634 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10635 (bidi_at_paragraph_end, bidi_find_paragraph_start)

10648 (Foverlay_recenter, last_overlay_modification_hooks_used)
10649 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10650 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10651 (validate_region): Omit unnecessary test for b <= e,
10652 since that's guaranteed by the previous test.
10653 (adjust_overlays_for_delete): Avoid pos + length overflow.
10654 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10655 (report_overlay_modification):
10656 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10657 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10658 Omit pointer cast, which isn't needed anyway, and doesn't work
10659 after the EMACS_INT -> ptrdiff_t change.
10660 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10661 * buffer.h: Adjust decls to match defn changes elsewhere.
10662 (struct buffer_text, struct buffer):
10663 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10664 Use EMACS_INT, not int, where int might not be wide enough.
10665 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10666 not int, to avoid needless 32-bit limit on 64-bit hosts.
10667 (exec_byte_code): Use tighter memory-full test, one that checks
10668 for alloca overflow. Don't compute the address of the object just
10669 before an array, as that's not portable. Use EMACS_INT, not
10670 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10671 * callint.c (Fcall_interactively):
10672 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10673 * callproc.c (call_process_kill, Fcall_process):
10674 Don't assume pid_t fits into an Emacs fixnum.
10675 (call_process_cleanup, Fcall_process, child_setup):

10679 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10680 (Fcall_process): Simplify handling of volatile integers.

10683 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10684 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10685 (casify_object): Avoid integer overflow when overallocating buffer.
10686 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10687 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10688 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10689 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10690 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10691 integers are now checked earlier. All uses replaced with XINT.
10693 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10694 For CCL_MapSingle, check that content and value are in int range.
10695 (ccl_driver, Fregister_code_conversion_map):
10696 Check that Vcode_version_map_vector is a vector.
10697 (resolve_symbol_ccl_program): Check that vector header is in range.
10698 Always copy the vector, so that we can check its contents reliably
10699 now rather than having to recheck each instruction as it's being
10700 executed. Check that vector words fit in 'int'.
10701 (ccl_get_compiled_code, Fregister_ccl_program)
10702 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10703 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10704 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10705 contents are in range.
10706 (Fccl_execute_on_string): Check that status is in range.
10707 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10708 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10709 Accept and return EMACS_INT, not int, because callers can pass values
10710 out of 'int' range.
10711 (c_string_width, strwidth, lisp_string_width, chars_in_text)
10712 (multibyte_chars_in_text, parse_str_as_multibyte)

10715 (string_escape_byte8, Fget_byte):
10716 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10717 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10718 avoid mishandling large integers.
10719 * character.h: Adjust decls to match defn changes elsewhere.
10720 * charset.c (load_charset_map_from_file, find_charsets_in_text)
10721 (Ffind_charset_region):
10722 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

10725 Don't assume fixnum fits in int.
10726 (load_charset_map_from_vector, Fmap_charset_chars):
10727 Remove now-unnecessary CHECK_NATNUMs.
10728 (Fdefine_charset_internal): Check ranges here, more carefully.
10729 Don't rely on undefined behavior with signed left shift overflow.
10730 Don't assume unsigned int fits into fixnum, or that fixnum fits
10731 into unsigned int. Don't require max_code to be a valid fixnum;
10732 that's not true for gb10830 4-byte on a 32-bit host. Allow
10733 invalid_code to be a cons, for the same reason. Require code_offset
10734 to be a character. Avoid int overflow if max_char is close
10736 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10737 this is intended anyway and avoids some undefined behavior.
10738 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10739 INDEX_TO_CODE_POINT, as that's what it expects.
10740 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10741 * charset.h (DECODE_CHAR): Return int, not unsigned;
10742 this is what was intended anyway, and it avoids undefined behavior.
10743 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10744 integer-overflow issues.
10745 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10746 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10747 where the argument is EMACS_INT, and this behavior is not intended.
10748 * chartab.c (Fmake_char_table, Fset_char_table_range)
10749 (uniprop_get_decoder, uniprop_get_encoder):
10750 Don't assume fixnum fits in int.
10751 * cmds.c (move_point): New function, that does the gist of
10752 Fforward_char and Fbackward_char, but does so while checking
10753 for integer overflow more accurately.
10754 (Fforward_char, Fbackward_char): Use it.
10755 (Fforward_line, Fend_of_line, internal_self_insert)
10756 (internal_self_insert):
10757 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10758 Fix a FIXME, by checking for integer overflow when calculating

10792 (consume_chars): Rewrite to not calculate an address outside buffer.
10793 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
10794 Don't access memory outside of the args array.
10795 (Fdefine_coding_system_internal): Check for charset-id overflow.
10796 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
10797 result of ENCODE_CHAR.
10798 * coding.h: Adjust decls to match defn changes elsewhere.
10799 (struct coding_system):

10816 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
10817 Do not attempt to compute the address of the object just before a
10818 buffer; this is not portable.

11523 2012-05-17 Juri Linkov <juri@jurta.org>
11525 * search.c (Fword_search_regexp, Fword_search_backward)
11526 (Fword_search_forward, Fword_search_backward_lax)
11527 (Fword_search_forward_lax): Move functions to isearch.el
11528 (bug#10145, bug#11381).
11530 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11532 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11534 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11536 * lread.c (init_obarray): Declare Qt and Qnil as special.
11538 2012-05-14 Glenn Morris <rgm@gnu.org>
11540 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11541 Put "libexec" before "bin", for the sake of init_callproc_1.
11543 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11545 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11547 * unexaix.c: Port to more-recent AIX compilers.
11548 (report_error, report_error_1, make_hdr, copy_sym)
11549 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11550 Make arguments const char *, not char *, to avoid violations of C
11551 standard and to fix some AIX warnings reported by Gilles Pion.
11553 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11555 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11556 already have overlays loaded.
11557 (handle_single_display_spec): Before returning without displaying
11558 fringe bitmap, synchronize the bidi iterator with the main display
11559 iterator, by calling iterate_out_of_display_property.
11560 (iterate_out_of_display_property): Detect buffer iteration by
11561 testing that it->string is a Lisp string.
11562 (get_next_display_element): When the current object is exhausted,
11563 and there's something on it->stack, call set_iterator_to_next to
11564 proceed with what's on the stack, instead of returning zero.
11565 (set_iterator_to_next): If called at the end of a Lisp string,
11566 proceed to consider_string_end without incrementing string
11567 position. Don't increment display vector index past the end of
11568 the display vector. (Bug#11417)
11569 (pos_visible_p): Don't report a position visible when move_it_to
11570 stopped at the last line of window, which happens to be scanned
11571 backwards by the bidi iteration. (Bug#11464)
11573 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11575 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11576 and right-margin display specs even if the spec is invalid or we
11577 are on a TTY, and thus unable to display on the fringes.
11578 That's because the text with the property will not be displayed anyway,
11579 so we need to signal to the caller that this is a "replacing"
11580 display spec. This fixes display when the spec is invalid or we
11583 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11585 * unexaix.c (make_hdr): Fix typo in prototype.
11586 This bug broke the build on AIX. Problem reported by Gilles Pion.
11588 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11590 * keyboard.c (kbd_buffer_get_event): Read special events also in
11591 batch mode. (Bug#11415)
11593 2012-05-12 Glenn Morris <rgm@gnu.org>
11595 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11597 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11599 * lisp.mk (lisp): Add newcomment.elc.
11601 2012-05-12 Glenn Morris <rgm@gnu.org>
11603 * Makefile.in (MKDIR_P): New, set by configure.
11604 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11606 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11608 Remove unused function hourglass_started.
11609 * dispextern.h (hourglass_started):
11610 * w32fns.c (hourglass_started):
11611 * xdisp.c (hourglass_started): Remove.
11613 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11615 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11616 Update dependencies.
11618 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11620 * xgselect.c (xg_select): Put maxfds+1 into a var.
11621 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11623 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11625 2012-05-10 Dave Abrahams <dave@boostpro.com>
11627 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11628 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11630 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11632 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11633 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11634 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11635 Initialize xd_registered_buses.
11637 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11639 Untag more efficiently if USE_LSB_TAG.
11640 This is based on a proposal by YAMAMOTO Mitsuharu in
11641 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11642 For an admittedly artificial (nth 8000 longlist) benchmark on
11643 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11644 Emacs's overall text size by 1%.
11645 * lisp.h (XUNTAG): New macro.
11646 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11647 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11648 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11649 * eval.c (Fautoload):
11650 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11651 * frame.h (XFRAME): Use XUNTAG.
11653 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11654 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11655 Remove unportable assumptions about print widths of types like
11657 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11658 intptr_t when converting between pointer and integer, to avoid GCC
11659 warnings about wrong width.
11661 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11663 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11664 stack for each reader_thread, instead of defaulting to 8MB
11665 determined by the linker. This avoids failures in creating
11666 subprocesses on Windows 7, see the discussion in this thread:
11667 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11669 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11671 Fix up display of the *Minibuf-0* buffer in the mini window.
11672 * keyboard.c (read_char): Don't clear the echo area if there's no
11674 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11675 contents of *Minibuf-0*) if there's no message displayed in its stead.
11677 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11679 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11682 2012-05-06 Chong Yidong <cyd@gnu.org>
11684 * lisp.mk (lisp): Update.
11686 2012-05-05 Jim Meyering <meyering@redhat.com>
11688 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11690 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11692 * data.c (PUT_ERROR): New macro.
11693 (syms_of_data): Use it. Add new error type `user-error'.
11694 * undo.c (user_error): New function.
11695 (Fprimitive_undo): Use it.
11696 * print.c (print_error_message): Adjust print style for `user-error'.
11697 * keyboard.c (user_error): New function.
11698 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11700 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11702 Do not limit current-time-string to years 1000..9999.
11703 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11704 (Fcurrent_time_string): Support any year that is supported by the
11705 underlying localtime representation. Don't use asctime, as it
11706 has undefined behavior for years outside the range -999..9999.
11708 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11710 Fix race conditions involving setenv, gmtime, localtime, asctime.
11711 Without this fix, interrupts could mess up code that uses these
11712 nonreentrant functions, since setting TZ invalidates existing
11713 tm_zone or tzname values, and since most of these functions return
11714 pointers to static storage.
11715 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11716 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11717 Grow the critical sections to include not just invoking
11718 localtime/gmtime, but also accessing these functions' results
11719 including their tm_zone values if any, and any related TZ setting.
11720 (format_time_string): Last arg is now struct tm *, not struct tm **,
11721 so that the struct tm is saved in the critical section.
11722 All callers changed. Simplify allocation of initial buffer, partly
11723 motivated by the fact that memory allocation needs to be outside
11724 the critical section.
11726 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11728 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11729 with RESET_INTERVAL.
11731 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11732 Remove duplicated buffer name initialization.
11734 2012-05-02 Jim Meyering <jim@meyering.net>
11736 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11738 * xfns.c (x_window): Use xstrdup (Bug#11375).
11740 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11742 * xdisp.c (pos_visible_p): If already at a newline from the
11743 display string before the 'while' loop, don't walk back the glyphs
11744 from it3.glyph_row. Solves assertion violation when the display
11745 string begins with a newline (egg.el). (Bug#11367)
11747 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11749 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11752 2012-05-01 Glenn Morris <rgm@gnu.org>
11754 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11755 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11756 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11757 All were removed before 23.1.
11759 * dispnew.c: Remove HAVE_LIBNCURSES test;
11760 it is always true on relevant platforms.
11762 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11763 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11765 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11767 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11769 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11770 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11773 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11775 Do not avoid creating empty evaporating overlays (Bug#9642).
11776 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11777 That is, do not delete an evaporating overlay if it becomes
11778 empty after its bounds are adjusted to fit within its buffer.
11779 This fix caused other problems, and I'm reverting it until we get
11780 to the bottom of them.
11782 2012-04-27 Chong Yidong <cyd@gnu.org>
11784 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11786 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11788 * xdisp.c (pos_visible_p): If the window start position is beyond
11789 ZV, start the display from buffer beginning. Prevents assertion
11790 violation in init_iterator when the minibuffer window is scrolled
11791 via the scroll bar.
11793 * window.c (window_scroll_pixel_based): Likewise.
11795 2012-04-27 Chong Yidong <cyd@gnu.org>
11797 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11799 2012-04-27 Glenn Morris <rgm@gnu.org>
11801 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11802 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11804 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11806 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11807 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11809 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11811 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11812 display element, check also the underlying string or buffer
11813 character. (Bug#11341)
11815 * w32menu.c: Include w32heap.h.
11816 (add_menu_item): If the call to AppendMenuW (via
11817 unicode_append_menu) fails, disable Unicode menus only if we are
11818 running on Windows 9X/Me.
11820 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11822 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11823 (xgetint): Add missing shift for LSB tags.
11825 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11827 * keyboard.c (read_char): Don't wipe echo area for select window
11828 events: These might get delayed via `mouse-autoselect-window'
11831 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11833 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11834 manipulation of :loaded-from data.
11836 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11838 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11839 now a cons (bug#11311).
11841 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11843 Do not create empty overlays with the evaporate property (Bug#9642).
11844 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11845 if it becomes empty after its bounds are adjusted to fit within
11846 its buffer. Without this fix, in a nonempty buffer (let ((o
11847 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11848 yields an empty overlay that has the evaporate property, which is
11849 not supposed to happen.
11851 Fix minor GTK3 problems found by static checking.
11852 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11853 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11854 (struct _EmacsFixedClass, emacs_fixed_get_type):
11855 Move decls here from emacsgtkfixed.h, since they needn't be public.
11856 (emacs_fixed_get_type): Now static.
11857 (emacs_fixed_class_init): Omit unused local.
11858 (emacs_fixed_child_type): Remove; unused.
11859 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11860 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11861 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11862 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11863 (EMACS_FIXED_GET_CLASS): Remove; unused.
11864 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11866 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11867 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11869 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11871 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11872 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11873 (__malloc_size_t, __malloc_ptrdiff_t):
11874 Remove. All uses removed, replaced by the definiens if needed,
11875 since we can assume C89 or better now.
11876 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

11884 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11885 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11886 Define using prototypes, not old style.
11887 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11888 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11889 (align): Don't assume that signed integer overflow wraps around.
11890 Omit unused local var.
11891 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
11892 (_free_internal_nolock, memalign, mallochook, reallochook):
11893 Omit no-longer-needed casts.
11894 (valloc): Use getpagesize, not __getpagesize.
11895 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11896 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11898 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11900 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11902 Move functions from C to Lisp. Make non-blocking method calls
11903 the default. Implement further D-Bus standard interfaces.
11905 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

11921 (xd_signature, xd_append_arg): Allow float for integer types.
11922 (xd_get_connection_references): New function.
11923 (xd_get_connection_address): Rename from xd_initialize.
11924 Return cached address.
11925 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
11926 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp
11928 (Fdbus_init_bus): New optional arg PRIVATE. Cache address.
11929 Return number of refcounts.
11930 (Fdbus_get_unique_name): Make stronger parameter check.
11931 (Fdbus_message_internal): New defun.

11945 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11947 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
11948 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
11949 Do not assume ptrdiff_t is the same width as 'int'.
11951 * alloc.c: Handle unusual debugging option combinations.
11952 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
11953 since the two debugging options are incompatible.
11954 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

11964 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11966 * sysdep.c [__FreeBSD__]: Minor cleanups.
11967 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11968 Use Emacs indenting style more consistently. Avoid some casts.
11969 Use 'double' consistently rather than mixing 'float' and 'double'.
11971 2012-04-21 Eduard Wiebe <usenet@pusto.de>
11973 * sysdep.c (list_system_processes, system_process_attributes):
11974 Add implementation for FreeBSD (Bug#5243).

11980 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
11982 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
11983 It is never used otherwise.
11985 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
11987 * print.c (print_preprocess): Only check print_depth if print-circle
11989 (print_object): Check for cycles even when print-circle is nil and
11990 print-gensym is t, but only check print_depth if print-circle is nil.
11992 2012-04-20 Chong Yidong <cyd@gnu.org>
11994 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11995 set the status to "failed" and ensure that sentinel is run.
11997 2012-04-20 Glenn Morris <rgm@gnu.org>
11999 * process.c (Fset_process_inherit_coding_system_flag)
12000 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

12008 row, return zero immediately.
12009 (try_cursor_movement): If inside continuation line, don't back up
12010 farther than the first row after the header line, if any.
12011 Don't consider the header-line row as "partially visible", even if
12012 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
12014 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

12023 * Makefile.in (C_WARNINGS_SWITCH): Remove.
12024 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
12025 (ALL_CFLAGS): Use new macros rather than old.
12026 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.

12028 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
12029 -Wunused-result, -Wunused-variable. This should go away once
12030 the Emacs and Gnulib regex code is merged.
12031 (xmalloc, xrealloc): Now static.
12033 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

12050 New extern decls, to avoid calling undeclared functions.
12051 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
12052 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12053 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12054 (NEED_MEM_INSERT): New macro.
12055 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12056 Remove one incorrect comment and fix another.

12070 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
12071 Remove decls. This fixes an "It stinks!".
12073 * alloc.c (which_symbols): Fix alignment issue / type clash.
12075 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
12077 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
12078 (struct Lisp_Misc_Any): Likewise.
12079 (struct Lisp_Free): Likewise.
12080 * alloc.c (union aligned_Lisp_Symbol): Define.

12088 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
12090 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
12091 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
12092 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12093 * s/netbsd.h, s/sol2-6.h:
12094 Remove definition of GC_MARK_STACK, since the default now works.
12095 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12096 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12097 no longer the default.
12098 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12100 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
12102 * lread.c (lisp_file_lexically_bound_p):
12103 Fix hang at ";-*-\n" (bug#11238).
12105 2012-04-14 Eli Zaretskii <eliz@gnu.org>
12107 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
12108 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

12119 2012-04-13 Reuben Thomas <rrt@sc3d.org>
12121 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
12123 2012-04-11 Daniel Colascione <dancol@dancol.org>
12125 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12126 against is gone. It's better to use vfork now so that when Cygwin
12127 gains a new, working vfork, we use it automatically (bug#10398).
12129 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
12131 * window.c (save_window_save): Obey window-point-insertion-type.

12147 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
12149 * w32.c (w32_delayed_load): Record the full path of the library
12150 being loaded (bug#10424).
12152 2012-04-09 Glenn Morris <rgm@gnu.org>
12154 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12155 not just in the obarray, before snarfing them. (Bug#11036)

12158 Pass EMACS rather than BUILT_EMACS.
12160 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
12162 * process.c (make_process):
12163 * process.h: Add integer `gnutls_handshakes_tried' member to
12166 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.

12169 * gnutls.c (gnutls_log_function2i): Convenience log function.
12170 (emacs_gnutls_read): Use new log functions,
12171 `gnutls_handshakes_tried' process member, and
12172 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12173 attempts per process (connection).
12175 2012-04-09 Chong Yidong <cyd@gnu.org>
12177 * eval.c (Fuser_variable_p, user_variable_p_eh)
12178 (lisp_indirect_variable): Functions deleted.
12179 (Fdefvar): Caller changed.
12181 * callint.c (Finteractive, Fcall_interactively):
12182 * minibuf.c (Fread_variable): Callers changed.
12184 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12186 * xdisp.c (set_cursor_from_row): If the display string appears in
12187 the buffer at position that is closer to point than the position
12188 after the display string, display the cursor on the first glyph of
12189 the display string. Fixes cursor display when a 'display' text
12190 property immediately follows invisible text. (Bug#11094)
12192 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12194 composite.c: use 'double' consistently
12195 * composite.c (get_composition_id): Use 'double' consistently
12196 instead of converting 'float' to 'double' and vice versa; this is
12197 easier to understand and avoids a GCC warning.
12199 2012-04-09 Glenn Morris <rgm@gnu.org>
12201 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12202 preparation for dumping it with emacs. (Bug#4789)
12203 (leimdir): New variable.

12223 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12224 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12225 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12226 objects, as mark_maybe_pointer will catch them otherwise.
12227 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12228 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12235 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12237 Support building on MS-Windows with libxml2.
12239 * makefile.w32-in (OBJ2): Add xml.$(O).
12240 (GLOBAL_SOURCES): Add xml.c.
12241 ($(BLD)/xml.$(O)): New dependency list.
12243 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12244 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12245 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12246 [!WINDOWSNT]: New macros.
12247 (init_libxml2_functions, libxml2_loaded_p): New functions.
12248 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12249 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12250 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12251 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12253 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12254 Call init_libxml2_functions before calling libxml2 functions.
12255 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12257 * emacs.c: Don't include libxml/parser.h.
12258 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12259 xmlCleanupParser directly.
12261 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12263 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12265 * indent.c (Fvertical_motion): If there is a display string at
12266 point, use it.vpos to compute how many lines to backtrack after
12267 move_it_to point. (Bug#11133)
12269 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12271 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12272 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12273 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12274 macros related to unification of CJK characters. For the details,
12275 see the discussion following the message here:
12276 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12278 2012-04-04 Chong Yidong <cyd@gnu.org>
12280 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12282 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12284 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12285 instead of alloca. (Bug#11138)
12287 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12289 * w32menu.c (is_simple_dialog): Properly check lisp types.
12292 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12294 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12295 position we get to after a call to move_it_to fails the
12296 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12297 only if we wind up in a string from display property. (Bug#11063)
12299 * window.c (Fdelete_other_windows_internal): Invalidate the row
12300 and column information about mouse highlight, so that redisplay
12301 restores it after reallocating the glyph matrices. (Bug#7464)
12303 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12304 string comes from a `display' text property, use the buffer
12305 position of that property as if we actually saw that position in
12307 (move_it_by_lines): Remove the assertion that
12308 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12309 violated when there's a before-string at the beginning of a line.
12312 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12314 * xdisp.c (append_space_for_newline): If the default face was
12315 remapped, use the remapped face for the appended newline.
12316 (extend_face_to_end_of_line): Use the remapped default face for
12317 extending the face to the end of the line.
12318 (display_line): Call extend_face_to_end_of_line when the default
12319 face was remapped. (Bug#11068)
12321 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12323 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12325 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12327 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12329 2012-03-27 Glenn Morris <rgm@gnu.org>
12331 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12334 2012-03-26 Kenichi Handa <handa@m17n.org>

12341 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12342 (command_loop_1): Use it; inhibit selection update for
12343 handle-select-window too (Bug#8996).

12347 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12349 2012-03-25 Kenichi Handa <handa@m17n.org>
12351 * dispextern.h (struct glyph): Change the bit length of
12352 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12354 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12356 * s/ms-w32.h (tzname): Include time.h before redirecting to
12357 _tzname. Fixes the MSVC build. (Bug#9960)
12359 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12361 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12364 * xterm.c (XTread_socket): Only modify handling_signal if
12365 !SYNC_INPUT. (Bug#11080)
12367 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12369 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12370 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12371 when fetching a multibyte character consumes more bytes than
12372 CHAR_BYTES returns, due to unification of CJK characters in
12373 string_char. (Bug#11073)
12375 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12377 * process.c (wait_reading_process_output): Handle pty disconnect
12378 by refraining from sending oneself a SIGCHLD (bug#10933).
12380 2012-03-22 Chong Yidong <cyd@gnu.org>
12382 * dispextern.h (struct it): New member string_from_prefix_prop_p.
12384 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12385 Mark string as coming from a prefix property.
12386 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12387 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12389 2012-03-21 Chong Yidong <cyd@gnu.org>
12391 * xfaces.c (Vface_remapping_alist): Doc fix.
12393 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12395 * w32proc.c (Fw32_set_console_codepage)
12396 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

12406 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12407 it fit in a valid range (Bug#11003).
12409 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12411 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12412 that is not from display property, accept the row as a "cursor
12413 row" if one of the string's character has a non-nil `cursor'
12414 property. Fixes cursor positioning when there are newlines in
12415 overlay strings, e.g. in icomplete.el. (Bug#11035)
12417 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

12451 2012-03-03 Glenn Morris <rgm@gnu.org>
12453 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12455 2012-03-02 Eli Zaretskii <eliz@gnu.org>

12459 (redisplay_window, next_element_from_string): Fix typos in
12461 (redisplay_window): Pass to move_it_vertically the margin in

12466 * buffer.c (buffer-list-update-hook): Doc fix.
12468 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12470 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12471 push_it before setting up the iterator for the first overlay
12472 string, even if we have an empty string loaded.
12473 (next_overlay_string): If there's an empty string on the iterator
12474 stack, pop the stack. (Bug#10903)
12476 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12478 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12479 Suggested by Stefan Monnier in
12480 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12481 * alloc.c (widen_to_Lisp_Object): New static function.
12482 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12483 and widening them to Lisp_Objects. This would work even if
12484 USE_LSB_TAG is defined and wide integers are used, which might
12485 happen in a future version of Emacs.
12487 2012-02-25 Chong Yidong <cyd@gnu.org>
12489 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

12498 * keyboard.c (process_special_events): Handle all X selection
12499 requests in kbd_buffer, not just the next one (Bug#8869).
12501 2012-02-23 Chong Yidong <cyd@gnu.org>
12503 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12504 call when setting menu-bar-lines and tool-bar-lines parameters.
12505 (unwind_create_frame_1): New helper function.
12507 * window.c (inhibit_window_configuration_change_hook): New var.

12526 when computing $valmask.
12528 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12529 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12530 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12531 It's useless in that case, and it can cause problems on hosts
12532 that allocate halves of EMACS_INT values separately.
12533 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12534 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12535 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12536 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12537 it avoids undefined behavior on hosts where shifting right by more
12538 than the word width has undefined behavior.
12540 2012-02-19 Chong Yidong <cyd@gnu.org>
12542 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12543 (Funhandled_file_name_directory, Ffile_name_as_directory)

12545 (Fsubstitute_in_file_name): Protect against invalid file handler
12546 return values (Bug#10845).

12562 2012-02-15 Chong Yidong <cyd@gnu.org>
12564 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

12580 2012-02-12 Chong Yidong <cyd@gnu.org>
12582 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12583 as that creates a dangerous corner case.
12585 * window.c (Fdelete_window_internal): Invalidate the mouse
12586 highlight (Bug#9904).
12588 2012-02-12 Glenn Morris <rgm@gnu.org>

12618 2012-02-07 Chong Yidong <cyd@gnu.org>
12620 * buffer.c (Fbuffer_local_variables)
12621 (buffer_lisp_local_variables): Handle unbound vars correctly;
12622 don't let Qunbound leak into Lisp.
12624 2012-02-07 Glenn Morris <rgm@gnu.org>
12626 * image.c (Fimagemagick_types): Doc fix.
12628 * image.c (imagemagick-render-type): Change it from a lisp object
12629 to an integer. Move the doc here from the lisp manual.

12659 before BEGV. (Bug#10696)
12661 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
12663 Handle overflow when computing char display width (Bug#9496).
12664 * character.c (char_width): Return EMACS_INT, not int.
12665 (char_width, c_string_width): Check for overflow when
12666 computing the width; this is possible now that individual
12667 characters can have unbounded width. Problem introduced
12668 by merge from Emacs 23 on 2012-01-19.

12692 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
12694 (x_produce_glyphs): If the component of a composition is a null

12699 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
12700 first 2 arguments are identical. This makes inserting large
12701 output from a subprocess an order of magnitude faster on
12702 MS-Windows, where all sbrk'ed memory is always contiguous.

12802 DISP_STRING, and accept any glyph in a row whose object is that
12803 string as eligible for mouse highlight. Fixes mouse highlight of
12804 display strings from overlays. (Bug#10464)
12806 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
12808 emacs: fix an auto-save permissions race condition (Bug#10400)

12810 (Fmake_directory_internal): Use it.

13321 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13322 is set, removing the need for VIRT_ADDRESS_VARIES.
13323 (PURE_P): Use a more-efficient implementation that needs just one

13326 to 4 (xorl, subq, cmpq, setbe).
13327 * alloc.c (pure): Always extern now, since that's the
13328 VIRT_ADDR_VARIES behavior.

13330 consistency with the new puresize.h.
13331 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

13338 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13339 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13340 behave as if the cursor position were at the window margin.
13342 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13343 and the cursor position is out of bounds, behave as if the cursor
13344 position were at the window margin. (Bug#10075)
13346 2011-11-18 Chong Yidong <cyd@gnu.org>
13348 * window.c (Fwindow_combination_limit): Make first argument

13421 Fixes assertion violations in row_equal_p. (Bug#10035)
13423 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

13572 static_offset_intervals. The old version didn't conform to C99
13573 because an extern inline function contained a reference to an
13574 identifier with static linkage.

13824 2011-10-27 Chong Yidong <cyd@gnu.org>
13826 * process.c (make_process): Set gnutls_state to NULL.
13828 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13829 non-NULL, regardless of GNUTLS_INITSTAGE.
13830 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13831 an error. Set process slots as soon as we allocate them.
13833 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13835 2011-10-27 Chong Yidong <cyd@gnu.org>
13837 * gnutls.c (emacs_gnutls_deinit): New function.
13838 Deallocate credentials structures as well as calling gnutls_deinit.
13839 (Fgnutls_deinit, Fgnutls_boot): Use it.
13841 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13842 (deactivate_process): Call emacs_gnutls_deinit.
13844 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13846 * image.c (x_create_x_image_and_pixmap):
13847 * w32.c (sys_rename, w32_delayed_load):
13848 * w32font.c (fill_in_logfont):
13849 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13851 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13853 * w32fns.c (w32_default_color_map): New function,
13854 extracted from Fw32_default_color_map.
13855 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13857 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13859 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13861 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13863 * keyboard.c (test_undefined): New function (bug#9751).
13864 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13866 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13868 * sysdep.c (init_sys_modes): Fix the check for the controlling
13869 terminal (Bug#6649).
13871 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13873 * dispextern.h (struct bidi_it): New member next_en_type.
13875 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13876 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13877 current character, check also for next_en_type being WEAK_EN.
13878 (bidi_resolve_weak): Don't enter the expensive loop if the current
13879 position is before next_en_pos. Record the bidi type of the first
13880 non-ET, non-BN character we find, in addition to its position.
13881 (bidi_level_of_next_char): Invalidate next_en_type when
13882 next_en_pos is over-stepped.
13884 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13886 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13887 * editfns.c: Rewrite current-time-zone so that it invokes
13888 the equivalent of (format-time-string "%Z") to get the time zone name.
13889 This fixes a bug when the time zone name contains characters that
13890 need converting from the system time locale to Emacs internal format.
13891 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13892 that patch fixed format-time-string to do the conversion, but
13893 I forgot to fix current-time-zone.
13894 (format_time_string): New function, containing most of
13895 what Fformat_time_string used to contain.
13896 (Fformat_time_string): Rewrite in terms of format_time_string.
13897 This doesn't change this function's behavior.
13898 (current-time-zone): Rewrite to use format_time_string.
13899 This fixes the bug reported by Michael Schierl in
13900 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13901 Jason Rumney's 2007-06-07 change worked around this bug, but
13903 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13905 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13907 * xdisp.c (start_display): If the character at POS is displayed
13908 via a display vector, reset IT->current.dpvec_index to zero.
13909 (try_window_reusing_current_matrix): If a line ends in a display
13910 vector or the next line starts in a display vector, continue
13911 redrawing the window even though the character position of
13912 start_row was reached.
13915 2011-10-18 Chong Yidong <cyd@gnu.org>
13917 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13918 with nobreak-char-display too.
13920 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13922 Fix part 3 of bug#9771.
13923 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13924 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13925 non-neutral characters if the current character is a paragraph
13926 separator (a.k.a. Newline). This avoids running the same
13927 expensive loop twice, once when we consume the preceding newline
13928 and the other time when the line actually needs to be displayed.
13929 Avoid the loop when we see neutrals on the base embedding level
13930 following a character whose directionality is the same as the
13931 paragraph's. This avoids running the expensive loop when a line
13932 ends in a long sequence of neutrals, like control characters.
13933 Add assertion against STRONG_AL type. Slightly rearrange code
13934 that determines the type of a neutral given the first non-neutral
13936 (bidi_level_of_next_char): Set next_en_pos to zero when
13937 invalidating its info.
13939 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13941 * xdisp.c (push_display_prop): Determine whether to record string
13942 or buffer position by IT->string, not by IT->method. Allow
13943 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13944 (move_it_vertically_backward): Don't look for character position
13945 immediately after the newline when in a continuation line.
13948 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13950 * window.c (coordinates_in_window): Rewrite and delabelize
13951 vertical border check. (Bug#5357) (Bug#9618)
13953 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13955 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13956 errors in XSetWindowBorder (bug#9310).
13958 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13960 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13961 avoid crash when xmalloc overrun checking is enabled.
13963 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13965 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13966 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13967 cursor motion with <left> and <right> arrow keys.
13969 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13970 some callers set that themselves.
13972 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13974 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13975 display string and the previous row comes from the same string and
13976 is empty. (Bug#9739) (Bug#9738)
13978 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13980 * doc.c (get_doc_string): Encode file name (bug#9735).
13982 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13984 * bidi.c (bidi_level_of_next_char):
13985 * xdisp.c (get_visually_first_element): Remove old incorrect
13986 comments regarding the Unicode Line Separator character.
13988 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13990 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13992 * alloc.c (Fgc_status): Do not access beyond zombies array
13993 boundary if nzombies > MAX_ZOMBIES.
13994 * alloc.c (dump_zombies): Add missing format specifier.
13996 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13998 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13999 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14001 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14002 Some packages use them to denote characters with modifiers.
14004 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14006 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14007 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14008 matching a pp-number. Rename parameter var to var1.
14010 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14012 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14014 2011-10-08 Glenn Morris <rgm@gnu.org>
14016 * callint.c (Fcall_interactively): Give a more explicit error for the
14017 'c' case with a non-character input. (Bug#8479)
14019 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14021 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14023 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14024 lines that are hscrolled on the left.
14026 * dispnew.c (buffer_posn_from_coords): Account for a possible
14027 presence of header-line. (Bug#4426)
14029 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14031 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14032 Don't advertise functionality which we discourage or doesn't work.
14034 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14036 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14037 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14038 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14039 this makes Emacs dump core during garbage collection on rare
14040 occasions. sizeof is obviously inferior to offsetof here, so
14041 stick with offsetof.
14042 (GC_POINTER_ALIGNMENT): New macro.
14043 (mark_memory): Omit 3rd (offset) arg; caller changed.
14044 Don't assume EMACS_INT alignment is the same as pointer alignment.
14046 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14048 * keyboard.c (read_key_sequence_remapped): New var.
14049 (read_key_sequence): Compute remapping in the right buffer.
14050 (command_loop_1): Use read_key_sequence's remapping directly.
14052 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14054 * dired.c (file_name_completion): Don't expand file name.
14055 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14056 before checking file name handler.
14058 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14059 they've been requested explicitly (bug#9591).
14061 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14063 * keymap.c (Fsingle_key_description): Use make_specified_string
14064 instead of build_string to build string from push_key_description.
14067 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14069 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14070 This fixes a Y2038 bug on 64-bit hosts.
14071 * buffer.c (reset_buffer):
14072 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14073 (Fclear_buffer_auto_save_failure):
14074 Use 0, not -1, to represent an unset failure time, since time_t
14075 might not be signed.
14077 Remove dependency on glibc malloc internals.
14078 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14079 Move back here from lisp.h, but with their new implementations.
14080 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14081 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14082 * charset.c (charset_table_init): New static var.
14083 (syms_of_charset): Use it instead of xmalloc. This removes a
14084 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14085 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14086 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14087 Move back to alloc.c.
14088 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14089 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14091 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14093 * nsterm.m (windowDidResize): Call x_set_window_size only when
14094 ns_in_resize is true. Otherwise set pixelwidth/height and
14095 call change_frame_size (Bug#9628).
14097 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14099 Port --enable-checking=all to Fedora 14 x86-64.
14100 * charset.c (syms_of_charset): Also account for glibc malloc's
14101 internal overhead when calculating the initial malloc maximum.
14103 Port --enable-checking=all to Fedora 14 x86.
14104 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14106 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14107 (overrun_check_realloc, overrun_check_free):
14108 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14109 That way, xmalloc returns a properly-aligned pointer even if
14110 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14111 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14112 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14113 into account when calculating the initial malloc maximum.
14114 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14115 Move here from alloc.c, so that charset.c can use it too.
14116 Properly align; the old code wasn't right for common 32-bit hosts
14117 when configured with --enable-checking=all.
14118 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14119 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14121 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14123 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14126 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14128 * xdisp.c (compute_display_string_end): If there's no display
14129 string at CHARPOS, return -1.
14131 * bidi.c (bidi_fetch_char): When compute_display_string_end
14132 returns a negative value, treat the character as a normal
14133 character not covered by a display string. (Bug#9624)
14135 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14137 * lread.c (Fread_from_string): Fix typo in docstring.
14139 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14141 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14142 newline, reseat the iterator instead of bidi-iterating there one
14143 character at a time. (Bug#9610)
14144 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14145 TO_CHARPOS if the bidi iterator is at base embedding level.
14147 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14149 * lread.c (readevalloop): Use correct code for NBSP.
14150 (read1): Likewise. (Bug#9608)
14152 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14154 * dbusbind.c (Fdbus_register_signal): When service is not
14155 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14157 2011-09-25 Glenn Morris <rgm@gnu.org>
14159 * buffer.c (truncate-lines): Doc fix.
14161 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14163 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14164 (Fset_window_next_buffers): Doc fix.
14166 2011-09-24 Glenn Morris <rgm@gnu.org>
14168 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14170 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14172 Fix minor problems found by static checking.
14173 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14174 * indent.c (Fvertical_motion): Fix == vs = typo.
14176 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14178 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14179 Default value is now t. Doc fix.
14181 * indent.c (Fvertical_motion): Compute and apply the overshoot
14182 logic when moving up, not only when moving down. Fix the
14183 confusing name and values of the it_overshoot_expected variable;
14184 logic changes accordingly. (Bug#9254) (Bug#9549)
14186 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14187 CHARPOS is covered by a display string which includes newlines.
14188 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14189 is covered by a display string with embedded newlines.
14191 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14193 * dbusbind.c (Fdbus_register_signal): Add match rule to
14194 Vdbus_registered_objects_table. (Bug#9581)
14195 (Fdbus_register_method, Vdbus_registered_objects_table):
14198 2011-09-24 Jim Meyering <meyering@redhat.com>
14200 do not ignore write error for any output size
14201 The previous change was incomplete.
14202 While it makes emacs --batch detect the vast majority of stdout
14203 write failures, errors were still ignored whenever the output size is
14204 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14205 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14206 && echo FAIL: ignored write error
14207 FAIL: ignored write error
14208 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14209 && echo FAIL: ignored write error
14210 FAIL: ignored write error
14211 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14213 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14215 * emacs.c (Fkill_emacs): In noninteractive mode exit
14216 non-successfully if a write error occurred on stdout. (Bug#9574)
14218 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14220 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14223 * dispextern.h (struct it): Update the comment documenting what
14226 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14228 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14229 a display string, extend search for cursor position to end of row.
14230 (find_row_edges): If the row ends in a newline from a display
14231 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14232 Handle the case of a display string with multiple newlines.
14233 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14234 non-empty line. Fixes confusing cursor motion with arrow keys at
14235 the beginning of a line that starts with whitespace.
14237 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14239 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14242 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14244 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14245 boolean (Bug#9154).
14247 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14249 * xdisp.c (display_line): Record maximum and minimum buffer
14250 positions even if no glyphs were produced (e.g., by a zero-width
14251 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14252 buffer positions that will be removed from the glyph row because
14254 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14255 column is beyond frame width: don't subtract 1 "pixel" when
14256 computing width of the stretch.
14257 (reseat_at_next_visible_line_start): Undo the change made on
14258 2011-09-17 that saved paragraph information and restored it after
14259 the call to `reseat'. (Bug#9545)
14261 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14263 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14264 and turn window cursor on if cleared (Bug#9415).
14266 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14268 * search.c (boyer_moore): Take unibyte characters from pattern
14269 literally. (Bug#9458)
14271 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14273 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14275 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14277 Fix minor problem found by static checking.
14278 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14279 initialized, to pacify gcc -Wuninitialized.
14281 * fileio.c: Report proper errno when syscall falls.
14282 (Finsert_file_contents): Save and restore errno,
14283 so that report_file_error outputs the correct diagnostic.
14284 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14286 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14288 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14290 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14292 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14293 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14295 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14297 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14298 about the current paragraph and restore it after the call to reseat.
14300 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14301 (bidi_find_paragraph_start): Search back for paragraph beginning
14302 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14303 (bidi_move_to_visually_next): Only trigger paragraph-related
14304 computations when the last character is a newline or at EOB, not
14305 just any NEUTRAL_B. (Bug#9470)
14307 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14308 truncated lines if point is covered by a display string. (Bug#9524)
14310 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14312 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14313 (cons_to_x_long): New function.
14314 (lisp_data_to_selection_data): Use it. Correct the test for
14315 short-versus-long data; it was negated. Break out of vector
14316 loop, for efficiency, when a long datum is discovered.
14318 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14320 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14322 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14324 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14325 GCC PR/17406) by declaring this function with external scope.
14327 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14329 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14330 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14332 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14334 * editfns.c (Fformat): Correctly handle text properties on "%%".
14336 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14338 * xterm.c (x_draw_composite_glyph_string_foreground):
14339 * w32term.c (x_draw_composite_glyph_string_foreground):
14340 * term.c (encode_terminal_code):
14341 * composite.c (composition_update_it, get_composition_id):
14342 * xdisp.c (get_next_display_element)
14343 (fill_composite_glyph_string): Add comments about special meaning
14344 of TAB characters in a composition.
14346 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14348 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14349 This occurs when processing a multibyte format.
14350 Problem reported by Wolfgang Jenker.
14352 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14354 * xdisp.c (try_cursor_movement): Only check for exact match if
14355 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14357 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14359 Remove unused external symbols.
14360 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14361 * xdisp.c (calc_pixel_width_or_height): Now static.
14362 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14363 * indent.c (check_display_width):
14364 * w32term.c: Fix comment to match code.
14365 * xterm.c, xterm.h (x_catching_errors): Remove.
14367 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14369 * xselect.c: Use signed conversions more consistently (Bug#9498).
14370 (selection_data_to_lisp_data): Assume incoming selection data are
14371 signed integers, not unsigned. This is to be consistent with
14372 outgoing selection data, which was modified to use signed integers
14373 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14374 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14375 expects long, not unsigned long.
14377 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14379 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14380 computation of loop end. Reported by Johan Bockgård
14383 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14385 * frame.c (Fother_visible_frames_p): Function deleted.
14387 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14389 * indent.c (compute_motion): Process display vector front to back
14390 rather than the other way around. (Bug#2496)
14392 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14394 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14396 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14398 * minibuf.c (Fread_from_minibuffer): Doc fix.
14400 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14402 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14403 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14405 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14407 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14408 value for non-existent files.
14410 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14412 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14413 set its "size" to -1. This will set the modtime_size field of
14414 the corresponding buffer to -1, which is what
14415 verify-visited-file-modtime expects for files that do not exist.
14418 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14420 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14422 * lisp.h: ... from here. push_key_description is no longer
14423 defined in keyboard.c, so its declaration should not be in
14424 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14425 logically belongs with push_key_description.
14427 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14429 * buffer.h: Include <sys/types.h> instead of <time.h>.
14430 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14431 Problem reported by Herbert J. Skuhra.
14433 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14435 * xml.c (parse_region): Make the parsing work for
14436 non-comment-starting XML files again (bug#9144).
14438 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14440 * image.c (gif_load): Fix calculation of bottom and right corner.
14443 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14445 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14446 redisplay in small windows.
14448 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14450 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14452 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14454 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14455 Operate on live windows only.
14457 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14459 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14461 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14463 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14464 only under bidi iteration.
14466 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14468 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14470 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14472 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14473 Without this fix, the command to link temacs failed due to an
14474 undefined symbol __builtin_isnan. This is because
14475 /usr/include/iso/math_c99.h #defines isnan(x) to
14476 __builtin_isnan(x), but the bundled gcc, which identifies itself
14477 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14479 * floatfns.c (isnan): #undef, and then #define to a clone of
14481 (Fisnan): Always define, since it's always available now.
14482 (syms_of_floatfns): Always define isnan at the Lisp level.
14484 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14486 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14488 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14490 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14491 The previous code assumed that file offsets (off_t values) fit in
14492 EMACS_INT variables, which is not true on typical 32-bit hosts.
14493 The code messed up by falsely reporting buffer overflow in cases
14494 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14495 when "big" contains more than 2**29 bytes, even though this
14496 inserts just one byte and does not overflow the buffer.
14497 (Finsert_file_contents): Store file offsets as off_t
14498 values, not as EMACS_INT values. Check for overflow when
14499 converting between EMACS_INT and off_t. When checking for
14500 buffer overflow or for overlap, take the offsets into account.
14501 Don't use EMACS_INT for small values where int suffices.
14502 When checking for overlap, fix a typo: ZV was used where
14503 ZV_BYTE was intended.
14504 (Fwrite_region): Don't assume off_t fits into 'long'.
14505 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14507 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14509 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14511 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14513 sprintf-related integer and memory overflow issues (Bug#9412).
14515 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14516 (esprintf, exprintf, evxprintf): New functions.
14517 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14518 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14519 (modify_event_symbol): Do not assume that the length of
14520 name_alist_or_stem is safe to alloca and fits in int.
14521 (Fexecute_extended_command): Likewise for function name and binding.
14522 (Frecursion_depth): Wrap around reliably on integer overflow.
14523 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14524 since some callers pass EMACS_INT values.
14525 (Fsingle_key_description): Don't crash if symbol name contains more
14526 than MAX_ALLOCA bytes.
14527 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14528 (get_minibuffer): Arg is now EMACS_INT, not int.
14529 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14530 (esprintf, exprintf, evxprintf): New decls.
14531 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14533 * dbusbind.c (signature_cat): New function.
14534 (xd_signature, Fdbus_register_signal):
14535 Do not overrun buffer; instead, report string overflow.
14537 * dispnew.c (add_window_display_history): Don't overrun buffer.
14538 Truncate instead; this is OK since it's just a log.
14540 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14541 even if the time zone offset is outlandishly large.
14542 Don't mishandle offset == INT_MIN.
14544 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14545 when creating daemon; the previous buffer-overflow check was incorrect.
14547 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14548 which has the guts of the old verror function.
14550 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14551 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14553 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14554 (font_unparse_xlfd): Don't blindly alloca long strings.
14555 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14556 fits in int, when using sprintf. Use single snprintf to count
14557 length of string rather than counting it via multiple sprintfs;
14558 that's simpler and more reliable.
14559 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14560 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14561 sprintf, in case result does not fit in int.
14563 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14564 (fontset_from_font): Print it.
14566 * frame.c (tty_frame_count): Now printmax_t, not int.
14567 (make_terminal_frame, set_term_frame_name): Print it.
14568 (x_report_frame_params): In X, window IDs are unsigned long,
14569 not signed long, so print them as unsigned.
14570 (validate_x_resource_name): Check for implausibly long names,
14571 and don't assume name length fits in 'int'.
14572 (x_get_resource_string): Don't blindly alloca invocation name;
14573 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14576 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14577 (xg_check_special_colors, xg_set_geometry):
14578 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14580 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14581 Use esprintf, not sprintf, in case result does not fit in int.
14583 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14584 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14585 it as a large positive number.
14586 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14587 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14589 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14590 in case result does not fit in int.
14592 * print.c (float_to_string): Detect width overflow more reliably.
14593 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14594 buffer overrun. Don't assume list length fits in 'int'. Treat
14595 print length of 0 as 0, not as infinity; to be consistent with other
14596 uses of print length in this function. Don't overflow print length
14597 index. Don't assume hash table size fits in 'long', or that
14598 vectorlike size fits in 'unsigned long'.
14600 * process.c (make_process): Use printmax_t, not int, to format
14601 process-name gensyms.
14603 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14605 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14606 to avoid potential buffer overrun.
14608 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14609 if X resource line is longer than 512 bytes.
14611 * xfns.c (x_window): Make sprintf buffer a bit bigger
14612 to avoid potential buffer overrun.
14614 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14616 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14618 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14620 Integer overflow fixes for scrolling, etc.
14621 Without these, Emacs silently mishandles large integers sometimes.
14622 For example, "C-u 4294967297 M-x recenter" was treated as if
14623 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14625 * xdisp.c (try_window_id): Check Emacs fixnum range before
14626 converting to 'int'.
14628 * window.c (window_scroll_line_based, Frecenter):
14629 Check that an Emacs fixnum is in range before assigning it to 'int'.
14630 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14631 values converted from Emacs fixnums.
14632 (Frecenter): Don't wrap around a line count if it is out of 'int'
14633 range; instead, treat it as an extreme value.
14634 (Fset_window_configuration, compare_window_configurations):
14635 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14637 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14638 that can exceed INT_MAX. Check that EMACS_INT value is in range
14639 before assigning it to the (possibly-narrower) index.
14640 (match_limit): Don't assume that a fixnum can fit in 'int'.
14642 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14645 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14646 (Fvertical_motion): Don't wrap around LINES values that don't fit
14647 in 'int'. Instead, treat them as extreme values. This is good
14648 enough for windows, which can't have more than INT_MAX lines anyway.
14650 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14652 * Require libxml/parser.h to avoid compilation warning.
14654 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14656 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14657 since this reportedly can destroy thread storage.
14659 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14661 * syntax.c (find_defun_start): Update all cache variables if
14662 exiting early (Bug#9401).
14664 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14666 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14668 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14669 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14670 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14672 * term.c (tty_append_glyph): New function.
14673 (produce_stretch_glyph): Static function and its prototype deleted.
14675 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14678 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14680 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14681 when checking :margin (Bug#9390).
14682 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14683 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14684 so that the name doesn't mislead. All uses changed.
14686 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14688 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14691 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14693 * xdisp.c (move_it_to): Don't bail out early when reaching
14694 position beyond to_charpos, if we are scanning backwards.
14695 (move_it_vertically_backward): When DY == 0, make sure we get to
14696 the first character in the line after the newline.
14698 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14700 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14701 (ccl_driver): Do not generate an out-of-range pointer.
14702 (Fccl_execute_on_string): Remove unnecessary check for
14703 integer overflow, noted by Stefan Monnier in
14704 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14705 Remove a FIXME that didn't need fixing.
14706 Simplify the newly-introduced buffer reallocation code.
14708 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14710 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14712 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14714 Integer and memory overflow issues (Bug#9196).
14716 * doc.c (get_doc_string): Rework so that
14717 get_doc_string_buffer_size is the actual buffer size, rather than
14718 being 1 less than the actual buffer size; this makes xpalloc more
14721 * image.c (x_allocate_bitmap_record, cache_image):
14722 * xselect.c (Fx_register_dnd_atom):
14723 Simplify previous changes by using xpalloc.
14725 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14726 since either will do and ptrdiff_t is convenient with xpalloc.
14728 * charset.c (charset_table_size)
14729 (struct charset_sort_data.priority): Now ptrdiff_t.
14730 (charset_compare): Don't overflow if priorities differ greatly.
14731 (Fsort_charsets): Don't assume list length fits in int.
14732 Check for size-calculation overflow when allocating sort data.
14733 (syms_of_charset): Allocate an initial charset table that is
14734 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14736 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14738 * composite.h (struct composition.glyph_len): Now int, not unsigned.

14743 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14744 with xpalloc. The values are still always <= INT_MAX.

14754 (revalidate_region_cache, know_region_cache, region_cache_forward)
14755 (region_cache_backward, pp_cache):
14756 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14757 so that ptrdiff_t * can be passed to xpalloc.
14758 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14759 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

14774 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14776 Don't update size of array until after memory allocation succeeds,
14777 because xmalloc/xrealloc may not return.
14778 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14779 now that we have proper integer overflow checking.
14780 (record_overlay_string, overlay_strings): Catch overflows when
14781 calculating size of overlay_str_buf.
14783 * callproc.c (Fcall_process): Check for size overflow when
14784 calculating size of args2.
14785 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14786 Normally we prefer signed values, but sticking with ptrdiff_t would
14787 require adding more-complicated checks.
14789 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14790 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14791 Redo buffer-overflow calculations to avoid integer overflow.

14830 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14832 * emacs.c (main): Do not reallocate argv, since there is a null at
14833 the end that can be overwritten, and this way there's no need to
14834 worry about size-calculation overflow.
14835 (sort_args): Check for size-calculation overflow.
14837 * eval.c (init_eval_once, grow_specpdl): Don't update size until

14844 (x_set_alpha): Do not assume XINT fits in int.
14846 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14847 This is for the members text_lines, text_cols, total_lines, total_cols,
14848 where the system imposes an 'int' limit.
14850 * fringe.c (Fdefine_fringe_bitmap):
14851 Don't update size until alloc works.

14856 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14857 Check for size-calculation overflow.
14858 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14859 do, as we prefer signed integers.

14866 * gtkutil.h: Change prototypes to match the above.
14868 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

14915 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14916 for command line length. Do not attempt to address one before the
14917 beginning of an array, as that's not portable.

14964 (X_LONG_MIN): New macros.
14965 Use them to make the following changes clearer.
14966 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

14969 (SELECTION_QUANTUM): Remove, replacing with ...
14970 (selection_quantum): ... new function, which avoids overflow.
14972 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

14990 Don't store size until memory allocation succeeds.
14991 (x_get_window_property): Plug memory leak on memory exhaustion.
14992 Don't double-block input; malloc is safe here. Don't assume 2**34
14993 - 4 fits in unsigned long. Add an xassert to check
14994 XGetWindowProperty overflow. Be more careful about overflow
14995 calculations, and distinguish size from memory overflow better.
14996 (receive_incremental_selection): When tracing, don't assume
14997 unsigned int is less than INT_MAX.
14998 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

15001 in the range -65535 through -1 fit in an X unsigned short.
15002 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15003 result parameters unless successful. Rely on cons_to_unsigned
15004 to report problems with elements; the old code wasn't right anyway.
15005 (x_check_property_data): Check for int overflow; we cannot use
15006 a wider type due to X limits.

15039 * lisp.h (hash_lookup, hash_put):
15040 * minibuf.c (Ftest_completion):
15041 Use ptrdiff_t for hash table indexes, not int (which is too
15042 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

15054 with outlandish widths.
15055 * character.h (sanitize_tab_width): Rename from sanitize_width,

15081 (make_lispy_movement): Use same integer type in forward decl
15082 that is used in the definition.

15084 Change bufsize argument back to int, undoing my 2011-03-30 change.
15085 We prefer signed types, and int is wide enough here.
15086 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15087 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15088 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15089 length, not size_t. Use ptrdiff_t for index, not int.
15090 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15091 possibility of integer overflow.

15119 Prefer int to unsigned where either will do.
15120 (tiff_handler): New function, combining the cores of the
15121 old tiff_error_handler and tiff_warning_handler.
15122 This function is rewritten to use vsnprintf and thereby avoid
15123 stack buffer overflows. It uses only the features of vsnprintf
15124 that are common to both POSIX and native Microsoft.
15125 (tiff_error_handler, tiff_warning_handler): Use it.
15126 (tiff_load, gif_load, imagemagick_load_image):
15127 Don't assume :index value fits in 'int'.

15130 the integer types that MagickCropImage accepts. Don't assume
15131 Vimagemagick_render_type has a nonnegative value. Don't assume

15169 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15170 buffers, return left-to-right.
15171 (set_cursor_from_row): Consider candidate row a win if its glyph
15172 represents a newline and point is on that newline. Fixes cursor
15173 positioning on the newline at EOL of R2L text within L2R
15174 paragraph, and vice versa.
15175 (try_cursor_movement): Check continued rows, in addition to
15176 continuation rows. Fixes unwarranted scroll when point enters a
15177 continued line of R2L text within an L2R paragraph, or vice versa.
15178 (cursor_row_p): Consider the case of point being equal to
15179 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

15203 2011-08-23 Eli Zaretskii <eliz@gnu.org>
15205 * xdisp.c (redisplay_window): When computing centering_position,
15206 account for the height of the header line. (Bug#8874)
15208 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15209 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15210 candidate is selected by the mouse, and that candidate has a
15211 composed character under the mouse.
15213 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15214 coordinates reported by pos-visible-in-window-p for a composed
15215 character in column zero.
15217 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

15221 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15223 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15224 consider it a hit if to_charpos is anywhere in the range of the
15225 composed buffer positions.
15227 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15229 * image.c (gif_load): Don't assume that each subimage has the same
15230 dimensions as the base image. Handle disposal method that is
15231 "undefined" by the gif spec (Bug#9335).
15233 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15235 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
15236 (Fcondition_case): Document `debug' symbol in error handler.
15238 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15240 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15241 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15242 from an Org mode buffer to a Speedbar frame.
15244 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15245 a composition, take its buffer position from IT->cmp_it.charpos.
15246 Fixes cursor positioning at the beginning of a line that begins
15247 with a composed character.
15249 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15251 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15252 character bidirectional type, use STRONG_L instead. Fixes crashes
15253 in a buffer produced by `describe-categories'.
15255 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15256 members before the level stack, so they would be saved and
15257 restored when copying iterator state. Fixes incorrect reordering
15258 around TABs covered by display properties.
15260 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15262 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
15264 2011-08-17 Chong Yidong <cyd@stupidchicken.com>

15267 (internal_condition_case_2, internal_condition_case_n):
15268 Remove unnecessary aborts (Bug#9081).
15270 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15272 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15273 has no `load' handler, try opening the file locally. (Bug#9311)
15275 2011-08-16 Ken Brown <kbrown@cornell.edu>
15277 * gmalloc.c: Expand comment.
15279 2011-08-16 Eli Zaretskii <eliz@gnu.org>

15330 2011-08-14 Eli Zaretskii <eliz@gnu.org>
15332 * xdisp.c (move_it_in_display_line_to): Don't invoke
15333 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15334 ppos_it. Fixes vertical cursor motion when line beginning is
15335 covered by an image. (Bug#9296)
15337 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15339 * nsterm.h (ns_run_ascript): Declare.

15344 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15345 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15346 the event loop. Get status from as_status (Bug#7276).
15348 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15349 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15350 the event loop (Bug#7276).
15352 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
15354 * gnutls.c (QCgnutls_bootprop_priority)

15376 (Fnetwork_interface_list): Allocate in increments of bytes instead
15377 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15378 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15380 (struct ifflag_def): notrailers is smart on OSX.
15381 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15382 Get hardware address with getifaddrs if available.
15384 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15386 * xdisp.c (iterate_out_of_display_property): xassert that
15387 IT->position is set to within IT->object's boundaries. Break from
15388 the loop as soon as EOB is reached; avoids infloops in redisplay
15389 when IT->position is set up wrongly due to some bug.
15390 Set IT->current to match the bidi iterator unconditionally.
15391 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15392 entry. Force push_it to save on the stack the current
15393 buffer/string position, to be restored by pop_it. Fix flags in
15394 the iterator structure wrt the object coming from a display
15395 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15396 properties. (Bug#9284)
15398 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15400 * fontset.c (fontset_get_font_group): Add proper type checks.

15432 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15433 to show the arg `TIME' instead of `TIMEVAL'.
15435 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15437 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15438 display property strides EOL and includes a newline, as in
15439 longlines-mode. (Bug#9254)
15440 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15441 word-wrap under bidirectional display. (Bug#9224)
15443 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15444 is non-zero, even if the data buffer is NULL. Fixes a crash in
15445 vertical-motion with longlines-mode. (Bug#9254)
15447 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15449 * bidi.c <bidi_cache_total_alloc>: Now static.

15452 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15455 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15456 amount allocated this far in `bidi_cache_total_alloc'.
15457 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15458 non-zero, only free the data buffer without restoring the cache
15459 contents. All callers changed.
15461 * dispextern.h (bidi_unshelve_cache): Update prototype.
15463 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15464 (move_it_in_display_line, move_it_to)
15465 (move_it_vertically_backward, move_it_by_lines): Replace the call
15466 to xfree to an equivalent call to bidi_unshelve_cache.
15467 (move_it_in_display_line_to): Fix logic of returning
15468 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)

15524 DISP_PROP_P, and pass it to compute_display_string_pos.
15525 Only handle text covered by a display string if DISP_PROP_P is returned
15526 non-zero. All callers of bidi_fetch_char changed.
15528 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>

15614 'malloc' might be invoked reentrantly.
15616 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15617 In other words, assume that every image size is allowed, on non-X
15618 hosts. This assumption is probably wrong, but it lets Emacs compile.

15630 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15632 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15634 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15636 Integer signedness and overflow and related fixes. (Bug#9079)
15638 * bidi.c: Integer size and overflow fixes.
15639 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15640 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15641 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15642 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15643 (bidi_find_other_level_edge):
15644 Use ptrdiff_t instead of EMACS_INT where either will do.
15645 This works better on 32-bit hosts configured --with-wide-int.
15646 (bidi_cache_ensure_space): Check for size-calculation overflow.
15647 Use % rather than repeated addition, for better worst-case speed.
15648 Don't set bidi_cache_size until after xrealloc returns, because it
15650 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15651 (bidi_cache_ensure_space): Also check that the bidi cache size
15652 does not exceed that of the largest Lisp string or buffer. See Eli
15653 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15655 * alloc.c (__malloc_size_t): Remove.
15656 All uses replaced by size_t. See Andreas Schwab's note
15657 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15659 * image.c: Improve checking for integer overflow.
15660 (check_image_size): Assume that f is nonnull, since
15661 it is always nonnull in practice. This is one less thing to
15662 worry about when checking for integer overflow later.
15663 (x_check_image_size): New function, which checks for integer
15664 overflow issues inside X.
15665 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15666 This removes the need for a memory_full check.
15667 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15668 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15669 (xbm_read_bitmap_data): Change locals back to 'int', since
15670 their values must fit in 'int'.
15671 (xpm_load_image, png_load, tiff_load):
15672 Invoke x_create_x_image_and_pixmap earlier,
15673 to avoid much needless work if the image is too large.
15674 (tiff_load): Treat overly large images as if
15675 x_create_x_image_and_pixmap failed, not as malloc failures.
15676 (gs_load): Use x_check_image_size.
15678 * gtkutil.c: Omit integer casts.
15679 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15680 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15682 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15684 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15685 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15686 would wrongly return t on a 64-bit host.
15688 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15689 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15690 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15691 and therefore cause GCC to emit a bogus diagnostic in some cases.
15693 * image.c: Integer signedness and overflow and related fixes.
15694 This is not an exhaustive set of fixes, but it's time to
15695 record what I've got.
15696 (lookup_pixel_color, check_image_size): Remove redundant decls.
15697 (check_image_size): Don't assume that arbitrary EMACS_INT values
15698 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15699 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15700 (tiff_load, imagemagick_load_image):
15701 Check for overflow in size calculations.
15702 (x_create_x_image_and_pixmap): Remove unnecessary test for
15703 xmalloc returning NULL; that can't happen.
15704 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15705 (xpm_color_bucket): Use better integer hashing function.
15706 (xpm_cache_color): Don't possibly over-allocate memory.
15707 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15708 (gif_memory_source):
15709 Use ptrdiff_t, not int or size_t, to record sizes.
15710 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15711 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15712 either works, as we prefer signed integers.
15713 (tiff_read_from_memory, tiff_write_from_memory):
15714 Return tsize_t, not size_t, since that's what the TIFF API wants.
15715 (tiff_read_from_memory): Don't fail simply because the read would
15716 go past EOF; instead, return a short read.
15717 (tiff_load): Omit no-longer-needed casts.
15718 (Fimagemagick_types): Don't assume size fits into 'int'.
15720 Improve hashing quality when configured --with-wide-int.
15721 * fns.c (hash_string): New function, taken from sxhash_string.
15722 Do not discard information about ASCII character case; this
15723 discarding is no longer needed.
15724 (sxhash-string): Use it. Change sig to match it. Caller changed.
15725 * lisp.h: Declare it.
15726 * lread.c (hash_string): Remove, since we now use fns.c's version.
15727 The fns.c version returns a wider integer if --with-wide-int is
15728 specified, so this should help the quality of the hashing a bit.
15730 * emacs.c: Integer overflow minor fix.
15731 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15732 Define only if GNU_LINUX.
15733 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15735 * dispnew.c: Integer signedness and overflow fixes.
15736 Remove unnecessary forward decls, that were a maintenance hassle.
15737 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15739 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15740 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15741 (prepare_desired_row, line_draw_cost):
15742 Use int, not unsigned, where either works.
15743 (save_current_matrix, restore_current_matrix):
15744 Use ptrdiff_t, not size_t, where either works.
15745 (init_display): Check for overflow more accurately, and without
15746 relying on undefined behavior.
15748 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15749 Remove, replacing with the new symbols in lisp.h. All uses changed.
15750 * fileio.c (make_temp_name):
15751 * filelock.c (lock_file_1, lock_file):
15752 * xdisp.c (message_dolog):
15753 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15754 Use pMd etc. instead.
15755 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15756 replacing the pWIDE etc. symbols removed from editfns.c.
15758 * keyboard.h (num_input_events): Now uintmax_t.
15759 This is (very slightly) less likely to mess up due to wraparound.
15762 * buffer.c: Integer signedness fixes.
15763 (alloc_buffer_text, enlarge_buffer_text):
15764 Use ptrdiff_t rather than size_t when either will do, as we prefer
15767 * alloc.c: Integer signedness and overflow fixes.
15768 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15769 (__malloc_size_t): Default to size_t, not to int.
15770 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15771 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15772 Prefer ptrdiff_t to size_t when either would do, as we prefer
15774 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15775 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15776 Now const. Initialize with values that are in range even if char
15778 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15779 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15780 These functions do the right thing with sizes > 2**32.
15781 (check_depth): Now ptrdiff_t, not int.
15782 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15783 Adjust to new way of storing sizes. Check for size overflow bugs
15785 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15786 slightly wrong anyway, as it missed one instance of
15787 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15788 (refill_memory_reserve): Omit needless cast to size_t.
15789 (mark_object_loop_halt): Mark as externally visible.
15791 * xselect.c: Integer signedness and overflow fixes.
15792 (Fx_register_dnd_atom, x_handle_dnd_message):
15793 Use ptrdiff_t, not size_t, since we prefer signed.
15794 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15795 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15796 x_dnd_atoms_size and x_dnd_atoms_length.
15798 * doprnt.c: Prefer signed to unsigned when either works.
15800 * doprnt.c (doprnt):
15802 * xdisp.c (vmessage):
15803 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15804 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15805 prefer signed arithmetic to avoid comparison confusion.
15806 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15807 but is a bit tricky.
15809 Assume freestanding C89 headers, string.h, stdlib.h.
15810 * data.c, doprnt.c, floatfns.c, print.c:
15811 Include float.h unconditionally.
15812 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15813 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15814 * regex.c: Likewise for stddef.h, string.h.
15815 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15816 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15817 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15818 (STDC_HEADERS): Remove obsolete defines.
15819 * sysdep.c: Include limits.h unconditionally.
15821 Assume support for memcmp, memcpy, memmove, memset.
15822 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15823 * regex.c (memcmp, memcpy):
15824 Remove; we assume C89 now.
15826 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15827 (__malloc_safe_bcopy): Remove; no longer needed.
15829 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15830 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15831 well either way, and we prefer signed to unsigned.
15833 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15835 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15836 closes the connection while we're reading (bug#9182).
15838 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15840 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15841 are specified (Bug#9168).
15843 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15845 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15846 Found by GCC static checking and --with-wide-int on a 32-bit host.
15848 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15850 * xdisp.c (compute_display_string_pos): Fix logic of caching
15851 previous display string position. Initialize cached_prev_pos to
15852 -1. Fixes slow-down at the beginning of a buffer.
15854 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15856 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15857 for attrs[LFACE_FONTSET_INDEX].
15859 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15861 * xml.c (parse_region): Remove unused local
15862 that was recently introduced.
15864 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15866 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15867 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15869 * xdisp.c (move_it_in_display_line_to): Record the best matching
15870 position for TO_CHARPOS while scanning the line, and restore it on
15871 exit if none of the characters scanned was an exact match.
15872 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15873 when exact match is impossible due to invisible text, and the
15874 lines are truncated.
15876 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15878 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15881 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15883 Fix a significant slow-down of cursor motion with C-n, C-p,
15884 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15885 auto-repeat under bidi redisplay in fontified buffers.
15886 * xdisp.c (compute_stop_pos_backwards): New function.
15887 (next_element_from_buffer): Call compute_stop_pos_backwards to
15888 find a suitable prev_stop when we find ourselves before
15890 (reseat): Don't look for prev_stop, as that could mean a very long
15892 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15893 <cached_disp_overlay_modiff>: Cache for last found display string
15895 (compute_display_string_pos): Return the cached position if asked
15896 about the same buffer in the same area of character positions, and
15897 the buffer wasn't changed since the time the display string
15898 position was cached.
15900 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15902 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15903 is an integer, which is important for empty lines. (Bug#9149)
15905 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15907 * frame.c (Fmodify_frame_parameters): In tty case, update the
15908 default face if necessary (Bug#4238).
15910 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15912 * editfns.c (Fstring_to_char): No need to explain what a character
15913 is in the docstring (Bug#6576).
15915 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15917 * xml.c (parse_region): Make sure we always return a tree.
15919 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15921 * xml.c (parse_region): If a document contains only comments,
15924 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15926 * xml.c (make_dom): Return comments, too.
15928 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15931 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15932 and the surrounding thread.
15933 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15934 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15935 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15937 * s/openbsd.h (BROKEN_SIGIO): Define.
15938 * unexelf.c (unexec) [__OpenBSD__]:
15939 Don't update the .mdebug section of the Alpha COFF symbol table.
15941 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15943 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15946 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15948 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15949 This fixes some race conditions on the permissions of any newly
15952 * alloc.c (valid_pointer_p): Use pipe, not open.
15953 This fixes some permissions issues when debugging.
15955 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15956 If fchown fails to set both uid and gid, try to set just gid,
15957 as that is sometimes allowed. Adjust the file's mode to eliminate
15958 setuid or setgid bits that are inappropriate if fchown fails.
15960 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15962 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15963 to compare Lisp_Objects.
15964 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15965 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15966 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15968 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15970 * lread.c (read_integer): Unread even EOF character.
15971 (read1): Likewise. Properly record start position of symbol.
15973 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15974 symbol character follows.
15976 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15978 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15979 This works around a problem with the previous change to Fcopy_file.
15980 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15981 and without this change, GCC might complain about discarding
15982 fchown's return value.
15984 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15986 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15988 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15990 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15992 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15994 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15995 it's used from the C level.
15997 * process.c: Use the same condition for POLL_FOR_INPUT in both
15998 keyboard.c and process.c (bug#1858).
16000 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16002 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16003 (Fgnutls_boot): Use it.
16005 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16007 * doc.c (Fsubstitute_command_keys): Revert last change.
16009 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16011 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16012 quotes the next character, and doesn't affect other longer
16013 sequences (bug#8935).
16015 * lread.c (syms_of_lread): Clarify that is isn't only
16016 `eval-buffer' and `eval-defun' that's affected by
16017 `lexical-binding' (bug#8460).
16019 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16021 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16022 bidi redisplay when a line includes both an image and is truncated.
16024 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16026 Fix minor problems found by static checking.
16027 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16028 (elsz): Now a signed constant, not a size_t var. We prefer signed
16029 types to unsigned, to avoid integer comparison confusion. Without
16030 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16031 "cannot optimize loop, the loop counter may overflow", a symptom
16033 * indent.c (Fvertical_motion): Mark locals as initialized.
16034 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16036 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16038 * search.c (Fre_search_backward): Mention `case-fold-search' in
16039 all the re_search_* functions (bug#8138).
16041 * keyboard.c (Fopen_dribble_file): Document when the file is
16044 2011-07-14 Eli Zaretskii <eliz@gnu.org>
16046 * bidi.c (bidi_dump_cached_states): Fix format of displaying
16049 Support bidi reordering of display and overlay strings.
16050 * xdisp.c (compute_display_string_pos)
16051 (compute_display_string_end): Accept additional argument STRING.
16052 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
16053 (reseat_to_string): Initialize bidi_it->string.s and
16054 bidi_it->string.schars.
16055 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
16056 NULL (avoids a crash in bidi_paragraph_init).
16057 Initialize itb.string.lstring.
16058 (init_iterator): Call bidi_init_it only of a valid
16059 buffer position was specified. Initialize paragraph_embedding to
16061 (reseat_to_string): Initialize the bidi iterator.
16062 (display_string): If we need to ignore text properties of
16063 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16064 original value of -1 will not work with bidi.)
16065 (compute_display_string_pos): First arg is now struct
16066 `text_pos *'; all callers changed. Support display properties on
16068 (compute_display_string_end): Support display properties on Lisp
16070 (init_iterator, reseat_1, reseat_to_string): Initialize the

16557 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
16558 (clone_per_buffer_values): Don't assume that

16560 This isn't true in general, and it's particularly not true
16561 if Emacs is configured with --with-wide-int.
16562 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16563 New macros, used in the buffer.c change.

16599 Random fixes. E.g., (random) never returned negative values.
16600 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16601 subseconds part to the entropy, as that's a bit more random.
16602 Prefer signed to unsigned, since the signedness doesn't matter and
16603 in general we prefer signed. When given a limit, use a
16604 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16605 latter isn't right if USE_2_TAGS_FOR_INTS.
16606 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16607 not 0..VALMASK. Don't discard "excess" bits that random () returns.
16609 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
16611 * textprop.c (text_property_stickiness):
16612 Obey Vtext_property_default_nonsticky.

16619 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16620 This is more efficient than Ffile_directory_p and avoids a minor race.
16622 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16624 * buffer.c (Foverlay_put): Say what the return value is
16627 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16628 is a directory before asking whether to use the file name
16630 (barf_or_query_if_file_exists): Make the "File is a directory"
16631 error be more correct.
16633 * fns.c (Frequire): Remove the mention of the .gz files, since
16634 that's installation-specific, but keep the mention of
16635 `get-load-suffixes'.

16639 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

16647 Qgnutls_bootprop_verify_error (which is no longer used).
16649 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16650 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16651 Also (re)move comments that are misplaced or no longer relevant.
16653 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16655 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

16714 (syms_of_keymap): Defsubr make-composed-keymap.
16715 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

16752 * eval.c (struct backtrace): Simplify and port the data structure.
16753 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16754 signed bit field, as this assumption is not portable and it makes
16755 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16756 "char debug_on_exit : 1" as this is not portable either; instead,
16757 use the portable "unsigned int debug_on_exit : 1". Remove unused
16758 member evalargs. Remove obsolete comments about cc bombing out.
16760 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16946 to improve quality of diagnostics for out-of-range radices.
16947 Calculate buffer size correctly for out-of-range radices.
16948 (read1): Check for integer overflow in radices, and in
16949 read-circle numbers.
16950 (read_escape): Avoid int overflow.
16951 (Fload, openp, read_buffer_size, read1)
16952 (substitute_object_recurse, read_vector, read_list, map_obarray):
16953 Use ptrdiff_t, not int, for sizes.
16954 (read1): Use EMACS_INT, not int, for sizes.
16955 Check for size overflow.
16957 * image.c (cache_image): Check for size arithmetic overflow.

16962 Now ptrdiff_t, not int.
16963 (read1): Don't assume doc string length fits in int. Check for
16964 out-of-range doc string lengths.
16965 (read_list): Don't assume file position fits in int.
16966 (read_escape): Check for hex character overflow.
16968 2011-06-22 Leo Liu <sdl.web@gmail.com>
16970 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16971 Move to minibuffer.el.
16973 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16975 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16976 The following patches are for when GLYPH_DEBUG && !XASSERT.
16977 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16978 * dispnew.c (flush_stdout):
16979 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16980 Mark as externally visible.
16981 * dispnew.c (check_window_matrix_pointers): Now static.
16982 * dispnew.c (window_to_frame_vpos):
16983 * xfns.c (unwind_create_frame):
16984 * xterm.c (x_check_font): Remove unused local.
16985 * scroll.c (CHECK_BOUNDS):
16986 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16987 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16988 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16989 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16990 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16992 (debug_method_add): Use va_list and vsprintf rather than relying
16993 on undefined behavior with wrong number of arguments.
16994 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16995 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16996 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16997 since we're not interested in debugging glyphs with old libraries.
16998 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16999 GCC 4.6.0's static checking.
17001 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17003 Integer overflow and signedness fixes (Bug#8873).

17017 * xfaces.c (load_pixmap):
17018 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17019 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17020 (.bitmaps_last, struct x_output.icon_bitmap):
17021 Use ptrdiff_t, not int, for bitmap indexes.
17022 (x_allocate_bitmap_record): Check for size overflow.
17023 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17025 Use ptrdiff_t, not int, for overlay counts.
17026 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17027 * editfns.c (overlays_around, get_pos_property):
17028 * textprop.c (get_char_property_and_overlay):
17029 * xdisp.c (next_overlay_change, note_mouse_highlight):
17030 * xfaces.c (face_at_buffer_position):
17031 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17032 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17033 (Fnext_overlay_change, Fprevious_overlay_change)
17034 (mouse_face_overlay_overlaps, Foverlays_in):
17035 Use ptrdiff_t, not int, for sizes.
17036 (overlays_at, overlays_in): Check for size-calculation overflow.
17038 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17040 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17041 (x_session_initialize): Do not assume string length fits in int.
17043 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17044 This is unlikely, but can occur if DPI is outlandish.
17046 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17047 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17049 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17050 * xrdb.c (magic_file_p, search_magic_path):
17051 Omit last arg SUFFIX; it was always 0. All callers changed.
17052 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17054 * xfont.c (xfont_match): Avoid need for strlen.
17056 * xfns.c: Don't assume strlen fits in int.

17059 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17060 not unsigned long, as we prefer signed integers. All callers changed.
17061 Detect integer overflow in repeat count.
17062 (message_dolog): Don't assume print length fits in 39 bytes.
17063 (display_mode_element): Don't assume strlen fits in int.
17065 * termcap.c: Don't assume sizes fit in int and never overflow.
17066 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17067 (gobble_line): Check for size-calculation overflow.
17069 * minibuf.c (Fread_buffer):
17070 * lread.c (intern, intern_c_string):
17071 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17072 Don't assume string length fits in int.
17074 * keyboard.c (parse_tool_bar_item):
17075 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17077 * font.c: Don't assume string length fits in int.
17078 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17079 Use ptrdiff_t, not int.
17080 (font_intern_prop): Don't assume string length fits in int.
17081 Don't assume integer property fits in fixnum.
17082 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17084 * filelock.c: Fix some buffer overrun and integer overflow issues.
17085 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17086 Reformulate so as not to need the command string.
17087 Invoke gzip -cd rather than gunzip, as it's more portable.
17088 (lock_info_type, lock_file_1, lock_file):
17089 Don't assume pid_t and time_t fit in unsigned long.
17090 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17091 (current_lock_owner): Prefer signed type for sizes.
17092 Use memcpy, not strncpy, where memcpy is what is really wanted.
17093 Don't assume (via atoi) that time_t and pid_t fit in int.
17094 Check for time_t and/or pid_t out of range, e.g., via a network share.
17095 Don't alloca where an auto var works fine.
17097 * fileio.c: Fix some integer overflow issues.
17098 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17099 Don't assume string length fits in int.
17100 (directory_file_name): Don't assume string length fits in long.
17101 (make_temp_name): Don't assume pid fits in int, or that its print
17102 length is less than 20.
17104 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17106 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17108 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17110 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17111 We prefer signed integers, even for size calculations.
17113 * emacs.c: Don't assume string length fits in 'int'.
17114 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17115 (main): Don't invoke strlen when not needed.
17117 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17118 (XD_DEBUG_MESSAGE): Don't waste a byte.
17120 * callproc.c (getenv_internal_1, getenv_internal)
17121 (Fgetenv_internal):
17122 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17124 * lread.c (invalid_syntax): Omit length argument.
17125 All uses changed. This doesn't fix a bug, but it simplifies the
17126 code away from its former Hollerith-constant appearance, and it's
17127 one less 'int' to worry about when looking at integer-overflow issues.
17128 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17130 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17131 This didn't break anything, but it didn't help either.
17132 It's confusing to put a bogus integer in a place where the actual
17133 value does not matter.
17134 (LIST_END_P): Remove unused macro and its bogus comment.
17135 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17137 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17138 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17140 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17141 We prefer signed types, and the value cannot exceed the EMACS_INT
17142 range anyway (because otherwise the length would not be representable).
17143 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17144 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17145 This avoids a GCC warning when WIDE_EMACS_INT.
17147 * indent.c (sane_tab_width): New function.
17148 (current_column, scan_for_column, Findent_to, position_indentation)
17149 (compute_motion): Use it. This is just for clarity.
17150 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17152 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17154 * lisp.h (lint_assume): New macro.
17155 * composite.c (composition_gstring_put_cache):
17156 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17158 * editfns.c, insdel.c:
17159 Omit unnecessary forward decls, to simplify future changes.
17161 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17163 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17165 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17166 Use much-faster test for byte-length change.
17167 Don't assume string byte-length fits in 'int'.
17168 Check that character arg fits in 'int'.
17169 (mapcar1): Declare byte as byte, for clarity.
17171 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17173 * fns.c (concat): Catch string overflow earlier.
17174 Do not rely on integer wraparound.
17176 * dispextern.h (struct it.overlay_strings_charpos)
17177 (struct it.selective): Now EMACS_INT, not int.
17178 * xdisp.c (forward_to_next_line_start)
17179 (back_to_previous_visible_line_start)
17180 (reseat_at_next_visible_line_start, next_element_from_buffer):
17181 Don't arbitrarily truncate the value of 'selective' to int.
17183 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17185 * composite.c: Don't truncate sizes to 'int'.
17186 (composition_gstring_p, composition_reseat_it)
17187 (composition_adjust_point): Use EMACS_INT, not int.
17188 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17189 not EMACS_UINT, for indexes.
17191 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17193 * buffer.c: Include <verify.h>.
17194 (struct sortvec.priority, struct sortstr.priority):
17195 Now EMACS_INT, not int.
17196 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17197 (struct sortstr.size, record_overlay_string)
17198 (struct sortstrlist.size, struct sortlist.used):
17199 Don't truncate size to int.
17200 (record_overlay_string): Check for size-calculation overflow.
17201 (init_buffer_once): Check at compile-time, not run-time.
17203 2011-06-22 Jim Meyering <meyering@redhat.com>
17205 Don't leak an XBM-image-sized buffer
17206 * image.c (xbm_load): Free the image buffer after using it.
17208 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17211 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17212 that Sun C diagnosed.
17213 * fns.c (secure_hash): Fix pointer signedness issue.
17214 * intervals.c (static_offset_intervals): New function.
17215 (offset_intervals): Use it.
17217 2011-06-21 Leo Liu <sdl.web@gmail.com>
17220 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17223 * fns.c (secure_hash): Rename from crypto_hash_function and change
17224 the first arg to accept symbols.
17225 (Fsecure_hash): New primitive.
17226 (syms_of_fns): New symbols.
17228 2011-06-20 Deniz Dogan <deniz@dogan.se>
17230 * process.c (Fset_process_buffer): Clarify return value in
17233 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17235 * dispnew.c (add_window_display_history): Use BVAR.
17237 * xdisp.c (debug_method_add): Use BVAR.
17238 (check_window_end, dump_glyph_matrix, dump_glyph)
17239 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17241 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17244 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17245 check till after the cache is created in init_frame_faces.
17247 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17249 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17251 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17253 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17254 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17255 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17257 Improve buffer-overflow checking (Bug#8873).
17258 * fileio.c (Finsert_file_contents):
17259 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17260 Remove the old (too-loose) buffer overflow checks.
17261 They weren't needed, since make_gap checks for buffer overflow.
17262 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17263 The old code merely checked for Emacs fixnum overflow, and relied
17264 on undefined (wraparound) behavior. The new code avoids undefined
17265 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17267 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17268 Tune. Don't use wider integers than needed. Don't use alloca.
17269 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17271 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17273 * insdel.c, lisp.h (buffer_overflow): New function.
17274 (insert_from_buffer_1, replace_range, replace_range_2):
17275 * insdel.c (make_gap_larger):
17276 * editfns.c (Finsert_char):
17277 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17279 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17281 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17283 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17285 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17286 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17288 * fileio.c: Don't assume EMACS_INT fits in off_t.
17289 (emacs_lseek): New static function.
17290 (Finsert_file_contents, Fwrite_region): Use it.
17291 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17293 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17295 * fns.c: Don't overflow int when computing a list length.
17296 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17297 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17298 truncation on 64-bit hosts. Check for QUIT every
17299 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17300 faster and is responsive enough.
17301 (Flength): Report an error instead of overflowing an integer.
17302 (Fsafe_length): Return a float if the value is not representable
17303 as a fixnum. This shouldn't happen except in contrived situations.
17304 (Fnthcdr, Fsort): Don't assume list length fits in int.
17305 (Fcopy_sequence): Don't assume vector length fits in int.
17307 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17308 (header_size, word_size): New constants.
17309 (allocate_vectorlike): Don't check size overflow here.
17310 (allocate_vector): Check it here instead, since this is the only
17311 caller of allocate_vectorlike that could cause overflow.
17312 Check that the new vector's length is representable as a fixnum.
17314 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17315 The previous code was bogus. For example, next_almost_prime (32)
17316 returned 39, which is undesirable as it is a multiple of 3; and
17317 next_almost_prime (24) returned 25, which is a multiple of 5 so
17318 why was the code bothering to check for multiples of 7?
17320 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17322 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17324 Variadic C functions now count arguments with ptrdiff_t.
17325 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17326 Back then I didn't know that the Emacs coding style prefers signed int.
17327 Also, in the meantime I found a few more instances where arguments
17328 were being counted with int, which may truncate counts on 64-bit
17329 machines, or EMACS_INT, which may be unnecessarily wide.
17330 * lisp.h (struct Lisp_Subr.function.aMANY)
17331 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17332 Arg counts are now ptrdiff_t, not size_t.
17333 All variadic functions and their callers changed accordingly.
17334 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17335 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17336 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17337 * callint.c (Fcall_interactively): Check arg count for overflow,
17338 to avoid potential buffer overrun. Use signed char, not 'int',
17339 for 'varies' array, so that we needn't bother to check its size
17340 calculation for overflow.
17341 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17342 * eval.c (apply_lambda):
17343 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17344 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17345 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17347 * callint.c (Fcall_interactively): Don't use index var as event count.
17349 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17350 * mem-limits.h (SIZE): Remove; no longer used.
17352 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17354 Remove unnecessary casts.
17355 * xterm.c (x_term_init):
17356 * xfns.c (x_set_border_pixel):
17357 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17358 These aren't needed now that we assume ANSI C.
17360 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17361 It's more likely to cause problems (due to unsigned overflow)
17364 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17366 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17368 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17370 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17372 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17374 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17376 GLYPH_CODE_FACE returns EMACS_INT, not int.
17377 * dispextern.h (merge_faces):
17378 * xfaces.c (merge_faces):
17379 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17380 Don't assume EMACS_INT fits in int.
17382 * character.h (CHAR_VALID_P): Remove unused parameter.
17383 * fontset.c, lisp.h, xdisp.c: All uses changed.
17385 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17387 * fns.c (concat): Minor tuning based on overflow analysis.
17388 This doesn't fix any bugs. Use int to hold character, instead
17389 of constantly refetching from Emacs object. Use XFASTINT, not
17390 XINT, for value known to be a character. Don't bother comparing
17391 a single byte to 0400, as it's always less.
17393 * floatfns.c (Fexpt):
17394 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17396 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17399 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17401 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17402 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17403 incorrectly succeed when S was a string, because 4294967386 was
17404 truncated before it was used.
17406 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17407 Otherwise, an out-of-range integer could cause undefined behavior
17410 * composite.c: Use int, not EMACS_INT, for characters.
17411 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17412 EMACS_INT, for values that are known to be in character range.
17413 This doesn't fix any bugs but is the usual style inside Emacs and
17414 may generate better code on 32-bit machines.
17416 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17417 This is for reasons similar to the recent CHAR_STRING fix.
17418 * charset.c (Fencode_char): Check that character arg is actually
17419 a character. Pass an int to ENCODE_CHAR.
17420 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17421 wider than 'int', as a compile-time check to prevent future regressions
17424 * character.c (char_string): Remove unnecessary casts.
17426 Make sure a 64-bit char is never passed to CHAR_STRING.
17427 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17428 by silently ignoring the top 32 bits, allowing some values
17429 that were far too large to be valid characters.
17430 * character.h: Include <verify.h>.
17431 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17432 arguments are no wider than unsigned, as a compile-time check
17433 to prevent future regressions in this area.
17435 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17436 (Fsubst_char_in_region):
17438 * xdisp.c (decode_mode_spec_coding):
17439 Adjust to CHAR_STRING's new requirement.
17440 * editfns.c (Finsert_char, Fsubst_char_in_region):
17441 * fns.c (concat): Check that character args are actually
17442 characters. Without this test, these functions did the wrong
17443 thing with wildly out-of-range values on 64-bit hosts.
17445 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17446 These casts should not be needed on 32-bit hosts, either.
17447 * keyboard.c (read_char):
17448 * lread.c (Fload): Remove casts to unsigned.
17450 * lisp.h (UNSIGNED_CMP): New macro.
17451 This fixes comparison bugs on 64-bit hosts.
17452 (ASCII_CHAR_P): Use it.
17453 * casefiddle.c (casify_object):
17454 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17455 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17456 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17457 * dispextern.h (FACE_FROM_ID):
17458 * keyboard.c (read_char): Use UNSIGNED_CMP.
17460 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17461 not to EMACS_INT, to avoid GCC warning.
17463 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17465 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17466 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17467 isn't needed on 32-bit machines.
17469 * buffer.c (Fgenerate_new_buffer_name):
17470 Use EMACS_INT for count, not int.
17471 (advance_to_char_boundary): Return EMACS_INT, not int.
17473 * data.c (Qcompiled_function): Now static.
17475 * window.c (window_body_lines): Now static.
17477 * image.c (gif_load): Rename local to avoid shadowing.
17479 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17480 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17481 * alloc.c (make_save_value): Integer argument is now of type
17482 ptrdiff_t, not int.
17483 (mark_object): Use ptrdiff_t, not int.
17484 * lisp.h (pD): New macro.
17485 * print.c (print_object): Use it.
17487 * alloc.c: Use EMACS_INT, not int, to count objects.
17488 (total_conses, total_markers, total_symbols, total_vector_size)
17489 (total_free_conses, total_free_markers, total_free_symbols)
17490 (total_free_floats, total_floats, total_free_intervals)
17491 (total_intervals, total_strings, total_free_strings):
17492 Now EMACS_INT, not int. All uses changed.
17493 (Fgarbage_collect): Compute overall total using a double, so that
17494 integer overflow is less likely to be a problem. Check for overflow
17495 when converting back to an integer.
17496 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17497 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17498 These were 'int' variables that could overflow on 64-bit hosts;
17499 they were never used, so remove them instead of repairing them.
17500 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17501 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17502 Previously, this ceilinged at INT_MAX, but that doesn't work on
17504 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17506 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17507 (allocate_vectorlike): Check for ptrdiff_t overflow.
17508 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17509 when a (possibly-narrower) signed value would do just as well.
17510 We prefer using signed arithmetic, to avoid comparison confusion.
17512 * alloc.c: Catch some string size overflows that we were missing.
17513 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17514 for convenience in STRING_BYTES_MAX.
17515 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17516 The definition here is exact; the one in lisp.h was approximate.
17517 (allocate_string_data): Check for string overflow. This catches
17518 some instances we weren't catching before. Also, it catches
17519 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17520 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17521 and ptrdiff_t and EMACS_INT are both 64 bits.
17523 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17524 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17525 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17527 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17529 * alloc.c (Fmake_string): Check for out-of-range init.
17531 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17533 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17535 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17537 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17538 xg_get_default_scrollbar_width.
17540 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17541 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17542 (style_changed_cb): Call update_theme_scrollbar_width and call
17543 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17544 all frames (Bug#8505).
17545 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17546 Call gtk_window_set_resizable if HAVE_GTK3.
17547 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
17548 and height if HAVE_GTK3 (Bug#8505).
17549 (scroll_bar_width_for_theme): New variable.
17550 (update_theme_scrollbar_width): New function.
17551 (xg_get_default_scrollbar_width): Move code to
17552 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

17555 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17557 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17559 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17561 * frame.c (make_frame): Call other_buffer_safely instead of
17564 * window.c (temp_output_buffer_show): Call display_buffer with
17565 second argument Vtemp_buffer_show_specifiers and reset latter
17566 immediately after the call.
17567 (Vtemp_buffer_show_specifiers): New variable.
17568 (auto_window_vscroll_p, next_screen_context_lines)
17569 (Vscroll_preserve_screen_position): Remove leading asterisks from

18120 (display_prop_intangible_p): Reimplement to call
18121 handle_display_spec instead of single_display_spec_intangible_p.
18122 Accept 3 additional arguments needed by handle_display_spec.

18133 value of a `display' property is a "replacing spec".
18134 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18135 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

18163 All callers changed. (Bug#8762)
18165 * gnutls.c: Use Emacs's memory allocators.
18166 Without this change, the gnutls library would invoke malloc etc.
18167 directly, which causes problems on non-SYNC_INPUT hosts, and which
18168 runs afoul of improving memory_full behavior. (Bug#8761)
18169 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18170 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18171 xfree instead of the default malloc, realloc, free.
18172 (Fgnutls_boot): No need to check for memory allocation failure,
18173 since xmalloc does that for us.
18175 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

18196 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18197 * alloc.c (allocate_vectorlike):
18198 Check for overflow in vector size calculations.
18199 * ccl.c (ccl_driver):
18200 Check for overflow when converting EMACS_INT to int.

18202 need to be updated by these changes.
18203 * fns.c (make_hash_table, maybe_resize_hash_table):
18204 Check for integer overflow with large hash tables.
18205 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18206 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18207 (SXHASH_REDUCE): New macro.
18208 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18209 Use it instead of discarding useful hash info with large hash values.
18210 (sxhash_float): New function.
18211 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18212 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18213 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18214 Rewrite to use FIXNUM_BITS, as this simplifies things.
18215 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18216 Adjust signatures to match updated version of code.
18217 (consing_since_gc): Now EMACS_INT, since a single hash table can
18218 use more than INT_MAX bytes.

18246 only when CANNOT_DUMP is defined.
18247 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18249 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18251 * dispnew.c (add_window_display_history): Use const for the string
18252 pointer. Remove declaration, not needed.
18254 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18256 Use 'inline', not 'INLINE'.
18257 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18258 * alloc.c, fontset.c (INLINE): Remove.
18259 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18260 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18261 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18262 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18263 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18265 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18267 Make it possible to run ./temacs.
18269 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18270 syms_of_callproc does the same thing. Remove test for
18271 "initialized", do it in the caller.
18272 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18274 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18276 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18277 (read_minibuf): Use get_minibuffer.
18278 (syms_of_minibuf): Use DEFSYM.
18279 (Qmetadata): New var.
18280 * data.c (Qbuffer): Don't make it static.
18281 (syms_of_data): Use DEFSYM.
18283 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18285 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18286 (CCL_CODE_MIN): New macro.
18288 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18290 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18292 * eval.c (Qdebug): Now static.
18293 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18294 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18295 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18297 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18299 * image.c: Various fixes to ImageMagick code comments.
18300 (Fimagemagick_types): Doc fix.
18302 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18304 Minor fixes prompted by GCC 4.6.0 warnings.
18306 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18308 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18309 (x_clipboard_manager_save_all): Move extern decl to ...
18310 * xterm.h: ... here, so that it can be checked for consistency.
18312 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18314 * xselect.c (x_clipboard_manager_save_frame)
18315 (x_clipboard_manager_save_all): New functions.
18316 (Fx_clipboard_manager_save): Lisp function deleted.
18318 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18319 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18321 * xterm.h: Update prototype.
18323 2011-05-28 William Xu <william.xwl@gmail.com>
18325 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18326 exiting (Bug#8239).
18328 2011-05-28 Jim Meyering <meyering@redhat.com>
18330 Avoid a sign-extension bug in crypto_hash_function.
18331 * fns.c (to_uchar): Define.
18332 (crypto_hash_function): Use it to convert some newly-signed
18333 variables to unsigned, to avoid sign-extension bugs. For example,
18334 without this change, (md5 "truc") would evaluate to
18335 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18336 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18337 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18339 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18341 Integer overflow fixes.
18343 * dbusbind.c: Serial number integer overflow fixes.
18344 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18345 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18346 to hold a serial number that is too large for a fixnum.
18347 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18348 Check for serial numbers out of range. Decode any serial number
18349 that was so large that it became a float. (Bug#8722)
18351 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18352 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18353 Use XFASTINT rather than XUINT when numbers are nonnegative.
18354 (xd_append_arg, Fdbus_method_return_internal):
18355 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18356 arguments, check that Lisp number is nonnegative, rather than
18357 silently wrapping negative numbers around. (Bug#8722)
18358 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18361 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18363 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18365 ccl: Add integer overflow checks.
18366 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18367 (IN_INT_RANGE): New macros.
18368 (ccl_driver): Use them to check for integer overflow when
18369 decoding a CCL program. Many of the new checks are whether XINT (x)
18370 fits in int; it doesn't always, on 64-bit hosts. The new version
18371 doesn't catch all possible integer overflows, but it's an
18372 improvement. (Bug#8719)
18374 * alloc.c (make_event_array): Use XINT, not XUINT.
18375 There's no need for unsigned here.
18377 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18378 This follows up to the 2011-05-06 change that substituted uintptr_t
18379 for EMACS_INT. This case wasn't caught back then.
18381 Rework Fformat to avoid integer overflow issues.
18382 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18383 now (part of C89). Include <verify.h>.
18384 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18385 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18386 (Fformat): Avoid the prepass trying to compute sizes; it was only
18387 approximate and thus did not catch overflow reliably. Instead, walk
18388 through the format just once, formatting and computing sizes as we go,
18389 checking for integer overflow at every step, and allocating a larger
18390 buffer as needed. Keep track separately whether the format is
18391 multibyte. Keep only the most-recently calculated precision, rather
18392 than them all. Record whether each argument has been converted to
18393 string. Use EMACS_INT, not int, for byte and char and arg counts.
18394 Support field widths and precisions larger than INT_MAX. Avoid
18395 sprintf's undefined behavior with conversion specifications such as %#d
18396 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18397 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18398 formatting out-of-range floating point numbers with int
18399 formats. (Bug#8668)
18401 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18403 * data.c: Avoid integer truncation in expressions involving floats.
18404 * data.c: Include <intprops.h>.
18405 (arith_driver): When there's an integer overflow in an expression
18406 involving floating point, convert the integers to floating point
18407 so that the resulting value does not suffer from catastrophic
18408 integer truncation. For example, on a 64-bit host (* 4
18409 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18410 Do not rely on undefined behavior after integer overflow.
18412 merge count_size_as_multibyte, parse_str_to_multibyte
18413 * character.c, character.h (count_size_as_multibyte):
18414 Rename from parse_str_to_multibyte; all uses changed.
18415 Check for integer overflow.
18416 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18417 since it's now a duplicate of the other. This is more of
18418 a character than a buffer op, so better that it's in character.c.
18419 * fns.c, print.c: Adjust to above changes.
18421 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18423 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18425 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18427 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18428 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18429 (x_clipboard_manager_save): Now static.
18430 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18432 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18433 (crypto_hash_function): Now static.
18434 Fix pointer signedness problems. Avoid unnecessary initializations.
18436 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18438 * termhooks.h (Vselection_alist): Make it terminal-local.
18440 * terminal.c (create_terminal): Initialize it.
18442 * xselect.c: Support for clipboard managers.
18443 (Vselection_alist): Move to termhooks.h as terminal-local var.
18444 (LOCAL_SELECTION): New macro.
18445 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18446 (symbol_to_x_atom): Remove gratuitous arg.
18447 (x_handle_selection_request, lisp_data_to_selection_data)
18448 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18449 (x_own_selection, x_get_local_selection, x_convert_selection):
18450 New arg, specifying work frame. Use terminal-local Vselection_alist.
18451 (some_frame_on_display): Delete unused function.
18452 (Fx_own_selection_internal, Fx_get_selection_internal)
18453 (Fx_disown_selection_internal, Fx_selection_owner_p)
18454 (Fx_selection_exists_p): New optional frame arg.
18455 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18456 (x_handle_selection_clear): Don't treat other terminals with the
18457 same keyboard specially. Use the terminal-local Vselection_alist.
18458 (x_clear_frame_selections): Use Frun_hook_with_args.
18460 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18462 * xterm.h: Add support for those atoms.
18464 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18466 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18467 (converted_selections, conversion_fail_tag): New global variables.
18468 (x_selection_request_lisp_error): Free the above.
18469 (x_get_local_selection): Remove unnecessary code.
18470 (x_reply_selection_request): Args changed; handle arbitrary array
18471 of converted selections stored in converted_selections.
18472 Separate the XChangeProperty and SelectionNotify steps.
18473 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18474 (x_convert_selection): New function.
18475 (x_handle_selection_event): Simplify.
18476 (x_get_foreign_selection): Don't ignore incoming requests while
18477 waiting for an answer; this will fail when we implement
18478 SAVE_TARGETS, and seems unnecessary anyway.
18479 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18480 (Vx_sent_selection_functions): Doc fix.
18482 2011-05-26 Leo Liu <sdl.web@gmail.com>
18484 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18486 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18488 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18490 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18491 for fringe update if it has periodic bitmap.
18492 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18493 and fringe_bitmap_periodic_p.
18495 * fringe.c (get_fringe_bitmap_data): New function.
18496 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18497 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18498 row. Mark glyph row for fringe update if periodicity changed.
18500 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18501 for fringe update unless it has periodic bitmap.
18503 2011-05-25 Kenichi Handa <handa@m17n.org>
18505 * xdisp.c (get_next_display_element): Set correct it->face_id for
18506 a static composition.
18508 2011-05-24 Leo Liu <sdl.web@gmail.com>
18511 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18513 * fns.c (crypto_hash_function, Fsha1): New function.
18514 (Fmd5): Use crypto_hash_function.
18515 (syms_of_fns): Add Ssha1.
18517 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18519 * gnutls.c: Remove unused macros.
18520 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18521 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18522 Remove macros that are defined and never used.
18523 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18525 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18527 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18528 (Fx_get_selection_internal): Minor cleanup.
18529 (Fx_own_selection_internal): Rename arguments for consistency with
18532 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18534 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18536 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18538 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18540 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18542 * dispnew.c (scrolling_window): Don't exclude the case that the
18543 last enabled row in the desired matrix touches the bottom boundary.
18545 2011-05-21 Glenn Morris <rgm@gnu.org>
18547 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18548 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18549 and add some more files.
18551 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18553 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18554 report_file_error introduced by the change from 2011-05-07.
18556 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18558 * systime.h (Time): Define only if emacs is defined.
18559 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18560 where the include path doesn't have X11/X.h by default. See
18561 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18563 2011-05-20 Kenichi Handa <handa@m17n.org>
18565 * composite.c (find_automatic_composition): Fix previous change.
18567 2011-05-20 Glenn Morris <rgm@gnu.org>
18569 * lisp.mk: New file, split from Makefile.in.
18570 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18571 (shortlisp): Remove.
18572 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18574 2011-05-19 Glenn Morris <rgm@gnu.org>
18576 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18577 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18578 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18579 (lisp): Set the order to that of loadup.el.
18580 (shortlisp): Make it a copy of $lisp.
18581 (SOME_MACHINE_LISP): Remove.
18582 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18583 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18585 2011-05-18 Kenichi Handa <handa@m17n.org>
18587 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18588 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18589 (find_automatic_composition): Mostly rewrite for efficiency.
18591 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18593 * makefile.w32-in: Update dependencies.
18595 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18597 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18598 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18600 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18602 Fix some integer overflow issues, such as string length overflow.
18604 * insdel.c (count_size_as_multibyte): Check for string overflow.
18606 * character.c (lisp_string_width): Check for string overflow.
18607 Use EMACS_INT, not int, for string indexes and lengths; in
18608 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18609 the resulting string length overflows an EMACS_INT; instead,
18610 report a string overflow if no precision given. When checking for
18611 precision exhaustion, use a check that cannot possibly have
18612 integer overflow. (Bug#8675)
18613 * character.h (lisp_string_width): Adjust to new signature.
18615 * alloc.c (string_overflow): New function.
18616 (Fmake_string): Use it. This doesn't change behavior, but saves
18617 a few bytes and will simplify future changes.
18618 * character.c (string_escape_byte8): Likewise.
18619 * lisp.h (string_overflow): New decl.
18621 Fixups, following up to the user-interface timestamp change.
18622 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18623 for UI timestamps, instead of unsigned long.
18624 * msdos.c (mouse_get_pos): Likewise.
18625 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18626 * w32gui.h (Time): Define by including "systime.h" rather than by
18627 declaring it ourselves. (Bug#8664)
18629 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18630 * image.c (clear_image_cache): Likewise.
18632 * term.c (term_mouse_position): Don't assume time_t wraparound.
18634 Be more systematic about user-interface timestamps.
18635 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18636 and sometimes 'EMACS_UINT', to represent these timestamps.
18637 This change causes it to use 'Time' uniformly, as that's what X uses.
18638 This makes the code easier to follow, and makes it easier to catch
18639 integer overflow bugs such as Bug#8664.
18640 * frame.c (Fmouse_position, Fmouse_pixel_position):
18641 Use Time, not unsigned long, for user-interface timestamps.
18642 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18643 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18644 * keyboard.h (last_event_timestamp): Likewise.
18645 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18646 * menu.h (xmenu_show): Likewise.
18647 * term.c (term_mouse_position): Likewise.
18648 * termhooks.h (struct input_event.timestamp): Likewise.
18649 (struct terminal.mouse_position_hook): Likewise.
18650 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18651 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18652 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18653 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18654 what it was before.
18655 * menu.h, termhooks.h: Include "systime.h", for Time.
18657 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18658 Don't assume that the difference between two unsigned long values
18659 can fit into an integer. At this point, we know button_down_time
18660 <= event->timestamp, so the difference must be nonnegative, so
18661 there's no need to cast the result if double-click-time is
18662 nonnegative, as it should be; check that it's nonnegative, just in
18663 case. This bug is triggered when events are more than 2**31 ms
18664 apart (about 25 days). (Bug#8664)
18666 * xselect.c (last_event_timestamp): Remove duplicate decl.
18667 (x_own_selection): Remove needless cast to unsigned long.
18669 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18670 that always fit in int. Use a sentinel instead of a counter, to
18671 avoid a temp and to allay GCC's concerns about possible int overflow.
18672 * frame.h (struct frame): Use int for menu_bar_items_used
18673 instead of EMACS_INT, since it always fits in int.
18675 * menu.c (grow_menu_items): Check for int overflow.
18677 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18679 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18680 Before, the code was not consistent. These values cannot exceed
18681 2**31 - 1 so there's no need to make them unsigned.
18682 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18683 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18684 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18686 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18688 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18689 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18690 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18691 presumably because the widths might not match.
18693 * window.c (size_window): Avoid needless test at loop start.
18695 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18697 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18699 2011-05-12 Drew Adams <drew.adams@oracle.com>
18701 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18703 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18705 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18706 `width' to `bar_area_x' and `bar_area_width', respectively.
18707 (x_scroll_run): Take account of fringe background extension.
18709 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18710 Rename local vars `left' and `width' to `bar_area_x' and
18711 `bar_area_width', respectively.
18712 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18713 background extension.
18715 2011-05-10 Jim Meyering <meyering@redhat.com>
18717 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18719 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18721 * image.c (Finit_image_library): Return t for built-in image types,
18722 like pbm and xbm. (Bug#8640)
18724 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18726 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18728 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18730 * w32console.c (Fset_screen_color): Doc fix.
18731 (Fget_screen_color): New function.
18732 (syms_of_ntterm): Defsubr it.
18734 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18735 unlink the temporary file if Fcall_process didn't create it in the
18737 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18738 child process will be redirected to a file specified with `:file'.
18739 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18740 cue to call_process_cleanup not to close that handle.
18742 2011-05-07 Ben Key <bkey76@gmail.com>
18744 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18745 one of two shell specific rules, either bootstrap-temacs-CMD or
18746 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18747 to the previous implementation of the bootstrap-temacs rule.
18748 The bootstrap-temacs-CMD rule is similar to the previous
18749 implementation of the bootstrap-temacs rule except that it
18750 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18753 These changes, along with some changes to nt/configure.bat,
18754 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18755 earlier fix to add support for --cflags and --ldflags options
18756 that include quotes so that it works whether make uses cmd or
18759 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18761 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18762 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18764 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18765 a string. Handle both cases.
18766 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18767 (Fdbus_register_method): Use Qinvalid_function.
18769 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18771 * makefile.w32-in: Update dependencies.
18772 (LISP_H): Add inttypes.h and stdin.h.
18773 (PROCESS_H): Add unistd.h.
18775 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18777 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18778 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18780 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18782 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18784 * term.c (vfatal): Remove stray call to va_end.
18785 It's not needed and the C Standard doesn't allow it here anyway.
18787 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18788 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18790 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18793 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18795 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18797 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18799 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18801 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18803 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18804 * charset.c (Fdefine_charset_internal): Don't initialize
18805 charset.code_space[15]. The value was garbage, on hosts with
18806 32-bit int (Bug#8600).
18808 * lread.c (read_integer): Be more consistent with string-to-number.
18809 Use string_to_number to do the actual conversion; this avoids
18810 rounding errors and fixes some other screwups. Without this fix,
18811 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18812 (digit_to_number): Move earlier, for benefit of read_integer.
18813 Return -1 if the digit is out of range for the base, -2 if it is
18814 not a digit in any supported base. (Bug#8602)
18816 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18818 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18819 to match comment at start of function. This also removes a
18820 GCC warning about overflow in a 32+64-bit port.
18822 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18824 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18825 Reported by Stefan Monnier in
18826 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18827 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18828 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18830 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18831 (EMACS_UINTPTR): Likewise, with uintptr_t.
18833 * lisp.h: Prefer 64-bit EMACS_INT if available.
18834 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18835 on 32-bit hosts that have 64-bit int, so that they can access
18837 However, temporarily disable this change unless the temporary
18838 symbol WIDE_EMACS_INT is defined.
18840 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18842 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18843 This removes an assumption that EMACS_INT and long are the same
18844 width as pointers. The assumption is true for Emacs porting targets
18845 now, but we want to make other targets possible.
18846 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18847 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18848 In the rest of the code, change types of integers that hold casted
18849 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18850 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18851 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18852 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18853 No need to cast type when ORing.
18854 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18855 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18856 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18857 assume EMACS_INT is the same width as char *.
18858 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18859 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18860 Remove no-longer-needed casts.
18861 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18862 (xg_tool_bar_help_callback, xg_make_tool_item):
18863 Use EMACS_INTPTR to hold an integer
18864 that will be cast to void *; this can avoid a GCC warning
18865 if EMACS_INT is not the same width as void *.
18866 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18867 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18868 (current_message_1, set_message_1):
18869 Use a local to convert to proper width without a cast.
18870 * xmenu.c (dialog_selection_callback): Likewise.
18872 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18873 Also, don't assume VALBITS / RAND_BITS is less than 5,
18874 and don't rely on undefined behavior when shifting a 1 left into
18876 * lisp.h (get_random): Change signature to match.
18878 * lread.c (hash_string): Use size_t, not int, for hash computation.
18879 Normally we prefer signed values; but hashing is special, because
18880 it's better to use unsigned division on hash table sizes so that
18881 the remainder is nonnegative. Also, size_t is the natural width
18882 for hashing into memory. The previous code used 'int', which doesn't
18883 retain enough info to hash well into very large tables.
18884 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18886 * dbusbind.c: Don't possibly lose pointer info when converting.
18887 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18888 Use XPNTR rather than XHASH, so that the high-order bits of
18889 the pointer aren't lost when converting through void *.
18891 * eval.c (Fautoload): Don't double-shift a pointer.
18893 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18895 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18897 * gnutls.c (DEF_GNUTLS_FN):
18898 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18900 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18902 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18905 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18907 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18908 New version that can reserve upto 2GB of heap space.
18910 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18912 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

18916 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18917 `gnutls_certificate_set_x509_key_file'.
18919 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18921 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18922 Update dependencies.
18924 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18926 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18927 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18928 Remove unused parameter `fildes'.
18929 * process.c (read_process_output, send_process): Don't pass it.
18931 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18933 Fix previous change: the library cache is defined in w32.c.
18934 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18935 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18937 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18939 Implement dynamic loading of GnuTLS on Windows.
18941 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18942 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18943 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18946 * gnutls.c (Qgnutls_dll): Define.
18947 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18948 (gnutls_*): Declare function pointers.
18949 (init_gnutls_functions): New function to initialize function pointers.

18952 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18953 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18954 (emacs_gnutls_write, emacs_gnutls_read)
18955 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18956 (Fgnutls_available_p): New function.
18957 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

18959 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18961 * image.c: Include w32.h.
18962 (Vimage_type_cache): Delete.

18964 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18965 (w32_delayed_load): Move to w32.c.
18967 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18969 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18970 (w32_delayed_load): Move from image.c. When loading a library, record
18971 its filename in the :loaded-from property of the library id.
18972 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18973 Initialize and staticpro them.
18974 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18976 * process.c: Include lisp.h before w32.h, not after.
18977 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18978 instead of gnutls_record_check_pending.
18980 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18982 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18984 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18985 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18988 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18990 * xterm.c (x_set_frame_alpha): Do not set property on anything

19013 * sysdep.c (wait_for_termination_1): Make static.
19014 (wait_for_termination, interruptible_wait_for_termination):
19015 Move after wait_for_termination_1.
19017 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
19019 * sysdep.c (interruptible_wait_for_termination): New function
19020 which is like wait_for_termination, but allows keyboard
19023 * callproc.c (Fcall_process): Add (:file "file") as an option for
19025 (Fcall_process_region): Ditto.
19027 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19029 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19030 rather than `XVECTOR (FOO)->size'.
19032 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19033 inttypes.h, as a gnulib replacement is used if it not available in
19036 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19038 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19039 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19040 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19042 * coding.c (coding_alloc_by_realloc): Error out if destination
19043 will grow beyond MOST_POSITIVE_FIXNUM.
19044 (decode_coding_emacs_mule): Abort if there isn't enough place in

19057 * window.c (window_scroll_line_based): Use a marker instead of
19058 simple variables to record original value of point. (Bug#7952)
19060 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19061 produced by %s or %c overflows available buffer space. (Bug#8545)
19063 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19065 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19066 (SIZE_MAX): Move defn after all includes, as they might #define it.
19068 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

19100 Improve `doprnt' and its usage. (Bug#8545)
19101 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19102 `format_end'. Remove support for %l as a conversion specifier.
19103 Don't use xrealloc. Improve diagnostics when the %l size modifier
19104 is used. Update the commentary.
19106 * eval.c (verror): Simplify calculation of size_t.
19108 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19111 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19113 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19116 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19118 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19119 This makes this file independent of the recent pseudovector change.
19121 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19123 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19125 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19126 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19127 Remove unused local.
19128 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19130 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19131 GCC 4.6.0 optimizes based on type-based alias analysis.
19132 For example, if b is of type struct buffer * and v of type struct
19133 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19134 != &v->size, and therefore "v->size = 1; b->size = 2; return
19135 v->size;" must therefore return 1. This assumption is incorrect
19136 for Emacs, since it type-puns struct Lisp_Vector * with many other
19137 types. To fix this problem, this patch adds a new type struct
19138 vectorlike_header that documents the constraints on layout of vectors
19139 and pseudovectors, and helps optimizing compilers not get fooled
19140 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19141 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19142 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19144 (XSETPVECTYPE): Rewrite in terms of new macro.
19145 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19146 This is a bit clearer, and further avoids the possibility of
19147 undesirable aliasing.
19148 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19149 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19150 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19151 since Lisp_Subr is a special case (no "next" field).
19152 (ASIZE): Now uses header.size rather than size.
19153 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19154 to avoid the hassle of writing XVECTOR (foo)->header.size.
19155 (struct vectorlike_header): New type.
19156 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19157 object, to help avoid aliasing.
19158 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19159 (SUBRP): Likewise, since Lisp_Subr is a special case.
19160 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19161 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19162 (struct Lisp_Hash_Table): Combine first two members into a single
19163 struct vectorlike_header member. All uses of "size" and "next" members
19164 changed to be "header.size" and "header.next".
19165 * buffer.h (struct buffer): Likewise.
19166 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19167 * frame.h (struct frame): Likewise.
19168 * process.h (struct Lisp_Process): Likewise.
19169 * termhooks.h (struct terminal): Likewise.
19170 * window.c (struct save_window_data, struct saved_window): Likewise.
19171 * window.h (struct window): Likewise.
19172 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19173 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19174 * buffer.c (init_buffer_once): Likewise.
19175 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19177 * process.c (Fformat_network_address): Use local var for size,
19180 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19182 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19183 * data.c (atof): Remove decl; no longer used or needed.
19184 (digit_to_number): Move to lread.c.
19185 (Fstring_to_number): Use new string_to_number function, to be
19186 consistent with how the Lisp reader treats infinities and NaNs.
19187 Do not assume that floating-point numbers represent EMACS_INT
19188 without losing information; this is not true on most 64-bit hosts.
19189 Avoid double-rounding errors, by insisting on integers when
19190 parsing non-base-10 numbers, as the documentation specifies.
19191 * lisp.h (string_to_number): New decl, replacing ...
19192 (isfloat_string): Remove.
19193 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19194 (read1): Do not accept +. and -. as integers; this
19195 appears to have been a coding error. Similarly, do not accept
19196 strings like +-1e0 as floating point numbers. Do not report
19197 overflow for integer overflows unless the base is not 10 which
19198 means we have no simple and reliable way to continue.
19199 Break out the floating-point parsing into a new
19200 function string_to_number, so that Fstring_to_number parses
19201 floating point numbers consistently with the Lisp reader.
19202 (digit_to_number): Move here from data.c. Make it static inline.
19203 (E_CHAR, EXP_INT): Remove, replacing with ...
19204 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19205 (string_to_number): New function, replacing isfloat_string.
19206 This function checks for valid syntax and produces the resulting
19207 Lisp float number too. Rework it so that string-to-number
19208 no longer mishandles examples like "1.0e+". Use strtoumax,
19209 so that overflow for non-base-10 numbers is reported only when
19210 there's no portable and simple way to convert to floating point.
19212 * textprop.c (set_text_properties_1): Rewrite for clarity,
19213 and to avoid GCC warning about integer overflow.
19215 * intervals.h (struct interval): Use EMACS_INT for members
19216 where EMACS_UINT might cause problems. See
19217 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19218 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19219 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19221 (offset_intervals): Tell GCC not to worry about length overflow
19222 when negating a negative length.
19224 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19225 (overrun_check_free): Likewise.
19227 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19228 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19231 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19232 (gnutls_make_error): Rename local to avoid shadowing.
19233 (gnutls_emacs_global_deinit): ifdef out; not used.
19234 (Fgnutls_boot): Use const for pointer to readonly storage.
19235 Comment out unused local. Fix pointer signedness problems.
19237 * lread.c (openp): Don't stuff size_t into an 'int'.
19238 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19239 about possible signed overflow.
19241 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19242 (GDK_KEY_g): Don't define if already defined.
19243 (xg_prepare_tooltip): Avoid pointer signedness problem.
19244 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19246 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19247 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19249 * xfns.c (Fx_window_property): Simplify a bit,
19250 to make a bit faster and to avoid GCC 4.6.0 warning.
19251 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19253 * fns.c (internal_equal): Don't assume size_t fits in int.
19255 * alloc.c (compact_small_strings): Tighten assertion a little.
19257 Replace pEd with more-general pI, and fix some printf arg casts.
19258 * lisp.h (pI): New macro, generalizing old pEd macro to other
19259 conversion specifiers. For example, use "...%"pI"d..." rather
19260 than "...%"pEd"...".
19261 (pEd): Remove. All uses replaced with similar uses of pI.
19262 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19263 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19264 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19265 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19266 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19267 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19268 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19270 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19271 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19272 * print.c (safe_debug_print, print_object): Likewise.
19273 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19275 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19276 avoiding the 0 flag, which is not portable.
19277 * process.c (Fmake_network_process): Use pI to avoid cast.
19278 * region-cache.c (pp_cache): Likewise.
19279 * xdisp.c (decode_mode_spec): Likewise.
19280 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19281 behavior on 64-bit hosts with printf arg.
19282 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19283 (x_stop_queuing_selection_requests): Likewise.
19284 (x_get_window_property): Don't truncate byte count to an 'int'
19287 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19288 here, since it parses constructs like leading '-' and spaces,
19289 which are not wanted; and it overflows with large numbers.
19290 Instead, simply match F[0-9]+, which is what is wanted anyway.
19292 * alloc.c: Remove unportable assumptions about struct layout.
19293 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19294 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19295 (allocate_vectorlike, make_pure_vector): Use the new macros,
19296 plus offsetof, to remove unportable assumptions about struct layout.
19297 These assumptions hold on all porting targets that I know of, but
19298 they are not guaranteed, they're easy to remove, and removing them
19299 makes further changes easier.
19301 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19302 This doesn't fix a bug but makes the code clearer.
19303 (string_overrun_cookie): Now const. Use initializers that
19304 don't formally overflow signed char, to avoid warnings.
19305 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19306 can cause Emacs to crash when string overrun checking is enabled.
19307 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19308 multiple of sizeof (EMACS_INT); it need not be, if
19309 alignof(EMACS_INT) < sizeof (EMACS_INT).
19310 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19312 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19319 supposed to be handshaking. (Bug#8556)
19320 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19322 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

19328 matches the current signal symbol.
19330 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
19332 * alloc.c (check_sblock, check_string_bytes)
19333 (check_string_free_list): Convert to standard C.
19335 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19337 * w32.c (emacs_gnutls_push): Fix typo.
19339 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19341 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19342 "cast to pointer from integer of different size".
19344 Improve doprnt and its use in verror. (Bug#8545)
19345 * doprnt.c (doprnt): Document the set of format control sequences
19346 supported by the function. Use SAFE_ALLOCA instead of always
19349 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19350 is one byte too soon. Don't use xrealloc; instead xfree and
19353 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19355 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19358 * gnutls.c: Renamed global_initialized to
19359 gnutls_global_initialized. Added internals for the
19360 :verify-hostname-error, :verify-error, and :verify-flags
19361 parameters of `gnutls-boot' and documented those parameters in the
19362 docstring. Start callback support.
19363 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19364 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19365 on error. Return error code.
19366 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19367 (emacs_gnutls_read): Likewise.
19368 (Fgnutls_boot): Return handshake error code.

19432 <char-direction-table>: Deleted.
19434 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19436 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19437 * doprnt.c: Include limits.h.
19438 (SIZE_MAX): New macro.
19439 (doprnt): Return a size_t value. 2nd arg is now size_t.
19440 Many local variables are now size_t instead of int or unsigned.
19441 Improve overflow protection. Support `l' modifier for integer
19442 conversions. Support %l conversion. Don't assume an EMACS_INT
19443 argument for integer conversions and for %c.
19445 * lisp.h (doprnt): Restore prototype.
19447 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19448 $(SRC)/character.h.
19450 * Makefile.in (base_obj): Add back doprnt.o.
19452 * deps.mk (doprnt.o): Add back prerequisites.
19453 (callint.o): Depend on character.h.
19455 * eval.c (internal_lisp_condition_case): Include the handler
19456 representation in the error message.
19457 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19458 when breaking from the loop.
19460 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19462 * callint.c (Fcall_interactively): When displaying error message
19463 about invalid control letter, pass the character's codepoint, not
19464 a pointer to its multibyte form. Improve display of the character
19465 in octal and display also its hex code.
19467 * character.c (char_string): Use %x to display the (unsigned)
19468 codepoint of an invalid character, to avoid displaying a bogus
19471 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19472 `error', not SYMBOL_NAME itself.
19474 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19475 character arguments to `error'.
19477 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19478 to `error' in error message about FINAL_CHAR argument. Make sure
19479 FINAL_CHAR is a character, and use %c when it is passed as
19480 argument to `error'.

19544 Define only if needed.
19546 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
19547 by pacifying GCC about it. Maybe it's time to retire it?
19548 * xfaces.c (USG, __TIMEVAL__): Likewise.
19550 * dispextern.h (struct redisplay_interface): Rename param
19551 to avoid shadowing.
19552 * termhooks.h (struct terminal): Likewise.
19553 * xterm.c (xembed_send_message): Likewise.
19555 * insdel.c (make_gap_smaller): Define only if
19556 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
19558 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
19561 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
19562 so that we aren't warned about unused symbols.

20015 * ccl.h (check_ccl_update, Vccl_program_table): Remove decls.
20016 * ccl.c (Vccl_program_table): Now static.
20017 (check_ccl_update): Remove; unused.
20019 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
20020 * category.h: ... from here.
20021 * category.c (check_category_table, set_category_set): Now static.
20023 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
20024 * lisp.h: Remove these decls.
20026 * buffer.c (buffer_count): Remove unused var.
20028 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
20029 so that it's not optimized away.
20030 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
20031 * dispextern.h (bidi_dump_cached_states): Remove, since it's
20032 exported only to the debugger.
20034 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
20035 * atimer.h (run_all_atimers): Remove; not exported.
20037 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20038 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20039 was inaccessible from Lisp.
20040 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20041 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20043 alloc.c: Import and export fewer symbols, and remove unused items.
20044 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20046 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20047 it's not optimized away by whole-program optimization.
20048 (message_enable_multibyte, free_misc): Remove.
20049 (catchlist, handlerlist, mark_backtrace):
20050 Declare only if BYTE_MARK_STACK.
20051 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
20052 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
20053 (message_enable_multibyte): Remove decl.
20054 (free_misc, interval_free_list, float_block, float_block_index):

20056 (cons_free_list, last_marked_index):
20058 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
20059 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
20060 (mark_backtrace): Define only if BYTE_MARK_STACK.
20061 * xdisp.c (message_enable_multibyte): Now static.
20063 Declare Lisp_Object Q* variables to be 'static' if not exported.
20064 This makes it easier for human readers (and static analyzers)
20065 to see whether these variables are used from other modules.
20066 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
20067 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
20068 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

20071 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
20072 * xmenu.c, xselect.c:
20073 Declare Q* vars static if they are not used in other modules.
20074 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
20075 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
20076 Remove decls of unexported vars.
20077 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20079 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20081 Make Emacs functions such as Fatom 'static' by default.
20082 This makes it easier for human readers (and static analyzers)
20083 to see whether these functions can be called from other modules.
20084 DEFUN now defines a static function. To make the function external
20085 so that it can be used in other C modules, use the new macro DEFUE.
20086 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20087 (Finit_image_library):
20088 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
20089 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
20090 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
20091 Remove decls, since these functions are now static.
20092 (Funintern, Fget_internal_run_time): New decls, since these functions
20093 were already external.
20095 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
20096 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

20102 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
20103 Mark functions with DEFUE instead of DEFUN,
20104 if they are used in other modules.
20105 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20106 decls for now-static functions.
20107 * buffer.h (Fdelete_overlay): Remove decl.
20108 * callproc.c (Fgetenv_internal): Mark as internal.

20116 * fileio.c (Fmake_symbolic_link): New forward static decl.
20117 * image.c (Finit_image_library): New forward static decl.
20118 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
20119 * intervals.h (Fprevious_property_change):
20120 (Fremove_list_of_text_properties): Remove decls.
20121 * keyboard.c (Fthis_command_keys): Remove decl.
20122 (Fcommand_execute): New forward static decl.
20123 * keymap.c (Flookup_key): New forward static decl.
20124 (Fcopy_keymap): Now static.
20125 * keymap.h (Flookup_key): Remove decl.
20126 * process.c (Fget_process): New forward static decl.
20127 (Fprocess_datagram_address): Mark as internal.

20143 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20145 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20146 when at ZV. (Bug#8487)
20148 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20150 * charset.c (Fclear_charset_maps): Use xfree instead of free.
20152 * keyboard.c (parse_tool_bar_item): Likewise.
20153 * sound.c (sound_cleanup, alsa_close): Likewise.
20154 * termcap.c (tgetent): Likewise.
20155 * xfns.c (x_default_font_parameter): Likewise.
20156 * xsettings.c (read_and_apply_settings): Likewise.
20158 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20159 (overrun_check_free): Protoize.
20161 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20163 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20164 since callers should never pass a negative size.
20165 Change the signature to match that of plain 'read' and 'write'; see
20166 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20167 * lisp.h: Update prototypes of emacs_write and emacs_read.
20169 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20171 * xdisp.c (redisplay_window): Don't try to determine the character
20172 position of the scroll margin if the window start point w->startp
20173 is outside the buffer's accessible region. (Bug#8468)
20175 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20177 Fix write-region and its subroutines for buffers > 2GB.
20178 * fileio.c (a_write, e_write): Modify declaration of arguments and
20179 local variables to support buffers larger than 2GB.
20180 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20182 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20183 argument, local variables, and return value.
20185 * lisp.h: Update prototypes of emacs_write and emacs_read.
20187 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20189 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20191 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20193 Fix more problems found by GCC 4.6.0's static checks.
20195 * xdisp.c (vmessage): Use a better test for character truncation.
20197 * charset.c (load_charset_map): <, not <=, for optimization,
20198 and to avoid potential problems with integer overflow.
20199 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20200 * casetab.c (set_identity, shuffle): Likewise.
20201 * editfns.c (Fformat): Likewise.
20202 * syntax.c (skip_chars): Likewise.
20204 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20205 This also lets GCC 4.6.0 generate slightly better loop code.
20207 * callint.c (Fcall_interactively): <, not <=, for optimization.
20208 (Fcall_interactively): Count the number of arguments produced,
20209 not the number of arguments given. This is simpler and lets GCC
20210 4.6.0 generate slightly better code.
20212 * ftfont.c: Distingish more carefully between FcChar8 and char.
20213 The previous code passed unsigned char * to a functions like
20214 strlen and xstrcasecmp that expect char *, which does not
20215 conform to the C standard.
20216 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20217 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20218 char * when the C standard requires it.
20220 * keyboard.c (read_char): Remove unused var.
20222 * eval.c: Port to Windows vsnprintf (Bug#8435).
20223 Include <limits.h>.
20224 (SIZE_MAX): Define if the headers do not.
20225 (verror): Do not give up if vsnprintf returns a negative count.
20226 Instead, grow the buffer. This ports to Windows vsnprintf, which
20227 does not conform to C99. Problem reported by Eli Zaretskii.
20228 Also, simplify the allocation scheme, by avoiding the need for
20229 calling realloc, and removing the ALLOCATED variable.
20231 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20233 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20234 But keep the doprint source code for now, as we might revamp it
20235 and use it again (Bug#8435).
20236 * lisp.h (doprnt): Remove.
20237 * Makefile.in (base_obj): Remove doprnt.o.
20238 * deps.mk (doprnt.o): Remove.
20240 error: Print 32- and 64-bit integers portably (Bug#8435).
20241 Without this change, on typical 64-bit hosts error ("...%d...", N)
20242 was used to print both 32- and 64-bit integers N, which relied on
20243 undefined behavior.
20244 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20245 * lisp.h (error, verror): Mark as printf-like functions.
20246 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20247 Report overflow in size calculations when allocating printf buffer.
20248 Do not truncate output string at its first null byte.
20249 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20250 Truncate the output at a character boundary, since vsnprintf does not
20252 * charset.c (check_iso_charset_parameter): Convert internal
20253 character to string before calling 'error', since %c now has the
20255 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20256 overflow when computing char to be passed to 'error'. Do not
20257 pass Lisp_Object to 'error'; pass the integer instead.
20258 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20259 formatted with plain %d.
20261 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20263 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20265 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20267 * xterm.c (x_catch_errors): Remove duplicate declaration.
20269 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20271 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20273 2011-04-10 Jim Meyering <meyering@redhat.com>
20275 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20276 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20277 return ssize_t not "int", and use size_t as the buffer length.
20278 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20279 * gnutls.h: Update declarations.
20280 * process.c (read_process_output): Use ssize_t, to match.
20281 (send_process): Likewise.
20283 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20285 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20287 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20289 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20290 Use unsigned char, to match FcChar8 type definition.
20292 * xterm.c (handle_one_xevent):
20293 * xmenu.c (create_and_show_popup_menu):
20294 * xselect.c (x_decline_selection_request)
20295 (x_reply_selection_request): Avoid type-punned deref of X events.
20297 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20299 Fix some uses of `int' instead of EMACS_INT.
20300 * search.c (string_match_1, fast_string_match)
20301 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20302 (scan_buffer, find_next_newline_no_quit)
20303 (find_before_next_newline, search_command, Freplace_match)
20304 (Fmatch_data): Make some `int' variables be EMACS_INT.
20306 * xdisp.c (display_count_lines): 3rd argument and return value now
20307 EMACS_INT. All callers changed.
20308 (pint2hrstr): Last argument is now EMACS_INT.
20310 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20311 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20312 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20313 (decode_coding_utf_16, decode_coding_emacs_mule)

20315 (decode_coding_ccl, decode_coding_charset)
20316 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
20317 (decode_coding_iso_2022, decode_coding_emacs_mule)
20318 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
20319 <char_offset, last_offset>: Declare EMACS_INT.

20321 (encode_coding_emacs_mule, encode_invocation_designation)
20322 (encode_designation_at_bol, encode_coding_iso_2022)
20323 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20324 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20326 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20327 (encode_invocation_designation): Last argument P_NCHARS is now
20329 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20330 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20332 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20335 * ccl.c (Fccl_execute_on_string): Declare some variables
20338 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20340 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20342 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20344 * process.c (Fformat_network_address): Doc fix.
20346 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20348 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20350 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20352 * keyboard.c (read_char): Call Lisp function help-form-show,
20353 instead of using internal_with_output_to_temp_buffer.
20354 (Qhelp_form_show): New var.
20355 (syms_of_keyboard): Use DEFSYM macro.
20357 * print.c (internal_with_output_to_temp_buffer): Function deleted.
20359 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
20361 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
20363 * process.c (Flist_processes): Remove to Lisp.
20364 (list_processes_1): Delete.
20366 2011-04-06 Eli Zaretskii <eliz@gnu.org>
20368 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20370 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20372 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20374 Fix more problems found by GCC 4.6.0's static checks.
20376 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
20378 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20380 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20382 * xdisp.c (vmessage): Mark as a printf-like function.
20384 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
20386 * sound.c (sound_warning): Don't crash if arg contains a printf format.
20388 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
20389 printf-like functions.
20390 (tiff_load): Add casts to remove these marks before passing them
20391 to system-supplied API.
20393 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20395 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20396 This avoids several warnings with gcc -Wstrict-overflow.
20397 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20398 directly, rather than having caller test rule sign. This avoids
20399 some unnecessary tests.
20400 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20401 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20402 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20404 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20405 (xfont_open): Avoid unnecessary tests.
20407 * composite.c (composition_gstring_put_cache): Use unsigned integer.

20416 by using the new macro.
20418 * textprop.c (set_text_properties_1): Change while to do-while,
20419 since the condition is always true at first.
20421 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20422 (interval_deletion_adjustment): Return unsigned value.
20425 * process.c (list_processes_1, create_pty, read_process_output):
20426 (exec_sentinel): Remove vars that were set but not used.
20427 (create_pty): Remove unnecessary "volatile"s.

20430 (read_process_output): Simplify nbytes computation if buffered.
20432 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
20434 * syntax.c (scan_words): Remove var that was set but not used.
20435 (update_syntax_table): Use unsigned instead of int.
20437 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

20441 * print.c (print_error_message): Avoid int overflow.
20443 * font.c (font_list_entities): Redo for clarity,
20444 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

20459 (wordify): Omit three unnecessary tests.
20461 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20462 All callers changed. This avoids the need for an unused var.
20464 * casefiddle.c (casify_region): Remove var that is set but not used.
20466 * dired.c (file_name_completion): Remove var that is set but not used.
20468 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20470 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20471 (Finsert_file_contents): Remove unnecessary code checking fd.
20473 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20474 Check for integer overflow on size calculations.
20476 * buffer.c (Fprevious_overlay_change): Remove var that is set
20479 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20480 Remove vars that are set but not used.
20481 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20482 (timer_check_2): Mark vars as initialized.
20484 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20486 * image.c (lookup_image): Remove var that is set but not used.
20487 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20489 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20490 that are set but not used.
20492 * xfns.c (make_invisible_cursor): Don't return garbage
20493 if XCreateBitmapFromData fails (Bug#8410).
20495 * xselect.c (x_get_local_selection, x_handle_property_notify):
20496 Remove vars that are set but not used.
20498 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20499 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20501 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20502 Remove var that is set but not used.
20503 (scroll_bar_windows_size): Now size_t, not int.
20504 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20505 Check for overflow.
20507 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20508 (map_tty_color) [!defined MSDOS]: Likewise.
20510 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20512 * coding.c: Remove vars that are set but not used.
20513 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20514 All callers changed.
20515 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20516 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20517 (decode_coding_charset): Remove vars that are set but not used.
20519 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20520 that is set but not used.
20522 * print.c (print_object): Remove var that is set but not used.
20524 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20525 The gnulib version avoids calling malloc in the usual case,
20526 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20527 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20528 * filelock.c (current_lock_owner): Likewise.
20529 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20530 * sysdep.c: Include allocator.h, careadlinkat.h.
20531 (emacs_no_realloc_allocator): New static constant.
20532 (emacs_readlink): New function.
20533 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20534 ../lib/careadlinkat.h.
20536 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20538 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20539 first non-nil return value).

20555 (get_per_char_metric): Remove parameter `f', unused since
20556 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20558 2011-04-02 Jim Meyering <meyering@redhat.com>
20560 do not dereference NULL upon failed strdup
20561 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20562 (ns_get_family): Likewise.
20564 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20566 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20568 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20570 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20573 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20575 Add lexical binding.
20577 * window.c (Ftemp_output_buffer_show): New fun.
20578 (Fsave_window_excursion):
20579 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20581 * lread.c (lisp_file_lexically_bound_p): New function.
20582 (Fload): Bind Qlexical_binding.
20583 (readevalloop): Remove `evalfun' arg.
20584 Bind Qinternal_interpreter_environment.
20585 (Feval_buffer): Bind Qlexical_binding.
20586 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20588 (syms_of_lread): Declare `lexical-binding'.
20590 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20592 * keyboard.c (eval_dyn): New fun.
20593 (menu_item_eval_property): Use it.
20595 * image.c (parse_image_spec): Use Ffunctionp.
20597 * fns.c (concat, mapcar1): Accept byte-code-functions.
20599 * eval.c (Fsetq): Handle lexical vars.
20600 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20601 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20602 (FletX, Flet): Obey lexical binding.
20603 (Fcommandp): Handle closures.
20604 (Feval): New `lexical' arg.
20605 (eval_sub): New function extracted from Feval. Use it almost
20606 everywhere where Feval was used. Look up vars in lexical env.
20608 (Ffunctionp): Move from subr.el.
20609 (Ffuncall): Handle closures.
20610 (apply_lambda): Remove `eval_flags'.
20611 (funcall_lambda): Handle closures and new byte-code-functions.
20612 (Fspecial_variable_p): New function.
20613 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20614 but without exporting it to Lisp.
20616 * doc.c (Fdocumentation, store_function_docstring):
20617 * data.c (Finteractive_form): Handle closures.
20619 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20622 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20624 (exec_byte_code): New function extracted from Fbyte_code to handle new
20625 calling convention for byte-code-functions. Add new byte-codes.
20627 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20629 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20631 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20633 * xdisp.c (redisplay_internal): Fix prototype.
20635 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20637 * xdisp.c (SCROLL_LIMIT): New macro.
20638 (try_scrolling): Use it when setting scroll_limit.
20639 Limit scrolling to 100 screen lines.
20640 (redisplay_window): Even when falling back on "recentering",
20641 position point in the window according to scroll-conservatively,
20642 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20644 (try_scrolling): When point is above the window, allow searching
20645 as far as scroll_max, or one screenful, to compute vertical
20646 distance from PT to the scroll margin position. This prevents
20647 try_scrolling from unnecessarily failing when
20648 scroll-conservatively is set to a value slightly larger than the
20649 window height. Clean up the case of PT below the margin at bottom
20650 of window: scroll_max can no longer be INT_MAX. When aggressive
20651 scrolling is in use, don't let point enter the opposite scroll
20652 margin as result of the scroll.
20653 (syms_of_xdisp) <scroll-conservatively>: Document the
20654 threshold of 100 lines for never-recentering scrolling.
20656 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20658 * dispextern.h (move_it_by_lines):
20659 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20660 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20661 (message_log_check_duplicate): Remove parameters `prev_bol' and
20662 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20663 (redisplay_internal): Remove parameter `preserve_echo_area',
20664 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20666 * indent.c (Fvertical_motion):
20667 * window.c (window_scroll_pixel_based, Frecenter):
20668 Don't pass `need_y_p' to `move_it_by_lines'.
20670 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20672 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20673 steal a few bits to be more compact.
20674 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20675 Remove unneeded casts.
20677 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20679 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20681 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20682 binding" message (bug#7967).
20684 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20686 Fix more problems found by GCC 4.6.0's static checks.
20688 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20689 Remove unused local var.
20691 * editfns.c (Fmessage_box): Remove unused local var.
20693 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20694 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20695 Omit unused local vars.
20696 * window.c (shrink_windows): Omit unused local var.
20697 * menu.c (digest_single_submenu): Omit unused local var.
20698 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20699 Omit unused local var.
20701 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20702 Don't assume string length fits in int.
20703 (keyremap_step, read_key_sequence): Use size_t for sizes.
20704 (read_key_sequence): Don't check last_real_key_start redundantly.
20706 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20707 instead of alloca (Bug#8344).
20709 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20710 (Fbacktrace_frame): Don't assume nframes fits in int.
20712 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20714 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20717 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20719 * cm.c (calccost): Turn while-do into do-while, for clarity.
20721 * keyboard.c (syms_of_keyboard): Use the same style as later
20722 in this function when indexing through an array. This also
20723 works around GCC bug 48267.
20725 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20727 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20729 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20730 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20732 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20733 This avoids undefined behavior on integer overflow, and is a bit
20734 more convenient anyway since it is compared to a size_t variable.
20736 Variadic C functions now count arguments with size_t, not int.
20737 This avoids an unnecessary limitation on 64-bit machines, which
20738 caused (substring ...) to crash on large vectors (Bug#8344).

20748 * fns.c (concat): Likewise.
20749 * frame.c (x_set_frame_parameters): Likewise.
20750 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20751 0 if not found, not -1. All callers changed.
20753 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20754 (stack_copy_size): Now size_t, not int.
20755 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20757 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20759 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20760 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20761 All callers changed.
20763 * lisp.h (multibyte_char_to_unibyte):
20764 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20765 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

20776 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20777 don't set the hook to nil, but remove the offending function instead.
20778 (Qcommand_hook_internal): Remove, unused.
20779 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20780 Vcommand_hook_internal.
20782 * eval.c (enum run_hooks_condition): Remove.
20783 (funcall_nil, funcall_not): New functions.
20784 (run_hook_with_args): Call each function through a `funcall' argument.
20785 Remove `cond' argument, now redundant.

20798 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20799 All callers changed.
20801 * w32.c (_wsa_errlist): Use braces for struct initializers.
20803 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
20804 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.

20950 * term.c (Fsuspend_tty, Fresume_tty):
20951 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
20952 * window.c (temp_output_buffer_show):
20953 * insdel.c (signal_before_change):

20959 * callint.c (Fcall_interactively):
20960 * buffer.c (Fkill_all_local_variables):
20961 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20963 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20964 unconditionally since it does the check itself.
20966 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20968 Fix more problems found by GCC 4.5.2's static checks.
20970 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20971 the first time through the loop, since we know p0 < p1 then.
20972 This also avoids a gcc -Wstrict-overflow warning.
20974 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20975 leading to a memory leak, possible in functions like
20976 load_charset_map_from_file that can allocate an unbounded number
20977 of objects (Bug#8318).
20979 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20980 that could (at least in theory) be that large.
20982 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20983 This is less likely to overflow, and avoids undefined behavior if
20984 overflow does occur. All callers changed. Use strtoul to scan
20985 for the unsigned long integer.
20986 (pint2hrstr): Simplify and tune code slightly.
20987 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

21002 * process.c (Fmake_network_process): Use socklen_t, not int,
21003 where POSIX says socklen_t is required in portable programs.
21004 This fixes a porting bug on hosts like 64-bit HP-UX, where
21005 socklen_t is wider than int (Bug#8277).
21006 (Fmake_network_process, server_accept_connection):
21007 (wait_reading_process_output, read_process_output):
21010 * process.c: Rename or move locals to avoid shadowing.

21020 Make tparam.h and terminfo.c consistent.
21021 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21022 Include tparam.h instead, since it declares them.
21023 * cm.h (PC): Remove extern decl; tparam.h now does this.
21024 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21025 * terminfo.c: Include tparam.h, to check interfaces.
21026 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21027 (tparam): Adjust signature to match interface in tparam.h;
21028 this removes some undefined behavior. Check that outstring and len
21029 are zero, which they always are with Emacs.
21030 * tparam.h (PC, BC, UP): New extern decls.
21032 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21033 (xftfont_open): Rename locals to avoid shadowing.

21050 (find_automatic_composition, composition_adjust_point): Likewise.
21051 (composition_update_it): Mark var as initialized.
21052 (find_automatic_composition): Mark vars as initialized,
21053 with a FIXME (Bug#8290).

21057 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21058 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21059 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21060 to avoid shadowing.

21072 Fix pointer signedness.
21073 (alsa_choose_format): Remove unused local var.
21074 (wav_play): Initialize a variable to 0, to prevent undefined
21075 behavior (Bug#8278).
21077 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21079 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21081 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21082 clobbering (Bug#8298).
21083 * sysdep.c (sys_subshell): Likewise.
21084 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21086 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21087 This should get cleaned up, so that child_setup has the
21088 same signature on all platforms.
21090 * callproc.c (call_process_cleanup): Now static.
21091 (relocate_fd): Rename locals to avoid shadowing.
21093 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21095 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21096 not to be necessary, and produces flickering.
21098 2011-03-20 Glenn Morris <rgm@gnu.org>
21100 * config.in: Remove file.
21102 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

21147 Define only if needed.
21149 * unexelf.c (unexec): Name an expression,
21150 to avoid gcc -Wbad-function-cast warning.
21151 Use a different way to cause a compilation error if anyone uses
21152 n rather than nn, a way that does not involve shadowing.
21153 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21155 * deps.mk (unexalpha.o): Remove; unused.
21157 New file unexec.h, the (simple) interface for unexec (Bug#8267).

21278 (RETALLOC_IF): Define only if needed.
21279 (WORDCHAR_P): Likewise. This one is never needed, but is used
21280 only in a comment talking about a compiler bug, so put inside
21281 the #if 0 of that comment.

21310 New macros, so that the caller can use some names other than
21311 gcpro1, gcpro2, etc.
21312 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21314 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21315 argument, for consistency with GCPRO2_VAR, etc: it is now the
21316 prefix of the variable, not the variable itself. All uses
21318 * dired.c (directory_files_internal, file_name_completion):
21319 Rename locals to avoid shadowing.
21321 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21322 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21323 dired.c's scmp function, had undefined behavior.

21325 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21326 * buffer.h: ... to here, because these macros use current_buffer,
21327 and the new implementation with inline functions needs to have
21328 current_buffer in scope now, rather than later when the macros
21330 (downcase, upcase1): New static inline functions.
21331 (DOWNCASE, UPCASE1): Reimplement using these functions.
21332 This avoids undefined behavior in expressions like
21333 DOWNCASE (x) == DOWNCASE (y), which previously suffered
21334 from race conditions in accessing the global variables

21384 to suppress a gcc -Wclobbered warning that does not seem to be right.
21385 (MAXPATHLEN): Define only if needed.
21387 * process.c (serial_open, serial_configure): Move decls from here ...
21388 * systty.h: ... to here, so that they can be checked.
21390 * fns.c (get_random, seed_random): Move extern decls from here ...

21747 -Wuninitialized does not deduce are never used uninitialized.
21748 (detect_coding_iso_2022): Initialize a local variable that might
21749 be used uninitialized. Leave a FIXME because it's not clear that
21750 this initialization is needed. (Bug#8211)
21751 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
21752 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):

21755 Remove unused macros.
21757 * category.c (hash_get_category_set): Remove unused local var.
21758 (copy_category_table): Now static, since it's not used elsewhere.

21783 Move these decls to tparam.h, and make them agree with what
21784 is actually in tparam.c. The previous trick of using incompatible
21785 decls in different modules does not conform to the C standard.
21786 All callers of tparam changed to use tparam's actual API.
21787 * tparam.c (tparam1, tparam, tgoto):
