3 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
4 (Fwrite_region): Update for new choose_write_coding_system args.
5 Move the last piece of choose_write_coding_system here. (Bug#13522)
6 (syms_of_fileio): Add choose-write-coding-system.
8 2013-01-30 Eli Zaretskii <eliz@gnu.org>
10 * w32.c (sys_open): Zero out the flags for the new file descriptor.
11 (sys_close): Zero out the flags for the file descriptor before
12 closing it. (Bug#13546)
14 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
15 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
16 CharNextExA and CharPrevExA to iterate over file names encoded in
19 * w32.c (w32_get_long_filename, init_environment, readlink):
20 Support file names encoded in DBCS codepages.
21 (readlink): Use the current file-name-coding-system, not the ANSI
22 codepage, to decode and handle targets of symlinks.
24 2013-01-28 Eli Zaretskii <eliz@gnu.org>
26 * w32.c (opendir): Now accepts a 'const char *'.
28 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
30 Remove obsolete redisplay code. See the discussion at
31 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
32 * dispnew.c (preemption_period, preemption_next_check): Remove.
33 (Vredisplay_preemption_period): Likewise.
34 (update_frame, update_single_window, update_window, update_frame_1):
35 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
36 used, following the 2012-06-22 change.
38 2013-01-25 Eli Zaretskii <eliz@gnu.org>
40 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)

50 2013-01-25 Eli Zaretskii <eliz@gnu.org>
52 * w32.c (max_filename_mbslen): New function.
53 (normalize_filename, readdir): Use it to detect locales where ANSI
54 encoding of file names uses a double-byte character set (DBCS).
55 If a DBCS encoding is used, advance by characters using
56 CharNextExA, instead of incrementing a 'char *' pointer. Use
57 _mbslwr instead of _strlwr. (Bug#13515)
59 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
60 request of memory reservation to 1.7GB. (Bug#13065)
62 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
64 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
65 at check_extra_latin label. (Bug#13505)
67 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
69 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
70 Avoid redundant calls to strlen.
72 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
74 Drop async_visible and async_iconified fields of struct frame.
75 This is possible because async input is gone; for details, see
76 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
77 * frame.h (struct frame): Remove async_visible and async_iconified
78 members, convert garbaged to unsigned bitfield. Adjust comments.
79 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
80 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
81 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
82 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
83 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
85 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
86 properly. Likewise for obscured.
88 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
91 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
93 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
95 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
96 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
98 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
100 * xdisp.c (message2, message2_nolog): Remove functions.
101 (message3, message3_nolog): Extract nbytes and multibyteness directly
102 from the string. Change all callers.
103 (message3_nolog): Don't set message_enable_multibyte since set_message
104 will reset it anyway.
105 (message1, message1_nolog): Use message3.
106 (vmessage): Use a stack allocated buffer rather than f->message_buf.
107 (with_echo_area_buffer): Remove last two arguments. Update all callers.
108 (set_message): Drop all but the second arg, which has to be a string.
109 (set_message_1): Simplify now that we know that a1 is NULL and the
110 second arg is a string.
111 * frame.h (struct frame): Remove `message_buf' field.
112 Use glyphs_initialized_p instead.
113 (FRAME_MESSAGE_BUF): Remove macro.
114 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
115 * lisp.h (message2, message2_nolog): Remove declarations.
116 (message3, message3_nolog): Update declarations.
117 * keyboard.c (read_char_minibuf_menu_text)
118 (read_char_minibuf_menu_width): Remove vars.
119 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
120 to correctly handle multibyte strings.
121 * frame.c (delete_frame): Don't free message_buf any more.
122 * editfns.c (message_text, message_length): Remove vars.
123 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
124 * fileio.c (auto_save_error): Use message3 instead of message2.
125 * dispnew.c (adjust_frame_message_buffer): Remove function.
127 2013-01-23 Eli Zaretskii <eliz@gnu.org>
129 * w32term.c (w32fullscreen_hook): Account correctly for the screen
130 real estate used for the tool bar and the menu bar.
132 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
134 * insdel.c (prepare_to_modify_buffer): Force redisplay if
135 hidden buffer is prepared to modification (Bug#13164).
137 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
139 * window.h (struct window): Change window_end_valid member from
140 Lisp_Object to a bitfield. Adjust comments.
141 (wset_window_end_valid): Remove.
142 * window.c (adjust_window_count): Clear window_end_valid.
143 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
144 (Fwindow_line_height, set_window_buffer, Frecenter)
145 (Fsplit_window_internal, Fdelete_other_windows_internal)
146 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
147 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
148 * xdisp.c (check_window_end, reconsider_clip_changes)
149 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
150 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
151 (find_first_unchanged_at_end_row, try_window_id): Likewise.
153 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
155 * xdisp.c (mark_window_display_accurate): Simplify the loop
156 assuming that the only one of vchild, hchild or buffer window
157 slots is non-nil. Call mark_window_display_accurate_1 for
158 the leaf windows only.
159 (mark_window_display_accurate_1): Always assume leaf window.
162 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
164 * emacs.c (Qkill_emacs_hook): Now static.
166 * fileio.c (Finsert_file_contents): Simplify.
167 Remove unnecessary assignments and tests.
169 2013-01-21 Eli Zaretskii <eliz@gnu.org>
171 * w32.c (acl_set_file): Don't test for errors unless
172 set_file_security returns FALSE. Avoids spurious errors when
175 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
177 * fileio.c (Finsert_file_contents): Revert code introduced at
178 2013-01-18 in favor of the simpler and generally better fix.
179 Save stack space by removing 'buffer' and reusing 'read_buf'
182 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
184 * lisp.h (eabs): Define unconditionally (Bug#13419).
185 The old "#if !defined (eabs)" was an unnecessary revenant of back
186 when this macro was called "abs". Document 'eabs' better.
188 2013-01-19 Glenn Morris <rgm@gnu.org>
190 * fns.c (Frandom): Doc fix.
192 2013-01-19 Eli Zaretskii <eliz@gnu.org>
194 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
195 segfault when there are lots of overlays.
197 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
198 when there are lots of overlays. See
199 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
200 for the details and a way to reproduce.
202 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
204 * fileio.c: Use O_APPEND to append.
205 This corresponds better to the natural interpretation of "append",
206 and avoids the need to open the output file twice, or to invoke
207 lseek when APPEND is neither nil nor a number.
208 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
209 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
210 file possibly twice, and lseeking to its end; this avoids the
211 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
212 at the same time: the combination is never needed and apparently
213 it doesn't work with DOS_NT.
215 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
216 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
218 Allow floating-point file offsets.
219 Problem reported by Vitalie Spinu in
220 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
221 * fileio.c (emacs_lseek): Remove.
222 (file_offset): New function.
223 (Finsert_file_contents, Fwrite_region): Use it.
225 2013-01-19 Chong Yidong <cyd@gnu.org>
227 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
228 aborting on Fsignal (Bug#13289).
230 2013-01-19 Eli Zaretskii <eliz@gnu.org>
232 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
233 set_file_security as failure due to insufficient privileges.
234 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
235 (fstat): Return owner and group like 'stat' and 'lstat' do.
237 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
239 Work around bug in CIFS and vboxsf file systems (Bug#13149).
240 The bug was observed on Ubuntu operating inside a virtual machine,
241 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
242 The workaround introduces a race condition on non-buggy hosts,
243 but it's an unlikely race and anyway there's a nearly identical
244 nearby race that can't be fixed.
245 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
247 (Fwrite_region): Test for file system time stamp bug.
248 (init_fileio): New function.
249 * lisp.h (init_fileio): Declare it.
250 * emacs.c (main): Call it.
252 * fileio.c (Finsert_file_contents): Simplify new diagnostic
253 and make it more consistent with other stat-failure diagnostics.
255 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
257 Fix crash when inserting data from non-regular files. See
258 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
259 for the error description produced by valgrind.
260 * fileio.c (read_non_regular): Rename to read_contents.
261 Free Lisp_Save_Value object used to pass parameters.
262 (read_non_regular_quit): Rename to read_contents_quit.
263 (Finsert_file_contents): Redesign internal file reading loop to adjust
264 gap and end positions after each read and so help make_gap to work
265 properly. Do not signal an I/O error too early and so do not leave
266 not yet decoded characters in a buffer, which was the reason of
267 redisplay crash. Use list2 to build return value. Adjust comments.
269 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
271 Close a race when statting and reading files (Bug#13149).
272 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
273 This avoids a race if the file is renamed between stat and open.
274 This race is not the problem originally noted in Bug#13149;
275 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
277 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
279 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
280 objects, related functions and macros.
281 (make_save_value): Adjust prototype.
282 (make_save_pointer): New prototype.

284 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
285 * alloc.c (format_save_value): Rename to make_save_value.
286 (make_save_pointer): New function.
287 (record_xmalloc): Use make_save_pointer.
288 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
289 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
290 Change users of make_save_value to make_save_pointer.
291 Likewise for format_save_value and make_save_value.
293 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
295 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
296 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.

300 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
302 * alloc.c (free_save_value): Now static.
304 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
306 * keymap.c (map_keymap_internal): Use format_save_value.
307 (map_keymap_char_table_item): Adjust accordingly.
308 * fileio.c (non_regular_fd, non_regular_inserted)
309 (non_regular_nbytes): Remove.
310 (Finsert_file_contents): Convert trytry to ptrdiff_t. Use
311 format_save_value to pass parameters to read_non_regular.
312 (read_non_regular): Use XSAVE_ macros to extract parameters.
314 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
316 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
318 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
320 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
321 extraction from any Lisp_Save_Value slot. Add type checking.
322 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
323 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
324 * xselect.c: All users changed.
326 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
328 Some convenient bits to deal with Lisp_Save_Values.
329 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.
330 (allocate_misc): Remove prototype.
331 (format_save_value): New prototype.

336 * editfns.c (save_excursion_save): Use format_save_value.
337 (save_excursion_restore): Use XSAVE_OBJECT.
339 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
341 Avoid needless casts with XSAVE_POINTER.
342 * alloc.c (mark_object) [GC_MARK_STACK]:
343 * dired.c (directory_files_internal_unwind):
344 * fileio.c (do_auto_save_unwind):
345 * gtkutil.c (pop_down_dialog):
346 * keymap.c (map_keymap_char_table_item):
347 * lread.c (load_unwind):
348 * nsmenu.m (pop_down_menu):
349 * print.c (print_object) [GC_MARK_STACK]:
350 * xfns.c (clean_up_file_dialog):
351 * xmenu.c (cleanup_widget_value_tree):
352 Omit casts between XSAVE_POINTER and a pointer type.
354 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
356 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
357 * eval.c (eval_sub): Protect `form' from being GCed before its
358 car and cdr becomes protected with the backtrace entry.
360 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
362 Make Lisp_Save_Value more versatile storage for up to four objects.
363 * lisp.h (toplevel): Enumeration to describe types of saved objects.
364 (struct Lisp_Save_Value): New layout. Adjust comments.
365 (XSAVE_POINTER): New macro.
366 (XSAVE_INTEGER): Likewise.
367 (allocate_misc): Add prototype.
368 (free_misc): Likewise.
369 * alloc.c (allocate_misc): Now global.
370 (free_misc): Likewise. Adjust comment.
371 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
372 (free_save_value): Likewise.
373 (mark_object): Likewise.
374 * editfns.c (save_excursion_save): Pack everything within
375 Lisp_Save_Value and so avoid xmalloc.
376 (save_excursion_restore): Adjust to match new layout. Use free_misc
377 because we do not allocate extra memory any more. Add eassert.
378 * print.c (print_object): New code to print Lisp_Save_Value. Do not
379 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
380 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
381 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:
382 Use XSAVE_POINTER and XSAVE_INTEGER where appropriate.
384 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>
386 * nsfont.m (LCD_SMOOTHING_MARGIN): New define.
387 (nsfont_draw): Remove disabling of LCD smoothing.

391 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
393 Fix SIGDANGER handlers, for AIX (Bug#13408).
394 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
395 Move handlers here from emacs.c; they were out of place.
397 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
399 * xterm.c (syms_of_xterm): Adjust documentation for
400 scroll-bar-adjust-thumb-portion.
402 2012-12-31 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
404 * xterm.c (scroll-bar-adjust-thumb-portion): New variable to
405 determine whether scroll bar thumb size should be adjusted or
406 not. Use variable for MOTIF.
408 * gtkutil.c (scroll-bar-adjust-thumb-portion): Use variable for
411 2013-01-13 Jan Djärv <jan.h.d@swipnet.se>

415 (doCommandBySelector:): Set processingCompose to NO.
417 * nsfont.m (ns_findfonts): Add block/unblock_input calls.
418 Remove check for fkeys count > zero, block/unblock fixes the real bug.
419 (nsfont_list_family): Add block/unblock_input calls.
420 (nsfont_open): Move block_input earlier. Add unblock_input before early
422 (nsfont_draw): Add block/unblock_input calls.
424 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
426 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
427 for old_charpos and old_bytepos.
429 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>
431 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
432 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
433 Clear tzvalbuf_in_environ if this workaround is in effect.
434 Problem and fix reported by Kazuhiro Ito.
436 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>
438 * insdel.c (Fcombine_after_change_execute, syms_of_insdel): Fix
439 ambiguous doc string cross-reference(s).
441 * keyboard.c (Fcommand_execute, syms_of_keyboard): Fix ambiguous
442 doc string cross-reference(s).
444 * window.c (Fwindow_point, syms_of_window): Fix ambiguous doc
445 string cross-reference(s).
447 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
449 Avoid unnecessary byte position calculation for the gap movement.
450 Since all users of move_gap do CHAR_TO_BYTE for other purposes
451 anyway, all of them should use move_gap_both instead.
452 * lisp.h (move_gap): Remove prototype.
453 * insdel.c (move_gap): Remove.
454 (move_gap_both): Add eassert.
455 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.
456 * xml.c (parse_region): Likewise.
458 2013-01-11 Paul Eggert <eggert@cs.ucla.edu>
460 emacsclient -t should not suspend Emacs server (Bug#13387)
461 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
463 * term.c (init_tty): Use them instead of rolling our own code.
464 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
465 switches from 'signal' to 'pthread_sigmask', which is safer in
466 multithreaded applications.
467 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
468 which has already arranged for that.
469 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
470 This is the main part of the bug fix.
472 2013-01-10 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)

540 2013-01-05 Eli Zaretskii <eliz@gnu.org>
542 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
543 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
544 digits for buffer positions, before misalignment starts.
545 Display "0" for integer "object" field.
546 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
547 Display the newline glyph more unambiguously.
549 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
551 * nsterm.m (ns_draw_underwave):
552 * w32term.c (w32_draw_underwave):
553 * xterm.c (x_draw_underwave): Make underwave look more triangular
554 and also degrade gracefully for small fonts. (Bug#13000)

583 2012-12-31 Eli Zaretskii <eliz@gnu.org>
585 * w32.c (unsetenv): Set up the string passed to _putenv
587 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
588 for the bug this caused.

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

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

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

679 * alloc.c (valid_lisp_object_p): Adjust comment.
681 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
683 * keyboard.c (record_asynch_buffer_change): Initialize an event
684 only if it's really needed.
685 * frame.h (enum output_method): Remove output_mac member since
686 it's a leftover from the deleted code.
687 * frame.c (Fframep): Adjust user here ...
688 * terminal.c (Fterminal_live_p): ... and here.
689 * coding.c (Qmac): Now here because it's only used to denote
690 end-of-line encoding type.
691 (syms_of_coding): DEFSYM it.
692 * frame.h (Qmac): Remove duplicated declaration.
694 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
696 * window.c (select_window_1): Now static, since it's used only here.

700 * window.c (window_body_cols): Subtract display margins from the
701 window body width on TTYs as well. See
702 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
703 for the original report.
705 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
707 * xdisp.c (redisplay_window): Remove inner local variable
708 because the outer shadowed one has the same meaning.
709 * xterm.h (struct x_output): Remove toolbar_detached member since it's
711 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
712 (xg_create_tool_bar): Adjust users.
714 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
716 * buffer.h (BUF_COMPACT): New macro to follow the common style.
717 * buffer.c (Fget_buffer_create): Use it to set compact field of
718 struct buffer_text to avoid accessing an uninitialized value
719 when compact_buffer is called for the first time.
720 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
721 (Fset_buffer_modified_p): Use buffer_window_count to check
722 whether the buffer is displayed in some window.
723 * xdisp.c (message_dolog): Likewise.
725 2012-12-23 Eli Zaretskii <eliz@gnu.org>
727 * w32.c (acl_set_file): If setting the file security descriptor
728 fails, and the new DACL is identical to the existing one, silently
729 return success. This fixes problems for users backing up their
730 own files without having the necessary privileges for setting
731 security descriptors.
733 * w32proc.c (reader_thread): Do not index fd_info[] with negative
735 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
736 after WaitForSingleObject returns normally. This expedites reader
737 thread shutdown when delete_child triggers it.
738 (reap_subprocess): More accurate commentary for why we call
739 delete_child only when cp->fd is negative.
741 * w32.c (sys_close): Do not call delete_child on a subprocess
742 whose handle is not yet closed. Instead, set its file descriptor
743 to a negative value, so that reap_subprocess will call
744 delete_child on that subprocess when its SIGCHLD arrives.
745 This avoids closing handles used for communications between sys_select
746 and reader_thread, which doesn't give sys_select a chance to
747 notice that the process exited and invoke the SIGCHLD handler for
750 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
752 * nsfns.m (Fns_do_applescript): Run event loop until script has

763 * w32term.c (w32fullscreen_hook): New function.
764 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
766 2012-12-21 Eli Zaretskii <eliz@gnu.org>
768 * fileio.c (Finsert_file_contents): Doc fix.
770 * w32proc.c (new_child, delete_child, find_child_pid): For a
771 subprocess, consider its slot being in use as long as its process
772 handle (procinfo.hProcess) is not NULL. This avoids reusing the
773 slot when a new process is started immediately after killing
774 another one, without waiting enough time for the first process to
775 be reaped and resources allocated for it be orderly freed.
777 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
779 2012-12-21 Chong Yidong <cyd@gnu.org>

785 2012-12-21 Eli Zaretskii <eliz@gnu.org>
787 * w32.c (get_name_and_id): Always pass NULL as the first argument
788 of lookup_account_sid. Avoids crashes with UNC file names that
789 refer to DFS domains, not to specific machine names. (Bug#12621)
790 Remove now unused argument FNAME; all callers changed.
791 (get_file_owner_and_group): Remove now unused argument FNAME; all
794 2012-12-21 Chong Yidong <cyd@gnu.org>
796 * editfns.c (Finsert_char): Since read-char-by-name now signals an
797 error for invalid chars, don't check for a nil return value.
799 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
801 Avoid calls to CHAR_TO_BYTE if byte position is known.
802 * editfns.c (make_buffer_string_both): Use move_gap_both.
803 (Fbuffer_string): Use make_buffer_string_both.
804 * marker.c (buf_charpos_to_bytepos): Convert to eassert.

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

823 (redisplay_internal): Don't bother selecting the frame to get the
824 proper value of frame-local variables (bug#13225).
826 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
828 * textprop.c (set_text_properties_1): Do not allow NULL interval.
829 Rename 4th argument since it may be buffer or string. Adjust comment.
830 * intervals.c (graft_intervals_info_buffer): Find an interval here.
832 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
834 * coding.c (Fdetect_coding_region): Do not check start and end with
835 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
836 (code_convert_region): Likewise.
838 2012-12-18 Eli Zaretskii <eliz@gnu.org>
840 * w32.c (acl_get_file, acl_set_file): Run the file name through

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

887 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
888 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
889 for some of that bug's symptoms can now cause Emacs to abort.
890 Remove the workaround.

970 security APIs. This is to make most callers of 'stat' and
971 'lstat', which don't need that information, much faster.
973 * dired.c (Ffile_attributes) [WINDOWSNT]:
974 Set w32_stat_get_owner_group to a non-zero value, to request accurate
975 owner and group information from 'lstat'.
977 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
979 * fileio.c (Finsert_file_contents): Don't put tail into head area,
980 as that confuses set-auto-coding, so insist on the head-read
981 returning the full 1024 bytes. Let lseek compute the tail offset;
982 less work for us. Do not ignore I/O errors when reading the tail.
984 * xdisp.c: Minor style fixes.
985 (init_iterator): Hoist assignment out of if-expression.
986 (markpos_of_region): Callers now test for sign, not for -1.

1012 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1013 Remove unnecessary S_ISLNK test, as (contra the comments) this
1014 function can't copy symlinks. Improve quality of error message
1015 when attempting to copy files that are neither regular files nor

1046 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1047 left_box_line_p and right_box_line_p flags of the glyph for R2L
1048 glyph rows. (Bug#13011)

1062 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1063 encoded_file_name, which is what it is.
1065 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

1091 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
1094 * w32fns.c (cache_system_info): Initialize the global hinst
1095 variable here so various initialization calls DTRT.
1097 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1098 (hinst): Remove unneeded extern declaration.
1099 (_start): Remove initialization of above variables; remove
1100 initialization of hinst, as cache_system_info now does that.

1248 * dbusbind.c (Fdbus_init_bus):
1250 * xterm.c (x_term_init):

1261 no longer needed here.

1263 Move to inside set_time_zone_rule; they don't need file scope any more.
1264 (set_time_zone_rule): Maintain the TZ=value string separately.
1265 (syms_of_editfns): Don't initialize initial_tz;
1266 init_editfns now does it.

1314 This will cause a production Emacs to dump core instead of
1317 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1319 * frame.c (make_frame): Do not set window's buffer to t.
1320 * window.c (Fsplit_window_internal): Likewise. Previously it was
1321 used to indicate that the window is being set up. Now we use
1322 set_window_buffer for all new windows, so the condition in ...
1323 (Fset_window_buffer): ... is always true and can be removed.
1325 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
1327 Convenient macro to check whether the buffer is hidden.
1328 * buffer.h (BUFFER_HIDDEN_P): New macro.

1354 Fix a recently-introduced delete-process race condition.
1355 * callproc.c, process.h (record_kill_process):
1356 New function, containing part of the old call_process_kill.
1357 (call_process_kill): Use it.
1358 This does not change call_process_kill's behavior.
1359 * process.c (Fdelete_process): Use record_kill_process to fix a
1360 race condition that could cause Emacs to lose track of a child.
1362 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
1364 Avoid code duplication between prev_frame and next_frame.
1365 * frame.c (candidate_frame): New function. Add comment.
1366 (prev_frame, next_frame): Use it. Adjust comment.
1368 2012-12-06 Eli Zaretskii <eliz@gnu.org>
1370 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
1371 fails, signal an error instead of continuing with an empty
1373 Encode expanded temp file pattern before passing it to mkstemp or
1376 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
1377 Encode the file name before passing it to dostounix_filename, in
1378 case it will downcase it (under w32-downcase-file-names).
1381 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
1383 Minor call-process cleanups.
1384 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
1385 at the same time as other platforms, to simplify analysis.
1386 No need for fd0_volatile since we have synch_process_fd.
1387 Avoid needless emacs_close; arg is always negative.
1389 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
1391 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous

1396 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
1397 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer

1404 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1405 members to a bitfields.
1407 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1409 Don't let call-process be a zombie factory (Bug#12980).
1410 Fixing this bug required some cleanup of the signal-handling code.
1411 As a side effect, this change also fixes a longstanding rare race
1412 condition whereby Emacs could mistakenly kill unrelated processes,
1413 and it fixes a bug where a second C-g does not kill a recalcitrant
1414 synchronous process in GNU/Linux and similar platforms.
1415 The patch should also fix the last vestiges of Bug#9488,
1416 a bug which has mostly been fixed on the trunk by other changes.
1417 * callproc.c, process.h (synch_process_alive, synch_process_death)
1418 (synch_process_termsig, sync_process_retcode):
1419 Remove. All uses removed, to simplify analysis and so that
1420 less consing is done inside critical sections.
1421 * callproc.c (call_process_exited): Remove. All uses replaced
1422 with !synch_process_pid.
1423 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1424 These take the role of what used to be in unwind-protect arg.
1426 (block_child_signal, unblock_child_signal):
1427 New functions, to avoid races that could kill innocent-victim processes.
1428 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1429 (call_process_kill): Record killed processes as deleted, so that
1430 zombies do not clutter up the system. Do this inside a critical
1431 section, to avoid a race that would allow the clutter.
1432 (call_process_cleanup): Fix code so that the second C-g works again
1433 on common platforms such as GNU/Linux.
1434 (Fcall_process): Create the child process in a critical section,
1435 to fix a race condition. If creating an asynchronous process,
1436 record it as deleted so that zombies do not clutter up the system.
1437 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1438 light of these changes. Omit unnecessary call to emacs_close
1439 before failure, as the unwind-protect code does that.
1440 * callproc.c (call_process_cleanup):
1441 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1442 * process.c (record_deleted_pid): New function, containing
1443 code refactored out of Fdelete_process.
1444 (Fdelete_process): Use it.
1445 (process_status_retrieved): Remove. All callers changed to use
1446 child_status_change.
1447 (record_child_status_change): Remove, folding its contents into ...
1448 (handle_child_signal): ... this signal handler. Now, this
1449 function is purely a handler for SIGCHLD, and is not called after
1450 a synchronous waitpid returns; the synchronous code is moved to
1451 wait_for_termination. There is no need to worry about reaping
1452 more than one child now.
1453 * sysdep.c (get_child_status, child_status_changed): New functions.
1454 (wait_for_termination): Now takes int * status and bool
1455 interruptible arguments, too. Do not record child status change;
1456 that's now the caller's responsibility. All callers changed.
1457 Reimplement in terms of get_child_status.
1458 (wait_for_termination_1, interruptible_wait_for_termination):
1459 Remove. All callers changed to use wait_for_termination.
1460 * syswait.h: Include <stdbool.h>, for bool.
1461 (record_child_status_change, interruptible_wait_for_termination):
1463 (record_deleted_pid, child_status_changed): New decls.
1464 (wait_for_termination): Adjust to API changes noted above.
1466 * bytecode.c, lisp.h (Qbytecode): Remove.
1467 No longer needed after 2012-11-20 interactive-p changes.
1469 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1471 * xdisp.c (redisplay_window): If the cursor is visible, but inside

1482 (modify_region_1): ...new prototype.
1483 * textprop.c (modify_region): Now static. Adjust users.
1484 * insdel.c (modify_region): Rename to...
1485 (modify_region_1): ...new function to work with current buffer.
1486 Adjust comment and users. Use true and false for booleans.
1488 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1490 * alloc.c (free_save_value): New function.
1491 (safe_alloca_unwind): Use it.

1495 (save_excursion_restore): Adjust to match saved data structure.
1496 Use free_save_value to offload some work from GC. Drop obsolete
1499 2012-12-03 Chong Yidong <cyd@gnu.org>
1501 * fileio.c (Vauto_save_list_file_name): Doc fix.
1503 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1505 * w32fns.c: Remove prototype of atof.
1506 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1508 (file_dialog_callback): Make it UINT_PTR.
1510 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1513 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1514 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already

1519 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1521 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1523 Fix xpalloc confusion after memory is exhausted.
1524 * alloc.c (xpalloc): Comment fix.
1525 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1526 and signals an error, do not clear charset_table_size, as
1527 charset_table is still valid.
1528 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1530 Use execve to avoid need to munge environ (Bug#13054).
1531 * callproc.c (Fcall_process):
1532 * process.c (create_process):
1533 Don't save and restore environ; no longer needed.
1534 * callproc.c (child_setup):
1535 Use execve, not execvp, to preserve environ.
1537 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1539 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1541 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1543 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1544 display for sliced images (Bug#10500).
1546 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1548 2012-11-30 Juanma Barranquero <lekktu@gmail.com>

1551 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1553 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1555 * xdisp.c (window_outdated): Remove eassert since it hits
1556 some suspicious corner cases (see Bug#13007 and Bug#13012).
1557 (mode_line_update_needed): New function.
1558 (redisplay_internal, redisplay_window): Use it.
1559 (ensure_selected_frame): New function.

1562 (buffer_shared_and_changed): ...near to its real use.
1564 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1566 * callproc.c (Fcall_process): Don't misreport vfork failure.
1568 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1570 * callproc.c (Fcall_process): Fix vfork portability problems.
1571 Do not assume that fd[0], count, filefd, and save_environ survive
1572 vfork. Fix bug whereby wrong errno value could be reported for
1573 pipe failure. Some minor cleanups, too, as follows. Move buf and
1574 bufsize to the context where they're needed. Change new_argv to
1575 be of type char **, as this is more convenient and avoids casts.
1576 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1577 Now local constants, not macros.
1579 2012-11-18 Kenichi Handa <handa@gnu.org>
1581 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"

1614 violations when repeatedly clicking on the "Top" link of the
1615 "bread-crumbs" in Info buffers.

1629 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1630 between bpos_covered and bpos_max. This fixes cursor display when
1631 several display strings follow each other.
1633 * .gdbinit (pgx): If the glyph's object is a string, display the
1634 pointer to string data, rather than the value of the string object
1635 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1637 * indent.c (Fvertical_motion): If the starting position is covered
1638 by a display string, return to one position before that, to avoid
1639 overshooting it inside move_it_to. (Bug#12930)
1641 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1643 * frame.h (struct frame): Remove display_preempted member

1652 Drop unused pending_menu_activation member.
1653 * xterm.h (struct x_output): Drop outdated #if 0 code.
1654 Use bitfields for explicit_parent, asked_for_visible,
1655 has_been_visible and net_wm_state_hidden_seen members.
1657 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1659 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1660 of a literal "/". (Bug#12955)
1661 (gl-stamp): Invoke fc.exe directly, not through cmd.

1666 * dired.c: Assume HAVE_DIRENT_H.
1667 (NAMLEN): Remove, replacing with ...
1668 (dirent_namelen): New function. All uses changed. Use the GNU macro
1669 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1670 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1671 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1672 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1674 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1675 * ndir.h: Rename to ../nt/inc/dirent.h.
1676 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1677 Do not include <dirent.h>; no longer needed.
1678 * w32.c: Include <dirent.h> rather than "ndir.h".
1680 2012-11-23 Chong Yidong <cyd@gnu.org>
1682 * xftfont.c (xftfont_open): Remove duplicate assignment.
1684 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1686 * alloc.c (Fgarbage_collect): Unblock input after clearing
1687 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1688 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1689 * msdos.c (IT_frame_up_to_date): Use it here...
1690 * w32term.c (w32_frame_up_to_date): ...here...
1691 * xterm.c (XTframe_up_to_date): ...and here...
1692 * nsterm.m (ns_frame_up_to_date): ...but not here.
1693 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1695 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1696 Do not check whether GC is in progress.

1701 (update_menu_bar, update_tool_bar): Use it to
1702 simplify large 'if' statements.

1704 'tail' and 'frame' local variables.
1706 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1708 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1709 with Windows system header.
1711 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1713 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1714 * alloc.c: Assume unistd.h exists.

1730 * emacs.c (main): Set the G_SLICE environment variable for all
1731 Cygwin builds, not just GTK builds. See
1732 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1734 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1736 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1737 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1738 Define for the MSVC compiler.
1740 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1742 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1743 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1744 dostounix_filename. Prevents crashes down the road, because
1745 dostounix_filename assumes it gets a unibyte string.
1746 Reported by Michel de Ruiter <michel@sentient.nl>, see

1782 2012-11-19 Daniel Colascione <dancol@dancol.org>
1784 * w32fns.c (Fx_file_dialog):
1785 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1786 cygwin_convert_file_name*.
1788 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1789 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1791 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1793 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1795 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1797 * w32select.c: Include w32common.h before w32term.h, so that
1798 windows.h gets included before w32term.h uses some of its
1799 features, see below.
1801 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1803 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

1814 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1815 Needed following 2012-10-20 change. (Bug#12902)
1817 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1819 * w32proc.c (waitpid): Remove unused label get_result.
1821 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1823 * makefile.w32-in (SYSWAIT_H): New macro.
1824 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1825 ($(BLD)/sysdep.$(O)): Update dependencies.

1831 * emacs.c, term.c (O_RDWR): Remove.
1832 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1833 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1834 * nsterm.m: Assume <fcntl.h> exists.
1835 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1836 (create_pty, Fmake_network_process, server_accept_connection)
1837 (wait_reading_process_output, init_process_emacs):
1839 (wait_reading_process_output): Put in a special case for WINDOWSNT
1840 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1841 It's not clear this is needed, but it's a more-conservative change.
1842 (create_process): Assume FD_CLOEXEC.
1843 (create_process, create_pty): Assume O_NOCTTY.
1844 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1845 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1846 Omit if not DOS_NT, since F_GETFL is not defined there.
1847 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1848 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1850 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1851 lack it, since gnulib guarantees this.
1852 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1854 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1856 * w32.c (faccessat): Pretend that directories have the execute bit
1857 set. Emacs expects that, e.g., in files.el:cd-absolute.
1859 * w32proc.c (create_child): Don't clip the PID of the child
1860 process to fit into an Emacs integer, as this is no longer a
1862 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1863 reaping only the process specified by PID argument, if that is
1864 positive. Use PID instead of dead_child to know which process to
1865 reap. Wait for the child to die only if WNOHANG is not in
1867 (sys_select): Don't set dead_child.
1869 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1870 as it is no longer needed.
1872 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1874 (record_child_status_change): Remove the setting of
1875 record_at_most_one_child for the !WNOHANG case.
1877 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1879 Fix problems in ns port found by static checking.
1880 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1881 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1882 not to process group.
1883 (ns_select): Use emacs_write, not write, as that's more robust
1884 in the presence of signals.
1885 (fd_handler:): Check for read errors.
1887 2012-11-16 Glenn Morris <rgm@gnu.org>
1889 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)

1897 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1898 use the same value of thread handle.
1899 (start_timer_thread): If the timer thread exited (due to error),
1900 clean up by closing the two handles it used. Duplicate the caller
1901 thread's handle here, so it gets duplicated only once, when
1902 launching the timer thread. Set priority of the timer thread, not
1904 (getitimer): Don't duplicate the caller thread's handle here.
1907 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1909 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1912 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1914 Remove no-longer-used pty_max_bytes variable.
1915 * process.c (pty_max_bytes): Remove; unused.
1916 (send_process): Do not set it.
1918 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1920 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1921 Update dependencies.
1923 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1925 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1926 This follows up on the 2012-09-29 patch that removed indirection
1927 for the 'function' field. Reported by Sergey Vinokurov in
1928 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1930 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1932 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1933 different name, as the MS runtime does not have such a function,
1934 and probably never will.) All callers changed. Ignore DIRFD
1935 value if PATH is an absolute file name, to match Posix spec
1936 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1939 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1941 * xdisp.c (echo_area_display, redisplay_internal):
1942 Omit redundant check whether frame_garbaged is set.
1944 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1946 Use faccessat, not access, when checking file permissions (Bug#12632).
1947 This fixes a bug that has been present in Emacs since its creation.
1948 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1949 which must set some sort of record. (Torek's bug report was against
1950 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1951 same common flaw.) See Torek's Usenet posting
1952 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1953 Posted: Fri Apr 8 14:18:56 1983.
1954 * Makefile.in (LIB_EACCESS): New macro.
1956 * callproc.c (init_callproc):
1957 * charset.c (init_charset):
1958 * fileio.c (check_existing, check_executable, check_writable)
1960 * lread.c (openp, load_path_check):
1961 * process.c (allocate_pty):
1963 Use effective UID when checking permissions, not real UID.
1964 * callproc.c (init_callproc):
1965 * charset.c (init_charset):
1966 * lread.c (load_path_check, init_lread):
1967 Test whether directories are accessible, not merely whether they exist.
1968 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1969 * fileio.c (check_existing, check_executable, check_writable)
1971 Use symbolic names instead of integers for the flags, as they're
1973 (check_writable): New arg AMODE. All uses changed.
1974 Set errno on failure.
1975 (Ffile_readable_p): Use faccessat, not stat + open + close.
1976 (Ffile_writable_p): No need to call check_existing + check_writable.
1977 Just call check_writable and then look at errno. This saves a syscall.
1978 dir should never be nil; replace an unnecessary runtime check
1979 with an eassert. When checking the parent directory of a nonexistent
1980 file, check that the directory is searchable as well as writable, as
1981 we can't create files in unsearchable directories.
1982 (file_directory_p): New function, which uses 'stat' on most platforms
1983 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1984 (Ffile_directory_p, Fset_file_times): Use it.
1985 (file_accessible_directory_p): New function, which uses a single
1986 syscall for efficiency.
1987 (Ffile_accessible_directory_p): Use it.
1988 * xrdb.c (file_p): Use file_directory_p.
1989 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1990 * lread.c (openp): When opening a file, use fstat rather than
1991 stat, as that avoids a permissions race. When not opening a file,
1992 use file_directory_p rather than stat.
1993 (dir_warning): First arg is now a usage string, not a format.
1994 Use errno. All uses changed.
1995 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1996 that merely introduced a race.
1997 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1998 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1999 and similarly for the other O_* flags.
2000 * w32.c (sys_faccessat): Rename from sys_access and switch to
2001 faccessat's API. All uses changed.
2002 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2003 (magic_db): Rename from magic_file_p.
2004 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2005 char *, so that we don't have to test for file existence
2006 separately from opening the file for reading. This removes a race
2007 fixes a permission-checking problem, and simplifies the code.
2009 (file_p): Remove; no longer needed.
2011 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2013 Omit glyphs initialization at startup.
2014 * dispnew.c (glyphs_initialized_initially_p): Remove.
2015 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2016 (Fredraw_frame): Move actual code from here...
2017 (redraw_frame): ...to here. Add eassert. Adjust comment.
2018 (Fredraw_display): Use redraw_frame.
2019 * xdisp.c (clear_garbaged_frames): Likewise.
2021 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2023 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2024 passed to pint2str and pint2hrstr to be at most the size of the
2025 frame's decode_mode_spec_buffer. This avoids crashes with very
2026 large values of FIELD_WIDTH argument to decode_mode_spec.
2029 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2031 Fix a race with verify-visited-file-modtime (Bug#12863).
2032 Since at least 1991 Emacs has ignored an mtime difference of no
2033 more than one second, but my guess is that this was to work around
2034 file system bugs that were fixed long ago. Since the race is
2035 causing problems now, let's remove that code.
2036 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2037 whose time stamp is off by no more than a second. Insist that the
2038 file time stamps match exactly.
2040 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2042 * frame.h (struct frame): Convert external_tool_bar member to
2043 1-bit unsigned bitfield.
2044 * termhooks.h (struct terminal): Remove mouse_moved member since
2045 all users are long dead. Adjust comment on mouse_position_hook.
2047 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2049 Simplify by using FOR_EACH_FRAME here and there.
2050 * frame.c (next_frame, prev_frame, other_visible_frames)
2051 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2052 * w32term.c (x_window_to_scroll_bar): Likewise.
2053 * window.c (window_list): Likewise.
2054 * xdisp.c (x_consider_frame_title): Likewise.
2055 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2056 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2057 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2058 * xmenu.c (menubar_id_to_frame): Likewise.
2059 * xselect.c (frame_for_x_selection): Likewise.
2060 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2061 (x_window_to_menu_bar): Likewise.
2062 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2064 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2066 * data.c (Qdefalias_fset_function): Now static.
2068 Another tweak to vectorlike_header change.
2069 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
2070 Remove, and replace all uses with ...
2071 (next_in_free_list, set_next_in_free_list):
2072 New functions, which respect C's aliasing rules better.
2074 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2076 * window.c (list4i): Rename from 'quad'. All uses changed.
2077 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2079 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2081 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
2082 warning about mixing declarations and code in ISO C90.
2084 2012-11-10 Martin Rudalics <rudalics@gmx.at>
2086 * window.c (Fsplit_window_internal): Set combination limit of
2087 new parent window to t iff Vwindow_combination_limit is t;
2088 fixing a regression introduced with the change from 2012-09-22.
2089 (Fset_window_combination_limit): Fix doc-string.
2091 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2093 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2094 amount when the scroll margins are too large. When scrolling
2095 backwards in the buffer, give up if cannot reach point or the
2096 scroll margin within a reasonable number of screen lines.
2097 Fixes point position in window under scroll-up/down-aggressively when
2098 point is positioned many lines beyond the window top/bottom.
2101 * ralloc.c (relinquish): If real_morecore fails to return memory
2102 to the system, don't crash; instead, leave the last heap
2103 unchanged and return. (Bug#12774)
2105 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2107 * lisp.h (AUTOLOADP): New macro.
2108 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
2109 * data.c (Ffset): Remove special ad-advice-info handling.
2110 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
2112 (Finteractive_form): Simplify.
2113 (Fquo): Don't insist on having at least 2 arguments.
2114 (Qdefalias_fset_function): New var.
2116 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2118 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
2120 * nsfont.m (Qcondensed, Qexpanded): New variables.
2121 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
2122 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
2124 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2126 Fix recently introduced crash on MS-Windows (Bug#12839).
2127 * w32term.h (struct scroll_bar): Use convenient header.
2128 (SCROLL_BAR_VEC_SIZE): Remove.
2129 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2131 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2133 Tweak last vectorlike_header change.
2134 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2135 vectorlike object on the free list. This is introduced to avoid
2136 some (but not all) pointer casting and aliasing problems, see
2137 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2138 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
2140 (xvectype, xvecsize): Use them to examine Lisp_Object values.
2142 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2144 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2145 been removed, so remove them here also.
2147 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2149 * doc.c (Fdocumentation): Handle new property
2150 dynamic-docstring-function to replace the old ad-advice-info.
2152 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2154 * fns.c (Qeql, hashtest_eq): Now static.
2156 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2158 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2159 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2160 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
2161 * buffer.c (compare_overlays): Use XLI rather than XHASH.
2163 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
2165 Use same hash function for hashfn_profiler as for hash_string etc.
2166 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2167 * lisp.h (sxhash_combine): New inline function, with the contents
2168 of the old SXHASH_COMBINE.
2169 * profiler.c (hashfn_profiler): Use it, instead of having a
2170 special hash function containing a comparison that always yields 1.
2172 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2174 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2175 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2176 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2179 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2181 * image.c (xpm_make_color_table_h): Fix compiler error because
2182 make_hash_table changed.
2184 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2186 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2188 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2190 Use ad-hoc comparison function for the profiler's hash-tables.
2191 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2192 (make_log): Use them.
2193 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2194 call Fequal any more.

2203 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2204 (hash_lookup, hash_remove_from_table): Move assertion checking of
2205 hashfn result here. Check hash-equality before calling cmpfn.

2215 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2217 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2218 value of w32-scroll-lock-modifier is neither nil nor one of the
2219 known key modifiers. (Bug#12806)
2221 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2223 Shrink struct vectorlike_header to the only size field.
2224 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2226 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2227 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2228 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2229 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2230 information from the vector header. Adjust comment.
2231 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
2232 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
2234 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.

2240 (enum mem_type): Adjust comment.
2241 (NEXT_IN_FREE_LIST): New macro.
2242 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
2243 (Fmake_bool_vector): Likewise.
2244 (struct large_vector): New type to represent allocation unit for
2245 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2246 (large_vectors): Change type to struct large_vector.
2247 (allocate_vector_from_block): Simplify.
2248 (PSEUDOVECTOR_NBYTES): Replace with...
2249 (vector_nbytes): ...new function. Adjust users.
2250 (sweep_vectors): Adjust processing of large vectors.
2251 (allocate_vectorlike): Likewise.
2252 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2253 Add easserts. Adjust XSETPVECTYPESIZE usage.
2254 (allocate_buffer): Use BUFFER_PVEC_INIT.
2255 (live_vector_p): Adjust to match large vector.
2256 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2257 * buffer.h (struct buffer): Add next member.
2258 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2260 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

2263 * lread.c (defsubr): Use XSETPVECTYPE.
2264 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
2265 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
2266 (xvecsize): New command.
2268 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2270 * keyboard.c (event_to_kboard): Do not dereference
2271 frame_or_window field of SELECTION_REQUEST_EVENT
2272 and SELECTION_CLEAR_EVENT events (Bug#12814).
2273 * xterm.h (struct selection_input_event): Adjust comment.
2275 2012-11-07 Eli Zaretskii <eliz@gnu.org>
2277 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
2278 such as Scroll Lock, if the respective keys are treated as
2279 function keys, not as modifiers. This avoids destroying non-ASCII
2280 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
2282 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
2284 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
2286 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2288 Restore some duplicate definitions (Bug#12814).
2289 This undoes part of the 2012-11-03 changes. Some people build
2290 with plain -g rather than with -g3, and they need the duplicate
2291 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
2292 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
2293 Define as macros, as well as as enums or as constants.
2295 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
2297 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
2298 to keypad keys (Bug#12816).
2300 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
2302 Minor adjustments of recently-changed frame functions.
2303 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
2304 known to be a frame (we're in the FRAMEP branch).
2305 * lisp.h (Qframep): Remove decl. frame.h declares this.
2306 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
2307 since they're meant for Lisp fixnum values.
2309 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2311 * window.c (Fwindow_combination_limit): Revert to the only
2312 required argument and adjust docstring as suggested in
2313 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
2314 by Martin Rudalics <rudalics@gmx.at>.
2316 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2318 Widely used frame validity and checking functions.
2319 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.

2323 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
2324 (Fframe_pointer_visible_p): Use decode_any_frame.
2325 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
2326 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
2327 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
2328 (Fframe_focus): Likewise. Allow zero number of arguments.
2330 (frame_buffer_list, frame_buffer_predicate): Remove.
2331 * lisp.h (frame_buffer_predicate): Remove prototype.
2332 * buffer.c (Fother_buffer): Use decode_any_frame.
2333 * xdisp.c (Ftool_bar_lines_needed): Likewise.
2334 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
2335 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
2336 (Fclose_font, Ffont_info): Use decode_live_frame.
2337 * fontset.c (check_fontset_name): Likewise.
2338 * terminal.c (Fframe_terminal): Likewise.
2339 * w32fns.c (check_x_frame): Likewise.
2340 * window.c (Fminibuffer_window, Fwindow_at)
2341 (Fcurrent_window_configuration): Likewise.
2342 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
2343 Likewise. Allow zero number of arguments. Adjust docstring.
2344 * dispnew.c (Fredraw_frame): Likewise.
2345 * xfaces.c (frame_or_selected_frame): Remove.
2346 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
2347 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
2348 (Fframe_face_alist): Use decode_live_frame.
2349 * xfns.c (check_x_frame): Likewise.
2351 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
2353 * window.c (quad): New function.
2354 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
2355 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
2356 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
2357 (Fwindow_line_height): Use it.
2358 (Fwindow_fringes): Use list3.
2359 (Fwindow_scroll_bars): Use list4.
2360 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
2361 (Fwindow_combination_limit): Allow zero number of arguments.
2363 2012-11-05 Eli Zaretskii <eliz@gnu.org>
2365 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
2367 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
2368 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
2369 file descriptor 2 for standard error. (Bug#12805)
2371 2012-11-05 Chong Yidong <cyd@gnu.org>
2373 * process.c (wait_reading_process_output): Revert previous change.
2375 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
2377 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
2378 This removes code that has been obsolete since around 1990.
2379 * callproc.c (Fcall_process):
2381 * process.c (create_process):
2382 * term.c (dissociate_if_controlling_tty):
2383 Assume setsid exists.
2384 * callproc.c (child_setup): Assume setpgid exists and behaves as
2385 per POSIX.1-1988 or later.
2386 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
2387 * emacs.c (shut_down_emacs):
2388 * sysdep.c (sys_suspend, init_foreground_group):
2389 Assume getpgrp behaves as per POSIX.1-1998 or later.
2390 * msdos.c (setpgrp): Remove.
2391 (tcgetpgrp, setpgid, setsid): New functions.
2392 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
2393 * term.c (no_controlling_tty): Remove; unused.
2394 * w32proc.c (setpgrp): Remove.
2395 (setsid, tcgetpgrp): New functions.
2397 Simplify by assuming __fpending.
2398 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2399 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2400 Do not assume that __fpending's result fits in int.
2402 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2404 Remove EMACS_OUTQSIZE+sleep hack.
2405 * dispnew.c (update_frame_1): Remove hack for terminals slower
2406 than 2400 bps, which throttled Emacs by having it sleep.
2407 This code hasn't worked since at least 2007, when the multi-tty stuff
2408 was added, and anyway those old terminals are long dead.
2409 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2410 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2412 Fix data-loss with --version (Bug#9574).
2413 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2414 as we can't assume that emacs_strerror is initialized, and strerror
2415 is good enough here.
2416 (main): Invoke atexit earlier, to catch earlier instances of
2417 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2419 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2421 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2422 (keyDown): Remap keypad keys to X11 virtual key codes.
2424 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2426 Fix data-loss with --batch (Bug#9574).
2427 * emacs.c: Include <close-stream.h>.
2428 (close_output_streams): New function.
2429 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2430 and handles errors appropriately.
2431 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2434 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2435 The symptom is a diagnostic "GLib-WARNING **: In call to
2436 g_spawn_sync(), exit status of a child process was requested but
2437 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2438 waitpid(), so exit status can't be returned." The diagnostic
2439 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2440 The real bug is a race condition between Emacs and glib: Emacs
2441 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2442 so that glib can't find it. Work around the bug by invoking
2443 waitpid only on subprocesses that Emacs itself creates.
2444 * process.c (create_process, record_child_status_change):
2445 Don't use special value -1 in pid field, as the caller now must
2446 know the pid rather than having the callee infer it.
2447 The inference was sometimes incorrect anyway, due to another race.
2448 (create_process): Set new 'alive' member if child is created.
2449 (process_status_retrieved): New function.
2450 (record_child_status_change): Use it.
2451 Accept negative 1st argument, which means to wait for the
2452 processes that Emacs already knows about. Move special-case code
2453 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2454 processes that have already been waited for, by testing and
2455 clearing new 'alive' member.
2456 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2457 now does this internally.
2458 (handle_child_signal): Let record_child_status_change do all
2459 the work, since we do not want to reap all exited child processes,
2460 only the child processes that Emacs itself created.
2461 * process.h (Lisp_Process): New boolean member 'alive'.
2463 Omit duplicate definitions no longer needed with gcc -g3.
2464 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2465 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2466 Define only as macros. There's no longer any need to also define
2467 these symbols as enums or as constants, since we now assume
2468 gcc -g3 when debugging.
2470 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2472 * lisp.mk: Adjust comments to the fact that term/internal is now
2473 loaded from loadup.el.
2475 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2476 (msdos_fatal_signal): New function.
2477 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2480 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2481 for GCC versions before 4.
2482 (emacs_raise): Define to call msdos_fatal_signal.
2484 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2485 iterator when starting in the middle of a display or overlay
2488 2012-11-03 Chong Yidong <cyd@gnu.org>
2490 * process.c (wait_reading_process_output): Clean up the last
2493 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2495 * process.c (wait_reading_process_output): Avoid a race condition
2496 with SIGIO delivery (Bug#11536).
2498 2012-11-03 Chong Yidong <cyd@gnu.org>
2500 * buffer.c (cursor_type): Untabify docstring.
2502 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2504 * frame.h (struct frame): Drop can_have_scroll_bars member
2505 which is meaningless for a long time. Adjust comments.
2506 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2507 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2509 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2511 * window.c (decode_next_window_args): Update window arg after
2512 calling decode_live_window and so fix crash reported at
2513 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2514 by Juanma Barranquero <lekktu@gmail.com>.
2515 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2516 * font.c (Ffont_at): Likewise.
2518 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2520 * widget.c (resize_cb): New function.
2521 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2522 (EmacsFrameResize): Check if all is up to date before changing frame
2525 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2527 Implement backtrace output for fatal errors on MS-Windows.
2528 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2529 (BACKTRACE_LIMIT_MAX): New macro.
2530 (w32_backtrace): New function.
2531 (emacs_abort): Use w32_backtrace when the user chooses not to
2532 attach a debugger. Update the text of the abort dialog.
2534 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2536 Window-related stuff cleanup here and there.
2537 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2538 Use decode_any_window.
2539 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2540 * xdisp.c (Fformat_mode_line): Likewise.
2541 * font.c (Ffont_at): Use decode_live_window.
2542 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2543 * window.c (decode_next_window_args): Likewise.
2544 (decode_any_window): Remove static.
2545 * window.h (decode_any_window): Add prototype.
2546 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2547 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2550 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2552 Remove pad from struct input_event.
2553 * termhooks.h (struct input_event): Remove padding field.
2555 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2556 member is never cons for a long time. Adjust comment.
2557 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2558 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2559 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2560 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2562 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2564 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2566 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2568 Fix crash when using Emacs as commit editor for git (Bug#12697).
2569 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2570 and it is configured in conf_post.h.
2571 (Fcall_process): Don't invoke both setsid and setpgid; the former
2572 is enough, if it exists.
2573 * callproc.c (Fcall_process, child_setup):
2574 * process.c (create_process): Use setpgid.
2575 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2577 * dispnew.c (init_display): Initialize the foreground group
2578 if we are running a tty display.
2579 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2580 * lisp.h (init_foreground_group): New decl.
2581 * sysdep.c (inherited_pgroup): New static var.
2582 (init_foreground_group, tcsetpgrp_without_stopping)
2583 (narrow_foreground_group, widen_foreground_group): New functions.
2584 (init_sys_modes): Narrow foreground group.
2585 (reset_sys_modes): Widen foreground group.
2587 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2589 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2591 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2593 * minibuf.c (read_minibuf): Restore current buffer since
2594 choose_minibuf_frame calling Fset_frame_selected_window may
2595 change it (Bug#12766).
2597 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2599 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2601 2012-10-30 Kenichi Handa <handa@gnu.org>
2603 * font.c (Ffont_at): If WINDOW is specified and it is not
2604 displaying the current buffer, signal an error.
2606 2012-10-29 Daniel Colascione <dancol@dancol.org>
2608 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2609 In preparation for fixing bug#12739, move these functions from
2612 * coding.h, coding.c: ... to here, and compile them only when
2613 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2614 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2616 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2618 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2619 (timer_loop, getitimer, setitimer): Use it instead of
2620 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2622 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2625 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2627 * nsterm.m (NO_APPDEFINED_DATA): New define.
2628 (last_appdefined_event_data): New variable
2629 (last_appdefined_event): Remove.
2630 (ns_select): Initialize t from last_appdefined_event_data instead
2631 of [last_appdefined_event data1].
2632 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2633 remove last_appdefined_event (Bug#12698).
2635 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2637 * frame.c (x_set_font): Catch internal error.
2639 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2641 Avoid overflow in w32 implementation of interval timers.
2642 When possible, for ITIMER_PROF count only times the main thread
2644 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2645 'volatile ULONGLONG' types. All the other data which was
2646 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2647 (GetThreadTimes_Proc): New typedef.
2648 (w32_get_timer_time): New function, returns a suitable time value
2650 (timer_loop): Enter critical section when accessing ULONGLONG
2651 values of the itimer_data struct, as these accesses are no longer
2652 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2653 Remove unused variable.
2654 (init_timers): Initialize s_pfn_Get_Thread_Times.
2655 (start_timer_thread): Don't assign itimer->caller_thread here.
2656 (getitimer): Assign itimer->caller_thread here.
2657 (setitimer): Always call getitimer to get the value of ticks_now.
2658 (sys_spawnve): Avoid compiler warning about format mismatch.
2660 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2662 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2663 mouse movement events if the menu bar is active. This avoids
2664 producing a busy "hour-glass" cursor by Windows if the mouse
2665 pointer is positioned over a tooltip shown for some menu item.
2667 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2669 Don't assume process IDs fit in int.
2670 * emacs.c (shut_down_emacs) [!DOS_NT]:
2671 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2672 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2673 Use pid_t, not int, to store process IDs, as 'int'
2674 is not wide enough on a few platforms (e.g., AIX and IRIX).
2676 2012-10-23 Kenichi Handa <handa@gnu.org>
2678 The following change is to make face-font-rescale-alist work
2679 correctly for non-ASCII fonts.
2681 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2682 (font_open_for_lface): Handle Vface_font_rescale_alist.
2684 2012-10-23 Chong Yidong <cyd@gnu.org>
2686 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2688 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
2690 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
2692 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2694 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2697 2012-10-21 Glenn Morris <rgm@gnu.org>
2699 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2701 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2703 Port to OpenBSD 5.1.
2704 * frame.c (Fmouse_position, Fmouse_pixel_position):
2705 * xdisp.c (produce_stretch_glyph):
2706 Declare local vars only when they're needed.
2707 This is clearer and avoids a warning on OpenBSD about unused vars.
2708 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2709 This is safer, and avoids OpenBSD warnings about unused vars.
2710 * keyboard.c (record_menu_key): Remove unnecessary decl.
2711 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2712 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2713 as our definition clashes with OpenBSD's.
2714 * xfaces.c (load_face_colors, check_lface_attrs)
2715 (get_lface_attributes_no_remap, get_lface_attributes)
2716 (lface_fully_specified_p, x_supports_face_attributes_p)
2717 (tty_supports_face_attributes_p, face_fontset, realize_face)
2718 (realize_x_face, realize_tty_face):
2719 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2720 merely Lisp_Object *. This is more informative and avoids
2721 a warning on OpenBSD about accessing beyond an object's size.
2723 2012-10-20 Chong Yidong <cyd@gnu.org>
2725 * lread.c (Fload): Doc fix (Bug#12592).
2727 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2729 * font.c (Ffont_at): Fix previous change.
2731 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2733 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2734 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
2737 * alloc.c (NSTATICS): Decrease to 0x800.
2739 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
2741 * fns.c (Fnreverse): Include the problem element when signaling an
2744 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
2746 * nsterm.m (ns_select): Check writefds before call to
2747 FD_ISSET (Bug#12668).
2749 2012-10-18 Daniel Colascione <dancol@dancol.org>
2751 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2752 (staticpro): If we run out of staticpro slots, die with an
2753 informative error instead of just calling emacs_abort.
2755 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2757 Fix two flaws reported by Dmitry Antipov.
2758 * window.c (Ftemp_output_buffer_show): Remove.
2759 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
2760 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
2762 2012-10-17 Eli Zaretskii <eliz@gnu.org>
2764 * makefile.w32-in ($(BLD)/w32.$(O)):
2765 ($(BLD)/vm-limit.$(O)):
2767 ($(BLD)/unexw32.$(O)):
2768 ($(BLD)/fileio.$(O)):
2769 ($(BLD)/dispnew.$(O)): Update dependencies.
2771 * w32term.h (w32_initialize_display_info, initialize_w32_display):
2774 * w32proc.c: Include ctype.h.
2776 * w32.h (init_environment, check_windows_init_file)
2777 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
2778 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
2779 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
2780 (sys_link): Add prototypes.
2782 * w32.c: Include w32select.h.
2783 (sys_access, e_malloc, sys_select): Add prototypes.
2784 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
2786 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
2788 * unexw32.c: Include lisp.h and w32.h.
2790 * term.c [WINDOWSNT]: Include w32term.h.
2792 * process.c [WINDOWSNT]: Add prototype of sys_select.

2854 * image.c (init_tiff_functions, init_imagemagick_functions)
2855 (init_svg_functions): Fix cygw32 build break by using these
2856 functions only when WINDOWSNT _and_ HAVE_NTGUI.

2877 Fix some stat-related races.
2878 * fileio.c (Fwrite_region): Avoid race condition if a file is

2911 * fileio.c (check_existing): New function.
2912 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
2913 instead of calling 'stat', when what's needed is to check whether
2914 a file exists. This avoids expensive system calls on MS-Windows.
2917 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
2919 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

3010 * process.c (wait_reading_process_output):
3011 Use unsigned for counter where wraparound-on-overflow is desired,
3012 since unsigned is guaranteed to have that behavior and signed is not.
3013 (read_char): Use ptrdiff_t for string length.
3014 (get_input_pending): Remove first argument, since it was always
3015 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3016 and behave as if it had that value. Return new value of
3017 input_pending. All callers changed.
3018 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3019 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
3021 * keymap.c (push_key_description): Omit last arg, which was always 1.
3022 All callers changed.
3024 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
3026 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

3042 Don't include termopts.h.
3044 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
3046 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3048 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3050 * commands.h (immediate_quit): Remove duplicate decl.
3052 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3054 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

3057 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3059 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3061 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3062 match what GetLastError returns. Explain why the function is
3065 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3066 'is_tooltip_frame', to avoid confusion with its global namesake.
3068 2012-10-08 Daniel Colascione <dancol@dancol.org>
3070 * xdisp.c (start_hourglass): Call w32_note_current_window when
3071 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3072 build that caused Emacs to display the hourglass cursor forever.
3074 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3075 which is broken under remote desktop, calculate the number of
3076 colors available for a display based on the display's number of
3077 planes and number of bits per pixel per plane. (bug#10397).
3079 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3081 * nsfont.m (Vfonts_in_cache): New variable.
3082 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3083 are used. Add cached fonts to Vfonts_in_cache.
3084 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3086 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3088 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3090 (FONT_H): Define after FRAME_H.
3091 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3092 Update dependencies.
3094 * w32term.c: Remove leftover declaration of keyboard_codepage.
3096 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3098 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3099 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3100 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
3101 (GLOBAL_SOURCES): Add cygw32.c.
3102 ($(BLD)/unexw32.$(O)):
3104 ($(BLD)/w32console.$(O)):
3105 ($(BLD)/w32fns.$(O)):
3106 ($(BLD)/w32heap.$(O)):
3107 ($(BLD)/w32menu.$(O)):
3108 ($(BLD)/w32proc.$(O)): Add w32common.h.
3110 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3112 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3114 2012-10-08 Daniel Colascione <dancol@dancol.org>
3116 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3117 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3118 accidental message numbering hole. Change other messages to
3121 * w32select.h (HAVE_W32SELECT): Remove.
3123 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3124 w32common.h instead of w32heap.h.
3126 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
3127 (get_allocation_unit, get_processor_type, get_w32_major_version)
3128 (get_w32_minor_version, sysinfo_cache, osinfo_cache)

3130 (OS_NT, os_subtype, cache_system_info): Move declarations to
3133 * w32heap.c: Include w32common.h.
3134 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3135 (w32_minor_version, w32_build_number, w32_subtype):
3136 Remove duplicate definitions.
3138 * w32fns.c: Include w32common.h; include w32heap.h only in
3141 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3142 Use `report_file_error' instead of `error' in order to better
3143 inform users of what went wrong. Increase NTGUI_UNICODE file
3144 dialog box file name length to 32k, the maximum allowed by the NT
3147 * w32common.h: New file.
3148 (ROUND_UP, ROUND_DOWN, get_page_size)
3149 (get_allocation_unit, get_processor_type, get_w32_major_version)
3150 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3151 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3152 (OS_NT, os_subtype, cache_system_info): Move here.
3154 * unexw32.c, unexcw.c: Include w32common.h.
3156 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3157 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3158 to call syms_of_w32select.
3160 * cygw32.h: Remove obsolete EXFUN declarations.
3162 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

3165 of w32inevt.o from SOME_MACHINE_OBJECTS.
3167 2012-10-08 Daniel Colascione <dancol@dancol.org>
3169 * image.c: Permanent fix for JPEG compilation issue --- limit
3170 jpeglib `boolean' redefinition to Cygwin builds.
3172 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3174 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3176 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3179 2012-10-08 Daniel Colascione <dancol@dancol.org>
3181 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3182 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3183 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3184 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3185 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3186 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3187 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3188 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3189 now a supported configuration.
3191 * Makefile.in: consolidate image variables into LIBIMAGE; add
3192 W32_OBJ and W32_LIBS. Compile new files.
3195 (_DebPrint) declare tracing facility for W32 debugging. We need
3196 to unify tracing later.
3198 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3199 unconditional use of W32 Unicode functions. Cygwin runs only on
3200 100% Unicode operating systems.
3202 * cygw32.c: New file. Define Cygwin-specific facilities.
3203 (Fcygwin_convert_path_to_windows)
3204 (Fcygwin_convert_path_from_windows): New user functions for
3205 accessing Cygwin path-munging routines.
3207 * cygw32.h: New file.
3208 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3209 UTF-16LE strings temporarily inside non-Lisp-visible string
3212 (w32_strerror): Just what it says on the tin.
3214 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3215 also run for Cygwin; both systems have the same problem with using
3216 GUI facilities in a forked child. Also call syms_of_cygw32,
3217 syms_of_w32select in correct places.
3219 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3220 needs fork-then-exec for daemon launching.
3222 * font.h: Include frame.h.
3224 * image.c: Use the image library cache machinery only when we're
3225 compiling for native WINDOWSNT; Cygwin can use shared libraries
3226 like any other Unixlike system.
3228 * keyboard.c: Clarify a comment regarding the input loop.
3230 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3231 functions directly instead of trying to detect at runtime that our
3232 host operating system supports them. We make this change for two
3233 reasons: Cygwin lacks support for the multibyte character
3234 conversion functions used by the legacy menu code, and Cygwin
3235 never needs to rely on non-Unicode APIs.
3237 * unexw32.c (hinst): Declare extern.
3239 * w32.c: Change header order;
3240 (w32_strerror): Move to w32fns.c because we need it for
3241 non-WINDOWSNT builds.
3243 * w32.h: Add #error macro to make sure we don't include w32.h for
3244 Cygwin builds. Remove w32select declarations.
3246 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3247 w32fns.c. w32console.c is WINDOWSNT-only.
3249 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3250 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3252 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3253 (w32_major_version, w32_minor_version, w32_build_number)
3254 (os_subtype, sound_type): Define here
3255 (w32_defined_color): Make color parameter const for consistency
3256 with other _defined_color functions.
3257 (w32_createwindow): Unconditionally call w32_init_class instead of
3258 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3259 through the code is complex and unnecessary because class
3260 registration is practically free.
3261 (w32_name_of_message): New EMACSDEBUG-only function.
3262 (Fset_message_beep): Move here
3263 (Fx_open_connection): Require that the display name for Windows be
3264 "w32" for consistency, emacsclient disambiguation, and maybe, one
3265 day, multi-window-system support.
3266 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
3267 Cygwin files for W32 GUI facilities, since these clearly don't

3282 (w32_console_toggle_lock_key): Move to w32fns.c.
3284 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.

3293 descriptor the system used to tell us about pending thread
3296 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
3297 that prevented compilation under non-WINDOWSNT systems.
3299 (w32_initialize): Open /dev/windows and assign it to
3300 w32_message_fd. Provide w32 feature.
3302 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
3303 (WM_EMACS_INPUT_READY): add.
3304 (prepend_msg, w32_message_fd): Declare globally.
3307 (keyboard_handle): Use only when WINDOWSNT.
3308 (notify_msg_ready): New function. Posts a message to the main
3309 thread's message queue under CYGWIN, which wakes up the main
3310 thread from select(2) by making the /dev/windows file descriptor
3311 ready. Under WINDOWSNT, it sets an event the same way the old
3314 (post, prepend_msg): Actually call notify_msg_ready instead of
3315 setting the input event directly.
3317 2012-10-07 Eli Zaretskii <eliz@gnu.org>
3319 * ralloc.c (relinquish): If a heap is ready to be relinquished,
3320 but it still has blocs in it, don't return it to the system,
3321 instead of aborting. (Bug#12402)
3323 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
3325 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).

3358 Improve sys_siglist detection.
3359 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
3360 defined as a macro, as is done in Solaris.
3361 (sys_siglist_entries): New macro.
3362 (save_strsignal): Use it.
3363 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
3364 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
3366 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
3368 * nsfns.m (Fx_create_frame): Call x_default_parameter with
3369 fullscreen/Fullscreen.
3371 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
3372 tobar_height is new.
3374 * nsterm.m (x_make_frame_visible): Check for fullscreen.
3375 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
3376 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

3387 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
3389 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
3391 2012-10-05 Eli Zaretskii <eliz@gnu.org>
3393 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
3395 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3396 that time stamps of directories could also be changed.
3397 Don't request the too broad GENERIC_WRITE, only the more restrictive
3398 FILE_WRITE_ATTRIBUTES access rights.
3400 * fileio.c (Fset_file_times): Special-case ignoring errors for
3401 directories only on MSDOS, not on MS-Windows.
3403 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3405 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3407 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3409 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3410 see whether CreateFile failed.
3412 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3414 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3415 to avoid similar races.
3416 * keyboard.c (pending_signals): Now bool, not int.
3418 Port timers to OpenBSD, plus check for timer failures.
3419 OpenBSD problem reported by Han Boetes.
3420 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3422 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3423 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3424 like OpenBSD, which has timer_settime but does not declare it.
3425 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3426 whether to use itimerspec-related primitives. All uses of
3427 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3429 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3431 * profiler.c (handle_profiler_signal): Fix a malloc race
3432 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3434 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3436 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3438 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3440 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3441 consistent with the change in return value of 'safe_strsignal'.
3443 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3445 Prefer plain 'static' to 'static inline' (Bug#12541).

3447 (bidi_set_sor_type, bidi_push_embedding_level)
3448 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

3453 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3454 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3455 Now 'static', not 'static inline'.
3457 Count overruns when profiling; change units to ns.
3458 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3459 Give extra weight to samples after overruns, to attempt to count
3460 the time more accurately.
3461 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3462 the underlying primitives nominally do ns.
3463 (Fprofiler_cpu_start): Document the change. Mention that
3464 the sampling intervals are only approximate.
3466 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3468 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3470 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3471 case for the special 0 coding-system.
3473 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3474 (Fmake_overlay): Remove redundant tests.
3475 (fix_start_end_in_overlays): Remove redundant recentering.
3477 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3479 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3480 Update dependencies.
3482 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3484 Fix a malloc race condition involving strsignal.
3485 A signal can arrive in the middle of a malloc, and Emacs's signal
3486 handler can invoke strsignal, which can invoke malloc, which is
3487 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3488 Fix it by altering the signal handler so that it does not invoke
3490 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3491 * process.c (status_message): Use const pointer, in case strsignal
3492 is #defined to safe_strsignal.
3493 * sysdep.c (sys_siglist, init_signals): Always define and
3494 initialize a substitute sys_siglist if the system does not define
3495 one, even if HAVE_STRSIGNAL.
3496 (safe_strsignal): Rename from strsignal. Always define,
3497 using sys_siglist. Return a const pointer.
3498 * syssignal.h (safe_strsignal): New decl.
3499 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3501 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3503 * w32proc.c (timer_loop): Fix code that waits for timer
3504 expiration, to avoid high CPU usage.
3506 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3508 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3509 (sweep_weak_table): Remove redundant prototypes.
3511 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3513 * emacs.c: Move the inclusion of TERM_HEADER after including
3514 windows.h on WINDOWSNT. This avoids compilation problems with
3517 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3519 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3520 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3521 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3522 as the previous version used 'void *'.
3524 * ralloc.c (ROUNDUP): Fix last change.
3525 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3528 * w32proc.c <disable_itimers>: New static flag.
3529 (init_timers): Initialize it to zero, after creating the critical
3530 sections used by the timer threads.
3531 (term_timers): Set to 1 before deleting the critical sections.
3532 (getitimer, setitimer): If disable_itimers is non-zero, return an
3533 error indication without doing anything. Reported by Fabrice
3534 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3535 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3537 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3540 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3541 term_ntproc after all the other bookkeeping, to get timers working
3542 as long as possible.
3544 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3546 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3547 Suggested by Juri Linkov in
3548 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3550 Prefer plain 'static' to 'static inline' (Bug#12541).
3551 With static functions, modern compilers inline pretty well by
3552 themselves; advice from programmers often hurts as much as it helps.
3553 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3554 this change shrinks the text size of the Emacs executable by 1.1%
3555 without affecting CPU significantly in my benchmark.
3556 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3636 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3638 Revert the FOLLOW-SYMLINKS change for file-attributes.
3639 Doing it right would require several changes to Tramp, and there's
3640 not enough time to get that tested before the freeze today.
3641 * dired.c (directory_files_internal, Ffile_attributes):
3644 * frame.c (x_report_frame_params): Port better to wider ints.
3645 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3646 or that pointers can be printed in 15 decimal digits.
3647 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

3828 Suggested by Eli Zaretskii in
3829 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
3831 2012-09-30 Eli Zaretskii <eliz@gnu.org>
3833 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
3834 HAVE_TIMER_SETTIME is defined.
3836 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
3838 Profiler improvements: more-accurate timers, overflow checks.
3839 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
3840 signal.h, setjmp.h. Include systime.h instead.
3841 (saturated_add): New function.

3848 All uses changed to store the new value.
3849 (handle_profiler_signal): Rename from sigprof_handler_1,
3850 for consistency with other handlers. Do not check whether
3851 cpu_log is a hash-table if garbage collecting, since it
3852 doesn't matter in that case.

3854 for consistency with other handlers.
3855 (setup_cpu_timer): New function, with much of what used to be in
3856 Fprofiler_cpu_start. Check for out-of-range argument.
3857 Prefer timer_settime if available, and prefer
3858 thread cputime clocks, then process cputime clocks, then
3859 monotonic clocks, to the old realtime clock. Use make_timeval
3860 to round more-correctly when falling back to setitimer.
3861 (Fprofiler_cpu_start): Use it.
3862 (Fprofiler_cpu_stop): Prefer timer_settime if available.
3863 Don't assume that passing NULL as the 2nd argument of setitimer

3866 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
3867 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
3868 non-fatal signal handlers. Ignore SIGPROF on startup.
3869 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
3870 in profiler.c, since sysdep.c now uses it.
3872 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

3927 * charset.c, charset.h (maybe_unify_char): Now static.
3928 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
3929 Since this stuff is now private to charset.c, there's no need for
3930 a public macro and no need to inline by hand.

4002 (sigaction): Rewrite to call sys_signal instead of duplicating its
4004 (sys_kill): Improve commentary.
4006 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4007 consistency with a signature of a signal handler. All callers
4009 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4010 install term_ntproc as a signal handler for SIGABRT, as that
4011 should be done by the dumped Emacs.
4013 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4015 * w32select.c (term_w32select): Protect against repeated
4016 invocation by setting clipboard_owner to NULL after calling

4134 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4135 fatal_error_backtrace.

4153 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4154 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4155 wanted even on POSIXish hosts, and it doesn't work on Windows.
4157 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4159 * xterm.c (x_term_init): Call fixup_locale before and after calling
4160 gtk_init (Bug#12392).
4162 2012-09-23 Chong Yidong <cyd@gnu.org>
4164 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4165 Vdynamic_library_alist.
4167 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4168 (Fgnutls_available_p): Caller changed.
4170 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4171 (Flibxml_parse_xml_region): Likewise.
4173 * dispextern.h (struct image_type): Remove arg from init function.
4175 * image.c (Finit_image_library, lookup_image_type)
4176 (define_image_type): Remove now-unneeded second arg.
4177 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4178 (init_tiff_functions, init_gif_functions, init_svg_functions):
4179 Arglist and w32_delayed_load calling convention changed.
4180 (gs_type): Remove init_gs_functions; there is no such function.
4181 (valid_image_p, make_image): Fix caller to lookup_image_type.
4183 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4185 Simplify and avoid signal-handling races (Bug#12471).
4187 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4188 Avoid recursive loop if there's a fatal error in the function itself.
4189 * atimer.c (pending_atimers):
4190 * blockinput.h: Don't include "atimer.h"; no longer needed.
4191 (interrupt_input_pending): Remove. All uses removed.
4192 pending_signals now counts both atimers and ordinary interrupts.
4193 This is less racy than having three separate pending-signal flags.
4194 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4196 Rename from their upper-case counterparts BLOCK_INPUT,
4197 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4198 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4199 This makes it easier to access volatile variables more accurately.
4200 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4201 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4202 that's more reliable if the code is buggy and sets
4203 interrupt_input_blocked to a negative value. All uses changed.
4204 * atimer.c (deliver_alarm_signal):
4205 Remove. No need to deliver this to the parent; any thread can
4206 handle this signal now. All uses replaced by underlying handler.
4207 * atimer.c (turn_on_atimers):
4208 * dispnew.c (handle_window_change_signal):
4209 * emacs.c (handle_danger_signal):
4210 * keyboard.c (kbd_buffer_get_event):
4211 Don't reestablish signal handler; not needed with sigaction.
4212 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4214 Rework to avoid unnecessary accesses to volatile variables.
4215 (UNBLOCK_INPUT_TO): Now a function.
4216 (totally_unblock_input, unblock_input): New decls.
4217 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4218 (init_data): Remove. Necessary stuff now done in init_signal.
4219 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4220 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4221 (fatal_error_code): Remove; no longer needed.
4222 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4223 it doesn't always backtrace. All uses changed. No need to reset
4224 signal to default, since sigaction and/or die does that for us now.
4225 Use emacs_raise (FOO), not kill (getpid (), FOO).
4226 (main): Check more-accurately whether we're dumping.
4227 Move fatal-error setup to sysdep.c
4228 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4229 * gtkutil.c (xg_get_file_name, xg_get_font):
4230 Remove no-longer-needed signal-mask manipulation.
4231 * keyboard.c, process.c (POLL_FOR_INPUT):
4232 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4233 * keyboard.c (read_avail_input): Remove.
4234 All uses replaced by gobble_input.
4235 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4236 (kbd_buffer_store_event_hold, gobble_input):
4237 (record_asynch_buffer_change) [USABLE_SIGIO]:
4238 (store_user_signal_events):
4239 No need to mess with signal mask.
4240 (gobble_input): If blocking input and there are terminals, simply
4241 set pending_signals to 1 and return. All hooks changed to not
4242 worry about whether input is blocked.
4243 (process_pending_signals): Clear pending_signals before processing
4244 them, in case a signal comes in while we're processing.
4245 By convention callers now test pending_signals before calling us.
4246 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4247 New functions, to support changes to blockinput.h.
4248 (handle_input_available_signal): Now extern.
4249 (reinvoke_input_signal): Remove. All uses replaced by
4251 (quit_count): Now volatile, since a signal handler uses it.
4252 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4253 All callers changed. Block SIGINT only if not already blocked.
4254 Clear sigmask reliably, even if Fsignal returns, which it can.
4255 Omit unnecessary accesses to volatile var.
4256 (quit_throw_to_read_char): No need to restore sigmask.
4257 * keyboard.c (gobble_input, handle_user_signal):
4258 * process.c (wait_reading_process_output):
4259 Call signal-handling code rather than killing ourselves.
4260 * lisp.h: Include <float.h>, for...
4261 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4262 (pending_signals): Now volatile.
4263 (syms_of_data): Now const if IEEE floating point.
4264 (handle_input_available_signal) [USABLE_SIGIO]:
4265 (terminate_due_to_signal, record_child_status_change): New decls.
4266 * process.c (create_process): Avoid disaster if memory is exhausted
4267 while we're processing a vfork, by tightening the critical section
4269 (send_process_frame, process_sent_to, handle_pipe_signal)
4270 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
4272 (send_process): No need for setjmp/longjmp any more, since the
4273 SIGPIPE stuff is now gone. Instead, report an error if errno
4275 (record_child_status_change): Now extern. PID and W are now args.
4276 Return void, not bool. All callers changed.
4277 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
4278 Remove. All uses removed. This bug should be fixed now in a
4280 (wait_for_termination_1): Use waitpid rather than sigsuspend,
4281 and record the child status change directly. This avoids the
4282 need to futz with the signal mask.
4283 (process_fatal_action): Move here from emacs.c.
4284 (emacs_sigaction_flags): New function, containing
4285 much of what used to be in emacs_sigaction_init.
4286 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
4287 caught by emacs, to make races less likely.
4288 (deliver_process_signal): Rename from handle_on_main_thread.
4290 (BACKTRACE_LIMIT_MAX): Now at top level.
4291 (thread_backtrace_buffer, threadback_backtrace_pointers):
4293 (deliver_thread_signal, deliver_fatal_thread_signal):
4294 New functions, for more-accurate delivery of thread-specific signals.
4295 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
4296 (deliver_arith_signal): Handle in this thread, not
4297 in the main thread, since it's triggered by this thread.
4298 (maybe_fatal_sig): New function.
4299 (init_signals): New arg DUMPING so that we can be more accurate
4300 about whether we're dumping. Caller changed.
4301 Treat thread-specific signals differently from process-general signals.
4302 Block all signals while handling fatal error; that's safer.
4303 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
4305 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
4306 Ignore SIGPIPE unless batch.
4307 (emacs_backtrace): Output backtrace for the appropriate thread,
4308 which is not necessarily the main thread.
4309 * syssignal.h: Include <stdbool.h>.
4310 (emacs_raise): New macro.
4311 * xterm.c (x_connection_signal): Remove; no longer needed
4312 now that we use sigaction.
4313 (x_connection_closed): No need to mess with sigmask now.
4314 (x_initialize): No need to reset SIGPIPE handler here, since
4315 init_signals does this for us now.
4317 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4319 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
4320 background rect may be larger (Bug#12245).
4322 2012-09-23 Chong Yidong <cyd@gnu.org>
4324 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
4326 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4328 * .gdbinit: Just stop at fatal_error_backtrace.
4329 See Stefan Monnier's request in
4330 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
4331 Remove no-longer-used query of system type.
4333 2012-09-22 Chong Yidong <cyd@gnu.org>
4335 * search.c (Freplace_match): Doc fix (Bug#12325).
4337 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
4339 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
4340 (Fline_end_position): Doc fix.
4342 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
4344 2012-09-22 Chong Yidong <cyd@gnu.org>
4346 * dispextern.h (struct image_type): Add new slot, storing a type
4347 initialization function.
4349 * image.c (define_image_type): Call the image initializer function
4350 if it is defined. Arguments and return value changed.
4351 (valid_image_p, make_image): Callers changed.
4352 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
4353 (gif_type, imagemagick_type, svg_type, gs_type):
4354 Add initialization functions.
4355 (Finit_image_library): Call lookup_image_type.
4356 (CHECK_LIB_AVAILABLE): Macro deleted.
4357 (lookup_image_type): Call define_image_type here, rather than via
4358 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
4359 (syms_of_image): Move define_image_type calls for xbm_type and
4360 pbm_type to lookup_image_type.
4362 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4364 * keyboard.c (timer_check_2): Move calculation of 'timers' and
4365 'idle_timers' from here ...
4366 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
4367 lists, to avoid infloops when the timer does something stupid,
4368 like reinvoke itself with the same or smaller time-out.
4371 2012-09-22 Martin Rudalics <rudalics@gmx.at>
4373 * window.c (Fsplit_window_internal): Handle only Qt value of
4374 Vwindow_combination_limit separately.
4375 (Qtemp_buffer_resize): New symbol.
4376 (Vwindow_combination_limit): New default value.
4379 2012-09-22 Eli Zaretskii <eliz@gnu.org>
4381 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
4382 the new overlay string. (Bug#10159)
4384 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
4386 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
4387 or that fprintf is async-signal-safe. POSIX doesn't require
4390 2012-09-22 Chong Yidong <cyd@gnu.org>
4392 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
4395 2012-09-22 Kenichi Handa <handa@gnu.org>
4397 * composite.c (composition_reseat_it): Handle the case that a
4398 grapheme cluster is not covered by a single font (Bug#12352).
4400 2012-09-21 Chong Yidong <cyd@gnu.org>
4402 * image.c (define_image_type): Avoid adding duplicate types to
4403 image_types (Bug#12463). Suggested by Jörg Walter.
4405 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4407 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4408 (print_load_command_name): Add case LC_DATA_IN_CODE.
4409 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4411 2012-09-21 Glenn Morris <rgm@gnu.org>
4413 * eval.c (Frun_hook_with_args_until_success)
4414 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4416 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4418 * fileio.c (Ffile_selinux_context): Only call freecon when
4419 lgetfilecon succeeded.
4420 (Fset_file_selinux_context): Likewise. (Bug#12444)
4422 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4424 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4425 reordering, locate the cursor by calling set_cursor_from_row; if
4426 that fails, clear the desired glyph matrix before returning a
4427 failure indication to the caller. Fixes leaving garbled display
4428 when fast scrolling with a down-key. (Bug#12403)
4429 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4430 scrolling through multibyte text.
4432 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4434 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4435 calling mark_vectorlike since that's the one that marks the window.
4436 (mark_discard_killed_buffers): Mark the final cdr.
4437 * window.h (struct window): Move prev/next_buffers to the
4438 non-standard fields.
4439 * window.c (make_window): Initialize prev/next_buffers manually.
4441 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4443 Omit unused arg EXPECTED from socket hooks.
4444 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4445 * nsterm.m (ns_term_init):
4446 * termhooks.h (struct terminal.read_socket_hook):
4447 * w32inevt.c (w32_console_read_socket):
4448 * w32term.c (w32_read_socket):
4449 * xterm.c (XTread_socket):
4450 Omit unused arg EXPECTED. All callers changed.
4451 (store_user_signal_events): Return void, not int, since callers no
4452 longer care about the return value. All uses changed.
4454 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4456 * w32gui.h (XParseGeometry): Do not declare.
4458 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4460 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4461 Ignore 'expected'. See Eli Zaretskii in
4462 <http://bugs.gnu.org/12471#8> (last line).
4464 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4465 (XParseGeometry): Now static. Substitute extremal values for
4466 values that are out of range.
4468 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4470 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4472 * nsfns.m (XParseGeometry): Remove.
4473 (Fx_create_frame): Call x_set_offset to correctly interpret
4474 top_pos in geometry.
4476 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4477 (Fx_parse_geometry): If there is a space in string, call
4478 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4480 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4482 * search.c (scan_buffer): Use character positions in calls to
4483 region_cache_forward and region_cache_backward, not byte
4484 positions. (Bug#12196)
4486 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4487 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4489 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4490 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4491 emacs_blocked_malloc, now deleted.
4493 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4495 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4496 The workaround was for improving performance on Solaris 2.4, but
4497 is getting in the way now. Emacs will still work if someone is
4498 still running Solaris 2.4 in a museum somewhere; Sun dropped
4499 support for Solaris 2.4 in 2003.
4500 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4501 * process.c (create_process) [HAVE_WORKING_VFORK]:
4502 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4503 since Emacs no longer uses vfork on that platform.
4505 2012-09-17 Glenn Morris <rgm@gnu.org>
4507 * emacs.c: Use COPYRIGHT.
4509 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4511 Remove configure's --without-sync-input option (Bug#12450).
4512 When auditing signal-handling in preparation for cleaning it up,
4513 I found that SYNC_INPUT has race conditions and would be a real
4514 pain to fix. Since it's an undocumented and deprecated
4515 configure-time option, now seems like a good time to remove it.
4516 Also see <http://bugs.gnu.org/11080#16>.
4517 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4518 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4519 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4520 (malloc_hysteresis):
4521 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4522 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4523 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4524 (dont_register_blocks, bytes_used_when_reconsidered)
4525 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4526 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4527 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4528 Remove. All uses removed.
4529 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4530 implementation, one that depends on whether the new macro
4531 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4533 * atimer.c (run_timers, handle_alarm_signal):
4534 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4535 (handle_async_input, process_pending_signals)
4536 (handle_input_available_signal, init_keyboard):
4537 * nsterm.m (ns_read_socket):
4538 * process.c (wait_reading_process_output):
4539 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4540 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4542 * xterm.c (XTread_socket):
4544 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4545 * eval.c (handling_signal): Remove. All uses removed.
4546 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4547 All uses replaced with the SYNC_INPUT version.
4548 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4550 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4553 * font.c (Ffont_shape_gstring): Remove unused local.
4555 2012-09-16 Glenn Morris <rgm@gnu.org>
4557 * Makefile.in (clean): No longer run nextstep's clean.
4559 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4561 (ns-app): Move here from ns.mk, and simplify.
4562 (clean): Simplify nextstep entry.
4563 * ns.mk: Remove file.
4565 2012-09-17 Kenichi Handa <handa@gnu.org>
4567 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4568 not covert the last few charactes.
4570 2012-09-16 Kenichi Handa <handa@gnu.org>
4572 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4573 here, but just check the validity of glyphs in the glyph-string.
4575 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4577 * window.c (Fwindow_parameter, Fset_window_parameter):
4578 Accept any window as argument (Bug#12452).
4580 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4582 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4583 to ns_term_init to avoid memory leak.
4585 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4586 explicit retain/release.
4587 (ns_term_init): Only allow one display. Initialize outerpool and
4590 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4592 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4593 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4594 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4595 the Microsoft problem in a different way, by altering ../nt/config.nt.
4597 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4612 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4613 by lisp.h. This completes removal of setjmp.h inclusion
4614 erroneously announced in the previous commit. (Bug#12446)
4616 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4619 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4620 not defined as a macro. The latter happens on MS-Windows.
4623 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4625 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4626 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4627 Some instances of '#include <setjmp.h>' removed, if the
4628 only reason for the instance was because "lisp.h" was included.
4629 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4630 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4631 and _longjmp with the new symbols. Emacs already uses _setjmp if
4632 available, so this change affects only POSIXish hosts that have
4633 sigsetjmp but not _setjmp, such as some versions of Solaris and
4634 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4635 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4636 (png_load_body) [HAVE_PNG]:
4637 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4638 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4639 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4640 since PNG requires jmp_buf. This is the only exception to the
4641 general rule that we now use sys_setjmp and sys_longjmp.
4642 This exception is OK since this code does not change the signal
4643 mask or longjmp out of a signal handler.
4645 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4647 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4648 Include "syssignal.h", for 'main_thread'.
4650 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4652 Avoid out-of-range marker position (Bug#12426).
4653 * insdel.c (replace_range, replace_range_2):
4654 Adjust markers before overlays, as suggested by comments.
4655 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4656 Remove redundant check before calling offset_intervals.
4658 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4660 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4661 current buffer (Bug#12387).
4663 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4665 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4667 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4669 Use a more backwards-compatible timer format (Bug#12430).
4670 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4671 vector element, not from the 4th, since PSECS is now at the end.
4672 (Fcurrent_idle_time): Doc fix.
4674 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4676 Function to mark objects and remove killed buffers at once.
4677 * alloc.c (discard_killed_buffers): Rename to ...
4678 (mark_discard_killed buffers) ... new name. Add marking
4679 of remaining objects. Fix comment. Adjust users.
4680 (mark_object): Do not touch frame buffer lists here.
4681 * frame.c (delete_frame): Reset frame buffer lists here.
4683 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4685 Better workaround for GNOME bug when --enable-gcc-warnings.
4686 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4687 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4688 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4690 Simplify SIGIO usage (Bug#12408).
4691 The code that dealt with SIGIO was crufty and confusing, e.g., it
4692 played tricks like "#undef SIGIO" but these tricks were not used
4693 consistently. Simplify mostly by not #undeffing standard symbols,
4694 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4695 or not as we please) rather than "defined SIGIO" (standard symbol
4696 that we probably shouldn't #undef).
4697 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4698 Modules that need it can include it.
4699 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4700 * dispextern.h (ignore_sigio): New decl.
4701 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4702 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4703 * emacs.c (shut_down_emacs):
4704 * keyboard.c (kbd_buffer_store_event_hold):
4705 Use ignore_sigio rather than invoking 'signal' directly.
4706 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4708 (FIONREAD, SIGIO): Do not #undef.
4709 (tty_read_avail_input): Use #error rather than a syntax error.
4710 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4711 for I_PIPE, used by SETUP_SLAVE_PTY.
4712 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4713 * sysdep.c (croak): Remove; no longer needed. This bit of
4714 temporary code, with Fred N. Fish's comment that it's temporary,
4715 has been in Emacs since at least 1992!
4716 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4717 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4718 * syssignal.h (croak): Remove decl.
4719 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4720 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4721 now that we're termios-only.
4722 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4723 * term.c (dissociate_if_controlling_tty): Use #error rather than
4726 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4727 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4728 to work around GNOME bug 683906.
4729 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4730 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4731 This works around GCC bug 54561.
4733 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4735 More fixes for 'volatile' and setjmp/longjmp.
4736 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4737 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4738 (png_load_body) [HAVE_PNG]:
4739 (jpeg_load_body) [HAVE_JPEG]:
4740 New function, with most of the old parent function's body.
4741 (png_load) [HAVE_PNG]:
4742 (jpeg_load) [HAVE_JPEG]:
4743 Invoke the new function, to avoid longjmp munging our locals.
4744 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4745 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4746 longjmp is passed 2, as the C standard doesn't guarantee this.
4747 Instead, store the failure code into mgr->failure_code.
4749 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4751 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4752 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4753 (syms_of_keyboard): Remove support for unread-command-char.
4755 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4757 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4758 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4759 violation. (Bug#12426)
4761 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4763 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4765 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4767 * eval.c: Add `inhibit-debugger'.
4768 (Qinhibit_debugger): New symbol.
4769 (call_debugger): Bind it instead of Qdebug_on_error.
4770 (maybe_call_debugger): Test Vinhibit_debugger.
4771 (syms_of_eval): Define inhibit-debugger.
4772 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4773 (syms_of_xdisp): Remove inhibit-debug-on-message.
4775 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4777 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4778 If a nonvolatile local variable is written before a _longjmp to
4779 the frame containing the variable, and is read after the _longjmp,
4780 the value read is indeterminate. Some local variables of type
4781 'struct handler' and 'struct catchtag' are used in this way, so
4782 mark each of their slots as volatile if the slot can be set before
4783 _longjmp and read afterwards.
4784 * lisp.h (struct handler): var and chosen_clause are now volatile.
4785 (struct catchtag): val, next, and pdlcount are now volatile.
4787 * bidi.c (bidi_push_it, bidi_pop_it):
4788 * fns.c (copy_hash_table):
4789 * image.c (define_image_type):
4790 * keyboard.c (kbd_buffer_store_event_hold):
4791 * process.c (Fprocess_send_eof):
4792 * xfaces.c (x_create_gc) [HAVE_NS]:
4793 * xgselect.c (xg_select):
4794 Prefer assignment to memcpy when either will do.
4796 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4797 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4798 time an item is removed. No need to mark this function 'inline';
4799 the compiler knows better than we do.
4801 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4803 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4804 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4805 to change_frame_size (Bug#12388).
4806 (windowDidResize:): Pass YES to updateFrameSize.
4808 * nsterm.h: Add delay parameter to updateFrameSize.
4810 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4812 Discard killed buffers from deleted window and frame objects.
4813 This reduces an amount of references to killed buffers and
4814 helps GC to reclaim them faster.
4815 * alloc.c (discard_killed_buffers): New function.
4816 (mark_object): Use it for deleted windows and frames.
4817 (mark_object): If symbol's value is set up for a killed buffer
4818 or deleted frame, restore its global binding.
4819 * data.c (swap_in_global_binding): Add GC notice.
4820 (swap_in_symval_forwarding): Use convenient set_blv_where.
4821 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4822 * window.h: ... to here.
4824 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4826 Convenient macro to check whether the buffer is live.
4827 * buffer.h (BUFFER_LIVE_P): New macro.
4828 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4829 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4831 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4833 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4834 composition cases (Bug#12364).
4836 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4837 overhang of succeeding glyphs overlapping box cursor.
4839 * w32term.c (x_draw_glyph_string): Likewise.
4841 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4843 Simplify, document, and port floating-point (Bug#12381).
4844 The porting part of this patch fixes bugs on non-IEEE platforms
4845 with frexp, ldexp, logb.
4846 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4848 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4849 support, by removing commented-out code and briefly listing the
4850 C89 functions excluded. The commented-out stuff was confusing
4851 maintenance, e.g., we thought we needed cbrt but it was commented out.
4852 (logb): Remove decl; no longer needed.
4853 (isfinite): New macro, if not already supplied.
4854 (isnan): Don't replace any existing macro.
4855 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4856 are present on all C89 platforms.
4857 (Ffrexp): Do not special-case zero, as frexp does the right thing
4859 (Flogb): Do not use logb, as it doesn't have the desired meaning
4860 on hosts that use non-base-2 floating point. Instead, stick with
4861 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4862 frexp, to avoid getting an unspecified result.
4864 * xdisp.c (Qinhibit_debug_on_message): Now static.
4866 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4868 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4869 NSBezierPath (Bug#12131).
4871 2012-09-10 Chong Yidong <cyd@gnu.org>
4873 * fns.c (Fdelq, Fdelete): Doc fix.
4875 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4877 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4878 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4880 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4882 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4883 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4886 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4888 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4889 left fringe if the window has a left margin. This avoids leaving
4890 traces of the cursor because its leftmost pixel is not drawn over.
4892 * dispnew.c (update_window_line): When the left margin area of a
4893 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4894 that screen line. (Bug#12277)
4896 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4898 Assume C89 or later for math functions (Bug#12381).
4899 This simplifies the code, and makes it a bit smaller and faster,
4900 and (most important) makes it easier to clean up signal handling
4901 since we can stop worring about floating-point exceptions in
4902 library code. That was a problem before C89, but the problem
4903 went away many years ago on all practical Emacs targets.
4904 * data.c, image.c, lread.c, print.c:
4905 Don't include <math.h>; no longer needed.
4906 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4907 might be autoconfigured, as that never happens.
4909 * doprnt.c (DBL_MAX_10_EXP):
4910 * print.c (DBL_DIG):
4911 Remove. C89 or later always defines these.
4912 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4913 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4914 (arith_error, domain_error, domain_error2):
4915 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4916 no longer needed -- we simply return what C returns. All uses removed.
4917 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4919 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4920 Remove. All uses expanded, as these macros are no longer used
4921 more than once and are now more trouble than they're worth.
4922 (Ftan): Use tan, not sin / cos.
4923 (Flogb): Assume C89 frexp.
4924 (fmod_float): Assume C89 fmod.
4925 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4926 (init_floatfns): Remove. All uses removed.
4928 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4930 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4931 compositeToPoint for OSX < 10.6 (Bug#12390).
4933 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4935 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4936 This produces more-accurate results.
4938 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4940 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4941 changes (Bug#12088).
4943 2012-09-08 Chong Yidong <cyd@gnu.org>
4945 * syntax.c (Fstring_to_syntax): Doc fix.
4947 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4949 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4950 in the internal border.
4951 (x_set_window_size): Remove static variables and their usage.
4952 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4953 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4954 Remove fringe/internal border adjustment (Bug#11052).
4955 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4956 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4957 (ns_fix_rect_ibw): Remove.
4958 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4959 (ns_dumpglyphs_box_or_relief): Ditto.
4960 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4962 (ns_dumpglyphs_image): Ditto.
4963 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4965 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4966 their usage. Add fringe_extended_p and its use as in other terms.
4967 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4968 scroll bar was removed.
4969 (updateFrameSize): New function.
4970 (windowDidResize): Move code to updateFrameSize and call it.
4972 * nsterm.h (EmacsView): Add updateFrameSize.
4974 2012-09-07 Chong Yidong <cyd@gnu.org>
4976 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4978 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4980 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4982 More signal-handler cleanup (Bug#12327).
4983 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4984 Problem introduced when merging patches. Noted by Eli Zaretskii in
4985 <http://bugs.gnu.org/12327#67>.
4986 * floatfns.c: Comment fix.
4987 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4988 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4989 and anyway the declaration is harmless even if SIGDANGER is not defined.
4990 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4991 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4992 source files not surprisingly expected syssignal.h to define, or
4993 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4994 Include <sys/ioctl.h>, for FIONREAD.
4995 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4996 This eliminates a problem whereby other files mysteriously had
4997 to include "syssignal.h" before including "systty.h" if they
4998 wanted to use "#ifdef SIGIO".
5000 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5002 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5004 * w32.c (sigemptyset): Empty the set.
5005 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5007 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5009 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5011 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5012 (mark_object): Likewise for frame objects.
5014 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5016 * syssignal.h (handle_on_main_thread): Always declare,
5017 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5018 This ports to platforms without HAVE_PTHREAD.
5020 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5022 Signal-handler cleanup (Bug#12327).
5023 Emacs's signal handlers were written in the old 4.2BSD style with
5024 sigblock and sigmask and so forth, and this led to some
5025 inefficiencies and confusion. Rewrite these to use
5026 pthread_sigmask etc. without copying signal sets around. Also,
5027 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5028 'signal', and instead use functions that do not attempt to take
5029 over the system name space. This patch causes Emacs's text
5030 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5031 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5032 Do not include <signal.h> or "syssignal.h", as these
5033 modules do not use signals.
5034 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5035 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5036 Do not include <signal.h>, as "syssignal.h" does that for us now.
5037 * atimer.c (sigmask_atimers): New function.
5038 (block_atimers, unblock_atimers): New functions,
5039 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5041 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5042 no longer needed here.
5043 * emacs.c (main): Inspect existing signal handler with sigaction,
5044 so that there's no need to block and unblock SIGHUP.
5045 * sysdep.c (struct save_signal): New member 'action', replacing
5046 old member 'handler'.
5047 (save_signal_handlers, restore_signal_handlers):
5048 Use sigaction instead of 'signal' to save and restore.
5049 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5050 New function. All users of 'signal' modified to use set_sighandler
5051 if they're writeonly, and to use sys_signal if they're read+write.
5052 (emacs_sigaction_init, forwarded_signal): New functions.
5053 (sys_signal): Remove. All uses replaced by calls to sigaction
5054 and emacs_sigaction_init, or by direct calls to 'signal'.
5055 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5056 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5057 all uses replaced by pthread_sigmask etc. calls.
5058 * syssignal.h: Include <signal.h>.
5059 (emacs_sigaction_init, forwarded_signal): New decls.
5060 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5061 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5062 (sigmask, sys_sigmask): Remove; no longer needed.
5063 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5064 (sigblock, sigunblock, sigfree):
5065 (sigsetmask) [!defined sigsetmask]:
5066 Remove. All uses replaced by pthread_sigmask.
5067 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5068 no longer need to be replaced, and its typical old uses
5069 are now done via emacs_sigaction_init and sigaction.
5070 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5071 (sys_sigdel): Remove; unused.
5072 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5074 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5076 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5077 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5079 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5081 Explicitly mark buffer_defaults and buffer_local_symbols.
5082 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5083 mark_local_symbols here.
5084 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5085 since special buffers aren't marked here any more.
5086 (allocate_buffer): Chain new buffer with all_buffers here...
5087 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5089 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5090 (syms_of_buffer): Remove staticpro of the above.
5091 (init_buffer_once): Set names for buffer_defaults and

5094 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5096 Use bool for booleans in font-related modules.
5097 * font.c (font_intern_prop, font_style_to_value)
5098 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5099 (generate_otf_features, font_check_otf_features, font_check_otf)
5100 (font_match_p, font_list_entities, font_at):
5101 * fontset.c (fontset_id_valid_p, reorder_font_vector
5102 (fontset_find_font, Fset_fontset_font)
5103 (face_suitable_for_char_p) [0]:
5104 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5105 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5106 (m17n_flt_initialized, ftfont_shape_by_flt):
5107 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5108 * nsfont.m (nsfont_draw):
5109 * w32font.c (w32font_draw):
5110 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5111 Use bool for booleans.
5112 * font.h: Adjust to above API changes.
5113 (struct font, struct font_driver, struct font_driver_list):
5114 Use bool for booleans.
5115 (struct font): Remove useless member encoding_type.
5117 * fontset.c, xftfont.c: Omit unnecessary static decls.
5119 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5121 * alloc.c (mark_object): Revert window marking code
5122 since it's unsafe for the Fset_window_configuration.
5124 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5126 Fix race conditions with signal handlers and errno (Bug#12327).
5127 Be more systematic about preserving errno whenever a signal
5128 handler returns, even if it's not in the main thread. Do this by
5129 renaming signal handlers to distinguish between signal delivery
5130 and signal handling. All uses changed.
5131 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5132 * data.c (deliver_arith_signal): Rename from arith_error.
5133 * dispnew.c (deliver_window_change_signal): Rename from
5134 window_change_signal.
5135 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5136 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5137 * keyboard.c (deliver_input_available_signal): Rename from
5138 input_available_signal.
5139 (deliver_user_signal): Rename from handle_user_signal.
5140 (deliver_interrupt_signal): Rename from interrupt_signal.
5141 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5142 (deliver_child_signal): Rename from sigchld_handler.
5143 * atimer.c (handle_alarm_signal):
5144 * data.c (handle_arith_signal):
5145 * dispnew.c (handle_window_change_signal):
5146 * emacs.c (handle_fatal_signal, handle_danger_signal):
5147 * keyboard.c (handle_input_available_signal):
5148 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5149 * process.c (handle_pipe_signal, handle_child_signal):
5150 New functions, with the actual signal-handling code taken from the
5151 original respective signal handlers, sans the sporadic attempts to
5152 preserve errno, since that's now done by handle_on_main_thread.
5153 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5154 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5155 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5157 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5158 Move initialization of main_thread to sysdep.c's init_signals.
5159 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5160 our usage, and simplifies the mainline code.
5161 (record_child_status_change): New static function, as a helper
5162 for handle_child_signal, and with most of the old child handler's
5164 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5165 (handle_child_signal): Use the above.
5166 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5167 Moved here from emacs.c.
5168 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5169 code moved here from emacs.c's main function.
5170 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5171 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5172 This lets callers save and restore errno properly.
5174 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5176 Remove redundant or unused things here and there.
5177 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5178 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5179 * editfns.c (Fcompare_buffer_substrings): Likewise.
5180 * frame.h (struct terminal, struct font_driver_list):
5181 Remove redundant declarations.
5182 * window.h (Qleft, Qright): Likewise.
5184 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5186 Do not mark objects from deleted buffers, windows and frames.
5187 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5188 (mark_object): Likewise for windows and frames.
5190 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5192 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5193 buffer_defaults and buffer_local_symbols as valid objects.
5194 Return special value to denote them.
5196 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5198 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5199 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5200 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5201 (file_name_absolute_p, Fsubstitute_in_file_name):
5202 (check_executable, check_writable, Ffile_accessible_directory_p)
5203 (Fset_file_selinux_context, Fdefault_file_modes)
5204 (Finsert_file_contents, choose_write_coding_system)
5205 (Fwrite_region, build_annotations, a_write, e_write)
5207 * filelock.c (boot_time_initialized, get_boot_time)
5208 (get_boot_time_1, lock_file_1, within_one_second):
5209 * floatfns.c (in_float):
5210 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5211 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5212 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5213 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5214 * window.c (compare_window_configurations):
5215 Use bool for booleans.
5216 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5217 (Fdefault_file_modes): Now mode_t, not int, for modes.
5218 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5219 (internal_delete_file): Now returns void, not a (boolean) int,
5220 since nobody was looking at the return value.
5221 * lisp.h, window.h: Adjust to above API changes.
5223 * xdisp.c (set_message): Simplify and reindent last change.
5225 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5227 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5229 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5231 * eval.c (call_debugger): Make the function non-static so that we
5232 can call it from set_message.
5234 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5235 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5237 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5239 Give more-useful info on a fatal error (Bug#12328).
5240 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5241 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5242 of doing the work ourselves.
5243 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5244 do most of the work.
5245 (fatal_error_backtrace): New function, taken from the guts
5246 of the old fatal_error_signal, but with a new option to output
5248 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5249 info about the signal than just its number.
5250 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5251 * sysdep.c: Include <execinfo.h>
5252 (emacs_backtrace): New function, taken partly from the previous
5253 code of the 'die' function.
5254 (emacs_abort): Call fatal_error_backtrace rather than abort.
5256 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5258 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5259 eager (load-time) macro-expansion.
5260 * lisp.mk (lisp): Add macroexp.
5262 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5264 Simplify redefinition of 'abort' (Bug#12316).
5265 Do not try to redefine the 'abort' function. Instead, redo
5266 the code so that it calls 'emacs_abort' rather than 'abort'.
5267 This removes the need for the NO_ABORT configure-time macro
5268 and makes it easier to change the abort code to do a backtrace.
5269 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
5270 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
5271 Remove; sysdep.c's emacs_abort now takes its place.
5272 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
5273 'abort' changed to use 'emacs_abort'.
5274 * msdos.c (dos_abort) [defined abort]: Remove; not used.
5275 (abort) [!defined abort]: Rename to ...
5276 (emacs_abort): ... new name.
5277 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
5278 the place of the old 'abort' in emacs.c.
5279 * w32.c, w32fns.c (abort): Do not #undef.
5280 * w32.c (emacs_abort): Rename from w32_abort.
5282 2012-09-04 Eli Zaretskii <eliz@gnu.org>
5284 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
5285 offsets[j].dv, since the y axis of the screen coordinates points
5286 down, while the y axis of the font definition coordinates points
5287 up. This fixes display of Arabic diacritics such as KASRA and
5288 KASRATAN. (Bug#11860)
5290 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5292 Be more systematic about _setjmp vs setjmp.
5293 * alloc.c (test_setjmp, mark_stack):
5294 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
5295 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
5296 (png_load, my_error_exit, jpeg_load):
5297 * process.c (send_process_trap, send_process):
5298 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
5299 The underscored versions are up to 30x faster on some hosts.
5300 Formerly, the code used setjmp+longjmp sometimes and
5301 _setjmp+_longjmp at other times, with no particular reason to
5302 prefer setjmp+longjmp.
5304 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
5306 Fix minor problem found by static checking.
5307 * buffer.c (Fdelete_all_overlays): Return nil.
5309 2012-09-03 Martin Rudalics <rudalics@gmx.at>
5311 * buffer.c (Fdelete_all_overlays): New function.
5313 2012-09-03 Chong Yidong <cyd@gnu.org>
5315 * gtkutil.c: Add extern decl for Qxft.
5317 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
5319 * emacs.c, eval.c: Use bool for boolean.
5320 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
5321 (malloc_using_checking) [DOUG_LEA_MALLOC]:
5322 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
5323 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
5324 (main, decode_env_path, Fdaemon_initialized):
5325 * eval.c (call_debugger, Finteractive_p, interactive_p):
5326 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
5327 (maybe_call_debugger, Fbacktrace):
5328 * process.c (read_process_output, exec_sentinel):
5329 Use bool for booleans.
5330 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
5331 All callers changed.
5332 * eval.c (interactive_p): Omit always-true boolean argument
5333 EXCLUDE_SUBRS_P. All callers changed.
5334 * dispextern.h, lisp.h: Reflect above API changes.
5335 * firstfile.c (dummy): Use the address of 'main', whose signature
5336 won't change, instead of the address of 'initialize', whose
5337 signature just changed from int to bool.
5338 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
5339 * msdos.c (fatal_error_in_progress): ... from here.
5340 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
5342 (redisplay_internal, unwind_redisplay): Simply clear
5343 REDISPLAYING_P when unwinding, instead of saving its previous,
5344 always-false value and then restoring it.
5346 Clean up some extern decls.
5347 Mostly, this hoists extern decls out of .c files and into .h files.
5348 That way, we're more likely to catch errors if the interfaces change.
5349 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
5350 declare xg_mark_data.
5351 * dispextern.h (x_frame_parm_handlers):
5353 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
5354 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
5355 (Qultra_bold, Qoblique, Qitalic):
5356 Move extern decl here from .c file.
5357 * alloc.c (xg_mark_data) [USE_GTK]:
5359 * eval.c (Qlexical_binding):
5360 * fns.c (time) [!HAVE_UNISTD_H]:

5366 * process.c (QCfamily, QCfilter):
5367 * widget.c (free_frame_faces):
5368 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
5369 * xfont.c (x_clear_errors):
5370 * xterm.c (x_frame_parm_handlers):
5371 Remove now-redundant extern decls.
5372 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
5373 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
5375 * xfaces.c: Remove unnecessary static decls.
5376 * xterm.c (updating_frame): Remove decl of nonexistent object.
5378 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
5379 when building globals.h, as the objects that are not built on
5380 this host are not needed to compile C files on this host.
5382 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
5384 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
5386 * frame.h: Add missing prototype for x_wm_set_size_hint.
5388 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

5392 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
5393 (Fsubstitute_command_keys):

5398 (make_buffer_string, make_buffer_string_both)
5399 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):
5400 * insdel.c (check_markers, gap_left, adjust_markers_for_insert)

5412 * keyboard.c (decode_timer):
5413 Use bool for boolean.
5414 * intervals.h, lisp.h, systime.h: Reflect above API changes.
5415 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
5417 2012-09-02 Chong Yidong <cyd@gnu.org>
5419 * keymap.c (push_key_description): Print M-TAB as C-M-i
5422 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5424 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
5425 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
5426 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

5430 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
5432 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5434 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5435 more than one grapheme cluster passed to the shaper: compute the
5436 offset adjustment values separately for each cluster. (Bug#11860)
5438 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5439 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5440 about implicit conversions from integer to pointer.
5442 2012-09-01 Daniel Colascione <dancol@dancol.org>
5444 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
5445 system used too early.
5447 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
5449 Better seed support for (random).
5450 * emacs.c (main): Call init_random.
5451 * fns.c (Frandom): Set the seed from a string argument, if given.
5452 Remove long-obsolete Gentzel cruft.
5453 * lisp.h, sysdep.c (seed_random): Now takes address and size, not long.
5454 (init_random): New function.
5456 2012-09-01 Daniel Colascione <dancol@dancol.org>
5458 * xterm.h: Add header guards. Declare x_menubar_window_to_frame.
5459 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
5460 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,
5461 x_wm_set_size_hint, x_query_colors, x_real_positions,
5462 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
5463 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,

5554 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
5555 does not become zero (Bug#12234).

5585 (timeout_handler:): Set timer_fired to YES.
5586 (runDialogAt:): Set timer_fired to NO.
5587 Handle click on close button as quit.
5589 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5590 Add window_closed and button_values. Add void as return value for
5591 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5592 Add process_dialog as new member.
5594 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5596 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

5669 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5671 * window.c (Fset_window_configuration): Revert first part of
5674 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
5676 * nsterm.h (NSPanel): New class variable dialog_return.

5679 Initialize dialog_return.
5680 (windowShouldClose:): Use stop instead of stopModalWithCode.
5681 (clicked:): Ditto, and also set dialog_return (Bug#12258).
5682 (timeout_handler:): Use stop instead of abortModal. Send a dummy

5732 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5733 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5734 not a boolean 'int', since callers never look at the return value.

5737 (emacs_mule_string_char): Remove unused extern decls.
5738 (struct iso_2022_spec, struct coding_system):

5746 Fix spare memory change (Bug#12286).
5747 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5748 (valid_lisp_object_p): Likewise.
5750 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5752 * window.c (Fset_window_configuration): Record any window's old
5753 buffer if it's replaced (see Bug#8789). If the new current
5754 buffer doesn't appear in the selected window, go to its old
5757 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5759 Special MEM_TYPE_SPARE to denote reserved memory.
5760 * alloc.c (enum mem_type): New memory type.
5761 (refill_memory_reserve): Use new type for spare memory.
5762 This prevents live_cons_p and live_string_p from incorrect

5765 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5768 * Makefile.in (.PHONY): versioclean -> versionclean.

5772 * window.c (Qwindow_valid_p, decode_valid_window):
5773 Now static, not extern.
5774 * data.c (Qinterval): Remove; unused.

5791 (map_sub_char_table):
5792 Use bool for boolean.
5793 * character.c (str_to_unibyte): Omit last boolean argument; it was
5794 always 0. All callers changed.
5795 * character.h, charset.h: Adjust to match previous changes.
5796 * character.h (char_printable_p): Remove decl of nonexistent function.
5797 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5798 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5799 are all boolean, so make them single-bit bitfields.
5801 * lisp.h (ASET): Remove attempt to detect side effects.
5802 It was meant to be temporary and it often doesn't work,
5803 because when IDX has side effects the behavior of IDX==IDX
5804 is undefined. See Stefan Monnier in
5805 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5807 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5809 * lisp.h (functionp): New function (extracted from Ffunctionp).
5810 (FUNCTIONP): Use it.
5811 * eval.c (Ffunctionp): Use it.
5813 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5815 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5816 as that's faster and simpler than static storage. Don't bother
5817 with the g_main_context_query overhead if g_main_context_pending
5818 says no events are pending.
5819 (gfds, gfds_size): Remove these static vars.
5820 (xgselect_initialize): Remove; no longer needed.
5821 All uses and decls removed.
5823 * emacs.c (fatal_error_signal_hook): Remove.
5824 All uses removed. This leftover from old code was always 0.
5826 * casefiddle.c, casetab.c, category.c: Use bool for boolean.

5828 * casetab.c (set_case_table):

5839 On assertion failure, print backtrace if available.

5851 Use bool for booleans, instead of int.
5852 * lisp.h, process.h: Adjust prototypes to match above changes.
5853 * callint.c (Fcall_interactively): Don't assume the mark's
5854 offset fits in 'int'.

5866 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5867 Use bool for booleans, instead of int.
5868 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5869 since the 1-or-0 return value is always ignored anyway.
5870 (mmap_initialized_p):
5871 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5872 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5874 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5876 * bidi.c: Use bool for boolean.
5877 This is a bit more readable, and makes the text segment of bidi.o
5878 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5879 Presumably it's faster too.

5913 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5915 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5916 Otherwise, the compiler complains about (A?B:C) where B is void
5917 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5918 (fontset_add): Return void, for FONTSET_ADD.
5920 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>

5924 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5925 (dont_register_blocks) [GC_MALLOC_CHECK]:
5926 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5927 (check_string_bytes, make_specified_string, memory_full)
5928 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5929 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5930 (mark_stack, valid_pointer_p, make_pure_string)
5931 (Fgarbage_collect, survives_gc_p, gc_sweep):
5932 Use bool for booleans, instead of int.
5933 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5934 Remove unused local.
5935 * alloc.c (PURE_POINTER_P):
5936 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5937 * editfns.c (Fformat):
5938 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5940 * fns.c (sweep_weak_table):
5941 * lisp.h (suppress_checking, push_message, survives_gc_p)
5942 (make_pure_string, gc_in_progress, abort_on_gc):
5943 * lread.c (readchar, read1):
5944 * print.c (Fprin1_to_string):
5945 * xdisp.c (push_message):
5946 Use bool for booleans affected directly or indirectly by
5949 Make recently-introduced setters macros.
5950 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5951 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5952 (set_fontset_default, set_fontset_fallback): Rename from their
5953 upper-case counterparts, and make them functions rather than macros.
5954 This is more consistent with the other recently-introduced setters.
5955 These don't need to be inline, since they're local.
5957 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5959 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in

5962 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5964 * lisp.h (vcopy): Use memcpy rather than our own loop.
5965 This fixes a performance regression introduced by the recent
5966 addition of vcopy. This means 'vcopy' will need to be modified
5967 for a copying collector, but that's OK. Also, tighten the
5968 checking in the assertion.
5970 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5972 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5973 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5974 non-base glyph for the width of the base character, according to
5975 what x_draw_composite_glyph_string_foreground expects.
5976 Generate WADJUST value according to composition_gstring_width's
5977 expectations, to produce correct width of the composed character.
5978 Reverse the sign of the DU offset produced by ScriptPlace.
5980 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5982 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.

6003 buffer to the specified position.
6005 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>

6008 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6009 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6010 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6013 2012-08-20 Glenn Morris <rgm@gnu.org>
6015 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6016 Don't assume that `ln -f' works.
6018 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6020 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6021 and later about non-assignments with no effect. See discussion at
6022 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6025 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6027 Inline setter functions for Lisp_Objects slots of struct specbinding.
6028 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6031 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6033 * window.c (select_window): Always make selected window's buffer
6036 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6038 Use AREF and ASET for docstrings of category tables.
6039 * category.h (CATEGORY_DOCSTRING): Use AREF.
6040 (SET_CATEGORY_DOCSTRING): Use ASET.
6041 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6043 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6045 Inline setter functions for hash table members.
6046 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6047 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6048 (set_hash_key_and_value, set_hash_index, set_hash_next)
6049 (set_hash_hash): New functions.
6050 * charset.c, fns.c: Adjust users.
6052 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6054 Inline getter and setter functions for per-buffer values.

6058 * buffer.c, data.c: Adjust users.
6060 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6062 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6064 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6066 Rely on <config.h> + <unistd.h> to declare 'environ',
6067 as gnulib does this if the system doesn't.
6068 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6069 Remove declaration. MS-Windows declares it on stdlib.h which is
6070 included by conf_post.h.
6071 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6072 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6073 * vm-limit.c: Include <unistd.h>, for 'environ'.
6075 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6076 (start_of_data): Remove decl; mem-limits.h provides it.
6078 * xdisp.c (handle_invisible_prop): Make it a bit faster
6079 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6081 2012-08-19 Chong Yidong <cyd@gnu.org>
6083 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6086 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>

6092 (Fkill_local_variable): Likewise.
6094 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6096 * nsfont.m (ns_ascii_average_width): Ensure the string
6097 ascii_printable is initialized with a null-terminated character
6098 array. Otherwise, it can contain undesired extra characters.
6100 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6102 port new setting code to Sun C 5.8 2005/10/13
6103 * chartab.c, lisp.h (char_table_set, char_table_set_range):
6104 Return void, not Lisp_Object. Otherwise, the compiler
6105 complains about (A?B:C) where B is void and C is Lisp_Object
6106 when compiling CHAR_TABLE_SET, due to the recent change to
6107 the API of sub_char_table_set_contents.
6109 2012-08-18 Chong Yidong <cyd@gnu.org>
6111 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE

6282 directly-specified attributes.
6283 (merge_face_ref): Recognize :font.
6285 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

6332 Use C-locale tests instead of locale-specific tests for character
6333 types, since we want the ASCII interpretation here, not the
6334 interpretation suitable for whatever happens to be the current locale.

6939 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6940 * w32.c (init_environment): Change the default values of many
6941 environment variables in dflt_envvars[] to NULL, to avoid pushing
6942 them into environment when they were not already defined.
6943 Remove the code that deletes site-lisp subdirectories from the default
6944 value of EMACSLOADPATH, as it is no longer needed.
6945 (check_windows_init_file): Now external, not static.
6946 Use Vload_path as is, without adding anything, as this function is now
6947 called when Vload_path is already set up.
6949 * w32.h (check_windows_init_file): Add prototype.
6951 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6957 any, in the DEFALT argument into the root of the Emacs build or
6958 installation tree, as appropriate.
6960 * callproc.c (init_callproc_1): Call decode_env_path instead of
6961 doing its equivalent by hand.
6962 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
6963 the code that sets Vexec_path run on MS-Windows.
6965 * lread.c (init_lread): Add comments to #ifdef's.
6967 * msdos.c (dos_set_window_size, IT_update_begin)
6968 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
6969 instead of direct references.

6975 Now constants, not macros.
6977 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
6979 Remove unnecessary casts involving pointers.
6980 These casts are no longer needed now that we assume C89 or later,
6981 since they involve casting to or from void *.

6983 (make_pure_float, make_pure_vector):
6984 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

6993 (x_get_window_property, x_get_window_property_as_lisp_data):
6994 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6995 Remove unnecessary pointer casts.
6996 * alloc.c (record_xmalloc): New function.
6997 * lisp.h (record_xmalloc): New decl.
6998 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6999 more like a function. This is because the pointer cast is not
7000 needed. All uses changed.
7001 * print.c (print_string, print_error_message): Avoid length recalc.
7003 Improve fix for macroexp crash with debugging (Bug#12118).
7004 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7005 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7006 not supposed to be invoked from the garbage collector.
7007 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7008 (gc_aset): New function, which is like ASET but can be
7009 used in the garbage collector.
7010 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

7022 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
7023 (map_w32_filename): Improve commentary. Simplify switch.
7024 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
7025 headers (most versions of MinGW w32api don't).
7026 (get_security_info, create_symbolic_link)
7027 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
7029 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks

7034 have the required privileges.
7035 (get_file_security_desc_by_name): Rename from
7036 get_file_security_desc.

7038 with addition of handling of symlinks and support for 'lstat'.
7039 If possible, get file's attributes and security information by
7040 handle, not by name. Produce S_IFLNK bit for symlinks, when
7041 called from 'lstat'.
7042 (stat, lstat): New functions, call 'stat_worker'.
7043 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7044 symlinks when the underlying filesystem supports them.
7046 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7048 Fix macroexp crash on Windows with debugging (Bug#12118).
7049 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7050 checking subscripts; problem introduced with the recent
7051 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7052 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7053 since it's used in non-static inline functions now.
7055 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7056 Don't assume buffer size fits in 'int'. Remove unused local.

7073 * category.c (CATEGORY_INLINE):
7074 * character.c (CHARACTER_INLINE):
7075 * charset.c (CHARSET_INLINE):
7076 * composite.c (COMPOSITE_INLINE):
7077 * dispnew.c (DISPEXTERN_INLINE):
7078 * sysdep.c (SYSTIME_INLINE):
7079 Define to EXTERN_INLINE, so that the corresponding functions
7080 are compiled into code.
7081 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7082 (INLINE_HEADER_END): New macros.
7083 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

7103 hard-coding the path separator.
7105 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7107 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7108 This how ASET and AREF are supposed to work, and makes
7109 it easier to think about future improvements. See
7110 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7111 * charset.h (set_charset_attr): New function.

7603 the fix for 12036 would have avoided some of the problems noted in

7615 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7616 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7617 not be usable in #if. This simplifies things.
7619 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7621 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7628 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7629 Adjust to changes in lisp.h and emacs.c, by using

7632 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

7634 instead of gdb_valbits.
7635 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7636 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7637 instead of gdb_array_mark_flag.
7638 (xboolvector): Get size from $->size, not $->header.size.
7639 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7640 (xreload, hook-run, hookpost-run): Remove.
7641 * emacs.c: Include <verify.h>.
7642 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7643 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7645 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7646 (gdb_USE_LSB_TAG): New enum constants.
7647 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7648 Also define these as enum constants, so they're visible to GDB.

7650 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these

7655 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7656 more convenient now. All uses changed.
7657 (VALMASK) [USE_LSB_TAG]: Also define in this case.

7660 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

7665 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
7667 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,

8539 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8540 Prefer snprintf to strncpy.
8541 * nsterm.m (ns_term_init):
8542 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8543 * nsterm.m (ns_term_init):
8544 Avoid the need for strncpy, by using build_string or
8545 make_unibyte_string directly. Use dtoastr, not snprintf.
8546 * process.c (Fmake_network_process): Diagnose service names that
8547 are too long, rather than silently truncating them or creating

8565 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8566 where argument type is known to be a Lisp_Cons.

8579 * lisp.h (make_pure_string): Fix prototype.
8580 (build_pure_c_string): New function, defined as static inline. This
8581 provides a better opportunity to optimize away calls to strlen when
8582 the function is called with compile-time constant argument.
8583 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8584 argument, adjust users accordingly. Use build_pure_c_string where
8586 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8587 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8588 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8590 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8592 Avoid calls to strlen in miscellaneous functions.
8593 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8594 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8595 * lread.c (openp): Likewise.
8597 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8599 Avoid calls to strlen in path processing functions.
8600 * fileio.c (file_name_as_directory): Add comment. Change to add
8601 srclen argument and return the length of result. Adjust users
8603 (directory_file_name): Fix comment. Change to add srclen argument,
8604 swap 1st and 2nd arguments to obey the common convention.
8605 Adjust users accordingly.
8606 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8608 2012-07-10 Glenn Morris <rgm@gnu.org>
8610 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
8611 Move PENDING_OUTPUT_COUNT definition to configure.
8613 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
8614 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
8615 * s/gnu.h (DATA_START): Move definitions to configure.
8617 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8618 We include usg5-4-common.h, which defines them both.
8620 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8621 O_RDONLY already includes it).
8623 Stop ns builds setting the EMACSLOADPATH environment variable.
8624 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8625 Now it does not set EMACSLOADPATH, just returns the load-path string.
8626 * nsterm.h: Update accordingly.
8627 * lread.c [HAVE_NS]: Include nsterm.h.
8628 (init_lread) [HAVE_NS]: Use ns_load_path.
8629 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
8631 2012-07-09 Glenn Morris <rgm@gnu.org>
8633 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8634 since the included bsd-common.h does so.
8636 Stop ns builds setting the EMACSPATH environment variable.
8637 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8638 (ns_init_paths): Do not set EMACSPATH.
8639 * nsterm.h (ns_exec_path): Add it.
8640 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8643 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8645 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8647 * process.c (wait_reading_process_output): 'waitchannels' was unset
8648 when read_kbd || !NILP (wait_for_cell); fix this.
8650 Add GCC-style 'const' attribute to functions that can use it.
8651 * character.h (char_resolve_modifier_mask):
8652 * keyboard.h (make_ctrl_char):
8653 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
8654 (init_character_once, next_almost_prime, init_fns, init_image)
8655 (flush_pending_output, init_sound):

8660 Declare the dummy function with ATTRIBUTE_CONST.
8661 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
8662 Add decls with ATTRIBUTE_CONST.
8664 Minor improvements to make_formatted_string.
8665 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8666 where int is good enough, as vsprintf returns an int.
8667 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8669 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8671 Use make_formatted_string to avoid double length calculation.
8672 * lisp.h (make_formatted_string): New prototype.
8673 * alloc.c (make_formatted_string): New function.
8674 * buffer.c (Fgenerate_new_buffer_name): Use it.
8675 * dbusbind.c (syms_of_dbusbind): Likewise.
8676 * editfns.c (Fcurrent_time_zone): Likewise.
8677 * filelock.c (get_boot_time): Likewise.
8678 * frame.c (make_terminal_frame, set_term_frame_name)
8679 (x_report_frame_params): Likewise.
8680 * image.c (gs_load): Likewise.
8681 * minibuf.c (get_minibuffer): Likewise.

8694 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
8696 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8698 Move marker debugging code under MARKER_DEBUG.
8699 * marker.c (MARKER_DEBUG): Move marker debugging code under
8700 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8701 for bootstrap with --enable-checking (~3x slowdown reported
8702 by Juanma Barranquero <lekktu@gmail.com>).
8703 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8705 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8707 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8708 See <http://bugs.gnu.org/11825#29>.
8710 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8712 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8713 has no font, use the frame's font. (Bug#11813)
8714 (display_line): Add commentary about displaying truncation glyphs
8716 (produce_special_glyphs): Move here from term.c.
8718 * term.c (produce_special_glyphs): Move to xdisp.c.
8720 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8723 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8725 * xdisp.c (display_line): Avoid warning about implicit declaration
8728 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8730 * lisp.h: Remove empty conditional.
8732 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8734 * lread.c (load_path_check): Now static.
8736 Fix some minor --with-ns problems found by static checking.
8737 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8738 (x_set_font) [!HAVE_X_WINDOWS]:
8739 * image.c (xpm_load_image) [HAVE_NS]:
8740 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8741 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8742 Remove unused local.
8743 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8744 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8745 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8746 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8747 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8748 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8749 Fix pointer signedness problem.
8750 * xfaces.c (FRAME_X_FONT_TABLE):
8751 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8753 2012-07-07 Glenn Morris <rgm@gnu.org>
8755 * lread.c (load_path_check): New function, split from init_lread.
8756 (init_lread): Reorganize. Motivation:
8757 If EMACSLOADPATH is set, check/warn about that rather than the
8758 defaults, which we are not going to use. Hence we can remove
8759 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8760 Don't warn if site-lisp directories are missing.
8761 If not installed, start from a blank load-path, since
8762 PATH_LOADSEARCH refers to the eventual installation directories.
8764 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8766 Support truncation and continuation glyphs on GUI frames, when
8767 fringes are disabled. (Bug#11832)
8768 * xdisp.c (init_iterator): Get dimensions of truncation and
8769 continuation glyphs even if on GUI frames.
8770 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8771 or both, are absent.
8772 (start_display, move_it_in_display_line_to): Handle the case of a
8773 GUI frame without a fringe to display continuation or truncation
8775 (insert_left_trunc_glyphs): Support GUI frames: make sure
8776 truncation glyphs overwrite enough glyphs from the current line to
8777 have sufficient space in pixels.
8778 (display_line): Support truncation and continuation glyphs on GUI
8779 frames. If some spare pixels are left on the line after inserting
8780 the truncation glyphs, fill that space with a stretch glyph of a
8781 suitably computed width.
8783 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8784 produce_glyphs, to support GUI sessions.
8786 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8788 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8790 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8792 Do not require float-time's arg to fit in time_t (Bug#11825).
8793 This works better on hosts where time_t is unsigned, and where
8794 float-time is applied to the (negative) difference between two times.
8795 * editfns.c (decode_time_components): Last arg is now double *,
8796 not int *, and means to store all the result as a double, without
8797 worrying about whether the seconds part fits in time_t.
8798 All callers changed.
8799 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8800 All callers changed.
8801 (Ffloat_time): Do not fail merely because the specified time falls
8802 outside of time_t range.
8804 2012-07-07 Glenn Morris <rgm@gnu.org>
8806 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8812 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8813 Update dependencies.
8815 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8817 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8819 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

8821 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8822 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8823 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
8824 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
8826 * xfont.c (compare_font_names): Redo to omit the need for casts.
8828 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8830 * xfns.c (Fx_change_window_property): Doc fix.
8831 * w32fns.c (Fx_change_window_property): Doc fix.
8833 * w32fns.c (Fx_window_property): Accept the same arguments as the
8834 X Windows version. Doc fix.
8835 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8837 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8838 Eli Zaretskii <eliz@gnu.org>
8840 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8841 Windows-specific code from nt/config.nt moved here.
8842 Obsolete settings removed.
8844 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8846 * process.c: Avoid unnecessary calls to gettime.
8847 (wait_reading_process_output): Don't get the time of day
8848 when gobbling data immediately and not waiting, as there's no need
8849 for it in that case. This removes a FIXME.
8851 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8853 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8854 is defined (Bug#11768).
8856 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8858 Fix marker debugging code.
8859 * marker.c (byte_char_debug_check): Do not perform the check
8860 if buffer is not multibyte.
8861 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8862 Call byte_char_debug_check with correct arguments.
8864 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8866 Compile marker debugging code only if ENABLE_CHECKING is defined.
8867 * marker.c (byte_char_debug_check, count_markers):
8868 Use only if ENABLE_CHECKING is defined.
8869 (byte_debug_flag): Remove.
8870 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8871 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8873 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8875 Avoid code repetition in marker-related functions.
8876 * marker.c (attach_marker): New function.
8877 (Fset_marker, set_marker_restricted, set_marker_both)
8878 (set_marker_restricted_both): Use it.
8879 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8880 Consistently rename charno to charpos.
8881 (marker_position): Add eassert.
8882 (marker_byte_position): Convert to eassert.

8901 * window.c (save_window_save): Likewise.
8903 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8905 Do not use Fdelete_overlay in delete_all_overlays
8906 to avoid redundant calls to unchain_overlay.
8907 * buffer.c (drop_overlay): New function.
8908 (delete_all_overlays, Fdelete_overlay): Use it.
8909 * minibuf.c (get_minibuffer): Fix comment.
8911 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8913 Port to OpenBSD 5.1 amd64.
8914 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8915 This is needed for OpenBSD, and should be harmless on all BSD systems.
8916 Also, include <sys/sysctl.h>, as it should be available on all
8917 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8918 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8919 use p_pid member, not kp_proc.pid.
8921 2012-07-06 Glenn Morris <rgm@gnu.org>
8923 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8925 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8927 More xmalloc and related cleanup.

8936 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8938 Omit needless casts involving void * pointers and allocation.
8939 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8940 as the former is more robust if P's type is changed.
8941 Prefer xzalloc to xmalloc + memset 0.
8942 Simplify malloc-or-realloc to realloc.
8943 Don't worry about xmalloc returning a null pointer.
8944 Prefer xstrdup to xmalloc + strcpy.
8945 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8947 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8948 alloca of a constant.
8950 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8952 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8953 hscroll is larger than the line width. Fixes long and futile
8954 looping inside extend_face_to_end_of_line (on a TTY) producing
8955 glyphs that are not needed and thrown away.
8957 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

8985 * xdisp.c (window_hscroll_limited): New function.
8986 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8987 coordinates when window's hscroll is set to insanely large
8990 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8992 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

9053 * fileio.c (time_error_value): Check the right error number.
9054 Problem reported by Troels Nielsen in
9055 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9057 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9059 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9060 This should be fixed in a better way; see Eli Zaretskii in
9061 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9062 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9064 * fileio.c (time_error_value): Rename from special_mtime.
9065 The old name's problems were noted by Eli Zaretskii in
9066 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9068 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9069 This variable's comment says Emacs needs at least one GDB-visible
9070 symbol of type enum pvec_type, to work around GDB problems.
9071 The symbol's value doesn't matter.
9073 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9074 that causes compilation to fail on pre-C99 compilers.
9076 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9078 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

9081 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9083 * buffer.c (init_buffer_once): Fix initialization of
9084 headers for buffer_defaults and buffer_local_symbols.
9085 Reported by Juanma Barranquero <lekktu@gmail.com>.
9087 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9089 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9090 * lisp.h (enum pvec_type): Use fewer bits.
9091 (PSEUDOVECTOR_SIZE_BITS): New constant.
9092 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9093 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9094 change in pvec_type.
9095 (PSEUDOVECTOR_TYPEP): New macro.
9096 (TYPED_PSEUDOVECTORP): Use it.
9097 * fns.c (internal_equal): Adapt code to extract pvectype.

9101 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9102 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9103 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9104 abusing vector->header.next.nbytes.
9105 (live_vector_p): Use PVEC_TYPE.
9106 (mark_object): Adapt code to extract pvectype. Use switch.
9108 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9110 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9111 Tighten new eassert a bit.
9113 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9115 Fix compilation with --enable-gcc-warnings and -O1
9117 * doprnt.c (doprnt): Change type of tem to int, initialize
9118 to avoid compiler warning. Add eassert.
9119 * search.c (simple_search): Initialize match_byte to avoid
9120 compiler warning. Add eassert.
9122 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9124 Avoid weird behavior with large horizontal scrolls.
9125 Without this change, for example, large hscroll values would
9126 mess up Emacs's display on Fedora 15 x86, presumably due to
9127 overflows in int calculations in the display code.
9128 Also, if buffers had long lines, Emacs would freeze.
9129 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9130 (set_window_hscroll): New function, containing the old guts of
9131 Fset_window_hscroll. Return the clipped value.
9132 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9133 This avoids the need to check against PTRDIFF_MAX.
9135 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9137 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9139 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9141 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9143 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9144 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9145 since GCC 4.4.6 issues a bogus warning for them.
9147 Fix bugs in file timestamp newness comparisons.
9148 * fileio.c (Ffile_newer_than_file_p):
9149 * lread.c (Fload): Use full timestamp resolution of files,
9150 not just the 1-second resolution, so that files that are only
9151 slightly newer still count as newer.
9152 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9153 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9155 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9157 * fileio.c: Improve handling of file time marker. (Bug#11852)
9158 (special_mtime): New function.
9159 (Finsert_file_contents, Fverify_visited_file_modtime):
9160 Use it to set special mtime values consistently.
9162 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9164 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9165 marker for non-existing file. (Bug#11852)
9167 2012-07-03 Glenn Morris <rgm@gnu.org>
9169 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9170 and did not make it into globals.h).
9172 2012-07-03 Tom Tromey <tromey@redhat.com>
9174 * window.c (Fset_window_margins, Fset_window_fringes)

9210 2012-07-03 Glenn Morris <rgm@gnu.org>
9212 * lisp.h (Frandom): Make it visible to C.
9213 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9214 buffer for invisible buffers. (Bug#1229)
9216 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9218 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9219 values which aren't power of 2.
9220 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9221 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9224 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9226 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9228 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9230 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9232 * alloc.c (allocate_vector_block): Remove redundant
9233 calls to mallopt if DOUG_LEA_MALLOC is defined.
9234 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9235 avoid calls to mallopt if zero_vector is returned.
9237 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9239 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9240 is enabled, avoid dereferencing NULL current_sblock if
9243 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9245 Cleanup basic buffer management.
9246 * buffer.h (struct buffer): Change layout to use generic vector
9247 marking code. Fix some comments. Change type of 'clip_changed'
9248 to bitfield. Remove unused #ifndef old.
9249 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9250 (GET_OVERLAYS_AT): Fix indentation.
9251 (for_each_per_buffer_object_at): New macro.
9252 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

9254 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
9255 * alloc.c (allocate_buffer): Adjust to match new layout of
9256 struct buffer. Fix comment.
9257 (mark_overlay): New function.
9258 (mark_buffer): Use it. Use mark_vectorlike to mark normal
9259 Lisp area of struct buffer.
9260 (mark_object): Use it. Adjust marking of misc objects
9261 and related comments.
9263 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
9265 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
9266 wrapper that is not needed because the wrapped code is a no-op (zero
9267 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
9268 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
9270 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
9272 * alloc.c (mark_buffer): Simplify. Remove prototype.
9273 (mark_object): Add comment. Reorganize marking of vector-like
9274 objects. Use CHECK_LIVE for all vector-like objects except buffers
9275 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
9276 Avoid redundant calls to mark_vectorlike for bool vectors.
9278 2012-06-30 Glenn Morris <rgm@gnu.org>
9280 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
9282 * epaths.in (PATH_SITELOADSEARCH): New.
9283 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
9284 This is rather than relying on --enable-locallisppath elements
9285 having "site-lisp" in their names. (Bug#10208#25, 11658)
9287 2012-06-30 Eli Zaretskii <eliz@gnu.org>
9289 * w32proc.c (sys_select): Accept and ignore one more argument.
9291 * w32.c (emacs_gnutls_pull): Call select with one more argument.
9293 * sysselect.h [DOS_NT]: Don't include sys/select.h.
9294 (pselect) [!MS_DOS]: Redirect to sys_select.
9296 * sysdep.c: Don't include dos.h and dosfns.h.
9298 * process.c (sys_select):
9299 * msdos.c (sys_select): Accept one more argument and ignore it.
9301 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
9302 adapt data types and code to that.
9305 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
9306 which clashes with the gnulib function of the same name.
9308 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
9310 * font.c (font_style_to_value, font_style_symbolic)
9311 (font_prop_validate_style): Add type checks for values in
9314 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
9316 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
9319 2012-06-29 Eli Zaretskii <eliz@gnu.org>
9321 * xdisp.c (try_window_id): Undo last change.
9323 * w32.c (getwd): Adjust commentary about startup_dir.
9324 (init_environment): Always call sys_access, even in non-MSVC
9325 builds. Don't chdir to the directory of the Emacs executable.
9326 This undoes code from 1997 which was justified by the need to
9327 "avoid conflicts when removing and renaming directories". But its
9328 downside was that every relative file name was being interpreted
9329 relative to the directory of the Emacs executable, which can never
9330 be TRT. In particular, it broke sys_access when called with
9331 relative file names.
9332 (sys_access): Map GetLastError to errno.
9334 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9336 * window.h (struct window): Change type of 'fringes_outside_margins'
9337 to bitfield. Fix comment. Adjust users accordingly.
9338 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
9340 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
9343 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
9345 * gnutls.c (emacs_gnutls_handshake):
9346 Add QUIT to make the loop interruptible.
9348 2012-06-29 Glenn Morris <rgm@gnu.org>
9350 * charset.c (init_charset): Make lack of etc/charsets fatal.
9352 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
9354 * editfns.c (region_limit): Fix type mismatch.
9356 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

9359 undefined. Convert from xassert to eassert.
9360 * nsmenu.m: Convert from xassert to eassert.
9361 * nsterm.m: Likewise.
9363 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
9365 * editfns.c (region_limit): Clip to narrowing (bug#11770).
9367 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
9369 Avoid integer overflow on scroll-left and scroll-right.
9370 * window.c (HSCROLL_MAX): New macro.
9371 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
9372 overflow when requested scroll falls outside ptrdiff_t range.
9374 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
9376 * window.h (struct window): Change type of 'hscroll',
9377 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
9378 'last_modified' and 'last_overlay_modified' to EMACS_INT.
9379 Adjust users accordingly.
9380 * xdisp.c (try_cursor_movement): Replace type check with eassert.
9381 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
9382 from EMACS_INT to ptrdiff_t.
9383 (make_window): Omit redundant initialization.
9385 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

9389 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

9458 * alloc.c (allocate_string): Omit intervals initialization.
9459 * alloc.c (make_uninit_multibyte_string): Initialize intervals

9516 * alloc.c: Remove build_string.
9517 * lisp.h: Define build_string as static inline. This provides
9518 a better opportunity to optimize away calls to strlen when the
9519 function is called with compile-time constant argument.
9520 * image.c (imagemagick_error): Convert to build_string.
9521 * w32proc.c (sys_spawnve): Likewise.

9524 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9526 Use sprintf return value instead of invoking strlen on result.
9527 In the old days this wasn't portable, since some sprintf
9528 implementations returned char *. But they died out years ago and
9529 Emacs already assumes sprintf returns int.
9530 Similarly for float_to_string.
9531 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

9538 * xfns.c (syms_of_xfns):
9539 Use sprintf or float_to_string result to avoid need to call strlen.
9540 * data.c (Fnumber_to_string):
9541 Use make_unibyte_string, since the string must be ASCII.
9542 * lisp.h, print.c (float_to_string): Now returns int length.
9543 * term.c (produce_glyphless_glyph):
9544 Use sprintf result rather than recomputing it.
9546 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9547 * Makefile.in (ALL_CFLAGS):

9645 * keyboard.c (kbd_buffer_get_event):
9646 * process.c (Faccept_process_output):
9647 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9648 This improves on the previous patch, which introduced a bug
9649 when time_t is unsigned and as wide as intmax_t.
9650 See <http://bugs.gnu.org/9000#51>.

9681 language ID in the event parameters.
9683 * w32term.c (w32_read_socket): Put the new keyboard codepage into

9713 Don't assume EMACS_TIME and struct timeval are the same type.
9715 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9717 Support higher-resolution time stamps (Bug#9000).
9718 The time stamps are only nanosecond-resolution at the C level,
9719 since that's the best that any real-world system supports now.
9720 But they are picosecond-resolution at the Lisp level, as that's
9721 easy, and leaves room for future OS improvements.
9723 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9726 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9727 Don't get current time unless it's needed.
9729 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9730 now provides it if it's absent.
9731 (start_atimer): Port to higher-res time stamps.
9732 Check for time stamp overflow. Don't get current time more
9733 often than is needed.
9735 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9736 Include systime.h, not time.h.
9737 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9739 * dired.c: Include stat-time.h.
9740 (Ffile-attributes): File times now have higher resolution.

9743 (struct image): Timestamp now has higher resolution.
9745 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9746 has at least microseconds now. All uses removed.
9747 (update_frame, update_single_window, update_window, update_frame_1)
9748 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9749 (duration_to_sec_usec): Remove; no longer needed.
9751 * editfns.c (time_overflow): Now extern.

9757 (decode_time_components, lisp_seconds_argument): New functions.
9758 (make_time): Now static.
9759 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9760 Report an error if the time is invalid, rather than having the caller
9763 * fileio.c: Include <stat-time.h>
9764 (Fcopy_file): Copy higher-resolution time stamps.
9765 Prefer to set the time stamp via a file descriptor if that works.

9767 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9768 (Fvisited_file_modtime, Fset_visited_file_modtime):
9769 Support higher-resolution time stamps.
9771 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9773 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9775 * image.c (prepare_image_for_display, clear_image_cache)
9776 (lookup_image): Port to higer-resolution time stamps.
9778 * keyboard.c (start_polling, bind_polling_period):
9779 Check for time stamp overflow.
9780 (read_char, kbd_buffer_get_event, timer_start_idle)
9781 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9782 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9783 Port to higher-resolution time stamps. Do not assume time_t is signed.
9784 (decode_timer): New function. Timers are now vectors of length 9,
9785 not 8, to accommodate the picosecond component.
9786 (timer_check_2): Use it.
9788 * nsterm.m (select_timeout, timeval_subtract): Remove.
9789 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9790 as they're a bit more accurate and handle overflow better.
9791 (ns_select): Change prototype to be compatible with pselect.
9792 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9793 * nsterm.h (ns_select): Adjust prototype.
9795 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9796 us-resolution time stamps.
9797 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9799 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9801 * lisp.h (time_overflow): New decl.
9802 (wait_reading_process_output): First arg is now intmax_t, not int,
9803 to accommodate larger waits.
9805 * process.h (struct Lisp_Process.read_output_delay):
9806 Now counts nanoseconds, not microseconds.
9807 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9809 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9810 (wait_reading_process_output):
9811 Port to ns-resolution time stamps.
9812 (Faccept_process_output, wait_reading_process_output):
9813 Check for time stamp overflow. Do not assume time_t is signed.
9814 (select_wrapper): Remove; we now use pselect.
9815 (Fprocess_attributes): Now generates ns-resolution time stamps.
9817 * sysdep.c: Include utimens.h. Don't include utime.h
9818 or worry about struct utimbuf; gnulib does that for us now.
9819 (gettimeofday): Remove; gnulib provides a substitute.
9820 (make_timeval): New function.
9821 (set_file_times): Now sets ns-resolution time stamps.
9822 New arg FD; all uses changed.
9823 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9824 (system_process_attributes):
9825 Now returns ns-resolution time stamp. All uses changed.
9826 Check for time stamp overflow.
9828 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9829 provides a substitute now.
9831 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9832 since it guarantees struct timespec.
9833 (EMACS_TIME): Now struct timespec, so that we can support
9834 ns-resolution time stamps.
9835 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9836 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9837 (EMACS_USECS): Remove.
9838 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9839 so multiply the arg by 1000 before storing it.
9840 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9842 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9843 Port to ns-resolution time stamps.
9844 (EMACS_TIME_NEG_P): Remove; replaced by....
9845 (EMACS_TIME_SIGN): New macro.
9846 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9847 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
9848 (set_file_times, make_time, lisp_time_argument): Adjust signature.
9849 (make_timeval, make_lisp_time, decode_time_components): New decls.
9850 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9851 that it mishandled time_t overflow. You can't compare by subtracting!
9852 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9853 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9855 * term.c: Include <sys/time.h>.
9856 (timeval_to_Time): New function, for proper overflow wraparound.

9864 (w32_get_internal_run_time):
9865 Port to higher-resolution Emacs time stamps.
9866 (ltime): Now accepts single 64-bit integer, as that's more convenient
9869 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9871 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9872 for compatibility with pselect. Support ns-resolution time stamps.
9874 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9876 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9877 Check for time stamp overflow, and support ns-resolution time stamps.
9879 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9880 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9881 (timeval_subtract): Remove; no longer needed.
9882 (XTflash, XTring_bell, x_wait_for_event):
9883 Port to ns-resolution time stamps. Don't assume time_t is signed.
9885 2012-06-22 Chong Yidong <cyd@gnu.org>
9887 * xdisp.c (x_consider_frame_title): Revert last change.
9889 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9891 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9892 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9893 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9894 staticidx goes up to 1597 out of 1600 = 0x640.)
9896 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9898 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9899 Otherwise, the umask might be mistakenly 0 while handling input signals.

9909 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
9910 access to `contents' member of Lisp_Vector objects with AREF and ASET
9913 2012-06-19 Chong Yidong <cyd@gnu.org>
9915 * frame.c (delete_frame): When selecting a frame on a different
9916 text terminal, do not alter the terminal's top-frame.

9920 (unwind_format_mode_line): Restore them.
9921 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9923 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9924 since tty frames can be explicitly named.
9925 (prepare_menu_bars): Likewise.
9927 * term.c (Ftty_top_frame): New function.
9929 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9931 Port byte-code-meter to modern targets.
9932 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9933 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9934 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9935 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
9936 (METER_1, METER_2): Simplify.
9938 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
9940 * data.c (Fdefalias): Return `symbol' (bug#11686).
9942 2012-06-18 Martin Rudalics <rudalics@gmx.at>
9944 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9945 gets killed during executing of this function (Bug#11665).
9946 Try to always return Qt when the buffer has been actually killed.
9947 (Vkill_buffer_query_functions): In doc-string say that functions
9948 run by this hook should not change the current buffer.
9950 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9952 Fix recently-introduced process.c problems found by static checking.
9953 * process.c (write_queue_push, write_queue_pop, send_process):

9956 (send_process): Remove unused local.
9958 2012-06-17 Chong Yidong <cyd@gnu.org>

9961 frames that are not on top.
9963 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
9965 * process.c (make_process): Initialize write_queue.
9966 (write_queue_push, write_queue_pop): New functions.

9970 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
9972 * lisp.h (eassert): Assume C89 or later.
9973 This removes the need for CHECK.
9974 (CHECK): Remove. Its comments about always evaluating its
9975 argument were confusing, as 'eassert' typically does not evaluate
9978 * coding.c (produce_chars): Use ptrdiff_t, not int.
9980 * xterm.c (x_draw_underwave): Check for integer overflow.
9981 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
9983 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
9985 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

10169 Use an inline function on all platforms when using the union type,

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

10371 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
10372 Convert pctcpu and pctmem to Lisp float properly.
10373 Let the compiler fold better, as 100.0/0x8000 is exact.

10377 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

10389 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
10390 change its type from Lisp_Object to bitfield.

10399 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
10400 Use 'float' consistently, rather than 'float' in most places
10401 and 'double' in a couple of places.
10403 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10405 * xdisp.c (handle_stop): Detect whether we have overlay strings
10406 loaded by testing it->current.overlay_string_index to be
10407 non-negative, instead of checking whether n_overlay_strings is
10408 positive. (Bug#11587)

10425 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10426 for the duration of call to load_charset, to avoid problems with

10431 decrement the inhibition flag, instead of just setting or

10437 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

10451 * emacs.c: Include <sys/gmon.h> when profiling.
10452 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10453 (__executable_start): Remove decl, since lisp.h does it now.
10454 (safe_bcopy): Remove decl; no longer has that name.
10455 (main): Coalesce #if into single bit of code, for simplicity.
10456 Cast pointers to uintptr_t, since standard libraries want integers
10458 * lisp.h (__executable_start): New decl.
10460 2012-05-31 Glenn Morris <rgm@gnu.org>
10462 * image.c (Fimagemagick_types): Doc fix.

10483 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10485 Do not create empty overlays with the evaporate property (Bug#9642).
10486 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10487 Bug#9642, but explicitly check that the buffer the overlay would
10488 be moved to is live and rearrange lines to make sure that errors
10489 will not put the overlay in an inconsistent state.
10490 (Fdelete_overlay): Cosmetics.
10492 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10494 * w32term.c (my_bring_window_to_top): New function.
10495 (x_raise_frame): Use handle returned by DeferWindowPos, which
10496 could be different from the original one.

10506 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10508 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10509 This avoids undefined behavior that might cause the eassert
10510 to not catch an out-of-range value.
10512 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10514 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10515 Update dependencies.
10517 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10519 * bidi.c (bidi_mirror_char): Fix last change.
10521 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

10524 when referring to sectname field in printf format.
10526 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10528 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10529 Only r_alloc_inhibit_buffer_relocation needed to be added;
10530 the others were already declared.
10532 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10533 before checking whether it's out of range. Put the check inside
10535 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10537 2012-05-27 Ken Brown <kbrown@cornell.edu>
10539 * callproc.c (Fcall_process): Restore a line that was accidentally
10540 commented out in the 2011-02-13 change (bug#11547).
10542 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10544 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10545 defined on ralloc.c.
10547 * buffer.c [REL_ALLOC]: Remove prototypes of
10548 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10549 they are now on lisp.h.
10551 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10553 * search.c (search_buffer): Use it to inhibit relocation of buffer
10554 text while re_search_2 is doing its job, because re_search_2 is
10555 passed C pointers to buffer text. (Bug#11519)
10557 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10558 Update value to 24.
10560 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10561 state after an additional call to move_it_in_display_line_to, keep
10562 the values of it->max_ascent and it->max_descent found for the
10564 (pos_visible_p): Revert the comparison against bottom_y to what it
10565 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10568 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10570 Fix coding-related core dumps with gcc -ftrapv.
10571 The code was computing A - B, where A and B are pointers, and B is
10572 random garbage. This can lead to core dumps on platforms that
10573 have special pointer registers, and it also leads to core dumps on
10574 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10575 A - B only when B is initialized properly.
10576 * coding.c (coding_set_source, coding_set_destination): Return void.
10577 (coding_change_source, coding_change_destinations): New functions,
10578 with the old behaviors of coding_set_source and coding_set_destination.
10579 All callers that need an offset changed to use these new functions.
10581 2012-05-26 Glenn Morris <rgm@gnu.org>
10583 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
10585 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10587 Extend mouse support on W32 text-mode console.
10588 * xdisp.c (draw_row_with_mouse_face):
10589 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10591 * w32console.c: Include window.h.
10592 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10594 (initialize_w32_display): Initialize mouse-highlight data.
10596 * w32inevt.c: Include termchar.h and window.h.
10597 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10598 moves, call note_mouse_highlight. If help_echo changed, call
10599 gen_help_event to produce help-echo message in the echo area.
10600 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10603 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10605 * lread.c (read1): Simplify slightly to avoid an overflow warning
10606 with GCC 4.7.0 on x86-64.
10608 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10610 * bidi.c (bidi_mirror_char): Revert last change: an int is
10611 definitely wide enough here.
10613 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10615 Fix integer width and related bugs (Bug#9874).

10617 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
10618 (string_bytes, check_sblock, allocate_string_data):
10619 (compact_small_strings, Fmake_bool_vector, make_string)

10622 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10623 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10625 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10626 (allocate_pseudovector):
10627 Use int, not EMACS_INT, where int is wide enough.
10628 (inhibit_garbage_collection, Fgarbage_collect):
10629 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10630 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10631 int might not be wide enough.
10632 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10633 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10634 (bidi_at_paragraph_end, bidi_find_paragraph_start)
10635 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
10636 (bidi_level_of_next_char, bidi_move_to_visually_next):

10638 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
10639 (Fkill_buffer, Fset_buffer_major_mode)
10640 (advance_to_char_boundary, Fbuffer_swap_text)

10647 (Foverlay_recenter, last_overlay_modification_hooks_used)
10648 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10649 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10650 (validate_region): Omit unnecessary test for b <= e,
10651 since that's guaranteed by the previous test.
10652 (adjust_overlays_for_delete): Avoid pos + length overflow.
10653 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10654 (report_overlay_modification):
10655 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10656 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10657 Omit pointer cast, which isn't needed anyway, and doesn't work
10658 after the EMACS_INT -> ptrdiff_t change.
10659 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10660 * buffer.h: Adjust decls to match defn changes elsewhere.
10661 (struct buffer_text, struct buffer):
10662 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10663 Use EMACS_INT, not int, where int might not be wide enough.
10664 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10665 not int, to avoid needless 32-bit limit on 64-bit hosts.
10666 (exec_byte_code): Use tighter memory-full test, one that checks
10667 for alloca overflow. Don't compute the address of the object just
10668 before an array, as that's not portable. Use EMACS_INT, not
10669 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10670 * callint.c (Fcall_interactively):
10671 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10672 * callproc.c (call_process_kill, Fcall_process):
10673 Don't assume pid_t fits into an Emacs fixnum.
10674 (call_process_cleanup, Fcall_process, child_setup):

10678 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10679 (Fcall_process): Simplify handling of volatile integers.

10682 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10683 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10684 (casify_object): Avoid integer overflow when overallocating buffer.
10685 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10686 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10687 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10688 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10689 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10690 integers are now checked earlier. All uses replaced with XINT.
10692 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10693 For CCL_MapSingle, check that content and value are in int range.
10694 (ccl_driver, Fregister_code_conversion_map):
10695 Check that Vcode_version_map_vector is a vector.
10696 (resolve_symbol_ccl_program): Check that vector header is in range.
10697 Always copy the vector, so that we can check its contents reliably
10698 now rather than having to recheck each instruction as it's being
10699 executed. Check that vector words fit in 'int'.
10700 (ccl_get_compiled_code, Fregister_ccl_program)
10701 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10702 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10703 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10704 contents are in range.
10705 (Fccl_execute_on_string): Check that status is in range.
10706 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10707 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10708 Accept and return EMACS_INT, not int, because callers can pass values
10709 out of 'int' range.
10710 (c_string_width, strwidth, lisp_string_width, chars_in_text)
10711 (multibyte_chars_in_text, parse_str_as_multibyte)

10714 (string_escape_byte8, Fget_byte):
10715 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10716 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10717 avoid mishandling large integers.
10718 * character.h: Adjust decls to match defn changes elsewhere.
10719 * charset.c (load_charset_map_from_file, find_charsets_in_text)

10724 Don't assume fixnum fits in int.
10725 (load_charset_map_from_vector, Fmap_charset_chars):
10726 Remove now-unnecessary CHECK_NATNUMs.
10727 (Fdefine_charset_internal): Check ranges here, more carefully.
10728 Don't rely on undefined behavior with signed left shift overflow.
10729 Don't assume unsigned int fits into fixnum, or that fixnum fits
10730 into unsigned int. Don't require max_code to be a valid fixnum;
10731 that's not true for gb10830 4-byte on a 32-bit host. Allow
10732 invalid_code to be a cons, for the same reason. Require code_offset
10733 to be a character. Avoid int overflow if max_char is close
10735 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10736 this is intended anyway and avoids some undefined behavior.
10737 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10738 INDEX_TO_CODE_POINT, as that's what it expects.
10739 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10740 * charset.h (DECODE_CHAR): Return int, not unsigned;
10741 this is what was intended anyway, and it avoids undefined behavior.
10742 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10743 integer-overflow issues.
10744 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10745 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10746 where the argument is EMACS_INT, and this behavior is not intended.
10747 * chartab.c (Fmake_char_table, Fset_char_table_range)
10748 (uniprop_get_decoder, uniprop_get_encoder):
10749 Don't assume fixnum fits in int.
10750 * cmds.c (move_point): New function, that does the gist of
10751 Fforward_char and Fbackward_char, but does so while checking
10752 for integer overflow more accurately.
10753 (Fforward_char, Fbackward_char): Use it.
10754 (Fforward_line, Fend_of_line, internal_self_insert)
10755 (internal_self_insert):
10756 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10757 Fix a FIXME, by checking for integer overflow when calculating

10791 (consume_chars): Rewrite to not calculate an address outside buffer.
10792 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
10793 Don't access memory outside of the args array.
10794 (Fdefine_coding_system_internal): Check for charset-id overflow.
10795 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
10796 result of ENCODE_CHAR.
10797 * coding.h: Adjust decls to match defn changes elsewhere.
10798 (struct coding_system):

10815 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
10816 Do not attempt to compute the address of the object just before a
10817 buffer; this is not portable.
10819 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11522 2012-05-17 Juri Linkov <juri@jurta.org>
11524 * search.c (Fword_search_regexp, Fword_search_backward)
11525 (Fword_search_forward, Fword_search_backward_lax)
11526 (Fword_search_forward_lax): Move functions to isearch.el
11527 (bug#10145, bug#11381).
11529 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11531 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11533 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11535 * lread.c (init_obarray): Declare Qt and Qnil as special.
11537 2012-05-14 Glenn Morris <rgm@gnu.org>
11539 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11540 Put "libexec" before "bin", for the sake of init_callproc_1.
11542 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11544 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11546 * unexaix.c: Port to more-recent AIX compilers.
11547 (report_error, report_error_1, make_hdr, copy_sym)
11548 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11549 Make arguments const char *, not char *, to avoid violations of C
11550 standard and to fix some AIX warnings reported by Gilles Pion.
11552 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11554 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11555 already have overlays loaded.
11556 (handle_single_display_spec): Before returning without displaying
11557 fringe bitmap, synchronize the bidi iterator with the main display
11558 iterator, by calling iterate_out_of_display_property.
11559 (iterate_out_of_display_property): Detect buffer iteration by
11560 testing that it->string is a Lisp string.
11561 (get_next_display_element): When the current object is exhausted,
11562 and there's something on it->stack, call set_iterator_to_next to
11563 proceed with what's on the stack, instead of returning zero.
11564 (set_iterator_to_next): If called at the end of a Lisp string,
11565 proceed to consider_string_end without incrementing string
11566 position. Don't increment display vector index past the end of
11567 the display vector. (Bug#11417)
11568 (pos_visible_p): Don't report a position visible when move_it_to
11569 stopped at the last line of window, which happens to be scanned
11570 backwards by the bidi iteration. (Bug#11464)
11572 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11574 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11575 and right-margin display specs even if the spec is invalid or we
11576 are on a TTY, and thus unable to display on the fringes.
11577 That's because the text with the property will not be displayed anyway,
11578 so we need to signal to the caller that this is a "replacing"
11579 display spec. This fixes display when the spec is invalid or we
11582 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11584 * unexaix.c (make_hdr): Fix typo in prototype.
11585 This bug broke the build on AIX. Problem reported by Gilles Pion.
11587 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11589 * keyboard.c (kbd_buffer_get_event): Read special events also in
11590 batch mode. (Bug#11415)
11592 2012-05-12 Glenn Morris <rgm@gnu.org>
11594 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11596 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11598 * lisp.mk (lisp): Add newcomment.elc.
11600 2012-05-12 Glenn Morris <rgm@gnu.org>
11602 * Makefile.in (MKDIR_P): New, set by configure.
11603 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11605 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11607 Remove unused function hourglass_started.
11608 * dispextern.h (hourglass_started):
11609 * w32fns.c (hourglass_started):
11610 * xdisp.c (hourglass_started): Remove.
11612 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11614 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11615 Update dependencies.
11617 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11619 * xgselect.c (xg_select): Put maxfds+1 into a var.
11620 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11622 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11624 2012-05-10 Dave Abrahams <dave@boostpro.com>
11626 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11627 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11629 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11631 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11632 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11633 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11634 Initialize xd_registered_buses.
11636 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11638 Untag more efficiently if USE_LSB_TAG.
11639 This is based on a proposal by YAMAMOTO Mitsuharu in
11640 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11641 For an admittedly artificial (nth 8000 longlist) benchmark on
11642 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11643 Emacs's overall text size by 1%.
11644 * lisp.h (XUNTAG): New macro.
11645 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11646 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11647 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11648 * eval.c (Fautoload):
11649 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11650 * frame.h (XFRAME): Use XUNTAG.
11652 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11653 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11654 Remove unportable assumptions about print widths of types like
11656 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11657 intptr_t when converting between pointer and integer, to avoid GCC
11658 warnings about wrong width.
11660 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11662 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11663 stack for each reader_thread, instead of defaulting to 8MB
11664 determined by the linker. This avoids failures in creating
11665 subprocesses on Windows 7, see the discussion in this thread:
11666 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11668 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11670 Fix up display of the *Minibuf-0* buffer in the mini window.
11671 * keyboard.c (read_char): Don't clear the echo area if there's no
11673 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11674 contents of *Minibuf-0*) if there's no message displayed in its stead.
11676 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11678 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11681 2012-05-06 Chong Yidong <cyd@gnu.org>
11683 * lisp.mk (lisp): Update.
11685 2012-05-05 Jim Meyering <meyering@redhat.com>
11687 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11689 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11691 * data.c (PUT_ERROR): New macro.
11692 (syms_of_data): Use it. Add new error type `user-error'.
11693 * undo.c (user_error): New function.
11694 (Fprimitive_undo): Use it.
11695 * print.c (print_error_message): Adjust print style for `user-error'.
11696 * keyboard.c (user_error): New function.
11697 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11699 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11701 Do not limit current-time-string to years 1000..9999.
11702 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11703 (Fcurrent_time_string): Support any year that is supported by the
11704 underlying localtime representation. Don't use asctime, as it
11705 has undefined behavior for years outside the range -999..9999.
11707 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11709 Fix race conditions involving setenv, gmtime, localtime, asctime.
11710 Without this fix, interrupts could mess up code that uses these
11711 nonreentrant functions, since setting TZ invalidates existing
11712 tm_zone or tzname values, and since most of these functions return
11713 pointers to static storage.
11714 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11715 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11716 Grow the critical sections to include not just invoking
11717 localtime/gmtime, but also accessing these functions' results
11718 including their tm_zone values if any, and any related TZ setting.
11719 (format_time_string): Last arg is now struct tm *, not struct tm **,
11720 so that the struct tm is saved in the critical section.
11721 All callers changed. Simplify allocation of initial buffer, partly
11722 motivated by the fact that memory allocation needs to be outside
11723 the critical section.
11725 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11727 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11728 with RESET_INTERVAL.
11730 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11731 Remove duplicated buffer name initialization.
11733 2012-05-02 Jim Meyering <jim@meyering.net>
11735 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11737 * xfns.c (x_window): Use xstrdup (Bug#11375).
11739 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11741 * xdisp.c (pos_visible_p): If already at a newline from the
11742 display string before the 'while' loop, don't walk back the glyphs
11743 from it3.glyph_row. Solves assertion violation when the display
11744 string begins with a newline (egg.el). (Bug#11367)
11746 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11748 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11751 2012-05-01 Glenn Morris <rgm@gnu.org>
11753 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11754 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11755 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11756 All were removed before 23.1.
11758 * dispnew.c: Remove HAVE_LIBNCURSES test;
11759 it is always true on relevant platforms.
11761 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11762 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11764 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11766 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11768 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11769 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11772 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11774 Do not avoid creating empty evaporating overlays (Bug#9642).
11775 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11776 That is, do not delete an evaporating overlay if it becomes
11777 empty after its bounds are adjusted to fit within its buffer.
11778 This fix caused other problems, and I'm reverting it until we get
11779 to the bottom of them.
11781 2012-04-27 Chong Yidong <cyd@gnu.org>
11783 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11785 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11787 * xdisp.c (pos_visible_p): If the window start position is beyond
11788 ZV, start the display from buffer beginning. Prevents assertion
11789 violation in init_iterator when the minibuffer window is scrolled
11790 via the scroll bar.
11792 * window.c (window_scroll_pixel_based): Likewise.
11794 2012-04-27 Chong Yidong <cyd@gnu.org>
11796 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11798 2012-04-27 Glenn Morris <rgm@gnu.org>
11800 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11801 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11803 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11805 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11806 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11808 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11810 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11811 display element, check also the underlying string or buffer
11812 character. (Bug#11341)
11814 * w32menu.c: Include w32heap.h.
11815 (add_menu_item): If the call to AppendMenuW (via
11816 unicode_append_menu) fails, disable Unicode menus only if we are
11817 running on Windows 9X/Me.
11819 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11821 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11822 (xgetint): Add missing shift for LSB tags.
11824 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11826 * keyboard.c (read_char): Don't wipe echo area for select window
11827 events: These might get delayed via `mouse-autoselect-window'
11830 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11832 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11833 manipulation of :loaded-from data.
11835 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11837 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11838 now a cons (bug#11311).
11840 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11842 Do not create empty overlays with the evaporate property (Bug#9642).
11843 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11844 if it becomes empty after its bounds are adjusted to fit within
11845 its buffer. Without this fix, in a nonempty buffer (let ((o
11846 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11847 yields an empty overlay that has the evaporate property, which is
11848 not supposed to happen.
11850 Fix minor GTK3 problems found by static checking.
11851 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11852 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11853 (struct _EmacsFixedClass, emacs_fixed_get_type):
11854 Move decls here from emacsgtkfixed.h, since they needn't be public.
11855 (emacs_fixed_get_type): Now static.
11856 (emacs_fixed_class_init): Omit unused local.
11857 (emacs_fixed_child_type): Remove; unused.
11858 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11859 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11860 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11861 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11862 (EMACS_FIXED_GET_CLASS): Remove; unused.
11863 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11865 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11866 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11868 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11870 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11871 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11872 (__malloc_size_t, __malloc_ptrdiff_t):
11873 Remove. All uses removed, replaced by the definiens if needed,
11874 since we can assume C89 or better now.
11875 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

11883 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11884 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11885 Define using prototypes, not old style.
11886 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11887 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11888 (align): Don't assume that signed integer overflow wraps around.
11889 Omit unused local var.
11890 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
11891 (_free_internal_nolock, memalign, mallochook, reallochook):
11892 Omit no-longer-needed casts.
11893 (valloc): Use getpagesize, not __getpagesize.
11894 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11895 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11897 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11899 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11901 Move functions from C to Lisp. Make non-blocking method calls
11902 the default. Implement further D-Bus standard interfaces.
11904 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

11920 (xd_signature, xd_append_arg): Allow float for integer types.
11921 (xd_get_connection_references): New function.
11922 (xd_get_connection_address): Rename from xd_initialize.
11923 Return cached address.
11924 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
11925 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp
11927 (Fdbus_init_bus): New optional arg PRIVATE. Cache address.
11928 Return number of refcounts.
11929 (Fdbus_get_unique_name): Make stronger parameter check.
11930 (Fdbus_message_internal): New defun.

11932 (Fdbus_method_return_internal, Fdbus_method_error_internal)
11933 (Fdbus_send_signal, Fdbus_register_service)

11944 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11946 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
11947 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
11948 Do not assume ptrdiff_t is the same width as 'int'.
11950 * alloc.c: Handle unusual debugging option combinations.
11951 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
11952 since the two debugging options are incompatible.
11953 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

11963 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11965 * sysdep.c [__FreeBSD__]: Minor cleanups.
11966 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11967 Use Emacs indenting style more consistently. Avoid some casts.
11968 Use 'double' consistently rather than mixing 'float' and 'double'.
11970 2012-04-21 Eduard Wiebe <usenet@pusto.de>
11972 * sysdep.c (list_system_processes, system_process_attributes):
11973 Add implementation for FreeBSD (Bug#5243).

11979 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
11981 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
11982 It is never used otherwise.
11984 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
11986 * print.c (print_preprocess): Only check print_depth if print-circle
11988 (print_object): Check for cycles even when print-circle is nil and
11989 print-gensym is t, but only check print_depth if print-circle is nil.
11991 2012-04-20 Chong Yidong <cyd@gnu.org>
11993 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11994 set the status to "failed" and ensure that sentinel is run.
11996 2012-04-20 Glenn Morris <rgm@gnu.org>
11998 * process.c (Fset_process_inherit_coding_system_flag)
11999 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

12009 farther than the first row after the header line, if any.
12010 Don't consider the header-line row as "partially visible", even if
12011 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
12013 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

12022 * Makefile.in (C_WARNINGS_SWITCH): Remove.
12023 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
12024 (ALL_CFLAGS): Use new macros rather than old.
12025 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.

12027 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
12028 -Wunused-result, -Wunused-variable. This should go away once
12029 the Emacs and Gnulib regex code is merged.
12030 (xmalloc, xrealloc): Now static.
12032 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

12049 New extern decls, to avoid calling undeclared functions.
12050 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
12051 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
12052 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
12053 (NEED_MEM_INSERT): New macro.
12054 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
12055 Remove one incorrect comment and fix another.

12069 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
12070 Remove decls. This fixes an "It stinks!".
12072 * alloc.c (which_symbols): Fix alignment issue / type clash.
12074 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
12076 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
12077 (struct Lisp_Misc_Any): Likewise.
12078 (struct Lisp_Free): Likewise.
12079 * alloc.c (union aligned_Lisp_Symbol): Define.

12087 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
12089 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
12090 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
12091 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12092 * s/netbsd.h, s/sol2-6.h:
12093 Remove definition of GC_MARK_STACK, since the default now works.
12094 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12095 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12096 no longer the default.
12097 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12099 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
12101 * lread.c (lisp_file_lexically_bound_p):
12102 Fix hang at ";-*-\n" (bug#11238).
12104 2012-04-14 Eli Zaretskii <eliz@gnu.org>
12106 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
12107 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

12116 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
12118 2012-04-13 Reuben Thomas <rrt@sc3d.org>
12120 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
12122 2012-04-11 Daniel Colascione <dancol@dancol.org>
12124 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12125 against is gone. It's better to use vfork now so that when Cygwin
12126 gains a new, working vfork, we use it automatically (bug#10398).
12128 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
12130 * window.c (save_window_save): Obey window-point-insertion-type.

12146 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
12148 * w32.c (w32_delayed_load): Record the full path of the library
12149 being loaded (bug#10424).
12151 2012-04-09 Glenn Morris <rgm@gnu.org>
12153 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12154 not just in the obarray, before snarfing them. (Bug#11036)

12157 Pass EMACS rather than BUILT_EMACS.
12159 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
12161 * process.c (make_process):
12162 * process.h: Add integer `gnutls_handshakes_tried' member to
12165 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.

12168 * gnutls.c (gnutls_log_function2i): Convenience log function.
12169 (emacs_gnutls_read): Use new log functions,
12170 `gnutls_handshakes_tried' process member, and
12171 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12172 attempts per process (connection).
12174 2012-04-09 Chong Yidong <cyd@gnu.org>
12176 * eval.c (Fuser_variable_p, user_variable_p_eh)
12177 (lisp_indirect_variable): Functions deleted.
12178 (Fdefvar): Caller changed.
12180 * callint.c (Finteractive, Fcall_interactively):
12181 * minibuf.c (Fread_variable): Callers changed.
12183 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12185 * xdisp.c (set_cursor_from_row): If the display string appears in
12186 the buffer at position that is closer to point than the position
12187 after the display string, display the cursor on the first glyph of
12188 the display string. Fixes cursor display when a 'display' text
12189 property immediately follows invisible text. (Bug#11094)
12191 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12193 composite.c: use 'double' consistently
12194 * composite.c (get_composition_id): Use 'double' consistently
12195 instead of converting 'float' to 'double' and vice versa; this is
12196 easier to understand and avoids a GCC warning.
12198 2012-04-09 Glenn Morris <rgm@gnu.org>
12200 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12201 preparation for dumping it with emacs. (Bug#4789)
12202 (leimdir): New variable.
12203 ($(leimdir)/leim-list.el): New rule.
12204 (emacs$(EXEEXT)): Depend on leim-list.el.

12222 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12223 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12224 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12225 objects, as mark_maybe_pointer will catch them otherwise.
12226 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12227 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

12234 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12236 Support building on MS-Windows with libxml2.
12238 * makefile.w32-in (OBJ2): Add xml.$(O).
12239 (GLOBAL_SOURCES): Add xml.c.
12240 ($(BLD)/xml.$(O)): New dependency list.
12242 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12243 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12244 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12245 [!WINDOWSNT]: New macros.
12246 (init_libxml2_functions, libxml2_loaded_p): New functions.
12247 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12248 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12249 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12250 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12252 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12253 Call init_libxml2_functions before calling libxml2 functions.
12254 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12256 * emacs.c: Don't include libxml/parser.h.
12257 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12258 xmlCleanupParser directly.
12260 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12262 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12264 * indent.c (Fvertical_motion): If there is a display string at
12265 point, use it.vpos to compute how many lines to backtrack after
12266 move_it_to point. (Bug#11133)
12268 2012-04-06 Eli Zaretskii <eliz@gnu.org>
12270 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
12271 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
12272 about subtle differences between FETCH_CHAR* and STRING_CHAR*
12273 macros related to unification of CJK characters. For the details,
12274 see the discussion following the message here:
12275 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
12277 2012-04-04 Chong Yidong <cyd@gnu.org>
12279 * keyboard.c (Vdelayed_warnings_list): Doc fix.
12281 2012-04-01 Eli Zaretskii <eliz@gnu.org>
12283 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
12284 instead of alloca. (Bug#11138)
12286 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
12288 * w32menu.c (is_simple_dialog): Properly check lisp types.
12291 2012-03-31 Eli Zaretskii <eliz@gnu.org>
12293 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
12294 position we get to after a call to move_it_to fails the
12295 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
12296 only if we wind up in a string from display property. (Bug#11063)
12298 * window.c (Fdelete_other_windows_internal): Invalidate the row
12299 and column information about mouse highlight, so that redisplay
12300 restores it after reallocating the glyph matrices. (Bug#7464)
12302 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
12303 string comes from a `display' text property, use the buffer
12304 position of that property as if we actually saw that position in
12306 (move_it_by_lines): Remove the assertion that
12307 "it->current_x == 0 && it->hpos == 0" which can be legitimately
12308 violated when there's a before-string at the beginning of a line.
12311 2012-03-30 Eli Zaretskii <eliz@gnu.org>
12313 * xdisp.c (append_space_for_newline): If the default face was
12314 remapped, use the remapped face for the appended newline.
12315 (extend_face_to_end_of_line): Use the remapped default face for
12316 extending the face to the end of the line.
12317 (display_line): Call extend_face_to_end_of_line when the default
12318 face was remapped. (Bug#11068)
12320 2012-03-29 Eli Zaretskii <eliz@gnu.org>
12322 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
12324 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
12326 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
12328 2012-03-27 Glenn Morris <rgm@gnu.org>
12330 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
12333 2012-03-26 Kenichi Handa <handa@m17n.org>

12340 * keyboard.c (Vselection_inhibit_update_commands): New variable.
12341 (command_loop_1): Use it; inhibit selection update for
12342 handle-select-window too (Bug#8996).

12346 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
12348 2012-03-25 Kenichi Handa <handa@m17n.org>
12350 * dispextern.h (struct glyph): Change the bit length of
12351 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
12353 2012-03-24 Eli Zaretskii <eliz@gnu.org>
12355 * s/ms-w32.h (tzname): Include time.h before redirecting to
12356 _tzname. Fixes the MSVC build. (Bug#9960)
12358 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
12360 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
12363 * xterm.c (XTread_socket): Only modify handling_signal if
12364 !SYNC_INPUT. (Bug#11080)
12366 2012-03-23 Eli Zaretskii <eliz@gnu.org>
12368 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
12369 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
12370 when fetching a multibyte character consumes more bytes than
12371 CHAR_BYTES returns, due to unification of CJK characters in
12372 string_char. (Bug#11073)
12374 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
12376 * process.c (wait_reading_process_output): Handle pty disconnect
12377 by refraining from sending oneself a SIGCHLD (bug#10933).
12379 2012-03-22 Chong Yidong <cyd@gnu.org>
12381 * dispextern.h (struct it): New member string_from_prefix_prop_p.
12383 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
12384 Mark string as coming from a prefix property.
12385 (handle_face_prop): Use default face for prefix strings (Bug#4281).
12386 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
12388 2012-03-21 Chong Yidong <cyd@gnu.org>
12390 * xfaces.c (Vface_remapping_alist): Doc fix.
12392 2012-03-20 Eli Zaretskii <eliz@gnu.org>
12394 * w32proc.c (Fw32_set_console_codepage)
12395 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

12405 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
12406 it fit in a valid range (Bug#11003).
12408 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12410 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12411 that is not from display property, accept the row as a "cursor
12412 row" if one of the string's character has a non-nil `cursor'
12413 property. Fixes cursor positioning when there are newlines in
12414 overlay strings, e.g. in icomplete.el. (Bug#11035)
12416 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

12450 2012-03-03 Glenn Morris <rgm@gnu.org>
12452 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12454 2012-03-02 Eli Zaretskii <eliz@gnu.org>

12458 (redisplay_window, next_element_from_string): Fix typos in
12460 (redisplay_window): Pass to move_it_vertically the margin in

12465 * buffer.c (buffer-list-update-hook): Doc fix.
12467 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12469 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12470 push_it before setting up the iterator for the first overlay
12471 string, even if we have an empty string loaded.
12472 (next_overlay_string): If there's an empty string on the iterator
12473 stack, pop the stack. (Bug#10903)
12475 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12477 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12478 Suggested by Stefan Monnier in
12479 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12480 * alloc.c (widen_to_Lisp_Object): New static function.
12481 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12482 and widening them to Lisp_Objects. This would work even if
12483 USE_LSB_TAG is defined and wide integers are used, which might
12484 happen in a future version of Emacs.
12486 2012-02-25 Chong Yidong <cyd@gnu.org>
12488 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

12497 * keyboard.c (process_special_events): Handle all X selection
12498 requests in kbd_buffer, not just the next one (Bug#8869).
12500 2012-02-23 Chong Yidong <cyd@gnu.org>
12502 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12503 call when setting menu-bar-lines and tool-bar-lines parameters.
12504 (unwind_create_frame_1): New helper function.
12506 * window.c (inhibit_window_configuration_change_hook): New var.
12507 (run_window_configuration_change_hook): Obey it.

12525 when computing $valmask.
12527 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12528 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12529 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12530 It's useless in that case, and it can cause problems on hosts
12531 that allocate halves of EMACS_INT values separately.
12532 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12533 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12534 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12535 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12536 it avoids undefined behavior on hosts where shifting right by more
12537 than the word width has undefined behavior.
12539 2012-02-19 Chong Yidong <cyd@gnu.org>
12541 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12542 (Funhandled_file_name_directory, Ffile_name_as_directory)
12543 (Fdirectory_file_name, Fexpand_file_name)
12544 (Fsubstitute_in_file_name): Protect against invalid file handler
12545 return values (Bug#10845).

12561 2012-02-15 Chong Yidong <cyd@gnu.org>
12563 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

12579 2012-02-12 Chong Yidong <cyd@gnu.org>
12581 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12582 as that creates a dangerous corner case.
12584 * window.c (Fdelete_window_internal): Invalidate the mouse
12585 highlight (Bug#9904).
12587 2012-02-12 Glenn Morris <rgm@gnu.org>

12617 2012-02-07 Chong Yidong <cyd@gnu.org>
12619 * buffer.c (Fbuffer_local_variables)
12620 (buffer_lisp_local_variables): Handle unbound vars correctly;
12621 don't let Qunbound leak into Lisp.
12623 2012-02-07 Glenn Morris <rgm@gnu.org>
12625 * image.c (Fimagemagick_types): Doc fix.
12627 * image.c (imagemagick-render-type): Change it from a lisp object
12628 to an integer. Move the doc here from the lisp manual.

12658 before BEGV. (Bug#10696)
12660 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
12662 Handle overflow when computing char display width (Bug#9496).
12663 * character.c (char_width): Return EMACS_INT, not int.
12664 (char_width, c_string_width): Check for overflow when
12665 computing the width; this is possible now that individual
12666 characters can have unbounded width. Problem introduced
12667 by merge from Emacs 23 on 2012-01-19.

12691 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
12693 (x_produce_glyphs): If the component of a composition is a null

12698 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
12699 first 2 arguments are identical. This makes inserting large
12700 output from a subprocess an order of magnitude faster on
12701 MS-Windows, where all sbrk'ed memory is always contiguous.

12801 DISP_STRING, and accept any glyph in a row whose object is that
12802 string as eligible for mouse highlight. Fixes mouse highlight of
12803 display strings from overlays. (Bug#10464)
12805 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
12807 emacs: fix an auto-save permissions race condition (Bug#10400)

12809 (Fmake_directory_internal): Use it.

13154 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
13155 verifies glyph row's hash code--we have just reallocated the

13320 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
13321 is set, removing the need for VIRT_ADDRESS_VARIES.
13322 (PURE_P): Use a more-efficient implementation that needs just one

13325 to 4 (xorl, subq, cmpq, setbe).
13326 * alloc.c (pure): Always extern now, since that's the

13330 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

13337 (erase_phys_cursor, update_window_cursor, show_mouse_face)
13338 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
13339 behave as if the cursor position were at the window margin.
13341 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
13342 and the cursor position is out of bounds, behave as if the cursor
13343 position were at the window margin. (Bug#10075)
13345 2011-11-18 Chong Yidong <cyd@gnu.org>
13347 * window.c (Fwindow_combination_limit): Make first argument

13571 static_offset_intervals. The old version didn't conform to C99
13572 because an extern inline function contained a reference to an

13823 2011-10-27 Chong Yidong <cyd@gnu.org>
13825 * process.c (make_process): Set gnutls_state to NULL.
13827 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13828 non-NULL, regardless of GNUTLS_INITSTAGE.
13829 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13830 an error. Set process slots as soon as we allocate them.
13832 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13834 2011-10-27 Chong Yidong <cyd@gnu.org>
13836 * gnutls.c (emacs_gnutls_deinit): New function.
13837 Deallocate credentials structures as well as calling gnutls_deinit.
13838 (Fgnutls_deinit, Fgnutls_boot): Use it.
13840 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13841 (deactivate_process): Call emacs_gnutls_deinit.
13843 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13845 * image.c (x_create_x_image_and_pixmap):
13846 * w32.c (sys_rename, w32_delayed_load):
13847 * w32font.c (fill_in_logfont):
13848 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13850 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13852 * w32fns.c (w32_default_color_map): New function,
13853 extracted from Fw32_default_color_map.
13854 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13856 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13858 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13860 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13862 * keyboard.c (test_undefined): New function (bug#9751).
13863 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13865 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13867 * sysdep.c (init_sys_modes): Fix the check for the controlling
13868 terminal (Bug#6649).
13870 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13872 * dispextern.h (struct bidi_it): New member next_en_type.
13874 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13875 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13876 current character, check also for next_en_type being WEAK_EN.
13877 (bidi_resolve_weak): Don't enter the expensive loop if the current
13878 position is before next_en_pos. Record the bidi type of the first
13879 non-ET, non-BN character we find, in addition to its position.
13880 (bidi_level_of_next_char): Invalidate next_en_type when
13881 next_en_pos is over-stepped.
13883 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13885 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13886 * editfns.c: Rewrite current-time-zone so that it invokes
13887 the equivalent of (format-time-string "%Z") to get the time zone name.
13888 This fixes a bug when the time zone name contains characters that
13889 need converting from the system time locale to Emacs internal format.
13890 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13891 that patch fixed format-time-string to do the conversion, but
13892 I forgot to fix current-time-zone.
13893 (format_time_string): New function, containing most of
13894 what Fformat_time_string used to contain.
13895 (Fformat_time_string): Rewrite in terms of format_time_string.
13896 This doesn't change this function's behavior.
13897 (current-time-zone): Rewrite to use format_time_string.
13898 This fixes the bug reported by Michael Schierl in
13899 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13900 Jason Rumney's 2007-06-07 change worked around this bug, but
13902 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13904 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13906 * xdisp.c (start_display): If the character at POS is displayed
13907 via a display vector, reset IT->current.dpvec_index to zero.
13908 (try_window_reusing_current_matrix): If a line ends in a display
13909 vector or the next line starts in a display vector, continue
13910 redrawing the window even though the character position of
13911 start_row was reached.
13914 2011-10-18 Chong Yidong <cyd@gnu.org>
13916 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13917 with nobreak-char-display too.
13919 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13921 Fix part 3 of bug#9771.
13922 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13923 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13924 non-neutral characters if the current character is a paragraph
13925 separator (a.k.a. Newline). This avoids running the same
13926 expensive loop twice, once when we consume the preceding newline
13927 and the other time when the line actually needs to be displayed.
13928 Avoid the loop when we see neutrals on the base embedding level
13929 following a character whose directionality is the same as the
13930 paragraph's. This avoids running the expensive loop when a line
13931 ends in a long sequence of neutrals, like control characters.
13932 Add assertion against STRONG_AL type. Slightly rearrange code
13933 that determines the type of a neutral given the first non-neutral
13935 (bidi_level_of_next_char): Set next_en_pos to zero when
13936 invalidating its info.
13938 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13940 * xdisp.c (push_display_prop): Determine whether to record string
13941 or buffer position by IT->string, not by IT->method. Allow
13942 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13943 (move_it_vertically_backward): Don't look for character position
13944 immediately after the newline when in a continuation line.
13947 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13949 * window.c (coordinates_in_window): Rewrite and delabelize
13950 vertical border check. (Bug#5357) (Bug#9618)
13952 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13954 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13955 errors in XSetWindowBorder (bug#9310).
13957 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13959 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13960 avoid crash when xmalloc overrun checking is enabled.
13962 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13964 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13965 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13966 cursor motion with <left> and <right> arrow keys.
13968 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13969 some callers set that themselves.
13971 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13973 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13974 display string and the previous row comes from the same string and
13975 is empty. (Bug#9739) (Bug#9738)
13977 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13979 * doc.c (get_doc_string): Encode file name (bug#9735).
13981 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13983 * bidi.c (bidi_level_of_next_char):
13984 * xdisp.c (get_visually_first_element): Remove old incorrect
13985 comments regarding the Unicode Line Separator character.
13987 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13989 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13991 * alloc.c (Fgc_status): Do not access beyond zombies array
13992 boundary if nzombies > MAX_ZOMBIES.
13993 * alloc.c (dump_zombies): Add missing format specifier.
13995 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13997 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13998 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14000 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14001 Some packages use them to denote characters with modifiers.
14003 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14005 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14006 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14007 matching a pp-number. Rename parameter var to var1.
14009 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14011 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14013 2011-10-08 Glenn Morris <rgm@gnu.org>
14015 * callint.c (Fcall_interactively): Give a more explicit error for the
14016 'c' case with a non-character input. (Bug#8479)
14018 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14020 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14022 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14023 lines that are hscrolled on the left.
14025 * dispnew.c (buffer_posn_from_coords): Account for a possible
14026 presence of header-line. (Bug#4426)
14028 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14030 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14031 Don't advertise functionality which we discourage or doesn't work.
14033 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14035 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14036 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14037 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14038 this makes Emacs dump core during garbage collection on rare
14039 occasions. sizeof is obviously inferior to offsetof here, so
14040 stick with offsetof.
14041 (GC_POINTER_ALIGNMENT): New macro.
14042 (mark_memory): Omit 3rd (offset) arg; caller changed.
14043 Don't assume EMACS_INT alignment is the same as pointer alignment.
14045 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14047 * keyboard.c (read_key_sequence_remapped): New var.
14048 (read_key_sequence): Compute remapping in the right buffer.
14049 (command_loop_1): Use read_key_sequence's remapping directly.
14051 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14053 * dired.c (file_name_completion): Don't expand file name.
14054 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14055 before checking file name handler.
14057 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14058 they've been requested explicitly (bug#9591).
14060 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14062 * keymap.c (Fsingle_key_description): Use make_specified_string
14063 instead of build_string to build string from push_key_description.
14066 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14068 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14069 This fixes a Y2038 bug on 64-bit hosts.
14070 * buffer.c (reset_buffer):
14071 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14072 (Fclear_buffer_auto_save_failure):
14073 Use 0, not -1, to represent an unset failure time, since time_t
14074 might not be signed.
14076 Remove dependency on glibc malloc internals.
14077 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14078 Move back here from lisp.h, but with their new implementations.
14079 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14080 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14081 * charset.c (charset_table_init): New static var.
14082 (syms_of_charset): Use it instead of xmalloc. This removes a
14083 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14084 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14085 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14086 Move back to alloc.c.
14087 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14088 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14090 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14092 * nsterm.m (windowDidResize): Call x_set_window_size only when
14093 ns_in_resize is true. Otherwise set pixelwidth/height and
14094 call change_frame_size (Bug#9628).
14096 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14098 Port --enable-checking=all to Fedora 14 x86-64.
14099 * charset.c (syms_of_charset): Also account for glibc malloc's
14100 internal overhead when calculating the initial malloc maximum.
14102 Port --enable-checking=all to Fedora 14 x86.
14103 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14105 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14106 (overrun_check_realloc, overrun_check_free):
14107 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14108 That way, xmalloc returns a properly-aligned pointer even if
14109 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14110 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14111 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14112 into account when calculating the initial malloc maximum.
14113 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14114 Move here from alloc.c, so that charset.c can use it too.
14115 Properly align; the old code wasn't right for common 32-bit hosts
14116 when configured with --enable-checking=all.
14117 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14118 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14120 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14122 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14125 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14127 * xdisp.c (compute_display_string_end): If there's no display
14128 string at CHARPOS, return -1.
14130 * bidi.c (bidi_fetch_char): When compute_display_string_end
14131 returns a negative value, treat the character as a normal
14132 character not covered by a display string. (Bug#9624)
14134 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14136 * lread.c (Fread_from_string): Fix typo in docstring.
14138 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14140 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14141 newline, reseat the iterator instead of bidi-iterating there one
14142 character at a time. (Bug#9610)
14143 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14144 TO_CHARPOS if the bidi iterator is at base embedding level.
14146 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14148 * lread.c (readevalloop): Use correct code for NBSP.
14149 (read1): Likewise. (Bug#9608)
14151 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14153 * dbusbind.c (Fdbus_register_signal): When service is not
14154 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14156 2011-09-25 Glenn Morris <rgm@gnu.org>
14158 * buffer.c (truncate-lines): Doc fix.
14160 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14162 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14163 (Fset_window_next_buffers): Doc fix.
14165 2011-09-24 Glenn Morris <rgm@gnu.org>
14167 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14169 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14171 Fix minor problems found by static checking.
14172 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14173 * indent.c (Fvertical_motion): Fix == vs = typo.
14175 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14177 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14178 Default value is now t. Doc fix.
14180 * indent.c (Fvertical_motion): Compute and apply the overshoot
14181 logic when moving up, not only when moving down. Fix the
14182 confusing name and values of the it_overshoot_expected variable;
14183 logic changes accordingly. (Bug#9254) (Bug#9549)
14185 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14186 CHARPOS is covered by a display string which includes newlines.
14187 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14188 is covered by a display string with embedded newlines.
14190 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14192 * dbusbind.c (Fdbus_register_signal): Add match rule to
14193 Vdbus_registered_objects_table. (Bug#9581)
14194 (Fdbus_register_method, Vdbus_registered_objects_table):
14197 2011-09-24 Jim Meyering <meyering@redhat.com>
14199 do not ignore write error for any output size
14200 The previous change was incomplete.
14201 While it makes emacs --batch detect the vast majority of stdout
14202 write failures, errors were still ignored whenever the output size is
14203 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14204 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14205 && echo FAIL: ignored write error
14206 FAIL: ignored write error
14207 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14208 && echo FAIL: ignored write error
14209 FAIL: ignored write error
14210 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14212 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14214 * emacs.c (Fkill_emacs): In noninteractive mode exit
14215 non-successfully if a write error occurred on stdout. (Bug#9574)
14217 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14219 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14222 * dispextern.h (struct it): Update the comment documenting what
14225 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14227 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14228 a display string, extend search for cursor position to end of row.
14229 (find_row_edges): If the row ends in a newline from a display
14230 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14231 Handle the case of a display string with multiple newlines.
14232 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14233 non-empty line. Fixes confusing cursor motion with arrow keys at
14234 the beginning of a line that starts with whitespace.
14236 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14238 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14241 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14243 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14244 boolean (Bug#9154).
14246 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14248 * xdisp.c (display_line): Record maximum and minimum buffer
14249 positions even if no glyphs were produced (e.g., by a zero-width
14250 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14251 buffer positions that will be removed from the glyph row because
14253 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14254 column is beyond frame width: don't subtract 1 "pixel" when
14255 computing width of the stretch.
14256 (reseat_at_next_visible_line_start): Undo the change made on
14257 2011-09-17 that saved paragraph information and restored it after
14258 the call to `reseat'. (Bug#9545)
14260 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14262 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14263 and turn window cursor on if cleared (Bug#9415).
14265 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
14267 * search.c (boyer_moore): Take unibyte characters from pattern
14268 literally. (Bug#9458)
14270 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14272 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
14274 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
14276 Fix minor problem found by static checking.
14277 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
14278 initialized, to pacify gcc -Wuninitialized.
14280 * fileio.c: Report proper errno when syscall falls.
14281 (Finsert_file_contents): Save and restore errno,
14282 so that report_file_error outputs the correct diagnostic.
14283 (Fwrite_region) [CLASH_DETECTION]: Likewise.
14285 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14287 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
14289 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14291 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
14292 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
14294 2011-09-17 Eli Zaretskii <eliz@gnu.org>
14296 * xdisp.c (reseat_at_next_visible_line_start): Keep information
14297 about the current paragraph and restore it after the call to reseat.
14299 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
14300 (bidi_find_paragraph_start): Search back for paragraph beginning
14301 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
14302 (bidi_move_to_visually_next): Only trigger paragraph-related
14303 computations when the last character is a newline or at EOB, not
14304 just any NEUTRAL_B. (Bug#9470)
14306 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
14307 truncated lines if point is covered by a display string. (Bug#9524)
14309 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
14311 * xselect.c: Relax test for outgoing X longs (Bug#9498).
14312 (cons_to_x_long): New function.
14313 (lisp_data_to_selection_data): Use it. Correct the test for
14314 short-versus-long data; it was negated. Break out of vector
14315 loop, for efficiency, when a long datum is discovered.
14317 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
14319 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
14321 2011-09-16 Eli Zaretskii <eliz@gnu.org>
14323 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
14324 GCC PR/17406) by declaring this function with external scope.
14326 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14328 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
14329 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
14331 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
14333 * editfns.c (Fformat): Correctly handle text properties on "%%".
14335 2011-09-15 Eli Zaretskii <eliz@gnu.org>
14337 * xterm.c (x_draw_composite_glyph_string_foreground):
14338 * w32term.c (x_draw_composite_glyph_string_foreground):
14339 * term.c (encode_terminal_code):
14340 * composite.c (composition_update_it, get_composition_id):
14341 * xdisp.c (get_next_display_element)
14342 (fill_composite_glyph_string): Add comments about special meaning
14343 of TAB characters in a composition.
14345 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
14347 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
14348 This occurs when processing a multibyte format.
14349 Problem reported by Wolfgang Jenker.
14351 2011-09-15 Johan Bockgård <bojohan@gnu.org>
14353 * xdisp.c (try_cursor_movement): Only check for exact match if
14354 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
14356 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14358 Remove unused external symbols.
14359 * dispextern.h (calc_pixel_width_or_height): Remove decl.
14360 * xdisp.c (calc_pixel_width_or_height): Now static.
14361 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
14362 * indent.c (check_display_width):
14363 * w32term.c: Fix comment to match code.
14364 * xterm.c, xterm.h (x_catching_errors): Remove.
14366 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
14368 * xselect.c: Use signed conversions more consistently (Bug#9498).
14369 (selection_data_to_lisp_data): Assume incoming selection data are
14370 signed integers, not unsigned. This is to be consistent with
14371 outgoing selection data, which was modified to use signed integers
14372 in as part of the fix to Bug#9196 in response to Jan D.'s comment
14373 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
14374 expects long, not unsigned long.
14376 2011-09-14 Eli Zaretskii <eliz@gnu.org>
14378 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
14379 computation of loop end. Reported by Johan Bockgård
14382 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
14384 * frame.c (Fother_visible_frames_p): Function deleted.
14386 2011-09-12 Eli Zaretskii <eliz@gnu.org>
14388 * indent.c (compute_motion): Process display vector front to back
14389 rather than the other way around. (Bug#2496)
14391 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
14393 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
14395 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14397 * minibuf.c (Fread_from_minibuffer): Doc fix.
14399 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14401 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14402 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14404 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14406 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14407 value for non-existent files.
14409 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14411 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14412 set its "size" to -1. This will set the modtime_size field of
14413 the corresponding buffer to -1, which is what
14414 verify-visited-file-modtime expects for files that do not exist.
14417 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14419 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14421 * lisp.h: ... from here. push_key_description is no longer
14422 defined in keyboard.c, so its declaration should not be in
14423 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14424 logically belongs with push_key_description.
14426 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14428 * buffer.h: Include <sys/types.h> instead of <time.h>.
14429 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14430 Problem reported by Herbert J. Skuhra.
14432 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14434 * xml.c (parse_region): Make the parsing work for
14435 non-comment-starting XML files again (bug#9144).
14437 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14439 * image.c (gif_load): Fix calculation of bottom and right corner.
14442 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14444 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14445 redisplay in small windows.
14447 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14449 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14451 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14453 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14454 Operate on live windows only.
14456 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14458 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14460 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14462 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14463 only under bidi iteration.
14465 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14467 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14469 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14471 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14472 Without this fix, the command to link temacs failed due to an
14473 undefined symbol __builtin_isnan. This is because
14474 /usr/include/iso/math_c99.h #defines isnan(x) to
14475 __builtin_isnan(x), but the bundled gcc, which identifies itself
14476 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14478 * floatfns.c (isnan): #undef, and then #define to a clone of
14480 (Fisnan): Always define, since it's always available now.
14481 (syms_of_floatfns): Always define isnan at the Lisp level.
14483 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14485 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14487 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14489 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14490 The previous code assumed that file offsets (off_t values) fit in
14491 EMACS_INT variables, which is not true on typical 32-bit hosts.
14492 The code messed up by falsely reporting buffer overflow in cases
14493 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14494 when "big" contains more than 2**29 bytes, even though this
14495 inserts just one byte and does not overflow the buffer.
14496 (Finsert_file_contents): Store file offsets as off_t
14497 values, not as EMACS_INT values. Check for overflow when
14498 converting between EMACS_INT and off_t. When checking for
14499 buffer overflow or for overlap, take the offsets into account.
14500 Don't use EMACS_INT for small values where int suffices.
14501 When checking for overlap, fix a typo: ZV was used where
14502 ZV_BYTE was intended.
14503 (Fwrite_region): Don't assume off_t fits into 'long'.
14504 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14506 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14508 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14510 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14512 sprintf-related integer and memory overflow issues (Bug#9412).
14514 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14515 (esprintf, exprintf, evxprintf): New functions.
14516 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14517 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14518 (modify_event_symbol): Do not assume that the length of
14519 name_alist_or_stem is safe to alloca and fits in int.
14520 (Fexecute_extended_command): Likewise for function name and binding.
14521 (Frecursion_depth): Wrap around reliably on integer overflow.
14522 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14523 since some callers pass EMACS_INT values.
14524 (Fsingle_key_description): Don't crash if symbol name contains more
14525 than MAX_ALLOCA bytes.
14526 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14527 (get_minibuffer): Arg is now EMACS_INT, not int.
14528 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14529 (esprintf, exprintf, evxprintf): New decls.
14530 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14532 * dbusbind.c (signature_cat): New function.
14533 (xd_signature, Fdbus_register_signal):
14534 Do not overrun buffer; instead, report string overflow.
14536 * dispnew.c (add_window_display_history): Don't overrun buffer.
14537 Truncate instead; this is OK since it's just a log.
14539 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14540 even if the time zone offset is outlandishly large.
14541 Don't mishandle offset == INT_MIN.
14543 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14544 when creating daemon; the previous buffer-overflow check was incorrect.
14546 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14547 which has the guts of the old verror function.
14549 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14550 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14552 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14553 (font_unparse_xlfd): Don't blindly alloca long strings.
14554 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14555 fits in int, when using sprintf. Use single snprintf to count
14556 length of string rather than counting it via multiple sprintfs;
14557 that's simpler and more reliable.
14558 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14559 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14560 sprintf, in case result does not fit in int.
14562 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14563 (fontset_from_font): Print it.
14565 * frame.c (tty_frame_count): Now printmax_t, not int.
14566 (make_terminal_frame, set_term_frame_name): Print it.
14567 (x_report_frame_params): In X, window IDs are unsigned long,
14568 not signed long, so print them as unsigned.
14569 (validate_x_resource_name): Check for implausibly long names,
14570 and don't assume name length fits in 'int'.
14571 (x_get_resource_string): Don't blindly alloca invocation name;
14572 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14575 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14576 (xg_check_special_colors, xg_set_geometry):
14577 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14579 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14580 Use esprintf, not sprintf, in case result does not fit in int.
14582 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14583 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14584 it as a large positive number.
14585 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14586 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14588 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14589 in case result does not fit in int.
14591 * print.c (float_to_string): Detect width overflow more reliably.
14592 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14593 buffer overrun. Don't assume list length fits in 'int'. Treat
14594 print length of 0 as 0, not as infinity; to be consistent with other
14595 uses of print length in this function. Don't overflow print length
14596 index. Don't assume hash table size fits in 'long', or that
14597 vectorlike size fits in 'unsigned long'.
14599 * process.c (make_process): Use printmax_t, not int, to format
14600 process-name gensyms.
14602 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14604 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14605 to avoid potential buffer overrun.
14607 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14608 if X resource line is longer than 512 bytes.
14610 * xfns.c (x_window): Make sprintf buffer a bit bigger
14611 to avoid potential buffer overrun.
14613 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14615 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14617 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14619 Integer overflow fixes for scrolling, etc.
14620 Without these, Emacs silently mishandles large integers sometimes.
14621 For example, "C-u 4294967297 M-x recenter" was treated as if
14622 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14624 * xdisp.c (try_window_id): Check Emacs fixnum range before
14625 converting to 'int'.
14627 * window.c (window_scroll_line_based, Frecenter):
14628 Check that an Emacs fixnum is in range before assigning it to 'int'.
14629 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14630 values converted from Emacs fixnums.
14631 (Frecenter): Don't wrap around a line count if it is out of 'int'
14632 range; instead, treat it as an extreme value.
14633 (Fset_window_configuration, compare_window_configurations):
14634 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14636 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14637 that can exceed INT_MAX. Check that EMACS_INT value is in range
14638 before assigning it to the (possibly-narrower) index.
14639 (match_limit): Don't assume that a fixnum can fit in 'int'.
14641 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14644 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14645 (Fvertical_motion): Don't wrap around LINES values that don't fit
14646 in 'int'. Instead, treat them as extreme values. This is good
14647 enough for windows, which can't have more than INT_MAX lines anyway.
14649 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14651 * Require libxml/parser.h to avoid compilation warning.
14653 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14655 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14656 since this reportedly can destroy thread storage.
14658 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14660 * syntax.c (find_defun_start): Update all cache variables if
14661 exiting early (Bug#9401).
14663 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14665 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14667 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14668 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14669 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14671 * term.c (tty_append_glyph): New function.
14672 (produce_stretch_glyph): Static function and its prototype deleted.
14674 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14677 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14679 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14680 when checking :margin (Bug#9390).
14681 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14682 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14683 so that the name doesn't mislead. All uses changed.
14685 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14687 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14690 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14692 * xdisp.c (move_it_to): Don't bail out early when reaching
14693 position beyond to_charpos, if we are scanning backwards.
14694 (move_it_vertically_backward): When DY == 0, make sure we get to
14695 the first character in the line after the newline.
14697 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14699 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14700 (ccl_driver): Do not generate an out-of-range pointer.
14701 (Fccl_execute_on_string): Remove unnecessary check for
14702 integer overflow, noted by Stefan Monnier in
14703 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14704 Remove a FIXME that didn't need fixing.
14705 Simplify the newly-introduced buffer reallocation code.
14707 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14709 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14711 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14713 Integer and memory overflow issues (Bug#9196).
14715 * doc.c (get_doc_string): Rework so that
14716 get_doc_string_buffer_size is the actual buffer size, rather than
14717 being 1 less than the actual buffer size; this makes xpalloc more
14720 * image.c (x_allocate_bitmap_record, cache_image):
14721 * xselect.c (Fx_register_dnd_atom):
14722 Simplify previous changes by using xpalloc.
14724 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14725 since either will do and ptrdiff_t is convenient with xpalloc.
14727 * charset.c (charset_table_size)
14728 (struct charset_sort_data.priority): Now ptrdiff_t.
14729 (charset_compare): Don't overflow if priorities differ greatly.
14730 (Fsort_charsets): Don't assume list length fits in int.
14731 Check for size-calculation overflow when allocating sort data.
14732 (syms_of_charset): Allocate an initial charset table that is
14733 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14735 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14737 * composite.h (struct composition.glyph_len): Now int, not unsigned.

14742 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14743 with xpalloc. The values are still always <= INT_MAX.

14753 (revalidate_region_cache, know_region_cache, region_cache_forward)
14754 (region_cache_backward, pp_cache):
14755 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14756 so that ptrdiff_t * can be passed to xpalloc.
14757 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14758 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

14773 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14775 Don't update size of array until after memory allocation succeeds,
14776 because xmalloc/xrealloc may not return.
14777 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14778 now that we have proper integer overflow checking.
14779 (record_overlay_string, overlay_strings): Catch overflows when
14780 calculating size of overlay_str_buf.
14782 * callproc.c (Fcall_process): Check for size overflow when
14783 calculating size of args2.
14784 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14785 Normally we prefer signed values, but sticking with ptrdiff_t would
14786 require adding more-complicated checks.
14788 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14789 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14790 Redo buffer-overflow calculations to avoid integer overflow.
14791 Add a FIXME comment where memory seems to be over-allocated.
14793 * character.c (Fstring): Check for size-calculation overflow.

14829 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14831 * emacs.c (main): Do not reallocate argv, since there is a null at
14832 the end that can be overwritten, and this way there's no need to
14833 worry about size-calculation overflow.
14834 (sort_args): Check for size-calculation overflow.
14836 * eval.c (init_eval_once, grow_specpdl): Don't update size until

14842 Check for integer overflow.
14843 (x_set_alpha): Do not assume XINT fits in int.
14845 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14846 This is for the members text_lines, text_cols, total_lines, total_cols,
14847 where the system imposes an 'int' limit.
14849 * fringe.c (Fdefine_fringe_bitmap):
14850 Don't update size until alloc works.

14855 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14856 Check for size-calculation overflow.
14857 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14858 do, as we prefer signed integers.

14865 * gtkutil.h: Change prototypes to match the above.
14867 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

14914 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14915 for command line length. Do not attempt to address one before the
14916 beginning of an array, as that's not portable.

14963 (X_LONG_MIN): New macros.
14964 Use them to make the following changes clearer.
14965 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

14967 future maintainers not to raise the value too much later.
14968 (SELECTION_QUANTUM): Remove, replacing with ...
14969 (selection_quantum): ... new function, which avoids overflow.
14971 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

14989 Don't store size until memory allocation succeeds.
14990 (x_get_window_property): Plug memory leak on memory exhaustion.
14991 Don't double-block input; malloc is safe here. Don't assume 2**34
14992 - 4 fits in unsigned long. Add an xassert to check
14993 XGetWindowProperty overflow. Be more careful about overflow
14994 calculations, and distinguish size from memory overflow better.
14995 (receive_incremental_selection): When tracing, don't assume
14996 unsigned int is less than INT_MAX.
14997 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

15000 in the range -65535 through -1 fit in an X unsigned short.
15001 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15002 result parameters unless successful. Rely on cons_to_unsigned
15003 to report problems with elements; the old code wasn't right anyway.
15004 (x_check_property_data): Check for int overflow; we cannot use
15005 a wider type due to X limits.

15038 * lisp.h (hash_lookup, hash_put):
15039 * minibuf.c (Ftest_completion):
15040 Use ptrdiff_t for hash table indexes, not int (which is too
15041 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on

15053 with outlandish widths.
15054 * character.h (sanitize_tab_width): Rename from sanitize_width,

15080 (make_lispy_movement): Use same integer type in forward decl
15081 that is used in the definition.

15083 Change bufsize argument back to int, undoing my 2011-03-30 change.
15084 We prefer signed types, and int is wide enough here.
15085 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15086 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15087 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15088 length, not size_t. Use ptrdiff_t for index, not int.
15089 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15090 possibility of integer overflow.

15118 Prefer int to unsigned where either will do.
15119 (tiff_handler): New function, combining the cores of the
15120 old tiff_error_handler and tiff_warning_handler.
15121 This function is rewritten to use vsnprintf and thereby avoid
15122 stack buffer overflows. It uses only the features of vsnprintf
15123 that are common to both POSIX and native Microsoft.
15124 (tiff_error_handler, tiff_warning_handler): Use it.
15125 (tiff_load, gif_load, imagemagick_load_image):
15126 Don't assume :index value fits in 'int'.

15168 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
15169 buffers, return left-to-right.
15170 (set_cursor_from_row): Consider candidate row a win if its glyph
15171 represents a newline and point is on that newline. Fixes cursor
15172 positioning on the newline at EOL of R2L text within L2R
15173 paragraph, and vice versa.
15174 (try_cursor_movement): Check continued rows, in addition to
15175 continuation rows. Fixes unwarranted scroll when point enters a
15176 continued line of R2L text within an L2R paragraph, or vice versa.
15177 (cursor_row_p): Consider the case of point being equal to
15178 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

15204 * xdisp.c (redisplay_window): When computing centering_position,
15205 account for the height of the header line. (Bug#8874)
15207 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15208 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15209 candidate is selected by the mouse, and that candidate has a
15210 composed character under the mouse.
15212 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15213 coordinates reported by pos-visible-in-window-p for a composed
15214 character in column zero.
15216 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

15220 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15222 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15223 consider it a hit if to_charpos is anywhere in the range of the
15224 composed buffer positions.
15226 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15228 * image.c (gif_load): Don't assume that each subimage has the same
15229 dimensions as the base image. Handle disposal method that is
15230 "undefined" by the gif spec (Bug#9335).
15232 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15234 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
15235 (Fcondition_case): Document `debug' symbol in error handler.
15237 2011-08-19 Eli Zaretskii <eliz@gnu.org>
15239 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15240 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15241 from an Org mode buffer to a Speedbar frame.
15243 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15244 a composition, take its buffer position from IT->cmp_it.charpos.
15245 Fixes cursor positioning at the beginning of a line that begins
15246 with a composed character.
15248 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15250 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15251 character bidirectional type, use STRONG_L instead. Fixes crashes
15252 in a buffer produced by `describe-categories'.
15254 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15255 members before the level stack, so they would be saved and
15256 restored when copying iterator state. Fixes incorrect reordering
15257 around TABs covered by display properties.
15259 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15261 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

15266 (internal_condition_case_2, internal_condition_case_n):
15267 Remove unnecessary aborts (Bug#9081).
15269 2011-08-17 Eli Zaretskii <eliz@gnu.org>
15271 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
15272 has no `load' handler, try opening the file locally. (Bug#9311)
15274 2011-08-16 Ken Brown <kbrown@cornell.edu>
15276 * gmalloc.c: Expand comment.
15278 2011-08-16 Eli Zaretskii <eliz@gnu.org>

15331 * xdisp.c (move_it_in_display_line_to): Don't invoke
15332 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
15333 ppos_it. Fixes vertical cursor motion when line beginning is
15334 covered by an image. (Bug#9296)
15336 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
15338 * nsterm.h (ns_run_ascript): Declare.

15343 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
15344 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
15345 the event loop. Get status from as_status (Bug#7276).
15347 * nsterm.m (sendEvent): If event is NSApplicationDefined and
15348 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
15349 the event loop (Bug#7276).
15351 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
15353 * gnutls.c (QCgnutls_bootprop_priority)

15375 (Fnetwork_interface_list): Allocate in increments of bytes instead
15376 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
15377 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
15379 (struct ifflag_def): notrailers is smart on OSX.
15380 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
15381 Get hardware address with getifaddrs if available.
15383 2011-08-12 Eli Zaretskii <eliz@gnu.org>
15385 * xdisp.c (iterate_out_of_display_property): xassert that
15386 IT->position is set to within IT->object's boundaries. Break from
15387 the loop as soon as EOB is reached; avoids infloops in redisplay
15388 when IT->position is set up wrongly due to some bug.
15389 Set IT->current to match the bidi iterator unconditionally.
15390 (push_display_prop): Allow GET_FROM_STRING as IT->method on
15391 entry. Force push_it to save on the stack the current
15392 buffer/string position, to be restored by pop_it. Fix flags in
15393 the iterator structure wrt the object coming from a display
15394 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
15395 properties. (Bug#9284)
15397 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
15399 * fontset.c (fontset_get_font_group): Add proper type checks.

15431 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
15432 to show the arg `TIME' instead of `TIMEVAL'.
15434 2011-08-06 Eli Zaretskii <eliz@gnu.org>
15436 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
15437 display property strides EOL and includes a newline, as in
15438 longlines-mode. (Bug#9254)
15439 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15440 word-wrap under bidirectional display. (Bug#9224)
15442 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15443 is non-zero, even if the data buffer is NULL. Fixes a crash in
15444 vertical-motion with longlines-mode. (Bug#9254)
15446 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15448 * bidi.c <bidi_cache_total_alloc>: Now static.

15451 * xdisp.c (display_line): Release buffer allocated for shelved bidi
15454 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15455 amount allocated this far in `bidi_cache_total_alloc'.
15456 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15457 non-zero, only free the data buffer without restoring the cache
15458 contents. All callers changed.
15460 * dispextern.h (bidi_unshelve_cache): Update prototype.
15462 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
15463 (move_it_in_display_line, move_it_to)
15464 (move_it_vertically_backward, move_it_by_lines): Replace the call
15465 to xfree to an equivalent call to bidi_unshelve_cache.
15466 (move_it_in_display_line_to): Fix logic of returning
15467 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)

15523 DISP_PROP_P, and pass it to compute_display_string_pos.
15524 Only handle text covered by a display string if DISP_PROP_P is returned
15525 non-zero. All callers of bidi_fetch_char changed.
15527 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>

15613 'malloc' might be invoked reentrantly.
15615 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15616 In other words, assume that every image size is allowed, on non-X
15617 hosts. This assumption is probably wrong, but it lets Emacs compile.

15629 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15631 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15633 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15635 Integer signedness and overflow and related fixes. (Bug#9079)
15637 * bidi.c: Integer size and overflow fixes.
15638 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15639 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15640 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15641 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15642 (bidi_find_other_level_edge):
15643 Use ptrdiff_t instead of EMACS_INT where either will do.
15644 This works better on 32-bit hosts configured --with-wide-int.
15645 (bidi_cache_ensure_space): Check for size-calculation overflow.
15646 Use % rather than repeated addition, for better worst-case speed.
15647 Don't set bidi_cache_size until after xrealloc returns, because it
15649 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15650 (bidi_cache_ensure_space): Also check that the bidi cache size
15651 does not exceed that of the largest Lisp string or buffer. See Eli
15652 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15654 * alloc.c (__malloc_size_t): Remove.
15655 All uses replaced by size_t. See Andreas Schwab's note
15656 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15658 * image.c: Improve checking for integer overflow.
15659 (check_image_size): Assume that f is nonnull, since
15660 it is always nonnull in practice. This is one less thing to
15661 worry about when checking for integer overflow later.
15662 (x_check_image_size): New function, which checks for integer
15663 overflow issues inside X.
15664 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15665 This removes the need for a memory_full check.
15666 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15667 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15668 (xbm_read_bitmap_data): Change locals back to 'int', since
15669 their values must fit in 'int'.
15670 (xpm_load_image, png_load, tiff_load):
15671 Invoke x_create_x_image_and_pixmap earlier,
15672 to avoid much needless work if the image is too large.
15673 (tiff_load): Treat overly large images as if
15674 x_create_x_image_and_pixmap failed, not as malloc failures.
15675 (gs_load): Use x_check_image_size.
15677 * gtkutil.c: Omit integer casts.
15678 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15679 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15681 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15683 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15684 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15685 would wrongly return t on a 64-bit host.
15687 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15688 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15689 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15690 and therefore cause GCC to emit a bogus diagnostic in some cases.
15692 * image.c: Integer signedness and overflow and related fixes.
15693 This is not an exhaustive set of fixes, but it's time to
15694 record what I've got.
15695 (lookup_pixel_color, check_image_size): Remove redundant decls.
15696 (check_image_size): Don't assume that arbitrary EMACS_INT values
15697 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15698 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15699 (tiff_load, imagemagick_load_image):
15700 Check for overflow in size calculations.
15701 (x_create_x_image_and_pixmap): Remove unnecessary test for
15702 xmalloc returning NULL; that can't happen.
15703 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15704 (xpm_color_bucket): Use better integer hashing function.
15705 (xpm_cache_color): Don't possibly over-allocate memory.
15706 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15707 (gif_memory_source):
15708 Use ptrdiff_t, not int or size_t, to record sizes.
15709 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15710 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15711 either works, as we prefer signed integers.
15712 (tiff_read_from_memory, tiff_write_from_memory):
15713 Return tsize_t, not size_t, since that's what the TIFF API wants.
15714 (tiff_read_from_memory): Don't fail simply because the read would
15715 go past EOF; instead, return a short read.
15716 (tiff_load): Omit no-longer-needed casts.
15717 (Fimagemagick_types): Don't assume size fits into 'int'.
15719 Improve hashing quality when configured --with-wide-int.
15720 * fns.c (hash_string): New function, taken from sxhash_string.
15721 Do not discard information about ASCII character case; this
15722 discarding is no longer needed.
15723 (sxhash-string): Use it. Change sig to match it. Caller changed.
15724 * lisp.h: Declare it.
15725 * lread.c (hash_string): Remove, since we now use fns.c's version.
15726 The fns.c version returns a wider integer if --with-wide-int is
15727 specified, so this should help the quality of the hashing a bit.
15729 * emacs.c: Integer overflow minor fix.
15730 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15731 Define only if GNU_LINUX.
15732 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15734 * dispnew.c: Integer signedness and overflow fixes.
15735 Remove unnecessary forward decls, that were a maintenance hassle.
15736 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15738 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15739 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15740 (prepare_desired_row, line_draw_cost):
15741 Use int, not unsigned, where either works.
15742 (save_current_matrix, restore_current_matrix):
15743 Use ptrdiff_t, not size_t, where either works.
15744 (init_display): Check for overflow more accurately, and without
15745 relying on undefined behavior.
15747 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15748 Remove, replacing with the new symbols in lisp.h. All uses changed.
15749 * fileio.c (make_temp_name):
15750 * filelock.c (lock_file_1, lock_file):
15751 * xdisp.c (message_dolog):
15752 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15753 Use pMd etc. instead.
15754 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15755 replacing the pWIDE etc. symbols removed from editfns.c.
15757 * keyboard.h (num_input_events): Now uintmax_t.
15758 This is (very slightly) less likely to mess up due to wraparound.
15761 * buffer.c: Integer signedness fixes.
15762 (alloc_buffer_text, enlarge_buffer_text):
15763 Use ptrdiff_t rather than size_t when either will do, as we prefer
15766 * alloc.c: Integer signedness and overflow fixes.
15767 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15768 (__malloc_size_t): Default to size_t, not to int.
15769 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15770 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15771 Prefer ptrdiff_t to size_t when either would do, as we prefer
15773 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15774 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15775 Now const. Initialize with values that are in range even if char
15777 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15778 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15779 These functions do the right thing with sizes > 2**32.
15780 (check_depth): Now ptrdiff_t, not int.
15781 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15782 Adjust to new way of storing sizes. Check for size overflow bugs
15784 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15785 slightly wrong anyway, as it missed one instance of
15786 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15787 (refill_memory_reserve): Omit needless cast to size_t.
15788 (mark_object_loop_halt): Mark as externally visible.
15790 * xselect.c: Integer signedness and overflow fixes.
15791 (Fx_register_dnd_atom, x_handle_dnd_message):
15792 Use ptrdiff_t, not size_t, since we prefer signed.
15793 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15794 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15795 x_dnd_atoms_size and x_dnd_atoms_length.
15797 * doprnt.c: Prefer signed to unsigned when either works.
15799 * doprnt.c (doprnt):
15801 * xdisp.c (vmessage):
15802 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15803 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15804 prefer signed arithmetic to avoid comparison confusion.
15805 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15806 but is a bit tricky.
15808 Assume freestanding C89 headers, string.h, stdlib.h.
15809 * data.c, doprnt.c, floatfns.c, print.c:
15810 Include float.h unconditionally.
15811 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15812 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15813 * regex.c: Likewise for stddef.h, string.h.
15814 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15815 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15816 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15817 (STDC_HEADERS): Remove obsolete defines.
15818 * sysdep.c: Include limits.h unconditionally.
15820 Assume support for memcmp, memcpy, memmove, memset.
15821 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15822 * regex.c (memcmp, memcpy):
15823 Remove; we assume C89 now.
15825 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15826 (__malloc_safe_bcopy): Remove; no longer needed.
15828 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15829 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15830 well either way, and we prefer signed to unsigned.
15832 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15834 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15835 closes the connection while we're reading (bug#9182).
15837 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15839 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15840 are specified (Bug#9168).
15842 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15844 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15845 Found by GCC static checking and --with-wide-int on a 32-bit host.
15847 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15849 * xdisp.c (compute_display_string_pos): Fix logic of caching
15850 previous display string position. Initialize cached_prev_pos to
15851 -1. Fixes slow-down at the beginning of a buffer.
15853 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15855 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15856 for attrs[LFACE_FONTSET_INDEX].
15858 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15860 * xml.c (parse_region): Remove unused local
15861 that was recently introduced.
15863 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15865 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15866 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15868 * xdisp.c (move_it_in_display_line_to): Record the best matching
15869 position for TO_CHARPOS while scanning the line, and restore it on
15870 exit if none of the characters scanned was an exact match.
15871 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15872 when exact match is impossible due to invisible text, and the
15873 lines are truncated.
15875 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15877 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15880 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15882 Fix a significant slow-down of cursor motion with C-n, C-p,
15883 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15884 auto-repeat under bidi redisplay in fontified buffers.
15885 * xdisp.c (compute_stop_pos_backwards): New function.
15886 (next_element_from_buffer): Call compute_stop_pos_backwards to
15887 find a suitable prev_stop when we find ourselves before
15889 (reseat): Don't look for prev_stop, as that could mean a very long
15891 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15892 <cached_disp_overlay_modiff>: Cache for last found display string
15894 (compute_display_string_pos): Return the cached position if asked
15895 about the same buffer in the same area of character positions, and
15896 the buffer wasn't changed since the time the display string
15897 position was cached.
15899 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15901 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15902 is an integer, which is important for empty lines. (Bug#9149)
15904 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15906 * frame.c (Fmodify_frame_parameters): In tty case, update the
15907 default face if necessary (Bug#4238).
15909 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15911 * editfns.c (Fstring_to_char): No need to explain what a character
15912 is in the docstring (Bug#6576).
15914 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15916 * xml.c (parse_region): Make sure we always return a tree.
15918 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15920 * xml.c (parse_region): If a document contains only comments,
15923 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15925 * xml.c (make_dom): Return comments, too.
15927 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15930 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15931 and the surrounding thread.
15932 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15933 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15934 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15936 * s/openbsd.h (BROKEN_SIGIO): Define.
15937 * unexelf.c (unexec) [__OpenBSD__]:
15938 Don't update the .mdebug section of the Alpha COFF symbol table.
15940 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15942 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15945 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15947 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15948 This fixes some race conditions on the permissions of any newly
15951 * alloc.c (valid_pointer_p): Use pipe, not open.
15952 This fixes some permissions issues when debugging.
15954 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15955 If fchown fails to set both uid and gid, try to set just gid,
15956 as that is sometimes allowed. Adjust the file's mode to eliminate
15957 setuid or setgid bits that are inappropriate if fchown fails.
15959 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15961 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15962 to compare Lisp_Objects.
15963 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15964 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15965 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15967 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15969 * lread.c (read_integer): Unread even EOF character.
15970 (read1): Likewise. Properly record start position of symbol.
15972 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15973 symbol character follows.
15975 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15977 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15978 This works around a problem with the previous change to Fcopy_file.
15979 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15980 and without this change, GCC might complain about discarding
15981 fchown's return value.
15983 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15985 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15987 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15989 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15991 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15993 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15994 it's used from the C level.
15996 * process.c: Use the same condition for POLL_FOR_INPUT in both
15997 keyboard.c and process.c (bug#1858).
15999 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16001 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16002 (Fgnutls_boot): Use it.
16004 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16006 * doc.c (Fsubstitute_command_keys): Revert last change.
16008 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16010 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16011 quotes the next character, and doesn't affect other longer
16012 sequences (bug#8935).
16014 * lread.c (syms_of_lread): Clarify that is isn't only
16015 `eval-buffer' and `eval-defun' that's affected by
16016 `lexical-binding' (bug#8460).
16018 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16020 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16021 bidi redisplay when a line includes both an image and is truncated.
16023 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16025 Fix minor problems found by static checking.
16026 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16027 (elsz): Now a signed constant, not a size_t var. We prefer signed
16028 types to unsigned, to avoid integer comparison confusion. Without
16029 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16030 "cannot optimize loop, the loop counter may overflow", a symptom
16032 * indent.c (Fvertical_motion): Mark locals as initialized.
16033 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16035 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16037 * search.c (Fre_search_backward): Mention `case-fold-search' in
16038 all the re_search_* functions (bug#8138).
16040 * keyboard.c (Fopen_dribble_file): Document when the file is
16043 2011-07-14 Eli Zaretskii <eliz@gnu.org>
16045 * bidi.c (bidi_dump_cached_states): Fix format of displaying
16048 Support bidi reordering of display and overlay strings.
16049 * xdisp.c (compute_display_string_pos)
16050 (compute_display_string_end): Accept additional argument STRING.
16051 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
16052 (reseat_to_string): Initialize bidi_it->string.s and
16053 bidi_it->string.schars.
16054 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
16055 NULL (avoids a crash in bidi_paragraph_init).
16056 Initialize itb.string.lstring.
16057 (init_iterator): Call bidi_init_it only of a valid
16058 buffer position was specified. Initialize paragraph_embedding to
16060 (reseat_to_string): Initialize the bidi iterator.
16061 (display_string): If we need to ignore text properties of
16062 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16063 original value of -1 will not work with bidi.)
16064 (compute_display_string_pos): First arg is now struct
16065 `text_pos *'; all callers changed. Support display properties on
16067 (compute_display_string_end): Support display properties on Lisp
16069 (init_iterator, reseat_1, reseat_to_string): Initialize the

16557 (clone_per_buffer_values): Don't assume that

16559 This isn't true in general, and it's particularly not true
16560 if Emacs is configured with --with-wide-int.
16561 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16562 New macros, used in the buffer.c change.

16598 Random fixes. E.g., (random) never returned negative values.
16599 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16600 subseconds part to the entropy, as that's a bit more random.
16601 Prefer signed to unsigned, since the signedness doesn't matter and
16602 in general we prefer signed. When given a limit, use a
16603 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16604 latter isn't right if USE_2_TAGS_FOR_INTS.
16605 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16606 not 0..VALMASK. Don't discard "excess" bits that random () returns.
16608 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
16610 * textprop.c (text_property_stickiness):
16611 Obey Vtext_property_default_nonsticky.

16618 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16619 This is more efficient than Ffile_directory_p and avoids a minor race.
16621 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16623 * buffer.c (Foverlay_put): Say what the return value is
16626 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16627 is a directory before asking whether to use the file name
16629 (barf_or_query_if_file_exists): Make the "File is a directory"
16630 error be more correct.
16632 * fns.c (Frequire): Remove the mention of the .gz files, since
16633 that's installation-specific, but keep the mention of
16634 `get-load-suffixes'.

16646 Qgnutls_bootprop_verify_error (which is no longer used).
16648 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16649 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16650 Also (re)move comments that are misplaced or no longer relevant.
16652 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16654 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

16713 (syms_of_keymap): Defsubr make-composed-keymap.
16714 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

16751 * eval.c (struct backtrace): Simplify and port the data structure.
16752 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16753 signed bit field, as this assumption is not portable and it makes
16754 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16755 "char debug_on_exit : 1" as this is not portable either; instead,
16756 use the portable "unsigned int debug_on_exit : 1". Remove unused
16757 member evalargs. Remove obsolete comments about cc bombing out.
16759 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16945 to improve quality of diagnostics for out-of-range radices.
16946 Calculate buffer size correctly for out-of-range radices.
16947 (read1): Check for integer overflow in radices, and in
16948 read-circle numbers.
16949 (read_escape): Avoid int overflow.
16950 (Fload, openp, read_buffer_size, read1)
16951 (substitute_object_recurse, read_vector, read_list, map_obarray):
16952 Use ptrdiff_t, not int, for sizes.
16953 (read1): Use EMACS_INT, not int, for sizes.
16954 Check for size overflow.
16956 * image.c (cache_image): Check for size arithmetic overflow.
16958 * lread.c: Integer overflow issues.
16959 (saved_doc_string_size, saved_doc_string_length)

16961 Now ptrdiff_t, not int.
16962 (read1): Don't assume doc string length fits in int. Check for
16963 out-of-range doc string lengths.
16964 (read_list): Don't assume file position fits in int.
16965 (read_escape): Check for hex character overflow.
16967 2011-06-22 Leo Liu <sdl.web@gmail.com>
16969 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16970 Move to minibuffer.el.
16972 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16974 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16975 The following patches are for when GLYPH_DEBUG && !XASSERT.
16976 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16977 * dispnew.c (flush_stdout):
16978 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16979 Mark as externally visible.
16980 * dispnew.c (check_window_matrix_pointers): Now static.
16981 * dispnew.c (window_to_frame_vpos):
16982 * xfns.c (unwind_create_frame):
16983 * xterm.c (x_check_font): Remove unused local.
16984 * scroll.c (CHECK_BOUNDS):
16985 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16986 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16987 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16988 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16989 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16991 (debug_method_add): Use va_list and vsprintf rather than relying
16992 on undefined behavior with wrong number of arguments.
16993 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16994 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16995 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16996 since we're not interested in debugging glyphs with old libraries.
16997 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16998 GCC 4.6.0's static checking.
17000 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
17002 Integer overflow and signedness fixes (Bug#8873).

17016 * xfaces.c (load_pixmap):
17017 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
17018 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
17019 (.bitmaps_last, struct x_output.icon_bitmap):
17020 Use ptrdiff_t, not int, for bitmap indexes.
17021 (x_allocate_bitmap_record): Check for size overflow.
17022 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
17024 Use ptrdiff_t, not int, for overlay counts.
17025 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
17026 * editfns.c (overlays_around, get_pos_property):
17027 * textprop.c (get_char_property_and_overlay):
17028 * xdisp.c (next_overlay_change, note_mouse_highlight):
17029 * xfaces.c (face_at_buffer_position):
17030 * buffer.c (OVERLAY_COUNT_MAX): New macro.
17031 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
17032 (Fnext_overlay_change, Fprevious_overlay_change)
17033 (mouse_face_overlay_overlaps, Foverlays_in):
17034 Use ptrdiff_t, not int, for sizes.
17035 (overlays_at, overlays_in): Check for size-calculation overflow.
17037 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17039 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17040 (x_session_initialize): Do not assume string length fits in int.
17042 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17043 This is unlikely, but can occur if DPI is outlandish.
17045 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17046 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17048 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17049 * xrdb.c (magic_file_p, search_magic_path):
17050 Omit last arg SUFFIX; it was always 0. All callers changed.
17051 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17053 * xfont.c (xfont_match): Avoid need for strlen.
17055 * xfns.c: Don't assume strlen fits in int.

17058 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17059 not unsigned long, as we prefer signed integers. All callers changed.
17060 Detect integer overflow in repeat count.
17061 (message_dolog): Don't assume print length fits in 39 bytes.
17062 (display_mode_element): Don't assume strlen fits in int.
17064 * termcap.c: Don't assume sizes fit in int and never overflow.
17065 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17066 (gobble_line): Check for size-calculation overflow.
17068 * minibuf.c (Fread_buffer):
17069 * lread.c (intern, intern_c_string):
17070 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17071 Don't assume string length fits in int.
17073 * keyboard.c (parse_tool_bar_item):
17074 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17076 * font.c: Don't assume string length fits in int.
17077 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17078 Use ptrdiff_t, not int.
17079 (font_intern_prop): Don't assume string length fits in int.
17080 Don't assume integer property fits in fixnum.
17081 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17083 * filelock.c: Fix some buffer overrun and integer overflow issues.
17084 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17085 Reformulate so as not to need the command string.
17086 Invoke gzip -cd rather than gunzip, as it's more portable.
17087 (lock_info_type, lock_file_1, lock_file):
17088 Don't assume pid_t and time_t fit in unsigned long.
17089 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17090 (current_lock_owner): Prefer signed type for sizes.
17091 Use memcpy, not strncpy, where memcpy is what is really wanted.
17092 Don't assume (via atoi) that time_t and pid_t fit in int.
17093 Check for time_t and/or pid_t out of range, e.g., via a network share.
17094 Don't alloca where an auto var works fine.
17096 * fileio.c: Fix some integer overflow issues.
17097 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17098 Don't assume string length fits in int.
17099 (directory_file_name): Don't assume string length fits in long.
17100 (make_temp_name): Don't assume pid fits in int, or that its print
17101 length is less than 20.
17103 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17105 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17107 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17109 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17110 We prefer signed integers, even for size calculations.
17112 * emacs.c: Don't assume string length fits in 'int'.
17113 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17114 (main): Don't invoke strlen when not needed.
17116 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17117 (XD_DEBUG_MESSAGE): Don't waste a byte.
17119 * callproc.c (getenv_internal_1, getenv_internal)
17120 (Fgetenv_internal):
17121 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17123 * lread.c (invalid_syntax): Omit length argument.
17124 All uses changed. This doesn't fix a bug, but it simplifies the
17125 code away from its former Hollerith-constant appearance, and it's
17126 one less 'int' to worry about when looking at integer-overflow issues.
17127 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17129 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17130 This didn't break anything, but it didn't help either.
17131 It's confusing to put a bogus integer in a place where the actual
17132 value does not matter.
17133 (LIST_END_P): Remove unused macro and its bogus comment.
17134 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17136 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17137 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17139 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17140 We prefer signed types, and the value cannot exceed the EMACS_INT
17141 range anyway (because otherwise the length would not be representable).
17142 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17143 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17144 This avoids a GCC warning when WIDE_EMACS_INT.
17146 * indent.c (sane_tab_width): New function.
17147 (current_column, scan_for_column, Findent_to, position_indentation)
17148 (compute_motion): Use it. This is just for clarity.
17149 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17151 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17153 * lisp.h (lint_assume): New macro.
17154 * composite.c (composition_gstring_put_cache):
17155 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17157 * editfns.c, insdel.c:
17158 Omit unnecessary forward decls, to simplify future changes.
17160 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17162 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17164 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17165 Use much-faster test for byte-length change.
17166 Don't assume string byte-length fits in 'int'.
17167 Check that character arg fits in 'int'.
17168 (mapcar1): Declare byte as byte, for clarity.
17170 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17172 * fns.c (concat): Catch string overflow earlier.
17173 Do not rely on integer wraparound.
17175 * dispextern.h (struct it.overlay_strings_charpos)
17176 (struct it.selective): Now EMACS_INT, not int.
17177 * xdisp.c (forward_to_next_line_start)
17178 (back_to_previous_visible_line_start)
17179 (reseat_at_next_visible_line_start, next_element_from_buffer):
17180 Don't arbitrarily truncate the value of 'selective' to int.
17182 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17184 * composite.c: Don't truncate sizes to 'int'.
17185 (composition_gstring_p, composition_reseat_it)
17186 (composition_adjust_point): Use EMACS_INT, not int.
17187 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17188 not EMACS_UINT, for indexes.
17190 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17192 * buffer.c: Include <verify.h>.
17193 (struct sortvec.priority, struct sortstr.priority):
17194 Now EMACS_INT, not int.
17195 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17196 (struct sortstr.size, record_overlay_string)
17197 (struct sortstrlist.size, struct sortlist.used):
17198 Don't truncate size to int.
17199 (record_overlay_string): Check for size-calculation overflow.
17200 (init_buffer_once): Check at compile-time, not run-time.
17202 2011-06-22 Jim Meyering <meyering@redhat.com>
17204 Don't leak an XBM-image-sized buffer
17205 * image.c (xbm_load): Free the image buffer after using it.
17207 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17210 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17211 that Sun C diagnosed.
17212 * fns.c (secure_hash): Fix pointer signedness issue.
17213 * intervals.c (static_offset_intervals): New function.
17214 (offset_intervals): Use it.
17216 2011-06-21 Leo Liu <sdl.web@gmail.com>
17219 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17222 * fns.c (secure_hash): Rename from crypto_hash_function and change
17223 the first arg to accept symbols.
17224 (Fsecure_hash): New primitive.
17225 (syms_of_fns): New symbols.
17227 2011-06-20 Deniz Dogan <deniz@dogan.se>
17229 * process.c (Fset_process_buffer): Clarify return value in
17232 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17234 * dispnew.c (add_window_display_history): Use BVAR.
17236 * xdisp.c (debug_method_add): Use BVAR.
17237 (check_window_end, dump_glyph_matrix, dump_glyph)
17238 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17240 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17243 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17244 check till after the cache is created in init_frame_faces.
17246 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17248 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17250 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17252 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17253 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17254 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17256 Improve buffer-overflow checking (Bug#8873).
17257 * fileio.c (Finsert_file_contents):
17258 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17259 Remove the old (too-loose) buffer overflow checks.
17260 They weren't needed, since make_gap checks for buffer overflow.
17261 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17262 The old code merely checked for Emacs fixnum overflow, and relied
17263 on undefined (wraparound) behavior. The new code avoids undefined
17264 behavior, and also checks for ptrdiff_t and/or size_t overflow.
17266 * editfns.c (Finsert_char): Don't dump core with very negative counts.
17267 Tune. Don't use wider integers than needed. Don't use alloca.
17268 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
17270 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
17272 * insdel.c, lisp.h (buffer_overflow): New function.
17273 (insert_from_buffer_1, replace_range, replace_range_2):
17274 * insdel.c (make_gap_larger):
17275 * editfns.c (Finsert_char):
17276 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
17278 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
17280 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
17282 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
17284 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
17285 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
17287 * fileio.c: Don't assume EMACS_INT fits in off_t.
17288 (emacs_lseek): New static function.
17289 (Finsert_file_contents, Fwrite_region): Use it.
17290 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
17292 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
17294 * fns.c: Don't overflow int when computing a list length.
17295 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
17296 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
17297 truncation on 64-bit hosts. Check for QUIT every
17298 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
17299 faster and is responsive enough.
17300 (Flength): Report an error instead of overflowing an integer.
17301 (Fsafe_length): Return a float if the value is not representable
17302 as a fixnum. This shouldn't happen except in contrived situations.
17303 (Fnthcdr, Fsort): Don't assume list length fits in int.
17304 (Fcopy_sequence): Don't assume vector length fits in int.
17306 * alloc.c: Check that resized vectors' lengths fit in fixnums.
17307 (header_size, word_size): New constants.
17308 (allocate_vectorlike): Don't check size overflow here.
17309 (allocate_vector): Check it here instead, since this is the only
17310 caller of allocate_vectorlike that could cause overflow.
17311 Check that the new vector's length is representable as a fixnum.
17313 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
17314 The previous code was bogus. For example, next_almost_prime (32)
17315 returned 39, which is undesirable as it is a multiple of 3; and
17316 next_almost_prime (24) returned 25, which is a multiple of 5 so
17317 why was the code bothering to check for multiples of 7?
17319 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
17321 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
17323 Variadic C functions now count arguments with ptrdiff_t.
17324 This partly undoes my 2011-03-30 change, which replaced int with size_t.
17325 Back then I didn't know that the Emacs coding style prefers signed int.
17326 Also, in the meantime I found a few more instances where arguments
17327 were being counted with int, which may truncate counts on 64-bit
17328 machines, or EMACS_INT, which may be unnecessarily wide.
17329 * lisp.h (struct Lisp_Subr.function.aMANY)
17330 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
17331 Arg counts are now ptrdiff_t, not size_t.
17332 All variadic functions and their callers changed accordingly.
17333 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
17334 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
17335 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
17336 * callint.c (Fcall_interactively): Check arg count for overflow,
17337 to avoid potential buffer overrun. Use signed char, not 'int',
17338 for 'varies' array, so that we needn't bother to check its size
17339 calculation for overflow.
17340 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
17341 * eval.c (apply_lambda):
17342 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
17343 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
17344 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
17346 * callint.c (Fcall_interactively): Don't use index var as event count.
17348 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
17349 * mem-limits.h (SIZE): Remove; no longer used.
17351 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
17353 Remove unnecessary casts.
17354 * xterm.c (x_term_init):
17355 * xfns.c (x_set_border_pixel):
17356 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
17357 These aren't needed now that we assume ANSI C.
17359 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
17360 It's more likely to cause problems (due to unsigned overflow)
17363 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
17365 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
17367 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
17369 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
17371 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
17373 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
17375 GLYPH_CODE_FACE returns EMACS_INT, not int.
17376 * dispextern.h (merge_faces):
17377 * xfaces.c (merge_faces):
17378 * xdisp.c (get_next_display_element, next_element_from_display_vector):
17379 Don't assume EMACS_INT fits in int.
17381 * character.h (CHAR_VALID_P): Remove unused parameter.
17382 * fontset.c, lisp.h, xdisp.c: All uses changed.
17384 * editfns.c (Ftranslate_region_internal): Omit redundant test.
17386 * fns.c (concat): Minor tuning based on overflow analysis.
17387 This doesn't fix any bugs. Use int to hold character, instead
17388 of constantly refetching from Emacs object. Use XFASTINT, not
17389 XINT, for value known to be a character. Don't bother comparing
17390 a single byte to 0400, as it's always less.
17392 * floatfns.c (Fexpt):
17393 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
17395 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17398 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17400 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17401 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17402 incorrectly succeed when S was a string, because 4294967386 was
17403 truncated before it was used.
17405 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17406 Otherwise, an out-of-range integer could cause undefined behavior
17409 * composite.c: Use int, not EMACS_INT, for characters.
17410 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17411 EMACS_INT, for values that are known to be in character range.
17412 This doesn't fix any bugs but is the usual style inside Emacs and
17413 may generate better code on 32-bit machines.
17415 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17416 This is for reasons similar to the recent CHAR_STRING fix.
17417 * charset.c (Fencode_char): Check that character arg is actually
17418 a character. Pass an int to ENCODE_CHAR.
17419 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17420 wider than 'int', as a compile-time check to prevent future regressions
17423 * character.c (char_string): Remove unnecessary casts.
17425 Make sure a 64-bit char is never passed to CHAR_STRING.
17426 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17427 by silently ignoring the top 32 bits, allowing some values
17428 that were far too large to be valid characters.
17429 * character.h: Include <verify.h>.
17430 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17431 arguments are no wider than unsigned, as a compile-time check
17432 to prevent future regressions in this area.
17434 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17435 (Fsubst_char_in_region):
17437 * xdisp.c (decode_mode_spec_coding):
17438 Adjust to CHAR_STRING's new requirement.
17439 * editfns.c (Finsert_char, Fsubst_char_in_region):
17440 * fns.c (concat): Check that character args are actually
17441 characters. Without this test, these functions did the wrong
17442 thing with wildly out-of-range values on 64-bit hosts.
17444 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17445 These casts should not be needed on 32-bit hosts, either.
17446 * keyboard.c (read_char):
17447 * lread.c (Fload): Remove casts to unsigned.
17449 * lisp.h (UNSIGNED_CMP): New macro.
17450 This fixes comparison bugs on 64-bit hosts.
17451 (ASCII_CHAR_P): Use it.
17452 * casefiddle.c (casify_object):
17453 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17454 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17455 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17456 * dispextern.h (FACE_FROM_ID):
17457 * keyboard.c (read_char): Use UNSIGNED_CMP.
17459 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17460 not to EMACS_INT, to avoid GCC warning.
17462 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17464 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17465 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17466 isn't needed on 32-bit machines.
17468 * buffer.c (Fgenerate_new_buffer_name):
17469 Use EMACS_INT for count, not int.
17470 (advance_to_char_boundary): Return EMACS_INT, not int.
17472 * data.c (Qcompiled_function): Now static.
17474 * window.c (window_body_lines): Now static.
17476 * image.c (gif_load): Rename local to avoid shadowing.
17478 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17479 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17480 * alloc.c (make_save_value): Integer argument is now of type
17481 ptrdiff_t, not int.
17482 (mark_object): Use ptrdiff_t, not int.
17483 * lisp.h (pD): New macro.
17484 * print.c (print_object): Use it.
17486 * alloc.c: Use EMACS_INT, not int, to count objects.
17487 (total_conses, total_markers, total_symbols, total_vector_size)
17488 (total_free_conses, total_free_markers, total_free_symbols)
17489 (total_free_floats, total_floats, total_free_intervals)
17490 (total_intervals, total_strings, total_free_strings):
17491 Now EMACS_INT, not int. All uses changed.
17492 (Fgarbage_collect): Compute overall total using a double, so that
17493 integer overflow is less likely to be a problem. Check for overflow
17494 when converting back to an integer.
17495 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17496 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17497 These were 'int' variables that could overflow on 64-bit hosts;
17498 they were never used, so remove them instead of repairing them.
17499 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17500 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17501 Previously, this ceilinged at INT_MAX, but that doesn't work on
17503 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17505 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17506 (allocate_vectorlike): Check for ptrdiff_t overflow.
17507 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17508 when a (possibly-narrower) signed value would do just as well.
17509 We prefer using signed arithmetic, to avoid comparison confusion.
17511 * alloc.c: Catch some string size overflows that we were missing.
17512 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17513 for convenience in STRING_BYTES_MAX.
17514 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17515 The definition here is exact; the one in lisp.h was approximate.
17516 (allocate_string_data): Check for string overflow. This catches
17517 some instances we weren't catching before. Also, it catches
17518 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17519 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17520 and ptrdiff_t and EMACS_INT are both 64 bits.
17522 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17523 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17524 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17526 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17528 * alloc.c (Fmake_string): Check for out-of-range init.
17530 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17532 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17534 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17536 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

17539 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17540 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17541 (style_changed_cb): Call update_theme_scrollbar_width and call
17542 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17543 all frames (Bug#8505).
17544 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
17545 Call gtk_window_set_resizable if HAVE_GTK3.

17547 and height if HAVE_GTK3 (Bug#8505).
17548 (scroll_bar_width_for_theme): New variable.
17549 (update_theme_scrollbar_width): New function.
17550 (xg_get_default_scrollbar_width): Move code to
17551 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

17554 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17556 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17558 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17560 * frame.c (make_frame): Call other_buffer_safely instead of
17563 * window.c (temp_output_buffer_show): Call display_buffer with
17564 second argument Vtemp_buffer_show_specifiers and reset latter
17565 immediately after the call.
17566 (Vtemp_buffer_show_specifiers): New variable.
17567 (auto_window_vscroll_p, next_screen_context_lines)
17568 (Vscroll_preserve_screen_position): Remove leading asterisks from

18101 instead of using explicit *_CHAR codes.
18102 (bidi_resolve_explicit, bidi_resolve_weak):

18119 (display_prop_intangible_p): Reimplement to call
18120 handle_display_spec instead of single_display_spec_intangible_p.
18121 Accept 3 additional arguments needed by handle_display_spec.

18132 value of a `display' property is a "replacing spec".
18133 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18134 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

18162 All callers changed. (Bug#8762)
18164 * gnutls.c: Use Emacs's memory allocators.
18165 Without this change, the gnutls library would invoke malloc etc.
18166 directly, which causes problems on non-SYNC_INPUT hosts, and which
18167 runs afoul of improving memory_full behavior. (Bug#8761)
18168 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18169 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18170 xfree instead of the default malloc, realloc, free.
18171 (Fgnutls_boot): No need to check for memory allocation failure,
18172 since xmalloc does that for us.
18174 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

18195 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18196 * alloc.c (allocate_vectorlike):
18197 Check for overflow in vector size calculations.
18198 * ccl.c (ccl_driver):
18199 Check for overflow when converting EMACS_INT to int.

18201 need to be updated by these changes.
18202 * fns.c (make_hash_table, maybe_resize_hash_table):
18203 Check for integer overflow with large hash tables.
18204 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18205 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18206 (SXHASH_REDUCE): New macro.
18207 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18208 Use it instead of discarding useful hash info with large hash values.
18209 (sxhash_float): New function.
18210 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18211 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18212 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18213 Rewrite to use FIXNUM_BITS, as this simplifies things.
18214 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18215 Adjust signatures to match updated version of code.
18216 (consing_since_gc): Now EMACS_INT, since a single hash table can
18217 use more than INT_MAX bytes.

18245 only when CANNOT_DUMP is defined.
18246 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18248 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18250 * dispnew.c (add_window_display_history): Use const for the string
18251 pointer. Remove declaration, not needed.
18253 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18255 Use 'inline', not 'INLINE'.
18256 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18257 * alloc.c, fontset.c (INLINE): Remove.
18258 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18259 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18260 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18261 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18262 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18264 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18266 Make it possible to run ./temacs.
18268 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
18269 syms_of_callproc does the same thing. Remove test for
18270 "initialized", do it in the caller.
18271 * emacs.c (main): Avoid calling set_initial_environment when dumping.
18273 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
18275 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
18276 (read_minibuf): Use get_minibuffer.
18277 (syms_of_minibuf): Use DEFSYM.
18278 (Qmetadata): New var.
18279 * data.c (Qbuffer): Don't make it static.
18280 (syms_of_data): Use DEFSYM.
18282 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18284 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
18285 (CCL_CODE_MIN): New macro.
18287 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
18289 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
18291 * eval.c (Qdebug): Now static.
18292 * lisp.h (Qdebug): Remove decl. This reverts a part of the
18293 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
18294 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
18296 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18298 * image.c: Various fixes to ImageMagick code comments.
18299 (Fimagemagick_types): Doc fix.
18301 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
18303 Minor fixes prompted by GCC 4.6.0 warnings.
18305 * xselect.c (converted_selections, conversion_fail_tag): Now static.
18307 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
18308 (x_clipboard_manager_save_all): Move extern decl to ...
18309 * xterm.h: ... here, so that it can be checked for consistency.
18311 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
18313 * xselect.c (x_clipboard_manager_save_frame)
18314 (x_clipboard_manager_save_all): New functions.
18315 (Fx_clipboard_manager_save): Lisp function deleted.
18317 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
18318 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
18320 * xterm.h: Update prototype.
18322 2011-05-28 William Xu <william.xwl@gmail.com>
18324 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
18325 exiting (Bug#8239).
18327 2011-05-28 Jim Meyering <meyering@redhat.com>
18329 Avoid a sign-extension bug in crypto_hash_function.
18330 * fns.c (to_uchar): Define.
18331 (crypto_hash_function): Use it to convert some newly-signed
18332 variables to unsigned, to avoid sign-extension bugs. For example,
18333 without this change, (md5 "truc") would evaluate to
18334 45723a2aff78ff4fff7fff1114760e62 rather than the expected
18335 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
18336 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
18338 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18340 Integer overflow fixes.
18342 * dbusbind.c: Serial number integer overflow fixes.
18343 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
18344 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
18345 to hold a serial number that is too large for a fixnum.
18346 (Fdbus_method_return_internal, Fdbus_method_error_internal):
18347 Check for serial numbers out of range. Decode any serial number
18348 that was so large that it became a float. (Bug#8722)
18350 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
18351 (Fdbus_call_method, Fdbus_call_method_asynchronously):
18352 Use XFASTINT rather than XUINT when numbers are nonnegative.
18353 (xd_append_arg, Fdbus_method_return_internal):
18354 (Fdbus_method_error_internal): Likewise. Also, for unsigned
18355 arguments, check that Lisp number is nonnegative, rather than
18356 silently wrapping negative numbers around. (Bug#8722)
18357 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
18360 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
18362 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
18364 ccl: Add integer overflow checks.
18365 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
18366 (IN_INT_RANGE): New macros.
18367 (ccl_driver): Use them to check for integer overflow when
18368 decoding a CCL program. Many of the new checks are whether XINT (x)
18369 fits in int; it doesn't always, on 64-bit hosts. The new version
18370 doesn't catch all possible integer overflows, but it's an
18371 improvement. (Bug#8719)
18373 * alloc.c (make_event_array): Use XINT, not XUINT.
18374 There's no need for unsigned here.
18376 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
18377 This follows up to the 2011-05-06 change that substituted uintptr_t
18378 for EMACS_INT. This case wasn't caught back then.
18380 Rework Fformat to avoid integer overflow issues.
18381 * editfns.c: Include <float.h> unconditionally, as it's everywhere
18382 now (part of C89). Include <verify.h>.
18383 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
18384 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
18385 (Fformat): Avoid the prepass trying to compute sizes; it was only
18386 approximate and thus did not catch overflow reliably. Instead, walk
18387 through the format just once, formatting and computing sizes as we go,
18388 checking for integer overflow at every step, and allocating a larger
18389 buffer as needed. Keep track separately whether the format is
18390 multibyte. Keep only the most-recently calculated precision, rather
18391 than them all. Record whether each argument has been converted to
18392 string. Use EMACS_INT, not int, for byte and char and arg counts.
18393 Support field widths and precisions larger than INT_MAX. Avoid
18394 sprintf's undefined behavior with conversion specifications such as %#d
18395 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18396 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18397 formatting out-of-range floating point numbers with int
18398 formats. (Bug#8668)
18400 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18402 * data.c: Avoid integer truncation in expressions involving floats.
18403 * data.c: Include <intprops.h>.
18404 (arith_driver): When there's an integer overflow in an expression
18405 involving floating point, convert the integers to floating point
18406 so that the resulting value does not suffer from catastrophic
18407 integer truncation. For example, on a 64-bit host (* 4
18408 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18409 Do not rely on undefined behavior after integer overflow.
18411 merge count_size_as_multibyte, parse_str_to_multibyte
18412 * character.c, character.h (count_size_as_multibyte):
18413 Rename from parse_str_to_multibyte; all uses changed.
18414 Check for integer overflow.
18415 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18416 since it's now a duplicate of the other. This is more of
18417 a character than a buffer op, so better that it's in character.c.
18418 * fns.c, print.c: Adjust to above changes.
18420 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18422 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18424 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18426 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18427 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18428 (x_clipboard_manager_save): Now static.
18429 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18431 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18432 (crypto_hash_function): Now static.
18433 Fix pointer signedness problems. Avoid unnecessary initializations.
18435 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18437 * termhooks.h (Vselection_alist): Make it terminal-local.
18439 * terminal.c (create_terminal): Initialize it.
18441 * xselect.c: Support for clipboard managers.
18442 (Vselection_alist): Move to termhooks.h as terminal-local var.
18443 (LOCAL_SELECTION): New macro.
18444 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18445 (symbol_to_x_atom): Remove gratuitous arg.
18446 (x_handle_selection_request, lisp_data_to_selection_data)
18447 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18448 (x_own_selection, x_get_local_selection, x_convert_selection):
18449 New arg, specifying work frame. Use terminal-local Vselection_alist.
18450 (some_frame_on_display): Delete unused function.
18451 (Fx_own_selection_internal, Fx_get_selection_internal)
18452 (Fx_disown_selection_internal, Fx_selection_owner_p)
18453 (Fx_selection_exists_p): New optional frame arg.
18454 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18455 (x_handle_selection_clear): Don't treat other terminals with the
18456 same keyboard specially. Use the terminal-local Vselection_alist.
18457 (x_clear_frame_selections): Use Frun_hook_with_args.
18459 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18461 * xterm.h: Add support for those atoms.
18463 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18465 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18466 (converted_selections, conversion_fail_tag): New global variables.
18467 (x_selection_request_lisp_error): Free the above.
18468 (x_get_local_selection): Remove unnecessary code.
18469 (x_reply_selection_request): Args changed; handle arbitrary array
18470 of converted selections stored in converted_selections.
18471 Separate the XChangeProperty and SelectionNotify steps.
18472 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18473 (x_convert_selection): New function.
18474 (x_handle_selection_event): Simplify.
18475 (x_get_foreign_selection): Don't ignore incoming requests while
18476 waiting for an answer; this will fail when we implement
18477 SAVE_TARGETS, and seems unnecessary anyway.
18478 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18479 (Vx_sent_selection_functions): Doc fix.
18481 2011-05-26 Leo Liu <sdl.web@gmail.com>
18483 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18485 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18487 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18489 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18490 for fringe update if it has periodic bitmap.
18491 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18492 and fringe_bitmap_periodic_p.
18494 * fringe.c (get_fringe_bitmap_data): New function.
18495 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18496 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18497 row. Mark glyph row for fringe update if periodicity changed.
18499 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18500 for fringe update unless it has periodic bitmap.
18502 2011-05-25 Kenichi Handa <handa@m17n.org>
18504 * xdisp.c (get_next_display_element): Set correct it->face_id for
18505 a static composition.
18507 2011-05-24 Leo Liu <sdl.web@gmail.com>
18510 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18512 * fns.c (crypto_hash_function, Fsha1): New function.
18513 (Fmd5): Use crypto_hash_function.
18514 (syms_of_fns): Add Ssha1.
18516 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18518 * gnutls.c: Remove unused macros.
18519 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18520 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18521 Remove macros that are defined and never used.
18522 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18524 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18526 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18527 (Fx_get_selection_internal): Minor cleanup.
18528 (Fx_own_selection_internal): Rename arguments for consistency with
18531 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18533 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18535 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18537 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18539 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18541 * dispnew.c (scrolling_window): Don't exclude the case that the
18542 last enabled row in the desired matrix touches the bottom boundary.
18544 2011-05-21 Glenn Morris <rgm@gnu.org>
18546 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18547 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18548 and add some more files.
18550 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18552 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18553 report_file_error introduced by the change from 2011-05-07.
18555 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18557 * systime.h (Time): Define only if emacs is defined.
18558 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18559 where the include path doesn't have X11/X.h by default. See
18560 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18562 2011-05-20 Kenichi Handa <handa@m17n.org>
18564 * composite.c (find_automatic_composition): Fix previous change.
18566 2011-05-20 Glenn Morris <rgm@gnu.org>
18568 * lisp.mk: New file, split from Makefile.in.
18569 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18570 (shortlisp): Remove.
18571 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18573 2011-05-19 Glenn Morris <rgm@gnu.org>
18575 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18576 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18577 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18578 (lisp): Set the order to that of loadup.el.
18579 (shortlisp): Make it a copy of $lisp.
18580 (SOME_MACHINE_LISP): Remove.
18581 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18582 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18584 2011-05-18 Kenichi Handa <handa@m17n.org>
18586 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18587 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18588 (find_automatic_composition): Mostly rewrite for efficiency.
18590 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18592 * makefile.w32-in: Update dependencies.
18594 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18596 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18597 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18599 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18601 Fix some integer overflow issues, such as string length overflow.
18603 * insdel.c (count_size_as_multibyte): Check for string overflow.
18605 * character.c (lisp_string_width): Check for string overflow.
18606 Use EMACS_INT, not int, for string indexes and lengths; in
18607 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18608 the resulting string length overflows an EMACS_INT; instead,
18609 report a string overflow if no precision given. When checking for
18610 precision exhaustion, use a check that cannot possibly have
18611 integer overflow. (Bug#8675)
18612 * character.h (lisp_string_width): Adjust to new signature.
18614 * alloc.c (string_overflow): New function.
18615 (Fmake_string): Use it. This doesn't change behavior, but saves
18616 a few bytes and will simplify future changes.
18617 * character.c (string_escape_byte8): Likewise.
18618 * lisp.h (string_overflow): New decl.
18620 Fixups, following up to the user-interface timestamp change.
18621 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18622 for UI timestamps, instead of unsigned long.
18623 * msdos.c (mouse_get_pos): Likewise.
18624 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18625 * w32gui.h (Time): Define by including "systime.h" rather than by
18626 declaring it ourselves. (Bug#8664)
18628 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18629 * image.c (clear_image_cache): Likewise.
18631 * term.c (term_mouse_position): Don't assume time_t wraparound.
18633 Be more systematic about user-interface timestamps.
18634 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18635 and sometimes 'EMACS_UINT', to represent these timestamps.
18636 This change causes it to use 'Time' uniformly, as that's what X uses.
18637 This makes the code easier to follow, and makes it easier to catch
18638 integer overflow bugs such as Bug#8664.
18639 * frame.c (Fmouse_position, Fmouse_pixel_position):
18640 Use Time, not unsigned long, for user-interface timestamps.
18641 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18642 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18643 * keyboard.h (last_event_timestamp): Likewise.
18644 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18645 * menu.h (xmenu_show): Likewise.
18646 * term.c (term_mouse_position): Likewise.
18647 * termhooks.h (struct input_event.timestamp): Likewise.
18648 (struct terminal.mouse_position_hook): Likewise.
18649 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18650 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18651 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18652 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18653 what it was before.
18654 * menu.h, termhooks.h: Include "systime.h", for Time.
18656 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18657 Don't assume that the difference between two unsigned long values
18658 can fit into an integer. At this point, we know button_down_time
18659 <= event->timestamp, so the difference must be nonnegative, so
18660 there's no need to cast the result if double-click-time is
18661 nonnegative, as it should be; check that it's nonnegative, just in
18662 case. This bug is triggered when events are more than 2**31 ms
18663 apart (about 25 days). (Bug#8664)
18665 * xselect.c (last_event_timestamp): Remove duplicate decl.
18666 (x_own_selection): Remove needless cast to unsigned long.
18668 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18669 that always fit in int. Use a sentinel instead of a counter, to
18670 avoid a temp and to allay GCC's concerns about possible int overflow.
18671 * frame.h (struct frame): Use int for menu_bar_items_used
18672 instead of EMACS_INT, since it always fits in int.
18674 * menu.c (grow_menu_items): Check for int overflow.
18676 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18678 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18679 Before, the code was not consistent. These values cannot exceed
18680 2**31 - 1 so there's no need to make them unsigned.
18681 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18682 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18683 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18685 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18687 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18688 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18689 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18690 presumably because the widths might not match.
18692 * window.c (size_window): Avoid needless test at loop start.
18694 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18696 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18698 2011-05-12 Drew Adams <drew.adams@oracle.com>
18700 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18702 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18704 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18705 `width' to `bar_area_x' and `bar_area_width', respectively.
18706 (x_scroll_run): Take account of fringe background extension.
18708 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18709 Rename local vars `left' and `width' to `bar_area_x' and
18710 `bar_area_width', respectively.
18711 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18712 background extension.
18714 2011-05-10 Jim Meyering <meyering@redhat.com>
18716 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18718 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18720 * image.c (Finit_image_library): Return t for built-in image types,
18721 like pbm and xbm. (Bug#8640)
18723 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18725 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18727 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18729 * w32console.c (Fset_screen_color): Doc fix.
18730 (Fget_screen_color): New function.
18731 (syms_of_ntterm): Defsubr it.
18733 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18734 unlink the temporary file if Fcall_process didn't create it in the
18736 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18737 child process will be redirected to a file specified with `:file'.
18738 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18739 cue to call_process_cleanup not to close that handle.
18741 2011-05-07 Ben Key <bkey76@gmail.com>
18743 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18744 one of two shell specific rules, either bootstrap-temacs-CMD or
18745 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18746 to the previous implementation of the bootstrap-temacs rule.
18747 The bootstrap-temacs-CMD rule is similar to the previous
18748 implementation of the bootstrap-temacs rule except that it
18749 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18752 These changes, along with some changes to nt/configure.bat,
18753 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18754 earlier fix to add support for --cflags and --ldflags options
18755 that include quotes so that it works whether make uses cmd or
18758 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18760 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18761 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18763 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18764 a string. Handle both cases.
18765 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18766 (Fdbus_register_method): Use Qinvalid_function.
18768 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18770 * makefile.w32-in: Update dependencies.
18771 (LISP_H): Add inttypes.h and stdin.h.
18772 (PROCESS_H): Add unistd.h.
18774 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18776 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18777 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18779 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18781 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18783 * term.c (vfatal): Remove stray call to va_end.
18784 It's not needed and the C Standard doesn't allow it here anyway.
18786 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18787 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18789 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18792 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18794 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18796 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18798 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18800 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18802 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18803 * charset.c (Fdefine_charset_internal): Don't initialize
18804 charset.code_space[15]. The value was garbage, on hosts with
18805 32-bit int (Bug#8600).
18807 * lread.c (read_integer): Be more consistent with string-to-number.
18808 Use string_to_number to do the actual conversion; this avoids
18809 rounding errors and fixes some other screwups. Without this fix,
18810 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18811 (digit_to_number): Move earlier, for benefit of read_integer.
18812 Return -1 if the digit is out of range for the base, -2 if it is
18813 not a digit in any supported base. (Bug#8602)
18815 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18817 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18818 to match comment at start of function. This also removes a
18819 GCC warning about overflow in a 32+64-bit port.
18821 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18823 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18824 Reported by Stefan Monnier in
18825 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18826 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18827 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18829 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18830 (EMACS_UINTPTR): Likewise, with uintptr_t.
18832 * lisp.h: Prefer 64-bit EMACS_INT if available.
18833 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18834 on 32-bit hosts that have 64-bit int, so that they can access
18836 However, temporarily disable this change unless the temporary
18837 symbol WIDE_EMACS_INT is defined.
18839 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18841 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18842 This removes an assumption that EMACS_INT and long are the same
18843 width as pointers. The assumption is true for Emacs porting targets
18844 now, but we want to make other targets possible.
18845 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18846 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18847 In the rest of the code, change types of integers that hold casted
18848 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18849 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18850 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18851 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18852 No need to cast type when ORing.
18853 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18854 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18855 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18856 assume EMACS_INT is the same width as char *.
18857 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18858 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18859 Remove no-longer-needed casts.
18860 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18861 (xg_tool_bar_help_callback, xg_make_tool_item):
18862 Use EMACS_INTPTR to hold an integer
18863 that will be cast to void *; this can avoid a GCC warning
18864 if EMACS_INT is not the same width as void *.
18865 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18866 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18867 (current_message_1, set_message_1):
18868 Use a local to convert to proper width without a cast.
18869 * xmenu.c (dialog_selection_callback): Likewise.
18871 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18872 Also, don't assume VALBITS / RAND_BITS is less than 5,
18873 and don't rely on undefined behavior when shifting a 1 left into
18875 * lisp.h (get_random): Change signature to match.
18877 * lread.c (hash_string): Use size_t, not int, for hash computation.
18878 Normally we prefer signed values; but hashing is special, because
18879 it's better to use unsigned division on hash table sizes so that
18880 the remainder is nonnegative. Also, size_t is the natural width
18881 for hashing into memory. The previous code used 'int', which doesn't
18882 retain enough info to hash well into very large tables.
18883 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18885 * dbusbind.c: Don't possibly lose pointer info when converting.
18886 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18887 Use XPNTR rather than XHASH, so that the high-order bits of
18888 the pointer aren't lost when converting through void *.
18890 * eval.c (Fautoload): Don't double-shift a pointer.
18892 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18894 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18896 * gnutls.c (DEF_GNUTLS_FN):
18897 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18899 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18901 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18904 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18906 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18907 New version that can reserve upto 2GB of heap space.
18909 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18911 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

18915 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18916 `gnutls_certificate_set_x509_key_file'.
18918 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18920 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18921 Update dependencies.
18923 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18925 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18926 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18927 Remove unused parameter `fildes'.
18928 * process.c (read_process_output, send_process): Don't pass it.
18930 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18932 Fix previous change: the library cache is defined in w32.c.
18933 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18934 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18936 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18938 Implement dynamic loading of GnuTLS on Windows.
18940 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18941 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18942 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18945 * gnutls.c (Qgnutls_dll): Define.
18946 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18947 (gnutls_*): Declare function pointers.
18948 (init_gnutls_functions): New function to initialize function pointers.

18951 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18952 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18953 (emacs_gnutls_write, emacs_gnutls_read)
18954 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18955 (Fgnutls_available_p): New function.
18956 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

18958 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18960 * image.c: Include w32.h.
18961 (Vimage_type_cache): Delete.

18963 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18964 (w32_delayed_load): Move to w32.c.
18966 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18968 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18969 (w32_delayed_load): Move from image.c. When loading a library, record
18970 its filename in the :loaded-from property of the library id.
18971 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18972 Initialize and staticpro them.
18973 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18975 * process.c: Include lisp.h before w32.h, not after.
18976 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18977 instead of gnutls_record_check_pending.
18979 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18981 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18983 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18984 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18987 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18989 * xterm.c (x_set_frame_alpha): Do not set property on anything

19012 * sysdep.c (wait_for_termination_1): Make static.
19013 (wait_for_termination, interruptible_wait_for_termination):
19014 Move after wait_for_termination_1.
19016 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
19018 * sysdep.c (interruptible_wait_for_termination): New function
19019 which is like wait_for_termination, but allows keyboard
19022 * callproc.c (Fcall_process): Add (:file "file") as an option for
19024 (Fcall_process_region): Ditto.
19026 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19028 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19029 rather than `XVECTOR (FOO)->size'.
19031 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19032 inttypes.h, as a gnulib replacement is used if it not available in
19035 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19037 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19038 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19039 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19041 * coding.c (coding_alloc_by_realloc): Error out if destination
19042 will grow beyond MOST_POSITIVE_FIXNUM.
19043 (decode_coding_emacs_mule): Abort if there isn't enough place in

19056 * window.c (window_scroll_line_based): Use a marker instead of
19057 simple variables to record original value of point. (Bug#7952)
19059 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19060 produced by %s or %c overflows available buffer space. (Bug#8545)
19062 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19064 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19065 (SIZE_MAX): Move defn after all includes, as they might #define it.
19067 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19069 * w32.c (init_environment): Warn about defaulting HOME to C:\.

19099 Improve `doprnt' and its usage. (Bug#8545)
19100 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19101 `format_end'. Remove support for %l as a conversion specifier.
19102 Don't use xrealloc. Improve diagnostics when the %l size modifier
19103 is used. Update the commentary.
19105 * eval.c (verror): Simplify calculation of size_t.
19107 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19110 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19112 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19115 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19117 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19118 This makes this file independent of the recent pseudovector change.
19120 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19122 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19124 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19125 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19126 Remove unused local.
19127 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19129 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19130 GCC 4.6.0 optimizes based on type-based alias analysis.
19131 For example, if b is of type struct buffer * and v of type struct
19132 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19133 != &v->size, and therefore "v->size = 1; b->size = 2; return
19134 v->size;" must therefore return 1. This assumption is incorrect
19135 for Emacs, since it type-puns struct Lisp_Vector * with many other
19136 types. To fix this problem, this patch adds a new type struct
19137 vectorlike_header that documents the constraints on layout of vectors
19138 and pseudovectors, and helps optimizing compilers not get fooled
19139 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19140 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19141 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19143 (XSETPVECTYPE): Rewrite in terms of new macro.
19144 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19145 This is a bit clearer, and further avoids the possibility of
19146 undesirable aliasing.
19147 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19148 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19149 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19150 since Lisp_Subr is a special case (no "next" field).
19151 (ASIZE): Now uses header.size rather than size.
19152 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19153 to avoid the hassle of writing XVECTOR (foo)->header.size.
19154 (struct vectorlike_header): New type.
19155 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19156 object, to help avoid aliasing.
19157 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19158 (SUBRP): Likewise, since Lisp_Subr is a special case.
19159 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19160 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19161 (struct Lisp_Hash_Table): Combine first two members into a single
19162 struct vectorlike_header member. All uses of "size" and "next" members
19163 changed to be "header.size" and "header.next".
19164 * buffer.h (struct buffer): Likewise.
19165 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19166 * frame.h (struct frame): Likewise.
19167 * process.h (struct Lisp_Process): Likewise.
19168 * termhooks.h (struct terminal): Likewise.
19169 * window.c (struct save_window_data, struct saved_window): Likewise.
19170 * window.h (struct window): Likewise.
19171 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19172 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19173 * buffer.c (init_buffer_once): Likewise.
19174 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19176 * process.c (Fformat_network_address): Use local var for size,
19179 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19181 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19182 * data.c (atof): Remove decl; no longer used or needed.
19183 (digit_to_number): Move to lread.c.
19184 (Fstring_to_number): Use new string_to_number function, to be
19185 consistent with how the Lisp reader treats infinities and NaNs.
19186 Do not assume that floating-point numbers represent EMACS_INT
19187 without losing information; this is not true on most 64-bit hosts.
19188 Avoid double-rounding errors, by insisting on integers when
19189 parsing non-base-10 numbers, as the documentation specifies.
19190 * lisp.h (string_to_number): New decl, replacing ...
19191 (isfloat_string): Remove.
19192 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19193 (read1): Do not accept +. and -. as integers; this
19194 appears to have been a coding error. Similarly, do not accept
19195 strings like +-1e0 as floating point numbers. Do not report
19196 overflow for integer overflows unless the base is not 10 which
19197 means we have no simple and reliable way to continue.
19198 Break out the floating-point parsing into a new
19199 function string_to_number, so that Fstring_to_number parses
19200 floating point numbers consistently with the Lisp reader.
19201 (digit_to_number): Move here from data.c. Make it static inline.
19202 (E_CHAR, EXP_INT): Remove, replacing with ...
19203 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19204 (string_to_number): New function, replacing isfloat_string.
19205 This function checks for valid syntax and produces the resulting
19206 Lisp float number too. Rework it so that string-to-number
19207 no longer mishandles examples like "1.0e+". Use strtoumax,
19208 so that overflow for non-base-10 numbers is reported only when
19209 there's no portable and simple way to convert to floating point.
19211 * textprop.c (set_text_properties_1): Rewrite for clarity,
19212 and to avoid GCC warning about integer overflow.
19214 * intervals.h (struct interval): Use EMACS_INT for members
19215 where EMACS_UINT might cause problems. See
19216 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19217 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19218 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19220 (offset_intervals): Tell GCC not to worry about length overflow
19221 when negating a negative length.
19223 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19224 (overrun_check_free): Likewise.
19226 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19227 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
19230 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19231 (gnutls_make_error): Rename local to avoid shadowing.
19232 (gnutls_emacs_global_deinit): ifdef out; not used.
19233 (Fgnutls_boot): Use const for pointer to readonly storage.
19234 Comment out unused local. Fix pointer signedness problems.
19236 * lread.c (openp): Don't stuff size_t into an 'int'.
19237 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19238 about possible signed overflow.
19240 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19241 (GDK_KEY_g): Don't define if already defined.
19242 (xg_prepare_tooltip): Avoid pointer signedness problem.
19243 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19245 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19246 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19248 * xfns.c (Fx_window_property): Simplify a bit,
19249 to make a bit faster and to avoid GCC 4.6.0 warning.
19250 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19252 * fns.c (internal_equal): Don't assume size_t fits in int.
19254 * alloc.c (compact_small_strings): Tighten assertion a little.
19256 Replace pEd with more-general pI, and fix some printf arg casts.
19257 * lisp.h (pI): New macro, generalizing old pEd macro to other
19258 conversion specifiers. For example, use "...%"pI"d..." rather
19259 than "...%"pEd"...".
19260 (pEd): Remove. All uses replaced with similar uses of pI.
19261 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19262 * alloc.c (check_pure_size): Don't overflow by converting size to int.
19263 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
19264 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
19265 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
19266 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
19267 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
19269 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
19270 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
19271 * print.c (safe_debug_print, print_object): Likewise.
19272 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
19274 Use pI instead of if-then-else-abort. Use %p to avoid casts,
19275 avoiding the 0 flag, which is not portable.
19276 * process.c (Fmake_network_process): Use pI to avoid cast.
19277 * region-cache.c (pp_cache): Likewise.
19278 * xdisp.c (decode_mode_spec): Likewise.
19279 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
19280 behavior on 64-bit hosts with printf arg.
19281 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
19282 (x_stop_queuing_selection_requests): Likewise.
19283 (x_get_window_property): Don't truncate byte count to an 'int'
19286 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
19287 here, since it parses constructs like leading '-' and spaces,
19288 which are not wanted; and it overflows with large numbers.
19289 Instead, simply match F[0-9]+, which is what is wanted anyway.
19291 * alloc.c: Remove unportable assumptions about struct layout.
19292 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
19293 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
19294 (allocate_vectorlike, make_pure_vector): Use the new macros,
19295 plus offsetof, to remove unportable assumptions about struct layout.
19296 These assumptions hold on all porting targets that I know of, but
19297 they are not guaranteed, they're easy to remove, and removing them
19298 makes further changes easier.
19300 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
19301 This doesn't fix a bug but makes the code clearer.
19302 (string_overrun_cookie): Now const. Use initializers that
19303 don't formally overflow signed char, to avoid warnings.
19304 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
19305 can cause Emacs to crash when string overrun checking is enabled.
19306 (allocate_buffer): Don't assume sizeof (struct buffer) is a
19307 multiple of sizeof (EMACS_INT); it need not be, if
19308 alignof(EMACS_INT) < sizeof (EMACS_INT).
19309 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
19311 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

19318 supposed to be handshaking. (Bug#8556)
19319 Reported by Paul Eggert <eggert@cs.ucla.edu>.
19321 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

19331 * alloc.c (check_sblock, check_string_bytes)
19332 (check_string_free_list): Convert to standard C.
19334 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
19336 * w32.c (emacs_gnutls_push): Fix typo.
19338 2011-04-25 Eli Zaretskii <eliz@gnu.org>
19340 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
19341 "cast to pointer from integer of different size".
19343 Improve doprnt and its use in verror. (Bug#8545)
19344 * doprnt.c (doprnt): Document the set of format control sequences
19345 supported by the function. Use SAFE_ALLOCA instead of always
19348 * eval.c (verror): Don't limit the buffer size at size_max-1, that
19349 is one byte too soon. Don't use xrealloc; instead xfree and
19352 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
19354 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
19357 * gnutls.c: Renamed global_initialized to
19358 gnutls_global_initialized. Added internals for the
19359 :verify-hostname-error, :verify-error, and :verify-flags
19360 parameters of `gnutls-boot' and documented those parameters in the
19361 docstring. Start callback support.
19362 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
19363 unless a fatal error occurred. Call gnutls_alert_send_appropriate
19364 on error. Return error code.
19365 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
19366 (emacs_gnutls_read): Likewise.
19367 (Fgnutls_boot): Return handshake error code.

19431 <char-direction-table>: Deleted.
19433 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19435 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19436 * doprnt.c: Include limits.h.
19437 (SIZE_MAX): New macro.
19438 (doprnt): Return a size_t value. 2nd arg is now size_t.
19439 Many local variables are now size_t instead of int or unsigned.
19440 Improve overflow protection. Support `l' modifier for integer
19441 conversions. Support %l conversion. Don't assume an EMACS_INT
19442 argument for integer conversions and for %c.
19444 * lisp.h (doprnt): Restore prototype.
19446 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19447 $(SRC)/character.h.
19449 * Makefile.in (base_obj): Add back doprnt.o.
19451 * deps.mk (doprnt.o): Add back prerequisites.
19452 (callint.o): Depend on character.h.
19454 * eval.c (internal_lisp_condition_case): Include the handler
19455 representation in the error message.
19456 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19457 when breaking from the loop.
19459 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19461 * callint.c (Fcall_interactively): When displaying error message
19462 about invalid control letter, pass the character's codepoint, not
19463 a pointer to its multibyte form. Improve display of the character
19464 in octal and display also its hex code.
19466 * character.c (char_string): Use %x to display the (unsigned)
19467 codepoint of an invalid character, to avoid displaying a bogus
19470 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19471 `error', not SYMBOL_NAME itself.
19473 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19474 character arguments to `error'.
19476 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19477 to `error' in error message about FINAL_CHAR argument. Make sure
19478 FINAL_CHAR is a character, and use %c when it is passed as
19479 argument to `error'.

19543 Define only if needed.
19545 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
19546 by pacifying GCC about it. Maybe it's time to retire it?
19547 * xfaces.c (USG, __TIMEVAL__): Likewise.
19549 * dispextern.h (struct redisplay_interface): Rename param
19550 to avoid shadowing.
19551 * termhooks.h (struct terminal): Likewise.
19552 * xterm.c (xembed_send_message): Likewise.
19554 * insdel.c (make_gap_smaller): Define only if
19555 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
19557 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
19560 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
19561 so that we aren't warned about unused symbols.

20014 * ccl.h (check_ccl_update, Vccl_program_table): Remove decls.
20015 * ccl.c (Vccl_program_table): Now static.
20016 (check_ccl_update): Remove; unused.
20018 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
20019 * category.h: ... from here.
20020 * category.c (check_category_table, set_category_set): Now static.
20022 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
20023 * lisp.h: Remove these decls.
20025 * buffer.c (buffer_count): Remove unused var.
20027 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
20028 so that it's not optimized away.
20029 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
20030 * dispextern.h (bidi_dump_cached_states): Remove, since it's
20031 exported only to the debugger.
20033 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
20034 * atimer.h (run_all_atimers): Remove; not exported.
20036 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
20037 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
20038 was inaccessible from Lisp.
20039 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
20040 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
20042 alloc.c: Import and export fewer symbols, and remove unused items.
20043 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
20045 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
20046 it's not optimized away by whole-program optimization.
20047 (message_enable_multibyte, free_misc): Remove.
20048 (catchlist, handlerlist, mark_backtrace):
20049 Declare only if BYTE_MARK_STACK.
20050 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
20051 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
20052 (message_enable_multibyte): Remove decl.
20053 (free_misc, interval_free_list, float_block, float_block_index):

20055 (cons_free_list, last_marked_index):
20057 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
20058 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
20059 (mark_backtrace): Define only if BYTE_MARK_STACK.
20060 * xdisp.c (message_enable_multibyte): Now static.
20062 Declare Lisp_Object Q* variables to be 'static' if not exported.
20063 This makes it easier for human readers (and static analyzers)
20064 to see whether these variables are used from other modules.
20065 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
20066 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
20067 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

20070 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
20071 * xmenu.c, xselect.c:
20072 Declare Q* vars static if they are not used in other modules.
20073 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
20074 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
20075 Remove decls of unexported vars.
20076 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
20078 * lisp.h (DEFINE_FUNC): Make sname 'static'.
20080 Make Emacs functions such as Fatom 'static' by default.
20081 This makes it easier for human readers (and static analyzers)
20082 to see whether these functions can be called from other modules.
20083 DEFUN now defines a static function. To make the function external
20084 so that it can be used in other C modules, use the new macro DEFUE.
20085 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
20086 (Finit_image_library):
20087 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
20088 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
20089 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
20090 Remove decls, since these functions are now static.
20091 (Funintern, Fget_internal_run_time): New decls, since these functions
20092 were already external.
20094 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
20095 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

20101 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
20102 Mark functions with DEFUE instead of DEFUN,
20103 if they are used in other modules.
20104 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
20105 decls for now-static functions.
20106 * buffer.h (Fdelete_overlay): Remove decl.
20107 * callproc.c (Fgetenv_internal): Mark as internal.

20115 * fileio.c (Fmake_symbolic_link): New forward static decl.
20116 * image.c (Finit_image_library): New forward static decl.
20117 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
20118 * intervals.h (Fprevious_property_change):
20119 (Fremove_list_of_text_properties): Remove decls.
20120 * keyboard.c (Fthis_command_keys): Remove decl.
20121 (Fcommand_execute): New forward static decl.
20122 * keymap.c (Flookup_key): New forward static decl.
20123 (Fcopy_keymap): Now static.
20124 * keymap.h (Flookup_key): Remove decl.
20125 * process.c (Fget_process): New forward static decl.
20126 (Fprocess_datagram_address): Mark as internal.

20142 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20144 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20145 when at ZV. (Bug#8487)
20147 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20149 * charset.c (Fclear_charset_maps): Use xfree instead of free.
20151 * keyboard.c (parse_tool_bar_item): Likewise.
20152 * sound.c (sound_cleanup, alsa_close): Likewise.
20153 * termcap.c (tgetent): Likewise.
20154 * xfns.c (x_default_font_parameter): Likewise.
20155 * xsettings.c (read_and_apply_settings): Likewise.
20157 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20158 (overrun_check_free): Protoize.
20160 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20162 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20163 since callers should never pass a negative size.
20164 Change the signature to match that of plain 'read' and 'write'; see
20165 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20166 * lisp.h: Update prototypes of emacs_write and emacs_read.
20168 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20170 * xdisp.c (redisplay_window): Don't try to determine the character
20171 position of the scroll margin if the window start point w->startp
20172 is outside the buffer's accessible region. (Bug#8468)
20174 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20176 Fix write-region and its subroutines for buffers > 2GB.
20177 * fileio.c (a_write, e_write): Modify declaration of arguments and
20178 local variables to support buffers larger than 2GB.
20179 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20181 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20182 argument, local variables, and return value.
20184 * lisp.h: Update prototypes of emacs_write and emacs_read.
20186 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20188 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20190 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20192 Fix more problems found by GCC 4.6.0's static checks.
20194 * xdisp.c (vmessage): Use a better test for character truncation.
20196 * charset.c (load_charset_map): <, not <=, for optimization,
20197 and to avoid potential problems with integer overflow.
20198 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20199 * casetab.c (set_identity, shuffle): Likewise.
20200 * editfns.c (Fformat): Likewise.
20201 * syntax.c (skip_chars): Likewise.
20203 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20204 This also lets GCC 4.6.0 generate slightly better loop code.
20206 * callint.c (Fcall_interactively): <, not <=, for optimization.
20207 (Fcall_interactively): Count the number of arguments produced,
20208 not the number of arguments given. This is simpler and lets GCC
20209 4.6.0 generate slightly better code.
20211 * ftfont.c: Distingish more carefully between FcChar8 and char.
20212 The previous code passed unsigned char * to a functions like
20213 strlen and xstrcasecmp that expect char *, which does not
20214 conform to the C standard.
20215 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20216 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20217 char * when the C standard requires it.
20219 * keyboard.c (read_char): Remove unused var.
20221 * eval.c: Port to Windows vsnprintf (Bug#8435).
20222 Include <limits.h>.
20223 (SIZE_MAX): Define if the headers do not.
20224 (verror): Do not give up if vsnprintf returns a negative count.
20225 Instead, grow the buffer. This ports to Windows vsnprintf, which
20226 does not conform to C99. Problem reported by Eli Zaretskii.
20227 Also, simplify the allocation scheme, by avoiding the need for
20228 calling realloc, and removing the ALLOCATED variable.
20230 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20232 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20233 But keep the doprint source code for now, as we might revamp it
20234 and use it again (Bug#8435).
20235 * lisp.h (doprnt): Remove.
20236 * Makefile.in (base_obj): Remove doprnt.o.
20237 * deps.mk (doprnt.o): Remove.
20239 error: Print 32- and 64-bit integers portably (Bug#8435).
20240 Without this change, on typical 64-bit hosts error ("...%d...", N)
20241 was used to print both 32- and 64-bit integers N, which relied on
20242 undefined behavior.
20243 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20244 * lisp.h (error, verror): Mark as printf-like functions.
20245 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20246 Report overflow in size calculations when allocating printf buffer.
20247 Do not truncate output string at its first null byte.
20248 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20249 Truncate the output at a character boundary, since vsnprintf does not
20251 * charset.c (check_iso_charset_parameter): Convert internal
20252 character to string before calling 'error', since %c now has the
20254 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20255 overflow when computing char to be passed to 'error'. Do not
20256 pass Lisp_Object to 'error'; pass the integer instead.
20257 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20258 formatted with plain %d.
20260 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20262 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20264 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
20266 * xterm.c (x_catch_errors): Remove duplicate declaration.
20268 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
20270 * xdisp.c, lisp.h (message_nolog): Remove; unused.
20272 2011-04-10 Jim Meyering <meyering@redhat.com>
20274 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
20275 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
20276 return ssize_t not "int", and use size_t as the buffer length.
20277 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
20278 * gnutls.h: Update declarations.
20279 * process.c (read_process_output): Use ssize_t, to match.
20280 (send_process): Likewise.
20282 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20284 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
20286 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
20288 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
20289 Use unsigned char, to match FcChar8 type definition.
20291 * xterm.c (handle_one_xevent):
20292 * xmenu.c (create_and_show_popup_menu):
20293 * xselect.c (x_decline_selection_request)
20294 (x_reply_selection_request): Avoid type-punned deref of X events.
20296 2011-04-09 Eli Zaretskii <eliz@gnu.org>
20298 Fix some uses of `int' instead of EMACS_INT.
20299 * search.c (string_match_1, fast_string_match)
20300 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
20301 (scan_buffer, find_next_newline_no_quit)
20302 (find_before_next_newline, search_command, Freplace_match)
20303 (Fmatch_data): Make some `int' variables be EMACS_INT.
20305 * xdisp.c (display_count_lines): 3rd argument and return value now
20306 EMACS_INT. All callers changed.
20307 (pint2hrstr): Last argument is now EMACS_INT.
20309 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
20310 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
20311 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
20312 (decode_coding_utf_16, decode_coding_emacs_mule)

20314 (decode_coding_ccl, decode_coding_charset)
20315 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
20316 (decode_coding_iso_2022, decode_coding_emacs_mule)
20317 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
20318 <char_offset, last_offset>: Declare EMACS_INT.

20320 (encode_coding_emacs_mule, encode_invocation_designation)
20321 (encode_designation_at_bol, encode_coding_iso_2022)
20322 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
20323 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
20325 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
20326 (encode_invocation_designation): Last argument P_NCHARS is now
20328 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
20329 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
20331 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
20334 * ccl.c (Fccl_execute_on_string): Declare some variables
20337 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
20339 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
20341 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
20343 * process.c (Fformat_network_address): Doc fix.
20345 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
20347 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
20349 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
20351 * keyboard.c (read_char): Call Lisp function help-form-show,
20352 instead of using internal_with_output_to_temp_buffer.
20353 (Qhelp_form_show): New var.
20354 (syms_of_keyboard): Use DEFSYM macro.
20356 * print.c (internal_with_output_to_temp_buffer): Function deleted.

20360 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
20362 * process.c (Flist_processes): Remove to Lisp.
20363 (list_processes_1): Delete.
20365 2011-04-06 Eli Zaretskii <eliz@gnu.org>
20367 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
20369 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
20371 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
20373 Fix more problems found by GCC 4.6.0's static checks.
20375 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
20377 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
20379 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
20381 * xdisp.c (vmessage): Mark as a printf-like function.
20383 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
20385 * sound.c (sound_warning): Don't crash if arg contains a printf format.
20387 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
20388 printf-like functions.
20389 (tiff_load): Add casts to remove these marks before passing them
20390 to system-supplied API.
20392 * eval.c (Fsignal): Remove excess argument to 'fatal'.
20394 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
20395 This avoids several warnings with gcc -Wstrict-overflow.
20396 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20397 directly, rather than having caller test rule sign. This avoids
20398 some unnecessary tests.
20399 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20400 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20401 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20403 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20404 (xfont_open): Avoid unnecessary tests.
20406 * composite.c (composition_gstring_put_cache): Use unsigned integer.

20415 by using the new macro.
20417 * textprop.c (set_text_properties_1): Change while to do-while,
20418 since the condition is always true at first.
20420 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20421 (interval_deletion_adjustment): Return unsigned value.
20424 * process.c (list_processes_1, create_pty, read_process_output):
20425 (exec_sentinel): Remove vars that were set but not used.
20426 (create_pty): Remove unnecessary "volatile"s.

20429 (read_process_output): Simplify nbytes computation if buffered.
20431 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
20433 * syntax.c (scan_words): Remove var that was set but not used.
20434 (update_syntax_table): Use unsigned instead of int.
20436 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

20440 * print.c (print_error_message): Avoid int overflow.
20442 * font.c (font_list_entities): Redo for clarity,
20443 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

20458 (wordify): Omit three unnecessary tests.
20460 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20461 All callers changed. This avoids the need for an unused var.
20463 * casefiddle.c (casify_region): Remove var that is set but not used.
20465 * dired.c (file_name_completion): Remove var that is set but not used.
20467 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20469 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20470 (Finsert_file_contents): Remove unnecessary code checking fd.
20472 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20473 Check for integer overflow on size calculations.
20475 * buffer.c (Fprevious_overlay_change): Remove var that is set
20478 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20479 Remove vars that are set but not used.
20480 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20481 (timer_check_2): Mark vars as initialized.
20483 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20485 * image.c (lookup_image): Remove var that is set but not used.
20486 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20488 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20489 that are set but not used.
20491 * xfns.c (make_invisible_cursor): Don't return garbage
20492 if XCreateBitmapFromData fails (Bug#8410).
20494 * xselect.c (x_get_local_selection, x_handle_property_notify):
20495 Remove vars that are set but not used.
20497 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20498 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20500 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20501 Remove var that is set but not used.
20502 (scroll_bar_windows_size): Now size_t, not int.
20503 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20504 Check for overflow.
20506 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20507 (map_tty_color) [!defined MSDOS]: Likewise.
20509 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20511 * coding.c: Remove vars that are set but not used.
20512 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20513 All callers changed.
20514 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20515 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20516 (decode_coding_charset): Remove vars that are set but not used.
20518 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20519 that is set but not used.
20521 * print.c (print_object): Remove var that is set but not used.
20523 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20524 The gnulib version avoids calling malloc in the usual case,
20525 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20526 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20527 * filelock.c (current_lock_owner): Likewise.
20528 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20529 * sysdep.c: Include allocator.h, careadlinkat.h.
20530 (emacs_no_realloc_allocator): New static constant.
20531 (emacs_readlink): New function.
20532 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20533 ../lib/careadlinkat.h.
20535 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20537 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20538 first non-nil return value).

20554 (get_per_char_metric): Remove parameter `f', unused since
20555 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20557 2011-04-02 Jim Meyering <meyering@redhat.com>
20559 do not dereference NULL upon failed strdup
20560 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20561 (ns_get_family): Likewise.
20563 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20565 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20567 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20569 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20572 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20574 Add lexical binding.
20576 * window.c (Ftemp_output_buffer_show): New fun.
20577 (Fsave_window_excursion):
20578 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20580 * lread.c (lisp_file_lexically_bound_p): New function.
20581 (Fload): Bind Qlexical_binding.
20582 (readevalloop): Remove `evalfun' arg.
20583 Bind Qinternal_interpreter_environment.
20584 (Feval_buffer): Bind Qlexical_binding.
20585 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20587 (syms_of_lread): Declare `lexical-binding'.
20589 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20591 * keyboard.c (eval_dyn): New fun.
20592 (menu_item_eval_property): Use it.
20594 * image.c (parse_image_spec): Use Ffunctionp.
20596 * fns.c (concat, mapcar1): Accept byte-code-functions.
20598 * eval.c (Fsetq): Handle lexical vars.
20599 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20600 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20601 (FletX, Flet): Obey lexical binding.
20602 (Fcommandp): Handle closures.
20603 (Feval): New `lexical' arg.
20604 (eval_sub): New function extracted from Feval. Use it almost
20605 everywhere where Feval was used. Look up vars in lexical env.
20607 (Ffunctionp): Move from subr.el.
20608 (Ffuncall): Handle closures.
20609 (apply_lambda): Remove `eval_flags'.
20610 (funcall_lambda): Handle closures and new byte-code-functions.
20611 (Fspecial_variable_p): New function.
20612 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20613 but without exporting it to Lisp.
20615 * doc.c (Fdocumentation, store_function_docstring):
20616 * data.c (Finteractive_form): Handle closures.
20618 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20621 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20623 (exec_byte_code): New function extracted from Fbyte_code to handle new
20624 calling convention for byte-code-functions. Add new byte-codes.
20626 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20628 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20630 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20632 * xdisp.c (redisplay_internal): Fix prototype.
20634 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20636 * xdisp.c (SCROLL_LIMIT): New macro.
20637 (try_scrolling): Use it when setting scroll_limit.
20638 Limit scrolling to 100 screen lines.
20639 (redisplay_window): Even when falling back on "recentering",
20640 position point in the window according to scroll-conservatively,
20641 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20643 (try_scrolling): When point is above the window, allow searching
20644 as far as scroll_max, or one screenful, to compute vertical
20645 distance from PT to the scroll margin position. This prevents
20646 try_scrolling from unnecessarily failing when
20647 scroll-conservatively is set to a value slightly larger than the
20648 window height. Clean up the case of PT below the margin at bottom
20649 of window: scroll_max can no longer be INT_MAX. When aggressive
20650 scrolling is in use, don't let point enter the opposite scroll
20651 margin as result of the scroll.
20652 (syms_of_xdisp) <scroll-conservatively>: Document the
20653 threshold of 100 lines for never-recentering scrolling.
20655 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20657 * dispextern.h (move_it_by_lines):
20658 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20659 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20660 (message_log_check_duplicate): Remove parameters `prev_bol' and
20661 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20662 (redisplay_internal): Remove parameter `preserve_echo_area',
20663 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20665 * indent.c (Fvertical_motion):
20666 * window.c (window_scroll_pixel_based, Frecenter):
20667 Don't pass `need_y_p' to `move_it_by_lines'.
20669 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20671 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20672 steal a few bits to be more compact.
20673 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20674 Remove unneeded casts.
20676 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20678 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20680 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20681 binding" message (bug#7967).
20683 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20685 Fix more problems found by GCC 4.6.0's static checks.
20687 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20688 Remove unused local var.
20690 * editfns.c (Fmessage_box): Remove unused local var.
20692 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20693 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20694 Omit unused local vars.
20695 * window.c (shrink_windows): Omit unused local var.
20696 * menu.c (digest_single_submenu): Omit unused local var.
20697 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20698 Omit unused local var.
20700 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20701 Don't assume string length fits in int.
20702 (keyremap_step, read_key_sequence): Use size_t for sizes.
20703 (read_key_sequence): Don't check last_real_key_start redundantly.
20705 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20706 instead of alloca (Bug#8344).
20708 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20709 (Fbacktrace_frame): Don't assume nframes fits in int.
20711 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20713 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20716 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20718 * cm.c (calccost): Turn while-do into do-while, for clarity.
20720 * keyboard.c (syms_of_keyboard): Use the same style as later
20721 in this function when indexing through an array. This also
20722 works around GCC bug 48267.
20724 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20726 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20728 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20729 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20731 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20732 This avoids undefined behavior on integer overflow, and is a bit
20733 more convenient anyway since it is compared to a size_t variable.
20735 Variadic C functions now count arguments with size_t, not int.
20736 This avoids an unnecessary limitation on 64-bit machines, which
20737 caused (substring ...) to crash on large vectors (Bug#8344).

20747 * fns.c (concat): Likewise.
20748 * frame.c (x_set_frame_parameters): Likewise.
20749 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20750 0 if not found, not -1. All callers changed.
20752 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20753 (stack_copy_size): Now size_t, not int.
20754 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20756 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20758 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20759 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20760 All callers changed.
20762 * lisp.h (multibyte_char_to_unibyte):
20763 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20764 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

20775 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20776 don't set the hook to nil, but remove the offending function instead.
20777 (Qcommand_hook_internal): Remove, unused.
20778 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20779 Vcommand_hook_internal.
20781 * eval.c (enum run_hooks_condition): Remove.
20782 (funcall_nil, funcall_not): New functions.
20783 (run_hook_with_args): Call each function through a `funcall' argument.
20784 Remove `cond' argument, now redundant.

20797 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20798 All callers changed.
20800 * w32.c (_wsa_errlist): Use braces for struct initializers.
20802 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
20803 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.

20855 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
20857 * keyboard.c (timer_check): Remove parameter `do_it_now',
20858 unused since 1996-04-12T06:01:29Z!rms@gnu.org.

20958 * callint.c (Fcall_interactively):
20959 * buffer.c (Fkill_all_local_variables):
20960 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20962 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20963 unconditionally since it does the check itself.
20965 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20967 Fix more problems found by GCC 4.5.2's static checks.
20969 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20970 the first time through the loop, since we know p0 < p1 then.
20971 This also avoids a gcc -Wstrict-overflow warning.
20973 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20974 leading to a memory leak, possible in functions like
20975 load_charset_map_from_file that can allocate an unbounded number
20976 of objects (Bug#8318).
20978 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20979 that could (at least in theory) be that large.
20981 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20982 This is less likely to overflow, and avoids undefined behavior if
20983 overflow does occur. All callers changed. Use strtoul to scan
20984 for the unsigned long integer.
20985 (pint2hrstr): Simplify and tune code slightly.
20986 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20996 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20999 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21001 * process.c (Fmake_network_process): Use socklen_t, not int,
21002 where POSIX says socklen_t is required in portable programs.
21003 This fixes a porting bug on hosts like 64-bit HP-UX, where
21004 socklen_t is wider than int (Bug#8277).
21005 (Fmake_network_process, server_accept_connection):
21006 (wait_reading_process_output, read_process_output):
21009 * process.c: Rename or move locals to avoid shadowing.

21019 Make tparam.h and terminfo.c consistent.
21020 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
21021 Include tparam.h instead, since it declares them.
21022 * cm.h (PC): Remove extern decl; tparam.h now does this.
21023 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21024 * terminfo.c: Include tparam.h, to check interfaces.
21025 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21026 (tparam): Adjust signature to match interface in tparam.h;
21027 this removes some undefined behavior. Check that outstring and len
21028 are zero, which they always are with Emacs.
21029 * tparam.h (PC, BC, UP): New extern decls.
21031 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
21032 (xftfont_open): Rename locals to avoid shadowing.

21049 (find_automatic_composition, composition_adjust_point): Likewise.
21050 (composition_update_it): Mark var as initialized.
21051 (find_automatic_composition): Mark vars as initialized,
21052 with a FIXME (Bug#8290).

21056 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
21057 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
21058 (BUF_DEC_POS): Be more systematic about renaming local temporaries
21059 to avoid shadowing.
21061 * textprop.c (property_change_between_p): Remove; unused.
21063 * intervals.c (interval_start_pos): Now static.
21065 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

21071 Fix pointer signedness.
21072 (alsa_choose_format): Remove unused local var.
21073 (wav_play): Initialize a variable to 0, to prevent undefined
21074 behavior (Bug#8278).
21076 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
21078 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21080 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21081 clobbering (Bug#8298).
21082 * sysdep.c (sys_subshell): Likewise.
21083 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21085 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21086 This should get cleaned up, so that child_setup has the
21087 same signature on all platforms.
21089 * callproc.c (call_process_cleanup): Now static.
21090 (relocate_fd): Rename locals to avoid shadowing.
21092 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21094 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21095 not to be necessary, and produces flickering.
21097 2011-03-20 Glenn Morris <rgm@gnu.org>
21099 * config.in: Remove file.
21101 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
21103 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
21104 are now in src/globals.h.
21105 (syms_of_minibuf): Remove spurious & from previous change.

21131 (sigchld_handler): Now static.
21133 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
21134 That way, the code declares only the vars that it needs.

21146 Define only if needed.
21148 * unexelf.c (unexec): Name an expression,
21149 to avoid gcc -Wbad-function-cast warning.
21150 Use a different way to cause a compilation error if anyone uses
21151 n rather than nn, a way that does not involve shadowing.
21152 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21154 * deps.mk (unexalpha.o): Remove; unused.
21156 New file unexec.h, the (simple) interface for unexec (Bug#8267).

21277 (RETALLOC_IF): Define only if needed.
21278 (WORDCHAR_P): Likewise. This one is never needed, but is used
21279 only in a comment talking about a compiler bug, so put inside
21280 the #if 0 of that comment.

21308 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
21309 New macros, so that the caller can use some names other than
21310 gcpro1, gcpro2, etc.
21311 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
21313 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
21314 argument, for consistency with GCPRO2_VAR, etc: it is now the
21315 prefix of the variable, not the variable itself. All uses
21317 * dired.c (directory_files_internal, file_name_completion):
21318 Rename locals to avoid shadowing.
21320 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
21321 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
21322 dired.c's scmp function, had undefined behavior.

21324 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
21325 * buffer.h: ... to here, because these macros use current_buffer,
21326 and the new implementation with inline functions needs to have
21327 current_buffer in scope now, rather than later when the macros
21329 (downcase, upcase1): New static inline functions.
21330 (DOWNCASE, UPCASE1): Reimplement using these functions.
21331 This avoids undefined behavior in expressions like

21383 to suppress a gcc -Wclobbered warning that does not seem to be right.
21384 (MAXPATHLEN): Define only if needed.
21386 * process.c (serial_open, serial_configure): Move decls from here ...
21387 * systty.h: ... to here, so that they can be checked.

21746 -Wuninitialized does not deduce are never used uninitialized.
21747 (detect_coding_iso_2022): Initialize a local variable that might
21748 be used uninitialized. Leave a FIXME because it's not clear that
21749 this initialization is needed. (Bug#8211)
21750 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
21751 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):

21754 Remove unused macros.
21756 * category.c (hash_get_category_set): Remove unused local var.
21757 (copy_category_table): Now static, since it's not used elsewhere.

21782 Move these decls to tparam.h, and make them agree with what
21783 is actually in tparam.c. The previous trick of using incompatible
21784 decls in different modules does not conform to the C standard.
21785 All callers of tparam changed to use tparam's actual API.
21786 * tparam.c (tparam1, tparam, tgoto):
