52 * insdel.c (move_gap): Remove.
53 (move_gap_both): Add eassert.
54 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.

60 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
62 * term.c (init_tty): Use them instead of rolling our own code.

64 switches from 'signal' to 'pthread_sigmask', which is safer in
65 multithreaded applications.
66 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
67 which has already arranged for that.
68 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
69 This is the main part of the bug fix.

90 Use Qstringp for default-directory, buffer-file-name,
91 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
92 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for

112 * coding.c (coding_alloc_by_making_gap): Use it.
113 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
114 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
116 2013-01-08 Juri Linkov <juri@jurta.org>
118 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
119 of (supports :underline (:style wave)). (Bug#13000)

137 trailing dash is properly added.
139 2013-01-05 Eli Zaretskii <eliz@gnu.org>
141 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
142 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
143 digits for buffer positions, before misalignment starts.
144 Display "0" for integer "object" field.
145 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
146 Display the newline glyph more unambiguously.
148 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
150 * nsterm.m (ns_draw_underwave):
151 * w32term.c (w32_draw_underwave):
152 * xterm.c (x_draw_underwave): Make underwave look more triangular
153 and also degrade gracefully for small fonts. (Bug#13000)
155 * nsterm.m (ns_draw_text_decoration):
156 * w32term.c (x_draw_glyph_string):
157 * xterm.c (x_draw_glyph_string): Don't use previous underline
158 thickness and position if previous underline type is underwave.
160 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
162 * fileio.c (Ffile_acl): Undocument return format.
164 2013-01-02 Glenn Morris <rgm@gnu.org>
166 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
168 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>
171 * dired.c (file_name_completion):
172 * doc.c (get_doc_string):

177 * minibuf.c (Ftry_completion):
178 * term.c (tty_ins_del_lines):
179 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
180 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
182 2012-12-31 Eli Zaretskii <eliz@gnu.org>
184 * w32.c (unsetenv): Set up the string passed to _putenv
186 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
187 for the bug this caused.
189 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
191 * coding.c (Qmac): Now static.
193 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
195 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
196 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
197 handlebox_widget. Set toolbar_in_hbox to false/true, set
198 toolbar_is_packed to true.
199 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
200 (update_frame_tool_bar): Check toolbar_is_packed for packing.

204 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
205 Check toolbar_is_packed.
206 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
207 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
208 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
210 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
211 (xg_update_menubar): Update title only if
212 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
213 (xg_update_submenu): Skip tearoff only if
214 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
215 (xg_initialize): Initialize xg_detached_menus only if
216 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
218 * xterm.h (struct x_output): Surround handlebox_widget with
219 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,

222 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
224 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
225 (LIBS_GNUSTEP): Define.
226 (LIBES): Add $(LIBS_GNUSTEP).

229 2012-12-30 Eli Zaretskii <eliz@gnu.org>
231 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
232 continuation glyph on a TTY with an indication of an empty line.
235 2012-12-29 Eli Zaretskii <eliz@gnu.org>
237 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
238 file's SELinux context or ACLs successfully set, nil otherwise.
240 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
242 * w32proc.c (reader_thread): Avoid passing NULL handles to
243 SetEvent and WaitForSingleObject.
245 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
247 Port EXTERNALLY_VISIBLE to Clang 3.2.
248 * conf_post.h (__has_attribute): New macro.
249 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
251 2012-12-27 Glenn Morris <rgm@gnu.org>
253 * cygw32.c (Fcygwin_convert_file_name_to_windows)

256 2012-12-27 Eli Zaretskii <eliz@gnu.org>
258 * fileio.c (file_name_as_directory, directory_file_name):
259 Accept an additional argument MULTIBYTE to indicate whether the input C
260 came from a multibyte or a unibyte Lisp string; all callers
261 adjusted. Don't assume the input string is always multibyte.
263 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
264 don't ENCODE_FILE them, and return a unibyte string if the input
266 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
267 don't assume the input strings will always be multibyte. If the
268 input strings are multibyte, decode strings obtained from C

273 * lisp.h (toplevel): Add two notices to the comment about
274 defining a new Lisp data type.
275 * print.c (print_object): If Lisp_Save_Value object's pointer
276 is the address of a memory area containing Lisp_Objects, try
278 * alloc.c (valid_lisp_object_p): Adjust comment.
280 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
282 * keyboard.c (record_asynch_buffer_change): Initialize an event
283 only if it's really needed.
284 * frame.h (enum output_method): Remove output_mac member since
285 it's a leftover from the deleted code.
286 * frame.c (Fframep): Adjust user here ...
287 * terminal.c (Fterminal_live_p): ... and here.
288 * coding.c (Qmac): Now here because it's only used to denote
289 end-of-line encoding type.
290 (syms_of_coding): DEFSYM it.
291 * frame.h (Qmac): Remove duplicated declaration.
293 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
295 * window.c (select_window_1): Now static, since it's used only here.
297 2012-12-25 Eli Zaretskii <eliz@gnu.org>
299 * window.c (window_body_cols): Subtract display margins from the
300 window body width on TTYs as well. See
301 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
302 for the original report.
304 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
306 * xdisp.c (redisplay_window): Remove inner local variable
307 because the outer shadowed one has the same meaning.
308 * xterm.h (struct x_output): Remove toolbar_detached member since it's
310 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
311 (xg_create_tool_bar): Adjust users.
313 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
315 * buffer.h (BUF_COMPACT): New macro to follow the common style.
316 * buffer.c (Fget_buffer_create): Use it to set compact field of
317 struct buffer_text to avoid accessing an uninitialized value
318 when compact_buffer is called for the first time.
319 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
320 (Fset_buffer_modified_p): Use buffer_window_count to check
321 whether the buffer is displayed in some window.
322 * xdisp.c (message_dolog): Likewise.
324 2012-12-23 Eli Zaretskii <eliz@gnu.org>
326 * w32.c (acl_set_file): If setting the file security descriptor
327 fails, and the new DACL is identical to the existing one, silently
328 return success. This fixes problems for users backing up their
329 own files without having the necessary privileges for setting
330 security descriptors.
332 * w32proc.c (reader_thread): Do not index fd_info[] with negative
334 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
335 after WaitForSingleObject returns normally. This expedites reader
336 thread shutdown when delete_child triggers it.
337 (reap_subprocess): More accurate commentary for why we call
338 delete_child only when cp->fd is negative.
340 * w32.c (sys_close): Do not call delete_child on a subprocess
341 whose handle is not yet closed. Instead, set its file descriptor
342 to a negative value, so that reap_subprocess will call
343 delete_child on that subprocess when its SIGCHLD arrives.
344 This avoids closing handles used for communications between sys_select
345 and reader_thread, which doesn't give sys_select a chance to
346 notice that the process exited and invoke the SIGCHLD handler for
349 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
351 * nsfns.m (Fns_do_applescript): Run event loop until script has
352 been executed (Bug#12969).
353 (ns_run_ascript): Chech as_script for nil, set to nil after
356 2012-12-22 Martin Rudalics <rudalics@gmx.at>

362 * w32term.c (w32fullscreen_hook): New function.
363 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
365 2012-12-21 Eli Zaretskii <eliz@gnu.org>
367 * fileio.c (Finsert_file_contents): Doc fix.
369 * w32proc.c (new_child, delete_child, find_child_pid): For a
370 subprocess, consider its slot being in use as long as its process
371 handle (procinfo.hProcess) is not NULL. This avoids reusing the
372 slot when a new process is started immediately after killing
373 another one, without waiting enough time for the first process to
374 be reaped and resources allocated for it be orderly freed.
376 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
378 2012-12-21 Chong Yidong <cyd@gnu.org>
380 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
382 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
384 2012-12-21 Eli Zaretskii <eliz@gnu.org>
386 * w32.c (get_name_and_id): Always pass NULL as the first argument
387 of lookup_account_sid. Avoids crashes with UNC file names that
388 refer to DFS domains, not to specific machine names. (Bug#12621)
389 Remove now unused argument FNAME; all callers changed.
390 (get_file_owner_and_group): Remove now unused argument FNAME; all
393 2012-12-21 Chong Yidong <cyd@gnu.org>
395 * editfns.c (Finsert_char): Since read-char-by-name now signals an
396 error for invalid chars, don't check for a nil return value.
398 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
400 Avoid calls to CHAR_TO_BYTE if byte position is known.
401 * editfns.c (make_buffer_string_both): Use move_gap_both.
402 (Fbuffer_string): Use make_buffer_string_both.
403 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
405 (buf_bytepos_to_charpos): Likewise.

407 * fileio.c (Finsert_file_contents): Use move_gap_both.
408 * search.c (Freplace_match): Likewise.
409 * process.c (process_send_region): Likewise. Use convenient
410 names for byte positions.
411 * lisp.h (charpos_to_bytepos): Remove prototype.
412 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
413 * insdel.c (move_gap): Likewise.

423 proper value of frame-local variables (bug#13225).
425 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
427 * textprop.c (set_text_properties_1): Do not allow NULL interval.
428 Rename 4th argument since it may be buffer or string. Adjust comment.
429 * intervals.c (graft_intervals_info_buffer): Find an interval here.
431 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
433 * coding.c (Fdetect_coding_region): Do not check start and end with
434 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
435 (code_convert_region): Likewise.
437 2012-12-18 Eli Zaretskii <eliz@gnu.org>
439 * w32.c (acl_get_file, acl_set_file): Run the file name through
440 map_w32_filename, and resolve any symlinks in the file name, like
442 (acl_set_file): Call revert_to_self, if any privileges were
445 2012-12-17 Juanma Barranquero <lekktu@gmail.com>

448 ($(BLD)/w32.$(O)): Update dependencies.
450 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
452 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
453 propagate redisplay's scrolling (if any) to the right window.
454 (redisplay_internal): Use ensure_selected_frame.
455 (display_mode_lines): Complete last fix.
456 * window.c (select_window_1): New func, extracted from select_window.
457 (select_window): Use it.
458 * window.h (select_window_1): Declare.

484 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
486 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
487 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
488 for some of that bug's symptoms can now cause Emacs to abort.
489 Remove the workaround.
490 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
491 The bug that caused SIGCHLD to get lost has been fixed, and the
492 workaround for it can now cause Emacs to abort.
494 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>

500 2012-12-16 Romain Francoise <romain@orebokech.com>
502 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
503 (Fcopy_file): Change last arg to `preserve_extended_attributes'
504 and copy ACL entries of file in addition to SELinux context if set.
505 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
507 * Makefile.in (LIBACL_LIBS): New macro.
510 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
512 * fileio.c (internal_delete_file): Use bool for boolean.
514 2012-12-15 Eli Zaretskii <eliz@gnu.org>
516 Fix bug #13079 on MS-Windows with temp files not being deleted.
517 * w32.h (_child_process): New members input_file and
519 (register_child): First argument is now pid_t.
520 (record_infile, record_pending_deletion): New prototypes.
522 * w32proc.c (new_child): Initialize input_file and
523 pending_deletion members of the child.
524 (delete_child): Delete the child's temporary input file, if any,
525 that is pending deletion.
526 (register_child): First argument is now pid_t.
527 (record_infile, record_pending_deletion): New functions.
528 (reap_subprocess): Fix a typo in DebPrint string.
529 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
531 * fileio.c (internal_delete_file): Return an int again: non-zero
532 if delete-file succeeds, zero otherwise.
534 * lisp.h (internal_delete_file): Adjust prototype.
536 * callproc.c (Fcall_process): Don't overwrite infile with result
538 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
539 asynchronous subprocess, record the name of the input file name,
541 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
542 delete the file, record it as pending deletion when the subprocess
545 2012-12-14 Eli Zaretskii <eliz@gnu.org>
547 * editfns.c [HAVE_PWD_H]: Include grp.h.
549 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.

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

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

567 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
568 try to get accurate owner and group information from NT file
569 security APIs. This is to make most callers of 'stat' and
570 'lstat', which don't need that information, much faster.
572 * dired.c (Ffile_attributes) [WINDOWSNT]:
573 Set w32_stat_get_owner_group to a non-zero value, to request accurate
574 owner and group information from 'lstat'.
576 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
578 * fileio.c (Finsert_file_contents): Don't put tail into head area,
579 as that confuses set-auto-coding, so insist on the head-read
580 returning the full 1024 bytes. Let lseek compute the tail offset;
581 less work for us. Do not ignore I/O errors when reading the tail.

604 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
605 files, fixing a regression from 24.2.
606 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
608 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
610 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
611 fstat shouldn't fail, and if it does fail copy-file should not proceed.
612 Remove unnecessary S_ISLNK test, as (contra the comments) this
613 function can't copy symlinks. Improve quality of error message
614 when attempting to copy files that are neither regular files nor

633 * inotify.c (inotify_callback): Generate an Emacs event for every
634 incoming inotify event.
636 2012-12-11 Eli Zaretskii <eliz@gnu.org>
638 * xdisp.c (handle_face_prop): Fix logic of computing
639 it->start_of_box_run_p.
640 (append_space_for_newline): If the glyph row is R2L, reset the
641 iterator's end_of_box_run_p flag before prepending the space glyph.
642 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
643 iterator's start_of_box_run_p flag before prepending the stretch.
644 (append_glyph, produce_image_glyph, append_composite_glyph)
645 (append_stretch_glyph, append_glyphless_glyph): Reverse the
646 left_box_line_p and right_box_line_p flags of the glyph for R2L
647 glyph rows. (Bug#13011)

659 2012-12-11 Eli Zaretskii <eliz@gnu.org>
661 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
662 encoded_file_name, which is what it is.

697 (hinst): Remove unneeded extern declaration.
698 (_start): Remove initialization of above variables; remove
699 initialization of hinst, as cache_system_info now does that.
701 * emacs.c (main): Call cache_system_info early in startup; we
702 previously weren't calling it in Cygwin builds.

970 fails, signal an error instead of continuing with an empty
972 Encode expanded temp file pattern before passing it to mkstemp or
975 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
976 Encode the file name before passing it to dostounix_filename, in
977 case it will downcase it (under w32-downcase-file-names).
980 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
982 Minor call-process cleanups.
983 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
984 at the same time as other platforms, to simplify analysis.
985 No need for fd0_volatile since we have synch_process_fd.
986 Avoid needless emacs_close; arg is always negative.
988 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
990 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
993 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>

996 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
997 and mouse_face_hidden members to a bitfields.
998 * frame.h (struct frame): Remove set-but-not-used space_width member.
999 (FRAME_SPACE_WIDTH): Remove.
1000 * nsterm.m, w32term.c, xterm.c: Adjust users.
1001 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
1002 member. Adjust users. Convert term_initted, delete_in_insert_mode,
1003 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
1004 members to a bitfields.
1006 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
1008 Don't let call-process be a zombie factory (Bug#12980).
1009 Fixing this bug required some cleanup of the signal-handling code.
1010 As a side effect, this change also fixes a longstanding rare race
1011 condition whereby Emacs could mistakenly kill unrelated processes,
1012 and it fixes a bug where a second C-g does not kill a recalcitrant
1013 synchronous process in GNU/Linux and similar platforms.
1014 The patch should also fix the last vestiges of Bug#9488,
1015 a bug which has mostly been fixed on the trunk by other changes.
1016 * callproc.c, process.h (synch_process_alive, synch_process_death)
1017 (synch_process_termsig, sync_process_retcode):
1018 Remove. All uses removed, to simplify analysis and so that
1019 less consing is done inside critical sections.
1020 * callproc.c (call_process_exited): Remove. All uses replaced
1021 with !synch_process_pid.
1022 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1023 These take the role of what used to be in unwind-protect arg.
1025 (block_child_signal, unblock_child_signal):
1026 New functions, to avoid races that could kill innocent-victim processes.
1027 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1028 (call_process_kill): Record killed processes as deleted, so that
1029 zombies do not clutter up the system. Do this inside a critical
1030 section, to avoid a race that would allow the clutter.
1031 (call_process_cleanup): Fix code so that the second C-g works again
1032 on common platforms such as GNU/Linux.
1033 (Fcall_process): Create the child process in a critical section,
1034 to fix a race condition. If creating an asynchronous process,
1035 record it as deleted so that zombies do not clutter up the system.
1036 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1037 light of these changes. Omit unnecessary call to emacs_close
1038 before failure, as the unwind-protect code does that.
1039 * callproc.c (call_process_cleanup):
1040 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1041 * process.c (record_deleted_pid): New function, containing
1042 code refactored out of Fdelete_process.
1043 (Fdelete_process): Use it.
1044 (process_status_retrieved): Remove. All callers changed to use
1045 child_status_change.
1046 (record_child_status_change): Remove, folding its contents into ...
1047 (handle_child_signal): ... this signal handler. Now, this
1048 function is purely a handler for SIGCHLD, and is not called after
1049 a synchronous waitpid returns; the synchronous code is moved to
1050 wait_for_termination. There is no need to worry about reaping
1051 more than one child now.
1052 * sysdep.c (get_child_status, child_status_changed): New functions.
1053 (wait_for_termination): Now takes int * status and bool
1054 interruptible arguments, too. Do not record child status change;
1055 that's now the caller's responsibility. All callers changed.
1056 Reimplement in terms of get_child_status.
1057 (wait_for_termination_1, interruptible_wait_for_termination):
1058 Remove. All callers changed to use wait_for_termination.
1059 * syswait.h: Include <stdbool.h>, for bool.
1060 (record_child_status_change, interruptible_wait_for_termination):
1062 (record_deleted_pid, child_status_changed): New decls.
1063 (wait_for_termination): Adjust to API changes noted above.
1065 * bytecode.c, lisp.h (Qbytecode): Remove.
1066 No longer needed after 2012-11-20 interactive-p changes.
1068 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1070 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1071 the scroll margin, move point outside the margin. (Bug#13055)

1080 * lisp.h (modify_region): Rename to...
1081 (modify_region_1): ...new prototype.
1082 * textprop.c (modify_region): Now static. Adjust users.
1083 * insdel.c (modify_region): Rename to...
1084 (modify_region_1): ...new function to work with current buffer.
1085 Adjust comment and users. Use true and false for booleans.
1087 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1089 * alloc.c (free_save_value): New function.
1090 (safe_alloca_unwind): Use it.
1091 * lisp.h (free_save_value): New prototype.
1092 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1094 (save_excursion_restore): Adjust to match saved data structure.
1095 Use free_save_value to offload some work from GC. Drop obsolete
1098 2012-12-03 Chong Yidong <cyd@gnu.org>
1100 * fileio.c (Vauto_save_list_file_name): Doc fix.
1102 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1104 * w32fns.c: Remove prototype of atof.
1105 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1107 (file_dialog_callback): Make it UINT_PTR.
1109 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1112 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1113 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1116 2012-12-03 Glenn Morris <rgm@gnu.org>
1118 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1120 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1122 Fix xpalloc confusion after memory is exhausted.
1123 * alloc.c (xpalloc): Comment fix.
1124 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1125 and signals an error, do not clear charset_table_size, as
1126 charset_table is still valid.
1127 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1129 Use execve to avoid need to munge environ (Bug#13054).
1130 * callproc.c (Fcall_process):
1131 * process.c (create_process):
1132 Don't save and restore environ; no longer needed.
1133 * callproc.c (child_setup):
1134 Use execve, not execvp, to preserve environ.
1136 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1138 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1140 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1142 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1143 display for sliced images (Bug#10500).
1145 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1147 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1149 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1150 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1152 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1154 * xdisp.c (window_outdated): Remove eassert since it hits
1155 some suspicious corner cases (see Bug#13007 and Bug#13012).
1156 (mode_line_update_needed): New function.
1157 (redisplay_internal, redisplay_window): Use it.
1158 (ensure_selected_frame): New function.
1159 (redisplay_internal, unwind_redisplay): Use it.
1160 (redisplay_internal): Move comment about buffer_shared...
1161 (buffer_shared_and_changed): ...near to its real use.
1163 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1165 * callproc.c (Fcall_process): Don't misreport vfork failure.
1167 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1169 * callproc.c (Fcall_process): Fix vfork portability problems.
1170 Do not assume that fd[0], count, filefd, and save_environ survive
1171 vfork. Fix bug whereby wrong errno value could be reported for
1172 pipe failure. Some minor cleanups, too, as follows. Move buf and
1173 bufsize to the context where they're needed. Change new_argv to
1174 be of type char **, as this is more convenient and avoids casts.
1175 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1176 Now local constants, not macros.
1178 2012-11-18 Kenichi Handa <handa@gnu.org>
1180 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1181 for the variable "f".
1183 2012-11-13 Kenichi Handa <handa@gnu.org>
1185 * font.c (font_unparse_xlfd): Exclude special characters from the
1186 generating XLFD name.
1188 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

1213 violations when repeatedly clicking on the "Top" link of the
1214 "bread-crumbs" in Info buffers.

1228 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1229 between bpos_covered and bpos_max. This fixes cursor display when
1230 several display strings follow each other.
1232 * .gdbinit (pgx): If the glyph's object is a string, display the
1233 pointer to string data, rather than the value of the string object
1234 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1236 * indent.c (Fvertical_motion): If the starting position is covered
1237 by a display string, return to one position before that, to avoid
1238 overshooting it inside move_it_to. (Bug#12930)
1240 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

1259 of a literal "/". (Bug#12955)
1260 (gl-stamp): Invoke fc.exe directly, not through cmd.

1264 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
1265 * dired.c: Assume HAVE_DIRENT_H.
1266 (NAMLEN): Remove, replacing with ...
1267 (dirent_namelen): New function. All uses changed. Use the GNU macro
1268 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1269 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1270 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1271 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1273 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1274 * ndir.h: Rename to ../nt/inc/dirent.h.
1275 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1276 Do not include <dirent.h>; no longer needed.
1277 * w32.c: Include <dirent.h> rather than "ndir.h".
1279 2012-11-23 Chong Yidong <cyd@gnu.org>
1281 * xftfont.c (xftfont_open): Remove duplicate assignment.
1283 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1285 * alloc.c (Fgarbage_collect): Unblock input after clearing
1286 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1287 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1288 * msdos.c (IT_frame_up_to_date): Use it here...
1289 * w32term.c (w32_frame_up_to_date): ...here...
1290 * xterm.c (XTframe_up_to_date): ...and here...

1305 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1307 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts

1333 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1335 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1336 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1337 Define for the MSVC compiler.
1339 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.

1344 dostounix_filename assumes it gets a unibyte string.
1345 Reported by Michel de Ruiter <michel@sentient.nl>, see

1394 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1396 * w32select.c: Include w32common.h before w32term.h, so that
1397 windows.h gets included before w32term.h uses some of its
1398 features, see below.
1400 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1402 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

1416 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1418 * w32proc.c (waitpid): Remove unused label get_result.

1430 * emacs.c, term.c (O_RDWR): Remove.
1431 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than

1435 (create_pty, Fmake_network_process, server_accept_connection)

1440 It's not clear this is needed, but it's a more-conservative change.
1441 (create_process): Assume FD_CLOEXEC.
1442 (create_process, create_pty): Assume O_NOCTTY.
1443 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.

1447 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1449 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1450 lack it, since gnulib guarantees this.
1451 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1453 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1455 * w32.c (faccessat): Pretend that directories have the execute bit
1456 set. Emacs expects that, e.g., in files.el:cd-absolute.
1458 * w32proc.c (create_child): Don't clip the PID of the child
1459 process to fit into an Emacs integer, as this is no longer a
1461 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1462 reaping only the process specified by PID argument, if that is
1463 positive. Use PID instead of dead_child to know which process to
1464 reap. Wait for the child to die only if WNOHANG is not in
1466 (sys_select): Don't set dead_child.
1468 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1469 as it is no longer needed.
1471 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1473 (record_child_status_change): Remove the setting of
1474 record_at_most_one_child for the !WNOHANG case.
1476 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1478 Fix problems in ns port found by static checking.
1479 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1480 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1481 not to process group.
1482 (ns_select): Use emacs_write, not write, as that's more robust
1483 in the presence of signals.
1484 (fd_handler:): Check for read errors.
1486 2012-11-16 Glenn Morris <rgm@gnu.org>
1488 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1490 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1492 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1494 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1496 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1497 use the same value of thread handle.
1498 (start_timer_thread): If the timer thread exited (due to error),
1499 clean up by closing the two handles it used. Duplicate the caller
1500 thread's handle here, so it gets duplicated only once, when
1501 launching the timer thread. Set priority of the timer thread, not
1503 (getitimer): Don't duplicate the caller thread's handle here.
1506 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1508 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1511 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1513 Remove no-longer-used pty_max_bytes variable.
1514 * process.c (pty_max_bytes): Remove; unused.
1515 (send_process): Do not set it.
1517 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1519 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1520 Update dependencies.
1522 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1524 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1525 This follows up on the 2012-09-29 patch that removed indirection
1526 for the 'function' field. Reported by Sergey Vinokurov in
1527 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1529 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1531 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1532 different name, as the MS runtime does not have such a function,
1533 and probably never will.) All callers changed. Ignore DIRFD
1534 value if PATH is an absolute file name, to match Posix spec
1535 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1538 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1540 * xdisp.c (echo_area_display, redisplay_internal):
1541 Omit redundant check whether frame_garbaged is set.
1543 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1545 Use faccessat, not access, when checking file permissions (Bug#12632).
1546 This fixes a bug that has been present in Emacs since its creation.
1547 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1548 which must set some sort of record. (Torek's bug report was against
1549 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1550 same common flaw.) See Torek's Usenet posting
1551 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1552 Posted: Fri Apr 8 14:18:56 1983.
1553 * Makefile.in (LIB_EACCESS): New macro.
1555 * callproc.c (init_callproc):
1556 * charset.c (init_charset):
1557 * fileio.c (check_existing, check_executable, check_writable)
1559 * lread.c (openp, load_path_check):
1560 * process.c (allocate_pty):
1562 Use effective UID when checking permissions, not real UID.
1563 * callproc.c (init_callproc):
1564 * charset.c (init_charset):
1565 * lread.c (load_path_check, init_lread):
1566 Test whether directories are accessible, not merely whether they exist.
1567 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1568 * fileio.c (check_existing, check_executable, check_writable)
1570 Use symbolic names instead of integers for the flags, as they're
1572 (check_writable): New arg AMODE. All uses changed.
1573 Set errno on failure.
1574 (Ffile_readable_p): Use faccessat, not stat + open + close.
1575 (Ffile_writable_p): No need to call check_existing + check_writable.
1576 Just call check_writable and then look at errno. This saves a syscall.
1577 dir should never be nil; replace an unnecessary runtime check
1578 with an eassert. When checking the parent directory of a nonexistent
1579 file, check that the directory is searchable as well as writable, as
1580 we can't create files in unsearchable directories.
1581 (file_directory_p): New function, which uses 'stat' on most platforms
1582 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1583 (Ffile_directory_p, Fset_file_times): Use it.
1584 (file_accessible_directory_p): New function, which uses a single
1585 syscall for efficiency.
1586 (Ffile_accessible_directory_p): Use it.
1587 * xrdb.c (file_p): Use file_directory_p.
1588 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1589 * lread.c (openp): When opening a file, use fstat rather than
1590 stat, as that avoids a permissions race. When not opening a file,
1591 use file_directory_p rather than stat.
1592 (dir_warning): First arg is now a usage string, not a format.
1593 Use errno. All uses changed.
1594 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1595 that merely introduced a race.
1596 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1597 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1598 and similarly for the other O_* flags.
1599 * w32.c (sys_faccessat): Rename from sys_access and switch to
1600 faccessat's API. All uses changed.
1601 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1602 (magic_db): Rename from magic_file_p.
1603 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1604 char *, so that we don't have to test for file existence
1605 separately from opening the file for reading. This removes a race
1606 fixes a permission-checking problem, and simplifies the code.
1608 (file_p): Remove; no longer needed.
1610 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1612 Omit glyphs initialization at startup.
1613 * dispnew.c (glyphs_initialized_initially_p): Remove.
1614 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1615 (Fredraw_frame): Move actual code from here...
1616 (redraw_frame): ...to here. Add eassert. Adjust comment.
1617 (Fredraw_display): Use redraw_frame.
1618 * xdisp.c (clear_garbaged_frames): Likewise.
1620 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1622 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1623 passed to pint2str and pint2hrstr to be at most the size of the
1624 frame's decode_mode_spec_buffer. This avoids crashes with very
1625 large values of FIELD_WIDTH argument to decode_mode_spec.
1628 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1630 Fix a race with verify-visited-file-modtime (Bug#12863).
1631 Since at least 1991 Emacs has ignored an mtime difference of no
1632 more than one second, but my guess is that this was to work around
1633 file system bugs that were fixed long ago. Since the race is
1634 causing problems now, let's remove that code.
1635 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1636 whose time stamp is off by no more than a second. Insist that the
1637 file time stamps match exactly.
1639 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1641 * frame.h (struct frame): Convert external_tool_bar member to
1642 1-bit unsigned bitfield.
1643 * termhooks.h (struct terminal): Remove mouse_moved member since
1644 all users are long dead. Adjust comment on mouse_position_hook.
1646 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1648 Simplify by using FOR_EACH_FRAME here and there.
1649 * frame.c (next_frame, prev_frame, other_visible_frames)
1650 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1651 * w32term.c (x_window_to_scroll_bar): Likewise.
1652 * window.c (window_list): Likewise.
1653 * xdisp.c (x_consider_frame_title): Likewise.
1654 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1655 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1656 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1657 * xmenu.c (menubar_id_to_frame): Likewise.
1658 * xselect.c (frame_for_x_selection): Likewise.
1659 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1660 (x_window_to_menu_bar): Likewise.
1661 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1663 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1665 * data.c (Qdefalias_fset_function): Now static.
1667 Another tweak to vectorlike_header change.
1668 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1669 Remove, and replace all uses with ...
1670 (next_in_free_list, set_next_in_free_list):
1671 New functions, which respect C's aliasing rules better.
1673 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1675 * window.c (list4i): Rename from 'quad'. All uses changed.
1676 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1678 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1680 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1681 warning about mixing declarations and code in ISO C90.
1683 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1685 * window.c (Fsplit_window_internal): Set combination limit of
1686 new parent window to t iff Vwindow_combination_limit is t;
1687 fixing a regression introduced with the change from 2012-09-22.
1688 (Fset_window_combination_limit): Fix doc-string.
1690 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1692 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1693 amount when the scroll margins are too large. When scrolling
1694 backwards in the buffer, give up if cannot reach point or the
1695 scroll margin within a reasonable number of screen lines.
1696 Fixes point position in window under scroll-up/down-aggressively when
1697 point is positioned many lines beyond the window top/bottom.
1700 * ralloc.c (relinquish): If real_morecore fails to return memory
1701 to the system, don't crash; instead, leave the last heap
1702 unchanged and return. (Bug#12774)
1704 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1706 * lisp.h (AUTOLOADP): New macro.
1707 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1708 * data.c (Ffset): Remove special ad-advice-info handling.
1709 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1711 (Finteractive_form): Simplify.
1712 (Fquo): Don't insist on having at least 2 arguments.
1713 (Qdefalias_fset_function): New var.
1715 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1717 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
1719 * nsfont.m (Qcondensed, Qexpanded): New variables.
1720 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
1721 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
1723 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1725 Fix recently introduced crash on MS-Windows (Bug#12839).
1726 * w32term.h (struct scroll_bar): Use convenient header.
1727 (SCROLL_BAR_VEC_SIZE): Remove.
1728 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1730 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1732 Tweak last vectorlike_header change.
1733 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1734 vectorlike object on the free list. This is introduced to avoid
1735 some (but not all) pointer casting and aliasing problems, see
1736 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1737 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1739 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1741 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1743 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1744 been removed, so remove them here also.
1746 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1748 * doc.c (Fdocumentation): Handle new property
1749 dynamic-docstring-function to replace the old ad-advice-info.
1751 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1753 * fns.c (Qeql, hashtest_eq): Now static.
1755 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1757 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1758 * fns.c (hashfn_eq, hashfn_eql, sxhash):
1759 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
1760 * buffer.c (compare_overlays): Use XLI rather than XHASH.
1762 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
1764 Use same hash function for hashfn_profiler as for hash_string etc.
1765 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1766 * lisp.h (sxhash_combine): New inline function, with the contents
1767 of the old SXHASH_COMBINE.
1768 * profiler.c (hashfn_profiler): Use it, instead of having a
1769 special hash function containing a comparison that always yields 1.
1771 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1773 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1774 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1775 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1778 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1780 * image.c (xpm_make_color_table_h): Fix compiler error because
1781 make_hash_table changed.
1783 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1785 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1787 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1789 Use ad-hoc comparison function for the profiler's hash-tables.
1790 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1791 (make_log): Use them.
1792 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1793 call Fequal any more.

1802 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1803 (hash_lookup, hash_remove_from_table): Move assertion checking of
1804 hashfn result here. Check hash-equality before calling cmpfn.
1805 (Fmake_hash_table): Adjust call to make_hash_table.
1806 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
1807 (syms_of_fns): Initialize them.

1811 * print.c (print_object): Adjust to new hash-table struct.
1812 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
1814 2012-11-08 Eli Zaretskii <eliz@gnu.org>
1816 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
1817 value of w32-scroll-lock-modifier is neither nil nor one of the
1818 known key modifiers. (Bug#12806)
1820 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1822 Shrink struct vectorlike_header to the only size field.
1823 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1825 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
1826 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
1827 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
1828 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1829 information from the vector header. Adjust comment.
1830 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
1831 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
1833 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
1834 (struct vectorlike_header): Remove next member. Adjust comment.

1837 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
1838 (sweep_string, lisp_malloc): Remove useless prototypes.
1839 (enum mem_type): Adjust comment.
1840 (NEXT_IN_FREE_LIST): New macro.
1841 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1842 (Fmake_bool_vector): Likewise.
1843 (struct large_vector): New type to represent allocation unit for
1844 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1845 (large_vectors): Change type to struct large_vector.
1846 (allocate_vector_from_block): Simplify.
1847 (PSEUDOVECTOR_NBYTES): Replace with...
1848 (vector_nbytes): ...new function. Adjust users.
1849 (sweep_vectors): Adjust processing of large vectors.
1850 (allocate_vectorlike): Likewise.
1851 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
1852 Add easserts. Adjust XSETPVECTYPESIZE usage.
1853 (allocate_buffer): Use BUFFER_PVEC_INIT.
1854 (live_vector_p): Adjust to match large vector.
1855 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1856 * buffer.h (struct buffer): Add next member.
1857 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1859 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
1860 * fns.c (internal_equal): Adjust to match enum pvec_type change.
1861 (copy_hash_table): Adjust to match vector header change.
1862 * lread.c (defsubr): Use XSETPVECTYPE.
1863 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
1864 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
1865 (xvecsize): New command.
1867 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1869 * keyboard.c (event_to_kboard): Do not dereference
1870 frame_or_window field of SELECTION_REQUEST_EVENT
1871 and SELECTION_CLEAR_EVENT events (Bug#12814).
1872 * xterm.h (struct selection_input_event): Adjust comment.
1874 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1876 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1877 such as Scroll Lock, if the respective keys are treated as
1878 function keys, not as modifiers. This avoids destroying non-ASCII
1879 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1881 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1883 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1885 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1887 Restore some duplicate definitions (Bug#12814).
1888 This undoes part of the 2012-11-03 changes. Some people build
1889 with plain -g rather than with -g3, and they need the duplicate
1890 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1891 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1892 Define as macros, as well as as enums or as constants.
1894 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1896 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1897 to keypad keys (Bug#12816).
1899 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1901 Minor adjustments of recently-changed frame functions.
1902 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1903 known to be a frame (we're in the FRAMEP branch).
1904 * lisp.h (Qframep): Remove decl. frame.h declares this.
1905 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1906 since they're meant for Lisp fixnum values.
1908 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1910 * window.c (Fwindow_combination_limit): Revert to the only
1911 required argument and adjust docstring as suggested in
1912 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1913 by Martin Rudalics <rudalics@gmx.at>.
1915 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1917 Widely used frame validity and checking functions.
1918 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1919 * frame.c (decode_live_frame, decode_any_frame): New functions.
1920 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
1921 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
1922 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
1923 (Fframe_pointer_visible_p): Use decode_any_frame.
1924 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
1925 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
1926 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
1927 (Fframe_focus): Likewise. Allow zero number of arguments.
1929 (frame_buffer_list, frame_buffer_predicate): Remove.
1930 * lisp.h (frame_buffer_predicate): Remove prototype.
1931 * buffer.c (Fother_buffer): Use decode_any_frame.
1932 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1933 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1934 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1935 (Fclose_font, Ffont_info): Use decode_live_frame.
1936 * fontset.c (check_fontset_name): Likewise.
1937 * terminal.c (Fframe_terminal): Likewise.
1938 * w32fns.c (check_x_frame): Likewise.
1939 * window.c (Fminibuffer_window, Fwindow_at)
1940 (Fcurrent_window_configuration): Likewise.
1941 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
1942 Likewise. Allow zero number of arguments. Adjust docstring.
1943 * dispnew.c (Fredraw_frame): Likewise.
1944 * xfaces.c (frame_or_selected_frame): Remove.
1945 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1946 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1947 (Fframe_face_alist): Use decode_live_frame.
1948 * xfns.c (check_x_frame): Likewise.
1950 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1952 * window.c (quad): New function.
1953 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1954 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1955 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1956 (Fwindow_line_height): Use it.
1957 (Fwindow_fringes): Use list3.
1958 (Fwindow_scroll_bars): Use list4.
1959 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1960 (Fwindow_combination_limit): Allow zero number of arguments.
1962 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1964 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1966 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1967 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1968 file descriptor 2 for standard error. (Bug#12805)
1970 2012-11-05 Chong Yidong <cyd@gnu.org>
1972 * process.c (wait_reading_process_output): Revert previous change.
1974 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1976 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1977 This removes code that has been obsolete since around 1990.
1978 * callproc.c (Fcall_process):
1980 * process.c (create_process):
1981 * term.c (dissociate_if_controlling_tty):
1982 Assume setsid exists.
1983 * callproc.c (child_setup): Assume setpgid exists and behaves as
1984 per POSIX.1-1988 or later.
1985 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1986 * emacs.c (shut_down_emacs):
1987 * sysdep.c (sys_suspend, init_foreground_group):
1988 Assume getpgrp behaves as per POSIX.1-1998 or later.
1989 * msdos.c (setpgrp): Remove.
1990 (tcgetpgrp, setpgid, setsid): New functions.
1991 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1992 * term.c (no_controlling_tty): Remove; unused.
1993 * w32proc.c (setpgrp): Remove.
1994 (setsid, tcgetpgrp): New functions.
1996 Simplify by assuming __fpending.
1997 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1998 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1999 Do not assume that __fpending's result fits in int.
2001 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2003 Remove EMACS_OUTQSIZE+sleep hack.
2004 * dispnew.c (update_frame_1): Remove hack for terminals slower
2005 than 2400 bps, which throttled Emacs by having it sleep.
2006 This code hasn't worked since at least 2007, when the multi-tty stuff
2007 was added, and anyway those old terminals are long dead.
2008 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2009 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2011 Fix data-loss with --version (Bug#9574).
2012 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2013 as we can't assume that emacs_strerror is initialized, and strerror
2014 is good enough here.
2015 (main): Invoke atexit earlier, to catch earlier instances of
2016 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2018 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2020 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2021 (keyDown): Remap keypad keys to X11 virtual key codes.
2023 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2025 Fix data-loss with --batch (Bug#9574).
2026 * emacs.c: Include <close-stream.h>.
2027 (close_output_streams): New function.
2028 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2029 and handles errors appropriately.
2030 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2033 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2034 The symptom is a diagnostic "GLib-WARNING **: In call to
2035 g_spawn_sync(), exit status of a child process was requested but
2036 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2037 waitpid(), so exit status can't be returned." The diagnostic
2038 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2039 The real bug is a race condition between Emacs and glib: Emacs
2040 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2041 so that glib can't find it. Work around the bug by invoking
2042 waitpid only on subprocesses that Emacs itself creates.
2043 * process.c (create_process, record_child_status_change):
2044 Don't use special value -1 in pid field, as the caller now must
2045 know the pid rather than having the callee infer it.
2046 The inference was sometimes incorrect anyway, due to another race.
2047 (create_process): Set new 'alive' member if child is created.
2048 (process_status_retrieved): New function.
2049 (record_child_status_change): Use it.
2050 Accept negative 1st argument, which means to wait for the
2051 processes that Emacs already knows about. Move special-case code
2052 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2053 processes that have already been waited for, by testing and
2054 clearing new 'alive' member.
2055 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2056 now does this internally.
2057 (handle_child_signal): Let record_child_status_change do all
2058 the work, since we do not want to reap all exited child processes,
2059 only the child processes that Emacs itself created.
2060 * process.h (Lisp_Process): New boolean member 'alive'.
2062 Omit duplicate definitions no longer needed with gcc -g3.
2063 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2064 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2065 Define only as macros. There's no longer any need to also define
2066 these symbols as enums or as constants, since we now assume
2067 gcc -g3 when debugging.
2069 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2071 * lisp.mk: Adjust comments to the fact that term/internal is now
2072 loaded from loadup.el.
2074 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2075 (msdos_fatal_signal): New function.
2076 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2079 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2080 for GCC versions before 4.
2081 (emacs_raise): Define to call msdos_fatal_signal.
2083 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2084 iterator when starting in the middle of a display or overlay
2087 2012-11-03 Chong Yidong <cyd@gnu.org>
2089 * process.c (wait_reading_process_output): Clean up the last
2092 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2094 * process.c (wait_reading_process_output): Avoid a race condition
2095 with SIGIO delivery (Bug#11536).
2097 2012-11-03 Chong Yidong <cyd@gnu.org>
2099 * buffer.c (cursor_type): Untabify docstring.
2101 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2103 * frame.h (struct frame): Drop can_have_scroll_bars member
2104 which is meaningless for a long time. Adjust comments.
2105 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2106 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2108 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2110 * window.c (decode_next_window_args): Update window arg after
2111 calling decode_live_window and so fix crash reported at
2112 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2113 by Juanma Barranquero <lekktu@gmail.com>.
2114 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2115 * font.c (Ffont_at): Likewise.
2117 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2119 * widget.c (resize_cb): New function.
2120 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2121 (EmacsFrameResize): Check if all is up to date before changing frame
2124 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2126 Implement backtrace output for fatal errors on MS-Windows.
2127 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2128 (BACKTRACE_LIMIT_MAX): New macro.
2129 (w32_backtrace): New function.
2130 (emacs_abort): Use w32_backtrace when the user chooses not to
2131 attach a debugger. Update the text of the abort dialog.
2133 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2135 Window-related stuff cleanup here and there.
2136 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2137 Use decode_any_window.
2138 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2139 * xdisp.c (Fformat_mode_line): Likewise.
2140 * font.c (Ffont_at): Use decode_live_window.
2141 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2142 * window.c (decode_next_window_args): Likewise.
2143 (decode_any_window): Remove static.
2144 * window.h (decode_any_window): Add prototype.
2145 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2146 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2149 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2151 Remove pad from struct input_event.
2152 * termhooks.h (struct input_event): Remove padding field.
2154 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2155 member is never cons for a long time. Adjust comment.
2156 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2157 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2158 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2159 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2161 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2163 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2165 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2167 Fix crash when using Emacs as commit editor for git (Bug#12697).
2168 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2169 and it is configured in conf_post.h.
2170 (Fcall_process): Don't invoke both setsid and setpgid; the former
2171 is enough, if it exists.
2172 * callproc.c (Fcall_process, child_setup):
2173 * process.c (create_process): Use setpgid.
2174 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2176 * dispnew.c (init_display): Initialize the foreground group
2177 if we are running a tty display.
2178 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2179 * lisp.h (init_foreground_group): New decl.
2180 * sysdep.c (inherited_pgroup): New static var.
2181 (init_foreground_group, tcsetpgrp_without_stopping)
2182 (narrow_foreground_group, widen_foreground_group): New functions.
2183 (init_sys_modes): Narrow foreground group.
2184 (reset_sys_modes): Widen foreground group.
2186 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2188 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2190 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2192 * minibuf.c (read_minibuf): Restore current buffer since
2193 choose_minibuf_frame calling Fset_frame_selected_window may
2194 change it (Bug#12766).
2196 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2198 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2200 2012-10-30 Kenichi Handa <handa@gnu.org>
2202 * font.c (Ffont_at): If WINDOW is specified and it is not
2203 displaying the current buffer, signal an error.
2205 2012-10-29 Daniel Colascione <dancol@dancol.org>
2207 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2208 In preparation for fixing bug#12739, move these functions from
2211 * coding.h, coding.c: ... to here, and compile them only when
2212 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2213 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2215 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2217 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2218 (timer_loop, getitimer, setitimer): Use it instead of
2219 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2221 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2224 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2226 * nsterm.m (NO_APPDEFINED_DATA): New define.
2227 (last_appdefined_event_data): New variable
2228 (last_appdefined_event): Remove.
2229 (ns_select): Initialize t from last_appdefined_event_data instead
2230 of [last_appdefined_event data1].
2231 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2232 remove last_appdefined_event (Bug#12698).
2234 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2236 * frame.c (x_set_font): Catch internal error.
2238 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2240 Avoid overflow in w32 implementation of interval timers.
2241 When possible, for ITIMER_PROF count only times the main thread
2243 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2244 'volatile ULONGLONG' types. All the other data which was
2245 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2246 (GetThreadTimes_Proc): New typedef.
2247 (w32_get_timer_time): New function, returns a suitable time value
2249 (timer_loop): Enter critical section when accessing ULONGLONG
2250 values of the itimer_data struct, as these accesses are no longer
2251 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2252 Remove unused variable.
2253 (init_timers): Initialize s_pfn_Get_Thread_Times.
2254 (start_timer_thread): Don't assign itimer->caller_thread here.
2255 (getitimer): Assign itimer->caller_thread here.
2256 (setitimer): Always call getitimer to get the value of ticks_now.
2257 (sys_spawnve): Avoid compiler warning about format mismatch.
2259 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2261 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2262 mouse movement events if the menu bar is active. This avoids
2263 producing a busy "hour-glass" cursor by Windows if the mouse
2264 pointer is positioned over a tooltip shown for some menu item.
2266 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2268 Don't assume process IDs fit in int.
2269 * emacs.c (shut_down_emacs) [!DOS_NT]:
2270 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2271 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2272 Use pid_t, not int, to store process IDs, as 'int'
2273 is not wide enough on a few platforms (e.g., AIX and IRIX).
2275 2012-10-23 Kenichi Handa <handa@gnu.org>
2277 The following change is to make face-font-rescale-alist work
2278 correctly for non-ASCII fonts.
2280 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2281 (font_open_for_lface): Handle Vface_font_rescale_alist.
2283 2012-10-23 Chong Yidong <cyd@gnu.org>
2285 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2287 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
2289 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
2291 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2293 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2296 2012-10-21 Glenn Morris <rgm@gnu.org>
2298 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2300 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2302 Port to OpenBSD 5.1.
2303 * frame.c (Fmouse_position, Fmouse_pixel_position):
2304 * xdisp.c (produce_stretch_glyph):
2305 Declare local vars only when they're needed.
2306 This is clearer and avoids a warning on OpenBSD about unused vars.
2307 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2308 This is safer, and avoids OpenBSD warnings about unused vars.
2309 * keyboard.c (record_menu_key): Remove unnecessary decl.
2310 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2311 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2312 as our definition clashes with OpenBSD's.
2313 * xfaces.c (load_face_colors, check_lface_attrs)
2314 (get_lface_attributes_no_remap, get_lface_attributes)
2315 (lface_fully_specified_p, x_supports_face_attributes_p)
2316 (tty_supports_face_attributes_p, face_fontset, realize_face)
2317 (realize_x_face, realize_tty_face):
2318 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2319 merely Lisp_Object *. This is more informative and avoids
2320 a warning on OpenBSD about accessing beyond an object's size.
2322 2012-10-20 Chong Yidong <cyd@gnu.org>
2324 * lread.c (Fload): Doc fix (Bug#12592).
2326 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2328 * font.c (Ffont_at): Fix previous change.
2330 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2332 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2333 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
2336 * alloc.c (NSTATICS): Decrease to 0x800.
2338 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
2340 * fns.c (Fnreverse): Include the problem element when signaling an

2824 compiling for native WINDOWSNT; Cygwin can use shared libraries
2825 like any other Unixlike system.
2827 * keyboard.c: Clarify a comment regarding the input loop.
2829 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2830 functions directly instead of trying to detect at runtime that our
2831 host operating system supports them. We make this change for two
2832 reasons: Cygwin lacks support for the multibyte character
2833 conversion functions used by the legacy menu code, and Cygwin
2834 never needs to rely on non-Unicode APIs.
2836 * unexw32.c (hinst): Declare extern.
2838 * w32.c: Change header order;
2839 (w32_strerror): Move to w32fns.c because we need it for
2840 non-WINDOWSNT builds.
2842 * w32.h: Add #error macro to make sure we don't include w32.h for
2843 Cygwin builds. Remove w32select declarations.
2845 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2846 w32fns.c. w32console.c is WINDOWSNT-only.
2848 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2849 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2851 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2852 (w32_major_version, w32_minor_version, w32_build_number)
2853 (os_subtype, sound_type): Define here
2854 (w32_defined_color): Make color parameter const for consistency
2855 with other _defined_color functions.
2856 (w32_createwindow): Unconditionally call w32_init_class instead of
2857 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2858 through the code is complex and unnecessary because class
2859 registration is practically free.
2860 (w32_name_of_message): New EMACSDEBUG-only function.
2861 (Fset_message_beep): Move here
2862 (Fx_open_connection): Require that the display name for Windows be
2863 "w32" for consistency, emacsclient disambiguation, and maybe, one
2864 day, multi-window-system support.
2865 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2866 Cygwin files for W32 GUI facilities, since these clearly don't
2867 expect Cygwin names.
2868 (_DebPrint): Define.
2869 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2870 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2871 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2872 (w32_last_error): Remove.
2874 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2876 * w32heap.c (syspage_mask): Declare here.
2877 (cache_system_info): Remove.
2879 * w32inevt.c (faked_key): Define globally, not statically.
2880 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2881 (w32_console_toggle_lock_key): Move to w32fns.c.
2883 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2885 * w32proc.c (_DebPrint): Move to w32fns.c.
2886 * w32select.c: Include string.h, stdio.h for Cygwin.
2887 * w32select.h: New File.
2889 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2891 (w32_message_fd): New variable. Under Cygwin, holds the file
2892 descriptor the system used to tell us about pending thread
2895 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2896 that prevented compilation under non-WINDOWSNT systems.
2898 (w32_initialize): Open /dev/windows and assign it to
2899 w32_message_fd. Provide w32 feature.
2901 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2902 (WM_EMACS_INPUT_READY): add.
2903 (prepend_msg, w32_message_fd): Declare globally.
2906 (keyboard_handle): Use only when WINDOWSNT.
2907 (notify_msg_ready): New function. Posts a message to the main
2908 thread's message queue under CYGWIN, which wakes up the main
2909 thread from select(2) by making the /dev/windows file descriptor
2910 ready. Under WINDOWSNT, it sets an event the same way the old
2913 (post, prepend_msg): Actually call notify_msg_ready instead of
2914 setting the input event directly.
2916 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2918 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2919 but it still has blocs in it, don't return it to the system,
2920 instead of aborting. (Bug#12402)
2922 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2924 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2926 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2927 MAC_OS_X_VERSION_10_6.
2928 (syms_of_nsterm): Remove comment about Panther and above for
2930 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2931 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2932 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2934 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2935 MAC_OS_X_VERSION_10_4.
2937 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2938 MAC_OS_X_VERSION_10_2.
2940 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2942 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2943 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2945 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2946 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2947 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2948 Remove ns_in_resize check.
2949 (ns_clear_frame_area): Remove resize handle code.
2951 * nsfns.m (ns_in_resize): Remove.
2952 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2953 Remove ns_in_resize check.
2955 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2957 Improve sys_siglist detection.
2958 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2959 defined as a macro, as is done in Solaris.
2960 (sys_siglist_entries): New macro.
2961 (save_strsignal): Use it.
2962 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2963 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2965 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2967 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2968 fullscreen/Fullscreen.
2970 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2971 tobar_height is new.
2973 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2974 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2975 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2976 (windowDidResize:): Check for correct window if old style fullscreen.
2977 Capitalize word in comment. Remove incorrect comment.
2978 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2979 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2980 error in drawing background.
2981 (toggleFullScreen:): Remove comment. Rearrange calls.
2982 Set toolbar values to zero, save old height in tobar_height.
2983 Restore tool bar height when leaving fullscreen.
2984 (canBecomeMainWindow): New function.
2986 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2988 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2990 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2992 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2994 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2995 that time stamps of directories could also be changed.
2996 Don't request the too broad GENERIC_WRITE, only the more restrictive
2997 FILE_WRITE_ATTRIBUTES access rights.
2999 * fileio.c (Fset_file_times): Special-case ignoring errors for
3000 directories only on MSDOS, not on MS-Windows.
3002 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3004 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3006 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3008 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3009 see whether CreateFile failed.
3011 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3013 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3014 to avoid similar races.
3015 * keyboard.c (pending_signals): Now bool, not int.
3017 Port timers to OpenBSD, plus check for timer failures.
3018 OpenBSD problem reported by Han Boetes.
3019 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3021 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3022 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3023 like OpenBSD, which has timer_settime but does not declare it.
3024 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3025 whether to use itimerspec-related primitives. All uses of
3026 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3028 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3030 * profiler.c (handle_profiler_signal): Fix a malloc race
3031 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3033 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3035 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3037 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3039 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3040 consistent with the change in return value of 'safe_strsignal'.
3042 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3044 Prefer plain 'static' to 'static inline' (Bug#12541).
3045 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3046 (bidi_set_sor_type, bidi_push_embedding_level)
3047 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3048 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

3051 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3052 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3053 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3054 Now 'static', not 'static inline'.
3056 Count overruns when profiling; change units to ns.
3057 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3058 Give extra weight to samples after overruns, to attempt to count
3059 the time more accurately.
3060 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3061 the underlying primitives nominally do ns.
3062 (Fprofiler_cpu_start): Document the change. Mention that
3063 the sampling intervals are only approximate.
3065 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3067 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3069 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3070 case for the special 0 coding-system.
3072 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3073 (Fmake_overlay): Remove redundant tests.
3074 (fix_start_end_in_overlays): Remove redundant recentering.
3076 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3078 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3079 Update dependencies.
3081 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3083 Fix a malloc race condition involving strsignal.
3084 A signal can arrive in the middle of a malloc, and Emacs's signal
3085 handler can invoke strsignal, which can invoke malloc, which is
3086 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3087 Fix it by altering the signal handler so that it does not invoke
3089 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3090 * process.c (status_message): Use const pointer, in case strsignal
3091 is #defined to safe_strsignal.
3092 * sysdep.c (sys_siglist, init_signals): Always define and
3093 initialize a substitute sys_siglist if the system does not define
3094 one, even if HAVE_STRSIGNAL.
3095 (safe_strsignal): Rename from strsignal. Always define,
3096 using sys_siglist. Return a const pointer.
3097 * syssignal.h (safe_strsignal): New decl.
3098 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3100 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3102 * w32proc.c (timer_loop): Fix code that waits for timer
3103 expiration, to avoid high CPU usage.
3105 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3107 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3108 (sweep_weak_table): Remove redundant prototypes.
3110 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3112 * emacs.c: Move the inclusion of TERM_HEADER after including
3113 windows.h on WINDOWSNT. This avoids compilation problems with
3116 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3118 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3119 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3120 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3121 as the previous version used 'void *'.
3123 * ralloc.c (ROUNDUP): Fix last change.
3124 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3127 * w32proc.c <disable_itimers>: New static flag.
3128 (init_timers): Initialize it to zero, after creating the critical
3129 sections used by the timer threads.
3130 (term_timers): Set to 1 before deleting the critical sections.
3131 (getitimer, setitimer): If disable_itimers is non-zero, return an
3132 error indication without doing anything. Reported by Fabrice
3133 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3134 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3136 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3139 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3140 term_ntproc after all the other bookkeeping, to get timers working
3141 as long as possible.
3143 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3145 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3146 Suggested by Juri Linkov in
3147 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3149 Prefer plain 'static' to 'static inline' (Bug#12541).
3150 With static functions, modern compilers inline pretty well by
3151 themselves; advice from programmers often hurts as much as it helps.
3152 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3153 this change shrinks the text size of the Emacs executable by 1.1%
3154 without affecting CPU significantly in my benchmark.
3155 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
3156 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

3230 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
3231 Now 'static', not 'static inline'.
3234 (bidi_copy_it): Do the whole copy with a single memcpy.
3235 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3237 Revert the FOLLOW-SYMLINKS change for file-attributes.
3238 Doing it right would require several changes to Tramp, and there's
3239 not enough time to get that tested before the freeze today.
3240 * dired.c (directory_files_internal, Ffile_attributes):
3243 * frame.c (x_report_frame_params): Port better to wider ints.
3244 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3245 or that pointers can be printed in 15 decimal digits.
3246 Avoid GCC warnings if EMACS_UINT is wider than a pointer.
3248 2012-09-30 Fabrice Popineau <fabrice.popineau@supelec.fr>
3250 Support x64 build on MS-Windows.
3251 * w32term.h (SCROLL_BAR_PACK, SCROLL_BAR_UNPACK): Define for x64.

3253 compatibility with x64.
3254 (x_get_focus_frame): Add prototype.
3256 * w32term.c (w32_draw_underwave): Don't use GCC extensions for
3257 defining an XRectangle structure.
3259 * w32proc.c (RVA_TO_PTR, w32_executable_type): Fix pointer

3438 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
3439 signal.h, setjmp.h. Include systime.h instead.

3448 (handle_profiler_signal): Rename from sigprof_handler_1,
3449 for consistency with other handlers. Do not check whether
3450 cpu_log is a hash-table if garbage collecting, since it

3453 for consistency with other handlers.
3454 (setup_cpu_timer): New function, with much of what used to be in

3456 Prefer timer_settime if available, and prefer
3457 thread cputime clocks, then process cputime clocks, then
3458 monotonic clocks, to the old realtime clock. Use make_timeval
3459 to round more-correctly when falling back to setitimer.
3460 (Fprofiler_cpu_start): Use it.
3461 (Fprofiler_cpu_stop): Prefer timer_settime if available.

3603 (sys_kill): Improve commentary.
3605 * w32.c (term_ntproc): Accept (and ignore) one argument, for

3731 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3733 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3734 fatal_error_backtrace.
3736 * w32proc.c (sys_kill): Undo last change: don't do anything when
3737 invoked to deliver SIGABRT to our own process. This is now
3738 handled by emacs_raise.
3740 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3742 * w32term.c (w32_read_socket): Remove leftover reference to
3743 interrupt_input_pending.
3745 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3747 Do not use SA_NODEFER.
3748 Problem reported by Dani Moncayo in
3749 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3751 * sysdep.c (emacs_abort): Do not reset signal handler.
3752 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3753 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3754 wanted even on POSIXish hosts, and it doesn't work on Windows.
3756 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3758 * xterm.c (x_term_init): Call fixup_locale before and after calling
3759 gtk_init (Bug#12392).
3761 2012-09-23 Chong Yidong <cyd@gnu.org>
3763 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3764 Vdynamic_library_alist.
3766 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3767 (Fgnutls_available_p): Caller changed.
3769 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3770 (Flibxml_parse_xml_region): Likewise.
3772 * dispextern.h (struct image_type): Remove arg from init function.
3774 * image.c (Finit_image_library, lookup_image_type)
3775 (define_image_type): Remove now-unneeded second arg.
3776 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3777 (init_tiff_functions, init_gif_functions, init_svg_functions):
3778 Arglist and w32_delayed_load calling convention changed.
3779 (gs_type): Remove init_gs_functions; there is no such function.
3780 (valid_image_p, make_image): Fix caller to lookup_image_type.
3782 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3784 Simplify and avoid signal-handling races (Bug#12471).
3786 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3787 Avoid recursive loop if there's a fatal error in the function itself.
3788 * atimer.c (pending_atimers):
3789 * blockinput.h: Don't include "atimer.h"; no longer needed.
3790 (interrupt_input_pending): Remove. All uses removed.
3791 pending_signals now counts both atimers and ordinary interrupts.
3792 This is less racy than having three separate pending-signal flags.
3793 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3795 Rename from their upper-case counterparts BLOCK_INPUT,
3796 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3797 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3798 This makes it easier to access volatile variables more accurately.
3799 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3800 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3801 that's more reliable if the code is buggy and sets
3802 interrupt_input_blocked to a negative value. All uses changed.
3803 * atimer.c (deliver_alarm_signal):
3804 Remove. No need to deliver this to the parent; any thread can
3805 handle this signal now. All uses replaced by underlying handler.
3806 * atimer.c (turn_on_atimers):
3807 * dispnew.c (handle_window_change_signal):
3808 * emacs.c (handle_danger_signal):
3809 * keyboard.c (kbd_buffer_get_event):
3810 Don't reestablish signal handler; not needed with sigaction.
3811 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3813 Rework to avoid unnecessary accesses to volatile variables.
3814 (UNBLOCK_INPUT_TO): Now a function.
3815 (totally_unblock_input, unblock_input): New decls.
3816 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3817 (init_data): Remove. Necessary stuff now done in init_signal.
3818 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3819 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3820 (fatal_error_code): Remove; no longer needed.
3821 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3822 it doesn't always backtrace. All uses changed. No need to reset
3823 signal to default, since sigaction and/or die does that for us now.
3824 Use emacs_raise (FOO), not kill (getpid (), FOO).
3825 (main): Check more-accurately whether we're dumping.
3826 Move fatal-error setup to sysdep.c
3827 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3828 * gtkutil.c (xg_get_file_name, xg_get_font):
3829 Remove no-longer-needed signal-mask manipulation.
3830 * keyboard.c, process.c (POLL_FOR_INPUT):
3831 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3832 * keyboard.c (read_avail_input): Remove.
3833 All uses replaced by gobble_input.
3834 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3835 (kbd_buffer_store_event_hold, gobble_input):
3836 (record_asynch_buffer_change) [USABLE_SIGIO]:
3837 (store_user_signal_events):
3838 No need to mess with signal mask.
3839 (gobble_input): If blocking input and there are terminals, simply
3840 set pending_signals to 1 and return. All hooks changed to not
3841 worry about whether input is blocked.
3842 (process_pending_signals): Clear pending_signals before processing
3843 them, in case a signal comes in while we're processing.
3844 By convention callers now test pending_signals before calling us.
3845 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3846 New functions, to support changes to blockinput.h.
3847 (handle_input_available_signal): Now extern.
3848 (reinvoke_input_signal): Remove. All uses replaced by
3850 (quit_count): Now volatile, since a signal handler uses it.
3851 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3852 All callers changed. Block SIGINT only if not already blocked.
3853 Clear sigmask reliably, even if Fsignal returns, which it can.
3854 Omit unnecessary accesses to volatile var.
3855 (quit_throw_to_read_char): No need to restore sigmask.
3856 * keyboard.c (gobble_input, handle_user_signal):
3857 * process.c (wait_reading_process_output):
3858 Call signal-handling code rather than killing ourselves.
3859 * lisp.h: Include <float.h>, for...
3860 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3861 (pending_signals): Now volatile.
3862 (syms_of_data): Now const if IEEE floating point.
3863 (handle_input_available_signal) [USABLE_SIGIO]:
3864 (terminate_due_to_signal, record_child_status_change): New decls.
3865 * process.c (create_process): Avoid disaster if memory is exhausted
3866 while we're processing a vfork, by tightening the critical section
3868 (send_process_frame, process_sent_to, handle_pipe_signal)
3869 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3871 (send_process): No need for setjmp/longjmp any more, since the
3872 SIGPIPE stuff is now gone. Instead, report an error if errno
3874 (record_child_status_change): Now extern. PID and W are now args.
3875 Return void, not bool. All callers changed.
3876 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3877 Remove. All uses removed. This bug should be fixed now in a
3879 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3880 and record the child status change directly. This avoids the
3881 need to futz with the signal mask.
3882 (process_fatal_action): Move here from emacs.c.
3883 (emacs_sigaction_flags): New function, containing
3884 much of what used to be in emacs_sigaction_init.
3885 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3886 caught by emacs, to make races less likely.
3887 (deliver_process_signal): Rename from handle_on_main_thread.
3889 (BACKTRACE_LIMIT_MAX): Now at top level.
3890 (thread_backtrace_buffer, threadback_backtrace_pointers):
3892 (deliver_thread_signal, deliver_fatal_thread_signal):
3893 New functions, for more-accurate delivery of thread-specific signals.
3894 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3895 (deliver_arith_signal): Handle in this thread, not
3896 in the main thread, since it's triggered by this thread.
3897 (maybe_fatal_sig): New function.
3898 (init_signals): New arg DUMPING so that we can be more accurate
3899 about whether we're dumping. Caller changed.
3900 Treat thread-specific signals differently from process-general signals.
3901 Block all signals while handling fatal error; that's safer.
3902 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3904 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3905 Ignore SIGPIPE unless batch.
3906 (emacs_backtrace): Output backtrace for the appropriate thread,
3907 which is not necessarily the main thread.
3908 * syssignal.h: Include <stdbool.h>.
3909 (emacs_raise): New macro.
3910 * xterm.c (x_connection_signal): Remove; no longer needed
3911 now that we use sigaction.
3912 (x_connection_closed): No need to mess with sigmask now.
3913 (x_initialize): No need to reset SIGPIPE handler here, since
3914 init_signals does this for us now.
3916 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3918 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3919 background rect may be larger (Bug#12245).
3921 2012-09-23 Chong Yidong <cyd@gnu.org>
3923 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3925 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3927 * .gdbinit: Just stop at fatal_error_backtrace.
3928 See Stefan Monnier's request in
3929 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3930 Remove no-longer-used query of system type.
3932 2012-09-22 Chong Yidong <cyd@gnu.org>
3934 * search.c (Freplace_match): Doc fix (Bug#12325).
3936 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3938 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3939 (Fline_end_position): Doc fix.
3941 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3943 2012-09-22 Chong Yidong <cyd@gnu.org>
3945 * dispextern.h (struct image_type): Add new slot, storing a type
3946 initialization function.
3948 * image.c (define_image_type): Call the image initializer function
3949 if it is defined. Arguments and return value changed.
3950 (valid_image_p, make_image): Callers changed.
3951 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3952 (gif_type, imagemagick_type, svg_type, gs_type):
3953 Add initialization functions.
3954 (Finit_image_library): Call lookup_image_type.
3955 (CHECK_LIB_AVAILABLE): Macro deleted.
3956 (lookup_image_type): Call define_image_type here, rather than via
3957 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3958 (syms_of_image): Move define_image_type calls for xbm_type and
3959 pbm_type to lookup_image_type.
3961 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3963 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3964 'idle_timers' from here ...
3965 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3966 lists, to avoid infloops when the timer does something stupid,
3967 like reinvoke itself with the same or smaller time-out.
3970 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3972 * window.c (Fsplit_window_internal): Handle only Qt value of
3973 Vwindow_combination_limit separately.
3974 (Qtemp_buffer_resize): New symbol.
3975 (Vwindow_combination_limit): New default value.
3978 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3980 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3981 the new overlay string. (Bug#10159)
3983 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3985 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3986 or that fprintf is async-signal-safe. POSIX doesn't require
3989 2012-09-22 Chong Yidong <cyd@gnu.org>
3991 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3994 2012-09-22 Kenichi Handa <handa@gnu.org>
3996 * composite.c (composition_reseat_it): Handle the case that a
3997 grapheme cluster is not covered by a single font (Bug#12352).
3999 2012-09-21 Chong Yidong <cyd@gnu.org>
4001 * image.c (define_image_type): Avoid adding duplicate types to
4002 image_types (Bug#12463). Suggested by Jörg Walter.
4004 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4006 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4007 (print_load_command_name): Add case LC_DATA_IN_CODE.
4008 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4010 2012-09-21 Glenn Morris <rgm@gnu.org>
4012 * eval.c (Frun_hook_with_args_until_success)
4013 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4015 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4017 * fileio.c (Ffile_selinux_context): Only call freecon when
4018 lgetfilecon succeeded.
4019 (Fset_file_selinux_context): Likewise. (Bug#12444)
4021 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4023 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4024 reordering, locate the cursor by calling set_cursor_from_row; if
4025 that fails, clear the desired glyph matrix before returning a
4026 failure indication to the caller. Fixes leaving garbled display
4027 when fast scrolling with a down-key. (Bug#12403)
4028 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4029 scrolling through multibyte text.
4031 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4033 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4034 calling mark_vectorlike since that's the one that marks the window.
4035 (mark_discard_killed_buffers): Mark the final cdr.
4036 * window.h (struct window): Move prev/next_buffers to the
4037 non-standard fields.
4038 * window.c (make_window): Initialize prev/next_buffers manually.
4040 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4042 Omit unused arg EXPECTED from socket hooks.
4043 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4044 * nsterm.m (ns_term_init):
4045 * termhooks.h (struct terminal.read_socket_hook):
4046 * w32inevt.c (w32_console_read_socket):
4047 * w32term.c (w32_read_socket):
4048 * xterm.c (XTread_socket):
4049 Omit unused arg EXPECTED. All callers changed.
4050 (store_user_signal_events): Return void, not int, since callers no
4051 longer care about the return value. All uses changed.
4053 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4055 * w32gui.h (XParseGeometry): Do not declare.
4057 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4059 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4060 Ignore 'expected'. See Eli Zaretskii in
4061 <http://bugs.gnu.org/12471#8> (last line).
4063 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4064 (XParseGeometry): Now static. Substitute extremal values for
4065 values that are out of range.
4067 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4069 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4071 * nsfns.m (XParseGeometry): Remove.
4072 (Fx_create_frame): Call x_set_offset to correctly interpret
4073 top_pos in geometry.
4075 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4076 (Fx_parse_geometry): If there is a space in string, call
4077 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4079 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4081 * search.c (scan_buffer): Use character positions in calls to
4082 region_cache_forward and region_cache_backward, not byte
4083 positions. (Bug#12196)
4085 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4086 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4088 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4089 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4090 emacs_blocked_malloc, now deleted.
4092 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4094 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4095 The workaround was for improving performance on Solaris 2.4, but
4096 is getting in the way now. Emacs will still work if someone is
4097 still running Solaris 2.4 in a museum somewhere; Sun dropped
4098 support for Solaris 2.4 in 2003.
4099 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4100 * process.c (create_process) [HAVE_WORKING_VFORK]:
4101 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4102 since Emacs no longer uses vfork on that platform.
4104 2012-09-17 Glenn Morris <rgm@gnu.org>
4106 * emacs.c: Use COPYRIGHT.
4108 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4110 Remove configure's --without-sync-input option (Bug#12450).
4111 When auditing signal-handling in preparation for cleaning it up,
4112 I found that SYNC_INPUT has race conditions and would be a real
4113 pain to fix. Since it's an undocumented and deprecated
4114 configure-time option, now seems like a good time to remove it.
4115 Also see <http://bugs.gnu.org/11080#16>.
4116 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4117 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4118 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4119 (malloc_hysteresis):
4120 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4121 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4122 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4123 (dont_register_blocks, bytes_used_when_reconsidered)
4124 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4125 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4126 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4127 Remove. All uses removed.
4128 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4129 implementation, one that depends on whether the new macro
4130 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4132 * atimer.c (run_timers, handle_alarm_signal):
4133 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4134 (handle_async_input, process_pending_signals)
4135 (handle_input_available_signal, init_keyboard):
4136 * nsterm.m (ns_read_socket):

4141 * xterm.c (XTread_socket):
4143 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4144 * eval.c (handling_signal): Remove. All uses removed.
4145 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4146 All uses replaced with the SYNC_INPUT version.
4147 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4149 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4152 * font.c (Ffont_shape_gstring): Remove unused local.
4154 2012-09-16 Glenn Morris <rgm@gnu.org>
4156 * Makefile.in (clean): No longer run nextstep's clean.
4158 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4160 (ns-app): Move here from ns.mk, and simplify.
4161 (clean): Simplify nextstep entry.
4162 * ns.mk: Remove file.
4164 2012-09-17 Kenichi Handa <handa@gnu.org>
4166 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4167 not covert the last few charactes.
4169 2012-09-16 Kenichi Handa <handa@gnu.org>
4171 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4172 here, but just check the validity of glyphs in the glyph-string.
4174 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4176 * window.c (Fwindow_parameter, Fset_window_parameter):
4177 Accept any window as argument (Bug#12452).
4179 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4181 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4182 to ns_term_init to avoid memory leak.
4184 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4185 explicit retain/release.
4186 (ns_term_init): Only allow one display. Initialize outerpool and
4189 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4191 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4192 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4193 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4194 the Microsoft problem in a different way, by altering ../nt/config.nt.
4196 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4211 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4212 by lisp.h. This completes removal of setjmp.h inclusion
4213 erroneously announced in the previous commit. (Bug#12446)
4215 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4218 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4219 not defined as a macro. The latter happens on MS-Windows.
4222 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4224 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4225 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4226 Some instances of '#include <setjmp.h>' removed, if the
4227 only reason for the instance was because "lisp.h" was included.
4228 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4229 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4230 and _longjmp with the new symbols. Emacs already uses _setjmp if
4231 available, so this change affects only POSIXish hosts that have
4232 sigsetjmp but not _setjmp, such as some versions of Solaris and
4233 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4234 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4235 (png_load_body) [HAVE_PNG]:
4236 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4237 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4238 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4239 since PNG requires jmp_buf. This is the only exception to the
4240 general rule that we now use sys_setjmp and sys_longjmp.
4241 This exception is OK since this code does not change the signal
4242 mask or longjmp out of a signal handler.
4244 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4246 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4247 Include "syssignal.h", for 'main_thread'.
4249 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4251 Avoid out-of-range marker position (Bug#12426).
4252 * insdel.c (replace_range, replace_range_2):
4253 Adjust markers before overlays, as suggested by comments.
4254 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4255 Remove redundant check before calling offset_intervals.
4257 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4259 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4260 current buffer (Bug#12387).
4262 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4264 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4266 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4268 Use a more backwards-compatible timer format (Bug#12430).
4269 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4270 vector element, not from the 4th, since PSECS is now at the end.
4271 (Fcurrent_idle_time): Doc fix.
4273 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4275 Function to mark objects and remove killed buffers at once.
4276 * alloc.c (discard_killed_buffers): Rename to ...
4277 (mark_discard_killed buffers) ... new name. Add marking
4278 of remaining objects. Fix comment. Adjust users.
4279 (mark_object): Do not touch frame buffer lists here.
4280 * frame.c (delete_frame): Reset frame buffer lists here.
4282 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4284 Better workaround for GNOME bug when --enable-gcc-warnings.
4285 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4286 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4287 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4289 Simplify SIGIO usage (Bug#12408).
4290 The code that dealt with SIGIO was crufty and confusing, e.g., it
4291 played tricks like "#undef SIGIO" but these tricks were not used
4292 consistently. Simplify mostly by not #undeffing standard symbols,
4293 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4294 or not as we please) rather than "defined SIGIO" (standard symbol
4295 that we probably shouldn't #undef).
4296 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4297 Modules that need it can include it.
4298 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4299 * dispextern.h (ignore_sigio): New decl.
4300 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4301 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4302 * emacs.c (shut_down_emacs):
4303 * keyboard.c (kbd_buffer_store_event_hold):
4304 Use ignore_sigio rather than invoking 'signal' directly.
4305 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4307 (FIONREAD, SIGIO): Do not #undef.
4308 (tty_read_avail_input): Use #error rather than a syntax error.
4309 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4310 for I_PIPE, used by SETUP_SLAVE_PTY.
4311 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4312 * sysdep.c (croak): Remove; no longer needed. This bit of
4313 temporary code, with Fred N. Fish's comment that it's temporary,
4314 has been in Emacs since at least 1992!
4315 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4316 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4317 * syssignal.h (croak): Remove decl.
4318 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4319 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4320 now that we're termios-only.
4321 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4322 * term.c (dissociate_if_controlling_tty): Use #error rather than
4325 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4326 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4327 to work around GNOME bug 683906.
4328 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4329 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4330 This works around GCC bug 54561.
4332 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4334 More fixes for 'volatile' and setjmp/longjmp.
4335 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4336 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4337 (png_load_body) [HAVE_PNG]:
4338 (jpeg_load_body) [HAVE_JPEG]:
4339 New function, with most of the old parent function's body.
4340 (png_load) [HAVE_PNG]:
4341 (jpeg_load) [HAVE_JPEG]:
4342 Invoke the new function, to avoid longjmp munging our locals.
4343 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4344 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4345 longjmp is passed 2, as the C standard doesn't guarantee this.
4346 Instead, store the failure code into mgr->failure_code.
4348 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4350 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4351 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4352 (syms_of_keyboard): Remove support for unread-command-char.
4354 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4356 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4357 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4358 violation. (Bug#12426)
4360 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4362 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4364 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4366 * eval.c: Add `inhibit-debugger'.
4367 (Qinhibit_debugger): New symbol.
4368 (call_debugger): Bind it instead of Qdebug_on_error.
4369 (maybe_call_debugger): Test Vinhibit_debugger.
4370 (syms_of_eval): Define inhibit-debugger.
4371 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4372 (syms_of_xdisp): Remove inhibit-debug-on-message.
4374 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4376 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4377 If a nonvolatile local variable is written before a _longjmp to
4378 the frame containing the variable, and is read after the _longjmp,
4379 the value read is indeterminate. Some local variables of type
4380 'struct handler' and 'struct catchtag' are used in this way, so
4381 mark each of their slots as volatile if the slot can be set before
4382 _longjmp and read afterwards.
4383 * lisp.h (struct handler): var and chosen_clause are now volatile.
4384 (struct catchtag): val, next, and pdlcount are now volatile.
4386 * bidi.c (bidi_push_it, bidi_pop_it):
4387 * fns.c (copy_hash_table):
4388 * image.c (define_image_type):
4389 * keyboard.c (kbd_buffer_store_event_hold):
4390 * process.c (Fprocess_send_eof):
4391 * xfaces.c (x_create_gc) [HAVE_NS]:
4392 * xgselect.c (xg_select):
4393 Prefer assignment to memcpy when either will do.
4395 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4396 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4397 time an item is removed. No need to mark this function 'inline';
4398 the compiler knows better than we do.
4400 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4402 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4403 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4404 to change_frame_size (Bug#12388).
4405 (windowDidResize:): Pass YES to updateFrameSize.
4407 * nsterm.h: Add delay parameter to updateFrameSize.
4409 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4411 Discard killed buffers from deleted window and frame objects.
4412 This reduces an amount of references to killed buffers and
4413 helps GC to reclaim them faster.
4414 * alloc.c (discard_killed_buffers): New function.
4415 (mark_object): Use it for deleted windows and frames.
4416 (mark_object): If symbol's value is set up for a killed buffer
4417 or deleted frame, restore its global binding.
4418 * data.c (swap_in_global_binding): Add GC notice.
4419 (swap_in_symval_forwarding): Use convenient set_blv_where.
4420 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4421 * window.h: ... to here.
4423 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4425 Convenient macro to check whether the buffer is live.
4426 * buffer.h (BUFFER_LIVE_P): New macro.
4427 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4428 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4430 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4432 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4433 composition cases (Bug#12364).
4435 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4436 overhang of succeeding glyphs overlapping box cursor.
4438 * w32term.c (x_draw_glyph_string): Likewise.
4440 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4442 Simplify, document, and port floating-point (Bug#12381).
4443 The porting part of this patch fixes bugs on non-IEEE platforms
4444 with frexp, ldexp, logb.
4445 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4447 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4448 support, by removing commented-out code and briefly listing the
4449 C89 functions excluded. The commented-out stuff was confusing
4450 maintenance, e.g., we thought we needed cbrt but it was commented out.
4451 (logb): Remove decl; no longer needed.
4452 (isfinite): New macro, if not already supplied.
4453 (isnan): Don't replace any existing macro.
4454 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4455 are present on all C89 platforms.
4456 (Ffrexp): Do not special-case zero, as frexp does the right thing
4458 (Flogb): Do not use logb, as it doesn't have the desired meaning
4459 on hosts that use non-base-2 floating point. Instead, stick with
4460 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4461 frexp, to avoid getting an unspecified result.
4463 * xdisp.c (Qinhibit_debug_on_message): Now static.
4465 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4467 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4468 NSBezierPath (Bug#12131).
4470 2012-09-10 Chong Yidong <cyd@gnu.org>
4472 * fns.c (Fdelq, Fdelete): Doc fix.
4474 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4476 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4477 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4479 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4481 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4482 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4485 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4487 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4488 left fringe if the window has a left margin. This avoids leaving
4489 traces of the cursor because its leftmost pixel is not drawn over.
4491 * dispnew.c (update_window_line): When the left margin area of a
4492 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4493 that screen line. (Bug#12277)
4495 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4497 Assume C89 or later for math functions (Bug#12381).
4498 This simplifies the code, and makes it a bit smaller and faster,
4499 and (most important) makes it easier to clean up signal handling
4500 since we can stop worring about floating-point exceptions in
4501 library code. That was a problem before C89, but the problem
4502 went away many years ago on all practical Emacs targets.
4503 * data.c, image.c, lread.c, print.c:
4504 Don't include <math.h>; no longer needed.
4505 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4506 might be autoconfigured, as that never happens.
4508 * doprnt.c (DBL_MAX_10_EXP):
4509 * print.c (DBL_DIG):
4510 Remove. C89 or later always defines these.
4511 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4512 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4513 (arith_error, domain_error, domain_error2):
4514 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4515 no longer needed -- we simply return what C returns. All uses removed.
4516 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4518 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4519 Remove. All uses expanded, as these macros are no longer used
4520 more than once and are now more trouble than they're worth.
4521 (Ftan): Use tan, not sin / cos.
4522 (Flogb): Assume C89 frexp.
4523 (fmod_float): Assume C89 fmod.
4524 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4525 (init_floatfns): Remove. All uses removed.
4527 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4529 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4530 compositeToPoint for OSX < 10.6 (Bug#12390).
4532 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4534 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4535 This produces more-accurate results.
4537 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4539 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4540 changes (Bug#12088).
4542 2012-09-08 Chong Yidong <cyd@gnu.org>
4544 * syntax.c (Fstring_to_syntax): Doc fix.
4546 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4548 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4549 in the internal border.
4550 (x_set_window_size): Remove static variables and their usage.
4551 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4552 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4553 Remove fringe/internal border adjustment (Bug#11052).
4554 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4555 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4556 (ns_fix_rect_ibw): Remove.
4557 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4558 (ns_dumpglyphs_box_or_relief): Ditto.
4559 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4561 (ns_dumpglyphs_image): Ditto.
4562 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4564 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4565 their usage. Add fringe_extended_p and its use as in other terms.
4566 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4567 scroll bar was removed.
4568 (updateFrameSize): New function.
4569 (windowDidResize): Move code to updateFrameSize and call it.
4571 * nsterm.h (EmacsView): Add updateFrameSize.
4573 2012-09-07 Chong Yidong <cyd@gnu.org>
4575 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4577 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4579 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4581 More signal-handler cleanup (Bug#12327).
4582 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4583 Problem introduced when merging patches. Noted by Eli Zaretskii in
4584 <http://bugs.gnu.org/12327#67>.
4585 * floatfns.c: Comment fix.
4586 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4587 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4588 and anyway the declaration is harmless even if SIGDANGER is not defined.
4589 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4590 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4591 source files not surprisingly expected syssignal.h to define, or
4592 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4593 Include <sys/ioctl.h>, for FIONREAD.
4594 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4595 This eliminates a problem whereby other files mysteriously had
4596 to include "syssignal.h" before including "systty.h" if they
4597 wanted to use "#ifdef SIGIO".
4599 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4601 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4603 * w32.c (sigemptyset): Empty the set.
4604 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4606 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4608 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4610 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4611 (mark_object): Likewise for frame objects.
4613 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4615 * syssignal.h (handle_on_main_thread): Always declare,
4616 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4617 This ports to platforms without HAVE_PTHREAD.
4619 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4621 Signal-handler cleanup (Bug#12327).
4622 Emacs's signal handlers were written in the old 4.2BSD style with
4623 sigblock and sigmask and so forth, and this led to some
4624 inefficiencies and confusion. Rewrite these to use
4625 pthread_sigmask etc. without copying signal sets around. Also,
4626 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4627 'signal', and instead use functions that do not attempt to take
4628 over the system name space. This patch causes Emacs's text
4629 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4630 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4631 Do not include <signal.h> or "syssignal.h", as these
4632 modules do not use signals.
4633 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4634 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4635 Do not include <signal.h>, as "syssignal.h" does that for us now.
4636 * atimer.c (sigmask_atimers): New function.
4637 (block_atimers, unblock_atimers): New functions,
4638 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4640 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4641 no longer needed here.
4642 * emacs.c (main): Inspect existing signal handler with sigaction,
4643 so that there's no need to block and unblock SIGHUP.
4644 * sysdep.c (struct save_signal): New member 'action', replacing
4645 old member 'handler'.
4646 (save_signal_handlers, restore_signal_handlers):
4647 Use sigaction instead of 'signal' to save and restore.
4648 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4649 New function. All users of 'signal' modified to use set_sighandler
4650 if they're writeonly, and to use sys_signal if they're read+write.
4651 (emacs_sigaction_init, forwarded_signal): New functions.
4652 (sys_signal): Remove. All uses replaced by calls to sigaction
4653 and emacs_sigaction_init, or by direct calls to 'signal'.
4654 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4655 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4656 all uses replaced by pthread_sigmask etc. calls.
4657 * syssignal.h: Include <signal.h>.
4658 (emacs_sigaction_init, forwarded_signal): New decls.
4659 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4660 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4661 (sigmask, sys_sigmask): Remove; no longer needed.
4662 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4663 (sigblock, sigunblock, sigfree):
4664 (sigsetmask) [!defined sigsetmask]:
4665 Remove. All uses replaced by pthread_sigmask.
4666 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4667 no longer need to be replaced, and its typical old uses
4668 are now done via emacs_sigaction_init and sigaction.
4669 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4670 (sys_sigdel): Remove; unused.
4671 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4673 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4675 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4676 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4678 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4680 Explicitly mark buffer_defaults and buffer_local_symbols.
4681 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4682 mark_local_symbols here.
4683 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4684 since special buffers aren't marked here any more.
4685 (allocate_buffer): Chain new buffer with all_buffers here...
4686 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4688 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4689 (syms_of_buffer): Remove staticpro of the above.
4690 (init_buffer_once): Set names for buffer_defaults and
4691 buffer_local_symbols.
4693 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4695 Use bool for booleans in font-related modules.
4696 * font.c (font_intern_prop, font_style_to_value)
4697 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4698 (generate_otf_features, font_check_otf_features, font_check_otf)
4699 (font_match_p, font_list_entities, font_at):
4700 * fontset.c (fontset_id_valid_p, reorder_font_vector
4701 (fontset_find_font, Fset_fontset_font)
4702 (face_suitable_for_char_p) [0]:
4703 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4704 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4705 (m17n_flt_initialized, ftfont_shape_by_flt):
4706 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4707 * nsfont.m (nsfont_draw):
4708 * w32font.c (w32font_draw):
4709 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4710 Use bool for booleans.
4711 * font.h: Adjust to above API changes.
4712 (struct font, struct font_driver, struct font_driver_list):
4713 Use bool for booleans.
4714 (struct font): Remove useless member encoding_type.
4716 * fontset.c, xftfont.c: Omit unnecessary static decls.
4718 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4720 * alloc.c (mark_object): Revert window marking code
4721 since it's unsafe for the Fset_window_configuration.
4723 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4725 Fix race conditions with signal handlers and errno (Bug#12327).
4726 Be more systematic about preserving errno whenever a signal
4727 handler returns, even if it's not in the main thread. Do this by
4728 renaming signal handlers to distinguish between signal delivery
4729 and signal handling. All uses changed.
4730 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4731 * data.c (deliver_arith_signal): Rename from arith_error.
4732 * dispnew.c (deliver_window_change_signal): Rename from
4733 window_change_signal.
4734 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4735 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4736 * keyboard.c (deliver_input_available_signal): Rename from
4737 input_available_signal.
4738 (deliver_user_signal): Rename from handle_user_signal.
4739 (deliver_interrupt_signal): Rename from interrupt_signal.
4740 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4741 (deliver_child_signal): Rename from sigchld_handler.
4742 * atimer.c (handle_alarm_signal):
4743 * data.c (handle_arith_signal):
4744 * dispnew.c (handle_window_change_signal):
4745 * emacs.c (handle_fatal_signal, handle_danger_signal):
4746 * keyboard.c (handle_input_available_signal):
4747 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4748 * process.c (handle_pipe_signal, handle_child_signal):
4749 New functions, with the actual signal-handling code taken from the
4750 original respective signal handlers, sans the sporadic attempts to
4751 preserve errno, since that's now done by handle_on_main_thread.
4752 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4753 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4754 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4756 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4757 Move initialization of main_thread to sysdep.c's init_signals.
4758 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4759 our usage, and simplifies the mainline code.
4760 (record_child_status_change): New static function, as a helper
4761 for handle_child_signal, and with most of the old child handler's
4763 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4764 (handle_child_signal): Use the above.
4765 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4766 Moved here from emacs.c.
4767 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4768 code moved here from emacs.c's main function.
4769 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4770 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4771 This lets callers save and restore errno properly.
4773 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4775 Remove redundant or unused things here and there.
4776 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4777 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4778 * editfns.c (Fcompare_buffer_substrings): Likewise.
4779 * frame.h (struct terminal, struct font_driver_list):
4780 Remove redundant declarations.
4781 * window.h (Qleft, Qright): Likewise.
4783 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4785 Do not mark objects from deleted buffers, windows and frames.
4786 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4787 (mark_object): Likewise for windows and frames.
4789 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4791 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4792 buffer_defaults and buffer_local_symbols as valid objects.
4793 Return special value to denote them.
4795 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4797 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4798 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4799 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4800 (file_name_absolute_p, Fsubstitute_in_file_name):
4801 (check_executable, check_writable, Ffile_accessible_directory_p)
4802 (Fset_file_selinux_context, Fdefault_file_modes)
4803 (Finsert_file_contents, choose_write_coding_system)
4804 (Fwrite_region, build_annotations, a_write, e_write)
4806 * filelock.c (boot_time_initialized, get_boot_time)
4807 (get_boot_time_1, lock_file_1, within_one_second):
4808 * floatfns.c (in_float):
4809 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4810 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4811 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4812 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4813 * window.c (compare_window_configurations):
4814 Use bool for booleans.
4815 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4816 (Fdefault_file_modes): Now mode_t, not int, for modes.
4817 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4818 (internal_delete_file): Now returns void, not a (boolean) int,
4819 since nobody was looking at the return value.
4820 * lisp.h, window.h: Adjust to above API changes.
4822 * xdisp.c (set_message): Simplify and reindent last change.
4824 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4826 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4828 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4830 * eval.c (call_debugger): Make the function non-static so that we
4831 can call it from set_message.
4833 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4834 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4836 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4838 Give more-useful info on a fatal error (Bug#12328).
4839 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4840 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4841 of doing the work ourselves.
4842 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4843 do most of the work.
4844 (fatal_error_backtrace): New function, taken from the guts
4845 of the old fatal_error_signal, but with a new option to output
4847 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4848 info about the signal than just its number.
4849 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4850 * sysdep.c: Include <execinfo.h>
4851 (emacs_backtrace): New function, taken partly from the previous
4852 code of the 'die' function.
4853 (emacs_abort): Call fatal_error_backtrace rather than abort.
4855 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4857 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4858 eager (load-time) macro-expansion.
4859 * lisp.mk (lisp): Add macroexp.
4861 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4863 Simplify redefinition of 'abort' (Bug#12316).
4864 Do not try to redefine the 'abort' function. Instead, redo
4865 the code so that it calls 'emacs_abort' rather than 'abort'.
4866 This removes the need for the NO_ABORT configure-time macro
4867 and makes it easier to change the abort code to do a backtrace.
4868 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4869 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4870 Remove; sysdep.c's emacs_abort now takes its place.
4871 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4872 'abort' changed to use 'emacs_abort'.
4873 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4874 (abort) [!defined abort]: Rename to ...
4875 (emacs_abort): ... new name.
4876 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4877 the place of the old 'abort' in emacs.c.
4878 * w32.c, w32fns.c (abort): Do not #undef.
4879 * w32.c (emacs_abort): Rename from w32_abort.
4881 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4883 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4884 offsets[j].dv, since the y axis of the screen coordinates points
4885 down, while the y axis of the font definition coordinates points
4886 up. This fixes display of Arabic diacritics such as KASRA and
4887 KASRATAN. (Bug#11860)
4889 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4891 Be more systematic about _setjmp vs setjmp.
4892 * alloc.c (test_setjmp, mark_stack):
4893 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4894 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4895 (png_load, my_error_exit, jpeg_load):
4896 * process.c (send_process_trap, send_process):
4897 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4898 The underscored versions are up to 30x faster on some hosts.
4899 Formerly, the code used setjmp+longjmp sometimes and
4900 _setjmp+_longjmp at other times, with no particular reason to
4901 prefer setjmp+longjmp.
4903 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4905 Fix minor problem found by static checking.
4906 * buffer.c (Fdelete_all_overlays): Return nil.
4908 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4910 * buffer.c (Fdelete_all_overlays): New function.
4912 2012-09-03 Chong Yidong <cyd@gnu.org>
4914 * gtkutil.c: Add extern decl for Qxft.
4916 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4918 * emacs.c, eval.c: Use bool for boolean.
4919 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4920 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4921 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:

4926 (maybe_call_debugger, Fbacktrace):
4927 * process.c (read_process_output, exec_sentinel):
4928 Use bool for booleans.
4929 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4930 All callers changed.
4931 * eval.c (interactive_p): Omit always-true boolean argument
4932 EXCLUDE_SUBRS_P. All callers changed.
4933 * dispextern.h, lisp.h: Reflect above API changes.
4934 * firstfile.c (dummy): Use the address of 'main', whose signature
4935 won't change, instead of the address of 'initialize', whose
4936 signature just changed from int to bool.
4937 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4938 * msdos.c (fatal_error_in_progress): ... from here.
4939 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4941 (redisplay_internal, unwind_redisplay): Simply clear
4942 REDISPLAYING_P when unwinding, instead of saving its previous,
4943 always-false value and then restoring it.
4945 Clean up some extern decls.
4946 Mostly, this hoists extern decls out of .c files and into .h files.
4947 That way, we're more likely to catch errors if the interfaces change.
4948 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4949 declare xg_mark_data.
4950 * dispextern.h (x_frame_parm_handlers):
4952 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4953 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4954 (Qultra_bold, Qoblique, Qitalic):
4955 Move extern decl here from .c file.
4956 * alloc.c (xg_mark_data) [USE_GTK]:
4958 * eval.c (Qlexical_binding):
4959 * fns.c (time) [!HAVE_UNISTD_H]:

4968 * xfont.c (x_clear_errors):
4969 * xterm.c (x_frame_parm_handlers):
4970 Remove now-redundant extern decls.
4971 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4972 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4974 * xfaces.c: Remove unnecessary static decls.
4975 * xterm.c (updating_frame): Remove decl of nonexistent object.
4977 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4978 when building globals.h, as the objects that are not built on
4979 this host are not needed to compile C files on this host.
4981 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4983 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4985 * frame.h: Add missing prototype for x_wm_set_size_hint.
4987 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

4992 (Fsubstitute_command_keys):

4997 (make_buffer_string, make_buffer_string_both)
4998 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

5016 2012-09-02 Chong Yidong <cyd@gnu.org>
5018 * keymap.c (push_key_description): Print M-TAB as C-M-i
5021 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5023 * makefile.w32-in (CCL_H, W32FONT_H): New macros.

5033 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5034 more than one grapheme cluster passed to the shaper: compute the
5035 offset adjustment values separately for each cluster. (Bug#11860)
5037 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5038 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5039 about implicit conversions from integer to pointer.
5041 2012-09-01 Daniel Colascione <dancol@dancol.org>
5043 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

5097 window system declarations.
5099 * frame.h: Move common functions here: set_frame_menubar,
5100 x_set_window_size, x_sync, x_get_focus_frame,
5101 x_set_mouse_position, x_set_mouse_pixel_position,
5102 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5129 * lisp.h (mark_ttys): Remove prototype.
5130 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5131 to mark_ttys because all possible values of 'top_frame' slot are
5132 the frames which are reachable from Vframe_list.
5133 * term.c (mark_ttys): Remove.
5134 (init_tty): Safely initialize 'top_frame' slot with Qnil.
5136 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5138 Change struct frame bitfields from unsigned char to unsigned.

5158 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
5159 for GCC 4.7.1 x86-64.
5161 2012-08-30 Glenn Morris <rgm@gnu.org>
5163 * lread.c (init_lread): For out-of-tree builds, only add the
5164 source directory's site-lisp dir to the load-path if it exists,
5165 consistent with in-tree builds. (Bug#12302)
5167 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
5169 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

5184 (timeout_handler:): Set timer_fired to YES.
5185 (runDialogAt:): Set timer_fired to NO.
5186 Handle click on close button as quit.
5188 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5189 Add window_closed and button_values. Add void as return value for
5190 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5191 Add process_dialog as new member.
5193 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5195 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
5196 is not one of the heaps we manage. (Bug#12242)
5198 2012-08-28 Glenn Morris <rgm@gnu.org>
5200 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)

5396 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5397 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5398 are all boolean, so make them single-bit bitfields.
5400 * lisp.h (ASET): Remove attempt to detect side effects.
5401 It was meant to be temporary and it often doesn't work,
5402 because when IDX has side effects the behavior of IDX==IDX
5403 is undefined. See Stefan Monnier in
5404 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5406 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

5415 as that's faster and simpler than static storage. Don't bother
5416 with the g_main_context_query overhead if g_main_context_pending
5417 says no events are pending.
5418 (gfds, gfds_size): Remove these static vars.
5419 (xgselect_initialize): Remove; no longer needed.
5420 All uses and decls removed.
5422 * emacs.c (fatal_error_signal_hook): Remove.

5450 Use bool for booleans, instead of int.
5451 * lisp.h, process.h: Adjust prototypes to match above changes.
5452 * callint.c (Fcall_interactively): Don't assume the mark's
5453 offset fits in 'int'.

5466 Use bool for booleans, instead of int.
5467 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5468 since the 1-or-0 return value is always ignored anyway.
5469 (mmap_initialized_p):
5470 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5471 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5473 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5475 * bidi.c: Use bool for boolean.
5476 This is a bit more readable, and makes the text segment of bidi.o
5477 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5478 Presumably it's faster too.
5479 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5481 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5482 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
5483 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
5484 (bidi_explicit_dir_char, bidi_level_of_next_char)
5485 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5486 Use bool for booleans, instead of int.
5487 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5488 (bidi_unshelve_cache): Adjust decls to match code.
5490 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5492 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5495 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5497 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5498 * atimer.h: Include <stdbool.h>.
5500 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5502 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5503 compile time tests instead of run time tests on systems that do
5505 (FRAME_MAC_P): Remove leftover from deleted code.
5506 * frame.c (syms_of_frame): Remove leftover from deleted code.
5508 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5510 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5512 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5514 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5515 Otherwise, the compiler complains about (A?B:C) where B is void
5516 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5517 (fontset_add): Return void, for FONTSET_ADD.
5519 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5521 * alloc.c: Use bool for booleans.
5522 (gc_in_progress, abort_on_gc)
5523 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5524 (dont_register_blocks) [GC_MALLOC_CHECK]:
5525 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5526 (check_string_bytes, make_specified_string, memory_full)
5527 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5528 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5529 (mark_stack, valid_pointer_p, make_pure_string)
5530 (Fgarbage_collect, survives_gc_p, gc_sweep):
5531 Use bool for booleans, instead of int.
5532 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5533 Remove unused local.
5534 * alloc.c (PURE_POINTER_P):
5535 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5536 * editfns.c (Fformat):
5537 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5539 * fns.c (sweep_weak_table):
5540 * lisp.h (suppress_checking, push_message, survives_gc_p)
5541 (make_pure_string, gc_in_progress, abort_on_gc):
5542 * lread.c (readchar, read1):
5543 * print.c (Fprin1_to_string):
5544 * xdisp.c (push_message):
5545 Use bool for booleans affected directly or indirectly by
5548 Make recently-introduced setters macros.
5549 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5550 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5551 (set_fontset_default, set_fontset_fallback): Rename from their
5552 upper-case counterparts, and make them functions rather than macros.
5553 This is more consistent with the other recently-introduced setters.
5554 These don't need to be inline, since they're local.
5556 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5558 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5559 the loop (Bug#12247).
5561 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5563 * lisp.h (vcopy): Use memcpy rather than our own loop.
5564 This fixes a performance regression introduced by the recent
5565 addition of vcopy. This means 'vcopy' will need to be modified
5566 for a copying collector, but that's OK. Also, tighten the
5567 checking in the assertion.
5569 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5571 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5572 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5573 non-base glyph for the width of the base character, according to
5574 what x_draw_composite_glyph_string_foreground expects.
5575 Generate WADJUST value according to composition_gstring_width's
5576 expectations, to produce correct width of the composed character.
5577 Reverse the sign of the DU offset produced by ScriptPlace.
5579 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5581 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5583 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5585 Avoid direct writes to contents member of struct Lisp_Vector.
5586 * lisp.h (vcopy): New function to copy data into vector.
5587 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5588 * fns.c (Ffillarray): Use ASET.
5589 * keyboard.c (timer_check_2): Use AREF and ASET.
5590 (append_tool_bar_item, Frecent_keys): Use vcopy.
5591 * lread.c (read_vector): Use ASET.
5592 * msdos.c (Frecent_doskeys): Use vcopy.
5593 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5594 (Finternal_merge_in_global_face): Use ASET and vcopy.
5595 * xfont.c (xfont_list_pattern): Likewise.
5597 2012-08-21 Martin Rudalics <rudalics@gmx.at>
5599 * window.c (Fwindow_point): For the selected window always return
5600 the position of its buffer's point.
5601 (Fset_window_point): For the selected window always go in its
5602 buffer to the specified position.
5604 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5606 Setter macros for fontsets.
5607 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5608 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5609 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5612 2012-08-20 Glenn Morris <rgm@gnu.org>
5614 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5615 Don't assume that `ln -f' works.
5617 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5619 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5620 and later about non-assignments with no effect. See discussion at
5621 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5624 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5626 Inline setter functions for Lisp_Objects slots of struct specbinding.
5627 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5630 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5632 * window.c (select_window): Always make selected window's buffer
5635 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5637 Use AREF and ASET for docstrings of category tables.
5638 * category.h (CATEGORY_DOCSTRING): Use AREF.
5639 (SET_CATEGORY_DOCSTRING): Use ASET.
5640 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5642 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5644 Inline setter functions for hash table members.
5645 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5646 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5647 (set_hash_key_and_value, set_hash_index, set_hash_next)
5648 (set_hash_hash): New functions.
5649 * charset.c, fns.c: Adjust users.
5651 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5653 Inline getter and setter functions for per-buffer values.
5654 * buffer.h (per_buffer_default, set_per_buffer_default)
5655 (per_buffer_value, set_per_buffer_value): New functions.
5656 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5657 * buffer.c, data.c: Adjust users.
5659 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5661 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5663 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5665 Rely on <config.h> + <unistd.h> to declare 'environ',
5666 as gnulib does this if the system doesn't.
5667 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5668 Remove declaration. MS-Windows declares it on stdlib.h which is
5669 included by conf_post.h.
5670 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5671 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5672 * vm-limit.c: Include <unistd.h>, for 'environ'.
5674 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5675 (start_of_data): Remove decl; mem-limits.h provides it.
5677 * xdisp.c (handle_invisible_prop): Make it a bit faster
5678 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5680 2012-08-19 Chong Yidong <cyd@gnu.org>
5682 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5685 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5687 * .gdbinit: Use call instead of set when calling a function in the
5690 * data.c (set_internal): Don't use set_blv_found.
5691 (Fkill_local_variable): Likewise.
5693 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5695 * nsfont.m (ns_ascii_average_width): Ensure the string
5696 ascii_printable is initialized with a null-terminated character
5697 array. Otherwise, it can contain undesired extra characters.
5699 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5701 port new setting code to Sun C 5.8 2005/10/13
5702 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5703 Return void, not Lisp_Object. Otherwise, the compiler
5704 complains about (A?B:C) where B is void and C is Lisp_Object
5705 when compiling CHAR_TABLE_SET, due to the recent change to
5706 the API of sub_char_table_set_contents.
5708 2012-08-18 Chong Yidong <cyd@gnu.org>
5710 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5711 for the string case (Bug#3874).
5713 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5715 * buffer.h (BSET): Remove (Bug#12215).

5864 "CSET (XCHAR_TABLE (char_table), parent, parent);" with
5865 "set_char_table_parent (char_table, parent);".
5866 The old version was confusing because it used the same name
5867 'parent' for two different things.
5869 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
5871 Functions to get and set Lisp_Object fields of buffer-local variables.

5880 font spec, make the font's attributes take precedence over
5881 directly-specified attributes.
5882 (merge_face_ref): Recognize :font.
5884 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
5886 Do not use memcpy for copying intervals.
5887 * intervals.c (reproduce_interval): New function.

6538 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6539 * w32.c (init_environment): Change the default values of many
6540 environment variables in dflt_envvars[] to NULL, to avoid pushing
6541 them into environment when they were not already defined.
6542 Remove the code that deletes site-lisp subdirectories from the default
6543 value of EMACSLOADPATH, as it is no longer needed.
6544 (check_windows_init_file): Now external, not static.
6545 Use Vload_path as is, without adding anything, as this function is now
6546 called when Vload_path is already set up.
6548 * w32.h (check_windows_init_file): Add prototype.
6550 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6557 installation tree, as appropriate.
6559 * callproc.c (init_callproc_1): Call decode_env_path instead of
6560 doing its equivalent by hand.

6562 the code that sets Vexec_path run on MS-Windows.
6564 * lread.c (init_lread): Add comments to #ifdef's.
6566 * msdos.c (dos_set_window_size, IT_update_begin)

6593 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6594 Remove unnecessary pointer casts.
6595 * alloc.c (record_xmalloc): New function.
6596 * lisp.h (record_xmalloc): New decl.
6597 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6598 more like a function. This is because the pointer cast is not
6599 needed. All uses changed.
6600 * print.c (print_string, print_error_message): Avoid length recalc.
6602 Improve fix for macroexp crash with debugging (Bug#12118).
6603 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6604 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6605 not supposed to be invoked from the garbage collector.
6606 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
6607 (gc_aset): New function, which is like ASET but can be
6608 used in the garbage collector.

6624 headers (most versions of MinGW w32api don't).
6625 (get_security_info, create_symbolic_link)
6626 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

6633 have the required privileges.
6634 (get_file_security_desc_by_name): Rename from
6635 get_file_security_desc.

6637 with addition of handling of symlinks and support for 'lstat'.
6638 If possible, get file's attributes and security information by
6639 handle, not by name. Produce S_IFLNK bit for symlinks, when
6640 called from 'lstat'.
6641 (stat, lstat): New functions, call 'stat_worker'.
6642 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6643 symlinks when the underlying filesystem supports them.
6645 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6647 Fix macroexp crash on Windows with debugging (Bug#12118).
6648 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6649 checking subscripts; problem introduced with the recent
6650 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6651 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6652 since it's used in non-static inline functions now.
6654 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6655 Don't assume buffer size fits in 'int'. Remove unused local.

6672 * category.c (CATEGORY_INLINE):
6673 * character.c (CHARACTER_INLINE):
6674 * charset.c (CHARSET_INLINE):
6675 * composite.c (COMPOSITE_INLINE):
6676 * dispnew.c (DISPEXTERN_INLINE):
6677 * sysdep.c (SYSTIME_INLINE):
6678 Define to EXTERN_INLINE, so that the corresponding functions
6679 are compiled into code.
6680 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6681 (INLINE_HEADER_END): New macros.
6682 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6702 hard-coding the path separator.
6704 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6706 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6707 This how ASET and AREF are supposed to work, and makes
6708 it easier to think about future improvements. See
6709 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6710 * charset.h (set_charset_attr): New function.

7202 the fix for 12036 would have avoided some of the problems noted in
7203 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7204 would have been more obvious.

7214 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7215 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7216 not be usable in #if. This simplifies things.
7218 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7220 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7226 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7227 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7228 Adjust to changes in lisp.h and emacs.c, by using
7229 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead

8141 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8142 * nsterm.m (ns_term_init):
8143 Avoid the need for strncpy, by using build_string or
8144 make_unibyte_string directly. Use dtoastr, not snprintf.
8145 * process.c (Fmake_network_process): Diagnose service names that
8146 are too long, rather than silently truncating them or creating
8147 non-null-terminated names.
8148 (Fnetwork_interface_info): Likewise, for interface names.
8149 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8150 Prefer sprintf to strncat.
8151 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

8177 Optimize pure C strings initialization.
8178 * lisp.h (make_pure_string): Fix prototype.
8179 (build_pure_c_string): New function, defined as static inline. This
8180 provides a better opportunity to optimize away calls to strlen when
8181 the function is called with compile-time constant argument.
8182 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8183 argument, adjust users accordingly. Use build_pure_c_string where
8185 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8186 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8187 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8189 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8191 Avoid calls to strlen in miscellaneous functions.
8192 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8193 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8194 * lread.c (openp): Likewise.
8196 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8198 Avoid calls to strlen in path processing functions.
8199 * fileio.c (file_name_as_directory): Add comment. Change to add
8200 srclen argument and return the length of result. Adjust users

8204 Adjust users accordingly.
8205 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8207 2012-07-10 Glenn Morris <rgm@gnu.org>

8214 * s/gnu.h (DATA_START): Move definitions to configure.
8216 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8217 We include usg5-4-common.h, which defines them both.
8219 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8220 O_RDONLY already includes it).
8222 Stop ns builds setting the EMACSLOADPATH environment variable.
8223 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8224 Now it does not set EMACSLOADPATH, just returns the load-path string.
8225 * nsterm.h: Update accordingly.
8226 * lread.c [HAVE_NS]: Include nsterm.h.
8227 (init_lread) [HAVE_NS]: Use ns_load_path.

8230 2012-07-09 Glenn Morris <rgm@gnu.org>
8232 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8233 since the included bsd-common.h does so.
8235 Stop ns builds setting the EMACSPATH environment variable.
8236 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8237 (ns_init_paths): Do not set EMACSPATH.
8238 * nsterm.h (ns_exec_path): Add it.
8239 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8242 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8244 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8246 * process.c (wait_reading_process_output): 'waitchannels' was unset
8247 when read_kbd || !NILP (wait_for_cell); fix this.
8249 Add GCC-style 'const' attribute to functions that can use it.
8250 * character.h (char_resolve_modifier_mask):
8251 * keyboard.h (make_ctrl_char):
8252 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

8261 Add decls with ATTRIBUTE_CONST.
8263 Minor improvements to make_formatted_string.
8264 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8265 where int is good enough, as vsprintf returns an int.
8266 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8268 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8270 Use make_formatted_string to avoid double length calculation.
8271 * lisp.h (make_formatted_string): New prototype.

8295 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8297 Move marker debugging code under MARKER_DEBUG.
8298 * marker.c (MARKER_DEBUG): Move marker debugging code under
8299 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8300 for bootstrap with --enable-checking (~3x slowdown reported
8301 by Juanma Barranquero <lekktu@gmail.com>).
8302 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8304 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8306 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8307 See <http://bugs.gnu.org/11825#29>.
8309 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8311 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8312 has no font, use the frame's font. (Bug#11813)
8313 (display_line): Add commentary about displaying truncation glyphs
8315 (produce_special_glyphs): Move here from term.c.
8317 * term.c (produce_special_glyphs): Move to xdisp.c.
8319 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8322 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8324 * xdisp.c (display_line): Avoid warning about implicit declaration
8327 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8329 * lisp.h: Remove empty conditional.
8331 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8333 * lread.c (load_path_check): Now static.
8335 Fix some minor --with-ns problems found by static checking.
8336 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8337 (x_set_font) [!HAVE_X_WINDOWS]:
8338 * image.c (xpm_load_image) [HAVE_NS]:
8339 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8340 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8341 Remove unused local.
8342 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8343 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8344 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8345 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8346 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8347 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8348 Fix pointer signedness problem.
8349 * xfaces.c (FRAME_X_FONT_TABLE):
8350 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8352 2012-07-07 Glenn Morris <rgm@gnu.org>
8354 * lread.c (load_path_check): New function, split from init_lread.
8355 (init_lread): Reorganize. Motivation:
8356 If EMACSLOADPATH is set, check/warn about that rather than the
8357 defaults, which we are not going to use. Hence we can remove
8358 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8359 Don't warn if site-lisp directories are missing.
8360 If not installed, start from a blank load-path, since
8361 PATH_LOADSEARCH refers to the eventual installation directories.
8363 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8365 Support truncation and continuation glyphs on GUI frames, when
8366 fringes are disabled. (Bug#11832)
8367 * xdisp.c (init_iterator): Get dimensions of truncation and
8368 continuation glyphs even if on GUI frames.
8369 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8370 or both, are absent.
8371 (start_display, move_it_in_display_line_to): Handle the case of a
8372 GUI frame without a fringe to display continuation or truncation
8374 (insert_left_trunc_glyphs): Support GUI frames: make sure
8375 truncation glyphs overwrite enough glyphs from the current line to
8376 have sufficient space in pixels.
8377 (display_line): Support truncation and continuation glyphs on GUI
8378 frames. If some spare pixels are left on the line after inserting
8379 the truncation glyphs, fill that space with a stretch glyph of a
8380 suitably computed width.
8382 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8383 produce_glyphs, to support GUI sessions.
8385 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8387 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8389 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8391 Do not require float-time's arg to fit in time_t (Bug#11825).
8392 This works better on hosts where time_t is unsigned, and where
8393 float-time is applied to the (negative) difference between two times.
8394 * editfns.c (decode_time_components): Last arg is now double *,
8395 not int *, and means to store all the result as a double, without
8396 worrying about whether the seconds part fits in time_t.
8397 All callers changed.
8398 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8399 All callers changed.
8400 (Ffloat_time): Do not fail merely because the specified time falls
8401 outside of time_t range.
8403 2012-07-07 Glenn Morris <rgm@gnu.org>
8405 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8411 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8412 Update dependencies.
8414 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8416 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8418 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

8420 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8421 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8422 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

8425 * xfont.c (compare_font_names): Redo to omit the need for casts.
8427 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8429 * xfns.c (Fx_change_window_property): Doc fix.
8430 * w32fns.c (Fx_change_window_property): Doc fix.
8432 * w32fns.c (Fx_window_property): Accept the same arguments as the
8433 X Windows version. Doc fix.
8434 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8436 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8437 Eli Zaretskii <eliz@gnu.org>
8439 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8440 Windows-specific code from nt/config.nt moved here.
8441 Obsolete settings removed.
8443 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8445 * process.c: Avoid unnecessary calls to gettime.
8446 (wait_reading_process_output): Don't get the time of day
8447 when gobbling data immediately and not waiting, as there's no need
8448 for it in that case. This removes a FIXME.
8450 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8452 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8453 is defined (Bug#11768).
8455 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8457 Fix marker debugging code.
8458 * marker.c (byte_char_debug_check): Do not perform the check
8459 if buffer is not multibyte.
8460 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8461 Call byte_char_debug_check with correct arguments.
8463 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8465 Compile marker debugging code only if ENABLE_CHECKING is defined.
8466 * marker.c (byte_char_debug_check, count_markers):
8467 Use only if ENABLE_CHECKING is defined.
8468 (byte_debug_flag): Remove.
8469 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8470 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8472 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8474 Avoid code repetition in marker-related functions.
8475 * marker.c (attach_marker): New function.
8476 (Fset_marker, set_marker_restricted, set_marker_both)
8477 (set_marker_restricted_both): Use it.
8478 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8479 Consistently rename charno to charpos.
8480 (marker_position): Add eassert.
8481 (marker_byte_position): Convert to eassert.

8500 * window.c (save_window_save): Likewise.
8502 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8504 Do not use Fdelete_overlay in delete_all_overlays
8505 to avoid redundant calls to unchain_overlay.
8506 * buffer.c (drop_overlay): New function.
8507 (delete_all_overlays, Fdelete_overlay): Use it.
8508 * minibuf.c (get_minibuffer): Fix comment.
8510 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8512 Port to OpenBSD 5.1 amd64.
8513 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8514 This is needed for OpenBSD, and should be harmless on all BSD systems.
8515 Also, include <sys/sysctl.h>, as it should be available on all
8516 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8517 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8518 use p_pid member, not kp_proc.pid.
8520 2012-07-06 Glenn Morris <rgm@gnu.org>
8522 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8524 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8526 More xmalloc and related cleanup.
8527 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
8528 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

8533 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
8534 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
8535 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8537 Omit needless casts involving void * pointers and allocation.
8538 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8539 as the former is more robust if P's type is changed.
8540 Prefer xzalloc to xmalloc + memset 0.
8541 Simplify malloc-or-realloc to realloc.
8542 Don't worry about xmalloc returning a null pointer.
8543 Prefer xstrdup to xmalloc + strcpy.
8544 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8546 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8547 alloca of a constant.
8549 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8551 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8552 hscroll is larger than the line width. Fixes long and futile
8553 looping inside extend_face_to_end_of_line (on a TTY) producing
8554 glyphs that are not needed and thrown away.
8556 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8558 * marker.c (set_marker_restricted_both): Simplify by using
8561 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

8572 followed by gtk_box_set_homogeneous (Bug#11768).
8573 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8574 (update_theme_scrollbar_width, xg_create_scroll_bar):
8575 Use gtk_scrollbar_new (Bug#11768).
8576 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

8584 * xdisp.c (window_hscroll_limited): New function.
8585 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8586 coordinates when window's hscroll is set to insanely large
8589 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8591 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
8592 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
8594 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8597 * lisp.h (xzalloc): New prototype. Omit needless casts.
8598 * alloc.c (xzalloc): New function. Omit needless casts.

8652 * fileio.c (time_error_value): Check the right error number.
8653 Problem reported by Troels Nielsen in
8654 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8656 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8658 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8659 This should be fixed in a better way; see Eli Zaretskii in
8660 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8661 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8663 * fileio.c (time_error_value): Rename from special_mtime.
8664 The old name's problems were noted by Eli Zaretskii in
8665 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8667 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8668 This variable's comment says Emacs needs at least one GDB-visible
8669 symbol of type enum pvec_type, to work around GDB problems.
8670 The symbol's value doesn't matter.
8672 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8673 that causes compilation to fail on pre-C99 compilers.
8675 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8677 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
8678 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
8680 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8682 * buffer.c (init_buffer_once): Fix initialization of
8683 headers for buffer_defaults and buffer_local_symbols.
8684 Reported by Juanma Barranquero <lekktu@gmail.com>.
8686 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8688 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8689 * lisp.h (enum pvec_type): Use fewer bits.
8690 (PSEUDOVECTOR_SIZE_BITS): New constant.
8691 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8692 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8693 change in pvec_type.
8694 (PSEUDOVECTOR_TYPEP): New macro.
8695 (TYPED_PSEUDOVECTORP): Use it.
8696 * fns.c (internal_equal): Adapt code to extract pvectype.

8698 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
8699 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
8700 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8701 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8702 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8703 abusing vector->header.next.nbytes.
8704 (live_vector_p): Use PVEC_TYPE.
8705 (mark_object): Adapt code to extract pvectype. Use switch.
8707 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8709 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8710 Tighten new eassert a bit.
8712 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8714 Fix compilation with --enable-gcc-warnings and -O1
8716 * doprnt.c (doprnt): Change type of tem to int, initialize
8717 to avoid compiler warning. Add eassert.
8718 * search.c (simple_search): Initialize match_byte to avoid
8719 compiler warning. Add eassert.
8721 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8723 Avoid weird behavior with large horizontal scrolls.
8724 Without this change, for example, large hscroll values would
8725 mess up Emacs's display on Fedora 15 x86, presumably due to
8726 overflows in int calculations in the display code.
8727 Also, if buffers had long lines, Emacs would freeze.
8728 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8729 (set_window_hscroll): New function, containing the old guts of
8730 Fset_window_hscroll. Return the clipped value.
8731 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8732 This avoids the need to check against PTRDIFF_MAX.
8734 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8736 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8738 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8740 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8742 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8743 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8744 since GCC 4.4.6 issues a bogus warning for them.
8746 Fix bugs in file timestamp newness comparisons.
8747 * fileio.c (Ffile_newer_than_file_p):
8748 * lread.c (Fload): Use full timestamp resolution of files,
8749 not just the 1-second resolution, so that files that are only
8750 slightly newer still count as newer.
8751 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8752 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8754 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8756 * fileio.c: Improve handling of file time marker. (Bug#11852)
8757 (special_mtime): New function.
8758 (Finsert_file_contents, Fverify_visited_file_modtime):
8759 Use it to set special mtime values consistently.
8761 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8763 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8764 marker for non-existing file. (Bug#11852)
8766 2012-07-03 Glenn Morris <rgm@gnu.org>
8768 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8769 and did not make it into globals.h).
8771 2012-07-03 Tom Tromey <tromey@redhat.com>
8773 * window.c (Fset_window_margins, Fset_window_fringes)
8774 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8775 * textprop.c (Fprevious_property_change): No longer static.
8776 * syntax.c (Fsyntax_table_p): No longer static.
8777 * process.c (Fget_process, Fprocess_datagram_address): No longer

8798 * intervals.h: Remove EXFUNs.
8799 * fontset.h: Remove EXFUN.

8805 * window.h: Remove EXFUNs.

8807 * xterm.h: Remove EXFUN.
8809 2012-07-03 Glenn Morris <rgm@gnu.org>
8811 * lisp.h (Frandom): Make it visible to C.
8812 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8813 buffer for invisible buffers. (Bug#1229)
8815 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8817 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8818 values which aren't power of 2.
8819 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8820 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8823 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8825 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8827 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8829 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8831 * alloc.c (allocate_vector_block): Remove redundant
8832 calls to mallopt if DOUG_LEA_MALLOC is defined.
8833 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8834 avoid calls to mallopt if zero_vector is returned.
8836 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8838 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8839 is enabled, avoid dereferencing NULL current_sblock if
8842 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8844 Cleanup basic buffer management.
8845 * buffer.h (struct buffer): Change layout to use generic vector
8846 marking code. Fix some comments. Change type of 'clip_changed'
8847 to bitfield. Remove unused #ifndef old.
8848 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8849 (GET_OVERLAYS_AT): Fix indentation.
8850 (for_each_per_buffer_object_at): New macro.

8854 * alloc.c (allocate_buffer): Adjust to match new layout of
8855 struct buffer. Fix comment.
8856 (mark_overlay): New function.

8859 (mark_object): Use it. Adjust marking of misc objects
8860 and related comments.
8862 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8864 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8865 wrapper that is not needed because the wrapped code is a no-op (zero
8866 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8867 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8869 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8871 * alloc.c (mark_buffer): Simplify. Remove prototype.
8872 (mark_object): Add comment. Reorganize marking of vector-like
8873 objects. Use CHECK_LIVE for all vector-like objects except buffers
8874 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8875 Avoid redundant calls to mark_vectorlike for bool vectors.
8877 2012-06-30 Glenn Morris <rgm@gnu.org>
8879 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8881 * epaths.in (PATH_SITELOADSEARCH): New.
8882 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8883 This is rather than relying on --enable-locallisppath elements
8884 having "site-lisp" in their names. (Bug#10208#25, 11658)
8886 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8888 * w32proc.c (sys_select): Accept and ignore one more argument.
8890 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8892 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8893 (pselect) [!MS_DOS]: Redirect to sys_select.
8895 * sysdep.c: Don't include dos.h and dosfns.h.
8897 * process.c (sys_select):
8898 * msdos.c (sys_select): Accept one more argument and ignore it.
8900 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8901 adapt data types and code to that.
8904 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8905 which clashes with the gnulib function of the same name.
8907 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8909 * font.c (font_style_to_value, font_style_symbolic)
8910 (font_prop_validate_style): Add type checks for values in
8913 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8915 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8918 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8920 * xdisp.c (try_window_id): Undo last change.
8922 * w32.c (getwd): Adjust commentary about startup_dir.
8923 (init_environment): Always call sys_access, even in non-MSVC
8924 builds. Don't chdir to the directory of the Emacs executable.
8925 This undoes code from 1997 which was justified by the need to
8926 "avoid conflicts when removing and renaming directories". But its
8927 downside was that every relative file name was being interpreted
8928 relative to the directory of the Emacs executable, which can never
8929 be TRT. In particular, it broke sys_access when called with
8930 relative file names.
8931 (sys_access): Map GetLastError to errno.
8933 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8935 * window.h (struct window): Change type of 'fringes_outside_margins'

8939 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8942 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8944 * gnutls.c (emacs_gnutls_handshake):
8945 Add QUIT to make the loop interruptible.
8947 2012-06-29 Glenn Morris <rgm@gnu.org>
8949 * charset.c (init_charset): Make lack of etc/charsets fatal.
8951 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8953 * editfns.c (region_limit): Fix type mismatch.
8955 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8957 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8958 undefined. Convert from xassert to eassert.
8959 * nsmenu.m: Convert from xassert to eassert.
8960 * nsterm.m: Likewise.
8962 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8964 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8966 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8968 Avoid integer overflow on scroll-left and scroll-right.
8969 * window.c (HSCROLL_MAX): New macro.
8970 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8971 overflow when requested scroll falls outside ptrdiff_t range.
8973 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8975 * window.h (struct window): Change type of 'hscroll',
8976 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8977 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8978 Adjust users accordingly.
8979 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8980 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8981 from EMACS_INT to ptrdiff_t.
8982 (make_window): Omit redundant initialization.
8984 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
8986 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
8988 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8990 * window.h (struct window): Change type of 'use_time' and
8991 'sequence_number' from Lisp_Object to int.
8992 * frame.c (make_frame): Adjust users accordingly.

9001 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9002 adjust comments accordingly.

9053 avoid GCC warning about unused macro.
9055 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9057 * alloc.c (allocate_string): Omit intervals initialization.
9058 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9059 as in make_pure_string and make_pure_c_string.
9061 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9063 * alloc.c (allocate_string): Fix last change.
9065 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9120 * w32proc.c (sys_spawnve): Likewise.
9121 * xterm.c (x_term_init): Likewise.
9123 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9125 Use sprintf return value instead of invoking strlen on result.
9126 In the old days this wasn't portable, since some sprintf
9127 implementations returned char *. But they died out years ago and
9128 Emacs already assumes sprintf returns int.
9129 Similarly for float_to_string.
9130 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9131 * ccl.c (ccl_driver):
9132 * character.c (string_escape_byte8):

9135 * print.c (print_object):
9136 * xdisp.c (message_dolog):
9137 * xfns.c (syms_of_xfns):
9138 Use sprintf or float_to_string result to avoid need to call strlen.
9139 * data.c (Fnumber_to_string):
9140 Use make_unibyte_string, since the string must be ASCII.
9141 * lisp.h, print.c (float_to_string): Now returns int length.
9142 * term.c (produce_glyphless_glyph):
9143 Use sprintf result rather than recomputing it.
9145 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9146 * Makefile.in (ALL_CFLAGS):
9147 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9148 * gmalloc.c, regex.c: Include <config.h> unconditionally.

9152 * dispextern.h (xstrcasecmp): Define to library function
9153 strcasecmp if available.

9169 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9171 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9172 sprintf already null-terminates its output.
9174 * xfns.c (x_window): Remove redundant cast.
9176 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9178 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9179 `const char *' to `char *' to avoid compiler warning.
9181 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9183 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9184 instead of truncating it to 63 (admittedly a generous limit).
9186 * process.c: Fix spelling and caps in comments.
9188 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9190 * emacs.c (setpgrp): Remove definition, unused.

9237 Remove unnecessary forward decls.
9239 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9241 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

9243 * dispnew.c (Fsleep_for, sit_for):
9244 * keyboard.c (kbd_buffer_get_event):
9245 * process.c (Faccept_process_output):
9246 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9247 This improves on the previous patch, which introduced a bug
9248 when time_t is unsigned and as wide as intmax_t.
9249 See <http://bugs.gnu.org/9000#51>.
9251 2012-06-23 Eli Zaretskii <eliz@gnu.org>

9267 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9268 Privately reported by Herbert J. Skuhra.
9269 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9271 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9272 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9274 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9276 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9277 last argument of make_unibyte_string.
9279 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9280 language ID in the event parameters.
9282 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9283 event.code, not the obscure "character set ID".

9306 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9307 Privately reported by Herbert J. Skuhra.

9314 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9316 Support higher-resolution time stamps (Bug#9000).
9317 The time stamps are only nanosecond-resolution at the C level,
9318 since that's the best that any real-world system supports now.
9319 But they are picosecond-resolution at the Lisp level, as that's
9320 easy, and leaves room for future OS improvements.
9322 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9325 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9326 Don't get current time unless it's needed.
9328 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9329 now provides it if it's absent.
9330 (start_atimer): Port to higher-res time stamps.
9331 Check for time stamp overflow. Don't get current time more
9332 often than is needed.
9334 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9335 Include systime.h, not time.h.
9336 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9338 * dired.c: Include stat-time.h.
9339 (Ffile-attributes): File times now have higher resolution.
9341 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9342 (struct image): Timestamp now has higher resolution.
9344 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9345 has at least microseconds now. All uses removed.
9346 (update_frame, update_single_window, update_window, update_frame_1)
9347 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9348 (duration_to_sec_usec): Remove; no longer needed.
9350 * editfns.c (time_overflow): Now extern.
9351 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9352 (float-time, Fformat_time_string, Fcurrent_time_string)
9353 (Fcurrent_time_zone): Accept and generate higher-resolution
9355 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9356 (decode_time_components, lisp_seconds_argument): New functions.
9357 (make_time): Now static.
9358 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9359 Report an error if the time is invalid, rather than having the caller
9362 * fileio.c: Include <stat-time.h>
9363 (Fcopy_file): Copy higher-resolution time stamps.
9364 Prefer to set the time stamp via a file descriptor if that works.
9365 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9366 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9367 (Fvisited_file_modtime, Fset_visited_file_modtime):
9368 Support higher-resolution time stamps.
9370 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9372 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9374 * image.c (prepare_image_for_display, clear_image_cache)
9375 (lookup_image): Port to higer-resolution time stamps.
9377 * keyboard.c (start_polling, bind_polling_period):
9378 Check for time stamp overflow.
9379 (read_char, kbd_buffer_get_event, timer_start_idle)
9380 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9381 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9382 Port to higher-resolution time stamps. Do not assume time_t is signed.
9383 (decode_timer): New function. Timers are now vectors of length 9,
9384 not 8, to accommodate the picosecond component.
9385 (timer_check_2): Use it.
9387 * nsterm.m (select_timeout, timeval_subtract): Remove.
9388 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9389 as they're a bit more accurate and handle overflow better.
9390 (ns_select): Change prototype to be compatible with pselect.
9391 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9392 * nsterm.h (ns_select): Adjust prototype.
9394 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9395 us-resolution time stamps.
9396 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9398 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9400 * lisp.h (time_overflow): New decl.
9401 (wait_reading_process_output): First arg is now intmax_t, not int,
9402 to accommodate larger waits.
9404 * process.h (struct Lisp_Process.read_output_delay):
9405 Now counts nanoseconds, not microseconds.
9406 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9408 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9409 (wait_reading_process_output):
9410 Port to ns-resolution time stamps.
9411 (Faccept_process_output, wait_reading_process_output):
9412 Check for time stamp overflow. Do not assume time_t is signed.
9413 (select_wrapper): Remove; we now use pselect.
9414 (Fprocess_attributes): Now generates ns-resolution time stamps.
9416 * sysdep.c: Include utimens.h. Don't include utime.h
9417 or worry about struct utimbuf; gnulib does that for us now.
9418 (gettimeofday): Remove; gnulib provides a substitute.
9419 (make_timeval): New function.
9420 (set_file_times): Now sets ns-resolution time stamps.
9421 New arg FD; all uses changed.
9422 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9423 (system_process_attributes):
9424 Now returns ns-resolution time stamp. All uses changed.
9425 Check for time stamp overflow.
9427 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9428 provides a substitute now.
9430 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9431 since it guarantees struct timespec.
9432 (EMACS_TIME): Now struct timespec, so that we can support
9433 ns-resolution time stamps.
9434 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9435 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9436 (EMACS_USECS): Remove.
9437 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9438 so multiply the arg by 1000 before storing it.
9439 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9441 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9442 Port to ns-resolution time stamps.
9443 (EMACS_TIME_NEG_P): Remove; replaced by....
9444 (EMACS_TIME_SIGN): New macro.
9445 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9446 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
9447 (set_file_times, make_time, lisp_time_argument): Adjust signature.
9448 (make_timeval, make_lisp_time, decode_time_components): New decls.
9449 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9450 that it mishandled time_t overflow. You can't compare by subtracting!
9451 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9452 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9454 * term.c: Include <sys/time.h>.
9455 (timeval_to_Time): New function, for proper overflow wraparound.
9456 (term_mouse_position, term_mouse_click): Use it.
9458 * undo.c (record_first_change): Support higher-resolution time stamps
9460 (Fprimitive_undo): Use them when restoring time stamps.
9462 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9463 (w32_get_internal_run_time):
9464 Port to higher-resolution Emacs time stamps.
9465 (ltime): Now accepts single 64-bit integer, as that's more convenient
9468 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9470 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9471 for compatibility with pselect. Support ns-resolution time stamps.
9473 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9475 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9476 Check for time stamp overflow, and support ns-resolution time stamps.
9478 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9479 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9480 (timeval_subtract): Remove; no longer needed.
9481 (XTflash, XTring_bell, x_wait_for_event):
9482 Port to ns-resolution time stamps. Don't assume time_t is signed.
9484 2012-06-22 Chong Yidong <cyd@gnu.org>
9486 * xdisp.c (x_consider_frame_title): Revert last change.
9488 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9490 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9491 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9492 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9493 staticidx goes up to 1597 out of 1600 = 0x640.)
9495 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9497 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9498 Otherwise, the umask might be mistakenly 0 while handling input signals.
9500 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
9502 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

9507 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
9508 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
9509 access to `contents' member of Lisp_Vector objects with AREF and ASET
9512 2012-06-19 Chong Yidong <cyd@gnu.org>
9514 * frame.c (delete_frame): When selecting a frame on a different
9515 text terminal, do not alter the terminal's top-frame.

9518 frame's selected window and its terminal's top-frame.
9519 (unwind_format_mode_line): Restore them.
9520 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9522 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9523 since tty frames can be explicitly named.
9524 (prepare_menu_bars): Likewise.
9526 * term.c (Ftty_top_frame): New function.
9528 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9530 Port byte-code-meter to modern targets.
9531 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9532 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9533 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9534 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
9535 (METER_1, METER_2): Simplify.

9765 code works fine either way, and efficiency is not a concern here,
9766 as the union type is for debugging, not for production.
9767 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9768 Use an inline function on all platforms when using the union type,
9769 since this is simpler and 'static inline' can be used portably

9913 * doprnt.c (doprnt): Truncate multibyte char correctly.
9914 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9915 would mishandle a string argument "Xc" if X was a multibyte
9916 character of length 2: it would truncate after X's first byte
9917 rather than including all of X.

10000 and 'double' in a couple of places.
10002 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10004 * xdisp.c (handle_stop): Detect whether we have overlay strings
10005 loaded by testing it->current.overlay_string_index to be
10006 non-negative, instead of checking whether n_overlay_strings is
10007 positive. (Bug#11587)

10017 * search.c (search_buffer): Remove calls to
10018 r_alloc_inhibit_buffer_relocation, as it is now called by
10019 maybe_unify_char, which was the cause of relocation of buffer text
10022 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10024 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10025 for the duration of call to load_charset, to avoid problems with
10026 callers of maybe_unify_char that access buffer text through C
10029 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10030 decrement the inhibition flag, instead of just setting or
10033 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10035 Remove obsolete '#define static' cruft.
10036 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10037 This #undef was "temporary" in 2000; it is no longer needed
10038 now that '#define static' has gone away.
10039 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10040 (gray_bitmap_bits): Remove; no longer needed.
10041 All uses replaced with definiens.
10042 * xterm.c: Include "bitmaps/gray.xbm".
10044 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10046 Clean up __executable_start, monstartup when --enable-profiling.
10047 The following changes affect the code only when profiling.
10048 * dispnew.c (__executable_start): Rename from safe_bcopy.
10049 Define only on platforms that need it.
10050 * emacs.c: Include <sys/gmon.h> when profiling.
10051 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10052 (__executable_start): Remove decl, since lisp.h does it now.
10053 (safe_bcopy): Remove decl; no longer has that name.
10054 (main): Coalesce #if into single bit of code, for simplicity.
10055 Cast pointers to uintptr_t, since standard libraries want integers
10057 * lisp.h (__executable_start): New decl.
10059 2012-05-31 Glenn Morris <rgm@gnu.org>
10061 * image.c (Fimagemagick_types): Doc fix.
10063 2012-05-30 Jim Meyering <meyering@redhat.com>
10065 * callproc.c (Fcall_process_region): Include directory component
10066 in mkstemp error message (Bug#11586).
10068 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10070 * alloc.c, lisp.h (make_pure_vector): Now static.
10072 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
10074 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
10075 Move to byte-run.el.
10076 (Fautoload): Do the hash-doc more carefully.
10077 * data.c (Fdefalias): Purify definition, except for keymaps.
10078 (Qdefun): Move from eval.c.
10079 * lisp.h (Qdefun): Remove.
10080 * lread.c (read1): Tiny simplification.
10082 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10084 Do not create empty overlays with the evaporate property (Bug#9642).
10085 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10086 Bug#9642, but explicitly check that the buffer the overlay would
10087 be moved to is live and rearrange lines to make sure that errors
10088 will not put the overlay in an inconsistent state.
10089 (Fdelete_overlay): Cosmetics.
10091 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10093 * w32term.c (my_bring_window_to_top): New function.
10094 (x_raise_frame): Use handle returned by DeferWindowPos, which
10095 could be different from the original one.
10096 Call my_bring_window_to_top instead of my_set_foreground_window.

10105 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10107 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10108 This avoids undefined behavior that might cause the eassert
10109 to not catch an out-of-range value.
10111 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10113 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10114 Update dependencies.
10116 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10118 * bidi.c (bidi_mirror_char): Fix last change.
10120 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
10122 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
10123 when referring to sectname field in printf format.
10125 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10127 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10128 Only r_alloc_inhibit_buffer_relocation needed to be added;
10129 the others were already declared.
10131 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10132 before checking whether it's out of range. Put the check inside
10134 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10136 2012-05-27 Ken Brown <kbrown@cornell.edu>
10138 * callproc.c (Fcall_process): Restore a line that was accidentally
10139 commented out in the 2011-02-13 change (bug#11547).
10141 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10143 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10144 defined on ralloc.c.
10146 * buffer.c [REL_ALLOC]: Remove prototypes of
10147 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10148 they are now on lisp.h.
10150 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10152 * search.c (search_buffer): Use it to inhibit relocation of buffer
10153 text while re_search_2 is doing its job, because re_search_2 is
10154 passed C pointers to buffer text. (Bug#11519)
10156 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10157 Update value to 24.
10159 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10160 state after an additional call to move_it_in_display_line_to, keep
10161 the values of it->max_ascent and it->max_descent found for the
10163 (pos_visible_p): Revert the comparison against bottom_y to what it
10164 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10167 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10169 Fix coding-related core dumps with gcc -ftrapv.
10170 The code was computing A - B, where A and B are pointers, and B is
10171 random garbage. This can lead to core dumps on platforms that
10172 have special pointer registers, and it also leads to core dumps on
10173 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10174 A - B only when B is initialized properly.
10175 * coding.c (coding_set_source, coding_set_destination): Return void.
10176 (coding_change_source, coding_change_destinations): New functions,
10177 with the old behaviors of coding_set_source and coding_set_destination.
10178 All callers that need an offset changed to use these new functions.
10180 2012-05-26 Glenn Morris <rgm@gnu.org>
10182 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
10184 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10186 Extend mouse support on W32 text-mode console.
10187 * xdisp.c (draw_row_with_mouse_face):
10188 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10190 * w32console.c: Include window.h.
10191 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10193 (initialize_w32_display): Initialize mouse-highlight data.
10195 * w32inevt.c: Include termchar.h and window.h.
10196 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10197 moves, call note_mouse_highlight. If help_echo changed, call
10198 gen_help_event to produce help-echo message in the echo area.
10199 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10202 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10204 * lread.c (read1): Simplify slightly to avoid an overflow warning
10205 with GCC 4.7.0 on x86-64.
10207 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10209 * bidi.c (bidi_mirror_char): Revert last change: an int is
10210 definitely wide enough here.
10212 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10214 Fix integer width and related bugs (Bug#9874).
10215 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
10216 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
10217 (string_bytes, check_sblock, allocate_string_data):
10218 (compact_small_strings, Fmake_bool_vector, make_string)
10219 (make_unibyte_string, make_multibyte_string)
10220 (make_string_from_bytes, make_specified_string)
10221 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10222 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10224 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10225 (allocate_pseudovector):
10226 Use int, not EMACS_INT, where int is wide enough.
10227 (inhibit_garbage_collection, Fgarbage_collect):
10228 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10229 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10230 int might not be wide enough.
10231 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10232 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10233 (bidi_at_paragraph_end, bidi_find_paragraph_start)
10234 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
10235 (bidi_level_of_next_char, bidi_move_to_visually_next):
10236 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10237 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
10238 (Fkill_buffer, Fset_buffer_major_mode)
10239 (advance_to_char_boundary, Fbuffer_swap_text)
10240 (Fset_buffer_multibyte, overlays_at, overlays_in)
10241 (overlay_touches_p, struct sortvec, record_overlay_string)
10242 (overlay_strings, recenter_overlay_lists)
10243 (adjust_overlays_for_insert, adjust_overlays_for_delete)
10244 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
10245 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
10246 (Foverlay_recenter, last_overlay_modification_hooks_used)
10247 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10248 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10249 (validate_region): Omit unnecessary test for b <= e,
10250 since that's guaranteed by the previous test.
10251 (adjust_overlays_for_delete): Avoid pos + length overflow.
10252 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10253 (report_overlay_modification):
10254 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10255 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10256 Omit pointer cast, which isn't needed anyway, and doesn't work
10257 after the EMACS_INT -> ptrdiff_t change.
10258 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10259 * buffer.h: Adjust decls to match defn changes elsewhere.
10260 (struct buffer_text, struct buffer):
10261 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10262 Use EMACS_INT, not int, where int might not be wide enough.
10263 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10264 not int, to avoid needless 32-bit limit on 64-bit hosts.
10265 (exec_byte_code): Use tighter memory-full test, one that checks
10266 for alloca overflow. Don't compute the address of the object just
10267 before an array, as that's not portable. Use EMACS_INT, not
10268 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10269 * callint.c (Fcall_interactively):
10270 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10271 * callproc.c (call_process_kill, Fcall_process):
10272 Don't assume pid_t fits into an Emacs fixnum.
10273 (call_process_cleanup, Fcall_process, child_setup):
10274 Don't assume pid_t fits into int.
10275 (call_process_cleanup, Fcall_process, delete_temp_file)
10276 (Fcall_process_region):
10277 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10278 (Fcall_process): Simplify handling of volatile integers.
10279 Use int, not EMACS_INT, where int will do.
10280 * casefiddle.c (casify_object, casify_region, operate_on_word)
10281 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10282 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10283 (casify_object): Avoid integer overflow when overallocating buffer.
10284 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10285 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10286 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10287 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10288 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10289 integers are now checked earlier. All uses replaced with XINT.
10291 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10292 For CCL_MapSingle, check that content and value are in int range.
10293 (ccl_driver, Fregister_code_conversion_map):
10294 Check that Vcode_version_map_vector is a vector.
10295 (resolve_symbol_ccl_program): Check that vector header is in range.
10296 Always copy the vector, so that we can check its contents reliably
10297 now rather than having to recheck each instruction as it's being
10298 executed. Check that vector words fit in 'int'.
10299 (ccl_get_compiled_code, Fregister_ccl_program)
10300 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10301 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10302 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10303 contents are in range.
10304 (Fccl_execute_on_string): Check that status is in range.
10305 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10306 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10307 Accept and return EMACS_INT, not int, because callers can pass values
10308 out of 'int' range.
10309 (c_string_width, strwidth, lisp_string_width, chars_in_text)
10310 (multibyte_chars_in_text, parse_str_as_multibyte)

10313 (string_escape_byte8, Fget_byte):
10314 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10315 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10316 avoid mishandling large integers.
10317 * character.h: Adjust decls to match defn changes elsewhere.
10318 * charset.c (load_charset_map_from_file, find_charsets_in_text)
10319 (Ffind_charset_region):
10320 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10321 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
10322 (load_charset_map_from_vector, Fdefine_charset_internal):
10323 Don't assume fixnum fits in int.
10324 (load_charset_map_from_vector, Fmap_charset_chars):
10325 Remove now-unnecessary CHECK_NATNUMs.
10326 (Fdefine_charset_internal): Check ranges here, more carefully.
10327 Don't rely on undefined behavior with signed left shift overflow.
10328 Don't assume unsigned int fits into fixnum, or that fixnum fits
10329 into unsigned int. Don't require max_code to be a valid fixnum;
10330 that's not true for gb10830 4-byte on a 32-bit host. Allow
10331 invalid_code to be a cons, for the same reason. Require code_offset
10332 to be a character. Avoid int overflow if max_char is close
10334 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10335 this is intended anyway and avoids some undefined behavior.
10336 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10337 INDEX_TO_CODE_POINT, as that's what it expects.
10338 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10339 * charset.h (DECODE_CHAR): Return int, not unsigned;
10340 this is what was intended anyway, and it avoids undefined behavior.
10341 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10342 integer-overflow issues.
10343 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10344 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10345 where the argument is EMACS_INT, and this behavior is not intended.
10346 * chartab.c (Fmake_char_table, Fset_char_table_range)
10347 (uniprop_get_decoder, uniprop_get_encoder):
10348 Don't assume fixnum fits in int.
10349 * cmds.c (move_point): New function, that does the gist of
10350 Fforward_char and Fbackward_char, but does so while checking
10351 for integer overflow more accurately.
10352 (Fforward_char, Fbackward_char): Use it.
10353 (Fforward_line, Fend_of_line, internal_self_insert)
10354 (internal_self_insert):
10355 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10356 Fix a FIXME, by checking for integer overflow when calculating
10357 target_clm and actual_clm.

10390 (consume_chars): Rewrite to not calculate an address outside buffer.
10391 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
10392 Don't access memory outside of the args array.
10393 (Fdefine_coding_system_internal): Check for charset-id overflow.
10394 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
10395 result of ENCODE_CHAR.
10396 * coding.h: Adjust decls to match defn changes elsewhere.
10397 (struct coding_system):

11090 2012-05-20 Ken Brown <kbrown@cornell.edu>
11092 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
11093 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11095 2012-05-19 Ken Brown <kbrown@cornell.edu>
11097 * xfns.c (x_in_use): Remove `static' qualifier.
11098 * xterm.h (x_in_use): Declare.
11099 * xgselect.c: Include xterm.h.
11100 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11101 and `display_arg' (bug#9754).
11103 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11105 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11107 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11108 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11110 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11112 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11114 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11115 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11117 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11118 reference to image_cache->refcount.
11119 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11121 2012-05-17 Juri Linkov <juri@jurta.org>
11123 * search.c (Fword_search_regexp, Fword_search_backward)
11124 (Fword_search_forward, Fword_search_backward_lax)
11125 (Fword_search_forward_lax): Move functions to isearch.el
11126 (bug#10145, bug#11381).
11128 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11130 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11132 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11134 * lread.c (init_obarray): Declare Qt and Qnil as special.
11136 2012-05-14 Glenn Morris <rgm@gnu.org>
11138 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11139 Put "libexec" before "bin", for the sake of init_callproc_1.
11141 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11143 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11145 * unexaix.c: Port to more-recent AIX compilers.
11146 (report_error, report_error_1, make_hdr, copy_sym)
11147 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11148 Make arguments const char *, not char *, to avoid violations of C
11149 standard and to fix some AIX warnings reported by Gilles Pion.
11151 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11153 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11154 already have overlays loaded.
11155 (handle_single_display_spec): Before returning without displaying
11156 fringe bitmap, synchronize the bidi iterator with the main display
11157 iterator, by calling iterate_out_of_display_property.
11158 (iterate_out_of_display_property): Detect buffer iteration by
11159 testing that it->string is a Lisp string.
11160 (get_next_display_element): When the current object is exhausted,
11161 and there's something on it->stack, call set_iterator_to_next to
11162 proceed with what's on the stack, instead of returning zero.
11163 (set_iterator_to_next): If called at the end of a Lisp string,
11164 proceed to consider_string_end without incrementing string
11165 position. Don't increment display vector index past the end of
11166 the display vector. (Bug#11417)
11167 (pos_visible_p): Don't report a position visible when move_it_to
11168 stopped at the last line of window, which happens to be scanned
11169 backwards by the bidi iteration. (Bug#11464)
11171 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11173 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11174 and right-margin display specs even if the spec is invalid or we
11175 are on a TTY, and thus unable to display on the fringes.
11176 That's because the text with the property will not be displayed anyway,
11177 so we need to signal to the caller that this is a "replacing"
11178 display spec. This fixes display when the spec is invalid or we
11181 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11183 * unexaix.c (make_hdr): Fix typo in prototype.
11184 This bug broke the build on AIX. Problem reported by Gilles Pion.
11186 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11188 * keyboard.c (kbd_buffer_get_event): Read special events also in
11189 batch mode. (Bug#11415)
11191 2012-05-12 Glenn Morris <rgm@gnu.org>
11193 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11195 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11197 * lisp.mk (lisp): Add newcomment.elc.
11199 2012-05-12 Glenn Morris <rgm@gnu.org>
11201 * Makefile.in (MKDIR_P): New, set by configure.
11202 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11204 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11206 Remove unused function hourglass_started.
11207 * dispextern.h (hourglass_started):
11208 * w32fns.c (hourglass_started):
11209 * xdisp.c (hourglass_started): Remove.
11211 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11213 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11214 Update dependencies.
11216 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11218 * xgselect.c (xg_select): Put maxfds+1 into a var.
11219 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11221 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11223 2012-05-10 Dave Abrahams <dave@boostpro.com>
11225 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11226 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11228 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11230 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11231 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11232 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11233 Initialize xd_registered_buses.
11235 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11237 Untag more efficiently if USE_LSB_TAG.
11238 This is based on a proposal by YAMAMOTO Mitsuharu in
11239 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11240 For an admittedly artificial (nth 8000 longlist) benchmark on
11241 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11242 Emacs's overall text size by 1%.
11243 * lisp.h (XUNTAG): New macro.
11244 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11245 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11246 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11247 * eval.c (Fautoload):
11248 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11249 * frame.h (XFRAME): Use XUNTAG.
11251 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11252 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11253 Remove unportable assumptions about print widths of types like
11255 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11256 intptr_t when converting between pointer and integer, to avoid GCC
11257 warnings about wrong width.
11259 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11261 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11262 stack for each reader_thread, instead of defaulting to 8MB
11263 determined by the linker. This avoids failures in creating
11264 subprocesses on Windows 7, see the discussion in this thread:
11265 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11267 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11269 Fix up display of the *Minibuf-0* buffer in the mini window.
11270 * keyboard.c (read_char): Don't clear the echo area if there's no
11272 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11273 contents of *Minibuf-0*) if there's no message displayed in its stead.
11275 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11277 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11280 2012-05-06 Chong Yidong <cyd@gnu.org>
11282 * lisp.mk (lisp): Update.
11284 2012-05-05 Jim Meyering <meyering@redhat.com>
11286 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11288 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11290 * data.c (PUT_ERROR): New macro.
11291 (syms_of_data): Use it. Add new error type `user-error'.
11292 * undo.c (user_error): New function.
11293 (Fprimitive_undo): Use it.
11294 * print.c (print_error_message): Adjust print style for `user-error'.
11295 * keyboard.c (user_error): New function.
11296 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11298 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11300 Do not limit current-time-string to years 1000..9999.
11301 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11302 (Fcurrent_time_string): Support any year that is supported by the
11303 underlying localtime representation. Don't use asctime, as it
11304 has undefined behavior for years outside the range -999..9999.
11306 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11308 Fix race conditions involving setenv, gmtime, localtime, asctime.
11309 Without this fix, interrupts could mess up code that uses these
11310 nonreentrant functions, since setting TZ invalidates existing
11311 tm_zone or tzname values, and since most of these functions return
11312 pointers to static storage.
11313 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11314 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11315 Grow the critical sections to include not just invoking
11316 localtime/gmtime, but also accessing these functions' results
11317 including their tm_zone values if any, and any related TZ setting.
11318 (format_time_string): Last arg is now struct tm *, not struct tm **,
11319 so that the struct tm is saved in the critical section.
11320 All callers changed. Simplify allocation of initial buffer, partly
11321 motivated by the fact that memory allocation needs to be outside
11322 the critical section.
11324 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11326 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11327 with RESET_INTERVAL.
11329 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11330 Remove duplicated buffer name initialization.
11332 2012-05-02 Jim Meyering <jim@meyering.net>
11334 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11336 * xfns.c (x_window): Use xstrdup (Bug#11375).
11338 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11340 * xdisp.c (pos_visible_p): If already at a newline from the
11341 display string before the 'while' loop, don't walk back the glyphs
11342 from it3.glyph_row. Solves assertion violation when the display
11343 string begins with a newline (egg.el). (Bug#11367)
11345 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11347 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11350 2012-05-01 Glenn Morris <rgm@gnu.org>
11352 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11353 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11354 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11355 All were removed before 23.1.
11357 * dispnew.c: Remove HAVE_LIBNCURSES test;
11358 it is always true on relevant platforms.
11360 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11361 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11363 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11365 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11367 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11368 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11371 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11373 Do not avoid creating empty evaporating overlays (Bug#9642).
11374 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11375 That is, do not delete an evaporating overlay if it becomes
11376 empty after its bounds are adjusted to fit within its buffer.
11377 This fix caused other problems, and I'm reverting it until we get
11378 to the bottom of them.
11380 2012-04-27 Chong Yidong <cyd@gnu.org>
11382 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11384 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11386 * xdisp.c (pos_visible_p): If the window start position is beyond
11387 ZV, start the display from buffer beginning. Prevents assertion
11388 violation in init_iterator when the minibuffer window is scrolled
11389 via the scroll bar.
11391 * window.c (window_scroll_pixel_based): Likewise.
11393 2012-04-27 Chong Yidong <cyd@gnu.org>
11395 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11397 2012-04-27 Glenn Morris <rgm@gnu.org>
11399 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11400 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11402 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11404 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11405 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11407 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11409 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11410 display element, check also the underlying string or buffer
11411 character. (Bug#11341)
11413 * w32menu.c: Include w32heap.h.
11414 (add_menu_item): If the call to AppendMenuW (via
11415 unicode_append_menu) fails, disable Unicode menus only if we are
11416 running on Windows 9X/Me.
11418 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11420 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11421 (xgetint): Add missing shift for LSB tags.
11423 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11425 * keyboard.c (read_char): Don't wipe echo area for select window
11426 events: These might get delayed via `mouse-autoselect-window'
11429 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11431 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11432 manipulation of :loaded-from data.
11434 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11436 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11437 now a cons (bug#11311).
11439 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11441 Do not create empty overlays with the evaporate property (Bug#9642).
11442 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11443 if it becomes empty after its bounds are adjusted to fit within
11444 its buffer. Without this fix, in a nonempty buffer (let ((o
11445 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11446 yields an empty overlay that has the evaporate property, which is
11447 not supposed to happen.
11449 Fix minor GTK3 problems found by static checking.
11450 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11451 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11452 (struct _EmacsFixedClass, emacs_fixed_get_type):
11453 Move decls here from emacsgtkfixed.h, since they needn't be public.
11454 (emacs_fixed_get_type): Now static.
11455 (emacs_fixed_class_init): Omit unused local.
11456 (emacs_fixed_child_type): Remove; unused.
11457 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11458 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11459 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11460 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11461 (EMACS_FIXED_GET_CLASS): Remove; unused.
11462 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11464 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11465 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11467 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11469 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11470 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11471 (__malloc_size_t, __malloc_ptrdiff_t):
11472 Remove. All uses removed, replaced by the definiens if needed,
11473 since we can assume C89 or better now.
11474 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

11480 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
11481 (special_realloc, _realloc_internal_nolock, _realloc_internal)
11482 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11483 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11484 Define using prototypes, not old style.
11485 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11486 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11487 (align): Don't assume that signed integer overflow wraps around.
11488 Omit unused local var.
11489 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
11490 (_free_internal_nolock, memalign, mallochook, reallochook):
11491 Omit no-longer-needed casts.
11492 (valloc): Use getpagesize, not __getpagesize.
11493 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11494 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11496 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11498 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11500 Move functions from C to Lisp. Make non-blocking method calls
11501 the default. Implement further D-Bus standard interfaces.
11503 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
11504 (QCdbus_request_name_allow_replacement)
11505 (QCdbus_request_name_replace_existing)

11519 (xd_signature, xd_append_arg): Allow float for integer types.
11520 (xd_get_connection_references): New function.
11521 (xd_get_connection_address): Rename from xd_initialize.
11522 Return cached address.
11523 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
11524 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp

11560 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
11562 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11564 * sysdep.c [__FreeBSD__]: Minor cleanups.
11565 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11566 Use Emacs indenting style more consistently. Avoid some casts.

11571 * sysdep.c (list_system_processes, system_process_attributes):
11572 Add implementation for FreeBSD (Bug#5243).

11578 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
11580 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
11581 It is never used otherwise.
11583 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
11585 * print.c (print_preprocess): Only check print_depth if print-circle
11587 (print_object): Check for cycles even when print-circle is nil and
11588 print-gensym is t, but only check print_depth if print-circle is nil.

11592 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11593 set the status to "failed" and ensure that sentinel is run.
11595 2012-04-20 Glenn Morris <rgm@gnu.org>
11597 * process.c (Fset_process_inherit_coding_system_flag)
11598 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

11626 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
11627 -Wunused-result, -Wunused-variable. This should go away once
11628 the Emacs and Gnulib regex code is merged.
11629 (xmalloc, xrealloc): Now static.
11631 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

11648 New extern decls, to avoid calling undeclared functions.
11649 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11650 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11651 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11652 (NEED_MEM_INSERT): New macro.
11653 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11654 Remove one incorrect comment and fix another.

11668 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
11669 Remove decls. This fixes an "It stinks!".
11671 * alloc.c (which_symbols): Fix alignment issue / type clash.
11673 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11675 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
11676 (struct Lisp_Misc_Any): Likewise.
11677 (struct Lisp_Free): Likewise.
11678 * alloc.c (union aligned_Lisp_Symbol): Define.

11690 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11691 * s/netbsd.h, s/sol2-6.h:
11692 Remove definition of GC_MARK_STACK, since the default now works.
11693 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

11695 no longer the default.
11696 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11698 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11700 * lread.c (lisp_file_lexically_bound_p):

11719 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11721 2012-04-11 Daniel Colascione <dancol@dancol.org>
11723 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11724 against is gone. It's better to use vfork now so that when Cygwin
11725 gains a new, working vfork, we use it automatically (bug#10398).
11727 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
11729 * window.c (save_window_save): Obey window-point-insertion-type.

11747 * w32.c (w32_delayed_load): Record the full path of the library
11748 being loaded (bug#10424).
11750 2012-04-09 Glenn Morris <rgm@gnu.org>
11752 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11753 not just in the obarray, before snarfing them. (Bug#11036)

11770 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11771 attempts per process (connection).
11773 2012-04-09 Chong Yidong <cyd@gnu.org>
11775 * eval.c (Fuser_variable_p, user_variable_p_eh)

11777 (Fdefvar): Caller changed.
11779 * callint.c (Finteractive, Fcall_interactively):
11780 * minibuf.c (Fread_variable): Callers changed.
11782 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11784 * xdisp.c (set_cursor_from_row): If the display string appears in
11785 the buffer at position that is closer to point than the position
11786 after the display string, display the cursor on the first glyph of
11787 the display string. Fixes cursor display when a 'display' text
11788 property immediately follows invisible text. (Bug#11094)
11790 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11792 composite.c: use 'double' consistently
11793 * composite.c (get_composition_id): Use 'double' consistently
11794 instead of converting 'float' to 'double' and vice versa; this is
11795 easier to understand and avoids a GCC warning.
11797 2012-04-09 Glenn Morris <rgm@gnu.org>
11799 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11800 preparation for dumping it with emacs. (Bug#4789)

11822 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11823 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11824 objects, as mark_maybe_pointer will catch them otherwise.

11842 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11843 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11844 [!WINDOWSNT]: New macros.
11845 (init_libxml2_functions, libxml2_loaded_p): New functions.
11846 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11847 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11848 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11849 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11851 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11852 Call init_libxml2_functions before calling libxml2 functions.
11853 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11855 * emacs.c: Don't include libxml/parser.h.

11861 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11863 * indent.c (Fvertical_motion): If there is a display string at
11864 point, use it.vpos to compute how many lines to backtrack after
11865 move_it_to point. (Bug#11133)
11867 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11869 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11870 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11871 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11872 macros related to unification of CJK characters. For the details,
11873 see the discussion following the message here:
11874 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11876 2012-04-04 Chong Yidong <cyd@gnu.org>
11878 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11880 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11882 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

11890 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11892 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11893 position we get to after a call to move_it_to fails the
11894 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11895 only if we wind up in a string from display property. (Bug#11063)
11897 * window.c (Fdelete_other_windows_internal): Invalidate the row
11898 and column information about mouse highlight, so that redisplay
11899 restores it after reallocating the glyph matrices. (Bug#7464)
11901 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11902 string comes from a `display' text property, use the buffer
11903 position of that property as if we actually saw that position in
11905 (move_it_by_lines): Remove the assertion that
11906 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11907 violated when there's a before-string at the beginning of a line.
11910 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11912 * xdisp.c (append_space_for_newline): If the default face was

11915 extending the face to the end of the line.
11916 (display_line): Call extend_face_to_end_of_line when the default
11917 face was remapped. (Bug#11068)
11919 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11921 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

11939 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11940 (command_loop_1): Use it; inhibit selection update for

11945 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11947 2012-03-25 Kenichi Handa <handa@m17n.org>
11949 * dispextern.h (struct glyph): Change the bit length of
11950 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11952 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11954 * s/ms-w32.h (tzname): Include time.h before redirecting to

11965 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11967 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11968 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11969 when fetching a multibyte character consumes more bytes than
11970 CHAR_BYTES returns, due to unification of CJK characters in
11971 string_char. (Bug#11073)
11973 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11975 * process.c (wait_reading_process_output): Handle pty disconnect
11976 by refraining from sending oneself a SIGCHLD (bug#10933).

12005 it fit in a valid range (Bug#11003).
12007 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12009 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12010 that is not from display property, accept the row as a "cursor
12011 row" if one of the string's character has a non-nil `cursor'
12012 property. Fixes cursor positioning when there are newlines in
12013 overlay strings, e.g. in icomplete.el. (Bug#11035)
12015 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
12017 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

12049 2012-03-03 Glenn Morris <rgm@gnu.org>
12051 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12053 2012-03-02 Eli Zaretskii <eliz@gnu.org>

12066 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12068 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12069 push_it before setting up the iterator for the first overlay
12070 string, even if we have an empty string loaded.
12071 (next_overlay_string): If there's an empty string on the iterator
12072 stack, pop the stack. (Bug#10903)
12074 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12076 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12077 Suggested by Stefan Monnier in
12078 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12079 * alloc.c (widen_to_Lisp_Object): New static function.
12080 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12081 and widening them to Lisp_Objects. This would work even if
12082 USE_LSB_TAG is defined and wide integers are used, which might
12083 happen in a future version of Emacs.
12085 2012-02-25 Chong Yidong <cyd@gnu.org>
12087 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

12092 before saving to clipboard manager.
12094 2012-02-24 Chong Yidong <cyd@gnu.org>
12096 * keyboard.c (process_special_events): Handle all X selection
12097 requests in kbd_buffer, not just the next one (Bug#8869).
12099 2012-02-23 Chong Yidong <cyd@gnu.org>
12101 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12102 call when setting menu-bar-lines and tool-bar-lines parameters.
12103 (unwind_create_frame_1): New helper function.

12124 when computing $valmask.
12126 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12127 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12128 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12129 It's useless in that case, and it can cause problems on hosts
12130 that allocate halves of EMACS_INT values separately.
12131 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12132 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12133 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12134 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12135 it avoids undefined behavior on hosts where shifting right by more
12136 than the word width has undefined behavior.
12138 2012-02-19 Chong Yidong <cyd@gnu.org>
12140 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12141 (Funhandled_file_name_directory, Ffile_name_as_directory)
12142 (Fdirectory_file_name, Fexpand_file_name)
12143 (Fsubstitute_in_file_name): Protect against invalid file handler
12144 return values (Bug#10845).

12158 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12160 2012-02-15 Chong Yidong <cyd@gnu.org>
12162 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12163 marked as special. Also, starting docstrings with * is obsolete.

12178 2012-02-12 Chong Yidong <cyd@gnu.org>
12180 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12181 as that creates a dangerous corner case.
12183 * window.c (Fdelete_window_internal): Invalidate the mouse
12184 highlight (Bug#9904).
12186 2012-02-12 Glenn Morris <rgm@gnu.org>

12191 * nsselect.m (Fx_own_selection_internal)
12192 (Fx_disown_selection_internal, Fx_selection_exists_p)
12193 (Fx_selection_owner_p, Fx_get_selection_internal):
12194 Sync docs and argument specs with the xselect.c versions.
12196 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

12216 2012-02-07 Chong Yidong <cyd@gnu.org>
12218 * buffer.c (Fbuffer_local_variables)
12219 (buffer_lisp_local_variables): Handle unbound vars correctly;
12220 don't let Qunbound leak into Lisp.
12222 2012-02-07 Glenn Morris <rgm@gnu.org>
12224 * image.c (Fimagemagick_types): Doc fix.
12226 * image.c (imagemagick-render-type): Change it from a lisp object
12227 to an integer. Move the doc here from the lisp manual.

12244 2012-02-04 Eli Zaretskii <eliz@gnu.org>
12246 * w32.c (get_emacs_configuration_options):
12247 Include --enable-checking, if specified, in the return value.

12261 Handle overflow when computing char display width (Bug#9496).
12262 * character.c (char_width): Return EMACS_INT, not int.
12263 (char_width, c_string_width): Check for overflow when
12264 computing the width; this is possible now that individual
12265 characters can have unbounded width. Problem introduced
12266 by merge from Emacs 23 on 2012-01-19.

12290 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
12292 (x_produce_glyphs): If the component of a composition is a null
12293 string, set it->pixel_width to 1 to avoid zero-width glyph.

12297 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
12298 first 2 arguments are identical. This makes inserting large
12299 output from a subprocess an order of magnitude faster on
12300 MS-Windows, where all sbrk'ed memory is always contiguous.
12302 2012-01-31 Glenn Morris <rgm@gnu.org>

12385 2012-01-11 Glenn Morris <rgm@gnu.org>
12387 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
12388 from load-path also when installation-directory is nil. (Bug#10208)

12395 Update template values to be closer to their typical values these days.
12397 2012-01-09 Eli Zaretskii <eliz@gnu.org>
12399 * xdisp.c (rows_from_pos_range): Accept additional argument
12400 DISP_STRING, and accept any glyph in a row whose object is that
12401 string as eligible for mouse highlight. Fixes mouse highlight of
12402 display strings from overlays. (Bug#10464)
12404 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
12406 emacs: fix an auto-save permissions race condition (Bug#10400)

12408 (Fmake_directory_internal): Use it.
12409 (do_auto_save_make_dir): Set it, instead of invoking chmod after

12413 (Fdo_auto_save): Catch all errors, not just file errors, so
12414 that the var is always cleared.

12753 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12754 verifies glyph row's hash code--we have just reallocated the

12916 Otherwise, valgrind does not work on some platforms.
12917 Problem reported by Andreas Schwab in
12918 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
12919 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12920 is set, removing the need for VIRT_ADDRESS_VARIES.
12921 (PURE_P): Use a more-efficient implementation that needs just one
12922 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
12923 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
12924 to 4 (xorl, subq, cmpq, setbe).
12925 * alloc.c (pure): Always extern now, since that's the
12926 VIRT_ADDR_VARIES behavior.
12927 (PURE_POINTER_P): Use a single comparison, not two, for
12928 consistency with the new puresize.h.
12929 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

13394 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13396 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
13397 <oslsachem@gmail.com> for helping to debug this.
13399 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
13400 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
13401 (g_b_init_get_glyph_outline_w): New static variables.
13402 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
13403 (GetGlyphOutlineW_Proc): New typedefs.
13404 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
13405 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
13407 (w32font_open_internal, compute_metrics):
13408 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13409 instead of calling the "wide" APIs directly.
13411 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13413 * w32.h (syms_of_w32font): Add prototype.
13415 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13417 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
13418 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
13419 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
13420 (Fmove_to_window_line): Doc fix.
13422 2011-10-27 Chong Yidong <cyd@gnu.org>
13424 * process.c (make_process): Set gnutls_state to NULL.
13426 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13427 non-NULL, regardless of GNUTLS_INITSTAGE.
13428 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13429 an error. Set process slots as soon as we allocate them.
13431 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13433 2011-10-27 Chong Yidong <cyd@gnu.org>
13435 * gnutls.c (emacs_gnutls_deinit): New function.
13436 Deallocate credentials structures as well as calling gnutls_deinit.
13437 (Fgnutls_deinit, Fgnutls_boot): Use it.
13439 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13440 (deactivate_process): Call emacs_gnutls_deinit.
13442 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13444 * image.c (x_create_x_image_and_pixmap):
13445 * w32.c (sys_rename, w32_delayed_load):
13446 * w32font.c (fill_in_logfont):
13447 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13449 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13451 * w32fns.c (w32_default_color_map): New function,
13452 extracted from Fw32_default_color_map.
13453 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13455 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13457 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13459 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13461 * keyboard.c (test_undefined): New function (bug#9751).
13462 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13464 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13466 * sysdep.c (init_sys_modes): Fix the check for the controlling
13467 terminal (Bug#6649).
13469 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13471 * dispextern.h (struct bidi_it): New member next_en_type.
13473 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13474 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13475 current character, check also for next_en_type being WEAK_EN.
13476 (bidi_resolve_weak): Don't enter the expensive loop if the current
13477 position is before next_en_pos. Record the bidi type of the first
13478 non-ET, non-BN character we find, in addition to its position.
13479 (bidi_level_of_next_char): Invalidate next_en_type when
13480 next_en_pos is over-stepped.
13482 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13484 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13485 * editfns.c: Rewrite current-time-zone so that it invokes
13486 the equivalent of (format-time-string "%Z") to get the time zone name.
13487 This fixes a bug when the time zone name contains characters that
13488 need converting from the system time locale to Emacs internal format.
13489 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13490 that patch fixed format-time-string to do the conversion, but
13491 I forgot to fix current-time-zone.
13492 (format_time_string): New function, containing most of
13493 what Fformat_time_string used to contain.
13494 (Fformat_time_string): Rewrite in terms of format_time_string.
13495 This doesn't change this function's behavior.
13496 (current-time-zone): Rewrite to use format_time_string.
13497 This fixes the bug reported by Michael Schierl in
13498 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13499 Jason Rumney's 2007-06-07 change worked around this bug, but
13501 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13503 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13505 * xdisp.c (start_display): If the character at POS is displayed
13506 via a display vector, reset IT->current.dpvec_index to zero.
13507 (try_window_reusing_current_matrix): If a line ends in a display
13508 vector or the next line starts in a display vector, continue
13509 redrawing the window even though the character position of
13510 start_row was reached.
13513 2011-10-18 Chong Yidong <cyd@gnu.org>
13515 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13516 with nobreak-char-display too.
13518 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13520 Fix part 3 of bug#9771.
13521 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13522 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13523 non-neutral characters if the current character is a paragraph
13524 separator (a.k.a. Newline). This avoids running the same
13525 expensive loop twice, once when we consume the preceding newline
13526 and the other time when the line actually needs to be displayed.
13527 Avoid the loop when we see neutrals on the base embedding level
13528 following a character whose directionality is the same as the
13529 paragraph's. This avoids running the expensive loop when a line
13530 ends in a long sequence of neutrals, like control characters.
13531 Add assertion against STRONG_AL type. Slightly rearrange code
13532 that determines the type of a neutral given the first non-neutral
13534 (bidi_level_of_next_char): Set next_en_pos to zero when
13535 invalidating its info.
13537 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13539 * xdisp.c (push_display_prop): Determine whether to record string
13540 or buffer position by IT->string, not by IT->method. Allow
13541 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13542 (move_it_vertically_backward): Don't look for character position
13543 immediately after the newline when in a continuation line.
13546 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13548 * window.c (coordinates_in_window): Rewrite and delabelize
13549 vertical border check. (Bug#5357) (Bug#9618)
13551 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13553 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13554 errors in XSetWindowBorder (bug#9310).
13556 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13558 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13559 avoid crash when xmalloc overrun checking is enabled.
13561 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13563 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13564 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13565 cursor motion with <left> and <right> arrow keys.
13567 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13568 some callers set that themselves.
13570 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13572 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13573 display string and the previous row comes from the same string and
13574 is empty. (Bug#9739) (Bug#9738)
13576 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13578 * doc.c (get_doc_string): Encode file name (bug#9735).
13580 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13582 * bidi.c (bidi_level_of_next_char):
13583 * xdisp.c (get_visually_first_element): Remove old incorrect
13584 comments regarding the Unicode Line Separator character.
13586 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13588 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13590 * alloc.c (Fgc_status): Do not access beyond zombies array
13591 boundary if nzombies > MAX_ZOMBIES.
13592 * alloc.c (dump_zombies): Add missing format specifier.
13594 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13596 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13597 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13599 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13600 Some packages use them to denote characters with modifiers.
13602 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13604 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13605 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13606 matching a pp-number. Rename parameter var to var1.
13608 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13610 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13612 2011-10-08 Glenn Morris <rgm@gnu.org>
13614 * callint.c (Fcall_interactively): Give a more explicit error for the
13615 'c' case with a non-character input. (Bug#8479)
13617 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13619 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13621 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13622 lines that are hscrolled on the left.
13624 * dispnew.c (buffer_posn_from_coords): Account for a possible
13625 presence of header-line. (Bug#4426)
13627 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13629 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13630 Don't advertise functionality which we discourage or doesn't work.
13632 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13634 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13635 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13636 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13637 this makes Emacs dump core during garbage collection on rare
13638 occasions. sizeof is obviously inferior to offsetof here, so
13639 stick with offsetof.
13640 (GC_POINTER_ALIGNMENT): New macro.
13641 (mark_memory): Omit 3rd (offset) arg; caller changed.
13642 Don't assume EMACS_INT alignment is the same as pointer alignment.
13644 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13646 * keyboard.c (read_key_sequence_remapped): New var.
13647 (read_key_sequence): Compute remapping in the right buffer.
13648 (command_loop_1): Use read_key_sequence's remapping directly.
13650 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13652 * dired.c (file_name_completion): Don't expand file name.
13653 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13654 before checking file name handler.
13656 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13657 they've been requested explicitly (bug#9591).
13659 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13661 * keymap.c (Fsingle_key_description): Use make_specified_string
13662 instead of build_string to build string from push_key_description.
13665 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13667 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13668 This fixes a Y2038 bug on 64-bit hosts.
13669 * buffer.c (reset_buffer):
13670 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13671 (Fclear_buffer_auto_save_failure):
13672 Use 0, not -1, to represent an unset failure time, since time_t
13673 might not be signed.
13675 Remove dependency on glibc malloc internals.
13676 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13677 Move back here from lisp.h, but with their new implementations.
13678 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13679 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13680 * charset.c (charset_table_init): New static var.
13681 (syms_of_charset): Use it instead of xmalloc. This removes a
13682 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13683 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13684 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13685 Move back to alloc.c.
13686 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13687 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13689 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13691 * nsterm.m (windowDidResize): Call x_set_window_size only when
13692 ns_in_resize is true. Otherwise set pixelwidth/height and
13693 call change_frame_size (Bug#9628).
13695 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13697 Port --enable-checking=all to Fedora 14 x86-64.
13698 * charset.c (syms_of_charset): Also account for glibc malloc's
13699 internal overhead when calculating the initial malloc maximum.
13701 Port --enable-checking=all to Fedora 14 x86.
13702 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13704 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13705 (overrun_check_realloc, overrun_check_free):
13706 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13707 That way, xmalloc returns a properly-aligned pointer even if
13708 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13709 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13710 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13711 into account when calculating the initial malloc maximum.
13712 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13713 Move here from alloc.c, so that charset.c can use it too.
13714 Properly align; the old code wasn't right for common 32-bit hosts
13715 when configured with --enable-checking=all.
13716 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13717 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13719 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13721 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13724 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13726 * xdisp.c (compute_display_string_end): If there's no display
13727 string at CHARPOS, return -1.
13729 * bidi.c (bidi_fetch_char): When compute_display_string_end
13730 returns a negative value, treat the character as a normal
13731 character not covered by a display string. (Bug#9624)
13733 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13735 * lread.c (Fread_from_string): Fix typo in docstring.
13737 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13739 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13740 newline, reseat the iterator instead of bidi-iterating there one
13741 character at a time. (Bug#9610)
13742 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13743 TO_CHARPOS if the bidi iterator is at base embedding level.
13745 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13747 * lread.c (readevalloop): Use correct code for NBSP.
13748 (read1): Likewise. (Bug#9608)
13750 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13752 * dbusbind.c (Fdbus_register_signal): When service is not
13753 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13755 2011-09-25 Glenn Morris <rgm@gnu.org>
13757 * buffer.c (truncate-lines): Doc fix.
13759 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13761 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13762 (Fset_window_next_buffers): Doc fix.
13764 2011-09-24 Glenn Morris <rgm@gnu.org>
13766 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13768 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13770 Fix minor problems found by static checking.
13771 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13772 * indent.c (Fvertical_motion): Fix == vs = typo.
13774 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13776 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13777 Default value is now t. Doc fix.
13779 * indent.c (Fvertical_motion): Compute and apply the overshoot
13780 logic when moving up, not only when moving down. Fix the
13781 confusing name and values of the it_overshoot_expected variable;
13782 logic changes accordingly. (Bug#9254) (Bug#9549)
13784 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13785 CHARPOS is covered by a display string which includes newlines.
13786 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13787 is covered by a display string with embedded newlines.
13789 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13791 * dbusbind.c (Fdbus_register_signal): Add match rule to
13792 Vdbus_registered_objects_table. (Bug#9581)
13793 (Fdbus_register_method, Vdbus_registered_objects_table):
13796 2011-09-24 Jim Meyering <meyering@redhat.com>
13798 do not ignore write error for any output size
13799 The previous change was incomplete.
13800 While it makes emacs --batch detect the vast majority of stdout
13801 write failures, errors were still ignored whenever the output size is
13802 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13803 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13804 && echo FAIL: ignored write error
13805 FAIL: ignored write error
13806 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13807 && echo FAIL: ignored write error
13808 FAIL: ignored write error
13809 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13811 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13813 * emacs.c (Fkill_emacs): In noninteractive mode exit
13814 non-successfully if a write error occurred on stdout. (Bug#9574)
13816 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13818 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13821 * dispextern.h (struct it): Update the comment documenting what
13824 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13826 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13827 a display string, extend search for cursor position to end of row.
13828 (find_row_edges): If the row ends in a newline from a display
13829 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13830 Handle the case of a display string with multiple newlines.
13831 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13832 non-empty line. Fixes confusing cursor motion with arrow keys at
13833 the beginning of a line that starts with whitespace.
13835 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>

13840 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13842 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13843 boolean (Bug#9154).
13845 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13847 * xdisp.c (display_line): Record maximum and minimum buffer
13848 positions even if no glyphs were produced (e.g., by a zero-width
13849 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13850 buffer positions that will be removed from the glyph row because
13852 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13853 column is beyond frame width: don't subtract 1 "pixel" when
13854 computing width of the stretch.
13855 (reseat_at_next_visible_line_start): Undo the change made on
13856 2011-09-17 that saved paragraph information and restored it after
13857 the call to `reseat'. (Bug#9545)
13859 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13861 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13862 and turn window cursor on if cleared (Bug#9415).
13864 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13866 * search.c (boyer_moore): Take unibyte characters from pattern
13867 literally. (Bug#9458)
13869 2011-09-18 Eli Zaretskii <eliz@gnu.org>

13873 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13875 Fix minor problem found by static checking.
13876 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13877 initialized, to pacify gcc -Wuninitialized.
13879 * fileio.c: Report proper errno when syscall falls.
13880 (Finsert_file_contents): Save and restore errno,
13881 so that report_file_error outputs the correct diagnostic.
13882 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13884 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13886 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13888 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13890 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13891 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13893 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13895 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13896 about the current paragraph and restore it after the call to reseat.
13898 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13899 (bidi_find_paragraph_start): Search back for paragraph beginning
13900 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13901 (bidi_move_to_visually_next): Only trigger paragraph-related
13902 computations when the last character is a newline or at EOB, not
13903 just any NEUTRAL_B. (Bug#9470)
13905 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13906 truncated lines if point is covered by a display string. (Bug#9524)
13908 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13910 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13911 (cons_to_x_long): New function.
13912 (lisp_data_to_selection_data): Use it. Correct the test for
13913 short-versus-long data; it was negated. Break out of vector
13914 loop, for efficiency, when a long datum is discovered.
13916 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13918 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13920 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13922 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13923 GCC PR/17406) by declaring this function with external scope.
13925 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13927 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13928 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13930 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13932 * editfns.c (Fformat): Correctly handle text properties on "%%".

13938 * term.c (encode_terminal_code):
13939 * composite.c (composition_update_it, get_composition_id):
13940 * xdisp.c (get_next_display_element)
13941 (fill_composite_glyph_string): Add comments about special meaning
13942 of TAB characters in a composition.
13944 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13946 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13947 This occurs when processing a multibyte format.
13948 Problem reported by Wolfgang Jenker.
13950 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13952 * xdisp.c (try_cursor_movement): Only check for exact match if
13953 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13955 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13957 Remove unused external symbols.
13958 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13959 * xdisp.c (calc_pixel_width_or_height): Now static.
13960 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13961 * indent.c (check_display_width):
13962 * w32term.c: Fix comment to match code.
13963 * xterm.c, xterm.h (x_catching_errors): Remove.
13965 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13967 * xselect.c: Use signed conversions more consistently (Bug#9498).
13968 (selection_data_to_lisp_data): Assume incoming selection data are
13969 signed integers, not unsigned. This is to be consistent with
13970 outgoing selection data, which was modified to use signed integers
13971 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13972 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13973 expects long, not unsigned long.
13975 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13977 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13978 computation of loop end. Reported by Johan Bockgård
13981 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13983 * frame.c (Fother_visible_frames_p): Function deleted.
13985 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13987 * indent.c (compute_motion): Process display vector front to back
13988 rather than the other way around. (Bug#2496)
13990 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13992 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13994 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13996 * minibuf.c (Fread_from_minibuffer): Doc fix.
13998 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14000 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14001 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14003 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14005 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14006 value for non-existent files.
14008 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14010 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14011 set its "size" to -1. This will set the modtime_size field of
14012 the corresponding buffer to -1, which is what
14013 verify-visited-file-modtime expects for files that do not exist.
14016 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14018 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14020 * lisp.h: ... from here. push_key_description is no longer
14021 defined in keyboard.c, so its declaration should not be in
14022 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14023 logically belongs with push_key_description.
14025 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14027 * buffer.h: Include <sys/types.h> instead of <time.h>.
14028 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14029 Problem reported by Herbert J. Skuhra.
14031 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14033 * xml.c (parse_region): Make the parsing work for
14034 non-comment-starting XML files again (bug#9144).
14036 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14038 * image.c (gif_load): Fix calculation of bottom and right corner.
14041 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14043 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14044 redisplay in small windows.
14046 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14048 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14050 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14052 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14053 Operate on live windows only.
14055 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14057 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14059 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14061 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14062 only under bidi iteration.
14064 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14066 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14068 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14070 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14071 Without this fix, the command to link temacs failed due to an
14072 undefined symbol __builtin_isnan. This is because
14073 /usr/include/iso/math_c99.h #defines isnan(x) to
14074 __builtin_isnan(x), but the bundled gcc, which identifies itself
14075 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14077 * floatfns.c (isnan): #undef, and then #define to a clone of
14079 (Fisnan): Always define, since it's always available now.
14080 (syms_of_floatfns): Always define isnan at the Lisp level.
14082 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14084 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14086 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14088 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14089 The previous code assumed that file offsets (off_t values) fit in
14090 EMACS_INT variables, which is not true on typical 32-bit hosts.
14091 The code messed up by falsely reporting buffer overflow in cases
14092 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14093 when "big" contains more than 2**29 bytes, even though this
14094 inserts just one byte and does not overflow the buffer.
14095 (Finsert_file_contents): Store file offsets as off_t
14096 values, not as EMACS_INT values. Check for overflow when
14097 converting between EMACS_INT and off_t. When checking for
14098 buffer overflow or for overlap, take the offsets into account.
14099 Don't use EMACS_INT for small values where int suffices.
14100 When checking for overlap, fix a typo: ZV was used where
14101 ZV_BYTE was intended.
14102 (Fwrite_region): Don't assume off_t fits into 'long'.
14103 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14105 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14107 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14109 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14111 sprintf-related integer and memory overflow issues (Bug#9412).
14113 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14114 (esprintf, exprintf, evxprintf): New functions.
14115 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14116 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14117 (modify_event_symbol): Do not assume that the length of
14118 name_alist_or_stem is safe to alloca and fits in int.
14119 (Fexecute_extended_command): Likewise for function name and binding.
14120 (Frecursion_depth): Wrap around reliably on integer overflow.
14121 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14122 since some callers pass EMACS_INT values.
14123 (Fsingle_key_description): Don't crash if symbol name contains more
14124 than MAX_ALLOCA bytes.
14125 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14126 (get_minibuffer): Arg is now EMACS_INT, not int.
14127 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14128 (esprintf, exprintf, evxprintf): New decls.
14129 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14131 * dbusbind.c (signature_cat): New function.
14132 (xd_signature, Fdbus_register_signal):
14133 Do not overrun buffer; instead, report string overflow.
14135 * dispnew.c (add_window_display_history): Don't overrun buffer.
14136 Truncate instead; this is OK since it's just a log.
14138 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14139 even if the time zone offset is outlandishly large.
14140 Don't mishandle offset == INT_MIN.
14142 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14143 when creating daemon; the previous buffer-overflow check was incorrect.
14145 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14146 which has the guts of the old verror function.
14148 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14149 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14151 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14152 (font_unparse_xlfd): Don't blindly alloca long strings.
14153 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14154 fits in int, when using sprintf. Use single snprintf to count
14155 length of string rather than counting it via multiple sprintfs;
14156 that's simpler and more reliable.
14157 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14158 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14159 sprintf, in case result does not fit in int.
14161 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14162 (fontset_from_font): Print it.
14164 * frame.c (tty_frame_count): Now printmax_t, not int.
14165 (make_terminal_frame, set_term_frame_name): Print it.
14166 (x_report_frame_params): In X, window IDs are unsigned long,
14167 not signed long, so print them as unsigned.
14168 (validate_x_resource_name): Check for implausibly long names,
14169 and don't assume name length fits in 'int'.
14170 (x_get_resource_string): Don't blindly alloca invocation name;
14171 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14174 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14175 (xg_check_special_colors, xg_set_geometry):
14176 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14178 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14179 Use esprintf, not sprintf, in case result does not fit in int.
14181 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14182 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14183 it as a large positive number.
14184 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14185 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14187 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14188 in case result does not fit in int.
14190 * print.c (float_to_string): Detect width overflow more reliably.
14191 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14192 buffer overrun. Don't assume list length fits in 'int'. Treat
14193 print length of 0 as 0, not as infinity; to be consistent with other
14194 uses of print length in this function. Don't overflow print length
14195 index. Don't assume hash table size fits in 'long', or that
14196 vectorlike size fits in 'unsigned long'.
14198 * process.c (make_process): Use printmax_t, not int, to format
14199 process-name gensyms.
14201 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14203 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14204 to avoid potential buffer overrun.
14206 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14207 if X resource line is longer than 512 bytes.
14209 * xfns.c (x_window): Make sprintf buffer a bit bigger
14210 to avoid potential buffer overrun.
14212 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14214 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14216 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14218 Integer overflow fixes for scrolling, etc.
14219 Without these, Emacs silently mishandles large integers sometimes.
14220 For example, "C-u 4294967297 M-x recenter" was treated as if
14221 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14223 * xdisp.c (try_window_id): Check Emacs fixnum range before
14224 converting to 'int'.
14226 * window.c (window_scroll_line_based, Frecenter):
14227 Check that an Emacs fixnum is in range before assigning it to 'int'.
14228 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14229 values converted from Emacs fixnums.
14230 (Frecenter): Don't wrap around a line count if it is out of 'int'
14231 range; instead, treat it as an extreme value.
14232 (Fset_window_configuration, compare_window_configurations):
14233 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14235 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14236 that can exceed INT_MAX. Check that EMACS_INT value is in range
14237 before assigning it to the (possibly-narrower) index.
14238 (match_limit): Don't assume that a fixnum can fit in 'int'.
14240 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14243 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14244 (Fvertical_motion): Don't wrap around LINES values that don't fit
14245 in 'int'. Instead, treat them as extreme values. This is good
14246 enough for windows, which can't have more than INT_MAX lines anyway.
14248 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14250 * Require libxml/parser.h to avoid compilation warning.
14252 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14254 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14255 since this reportedly can destroy thread storage.
14257 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14259 * syntax.c (find_defun_start): Update all cache variables if
14260 exiting early (Bug#9401).
14262 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14264 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14266 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14267 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14268 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14270 * term.c (tty_append_glyph): New function.
14271 (produce_stretch_glyph): Static function and its prototype deleted.
14273 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14276 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14278 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14279 when checking :margin (Bug#9390).
14280 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14281 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14282 so that the name doesn't mislead. All uses changed.
14284 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14286 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14289 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14291 * xdisp.c (move_it_to): Don't bail out early when reaching
14292 position beyond to_charpos, if we are scanning backwards.
14293 (move_it_vertically_backward): When DY == 0, make sure we get to
14294 the first character in the line after the newline.
14296 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14298 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14299 (ccl_driver): Do not generate an out-of-range pointer.
14300 (Fccl_execute_on_string): Remove unnecessary check for
14301 integer overflow, noted by Stefan Monnier in
14302 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14303 Remove a FIXME that didn't need fixing.
14304 Simplify the newly-introduced buffer reallocation code.
14306 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14308 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14310 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14312 Integer and memory overflow issues (Bug#9196).
14314 * doc.c (get_doc_string): Rework so that
14315 get_doc_string_buffer_size is the actual buffer size, rather than
14316 being 1 less than the actual buffer size; this makes xpalloc more
14319 * image.c (x_allocate_bitmap_record, cache_image):
14320 * xselect.c (Fx_register_dnd_atom):
14321 Simplify previous changes by using xpalloc.
14323 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14324 since either will do and ptrdiff_t is convenient with xpalloc.
14326 * charset.c (charset_table_size)
14327 (struct charset_sort_data.priority): Now ptrdiff_t.
14328 (charset_compare): Don't overflow if priorities differ greatly.
14329 (Fsort_charsets): Don't assume list length fits in int.
14330 Check for size-calculation overflow when allocating sort data.
14331 (syms_of_charset): Allocate an initial charset table that is
14332 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14334 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14336 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14337 The actual value is always <= INT_MAX, and leaving it unsigned made
14338 overflow checking harder.
14340 * dispextern.h (struct glyph_matrix.rows_allocated)
14341 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14342 with xpalloc. The values are still always <= INT_MAX.
14344 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14346 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14347 (SAFE_NALLOCA): New macro.
14349 * region-cache.c (struct boundary.pos, find_cache_boundary)
14350 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14351 (set_cache_region, invalidate_region_cache)
14352 (revalidate_region_cache, know_region_cache, region_cache_forward)
14353 (region_cache_backward, pp_cache):
14354 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14355 so that ptrdiff_t * can be passed to xpalloc.
14356 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14357 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14358 (pp_cache): Don't assume cache_len fits in int.
14359 * region-cache.h: Adjust extern decls to match.
14361 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14362 EMACS_INT, since either will do, for xpalloc.
14364 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14365 (xnmalloc, xnrealloc, xpalloc): New functions.
14367 * bidi.c (bidi_shelve_header_size): New constant.
14368 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14369 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14371 * bidi.c (bidi_cache_shrink):
14372 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14374 Don't update size of array until after memory allocation succeeds,
14375 because xmalloc/xrealloc may not return.
14376 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14377 now that we have proper integer overflow checking.
14378 (record_overlay_string, overlay_strings): Catch overflows when
14379 calculating size of overlay_str_buf.
14381 * callproc.c (Fcall_process): Check for size overflow when
14382 calculating size of args2.
14383 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14384 Normally we prefer signed values, but sticking with ptrdiff_t would
14385 require adding more-complicated checks.
14387 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14388 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14389 Redo buffer-overflow calculations to avoid integer overflow.
14390 Add a FIXME comment where memory seems to be over-allocated.
14392 * character.c (Fstring): Check for size-calculation overflow.
14394 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14395 unnecessary integer overflow. Check for size overflow.
14396 (encode_coding_object): Don't update size until xmalloc succeeds.
14398 * composite.c (get_composition_id): Check for overflow in glyph
14399 length calculations.
14401 Integer and memory overflow fixes for display code.
14402 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14403 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14404 (scrolling_window): Check for overflow in size calculations.

14409 (scrolling_window): Avoid overflow in size calculations.
14410 Don't update size until allocation succeeds.
14411 * fns.c (concat): Check for overflow in size calculations.
14412 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
14413 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

14416 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14417 (get_doc_string): Check for size calculation overflow.
14418 Don't update size until allocation succeeds.
14419 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14420 EMACS_INT, where ptrdiff_t will do.
14421 (Fsubstitute_command_keys): Check for string overflow.
14423 * editfns.c (set_time_zone_rule): Don't assume environment length
14425 (message_length): Now ptrdiff_t, not int.
14426 (Fmessage_box): Don't update size until allocation succeeds.
14427 Don't assume message length fits in int.
14428 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14430 * emacs.c (main): Do not reallocate argv, since there is a null at
14431 the end that can be overwritten, and this way there's no need to
14432 worry about size-calculation overflow.
14433 (sort_args): Check for size-calculation overflow.
14435 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14437 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
14439 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
14440 (x_set_scroll_bar_width, x_figure_window_size):
14441 Check for integer overflow.
14442 (x_set_alpha): Do not assume XINT fits in int.
14444 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14445 This is for the members text_lines, text_cols, total_lines, total_cols,
14446 where the system imposes an 'int' limit.
14448 * fringe.c (Fdefine_fringe_bitmap):
14449 Don't update size until alloc works.
14451 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14452 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14454 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14455 Check for size-calculation overflow.
14456 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14457 do, as we prefer signed integers.
14458 (id_to_widget.max_size, id_to_widget.used)
14459 (xg_store_widget_in_map, xg_remove_widget_from_map)
14460 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14461 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14462 Use and return ptrdiff_t, not int.
14463 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14464 * gtkutil.h: Change prototypes to match the above.
14466 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14467 are duplicate now that they've been promoted to lisp.h.
14468 (x_allocate_bitmap_record, x_alloc_image_color)
14469 (make_image_cache, cache_image, xpm_load):
14470 Don't update size until alloc is done.

14481 Use ptrdiff_t, not int, to count maps.
14482 (read_char_minibuf_menu_prompt): Check for overflow in size
14483 calculations. Don't update size until allocation succeeds.
14484 Redo calculations to avoid overflow.
14485 * keyboard.h: Change prototypes to match the above.
14487 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
14489 (current_minor_maps): Check for size calculation overflow.
14490 * keymap.h: Change prototypes to match the above.
14492 * lread.c (read1, init_obarray): Don't update size until alloc done.
14494 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

14498 Now ptrdiff_t, not int.
14499 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

14511 (Fset_match_data): Don't assume list lengths fit in 'int'.
14513 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14514 for command line length. Do not attempt to address one before the
14515 beginning of an array, as that's not portable.
14517 * term.c (max_frame_lines): Remove; unused.
14518 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14520 (encode_terminal_code, calculate_costs): Check for size
14521 calculation overflow.

14527 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
14528 subtracting pointers.
14529 (gobble_line): Check for overflow more carefully. Don't update size
14532 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
14533 Don't update size until alloc done.
14534 Redo size calculations to avoid overflow.

14543 Use ptrdiff_t, not int, for sizes.
14544 (Finternal_make_lisp_face, cache_face):
14545 Check for size calculation overflow.
14546 (cache_face): Treat size calculation overflows as if they were
14547 memory exhaustion (the usual treatment), rather than aborting.
14549 * xfns.c (x_encode_text, x_set_name_internal)
14550 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14551 sizes, since they can exceed INT_MAX in size. Check for size
14552 calculation overflow.
14554 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
14555 (xg_select): Check for size calculation overflow.
14556 Don't update size until alloc done.
14558 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14559 as sprintf is limited to int lengths.
14561 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14562 (X_LONG_MIN): New macros.
14563 Use them to make the following changes clearer.
14564 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14565 This change doesn't affect the value now, but it may help remind
14566 future maintainers not to raise the value too much later.
14567 (SELECTION_QUANTUM): Remove, replacing with ...
14568 (selection_quantum): ... new function, which avoids overflow.
14570 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14571 assumption that selection length fits in 'int'.

14584 (lisp_data_to_selection_data, x_property_data_to_lisp):

14586 (x_get_window_property, receive_incremental_selection)
14587 (lisp_data_to_selection_data, Fx_register_dnd_atom):
14588 Don't store size until memory allocation succeeds.
14589 (x_get_window_property): Plug memory leak on memory exhaustion.
14590 Don't double-block input; malloc is safe here. Don't assume 2**34
14591 - 4 fits in unsigned long. Add an xassert to check
14592 XGetWindowProperty overflow. Be more careful about overflow
14593 calculations, and distinguish size from memory overflow better.
14594 (receive_incremental_selection): When tracing, don't assume
14595 unsigned int is less than INT_MAX.
14596 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14597 harmful) conversions of unsigned short to int.
14598 (lisp_data_to_selection_data): Don't assume that integers
14599 in the range -65535 through -1 fit in an X unsigned short.
14600 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14601 result parameters unless successful. Rely on cons_to_unsigned
14602 to report problems with elements; the old code wasn't right anyway.
14603 (x_check_property_data): Check for int overflow; we cannot use
14604 a wider type due to X limits.
14605 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
14607 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

14637 * lisp.h (hash_lookup, hash_put):
14638 * minibuf.c (Ftest_completion):
14639 Use ptrdiff_t for hash table indexes, not int (which is too
14640 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14641 32-bit --with-wide-int hosts).
14643 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14644 Add a FIXME comment about memory leaks.
14645 (syms_of_charset): Don't assume xmalloc returns.
14647 Don't assume that stated character widths fit in int.

14649 * character.h (CHAR_WIDTH):
14650 * indent.c (MULTIBYTE_BYTES_WIDTH):
14651 Use sanitize_char_width to avoid undefined and/or bad behavior
14652 with outlandish widths.
14653 * character.h (sanitize_tab_width): Rename from sanitize_width,
14654 now that we have two such functions. All uses changed.
14655 (sanitize_char_width): New inline function.
14657 Don't assume that tab-width fits in int.
14658 * character.h (sanitize_width): New inline function.

14665 * fileio.c: Integer overflow issues with file modes.
14666 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
14668 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

14673 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14674 (x_send_scroll_bar_event): Likewise. Check that the size does not
14675 exceed limits imposed by XClientMessageEvent, as well as the usual
14676 ptrdiff_t and size_t limits.
14678 * keyboard.c: Overflow, signedness and related fixes.
14679 (make_lispy_movement): Use same integer type in forward decl
14680 that is used in the definition.
14681 (read_key_sequence, keyremap_step):
14682 Change bufsize argument back to int, undoing my 2011-03-30 change.
14683 We prefer signed types, and int is wide enough here.
14684 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14685 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14686 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14687 length, not size_t. Use ptrdiff_t for index, not int.
14688 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14689 possibility of integer overflow.
14691 Overflow, signedness and related fixes for images.
14693 * dispextern.h (struct it.stack[0].u.image.image_id)

14701 * xdisp.c (calc_pixel_width_or_height):
14702 * xfns.c (image_cache_refcount):
14703 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

14712 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
14713 (lookup_image): Remove unnecessary tests.
14714 (xbm_image_p): Locals are now of int, not EMACS_INT,
14715 since parse_image_check makes sure they fit into int.
14716 (png_load, gif_load, svg_load_image):
14717 Prefer int to unsigned where either will do.
14718 (tiff_handler): New function, combining the cores of the
14719 old tiff_error_handler and tiff_warning_handler.
14720 This function is rewritten to use vsnprintf and thereby avoid
14721 stack buffer overflows. It uses only the features of vsnprintf
14722 that are common to both POSIX and native Microsoft.
14723 (tiff_error_handler, tiff_warning_handler): Use it.
14724 (tiff_load, gif_load, imagemagick_load_image):
14725 Don't assume :index value fits in 'int'.
14726 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14727 (imagemagick_load_image): Check that crop parameters fit into
14728 the integer types that MagickCropImage accepts. Don't assume
14729 Vimagemagick_render_type has a nonnegative value. Don't assume
14730 size_t fits in 'long'.
14731 (gs_load): Use printmax_t to print the widest integers possible.
14732 Check for integer overflow when computing image height and width.

14745 (handle_single_display_spec): If the display spec is of the form
14746 `(space ...)', and specifies display in the text area, return 2
14748 (try_cursor_movement): Check for the need to scroll more
14749 accurately, and prefer exact match for point under bidi.
14750 Don't advance `row' beyond the last row of the window.
14752 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
14753 into disp_prop; all users changed.

14803 * xdisp.c (redisplay_window): When computing centering_position,
14804 account for the height of the header line. (Bug#8874)
14806 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14807 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14808 candidate is selected by the mouse, and that candidate has a
14809 composed character under the mouse.
14811 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14812 coordinates reported by pos-visible-in-window-p for a composed
14813 character in column zero.

14823 composed buffer positions.
14825 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14827 * image.c (gif_load): Don't assume that each subimage has the same
14828 dimensions as the base image. Handle disposal method that is
14829 "undefined" by the gif spec (Bug#9335).
14831 2011-08-20 Chong Yidong <cyd@stupidchicken.com>

14839 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14840 from an Org mode buffer to a Speedbar frame.
14842 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14843 a composition, take its buffer position from IT->cmp_it.charpos.
14844 Fixes cursor positioning at the beginning of a line that begins
14845 with a composed character.
14847 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14849 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14850 character bidirectional type, use STRONG_L instead. Fixes crashes
14851 in a buffer produced by `describe-categories'.
14853 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14854 members before the level stack, so they would be saved and
14855 restored when copying iterator state. Fixes incorrect reordering
14856 around TABs covered by display properties.

14993 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14994 properties. (Bug#9284)

15195 * nsterm.h: Add declaration for ns_draw_text_decoration.
15197 * nsterm.m (ns_draw_text_decoration): New function for drawing
15198 underline, overline, and strike-through.
15199 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15200 ns_draw_text_decoration. Change treatment of cursor drawing to
15201 accommodate underlining, etc.
15203 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15205 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15208 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15210 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15211 Without this fix, if a signal arrives just after memory fills up,
15212 'malloc' might be invoked reentrantly.
15214 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15215 In other words, assume that every image size is allowed, on non-X
15216 hosts. This assumption is probably wrong, but it lets Emacs compile.
15218 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15220 * regex.c (re_iswctype): Convert return values to boolean.
15222 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15224 * xdisp.c (compute_display_string_pos): Don't use cached display
15225 string position if the buffer had its restriction changed.
15228 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15230 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15232 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15234 Integer signedness and overflow and related fixes. (Bug#9079)
15236 * bidi.c: Integer size and overflow fixes.
15237 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15238 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15239 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15240 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15241 (bidi_find_other_level_edge):
15242 Use ptrdiff_t instead of EMACS_INT where either will do.
15243 This works better on 32-bit hosts configured --with-wide-int.
15244 (bidi_cache_ensure_space): Check for size-calculation overflow.
15245 Use % rather than repeated addition, for better worst-case speed.
15246 Don't set bidi_cache_size until after xrealloc returns, because it
15248 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15249 (bidi_cache_ensure_space): Also check that the bidi cache size
15250 does not exceed that of the largest Lisp string or buffer. See Eli
15251 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15253 * alloc.c (__malloc_size_t): Remove.
15254 All uses replaced by size_t. See Andreas Schwab's note
15255 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15257 * image.c: Improve checking for integer overflow.
15258 (check_image_size): Assume that f is nonnull, since
15259 it is always nonnull in practice. This is one less thing to
15260 worry about when checking for integer overflow later.
15261 (x_check_image_size): New function, which checks for integer
15262 overflow issues inside X.
15263 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15264 This removes the need for a memory_full check.
15265 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15266 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15267 (xbm_read_bitmap_data): Change locals back to 'int', since
15268 their values must fit in 'int'.
15269 (xpm_load_image, png_load, tiff_load):
15270 Invoke x_create_x_image_and_pixmap earlier,
15271 to avoid much needless work if the image is too large.
15272 (tiff_load): Treat overly large images as if
15273 x_create_x_image_and_pixmap failed, not as malloc failures.
15274 (gs_load): Use x_check_image_size.
15276 * gtkutil.c: Omit integer casts.
15277 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15278 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15280 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15282 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15283 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15284 would wrongly return t on a 64-bit host.
15286 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15287 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15288 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15289 and therefore cause GCC to emit a bogus diagnostic in some cases.
15291 * image.c: Integer signedness and overflow and related fixes.
15292 This is not an exhaustive set of fixes, but it's time to
15293 record what I've got.
15294 (lookup_pixel_color, check_image_size): Remove redundant decls.
15295 (check_image_size): Don't assume that arbitrary EMACS_INT values
15296 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15297 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15298 (tiff_load, imagemagick_load_image):
15299 Check for overflow in size calculations.
15300 (x_create_x_image_and_pixmap): Remove unnecessary test for
15301 xmalloc returning NULL; that can't happen.
15302 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15303 (xpm_color_bucket): Use better integer hashing function.
15304 (xpm_cache_color): Don't possibly over-allocate memory.
15305 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15306 (gif_memory_source):
15307 Use ptrdiff_t, not int or size_t, to record sizes.
15308 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15309 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15310 either works, as we prefer signed integers.
15311 (tiff_read_from_memory, tiff_write_from_memory):
15312 Return tsize_t, not size_t, since that's what the TIFF API wants.
15313 (tiff_read_from_memory): Don't fail simply because the read would
15314 go past EOF; instead, return a short read.
15315 (tiff_load): Omit no-longer-needed casts.
15316 (Fimagemagick_types): Don't assume size fits into 'int'.
15318 Improve hashing quality when configured --with-wide-int.
15319 * fns.c (hash_string): New function, taken from sxhash_string.
15320 Do not discard information about ASCII character case; this
15321 discarding is no longer needed.
15322 (sxhash-string): Use it. Change sig to match it. Caller changed.
15323 * lisp.h: Declare it.
15324 * lread.c (hash_string): Remove, since we now use fns.c's version.
15325 The fns.c version returns a wider integer if --with-wide-int is
15326 specified, so this should help the quality of the hashing a bit.
15328 * emacs.c: Integer overflow minor fix.
15329 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15330 Define only if GNU_LINUX.
15331 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15333 * dispnew.c: Integer signedness and overflow fixes.
15334 Remove unnecessary forward decls, that were a maintenance hassle.
15335 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15337 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15338 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15339 (prepare_desired_row, line_draw_cost):
15340 Use int, not unsigned, where either works.
15341 (save_current_matrix, restore_current_matrix):
15342 Use ptrdiff_t, not size_t, where either works.
15343 (init_display): Check for overflow more accurately, and without
15344 relying on undefined behavior.
15346 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15347 Remove, replacing with the new symbols in lisp.h. All uses changed.
15348 * fileio.c (make_temp_name):
15349 * filelock.c (lock_file_1, lock_file):
15350 * xdisp.c (message_dolog):
15351 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15352 Use pMd etc. instead.
15353 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15354 replacing the pWIDE etc. symbols removed from editfns.c.
15356 * keyboard.h (num_input_events): Now uintmax_t.
15357 This is (very slightly) less likely to mess up due to wraparound.
15360 * buffer.c: Integer signedness fixes.
15361 (alloc_buffer_text, enlarge_buffer_text):
15362 Use ptrdiff_t rather than size_t when either will do, as we prefer
15365 * alloc.c: Integer signedness and overflow fixes.
15366 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15367 (__malloc_size_t): Default to size_t, not to int.
15368 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15369 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15370 Prefer ptrdiff_t to size_t when either would do, as we prefer
15372 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15373 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15374 Now const. Initialize with values that are in range even if char
15376 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15377 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15378 These functions do the right thing with sizes > 2**32.
15379 (check_depth): Now ptrdiff_t, not int.
15380 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15381 Adjust to new way of storing sizes. Check for size overflow bugs
15383 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15384 slightly wrong anyway, as it missed one instance of
15385 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15386 (refill_memory_reserve): Omit needless cast to size_t.
15387 (mark_object_loop_halt): Mark as externally visible.
15389 * xselect.c: Integer signedness and overflow fixes.
15390 (Fx_register_dnd_atom, x_handle_dnd_message):
15391 Use ptrdiff_t, not size_t, since we prefer signed.
15392 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15393 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15394 x_dnd_atoms_size and x_dnd_atoms_length.
15396 * doprnt.c: Prefer signed to unsigned when either works.
15398 * doprnt.c (doprnt):
15400 * xdisp.c (vmessage):
15401 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15402 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15403 prefer signed arithmetic to avoid comparison confusion.
15404 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15405 but is a bit tricky.
15407 Assume freestanding C89 headers, string.h, stdlib.h.
15408 * data.c, doprnt.c, floatfns.c, print.c:
15409 Include float.h unconditionally.
15410 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15411 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15412 * regex.c: Likewise for stddef.h, string.h.
15413 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15414 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15415 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15416 (STDC_HEADERS): Remove obsolete defines.
15417 * sysdep.c: Include limits.h unconditionally.
15419 Assume support for memcmp, memcpy, memmove, memset.
15420 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15421 * regex.c (memcmp, memcpy):
15422 Remove; we assume C89 now.
15424 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15425 (__malloc_safe_bcopy): Remove; no longer needed.
15427 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15428 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15429 well either way, and we prefer signed to unsigned.
15431 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15433 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15434 closes the connection while we're reading (bug#9182).
15436 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15438 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15439 are specified (Bug#9168).
15441 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15443 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15444 Found by GCC static checking and --with-wide-int on a 32-bit host.
15446 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15448 * xdisp.c (compute_display_string_pos): Fix logic of caching
15449 previous display string position. Initialize cached_prev_pos to
15450 -1. Fixes slow-down at the beginning of a buffer.
15452 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15454 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15455 for attrs[LFACE_FONTSET_INDEX].
15457 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15459 * xml.c (parse_region): Remove unused local
15460 that was recently introduced.
15462 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15464 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15465 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15467 * xdisp.c (move_it_in_display_line_to): Record the best matching
15468 position for TO_CHARPOS while scanning the line, and restore it on
15469 exit if none of the characters scanned was an exact match.
15470 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15471 when exact match is impossible due to invisible text, and the
15472 lines are truncated.
15474 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15476 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15479 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15481 Fix a significant slow-down of cursor motion with C-n, C-p,
15482 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15483 auto-repeat under bidi redisplay in fontified buffers.
15484 * xdisp.c (compute_stop_pos_backwards): New function.
15485 (next_element_from_buffer): Call compute_stop_pos_backwards to
15486 find a suitable prev_stop when we find ourselves before
15488 (reseat): Don't look for prev_stop, as that could mean a very long
15490 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15491 <cached_disp_overlay_modiff>: Cache for last found display string
15493 (compute_display_string_pos): Return the cached position if asked
15494 about the same buffer in the same area of character positions, and
15495 the buffer wasn't changed since the time the display string
15496 position was cached.
15498 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15500 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15501 is an integer, which is important for empty lines. (Bug#9149)
15503 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15505 * frame.c (Fmodify_frame_parameters): In tty case, update the
15506 default face if necessary (Bug#4238).
15508 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15510 * editfns.c (Fstring_to_char): No need to explain what a character
15511 is in the docstring (Bug#6576).
15513 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15515 * xml.c (parse_region): Make sure we always return a tree.
15517 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15519 * xml.c (parse_region): If a document contains only comments,
15522 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15524 * xml.c (make_dom): Return comments, too.
15526 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15529 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15530 and the surrounding thread.
15531 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15532 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15533 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15535 * s/openbsd.h (BROKEN_SIGIO): Define.
15536 * unexelf.c (unexec) [__OpenBSD__]:
15537 Don't update the .mdebug section of the Alpha COFF symbol table.
15539 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15541 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15544 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15546 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15547 This fixes some race conditions on the permissions of any newly
15550 * alloc.c (valid_pointer_p): Use pipe, not open.
15551 This fixes some permissions issues when debugging.
15553 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15554 If fchown fails to set both uid and gid, try to set just gid,
15555 as that is sometimes allowed. Adjust the file's mode to eliminate
15556 setuid or setgid bits that are inappropriate if fchown fails.
15558 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15560 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15561 to compare Lisp_Objects.
15562 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15563 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15564 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15566 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15568 * lread.c (read_integer): Unread even EOF character.
15569 (read1): Likewise. Properly record start position of symbol.
15571 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15572 symbol character follows.
15574 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15576 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15577 This works around a problem with the previous change to Fcopy_file.
15578 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15579 and without this change, GCC might complain about discarding
15580 fchown's return value.
15582 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15584 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15586 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15588 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15590 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15592 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15593 it's used from the C level.
15595 * process.c: Use the same condition for POLL_FOR_INPUT in both
15596 keyboard.c and process.c (bug#1858).
15598 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15600 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15601 (Fgnutls_boot): Use it.
15603 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15605 * doc.c (Fsubstitute_command_keys): Revert last change.
15607 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15609 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15610 quotes the next character, and doesn't affect other longer
15611 sequences (bug#8935).
15613 * lread.c (syms_of_lread): Clarify that is isn't only
15614 `eval-buffer' and `eval-defun' that's affected by
15615 `lexical-binding' (bug#8460).
15617 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15619 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15620 bidi redisplay when a line includes both an image and is truncated.
15622 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15624 Fix minor problems found by static checking.
15625 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15626 (elsz): Now a signed constant, not a size_t var. We prefer signed
15627 types to unsigned, to avoid integer comparison confusion. Without
15628 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15629 "cannot optimize loop, the loop counter may overflow", a symptom
15631 * indent.c (Fvertical_motion): Mark locals as initialized.
15632 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15634 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>

16156 (clone_per_buffer_values): Don't assume that

16158 This isn't true in general, and it's particularly not true
16159 if Emacs is configured with --with-wide-int.
16160 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16161 New macros, used in the buffer.c change.

16197 Random fixes. E.g., (random) never returned negative values.
16198 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16199 subseconds part to the entropy, as that's a bit more random.
16200 Prefer signed to unsigned, since the signedness doesn't matter and
16201 in general we prefer signed. When given a limit, use a
16202 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16203 latter isn't right if USE_2_TAGS_FOR_INTS.
16204 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16205 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16217 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16218 This is more efficient than Ffile_directory_p and avoids a minor race.

16222 * buffer.c (Foverlay_put): Say what the return value is
16225 * fileio.c (barf_or_query_if_file_exists): Check first if the file

16229 error be more correct.
16231 * fns.c (Frequire): Remove the mention of the .gz files, since
16232 that's installation-specific, but keep the mention of

16245 Qgnutls_bootprop_verify_error (which is no longer used).
16247 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16248 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16249 Also (re)move comments that are misplaced or no longer relevant.
16251 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16253 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

16278 * lread.c (syms_of_lread): Mention single symbols defined by

16350 * eval.c (struct backtrace): Simplify and port the data structure.
16351 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16352 signed bit field, as this assumption is not portable and it makes
16353 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16354 "char debug_on_exit : 1" as this is not portable either; instead,
16355 use the portable "unsigned int debug_on_exit : 1". Remove unused
16356 member evalargs. Remove obsolete comments about cc bombing out.
16358 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16512 * xmenu.c (syms_of_xmenu):
16513 * xsettings.c (syms_of_xsettings):
16514 * xterm.c (syms_of_xterm): Use DEFSYM.
16516 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
16518 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
16520 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
16522 Integer and buffer overflow fixes (Bug#8873).
16524 * print.c (printchar, strout): Check for string overflow.
16525 (PRINTPREPARE, printchar, strout):
16526 Don't set size unless allocation succeeds.
16528 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16529 for sizes. Check for string overflow more accurately.
16530 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
16532 * macros.c: Integer and buffer overflow fixes.
16533 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16534 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
16535 Use ptrdiff_t, not int, for sizes.
16536 Don't increment bufsize until after realloc succeeds.
16537 Check for size-calculation overflow.
16538 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16540 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16542 * lread.c: Integer overflow fixes.
16543 (read_integer): Radix is now EMACS_INT, not int,
16544 to improve quality of diagnostics for out-of-range radices.
16545 Calculate buffer size correctly for out-of-range radices.
16546 (read1): Check for integer overflow in radices, and in
16547 read-circle numbers.
16548 (read_escape): Avoid int overflow.
16549 (Fload, openp, read_buffer_size, read1)
16550 (substitute_object_recurse, read_vector, read_list, map_obarray):
16551 Use ptrdiff_t, not int, for sizes.
16552 (read1): Use EMACS_INT, not int, for sizes.
16553 Check for size overflow.
16555 * image.c (cache_image): Check for size arithmetic overflow.
16557 * lread.c: Integer overflow issues.
16558 (saved_doc_string_size, saved_doc_string_length)
16559 (prev_saved_doc_string_size, prev_saved_doc_string_length):
16560 Now ptrdiff_t, not int.
16561 (read1): Don't assume doc string length fits in int. Check for
16562 out-of-range doc string lengths.
16563 (read_list): Don't assume file position fits in int.
16564 (read_escape): Check for hex character overflow.
16566 2011-06-22 Leo Liu <sdl.web@gmail.com>
16568 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16569 Move to minibuffer.el.
16571 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16573 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16574 The following patches are for when GLYPH_DEBUG && !XASSERT.
16575 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16576 * dispnew.c (flush_stdout):
16577 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16578 Mark as externally visible.
16579 * dispnew.c (check_window_matrix_pointers): Now static.
16580 * dispnew.c (window_to_frame_vpos):
16581 * xfns.c (unwind_create_frame):
16582 * xterm.c (x_check_font): Remove unused local.
16583 * scroll.c (CHECK_BOUNDS):
16584 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16585 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16586 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16587 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16588 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16590 (debug_method_add): Use va_list and vsprintf rather than relying
16591 on undefined behavior with wrong number of arguments.
16592 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16593 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16594 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16595 since we're not interested in debugging glyphs with old libraries.
16596 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16597 GCC 4.6.0's static checking.
16599 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16601 Integer overflow and signedness fixes (Bug#8873).

16610 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
16611 (x_create_bitmap_from_xpm_data):
16612 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16613 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16615 * xfaces.c (load_pixmap):
16616 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16617 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16618 (.bitmaps_last, struct x_output.icon_bitmap):
16619 Use ptrdiff_t, not int, for bitmap indexes.
16620 (x_allocate_bitmap_record): Check for size overflow.
16621 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16623 Use ptrdiff_t, not int, for overlay counts.
16624 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16625 * editfns.c (overlays_around, get_pos_property):
16626 * textprop.c (get_char_property_and_overlay):
16627 * xdisp.c (next_overlay_change, note_mouse_highlight):
16628 * xfaces.c (face_at_buffer_position):
16629 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16630 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16631 (Fnext_overlay_change, Fprevious_overlay_change)
16632 (mouse_face_overlay_overlaps, Foverlays_in):
16633 Use ptrdiff_t, not int, for sizes.
16634 (overlays_at, overlays_in): Check for size-calculation overflow.
16636 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16638 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16639 (x_session_initialize): Do not assume string length fits in int.
16641 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16642 This is unlikely, but can occur if DPI is outlandish.
16644 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16645 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16647 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16648 * xrdb.c (magic_file_p, search_magic_path):
16649 Omit last arg SUFFIX; it was always 0. All callers changed.
16650 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16652 * xfont.c (xfont_match): Avoid need for strlen.
16654 * xfns.c: Don't assume strlen fits in int.
16655 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16657 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16658 not unsigned long, as we prefer signed integers. All callers changed.
16659 Detect integer overflow in repeat count.
16660 (message_dolog): Don't assume print length fits in 39 bytes.
16661 (display_mode_element): Don't assume strlen fits in int.
16663 * termcap.c: Don't assume sizes fit in int and never overflow.
16664 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16665 (gobble_line): Check for size-calculation overflow.
16667 * minibuf.c (Fread_buffer):
16668 * lread.c (intern, intern_c_string):
16669 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16670 Don't assume string length fits in int.
16672 * keyboard.c (parse_tool_bar_item):
16673 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16675 * font.c: Don't assume string length fits in int.
16676 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16677 Use ptrdiff_t, not int.
16678 (font_intern_prop): Don't assume string length fits in int.
16679 Don't assume integer property fits in fixnum.
16680 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16682 * filelock.c: Fix some buffer overrun and integer overflow issues.
16683 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16684 Reformulate so as not to need the command string.
16685 Invoke gzip -cd rather than gunzip, as it's more portable.
16686 (lock_info_type, lock_file_1, lock_file):
16687 Don't assume pid_t and time_t fit in unsigned long.
16688 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16689 (current_lock_owner): Prefer signed type for sizes.
16690 Use memcpy, not strncpy, where memcpy is what is really wanted.
16691 Don't assume (via atoi) that time_t and pid_t fit in int.
16692 Check for time_t and/or pid_t out of range, e.g., via a network share.
16693 Don't alloca where an auto var works fine.
16695 * fileio.c: Fix some integer overflow issues.
16696 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16697 Don't assume string length fits in int.
16698 (directory_file_name): Don't assume string length fits in long.
16699 (make_temp_name): Don't assume pid fits in int, or that its print
16700 length is less than 20.
16702 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16704 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16706 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16708 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16709 We prefer signed integers, even for size calculations.
16711 * emacs.c: Don't assume string length fits in 'int'.
16712 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16713 (main): Don't invoke strlen when not needed.
16715 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16716 (XD_DEBUG_MESSAGE): Don't waste a byte.
16718 * callproc.c (getenv_internal_1, getenv_internal)
16719 (Fgetenv_internal):
16720 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16722 * lread.c (invalid_syntax): Omit length argument.
16723 All uses changed. This doesn't fix a bug, but it simplifies the
16724 code away from its former Hollerith-constant appearance, and it's
16725 one less 'int' to worry about when looking at integer-overflow issues.
16726 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16728 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16729 This didn't break anything, but it didn't help either.
16730 It's confusing to put a bogus integer in a place where the actual
16731 value does not matter.
16732 (LIST_END_P): Remove unused macro and its bogus comment.
16733 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16735 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16736 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16738 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16739 We prefer signed types, and the value cannot exceed the EMACS_INT
16740 range anyway (because otherwise the length would not be representable).
16741 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16742 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16743 This avoids a GCC warning when WIDE_EMACS_INT.
16745 * indent.c (sane_tab_width): New function.
16746 (current_column, scan_for_column, Findent_to, position_indentation)
16747 (compute_motion): Use it. This is just for clarity.
16748 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16750 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16752 * lisp.h (lint_assume): New macro.
16753 * composite.c (composition_gstring_put_cache):
16754 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16756 * editfns.c, insdel.c:
16757 Omit unnecessary forward decls, to simplify future changes.
16759 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16761 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16763 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16764 Use much-faster test for byte-length change.
16765 Don't assume string byte-length fits in 'int'.
16766 Check that character arg fits in 'int'.
16767 (mapcar1): Declare byte as byte, for clarity.
16769 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16771 * fns.c (concat): Catch string overflow earlier.
16772 Do not rely on integer wraparound.
16774 * dispextern.h (struct it.overlay_strings_charpos)
16775 (struct it.selective): Now EMACS_INT, not int.
16776 * xdisp.c (forward_to_next_line_start)
16777 (back_to_previous_visible_line_start)
16778 (reseat_at_next_visible_line_start, next_element_from_buffer):
16779 Don't arbitrarily truncate the value of 'selective' to int.
16781 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16783 * composite.c: Don't truncate sizes to 'int'.
16784 (composition_gstring_p, composition_reseat_it)
16785 (composition_adjust_point): Use EMACS_INT, not int.
16786 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16787 not EMACS_UINT, for indexes.
16789 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16791 * buffer.c: Include <verify.h>.
16792 (struct sortvec.priority, struct sortstr.priority):
16793 Now EMACS_INT, not int.
16794 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16795 (struct sortstr.size, record_overlay_string)
16796 (struct sortstrlist.size, struct sortlist.used):
16797 Don't truncate size to int.
16798 (record_overlay_string): Check for size-calculation overflow.
16799 (init_buffer_once): Check at compile-time, not run-time.
16801 2011-06-22 Jim Meyering <meyering@redhat.com>
16803 Don't leak an XBM-image-sized buffer
16804 * image.c (xbm_load): Free the image buffer after using it.
16806 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16809 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16810 that Sun C diagnosed.
16811 * fns.c (secure_hash): Fix pointer signedness issue.
16812 * intervals.c (static_offset_intervals): New function.
16813 (offset_intervals): Use it.
16815 2011-06-21 Leo Liu <sdl.web@gmail.com>
16818 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16821 * fns.c (secure_hash): Rename from crypto_hash_function and change
16822 the first arg to accept symbols.
16823 (Fsecure_hash): New primitive.
16824 (syms_of_fns): New symbols.
16826 2011-06-20 Deniz Dogan <deniz@dogan.se>
16828 * process.c (Fset_process_buffer): Clarify return value in
16831 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16833 * dispnew.c (add_window_display_history): Use BVAR.
16835 * xdisp.c (debug_method_add): Use BVAR.
16836 (check_window_end, dump_glyph_matrix, dump_glyph)
16837 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16839 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16842 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16843 check till after the cache is created in init_frame_faces.
16845 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16847 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16849 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16851 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16852 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16853 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16855 Improve buffer-overflow checking (Bug#8873).
16856 * fileio.c (Finsert_file_contents):
16857 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16858 Remove the old (too-loose) buffer overflow checks.
16859 They weren't needed, since make_gap checks for buffer overflow.
16860 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16861 The old code merely checked for Emacs fixnum overflow, and relied
16862 on undefined (wraparound) behavior. The new code avoids undefined
16863 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16865 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16866 Tune. Don't use wider integers than needed. Don't use alloca.
16867 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16869 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16871 * insdel.c, lisp.h (buffer_overflow): New function.
16872 (insert_from_buffer_1, replace_range, replace_range_2):
16873 * insdel.c (make_gap_larger):
16874 * editfns.c (Finsert_char):
16875 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16877 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16879 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16881 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16883 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16884 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16886 * fileio.c: Don't assume EMACS_INT fits in off_t.
16887 (emacs_lseek): New static function.
16888 (Finsert_file_contents, Fwrite_region): Use it.
16889 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16891 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16893 * fns.c: Don't overflow int when computing a list length.
16894 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16895 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16896 truncation on 64-bit hosts. Check for QUIT every
16897 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16898 faster and is responsive enough.
16899 (Flength): Report an error instead of overflowing an integer.
16900 (Fsafe_length): Return a float if the value is not representable
16901 as a fixnum. This shouldn't happen except in contrived situations.
16902 (Fnthcdr, Fsort): Don't assume list length fits in int.
16903 (Fcopy_sequence): Don't assume vector length fits in int.
16905 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16906 (header_size, word_size): New constants.
16907 (allocate_vectorlike): Don't check size overflow here.
16908 (allocate_vector): Check it here instead, since this is the only
16909 caller of allocate_vectorlike that could cause overflow.
16910 Check that the new vector's length is representable as a fixnum.
16912 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16913 The previous code was bogus. For example, next_almost_prime (32)
16914 returned 39, which is undesirable as it is a multiple of 3; and
16915 next_almost_prime (24) returned 25, which is a multiple of 5 so
16916 why was the code bothering to check for multiples of 7?
16918 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16920 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16922 Variadic C functions now count arguments with ptrdiff_t.
16923 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16924 Back then I didn't know that the Emacs coding style prefers signed int.
16925 Also, in the meantime I found a few more instances where arguments
16926 were being counted with int, which may truncate counts on 64-bit
16927 machines, or EMACS_INT, which may be unnecessarily wide.
16928 * lisp.h (struct Lisp_Subr.function.aMANY)
16929 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16930 Arg counts are now ptrdiff_t, not size_t.
16931 All variadic functions and their callers changed accordingly.
16932 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16933 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16934 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16935 * callint.c (Fcall_interactively): Check arg count for overflow,
16936 to avoid potential buffer overrun. Use signed char, not 'int',
16937 for 'varies' array, so that we needn't bother to check its size
16938 calculation for overflow.
16939 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16940 * eval.c (apply_lambda):
16941 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16942 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16943 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16945 * callint.c (Fcall_interactively): Don't use index var as event count.
16947 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16948 * mem-limits.h (SIZE): Remove; no longer used.
16950 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16952 Remove unnecessary casts.
16953 * xterm.c (x_term_init):
16954 * xfns.c (x_set_border_pixel):
16955 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16956 These aren't needed now that we assume ANSI C.
16958 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16959 It's more likely to cause problems (due to unsigned overflow)
16962 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16964 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16966 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16968 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16970 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16972 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16974 GLYPH_CODE_FACE returns EMACS_INT, not int.
16975 * dispextern.h (merge_faces):
16976 * xfaces.c (merge_faces):
16977 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16978 Don't assume EMACS_INT fits in int.
16980 * character.h (CHAR_VALID_P): Remove unused parameter.
16981 * fontset.c, lisp.h, xdisp.c: All uses changed.
16983 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16985 * fns.c (concat): Minor tuning based on overflow analysis.
16986 This doesn't fix any bugs. Use int to hold character, instead
16987 of constantly refetching from Emacs object. Use XFASTINT, not
16988 XINT, for value known to be a character. Don't bother comparing
16989 a single byte to 0400, as it's always less.
16991 * floatfns.c (Fexpt):
16992 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16994 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16997 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16999 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17000 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17001 incorrectly succeed when S was a string, because 4294967386 was
17002 truncated before it was used.
17004 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17005 Otherwise, an out-of-range integer could cause undefined behavior
17008 * composite.c: Use int, not EMACS_INT, for characters.
17009 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17010 EMACS_INT, for values that are known to be in character range.
17011 This doesn't fix any bugs but is the usual style inside Emacs and
17012 may generate better code on 32-bit machines.
17014 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17015 This is for reasons similar to the recent CHAR_STRING fix.
17016 * charset.c (Fencode_char): Check that character arg is actually
17017 a character. Pass an int to ENCODE_CHAR.
17018 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17019 wider than 'int', as a compile-time check to prevent future regressions
17022 * character.c (char_string): Remove unnecessary casts.
17024 Make sure a 64-bit char is never passed to CHAR_STRING.
17025 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17026 by silently ignoring the top 32 bits, allowing some values
17027 that were far too large to be valid characters.
17028 * character.h: Include <verify.h>.
17029 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17030 arguments are no wider than unsigned, as a compile-time check
17031 to prevent future regressions in this area.
17033 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17034 (Fsubst_char_in_region):
17036 * xdisp.c (decode_mode_spec_coding):
17037 Adjust to CHAR_STRING's new requirement.
17038 * editfns.c (Finsert_char, Fsubst_char_in_region):
17039 * fns.c (concat): Check that character args are actually
17040 characters. Without this test, these functions did the wrong
17041 thing with wildly out-of-range values on 64-bit hosts.
17043 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17044 These casts should not be needed on 32-bit hosts, either.
17045 * keyboard.c (read_char):
17046 * lread.c (Fload): Remove casts to unsigned.
17048 * lisp.h (UNSIGNED_CMP): New macro.
17049 This fixes comparison bugs on 64-bit hosts.
17050 (ASCII_CHAR_P): Use it.
17051 * casefiddle.c (casify_object):
17052 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17053 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17054 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17055 * dispextern.h (FACE_FROM_ID):
17056 * keyboard.c (read_char): Use UNSIGNED_CMP.
17058 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17059 not to EMACS_INT, to avoid GCC warning.
17061 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17063 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17064 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17065 isn't needed on 32-bit machines.
17067 * buffer.c (Fgenerate_new_buffer_name):
17068 Use EMACS_INT for count, not int.
17069 (advance_to_char_boundary): Return EMACS_INT, not int.
17071 * data.c (Qcompiled_function): Now static.
17073 * window.c (window_body_lines): Now static.
17075 * image.c (gif_load): Rename local to avoid shadowing.
17077 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17078 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17079 * alloc.c (make_save_value): Integer argument is now of type
17080 ptrdiff_t, not int.
17081 (mark_object): Use ptrdiff_t, not int.
17082 * lisp.h (pD): New macro.
17083 * print.c (print_object): Use it.
17085 * alloc.c: Use EMACS_INT, not int, to count objects.
17086 (total_conses, total_markers, total_symbols, total_vector_size)
17087 (total_free_conses, total_free_markers, total_free_symbols)
17088 (total_free_floats, total_floats, total_free_intervals)
17089 (total_intervals, total_strings, total_free_strings):
17090 Now EMACS_INT, not int. All uses changed.
17091 (Fgarbage_collect): Compute overall total using a double, so that
17092 integer overflow is less likely to be a problem. Check for overflow
17093 when converting back to an integer.
17094 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17095 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17096 These were 'int' variables that could overflow on 64-bit hosts;
17097 they were never used, so remove them instead of repairing them.
17098 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17099 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17100 Previously, this ceilinged at INT_MAX, but that doesn't work on
17102 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17104 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17105 (allocate_vectorlike): Check for ptrdiff_t overflow.
17106 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17107 when a (possibly-narrower) signed value would do just as well.
17108 We prefer using signed arithmetic, to avoid comparison confusion.
17110 * alloc.c: Catch some string size overflows that we were missing.
17111 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17112 for convenience in STRING_BYTES_MAX.
17113 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17114 The definition here is exact; the one in lisp.h was approximate.
17115 (allocate_string_data): Check for string overflow. This catches
17116 some instances we weren't catching before. Also, it catches
17117 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17118 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17119 and ptrdiff_t and EMACS_INT are both 64 bits.
17121 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17122 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17123 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17125 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17127 * alloc.c (Fmake_string): Check for out-of-range init.
17129 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17131 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17133 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17135 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17136 xg_get_default_scrollbar_width.
17138 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17139 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17140 (style_changed_cb): Call update_theme_scrollbar_width and call

17146 and height if HAVE_GTK3 (Bug#8505).
17147 (scroll_bar_width_for_theme): New variable.
17148 (update_theme_scrollbar_width): New function.
17149 (xg_get_default_scrollbar_width): Move code to
17150 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17151 (xg_initialize): Call update_theme_scrollbar_width.
17153 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17155 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17157 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17159 * frame.c (make_frame): Call other_buffer_safely instead of
17162 * window.c (temp_output_buffer_show): Call display_buffer with
17163 second argument Vtemp_buffer_show_specifiers and reset latter
17164 immediately after the call.
17165 (Vtemp_buffer_show_specifiers): New variable.
17166 (auto_window_vscroll_p, next_screen_context_lines)
17167 (Vscroll_preserve_screen_position): Remove leading asterisks from

17213 (Fset_window_configuration): Rewrite to handle dead buffers and
17214 consequently deletable windows.
17215 (window_tree, Fwindow_tree): Remove. Supply functionality in

17350 Remove static from declaration of Qdelete_window, it's
17351 temporarily needed by Fbury_buffer.
17352 (replace_window): Don't assign orig_top_line and

17356 (window_loop): Remove DELETE_OTHER_WINDOWS case.
17357 Replace Fdelete_window calls with calls to Qdelete_window.
17358 (Fdelete_other_windows): Remove. Deleting other windows is

17763 * gnutls.c: Use Emacs's memory allocators.
17764 Without this change, the gnutls library would invoke malloc etc.
17765 directly, which causes problems on non-SYNC_INPUT hosts, and which
17766 runs afoul of improving memory_full behavior. (Bug#8761)
17767 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17768 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17769 xfree instead of the default malloc, realloc, free.
17770 (Fgnutls_boot): No need to check for memory allocation failure,
17771 since xmalloc does that for us.

17800 need to be updated by these changes.
17801 * fns.c (make_hash_table, maybe_resize_hash_table):
17802 Check for integer overflow with large hash tables.
17803 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17804 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17805 (SXHASH_REDUCE): New macro.
17806 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17807 Use it instead of discarding useful hash info with large hash values.

17809 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17810 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17811 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17812 Rewrite to use FIXNUM_BITS, as this simplifies things.
17813 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17814 Adjust signatures to match updated version of code.
17815 (consing_since_gc): Now EMACS_INT, since a single hash table can
17816 use more than INT_MAX bytes.
17818 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
17820 Make it possible to build with GCC-4.6+ -O2 -flto.
17822 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
17824 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
17826 * minibuf.c (get_minibuffer, read_minibuf_unwind):
17827 Call minibuffer-inactive-mode.
17829 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
17831 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
17832 Update dependencies.
17834 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17836 * data.c (init_data): Remove code for UTS, this system is not
17839 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17841 Don't force ./temacs to start in terminal mode.
17843 * frame.c (make_initial_frame): Initialize faces in all cases, not
17844 only when CANNOT_DUMP is defined.
17845 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17847 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17849 * dispnew.c (add_window_display_history): Use const for the string
17850 pointer. Remove declaration, not needed.
17852 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17854 Use 'inline', not 'INLINE'.
17855 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17856 * alloc.c, fontset.c (INLINE): Remove.
17857 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17858 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17859 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17860 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17861 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17863 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17865 Make it possible to run ./temacs.
17867 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17868 syms_of_callproc does the same thing. Remove test for
17869 "initialized", do it in the caller.
17870 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17872 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17874 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17875 (read_minibuf): Use get_minibuffer.
17876 (syms_of_minibuf): Use DEFSYM.
17877 (Qmetadata): New var.
17878 * data.c (Qbuffer): Don't make it static.
17879 (syms_of_data): Use DEFSYM.
17881 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17883 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17884 (CCL_CODE_MIN): New macro.
17886 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17888 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17890 * eval.c (Qdebug): Now static.
17891 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17892 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17893 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17895 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17897 * image.c: Various fixes to ImageMagick code comments.
17898 (Fimagemagick_types): Doc fix.
17900 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17902 Minor fixes prompted by GCC 4.6.0 warnings.
17904 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17906 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17907 (x_clipboard_manager_save_all): Move extern decl to ...
17908 * xterm.h: ... here, so that it can be checked for consistency.
17910 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17912 * xselect.c (x_clipboard_manager_save_frame)
17913 (x_clipboard_manager_save_all): New functions.
17914 (Fx_clipboard_manager_save): Lisp function deleted.
17916 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17917 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17919 * xterm.h: Update prototype.
17921 2011-05-28 William Xu <william.xwl@gmail.com>
17923 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17924 exiting (Bug#8239).
17926 2011-05-28 Jim Meyering <meyering@redhat.com>
17928 Avoid a sign-extension bug in crypto_hash_function.
17929 * fns.c (to_uchar): Define.
17930 (crypto_hash_function): Use it to convert some newly-signed
17931 variables to unsigned, to avoid sign-extension bugs. For example,
17932 without this change, (md5 "truc") would evaluate to
17933 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17934 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17935 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17937 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17939 Integer overflow fixes.
17941 * dbusbind.c: Serial number integer overflow fixes.
17942 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17943 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17944 to hold a serial number that is too large for a fixnum.
17945 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17946 Check for serial numbers out of range. Decode any serial number
17947 that was so large that it became a float. (Bug#8722)
17949 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17950 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17951 Use XFASTINT rather than XUINT when numbers are nonnegative.
17952 (xd_append_arg, Fdbus_method_return_internal):
17953 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17954 arguments, check that Lisp number is nonnegative, rather than
17955 silently wrapping negative numbers around. (Bug#8722)
17956 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17959 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17961 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17963 ccl: Add integer overflow checks.
17964 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17965 (IN_INT_RANGE): New macros.
17966 (ccl_driver): Use them to check for integer overflow when
17967 decoding a CCL program. Many of the new checks are whether XINT (x)
17968 fits in int; it doesn't always, on 64-bit hosts. The new version
17969 doesn't catch all possible integer overflows, but it's an
17970 improvement. (Bug#8719)
17972 * alloc.c (make_event_array): Use XINT, not XUINT.
17973 There's no need for unsigned here.
17975 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17976 This follows up to the 2011-05-06 change that substituted uintptr_t
17977 for EMACS_INT. This case wasn't caught back then.
17979 Rework Fformat to avoid integer overflow issues.
17980 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17981 now (part of C89). Include <verify.h>.
17982 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17983 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17984 (Fformat): Avoid the prepass trying to compute sizes; it was only
17985 approximate and thus did not catch overflow reliably. Instead, walk
17986 through the format just once, formatting and computing sizes as we go,
17987 checking for integer overflow at every step, and allocating a larger
17988 buffer as needed. Keep track separately whether the format is
17989 multibyte. Keep only the most-recently calculated precision, rather
17990 than them all. Record whether each argument has been converted to
17991 string. Use EMACS_INT, not int, for byte and char and arg counts.
17992 Support field widths and precisions larger than INT_MAX. Avoid
17993 sprintf's undefined behavior with conversion specifications such as %#d
17994 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17995 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17996 formatting out-of-range floating point numbers with int
17997 formats. (Bug#8668)
17999 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18001 * data.c: Avoid integer truncation in expressions involving floats.
18002 * data.c: Include <intprops.h>.
18003 (arith_driver): When there's an integer overflow in an expression
18004 involving floating point, convert the integers to floating point
18005 so that the resulting value does not suffer from catastrophic
18006 integer truncation. For example, on a 64-bit host (* 4
18007 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18008 Do not rely on undefined behavior after integer overflow.
18010 merge count_size_as_multibyte, parse_str_to_multibyte
18011 * character.c, character.h (count_size_as_multibyte):
18012 Rename from parse_str_to_multibyte; all uses changed.
18013 Check for integer overflow.
18014 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18015 since it's now a duplicate of the other. This is more of
18016 a character than a buffer op, so better that it's in character.c.
18017 * fns.c, print.c: Adjust to above changes.
18019 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18021 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18023 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18025 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18026 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18027 (x_clipboard_manager_save): Now static.
18028 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18030 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18031 (crypto_hash_function): Now static.
18032 Fix pointer signedness problems. Avoid unnecessary initializations.
18034 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18036 * termhooks.h (Vselection_alist): Make it terminal-local.
18038 * terminal.c (create_terminal): Initialize it.
18040 * xselect.c: Support for clipboard managers.
18041 (Vselection_alist): Move to termhooks.h as terminal-local var.
18042 (LOCAL_SELECTION): New macro.
18043 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18044 (symbol_to_x_atom): Remove gratuitous arg.
18045 (x_handle_selection_request, lisp_data_to_selection_data)
18046 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18047 (x_own_selection, x_get_local_selection, x_convert_selection):
18048 New arg, specifying work frame. Use terminal-local Vselection_alist.
18049 (some_frame_on_display): Delete unused function.
18050 (Fx_own_selection_internal, Fx_get_selection_internal)
18051 (Fx_disown_selection_internal, Fx_selection_owner_p)
18052 (Fx_selection_exists_p): New optional frame arg.
18053 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18054 (x_handle_selection_clear): Don't treat other terminals with the
18055 same keyboard specially. Use the terminal-local Vselection_alist.
18056 (x_clear_frame_selections): Use Frun_hook_with_args.
18058 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18060 * xterm.h: Add support for those atoms.
18062 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18064 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18065 (converted_selections, conversion_fail_tag): New global variables.
18066 (x_selection_request_lisp_error): Free the above.
18067 (x_get_local_selection): Remove unnecessary code.
18068 (x_reply_selection_request): Args changed; handle arbitrary array
18069 of converted selections stored in converted_selections.
18070 Separate the XChangeProperty and SelectionNotify steps.
18071 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18072 (x_convert_selection): New function.
18073 (x_handle_selection_event): Simplify.
18074 (x_get_foreign_selection): Don't ignore incoming requests while
18075 waiting for an answer; this will fail when we implement
18076 SAVE_TARGETS, and seems unnecessary anyway.
18077 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18078 (Vx_sent_selection_functions): Doc fix.
18080 2011-05-26 Leo Liu <sdl.web@gmail.com>
18082 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18084 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18086 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18088 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18089 for fringe update if it has periodic bitmap.
18090 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18091 and fringe_bitmap_periodic_p.
18093 * fringe.c (get_fringe_bitmap_data): New function.
18094 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18095 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18096 row. Mark glyph row for fringe update if periodicity changed.
18098 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18099 for fringe update unless it has periodic bitmap.
18101 2011-05-25 Kenichi Handa <handa@m17n.org>
18103 * xdisp.c (get_next_display_element): Set correct it->face_id for
18104 a static composition.
18106 2011-05-24 Leo Liu <sdl.web@gmail.com>
18109 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18111 * fns.c (crypto_hash_function, Fsha1): New function.
18112 (Fmd5): Use crypto_hash_function.
18113 (syms_of_fns): Add Ssha1.
18115 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18117 * gnutls.c: Remove unused macros.
18118 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18119 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18120 Remove macros that are defined and never used.
18121 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18123 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18125 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18126 (Fx_get_selection_internal): Minor cleanup.
18127 (Fx_own_selection_internal): Rename arguments for consistency with
18130 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18132 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18134 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18136 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18138 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18140 * dispnew.c (scrolling_window): Don't exclude the case that the
18141 last enabled row in the desired matrix touches the bottom boundary.
18143 2011-05-21 Glenn Morris <rgm@gnu.org>
18145 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18146 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18147 and add some more files.
18149 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18151 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18152 report_file_error introduced by the change from 2011-05-07.
18154 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18156 * systime.h (Time): Define only if emacs is defined.
18157 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18158 where the include path doesn't have X11/X.h by default. See
18159 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18161 2011-05-20 Kenichi Handa <handa@m17n.org>
18163 * composite.c (find_automatic_composition): Fix previous change.
18165 2011-05-20 Glenn Morris <rgm@gnu.org>
18167 * lisp.mk: New file, split from Makefile.in.
18168 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18169 (shortlisp): Remove.
18170 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18172 2011-05-19 Glenn Morris <rgm@gnu.org>
18174 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18175 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18176 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18177 (lisp): Set the order to that of loadup.el.
18178 (shortlisp): Make it a copy of $lisp.
18179 (SOME_MACHINE_LISP): Remove.
18180 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18181 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18183 2011-05-18 Kenichi Handa <handa@m17n.org>
18185 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18186 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18187 (find_automatic_composition): Mostly rewrite for efficiency.
18189 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18191 * makefile.w32-in: Update dependencies.
18193 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18195 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18196 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18198 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18200 Fix some integer overflow issues, such as string length overflow.
18202 * insdel.c (count_size_as_multibyte): Check for string overflow.
18204 * character.c (lisp_string_width): Check for string overflow.
18205 Use EMACS_INT, not int, for string indexes and lengths; in
18206 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18207 the resulting string length overflows an EMACS_INT; instead,
18208 report a string overflow if no precision given. When checking for
18209 precision exhaustion, use a check that cannot possibly have
18210 integer overflow. (Bug#8675)
18211 * character.h (lisp_string_width): Adjust to new signature.
18213 * alloc.c (string_overflow): New function.
18214 (Fmake_string): Use it. This doesn't change behavior, but saves
18215 a few bytes and will simplify future changes.
18216 * character.c (string_escape_byte8): Likewise.
18217 * lisp.h (string_overflow): New decl.
18219 Fixups, following up to the user-interface timestamp change.
18220 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18221 for UI timestamps, instead of unsigned long.
18222 * msdos.c (mouse_get_pos): Likewise.
18223 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18224 * w32gui.h (Time): Define by including "systime.h" rather than by
18225 declaring it ourselves. (Bug#8664)
18227 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18228 * image.c (clear_image_cache): Likewise.
18230 * term.c (term_mouse_position): Don't assume time_t wraparound.
18232 Be more systematic about user-interface timestamps.
18233 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18234 and sometimes 'EMACS_UINT', to represent these timestamps.
18235 This change causes it to use 'Time' uniformly, as that's what X uses.
18236 This makes the code easier to follow, and makes it easier to catch
18237 integer overflow bugs such as Bug#8664.
18238 * frame.c (Fmouse_position, Fmouse_pixel_position):
18239 Use Time, not unsigned long, for user-interface timestamps.
18240 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18241 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18242 * keyboard.h (last_event_timestamp): Likewise.
18243 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18244 * menu.h (xmenu_show): Likewise.
18245 * term.c (term_mouse_position): Likewise.
18246 * termhooks.h (struct input_event.timestamp): Likewise.
18247 (struct terminal.mouse_position_hook): Likewise.
18248 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18249 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18250 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18251 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18252 what it was before.
18253 * menu.h, termhooks.h: Include "systime.h", for Time.
18255 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18256 Don't assume that the difference between two unsigned long values
18257 can fit into an integer. At this point, we know button_down_time
18258 <= event->timestamp, so the difference must be nonnegative, so
18259 there's no need to cast the result if double-click-time is
18260 nonnegative, as it should be; check that it's nonnegative, just in
18261 case. This bug is triggered when events are more than 2**31 ms
18262 apart (about 25 days). (Bug#8664)
18264 * xselect.c (last_event_timestamp): Remove duplicate decl.
18265 (x_own_selection): Remove needless cast to unsigned long.
18267 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18268 that always fit in int. Use a sentinel instead of a counter, to
18269 avoid a temp and to allay GCC's concerns about possible int overflow.
18270 * frame.h (struct frame): Use int for menu_bar_items_used
18271 instead of EMACS_INT, since it always fits in int.
18273 * menu.c (grow_menu_items): Check for int overflow.
18275 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18277 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18278 Before, the code was not consistent. These values cannot exceed
18279 2**31 - 1 so there's no need to make them unsigned.
18280 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18281 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18282 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18284 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18286 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18287 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18288 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18289 presumably because the widths might not match.
18291 * window.c (size_window): Avoid needless test at loop start.
18293 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18295 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18297 2011-05-12 Drew Adams <drew.adams@oracle.com>
18299 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18301 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18303 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18304 `width' to `bar_area_x' and `bar_area_width', respectively.
18305 (x_scroll_run): Take account of fringe background extension.
18307 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18308 Rename local vars `left' and `width' to `bar_area_x' and
18309 `bar_area_width', respectively.
18310 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18311 background extension.
18313 2011-05-10 Jim Meyering <meyering@redhat.com>
18315 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18317 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18319 * image.c (Finit_image_library): Return t for built-in image types,
18320 like pbm and xbm. (Bug#8640)
18322 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18324 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18326 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18328 * w32console.c (Fset_screen_color): Doc fix.
18329 (Fget_screen_color): New function.
18330 (syms_of_ntterm): Defsubr it.
18332 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18333 unlink the temporary file if Fcall_process didn't create it in the
18335 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18336 child process will be redirected to a file specified with `:file'.
18337 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18338 cue to call_process_cleanup not to close that handle.
18340 2011-05-07 Ben Key <bkey76@gmail.com>
18342 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18343 one of two shell specific rules, either bootstrap-temacs-CMD or
18344 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18345 to the previous implementation of the bootstrap-temacs rule.
18346 The bootstrap-temacs-CMD rule is similar to the previous
18347 implementation of the bootstrap-temacs rule except that it
18348 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18351 These changes, along with some changes to nt/configure.bat,
18352 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18353 earlier fix to add support for --cflags and --ldflags options
18354 that include quotes so that it works whether make uses cmd or
18357 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18359 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18360 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18362 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18363 a string. Handle both cases.
18364 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18365 (Fdbus_register_method): Use Qinvalid_function.
18367 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18369 * makefile.w32-in: Update dependencies.
18370 (LISP_H): Add inttypes.h and stdin.h.
18371 (PROCESS_H): Add unistd.h.
18373 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18375 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18376 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18378 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18380 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18382 * term.c (vfatal): Remove stray call to va_end.
18383 It's not needed and the C Standard doesn't allow it here anyway.
18385 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18386 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18388 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18391 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18393 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18395 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18397 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18399 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18401 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18402 * charset.c (Fdefine_charset_internal): Don't initialize
18403 charset.code_space[15]. The value was garbage, on hosts with
18404 32-bit int (Bug#8600).
18406 * lread.c (read_integer): Be more consistent with string-to-number.
18407 Use string_to_number to do the actual conversion; this avoids
18408 rounding errors and fixes some other screwups. Without this fix,
18409 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18410 (digit_to_number): Move earlier, for benefit of read_integer.
18411 Return -1 if the digit is out of range for the base, -2 if it is
18412 not a digit in any supported base. (Bug#8602)
18414 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18416 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18417 to match comment at start of function. This also removes a
18418 GCC warning about overflow in a 32+64-bit port.
18420 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18422 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18423 Reported by Stefan Monnier in
18424 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18425 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18426 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18428 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18429 (EMACS_UINTPTR): Likewise, with uintptr_t.
18431 * lisp.h: Prefer 64-bit EMACS_INT if available.
18432 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18433 on 32-bit hosts that have 64-bit int, so that they can access
18435 However, temporarily disable this change unless the temporary
18436 symbol WIDE_EMACS_INT is defined.
18438 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18440 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18441 This removes an assumption that EMACS_INT and long are the same
18442 width as pointers. The assumption is true for Emacs porting targets
18443 now, but we want to make other targets possible.
18444 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18445 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18446 In the rest of the code, change types of integers that hold casted
18447 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18448 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18449 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18450 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18451 No need to cast type when ORing.
18452 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18453 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18454 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18455 assume EMACS_INT is the same width as char *.
18456 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18457 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18458 Remove no-longer-needed casts.
18459 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18460 (xg_tool_bar_help_callback, xg_make_tool_item):
18461 Use EMACS_INTPTR to hold an integer
18462 that will be cast to void *; this can avoid a GCC warning
18463 if EMACS_INT is not the same width as void *.
18464 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18465 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18466 (current_message_1, set_message_1):
18467 Use a local to convert to proper width without a cast.
18468 * xmenu.c (dialog_selection_callback): Likewise.
18470 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18471 Also, don't assume VALBITS / RAND_BITS is less than 5,
18472 and don't rely on undefined behavior when shifting a 1 left into
18474 * lisp.h (get_random): Change signature to match.
18476 * lread.c (hash_string): Use size_t, not int, for hash computation.
18477 Normally we prefer signed values; but hashing is special, because
18478 it's better to use unsigned division on hash table sizes so that
18479 the remainder is nonnegative. Also, size_t is the natural width
18480 for hashing into memory. The previous code used 'int', which doesn't
18481 retain enough info to hash well into very large tables.
18482 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18484 * dbusbind.c: Don't possibly lose pointer info when converting.
18485 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18486 Use XPNTR rather than XHASH, so that the high-order bits of
18487 the pointer aren't lost when converting through void *.
18489 * eval.c (Fautoload): Don't double-shift a pointer.
18491 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18493 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18495 * gnutls.c (DEF_GNUTLS_FN):
18496 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18498 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18500 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18503 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18505 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18506 New version that can reserve upto 2GB of heap space.
18508 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18510 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18512 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18514 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18515 `gnutls_certificate_set_x509_key_file'.
18517 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18519 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18520 Update dependencies.
18522 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18524 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18525 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18526 Remove unused parameter `fildes'.
18527 * process.c (read_process_output, send_process): Don't pass it.
18529 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18531 Fix previous change: the library cache is defined in w32.c.
18532 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18533 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18535 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18537 Implement dynamic loading of GnuTLS on Windows.
18539 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18540 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18541 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18544 * gnutls.c (Qgnutls_dll): Define.
18545 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18546 (gnutls_*): Declare function pointers.
18547 (init_gnutls_functions): New function to initialize function pointers.
18548 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
18549 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
18550 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18551 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18552 (emacs_gnutls_write, emacs_gnutls_read)
18553 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18554 (Fgnutls_available_p): New function.
18555 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
18556 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
18557 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18559 * image.c: Include w32.h.
18560 (Vimage_type_cache): Delete.
18561 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
18562 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18563 (w32_delayed_load): Move to w32.c.
18565 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18567 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18568 (w32_delayed_load): Move from image.c. When loading a library, record
18569 its filename in the :loaded-from property of the library id.
18570 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18571 Initialize and staticpro them.
18572 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18574 * process.c: Include lisp.h before w32.h, not after.
18575 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18576 instead of gnutls_record_check_pending.
18578 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18580 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18582 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18583 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18586 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18588 * xterm.c (x_set_frame_alpha): Do not set property on anything
18589 else than FRAME_X_OUTER_WINDOW (Bug#8608).
18591 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18593 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)

18597 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
18598 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

18604 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
18605 (Qgnutls_bootprop_callbacks_verify): Make static.
18607 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
18609 * callproc.c: Indentation fixup.
18611 * sysdep.c (wait_for_termination_1): Make static.
18612 (wait_for_termination, interruptible_wait_for_termination):
18613 Move after wait_for_termination_1.
18615 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18617 * sysdep.c (interruptible_wait_for_termination): New function
18618 which is like wait_for_termination, but allows keyboard
18621 * callproc.c (Fcall_process): Add (:file "file") as an option for
18623 (Fcall_process_region): Ditto.
18625 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18627 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18628 rather than `XVECTOR (FOO)->size'.
18630 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18631 inttypes.h, as a gnulib replacement is used if it not available in
18634 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18636 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18637 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18638 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18640 * coding.c (coding_alloc_by_realloc): Error out if destination
18641 will grow beyond MOST_POSITIVE_FIXNUM.
18642 (decode_coding_emacs_mule): Abort if there isn't enough place in
18643 charbuf for the composition carryover bytes. Reserve an extra
18644 space for up to 2 characters produced in a loop.
18645 (decode_coding_iso_2022): Abort if there isn't enough place in
18646 charbuf for the composition carryover bytes.

18651 aborting when %lld or %lll format is passed.
18652 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18653 %llo or %llx format is passed. (Bug#8545)
18655 * window.c (window_scroll_line_based): Use a marker instead of
18656 simple variables to record original value of point. (Bug#7952)
18658 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18659 produced by %s or %c overflows available buffer space. (Bug#8545)
18661 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18663 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18664 (SIZE_MAX): Move defn after all includes, as they might #define it.
18666 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18668 * w32.c (init_environment): Warn about defaulting HOME to C:\.
18670 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

18674 if Vdelayed_warnings_list is non-nil.
18675 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18676 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18678 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18680 * doprnt.c (doprnt): Don't return value smaller than the buffer
18681 size if the message was truncated. (Bug#8545).
18683 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18685 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18686 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18688 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18690 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18692 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18694 * makefile.w32-in: Update dependencies.
18696 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18698 Improve `doprnt' and its usage. (Bug#8545)
18699 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18700 `format_end'. Remove support for %l as a conversion specifier.
18701 Don't use xrealloc. Improve diagnostics when the %l size modifier
18702 is used. Update the commentary.
18704 * eval.c (verror): Simplify calculation of size_t.
18706 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18709 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18711 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18714 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18716 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18717 This makes this file independent of the recent pseudovector change.
18719 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18721 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18723 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18724 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18725 Remove unused local.
18726 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18728 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18729 GCC 4.6.0 optimizes based on type-based alias analysis.
18730 For example, if b is of type struct buffer * and v of type struct
18731 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18732 != &v->size, and therefore "v->size = 1; b->size = 2; return
18733 v->size;" must therefore return 1. This assumption is incorrect
18734 for Emacs, since it type-puns struct Lisp_Vector * with many other
18735 types. To fix this problem, this patch adds a new type struct
18736 vectorlike_header that documents the constraints on layout of vectors
18737 and pseudovectors, and helps optimizing compilers not get fooled
18738 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18739 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18740 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18742 (XSETPVECTYPE): Rewrite in terms of new macro.
18743 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18744 This is a bit clearer, and further avoids the possibility of
18745 undesirable aliasing.
18746 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18747 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18748 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18749 since Lisp_Subr is a special case (no "next" field).
18750 (ASIZE): Now uses header.size rather than size.
18751 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18752 to avoid the hassle of writing XVECTOR (foo)->header.size.
18753 (struct vectorlike_header): New type.
18754 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18755 object, to help avoid aliasing.
18756 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18757 (SUBRP): Likewise, since Lisp_Subr is a special case.
18758 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18759 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18760 (struct Lisp_Hash_Table): Combine first two members into a single
18761 struct vectorlike_header member. All uses of "size" and "next" members
18762 changed to be "header.size" and "header.next".
18763 * buffer.h (struct buffer): Likewise.
18764 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18765 * frame.h (struct frame): Likewise.
18766 * process.h (struct Lisp_Process): Likewise.
18767 * termhooks.h (struct terminal): Likewise.
18768 * window.c (struct save_window_data, struct saved_window): Likewise.
18769 * window.h (struct window): Likewise.
18770 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18771 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18772 * buffer.c (init_buffer_once): Likewise.
18773 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18775 * process.c (Fformat_network_address): Use local var for size,
18778 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18780 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18781 * data.c (atof): Remove decl; no longer used or needed.
18782 (digit_to_number): Move to lread.c.
18783 (Fstring_to_number): Use new string_to_number function, to be
18784 consistent with how the Lisp reader treats infinities and NaNs.
18785 Do not assume that floating-point numbers represent EMACS_INT
18786 without losing information; this is not true on most 64-bit hosts.
18787 Avoid double-rounding errors, by insisting on integers when
18788 parsing non-base-10 numbers, as the documentation specifies.
18789 * lisp.h (string_to_number): New decl, replacing ...
18790 (isfloat_string): Remove.
18791 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18792 (read1): Do not accept +. and -. as integers; this
18793 appears to have been a coding error. Similarly, do not accept
18794 strings like +-1e0 as floating point numbers. Do not report
18795 overflow for integer overflows unless the base is not 10 which
18796 means we have no simple and reliable way to continue.
18797 Break out the floating-point parsing into a new
18798 function string_to_number, so that Fstring_to_number parses
18799 floating point numbers consistently with the Lisp reader.
18800 (digit_to_number): Move here from data.c. Make it static inline.
18801 (E_CHAR, EXP_INT): Remove, replacing with ...
18802 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18803 (string_to_number): New function, replacing isfloat_string.
18804 This function checks for valid syntax and produces the resulting
18805 Lisp float number too. Rework it so that string-to-number
18806 no longer mishandles examples like "1.0e+". Use strtoumax,
18807 so that overflow for non-base-10 numbers is reported only when
18808 there's no portable and simple way to convert to floating point.
18810 * textprop.c (set_text_properties_1): Rewrite for clarity,
18811 and to avoid GCC warning about integer overflow.
18813 * intervals.h (struct interval): Use EMACS_INT for members
18814 where EMACS_UINT might cause problems. See
18815 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18816 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18817 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18819 (offset_intervals): Tell GCC not to worry about length overflow
18820 when negating a negative length.
18822 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18823 (overrun_check_free): Likewise.
18825 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18826 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18829 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18830 (gnutls_make_error): Rename local to avoid shadowing.
18831 (gnutls_emacs_global_deinit): ifdef out; not used.
18832 (Fgnutls_boot): Use const for pointer to readonly storage.
18833 Comment out unused local. Fix pointer signedness problems.
18835 * lread.c (openp): Don't stuff size_t into an 'int'.
18836 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18837 about possible signed overflow.
18839 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18840 (GDK_KEY_g): Don't define if already defined.
18841 (xg_prepare_tooltip): Avoid pointer signedness problem.
18842 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18844 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18845 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18847 * xfns.c (Fx_window_property): Simplify a bit,
18848 to make a bit faster and to avoid GCC 4.6.0 warning.
18849 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18851 * fns.c (internal_equal): Don't assume size_t fits in int.
18853 * alloc.c (compact_small_strings): Tighten assertion a little.
18855 Replace pEd with more-general pI, and fix some printf arg casts.
18856 * lisp.h (pI): New macro, generalizing old pEd macro to other
18857 conversion specifiers. For example, use "...%"pI"d..." rather
18858 than "...%"pEd"...".
18859 (pEd): Remove. All uses replaced with similar uses of pI.
18860 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18861 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18862 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18863 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18864 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18865 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18866 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18868 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18869 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18870 * print.c (safe_debug_print, print_object): Likewise.
18871 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18873 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18874 avoiding the 0 flag, which is not portable.
18875 * process.c (Fmake_network_process): Use pI to avoid cast.
18876 * region-cache.c (pp_cache): Likewise.
18877 * xdisp.c (decode_mode_spec): Likewise.
18878 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18879 behavior on 64-bit hosts with printf arg.
18880 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18881 (x_stop_queuing_selection_requests): Likewise.
18882 (x_get_window_property): Don't truncate byte count to an 'int'
18885 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18886 here, since it parses constructs like leading '-' and spaces,
18887 which are not wanted; and it overflows with large numbers.
18888 Instead, simply match F[0-9]+, which is what is wanted anyway.
18890 * alloc.c: Remove unportable assumptions about struct layout.
18891 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18892 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18893 (allocate_vectorlike, make_pure_vector): Use the new macros,
18894 plus offsetof, to remove unportable assumptions about struct layout.
18895 These assumptions hold on all porting targets that I know of, but
18896 they are not guaranteed, they're easy to remove, and removing them
18897 makes further changes easier.
18899 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18900 This doesn't fix a bug but makes the code clearer.
18901 (string_overrun_cookie): Now const. Use initializers that
18902 don't formally overflow signed char, to avoid warnings.
18903 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18904 can cause Emacs to crash when string overrun checking is enabled.
18905 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18906 multiple of sizeof (EMACS_INT); it need not be, if
18907 alignof(EMACS_INT) < sizeof (EMACS_INT).
18908 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18910 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18914 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
18916 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
18917 supposed to be handshaking. (Bug#8556)
18918 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18920 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
18922 * lisp.h (Qdebug): List symbol.
18923 * eval.c (Qdebug): Restore global linkage.

18925 (handle_user_signal): Break into debugger when debug-on-event
18926 matches the current signal symbol.
18928 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
18930 * alloc.c (check_sblock, check_string_bytes)
18931 (check_string_free_list): Convert to standard C.
18933 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18935 * w32.c (emacs_gnutls_push): Fix typo.
18937 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18939 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18940 "cast to pointer from integer of different size".
18942 Improve doprnt and its use in verror. (Bug#8545)
18943 * doprnt.c (doprnt): Document the set of format control sequences
18944 supported by the function. Use SAFE_ALLOCA instead of always
18947 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18948 is one byte too soon. Don't use xrealloc; instead xfree and
18951 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18953 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18956 * gnutls.c: Renamed global_initialized to
18957 gnutls_global_initialized. Added internals for the
18958 :verify-hostname-error, :verify-error, and :verify-flags
18959 parameters of `gnutls-boot' and documented those parameters in the
18960 docstring. Start callback support.
18961 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18962 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18963 on error. Return error code.
18964 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18965 (emacs_gnutls_read): Likewise.
18966 (Fgnutls_boot): Return handshake error code.
18967 (emacs_gnutls_handle_error): New function.
18968 (wsaerror_to_errno): Likewise.

19030 <char-direction-table>: Deleted.
19032 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19034 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19035 * doprnt.c: Include limits.h.
19036 (SIZE_MAX): New macro.
19037 (doprnt): Return a size_t value. 2nd arg is now size_t.
19038 Many local variables are now size_t instead of int or unsigned.
19039 Improve overflow protection. Support `l' modifier for integer
19040 conversions. Support %l conversion. Don't assume an EMACS_INT
19041 argument for integer conversions and for %c.
19043 * lisp.h (doprnt): Restore prototype.
19045 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19046 $(SRC)/character.h.
19048 * Makefile.in (base_obj): Add back doprnt.o.
19050 * deps.mk (doprnt.o): Add back prerequisites.
19051 (callint.o): Depend on character.h.
19053 * eval.c (internal_lisp_condition_case): Include the handler
19054 representation in the error message.
19055 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19056 when breaking from the loop.
19058 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19060 * callint.c (Fcall_interactively): When displaying error message
19061 about invalid control letter, pass the character's codepoint, not
19062 a pointer to its multibyte form. Improve display of the character
19063 in octal and display also its hex code.
19065 * character.c (char_string): Use %x to display the (unsigned)
19066 codepoint of an invalid character, to avoid displaying a bogus
19069 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19070 `error', not SYMBOL_NAME itself.
19072 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19073 character arguments to `error'.
19075 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19076 to `error' in error message about FINAL_CHAR argument. Make sure
19077 FINAL_CHAR is a character, and use %c when it is passed as
19078 argument to `error'.

19142 Define only if needed.
19144 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
19145 by pacifying GCC about it. Maybe it's time to retire it?
19146 * xfaces.c (USG, __TIMEVAL__): Likewise.
19148 * dispextern.h (struct redisplay_interface): Rename param
19149 to avoid shadowing.

19198 out-of-range initializers by using, for example, '\xab' rather
19201 * xgselect.c (xgselect_initialize): Check vs interface
19202 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

19267 * nsfont.m: Fixed bugs in ns_get_family and
19268 ns_descriptor_to_entity that were caused by using free to
19269 deallocate memory blocks that were allocated by xmalloc (via
19270 xstrdup). This caused Emacs to crash when compiled with
19271 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
19272 --enable-checking=xmallocoverrun). xfree is now used to
19273 deallocate these memory blocks.

19287 (emacs_read, emacs_write): Remove check for negative size, as the
19288 Emacs source code has been audited now.
19289 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
19290 (emacs_read, emacs_write): Use it.
19291 * process.c (send_process): Adjust to the new signatures of
19292 emacs_write and emacs_gnutls_write. Do not attempt to store
19293 a byte offset into an 'int'; it might overflow.
19294 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

19628 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
19629 * dispextern.h (bidi_dump_cached_states): Remove, since it's
19630 exported only to the debugger.

19633 * atimer.h (run_all_atimers): Remove; not exported.
19635 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
19636 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
19637 was inaccessible from Lisp.
19638 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
19639 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
19641 alloc.c: Import and export fewer symbols, and remove unused items.
19642 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
19644 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
19645 it's not optimized away by whole-program optimization.

19658 (mark_backtrace): Define only if BYTE_MARK_STACK.
19659 * xdisp.c (message_enable_multibyte): Now static.
19661 Declare Lisp_Object Q* variables to be 'static' if not exported.
19662 This makes it easier for human readers (and static analyzers)
19663 to see whether these variables are used from other modules.
19664 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

19675 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
19677 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19679 Make Emacs functions such as Fatom 'static' by default.
19680 This makes it easier for human readers (and static analyzers)
19681 to see whether these functions can be called from other modules.
19682 DEFUN now defines a static function. To make the function external
19683 so that it can be used in other C modules, use the new macro DEFUE.

19689 Remove decls, since these functions are now static.
19690 (Funintern, Fget_internal_run_time): New decls, since these functions
19691 were already external.

19701 Mark functions with DEFUE instead of DEFUN,
19702 if they are used in other modules.

19704 decls for now-static functions.
19705 * buffer.h (Fdelete_overlay): Remove decl.

19741 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19743 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init

19756 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19757 (overrun_check_free): Protoize.
19759 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19761 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19762 since callers should never pass a negative size.
19763 Change the signature to match that of plain 'read' and 'write'; see
19764 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19765 * lisp.h: Update prototypes of emacs_write and emacs_read.
19767 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19769 * xdisp.c (redisplay_window): Don't try to determine the character
19770 position of the scroll margin if the window start point w->startp
19771 is outside the buffer's accessible region. (Bug#8468)
19773 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19775 Fix write-region and its subroutines for buffers > 2GB.
19776 * fileio.c (a_write, e_write): Modify declaration of arguments and
19777 local variables to support buffers larger than 2GB.
19778 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19780 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19781 argument, local variables, and return value.
19783 * lisp.h: Update prototypes of emacs_write and emacs_read.
19785 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19787 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19789 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19791 Fix more problems found by GCC 4.6.0's static checks.
19793 * xdisp.c (vmessage): Use a better test for character truncation.
19795 * charset.c (load_charset_map): <, not <=, for optimization,
19796 and to avoid potential problems with integer overflow.
19797 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19798 * casetab.c (set_identity, shuffle): Likewise.
19799 * editfns.c (Fformat): Likewise.
19800 * syntax.c (skip_chars): Likewise.
19802 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19803 This also lets GCC 4.6.0 generate slightly better loop code.
19805 * callint.c (Fcall_interactively): <, not <=, for optimization.
19806 (Fcall_interactively): Count the number of arguments produced,
19807 not the number of arguments given. This is simpler and lets GCC
19808 4.6.0 generate slightly better code.
19810 * ftfont.c: Distingish more carefully between FcChar8 and char.
19811 The previous code passed unsigned char * to a functions like
19812 strlen and xstrcasecmp that expect char *, which does not
19813 conform to the C standard.
19814 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19815 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19816 char * when the C standard requires it.
19818 * keyboard.c (read_char): Remove unused var.
19820 * eval.c: Port to Windows vsnprintf (Bug#8435).
19821 Include <limits.h>.
19822 (SIZE_MAX): Define if the headers do not.
19823 (verror): Do not give up if vsnprintf returns a negative count.
19824 Instead, grow the buffer. This ports to Windows vsnprintf, which
19825 does not conform to C99. Problem reported by Eli Zaretskii.
19826 Also, simplify the allocation scheme, by avoiding the need for
19827 calling realloc, and removing the ALLOCATED variable.
19829 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19831 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19832 But keep the doprint source code for now, as we might revamp it
19833 and use it again (Bug#8435).
19834 * lisp.h (doprnt): Remove.
19835 * Makefile.in (base_obj): Remove doprnt.o.
19836 * deps.mk (doprnt.o): Remove.
19838 error: Print 32- and 64-bit integers portably (Bug#8435).
19839 Without this change, on typical 64-bit hosts error ("...%d...", N)
19840 was used to print both 32- and 64-bit integers N, which relied on
19841 undefined behavior.
19842 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19843 * lisp.h (error, verror): Mark as printf-like functions.
19844 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19845 Report overflow in size calculations when allocating printf buffer.
19846 Do not truncate output string at its first null byte.
19847 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19848 Truncate the output at a character boundary, since vsnprintf does not
19850 * charset.c (check_iso_charset_parameter): Convert internal
19851 character to string before calling 'error', since %c now has the
19853 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19854 overflow when computing char to be passed to 'error'. Do not
19855 pass Lisp_Object to 'error'; pass the integer instead.
19856 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19857 formatted with plain %d.
19859 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19861 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19863 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19865 * xterm.c (x_catch_errors): Remove duplicate declaration.
19867 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19869 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19871 2011-04-10 Jim Meyering <meyering@redhat.com>
19873 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19874 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19875 return ssize_t not "int", and use size_t as the buffer length.
19876 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19877 * gnutls.h: Update declarations.
19878 * process.c (read_process_output): Use ssize_t, to match.
19879 (send_process): Likewise.
19881 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19883 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19885 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19887 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19888 Use unsigned char, to match FcChar8 type definition.
19890 * xterm.c (handle_one_xevent):
19891 * xmenu.c (create_and_show_popup_menu):
19892 * xselect.c (x_decline_selection_request)
19893 (x_reply_selection_request): Avoid type-punned deref of X events.
19895 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19897 Fix some uses of `int' instead of EMACS_INT.
19898 * search.c (string_match_1, fast_string_match)
19899 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19900 (scan_buffer, find_next_newline_no_quit)
19901 (find_before_next_newline, search_command, Freplace_match)
19902 (Fmatch_data): Make some `int' variables be EMACS_INT.
19904 * xdisp.c (display_count_lines): 3rd argument and return value now
19905 EMACS_INT. All callers changed.
19906 (pint2hrstr): Last argument is now EMACS_INT.
19908 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19909 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19910 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

19924 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19925 (encode_invocation_designation): Last argument P_NCHARS is now
19927 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19928 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19930 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19933 * ccl.c (Fccl_execute_on_string): Declare some variables
19936 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19938 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19940 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19942 * process.c (Fformat_network_address): Doc fix.
19944 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19946 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19948 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19950 * keyboard.c (read_char): Call Lisp function help-form-show,
19951 instead of using internal_with_output_to_temp_buffer.
19952 (Qhelp_form_show): New var.
19953 (syms_of_keyboard): Use DEFSYM macro.
19955 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19962 (list_processes_1): Delete.
19964 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19966 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19968 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19970 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19972 Fix more problems found by GCC 4.6.0's static checks.

19994 This avoids several warnings with gcc -Wstrict-overflow.
19995 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19996 directly, rather than having caller test rule sign. This avoids
19997 some unnecessary tests.
19998 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19999 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20000 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20002 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20003 (xfont_open): Avoid unnecessary tests.
20005 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20007 * composite.h, composite.c (composition_gstring_put_cache):
20008 Use EMACS_INT, not int, for length.
20010 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20011 breaking out part of COMPOSITION_DECODE_RULE.
20012 (COMPOSITION_DECODE_RULE): Use it.
20013 * composite.c (get_composition_id): Remove unused local vars,
20014 by using the new macro.
20016 * textprop.c (set_text_properties_1): Change while to do-while,
20017 since the condition is always true at first.
20019 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20020 (interval_deletion_adjustment): Return unsigned value.
20023 * process.c (list_processes_1, create_pty, read_process_output):
20024 (exec_sentinel): Remove vars that were set but not used.
20025 (create_pty): Remove unnecessary "volatile"s.
20026 (Fnetwork_interface_info): Avoid possibility of int overflow.
20027 (read_process_output): Do adaptive read buffering even if carryover.
20028 (read_process_output): Simplify nbytes computation if buffered.

20036 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
20037 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
20039 * print.c (print_error_message): Avoid int overflow.
20041 * font.c (font_list_entities): Redo for clarity,
20042 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20044 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20045 (font_score): Avoid potential overflow in diff calculation.
20047 * fns.c (substring_both): Remove var that is set but not used.
20048 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20050 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20052 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20053 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20054 can always succeed if overflow has undefined behavior.
20056 * search.c (boyer_moore, wordify): Remove vars set but not used.
20057 (wordify): Omit three unnecessary tests.
20059 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20060 All callers changed. This avoids the need for an unused var.
20062 * casefiddle.c (casify_region): Remove var that is set but not used.
20064 * dired.c (file_name_completion): Remove var that is set but not used.
20066 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20068 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20069 (Finsert_file_contents): Remove unnecessary code checking fd.
20071 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20072 Check for integer overflow on size calculations.
20074 * buffer.c (Fprevious_overlay_change): Remove var that is set
20077 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20078 Remove vars that are set but not used.
20079 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20080 (timer_check_2): Mark vars as initialized.
20082 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20084 * image.c (lookup_image): Remove var that is set but not used.
20085 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20087 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20088 that are set but not used.
20090 * xfns.c (make_invisible_cursor): Don't return garbage
20091 if XCreateBitmapFromData fails (Bug#8410).
20093 * xselect.c (x_get_local_selection, x_handle_property_notify):
20094 Remove vars that are set but not used.
20096 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20097 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20099 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20100 Remove var that is set but not used.
20101 (scroll_bar_windows_size): Now size_t, not int.
20102 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20103 Check for overflow.
20105 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20106 (map_tty_color) [!defined MSDOS]: Likewise.
20108 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20110 * coding.c: Remove vars that are set but not used.
20111 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20112 All callers changed.
20113 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20114 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20115 (decode_coding_charset): Remove vars that are set but not used.
20117 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20118 that is set but not used.
20120 * print.c (print_object): Remove var that is set but not used.
20122 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20123 The gnulib version avoids calling malloc in the usual case,
20124 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20125 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20126 * filelock.c (current_lock_owner): Likewise.
20127 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20128 * sysdep.c: Include allocator.h, careadlinkat.h.
20129 (emacs_no_realloc_allocator): New static constant.
20130 (emacs_readlink): New function.
20131 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20132 ../lib/careadlinkat.h.
20134 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20136 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20137 first non-nil return value).
20139 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
20141 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
20142 if not defined (Bug#8403).
20144 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20146 * xdisp.c (display_count_lines): Remove parameter `start',
20147 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20148 (get_char_face_and_encoding): Remove parameter `multibyte_p',
20149 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

20151 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20152 and thereabouts. All callers changed.
20153 (get_per_char_metric): Remove parameter `f', unused since
20154 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20156 2011-04-02 Jim Meyering <meyering@redhat.com>
20158 do not dereference NULL upon failed strdup
20159 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20160 (ns_get_family): Likewise.
20162 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20164 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20166 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20168 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20171 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20173 Add lexical binding.
20175 * window.c (Ftemp_output_buffer_show): New fun.
20176 (Fsave_window_excursion):
20177 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20179 * lread.c (lisp_file_lexically_bound_p): New function.
20180 (Fload): Bind Qlexical_binding.
20181 (readevalloop): Remove `evalfun' arg.
20182 Bind Qinternal_interpreter_environment.
20183 (Feval_buffer): Bind Qlexical_binding.
20184 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20186 (syms_of_lread): Declare `lexical-binding'.
20188 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20190 * keyboard.c (eval_dyn): New fun.
20191 (menu_item_eval_property): Use it.
20193 * image.c (parse_image_spec): Use Ffunctionp.
20195 * fns.c (concat, mapcar1): Accept byte-code-functions.
20197 * eval.c (Fsetq): Handle lexical vars.
20198 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20199 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20200 (FletX, Flet): Obey lexical binding.
20201 (Fcommandp): Handle closures.
20202 (Feval): New `lexical' arg.
20203 (eval_sub): New function extracted from Feval. Use it almost
20204 everywhere where Feval was used. Look up vars in lexical env.
20206 (Ffunctionp): Move from subr.el.
20207 (Ffuncall): Handle closures.
20208 (apply_lambda): Remove `eval_flags'.
20209 (funcall_lambda): Handle closures and new byte-code-functions.
20210 (Fspecial_variable_p): New function.
20211 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20212 but without exporting it to Lisp.
20214 * doc.c (Fdocumentation, store_function_docstring):
20215 * data.c (Finteractive_form): Handle closures.
20217 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20220 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20222 (exec_byte_code): New function extracted from Fbyte_code to handle new
20223 calling convention for byte-code-functions. Add new byte-codes.
20225 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20227 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20229 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20231 * xdisp.c (redisplay_internal): Fix prototype.
20233 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20235 * xdisp.c (SCROLL_LIMIT): New macro.
20236 (try_scrolling): Use it when setting scroll_limit.
20237 Limit scrolling to 100 screen lines.
20238 (redisplay_window): Even when falling back on "recentering",
20239 position point in the window according to scroll-conservatively,
20240 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20242 (try_scrolling): When point is above the window, allow searching
20243 as far as scroll_max, or one screenful, to compute vertical
20244 distance from PT to the scroll margin position. This prevents
20245 try_scrolling from unnecessarily failing when
20246 scroll-conservatively is set to a value slightly larger than the
20247 window height. Clean up the case of PT below the margin at bottom
20248 of window: scroll_max can no longer be INT_MAX. When aggressive
20249 scrolling is in use, don't let point enter the opposite scroll
20250 margin as result of the scroll.
20251 (syms_of_xdisp) <scroll-conservatively>: Document the
20252 threshold of 100 lines for never-recentering scrolling.
20254 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20256 * dispextern.h (move_it_by_lines):
20257 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
20258 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
20259 (message_log_check_duplicate): Remove parameters `prev_bol' and
20260 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20261 (redisplay_internal): Remove parameter `preserve_echo_area',
20262 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20264 * indent.c (Fvertical_motion):
20265 * window.c (window_scroll_pixel_based, Frecenter):
20266 Don't pass `need_y_p' to `move_it_by_lines'.
20268 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20270 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20271 steal a few bits to be more compact.
20272 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20273 Remove unneeded casts.
20275 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20277 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20279 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20280 binding" message (bug#7967).
20282 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20284 Fix more problems found by GCC 4.6.0's static checks.
20286 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20287 Remove unused local var.
20289 * editfns.c (Fmessage_box): Remove unused local var.
20291 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20292 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20293 Omit unused local vars.
20294 * window.c (shrink_windows): Omit unused local var.
20295 * menu.c (digest_single_submenu): Omit unused local var.
20296 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20297 Omit unused local var.
20299 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20300 Don't assume string length fits in int.
20301 (keyremap_step, read_key_sequence): Use size_t for sizes.
20302 (read_key_sequence): Don't check last_real_key_start redundantly.
20304 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20305 instead of alloca (Bug#8344).
20307 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20308 (Fbacktrace_frame): Don't assume nframes fits in int.
20310 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20312 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20315 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20317 * cm.c (calccost): Turn while-do into do-while, for clarity.
20319 * keyboard.c (syms_of_keyboard): Use the same style as later
20320 in this function when indexing through an array. This also
20321 works around GCC bug 48267.
20323 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20325 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20327 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20328 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20330 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20331 This avoids undefined behavior on integer overflow, and is a bit
20332 more convenient anyway since it is compared to a size_t variable.
20334 Variadic C functions now count arguments with size_t, not int.
20335 This avoids an unnecessary limitation on 64-bit machines, which
20336 caused (substring ...) to crash on large vectors (Bug#8344).
20337 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20338 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

20346 * fns.c (concat): Likewise.
20347 * frame.c (x_set_frame_parameters): Likewise.
20348 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20349 0 if not found, not -1. All callers changed.
20351 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20352 (stack_copy_size): Now size_t, not int.
20353 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20355 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20357 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20358 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20359 All callers changed.
20361 * lisp.h (multibyte_char_to_unibyte):
20362 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20363 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

20374 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20375 don't set the hook to nil, but remove the offending function instead.
20376 (Qcommand_hook_internal): Remove, unused.
20377 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20378 Vcommand_hook_internal.
20380 * eval.c (enum run_hooks_condition): Remove.
20381 (funcall_nil, funcall_not): New functions.
20382 (run_hook_with_args): Call each function through a `funcall' argument.
20383 Remove `cond' argument, now redundant.

20396 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20397 All callers changed.
20399 * w32.c (_wsa_errlist): Use braces for struct initializers.
20401 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
20402 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
20403 All callers changed.

20548 * term.c (Fsuspend_tty, Fresume_tty):
20549 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
20550 * window.c (temp_output_buffer_show):

20558 * buffer.c (Fkill_all_local_variables):
20559 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20561 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20562 unconditionally since it does the check itself.
20564 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20566 Fix more problems found by GCC 4.5.2's static checks.
20568 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20569 the first time through the loop, since we know p0 < p1 then.
20570 This also avoids a gcc -Wstrict-overflow warning.
20572 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20573 leading to a memory leak, possible in functions like
20574 load_charset_map_from_file that can allocate an unbounded number
20575 of objects (Bug#8318).
20577 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20578 that could (at least in theory) be that large.
20580 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20581 This is less likely to overflow, and avoids undefined behavior if
20582 overflow does occur. All callers changed. Use strtoul to scan
20583 for the unsigned long integer.
20584 (pint2hrstr): Simplify and tune code slightly.
20585 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20595 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20598 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20600 * process.c (Fmake_network_process): Use socklen_t, not int,
20601 where POSIX says socklen_t is required in portable programs.
20602 This fixes a porting bug on hosts like 64-bit HP-UX, where
20603 socklen_t is wider than int (Bug#8277).
20604 (Fmake_network_process, server_accept_connection):
20605 (wait_reading_process_output, read_process_output):
20608 * process.c: Rename or move locals to avoid shadowing.

20618 Make tparam.h and terminfo.c consistent.
20619 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20620 Include tparam.h instead, since it declares them.
20621 * cm.h (PC): Remove extern decl; tparam.h now does this.
20622 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20623 * terminfo.c: Include tparam.h, to check interfaces.
20624 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20625 (tparam): Adjust signature to match interface in tparam.h;
20626 this removes some undefined behavior. Check that outstring and len
20627 are zero, which they always are with Emacs.
20628 * tparam.h (PC, BC, UP): New extern decls.
20630 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20631 (xftfont_open): Rename locals to avoid shadowing.
20633 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

20648 (find_automatic_composition, composition_adjust_point): Likewise.
20649 (composition_update_it): Mark var as initialized.
20650 (find_automatic_composition): Mark vars as initialized,
20651 with a FIXME (Bug#8290).

20655 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20656 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20657 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20658 to avoid shadowing.
20660 * textprop.c (property_change_between_p): Remove; unused.
20662 * intervals.c (interval_start_pos): Now static.
20664 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

20670 Fix pointer signedness.
20671 (alsa_choose_format): Remove unused local var.
20672 (wav_play): Initialize a variable to 0, to prevent undefined
20673 behavior (Bug#8278).
20675 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20677 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20679 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20680 clobbering (Bug#8298).
20681 * sysdep.c (sys_subshell): Likewise.
20682 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20684 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20685 This should get cleaned up, so that child_setup has the
20686 same signature on all platforms.
20688 * callproc.c (call_process_cleanup): Now static.
20689 (relocate_fd): Rename locals to avoid shadowing.
20691 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20693 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20694 not to be necessary, and produces flickering.
20696 2011-03-20 Glenn Morris <rgm@gnu.org>
20698 * config.in: Remove file.
20700 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20702 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20703 are now in src/globals.h.

20730 (sigchld_handler): Now static.
20732 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
20733 That way, the code declares only the vars that it needs.

20743 (CONSTANTLIM): Remove; unused.
20744 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
20745 Define only if needed.
20747 * unexelf.c (unexec): Name an expression,
20748 to avoid gcc -Wbad-function-cast warning.
20749 Use a different way to cause a compilation error if anyone uses
20750 n rather than nn, a way that does not involve shadowing.
20751 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20753 * deps.mk (unexalpha.o): Remove; unused.
20755 New file unexec.h, the (simple) interface for unexec (Bug#8267).

20822 (Ftranslate_region_internal, Fformat):
20823 Rename or remove local vars to avoid shadowing.

20826 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
20829 * lisp.h (eassert): Check that the argument compiles, even if
20830 ENABLE_CHECKING is not defined.
20832 * data.c (Findirect_variable): Name an expression, to avoid
20833 gcc -Wbad-function-cast warning.

20850 (Fmemory_limit): Cast sbrk's returned value to char *.

20876 (RETALLOC_IF): Define only if needed.
20877 (WORDCHAR_P): Likewise. This one is never needed, but is used
20878 only in a comment talking about a compiler bug, so put inside
20879 the #if 0 of that comment.

20909 gcpro1, gcpro2, etc.
20910 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20912 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second

20917 Rename locals to avoid shadowing.
20919 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

20928 (downcase, upcase1): New static inline functions.
20929 (DOWNCASE, UPCASE1): Reimplement using these functions.
20930 This avoids undefined behavior in expressions like

20964 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

20971 * buffer.c (fix_overlays_before): Mark locals as initialized.
20972 (fix_start_end_in_overlays): Likewise. This function should be
20973 simplified by using pointers-to-pointers, but that's a different

20982 to suppress a gcc -Wclobbered warning that does not seem to be right.
20983 (MAXPATHLEN): Define only if needed.
20985 * process.c (serial_open, serial_configure): Move decls from here ...
20986 * systty.h: ... to here, so that they can be checked.

21332 a block, when the outer 'i' will do.

21345 -Wuninitialized does not deduce are never used uninitialized.
21346 (detect_coding_iso_2022): Initialize a local variable that might
21347 be used uninitialized. Leave a FIXME because it's not clear that
