57 * insdel.c (move_gap): Remove.
58 (move_gap_both): Add eassert.
59 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.

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

69 switches from 'signal' to 'pthread_sigmask', which is safer in
70 multithreaded applications.
71 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
72 which has already arranged for that.
73 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
74 This is the main part of the bug fix.
76 2013-01-10 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)

84 the type of per-buffer values where appropriate.
85 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
86 predicate, which is how it's really used now. Adjust comment.

88 * buffer.c (buffer_slot_type_mismatch): Remove.
89 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
90 predicate. Adjust comment.

95 Use Qstringp for default-directory, buffer-file-name,
96 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
97 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
99 * data.c (store_symval_forwarding): Adjust to call the predicate.

117 * coding.c (coding_alloc_by_making_gap): Use it.
118 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
119 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
121 2013-01-08 Juri Linkov <juri@jurta.org>
123 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
124 of (supports :underline (:style wave)). (Bug#13000)

142 trailing dash is properly added.
144 2013-01-05 Eli Zaretskii <eliz@gnu.org>
146 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
147 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
148 digits for buffer positions, before misalignment starts.
149 Display "0" for integer "object" field.
150 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
151 Display the newline glyph more unambiguously.
153 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
155 * nsterm.m (ns_draw_underwave):
156 * w32term.c (w32_draw_underwave):
157 * xterm.c (x_draw_underwave): Make underwave look more triangular
158 and also degrade gracefully for small fonts. (Bug#13000)
160 * nsterm.m (ns_draw_text_decoration):
161 * w32term.c (x_draw_glyph_string):
162 * xterm.c (x_draw_glyph_string): Don't use previous underline
163 thickness and position if previous underline type is underwave.
165 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
167 * fileio.c (Ffile_acl): Undocument return format.

171 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
173 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>
176 * dired.c (file_name_completion):
177 * doc.c (get_doc_string):

182 * minibuf.c (Ftry_completion):
183 * term.c (tty_ins_del_lines):
184 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
185 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
187 2012-12-31 Eli Zaretskii <eliz@gnu.org>
189 * w32.c (unsetenv): Set up the string passed to _putenv
191 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
192 for the bug this caused.
194 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
196 * coding.c (Qmac): Now static.
198 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
200 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
201 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
202 handlebox_widget. Set toolbar_in_hbox to false/true, set
203 toolbar_is_packed to true.
204 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
205 (update_frame_tool_bar): Check toolbar_is_packed for packing.

209 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
210 Check toolbar_is_packed.
211 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
212 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
213 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
215 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
216 (xg_update_menubar): Update title only if
217 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
218 (xg_update_submenu): Skip tearoff only if
219 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
220 (xg_initialize): Initialize xg_detached_menus only if
221 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
223 * xterm.h (struct x_output): Surround handlebox_widget with
224 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
225 toolbar_in_hbox is bool.
227 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
229 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
230 (LIBS_GNUSTEP): Define.
231 (LIBES): Add $(LIBS_GNUSTEP).
232 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
234 2012-12-30 Eli Zaretskii <eliz@gnu.org>
236 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
237 continuation glyph on a TTY with an indication of an empty line.
240 2012-12-29 Eli Zaretskii <eliz@gnu.org>
242 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
243 file's SELinux context or ACLs successfully set, nil otherwise.
245 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
247 * w32proc.c (reader_thread): Avoid passing NULL handles to
248 SetEvent and WaitForSingleObject.
250 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
252 Port EXTERNALLY_VISIBLE to Clang 3.2.
253 * conf_post.h (__has_attribute): New macro.
254 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
256 2012-12-27 Glenn Morris <rgm@gnu.org>
258 * cygw32.c (Fcygwin_convert_file_name_to_windows)

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

278 * lisp.h (toplevel): Add two notices to the comment about
279 defining a new Lisp data type.
280 * print.c (print_object): If Lisp_Save_Value object's pointer
281 is the address of a memory area containing Lisp_Objects, try
283 * alloc.c (valid_lisp_object_p): Adjust comment.
285 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
287 * keyboard.c (record_asynch_buffer_change): Initialize an event
288 only if it's really needed.
289 * frame.h (enum output_method): Remove output_mac member since
290 it's a leftover from the deleted code.
291 * frame.c (Fframep): Adjust user here ...
292 * terminal.c (Fterminal_live_p): ... and here.
293 * coding.c (Qmac): Now here because it's only used to denote
294 end-of-line encoding type.
295 (syms_of_coding): DEFSYM it.
296 * frame.h (Qmac): Remove duplicated declaration.
298 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
300 * window.c (select_window_1): Now static, since it's used only here.
302 2012-12-25 Eli Zaretskii <eliz@gnu.org>
304 * window.c (window_body_cols): Subtract display margins from the
305 window body width on TTYs as well. See
306 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
307 for the original report.
309 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
311 * xdisp.c (redisplay_window): Remove inner local variable
312 because the outer shadowed one has the same meaning.
313 * xterm.h (struct x_output): Remove toolbar_detached member since it's
315 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
316 (xg_create_tool_bar): Adjust users.
318 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
320 * buffer.h (BUF_COMPACT): New macro to follow the common style.
321 * buffer.c (Fget_buffer_create): Use it to set compact field of
322 struct buffer_text to avoid accessing an uninitialized value
323 when compact_buffer is called for the first time.
324 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
325 (Fset_buffer_modified_p): Use buffer_window_count to check
326 whether the buffer is displayed in some window.
327 * xdisp.c (message_dolog): Likewise.
329 2012-12-23 Eli Zaretskii <eliz@gnu.org>
331 * w32.c (acl_set_file): If setting the file security descriptor
332 fails, and the new DACL is identical to the existing one, silently
333 return success. This fixes problems for users backing up their
334 own files without having the necessary privileges for setting
335 security descriptors.
337 * w32proc.c (reader_thread): Do not index fd_info[] with negative
339 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
340 after WaitForSingleObject returns normally. This expedites reader
341 thread shutdown when delete_child triggers it.
342 (reap_subprocess): More accurate commentary for why we call
343 delete_child only when cp->fd is negative.
345 * w32.c (sys_close): Do not call delete_child on a subprocess
346 whose handle is not yet closed. Instead, set its file descriptor
347 to a negative value, so that reap_subprocess will call
348 delete_child on that subprocess when its SIGCHLD arrives.
349 This avoids closing handles used for communications between sys_select
350 and reader_thread, which doesn't give sys_select a chance to
351 notice that the process exited and invoke the SIGCHLD handler for
354 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
356 * nsfns.m (Fns_do_applescript): Run event loop until script has
357 been executed (Bug#12969).
358 (ns_run_ascript): Chech as_script for nil, set to nil after
361 2012-12-22 Martin Rudalics <rudalics@gmx.at>

367 * w32term.c (w32fullscreen_hook): New function.
368 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
370 2012-12-21 Eli Zaretskii <eliz@gnu.org>
372 * fileio.c (Finsert_file_contents): Doc fix.
374 * w32proc.c (new_child, delete_child, find_child_pid): For a
375 subprocess, consider its slot being in use as long as its process
376 handle (procinfo.hProcess) is not NULL. This avoids reusing the
377 slot when a new process is started immediately after killing
378 another one, without waiting enough time for the first process to
379 be reaped and resources allocated for it be orderly freed.
381 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
383 2012-12-21 Chong Yidong <cyd@gnu.org>
385 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
387 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
389 2012-12-21 Eli Zaretskii <eliz@gnu.org>
391 * w32.c (get_name_and_id): Always pass NULL as the first argument
392 of lookup_account_sid. Avoids crashes with UNC file names that
393 refer to DFS domains, not to specific machine names. (Bug#12621)
394 Remove now unused argument FNAME; all callers changed.
395 (get_file_owner_and_group): Remove now unused argument FNAME; all
398 2012-12-21 Chong Yidong <cyd@gnu.org>
400 * editfns.c (Finsert_char): Since read-char-by-name now signals an
401 error for invalid chars, don't check for a nil return value.
403 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
405 Avoid calls to CHAR_TO_BYTE if byte position is known.
406 * editfns.c (make_buffer_string_both): Use move_gap_both.
407 (Fbuffer_string): Use make_buffer_string_both.
408 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
410 (buf_bytepos_to_charpos): Likewise.

412 * fileio.c (Finsert_file_contents): Use move_gap_both.
413 * search.c (Freplace_match): Likewise.
414 * process.c (process_send_region): Likewise. Use convenient
415 names for byte positions.
416 * lisp.h (charpos_to_bytepos): Remove prototype.
417 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
418 * insdel.c (move_gap): Likewise.

428 proper value of frame-local variables (bug#13225).
430 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
432 * textprop.c (set_text_properties_1): Do not allow NULL interval.
433 Rename 4th argument since it may be buffer or string. Adjust comment.
434 * intervals.c (graft_intervals_info_buffer): Find an interval here.
436 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
438 * coding.c (Fdetect_coding_region): Do not check start and end with
439 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
440 (code_convert_region): Likewise.
442 2012-12-18 Eli Zaretskii <eliz@gnu.org>
444 * w32.c (acl_get_file, acl_set_file): Run the file name through
445 map_w32_filename, and resolve any symlinks in the file name, like
447 (acl_set_file): Call revert_to_self, if any privileges were
450 2012-12-17 Juanma Barranquero <lekktu@gmail.com>

453 ($(BLD)/w32.$(O)): Update dependencies.
455 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
457 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
458 propagate redisplay's scrolling (if any) to the right window.
459 (redisplay_internal): Use ensure_selected_frame.
460 (display_mode_lines): Complete last fix.
461 * window.c (select_window_1): New func, extracted from select_window.
462 (select_window): Use it.
463 * window.h (select_window_1): Declare.
465 2012-12-17 Eli Zaretskii <eliz@gnu.org>
467 Emulate Posix ACL APIs on MS-Windows.
468 * w32.c: Include sddl.h and sys/acl.h.
469 (SDDL_REVISION_1): Define if not already defined.
470 (g_b_init_get_security_descriptor_dacl)
471 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)

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

503 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
505 2012-12-16 Romain Francoise <romain@orebokech.com>
507 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
508 (Fcopy_file): Change last arg to `preserve_extended_attributes'
509 and copy ACL entries of file in addition to SELinux context if set.
510 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
512 * Makefile.in (LIBACL_LIBS): New macro.
515 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
517 * fileio.c (internal_delete_file): Use bool for boolean.
519 2012-12-15 Eli Zaretskii <eliz@gnu.org>
521 Fix bug #13079 on MS-Windows with temp files not being deleted.
522 * w32.h (_child_process): New members input_file and
524 (register_child): First argument is now pid_t.
525 (record_infile, record_pending_deletion): New prototypes.
527 * w32proc.c (new_child): Initialize input_file and
528 pending_deletion members of the child.
529 (delete_child): Delete the child's temporary input file, if any,
530 that is pending deletion.
531 (register_child): First argument is now pid_t.
532 (record_infile, record_pending_deletion): New functions.
533 (reap_subprocess): Fix a typo in DebPrint string.
534 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
536 * fileio.c (internal_delete_file): Return an int again: non-zero
537 if delete-file succeeds, zero otherwise.
539 * lisp.h (internal_delete_file): Adjust prototype.
541 * callproc.c (Fcall_process): Don't overwrite infile with result
543 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
544 asynchronous subprocess, record the name of the input file name,
546 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
547 delete the file, record it as pending deletion when the subprocess
550 2012-12-14 Eli Zaretskii <eliz@gnu.org>
552 * editfns.c [HAVE_PWD_H]: Include grp.h.
554 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.

558 Fix permissions bugs with setgid directories etc. (Bug#13125)
559 * dired.c (Ffile_attributes): Return t as the 9th attribute,

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

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

630 2012-12-12 Daniel Colascione <dancol@dancol.org>
632 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
633 the dumped Emacs is not a sparse file, greatly improving Cygwin

638 * inotify.c (inotify_callback): Generate an Emacs event for every
639 incoming inotify event.
641 2012-12-11 Eli Zaretskii <eliz@gnu.org>
643 * xdisp.c (handle_face_prop): Fix logic of computing
644 it->start_of_box_run_p.
645 (append_space_for_newline): If the glyph row is R2L, reset the
646 iterator's end_of_box_run_p flag before prepending the space glyph.
647 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
648 iterator's start_of_box_run_p flag before prepending the stretch.

650 (append_stretch_glyph, append_glyphless_glyph): Reverse the
651 left_box_line_p and right_box_line_p flags of the glyph for R2L
652 glyph rows. (Bug#13011)

664 2012-12-11 Eli Zaretskii <eliz@gnu.org>
666 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
667 encoded_file_name, which is what it is.
669 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

702 (hinst): Remove unneeded extern declaration.
703 (_start): Remove initialization of above variables; remove
704 initialization of hinst, as cache_system_info now does that.

964 race condition that could cause Emacs to lose track of a child.
966 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
968 Avoid code duplication between prev_frame and next_frame.
969 * frame.c (candidate_frame): New function. Add comment.

975 fails, signal an error instead of continuing with an empty
977 Encode expanded temp file pattern before passing it to mkstemp or
980 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
981 Encode the file name before passing it to dostounix_filename, in
982 case it will downcase it (under w32-downcase-file-names).
985 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
987 Minor call-process cleanups.
988 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
989 at the same time as other platforms, to simplify analysis.

1013 Don't let call-process be a zombie factory (Bug#12980).
1014 Fixing this bug required some cleanup of the signal-handling code.
1015 As a side effect, this change also fixes a longstanding rare race
1016 condition whereby Emacs could mistakenly kill unrelated processes,
1017 and it fixes a bug where a second C-g does not kill a recalcitrant
1018 synchronous process in GNU/Linux and similar platforms.
1019 The patch should also fix the last vestiges of Bug#9488,
1020 a bug which has mostly been fixed on the trunk by other changes.
1021 * callproc.c, process.h (synch_process_alive, synch_process_death)
1022 (synch_process_termsig, sync_process_retcode):
1023 Remove. All uses removed, to simplify analysis and so that
1024 less consing is done inside critical sections.
1025 * callproc.c (call_process_exited): Remove. All uses replaced
1026 with !synch_process_pid.
1027 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1028 These take the role of what used to be in unwind-protect arg.
1030 (block_child_signal, unblock_child_signal):
1031 New functions, to avoid races that could kill innocent-victim processes.
1032 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1033 (call_process_kill): Record killed processes as deleted, so that
1034 zombies do not clutter up the system. Do this inside a critical
1035 section, to avoid a race that would allow the clutter.
1036 (call_process_cleanup): Fix code so that the second C-g works again
1037 on common platforms such as GNU/Linux.
1038 (Fcall_process): Create the child process in a critical section,
1039 to fix a race condition. If creating an asynchronous process,
1040 record it as deleted so that zombies do not clutter up the system.
1041 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1042 light of these changes. Omit unnecessary call to emacs_close
1043 before failure, as the unwind-protect code does that.
1044 * callproc.c (call_process_cleanup):
1045 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1046 * process.c (record_deleted_pid): New function, containing
1047 code refactored out of Fdelete_process.
1048 (Fdelete_process): Use it.
1049 (process_status_retrieved): Remove. All callers changed to use
1050 child_status_change.
1051 (record_child_status_change): Remove, folding its contents into ...
1052 (handle_child_signal): ... this signal handler. Now, this
1053 function is purely a handler for SIGCHLD, and is not called after
1054 a synchronous waitpid returns; the synchronous code is moved to
1055 wait_for_termination. There is no need to worry about reaping
1056 more than one child now.
1057 * sysdep.c (get_child_status, child_status_changed): New functions.
1058 (wait_for_termination): Now takes int * status and bool
1059 interruptible arguments, too. Do not record child status change;
1060 that's now the caller's responsibility. All callers changed.
1061 Reimplement in terms of get_child_status.
1062 (wait_for_termination_1, interruptible_wait_for_termination):
1063 Remove. All callers changed to use wait_for_termination.
1064 * syswait.h: Include <stdbool.h>, for bool.
1065 (record_child_status_change, interruptible_wait_for_termination):
1067 (record_deleted_pid, child_status_changed): New decls.
1068 (wait_for_termination): Adjust to API changes noted above.
1070 * bytecode.c, lisp.h (Qbytecode): Remove.
1071 No longer needed after 2012-11-20 interactive-p changes.
1073 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1075 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1076 the scroll margin, move point outside the margin. (Bug#13055)

1080 * gtkutil.c (my_log_handler): New function.
1081 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1083 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1085 * lisp.h (modify_region): Rename to...
1086 (modify_region_1): ...new prototype.
1087 * textprop.c (modify_region): Now static. Adjust users.
1088 * insdel.c (modify_region): Rename to...
1089 (modify_region_1): ...new function to work with current buffer.
1090 Adjust comment and users. Use true and false for booleans.
1092 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1094 * alloc.c (free_save_value): New function.
1095 (safe_alloca_unwind): Use it.
1096 * lisp.h (free_save_value): New prototype.
1097 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1099 (save_excursion_restore): Adjust to match saved data structure.
1100 Use free_save_value to offload some work from GC. Drop obsolete
1103 2012-12-03 Chong Yidong <cyd@gnu.org>
1105 * fileio.c (Vauto_save_list_file_name): Doc fix.
1107 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1109 * w32fns.c: Remove prototype of atof.
1110 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1112 (file_dialog_callback): Make it UINT_PTR.
1114 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1117 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1118 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1121 2012-12-03 Glenn Morris <rgm@gnu.org>
1123 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1125 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1127 Fix xpalloc confusion after memory is exhausted.
1128 * alloc.c (xpalloc): Comment fix.
1129 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1130 and signals an error, do not clear charset_table_size, as
1131 charset_table is still valid.
1132 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1134 Use execve to avoid need to munge environ (Bug#13054).
1135 * callproc.c (Fcall_process):
1136 * process.c (create_process):
1137 Don't save and restore environ; no longer needed.
1138 * callproc.c (child_setup):
1139 Use execve, not execvp, to preserve environ.
1141 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1143 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1145 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1147 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1148 display for sliced images (Bug#10500).
1150 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1152 2012-11-30 Juanma Barranquero <lekktu@gmail.com>

1155 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1157 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1159 * xdisp.c (window_outdated): Remove eassert since it hits
1160 some suspicious corner cases (see Bug#13007 and Bug#13012).

1164 (redisplay_internal, unwind_redisplay): Use it.
1165 (redisplay_internal): Move comment about buffer_shared...
1166 (buffer_shared_and_changed): ...near to its real use.
1168 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1170 * callproc.c (Fcall_process): Don't misreport vfork failure.
1172 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1174 * callproc.c (Fcall_process): Fix vfork portability problems.
1175 Do not assume that fd[0], count, filefd, and save_environ survive
1176 vfork. Fix bug whereby wrong errno value could be reported for
1177 pipe failure. Some minor cleanups, too, as follows. Move buf and
1178 bufsize to the context where they're needed. Change new_argv to
1179 be of type char **, as this is more convenient and avoids casts.
1180 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1181 Now local constants, not macros.
1183 2012-11-18 Kenichi Handa <handa@gnu.org>
1185 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1186 for the variable "f".

1190 * font.c (font_unparse_xlfd): Exclude special characters from the
1191 generating XLFD name.

1233 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1234 between bpos_covered and bpos_max. This fixes cursor display when
1235 several display strings follow each other.
1237 * .gdbinit (pgx): If the glyph's object is a string, display the
1238 pointer to string data, rather than the value of the string object
1239 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1241 * indent.c (Fvertical_motion): If the starting position is covered
1242 by a display string, return to one position before that, to avoid
1243 overshooting it inside move_it_to. (Bug#12930)

1264 of a literal "/". (Bug#12955)
1265 (gl-stamp): Invoke fc.exe directly, not through cmd.

1270 * dired.c: Assume HAVE_DIRENT_H.
1271 (NAMLEN): Remove, replacing with ...
1272 (dirent_namelen): New function. All uses changed. Use the GNU macro
1273 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1274 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1275 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1276 * makefile.w32-in (DIR_H): Remove. All uses replaced with

1280 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1281 Do not include <dirent.h>; no longer needed.

1286 * xftfont.c (xftfont_open): Remove duplicate assignment.
1288 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>

1291 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1292 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1293 * msdos.c (IT_frame_up_to_date): Use it here...
1294 * w32term.c (w32_frame_up_to_date): ...here...

1338 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1340 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1341 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1342 Define for the MSVC compiler.
1344 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.

1399 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1401 * w32select.c: Include w32common.h before w32term.h, so that
1402 windows.h gets included before w32term.h uses some of its
1403 features, see below.
1405 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1407 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:

1421 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1423 * w32proc.c (waitpid): Remove unused label get_result.

1446 (create_process): Assume FD_CLOEXEC.
1447 (create_process, create_pty): Assume O_NOCTTY.
1448 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1449 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1450 Omit if not DOS_NT, since F_GETFL is not defined there.
1451 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1452 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1454 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1455 lack it, since gnulib guarantees this.
1456 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1458 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1460 * w32.c (faccessat): Pretend that directories have the execute bit
1461 set. Emacs expects that, e.g., in files.el:cd-absolute.
1463 * w32proc.c (create_child): Don't clip the PID of the child
1464 process to fit into an Emacs integer, as this is no longer a
1466 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1467 reaping only the process specified by PID argument, if that is
1468 positive. Use PID instead of dead_child to know which process to
1469 reap. Wait for the child to die only if WNOHANG is not in
1471 (sys_select): Don't set dead_child.
1473 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1474 as it is no longer needed.
1476 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1478 (record_child_status_change): Remove the setting of
1479 record_at_most_one_child for the !WNOHANG case.
1481 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1483 Fix problems in ns port found by static checking.
1484 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1485 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1486 not to process group.
1487 (ns_select): Use emacs_write, not write, as that's more robust
1488 in the presence of signals.
1489 (fd_handler:): Check for read errors.
1491 2012-11-16 Glenn Morris <rgm@gnu.org>
1493 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1495 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1497 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1499 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1501 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1502 use the same value of thread handle.
1503 (start_timer_thread): If the timer thread exited (due to error),
1504 clean up by closing the two handles it used. Duplicate the caller
1505 thread's handle here, so it gets duplicated only once, when
1506 launching the timer thread. Set priority of the timer thread, not
1508 (getitimer): Don't duplicate the caller thread's handle here.
1511 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1513 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1516 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1518 Remove no-longer-used pty_max_bytes variable.
1519 * process.c (pty_max_bytes): Remove; unused.
1520 (send_process): Do not set it.
1522 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1524 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1525 Update dependencies.
1527 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1529 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1530 This follows up on the 2012-09-29 patch that removed indirection
1531 for the 'function' field. Reported by Sergey Vinokurov in
1532 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1534 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1536 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1537 different name, as the MS runtime does not have such a function,
1538 and probably never will.) All callers changed. Ignore DIRFD
1539 value if PATH is an absolute file name, to match Posix spec
1540 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1543 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1545 * xdisp.c (echo_area_display, redisplay_internal):
1546 Omit redundant check whether frame_garbaged is set.
1548 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1550 Use faccessat, not access, when checking file permissions (Bug#12632).
1551 This fixes a bug that has been present in Emacs since its creation.
1552 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1553 which must set some sort of record. (Torek's bug report was against
1554 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1555 same common flaw.) See Torek's Usenet posting
1556 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1557 Posted: Fri Apr 8 14:18:56 1983.
1558 * Makefile.in (LIB_EACCESS): New macro.
1560 * callproc.c (init_callproc):
1561 * charset.c (init_charset):
1562 * fileio.c (check_existing, check_executable, check_writable)
1564 * lread.c (openp, load_path_check):
1565 * process.c (allocate_pty):
1567 Use effective UID when checking permissions, not real UID.
1568 * callproc.c (init_callproc):
1569 * charset.c (init_charset):
1570 * lread.c (load_path_check, init_lread):
1571 Test whether directories are accessible, not merely whether they exist.
1572 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1573 * fileio.c (check_existing, check_executable, check_writable)
1575 Use symbolic names instead of integers for the flags, as they're
1577 (check_writable): New arg AMODE. All uses changed.
1578 Set errno on failure.
1579 (Ffile_readable_p): Use faccessat, not stat + open + close.
1580 (Ffile_writable_p): No need to call check_existing + check_writable.
1581 Just call check_writable and then look at errno. This saves a syscall.
1582 dir should never be nil; replace an unnecessary runtime check
1583 with an eassert. When checking the parent directory of a nonexistent
1584 file, check that the directory is searchable as well as writable, as
1585 we can't create files in unsearchable directories.
1586 (file_directory_p): New function, which uses 'stat' on most platforms
1587 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1588 (Ffile_directory_p, Fset_file_times): Use it.
1589 (file_accessible_directory_p): New function, which uses a single
1590 syscall for efficiency.
1591 (Ffile_accessible_directory_p): Use it.
1592 * xrdb.c (file_p): Use file_directory_p.
1593 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1594 * lread.c (openp): When opening a file, use fstat rather than
1595 stat, as that avoids a permissions race. When not opening a file,
1596 use file_directory_p rather than stat.
1597 (dir_warning): First arg is now a usage string, not a format.
1598 Use errno. All uses changed.
1599 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1600 that merely introduced a race.
1601 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1602 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1603 and similarly for the other O_* flags.
1604 * w32.c (sys_faccessat): Rename from sys_access and switch to
1605 faccessat's API. All uses changed.
1606 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1607 (magic_db): Rename from magic_file_p.
1608 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1609 char *, so that we don't have to test for file existence
1610 separately from opening the file for reading. This removes a race
1611 fixes a permission-checking problem, and simplifies the code.
1613 (file_p): Remove; no longer needed.
1615 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1617 Omit glyphs initialization at startup.
1618 * dispnew.c (glyphs_initialized_initially_p): Remove.
1619 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1620 (Fredraw_frame): Move actual code from here...
1621 (redraw_frame): ...to here. Add eassert. Adjust comment.
1622 (Fredraw_display): Use redraw_frame.
1623 * xdisp.c (clear_garbaged_frames): Likewise.
1625 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1627 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1628 passed to pint2str and pint2hrstr to be at most the size of the
1629 frame's decode_mode_spec_buffer. This avoids crashes with very
1630 large values of FIELD_WIDTH argument to decode_mode_spec.
1633 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1635 Fix a race with verify-visited-file-modtime (Bug#12863).
1636 Since at least 1991 Emacs has ignored an mtime difference of no
1637 more than one second, but my guess is that this was to work around
1638 file system bugs that were fixed long ago. Since the race is
1639 causing problems now, let's remove that code.
1640 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1641 whose time stamp is off by no more than a second. Insist that the
1642 file time stamps match exactly.
1644 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1646 * frame.h (struct frame): Convert external_tool_bar member to
1647 1-bit unsigned bitfield.
1648 * termhooks.h (struct terminal): Remove mouse_moved member since
1649 all users are long dead. Adjust comment on mouse_position_hook.
1651 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1653 Simplify by using FOR_EACH_FRAME here and there.
1654 * frame.c (next_frame, prev_frame, other_visible_frames)
1655 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1656 * w32term.c (x_window_to_scroll_bar): Likewise.
1657 * window.c (window_list): Likewise.
1658 * xdisp.c (x_consider_frame_title): Likewise.
1659 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1660 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1661 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1662 * xmenu.c (menubar_id_to_frame): Likewise.
1663 * xselect.c (frame_for_x_selection): Likewise.
1664 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1665 (x_window_to_menu_bar): Likewise.
1666 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1668 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1670 * data.c (Qdefalias_fset_function): Now static.
1672 Another tweak to vectorlike_header change.
1673 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1674 Remove, and replace all uses with ...
1675 (next_in_free_list, set_next_in_free_list):
1676 New functions, which respect C's aliasing rules better.
1678 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1680 * window.c (list4i): Rename from 'quad'. All uses changed.
1681 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1683 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1685 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1686 warning about mixing declarations and code in ISO C90.
1688 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1690 * window.c (Fsplit_window_internal): Set combination limit of
1691 new parent window to t iff Vwindow_combination_limit is t;
1692 fixing a regression introduced with the change from 2012-09-22.
1693 (Fset_window_combination_limit): Fix doc-string.
1695 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1697 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1698 amount when the scroll margins are too large. When scrolling
1699 backwards in the buffer, give up if cannot reach point or the
1700 scroll margin within a reasonable number of screen lines.
1701 Fixes point position in window under scroll-up/down-aggressively when
1702 point is positioned many lines beyond the window top/bottom.
1705 * ralloc.c (relinquish): If real_morecore fails to return memory
1706 to the system, don't crash; instead, leave the last heap
1707 unchanged and return. (Bug#12774)
1709 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1711 * lisp.h (AUTOLOADP): New macro.
1712 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1713 * data.c (Ffset): Remove special ad-advice-info handling.
1714 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1716 (Finteractive_form): Simplify.
1717 (Fquo): Don't insist on having at least 2 arguments.
1718 (Qdefalias_fset_function): New var.
1720 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1722 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
1724 * nsfont.m (Qcondensed, Qexpanded): New variables.
1725 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
1726 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
1728 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1730 Fix recently introduced crash on MS-Windows (Bug#12839).
1731 * w32term.h (struct scroll_bar): Use convenient header.
1732 (SCROLL_BAR_VEC_SIZE): Remove.
1733 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1735 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1737 Tweak last vectorlike_header change.
1738 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1739 vectorlike object on the free list. This is introduced to avoid
1740 some (but not all) pointer casting and aliasing problems, see
1741 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1742 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1744 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1746 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1748 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1749 been removed, so remove them here also.
1751 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1753 * doc.c (Fdocumentation): Handle new property
1754 dynamic-docstring-function to replace the old ad-advice-info.
1756 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1758 * fns.c (Qeql, hashtest_eq): Now static.
1760 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1762 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1763 * fns.c (hashfn_eq, hashfn_eql, sxhash):
1764 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
1765 * buffer.c (compare_overlays): Use XLI rather than XHASH.
1767 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
1769 Use same hash function for hashfn_profiler as for hash_string etc.
1770 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1771 * lisp.h (sxhash_combine): New inline function, with the contents
1772 of the old SXHASH_COMBINE.
1773 * profiler.c (hashfn_profiler): Use it, instead of having a
1774 special hash function containing a comparison that always yields 1.
1776 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1778 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1779 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1780 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1783 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1785 * image.c (xpm_make_color_table_h): Fix compiler error because
1786 make_hash_table changed.
1788 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1790 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1792 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1794 Use ad-hoc comparison function for the profiler's hash-tables.
1795 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1796 (make_log): Use them.
1797 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1798 call Fequal any more.

1807 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1808 (hash_lookup, hash_remove_from_table): Move assertion checking of
1809 hashfn result here. Check hash-equality before calling cmpfn.
1810 (Fmake_hash_table): Adjust call to make_hash_table.
1811 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.

1817 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
1819 2012-11-08 Eli Zaretskii <eliz@gnu.org>
1821 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
1822 value of w32-scroll-lock-modifier is neither nil nor one of the
1823 known key modifiers. (Bug#12806)
1825 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1827 Shrink struct vectorlike_header to the only size field.
1828 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1830 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
1831 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
1832 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
1833 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1834 information from the vector header. Adjust comment.
1835 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
1836 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
1838 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.

1844 (enum mem_type): Adjust comment.
1845 (NEXT_IN_FREE_LIST): New macro.
1846 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1847 (Fmake_bool_vector): Likewise.
1848 (struct large_vector): New type to represent allocation unit for
1849 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1850 (large_vectors): Change type to struct large_vector.
1851 (allocate_vector_from_block): Simplify.
1852 (PSEUDOVECTOR_NBYTES): Replace with...
1853 (vector_nbytes): ...new function. Adjust users.
1854 (sweep_vectors): Adjust processing of large vectors.
1855 (allocate_vectorlike): Likewise.
1856 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
1857 Add easserts. Adjust XSETPVECTYPESIZE usage.
1858 (allocate_buffer): Use BUFFER_PVEC_INIT.
1859 (live_vector_p): Adjust to match large vector.
1860 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1861 * buffer.h (struct buffer): Add next member.
1862 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1864 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
1865 * fns.c (internal_equal): Adjust to match enum pvec_type change.
1866 (copy_hash_table): Adjust to match vector header change.
1867 * lread.c (defsubr): Use XSETPVECTYPE.
1868 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
1869 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
1870 (xvecsize): New command.
1872 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1874 * keyboard.c (event_to_kboard): Do not dereference
1875 frame_or_window field of SELECTION_REQUEST_EVENT
1876 and SELECTION_CLEAR_EVENT events (Bug#12814).
1877 * xterm.h (struct selection_input_event): Adjust comment.
1879 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1881 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1882 such as Scroll Lock, if the respective keys are treated as
1883 function keys, not as modifiers. This avoids destroying non-ASCII
1884 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1886 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1888 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1890 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1892 Restore some duplicate definitions (Bug#12814).
1893 This undoes part of the 2012-11-03 changes. Some people build
1894 with plain -g rather than with -g3, and they need the duplicate
1895 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1896 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1897 Define as macros, as well as as enums or as constants.
1899 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1901 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1902 to keypad keys (Bug#12816).
1904 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1906 Minor adjustments of recently-changed frame functions.
1907 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1908 known to be a frame (we're in the FRAMEP branch).
1909 * lisp.h (Qframep): Remove decl. frame.h declares this.
1910 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1911 since they're meant for Lisp fixnum values.
1913 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1915 * window.c (Fwindow_combination_limit): Revert to the only
1916 required argument and adjust docstring as suggested in
1917 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1918 by Martin Rudalics <rudalics@gmx.at>.
1920 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1922 Widely used frame validity and checking functions.
1923 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
1924 * frame.c (decode_live_frame, decode_any_frame): New functions.
1925 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
1926 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
1927 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
1928 (Fframe_pointer_visible_p): Use decode_any_frame.
1929 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
1930 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
1931 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
1932 (Fframe_focus): Likewise. Allow zero number of arguments.
1934 (frame_buffer_list, frame_buffer_predicate): Remove.
1935 * lisp.h (frame_buffer_predicate): Remove prototype.
1936 * buffer.c (Fother_buffer): Use decode_any_frame.
1937 * xdisp.c (Ftool_bar_lines_needed): Likewise.
1938 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1939 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1940 (Fclose_font, Ffont_info): Use decode_live_frame.
1941 * fontset.c (check_fontset_name): Likewise.
1942 * terminal.c (Fframe_terminal): Likewise.
1943 * w32fns.c (check_x_frame): Likewise.
1944 * window.c (Fminibuffer_window, Fwindow_at)
1945 (Fcurrent_window_configuration): Likewise.
1946 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
1947 Likewise. Allow zero number of arguments. Adjust docstring.
1948 * dispnew.c (Fredraw_frame): Likewise.
1949 * xfaces.c (frame_or_selected_frame): Remove.
1950 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
1951 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
1952 (Fframe_face_alist): Use decode_live_frame.
1953 * xfns.c (check_x_frame): Likewise.
1955 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1957 * window.c (quad): New function.
1958 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
1959 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
1960 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
1961 (Fwindow_line_height): Use it.
1962 (Fwindow_fringes): Use list3.
1963 (Fwindow_scroll_bars): Use list4.
1964 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
1965 (Fwindow_combination_limit): Allow zero number of arguments.
1967 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1969 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1971 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1972 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1973 file descriptor 2 for standard error. (Bug#12805)
1975 2012-11-05 Chong Yidong <cyd@gnu.org>
1977 * process.c (wait_reading_process_output): Revert previous change.
1979 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1981 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1982 This removes code that has been obsolete since around 1990.
1983 * callproc.c (Fcall_process):
1985 * process.c (create_process):
1986 * term.c (dissociate_if_controlling_tty):
1987 Assume setsid exists.
1988 * callproc.c (child_setup): Assume setpgid exists and behaves as
1989 per POSIX.1-1988 or later.
1990 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1991 * emacs.c (shut_down_emacs):
1992 * sysdep.c (sys_suspend, init_foreground_group):
1993 Assume getpgrp behaves as per POSIX.1-1998 or later.
1994 * msdos.c (setpgrp): Remove.
1995 (tcgetpgrp, setpgid, setsid): New functions.
1996 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1997 * term.c (no_controlling_tty): Remove; unused.
1998 * w32proc.c (setpgrp): Remove.
1999 (setsid, tcgetpgrp): New functions.
2001 Simplify by assuming __fpending.
2002 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
2003 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
2004 Do not assume that __fpending's result fits in int.
2006 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
2008 Remove EMACS_OUTQSIZE+sleep hack.
2009 * dispnew.c (update_frame_1): Remove hack for terminals slower
2010 than 2400 bps, which throttled Emacs by having it sleep.
2011 This code hasn't worked since at least 2007, when the multi-tty stuff
2012 was added, and anyway those old terminals are long dead.
2013 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
2014 without the dispnew.c change, as dispnew.c doesn't include systty.h.
2016 Fix data-loss with --version (Bug#9574).
2017 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
2018 as we can't assume that emacs_strerror is initialized, and strerror
2019 is good enough here.
2020 (main): Invoke atexit earlier, to catch earlier instances of
2021 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
2023 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
2025 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
2026 (keyDown): Remap keypad keys to X11 virtual key codes.
2028 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2030 Fix data-loss with --batch (Bug#9574).
2031 * emacs.c: Include <close-stream.h>.
2032 (close_output_streams): New function.
2033 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2034 and handles errors appropriately.
2035 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2038 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2039 The symptom is a diagnostic "GLib-WARNING **: In call to
2040 g_spawn_sync(), exit status of a child process was requested but
2041 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2042 waitpid(), so exit status can't be returned." The diagnostic
2043 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2044 The real bug is a race condition between Emacs and glib: Emacs
2045 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2046 so that glib can't find it. Work around the bug by invoking
2047 waitpid only on subprocesses that Emacs itself creates.
2048 * process.c (create_process, record_child_status_change):
2049 Don't use special value -1 in pid field, as the caller now must
2050 know the pid rather than having the callee infer it.
2051 The inference was sometimes incorrect anyway, due to another race.
2052 (create_process): Set new 'alive' member if child is created.
2053 (process_status_retrieved): New function.
2054 (record_child_status_change): Use it.
2055 Accept negative 1st argument, which means to wait for the
2056 processes that Emacs already knows about. Move special-case code
2057 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2058 processes that have already been waited for, by testing and
2059 clearing new 'alive' member.
2060 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2061 now does this internally.
2062 (handle_child_signal): Let record_child_status_change do all
2063 the work, since we do not want to reap all exited child processes,
2064 only the child processes that Emacs itself created.
2065 * process.h (Lisp_Process): New boolean member 'alive'.
2067 Omit duplicate definitions no longer needed with gcc -g3.
2068 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2069 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2070 Define only as macros. There's no longer any need to also define
2071 these symbols as enums or as constants, since we now assume
2072 gcc -g3 when debugging.
2074 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2076 * lisp.mk: Adjust comments to the fact that term/internal is now
2077 loaded from loadup.el.
2079 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2080 (msdos_fatal_signal): New function.
2081 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2084 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2085 for GCC versions before 4.
2086 (emacs_raise): Define to call msdos_fatal_signal.
2088 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2089 iterator when starting in the middle of a display or overlay
2092 2012-11-03 Chong Yidong <cyd@gnu.org>
2094 * process.c (wait_reading_process_output): Clean up the last
2097 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2099 * process.c (wait_reading_process_output): Avoid a race condition
2100 with SIGIO delivery (Bug#11536).
2102 2012-11-03 Chong Yidong <cyd@gnu.org>
2104 * buffer.c (cursor_type): Untabify docstring.
2106 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2108 * frame.h (struct frame): Drop can_have_scroll_bars member
2109 which is meaningless for a long time. Adjust comments.
2110 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2111 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2113 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2115 * window.c (decode_next_window_args): Update window arg after
2116 calling decode_live_window and so fix crash reported at
2117 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2118 by Juanma Barranquero <lekktu@gmail.com>.
2119 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2120 * font.c (Ffont_at): Likewise.
2122 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2124 * widget.c (resize_cb): New function.
2125 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2126 (EmacsFrameResize): Check if all is up to date before changing frame
2129 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2131 Implement backtrace output for fatal errors on MS-Windows.
2132 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2133 (BACKTRACE_LIMIT_MAX): New macro.
2134 (w32_backtrace): New function.
2135 (emacs_abort): Use w32_backtrace when the user chooses not to
2136 attach a debugger. Update the text of the abort dialog.
2138 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2140 Window-related stuff cleanup here and there.
2141 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2142 Use decode_any_window.
2143 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2144 * xdisp.c (Fformat_mode_line): Likewise.
2145 * font.c (Ffont_at): Use decode_live_window.
2146 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2147 * window.c (decode_next_window_args): Likewise.
2148 (decode_any_window): Remove static.
2149 * window.h (decode_any_window): Add prototype.
2150 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2151 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2154 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2156 Remove pad from struct input_event.
2157 * termhooks.h (struct input_event): Remove padding field.
2159 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2160 member is never cons for a long time. Adjust comment.
2161 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2162 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2163 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2164 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2166 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2168 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2170 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2172 Fix crash when using Emacs as commit editor for git (Bug#12697).
2173 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2174 and it is configured in conf_post.h.
2175 (Fcall_process): Don't invoke both setsid and setpgid; the former
2176 is enough, if it exists.
2177 * callproc.c (Fcall_process, child_setup):
2178 * process.c (create_process): Use setpgid.
2179 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2181 * dispnew.c (init_display): Initialize the foreground group
2182 if we are running a tty display.
2183 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2184 * lisp.h (init_foreground_group): New decl.
2185 * sysdep.c (inherited_pgroup): New static var.
2186 (init_foreground_group, tcsetpgrp_without_stopping)
2187 (narrow_foreground_group, widen_foreground_group): New functions.
2188 (init_sys_modes): Narrow foreground group.
2189 (reset_sys_modes): Widen foreground group.
2191 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2193 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2195 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2197 * minibuf.c (read_minibuf): Restore current buffer since
2198 choose_minibuf_frame calling Fset_frame_selected_window may
2199 change it (Bug#12766).
2201 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2203 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2205 2012-10-30 Kenichi Handa <handa@gnu.org>
2207 * font.c (Ffont_at): If WINDOW is specified and it is not
2208 displaying the current buffer, signal an error.
2210 2012-10-29 Daniel Colascione <dancol@dancol.org>
2212 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2213 In preparation for fixing bug#12739, move these functions from
2216 * coding.h, coding.c: ... to here, and compile them only when
2217 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2218 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2220 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2222 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2223 (timer_loop, getitimer, setitimer): Use it instead of
2224 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2226 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2229 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2231 * nsterm.m (NO_APPDEFINED_DATA): New define.
2232 (last_appdefined_event_data): New variable
2233 (last_appdefined_event): Remove.
2234 (ns_select): Initialize t from last_appdefined_event_data instead
2235 of [last_appdefined_event data1].
2236 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2237 remove last_appdefined_event (Bug#12698).
2239 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2241 * frame.c (x_set_font): Catch internal error.
2243 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2245 Avoid overflow in w32 implementation of interval timers.
2246 When possible, for ITIMER_PROF count only times the main thread
2248 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2249 'volatile ULONGLONG' types. All the other data which was
2250 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2251 (GetThreadTimes_Proc): New typedef.
2252 (w32_get_timer_time): New function, returns a suitable time value
2254 (timer_loop): Enter critical section when accessing ULONGLONG
2255 values of the itimer_data struct, as these accesses are no longer
2256 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2257 Remove unused variable.
2258 (init_timers): Initialize s_pfn_Get_Thread_Times.
2259 (start_timer_thread): Don't assign itimer->caller_thread here.
2260 (getitimer): Assign itimer->caller_thread here.
2261 (setitimer): Always call getitimer to get the value of ticks_now.
2262 (sys_spawnve): Avoid compiler warning about format mismatch.
2264 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2266 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2267 mouse movement events if the menu bar is active. This avoids
2268 producing a busy "hour-glass" cursor by Windows if the mouse
2269 pointer is positioned over a tooltip shown for some menu item.
2271 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2273 Don't assume process IDs fit in int.
2274 * emacs.c (shut_down_emacs) [!DOS_NT]:
2275 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2276 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2277 Use pid_t, not int, to store process IDs, as 'int'
2278 is not wide enough on a few platforms (e.g., AIX and IRIX).
2280 2012-10-23 Kenichi Handa <handa@gnu.org>
2282 The following change is to make face-font-rescale-alist work
2283 correctly for non-ASCII fonts.
2285 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2286 (font_open_for_lface): Handle Vface_font_rescale_alist.
2288 2012-10-23 Chong Yidong <cyd@gnu.org>
2290 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2292 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
2294 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
2296 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2298 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2301 2012-10-21 Glenn Morris <rgm@gnu.org>
2303 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2305 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2307 Port to OpenBSD 5.1.
2308 * frame.c (Fmouse_position, Fmouse_pixel_position):
2309 * xdisp.c (produce_stretch_glyph):
2310 Declare local vars only when they're needed.
2311 This is clearer and avoids a warning on OpenBSD about unused vars.
2312 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2313 This is safer, and avoids OpenBSD warnings about unused vars.
2314 * keyboard.c (record_menu_key): Remove unnecessary decl.
2315 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2316 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2317 as our definition clashes with OpenBSD's.
2318 * xfaces.c (load_face_colors, check_lface_attrs)
2319 (get_lface_attributes_no_remap, get_lface_attributes)
2320 (lface_fully_specified_p, x_supports_face_attributes_p)
2321 (tty_supports_face_attributes_p, face_fontset, realize_face)
2322 (realize_x_face, realize_tty_face):
2323 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2324 merely Lisp_Object *. This is more informative and avoids
2325 a warning on OpenBSD about accessing beyond an object's size.
2327 2012-10-20 Chong Yidong <cyd@gnu.org>
2329 * lread.c (Fload): Doc fix (Bug#12592).
2331 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2333 * font.c (Ffont_at): Fix previous change.
2335 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2337 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.

2820 GUI facilities in a forked child. Also call syms_of_cygw32,
2821 syms_of_w32select in correct places.
2823 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2824 needs fork-then-exec for daemon launching.
2826 * font.h: Include frame.h.
2828 * image.c: Use the image library cache machinery only when we're
2829 compiling for native WINDOWSNT; Cygwin can use shared libraries
2830 like any other Unixlike system.
2832 * keyboard.c: Clarify a comment regarding the input loop.
2834 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2835 functions directly instead of trying to detect at runtime that our
2836 host operating system supports them. We make this change for two
2837 reasons: Cygwin lacks support for the multibyte character
2838 conversion functions used by the legacy menu code, and Cygwin
2839 never needs to rely on non-Unicode APIs.
2841 * unexw32.c (hinst): Declare extern.
2843 * w32.c: Change header order;
2844 (w32_strerror): Move to w32fns.c because we need it for
2845 non-WINDOWSNT builds.
2847 * w32.h: Add #error macro to make sure we don't include w32.h for
2848 Cygwin builds. Remove w32select declarations.
2850 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2851 w32fns.c. w32console.c is WINDOWSNT-only.
2853 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2854 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2856 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2857 (w32_major_version, w32_minor_version, w32_build_number)
2858 (os_subtype, sound_type): Define here
2859 (w32_defined_color): Make color parameter const for consistency
2860 with other _defined_color functions.
2861 (w32_createwindow): Unconditionally call w32_init_class instead of
2862 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2863 through the code is complex and unnecessary because class
2864 registration is practically free.
2865 (w32_name_of_message): New EMACSDEBUG-only function.
2866 (Fset_message_beep): Move here
2867 (Fx_open_connection): Require that the display name for Windows be
2868 "w32" for consistency, emacsclient disambiguation, and maybe, one
2869 day, multi-window-system support.
2870 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2871 Cygwin files for W32 GUI facilities, since these clearly don't
2872 expect Cygwin names.
2873 (_DebPrint): Define.
2874 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2875 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2876 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2877 (w32_last_error): Remove.
2879 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2881 * w32heap.c (syspage_mask): Declare here.
2882 (cache_system_info): Remove.
2884 * w32inevt.c (faked_key): Define globally, not statically.
2885 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2886 (w32_console_toggle_lock_key): Move to w32fns.c.
2888 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2890 * w32proc.c (_DebPrint): Move to w32fns.c.
2891 * w32select.c: Include string.h, stdio.h for Cygwin.
2892 * w32select.h: New File.
2894 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2896 (w32_message_fd): New variable. Under Cygwin, holds the file
2897 descriptor the system used to tell us about pending thread
2900 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2901 that prevented compilation under non-WINDOWSNT systems.
2903 (w32_initialize): Open /dev/windows and assign it to
2904 w32_message_fd. Provide w32 feature.
2906 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2907 (WM_EMACS_INPUT_READY): add.
2908 (prepend_msg, w32_message_fd): Declare globally.
2911 (keyboard_handle): Use only when WINDOWSNT.
2912 (notify_msg_ready): New function. Posts a message to the main
2913 thread's message queue under CYGWIN, which wakes up the main
2914 thread from select(2) by making the /dev/windows file descriptor
2915 ready. Under WINDOWSNT, it sets an event the same way the old
2918 (post, prepend_msg): Actually call notify_msg_ready instead of
2919 setting the input event directly.
2921 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2923 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2924 but it still has blocs in it, don't return it to the system,
2925 instead of aborting. (Bug#12402)
2927 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2929 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2931 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2932 MAC_OS_X_VERSION_10_6.
2933 (syms_of_nsterm): Remove comment about Panther and above for
2935 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
2936 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
2937 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2939 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2940 MAC_OS_X_VERSION_10_4.
2942 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2943 MAC_OS_X_VERSION_10_2.
2945 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2947 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2948 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2950 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2951 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2952 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2953 Remove ns_in_resize check.
2954 (ns_clear_frame_area): Remove resize handle code.
2956 * nsfns.m (ns_in_resize): Remove.
2957 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2958 Remove ns_in_resize check.
2960 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2962 Improve sys_siglist detection.
2963 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2964 defined as a macro, as is done in Solaris.
2965 (sys_siglist_entries): New macro.
2966 (save_strsignal): Use it.
2967 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2968 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2970 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2972 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2973 fullscreen/Fullscreen.
2975 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2976 tobar_height is new.
2978 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2979 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2980 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2981 (windowDidResize:): Check for correct window if old style fullscreen.
2982 Capitalize word in comment. Remove incorrect comment.
2983 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2984 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2985 error in drawing background.
2986 (toggleFullScreen:): Remove comment. Rearrange calls.
2987 Set toolbar values to zero, save old height in tobar_height.
2988 Restore tool bar height when leaving fullscreen.
2989 (canBecomeMainWindow): New function.
2991 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2993 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2995 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2997 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2999 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
3000 that time stamps of directories could also be changed.
3001 Don't request the too broad GENERIC_WRITE, only the more restrictive
3002 FILE_WRITE_ATTRIBUTES access rights.
3004 * fileio.c (Fset_file_times): Special-case ignoring errors for
3005 directories only on MSDOS, not on MS-Windows.
3007 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
3009 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
3011 2012-10-04 Eli Zaretskii <eliz@gnu.org>
3013 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
3014 see whether CreateFile failed.
3016 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
3018 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
3019 to avoid similar races.
3020 * keyboard.c (pending_signals): Now bool, not int.
3022 Port timers to OpenBSD, plus check for timer failures.
3023 OpenBSD problem reported by Han Boetes.
3024 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
3026 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3027 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3028 like OpenBSD, which has timer_settime but does not declare it.
3029 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3030 whether to use itimerspec-related primitives. All uses of
3031 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3033 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3035 * profiler.c (handle_profiler_signal): Fix a malloc race
3036 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3038 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3040 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3042 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3044 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3045 consistent with the change in return value of 'safe_strsignal'.
3047 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3049 Prefer plain 'static' to 'static inline' (Bug#12541).
3050 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3051 (bidi_set_sor_type, bidi_push_embedding_level)
3052 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3053 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

3056 (bidi_peek_at_next_level, bidi_set_paragraph_end)
3057 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3058 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3059 Now 'static', not 'static inline'.
3061 Count overruns when profiling; change units to ns.
3062 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3063 Give extra weight to samples after overruns, to attempt to count
3064 the time more accurately.
3065 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3066 the underlying primitives nominally do ns.
3067 (Fprofiler_cpu_start): Document the change. Mention that
3068 the sampling intervals are only approximate.
3070 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3072 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3074 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3075 case for the special 0 coding-system.
3077 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3078 (Fmake_overlay): Remove redundant tests.
3079 (fix_start_end_in_overlays): Remove redundant recentering.
3081 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3083 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3084 Update dependencies.
3086 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3088 Fix a malloc race condition involving strsignal.
3089 A signal can arrive in the middle of a malloc, and Emacs's signal
3090 handler can invoke strsignal, which can invoke malloc, which is
3091 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3092 Fix it by altering the signal handler so that it does not invoke
3094 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3095 * process.c (status_message): Use const pointer, in case strsignal
3096 is #defined to safe_strsignal.
3097 * sysdep.c (sys_siglist, init_signals): Always define and
3098 initialize a substitute sys_siglist if the system does not define
3099 one, even if HAVE_STRSIGNAL.
3100 (safe_strsignal): Rename from strsignal. Always define,
3101 using sys_siglist. Return a const pointer.
3102 * syssignal.h (safe_strsignal): New decl.
3103 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3105 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3107 * w32proc.c (timer_loop): Fix code that waits for timer
3108 expiration, to avoid high CPU usage.
3110 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3112 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3113 (sweep_weak_table): Remove redundant prototypes.
3115 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3117 * emacs.c: Move the inclusion of TERM_HEADER after including
3118 windows.h on WINDOWSNT. This avoids compilation problems with
3121 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3123 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3124 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3125 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3126 as the previous version used 'void *'.
3128 * ralloc.c (ROUNDUP): Fix last change.
3129 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3132 * w32proc.c <disable_itimers>: New static flag.
3133 (init_timers): Initialize it to zero, after creating the critical
3134 sections used by the timer threads.
3135 (term_timers): Set to 1 before deleting the critical sections.
3136 (getitimer, setitimer): If disable_itimers is non-zero, return an
3137 error indication without doing anything. Reported by Fabrice
3138 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3139 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3141 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3144 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3145 term_ntproc after all the other bookkeeping, to get timers working
3146 as long as possible.
3148 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3150 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3151 Suggested by Juri Linkov in
3152 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3154 Prefer plain 'static' to 'static inline' (Bug#12541).
3155 With static functions, modern compilers inline pretty well by
3156 themselves; advice from programmers often hurts as much as it helps.
3157 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3158 this change shrinks the text size of the Emacs executable by 1.1%
3159 without affecting CPU significantly in my benchmark.
3160 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
3161 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

3235 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
3236 Now 'static', not 'static inline'.
3239 (bidi_copy_it): Do the whole copy with a single memcpy.
3240 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3242 Revert the FOLLOW-SYMLINKS change for file-attributes.
3243 Doing it right would require several changes to Tramp, and there's
3244 not enough time to get that tested before the freeze today.
3245 * dired.c (directory_files_internal, Ffile_attributes):
3248 * frame.c (x_report_frame_params): Port better to wider ints.
3249 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3250 or that pointers can be printed in 15 decimal digits.
3251 Avoid GCC warnings if EMACS_UINT is wider than a pointer.
3253 2012-09-30 Fabrice Popineau <fabrice.popineau@supelec.fr>
3255 Support x64 build on MS-Windows.
3256 * w32term.h (SCROLL_BAR_PACK, SCROLL_BAR_UNPACK): Define for x64.

3453 (handle_profiler_signal): Rename from sigprof_handler_1,
3454 for consistency with other handlers. Do not check whether
3455 cpu_log is a hash-table if garbage collecting, since it

3458 for consistency with other handlers.
3459 (setup_cpu_timer): New function, with much of what used to be in

3461 Prefer timer_settime if available, and prefer
3462 thread cputime clocks, then process cputime clocks, then
3463 monotonic clocks, to the old realtime clock. Use make_timeval
3464 to round more-correctly when falling back to setitimer.
3465 (Fprofiler_cpu_start): Use it.
3466 (Fprofiler_cpu_stop): Prefer timer_settime if available.

3714 * gtkutil.c (xg_change_toolbar_position):
3717 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3719 * makefile.w32-in (BLOCKINPUT_H): Remove.

3736 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3738 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3739 fatal_error_backtrace.
3741 * w32proc.c (sys_kill): Undo last change: don't do anything when
3742 invoked to deliver SIGABRT to our own process. This is now
3743 handled by emacs_raise.
3745 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3747 * w32term.c (w32_read_socket): Remove leftover reference to
3748 interrupt_input_pending.
3750 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3752 Do not use SA_NODEFER.
3753 Problem reported by Dani Moncayo in
3754 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3756 * sysdep.c (emacs_abort): Do not reset signal handler.
3757 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3758 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3759 wanted even on POSIXish hosts, and it doesn't work on Windows.
3761 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3763 * xterm.c (x_term_init): Call fixup_locale before and after calling
3764 gtk_init (Bug#12392).
3766 2012-09-23 Chong Yidong <cyd@gnu.org>
3768 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3769 Vdynamic_library_alist.
3771 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3772 (Fgnutls_available_p): Caller changed.
3774 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3775 (Flibxml_parse_xml_region): Likewise.
3777 * dispextern.h (struct image_type): Remove arg from init function.
3779 * image.c (Finit_image_library, lookup_image_type)
3780 (define_image_type): Remove now-unneeded second arg.
3781 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3782 (init_tiff_functions, init_gif_functions, init_svg_functions):
3783 Arglist and w32_delayed_load calling convention changed.
3784 (gs_type): Remove init_gs_functions; there is no such function.
3785 (valid_image_p, make_image): Fix caller to lookup_image_type.
3787 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3789 Simplify and avoid signal-handling races (Bug#12471).
3791 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3792 Avoid recursive loop if there's a fatal error in the function itself.
3793 * atimer.c (pending_atimers):
3794 * blockinput.h: Don't include "atimer.h"; no longer needed.
3795 (interrupt_input_pending): Remove. All uses removed.
3796 pending_signals now counts both atimers and ordinary interrupts.
3797 This is less racy than having three separate pending-signal flags.
3798 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3800 Rename from their upper-case counterparts BLOCK_INPUT,
3801 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3802 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3803 This makes it easier to access volatile variables more accurately.
3804 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3805 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3806 that's more reliable if the code is buggy and sets
3807 interrupt_input_blocked to a negative value. All uses changed.
3808 * atimer.c (deliver_alarm_signal):
3809 Remove. No need to deliver this to the parent; any thread can
3810 handle this signal now. All uses replaced by underlying handler.
3811 * atimer.c (turn_on_atimers):
3812 * dispnew.c (handle_window_change_signal):
3813 * emacs.c (handle_danger_signal):
3814 * keyboard.c (kbd_buffer_get_event):
3815 Don't reestablish signal handler; not needed with sigaction.
3816 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3818 Rework to avoid unnecessary accesses to volatile variables.
3819 (UNBLOCK_INPUT_TO): Now a function.
3820 (totally_unblock_input, unblock_input): New decls.
3821 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3822 (init_data): Remove. Necessary stuff now done in init_signal.
3823 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3824 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3825 (fatal_error_code): Remove; no longer needed.
3826 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3827 it doesn't always backtrace. All uses changed. No need to reset
3828 signal to default, since sigaction and/or die does that for us now.
3829 Use emacs_raise (FOO), not kill (getpid (), FOO).
3830 (main): Check more-accurately whether we're dumping.
3831 Move fatal-error setup to sysdep.c
3832 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3833 * gtkutil.c (xg_get_file_name, xg_get_font):
3834 Remove no-longer-needed signal-mask manipulation.
3835 * keyboard.c, process.c (POLL_FOR_INPUT):
3836 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3837 * keyboard.c (read_avail_input): Remove.
3838 All uses replaced by gobble_input.
3839 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3840 (kbd_buffer_store_event_hold, gobble_input):
3841 (record_asynch_buffer_change) [USABLE_SIGIO]:
3842 (store_user_signal_events):
3843 No need to mess with signal mask.
3844 (gobble_input): If blocking input and there are terminals, simply
3845 set pending_signals to 1 and return. All hooks changed to not
3846 worry about whether input is blocked.
3847 (process_pending_signals): Clear pending_signals before processing
3848 them, in case a signal comes in while we're processing.
3849 By convention callers now test pending_signals before calling us.
3850 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3851 New functions, to support changes to blockinput.h.
3852 (handle_input_available_signal): Now extern.
3853 (reinvoke_input_signal): Remove. All uses replaced by
3855 (quit_count): Now volatile, since a signal handler uses it.
3856 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3857 All callers changed. Block SIGINT only if not already blocked.
3858 Clear sigmask reliably, even if Fsignal returns, which it can.
3859 Omit unnecessary accesses to volatile var.
3860 (quit_throw_to_read_char): No need to restore sigmask.
3861 * keyboard.c (gobble_input, handle_user_signal):
3862 * process.c (wait_reading_process_output):
3863 Call signal-handling code rather than killing ourselves.
3864 * lisp.h: Include <float.h>, for...
3865 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3866 (pending_signals): Now volatile.
3867 (syms_of_data): Now const if IEEE floating point.
3868 (handle_input_available_signal) [USABLE_SIGIO]:
3869 (terminate_due_to_signal, record_child_status_change): New decls.
3870 * process.c (create_process): Avoid disaster if memory is exhausted
3871 while we're processing a vfork, by tightening the critical section
3873 (send_process_frame, process_sent_to, handle_pipe_signal)
3874 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3876 (send_process): No need for setjmp/longjmp any more, since the
3877 SIGPIPE stuff is now gone. Instead, report an error if errno
3879 (record_child_status_change): Now extern. PID and W are now args.
3880 Return void, not bool. All callers changed.
3881 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3882 Remove. All uses removed. This bug should be fixed now in a
3884 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3885 and record the child status change directly. This avoids the
3886 need to futz with the signal mask.
3887 (process_fatal_action): Move here from emacs.c.
3888 (emacs_sigaction_flags): New function, containing
3889 much of what used to be in emacs_sigaction_init.
3890 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3891 caught by emacs, to make races less likely.
3892 (deliver_process_signal): Rename from handle_on_main_thread.
3894 (BACKTRACE_LIMIT_MAX): Now at top level.
3895 (thread_backtrace_buffer, threadback_backtrace_pointers):
3897 (deliver_thread_signal, deliver_fatal_thread_signal):
3898 New functions, for more-accurate delivery of thread-specific signals.
3899 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3900 (deliver_arith_signal): Handle in this thread, not
3901 in the main thread, since it's triggered by this thread.
3902 (maybe_fatal_sig): New function.
3903 (init_signals): New arg DUMPING so that we can be more accurate
3904 about whether we're dumping. Caller changed.
3905 Treat thread-specific signals differently from process-general signals.
3906 Block all signals while handling fatal error; that's safer.
3907 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3909 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3910 Ignore SIGPIPE unless batch.
3911 (emacs_backtrace): Output backtrace for the appropriate thread,
3912 which is not necessarily the main thread.
3913 * syssignal.h: Include <stdbool.h>.
3914 (emacs_raise): New macro.
3915 * xterm.c (x_connection_signal): Remove; no longer needed
3916 now that we use sigaction.
3917 (x_connection_closed): No need to mess with sigmask now.
3918 (x_initialize): No need to reset SIGPIPE handler here, since
3919 init_signals does this for us now.
3921 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3923 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3924 background rect may be larger (Bug#12245).
3926 2012-09-23 Chong Yidong <cyd@gnu.org>
3928 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3930 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3932 * .gdbinit: Just stop at fatal_error_backtrace.
3933 See Stefan Monnier's request in
3934 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3935 Remove no-longer-used query of system type.
3937 2012-09-22 Chong Yidong <cyd@gnu.org>
3939 * search.c (Freplace_match): Doc fix (Bug#12325).
3941 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3943 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3944 (Fline_end_position): Doc fix.
3946 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3948 2012-09-22 Chong Yidong <cyd@gnu.org>
3950 * dispextern.h (struct image_type): Add new slot, storing a type
3951 initialization function.
3953 * image.c (define_image_type): Call the image initializer function
3954 if it is defined. Arguments and return value changed.
3955 (valid_image_p, make_image): Callers changed.
3956 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3957 (gif_type, imagemagick_type, svg_type, gs_type):
3958 Add initialization functions.
3959 (Finit_image_library): Call lookup_image_type.
3960 (CHECK_LIB_AVAILABLE): Macro deleted.
3961 (lookup_image_type): Call define_image_type here, rather than via
3962 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3963 (syms_of_image): Move define_image_type calls for xbm_type and
3964 pbm_type to lookup_image_type.
3966 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3968 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3969 'idle_timers' from here ...
3970 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3971 lists, to avoid infloops when the timer does something stupid,
3972 like reinvoke itself with the same or smaller time-out.
3975 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3977 * window.c (Fsplit_window_internal): Handle only Qt value of
3978 Vwindow_combination_limit separately.
3979 (Qtemp_buffer_resize): New symbol.
3980 (Vwindow_combination_limit): New default value.
3983 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3985 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3986 the new overlay string. (Bug#10159)
3988 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3990 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3991 or that fprintf is async-signal-safe. POSIX doesn't require
3994 2012-09-22 Chong Yidong <cyd@gnu.org>
3996 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3999 2012-09-22 Kenichi Handa <handa@gnu.org>
4001 * composite.c (composition_reseat_it): Handle the case that a
4002 grapheme cluster is not covered by a single font (Bug#12352).
4004 2012-09-21 Chong Yidong <cyd@gnu.org>
4006 * image.c (define_image_type): Avoid adding duplicate types to
4007 image_types (Bug#12463). Suggested by Jörg Walter.
4009 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4011 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
4012 (print_load_command_name): Add case LC_DATA_IN_CODE.
4013 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
4015 2012-09-21 Glenn Morris <rgm@gnu.org>
4017 * eval.c (Frun_hook_with_args_until_success)
4018 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
4020 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
4022 * fileio.c (Ffile_selinux_context): Only call freecon when
4023 lgetfilecon succeeded.
4024 (Fset_file_selinux_context): Likewise. (Bug#12444)
4026 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4028 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4029 reordering, locate the cursor by calling set_cursor_from_row; if
4030 that fails, clear the desired glyph matrix before returning a
4031 failure indication to the caller. Fixes leaving garbled display
4032 when fast scrolling with a down-key. (Bug#12403)
4033 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4034 scrolling through multibyte text.
4036 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4038 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4039 calling mark_vectorlike since that's the one that marks the window.
4040 (mark_discard_killed_buffers): Mark the final cdr.
4041 * window.h (struct window): Move prev/next_buffers to the
4042 non-standard fields.
4043 * window.c (make_window): Initialize prev/next_buffers manually.
4045 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4047 Omit unused arg EXPECTED from socket hooks.
4048 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4049 * nsterm.m (ns_term_init):
4050 * termhooks.h (struct terminal.read_socket_hook):
4051 * w32inevt.c (w32_console_read_socket):
4052 * w32term.c (w32_read_socket):
4053 * xterm.c (XTread_socket):
4054 Omit unused arg EXPECTED. All callers changed.
4055 (store_user_signal_events): Return void, not int, since callers no
4056 longer care about the return value. All uses changed.
4058 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4060 * w32gui.h (XParseGeometry): Do not declare.
4062 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4064 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4065 Ignore 'expected'. See Eli Zaretskii in
4066 <http://bugs.gnu.org/12471#8> (last line).
4068 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4069 (XParseGeometry): Now static. Substitute extremal values for
4070 values that are out of range.
4072 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4074 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4076 * nsfns.m (XParseGeometry): Remove.
4077 (Fx_create_frame): Call x_set_offset to correctly interpret
4078 top_pos in geometry.
4080 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4081 (Fx_parse_geometry): If there is a space in string, call
4082 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4084 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4086 * search.c (scan_buffer): Use character positions in calls to
4087 region_cache_forward and region_cache_backward, not byte
4088 positions. (Bug#12196)
4090 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4091 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4093 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4094 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4095 emacs_blocked_malloc, now deleted.
4097 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4099 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4100 The workaround was for improving performance on Solaris 2.4, but
4101 is getting in the way now. Emacs will still work if someone is
4102 still running Solaris 2.4 in a museum somewhere; Sun dropped
4103 support for Solaris 2.4 in 2003.
4104 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4105 * process.c (create_process) [HAVE_WORKING_VFORK]:
4106 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4107 since Emacs no longer uses vfork on that platform.
4109 2012-09-17 Glenn Morris <rgm@gnu.org>
4111 * emacs.c: Use COPYRIGHT.
4113 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4115 Remove configure's --without-sync-input option (Bug#12450).
4116 When auditing signal-handling in preparation for cleaning it up,
4117 I found that SYNC_INPUT has race conditions and would be a real
4118 pain to fix. Since it's an undocumented and deprecated
4119 configure-time option, now seems like a good time to remove it.
4120 Also see <http://bugs.gnu.org/11080#16>.
4121 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4122 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4123 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4124 (malloc_hysteresis):
4125 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4126 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4127 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4128 (dont_register_blocks, bytes_used_when_reconsidered)
4129 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4130 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4131 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4132 Remove. All uses removed.
4133 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4134 implementation, one that depends on whether the new macro
4135 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4137 * atimer.c (run_timers, handle_alarm_signal):
4138 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4139 (handle_async_input, process_pending_signals)
4140 (handle_input_available_signal, init_keyboard):
4141 * nsterm.m (ns_read_socket):
4142 * process.c (wait_reading_process_output):
4143 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4144 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4146 * xterm.c (XTread_socket):
4148 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4149 * eval.c (handling_signal): Remove. All uses removed.
4150 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4151 All uses replaced with the SYNC_INPUT version.
4152 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4154 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4157 * font.c (Ffont_shape_gstring): Remove unused local.
4159 2012-09-16 Glenn Morris <rgm@gnu.org>
4161 * Makefile.in (clean): No longer run nextstep's clean.
4163 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4165 (ns-app): Move here from ns.mk, and simplify.
4166 (clean): Simplify nextstep entry.
4167 * ns.mk: Remove file.
4169 2012-09-17 Kenichi Handa <handa@gnu.org>
4171 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4172 not covert the last few charactes.
4174 2012-09-16 Kenichi Handa <handa@gnu.org>
4176 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4177 here, but just check the validity of glyphs in the glyph-string.
4179 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4181 * window.c (Fwindow_parameter, Fset_window_parameter):
4182 Accept any window as argument (Bug#12452).
4184 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4186 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4187 to ns_term_init to avoid memory leak.
4189 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4190 explicit retain/release.
4191 (ns_term_init): Only allow one display. Initialize outerpool and
4194 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4196 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4197 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4198 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4199 the Microsoft problem in a different way, by altering ../nt/config.nt.
4201 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4216 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4217 by lisp.h. This completes removal of setjmp.h inclusion
4218 erroneously announced in the previous commit. (Bug#12446)
4220 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4223 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4224 not defined as a macro. The latter happens on MS-Windows.
4227 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4229 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4230 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4231 Some instances of '#include <setjmp.h>' removed, if the
4232 only reason for the instance was because "lisp.h" was included.
4233 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4234 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4235 and _longjmp with the new symbols. Emacs already uses _setjmp if
4236 available, so this change affects only POSIXish hosts that have
4237 sigsetjmp but not _setjmp, such as some versions of Solaris and
4238 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4239 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4240 (png_load_body) [HAVE_PNG]:
4241 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4242 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4243 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4244 since PNG requires jmp_buf. This is the only exception to the
4245 general rule that we now use sys_setjmp and sys_longjmp.
4246 This exception is OK since this code does not change the signal
4247 mask or longjmp out of a signal handler.
4249 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4251 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4252 Include "syssignal.h", for 'main_thread'.
4254 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4256 Avoid out-of-range marker position (Bug#12426).
4257 * insdel.c (replace_range, replace_range_2):
4258 Adjust markers before overlays, as suggested by comments.
4259 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4260 Remove redundant check before calling offset_intervals.
4262 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4264 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4265 current buffer (Bug#12387).
4267 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4269 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4271 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4273 Use a more backwards-compatible timer format (Bug#12430).
4274 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4275 vector element, not from the 4th, since PSECS is now at the end.
4276 (Fcurrent_idle_time): Doc fix.
4278 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4280 Function to mark objects and remove killed buffers at once.
4281 * alloc.c (discard_killed_buffers): Rename to ...
4282 (mark_discard_killed buffers) ... new name. Add marking
4283 of remaining objects. Fix comment. Adjust users.
4284 (mark_object): Do not touch frame buffer lists here.
4285 * frame.c (delete_frame): Reset frame buffer lists here.
4287 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4289 Better workaround for GNOME bug when --enable-gcc-warnings.
4290 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4291 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4292 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4294 Simplify SIGIO usage (Bug#12408).
4295 The code that dealt with SIGIO was crufty and confusing, e.g., it
4296 played tricks like "#undef SIGIO" but these tricks were not used
4297 consistently. Simplify mostly by not #undeffing standard symbols,
4298 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4299 or not as we please) rather than "defined SIGIO" (standard symbol
4300 that we probably shouldn't #undef).
4301 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4302 Modules that need it can include it.
4303 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4304 * dispextern.h (ignore_sigio): New decl.
4305 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4306 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4307 * emacs.c (shut_down_emacs):
4308 * keyboard.c (kbd_buffer_store_event_hold):
4309 Use ignore_sigio rather than invoking 'signal' directly.
4310 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4312 (FIONREAD, SIGIO): Do not #undef.
4313 (tty_read_avail_input): Use #error rather than a syntax error.
4314 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4315 for I_PIPE, used by SETUP_SLAVE_PTY.
4316 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4317 * sysdep.c (croak): Remove; no longer needed. This bit of
4318 temporary code, with Fred N. Fish's comment that it's temporary,
4319 has been in Emacs since at least 1992!
4320 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4321 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4322 * syssignal.h (croak): Remove decl.
4323 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4324 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4325 now that we're termios-only.
4326 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4327 * term.c (dissociate_if_controlling_tty): Use #error rather than
4330 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4331 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4332 to work around GNOME bug 683906.
4333 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4334 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4335 This works around GCC bug 54561.
4337 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4339 More fixes for 'volatile' and setjmp/longjmp.
4340 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4341 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4342 (png_load_body) [HAVE_PNG]:
4343 (jpeg_load_body) [HAVE_JPEG]:
4344 New function, with most of the old parent function's body.
4345 (png_load) [HAVE_PNG]:
4346 (jpeg_load) [HAVE_JPEG]:
4347 Invoke the new function, to avoid longjmp munging our locals.
4348 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4349 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4350 longjmp is passed 2, as the C standard doesn't guarantee this.
4351 Instead, store the failure code into mgr->failure_code.
4353 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4355 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4356 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4357 (syms_of_keyboard): Remove support for unread-command-char.
4359 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4361 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4362 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4363 violation. (Bug#12426)
4365 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4367 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4369 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4371 * eval.c: Add `inhibit-debugger'.
4372 (Qinhibit_debugger): New symbol.
4373 (call_debugger): Bind it instead of Qdebug_on_error.
4374 (maybe_call_debugger): Test Vinhibit_debugger.
4375 (syms_of_eval): Define inhibit-debugger.
4376 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4377 (syms_of_xdisp): Remove inhibit-debug-on-message.
4379 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4381 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4382 If a nonvolatile local variable is written before a _longjmp to
4383 the frame containing the variable, and is read after the _longjmp,
4384 the value read is indeterminate. Some local variables of type
4385 'struct handler' and 'struct catchtag' are used in this way, so
4386 mark each of their slots as volatile if the slot can be set before
4387 _longjmp and read afterwards.
4388 * lisp.h (struct handler): var and chosen_clause are now volatile.
4389 (struct catchtag): val, next, and pdlcount are now volatile.
4391 * bidi.c (bidi_push_it, bidi_pop_it):
4392 * fns.c (copy_hash_table):
4393 * image.c (define_image_type):
4394 * keyboard.c (kbd_buffer_store_event_hold):
4395 * process.c (Fprocess_send_eof):
4396 * xfaces.c (x_create_gc) [HAVE_NS]:
4397 * xgselect.c (xg_select):
4398 Prefer assignment to memcpy when either will do.
4400 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4401 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4402 time an item is removed. No need to mark this function 'inline';
4403 the compiler knows better than we do.
4405 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4407 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4408 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4409 to change_frame_size (Bug#12388).
4410 (windowDidResize:): Pass YES to updateFrameSize.
4412 * nsterm.h: Add delay parameter to updateFrameSize.
4414 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4416 Discard killed buffers from deleted window and frame objects.
4417 This reduces an amount of references to killed buffers and
4418 helps GC to reclaim them faster.
4419 * alloc.c (discard_killed_buffers): New function.
4420 (mark_object): Use it for deleted windows and frames.
4421 (mark_object): If symbol's value is set up for a killed buffer
4422 or deleted frame, restore its global binding.
4423 * data.c (swap_in_global_binding): Add GC notice.
4424 (swap_in_symval_forwarding): Use convenient set_blv_where.
4425 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4426 * window.h: ... to here.
4428 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4430 Convenient macro to check whether the buffer is live.
4431 * buffer.h (BUFFER_LIVE_P): New macro.
4432 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4433 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4435 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4437 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4438 composition cases (Bug#12364).
4440 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4441 overhang of succeeding glyphs overlapping box cursor.
4443 * w32term.c (x_draw_glyph_string): Likewise.
4445 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4447 Simplify, document, and port floating-point (Bug#12381).
4448 The porting part of this patch fixes bugs on non-IEEE platforms
4449 with frexp, ldexp, logb.
4450 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4452 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4453 support, by removing commented-out code and briefly listing the
4454 C89 functions excluded. The commented-out stuff was confusing
4455 maintenance, e.g., we thought we needed cbrt but it was commented out.
4456 (logb): Remove decl; no longer needed.
4457 (isfinite): New macro, if not already supplied.
4458 (isnan): Don't replace any existing macro.
4459 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4460 are present on all C89 platforms.
4461 (Ffrexp): Do not special-case zero, as frexp does the right thing
4463 (Flogb): Do not use logb, as it doesn't have the desired meaning
4464 on hosts that use non-base-2 floating point. Instead, stick with
4465 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4466 frexp, to avoid getting an unspecified result.
4468 * xdisp.c (Qinhibit_debug_on_message): Now static.
4470 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4472 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4473 NSBezierPath (Bug#12131).
4475 2012-09-10 Chong Yidong <cyd@gnu.org>
4477 * fns.c (Fdelq, Fdelete): Doc fix.
4479 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4481 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4482 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4484 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4486 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4487 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4490 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4492 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4493 left fringe if the window has a left margin. This avoids leaving
4494 traces of the cursor because its leftmost pixel is not drawn over.
4496 * dispnew.c (update_window_line): When the left margin area of a
4497 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4498 that screen line. (Bug#12277)
4500 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4502 Assume C89 or later for math functions (Bug#12381).
4503 This simplifies the code, and makes it a bit smaller and faster,
4504 and (most important) makes it easier to clean up signal handling
4505 since we can stop worring about floating-point exceptions in
4506 library code. That was a problem before C89, but the problem
4507 went away many years ago on all practical Emacs targets.
4508 * data.c, image.c, lread.c, print.c:
4509 Don't include <math.h>; no longer needed.
4510 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4511 might be autoconfigured, as that never happens.
4513 * doprnt.c (DBL_MAX_10_EXP):
4514 * print.c (DBL_DIG):
4515 Remove. C89 or later always defines these.
4516 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4517 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4518 (arith_error, domain_error, domain_error2):
4519 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4520 no longer needed -- we simply return what C returns. All uses removed.
4521 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4523 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4524 Remove. All uses expanded, as these macros are no longer used
4525 more than once and are now more trouble than they're worth.
4526 (Ftan): Use tan, not sin / cos.
4527 (Flogb): Assume C89 frexp.
4528 (fmod_float): Assume C89 fmod.
4529 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4530 (init_floatfns): Remove. All uses removed.
4532 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4534 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4535 compositeToPoint for OSX < 10.6 (Bug#12390).
4537 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4539 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4540 This produces more-accurate results.
4542 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4544 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4545 changes (Bug#12088).
4547 2012-09-08 Chong Yidong <cyd@gnu.org>
4549 * syntax.c (Fstring_to_syntax): Doc fix.
4551 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4553 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4554 in the internal border.
4555 (x_set_window_size): Remove static variables and their usage.
4556 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4557 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4558 Remove fringe/internal border adjustment (Bug#11052).
4559 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4560 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4561 (ns_fix_rect_ibw): Remove.
4562 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4563 (ns_dumpglyphs_box_or_relief): Ditto.
4564 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4566 (ns_dumpglyphs_image): Ditto.
4567 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4569 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4570 their usage. Add fringe_extended_p and its use as in other terms.
4571 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4572 scroll bar was removed.
4573 (updateFrameSize): New function.
4574 (windowDidResize): Move code to updateFrameSize and call it.
4576 * nsterm.h (EmacsView): Add updateFrameSize.
4578 2012-09-07 Chong Yidong <cyd@gnu.org>
4580 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4582 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4584 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4586 More signal-handler cleanup (Bug#12327).
4587 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4588 Problem introduced when merging patches. Noted by Eli Zaretskii in
4589 <http://bugs.gnu.org/12327#67>.
4590 * floatfns.c: Comment fix.
4591 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4592 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4593 and anyway the declaration is harmless even if SIGDANGER is not defined.
4594 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4595 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4596 source files not surprisingly expected syssignal.h to define, or
4597 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4598 Include <sys/ioctl.h>, for FIONREAD.
4599 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4600 This eliminates a problem whereby other files mysteriously had
4601 to include "syssignal.h" before including "systty.h" if they
4602 wanted to use "#ifdef SIGIO".
4604 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4606 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4608 * w32.c (sigemptyset): Empty the set.
4609 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4611 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4613 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4615 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4616 (mark_object): Likewise for frame objects.
4618 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4620 * syssignal.h (handle_on_main_thread): Always declare,
4621 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4622 This ports to platforms without HAVE_PTHREAD.
4624 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4626 Signal-handler cleanup (Bug#12327).
4627 Emacs's signal handlers were written in the old 4.2BSD style with
4628 sigblock and sigmask and so forth, and this led to some
4629 inefficiencies and confusion. Rewrite these to use
4630 pthread_sigmask etc. without copying signal sets around. Also,
4631 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4632 'signal', and instead use functions that do not attempt to take
4633 over the system name space. This patch causes Emacs's text
4634 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4635 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4636 Do not include <signal.h> or "syssignal.h", as these
4637 modules do not use signals.
4638 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4639 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4640 Do not include <signal.h>, as "syssignal.h" does that for us now.
4641 * atimer.c (sigmask_atimers): New function.
4642 (block_atimers, unblock_atimers): New functions,
4643 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4645 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4646 no longer needed here.
4647 * emacs.c (main): Inspect existing signal handler with sigaction,
4648 so that there's no need to block and unblock SIGHUP.
4649 * sysdep.c (struct save_signal): New member 'action', replacing
4650 old member 'handler'.
4651 (save_signal_handlers, restore_signal_handlers):
4652 Use sigaction instead of 'signal' to save and restore.
4653 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4654 New function. All users of 'signal' modified to use set_sighandler
4655 if they're writeonly, and to use sys_signal if they're read+write.
4656 (emacs_sigaction_init, forwarded_signal): New functions.
4657 (sys_signal): Remove. All uses replaced by calls to sigaction
4658 and emacs_sigaction_init, or by direct calls to 'signal'.
4659 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4660 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4661 all uses replaced by pthread_sigmask etc. calls.
4662 * syssignal.h: Include <signal.h>.
4663 (emacs_sigaction_init, forwarded_signal): New decls.
4664 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4665 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4666 (sigmask, sys_sigmask): Remove; no longer needed.
4667 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4668 (sigblock, sigunblock, sigfree):
4669 (sigsetmask) [!defined sigsetmask]:
4670 Remove. All uses replaced by pthread_sigmask.
4671 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4672 no longer need to be replaced, and its typical old uses
4673 are now done via emacs_sigaction_init and sigaction.
4674 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4675 (sys_sigdel): Remove; unused.
4676 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4678 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4680 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4681 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4683 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4685 Explicitly mark buffer_defaults and buffer_local_symbols.
4686 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4687 mark_local_symbols here.
4688 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4689 since special buffers aren't marked here any more.
4690 (allocate_buffer): Chain new buffer with all_buffers here...
4691 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4693 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4694 (syms_of_buffer): Remove staticpro of the above.
4695 (init_buffer_once): Set names for buffer_defaults and
4696 buffer_local_symbols.
4698 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4700 Use bool for booleans in font-related modules.
4701 * font.c (font_intern_prop, font_style_to_value)
4702 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4703 (generate_otf_features, font_check_otf_features, font_check_otf)
4704 (font_match_p, font_list_entities, font_at):
4705 * fontset.c (fontset_id_valid_p, reorder_font_vector
4706 (fontset_find_font, Fset_fontset_font)
4707 (face_suitable_for_char_p) [0]:
4708 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4709 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4710 (m17n_flt_initialized, ftfont_shape_by_flt):
4711 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4712 * nsfont.m (nsfont_draw):
4713 * w32font.c (w32font_draw):
4714 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4715 Use bool for booleans.
4716 * font.h: Adjust to above API changes.
4717 (struct font, struct font_driver, struct font_driver_list):
4718 Use bool for booleans.
4719 (struct font): Remove useless member encoding_type.
4721 * fontset.c, xftfont.c: Omit unnecessary static decls.
4723 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4725 * alloc.c (mark_object): Revert window marking code
4726 since it's unsafe for the Fset_window_configuration.
4728 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4730 Fix race conditions with signal handlers and errno (Bug#12327).
4731 Be more systematic about preserving errno whenever a signal
4732 handler returns, even if it's not in the main thread. Do this by
4733 renaming signal handlers to distinguish between signal delivery
4734 and signal handling. All uses changed.
4735 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4736 * data.c (deliver_arith_signal): Rename from arith_error.
4737 * dispnew.c (deliver_window_change_signal): Rename from
4738 window_change_signal.
4739 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4740 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4741 * keyboard.c (deliver_input_available_signal): Rename from
4742 input_available_signal.
4743 (deliver_user_signal): Rename from handle_user_signal.
4744 (deliver_interrupt_signal): Rename from interrupt_signal.
4745 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4746 (deliver_child_signal): Rename from sigchld_handler.
4747 * atimer.c (handle_alarm_signal):
4748 * data.c (handle_arith_signal):
4749 * dispnew.c (handle_window_change_signal):
4750 * emacs.c (handle_fatal_signal, handle_danger_signal):
4751 * keyboard.c (handle_input_available_signal):
4752 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4753 * process.c (handle_pipe_signal, handle_child_signal):
4754 New functions, with the actual signal-handling code taken from the
4755 original respective signal handlers, sans the sporadic attempts to
4756 preserve errno, since that's now done by handle_on_main_thread.
4757 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4758 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4759 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4761 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4762 Move initialization of main_thread to sysdep.c's init_signals.
4763 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4764 our usage, and simplifies the mainline code.
4765 (record_child_status_change): New static function, as a helper
4766 for handle_child_signal, and with most of the old child handler's
4768 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4769 (handle_child_signal): Use the above.
4770 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4771 Moved here from emacs.c.
4772 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4773 code moved here from emacs.c's main function.
4774 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4775 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4776 This lets callers save and restore errno properly.
4778 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4780 Remove redundant or unused things here and there.
4781 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4782 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4783 * editfns.c (Fcompare_buffer_substrings): Likewise.
4784 * frame.h (struct terminal, struct font_driver_list):
4785 Remove redundant declarations.
4786 * window.h (Qleft, Qright): Likewise.
4788 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4790 Do not mark objects from deleted buffers, windows and frames.
4791 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4792 (mark_object): Likewise for windows and frames.
4794 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4796 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4797 buffer_defaults and buffer_local_symbols as valid objects.
4798 Return special value to denote them.
4800 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4802 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4803 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4804 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4805 (file_name_absolute_p, Fsubstitute_in_file_name):
4806 (check_executable, check_writable, Ffile_accessible_directory_p)
4807 (Fset_file_selinux_context, Fdefault_file_modes)
4808 (Finsert_file_contents, choose_write_coding_system)
4809 (Fwrite_region, build_annotations, a_write, e_write)
4811 * filelock.c (boot_time_initialized, get_boot_time)
4812 (get_boot_time_1, lock_file_1, within_one_second):
4813 * floatfns.c (in_float):
4814 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4815 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4816 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4817 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4818 * window.c (compare_window_configurations):
4819 Use bool for booleans.
4820 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4821 (Fdefault_file_modes): Now mode_t, not int, for modes.
4822 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4823 (internal_delete_file): Now returns void, not a (boolean) int,
4824 since nobody was looking at the return value.
4825 * lisp.h, window.h: Adjust to above API changes.
4827 * xdisp.c (set_message): Simplify and reindent last change.
4829 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4831 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4833 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4835 * eval.c (call_debugger): Make the function non-static so that we
4836 can call it from set_message.
4838 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4839 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4841 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4843 Give more-useful info on a fatal error (Bug#12328).
4844 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4845 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4846 of doing the work ourselves.
4847 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4848 do most of the work.
4849 (fatal_error_backtrace): New function, taken from the guts
4850 of the old fatal_error_signal, but with a new option to output
4852 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4853 info about the signal than just its number.
4854 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4855 * sysdep.c: Include <execinfo.h>
4856 (emacs_backtrace): New function, taken partly from the previous
4857 code of the 'die' function.
4858 (emacs_abort): Call fatal_error_backtrace rather than abort.
4860 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4862 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4863 eager (load-time) macro-expansion.
4864 * lisp.mk (lisp): Add macroexp.
4866 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4868 Simplify redefinition of 'abort' (Bug#12316).
4869 Do not try to redefine the 'abort' function. Instead, redo
4870 the code so that it calls 'emacs_abort' rather than 'abort'.
4871 This removes the need for the NO_ABORT configure-time macro
4872 and makes it easier to change the abort code to do a backtrace.
4873 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4874 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4875 Remove; sysdep.c's emacs_abort now takes its place.
4876 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4877 'abort' changed to use 'emacs_abort'.
4878 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4879 (abort) [!defined abort]: Rename to ...
4880 (emacs_abort): ... new name.
4881 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4882 the place of the old 'abort' in emacs.c.
4883 * w32.c, w32fns.c (abort): Do not #undef.
4884 * w32.c (emacs_abort): Rename from w32_abort.
4886 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4888 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4889 offsets[j].dv, since the y axis of the screen coordinates points
4890 down, while the y axis of the font definition coordinates points
4891 up. This fixes display of Arabic diacritics such as KASRA and
4892 KASRATAN. (Bug#11860)
4894 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4896 Be more systematic about _setjmp vs setjmp.
4897 * alloc.c (test_setjmp, mark_stack):
4898 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4899 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4900 (png_load, my_error_exit, jpeg_load):
4901 * process.c (send_process_trap, send_process):
4902 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4903 The underscored versions are up to 30x faster on some hosts.
4904 Formerly, the code used setjmp+longjmp sometimes and
4905 _setjmp+_longjmp at other times, with no particular reason to
4906 prefer setjmp+longjmp.
4908 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4910 Fix minor problem found by static checking.
4911 * buffer.c (Fdelete_all_overlays): Return nil.
4913 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4915 * buffer.c (Fdelete_all_overlays): New function.
4917 2012-09-03 Chong Yidong <cyd@gnu.org>
4919 * gtkutil.c: Add extern decl for Qxft.
4921 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4923 * emacs.c, eval.c: Use bool for boolean.
4924 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

4932 * process.c (read_process_output, exec_sentinel):
4933 Use bool for booleans.
4934 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4935 All callers changed.
4936 * eval.c (interactive_p): Omit always-true boolean argument
4937 EXCLUDE_SUBRS_P. All callers changed.
4938 * dispextern.h, lisp.h: Reflect above API changes.
4939 * firstfile.c (dummy): Use the address of 'main', whose signature
4940 won't change, instead of the address of 'initialize', whose
4941 signature just changed from int to bool.
4942 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4943 * msdos.c (fatal_error_in_progress): ... from here.
4944 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4946 (redisplay_internal, unwind_redisplay): Simply clear
4947 REDISPLAYING_P when unwinding, instead of saving its previous,
4948 always-false value and then restoring it.
4950 Clean up some extern decls.
4951 Mostly, this hoists extern decls out of .c files and into .h files.
4952 That way, we're more likely to catch errors if the interfaces change.
4953 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4954 declare xg_mark_data.
4955 * dispextern.h (x_frame_parm_handlers):
4957 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4958 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4959 (Qultra_bold, Qoblique, Qitalic):
4960 Move extern decl here from .c file.

4973 * xfont.c (x_clear_errors):
4974 * xterm.c (x_frame_parm_handlers):
4975 Remove now-redundant extern decls.
4976 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4977 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4979 * xfaces.c: Remove unnecessary static decls.
4980 * xterm.c (updating_frame): Remove decl of nonexistent object.
4982 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4983 when building globals.h, as the objects that are not built on
4984 this host are not needed to compile C files on this host.
4986 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4988 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

5040 offset adjustment values separately for each cluster. (Bug#11860)
5042 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5043 it, GCC doesn't see prototypes of w32_delayed_load, and complains
5044 about implicit conversions from integer to pointer.
5046 2012-09-01 Daniel Colascione <dancol@dancol.org>

5102 window system declarations.
5104 * frame.h: Move common functions here: set_frame_menubar,
5105 x_set_window_size, x_sync, x_get_focus_frame,
5106 x_set_mouse_position, x_set_mouse_pixel_position,
5107 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5137 the frames which are reachable from Vframe_list.
5138 * term.c (mark_ttys): Remove.
5139 (init_tty): Safely initialize 'top_frame' slot with Qnil.

5164 for GCC 4.7.1 x86-64.
5166 2012-08-30 Glenn Morris <rgm@gnu.org>
5168 * lread.c (init_lread): For out-of-tree builds, only add the
5169 source directory's site-lisp dir to the load-path if it exists,
5170 consistent with in-tree builds. (Bug#12302)
5172 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
5174 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

5191 Handle click on close button as quit.
5193 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5194 Add window_closed and button_values. Add void as return value for
5195 add(Button|String|Split). addButton takes int instead of Lisp_Object.

5406 It was meant to be temporary and it often doesn't work,
5407 because when IDX has side effects the behavior of IDX==IDX
5408 is undefined. See Stefan Monnier in
5409 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.

5422 says no events are pending.
5423 (gfds, gfds_size): Remove these static vars.
5424 (xgselect_initialize): Remove; no longer needed.
5425 All uses and decls removed.

5455 Use bool for booleans, instead of int.
5456 * lisp.h, process.h: Adjust prototypes to match above changes.
5457 * callint.c (Fcall_interactively): Don't assume the mark's
5458 offset fits in 'int'.

5471 Use bool for booleans, instead of int.
5472 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5473 since the 1-or-0 return value is always ignored anyway.
5474 (mmap_initialized_p):
5475 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5476 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5478 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5480 * bidi.c: Use bool for boolean.
5481 This is a bit more readable, and makes the text segment of bidi.o
5482 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5483 Presumably it's faster too.
5484 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5486 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5487 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
5488 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
5489 (bidi_explicit_dir_char, bidi_level_of_next_char)
5490 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5491 Use bool for booleans, instead of int.
5492 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5493 (bidi_unshelve_cache): Adjust decls to match code.
5495 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5497 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5500 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5502 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5503 * atimer.h: Include <stdbool.h>.
5505 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5507 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5508 compile time tests instead of run time tests on systems that do
5510 (FRAME_MAC_P): Remove leftover from deleted code.
5511 * frame.c (syms_of_frame): Remove leftover from deleted code.
5513 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5515 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5517 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5519 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5520 Otherwise, the compiler complains about (A?B:C) where B is void
5521 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5522 (fontset_add): Return void, for FONTSET_ADD.
5524 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5526 * alloc.c: Use bool for booleans.
5527 (gc_in_progress, abort_on_gc)
5528 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5529 (dont_register_blocks) [GC_MALLOC_CHECK]:
5530 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5531 (check_string_bytes, make_specified_string, memory_full)
5532 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5533 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5534 (mark_stack, valid_pointer_p, make_pure_string)
5535 (Fgarbage_collect, survives_gc_p, gc_sweep):
5536 Use bool for booleans, instead of int.
5537 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5538 Remove unused local.
5539 * alloc.c (PURE_POINTER_P):
5540 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5541 * editfns.c (Fformat):
5542 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5544 * fns.c (sweep_weak_table):
5545 * lisp.h (suppress_checking, push_message, survives_gc_p)
5546 (make_pure_string, gc_in_progress, abort_on_gc):
5547 * lread.c (readchar, read1):
5548 * print.c (Fprin1_to_string):
5549 * xdisp.c (push_message):
5550 Use bool for booleans affected directly or indirectly by
5553 Make recently-introduced setters macros.
5554 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5555 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5556 (set_fontset_default, set_fontset_fallback): Rename from their
5557 upper-case counterparts, and make them functions rather than macros.
5558 This is more consistent with the other recently-introduced setters.
5559 These don't need to be inline, since they're local.
5561 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5563 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5564 the loop (Bug#12247).
5566 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5568 * lisp.h (vcopy): Use memcpy rather than our own loop.
5569 This fixes a performance regression introduced by the recent
5570 addition of vcopy. This means 'vcopy' will need to be modified
5571 for a copying collector, but that's OK. Also, tighten the
5572 checking in the assertion.
5574 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5576 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5577 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5578 non-base glyph for the width of the base character, according to
5579 what x_draw_composite_glyph_string_foreground expects.
5580 Generate WADJUST value according to composition_gstring_width's
5581 expectations, to produce correct width of the composed character.
5582 Reverse the sign of the DU offset produced by ScriptPlace.
5584 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5586 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5588 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5590 Avoid direct writes to contents member of struct Lisp_Vector.
5591 * lisp.h (vcopy): New function to copy data into vector.
5592 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5593 * fns.c (Ffillarray): Use ASET.
5594 * keyboard.c (timer_check_2): Use AREF and ASET.
5595 (append_tool_bar_item, Frecent_keys): Use vcopy.
5596 * lread.c (read_vector): Use ASET.
5597 * msdos.c (Frecent_doskeys): Use vcopy.
5598 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5599 (Finternal_merge_in_global_face): Use ASET and vcopy.
5600 * xfont.c (xfont_list_pattern): Likewise.
5602 2012-08-21 Martin Rudalics <rudalics@gmx.at>
5604 * window.c (Fwindow_point): For the selected window always return
5605 the position of its buffer's point.
5606 (Fset_window_point): For the selected window always go in its
5607 buffer to the specified position.
5609 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5611 Setter macros for fontsets.
5612 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5613 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5614 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5617 2012-08-20 Glenn Morris <rgm@gnu.org>
5619 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5620 Don't assume that `ln -f' works.
5622 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5624 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5625 and later about non-assignments with no effect. See discussion at
5626 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5629 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5631 Inline setter functions for Lisp_Objects slots of struct specbinding.
5632 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5635 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5637 * window.c (select_window): Always make selected window's buffer
5640 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5642 Use AREF and ASET for docstrings of category tables.
5643 * category.h (CATEGORY_DOCSTRING): Use AREF.
5644 (SET_CATEGORY_DOCSTRING): Use ASET.
5645 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5647 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5649 Inline setter functions for hash table members.
5650 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5651 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5652 (set_hash_key_and_value, set_hash_index, set_hash_next)
5653 (set_hash_hash): New functions.
5654 * charset.c, fns.c: Adjust users.
5656 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5658 Inline getter and setter functions for per-buffer values.
5659 * buffer.h (per_buffer_default, set_per_buffer_default)
5660 (per_buffer_value, set_per_buffer_value): New functions.
5661 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5662 * buffer.c, data.c: Adjust users.
5664 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5666 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5668 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5670 Rely on <config.h> + <unistd.h> to declare 'environ',
5671 as gnulib does this if the system doesn't.
5672 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5673 Remove declaration. MS-Windows declares it on stdlib.h which is
5674 included by conf_post.h.
5675 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5676 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5677 * vm-limit.c: Include <unistd.h>, for 'environ'.
5679 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5680 (start_of_data): Remove decl; mem-limits.h provides it.
5682 * xdisp.c (handle_invisible_prop): Make it a bit faster
5683 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5685 2012-08-19 Chong Yidong <cyd@gnu.org>
5687 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5690 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5692 * .gdbinit: Use call instead of set when calling a function in the
5695 * data.c (set_internal): Don't use set_blv_found.
5696 (Fkill_local_variable): Likewise.
5698 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5700 * nsfont.m (ns_ascii_average_width): Ensure the string
5701 ascii_printable is initialized with a null-terminated character
5702 array. Otherwise, it can contain undesired extra characters.
5704 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5706 port new setting code to Sun C 5.8 2005/10/13
5707 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5708 Return void, not Lisp_Object. Otherwise, the compiler
5709 complains about (A?B:C) where B is void and C is Lisp_Object
5710 when compiling CHAR_TABLE_SET, due to the recent change to
5711 the API of sub_char_table_set_contents.
5713 2012-08-18 Chong Yidong <cyd@gnu.org>
5715 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5716 for the string case (Bug#3874).
5718 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5720 * buffer.h (BSET): Remove (Bug#12215).

5799 are compiled into code.
5800 (tset_param_alist): New setter function.
5802 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>

5837 A few more naming-convention fixes for getters and setters.
5838 * buffer.c (set_buffer_overlays_before): Move here from buffer.h,

5840 (set_buffer_overlays_after): Move here from buffer.h, and rename
5841 from buffer_overlays_set_after.

5869 "CSET (XCHAR_TABLE (char_table), parent, parent);" with
5870 "set_char_table_parent (char_table, parent);".
5871 The old version was confusing because it used the same name
5872 'parent' for two different things.
5874 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
5876 Functions to get and set Lisp_Object fields of buffer-local variables.

5885 font spec, make the font's attributes take precedence over
5886 directly-specified attributes.
5887 (merge_face_ref): Recognize :font.
5889 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
5891 Do not use memcpy for copying intervals.
5892 * intervals.c (reproduce_interval): New function.

6543 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6544 * w32.c (init_environment): Change the default values of many
6545 environment variables in dflt_envvars[] to NULL, to avoid pushing
6546 them into environment when they were not already defined.
6547 Remove the code that deletes site-lisp subdirectories from the default
6548 value of EMACSLOADPATH, as it is no longer needed.
6549 (check_windows_init_file): Now external, not static.
6550 Use Vload_path as is, without adding anything, as this function is now
6551 called when Vload_path is already set up.
6553 * w32.h (check_windows_init_file): Add prototype.
6555 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6562 installation tree, as appropriate.
6564 * callproc.c (init_callproc_1): Call decode_env_path instead of
6565 doing its equivalent by hand.
6566 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
6567 the code that sets Vexec_path run on MS-Windows.
6569 * lread.c (init_lread): Add comments to #ifdef's.
6571 * msdos.c (dos_set_window_size, IT_update_begin)

6583 Remove unnecessary casts involving pointers.
6584 These casts are no longer needed now that we assume C89 or later,

6598 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6599 Remove unnecessary pointer casts.
6600 * alloc.c (record_xmalloc): New function.
6601 * lisp.h (record_xmalloc): New decl.
6602 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6603 more like a function. This is because the pointer cast is not
6604 needed. All uses changed.
6605 * print.c (print_string, print_error_message): Avoid length recalc.
6607 Improve fix for macroexp crash with debugging (Bug#12118).
6608 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6609 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6610 not supposed to be invoked from the garbage collector.
6611 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
6612 (gc_aset): New function, which is like ASET but can be
6613 used in the garbage collector.
6614 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

6629 headers (most versions of MinGW w32api don't).
6630 (get_security_info, create_symbolic_link)
6631 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
6633 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks

6638 have the required privileges.
6639 (get_file_security_desc_by_name): Rename from
6640 get_file_security_desc.

6642 with addition of handling of symlinks and support for 'lstat'.
6643 If possible, get file's attributes and security information by
6644 handle, not by name. Produce S_IFLNK bit for symlinks, when
6645 called from 'lstat'.
6646 (stat, lstat): New functions, call 'stat_worker'.
6647 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6648 symlinks when the underlying filesystem supports them.
6650 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6652 Fix macroexp crash on Windows with debugging (Bug#12118).
6653 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6654 checking subscripts; problem introduced with the recent
6655 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6656 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6657 since it's used in non-static inline functions now.
6659 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6660 Don't assume buffer size fits in 'int'. Remove unused local.

6677 * category.c (CATEGORY_INLINE):
6678 * character.c (CHARACTER_INLINE):
6679 * charset.c (CHARSET_INLINE):
6680 * composite.c (COMPOSITE_INLINE):
6681 * dispnew.c (DISPEXTERN_INLINE):
6682 * sysdep.c (SYSTIME_INLINE):
6683 Define to EXTERN_INLINE, so that the corresponding functions
6684 are compiled into code.
6685 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6686 (INLINE_HEADER_END): New macros.
6687 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6707 hard-coding the path separator.
6709 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6711 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6712 This how ASET and AREF are supposed to work, and makes
6713 it easier to think about future improvements. See
6714 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6715 * charset.h (set_charset_attr): New function.

7097 (w32_kbd_patch_key, key_event): Use the codepage returned by
7098 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

7207 the fix for 12036 would have avoided some of the problems noted in
7208 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7209 would have been more obvious.

7220 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7221 not be usable in #if. This simplifies things.
7223 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7225 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7231 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7232 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7233 Adjust to changes in lisp.h and emacs.c, by using
7234 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7235 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7236 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7237 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7238 instead of gdb_valbits.

7243 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7244 (xreload, hook-run, hookpost-run): Remove.

7277 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7278 than macros. This simplifies debugging in the usual case, since
7279 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7280 and it allows expressions involving EMACS_INT casts.
7281 * .gdbinit (xreload): Simplify by using EMACS_INT cast.

7336 * buffer.c (Fbuffer_swap_text): Swap indirections too.
7337 This avoids crash reported by Christoph Scholtes at
7338 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
7340 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
7342 * nsmenu.m (Popdown_data): New struct.

7367 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
7368 as it's limited by the amount of memory, not by INT_MAX.

8146 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8147 * nsterm.m (ns_term_init):
8148 Avoid the need for strncpy, by using build_string or
8149 make_unibyte_string directly. Use dtoastr, not snprintf.
8150 * process.c (Fmake_network_process): Diagnose service names that
8151 are too long, rather than silently truncating them or creating
8152 non-null-terminated names.
8153 (Fnetwork_interface_info): Likewise, for interface names.
8154 * sysdep.c (system_process_attributes) [GNU_LINUX]:
8155 Prefer sprintf to strncat.
8156 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

8182 Optimize pure C strings initialization.
8183 * lisp.h (make_pure_string): Fix prototype.
8184 (build_pure_c_string): New function, defined as static inline. This
8185 provides a better opportunity to optimize away calls to strlen when
8186 the function is called with compile-time constant argument.
8187 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8188 argument, adjust users accordingly. Use build_pure_c_string where
8190 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8191 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8192 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8194 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8196 Avoid calls to strlen in miscellaneous functions.
8197 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8198 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8199 * lread.c (openp): Likewise.
8201 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8203 Avoid calls to strlen in path processing functions.
8204 * fileio.c (file_name_as_directory): Add comment. Change to add
8205 srclen argument and return the length of result. Adjust users

8209 Adjust users accordingly.
8210 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8212 2012-07-10 Glenn Morris <rgm@gnu.org>

8219 * s/gnu.h (DATA_START): Move definitions to configure.
8221 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8222 We include usg5-4-common.h, which defines them both.
8224 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8225 O_RDONLY already includes it).
8227 Stop ns builds setting the EMACSLOADPATH environment variable.
8228 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8229 Now it does not set EMACSLOADPATH, just returns the load-path string.
8230 * nsterm.h: Update accordingly.
8231 * lread.c [HAVE_NS]: Include nsterm.h.
8232 (init_lread) [HAVE_NS]: Use ns_load_path.

8235 2012-07-09 Glenn Morris <rgm@gnu.org>
8237 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8238 since the included bsd-common.h does so.
8240 Stop ns builds setting the EMACSPATH environment variable.
8241 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8242 (ns_init_paths): Do not set EMACSPATH.
8243 * nsterm.h (ns_exec_path): Add it.
8244 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8247 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8249 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8251 * process.c (wait_reading_process_output): 'waitchannels' was unset
8252 when read_kbd || !NILP (wait_for_cell); fix this.
8254 Add GCC-style 'const' attribute to functions that can use it.
8255 * character.h (char_resolve_modifier_mask):
8256 * keyboard.h (make_ctrl_char):
8257 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

8266 Add decls with ATTRIBUTE_CONST.
8268 Minor improvements to make_formatted_string.
8269 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8270 where int is good enough, as vsprintf returns an int.
8271 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8273 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8275 Use make_formatted_string to avoid double length calculation.
8276 * lisp.h (make_formatted_string): New prototype.

8300 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8302 Move marker debugging code under MARKER_DEBUG.
8303 * marker.c (MARKER_DEBUG): Move marker debugging code under
8304 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8305 for bootstrap with --enable-checking (~3x slowdown reported
8306 by Juanma Barranquero <lekktu@gmail.com>).
8307 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8309 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8311 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8312 See <http://bugs.gnu.org/11825#29>.
8314 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8316 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8317 has no font, use the frame's font. (Bug#11813)
8318 (display_line): Add commentary about displaying truncation glyphs
8320 (produce_special_glyphs): Move here from term.c.
8322 * term.c (produce_special_glyphs): Move to xdisp.c.
8324 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8327 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8329 * xdisp.c (display_line): Avoid warning about implicit declaration
8332 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8334 * lisp.h: Remove empty conditional.
8336 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8338 * lread.c (load_path_check): Now static.
8340 Fix some minor --with-ns problems found by static checking.
8341 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8342 (x_set_font) [!HAVE_X_WINDOWS]:
8343 * image.c (xpm_load_image) [HAVE_NS]:
8344 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8345 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8346 Remove unused local.
8347 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8348 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8349 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8350 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8351 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8352 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8353 Fix pointer signedness problem.
8354 * xfaces.c (FRAME_X_FONT_TABLE):
8355 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8357 2012-07-07 Glenn Morris <rgm@gnu.org>
8359 * lread.c (load_path_check): New function, split from init_lread.
8360 (init_lread): Reorganize. Motivation:
8361 If EMACSLOADPATH is set, check/warn about that rather than the
8362 defaults, which we are not going to use. Hence we can remove
8363 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8364 Don't warn if site-lisp directories are missing.
8365 If not installed, start from a blank load-path, since
8366 PATH_LOADSEARCH refers to the eventual installation directories.
8368 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8370 Support truncation and continuation glyphs on GUI frames, when
8371 fringes are disabled. (Bug#11832)
8372 * xdisp.c (init_iterator): Get dimensions of truncation and
8373 continuation glyphs even if on GUI frames.
8374 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8375 or both, are absent.
8376 (start_display, move_it_in_display_line_to): Handle the case of a
8377 GUI frame without a fringe to display continuation or truncation
8379 (insert_left_trunc_glyphs): Support GUI frames: make sure
8380 truncation glyphs overwrite enough glyphs from the current line to
8381 have sufficient space in pixels.
8382 (display_line): Support truncation and continuation glyphs on GUI
8383 frames. If some spare pixels are left on the line after inserting
8384 the truncation glyphs, fill that space with a stretch glyph of a
8385 suitably computed width.
8387 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8388 produce_glyphs, to support GUI sessions.
8390 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8392 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8394 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8396 Do not require float-time's arg to fit in time_t (Bug#11825).
8397 This works better on hosts where time_t is unsigned, and where
8398 float-time is applied to the (negative) difference between two times.
8399 * editfns.c (decode_time_components): Last arg is now double *,
8400 not int *, and means to store all the result as a double, without
8401 worrying about whether the seconds part fits in time_t.
8402 All callers changed.
8403 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8404 All callers changed.
8405 (Ffloat_time): Do not fail merely because the specified time falls
8406 outside of time_t range.
8408 2012-07-07 Glenn Morris <rgm@gnu.org>
8410 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
8411 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

8414 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
8416 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
8417 Update dependencies.
8419 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8421 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8423 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

8425 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8426 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8427 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

8430 * xfont.c (compare_font_names): Redo to omit the need for casts.
8432 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8434 * xfns.c (Fx_change_window_property): Doc fix.
8435 * w32fns.c (Fx_change_window_property): Doc fix.
8437 * w32fns.c (Fx_window_property): Accept the same arguments as the
8438 X Windows version. Doc fix.
8439 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8441 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8442 Eli Zaretskii <eliz@gnu.org>
8444 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8445 Windows-specific code from nt/config.nt moved here.
8446 Obsolete settings removed.
8448 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8450 * process.c: Avoid unnecessary calls to gettime.
8451 (wait_reading_process_output): Don't get the time of day
8452 when gobbling data immediately and not waiting, as there's no need
8453 for it in that case. This removes a FIXME.
8455 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8457 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8458 is defined (Bug#11768).
8460 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8462 Fix marker debugging code.
8463 * marker.c (byte_char_debug_check): Do not perform the check
8464 if buffer is not multibyte.
8465 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8466 Call byte_char_debug_check with correct arguments.
8468 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8470 Compile marker debugging code only if ENABLE_CHECKING is defined.
8471 * marker.c (byte_char_debug_check, count_markers):
8472 Use only if ENABLE_CHECKING is defined.
8473 (byte_debug_flag): Remove.
8474 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8475 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8477 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8479 Avoid code repetition in marker-related functions.
8480 * marker.c (attach_marker): New function.
8481 (Fset_marker, set_marker_restricted, set_marker_both)
8482 (set_marker_restricted_both): Use it.
8483 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8484 Consistently rename charno to charpos.
8485 (marker_position): Add eassert.
8486 (marker_byte_position): Convert to eassert.

8505 * window.c (save_window_save): Likewise.
8507 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8509 Do not use Fdelete_overlay in delete_all_overlays
8510 to avoid redundant calls to unchain_overlay.
8511 * buffer.c (drop_overlay): New function.
8512 (delete_all_overlays, Fdelete_overlay): Use it.
8513 * minibuf.c (get_minibuffer): Fix comment.
8515 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8517 Port to OpenBSD 5.1 amd64.
8518 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8519 This is needed for OpenBSD, and should be harmless on all BSD systems.
8520 Also, include <sys/sysctl.h>, as it should be available on all
8521 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8522 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8523 use p_pid member, not kp_proc.pid.
8525 2012-07-06 Glenn Morris <rgm@gnu.org>
8527 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8529 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8531 More xmalloc and related cleanup.
8532 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
8533 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
8534 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:
8535 * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c:
8536 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
8537 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
8538 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
8539 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
8540 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8542 Omit needless casts involving void * pointers and allocation.
8543 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8544 as the former is more robust if P's type is changed.
8545 Prefer xzalloc to xmalloc + memset 0.
8546 Simplify malloc-or-realloc to realloc.
8547 Don't worry about xmalloc returning a null pointer.
8548 Prefer xstrdup to xmalloc + strcpy.
8549 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8551 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8552 alloca of a constant.
8554 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8556 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8557 hscroll is larger than the line width. Fixes long and futile
8558 looping inside extend_face_to_end_of_line (on a TTY) producing
8559 glyphs that are not needed and thrown away.
8561 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8563 * marker.c (set_marker_restricted_both): Simplify by using
8566 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

8576 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
8577 followed by gtk_box_set_homogeneous (Bug#11768).
8578 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8579 (update_theme_scrollbar_width, xg_create_scroll_bar):
8580 Use gtk_scrollbar_new (Bug#11768).
8581 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

8589 * xdisp.c (window_hscroll_limited): New function.
8590 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8591 coordinates when window's hscroll is set to insanely large
8594 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8596 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
8597 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
8599 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

8657 * fileio.c (time_error_value): Check the right error number.
8658 Problem reported by Troels Nielsen in
8659 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8661 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8663 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8664 This should be fixed in a better way; see Eli Zaretskii in
8665 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8666 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8668 * fileio.c (time_error_value): Rename from special_mtime.
8669 The old name's problems were noted by Eli Zaretskii in
8670 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8672 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8673 This variable's comment says Emacs needs at least one GDB-visible
8674 symbol of type enum pvec_type, to work around GDB problems.
8675 The symbol's value doesn't matter.
8677 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8678 that causes compilation to fail on pre-C99 compilers.
8680 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8682 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
8683 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
8685 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8687 * buffer.c (init_buffer_once): Fix initialization of
8688 headers for buffer_defaults and buffer_local_symbols.
8689 Reported by Juanma Barranquero <lekktu@gmail.com>.
8691 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8693 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8694 * lisp.h (enum pvec_type): Use fewer bits.
8695 (PSEUDOVECTOR_SIZE_BITS): New constant.
8696 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8697 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8698 change in pvec_type.
8699 (PSEUDOVECTOR_TYPEP): New macro.
8700 (TYPED_PSEUDOVECTORP): Use it.
8701 * fns.c (internal_equal): Adapt code to extract pvectype.

8703 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
8704 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
8705 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8706 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8707 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8708 abusing vector->header.next.nbytes.
8709 (live_vector_p): Use PVEC_TYPE.
8710 (mark_object): Adapt code to extract pvectype. Use switch.
8712 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8714 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8715 Tighten new eassert a bit.
8717 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8719 Fix compilation with --enable-gcc-warnings and -O1
8721 * doprnt.c (doprnt): Change type of tem to int, initialize
8722 to avoid compiler warning. Add eassert.
8723 * search.c (simple_search): Initialize match_byte to avoid
8724 compiler warning. Add eassert.
8726 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8728 Avoid weird behavior with large horizontal scrolls.
8729 Without this change, for example, large hscroll values would
8730 mess up Emacs's display on Fedora 15 x86, presumably due to
8731 overflows in int calculations in the display code.
8732 Also, if buffers had long lines, Emacs would freeze.
8733 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8734 (set_window_hscroll): New function, containing the old guts of
8735 Fset_window_hscroll. Return the clipped value.
8736 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8737 This avoids the need to check against PTRDIFF_MAX.
8739 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8741 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8743 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8745 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8747 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8748 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8749 since GCC 4.4.6 issues a bogus warning for them.
8751 Fix bugs in file timestamp newness comparisons.
8752 * fileio.c (Ffile_newer_than_file_p):
8753 * lread.c (Fload): Use full timestamp resolution of files,
8754 not just the 1-second resolution, so that files that are only
8755 slightly newer still count as newer.
8756 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8757 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8759 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8761 * fileio.c: Improve handling of file time marker. (Bug#11852)
8762 (special_mtime): New function.
8763 (Finsert_file_contents, Fverify_visited_file_modtime):
8764 Use it to set special mtime values consistently.
8766 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8768 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8769 marker for non-existing file. (Bug#11852)
8771 2012-07-03 Glenn Morris <rgm@gnu.org>
8773 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8774 and did not make it into globals.h).
8776 2012-07-03 Tom Tromey <tromey@redhat.com>
8778 * window.c (Fset_window_margins, Fset_window_fringes)
8779 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8780 * textprop.c (Fprevious_property_change): No longer static.
8781 * syntax.c (Fsyntax_table_p): No longer static.

8803 * intervals.h: Remove EXFUNs.
8804 * fontset.h: Remove EXFUN.

8812 * xterm.h: Remove EXFUN.
8814 2012-07-03 Glenn Morris <rgm@gnu.org>
8816 * lisp.h (Frandom): Make it visible to C.
8817 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8818 buffer for invisible buffers. (Bug#1229)
8820 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8822 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8823 values which aren't power of 2.
8824 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8825 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8828 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8830 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8832 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8834 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8836 * alloc.c (allocate_vector_block): Remove redundant
8837 calls to mallopt if DOUG_LEA_MALLOC is defined.
8838 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8839 avoid calls to mallopt if zero_vector is returned.
8841 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8843 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8844 is enabled, avoid dereferencing NULL current_sblock if
8847 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8849 Cleanup basic buffer management.
8850 * buffer.h (struct buffer): Change layout to use generic vector
8851 marking code. Fix some comments. Change type of 'clip_changed'
8852 to bitfield. Remove unused #ifndef old.
8853 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8854 (GET_OVERLAYS_AT): Fix indentation.
8855 (for_each_per_buffer_object_at): New macro.

8859 * alloc.c (allocate_buffer): Adjust to match new layout of
8860 struct buffer. Fix comment.
8861 (mark_overlay): New function.

8864 (mark_object): Use it. Adjust marking of misc objects
8865 and related comments.
8867 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8869 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8870 wrapper that is not needed because the wrapped code is a no-op (zero
8871 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8872 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8874 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8876 * alloc.c (mark_buffer): Simplify. Remove prototype.
8877 (mark_object): Add comment. Reorganize marking of vector-like
8878 objects. Use CHECK_LIVE for all vector-like objects except buffers
8879 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8880 Avoid redundant calls to mark_vectorlike for bool vectors.
8882 2012-06-30 Glenn Morris <rgm@gnu.org>
8884 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8886 * epaths.in (PATH_SITELOADSEARCH): New.
8887 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8888 This is rather than relying on --enable-locallisppath elements
8889 having "site-lisp" in their names. (Bug#10208#25, 11658)
8891 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8893 * w32proc.c (sys_select): Accept and ignore one more argument.
8895 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8897 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8898 (pselect) [!MS_DOS]: Redirect to sys_select.
8900 * sysdep.c: Don't include dos.h and dosfns.h.
8902 * process.c (sys_select):
8903 * msdos.c (sys_select): Accept one more argument and ignore it.
8905 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8906 adapt data types and code to that.
8909 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8910 which clashes with the gnulib function of the same name.
8912 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8914 * font.c (font_style_to_value, font_style_symbolic)
8915 (font_prop_validate_style): Add type checks for values in
8918 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8920 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8923 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8925 * xdisp.c (try_window_id): Undo last change.
8927 * w32.c (getwd): Adjust commentary about startup_dir.
8928 (init_environment): Always call sys_access, even in non-MSVC
8929 builds. Don't chdir to the directory of the Emacs executable.
8930 This undoes code from 1997 which was justified by the need to
8931 "avoid conflicts when removing and renaming directories". But its
8932 downside was that every relative file name was being interpreted
8933 relative to the directory of the Emacs executable, which can never
8934 be TRT. In particular, it broke sys_access when called with
8935 relative file names.
8936 (sys_access): Map GetLastError to errno.
8938 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8940 * window.h (struct window): Change type of 'fringes_outside_margins'

8944 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8947 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8949 * gnutls.c (emacs_gnutls_handshake):
8950 Add QUIT to make the loop interruptible.
8952 2012-06-29 Glenn Morris <rgm@gnu.org>
8954 * charset.c (init_charset): Make lack of etc/charsets fatal.
8956 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8958 * editfns.c (region_limit): Fix type mismatch.
8960 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8962 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8963 undefined. Convert from xassert to eassert.
8964 * nsmenu.m: Convert from xassert to eassert.
8965 * nsterm.m: Likewise.
8967 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8969 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8971 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8973 Avoid integer overflow on scroll-left and scroll-right.
8974 * window.c (HSCROLL_MAX): New macro.
8975 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8976 overflow when requested scroll falls outside ptrdiff_t range.
8978 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8980 * window.h (struct window): Change type of 'hscroll',
8981 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8982 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8983 Adjust users accordingly.
8984 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8985 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8986 from EMACS_INT to ptrdiff_t.
8987 (make_window): Omit redundant initialization.
8989 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
8991 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
8993 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8995 * window.h (struct window): Change type of 'use_time' and
8996 'sequence_number' from Lisp_Object to int.
8997 * frame.c (make_frame): Adjust users accordingly.

9005 enabled with --enable-checking=[all,glyphs] configure option.
9006 Fix GLYPH_DEBUG usage assuming that it may be undefined,
9007 adjust comments accordingly.

9058 avoid GCC warning about unused macro.
9060 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9062 * alloc.c (allocate_string): Omit intervals initialization.
9063 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9064 as in make_pure_string and make_pure_c_string.
9066 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9068 * alloc.c (allocate_string): Fix last change.
9070 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9073 to memset, add explicit initialization where appropriate.

9128 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9130 Use sprintf return value instead of invoking strlen on result.
9131 In the old days this wasn't portable, since some sprintf
9132 implementations returned char *. But they died out years ago and
9133 Emacs already assumes sprintf returns int.
9134 Similarly for float_to_string.
9135 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9136 * ccl.c (ccl_driver):
9137 * character.c (string_escape_byte8):

9140 * print.c (print_object):
9141 * xdisp.c (message_dolog):
9142 * xfns.c (syms_of_xfns):
9143 Use sprintf or float_to_string result to avoid need to call strlen.
9144 * data.c (Fnumber_to_string):
9145 Use make_unibyte_string, since the string must be ASCII.
9146 * lisp.h, print.c (float_to_string): Now returns int length.
9147 * term.c (produce_glyphless_glyph):
9148 Use sprintf result rather than recomputing it.
9150 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9151 * Makefile.in (ALL_CFLAGS):
9152 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9153 * gmalloc.c, regex.c: Include <config.h> unconditionally.

9157 * dispextern.h (xstrcasecmp): Define to library function
9158 strcasecmp if available.
9159 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.

9174 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9176 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9177 sprintf already null-terminates its output.
9179 * xfns.c (x_window): Remove redundant cast.
9181 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9183 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9184 `const char *' to `char *' to avoid compiler warning.
9186 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9188 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9189 instead of truncating it to 63 (admittedly a generous limit).
9191 * process.c: Fix spelling and caps in comments.
9193 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9195 * emacs.c (setpgrp): Remove definition, unused.

9242 Remove unnecessary forward decls.
9244 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9246 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

9248 * dispnew.c (Fsleep_for, sit_for):
9249 * keyboard.c (kbd_buffer_get_event):
9250 * process.c (Faccept_process_output):
9251 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9252 This improves on the previous patch, which introduced a bug
9253 when time_t is unsigned and as wide as intmax_t.
9254 See <http://bugs.gnu.org/9000#51>.
9256 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9258 * dispnew.c (sit_for, Fsleep_for):
9259 * keyboard.c (kbd_buffer_get_event):

9272 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9273 Privately reported by Herbert J. Skuhra.
9274 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9276 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9277 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9279 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9281 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9282 last argument of make_unibyte_string.
9284 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9285 language ID in the event parameters.
9287 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9288 event.code, not the obscure "character set ID".

9311 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9312 Privately reported by Herbert J. Skuhra.

9319 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9321 Support higher-resolution time stamps (Bug#9000).
9322 The time stamps are only nanosecond-resolution at the C level,
9323 since that's the best that any real-world system supports now.
9324 But they are picosecond-resolution at the Lisp level, as that's
9325 easy, and leaves room for future OS improvements.
9327 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9330 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9331 Don't get current time unless it's needed.
9333 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9334 now provides it if it's absent.
9335 (start_atimer): Port to higher-res time stamps.
9336 Check for time stamp overflow. Don't get current time more
9337 often than is needed.
9339 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9340 Include systime.h, not time.h.
9341 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9343 * dired.c: Include stat-time.h.
9344 (Ffile-attributes): File times now have higher resolution.
9346 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9347 (struct image): Timestamp now has higher resolution.
9349 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9350 has at least microseconds now. All uses removed.
9351 (update_frame, update_single_window, update_window, update_frame_1)
9352 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9353 (duration_to_sec_usec): Remove; no longer needed.
9355 * editfns.c (time_overflow): Now extern.
9356 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9357 (float-time, Fformat_time_string, Fcurrent_time_string)
9358 (Fcurrent_time_zone): Accept and generate higher-resolution
9360 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9361 (decode_time_components, lisp_seconds_argument): New functions.
9362 (make_time): Now static.
9363 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9364 Report an error if the time is invalid, rather than having the caller
9367 * fileio.c: Include <stat-time.h>
9368 (Fcopy_file): Copy higher-resolution time stamps.
9369 Prefer to set the time stamp via a file descriptor if that works.
9370 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9371 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9372 (Fvisited_file_modtime, Fset_visited_file_modtime):
9373 Support higher-resolution time stamps.
9375 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9377 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9379 * image.c (prepare_image_for_display, clear_image_cache)
9380 (lookup_image): Port to higer-resolution time stamps.
9382 * keyboard.c (start_polling, bind_polling_period):
9383 Check for time stamp overflow.
9384 (read_char, kbd_buffer_get_event, timer_start_idle)
9385 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9386 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9387 Port to higher-resolution time stamps. Do not assume time_t is signed.
9388 (decode_timer): New function. Timers are now vectors of length 9,
9389 not 8, to accommodate the picosecond component.
9390 (timer_check_2): Use it.
9392 * nsterm.m (select_timeout, timeval_subtract): Remove.
9393 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9394 as they're a bit more accurate and handle overflow better.
9395 (ns_select): Change prototype to be compatible with pselect.
9396 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9397 * nsterm.h (ns_select): Adjust prototype.
9399 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9400 us-resolution time stamps.
9401 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9403 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9405 * lisp.h (time_overflow): New decl.
9406 (wait_reading_process_output): First arg is now intmax_t, not int,
9407 to accommodate larger waits.
9409 * process.h (struct Lisp_Process.read_output_delay):
9410 Now counts nanoseconds, not microseconds.
9411 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9413 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9414 (wait_reading_process_output):
9415 Port to ns-resolution time stamps.
9416 (Faccept_process_output, wait_reading_process_output):
9417 Check for time stamp overflow. Do not assume time_t is signed.
9418 (select_wrapper): Remove; we now use pselect.
9419 (Fprocess_attributes): Now generates ns-resolution time stamps.
9421 * sysdep.c: Include utimens.h. Don't include utime.h
9422 or worry about struct utimbuf; gnulib does that for us now.
9423 (gettimeofday): Remove; gnulib provides a substitute.
9424 (make_timeval): New function.
9425 (set_file_times): Now sets ns-resolution time stamps.
9426 New arg FD; all uses changed.
9427 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9428 (system_process_attributes):
9429 Now returns ns-resolution time stamp. All uses changed.
9430 Check for time stamp overflow.
9432 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9433 provides a substitute now.
9435 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9436 since it guarantees struct timespec.
9437 (EMACS_TIME): Now struct timespec, so that we can support
9438 ns-resolution time stamps.
9439 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9440 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9441 (EMACS_USECS): Remove.
9442 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9443 so multiply the arg by 1000 before storing it.
9444 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9446 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9447 Port to ns-resolution time stamps.
9448 (EMACS_TIME_NEG_P): Remove; replaced by....
9449 (EMACS_TIME_SIGN): New macro.
9450 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9451 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
9452 (set_file_times, make_time, lisp_time_argument): Adjust signature.
9453 (make_timeval, make_lisp_time, decode_time_components): New decls.
9454 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9455 that it mishandled time_t overflow. You can't compare by subtracting!
9456 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9457 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9459 * term.c: Include <sys/time.h>.
9460 (timeval_to_Time): New function, for proper overflow wraparound.
9461 (term_mouse_position, term_mouse_click): Use it.
9463 * undo.c (record_first_change): Support higher-resolution time stamps
9465 (Fprimitive_undo): Use them when restoring time stamps.
9467 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9468 (w32_get_internal_run_time):
9469 Port to higher-resolution Emacs time stamps.
9470 (ltime): Now accepts single 64-bit integer, as that's more convenient
9473 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9475 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9476 for compatibility with pselect. Support ns-resolution time stamps.
9478 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9480 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9481 Check for time stamp overflow, and support ns-resolution time stamps.
9483 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9484 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9485 (timeval_subtract): Remove; no longer needed.
9486 (XTflash, XTring_bell, x_wait_for_event):
9487 Port to ns-resolution time stamps. Don't assume time_t is signed.
9489 2012-06-22 Chong Yidong <cyd@gnu.org>
9491 * xdisp.c (x_consider_frame_title): Revert last change.
9493 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9495 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9496 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9497 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9498 staticidx goes up to 1597 out of 1600 = 0x640.)
9500 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9502 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9503 Otherwise, the umask might be mistakenly 0 while handling input signals.
9505 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
9507 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

9512 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
9513 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
9514 access to `contents' member of Lisp_Vector objects with AREF and ASET
9517 2012-06-19 Chong Yidong <cyd@gnu.org>
9519 * frame.c (delete_frame): When selecting a frame on a different
9520 text terminal, do not alter the terminal's top-frame.

9523 frame's selected window and its terminal's top-frame.
9524 (unwind_format_mode_line): Restore them.
9525 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9527 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9528 since tty frames can be explicitly named.
9529 (prepare_menu_bars): Likewise.
9531 * term.c (Ftty_top_frame): New function.
9533 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9535 Port byte-code-meter to modern targets.
9536 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9537 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9538 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9539 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

9770 code works fine either way, and efficiency is not a concern here,
9771 as the union type is for debugging, not for production.
9772 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9773 Use an inline function on all platforms when using the union type,
9774 since this is simpler and 'static inline' can be used portably

9918 * doprnt.c (doprnt): Truncate multibyte char correctly.
9919 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9920 would mishandle a string argument "Xc" if X was a multibyte
9921 character of length 2: it would truncate after X's first byte
9922 rather than including all of X.

10005 and 'double' in a couple of places.
10007 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10009 * xdisp.c (handle_stop): Detect whether we have overlay strings
10010 loaded by testing it->current.overlay_string_index to be
10011 non-negative, instead of checking whether n_overlay_strings is
10012 positive. (Bug#11587)

10020 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10022 * search.c (search_buffer): Remove calls to
10023 r_alloc_inhibit_buffer_relocation, as it is now called by
10024 maybe_unify_char, which was the cause of relocation of buffer text
10027 2012-05-31 Eli Zaretskii <eliz@gnu.org>
10029 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10030 for the duration of call to load_charset, to avoid problems with
10031 callers of maybe_unify_char that access buffer text through C
10034 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
10035 decrement the inhibition flag, instead of just setting or
10038 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
10040 Remove obsolete '#define static' cruft.
10041 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
10042 This #undef was "temporary" in 2000; it is no longer needed
10043 now that '#define static' has gone away.
10044 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
10045 (gray_bitmap_bits): Remove; no longer needed.
10046 All uses replaced with definiens.
10047 * xterm.c: Include "bitmaps/gray.xbm".
10049 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10051 Clean up __executable_start, monstartup when --enable-profiling.
10052 The following changes affect the code only when profiling.
10053 * dispnew.c (__executable_start): Rename from safe_bcopy.
10054 Define only on platforms that need it.
10055 * emacs.c: Include <sys/gmon.h> when profiling.
10056 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10057 (__executable_start): Remove decl, since lisp.h does it now.
10058 (safe_bcopy): Remove decl; no longer has that name.
10059 (main): Coalesce #if into single bit of code, for simplicity.
10060 Cast pointers to uintptr_t, since standard libraries want integers
10062 * lisp.h (__executable_start): New decl.
10064 2012-05-31 Glenn Morris <rgm@gnu.org>
10066 * image.c (Fimagemagick_types): Doc fix.
10068 2012-05-30 Jim Meyering <meyering@redhat.com>
10070 * callproc.c (Fcall_process_region): Include directory component
10071 in mkstemp error message (Bug#11586).
10073 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10075 * alloc.c, lisp.h (make_pure_vector): Now static.
10077 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
10079 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
10080 Move to byte-run.el.
10081 (Fautoload): Do the hash-doc more carefully.
10082 * data.c (Fdefalias): Purify definition, except for keymaps.
10083 (Qdefun): Move from eval.c.
10084 * lisp.h (Qdefun): Remove.
10085 * lread.c (read1): Tiny simplification.
10087 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
10089 Do not create empty overlays with the evaporate property (Bug#9642).
10090 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10091 Bug#9642, but explicitly check that the buffer the overlay would
10092 be moved to is live and rearrange lines to make sure that errors
10093 will not put the overlay in an inconsistent state.
10094 (Fdelete_overlay): Cosmetics.
10096 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10098 * w32term.c (my_bring_window_to_top): New function.
10099 (x_raise_frame): Use handle returned by DeferWindowPos, which
10100 could be different from the original one.
10101 Call my_bring_window_to_top instead of my_set_foreground_window.
10104 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
10105 by calling BringWindowToTop.

10110 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10112 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10113 This avoids undefined behavior that might cause the eassert
10114 to not catch an out-of-range value.
10116 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10118 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10119 Update dependencies.
10121 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10123 * bidi.c (bidi_mirror_char): Fix last change.
10125 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
10127 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
10128 when referring to sectname field in printf format.
10130 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10132 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10133 Only r_alloc_inhibit_buffer_relocation needed to be added;
10134 the others were already declared.
10136 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10137 before checking whether it's out of range. Put the check inside
10139 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10141 2012-05-27 Ken Brown <kbrown@cornell.edu>
10143 * callproc.c (Fcall_process): Restore a line that was accidentally
10144 commented out in the 2011-02-13 change (bug#11547).
10146 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10148 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10149 defined on ralloc.c.
10151 * buffer.c [REL_ALLOC]: Remove prototypes of
10152 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10153 they are now on lisp.h.
10155 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10157 * search.c (search_buffer): Use it to inhibit relocation of buffer
10158 text while re_search_2 is doing its job, because re_search_2 is
10159 passed C pointers to buffer text. (Bug#11519)
10161 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10162 Update value to 24.
10164 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10165 state after an additional call to move_it_in_display_line_to, keep
10166 the values of it->max_ascent and it->max_descent found for the
10168 (pos_visible_p): Revert the comparison against bottom_y to what it
10169 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10172 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10174 Fix coding-related core dumps with gcc -ftrapv.
10175 The code was computing A - B, where A and B are pointers, and B is
10176 random garbage. This can lead to core dumps on platforms that
10177 have special pointer registers, and it also leads to core dumps on
10178 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10179 A - B only when B is initialized properly.
10180 * coding.c (coding_set_source, coding_set_destination): Return void.
10181 (coding_change_source, coding_change_destinations): New functions,
10182 with the old behaviors of coding_set_source and coding_set_destination.
10183 All callers that need an offset changed to use these new functions.
10185 2012-05-26 Glenn Morris <rgm@gnu.org>
10187 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
10189 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10191 Extend mouse support on W32 text-mode console.
10192 * xdisp.c (draw_row_with_mouse_face):
10193 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10195 * w32console.c: Include window.h.
10196 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10198 (initialize_w32_display): Initialize mouse-highlight data.
10200 * w32inevt.c: Include termchar.h and window.h.
10201 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10202 moves, call note_mouse_highlight. If help_echo changed, call
10203 gen_help_event to produce help-echo message in the echo area.
10204 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10207 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10209 * lread.c (read1): Simplify slightly to avoid an overflow warning
10210 with GCC 4.7.0 on x86-64.
10212 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10214 * bidi.c (bidi_mirror_char): Revert last change: an int is
10215 definitely wide enough here.
10217 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10219 Fix integer width and related bugs (Bug#9874).
10220 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
10221 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
10222 (string_bytes, check_sblock, allocate_string_data):
10223 (compact_small_strings, Fmake_bool_vector, make_string)
10224 (make_unibyte_string, make_multibyte_string)
10225 (make_string_from_bytes, make_specified_string)
10226 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10227 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10229 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10230 (allocate_pseudovector):
10231 Use int, not EMACS_INT, where int is wide enough.
10232 (inhibit_garbage_collection, Fgarbage_collect):
10233 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10234 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10235 int might not be wide enough.
10236 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10237 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10238 (bidi_at_paragraph_end, bidi_find_paragraph_start)
10239 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
10240 (bidi_level_of_next_char, bidi_move_to_visually_next):
10241 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10242 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
10243 (Fkill_buffer, Fset_buffer_major_mode)
10244 (advance_to_char_boundary, Fbuffer_swap_text)
10245 (Fset_buffer_multibyte, overlays_at, overlays_in)
10246 (overlay_touches_p, struct sortvec, record_overlay_string)
10247 (overlay_strings, recenter_overlay_lists)
10248 (adjust_overlays_for_insert, adjust_overlays_for_delete)
10249 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
10250 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
10251 (Foverlay_recenter, last_overlay_modification_hooks_used)
10252 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10253 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10254 (validate_region): Omit unnecessary test for b <= e,
10255 since that's guaranteed by the previous test.
10256 (adjust_overlays_for_delete): Avoid pos + length overflow.
10257 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10258 (report_overlay_modification):
10259 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10260 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10261 Omit pointer cast, which isn't needed anyway, and doesn't work
10262 after the EMACS_INT -> ptrdiff_t change.
10263 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10264 * buffer.h: Adjust decls to match defn changes elsewhere.
10265 (struct buffer_text, struct buffer):
10266 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10267 Use EMACS_INT, not int, where int might not be wide enough.
10268 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10269 not int, to avoid needless 32-bit limit on 64-bit hosts.
10270 (exec_byte_code): Use tighter memory-full test, one that checks
10271 for alloca overflow. Don't compute the address of the object just
10272 before an array, as that's not portable. Use EMACS_INT, not
10273 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10274 * callint.c (Fcall_interactively):
10275 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10276 * callproc.c (call_process_kill, Fcall_process):
10277 Don't assume pid_t fits into an Emacs fixnum.
10278 (call_process_cleanup, Fcall_process, child_setup):
10279 Don't assume pid_t fits into int.
10280 (call_process_cleanup, Fcall_process, delete_temp_file)
10281 (Fcall_process_region):
10282 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10283 (Fcall_process): Simplify handling of volatile integers.
10284 Use int, not EMACS_INT, where int will do.
10285 * casefiddle.c (casify_object, casify_region, operate_on_word)
10286 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10287 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10288 (casify_object): Avoid integer overflow when overallocating buffer.
10289 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10290 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10291 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10292 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10293 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10294 integers are now checked earlier. All uses replaced with XINT.
10296 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10297 For CCL_MapSingle, check that content and value are in int range.
10298 (ccl_driver, Fregister_code_conversion_map):
10299 Check that Vcode_version_map_vector is a vector.
10300 (resolve_symbol_ccl_program): Check that vector header is in range.
10301 Always copy the vector, so that we can check its contents reliably
10302 now rather than having to recheck each instruction as it's being
10303 executed. Check that vector words fit in 'int'.
10304 (ccl_get_compiled_code, Fregister_ccl_program)
10305 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10306 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10307 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10308 contents are in range.
10309 (Fccl_execute_on_string): Check that status is in range.
10310 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10311 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10312 Accept and return EMACS_INT, not int, because callers can pass values
10313 out of 'int' range.
10314 (c_string_width, strwidth, lisp_string_width, chars_in_text)
10315 (multibyte_chars_in_text, parse_str_as_multibyte)

10317 (str_as_unibyte, str_to_unibyte, string_count_byte8)
10318 (string_escape_byte8, Fget_byte):
10319 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10320 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10321 avoid mishandling large integers.
10322 * character.h: Adjust decls to match defn changes elsewhere.
10323 * charset.c (load_charset_map_from_file, find_charsets_in_text)
10324 (Ffind_charset_region):
10325 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10326 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
10327 (load_charset_map_from_vector, Fdefine_charset_internal):
10328 Don't assume fixnum fits in int.
10329 (load_charset_map_from_vector, Fmap_charset_chars):
10330 Remove now-unnecessary CHECK_NATNUMs.
10331 (Fdefine_charset_internal): Check ranges here, more carefully.
10332 Don't rely on undefined behavior with signed left shift overflow.
10333 Don't assume unsigned int fits into fixnum, or that fixnum fits
10334 into unsigned int. Don't require max_code to be a valid fixnum;
10335 that's not true for gb10830 4-byte on a 32-bit host. Allow
10336 invalid_code to be a cons, for the same reason. Require code_offset
10337 to be a character. Avoid int overflow if max_char is close
10339 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10340 this is intended anyway and avoids some undefined behavior.
10341 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10342 INDEX_TO_CODE_POINT, as that's what it expects.
10343 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10344 * charset.h (DECODE_CHAR): Return int, not unsigned;
10345 this is what was intended anyway, and it avoids undefined behavior.
10346 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10347 integer-overflow issues.
10348 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10349 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10350 where the argument is EMACS_INT, and this behavior is not intended.
10351 * chartab.c (Fmake_char_table, Fset_char_table_range)
10352 (uniprop_get_decoder, uniprop_get_encoder):
10353 Don't assume fixnum fits in int.
10354 * cmds.c (move_point): New function, that does the gist of
10355 Fforward_char and Fbackward_char, but does so while checking
10356 for integer overflow more accurately.
10357 (Fforward_char, Fbackward_char): Use it.
10358 (Fforward_line, Fend_of_line, internal_self_insert)
10359 (internal_self_insert):
10360 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10361 Fix a FIXME, by checking for integer overflow when calculating
10362 target_clm and actual_clm.

10394 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10395 (consume_chars): Rewrite to not calculate an address outside buffer.
10396 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
10397 Don't access memory outside of the args array.
10398 (Fdefine_coding_system_internal): Check for charset-id overflow.
10399 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
10400 result of ENCODE_CHAR.
10401 * coding.h: Adjust decls to match defn changes elsewhere.
10402 (struct coding_system):

11090 2012-05-21 Ken Brown <kbrown@cornell.edu>
11092 * xgselect.c (xg_select): Fix first argument in call to 'select'
11095 2012-05-20 Ken Brown <kbrown@cornell.edu>
11097 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
11098 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
11100 2012-05-19 Ken Brown <kbrown@cornell.edu>
11102 * xfns.c (x_in_use): Remove `static' qualifier.
11103 * xterm.h (x_in_use): Declare.
11104 * xgselect.c: Include xterm.h.
11105 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
11106 and `display_arg' (bug#9754).
11108 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
11110 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
11112 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
11113 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
11115 2012-05-18 Eli Zaretskii <eliz@gnu.org>
11117 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
11119 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
11120 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11122 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11123 reference to image_cache->refcount.
11124 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11126 2012-05-17 Juri Linkov <juri@jurta.org>
11128 * search.c (Fword_search_regexp, Fword_search_backward)
11129 (Fword_search_forward, Fword_search_backward_lax)
11130 (Fword_search_forward_lax): Move functions to isearch.el
11131 (bug#10145, bug#11381).
11133 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11135 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11137 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11139 * lread.c (init_obarray): Declare Qt and Qnil as special.
11141 2012-05-14 Glenn Morris <rgm@gnu.org>
11143 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11144 Put "libexec" before "bin", for the sake of init_callproc_1.
11146 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11148 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11150 * unexaix.c: Port to more-recent AIX compilers.
11151 (report_error, report_error_1, make_hdr, copy_sym)
11152 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11153 Make arguments const char *, not char *, to avoid violations of C
11154 standard and to fix some AIX warnings reported by Gilles Pion.
11156 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11158 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11159 already have overlays loaded.
11160 (handle_single_display_spec): Before returning without displaying
11161 fringe bitmap, synchronize the bidi iterator with the main display
11162 iterator, by calling iterate_out_of_display_property.
11163 (iterate_out_of_display_property): Detect buffer iteration by
11164 testing that it->string is a Lisp string.
11165 (get_next_display_element): When the current object is exhausted,
11166 and there's something on it->stack, call set_iterator_to_next to
11167 proceed with what's on the stack, instead of returning zero.
11168 (set_iterator_to_next): If called at the end of a Lisp string,
11169 proceed to consider_string_end without incrementing string
11170 position. Don't increment display vector index past the end of
11171 the display vector. (Bug#11417)
11172 (pos_visible_p): Don't report a position visible when move_it_to
11173 stopped at the last line of window, which happens to be scanned
11174 backwards by the bidi iteration. (Bug#11464)
11176 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11178 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11179 and right-margin display specs even if the spec is invalid or we
11180 are on a TTY, and thus unable to display on the fringes.
11181 That's because the text with the property will not be displayed anyway,
11182 so we need to signal to the caller that this is a "replacing"
11183 display spec. This fixes display when the spec is invalid or we
11186 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11188 * unexaix.c (make_hdr): Fix typo in prototype.
11189 This bug broke the build on AIX. Problem reported by Gilles Pion.
11191 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11193 * keyboard.c (kbd_buffer_get_event): Read special events also in
11194 batch mode. (Bug#11415)
11196 2012-05-12 Glenn Morris <rgm@gnu.org>
11198 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11200 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11202 * lisp.mk (lisp): Add newcomment.elc.
11204 2012-05-12 Glenn Morris <rgm@gnu.org>
11206 * Makefile.in (MKDIR_P): New, set by configure.
11207 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11209 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11211 Remove unused function hourglass_started.
11212 * dispextern.h (hourglass_started):
11213 * w32fns.c (hourglass_started):
11214 * xdisp.c (hourglass_started): Remove.
11216 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11218 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11219 Update dependencies.
11221 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11223 * xgselect.c (xg_select): Put maxfds+1 into a var.
11224 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11226 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11228 2012-05-10 Dave Abrahams <dave@boostpro.com>
11230 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11231 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11233 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11235 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11236 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11237 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11238 Initialize xd_registered_buses.
11240 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11242 Untag more efficiently if USE_LSB_TAG.
11243 This is based on a proposal by YAMAMOTO Mitsuharu in
11244 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11245 For an admittedly artificial (nth 8000 longlist) benchmark on
11246 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11247 Emacs's overall text size by 1%.
11248 * lisp.h (XUNTAG): New macro.
11249 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11250 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11251 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11252 * eval.c (Fautoload):
11253 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11254 * frame.h (XFRAME): Use XUNTAG.
11256 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11257 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11258 Remove unportable assumptions about print widths of types like
11260 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11261 intptr_t when converting between pointer and integer, to avoid GCC
11262 warnings about wrong width.
11264 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11266 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11267 stack for each reader_thread, instead of defaulting to 8MB
11268 determined by the linker. This avoids failures in creating
11269 subprocesses on Windows 7, see the discussion in this thread:
11270 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11272 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11274 Fix up display of the *Minibuf-0* buffer in the mini window.
11275 * keyboard.c (read_char): Don't clear the echo area if there's no
11277 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11278 contents of *Minibuf-0*) if there's no message displayed in its stead.
11280 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11282 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11285 2012-05-06 Chong Yidong <cyd@gnu.org>
11287 * lisp.mk (lisp): Update.
11289 2012-05-05 Jim Meyering <meyering@redhat.com>
11291 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11293 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11295 * data.c (PUT_ERROR): New macro.
11296 (syms_of_data): Use it. Add new error type `user-error'.
11297 * undo.c (user_error): New function.
11298 (Fprimitive_undo): Use it.
11299 * print.c (print_error_message): Adjust print style for `user-error'.
11300 * keyboard.c (user_error): New function.
11301 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11303 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11305 Do not limit current-time-string to years 1000..9999.
11306 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11307 (Fcurrent_time_string): Support any year that is supported by the
11308 underlying localtime representation. Don't use asctime, as it
11309 has undefined behavior for years outside the range -999..9999.
11311 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11313 Fix race conditions involving setenv, gmtime, localtime, asctime.
11314 Without this fix, interrupts could mess up code that uses these
11315 nonreentrant functions, since setting TZ invalidates existing
11316 tm_zone or tzname values, and since most of these functions return
11317 pointers to static storage.
11318 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11319 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11320 Grow the critical sections to include not just invoking
11321 localtime/gmtime, but also accessing these functions' results
11322 including their tm_zone values if any, and any related TZ setting.
11323 (format_time_string): Last arg is now struct tm *, not struct tm **,
11324 so that the struct tm is saved in the critical section.
11325 All callers changed. Simplify allocation of initial buffer, partly
11326 motivated by the fact that memory allocation needs to be outside
11327 the critical section.
11329 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11331 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11332 with RESET_INTERVAL.
11334 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11335 Remove duplicated buffer name initialization.
11337 2012-05-02 Jim Meyering <jim@meyering.net>
11339 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11341 * xfns.c (x_window): Use xstrdup (Bug#11375).
11343 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11345 * xdisp.c (pos_visible_p): If already at a newline from the
11346 display string before the 'while' loop, don't walk back the glyphs
11347 from it3.glyph_row. Solves assertion violation when the display
11348 string begins with a newline (egg.el). (Bug#11367)
11350 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11352 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11355 2012-05-01 Glenn Morris <rgm@gnu.org>
11357 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11358 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11359 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11360 All were removed before 23.1.
11362 * dispnew.c: Remove HAVE_LIBNCURSES test;
11363 it is always true on relevant platforms.
11365 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11366 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11368 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11370 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11372 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11373 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11376 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11378 Do not avoid creating empty evaporating overlays (Bug#9642).
11379 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11380 That is, do not delete an evaporating overlay if it becomes
11381 empty after its bounds are adjusted to fit within its buffer.
11382 This fix caused other problems, and I'm reverting it until we get
11383 to the bottom of them.
11385 2012-04-27 Chong Yidong <cyd@gnu.org>
11387 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11389 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11391 * xdisp.c (pos_visible_p): If the window start position is beyond
11392 ZV, start the display from buffer beginning. Prevents assertion
11393 violation in init_iterator when the minibuffer window is scrolled
11394 via the scroll bar.
11396 * window.c (window_scroll_pixel_based): Likewise.
11398 2012-04-27 Chong Yidong <cyd@gnu.org>
11400 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11402 2012-04-27 Glenn Morris <rgm@gnu.org>
11404 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11405 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11407 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11409 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11410 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11412 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11414 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11415 display element, check also the underlying string or buffer
11416 character. (Bug#11341)
11418 * w32menu.c: Include w32heap.h.
11419 (add_menu_item): If the call to AppendMenuW (via
11420 unicode_append_menu) fails, disable Unicode menus only if we are
11421 running on Windows 9X/Me.
11423 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11425 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11426 (xgetint): Add missing shift for LSB tags.
11428 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11430 * keyboard.c (read_char): Don't wipe echo area for select window
11431 events: These might get delayed via `mouse-autoselect-window'
11434 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11436 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11437 manipulation of :loaded-from data.
11439 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11441 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11442 now a cons (bug#11311).
11444 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11446 Do not create empty overlays with the evaporate property (Bug#9642).
11447 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11448 if it becomes empty after its bounds are adjusted to fit within
11449 its buffer. Without this fix, in a nonempty buffer (let ((o
11450 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11451 yields an empty overlay that has the evaporate property, which is
11452 not supposed to happen.
11454 Fix minor GTK3 problems found by static checking.
11455 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11456 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11457 (struct _EmacsFixedClass, emacs_fixed_get_type):
11458 Move decls here from emacsgtkfixed.h, since they needn't be public.
11459 (emacs_fixed_get_type): Now static.
11460 (emacs_fixed_class_init): Omit unused local.
11461 (emacs_fixed_child_type): Remove; unused.
11462 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11463 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11464 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11465 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11466 (EMACS_FIXED_GET_CLASS): Remove; unused.
11467 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11469 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11470 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11472 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11474 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11475 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11476 (__malloc_size_t, __malloc_ptrdiff_t):
11477 Remove. All uses removed, replaced by the definiens if needed,
11478 since we can assume C89 or better now.
11479 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

11487 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11488 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11489 Define using prototypes, not old style.
11490 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11491 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11492 (align): Don't assume that signed integer overflow wraps around.
11493 Omit unused local var.
11494 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
11495 (_free_internal_nolock, memalign, mallochook, reallochook):
11496 Omit no-longer-needed casts.
11497 (valloc): Use getpagesize, not __getpagesize.
11498 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11499 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11501 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11503 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11505 Move functions from C to Lisp. Make non-blocking method calls
11506 the default. Implement further D-Bus standard interfaces.
11508 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

11521 (XD_DBUS_VALIDATE_BUS_NAME, XD_DBUS_VALIDATE_PATH)
11522 (XD_DBUS_VALIDATE_INTERFACE, XD_DBUS_VALIDATE_MEMBER): New macros.
11523 (XD_CHECK_DBUS_SERIAL): Rename from CHECK_DBUS_SERIAL_GET_SERIAL.
11524 (xd_signature, xd_append_arg): Allow float for integer types.
11525 (xd_get_connection_references): New function.
11526 (xd_get_connection_address): Rename from xd_initialize.

11565 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
11567 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11569 * sysdep.c [__FreeBSD__]: Minor cleanups.
11570 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11571 Use Emacs indenting style more consistently. Avoid some casts.

11576 * sysdep.c (list_system_processes, system_process_attributes):
11577 Add implementation for FreeBSD (Bug#5243).

11583 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
11585 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
11586 It is never used otherwise.
11588 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
11590 * print.c (print_preprocess): Only check print_depth if print-circle
11592 (print_object): Check for cycles even when print-circle is nil and
11593 print-gensym is t, but only check print_depth if print-circle is nil.

11597 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11598 set the status to "failed" and ensure that sentinel is run.
11600 2012-04-20 Glenn Morris <rgm@gnu.org>
11602 * process.c (Fset_process_inherit_coding_system_flag)
11603 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

11631 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
11632 -Wunused-result, -Wunused-variable. This should go away once
11633 the Emacs and Gnulib regex code is merged.
11634 (xmalloc, xrealloc): Now static.
11636 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

11653 New extern decls, to avoid calling undeclared functions.
11654 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11655 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11656 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11657 (NEED_MEM_INSERT): New macro.
11658 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11659 Remove one incorrect comment and fix another.

11674 Remove decls. This fixes an "It stinks!".
11676 * alloc.c (which_symbols): Fix alignment issue / type clash.
11678 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11680 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
11681 (struct Lisp_Misc_Any): Likewise.
11682 (struct Lisp_Free): Likewise.
11683 * alloc.c (union aligned_Lisp_Symbol): Define.

11695 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11696 * s/netbsd.h, s/sol2-6.h:
11697 Remove definition of GC_MARK_STACK, since the default now works.
11698 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

11700 no longer the default.
11701 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11703 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11705 * lread.c (lisp_file_lexically_bound_p):

11724 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11726 2012-04-11 Daniel Colascione <dancol@dancol.org>
11728 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11729 against is gone. It's better to use vfork now so that when Cygwin
11730 gains a new, working vfork, we use it automatically (bug#10398).
11732 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
11734 * window.c (save_window_save): Obey window-point-insertion-type.

11752 * w32.c (w32_delayed_load): Record the full path of the library
11753 being loaded (bug#10424).
11755 2012-04-09 Glenn Morris <rgm@gnu.org>
11757 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11758 not just in the obarray, before snarfing them. (Bug#11036)

11775 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11776 attempts per process (connection).
11778 2012-04-09 Chong Yidong <cyd@gnu.org>
11780 * eval.c (Fuser_variable_p, user_variable_p_eh)

11785 * minibuf.c (Fread_variable): Callers changed.
11787 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11789 * xdisp.c (set_cursor_from_row): If the display string appears in
11790 the buffer at position that is closer to point than the position
11791 after the display string, display the cursor on the first glyph of
11792 the display string. Fixes cursor display when a 'display' text
11793 property immediately follows invisible text. (Bug#11094)
11795 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11797 composite.c: use 'double' consistently
11798 * composite.c (get_composition_id): Use 'double' consistently
11799 instead of converting 'float' to 'double' and vice versa; this is
11800 easier to understand and avoids a GCC warning.
11802 2012-04-09 Glenn Morris <rgm@gnu.org>
11804 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11805 preparation for dumping it with emacs. (Bug#4789)

11827 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11828 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11829 objects, as mark_maybe_pointer will catch them otherwise.

11847 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11848 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11849 [!WINDOWSNT]: New macros.
11850 (init_libxml2_functions, libxml2_loaded_p): New functions.
11851 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11852 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11853 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11854 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11856 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11857 Call init_libxml2_functions before calling libxml2 functions.
11858 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11860 * emacs.c: Don't include libxml/parser.h.
11861 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11862 xmlCleanupParser directly.
11864 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
11866 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11868 * indent.c (Fvertical_motion): If there is a display string at
11869 point, use it.vpos to compute how many lines to backtrack after
11870 move_it_to point. (Bug#11133)
11872 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11874 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11875 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11876 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11877 macros related to unification of CJK characters. For the details,
11878 see the discussion following the message here:
11879 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11881 2012-04-04 Chong Yidong <cyd@gnu.org>
11883 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11885 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11887 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

11895 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11897 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11898 position we get to after a call to move_it_to fails the
11899 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11900 only if we wind up in a string from display property. (Bug#11063)
11902 * window.c (Fdelete_other_windows_internal): Invalidate the row
11903 and column information about mouse highlight, so that redisplay
11904 restores it after reallocating the glyph matrices. (Bug#7464)
11906 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11907 string comes from a `display' text property, use the buffer
11908 position of that property as if we actually saw that position in
11910 (move_it_by_lines): Remove the assertion that
11911 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11912 violated when there's a before-string at the beginning of a line.
11915 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11917 * xdisp.c (append_space_for_newline): If the default face was
11918 remapped, use the remapped face for the appended newline.
11919 (extend_face_to_end_of_line): Use the remapped default face for
11920 extending the face to the end of the line.
11921 (display_line): Call extend_face_to_end_of_line when the default
11922 face was remapped. (Bug#11068)
11924 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11926 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
11928 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

11944 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11945 (command_loop_1): Use it; inhibit selection update for

11950 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11952 2012-03-25 Kenichi Handa <handa@m17n.org>
11954 * dispextern.h (struct glyph): Change the bit length of
11955 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11957 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11959 * s/ms-w32.h (tzname): Include time.h before redirecting to

11968 !SYNC_INPUT. (Bug#11080)
11970 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11972 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11973 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11974 when fetching a multibyte character consumes more bytes than
11975 CHAR_BYTES returns, due to unification of CJK characters in
11976 string_char. (Bug#11073)
11978 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11980 * process.c (wait_reading_process_output): Handle pty disconnect

12010 it fit in a valid range (Bug#11003).
12012 2012-03-18 Eli Zaretskii <eliz@gnu.org>
12014 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
12015 that is not from display property, accept the row as a "cursor
12016 row" if one of the string's character has a non-nil `cursor'
12017 property. Fixes cursor positioning when there are newlines in
12018 overlay strings, e.g. in icomplete.el. (Bug#11035)
12020 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

12054 2012-03-03 Glenn Morris <rgm@gnu.org>
12056 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12058 2012-03-02 Eli Zaretskii <eliz@gnu.org>

12074 push_it before setting up the iterator for the first overlay
12075 string, even if we have an empty string loaded.
12076 (next_overlay_string): If there's an empty string on the iterator
12077 stack, pop the stack. (Bug#10903)
12079 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12081 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12082 Suggested by Stefan Monnier in
12083 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12084 * alloc.c (widen_to_Lisp_Object): New static function.
12085 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12086 and widening them to Lisp_Objects. This would work even if
12087 USE_LSB_TAG is defined and wide integers are used, which might
12088 happen in a future version of Emacs.
12090 2012-02-25 Chong Yidong <cyd@gnu.org>
12092 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

12097 before saving to clipboard manager.
12099 2012-02-24 Chong Yidong <cyd@gnu.org>
12101 * keyboard.c (process_special_events): Handle all X selection
12102 requests in kbd_buffer, not just the next one (Bug#8869).
12104 2012-02-23 Chong Yidong <cyd@gnu.org>
12106 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12107 call when setting menu-bar-lines and tool-bar-lines parameters.
12108 (unwind_create_frame_1): New helper function.

12129 when computing $valmask.
12131 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12132 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12133 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12134 It's useless in that case, and it can cause problems on hosts
12135 that allocate halves of EMACS_INT values separately.
12136 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12137 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12138 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12139 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12140 it avoids undefined behavior on hosts where shifting right by more
12141 than the word width has undefined behavior.
12143 2012-02-19 Chong Yidong <cyd@gnu.org>
12145 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12146 (Funhandled_file_name_directory, Ffile_name_as_directory)
12147 (Fdirectory_file_name, Fexpand_file_name)
12148 (Fsubstitute_in_file_name): Protect against invalid file handler
12149 return values (Bug#10845).

12165 2012-02-15 Chong Yidong <cyd@gnu.org>
12167 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12168 marked as special. Also, starting docstrings with * is obsolete.

12183 2012-02-12 Chong Yidong <cyd@gnu.org>
12185 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12186 as that creates a dangerous corner case.
12188 * window.c (Fdelete_window_internal): Invalidate the mouse
12189 highlight (Bug#9904).
12191 2012-02-12 Glenn Morris <rgm@gnu.org>

12197 (Fx_disown_selection_internal, Fx_selection_exists_p)
12198 (Fx_selection_owner_p, Fx_get_selection_internal):
12199 Sync docs and argument specs with the xselect.c versions.
12201 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

12221 2012-02-07 Chong Yidong <cyd@gnu.org>
12223 * buffer.c (Fbuffer_local_variables)
12224 (buffer_lisp_local_variables): Handle unbound vars correctly;
12225 don't let Qunbound leak into Lisp.
12227 2012-02-07 Glenn Morris <rgm@gnu.org>
12229 * image.c (Fimagemagick_types): Doc fix.
12231 * image.c (imagemagick-render-type): Change it from a lisp object
12232 to an integer. Move the doc here from the lisp manual.

12251 * w32.c (get_emacs_configuration_options):
12252 Include --enable-checking, if specified, in the return value.

12266 Handle overflow when computing char display width (Bug#9496).
12267 * character.c (char_width): Return EMACS_INT, not int.
12268 (char_width, c_string_width): Check for overflow when
12269 computing the width; this is possible now that individual
12270 characters can have unbounded width. Problem introduced
12271 by merge from Emacs 23 on 2012-01-19.

12295 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
12297 (x_produce_glyphs): If the component of a composition is a null
12298 string, set it->pixel_width to 1 to avoid zero-width glyph.

12302 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
12303 first 2 arguments are identical. This makes inserting large
12304 output from a subprocess an order of magnitude faster on
12305 MS-Windows, where all sbrk'ed memory is always contiguous.
12307 2012-01-31 Glenn Morris <rgm@gnu.org>

12400 Update template values to be closer to their typical values these days.
12402 2012-01-09 Eli Zaretskii <eliz@gnu.org>
12404 * xdisp.c (rows_from_pos_range): Accept additional argument
12405 DISP_STRING, and accept any glyph in a row whose object is that
12406 string as eligible for mouse highlight. Fixes mouse highlight of
12407 display strings from overlays. (Bug#10464)
12409 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
12411 emacs: fix an auto-save permissions race condition (Bug#10400)

12413 (Fmake_directory_internal): Use it.
12414 (do_auto_save_make_dir): Set it, instead of invoking chmod after

12418 (Fdo_auto_save): Catch all errors, not just file errors, so
12419 that the var is always cleared.

12758 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12759 verifies glyph row's hash code--we have just reallocated the

12920 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
12921 Otherwise, valgrind does not work on some platforms.
12922 Problem reported by Andreas Schwab in
12923 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
12924 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12925 is set, removing the need for VIRT_ADDRESS_VARIES.
12926 (PURE_P): Use a more-efficient implementation that needs just one
12927 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
12928 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
12929 to 4 (xorl, subq, cmpq, setbe).
12930 * alloc.c (pure): Always extern now, since that's the
12931 VIRT_ADDR_VARIES behavior.
12932 (PURE_POINTER_P): Use a single comparison, not two, for
12933 consistency with the new puresize.h.
12934 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

13395 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
13397 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
13399 2011-10-28 Eli Zaretskii <eliz@gnu.org>
13401 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
13402 <oslsachem@gmail.com> for helping to debug this.
13404 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
13405 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
13406 (g_b_init_get_glyph_outline_w): New static variables.
13407 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
13408 (GetGlyphOutlineW_Proc): New typedefs.
13409 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
13410 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
13412 (w32font_open_internal, compute_metrics):
13413 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13414 instead of calling the "wide" APIs directly.
13416 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
13418 * w32.h (syms_of_w32font): Add prototype.
13420 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13422 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
13423 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
13424 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
13425 (Fmove_to_window_line): Doc fix.
13427 2011-10-27 Chong Yidong <cyd@gnu.org>
13429 * process.c (make_process): Set gnutls_state to NULL.
13431 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13432 non-NULL, regardless of GNUTLS_INITSTAGE.
13433 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13434 an error. Set process slots as soon as we allocate them.
13436 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13438 2011-10-27 Chong Yidong <cyd@gnu.org>
13440 * gnutls.c (emacs_gnutls_deinit): New function.
13441 Deallocate credentials structures as well as calling gnutls_deinit.
13442 (Fgnutls_deinit, Fgnutls_boot): Use it.
13444 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13445 (deactivate_process): Call emacs_gnutls_deinit.
13447 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13449 * image.c (x_create_x_image_and_pixmap):
13450 * w32.c (sys_rename, w32_delayed_load):
13451 * w32font.c (fill_in_logfont):
13452 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13454 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13456 * w32fns.c (w32_default_color_map): New function,
13457 extracted from Fw32_default_color_map.
13458 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13460 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13462 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13464 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13466 * keyboard.c (test_undefined): New function (bug#9751).
13467 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13469 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13471 * sysdep.c (init_sys_modes): Fix the check for the controlling
13472 terminal (Bug#6649).
13474 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13476 * dispextern.h (struct bidi_it): New member next_en_type.
13478 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13479 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13480 current character, check also for next_en_type being WEAK_EN.
13481 (bidi_resolve_weak): Don't enter the expensive loop if the current
13482 position is before next_en_pos. Record the bidi type of the first
13483 non-ET, non-BN character we find, in addition to its position.
13484 (bidi_level_of_next_char): Invalidate next_en_type when
13485 next_en_pos is over-stepped.
13487 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13489 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13490 * editfns.c: Rewrite current-time-zone so that it invokes
13491 the equivalent of (format-time-string "%Z") to get the time zone name.
13492 This fixes a bug when the time zone name contains characters that
13493 need converting from the system time locale to Emacs internal format.
13494 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13495 that patch fixed format-time-string to do the conversion, but
13496 I forgot to fix current-time-zone.
13497 (format_time_string): New function, containing most of
13498 what Fformat_time_string used to contain.
13499 (Fformat_time_string): Rewrite in terms of format_time_string.
13500 This doesn't change this function's behavior.
13501 (current-time-zone): Rewrite to use format_time_string.
13502 This fixes the bug reported by Michael Schierl in
13503 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13504 Jason Rumney's 2007-06-07 change worked around this bug, but
13506 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13508 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13510 * xdisp.c (start_display): If the character at POS is displayed
13511 via a display vector, reset IT->current.dpvec_index to zero.
13512 (try_window_reusing_current_matrix): If a line ends in a display
13513 vector or the next line starts in a display vector, continue
13514 redrawing the window even though the character position of
13515 start_row was reached.
13518 2011-10-18 Chong Yidong <cyd@gnu.org>
13520 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13521 with nobreak-char-display too.
13523 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13525 Fix part 3 of bug#9771.
13526 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13527 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13528 non-neutral characters if the current character is a paragraph
13529 separator (a.k.a. Newline). This avoids running the same
13530 expensive loop twice, once when we consume the preceding newline
13531 and the other time when the line actually needs to be displayed.
13532 Avoid the loop when we see neutrals on the base embedding level
13533 following a character whose directionality is the same as the
13534 paragraph's. This avoids running the expensive loop when a line
13535 ends in a long sequence of neutrals, like control characters.
13536 Add assertion against STRONG_AL type. Slightly rearrange code
13537 that determines the type of a neutral given the first non-neutral
13539 (bidi_level_of_next_char): Set next_en_pos to zero when
13540 invalidating its info.
13542 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13544 * xdisp.c (push_display_prop): Determine whether to record string
13545 or buffer position by IT->string, not by IT->method. Allow
13546 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13547 (move_it_vertically_backward): Don't look for character position
13548 immediately after the newline when in a continuation line.
13551 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13553 * window.c (coordinates_in_window): Rewrite and delabelize
13554 vertical border check. (Bug#5357) (Bug#9618)
13556 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13558 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13559 errors in XSetWindowBorder (bug#9310).
13561 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13563 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13564 avoid crash when xmalloc overrun checking is enabled.
13566 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13568 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13569 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13570 cursor motion with <left> and <right> arrow keys.
13572 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13573 some callers set that themselves.
13575 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13577 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13578 display string and the previous row comes from the same string and
13579 is empty. (Bug#9739) (Bug#9738)
13581 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13583 * doc.c (get_doc_string): Encode file name (bug#9735).
13585 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13587 * bidi.c (bidi_level_of_next_char):
13588 * xdisp.c (get_visually_first_element): Remove old incorrect
13589 comments regarding the Unicode Line Separator character.
13591 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13593 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13595 * alloc.c (Fgc_status): Do not access beyond zombies array
13596 boundary if nzombies > MAX_ZOMBIES.
13597 * alloc.c (dump_zombies): Add missing format specifier.
13599 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13601 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13602 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13604 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13605 Some packages use them to denote characters with modifiers.
13607 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13609 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13610 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13611 matching a pp-number. Rename parameter var to var1.
13613 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13615 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13617 2011-10-08 Glenn Morris <rgm@gnu.org>
13619 * callint.c (Fcall_interactively): Give a more explicit error for the
13620 'c' case with a non-character input. (Bug#8479)
13622 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13624 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13626 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13627 lines that are hscrolled on the left.
13629 * dispnew.c (buffer_posn_from_coords): Account for a possible
13630 presence of header-line. (Bug#4426)
13632 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13634 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13635 Don't advertise functionality which we discourage or doesn't work.
13637 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13639 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13640 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13641 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13642 this makes Emacs dump core during garbage collection on rare
13643 occasions. sizeof is obviously inferior to offsetof here, so
13644 stick with offsetof.
13645 (GC_POINTER_ALIGNMENT): New macro.
13646 (mark_memory): Omit 3rd (offset) arg; caller changed.
13647 Don't assume EMACS_INT alignment is the same as pointer alignment.
13649 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13651 * keyboard.c (read_key_sequence_remapped): New var.
13652 (read_key_sequence): Compute remapping in the right buffer.
13653 (command_loop_1): Use read_key_sequence's remapping directly.
13655 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13657 * dired.c (file_name_completion): Don't expand file name.
13658 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13659 before checking file name handler.
13661 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13662 they've been requested explicitly (bug#9591).
13664 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13666 * keymap.c (Fsingle_key_description): Use make_specified_string
13667 instead of build_string to build string from push_key_description.
13670 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13672 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13673 This fixes a Y2038 bug on 64-bit hosts.
13674 * buffer.c (reset_buffer):
13675 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13676 (Fclear_buffer_auto_save_failure):
13677 Use 0, not -1, to represent an unset failure time, since time_t
13678 might not be signed.
13680 Remove dependency on glibc malloc internals.
13681 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13682 Move back here from lisp.h, but with their new implementations.
13683 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13684 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13685 * charset.c (charset_table_init): New static var.
13686 (syms_of_charset): Use it instead of xmalloc. This removes a
13687 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13688 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13689 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13690 Move back to alloc.c.
13691 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13692 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13694 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13696 * nsterm.m (windowDidResize): Call x_set_window_size only when
13697 ns_in_resize is true. Otherwise set pixelwidth/height and
13698 call change_frame_size (Bug#9628).
13700 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13702 Port --enable-checking=all to Fedora 14 x86-64.
13703 * charset.c (syms_of_charset): Also account for glibc malloc's
13704 internal overhead when calculating the initial malloc maximum.
13706 Port --enable-checking=all to Fedora 14 x86.
13707 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13709 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13710 (overrun_check_realloc, overrun_check_free):
13711 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13712 That way, xmalloc returns a properly-aligned pointer even if
13713 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13714 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13715 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13716 into account when calculating the initial malloc maximum.
13717 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13718 Move here from alloc.c, so that charset.c can use it too.
13719 Properly align; the old code wasn't right for common 32-bit hosts
13720 when configured with --enable-checking=all.
13721 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13722 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13724 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13726 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13729 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13731 * xdisp.c (compute_display_string_end): If there's no display
13732 string at CHARPOS, return -1.
13734 * bidi.c (bidi_fetch_char): When compute_display_string_end
13735 returns a negative value, treat the character as a normal
13736 character not covered by a display string. (Bug#9624)
13738 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13740 * lread.c (Fread_from_string): Fix typo in docstring.
13742 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13744 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13745 newline, reseat the iterator instead of bidi-iterating there one
13746 character at a time. (Bug#9610)
13747 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13748 TO_CHARPOS if the bidi iterator is at base embedding level.
13750 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13752 * lread.c (readevalloop): Use correct code for NBSP.
13753 (read1): Likewise. (Bug#9608)
13755 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13757 * dbusbind.c (Fdbus_register_signal): When service is not
13758 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13760 2011-09-25 Glenn Morris <rgm@gnu.org>
13762 * buffer.c (truncate-lines): Doc fix.
13764 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13766 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13767 (Fset_window_next_buffers): Doc fix.
13769 2011-09-24 Glenn Morris <rgm@gnu.org>
13771 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13773 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13775 Fix minor problems found by static checking.
13776 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13777 * indent.c (Fvertical_motion): Fix == vs = typo.
13779 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13781 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13782 Default value is now t. Doc fix.
13784 * indent.c (Fvertical_motion): Compute and apply the overshoot
13785 logic when moving up, not only when moving down. Fix the
13786 confusing name and values of the it_overshoot_expected variable;
13787 logic changes accordingly. (Bug#9254) (Bug#9549)
13789 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13790 CHARPOS is covered by a display string which includes newlines.
13791 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13792 is covered by a display string with embedded newlines.
13794 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13796 * dbusbind.c (Fdbus_register_signal): Add match rule to
13797 Vdbus_registered_objects_table. (Bug#9581)
13798 (Fdbus_register_method, Vdbus_registered_objects_table):
13801 2011-09-24 Jim Meyering <meyering@redhat.com>
13803 do not ignore write error for any output size
13804 The previous change was incomplete.
13805 While it makes emacs --batch detect the vast majority of stdout
13806 write failures, errors were still ignored whenever the output size is
13807 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13808 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13809 && echo FAIL: ignored write error
13810 FAIL: ignored write error
13811 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13812 && echo FAIL: ignored write error
13813 FAIL: ignored write error
13814 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13816 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13818 * emacs.c (Fkill_emacs): In noninteractive mode exit
13819 non-successfully if a write error occurred on stdout. (Bug#9574)
13821 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13823 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13826 * dispextern.h (struct it): Update the comment documenting what
13829 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13831 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13832 a display string, extend search for cursor position to end of row.
13833 (find_row_edges): If the row ends in a newline from a display
13834 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13835 Handle the case of a display string with multiple newlines.
13836 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13837 non-empty line. Fixes confusing cursor motion with arrow keys at
13838 the beginning of a line that starts with whitespace.
13840 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13842 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13845 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13847 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13848 boolean (Bug#9154).
13850 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13852 * xdisp.c (display_line): Record maximum and minimum buffer
13853 positions even if no glyphs were produced (e.g., by a zero-width
13854 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13855 buffer positions that will be removed from the glyph row because
13857 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13858 column is beyond frame width: don't subtract 1 "pixel" when
13859 computing width of the stretch.
13860 (reseat_at_next_visible_line_start): Undo the change made on
13861 2011-09-17 that saved paragraph information and restored it after
13862 the call to `reseat'. (Bug#9545)
13864 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13866 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13867 and turn window cursor on if cleared (Bug#9415).
13869 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13871 * search.c (boyer_moore): Take unibyte characters from pattern
13872 literally. (Bug#9458)
13874 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13876 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13878 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13880 Fix minor problem found by static checking.
13881 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13882 initialized, to pacify gcc -Wuninitialized.
13884 * fileio.c: Report proper errno when syscall falls.
13885 (Finsert_file_contents): Save and restore errno,
13886 so that report_file_error outputs the correct diagnostic.
13887 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13889 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13891 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13893 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13895 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13896 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13898 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13900 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13901 about the current paragraph and restore it after the call to reseat.
13903 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13904 (bidi_find_paragraph_start): Search back for paragraph beginning
13905 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13906 (bidi_move_to_visually_next): Only trigger paragraph-related
13907 computations when the last character is a newline or at EOB, not
13908 just any NEUTRAL_B. (Bug#9470)
13910 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13911 truncated lines if point is covered by a display string. (Bug#9524)
13913 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13915 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13916 (cons_to_x_long): New function.
13917 (lisp_data_to_selection_data): Use it. Correct the test for
13918 short-versus-long data; it was negated. Break out of vector
13919 loop, for efficiency, when a long datum is discovered.
13921 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13923 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13925 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13927 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13928 GCC PR/17406) by declaring this function with external scope.
13930 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13932 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13933 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13935 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13937 * editfns.c (Fformat): Correctly handle text properties on "%%".
13939 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13941 * xterm.c (x_draw_composite_glyph_string_foreground):
13942 * w32term.c (x_draw_composite_glyph_string_foreground):
13943 * term.c (encode_terminal_code):
13944 * composite.c (composition_update_it, get_composition_id):
13945 * xdisp.c (get_next_display_element)
13946 (fill_composite_glyph_string): Add comments about special meaning
13947 of TAB characters in a composition.
13949 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13951 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13952 This occurs when processing a multibyte format.
13953 Problem reported by Wolfgang Jenker.
13955 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13957 * xdisp.c (try_cursor_movement): Only check for exact match if
13958 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13960 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13962 Remove unused external symbols.
13963 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13964 * xdisp.c (calc_pixel_width_or_height): Now static.
13965 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13966 * indent.c (check_display_width):
13967 * w32term.c: Fix comment to match code.
13968 * xterm.c, xterm.h (x_catching_errors): Remove.
13970 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13972 * xselect.c: Use signed conversions more consistently (Bug#9498).
13973 (selection_data_to_lisp_data): Assume incoming selection data are
13974 signed integers, not unsigned. This is to be consistent with
13975 outgoing selection data, which was modified to use signed integers
13976 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13977 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13978 expects long, not unsigned long.
13980 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13982 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13983 computation of loop end. Reported by Johan Bockgård
13986 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13988 * frame.c (Fother_visible_frames_p): Function deleted.
13990 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13992 * indent.c (compute_motion): Process display vector front to back
13993 rather than the other way around. (Bug#2496)
13995 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13997 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13999 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
14001 * minibuf.c (Fread_from_minibuffer): Doc fix.
14003 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14005 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
14006 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
14008 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
14010 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
14011 value for non-existent files.
14013 2011-09-11 Eli Zaretskii <eliz@gnu.org>
14015 * fileio.c (Finsert_file_contents): If the file cannot be opened,
14016 set its "size" to -1. This will set the modtime_size field of
14017 the corresponding buffer to -1, which is what
14018 verify-visited-file-modtime expects for files that do not exist.
14021 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
14023 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
14025 * lisp.h: ... from here. push_key_description is no longer
14026 defined in keyboard.c, so its declaration should not be in
14027 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14028 logically belongs with push_key_description.
14030 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14032 * buffer.h: Include <sys/types.h> instead of <time.h>.
14033 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14034 Problem reported by Herbert J. Skuhra.
14036 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14038 * xml.c (parse_region): Make the parsing work for
14039 non-comment-starting XML files again (bug#9144).
14041 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14043 * image.c (gif_load): Fix calculation of bottom and right corner.
14046 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14048 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14049 redisplay in small windows.
14051 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14053 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14055 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14057 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14058 Operate on live windows only.
14060 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14062 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14064 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14066 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14067 only under bidi iteration.
14069 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14071 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14073 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14075 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14076 Without this fix, the command to link temacs failed due to an
14077 undefined symbol __builtin_isnan. This is because
14078 /usr/include/iso/math_c99.h #defines isnan(x) to
14079 __builtin_isnan(x), but the bundled gcc, which identifies itself
14080 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14082 * floatfns.c (isnan): #undef, and then #define to a clone of
14084 (Fisnan): Always define, since it's always available now.
14085 (syms_of_floatfns): Always define isnan at the Lisp level.
14087 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14089 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14091 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14093 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14094 The previous code assumed that file offsets (off_t values) fit in
14095 EMACS_INT variables, which is not true on typical 32-bit hosts.
14096 The code messed up by falsely reporting buffer overflow in cases
14097 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14098 when "big" contains more than 2**29 bytes, even though this
14099 inserts just one byte and does not overflow the buffer.
14100 (Finsert_file_contents): Store file offsets as off_t
14101 values, not as EMACS_INT values. Check for overflow when
14102 converting between EMACS_INT and off_t. When checking for
14103 buffer overflow or for overlap, take the offsets into account.
14104 Don't use EMACS_INT for small values where int suffices.
14105 When checking for overlap, fix a typo: ZV was used where
14106 ZV_BYTE was intended.
14107 (Fwrite_region): Don't assume off_t fits into 'long'.
14108 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14110 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14112 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14114 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14116 sprintf-related integer and memory overflow issues (Bug#9412).
14118 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14119 (esprintf, exprintf, evxprintf): New functions.
14120 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14121 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14122 (modify_event_symbol): Do not assume that the length of
14123 name_alist_or_stem is safe to alloca and fits in int.
14124 (Fexecute_extended_command): Likewise for function name and binding.
14125 (Frecursion_depth): Wrap around reliably on integer overflow.
14126 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14127 since some callers pass EMACS_INT values.
14128 (Fsingle_key_description): Don't crash if symbol name contains more
14129 than MAX_ALLOCA bytes.
14130 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14131 (get_minibuffer): Arg is now EMACS_INT, not int.
14132 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14133 (esprintf, exprintf, evxprintf): New decls.
14134 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14136 * dbusbind.c (signature_cat): New function.
14137 (xd_signature, Fdbus_register_signal):
14138 Do not overrun buffer; instead, report string overflow.
14140 * dispnew.c (add_window_display_history): Don't overrun buffer.
14141 Truncate instead; this is OK since it's just a log.
14143 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14144 even if the time zone offset is outlandishly large.
14145 Don't mishandle offset == INT_MIN.
14147 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14148 when creating daemon; the previous buffer-overflow check was incorrect.
14150 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14151 which has the guts of the old verror function.
14153 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14154 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14156 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14157 (font_unparse_xlfd): Don't blindly alloca long strings.
14158 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14159 fits in int, when using sprintf. Use single snprintf to count
14160 length of string rather than counting it via multiple sprintfs;
14161 that's simpler and more reliable.
14162 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14163 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14164 sprintf, in case result does not fit in int.
14166 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14167 (fontset_from_font): Print it.
14169 * frame.c (tty_frame_count): Now printmax_t, not int.
14170 (make_terminal_frame, set_term_frame_name): Print it.
14171 (x_report_frame_params): In X, window IDs are unsigned long,
14172 not signed long, so print them as unsigned.
14173 (validate_x_resource_name): Check for implausibly long names,
14174 and don't assume name length fits in 'int'.
14175 (x_get_resource_string): Don't blindly alloca invocation name;
14176 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14179 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14180 (xg_check_special_colors, xg_set_geometry):
14181 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14183 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14184 Use esprintf, not sprintf, in case result does not fit in int.
14186 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14187 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14188 it as a large positive number.
14189 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14190 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14192 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14193 in case result does not fit in int.
14195 * print.c (float_to_string): Detect width overflow more reliably.
14196 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14197 buffer overrun. Don't assume list length fits in 'int'. Treat
14198 print length of 0 as 0, not as infinity; to be consistent with other
14199 uses of print length in this function. Don't overflow print length
14200 index. Don't assume hash table size fits in 'long', or that
14201 vectorlike size fits in 'unsigned long'.
14203 * process.c (make_process): Use printmax_t, not int, to format
14204 process-name gensyms.
14206 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14208 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14209 to avoid potential buffer overrun.
14211 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14212 if X resource line is longer than 512 bytes.
14214 * xfns.c (x_window): Make sprintf buffer a bit bigger
14215 to avoid potential buffer overrun.
14217 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14219 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14221 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14223 Integer overflow fixes for scrolling, etc.
14224 Without these, Emacs silently mishandles large integers sometimes.
14225 For example, "C-u 4294967297 M-x recenter" was treated as if
14226 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14228 * xdisp.c (try_window_id): Check Emacs fixnum range before
14229 converting to 'int'.
14231 * window.c (window_scroll_line_based, Frecenter):
14232 Check that an Emacs fixnum is in range before assigning it to 'int'.
14233 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14234 values converted from Emacs fixnums.
14235 (Frecenter): Don't wrap around a line count if it is out of 'int'
14236 range; instead, treat it as an extreme value.
14237 (Fset_window_configuration, compare_window_configurations):
14238 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14240 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14241 that can exceed INT_MAX. Check that EMACS_INT value is in range
14242 before assigning it to the (possibly-narrower) index.
14243 (match_limit): Don't assume that a fixnum can fit in 'int'.
14245 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14248 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14249 (Fvertical_motion): Don't wrap around LINES values that don't fit
14250 in 'int'. Instead, treat them as extreme values. This is good
14251 enough for windows, which can't have more than INT_MAX lines anyway.
14253 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14255 * Require libxml/parser.h to avoid compilation warning.
14257 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14259 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14260 since this reportedly can destroy thread storage.
14262 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14264 * syntax.c (find_defun_start): Update all cache variables if
14265 exiting early (Bug#9401).
14267 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14269 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14271 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14272 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14273 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14275 * term.c (tty_append_glyph): New function.
14276 (produce_stretch_glyph): Static function and its prototype deleted.
14278 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14281 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14283 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14284 when checking :margin (Bug#9390).
14285 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14286 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14287 so that the name doesn't mislead. All uses changed.
14289 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14291 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14294 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14296 * xdisp.c (move_it_to): Don't bail out early when reaching
14297 position beyond to_charpos, if we are scanning backwards.

14299 the first character in the line after the newline.
14301 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14303 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14304 (ccl_driver): Do not generate an out-of-range pointer.
14305 (Fccl_execute_on_string): Remove unnecessary check for
14306 integer overflow, noted by Stefan Monnier in
14307 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14308 Remove a FIXME that didn't need fixing.
14309 Simplify the newly-introduced buffer reallocation code.
14311 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14313 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14315 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14317 Integer and memory overflow issues (Bug#9196).
14319 * doc.c (get_doc_string): Rework so that
14320 get_doc_string_buffer_size is the actual buffer size, rather than
14321 being 1 less than the actual buffer size; this makes xpalloc more
14324 * image.c (x_allocate_bitmap_record, cache_image):
14325 * xselect.c (Fx_register_dnd_atom):
14326 Simplify previous changes by using xpalloc.
14328 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14329 since either will do and ptrdiff_t is convenient with xpalloc.
14331 * charset.c (charset_table_size)
14332 (struct charset_sort_data.priority): Now ptrdiff_t.
14333 (charset_compare): Don't overflow if priorities differ greatly.
14334 (Fsort_charsets): Don't assume list length fits in int.
14335 Check for size-calculation overflow when allocating sort data.
14336 (syms_of_charset): Allocate an initial charset table that is
14337 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14339 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14341 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14342 The actual value is always <= INT_MAX, and leaving it unsigned made
14343 overflow checking harder.
14345 * dispextern.h (struct glyph_matrix.rows_allocated)
14346 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14347 with xpalloc. The values are still always <= INT_MAX.
14349 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14351 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14352 (SAFE_NALLOCA): New macro.
14354 * region-cache.c (struct boundary.pos, find_cache_boundary)
14355 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14356 (set_cache_region, invalidate_region_cache)
14357 (revalidate_region_cache, know_region_cache, region_cache_forward)
14358 (region_cache_backward, pp_cache):
14359 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14360 so that ptrdiff_t * can be passed to xpalloc.
14361 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14362 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14363 (pp_cache): Don't assume cache_len fits in int.
14364 * region-cache.h: Adjust extern decls to match.
14366 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14367 EMACS_INT, since either will do, for xpalloc.
14369 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14370 (xnmalloc, xnrealloc, xpalloc): New functions.
14372 * bidi.c (bidi_shelve_header_size): New constant.
14373 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14374 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14376 * bidi.c (bidi_cache_shrink):
14377 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14379 Don't update size of array until after memory allocation succeeds,
14380 because xmalloc/xrealloc may not return.
14381 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14382 now that we have proper integer overflow checking.
14383 (record_overlay_string, overlay_strings): Catch overflows when
14384 calculating size of overlay_str_buf.
14386 * callproc.c (Fcall_process): Check for size overflow when
14387 calculating size of args2.
14388 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14389 Normally we prefer signed values, but sticking with ptrdiff_t would
14390 require adding more-complicated checks.
14392 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14393 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14394 Redo buffer-overflow calculations to avoid integer overflow.
14395 Add a FIXME comment where memory seems to be over-allocated.
14397 * character.c (Fstring): Check for size-calculation overflow.
14399 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14400 unnecessary integer overflow. Check for size overflow.
14401 (encode_coding_object): Don't update size until xmalloc succeeds.
14403 * composite.c (get_composition_id): Check for overflow in glyph
14404 length calculations.
14406 Integer and memory overflow fixes for display code.
14407 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14408 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14409 (scrolling_window): Check for overflow in size calculations.

14421 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
14422 (get_doc_string): Check for size calculation overflow.
14423 Don't update size until allocation succeeds.
14424 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
14425 EMACS_INT, where ptrdiff_t will do.
14426 (Fsubstitute_command_keys): Check for string overflow.
14428 * editfns.c (set_time_zone_rule): Don't assume environment length
14430 (message_length): Now ptrdiff_t, not int.
14431 (Fmessage_box): Don't update size until allocation succeeds.
14432 Don't assume message length fits in int.
14433 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14435 * emacs.c (main): Do not reallocate argv, since there is a null at
14436 the end that can be overwritten, and this way there's no need to
14437 worry about size-calculation overflow.
14438 (sort_args): Check for size-calculation overflow.
14440 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14442 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
14444 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
14445 (x_set_scroll_bar_width, x_figure_window_size):
14446 Check for integer overflow.
14447 (x_set_alpha): Do not assume XINT fits in int.
14449 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14450 This is for the members text_lines, text_cols, total_lines, total_cols,
14451 where the system imposes an 'int' limit.
14453 * fringe.c (Fdefine_fringe_bitmap):
14454 Don't update size until alloc works.
14456 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
14457 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
14459 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14460 Check for size-calculation overflow.
14461 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14462 do, as we prefer signed integers.
14463 (id_to_widget.max_size, id_to_widget.used)
14464 (xg_store_widget_in_map, xg_remove_widget_from_map)
14465 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
14466 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
14467 Use and return ptrdiff_t, not int.
14468 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14469 * gtkutil.h: Change prototypes to match the above.
14471 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14472 are duplicate now that they've been promoted to lisp.h.
14473 (x_allocate_bitmap_record, x_alloc_image_color)
14474 (make_image_cache, cache_image, xpm_load):

14488 calculations. Don't update size until allocation succeeds.
14489 Redo calculations to avoid overflow.

14518 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14519 for command line length. Do not attempt to address one before the
14520 beginning of an array, as that's not portable.
14522 * term.c (max_frame_lines): Remove; unused.
14523 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
14525 (encode_terminal_code, calculate_costs): Check for size
14526 calculation overflow.

14532 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
14533 subtracting pointers.

14548 Use ptrdiff_t, not int, for sizes.
14549 (Finternal_make_lisp_face, cache_face):
14550 Check for size calculation overflow.
14551 (cache_face): Treat size calculation overflows as if they were
14552 memory exhaustion (the usual treatment), rather than aborting.
14554 * xfns.c (x_encode_text, x_set_name_internal)
14555 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14556 sizes, since they can exceed INT_MAX in size. Check for size

14560 (xg_select): Check for size calculation overflow.
14561 Don't update size until alloc done.
14563 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14564 as sprintf is limited to int lengths.
14566 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14567 (X_LONG_MIN): New macros.
14568 Use them to make the following changes clearer.
14569 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14570 This change doesn't affect the value now, but it may help remind
14571 future maintainers not to raise the value too much later.
14572 (SELECTION_QUANTUM): Remove, replacing with ...
14573 (selection_quantum): ... new function, which avoids overflow.
14575 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14576 assumption that selection length fits in 'int'.

14589 (lisp_data_to_selection_data, x_property_data_to_lisp):

14593 Don't store size until memory allocation succeeds.
14594 (x_get_window_property): Plug memory leak on memory exhaustion.
14595 Don't double-block input; malloc is safe here. Don't assume 2**34
14596 - 4 fits in unsigned long. Add an xassert to check
14597 XGetWindowProperty overflow. Be more careful about overflow
14598 calculations, and distinguish size from memory overflow better.
14599 (receive_incremental_selection): When tracing, don't assume
14600 unsigned int is less than INT_MAX.
14601 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14602 harmful) conversions of unsigned short to int.
14603 (lisp_data_to_selection_data): Don't assume that integers
14604 in the range -65535 through -1 fit in an X unsigned short.
14605 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14606 result parameters unless successful. Rely on cons_to_unsigned
14607 to report problems with elements; the old code wasn't right anyway.
14608 (x_check_property_data): Check for int overflow; we cannot use
14609 a wider type due to X limits.
14610 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

14642 * lisp.h (hash_lookup, hash_put):
14643 * minibuf.c (Ftest_completion):
14644 Use ptrdiff_t for hash table indexes, not int (which is too
14645 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14646 32-bit --with-wide-int hosts).
14648 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14649 Add a FIXME comment about memory leaks.
14650 (syms_of_charset): Don't assume xmalloc returns.
14652 Don't assume that stated character widths fit in int.

14654 * character.h (CHAR_WIDTH):
14655 * indent.c (MULTIBYTE_BYTES_WIDTH):
14656 Use sanitize_char_width to avoid undefined and/or bad behavior
14657 with outlandish widths.
14658 * character.h (sanitize_tab_width): Rename from sanitize_width,
14659 now that we have two such functions. All uses changed.
14660 (sanitize_char_width): New inline function.
14662 Don't assume that tab-width fits in int.
14663 * character.h (sanitize_width): New inline function.

14680 exceed limits imposed by XClientMessageEvent, as well as the usual
14681 ptrdiff_t and size_t limits.
14683 * keyboard.c: Overflow, signedness and related fixes.
14684 (make_lispy_movement): Use same integer type in forward decl
14685 that is used in the definition.
14686 (read_key_sequence, keyremap_step):
14687 Change bufsize argument back to int, undoing my 2011-03-30 change.
14688 We prefer signed types, and int is wide enough here.
14689 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14690 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14691 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14692 length, not size_t. Use ptrdiff_t for index, not int.
14693 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14694 possibility of integer overflow.
14696 Overflow, signedness and related fixes for images.

14706 * xdisp.c (calc_pixel_width_or_height):
14707 * xfns.c (image_cache_refcount):
14708 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

14718 (lookup_image): Remove unnecessary tests.
14719 (xbm_image_p): Locals are now of int, not EMACS_INT,
14720 since parse_image_check makes sure they fit into int.
14721 (png_load, gif_load, svg_load_image):
14722 Prefer int to unsigned where either will do.
14723 (tiff_handler): New function, combining the cores of the
14724 old tiff_error_handler and tiff_warning_handler.
14725 This function is rewritten to use vsnprintf and thereby avoid
14726 stack buffer overflows. It uses only the features of vsnprintf
14727 that are common to both POSIX and native Microsoft.
14728 (tiff_error_handler, tiff_warning_handler): Use it.
14729 (tiff_load, gif_load, imagemagick_load_image):
14730 Don't assume :index value fits in 'int'.
14731 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14732 (imagemagick_load_image): Check that crop parameters fit into
14733 the integer types that MagickCropImage accepts. Don't assume
14734 Vimagemagick_render_type has a nonnegative value. Don't assume
14735 size_t fits in 'long'.
14736 (gs_load): Use printmax_t to print the widest integers possible.
14737 Check for integer overflow when computing image height and width.

14750 (handle_single_display_spec): If the display spec is of the form
14751 `(space ...)', and specifies display in the text area, return 2
14753 (try_cursor_movement): Check for the need to scroll more
14754 accurately, and prefer exact match for point under bidi.
14755 Don't advance `row' beyond the last row of the window.

14776 positioning on the newline at EOL of R2L text within L2R
14777 paragraph, and vice versa.
14778 (try_cursor_movement): Check continued rows, in addition to
14779 continuation rows. Fixes unwarranted scroll when point enters a
14780 continued line of R2L text within an L2R paragraph, or vice versa.
14781 (cursor_row_p): Consider the case of point being equal to
14782 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14783 from the end of a short line to the beginning of a continued line
14784 of R2L text within L2R paragraph.

14808 * xdisp.c (redisplay_window): When computing centering_position,
14809 account for the height of the header line. (Bug#8874)
14811 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14812 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14813 candidate is selected by the mouse, and that candidate has a
14814 composed character under the mouse.
14816 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14817 coordinates reported by pos-visible-in-window-p for a composed
14818 character in column zero.

14827 consider it a hit if to_charpos is anywhere in the range of the
14828 composed buffer positions.
14830 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14832 * image.c (gif_load): Don't assume that each subimage has the same
14833 dimensions as the base image. Handle disposal method that is
14834 "undefined" by the gif spec (Bug#9335).
14836 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14838 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14844 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14845 from an Org mode buffer to a Speedbar frame.
14847 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14848 a composition, take its buffer position from IT->cmp_it.charpos.
14849 Fixes cursor positioning at the beginning of a line that begins
14850 with a composed character.
14852 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14854 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14855 character bidirectional type, use STRONG_L instead. Fixes crashes
14856 in a buffer produced by `describe-categories'.
14858 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14859 members before the level stack, so they would be saved and
14860 restored when copying iterator state. Fixes incorrect reordering
14861 around TABs covered by display properties.
14863 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

14997 the iterator structure wrt the object coming from a display
14998 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14999 properties. (Bug#9284)

15197 instead of hard-coded value of 2.
15198 (nsfont_draw): Call ns_draw_text_decoration instead.
15200 * nsterm.h: Add declaration for ns_draw_text_decoration.
15202 * nsterm.m (ns_draw_text_decoration): New function for drawing
15203 underline, overline, and strike-through.
15204 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15205 ns_draw_text_decoration. Change treatment of cursor drawing to
15206 accommodate underlining, etc.
15208 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15210 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15213 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15215 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15216 Without this fix, if a signal arrives just after memory fills up,
15217 'malloc' might be invoked reentrantly.
15219 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15220 In other words, assume that every image size is allowed, on non-X
15221 hosts. This assumption is probably wrong, but it lets Emacs compile.
15223 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15225 * regex.c (re_iswctype): Convert return values to boolean.
15227 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15229 * xdisp.c (compute_display_string_pos): Don't use cached display
15230 string position if the buffer had its restriction changed.
15233 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15235 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15237 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15239 Integer signedness and overflow and related fixes. (Bug#9079)
15241 * bidi.c: Integer size and overflow fixes.
15242 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15243 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15244 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15245 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15246 (bidi_find_other_level_edge):
15247 Use ptrdiff_t instead of EMACS_INT where either will do.
15248 This works better on 32-bit hosts configured --with-wide-int.
15249 (bidi_cache_ensure_space): Check for size-calculation overflow.
15250 Use % rather than repeated addition, for better worst-case speed.
15251 Don't set bidi_cache_size until after xrealloc returns, because it
15253 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15254 (bidi_cache_ensure_space): Also check that the bidi cache size
15255 does not exceed that of the largest Lisp string or buffer. See Eli
15256 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15258 * alloc.c (__malloc_size_t): Remove.
15259 All uses replaced by size_t. See Andreas Schwab's note
15260 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15262 * image.c: Improve checking for integer overflow.
15263 (check_image_size): Assume that f is nonnull, since
15264 it is always nonnull in practice. This is one less thing to
15265 worry about when checking for integer overflow later.
15266 (x_check_image_size): New function, which checks for integer
15267 overflow issues inside X.
15268 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15269 This removes the need for a memory_full check.
15270 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15271 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15272 (xbm_read_bitmap_data): Change locals back to 'int', since
15273 their values must fit in 'int'.
15274 (xpm_load_image, png_load, tiff_load):
15275 Invoke x_create_x_image_and_pixmap earlier,
15276 to avoid much needless work if the image is too large.
15277 (tiff_load): Treat overly large images as if
15278 x_create_x_image_and_pixmap failed, not as malloc failures.
15279 (gs_load): Use x_check_image_size.
15281 * gtkutil.c: Omit integer casts.
15282 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15283 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15285 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15287 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15288 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15289 would wrongly return t on a 64-bit host.
15291 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15292 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15293 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15294 and therefore cause GCC to emit a bogus diagnostic in some cases.
15296 * image.c: Integer signedness and overflow and related fixes.
15297 This is not an exhaustive set of fixes, but it's time to
15298 record what I've got.
15299 (lookup_pixel_color, check_image_size): Remove redundant decls.
15300 (check_image_size): Don't assume that arbitrary EMACS_INT values
15301 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15302 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15303 (tiff_load, imagemagick_load_image):
15304 Check for overflow in size calculations.
15305 (x_create_x_image_and_pixmap): Remove unnecessary test for
15306 xmalloc returning NULL; that can't happen.
15307 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15308 (xpm_color_bucket): Use better integer hashing function.
15309 (xpm_cache_color): Don't possibly over-allocate memory.
15310 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15311 (gif_memory_source):
15312 Use ptrdiff_t, not int or size_t, to record sizes.
15313 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15314 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15315 either works, as we prefer signed integers.
15316 (tiff_read_from_memory, tiff_write_from_memory):
15317 Return tsize_t, not size_t, since that's what the TIFF API wants.
15318 (tiff_read_from_memory): Don't fail simply because the read would
15319 go past EOF; instead, return a short read.
15320 (tiff_load): Omit no-longer-needed casts.
15321 (Fimagemagick_types): Don't assume size fits into 'int'.
15323 Improve hashing quality when configured --with-wide-int.
15324 * fns.c (hash_string): New function, taken from sxhash_string.
15325 Do not discard information about ASCII character case; this
15326 discarding is no longer needed.
15327 (sxhash-string): Use it. Change sig to match it. Caller changed.
15328 * lisp.h: Declare it.
15329 * lread.c (hash_string): Remove, since we now use fns.c's version.
15330 The fns.c version returns a wider integer if --with-wide-int is
15331 specified, so this should help the quality of the hashing a bit.
15333 * emacs.c: Integer overflow minor fix.
15334 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15335 Define only if GNU_LINUX.
15336 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15338 * dispnew.c: Integer signedness and overflow fixes.
15339 Remove unnecessary forward decls, that were a maintenance hassle.
15340 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15342 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15343 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15344 (prepare_desired_row, line_draw_cost):
15345 Use int, not unsigned, where either works.
15346 (save_current_matrix, restore_current_matrix):
15347 Use ptrdiff_t, not size_t, where either works.
15348 (init_display): Check for overflow more accurately, and without
15349 relying on undefined behavior.
15351 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15352 Remove, replacing with the new symbols in lisp.h. All uses changed.
15353 * fileio.c (make_temp_name):
15354 * filelock.c (lock_file_1, lock_file):
15355 * xdisp.c (message_dolog):
15356 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15357 Use pMd etc. instead.
15358 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15359 replacing the pWIDE etc. symbols removed from editfns.c.
15361 * keyboard.h (num_input_events): Now uintmax_t.
15362 This is (very slightly) less likely to mess up due to wraparound.
15365 * buffer.c: Integer signedness fixes.
15366 (alloc_buffer_text, enlarge_buffer_text):
15367 Use ptrdiff_t rather than size_t when either will do, as we prefer
15370 * alloc.c: Integer signedness and overflow fixes.
15371 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15372 (__malloc_size_t): Default to size_t, not to int.
15373 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15374 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15375 Prefer ptrdiff_t to size_t when either would do, as we prefer
15377 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15378 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15379 Now const. Initialize with values that are in range even if char
15381 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15382 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15383 These functions do the right thing with sizes > 2**32.
15384 (check_depth): Now ptrdiff_t, not int.
15385 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15386 Adjust to new way of storing sizes. Check for size overflow bugs
15388 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15389 slightly wrong anyway, as it missed one instance of
15390 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15391 (refill_memory_reserve): Omit needless cast to size_t.
15392 (mark_object_loop_halt): Mark as externally visible.
15394 * xselect.c: Integer signedness and overflow fixes.
15395 (Fx_register_dnd_atom, x_handle_dnd_message):
15396 Use ptrdiff_t, not size_t, since we prefer signed.
15397 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15398 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15399 x_dnd_atoms_size and x_dnd_atoms_length.
15401 * doprnt.c: Prefer signed to unsigned when either works.
15403 * doprnt.c (doprnt):
15405 * xdisp.c (vmessage):
15406 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15407 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15408 prefer signed arithmetic to avoid comparison confusion.
15409 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15410 but is a bit tricky.
15412 Assume freestanding C89 headers, string.h, stdlib.h.
15413 * data.c, doprnt.c, floatfns.c, print.c:
15414 Include float.h unconditionally.
15415 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15416 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15417 * regex.c: Likewise for stddef.h, string.h.
15418 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15419 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15420 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15421 (STDC_HEADERS): Remove obsolete defines.
15422 * sysdep.c: Include limits.h unconditionally.
15424 Assume support for memcmp, memcpy, memmove, memset.
15425 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15426 * regex.c (memcmp, memcpy):
15427 Remove; we assume C89 now.
15429 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15430 (__malloc_safe_bcopy): Remove; no longer needed.
15432 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15433 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15434 well either way, and we prefer signed to unsigned.
15436 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15438 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15439 closes the connection while we're reading (bug#9182).
15441 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15443 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15444 are specified (Bug#9168).
15446 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15448 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15449 Found by GCC static checking and --with-wide-int on a 32-bit host.
15451 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15453 * xdisp.c (compute_display_string_pos): Fix logic of caching
15454 previous display string position. Initialize cached_prev_pos to
15455 -1. Fixes slow-down at the beginning of a buffer.
15457 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15459 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15460 for attrs[LFACE_FONTSET_INDEX].
15462 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15464 * xml.c (parse_region): Remove unused local
15465 that was recently introduced.
15467 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15469 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15470 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15472 * xdisp.c (move_it_in_display_line_to): Record the best matching
15473 position for TO_CHARPOS while scanning the line, and restore it on
15474 exit if none of the characters scanned was an exact match.
15475 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15476 when exact match is impossible due to invisible text, and the
15477 lines are truncated.
15479 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15481 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15484 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15486 Fix a significant slow-down of cursor motion with C-n, C-p,
15487 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15488 auto-repeat under bidi redisplay in fontified buffers.
15489 * xdisp.c (compute_stop_pos_backwards): New function.
15490 (next_element_from_buffer): Call compute_stop_pos_backwards to
15491 find a suitable prev_stop when we find ourselves before
15493 (reseat): Don't look for prev_stop, as that could mean a very long
15495 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15496 <cached_disp_overlay_modiff>: Cache for last found display string
15498 (compute_display_string_pos): Return the cached position if asked
15499 about the same buffer in the same area of character positions, and
15500 the buffer wasn't changed since the time the display string
15501 position was cached.
15503 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15505 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15506 is an integer, which is important for empty lines. (Bug#9149)
15508 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15510 * frame.c (Fmodify_frame_parameters): In tty case, update the
15511 default face if necessary (Bug#4238).
15513 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15515 * editfns.c (Fstring_to_char): No need to explain what a character
15516 is in the docstring (Bug#6576).
15518 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15520 * xml.c (parse_region): Make sure we always return a tree.
15522 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15524 * xml.c (parse_region): If a document contains only comments,
15527 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15529 * xml.c (make_dom): Return comments, too.
15531 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15534 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15535 and the surrounding thread.
15536 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15537 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15538 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15540 * s/openbsd.h (BROKEN_SIGIO): Define.
15541 * unexelf.c (unexec) [__OpenBSD__]:
15542 Don't update the .mdebug section of the Alpha COFF symbol table.
15544 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15546 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15549 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15551 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15552 This fixes some race conditions on the permissions of any newly
15555 * alloc.c (valid_pointer_p): Use pipe, not open.
15556 This fixes some permissions issues when debugging.
15558 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15559 If fchown fails to set both uid and gid, try to set just gid,
15560 as that is sometimes allowed. Adjust the file's mode to eliminate
15561 setuid or setgid bits that are inappropriate if fchown fails.
15563 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15565 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15566 to compare Lisp_Objects.
15567 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15568 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15569 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15571 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15573 * lread.c (read_integer): Unread even EOF character.
15574 (read1): Likewise. Properly record start position of symbol.
15576 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15577 symbol character follows.
15579 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15581 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15582 This works around a problem with the previous change to Fcopy_file.
15583 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15584 and without this change, GCC might complain about discarding
15585 fchown's return value.
15587 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15589 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15591 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15593 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15595 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15597 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15598 it's used from the C level.
15600 * process.c: Use the same condition for POLL_FOR_INPUT in both
15601 keyboard.c and process.c (bug#1858).
15603 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15605 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15606 (Fgnutls_boot): Use it.
15608 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15610 * doc.c (Fsubstitute_command_keys): Revert last change.
15612 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15614 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15615 quotes the next character, and doesn't affect other longer
15616 sequences (bug#8935).
15618 * lread.c (syms_of_lread): Clarify that is isn't only
15619 `eval-buffer' and `eval-defun' that's affected by
15620 `lexical-binding' (bug#8460).
15622 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15624 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15625 bidi redisplay when a line includes both an image and is truncated.
15627 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15629 Fix minor problems found by static checking.
15630 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15631 (elsz): Now a signed constant, not a size_t var. We prefer signed
15632 types to unsigned, to avoid integer comparison confusion. Without
15633 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15634 "cannot optimize loop, the loop counter may overflow", a symptom
15636 * indent.c (Fvertical_motion): Mark locals as initialized.

16161 (clone_per_buffer_values): Don't assume that

16163 This isn't true in general, and it's particularly not true
16164 if Emacs is configured with --with-wide-int.
16165 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16166 New macros, used in the buffer.c change.

16202 Random fixes. E.g., (random) never returned negative values.
16203 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16204 subseconds part to the entropy, as that's a bit more random.
16205 Prefer signed to unsigned, since the signedness doesn't matter and
16206 in general we prefer signed. When given a limit, use a
16207 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16208 latter isn't right if USE_2_TAGS_FOR_INTS.
16209 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16210 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16222 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16223 This is more efficient than Ffile_directory_p and avoids a minor race.
16225 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16227 * buffer.c (Foverlay_put): Say what the return value is
16230 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16231 is a directory before asking whether to use the file name
16233 (barf_or_query_if_file_exists): Make the "File is a directory"
16234 error be more correct.
16236 * fns.c (Frequire): Remove the mention of the .gz files, since
16237 that's installation-specific, but keep the mention of
16238 `get-load-suffixes'.

16242 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

16250 Qgnutls_bootprop_verify_error (which is no longer used).
16252 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16253 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16254 Also (re)move comments that are misplaced or no longer relevant.
16256 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16258 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

16283 * lread.c (syms_of_lread): Mention single symbols defined by
16284 `defvar' or `defconst' (bug#7154).
16286 * fns.c (Frequire): Mention .el.gz files (bug#7314).
16287 (Frequire): Mention get-load-suffixes.

16317 (syms_of_keymap): Defsubr make-composed-keymap.
16318 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

16355 * eval.c (struct backtrace): Simplify and port the data structure.
16356 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16357 signed bit field, as this assumption is not portable and it makes
16358 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16359 "char debug_on_exit : 1" as this is not portable either; instead,
16360 use the portable "unsigned int debug_on_exit : 1". Remove unused
16361 member evalargs. Remove obsolete comments about cc bombing out.
16363 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16515 * xfaces.c (syms_of_xfaces):
16516 * xfns.c (syms_of_xfns):
16517 * xmenu.c (syms_of_xmenu):
16518 * xsettings.c (syms_of_xsettings):
16519 * xterm.c (syms_of_xterm): Use DEFSYM.
16521 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
16523 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
16525 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
16527 Integer and buffer overflow fixes (Bug#8873).
16529 * print.c (printchar, strout): Check for string overflow.
16530 (PRINTPREPARE, printchar, strout):
16531 Don't set size unless allocation succeeds.
16533 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16534 for sizes. Check for string overflow more accurately.
16535 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
16537 * macros.c: Integer and buffer overflow fixes.
16538 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16539 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
16540 Use ptrdiff_t, not int, for sizes.
16541 Don't increment bufsize until after realloc succeeds.
16542 Check for size-calculation overflow.
16543 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16545 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16547 * lread.c: Integer overflow fixes.
16548 (read_integer): Radix is now EMACS_INT, not int,
16549 to improve quality of diagnostics for out-of-range radices.
16550 Calculate buffer size correctly for out-of-range radices.
16551 (read1): Check for integer overflow in radices, and in
16552 read-circle numbers.
16553 (read_escape): Avoid int overflow.
16554 (Fload, openp, read_buffer_size, read1)
16555 (substitute_object_recurse, read_vector, read_list, map_obarray):
16556 Use ptrdiff_t, not int, for sizes.
16557 (read1): Use EMACS_INT, not int, for sizes.
16558 Check for size overflow.
16560 * image.c (cache_image): Check for size arithmetic overflow.

16564 (prev_saved_doc_string_size, prev_saved_doc_string_length):
16565 Now ptrdiff_t, not int.

16569 (read_escape): Check for hex character overflow.
16571 2011-06-22 Leo Liu <sdl.web@gmail.com>
16573 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16574 Move to minibuffer.el.
16576 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16578 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16579 The following patches are for when GLYPH_DEBUG && !XASSERT.
16580 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16581 * dispnew.c (flush_stdout):
16582 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16583 Mark as externally visible.
16584 * dispnew.c (check_window_matrix_pointers): Now static.
16585 * dispnew.c (window_to_frame_vpos):
16586 * xfns.c (unwind_create_frame):
16587 * xterm.c (x_check_font): Remove unused local.
16588 * scroll.c (CHECK_BOUNDS):
16589 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16590 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16591 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16592 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16593 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16595 (debug_method_add): Use va_list and vsprintf rather than relying
16596 on undefined behavior with wrong number of arguments.
16597 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16598 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16599 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16600 since we're not interested in debugging glyphs with old libraries.
16601 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16602 GCC 4.6.0's static checking.
16604 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16606 Integer overflow and signedness fixes (Bug#8873).

16615 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
16616 (x_create_bitmap_from_xpm_data):
16617 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16618 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16620 * xfaces.c (load_pixmap):
16621 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16622 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16623 (.bitmaps_last, struct x_output.icon_bitmap):
16624 Use ptrdiff_t, not int, for bitmap indexes.
16625 (x_allocate_bitmap_record): Check for size overflow.
16626 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16628 Use ptrdiff_t, not int, for overlay counts.
16629 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16630 * editfns.c (overlays_around, get_pos_property):
16631 * textprop.c (get_char_property_and_overlay):
16632 * xdisp.c (next_overlay_change, note_mouse_highlight):
16633 * xfaces.c (face_at_buffer_position):
16634 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16635 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16636 (Fnext_overlay_change, Fprevious_overlay_change)
16637 (mouse_face_overlay_overlaps, Foverlays_in):
16638 Use ptrdiff_t, not int, for sizes.
16639 (overlays_at, overlays_in): Check for size-calculation overflow.
16641 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16643 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16644 (x_session_initialize): Do not assume string length fits in int.
16646 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16647 This is unlikely, but can occur if DPI is outlandish.
16649 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16650 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16652 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16653 * xrdb.c (magic_file_p, search_magic_path):
16654 Omit last arg SUFFIX; it was always 0. All callers changed.
16655 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16657 * xfont.c (xfont_match): Avoid need for strlen.
16659 * xfns.c: Don't assume strlen fits in int.
16660 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16662 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16663 not unsigned long, as we prefer signed integers. All callers changed.
16664 Detect integer overflow in repeat count.
16665 (message_dolog): Don't assume print length fits in 39 bytes.
16666 (display_mode_element): Don't assume strlen fits in int.
16668 * termcap.c: Don't assume sizes fit in int and never overflow.
16669 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16670 (gobble_line): Check for size-calculation overflow.
16672 * minibuf.c (Fread_buffer):
16673 * lread.c (intern, intern_c_string):
16674 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16675 Don't assume string length fits in int.
16677 * keyboard.c (parse_tool_bar_item):
16678 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16680 * font.c: Don't assume string length fits in int.
16681 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16682 Use ptrdiff_t, not int.
16683 (font_intern_prop): Don't assume string length fits in int.
16684 Don't assume integer property fits in fixnum.
16685 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16687 * filelock.c: Fix some buffer overrun and integer overflow issues.
16688 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16689 Reformulate so as not to need the command string.
16690 Invoke gzip -cd rather than gunzip, as it's more portable.
16691 (lock_info_type, lock_file_1, lock_file):
16692 Don't assume pid_t and time_t fit in unsigned long.
16693 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16694 (current_lock_owner): Prefer signed type for sizes.
16695 Use memcpy, not strncpy, where memcpy is what is really wanted.
16696 Don't assume (via atoi) that time_t and pid_t fit in int.
16697 Check for time_t and/or pid_t out of range, e.g., via a network share.
16698 Don't alloca where an auto var works fine.
16700 * fileio.c: Fix some integer overflow issues.
16701 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16702 Don't assume string length fits in int.
16703 (directory_file_name): Don't assume string length fits in long.
16704 (make_temp_name): Don't assume pid fits in int, or that its print
16705 length is less than 20.
16707 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16709 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16711 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16713 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16714 We prefer signed integers, even for size calculations.
16716 * emacs.c: Don't assume string length fits in 'int'.
16717 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16718 (main): Don't invoke strlen when not needed.
16720 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16721 (XD_DEBUG_MESSAGE): Don't waste a byte.
16723 * callproc.c (getenv_internal_1, getenv_internal)
16724 (Fgetenv_internal):
16725 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16727 * lread.c (invalid_syntax): Omit length argument.
16728 All uses changed. This doesn't fix a bug, but it simplifies the
16729 code away from its former Hollerith-constant appearance, and it's
16730 one less 'int' to worry about when looking at integer-overflow issues.
16731 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16733 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16734 This didn't break anything, but it didn't help either.
16735 It's confusing to put a bogus integer in a place where the actual
16736 value does not matter.
16737 (LIST_END_P): Remove unused macro and its bogus comment.
16738 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16740 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16741 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16743 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16744 We prefer signed types, and the value cannot exceed the EMACS_INT
16745 range anyway (because otherwise the length would not be representable).
16746 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16747 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16748 This avoids a GCC warning when WIDE_EMACS_INT.
16750 * indent.c (sane_tab_width): New function.
16751 (current_column, scan_for_column, Findent_to, position_indentation)
16752 (compute_motion): Use it. This is just for clarity.
16753 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16755 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16757 * lisp.h (lint_assume): New macro.
16758 * composite.c (composition_gstring_put_cache):
16759 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16761 * editfns.c, insdel.c:
16762 Omit unnecessary forward decls, to simplify future changes.
16764 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16766 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16768 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16769 Use much-faster test for byte-length change.
16770 Don't assume string byte-length fits in 'int'.
16771 Check that character arg fits in 'int'.
16772 (mapcar1): Declare byte as byte, for clarity.
16774 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16776 * fns.c (concat): Catch string overflow earlier.
16777 Do not rely on integer wraparound.
16779 * dispextern.h (struct it.overlay_strings_charpos)
16780 (struct it.selective): Now EMACS_INT, not int.
16781 * xdisp.c (forward_to_next_line_start)
16782 (back_to_previous_visible_line_start)
16783 (reseat_at_next_visible_line_start, next_element_from_buffer):
16784 Don't arbitrarily truncate the value of 'selective' to int.
16786 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16788 * composite.c: Don't truncate sizes to 'int'.
16789 (composition_gstring_p, composition_reseat_it)
16790 (composition_adjust_point): Use EMACS_INT, not int.
16791 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16792 not EMACS_UINT, for indexes.
16794 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16796 * buffer.c: Include <verify.h>.
16797 (struct sortvec.priority, struct sortstr.priority):
16798 Now EMACS_INT, not int.
16799 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16800 (struct sortstr.size, record_overlay_string)
16801 (struct sortstrlist.size, struct sortlist.used):
16802 Don't truncate size to int.
16803 (record_overlay_string): Check for size-calculation overflow.
16804 (init_buffer_once): Check at compile-time, not run-time.
16806 2011-06-22 Jim Meyering <meyering@redhat.com>
16808 Don't leak an XBM-image-sized buffer
16809 * image.c (xbm_load): Free the image buffer after using it.
16811 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16814 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16815 that Sun C diagnosed.
16816 * fns.c (secure_hash): Fix pointer signedness issue.
16817 * intervals.c (static_offset_intervals): New function.
16818 (offset_intervals): Use it.
16820 2011-06-21 Leo Liu <sdl.web@gmail.com>
16823 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16826 * fns.c (secure_hash): Rename from crypto_hash_function and change
16827 the first arg to accept symbols.
16828 (Fsecure_hash): New primitive.
16829 (syms_of_fns): New symbols.
16831 2011-06-20 Deniz Dogan <deniz@dogan.se>
16833 * process.c (Fset_process_buffer): Clarify return value in
16836 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16838 * dispnew.c (add_window_display_history): Use BVAR.
16840 * xdisp.c (debug_method_add): Use BVAR.
16841 (check_window_end, dump_glyph_matrix, dump_glyph)
16842 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16844 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16847 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16848 check till after the cache is created in init_frame_faces.
16850 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16852 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16854 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16856 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16857 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16858 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16860 Improve buffer-overflow checking (Bug#8873).
16861 * fileio.c (Finsert_file_contents):
16862 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16863 Remove the old (too-loose) buffer overflow checks.
16864 They weren't needed, since make_gap checks for buffer overflow.
16865 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16866 The old code merely checked for Emacs fixnum overflow, and relied
16867 on undefined (wraparound) behavior. The new code avoids undefined
16868 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16870 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16871 Tune. Don't use wider integers than needed. Don't use alloca.
16872 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16874 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16876 * insdel.c, lisp.h (buffer_overflow): New function.
16877 (insert_from_buffer_1, replace_range, replace_range_2):
16878 * insdel.c (make_gap_larger):
16879 * editfns.c (Finsert_char):
16880 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16882 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16884 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16886 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16888 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16889 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16891 * fileio.c: Don't assume EMACS_INT fits in off_t.
16892 (emacs_lseek): New static function.
16893 (Finsert_file_contents, Fwrite_region): Use it.
16894 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16896 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16898 * fns.c: Don't overflow int when computing a list length.
16899 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16900 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16901 truncation on 64-bit hosts. Check for QUIT every
16902 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16903 faster and is responsive enough.
16904 (Flength): Report an error instead of overflowing an integer.
16905 (Fsafe_length): Return a float if the value is not representable
16906 as a fixnum. This shouldn't happen except in contrived situations.
16907 (Fnthcdr, Fsort): Don't assume list length fits in int.
16908 (Fcopy_sequence): Don't assume vector length fits in int.
16910 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16911 (header_size, word_size): New constants.
16912 (allocate_vectorlike): Don't check size overflow here.
16913 (allocate_vector): Check it here instead, since this is the only
16914 caller of allocate_vectorlike that could cause overflow.
16915 Check that the new vector's length is representable as a fixnum.
16917 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16918 The previous code was bogus. For example, next_almost_prime (32)
16919 returned 39, which is undesirable as it is a multiple of 3; and
16920 next_almost_prime (24) returned 25, which is a multiple of 5 so
16921 why was the code bothering to check for multiples of 7?
16923 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16925 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16927 Variadic C functions now count arguments with ptrdiff_t.
16928 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16929 Back then I didn't know that the Emacs coding style prefers signed int.
16930 Also, in the meantime I found a few more instances where arguments
16931 were being counted with int, which may truncate counts on 64-bit
16932 machines, or EMACS_INT, which may be unnecessarily wide.
16933 * lisp.h (struct Lisp_Subr.function.aMANY)
16934 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16935 Arg counts are now ptrdiff_t, not size_t.
16936 All variadic functions and their callers changed accordingly.
16937 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16938 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16939 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16940 * callint.c (Fcall_interactively): Check arg count for overflow,
16941 to avoid potential buffer overrun. Use signed char, not 'int',
16942 for 'varies' array, so that we needn't bother to check its size
16943 calculation for overflow.
16944 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16945 * eval.c (apply_lambda):
16946 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16947 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16948 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16950 * callint.c (Fcall_interactively): Don't use index var as event count.
16952 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16953 * mem-limits.h (SIZE): Remove; no longer used.
16955 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16957 Remove unnecessary casts.
16958 * xterm.c (x_term_init):
16959 * xfns.c (x_set_border_pixel):
16960 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16961 These aren't needed now that we assume ANSI C.
16963 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16964 It's more likely to cause problems (due to unsigned overflow)
16967 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16969 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16971 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16973 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16975 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16977 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16979 GLYPH_CODE_FACE returns EMACS_INT, not int.
16980 * dispextern.h (merge_faces):
16981 * xfaces.c (merge_faces):
16982 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16983 Don't assume EMACS_INT fits in int.
16985 * character.h (CHAR_VALID_P): Remove unused parameter.
16986 * fontset.c, lisp.h, xdisp.c: All uses changed.
16988 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16990 * fns.c (concat): Minor tuning based on overflow analysis.
16991 This doesn't fix any bugs. Use int to hold character, instead
16992 of constantly refetching from Emacs object. Use XFASTINT, not
16993 XINT, for value known to be a character. Don't bother comparing
16994 a single byte to 0400, as it's always less.
16996 * floatfns.c (Fexpt):
16997 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16999 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
17002 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
17004 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
17005 Without this fix, on a 64-bit host (aset S 0 4294967386) would
17006 incorrectly succeed when S was a string, because 4294967386 was
17007 truncated before it was used.
17009 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
17010 Otherwise, an out-of-range integer could cause undefined behavior
17013 * composite.c: Use int, not EMACS_INT, for characters.
17014 (fill_gstring_body, composition_compute_stop_pos): Use int, not
17015 EMACS_INT, for values that are known to be in character range.
17016 This doesn't fix any bugs but is the usual style inside Emacs and
17017 may generate better code on 32-bit machines.
17019 Make sure a 64-bit char is never passed to ENCODE_CHAR.
17020 This is for reasons similar to the recent CHAR_STRING fix.
17021 * charset.c (Fencode_char): Check that character arg is actually
17022 a character. Pass an int to ENCODE_CHAR.
17023 * charset.h (ENCODE_CHAR): Verify that the character argument is no
17024 wider than 'int', as a compile-time check to prevent future regressions
17027 * character.c (char_string): Remove unnecessary casts.
17029 Make sure a 64-bit char is never passed to CHAR_STRING.
17030 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17031 by silently ignoring the top 32 bits, allowing some values
17032 that were far too large to be valid characters.
17033 * character.h: Include <verify.h>.
17034 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17035 arguments are no wider than unsigned, as a compile-time check
17036 to prevent future regressions in this area.
17038 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17039 (Fsubst_char_in_region):
17041 * xdisp.c (decode_mode_spec_coding):
17042 Adjust to CHAR_STRING's new requirement.
17043 * editfns.c (Finsert_char, Fsubst_char_in_region):
17044 * fns.c (concat): Check that character args are actually
17045 characters. Without this test, these functions did the wrong
17046 thing with wildly out-of-range values on 64-bit hosts.
17048 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17049 These casts should not be needed on 32-bit hosts, either.
17050 * keyboard.c (read_char):
17051 * lread.c (Fload): Remove casts to unsigned.
17053 * lisp.h (UNSIGNED_CMP): New macro.
17054 This fixes comparison bugs on 64-bit hosts.
17055 (ASCII_CHAR_P): Use it.
17056 * casefiddle.c (casify_object):
17057 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17058 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17059 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17060 * dispextern.h (FACE_FROM_ID):
17061 * keyboard.c (read_char): Use UNSIGNED_CMP.
17063 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17064 not to EMACS_INT, to avoid GCC warning.
17066 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17068 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17069 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17070 isn't needed on 32-bit machines.
17072 * buffer.c (Fgenerate_new_buffer_name):
17073 Use EMACS_INT for count, not int.
17074 (advance_to_char_boundary): Return EMACS_INT, not int.
17076 * data.c (Qcompiled_function): Now static.
17078 * window.c (window_body_lines): Now static.
17080 * image.c (gif_load): Rename local to avoid shadowing.
17082 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17083 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17084 * alloc.c (make_save_value): Integer argument is now of type
17085 ptrdiff_t, not int.
17086 (mark_object): Use ptrdiff_t, not int.
17087 * lisp.h (pD): New macro.
17088 * print.c (print_object): Use it.
17090 * alloc.c: Use EMACS_INT, not int, to count objects.
17091 (total_conses, total_markers, total_symbols, total_vector_size)
17092 (total_free_conses, total_free_markers, total_free_symbols)
17093 (total_free_floats, total_floats, total_free_intervals)
17094 (total_intervals, total_strings, total_free_strings):
17095 Now EMACS_INT, not int. All uses changed.
17096 (Fgarbage_collect): Compute overall total using a double, so that
17097 integer overflow is less likely to be a problem. Check for overflow
17098 when converting back to an integer.
17099 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17100 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17101 These were 'int' variables that could overflow on 64-bit hosts;
17102 they were never used, so remove them instead of repairing them.
17103 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17104 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17105 Previously, this ceilinged at INT_MAX, but that doesn't work on
17107 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17109 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17110 (allocate_vectorlike): Check for ptrdiff_t overflow.
17111 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17112 when a (possibly-narrower) signed value would do just as well.
17113 We prefer using signed arithmetic, to avoid comparison confusion.
17115 * alloc.c: Catch some string size overflows that we were missing.
17116 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17117 for convenience in STRING_BYTES_MAX.
17118 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17119 The definition here is exact; the one in lisp.h was approximate.
17120 (allocate_string_data): Check for string overflow. This catches
17121 some instances we weren't catching before. Also, it catches
17122 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17123 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17124 and ptrdiff_t and EMACS_INT are both 64 bits.
17126 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17127 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17128 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17130 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17132 * alloc.c (Fmake_string): Check for out-of-range init.
17134 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17136 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17138 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17140 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
17141 xg_get_default_scrollbar_width.
17143 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17144 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17145 (style_changed_cb): Call update_theme_scrollbar_width and call

17151 and height if HAVE_GTK3 (Bug#8505).
17152 (scroll_bar_width_for_theme): New variable.
17153 (update_theme_scrollbar_width): New function.
17154 (xg_get_default_scrollbar_width): Move code to
17155 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
17156 (xg_initialize): Call update_theme_scrollbar_width.
17158 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17160 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17162 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17164 * frame.c (make_frame): Call other_buffer_safely instead of
17167 * window.c (temp_output_buffer_show): Call display_buffer with
17168 second argument Vtemp_buffer_show_specifiers and reset latter
17169 immediately after the call.
17170 (Vtemp_buffer_show_specifiers): New variable.
17171 (auto_window_vscroll_p, next_screen_context_lines)
17172 (Vscroll_preserve_screen_position): Remove leading asterisks from

17217 * window.c (delete_deletable_window): Re-add.
17218 (Fset_window_configuration): Rewrite to handle dead buffers and
17219 consequently deletable windows.
17220 (window_tree, Fwindow_tree): Remove. Supply functionality in
17222 (compare_window_configurations): Simplify code.

17355 Remove static from declaration of Qdelete_window, it's
17356 temporarily needed by Fbury_buffer.
17357 (replace_window): Don't assign orig_top_line and
17359 (Fdelete_window, delete_window): Remove. Window deletion is

17361 (window_loop): Remove DELETE_OTHER_WINDOWS case.
17362 Replace Fdelete_window calls with calls to Qdelete_window.
17363 (Fdelete_other_windows): Remove. Deleting other windows is

17768 * gnutls.c: Use Emacs's memory allocators.
17769 Without this change, the gnutls library would invoke malloc etc.
17770 directly, which causes problems on non-SYNC_INPUT hosts, and which
17771 runs afoul of improving memory_full behavior. (Bug#8761)
17772 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17773 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17774 xfree instead of the default malloc, realloc, free.
17775 (Fgnutls_boot): No need to check for memory allocation failure,
17776 since xmalloc does that for us.

17805 need to be updated by these changes.
17806 * fns.c (make_hash_table, maybe_resize_hash_table):
17807 Check for integer overflow with large hash tables.
17808 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17809 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17810 (SXHASH_REDUCE): New macro.

17814 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17815 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17816 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17817 Rewrite to use FIXNUM_BITS, as this simplifies things.
17818 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17819 Adjust signatures to match updated version of code.
17820 (consing_since_gc): Now EMACS_INT, since a single hash table can
17821 use more than INT_MAX bytes.
17823 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
17825 Make it possible to build with GCC-4.6+ -O2 -flto.
17827 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
17829 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
17831 * minibuf.c (get_minibuffer, read_minibuf_unwind):
17832 Call minibuffer-inactive-mode.
17834 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
17836 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
17837 Update dependencies.
17839 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17841 * data.c (init_data): Remove code for UTS, this system is not
17844 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17846 Don't force ./temacs to start in terminal mode.
17848 * frame.c (make_initial_frame): Initialize faces in all cases, not
17849 only when CANNOT_DUMP is defined.
17850 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17852 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17854 * dispnew.c (add_window_display_history): Use const for the string
17855 pointer. Remove declaration, not needed.
17857 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17859 Use 'inline', not 'INLINE'.
17860 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17861 * alloc.c, fontset.c (INLINE): Remove.
17862 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17863 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17864 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17865 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17866 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17868 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17870 Make it possible to run ./temacs.
17872 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17873 syms_of_callproc does the same thing. Remove test for
17874 "initialized", do it in the caller.
17875 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17877 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17879 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17880 (read_minibuf): Use get_minibuffer.
17881 (syms_of_minibuf): Use DEFSYM.
17882 (Qmetadata): New var.
17883 * data.c (Qbuffer): Don't make it static.
17884 (syms_of_data): Use DEFSYM.
17886 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17888 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17889 (CCL_CODE_MIN): New macro.
17891 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17893 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17895 * eval.c (Qdebug): Now static.
17896 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17897 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17898 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17900 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17902 * image.c: Various fixes to ImageMagick code comments.
17903 (Fimagemagick_types): Doc fix.
17905 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17907 Minor fixes prompted by GCC 4.6.0 warnings.
17909 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17911 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17912 (x_clipboard_manager_save_all): Move extern decl to ...
17913 * xterm.h: ... here, so that it can be checked for consistency.
17915 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17917 * xselect.c (x_clipboard_manager_save_frame)
17918 (x_clipboard_manager_save_all): New functions.
17919 (Fx_clipboard_manager_save): Lisp function deleted.
17921 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17922 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17924 * xterm.h: Update prototype.
17926 2011-05-28 William Xu <william.xwl@gmail.com>
17928 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17929 exiting (Bug#8239).
17931 2011-05-28 Jim Meyering <meyering@redhat.com>
17933 Avoid a sign-extension bug in crypto_hash_function.
17934 * fns.c (to_uchar): Define.
17935 (crypto_hash_function): Use it to convert some newly-signed
17936 variables to unsigned, to avoid sign-extension bugs. For example,
17937 without this change, (md5 "truc") would evaluate to
17938 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17939 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17940 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17942 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17944 Integer overflow fixes.
17946 * dbusbind.c: Serial number integer overflow fixes.
17947 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17948 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17949 to hold a serial number that is too large for a fixnum.
17950 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17951 Check for serial numbers out of range. Decode any serial number
17952 that was so large that it became a float. (Bug#8722)
17954 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17955 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17956 Use XFASTINT rather than XUINT when numbers are nonnegative.
17957 (xd_append_arg, Fdbus_method_return_internal):
17958 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17959 arguments, check that Lisp number is nonnegative, rather than
17960 silently wrapping negative numbers around. (Bug#8722)
17961 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17964 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17966 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17968 ccl: Add integer overflow checks.
17969 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17970 (IN_INT_RANGE): New macros.
17971 (ccl_driver): Use them to check for integer overflow when
17972 decoding a CCL program. Many of the new checks are whether XINT (x)
17973 fits in int; it doesn't always, on 64-bit hosts. The new version
17974 doesn't catch all possible integer overflows, but it's an
17975 improvement. (Bug#8719)
17977 * alloc.c (make_event_array): Use XINT, not XUINT.
17978 There's no need for unsigned here.
17980 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17981 This follows up to the 2011-05-06 change that substituted uintptr_t
17982 for EMACS_INT. This case wasn't caught back then.
17984 Rework Fformat to avoid integer overflow issues.
17985 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17986 now (part of C89). Include <verify.h>.
17987 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17988 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17989 (Fformat): Avoid the prepass trying to compute sizes; it was only
17990 approximate and thus did not catch overflow reliably. Instead, walk
17991 through the format just once, formatting and computing sizes as we go,
17992 checking for integer overflow at every step, and allocating a larger
17993 buffer as needed. Keep track separately whether the format is
17994 multibyte. Keep only the most-recently calculated precision, rather
17995 than them all. Record whether each argument has been converted to
17996 string. Use EMACS_INT, not int, for byte and char and arg counts.
17997 Support field widths and precisions larger than INT_MAX. Avoid
17998 sprintf's undefined behavior with conversion specifications such as %#d
17999 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
18000 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
18001 formatting out-of-range floating point numbers with int
18002 formats. (Bug#8668)
18004 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
18006 * data.c: Avoid integer truncation in expressions involving floats.
18007 * data.c: Include <intprops.h>.
18008 (arith_driver): When there's an integer overflow in an expression
18009 involving floating point, convert the integers to floating point
18010 so that the resulting value does not suffer from catastrophic
18011 integer truncation. For example, on a 64-bit host (* 4
18012 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
18013 Do not rely on undefined behavior after integer overflow.
18015 merge count_size_as_multibyte, parse_str_to_multibyte
18016 * character.c, character.h (count_size_as_multibyte):
18017 Rename from parse_str_to_multibyte; all uses changed.
18018 Check for integer overflow.
18019 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
18020 since it's now a duplicate of the other. This is more of
18021 a character than a buffer op, so better that it's in character.c.
18022 * fns.c, print.c: Adjust to above changes.
18024 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
18026 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18028 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18030 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18031 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18032 (x_clipboard_manager_save): Now static.
18033 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18035 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18036 (crypto_hash_function): Now static.
18037 Fix pointer signedness problems. Avoid unnecessary initializations.
18039 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18041 * termhooks.h (Vselection_alist): Make it terminal-local.
18043 * terminal.c (create_terminal): Initialize it.
18045 * xselect.c: Support for clipboard managers.
18046 (Vselection_alist): Move to termhooks.h as terminal-local var.
18047 (LOCAL_SELECTION): New macro.
18048 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18049 (symbol_to_x_atom): Remove gratuitous arg.
18050 (x_handle_selection_request, lisp_data_to_selection_data)
18051 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18052 (x_own_selection, x_get_local_selection, x_convert_selection):
18053 New arg, specifying work frame. Use terminal-local Vselection_alist.
18054 (some_frame_on_display): Delete unused function.
18055 (Fx_own_selection_internal, Fx_get_selection_internal)
18056 (Fx_disown_selection_internal, Fx_selection_owner_p)
18057 (Fx_selection_exists_p): New optional frame arg.
18058 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18059 (x_handle_selection_clear): Don't treat other terminals with the
18060 same keyboard specially. Use the terminal-local Vselection_alist.
18061 (x_clear_frame_selections): Use Frun_hook_with_args.
18063 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18065 * xterm.h: Add support for those atoms.
18067 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18069 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18070 (converted_selections, conversion_fail_tag): New global variables.
18071 (x_selection_request_lisp_error): Free the above.
18072 (x_get_local_selection): Remove unnecessary code.
18073 (x_reply_selection_request): Args changed; handle arbitrary array
18074 of converted selections stored in converted_selections.
18075 Separate the XChangeProperty and SelectionNotify steps.
18076 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18077 (x_convert_selection): New function.
18078 (x_handle_selection_event): Simplify.
18079 (x_get_foreign_selection): Don't ignore incoming requests while
18080 waiting for an answer; this will fail when we implement
18081 SAVE_TARGETS, and seems unnecessary anyway.
18082 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18083 (Vx_sent_selection_functions): Doc fix.
18085 2011-05-26 Leo Liu <sdl.web@gmail.com>
18087 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18089 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18091 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18093 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18094 for fringe update if it has periodic bitmap.
18095 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18096 and fringe_bitmap_periodic_p.
18098 * fringe.c (get_fringe_bitmap_data): New function.
18099 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18100 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18101 row. Mark glyph row for fringe update if periodicity changed.
18103 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18104 for fringe update unless it has periodic bitmap.
18106 2011-05-25 Kenichi Handa <handa@m17n.org>
18108 * xdisp.c (get_next_display_element): Set correct it->face_id for
18109 a static composition.
18111 2011-05-24 Leo Liu <sdl.web@gmail.com>
18114 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18116 * fns.c (crypto_hash_function, Fsha1): New function.
18117 (Fmd5): Use crypto_hash_function.
18118 (syms_of_fns): Add Ssha1.
18120 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18122 * gnutls.c: Remove unused macros.
18123 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18124 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18125 Remove macros that are defined and never used.
18126 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18128 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18130 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18131 (Fx_get_selection_internal): Minor cleanup.
18132 (Fx_own_selection_internal): Rename arguments for consistency with
18135 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18137 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18139 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18141 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18143 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18145 * dispnew.c (scrolling_window): Don't exclude the case that the
18146 last enabled row in the desired matrix touches the bottom boundary.
18148 2011-05-21 Glenn Morris <rgm@gnu.org>
18150 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18151 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18152 and add some more files.
18154 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18156 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18157 report_file_error introduced by the change from 2011-05-07.
18159 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18161 * systime.h (Time): Define only if emacs is defined.
18162 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18163 where the include path doesn't have X11/X.h by default. See
18164 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18166 2011-05-20 Kenichi Handa <handa@m17n.org>
18168 * composite.c (find_automatic_composition): Fix previous change.
18170 2011-05-20 Glenn Morris <rgm@gnu.org>
18172 * lisp.mk: New file, split from Makefile.in.
18173 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18174 (shortlisp): Remove.
18175 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18177 2011-05-19 Glenn Morris <rgm@gnu.org>
18179 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18180 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18181 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18182 (lisp): Set the order to that of loadup.el.
18183 (shortlisp): Make it a copy of $lisp.
18184 (SOME_MACHINE_LISP): Remove.
18185 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18186 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18188 2011-05-18 Kenichi Handa <handa@m17n.org>
18190 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18191 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18192 (find_automatic_composition): Mostly rewrite for efficiency.
18194 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18196 * makefile.w32-in: Update dependencies.
18198 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18200 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18201 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18203 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18205 Fix some integer overflow issues, such as string length overflow.
18207 * insdel.c (count_size_as_multibyte): Check for string overflow.
18209 * character.c (lisp_string_width): Check for string overflow.
18210 Use EMACS_INT, not int, for string indexes and lengths; in
18211 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18212 the resulting string length overflows an EMACS_INT; instead,
18213 report a string overflow if no precision given. When checking for
18214 precision exhaustion, use a check that cannot possibly have
18215 integer overflow. (Bug#8675)
18216 * character.h (lisp_string_width): Adjust to new signature.
18218 * alloc.c (string_overflow): New function.
18219 (Fmake_string): Use it. This doesn't change behavior, but saves
18220 a few bytes and will simplify future changes.
18221 * character.c (string_escape_byte8): Likewise.
18222 * lisp.h (string_overflow): New decl.
18224 Fixups, following up to the user-interface timestamp change.
18225 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18226 for UI timestamps, instead of unsigned long.
18227 * msdos.c (mouse_get_pos): Likewise.
18228 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18229 * w32gui.h (Time): Define by including "systime.h" rather than by
18230 declaring it ourselves. (Bug#8664)
18232 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18233 * image.c (clear_image_cache): Likewise.
18235 * term.c (term_mouse_position): Don't assume time_t wraparound.
18237 Be more systematic about user-interface timestamps.
18238 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18239 and sometimes 'EMACS_UINT', to represent these timestamps.
18240 This change causes it to use 'Time' uniformly, as that's what X uses.
18241 This makes the code easier to follow, and makes it easier to catch
18242 integer overflow bugs such as Bug#8664.
18243 * frame.c (Fmouse_position, Fmouse_pixel_position):
18244 Use Time, not unsigned long, for user-interface timestamps.
18245 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18246 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18247 * keyboard.h (last_event_timestamp): Likewise.
18248 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18249 * menu.h (xmenu_show): Likewise.
18250 * term.c (term_mouse_position): Likewise.
18251 * termhooks.h (struct input_event.timestamp): Likewise.
18252 (struct terminal.mouse_position_hook): Likewise.
18253 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18254 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18255 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18256 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18257 what it was before.
18258 * menu.h, termhooks.h: Include "systime.h", for Time.
18260 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18261 Don't assume that the difference between two unsigned long values
18262 can fit into an integer. At this point, we know button_down_time
18263 <= event->timestamp, so the difference must be nonnegative, so
18264 there's no need to cast the result if double-click-time is
18265 nonnegative, as it should be; check that it's nonnegative, just in
18266 case. This bug is triggered when events are more than 2**31 ms
18267 apart (about 25 days). (Bug#8664)
18269 * xselect.c (last_event_timestamp): Remove duplicate decl.
18270 (x_own_selection): Remove needless cast to unsigned long.
18272 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18273 that always fit in int. Use a sentinel instead of a counter, to
18274 avoid a temp and to allay GCC's concerns about possible int overflow.
18275 * frame.h (struct frame): Use int for menu_bar_items_used
18276 instead of EMACS_INT, since it always fits in int.
18278 * menu.c (grow_menu_items): Check for int overflow.
18280 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18282 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18283 Before, the code was not consistent. These values cannot exceed
18284 2**31 - 1 so there's no need to make them unsigned.
18285 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18286 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18287 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18289 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18291 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18292 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18293 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18294 presumably because the widths might not match.
18296 * window.c (size_window): Avoid needless test at loop start.
18298 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18300 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18302 2011-05-12 Drew Adams <drew.adams@oracle.com>
18304 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18306 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18308 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18309 `width' to `bar_area_x' and `bar_area_width', respectively.
18310 (x_scroll_run): Take account of fringe background extension.
18312 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18313 Rename local vars `left' and `width' to `bar_area_x' and
18314 `bar_area_width', respectively.
18315 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18316 background extension.
18318 2011-05-10 Jim Meyering <meyering@redhat.com>
18320 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18322 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18324 * image.c (Finit_image_library): Return t for built-in image types,
18325 like pbm and xbm. (Bug#8640)
18327 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18329 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18331 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18333 * w32console.c (Fset_screen_color): Doc fix.
18334 (Fget_screen_color): New function.
18335 (syms_of_ntterm): Defsubr it.
18337 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18338 unlink the temporary file if Fcall_process didn't create it in the
18340 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18341 child process will be redirected to a file specified with `:file'.
18342 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18343 cue to call_process_cleanup not to close that handle.
18345 2011-05-07 Ben Key <bkey76@gmail.com>
18347 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18348 one of two shell specific rules, either bootstrap-temacs-CMD or
18349 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18350 to the previous implementation of the bootstrap-temacs rule.
18351 The bootstrap-temacs-CMD rule is similar to the previous
18352 implementation of the bootstrap-temacs rule except that it
18353 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18356 These changes, along with some changes to nt/configure.bat,
18357 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18358 earlier fix to add support for --cflags and --ldflags options
18359 that include quotes so that it works whether make uses cmd or
18362 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18364 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18365 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18367 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18368 a string. Handle both cases.
18369 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18370 (Fdbus_register_method): Use Qinvalid_function.
18372 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18374 * makefile.w32-in: Update dependencies.
18375 (LISP_H): Add inttypes.h and stdin.h.
18376 (PROCESS_H): Add unistd.h.
18378 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18380 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18381 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18383 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18385 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18387 * term.c (vfatal): Remove stray call to va_end.
18388 It's not needed and the C Standard doesn't allow it here anyway.
18390 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18391 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18393 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18396 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18398 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18400 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18402 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18404 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18406 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18407 * charset.c (Fdefine_charset_internal): Don't initialize
18408 charset.code_space[15]. The value was garbage, on hosts with
18409 32-bit int (Bug#8600).
18411 * lread.c (read_integer): Be more consistent with string-to-number.
18412 Use string_to_number to do the actual conversion; this avoids
18413 rounding errors and fixes some other screwups. Without this fix,
18414 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18415 (digit_to_number): Move earlier, for benefit of read_integer.
18416 Return -1 if the digit is out of range for the base, -2 if it is
18417 not a digit in any supported base. (Bug#8602)
18419 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18421 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18422 to match comment at start of function. This also removes a
18423 GCC warning about overflow in a 32+64-bit port.
18425 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18427 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18428 Reported by Stefan Monnier in
18429 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18430 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18431 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18433 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18434 (EMACS_UINTPTR): Likewise, with uintptr_t.
18436 * lisp.h: Prefer 64-bit EMACS_INT if available.
18437 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18438 on 32-bit hosts that have 64-bit int, so that they can access
18440 However, temporarily disable this change unless the temporary
18441 symbol WIDE_EMACS_INT is defined.
18443 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18445 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18446 This removes an assumption that EMACS_INT and long are the same
18447 width as pointers. The assumption is true for Emacs porting targets
18448 now, but we want to make other targets possible.
18449 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18450 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18451 In the rest of the code, change types of integers that hold casted
18452 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18453 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18454 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18455 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18456 No need to cast type when ORing.
18457 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18458 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18459 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18460 assume EMACS_INT is the same width as char *.
18461 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18462 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18463 Remove no-longer-needed casts.
18464 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18465 (xg_tool_bar_help_callback, xg_make_tool_item):
18466 Use EMACS_INTPTR to hold an integer
18467 that will be cast to void *; this can avoid a GCC warning
18468 if EMACS_INT is not the same width as void *.
18469 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18470 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18471 (current_message_1, set_message_1):
18472 Use a local to convert to proper width without a cast.
18473 * xmenu.c (dialog_selection_callback): Likewise.
18475 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18476 Also, don't assume VALBITS / RAND_BITS is less than 5,
18477 and don't rely on undefined behavior when shifting a 1 left into
18479 * lisp.h (get_random): Change signature to match.
18481 * lread.c (hash_string): Use size_t, not int, for hash computation.
18482 Normally we prefer signed values; but hashing is special, because
18483 it's better to use unsigned division on hash table sizes so that
18484 the remainder is nonnegative. Also, size_t is the natural width
18485 for hashing into memory. The previous code used 'int', which doesn't
18486 retain enough info to hash well into very large tables.
18487 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18489 * dbusbind.c: Don't possibly lose pointer info when converting.
18490 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18491 Use XPNTR rather than XHASH, so that the high-order bits of
18492 the pointer aren't lost when converting through void *.
18494 * eval.c (Fautoload): Don't double-shift a pointer.
18496 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18498 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18500 * gnutls.c (DEF_GNUTLS_FN):
18501 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18503 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18505 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18508 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18510 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18511 New version that can reserve upto 2GB of heap space.
18513 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18515 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18517 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18519 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18520 `gnutls_certificate_set_x509_key_file'.
18522 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18524 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18525 Update dependencies.
18527 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18529 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18530 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18531 Remove unused parameter `fildes'.
18532 * process.c (read_process_output, send_process): Don't pass it.
18534 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18536 Fix previous change: the library cache is defined in w32.c.
18537 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18538 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18540 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18542 Implement dynamic loading of GnuTLS on Windows.
18544 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18545 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18546 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18549 * gnutls.c (Qgnutls_dll): Define.
18550 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18551 (gnutls_*): Declare function pointers.
18552 (init_gnutls_functions): New function to initialize function pointers.
18553 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
18554 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
18555 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18556 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18557 (emacs_gnutls_write, emacs_gnutls_read)
18558 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18559 (Fgnutls_available_p): New function.
18560 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
18561 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
18562 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18564 * image.c: Include w32.h.
18565 (Vimage_type_cache): Delete.
18566 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
18567 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18568 (w32_delayed_load): Move to w32.c.
18570 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18572 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18573 (w32_delayed_load): Move from image.c. When loading a library, record
18574 its filename in the :loaded-from property of the library id.
18575 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18576 Initialize and staticpro them.
18577 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18579 * process.c: Include lisp.h before w32.h, not after.
18580 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18581 instead of gnutls_record_check_pending.
18583 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18585 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18587 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18588 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18591 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18593 * xterm.c (x_set_frame_alpha): Do not set property on anything
18594 else than FRAME_X_OUTER_WINDOW (Bug#8608).
18596 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18598 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
18600 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18602 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
18603 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

18609 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
18610 (Qgnutls_bootprop_callbacks_verify): Make static.
18612 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
18614 * callproc.c: Indentation fixup.
18616 * sysdep.c (wait_for_termination_1): Make static.
18617 (wait_for_termination, interruptible_wait_for_termination):
18618 Move after wait_for_termination_1.
18620 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18622 * sysdep.c (interruptible_wait_for_termination): New function
18623 which is like wait_for_termination, but allows keyboard
18626 * callproc.c (Fcall_process): Add (:file "file") as an option for
18628 (Fcall_process_region): Ditto.
18630 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18632 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18633 rather than `XVECTOR (FOO)->size'.
18635 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18636 inttypes.h, as a gnulib replacement is used if it not available in
18639 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18641 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18642 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18643 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18645 * coding.c (coding_alloc_by_realloc): Error out if destination
18646 will grow beyond MOST_POSITIVE_FIXNUM.
18647 (decode_coding_emacs_mule): Abort if there isn't enough place in
18648 charbuf for the composition carryover bytes. Reserve an extra
18649 space for up to 2 characters produced in a loop.
18650 (decode_coding_iso_2022): Abort if there isn't enough place in
18651 charbuf for the composition carryover bytes.

18656 aborting when %lld or %lll format is passed.
18657 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
18658 %llo or %llx format is passed. (Bug#8545)
18660 * window.c (window_scroll_line_based): Use a marker instead of
18661 simple variables to record original value of point. (Bug#7952)
18663 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18664 produced by %s or %c overflows available buffer space. (Bug#8545)
18666 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18668 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18669 (SIZE_MAX): Move defn after all includes, as they might #define it.
18671 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18673 * w32.c (init_environment): Warn about defaulting HOME to C:\.
18675 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

18679 if Vdelayed_warnings_list is non-nil.
18680 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
18681 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
18683 2011-04-28 Eli Zaretskii <eliz@gnu.org>
18685 * doprnt.c (doprnt): Don't return value smaller than the buffer
18686 size if the message was truncated. (Bug#8545).
18688 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18690 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
18691 (Fx_window_property): #if-0 the whole functions, not just the bodies.
18693 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18695 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18697 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18699 * makefile.w32-in: Update dependencies.
18701 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18703 Improve `doprnt' and its usage. (Bug#8545)
18704 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18705 `format_end'. Remove support for %l as a conversion specifier.
18706 Don't use xrealloc. Improve diagnostics when the %l size modifier
18707 is used. Update the commentary.
18709 * eval.c (verror): Simplify calculation of size_t.
18711 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18714 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18716 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18719 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18721 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18722 This makes this file independent of the recent pseudovector change.
18724 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18726 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18728 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18729 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18730 Remove unused local.
18731 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18733 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18734 GCC 4.6.0 optimizes based on type-based alias analysis.
18735 For example, if b is of type struct buffer * and v of type struct
18736 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18737 != &v->size, and therefore "v->size = 1; b->size = 2; return
18738 v->size;" must therefore return 1. This assumption is incorrect
18739 for Emacs, since it type-puns struct Lisp_Vector * with many other
18740 types. To fix this problem, this patch adds a new type struct
18741 vectorlike_header that documents the constraints on layout of vectors
18742 and pseudovectors, and helps optimizing compilers not get fooled
18743 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18744 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18745 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18747 (XSETPVECTYPE): Rewrite in terms of new macro.
18748 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18749 This is a bit clearer, and further avoids the possibility of
18750 undesirable aliasing.
18751 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18752 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18753 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18754 since Lisp_Subr is a special case (no "next" field).
18755 (ASIZE): Now uses header.size rather than size.
18756 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18757 to avoid the hassle of writing XVECTOR (foo)->header.size.
18758 (struct vectorlike_header): New type.
18759 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18760 object, to help avoid aliasing.
18761 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18762 (SUBRP): Likewise, since Lisp_Subr is a special case.
18763 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18764 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18765 (struct Lisp_Hash_Table): Combine first two members into a single
18766 struct vectorlike_header member. All uses of "size" and "next" members
18767 changed to be "header.size" and "header.next".
18768 * buffer.h (struct buffer): Likewise.
18769 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18770 * frame.h (struct frame): Likewise.
18771 * process.h (struct Lisp_Process): Likewise.
18772 * termhooks.h (struct terminal): Likewise.
18773 * window.c (struct save_window_data, struct saved_window): Likewise.
18774 * window.h (struct window): Likewise.
18775 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18776 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18777 * buffer.c (init_buffer_once): Likewise.
18778 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18780 * process.c (Fformat_network_address): Use local var for size,
18783 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18785 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18786 * data.c (atof): Remove decl; no longer used or needed.
18787 (digit_to_number): Move to lread.c.
18788 (Fstring_to_number): Use new string_to_number function, to be
18789 consistent with how the Lisp reader treats infinities and NaNs.
18790 Do not assume that floating-point numbers represent EMACS_INT
18791 without losing information; this is not true on most 64-bit hosts.
18792 Avoid double-rounding errors, by insisting on integers when
18793 parsing non-base-10 numbers, as the documentation specifies.
18794 * lisp.h (string_to_number): New decl, replacing ...
18795 (isfloat_string): Remove.
18796 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18797 (read1): Do not accept +. and -. as integers; this
18798 appears to have been a coding error. Similarly, do not accept
18799 strings like +-1e0 as floating point numbers. Do not report
18800 overflow for integer overflows unless the base is not 10 which
18801 means we have no simple and reliable way to continue.
18802 Break out the floating-point parsing into a new
18803 function string_to_number, so that Fstring_to_number parses
18804 floating point numbers consistently with the Lisp reader.
18805 (digit_to_number): Move here from data.c. Make it static inline.
18806 (E_CHAR, EXP_INT): Remove, replacing with ...
18807 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18808 (string_to_number): New function, replacing isfloat_string.
18809 This function checks for valid syntax and produces the resulting
18810 Lisp float number too. Rework it so that string-to-number
18811 no longer mishandles examples like "1.0e+". Use strtoumax,
18812 so that overflow for non-base-10 numbers is reported only when
18813 there's no portable and simple way to convert to floating point.
18815 * textprop.c (set_text_properties_1): Rewrite for clarity,
18816 and to avoid GCC warning about integer overflow.
18818 * intervals.h (struct interval): Use EMACS_INT for members
18819 where EMACS_UINT might cause problems. See
18820 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18821 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18822 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18824 (offset_intervals): Tell GCC not to worry about length overflow
18825 when negating a negative length.
18827 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18828 (overrun_check_free): Likewise.
18830 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18831 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18834 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18835 (gnutls_make_error): Rename local to avoid shadowing.
18836 (gnutls_emacs_global_deinit): ifdef out; not used.
18837 (Fgnutls_boot): Use const for pointer to readonly storage.
18838 Comment out unused local. Fix pointer signedness problems.
18840 * lread.c (openp): Don't stuff size_t into an 'int'.
18841 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18842 about possible signed overflow.
18844 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18845 (GDK_KEY_g): Don't define if already defined.
18846 (xg_prepare_tooltip): Avoid pointer signedness problem.
18847 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18849 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18850 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18852 * xfns.c (Fx_window_property): Simplify a bit,
18853 to make a bit faster and to avoid GCC 4.6.0 warning.
18854 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18856 * fns.c (internal_equal): Don't assume size_t fits in int.
18858 * alloc.c (compact_small_strings): Tighten assertion a little.
18860 Replace pEd with more-general pI, and fix some printf arg casts.
18861 * lisp.h (pI): New macro, generalizing old pEd macro to other
18862 conversion specifiers. For example, use "...%"pI"d..." rather
18863 than "...%"pEd"...".
18864 (pEd): Remove. All uses replaced with similar uses of pI.
18865 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18866 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18867 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18868 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18869 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18870 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18871 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18873 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18874 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18875 * print.c (safe_debug_print, print_object): Likewise.
18876 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18878 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18879 avoiding the 0 flag, which is not portable.
18880 * process.c (Fmake_network_process): Use pI to avoid cast.
18881 * region-cache.c (pp_cache): Likewise.
18882 * xdisp.c (decode_mode_spec): Likewise.
18883 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18884 behavior on 64-bit hosts with printf arg.
18885 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18886 (x_stop_queuing_selection_requests): Likewise.
18887 (x_get_window_property): Don't truncate byte count to an 'int'
18890 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18891 here, since it parses constructs like leading '-' and spaces,
18892 which are not wanted; and it overflows with large numbers.
18893 Instead, simply match F[0-9]+, which is what is wanted anyway.
18895 * alloc.c: Remove unportable assumptions about struct layout.
18896 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18897 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18898 (allocate_vectorlike, make_pure_vector): Use the new macros,
18899 plus offsetof, to remove unportable assumptions about struct layout.
18900 These assumptions hold on all porting targets that I know of, but
18901 they are not guaranteed, they're easy to remove, and removing them
18902 makes further changes easier.
18904 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18905 This doesn't fix a bug but makes the code clearer.
18906 (string_overrun_cookie): Now const. Use initializers that
18907 don't formally overflow signed char, to avoid warnings.
18908 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18909 can cause Emacs to crash when string overrun checking is enabled.
18910 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18911 multiple of sizeof (EMACS_INT); it need not be, if
18912 alignof(EMACS_INT) < sizeof (EMACS_INT).
18913 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18915 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18922 supposed to be handshaking. (Bug#8556)
18923 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18925 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
18927 * lisp.h (Qdebug): List symbol.
18928 * eval.c (Qdebug): Restore global linkage.

18930 (handle_user_signal): Break into debugger when debug-on-event
18931 matches the current signal symbol.
18933 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
18935 * alloc.c (check_sblock, check_string_bytes)
18936 (check_string_free_list): Convert to standard C.
18938 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18940 * w32.c (emacs_gnutls_push): Fix typo.
18942 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18944 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18945 "cast to pointer from integer of different size".
18947 Improve doprnt and its use in verror. (Bug#8545)
18948 * doprnt.c (doprnt): Document the set of format control sequences
18949 supported by the function. Use SAFE_ALLOCA instead of always
18952 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18953 is one byte too soon. Don't use xrealloc; instead xfree and
18956 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18958 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18961 * gnutls.c: Renamed global_initialized to
18962 gnutls_global_initialized. Added internals for the
18963 :verify-hostname-error, :verify-error, and :verify-flags
18964 parameters of `gnutls-boot' and documented those parameters in the
18965 docstring. Start callback support.
18966 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18967 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18968 on error. Return error code.
18969 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18970 (emacs_gnutls_read): Likewise.
18971 (Fgnutls_boot): Return handshake error code.
18972 (emacs_gnutls_handle_error): New function.
18973 (wsaerror_to_errno): Likewise.

19035 <char-direction-table>: Deleted.
19037 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19039 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19040 * doprnt.c: Include limits.h.
19041 (SIZE_MAX): New macro.
19042 (doprnt): Return a size_t value. 2nd arg is now size_t.
19043 Many local variables are now size_t instead of int or unsigned.
19044 Improve overflow protection. Support `l' modifier for integer
19045 conversions. Support %l conversion. Don't assume an EMACS_INT
19046 argument for integer conversions and for %c.
19048 * lisp.h (doprnt): Restore prototype.
19050 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19051 $(SRC)/character.h.
19053 * Makefile.in (base_obj): Add back doprnt.o.
19055 * deps.mk (doprnt.o): Add back prerequisites.
19056 (callint.o): Depend on character.h.
19058 * eval.c (internal_lisp_condition_case): Include the handler
19059 representation in the error message.
19060 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19061 when breaking from the loop.
19063 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19065 * callint.c (Fcall_interactively): When displaying error message
19066 about invalid control letter, pass the character's codepoint, not
19067 a pointer to its multibyte form. Improve display of the character
19068 in octal and display also its hex code.
19070 * character.c (char_string): Use %x to display the (unsigned)
19071 codepoint of an invalid character, to avoid displaying a bogus
19074 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19075 `error', not SYMBOL_NAME itself.
19077 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19078 character arguments to `error'.
19080 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19081 to `error' in error message about FINAL_CHAR argument. Make sure
19082 FINAL_CHAR is a character, and use %c when it is passed as
19083 argument to `error'.

19147 Define only if needed.
19149 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
19150 by pacifying GCC about it. Maybe it's time to retire it?
19151 * xfaces.c (USG, __TIMEVAL__): Likewise.
19153 * dispextern.h (struct redisplay_interface): Rename param
19154 to avoid shadowing.

19202 compatible char. Avoid the old compiler warnings about
19203 out-of-range initializers by using, for example, '\xab' rather
19206 * xgselect.c (xgselect_initialize): Check vs interface
19207 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

19272 * nsfont.m: Fixed bugs in ns_get_family and
19273 ns_descriptor_to_entity that were caused by using free to
19274 deallocate memory blocks that were allocated by xmalloc (via
19275 xstrdup). This caused Emacs to crash when compiled with
19276 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
19277 --enable-checking=xmallocoverrun). xfree is now used to
19278 deallocate these memory blocks.

19292 (emacs_read, emacs_write): Remove check for negative size, as the
19293 Emacs source code has been audited now.
19294 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
19295 (emacs_read, emacs_write): Use it.
19296 * process.c (send_process): Adjust to the new signatures of
19297 emacs_write and emacs_gnutls_write. Do not attempt to store
19298 a byte offset into an 'int'; it might overflow.
19299 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

19633 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
19634 * dispextern.h (bidi_dump_cached_states): Remove, since it's
19635 exported only to the debugger.

19638 * atimer.h (run_all_atimers): Remove; not exported.
19640 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
19641 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
19642 was inaccessible from Lisp.
19643 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
19644 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
19646 alloc.c: Import and export fewer symbols, and remove unused items.
19647 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
19649 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
19650 it's not optimized away by whole-program optimization.

19663 (mark_backtrace): Define only if BYTE_MARK_STACK.
19664 * xdisp.c (message_enable_multibyte): Now static.
19666 Declare Lisp_Object Q* variables to be 'static' if not exported.
19667 This makes it easier for human readers (and static analyzers)
19668 to see whether these variables are used from other modules.
19669 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

19682 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19684 Make Emacs functions such as Fatom 'static' by default.
19685 This makes it easier for human readers (and static analyzers)
19686 to see whether these functions can be called from other modules.
19687 DEFUN now defines a static function. To make the function external
19688 so that it can be used in other C modules, use the new macro DEFUE.

19694 Remove decls, since these functions are now static.
19695 (Funintern, Fget_internal_run_time): New decls, since these functions
19696 were already external.

19709 decls for now-static functions.

19746 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19748 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init

19761 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19762 (overrun_check_free): Protoize.
19764 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19766 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19767 since callers should never pass a negative size.
19768 Change the signature to match that of plain 'read' and 'write'; see
19769 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19770 * lisp.h: Update prototypes of emacs_write and emacs_read.
19772 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19774 * xdisp.c (redisplay_window): Don't try to determine the character
19775 position of the scroll margin if the window start point w->startp
19776 is outside the buffer's accessible region. (Bug#8468)
19778 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19780 Fix write-region and its subroutines for buffers > 2GB.
19781 * fileio.c (a_write, e_write): Modify declaration of arguments and
19782 local variables to support buffers larger than 2GB.
19783 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19785 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19786 argument, local variables, and return value.
19788 * lisp.h: Update prototypes of emacs_write and emacs_read.
19790 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19792 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19794 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19796 Fix more problems found by GCC 4.6.0's static checks.
19798 * xdisp.c (vmessage): Use a better test for character truncation.
19800 * charset.c (load_charset_map): <, not <=, for optimization,
19801 and to avoid potential problems with integer overflow.
19802 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19803 * casetab.c (set_identity, shuffle): Likewise.
19804 * editfns.c (Fformat): Likewise.
19805 * syntax.c (skip_chars): Likewise.
19807 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19808 This also lets GCC 4.6.0 generate slightly better loop code.
19810 * callint.c (Fcall_interactively): <, not <=, for optimization.
19811 (Fcall_interactively): Count the number of arguments produced,
19812 not the number of arguments given. This is simpler and lets GCC
19813 4.6.0 generate slightly better code.
19815 * ftfont.c: Distingish more carefully between FcChar8 and char.
19816 The previous code passed unsigned char * to a functions like
19817 strlen and xstrcasecmp that expect char *, which does not
19818 conform to the C standard.
19819 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19820 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19821 char * when the C standard requires it.
19823 * keyboard.c (read_char): Remove unused var.
19825 * eval.c: Port to Windows vsnprintf (Bug#8435).
19826 Include <limits.h>.
19827 (SIZE_MAX): Define if the headers do not.
19828 (verror): Do not give up if vsnprintf returns a negative count.
19829 Instead, grow the buffer. This ports to Windows vsnprintf, which
19830 does not conform to C99. Problem reported by Eli Zaretskii.
19831 Also, simplify the allocation scheme, by avoiding the need for
19832 calling realloc, and removing the ALLOCATED variable.
19834 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19836 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19837 But keep the doprint source code for now, as we might revamp it
19838 and use it again (Bug#8435).
19839 * lisp.h (doprnt): Remove.
19840 * Makefile.in (base_obj): Remove doprnt.o.
19841 * deps.mk (doprnt.o): Remove.
19843 error: Print 32- and 64-bit integers portably (Bug#8435).
19844 Without this change, on typical 64-bit hosts error ("...%d...", N)
19845 was used to print both 32- and 64-bit integers N, which relied on
19846 undefined behavior.
19847 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19848 * lisp.h (error, verror): Mark as printf-like functions.
19849 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19850 Report overflow in size calculations when allocating printf buffer.
19851 Do not truncate output string at its first null byte.
19852 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19853 Truncate the output at a character boundary, since vsnprintf does not
19855 * charset.c (check_iso_charset_parameter): Convert internal
19856 character to string before calling 'error', since %c now has the
19858 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19859 overflow when computing char to be passed to 'error'. Do not
19860 pass Lisp_Object to 'error'; pass the integer instead.
19861 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19862 formatted with plain %d.
19864 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19866 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19868 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19870 * xterm.c (x_catch_errors): Remove duplicate declaration.
19872 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19874 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19876 2011-04-10 Jim Meyering <meyering@redhat.com>
19878 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19879 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19880 return ssize_t not "int", and use size_t as the buffer length.
19881 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19882 * gnutls.h: Update declarations.
19883 * process.c (read_process_output): Use ssize_t, to match.
19884 (send_process): Likewise.
19886 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19888 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19890 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19892 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19893 Use unsigned char, to match FcChar8 type definition.
19895 * xterm.c (handle_one_xevent):
19896 * xmenu.c (create_and_show_popup_menu):
19897 * xselect.c (x_decline_selection_request)
19898 (x_reply_selection_request): Avoid type-punned deref of X events.
19900 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19902 Fix some uses of `int' instead of EMACS_INT.
19903 * search.c (string_match_1, fast_string_match)
19904 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19905 (scan_buffer, find_next_newline_no_quit)
19906 (find_before_next_newline, search_command, Freplace_match)
19907 (Fmatch_data): Make some `int' variables be EMACS_INT.
19909 * xdisp.c (display_count_lines): 3rd argument and return value now
19910 EMACS_INT. All callers changed.
19911 (pint2hrstr): Last argument is now EMACS_INT.
19913 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19914 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19915 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

19929 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19930 (encode_invocation_designation): Last argument P_NCHARS is now
19932 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19933 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19935 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19938 * ccl.c (Fccl_execute_on_string): Declare some variables
19941 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19943 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19945 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19947 * process.c (Fformat_network_address): Doc fix.
19949 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19951 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19953 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19955 * keyboard.c (read_char): Call Lisp function help-form-show,
19956 instead of using internal_with_output_to_temp_buffer.
19957 (Qhelp_form_show): New var.
19958 (syms_of_keyboard): Use DEFSYM macro.
19960 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19969 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19971 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19973 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19975 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19977 Fix more problems found by GCC 4.6.0's static checks.

19999 This avoids several warnings with gcc -Wstrict-overflow.
20000 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
20001 directly, rather than having caller test rule sign. This avoids
20002 some unnecessary tests.
20003 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
20004 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
20005 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
20007 * xfont.c (xfont_text_extents): Remove var that was set but not used.
20008 (xfont_open): Avoid unnecessary tests.
20010 * composite.c (composition_gstring_put_cache): Use unsigned integer.
20012 * composite.h, composite.c (composition_gstring_put_cache):
20013 Use EMACS_INT, not int, for length.
20015 * composite.h (COMPOSITION_DECODE_REFS): New macro,
20016 breaking out part of COMPOSITION_DECODE_RULE.
20017 (COMPOSITION_DECODE_RULE): Use it.
20018 * composite.c (get_composition_id): Remove unused local vars,
20019 by using the new macro.
20021 * textprop.c (set_text_properties_1): Change while to do-while,
20022 since the condition is always true at first.
20024 * intervals.c (graft_intervals_into_buffer): Mark var as used.
20025 (interval_deletion_adjustment): Return unsigned value.
20028 * process.c (list_processes_1, create_pty, read_process_output):
20029 (exec_sentinel): Remove vars that were set but not used.
20030 (create_pty): Remove unnecessary "volatile"s.
20031 (Fnetwork_interface_info): Avoid possibility of int overflow.
20032 (read_process_output): Do adaptive read buffering even if carryover.
20033 (read_process_output): Simplify nbytes computation if buffered.

20044 * print.c (print_error_message): Avoid int overflow.
20046 * font.c (font_list_entities): Redo for clarity,
20047 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
20049 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
20050 (font_score): Avoid potential overflow in diff calculation.

20053 (sxhash): Redo loop for clarity and to avoid wraparound warning.
20055 * eval.c (funcall_lambda): Rename local to avoid shadowing.
20057 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
20058 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
20059 can always succeed if overflow has undefined behavior.
20061 * search.c (boyer_moore, wordify): Remove vars set but not used.
20062 (wordify): Omit three unnecessary tests.
20064 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
20065 All callers changed. This avoids the need for an unused var.
20067 * casefiddle.c (casify_region): Remove var that is set but not used.
20069 * dired.c (file_name_completion): Remove var that is set but not used.
20071 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20073 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
20074 (Finsert_file_contents): Remove unnecessary code checking fd.
20076 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20077 Check for integer overflow on size calculations.
20079 * buffer.c (Fprevious_overlay_change): Remove var that is set
20082 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20083 Remove vars that are set but not used.
20084 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20085 (timer_check_2): Mark vars as initialized.
20087 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20089 * image.c (lookup_image): Remove var that is set but not used.
20090 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20092 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20093 that are set but not used.
20095 * xfns.c (make_invisible_cursor): Don't return garbage
20096 if XCreateBitmapFromData fails (Bug#8410).
20098 * xselect.c (x_get_local_selection, x_handle_property_notify):
20099 Remove vars that are set but not used.
20101 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20102 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20104 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20105 Remove var that is set but not used.
20106 (scroll_bar_windows_size): Now size_t, not int.
20107 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20108 Check for overflow.
20110 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20111 (map_tty_color) [!defined MSDOS]: Likewise.
20113 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20115 * coding.c: Remove vars that are set but not used.
20116 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20117 All callers changed.
20118 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20119 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20120 (decode_coding_charset): Remove vars that are set but not used.
20122 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20123 that is set but not used.
20125 * print.c (print_object): Remove var that is set but not used.
20127 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20128 The gnulib version avoids calling malloc in the usual case,
20129 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20130 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20131 * filelock.c (current_lock_owner): Likewise.
20132 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20133 * sysdep.c: Include allocator.h, careadlinkat.h.
20134 (emacs_no_realloc_allocator): New static constant.
20135 (emacs_readlink): New function.
20136 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20137 ../lib/careadlinkat.h.
20139 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20141 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20142 first non-nil return value).
20144 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
20146 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
20147 if not defined (Bug#8403).
20149 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20151 * xdisp.c (display_count_lines): Remove parameter `start',
20152 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20153 (get_char_face_and_encoding): Remove parameter `multibyte_p',
20154 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

20156 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
20157 and thereabouts. All callers changed.
20158 (get_per_char_metric): Remove parameter `f', unused since
20159 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
20161 2011-04-02 Jim Meyering <meyering@redhat.com>
20163 do not dereference NULL upon failed strdup
20164 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20165 (ns_get_family): Likewise.
20167 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20169 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20171 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20173 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20176 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20178 Add lexical binding.
20180 * window.c (Ftemp_output_buffer_show): New fun.
20181 (Fsave_window_excursion):
20182 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20184 * lread.c (lisp_file_lexically_bound_p): New function.
20185 (Fload): Bind Qlexical_binding.
20186 (readevalloop): Remove `evalfun' arg.
20187 Bind Qinternal_interpreter_environment.
20188 (Feval_buffer): Bind Qlexical_binding.
20189 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20191 (syms_of_lread): Declare `lexical-binding'.
20193 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20195 * keyboard.c (eval_dyn): New fun.
20196 (menu_item_eval_property): Use it.
20198 * image.c (parse_image_spec): Use Ffunctionp.
20200 * fns.c (concat, mapcar1): Accept byte-code-functions.
20202 * eval.c (Fsetq): Handle lexical vars.
20203 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20204 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20205 (FletX, Flet): Obey lexical binding.
20206 (Fcommandp): Handle closures.
20207 (Feval): New `lexical' arg.
20208 (eval_sub): New function extracted from Feval. Use it almost
20209 everywhere where Feval was used. Look up vars in lexical env.
20211 (Ffunctionp): Move from subr.el.
20212 (Ffuncall): Handle closures.
20213 (apply_lambda): Remove `eval_flags'.
20214 (funcall_lambda): Handle closures and new byte-code-functions.
20215 (Fspecial_variable_p): New function.
20216 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20217 but without exporting it to Lisp.
20219 * doc.c (Fdocumentation, store_function_docstring):
20220 * data.c (Finteractive_form): Handle closures.
20222 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20225 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20227 (exec_byte_code): New function extracted from Fbyte_code to handle new
20228 calling convention for byte-code-functions. Add new byte-codes.
20230 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20232 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20234 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20236 * xdisp.c (redisplay_internal): Fix prototype.
20238 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20240 * xdisp.c (SCROLL_LIMIT): New macro.
20241 (try_scrolling): Use it when setting scroll_limit.
20242 Limit scrolling to 100 screen lines.
20243 (redisplay_window): Even when falling back on "recentering",
20244 position point in the window according to scroll-conservatively,
20245 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20247 (try_scrolling): When point is above the window, allow searching
20248 as far as scroll_max, or one screenful, to compute vertical
20249 distance from PT to the scroll margin position. This prevents
20250 try_scrolling from unnecessarily failing when
20251 scroll-conservatively is set to a value slightly larger than the
20252 window height. Clean up the case of PT below the margin at bottom
20253 of window: scroll_max can no longer be INT_MAX. When aggressive
20254 scrolling is in use, don't let point enter the opposite scroll
20255 margin as result of the scroll.
20256 (syms_of_xdisp) <scroll-conservatively>: Document the
20257 threshold of 100 lines for never-recentering scrolling.
20259 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20261 * dispextern.h (move_it_by_lines):
20262 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

20264 (message_log_check_duplicate): Remove parameters `prev_bol' and
20265 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20266 (redisplay_internal): Remove parameter `preserve_echo_area',
20267 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20269 * indent.c (Fvertical_motion):
20270 * window.c (window_scroll_pixel_based, Frecenter):
20271 Don't pass `need_y_p' to `move_it_by_lines'.
20273 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20275 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20276 steal a few bits to be more compact.
20277 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20278 Remove unneeded casts.
20280 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20282 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20284 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20285 binding" message (bug#7967).
20287 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20289 Fix more problems found by GCC 4.6.0's static checks.
20291 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20292 Remove unused local var.
20294 * editfns.c (Fmessage_box): Remove unused local var.
20296 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20297 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20298 Omit unused local vars.
20299 * window.c (shrink_windows): Omit unused local var.
20300 * menu.c (digest_single_submenu): Omit unused local var.
20301 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20302 Omit unused local var.
20304 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20305 Don't assume string length fits in int.
20306 (keyremap_step, read_key_sequence): Use size_t for sizes.
20307 (read_key_sequence): Don't check last_real_key_start redundantly.
20309 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20310 instead of alloca (Bug#8344).
20312 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20313 (Fbacktrace_frame): Don't assume nframes fits in int.
20315 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20317 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20320 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20322 * cm.c (calccost): Turn while-do into do-while, for clarity.
20324 * keyboard.c (syms_of_keyboard): Use the same style as later
20325 in this function when indexing through an array. This also
20326 works around GCC bug 48267.
20328 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20330 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20332 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20333 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20335 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20336 This avoids undefined behavior on integer overflow, and is a bit
20337 more convenient anyway since it is compared to a size_t variable.
20339 Variadic C functions now count arguments with size_t, not int.
20340 This avoids an unnecessary limitation on 64-bit machines, which
20341 caused (substring ...) to crash on large vectors (Bug#8344).
20342 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
20343 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

20351 * fns.c (concat): Likewise.
20352 * frame.c (x_set_frame_parameters): Likewise.
20353 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20354 0 if not found, not -1. All callers changed.
20356 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20357 (stack_copy_size): Now size_t, not int.
20358 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20360 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20362 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20363 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20364 All callers changed.
20366 * lisp.h (multibyte_char_to_unibyte):
20367 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
20368 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

20379 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20380 don't set the hook to nil, but remove the offending function instead.
20381 (Qcommand_hook_internal): Remove, unused.
20382 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20383 Vcommand_hook_internal.
20385 * eval.c (enum run_hooks_condition): Remove.
20386 (funcall_nil, funcall_not): New functions.
20387 (run_hook_with_args): Call each function through a `funcall' argument.

20401 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20402 All callers changed.
20404 * w32.c (_wsa_errlist): Use braces for struct initializers.
20406 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
20407 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
20408 All callers changed.

20563 * buffer.c (Fkill_all_local_variables):
20564 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20566 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20567 unconditionally since it does the check itself.
20569 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20571 Fix more problems found by GCC 4.5.2's static checks.
20573 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20574 the first time through the loop, since we know p0 < p1 then.
20575 This also avoids a gcc -Wstrict-overflow warning.
20577 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20578 leading to a memory leak, possible in functions like
20579 load_charset_map_from_file that can allocate an unbounded number
20580 of objects (Bug#8318).
20582 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20583 that could (at least in theory) be that large.
20585 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20586 This is less likely to overflow, and avoids undefined behavior if
20587 overflow does occur. All callers changed. Use strtoul to scan
20588 for the unsigned long integer.
20589 (pint2hrstr): Simplify and tune code slightly.
20590 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20605 * process.c (Fmake_network_process): Use socklen_t, not int,
20606 where POSIX says socklen_t is required in portable programs.
20607 This fixes a porting bug on hosts like 64-bit HP-UX, where
20608 socklen_t is wider than int (Bug#8277).
20609 (Fmake_network_process, server_accept_connection):
20610 (wait_reading_process_output, read_process_output):
20613 * process.c: Rename or move locals to avoid shadowing.

20623 Make tparam.h and terminfo.c consistent.
20624 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20625 Include tparam.h instead, since it declares them.
20626 * cm.h (PC): Remove extern decl; tparam.h now does this.
20627 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20628 * terminfo.c: Include tparam.h, to check interfaces.
20629 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20630 (tparam): Adjust signature to match interface in tparam.h;
20631 this removes some undefined behavior. Check that outstring and len
20632 are zero, which they always are with Emacs.
20633 * tparam.h (PC, BC, UP): New extern decls.
20635 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20636 (xftfont_open): Rename locals to avoid shadowing.

20653 (find_automatic_composition, composition_adjust_point): Likewise.
20654 (composition_update_it): Mark var as initialized.
20655 (find_automatic_composition): Mark vars as initialized,
20656 with a FIXME (Bug#8290).

20660 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20661 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20662 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20663 to avoid shadowing.
20665 * textprop.c (property_change_between_p): Remove; unused.
20667 * intervals.c (interval_start_pos): Now static.
20669 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

20675 Fix pointer signedness.
20676 (alsa_choose_format): Remove unused local var.
20677 (wav_play): Initialize a variable to 0, to prevent undefined
20678 behavior (Bug#8278).
20680 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20682 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20684 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20685 clobbering (Bug#8298).
20686 * sysdep.c (sys_subshell): Likewise.
20687 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20689 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20690 This should get cleaned up, so that child_setup has the
20691 same signature on all platforms.
20693 * callproc.c (call_process_cleanup): Now static.
20694 (relocate_fd): Rename locals to avoid shadowing.
20696 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20698 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20699 not to be necessary, and produces flickering.
20701 2011-03-20 Glenn Morris <rgm@gnu.org>
20703 * config.in: Remove file.
20705 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20707 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20708 are now in src/globals.h.

20735 (sigchld_handler): Now static.
20737 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
20738 That way, the code declares only the vars that it needs.

20749 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
20750 Define only if needed.
20752 * unexelf.c (unexec): Name an expression,
20753 to avoid gcc -Wbad-function-cast warning.
20754 Use a different way to cause a compilation error if anyone uses
20755 n rather than nn, a way that does not involve shadowing.
20756 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20758 * deps.mk (unexalpha.o): Remove; unused.
20760 New file unexec.h, the (simple) interface for unexec (Bug#8267).

20827 (Ftranslate_region_internal, Fformat):
20828 Rename or remove local vars to avoid shadowing.

20831 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
20834 * lisp.h (eassert): Check that the argument compiles, even if
20835 ENABLE_CHECKING is not defined.
20837 * data.c (Findirect_variable): Name an expression, to avoid
20838 gcc -Wbad-function-cast warning.

20855 (Fmemory_limit): Cast sbrk's returned value to char *.

20881 (RETALLOC_IF): Define only if needed.
20882 (WORDCHAR_P): Likewise. This one is never needed, but is used
20883 only in a comment talking about a compiler bug, so put inside
20884 the #if 0 of that comment.

20914 gcpro1, gcpro2, etc.
20915 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20917 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second

20922 Rename locals to avoid shadowing.
20924 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

20933 (downcase, upcase1): New static inline functions.
20934 (DOWNCASE, UPCASE1): Reimplement using these functions.
20935 This avoids undefined behavior in expressions like

20966 so that gcc does not warn that these functions aren't declared.

20969 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

20976 * buffer.c (fix_overlays_before): Mark locals as initialized.
20977 (fix_start_end_in_overlays): Likewise. This function should be
20978 simplified by using pointers-to-pointers, but that's a different

20982 (report_overlay_modification): Rename locals to avoid shadowing.

20987 to suppress a gcc -Wclobbered warning that does not seem to be right.
20988 (MAXPATHLEN): Define only if needed.
20990 * process.c (serial_open, serial_configure): Move decls from here ...
20991 * systty.h: ... to here, so that they can be checked.
20993 * fns.c (get_random, seed_random): Move extern decls from here ...

21337 a block, when the outer 'i' will do.

21350 -Wuninitialized does not deduce are never used uninitialized.
21351 (detect_coding_iso_2022): Initialize a local variable that might
21352 be used uninitialized. Leave a FIXME because it's not clear that
