26 Avoid unnecessary byte position calculation for the gap movement.
27 Since all users of move_gap do CHAR_TO_BYTE for other purposes
28 anyway, all of them should use move_gap_both instead.

30 * insdel.c (move_gap): Remove.
31 (move_gap_both): Add eassert.
32 * editfns.c (Ftranspose_regions): Tweak to use move_gap_both.

40 * term.c (init_tty): Use them instead of rolling our own code.
41 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
42 switches from 'signal' to 'pthread_sigmask', which is safer in
43 multithreaded applications.
44 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
45 which has already arranged for that.
46 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
47 This is the main part of the bug fix.
49 2013-01-10 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)
51 * gtkutil.c (xg_initialize): Add ifdef HAVE_FREETYPE around

61 * buffer.c (buffer_slot_type_mismatch): Remove.
62 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
63 predicate. Adjust comment.

68 Use Qstringp for default-directory, buffer-file-name,
69 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
70 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
72 * data.c (store_symval_forwarding): Adjust to call the predicate.
74 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
76 * w32.c (get_name_and_id, acl_set_file):

90 * coding.c (coding_alloc_by_making_gap): Use it.
91 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
92 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
94 2013-01-08 Juri Linkov <juri@jurta.org>
96 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
97 of (supports :underline (:style wave)). (Bug#13000)

108 2013-01-06 Chong Yidong <cyd@gnu.org>
110 * keyboard.c (echo_add_char): New function, factored out from

115 trailing dash is properly added.
117 2013-01-05 Eli Zaretskii <eliz@gnu.org>
119 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
120 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
121 digits for buffer positions, before misalignment starts.
122 Display "0" for integer "object" field.
123 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
124 Display the newline glyph more unambiguously.
126 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
128 * nsterm.m (ns_draw_underwave):
129 * w32term.c (w32_draw_underwave):
130 * xterm.c (x_draw_underwave): Make underwave look more triangular
131 and also degrade gracefully for small fonts. (Bug#13000)
133 * nsterm.m (ns_draw_text_decoration):
134 * w32term.c (x_draw_glyph_string):
135 * xterm.c (x_draw_glyph_string): Don't use previous underline
136 thickness and position if previous underline type is underwave.
138 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
140 * fileio.c (Ffile_acl): Undocument return format.
142 2013-01-02 Glenn Morris <rgm@gnu.org>
144 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
146 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>
149 * dired.c (file_name_completion):
150 * doc.c (get_doc_string):
151 * floatfns.c (round2):
152 * font.c (font_score, font_delete_unmatched):
153 * fringe.c (compute_fringe_widths):
154 * lread.c (read_list):
155 * minibuf.c (Ftry_completion):
156 * term.c (tty_ins_del_lines):
157 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
158 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
160 2012-12-31 Eli Zaretskii <eliz@gnu.org>
162 * w32.c (unsetenv): Set up the string passed to _putenv
164 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
165 for the bug this caused.
167 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
169 * coding.c (Qmac): Now static.
171 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
173 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
174 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
175 handlebox_widget. Set toolbar_in_hbox to false/true, set
176 toolbar_is_packed to true.
177 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
178 (update_frame_tool_bar): Check toolbar_is_packed for packing.
179 Show all on TOOLBAR_TOP_WIDGET.
180 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned

182 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
183 Check toolbar_is_packed.
184 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
185 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
186 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
188 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
189 (xg_update_menubar): Update title only if
190 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
191 (xg_update_submenu): Skip tearoff only if
192 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
193 (xg_initialize): Initialize xg_detached_menus only if
194 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
196 * xterm.h (struct x_output): Surround handlebox_widget with
197 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
198 toolbar_in_hbox is bool.
200 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
202 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
203 (LIBS_GNUSTEP): Define.
204 (LIBES): Add $(LIBS_GNUSTEP).
205 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
207 2012-12-30 Eli Zaretskii <eliz@gnu.org>
209 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
210 continuation glyph on a TTY with an indication of an empty line.
213 2012-12-29 Eli Zaretskii <eliz@gnu.org>
215 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
216 file's SELinux context or ACLs successfully set, nil otherwise.
218 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
220 * w32proc.c (reader_thread): Avoid passing NULL handles to
221 SetEvent and WaitForSingleObject.
223 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
225 Port EXTERNALLY_VISIBLE to Clang 3.2.
226 * conf_post.h (__has_attribute): New macro.
227 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
229 2012-12-27 Glenn Morris <rgm@gnu.org>
231 * cygw32.c (Fcygwin_convert_file_name_to_windows)
232 (Fcygwin_convert_file_name_from_windows): Doc fixes.
234 2012-12-27 Eli Zaretskii <eliz@gnu.org>
236 * fileio.c (file_name_as_directory, directory_file_name):
237 Accept an additional argument MULTIBYTE to indicate whether the input C
238 came from a multibyte or a unibyte Lisp string; all callers
239 adjusted. Don't assume the input string is always multibyte.
241 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
242 don't ENCODE_FILE them, and return a unibyte string if the input
244 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
245 don't assume the input strings will always be multibyte. If the
246 input strings are multibyte, decode strings obtained from C
249 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
251 * lisp.h (toplevel): Add two notices to the comment about
252 defining a new Lisp data type.
253 * print.c (print_object): If Lisp_Save_Value object's pointer
254 is the address of a memory area containing Lisp_Objects, try
256 * alloc.c (valid_lisp_object_p): Adjust comment.
258 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
260 * keyboard.c (record_asynch_buffer_change): Initialize an event
261 only if it's really needed.
262 * frame.h (enum output_method): Remove output_mac member since
263 it's a leftover from the deleted code.
264 * frame.c (Fframep): Adjust user here ...
265 * terminal.c (Fterminal_live_p): ... and here.
266 * coding.c (Qmac): Now here because it's only used to denote
267 end-of-line encoding type.
268 (syms_of_coding): DEFSYM it.
269 * frame.h (Qmac): Remove duplicated declaration.
271 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
273 * window.c (select_window_1): Now static, since it's used only here.
275 2012-12-25 Eli Zaretskii <eliz@gnu.org>
277 * window.c (window_body_cols): Subtract display margins from the
278 window body width on TTYs as well. See
279 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
280 for the original report.
282 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
284 * xdisp.c (redisplay_window): Remove inner local variable
285 because the outer shadowed one has the same meaning.
286 * xterm.h (struct x_output): Remove toolbar_detached member since it's
288 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
289 (xg_create_tool_bar): Adjust users.
291 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
293 * buffer.h (BUF_COMPACT): New macro to follow the common style.
294 * buffer.c (Fget_buffer_create): Use it to set compact field of
295 struct buffer_text to avoid accessing an uninitialized value
296 when compact_buffer is called for the first time.
297 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
298 (Fset_buffer_modified_p): Use buffer_window_count to check
299 whether the buffer is displayed in some window.
300 * xdisp.c (message_dolog): Likewise.
302 2012-12-23 Eli Zaretskii <eliz@gnu.org>
304 * w32.c (acl_set_file): If setting the file security descriptor
305 fails, and the new DACL is identical to the existing one, silently
306 return success. This fixes problems for users backing up their
307 own files without having the necessary privileges for setting
308 security descriptors.
310 * w32proc.c (reader_thread): Do not index fd_info[] with negative
312 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
313 after WaitForSingleObject returns normally. This expedites reader
314 thread shutdown when delete_child triggers it.
315 (reap_subprocess): More accurate commentary for why we call
316 delete_child only when cp->fd is negative.
318 * w32.c (sys_close): Do not call delete_child on a subprocess
319 whose handle is not yet closed. Instead, set its file descriptor
320 to a negative value, so that reap_subprocess will call
321 delete_child on that subprocess when its SIGCHLD arrives.
322 This avoids closing handles used for communications between sys_select
323 and reader_thread, which doesn't give sys_select a chance to
324 notice that the process exited and invoke the SIGCHLD handler for
327 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
329 * nsfns.m (Fns_do_applescript): Run event loop until script has
330 been executed (Bug#12969).
331 (ns_run_ascript): Chech as_script for nil, set to nil after
334 2012-12-22 Martin Rudalics <rudalics@gmx.at>
336 * window.c (Fselect_window): Reword doc-string (Bug#13248).

340 * w32term.c (w32fullscreen_hook): New function.
341 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
343 2012-12-21 Eli Zaretskii <eliz@gnu.org>
345 * fileio.c (Finsert_file_contents): Doc fix.
347 * w32proc.c (new_child, delete_child, find_child_pid): For a
348 subprocess, consider its slot being in use as long as its process
349 handle (procinfo.hProcess) is not NULL. This avoids reusing the
350 slot when a new process is started immediately after killing
351 another one, without waiting enough time for the first process to
352 be reaped and resources allocated for it be orderly freed.
354 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
356 2012-12-21 Chong Yidong <cyd@gnu.org>
358 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
360 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
362 2012-12-21 Eli Zaretskii <eliz@gnu.org>
364 * w32.c (get_name_and_id): Always pass NULL as the first argument
365 of lookup_account_sid. Avoids crashes with UNC file names that
366 refer to DFS domains, not to specific machine names. (Bug#12621)
367 Remove now unused argument FNAME; all callers changed.
368 (get_file_owner_and_group): Remove now unused argument FNAME; all
371 2012-12-21 Chong Yidong <cyd@gnu.org>
373 * editfns.c (Finsert_char): Since read-char-by-name now signals an
374 error for invalid chars, don't check for a nil return value.
376 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
378 Avoid calls to CHAR_TO_BYTE if byte position is known.
379 * editfns.c (make_buffer_string_both): Use move_gap_both.
380 (Fbuffer_string): Use make_buffer_string_both.
381 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
383 (buf_bytepos_to_charpos): Likewise.
384 (charpos_to_bytepos): Remove.
385 * fileio.c (Finsert_file_contents): Use move_gap_both.
386 * search.c (Freplace_match): Likewise.
387 * process.c (process_send_region): Likewise. Use convenient
388 names for byte positions.
389 * lisp.h (charpos_to_bytepos): Remove prototype.
390 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
391 * insdel.c (move_gap): Likewise.

400 (redisplay_internal): Don't bother selecting the frame to get the
401 proper value of frame-local variables (bug#13225).
403 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
405 * textprop.c (set_text_properties_1): Do not allow NULL interval.
406 Rename 4th argument since it may be buffer or string. Adjust comment.
407 * intervals.c (graft_intervals_info_buffer): Find an interval here.
409 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
411 * coding.c (Fdetect_coding_region): Do not check start and end with
412 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
413 (code_convert_region): Likewise.
415 2012-12-18 Eli Zaretskii <eliz@gnu.org>
417 * w32.c (acl_get_file, acl_set_file): Run the file name through
418 map_w32_filename, and resolve any symlinks in the file name, like
420 (acl_set_file): Call revert_to_self, if any privileges were
423 2012-12-17 Juanma Barranquero <lekktu@gmail.com>

426 ($(BLD)/w32.$(O)): Update dependencies.
428 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
430 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
431 propagate redisplay's scrolling (if any) to the right window.
432 (redisplay_internal): Use ensure_selected_frame.
433 (display_mode_lines): Complete last fix.
434 * window.c (select_window_1): New func, extracted from select_window.
435 (select_window): Use it.
436 * window.h (select_window_1): Declare.

462 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
464 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
465 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
466 for some of that bug's symptoms can now cause Emacs to abort.
467 Remove the workaround.
468 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
469 The bug that caused SIGCHLD to get lost has been fixed, and the
470 workaround for it can now cause Emacs to abort.
472 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
474 * sysdep.c (emacs_abort): Bump backtrace size to 40.
475 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
476 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

498 (record_infile, record_pending_deletion): New prototypes.
500 * w32proc.c (new_child): Initialize input_file and
501 pending_deletion members of the child.
502 (delete_child): Delete the child's temporary input file, if any,
503 that is pending deletion.
504 (register_child): First argument is now pid_t.
505 (record_infile, record_pending_deletion): New functions.
506 (reap_subprocess): Fix a typo in DebPrint string.
507 (sys_spawnve, sys_kill): Use pid_t for PID arguments.

514 * callproc.c (Fcall_process): Don't overwrite infile with result
516 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
517 asynchronous subprocess, record the name of the input file name,
519 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
520 delete the file, record it as pending deletion when the subprocess

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

545 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
546 try to get accurate owner and group information from NT file
547 security APIs. This is to make most callers of 'stat' and
548 'lstat', which don't need that information, much faster.
550 * dired.c (Ffile_attributes) [WINDOWSNT]:
551 Set w32_stat_get_owner_group to a non-zero value, to request accurate
552 owner and group information from 'lstat'.
554 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
556 * fileio.c (Finsert_file_contents): Don't put tail into head area,
557 as that confuses set-auto-coding, so insist on the head-read
558 returning the full 1024 bytes. Let lseek compute the tail offset;
559 less work for us. Do not ignore I/O errors when reading the tail.
561 * xdisp.c: Minor style fixes.
562 (init_iterator): Hoist assignment out of if-expression.
563 (markpos_of_region): Callers now test for sign, not for -1.

586 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
588 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
589 fstat shouldn't fail, and if it does fail copy-file should not proceed.
590 Remove unnecessary S_ISLNK test, as (contra the comments) this
591 function can't copy symlinks. Improve quality of error message
592 when attempting to copy files that are neither regular files nor

603 2012-12-12 Daniel Colascione <dancol@dancol.org>
605 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
606 the dumped Emacs is not a sparse file, greatly improving Cygwin

616 * xdisp.c (handle_face_prop): Fix logic of computing
617 it->start_of_box_run_p.
618 (append_space_for_newline): If the glyph row is R2L, reset the
619 iterator's end_of_box_run_p flag before prepending the space glyph.
620 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
621 iterator's start_of_box_run_p flag before prepending the stretch.
622 (append_glyph, produce_image_glyph, append_composite_glyph)
623 (append_stretch_glyph, append_glyphless_glyph): Reverse the
624 left_box_line_p and right_box_line_p flags of the glyph for R2L
625 glyph rows. (Bug#13011)
627 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>

637 2012-12-11 Eli Zaretskii <eliz@gnu.org>
639 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
640 encoded_file_name, which is what it is.
642 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
644 Consistently use marker_position and marker_byte_position.

665 * w32term.c, keyboard.c: Fix build break in cygw32 by omitting
666 Windows file notification functionality unless WINDOWSNT.
668 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
671 * w32fns.c (cache_system_info): Initialize the global hinst

675 (hinst): Remove unneeded extern declaration.
676 (_start): Remove initialization of above variables; remove
677 initialization of hinst, as cache_system_info now does that.
679 * emacs.c (main): Call cache_system_info early in startup; we
680 previously weren't calling it in Cygwin builds.

709 Support for filesystem notifications on MS-Windows.
710 * w32proc.c (sys_select): If drain_message_queue returns non-zero,
711 and this is a TTY frame, signal the caller that keyboard input is

819 * w32.c (unsetenv): Return 0 if the input string is too long.
821 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>

932 * callproc.c, process.h (record_kill_process):
933 New function, containing part of the old call_process_kill.
934 (call_process_kill): Use it.
935 This does not change call_process_kill's behavior.
936 * process.c (Fdelete_process): Use record_kill_process to fix a
937 race condition that could cause Emacs to lose track of a child.
939 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
941 Avoid code duplication between prev_frame and next_frame.
942 * frame.c (candidate_frame): New function. Add comment.
943 (prev_frame, next_frame): Use it. Adjust comment.
945 2012-12-06 Eli Zaretskii <eliz@gnu.org>
947 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
948 fails, signal an error instead of continuing with an empty
950 Encode expanded temp file pattern before passing it to mkstemp or
953 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
954 Encode the file name before passing it to dostounix_filename, in
955 case it will downcase it (under w32-downcase-file-names).
958 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
960 Minor call-process cleanups.
961 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
962 at the same time as other platforms, to simplify analysis.
963 No need for fd0_volatile since we have synch_process_fd.
964 Avoid needless emacs_close; arg is always negative.

968 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
971 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>

984 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
986 Don't let call-process be a zombie factory (Bug#12980).
987 Fixing this bug required some cleanup of the signal-handling code.
988 As a side effect, this change also fixes a longstanding rare race
989 condition whereby Emacs could mistakenly kill unrelated processes,
990 and it fixes a bug where a second C-g does not kill a recalcitrant
991 synchronous process in GNU/Linux and similar platforms.
992 The patch should also fix the last vestiges of Bug#9488,
993 a bug which has mostly been fixed on the trunk by other changes.
994 * callproc.c, process.h (synch_process_alive, synch_process_death)
995 (synch_process_termsig, sync_process_retcode):
996 Remove. All uses removed, to simplify analysis and so that
997 less consing is done inside critical sections.
998 * callproc.c (call_process_exited): Remove. All uses replaced
999 with !synch_process_pid.
1000 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
1001 These take the role of what used to be in unwind-protect arg.
1003 (block_child_signal, unblock_child_signal):
1004 New functions, to avoid races that could kill innocent-victim processes.
1005 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
1006 (call_process_kill): Record killed processes as deleted, so that
1007 zombies do not clutter up the system. Do this inside a critical
1008 section, to avoid a race that would allow the clutter.
1009 (call_process_cleanup): Fix code so that the second C-g works again
1010 on common platforms such as GNU/Linux.
1011 (Fcall_process): Create the child process in a critical section,
1012 to fix a race condition. If creating an asynchronous process,
1013 record it as deleted so that zombies do not clutter up the system.
1014 Do unwind-protect for WINDOWSNT too, as that's simpler in the
1015 light of these changes. Omit unnecessary call to emacs_close
1016 before failure, as the unwind-protect code does that.
1017 * callproc.c (call_process_cleanup):
1018 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
1019 * process.c (record_deleted_pid): New function, containing
1020 code refactored out of Fdelete_process.
1021 (Fdelete_process): Use it.
1022 (process_status_retrieved): Remove. All callers changed to use
1023 child_status_change.
1024 (record_child_status_change): Remove, folding its contents into ...
1025 (handle_child_signal): ... this signal handler. Now, this
1026 function is purely a handler for SIGCHLD, and is not called after
1027 a synchronous waitpid returns; the synchronous code is moved to
1028 wait_for_termination. There is no need to worry about reaping
1029 more than one child now.
1030 * sysdep.c (get_child_status, child_status_changed): New functions.
1031 (wait_for_termination): Now takes int * status and bool
1032 interruptible arguments, too. Do not record child status change;
1033 that's now the caller's responsibility. All callers changed.
1034 Reimplement in terms of get_child_status.
1035 (wait_for_termination_1, interruptible_wait_for_termination):
1036 Remove. All callers changed to use wait_for_termination.
1037 * syswait.h: Include <stdbool.h>, for bool.
1038 (record_child_status_change, interruptible_wait_for_termination):
1040 (record_deleted_pid, child_status_changed): New decls.
1041 (wait_for_termination): Adjust to API changes noted above.
1043 * bytecode.c, lisp.h (Qbytecode): Remove.
1044 No longer needed after 2012-11-20 interactive-p changes.
1046 2012-12-03 Eli Zaretskii <eliz@gnu.org>
1048 * xdisp.c (redisplay_window): If the cursor is visible, but inside
1049 the scroll margin, move point outside the margin. (Bug#13055)
1051 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
1053 * gtkutil.c (my_log_handler): New function.
1054 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
1056 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1058 * lisp.h (modify_region): Rename to...
1059 (modify_region_1): ...new prototype.
1060 * textprop.c (modify_region): Now static. Adjust users.
1061 * insdel.c (modify_region): Rename to...
1062 (modify_region_1): ...new function to work with current buffer.
1063 Adjust comment and users. Use true and false for booleans.
1065 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
1067 * alloc.c (free_save_value): New function.
1068 (safe_alloca_unwind): Use it.
1069 * lisp.h (free_save_value): New prototype.
1070 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
1072 (save_excursion_restore): Adjust to match saved data structure.
1073 Use free_save_value to offload some work from GC. Drop obsolete
1076 2012-12-03 Chong Yidong <cyd@gnu.org>
1078 * fileio.c (Vauto_save_list_file_name): Doc fix.
1080 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
1082 * w32fns.c: Remove prototype of atof.
1083 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
1085 (file_dialog_callback): Make it UINT_PTR.
1087 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
1090 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1091 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
1094 2012-12-03 Glenn Morris <rgm@gnu.org>
1096 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
1098 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
1100 Fix xpalloc confusion after memory is exhausted.
1101 * alloc.c (xpalloc): Comment fix.
1102 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1103 and signals an error, do not clear charset_table_size, as
1104 charset_table is still valid.
1105 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1107 Use execve to avoid need to munge environ (Bug#13054).
1108 * callproc.c (Fcall_process):
1109 * process.c (create_process):
1110 Don't save and restore environ; no longer needed.
1111 * callproc.c (child_setup):
1112 Use execve, not execvp, to preserve environ.
1114 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1116 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1118 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1120 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1121 display for sliced images (Bug#10500).
1123 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
1125 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
1127 * doc.c (Fdocumentation): Re-add handling of function-documentation,
1128 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1130 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1132 * xdisp.c (window_outdated): Remove eassert since it hits
1133 some suspicious corner cases (see Bug#13007 and Bug#13012).
1134 (mode_line_update_needed): New function.
1135 (redisplay_internal, redisplay_window): Use it.
1136 (ensure_selected_frame): New function.
1137 (redisplay_internal, unwind_redisplay): Use it.
1138 (redisplay_internal): Move comment about buffer_shared...
1139 (buffer_shared_and_changed): ...near to its real use.
1141 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1143 * callproc.c (Fcall_process): Don't misreport vfork failure.
1145 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1147 * callproc.c (Fcall_process): Fix vfork portability problems.
1148 Do not assume that fd[0], count, filefd, and save_environ survive
1149 vfork. Fix bug whereby wrong errno value could be reported for
1150 pipe failure. Some minor cleanups, too, as follows. Move buf and
1151 bufsize to the context where they're needed. Change new_argv to
1152 be of type char **, as this is more convenient and avoids casts.
1153 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1154 Now local constants, not macros.
1156 2012-11-18 Kenichi Handa <handa@gnu.org>
1158 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1159 for the variable "f".
1161 2012-11-13 Kenichi Handa <handa@gnu.org>
1163 * font.c (font_unparse_xlfd): Exclude special characters from the
1164 generating XLFD name.
1166 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

1179 * lread.c (readbyte_from_file): Assume EINTR is defined.
1180 * process.c (wait_reading_process_output, send_process) [subprocesses]:
1181 Assume EIO and EAGAIN are defined.
1182 * unexcoff.c (write_segment): Assume EFAULT is defined.
1184 2012-11-27 Eli Zaretskii <eliz@gnu.org>

1189 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
1190 highlighting on the frame was cleared. Prevents assertion
1191 violations when repeatedly clicking on the "Top" link of the
1192 "bread-crumbs" in Info buffers.

1206 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1207 between bpos_covered and bpos_max. This fixes cursor display when
1208 several display strings follow each other.
1210 * .gdbinit (pgx): If the glyph's object is a string, display the
1211 pointer to string data, rather than the value of the string object
1212 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1214 * indent.c (Fvertical_motion): If the starting position is covered
1215 by a display string, return to one position before that, to avoid
1216 overshooting it inside move_it_to. (Bug#12930)
1218 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1220 * frame.h (struct frame): Remove display_preempted member

1223 * w32menu.c (pending_menu_activation): Remove since not
1225 (set_frame_menubar): Adjust user.
1226 * w32term.h (struct x_output): Drop outdated #if 0 code.

1229 Drop unused pending_menu_activation member.
1230 * xterm.h (struct x_output): Drop outdated #if 0 code.
1231 Use bitfields for explicit_parent, asked_for_visible,
1232 has_been_visible and net_wm_state_hidden_seen members.
1234 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1236 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1237 of a literal "/". (Bug#12955)
1238 (gl-stamp): Invoke fc.exe directly, not through cmd.
1240 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

1243 * dired.c: Assume HAVE_DIRENT_H.
1244 (NAMLEN): Remove, replacing with ...
1245 (dirent_namelen): New function. All uses changed. Use the GNU macro
1246 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1247 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1248 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1249 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1251 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1252 * ndir.h: Rename to ../nt/inc/dirent.h.
1253 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1254 Do not include <dirent.h>; no longer needed.
1255 * w32.c: Include <dirent.h> rather than "ndir.h".
1257 2012-11-23 Chong Yidong <cyd@gnu.org>
1259 * xftfont.c (xftfont_open): Remove duplicate assignment.
1261 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1263 * alloc.c (Fgarbage_collect): Unblock input after clearing
1264 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1265 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1266 * msdos.c (IT_frame_up_to_date): Use it here...
1267 * w32term.c (w32_frame_up_to_date): ...here...
1268 * xterm.c (XTframe_up_to_date): ...and here...
1269 * nsterm.m (ns_frame_up_to_date): ...but not here.
1270 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1272 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1273 Do not check whether GC is in progress.
1275 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1277 * xdisp.c (window_buffer_changed): New function.
1278 (update_menu_bar, update_tool_bar): Use it to
1279 simplify large 'if' statements.
1280 (redisplay_internal): Generalize commonly used
1281 'tail' and 'frame' local variables.
1283 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1285 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1286 with Windows system header.
1288 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1290 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1291 * alloc.c: Assume unistd.h exists.
1292 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1293 * sysdep.c (get_current_dir_name): Assume getcwd exists.

1295 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1296 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1297 * w32.h (getcwd): Remove decl.
1299 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
1301 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
1302 Make it set selected_window as well.
1303 (update_tool_bar): Use it.
1305 2012-11-21 Ken Brown <kbrown@cornell.edu>
1307 * emacs.c (main): Set the G_SLICE environment variable for all
1308 Cygwin builds, not just GTK builds. See
1309 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1311 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1313 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1314 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1315 Define for the MSVC compiler.
1317 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1319 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1320 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1321 dostounix_filename. Prevents crashes down the road, because
1322 dostounix_filename assumes it gets a unibyte string.
1323 Reported by Michel de Ruiter <michel@sentient.nl>, see
1324 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html

1334 Test NILP rather than Qunbound.
1335 (Ffmakunbound): Set to Qnil.
1336 (Fsymbol_function): Never signal an error.
1337 (Finteractive_form): Ignore Qunbound.
1339 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>

1350 (text_outside_line_unchanged_p, redisplay_window): Use it.
1351 (redisplay_internal): Likewise. Fix indentation.
1353 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1355 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1356 (syms_of_eval): Remove corresponding defsubr.
1357 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1359 2012-11-19 Daniel Colascione <dancol@dancol.org>
1361 * w32fns.c (Fx_file_dialog):
1362 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1363 cygwin_convert_file_name*.
1365 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1366 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1368 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1370 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1372 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1374 * w32select.c: Include w32common.h before w32term.h, so that
1375 windows.h gets included before w32term.h uses some of its
1376 features, see below.
1378 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1380 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
1382 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
1384 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1386 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1387 (ns_select): Return at once if events are held (Bug#12834).
1389 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1391 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1392 Needed following 2012-10-20 change. (Bug#12902)
1394 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1396 * w32proc.c (waitpid): Remove unused label get_result.
1398 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1400 * makefile.w32-in (SYSWAIT_H): New macro.
1401 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1402 ($(BLD)/sysdep.$(O)): Update dependencies.
1404 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1406 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
1407 * callproc.c (relocate_fd): Assume F_DUPFD.
1408 * emacs.c, term.c (O_RDWR): Remove.
1409 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1410 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1411 * nsterm.m: Assume <fcntl.h> exists.
1412 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1413 (create_pty, Fmake_network_process, server_accept_connection)
1414 (wait_reading_process_output, init_process_emacs):
1416 (wait_reading_process_output): Put in a special case for WINDOWSNT
1417 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1418 It's not clear this is needed, but it's a more-conservative change.
1419 (create_process): Assume FD_CLOEXEC.
1420 (create_process, create_pty): Assume O_NOCTTY.
1421 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1422 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1423 Omit if not DOS_NT, since F_GETFL is not defined there.
1424 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1425 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1427 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1428 lack it, since gnulib guarantees this.
1429 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1431 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1433 * w32.c (faccessat): Pretend that directories have the execute bit
1434 set. Emacs expects that, e.g., in files.el:cd-absolute.
1436 * w32proc.c (create_child): Don't clip the PID of the child
1437 process to fit into an Emacs integer, as this is no longer a
1439 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1440 reaping only the process specified by PID argument, if that is
1441 positive. Use PID instead of dead_child to know which process to
1442 reap. Wait for the child to die only if WNOHANG is not in
1444 (sys_select): Don't set dead_child.
1446 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1447 as it is no longer needed.
1449 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1451 (record_child_status_change): Remove the setting of
1452 record_at_most_one_child for the !WNOHANG case.
1454 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1456 Fix problems in ns port found by static checking.
1457 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1458 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1459 not to process group.
1460 (ns_select): Use emacs_write, not write, as that's more robust
1461 in the presence of signals.
1462 (fd_handler:): Check for read errors.
1464 2012-11-16 Glenn Morris <rgm@gnu.org>
1466 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1468 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1470 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1472 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1474 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1475 use the same value of thread handle.
1476 (start_timer_thread): If the timer thread exited (due to error),
1477 clean up by closing the two handles it used. Duplicate the caller
1478 thread's handle here, so it gets duplicated only once, when
1479 launching the timer thread. Set priority of the timer thread, not
1481 (getitimer): Don't duplicate the caller thread's handle here.
1484 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1486 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1489 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1491 Remove no-longer-used pty_max_bytes variable.
1492 * process.c (pty_max_bytes): Remove; unused.
1493 (send_process): Do not set it.
1495 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1497 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1498 Update dependencies.
1500 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1502 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1503 This follows up on the 2012-09-29 patch that removed indirection
1504 for the 'function' field. Reported by Sergey Vinokurov in
1505 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1507 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1509 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1510 different name, as the MS runtime does not have such a function,
1511 and probably never will.) All callers changed. Ignore DIRFD
1512 value if PATH is an absolute file name, to match Posix spec
1513 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1516 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1518 * xdisp.c (echo_area_display, redisplay_internal):
1519 Omit redundant check whether frame_garbaged is set.
1521 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1523 Use faccessat, not access, when checking file permissions (Bug#12632).
1524 This fixes a bug that has been present in Emacs since its creation.
1525 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1526 which must set some sort of record. (Torek's bug report was against
1527 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1528 same common flaw.) See Torek's Usenet posting
1529 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1530 Posted: Fri Apr 8 14:18:56 1983.
1531 * Makefile.in (LIB_EACCESS): New macro.
1533 * callproc.c (init_callproc):
1534 * charset.c (init_charset):
1535 * fileio.c (check_existing, check_executable, check_writable)
1537 * lread.c (openp, load_path_check):
1538 * process.c (allocate_pty):
1540 Use effective UID when checking permissions, not real UID.
1541 * callproc.c (init_callproc):
1542 * charset.c (init_charset):
1543 * lread.c (load_path_check, init_lread):
1544 Test whether directories are accessible, not merely whether they exist.
1545 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1546 * fileio.c (check_existing, check_executable, check_writable)
1548 Use symbolic names instead of integers for the flags, as they're
1550 (check_writable): New arg AMODE. All uses changed.
1551 Set errno on failure.
1552 (Ffile_readable_p): Use faccessat, not stat + open + close.
1553 (Ffile_writable_p): No need to call check_existing + check_writable.
1554 Just call check_writable and then look at errno. This saves a syscall.
1555 dir should never be nil; replace an unnecessary runtime check
1556 with an eassert. When checking the parent directory of a nonexistent
1557 file, check that the directory is searchable as well as writable, as
1558 we can't create files in unsearchable directories.
1559 (file_directory_p): New function, which uses 'stat' on most platforms
1560 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1561 (Ffile_directory_p, Fset_file_times): Use it.
1562 (file_accessible_directory_p): New function, which uses a single
1563 syscall for efficiency.
1564 (Ffile_accessible_directory_p): Use it.
1565 * xrdb.c (file_p): Use file_directory_p.
1566 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1567 * lread.c (openp): When opening a file, use fstat rather than
1568 stat, as that avoids a permissions race. When not opening a file,
1569 use file_directory_p rather than stat.
1570 (dir_warning): First arg is now a usage string, not a format.
1571 Use errno. All uses changed.
1572 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1573 that merely introduced a race.
1574 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1575 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1576 and similarly for the other O_* flags.
1577 * w32.c (sys_faccessat): Rename from sys_access and switch to
1578 faccessat's API. All uses changed.
1579 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1580 (magic_db): Rename from magic_file_p.
1581 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1582 char *, so that we don't have to test for file existence
1583 separately from opening the file for reading. This removes a race
1584 fixes a permission-checking problem, and simplifies the code.
1586 (file_p): Remove; no longer needed.
1588 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1590 Omit glyphs initialization at startup.
1591 * dispnew.c (glyphs_initialized_initially_p): Remove.
1592 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1593 (Fredraw_frame): Move actual code from here...
1594 (redraw_frame): ...to here. Add eassert. Adjust comment.
1595 (Fredraw_display): Use redraw_frame.
1596 * xdisp.c (clear_garbaged_frames): Likewise.
1598 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1600 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1601 passed to pint2str and pint2hrstr to be at most the size of the
1602 frame's decode_mode_spec_buffer. This avoids crashes with very
1603 large values of FIELD_WIDTH argument to decode_mode_spec.
1606 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1608 Fix a race with verify-visited-file-modtime (Bug#12863).
1609 Since at least 1991 Emacs has ignored an mtime difference of no
1610 more than one second, but my guess is that this was to work around
1611 file system bugs that were fixed long ago. Since the race is
1612 causing problems now, let's remove that code.
1613 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1614 whose time stamp is off by no more than a second. Insist that the
1615 file time stamps match exactly.
1617 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1619 * frame.h (struct frame): Convert external_tool_bar member to
1620 1-bit unsigned bitfield.
1621 * termhooks.h (struct terminal): Remove mouse_moved member since
1622 all users are long dead. Adjust comment on mouse_position_hook.
1624 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1626 Simplify by using FOR_EACH_FRAME here and there.
1627 * frame.c (next_frame, prev_frame, other_visible_frames)
1628 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1629 * w32term.c (x_window_to_scroll_bar): Likewise.
1630 * window.c (window_list): Likewise.
1631 * xdisp.c (x_consider_frame_title): Likewise.
1632 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1633 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1634 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1635 * xmenu.c (menubar_id_to_frame): Likewise.
1636 * xselect.c (frame_for_x_selection): Likewise.
1637 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1638 (x_window_to_menu_bar): Likewise.
1639 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1641 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1643 * data.c (Qdefalias_fset_function): Now static.
1645 Another tweak to vectorlike_header change.
1646 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
1647 Remove, and replace all uses with ...
1648 (next_in_free_list, set_next_in_free_list):
1649 New functions, which respect C's aliasing rules better.
1651 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1653 * window.c (list4i): Rename from 'quad'. All uses changed.
1654 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1656 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1658 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1659 warning about mixing declarations and code in ISO C90.
1661 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1663 * window.c (Fsplit_window_internal): Set combination limit of
1664 new parent window to t iff Vwindow_combination_limit is t;
1665 fixing a regression introduced with the change from 2012-09-22.
1666 (Fset_window_combination_limit): Fix doc-string.
1668 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1670 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1671 amount when the scroll margins are too large. When scrolling
1672 backwards in the buffer, give up if cannot reach point or the
1673 scroll margin within a reasonable number of screen lines.
1674 Fixes point position in window under scroll-up/down-aggressively when
1675 point is positioned many lines beyond the window top/bottom.
1678 * ralloc.c (relinquish): If real_morecore fails to return memory
1679 to the system, don't crash; instead, leave the last heap
1680 unchanged and return. (Bug#12774)
1682 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1684 * lisp.h (AUTOLOADP): New macro.
1685 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
1686 * data.c (Ffset): Remove special ad-advice-info handling.
1687 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1689 (Finteractive_form): Simplify.
1690 (Fquo): Don't insist on having at least 2 arguments.
1691 (Qdefalias_fset_function): New var.
1693 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1695 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
1697 * nsfont.m (Qcondensed, Qexpanded): New variables.
1698 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
1699 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
1701 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1703 Fix recently introduced crash on MS-Windows (Bug#12839).
1704 * w32term.h (struct scroll_bar): Use convenient header.
1705 (SCROLL_BAR_VEC_SIZE): Remove.
1706 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1708 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1710 Tweak last vectorlike_header change.
1711 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1712 vectorlike object on the free list. This is introduced to avoid
1713 some (but not all) pointer casting and aliasing problems, see
1714 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1715 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
1717 (xvectype, xvecsize): Use them to examine Lisp_Object values.
1719 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1721 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1722 been removed, so remove them here also.
1724 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1726 * doc.c (Fdocumentation): Handle new property
1727 dynamic-docstring-function to replace the old ad-advice-info.
1729 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
1731 * fns.c (Qeql, hashtest_eq): Now static.
1733 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1735 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1736 * fns.c (hashfn_eq, hashfn_eql, sxhash):
1737 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
1738 * buffer.c (compare_overlays): Use XLI rather than XHASH.
1740 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
1742 Use same hash function for hashfn_profiler as for hash_string etc.
1743 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
1744 * lisp.h (sxhash_combine): New inline function, with the contents
1745 of the old SXHASH_COMBINE.
1746 * profiler.c (hashfn_profiler): Use it, instead of having a
1747 special hash function containing a comparison that always yields 1.
1749 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1751 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1752 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1753 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1756 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1758 * image.c (xpm_make_color_table_h): Fix compiler error because
1759 make_hash_table changed.
1761 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
1763 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
1765 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1767 Use ad-hoc comparison function for the profiler's hash-tables.
1768 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1769 (make_log): Use them.
1770 (handle_profiler_signal): Don't inhibit quit any longer since we don't
1771 call Fequal any more.
1772 (Ffunction_equal): New function.
1773 (cmpfn_profiler, hashfn_profiler): New functions.
1774 (syms_of_profiler): Initialize them.
1775 * lisp.h (struct hash_table_test): New struct.

1780 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
1781 (hash_lookup, hash_remove_from_table): Move assertion checking of
1782 hashfn result here. Check hash-equality before calling cmpfn.

1789 * print.c (print_object): Adjust to new hash-table struct.
1790 * composite.c (composition_gstring_put_cache): Adjust to new hashfn.
1792 2012-11-08 Eli Zaretskii <eliz@gnu.org>
1794 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
1795 value of w32-scroll-lock-modifier is neither nil nor one of the
1796 known key modifiers. (Bug#12806)
1798 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1800 Shrink struct vectorlike_header to the only size field.
1801 * lisp.h (enum pvec_type): Avoid explicit enum member values.
1803 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
1804 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
1805 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
1806 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
1807 information from the vector header. Adjust comment.
1808 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
1809 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
1811 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
1812 (struct vectorlike_header): Remove next member. Adjust comment.

1815 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
1816 (sweep_string, lisp_malloc): Remove useless prototypes.
1817 (enum mem_type): Adjust comment.
1818 (NEXT_IN_FREE_LIST): New macro.
1819 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
1820 (Fmake_bool_vector): Likewise.
1821 (struct large_vector): New type to represent allocation unit for
1822 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1823 (large_vectors): Change type to struct large_vector.
1824 (allocate_vector_from_block): Simplify.
1825 (PSEUDOVECTOR_NBYTES): Replace with...
1826 (vector_nbytes): ...new function. Adjust users.
1827 (sweep_vectors): Adjust processing of large vectors.
1828 (allocate_vectorlike): Likewise.
1829 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
1830 Add easserts. Adjust XSETPVECTYPESIZE usage.
1831 (allocate_buffer): Use BUFFER_PVEC_INIT.
1832 (live_vector_p): Adjust to match large vector.
1833 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
1834 * buffer.h (struct buffer): Add next member.
1835 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
1837 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
1838 * fns.c (internal_equal): Adjust to match enum pvec_type change.
1839 (copy_hash_table): Adjust to match vector header change.
1840 * lread.c (defsubr): Use XSETPVECTYPE.
1841 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
1842 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
1843 (xvecsize): New command.
1845 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
1847 * keyboard.c (event_to_kboard): Do not dereference
1848 frame_or_window field of SELECTION_REQUEST_EVENT
1849 and SELECTION_CLEAR_EVENT events (Bug#12814).
1850 * xterm.h (struct selection_input_event): Adjust comment.
1852 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1854 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1855 such as Scroll Lock, if the respective keys are treated as
1856 function keys, not as modifiers. This avoids destroying non-ASCII
1857 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
1859 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
1861 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
1863 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1865 Restore some duplicate definitions (Bug#12814).
1866 This undoes part of the 2012-11-03 changes. Some people build
1867 with plain -g rather than with -g3, and they need the duplicate
1868 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1869 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1870 Define as macros, as well as as enums or as constants.
1872 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
1874 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
1875 to keypad keys (Bug#12816).
1877 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1879 Minor adjustments of recently-changed frame functions.
1880 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1881 known to be a frame (we're in the FRAMEP branch).
1882 * lisp.h (Qframep): Remove decl. frame.h declares this.
1883 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1884 since they're meant for Lisp fixnum values.
1886 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1888 * window.c (Fwindow_combination_limit): Revert to the only
1889 required argument and adjust docstring as suggested in
1890 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html

1911 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
1912 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
1913 (Fclose_font, Ffont_info): Use decode_live_frame.

1938 (Fwindow_combination_limit): Allow zero number of arguments.
1940 2012-11-05 Eli Zaretskii <eliz@gnu.org>
1942 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
1944 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
1945 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
1946 file descriptor 2 for standard error. (Bug#12805)
1948 2012-11-05 Chong Yidong <cyd@gnu.org>
1950 * process.c (wait_reading_process_output): Revert previous change.
1952 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1954 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
1955 This removes code that has been obsolete since around 1990.
1956 * callproc.c (Fcall_process):
1958 * process.c (create_process):
1959 * term.c (dissociate_if_controlling_tty):
1960 Assume setsid exists.
1961 * callproc.c (child_setup): Assume setpgid exists and behaves as
1962 per POSIX.1-1988 or later.
1963 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1964 * emacs.c (shut_down_emacs):
1965 * sysdep.c (sys_suspend, init_foreground_group):
1966 Assume getpgrp behaves as per POSIX.1-1998 or later.
1967 * msdos.c (setpgrp): Remove.
1968 (tcgetpgrp, setpgid, setsid): New functions.
1969 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1970 * term.c (no_controlling_tty): Remove; unused.
1971 * w32proc.c (setpgrp): Remove.
1972 (setsid, tcgetpgrp): New functions.
1974 Simplify by assuming __fpending.
1975 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1976 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1977 Do not assume that __fpending's result fits in int.
1979 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1981 Remove EMACS_OUTQSIZE+sleep hack.
1982 * dispnew.c (update_frame_1): Remove hack for terminals slower
1983 than 2400 bps, which throttled Emacs by having it sleep.
1984 This code hasn't worked since at least 2007, when the multi-tty stuff
1985 was added, and anyway those old terminals are long dead.
1986 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1987 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1989 Fix data-loss with --version (Bug#9574).
1990 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1991 as we can't assume that emacs_strerror is initialized, and strerror
1992 is good enough here.
1993 (main): Invoke atexit earlier, to catch earlier instances of
1994 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1996 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1998 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1999 (keyDown): Remap keypad keys to X11 virtual key codes.
2001 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
2003 Fix data-loss with --batch (Bug#9574).
2004 * emacs.c: Include <close-stream.h>.
2005 (close_output_streams): New function.
2006 (main): Pass it to atexit, so that Emacs closes stdout and stderr
2007 and handles errors appropriately.
2008 (Fkill_emacs): Don't worry about flushing, as close_output_stream
2011 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
2012 The symptom is a diagnostic "GLib-WARNING **: In call to
2013 g_spawn_sync(), exit status of a child process was requested but
2014 SIGCHLD action was set to SIG_IGN and ECHILD was received by
2015 waitpid(), so exit status can't be returned." The diagnostic
2016 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
2017 The real bug is a race condition between Emacs and glib: Emacs
2018 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
2019 so that glib can't find it. Work around the bug by invoking
2020 waitpid only on subprocesses that Emacs itself creates.
2021 * process.c (create_process, record_child_status_change):
2022 Don't use special value -1 in pid field, as the caller now must
2023 know the pid rather than having the callee infer it.
2024 The inference was sometimes incorrect anyway, due to another race.
2025 (create_process): Set new 'alive' member if child is created.
2026 (process_status_retrieved): New function.
2027 (record_child_status_change): Use it.
2028 Accept negative 1st argument, which means to wait for the
2029 processes that Emacs already knows about. Move special-case code
2030 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
2031 processes that have already been waited for, by testing and
2032 clearing new 'alive' member.
2033 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
2034 now does this internally.
2035 (handle_child_signal): Let record_child_status_change do all
2036 the work, since we do not want to reap all exited child processes,
2037 only the child processes that Emacs itself created.
2038 * process.h (Lisp_Process): New boolean member 'alive'.
2040 Omit duplicate definitions no longer needed with gcc -g3.
2041 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
2042 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
2043 Define only as macros. There's no longer any need to also define
2044 these symbols as enums or as constants, since we now assume
2045 gcc -g3 when debugging.
2047 2012-11-03 Eli Zaretskii <eliz@gnu.org>
2049 * lisp.mk: Adjust comments to the fact that term/internal is now
2050 loaded from loadup.el.
2052 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
2053 (msdos_fatal_signal): New function.
2054 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
2057 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
2058 for GCC versions before 4.
2059 (emacs_raise): Define to call msdos_fatal_signal.
2061 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
2062 iterator when starting in the middle of a display or overlay
2065 2012-11-03 Chong Yidong <cyd@gnu.org>
2067 * process.c (wait_reading_process_output): Clean up the last
2070 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
2072 * process.c (wait_reading_process_output): Avoid a race condition
2073 with SIGIO delivery (Bug#11536).
2075 2012-11-03 Chong Yidong <cyd@gnu.org>
2077 * buffer.c (cursor_type): Untabify docstring.
2079 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2081 * frame.h (struct frame): Drop can_have_scroll_bars member
2082 which is meaningless for a long time. Adjust comments.
2083 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2084 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2086 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2088 * window.c (decode_next_window_args): Update window arg after
2089 calling decode_live_window and so fix crash reported at
2090 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2091 by Juanma Barranquero <lekktu@gmail.com>.
2092 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2093 * font.c (Ffont_at): Likewise.
2095 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2097 * widget.c (resize_cb): New function.
2098 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2099 (EmacsFrameResize): Check if all is up to date before changing frame
2102 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2104 Implement backtrace output for fatal errors on MS-Windows.
2105 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2106 (BACKTRACE_LIMIT_MAX): New macro.
2107 (w32_backtrace): New function.
2108 (emacs_abort): Use w32_backtrace when the user chooses not to
2109 attach a debugger. Update the text of the abort dialog.
2111 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2113 Window-related stuff cleanup here and there.
2114 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2115 Use decode_any_window.
2116 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2117 * xdisp.c (Fformat_mode_line): Likewise.
2118 * font.c (Ffont_at): Use decode_live_window.
2119 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2120 * window.c (decode_next_window_args): Likewise.
2121 (decode_any_window): Remove static.
2122 * window.h (decode_any_window): Add prototype.
2123 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2124 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2127 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2129 Remove pad from struct input_event.
2130 * termhooks.h (struct input_event): Remove padding field.
2132 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2133 member is never cons for a long time. Adjust comment.
2134 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2135 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2136 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2137 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2139 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2141 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2143 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2145 Fix crash when using Emacs as commit editor for git (Bug#12697).
2146 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2147 and it is configured in conf_post.h.
2148 (Fcall_process): Don't invoke both setsid and setpgid; the former
2149 is enough, if it exists.
2150 * callproc.c (Fcall_process, child_setup):
2151 * process.c (create_process): Use setpgid.
2152 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2154 * dispnew.c (init_display): Initialize the foreground group
2155 if we are running a tty display.
2156 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2157 * lisp.h (init_foreground_group): New decl.
2158 * sysdep.c (inherited_pgroup): New static var.
2159 (init_foreground_group, tcsetpgrp_without_stopping)
2160 (narrow_foreground_group, widen_foreground_group): New functions.
2161 (init_sys_modes): Narrow foreground group.
2162 (reset_sys_modes): Widen foreground group.
2164 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2166 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2168 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2170 * minibuf.c (read_minibuf): Restore current buffer since
2171 choose_minibuf_frame calling Fset_frame_selected_window may
2172 change it (Bug#12766).
2174 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2176 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2178 2012-10-30 Kenichi Handa <handa@gnu.org>
2180 * font.c (Ffont_at): If WINDOW is specified and it is not
2181 displaying the current buffer, signal an error.
2183 2012-10-29 Daniel Colascione <dancol@dancol.org>
2185 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2186 In preparation for fixing bug#12739, move these functions from
2189 * coding.h, coding.c: ... to here, and compile them only when
2190 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2191 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2193 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2195 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2196 (timer_loop, getitimer, setitimer): Use it instead of
2197 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2199 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2202 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2204 * nsterm.m (NO_APPDEFINED_DATA): New define.
2205 (last_appdefined_event_data): New variable
2206 (last_appdefined_event): Remove.
2207 (ns_select): Initialize t from last_appdefined_event_data instead
2208 of [last_appdefined_event data1].
2209 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2210 remove last_appdefined_event (Bug#12698).
2212 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2214 * frame.c (x_set_font): Catch internal error.
2216 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2218 Avoid overflow in w32 implementation of interval timers.
2219 When possible, for ITIMER_PROF count only times the main thread
2221 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2222 'volatile ULONGLONG' types. All the other data which was
2223 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2224 (GetThreadTimes_Proc): New typedef.
2225 (w32_get_timer_time): New function, returns a suitable time value
2227 (timer_loop): Enter critical section when accessing ULONGLONG
2228 values of the itimer_data struct, as these accesses are no longer
2229 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2230 Remove unused variable.
2231 (init_timers): Initialize s_pfn_Get_Thread_Times.
2232 (start_timer_thread): Don't assign itimer->caller_thread here.
2233 (getitimer): Assign itimer->caller_thread here.
2234 (setitimer): Always call getitimer to get the value of ticks_now.
2235 (sys_spawnve): Avoid compiler warning about format mismatch.
2237 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2239 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2240 mouse movement events if the menu bar is active. This avoids
2241 producing a busy "hour-glass" cursor by Windows if the mouse
2242 pointer is positioned over a tooltip shown for some menu item.
2244 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2246 Don't assume process IDs fit in int.
2247 * emacs.c (shut_down_emacs) [!DOS_NT]:
2248 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2249 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2250 Use pid_t, not int, to store process IDs, as 'int'
2251 is not wide enough on a few platforms (e.g., AIX and IRIX).
2253 2012-10-23 Kenichi Handa <handa@gnu.org>
2255 The following change is to make face-font-rescale-alist work
2256 correctly for non-ASCII fonts.
2258 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2259 (font_open_for_lface): Handle Vface_font_rescale_alist.
2261 2012-10-23 Chong Yidong <cyd@gnu.org>
2263 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2265 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
2267 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
2269 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2271 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2274 2012-10-21 Glenn Morris <rgm@gnu.org>
2276 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2278 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2280 Port to OpenBSD 5.1.
2281 * frame.c (Fmouse_position, Fmouse_pixel_position):
2282 * xdisp.c (produce_stretch_glyph):
2283 Declare local vars only when they're needed.
2284 This is clearer and avoids a warning on OpenBSD about unused vars.
2285 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2286 This is safer, and avoids OpenBSD warnings about unused vars.
2287 * keyboard.c (record_menu_key): Remove unnecessary decl.
2288 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2289 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2290 as our definition clashes with OpenBSD's.
2291 * xfaces.c (load_face_colors, check_lface_attrs)
2292 (get_lface_attributes_no_remap, get_lface_attributes)
2293 (lface_fully_specified_p, x_supports_face_attributes_p)
2294 (tty_supports_face_attributes_p, face_fontset, realize_face)
2295 (realize_x_face, realize_tty_face):
2296 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2297 merely Lisp_Object *. This is more informative and avoids
2298 a warning on OpenBSD about accessing beyond an object's size.
2300 2012-10-20 Chong Yidong <cyd@gnu.org>
2302 * lread.c (Fload): Doc fix (Bug#12592).
2304 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2306 * font.c (Ffont_at): Fix previous change.
2308 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2310 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2311 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
2314 * alloc.c (NSTATICS): Decrease to 0x800.
2316 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>
2318 * fns.c (Fnreverse): Include the problem element when signaling an
2321 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
2323 * nsterm.m (ns_select): Check writefds before call to
2324 FD_ISSET (Bug#12668).
2326 2012-10-18 Daniel Colascione <dancol@dancol.org>
2328 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2329 (staticpro): If we run out of staticpro slots, die with an
2330 informative error instead of just calling emacs_abort.
2332 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2334 Fix two flaws reported by Dmitry Antipov.
2335 * window.c (Ftemp_output_buffer_show): Remove.
2336 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
2337 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
2339 2012-10-17 Eli Zaretskii <eliz@gnu.org>
2341 * makefile.w32-in ($(BLD)/w32.$(O)):
2342 ($(BLD)/vm-limit.$(O)):
2344 ($(BLD)/unexw32.$(O)):

2591 (get_input_pending): Remove first argument, since it was always
2592 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2593 and behave as if it had that value. Return new value of
2594 input_pending. All callers changed.
2595 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2596 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

2639 match what GetLastError returns. Explain why the function is
2642 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2643 'is_tooltip_frame', to avoid confusion with its global namesake.
2645 2012-10-08 Daniel Colascione <dancol@dancol.org>
2647 * xdisp.c (start_hourglass): Call w32_note_current_window when
2648 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2649 build that caused Emacs to display the hourglass cursor forever.
2651 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2652 which is broken under remote desktop, calculate the number of
2653 colors available for a display based on the display's number of
2654 planes and number of bits per pixel per plane. (bug#10397).
2656 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2658 * nsfont.m (Vfonts_in_cache): New variable.
2659 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2660 are used. Add cached fonts to Vfonts_in_cache.
2661 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2663 2012-10-08 Juanma Barranquero <lekktu@gmail.com>

2691 2012-10-08 Daniel Colascione <dancol@dancol.org>
2693 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2694 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2695 accidental message numbering hole. Change other messages to

2718 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2719 Use `report_file_error' instead of `error' in order to better
2720 inform users of what went wrong. Increase NTGUI_UNICODE file
2721 dialog box file name length to 32k, the maximum allowed by the NT
2724 * w32common.h: New file.
2725 (ROUND_UP, ROUND_DOWN, get_page_size)

2729 (OS_NT, os_subtype, cache_system_info): Move here.
2731 * unexw32.c, unexcw.c: Include w32common.h.
2733 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2734 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2735 to call syms_of_w32select.
2737 * cygw32.h: Remove obsolete EXFUN declarations.
2739 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.

2751 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2753 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2756 2012-10-08 Daniel Colascione <dancol@dancol.org>
2758 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2759 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2760 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,

2763 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2764 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2765 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2766 now a supported configuration.
2768 * Makefile.in: consolidate image variables into LIBIMAGE; add
2769 W32_OBJ and W32_LIBS. Compile new files.
2772 (_DebPrint) declare tracing facility for W32 debugging. We need
2773 to unify tracing later.
2775 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2776 unconditional use of W32 Unicode functions. Cygwin runs only on
2777 100% Unicode operating systems.
2779 * cygw32.c: New file. Define Cygwin-specific facilities.
2780 (Fcygwin_convert_path_to_windows)
2781 (Fcygwin_convert_path_from_windows): New user functions for
2782 accessing Cygwin path-munging routines.
2784 * cygw32.h: New file.
2785 (WCSDATA, to_unicode, from_unicode): Define facilities for storing

2789 (w32_strerror): Just what it says on the tin.
2791 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2792 also run for Cygwin; both systems have the same problem with using
2793 GUI facilities in a forked child. Also call syms_of_cygw32,
2794 syms_of_w32select in correct places.
2796 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2797 needs fork-then-exec for daemon launching.
2799 * font.h: Include frame.h.
2801 * image.c: Use the image library cache machinery only when we're
2802 compiling for native WINDOWSNT; Cygwin can use shared libraries
2803 like any other Unixlike system.
2805 * keyboard.c: Clarify a comment regarding the input loop.
2807 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2808 functions directly instead of trying to detect at runtime that our
2809 host operating system supports them. We make this change for two
2810 reasons: Cygwin lacks support for the multibyte character
2811 conversion functions used by the legacy menu code, and Cygwin
2812 never needs to rely on non-Unicode APIs.
2814 * unexw32.c (hinst): Declare extern.
2816 * w32.c: Change header order;
2817 (w32_strerror): Move to w32fns.c because we need it for
2818 non-WINDOWSNT builds.
2820 * w32.h: Add #error macro to make sure we don't include w32.h for
2821 Cygwin builds. Remove w32select declarations.
2823 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2824 w32fns.c. w32console.c is WINDOWSNT-only.
2826 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2827 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2829 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2830 (w32_major_version, w32_minor_version, w32_build_number)
2831 (os_subtype, sound_type): Define here
2832 (w32_defined_color): Make color parameter const for consistency
2833 with other _defined_color functions.
2834 (w32_createwindow): Unconditionally call w32_init_class instead of
2835 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2836 through the code is complex and unnecessary because class
2837 registration is practically free.
2838 (w32_name_of_message): New EMACSDEBUG-only function.
2839 (Fset_message_beep): Move here
2840 (Fx_open_connection): Require that the display name for Windows be
2841 "w32" for consistency, emacsclient disambiguation, and maybe, one
2842 day, multi-window-system support.
2843 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2844 Cygwin files for W32 GUI facilities, since these clearly don't
2845 expect Cygwin names.
2846 (_DebPrint): Define.
2847 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2848 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2849 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2850 (w32_last_error): Remove.
2852 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2854 * w32heap.c (syspage_mask): Declare here.
2855 (cache_system_info): Remove.
2857 * w32inevt.c (faked_key): Define globally, not statically.
2858 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2859 (w32_console_toggle_lock_key): Move to w32fns.c.
2861 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2863 * w32proc.c (_DebPrint): Move to w32fns.c.
2864 * w32select.c: Include string.h, stdio.h for Cygwin.
2865 * w32select.h: New File.
2867 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2869 (w32_message_fd): New variable. Under Cygwin, holds the file
2870 descriptor the system used to tell us about pending thread
2873 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2874 that prevented compilation under non-WINDOWSNT systems.
2876 (w32_initialize): Open /dev/windows and assign it to
2877 w32_message_fd. Provide w32 feature.
2879 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2880 (WM_EMACS_INPUT_READY): add.
2881 (prepend_msg, w32_message_fd): Declare globally.
2884 (keyboard_handle): Use only when WINDOWSNT.
2885 (notify_msg_ready): New function. Posts a message to the main
2886 thread's message queue under CYGWIN, which wakes up the main
2887 thread from select(2) by making the /dev/windows file descriptor
2888 ready. Under WINDOWSNT, it sets an event the same way the old
2891 (post, prepend_msg): Actually call notify_msg_ready instead of
2892 setting the input event directly.
2894 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2896 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2897 but it still has blocs in it, don't return it to the system,
2898 instead of aborting. (Bug#12402)
2900 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2902 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2904 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
2905 MAC_OS_X_VERSION_10_6.
2906 (syms_of_nsterm): Remove comment about Panther and above for
2908 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.

2910 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
2912 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
2913 MAC_OS_X_VERSION_10_4.
2915 * nsmenu.m (fillWithWidgetValue:): Remove code for <
2916 MAC_OS_X_VERSION_10_2.
2918 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
2920 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
2921 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
2923 * nsterm.m (ns_in_resize): Remove (Bug#12479).
2924 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
2925 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
2926 Remove ns_in_resize check.

2929 * nsfns.m (ns_in_resize): Remove.
2930 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
2931 Remove ns_in_resize check.
2933 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2935 Improve sys_siglist detection.
2936 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2937 defined as a macro, as is done in Solaris.
2938 (sys_siglist_entries): New macro.
2939 (save_strsignal): Use it.
2940 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2941 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2943 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2945 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2946 fullscreen/Fullscreen.
2948 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2949 tobar_height is new.
2951 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2952 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2953 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
2954 (windowDidResize:): Check for correct window if old style fullscreen.
2955 Capitalize word in comment. Remove incorrect comment.
2956 (initFrameFromEmacs:): tbar_height renamed tibar_height.
2957 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
2958 error in drawing background.
2959 (toggleFullScreen:): Remove comment. Rearrange calls.
2960 Set toolbar values to zero, save old height in tobar_height.
2961 Restore tool bar height when leaving fullscreen.
2962 (canBecomeMainWindow): New function.
2964 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
2966 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2968 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2970 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2972 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2973 that time stamps of directories could also be changed.
2974 Don't request the too broad GENERIC_WRITE, only the more restrictive
2975 FILE_WRITE_ATTRIBUTES access rights.
2977 * fileio.c (Fset_file_times): Special-case ignoring errors for
2978 directories only on MSDOS, not on MS-Windows.
2980 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2982 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2984 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2986 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2987 see whether CreateFile failed.
2989 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2991 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2992 to avoid similar races.
2993 * keyboard.c (pending_signals): Now bool, not int.
2995 Port timers to OpenBSD, plus check for timer failures.
2996 OpenBSD problem reported by Han Boetes.
2997 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2999 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
3000 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
3001 like OpenBSD, which has timer_settime but does not declare it.
3002 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
3003 whether to use itimerspec-related primitives. All uses of
3004 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
3006 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3008 * profiler.c (handle_profiler_signal): Fix a malloc race
3009 that caused Emacs to hang on Fedora 17 when profiling Lisp.
3011 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
3013 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
3015 2012-10-02 Eli Zaretskii <eliz@gnu.org>
3017 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
3018 consistent with the change in return value of 'safe_strsignal'.
3020 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
3022 Prefer plain 'static' to 'static inline' (Bug#12541).
3023 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
3024 (bidi_set_sor_type, bidi_push_embedding_level)
3025 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
3026 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)

3030 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3031 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
3032 Now 'static', not 'static inline'.
3034 Count overruns when profiling; change units to ns.
3035 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
3036 Give extra weight to samples after overruns, to attempt to count
3037 the time more accurately.
3038 (setup_cpu_timer): Change sampling interval units from ms to ns, since
3039 the underlying primitives nominally do ns.
3040 (Fprofiler_cpu_start): Document the change. Mention that
3041 the sampling intervals are only approximate.
3043 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3045 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
3047 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
3048 case for the special 0 coding-system.
3050 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
3051 (Fmake_overlay): Remove redundant tests.
3052 (fix_start_end_in_overlays): Remove redundant recentering.
3054 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
3056 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
3057 Update dependencies.
3059 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3061 Fix a malloc race condition involving strsignal.
3062 A signal can arrive in the middle of a malloc, and Emacs's signal
3063 handler can invoke strsignal, which can invoke malloc, which is
3064 not portable. This race condition bug makes Emacs hang on GNU/Linux.
3065 Fix it by altering the signal handler so that it does not invoke
3067 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
3068 * process.c (status_message): Use const pointer, in case strsignal
3069 is #defined to safe_strsignal.
3070 * sysdep.c (sys_siglist, init_signals): Always define and
3071 initialize a substitute sys_siglist if the system does not define
3072 one, even if HAVE_STRSIGNAL.
3073 (safe_strsignal): Rename from strsignal. Always define,
3074 using sys_siglist. Return a const pointer.
3075 * syssignal.h (safe_strsignal): New decl.
3076 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3078 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3080 * w32proc.c (timer_loop): Fix code that waits for timer
3081 expiration, to avoid high CPU usage.
3083 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3085 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3086 (sweep_weak_table): Remove redundant prototypes.
3088 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3090 * emacs.c: Move the inclusion of TERM_HEADER after including
3091 windows.h on WINDOWSNT. This avoids compilation problems with
3094 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3096 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3097 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3098 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3099 as the previous version used 'void *'.
3101 * ralloc.c (ROUNDUP): Fix last change.
3102 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3105 * w32proc.c <disable_itimers>: New static flag.
3106 (init_timers): Initialize it to zero, after creating the critical
3107 sections used by the timer threads.
3108 (term_timers): Set to 1 before deleting the critical sections.
3109 (getitimer, setitimer): If disable_itimers is non-zero, return an
3110 error indication without doing anything. Reported by Fabrice
3111 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3112 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3114 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3117 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3118 term_ntproc after all the other bookkeeping, to get timers working
3119 as long as possible.
3121 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3123 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3124 Suggested by Juri Linkov in
3125 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3127 Prefer plain 'static' to 'static inline' (Bug#12541).
3128 With static functions, modern compilers inline pretty well by
3129 themselves; advice from programmers often hurts as much as it helps.
3130 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3131 this change shrinks the text size of the Emacs executable by 1.1%
3132 without affecting CPU significantly in my benchmark.
3133 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
3134 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

3208 (x_set_glyph_string_clipping, x_clear_glyph_string_rect):
3209 Now 'static', not 'static inline'.
3212 (bidi_copy_it): Do the whole copy with a single memcpy.
3213 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3215 Revert the FOLLOW-SYMLINKS change for file-attributes.
3216 Doing it right would require several changes to Tramp, and there's
3217 not enough time to get that tested before the freeze today.
3218 * dired.c (directory_files_internal, Ffile_attributes):
3221 * frame.c (x_report_frame_params): Port better to wider ints.
3222 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3223 or that pointers can be printed in 15 decimal digits.
3224 Avoid GCC warnings if EMACS_UINT is wider than a pointer.
3226 2012-09-30 Fabrice Popineau <fabrice.popineau@supelec.fr>

3255 * w32.c (init_environment, get_emacs_configuration): Support AMD64
3257 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
3258 compatibility with x64.
3260 * vm-limit.c (lim_data): Now size_t.
3261 (check_memory_limits): Adjust prototypes of real_morecore and
3262 __morecore to receive argument of type ptrdiff_t. Use size_t for

3405 Suggested by Eli Zaretskii in
3406 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
3408 2012-09-30 Eli Zaretskii <eliz@gnu.org>
3410 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
3411 HAVE_TIMER_SETTIME is defined.

3415 Profiler improvements: more-accurate timers, overflow checks.
3416 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
3417 signal.h, setjmp.h. Include systime.h instead.

3425 All uses changed to store the new value.
3426 (handle_profiler_signal): Rename from sigprof_handler_1,
3427 for consistency with other handlers. Do not check whether
3428 cpu_log is a hash-table if garbage collecting, since it
3429 doesn't matter in that case.

3431 for consistency with other handlers.
3432 (setup_cpu_timer): New function, with much of what used to be in
3433 Fprofiler_cpu_start. Check for out-of-range argument.
3434 Prefer timer_settime if available, and prefer
3435 thread cputime clocks, then process cputime clocks, then
3436 monotonic clocks, to the old realtime clock. Use make_timeval
3437 to round more-correctly when falling back to setitimer.
3438 (Fprofiler_cpu_start): Use it.
3439 (Fprofiler_cpu_stop): Prefer timer_settime if available.
3440 Don't assume that passing NULL as the 2nd argument of setitimer

3443 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
3444 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
3445 non-fatal signal handlers. Ignore SIGPROF on startup.
3446 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
3447 in profiler.c, since sysdep.c now uses it.
3449 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

3505 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
3506 Since this stuff is now private to charset.c, there's no need for
3507 a public macro and no need to inline by hand.

3581 (sys_kill): Improve commentary.
3583 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3584 consistency with a signature of a signal handler. All callers
3586 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3587 install term_ntproc as a signal handler for SIGABRT, as that
3588 should be done by the dumped Emacs.

3709 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3711 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3712 fatal_error_backtrace.
3714 * w32proc.c (sys_kill): Undo last change: don't do anything when
3715 invoked to deliver SIGABRT to our own process. This is now
3716 handled by emacs_raise.
3718 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3720 * w32term.c (w32_read_socket): Remove leftover reference to
3721 interrupt_input_pending.
3723 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3725 Do not use SA_NODEFER.
3726 Problem reported by Dani Moncayo in
3727 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3729 * sysdep.c (emacs_abort): Do not reset signal handler.
3730 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3731 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3732 wanted even on POSIXish hosts, and it doesn't work on Windows.
3734 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3736 * xterm.c (x_term_init): Call fixup_locale before and after calling
3737 gtk_init (Bug#12392).
3739 2012-09-23 Chong Yidong <cyd@gnu.org>
3741 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3742 Vdynamic_library_alist.
3744 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3745 (Fgnutls_available_p): Caller changed.
3747 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3748 (Flibxml_parse_xml_region): Likewise.
3750 * dispextern.h (struct image_type): Remove arg from init function.
3752 * image.c (Finit_image_library, lookup_image_type)
3753 (define_image_type): Remove now-unneeded second arg.
3754 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3755 (init_tiff_functions, init_gif_functions, init_svg_functions):
3756 Arglist and w32_delayed_load calling convention changed.
3757 (gs_type): Remove init_gs_functions; there is no such function.
3758 (valid_image_p, make_image): Fix caller to lookup_image_type.
3760 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3762 Simplify and avoid signal-handling races (Bug#12471).
3764 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3765 Avoid recursive loop if there's a fatal error in the function itself.
3766 * atimer.c (pending_atimers):
3767 * blockinput.h: Don't include "atimer.h"; no longer needed.
3768 (interrupt_input_pending): Remove. All uses removed.
3769 pending_signals now counts both atimers and ordinary interrupts.
3770 This is less racy than having three separate pending-signal flags.
3771 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3773 Rename from their upper-case counterparts BLOCK_INPUT,
3774 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3775 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3776 This makes it easier to access volatile variables more accurately.
3777 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3778 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3779 that's more reliable if the code is buggy and sets
3780 interrupt_input_blocked to a negative value. All uses changed.
3781 * atimer.c (deliver_alarm_signal):
3782 Remove. No need to deliver this to the parent; any thread can
3783 handle this signal now. All uses replaced by underlying handler.
3784 * atimer.c (turn_on_atimers):
3785 * dispnew.c (handle_window_change_signal):
3786 * emacs.c (handle_danger_signal):
3787 * keyboard.c (kbd_buffer_get_event):
3788 Don't reestablish signal handler; not needed with sigaction.
3789 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3791 Rework to avoid unnecessary accesses to volatile variables.
3792 (UNBLOCK_INPUT_TO): Now a function.
3793 (totally_unblock_input, unblock_input): New decls.
3794 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3795 (init_data): Remove. Necessary stuff now done in init_signal.
3796 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3797 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3798 (fatal_error_code): Remove; no longer needed.
3799 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3800 it doesn't always backtrace. All uses changed. No need to reset
3801 signal to default, since sigaction and/or die does that for us now.
3802 Use emacs_raise (FOO), not kill (getpid (), FOO).
3803 (main): Check more-accurately whether we're dumping.
3804 Move fatal-error setup to sysdep.c
3805 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3806 * gtkutil.c (xg_get_file_name, xg_get_font):
3807 Remove no-longer-needed signal-mask manipulation.
3808 * keyboard.c, process.c (POLL_FOR_INPUT):
3809 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3810 * keyboard.c (read_avail_input): Remove.
3811 All uses replaced by gobble_input.
3812 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3813 (kbd_buffer_store_event_hold, gobble_input):
3814 (record_asynch_buffer_change) [USABLE_SIGIO]:
3815 (store_user_signal_events):
3816 No need to mess with signal mask.
3817 (gobble_input): If blocking input and there are terminals, simply
3818 set pending_signals to 1 and return. All hooks changed to not
3819 worry about whether input is blocked.
3820 (process_pending_signals): Clear pending_signals before processing
3821 them, in case a signal comes in while we're processing.
3822 By convention callers now test pending_signals before calling us.
3823 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3824 New functions, to support changes to blockinput.h.
3825 (handle_input_available_signal): Now extern.
3826 (reinvoke_input_signal): Remove. All uses replaced by
3828 (quit_count): Now volatile, since a signal handler uses it.
3829 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3830 All callers changed. Block SIGINT only if not already blocked.
3831 Clear sigmask reliably, even if Fsignal returns, which it can.
3832 Omit unnecessary accesses to volatile var.
3833 (quit_throw_to_read_char): No need to restore sigmask.
3834 * keyboard.c (gobble_input, handle_user_signal):
3835 * process.c (wait_reading_process_output):
3836 Call signal-handling code rather than killing ourselves.
3837 * lisp.h: Include <float.h>, for...
3838 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3839 (pending_signals): Now volatile.
3840 (syms_of_data): Now const if IEEE floating point.
3841 (handle_input_available_signal) [USABLE_SIGIO]:
3842 (terminate_due_to_signal, record_child_status_change): New decls.
3843 * process.c (create_process): Avoid disaster if memory is exhausted
3844 while we're processing a vfork, by tightening the critical section
3846 (send_process_frame, process_sent_to, handle_pipe_signal)
3847 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3849 (send_process): No need for setjmp/longjmp any more, since the
3850 SIGPIPE stuff is now gone. Instead, report an error if errno
3852 (record_child_status_change): Now extern. PID and W are now args.
3853 Return void, not bool. All callers changed.
3854 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3855 Remove. All uses removed. This bug should be fixed now in a
3857 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3858 and record the child status change directly. This avoids the
3859 need to futz with the signal mask.
3860 (process_fatal_action): Move here from emacs.c.
3861 (emacs_sigaction_flags): New function, containing
3862 much of what used to be in emacs_sigaction_init.
3863 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3864 caught by emacs, to make races less likely.
3865 (deliver_process_signal): Rename from handle_on_main_thread.
3867 (BACKTRACE_LIMIT_MAX): Now at top level.
3868 (thread_backtrace_buffer, threadback_backtrace_pointers):
3870 (deliver_thread_signal, deliver_fatal_thread_signal):
3871 New functions, for more-accurate delivery of thread-specific signals.
3872 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3873 (deliver_arith_signal): Handle in this thread, not
3874 in the main thread, since it's triggered by this thread.
3875 (maybe_fatal_sig): New function.
3876 (init_signals): New arg DUMPING so that we can be more accurate
3877 about whether we're dumping. Caller changed.
3878 Treat thread-specific signals differently from process-general signals.
3879 Block all signals while handling fatal error; that's safer.
3880 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3882 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3883 Ignore SIGPIPE unless batch.
3884 (emacs_backtrace): Output backtrace for the appropriate thread,
3885 which is not necessarily the main thread.
3886 * syssignal.h: Include <stdbool.h>.
3887 (emacs_raise): New macro.
3888 * xterm.c (x_connection_signal): Remove; no longer needed
3889 now that we use sigaction.
3890 (x_connection_closed): No need to mess with sigmask now.
3891 (x_initialize): No need to reset SIGPIPE handler here, since
3892 init_signals does this for us now.
3894 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3896 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3897 background rect may be larger (Bug#12245).
3899 2012-09-23 Chong Yidong <cyd@gnu.org>
3901 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3903 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3905 * .gdbinit: Just stop at fatal_error_backtrace.
3906 See Stefan Monnier's request in
3907 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3908 Remove no-longer-used query of system type.
3910 2012-09-22 Chong Yidong <cyd@gnu.org>
3912 * search.c (Freplace_match): Doc fix (Bug#12325).
3914 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3916 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3917 (Fline_end_position): Doc fix.
3919 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3921 2012-09-22 Chong Yidong <cyd@gnu.org>
3923 * dispextern.h (struct image_type): Add new slot, storing a type
3924 initialization function.
3926 * image.c (define_image_type): Call the image initializer function
3927 if it is defined. Arguments and return value changed.
3928 (valid_image_p, make_image): Callers changed.
3929 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3930 (gif_type, imagemagick_type, svg_type, gs_type):
3931 Add initialization functions.
3932 (Finit_image_library): Call lookup_image_type.
3933 (CHECK_LIB_AVAILABLE): Macro deleted.
3934 (lookup_image_type): Call define_image_type here, rather than via
3935 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3936 (syms_of_image): Move define_image_type calls for xbm_type and
3937 pbm_type to lookup_image_type.
3939 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3941 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3942 'idle_timers' from here ...
3943 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3944 lists, to avoid infloops when the timer does something stupid,
3945 like reinvoke itself with the same or smaller time-out.
3948 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3950 * window.c (Fsplit_window_internal): Handle only Qt value of
3951 Vwindow_combination_limit separately.
3952 (Qtemp_buffer_resize): New symbol.
3953 (Vwindow_combination_limit): New default value.
3956 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3958 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3959 the new overlay string. (Bug#10159)
3961 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3963 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3964 or that fprintf is async-signal-safe. POSIX doesn't require
3967 2012-09-22 Chong Yidong <cyd@gnu.org>
3969 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3972 2012-09-22 Kenichi Handa <handa@gnu.org>
3974 * composite.c (composition_reseat_it): Handle the case that a
3975 grapheme cluster is not covered by a single font (Bug#12352).
3977 2012-09-21 Chong Yidong <cyd@gnu.org>
3979 * image.c (define_image_type): Avoid adding duplicate types to
3980 image_types (Bug#12463). Suggested by Jörg Walter.
3982 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3984 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3985 (print_load_command_name): Add case LC_DATA_IN_CODE.
3986 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3988 2012-09-21 Glenn Morris <rgm@gnu.org>
3990 * eval.c (Frun_hook_with_args_until_success)
3991 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3993 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3995 * fileio.c (Ffile_selinux_context): Only call freecon when
3996 lgetfilecon succeeded.
3997 (Fset_file_selinux_context): Likewise. (Bug#12444)
3999 2012-09-21 Eli Zaretskii <eliz@gnu.org>
4001 * xdisp.c (try_window_reusing_current_matrix): Under bidi
4002 reordering, locate the cursor by calling set_cursor_from_row; if
4003 that fails, clear the desired glyph matrix before returning a
4004 failure indication to the caller. Fixes leaving garbled display
4005 when fast scrolling with a down-key. (Bug#12403)
4006 (compute_stop_pos_backwards): Fix a typo that caused crashes while
4007 scrolling through multibyte text.
4009 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
4011 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
4012 calling mark_vectorlike since that's the one that marks the window.
4013 (mark_discard_killed_buffers): Mark the final cdr.
4014 * window.h (struct window): Move prev/next_buffers to the
4015 non-standard fields.
4016 * window.c (make_window): Initialize prev/next_buffers manually.
4018 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
4020 Omit unused arg EXPECTED from socket hooks.
4021 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
4022 * nsterm.m (ns_term_init):
4023 * termhooks.h (struct terminal.read_socket_hook):
4024 * w32inevt.c (w32_console_read_socket):
4025 * w32term.c (w32_read_socket):
4026 * xterm.c (XTread_socket):
4027 Omit unused arg EXPECTED. All callers changed.
4028 (store_user_signal_events): Return void, not int, since callers no
4029 longer care about the return value. All uses changed.
4031 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
4033 * w32gui.h (XParseGeometry): Do not declare.
4035 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
4037 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
4038 Ignore 'expected'. See Eli Zaretskii in
4039 <http://bugs.gnu.org/12471#8> (last line).
4041 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
4042 (XParseGeometry): Now static. Substitute extremal values for
4043 values that are out of range.
4045 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
4047 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
4049 * nsfns.m (XParseGeometry): Remove.
4050 (Fx_create_frame): Call x_set_offset to correctly interpret
4051 top_pos in geometry.
4053 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
4054 (Fx_parse_geometry): If there is a space in string, call
4055 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
4057 2012-09-17 Eli Zaretskii <eliz@gnu.org>
4059 * search.c (scan_buffer): Use character positions in calls to
4060 region_cache_forward and region_cache_backward, not byte
4061 positions. (Bug#12196)
4063 * w32term.c (w32_read_socket): Set pending_signals to 1, like
4064 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
4066 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
4067 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
4068 emacs_blocked_malloc, now deleted.
4070 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
4072 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
4073 The workaround was for improving performance on Solaris 2.4, but
4074 is getting in the way now. Emacs will still work if someone is
4075 still running Solaris 2.4 in a museum somewhere; Sun dropped
4076 support for Solaris 2.4 in 2003.
4077 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4078 * process.c (create_process) [HAVE_WORKING_VFORK]:
4079 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4080 since Emacs no longer uses vfork on that platform.
4082 2012-09-17 Glenn Morris <rgm@gnu.org>
4084 * emacs.c: Use COPYRIGHT.
4086 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4088 Remove configure's --without-sync-input option (Bug#12450).
4089 When auditing signal-handling in preparation for cleaning it up,
4090 I found that SYNC_INPUT has race conditions and would be a real
4091 pain to fix. Since it's an undocumented and deprecated
4092 configure-time option, now seems like a good time to remove it.
4093 Also see <http://bugs.gnu.org/11080#16>.
4094 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4095 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4096 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4097 (malloc_hysteresis):
4098 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4099 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4100 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4101 (dont_register_blocks, bytes_used_when_reconsidered)
4102 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4103 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4104 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4105 Remove. All uses removed.
4106 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4107 implementation, one that depends on whether the new macro
4108 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4110 * atimer.c (run_timers, handle_alarm_signal):
4111 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4112 (handle_async_input, process_pending_signals)
4113 (handle_input_available_signal, init_keyboard):
4114 * nsterm.m (ns_read_socket):
4115 * process.c (wait_reading_process_output):
4116 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4117 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4119 * xterm.c (XTread_socket):
4121 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4122 * eval.c (handling_signal): Remove. All uses removed.
4123 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4124 All uses replaced with the SYNC_INPUT version.
4125 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4127 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4130 * font.c (Ffont_shape_gstring): Remove unused local.
4132 2012-09-16 Glenn Morris <rgm@gnu.org>
4134 * Makefile.in (clean): No longer run nextstep's clean.
4136 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4138 (ns-app): Move here from ns.mk, and simplify.
4139 (clean): Simplify nextstep entry.
4140 * ns.mk: Remove file.
4142 2012-09-17 Kenichi Handa <handa@gnu.org>
4144 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4145 not covert the last few charactes.
4147 2012-09-16 Kenichi Handa <handa@gnu.org>
4149 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4150 here, but just check the validity of glyphs in the glyph-string.
4152 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4154 * window.c (Fwindow_parameter, Fset_window_parameter):
4155 Accept any window as argument (Bug#12452).
4157 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4159 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4160 to ns_term_init to avoid memory leak.
4162 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4163 explicit retain/release.
4164 (ns_term_init): Only allow one display. Initialize outerpool and
4167 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4169 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4170 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4171 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4172 the Microsoft problem in a different way, by altering ../nt/config.nt.
4174 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4189 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4190 by lisp.h. This completes removal of setjmp.h inclusion
4191 erroneously announced in the previous commit. (Bug#12446)
4193 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4196 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4197 not defined as a macro. The latter happens on MS-Windows.
4200 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4202 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4203 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4204 Some instances of '#include <setjmp.h>' removed, if the
4205 only reason for the instance was because "lisp.h" was included.
4206 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4207 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4208 and _longjmp with the new symbols. Emacs already uses _setjmp if
4209 available, so this change affects only POSIXish hosts that have
4210 sigsetjmp but not _setjmp, such as some versions of Solaris and
4211 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4212 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4213 (png_load_body) [HAVE_PNG]:
4214 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4215 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4216 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4217 since PNG requires jmp_buf. This is the only exception to the
4218 general rule that we now use sys_setjmp and sys_longjmp.
4219 This exception is OK since this code does not change the signal
4220 mask or longjmp out of a signal handler.
4222 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4224 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4225 Include "syssignal.h", for 'main_thread'.
4227 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4229 Avoid out-of-range marker position (Bug#12426).
4230 * insdel.c (replace_range, replace_range_2):
4231 Adjust markers before overlays, as suggested by comments.
4232 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4233 Remove redundant check before calling offset_intervals.
4235 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4237 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4238 current buffer (Bug#12387).
4240 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4242 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4244 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4246 Use a more backwards-compatible timer format (Bug#12430).
4247 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4248 vector element, not from the 4th, since PSECS is now at the end.
4249 (Fcurrent_idle_time): Doc fix.
4251 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4253 Function to mark objects and remove killed buffers at once.
4254 * alloc.c (discard_killed_buffers): Rename to ...
4255 (mark_discard_killed buffers) ... new name. Add marking
4256 of remaining objects. Fix comment. Adjust users.
4257 (mark_object): Do not touch frame buffer lists here.
4258 * frame.c (delete_frame): Reset frame buffer lists here.
4260 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4262 Better workaround for GNOME bug when --enable-gcc-warnings.
4263 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4264 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4265 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4267 Simplify SIGIO usage (Bug#12408).
4268 The code that dealt with SIGIO was crufty and confusing, e.g., it
4269 played tricks like "#undef SIGIO" but these tricks were not used
4270 consistently. Simplify mostly by not #undeffing standard symbols,
4271 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4272 or not as we please) rather than "defined SIGIO" (standard symbol
4273 that we probably shouldn't #undef).
4274 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4275 Modules that need it can include it.
4276 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4277 * dispextern.h (ignore_sigio): New decl.
4278 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4279 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4280 * emacs.c (shut_down_emacs):
4281 * keyboard.c (kbd_buffer_store_event_hold):
4282 Use ignore_sigio rather than invoking 'signal' directly.
4283 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4285 (FIONREAD, SIGIO): Do not #undef.
4286 (tty_read_avail_input): Use #error rather than a syntax error.
4287 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4288 for I_PIPE, used by SETUP_SLAVE_PTY.
4289 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4290 * sysdep.c (croak): Remove; no longer needed. This bit of
4291 temporary code, with Fred N. Fish's comment that it's temporary,
4292 has been in Emacs since at least 1992!
4293 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4294 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4295 * syssignal.h (croak): Remove decl.
4296 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4297 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4298 now that we're termios-only.
4299 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4300 * term.c (dissociate_if_controlling_tty): Use #error rather than
4303 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4304 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4305 to work around GNOME bug 683906.
4306 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4307 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4308 This works around GCC bug 54561.
4310 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4312 More fixes for 'volatile' and setjmp/longjmp.
4313 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4314 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4315 (png_load_body) [HAVE_PNG]:
4316 (jpeg_load_body) [HAVE_JPEG]:
4317 New function, with most of the old parent function's body.
4318 (png_load) [HAVE_PNG]:
4319 (jpeg_load) [HAVE_JPEG]:
4320 Invoke the new function, to avoid longjmp munging our locals.
4321 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4322 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4323 longjmp is passed 2, as the C standard doesn't guarantee this.
4324 Instead, store the failure code into mgr->failure_code.
4326 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4328 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4329 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4330 (syms_of_keyboard): Remove support for unread-command-char.
4332 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4334 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4335 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4336 violation. (Bug#12426)
4338 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4340 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4342 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4344 * eval.c: Add `inhibit-debugger'.
4345 (Qinhibit_debugger): New symbol.
4346 (call_debugger): Bind it instead of Qdebug_on_error.
4347 (maybe_call_debugger): Test Vinhibit_debugger.
4348 (syms_of_eval): Define inhibit-debugger.
4349 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4350 (syms_of_xdisp): Remove inhibit-debug-on-message.
4352 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4354 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4355 If a nonvolatile local variable is written before a _longjmp to
4356 the frame containing the variable, and is read after the _longjmp,
4357 the value read is indeterminate. Some local variables of type
4358 'struct handler' and 'struct catchtag' are used in this way, so
4359 mark each of their slots as volatile if the slot can be set before
4360 _longjmp and read afterwards.
4361 * lisp.h (struct handler): var and chosen_clause are now volatile.
4362 (struct catchtag): val, next, and pdlcount are now volatile.
4364 * bidi.c (bidi_push_it, bidi_pop_it):
4365 * fns.c (copy_hash_table):
4366 * image.c (define_image_type):
4367 * keyboard.c (kbd_buffer_store_event_hold):
4368 * process.c (Fprocess_send_eof):
4369 * xfaces.c (x_create_gc) [HAVE_NS]:
4370 * xgselect.c (xg_select):
4371 Prefer assignment to memcpy when either will do.
4373 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4374 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4375 time an item is removed. No need to mark this function 'inline';
4376 the compiler knows better than we do.
4378 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4380 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4381 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4382 to change_frame_size (Bug#12388).
4383 (windowDidResize:): Pass YES to updateFrameSize.
4385 * nsterm.h: Add delay parameter to updateFrameSize.
4387 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4389 Discard killed buffers from deleted window and frame objects.
4390 This reduces an amount of references to killed buffers and
4391 helps GC to reclaim them faster.
4392 * alloc.c (discard_killed_buffers): New function.
4393 (mark_object): Use it for deleted windows and frames.
4394 (mark_object): If symbol's value is set up for a killed buffer
4395 or deleted frame, restore its global binding.
4396 * data.c (swap_in_global_binding): Add GC notice.
4397 (swap_in_symval_forwarding): Use convenient set_blv_where.
4398 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4399 * window.h: ... to here.
4401 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4403 Convenient macro to check whether the buffer is live.
4404 * buffer.h (BUFFER_LIVE_P): New macro.
4405 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4406 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4408 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4410 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4411 composition cases (Bug#12364).
4413 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4414 overhang of succeeding glyphs overlapping box cursor.
4416 * w32term.c (x_draw_glyph_string): Likewise.
4418 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4420 Simplify, document, and port floating-point (Bug#12381).
4421 The porting part of this patch fixes bugs on non-IEEE platforms
4422 with frexp, ldexp, logb.
4423 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4425 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4426 support, by removing commented-out code and briefly listing the
4427 C89 functions excluded. The commented-out stuff was confusing
4428 maintenance, e.g., we thought we needed cbrt but it was commented out.
4429 (logb): Remove decl; no longer needed.
4430 (isfinite): New macro, if not already supplied.
4431 (isnan): Don't replace any existing macro.
4432 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4433 are present on all C89 platforms.
4434 (Ffrexp): Do not special-case zero, as frexp does the right thing
4436 (Flogb): Do not use logb, as it doesn't have the desired meaning
4437 on hosts that use non-base-2 floating point. Instead, stick with
4438 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4439 frexp, to avoid getting an unspecified result.
4441 * xdisp.c (Qinhibit_debug_on_message): Now static.
4443 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4445 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4446 NSBezierPath (Bug#12131).
4448 2012-09-10 Chong Yidong <cyd@gnu.org>
4450 * fns.c (Fdelq, Fdelete): Doc fix.
4452 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4454 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4455 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4457 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4459 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4460 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4463 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4465 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4466 left fringe if the window has a left margin. This avoids leaving
4467 traces of the cursor because its leftmost pixel is not drawn over.
4469 * dispnew.c (update_window_line): When the left margin area of a
4470 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4471 that screen line. (Bug#12277)
4473 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4475 Assume C89 or later for math functions (Bug#12381).
4476 This simplifies the code, and makes it a bit smaller and faster,
4477 and (most important) makes it easier to clean up signal handling
4478 since we can stop worring about floating-point exceptions in
4479 library code. That was a problem before C89, but the problem
4480 went away many years ago on all practical Emacs targets.
4481 * data.c, image.c, lread.c, print.c:
4482 Don't include <math.h>; no longer needed.
4483 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4484 might be autoconfigured, as that never happens.
4486 * doprnt.c (DBL_MAX_10_EXP):
4487 * print.c (DBL_DIG):
4488 Remove. C89 or later always defines these.
4489 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4490 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4491 (arith_error, domain_error, domain_error2):
4492 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4493 no longer needed -- we simply return what C returns. All uses removed.
4494 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4496 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4497 Remove. All uses expanded, as these macros are no longer used
4498 more than once and are now more trouble than they're worth.
4499 (Ftan): Use tan, not sin / cos.
4500 (Flogb): Assume C89 frexp.
4501 (fmod_float): Assume C89 fmod.
4502 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4503 (init_floatfns): Remove. All uses removed.
4505 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4507 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4508 compositeToPoint for OSX < 10.6 (Bug#12390).
4510 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4512 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4513 This produces more-accurate results.
4515 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4517 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4518 changes (Bug#12088).
4520 2012-09-08 Chong Yidong <cyd@gnu.org>
4522 * syntax.c (Fstring_to_syntax): Doc fix.
4524 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4526 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4527 in the internal border.
4528 (x_set_window_size): Remove static variables and their usage.
4529 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4530 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4531 Remove fringe/internal border adjustment (Bug#11052).
4532 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4533 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4534 (ns_fix_rect_ibw): Remove.
4535 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4536 (ns_dumpglyphs_box_or_relief): Ditto.
4537 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4539 (ns_dumpglyphs_image): Ditto.
4540 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4542 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4543 their usage. Add fringe_extended_p and its use as in other terms.
4544 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4545 scroll bar was removed.
4546 (updateFrameSize): New function.
4547 (windowDidResize): Move code to updateFrameSize and call it.
4549 * nsterm.h (EmacsView): Add updateFrameSize.
4551 2012-09-07 Chong Yidong <cyd@gnu.org>
4553 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4555 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4557 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4559 More signal-handler cleanup (Bug#12327).
4560 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4561 Problem introduced when merging patches. Noted by Eli Zaretskii in
4562 <http://bugs.gnu.org/12327#67>.
4563 * floatfns.c: Comment fix.
4564 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4565 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4566 and anyway the declaration is harmless even if SIGDANGER is not defined.
4567 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4568 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4569 source files not surprisingly expected syssignal.h to define, or
4570 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4571 Include <sys/ioctl.h>, for FIONREAD.
4572 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4573 This eliminates a problem whereby other files mysteriously had
4574 to include "syssignal.h" before including "systty.h" if they
4575 wanted to use "#ifdef SIGIO".
4577 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4579 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4581 * w32.c (sigemptyset): Empty the set.
4582 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4584 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4586 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4588 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4589 (mark_object): Likewise for frame objects.
4591 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4593 * syssignal.h (handle_on_main_thread): Always declare,
4594 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4595 This ports to platforms without HAVE_PTHREAD.
4597 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4599 Signal-handler cleanup (Bug#12327).
4600 Emacs's signal handlers were written in the old 4.2BSD style with
4601 sigblock and sigmask and so forth, and this led to some
4602 inefficiencies and confusion. Rewrite these to use
4603 pthread_sigmask etc. without copying signal sets around. Also,
4604 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4605 'signal', and instead use functions that do not attempt to take
4606 over the system name space. This patch causes Emacs's text
4607 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4608 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4609 Do not include <signal.h> or "syssignal.h", as these
4610 modules do not use signals.
4611 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4612 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4613 Do not include <signal.h>, as "syssignal.h" does that for us now.
4614 * atimer.c (sigmask_atimers): New function.
4615 (block_atimers, unblock_atimers): New functions,
4616 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4618 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4619 no longer needed here.
4620 * emacs.c (main): Inspect existing signal handler with sigaction,
4621 so that there's no need to block and unblock SIGHUP.
4622 * sysdep.c (struct save_signal): New member 'action', replacing
4623 old member 'handler'.
4624 (save_signal_handlers, restore_signal_handlers):
4625 Use sigaction instead of 'signal' to save and restore.
4626 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4627 New function. All users of 'signal' modified to use set_sighandler
4628 if they're writeonly, and to use sys_signal if they're read+write.
4629 (emacs_sigaction_init, forwarded_signal): New functions.
4630 (sys_signal): Remove. All uses replaced by calls to sigaction
4631 and emacs_sigaction_init, or by direct calls to 'signal'.
4632 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4633 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4634 all uses replaced by pthread_sigmask etc. calls.
4635 * syssignal.h: Include <signal.h>.
4636 (emacs_sigaction_init, forwarded_signal): New decls.
4637 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4638 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4639 (sigmask, sys_sigmask): Remove; no longer needed.
4640 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4641 (sigblock, sigunblock, sigfree):
4642 (sigsetmask) [!defined sigsetmask]:
4643 Remove. All uses replaced by pthread_sigmask.
4644 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4645 no longer need to be replaced, and its typical old uses
4646 are now done via emacs_sigaction_init and sigaction.
4647 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4648 (sys_sigdel): Remove; unused.
4649 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4651 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4653 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4654 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4656 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4658 Explicitly mark buffer_defaults and buffer_local_symbols.
4659 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4660 mark_local_symbols here.
4661 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4662 since special buffers aren't marked here any more.
4663 (allocate_buffer): Chain new buffer with all_buffers here...
4664 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4666 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4667 (syms_of_buffer): Remove staticpro of the above.
4668 (init_buffer_once): Set names for buffer_defaults and
4669 buffer_local_symbols.
4671 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4673 Use bool for booleans in font-related modules.
4674 * font.c (font_intern_prop, font_style_to_value)
4675 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4676 (generate_otf_features, font_check_otf_features, font_check_otf)
4677 (font_match_p, font_list_entities, font_at):
4678 * fontset.c (fontset_id_valid_p, reorder_font_vector
4679 (fontset_find_font, Fset_fontset_font)
4680 (face_suitable_for_char_p) [0]:
4681 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4682 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4683 (m17n_flt_initialized, ftfont_shape_by_flt):
4684 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4685 * nsfont.m (nsfont_draw):
4686 * w32font.c (w32font_draw):
4687 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4688 Use bool for booleans.
4689 * font.h: Adjust to above API changes.
4690 (struct font, struct font_driver, struct font_driver_list):
4691 Use bool for booleans.
4692 (struct font): Remove useless member encoding_type.
4694 * fontset.c, xftfont.c: Omit unnecessary static decls.
4696 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4698 * alloc.c (mark_object): Revert window marking code
4699 since it's unsafe for the Fset_window_configuration.
4701 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4703 Fix race conditions with signal handlers and errno (Bug#12327).
4704 Be more systematic about preserving errno whenever a signal
4705 handler returns, even if it's not in the main thread. Do this by
4706 renaming signal handlers to distinguish between signal delivery
4707 and signal handling. All uses changed.
4708 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4709 * data.c (deliver_arith_signal): Rename from arith_error.
4710 * dispnew.c (deliver_window_change_signal): Rename from
4711 window_change_signal.
4712 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4713 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4714 * keyboard.c (deliver_input_available_signal): Rename from
4715 input_available_signal.
4716 (deliver_user_signal): Rename from handle_user_signal.
4717 (deliver_interrupt_signal): Rename from interrupt_signal.
4718 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4719 (deliver_child_signal): Rename from sigchld_handler.
4720 * atimer.c (handle_alarm_signal):
4721 * data.c (handle_arith_signal):
4722 * dispnew.c (handle_window_change_signal):
4723 * emacs.c (handle_fatal_signal, handle_danger_signal):
4724 * keyboard.c (handle_input_available_signal):
4725 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4726 * process.c (handle_pipe_signal, handle_child_signal):
4727 New functions, with the actual signal-handling code taken from the
4728 original respective signal handlers, sans the sporadic attempts to
4729 preserve errno, since that's now done by handle_on_main_thread.
4730 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4731 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4732 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4734 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4735 Move initialization of main_thread to sysdep.c's init_signals.
4736 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4737 our usage, and simplifies the mainline code.
4738 (record_child_status_change): New static function, as a helper
4739 for handle_child_signal, and with most of the old child handler's
4741 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4742 (handle_child_signal): Use the above.
4743 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4744 Moved here from emacs.c.
4745 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4746 code moved here from emacs.c's main function.
4747 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4748 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4749 This lets callers save and restore errno properly.
4751 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4753 Remove redundant or unused things here and there.
4754 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4755 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4756 * editfns.c (Fcompare_buffer_substrings): Likewise.
4757 * frame.h (struct terminal, struct font_driver_list):
4758 Remove redundant declarations.
4759 * window.h (Qleft, Qright): Likewise.
4761 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4763 Do not mark objects from deleted buffers, windows and frames.
4764 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4765 (mark_object): Likewise for windows and frames.
4767 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4769 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4770 buffer_defaults and buffer_local_symbols as valid objects.
4771 Return special value to denote them.
4773 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4775 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4776 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4777 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4778 (file_name_absolute_p, Fsubstitute_in_file_name):
4779 (check_executable, check_writable, Ffile_accessible_directory_p)
4780 (Fset_file_selinux_context, Fdefault_file_modes)
4781 (Finsert_file_contents, choose_write_coding_system)
4782 (Fwrite_region, build_annotations, a_write, e_write)
4784 * filelock.c (boot_time_initialized, get_boot_time)
4785 (get_boot_time_1, lock_file_1, within_one_second):
4786 * floatfns.c (in_float):
4787 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4788 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4789 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4790 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4791 * window.c (compare_window_configurations):
4792 Use bool for booleans.
4793 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4794 (Fdefault_file_modes): Now mode_t, not int, for modes.
4795 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4796 (internal_delete_file): Now returns void, not a (boolean) int,
4797 since nobody was looking at the return value.
4798 * lisp.h, window.h: Adjust to above API changes.
4800 * xdisp.c (set_message): Simplify and reindent last change.
4802 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4804 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4806 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4808 * eval.c (call_debugger): Make the function non-static so that we
4809 can call it from set_message.
4811 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4812 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4814 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4816 Give more-useful info on a fatal error (Bug#12328).
4817 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4818 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4819 of doing the work ourselves.
4820 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4821 do most of the work.
4822 (fatal_error_backtrace): New function, taken from the guts
4823 of the old fatal_error_signal, but with a new option to output
4825 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4826 info about the signal than just its number.
4827 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4828 * sysdep.c: Include <execinfo.h>
4829 (emacs_backtrace): New function, taken partly from the previous
4830 code of the 'die' function.
4831 (emacs_abort): Call fatal_error_backtrace rather than abort.
4833 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4835 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4836 eager (load-time) macro-expansion.
4837 * lisp.mk (lisp): Add macroexp.
4839 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4841 Simplify redefinition of 'abort' (Bug#12316).
4842 Do not try to redefine the 'abort' function. Instead, redo
4843 the code so that it calls 'emacs_abort' rather than 'abort'.
4844 This removes the need for the NO_ABORT configure-time macro
4845 and makes it easier to change the abort code to do a backtrace.
4846 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4847 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4848 Remove; sysdep.c's emacs_abort now takes its place.
4849 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4850 'abort' changed to use 'emacs_abort'.
4851 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4852 (abort) [!defined abort]: Rename to ...
4853 (emacs_abort): ... new name.
4854 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4855 the place of the old 'abort' in emacs.c.
4856 * w32.c, w32fns.c (abort): Do not #undef.
4857 * w32.c (emacs_abort): Rename from w32_abort.
4859 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4861 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4862 offsets[j].dv, since the y axis of the screen coordinates points
4863 down, while the y axis of the font definition coordinates points
4864 up. This fixes display of Arabic diacritics such as KASRA and
4865 KASRATAN. (Bug#11860)
4867 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4869 Be more systematic about _setjmp vs setjmp.
4870 * alloc.c (test_setjmp, mark_stack):
4871 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4872 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4873 (png_load, my_error_exit, jpeg_load):
4874 * process.c (send_process_trap, send_process):
4875 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4876 The underscored versions are up to 30x faster on some hosts.
4877 Formerly, the code used setjmp+longjmp sometimes and
4878 _setjmp+_longjmp at other times, with no particular reason to
4879 prefer setjmp+longjmp.
4881 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4883 Fix minor problem found by static checking.
4884 * buffer.c (Fdelete_all_overlays): Return nil.
4886 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4888 * buffer.c (Fdelete_all_overlays): New function.
4890 2012-09-03 Chong Yidong <cyd@gnu.org>
4892 * gtkutil.c: Add extern decl for Qxft.
4894 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4896 * emacs.c, eval.c: Use bool for boolean.
4897 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4898 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4899 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
4900 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
4901 (main, decode_env_path, Fdaemon_initialized):
4902 * eval.c (call_debugger, Finteractive_p, interactive_p):
4903 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4904 (maybe_call_debugger, Fbacktrace):
4905 * process.c (read_process_output, exec_sentinel):
4906 Use bool for booleans.
4907 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4908 All callers changed.
4909 * eval.c (interactive_p): Omit always-true boolean argument
4910 EXCLUDE_SUBRS_P. All callers changed.
4911 * dispextern.h, lisp.h: Reflect above API changes.
4912 * firstfile.c (dummy): Use the address of 'main', whose signature
4913 won't change, instead of the address of 'initialize', whose
4914 signature just changed from int to bool.
4915 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4916 * msdos.c (fatal_error_in_progress): ... from here.
4917 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4919 (redisplay_internal, unwind_redisplay): Simply clear
4920 REDISPLAYING_P when unwinding, instead of saving its previous,
4921 always-false value and then restoring it.
4923 Clean up some extern decls.
4924 Mostly, this hoists extern decls out of .c files and into .h files.
4925 That way, we're more likely to catch errors if the interfaces change.
4926 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4927 declare xg_mark_data.
4928 * dispextern.h (x_frame_parm_handlers):
4930 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4931 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4932 (Qultra_bold, Qoblique, Qitalic):
4933 Move extern decl here from .c file.
4934 * alloc.c (xg_mark_data) [USE_GTK]:
4936 * eval.c (Qlexical_binding):
4937 * fns.c (time) [!HAVE_UNISTD_H]:

4943 * process.c (QCfamily, QCfilter):
4944 * widget.c (free_frame_faces):
4945 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
4946 * xfont.c (x_clear_errors):
4947 * xterm.c (x_frame_parm_handlers):
4948 Remove now-redundant extern decls.
4949 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4950 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4952 * xfaces.c: Remove unnecessary static decls.
4953 * xterm.c (updating_frame): Remove decl of nonexistent object.
4955 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4956 when building globals.h, as the objects that are not built on
4957 this host are not needed to compile C files on this host.
4959 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4961 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4963 * frame.h: Add missing prototype for x_wm_set_size_hint.
4965 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4967 * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean.

4969 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
4970 (Fsubstitute_command_keys):

4975 (make_buffer_string, make_buffer_string_both)
4976 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

4988 (set_intervals_multibyte_1, set_intervals_multibyte):
4989 * keyboard.c (decode_timer):
4990 Use bool for boolean.
4991 * intervals.h, lisp.h, systime.h: Reflect above API changes.
4992 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
4994 2012-09-02 Chong Yidong <cyd@gnu.org>
4996 * keymap.c (push_key_description): Print M-TAB as C-M-i
4999 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
5001 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
5002 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))
5003 ($(BLD)/editfns.$(O), $(BLD)/ccl.$(O), $(BLD)/chartab.$(O))

5007 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
5009 2012-09-01 Eli Zaretskii <eliz@gnu.org>
5011 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
5012 more than one grapheme cluster passed to the shaper: compute the
5013 offset adjustment values separately for each cluster. (Bug#11860)
5015 * image.c: Restore mistakenly removed inclusion of w32.h. Without
5016 it, GCC doesn't see prototypes of w32_delayed_load, and complains

5336 Special MEM_TYPE_SPARE to denote reserved memory.
5337 * alloc.c (enum mem_type): New memory type.
5338 (refill_memory_reserve): Use new type for spare memory.

5374 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5375 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5376 are all boolean, so make them single-bit bitfields.
5378 * lisp.h (ASET): Remove attempt to detect side effects.
5379 It was meant to be temporary and it often doesn't work,
5380 because when IDX has side effects the behavior of IDX==IDX
5381 is undefined. See Stefan Monnier in
5382 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5384 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)

5387 (FUNCTIONP): Use it.

5392 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5393 as that's faster and simpler than static storage. Don't bother
5394 with the g_main_context_query overhead if g_main_context_pending
5395 says no events are pending.
5396 (gfds, gfds_size): Remove these static vars.
5397 (xgselect_initialize): Remove; no longer needed.
5398 All uses and decls removed.
5400 * emacs.c (fatal_error_signal_hook): Remove.
5401 All uses removed. This leftover from old code was always 0.

5428 Use bool for booleans, instead of int.
5429 * lisp.h, process.h: Adjust prototypes to match above changes.
5430 * callint.c (Fcall_interactively): Don't assume the mark's
5431 offset fits in 'int'.

5444 Use bool for booleans, instead of int.
5445 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5446 since the 1-or-0 return value is always ignored anyway.
5447 (mmap_initialized_p):
5448 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5449 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5451 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5453 * bidi.c: Use bool for boolean.
5454 This is a bit more readable, and makes the text segment of bidi.o
5455 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).

5475 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5476 * atimer.h: Include <stdbool.h>.
5478 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5480 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5481 compile time tests instead of run time tests on systems that do
5483 (FRAME_MAC_P): Remove leftover from deleted code.
5484 * frame.c (syms_of_frame): Remove leftover from deleted code.
5486 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

5490 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5492 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5493 Otherwise, the compiler complains about (A?B:C) where B is void
5494 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5495 (fontset_add): Return void, for FONTSET_ADD.
5497 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5499 * alloc.c: Use bool for booleans.
5500 (gc_in_progress, abort_on_gc)
5501 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5502 (dont_register_blocks) [GC_MALLOC_CHECK]:
5503 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5504 (check_string_bytes, make_specified_string, memory_full)
5505 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5506 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5507 (mark_stack, valid_pointer_p, make_pure_string)
5508 (Fgarbage_collect, survives_gc_p, gc_sweep):
5509 Use bool for booleans, instead of int.
5510 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5511 Remove unused local.
5512 * alloc.c (PURE_POINTER_P):
5513 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5514 * editfns.c (Fformat):
5515 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5517 * fns.c (sweep_weak_table):
5518 * lisp.h (suppress_checking, push_message, survives_gc_p)
5519 (make_pure_string, gc_in_progress, abort_on_gc):
5520 * lread.c (readchar, read1):
5521 * print.c (Fprin1_to_string):
5522 * xdisp.c (push_message):
5523 Use bool for booleans affected directly or indirectly by
5526 Make recently-introduced setters macros.
5527 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5528 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5529 (set_fontset_default, set_fontset_fallback): Rename from their
5530 upper-case counterparts, and make them functions rather than macros.
5531 This is more consistent with the other recently-introduced setters.
5532 These don't need to be inline, since they're local.
5534 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5536 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5537 the loop (Bug#12247).
5539 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5541 * lisp.h (vcopy): Use memcpy rather than our own loop.
5542 This fixes a performance regression introduced by the recent
5543 addition of vcopy. This means 'vcopy' will need to be modified
5544 for a copying collector, but that's OK. Also, tighten the
5545 checking in the assertion.
5547 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5549 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5550 components for RTL text (Bug#11860). Adjust X-OFFSET of each
5551 non-base glyph for the width of the base character, according to
5552 what x_draw_composite_glyph_string_foreground expects.
5553 Generate WADJUST value according to composition_gstring_width's
5554 expectations, to produce correct width of the composed character.
5555 Reverse the sign of the DU offset produced by ScriptPlace.
5557 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5559 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
5561 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5563 Avoid direct writes to contents member of struct Lisp_Vector.
5564 * lisp.h (vcopy): New function to copy data into vector.
5565 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
5566 * fns.c (Ffillarray): Use ASET.
5567 * keyboard.c (timer_check_2): Use AREF and ASET.
5568 (append_tool_bar_item, Frecent_keys): Use vcopy.
5569 * lread.c (read_vector): Use ASET.
5570 * msdos.c (Frecent_doskeys): Use vcopy.
5571 * xface.c (Finternal_copy_lisp_face): Use vcopy.
5572 (Finternal_merge_in_global_face): Use ASET and vcopy.
5573 * xfont.c (xfont_list_pattern): Likewise.
5575 2012-08-21 Martin Rudalics <rudalics@gmx.at>

5578 the position of its buffer's point.
5579 (Fset_window_point): For the selected window always go in its
5580 buffer to the specified position.
5582 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
5584 Setter macros for fontsets.
5585 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
5586 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
5587 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
5590 2012-08-20 Glenn Morris <rgm@gnu.org>
5592 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
5593 Don't assume that `ln -f' works.
5595 2012-08-20 Eli Zaretskii <eliz@gnu.org>
5597 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
5598 and later about non-assignments with no effect. See discussion at
5599 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
5602 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5604 Inline setter functions for Lisp_Objects slots of struct specbinding.
5605 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
5608 2012-08-20 Martin Rudalics <rudalics@gmx.at>
5610 * window.c (select_window): Always make selected window's buffer
5613 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5615 Use AREF and ASET for docstrings of category tables.
5616 * category.h (CATEGORY_DOCSTRING): Use AREF.
5617 (SET_CATEGORY_DOCSTRING): Use ASET.
5618 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
5620 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5622 Inline setter functions for hash table members.
5623 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
5624 (set_hash_hash, set_hash_index): Rename with _slot suffix.
5625 (set_hash_key_and_value, set_hash_index, set_hash_next)
5626 (set_hash_hash): New functions.
5627 * charset.c, fns.c: Adjust users.
5629 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
5631 Inline getter and setter functions for per-buffer values.
5632 * buffer.h (per_buffer_default, set_per_buffer_default)
5633 (per_buffer_value, set_per_buffer_value): New functions.
5634 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
5635 * buffer.c, data.c: Adjust users.
5637 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
5639 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
5641 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
5643 Rely on <config.h> + <unistd.h> to declare 'environ',
5644 as gnulib does this if the system doesn't.
5645 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
5646 Remove declaration. MS-Windows declares it on stdlib.h which is
5647 included by conf_post.h.
5648 * emacs.c (environ) [DOUG_LEA_MALLOC]:
5649 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
5650 * vm-limit.c: Include <unistd.h>, for 'environ'.
5652 * unexaix.c, unexcoff.c: Include "mem-limits.h".
5653 (start_of_data): Remove decl; mem-limits.h provides it.
5655 * xdisp.c (handle_invisible_prop): Make it a bit faster
5656 and avoid a gcc -Wmaybe-uninitialized diagnostic.
5658 2012-08-19 Chong Yidong <cyd@gnu.org>
5660 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
5663 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
5665 * .gdbinit: Use call instead of set when calling a function in the
5668 * data.c (set_internal): Don't use set_blv_found.
5669 (Fkill_local_variable): Likewise.
5671 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
5673 * nsfont.m (ns_ascii_average_width): Ensure the string
5674 ascii_printable is initialized with a null-terminated character
5675 array. Otherwise, it can contain undesired extra characters.
5677 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
5679 port new setting code to Sun C 5.8 2005/10/13
5680 * chartab.c, lisp.h (char_table_set, char_table_set_range):
5681 Return void, not Lisp_Object. Otherwise, the compiler
5682 complains about (A?B:C) where B is void and C is Lisp_Object
5683 when compiling CHAR_TABLE_SET, due to the recent change to
5684 the API of sub_char_table_set_contents.
5686 2012-08-18 Chong Yidong <cyd@gnu.org>
5688 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
5689 for the string case (Bug#3874).

5844 The old version was confusing because it used the same name
5845 'parent' for two different things.
5847 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>
5849 Functions to get and set Lisp_Object fields of buffer-local variables.

5859 directly-specified attributes.
5860 (merge_face_ref): Recognize :font.
5862 2012-08-17 Dmitry Antipov <dmantipov@yandex.ru>

6516 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6517 * w32.c (init_environment): Change the default values of many
6518 environment variables in dflt_envvars[] to NULL, to avoid pushing
6519 them into environment when they were not already defined.
6520 Remove the code that deletes site-lisp subdirectories from the default
6521 value of EMACSLOADPATH, as it is no longer needed.
6522 (check_windows_init_file): Now external, not static.
6523 Use Vload_path as is, without adding anything, as this function is now
6524 called when Vload_path is already set up.
6526 * w32.h (check_windows_init_file): Add prototype.
6528 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

6535 installation tree, as appropriate.
6537 * callproc.c (init_callproc_1): Call decode_env_path instead of
6538 doing its equivalent by hand.

6540 the code that sets Vexec_path run on MS-Windows.
6542 * lread.c (init_lread): Add comments to #ifdef's.
6544 * msdos.c (dos_set_window_size, IT_update_begin)

6556 Remove unnecessary casts involving pointers.
6557 These casts are no longer needed now that we assume C89 or later,

6571 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6572 Remove unnecessary pointer casts.
6573 * alloc.c (record_xmalloc): New function.
6574 * lisp.h (record_xmalloc): New decl.
6575 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6576 more like a function. This is because the pointer cast is not
6577 needed. All uses changed.
6578 * print.c (print_string, print_error_message): Avoid length recalc.
6580 Improve fix for macroexp crash with debugging (Bug#12118).
6581 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6582 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6583 not supposed to be invoked from the garbage collector.
6584 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
6585 (gc_aset): New function, which is like ASET but can be
6586 used in the garbage collector.
6587 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

6602 headers (most versions of MinGW w32api don't).
6603 (get_security_info, create_symbolic_link)
6604 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):

6615 with addition of handling of symlinks and support for 'lstat'.
6616 If possible, get file's attributes and security information by
6617 handle, not by name. Produce S_IFLNK bit for symlinks, when
6618 called from 'lstat'.
6619 (stat, lstat): New functions, call 'stat_worker'.
6620 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6621 symlinks when the underlying filesystem supports them.
6623 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6625 Fix macroexp crash on Windows with debugging (Bug#12118).
6626 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6627 checking subscripts; problem introduced with the recent
6628 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6629 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6630 since it's used in non-static inline functions now.
6632 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6633 Don't assume buffer size fits in 'int'. Remove unused local.

6650 * category.c (CATEGORY_INLINE):
6651 * character.c (CHARACTER_INLINE):
6652 * charset.c (CHARSET_INLINE):
6653 * composite.c (COMPOSITE_INLINE):
6654 * dispnew.c (DISPEXTERN_INLINE):
6655 * sysdep.c (SYSTIME_INLINE):
6656 Define to EXTERN_INLINE, so that the corresponding functions
6657 are compiled into code.
6658 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6659 (INLINE_HEADER_END): New macros.
6660 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6680 hard-coding the path separator.
6682 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6684 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6685 This how ASET and AREF are supposed to work, and makes
6686 it easier to think about future improvements. See
6687 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6688 * charset.h (set_charset_attr): New function.

7180 the fix for 12036 would have avoided some of the problems noted in
7181 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7182 would have been more obvious.

7192 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7193 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7194 not be usable in #if. This simplifies things.
7196 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7198 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

7203 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7204 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7205 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7206 Adjust to changes in lisp.h and emacs.c, by using

7209 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of

7211 instead of gdb_valbits.
7212 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7213 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG

7215 (xboolvector): Get size from $->size, not $->header.size.
7216 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7217 (xreload, hook-run, hookpost-run): Remove.
7218 * emacs.c: Include <verify.h>.
7219 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7220 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7222 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)

8111 (menu_separator_name_p):

8113 Prefer memcmp to strncmp when either will do.
8114 * nsterm.m: Include <ftoastr.h>.
8116 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8117 Prefer snprintf to strncpy.
8118 * nsterm.m (ns_term_init):
8119 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8120 * nsterm.m (ns_term_init):
8121 Avoid the need for strncpy, by using build_string or
8122 make_unibyte_string directly. Use dtoastr, not snprintf.
8123 * process.c (Fmake_network_process): Diagnose service names that
8124 are too long, rather than silently truncating them or creating
8125 non-null-terminated names.

8155 Optimize pure C strings initialization.
8156 * lisp.h (make_pure_string): Fix prototype.
8157 (build_pure_c_string): New function, defined as static inline. This
8158 provides a better opportunity to optimize away calls to strlen when
8159 the function is called with compile-time constant argument.
8160 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
8161 argument, adjust users accordingly. Use build_pure_c_string where
8163 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
8164 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
8165 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
8167 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
8169 Avoid calls to strlen in miscellaneous functions.
8170 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
8171 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
8172 * lread.c (openp): Likewise.

8176 Avoid calls to strlen in path processing functions.
8177 * fileio.c (file_name_as_directory): Add comment. Change to add
8178 srclen argument and return the length of result. Adjust users

8182 Adjust users accordingly.
8183 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
8185 2012-07-10 Glenn Morris <rgm@gnu.org>

8192 * s/gnu.h (DATA_START): Move definitions to configure.
8194 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
8195 We include usg5-4-common.h, which defines them both.
8197 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8198 O_RDONLY already includes it).
8200 Stop ns builds setting the EMACSLOADPATH environment variable.
8201 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8202 Now it does not set EMACSLOADPATH, just returns the load-path string.
8203 * nsterm.h: Update accordingly.
8204 * lread.c [HAVE_NS]: Include nsterm.h.
8205 (init_lread) [HAVE_NS]: Use ns_load_path.

8208 2012-07-09 Glenn Morris <rgm@gnu.org>
8210 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8211 since the included bsd-common.h does so.
8213 Stop ns builds setting the EMACSPATH environment variable.
8214 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8215 (ns_init_paths): Do not set EMACSPATH.
8216 * nsterm.h (ns_exec_path): Add it.
8217 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8220 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8222 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8224 * process.c (wait_reading_process_output): 'waitchannels' was unset
8225 when read_kbd || !NILP (wait_for_cell); fix this.
8227 Add GCC-style 'const' attribute to functions that can use it.
8228 * character.h (char_resolve_modifier_mask):
8229 * keyboard.h (make_ctrl_char):
8230 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

8239 Add decls with ATTRIBUTE_CONST.
8241 Minor improvements to make_formatted_string.
8242 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8243 where int is good enough, as vsprintf returns an int.
8244 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8246 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8248 Use make_formatted_string to avoid double length calculation.
8249 * lisp.h (make_formatted_string): New prototype.
8250 * alloc.c (make_formatted_string): New function.
8251 * buffer.c (Fgenerate_new_buffer_name): Use it.

8273 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8275 Move marker debugging code under MARKER_DEBUG.
8276 * marker.c (MARKER_DEBUG): Move marker debugging code under
8277 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8278 for bootstrap with --enable-checking (~3x slowdown reported
8279 by Juanma Barranquero <lekktu@gmail.com>).
8280 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8282 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8284 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8285 See <http://bugs.gnu.org/11825#29>.
8287 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8289 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8290 has no font, use the frame's font. (Bug#11813)
8291 (display_line): Add commentary about displaying truncation glyphs
8293 (produce_special_glyphs): Move here from term.c.
8295 * term.c (produce_special_glyphs): Move to xdisp.c.
8297 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8300 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8302 * xdisp.c (display_line): Avoid warning about implicit declaration
8305 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8307 * lisp.h: Remove empty conditional.
8309 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8311 * lread.c (load_path_check): Now static.
8313 Fix some minor --with-ns problems found by static checking.
8314 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8315 (x_set_font) [!HAVE_X_WINDOWS]:
8316 * image.c (xpm_load_image) [HAVE_NS]:
8317 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8318 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8319 Remove unused local.
8320 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8321 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8322 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8323 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8324 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8325 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8326 Fix pointer signedness problem.
8327 * xfaces.c (FRAME_X_FONT_TABLE):
8328 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8330 2012-07-07 Glenn Morris <rgm@gnu.org>
8332 * lread.c (load_path_check): New function, split from init_lread.
8333 (init_lread): Reorganize. Motivation:
8334 If EMACSLOADPATH is set, check/warn about that rather than the
8335 defaults, which we are not going to use. Hence we can remove
8336 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8337 Don't warn if site-lisp directories are missing.
8338 If not installed, start from a blank load-path, since
8339 PATH_LOADSEARCH refers to the eventual installation directories.
8341 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8343 Support truncation and continuation glyphs on GUI frames, when
8344 fringes are disabled. (Bug#11832)
8345 * xdisp.c (init_iterator): Get dimensions of truncation and
8346 continuation glyphs even if on GUI frames.
8347 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8348 or both, are absent.
8349 (start_display, move_it_in_display_line_to): Handle the case of a
8350 GUI frame without a fringe to display continuation or truncation
8352 (insert_left_trunc_glyphs): Support GUI frames: make sure
8353 truncation glyphs overwrite enough glyphs from the current line to
8354 have sufficient space in pixels.
8355 (display_line): Support truncation and continuation glyphs on GUI
8356 frames. If some spare pixels are left on the line after inserting
8357 the truncation glyphs, fill that space with a stretch glyph of a
8358 suitably computed width.
8360 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8361 produce_glyphs, to support GUI sessions.
8363 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8365 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8367 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8369 Do not require float-time's arg to fit in time_t (Bug#11825).
8370 This works better on hosts where time_t is unsigned, and where
8371 float-time is applied to the (negative) difference between two times.
8372 * editfns.c (decode_time_components): Last arg is now double *,
8373 not int *, and means to store all the result as a double, without
8374 worrying about whether the seconds part fits in time_t.
8375 All callers changed.
8376 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8377 All callers changed.
8378 (Ffloat_time): Do not fail merely because the specified time falls
8379 outside of time_t range.
8381 2012-07-07 Glenn Morris <rgm@gnu.org>
8383 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8390 Update dependencies.
8392 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
8394 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

8398 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8399 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8400 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

8403 * xfont.c (compare_font_names): Redo to omit the need for casts.
8405 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8407 * xfns.c (Fx_change_window_property): Doc fix.
8408 * w32fns.c (Fx_change_window_property): Doc fix.
8410 * w32fns.c (Fx_window_property): Accept the same arguments as the
8411 X Windows version. Doc fix.
8412 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8414 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8415 Eli Zaretskii <eliz@gnu.org>
8417 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8418 Windows-specific code from nt/config.nt moved here.
8419 Obsolete settings removed.
8421 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8423 * process.c: Avoid unnecessary calls to gettime.
8424 (wait_reading_process_output): Don't get the time of day
8425 when gobbling data immediately and not waiting, as there's no need
8426 for it in that case. This removes a FIXME.
8428 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8430 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8431 is defined (Bug#11768).
8433 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8435 Fix marker debugging code.
8436 * marker.c (byte_char_debug_check): Do not perform the check
8437 if buffer is not multibyte.
8438 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8439 Call byte_char_debug_check with correct arguments.
8441 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8443 Compile marker debugging code only if ENABLE_CHECKING is defined.
8444 * marker.c (byte_char_debug_check, count_markers):
8445 Use only if ENABLE_CHECKING is defined.
8446 (byte_debug_flag): Remove.
8447 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8448 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8450 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8452 Avoid code repetition in marker-related functions.
8453 * marker.c (attach_marker): New function.
8454 (Fset_marker, set_marker_restricted, set_marker_both)
8455 (set_marker_restricted_both): Use it.
8456 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8457 Consistently rename charno to charpos.
8458 (marker_position): Add eassert.
8459 (marker_byte_position): Convert to eassert.

8478 * window.c (save_window_save): Likewise.
8480 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8482 Do not use Fdelete_overlay in delete_all_overlays
8483 to avoid redundant calls to unchain_overlay.
8484 * buffer.c (drop_overlay): New function.
8485 (delete_all_overlays, Fdelete_overlay): Use it.
8486 * minibuf.c (get_minibuffer): Fix comment.
8488 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8490 Port to OpenBSD 5.1 amd64.
8491 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8492 This is needed for OpenBSD, and should be harmless on all BSD systems.
8493 Also, include <sys/sysctl.h>, as it should be available on all
8494 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8495 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8496 use p_pid member, not kp_proc.pid.
8498 2012-07-06 Glenn Morris <rgm@gnu.org>
8500 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8502 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8504 More xmalloc and related cleanup.

8513 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8515 Omit needless casts involving void * pointers and allocation.
8516 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8517 as the former is more robust if P's type is changed.
8518 Prefer xzalloc to xmalloc + memset 0.
8519 Simplify malloc-or-realloc to realloc.
8520 Don't worry about xmalloc returning a null pointer.
8521 Prefer xstrdup to xmalloc + strcpy.
8522 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8524 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8525 alloca of a constant.
8527 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8529 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8530 hscroll is larger than the line width. Fixes long and futile
8531 looping inside extend_face_to_end_of_line (on a TTY) producing
8532 glyphs that are not needed and thrown away.
8534 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8536 * marker.c (set_marker_restricted_both): Simplify by using

8562 * xdisp.c (window_hscroll_limited): New function.
8563 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8564 coordinates when window's hscroll is set to insanely large
8567 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8569 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
8570 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

8630 * fileio.c (time_error_value): Check the right error number.
8631 Problem reported by Troels Nielsen in
8632 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
8634 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8636 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8637 This should be fixed in a better way; see Eli Zaretskii in
8638 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8639 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8641 * fileio.c (time_error_value): Rename from special_mtime.
8642 The old name's problems were noted by Eli Zaretskii in
8643 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8645 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8646 This variable's comment says Emacs needs at least one GDB-visible
8647 symbol of type enum pvec_type, to work around GDB problems.
8648 The symbol's value doesn't matter.
8650 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8651 that causes compilation to fail on pre-C99 compilers.
8653 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8655 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
8656 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
8658 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8660 * buffer.c (init_buffer_once): Fix initialization of
8661 headers for buffer_defaults and buffer_local_symbols.
8662 Reported by Juanma Barranquero <lekktu@gmail.com>.
8664 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
8666 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8667 * lisp.h (enum pvec_type): Use fewer bits.
8668 (PSEUDOVECTOR_SIZE_BITS): New constant.
8669 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8670 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8671 change in pvec_type.
8672 (PSEUDOVECTOR_TYPEP): New macro.

8676 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
8677 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
8678 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8679 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8680 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8681 abusing vector->header.next.nbytes.
8682 (live_vector_p): Use PVEC_TYPE.
8683 (mark_object): Adapt code to extract pvectype. Use switch.
8685 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8687 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8688 Tighten new eassert a bit.
8690 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8692 Fix compilation with --enable-gcc-warnings and -O1
8694 * doprnt.c (doprnt): Change type of tem to int, initialize
8695 to avoid compiler warning. Add eassert.
8696 * search.c (simple_search): Initialize match_byte to avoid
8697 compiler warning. Add eassert.
8699 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8701 Avoid weird behavior with large horizontal scrolls.
8702 Without this change, for example, large hscroll values would
8703 mess up Emacs's display on Fedora 15 x86, presumably due to
8704 overflows in int calculations in the display code.
8705 Also, if buffers had long lines, Emacs would freeze.
8706 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8707 (set_window_hscroll): New function, containing the old guts of
8708 Fset_window_hscroll. Return the clipped value.
8709 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8710 This avoids the need to check against PTRDIFF_MAX.
8712 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8714 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8716 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8718 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8720 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8721 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8722 since GCC 4.4.6 issues a bogus warning for them.
8724 Fix bugs in file timestamp newness comparisons.
8725 * fileio.c (Ffile_newer_than_file_p):
8726 * lread.c (Fload): Use full timestamp resolution of files,
8727 not just the 1-second resolution, so that files that are only
8728 slightly newer still count as newer.
8729 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8730 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8732 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8734 * fileio.c: Improve handling of file time marker. (Bug#11852)
8735 (special_mtime): New function.
8736 (Finsert_file_contents, Fverify_visited_file_modtime):
8737 Use it to set special mtime values consistently.
8739 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8741 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8742 marker for non-existing file. (Bug#11852)
8744 2012-07-03 Glenn Morris <rgm@gnu.org>
8746 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8747 and did not make it into globals.h).
8749 2012-07-03 Tom Tromey <tromey@redhat.com>
8751 * window.c (Fset_window_margins, Fset_window_fringes)
8752 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8753 * textprop.c (Fprevious_property_change): No longer static.
8754 * syntax.c (Fsyntax_table_p): No longer static.

8776 * intervals.h: Remove EXFUNs.
8777 * fontset.h: Remove EXFUN.

8785 * xterm.h: Remove EXFUN.
8787 2012-07-03 Glenn Morris <rgm@gnu.org>
8789 * lisp.h (Frandom): Make it visible to C.
8790 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8791 buffer for invisible buffers. (Bug#1229)
8793 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8795 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8796 values which aren't power of 2.
8797 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8798 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8801 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8803 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8805 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8807 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8809 * alloc.c (allocate_vector_block): Remove redundant
8810 calls to mallopt if DOUG_LEA_MALLOC is defined.
8811 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8812 avoid calls to mallopt if zero_vector is returned.
8814 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8816 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8817 is enabled, avoid dereferencing NULL current_sblock if
8820 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8822 Cleanup basic buffer management.
8823 * buffer.h (struct buffer): Change layout to use generic vector
8824 marking code. Fix some comments. Change type of 'clip_changed'
8825 to bitfield. Remove unused #ifndef old.
8826 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8827 (GET_OVERLAYS_AT): Fix indentation.
8828 (for_each_per_buffer_object_at): New macro.

8832 * alloc.c (allocate_buffer): Adjust to match new layout of
8833 struct buffer. Fix comment.
8834 (mark_overlay): New function.

8837 (mark_object): Use it. Adjust marking of misc objects
8838 and related comments.
8840 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8842 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8843 wrapper that is not needed because the wrapped code is a no-op (zero
8844 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8845 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8847 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8849 * alloc.c (mark_buffer): Simplify. Remove prototype.
8850 (mark_object): Add comment. Reorganize marking of vector-like
8851 objects. Use CHECK_LIVE for all vector-like objects except buffers
8852 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8853 Avoid redundant calls to mark_vectorlike for bool vectors.
8855 2012-06-30 Glenn Morris <rgm@gnu.org>
8857 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8859 * epaths.in (PATH_SITELOADSEARCH): New.
8860 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8861 This is rather than relying on --enable-locallisppath elements
8862 having "site-lisp" in their names. (Bug#10208#25, 11658)
8864 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8866 * w32proc.c (sys_select): Accept and ignore one more argument.
8868 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8870 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8871 (pselect) [!MS_DOS]: Redirect to sys_select.
8873 * sysdep.c: Don't include dos.h and dosfns.h.
8875 * process.c (sys_select):
8876 * msdos.c (sys_select): Accept one more argument and ignore it.
8878 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8879 adapt data types and code to that.
8882 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8883 which clashes with the gnulib function of the same name.
8885 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8887 * font.c (font_style_to_value, font_style_symbolic)
8888 (font_prop_validate_style): Add type checks for values in
8891 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8893 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8896 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8898 * xdisp.c (try_window_id): Undo last change.
8900 * w32.c (getwd): Adjust commentary about startup_dir.
8901 (init_environment): Always call sys_access, even in non-MSVC
8902 builds. Don't chdir to the directory of the Emacs executable.
8903 This undoes code from 1997 which was justified by the need to
8904 "avoid conflicts when removing and renaming directories". But its
8905 downside was that every relative file name was being interpreted
8906 relative to the directory of the Emacs executable, which can never
8907 be TRT. In particular, it broke sys_access when called with
8908 relative file names.
8909 (sys_access): Map GetLastError to errno.
8911 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8913 * window.h (struct window): Change type of 'fringes_outside_margins'

8917 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8920 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8922 * gnutls.c (emacs_gnutls_handshake):
8923 Add QUIT to make the loop interruptible.
8925 2012-06-29 Glenn Morris <rgm@gnu.org>
8927 * charset.c (init_charset): Make lack of etc/charsets fatal.
8929 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8931 * editfns.c (region_limit): Fix type mismatch.
8933 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8935 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8936 undefined. Convert from xassert to eassert.
8937 * nsmenu.m: Convert from xassert to eassert.
8938 * nsterm.m: Likewise.
8940 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8942 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8944 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8946 Avoid integer overflow on scroll-left and scroll-right.
8947 * window.c (HSCROLL_MAX): New macro.
8948 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8949 overflow when requested scroll falls outside ptrdiff_t range.
8951 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8953 * window.h (struct window): Change type of 'hscroll',
8954 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8955 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8956 Adjust users accordingly.
8957 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8958 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8959 from EMACS_INT to ptrdiff_t.
8960 (make_window): Omit redundant initialization.
8962 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
8964 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
8966 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8968 * window.h (struct window): Change type of 'use_time' and
8969 'sequence_number' from Lisp_Object to int.

8978 enabled with --enable-checking=[all,glyphs] configure option.
8979 Fix GLYPH_DEBUG usage assuming that it may be undefined,
8980 adjust comments accordingly.

9031 avoid GCC warning about unused macro.
9033 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
9035 * alloc.c (allocate_string): Omit intervals initialization.
9036 * alloc.c (make_uninit_multibyte_string): Initialize intervals
9037 as in make_pure_string and make_pure_c_string.
9039 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9096 function is called with compile-time constant argument.
9097 * image.c (imagemagick_error): Convert to build_string.
9098 * w32proc.c (sys_spawnve): Likewise.

9101 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9103 Use sprintf return value instead of invoking strlen on result.
9104 In the old days this wasn't portable, since some sprintf
9105 implementations returned char *. But they died out years ago and
9106 Emacs already assumes sprintf returns int.
9107 Similarly for float_to_string.
9108 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9109 * ccl.c (ccl_driver):
9110 * character.c (string_escape_byte8):

9113 * print.c (print_object):
9114 * xdisp.c (message_dolog):
9115 * xfns.c (syms_of_xfns):
9116 Use sprintf or float_to_string result to avoid need to call strlen.
9117 * data.c (Fnumber_to_string):
9118 Use make_unibyte_string, since the string must be ASCII.
9119 * lisp.h, print.c (float_to_string): Now returns int length.
9120 * term.c (produce_glyphless_glyph):
9121 Use sprintf result rather than recomputing it.
9123 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9124 * Makefile.in (ALL_CFLAGS):
9125 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
9126 * gmalloc.c, regex.c: Include <config.h> unconditionally.
9128 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9130 * dispextern.h (xstrcasecmp): Define to library function
9131 strcasecmp if available.
9132 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.

9147 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
9149 * gtkutil.c (get_utf8_string): Remove redundant assignment.
9150 sprintf already null-terminates its output.
9152 * xfns.c (x_window): Remove redundant cast.
9154 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
9156 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
9157 `const char *' to `char *' to avoid compiler warning.
9159 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9161 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9162 instead of truncating it to 63 (admittedly a generous limit).
9164 * process.c: Fix spelling and caps in comments.
9166 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9168 * emacs.c (setpgrp): Remove definition, unused.

9214 * sound.c (sound_warning, parse_sound):
9215 Remove unnecessary forward decls.
9217 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9219 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
9220 * lisp.h (WAIT_READING_MAX): New macro.
9221 * dispnew.c (Fsleep_for, sit_for):
9222 * keyboard.c (kbd_buffer_get_event):
9223 * process.c (Faccept_process_output):
9224 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
9225 This improves on the previous patch, which introduced a bug
9226 when time_t is unsigned and as wide as intmax_t.
9227 See <http://bugs.gnu.org/9000#51>.
9229 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9231 * dispnew.c (sit_for, Fsleep_for):
9232 * keyboard.c (kbd_buffer_get_event):

9245 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
9246 Privately reported by Herbert J. Skuhra.
9247 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
9249 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
9250 not make_lisp_timeval, when the argument is of type EMACS_TIME.
9252 2012-06-23 Eli Zaretskii <eliz@gnu.org>
9254 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
9255 last argument of make_unibyte_string.
9257 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
9258 language ID in the event parameters.
9260 * w32term.c (w32_read_socket): Put the new keyboard codepage into
9261 event.code, not the obscure "character set ID".
9263 2012-06-23 Chong Yidong <cyd@gnu.org>
9265 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
9267 2012-06-23 Eli Zaretskii <eliz@gnu.org>

9284 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
9285 Privately reported by Herbert J. Skuhra.
9286 [__FreeBSD__]: Remove "*/" typo after "#include".

9290 Don't assume EMACS_TIME and struct timeval are the same type.
9292 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9294 Support higher-resolution time stamps (Bug#9000).
9295 The time stamps are only nanosecond-resolution at the C level,
9296 since that's the best that any real-world system supports now.
9297 But they are picosecond-resolution at the Lisp level, as that's
9298 easy, and leaves room for future OS improvements.
9300 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9303 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9304 Don't get current time unless it's needed.
9306 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9307 now provides it if it's absent.
9308 (start_atimer): Port to higher-res time stamps.
9309 Check for time stamp overflow. Don't get current time more
9310 often than is needed.
9312 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9313 Include systime.h, not time.h.
9314 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9316 * dired.c: Include stat-time.h.
9317 (Ffile-attributes): File times now have higher resolution.
9319 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9320 (struct image): Timestamp now has higher resolution.
9322 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9323 has at least microseconds now. All uses removed.
9324 (update_frame, update_single_window, update_window, update_frame_1)
9325 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9326 (duration_to_sec_usec): Remove; no longer needed.
9328 * editfns.c (time_overflow): Now extern.
9329 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
9330 (float-time, Fformat_time_string, Fcurrent_time_string)

9333 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9334 (decode_time_components, lisp_seconds_argument): New functions.
9335 (make_time): Now static.
9336 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9337 Report an error if the time is invalid, rather than having the caller
9340 * fileio.c: Include <stat-time.h>
9341 (Fcopy_file): Copy higher-resolution time stamps.
9342 Prefer to set the time stamp via a file descriptor if that works.
9343 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9344 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9345 (Fvisited_file_modtime, Fset_visited_file_modtime):
9346 Support higher-resolution time stamps.
9348 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9350 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9352 * image.c (prepare_image_for_display, clear_image_cache)
9353 (lookup_image): Port to higer-resolution time stamps.
9355 * keyboard.c (start_polling, bind_polling_period):
9356 Check for time stamp overflow.
9357 (read_char, kbd_buffer_get_event, timer_start_idle)
9358 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9359 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9360 Port to higher-resolution time stamps. Do not assume time_t is signed.
9361 (decode_timer): New function. Timers are now vectors of length 9,
9362 not 8, to accommodate the picosecond component.
9363 (timer_check_2): Use it.
9365 * nsterm.m (select_timeout, timeval_subtract): Remove.
9366 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9367 as they're a bit more accurate and handle overflow better.
9368 (ns_select): Change prototype to be compatible with pselect.
9369 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9370 * nsterm.h (ns_select): Adjust prototype.
9372 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9373 us-resolution time stamps.
9374 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9376 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9378 * lisp.h (time_overflow): New decl.
9379 (wait_reading_process_output): First arg is now intmax_t, not int,
9380 to accommodate larger waits.
9382 * process.h (struct Lisp_Process.read_output_delay):
9383 Now counts nanoseconds, not microseconds.
9384 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9386 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9387 (wait_reading_process_output):
9388 Port to ns-resolution time stamps.
9389 (Faccept_process_output, wait_reading_process_output):
9390 Check for time stamp overflow. Do not assume time_t is signed.
9391 (select_wrapper): Remove; we now use pselect.
9392 (Fprocess_attributes): Now generates ns-resolution time stamps.
9394 * sysdep.c: Include utimens.h. Don't include utime.h
9395 or worry about struct utimbuf; gnulib does that for us now.
9396 (gettimeofday): Remove; gnulib provides a substitute.
9397 (make_timeval): New function.
9398 (set_file_times): Now sets ns-resolution time stamps.
9399 New arg FD; all uses changed.
9400 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9401 (system_process_attributes):
9402 Now returns ns-resolution time stamp. All uses changed.
9403 Check for time stamp overflow.
9405 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9406 provides a substitute now.
9408 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9409 since it guarantees struct timespec.
9410 (EMACS_TIME): Now struct timespec, so that we can support
9411 ns-resolution time stamps.
9412 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9413 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9414 (EMACS_USECS): Remove.
9415 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9416 so multiply the arg by 1000 before storing it.
9417 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9419 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9420 Port to ns-resolution time stamps.
9421 (EMACS_TIME_NEG_P): Remove; replaced by....
9422 (EMACS_TIME_SIGN): New macro.
9423 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9424 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.

9426 (make_timeval, make_lisp_time, decode_time_components): New decls.
9427 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9428 that it mishandled time_t overflow. You can't compare by subtracting!
9429 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9430 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9432 * term.c: Include <sys/time.h>.
9433 (timeval_to_Time): New function, for proper overflow wraparound.

9438 (Fprimitive_undo): Use them when restoring time stamps.
9440 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9441 (w32_get_internal_run_time):
9442 Port to higher-resolution Emacs time stamps.
9443 (ltime): Now accepts single 64-bit integer, as that's more convenient
9446 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9448 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9449 for compatibility with pselect. Support ns-resolution time stamps.
9451 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9453 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9454 Check for time stamp overflow, and support ns-resolution time stamps.
9456 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9457 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9458 (timeval_subtract): Remove; no longer needed.
9459 (XTflash, XTring_bell, x_wait_for_event):
9460 Port to ns-resolution time stamps. Don't assume time_t is signed.
9462 2012-06-22 Chong Yidong <cyd@gnu.org>
9464 * xdisp.c (x_consider_frame_title): Revert last change.
9466 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9468 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9469 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9470 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9471 staticidx goes up to 1597 out of 1600 = 0x640.)
9473 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9475 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9476 Otherwise, the umask might be mistakenly 0 while handling input signals.
9478 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
9480 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

9497 (unwind_format_mode_line): Restore them.
9498 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9500 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9501 since tty frames can be explicitly named.
9502 (prepare_menu_bars): Likewise.
9504 * term.c (Ftty_top_frame): New function.
9506 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9508 Port byte-code-meter to modern targets.
9509 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9510 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9511 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9512 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
9513 (METER_1, METER_2): Simplify.
9515 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>

9519 2012-06-18 Martin Rudalics <rudalics@gmx.at>
9521 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9522 gets killed during executing of this function (Bug#11665).
9523 Try to always return Qt when the buffer has been actually killed.
9524 (Vkill_buffer_query_functions): In doc-string say that functions
9525 run by this hook should not change the current buffer.
9527 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9529 Fix recently-introduced process.c problems found by static checking.
9530 * process.c (write_queue_push, write_queue_pop, send_process):

9533 (send_process): Remove unused local.
9535 2012-06-17 Chong Yidong <cyd@gnu.org>

9538 frames that are not on top.
9540 2012-06-17 Troels Nielsen <bn.troels@gmail.com>

9745 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9746 Use an inline function on all platforms when using the union type,
9747 since this is simpler and 'static inline' can be used portably

9891 * doprnt.c (doprnt): Truncate multibyte char correctly.
9892 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9893 would mishandle a string argument "Xc" if X was a multibyte

9895 rather than including all of X.

9978 and 'double' in a couple of places.
9980 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9982 * xdisp.c (handle_stop): Detect whether we have overlay strings
9983 loaded by testing it->current.overlay_string_index to be
9984 non-negative, instead of checking whether n_overlay_strings is
9985 positive. (Bug#11587)

10002 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
10003 for the duration of call to load_charset, to avoid problems with
10004 callers of maybe_unify_char that access buffer text through C

10008 decrement the inhibition flag, instead of just setting or

10014 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.

10022 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
10024 Clean up __executable_start, monstartup when --enable-profiling.
10025 The following changes affect the code only when profiling.
10026 * dispnew.c (__executable_start): Rename from safe_bcopy.
10027 Define only on platforms that need it.
10028 * emacs.c: Include <sys/gmon.h> when profiling.
10029 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
10030 (__executable_start): Remove decl, since lisp.h does it now.
10031 (safe_bcopy): Remove decl; no longer has that name.
10032 (main): Coalesce #if into single bit of code, for simplicity.
10033 Cast pointers to uintptr_t, since standard libraries want integers
10035 * lisp.h (__executable_start): New decl.
10037 2012-05-31 Glenn Morris <rgm@gnu.org>
10039 * image.c (Fimagemagick_types): Doc fix.

10062 Do not create empty overlays with the evaporate property (Bug#9642).
10063 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
10064 Bug#9642, but explicitly check that the buffer the overlay would
10065 be moved to is live and rearrange lines to make sure that errors
10066 will not put the overlay in an inconsistent state.
10067 (Fdelete_overlay): Cosmetics.
10069 2012-05-28 Eli Zaretskii <eliz@gnu.org>
10071 * w32term.c (my_bring_window_to_top): New function.
10072 (x_raise_frame): Use handle returned by DeferWindowPos, which
10073 could be different from the original one.

10083 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
10085 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
10086 This avoids undefined behavior that might cause the eassert
10087 to not catch an out-of-range value.
10089 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
10091 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
10092 Update dependencies.
10094 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10096 * bidi.c (bidi_mirror_char): Fix last change.
10098 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

10101 when referring to sectname field in printf format.
10103 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
10105 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
10106 Only r_alloc_inhibit_buffer_relocation needed to be added;
10107 the others were already declared.
10109 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10110 before checking whether it's out of range. Put the check inside
10112 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
10114 2012-05-27 Ken Brown <kbrown@cornell.edu>
10116 * callproc.c (Fcall_process): Restore a line that was accidentally
10117 commented out in the 2011-02-13 change (bug#11547).
10119 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10121 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10122 defined on ralloc.c.
10124 * buffer.c [REL_ALLOC]: Remove prototypes of
10125 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10126 they are now on lisp.h.
10128 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10130 * search.c (search_buffer): Use it to inhibit relocation of buffer
10131 text while re_search_2 is doing its job, because re_search_2 is
10132 passed C pointers to buffer text. (Bug#11519)
10134 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10135 Update value to 24.
10137 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10138 state after an additional call to move_it_in_display_line_to, keep
10139 the values of it->max_ascent and it->max_descent found for the
10141 (pos_visible_p): Revert the comparison against bottom_y to what it
10142 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10145 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10147 Fix coding-related core dumps with gcc -ftrapv.
10148 The code was computing A - B, where A and B are pointers, and B is
10149 random garbage. This can lead to core dumps on platforms that
10150 have special pointer registers, and it also leads to core dumps on
10151 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10152 A - B only when B is initialized properly.
10153 * coding.c (coding_set_source, coding_set_destination): Return void.
10154 (coding_change_source, coding_change_destinations): New functions,
10155 with the old behaviors of coding_set_source and coding_set_destination.
10156 All callers that need an offset changed to use these new functions.
10158 2012-05-26 Glenn Morris <rgm@gnu.org>
10160 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
10162 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10164 Extend mouse support on W32 text-mode console.
10165 * xdisp.c (draw_row_with_mouse_face):
10166 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10168 * w32console.c: Include window.h.
10169 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10171 (initialize_w32_display): Initialize mouse-highlight data.
10173 * w32inevt.c: Include termchar.h and window.h.
10174 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10175 moves, call note_mouse_highlight. If help_echo changed, call
10176 gen_help_event to produce help-echo message in the echo area.
10177 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10180 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10182 * lread.c (read1): Simplify slightly to avoid an overflow warning
10183 with GCC 4.7.0 on x86-64.
10185 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10187 * bidi.c (bidi_mirror_char): Revert last change: an int is
10188 definitely wide enough here.
10190 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10192 Fix integer width and related bugs (Bug#9874).

10194 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
10195 (string_bytes, check_sblock, allocate_string_data):
10196 (compact_small_strings, Fmake_bool_vector, make_string)

10199 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
10200 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
10202 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10203 (allocate_pseudovector):
10204 Use int, not EMACS_INT, where int is wide enough.
10205 (inhibit_garbage_collection, Fgarbage_collect):
10206 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10207 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10208 int might not be wide enough.
10209 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10210 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10211 (bidi_at_paragraph_end, bidi_find_paragraph_start)

10215 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
10216 (Fkill_buffer, Fset_buffer_major_mode)
10217 (advance_to_char_boundary, Fbuffer_swap_text)

10224 (Foverlay_recenter, last_overlay_modification_hooks_used)
10225 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10226 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10227 (validate_region): Omit unnecessary test for b <= e,
10228 since that's guaranteed by the previous test.
10229 (adjust_overlays_for_delete): Avoid pos + length overflow.
10230 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10231 (report_overlay_modification):
10232 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10233 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10234 Omit pointer cast, which isn't needed anyway, and doesn't work
10235 after the EMACS_INT -> ptrdiff_t change.
10236 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10237 * buffer.h: Adjust decls to match defn changes elsewhere.
10238 (struct buffer_text, struct buffer):
10239 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10240 Use EMACS_INT, not int, where int might not be wide enough.
10241 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10242 not int, to avoid needless 32-bit limit on 64-bit hosts.
10243 (exec_byte_code): Use tighter memory-full test, one that checks
10244 for alloca overflow. Don't compute the address of the object just
10245 before an array, as that's not portable. Use EMACS_INT, not
10246 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10247 * callint.c (Fcall_interactively):
10248 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10249 * callproc.c (call_process_kill, Fcall_process):
10250 Don't assume pid_t fits into an Emacs fixnum.
10251 (call_process_cleanup, Fcall_process, child_setup):

10259 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10260 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10261 (casify_object): Avoid integer overflow when overallocating buffer.
10262 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10263 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10264 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10265 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10266 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10267 integers are now checked earlier. All uses replaced with XINT.
10269 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10270 For CCL_MapSingle, check that content and value are in int range.
10271 (ccl_driver, Fregister_code_conversion_map):
10272 Check that Vcode_version_map_vector is a vector.
10273 (resolve_symbol_ccl_program): Check that vector header is in range.
10274 Always copy the vector, so that we can check its contents reliably
10275 now rather than having to recheck each instruction as it's being
10276 executed. Check that vector words fit in 'int'.
10277 (ccl_get_compiled_code, Fregister_ccl_program)
10278 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10279 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10280 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10281 contents are in range.
10282 (Fccl_execute_on_string): Check that status is in range.
10283 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10284 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10285 Accept and return EMACS_INT, not int, because callers can pass values
10286 out of 'int' range.
10287 (c_string_width, strwidth, lisp_string_width, chars_in_text)
10288 (multibyte_chars_in_text, parse_str_as_multibyte)

10291 (string_escape_byte8, Fget_byte):
10292 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10293 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10294 avoid mishandling large integers.
10295 * character.h: Adjust decls to match defn changes elsewhere.
10296 * charset.c (load_charset_map_from_file, find_charsets_in_text)
10297 (Ffind_charset_region):
10298 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

10301 Don't assume fixnum fits in int.
10302 (load_charset_map_from_vector, Fmap_charset_chars):
10303 Remove now-unnecessary CHECK_NATNUMs.
10304 (Fdefine_charset_internal): Check ranges here, more carefully.
10305 Don't rely on undefined behavior with signed left shift overflow.
10306 Don't assume unsigned int fits into fixnum, or that fixnum fits
10307 into unsigned int. Don't require max_code to be a valid fixnum;
10308 that's not true for gb10830 4-byte on a 32-bit host. Allow
10309 invalid_code to be a cons, for the same reason. Require code_offset
10310 to be a character. Avoid int overflow if max_char is close
10312 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10313 this is intended anyway and avoids some undefined behavior.
10314 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10315 INDEX_TO_CODE_POINT, as that's what it expects.
10316 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10317 * charset.h (DECODE_CHAR): Return int, not unsigned;
10318 this is what was intended anyway, and it avoids undefined behavior.
10319 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10320 integer-overflow issues.
10321 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10322 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10323 where the argument is EMACS_INT, and this behavior is not intended.
10324 * chartab.c (Fmake_char_table, Fset_char_table_range)
10325 (uniprop_get_decoder, uniprop_get_encoder):
10326 Don't assume fixnum fits in int.
10327 * cmds.c (move_point): New function, that does the gist of
10328 Fforward_char and Fbackward_char, but does so while checking
10329 for integer overflow more accurately.
10330 (Fforward_char, Fbackward_char): Use it.
10331 (Fforward_line, Fend_of_line, internal_self_insert)
10332 (internal_self_insert):
10333 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10334 Fix a FIXME, by checking for integer overflow when calculating

10368 (consume_chars): Rewrite to not calculate an address outside buffer.
10369 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
10370 Don't access memory outside of the args array.
10371 (Fdefine_coding_system_internal): Check for charset-id overflow.
10372 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
10373 result of ENCODE_CHAR.
10374 * coding.h: Adjust decls to match defn changes elsewhere.
10375 (struct coding_system):
10376 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

10391 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10392 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
10393 Do not attempt to compute the address of the object just before a
10394 buffer; this is not portable.
10396 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11093 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
11095 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
11096 reference to image_cache->refcount.
11097 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
11099 2012-05-17 Juri Linkov <juri@jurta.org>
11101 * search.c (Fword_search_regexp, Fword_search_backward)
11102 (Fword_search_forward, Fword_search_backward_lax)
11103 (Fword_search_forward_lax): Move functions to isearch.el
11104 (bug#10145, bug#11381).
11106 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
11108 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
11110 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
11112 * lread.c (init_obarray): Declare Qt and Qnil as special.
11114 2012-05-14 Glenn Morris <rgm@gnu.org>
11116 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
11117 Put "libexec" before "bin", for the sake of init_callproc_1.
11119 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11121 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
11123 * unexaix.c: Port to more-recent AIX compilers.
11124 (report_error, report_error_1, make_hdr, copy_sym)
11125 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11126 Make arguments const char *, not char *, to avoid violations of C
11127 standard and to fix some AIX warnings reported by Gilles Pion.
11129 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11131 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11132 already have overlays loaded.
11133 (handle_single_display_spec): Before returning without displaying
11134 fringe bitmap, synchronize the bidi iterator with the main display
11135 iterator, by calling iterate_out_of_display_property.
11136 (iterate_out_of_display_property): Detect buffer iteration by
11137 testing that it->string is a Lisp string.
11138 (get_next_display_element): When the current object is exhausted,
11139 and there's something on it->stack, call set_iterator_to_next to
11140 proceed with what's on the stack, instead of returning zero.
11141 (set_iterator_to_next): If called at the end of a Lisp string,
11142 proceed to consider_string_end without incrementing string
11143 position. Don't increment display vector index past the end of
11144 the display vector. (Bug#11417)
11145 (pos_visible_p): Don't report a position visible when move_it_to
11146 stopped at the last line of window, which happens to be scanned
11147 backwards by the bidi iteration. (Bug#11464)
11149 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11151 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11152 and right-margin display specs even if the spec is invalid or we
11153 are on a TTY, and thus unable to display on the fringes.
11154 That's because the text with the property will not be displayed anyway,
11155 so we need to signal to the caller that this is a "replacing"
11156 display spec. This fixes display when the spec is invalid or we
11159 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11161 * unexaix.c (make_hdr): Fix typo in prototype.
11162 This bug broke the build on AIX. Problem reported by Gilles Pion.
11164 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
11166 * keyboard.c (kbd_buffer_get_event): Read special events also in
11167 batch mode. (Bug#11415)
11169 2012-05-12 Glenn Morris <rgm@gnu.org>
11171 * ns.mk: Update for ns_appbindir no longer having trailing "/".
11173 2012-05-12 Eli Zaretskii <eliz@gnu.org>
11175 * lisp.mk (lisp): Add newcomment.elc.
11177 2012-05-12 Glenn Morris <rgm@gnu.org>
11179 * Makefile.in (MKDIR_P): New, set by configure.
11180 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11182 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11184 Remove unused function hourglass_started.
11185 * dispextern.h (hourglass_started):
11186 * w32fns.c (hourglass_started):
11187 * xdisp.c (hourglass_started): Remove.
11189 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11191 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11192 Update dependencies.
11194 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11196 * xgselect.c (xg_select): Put maxfds+1 into a var.
11197 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11199 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11201 2012-05-10 Dave Abrahams <dave@boostpro.com>
11203 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11204 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11206 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11208 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11209 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11210 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11211 Initialize xd_registered_buses.
11213 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11215 Untag more efficiently if USE_LSB_TAG.
11216 This is based on a proposal by YAMAMOTO Mitsuharu in
11217 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11218 For an admittedly artificial (nth 8000 longlist) benchmark on
11219 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11220 Emacs's overall text size by 1%.
11221 * lisp.h (XUNTAG): New macro.
11222 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11223 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11224 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11225 * eval.c (Fautoload):
11226 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11227 * frame.h (XFRAME): Use XUNTAG.
11229 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11230 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11231 Remove unportable assumptions about print widths of types like
11233 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11234 intptr_t when converting between pointer and integer, to avoid GCC
11235 warnings about wrong width.
11237 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11239 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11240 stack for each reader_thread, instead of defaulting to 8MB
11241 determined by the linker. This avoids failures in creating
11242 subprocesses on Windows 7, see the discussion in this thread:
11243 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11245 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11247 Fix up display of the *Minibuf-0* buffer in the mini window.
11248 * keyboard.c (read_char): Don't clear the echo area if there's no
11250 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11251 contents of *Minibuf-0*) if there's no message displayed in its stead.
11253 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11255 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11258 2012-05-06 Chong Yidong <cyd@gnu.org>
11260 * lisp.mk (lisp): Update.
11262 2012-05-05 Jim Meyering <meyering@redhat.com>
11264 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11266 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11268 * data.c (PUT_ERROR): New macro.
11269 (syms_of_data): Use it. Add new error type `user-error'.
11270 * undo.c (user_error): New function.
11271 (Fprimitive_undo): Use it.
11272 * print.c (print_error_message): Adjust print style for `user-error'.
11273 * keyboard.c (user_error): New function.
11274 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11276 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11278 Do not limit current-time-string to years 1000..9999.
11279 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11280 (Fcurrent_time_string): Support any year that is supported by the
11281 underlying localtime representation. Don't use asctime, as it
11282 has undefined behavior for years outside the range -999..9999.
11284 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11286 Fix race conditions involving setenv, gmtime, localtime, asctime.
11287 Without this fix, interrupts could mess up code that uses these
11288 nonreentrant functions, since setting TZ invalidates existing
11289 tm_zone or tzname values, and since most of these functions return
11290 pointers to static storage.
11291 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11292 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11293 Grow the critical sections to include not just invoking
11294 localtime/gmtime, but also accessing these functions' results
11295 including their tm_zone values if any, and any related TZ setting.
11296 (format_time_string): Last arg is now struct tm *, not struct tm **,
11297 so that the struct tm is saved in the critical section.
11298 All callers changed. Simplify allocation of initial buffer, partly
11299 motivated by the fact that memory allocation needs to be outside
11300 the critical section.
11302 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11304 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11305 with RESET_INTERVAL.
11307 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11308 Remove duplicated buffer name initialization.
11310 2012-05-02 Jim Meyering <jim@meyering.net>
11312 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11314 * xfns.c (x_window): Use xstrdup (Bug#11375).
11316 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11318 * xdisp.c (pos_visible_p): If already at a newline from the
11319 display string before the 'while' loop, don't walk back the glyphs
11320 from it3.glyph_row. Solves assertion violation when the display
11321 string begins with a newline (egg.el). (Bug#11367)
11323 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11325 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11328 2012-05-01 Glenn Morris <rgm@gnu.org>
11330 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11331 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11332 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11333 All were removed before 23.1.
11335 * dispnew.c: Remove HAVE_LIBNCURSES test;
11336 it is always true on relevant platforms.
11338 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11339 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11341 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11343 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11345 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11346 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11349 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11351 Do not avoid creating empty evaporating overlays (Bug#9642).
11352 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11353 That is, do not delete an evaporating overlay if it becomes
11354 empty after its bounds are adjusted to fit within its buffer.
11355 This fix caused other problems, and I'm reverting it until we get
11356 to the bottom of them.
11358 2012-04-27 Chong Yidong <cyd@gnu.org>
11360 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11362 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11364 * xdisp.c (pos_visible_p): If the window start position is beyond
11365 ZV, start the display from buffer beginning. Prevents assertion
11366 violation in init_iterator when the minibuffer window is scrolled
11367 via the scroll bar.
11369 * window.c (window_scroll_pixel_based): Likewise.
11371 2012-04-27 Chong Yidong <cyd@gnu.org>
11373 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11375 2012-04-27 Glenn Morris <rgm@gnu.org>
11377 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11378 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11380 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11382 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11383 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11385 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11387 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11388 display element, check also the underlying string or buffer
11389 character. (Bug#11341)
11391 * w32menu.c: Include w32heap.h.
11392 (add_menu_item): If the call to AppendMenuW (via
11393 unicode_append_menu) fails, disable Unicode menus only if we are
11394 running on Windows 9X/Me.
11396 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11398 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11399 (xgetint): Add missing shift for LSB tags.
11401 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11403 * keyboard.c (read_char): Don't wipe echo area for select window
11404 events: These might get delayed via `mouse-autoselect-window'
11407 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11409 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11410 manipulation of :loaded-from data.
11412 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11414 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11415 now a cons (bug#11311).
11417 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11419 Do not create empty overlays with the evaporate property (Bug#9642).
11420 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11421 if it becomes empty after its bounds are adjusted to fit within
11422 its buffer. Without this fix, in a nonempty buffer (let ((o
11423 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11424 yields an empty overlay that has the evaporate property, which is
11425 not supposed to happen.
11427 Fix minor GTK3 problems found by static checking.
11428 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11429 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11430 (struct _EmacsFixedClass, emacs_fixed_get_type):
11431 Move decls here from emacsgtkfixed.h, since they needn't be public.
11432 (emacs_fixed_get_type): Now static.
11433 (emacs_fixed_class_init): Omit unused local.
11434 (emacs_fixed_child_type): Remove; unused.
11435 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11436 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11437 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11438 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11439 (EMACS_FIXED_GET_CLASS): Remove; unused.
11440 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11442 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11443 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11445 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11447 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11448 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11449 (__malloc_size_t, __malloc_ptrdiff_t):
11450 Remove. All uses removed, replaced by the definiens if needed,
11451 since we can assume C89 or better now.
11452 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

11460 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11461 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11462 Define using prototypes, not old style.
11463 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11464 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11465 (align): Don't assume that signed integer overflow wraps around.
11466 Omit unused local var.
11467 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
11468 (_free_internal_nolock, memalign, mallochook, reallochook):
11469 Omit no-longer-needed casts.
11470 (valloc): Use getpagesize, not __getpagesize.
11471 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11472 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11474 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11476 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11478 Move functions from C to Lisp. Make non-blocking method calls
11479 the default. Implement further D-Bus standard interfaces.
11481 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

11497 (xd_signature, xd_append_arg): Allow float for integer types.
11498 (xd_get_connection_references): New function.
11499 (xd_get_connection_address): Rename from xd_initialize.
11500 Return cached address.
11501 (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS.
11502 (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp

11540 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11542 * sysdep.c [__FreeBSD__]: Minor cleanups.
11543 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11544 Use Emacs indenting style more consistently. Avoid some casts.
11545 Use 'double' consistently rather than mixing 'float' and 'double'.

11563 * print.c (print_preprocess): Only check print_depth if print-circle
11565 (print_object): Check for cycles even when print-circle is nil and
11566 print-gensym is t, but only check print_depth if print-circle is nil.

11570 * process.c (wait_reading_process_output): If EIO occurs on a pty,
11571 set the status to "failed" and ensure that sentinel is run.
11573 2012-04-20 Glenn Morris <rgm@gnu.org>
11575 * process.c (Fset_process_inherit_coding_system_flag)
11576 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

11586 farther than the first row after the header line, if any.
11587 Don't consider the header-line row as "partially visible", even if
11588 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
11590 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

11604 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
11605 -Wunused-result, -Wunused-variable. This should go away once
11606 the Emacs and Gnulib regex code is merged.
11607 (xmalloc, xrealloc): Now static.
11609 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

11626 New extern decls, to avoid calling undeclared functions.
11627 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11628 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11629 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11630 (NEED_MEM_INSERT): New macro.
11631 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11632 Remove one incorrect comment and fix another.

11647 Remove decls. This fixes an "It stinks!".
11649 * alloc.c (which_symbols): Fix alignment issue / type clash.
11651 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11653 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
11654 (struct Lisp_Misc_Any): Likewise.
11655 (struct Lisp_Free): Likewise.

11667 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
11668 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11669 * s/netbsd.h, s/sol2-6.h:
11670 Remove definition of GC_MARK_STACK, since the default now works.
11671 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

11673 no longer the default.
11674 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11676 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

11681 2012-04-14 Eli Zaretskii <eliz@gnu.org>
11683 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
11684 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

11697 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11699 2012-04-11 Daniel Colascione <dancol@dancol.org>
11701 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11702 against is gone. It's better to use vfork now so that when Cygwin
11703 gains a new, working vfork, we use it automatically (bug#10398).
11705 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
11707 * window.c (save_window_save): Obey window-point-insertion-type.

11725 * w32.c (w32_delayed_load): Record the full path of the library
11726 being loaded (bug#10424).
11728 2012-04-09 Glenn Morris <rgm@gnu.org>
11730 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11731 not just in the obarray, before snarfing them. (Bug#11036)

11748 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11749 attempts per process (connection).
11751 2012-04-09 Chong Yidong <cyd@gnu.org>
11753 * eval.c (Fuser_variable_p, user_variable_p_eh)

11755 (Fdefvar): Caller changed.
11757 * callint.c (Finteractive, Fcall_interactively):
11758 * minibuf.c (Fread_variable): Callers changed.
11760 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11762 * xdisp.c (set_cursor_from_row): If the display string appears in
11763 the buffer at position that is closer to point than the position
11764 after the display string, display the cursor on the first glyph of
11765 the display string. Fixes cursor display when a 'display' text
11766 property immediately follows invisible text. (Bug#11094)
11768 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11770 composite.c: use 'double' consistently
11771 * composite.c (get_composition_id): Use 'double' consistently
11772 instead of converting 'float' to 'double' and vice versa; this is
11773 easier to understand and avoids a GCC warning.
11775 2012-04-09 Glenn Morris <rgm@gnu.org>
11777 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11778 preparation for dumping it with emacs. (Bug#4789)

11800 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11801 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11802 objects, as mark_maybe_pointer will catch them otherwise.

11821 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11822 [!WINDOWSNT]: New macros.
11823 (init_libxml2_functions, libxml2_loaded_p): New functions.
11824 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11825 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11826 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11827 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11829 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11830 Call init_libxml2_functions before calling libxml2 functions.
11831 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11833 * emacs.c: Don't include libxml/parser.h.

11839 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11841 * indent.c (Fvertical_motion): If there is a display string at
11842 point, use it.vpos to compute how many lines to backtrack after
11843 move_it_to point. (Bug#11133)
11845 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11847 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11848 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11849 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11850 macros related to unification of CJK characters. For the details,
11851 see the discussion following the message here:
11852 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11854 2012-04-04 Chong Yidong <cyd@gnu.org>

11868 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11870 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11871 position we get to after a call to move_it_to fails the
11872 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11873 only if we wind up in a string from display property. (Bug#11063)
11875 * window.c (Fdelete_other_windows_internal): Invalidate the row
11876 and column information about mouse highlight, so that redisplay
11877 restores it after reallocating the glyph matrices. (Bug#7464)
11879 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11880 string comes from a `display' text property, use the buffer
11881 position of that property as if we actually saw that position in
11883 (move_it_by_lines): Remove the assertion that
11884 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11885 violated when there's a before-string at the beginning of a line.
11888 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11890 * xdisp.c (append_space_for_newline): If the default face was

11893 extending the face to the end of the line.
11894 (display_line): Call extend_face_to_end_of_line when the default
11895 face was remapped. (Bug#11068)

11923 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
11925 2012-03-25 Kenichi Handa <handa@m17n.org>
11927 * dispextern.h (struct glyph): Change the bit length of
11928 glyphless.ch to 22 to make the member glyphless fit in 32 bits.

11943 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11945 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11946 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11947 when fetching a multibyte character consumes more bytes than
11948 CHAR_BYTES returns, due to unification of CJK characters in
11949 string_char. (Bug#11073)
11951 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11953 * process.c (wait_reading_process_output): Handle pty disconnect
11954 by refraining from sending oneself a SIGCHLD (bug#10933).
11956 2012-03-22 Chong Yidong <cyd@gnu.org>
11958 * dispextern.h (struct it): New member string_from_prefix_prop_p.

11985 2012-03-18 Eli Zaretskii <eliz@gnu.org>
11987 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
11988 that is not from display property, accept the row as a "cursor
11989 row" if one of the string's character has a non-nil `cursor'
11990 property. Fixes cursor positioning when there are newlines in
11991 overlay strings, e.g. in icomplete.el. (Bug#11035)
11993 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

12024 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
12027 2012-03-03 Glenn Morris <rgm@gnu.org>
12029 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
12031 2012-03-02 Eli Zaretskii <eliz@gnu.org>

12034 position past the first glyph_row that ends at ZV. (Bug#10902)
12035 (redisplay_window, next_element_from_string): Fix typos in
12037 (redisplay_window): Pass to move_it_vertically the margin in
12038 pixels, not in screen lines.

12042 * buffer.c (buffer-list-update-hook): Doc fix.
12044 2012-02-29 Eli Zaretskii <eliz@gnu.org>
12046 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
12047 push_it before setting up the iterator for the first overlay
12048 string, even if we have an empty string loaded.
12049 (next_overlay_string): If there's an empty string on the iterator
12050 stack, pop the stack. (Bug#10903)
12052 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
12054 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
12055 Suggested by Stefan Monnier in
12056 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
12057 * alloc.c (widen_to_Lisp_Object): New static function.
12058 (mark_memory): Also mark Lisp_Objects by fetching pointer words
12059 and widening them to Lisp_Objects. This would work even if
12060 USE_LSB_TAG is defined and wide integers are used, which might
12061 happen in a future version of Emacs.
12063 2012-02-25 Chong Yidong <cyd@gnu.org>
12065 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

12070 before saving to clipboard manager.
12072 2012-02-24 Chong Yidong <cyd@gnu.org>
12074 * keyboard.c (process_special_events): Handle all X selection
12075 requests in kbd_buffer, not just the next one (Bug#8869).
12077 2012-02-23 Chong Yidong <cyd@gnu.org>
12079 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
12080 call when setting menu-bar-lines and tool-bar-lines parameters.
12081 (unwind_create_frame_1): New helper function.
12083 * window.c (inhibit_window_configuration_change_hook): New var.

12102 when computing $valmask.
12104 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
12105 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12106 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12107 It's useless in that case, and it can cause problems on hosts
12108 that allocate halves of EMACS_INT values separately.
12109 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12110 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12111 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12112 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12113 it avoids undefined behavior on hosts where shifting right by more
12114 than the word width has undefined behavior.
12116 2012-02-19 Chong Yidong <cyd@gnu.org>
12118 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12119 (Funhandled_file_name_directory, Ffile_name_as_directory)
12120 (Fdirectory_file_name, Fexpand_file_name)
12121 (Fsubstitute_in_file_name): Protect against invalid file handler
12122 return values (Bug#10845).

12136 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
12138 2012-02-15 Chong Yidong <cyd@gnu.org>
12140 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
12141 marked as special. Also, starting docstrings with * is obsolete.

12156 2012-02-12 Chong Yidong <cyd@gnu.org>
12158 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
12159 as that creates a dangerous corner case.
12161 * window.c (Fdelete_window_internal): Invalidate the mouse
12162 highlight (Bug#9904).
12164 2012-02-12 Glenn Morris <rgm@gnu.org>

12169 * nsselect.m (Fx_own_selection_internal)
12170 (Fx_disown_selection_internal, Fx_selection_exists_p)
12171 (Fx_selection_owner_p, Fx_get_selection_internal):
12172 Sync docs and argument specs with the xselect.c versions.
12174 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

12194 2012-02-07 Chong Yidong <cyd@gnu.org>
12196 * buffer.c (Fbuffer_local_variables)
12197 (buffer_lisp_local_variables): Handle unbound vars correctly;
12198 don't let Qunbound leak into Lisp.
12200 2012-02-07 Glenn Morris <rgm@gnu.org>
12202 * image.c (Fimagemagick_types): Doc fix.
12204 * image.c (imagemagick-render-type): Change it from a lisp object
12205 to an integer. Move the doc here from the lisp manual.

12222 2012-02-04 Eli Zaretskii <eliz@gnu.org>
12224 * w32.c (get_emacs_configuration_options):
12225 Include --enable-checking, if specified, in the return value.

12235 before BEGV. (Bug#10696)
12237 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
12239 Handle overflow when computing char display width (Bug#9496).
12240 * character.c (char_width): Return EMACS_INT, not int.
12241 (char_width, c_string_width): Check for overflow when
12242 computing the width; this is possible now that individual
12243 characters can have unbounded width. Problem introduced
12244 by merge from Emacs 23 on 2012-01-19.

12268 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
12270 (x_produce_glyphs): If the component of a composition is a null

12275 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
12276 first 2 arguments are identical. This makes inserting large
12277 output from a subprocess an order of magnitude faster on
12278 MS-Windows, where all sbrk'ed memory is always contiguous.
12280 2012-01-31 Glenn Morris <rgm@gnu.org>

12377 * xdisp.c (rows_from_pos_range): Accept additional argument
12378 DISP_STRING, and accept any glyph in a row whose object is that
12379 string as eligible for mouse highlight. Fixes mouse highlight of
12380 display strings from overlays. (Bug#10464)
12382 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
12384 emacs: fix an auto-save permissions race condition (Bug#10400)

12731 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12732 verifies glyph row's hash code--we have just reallocated the

12897 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
12898 is set, removing the need for VIRT_ADDRESS_VARIES.
12899 (PURE_P): Use a more-efficient implementation that needs just one

12902 to 4 (xorl, subq, cmpq, setbe).
12903 * alloc.c (pure): Always extern now, since that's the

12914 (erase_phys_cursor, update_window_cursor, show_mouse_face)
12915 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
12916 behave as if the cursor position were at the window margin.
12918 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12919 and the cursor position is out of bounds, behave as if the cursor
12920 position were at the window margin. (Bug#10075)
12922 2011-11-18 Chong Yidong <cyd@gnu.org>
12924 * window.c (Fwindow_combination_limit): Make first argument

13393 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13395 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
13396 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
13397 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
13398 (Fmove_to_window_line): Doc fix.
13400 2011-10-27 Chong Yidong <cyd@gnu.org>
13402 * process.c (make_process): Set gnutls_state to NULL.
13404 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
13405 non-NULL, regardless of GNUTLS_INITSTAGE.
13406 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
13407 an error. Set process slots as soon as we allocate them.
13409 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
13411 2011-10-27 Chong Yidong <cyd@gnu.org>
13413 * gnutls.c (emacs_gnutls_deinit): New function.
13414 Deallocate credentials structures as well as calling gnutls_deinit.
13415 (Fgnutls_deinit, Fgnutls_boot): Use it.
13417 * process.c (make_process): Initialize GnuTLS credentials to NULL.
13418 (deactivate_process): Call emacs_gnutls_deinit.
13420 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
13422 * image.c (x_create_x_image_and_pixmap):
13423 * w32.c (sys_rename, w32_delayed_load):
13424 * w32font.c (fill_in_logfont):
13425 * w32reg.c (x_get_string_resource): Silence compiler warnings.
13427 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
13429 * w32fns.c (w32_default_color_map): New function,
13430 extracted from Fw32_default_color_map.
13431 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
13433 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
13435 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
13437 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
13439 * keyboard.c (test_undefined): New function (bug#9751).
13440 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
13442 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
13444 * sysdep.c (init_sys_modes): Fix the check for the controlling
13445 terminal (Bug#6649).
13447 2011-10-20 Eli Zaretskii <eliz@gnu.org>
13449 * dispextern.h (struct bidi_it): New member next_en_type.
13451 * bidi.c (bidi_line_init): Initialize the next_en_type member.
13452 (bidi_resolve_explicit_1): When next_en_pos is valid for the
13453 current character, check also for next_en_type being WEAK_EN.
13454 (bidi_resolve_weak): Don't enter the expensive loop if the current
13455 position is before next_en_pos. Record the bidi type of the first
13456 non-ET, non-BN character we find, in addition to its position.
13457 (bidi_level_of_next_char): Invalidate next_en_type when
13458 next_en_pos is over-stepped.
13460 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
13462 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
13463 * editfns.c: Rewrite current-time-zone so that it invokes
13464 the equivalent of (format-time-string "%Z") to get the time zone name.
13465 This fixes a bug when the time zone name contains characters that
13466 need converting from the system time locale to Emacs internal format.
13467 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13468 that patch fixed format-time-string to do the conversion, but
13469 I forgot to fix current-time-zone.
13470 (format_time_string): New function, containing most of
13471 what Fformat_time_string used to contain.
13472 (Fformat_time_string): Rewrite in terms of format_time_string.
13473 This doesn't change this function's behavior.
13474 (current-time-zone): Rewrite to use format_time_string.
13475 This fixes the bug reported by Michael Schierl in
13476 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13477 Jason Rumney's 2007-06-07 change worked around this bug, but
13479 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13481 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13483 * xdisp.c (start_display): If the character at POS is displayed
13484 via a display vector, reset IT->current.dpvec_index to zero.
13485 (try_window_reusing_current_matrix): If a line ends in a display
13486 vector or the next line starts in a display vector, continue
13487 redrawing the window even though the character position of
13488 start_row was reached.
13491 2011-10-18 Chong Yidong <cyd@gnu.org>
13493 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13494 with nobreak-char-display too.
13496 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13498 Fix part 3 of bug#9771.
13499 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13500 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13501 non-neutral characters if the current character is a paragraph
13502 separator (a.k.a. Newline). This avoids running the same
13503 expensive loop twice, once when we consume the preceding newline
13504 and the other time when the line actually needs to be displayed.
13505 Avoid the loop when we see neutrals on the base embedding level
13506 following a character whose directionality is the same as the
13507 paragraph's. This avoids running the expensive loop when a line
13508 ends in a long sequence of neutrals, like control characters.
13509 Add assertion against STRONG_AL type. Slightly rearrange code
13510 that determines the type of a neutral given the first non-neutral
13512 (bidi_level_of_next_char): Set next_en_pos to zero when
13513 invalidating its info.
13515 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13517 * xdisp.c (push_display_prop): Determine whether to record string
13518 or buffer position by IT->string, not by IT->method. Allow
13519 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13520 (move_it_vertically_backward): Don't look for character position
13521 immediately after the newline when in a continuation line.
13524 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13526 * window.c (coordinates_in_window): Rewrite and delabelize
13527 vertical border check. (Bug#5357) (Bug#9618)
13529 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13531 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13532 errors in XSetWindowBorder (bug#9310).
13534 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13536 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13537 avoid crash when xmalloc overrun checking is enabled.
13539 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13541 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13542 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13543 cursor motion with <left> and <right> arrow keys.
13545 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13546 some callers set that themselves.
13548 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13550 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13551 display string and the previous row comes from the same string and
13552 is empty. (Bug#9739) (Bug#9738)
13554 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13556 * doc.c (get_doc_string): Encode file name (bug#9735).
13558 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13560 * bidi.c (bidi_level_of_next_char):
13561 * xdisp.c (get_visually_first_element): Remove old incorrect
13562 comments regarding the Unicode Line Separator character.
13564 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13566 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13568 * alloc.c (Fgc_status): Do not access beyond zombies array
13569 boundary if nzombies > MAX_ZOMBIES.
13570 * alloc.c (dump_zombies): Add missing format specifier.
13572 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13574 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13575 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13577 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13578 Some packages use them to denote characters with modifiers.
13580 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13582 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13583 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13584 matching a pp-number. Rename parameter var to var1.
13586 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13588 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13590 2011-10-08 Glenn Morris <rgm@gnu.org>
13592 * callint.c (Fcall_interactively): Give a more explicit error for the
13593 'c' case with a non-character input. (Bug#8479)
13595 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13597 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13599 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13600 lines that are hscrolled on the left.
13602 * dispnew.c (buffer_posn_from_coords): Account for a possible
13603 presence of header-line. (Bug#4426)
13605 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13607 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13608 Don't advertise functionality which we discourage or doesn't work.
13610 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13612 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13613 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13614 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13615 this makes Emacs dump core during garbage collection on rare
13616 occasions. sizeof is obviously inferior to offsetof here, so
13617 stick with offsetof.
13618 (GC_POINTER_ALIGNMENT): New macro.
13619 (mark_memory): Omit 3rd (offset) arg; caller changed.
13620 Don't assume EMACS_INT alignment is the same as pointer alignment.
13622 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13624 * keyboard.c (read_key_sequence_remapped): New var.
13625 (read_key_sequence): Compute remapping in the right buffer.
13626 (command_loop_1): Use read_key_sequence's remapping directly.
13628 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13630 * dired.c (file_name_completion): Don't expand file name.
13631 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13632 before checking file name handler.
13634 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13635 they've been requested explicitly (bug#9591).
13637 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13639 * keymap.c (Fsingle_key_description): Use make_specified_string
13640 instead of build_string to build string from push_key_description.
13643 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13645 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13646 This fixes a Y2038 bug on 64-bit hosts.
13647 * buffer.c (reset_buffer):
13648 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13649 (Fclear_buffer_auto_save_failure):
13650 Use 0, not -1, to represent an unset failure time, since time_t
13651 might not be signed.
13653 Remove dependency on glibc malloc internals.
13654 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13655 Move back here from lisp.h, but with their new implementations.
13656 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13657 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13658 * charset.c (charset_table_init): New static var.
13659 (syms_of_charset): Use it instead of xmalloc. This removes a
13660 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13661 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13662 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13663 Move back to alloc.c.
13664 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13665 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13667 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13669 * nsterm.m (windowDidResize): Call x_set_window_size only when
13670 ns_in_resize is true. Otherwise set pixelwidth/height and
13671 call change_frame_size (Bug#9628).
13673 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13675 Port --enable-checking=all to Fedora 14 x86-64.
13676 * charset.c (syms_of_charset): Also account for glibc malloc's
13677 internal overhead when calculating the initial malloc maximum.
13679 Port --enable-checking=all to Fedora 14 x86.
13680 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13682 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13683 (overrun_check_realloc, overrun_check_free):
13684 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13685 That way, xmalloc returns a properly-aligned pointer even if
13686 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13687 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13688 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13689 into account when calculating the initial malloc maximum.
13690 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13691 Move here from alloc.c, so that charset.c can use it too.
13692 Properly align; the old code wasn't right for common 32-bit hosts
13693 when configured with --enable-checking=all.
13694 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13695 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13697 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13699 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13702 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13704 * xdisp.c (compute_display_string_end): If there's no display
13705 string at CHARPOS, return -1.
13707 * bidi.c (bidi_fetch_char): When compute_display_string_end
13708 returns a negative value, treat the character as a normal
13709 character not covered by a display string. (Bug#9624)
13711 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13713 * lread.c (Fread_from_string): Fix typo in docstring.
13715 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13717 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13718 newline, reseat the iterator instead of bidi-iterating there one
13719 character at a time. (Bug#9610)
13720 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13721 TO_CHARPOS if the bidi iterator is at base embedding level.
13723 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13725 * lread.c (readevalloop): Use correct code for NBSP.
13726 (read1): Likewise. (Bug#9608)
13728 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13730 * dbusbind.c (Fdbus_register_signal): When service is not
13731 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13733 2011-09-25 Glenn Morris <rgm@gnu.org>
13735 * buffer.c (truncate-lines): Doc fix.
13737 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13739 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13740 (Fset_window_next_buffers): Doc fix.
13742 2011-09-24 Glenn Morris <rgm@gnu.org>
13744 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13746 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13748 Fix minor problems found by static checking.
13749 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13750 * indent.c (Fvertical_motion): Fix == vs = typo.
13752 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13754 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13755 Default value is now t. Doc fix.
13757 * indent.c (Fvertical_motion): Compute and apply the overshoot
13758 logic when moving up, not only when moving down. Fix the
13759 confusing name and values of the it_overshoot_expected variable;
13760 logic changes accordingly. (Bug#9254) (Bug#9549)
13762 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13763 CHARPOS is covered by a display string which includes newlines.
13764 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13765 is covered by a display string with embedded newlines.
13767 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13769 * dbusbind.c (Fdbus_register_signal): Add match rule to
13770 Vdbus_registered_objects_table. (Bug#9581)
13771 (Fdbus_register_method, Vdbus_registered_objects_table):
13774 2011-09-24 Jim Meyering <meyering@redhat.com>
13776 do not ignore write error for any output size
13777 The previous change was incomplete.
13778 While it makes emacs --batch detect the vast majority of stdout
13779 write failures, errors were still ignored whenever the output size is
13780 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13781 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13782 && echo FAIL: ignored write error
13783 FAIL: ignored write error
13784 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13785 && echo FAIL: ignored write error
13786 FAIL: ignored write error
13787 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13789 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13791 * emacs.c (Fkill_emacs): In noninteractive mode exit
13792 non-successfully if a write error occurred on stdout. (Bug#9574)
13794 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13796 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13799 * dispextern.h (struct it): Update the comment documenting what
13802 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13804 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13805 a display string, extend search for cursor position to end of row.
13806 (find_row_edges): If the row ends in a newline from a display
13807 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13808 Handle the case of a display string with multiple newlines.
13809 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13810 non-empty line. Fixes confusing cursor motion with arrow keys at
13811 the beginning of a line that starts with whitespace.
13813 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13815 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13818 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13820 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13821 boolean (Bug#9154).
13823 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13825 * xdisp.c (display_line): Record maximum and minimum buffer
13826 positions even if no glyphs were produced (e.g., by a zero-width
13827 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13828 buffer positions that will be removed from the glyph row because
13830 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13831 column is beyond frame width: don't subtract 1 "pixel" when
13832 computing width of the stretch.
13833 (reseat_at_next_visible_line_start): Undo the change made on
13834 2011-09-17 that saved paragraph information and restored it after
13835 the call to `reseat'. (Bug#9545)
13837 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13839 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13840 and turn window cursor on if cleared (Bug#9415).
13842 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13844 * search.c (boyer_moore): Take unibyte characters from pattern
13845 literally. (Bug#9458)
13847 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13849 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13851 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13853 Fix minor problem found by static checking.
13854 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13855 initialized, to pacify gcc -Wuninitialized.
13857 * fileio.c: Report proper errno when syscall falls.
13858 (Finsert_file_contents): Save and restore errno,
13859 so that report_file_error outputs the correct diagnostic.
13860 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13862 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13864 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13866 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13868 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13869 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13871 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13873 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13874 about the current paragraph and restore it after the call to reseat.
13876 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13877 (bidi_find_paragraph_start): Search back for paragraph beginning
13878 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13879 (bidi_move_to_visually_next): Only trigger paragraph-related
13880 computations when the last character is a newline or at EOB, not
13881 just any NEUTRAL_B. (Bug#9470)
13883 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13884 truncated lines if point is covered by a display string. (Bug#9524)
13886 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13888 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13889 (cons_to_x_long): New function.
13890 (lisp_data_to_selection_data): Use it. Correct the test for
13891 short-versus-long data; it was negated. Break out of vector
13892 loop, for efficiency, when a long datum is discovered.
13894 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13896 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13898 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13900 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13901 GCC PR/17406) by declaring this function with external scope.
13903 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13905 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
13906 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
13908 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13910 * editfns.c (Fformat): Correctly handle text properties on "%%".
13912 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13914 * xterm.c (x_draw_composite_glyph_string_foreground):
13915 * w32term.c (x_draw_composite_glyph_string_foreground):
13916 * term.c (encode_terminal_code):
13917 * composite.c (composition_update_it, get_composition_id):
13918 * xdisp.c (get_next_display_element)
13919 (fill_composite_glyph_string): Add comments about special meaning
13920 of TAB characters in a composition.
13922 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13924 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13925 This occurs when processing a multibyte format.
13926 Problem reported by Wolfgang Jenker.
13928 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13930 * xdisp.c (try_cursor_movement): Only check for exact match if
13931 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13933 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13935 Remove unused external symbols.
13936 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13937 * xdisp.c (calc_pixel_width_or_height): Now static.
13938 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13939 * indent.c (check_display_width):
13940 * w32term.c: Fix comment to match code.
13941 * xterm.c, xterm.h (x_catching_errors): Remove.
13943 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13945 * xselect.c: Use signed conversions more consistently (Bug#9498).
13946 (selection_data_to_lisp_data): Assume incoming selection data are
13947 signed integers, not unsigned. This is to be consistent with
13948 outgoing selection data, which was modified to use signed integers
13949 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13950 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13951 expects long, not unsigned long.
13953 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13955 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13956 computation of loop end. Reported by Johan Bockgård
13959 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13961 * frame.c (Fother_visible_frames_p): Function deleted.
13963 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13965 * indent.c (compute_motion): Process display vector front to back
13966 rather than the other way around. (Bug#2496)
13968 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13970 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13972 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13974 * minibuf.c (Fread_from_minibuffer): Doc fix.
13976 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13978 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13979 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13981 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13983 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13984 value for non-existent files.
13986 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13988 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13989 set its "size" to -1. This will set the modtime_size field of
13990 the corresponding buffer to -1, which is what
13991 verify-visited-file-modtime expects for files that do not exist.
13994 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13996 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13998 * lisp.h: ... from here. push_key_description is no longer
13999 defined in keyboard.c, so its declaration should not be in
14000 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
14001 logically belongs with push_key_description.
14003 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
14005 * buffer.h: Include <sys/types.h> instead of <time.h>.
14006 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
14007 Problem reported by Herbert J. Skuhra.
14009 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
14011 * xml.c (parse_region): Make the parsing work for
14012 non-comment-starting XML files again (bug#9144).
14014 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
14016 * image.c (gif_load): Fix calculation of bottom and right corner.
14019 2011-09-10 Eli Zaretskii <eliz@gnu.org>
14021 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
14022 redisplay in small windows.
14024 2011-09-09 Eli Zaretskii <eliz@gnu.org>
14026 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
14028 2011-09-08 Martin Rudalics <rudalics@gmx.at>
14030 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
14031 Operate on live windows only.
14033 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
14035 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
14037 2011-09-07 Eli Zaretskii <eliz@gnu.org>
14039 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
14040 only under bidi iteration.
14042 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
14044 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
14046 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14048 isnan: Fix porting problem to Solaris 10 with bundled gcc.
14049 Without this fix, the command to link temacs failed due to an
14050 undefined symbol __builtin_isnan. This is because
14051 /usr/include/iso/math_c99.h #defines isnan(x) to
14052 __builtin_isnan(x), but the bundled gcc, which identifies itself
14053 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
14055 * floatfns.c (isnan): #undef, and then #define to a clone of
14057 (Fisnan): Always define, since it's always available now.
14058 (syms_of_floatfns): Always define isnan at the Lisp level.
14060 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14062 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
14064 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
14066 * fileio.c: Fix bugs with large file offsets (Bug#9428).
14067 The previous code assumed that file offsets (off_t values) fit in
14068 EMACS_INT variables, which is not true on typical 32-bit hosts.
14069 The code messed up by falsely reporting buffer overflow in cases
14070 such as (insert-file-contents "big" nil 1 2) into an empty buffer
14071 when "big" contains more than 2**29 bytes, even though this
14072 inserts just one byte and does not overflow the buffer.
14073 (Finsert_file_contents): Store file offsets as off_t
14074 values, not as EMACS_INT values. Check for overflow when
14075 converting between EMACS_INT and off_t. When checking for
14076 buffer overflow or for overlap, take the offsets into account.
14077 Don't use EMACS_INT for small values where int suffices.
14078 When checking for overlap, fix a typo: ZV was used where
14079 ZV_BYTE was intended.
14080 (Fwrite_region): Don't assume off_t fits into 'long'.
14081 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14083 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14085 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14087 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14089 sprintf-related integer and memory overflow issues (Bug#9412).
14091 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14092 (esprintf, exprintf, evxprintf): New functions.
14093 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14094 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14095 (modify_event_symbol): Do not assume that the length of
14096 name_alist_or_stem is safe to alloca and fits in int.
14097 (Fexecute_extended_command): Likewise for function name and binding.
14098 (Frecursion_depth): Wrap around reliably on integer overflow.
14099 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14100 since some callers pass EMACS_INT values.
14101 (Fsingle_key_description): Don't crash if symbol name contains more
14102 than MAX_ALLOCA bytes.
14103 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14104 (get_minibuffer): Arg is now EMACS_INT, not int.
14105 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14106 (esprintf, exprintf, evxprintf): New decls.
14107 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14109 * dbusbind.c (signature_cat): New function.
14110 (xd_signature, Fdbus_register_signal):
14111 Do not overrun buffer; instead, report string overflow.
14113 * dispnew.c (add_window_display_history): Don't overrun buffer.
14114 Truncate instead; this is OK since it's just a log.
14116 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14117 even if the time zone offset is outlandishly large.
14118 Don't mishandle offset == INT_MIN.
14120 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14121 when creating daemon; the previous buffer-overflow check was incorrect.
14123 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14124 which has the guts of the old verror function.
14126 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14127 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14129 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14130 (font_unparse_xlfd): Don't blindly alloca long strings.
14131 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14132 fits in int, when using sprintf. Use single snprintf to count
14133 length of string rather than counting it via multiple sprintfs;
14134 that's simpler and more reliable.
14135 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14136 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14137 sprintf, in case result does not fit in int.
14139 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14140 (fontset_from_font): Print it.
14142 * frame.c (tty_frame_count): Now printmax_t, not int.
14143 (make_terminal_frame, set_term_frame_name): Print it.
14144 (x_report_frame_params): In X, window IDs are unsigned long,
14145 not signed long, so print them as unsigned.
14146 (validate_x_resource_name): Check for implausibly long names,
14147 and don't assume name length fits in 'int'.
14148 (x_get_resource_string): Don't blindly alloca invocation name;
14149 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14152 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14153 (xg_check_special_colors, xg_set_geometry):
14154 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14156 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14157 Use esprintf, not sprintf, in case result does not fit in int.
14159 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14160 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14161 it as a large positive number.
14162 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14163 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14165 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14166 in case result does not fit in int.
14168 * print.c (float_to_string): Detect width overflow more reliably.
14169 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14170 buffer overrun. Don't assume list length fits in 'int'. Treat
14171 print length of 0 as 0, not as infinity; to be consistent with other
14172 uses of print length in this function. Don't overflow print length
14173 index. Don't assume hash table size fits in 'long', or that
14174 vectorlike size fits in 'unsigned long'.
14176 * process.c (make_process): Use printmax_t, not int, to format
14177 process-name gensyms.
14179 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14181 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14182 to avoid potential buffer overrun.
14184 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14185 if X resource line is longer than 512 bytes.
14187 * xfns.c (x_window): Make sprintf buffer a bit bigger
14188 to avoid potential buffer overrun.
14190 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14192 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14194 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14196 Integer overflow fixes for scrolling, etc.
14197 Without these, Emacs silently mishandles large integers sometimes.
14198 For example, "C-u 4294967297 M-x recenter" was treated as if
14199 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14201 * xdisp.c (try_window_id): Check Emacs fixnum range before
14202 converting to 'int'.
14204 * window.c (window_scroll_line_based, Frecenter):
14205 Check that an Emacs fixnum is in range before assigning it to 'int'.
14206 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14207 values converted from Emacs fixnums.
14208 (Frecenter): Don't wrap around a line count if it is out of 'int'
14209 range; instead, treat it as an extreme value.
14210 (Fset_window_configuration, compare_window_configurations):
14211 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14213 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14214 that can exceed INT_MAX. Check that EMACS_INT value is in range
14215 before assigning it to the (possibly-narrower) index.
14216 (match_limit): Don't assume that a fixnum can fit in 'int'.
14218 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14221 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14222 (Fvertical_motion): Don't wrap around LINES values that don't fit
14223 in 'int'. Instead, treat them as extreme values. This is good
14224 enough for windows, which can't have more than INT_MAX lines anyway.
14226 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14228 * Require libxml/parser.h to avoid compilation warning.
14230 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14232 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14233 since this reportedly can destroy thread storage.
14235 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14237 * syntax.c (find_defun_start): Update all cache variables if
14238 exiting early (Bug#9401).
14240 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14242 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14244 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14245 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14246 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14248 * term.c (tty_append_glyph): New function.
14249 (produce_stretch_glyph): Static function and its prototype deleted.
14251 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14254 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14256 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14257 when checking :margin (Bug#9390).
14258 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14259 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14260 so that the name doesn't mislead. All uses changed.
14262 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14264 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14267 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14269 * xdisp.c (move_it_to): Don't bail out early when reaching
14270 position beyond to_charpos, if we are scanning backwards.
14271 (move_it_vertically_backward): When DY == 0, make sure we get to
14272 the first character in the line after the newline.
14274 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14276 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14277 (ccl_driver): Do not generate an out-of-range pointer.
14278 (Fccl_execute_on_string): Remove unnecessary check for
14279 integer overflow, noted by Stefan Monnier in
14280 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14281 Remove a FIXME that didn't need fixing.
14282 Simplify the newly-introduced buffer reallocation code.
14284 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14286 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14288 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14290 Integer and memory overflow issues (Bug#9196).
14292 * doc.c (get_doc_string): Rework so that
14293 get_doc_string_buffer_size is the actual buffer size, rather than
14294 being 1 less than the actual buffer size; this makes xpalloc more
14297 * image.c (x_allocate_bitmap_record, cache_image):
14298 * xselect.c (Fx_register_dnd_atom):
14299 Simplify previous changes by using xpalloc.
14301 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,

14306 (charset_compare): Don't overflow if priorities differ greatly.
14307 (Fsort_charsets): Don't assume list length fits in int.
14308 Check for size-calculation overflow when allocating sort data.
14309 (syms_of_charset): Allocate an initial charset table that is
14310 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14312 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14314 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14315 The actual value is always <= INT_MAX, and leaving it unsigned made

14318 * dispextern.h (struct glyph_matrix.rows_allocated)
14319 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14320 with xpalloc. The values are still always <= INT_MAX.

14329 (set_cache_region, invalidate_region_cache)
14330 (revalidate_region_cache, know_region_cache, region_cache_forward)
14331 (region_cache_backward, pp_cache):
14332 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14333 so that ptrdiff_t * can be passed to xpalloc.
14334 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14335 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

14350 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14352 Don't update size of array until after memory allocation succeeds,
14353 because xmalloc/xrealloc may not return.
14354 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14355 now that we have proper integer overflow checking.
14356 (record_overlay_string, overlay_strings): Catch overflows when
14357 calculating size of overlay_str_buf.
14359 * callproc.c (Fcall_process): Check for size overflow when
14360 calculating size of args2.
14361 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14362 Normally we prefer signed values, but sticking with ptrdiff_t would
14363 require adding more-complicated checks.
14365 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14366 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14367 Redo buffer-overflow calculations to avoid integer overflow.
14368 Add a FIXME comment where memory seems to be over-allocated.
14370 * character.c (Fstring): Check for size-calculation overflow.
14372 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid

14405 Don't assume message length fits in int.
14406 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14408 * emacs.c (main): Do not reallocate argv, since there is a null at
14409 the end that can be overwritten, and this way there's no need to
14410 worry about size-calculation overflow.
14411 (sort_args): Check for size-calculation overflow.
14413 * eval.c (init_eval_once, grow_specpdl): Don't update size until
14415 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.

14419 Check for integer overflow.
14420 (x_set_alpha): Do not assume XINT fits in int.
14422 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
14423 This is for the members text_lines, text_cols, total_lines, total_cols,
14424 where the system imposes an 'int' limit.
14426 * fringe.c (Fdefine_fringe_bitmap):
14427 Don't update size until alloc works.

14432 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
14433 Check for size-calculation overflow.
14434 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
14435 do, as we prefer signed integers.
14436 (id_to_widget.max_size, id_to_widget.used)
14437 (xg_store_widget_in_map, xg_remove_widget_from_map)

14441 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
14442 * gtkutil.h: Change prototypes to match the above.
14444 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
14445 are duplicate now that they've been promoted to lisp.h.

14491 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
14492 for command line length. Do not attempt to address one before the
14493 beginning of an array, as that's not portable.
14495 * term.c (max_frame_lines): Remove; unused.

14523 Check for size calculation overflow.
14524 (cache_face): Treat size calculation overflows as if they were

14528 (Fx_change_window_property): Use ptrdiff_t, not int, to count
14529 sizes, since they can exceed INT_MAX in size. Check for size

14534 Don't update size until alloc done.
14536 * xrdb.c (get_environ_db): Don't assume path length fits in int,
14537 as sprintf is limited to int lengths.
14539 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
14540 (X_LONG_MIN): New macros.
14541 Use them to make the following changes clearer.
14542 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
14543 This change doesn't affect the value now, but it may help remind
14544 future maintainers not to raise the value too much later.
14545 (SELECTION_QUANTUM): Remove, replacing with ...
14546 (selection_quantum): ... new function, which avoids overflow.
14548 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14549 assumption that selection length fits in 'int'.

14566 Don't store size until memory allocation succeeds.
14567 (x_get_window_property): Plug memory leak on memory exhaustion.
14568 Don't double-block input; malloc is safe here. Don't assume 2**34
14569 - 4 fits in unsigned long. Add an xassert to check
14570 XGetWindowProperty overflow. Be more careful about overflow
14571 calculations, and distinguish size from memory overflow better.
14572 (receive_incremental_selection): When tracing, don't assume
14573 unsigned int is less than INT_MAX.
14574 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
14575 harmful) conversions of unsigned short to int.
14576 (lisp_data_to_selection_data): Don't assume that integers
14577 in the range -65535 through -1 fit in an X unsigned short.
14578 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14579 result parameters unless successful. Rely on cons_to_unsigned
14580 to report problems with elements; the old code wasn't right anyway.
14581 (x_check_property_data): Check for int overflow; we cannot use
14582 a wider type due to X limits.

14615 * lisp.h (hash_lookup, hash_put):
14616 * minibuf.c (Ftest_completion):
14617 Use ptrdiff_t for hash table indexes, not int (which is too
14618 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14619 32-bit --with-wide-int hosts).
14621 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14622 Add a FIXME comment about memory leaks.

14630 with outlandish widths.
14631 * character.h (sanitize_tab_width): Rename from sanitize_width,
14632 now that we have two such functions. All uses changed.

14653 exceed limits imposed by XClientMessageEvent, as well as the usual
14654 ptrdiff_t and size_t limits.
14656 * keyboard.c: Overflow, signedness and related fixes.
14657 (make_lispy_movement): Use same integer type in forward decl
14658 that is used in the definition.
14659 (read_key_sequence, keyremap_step):
14660 Change bufsize argument back to int, undoing my 2011-03-30 change.
14661 We prefer signed types, and int is wide enough here.
14662 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14663 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14664 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14665 length, not size_t. Use ptrdiff_t for index, not int.
14666 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14667 possibility of integer overflow.

14691 (lookup_image): Remove unnecessary tests.
14692 (xbm_image_p): Locals are now of int, not EMACS_INT,
14693 since parse_image_check makes sure they fit into int.
14694 (png_load, gif_load, svg_load_image):
14695 Prefer int to unsigned where either will do.
14696 (tiff_handler): New function, combining the cores of the
14697 old tiff_error_handler and tiff_warning_handler.
14698 This function is rewritten to use vsnprintf and thereby avoid
14699 stack buffer overflows. It uses only the features of vsnprintf
14700 that are common to both POSIX and native Microsoft.
14701 (tiff_error_handler, tiff_warning_handler): Use it.
14702 (tiff_load, gif_load, imagemagick_load_image):
14703 Don't assume :index value fits in 'int'.
14704 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
14705 (imagemagick_load_image): Check that crop parameters fit into
14706 the integer types that MagickCropImage accepts. Don't assume
14707 Vimagemagick_render_type has a nonnegative value. Don't assume
14708 size_t fits in 'long'.
14709 (gs_load): Use printmax_t to print the widest integers possible.

14723 (handle_single_display_spec): If the display spec is of the form
14724 `(space ...)', and specifies display in the text area, return 2
14726 (try_cursor_movement): Check for the need to scroll more
14727 accurately, and prefer exact match for point under bidi.
14728 Don't advance `row' beyond the last row of the window.

14746 buffers, return left-to-right.
14747 (set_cursor_from_row): Consider candidate row a win if its glyph
14748 represents a newline and point is on that newline. Fixes cursor
14749 positioning on the newline at EOL of R2L text within L2R
14750 paragraph, and vice versa.
14751 (try_cursor_movement): Check continued rows, in addition to
14752 continuation rows. Fixes unwarranted scroll when point enters a

14781 * xdisp.c (redisplay_window): When computing centering_position,
14782 account for the height of the header line. (Bug#8874)
14784 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14785 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14786 candidate is selected by the mouse, and that candidate has a
14787 composed character under the mouse.
14789 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14790 coordinates reported by pos-visible-in-window-p for a composed
14791 character in column zero.
14793 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

14800 consider it a hit if to_charpos is anywhere in the range of the
14801 composed buffer positions.
14803 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14805 * image.c (gif_load): Don't assume that each subimage has the same
14806 dimensions as the base image. Handle disposal method that is
14807 "undefined" by the gif spec (Bug#9335).
14809 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14811 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14816 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
14817 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14818 from an Org mode buffer to a Speedbar frame.
14820 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14821 a composition, take its buffer position from IT->cmp_it.charpos.
14822 Fixes cursor positioning at the beginning of a line that begins
14823 with a composed character.
14825 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14827 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14828 character bidirectional type, use STRONG_L instead. Fixes crashes
14829 in a buffer produced by `describe-categories'.
14831 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14832 members before the level stack, so they would be saved and
14833 restored when copying iterator state. Fixes incorrect reordering
14834 around TABs covered by display properties.
14836 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
14838 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

14924 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14925 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14926 the event loop (Bug#7276).
14928 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

14952 (Fnetwork_interface_list): Allocate in increments of bytes instead
14953 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14954 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14956 (struct ifflag_def): notrailers is smart on OSX.
14957 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14958 Get hardware address with getifaddrs if available.

14962 * xdisp.c (iterate_out_of_display_property): xassert that
14963 IT->position is set to within IT->object's boundaries. Break from

14966 Set IT->current to match the bidi iterator unconditionally.
14967 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14968 entry. Force push_it to save on the stack the current
14969 buffer/string position, to be restored by pop_it. Fix flags in
14970 the iterator structure wrt the object coming from a display
14971 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14972 properties. (Bug#9284)
14974 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14976 * fontset.c (fontset_get_font_group): Add proper type checks.

15015 longlines-mode. (Bug#9254)
15016 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
15017 word-wrap under bidirectional display. (Bug#9224)
15019 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
15020 is non-zero, even if the data buffer is NULL. Fixes a crash in
15021 vertical-motion with longlines-mode. (Bug#9254)
15023 2011-08-05 Eli Zaretskii <eliz@gnu.org>
15025 * bidi.c <bidi_cache_total_alloc>: Now static.

15031 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
15032 amount allocated this far in `bidi_cache_total_alloc'.
15033 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
15034 non-zero, only free the data buffer without restoring the cache
15035 contents. All callers changed.
15037 * dispextern.h (bidi_unshelve_cache): Update prototype.
15039 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

15100 DISP_PROP_P, and pass it to compute_display_string_pos.
15101 Only handle text covered by a display string if DISP_PROP_P is returned
15102 non-zero. All callers of bidi_fetch_char changed.

15196 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15198 * regex.c (re_iswctype): Convert return values to boolean.
15200 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15202 * xdisp.c (compute_display_string_pos): Don't use cached display
15203 string position if the buffer had its restriction changed.
15206 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15208 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15210 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15212 Integer signedness and overflow and related fixes. (Bug#9079)
15214 * bidi.c: Integer size and overflow fixes.
15215 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15216 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15217 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15218 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15219 (bidi_find_other_level_edge):
15220 Use ptrdiff_t instead of EMACS_INT where either will do.
15221 This works better on 32-bit hosts configured --with-wide-int.
15222 (bidi_cache_ensure_space): Check for size-calculation overflow.
15223 Use % rather than repeated addition, for better worst-case speed.
15224 Don't set bidi_cache_size until after xrealloc returns, because it
15226 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15227 (bidi_cache_ensure_space): Also check that the bidi cache size
15228 does not exceed that of the largest Lisp string or buffer. See Eli
15229 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15231 * alloc.c (__malloc_size_t): Remove.
15232 All uses replaced by size_t. See Andreas Schwab's note
15233 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15235 * image.c: Improve checking for integer overflow.
15236 (check_image_size): Assume that f is nonnull, since
15237 it is always nonnull in practice. This is one less thing to
15238 worry about when checking for integer overflow later.
15239 (x_check_image_size): New function, which checks for integer
15240 overflow issues inside X.
15241 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15242 This removes the need for a memory_full check.
15243 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15244 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15245 (xbm_read_bitmap_data): Change locals back to 'int', since
15246 their values must fit in 'int'.
15247 (xpm_load_image, png_load, tiff_load):
15248 Invoke x_create_x_image_and_pixmap earlier,
15249 to avoid much needless work if the image is too large.
15250 (tiff_load): Treat overly large images as if
15251 x_create_x_image_and_pixmap failed, not as malloc failures.
15252 (gs_load): Use x_check_image_size.
15254 * gtkutil.c: Omit integer casts.
15255 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15256 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15258 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15260 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15261 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15262 would wrongly return t on a 64-bit host.
15264 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15265 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15266 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15267 and therefore cause GCC to emit a bogus diagnostic in some cases.
15269 * image.c: Integer signedness and overflow and related fixes.
15270 This is not an exhaustive set of fixes, but it's time to
15271 record what I've got.
15272 (lookup_pixel_color, check_image_size): Remove redundant decls.
15273 (check_image_size): Don't assume that arbitrary EMACS_INT values
15274 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15275 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15276 (tiff_load, imagemagick_load_image):
15277 Check for overflow in size calculations.
15278 (x_create_x_image_and_pixmap): Remove unnecessary test for
15279 xmalloc returning NULL; that can't happen.
15280 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15281 (xpm_color_bucket): Use better integer hashing function.
15282 (xpm_cache_color): Don't possibly over-allocate memory.
15283 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15284 (gif_memory_source):
15285 Use ptrdiff_t, not int or size_t, to record sizes.
15286 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15287 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15288 either works, as we prefer signed integers.
15289 (tiff_read_from_memory, tiff_write_from_memory):
15290 Return tsize_t, not size_t, since that's what the TIFF API wants.
15291 (tiff_read_from_memory): Don't fail simply because the read would
15292 go past EOF; instead, return a short read.
15293 (tiff_load): Omit no-longer-needed casts.
15294 (Fimagemagick_types): Don't assume size fits into 'int'.
15296 Improve hashing quality when configured --with-wide-int.
15297 * fns.c (hash_string): New function, taken from sxhash_string.
15298 Do not discard information about ASCII character case; this
15299 discarding is no longer needed.
15300 (sxhash-string): Use it. Change sig to match it. Caller changed.
15301 * lisp.h: Declare it.
15302 * lread.c (hash_string): Remove, since we now use fns.c's version.
15303 The fns.c version returns a wider integer if --with-wide-int is
15304 specified, so this should help the quality of the hashing a bit.
15306 * emacs.c: Integer overflow minor fix.
15307 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15308 Define only if GNU_LINUX.
15309 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15311 * dispnew.c: Integer signedness and overflow fixes.
15312 Remove unnecessary forward decls, that were a maintenance hassle.
15313 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15315 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15316 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15317 (prepare_desired_row, line_draw_cost):
15318 Use int, not unsigned, where either works.
15319 (save_current_matrix, restore_current_matrix):
15320 Use ptrdiff_t, not size_t, where either works.
15321 (init_display): Check for overflow more accurately, and without
15322 relying on undefined behavior.
15324 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15325 Remove, replacing with the new symbols in lisp.h. All uses changed.
15326 * fileio.c (make_temp_name):
15327 * filelock.c (lock_file_1, lock_file):
15328 * xdisp.c (message_dolog):
15329 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15330 Use pMd etc. instead.
15331 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15332 replacing the pWIDE etc. symbols removed from editfns.c.
15334 * keyboard.h (num_input_events): Now uintmax_t.
15335 This is (very slightly) less likely to mess up due to wraparound.
15338 * buffer.c: Integer signedness fixes.
15339 (alloc_buffer_text, enlarge_buffer_text):
15340 Use ptrdiff_t rather than size_t when either will do, as we prefer
15343 * alloc.c: Integer signedness and overflow fixes.
15344 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15345 (__malloc_size_t): Default to size_t, not to int.
15346 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15347 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15348 Prefer ptrdiff_t to size_t when either would do, as we prefer
15350 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15351 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15352 Now const. Initialize with values that are in range even if char
15354 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15355 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15356 These functions do the right thing with sizes > 2**32.
15357 (check_depth): Now ptrdiff_t, not int.
15358 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15359 Adjust to new way of storing sizes. Check for size overflow bugs
15361 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15362 slightly wrong anyway, as it missed one instance of
15363 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15364 (refill_memory_reserve): Omit needless cast to size_t.
15365 (mark_object_loop_halt): Mark as externally visible.
15367 * xselect.c: Integer signedness and overflow fixes.
15368 (Fx_register_dnd_atom, x_handle_dnd_message):
15369 Use ptrdiff_t, not size_t, since we prefer signed.
15370 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15371 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15372 x_dnd_atoms_size and x_dnd_atoms_length.
15374 * doprnt.c: Prefer signed to unsigned when either works.
15376 * doprnt.c (doprnt):
15378 * xdisp.c (vmessage):
15379 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15380 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15381 prefer signed arithmetic to avoid comparison confusion.
15382 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15383 but is a bit tricky.
15385 Assume freestanding C89 headers, string.h, stdlib.h.
15386 * data.c, doprnt.c, floatfns.c, print.c:
15387 Include float.h unconditionally.
15388 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15389 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15390 * regex.c: Likewise for stddef.h, string.h.
15391 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15392 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15393 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15394 (STDC_HEADERS): Remove obsolete defines.
15395 * sysdep.c: Include limits.h unconditionally.
15397 Assume support for memcmp, memcpy, memmove, memset.
15398 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15399 * regex.c (memcmp, memcpy):
15400 Remove; we assume C89 now.
15402 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15403 (__malloc_safe_bcopy): Remove; no longer needed.
15405 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15406 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15407 well either way, and we prefer signed to unsigned.
15409 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15411 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15412 closes the connection while we're reading (bug#9182).
15414 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15416 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15417 are specified (Bug#9168).
15419 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15421 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15422 Found by GCC static checking and --with-wide-int on a 32-bit host.
15424 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15426 * xdisp.c (compute_display_string_pos): Fix logic of caching
15427 previous display string position. Initialize cached_prev_pos to
15428 -1. Fixes slow-down at the beginning of a buffer.
15430 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15432 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15433 for attrs[LFACE_FONTSET_INDEX].
15435 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15437 * xml.c (parse_region): Remove unused local
15438 that was recently introduced.
15440 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15442 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15443 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15445 * xdisp.c (move_it_in_display_line_to): Record the best matching
15446 position for TO_CHARPOS while scanning the line, and restore it on
15447 exit if none of the characters scanned was an exact match.
15448 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15449 when exact match is impossible due to invisible text, and the
15450 lines are truncated.
15452 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15454 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15457 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15459 Fix a significant slow-down of cursor motion with C-n, C-p,
15460 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15461 auto-repeat under bidi redisplay in fontified buffers.
15462 * xdisp.c (compute_stop_pos_backwards): New function.
15463 (next_element_from_buffer): Call compute_stop_pos_backwards to
15464 find a suitable prev_stop when we find ourselves before
15466 (reseat): Don't look for prev_stop, as that could mean a very long
15468 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15469 <cached_disp_overlay_modiff>: Cache for last found display string
15471 (compute_display_string_pos): Return the cached position if asked
15472 about the same buffer in the same area of character positions, and
15473 the buffer wasn't changed since the time the display string
15474 position was cached.
15476 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15478 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15479 is an integer, which is important for empty lines. (Bug#9149)
15481 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15483 * frame.c (Fmodify_frame_parameters): In tty case, update the
15484 default face if necessary (Bug#4238).
15486 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15488 * editfns.c (Fstring_to_char): No need to explain what a character
15489 is in the docstring (Bug#6576).
15491 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15493 * xml.c (parse_region): Make sure we always return a tree.
15495 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15497 * xml.c (parse_region): If a document contains only comments,
15500 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15502 * xml.c (make_dom): Return comments, too.
15504 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15507 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15508 and the surrounding thread.
15509 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15510 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15511 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15513 * s/openbsd.h (BROKEN_SIGIO): Define.
15514 * unexelf.c (unexec) [__OpenBSD__]:
15515 Don't update the .mdebug section of the Alpha COFF symbol table.
15517 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15519 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15522 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15524 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15525 This fixes some race conditions on the permissions of any newly
15528 * alloc.c (valid_pointer_p): Use pipe, not open.
15529 This fixes some permissions issues when debugging.
15531 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15532 If fchown fails to set both uid and gid, try to set just gid,
15533 as that is sometimes allowed. Adjust the file's mode to eliminate
15534 setuid or setgid bits that are inappropriate if fchown fails.
15536 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15538 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15539 to compare Lisp_Objects.
15540 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15541 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15542 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15544 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15546 * lread.c (read_integer): Unread even EOF character.
15547 (read1): Likewise. Properly record start position of symbol.
15549 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15550 symbol character follows.
15552 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15554 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15555 This works around a problem with the previous change to Fcopy_file.
15556 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15557 and without this change, GCC might complain about discarding
15558 fchown's return value.
15560 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15562 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15564 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15566 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15568 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15570 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15571 it's used from the C level.
15573 * process.c: Use the same condition for POLL_FOR_INPUT in both
15574 keyboard.c and process.c (bug#1858).
15576 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15578 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15579 (Fgnutls_boot): Use it.
15581 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15583 * doc.c (Fsubstitute_command_keys): Revert last change.
15585 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15587 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15588 quotes the next character, and doesn't affect other longer
15589 sequences (bug#8935).
15591 * lread.c (syms_of_lread): Clarify that is isn't only
15592 `eval-buffer' and `eval-defun' that's affected by
15593 `lexical-binding' (bug#8460).
15595 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15597 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15598 bidi redisplay when a line includes both an image and is truncated.
15600 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15602 Fix minor problems found by static checking.
15603 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15604 (elsz): Now a signed constant, not a size_t var. We prefer signed
15605 types to unsigned, to avoid integer comparison confusion. Without
15606 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15607 "cannot optimize loop, the loop counter may overflow", a symptom
15609 * indent.c (Fvertical_motion): Mark locals as initialized.
15610 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15612 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
15614 * search.c (Fre_search_backward): Mention `case-fold-search' in
15615 all the re_search_* functions (bug#8138).
15617 * keyboard.c (Fopen_dribble_file): Document when the file is
15620 2011-07-14 Eli Zaretskii <eliz@gnu.org>
15622 * bidi.c (bidi_dump_cached_states): Fix format of displaying
15625 Support bidi reordering of display and overlay strings.
15626 * xdisp.c (compute_display_string_pos)
15627 (compute_display_string_end): Accept additional argument STRING.
15628 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
15629 (reseat_to_string): Initialize bidi_it->string.s and
15630 bidi_it->string.schars.
15631 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
15632 NULL (avoids a crash in bidi_paragraph_init).
15633 Initialize itb.string.lstring.
15634 (init_iterator): Call bidi_init_it only of a valid
15635 buffer position was specified. Initialize paragraph_embedding to
15637 (reseat_to_string): Initialize the bidi iterator.
15638 (display_string): If we need to ignore text properties of

16134 (clone_per_buffer_values): Don't assume that

16136 This isn't true in general, and it's particularly not true
16137 if Emacs is configured with --with-wide-int.
16138 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
16139 New macros, used in the buffer.c change.

16175 Random fixes. E.g., (random) never returned negative values.
16176 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16177 subseconds part to the entropy, as that's a bit more random.
16178 Prefer signed to unsigned, since the signedness doesn't matter and
16179 in general we prefer signed. When given a limit, use a
16180 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16181 latter isn't right if USE_2_TAGS_FOR_INTS.
16182 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16183 not 0..VALMASK. Don't discard "excess" bits that random () returns.

16187 * textprop.c (text_property_stickiness):
16188 Obey Vtext_property_default_nonsticky.

16195 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
16196 This is more efficient than Ffile_directory_p and avoids a minor race.
16198 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16200 * buffer.c (Foverlay_put): Say what the return value is
16203 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16204 is a directory before asking whether to use the file name
16206 (barf_or_query_if_file_exists): Make the "File is a directory"
16207 error be more correct.
16209 * fns.c (Frequire): Remove the mention of the .gz files, since
16210 that's installation-specific, but keep the mention of
16211 `get-load-suffixes'.

16223 Qgnutls_bootprop_verify_error (which is no longer used).
16225 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16226 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16227 Also (re)move comments that are misplaced or no longer relevant.
16229 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16231 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

16290 (syms_of_keymap): Defsubr make-composed-keymap.
16291 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

16328 * eval.c (struct backtrace): Simplify and port the data structure.
16329 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16330 signed bit field, as this assumption is not portable and it makes
16331 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16332 "char debug_on_exit : 1" as this is not portable either; instead,
16333 use the portable "unsigned int debug_on_exit : 1". Remove unused
16334 member evalargs. Remove obsolete comments about cc bombing out.
16336 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

16515 Check for size-calculation overflow.
16516 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
16518 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
16520 * lread.c: Integer overflow fixes.
16521 (read_integer): Radix is now EMACS_INT, not int,
16522 to improve quality of diagnostics for out-of-range radices.
16523 Calculate buffer size correctly for out-of-range radices.
16524 (read1): Check for integer overflow in radices, and in
16525 read-circle numbers.
16526 (read_escape): Avoid int overflow.
16527 (Fload, openp, read_buffer_size, read1)
16528 (substitute_object_recurse, read_vector, read_list, map_obarray):
16529 Use ptrdiff_t, not int, for sizes.

16544 2011-06-22 Leo Liu <sdl.web@gmail.com>
16546 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
16547 Move to minibuffer.el.
16549 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16551 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16552 The following patches are for when GLYPH_DEBUG && !XASSERT.
16553 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16554 * dispnew.c (flush_stdout):
16555 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16556 Mark as externally visible.
16557 * dispnew.c (check_window_matrix_pointers): Now static.
16558 * dispnew.c (window_to_frame_vpos):
16559 * xfns.c (unwind_create_frame):
16560 * xterm.c (x_check_font): Remove unused local.
16561 * scroll.c (CHECK_BOUNDS):
16562 * xfaces.c (cache_fache): Rename local to avoid shadowing.
16563 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
16564 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
16565 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
16566 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16568 (debug_method_add): Use va_list and vsprintf rather than relying
16569 on undefined behavior with wrong number of arguments.
16570 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16571 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16572 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16573 since we're not interested in debugging glyphs with old libraries.
16574 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16575 GCC 4.6.0's static checking.
16577 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16579 Integer overflow and signedness fixes (Bug#8873).

16588 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
16589 (x_create_bitmap_from_xpm_data):
16590 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
16591 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
16593 * xfaces.c (load_pixmap):
16594 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
16595 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16596 (.bitmaps_last, struct x_output.icon_bitmap):
16597 Use ptrdiff_t, not int, for bitmap indexes.
16598 (x_allocate_bitmap_record): Check for size overflow.
16599 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16601 Use ptrdiff_t, not int, for overlay counts.
16602 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16603 * editfns.c (overlays_around, get_pos_property):
16604 * textprop.c (get_char_property_and_overlay):
16605 * xdisp.c (next_overlay_change, note_mouse_highlight):
16606 * xfaces.c (face_at_buffer_position):
16607 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16608 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16609 (Fnext_overlay_change, Fprevious_overlay_change)
16610 (mouse_face_overlay_overlaps, Foverlays_in):
16611 Use ptrdiff_t, not int, for sizes.
16612 (overlays_at, overlays_in): Check for size-calculation overflow.
16614 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16616 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16617 (x_session_initialize): Do not assume string length fits in int.
16619 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16620 This is unlikely, but can occur if DPI is outlandish.
16622 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16623 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16625 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16626 * xrdb.c (magic_file_p, search_magic_path):
16627 Omit last arg SUFFIX; it was always 0. All callers changed.
16628 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16630 * xfont.c (xfont_match): Avoid need for strlen.
16632 * xfns.c: Don't assume strlen fits in int.
16633 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16635 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16636 not unsigned long, as we prefer signed integers. All callers changed.
16637 Detect integer overflow in repeat count.
16638 (message_dolog): Don't assume print length fits in 39 bytes.
16639 (display_mode_element): Don't assume strlen fits in int.
16641 * termcap.c: Don't assume sizes fit in int and never overflow.
16642 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16643 (gobble_line): Check for size-calculation overflow.
16645 * minibuf.c (Fread_buffer):
16646 * lread.c (intern, intern_c_string):
16647 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16648 Don't assume string length fits in int.
16650 * keyboard.c (parse_tool_bar_item):
16651 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16653 * font.c: Don't assume string length fits in int.
16654 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16655 Use ptrdiff_t, not int.
16656 (font_intern_prop): Don't assume string length fits in int.
16657 Don't assume integer property fits in fixnum.
16658 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16660 * filelock.c: Fix some buffer overrun and integer overflow issues.
16661 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16662 Reformulate so as not to need the command string.
16663 Invoke gzip -cd rather than gunzip, as it's more portable.
16664 (lock_info_type, lock_file_1, lock_file):
16665 Don't assume pid_t and time_t fit in unsigned long.
16666 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16667 (current_lock_owner): Prefer signed type for sizes.
16668 Use memcpy, not strncpy, where memcpy is what is really wanted.
16669 Don't assume (via atoi) that time_t and pid_t fit in int.
16670 Check for time_t and/or pid_t out of range, e.g., via a network share.
16671 Don't alloca where an auto var works fine.
16673 * fileio.c: Fix some integer overflow issues.
16674 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16675 Don't assume string length fits in int.
16676 (directory_file_name): Don't assume string length fits in long.
16677 (make_temp_name): Don't assume pid fits in int, or that its print
16678 length is less than 20.
16680 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16682 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16684 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16686 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16687 We prefer signed integers, even for size calculations.
16689 * emacs.c: Don't assume string length fits in 'int'.
16690 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16691 (main): Don't invoke strlen when not needed.
16693 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16694 (XD_DEBUG_MESSAGE): Don't waste a byte.
16696 * callproc.c (getenv_internal_1, getenv_internal)
16697 (Fgetenv_internal):
16698 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16700 * lread.c (invalid_syntax): Omit length argument.
16701 All uses changed. This doesn't fix a bug, but it simplifies the
16702 code away from its former Hollerith-constant appearance, and it's
16703 one less 'int' to worry about when looking at integer-overflow issues.
16704 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16706 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16707 This didn't break anything, but it didn't help either.
16708 It's confusing to put a bogus integer in a place where the actual
16709 value does not matter.
16710 (LIST_END_P): Remove unused macro and its bogus comment.
16711 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16713 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16714 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16716 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16717 We prefer signed types, and the value cannot exceed the EMACS_INT
16718 range anyway (because otherwise the length would not be representable).
16719 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16720 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16721 This avoids a GCC warning when WIDE_EMACS_INT.
16723 * indent.c (sane_tab_width): New function.
16724 (current_column, scan_for_column, Findent_to, position_indentation)
16725 (compute_motion): Use it. This is just for clarity.
16726 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16728 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16730 * lisp.h (lint_assume): New macro.
16731 * composite.c (composition_gstring_put_cache):
16732 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16734 * editfns.c, insdel.c:
16735 Omit unnecessary forward decls, to simplify future changes.
16737 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16739 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16741 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16742 Use much-faster test for byte-length change.
16743 Don't assume string byte-length fits in 'int'.
16744 Check that character arg fits in 'int'.
16745 (mapcar1): Declare byte as byte, for clarity.
16747 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16749 * fns.c (concat): Catch string overflow earlier.
16750 Do not rely on integer wraparound.
16752 * dispextern.h (struct it.overlay_strings_charpos)
16753 (struct it.selective): Now EMACS_INT, not int.
16754 * xdisp.c (forward_to_next_line_start)
16755 (back_to_previous_visible_line_start)
16756 (reseat_at_next_visible_line_start, next_element_from_buffer):
16757 Don't arbitrarily truncate the value of 'selective' to int.
16759 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16761 * composite.c: Don't truncate sizes to 'int'.
16762 (composition_gstring_p, composition_reseat_it)
16763 (composition_adjust_point): Use EMACS_INT, not int.
16764 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16765 not EMACS_UINT, for indexes.
16767 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16769 * buffer.c: Include <verify.h>.
16770 (struct sortvec.priority, struct sortstr.priority):
16771 Now EMACS_INT, not int.
16772 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16773 (struct sortstr.size, record_overlay_string)
16774 (struct sortstrlist.size, struct sortlist.used):
16775 Don't truncate size to int.
16776 (record_overlay_string): Check for size-calculation overflow.
16777 (init_buffer_once): Check at compile-time, not run-time.
16779 2011-06-22 Jim Meyering <meyering@redhat.com>
16781 Don't leak an XBM-image-sized buffer
16782 * image.c (xbm_load): Free the image buffer after using it.
16784 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16787 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16788 that Sun C diagnosed.
16789 * fns.c (secure_hash): Fix pointer signedness issue.
16790 * intervals.c (static_offset_intervals): New function.
16791 (offset_intervals): Use it.
16793 2011-06-21 Leo Liu <sdl.web@gmail.com>
16796 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16799 * fns.c (secure_hash): Rename from crypto_hash_function and change
16800 the first arg to accept symbols.
16801 (Fsecure_hash): New primitive.
16802 (syms_of_fns): New symbols.
16804 2011-06-20 Deniz Dogan <deniz@dogan.se>
16806 * process.c (Fset_process_buffer): Clarify return value in
16809 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16811 * dispnew.c (add_window_display_history): Use BVAR.
16813 * xdisp.c (debug_method_add): Use BVAR.
16814 (check_window_end, dump_glyph_matrix, dump_glyph)
16815 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16817 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16820 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16821 check till after the cache is created in init_frame_faces.
16823 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16825 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16827 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16829 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16830 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16831 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16833 Improve buffer-overflow checking (Bug#8873).
16834 * fileio.c (Finsert_file_contents):
16835 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16836 Remove the old (too-loose) buffer overflow checks.
16837 They weren't needed, since make_gap checks for buffer overflow.
16838 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16839 The old code merely checked for Emacs fixnum overflow, and relied
16840 on undefined (wraparound) behavior. The new code avoids undefined
16841 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16843 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16844 Tune. Don't use wider integers than needed. Don't use alloca.
16845 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16847 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16849 * insdel.c, lisp.h (buffer_overflow): New function.
16850 (insert_from_buffer_1, replace_range, replace_range_2):
16851 * insdel.c (make_gap_larger):
16852 * editfns.c (Finsert_char):
16853 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16855 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16857 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16859 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16861 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16862 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16864 * fileio.c: Don't assume EMACS_INT fits in off_t.
16865 (emacs_lseek): New static function.
16866 (Finsert_file_contents, Fwrite_region): Use it.
16867 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16869 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16871 * fns.c: Don't overflow int when computing a list length.
16872 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16873 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16874 truncation on 64-bit hosts. Check for QUIT every
16875 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16876 faster and is responsive enough.
16877 (Flength): Report an error instead of overflowing an integer.
16878 (Fsafe_length): Return a float if the value is not representable
16879 as a fixnum. This shouldn't happen except in contrived situations.
16880 (Fnthcdr, Fsort): Don't assume list length fits in int.
16881 (Fcopy_sequence): Don't assume vector length fits in int.
16883 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16884 (header_size, word_size): New constants.
16885 (allocate_vectorlike): Don't check size overflow here.
16886 (allocate_vector): Check it here instead, since this is the only
16887 caller of allocate_vectorlike that could cause overflow.
16888 Check that the new vector's length is representable as a fixnum.
16890 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16891 The previous code was bogus. For example, next_almost_prime (32)
16892 returned 39, which is undesirable as it is a multiple of 3; and
16893 next_almost_prime (24) returned 25, which is a multiple of 5 so
16894 why was the code bothering to check for multiples of 7?
16896 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16898 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16900 Variadic C functions now count arguments with ptrdiff_t.
16901 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16902 Back then I didn't know that the Emacs coding style prefers signed int.
16903 Also, in the meantime I found a few more instances where arguments
16904 were being counted with int, which may truncate counts on 64-bit
16905 machines, or EMACS_INT, which may be unnecessarily wide.
16906 * lisp.h (struct Lisp_Subr.function.aMANY)
16907 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16908 Arg counts are now ptrdiff_t, not size_t.
16909 All variadic functions and their callers changed accordingly.
16910 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16911 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16912 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16913 * callint.c (Fcall_interactively): Check arg count for overflow,
16914 to avoid potential buffer overrun. Use signed char, not 'int',
16915 for 'varies' array, so that we needn't bother to check its size
16916 calculation for overflow.
16917 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16918 * eval.c (apply_lambda):
16919 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16920 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16921 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16923 * callint.c (Fcall_interactively): Don't use index var as event count.
16925 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16926 * mem-limits.h (SIZE): Remove; no longer used.
16928 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16930 Remove unnecessary casts.
16931 * xterm.c (x_term_init):
16932 * xfns.c (x_set_border_pixel):
16933 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16934 These aren't needed now that we assume ANSI C.
16936 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16937 It's more likely to cause problems (due to unsigned overflow)
16940 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16942 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16944 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16946 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16948 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16950 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16952 GLYPH_CODE_FACE returns EMACS_INT, not int.
16953 * dispextern.h (merge_faces):
16954 * xfaces.c (merge_faces):
16955 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16956 Don't assume EMACS_INT fits in int.
16958 * character.h (CHAR_VALID_P): Remove unused parameter.
16959 * fontset.c, lisp.h, xdisp.c: All uses changed.
16961 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16963 * fns.c (concat): Minor tuning based on overflow analysis.
16964 This doesn't fix any bugs. Use int to hold character, instead
16965 of constantly refetching from Emacs object. Use XFASTINT, not
16966 XINT, for value known to be a character. Don't bother comparing
16967 a single byte to 0400, as it's always less.
16969 * floatfns.c (Fexpt):
16970 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16972 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16975 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16977 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16978 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16979 incorrectly succeed when S was a string, because 4294967386 was
16980 truncated before it was used.
16982 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16983 Otherwise, an out-of-range integer could cause undefined behavior
16986 * composite.c: Use int, not EMACS_INT, for characters.
16987 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16988 EMACS_INT, for values that are known to be in character range.
16989 This doesn't fix any bugs but is the usual style inside Emacs and
16990 may generate better code on 32-bit machines.
16992 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16993 This is for reasons similar to the recent CHAR_STRING fix.
16994 * charset.c (Fencode_char): Check that character arg is actually
16995 a character. Pass an int to ENCODE_CHAR.
16996 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16997 wider than 'int', as a compile-time check to prevent future regressions
17000 * character.c (char_string): Remove unnecessary casts.
17002 Make sure a 64-bit char is never passed to CHAR_STRING.
17003 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
17004 by silently ignoring the top 32 bits, allowing some values
17005 that were far too large to be valid characters.
17006 * character.h: Include <verify.h>.
17007 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
17008 arguments are no wider than unsigned, as a compile-time check
17009 to prevent future regressions in this area.
17011 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
17012 (Fsubst_char_in_region):
17014 * xdisp.c (decode_mode_spec_coding):
17015 Adjust to CHAR_STRING's new requirement.
17016 * editfns.c (Finsert_char, Fsubst_char_in_region):
17017 * fns.c (concat): Check that character args are actually
17018 characters. Without this test, these functions did the wrong
17019 thing with wildly out-of-range values on 64-bit hosts.
17021 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
17022 These casts should not be needed on 32-bit hosts, either.
17023 * keyboard.c (read_char):
17024 * lread.c (Fload): Remove casts to unsigned.
17026 * lisp.h (UNSIGNED_CMP): New macro.
17027 This fixes comparison bugs on 64-bit hosts.
17028 (ASCII_CHAR_P): Use it.
17029 * casefiddle.c (casify_object):
17030 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
17031 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
17032 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
17033 * dispextern.h (FACE_FROM_ID):
17034 * keyboard.c (read_char): Use UNSIGNED_CMP.
17036 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
17037 not to EMACS_INT, to avoid GCC warning.
17039 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
17041 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
17042 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
17043 isn't needed on 32-bit machines.
17045 * buffer.c (Fgenerate_new_buffer_name):
17046 Use EMACS_INT for count, not int.
17047 (advance_to_char_boundary): Return EMACS_INT, not int.
17049 * data.c (Qcompiled_function): Now static.
17051 * window.c (window_body_lines): Now static.
17053 * image.c (gif_load): Rename local to avoid shadowing.
17055 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
17056 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
17057 * alloc.c (make_save_value): Integer argument is now of type
17058 ptrdiff_t, not int.
17059 (mark_object): Use ptrdiff_t, not int.
17060 * lisp.h (pD): New macro.
17061 * print.c (print_object): Use it.
17063 * alloc.c: Use EMACS_INT, not int, to count objects.
17064 (total_conses, total_markers, total_symbols, total_vector_size)
17065 (total_free_conses, total_free_markers, total_free_symbols)
17066 (total_free_floats, total_floats, total_free_intervals)
17067 (total_intervals, total_strings, total_free_strings):
17068 Now EMACS_INT, not int. All uses changed.
17069 (Fgarbage_collect): Compute overall total using a double, so that
17070 integer overflow is less likely to be a problem. Check for overflow
17071 when converting back to an integer.
17072 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
17073 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
17074 These were 'int' variables that could overflow on 64-bit hosts;
17075 they were never used, so remove them instead of repairing them.
17076 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
17077 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
17078 Previously, this ceilinged at INT_MAX, but that doesn't work on
17080 (allocate_pseudovector): Don't use EMACS_INT when int would do.
17082 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
17083 (allocate_vectorlike): Check for ptrdiff_t overflow.
17084 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17085 when a (possibly-narrower) signed value would do just as well.
17086 We prefer using signed arithmetic, to avoid comparison confusion.
17088 * alloc.c: Catch some string size overflows that we were missing.
17089 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17090 for convenience in STRING_BYTES_MAX.
17091 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17092 The definition here is exact; the one in lisp.h was approximate.
17093 (allocate_string_data): Check for string overflow. This catches
17094 some instances we weren't catching before. Also, it catches
17095 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17096 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17097 and ptrdiff_t and EMACS_INT are both 64 bits.
17099 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17100 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
17101 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
17103 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
17105 * alloc.c (Fmake_string): Check for out-of-range init.
17107 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
17109 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
17111 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
17113 * xfns.c (x_set_scroll_bar_default_width): Remove argument to

17116 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
17117 (int_gtk_range_get_value): Move to the scroll bar part of the file.
17118 (style_changed_cb): Call update_theme_scrollbar_width and call
17119 x_set_scroll_bar_default_width and xg_frame_set_char_size for
17120 all frames (Bug#8505).
17121 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).

17124 and height if HAVE_GTK3 (Bug#8505).
17125 (scroll_bar_width_for_theme): New variable.
17126 (update_theme_scrollbar_width): New function.
17127 (xg_get_default_scrollbar_width): Move code to
17128 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

17131 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
17133 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
17135 2011-06-12 Martin Rudalics <rudalics@gmx.at>
17137 * frame.c (make_frame): Call other_buffer_safely instead of
17140 * window.c (temp_output_buffer_show): Call display_buffer with
17141 second argument Vtemp_buffer_show_specifiers and reset latter
17142 immediately after the call.
17143 (Vtemp_buffer_show_specifiers): New variable.
17144 (auto_window_vscroll_p, next_screen_context_lines)
17145 (Vscroll_preserve_screen_position): Remove leading asterisks from

17696 (display_prop_intangible_p): Reimplement to call
17697 handle_display_spec instead of single_display_spec_intangible_p.

17709 value of a `display' property is a "replacing spec".
17710 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17711 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

17741 * gnutls.c: Use Emacs's memory allocators.
17742 Without this change, the gnutls library would invoke malloc etc.
17743 directly, which causes problems on non-SYNC_INPUT hosts, and which
17744 runs afoul of improving memory_full behavior. (Bug#8761)
17745 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17746 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17747 xfree instead of the default malloc, realloc, free.
17748 (Fgnutls_boot): No need to check for memory allocation failure,
17749 since xmalloc does that for us.

17778 need to be updated by these changes.
17779 * fns.c (make_hash_table, maybe_resize_hash_table):
17780 Check for integer overflow with large hash tables.
17781 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17782 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17783 (SXHASH_REDUCE): New macro.
17784 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17785 Use it instead of discarding useful hash info with large hash values.
17786 (sxhash_float): New function.
17787 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17788 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17789 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17790 Rewrite to use FIXNUM_BITS, as this simplifies things.
17791 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17792 Adjust signatures to match updated version of code.
17793 (consing_since_gc): Now EMACS_INT, since a single hash table can
17794 use more than INT_MAX bytes.

17817 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17819 Don't force ./temacs to start in terminal mode.
17821 * frame.c (make_initial_frame): Initialize faces in all cases, not
17822 only when CANNOT_DUMP is defined.
17823 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
17825 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17827 * dispnew.c (add_window_display_history): Use const for the string
17828 pointer. Remove declaration, not needed.
17830 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17832 Use 'inline', not 'INLINE'.
17833 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
17834 * alloc.c, fontset.c (INLINE): Remove.
17835 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
17836 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
17837 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
17838 * gmalloc.c (register_heapinfo): Use inline unconditionally.
17839 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
17841 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
17843 Make it possible to run ./temacs.
17845 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17846 syms_of_callproc does the same thing. Remove test for
17847 "initialized", do it in the caller.
17848 * emacs.c (main): Avoid calling set_initial_environment when dumping.
17850 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
17852 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
17853 (read_minibuf): Use get_minibuffer.
17854 (syms_of_minibuf): Use DEFSYM.
17855 (Qmetadata): New var.
17856 * data.c (Qbuffer): Don't make it static.
17857 (syms_of_data): Use DEFSYM.
17859 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
17861 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
17862 (CCL_CODE_MIN): New macro.
17864 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
17866 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
17868 * eval.c (Qdebug): Now static.
17869 * lisp.h (Qdebug): Remove decl. This reverts a part of the
17870 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
17871 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
17873 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17875 * image.c: Various fixes to ImageMagick code comments.
17876 (Fimagemagick_types): Doc fix.
17878 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
17880 Minor fixes prompted by GCC 4.6.0 warnings.
17882 * xselect.c (converted_selections, conversion_fail_tag): Now static.
17884 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
17885 (x_clipboard_manager_save_all): Move extern decl to ...
17886 * xterm.h: ... here, so that it can be checked for consistency.
17888 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
17890 * xselect.c (x_clipboard_manager_save_frame)
17891 (x_clipboard_manager_save_all): New functions.
17892 (Fx_clipboard_manager_save): Lisp function deleted.
17894 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
17895 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
17897 * xterm.h: Update prototype.
17899 2011-05-28 William Xu <william.xwl@gmail.com>
17901 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
17902 exiting (Bug#8239).
17904 2011-05-28 Jim Meyering <meyering@redhat.com>
17906 Avoid a sign-extension bug in crypto_hash_function.
17907 * fns.c (to_uchar): Define.
17908 (crypto_hash_function): Use it to convert some newly-signed
17909 variables to unsigned, to avoid sign-extension bugs. For example,
17910 without this change, (md5 "truc") would evaluate to
17911 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17912 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17913 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17915 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17917 Integer overflow fixes.
17919 * dbusbind.c: Serial number integer overflow fixes.
17920 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17921 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17922 to hold a serial number that is too large for a fixnum.
17923 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17924 Check for serial numbers out of range. Decode any serial number
17925 that was so large that it became a float. (Bug#8722)
17927 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17928 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17929 Use XFASTINT rather than XUINT when numbers are nonnegative.
17930 (xd_append_arg, Fdbus_method_return_internal):
17931 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17932 arguments, check that Lisp number is nonnegative, rather than
17933 silently wrapping negative numbers around. (Bug#8722)
17934 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17937 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17939 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17941 ccl: Add integer overflow checks.
17942 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17943 (IN_INT_RANGE): New macros.
17944 (ccl_driver): Use them to check for integer overflow when
17945 decoding a CCL program. Many of the new checks are whether XINT (x)
17946 fits in int; it doesn't always, on 64-bit hosts. The new version
17947 doesn't catch all possible integer overflows, but it's an
17948 improvement. (Bug#8719)
17950 * alloc.c (make_event_array): Use XINT, not XUINT.
17951 There's no need for unsigned here.
17953 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17954 This follows up to the 2011-05-06 change that substituted uintptr_t
17955 for EMACS_INT. This case wasn't caught back then.
17957 Rework Fformat to avoid integer overflow issues.
17958 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17959 now (part of C89). Include <verify.h>.
17960 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17961 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17962 (Fformat): Avoid the prepass trying to compute sizes; it was only
17963 approximate and thus did not catch overflow reliably. Instead, walk
17964 through the format just once, formatting and computing sizes as we go,
17965 checking for integer overflow at every step, and allocating a larger
17966 buffer as needed. Keep track separately whether the format is
17967 multibyte. Keep only the most-recently calculated precision, rather
17968 than them all. Record whether each argument has been converted to
17969 string. Use EMACS_INT, not int, for byte and char and arg counts.
17970 Support field widths and precisions larger than INT_MAX. Avoid
17971 sprintf's undefined behavior with conversion specifications such as %#d
17972 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17973 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17974 formatting out-of-range floating point numbers with int
17975 formats. (Bug#8668)
17977 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17979 * data.c: Avoid integer truncation in expressions involving floats.
17980 * data.c: Include <intprops.h>.
17981 (arith_driver): When there's an integer overflow in an expression
17982 involving floating point, convert the integers to floating point
17983 so that the resulting value does not suffer from catastrophic
17984 integer truncation. For example, on a 64-bit host (* 4
17985 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17986 Do not rely on undefined behavior after integer overflow.
17988 merge count_size_as_multibyte, parse_str_to_multibyte
17989 * character.c, character.h (count_size_as_multibyte):
17990 Rename from parse_str_to_multibyte; all uses changed.
17991 Check for integer overflow.
17992 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17993 since it's now a duplicate of the other. This is more of
17994 a character than a buffer op, so better that it's in character.c.
17995 * fns.c, print.c: Adjust to above changes.
17997 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17999 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
18001 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
18003 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18004 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
18005 (x_clipboard_manager_save): Now static.
18006 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
18008 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
18009 (crypto_hash_function): Now static.
18010 Fix pointer signedness problems. Avoid unnecessary initializations.
18012 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
18014 * termhooks.h (Vselection_alist): Make it terminal-local.
18016 * terminal.c (create_terminal): Initialize it.
18018 * xselect.c: Support for clipboard managers.
18019 (Vselection_alist): Move to termhooks.h as terminal-local var.
18020 (LOCAL_SELECTION): New macro.
18021 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
18022 (symbol_to_x_atom): Remove gratuitous arg.
18023 (x_handle_selection_request, lisp_data_to_selection_data)
18024 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
18025 (x_own_selection, x_get_local_selection, x_convert_selection):
18026 New arg, specifying work frame. Use terminal-local Vselection_alist.
18027 (some_frame_on_display): Delete unused function.
18028 (Fx_own_selection_internal, Fx_get_selection_internal)
18029 (Fx_disown_selection_internal, Fx_selection_owner_p)
18030 (Fx_selection_exists_p): New optional frame arg.
18031 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
18032 (x_handle_selection_clear): Don't treat other terminals with the
18033 same keyboard specially. Use the terminal-local Vselection_alist.
18034 (x_clear_frame_selections): Use Frun_hook_with_args.
18036 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
18038 * xterm.h: Add support for those atoms.
18040 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
18042 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
18043 (converted_selections, conversion_fail_tag): New global variables.
18044 (x_selection_request_lisp_error): Free the above.
18045 (x_get_local_selection): Remove unnecessary code.
18046 (x_reply_selection_request): Args changed; handle arbitrary array
18047 of converted selections stored in converted_selections.
18048 Separate the XChangeProperty and SelectionNotify steps.
18049 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
18050 (x_convert_selection): New function.
18051 (x_handle_selection_event): Simplify.
18052 (x_get_foreign_selection): Don't ignore incoming requests while
18053 waiting for an answer; this will fail when we implement
18054 SAVE_TARGETS, and seems unnecessary anyway.
18055 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
18056 (Vx_sent_selection_functions): Doc fix.
18058 2011-05-26 Leo Liu <sdl.web@gmail.com>
18060 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
18062 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18064 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
18066 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
18067 for fringe update if it has periodic bitmap.
18068 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
18069 and fringe_bitmap_periodic_p.
18071 * fringe.c (get_fringe_bitmap_data): New function.
18072 (draw_fringe_bitmap_1, update_window_fringes): Use it.
18073 (update_window_fringes): Record periodicity of fringe bitmap in glyph
18074 row. Mark glyph row for fringe update if periodicity changed.
18076 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
18077 for fringe update unless it has periodic bitmap.
18079 2011-05-25 Kenichi Handa <handa@m17n.org>
18081 * xdisp.c (get_next_display_element): Set correct it->face_id for
18082 a static composition.
18084 2011-05-24 Leo Liu <sdl.web@gmail.com>
18087 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18089 * fns.c (crypto_hash_function, Fsha1): New function.
18090 (Fmd5): Use crypto_hash_function.
18091 (syms_of_fns): Add Ssha1.
18093 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18095 * gnutls.c: Remove unused macros.
18096 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18097 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18098 Remove macros that are defined and never used.
18099 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18101 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18103 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18104 (Fx_get_selection_internal): Minor cleanup.
18105 (Fx_own_selection_internal): Rename arguments for consistency with
18108 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18110 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18112 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18114 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18116 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18118 * dispnew.c (scrolling_window): Don't exclude the case that the
18119 last enabled row in the desired matrix touches the bottom boundary.
18121 2011-05-21 Glenn Morris <rgm@gnu.org>
18123 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18124 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18125 and add some more files.
18127 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18129 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18130 report_file_error introduced by the change from 2011-05-07.
18132 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18134 * systime.h (Time): Define only if emacs is defined.
18135 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18136 where the include path doesn't have X11/X.h by default. See
18137 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18139 2011-05-20 Kenichi Handa <handa@m17n.org>
18141 * composite.c (find_automatic_composition): Fix previous change.
18143 2011-05-20 Glenn Morris <rgm@gnu.org>
18145 * lisp.mk: New file, split from Makefile.in.
18146 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18147 (shortlisp): Remove.
18148 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18150 2011-05-19 Glenn Morris <rgm@gnu.org>
18152 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18153 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18154 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18155 (lisp): Set the order to that of loadup.el.
18156 (shortlisp): Make it a copy of $lisp.
18157 (SOME_MACHINE_LISP): Remove.
18158 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18159 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18161 2011-05-18 Kenichi Handa <handa@m17n.org>
18163 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18164 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18165 (find_automatic_composition): Mostly rewrite for efficiency.
18167 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18169 * makefile.w32-in: Update dependencies.
18171 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18173 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18174 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18176 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18178 Fix some integer overflow issues, such as string length overflow.
18180 * insdel.c (count_size_as_multibyte): Check for string overflow.
18182 * character.c (lisp_string_width): Check for string overflow.
18183 Use EMACS_INT, not int, for string indexes and lengths; in
18184 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18185 the resulting string length overflows an EMACS_INT; instead,
18186 report a string overflow if no precision given. When checking for
18187 precision exhaustion, use a check that cannot possibly have
18188 integer overflow. (Bug#8675)
18189 * character.h (lisp_string_width): Adjust to new signature.
18191 * alloc.c (string_overflow): New function.
18192 (Fmake_string): Use it. This doesn't change behavior, but saves
18193 a few bytes and will simplify future changes.
18194 * character.c (string_escape_byte8): Likewise.
18195 * lisp.h (string_overflow): New decl.
18197 Fixups, following up to the user-interface timestamp change.
18198 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18199 for UI timestamps, instead of unsigned long.
18200 * msdos.c (mouse_get_pos): Likewise.
18201 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18202 * w32gui.h (Time): Define by including "systime.h" rather than by
18203 declaring it ourselves. (Bug#8664)
18205 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18206 * image.c (clear_image_cache): Likewise.
18208 * term.c (term_mouse_position): Don't assume time_t wraparound.
18210 Be more systematic about user-interface timestamps.
18211 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18212 and sometimes 'EMACS_UINT', to represent these timestamps.
18213 This change causes it to use 'Time' uniformly, as that's what X uses.
18214 This makes the code easier to follow, and makes it easier to catch
18215 integer overflow bugs such as Bug#8664.
18216 * frame.c (Fmouse_position, Fmouse_pixel_position):
18217 Use Time, not unsigned long, for user-interface timestamps.
18218 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18219 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18220 * keyboard.h (last_event_timestamp): Likewise.
18221 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18222 * menu.h (xmenu_show): Likewise.
18223 * term.c (term_mouse_position): Likewise.
18224 * termhooks.h (struct input_event.timestamp): Likewise.
18225 (struct terminal.mouse_position_hook): Likewise.
18226 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18227 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18228 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18229 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18230 what it was before.
18231 * menu.h, termhooks.h: Include "systime.h", for Time.
18233 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18234 Don't assume that the difference between two unsigned long values
18235 can fit into an integer. At this point, we know button_down_time
18236 <= event->timestamp, so the difference must be nonnegative, so
18237 there's no need to cast the result if double-click-time is
18238 nonnegative, as it should be; check that it's nonnegative, just in
18239 case. This bug is triggered when events are more than 2**31 ms
18240 apart (about 25 days). (Bug#8664)
18242 * xselect.c (last_event_timestamp): Remove duplicate decl.
18243 (x_own_selection): Remove needless cast to unsigned long.
18245 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18246 that always fit in int. Use a sentinel instead of a counter, to
18247 avoid a temp and to allay GCC's concerns about possible int overflow.
18248 * frame.h (struct frame): Use int for menu_bar_items_used
18249 instead of EMACS_INT, since it always fits in int.
18251 * menu.c (grow_menu_items): Check for int overflow.
18253 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18255 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18256 Before, the code was not consistent. These values cannot exceed
18257 2**31 - 1 so there's no need to make them unsigned.
18258 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18259 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18260 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18262 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18264 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18265 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18266 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18267 presumably because the widths might not match.
18269 * window.c (size_window): Avoid needless test at loop start.
18271 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18273 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18275 2011-05-12 Drew Adams <drew.adams@oracle.com>
18277 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18279 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18281 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18282 `width' to `bar_area_x' and `bar_area_width', respectively.
18283 (x_scroll_run): Take account of fringe background extension.
18285 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18286 Rename local vars `left' and `width' to `bar_area_x' and
18287 `bar_area_width', respectively.
18288 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18289 background extension.
18291 2011-05-10 Jim Meyering <meyering@redhat.com>
18293 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18295 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18297 * image.c (Finit_image_library): Return t for built-in image types,
18298 like pbm and xbm. (Bug#8640)
18300 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18302 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18304 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18306 * w32console.c (Fset_screen_color): Doc fix.
18307 (Fget_screen_color): New function.
18308 (syms_of_ntterm): Defsubr it.
18310 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18311 unlink the temporary file if Fcall_process didn't create it in the
18313 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18314 child process will be redirected to a file specified with `:file'.
18315 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18316 cue to call_process_cleanup not to close that handle.
18318 2011-05-07 Ben Key <bkey76@gmail.com>
18320 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18321 one of two shell specific rules, either bootstrap-temacs-CMD or
18322 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18323 to the previous implementation of the bootstrap-temacs rule.
18324 The bootstrap-temacs-CMD rule is similar to the previous
18325 implementation of the bootstrap-temacs rule except that it
18326 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18329 These changes, along with some changes to nt/configure.bat,
18330 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18331 earlier fix to add support for --cflags and --ldflags options
18332 that include quotes so that it works whether make uses cmd or
18335 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18337 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18338 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18340 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18341 a string. Handle both cases.
18342 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18343 (Fdbus_register_method): Use Qinvalid_function.
18345 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18347 * makefile.w32-in: Update dependencies.
18348 (LISP_H): Add inttypes.h and stdin.h.
18349 (PROCESS_H): Add unistd.h.
18351 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18353 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18354 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18356 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18358 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18360 * term.c (vfatal): Remove stray call to va_end.
18361 It's not needed and the C Standard doesn't allow it here anyway.
18363 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18364 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18366 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18369 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18371 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18373 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18375 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18377 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18379 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18380 * charset.c (Fdefine_charset_internal): Don't initialize
18381 charset.code_space[15]. The value was garbage, on hosts with
18382 32-bit int (Bug#8600).
18384 * lread.c (read_integer): Be more consistent with string-to-number.
18385 Use string_to_number to do the actual conversion; this avoids
18386 rounding errors and fixes some other screwups. Without this fix,
18387 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18388 (digit_to_number): Move earlier, for benefit of read_integer.
18389 Return -1 if the digit is out of range for the base, -2 if it is
18390 not a digit in any supported base. (Bug#8602)
18392 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18394 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18395 to match comment at start of function. This also removes a
18396 GCC warning about overflow in a 32+64-bit port.
18398 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18400 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18401 Reported by Stefan Monnier in
18402 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18403 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18404 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18406 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18407 (EMACS_UINTPTR): Likewise, with uintptr_t.
18409 * lisp.h: Prefer 64-bit EMACS_INT if available.
18410 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18411 on 32-bit hosts that have 64-bit int, so that they can access
18413 However, temporarily disable this change unless the temporary
18414 symbol WIDE_EMACS_INT is defined.
18416 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18418 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18419 This removes an assumption that EMACS_INT and long are the same
18420 width as pointers. The assumption is true for Emacs porting targets
18421 now, but we want to make other targets possible.
18422 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18423 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18424 In the rest of the code, change types of integers that hold casted
18425 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18426 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18427 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18428 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18429 No need to cast type when ORing.
18430 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18431 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18432 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18433 assume EMACS_INT is the same width as char *.
18434 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18435 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18436 Remove no-longer-needed casts.
18437 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18438 (xg_tool_bar_help_callback, xg_make_tool_item):
18439 Use EMACS_INTPTR to hold an integer
18440 that will be cast to void *; this can avoid a GCC warning
18441 if EMACS_INT is not the same width as void *.
18442 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18443 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18444 (current_message_1, set_message_1):
18445 Use a local to convert to proper width without a cast.
18446 * xmenu.c (dialog_selection_callback): Likewise.
18448 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18449 Also, don't assume VALBITS / RAND_BITS is less than 5,
18450 and don't rely on undefined behavior when shifting a 1 left into
18452 * lisp.h (get_random): Change signature to match.
18454 * lread.c (hash_string): Use size_t, not int, for hash computation.
18455 Normally we prefer signed values; but hashing is special, because
18456 it's better to use unsigned division on hash table sizes so that
18457 the remainder is nonnegative. Also, size_t is the natural width
18458 for hashing into memory. The previous code used 'int', which doesn't
18459 retain enough info to hash well into very large tables.
18460 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18462 * dbusbind.c: Don't possibly lose pointer info when converting.
18463 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18464 Use XPNTR rather than XHASH, so that the high-order bits of
18465 the pointer aren't lost when converting through void *.
18467 * eval.c (Fautoload): Don't double-shift a pointer.
18469 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18471 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18473 * gnutls.c (DEF_GNUTLS_FN):
18474 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18476 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18478 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18481 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18483 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18484 New version that can reserve upto 2GB of heap space.
18486 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18488 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18490 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18492 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18493 `gnutls_certificate_set_x509_key_file'.
18495 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18497 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18498 Update dependencies.
18500 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18502 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18503 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18504 Remove unused parameter `fildes'.
18505 * process.c (read_process_output, send_process): Don't pass it.
18507 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18509 Fix previous change: the library cache is defined in w32.c.
18510 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18511 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18513 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18515 Implement dynamic loading of GnuTLS on Windows.
18517 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18518 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18519 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18522 * gnutls.c (Qgnutls_dll): Define.
18523 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18524 (gnutls_*): Declare function pointers.
18525 (init_gnutls_functions): New function to initialize function pointers.
18526 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)

18528 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18529 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18530 (emacs_gnutls_write, emacs_gnutls_read)
18531 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18532 (Fgnutls_available_p): New function.
18533 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
18534 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
18535 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
18537 * image.c: Include w32.h.
18538 (Vimage_type_cache): Delete.
18539 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
18540 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
18541 (w32_delayed_load): Move to w32.c.
18543 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
18545 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18546 (w32_delayed_load): Move from image.c. When loading a library, record
18547 its filename in the :loaded-from property of the library id.
18548 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18549 Initialize and staticpro them.
18550 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18552 * process.c: Include lisp.h before w32.h, not after.
18553 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18554 instead of gnutls_record_check_pending.
18556 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18558 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18560 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18561 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18564 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18566 * xterm.c (x_set_frame_alpha): Do not set property on anything
18567 else than FRAME_X_OUTER_WINDOW (Bug#8608).

18587 * callproc.c: Indentation fixup.
18589 * sysdep.c (wait_for_termination_1): Make static.
18590 (wait_for_termination, interruptible_wait_for_termination):
18591 Move after wait_for_termination_1.
18593 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18595 * sysdep.c (interruptible_wait_for_termination): New function
18596 which is like wait_for_termination, but allows keyboard
18599 * callproc.c (Fcall_process): Add (:file "file") as an option for
18601 (Fcall_process_region): Ditto.
18603 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18605 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18606 rather than `XVECTOR (FOO)->size'.
18608 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18609 inttypes.h, as a gnulib replacement is used if it not available in
18612 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18614 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18615 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18616 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18618 * coding.c (coding_alloc_by_realloc): Error out if destination
18619 will grow beyond MOST_POSITIVE_FIXNUM.
18620 (decode_coding_emacs_mule): Abort if there isn't enough place in

18631 %llo or %llx format is passed. (Bug#8545)
18633 * window.c (window_scroll_line_based): Use a marker instead of
18634 simple variables to record original value of point. (Bug#7952)
18636 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18637 produced by %s or %c overflows available buffer space. (Bug#8545)
18639 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18641 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
18642 (SIZE_MAX): Move defn after all includes, as they might #define it.
18644 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
18646 * w32.c (init_environment): Warn about defaulting HOME to C:\.

18666 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18668 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
18670 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
18672 * makefile.w32-in: Update dependencies.
18674 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18676 Improve `doprnt' and its usage. (Bug#8545)
18677 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18678 `format_end'. Remove support for %l as a conversion specifier.
18679 Don't use xrealloc. Improve diagnostics when the %l size modifier
18680 is used. Update the commentary.
18682 * eval.c (verror): Simplify calculation of size_t.
18684 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18687 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18689 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18692 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18694 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18695 This makes this file independent of the recent pseudovector change.
18697 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18699 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18701 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18702 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18703 Remove unused local.
18704 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18706 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18707 GCC 4.6.0 optimizes based on type-based alias analysis.
18708 For example, if b is of type struct buffer * and v of type struct
18709 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18710 != &v->size, and therefore "v->size = 1; b->size = 2; return
18711 v->size;" must therefore return 1. This assumption is incorrect
18712 for Emacs, since it type-puns struct Lisp_Vector * with many other
18713 types. To fix this problem, this patch adds a new type struct
18714 vectorlike_header that documents the constraints on layout of vectors
18715 and pseudovectors, and helps optimizing compilers not get fooled
18716 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18717 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18718 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18720 (XSETPVECTYPE): Rewrite in terms of new macro.
18721 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18722 This is a bit clearer, and further avoids the possibility of
18723 undesirable aliasing.
18724 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18725 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18726 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18727 since Lisp_Subr is a special case (no "next" field).
18728 (ASIZE): Now uses header.size rather than size.
18729 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18730 to avoid the hassle of writing XVECTOR (foo)->header.size.
18731 (struct vectorlike_header): New type.
18732 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18733 object, to help avoid aliasing.
18734 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18735 (SUBRP): Likewise, since Lisp_Subr is a special case.
18736 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18737 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18738 (struct Lisp_Hash_Table): Combine first two members into a single
18739 struct vectorlike_header member. All uses of "size" and "next" members
18740 changed to be "header.size" and "header.next".
18741 * buffer.h (struct buffer): Likewise.
18742 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18743 * frame.h (struct frame): Likewise.
18744 * process.h (struct Lisp_Process): Likewise.
18745 * termhooks.h (struct terminal): Likewise.
18746 * window.c (struct save_window_data, struct saved_window): Likewise.
18747 * window.h (struct window): Likewise.
18748 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18749 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18750 * buffer.c (init_buffer_once): Likewise.
18751 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18753 * process.c (Fformat_network_address): Use local var for size,
18756 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18758 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18759 * data.c (atof): Remove decl; no longer used or needed.
18760 (digit_to_number): Move to lread.c.
18761 (Fstring_to_number): Use new string_to_number function, to be
18762 consistent with how the Lisp reader treats infinities and NaNs.
18763 Do not assume that floating-point numbers represent EMACS_INT
18764 without losing information; this is not true on most 64-bit hosts.
18765 Avoid double-rounding errors, by insisting on integers when
18766 parsing non-base-10 numbers, as the documentation specifies.
18767 * lisp.h (string_to_number): New decl, replacing ...
18768 (isfloat_string): Remove.
18769 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18770 (read1): Do not accept +. and -. as integers; this
18771 appears to have been a coding error. Similarly, do not accept
18772 strings like +-1e0 as floating point numbers. Do not report
18773 overflow for integer overflows unless the base is not 10 which
18774 means we have no simple and reliable way to continue.
18775 Break out the floating-point parsing into a new
18776 function string_to_number, so that Fstring_to_number parses
18777 floating point numbers consistently with the Lisp reader.
18778 (digit_to_number): Move here from data.c. Make it static inline.
18779 (E_CHAR, EXP_INT): Remove, replacing with ...
18780 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18781 (string_to_number): New function, replacing isfloat_string.
18782 This function checks for valid syntax and produces the resulting
18783 Lisp float number too. Rework it so that string-to-number
18784 no longer mishandles examples like "1.0e+". Use strtoumax,
18785 so that overflow for non-base-10 numbers is reported only when
18786 there's no portable and simple way to convert to floating point.
18788 * textprop.c (set_text_properties_1): Rewrite for clarity,
18789 and to avoid GCC warning about integer overflow.
18791 * intervals.h (struct interval): Use EMACS_INT for members
18792 where EMACS_UINT might cause problems. See
18793 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18794 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18795 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18797 (offset_intervals): Tell GCC not to worry about length overflow
18798 when negating a negative length.
18800 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18801 (overrun_check_free): Likewise.
18803 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18804 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18807 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18808 (gnutls_make_error): Rename local to avoid shadowing.
18809 (gnutls_emacs_global_deinit): ifdef out; not used.
18810 (Fgnutls_boot): Use const for pointer to readonly storage.
18811 Comment out unused local. Fix pointer signedness problems.
18813 * lread.c (openp): Don't stuff size_t into an 'int'.
18814 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18815 about possible signed overflow.
18817 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18818 (GDK_KEY_g): Don't define if already defined.
18819 (xg_prepare_tooltip): Avoid pointer signedness problem.
18820 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18822 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18823 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18825 * xfns.c (Fx_window_property): Simplify a bit,
18826 to make a bit faster and to avoid GCC 4.6.0 warning.
18827 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18829 * fns.c (internal_equal): Don't assume size_t fits in int.
18831 * alloc.c (compact_small_strings): Tighten assertion a little.
18833 Replace pEd with more-general pI, and fix some printf arg casts.
18834 * lisp.h (pI): New macro, generalizing old pEd macro to other
18835 conversion specifiers. For example, use "...%"pI"d..." rather
18836 than "...%"pEd"...".
18837 (pEd): Remove. All uses replaced with similar uses of pI.
18838 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18839 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18840 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18841 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18842 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18843 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18844 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18846 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18847 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18848 * print.c (safe_debug_print, print_object): Likewise.
18849 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18851 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18852 avoiding the 0 flag, which is not portable.
18853 * process.c (Fmake_network_process): Use pI to avoid cast.
18854 * region-cache.c (pp_cache): Likewise.
18855 * xdisp.c (decode_mode_spec): Likewise.
18856 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18857 behavior on 64-bit hosts with printf arg.
18858 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18859 (x_stop_queuing_selection_requests): Likewise.
18860 (x_get_window_property): Don't truncate byte count to an 'int'
18863 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18864 here, since it parses constructs like leading '-' and spaces,
18865 which are not wanted; and it overflows with large numbers.
18866 Instead, simply match F[0-9]+, which is what is wanted anyway.
18868 * alloc.c: Remove unportable assumptions about struct layout.
18869 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18870 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18871 (allocate_vectorlike, make_pure_vector): Use the new macros,
18872 plus offsetof, to remove unportable assumptions about struct layout.
18873 These assumptions hold on all porting targets that I know of, but
18874 they are not guaranteed, they're easy to remove, and removing them
18875 makes further changes easier.
18877 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18878 This doesn't fix a bug but makes the code clearer.
18879 (string_overrun_cookie): Now const. Use initializers that
18880 don't formally overflow signed char, to avoid warnings.
18881 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18882 can cause Emacs to crash when string overrun checking is enabled.
18883 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18884 multiple of sizeof (EMACS_INT); it need not be, if
18885 alignof(EMACS_INT) < sizeof (EMACS_INT).
18886 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18888 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18895 supposed to be handshaking. (Bug#8556)
18896 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18898 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

18904 matches the current signal symbol.
18906 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
18908 * alloc.c (check_sblock, check_string_bytes)
18909 (check_string_free_list): Convert to standard C.
18911 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
18913 * w32.c (emacs_gnutls_push): Fix typo.
18915 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18917 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18918 "cast to pointer from integer of different size".
18920 Improve doprnt and its use in verror. (Bug#8545)
18921 * doprnt.c (doprnt): Document the set of format control sequences
18922 supported by the function. Use SAFE_ALLOCA instead of always
18925 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18926 is one byte too soon. Don't use xrealloc; instead xfree and
18929 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18931 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18934 * gnutls.c: Renamed global_initialized to
18935 gnutls_global_initialized. Added internals for the
18936 :verify-hostname-error, :verify-error, and :verify-flags
18937 parameters of `gnutls-boot' and documented those parameters in the
18938 docstring. Start callback support.
18939 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18940 unless a fatal error occurred. Call gnutls_alert_send_appropriate
18941 on error. Return error code.
18942 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
18943 (emacs_gnutls_read): Likewise.
18944 (Fgnutls_boot): Return handshake error code.
18945 (emacs_gnutls_handle_error): New function.
18946 (wsaerror_to_errno): Likewise.

19008 <char-direction-table>: Deleted.
19010 2011-04-23 Eli Zaretskii <eliz@gnu.org>
19012 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
19013 * doprnt.c: Include limits.h.
19014 (SIZE_MAX): New macro.
19015 (doprnt): Return a size_t value. 2nd arg is now size_t.
19016 Many local variables are now size_t instead of int or unsigned.
19017 Improve overflow protection. Support `l' modifier for integer
19018 conversions. Support %l conversion. Don't assume an EMACS_INT
19019 argument for integer conversions and for %c.
19021 * lisp.h (doprnt): Restore prototype.
19023 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
19024 $(SRC)/character.h.
19026 * Makefile.in (base_obj): Add back doprnt.o.
19028 * deps.mk (doprnt.o): Add back prerequisites.
19029 (callint.o): Depend on character.h.
19031 * eval.c (internal_lisp_condition_case): Include the handler
19032 representation in the error message.
19033 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
19034 when breaking from the loop.
19036 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
19038 * callint.c (Fcall_interactively): When displaying error message
19039 about invalid control letter, pass the character's codepoint, not
19040 a pointer to its multibyte form. Improve display of the character
19041 in octal and display also its hex code.
19043 * character.c (char_string): Use %x to display the (unsigned)
19044 codepoint of an invalid character, to avoid displaying a bogus
19047 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
19048 `error', not SYMBOL_NAME itself.
19050 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
19051 character arguments to `error'.
19053 * charset.c (check_iso_charset_parameter): Fix incorrect argument
19054 to `error' in error message about FINAL_CHAR argument. Make sure
19055 FINAL_CHAR is a character, and use %c when it is passed as
19056 argument to `error'.

19120 Define only if needed.
19122 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
19123 by pacifying GCC about it. Maybe it's time to retire it?
19124 * xfaces.c (USG, __TIMEVAL__): Likewise.
19126 * dispextern.h (struct redisplay_interface): Rename param
19127 to avoid shadowing.
19128 * termhooks.h (struct terminal): Likewise.
19129 * xterm.c (xembed_send_message): Likewise.
19131 * insdel.c (make_gap_smaller): Define only if

19269 * process.c (send_process): Adjust to the new signatures of
19270 emacs_write and emacs_gnutls_write. Do not attempt to store

19591 * ccl.h (check_ccl_update, Vccl_program_table): Remove decls.
19592 * ccl.c (Vccl_program_table): Now static.
19593 (check_ccl_update): Remove; unused.
19595 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
19596 * category.h: ... from here.
19597 * category.c (check_category_table, set_category_set): Now static.
19599 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
19600 * lisp.h: Remove these decls.
19602 * buffer.c (buffer_count): Remove unused var.
19604 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
19605 so that it's not optimized away.
19606 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
19607 * dispextern.h (bidi_dump_cached_states): Remove, since it's
19608 exported only to the debugger.
19610 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
19611 * atimer.h (run_all_atimers): Remove; not exported.
19613 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
19614 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
19615 was inaccessible from Lisp.
19616 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
19617 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
19619 alloc.c: Import and export fewer symbols, and remove unused items.
19620 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
19622 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
19623 it's not optimized away by whole-program optimization.
19624 (message_enable_multibyte, free_misc): Remove.
19625 (catchlist, handlerlist, mark_backtrace):
19626 Declare only if BYTE_MARK_STACK.
19627 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
19628 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
19629 (message_enable_multibyte): Remove decl.
19630 (free_misc, interval_free_list, float_block, float_block_index):
19631 (n_float_blocks, float_free_list, cons_block, cons_block_index):
19632 (cons_free_list, last_marked_index):
19634 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
19635 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
19636 (mark_backtrace): Define only if BYTE_MARK_STACK.
19637 * xdisp.c (message_enable_multibyte): Now static.
19639 Declare Lisp_Object Q* variables to be 'static' if not exported.
19640 This makes it easier for human readers (and static analyzers)
19641 to see whether these variables are used from other modules.
19642 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
19643 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
19644 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

19647 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
19648 * xmenu.c, xselect.c:
19649 Declare Q* vars static if they are not used in other modules.
19650 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
19651 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
19652 Remove decls of unexported vars.
19653 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
19655 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19657 Make Emacs functions such as Fatom 'static' by default.
19658 This makes it easier for human readers (and static analyzers)
19659 to see whether these functions can be called from other modules.
19660 DEFUN now defines a static function. To make the function external
19661 so that it can be used in other C modules, use the new macro DEFUE.
19662 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
19663 (Finit_image_library):
19664 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
19665 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
19666 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
19667 Remove decls, since these functions are now static.
19668 (Funintern, Fget_internal_run_time): New decls, since these functions
19669 were already external.
19671 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
19672 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

19678 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
19679 Mark functions with DEFUE instead of DEFUN,
19680 if they are used in other modules.
19681 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19682 decls for now-static functions.
19683 * buffer.h (Fdelete_overlay): Remove decl.
19684 * callproc.c (Fgetenv_internal): Mark as internal.
19685 * composite.c (Fremove_list_of_text_properties): Remove decl.

19691 (Funintern): Remove extern decl; now in .h file where it belongs.
19692 * fileio.c (Fmake_symbolic_link): New forward static decl.
19693 * image.c (Finit_image_library): New forward static decl.
19694 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
19695 * intervals.h (Fprevious_property_change):
19696 (Fremove_list_of_text_properties): Remove decls.
19697 * keyboard.c (Fthis_command_keys): Remove decl.
19698 (Fcommand_execute): New forward static decl.
19699 * keymap.c (Flookup_key): New forward static decl.
19700 (Fcopy_keymap): Now static.
19701 * keymap.h (Flookup_key): Remove decl.
19702 * process.c (Fget_process): New forward static decl.
19703 (Fprocess_datagram_address): Mark as internal.

19714 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
19716 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
19719 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19721 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19722 when at ZV. (Bug#8487)
19724 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19726 * charset.c (Fclear_charset_maps): Use xfree instead of free.
19728 * keyboard.c (parse_tool_bar_item): Likewise.
19729 * sound.c (sound_cleanup, alsa_close): Likewise.
19730 * termcap.c (tgetent): Likewise.
19731 * xfns.c (x_default_font_parameter): Likewise.
19732 * xsettings.c (read_and_apply_settings): Likewise.
19734 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19735 (overrun_check_free): Protoize.
19737 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19739 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19740 since callers should never pass a negative size.
19741 Change the signature to match that of plain 'read' and 'write'; see
19742 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19743 * lisp.h: Update prototypes of emacs_write and emacs_read.
19745 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19747 * xdisp.c (redisplay_window): Don't try to determine the character
19748 position of the scroll margin if the window start point w->startp
19749 is outside the buffer's accessible region. (Bug#8468)
19751 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19753 Fix write-region and its subroutines for buffers > 2GB.
19754 * fileio.c (a_write, e_write): Modify declaration of arguments and
19755 local variables to support buffers larger than 2GB.
19756 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19758 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19759 argument, local variables, and return value.
19761 * lisp.h: Update prototypes of emacs_write and emacs_read.
19763 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19765 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19767 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19769 Fix more problems found by GCC 4.6.0's static checks.
19771 * xdisp.c (vmessage): Use a better test for character truncation.
19773 * charset.c (load_charset_map): <, not <=, for optimization,
19774 and to avoid potential problems with integer overflow.
19775 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19776 * casetab.c (set_identity, shuffle): Likewise.
19777 * editfns.c (Fformat): Likewise.
19778 * syntax.c (skip_chars): Likewise.
19780 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19781 This also lets GCC 4.6.0 generate slightly better loop code.
19783 * callint.c (Fcall_interactively): <, not <=, for optimization.
19784 (Fcall_interactively): Count the number of arguments produced,
19785 not the number of arguments given. This is simpler and lets GCC
19786 4.6.0 generate slightly better code.
19788 * ftfont.c: Distingish more carefully between FcChar8 and char.
19789 The previous code passed unsigned char * to a functions like
19790 strlen and xstrcasecmp that expect char *, which does not
19791 conform to the C standard.
19792 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19793 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19794 char * when the C standard requires it.
19796 * keyboard.c (read_char): Remove unused var.
19798 * eval.c: Port to Windows vsnprintf (Bug#8435).
19799 Include <limits.h>.
19800 (SIZE_MAX): Define if the headers do not.
19801 (verror): Do not give up if vsnprintf returns a negative count.
19802 Instead, grow the buffer. This ports to Windows vsnprintf, which
19803 does not conform to C99. Problem reported by Eli Zaretskii.
19804 Also, simplify the allocation scheme, by avoiding the need for
19805 calling realloc, and removing the ALLOCATED variable.
19807 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19809 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19810 But keep the doprint source code for now, as we might revamp it
19811 and use it again (Bug#8435).
19812 * lisp.h (doprnt): Remove.
19813 * Makefile.in (base_obj): Remove doprnt.o.
19814 * deps.mk (doprnt.o): Remove.
19816 error: Print 32- and 64-bit integers portably (Bug#8435).
19817 Without this change, on typical 64-bit hosts error ("...%d...", N)
19818 was used to print both 32- and 64-bit integers N, which relied on
19819 undefined behavior.
19820 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19821 * lisp.h (error, verror): Mark as printf-like functions.
19822 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19823 Report overflow in size calculations when allocating printf buffer.
19824 Do not truncate output string at its first null byte.
19825 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19826 Truncate the output at a character boundary, since vsnprintf does not
19828 * charset.c (check_iso_charset_parameter): Convert internal
19829 character to string before calling 'error', since %c now has the
19831 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19832 overflow when computing char to be passed to 'error'. Do not
19833 pass Lisp_Object to 'error'; pass the integer instead.
19834 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19835 formatted with plain %d.
19837 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19839 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19841 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19843 * xterm.c (x_catch_errors): Remove duplicate declaration.
19845 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19847 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19849 2011-04-10 Jim Meyering <meyering@redhat.com>
19851 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19852 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19853 return ssize_t not "int", and use size_t as the buffer length.
19854 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19855 * gnutls.h: Update declarations.
19856 * process.c (read_process_output): Use ssize_t, to match.
19857 (send_process): Likewise.
19859 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19861 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19863 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19865 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19866 Use unsigned char, to match FcChar8 type definition.
19868 * xterm.c (handle_one_xevent):
19869 * xmenu.c (create_and_show_popup_menu):
19870 * xselect.c (x_decline_selection_request)
19871 (x_reply_selection_request): Avoid type-punned deref of X events.
19873 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19875 Fix some uses of `int' instead of EMACS_INT.
19876 * search.c (string_match_1, fast_string_match)
19877 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19878 (scan_buffer, find_next_newline_no_quit)
19879 (find_before_next_newline, search_command, Freplace_match)
19880 (Fmatch_data): Make some `int' variables be EMACS_INT.
19882 * xdisp.c (display_count_lines): 3rd argument and return value now
19883 EMACS_INT. All callers changed.
19884 (pint2hrstr): Last argument is now EMACS_INT.
19886 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19887 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19888 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
19889 (decode_coding_utf_16, decode_coding_emacs_mule)

19891 (decode_coding_ccl, decode_coding_charset)
19892 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
19893 (decode_coding_iso_2022, decode_coding_emacs_mule)
19894 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
19895 <char_offset, last_offset>: Declare EMACS_INT.

19899 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19900 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19902 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19903 (encode_invocation_designation): Last argument P_NCHARS is now
19905 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19906 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19908 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19911 * ccl.c (Fccl_execute_on_string): Declare some variables
19914 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19916 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19918 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19920 * process.c (Fformat_network_address): Doc fix.
19922 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19924 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19926 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19928 * keyboard.c (read_char): Call Lisp function help-form-show,
19929 instead of using internal_with_output_to_temp_buffer.
19930 (Qhelp_form_show): New var.
19931 (syms_of_keyboard): Use DEFSYM macro.
19933 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19940 (list_processes_1): Delete.
19942 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19944 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19946 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19948 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19950 Fix more problems found by GCC 4.6.0's static checks.
19952 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
19954 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19956 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19958 * xdisp.c (vmessage): Mark as a printf-like function.
19960 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19962 * sound.c (sound_warning): Don't crash if arg contains a printf format.
19964 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
19965 printf-like functions.
19966 (tiff_load): Add casts to remove these marks before passing them
19967 to system-supplied API.
19969 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19971 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19972 This avoids several warnings with gcc -Wstrict-overflow.
19973 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19974 directly, rather than having caller test rule sign. This avoids
19975 some unnecessary tests.
19976 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19977 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19978 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19980 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19981 (xfont_open): Avoid unnecessary tests.
19983 * composite.c (composition_gstring_put_cache): Use unsigned integer.

19992 by using the new macro.
19994 * textprop.c (set_text_properties_1): Change while to do-while,
19995 since the condition is always true at first.
19997 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19998 (interval_deletion_adjustment): Return unsigned value.
20001 * process.c (list_processes_1, create_pty, read_process_output):

20017 * print.c (print_error_message): Avoid int overflow.
20019 * font.c (font_list_entities): Redo for clarity,
20020 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.

20035 (wordify): Omit three unnecessary tests.
20037 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

20042 * dired.c (file_name_completion): Remove var that is set but not used.
20044 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
20046 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.

20049 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
20050 Check for integer overflow on size calculations.
20052 * buffer.c (Fprevious_overlay_change): Remove var that is set
20055 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
20056 Remove vars that are set but not used.
20057 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
20058 (timer_check_2): Mark vars as initialized.
20060 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
20062 * image.c (lookup_image): Remove var that is set but not used.
20063 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
20065 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
20066 that are set but not used.
20068 * xfns.c (make_invisible_cursor): Don't return garbage
20069 if XCreateBitmapFromData fails (Bug#8410).
20071 * xselect.c (x_get_local_selection, x_handle_property_notify):
20072 Remove vars that are set but not used.
20074 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
20075 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
20077 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20078 Remove var that is set but not used.
20079 (scroll_bar_windows_size): Now size_t, not int.
20080 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20081 Check for overflow.
20083 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20084 (map_tty_color) [!defined MSDOS]: Likewise.
20086 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20088 * coding.c: Remove vars that are set but not used.
20089 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
20090 All callers changed.
20091 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
20092 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
20093 (decode_coding_charset): Remove vars that are set but not used.
20095 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
20096 that is set but not used.
20098 * print.c (print_object): Remove var that is set but not used.
20100 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20101 The gnulib version avoids calling malloc in the usual case,
20102 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20103 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20104 * filelock.c (current_lock_owner): Likewise.
20105 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20106 * sysdep.c: Include allocator.h, careadlinkat.h.
20107 (emacs_no_realloc_allocator): New static constant.
20108 (emacs_readlink): New function.
20109 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20110 ../lib/careadlinkat.h.
20112 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20114 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
20115 first non-nil return value).

20136 do not dereference NULL upon failed strdup
20137 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20138 (ns_get_family): Likewise.
20140 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20142 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20144 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20146 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20149 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20151 Add lexical binding.
20153 * window.c (Ftemp_output_buffer_show): New fun.
20154 (Fsave_window_excursion):
20155 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
20157 * lread.c (lisp_file_lexically_bound_p): New function.
20158 (Fload): Bind Qlexical_binding.
20159 (readevalloop): Remove `evalfun' arg.
20160 Bind Qinternal_interpreter_environment.
20161 (Feval_buffer): Bind Qlexical_binding.
20162 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20164 (syms_of_lread): Declare `lexical-binding'.
20166 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20168 * keyboard.c (eval_dyn): New fun.
20169 (menu_item_eval_property): Use it.
20171 * image.c (parse_image_spec): Use Ffunctionp.
20173 * fns.c (concat, mapcar1): Accept byte-code-functions.
20175 * eval.c (Fsetq): Handle lexical vars.
20176 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20177 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20178 (FletX, Flet): Obey lexical binding.
20179 (Fcommandp): Handle closures.
20180 (Feval): New `lexical' arg.
20181 (eval_sub): New function extracted from Feval. Use it almost
20182 everywhere where Feval was used. Look up vars in lexical env.
20184 (Ffunctionp): Move from subr.el.
20185 (Ffuncall): Handle closures.
20186 (apply_lambda): Remove `eval_flags'.
20187 (funcall_lambda): Handle closures and new byte-code-functions.
20188 (Fspecial_variable_p): New function.
20189 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20190 but without exporting it to Lisp.
20192 * doc.c (Fdocumentation, store_function_docstring):
20193 * data.c (Finteractive_form): Handle closures.
20195 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20198 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20200 (exec_byte_code): New function extracted from Fbyte_code to handle new
20201 calling convention for byte-code-functions. Add new byte-codes.
20203 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20205 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20207 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20209 * xdisp.c (redisplay_internal): Fix prototype.
20211 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20213 * xdisp.c (SCROLL_LIMIT): New macro.
20214 (try_scrolling): Use it when setting scroll_limit.
20215 Limit scrolling to 100 screen lines.
20216 (redisplay_window): Even when falling back on "recentering",
20217 position point in the window according to scroll-conservatively,
20218 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20220 (try_scrolling): When point is above the window, allow searching
20221 as far as scroll_max, or one screenful, to compute vertical
20222 distance from PT to the scroll margin position. This prevents
20223 try_scrolling from unnecessarily failing when
20224 scroll-conservatively is set to a value slightly larger than the
20225 window height. Clean up the case of PT below the margin at bottom
20226 of window: scroll_max can no longer be INT_MAX. When aggressive
20227 scrolling is in use, don't let point enter the opposite scroll
20228 margin as result of the scroll.
20229 (syms_of_xdisp) <scroll-conservatively>: Document the
20230 threshold of 100 lines for never-recentering scrolling.
20232 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20234 * dispextern.h (move_it_by_lines):

20237 (message_log_check_duplicate): Remove parameters `prev_bol' and
20238 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20239 (redisplay_internal): Remove parameter `preserve_echo_area',
20240 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20242 * indent.c (Fvertical_motion):
20243 * window.c (window_scroll_pixel_based, Frecenter):
20244 Don't pass `need_y_p' to `move_it_by_lines'.
20246 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20248 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20249 steal a few bits to be more compact.
20250 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20251 Remove unneeded casts.
20253 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20255 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20257 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20258 binding" message (bug#7967).
20260 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20262 Fix more problems found by GCC 4.6.0's static checks.
20264 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20265 Remove unused local var.
20267 * editfns.c (Fmessage_box): Remove unused local var.
20269 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20270 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20271 Omit unused local vars.
20272 * window.c (shrink_windows): Omit unused local var.
20273 * menu.c (digest_single_submenu): Omit unused local var.
20274 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20275 Omit unused local var.
20277 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20278 Don't assume string length fits in int.
20279 (keyremap_step, read_key_sequence): Use size_t for sizes.
20280 (read_key_sequence): Don't check last_real_key_start redundantly.
20282 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20283 instead of alloca (Bug#8344).
20285 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20286 (Fbacktrace_frame): Don't assume nframes fits in int.
20288 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
20290 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
20293 * term.c (produce_glyphless_glyph): Remove unnecessary test.
20295 * cm.c (calccost): Turn while-do into do-while, for clarity.
20297 * keyboard.c (syms_of_keyboard): Use the same style as later
20298 in this function when indexing through an array. This also
20299 works around GCC bug 48267.
20301 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20303 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20305 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20306 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20308 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20309 This avoids undefined behavior on integer overflow, and is a bit
20310 more convenient anyway since it is compared to a size_t variable.
20312 Variadic C functions now count arguments with size_t, not int.
20313 This avoids an unnecessary limitation on 64-bit machines, which
20314 caused (substring ...) to crash on large vectors (Bug#8344).

20324 * fns.c (concat): Likewise.
20325 * frame.c (x_set_frame_parameters): Likewise.
20326 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20327 0 if not found, not -1. All callers changed.
20329 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20330 (stack_copy_size): Now size_t, not int.
20331 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20333 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20335 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20336 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
20337 All callers changed.

20352 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20353 don't set the hook to nil, but remove the offending function instead.
20354 (Qcommand_hook_internal): Remove, unused.
20355 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20356 Vcommand_hook_internal.
20358 * eval.c (enum run_hooks_condition): Remove.
20359 (funcall_nil, funcall_not): New functions.
20360 (run_hook_with_args): Call each function through a `funcall' argument.

20374 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
20375 All callers changed.
20377 * w32.c (_wsa_errlist): Use braces for struct initializers.
20379 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

20432 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
20434 * keyboard.c (timer_check): Remove parameter `do_it_now',

20537 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20539 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20540 unconditionally since it does the check itself.
20542 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20544 Fix more problems found by GCC 4.5.2's static checks.
20546 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20547 the first time through the loop, since we know p0 < p1 then.
20548 This also avoids a gcc -Wstrict-overflow warning.
20550 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20551 leading to a memory leak, possible in functions like
20552 load_charset_map_from_file that can allocate an unbounded number
20553 of objects (Bug#8318).
20555 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20556 that could (at least in theory) be that large.
20558 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20559 This is less likely to overflow, and avoids undefined behavior if
20560 overflow does occur. All callers changed. Use strtoul to scan
20561 for the unsigned long integer.
20562 (pint2hrstr): Simplify and tune code slightly.
20563 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

20573 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20576 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20578 * process.c (Fmake_network_process): Use socklen_t, not int,
20579 where POSIX says socklen_t is required in portable programs.
20580 This fixes a porting bug on hosts like 64-bit HP-UX, where
20581 socklen_t is wider than int (Bug#8277).
20582 (Fmake_network_process, server_accept_connection):
20583 (wait_reading_process_output, read_process_output):
20586 * process.c: Rename or move locals to avoid shadowing.

20596 Make tparam.h and terminfo.c consistent.
20597 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20598 Include tparam.h instead, since it declares them.
20599 * cm.h (PC): Remove extern decl; tparam.h now does this.
20600 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20601 * terminfo.c: Include tparam.h, to check interfaces.
20602 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20603 (tparam): Adjust signature to match interface in tparam.h;
20604 this removes some undefined behavior. Check that outstring and len
20605 are zero, which they always are with Emacs.
20606 * tparam.h (PC, BC, UP): New extern decls.
20608 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20609 (xftfont_open): Rename locals to avoid shadowing.

20626 (find_automatic_composition, composition_adjust_point): Likewise.
20627 (composition_update_it): Mark var as initialized.
20628 (find_automatic_composition): Mark vars as initialized,
20629 with a FIXME (Bug#8290).

20633 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20634 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20635 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20636 to avoid shadowing.
20638 * textprop.c (property_change_between_p): Remove; unused.
20640 * intervals.c (interval_start_pos): Now static.
20642 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

20648 Fix pointer signedness.
20649 (alsa_choose_format): Remove unused local var.
20650 (wav_play): Initialize a variable to 0, to prevent undefined
20651 behavior (Bug#8278).
20653 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20655 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20657 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20658 clobbering (Bug#8298).
20659 * sysdep.c (sys_subshell): Likewise.
20660 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20662 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20663 This should get cleaned up, so that child_setup has the
20664 same signature on all platforms.
20666 * callproc.c (call_process_cleanup): Now static.
20667 (relocate_fd): Rename locals to avoid shadowing.
20669 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20671 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20672 not to be necessary, and produces flickering.
20674 2011-03-20 Glenn Morris <rgm@gnu.org>
20676 * config.in: Remove file.
20678 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

20692 * xfaces.c (Fx_load_color_file):
20693 Read color file from absolute filename (bug#8250).

20708 (sigchld_handler): Now static.
20710 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
20711 That way, the code declares only the vars that it needs.

20721 (CONSTANTLIM): Remove; unused.
20722 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
20723 Define only if needed.
20725 * unexelf.c (unexec): Name an expression,
20726 to avoid gcc -Wbad-function-cast warning.
20727 Use a different way to cause a compilation error if anyone uses
20728 n rather than nn, a way that does not involve shadowing.
20729 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20731 * deps.mk (unexalpha.o): Remove; unused.
20733 New file unexec.h, the (simple) interface for unexec (Bug#8267).

20804 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
20807 * lisp.h (eassert): Check that the argument compiles, even if
20808 ENABLE_CHECKING is not defined.
20810 * data.c (Findirect_variable): Name an expression, to avoid
20811 gcc -Wbad-function-cast warning.

20823 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
20824 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
20826 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
20827 (GC_STRING_CHARS): Remove; not used.
20828 (Fmemory_limit): Cast sbrk's returned value to char *.

20854 (RETALLOC_IF): Define only if needed.
20855 (WORDCHAR_P): Likewise. This one is never needed, but is used
20856 only in a comment talking about a compiler bug, so put inside
20857 the #if 0 of that comment.

20885 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
20886 New macros, so that the caller can use some names other than
20887 gcpro1, gcpro2, etc.
20888 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20890 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20891 argument, for consistency with GCPRO2_VAR, etc: it is now the
20892 prefix of the variable, not the variable itself. All uses
20894 * dired.c (directory_files_internal, file_name_completion):
20895 Rename locals to avoid shadowing.
20897 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20898 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20899 dired.c's scmp function, had undefined behavior.
20900 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20901 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20902 * buffer.h: ... to here, because these macros use current_buffer,
20903 and the new implementation with inline functions needs to have
20904 current_buffer in scope now, rather than later when the macros
20906 (downcase, upcase1): New static inline functions.
20907 (DOWNCASE, UPCASE1): Reimplement using these functions.
20908 This avoids undefined behavior in expressions like
20909 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20910 from race conditions in accessing the global variables
20911 case_temp1 and case_temp2.

20949 * buffer.c (fix_overlays_before): Mark locals as initialized.
20950 (fix_start_end_in_overlays): Likewise. This function should be
20951 simplified by using pointers-to-pointers, but that's a different

20954 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20955 (report_overlay_modification): Rename locals to avoid shadowing.

20960 to suppress a gcc -Wclobbered warning that does not seem to be right.
20961 (MAXPATHLEN): Define only if needed.
20963 * process.c (serial_open, serial_configure): Move decls from here ...
20964 * systty.h: ... to here, so that they can be checked.
20966 * fns.c (get_random, seed_random): Move extern decls from here ...
20967 * lisp.h: ... to here, so that they can be checked.
20969 * sysdep.c (reset_io): Now static.
20970 (wait_for_termination_signal): Remove; unused.
20972 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

20976 (DENSE_TABLE_SIZE): Remove; unused.
20977 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
20978 (describe_map_tree):
20979 Rename locals to avoid shadowing.
20981 * keyboard.c: Declare functions static if they are not used elsewhere.

21322 (decode_coding_emacs_mule): Mark variables that gcc
21323 -Wuninitialized does not deduce are never used uninitialized.
21324 (detect_coding_iso_2022): Initialize a local variable that might
21325 be used uninitialized. Leave a FIXME because it's not clear that
21326 this initialization is needed. (Bug#8211)
21327 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
21328 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):
