37 trailing dash is properly added.
39 2013-01-05 Eli Zaretskii <eliz@gnu.org>
41 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
42 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
43 digits for buffer positions, before misalignment starts.
44 Display "0" for integer "object" field.
45 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
46 Display the newline glyph more unambiguously.
48 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
50 * nsterm.m (ns_draw_underwave):
51 * w32term.c (w32_draw_underwave):
52 * xterm.c (x_draw_underwave): Make underwave look more triangular
53 and also degrade gracefully for small fonts. (Bug#13000)
55 * nsterm.m (ns_draw_text_decoration):
56 * w32term.c (x_draw_glyph_string):
57 * xterm.c (x_draw_glyph_string): Don't use previous underline

66 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
68 2013-01-02 Paul Eggert <eggert@cs.ucla.edu>
71 * dired.c (file_name_completion):

77 * minibuf.c (Ftry_completion):
78 * term.c (tty_ins_del_lines):
79 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
80 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
82 2012-12-31 Eli Zaretskii <eliz@gnu.org>
84 * w32.c (unsetenv): Set up the string passed to _putenv
86 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
87 for the bug this caused.
89 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
91 * coding.c (Qmac): Now static.
93 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
95 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
96 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
97 handlebox_widget. Set toolbar_in_hbox to false/true, set
98 toolbar_is_packed to true.
99 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
100 (update_frame_tool_bar): Check toolbar_is_packed for packing.
101 Show all on TOOLBAR_TOP_WIDGET.

104 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
105 Check toolbar_is_packed.
106 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
107 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
108 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
110 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
111 (xg_update_menubar): Update title only if
112 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
113 (xg_update_submenu): Skip tearoff only if

122 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
124 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
125 (LIBS_GNUSTEP): Define.
126 (LIBES): Add $(LIBS_GNUSTEP).

131 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
132 continuation glyph on a TTY with an indication of an empty line.
135 2012-12-29 Eli Zaretskii <eliz@gnu.org>
137 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if

140 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
142 * w32proc.c (reader_thread): Avoid passing NULL handles to
143 SetEvent and WaitForSingleObject.
145 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
147 Port EXTERNALLY_VISIBLE to Clang 3.2.
148 * conf_post.h (__has_attribute): New macro.
149 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
151 2012-12-27 Glenn Morris <rgm@gnu.org>
153 * cygw32.c (Fcygwin_convert_file_name_to_windows)

156 2012-12-27 Eli Zaretskii <eliz@gnu.org>
158 * fileio.c (file_name_as_directory, directory_file_name):
159 Accept an additional argument MULTIBYTE to indicate whether the input C
160 came from a multibyte or a unibyte Lisp string; all callers
161 adjusted. Don't assume the input string is always multibyte.
163 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
164 don't ENCODE_FILE them, and return a unibyte string if the input
166 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
167 don't assume the input strings will always be multibyte. If the
168 input strings are multibyte, decode strings obtained from C

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

178 * alloc.c (valid_lisp_object_p): Adjust comment.
180 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
182 * keyboard.c (record_asynch_buffer_change): Initialize an event
183 only if it's really needed.
184 * frame.h (enum output_method): Remove output_mac member since
185 it's a leftover from the deleted code.
186 * frame.c (Fframep): Adjust user here ...
187 * terminal.c (Fterminal_live_p): ... and here.
188 * coding.c (Qmac): Now here because it's only used to denote
189 end-of-line encoding type.
190 (syms_of_coding): DEFSYM it.
191 * frame.h (Qmac): Remove duplicated declaration.
193 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
195 * window.c (select_window_1): Now static, since it's used only here.
197 2012-12-25 Eli Zaretskii <eliz@gnu.org>
199 * window.c (window_body_cols): Subtract display margins from the
200 window body width on TTYs as well. See
201 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
202 for the original report.
204 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
206 * xdisp.c (redisplay_window): Remove inner local variable
207 because the outer shadowed one has the same meaning.
208 * xterm.h (struct x_output): Remove toolbar_detached member since it's
210 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
211 (xg_create_tool_bar): Adjust users.
213 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
215 * buffer.h (BUF_COMPACT): New macro to follow the common style.
216 * buffer.c (Fget_buffer_create): Use it to set compact field of
217 struct buffer_text to avoid accessing an uninitialized value
218 when compact_buffer is called for the first time.
219 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
220 (Fset_buffer_modified_p): Use buffer_window_count to check
221 whether the buffer is displayed in some window.
222 * xdisp.c (message_dolog): Likewise.
224 2012-12-23 Eli Zaretskii <eliz@gnu.org>
226 * w32.c (acl_set_file): If setting the file security descriptor
227 fails, and the new DACL is identical to the existing one, silently
228 return success. This fixes problems for users backing up their
229 own files without having the necessary privileges for setting
230 security descriptors.
232 * w32proc.c (reader_thread): Do not index fd_info[] with negative
234 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
235 after WaitForSingleObject returns normally. This expedites reader
236 thread shutdown when delete_child triggers it.
237 (reap_subprocess): More accurate commentary for why we call
238 delete_child only when cp->fd is negative.
240 * w32.c (sys_close): Do not call delete_child on a subprocess
241 whose handle is not yet closed. Instead, set its file descriptor
242 to a negative value, so that reap_subprocess will call
243 delete_child on that subprocess when its SIGCHLD arrives.
244 This avoids closing handles used for communications between sys_select
245 and reader_thread, which doesn't give sys_select a chance to
246 notice that the process exited and invoke the SIGCHLD handler for
249 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
251 * nsfns.m (Fns_do_applescript): Run event loop until script has
252 been executed (Bug#12969).
253 (ns_run_ascript): Chech as_script for nil, set to nil after
256 2012-12-22 Martin Rudalics <rudalics@gmx.at>
258 * window.c (Fselect_window): Reword doc-string (Bug#13248).
260 2012-12-22 Eli Zaretskii <eliz@gnu.org>
262 * w32term.c (w32fullscreen_hook): New function.
263 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
265 2012-12-21 Eli Zaretskii <eliz@gnu.org>
267 * fileio.c (Finsert_file_contents): Doc fix.
269 * w32proc.c (new_child, delete_child, find_child_pid): For a
270 subprocess, consider its slot being in use as long as its process
271 handle (procinfo.hProcess) is not NULL. This avoids reusing the
272 slot when a new process is started immediately after killing
273 another one, without waiting enough time for the first process to
274 be reaped and resources allocated for it be orderly freed.
276 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
278 2012-12-21 Chong Yidong <cyd@gnu.org>
280 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
282 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
284 2012-12-21 Eli Zaretskii <eliz@gnu.org>
286 * w32.c (get_name_and_id): Always pass NULL as the first argument
287 of lookup_account_sid. Avoids crashes with UNC file names that
288 refer to DFS domains, not to specific machine names. (Bug#12621)
289 Remove now unused argument FNAME; all callers changed.
290 (get_file_owner_and_group): Remove now unused argument FNAME; all
293 2012-12-21 Chong Yidong <cyd@gnu.org>
295 * editfns.c (Finsert_char): Since read-char-by-name now signals an
296 error for invalid chars, don't check for a nil return value.
298 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
300 Avoid calls to CHAR_TO_BYTE if byte position is known.
301 * editfns.c (make_buffer_string_both): Use move_gap_both.
302 (Fbuffer_string): Use make_buffer_string_both.
303 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
305 (buf_bytepos_to_charpos): Likewise.
306 (charpos_to_bytepos): Remove.
307 * fileio.c (Finsert_file_contents): Use move_gap_both.
308 * search.c (Freplace_match): Likewise.
309 * process.c (process_send_region): Likewise. Use convenient
310 names for byte positions.
311 * lisp.h (charpos_to_bytepos): Remove prototype.
312 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
313 * insdel.c (move_gap): Likewise.
315 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
317 * xdisp.c (redisplay_internal): Remove now-unused local.
319 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
321 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
322 (redisplay_internal): Don't bother selecting the frame to get the
323 proper value of frame-local variables (bug#13225).
325 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
327 * textprop.c (set_text_properties_1): Do not allow NULL interval.
328 Rename 4th argument since it may be buffer or string. Adjust comment.
329 * intervals.c (graft_intervals_info_buffer): Find an interval here.
331 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
333 * coding.c (Fdetect_coding_region): Do not check start and end with
334 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
335 (code_convert_region): Likewise.
337 2012-12-18 Eli Zaretskii <eliz@gnu.org>
339 * w32.c (acl_get_file, acl_set_file): Run the file name through
340 map_w32_filename, and resolve any symlinks in the file name, like
342 (acl_set_file): Call revert_to_self, if any privileges were
345 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
347 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
348 ($(BLD)/w32.$(O)): Update dependencies.
350 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
352 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
353 propagate redisplay's scrolling (if any) to the right window.
354 (redisplay_internal): Use ensure_selected_frame.
355 (display_mode_lines): Complete last fix.
356 * window.c (select_window_1): New func, extracted from select_window.
357 (select_window): Use it.
358 * window.h (select_window_1): Declare.
360 2012-12-17 Eli Zaretskii <eliz@gnu.org>

363 * w32.c: Include sddl.h and sys/acl.h.
364 (SDDL_REVISION_1): Define if not already defined.

382 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
384 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
386 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
387 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
388 for some of that bug's symptoms can now cause Emacs to abort.
389 Remove the workaround.
390 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
391 The bug that caused SIGCHLD to get lost has been fixed, and the
392 workaround for it can now cause Emacs to abort.
394 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
396 * sysdep.c (emacs_abort): Bump backtrace size to 40.
397 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
398 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
400 2012-12-16 Romain Francoise <romain@orebokech.com>
402 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
403 (Fcopy_file): Change last arg to `preserve_extended_attributes'
404 and copy ACL entries of file in addition to SELinux context if set.
405 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
407 * Makefile.in (LIBACL_LIBS): New macro.
410 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
412 * fileio.c (internal_delete_file): Use bool for boolean.
414 2012-12-15 Eli Zaretskii <eliz@gnu.org>
416 Fix bug #13079 on MS-Windows with temp files not being deleted.

419 (register_child): First argument is now pid_t.
420 (record_infile, record_pending_deletion): New prototypes.
422 * w32proc.c (new_child): Initialize input_file and
423 pending_deletion members of the child.
424 (delete_child): Delete the child's temporary input file, if any,
425 that is pending deletion.
426 (register_child): First argument is now pid_t.
427 (record_infile, record_pending_deletion): New functions.
428 (reap_subprocess): Fix a typo in DebPrint string.
429 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
431 * fileio.c (internal_delete_file): Return an int again: non-zero
432 if delete-file succeeds, zero otherwise.
434 * lisp.h (internal_delete_file): Adjust prototype.
436 * callproc.c (Fcall_process): Don't overwrite infile with result
438 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
439 asynchronous subprocess, record the name of the input file name,
441 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
442 delete the file, record it as pending deletion when the subprocess
445 2012-12-14 Eli Zaretskii <eliz@gnu.org>
447 * editfns.c [HAVE_PWD_H]: Include grp.h.
449 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
451 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
453 Fix permissions bugs with setgid directories etc. (Bug#13125)
454 * dired.c (Ffile_attributes): Return t as the 9th attribute,
455 to mark it as a placeholder. The old value was often wrong.
456 The only user of this attribute has been changed to use
457 file-ownership-preserved-p instead, with its new group arg.
458 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
460 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

465 2012-12-14 Eli Zaretskii <eliz@gnu.org>
467 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
468 try to get accurate owner and group information from NT file
469 security APIs. This is to make most callers of 'stat' and
470 'lstat', which don't need that information, much faster.
472 * dired.c (Ffile_attributes) [WINDOWSNT]:
473 Set w32_stat_get_owner_group to a non-zero value, to request accurate
474 owner and group information from 'lstat'.
476 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
478 * fileio.c (Finsert_file_contents): Don't put tail into head area,
479 as that confuses set-auto-coding, so insist on the head-read
480 returning the full 1024 bytes. Let lseek compute the tail offset;
481 less work for us. Do not ignore I/O errors when reading the tail.
483 * xdisp.c: Minor style fixes.
484 (init_iterator): Hoist assignment out of if-expression.
485 (markpos_of_region): Callers now test for sign, not for -1.
487 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
489 Minor redisplay optimization when the region length is zero.
490 * xdisp.c (markpos_of_region): New function.
491 (init_iterator): Do not highlight the region of zero length.
492 (redisplay_window): Check whether the region is of non-zero length.
493 (try_cursor_movement): Allow if the region length is zero.
494 (try_window_reusing_current_matrix, try_window_id): Likewise.
496 2012-12-13 Eli Zaretskii <eliz@gnu.org>
498 * search.c (search_buffer): Check the inverse translations of each
499 character in pattern when the buffer being searched is unibyte.
502 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>

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

545 (append_stretch_glyph, append_glyphless_glyph): Reverse the
546 left_box_line_p and right_box_line_p flags of the glyph for R2L
547 glyph rows. (Bug#13011)

597 (hinst): Remove unneeded extern declaration.
598 (_start): Remove initialization of above variables; remove
599 initialization of hinst, as cache_system_info now does that.

633 and this is a TTY frame, signal the caller that keyboard input is
636 * w32xfns.c (drain_message_queue): Now returns an int: an
637 indication whether any WM_EMACS_FILENOTIFY messages were found in

741 * w32.c (unsetenv): Return 0 if the input string is too long.
743 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>

760 no longer needed here.
761 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
762 Move to inside set_time_zone_rule; they don't need file scope any more.
763 (set_time_zone_rule): Maintain the TZ=value string separately.
764 (syms_of_editfns): Don't initialize initial_tz;
765 init_editfns now does it.
766 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
767 * lisp.h (xputenv): New decl.
769 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

790 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
791 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.

794 (record_child_status_change, handle_child_signal, deliver_child_signal)

813 This will cause a production Emacs to dump core instead of
816 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
818 * frame.c (make_frame): Do not set window's buffer to t.
819 * window.c (Fsplit_window_internal): Likewise. Previously it was
820 used to indicate that the window is being set up. Now we use
821 set_window_buffer for all new windows, so the condition in ...
822 (Fset_window_buffer): ... is always true and can be removed.
824 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
826 Convenient macro to check whether the buffer is hidden.
827 * buffer.h (BUFFER_HIDDEN_P): New macro.

834 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
835 if the child process is still running. Instead, exit the wait
836 loop and return zero. (Bug#13086)
838 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
840 * frame.h (x_char_width, x_char_height): Remove prototypes.

849 (command_loop_2, top_level_1): Add static to match prototype.
851 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
853 Fix a recently-introduced delete-process race condition.
854 * callproc.c, process.h (record_kill_process):
855 New function, containing part of the old call_process_kill.
856 (call_process_kill): Use it.
857 This does not change call_process_kill's behavior.
858 * process.c (Fdelete_process): Use record_kill_process to fix a
859 race condition that could cause Emacs to lose track of a child.
861 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
863 Avoid code duplication between prev_frame and next_frame.
864 * frame.c (candidate_frame): New function. Add comment.
865 (prev_frame, next_frame): Use it. Adjust comment.
867 2012-12-06 Eli Zaretskii <eliz@gnu.org>
869 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
870 fails, signal an error instead of continuing with an empty
872 Encode expanded temp file pattern before passing it to mkstemp or
875 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
876 Encode the file name before passing it to dostounix_filename, in
877 case it will downcase it (under w32-downcase-file-names).
880 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
882 Minor call-process cleanups.
883 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
884 at the same time as other platforms, to simplify analysis.
885 No need for fd0_volatile since we have synch_process_fd.
886 Avoid needless emacs_close; arg is always negative.
888 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
890 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
893 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
895 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
896 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
897 and mouse_face_hidden members to a bitfields.
898 * frame.h (struct frame): Remove set-but-not-used space_width member.
899 (FRAME_SPACE_WIDTH): Remove.
900 * nsterm.m, w32term.c, xterm.c: Adjust users.
901 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
902 member. Adjust users. Convert term_initted, delete_in_insert_mode,
903 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
904 members to a bitfields.
906 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
908 Don't let call-process be a zombie factory (Bug#12980).
909 Fixing this bug required some cleanup of the signal-handling code.
910 As a side effect, this change also fixes a longstanding rare race
911 condition whereby Emacs could mistakenly kill unrelated processes,
912 and it fixes a bug where a second C-g does not kill a recalcitrant
913 synchronous process in GNU/Linux and similar platforms.
914 The patch should also fix the last vestiges of Bug#9488,
915 a bug which has mostly been fixed on the trunk by other changes.
916 * callproc.c, process.h (synch_process_alive, synch_process_death)
917 (synch_process_termsig, sync_process_retcode):
918 Remove. All uses removed, to simplify analysis and so that
919 less consing is done inside critical sections.
920 * callproc.c (call_process_exited): Remove. All uses replaced
921 with !synch_process_pid.
922 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
923 These take the role of what used to be in unwind-protect arg.
925 (block_child_signal, unblock_child_signal):
926 New functions, to avoid races that could kill innocent-victim processes.
927 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
928 (call_process_kill): Record killed processes as deleted, so that
929 zombies do not clutter up the system. Do this inside a critical
930 section, to avoid a race that would allow the clutter.
931 (call_process_cleanup): Fix code so that the second C-g works again
932 on common platforms such as GNU/Linux.
933 (Fcall_process): Create the child process in a critical section,
934 to fix a race condition. If creating an asynchronous process,
935 record it as deleted so that zombies do not clutter up the system.
936 Do unwind-protect for WINDOWSNT too, as that's simpler in the
937 light of these changes. Omit unnecessary call to emacs_close
938 before failure, as the unwind-protect code does that.
939 * callproc.c (call_process_cleanup):
940 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
941 * process.c (record_deleted_pid): New function, containing
942 code refactored out of Fdelete_process.
943 (Fdelete_process): Use it.
944 (process_status_retrieved): Remove. All callers changed to use
946 (record_child_status_change): Remove, folding its contents into ...
947 (handle_child_signal): ... this signal handler. Now, this
948 function is purely a handler for SIGCHLD, and is not called after
949 a synchronous waitpid returns; the synchronous code is moved to
950 wait_for_termination. There is no need to worry about reaping
951 more than one child now.
952 * sysdep.c (get_child_status, child_status_changed): New functions.
953 (wait_for_termination): Now takes int * status and bool
954 interruptible arguments, too. Do not record child status change;
955 that's now the caller's responsibility. All callers changed.
956 Reimplement in terms of get_child_status.
957 (wait_for_termination_1, interruptible_wait_for_termination):
958 Remove. All callers changed to use wait_for_termination.
959 * syswait.h: Include <stdbool.h>, for bool.
960 (record_child_status_change, interruptible_wait_for_termination):
962 (record_deleted_pid, child_status_changed): New decls.
963 (wait_for_termination): Adjust to API changes noted above.
965 * bytecode.c, lisp.h (Qbytecode): Remove.
966 No longer needed after 2012-11-20 interactive-p changes.
968 2012-12-03 Eli Zaretskii <eliz@gnu.org>
970 * xdisp.c (redisplay_window): If the cursor is visible, but inside
971 the scroll margin, move point outside the margin. (Bug#13055)
973 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
975 * gtkutil.c (my_log_handler): New function.
976 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
978 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
980 * lisp.h (modify_region): Rename to...
981 (modify_region_1): ...new prototype.
982 * textprop.c (modify_region): Now static. Adjust users.
983 * insdel.c (modify_region): Rename to...
984 (modify_region_1): ...new function to work with current buffer.
985 Adjust comment and users. Use true and false for booleans.
987 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
989 * alloc.c (free_save_value): New function.
990 (safe_alloca_unwind): Use it.

992 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
994 (save_excursion_restore): Adjust to match saved data structure.
995 Use free_save_value to offload some work from GC. Drop obsolete
998 2012-12-03 Chong Yidong <cyd@gnu.org>

1022 Fix xpalloc confusion after memory is exhausted.
1023 * alloc.c (xpalloc): Comment fix.
1024 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
1025 and signals an error, do not clear charset_table_size, as
1026 charset_table is still valid.
1027 * doprnt.c (evxprintf): Clear *BUF after freeing it.
1029 Use execve to avoid need to munge environ (Bug#13054).
1030 * callproc.c (Fcall_process):
1031 * process.c (create_process):
1032 Don't save and restore environ; no longer needed.
1033 * callproc.c (child_setup):
1034 Use execve, not execvp, to preserve environ.
1036 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
1038 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
1040 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1042 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
1043 display for sliced images (Bug#10500).
1045 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.

1050 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
1052 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
1054 * xdisp.c (window_outdated): Remove eassert since it hits
1055 some suspicious corner cases (see Bug#13007 and Bug#13012).
1056 (mode_line_update_needed): New function.
1057 (redisplay_internal, redisplay_window): Use it.
1058 (ensure_selected_frame): New function.
1059 (redisplay_internal, unwind_redisplay): Use it.
1060 (redisplay_internal): Move comment about buffer_shared...
1061 (buffer_shared_and_changed): ...near to its real use.
1063 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
1065 * callproc.c (Fcall_process): Don't misreport vfork failure.
1067 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
1069 * callproc.c (Fcall_process): Fix vfork portability problems.
1070 Do not assume that fd[0], count, filefd, and save_environ survive
1071 vfork. Fix bug whereby wrong errno value could be reported for
1072 pipe failure. Some minor cleanups, too, as follows. Move buf and
1073 bufsize to the context where they're needed. Change new_argv to
1074 be of type char **, as this is more convenient and avoids casts.
1075 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
1076 Now local constants, not macros.
1078 2012-11-18 Kenichi Handa <handa@gnu.org>
1080 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
1081 for the variable "f".
1083 2012-11-13 Kenichi Handa <handa@gnu.org>
1085 * font.c (font_unparse_xlfd): Exclude special characters from the
1086 generating XLFD name.
1088 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

1092 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
1094 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

1113 violations when repeatedly clicking on the "Top" link of the
1114 "bread-crumbs" in Info buffers.

1124 were always defined.
1126 2012-11-24 Eli Zaretskii <eliz@gnu.org>
1128 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
1129 between bpos_covered and bpos_max. This fixes cursor display when
1130 several display strings follow each other.
1132 * .gdbinit (pgx): If the glyph's object is a string, display the
1133 pointer to string data, rather than the value of the string object
1134 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
1136 * indent.c (Fvertical_motion): If the starting position is covered
1137 by a display string, return to one position before that, to avoid
1138 overshooting it inside move_it_to. (Bug#12930)
1140 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
1142 * frame.h (struct frame): Remove display_preempted member

1145 * w32menu.c (pending_menu_activation): Remove since not
1147 (set_frame_menubar): Adjust user.
1148 * w32term.h (struct x_output): Drop outdated #if 0 code.

1151 Drop unused pending_menu_activation member.
1152 * xterm.h (struct x_output): Drop outdated #if 0 code.
1153 Use bitfields for explicit_parent, asked_for_visible,
1154 has_been_visible and net_wm_state_hidden_seen members.
1156 2012-11-23 Eli Zaretskii <eliz@gnu.org>
1158 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
1159 of a literal "/". (Bug#12955)
1160 (gl-stamp): Invoke fc.exe directly, not through cmd.

1165 * dired.c: Assume HAVE_DIRENT_H.
1166 (NAMLEN): Remove, replacing with ...
1167 (dirent_namelen): New function. All uses changed. Use the GNU macro
1168 _D_EXACT_NAMELEN if available, as it's faster than strlen.
1169 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
1170 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
1171 * makefile.w32-in (DIR_H): Remove. All uses replaced with
1173 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
1174 * ndir.h: Rename to ../nt/inc/dirent.h.
1175 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
1176 Do not include <dirent.h>; no longer needed.
1177 * w32.c: Include <dirent.h> rather than "ndir.h".
1179 2012-11-23 Chong Yidong <cyd@gnu.org>
1181 * xftfont.c (xftfont_open): Remove duplicate assignment.
1183 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1185 * alloc.c (Fgarbage_collect): Unblock input after clearing
1186 gc_in_progress to avoid note_mouse_highlight glitch with GC.
1187 * frame.h (FRAME_MOUSE_UPDATE): New macro.
1188 * msdos.c (IT_frame_up_to_date): Use it here...
1189 * w32term.c (w32_frame_up_to_date): ...here...
1190 * xterm.c (XTframe_up_to_date): ...and here...
1191 * nsterm.m (ns_frame_up_to_date): ...but not here.
1192 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
1194 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
1195 Do not check whether GC is in progress.
1197 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
1199 * xdisp.c (window_buffer_changed): New function.
1200 (update_menu_bar, update_tool_bar): Use it to
1201 simplify large 'if' statements.
1202 (redisplay_internal): Generalize commonly used
1203 'tail' and 'frame' local variables.
1205 2012-11-22 Eli Zaretskii <eliz@gnu.org>
1207 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
1208 with Windows system header.
1210 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
1212 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
1213 * alloc.c: Assume unistd.h exists.
1214 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
1215 * sysdep.c (get_current_dir_name): Assume getcwd exists.
1216 (getwd) [USG]: Remove; no longer needed.
1217 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
1218 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
1219 * w32.h (getcwd): Remove decl.
1221 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>

1229 * emacs.c (main): Set the G_SLICE environment variable for all
1230 Cygwin builds, not just GTK builds. See
1231 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
1233 2012-11-21 Eli Zaretskii <eliz@gnu.org>
1235 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
1236 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
1237 Define for the MSVC compiler.
1239 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
1241 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
1242 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
1243 dostounix_filename. Prevents crashes down the road, because
1244 dostounix_filename assumes it gets a unibyte string.
1245 Reported by Michel de Ruiter <michel@sentient.nl>, see

1265 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
1267 * xdisp.c (buffer_shared): Adjust comment.
1268 (buffer_shared_and_changed): New function.
1269 (prepare_menu_bars, redisplay_internal): Use it to
1270 decide whether all windows or frames should be updated.
1271 (window_outdated): New function.
1272 (text_outside_line_unchanged_p, redisplay_window): Use it.
1273 (redisplay_internal): Likewise. Fix indentation.
1275 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
1277 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
1278 (syms_of_eval): Remove corresponding defsubr.
1279 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
1281 2012-11-19 Daniel Colascione <dancol@dancol.org>
1283 * w32fns.c (Fx_file_dialog):
1284 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
1285 cygwin_convert_file_name*.
1287 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
1288 Rename cygwin_convert_path* to cygwin_convert_file_name*.
1290 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
1292 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
1294 2012-11-18 Eli Zaretskii <eliz@gnu.org>
1296 * w32select.c: Include w32common.h before w32term.h, so that
1297 windows.h gets included before w32term.h uses some of its
1298 features, see below.
1300 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
1302 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
1304 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
1306 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
1308 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
1309 (ns_select): Return at once if events are held (Bug#12834).
1311 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
1313 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
1314 Needed following 2012-10-20 change. (Bug#12902)
1316 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
1318 * w32proc.c (waitpid): Remove unused label get_result.
1320 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
1322 * makefile.w32-in (SYSWAIT_H): New macro.
1323 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
1324 ($(BLD)/sysdep.$(O)): Update dependencies.
1326 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1328 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
1329 * callproc.c (relocate_fd): Assume F_DUPFD.
1330 * emacs.c, term.c (O_RDWR): Remove.
1331 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
1332 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
1333 * nsterm.m: Assume <fcntl.h> exists.
1334 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
1335 (create_pty, Fmake_network_process, server_accept_connection)
1336 (wait_reading_process_output, init_process_emacs):
1338 (wait_reading_process_output): Put in a special case for WINDOWSNT
1339 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
1340 It's not clear this is needed, but it's a more-conservative change.
1341 (create_process): Assume FD_CLOEXEC.
1342 (create_process, create_pty): Assume O_NOCTTY.
1343 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
1344 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
1345 Omit if not DOS_NT, since F_GETFL is not defined there.
1346 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
1347 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
1349 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
1350 lack it, since gnulib guarantees this.
1351 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
1353 2012-11-17 Eli Zaretskii <eliz@gnu.org>
1355 * w32.c (faccessat): Pretend that directories have the execute bit
1356 set. Emacs expects that, e.g., in files.el:cd-absolute.
1358 * w32proc.c (create_child): Don't clip the PID of the child
1359 process to fit into an Emacs integer, as this is no longer a
1361 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
1362 reaping only the process specified by PID argument, if that is
1363 positive. Use PID instead of dead_child to know which process to
1364 reap. Wait for the child to die only if WNOHANG is not in
1366 (sys_select): Don't set dead_child.
1368 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
1369 as it is no longer needed.
1371 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
1373 (record_child_status_change): Remove the setting of
1374 record_at_most_one_child for the !WNOHANG case.
1376 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
1378 Fix problems in ns port found by static checking.
1379 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
1380 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
1381 not to process group.
1382 (ns_select): Use emacs_write, not write, as that's more robust
1383 in the presence of signals.
1384 (fd_handler:): Check for read errors.
1386 2012-11-16 Glenn Morris <rgm@gnu.org>
1388 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
1390 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
1392 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
1394 2012-11-16 Eli Zaretskii <eliz@gnu.org>
1396 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
1397 use the same value of thread handle.
1398 (start_timer_thread): If the timer thread exited (due to error),
1399 clean up by closing the two handles it used. Duplicate the caller
1400 thread's handle here, so it gets duplicated only once, when
1401 launching the timer thread. Set priority of the timer thread, not
1403 (getitimer): Don't duplicate the caller thread's handle here.
1406 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
1408 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
1411 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
1413 Remove no-longer-used pty_max_bytes variable.
1414 * process.c (pty_max_bytes): Remove; unused.
1415 (send_process): Do not set it.
1417 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
1419 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
1420 Update dependencies.
1422 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
1424 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
1425 This follows up on the 2012-09-29 patch that removed indirection
1426 for the 'function' field. Reported by Sergey Vinokurov in
1427 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
1429 2012-11-14 Eli Zaretskii <eliz@gnu.org>
1431 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
1432 different name, as the MS runtime does not have such a function,
1433 and probably never will.) All callers changed. Ignore DIRFD
1434 value if PATH is an absolute file name, to match Posix spec
1435 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
1438 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
1440 * xdisp.c (echo_area_display, redisplay_internal):
1441 Omit redundant check whether frame_garbaged is set.
1443 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
1445 Use faccessat, not access, when checking file permissions (Bug#12632).
1446 This fixes a bug that has been present in Emacs since its creation.
1447 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
1448 which must set some sort of record. (Torek's bug report was against
1449 a predecessor of GNU Emacs, but GNU Emacs happened to have the
1450 same common flaw.) See Torek's Usenet posting
1451 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
1452 Posted: Fri Apr 8 14:18:56 1983.
1453 * Makefile.in (LIB_EACCESS): New macro.
1455 * callproc.c (init_callproc):
1456 * charset.c (init_charset):
1457 * fileio.c (check_existing, check_executable, check_writable)
1459 * lread.c (openp, load_path_check):
1460 * process.c (allocate_pty):
1462 Use effective UID when checking permissions, not real UID.
1463 * callproc.c (init_callproc):
1464 * charset.c (init_charset):
1465 * lread.c (load_path_check, init_lread):
1466 Test whether directories are accessible, not merely whether they exist.
1467 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
1468 * fileio.c (check_existing, check_executable, check_writable)
1470 Use symbolic names instead of integers for the flags, as they're
1472 (check_writable): New arg AMODE. All uses changed.
1473 Set errno on failure.
1474 (Ffile_readable_p): Use faccessat, not stat + open + close.
1475 (Ffile_writable_p): No need to call check_existing + check_writable.
1476 Just call check_writable and then look at errno. This saves a syscall.
1477 dir should never be nil; replace an unnecessary runtime check
1478 with an eassert. When checking the parent directory of a nonexistent
1479 file, check that the directory is searchable as well as writable, as
1480 we can't create files in unsearchable directories.
1481 (file_directory_p): New function, which uses 'stat' on most platforms
1482 but faccessat with D_OK (for efficiency) if WINDOWSNT.
1483 (Ffile_directory_p, Fset_file_times): Use it.
1484 (file_accessible_directory_p): New function, which uses a single
1485 syscall for efficiency.
1486 (Ffile_accessible_directory_p): Use it.
1487 * xrdb.c (file_p): Use file_directory_p.
1488 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
1489 * lread.c (openp): When opening a file, use fstat rather than
1490 stat, as that avoids a permissions race. When not opening a file,
1491 use file_directory_p rather than stat.
1492 (dir_warning): First arg is now a usage string, not a format.
1493 Use errno. All uses changed.
1494 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
1495 that merely introduced a race.
1496 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
1497 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
1498 and similarly for the other O_* flags.
1499 * w32.c (sys_faccessat): Rename from sys_access and switch to
1500 faccessat's API. All uses changed.
1501 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
1502 (magic_db): Rename from magic_file_p.
1503 (magic_db, search_magic_path): Return an XrmDatabase rather than a
1504 char *, so that we don't have to test for file existence
1505 separately from opening the file for reading. This removes a race
1506 fixes a permission-checking problem, and simplifies the code.
1508 (file_p): Remove; no longer needed.
1510 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
1512 Omit glyphs initialization at startup.
1513 * dispnew.c (glyphs_initialized_initially_p): Remove.
1514 (adjust_frame_glyphs_initially): Likewise. Adjust users.
1515 (Fredraw_frame): Move actual code from here...
1516 (redraw_frame): ...to here. Add eassert. Adjust comment.
1517 (Fredraw_display): Use redraw_frame.
1518 * xdisp.c (clear_garbaged_frames): Likewise.
1520 2012-11-13 Eli Zaretskii <eliz@gnu.org>
1522 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
1523 passed to pint2str and pint2hrstr to be at most the size of the
1524 frame's decode_mode_spec_buffer. This avoids crashes with very
1525 large values of FIELD_WIDTH argument to decode_mode_spec.
1528 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
1530 Fix a race with verify-visited-file-modtime (Bug#12863).
1531 Since at least 1991 Emacs has ignored an mtime difference of no
1532 more than one second, but my guess is that this was to work around
1533 file system bugs that were fixed long ago. Since the race is
1534 causing problems now, let's remove that code.
1535 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
1536 whose time stamp is off by no more than a second. Insist that the
1537 file time stamps match exactly.
1539 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1541 * frame.h (struct frame): Convert external_tool_bar member to
1542 1-bit unsigned bitfield.
1543 * termhooks.h (struct terminal): Remove mouse_moved member since
1544 all users are long dead. Adjust comment on mouse_position_hook.
1546 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
1548 Simplify by using FOR_EACH_FRAME here and there.
1549 * frame.c (next_frame, prev_frame, other_visible_frames)
1550 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
1551 * w32term.c (x_window_to_scroll_bar): Likewise.
1552 * window.c (window_list): Likewise.
1553 * xdisp.c (x_consider_frame_title): Likewise.
1554 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
1555 * xfns.c (x_window_to_frame, x_any_window_to_frame)
1556 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
1557 * xmenu.c (menubar_id_to_frame): Likewise.
1558 * xselect.c (frame_for_x_selection): Likewise.
1559 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
1560 (x_window_to_menu_bar): Likewise.
1561 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
1563 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
1565 * data.c (Qdefalias_fset_function): Now static.
1567 Another tweak to vectorlike_header change.

1569 Remove, and replace all uses with ...
1570 (next_in_free_list, set_next_in_free_list):
1571 New functions, which respect C's aliasing rules better.
1573 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
1575 * window.c (list4i): Rename from 'quad'. All uses changed.
1576 Needed because <sys/types.h> defines 'quad' on Solaris 10.
1578 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
1580 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
1581 warning about mixing declarations and code in ISO C90.
1583 2012-11-10 Martin Rudalics <rudalics@gmx.at>
1585 * window.c (Fsplit_window_internal): Set combination limit of
1586 new parent window to t iff Vwindow_combination_limit is t;
1587 fixing a regression introduced with the change from 2012-09-22.
1588 (Fset_window_combination_limit): Fix doc-string.
1590 2012-11-10 Eli Zaretskii <eliz@gnu.org>
1592 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
1593 amount when the scroll margins are too large. When scrolling
1594 backwards in the buffer, give up if cannot reach point or the
1595 scroll margin within a reasonable number of screen lines.
1596 Fixes point position in window under scroll-up/down-aggressively when
1597 point is positioned many lines beyond the window top/bottom.
1600 * ralloc.c (relinquish): If real_morecore fails to return memory
1601 to the system, don't crash; instead, leave the last heap
1602 unchanged and return. (Bug#12774)
1604 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1606 * lisp.h (AUTOLOADP): New macro.

1609 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
1611 (Finteractive_form): Simplify.
1612 (Fquo): Don't insist on having at least 2 arguments.
1613 (Qdefalias_fset_function): New var.
1615 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>

1623 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1625 Fix recently introduced crash on MS-Windows (Bug#12839).
1626 * w32term.h (struct scroll_bar): Use convenient header.
1627 (SCROLL_BAR_VEC_SIZE): Remove.
1628 * w32term.c (x_scroll_bar_create): Use VECSIZE.
1630 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
1632 Tweak last vectorlike_header change.
1633 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
1634 vectorlike object on the free list. This is introduced to avoid
1635 some (but not all) pointer casting and aliasing problems, see
1636 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
1637 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

1641 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
1643 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
1644 been removed, so remove them here also.
1646 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
1648 * doc.c (Fdocumentation): Handle new property
1649 dynamic-docstring-function to replace the old ad-advice-info.
1651 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>

1655 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
1657 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
1658 * fns.c (hashfn_eq, hashfn_eql, sxhash):
1659 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

1673 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
1674 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
1675 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
1678 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
1680 * image.c (xpm_make_color_table_h): Fix compiler error because

1690 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
1691 (make_log): Use them.

1742 (Fmake_bool_vector): Likewise.
1743 (struct large_vector): New type to represent allocation unit for
1744 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
1745 (large_vectors): Change type to struct large_vector.
1746 (allocate_vector_from_block): Simplify.

1774 2012-11-07 Eli Zaretskii <eliz@gnu.org>
1776 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
1777 such as Scroll Lock, if the respective keys are treated as
1778 function keys, not as modifiers. This avoids destroying non-ASCII
1779 keyboard input when Scroll Lock is toggled ON. (Bug#12806)

1785 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1787 Restore some duplicate definitions (Bug#12814).
1788 This undoes part of the 2012-11-03 changes. Some people build
1789 with plain -g rather than with -g3, and they need the duplicate
1790 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
1791 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
1792 Define as macros, as well as as enums or as constants.

1797 to keypad keys (Bug#12816).
1799 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
1801 Minor adjustments of recently-changed frame functions.
1802 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
1803 known to be a frame (we're in the FRAMEP branch).
1804 * lisp.h (Qframep): Remove decl. frame.h declares this.
1805 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
1806 since they're meant for Lisp fixnum values.
1808 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
1810 * window.c (Fwindow_combination_limit): Revert to the only
1811 required argument and adjust docstring as suggested in
1812 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
1813 by Martin Rudalics <rudalics@gmx.at>.

1868 file descriptor 2 for standard error. (Bug#12805)
1870 2012-11-05 Chong Yidong <cyd@gnu.org>
1872 * process.c (wait_reading_process_output): Revert previous change.
1874 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
1876 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).

1878 * callproc.c (Fcall_process):
1880 * process.c (create_process):
1881 * term.c (dissociate_if_controlling_tty):

1884 per POSIX.1-1988 or later.
1885 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
1886 * emacs.c (shut_down_emacs):
1887 * sysdep.c (sys_suspend, init_foreground_group):
1888 Assume getpgrp behaves as per POSIX.1-1998 or later.
1889 * msdos.c (setpgrp): Remove.
1890 (tcgetpgrp, setpgid, setsid): New functions.
1891 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
1892 * term.c (no_controlling_tty): Remove; unused.
1893 * w32proc.c (setpgrp): Remove.
1894 (setsid, tcgetpgrp): New functions.
1896 Simplify by assuming __fpending.
1897 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
1898 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
1899 Do not assume that __fpending's result fits in int.
1901 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
1903 Remove EMACS_OUTQSIZE+sleep hack.
1904 * dispnew.c (update_frame_1): Remove hack for terminals slower
1905 than 2400 bps, which throttled Emacs by having it sleep.
1906 This code hasn't worked since at least 2007, when the multi-tty stuff
1907 was added, and anyway those old terminals are long dead.
1908 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
1909 without the dispnew.c change, as dispnew.c doesn't include systty.h.
1911 Fix data-loss with --version (Bug#9574).
1912 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
1913 as we can't assume that emacs_strerror is initialized, and strerror
1914 is good enough here.
1915 (main): Invoke atexit earlier, to catch earlier instances of
1916 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
1918 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
1920 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
1921 (keyDown): Remap keypad keys to X11 virtual key codes.
1923 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
1925 Fix data-loss with --batch (Bug#9574).
1926 * emacs.c: Include <close-stream.h>.
1927 (close_output_streams): New function.
1928 (main): Pass it to atexit, so that Emacs closes stdout and stderr
1929 and handles errors appropriately.
1930 (Fkill_emacs): Don't worry about flushing, as close_output_stream
1933 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
1934 The symptom is a diagnostic "GLib-WARNING **: In call to
1935 g_spawn_sync(), exit status of a child process was requested but
1936 SIGCHLD action was set to SIG_IGN and ECHILD was received by
1937 waitpid(), so exit status can't be returned." The diagnostic
1938 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
1939 The real bug is a race condition between Emacs and glib: Emacs
1940 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
1941 so that glib can't find it. Work around the bug by invoking
1942 waitpid only on subprocesses that Emacs itself creates.
1943 * process.c (create_process, record_child_status_change):
1944 Don't use special value -1 in pid field, as the caller now must
1945 know the pid rather than having the callee infer it.
1946 The inference was sometimes incorrect anyway, due to another race.
1947 (create_process): Set new 'alive' member if child is created.
1948 (process_status_retrieved): New function.
1949 (record_child_status_change): Use it.
1950 Accept negative 1st argument, which means to wait for the
1951 processes that Emacs already knows about. Move special-case code
1952 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
1953 processes that have already been waited for, by testing and
1954 clearing new 'alive' member.
1955 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
1956 now does this internally.
1957 (handle_child_signal): Let record_child_status_change do all
1958 the work, since we do not want to reap all exited child processes,
1959 only the child processes that Emacs itself created.
1960 * process.h (Lisp_Process): New boolean member 'alive'.
1962 Omit duplicate definitions no longer needed with gcc -g3.
1963 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
1964 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
1965 Define only as macros. There's no longer any need to also define
1966 these symbols as enums or as constants, since we now assume
1967 gcc -g3 when debugging.
1969 2012-11-03 Eli Zaretskii <eliz@gnu.org>
1971 * lisp.mk: Adjust comments to the fact that term/internal is now
1972 loaded from loadup.el.
1974 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
1975 (msdos_fatal_signal): New function.
1976 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
1979 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
1980 for GCC versions before 4.
1981 (emacs_raise): Define to call msdos_fatal_signal.
1983 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
1984 iterator when starting in the middle of a display or overlay
1987 2012-11-03 Chong Yidong <cyd@gnu.org>
1989 * process.c (wait_reading_process_output): Clean up the last
1992 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
1994 * process.c (wait_reading_process_output): Avoid a race condition
1995 with SIGIO delivery (Bug#11536).
1997 2012-11-03 Chong Yidong <cyd@gnu.org>
1999 * buffer.c (cursor_type): Untabify docstring.
2001 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2003 * frame.h (struct frame): Drop can_have_scroll_bars member
2004 which is meaningless for a long time. Adjust comments.
2005 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
2006 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2008 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
2010 * window.c (decode_next_window_args): Update window arg after
2011 calling decode_live_window and so fix crash reported at
2012 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
2013 by Juanma Barranquero <lekktu@gmail.com>.
2014 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
2015 * font.c (Ffont_at): Likewise.
2017 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
2019 * widget.c (resize_cb): New function.
2020 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
2021 (EmacsFrameResize): Check if all is up to date before changing frame
2024 2012-11-02 Eli Zaretskii <eliz@gnu.org>
2026 Implement backtrace output for fatal errors on MS-Windows.
2027 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
2028 (BACKTRACE_LIMIT_MAX): New macro.
2029 (w32_backtrace): New function.
2030 (emacs_abort): Use w32_backtrace when the user chooses not to
2031 attach a debugger. Update the text of the abort dialog.
2033 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2035 Window-related stuff cleanup here and there.
2036 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
2037 Use decode_any_window.
2038 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
2039 * xdisp.c (Fformat_mode_line): Likewise.
2040 * font.c (Ffont_at): Use decode_live_window.
2041 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
2042 * window.c (decode_next_window_args): Likewise.
2043 (decode_any_window): Remove static.
2044 * window.h (decode_any_window): Add prototype.
2045 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
2046 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
2049 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
2051 Remove pad from struct input_event.
2052 * termhooks.h (struct input_event): Remove padding field.
2054 * keyboard.c (event_to_kboard): Simplify because frame_or_window
2055 member is never cons for a long time. Adjust comment.
2056 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
2057 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
2058 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
2059 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
2061 2012-11-01 Eli Zaretskii <eliz@gnu.org>
2063 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
2065 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
2067 Fix crash when using Emacs as commit editor for git (Bug#12697).
2068 * callproc.c (setpgrp): Remove macro, as we now use setpgid
2069 and it is configured in conf_post.h.
2070 (Fcall_process): Don't invoke both setsid and setpgid; the former
2071 is enough, if it exists.
2072 * callproc.c (Fcall_process, child_setup):
2073 * process.c (create_process): Use setpgid.
2074 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
2076 * dispnew.c (init_display): Initialize the foreground group
2077 if we are running a tty display.
2078 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
2079 * lisp.h (init_foreground_group): New decl.
2080 * sysdep.c (inherited_pgroup): New static var.
2081 (init_foreground_group, tcsetpgrp_without_stopping)
2082 (narrow_foreground_group, widen_foreground_group): New functions.
2083 (init_sys_modes): Narrow foreground group.
2084 (reset_sys_modes): Widen foreground group.
2086 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
2088 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
2090 2012-10-31 Martin Rudalics <rudalics@gmx.at>
2092 * minibuf.c (read_minibuf): Restore current buffer since
2093 choose_minibuf_frame calling Fset_frame_selected_window may
2094 change it (Bug#12766).
2096 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
2098 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
2100 2012-10-30 Kenichi Handa <handa@gnu.org>
2102 * font.c (Ffont_at): If WINDOW is specified and it is not
2103 displaying the current buffer, signal an error.
2105 2012-10-29 Daniel Colascione <dancol@dancol.org>
2107 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
2108 In preparation for fixing bug#12739, move these functions from
2111 * coding.h, coding.c: ... to here, and compile them only when
2112 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
2113 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
2115 2012-10-28 Eli Zaretskii <eliz@gnu.org>
2117 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
2118 (timer_loop, getitimer, setitimer): Use it instead of
2119 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
2121 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
2124 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
2126 * nsterm.m (NO_APPDEFINED_DATA): New define.
2127 (last_appdefined_event_data): New variable
2128 (last_appdefined_event): Remove.
2129 (ns_select): Initialize t from last_appdefined_event_data instead
2130 of [last_appdefined_event data1].
2131 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
2132 remove last_appdefined_event (Bug#12698).
2134 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
2136 * frame.c (x_set_font): Catch internal error.
2138 2012-10-27 Eli Zaretskii <eliz@gnu.org>
2140 Avoid overflow in w32 implementation of interval timers.
2141 When possible, for ITIMER_PROF count only times the main thread
2143 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
2144 'volatile ULONGLONG' types. All the other data which was
2145 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
2146 (GetThreadTimes_Proc): New typedef.
2147 (w32_get_timer_time): New function, returns a suitable time value
2149 (timer_loop): Enter critical section when accessing ULONGLONG
2150 values of the itimer_data struct, as these accesses are no longer
2151 atomic. Call 'w32_get_timer_time' instead of 'clock'.
2152 Remove unused variable.
2153 (init_timers): Initialize s_pfn_Get_Thread_Times.
2154 (start_timer_thread): Don't assign itimer->caller_thread here.
2155 (getitimer): Assign itimer->caller_thread here.
2156 (setitimer): Always call getitimer to get the value of ticks_now.
2157 (sys_spawnve): Avoid compiler warning about format mismatch.
2159 2012-10-26 Eli Zaretskii <eliz@gnu.org>
2161 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
2162 mouse movement events if the menu bar is active. This avoids
2163 producing a busy "hour-glass" cursor by Windows if the mouse
2164 pointer is positioned over a tooltip shown for some menu item.
2166 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
2168 Don't assume process IDs fit in int.
2169 * emacs.c (shut_down_emacs) [!DOS_NT]:
2170 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
2171 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
2172 Use pid_t, not int, to store process IDs, as 'int'
2173 is not wide enough on a few platforms (e.g., AIX and IRIX).
2175 2012-10-23 Kenichi Handa <handa@gnu.org>
2177 The following change is to make face-font-rescale-alist work
2178 correctly for non-ASCII fonts.
2180 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
2181 (font_open_for_lface): Handle Vface_font_rescale_alist.
2183 2012-10-23 Chong Yidong <cyd@gnu.org>
2185 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
2187 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
2189 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
2191 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
2193 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
2196 2012-10-21 Glenn Morris <rgm@gnu.org>
2198 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
2200 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
2202 Port to OpenBSD 5.1.
2203 * frame.c (Fmouse_position, Fmouse_pixel_position):
2204 * xdisp.c (produce_stretch_glyph):
2205 Declare local vars only when they're needed.
2206 This is clearer and avoids a warning on OpenBSD about unused vars.
2207 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
2208 This is safer, and avoids OpenBSD warnings about unused vars.
2209 * keyboard.c (record_menu_key): Remove unnecessary decl.
2210 (poll_timer): Define only if POLL_FOR_INPUT is defined.
2211 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
2212 as our definition clashes with OpenBSD's.
2213 * xfaces.c (load_face_colors, check_lface_attrs)
2214 (get_lface_attributes_no_remap, get_lface_attributes)
2215 (lface_fully_specified_p, x_supports_face_attributes_p)
2216 (tty_supports_face_attributes_p, face_fontset, realize_face)
2217 (realize_x_face, realize_tty_face):
2218 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
2219 merely Lisp_Object *. This is more informative and avoids
2220 a warning on OpenBSD about accessing beyond an object's size.
2222 2012-10-20 Chong Yidong <cyd@gnu.org>
2224 * lread.c (Fload): Doc fix (Bug#12592).
2226 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
2228 * font.c (Ffont_at): Fix previous change.
2230 2012-10-19 Eli Zaretskii <eliz@gnu.org>
2232 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
2233 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
2236 * alloc.c (NSTATICS): Decrease to 0x800.
2238 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

2243 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
2245 * nsterm.m (ns_select): Check writefds before call to
2246 FD_ISSET (Bug#12668).
2248 2012-10-18 Daniel Colascione <dancol@dancol.org>
2250 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
2251 (staticpro): If we run out of staticpro slots, die with an
2252 informative error instead of just calling emacs_abort.
2254 2012-10-18 Martin Rudalics <rudalics@gmx.at>
2256 Fix two flaws reported by Dmitry Antipov.
2257 * window.c (Ftemp_output_buffer_show): Remove.
2258 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
2259 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.
2261 2012-10-17 Eli Zaretskii <eliz@gnu.org>

2264 ($(BLD)/vm-limit.$(O)):
2266 ($(BLD)/unexw32.$(O)):
2267 ($(BLD)/fileio.$(O)):
2268 ($(BLD)/dispnew.$(O)): Update dependencies.
2270 * w32term.h (w32_initialize_display_info, initialize_w32_display):
2273 * w32proc.c: Include ctype.h.
2275 * w32.h (init_environment, check_windows_init_file)
2276 (syms_of_ntproc, syms_of_ntterm, dostounix_filename)
2277 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
2278 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
2279 (sys_link): Add prototypes.
2281 * w32.c: Include w32select.h.
2282 (sys_access, e_malloc, sys_select): Add prototypes.
2283 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.
2285 * vm-limit.c [WINDOWSNT]: Include w32heap.h.
2287 * unexw32.c: Include lisp.h and w32.h.
2289 * term.c [WINDOWSNT]: Include w32term.h.
2291 * process.c [WINDOWSNT]: Add prototype of sys_select.
2293 * fileio.c [WINDOWSNT]: Include w32.h.
2295 * dispnew.c [WINDOWSNT]: Include w32.h.
2297 * cygw32.c (Fcygwin_convert_path_to_windows)
2298 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
2299 Lisp_Object values. (Bug#12661)
2301 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
2302 to Lisp_Object. (Bug#12661)
2304 2012-10-17 Kenichi Handa <handa@gnu.org>
2306 * xdisp.c (reseat_1): Make the information stored in it->cmp_it

2312 reset its buffer pointer to NULL (Bug#12652).
2314 2012-10-17 Dmitry Antipov <dmantipov@yandex.ru>
2316 Do not verify indirection counters of killed buffers (Bug#12579).
2317 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
2318 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.
2320 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
2322 * alloc.c (Fmake_byte_code): Fix typo in comment.
2323 * print.c (print_interval): Define as static to match prototype.
2324 * indent.c (disptab_matches_widthtab, recompute_width_table):
2327 2012-10-16 Dmitry Antipov <dmantipov@yandex.ru>
2329 * editfns.c (get_system_name): Remove.
2330 * lisp.h (get_system_name): Remove prototype.

2336 * dbusbind.c: Add comment explaining reason for previous change.
2338 2012-10-15 Martin Rudalics <rudalics@gmx.at>
2340 * window.c (Fwindow_end): Rewrite check whether cached position
2341 can be used (Bug#12600).
2342 (resize_frame_windows, grow_mini_window, shrink_mini_window):
2343 Set windows_or_buffers_changed.
2345 2012-10-15 Daniel Colascione <dancol@dancol.org>
2347 * dbusbind.c: Fix cygw32 build break when compiling with dbus
2348 enabled by undefining the symbol "interface", which the platform
2349 headers define to something incompatible.
2351 2012-10-14 Daniel Colascione <dancol@dancol.org>
2353 * image.c (init_tiff_functions, init_imagemagick_functions)
2354 (init_svg_functions): Fix cygw32 build break by using these
2355 functions only when WINDOWSNT _and_ HAVE_NTGUI.

2376 Fix some stat-related races.
2377 * fileio.c (Fwrite_region): Avoid race condition if a file is
2378 removed or renamed by some other process immediately after Emacs
2379 writes it but before Emacs stats it. Do not assume that stat (or
2381 * image.c (slurp_file): Resolve the file name with fopen + fstat
2382 rather than stat + fopen.
2383 (pbm_read_file) [0]: Remove unused code with stat race.
2384 * process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]:

2408 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
2410 * fileio.c (check_existing): New function.
2411 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
2412 instead of calling 'stat', when what's needed is to check whether
2413 a file exists. This avoids expensive system calls on MS-Windows.
2416 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
2418 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

2423 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
2425 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.

2465 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
2467 * marker.c (cached_modiff): EMACS_INT, not int.
2469 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
2470 instead of having a wrong decl.

2508 (detect_input_pending_run_timers):
2509 * process.c (wait_reading_process_output):
2510 Use unsigned for counter where wraparound-on-overflow is desired,
2511 since unsigned is guaranteed to have that behavior and signed is not.
2512 (read_char): Use ptrdiff_t for string length.
2513 (get_input_pending): Remove first argument, since it was always
2514 the same pointer-to-int (now pointer-to-boolean) &input_pending,
2515 and behave as if it had that value. Return new value of
2516 input_pending. All callers changed.
2517 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
2518 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
2520 * keymap.c (push_key_description): Omit last arg, which was always 1.
2521 All callers changed.
2523 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
2525 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

2541 Don't include termopts.h.
2543 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
2545 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
2547 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
2549 * commands.h (immediate_quit): Remove duplicate decl.
2551 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
2553 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
2555 (nsfont_open): Remove setting of Vfonts_in_cache.
2556 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
2558 2012-10-09 Eli Zaretskii <eliz@gnu.org>
2560 * w32fns.c (w32_last_error): Change the return value to DWORD, to
2561 match what GetLastError returns. Explain why the function is
2564 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
2565 'is_tooltip_frame', to avoid confusion with its global namesake.
2567 2012-10-08 Daniel Colascione <dancol@dancol.org>
2569 * xdisp.c (start_hourglass): Call w32_note_current_window when
2570 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
2571 build that caused Emacs to display the hourglass cursor forever.
2573 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
2574 which is broken under remote desktop, calculate the number of
2575 colors available for a display based on the display's number of
2576 planes and number of bits per pixel per plane. (bug#10397).
2578 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
2580 * nsfont.m (Vfonts_in_cache): New variable.
2581 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
2582 are used. Add cached fonts to Vfonts_in_cache.
2583 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
2585 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
2587 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
2589 (FONT_H): Define after FRAME_H.
2590 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
2591 Update dependencies.
2593 * w32term.c: Remove leftover declaration of keyboard_codepage.
2595 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2597 * makefile.w32-in (FONT_H): Add $(FRAME_H).
2598 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
2599 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
2600 (GLOBAL_SOURCES): Add cygw32.c.
2601 ($(BLD)/unexw32.$(O)):
2603 ($(BLD)/w32console.$(O)):
2604 ($(BLD)/w32fns.$(O)):
2605 ($(BLD)/w32heap.$(O)):
2606 ($(BLD)/w32menu.$(O)):
2607 ($(BLD)/w32proc.$(O)): Add w32common.h.
2609 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
2611 (x_to_w32_color): Don't modify the argument, modify a copy instead.
2613 2012-10-08 Daniel Colascione <dancol@dancol.org>
2615 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
2616 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
2617 accidental message numbering hole. Change other messages to
2620 * w32select.h (HAVE_W32SELECT): Remove.
2622 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
2623 w32common.h instead of w32heap.h.
2625 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
2626 (get_allocation_unit, get_processor_type, get_w32_major_version)
2627 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2628 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2629 (OS_NT, os_subtype, cache_system_info): Move declarations to
2632 * w32heap.c: Include w32common.h.
2633 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
2634 (w32_minor_version, w32_build_number, w32_subtype):
2635 Remove duplicate definitions.
2637 * w32fns.c: Include w32common.h; include w32heap.h only in
2640 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
2641 Use `report_file_error' instead of `error' in order to better
2642 inform users of what went wrong. Increase NTGUI_UNICODE file
2643 dialog box file name length to 32k, the maximum allowed by the NT
2646 * w32common.h: New file.
2647 (ROUND_UP, ROUND_DOWN, get_page_size)
2648 (get_allocation_unit, get_processor_type, get_w32_major_version)
2649 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
2650 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
2651 (OS_NT, os_subtype, cache_system_info): Move here.
2653 * unexw32.c, unexcw.c: Include w32common.h.
2655 * emacs.c (main): Use (defined (WINDOWSNT) || defined
2656 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
2657 to call syms_of_w32select.
2659 * cygw32.h: Remove obsolete EXFUN declarations.
2661 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
2663 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
2664 of w32inevt.o from SOME_MACHINE_OBJECTS.
2666 2012-10-08 Daniel Colascione <dancol@dancol.org>
2668 * image.c: Permanent fix for JPEG compilation issue --- limit
2669 jpeglib `boolean' redefinition to Cygwin builds.
2671 2012-10-08 Eli Zaretskii <eliz@gnu.org>
2673 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
2675 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
2678 2012-10-08 Daniel Colascione <dancol@dancol.org>
2680 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
2681 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
2682 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
2683 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
2684 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
2685 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
2686 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
2687 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
2688 now a supported configuration.
2690 * Makefile.in: consolidate image variables into LIBIMAGE; add
2691 W32_OBJ and W32_LIBS. Compile new files.
2694 (_DebPrint) declare tracing facility for W32 debugging. We need
2695 to unify tracing later.
2697 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
2698 unconditional use of W32 Unicode functions. Cygwin runs only on
2699 100% Unicode operating systems.
2701 * cygw32.c: New file. Define Cygwin-specific facilities.
2702 (Fcygwin_convert_path_to_windows)
2703 (Fcygwin_convert_path_from_windows): New user functions for
2704 accessing Cygwin path-munging routines.
2706 * cygw32.h: New file.
2707 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
2708 UTF-16LE strings temporarily inside non-Lisp-visible string
2711 (w32_strerror): Just what it says on the tin.
2713 * emacs.c: Make the NS fork-then-exec code for daemon-launching
2714 also run for Cygwin; both systems have the same problem with using
2715 GUI facilities in a forked child. Also call syms_of_cygw32,
2716 syms_of_w32select in correct places.
2718 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
2719 needs fork-then-exec for daemon launching.
2721 * font.h: Include frame.h.
2723 * image.c: Use the image library cache machinery only when we're
2724 compiling for native WINDOWSNT; Cygwin can use shared libraries
2725 like any other Unixlike system.
2727 * keyboard.c: Clarify a comment regarding the input loop.
2729 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
2730 functions directly instead of trying to detect at runtime that our
2731 host operating system supports them. We make this change for two
2732 reasons: Cygwin lacks support for the multibyte character
2733 conversion functions used by the legacy menu code, and Cygwin
2734 never needs to rely on non-Unicode APIs.
2736 * unexw32.c (hinst): Declare extern.
2738 * w32.c: Change header order;
2739 (w32_strerror): Move to w32fns.c because we need it for
2740 non-WINDOWSNT builds.
2742 * w32.h: Add #error macro to make sure we don't include w32.h for
2743 Cygwin builds. Remove w32select declarations.
2745 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
2746 w32fns.c. w32console.c is WINDOWSNT-only.
2748 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
2749 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
2751 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
2752 (w32_major_version, w32_minor_version, w32_build_number)
2753 (os_subtype, sound_type): Define here
2754 (w32_defined_color): Make color parameter const for consistency
2755 with other _defined_color functions.
2756 (w32_createwindow): Unconditionally call w32_init_class instead of
2757 doing so only when hprevinst is non-NULL. Plumbing hprevinst
2758 through the code is complex and unnecessary because class
2759 registration is practically free.
2760 (w32_name_of_message): New EMACSDEBUG-only function.
2761 (Fset_message_beep): Move here
2762 (Fx_open_connection): Require that the display name for Windows be
2763 "w32" for consistency, emacsclient disambiguation, and maybe, one
2764 day, multi-window-system support.
2765 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
2766 Cygwin files for W32 GUI facilities, since these clearly don't
2767 expect Cygwin names.
2768 (_DebPrint): Define.
2769 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
2770 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
2771 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
2772 (w32_last_error): Remove.
2774 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
2776 * w32heap.c (syspage_mask): Declare here.
2777 (cache_system_info): Remove.
2779 * w32inevt.c (faked_key): Define globally, not statically.
2780 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
2781 (w32_console_toggle_lock_key): Move to w32fns.c.
2783 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
2785 * w32proc.c (_DebPrint): Move to w32fns.c.
2786 * w32select.c: Include string.h, stdio.h for Cygwin.
2787 * w32select.h: New File.
2789 * w32term.c: Include io.h for non-CYGWIN builds; needed for
2791 (w32_message_fd): New variable. Under Cygwin, holds the file
2792 descriptor the system used to tell us about pending thread
2795 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
2796 that prevented compilation under non-WINDOWSNT systems.
2798 (w32_initialize): Open /dev/windows and assign it to
2799 w32_message_fd. Provide w32 feature.
2801 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
2802 (WM_EMACS_INPUT_READY): add.
2803 (prepend_msg, w32_message_fd): Declare globally.
2806 (keyboard_handle): Use only when WINDOWSNT.
2807 (notify_msg_ready): New function. Posts a message to the main
2808 thread's message queue under CYGWIN, which wakes up the main
2809 thread from select(2) by making the /dev/windows file descriptor
2810 ready. Under WINDOWSNT, it sets an event the same way the old
2813 (post, prepend_msg): Actually call notify_msg_ready instead of
2814 setting the input event directly.
2816 2012-10-07 Eli Zaretskii <eliz@gnu.org>
2818 * ralloc.c (relinquish): If a heap is ready to be relinquished,
2819 but it still has blocs in it, don't return it to the system,
2820 instead of aborting. (Bug#12402)
2822 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
2824 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
2826 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of

2855 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
2857 Improve sys_siglist detection.
2858 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
2859 defined as a macro, as is done in Solaris.
2860 (sys_siglist_entries): New macro.
2861 (save_strsignal): Use it.
2862 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
2863 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
2865 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
2867 * nsfns.m (Fx_create_frame): Call x_default_parameter with
2868 fullscreen/Fullscreen.
2870 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
2871 tobar_height is new.
2873 * nsterm.m (x_make_frame_visible): Check for fullscreen.
2874 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
2875 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.

2888 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
2890 2012-10-05 Eli Zaretskii <eliz@gnu.org>
2892 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
2894 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
2895 that time stamps of directories could also be changed.
2896 Don't request the too broad GENERIC_WRITE, only the more restrictive
2897 FILE_WRITE_ATTRIBUTES access rights.
2899 * fileio.c (Fset_file_times): Special-case ignoring errors for
2900 directories only on MSDOS, not on MS-Windows.
2902 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
2904 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
2906 2012-10-04 Eli Zaretskii <eliz@gnu.org>
2908 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
2909 see whether CreateFile failed.
2911 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
2913 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
2914 to avoid similar races.
2915 * keyboard.c (pending_signals): Now bool, not int.
2917 Port timers to OpenBSD, plus check for timer failures.
2918 OpenBSD problem reported by Han Boetes.
2919 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
2921 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
2922 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
2923 like OpenBSD, which has timer_settime but does not declare it.
2924 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
2925 whether to use itimerspec-related primitives. All uses of
2926 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
2928 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2930 * profiler.c (handle_profiler_signal): Fix a malloc race
2931 that caused Emacs to hang on Fedora 17 when profiling Lisp.
2933 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
2935 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
2937 2012-10-02 Eli Zaretskii <eliz@gnu.org>
2939 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
2940 consistent with the change in return value of 'safe_strsignal'.
2942 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
2944 Prefer plain 'static' to 'static inline' (Bug#12541).
2945 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
2946 (bidi_set_sor_type, bidi_push_embedding_level)
2947 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

2952 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
2953 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
2954 Now 'static', not 'static inline'.
2956 Count overruns when profiling; change units to ns.
2957 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
2958 Give extra weight to samples after overruns, to attempt to count
2959 the time more accurately.
2960 (setup_cpu_timer): Change sampling interval units from ms to ns, since
2961 the underlying primitives nominally do ns.
2962 (Fprofiler_cpu_start): Document the change. Mention that
2963 the sampling intervals are only approximate.
2965 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
2967 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
2969 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
2970 case for the special 0 coding-system.
2972 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
2973 (Fmake_overlay): Remove redundant tests.
2974 (fix_start_end_in_overlays): Remove redundant recentering.
2976 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
2978 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
2979 Update dependencies.
2981 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
2983 Fix a malloc race condition involving strsignal.
2984 A signal can arrive in the middle of a malloc, and Emacs's signal
2985 handler can invoke strsignal, which can invoke malloc, which is
2986 not portable. This race condition bug makes Emacs hang on GNU/Linux.
2987 Fix it by altering the signal handler so that it does not invoke
2989 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
2990 * process.c (status_message): Use const pointer, in case strsignal
2991 is #defined to safe_strsignal.
2992 * sysdep.c (sys_siglist, init_signals): Always define and
2993 initialize a substitute sys_siglist if the system does not define
2994 one, even if HAVE_STRSIGNAL.
2995 (safe_strsignal): Rename from strsignal. Always define,
2996 using sys_siglist. Return a const pointer.
2997 * syssignal.h (safe_strsignal): New decl.
2998 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
3000 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3002 * w32proc.c (timer_loop): Fix code that waits for timer
3003 expiration, to avoid high CPU usage.
3005 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
3007 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
3008 (sweep_weak_table): Remove redundant prototypes.
3010 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
3012 * emacs.c: Move the inclusion of TERM_HEADER after including
3013 windows.h on WINDOWSNT. This avoids compilation problems with
3016 2012-10-01 Eli Zaretskii <eliz@gnu.org>
3018 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
3019 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
3020 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
3021 as the previous version used 'void *'.
3023 * ralloc.c (ROUNDUP): Fix last change.
3024 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
3027 * w32proc.c <disable_itimers>: New static flag.
3028 (init_timers): Initialize it to zero, after creating the critical
3029 sections used by the timer threads.
3030 (term_timers): Set to 1 before deleting the critical sections.
3031 (getitimer, setitimer): If disable_itimers is non-zero, return an
3032 error indication without doing anything. Reported by Fabrice
3033 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
3034 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
3036 [!HAVE_SETITIMER]: Behave as the previous version that didn't
3039 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
3040 term_ntproc after all the other bookkeeping, to get timers working
3041 as long as possible.
3043 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
3045 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
3046 Suggested by Juri Linkov in
3047 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
3049 Prefer plain 'static' to 'static inline' (Bug#12541).
3050 With static functions, modern compilers inline pretty well by
3051 themselves; advice from programmers often hurts as much as it helps.
3052 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
3053 this change shrinks the text size of the Emacs executable by 1.1%
3054 without affecting CPU significantly in my benchmark.
3055 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

3135 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
3137 Revert the FOLLOW-SYMLINKS change for file-attributes.
3138 Doing it right would require several changes to Tramp, and there's
3139 not enough time to get that tested before the freeze today.
3140 * dired.c (directory_files_internal, Ffile_attributes):
3143 * frame.c (x_report_frame_params): Port better to wider ints.
3144 Do not assume that EMACS_UINT is the same width as uprintmax_t,
3145 or that pointers can be printed in 15 decimal digits.
3146 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

3182 * vm-limit.c (lim_data): Now size_t.
3183 (check_memory_limits): Adjust prototypes of real_morecore and
3184 __morecore to receive argument of type ptrdiff_t. Use size_t for

3273 to the buffer relocation which may be caused by ccl_driver.
3275 2012-09-30 Jan Djärv <jan.h.d@swipnet.se>
3277 * xfns.c (Fx_file_dialog): Update comment.
3279 * w32fns.c (Fx_file_dialog): Update comment.
3281 * nsfns.m (Fns_read_file_name): Add argument DIR_ONLY_P.

3307 (EmacsView): Add variables for fullscreen.
3308 (handleFS, setFSValue, toggleFullScreen): New in EmacsView.
3309 (EmacsFSWindow): New interface for fullscreen.
3311 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
3313 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
3315 2012-09-30 Chong Yidong <cyd@gnu.org>
3317 * fns.c (Frandom): Doc fix.
3319 2012-09-30 Martin Rudalics <rudalics@gmx.at>
3321 * window.c (Vwindow_combination_limit): New default value.
3322 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
3324 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
3326 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
3327 Suggested by Eli Zaretskii in
3328 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
3330 2012-09-30 Eli Zaretskii <eliz@gnu.org>
3332 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
3333 HAVE_TIMER_SETTIME is defined.
3335 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
3337 Profiler improvements: more-accurate timers, overflow checks.
3338 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
3339 signal.h, setjmp.h. Include systime.h instead.
3340 (saturated_add): New function.
3341 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
3342 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
3343 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
3345 (enum profiler_cpu_running): New enum.
3346 (profiler_cpu_running): Now of that enum type, not bool.
3347 All uses changed to store the new value.
3348 (handle_profiler_signal): Rename from sigprof_handler_1,
3349 for consistency with other handlers. Do not check whether
3350 cpu_log is a hash-table if garbage collecting, since it
3351 doesn't matter in that case.
3352 (deliver_profiler_signal): Rename from sigprof_handler,
3353 for consistency with other handlers.
3354 (setup_cpu_timer): New function, with much of what used to be in
3355 Fprofiler_cpu_start. Check for out-of-range argument.
3356 Prefer timer_settime if available, and prefer
3357 thread cputime clocks, then process cputime clocks, then
3358 monotonic clocks, to the old realtime clock. Use make_timeval
3359 to round more-correctly when falling back to setitimer.
3360 (Fprofiler_cpu_start): Use it.
3361 (Fprofiler_cpu_stop): Prefer timer_settime if available.
3362 Don't assume that passing NULL as the 2nd argument of setitimer
3363 is the same as passing a pointer to all-zero storage.
3364 Ignore SIGPROF afterwards.
3365 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
3366 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
3367 non-fatal signal handlers. Ignore SIGPROF on startup.
3368 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
3369 in profiler.c, since sysdep.c now uses it.
3371 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
3372 Suggested by Eli Zaretskii in
3373 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

3390 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
3391 (Frun_hook_with_args_until_failure): Doc fixes.
3393 2012-09-28 Eli Zaretskii <eliz@gnu.org>
3395 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
3396 Qautomatic_redisplay and change the symbol name. All users changed.
3398 2012-09-28 Tomohiro Matsuyama <tomo@cx4a.org>
3400 * profiler.c (sigprof_handler): Fix race condition.

3425 * character.h (MAYBE_UNIFY_CHAR): Remove.
3426 * charset.c, charset.h (maybe_unify_char): Now static.
3427 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
3428 Since this stuff is now private to charset.c, there's no need for
3429 a public macro and no need to inline by hand.
3431 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>

3462 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
3464 Prefer POSIX timers if available.
3465 They avoid a race if the timer is too close to the current time.
3466 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
3467 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
3468 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
3470 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3472 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
3473 CHAR_STRING_ADVANCE.

3493 * w32.h (Vlibrary_cache): Do not declare.
3495 2012-09-25 Eli Zaretskii <eliz@gnu.org>
3497 * w32proc.c (sys_signal): Handle all signals defined by the
3498 MS-Windows runtime, not just SIGCHLD. Actually install the signal
3499 handlers for signals supported by Windows. Don't override
3500 term_ntproc as the handler for SIGABRT.
3501 (sigaction): Rewrite to call sys_signal instead of duplicating its
3503 (sys_kill): Improve commentary.
3505 * w32.c (term_ntproc): Accept (and ignore) one argument, for
3506 consistency with a signature of a signal handler. All callers
3508 (init_ntproc): Accept an argument DUMPING. If dumping, don't
3509 install term_ntproc as a signal handler for SIGABRT, as that
3510 should be done by the dumped Emacs.
3512 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
3514 * w32select.c (term_w32select): Protect against repeated
3515 invocation by setting clipboard_owner to NULL after calling
3518 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
3519 and term_ntproc to their modified signatures.
3521 * character.c (char_string, string_char): Remove calls to
3522 MAYBE_UNIFY_CHAR. See the discussion starting at

3530 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
3532 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
3533 when encountering an unknown bytecode.
3535 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
3537 image.c, indent.c: Use bool for booleans.
3538 * dispextern.h (struct image_type): Members valid_p, load, init

3540 * image.c: Omit unnecessary static decls.
3541 (x_create_bitmap_mask, x_build_heuristic_mask):

3579 Move pid_t related decls out of lisp.h.
3580 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
3581 (interruptible_wait_for_termination):
3582 Move these decls from lisp.h to syswait.h, since they use pid_t.
3583 Needed on FreeBSD; see Herbert J. Skuhra in
3584 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
3585 * callproc.c: Include syswait.h.

3631 2012-09-23 Eli Zaretskii <eliz@gnu.org>
3633 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
3634 fatal_error_backtrace.
3636 * w32proc.c (sys_kill): Undo last change: don't do anything when
3637 invoked to deliver SIGABRT to our own process. This is now
3638 handled by emacs_raise.
3640 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
3642 * w32term.c (w32_read_socket): Remove leftover reference to
3643 interrupt_input_pending.
3645 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3647 Do not use SA_NODEFER.
3648 Problem reported by Dani Moncayo in
3649 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
3651 * sysdep.c (emacs_abort): Do not reset signal handler.
3652 * emacs.c (terminate_due_to_signal): Reset signal handler here.
3653 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
3654 wanted even on POSIXish hosts, and it doesn't work on Windows.
3656 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3658 * xterm.c (x_term_init): Call fixup_locale before and after calling
3659 gtk_init (Bug#12392).
3661 2012-09-23 Chong Yidong <cyd@gnu.org>
3663 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
3664 Vdynamic_library_alist.
3666 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
3667 (Fgnutls_available_p): Caller changed.
3669 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
3670 (Flibxml_parse_xml_region): Likewise.
3672 * dispextern.h (struct image_type): Remove arg from init function.
3674 * image.c (Finit_image_library, lookup_image_type)
3675 (define_image_type): Remove now-unneeded second arg.
3676 (init_xpm_functions, init_png_functions, init_jpeg_functions)
3677 (init_tiff_functions, init_gif_functions, init_svg_functions):
3678 Arglist and w32_delayed_load calling convention changed.
3679 (gs_type): Remove init_gs_functions; there is no such function.
3680 (valid_image_p, make_image): Fix caller to lookup_image_type.
3682 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
3684 Simplify and avoid signal-handling races (Bug#12471).
3686 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
3687 Avoid recursive loop if there's a fatal error in the function itself.
3688 * atimer.c (pending_atimers):
3689 * blockinput.h: Don't include "atimer.h"; no longer needed.
3690 (interrupt_input_pending): Remove. All uses removed.
3691 pending_signals now counts both atimers and ordinary interrupts.
3692 This is less racy than having three separate pending-signal flags.
3693 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
3695 Rename from their upper-case counterparts BLOCK_INPUT,
3696 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
3697 INPUT_BLOCKED_P, and turn into functions. All uses changed.
3698 This makes it easier to access volatile variables more accurately.
3699 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
3700 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
3701 that's more reliable if the code is buggy and sets
3702 interrupt_input_blocked to a negative value. All uses changed.
3703 * atimer.c (deliver_alarm_signal):
3704 Remove. No need to deliver this to the parent; any thread can
3705 handle this signal now. All uses replaced by underlying handler.
3706 * atimer.c (turn_on_atimers):
3707 * dispnew.c (handle_window_change_signal):
3708 * emacs.c (handle_danger_signal):
3709 * keyboard.c (kbd_buffer_get_event):
3710 Don't reestablish signal handler; not needed with sigaction.
3711 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
3713 Rework to avoid unnecessary accesses to volatile variables.
3714 (UNBLOCK_INPUT_TO): Now a function.
3715 (totally_unblock_input, unblock_input): New decls.
3716 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
3717 (init_data): Remove. Necessary stuff now done in init_signal.
3718 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
3719 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
3720 (fatal_error_code): Remove; no longer needed.
3721 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
3722 it doesn't always backtrace. All uses changed. No need to reset
3723 signal to default, since sigaction and/or die does that for us now.
3724 Use emacs_raise (FOO), not kill (getpid (), FOO).
3725 (main): Check more-accurately whether we're dumping.
3726 Move fatal-error setup to sysdep.c
3727 * floatfns.c: Do not include "syssignal.h"; no longer needed.
3728 * gtkutil.c (xg_get_file_name, xg_get_font):
3729 Remove no-longer-needed signal-mask manipulation.
3730 * keyboard.c, process.c (POLL_FOR_INPUT):
3731 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
3732 * keyboard.c (read_avail_input): Remove.
3733 All uses replaced by gobble_input.
3734 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
3735 (kbd_buffer_store_event_hold, gobble_input):
3736 (record_asynch_buffer_change) [USABLE_SIGIO]:
3737 (store_user_signal_events):
3738 No need to mess with signal mask.
3739 (gobble_input): If blocking input and there are terminals, simply
3740 set pending_signals to 1 and return. All hooks changed to not
3741 worry about whether input is blocked.
3742 (process_pending_signals): Clear pending_signals before processing
3743 them, in case a signal comes in while we're processing.
3744 By convention callers now test pending_signals before calling us.
3745 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
3746 New functions, to support changes to blockinput.h.
3747 (handle_input_available_signal): Now extern.
3748 (reinvoke_input_signal): Remove. All uses replaced by
3750 (quit_count): Now volatile, since a signal handler uses it.
3751 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
3752 All callers changed. Block SIGINT only if not already blocked.
3753 Clear sigmask reliably, even if Fsignal returns, which it can.
3754 Omit unnecessary accesses to volatile var.
3755 (quit_throw_to_read_char): No need to restore sigmask.
3756 * keyboard.c (gobble_input, handle_user_signal):
3757 * process.c (wait_reading_process_output):
3758 Call signal-handling code rather than killing ourselves.
3759 * lisp.h: Include <float.h>, for...
3760 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
3761 (pending_signals): Now volatile.
3762 (syms_of_data): Now const if IEEE floating point.
3763 (handle_input_available_signal) [USABLE_SIGIO]:
3764 (terminate_due_to_signal, record_child_status_change): New decls.
3765 * process.c (create_process): Avoid disaster if memory is exhausted
3766 while we're processing a vfork, by tightening the critical section
3768 (send_process_frame, process_sent_to, handle_pipe_signal)
3769 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
3771 (send_process): No need for setjmp/longjmp any more, since the
3772 SIGPIPE stuff is now gone. Instead, report an error if errno
3774 (record_child_status_change): Now extern. PID and W are now args.
3775 Return void, not bool. All callers changed.
3776 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
3777 Remove. All uses removed. This bug should be fixed now in a
3779 (wait_for_termination_1): Use waitpid rather than sigsuspend,
3780 and record the child status change directly. This avoids the
3781 need to futz with the signal mask.
3782 (process_fatal_action): Move here from emacs.c.
3783 (emacs_sigaction_flags): New function, containing
3784 much of what used to be in emacs_sigaction_init.
3785 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
3786 caught by emacs, to make races less likely.
3787 (deliver_process_signal): Rename from handle_on_main_thread.
3789 (BACKTRACE_LIMIT_MAX): Now at top level.
3790 (thread_backtrace_buffer, threadback_backtrace_pointers):
3792 (deliver_thread_signal, deliver_fatal_thread_signal):
3793 New functions, for more-accurate delivery of thread-specific signals.
3794 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
3795 (deliver_arith_signal): Handle in this thread, not
3796 in the main thread, since it's triggered by this thread.
3797 (maybe_fatal_sig): New function.
3798 (init_signals): New arg DUMPING so that we can be more accurate
3799 about whether we're dumping. Caller changed.
3800 Treat thread-specific signals differently from process-general signals.
3801 Block all signals while handling fatal error; that's safer.
3802 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
3804 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
3805 Ignore SIGPIPE unless batch.
3806 (emacs_backtrace): Output backtrace for the appropriate thread,
3807 which is not necessarily the main thread.
3808 * syssignal.h: Include <stdbool.h>.
3809 (emacs_raise): New macro.
3810 * xterm.c (x_connection_signal): Remove; no longer needed
3811 now that we use sigaction.
3812 (x_connection_closed): No need to mess with sigmask now.
3813 (x_initialize): No need to reset SIGPIPE handler here, since
3814 init_signals does this for us now.
3816 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
3818 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
3819 background rect may be larger (Bug#12245).
3821 2012-09-23 Chong Yidong <cyd@gnu.org>
3823 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
3825 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3827 * .gdbinit: Just stop at fatal_error_backtrace.
3828 See Stefan Monnier's request in
3829 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
3830 Remove no-longer-used query of system type.
3832 2012-09-22 Chong Yidong <cyd@gnu.org>
3834 * search.c (Freplace_match): Doc fix (Bug#12325).
3836 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
3838 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
3839 (Fline_end_position): Doc fix.
3841 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
3843 2012-09-22 Chong Yidong <cyd@gnu.org>
3845 * dispextern.h (struct image_type): Add new slot, storing a type
3846 initialization function.
3848 * image.c (define_image_type): Call the image initializer function
3849 if it is defined. Arguments and return value changed.
3850 (valid_image_p, make_image): Callers changed.
3851 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
3852 (gif_type, imagemagick_type, svg_type, gs_type):
3853 Add initialization functions.
3854 (Finit_image_library): Call lookup_image_type.
3855 (CHECK_LIB_AVAILABLE): Macro deleted.
3856 (lookup_image_type): Call define_image_type here, rather than via
3857 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
3858 (syms_of_image): Move define_image_type calls for xbm_type and
3859 pbm_type to lookup_image_type.
3861 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3863 * keyboard.c (timer_check_2): Move calculation of 'timers' and
3864 'idle_timers' from here ...
3865 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
3866 lists, to avoid infloops when the timer does something stupid,
3867 like reinvoke itself with the same or smaller time-out.
3870 2012-09-22 Martin Rudalics <rudalics@gmx.at>
3872 * window.c (Fsplit_window_internal): Handle only Qt value of
3873 Vwindow_combination_limit separately.
3874 (Qtemp_buffer_resize): New symbol.
3875 (Vwindow_combination_limit): New default value.
3878 2012-09-22 Eli Zaretskii <eliz@gnu.org>
3880 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
3881 the new overlay string. (Bug#10159)
3883 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
3885 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
3886 or that fprintf is async-signal-safe. POSIX doesn't require
3889 2012-09-22 Chong Yidong <cyd@gnu.org>
3891 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
3894 2012-09-22 Kenichi Handa <handa@gnu.org>
3896 * composite.c (composition_reseat_it): Handle the case that a
3897 grapheme cluster is not covered by a single font (Bug#12352).
3899 2012-09-21 Chong Yidong <cyd@gnu.org>
3901 * image.c (define_image_type): Avoid adding duplicate types to
3902 image_types (Bug#12463). Suggested by Jörg Walter.
3904 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3906 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
3907 (print_load_command_name): Add case LC_DATA_IN_CODE.
3908 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
3910 2012-09-21 Glenn Morris <rgm@gnu.org>
3912 * eval.c (Frun_hook_with_args_until_success)
3913 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
3915 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
3917 * fileio.c (Ffile_selinux_context): Only call freecon when
3918 lgetfilecon succeeded.
3919 (Fset_file_selinux_context): Likewise. (Bug#12444)
3921 2012-09-21 Eli Zaretskii <eliz@gnu.org>
3923 * xdisp.c (try_window_reusing_current_matrix): Under bidi
3924 reordering, locate the cursor by calling set_cursor_from_row; if
3925 that fails, clear the desired glyph matrix before returning a
3926 failure indication to the caller. Fixes leaving garbled display
3927 when fast scrolling with a down-key. (Bug#12403)
3928 (compute_stop_pos_backwards): Fix a typo that caused crashes while
3929 scrolling through multibyte text.
3931 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
3933 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
3934 calling mark_vectorlike since that's the one that marks the window.
3935 (mark_discard_killed_buffers): Mark the final cdr.
3936 * window.h (struct window): Move prev/next_buffers to the
3937 non-standard fields.
3938 * window.c (make_window): Initialize prev/next_buffers manually.
3940 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
3942 Omit unused arg EXPECTED from socket hooks.
3943 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
3944 * nsterm.m (ns_term_init):
3945 * termhooks.h (struct terminal.read_socket_hook):
3946 * w32inevt.c (w32_console_read_socket):
3947 * w32term.c (w32_read_socket):
3948 * xterm.c (XTread_socket):
3949 Omit unused arg EXPECTED. All callers changed.
3950 (store_user_signal_events): Return void, not int, since callers no
3951 longer care about the return value. All uses changed.
3953 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
3955 * w32gui.h (XParseGeometry): Do not declare.
3957 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
3959 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
3960 Ignore 'expected'. See Eli Zaretskii in
3961 <http://bugs.gnu.org/12471#8> (last line).
3963 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
3964 (XParseGeometry): Now static. Substitute extremal values for
3965 values that are out of range.
3967 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
3969 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
3971 * nsfns.m (XParseGeometry): Remove.
3972 (Fx_create_frame): Call x_set_offset to correctly interpret
3973 top_pos in geometry.
3975 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
3976 (Fx_parse_geometry): If there is a space in string, call
3977 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
3979 2012-09-17 Eli Zaretskii <eliz@gnu.org>
3981 * search.c (scan_buffer): Use character positions in calls to
3982 region_cache_forward and region_cache_backward, not byte
3983 positions. (Bug#12196)
3985 * w32term.c (w32_read_socket): Set pending_signals to 1, like
3986 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
3988 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
3989 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
3990 emacs_blocked_malloc, now deleted.
3992 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
3994 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
3995 The workaround was for improving performance on Solaris 2.4, but
3996 is getting in the way now. Emacs will still work if someone is
3997 still running Solaris 2.4 in a museum somewhere; Sun dropped
3998 support for Solaris 2.4 in 2003.
3999 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
4000 * process.c (create_process) [HAVE_WORKING_VFORK]:
4001 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
4002 since Emacs no longer uses vfork on that platform.
4004 2012-09-17 Glenn Morris <rgm@gnu.org>
4006 * emacs.c: Use COPYRIGHT.
4008 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
4010 Remove configure's --without-sync-input option (Bug#12450).
4011 When auditing signal-handling in preparation for cleaning it up,
4012 I found that SYNC_INPUT has race conditions and would be a real
4013 pain to fix. Since it's an undocumented and deprecated
4014 configure-time option, now seems like a good time to remove it.
4015 Also see <http://bugs.gnu.org/11080#16>.
4016 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
4017 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
4018 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4019 (malloc_hysteresis):
4020 (check_depth) [XMALLOC_OVERRUN_CHECK]:
4021 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
4022 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
4023 (dont_register_blocks, bytes_used_when_reconsidered)
4024 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
4025 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
4026 [!SYSTEM_MALLOC && !SYNC_INPUT]:
4027 Remove. All uses removed.
4028 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
4029 implementation, one that depends on whether the new macro
4030 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
4032 * atimer.c (run_timers, handle_alarm_signal):
4033 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
4034 (handle_async_input, process_pending_signals)
4035 (handle_input_available_signal, init_keyboard):
4036 * nsterm.m (ns_read_socket):
4037 * process.c (wait_reading_process_output):
4038 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
4039 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
4041 * xterm.c (XTread_socket):
4043 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
4044 * eval.c (handling_signal): Remove. All uses removed.
4045 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
4046 All uses replaced with the SYNC_INPUT version.
4047 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
4049 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4052 * font.c (Ffont_shape_gstring): Remove unused local.
4054 2012-09-16 Glenn Morris <rgm@gnu.org>
4056 * Makefile.in (clean): No longer run nextstep's clean.
4058 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
4060 (ns-app): Move here from ns.mk, and simplify.
4061 (clean): Simplify nextstep entry.
4062 * ns.mk: Remove file.
4064 2012-09-17 Kenichi Handa <handa@gnu.org>
4066 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
4067 not covert the last few charactes.
4069 2012-09-16 Kenichi Handa <handa@gnu.org>
4071 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
4072 here, but just check the validity of glyphs in the glyph-string.
4074 2012-09-16 Martin Rudalics <rudalics@gmx.at>
4076 * window.c (Fwindow_parameter, Fset_window_parameter):
4077 Accept any window as argument (Bug#12452).
4079 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
4081 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
4082 to ns_term_init to avoid memory leak.
4084 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
4085 explicit retain/release.
4086 (ns_term_init): Only allow one display. Initialize outerpool and
4089 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4091 Port _setjmp fix to POSIXish hosts as well as Microsoft.
4092 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
4093 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
4094 the Microsoft problem in a different way, by altering ../nt/config.nt.
4096 2012-09-15 Eli Zaretskii <eliz@gnu.org>
4111 * w16select.c: Remove inclusion of setjmp.h, as it is now included
4112 by lisp.h. This completes removal of setjmp.h inclusion
4113 erroneously announced in the previous commit. (Bug#12446)
4115 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
4118 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
4119 not defined as a macro. The latter happens on MS-Windows.
4122 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
4124 Port better to POSIX hosts lacking _setjmp (Bug#12446).
4125 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
4126 Some instances of '#include <setjmp.h>' removed, if the
4127 only reason for the instance was because "lisp.h" was included.
4128 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
4129 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
4130 and _longjmp with the new symbols. Emacs already uses _setjmp if
4131 available, so this change affects only POSIXish hosts that have
4132 sigsetjmp but not _setjmp, such as some versions of Solaris and
4133 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
4134 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
4135 (png_load_body) [HAVE_PNG]:
4136 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
4137 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
4138 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
4139 since PNG requires jmp_buf. This is the only exception to the
4140 general rule that we now use sys_setjmp and sys_longjmp.
4141 This exception is OK since this code does not change the signal
4142 mask or longjmp out of a signal handler.
4144 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
4146 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
4147 Include "syssignal.h", for 'main_thread'.
4149 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
4151 Avoid out-of-range marker position (Bug#12426).
4152 * insdel.c (replace_range, replace_range_2):
4153 Adjust markers before overlays, as suggested by comments.
4154 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
4155 Remove redundant check before calling offset_intervals.
4157 2012-09-14 Martin Rudalics <rudalics@gmx.at>
4159 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
4160 current buffer (Bug#12387).
4162 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
4164 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
4166 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4168 Use a more backwards-compatible timer format (Bug#12430).
4169 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
4170 vector element, not from the 4th, since PSECS is now at the end.
4171 (Fcurrent_idle_time): Doc fix.
4173 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
4175 Function to mark objects and remove killed buffers at once.
4176 * alloc.c (discard_killed_buffers): Rename to ...
4177 (mark_discard_killed buffers) ... new name. Add marking
4178 of remaining objects. Fix comment. Adjust users.
4179 (mark_object): Do not touch frame buffer lists here.
4180 * frame.c (delete_frame): Reset frame buffer lists here.
4182 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
4184 Better workaround for GNOME bug when --enable-gcc-warnings.
4185 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
4186 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
4187 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
4189 Simplify SIGIO usage (Bug#12408).
4190 The code that dealt with SIGIO was crufty and confusing, e.g., it
4191 played tricks like "#undef SIGIO" but these tricks were not used
4192 consistently. Simplify mostly by not #undeffing standard symbols,
4193 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
4194 or not as we please) rather than "defined SIGIO" (standard symbol
4195 that we probably shouldn't #undef).
4196 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
4197 Modules that need it can include it.
4198 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
4199 * dispextern.h (ignore_sigio): New decl.
4200 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
4201 unconditionally, since it's now a no-op if !USABLE_SIGIO.
4202 * emacs.c (shut_down_emacs):
4203 * keyboard.c (kbd_buffer_store_event_hold):
4204 Use ignore_sigio rather than invoking 'signal' directly.
4205 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
4207 (FIONREAD, SIGIO): Do not #undef.
4208 (tty_read_avail_input): Use #error rather than a syntax error.
4209 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
4210 for I_PIPE, used by SETUP_SLAVE_PTY.
4211 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
4212 * sysdep.c (croak): Remove; no longer needed. This bit of
4213 temporary code, with Fred N. Fish's comment that it's temporary,
4214 has been in Emacs since at least 1992!
4215 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
4216 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
4217 * syssignal.h (croak): Remove decl.
4218 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
4219 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
4220 now that we're termios-only.
4221 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
4222 * term.c (dissociate_if_controlling_tty): Use #error rather than
4225 Work around GCC and GNOME bugs when --enable-gcc-warnings.
4226 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
4227 to work around GNOME bug 683906.
4228 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
4229 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
4230 This works around GCC bug 54561.
4232 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4234 More fixes for 'volatile' and setjmp/longjmp.
4235 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
4236 * image.c (struct png_load_context) [HAVE_PNG]: New type.
4237 (png_load_body) [HAVE_PNG]:
4238 (jpeg_load_body) [HAVE_JPEG]:
4239 New function, with most of the old parent function's body.
4240 (png_load) [HAVE_PNG]:
4241 (jpeg_load) [HAVE_JPEG]:
4242 Invoke the new function, to avoid longjmp munging our locals.
4243 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
4244 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
4245 longjmp is passed 2, as the C standard doesn't guarantee this.
4246 Instead, store the failure code into mgr->failure_code.
4248 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4250 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
4251 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
4252 (syms_of_keyboard): Remove support for unread-command-char.
4254 2012-09-12 Eli Zaretskii <eliz@gnu.org>
4256 * w32proc.c (sys_kill): If PID is our process ID and the signal is
4257 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
4258 violation. (Bug#12426)
4260 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
4262 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
4264 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
4266 * eval.c: Add `inhibit-debugger'.
4267 (Qinhibit_debugger): New symbol.
4268 (call_debugger): Bind it instead of Qdebug_on_error.
4269 (maybe_call_debugger): Test Vinhibit_debugger.
4270 (syms_of_eval): Define inhibit-debugger.
4271 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
4272 (syms_of_xdisp): Remove inhibit-debug-on-message.
4274 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4276 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
4277 If a nonvolatile local variable is written before a _longjmp to
4278 the frame containing the variable, and is read after the _longjmp,
4279 the value read is indeterminate. Some local variables of type
4280 'struct handler' and 'struct catchtag' are used in this way, so
4281 mark each of their slots as volatile if the slot can be set before
4282 _longjmp and read afterwards.
4283 * lisp.h (struct handler): var and chosen_clause are now volatile.
4284 (struct catchtag): val, next, and pdlcount are now volatile.
4286 * bidi.c (bidi_push_it, bidi_pop_it):
4287 * fns.c (copy_hash_table):
4288 * image.c (define_image_type):
4289 * keyboard.c (kbd_buffer_store_event_hold):
4290 * process.c (Fprocess_send_eof):
4291 * xfaces.c (x_create_gc) [HAVE_NS]:
4292 * xgselect.c (xg_select):
4293 Prefer assignment to memcpy when either will do.
4295 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
4296 Use pointer-to-a-pointer to simplify and avoid a NILP check each
4297 time an item is removed. No need to mark this function 'inline';
4298 the compiler knows better than we do.
4300 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
4302 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
4303 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
4304 to change_frame_size (Bug#12388).
4305 (windowDidResize:): Pass YES to updateFrameSize.
4307 * nsterm.h: Add delay parameter to updateFrameSize.
4309 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4311 Discard killed buffers from deleted window and frame objects.
4312 This reduces an amount of references to killed buffers and
4313 helps GC to reclaim them faster.
4314 * alloc.c (discard_killed_buffers): New function.
4315 (mark_object): Use it for deleted windows and frames.
4316 (mark_object): If symbol's value is set up for a killed buffer
4317 or deleted frame, restore its global binding.
4318 * data.c (swap_in_global_binding): Add GC notice.
4319 (swap_in_symval_forwarding): Use convenient set_blv_where.
4320 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
4321 * window.h: ... to here.
4323 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
4325 Convenient macro to check whether the buffer is live.
4326 * buffer.h (BUFFER_LIVE_P): New macro.
4327 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
4328 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
4330 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
4332 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
4333 composition cases (Bug#12364).
4335 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
4336 overhang of succeeding glyphs overlapping box cursor.
4338 * w32term.c (x_draw_glyph_string): Likewise.
4340 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
4342 Simplify, document, and port floating-point (Bug#12381).
4343 The porting part of this patch fixes bugs on non-IEEE platforms
4344 with frexp, ldexp, logb.
4345 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
4347 * floatfns.c: Simplify discussion of functions that Emacs doesn't
4348 support, by removing commented-out code and briefly listing the
4349 C89 functions excluded. The commented-out stuff was confusing
4350 maintenance, e.g., we thought we needed cbrt but it was commented out.
4351 (logb): Remove decl; no longer needed.
4352 (isfinite): New macro, if not already supplied.
4353 (isnan): Don't replace any existing macro.
4354 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
4355 are present on all C89 platforms.
4356 (Ffrexp): Do not special-case zero, as frexp does the right thing
4358 (Flogb): Do not use logb, as it doesn't have the desired meaning
4359 on hosts that use non-base-2 floating point. Instead, stick with
4360 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
4361 frexp, to avoid getting an unspecified result.
4363 * xdisp.c (Qinhibit_debug_on_message): Now static.
4365 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
4367 * nsterm.m (ns_update_begin): Set clip path to whole view by using
4368 NSBezierPath (Bug#12131).
4370 2012-09-10 Chong Yidong <cyd@gnu.org>
4372 * fns.c (Fdelq, Fdelete): Doc fix.
4374 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
4376 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
4377 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
4379 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
4381 * lisp.h (make_lisp_ptr): New macro to replace XSET.
4382 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
4385 2012-09-09 Eli Zaretskii <eliz@gnu.org>
4387 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
4388 left fringe if the window has a left margin. This avoids leaving
4389 traces of the cursor because its leftmost pixel is not drawn over.
4391 * dispnew.c (update_window_line): When the left margin area of a
4392 screen line is updated, set the redraw_fringe_bitmaps_p flag of
4393 that screen line. (Bug#12277)
4395 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
4397 Assume C89 or later for math functions (Bug#12381).
4398 This simplifies the code, and makes it a bit smaller and faster,
4399 and (most important) makes it easier to clean up signal handling
4400 since we can stop worring about floating-point exceptions in
4401 library code. That was a problem before C89, but the problem
4402 went away many years ago on all practical Emacs targets.
4403 * data.c, image.c, lread.c, print.c:
4404 Don't include <math.h>; no longer needed.
4405 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
4406 might be autoconfigured, as that never happens.
4408 * doprnt.c (DBL_MAX_10_EXP):
4409 * print.c (DBL_DIG):
4410 Remove. C89 or later always defines these.
4411 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
4412 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
4413 (arith_error, domain_error, domain_error2):
4414 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
4415 no longer needed -- we simply return what C returns. All uses removed.
4416 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
4418 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
4419 Remove. All uses expanded, as these macros are no longer used
4420 more than once and are now more trouble than they're worth.
4421 (Ftan): Use tan, not sin / cos.
4422 (Flogb): Assume C89 frexp.
4423 (fmod_float): Assume C89 fmod.
4424 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
4425 (init_floatfns): Remove. All uses removed.
4427 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4429 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
4430 compositeToPoint for OSX < 10.6 (Bug#12390).
4432 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
4434 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
4435 This produces more-accurate results.
4437 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4439 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
4440 changes (Bug#12088).
4442 2012-09-08 Chong Yidong <cyd@gnu.org>
4444 * syntax.c (Fstring_to_syntax): Doc fix.
4446 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
4448 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
4449 in the internal border.
4450 (x_set_window_size): Remove static variables and their usage.
4451 (ns_redraw_scroll_bars): Fix NSTRACE arg.
4452 (ns_after_update_window_line, ns_draw_fringe_bitmap):
4453 Remove fringe/internal border adjustment (Bug#11052).
4454 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
4455 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
4456 (ns_fix_rect_ibw): Remove.
4457 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
4458 (ns_dumpglyphs_box_or_relief): Ditto.
4459 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
4461 (ns_dumpglyphs_image): Ditto.
4462 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
4464 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
4465 their usage. Add fringe_extended_p and its use as in other terms.
4466 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
4467 scroll bar was removed.
4468 (updateFrameSize): New function.
4469 (windowDidResize): Move code to updateFrameSize and call it.
4471 * nsterm.h (EmacsView): Add updateFrameSize.
4473 2012-09-07 Chong Yidong <cyd@gnu.org>
4475 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
4477 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
4479 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4481 More signal-handler cleanup (Bug#12327).
4482 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
4483 Problem introduced when merging patches. Noted by Eli Zaretskii in
4484 <http://bugs.gnu.org/12327#67>.
4485 * floatfns.c: Comment fix.
4486 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
4487 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
4488 and anyway the declaration is harmless even if SIGDANGER is not defined.
4489 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
4490 defined BROKEN_FIONREAD). systty.h formerly did this, but other
4491 source files not surprisingly expected syssignal.h to define, or
4492 not define, SIGIO, and it's cleaner to do it that way, for consistency.
4493 Include <sys/ioctl.h>, for FIONREAD.
4494 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
4495 This eliminates a problem whereby other files mysteriously had
4496 to include "syssignal.h" before including "systty.h" if they
4497 wanted to use "#ifdef SIGIO".
4499 2012-09-07 Eli Zaretskii <eliz@gnu.org>
4501 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
4503 * w32.c (sigemptyset): Empty the set.
4504 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
4506 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
4508 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
4510 * alloc.c (mark_buffer): Revert unsafe marking optimization.
4511 (mark_object): Likewise for frame objects.
4513 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
4515 * syssignal.h (handle_on_main_thread): Always declare,
4516 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
4517 This ports to platforms without HAVE_PTHREAD.
4519 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4521 Signal-handler cleanup (Bug#12327).
4522 Emacs's signal handlers were written in the old 4.2BSD style with
4523 sigblock and sigmask and so forth, and this led to some
4524 inefficiencies and confusion. Rewrite these to use
4525 pthread_sigmask etc. without copying signal sets around. Also,
4526 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
4527 'signal', and instead use functions that do not attempt to take
4528 over the system name space. This patch causes Emacs's text
4529 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
4530 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
4531 Do not include <signal.h> or "syssignal.h", as these
4532 modules do not use signals.
4533 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
4534 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
4535 Do not include <signal.h>, as "syssignal.h" does that for us now.
4536 * atimer.c (sigmask_atimers): New function.
4537 (block_atimers, unblock_atimers): New functions,
4538 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
4540 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
4541 no longer needed here.
4542 * emacs.c (main): Inspect existing signal handler with sigaction,
4543 so that there's no need to block and unblock SIGHUP.
4544 * sysdep.c (struct save_signal): New member 'action', replacing
4545 old member 'handler'.
4546 (save_signal_handlers, restore_signal_handlers):
4547 Use sigaction instead of 'signal' to save and restore.
4548 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
4549 New function. All users of 'signal' modified to use set_sighandler
4550 if they're writeonly, and to use sys_signal if they're read+write.
4551 (emacs_sigaction_init, forwarded_signal): New functions.
4552 (sys_signal): Remove. All uses replaced by calls to sigaction
4553 and emacs_sigaction_init, or by direct calls to 'signal'.
4554 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
4555 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
4556 all uses replaced by pthread_sigmask etc. calls.
4557 * syssignal.h: Include <signal.h>.
4558 (emacs_sigaction_init, forwarded_signal): New decls.
4559 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
4560 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
4561 (sigmask, sys_sigmask): Remove; no longer needed.
4562 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
4563 (sigblock, sigunblock, sigfree):
4564 (sigsetmask) [!defined sigsetmask]:
4565 Remove. All uses replaced by pthread_sigmask.
4566 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
4567 no longer need to be replaced, and its typical old uses
4568 are now done via emacs_sigaction_init and sigaction.
4569 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
4570 (sys_sigdel): Remove; unused.
4571 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
4573 2012-09-06 Eli Zaretskii <eliz@gnu.org>
4575 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
4576 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
4578 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4580 Explicitly mark buffer_defaults and buffer_local_symbols.
4581 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
4582 mark_local_symbols here.
4583 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
4584 since special buffers aren't marked here any more.
4585 (allocate_buffer): Chain new buffer with all_buffers here...
4586 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
4588 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
4589 (syms_of_buffer): Remove staticpro of the above.
4590 (init_buffer_once): Set names for buffer_defaults and
4591 buffer_local_symbols.
4593 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
4595 Use bool for booleans in font-related modules.
4596 * font.c (font_intern_prop, font_style_to_value)
4597 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
4598 (generate_otf_features, font_check_otf_features, font_check_otf)
4599 (font_match_p, font_list_entities, font_at):
4600 * fontset.c (fontset_id_valid_p, reorder_font_vector
4601 (fontset_find_font, Fset_fontset_font)
4602 (face_suitable_for_char_p) [0]:
4603 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
4604 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
4605 (m17n_flt_initialized, ftfont_shape_by_flt):
4606 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
4607 * nsfont.m (nsfont_draw):
4608 * w32font.c (w32font_draw):
4609 * w32term.c (x_draw_glyphless_glyph_string_foreground):
4610 Use bool for booleans.
4611 * font.h: Adjust to above API changes.
4612 (struct font, struct font_driver, struct font_driver_list):
4613 Use bool for booleans.
4614 (struct font): Remove useless member encoding_type.
4616 * fontset.c, xftfont.c: Omit unnecessary static decls.
4618 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
4620 * alloc.c (mark_object): Revert window marking code
4621 since it's unsafe for the Fset_window_configuration.
4623 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4625 Fix race conditions with signal handlers and errno (Bug#12327).
4626 Be more systematic about preserving errno whenever a signal
4627 handler returns, even if it's not in the main thread. Do this by
4628 renaming signal handlers to distinguish between signal delivery
4629 and signal handling. All uses changed.
4630 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
4631 * data.c (deliver_arith_signal): Rename from arith_error.
4632 * dispnew.c (deliver_window_change_signal): Rename from
4633 window_change_signal.
4634 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
4635 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
4636 * keyboard.c (deliver_input_available_signal): Rename from
4637 input_available_signal.
4638 (deliver_user_signal): Rename from handle_user_signal.
4639 (deliver_interrupt_signal): Rename from interrupt_signal.
4640 * process.c (deliver_pipe_signal): Rename from send_process_trap.
4641 (deliver_child_signal): Rename from sigchld_handler.
4642 * atimer.c (handle_alarm_signal):
4643 * data.c (handle_arith_signal):
4644 * dispnew.c (handle_window_change_signal):
4645 * emacs.c (handle_fatal_signal, handle_danger_signal):
4646 * keyboard.c (handle_input_available_signal):
4647 * keyboard.c (handle_user_signal, handle_interrupt_signal):
4648 * process.c (handle_pipe_signal, handle_child_signal):
4649 New functions, with the actual signal-handling code taken from the
4650 original respective signal handlers, sans the sporadic attempts to
4651 preserve errno, since that's now done by handle_on_main_thread.
4652 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
4653 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
4654 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4656 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4657 Move initialization of main_thread to sysdep.c's init_signals.
4658 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
4659 our usage, and simplifies the mainline code.
4660 (record_child_status_change): New static function, as a helper
4661 for handle_child_signal, and with most of the old child handler's
4663 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
4664 (handle_child_signal): Use the above.
4665 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
4666 Moved here from emacs.c.
4667 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
4668 code moved here from emacs.c's main function.
4669 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
4670 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
4671 This lets callers save and restore errno properly.
4673 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4675 Remove redundant or unused things here and there.
4676 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
4677 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
4678 * editfns.c (Fcompare_buffer_substrings): Likewise.
4679 * frame.h (struct terminal, struct font_driver_list):
4680 Remove redundant declarations.
4681 * window.h (Qleft, Qright): Likewise.
4683 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4685 Do not mark objects from deleted buffers, windows and frames.
4686 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
4687 (mark_object): Likewise for windows and frames.
4689 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
4691 * alloc.c (valid_lisp_object_p): Treat killed buffers,
4692 buffer_defaults and buffer_local_symbols as valid objects.
4693 Return special value to denote them.
4695 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
4697 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
4698 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
4699 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
4700 (file_name_absolute_p, Fsubstitute_in_file_name):

4706 * filelock.c (boot_time_initialized, get_boot_time)
4707 (get_boot_time_1, lock_file_1, within_one_second):
4708 * floatfns.c (in_float):
4709 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
4710 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
4711 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
4712 * lisp.h (struct Lisp_Hash_Table.cmpfn):
4713 * window.c (compare_window_configurations):
4714 Use bool for booleans.
4715 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
4716 (Fdefault_file_modes): Now mode_t, not int, for modes.
4717 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
4718 (internal_delete_file): Now returns void, not a (boolean) int,
4719 since nobody was looking at the return value.
4720 * lisp.h, window.h: Adjust to above API changes.
4722 * xdisp.c (set_message): Simplify and reindent last change.
4724 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
4726 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
4728 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
4730 * eval.c (call_debugger): Make the function non-static so that we
4731 can call it from set_message.
4733 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
4734 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
4736 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4738 Give more-useful info on a fatal error (Bug#12328).
4739 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
4740 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
4741 of doing the work ourselves.
4742 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
4743 do most of the work.
4744 (fatal_error_backtrace): New function, taken from the guts
4745 of the old fatal_error_signal, but with a new option to output
4747 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
4748 info about the signal than just its number.
4749 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
4750 * sysdep.c: Include <execinfo.h>
4751 (emacs_backtrace): New function, taken partly from the previous
4752 code of the 'die' function.
4753 (emacs_abort): Call fatal_error_backtrace rather than abort.
4755 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
4757 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
4758 eager (load-time) macro-expansion.
4759 * lisp.mk (lisp): Add macroexp.
4761 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4763 Simplify redefinition of 'abort' (Bug#12316).
4764 Do not try to redefine the 'abort' function. Instead, redo
4765 the code so that it calls 'emacs_abort' rather than 'abort'.
4766 This removes the need for the NO_ABORT configure-time macro
4767 and makes it easier to change the abort code to do a backtrace.
4768 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
4769 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
4770 Remove; sysdep.c's emacs_abort now takes its place.
4771 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
4772 'abort' changed to use 'emacs_abort'.
4773 * msdos.c (dos_abort) [defined abort]: Remove; not used.
4774 (abort) [!defined abort]: Rename to ...
4775 (emacs_abort): ... new name.
4776 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
4777 the place of the old 'abort' in emacs.c.
4778 * w32.c, w32fns.c (abort): Do not #undef.
4779 * w32.c (emacs_abort): Rename from w32_abort.
4781 2012-09-04 Eli Zaretskii <eliz@gnu.org>
4783 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
4784 offsets[j].dv, since the y axis of the screen coordinates points
4785 down, while the y axis of the font definition coordinates points
4786 up. This fixes display of Arabic diacritics such as KASRA and
4787 KASRATAN. (Bug#11860)
4789 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
4791 Be more systematic about _setjmp vs setjmp.
4792 * alloc.c (test_setjmp, mark_stack):
4793 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
4794 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
4795 (png_load, my_error_exit, jpeg_load):
4796 * process.c (send_process_trap, send_process):
4797 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
4798 The underscored versions are up to 30x faster on some hosts.
4799 Formerly, the code used setjmp+longjmp sometimes and
4800 _setjmp+_longjmp at other times, with no particular reason to
4801 prefer setjmp+longjmp.
4803 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
4805 Fix minor problem found by static checking.
4806 * buffer.c (Fdelete_all_overlays): Return nil.
4808 2012-09-03 Martin Rudalics <rudalics@gmx.at>
4810 * buffer.c (Fdelete_all_overlays): New function.
4812 2012-09-03 Chong Yidong <cyd@gnu.org>
4814 * gtkutil.c: Add extern decl for Qxft.
4816 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
4818 * emacs.c, eval.c: Use bool for boolean.
4819 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
4820 (malloc_using_checking) [DOUG_LEA_MALLOC]:
4821 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:

4825 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
4826 (maybe_call_debugger, Fbacktrace):
4827 * process.c (read_process_output, exec_sentinel):
4828 Use bool for booleans.
4829 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
4830 All callers changed.
4831 * eval.c (interactive_p): Omit always-true boolean argument
4832 EXCLUDE_SUBRS_P. All callers changed.
4833 * dispextern.h, lisp.h: Reflect above API changes.
4834 * firstfile.c (dummy): Use the address of 'main', whose signature
4835 won't change, instead of the address of 'initialize', whose
4836 signature just changed from int to bool.
4837 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
4838 * msdos.c (fatal_error_in_progress): ... from here.
4839 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
4841 (redisplay_internal, unwind_redisplay): Simply clear
4842 REDISPLAYING_P when unwinding, instead of saving its previous,
4843 always-false value and then restoring it.
4845 Clean up some extern decls.
4846 Mostly, this hoists extern decls out of .c files and into .h files.
4847 That way, we're more likely to catch errors if the interfaces change.
4848 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
4849 declare xg_mark_data.
4850 * dispextern.h (x_frame_parm_handlers):
4852 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
4853 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
4854 (Qultra_bold, Qoblique, Qitalic):
4855 Move extern decl here from .c file.
4856 * alloc.c (xg_mark_data) [USE_GTK]:
4858 * eval.c (Qlexical_binding):
4859 * fns.c (time) [!HAVE_UNISTD_H]:

4868 * xfont.c (x_clear_errors):
4869 * xterm.c (x_frame_parm_handlers):
4870 Remove now-redundant extern decls.
4871 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
4872 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
4874 * xfaces.c: Remove unnecessary static decls.
4875 * xterm.c (updating_frame): Remove decl of nonexistent object.
4877 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
4878 when building globals.h, as the objects that are not built on
4879 this host are not needed to compile C files on this host.
4881 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
4883 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
4885 * frame.h: Add missing prototype for x_wm_set_size_hint.
4887 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

4921 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
4923 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
4924 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

4929 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
4931 2012-09-01 Eli Zaretskii <eliz@gnu.org>
4933 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
4934 more than one grapheme cluster passed to the shaper: compute the
4935 offset adjustment values separately for each cluster. (Bug#11860)
4937 * image.c: Restore mistakenly removed inclusion of w32.h. Without
4938 it, GCC doesn't see prototypes of w32_delayed_load, and complains
4939 about implicit conversions from integer to pointer.
4941 2012-09-01 Daniel Colascione <dancol@dancol.org>
4943 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
4944 system used too early.
4946 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
4948 Better seed support for (random).
4949 * emacs.c (main): Call init_random.
4950 * fns.c (Frandom): Set the seed from a string argument, if given.
4951 Remove long-obsolete Gentzel cruft.

4958 Remove x_set_frame_alpha, x_bitmap_icon, x_make_frame_visible,
4959 x_make_frame_invisible, x_iconify_frame, x_free_frame_resources,

4961 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
4962 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
4963 all of which have been moved to common code.
4965 * xfaces.c: Include TERM_HEADER instead of listing all possible
4966 window-system headers.
4968 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)
4971 * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
4972 directly accessing frame internals.
4974 * w32font.h: Include font.h. Define syms_of_w32font and
4977 * process.c: Include TERM_HEADER instead of listing all possible
4978 window-system headers.
4980 * nsterm.h: Remove declarations now in frame.h.
4981 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
4983 * menu.c: Include TERM_HEADER instead of listing all possible
4984 window-system headers.
4986 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
4989 * keyboard.c: Include TERM_HEADER instead of listing all possible
4990 window-system headers.
4992 * image.c: Include TERM_HEADER instead of listing all possible
4993 window-system headers. Declare Vlibrary_cache when compiling for
4996 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
4997 window system declarations.
4999 * frame.h: Move common functions here: set_frame_menubar,
5000 x_set_window_size, x_sync, x_get_focus_frame,
5001 x_set_mouse_position, x_set_mouse_pixel_position,
5002 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

5022 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
5023 the current window system; include in list of objects to link into
5026 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5028 Remove mark_ttys function and fix tty_display_info initialization.
5029 * lisp.h (mark_ttys): Remove prototype.
5030 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
5031 to mark_ttys because all possible values of 'top_frame' slot are
5032 the frames which are reachable from Vframe_list.
5033 * term.c (mark_ttys): Remove.
5034 (init_tty): Safely initialize 'top_frame' slot with Qnil.
5036 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5038 Change struct frame bitfields from unsigned char to unsigned.
5039 * frame.h (struct frame): Change type of 'display_preempted',
5040 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
5041 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
5042 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
5043 bitfields from unsigned char to unsigned.
5045 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
5047 Remove unused member of struct x_output and struct w32_output.
5048 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
5049 * w32term.h (struct w32_output): Likewise.
5051 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
5053 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
5054 does not become zero (Bug#12234).
5056 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
5058 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
5059 for GCC 4.7.1 x86-64.
5061 2012-08-30 Glenn Morris <rgm@gnu.org>
5063 * lread.c (init_lread): For out-of-tree builds, only add the
5064 source directory's site-lisp dir to the load-path if it exists,
5065 consistent with in-tree builds. (Bug#12302)
5067 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
5069 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
5070 button_values to NULL. Call setStykeMask so dialogs get a close button.
5071 (windowShouldClose:): Set window_closed.
5072 (dealloc): New member, free button_values.
5073 (process_dialog:): Make member function. Remove window argument,
5074 replace window with self. Count buttons and allocate and store values

5083 Code formatting change.
5084 (timeout_handler:): Set timer_fired to YES.
5085 (runDialogAt:): Set timer_fired to NO.
5086 Handle click on close button as quit.
5088 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
5089 Add window_closed and button_values. Add void as return value for
5090 add(Button|String|Split). addButton takes int instead of Lisp_Object.
5091 Add process_dialog as new member.
5093 2012-08-28 Eli Zaretskii <eliz@gnu.org>
5095 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
5096 is not one of the heaps we manage. (Bug#12242)
5098 2012-08-28 Glenn Morris <rgm@gnu.org>
5100 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
5102 2012-08-28 Martin Rudalics <rudalics@gmx.at>
5104 * window.c (Fset_window_configuration): Remove handling of
5105 auto-buffer-name window parameter. Install revision of reverted

5111 * buffer.c (Fset_buffer_major_mode): Signal an error
5112 if the buffer is dead.
5113 (Fother_buffer, other_buffer_safely): Remove redundant
5116 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
5118 Always use set_buffer_if_live to restore original buffer at unwind.
5119 * buffer.h (record_unwind_current_buffer): New function.
5120 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:

5122 * undo.c, window.c: Adjust users.
5123 * buffer.c (set_buffer_if_live): Fix comment.
5125 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
5127 Fix usage of set_buffer_internal.
5128 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
5129 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
5130 * coding.c (decode_coding): Omit redundant test.
5131 * fileio.c (decide_coding_unwind): Likewise.
5132 * fns.c (secure_hash): Likewise.
5133 * insdel.c (modify_region): Likewise.
5134 * keyboard.c (command_loop_1): Likewise.
5135 * print.c (PRINTFINISH): Likewise.
5136 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
5138 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

5155 (do_pending_window_change, change_frame_size)
5156 (change_frame_size_1, sit_for):
5157 Use bool for boolean.
5158 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
5159 and remove last int (actually boolean) argument, which was always 0.
5160 All callers changed.
5161 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
5162 * dispextern.h (struct composition_it): Use bool for boolean.
5163 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
5164 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
5165 * dired.c (file_name_completion):
5166 Use bool for boolean. (This was missed in an earlier change.)
5168 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5170 * window.c (Fset_window_configuration): Revert first part of
5173 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
5175 * nsterm.h (NSPanel): New class variable dialog_return.
5177 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
5178 Initialize dialog_return.
5179 (windowShouldClose:): Use stop instead of stopModalWithCode.
5180 (clicked:): Ditto, and also set dialog_return (Bug#12258).
5181 (timeout_handler:): Use stop instead of abortModal. Send a dummy
5183 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
5186 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
5188 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.

5198 Use bool for booleans.
5199 * dired.c (file_name_completion):
5200 * process.h (fd_callback):
5201 Omit int (actually boolean) argument. It wasn't being used.
5203 * composite.h, lisp.h: Reflect above API changes.
5205 * cmds.c, coding.c: Use bool for booleans.
5206 * cmds.c (move_point, Fself_insert_command):

5227 * fileio.c (Finsert_file_contents):
5228 Use bool for booleans.
5229 * coding.h, lisp.h: Reflect above API changes.
5230 * coding.c: Remove unnecessary static function decls.
5231 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
5232 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
5233 not a boolean 'int', since callers never look at the return value.
5234 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
5235 * coding.h (decoding_buffer_size, encoding_buffer_size)
5236 (emacs_mule_string_char): Remove unused extern decls.
5237 (struct iso_2022_spec, struct coding_system):
5238 Use 'unsigned int : 1' for boolean fields, since there's more than one.
5239 (struct emacs_mule_spec): Remove unused field 'full_support'.
5240 All initializations removed.
5241 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
5243 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5245 Fix spare memory change (Bug#12286).
5246 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
5247 (valid_lisp_object_p): Likewise.
5249 2012-08-27 Martin Rudalics <rudalics@gmx.at>
5251 * window.c (Fset_window_configuration): Record any window's old
5252 buffer if it's replaced (see Bug#8789). If the new current
5253 buffer doesn't appear in the selected window, go to its old
5256 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
5258 Special MEM_TYPE_SPARE to denote reserved memory.
5259 * alloc.c (enum mem_type): New memory type.
5260 (refill_memory_reserve): Use new type for spare memory.
5261 This prevents live_cons_p and live_string_p from incorrect
5262 detection of uninitialized objects from spare memory as live.
5264 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
5267 * Makefile.in (.PHONY): versioclean -> versionclean.
5269 Remove unused external symbols.
5270 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
5271 * window.c (Qwindow_valid_p, decode_valid_window):
5272 Now static, not extern.
5273 * data.c (Qinterval): Remove; unused.
5274 (syms_of_data): Do not define 'interval'.
5275 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
5276 * window.h (decode_valid_window):
5279 * character.c, charset.c, chartab.c: Use bool for booleans.
5280 * character.c (lisp_string_width, string_count_byte8)
5281 (string_escape_byte8):
5282 * charset.c (charset_map_loaded, load_charset_map, read_hex):
5283 (load_charset_map_from_file, map_charset_chars)

5285 (Fdeclare_equiv_charset, find_charsets_in_text)

5288 (sub_char_table_set, sub_char_table_set_range)
5289 (char_table_set_range, optimize_sub_char_table)
5290 (map_sub_char_table):
5291 Use bool for boolean.
5292 * character.c (str_to_unibyte): Omit last boolean argument; it was
5293 always 0. All callers changed.
5294 * character.h, charset.h: Adjust to match previous changes.
5295 * character.h (char_printable_p): Remove decl of nonexistent function.
5296 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
5297 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
5298 are all boolean, so make them single-bit bitfields.
5300 * lisp.h (ASET): Remove attempt to detect side effects.
5301 It was meant to be temporary and it often doesn't work,
5302 because when IDX has side effects the behavior of IDX==IDX
5303 is undefined. See Stefan Monnier in
5304 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
5306 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
5308 * lisp.h (functionp): New function (extracted from Ffunctionp).
5309 (FUNCTIONP): Use it.
5310 * eval.c (Ffunctionp): Use it.
5312 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5314 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
5315 as that's faster and simpler than static storage. Don't bother
5316 with the g_main_context_query overhead if g_main_context_pending
5317 says no events are pending.
5318 (gfds, gfds_size): Remove these static vars.
5319 (xgselect_initialize): Remove; no longer needed.
5320 All uses and decls removed.
5322 * emacs.c (fatal_error_signal_hook): Remove.
5323 All uses removed. This leftover from old code was always 0.
5325 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
5326 * casefiddle.c (casify_object, casify_region):
5327 * casetab.c (set_case_table):
5328 * category.c, category.h (word_boundary_p):
5329 * category.h (CHAR_HAS_CATEGORY):
5330 Use bool for booleans, instead of int.
5332 2012-08-25 Eli Zaretskii <eliz@gnu.org>
5334 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
5336 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
5338 On assertion failure, print backtrace if available.
5339 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
5340 (die) [ENABLE_CHECKING]: Print a backtrace if available.
5341 * Makefile.in (LIB_EXECINFO): New macro.
5344 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
5345 * bytecode.c (exec_byte_code):
5346 * callint.c (check_mark, Fcall_interactively):
5347 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
5348 (getenv_internal, sync_process_alive, call_process_exited):
5349 * lisp.h (USE_SAFE_ALLOCA):
5350 Use bool for booleans, instead of int.
5351 * lisp.h, process.h: Adjust prototypes to match above changes.
5352 * callint.c (Fcall_interactively): Don't assume the mark's
5353 offset fits in 'int'.
5355 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
5357 * buffer.c, buffer.h: Use bool for boolean.
5358 * buffer.c (reset_buffer_local_variables)
5359 (buffer_lisp_local_variables, Fset_buffer_modified_p)
5360 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

5362 (overlay_touches_p, overlay_strings, Foverlay_put)
5363 (report_overlay_modification, call_overlay_mod_hooks):
5364 (mmap_enlarge, mmap_set_vars):
5365 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
5366 Use bool for booleans, instead of int.
5367 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
5368 since the 1-or-0 return value is always ignored anyway.
5369 (mmap_initialized_p):
5370 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
5371 * buffer.h, lisp.h: Adjust prototypes to match above changes.
5373 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5375 * bidi.c: Use bool for boolean.
5376 This is a bit more readable, and makes the text segment of bidi.o
5377 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
5378 Presumably it's faster too.
5379 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
5381 (bidi_cache_find_level_change, bidi_cache_iterator_state)
5382 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)

5384 (bidi_explicit_dir_char, bidi_level_of_next_char)
5385 (bidi_find_other_level_edge, bidi_move_to_visually_next):
5386 Use bool for booleans, instead of int.
5387 * dispextern.h (bidi_init_it, bidi_paragraph_init)
5388 (bidi_unshelve_cache): Adjust decls to match code.
5390 2012-08-23 Martin Rudalics <rudalics@gmx.at>
5392 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
5395 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
5397 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
5398 * atimer.h: Include <stdbool.h>.
5400 2012-08-22 Dan Nicolaescu <dann@gnu.org>
5402 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
5403 compile time tests instead of run time tests on systems that do
5405 (FRAME_MAC_P): Remove leftover from deleted code.
5406 * frame.c (syms_of_frame): Remove leftover from deleted code.
5408 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
5410 * nsterm.m (insertText:): Don't clear modifiers if code is space.
5412 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
5414 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
5415 Otherwise, the compiler complains about (A?B:C) where B is void
5416 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
5417 (fontset_add): Return void, for FONTSET_ADD.
5419 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5421 * alloc.c: Use bool for booleans.
5422 (gc_in_progress, abort_on_gc)
5423 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5424 (dont_register_blocks) [GC_MALLOC_CHECK]:
5425 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
5426 (check_string_bytes, make_specified_string, memory_full)
5427 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
5428 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
5429 (mark_stack, valid_pointer_p, make_pure_string)
5430 (Fgarbage_collect, survives_gc_p, gc_sweep):
5431 Use bool for booleans, instead of int.
5432 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
5433 Remove unused local.
5434 * alloc.c (PURE_POINTER_P):
5435 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
5436 * editfns.c (Fformat):
5437 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
5439 * fns.c (sweep_weak_table):
5440 * lisp.h (suppress_checking, push_message, survives_gc_p)
5441 (make_pure_string, gc_in_progress, abort_on_gc):
5442 * lread.c (readchar, read1):
5443 * print.c (Fprin1_to_string):
5444 * xdisp.c (push_message):
5445 Use bool for booleans affected directly or indirectly by
5448 Make recently-introduced setters macros.
5449 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
5450 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
5451 (set_fontset_default, set_fontset_fallback): Rename from their
5452 upper-case counterparts, and make them functions rather than macros.
5453 This is more consistent with the other recently-introduced setters.
5454 These don't need to be inline, since they're local.
5456 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
5458 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
5459 the loop (Bug#12247).
5461 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
5463 * lisp.h (vcopy): Use memcpy rather than our own loop.
5464 This fixes a performance regression introduced by the recent
5465 addition of vcopy. This means 'vcopy' will need to be modified
5466 for a copying collector, but that's OK. Also, tighten the
5467 checking in the assertion.
5469 2012-08-21 Eli Zaretskii <eliz@gnu.org>
5471 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
5472 components for RTL text (Bug#11860). Adjust X-OFFSET of each

5563 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>

5566 as gnulib does this if the system doesn't.
5567 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

6436 2012-08-04 Eli Zaretskii <eliz@gnu.org>
6438 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
6439 * w32.c (init_environment): Change the default values of many
6440 environment variables in dflt_envvars[] to NULL, to avoid pushing
6441 them into environment when they were not already defined.
6442 Remove the code that deletes site-lisp subdirectories from the default
6443 value of EMACSLOADPATH, as it is no longer needed.
6444 (check_windows_init_file): Now external, not static.
6445 Use Vload_path as is, without adding anything, as this function is now
6446 called when Vload_path is already set up.
6448 * w32.h (check_windows_init_file): Add prototype.
6450 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
6451 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
6452 compatibility with Posix platforms.
6453 (main): Move the call to check_windows_init_file to here from
6455 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
6456 any, in the DEFALT argument into the root of the Emacs build or
6457 installation tree, as appropriate.
6459 * callproc.c (init_callproc_1): Call decode_env_path instead of
6460 doing its equivalent by hand.
6461 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
6462 the code that sets Vexec_path run on MS-Windows.
6464 * lread.c (init_lread): Add comments to #ifdef's.
6466 * msdos.c (dos_set_window_size, IT_update_begin)

6474 Now constants, not macros.
6476 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
6478 Remove unnecessary casts involving pointers.
6479 These casts are no longer needed now that we assume C89 or later,
6480 since they involve casting to or from void *.

6482 (make_pure_float, make_pure_vector):
6483 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

6492 (x_get_window_property, x_get_window_property_as_lisp_data):
6493 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
6494 Remove unnecessary pointer casts.
6495 * alloc.c (record_xmalloc): New function.
6496 * lisp.h (record_xmalloc): New decl.
6497 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
6498 more like a function. This is because the pointer cast is not
6499 needed. All uses changed.
6500 * print.c (print_string, print_error_message): Avoid length recalc.
6502 Improve fix for macroexp crash with debugging (Bug#12118).
6503 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
6504 ARRAY_MARK_FLAG when checking subscripts, because ASET is
6505 not supposed to be invoked from the garbage collector.
6506 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
6507 (gc_aset): New function, which is like ASET but can be
6508 used in the garbage collector.
6509 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

6522 (map_w32_filename): Improve commentary. Simplify switch.
6523 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
6524 headers (most versions of MinGW w32api don't).
6525 (get_security_info, create_symbolic_link)
6526 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
6528 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
6529 in the argument file name.

6532 (sys_rename): Diagnose renaming of a symlink when the user doesn't
6533 have the required privileges.
6534 (get_file_security_desc_by_name): Rename from
6535 get_file_security_desc.
6536 (stat_worker): New function, with most of the guts of 'stat', and
6537 with addition of handling of symlinks and support for 'lstat'.
6538 If possible, get file's attributes and security information by
6539 handle, not by name. Produce S_IFLNK bit for symlinks, when
6540 called from 'lstat'.
6541 (stat, lstat): New functions, call 'stat_worker'.
6542 (symlink, readlink, careadlinkat): Rewritten to create and resolve
6543 symlinks when the underlying filesystem supports them.
6545 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
6547 Fix macroexp crash on Windows with debugging (Bug#12118).
6548 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
6549 checking subscripts; problem introduced with the recent
6550 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
6551 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
6552 since it's used in non-static inline functions now.
6554 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
6555 Don't assume buffer size fits in 'int'. Remove unused local.

6572 * category.c (CATEGORY_INLINE):
6573 * character.c (CHARACTER_INLINE):
6574 * charset.c (CHARSET_INLINE):
6575 * composite.c (COMPOSITE_INLINE):
6576 * dispnew.c (DISPEXTERN_INLINE):
6577 * sysdep.c (SYSTIME_INLINE):
6578 Define to EXTERN_INLINE, so that the corresponding functions
6579 are compiled into code.
6580 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
6581 (INLINE_HEADER_END): New macros.
6582 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

6604 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
6606 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
6607 This how ASET and AREF are supposed to work, and makes
6608 it easier to think about future improvements. See
6609 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
6610 * charset.h (set_charset_attr): New function.

6863 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
6864 does that unconditionally. Remove file, which is now empty.
6866 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
6869 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

6987 * w32inevt.c: Include w32inevt.h.
6988 (w32_read_console_input): New inline function, calls either
6989 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
6990 w32_console_unicode_input.
6991 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
6992 (w32_kbd_patch_key, key_event): Use the codepage returned by
6993 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
6994 (key_event): use uChar.UnicodeChar only if
6995 w32_console_unicode_input is non-zero.

7022 * alloc.c (listn): Fix the order the arguments are consed onto the
7025 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7026 enumeration constants, as PURE and HEAP are too general, and clash
7027 with other headers and sources, such as gmalloc.c and the
7028 MS-Windows system headers. All users changed.
7030 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7032 Revert last save_excursion_save and save_excursion_restore changes.
7033 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

7043 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
7045 Improve GDB symbol export (Bug#12036).
7046 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
7047 arms of an 'if', not using conditional expressions; otherwise GDB
7048 complains about the types in the unevaluated arm when the argument
7049 is an integer literal.
7050 (xgetint): Simplify expression.
7051 * alloc.c (gdb_make_enums_visible): New constant. This ports to
7052 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
7053 Zaretskii in <http://bugs.gnu.org/12036#13>.
7054 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
7055 needed now that we have gdb_make_enums_visible.
7056 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
7057 (enum enum_USE_LSB_TAG):
7058 New enum types, packaging up enums that need to be exported to GDB.

7076 * xdisp.c (syms_of_xdisp): Likewise.
7077 * xfns.c (syms_of_xfns): Likewise.
7079 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
7081 Fast save_excursion_save and save_excursion_restore.
7082 * lisp.h (struct Lisp_Excursion): New data type.
7083 (PVEC_EXCURSION): New pseudovector type.
7084 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
7085 to deal with it. Adjust comments.
7086 (init_marker, attach_marker): New prototype.
7087 (unchain_marker): Adjust prototype.

7096 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
7098 Fix export of symbols to GDB (Bug#12036).
7099 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
7100 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
7101 emacs.c, as this is a more-suitable home. Had this been done earlier
7102 the fix for 12036 would have avoided some of the problems noted in
7103 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
7104 would have been more obvious.
7105 * emacs.c: Do not include <verify.h>; no longer needed.
7106 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
7107 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
7108 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7109 Remove; now done in lisp.h.
7110 * lisp.h (PUBLISH_TO_GDB): New macro.

7113 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
7114 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
7115 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
7116 not be usable in #if. This simplifies things.
7118 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
7120 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
7122 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

7125 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
7126 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
7127 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
7128 Adjust to changes in lisp.h and emacs.c, by using
7129 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
7130 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
7131 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
7132 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
7133 instead of gdb_valbits.
7134 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
7135 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
7136 instead of gdb_array_mark_flag.
7137 (xboolvector): Get size from $->size, not $->header.size.
7138 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
7139 (xreload, hook-run, hookpost-run): Remove.
7140 * emacs.c: Include <verify.h>.
7141 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
7142 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
7144 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
7145 (gdb_USE_LSB_TAG): New enum constants.
7146 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
7147 Also define these as enum constants, so they're visible to GDB.
7148 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
7149 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
7150 as constants, so they're visible to GDB.
7151 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
7152 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
7153 Now enum constants, not macros, so they're visible to GDB.
7154 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
7155 more convenient now. All uses changed.
7156 (VALMASK) [USE_LSB_TAG]: Also define in this case.
7157 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
7159 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
7161 Explicitly free restriction data that are not needed anymore.
7162 * editfns.c (save_restriction_restore): Free restriction data.
7164 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
7166 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
7167 add argument, tune behavior, and adjust all callers.
7169 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
7171 Use typedef for EMACS_INT, EMACS_UINT.
7172 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
7173 than macros. This simplifies debugging in the usual case, since
7174 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
7175 and it allows expressions involving EMACS_INT casts.
7176 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
7178 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
7180 * nsterm.m (ns_read_socket): Return early if there is a modal
7183 2012-07-25 Martin Rudalics <rudalics@gmx.at>

7186 that FOCUS-FRAME can be omitted.
7188 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
7190 Adjust buffer text indirection counters at the end of Fkill_buffer.
7191 * buffer.c (Fkill_buffer): Adjust indirection counters when the
7192 buffer is definitely dead. This should really fix an issue reported
7193 by Christoph Scholtes again. (Bug#12007).
7194 (init_buffer_once): Initialize indirection counters of
7195 buffer_defaults and buffer_local_symbols (for sanity and safety).
7197 2012-07-24 Eli Zaretskii <eliz@gnu.org>
7199 * xdisp.c (init_iterator): Don't compute dimensions of truncation
7200 and continuation glyphs on tooltip frames, leave them at zero.
7201 Avoids continued lines in tooltips. (Bug#11832)
7203 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
7205 Simplify copy_overlay.
7206 * buffer.c (copy_overlay): Simplify. Use build_marker.

7212 or invalid. (Bug#12025)
7214 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
7215 it signals an error when a tooltip frame is being created.
7217 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7219 Cleanup miscellaneous objects allocation and initialization.
7220 * alloc.c (allocate_misc): Change to static. Add argument to
7221 specify the subtype. Adjust comment and users.
7222 (build_overlay): New function.
7223 * buffer.c (copy_overlays, Fmake_overlay): Use it.
7224 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
7225 (allocate_misc): Remove prototype.
7226 (build_overlay): Add prototype.
7228 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
7230 Swap buffer text indirection counters in Fbuffer_swap_text.

7996 The functional style also makes code easier to read and maintain.
7997 * systime.h: Include <sys/time.h> on all hosts, not just if

8038 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
8039 Prefer snprintf to strncpy.
8040 * nsterm.m (ns_term_init):
8041 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
8042 * nsterm.m (ns_term_init):
8043 Avoid the need for strncpy, by using build_string or
8044 make_unibyte_string directly. Use dtoastr, not snprintf.
8045 * process.c (Fmake_network_process): Diagnose service names that
8046 are too long, rather than silently truncating them or creating
8047 non-null-terminated names.

8064 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
8065 where argument type is known to be a Lisp_Cons.

8117 We include usg5-4-common.h, which defines them both.
8119 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
8120 O_RDONLY already includes it).
8122 Stop ns builds setting the EMACSLOADPATH environment variable.
8123 * nsterm.m (ns_load_path): Rename from ns_init_paths.
8124 Now it does not set EMACSLOADPATH, just returns the load-path string.
8125 * nsterm.h: Update accordingly.
8126 * lread.c [HAVE_NS]: Include nsterm.h.
8127 (init_lread) [HAVE_NS]: Use ns_load_path.

8132 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
8133 since the included bsd-common.h does so.
8135 Stop ns builds setting the EMACSPATH environment variable.
8136 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
8137 (ns_init_paths): Do not set EMACSPATH.
8138 * nsterm.h (ns_exec_path): Add it.
8139 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
8142 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
8144 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
8146 * process.c (wait_reading_process_output): 'waitchannels' was unset
8147 when read_kbd || !NILP (wait_for_cell); fix this.
8149 Add GCC-style 'const' attribute to functions that can use it.
8150 * character.h (char_resolve_modifier_mask):
8151 * keyboard.h (make_ctrl_char):
8152 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
8153 (init_character_once, next_almost_prime, init_fns, init_image)
8154 (flush_pending_output, init_sound):

8161 Add decls with ATTRIBUTE_CONST.
8163 Minor improvements to make_formatted_string.
8164 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
8165 where int is good enough, as vsprintf returns an int.
8166 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
8168 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8170 Use make_formatted_string to avoid double length calculation.
8171 * lisp.h (make_formatted_string): New prototype.
8172 * alloc.c (make_formatted_string): New function.

8177 * frame.c (make_terminal_frame, set_term_frame_name)
8178 (x_report_frame_params): Likewise.

8193 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
8195 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
8197 Move marker debugging code under MARKER_DEBUG.
8198 * marker.c (MARKER_DEBUG): Move marker debugging code under
8199 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
8200 for bootstrap with --enable-checking (~3x slowdown reported
8201 by Juanma Barranquero <lekktu@gmail.com>).
8202 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
8204 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
8206 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
8207 See <http://bugs.gnu.org/11825#29>.
8209 2012-07-08 Eli Zaretskii <eliz@gnu.org>
8211 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
8212 has no font, use the frame's font. (Bug#11813)
8213 (display_line): Add commentary about displaying truncation glyphs
8215 (produce_special_glyphs): Move here from term.c.
8217 * term.c (produce_special_glyphs): Move to xdisp.c.
8219 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
8222 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
8224 * xdisp.c (display_line): Avoid warning about implicit declaration
8227 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
8229 * lisp.h: Remove empty conditional.
8231 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8233 * lread.c (load_path_check): Now static.
8235 Fix some minor --with-ns problems found by static checking.
8236 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
8237 (x_set_font) [!HAVE_X_WINDOWS]:
8238 * image.c (xpm_load_image) [HAVE_NS]:
8239 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
8240 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
8241 Remove unused local.
8242 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
8243 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
8244 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
8245 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
8246 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
8247 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
8248 Fix pointer signedness problem.
8249 * xfaces.c (FRAME_X_FONT_TABLE):
8250 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
8252 2012-07-07 Glenn Morris <rgm@gnu.org>
8254 * lread.c (load_path_check): New function, split from init_lread.
8255 (init_lread): Reorganize. Motivation:
8256 If EMACSLOADPATH is set, check/warn about that rather than the
8257 defaults, which we are not going to use. Hence we can remove
8258 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
8259 Don't warn if site-lisp directories are missing.
8260 If not installed, start from a blank load-path, since
8261 PATH_LOADSEARCH refers to the eventual installation directories.
8263 2012-07-07 Eli Zaretskii <eliz@gnu.org>
8265 Support truncation and continuation glyphs on GUI frames, when
8266 fringes are disabled. (Bug#11832)
8267 * xdisp.c (init_iterator): Get dimensions of truncation and
8268 continuation glyphs even if on GUI frames.
8269 Adjust it->last_visible_x on GUI frames when the left or right fringes,
8270 or both, are absent.
8271 (start_display, move_it_in_display_line_to): Handle the case of a
8272 GUI frame without a fringe to display continuation or truncation
8274 (insert_left_trunc_glyphs): Support GUI frames: make sure
8275 truncation glyphs overwrite enough glyphs from the current line to
8276 have sufficient space in pixels.
8277 (display_line): Support truncation and continuation glyphs on GUI
8278 frames. If some spare pixels are left on the line after inserting
8279 the truncation glyphs, fill that space with a stretch glyph of a
8280 suitably computed width.
8282 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
8283 produce_glyphs, to support GUI sessions.
8285 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
8287 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
8289 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
8291 Do not require float-time's arg to fit in time_t (Bug#11825).
8292 This works better on hosts where time_t is unsigned, and where
8293 float-time is applied to the (negative) difference between two times.
8294 * editfns.c (decode_time_components): Last arg is now double *,
8295 not int *, and means to store all the result as a double, without
8296 worrying about whether the seconds part fits in time_t.
8297 All callers changed.
8298 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
8299 All callers changed.
8300 (Ffloat_time): Do not fail merely because the specified time falls
8301 outside of time_t range.
8303 2012-07-07 Glenn Morris <rgm@gnu.org>
8305 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

8320 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
8321 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
8322 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

8325 * xfont.c (compare_font_names): Redo to omit the need for casts.
8327 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
8329 * xfns.c (Fx_change_window_property): Doc fix.
8330 * w32fns.c (Fx_change_window_property): Doc fix.
8332 * w32fns.c (Fx_window_property): Accept the same arguments as the
8333 X Windows version. Doc fix.
8334 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
8336 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
8337 Eli Zaretskii <eliz@gnu.org>
8339 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
8340 Windows-specific code from nt/config.nt moved here.
8341 Obsolete settings removed.
8343 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8345 * process.c: Avoid unnecessary calls to gettime.
8346 (wait_reading_process_output): Don't get the time of day
8347 when gobbling data immediately and not waiting, as there's no need
8348 for it in that case. This removes a FIXME.
8350 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
8352 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
8353 is defined (Bug#11768).
8355 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8357 Fix marker debugging code.
8358 * marker.c (byte_char_debug_check): Do not perform the check
8359 if buffer is not multibyte.
8360 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8361 Call byte_char_debug_check with correct arguments.
8363 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8365 Compile marker debugging code only if ENABLE_CHECKING is defined.
8366 * marker.c (byte_char_debug_check, count_markers):
8367 Use only if ENABLE_CHECKING is defined.
8368 (byte_debug_flag): Remove.
8369 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
8370 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
8372 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8374 Avoid code repetition in marker-related functions.
8375 * marker.c (attach_marker): New function.
8376 (Fset_marker, set_marker_restricted, set_marker_both)
8377 (set_marker_restricted_both): Use it.
8378 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
8379 Consistently rename charno to charpos.
8380 (marker_position): Add eassert.
8381 (marker_byte_position): Convert to eassert.

8396 * editfns.c (buildmark): Remove.
8397 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
8398 (save_restriction_save): Use build_marker.
8399 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
8400 * window.c (save_window_save): Likewise.
8402 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
8404 Do not use Fdelete_overlay in delete_all_overlays
8405 to avoid redundant calls to unchain_overlay.
8406 * buffer.c (drop_overlay): New function.
8407 (delete_all_overlays, Fdelete_overlay): Use it.
8408 * minibuf.c (get_minibuffer): Fix comment.
8410 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
8412 Port to OpenBSD 5.1 amd64.
8413 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
8414 This is needed for OpenBSD, and should be harmless on all BSD systems.
8415 Also, include <sys/sysctl.h>, as it should be available on all
8416 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
8417 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
8418 use p_pid member, not kp_proc.pid.
8420 2012-07-06 Glenn Morris <rgm@gnu.org>
8422 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
8424 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
8426 More xmalloc and related cleanup.
8427 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
8428 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:

8434 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
8435 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
8437 Omit needless casts involving void * pointers and allocation.
8438 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
8439 as the former is more robust if P's type is changed.
8440 Prefer xzalloc to xmalloc + memset 0.
8441 Simplify malloc-or-realloc to realloc.
8442 Don't worry about xmalloc returning a null pointer.
8443 Prefer xstrdup to xmalloc + strcpy.
8444 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
8446 * keyboard.c (apply_modifiers_uncached): Prefer local array to
8447 alloca of a constant.
8449 2012-07-05 Eli Zaretskii <eliz@gnu.org>
8451 * xdisp.c (display_line): Fix horizontal pixel coordinates when
8452 hscroll is larger than the line width. Fixes long and futile
8453 looping inside extend_face_to_end_of_line (on a TTY) producing
8454 glyphs that are not needed and thrown away.
8456 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
8458 * marker.c (set_marker_restricted_both): Simplify by using

8472 followed by gtk_box_set_homogeneous (Bug#11768).
8473 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
8474 (update_theme_scrollbar_width, xg_create_scroll_bar):
8475 Use gtk_scrollbar_new (Bug#11768).
8476 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
8477 (is_box_type): New function (Bug#11768).
8478 (xg_tool_item_stale_p): Call is_box_type.
8479 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
8480 with default display (Bug#11768).

8484 * xdisp.c (window_hscroll_limited): New function.
8485 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
8486 coordinates when window's hscroll is set to insanely large
8489 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
8491 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

8558 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
8559 This should be fixed in a better way; see Eli Zaretskii in
8560 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
8561 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
8563 * fileio.c (time_error_value): Rename from special_mtime.
8564 The old name's problems were noted by Eli Zaretskii in
8565 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
8567 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
8568 This variable's comment says Emacs needs at least one GDB-visible
8569 symbol of type enum pvec_type, to work around GDB problems.
8570 The symbol's value doesn't matter.
8572 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
8573 that causes compilation to fail on pre-C99 compilers.
8575 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
8577 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

8588 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
8589 * lisp.h (enum pvec_type): Use fewer bits.
8590 (PSEUDOVECTOR_SIZE_BITS): New constant.
8591 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
8592 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
8593 change in pvec_type.
8594 (PSEUDOVECTOR_TYPEP): New macro.
8595 (TYPED_PSEUDOVECTORP): Use it.
8596 * fns.c (internal_equal): Adapt code to extract pvectype.

8598 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
8599 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
8600 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
8601 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
8602 (sweep_vectors): Use it. Use local var `total_bytes' instead of
8603 abusing vector->header.next.nbytes.
8604 (live_vector_p): Use PVEC_TYPE.
8605 (mark_object): Adapt code to extract pvectype. Use switch.
8607 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8609 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
8610 Tighten new eassert a bit.
8612 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8614 Fix compilation with --enable-gcc-warnings and -O1
8616 * doprnt.c (doprnt): Change type of tem to int, initialize
8617 to avoid compiler warning. Add eassert.
8618 * search.c (simple_search): Initialize match_byte to avoid
8619 compiler warning. Add eassert.
8621 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8623 Avoid weird behavior with large horizontal scrolls.
8624 Without this change, for example, large hscroll values would
8625 mess up Emacs's display on Fedora 15 x86, presumably due to
8626 overflows in int calculations in the display code.
8627 Also, if buffers had long lines, Emacs would freeze.
8628 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
8629 (set_window_hscroll): New function, containing the old guts of
8630 Fset_window_hscroll. Return the clipped value.
8631 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
8632 This avoids the need to check against PTRDIFF_MAX.
8634 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
8636 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
8638 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
8640 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
8642 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
8643 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
8644 since GCC 4.4.6 issues a bogus warning for them.
8646 Fix bugs in file timestamp newness comparisons.
8647 * fileio.c (Ffile_newer_than_file_p):
8648 * lread.c (Fload): Use full timestamp resolution of files,
8649 not just the 1-second resolution, so that files that are only
8650 slightly newer still count as newer.
8651 * fileio.c (Ffile_newer_than_file_p): Don't assume file
8652 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
8654 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
8656 * fileio.c: Improve handling of file time marker. (Bug#11852)
8657 (special_mtime): New function.
8658 (Finsert_file_contents, Fverify_visited_file_modtime):
8659 Use it to set special mtime values consistently.
8661 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
8663 * fileio.c (Finsert_file_contents): Properly handle st_mtime
8664 marker for non-existing file. (Bug#11852)
8666 2012-07-03 Glenn Morris <rgm@gnu.org>
8668 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
8669 and did not make it into globals.h).
8671 2012-07-03 Tom Tromey <tromey@redhat.com>
8673 * window.c (Fset_window_margins, Fset_window_fringes)
8674 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
8675 * textprop.c (Fprevious_property_change): No longer static.
8676 * syntax.c (Fsyntax_table_p): No longer static.
8677 * process.c (Fget_process, Fprocess_datagram_address): No longer

8692 * composite.c (Fcomposition_get_gstring): No longer static.
8693 * callproc.c (Fgetenv_internal): No longer static.
8695 * ccl.h: Remove EXFUNs.
8696 * buffer.h: Remove EXFUNs.
8697 * dispextern.h: Remove EXFUNs.
8698 * intervals.h: Remove EXFUNs.
8699 * fontset.h: Remove EXFUN.
8700 * font.h: Remove EXFUNs.
8701 * dosfns.c (system_process_attributes): Remove EXFUN.
8702 * keymap.h: Remove EXFUNs.
8703 * lisp.h: Remove EXFUNs.
8704 * w32term.h: Remove EXFUNs.
8705 * window.h: Remove EXFUNs.
8706 * xsettings.h: Remove EXFUN.
8707 * xterm.h: Remove EXFUN.
8709 2012-07-03 Glenn Morris <rgm@gnu.org>
8711 * lisp.h (Frandom): Make it visible to C.
8712 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
8713 buffer for invisible buffers. (Bug#1229)
8715 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8717 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
8718 values which aren't power of 2.
8719 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
8720 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
8723 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
8725 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
8727 * alloc.c (mark_object): Revert part of last patch to use `switch'.
8729 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8731 * alloc.c (allocate_vector_block): Remove redundant
8732 calls to mallopt if DOUG_LEA_MALLOC is defined.
8733 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
8734 avoid calls to mallopt if zero_vector is returned.
8736 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8738 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
8739 is enabled, avoid dereferencing NULL current_sblock if
8742 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
8744 Cleanup basic buffer management.
8745 * buffer.h (struct buffer): Change layout to use generic vector
8746 marking code. Fix some comments. Change type of 'clip_changed'
8747 to bitfield. Remove unused #ifndef old.
8748 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
8749 (GET_OVERLAYS_AT): Fix indentation.
8750 (for_each_per_buffer_object_at): New macro.
8751 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
8752 (Fbuffer_local_variables): Use it.
8753 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
8754 * alloc.c (allocate_buffer): Adjust to match new layout of
8755 struct buffer. Fix comment.
8756 (mark_overlay): New function.
8757 (mark_buffer): Use it. Use mark_vectorlike to mark normal
8758 Lisp area of struct buffer.
8759 (mark_object): Use it. Adjust marking of misc objects
8760 and related comments.
8762 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
8764 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
8765 wrapper that is not needed because the wrapped code is a no-op (zero
8766 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
8767 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
8769 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
8771 * alloc.c (mark_buffer): Simplify. Remove prototype.
8772 (mark_object): Add comment. Reorganize marking of vector-like
8773 objects. Use CHECK_LIVE for all vector-like objects except buffers
8774 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
8775 Avoid redundant calls to mark_vectorlike for bool vectors.
8777 2012-06-30 Glenn Morris <rgm@gnu.org>
8779 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
8781 * epaths.in (PATH_SITELOADSEARCH): New.
8782 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
8783 This is rather than relying on --enable-locallisppath elements
8784 having "site-lisp" in their names. (Bug#10208#25, 11658)
8786 2012-06-30 Eli Zaretskii <eliz@gnu.org>
8788 * w32proc.c (sys_select): Accept and ignore one more argument.
8790 * w32.c (emacs_gnutls_pull): Call select with one more argument.
8792 * sysselect.h [DOS_NT]: Don't include sys/select.h.
8793 (pselect) [!MS_DOS]: Redirect to sys_select.
8795 * sysdep.c: Don't include dos.h and dosfns.h.
8797 * process.c (sys_select):
8798 * msdos.c (sys_select): Accept one more argument and ignore it.
8800 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
8801 adapt data types and code to that.
8804 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
8805 which clashes with the gnulib function of the same name.
8807 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
8809 * font.c (font_style_to_value, font_style_symbolic)
8810 (font_prop_validate_style): Add type checks for values in
8813 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
8815 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
8818 2012-06-29 Eli Zaretskii <eliz@gnu.org>
8820 * xdisp.c (try_window_id): Undo last change.
8822 * w32.c (getwd): Adjust commentary about startup_dir.
8823 (init_environment): Always call sys_access, even in non-MSVC
8824 builds. Don't chdir to the directory of the Emacs executable.
8825 This undoes code from 1997 which was justified by the need to
8826 "avoid conflicts when removing and renaming directories". But its
8827 downside was that every relative file name was being interpreted
8828 relative to the directory of the Emacs executable, which can never
8829 be TRT. In particular, it broke sys_access when called with
8830 relative file names.
8831 (sys_access): Map GetLastError to errno.
8833 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8835 * window.h (struct window): Change type of 'fringes_outside_margins'

8839 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
8842 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
8844 * gnutls.c (emacs_gnutls_handshake):
8845 Add QUIT to make the loop interruptible.
8847 2012-06-29 Glenn Morris <rgm@gnu.org>
8849 * charset.c (init_charset): Make lack of etc/charsets fatal.
8851 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8853 * editfns.c (region_limit): Fix type mismatch.
8855 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
8857 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
8858 undefined. Convert from xassert to eassert.
8859 * nsmenu.m: Convert from xassert to eassert.
8860 * nsterm.m: Likewise.
8862 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
8864 * editfns.c (region_limit): Clip to narrowing (bug#11770).
8866 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
8868 Avoid integer overflow on scroll-left and scroll-right.
8869 * window.c (HSCROLL_MAX): New macro.
8870 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
8871 overflow when requested scroll falls outside ptrdiff_t range.
8873 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8875 * window.h (struct window): Change type of 'hscroll',
8876 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
8877 'last_modified' and 'last_overlay_modified' to EMACS_INT.
8878 Adjust users accordingly.
8879 * xdisp.c (try_cursor_movement): Replace type check with eassert.
8880 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
8881 from EMACS_INT to ptrdiff_t.
8882 (make_window): Omit redundant initialization.
8884 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

8888 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
8890 * window.h (struct window): Change type of 'use_time' and
8891 'sequence_number' from Lisp_Object to int.

8901 Fix GLYPH_DEBUG usage assuming that it may be undefined,
8902 adjust comments accordingly.

8953 avoid GCC warning about unused macro.

8957 * alloc.c (allocate_string): Omit intervals initialization.
8958 * alloc.c (make_uninit_multibyte_string): Initialize intervals
8959 as in make_pure_string and make_pure_c_string.
8961 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
8963 * alloc.c (allocate_string): Fix last change.
8965 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

9015 * alloc.c: Remove build_string.
9016 * lisp.h: Define build_string as static inline. This provides
9017 a better opportunity to optimize away calls to strlen when the
9018 function is called with compile-time constant argument.
9019 * image.c (imagemagick_error): Convert to build_string.
9020 * w32proc.c (sys_spawnve): Likewise.
9021 * xterm.c (x_term_init): Likewise.
9023 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
9025 Use sprintf return value instead of invoking strlen on result.
9026 In the old days this wasn't portable, since some sprintf
9027 implementations returned char *. But they died out years ago and
9028 Emacs already assumes sprintf returns int.
9029 Similarly for float_to_string.
9030 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
9031 * ccl.c (ccl_driver):
9032 * character.c (string_escape_byte8):

9035 * print.c (print_object):
9036 * xdisp.c (message_dolog):
9037 * xfns.c (syms_of_xfns):
9038 Use sprintf or float_to_string result to avoid need to call strlen.
9039 * data.c (Fnumber_to_string):
9040 Use make_unibyte_string, since the string must be ASCII.
9041 * lisp.h, print.c (float_to_string): Now returns int length.
9042 * term.c (produce_glyphless_glyph):
9043 Use sprintf result rather than recomputing it.
9045 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
9046 * Makefile.in (ALL_CFLAGS):
9047 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

9053 strcasecmp if available.

9078 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

9081 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
9083 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
9084 instead of truncating it to 63 (admittedly a generous limit).
9086 * process.c: Fix spelling and caps in comments.
9088 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
9090 * emacs.c (setpgrp): Remove definition, unused.

9180 language ID in the event parameters.
9182 * w32term.c (w32_read_socket): Put the new keyboard codepage into

9214 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
9216 Support higher-resolution time stamps (Bug#9000).
9217 The time stamps are only nanosecond-resolution at the C level,
9218 since that's the best that any real-world system supports now.
9219 But they are picosecond-resolution at the Lisp level, as that's
9220 easy, and leaves room for future OS improvements.
9222 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
9225 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
9226 Don't get current time unless it's needed.
9228 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
9229 now provides it if it's absent.
9230 (start_atimer): Port to higher-res time stamps.
9231 Check for time stamp overflow. Don't get current time more
9232 often than is needed.
9234 * buffer.h (struct buffer): Buffer modtime now has high resolution.
9235 Include systime.h, not time.h.
9236 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
9238 * dired.c: Include stat-time.h.
9239 (Ffile-attributes): File times now have higher resolution.
9241 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
9242 (struct image): Timestamp now has higher resolution.
9244 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
9245 has at least microseconds now. All uses removed.
9246 (update_frame, update_single_window, update_window, update_frame_1)
9247 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
9248 (duration_to_sec_usec): Remove; no longer needed.
9250 * editfns.c (time_overflow): Now extern.

9252 (float-time, Fformat_time_string, Fcurrent_time_string)
9253 (Fcurrent_time_zone): Accept and generate higher-resolution
9255 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
9256 (decode_time_components, lisp_seconds_argument): New functions.
9257 (make_time): Now static.
9258 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
9259 Report an error if the time is invalid, rather than having the caller
9262 * fileio.c: Include <stat-time.h>
9263 (Fcopy_file): Copy higher-resolution time stamps.
9264 Prefer to set the time stamp via a file descriptor if that works.
9265 (Fset_file_times, Finsert_file_contents, Fwrite_region)
9266 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
9267 (Fvisited_file_modtime, Fset_visited_file_modtime):
9268 Support higher-resolution time stamps.
9270 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
9272 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
9274 * image.c (prepare_image_for_display, clear_image_cache)
9275 (lookup_image): Port to higer-resolution time stamps.
9277 * keyboard.c (start_polling, bind_polling_period):
9278 Check for time stamp overflow.
9279 (read_char, kbd_buffer_get_event, timer_start_idle)
9280 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
9281 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
9282 Port to higher-resolution time stamps. Do not assume time_t is signed.
9283 (decode_timer): New function. Timers are now vectors of length 9,
9284 not 8, to accommodate the picosecond component.
9285 (timer_check_2): Use it.
9287 * nsterm.m (select_timeout, timeval_subtract): Remove.
9288 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
9289 as they're a bit more accurate and handle overflow better.
9290 (ns_select): Change prototype to be compatible with pselect.
9291 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
9292 * nsterm.h (ns_select): Adjust prototype.
9294 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
9295 us-resolution time stamps.
9296 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
9298 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
9300 * lisp.h (time_overflow): New decl.
9301 (wait_reading_process_output): First arg is now intmax_t, not int,
9302 to accommodate larger waits.
9304 * process.h (struct Lisp_Process.read_output_delay):
9305 Now counts nanoseconds, not microseconds.
9306 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
9308 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
9309 (wait_reading_process_output):
9310 Port to ns-resolution time stamps.
9311 (Faccept_process_output, wait_reading_process_output):
9312 Check for time stamp overflow. Do not assume time_t is signed.
9313 (select_wrapper): Remove; we now use pselect.
9314 (Fprocess_attributes): Now generates ns-resolution time stamps.
9316 * sysdep.c: Include utimens.h. Don't include utime.h
9317 or worry about struct utimbuf; gnulib does that for us now.
9318 (gettimeofday): Remove; gnulib provides a substitute.
9319 (make_timeval): New function.
9320 (set_file_times): Now sets ns-resolution time stamps.
9321 New arg FD; all uses changed.
9322 (time_from_jiffies, ltime_from_jiffies, get_up_time)
9323 (system_process_attributes):
9324 Now returns ns-resolution time stamp. All uses changed.
9325 Check for time stamp overflow.
9327 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
9328 provides a substitute now.
9330 * systime.h: Include timespec.h rather than sys/time.h and time.h,
9331 since it guarantees struct timespec.
9332 (EMACS_TIME): Now struct timespec, so that we can support
9333 ns-resolution time stamps.
9334 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
9335 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
9336 (EMACS_USECS): Remove.
9337 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
9338 so multiply the arg by 1000 before storing it.
9339 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
9341 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
9342 Port to ns-resolution time stamps.
9343 (EMACS_TIME_NEG_P): Remove; replaced by....
9344 (EMACS_TIME_SIGN): New macro.
9345 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
9346 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
9347 (set_file_times, make_time, lisp_time_argument): Adjust signature.
9348 (make_timeval, make_lisp_time, decode_time_components): New decls.
9349 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
9350 that it mishandled time_t overflow. You can't compare by subtracting!
9351 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
9352 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
9354 * term.c: Include <sys/time.h>.
9355 (timeval_to_Time): New function, for proper overflow wraparound.
9356 (term_mouse_position, term_mouse_click): Use it.
9358 * undo.c (record_first_change): Support higher-resolution time stamps
9360 (Fprimitive_undo): Use them when restoring time stamps.
9362 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
9363 (w32_get_internal_run_time):
9364 Port to higher-resolution Emacs time stamps.
9365 (ltime): Now accepts single 64-bit integer, as that's more convenient
9368 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
9370 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
9371 for compatibility with pselect. Support ns-resolution time stamps.
9373 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
9375 * xselect.c (wait_for_property_change, x_get_foreign_selection):
9376 Check for time stamp overflow, and support ns-resolution time stamps.
9378 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
9379 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
9380 (timeval_subtract): Remove; no longer needed.
9381 (XTflash, XTring_bell, x_wait_for_event):
9382 Port to ns-resolution time stamps. Don't assume time_t is signed.
9384 2012-06-22 Chong Yidong <cyd@gnu.org>
9386 * xdisp.c (x_consider_frame_title): Revert last change.
9388 2012-06-22 Eli Zaretskii <eliz@gnu.org>
9390 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
9391 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
9392 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
9393 staticidx goes up to 1597 out of 1600 = 0x640.)
9395 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
9397 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
9398 Otherwise, the umask might be mistakenly 0 while handling input signals.
9400 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
9402 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

9407 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
9408 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
9409 access to `contents' member of Lisp_Vector objects with AREF and ASET
9412 2012-06-19 Chong Yidong <cyd@gnu.org>
9414 * frame.c (delete_frame): When selecting a frame on a different
9415 text terminal, do not alter the terminal's top-frame.

9419 (unwind_format_mode_line): Restore them.
9420 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
9422 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
9423 since tty frames can be explicitly named.
9424 (prepare_menu_bars): Likewise.
9426 * term.c (Ftty_top_frame): New function.
9428 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

9431 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
9432 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
9433 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
9434 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
9435 (METER_1, METER_2): Simplify.
9437 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
9439 * data.c (Fdefalias): Return `symbol' (bug#11686).
9441 2012-06-18 Martin Rudalics <rudalics@gmx.at>
9443 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
9444 gets killed during executing of this function (Bug#11665).
9445 Try to always return Qt when the buffer has been actually killed.
9446 (Vkill_buffer_query_functions): In doc-string say that functions
9447 run by this hook should not change the current buffer.
9449 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
9451 Fix recently-introduced process.c problems found by static checking.
9452 * process.c (write_queue_push, write_queue_pop, send_process):
9453 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
9454 (write_queue_pop): Fix pointer signedness problem.
9455 (send_process): Remove unused local.
9457 2012-06-17 Chong Yidong <cyd@gnu.org>

9460 frames that are not on top.
9462 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
9464 * process.c (make_process): Initialize write_queue.
9465 (write_queue_push, write_queue_pop): New functions.

9469 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
9471 * lisp.h (eassert): Assume C89 or later.
9472 This removes the need for CHECK.
9473 (CHECK): Remove. Its comments about always evaluating its
9474 argument were confusing, as 'eassert' typically does not evaluate
9477 * coding.c (produce_chars): Use ptrdiff_t, not int.
9479 * xterm.c (x_draw_underwave): Check for integer overflow.
9480 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
9482 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
9484 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

9664 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
9665 code works fine either way, and efficiency is not a concern here,
9666 as the union type is for debugging, not for production.
9667 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
9668 Use an inline function on all platforms when using the union type,
9669 since this is simpler and 'static inline' can be used portably
9671 (LISP_INITIALLY_ZERO): New macro.
9672 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
9673 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

9811 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
9813 * doprnt.c (doprnt): Truncate multibyte char correctly.
9814 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
9815 would mishandle a string argument "Xc" if X was a multibyte
9816 character of length 2: it would truncate after X's first byte
9817 rather than including all of X.
9819 2012-06-06 Chong Yidong <cyd@gnu.org>
9821 * buffer.c (word_wrap): Doc fix.

9870 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
9871 Convert pctcpu and pctmem to Lisp float properly.
9872 Let the compiler fold better, as 100.0/0x8000 is exact.

9876 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

9891 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
9892 fields from Lisp_Object to bitfield. Adjust users accordingly.

9900 and 'double' in a couple of places.
9902 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9904 * xdisp.c (handle_stop): Detect whether we have overlay strings
9905 loaded by testing it->current.overlay_string_index to be
9906 non-negative, instead of checking whether n_overlay_strings is
9907 positive. (Bug#11587)
9909 2012-05-31 Chong Yidong <cyd@gnu.org>
9911 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

9917 * search.c (search_buffer): Remove calls to
9918 r_alloc_inhibit_buffer_relocation, as it is now called by
9919 maybe_unify_char, which was the cause of relocation of buffer text
9922 2012-05-31 Eli Zaretskii <eliz@gnu.org>
9924 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
9925 for the duration of call to load_charset, to avoid problems with
9926 callers of maybe_unify_char that access buffer text through C
9929 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
9930 decrement the inhibition flag, instead of just setting or
9933 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
9935 Remove obsolete '#define static' cruft.
9936 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
9937 This #undef was "temporary" in 2000; it is no longer needed
9938 now that '#define static' has gone away.

9940 (gray_bitmap_bits): Remove; no longer needed.
9941 All uses replaced with definiens.

9985 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
9986 Bug#9642, but explicitly check that the buffer the overlay would
9987 be moved to is live and rearrange lines to make sure that errors
9988 will not put the overlay in an inconsistent state.
9989 (Fdelete_overlay): Cosmetics.
9991 2012-05-28 Eli Zaretskii <eliz@gnu.org>
9993 * w32term.c (my_bring_window_to_top): New function.
9994 (x_raise_frame): Use handle returned by DeferWindowPos, which

10029 the others were already declared.
10031 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
10032 before checking whether it's out of range. Put the check inside

10038 * callproc.c (Fcall_process): Restore a line that was accidentally
10039 commented out in the 2011-02-13 change (bug#11547).
10041 2012-05-27 Eli Zaretskii <eliz@gnu.org>
10043 * lisp.h [REL_ALLOC]: Add prototypes for external functions
10044 defined on ralloc.c.
10046 * buffer.c [REL_ALLOC]: Remove prototypes of
10047 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
10048 they are now on lisp.h.
10050 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
10052 * search.c (search_buffer): Use it to inhibit relocation of buffer
10053 text while re_search_2 is doing its job, because re_search_2 is
10054 passed C pointers to buffer text. (Bug#11519)
10056 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
10057 Update value to 24.
10059 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
10060 state after an additional call to move_it_in_display_line_to, keep
10061 the values of it->max_ascent and it->max_descent found for the
10063 (pos_visible_p): Revert the comparison against bottom_y to what it
10064 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
10067 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10069 Fix coding-related core dumps with gcc -ftrapv.
10070 The code was computing A - B, where A and B are pointers, and B is
10071 random garbage. This can lead to core dumps on platforms that
10072 have special pointer registers, and it also leads to core dumps on
10073 x86-64 when compiled with gcc -ftrapv. The fix is to compute
10074 A - B only when B is initialized properly.
10075 * coding.c (coding_set_source, coding_set_destination): Return void.
10076 (coding_change_source, coding_change_destinations): New functions,
10077 with the old behaviors of coding_set_source and coding_set_destination.
10078 All callers that need an offset changed to use these new functions.
10080 2012-05-26 Glenn Morris <rgm@gnu.org>
10082 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
10084 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10086 Extend mouse support on W32 text-mode console.
10087 * xdisp.c (draw_row_with_mouse_face):
10088 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
10090 * w32console.c: Include window.h.
10091 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
10093 (initialize_w32_display): Initialize mouse-highlight data.
10095 * w32inevt.c: Include termchar.h and window.h.
10096 (do_mouse_event): Support mouse-autoselect-window. When the mouse
10097 moves, call note_mouse_highlight. If help_echo changed, call
10098 gen_help_event to produce help-echo message in the echo area.
10099 Call clear_mouse_face if mouse_face_hidden is set in the mouse
10102 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
10104 * lread.c (read1): Simplify slightly to avoid an overflow warning
10105 with GCC 4.7.0 on x86-64.
10107 2012-05-26 Eli Zaretskii <eliz@gnu.org>
10109 * bidi.c (bidi_mirror_char): Revert last change: an int is
10110 definitely wide enough here.
10112 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
10114 Fix integer width and related bugs (Bug#9874).

10116 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
10117 (string_bytes, check_sblock, allocate_string_data):

10124 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10125 (allocate_pseudovector):
10126 Use int, not EMACS_INT, where int is wide enough.
10127 (inhibit_garbage_collection, Fgarbage_collect):
10128 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10129 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
10130 int might not be wide enough.
10131 (bidi_cache_search, bidi_cache_find, bidi_init_it)
10132 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
10133 (bidi_at_paragraph_end, bidi_find_paragraph_start)

10137 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
10138 (Fkill_buffer, Fset_buffer_major_mode)
10139 (advance_to_char_boundary, Fbuffer_swap_text)

10146 (Foverlay_recenter, last_overlay_modification_hooks_used)
10147 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
10148 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10149 (validate_region): Omit unnecessary test for b <= e,
10150 since that's guaranteed by the previous test.
10151 (adjust_overlays_for_delete): Avoid pos + length overflow.
10152 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
10153 (report_overlay_modification):
10154 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10155 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
10156 Omit pointer cast, which isn't needed anyway, and doesn't work
10157 after the EMACS_INT -> ptrdiff_t change.
10158 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
10159 * buffer.h: Adjust decls to match defn changes elsewhere.
10160 (struct buffer_text, struct buffer):
10161 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10162 Use EMACS_INT, not int, where int might not be wide enough.
10163 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
10164 not int, to avoid needless 32-bit limit on 64-bit hosts.
10165 (exec_byte_code): Use tighter memory-full test, one that checks
10166 for alloca overflow. Don't compute the address of the object just
10167 before an array, as that's not portable. Use EMACS_INT, not
10168 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
10169 * callint.c (Fcall_interactively):
10170 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10171 * callproc.c (call_process_kill, Fcall_process):
10172 Don't assume pid_t fits into an Emacs fixnum.
10173 (call_process_cleanup, Fcall_process, child_setup):

10180 * casefiddle.c (casify_object, casify_region, operate_on_word)
10181 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
10182 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10183 (casify_object): Avoid integer overflow when overallocating buffer.
10184 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
10185 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
10186 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
10187 * category.h (CATEGORYP): Don't assume arg is nonnegative.
10188 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
10189 integers are now checked earlier. All uses replaced with XINT.
10191 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10192 For CCL_MapSingle, check that content and value are in int range.
10193 (ccl_driver, Fregister_code_conversion_map):
10194 Check that Vcode_version_map_vector is a vector.
10195 (resolve_symbol_ccl_program): Check that vector header is in range.
10196 Always copy the vector, so that we can check its contents reliably
10197 now rather than having to recheck each instruction as it's being
10198 executed. Check that vector words fit in 'int'.
10199 (ccl_get_compiled_code, Fregister_ccl_program)
10200 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
10201 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
10202 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
10203 contents are in range.
10204 (Fccl_execute_on_string): Check that status is in range.
10205 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
10206 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
10207 Accept and return EMACS_INT, not int, because callers can pass values
10208 out of 'int' range.
10209 (c_string_width, strwidth, lisp_string_width, chars_in_text)
10210 (multibyte_chars_in_text, parse_str_as_multibyte)

10212 (str_as_unibyte, str_to_unibyte, string_count_byte8)
10213 (string_escape_byte8, Fget_byte):
10214 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10215 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
10216 avoid mishandling large integers.
10217 * character.h: Adjust decls to match defn changes elsewhere.
10218 * charset.c (load_charset_map_from_file, find_charsets_in_text)
10219 (Ffind_charset_region):
10220 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10221 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
10222 (load_charset_map_from_vector, Fdefine_charset_internal):
10223 Don't assume fixnum fits in int.
10224 (load_charset_map_from_vector, Fmap_charset_chars):
10225 Remove now-unnecessary CHECK_NATNUMs.
10226 (Fdefine_charset_internal): Check ranges here, more carefully.
10227 Don't rely on undefined behavior with signed left shift overflow.
10228 Don't assume unsigned int fits into fixnum, or that fixnum fits
10229 into unsigned int. Don't require max_code to be a valid fixnum;
10230 that's not true for gb10830 4-byte on a 32-bit host. Allow
10231 invalid_code to be a cons, for the same reason. Require code_offset
10232 to be a character. Avoid int overflow if max_char is close
10234 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
10235 this is intended anyway and avoids some undefined behavior.
10236 (load_charset_map): Pass unsigned, not int, as 2nd arg of
10237 INDEX_TO_CODE_POINT, as that's what it expects.
10238 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
10239 * charset.h (DECODE_CHAR): Return int, not unsigned;
10240 this is what was intended anyway, and it avoids undefined behavior.
10241 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
10242 integer-overflow issues.
10243 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
10244 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
10245 where the argument is EMACS_INT, and this behavior is not intended.
10246 * chartab.c (Fmake_char_table, Fset_char_table_range)
10247 (uniprop_get_decoder, uniprop_get_encoder):
10248 Don't assume fixnum fits in int.
10249 * cmds.c (move_point): New function, that does the gist of
10250 Fforward_char and Fbackward_char, but does so while checking
10251 for integer overflow more accurately.
10252 (Fforward_char, Fbackward_char): Use it.
10253 (Fforward_line, Fend_of_line, internal_self_insert)
10254 (internal_self_insert):
10255 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
10256 Fix a FIXME, by checking for integer overflow when calculating
10257 target_clm and actual_clm.

10288 (get_translation, handle_composition_annotation, consume_chars):
10289 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
10290 (consume_chars): Rewrite to not calculate an address outside buffer.
10291 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
10292 Don't access memory outside of the args array.
10293 (Fdefine_coding_system_internal): Check for charset-id overflow.
10294 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
10295 result of ENCODE_CHAR.

10314 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
10315 Do not attempt to compute the address of the object just before a
10316 buffer; this is not portable.
10318 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

11046 (report_error, report_error_1, make_hdr, copy_sym)
11047 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
11048 Make arguments const char *, not char *, to avoid violations of C

11051 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11053 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
11054 already have overlays loaded.
11055 (handle_single_display_spec): Before returning without displaying
11056 fringe bitmap, synchronize the bidi iterator with the main display
11057 iterator, by calling iterate_out_of_display_property.
11058 (iterate_out_of_display_property): Detect buffer iteration by
11059 testing that it->string is a Lisp string.
11060 (get_next_display_element): When the current object is exhausted,
11061 and there's something on it->stack, call set_iterator_to_next to
11062 proceed with what's on the stack, instead of returning zero.
11063 (set_iterator_to_next): If called at the end of a Lisp string,
11064 proceed to consider_string_end without incrementing string
11065 position. Don't increment display vector index past the end of

11067 (pos_visible_p): Don't report a position visible when move_it_to
11068 stopped at the last line of window, which happens to be scanned
11069 backwards by the bidi iteration. (Bug#11464)
11071 2012-05-14 Eli Zaretskii <eliz@gnu.org>
11073 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
11074 and right-margin display specs even if the spec is invalid or we
11075 are on a TTY, and thus unable to display on the fringes.
11076 That's because the text with the property will not be displayed anyway,
11077 so we need to signal to the caller that this is a "replacing"
11078 display spec. This fixes display when the spec is invalid or we
11081 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
11083 * unexaix.c (make_hdr): Fix typo in prototype.
11084 This bug broke the build on AIX. Problem reported by Gilles Pion.

11101 * Makefile.in (MKDIR_P): New, set by configure.
11102 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
11104 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
11106 Remove unused function hourglass_started.
11107 * dispextern.h (hourglass_started):
11108 * w32fns.c (hourglass_started):
11109 * xdisp.c (hourglass_started): Remove.
11111 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
11113 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
11114 Update dependencies.
11116 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
11118 * xgselect.c (xg_select): Put maxfds+1 into a var.
11119 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
11121 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
11123 2012-05-10 Dave Abrahams <dave@boostpro.com>
11125 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
11126 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
11128 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
11130 * dbusbind.c (xd_registered_buses): New internal Lisp object.
11131 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
11132 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
11133 Initialize xd_registered_buses.
11135 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
11137 Untag more efficiently if USE_LSB_TAG.
11138 This is based on a proposal by YAMAMOTO Mitsuharu in
11139 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
11140 For an admittedly artificial (nth 8000 longlist) benchmark on
11141 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
11142 Emacs's overall text size by 1%.
11143 * lisp.h (XUNTAG): New macro.
11144 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
11145 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
11146 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
11147 * eval.c (Fautoload):
11148 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
11149 * frame.h (XFRAME): Use XUNTAG.
11151 Port recent dbusbind.c changes to 32-bit --with-wide-int.
11152 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
11153 Remove unportable assumptions about print widths of types like
11155 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
11156 intptr_t when converting between pointer and integer, to avoid GCC
11157 warnings about wrong width.
11159 2012-05-09 Eli Zaretskii <eliz@gnu.org>
11161 * w32proc.c (new_child): Force Windows to reserve only 64KB of
11162 stack for each reader_thread, instead of defaulting to 8MB
11163 determined by the linker. This avoids failures in creating
11164 subprocesses on Windows 7, see the discussion in this thread:
11165 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
11167 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
11169 Fix up display of the *Minibuf-0* buffer in the mini window.
11170 * keyboard.c (read_char): Don't clear the echo area if there's no
11172 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
11173 contents of *Minibuf-0*) if there's no message displayed in its stead.
11175 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
11177 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
11180 2012-05-06 Chong Yidong <cyd@gnu.org>
11182 * lisp.mk (lisp): Update.
11184 2012-05-05 Jim Meyering <meyering@redhat.com>
11186 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
11188 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
11190 * data.c (PUT_ERROR): New macro.
11191 (syms_of_data): Use it. Add new error type `user-error'.
11192 * undo.c (user_error): New function.
11193 (Fprimitive_undo): Use it.
11194 * print.c (print_error_message): Adjust print style for `user-error'.
11195 * keyboard.c (user_error): New function.
11196 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
11198 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
11200 Do not limit current-time-string to years 1000..9999.
11201 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
11202 (Fcurrent_time_string): Support any year that is supported by the
11203 underlying localtime representation. Don't use asctime, as it
11204 has undefined behavior for years outside the range -999..9999.
11206 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
11208 Fix race conditions involving setenv, gmtime, localtime, asctime.
11209 Without this fix, interrupts could mess up code that uses these
11210 nonreentrant functions, since setting TZ invalidates existing
11211 tm_zone or tzname values, and since most of these functions return
11212 pointers to static storage.
11213 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
11214 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
11215 Grow the critical sections to include not just invoking
11216 localtime/gmtime, but also accessing these functions' results
11217 including their tm_zone values if any, and any related TZ setting.
11218 (format_time_string): Last arg is now struct tm *, not struct tm **,
11219 so that the struct tm is saved in the critical section.
11220 All callers changed. Simplify allocation of initial buffer, partly
11221 motivated by the fact that memory allocation needs to be outside
11222 the critical section.
11224 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
11226 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
11227 with RESET_INTERVAL.
11229 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
11230 Remove duplicated buffer name initialization.
11232 2012-05-02 Jim Meyering <jim@meyering.net>
11234 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
11236 * xfns.c (x_window): Use xstrdup (Bug#11375).
11238 2012-05-02 Eli Zaretskii <eliz@gnu.org>
11240 * xdisp.c (pos_visible_p): If already at a newline from the
11241 display string before the 'while' loop, don't walk back the glyphs
11242 from it3.glyph_row. Solves assertion violation when the display
11243 string begins with a newline (egg.el). (Bug#11367)
11245 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
11247 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
11250 2012-05-01 Glenn Morris <rgm@gnu.org>
11252 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
11253 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
11254 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
11255 All were removed before 23.1.
11257 * dispnew.c: Remove HAVE_LIBNCURSES test;
11258 it is always true on relevant platforms.
11260 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
11261 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
11263 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
11265 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
11267 * .gdbinit (xpr): Remove checks for no longer existing misc types.
11268 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
11271 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
11273 Do not avoid creating empty evaporating overlays (Bug#9642).
11274 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
11275 That is, do not delete an evaporating overlay if it becomes
11276 empty after its bounds are adjusted to fit within its buffer.
11277 This fix caused other problems, and I'm reverting it until we get
11278 to the bottom of them.
11280 2012-04-27 Chong Yidong <cyd@gnu.org>
11282 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
11284 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11286 * xdisp.c (pos_visible_p): If the window start position is beyond
11287 ZV, start the display from buffer beginning. Prevents assertion
11288 violation in init_iterator when the minibuffer window is scrolled
11289 via the scroll bar.
11291 * window.c (window_scroll_pixel_based): Likewise.
11293 2012-04-27 Chong Yidong <cyd@gnu.org>
11295 * keymap.c (where_is_internal): Doc fix (Bug#10872).
11297 2012-04-27 Glenn Morris <rgm@gnu.org>
11299 * fileio.c (Fcopy_file, Fset_file_selinux_context):
11300 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
11302 2012-04-27 Eli Zaretskii <eliz@gnu.org>
11304 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
11305 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
11307 2012-04-26 Eli Zaretskii <eliz@gnu.org>
11309 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
11310 display element, check also the underlying string or buffer
11311 character. (Bug#11341)
11313 * w32menu.c: Include w32heap.h.
11314 (add_menu_item): If the call to AppendMenuW (via
11315 unicode_append_menu) fails, disable Unicode menus only if we are
11316 running on Windows 9X/Me.
11318 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
11320 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
11321 (xgetint): Add missing shift for LSB tags.
11323 2012-04-24 Martin Rudalics <rudalics@gmx.at>
11325 * keyboard.c (read_char): Don't wipe echo area for select window
11326 events: These might get delayed via `mouse-autoselect-window'
11329 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
11331 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
11332 manipulation of :loaded-from data.
11334 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
11336 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
11337 now a cons (bug#11311).
11339 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
11341 Do not create empty overlays with the evaporate property (Bug#9642).
11342 * buffer.c (Fmove_overlay): Delete an evaporating overlay
11343 if it becomes empty after its bounds are adjusted to fit within
11344 its buffer. Without this fix, in a nonempty buffer (let ((o
11345 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
11346 yields an empty overlay that has the evaporate property, which is
11347 not supposed to happen.
11349 Fix minor GTK3 problems found by static checking.
11350 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
11351 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11352 (struct _EmacsFixedClass, emacs_fixed_get_type):
11353 Move decls here from emacsgtkfixed.h, since they needn't be public.

11355 (emacs_fixed_class_init): Omit unused local.
11356 (emacs_fixed_child_type): Remove; unused.

11358 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
11359 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
11360 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
11361 (EMACS_FIXED_GET_CLASS): Remove; unused.
11362 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
11364 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
11365 Problem reported by Juanma Barranquero for Windows -Wunused-function.
11367 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
11369 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
11370 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
11371 (__malloc_size_t, __malloc_ptrdiff_t):
11372 Remove. All uses removed, replaced by the definiens if needed,
11373 since we can assume C89 or better now.
11374 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
11375 (protect_malloc_state, align, get_contiguous_space)
11376 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

11381 (special_realloc, _realloc_internal_nolock, _realloc_internal)
11382 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
11383 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
11384 Define using prototypes, not old style.
11385 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
11386 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
11387 (align): Don't assume that signed integer overflow wraps around.
11388 Omit unused local var.
11389 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

11391 Omit no-longer-needed casts.
11392 (valloc): Use getpagesize, not __getpagesize.
11393 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
11394 (struct hdr): The 'magic' member is now size_t, not unsigned long.
11396 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
11398 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
11400 Move functions from C to Lisp. Make non-blocking method calls
11401 the default. Implement further D-Bus standard interfaces.

11431 (Fdbus_method_return_internal, Fdbus_method_error_internal)
11432 (Fdbus_send_signal, Fdbus_register_service)
11433 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

11446 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
11447 Do not assume ptrdiff_t is the same width as 'int'.
11449 * alloc.c: Handle unusual debugging option combinations.
11450 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
11451 since the two debugging options are incompatible.
11452 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
11454 (mem_init, mem_insert, mem_insert_fixup):
11455 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

11465 (list_system_processes, system_process_attributes) [__FreeBSD__]:
11466 Use Emacs indenting style more consistently. Avoid some casts.
11467 Use 'double' consistently rather than mixing 'float' and 'double'.
11469 2012-04-21 Eduard Wiebe <usenet@pusto.de>
11471 * sysdep.c (list_system_processes, system_process_attributes):

11506 row, return zero immediately.
11507 (try_cursor_movement): If inside continuation line, don't back up
11508 farther than the first row after the header line, if any.
11509 Don't consider the header-line row as "partially visible", even if
11510 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

11548 New extern decls, to avoid calling undeclared functions.
11549 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
11550 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
11551 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
11552 (NEED_MEM_INSERT): New macro.
11553 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
11554 Remove one incorrect comment and fix another.

11568 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
11569 Remove decls. This fixes an "It stinks!".
11571 * alloc.c (which_symbols): Fix alignment issue / type clash.
11573 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
11575 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
11576 (struct Lisp_Misc_Any): Likewise.
11577 (struct Lisp_Free): Likewise.
11578 * alloc.c (union aligned_Lisp_Symbol): Define.

11588 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
11589 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
11590 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
11591 * s/netbsd.h, s/sol2-6.h:
11592 Remove definition of GC_MARK_STACK, since the default now works.
11593 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
11594 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
11595 no longer the default.
11596 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
11598 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
11600 * lread.c (lisp_file_lexically_bound_p):
11601 Fix hang at ";-*-\n" (bug#11238).
11603 2012-04-14 Eli Zaretskii <eliz@gnu.org>
11605 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

11617 2012-04-13 Reuben Thomas <rrt@sc3d.org>
11619 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
11621 2012-04-11 Daniel Colascione <dancol@dancol.org>
11623 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
11624 against is gone. It's better to use vfork now so that when Cygwin
11625 gains a new, working vfork, we use it automatically (bug#10398).
11627 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

11645 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
11647 * w32.c (w32_delayed_load): Record the full path of the library
11648 being loaded (bug#10424).
11650 2012-04-09 Glenn Morris <rgm@gnu.org>
11652 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
11653 not just in the obarray, before snarfing them. (Bug#11036)
11655 * Makefile.in ($(leimdir)/leim-list.el):
11656 Pass EMACS rather than BUILT_EMACS.
11658 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
11660 * process.c (make_process):
11661 * process.h: Add integer `gnutls_handshakes_tried' member to

11670 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
11671 attempts per process (connection).
11673 2012-04-09 Chong Yidong <cyd@gnu.org>
11675 * eval.c (Fuser_variable_p, user_variable_p_eh)
11676 (lisp_indirect_variable): Functions deleted.
11677 (Fdefvar): Caller changed.
11679 * callint.c (Finteractive, Fcall_interactively):
11680 * minibuf.c (Fread_variable): Callers changed.
11682 2012-04-09 Eli Zaretskii <eliz@gnu.org>
11684 * xdisp.c (set_cursor_from_row): If the display string appears in
11685 the buffer at position that is closer to point than the position
11686 after the display string, display the cursor on the first glyph of
11687 the display string. Fixes cursor display when a 'display' text
11688 property immediately follows invisible text. (Bug#11094)
11690 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
11692 composite.c: use 'double' consistently
11693 * composite.c (get_composition_id): Use 'double' consistently
11694 instead of converting 'float' to 'double' and vice versa; this is
11695 easier to understand and avoids a GCC warning.
11697 2012-04-09 Glenn Morris <rgm@gnu.org>
11699 * Makefile.in: Generate leim-list with bootstrap-emacs, in
11700 preparation for dumping it with emacs. (Bug#4789)

11721 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
11722 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
11723 (mark_memory): Mark Lisp_Objects only if pointers might hide in
11724 objects, as mark_maybe_pointer will catch them otherwise.
11725 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
11726 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

11735 Support building on MS-Windows with libxml2.
11737 * makefile.w32-in (OBJ2): Add xml.$(O).
11738 (GLOBAL_SOURCES): Add xml.c.
11739 ($(BLD)/xml.$(O)): New dependency list.
11741 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
11742 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
11743 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
11744 [!WINDOWSNT]: New macros.
11745 (init_libxml2_functions, libxml2_loaded_p): New functions.
11746 (parse_region): Call fn_xmlCheckVersion instead of using the macro
11747 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
11748 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
11749 Calls xmlCleanupParser only if libxml2 was loaded (or statically
11751 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
11752 Call init_libxml2_functions before calling libxml2 functions.
11753 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
11755 * emacs.c: Don't include libxml/parser.h.
11756 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
11757 xmlCleanupParser directly.
11759 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
11761 2012-04-07 Eli Zaretskii <eliz@gnu.org>
11763 * indent.c (Fvertical_motion): If there is a display string at
11764 point, use it.vpos to compute how many lines to backtrack after
11765 move_it_to point. (Bug#11133)
11767 2012-04-06 Eli Zaretskii <eliz@gnu.org>
11769 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
11770 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
11771 about subtle differences between FETCH_CHAR* and STRING_CHAR*
11772 macros related to unification of CJK characters. For the details,
11773 see the discussion following the message here:
11774 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
11776 2012-04-04 Chong Yidong <cyd@gnu.org>
11778 * keyboard.c (Vdelayed_warnings_list): Doc fix.
11780 2012-04-01 Eli Zaretskii <eliz@gnu.org>
11782 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

11790 2012-03-31 Eli Zaretskii <eliz@gnu.org>
11792 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
11793 position we get to after a call to move_it_to fails the
11794 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
11795 only if we wind up in a string from display property. (Bug#11063)
11797 * window.c (Fdelete_other_windows_internal): Invalidate the row
11798 and column information about mouse highlight, so that redisplay
11799 restores it after reallocating the glyph matrices. (Bug#7464)
11801 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
11802 string comes from a `display' text property, use the buffer
11803 position of that property as if we actually saw that position in
11805 (move_it_by_lines): Remove the assertion that
11806 "it->current_x == 0 && it->hpos == 0" which can be legitimately
11807 violated when there's a before-string at the beginning of a line.
11810 2012-03-30 Eli Zaretskii <eliz@gnu.org>
11812 * xdisp.c (append_space_for_newline): If the default face was

11814 (extend_face_to_end_of_line): Use the remapped default face for
11815 extending the face to the end of the line.
11816 (display_line): Call extend_face_to_end_of_line when the default
11817 face was remapped. (Bug#11068)
11819 2012-03-29 Eli Zaretskii <eliz@gnu.org>
11821 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

11839 * keyboard.c (Vselection_inhibit_update_commands): New variable.
11840 (command_loop_1): Use it; inhibit selection update for

11847 2012-03-25 Kenichi Handa <handa@m17n.org>
11849 * dispextern.h (struct glyph): Change the bit length of
11850 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
11852 2012-03-24 Eli Zaretskii <eliz@gnu.org>
11854 * s/ms-w32.h (tzname): Include time.h before redirecting to

11863 !SYNC_INPUT. (Bug#11080)
11865 2012-03-23 Eli Zaretskii <eliz@gnu.org>
11867 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
11868 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
11869 when fetching a multibyte character consumes more bytes than
11870 CHAR_BYTES returns, due to unification of CJK characters in
11871 string_char. (Bug#11073)
11873 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
11875 * process.c (wait_reading_process_output): Handle pty disconnect
11876 by refraining from sending oneself a SIGCHLD (bug#10933).
11878 2012-03-22 Chong Yidong <cyd@gnu.org>
11880 * dispextern.h (struct it): New member string_from_prefix_prop_p.

11910 that is not from display property, accept the row as a "cursor
11911 row" if one of the string's character has a non-nil `cursor'
11912 property. Fixes cursor positioning when there are newlines in
11913 overlay strings, e.g. in icomplete.el. (Bug#11035)
11915 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
11917 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
11919 2012-03-12 Chong Yidong <cyd@gnu.org>
11921 * eval.c (inhibit_lisp_code): Rename from
11922 inhibit_window_configuration_change_hook; move from window.c.
11924 * xfns.c (unwind_create_frame_1, Fx_create_frame):
11925 * window.c (run_window_configuration_change_hook)
11926 (syms_of_window): Callers changed.
11928 2012-03-11 Chong Yidong <cyd@gnu.org>
11930 * keymap.c (Fkey_description): Doc fix (Bug#9700).

11941 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
11943 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
11945 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
11946 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
11949 2012-03-03 Glenn Morris <rgm@gnu.org>
11951 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
11953 2012-03-02 Eli Zaretskii <eliz@gnu.org>

11956 position past the first glyph_row that ends at ZV. (Bug#10902)
11957 (redisplay_window, next_element_from_string): Fix typos in
11959 (redisplay_window): Pass to move_it_vertically the margin in
11960 pixels, not in screen lines.
11962 2012-03-02 Glenn Morris <rgm@gnu.org>
11964 * buffer.c (buffer-list-update-hook): Doc fix.
11966 2012-02-29 Eli Zaretskii <eliz@gnu.org>
11968 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
11969 push_it before setting up the iterator for the first overlay
11970 string, even if we have an empty string loaded.
11971 (next_overlay_string): If there's an empty string on the iterator
11972 stack, pop the stack. (Bug#10903)
11974 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
11976 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
11977 Suggested by Stefan Monnier in
11978 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
11979 * alloc.c (widen_to_Lisp_Object): New static function.
11980 (mark_memory): Also mark Lisp_Objects by fetching pointer words
11981 and widening them to Lisp_Objects. This would work even if
11982 USE_LSB_TAG is defined and wide integers are used, which might
11983 happen in a future version of Emacs.
11985 2012-02-25 Chong Yidong <cyd@gnu.org>
11987 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
11990 * xselect.c (Fx_selection_exists_p): Doc fix.

12027 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
12028 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
12029 It's useless in that case, and it can cause problems on hosts
12030 that allocate halves of EMACS_INT values separately.
12031 Reported by Dan Horák. Diagnosed by Andreas Schwab in
12032 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
12033 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
12034 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
12035 it avoids undefined behavior on hosts where shifting right by more
12036 than the word width has undefined behavior.
12038 2012-02-19 Chong Yidong <cyd@gnu.org>
12040 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
12041 (Funhandled_file_name_directory, Ffile_name_as_directory)

12083 * window.c (Fdelete_window_internal): Invalidate the mouse
12084 highlight (Bug#9904).

12122 2012-02-07 Glenn Morris <rgm@gnu.org>
12124 * image.c (Fimagemagick_types): Doc fix.
12126 * image.c (imagemagick-render-type): Change it from a lisp object

12162 * character.c (char_width): Return EMACS_INT, not int.
12163 (char_width, c_string_width): Check for overflow when

12190 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to

12197 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
12198 first 2 arguments are identical. This makes inserting large

12653 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
12654 verifies glyph row's hash code--we have just reallocated the

12820 is set, removing the need for VIRT_ADDRESS_VARIES.
12821 (PURE_P): Use a more-efficient implementation that needs just one

12838 behave as if the cursor position were at the window margin.
12840 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
12841 and the cursor position is out of bounds, behave as if the cursor
12842 position were at the window margin. (Bug#10075)
12844 2011-11-18 Chong Yidong <cyd@gnu.org>
12846 * window.c (Fwindow_combination_limit): Make first argument

12868 compute_line_metrics.
12869 (compute_line_metrics): Call row_hash, instead of computing the
12872 * dispnew.c (verify_row_hash): Call row_hash for computing the
12873 hash code of a row, instead of duplicating code from xdisp.c.
12875 * dispextern.h (row_hash): Add prototype.
12877 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
12879 * frame.c (delete_frame): Don't delete the terminal when the last

12928 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
12929 with user-defined heap size. Bump the default size of the temacs

12933 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
12934 current_matrix and desired_matrix. (Bug#9990)
12935 (verify_row_hash) [XASSERTS]: New function.

12980 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
12982 Avoid some portability problems by eschewing 'extern inline' functions.
12983 The trivial performance wins aren't worth the portability hassles; see
12984 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
12986 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

13035 This is also needed for porting to any host where GC_MARK_STACK is
13036 not GC_MAKE_GCPROS_NOOPS.
13037 (which_symbols): Use it.

13052 * xmenu.c (cleanup_widget_value_tree): New function.
13053 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
13054 calling free_menubar_widget_value_tree directly (Bug#9830).

13060 (window_box_width, window_box_left, window_box_left_offset)
13061 (window_box_right, window_box_right_offset): Declare extern.
13062 Otherwise, these inline functions do not conform to C99 and
13063 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
13064 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
13065 * intervals.c (adjust_intervals_for_insertion)

13068 (static_offset_intervals): Remove.
13069 (offset_intervals): Rewrite using the old contents of
13070 static_offset_intervals. The old version didn't conform to C99
13071 because an extern inline function contained a reference to an
13072 identifier with static linkage.
13074 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
13076 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

13094 (Fwindow_vscroll): Doc fix.
13095 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
13096 argument, since it makes no sense to pass a live window and for
13097 consistency with window-child.

13138 official. Move initialization of image_cache_refcount and
13139 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

13307 (w32font_open_internal, compute_metrics):
13308 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
13309 instead of calling the "wide" APIs directly.

13385 * editfns.c: Rewrite current-time-zone so that it invokes
13386 the equivalent of (format-time-string "%Z") to get the time zone name.
13387 This fixes a bug when the time zone name contains characters that
13388 need converting from the system time locale to Emacs internal format.
13389 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
13390 that patch fixed format-time-string to do the conversion, but
13391 I forgot to fix current-time-zone.
13392 (format_time_string): New function, containing most of
13393 what Fformat_time_string used to contain.
13394 (Fformat_time_string): Rewrite in terms of format_time_string.
13395 This doesn't change this function's behavior.
13396 (current-time-zone): Rewrite to use format_time_string.
13397 This fixes the bug reported by Michael Schierl in
13398 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
13399 Jason Rumney's 2007-06-07 change worked around this bug, but
13401 * systime.h (tzname, timezone): Remove no-longer-used declarations.
13403 2011-10-19 Eli Zaretskii <eliz@gnu.org>
13405 * xdisp.c (start_display): If the character at POS is displayed
13406 via a display vector, reset IT->current.dpvec_index to zero.
13407 (try_window_reusing_current_matrix): If a line ends in a display
13408 vector or the next line starts in a display vector, continue
13409 redrawing the window even though the character position of
13410 start_row was reached.
13413 2011-10-18 Chong Yidong <cyd@gnu.org>
13415 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
13416 with nobreak-char-display too.
13418 2011-10-18 Eli Zaretskii <eliz@gnu.org>
13420 Fix part 3 of bug#9771.
13421 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
13422 (bidi_resolve_neutral): Don't enter the expensive loop looking for
13423 non-neutral characters if the current character is a paragraph
13424 separator (a.k.a. Newline). This avoids running the same
13425 expensive loop twice, once when we consume the preceding newline
13426 and the other time when the line actually needs to be displayed.
13427 Avoid the loop when we see neutrals on the base embedding level
13428 following a character whose directionality is the same as the
13429 paragraph's. This avoids running the expensive loop when a line
13430 ends in a long sequence of neutrals, like control characters.
13431 Add assertion against STRONG_AL type. Slightly rearrange code
13432 that determines the type of a neutral given the first non-neutral
13434 (bidi_level_of_next_char): Set next_en_pos to zero when
13435 invalidating its info.
13437 2011-10-17 Eli Zaretskii <eliz@gnu.org>
13439 * xdisp.c (push_display_prop): Determine whether to record string
13440 or buffer position by IT->string, not by IT->method. Allow
13441 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
13442 (move_it_vertically_backward): Don't look for character position
13443 immediately after the newline when in a continuation line.
13446 2011-10-15 Martin Rudalics <rudalics@gmx.at>
13448 * window.c (coordinates_in_window): Rewrite and delabelize
13449 vertical border check. (Bug#5357) (Bug#9618)
13451 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
13453 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
13454 errors in XSetWindowBorder (bug#9310).
13456 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
13458 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
13459 avoid crash when xmalloc overrun checking is enabled.
13461 2011-10-13 Eli Zaretskii <eliz@gnu.org>
13463 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
13464 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
13465 cursor motion with <left> and <right> arrow keys.
13467 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
13468 some callers set that themselves.
13470 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13472 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
13473 display string and the previous row comes from the same string and
13474 is empty. (Bug#9739) (Bug#9738)
13476 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
13478 * doc.c (get_doc_string): Encode file name (bug#9735).
13480 2011-10-12 Eli Zaretskii <eliz@gnu.org>
13482 * bidi.c (bidi_level_of_next_char):
13483 * xdisp.c (get_visually_first_element): Remove old incorrect
13484 comments regarding the Unicode Line Separator character.
13486 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
13488 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
13490 * alloc.c (Fgc_status): Do not access beyond zombies array
13491 boundary if nzombies > MAX_ZOMBIES.
13492 * alloc.c (dump_zombies): Add missing format specifier.
13494 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
13496 * xdisp.c (set_cursor_from_row): Simplify conditionals,
13497 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
13499 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
13500 Some packages use them to denote characters with modifiers.
13502 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
13504 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
13505 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
13506 matching a pp-number. Rename parameter var to var1.
13508 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
13510 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
13512 2011-10-08 Glenn Morris <rgm@gnu.org>
13514 * callint.c (Fcall_interactively): Give a more explicit error for the
13515 'c' case with a non-character input. (Bug#8479)
13517 2011-10-08 Eli Zaretskii <eliz@gnu.org>
13519 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
13521 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
13522 lines that are hscrolled on the left.
13524 * dispnew.c (buffer_posn_from_coords): Account for a possible
13525 presence of header-line. (Bug#4426)
13527 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
13529 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
13530 Don't advertise functionality which we discourage or doesn't work.
13532 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
13534 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
13535 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
13536 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
13537 this makes Emacs dump core during garbage collection on rare
13538 occasions. sizeof is obviously inferior to offsetof here, so
13539 stick with offsetof.
13540 (GC_POINTER_ALIGNMENT): New macro.
13541 (mark_memory): Omit 3rd (offset) arg; caller changed.
13542 Don't assume EMACS_INT alignment is the same as pointer alignment.
13544 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
13546 * keyboard.c (read_key_sequence_remapped): New var.
13547 (read_key_sequence): Compute remapping in the right buffer.
13548 (command_loop_1): Use read_key_sequence's remapping directly.
13550 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
13552 * dired.c (file_name_completion): Don't expand file name.
13553 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
13554 before checking file name handler.
13556 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
13557 they've been requested explicitly (bug#9591).
13559 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
13561 * keymap.c (Fsingle_key_description): Use make_specified_string
13562 instead of build_string to build string from push_key_description.
13565 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13567 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
13568 This fixes a Y2038 bug on 64-bit hosts.
13569 * buffer.c (reset_buffer):
13570 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
13571 (Fclear_buffer_auto_save_failure):
13572 Use 0, not -1, to represent an unset failure time, since time_t
13573 might not be signed.
13575 Remove dependency on glibc malloc internals.
13576 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13577 Move back here from lisp.h, but with their new implementations.
13578 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13579 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
13580 * charset.c (charset_table_init): New static var.
13581 (syms_of_charset): Use it instead of xmalloc. This removes a
13582 dependency on glibc malloc internals. See Eli Zaretskii's comment in
13583 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
13584 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13585 Move back to alloc.c.
13586 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13587 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
13589 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
13591 * nsterm.m (windowDidResize): Call x_set_window_size only when
13592 ns_in_resize is true. Otherwise set pixelwidth/height and
13593 call change_frame_size (Bug#9628).
13595 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
13597 Port --enable-checking=all to Fedora 14 x86-64.
13598 * charset.c (syms_of_charset): Also account for glibc malloc's
13599 internal overhead when calculating the initial malloc maximum.
13601 Port --enable-checking=all to Fedora 14 x86.
13602 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13604 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
13605 (overrun_check_realloc, overrun_check_free):
13606 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
13607 That way, xmalloc returns a properly-aligned pointer even if
13608 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
13609 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
13610 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
13611 into account when calculating the initial malloc maximum.
13612 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
13613 Move here from alloc.c, so that charset.c can use it too.
13614 Properly align; the old code wasn't right for common 32-bit hosts
13615 when configured with --enable-checking=all.
13616 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
13617 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
13619 2011-09-29 Eli Zaretskii <eliz@gnu.org>
13621 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
13624 2011-09-28 Eli Zaretskii <eliz@gnu.org>
13626 * xdisp.c (compute_display_string_end): If there's no display
13627 string at CHARPOS, return -1.
13629 * bidi.c (bidi_fetch_char): When compute_display_string_end
13630 returns a negative value, treat the character as a normal
13631 character not covered by a display string. (Bug#9624)
13633 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
13635 * lread.c (Fread_from_string): Fix typo in docstring.
13637 2011-09-27 Eli Zaretskii <eliz@gnu.org>
13639 * xdisp.c (handle_invisible_prop): If invisible text ends on a
13640 newline, reseat the iterator instead of bidi-iterating there one
13641 character at a time. (Bug#9610)
13642 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
13643 TO_CHARPOS if the bidi iterator is at base embedding level.
13645 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
13647 * lread.c (readevalloop): Use correct code for NBSP.
13648 (read1): Likewise. (Bug#9608)
13650 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
13652 * dbusbind.c (Fdbus_register_signal): When service is not
13653 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
13655 2011-09-25 Glenn Morris <rgm@gnu.org>
13657 * buffer.c (truncate-lines): Doc fix.
13659 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
13661 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
13662 (Fset_window_next_buffers): Doc fix.
13664 2011-09-24 Glenn Morris <rgm@gnu.org>
13666 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
13668 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
13670 Fix minor problems found by static checking.
13671 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
13672 * indent.c (Fvertical_motion): Fix == vs = typo.
13674 2011-09-24 Eli Zaretskii <eliz@gnu.org>
13676 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
13677 Default value is now t. Doc fix.
13679 * indent.c (Fvertical_motion): Compute and apply the overshoot
13680 logic when moving up, not only when moving down. Fix the
13681 confusing name and values of the it_overshoot_expected variable;
13682 logic changes accordingly. (Bug#9254) (Bug#9549)
13684 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
13685 CHARPOS is covered by a display string which includes newlines.
13686 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
13687 is covered by a display string with embedded newlines.
13689 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
13691 * dbusbind.c (Fdbus_register_signal): Add match rule to
13692 Vdbus_registered_objects_table. (Bug#9581)
13693 (Fdbus_register_method, Vdbus_registered_objects_table):
13696 2011-09-24 Jim Meyering <meyering@redhat.com>
13698 do not ignore write error for any output size
13699 The previous change was incomplete.
13700 While it makes emacs --batch detect the vast majority of stdout
13701 write failures, errors were still ignored whenever the output size is
13702 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
13703 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
13704 && echo FAIL: ignored write error
13705 FAIL: ignored write error
13706 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
13707 && echo FAIL: ignored write error
13708 FAIL: ignored write error
13709 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
13711 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
13713 * emacs.c (Fkill_emacs): In noninteractive mode exit
13714 non-successfully if a write error occurred on stdout. (Bug#9574)
13716 2011-09-21 Eli Zaretskii <eliz@gnu.org>
13718 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
13721 * dispextern.h (struct it): Update the comment documenting what
13724 2011-09-20 Eli Zaretskii <eliz@gnu.org>
13726 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
13727 a display string, extend search for cursor position to end of row.
13728 (find_row_edges): If the row ends in a newline from a display
13729 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
13730 Handle the case of a display string with multiple newlines.
13731 (Fcurrent_bidi_paragraph_direction): Fix search for previous
13732 non-empty line. Fixes confusing cursor motion with arrow keys at
13733 the beginning of a line that starts with whitespace.
13735 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13737 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
13740 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
13742 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
13743 boolean (Bug#9154).
13745 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13747 * xdisp.c (display_line): Record maximum and minimum buffer
13748 positions even if no glyphs were produced (e.g., by a zero-width
13749 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
13750 buffer positions that will be removed from the glyph row because
13752 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
13753 column is beyond frame width: don't subtract 1 "pixel" when
13754 computing width of the stretch.
13755 (reseat_at_next_visible_line_start): Undo the change made on
13756 2011-09-17 that saved paragraph information and restored it after
13757 the call to `reseat'. (Bug#9545)
13759 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
13761 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
13762 and turn window cursor on if cleared (Bug#9415).
13764 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
13766 * search.c (boyer_moore): Take unibyte characters from pattern
13767 literally. (Bug#9458)
13769 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13771 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
13773 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
13775 Fix minor problem found by static checking.
13776 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
13777 initialized, to pacify gcc -Wuninitialized.
13779 * fileio.c: Report proper errno when syscall falls.
13780 (Finsert_file_contents): Save and restore errno,
13781 so that report_file_error outputs the correct diagnostic.
13782 (Fwrite_region) [CLASH_DETECTION]: Likewise.
13784 2011-09-18 Eli Zaretskii <eliz@gnu.org>
13786 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
13788 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13790 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
13791 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
13793 2011-09-17 Eli Zaretskii <eliz@gnu.org>
13795 * xdisp.c (reseat_at_next_visible_line_start): Keep information
13796 about the current paragraph and restore it after the call to reseat.
13798 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
13799 (bidi_find_paragraph_start): Search back for paragraph beginning
13800 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
13801 (bidi_move_to_visually_next): Only trigger paragraph-related
13802 computations when the last character is a newline or at EOB, not
13803 just any NEUTRAL_B. (Bug#9470)
13805 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
13806 truncated lines if point is covered by a display string. (Bug#9524)
13808 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
13810 * xselect.c: Relax test for outgoing X longs (Bug#9498).
13811 (cons_to_x_long): New function.
13812 (lisp_data_to_selection_data): Use it. Correct the test for
13813 short-versus-long data; it was negated. Break out of vector
13814 loop, for efficiency, when a long datum is discovered.
13816 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
13818 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
13820 2011-09-16 Eli Zaretskii <eliz@gnu.org>
13822 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
13823 GCC PR/17406) by declaring this function with external scope.
13825 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13827 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

13830 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
13832 * editfns.c (Fformat): Correctly handle text properties on "%%".
13834 2011-09-15 Eli Zaretskii <eliz@gnu.org>
13836 * xterm.c (x_draw_composite_glyph_string_foreground):
13837 * w32term.c (x_draw_composite_glyph_string_foreground):
13838 * term.c (encode_terminal_code):
13839 * composite.c (composition_update_it, get_composition_id):
13840 * xdisp.c (get_next_display_element)
13841 (fill_composite_glyph_string): Add comments about special meaning
13842 of TAB characters in a composition.
13844 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
13846 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
13847 This occurs when processing a multibyte format.
13848 Problem reported by Wolfgang Jenker.
13850 2011-09-15 Johan Bockgård <bojohan@gnu.org>
13852 * xdisp.c (try_cursor_movement): Only check for exact match if
13853 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
13855 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13857 Remove unused external symbols.
13858 * dispextern.h (calc_pixel_width_or_height): Remove decl.
13859 * xdisp.c (calc_pixel_width_or_height): Now static.
13860 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
13861 * indent.c (check_display_width):
13862 * w32term.c: Fix comment to match code.
13863 * xterm.c, xterm.h (x_catching_errors): Remove.
13865 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
13867 * xselect.c: Use signed conversions more consistently (Bug#9498).
13868 (selection_data_to_lisp_data): Assume incoming selection data are
13869 signed integers, not unsigned. This is to be consistent with
13870 outgoing selection data, which was modified to use signed integers
13871 in as part of the fix to Bug#9196 in response to Jan D.'s comment
13872 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
13873 expects long, not unsigned long.
13875 2011-09-14 Eli Zaretskii <eliz@gnu.org>
13877 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
13878 computation of loop end. Reported by Johan Bockgård
13881 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
13883 * frame.c (Fother_visible_frames_p): Function deleted.
13885 2011-09-12 Eli Zaretskii <eliz@gnu.org>
13887 * indent.c (compute_motion): Process display vector front to back
13888 rather than the other way around. (Bug#2496)
13890 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
13892 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
13894 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
13896 * minibuf.c (Fread_from_minibuffer): Doc fix.
13898 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13900 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
13901 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
13903 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
13905 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
13906 value for non-existent files.
13908 2011-09-11 Eli Zaretskii <eliz@gnu.org>
13910 * fileio.c (Finsert_file_contents): If the file cannot be opened,
13911 set its "size" to -1. This will set the modtime_size field of
13912 the corresponding buffer to -1, which is what
13913 verify-visited-file-modtime expects for files that do not exist.
13916 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
13918 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
13920 * lisp.h: ... from here. push_key_description is no longer
13921 defined in keyboard.c, so its declaration should not be in
13922 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
13923 logically belongs with push_key_description.
13925 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
13927 * buffer.h: Include <sys/types.h> instead of <time.h>.
13928 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
13929 Problem reported by Herbert J. Skuhra.
13931 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
13933 * xml.c (parse_region): Make the parsing work for
13934 non-comment-starting XML files again (bug#9144).
13936 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
13938 * image.c (gif_load): Fix calculation of bottom and right corner.
13941 2011-09-10 Eli Zaretskii <eliz@gnu.org>
13943 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
13944 redisplay in small windows.
13946 2011-09-09 Eli Zaretskii <eliz@gnu.org>
13948 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
13950 2011-09-08 Martin Rudalics <rudalics@gmx.at>
13952 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
13953 Operate on live windows only.
13955 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
13957 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
13959 2011-09-07 Eli Zaretskii <eliz@gnu.org>
13961 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
13962 only under bidi iteration.
13964 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
13966 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
13968 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13970 isnan: Fix porting problem to Solaris 10 with bundled gcc.
13971 Without this fix, the command to link temacs failed due to an
13972 undefined symbol __builtin_isnan. This is because
13973 /usr/include/iso/math_c99.h #defines isnan(x) to
13974 __builtin_isnan(x), but the bundled gcc, which identifies itself
13975 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
13977 * floatfns.c (isnan): #undef, and then #define to a clone of
13979 (Fisnan): Always define, since it's always available now.
13980 (syms_of_floatfns): Always define isnan at the Lisp level.
13982 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13984 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
13986 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
13988 * fileio.c: Fix bugs with large file offsets (Bug#9428).
13989 The previous code assumed that file offsets (off_t values) fit in
13990 EMACS_INT variables, which is not true on typical 32-bit hosts.
13991 The code messed up by falsely reporting buffer overflow in cases
13992 such as (insert-file-contents "big" nil 1 2) into an empty buffer
13993 when "big" contains more than 2**29 bytes, even though this
13994 inserts just one byte and does not overflow the buffer.
13995 (Finsert_file_contents): Store file offsets as off_t
13996 values, not as EMACS_INT values. Check for overflow when
13997 converting between EMACS_INT and off_t. When checking for
13998 buffer overflow or for overlap, take the offsets into account.
13999 Don't use EMACS_INT for small values where int suffices.
14000 When checking for overlap, fix a typo: ZV was used where
14001 ZV_BYTE was intended.
14002 (Fwrite_region): Don't assume off_t fits into 'long'.
14003 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
14005 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
14007 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
14009 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14011 sprintf-related integer and memory overflow issues (Bug#9412).
14013 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
14014 (esprintf, exprintf, evxprintf): New functions.
14015 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
14016 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
14017 (modify_event_symbol): Do not assume that the length of
14018 name_alist_or_stem is safe to alloca and fits in int.
14019 (Fexecute_extended_command): Likewise for function name and binding.
14020 (Frecursion_depth): Wrap around reliably on integer overflow.
14021 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
14022 since some callers pass EMACS_INT values.
14023 (Fsingle_key_description): Don't crash if symbol name contains more
14024 than MAX_ALLOCA bytes.
14025 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
14026 (get_minibuffer): Arg is now EMACS_INT, not int.
14027 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
14028 (esprintf, exprintf, evxprintf): New decls.
14029 * window.h (command_loop_level, minibuf_level): Reflect API changes.
14031 * dbusbind.c (signature_cat): New function.
14032 (xd_signature, Fdbus_register_signal):
14033 Do not overrun buffer; instead, report string overflow.
14035 * dispnew.c (add_window_display_history): Don't overrun buffer.
14036 Truncate instead; this is OK since it's just a log.
14038 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
14039 even if the time zone offset is outlandishly large.
14040 Don't mishandle offset == INT_MIN.
14042 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
14043 when creating daemon; the previous buffer-overflow check was incorrect.
14045 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
14046 which has the guts of the old verror function.
14048 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
14049 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
14051 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
14052 (font_unparse_xlfd): Don't blindly alloca long strings.
14053 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
14054 fits in int, when using sprintf. Use single snprintf to count
14055 length of string rather than counting it via multiple sprintfs;
14056 that's simpler and more reliable.
14057 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
14058 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
14059 sprintf, in case result does not fit in int.
14061 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
14062 (fontset_from_font): Print it.
14064 * frame.c (tty_frame_count): Now printmax_t, not int.
14065 (make_terminal_frame, set_term_frame_name): Print it.
14066 (x_report_frame_params): In X, window IDs are unsigned long,
14067 not signed long, so print them as unsigned.
14068 (validate_x_resource_name): Check for implausibly long names,
14069 and don't assume name length fits in 'int'.
14070 (x_get_resource_string): Don't blindly alloca invocation name;
14071 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
14074 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
14075 (xg_check_special_colors, xg_set_geometry):
14076 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
14078 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
14079 Use esprintf, not sprintf, in case result does not fit in int.
14081 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14082 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
14083 it as a large positive number.
14084 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
14085 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
14087 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
14088 in case result does not fit in int.
14090 * print.c (float_to_string): Detect width overflow more reliably.
14091 (print_object): Make sprintf buffer a bit bigger, to avoid potential
14092 buffer overrun. Don't assume list length fits in 'int'. Treat
14093 print length of 0 as 0, not as infinity; to be consistent with other
14094 uses of print length in this function. Don't overflow print length
14095 index. Don't assume hash table size fits in 'long', or that
14096 vectorlike size fits in 'unsigned long'.
14098 * process.c (make_process): Use printmax_t, not int, to format
14099 process-name gensyms.
14101 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
14103 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
14104 to avoid potential buffer overrun.
14106 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
14107 if X resource line is longer than 512 bytes.
14109 * xfns.c (x_window): Make sprintf buffer a bit bigger
14110 to avoid potential buffer overrun.
14112 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
14114 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
14116 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
14118 Integer overflow fixes for scrolling, etc.
14119 Without these, Emacs silently mishandles large integers sometimes.
14120 For example, "C-u 4294967297 M-x recenter" was treated as if
14121 it were "C-u 1 M-x recenter" on a typical 64-bit host.
14123 * xdisp.c (try_window_id): Check Emacs fixnum range before
14124 converting to 'int'.
14126 * window.c (window_scroll_line_based, Frecenter):
14127 Check that an Emacs fixnum is in range before assigning it to 'int'.
14128 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
14129 values converted from Emacs fixnums.
14130 (Frecenter): Don't wrap around a line count if it is out of 'int'
14131 range; instead, treat it as an extreme value.
14132 (Fset_window_configuration, compare_window_configurations):
14133 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
14135 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
14136 that can exceed INT_MAX. Check that EMACS_INT value is in range
14137 before assigning it to the (possibly-narrower) index.
14138 (match_limit): Don't assume that a fixnum can fit in 'int'.
14140 * print.c (print_object): Use ptrdiff_t, not int, for index that can
14143 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
14144 (Fvertical_motion): Don't wrap around LINES values that don't fit
14145 in 'int'. Instead, treat them as extreme values. This is good
14146 enough for windows, which can't have more than INT_MAX lines anyway.
14148 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14150 * Require libxml/parser.h to avoid compilation warning.
14152 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
14154 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
14155 since this reportedly can destroy thread storage.
14157 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
14159 * syntax.c (find_defun_start): Update all cache variables if
14160 exiting early (Bug#9401).
14162 2011-08-30 Eli Zaretskii <eliz@gnu.org>
14164 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
14166 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
14167 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
14168 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
14170 * term.c (tty_append_glyph): New function.
14171 (produce_stretch_glyph): Static function and its prototype deleted.
14173 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
14176 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
14178 * image.c (parse_image_spec): Check for nonnegative, not for positive,
14179 when checking :margin (Bug#9390).
14180 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
14181 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
14182 so that the name doesn't mislead. All uses changed.
14184 2011-08-28 Johan Bockgård <bojohan@gnu.org>
14186 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
14189 2011-08-27 Eli Zaretskii <eliz@gnu.org>
14191 * xdisp.c (move_it_to): Don't bail out early when reaching
14192 position beyond to_charpos, if we are scanning backwards.
14193 (move_it_vertically_backward): When DY == 0, make sure we get to
14194 the first character in the line after the newline.
14196 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
14198 * ccl.c: Improve and simplify overflow checking (Bug#9196).
14199 (ccl_driver): Do not generate an out-of-range pointer.
14200 (Fccl_execute_on_string): Remove unnecessary check for
14201 integer overflow, noted by Stefan Monnier in
14202 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
14203 Remove a FIXME that didn't need fixing.
14204 Simplify the newly-introduced buffer reallocation code.
14206 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
14208 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
14210 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
14212 Integer and memory overflow issues (Bug#9196).
14214 * doc.c (get_doc_string): Rework so that
14215 get_doc_string_buffer_size is the actual buffer size, rather than
14216 being 1 less than the actual buffer size; this makes xpalloc more
14219 * image.c (x_allocate_bitmap_record, cache_image):
14220 * xselect.c (Fx_register_dnd_atom):
14221 Simplify previous changes by using xpalloc.
14223 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
14224 since either will do and ptrdiff_t is convenient with xpalloc.
14226 * charset.c (charset_table_size)
14227 (struct charset_sort_data.priority): Now ptrdiff_t.
14228 (charset_compare): Don't overflow if priorities differ greatly.
14229 (Fsort_charsets): Don't assume list length fits in int.
14230 Check for size-calculation overflow when allocating sort data.
14231 (syms_of_charset): Allocate an initial charset table that is
14232 just under 64 KiB, to avoid problems with glibc malloc and mmap.
14234 * cmds.c (internal_self_insert): Check for size-calculation overflow.
14236 * composite.h (struct composition.glyph_len): Now int, not unsigned.
14237 The actual value is always <= INT_MAX, and leaving it unsigned made
14238 overflow checking harder.
14240 * dispextern.h (struct glyph_matrix.rows_allocated)
14241 (struct face_cache.size): Now ptrdiff_t, for convenience in use
14242 with xpalloc. The values are still always <= INT_MAX.
14244 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
14246 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
14247 (SAFE_NALLOCA): New macro.
14249 * region-cache.c (struct boundary.pos, find_cache_boundary)
14250 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
14251 (set_cache_region, invalidate_region_cache)
14252 (revalidate_region_cache, know_region_cache, region_cache_forward)
14253 (region_cache_backward, pp_cache):
14254 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
14255 so that ptrdiff_t * can be passed to xpalloc.
14256 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
14257 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
14258 (pp_cache): Don't assume cache_len fits in int.
14259 * region-cache.h: Adjust extern decls to match.
14261 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
14262 EMACS_INT, since either will do, for xpalloc.
14264 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
14265 (xnmalloc, xnrealloc, xpalloc): New functions.
14267 * bidi.c (bidi_shelve_header_size): New constant.
14268 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
14269 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
14271 * bidi.c (bidi_cache_shrink):
14272 * buffer.c (overlays_at, overlays_in, record_overlay_string)
14274 Don't update size of array until after memory allocation succeeds,
14275 because xmalloc/xrealloc may not return.
14276 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
14277 now that we have proper integer overflow checking.
14278 (record_overlay_string, overlay_strings): Catch overflows when
14279 calculating size of overlay_str_buf.
14281 * callproc.c (Fcall_process): Check for size overflow when
14282 calculating size of args2.
14283 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
14284 Normally we prefer signed values, but sticking with ptrdiff_t would
14285 require adding more-complicated checks.
14287 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
14288 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
14289 Redo buffer-overflow calculations to avoid integer overflow.
14290 Add a FIXME comment where memory seems to be over-allocated.
14292 * character.c (Fstring): Check for size-calculation overflow.
14294 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
14295 unnecessary integer overflow. Check for size overflow.
14296 (encode_coding_object): Don't update size until xmalloc succeeds.
14298 * composite.c (get_composition_id): Check for overflow in glyph
14299 length calculations.
14301 Integer and memory overflow fixes for display code.
14302 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
14303 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
14304 (scrolling_window): Check for overflow in size calculations.
14305 (line_draw_cost, realloc_glyph_pool, add_row_entry):

14328 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
14330 * emacs.c (main): Do not reallocate argv, since there is a null at
14331 the end that can be overwritten, and this way there's no need to
14332 worry about size-calculation overflow.

14462 (X_LONG_MIN): New macros.
14463 Use them to make the following changes clearer.
14464 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

14466 future maintainers not to raise the value too much later.
14467 (SELECTION_QUANTUM): Remove, replacing with ...
14468 (selection_quantum): ... new function, which avoids overflow.
14470 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
14471 assumption that selection length fits in 'int'.

14488 Don't store size until memory allocation succeeds.
14489 (x_get_window_property): Plug memory leak on memory exhaustion.
14490 Don't double-block input; malloc is safe here. Don't assume 2**34
14491 - 4 fits in unsigned long. Add an xassert to check
14492 XGetWindowProperty overflow. Be more careful about overflow
14493 calculations, and distinguish size from memory overflow better.

14500 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
14501 result parameters unless successful. Rely on cons_to_unsigned
14502 to report problems with elements; the old code wasn't right anyway.

14537 * lisp.h (hash_lookup, hash_put):
14538 * minibuf.c (Ftest_completion):
14539 Use ptrdiff_t for hash table indexes, not int (which is too
14540 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
14541 32-bit --with-wide-int hosts).
14543 * charset.c (Fdefine_charset_internal): Check for integer overflow.
14544 Add a FIXME comment about memory leaks.

14573 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
14574 (x_send_scroll_bar_event): Likewise. Check that the size does not
14575 exceed limits imposed by XClientMessageEvent, as well as the usual
14576 ptrdiff_t and size_t limits.
14578 * keyboard.c: Overflow, signedness and related fixes.
14579 (make_lispy_movement): Use same integer type in forward decl
14580 that is used in the definition.

14582 Change bufsize argument back to int, undoing my 2011-03-30 change.
14583 We prefer signed types, and int is wide enough here.
14584 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
14585 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
14586 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
14587 length, not size_t. Use ptrdiff_t for index, not int.
14588 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
14589 possibility of integer overflow.

14617 Prefer int to unsigned where either will do.
14618 (tiff_handler): New function, combining the cores of the
14619 old tiff_error_handler and tiff_warning_handler.

14621 stack buffer overflows. It uses only the features of vsnprintf
14622 that are common to both POSIX and native Microsoft.
14623 (tiff_error_handler, tiff_warning_handler): Use it.
14624 (tiff_load, gif_load, imagemagick_load_image):
14625 Don't assume :index value fits in 'int'.

14628 the integer types that MagickCropImage accepts. Don't assume
14629 Vimagemagick_render_type has a nonnegative value. Don't assume

14668 buffers, return left-to-right.
14669 (set_cursor_from_row): Consider candidate row a win if its glyph

14671 positioning on the newline at EOL of R2L text within L2R
14672 paragraph, and vice versa.
14673 (try_cursor_movement): Check continued rows, in addition to
14674 continuation rows. Fixes unwarranted scroll when point enters a
14675 continued line of R2L text within an L2R paragraph, or vice versa.
14676 (cursor_row_p): Consider the case of point being equal to
14677 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
14678 from the end of a short line to the beginning of a continued line
14679 of R2L text within L2R paragraph.

14706 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
14707 instead of CHAR_TO_BYTE. Fixes a crash when a completion
14708 candidate is selected by the mouse, and that candidate has a
14709 composed character under the mouse.
14711 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
14712 coordinates reported by pos-visible-in-window-p for a composed

14722 consider it a hit if to_charpos is anywhere in the range of the
14723 composed buffer positions.
14725 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
14727 * image.c (gif_load): Don't assume that each subimage has the same
14728 dimensions as the base image. Handle disposal method that is
14729 "undefined" by the gif spec (Bug#9335).
14731 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
14733 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

14736 2011-08-19 Eli Zaretskii <eliz@gnu.org>
14738 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
14739 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
14740 from an Org mode buffer to a Speedbar frame.
14742 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
14743 a composition, take its buffer position from IT->cmp_it.charpos.
14744 Fixes cursor positioning at the beginning of a line that begins
14745 with a composed character.
14747 2011-08-18 Eli Zaretskii <eliz@gnu.org>
14749 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
14750 character bidirectional type, use STRONG_L instead. Fixes crashes
14751 in a buffer produced by `describe-categories'.
14753 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
14754 members before the level stack, so they would be saved and
14755 restored when copying iterator state. Fixes incorrect reordering
14756 around TABs covered by display properties.
14758 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
14760 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
14762 2011-08-17 Chong Yidong <cyd@stupidchicken.com>

14765 (internal_condition_case_2, internal_condition_case_n):
14766 Remove unnecessary aborts (Bug#9081).
14768 2011-08-17 Eli Zaretskii <eliz@gnu.org>
14770 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
14771 has no `load' handler, try opening the file locally. (Bug#9311)
14773 2011-08-16 Ken Brown <kbrown@cornell.edu>
14775 * gmalloc.c: Expand comment.
14777 2011-08-16 Eli Zaretskii <eliz@gnu.org>

14791 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
14793 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
14794 in the static heap.
14795 [CYGWIN] (special_realloc): New function.
14796 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
14797 requests to realloc storage in the static heap.

14812 * chartab.c: Improve commentary for the uniprop_table API.
14814 * bidi.c (bidi_paragraph_init): Support zero value of
14815 bidi_ignore_explicit_marks_for_paragraph_level.
14816 (bidi_initialize): Use uniprop_table instead of including
14817 biditype.h and bidimirror.h.
14819 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
14820 coordinates of the iterator when restoring from ppos_it.
14823 2011-08-14 Kenichi Handa <handa@m17n.org>

14828 2011-08-14 Eli Zaretskii <eliz@gnu.org>
14830 * xdisp.c (move_it_in_display_line_to): Don't invoke
14831 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
14832 ppos_it. Fixes vertical cursor motion when line beginning is
14833 covered by an image. (Bug#9296)
14835 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
14837 * nsterm.h (ns_run_ascript): Declare.
14838 (NSAPP_DATA2_RUNASSCRIPT): Define.
14840 * nsfns.m (as_script, as_result, as_status): New static variables.
14841 (ns_run_ascript): New function.
14842 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
14843 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
14844 the event loop. Get status from as_status (Bug#7276).
14846 * nsterm.m (sendEvent): If event is NSApplicationDefined and
14847 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
14848 the event loop (Bug#7276).
14850 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
14852 * gnutls.c (QCgnutls_bootprop_priority)
14853 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
14854 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
14855 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
14856 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
14857 (QCgnutls_bootprop_verify_hostname_error)
14858 (QCgnutls_bootprop_callbacks_verify): Rename from
14859 Qgnutls_bootprop_..., all uses changed.
14861 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
14864 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
14866 * xfaces.c (Qframe_set_background_mode): Now static.

14871 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
14873 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
14874 (Fnetwork_interface_list): Allocate in increments of bytes instead
14875 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
14876 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
14878 (struct ifflag_def): notrailers is smart on OSX.
14879 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
14880 Get hardware address with getifaddrs if available.
14882 2011-08-12 Eli Zaretskii <eliz@gnu.org>
14884 * xdisp.c (iterate_out_of_display_property): xassert that
14885 IT->position is set to within IT->object's boundaries. Break from
14886 the loop as soon as EOB is reached; avoids infloops in redisplay
14887 when IT->position is set up wrongly due to some bug.
14888 Set IT->current to match the bidi iterator unconditionally.
14889 (push_display_prop): Allow GET_FROM_STRING as IT->method on
14890 entry. Force push_it to save on the stack the current
14891 buffer/string position, to be restored by pop_it. Fix flags in
14892 the iterator structure wrt the object coming from a display
14893 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
14894 properties. (Bug#9284)
14896 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
14898 * fontset.c (fontset_get_font_group): Add proper type checks.

14911 no-display-properties-and-no-overlays under bidi display.
14912 Set disp_pos in the bidi iterator to avoid searches for display
14913 properties and overlays.
14915 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
14917 * editfns.c (Fset_time_zone_rule): Document relationship with the

14921 the font entity extracted from the cache (Bug#8109).
14923 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
14925 * composite.c (autocmp_chars): Don't reset point. That is done by
14926 restore_point_unwind (Bug#5984).
14928 2011-08-07 Juri Linkov <juri@jurta.org>
14930 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
14931 to show the arg `TIME' instead of `TIMEVAL'.
14933 2011-08-06 Eli Zaretskii <eliz@gnu.org>
14935 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
14936 display property strides EOL and includes a newline, as in
14937 longlines-mode. (Bug#9254)
14938 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
14939 word-wrap under bidirectional display. (Bug#9224)
14941 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
14942 is non-zero, even if the data buffer is NULL. Fixes a crash in
14943 vertical-motion with longlines-mode. (Bug#9254)
14945 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14947 * bidi.c <bidi_cache_total_alloc>: Now static.
14948 (bidi_initialize): Initialize bidi_cache_total_alloc.
14950 * xdisp.c (display_line): Release buffer allocated for shelved bidi
14953 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
14954 amount allocated this far in `bidi_cache_total_alloc'.
14955 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
14956 non-zero, only free the data buffer without restoring the cache
14957 contents. All callers changed.
14959 * dispextern.h (bidi_unshelve_cache): Update prototype.
14961 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
14962 (move_it_in_display_line, move_it_to)
14963 (move_it_vertically_backward, move_it_by_lines): Replace the call
14964 to xfree to an equivalent call to bidi_unshelve_cache.
14965 (move_it_in_display_line_to): Fix logic of returning
14966 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
14968 2011-08-05 Eli Zaretskii <eliz@gnu.org>
14970 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
14971 came from a string character with a `cursor' property. (Bug#9229)
14973 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14975 * Makefile.in (LIB_PTHREAD): New variable.
14976 (LIBES): Add LIB_PTHREAD (Bug#9216).
14978 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
14979 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
14981 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
14983 * regex.c (re_iswctype): Remove some redundant boolean conversions.
14985 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
14987 * xterm.c (x_find_topmost_parent): New function.
14988 (x_set_frame_alpha): Find topmost parent window with
14989 x_find_topmost_parent and set the property there also (bug#9181).
14990 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
14992 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
14994 * callproc.c (Fcall_process): Avoid vfork clobbering
14995 the local vars buffer, coding_systems, current_dir.
14997 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
14999 * keymap.c (Fmake_composed_keymap): Move to subr.el.
15001 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
15003 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
15004 so that it is not optimized away.
15006 * xdisp.c (compute_display_string_pos): Remove unused local.
15008 2011-08-02 Eli Zaretskii <eliz@gnu.org>
15010 Fix slow cursor motion and scrolling in large buffers with
15011 selective display, like Org Mode buffers. (Bug#9218)
15013 * dispextern.h (struct bidi_it): New member disp_prop_p.
15015 * xdisp.c: Remove one-slot cache of display string positions.
15016 (compute_display_string_pos): Accept an additional argument
15017 DISP_PROP_P; callers changed. Scan at most 5K characters forward
15018 for a display string or property. If found, set DISP_PROP_P
15021 * bidi.c (bidi_fetch_char): Accept an additional argument
15022 DISP_PROP_P, and pass it to compute_display_string_pos.
15023 Only handle text covered by a display string if DISP_PROP_P is returned
15024 non-zero. All callers of bidi_fetch_char changed.
15026 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
15028 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
15030 2010-12-03 Don March <don@ohspite.net>
15032 * keymap.c (Fdefine_key): Fix non-prefix key error message when
15033 last character M-[char] is translated to ESC [char] (bug#7541).
15035 2011-08-02 Kenichi Handa <handa@m17n.org>
15037 * lisp.h (uniprop_table): Extern it.
15039 * chartab.c (uniprop_table): Make it non-static.
15041 2011-08-01 Eli Zaretskii <eliz@gnu.org>
15043 * xdisp.c (forward_to_next_line_start): Accept additional argument
15044 BIDI_IT_PREV, and store into it the state of the bidi iterator had
15046 (reseat_at_next_visible_line_start): Use the bidi iterator state
15047 returned by forward_to_next_line_start to restore the state of
15048 it->bidi_it after backing up to previous newline. (Bug#9212)
15050 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
15052 * regex.c (re_comp): Protoize.
15053 (re_exec): Fix return type.
15054 (regexec): Fix type of `ret'. (Bug#9203)
15056 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15058 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
15059 This is needed if max-image-size is a floating-point number.
15061 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15063 * print.c (print_object): Print empty symbol as ##.
15065 * lread.c (read1): Read ## as empty symbol.
15067 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15069 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
15070 setting frame foreground color (Bug#9175).
15071 (x_set_background_color): Likewise.
15073 * nsmenu.m (-setText): Size tooltip dimensions precisely to
15074 contents (Bug#9176).
15075 (EmacsTooltip -init): Remove bezels and add shadows to
15078 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
15079 or scroll bar (Bug#8470).
15081 * nsfont.m (nsfont_open): Remove assignment to voffset and
15082 unnecessary vars hshink, expand, hd, full_height, min_height.
15083 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
15085 * nsterm.h (nsfont_info): Remove voffset field.
15087 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
15089 Implement strike-through and overline on NextStep (Bug#8863).
15091 * nsfont.m (nsfont_open): Use underline position provided by font,
15092 instead of hard-coded value of 2.
15093 (nsfont_draw): Call ns_draw_text_decoration instead.
15095 * nsterm.h: Add declaration for ns_draw_text_decoration.
15097 * nsterm.m (ns_draw_text_decoration): New function for drawing
15098 underline, overline, and strike-through.
15099 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
15100 ns_draw_text_decoration. Change treatment of cursor drawing to
15101 accommodate underlining, etc.
15103 2011-07-28 Eli Zaretskii <eliz@gnu.org>
15105 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
15108 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15110 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
15111 Without this fix, if a signal arrives just after memory fills up,
15112 'malloc' might be invoked reentrantly.
15114 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
15115 In other words, assume that every image size is allowed, on non-X
15116 hosts. This assumption is probably wrong, but it lets Emacs compile.
15118 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
15120 * regex.c (re_iswctype): Convert return values to boolean.
15122 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
15124 * xdisp.c (compute_display_string_pos): Don't use cached display
15125 string position if the buffer had its restriction changed.
15128 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15130 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
15132 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
15134 Integer signedness and overflow and related fixes. (Bug#9079)
15136 * bidi.c: Integer size and overflow fixes.
15137 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
15138 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
15139 (bidi_cache_find_level_change, bidi_cache_ensure_space)
15140 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
15141 (bidi_find_other_level_edge):
15142 Use ptrdiff_t instead of EMACS_INT where either will do.
15143 This works better on 32-bit hosts configured --with-wide-int.
15144 (bidi_cache_ensure_space): Check for size-calculation overflow.
15145 Use % rather than repeated addition, for better worst-case speed.
15146 Don't set bidi_cache_size until after xrealloc returns, because it
15148 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
15149 (bidi_cache_ensure_space): Also check that the bidi cache size
15150 does not exceed that of the largest Lisp string or buffer. See Eli
15151 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
15153 * alloc.c (__malloc_size_t): Remove.
15154 All uses replaced by size_t. See Andreas Schwab's note
15155 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
15157 * image.c: Improve checking for integer overflow.
15158 (check_image_size): Assume that f is nonnull, since
15159 it is always nonnull in practice. This is one less thing to
15160 worry about when checking for integer overflow later.
15161 (x_check_image_size): New function, which checks for integer
15162 overflow issues inside X.
15163 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
15164 This removes the need for a memory_full check.
15165 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
15166 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
15167 (xbm_read_bitmap_data): Change locals back to 'int', since
15168 their values must fit in 'int'.
15169 (xpm_load_image, png_load, tiff_load):
15170 Invoke x_create_x_image_and_pixmap earlier,
15171 to avoid much needless work if the image is too large.
15172 (tiff_load): Treat overly large images as if
15173 x_create_x_image_and_pixmap failed, not as malloc failures.
15174 (gs_load): Use x_check_image_size.
15176 * gtkutil.c: Omit integer casts.
15177 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
15178 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
15180 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
15182 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
15183 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
15184 would wrongly return t on a 64-bit host.
15186 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
15187 The plain *_OVERFLOW macros run afoul of GCC bug 49705
15188 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
15189 and therefore cause GCC to emit a bogus diagnostic in some cases.
15191 * image.c: Integer signedness and overflow and related fixes.
15192 This is not an exhaustive set of fixes, but it's time to
15193 record what I've got.
15194 (lookup_pixel_color, check_image_size): Remove redundant decls.
15195 (check_image_size): Don't assume that arbitrary EMACS_INT values
15196 fit in 'int', or that arbitrary 'double' values fit in 'int'.
15197 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
15198 (tiff_load, imagemagick_load_image):
15199 Check for overflow in size calculations.
15200 (x_create_x_image_and_pixmap): Remove unnecessary test for
15201 xmalloc returning NULL; that can't happen.
15202 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
15203 (xpm_color_bucket): Use better integer hashing function.
15204 (xpm_cache_color): Don't possibly over-allocate memory.
15205 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
15206 (gif_memory_source):
15207 Use ptrdiff_t, not int or size_t, to record sizes.
15208 (png_load): Don't assume values greater than 2**31 fit in 'int'.
15209 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
15210 either works, as we prefer signed integers.
15211 (tiff_read_from_memory, tiff_write_from_memory):
15212 Return tsize_t, not size_t, since that's what the TIFF API wants.
15213 (tiff_read_from_memory): Don't fail simply because the read would
15214 go past EOF; instead, return a short read.
15215 (tiff_load): Omit no-longer-needed casts.
15216 (Fimagemagick_types): Don't assume size fits into 'int'.
15218 Improve hashing quality when configured --with-wide-int.
15219 * fns.c (hash_string): New function, taken from sxhash_string.
15220 Do not discard information about ASCII character case; this
15221 discarding is no longer needed.
15222 (sxhash-string): Use it. Change sig to match it. Caller changed.
15223 * lisp.h: Declare it.
15224 * lread.c (hash_string): Remove, since we now use fns.c's version.
15225 The fns.c version returns a wider integer if --with-wide-int is
15226 specified, so this should help the quality of the hashing a bit.
15228 * emacs.c: Integer overflow minor fix.
15229 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
15230 Define only if GNU_LINUX.
15231 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
15233 * dispnew.c: Integer signedness and overflow fixes.
15234 Remove unnecessary forward decls, that were a maintenance hassle.
15235 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
15237 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
15238 (scrolling_window): Use ptrdiff_t, not int, for byte count.
15239 (prepare_desired_row, line_draw_cost):
15240 Use int, not unsigned, where either works.
15241 (save_current_matrix, restore_current_matrix):
15242 Use ptrdiff_t, not size_t, where either works.
15243 (init_display): Check for overflow more accurately, and without
15244 relying on undefined behavior.
15246 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
15247 Remove, replacing with the new symbols in lisp.h. All uses changed.
15248 * fileio.c (make_temp_name):
15249 * filelock.c (lock_file_1, lock_file):
15250 * xdisp.c (message_dolog):
15251 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
15252 Use pMd etc. instead.
15253 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
15254 replacing the pWIDE etc. symbols removed from editfns.c.
15256 * keyboard.h (num_input_events): Now uintmax_t.
15257 This is (very slightly) less likely to mess up due to wraparound.
15260 * buffer.c: Integer signedness fixes.
15261 (alloc_buffer_text, enlarge_buffer_text):
15262 Use ptrdiff_t rather than size_t when either will do, as we prefer
15265 * alloc.c: Integer signedness and overflow fixes.
15266 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
15267 (__malloc_size_t): Default to size_t, not to int.
15268 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
15269 (Fgarbage_collect, mark_object_loop_halt, mark_object):
15270 Prefer ptrdiff_t to size_t when either would do, as we prefer
15272 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
15273 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
15274 Now const. Initialize with values that are in range even if char
15276 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
15277 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
15278 These functions do the right thing with sizes > 2**32.
15279 (check_depth): Now ptrdiff_t, not int.
15280 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
15281 Adjust to new way of storing sizes. Check for size overflow bugs
15283 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
15284 slightly wrong anyway, as it missed one instance of
15285 XMALLOC_OVERRUN_CHECK_OVERHEAD.
15286 (refill_memory_reserve): Omit needless cast to size_t.
15287 (mark_object_loop_halt): Mark as externally visible.
15289 * xselect.c: Integer signedness and overflow fixes.
15290 (Fx_register_dnd_atom, x_handle_dnd_message):
15291 Use ptrdiff_t, not size_t, since we prefer signed.
15292 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
15293 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
15294 x_dnd_atoms_size and x_dnd_atoms_length.
15296 * doprnt.c: Prefer signed to unsigned when either works.
15298 * doprnt.c (doprnt):
15300 * xdisp.c (vmessage):
15301 Use ptrdiff_t, not size_t, when using or implementing doprnt,
15302 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
15303 prefer signed arithmetic to avoid comparison confusion.
15304 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
15305 but is a bit tricky.
15307 Assume freestanding C89 headers, string.h, stdlib.h.
15308 * data.c, doprnt.c, floatfns.c, print.c:
15309 Include float.h unconditionally.
15310 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
15311 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
15312 * regex.c: Likewise for stddef.h, string.h.
15313 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
15314 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
15315 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
15316 (STDC_HEADERS): Remove obsolete defines.
15317 * sysdep.c: Include limits.h unconditionally.
15319 Assume support for memcmp, memcpy, memmove, memset.
15320 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
15321 * regex.c (memcmp, memcpy):
15322 Remove; we assume C89 now.
15324 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
15325 (__malloc_safe_bcopy): Remove; no longer needed.
15327 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
15328 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
15329 well either way, and we prefer signed to unsigned.
15331 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
15333 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
15334 closes the connection while we're reading (bug#9182).
15336 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
15338 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
15339 are specified (Bug#9168).
15341 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
15343 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
15344 Found by GCC static checking and --with-wide-int on a 32-bit host.
15346 2011-07-25 Eli Zaretskii <eliz@gnu.org>
15348 * xdisp.c (compute_display_string_pos): Fix logic of caching
15349 previous display string position. Initialize cached_prev_pos to
15350 -1. Fixes slow-down at the beginning of a buffer.
15352 2011-07-24 Eli Zaretskii <eliz@gnu.org>
15354 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
15355 for attrs[LFACE_FONTSET_INDEX].
15357 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
15359 * xml.c (parse_region): Remove unused local
15360 that was recently introduced.
15362 2011-07-23 Eli Zaretskii <eliz@gnu.org>
15364 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
15365 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
15367 * xdisp.c (move_it_in_display_line_to): Record the best matching
15368 position for TO_CHARPOS while scanning the line, and restore it on
15369 exit if none of the characters scanned was an exact match.
15370 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
15371 when exact match is impossible due to invisible text, and the
15372 lines are truncated.
15374 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
15376 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
15379 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15381 Fix a significant slow-down of cursor motion with C-n, C-p,
15382 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
15383 auto-repeat under bidi redisplay in fontified buffers.
15384 * xdisp.c (compute_stop_pos_backwards): New function.
15385 (next_element_from_buffer): Call compute_stop_pos_backwards to
15386 find a suitable prev_stop when we find ourselves before
15388 (reseat): Don't look for prev_stop, as that could mean a very long
15390 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
15391 <cached_disp_overlay_modiff>: Cache for last found display string
15393 (compute_display_string_pos): Return the cached position if asked
15394 about the same buffer in the same area of character positions, and
15395 the buffer wasn't changed since the time the display string
15396 position was cached.
15398 2011-07-22 Eli Zaretskii <eliz@gnu.org>
15400 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
15401 is an integer, which is important for empty lines. (Bug#9149)
15403 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
15405 * frame.c (Fmodify_frame_parameters): In tty case, update the
15406 default face if necessary (Bug#4238).
15408 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
15410 * editfns.c (Fstring_to_char): No need to explain what a character
15411 is in the docstring (Bug#6576).
15413 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15415 * xml.c (parse_region): Make sure we always return a tree.
15417 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
15419 * xml.c (parse_region): If a document contains only comments,
15422 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
15424 * xml.c (make_dom): Return comments, too.
15426 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
15429 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
15430 and the surrounding thread.
15431 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
15432 rather than fgets, and retry after EINTR. Otherwise, 'emacs
15433 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
15435 * s/openbsd.h (BROKEN_SIGIO): Define.
15436 * unexelf.c (unexec) [__OpenBSD__]:
15437 Don't update the .mdebug section of the Alpha COFF symbol table.
15439 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15441 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
15444 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
15446 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
15447 This fixes some race conditions on the permissions of any newly
15450 * alloc.c (valid_pointer_p): Use pipe, not open.
15451 This fixes some permissions issues when debugging.
15453 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
15454 If fchown fails to set both uid and gid, try to set just gid,
15455 as that is sometimes allowed. Adjust the file's mode to eliminate
15456 setuid or setgid bits that are inappropriate if fchown fails.
15458 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
15460 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
15461 to compare Lisp_Objects.
15462 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
15463 global_gnutls_log_level, don't mistake it for a Lisp_Object.
15464 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
15466 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
15468 * lread.c (read_integer): Unread even EOF character.
15469 (read1): Likewise. Properly record start position of symbol.
15471 * lread.c (read1): Read `#:' as empty uninterned symbol if no
15472 symbol character follows.
15474 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
15476 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
15477 This works around a problem with the previous change to Fcopy_file.
15478 Recent glibc declares fchown with __attribute__((warn_unused_result)),
15479 and without this change, GCC might complain about discarding
15480 fchown's return value.
15482 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
15484 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
15486 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
15488 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
15490 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
15492 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
15493 it's used from the C level.
15495 * process.c: Use the same condition for POLL_FOR_INPUT in both
15496 keyboard.c and process.c (bug#1858).
15498 2011-07-09 Lawrence Mitchell <wence@gmx.li>
15500 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
15501 (Fgnutls_boot): Use it.
15503 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
15505 * doc.c (Fsubstitute_command_keys): Revert last change.
15507 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
15509 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
15510 quotes the next character, and doesn't affect other longer
15511 sequences (bug#8935).
15513 * lread.c (syms_of_lread): Clarify that is isn't only
15514 `eval-buffer' and `eval-defun' that's affected by
15515 `lexical-binding' (bug#8460).
15517 2011-07-15 Eli Zaretskii <eliz@gnu.org>
15519 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
15520 bidi redisplay when a line includes both an image and is truncated.
15522 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
15524 Fix minor problems found by static checking.
15525 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
15526 (elsz): Now a signed constant, not a size_t var. We prefer signed
15527 types to unsigned, to avoid integer comparison confusion. Without
15528 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
15529 "cannot optimize loop, the loop counter may overflow", a symptom
15531 * indent.c (Fvertical_motion): Mark locals as initialized.
15532 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
15534 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
15536 * search.c (Fre_search_backward): Mention `case-fold-search' in
15537 all the re_search_* functions (bug#8138).
15539 * keyboard.c (Fopen_dribble_file): Document when the file is
15542 2011-07-14 Eli Zaretskii <eliz@gnu.org>
15544 * bidi.c (bidi_dump_cached_states): Fix format of displaying
15547 Support bidi reordering of display and overlay strings.

15549 (compute_display_string_end): Accept additional argument STRING.
15550 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
15551 (reseat_to_string): Initialize bidi_it->string.s and
15552 bidi_it->string.schars.
15553 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
15554 NULL (avoids a crash in bidi_paragraph_init).
15555 Initialize itb.string.lstring.
15556 (init_iterator): Call bidi_init_it only of a valid
15557 buffer position was specified. Initialize paragraph_embedding to
15559 (reseat_to_string): Initialize the bidi iterator.
15560 (display_string): If we need to ignore text properties of
15561 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
15562 original value of -1 will not work with bidi.)
15563 (compute_display_string_pos): First arg is now struct
15564 `text_pos *'; all callers changed. Support display properties on
15566 (compute_display_string_end): Support display properties on Lisp
15568 (init_iterator, reseat_1, reseat_to_string): Initialize the
15569 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
15570 when iterating on a string not from display properties).
15571 (compute_display_string_pos, compute_display_string_end):
15572 Fix calculation of the object to scan. Fixes an error when using
15574 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
15575 base_level_stop; instead, set base_level_stop to BEGV.
15576 Fixes crashes in vertical-motion.
15577 (next_element_from_buffer): Improve commentary for when
15578 the iterator is before prev_stop.
15579 (init_iterator): Initialize bidi_p from the default value of
15580 bidi-display-reordering, not from buffer-local value. Use the
15581 buffer-local value only if initializing for buffer iteration.
15582 (handle_invisible_prop): Support invisible properties on strings
15583 that are being bidi-reordered.
15584 (set_iterator_to_next): Support bidi reordering of C strings and
15586 (next_element_from_string): Support bidi reordering of Lisp
15588 (handle_stop_backwards): Support Lisp strings as well.
15589 (display_string): Support display of R2L glyph rows.
15590 Use IT_STRING_CHARPOS when displaying from a Lisp string.
15591 (init_iterator): Don't initialize it->bidi_p for strings
15593 (reseat_to_string): Initialize it->bidi_p for strings here.
15594 (next_element_from_string, next_element_from_c_string)
15595 (next_element_from_buffer): Add xassert's for correspondence
15596 between IT's object being iterated and it->bidi_it.string
15598 (face_before_or_after_it_pos): Support bidi iteration.
15599 (next_element_from_c_string): Handle the case of the first string
15600 character that is not the first one in the visual order.
15601 (get_visually_first_element): New function, refactored from common
15602 parts of next_element_from_buffer, next_element_from_string, and
15603 next_element_from_c_string.
15604 (tool_bar_lines_needed, redisplay_tool_bar)
15605 (display_menu_bar): Force left-to-right direction. Add a FIXME
15606 comment for making that be controlled by a user option.
15607 (push_it, pop_it): Save and restore the state of the
15608 bidi iterator. Save and restore the bidi_p flag.
15609 (pop_it): Iterate out of display property for string iteration as
15611 (iterate_out_of_display_property): Support iteration over strings.
15612 (handle_single_display_spec): Set up it->bidi_it for iteration
15613 over a display string, and call bidi_init_it.
15614 (handle_single_display_spec, next_overlay_string)
15615 (get_overlay_strings_1, push_display_prop): Set up the bidi
15616 iterator for displaying display or overlay strings.
15617 (forward_to_next_line_start): Don't use the shortcut if
15619 (back_to_previous_visible_line_start): If handle_display_prop
15620 pushed the iterator stack, restore the internal state of the bidi
15621 iterator by calling bidi_pop_it same number of times.
15622 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
15623 and we are bidi-iterating, don't decrement the iterator position;
15624 instead, set the first_elt flag in the bidi iterator, to produce
15626 (reseat_1): Remove redundant setting of string_from_display_prop_p.
15627 (push_display_prop): xassert that we are iterating a buffer.
15628 (push_it, pop_it): Save and restore paragraph_embedding member.
15629 (handle_single_display_spec, next_overlay_string)
15630 (get_overlay_strings_1, reseat_1, reseat_to_string)
15631 (push_display_prop): Set up the `unibyte' member of bidi_it.string
15632 correctly. Don't assume unibyte strings are not bidi-reordered.
15633 (compute_display_string_pos)
15634 (compute_display_string_end): Fix handling the case of C string.
15635 (push_it, pop_it): Save and restore from_disp_prop_p.

16095 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
16097 Random fixes. E.g., (random) never returned negative values.
16098 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
16099 subseconds part to the entropy, as that's a bit more random.
16100 Prefer signed to unsigned, since the signedness doesn't matter and
16101 in general we prefer signed. When given a limit, use a
16102 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
16103 latter isn't right if USE_2_TAGS_FOR_INTS.
16104 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
16105 not 0..VALMASK. Don't discard "excess" bits that random () returns.
16107 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
16109 * textprop.c (text_property_stickiness):
16110 Obey Vtext_property_default_nonsticky.

16118 This is more efficient than Ffile_directory_p and avoids a minor race.
16120 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
16122 * buffer.c (Foverlay_put): Say what the return value is
16125 * fileio.c (barf_or_query_if_file_exists): Check first if the file
16126 is a directory before asking whether to use the file name
16128 (barf_or_query_if_file_exists): Make the "File is a directory"
16129 error be more correct.
16131 * fns.c (Frequire): Remove the mention of the .gz files, since
16132 that's installation-specific, but keep the mention of
16133 `get-load-suffixes'.
16135 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
16137 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

16142 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
16143 (syms_of_gnutls): Remove duplicate DEFSYM for
16144 Qgnutls_bootprop_verify_hostname_error, an error for
16145 Qgnutls_bootprop_verify_error (which is no longer used).
16147 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
16148 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
16149 Also (re)move comments that are misplaced or no longer relevant.
16151 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16153 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

16181 * fns.c (Frequire): Mention .el.gz files (bug#7314).
16182 (Frequire): Mention get-load-suffixes.

16212 (syms_of_keymap): Defsubr make-composed-keymap.
16213 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

16250 * eval.c (struct backtrace): Simplify and port the data structure.
16251 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
16252 signed bit field, as this assumption is not portable and it makes
16253 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
16254 "char debug_on_exit : 1" as this is not portable either; instead,
16255 use the portable "unsigned int debug_on_exit : 1". Remove unused
16256 member evalargs. Remove obsolete comments about cc bombing out.
16258 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
16260 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

16326 (emacs_fixed_new): Set priv->f to argument.
16327 (emacs_fixed_get_preferred_width)
16328 (emacs_fixed_get_preferred_height): Use min_width/height from
16329 frames size_hint to set minimum and natural (Bug#8919).
16330 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
16331 and use min_width/height from frames size_hint to set
16332 min_width/height (Bug#8919).

16424 * print.c (printchar, strout): Check for string overflow.
16425 (PRINTPREPARE, printchar, strout):
16426 Don't set size unless allocation succeeds.
16428 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
16429 for sizes. Check for string overflow more accurately.

16433 * keyboard.h (struct keyboard.kbd_macro_bufsize):
16434 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

16443 (read_integer): Radix is now EMACS_INT, not int,
16444 to improve quality of diagnostics for out-of-range radices.
16445 Calculate buffer size correctly for out-of-range radices.
16446 (read1): Check for integer overflow in radices, and in
16447 read-circle numbers.
16448 (read_escape): Avoid int overflow.
16449 (Fload, openp, read_buffer_size, read1)
16450 (substitute_object_recurse, read_vector, read_list, map_obarray):
16451 Use ptrdiff_t, not int, for sizes.

16471 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
16473 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
16474 The following patches are for when GLYPH_DEBUG && !XASSERT.
16475 * dispextern.h (trace_redisplay_p, dump_glyph_string):
16476 * dispnew.c (flush_stdout):
16477 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
16478 Mark as externally visible.
16479 * dispnew.c (check_window_matrix_pointers): Now static.
16480 * dispnew.c (window_to_frame_vpos):
16481 * xfns.c (unwind_create_frame):

16488 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
16490 (debug_method_add): Use va_list and vsprintf rather than relying
16491 on undefined behavior with wrong number of arguments.
16492 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
16493 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
16494 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
16495 since we're not interested in debugging glyphs with old libraries.
16496 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
16497 GCC 4.6.0's static checking.
16499 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

16517 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
16518 (.bitmaps_last, struct x_output.icon_bitmap):
16519 Use ptrdiff_t, not int, for bitmap indexes.
16520 (x_allocate_bitmap_record): Check for size overflow.
16521 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
16523 Use ptrdiff_t, not int, for overlay counts.
16524 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
16525 * editfns.c (overlays_around, get_pos_property):
16526 * textprop.c (get_char_property_and_overlay):
16527 * xdisp.c (next_overlay_change, note_mouse_highlight):
16528 * xfaces.c (face_at_buffer_position):
16529 * buffer.c (OVERLAY_COUNT_MAX): New macro.
16530 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
16531 (Fnext_overlay_change, Fprevious_overlay_change)
16532 (mouse_face_overlay_overlaps, Foverlays_in):
16533 Use ptrdiff_t, not int, for sizes.
16534 (overlays_at, overlays_in): Check for size-calculation overflow.
16536 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
16538 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
16539 (x_session_initialize): Do not assume string length fits in int.
16541 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
16542 This is unlikely, but can occur if DPI is outlandish.
16544 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
16545 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
16547 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
16548 * xrdb.c (magic_file_p, search_magic_path):
16549 Omit last arg SUFFIX; it was always 0. All callers changed.
16550 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
16552 * xfont.c (xfont_match): Avoid need for strlen.
16554 * xfns.c: Don't assume strlen fits in int.
16555 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
16557 * xdisp.c (message_log_check_duplicate): Return intmax_t,
16558 not unsigned long, as we prefer signed integers. All callers changed.
16559 Detect integer overflow in repeat count.
16560 (message_dolog): Don't assume print length fits in 39 bytes.
16561 (display_mode_element): Don't assume strlen fits in int.
16563 * termcap.c: Don't assume sizes fit in int and never overflow.
16564 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
16565 (gobble_line): Check for size-calculation overflow.
16567 * minibuf.c (Fread_buffer):
16568 * lread.c (intern, intern_c_string):
16569 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
16570 Don't assume string length fits in int.
16572 * keyboard.c (parse_tool_bar_item):
16573 * gtkutil.c (style_changed_cb): Avoid need for strlen.
16575 * font.c: Don't assume string length fits in int.
16576 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
16577 Use ptrdiff_t, not int.
16578 (font_intern_prop): Don't assume string length fits in int.
16579 Don't assume integer property fits in fixnum.
16580 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
16582 * filelock.c: Fix some buffer overrun and integer overflow issues.
16583 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
16584 Reformulate so as not to need the command string.
16585 Invoke gzip -cd rather than gunzip, as it's more portable.
16586 (lock_info_type, lock_file_1, lock_file):
16587 Don't assume pid_t and time_t fit in unsigned long.
16588 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
16589 (current_lock_owner): Prefer signed type for sizes.
16590 Use memcpy, not strncpy, where memcpy is what is really wanted.
16591 Don't assume (via atoi) that time_t and pid_t fit in int.
16592 Check for time_t and/or pid_t out of range, e.g., via a network share.
16593 Don't alloca where an auto var works fine.
16595 * fileio.c: Fix some integer overflow issues.
16596 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
16597 Don't assume string length fits in int.
16598 (directory_file_name): Don't assume string length fits in long.
16599 (make_temp_name): Don't assume pid fits in int, or that its print
16600 length is less than 20.
16602 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
16604 * coding.c (make_subsidiaries): Don't assume string length fits in int.
16606 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
16608 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
16609 We prefer signed integers, even for size calculations.
16611 * emacs.c: Don't assume string length fits in 'int'.
16612 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
16613 (main): Don't invoke strlen when not needed.
16615 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
16616 (XD_DEBUG_MESSAGE): Don't waste a byte.
16618 * callproc.c (getenv_internal_1, getenv_internal)
16619 (Fgetenv_internal):
16620 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
16622 * lread.c (invalid_syntax): Omit length argument.
16623 All uses changed. This doesn't fix a bug, but it simplifies the
16624 code away from its former Hollerith-constant appearance, and it's
16625 one less 'int' to worry about when looking at integer-overflow issues.
16626 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
16628 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
16629 This didn't break anything, but it didn't help either.
16630 It's confusing to put a bogus integer in a place where the actual
16631 value does not matter.
16632 (LIST_END_P): Remove unused macro and its bogus comment.
16633 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
16635 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
16636 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
16638 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
16639 We prefer signed types, and the value cannot exceed the EMACS_INT
16640 range anyway (because otherwise the length would not be representable).
16641 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
16642 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
16643 This avoids a GCC warning when WIDE_EMACS_INT.
16645 * indent.c (sane_tab_width): New function.
16646 (current_column, scan_for_column, Findent_to, position_indentation)
16647 (compute_motion): Use it. This is just for clarity.
16648 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
16650 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
16652 * lisp.h (lint_assume): New macro.
16653 * composite.c (composition_gstring_put_cache):
16654 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
16656 * editfns.c, insdel.c:
16657 Omit unnecessary forward decls, to simplify future changes.
16659 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
16661 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
16663 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
16664 Use much-faster test for byte-length change.
16665 Don't assume string byte-length fits in 'int'.
16666 Check that character arg fits in 'int'.
16667 (mapcar1): Declare byte as byte, for clarity.
16669 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
16671 * fns.c (concat): Catch string overflow earlier.
16672 Do not rely on integer wraparound.
16674 * dispextern.h (struct it.overlay_strings_charpos)
16675 (struct it.selective): Now EMACS_INT, not int.
16676 * xdisp.c (forward_to_next_line_start)
16677 (back_to_previous_visible_line_start)
16678 (reseat_at_next_visible_line_start, next_element_from_buffer):
16679 Don't arbitrarily truncate the value of 'selective' to int.
16681 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
16683 * composite.c: Don't truncate sizes to 'int'.
16684 (composition_gstring_p, composition_reseat_it)
16685 (composition_adjust_point): Use EMACS_INT, not int.
16686 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
16687 not EMACS_UINT, for indexes.
16689 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
16691 * buffer.c: Include <verify.h>.
16692 (struct sortvec.priority, struct sortstr.priority):
16693 Now EMACS_INT, not int.
16694 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
16695 (struct sortstr.size, record_overlay_string)
16696 (struct sortstrlist.size, struct sortlist.used):
16697 Don't truncate size to int.
16698 (record_overlay_string): Check for size-calculation overflow.
16699 (init_buffer_once): Check at compile-time, not run-time.
16701 2011-06-22 Jim Meyering <meyering@redhat.com>
16703 Don't leak an XBM-image-sized buffer
16704 * image.c (xbm_load): Free the image buffer after using it.
16706 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
16709 * composite.c (find_automatic_composition): Omit needless 'return 0;'
16710 that Sun C diagnosed.
16711 * fns.c (secure_hash): Fix pointer signedness issue.
16712 * intervals.c (static_offset_intervals): New function.
16713 (offset_intervals): Use it.
16715 2011-06-21 Leo Liu <sdl.web@gmail.com>
16718 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
16721 * fns.c (secure_hash): Rename from crypto_hash_function and change
16722 the first arg to accept symbols.
16723 (Fsecure_hash): New primitive.
16724 (syms_of_fns): New symbols.
16726 2011-06-20 Deniz Dogan <deniz@dogan.se>
16728 * process.c (Fset_process_buffer): Clarify return value in
16731 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
16733 * dispnew.c (add_window_display_history): Use BVAR.
16735 * xdisp.c (debug_method_add): Use BVAR.
16736 (check_window_end, dump_glyph_matrix, dump_glyph)
16737 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
16739 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
16742 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
16743 check till after the cache is created in init_frame_faces.
16745 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
16747 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
16749 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
16751 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
16752 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
16753 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
16755 Improve buffer-overflow checking (Bug#8873).
16756 * fileio.c (Finsert_file_contents):
16757 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
16758 Remove the old (too-loose) buffer overflow checks.
16759 They weren't needed, since make_gap checks for buffer overflow.
16760 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
16761 The old code merely checked for Emacs fixnum overflow, and relied
16762 on undefined (wraparound) behavior. The new code avoids undefined
16763 behavior, and also checks for ptrdiff_t and/or size_t overflow.
16765 * editfns.c (Finsert_char): Don't dump core with very negative counts.
16766 Tune. Don't use wider integers than needed. Don't use alloca.
16767 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
16769 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
16771 * insdel.c, lisp.h (buffer_overflow): New function.
16772 (insert_from_buffer_1, replace_range, replace_range_2):
16773 * insdel.c (make_gap_larger):
16774 * editfns.c (Finsert_char):
16775 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
16777 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
16779 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
16781 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
16783 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
16784 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
16786 * fileio.c: Don't assume EMACS_INT fits in off_t.
16787 (emacs_lseek): New static function.
16788 (Finsert_file_contents, Fwrite_region): Use it.
16789 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
16791 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
16793 * fns.c: Don't overflow int when computing a list length.
16794 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
16795 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
16796 truncation on 64-bit hosts. Check for QUIT every
16797 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
16798 faster and is responsive enough.
16799 (Flength): Report an error instead of overflowing an integer.
16800 (Fsafe_length): Return a float if the value is not representable
16801 as a fixnum. This shouldn't happen except in contrived situations.
16802 (Fnthcdr, Fsort): Don't assume list length fits in int.
16803 (Fcopy_sequence): Don't assume vector length fits in int.
16805 * alloc.c: Check that resized vectors' lengths fit in fixnums.
16806 (header_size, word_size): New constants.
16807 (allocate_vectorlike): Don't check size overflow here.
16808 (allocate_vector): Check it here instead, since this is the only
16809 caller of allocate_vectorlike that could cause overflow.
16810 Check that the new vector's length is representable as a fixnum.
16812 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
16813 The previous code was bogus. For example, next_almost_prime (32)
16814 returned 39, which is undesirable as it is a multiple of 3; and
16815 next_almost_prime (24) returned 25, which is a multiple of 5 so
16816 why was the code bothering to check for multiples of 7?
16818 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
16820 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
16822 Variadic C functions now count arguments with ptrdiff_t.
16823 This partly undoes my 2011-03-30 change, which replaced int with size_t.
16824 Back then I didn't know that the Emacs coding style prefers signed int.
16825 Also, in the meantime I found a few more instances where arguments
16826 were being counted with int, which may truncate counts on 64-bit
16827 machines, or EMACS_INT, which may be unnecessarily wide.
16828 * lisp.h (struct Lisp_Subr.function.aMANY)
16829 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
16830 Arg counts are now ptrdiff_t, not size_t.
16831 All variadic functions and their callers changed accordingly.
16832 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
16833 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
16834 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
16835 * callint.c (Fcall_interactively): Check arg count for overflow,
16836 to avoid potential buffer overrun. Use signed char, not 'int',
16837 for 'varies' array, so that we needn't bother to check its size
16838 calculation for overflow.
16839 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
16840 * eval.c (apply_lambda):
16841 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
16842 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
16843 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
16845 * callint.c (Fcall_interactively): Don't use index var as event count.
16847 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
16848 * mem-limits.h (SIZE): Remove; no longer used.
16850 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
16852 Remove unnecessary casts.
16853 * xterm.c (x_term_init):
16854 * xfns.c (x_set_border_pixel):
16855 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
16856 These aren't needed now that we assume ANSI C.
16858 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
16859 It's more likely to cause problems (due to unsigned overflow)
16862 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
16864 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
16866 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
16868 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
16870 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
16872 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
16874 GLYPH_CODE_FACE returns EMACS_INT, not int.
16875 * dispextern.h (merge_faces):
16876 * xfaces.c (merge_faces):
16877 * xdisp.c (get_next_display_element, next_element_from_display_vector):
16878 Don't assume EMACS_INT fits in int.
16880 * character.h (CHAR_VALID_P): Remove unused parameter.
16881 * fontset.c, lisp.h, xdisp.c: All uses changed.
16883 * editfns.c (Ftranslate_region_internal): Omit redundant test.
16885 * fns.c (concat): Minor tuning based on overflow analysis.
16886 This doesn't fix any bugs. Use int to hold character, instead
16887 of constantly refetching from Emacs object. Use XFASTINT, not
16888 XINT, for value known to be a character. Don't bother comparing
16889 a single byte to 0400, as it's always less.
16891 * floatfns.c (Fexpt):
16892 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
16894 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
16897 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
16899 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
16900 Without this fix, on a 64-bit host (aset S 0 4294967386) would
16901 incorrectly succeed when S was a string, because 4294967386 was
16902 truncated before it was used.
16904 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
16905 Otherwise, an out-of-range integer could cause undefined behavior
16908 * composite.c: Use int, not EMACS_INT, for characters.
16909 (fill_gstring_body, composition_compute_stop_pos): Use int, not
16910 EMACS_INT, for values that are known to be in character range.
16911 This doesn't fix any bugs but is the usual style inside Emacs and
16912 may generate better code on 32-bit machines.
16914 Make sure a 64-bit char is never passed to ENCODE_CHAR.
16915 This is for reasons similar to the recent CHAR_STRING fix.
16916 * charset.c (Fencode_char): Check that character arg is actually
16917 a character. Pass an int to ENCODE_CHAR.
16918 * charset.h (ENCODE_CHAR): Verify that the character argument is no
16919 wider than 'int', as a compile-time check to prevent future regressions
16922 * character.c (char_string): Remove unnecessary casts.
16924 Make sure a 64-bit char is never passed to CHAR_STRING.
16925 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
16926 by silently ignoring the top 32 bits, allowing some values
16927 that were far too large to be valid characters.
16928 * character.h: Include <verify.h>.
16929 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
16930 arguments are no wider than unsigned, as a compile-time check
16931 to prevent future regressions in this area.
16933 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
16934 (Fsubst_char_in_region):
16936 * xdisp.c (decode_mode_spec_coding):
16937 Adjust to CHAR_STRING's new requirement.
16938 * editfns.c (Finsert_char, Fsubst_char_in_region):
16939 * fns.c (concat): Check that character args are actually
16940 characters. Without this test, these functions did the wrong
16941 thing with wildly out-of-range values on 64-bit hosts.
16943 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
16944 These casts should not be needed on 32-bit hosts, either.
16945 * keyboard.c (read_char):
16946 * lread.c (Fload): Remove casts to unsigned.
16948 * lisp.h (UNSIGNED_CMP): New macro.
16949 This fixes comparison bugs on 64-bit hosts.
16950 (ASCII_CHAR_P): Use it.
16951 * casefiddle.c (casify_object):
16952 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
16953 (SINGLE_BYTE_CHAR_P, CHAR_STRING):

17006 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
17007 when a (possibly-narrower) signed value would do just as well.
17008 We prefer using signed arithmetic, to avoid comparison confusion.
17010 * alloc.c: Catch some string size overflows that we were missing.
17011 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
17012 for convenience in STRING_BYTES_MAX.
17013 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
17014 The definition here is exact; the one in lisp.h was approximate.
17015 (allocate_string_data): Check for string overflow. This catches
17016 some instances we weren't catching before. Also, it catches
17017 size_t overflow on (unusual) hosts where SIZE_MAX <= min
17018 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
17019 and ptrdiff_t and EMACS_INT are both 64 bits.
17021 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
17022 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

17600 instead of using explicit *_CHAR codes.
17601 (bidi_resolve_explicit, bidi_resolve_weak):

17610 (bidi_level_of_next_char): Don't try to lookup the cache for the
17611 next/previous character if nothing is cached there yet, or if we
17612 were just reseat()'ed to a new position.
17614 * xdisp.c (set_cursor_from_row): Set start and stop points
17615 according to the row's direction when priming the loop that looks
17616 for the glyph on which to display cursor.

17618 (display_prop_intangible_p): Reimplement to call
17619 handle_display_spec instead of single_display_spec_intangible_p.
17620 Accept 3 additional arguments needed by handle_display_spec.
17621 This fixes incorrect cursor motion across display property with complex
17622 values: lists, `(when COND...)' forms, etc.

17630 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
17631 value of a `display' property is a "replacing spec".
17632 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
17633 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
17634 the display property, but just return a value indicating whether
17635 the display property will replace the characters it covers.
17636 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
17637 frame_window_p members of struct bidi_it.
17638 (compute_display_string_pos, compute_display_string_end):

17661 All callers changed. (Bug#8762)
17663 * gnutls.c: Use Emacs's memory allocators.
17664 Without this change, the gnutls library would invoke malloc etc.
17665 directly, which causes problems on non-SYNC_INPUT hosts, and which
17666 runs afoul of improving memory_full behavior. (Bug#8761)
17667 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
17668 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
17669 xfree instead of the default malloc, realloc, free.
17670 (Fgnutls_boot): No need to check for memory allocation failure,
17671 since xmalloc does that for us.

17693 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
17694 for hashes and hash indexes, instead of 'unsigned' and 'int'.
17695 * alloc.c (allocate_vectorlike):
17696 Check for overflow in vector size calculations.
17697 * ccl.c (ccl_driver):
17698 Check for overflow when converting EMACS_INT to int.

17700 need to be updated by these changes.
17701 * fns.c (make_hash_table, maybe_resize_hash_table):
17702 Check for integer overflow with large hash tables.
17703 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
17704 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
17705 (SXHASH_REDUCE): New macro.
17706 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
17707 Use it instead of discarding useful hash info with large hash values.
17708 (sxhash_float): New function.
17709 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
17710 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
17711 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
17712 Rewrite to use FIXNUM_BITS, as this simplifies things.
17713 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
17714 Adjust signatures to match updated version of code.
17715 (consing_since_gc): Now EMACS_INT, since a single hash table can
17716 use more than INT_MAX bytes.

17765 Make it possible to run ./temacs.
17767 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
17768 syms_of_callproc does the same thing. Remove test for

17826 2011-05-28 Jim Meyering <meyering@redhat.com>
17828 Avoid a sign-extension bug in crypto_hash_function.
17829 * fns.c (to_uchar): Define.
17830 (crypto_hash_function): Use it to convert some newly-signed
17831 variables to unsigned, to avoid sign-extension bugs. For example,
17832 without this change, (md5 "truc") would evaluate to
17833 45723a2aff78ff4fff7fff1114760e62 rather than the expected
17834 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
17835 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
17837 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17839 Integer overflow fixes.
17841 * dbusbind.c: Serial number integer overflow fixes.
17842 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
17843 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
17844 to hold a serial number that is too large for a fixnum.
17845 (Fdbus_method_return_internal, Fdbus_method_error_internal):
17846 Check for serial numbers out of range. Decode any serial number
17847 that was so large that it became a float. (Bug#8722)
17849 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
17850 (Fdbus_call_method, Fdbus_call_method_asynchronously):
17851 Use XFASTINT rather than XUINT when numbers are nonnegative.
17852 (xd_append_arg, Fdbus_method_return_internal):
17853 (Fdbus_method_error_internal): Likewise. Also, for unsigned
17854 arguments, check that Lisp number is nonnegative, rather than
17855 silently wrapping negative numbers around. (Bug#8722)
17856 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
17859 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
17861 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
17863 ccl: Add integer overflow checks.
17864 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
17865 (IN_INT_RANGE): New macros.
17866 (ccl_driver): Use them to check for integer overflow when
17867 decoding a CCL program. Many of the new checks are whether XINT (x)
17868 fits in int; it doesn't always, on 64-bit hosts. The new version
17869 doesn't catch all possible integer overflows, but it's an
17870 improvement. (Bug#8719)
17872 * alloc.c (make_event_array): Use XINT, not XUINT.
17873 There's no need for unsigned here.
17875 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
17876 This follows up to the 2011-05-06 change that substituted uintptr_t
17877 for EMACS_INT. This case wasn't caught back then.
17879 Rework Fformat to avoid integer overflow issues.
17880 * editfns.c: Include <float.h> unconditionally, as it's everywhere
17881 now (part of C89). Include <verify.h>.
17882 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
17883 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
17884 (Fformat): Avoid the prepass trying to compute sizes; it was only
17885 approximate and thus did not catch overflow reliably. Instead, walk
17886 through the format just once, formatting and computing sizes as we go,
17887 checking for integer overflow at every step, and allocating a larger
17888 buffer as needed. Keep track separately whether the format is
17889 multibyte. Keep only the most-recently calculated precision, rather
17890 than them all. Record whether each argument has been converted to
17891 string. Use EMACS_INT, not int, for byte and char and arg counts.
17892 Support field widths and precisions larger than INT_MAX. Avoid
17893 sprintf's undefined behavior with conversion specifications such as %#d
17894 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
17895 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
17896 formatting out-of-range floating point numbers with int
17897 formats. (Bug#8668)
17899 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
17901 * data.c: Avoid integer truncation in expressions involving floats.
17902 * data.c: Include <intprops.h>.
17903 (arith_driver): When there's an integer overflow in an expression
17904 involving floating point, convert the integers to floating point
17905 so that the resulting value does not suffer from catastrophic
17906 integer truncation. For example, on a 64-bit host (* 4
17907 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
17908 Do not rely on undefined behavior after integer overflow.
17910 merge count_size_as_multibyte, parse_str_to_multibyte
17911 * character.c, character.h (count_size_as_multibyte):
17912 Rename from parse_str_to_multibyte; all uses changed.
17913 Check for integer overflow.
17914 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
17915 since it's now a duplicate of the other. This is more of
17916 a character than a buffer op, so better that it's in character.c.
17917 * fns.c, print.c: Adjust to above changes.
17919 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
17921 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
17923 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
17925 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17926 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
17927 (x_clipboard_manager_save): Now static.
17928 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
17930 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
17931 (crypto_hash_function): Now static.
17932 Fix pointer signedness problems. Avoid unnecessary initializations.
17934 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
17936 * termhooks.h (Vselection_alist): Make it terminal-local.
17938 * terminal.c (create_terminal): Initialize it.
17940 * xselect.c: Support for clipboard managers.
17941 (Vselection_alist): Move to termhooks.h as terminal-local var.
17942 (LOCAL_SELECTION): New macro.
17943 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
17944 (symbol_to_x_atom): Remove gratuitous arg.
17945 (x_handle_selection_request, lisp_data_to_selection_data)
17946 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
17947 (x_own_selection, x_get_local_selection, x_convert_selection):
17948 New arg, specifying work frame. Use terminal-local Vselection_alist.
17949 (some_frame_on_display): Delete unused function.
17950 (Fx_own_selection_internal, Fx_get_selection_internal)
17951 (Fx_disown_selection_internal, Fx_selection_owner_p)
17952 (Fx_selection_exists_p): New optional frame arg.
17953 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
17954 (x_handle_selection_clear): Don't treat other terminals with the
17955 same keyboard specially. Use the terminal-local Vselection_alist.
17956 (x_clear_frame_selections): Use Frun_hook_with_args.
17958 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
17960 * xterm.h: Add support for those atoms.
17962 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
17964 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
17965 (converted_selections, conversion_fail_tag): New global variables.
17966 (x_selection_request_lisp_error): Free the above.
17967 (x_get_local_selection): Remove unnecessary code.
17968 (x_reply_selection_request): Args changed; handle arbitrary array
17969 of converted selections stored in converted_selections.
17970 Separate the XChangeProperty and SelectionNotify steps.
17971 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
17972 (x_convert_selection): New function.
17973 (x_handle_selection_event): Simplify.
17974 (x_get_foreign_selection): Don't ignore incoming requests while
17975 waiting for an answer; this will fail when we implement
17976 SAVE_TARGETS, and seems unnecessary anyway.
17977 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
17978 (Vx_sent_selection_functions): Doc fix.
17980 2011-05-26 Leo Liu <sdl.web@gmail.com>
17982 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
17984 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17986 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
17988 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
17989 for fringe update if it has periodic bitmap.
17990 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
17991 and fringe_bitmap_periodic_p.
17993 * fringe.c (get_fringe_bitmap_data): New function.
17994 (draw_fringe_bitmap_1, update_window_fringes): Use it.
17995 (update_window_fringes): Record periodicity of fringe bitmap in glyph
17996 row. Mark glyph row for fringe update if periodicity changed.
17998 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
17999 for fringe update unless it has periodic bitmap.
18001 2011-05-25 Kenichi Handa <handa@m17n.org>
18003 * xdisp.c (get_next_display_element): Set correct it->face_id for
18004 a static composition.
18006 2011-05-24 Leo Liu <sdl.web@gmail.com>
18009 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
18011 * fns.c (crypto_hash_function, Fsha1): New function.
18012 (Fmd5): Use crypto_hash_function.
18013 (syms_of_fns): Add Ssha1.
18015 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18017 * gnutls.c: Remove unused macros.
18018 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
18019 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
18020 Remove macros that are defined and never used.
18021 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
18023 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18025 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
18026 (Fx_get_selection_internal): Minor cleanup.
18027 (Fx_own_selection_internal): Rename arguments for consistency with
18030 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18032 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
18034 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
18036 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
18038 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18040 * dispnew.c (scrolling_window): Don't exclude the case that the
18041 last enabled row in the desired matrix touches the bottom boundary.
18043 2011-05-21 Glenn Morris <rgm@gnu.org>
18045 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
18046 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
18047 and add some more files.
18049 2011-05-20 Eli Zaretskii <eliz@gnu.org>
18051 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
18052 report_file_error introduced by the change from 2011-05-07.
18054 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
18056 * systime.h (Time): Define only if emacs is defined.
18057 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
18058 where the include path doesn't have X11/X.h by default. See
18059 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
18061 2011-05-20 Kenichi Handa <handa@m17n.org>
18063 * composite.c (find_automatic_composition): Fix previous change.
18065 2011-05-20 Glenn Morris <rgm@gnu.org>
18067 * lisp.mk: New file, split from Makefile.in.
18068 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
18069 (shortlisp): Remove.
18070 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
18072 2011-05-19 Glenn Morris <rgm@gnu.org>
18074 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
18075 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
18076 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
18077 (lisp): Set the order to that of loadup.el.
18078 (shortlisp): Make it a copy of $lisp.
18079 (SOME_MACHINE_LISP): Remove.
18080 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
18081 Use just $shortlisp, not $SOME_MACHINE_LISP too.
18083 2011-05-18 Kenichi Handa <handa@m17n.org>
18085 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
18086 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
18087 (find_automatic_composition): Mostly rewrite for efficiency.
18089 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
18091 * makefile.w32-in: Update dependencies.
18093 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
18095 * menu.c: Include limits.h (fixes the MS-Windows build broken by
18096 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
18098 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
18100 Fix some integer overflow issues, such as string length overflow.
18102 * insdel.c (count_size_as_multibyte): Check for string overflow.
18104 * character.c (lisp_string_width): Check for string overflow.
18105 Use EMACS_INT, not int, for string indexes and lengths; in
18106 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
18107 the resulting string length overflows an EMACS_INT; instead,
18108 report a string overflow if no precision given. When checking for
18109 precision exhaustion, use a check that cannot possibly have
18110 integer overflow. (Bug#8675)
18111 * character.h (lisp_string_width): Adjust to new signature.
18113 * alloc.c (string_overflow): New function.
18114 (Fmake_string): Use it. This doesn't change behavior, but saves
18115 a few bytes and will simplify future changes.
18116 * character.c (string_escape_byte8): Likewise.
18117 * lisp.h (string_overflow): New decl.
18119 Fixups, following up to the user-interface timestamp change.
18120 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
18121 for UI timestamps, instead of unsigned long.
18122 * msdos.c (mouse_get_pos): Likewise.
18123 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
18124 * w32gui.h (Time): Define by including "systime.h" rather than by
18125 declaring it ourselves. (Bug#8664)
18127 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
18128 * image.c (clear_image_cache): Likewise.
18130 * term.c (term_mouse_position): Don't assume time_t wraparound.
18132 Be more systematic about user-interface timestamps.
18133 Before, the code sometimes used 'Time', sometimes 'unsigned long',
18134 and sometimes 'EMACS_UINT', to represent these timestamps.
18135 This change causes it to use 'Time' uniformly, as that's what X uses.
18136 This makes the code easier to follow, and makes it easier to catch
18137 integer overflow bugs such as Bug#8664.
18138 * frame.c (Fmouse_position, Fmouse_pixel_position):
18139 Use Time, not unsigned long, for user-interface timestamps.
18140 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
18141 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
18142 * keyboard.h (last_event_timestamp): Likewise.
18143 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
18144 * menu.h (xmenu_show): Likewise.
18145 * term.c (term_mouse_position): Likewise.
18146 * termhooks.h (struct input_event.timestamp): Likewise.
18147 (struct terminal.mouse_position_hook): Likewise.
18148 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
18149 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
18150 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
18151 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
18152 what it was before.
18153 * menu.h, termhooks.h: Include "systime.h", for Time.
18155 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
18156 Don't assume that the difference between two unsigned long values
18157 can fit into an integer. At this point, we know button_down_time
18158 <= event->timestamp, so the difference must be nonnegative, so
18159 there's no need to cast the result if double-click-time is
18160 nonnegative, as it should be; check that it's nonnegative, just in
18161 case. This bug is triggered when events are more than 2**31 ms
18162 apart (about 25 days). (Bug#8664)
18164 * xselect.c (last_event_timestamp): Remove duplicate decl.
18165 (x_own_selection): Remove needless cast to unsigned long.
18167 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
18168 that always fit in int. Use a sentinel instead of a counter, to
18169 avoid a temp and to allay GCC's concerns about possible int overflow.
18170 * frame.h (struct frame): Use int for menu_bar_items_used
18171 instead of EMACS_INT, since it always fits in int.
18173 * menu.c (grow_menu_items): Check for int overflow.
18175 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
18177 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
18178 Before, the code was not consistent. These values cannot exceed
18179 2**31 - 1 so there's no need to make them unsigned.
18180 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
18181 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
18182 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
18184 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
18186 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
18187 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
18188 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
18189 presumably because the widths might not match.
18191 * window.c (size_window): Avoid needless test at loop start.
18193 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
18195 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
18197 2011-05-12 Drew Adams <drew.adams@oracle.com>
18199 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
18201 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18203 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
18204 `width' to `bar_area_x' and `bar_area_width', respectively.
18205 (x_scroll_run): Take account of fringe background extension.
18207 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
18208 Rename local vars `left' and `width' to `bar_area_x' and
18209 `bar_area_width', respectively.
18210 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
18211 background extension.
18213 2011-05-10 Jim Meyering <meyering@redhat.com>
18215 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
18217 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
18219 * image.c (Finit_image_library): Return t for built-in image types,
18220 like pbm and xbm. (Bug#8640)
18222 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
18224 * w32menu.c (set_frame_menubar): Fix submenu allocation.
18226 2011-05-07 Eli Zaretskii <eliz@gnu.org>
18228 * w32console.c (Fset_screen_color): Doc fix.
18229 (Fget_screen_color): New function.
18230 (syms_of_ntterm): Defsubr it.
18232 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
18233 unlink the temporary file if Fcall_process didn't create it in the
18235 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
18236 child process will be redirected to a file specified with `:file'.
18237 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
18238 cue to call_process_cleanup not to close that handle.
18240 2011-05-07 Ben Key <bkey76@gmail.com>
18242 * makefile.w32-in: The bootstrap-temacs rule now makes use of
18243 one of two shell specific rules, either bootstrap-temacs-CMD or
18244 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
18245 to the previous implementation of the bootstrap-temacs rule.
18246 The bootstrap-temacs-CMD rule is similar to the previous
18247 implementation of the bootstrap-temacs rule except that it
18248 makes use of the ESC_CFLAGS variable instead of the CFLAGS
18251 These changes, along with some changes to nt/configure.bat,
18252 nt/gmake.defs, and nt/nmake.defs, are required to extend my
18253 earlier fix to add support for --cflags and --ldflags options
18254 that include quotes so that it works whether make uses cmd or
18257 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
18259 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
18260 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
18262 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
18263 a string. Handle both cases.
18264 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
18265 (Fdbus_register_method): Use Qinvalid_function.
18267 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18269 * makefile.w32-in: Update dependencies.
18270 (LISP_H): Add inttypes.h and stdin.h.
18271 (PROCESS_H): Add unistd.h.
18273 2011-05-06 Eli Zaretskii <eliz@gnu.org>
18275 * lread.c: Include limits.h (fixes the MS-Windows build broken by
18276 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
18278 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
18280 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
18282 * term.c (vfatal): Remove stray call to va_end.
18283 It's not needed and the C Standard doesn't allow it here anyway.
18285 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
18286 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
18288 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
18291 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
18293 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
18295 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
18297 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
18299 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
18301 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
18302 * charset.c (Fdefine_charset_internal): Don't initialize
18303 charset.code_space[15]. The value was garbage, on hosts with
18304 32-bit int (Bug#8600).
18306 * lread.c (read_integer): Be more consistent with string-to-number.
18307 Use string_to_number to do the actual conversion; this avoids
18308 rounding errors and fixes some other screwups. Without this fix,
18309 for example, #x1fffffffffffffff was misread as -2305843009213693952.
18310 (digit_to_number): Move earlier, for benefit of read_integer.
18311 Return -1 if the digit is out of range for the base, -2 if it is
18312 not a digit in any supported base. (Bug#8602)
18314 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
18316 * dispnew.c (scrolling_window): Return 1 if we scrolled,
18317 to match comment at start of function. This also removes a
18318 GCC warning about overflow in a 32+64-bit port.
18320 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
18322 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
18323 Reported by Stefan Monnier in
18324 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
18325 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18326 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
18328 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
18329 (EMACS_UINTPTR): Likewise, with uintptr_t.
18331 * lisp.h: Prefer 64-bit EMACS_INT if available.
18332 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
18333 on 32-bit hosts that have 64-bit int, so that they can access
18335 However, temporarily disable this change unless the temporary
18336 symbol WIDE_EMACS_INT is defined.
18338 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
18340 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
18341 This removes an assumption that EMACS_INT and long are the same
18342 width as pointers. The assumption is true for Emacs porting targets
18343 now, but we want to make other targets possible.
18344 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
18345 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
18346 In the rest of the code, change types of integers that hold casted
18347 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
18348 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
18349 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
18350 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
18351 No need to cast type when ORing.
18352 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
18353 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
18354 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
18355 assume EMACS_INT is the same width as char *.
18356 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
18357 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
18358 Remove no-longer-needed casts.
18359 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
18360 (xg_tool_bar_help_callback, xg_make_tool_item):
18361 Use EMACS_INTPTR to hold an integer
18362 that will be cast to void *; this can avoid a GCC warning
18363 if EMACS_INT is not the same width as void *.
18364 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
18365 * xdisp.c (display_echo_area_1, resize_mini_window_1):
18366 (current_message_1, set_message_1):
18367 Use a local to convert to proper width without a cast.
18368 * xmenu.c (dialog_selection_callback): Likewise.
18370 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
18371 Also, don't assume VALBITS / RAND_BITS is less than 5,
18372 and don't rely on undefined behavior when shifting a 1 left into
18374 * lisp.h (get_random): Change signature to match.
18376 * lread.c (hash_string): Use size_t, not int, for hash computation.
18377 Normally we prefer signed values; but hashing is special, because
18378 it's better to use unsigned division on hash table sizes so that
18379 the remainder is nonnegative. Also, size_t is the natural width
18380 for hashing into memory. The previous code used 'int', which doesn't
18381 retain enough info to hash well into very large tables.
18382 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
18384 * dbusbind.c: Don't possibly lose pointer info when converting.
18385 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
18386 Use XPNTR rather than XHASH, so that the high-order bits of
18387 the pointer aren't lost when converting through void *.
18389 * eval.c (Fautoload): Don't double-shift a pointer.
18391 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
18393 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
18395 * gnutls.c (DEF_GNUTLS_FN):
18396 * image.c (DEF_IMGLIB_FN): Make function pointers static.
18398 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
18400 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
18403 2011-05-05 Eli Zaretskii <eliz@gnu.org>
18405 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
18406 New version that can reserve upto 2GB of heap space.
18408 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
18410 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
18412 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
18414 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
18415 `gnutls_certificate_set_x509_key_file'.
18417 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
18419 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
18420 Update dependencies.
18422 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18424 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
18425 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
18426 Remove unused parameter `fildes'.
18427 * process.c (read_process_output, send_process): Don't pass it.
18429 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18431 Fix previous change: the library cache is defined in w32.c.
18432 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
18433 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
18435 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
18437 Implement dynamic loading of GnuTLS on Windows.
18439 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
18440 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
18441 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18444 * gnutls.c (Qgnutls_dll): Define.
18445 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
18446 (gnutls_*): Declare function pointers.
18447 (init_gnutls_functions): New function to initialize function pointers.

18450 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
18451 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
18452 (emacs_gnutls_write, emacs_gnutls_read)
18453 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
18454 (Fgnutls_available_p): New function.
18455 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

18467 * w32.c (QCloaded_from, Vlibrary_cache): Define.
18468 (w32_delayed_load): Move from image.c. When loading a library, record
18469 its filename in the :loaded-from property of the library id.
18470 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
18471 Initialize and staticpro them.
18472 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
18474 * process.c: Include lisp.h before w32.h, not after.
18475 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
18476 instead of gnutls_record_check_pending.
18478 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
18480 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
18482 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
18483 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
18486 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
18488 * xterm.c (x_set_frame_alpha): Do not set property on anything
18489 else than FRAME_X_OUTER_WINDOW (Bug#8608).
18491 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18493 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
18495 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
18497 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

18507 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
18509 * callproc.c: Indentation fixup.
18511 * sysdep.c (wait_for_termination_1): Make static.
18512 (wait_for_termination, interruptible_wait_for_termination):
18513 Move after wait_for_termination_1.
18515 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
18517 * sysdep.c (interruptible_wait_for_termination): New function
18518 which is like wait_for_termination, but allows keyboard
18521 * callproc.c (Fcall_process): Add (:file "file") as an option for
18523 (Fcall_process_region): Ditto.
18525 2011-04-30 Eli Zaretskii <eliz@gnu.org>
18527 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
18528 rather than `XVECTOR (FOO)->size'.
18530 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
18531 inttypes.h, as a gnulib replacement is used if it not available in
18534 2011-04-21 Eli Zaretskii <eliz@gnu.org>
18536 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
18537 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
18538 of MOST_POSITIVE_FIXNUM. (Bug#8528)
18540 * coding.c (coding_alloc_by_realloc): Error out if destination
18541 will grow beyond MOST_POSITIVE_FIXNUM.
18542 (decode_coding_emacs_mule): Abort if there isn't enough place in
18543 charbuf for the composition carryover bytes. Reserve an extra
18544 space for up to 2 characters produced in a loop.
18545 (decode_coding_iso_2022): Abort if there isn't enough place in

18553 %llo or %llx format is passed. (Bug#8545)
18555 * window.c (window_scroll_line_based): Use a marker instead of
18556 simple variables to record original value of point. (Bug#7952)
18558 * doprnt.c (doprnt): Fix the case where a multibyte sequence
18559 produced by %s or %c overflows available buffer space. (Bug#8545)
18561 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
18563 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

18596 2011-04-27 Eli Zaretskii <eliz@gnu.org>
18598 Improve `doprnt' and its usage. (Bug#8545)
18599 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
18600 `format_end'. Remove support for %l as a conversion specifier.
18601 Don't use xrealloc. Improve diagnostics when the %l size modifier
18602 is used. Update the commentary.
18604 * eval.c (verror): Simplify calculation of size_t.
18606 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
18609 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
18611 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
18614 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
18616 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
18617 This makes this file independent of the recent pseudovector change.
18619 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
18621 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
18623 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
18624 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
18625 Remove unused local.
18626 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
18628 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
18629 GCC 4.6.0 optimizes based on type-based alias analysis.
18630 For example, if b is of type struct buffer * and v of type struct
18631 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
18632 != &v->size, and therefore "v->size = 1; b->size = 2; return
18633 v->size;" must therefore return 1. This assumption is incorrect
18634 for Emacs, since it type-puns struct Lisp_Vector * with many other
18635 types. To fix this problem, this patch adds a new type struct
18636 vectorlike_header that documents the constraints on layout of vectors
18637 and pseudovectors, and helps optimizing compilers not get fooled
18638 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
18639 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
18640 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
18642 (XSETPVECTYPE): Rewrite in terms of new macro.
18643 (XSETPVECTYPESIZE): New macro, specifying both type and size.
18644 This is a bit clearer, and further avoids the possibility of
18645 undesirable aliasing.
18646 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
18647 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
18648 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
18649 since Lisp_Subr is a special case (no "next" field).
18650 (ASIZE): Now uses header.size rather than size.
18651 All previous uses of XVECTOR (foo)->size replaced to use this macro,
18652 to avoid the hassle of writing XVECTOR (foo)->header.size.
18653 (struct vectorlike_header): New type.
18654 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
18655 object, to help avoid aliasing.
18656 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
18657 (SUBRP): Likewise, since Lisp_Subr is a special case.
18658 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
18659 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
18660 (struct Lisp_Hash_Table): Combine first two members into a single
18661 struct vectorlike_header member. All uses of "size" and "next" members
18662 changed to be "header.size" and "header.next".
18663 * buffer.h (struct buffer): Likewise.
18664 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
18665 * frame.h (struct frame): Likewise.
18666 * process.h (struct Lisp_Process): Likewise.
18667 * termhooks.h (struct terminal): Likewise.
18668 * window.c (struct save_window_data, struct saved_window): Likewise.
18669 * window.h (struct window): Likewise.
18670 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
18671 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
18672 * buffer.c (init_buffer_once): Likewise.
18673 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
18675 * process.c (Fformat_network_address): Use local var for size,
18678 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
18680 Make the Lisp reader and string-to-float more consistent (Bug#8525)
18681 * data.c (atof): Remove decl; no longer used or needed.
18682 (digit_to_number): Move to lread.c.
18683 (Fstring_to_number): Use new string_to_number function, to be
18684 consistent with how the Lisp reader treats infinities and NaNs.
18685 Do not assume that floating-point numbers represent EMACS_INT
18686 without losing information; this is not true on most 64-bit hosts.
18687 Avoid double-rounding errors, by insisting on integers when
18688 parsing non-base-10 numbers, as the documentation specifies.
18689 * lisp.h (string_to_number): New decl, replacing ...
18690 (isfloat_string): Remove.
18691 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
18692 (read1): Do not accept +. and -. as integers; this
18693 appears to have been a coding error. Similarly, do not accept
18694 strings like +-1e0 as floating point numbers. Do not report
18695 overflow for integer overflows unless the base is not 10 which
18696 means we have no simple and reliable way to continue.
18697 Break out the floating-point parsing into a new
18698 function string_to_number, so that Fstring_to_number parses
18699 floating point numbers consistently with the Lisp reader.
18700 (digit_to_number): Move here from data.c. Make it static inline.
18701 (E_CHAR, EXP_INT): Remove, replacing with ...
18702 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
18703 (string_to_number): New function, replacing isfloat_string.
18704 This function checks for valid syntax and produces the resulting
18705 Lisp float number too. Rework it so that string-to-number
18706 no longer mishandles examples like "1.0e+". Use strtoumax,
18707 so that overflow for non-base-10 numbers is reported only when
18708 there's no portable and simple way to convert to floating point.
18710 * textprop.c (set_text_properties_1): Rewrite for clarity,
18711 and to avoid GCC warning about integer overflow.
18713 * intervals.h (struct interval): Use EMACS_INT for members
18714 where EMACS_UINT might cause problems. See
18715 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
18716 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
18717 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
18719 (offset_intervals): Tell GCC not to worry about length overflow
18720 when negating a negative length.
18722 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
18723 (overrun_check_free): Likewise.
18725 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
18726 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
18729 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18730 (gnutls_make_error): Rename local to avoid shadowing.
18731 (gnutls_emacs_global_deinit): ifdef out; not used.
18732 (Fgnutls_boot): Use const for pointer to readonly storage.
18733 Comment out unused local. Fix pointer signedness problems.
18735 * lread.c (openp): Don't stuff size_t into an 'int'.
18736 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
18737 about possible signed overflow.
18739 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
18740 (GDK_KEY_g): Don't define if already defined.
18741 (xg_prepare_tooltip): Avoid pointer signedness problem.
18742 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
18744 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
18745 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
18747 * xfns.c (Fx_window_property): Simplify a bit,
18748 to make a bit faster and to avoid GCC 4.6.0 warning.
18749 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
18751 * fns.c (internal_equal): Don't assume size_t fits in int.
18753 * alloc.c (compact_small_strings): Tighten assertion a little.
18755 Replace pEd with more-general pI, and fix some printf arg casts.
18756 * lisp.h (pI): New macro, generalizing old pEd macro to other
18757 conversion specifiers. For example, use "...%"pI"d..." rather
18758 than "...%"pEd"...".
18759 (pEd): Remove. All uses replaced with similar uses of pI.
18760 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
18761 * alloc.c (check_pure_size): Don't overflow by converting size to int.
18762 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
18763 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
18764 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
18765 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
18766 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
18768 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
18769 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
18770 * print.c (safe_debug_print, print_object): Likewise.
18771 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
18773 Use pI instead of if-then-else-abort. Use %p to avoid casts,
18774 avoiding the 0 flag, which is not portable.
18775 * process.c (Fmake_network_process): Use pI to avoid cast.
18776 * region-cache.c (pp_cache): Likewise.
18777 * xdisp.c (decode_mode_spec): Likewise.
18778 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
18779 behavior on 64-bit hosts with printf arg.
18780 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
18781 (x_stop_queuing_selection_requests): Likewise.
18782 (x_get_window_property): Don't truncate byte count to an 'int'
18785 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
18786 here, since it parses constructs like leading '-' and spaces,
18787 which are not wanted; and it overflows with large numbers.
18788 Instead, simply match F[0-9]+, which is what is wanted anyway.
18790 * alloc.c: Remove unportable assumptions about struct layout.
18791 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
18792 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
18793 (allocate_vectorlike, make_pure_vector): Use the new macros,
18794 plus offsetof, to remove unportable assumptions about struct layout.
18795 These assumptions hold on all porting targets that I know of, but
18796 they are not guaranteed, they're easy to remove, and removing them
18797 makes further changes easier.
18799 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
18800 This doesn't fix a bug but makes the code clearer.
18801 (string_overrun_cookie): Now const. Use initializers that
18802 don't formally overflow signed char, to avoid warnings.
18803 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
18804 can cause Emacs to crash when string overrun checking is enabled.
18805 (allocate_buffer): Don't assume sizeof (struct buffer) is a
18806 multiple of sizeof (EMACS_INT); it need not be, if
18807 alignof(EMACS_INT) < sizeof (EMACS_INT).
18808 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
18810 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

18817 supposed to be handshaking. (Bug#8556)
18818 Reported by Paul Eggert <eggert@cs.ucla.edu>.
18820 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

18837 2011-04-25 Eli Zaretskii <eliz@gnu.org>
18839 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
18840 "cast to pointer from integer of different size".
18842 Improve doprnt and its use in verror. (Bug#8545)
18843 * doprnt.c (doprnt): Document the set of format control sequences
18844 supported by the function. Use SAFE_ALLOCA instead of always
18847 * eval.c (verror): Don't limit the buffer size at size_max-1, that
18848 is one byte too soon. Don't use xrealloc; instead xfree and
18851 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
18853 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
18856 * gnutls.c: Renamed global_initialized to
18857 gnutls_global_initialized. Added internals for the
18858 :verify-hostname-error, :verify-error, and :verify-flags
18859 parameters of `gnutls-boot' and documented those parameters in the
18860 docstring. Start callback support.
18861 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
18862 unless a fatal error occurred. Call gnutls_alert_send_appropriate

18936 (SIZE_MAX): New macro.
18937 (doprnt): Return a size_t value. 2nd arg is now size_t.
18938 Many local variables are now size_t instead of int or unsigned.
18939 Improve overflow protection. Support `l' modifier for integer
18940 conversions. Support %l conversion. Don't assume an EMACS_INT
18941 argument for integer conversions and for %c.
18943 * lisp.h (doprnt): Restore prototype.
18945 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
18946 $(SRC)/character.h.
18948 * Makefile.in (base_obj): Add back doprnt.o.
18950 * deps.mk (doprnt.o): Add back prerequisites.
18951 (callint.o): Depend on character.h.
18953 * eval.c (internal_lisp_condition_case): Include the handler
18954 representation in the error message.

18960 * callint.c (Fcall_interactively): When displaying error message
18961 about invalid control letter, pass the character's codepoint, not
18962 a pointer to its multibyte form. Improve display of the character
18963 in octal and display also its hex code.
18965 * character.c (char_string): Use %x to display the (unsigned)
18966 codepoint of an invalid character, to avoid displaying a bogus
18969 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
18970 `error', not SYMBOL_NAME itself.
18972 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
18973 character arguments to `error'.
18975 * charset.c (check_iso_charset_parameter): Fix incorrect argument
18976 to `error' in error message about FINAL_CHAR argument. Make sure
18977 FINAL_CHAR is a character, and use %c when it is passed as

19048 * dispextern.h (struct redisplay_interface): Rename param
19049 to avoid shadowing.
19050 * termhooks.h (struct terminal): Likewise.

19054 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
19056 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
19059 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
19060 so that we aren't warned about unused symbols.
19062 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.

19077 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
19079 * xmenu.c (menu_help_callback): Pointer type fixes.

19097 compatible char. Avoid the old compiler warnings about
19098 out-of-range initializers by using, for example, '\xab' rather
19101 * xgselect.c (xgselect_initialize): Check vs interface
19102 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

19167 * nsfont.m: Fixed bugs in ns_get_family and
19168 ns_descriptor_to_entity that were caused by using free to
19169 deallocate memory blocks that were allocated by xmalloc (via
19170 xstrdup). This caused Emacs to crash when compiled with
19171 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
19172 --enable-checking=xmallocoverrun). xfree is now used to
19173 deallocate these memory blocks.

19569 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
19570 * xmenu.c, xselect.c:
19571 Declare Q* vars static if they are not used in other modules.
19572 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
19573 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
19574 Remove decls of unexported vars.
19575 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
19577 * lisp.h (DEFINE_FUNC): Make sname 'static'.
19579 Make Emacs functions such as Fatom 'static' by default.
19580 This makes it easier for human readers (and static analyzers)
19581 to see whether these functions can be called from other modules.
19582 DEFUN now defines a static function. To make the function external
19583 so that it can be used in other C modules, use the new macro DEFUE.
19584 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
19585 (Finit_image_library):
19586 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
19587 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
19588 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
19589 Remove decls, since these functions are now static.
19590 (Funintern, Fget_internal_run_time): New decls, since these functions
19591 were already external.
19593 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
19594 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

19600 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
19601 Mark functions with DEFUE instead of DEFUN,
19602 if they are used in other modules.
19603 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
19604 decls for now-static functions.
19605 * buffer.h (Fdelete_overlay): Remove decl.
19606 * callproc.c (Fgetenv_internal): Mark as internal.
19607 * composite.c (Fremove_list_of_text_properties): Remove decl.

19611 * doc.c (Fdocumntation_property): New forward static decl.
19612 * eval.c (Ffetch_bytecode): New forward static decl.
19613 (Funintern): Remove extern decl; now in .h file where it belongs.
19614 * fileio.c (Fmake_symbolic_link): New forward static decl.
19615 * image.c (Finit_image_library): New forward static decl.
19616 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
19617 * intervals.h (Fprevious_property_change):
19618 (Fremove_list_of_text_properties): Remove decls.
19619 * keyboard.c (Fthis_command_keys): Remove decl.
19620 (Fcommand_execute): New forward static decl.
19621 * keymap.c (Flookup_key): New forward static decl.
19622 (Fcopy_keymap): Now static.
19623 * keymap.h (Flookup_key): Remove decl.

19636 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
19638 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
19641 2011-04-13 Eli Zaretskii <eliz@gnu.org>
19643 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
19644 when at ZV. (Bug#8487)
19646 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
19648 * charset.c (Fclear_charset_maps): Use xfree instead of free.
19650 * keyboard.c (parse_tool_bar_item): Likewise.
19651 * sound.c (sound_cleanup, alsa_close): Likewise.
19652 * termcap.c (tgetent): Likewise.
19653 * xfns.c (x_default_font_parameter): Likewise.
19654 * xsettings.c (read_and_apply_settings): Likewise.
19656 * alloc.c (overrun_check_malloc, overrun_check_realloc)
19657 (overrun_check_free): Protoize.
19659 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
19661 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
19662 since callers should never pass a negative size.
19663 Change the signature to match that of plain 'read' and 'write'; see
19664 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
19665 * lisp.h: Update prototypes of emacs_write and emacs_read.
19667 2011-04-11 Eli Zaretskii <eliz@gnu.org>
19669 * xdisp.c (redisplay_window): Don't try to determine the character
19670 position of the scroll margin if the window start point w->startp
19671 is outside the buffer's accessible region. (Bug#8468)
19673 2011-04-10 Eli Zaretskii <eliz@gnu.org>
19675 Fix write-region and its subroutines for buffers > 2GB.
19676 * fileio.c (a_write, e_write): Modify declaration of arguments and
19677 local variables to support buffers larger than 2GB.
19678 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
19680 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
19681 argument, local variables, and return value.
19683 * lisp.h: Update prototypes of emacs_write and emacs_read.
19685 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
19687 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
19689 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
19691 Fix more problems found by GCC 4.6.0's static checks.
19693 * xdisp.c (vmessage): Use a better test for character truncation.
19695 * charset.c (load_charset_map): <, not <=, for optimization,
19696 and to avoid potential problems with integer overflow.
19697 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
19698 * casetab.c (set_identity, shuffle): Likewise.
19699 * editfns.c (Fformat): Likewise.
19700 * syntax.c (skip_chars): Likewise.
19702 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
19703 This also lets GCC 4.6.0 generate slightly better loop code.
19705 * callint.c (Fcall_interactively): <, not <=, for optimization.
19706 (Fcall_interactively): Count the number of arguments produced,
19707 not the number of arguments given. This is simpler and lets GCC
19708 4.6.0 generate slightly better code.
19710 * ftfont.c: Distingish more carefully between FcChar8 and char.
19711 The previous code passed unsigned char * to a functions like
19712 strlen and xstrcasecmp that expect char *, which does not
19713 conform to the C standard.
19714 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
19715 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
19716 char * when the C standard requires it.
19718 * keyboard.c (read_char): Remove unused var.
19720 * eval.c: Port to Windows vsnprintf (Bug#8435).
19721 Include <limits.h>.
19722 (SIZE_MAX): Define if the headers do not.
19723 (verror): Do not give up if vsnprintf returns a negative count.
19724 Instead, grow the buffer. This ports to Windows vsnprintf, which
19725 does not conform to C99. Problem reported by Eli Zaretskii.
19726 Also, simplify the allocation scheme, by avoiding the need for
19727 calling realloc, and removing the ALLOCATED variable.
19729 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
19731 Remove invocations of doprnt, as Emacs now uses vsnprintf.
19732 But keep the doprint source code for now, as we might revamp it
19733 and use it again (Bug#8435).
19734 * lisp.h (doprnt): Remove.
19735 * Makefile.in (base_obj): Remove doprnt.o.
19736 * deps.mk (doprnt.o): Remove.
19738 error: Print 32- and 64-bit integers portably (Bug#8435).
19739 Without this change, on typical 64-bit hosts error ("...%d...", N)
19740 was used to print both 32- and 64-bit integers N, which relied on
19741 undefined behavior.
19742 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
19743 * lisp.h (error, verror): Mark as printf-like functions.
19744 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
19745 Report overflow in size calculations when allocating printf buffer.
19746 Do not truncate output string at its first null byte.
19747 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
19748 Truncate the output at a character boundary, since vsnprintf does not
19750 * charset.c (check_iso_charset_parameter): Convert internal
19751 character to string before calling 'error', since %c now has the
19753 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
19754 overflow when computing char to be passed to 'error'. Do not
19755 pass Lisp_Object to 'error'; pass the integer instead.
19756 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
19757 formatted with plain %d.
19759 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
19761 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
19763 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
19765 * xterm.c (x_catch_errors): Remove duplicate declaration.
19767 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
19769 * xdisp.c, lisp.h (message_nolog): Remove; unused.
19771 2011-04-10 Jim Meyering <meyering@redhat.com>
19773 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
19774 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
19775 return ssize_t not "int", and use size_t as the buffer length.
19776 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
19777 * gnutls.h: Update declarations.
19778 * process.c (read_process_output): Use ssize_t, to match.
19779 (send_process): Likewise.
19781 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19783 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
19785 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
19787 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
19788 Use unsigned char, to match FcChar8 type definition.
19790 * xterm.c (handle_one_xevent):
19791 * xmenu.c (create_and_show_popup_menu):
19792 * xselect.c (x_decline_selection_request)
19793 (x_reply_selection_request): Avoid type-punned deref of X events.
19795 2011-04-09 Eli Zaretskii <eliz@gnu.org>
19797 Fix some uses of `int' instead of EMACS_INT.
19798 * search.c (string_match_1, fast_string_match)
19799 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
19800 (scan_buffer, find_next_newline_no_quit)
19801 (find_before_next_newline, search_command, Freplace_match)
19802 (Fmatch_data): Make some `int' variables be EMACS_INT.
19804 * xdisp.c (display_count_lines): 3rd argument and return value now
19805 EMACS_INT. All callers changed.
19806 (pint2hrstr): Last argument is now EMACS_INT.
19808 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
19809 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
19810 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
19811 (decode_coding_utf_16, decode_coding_emacs_mule)

19813 (decode_coding_ccl, decode_coding_charset)
19814 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
19815 (decode_coding_iso_2022, decode_coding_emacs_mule)
19816 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
19817 <char_offset, last_offset>: Declare EMACS_INT.

19819 (encode_coding_emacs_mule, encode_invocation_designation)
19820 (encode_designation_at_bol, encode_coding_iso_2022)
19821 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
19822 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
19824 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
19825 (encode_invocation_designation): Last argument P_NCHARS is now
19827 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
19828 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
19830 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
19833 * ccl.c (Fccl_execute_on_string): Declare some variables
19836 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
19838 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
19840 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
19842 * process.c (Fformat_network_address): Doc fix.
19844 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
19846 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
19848 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
19850 * keyboard.c (read_char): Call Lisp function help-form-show,
19851 instead of using internal_with_output_to_temp_buffer.
19852 (Qhelp_form_show): New var.
19853 (syms_of_keyboard): Use DEFSYM macro.
19855 * print.c (internal_with_output_to_temp_buffer): Function deleted.

19859 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
19861 * process.c (Flist_processes): Remove to Lisp.
19862 (list_processes_1): Delete.
19864 2011-04-06 Eli Zaretskii <eliz@gnu.org>
19866 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
19868 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
19870 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
19872 Fix more problems found by GCC 4.6.0's static checks.
19874 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
19876 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
19878 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
19880 * xdisp.c (vmessage): Mark as a printf-like function.
19882 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
19884 * sound.c (sound_warning): Don't crash if arg contains a printf format.

19889 to system-supplied API.
19891 * eval.c (Fsignal): Remove excess argument to 'fatal'.
19893 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
19894 This avoids several warnings with gcc -Wstrict-overflow.
19895 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
19896 directly, rather than having caller test rule sign. This avoids
19897 some unnecessary tests.
19898 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
19899 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
19900 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
19902 * xfont.c (xfont_text_extents): Remove var that was set but not used.
19903 (xfont_open): Avoid unnecessary tests.
19905 * composite.c (composition_gstring_put_cache): Use unsigned integer.

19914 by using the new macro.
19916 * textprop.c (set_text_properties_1): Change while to do-while,
19917 since the condition is always true at first.
19919 * intervals.c (graft_intervals_into_buffer): Mark var as used.
19920 (interval_deletion_adjustment): Return unsigned value.
19923 * process.c (list_processes_1, create_pty, read_process_output):

19933 (update_syntax_table): Use unsigned instead of int.
19935 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
19936 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
19937 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
19939 * print.c (print_error_message): Avoid int overflow.
19941 * font.c (font_list_entities): Redo for clarity,
19942 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
19944 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
19945 (font_score): Avoid potential overflow in diff calculation.
19947 * fns.c (substring_both): Remove var that is set but not used.
19948 (sxhash): Redo loop for clarity and to avoid wraparound warning.
19950 * eval.c (funcall_lambda): Rename local to avoid shadowing.
19952 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
19953 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
19954 can always succeed if overflow has undefined behavior.
19956 * search.c (boyer_moore, wordify): Remove vars set but not used.
19957 (wordify): Omit three unnecessary tests.
19959 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
19960 All callers changed. This avoids the need for an unused var.
19962 * casefiddle.c (casify_region): Remove var that is set but not used.
19964 * dired.c (file_name_completion): Remove var that is set but not used.

19968 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
19969 (Finsert_file_contents): Remove unnecessary code checking fd.
19971 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
19972 Check for integer overflow on size calculations.
19974 * buffer.c (Fprevious_overlay_change): Remove var that is set
19977 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
19978 Remove vars that are set but not used.
19979 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
19980 (timer_check_2): Mark vars as initialized.
19982 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
19984 * image.c (lookup_image): Remove var that is set but not used.
19985 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
19987 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
19988 that are set but not used.
19990 * xfns.c (make_invisible_cursor): Don't return garbage
19991 if XCreateBitmapFromData fails (Bug#8410).
19993 * xselect.c (x_get_local_selection, x_handle_property_notify):
19994 Remove vars that are set but not used.
19996 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
19997 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
19999 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
20000 Remove var that is set but not used.
20001 (scroll_bar_windows_size): Now size_t, not int.
20002 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
20003 Check for overflow.
20005 * xfaces.c (realize_named_face): Remove vars that are set but not used.
20006 (map_tty_color) [!defined MSDOS]: Likewise.
20008 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
20010 * coding.c: Remove vars that are set but not used.
20011 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

20018 that is set but not used.
20020 * print.c (print_object): Remove var that is set but not used.
20022 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
20023 The gnulib version avoids calling malloc in the usual case,
20024 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
20025 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
20026 * filelock.c (current_lock_owner): Likewise.
20027 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
20028 * sysdep.c: Include allocator.h, careadlinkat.h.
20029 (emacs_no_realloc_allocator): New static constant.
20030 (emacs_readlink): New function.
20031 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
20032 ../lib/careadlinkat.h.
20034 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
20036 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

20058 do not dereference NULL upon failed strdup
20059 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
20060 (ns_get_family): Likewise.
20062 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
20064 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
20066 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
20068 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
20071 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
20073 Add lexical binding.
20075 * window.c (Ftemp_output_buffer_show): New fun.
20076 (Fsave_window_excursion):
20077 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.

20082 Bind Qinternal_interpreter_environment.
20083 (Feval_buffer): Bind Qlexical_binding.
20084 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
20086 (syms_of_lread): Declare `lexical-binding'.
20088 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
20090 * keyboard.c (eval_dyn): New fun.
20091 (menu_item_eval_property): Use it.
20093 * image.c (parse_image_spec): Use Ffunctionp.
20095 * fns.c (concat, mapcar1): Accept byte-code-functions.
20097 * eval.c (Fsetq): Handle lexical vars.
20098 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
20099 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
20100 (FletX, Flet): Obey lexical binding.
20101 (Fcommandp): Handle closures.
20102 (Feval): New `lexical' arg.
20103 (eval_sub): New function extracted from Feval. Use it almost
20104 everywhere where Feval was used. Look up vars in lexical env.
20106 (Ffunctionp): Move from subr.el.
20107 (Ffuncall): Handle closures.
20108 (apply_lambda): Remove `eval_flags'.
20109 (funcall_lambda): Handle closures and new byte-code-functions.
20110 (Fspecial_variable_p): New function.
20111 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
20112 but without exporting it to Lisp.
20114 * doc.c (Fdocumentation, store_function_docstring):
20115 * data.c (Finteractive_form): Handle closures.
20117 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
20120 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
20122 (exec_byte_code): New function extracted from Fbyte_code to handle new
20123 calling convention for byte-code-functions. Add new byte-codes.
20125 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
20127 * alloc.c (Fmake_symbol): Init new `declared_special' field.
20129 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
20131 * xdisp.c (redisplay_internal): Fix prototype.
20133 2011-03-31 Eli Zaretskii <eliz@gnu.org>
20135 * xdisp.c (SCROLL_LIMIT): New macro.
20136 (try_scrolling): Use it when setting scroll_limit.
20137 Limit scrolling to 100 screen lines.
20138 (redisplay_window): Even when falling back on "recentering",
20139 position point in the window according to scroll-conservatively,
20140 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
20142 (try_scrolling): When point is above the window, allow searching
20143 as far as scroll_max, or one screenful, to compute vertical
20144 distance from PT to the scroll margin position. This prevents
20145 try_scrolling from unnecessarily failing when
20146 scroll-conservatively is set to a value slightly larger than the
20147 window height. Clean up the case of PT below the margin at bottom
20148 of window: scroll_max can no longer be INT_MAX. When aggressive
20149 scrolling is in use, don't let point enter the opposite scroll
20150 margin as result of the scroll.
20151 (syms_of_xdisp) <scroll-conservatively>: Document the
20152 threshold of 100 lines for never-recentering scrolling.
20154 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

20159 (message_log_check_duplicate): Remove parameters `prev_bol' and
20160 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
20161 (redisplay_internal): Remove parameter `preserve_echo_area',
20162 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
20164 * indent.c (Fvertical_motion):
20165 * window.c (window_scroll_pixel_based, Frecenter):
20166 Don't pass `need_y_p' to `move_it_by_lines'.
20168 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
20170 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
20171 steal a few bits to be more compact.
20172 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
20173 Remove unneeded casts.
20175 * bytecode.c (Fbyte_code): CAR and CDR can GC.
20177 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
20179 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
20180 binding" message (bug#7967).
20182 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
20184 Fix more problems found by GCC 4.6.0's static checks.
20186 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
20187 Remove unused local var.
20189 * editfns.c (Fmessage_box): Remove unused local var.
20191 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
20192 (note_mode_line_or_margin_highlight, note_mouse_highlight):
20193 Omit unused local vars.
20194 * window.c (shrink_windows): Omit unused local var.
20195 * menu.c (digest_single_submenu): Omit unused local var.
20196 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
20197 Omit unused local var.
20199 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
20200 Don't assume string length fits in int.
20201 (keyremap_step, read_key_sequence): Use size_t for sizes.

20204 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
20205 instead of alloca (Bug#8344).
20207 * eval.c (Fbacktrace): Don't assume nargs fits in int.
20208 (Fbacktrace_frame): Don't assume nframes fits in int.
20210 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

20217 * cm.c (calccost): Turn while-do into do-while, for clarity.
20219 * keyboard.c (syms_of_keyboard): Use the same style as later
20220 in this function when indexing through an array. This also
20221 works around GCC bug 48267.
20223 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
20225 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
20227 * chartab.c (sub_char_table_ref_and_range): Redo for slight
20228 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
20230 * keyboard.c, keyboard.h (num_input_events): Now size_t.
20231 This avoids undefined behavior on integer overflow, and is a bit
20232 more convenient anyway since it is compared to a size_t variable.
20234 Variadic C functions now count arguments with size_t, not int.
20235 This avoids an unnecessary limitation on 64-bit machines, which
20236 caused (substring ...) to crash on large vectors (Bug#8344).

20246 * fns.c (concat): Likewise.
20247 * frame.c (x_set_frame_parameters): Likewise.
20248 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
20249 0 if not found, not -1. All callers changed.
20251 * alloc.c (garbage_collect): Don't assume stack size fits in int.
20252 (stack_copy_size): Now size_t, not int.
20253 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
20255 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
20257 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
20258 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

20274 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
20275 don't set the hook to nil, but remove the offending function instead.
20276 (Qcommand_hook_internal): Remove, unused.
20277 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
20278 Vcommand_hook_internal.
20280 * eval.c (enum run_hooks_condition): Remove.
20281 (funcall_nil, funcall_not): New functions.
20282 (run_hook_with_args): Call each function through a `funcall' argument.

20296 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.

20446 2011-03-23 Julien Danjou <julien@danjou.info>
20448 * term.c (Fsuspend_tty, Fresume_tty):
20449 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
20450 * window.c (temp_output_buffer_show):
20451 * insdel.c (signal_before_change):
20452 * frame.c (Fhandle_switch_frame):
20453 * fileio.c (Fdo_auto_save):
20454 * emacs.c (Fkill_emacs):
20455 * editfns.c (save_excursion_restore):
20456 * cmds.c (internal_self_insert):
20457 * callint.c (Fcall_interactively):
20458 * buffer.c (Fkill_all_local_variables):
20459 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
20461 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
20462 unconditionally since it does the check itself.
20464 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
20466 Fix more problems found by GCC 4.5.2's static checks.
20468 * coding.c (encode_coding_raw_text): Avoid unnecessary test
20469 the first time through the loop, since we know p0 < p1 then.
20470 This also avoids a gcc -Wstrict-overflow warning.
20472 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
20473 leading to a memory leak, possible in functions like
20474 load_charset_map_from_file that can allocate an unbounded number
20475 of objects (Bug#8318).
20477 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
20478 that could (at least in theory) be that large.
20480 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
20481 This is less likely to overflow, and avoids undefined behavior if
20482 overflow does occur. All callers changed. Use strtoul to scan
20483 for the unsigned long integer.
20484 (pint2hrstr): Simplify and tune code slightly.
20485 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
20487 * scroll.c (do_scrolling): Work around GCC bug 48228.
20488 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
20490 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
20491 This also avoids a warning with gcc -Wstrict-overflow.
20492 (validate_x_resource_name): Simplify count usage.
20493 This also avoids a warning with gcc -Wstrict-overflow.
20495 * fileio.c (Fcopy_file): Report error if fchown or fchmod
20498 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
20500 * process.c (Fmake_network_process): Use socklen_t, not int,
20501 where POSIX says socklen_t is required in portable programs.
20502 This fixes a porting bug on hosts like 64-bit HP-UX, where
20503 socklen_t is wider than int (Bug#8277).
20504 (Fmake_network_process, server_accept_connection):
20505 (wait_reading_process_output, read_process_output):
20508 * process.c: Rename or move locals to avoid shadowing.
20509 (list_processes_1, Fmake_network_process):
20510 (read_process_output_error_handler, exec_sentinel_error_handler):
20511 Rename or move locals.
20512 (Fmake_network_process): Define label "retry_connect" only if needed.
20513 (Fnetwork_interface_info): Fix pointer signedness.
20514 (process_send_signal): Add cast to avoid pointer signedness problem.
20515 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
20516 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
20518 Make tparam.h and terminfo.c consistent.
20519 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
20520 Include tparam.h instead, since it declares them.
20521 * cm.h (PC): Remove extern decl; tparam.h now does this.
20522 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
20523 * terminfo.c: Include tparam.h, to check interfaces.
20524 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
20525 (tparam): Adjust signature to match interface in tparam.h;
20526 this removes some undefined behavior. Check that outstring and len
20527 are zero, which they always are with Emacs.
20528 * tparam.h (PC, BC, UP): New extern decls.
20530 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
20531 (xftfont_open): Rename locals to avoid shadowing.
20533 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
20534 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
20535 (OTF_TAG_SYM): Omit macro if not needed.
20536 (ftfont_list): Remove unused local.
20537 (get_adstyle_property, ftfont_pattern_entity):
20538 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
20539 Rename locals to avoid shadowing.
20541 * xfont.c (xfont_list_family): Mark var as initialized.
20543 * xml.c (make_dom): Now static.
20545 * composite.c (composition_compute_stop_pos): Rename local to
20547 (composition_reseat_it): Remove unused locals.
20548 (find_automatic_composition, composition_adjust_point): Likewise.
20549 (composition_update_it): Mark var as initialized.
20550 (find_automatic_composition): Mark vars as initialized,
20551 with a FIXME (Bug#8290).
20553 character.h: Rename locals to avoid shadowing.
20554 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
20555 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
20556 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
20557 (BUF_DEC_POS): Be more systematic about renaming local temporaries
20558 to avoid shadowing.
20560 * textprop.c (property_change_between_p): Remove; unused.
20562 * intervals.c (interval_start_pos): Now static.
20564 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

20567 Rename locals to avoid shadowing.
20569 * sound.c (wav_play, au_play, Fplay_sound_internal):
20570 Fix pointer signedness.
20571 (alsa_choose_format): Remove unused local var.
20572 (wav_play): Initialize a variable to 0, to prevent undefined
20573 behavior (Bug#8278).
20575 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
20577 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
20579 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
20580 clobbering (Bug#8298).
20581 * sysdep.c (sys_subshell): Likewise.
20582 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
20584 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
20585 This should get cleaned up, so that child_setup has the
20586 same signature on all platforms.
20588 * callproc.c (call_process_cleanup): Now static.
20589 (relocate_fd): Rename locals to avoid shadowing.
20591 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
20593 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
20594 not to be necessary, and produces flickering.
20596 2011-03-20 Glenn Morris <rgm@gnu.org>
20598 * config.in: Remove file.
20600 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
20602 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
20603 are now in src/globals.h.
20604 (syms_of_minibuf): Remove spurious & from previous change.
20606 2011-03-20 Leo Liu <sdl.web@gmail.com>
20608 * minibuf.c (completing-read-function): New variable.
20609 (completing-read-default): Rename from completing-read.
20610 (completing-read): Call completing-read-function.
20612 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
20614 * xfaces.c (Fx_load_color_file):
20615 Read color file from absolute filename (bug#8250).
20617 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
20619 * makefile.w32-in: Update dependencies.
20621 2011-03-17 Eli Zaretskii <eliz@gnu.org>
20623 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

20627 Fix more problems found by GCC 4.5.2's static checks.
20629 * process.c (make_serial_process_unwind, send_process_trap):
20630 (sigchld_handler): Now static.
20632 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
20633 That way, the code declares only the vars that it needs.
20634 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
20635 * s/cygwin.h (PTY_ITERATION): Likewise.
20636 * s/darwin.h (PTY_ITERATION): Likewise.

20639 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
20640 * process.c (allocate_pty): Don't declare stb unless it's needed.
20642 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
20643 (CONSTANTLIM): Remove; unused.
20644 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
20645 Define only if needed.
20647 * unexelf.c (unexec): Name an expression,
20648 to avoid gcc -Wbad-function-cast warning.
20649 Use a different way to cause a compilation error if anyone uses
20650 n rather than nn, a way that does not involve shadowing.
20651 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
20653 * deps.mk (unexalpha.o): Remove; unused.
20655 New file unexec.h, the (simple) interface for unexec (Bug#8267).
20656 * unexec.h: New file.
20657 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
20658 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
20659 Depend on unexec.h.
20660 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
20661 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
20662 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
20663 Change as necessary to match prototype in unexec.h.
20665 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
20667 (back_comment, skip_chars): Mark vars as initialized.
20669 * character.h (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS):

20675 * print.c (Fredirect_debugging_output): Fix pointer signedess.
20677 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
20678 warning when compiling print.c.

20681 instead of using an uninitialized var.
20682 (font_sort_entities): Mark var as initialized.
20684 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
20686 * font.c (font_unparse_xlfd): Don't mix pointers to variables with
20687 pointers to constants.

20698 * floatfns.c (domain_error2): Define only if needed.
20699 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
20701 * alloc.c (mark_backtrace): Move decl from here ...
20702 * lisp.h: ... to here, so that it can be checked.
20704 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
20705 (Fdefvar): Rewrite so as not to use empty "else".
20706 (lisp_indirect_variable): Name an expression,
20707 to avoid gcc -Wbad-function-cast warning.

20710 * callint.c (quotify_arg, quotify_args): Now static.
20711 (Fcall_interactively): Rename locals to avoid shadowing.
20712 Use const pointer when appropriate.
20714 * lisp.h (get_system_name, get_operating_system_release):

20716 * process.c (get_operating_system_release): Move decl to lisp.h.
20717 * xrdb.c (get_system_name): Likewise.
20718 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
20719 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
20720 some of which prompt warnings from gcc -Wbad-function-cast.
20721 (Fformat_time_string, Fencode_time, Finsert_char):
20722 (Ftranslate_region_internal, Fformat):
20723 Rename or remove local vars to avoid shadowing.
20724 (Ftranslate_region_internal): Mark var as initialized.
20726 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
20729 * lisp.h (eassert): Check that the argument compiles, even if
20730 ENABLE_CHECKING is not defined.
20732 * data.c (Findirect_variable): Name an expression, to avoid
20733 gcc -Wbad-function-cast warning.
20734 (default_value, arithcompare, arith_driver, arith_error): Now static.

20741 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
20742 Rename locals to avoid shadowing.
20743 (mark_stack): Move local variables into the #ifdef region where
20745 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
20746 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
20748 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
20749 (GC_STRING_CHARS): Remove; not used.
20750 (Fmemory_limit): Cast sbrk's returned value to char *.
20752 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
20753 avoids undefined behavior in theory.
20755 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
20757 Use functions, not macros, for up- and down-casing (Bug#8254).
20758 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20759 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
20760 to use the following functions instead of these macros.
20761 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
20762 EMACS_INT, since callers assume the returned value fits in int.
20763 (upcase1): Likewise, for UPCASE_TABLE.
20764 (uppercasep, lowercasep, upcase): New static inline functions.
20765 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
20766 the race-condition problem in the old DOWNCASE.
20768 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
20769 Rename locals to avoid shadowing.
20770 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
20771 (regex_compile, re_search_2, re_match_2_internal):
20772 Remove unused local vars.
20773 (FREE_VAR): Rewrite so as not to use empty "else",
20774 which gcc can warn about.
20775 (regex_compile, re_match_2_internal): Mark locals as initialized.
20776 (RETALLOC_IF): Define only if needed.
20777 (WORDCHAR_P): Likewise. This one is never needed, but is used
20778 only in a comment talking about a compiler bug, so put inside
20779 the #if 0 of that comment.
20780 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
20781 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
20784 * search.c (boyer_moore): Rename locals to avoid shadowing.
20785 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
20786 (PREV_CHAR_BOUNDARY): Likewise.
20788 * search.c (simple_search): Remove unused var.
20790 * dired.c (compile_pattern): Move decl from here ...

20794 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
20796 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
20798 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
20799 Rename locals to avoid shadowing.
20800 (Fvertical_motion): Mark locals as initialized.
20802 * casefiddle.c (casify_object, casify_region): Now static.
20803 (casify_region): Mark local as initialized.
20805 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
20807 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
20808 New macros, so that the caller can use some names other than
20809 gcpro1, gcpro2, etc.
20810 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
20812 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
20813 argument, for consistency with GCPRO2_VAR, etc: it is now the
20814 prefix of the variable, not the variable itself. All uses
20816 * dired.c (directory_files_internal, file_name_completion):
20817 Rename locals to avoid shadowing.
20819 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
20820 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
20821 dired.c's scmp function, had undefined behavior.
20822 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
20823 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
20824 * buffer.h: ... to here, because these macros use current_buffer,
20825 and the new implementation with inline functions needs to have
20826 current_buffer in scope now, rather than later when the macros
20828 (downcase, upcase1): New static inline functions.
20829 (DOWNCASE, UPCASE1): Reimplement using these functions.
20830 This avoids undefined behavior in expressions like
20831 DOWNCASE (x) == DOWNCASE (y), which previously suffered
20832 from race conditions in accessing the global variables
20833 case_temp1 and case_temp2.
20834 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
20835 * lisp.h (case_temp1, case_temp2): Remove their decls.
20836 * character.h (ASCII_CHAR_P): Move from here ...
20837 * lisp.h: ... to here, so that the inline functions mentioned
20838 above can use them.
20840 * dired.c (directory_files_internal_unwind): Now static.
20842 * fileio.c (file_name_as_directory, directory_file_name):
20843 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
20845 (file_name_as_directory): Use const pointers when appropriate.
20846 (Fexpand_file_name): Likewise. In particular, newdir might
20847 point at constant storage, so make it a const pointer.
20848 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
20849 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
20851 (Fset_file_times, Finsert_file_contents, auto_save_error):
20852 Rename locals to avoid shadowing.
20854 * minibuf.c (choose_minibuf_frame_1): Now static.
20855 (Ftry_completion, Fall_completions): Rename or remove locals
20856 to avoid shadowing.
20858 * marker.c (bytepos_to_charpos): Remove; unused.
20860 * lisp.h (verify_bytepos, count_markers): New decls,
20861 so that gcc does not warn that these functions aren't declared.
20863 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
20864 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
20865 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
20866 (copy_text): Remove unused local var.
20868 * filelock.c (within_one_second): Now static.
20869 (lock_file_1): Rename local to avoid shadowing.
20871 * buffer.c (fix_overlays_before): Mark locals as initialized.
20872 (fix_start_end_in_overlays): Likewise. This function should be
20873 simplified by using pointers-to-pointers, but that's a different
20875 (switch_to_buffer_1): Now static.
20876 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
20877 (report_overlay_modification): Rename locals to avoid shadowing.
20879 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
20880 Fix pointer signedness issue.
20881 (sys_subshell): Mark local as volatile if checking for lint,
20882 to suppress a gcc -Wclobbered warning that does not seem to be right.
20883 (MAXPATHLEN): Define only if needed.
20885 * process.c (serial_open, serial_configure): Move decls from here ...
20886 * systty.h: ... to here, so that they can be checked.
20888 * fns.c (get_random, seed_random): Move extern decls from here ...
20889 * lisp.h: ... to here, so that they can be checked.
20891 * sysdep.c (reset_io): Now static.
20892 (wait_for_termination_signal): Remove; unused.
20894 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
20895 (copy_keymap_item, append_key, push_text_char_description):
